Title: Hose reel

Description:
TECHNICAL FIELD  
      The present invention relates to a hose reel for winding up a hose.  
     BACKGROUND ART  
      Conventionally, a hose reel is used for winding up a hose for sprinkling use (see for instance Japanese Patent Laid-Open No. 2001-206637 ( FIG. 1 ) and Japanese Patent Laid-Open No. 2001-206638 ( FIG. 1 )).  
      This hose reel would be composed of a frame and a drum rotatably supported by the frame. The frame consists of triangular side plates disposed opposite each other, and the two side plates are linked with a space between them. A connecting plug for connecting the faucet side hose protrudes from one of these side plates, and a handle for turning the drum protrudes from the other.  
      It is so configured as to wind up and keep the hose around the drum by turning this handle.  
      However, as the side plates constituting the frame are disposed with a space between them in this hose reel, the hose winding side is open. As a result, the hose wound around the drum is apt to become disorderly in the wound state.  
      Also, there is another type of hose reel consisting of a frame and a drum rotatably supported by the frame, and the frame consists of right and left side plates and pipe members linking the two side plates.  
      Further, the drum is formed of a barrel around which the hose is to be wound and collars disposed at the two ends of the barrel.  
      However, as the hose winding side is open in this hose reel, the hose is apt to be wound into the gap between the drum and the frame.  
      A hose can be neatly wound by neither of these conventional hose reels. An object of the present invention, attempted in view of these problems with the conventional reels, is to provide a hose reel that can neatly wind up a hose.  
     DISCLOSURE OF THE INVENTION  
      In order to solve the problem noted above, a hose reel according to Claim  1  of the present invention is a hose reel for winding a hose by turning a drum, wherein a guide part for guiding the hose is provided on the moving path of the hose to be wound around the drum and the width of the guide part is so set as to decrease toward its upper portion.  
      Thus, when the hose is wound by turning the drum, the hose may sometimes concentrate on one end of the drum. However, the guide part for guiding the hose is provided on the moving path of the hose, and the width of the guide part is so set as to decrease toward its upper portion.  
      As a result, the hose wound concentrating on an end of the drum is guided along the guide part toward the central part when a prescribed quantity has been wound up.  
      A hose reel according to Claim  2  of the invention is a hose reel for winding a hose by turning a drum, wherein a guide part for guiding the hose is provided on the moving path of the hose to be wound around the drum, a restrictive part for preventing the hose from escaping is extended on the guide part in a direction crossing the moving direction of the hose, an inclined part inclined toward the central part along its upper direction is set on the restrictive part, and the angle of inclination in the inclined part is set to be not less than 45 degrees and less than 90 degrees.  
      Thus, when the hose is wound by turning the drum, the hose may sometimes concentrate on one end of the drum. However, the guide part for guiding the hose is provided on the moving path of the hose, and an inclined part inclined toward the central part along its upper direction is set on the restrictive part set on the guide part.  
      As a result, the hose wound concentrating on an end of the drum is guided by the inclined part toward the central part when a prescribed quantity has been wound up.  
      Then, a downward component of force and a horizontal component of force arise in the hose that has come into contact with this inclined part, and the angle of inclination of the inclined part is set to be not less than 45 degrees and less than 90 degrees. For this reason, the horizontal component of force is not less than the downward component of force, and the force guiding the hose stacked to a prescribed quantity toward the central part is not less than the force pressing the hose downward.  
      Further, a hose reel according to Claim  3  of the invention is a hose reel for winding a hose by turning a drum, wherein a guide part for guiding the hose is provided on the moving path of the hose to be wound around the drum, a restrictive part for preventing the hose from escaping is extended on the guide part in a direction crossing the moving direction of the hose, and the restrictive part is formed in an arc shape whose central part protrudes.  
      Thus, when the hose is wound by turning the drum, the hose may sometimes concentrate on one end of the drum. However, the guide part for guiding the hose is provided on the moving path of the hose, and the restrictive part set on the guide part is formed in an arc shape whose central part protrudes.  
      As a result, the hose wound concentrating on an end of the drum is guided along the guide part in an arc shape toward the central part when a prescribed quantity has been wound up.  
      Further, in a hose reel according to Claim  4  of the invention, an opening through which the hose is inserted is provided in the guide part, the restrictive part is set in the upper opening edge of the opening, and the lower opening edge of the opening is linearly formed.  
      Thus, of starting winding of the hose around an empty drum, the hose to be moved is guided along the lower opening edge of the opening in the guide part. In this arrangement this lower opening edge is linearly formed. As a result, the hose is wound around the whole area of the drum in a distributed way.  
      And when a prescribed quantity of the hose has been wound up around the drum, it is guided along the restrictive part formed by the upper opening edge of the opening in the guide part.  
      Further in a hose reel according to Claim  5  of the invention, the drum is supported by a frame, and the guide part is composed of a bar disposed on the frame.  
      This contributes to simplification of the configuration.  
      Further in a hose reel according to Claim  6  of the invention is a hose reel for winding a hose by turning a drum, wherein a guide part having an opening through which the hose is inserted is provided on the moving path of the hose to be wound around the drum, and a thick part thicker than a general part is disposed on the opening edge of the opening.  
      Thus, the hose to be wound up by the drum is guided to its prescribed position by being inserted through the opening disposed in the guide part and brought into sliding contact with the opening edge of the opening.  
      Herein, a thick part thicker than a general part is disposed on the opening edge of the opening. As a result, inadvertent bending of the hose can be more securely prevented than in a case in which the opening edge is composed of a thin part.  
      Further, a hose reel according to Claim  7  of the invention is a hose reel for winding a hose by turning a drum, wherein a guide part having an opening through which the hose is inserted is provided on the moving path of the hose to be wound around the drum, and the sectional shape of the opening edge of the opening is formed in an arc protruding toward the center of the opening.  
      Thus, the hose to be wound up by the drum is guided to its prescribed position by being inserted through the opening disposed in the guide part and brought into sliding contact with the opening edge of the opening.  
      Herein, the opening edge of the opening is formed in an arc having a sectional shape protruding toward the center of the opening. As a result, the area of contact with the hose in sliding contact is reduced.  
      In addition, a hose reel according to Claim  8  of the invention is a hose reel for winding a hose by turning a drum, wherein a rotational member in contact with the hose and rotating in the direction of urging the movement of the hose is disposed on the moving path of the hose to be wound up by the drum.  
      Thus, the hose to be wound up by the drum comes into contact with the rotational member disposed on the moving path of the hose. This rotational member is in contact with the hose and rotates in the direction of urging the movement of the hose. In this way, the hose is guided by the rotational member to the drum.  
      And in a hose reel according to Claim  8  of the invention the outer circumferential face of the hose is made rugged.  
      Thus, when the hose is wound up, the outer circumferential face of the hose comes into sliding contact with the inner face of the drum or that of the frame and gives rise to friction. However, as the outer circumferential face of this hose is rugged, the frictional resistance to the area of sliding contact is reduced. The winding of the hose around the drum is further smoothened, and disorderly winding is prevented.  
      Further in a hose reel according to Claim  10  of the invention wherein a drum having collars at the two ends of its barrel is turnably supported by a frame, the frame is formed in a shape allowing accommodation of the drum, an inlet/outlet for the hose is disposed in a position in the frame opposite the winding position between the two collars of the drum, and the width of the inlet/outlet is set to be not greater than the distance from one collar of the drum to the other.  
      Thus, the inlet/outlet for the hose is disposed in the position in the frame opposite the winding position between the two collars of the drum, and the hose to be wound up by the drum moves via this inlet/outlet.  
      And the width of this inlet/outlet is set to be not greater than the distance from one collar of the drum to the other. As a result, the hose to be accommodated into the frame via the inlet/outlet is guided to the position between the two collars of the drum.  
      Further in a hose reel according to Claim  11  of the invention, the frame is formed in a case shape for accommodating the drum.  
      Thus, the frame turnably supporting the drum is formed in the case shape allowing accommodation of the drum, the inlet/outlet for the hose is disposed in the position in the frame opposite the winding position between the two collars of the drum, and the hose to be wound up by the drum moves via this inlet/outlet.  
      And the width of the inlet/outlet is set to be not greater than the distance from one collar of the drum to the other. As a result, the hose accommodated into the frame via the inlet/outlet is guided to the position between the two collars of the drum.  
      Further in a hose reel according to Claim  12  of the invention, the width of the inlet/outlet is set to decrease toward the upper part.  
      Preferably, as stated in Claim  13  of the invention, the opening edge of the inlet/outlet on the upper side should be formed in an arc shape whose central part protrudes upward.  
      Thus, when the hose is wound by turning the drum, the hose may sometimes concentrate on the collar at one end of the drum. However, as the width of the inlet/outlet through which the hose moves is set to decrease toward the upper part, and preferably the opening edge of the inlet/outlet on the upper side is formed in an arc shape whose central part protrudes upward.  
      As a result, the hose wound concentrating on the end of the drum is guided along the opening edge of the inlet/outlet, preferably along an opening edge in the arc shape, toward the central part when a prescribed quantity has been wound up.  
      In addition, in a hose reel according to Claim  14  of the invention, the starting point of the arc shape of the opening edge is set between the center of rotation of the drum and the highest position of the collars.  
      As a result, the hose to be wound concentrating on the collars side of the end of the drum, before reaching the highest position of the collars, is guided toward the central part along the opening edge of the arc shape.  
      Further in a hose reel according to Claim  15  of the invention, a drum having collars at the two ends of its barrel is turnably supported by a frame, the distance between the two collars is set between 40% and 60% of the diameter of the collars.  
      Thus, the distance between the two collars provided at the two ends of the barrel of the drum around which the hose is to be wound is set between 40% and 60% of the diameter of the collars. When the hose is wound around such a drum, even if the hose is wound concentrating on one of the collars, a collapse will arise within. For this reason, the hose is guided to a position between the two collars by being wound around this drum.  
      Herein, though the winding ease of the hose can be improved by reducing the distance between the collars of the drum, but if the distance between the collars is made too small, the drum will become thin and apt to fall down. In view of this factor, repeated experiments have led to a discovery that the two requirements can be made consistent with each other by setting the distance between the collars of the drum to between 40% and 60% of the diameter of the collars.  
      As a result, the invention according to which the distance between the collars of the drum is set to between 40% and 60% of the diameter of the collars enables the winding ease to be improved without sacrificing the resistance of the drum to falling down.

     BEST MODES FOR CARRYING OUT THE INVENTION  
      The present invention will be described in more detail with reference to the accompanying drawings.  
     First Embodiment  
      A first mode for implementing the invention will be described below with reference to drawings.  FIG. 1  shows a hose reel  1  in this embodiment, the hose reel  1  being intended for use in winding up a hose for the sprinkling purpose.  
      This hose reel  1  is provided with a rectangular body case  11  constituting a frame, and the body case  11  as shown in  FIG. 2 , formed by coupling a lower vessel  12  of a container shape opening upward and an upper vessel  13  of a container shape opening downward. This body case  11 , as shown in  FIG. 3 , accommodates a drum  15  for winding up a hose  14 , and the drum  15  comprises a cylindrical barrel  17  around which the hose  14  having penetrated a hose inserting hole  16  is wound and collars  18  and  18  disposed at the two ends of the barrel  17 .  
      The top plate  21  of the upper vessel  13 , as shown in  FIG. 1  and  FIG. 4 , is formed in a rectangular flat shape. The top plate  21 , set to be large enough to permit the mounting of another hose reel on the body case  11 , constitutes a load carrier.  
      A C-shaped concave  22  is formed in this top plate  21 , and a C-shaped handle  23  is arranged in the concave  22 . The handle  23  is composed of a grip  24  constituting a free end and extension parts  25  and  25  extending from the two ends of the grip  24  into the C shape, and turnably supported by the upper vessel  13  via rotation shafts  26  and  26  disposed at the tips of the extension parts  25  and  25  as shown in  FIG. 5 . In this way, the handle  23  is so configured as to be turnable between an inclined state  27  in which it is accommodated in the concave  22  and an erect state  28  in which it is erect.  
      These extension parts  25  and  25  of the handle  23  are so configured that its turning is restricted as it comes into contact, in its erect state  28 , with a contact part  29  consisting of the upper edge of the concave  22 , and the contact part  29  is composed of an inclined face which inclined forward. The handle  23  is so configured that, in this erect state  28 , its turning is restricted at a prescribed angle a beyond 90 degrees, more specifically 109 degrees from the inclined state  27 . By virtue of this arrangement, when the handle  23  in the inclined state  27  is to be shifted to the erect state  28 , after the grip  24  constituting the free end of the handle  23  passes above the center of turning consisting of the rotation shafts  26 , the extension parts  25  and  25  stop in a forward incline state in contact with the contact part  29 .  
      On the moving path of the hose  14  wound up by the drum  15 , the path being the front face  31  of the upper vessel  13 , a guide part  32  for guiding the hose  14  is disposed as shown in  FIG. 6 . The guide part  32  is provided with an inlet/outlet  33  as an opening through which the hose  14  is inserted, and the upper opening edge of the inlet/outlet  33  constitutes an upper restrictive part  34  to prevent the hose  14  from escaping upward. The upper restrictive part  34  extends in a direction crossing the moving direction I of the hose  14  that is wound up (see  FIG. 1 ), and the upper restrictive part  34  is formed in an arch shape, protruding upward in its central part.  
      Incidentally, although the guide part according to the invention is configured by forming the inlet/outlet  33  in the front face  31  in this embodiment, this guide part can as well be formed by cutting a notch downward in the lower edge of a plate-shaped member or configured of a pipe formed in an angle or trapezoidal shape.  
      The upper restrictive part  34  is so set that the width W of the lower side hose passage formed by the upper restrictive part  34  is thereby set to become smaller toward the upper part.  
      To add, though the example described above is a case in which the upper restrictive part  34  is formed of the upper opening edge of the inlet/outlet  33 , this is not the only possibility, but it may configured of a long member curbed in an arch shape.  
      Also, the lower opening edge of the inlet/outlet  33  may as well be open.  
      A bottom  35  is formed throughout the area of this upper restrictive part  34  as shown in  FIG. 5 , and the bottom  35  protrudes outward from the body case  11 . The position of the upper restrictive part  34  in its highest area is set to be lower than the highest area in the collars  18  of the drum  15  supported by the body case  11 , and an allowance Y for hose winding is set between the highest area in the upper restrictive part  34  and the highest area in the collars  18 .  
      The lower opening edge of the inlet/outlet  33 , as shown in  FIG. 6 , is linearly formed to constitute a lower restrictive part  36  to allow the hose  14  to move in the lateral direction. The inlet/outlet  33  is thereby formed in a semicircular shape whose arch-shaped part is positioned at the top.  
      The lower restrictive part  36  constituting the opening edge of the inlet/outlet  33  is formed thicker than the general part  37  as shown in  FIG. 5  to constitute a thick part  38 . This thick part  38  is arch-shaped in sectional shape, protruding toward the center of the inlet/outlet  33 , and is so configured that the hose  14  moving within the inlet/outlet  33  come into line contact with it.  
      At the joints between the lower ends of the left and right sides  41  and  42  of this upper vessel  13  and the upper ends of the left and right sides  43  and  44  of the lower vessel  12 , there are formed bulgy parts  45  and  45  bulging sideways, which constitute a circular form when joined together, as shown in  FIG. 1  and  FIG. 6 , and end parts of the barrel  17 , protruding from the collars  18  and  18  of the drum  15 , are rotatably supported between the bulgy parts  45  and  45  as shown in  FIG. 3 . Round holes  46  and  46  are provided at the centers of these bulgy parts  45  and  45 , and the shaft  48  of a crank-shaped handle  47  for turning the drum  15  is inserted into the round hole  46  of the bulgy part  45  arranged on the left side.  
      Also, a connecting plug  51  for connecting the faucet side hose is inserted into the round hole  46  of the bulgy part  45  arranged on the right side, and one end of a pipe member  52  to be connected to the hose  14  wound around the drum  15  is connected to the connecting plug  51 . This configuration enables running water from the faucet to be supplied to the pipe member  52  via the connecting plug  51  and to the hose  14  on the sprinkling side, wound around the drum  15 , via the pipe member  52 .  
      A rectangular bottom opening  62  is cut in the bottom  61  of the lower vessel  12  as shown in  FIG. 7 , and the body case  11  communicates with outside via this bottom opening  62 .  
      Laterally long leg-fixing members  65  and  65  are screwed on along the edges of the front and rear face sides of the bottom  61 . Cross-shaped shafts  66  and  66  protrude in mutually opposite direction at the two ends of the leg fixing members  65  and  65  as shown in  FIG. 8 , and legs  67  and  67  formed in the same shape are rotatably supported by the opposite shafts  66  and  66 .  
      At both ends of these legs  67 , cylindrical parts  71  and  71  to externally fit onto the shafts  66  and  66  are formed in base ends  72 , and top face parts  73  extending toward the tips are integrally formed with these cylindrical parts  71 . The legs  67  and  67  are so configured as to be able to form as desired by turning around the cylindrical parts  71  and  71  a folded state  74  in which, as shown in  FIG. 9 , the tips of both legs  67  and  67  are arranged underneath the body case  11  and both legs  67  and  67  are arranged underneath the bottom opening  62  or a developed state  75  in which, as shown in  FIG. 1 , the tips of both legs  67  and  67  extend sideways from the body case  11  and are in contact with the bottom  61  of the body case  11  (see  FIG. 8 ) to be restricted in turning.  
      The configuration is such that the erect state of the body case  11  can be thereby stabilized in the developed state  75  and, in the folded state  74 , the bottom opening  62  cut in the bottom  61  can be closed by the legs  67  and  67 .  
      The top face parts  73  are formed in such lengths that, when one leg  67  is folded ahead of the other leg  67  to constitute the folded state  74  shown in  FIG. 9 , the parts of the two legs  67  and  67  farther out than the base ends  72  and  72  overlap each other, and on their rear faces a plurality of the ribs  81 , . . . and flanges  82  and  82  extending from their two side edges are integrally formed. The heights of these flanges  82  and  82  and the ribs  81 , . . . are set to become lower from the base ends  72  toward the tips as shown in  FIG. 8 , and the thickness of each leg  67  is set to become thinner from the base ends  72  pivoting on the body case  11  toward the tip.  
      Further, the thickness of the legs  67  and  67  in their overlapping parts  83 , as shown in  FIG. 9 , is so set that the sum of their thickness counts overlapping each other in the folded state  74  be not greater than the greatest thickness of the legs  67  and  67 , i.e. at the base ends  72 , resulting in a configuration in which the legs  67  and  67  are positioned above the under faces of the leg fixing members  65  in the folded state  74 .  
      And as shown in  FIG. 5 , two ribs  92  and  92  extend from the bottom  61  toward the upper opening on an inner side face  91  of he lower vessel  12  of the body case  11 , and two ribs  94  and  94  also extend from the top plate  21  toward the lower opening on an inner side face  93  of the upper vessel  13  of the body case  11 . Thus, these ribs  92 ,  92 ,  94  and  94  extend in the direction of mold drawing when the vessels  12  and  13  are molded of resin.  
      The heights H of the ribs  92 ,  92 ,  94  and  94 , as shown in  FIG. 3 , are set to be not less than the separation distance R from each of the inner side faces  91  and  93  to the collars  18  of the drum  15 , the lengths of the ribs  92 ,  92 ,  94  and  94 , as shown in  FIG. 5 , are so set as to bring their tips close to the collars  18 .  
      In this embodiment using the configuration described above, when the hose  14  is to be wound up by turning the drum  15  with the handle  47 , the hose  14  may sometimes concentrate on one end of the drum  15 , i.e. on the side of one of the collars  18 . However, the guide part  32  for guiding the hose  14  is disposed on the moving path of the hose  14 , and the central part of the upper restrictive part  34  set on the guide part  32  has an arch-shaped bulging upward. In other words, the width W of the passage for the hose  14  formed underneath the upper restrictive part  34  is so set as to decrease upward.  
      For this reason, when the hose  14  wound concentrating around an end of the drum  15  reaches a prescribed height, the hose  14  can be guided toward the central part along the upper restrictive part  34  in the arch-shaped whose the width W decreases upward.  
      Therefore, it is possible to prevent disorderly winding of the hose  14 , its concentration around one end of the drum  15  and to wind up the hose  14  neatly. This also contributes to improve the appearance of the wound state of the hose and to prevent deviation of the center of gravity.  
      On the other hand, at the time of starting winding of the hose  14  around an empty drum  15 , around which no hose  14  is wound yet, it is possible to guide this hose  14  along the lower restrictive part  36  formed by the lower opening edge of the inlet/outlet  33  in the guide part  32 .  
      This lower restrictive part  36  here is linearly formed, and allows the hose  14 , guided in sliding contact with the lower restrictive part  36 , to move in the lateral direction and the hose  14  to be wound around the whole area of the drum  15  in a distributed way. This enables disorderly winding at the start of winding to be prevented.  
      And from the time a prescribed quantity of the hose  14  has been wound around the drum  15 , the hose  14  can be guided along the upper restrictive part  34  formed by the upper opening edge of the inlet/outlet  33  in the guide part  32 . The above-described effect can be thereby achieved.  
      In this way, by bringing the hose  14  penetrating the inlet/outlet  33  in sliding contact with opening edge of the inlet/outlet  33 , it can be guided to its prescribed position. Therefore, compared with a case in which the hose  14  to be wound around the drum  15  is not guided, disorderly winding of the hose  14  can be prevented, with the result that the appearance of the wound state of the hose can be improved and deviation of the center of gravity due to disorderly winding can be prevented.  
      In this configuration, the thick part  38  thicker than the general part  37  is set for the lower restrictive part  36  constituting the opening edge of the inlet/outlet  33 . For this reason, inadvertent bending of the hose  14  can be more securely prevented than in a case in which the opening edge is composed of a thin part, resulting in improved ease of winding.  
      Furthermore, the section of the thick part  38  of the lower restrictive part  36  is formed in an arc shape, protruding toward the center of the inlet/outlet  33 . As a result, its area of sliding contact with the hose  14  can be reduced, making it possible to restrain the frictional resistance that arises at the time of winding. Therefore, the winding of the hose  14  can be facilitated.  
     Second Embodiment  
       FIG. 10  shows a second embodiment, wherein parts having exact or equivalent counterparts in the above-described embodiment are denoted by respectively the same signs, their description being dispensed with.  
      Thus, a roller  101  as a columnar rotational member is disposed on the lower opening edge of the linearly formed inlet/outlet  33 . The shaft  102  extending from the two ends of this roller  101  is rotatably supported by the bottom  35 , with its ends inserted into the two lower ends of the bottom, and is so configured as to rotate in the direction of urging the movement of the hose  14  when it comes into contact with the hose  14  moving through the inlet/outlet  33 .  
      This enables the hose  14  wound up by the drum  15  to come into contact with the roller  101  disposed on the moving path of the hose  14 . This roller  101  then comes into contact with the hose  14  and rotates in the direction of urging the movement of the hose  14 . The roller  101  is thereby enabled to guide the hose  14  to the drum  15 .  
      Therefore, compared with a case in which the hose  14  to be wound up by the drum  15  is not guided, disorderly winding of the hose  14  can be better prevented and the hose  14  can be wound more neatly. Also, the appearance of the wound state of the hose can be improved, and deviation of the center of gravity due to disorderly winding can be prevented.  
      In this configuration, the roller  101  rotates in the direction of urging the movement of the hose  14 . The resistance of the hose  14  to frictional contact with the roller  101  can be thereby restrained, and the winding of the hose  14  can be facilitated.  
      Incidentally, though this embodiment has been described with reference to a case in which the roller  101  is disposed on the lower opening edge of the inlet/outlet  33 , the choice is not limited to this, but some other rolling members such as another type of roller could give the same effect as described above.  
     Third Embodiment  
      A third embodiment of the invention will be described below with reference to drawings.  FIG. 11  is a drawing showing a hose reel  201  in this embodiment, and the hose reel  201  is used for winding up a hose  202  for sprinkling use.  
      The frame  212  of this hose reel  201  is provided with disk-shaped sides  213  and legs  214  and  214  disposed between the two sides  213 . Between the two sides  213 , a drum  215  for winding up the hose  202  is rotatably supported. The base ends of a handle  216  formed by bending a pipe in an angular C shape is fixed to the two sides  213 , and the hose reel  201  is so configured that it can be carried by this handle  216 .  
      The ends of a guide bar  221  as the guide part for the hose  202  to be wound up by the drum  215  is fixed to the two sides  213 , and the guide bar  221  is formed by bending a pipe in a U shape. This guide bar  221  and the handle  216  are linked by a linking bar  222  to maintain the angle of inclination of the guide bar  221  relative to the handle  216 .  
      The tip of this guide bar  221  is disposed on the moving path of the hose  202  to be wound up by the drum  215 , extends in a direction crossing the moving direction of the hose  202  to be wound up, and constitutes a restrictive part  231  to prevent the hose  202  from escaping. And this restrictive part  231  is formed in an arc shape whose central part protrudes.  
      The drum  215  is configured of a cylindrical barrel  241  around which the hose  202  is wound and collars  242  disposed at the two ends of the barrel  241 , and its ends are rotatably supported in a state of being held between the two sides  213  of the frame  212 .  
      On the other hand, the hose  202  is configured of an inner annular member  251  disposed inside and an outer annular member  252  disposed outside the inner annular member  251  as shown in  FIG. 12 , and a braid  255  consisting of a net portion  253  knit of threads crossing each other diagonally and warps  254 , . . . extending in the lengthwise direction are disposed on the outer circumferential face of the inner annular member  251 . The net portion  253  is configured of first bias threads  256 , . . . and second bias threads  257 , . . . crossing each other.  
      On the outer circumferential face  261  of the outer annular member  252 , convex stripes  262 , . . . and concave grooves  263 , . . . , both extending in the lengthwise direction, are alternately formed to constitute striped convexes and concaves extending in the lengthwise direction.  
      Incidentally, the method of forming convexes and concaves in the outer circumferential face  261  is not limited to this, but the configuration may as well consist of point-shaped convexes for instance.  
      Further, this hose  202  is supposed to be used in all the modes for implementation including the foregoing and those to be described afterwards.  
      In this embodiment pertaining to the above-described configuration, when the hose  202  is wound up by turning the drum  211  with the handle  47 , the hose  202  may sometimes concentrate on one end of the drum  215 , i.e. on the side of one of the collars  242 . However, the guide bar  221  for guiding the hose  202  is disposed on the moving path of the hose  202 , and the central part of the restrictive part  231  disposed on the guide bar  221  has an arch-shaped protruding upward.  
      For this reason, when the hose  202  wound concentrating around an end of the drum  215  reaches a prescribed height, the hose  202  can be guided along the restrictive part  231  in the arch-shaped toward the center.  
      Therefore, disorderly winding of the hose  202  concentrating on one end of the drum  215  can be prevented, and the hose  202  can be wound up neatly. Also, the appearance of the wound state of the hose can be improved, and deviation of the center of gravity can be prevented.  
      And when the hose is wound, the outer circumferential face  261  comes into contact with the inner face of the drum  215  or that of the frame  212  and may give rise to friction. However, as the outer circumferential face  261  of this hose  202  is made rugged in a striped shape by the convex stripes  262 , . . . and the concave grooves  263 , . . . both extending in the lengthwise direction, the frictional resistance to the area of sliding contact can be reduced.  
      Disorderly winding of the hose  202  around the drum  215  can be thereby better prevented than in a case in which high frictional resistance occurs to the area of sliding contact with the hose  202 .  
      Also, the hose  202  can be smoothly wound round the drum  215 , the operational power required for turning the drum  215  can be reduced, and at the same time the winding work can be facilitated.  
      Incidentally, though this embodiment has been described with reference to a case in which the guide bar  221  bridging the sides  213  of the frame  212  is configured of a pipe formed in a U shape, the configuration is not limited to this, but the guide part for guiding the hose  202  to be wound up by the drum  215  may instead be formed of, for instance, a wire rod, wire, pipe or plastic.  
      Further, though this embodiment has been described with reference to a case in which the guide bar  221  and the handle  216  are linked by the linking bar  222 , the configuration is not limited to this, but the linking bar  222  can be dispensed with.  
     Fourth Embodiment  
       FIG. 13  shows a fourth embodiment, wherein parts having exact or equivalent counterparts in the third embodiment are denoted by respectively the same signs, their description being dispensed with.  
      Thus, this hose reel  301  also is of a type in which the drum  215  is exposed, and the frame  212  of the hose reel  301  is formed by bending a single pipe member. A C-shaped leg  214  is formed in the lower part of the frame  212 , and erect portions  302  and  302  stand at the two ends of the leg  214 . Turned-up portions  303  and  303 , turned upward over the leg  214 , are formed continuing from the erect portions  302  and  302 , and supporting portions  304  and  304  rotatably supporting the drum  215  are disposed in the middle parts of the turned-up portions  303  and  303 .  
      The tips of the two turned-up portions  303  and  303  are linked to the guide part  311 , and the restrictive part  231  disposed on the moving path of the hose to be wound up by the drum  215  and extending in a direction crossing the moving direction of the hose to be wound up to prevent the hose from escaping is set on the guide part  311 . And this restrictive part  231  is formed in an arc shape whose central part protrudes.  
      This embodiment can give the same effect as the third embodiment.  
      In addition, since the frame  212  can be configured of a single pipe member, the configuration can be simplified and the cost reduced.  
      Incidentally, though the third and fourth modes for implementation has been described with reference to cases in which the restrictive part  231  is formed in a U shape, the configuration is not limited to this.  
     Fifth Embodiment  
      Thus, as shown in  FIG. 14A , this configuration may be formed of vertical portions  401  and  401  linearly extending upward from the tips of the two turned-up portions  303  and  303 , linear inclined portions  402  and  402  extending inward with an inclination from the tips of the vertical portions  401  and  401 , and a linear linking portion  403  linking the two inclined portions  402  and  402 .  
     Sixth Embodiment  
      Also, as shown in  FIG. 14B , the base ends of the two vertical portions  401  and  401  maybe linked by a linear lateral portion  411  to constitute a lower restrictive part.  
     Seventh Embodiment  
      Further, as shown in  FIG. 14C , with the vertical portions  401  and  401  being abolished, the inclined portions  402  and  402  may be directly linked to the turned-up portions  303  and  303  to configure a trapezoidal restrictive part  231 .  
     Eighth Embodiment  
       FIG. 15  shows an eighth embodiment, wherein parts having exact or equivalent counterparts in the first embodiment described above are denoted by respectively the same signs, their description being dispensed with.  
      Thus, on the moving path of the hose  14  to be wound up by the drum  15 , which is the front face  31  of the upper vessel  13  constituting part of the body case  11 , the guide part  32  for guiding the hose  14  is set. The guide part  32  is provided with the inlet/outlet  33  as the opening through which the hose  14  is to be inserted, and the upper opening edge of the inlet/outlet  33  constitutes the upper restrictive part  34  which obstructs upward escaping of the hose  14 . The upper restrictive part  34  extends in a direction crossing the moving direction I of the hose  14  to be wound up (see  FIG. 1 ), and the upper restrictive part  34  is formed in an angle or trapezoidal shape whose central part protrudes upward.  
      This upper restrictive part  34  is linked to the two ends of the lower restrictive part  36  which the lower edge of the inlet/outlet  33  constitutes, and is configured of inclined parts  501  and  501  inclined toward the central part of the inlet/outlet  33  as they extend upward and a horizontal portion  502  linking the upper ends of the two inclined parts  501 ; the inclination angle β between the horizontally extending lower restrictive part  36  and the inclined parts  501  and  501  is set in a range of not less than 45 degrees and less than 90 degrees.  
      When the hose  14  is wound by turning the drum  15  in the configuration described above, the hose  14  may sometimes concentrate on one end of the drum  15 . However, the guide part  32  for guiding the hose  14  is provided on the moving path of the hose  14 , and the inclined parts  501  and  501  inclined toward the central part as they extend upward are set on the upper restrictive part  34  set on the guide part  32 .  
      As a result, the hose  14  wound concentrating on the end of the drum  15  can be guided toward the center of the inlet/outlet  33  by the inclined parts  501  and  501  when a prescribed quantity has been wound up.  
      Therefore, disorderly winding of the hose  14  concentrating on one end of the drum  15  can be prevented, and the hose  14  can be wound up neatly. Also, the appearance of the wound state of the hose can be improved, and deviation of the center of gravity due to disorderly winding can be prevented.  
      Although a vertical component of force F 1  and a horizontal component of force F 2  then work on the hose  14  in contact with these inclined parts  501  and  501 , but the inclination angle β of the inclined parts  501  is set to be not less than 45 degrees and less than 90 degrees. As a result, the horizontal component of force F 2  is not less than the vertical component of force F 1 , and the force of guiding the hose  14  wound up in the prescribed quantity toward the central part can be kept not less than the force pressing the hose  14  downward.  
      For this reason, it is possible to prevent the hose  14  wound up in the prescribed quantity from being squeezed in a state of being pressed down from above.  
     Ninth Embodiment  
       FIG. 16  shows a hose reel  601  in the ninth embodiment; the hose reel  601  is used for winding up a hose for sprinkling use.  
      This hose reel  601  is provided with a rectangular body case  611  constituting a frame, and the width C 1  of the body case  611  is set to 220 mm. The length C 2  of the body case  611  is set to 375 mm and its height C 3 , to 394.8 mm.  
      This body case  611 , as shown in  FIG. 17 , is formed by a lower vessel  612  as the upward open lower constituent member of an rectangular container and an upper vessel  613 , which is the downward open upper constituent member of the rectangular container, coupled with tapping screws not shown. The internal space K of this body case  611  accommodates a drum  615  around which a hose  614  of 16.4 mm in diameter HD is to be wound as shown in  FIG. 18 .  
      The hose  614  is set to be 2.2 mm in thickness HT and to 12 mm in inner diameter HI. Further, a plurality of convex stripes  620 , . . . extending in the lengthwise direction are formed over the whole length of the outer circumferential face.  
      The drum  615  is configured of a cylindrical barrel  617  around which the hose  614  having penetrated a hose insertion hole  616  is wound and collars  618  and  618  disposed at the two ends of the barrel  617 , and the winding position  619  of the hose  614  is set between the two collars  618  and  618 .  
      This drum  615  is set to a capacity sufficient for winding the hose  614  of 25 m. The length of the hose  614  to be wound up by this drum  615  is set to 80% of it, i.e. 20 m. It is thus designed to be able to wind up the hose  614  at a lower material cost than where a drum of a larger diameter is used. Further by keeping the height C 3  lower, the body case  611  which would not easily fall down is realized.  
      To add, it is desirable for the length of the hose  614  to be wound around the drum  615  to be not greater than 80% of what the drum  615  can accommodate.  
      More specifically, the diameter DD of the collars  618  and  618  is set to 280 mm and the distance H 2  between the two collars  618  and  618 , to 144 mm (see  FIG. 22 ). Thus, the distance H 2  between the two collars  618  and  618  is set to be 40% to 60% of the diameter DD of the collars  618  and  618 , i.e. between 112 mm and 168 mm.  
      While the winding ease of the hose  614  can be enhanced by reducing the distance H 2  between the collars  618  and  618  of the drum  615  herein, too short a distance H 2  between the collars  618  and  618  would make the drum  615  thin and apt to easily fall down. In view of this factor, repeated experiments have led to a discovery that the two requirements can be made consistent with each other by setting the distance H 2  between the collars  618  and  618  of the drum  615  to between 40% and 60% of the diameter DD of the collars  618  and  618 .  
      For this reason, in this embodiment, the distance H 2  between the collars  618  and  618  of the drum  615  is set to 144 mm, which lies between 40% and 60% of the diameter DD of the collars  618  and  618 .  
      Incidentally as another variation, there is made available a configuration in which the distance H 2  between the collars  618  and  618  of this drum  615  is set to 171 mm and the diameter DD of the collars  618  and  618 , to 340 mm, i.e. the distance H 2  between the collars  618  and  618  is set between 40% and 60% of the diameter DD of the collars  618  and  618 . In this drum  615 , the accommodable length of the hose  614  is 38 m, and the length of the hose  614  to be wound around the drum  615  is set to be 30 m, not more than 80% of that accommodable length.  
      The top plate  621  of the upper vessel  613  is formed rectangular and flat as shown in  FIG. 16  and  FIG. 20 . The top plate  621 , set to be large enough to permit the mounting of the body case  611  of another hose reel, constitutes a load carrier.  
      A C-shaped concave  622  is formed in this top plate  621 , and a C-shaped handle  623  is arranged in the concave  622 . The handle  623  is composed of a grip  624  constituting a free end and extension parts  625  and  625  extending from the two ends of the grip  264  into the C shape, and turnably supported by the upper vessel  613  via rotation shafts  626  and  626  disposed at the tips of the extension parts  625  and  625  as shown in  FIG. 21 . In this way, the handle  623  is so configured as to be turnable between an inclined state  627  in which it is accommodated in the concave  622  and an erect state  628  in which it is erect.  
      These extension parts  625  and  625  of the handle  623  are so configured that its turning is restricted as it comes into contact, in its erect state  628 , with a contact part  629  consisting of the upper edge of the concave  622 , and the contact part  629  is composed of an inclined face which is inclined forward. The handle  623  is so configured that, in this erect state  628 , its turning is restricted at a prescribed angle  6 α beyond 90 degrees, more specifically 109 degrees from the inclined state  627 . By virtue of this arrangement, when the handle  623  in the inclined state  627  is to be shifted to the erect state  628 , after the grip  624  constituting the free end of the handle  623  passes above the center of turning consisting of the rotation shafts  626 , the extension parts  625  and  625  stop in a forward inclined state in contact with the contact part  629 .  
      On the moving path of the hose  614  wound up by the drum  615 , the path being the front face  631  of the upper vessel  613 , a guide part  632  for guiding the hose  614  is disposed as shown in  FIG. 22 . The guide part  632  is provided with an inlet/outlet  633  as an opening through which the hose  614  is inserted, and the inlet/outlet  633  is disposed in the position opposite the winding position  619  set between the two collars  618  and  618  of the drum  615 .  
      The width H 1  of the inlet/outlet  633  is set to be not greater than the distance H 2  from one of the collars  618  of the drum  615  to the other collar  618 . More specifically, the width H 1  at the lower end of the inlet/outlet  633 , its greatest width, is set between 134 mm and 154 mm, preferably should be set not greater than 144 mm, the distance H 2  between the two collars  618  and  618  of the drum  615 , and in this embodiment it is set to be less than 144 mm. The height H 3  of the inlet/outlet  633  in the central part, its greatest height is set to be 100 mm.  
      Incidentally, though the width H 1  of the inlet/outlet  633  is set to be less than the distance H 2  between the two collars  618  and  618  of the drum  615  in this embodiment, the two dimensions may as well be the same.  
      To add, the relationship between the width H 1  of the inlet/outlet  633  and the distance H 2  between the two collars  618  and  618  is not limited to this, but the width H 1  may as well be not greater than the distance H 2 , preferably not less than ⅔ of the distance H 2 .  
      The upper opening edge of this inlet/outlet  633  constitutes an upper restrictive part  634  for obstructing the hose  614  from escaping upward. The upper restrictive part  634  extends in a direction crossing the moving direction  6 I of the hose  614  that is wound up (see  FIG. 1 ), and the upper restrictive part  634  is formed in an arc shape whose central part protrudes upward.  
      The starting point S of the arc shape of the opening edge of the inlet/outlet  633  is set in the position of the height of the lower edge of the inlet/outlet  633  and between the center of rotation DC of the drum  615  and the highest position DS of the collars  618  and  618 . As a result, the width H 1  of the inlet/outlet  633  decreases from the lower edge upward.  
      Incidentally, though the foregoing description referred to a case in which the upper restrictive part  634  is formed by the upper opening edge of the inlet/outlet  633 , but the configuration is not limited to this, but it may as well consist of a long member curved in an arc shape for instance.  
      Also the lower opening edge of the inlet/outlet  633  may be open.  
      A lean-to cover  635  is formed over the whole area of this upper restrictive part  634  as shown in  FIG. 21 , and the lean-to cover  635  protrudes toward outside the body case  611 . The height of the upper restrictive part  634  in its highest position is set to be lower than the highest positions of the collars  618  of the drum  615  supported by the body case  611 , and an allowance  6 Y for winding up the hose is provided between the highest position of the upper restrictive part  634  and the highest positions of the collars  618 .  
      The lower opening edge of the inlet/outlet  633  is linearly formed as shown in  FIG. 22 , and a lower restrictive part  636  to allow the hose  614  to move in the horizontal direction is formed on the moving path of the hose  614 . This causes the inlet/outlet  633  to be formed in a semicircular shape whose arch-shaped part is positioned at the top.  
      The lower restrictive part  636  constituting the opening edge of the inlet/outlet  633  is formed thicker than the general part  637  and constitutes a thick part  638  as shown in  FIG. 21 . The sectional shape of this thick part  638  is formed in an arc shape protruding toward the center of the inlet/outlet  633 , and the configuration is such that the hose  614  moving through the inlet/outlet  633  comes into line contact.  
      At the joints between the lower ends of the left and right sides  641  and  642  of this upper vessel  613  and the upper ends of the left and right sides  643  and  644  of the lower vessel  612 , there are formed bulgy parts  645  and  645  bulging sideways, which constitute a circular form when joined together, as shown in  FIG. 16  and  FIG. 22 , and end parts of the barrel  617 , protruding from the collars  618  and  618  of the drum  615 , are rotatably supported between the bulgy parts  645  and  645  as shown in  FIG. 18 . Round holes  646  and  646  are provided at the centers of these bulgy parts  645  and  645 , and the shaft  648  of a crank-shaped handle  647  for turning the drum  615  is inserted into the round hole  646  of the bulgy part  645  arranged on the left side.  
      Also, a connecting plug  651  for connecting the faucet side hose is inserted into the round hole  646  of the bulgy part  645  arranged on the right side, and one end of a pipe member  652  to be connected to the hose  614  wound around the drum  615  is connected to the connecting plug  651 . This configuration enables running water from the faucet to the pipe member  652  via the connecting plug  651  and to the hose  614  on the sprinkling side, wound around the drum  615 , via the pipe member  652 .  
      On the left and right sides  641 ,  642 ,  643  and  644  of the upper and lower vessels  612  and  613  on which the bulgy parts  645  and  645  are formed, hoop-like parts  655  and  655  extending upward and downward are disposed in the upper and lower positions of the bulgy parts  645  and  645 , which are the positions of supporting the drum  615 , as shown in  FIG. 16 . These hoop-like parts  655  and  655  are formed in a corrugated shape by alternately arranged a plurality of convex stripes  656 , . . . and concave grooves  657 , . . . , both extending upward and downward. These hoop-like parts  655  and  655  are thereby configured to reinforce the planar left and right sides  641 ,  642 ,  643  and  644  and to function as props to support the drum  615 .  
      A rectangular bottom opening  662  is cut in the bottom  661  of the lower vessel  612  as shown in  FIG. 23 , and the body case  611  communicates with outside via this bottom opening  662 .  
      Laterally long leg-fixing members  665  and  665  are screwed on along the edges of the front face side  631  and the rear face side  668  of the bottom  661 . Cross-shaped shafts  666  and  666  protrude in mutually opposite directions at the two ends of the leg fixing members  665  and  665  as shown in  FIG. 24 , and legs  667  and  667  formed in the same shape are rotatably supported by the opposite shafts  666  and  666 .  
      At both ends of these legs  667 , cylindrical parts  671  and  671  to externally fit onto the shafts  666  and  666  to constitute base ends  672 , and top plate parts  673  extending toward the tips are integrally formed with these cylindrical parts  671 . The legs  667  and  667  are so configured as to be able to form as desired by turning around the cylindrical parts  671  and  671  a folded state  674  in which, as shown in  FIG. 25 , the tips of both legs  667  and  667  are arranged underneath the body case  611  and both legs  667  and  667  are arranged underneath the bottom opening  662  or a developed state  675  in which, as shown in  FIG. 16 , the tips of both legs  667  and  667  extend sideways from the body case  611  and are in contact with the bottom  661  of the body case  611  (see  FIG. 24 ) to be restricted in turning.  
      The configuration is such that the erect state of the body case  611  can be thereby stabilized in the developed state  675  and, in the folded state  674 , the bottom opening  662  cut in the bottom  661  can be closed by the legs  667  and  667 .  
      The top plate parts  673  are formed in such lengths that, when one leg  667  is folded ahead of the other leg  667  to constitute the folded state  674  shown in  FIG. 26 , the parts of the two legs  667  and  667  farther out than the base ends  672  and  672  overlap each other on their tip side, and on their rear faces a plurality of the ribs  681 , . . . and flanges  682  and  682  extending from their two side edges are integrally formed. The heights of these flanges  682  and  682  and the ribs  681 , . . . are set to become lower from the base ends  672  toward the tips as shown in  FIG. 24 , and the thickness of each leg  667  is set to become thinner from the base ends  672  pivoting on the body case  611  toward the tip.  
      Further, the thickness of the legs  667  and  667  in their overlapping parts  683 , as shown in  FIG. 25 , is so set that the sum of their thickness counts overlapping each other in the folded state  674  be not greater than the greatest thickness of the legs  667  and  667 , i.e. at the base ends  672 , resulting in a configuration in which the legs  667  and  667  are positioned above the under faces of the leg fixing members  665  in the folded state  674 .  
      And as shown in  FIG. 21 , two ribs  692  and  692  extend from the bottom  661  toward the upper opening on an inner side face  691  of the lower vessel  612  of the body case  611 , and two ribs  694  and  694  also extend from the top plate  621  toward the lower opening on an inner side face  693  of the upper vessel  613  of the body case  611 . Thus, these ribs  692 ,  692 ,  694  and  694  extend in the direction of mold drawing when the vessels  612  and  613  are molded of resin.  
      The height  6 H of the ribs  692 ,  962 ,  694  and  694 , as shown in  FIG. 18 , is set to be not less than the separation distance  6 R from each of the inner side faces  691  and  693  to the collars  618  of the drum  615 , the lengths of the ribs  692 ,  692 ,  694  and  694 , as shown in  FIG. 21 , are so set as to bring their tips close to the collars  618 .  
      In this embodiment pertaining to the configuration described above, the body case  611  as a frame for rotatably supporting the drum  615  of the hose reel  601  is formed in a case shape allowing accommodation of the drum  615 , the inlet/outlet  633  for the hose  614  is disposed in the position in the body case  611  opposite the winding position  619  between the two collars  618  and  618  of the drum  615 , and the hose  614  wound up by the drum  615  moves via this inlet/outlet  633 .  
      And the width H 1  of this inlet/outlet  633  is set to be not greater than the distance H 2  from one collar  618  of the drum  615  to the other collar  618 . As a result, the hose  614  accommodated into the body case  611  via the inlet/outlet  633  can be guided to the position between the two collars  618  and  618  of the drum  615 .  
      Therefore, compared with the conventional case in which the winding direction of the hose  614  is open and the hose  614  is apt to be wound into the gap between the drum  615  and the frame, the winding of the hose  614  into the gap between the drum  615  and the inner face of the body case  611  can be prevented, and the hose  614  can be wound up neatly.  
      Especially, where the body case  611  is formed in a case shape and the hose  614 , if wound into the gap between the drum  615  and the body case  611 , will be difficult to take out as in this embodiment, any problem due to the winding-in can be prevented from arising.  
      Further, the distance H 2  between the two collars  618  and  618  provided at the two ends of the barrel  617  of the drum  615  around which the hose  614  is to be wound is set between 40% and 60% of the diameter DD of the collars  618  and  618 ;  
      when the hose  614  is wound around such a drum  615 , even if the hose  614  is wound concentrating on one of the collars  618 , a collapse will arise within. For this reason, the hose  614  is guided to a position between the two collars  618  and  618  by being wound around this drum  615 . This can prevent the hose  614  from inadvertently coming off the drum  615 .  
      Therefore, compared with the conventional case in which the hose is apt to be wound into the gap between the drum and the frame, the winding of the hose  614  into the gap between the drum  615  and the inner face of the body case  611  can be prevented, and the hose  614  can be wound up neatly. Further, as the hose  614  wound concentrating on one of the collars  618  can be collapsed inward, it can be stabilized at the time of winding.  
      And the setting of the distance H 2  between the collars  618  and  618  of the drum  615  between 40% and 60% of the diameter DD of the collars  618  and  618  facilitates winding of the hose  614  and can make the hose reel  601  difficult to fall down.  
      And when the hose  614  is wound up by the drum  615 , the hose  614  may sometimes concentrate on the collar  618  at one end of the drum  615 . However, the upper opening edge of the inlet/outlet  633  through which the hose  614  moves is set to have a width H which becomes narrower upward, and is formed in an arc shape whose central part protrudes upward.  
      For this reason, the hose  614  wound concentrating on one end of the drum  615 , when wound up to a prescribed quantity, is guided toward the center along the arch-shaped opening edge.  
      Thus, even when the hose  614  is concentrating on the collar  618  at one end of the drum  615 , the hose can be guided toward the center along the arch-shaped opening edge at the time it has been wound up to the prescribed quantity. This can prevent disorderly winding, i.e. winding of the hose  614  concentrating on one end of the drum  615 , and the wound state of the hose  614  can be evened up. Therefore, deviation of the center of gravity due to disorderly winding can be prevented.  
      Furthermore, the starting point S of the arc shape of the opening edge of the inlet/outlet  633  is set between the center of rotation DC of the drum  615  and the highest position DS of the collars  618  and  618 . As a result, the hose  614  wound concentrating on the collar  618  at one end of the drum  615  can be guided toward the center along the arch-shaped opening edge before it reaches the highest position DS of the collars  618  and  618 .  
      Incidentally, though the foregoing description referred to a case in which the starting point S of the arc shape of the opening edge is set on the lower edge of the inlet/outlet  633 , but the configuration is not limited to this, but a linear portion  6101  rising from the lower edge of the inlet/outlet  633  may be disposed and an arch portion  6102  in an arch shape formed from its upper end as shown in  FIG. 26 .  
      In this case, the starting point S on the border between the linear portion  6101  and the arch portion  6102  is set between the center of rotation DC of the drum  615  and the highest position DS of the collars  618  and  618 .  
      Nor is the inlet/outlet  633  is limited to the above-described shape, but may as well be semicircular as shown in  FIG. 27A  or triangular as in  FIG. 27B .  
      Further, where the inlet/outlet  633  is to be triangularly shaped, its two upper sides  6111  and  6111  may be rounded, bent toward the center of the opening, as shown in  FIG. 28A , and the range of rounding could be set between  100 R and  300 R for example.  
      In addition, where the inlet/outlet  633  is to be triangularly shaped, its two upper sides  6121 ,  6121  may be rounded, bent outward from the center of the opening, as shown in  FIG. 28B , and the range of rounding could be set between  100 R and  300 R for example.  
     INDUSTRIAL APPLICABILITY  
      As hitherto described, the hose reel according to Claim  1  of the present invention, even when the hose is wound concentrating on one end of the drum, it can be guided along the guide part, whose width decreases toward its upper portion, toward the central part when a prescribed quantity has been wound up.  
      Therefore, disorderly winding of the hose concentrating on one end of the drum can be prevented, and the hose can be wound neatly. Also, the appearance of the wound state of the hose can be improved and deviation of the center of gravity due to disorderly winding can be prevented.  
      Also the hose reel according to Claim  2  of the invention, even when the hose is wound concentrating on one end of the drum, it can be guided by an inclined part provided in the restrictive part toward the central part when a prescribed quantity has been wound up.  
      Therefore, disorderly winding of the hose concentrating on one end of the drum can be prevented, and the hose can be wound neatly. Also, the appearance of the wound state of the hose can be improved and deviation of the center of gravity due to disorderly winding can be prevented.  
      Then, a downward component of force and a horizontal component of force arise in the hose that has come into contact with this inclined part, and the angle of inclination of the inclined part is set to be not less than 45 degrees and less than 90 degrees. For this reason, the horizontal component of force is not less than the downward component of force, and the force guiding the hose stacked to a prescribed quantity toward the central part is not less than the force pressing the hose downward.  
      Therefore, it is possible to prevent the hose wound up in the prescribed quantity from being squeezed in a state of being pressed down from above.  
      Further, the hose reel according to Claim  3  of the invention, even when the hose is wound concentrating on one end of the drum, it can be guided along an arch-shaped restrictive part toward the central part when a prescribed quantity has been wound up.  
      Therefore, disorderly winding of the hose concentrating on one end of the drum can be prevented, and the hose can be wound neatly. Also, the appearance of the wound state of the hose can be improved and deviation of the center of gravity due to disorderly winding can be prevented.  
      Or in the hose reel according to Claim  4  of the invention, when starting winding of the hose around an empty drum, the hose to be moved can be guided along the lower opening edge of the opening in the guide part. In this arrangement this lower opening edge is linearly formed. As a result, the hose guided by the guide part can be wound around the whole area of the drum in a distributed way, and disorderly winding at the time of starting the winding can be prevented.  
      And when a prescribed quantity of the hose has been wound up around the drum, it is guided along the restrictive part formed by the upper opening edge of the opening in the guide part. This provides a similar effect to what was described above.  
      Further in the hose reel according to Claim  5  of the invention, the drum is supported by the frame, and the guide part can be configured by providing this frame with a bar. This contributes to simplifying the configuration.  
      In addition, in the hose reel according to Claim  6  of the invention, by inserting the hose to be wound up by the drum into the opening of the guide part, the hose can be brought into sliding contact with the opening edge of the opening and thereby guided to its prescribed position.  
      Therefore, compared with a case in which the hose to be wound up by the drum is not guided, disorderly winding of the hose can be better prevented and the hose can be wound more neatly. Also, the appearance of the wound state of the hose can be improved, and deviation of the center of gravity due to disorderly winding can be prevented.  
      In this configuration, the thick part thicker than the general part is set for the opening edge of the opening. For this reason, inadvertent bending of the hose can be more securely prevented than in a case in which the opening edge is composed of a thin part, resulting in improved ease of winding.  
      Moreover, in the hose reel according to Claim  7  of the invention, by inserting the hose to be wound up by the drum into the opening of the guide part, the hose can be brought into sliding contact with the opening edge of the opening and thereby guided to its prescribed position.  
      Therefore, compared with a case in which the hose to be wound up by the drum is not guided, disorderly winding of the hose can be better prevented and the hose can be wound more neatly. Also, the appearance of the wound state of the hose can be improved, and deviation of the center of gravity due to disorderly winding can be prevented.  
      In this configuration, the opening edge of the opening is formed in a sectional shape of an arc shape protruding toward the center of the opening. As a result, the area of contact with the hose in sliding contact can be reduced, and the frictional resistance occurring at the time of winding can be restrained. Therefore, the winding of the hose can be facilitated.  
      Further in the hose reel according to Claim  8  of the invention, the hose to be wound up by the drum can be guided by the rotational member rotating in contact with the hose.  
      Therefore, compared with a case in which the hose to be wound up by the drum is not guided, disorderly winding of the hose can be better prevented and the hose can be wound more neatly. Also, the appearance of the wound state of the hose can be improved, and deviation of the center of gravity due to disorderly winding can be prevented.  
      In this configuration, the roller rotates in the direction of urging the movement of the hose. Accordingly, the resistance of the hose to frictional contact with the roller can be thereby restrained, and the winding of the hose can be facilitated.  
      And in the hose reel according to Claim  9  of the invention, the frictional resistance between the outer circumferential face and the area of sliding contact can be reduced by making the outer circumferential face of the hose rugged. Compared with a case in which a high frictional resistance occurs in the area of sliding contact with the hose, disorderly winding of the hose around the drum can be better prevented.  
      The winding of the hose around the drum is further smoothened, the operational power required for turning the drum can be reduced, and at the same time the winding work can be facilitated.  
      Moreover, in the hose reel according to Claim  10  of the invention, the width of the inlet/outlet provided in the frame is set to be not greater than the distance from one collar of the drum to the other, and the hose accommodated into the frame via the inlet/outlet can be guided to the position between the two collars of the drum.  
      Therefore, compared with the conventional case in which the winding direction of the hose is open and the hose is apt to be wound into the gap between the drum and the frame, the winding of the hose into the gap between the drum and the inner face of the body case can be prevented, and the hose can be wound up neatly.  
      Especially, where the frame is formed in a case shape as in the hose reel according to Claim  11 , if the hose is wound into the gap between the drum and the frame and is difficult to take out, any problem due to the winding-in can be prevented from arising.  
      Moreover, in the hose reels according to Claims  12  and  13 , even if the hose is wound concentrating on one end of the drum, it can be guided along the opening edge of the inlet/outlet or the arch-shaped opening edge toward the center when a prescribed quantity has been wound up.  
      This can prevent disorderly winding, i.e. winding of the hose concentrating on one end of the drum, and enable the wound state of the hose to be evened up.  
      Therefore, deviation of the center of gravity due to disorderly winding can be prevented, and the quantity of hose set at the time of designing can be wound around the drum.  
      Further in the hose reel according to Claim  14 , as the starting point of the arc shape of the opening edge is set between the center of rotation of the drum and the highest position of the collars, the hose concentrating on the collar at one end of the drum can be guided toward the center along the arch-shaped opening edge before it reaches the highest position of the collars.  
      Moreover, in the hose reel according to Claim  15 , as the distance between the collars of the drum is set between 40% and 60% of the diameter of the collars, the hose wound around this drum can be guided between the collars. Therefore any trouble due to the going astray of the hose from the drum can be prevented, resulting in neat winding of the hose.  
      Also, as the hose wound concentrating on one of the collars can be collapsed inward, it can be stabilized at the time of winding. And the setting of the distance between the collars of the drum between 40% and 60% of the diameter of the collars facilitates winding of the hose and can make the hose reel difficult to fall down.
