Title: Laundry drying rack

Description:
TECHNICAL FIELD 
     The present invention relates to a laundry hanger, and more particularly, to a laundry hanger having a stand that may be drawn out forward in a sliding manner between legs of the laundry hanger or may be detached from the legs of the laundry hanger so as to put a laundry basket on the stand or to further hang out additional laundry on the stand. 
     BACKGROUND ART 
     Recently, laundry drying is achieved by using a hanger placed indoors or on a balcony. As shown in  FIG. 15 , an existing hanger is largely comprised of a pair of supporting members  11  and a pair of hanger members  12  that may be pivoted on the supporting members  11  so as to hang out laundry to be dried thereon. The supporting members  11  have lower portions supported by a floor, respectively, and upper ends thereof are hingedly connected to the hanger members  12 . Further, in order to control a maximum pivot angle by which the pair of supporting members  11  can be spread in opposite directions, connecting members  13  are connected to central portions of the supporting members  11 . These connecting members  13  are configured to have two half regions that may also be pivoted with respect to each other. 
     The hanger members  12  have hanging elements  14  arranged at an interval to substantially dry the laundry. 
     Further, the pair of hanger members  12  are pivoted upward or downward with respect to the supporting members  11 . Here, to control the pivot angles of the hanger members  12 , upper ends of distance-adjusting members  15  hingedly connected to the supporting members  11  are positioned at the hanging elements  14 . 
     However, since the size of the hanger members  12  is constantly fixed and the interval or length of the hanging elements  14  is also constantly fixed in the existing laundry hanger  10  configured as described above, there are problems in that it is not possible to effectively cope with changes in the kind, size or amount of the laundry, and the amount of the laundry that may be accommodated on the laundry hanger is relatively small in comparison with the external size of the laundry hanger. 
     Moreover, such a laundry hanger  10  and a washing machine (or a washing place) are generally provided at separate spaces, and the laundry that has been washed is put in a laundry basket to be carried to a space in which the laundry hanger  10  has been placed, and is then hung out on the laundry hanger  10 . During this procedure, in order to hang out the laundry, which has been put in the laundry basket placed on the floor, on the laundry hanger  10 , the action for bending and stretching one&#39;s back should be repeated, thereby inducing back pains and discomfort. 
     In addition, when the laundry is hung out on the laundry hanger, a load leans too much on an upper portion of the laundry hanger, causing a problem in that the laundry hanger may be easily fallen down due to an external force (wind pressure or touch). 
     DISCLOSURE 
     Technical Problem 
     Accordingly, the present invention is to solve the aforementioned problems. To this end, an object of the present invention is to provide a laundry hanger in which a stand capable of allowing laundry to be hung out thereon can be slid or detached depending on the kind or amount of laundry, thereby drying more laundry. 
     Another object of the present invention is to provide a laundry hanger in which a laundry basket can be put thereon. 
     A further object of the present invention is to provide a laundry hanger in which the distance between supporting points that are in contact with a floor can be extended as desired, thereby preventing the laundry hanger from being fallen down. 
     Technical Solution 
     The laundry hanger of the present invention includes a supporting means, a hanging means, an angle-adjusting means, a stand means, and a fastening means. The supporting means has a pair of legs and can be collapsed. The hanging means allows laundry to be hung out thereon and has a pair of hanger members pivotably coupled to the supporting means. The angle-adjusting means can adjust pivot angles of the hanger members with respect to the supporting means while supporting the hanger members. The stand means has a rest, which is to be positioned between the pair of legs and allows laundry to be hung out thereon, and a stand leg for supporting the rest. The fastening means fastens the rest to the pair of legs such that the rest can be slid between the legs. 
     Further, in the laundry hanger, the supporting means preferably further includes a pair of pivot brackets spaced apart at a predetermined interval, wherein the pair of legs and the pair of hanger members are pivotably coupled to the pair of pivot brackets. In this case, each of the legs has a pair of supporting frames spaced apart at a predetermined interval with ends of the supporting frames pivotably coupled to the respective pivot brackets, and a fastening bar for connecting the supporting frames such that the fastening means can be fastened to the fastening bar. Each of the hanger members has a wing frame with both ends thereof pivotably connected to the respective pivot brackets, and hanging elements connected to the wing frame so as to allow laundry to be hung out on the hanging elements. 
     Further, in the laundry hanger, the fastening means preferably has a plurality of engagement brackets, wherein each of the engagement brackets has one side pivotably coupled to the fastening bar and the other side coupled to the rest, and at least one of the one side and the other side is coupled in a detachable manner. 
     Further, in the laundry hanger, it is preferable that the rest is foldably hinge-coupled. 
     Alternatively, in the laundry hanger, it is possible that the fastening means has a plurality of engagement brackets, wherein each of the engagement brackets has one side pivotably coupled to the fastening bar and the other side coupled to the rest so as to couple the rest to the fastening bar such that the stand can be slid along the fastening bar. 
     Further, in the laundry hanger, it is preferable that the rest is foldably formed so that it can be folded when the supporting means is collapsed. 
     Alternatively, in the laundry hanger, the fastening means may include a first engagement bracket, and a second engagement bracket. In this case, the first engagement bracket has one side pivotably coupled to the fastening bar and the other side coupled to one side of the rest so as to couple the rest to the fastening bar such that the rest can be slid along the fastening bar. The second engagement bracket has one side engaged with the fastening bar and the other side engaged with the other side of the rest, in order to support the rest such that the rest can be detached from the fastening bar when the rest is pivoted. 
     Further, in the laundry hanger, the angle-adjusting means includes a catching member and a supporting member. The catching member has a plurality of catching grooves formed along the length thereof, wherein the catching member is installed at an upper section of each of the legs. The supporting member may have ends pivotably coupled to the respective hanger member, and the supporting member may have one side seated in the catching grooves to support the hanger member. 
     Alternatively, in the laundry hanger, the angle-adjusting means may include a base member, a pivot member, and a control member. The base member is formed in each of the pivot brackets. The pivot member is coupled to an end of the wing frame and installed to be pivoted with respect to the base member. The control member controls a pivot angle of the pivot member with respect to the base member. 
     In this case, in the laundry hanger, it is preferable that a first fastening hole in the shape of a cylinder is formed in one side surface of the base member, and first protrusions extending along an axial direction of the first fastening hole are formed along an inner peripheral surface of the first fastening hole such that first coupling grooves are formed at a predetermined interval circumferentially on the inner peripheral surface of the first fastening hole. At this time, a second fastening hole in the form of a cylinder is formed in the pivot member, and second coupling grooves are formed in a circumferential direction of the second fastening hole such second protrusions are formed at the same predetermined interval as the first protrusions along an inner peripheral surface of the second fastening hole. Moreover, the control member includes a cylindrical button having third protrusions formed along an outer peripheral surface of the button such that the third protrusions can be slidably inserted into the first coupling grooves and the second coupling grooves, and an elastic spring for restoring the sliding of the button. Thus, the angle-adjusting means allows the pivot member to be pivoted when the button is slid so that the third protrusions are inserted only into the first coupling grooves or the second coupling grooves. 
     Further, in the laundry hanger, it is preferable that the base member of the angle-adjusting means is provided at each of the pair of pivot brackets, and the pivot member and the control member are provided respectively at both ends of the wing frame. At this time, the angle-adjusting means further includes a connection bar for connecting the respective buttons provided at the ends of the wing frame to each other. 
     In addition, in the laundry hanger, the stand means preferably further includes a wheel at a lower portion of each of the stand legs. 
     Advantageous Effects 
     According to the present invention, there is provided a laundry hanger having a stand that may be slid between or detached from legs of a supporting means, so that the stand may protrude outside as desired. 
     This allows a laundry basket to be put on the stand. In this case, a user may pick up the laundry from the laundry basket and hangs out the laundry on the laundry hanger without bending his/her back. 
     Further, in this case, stand legs provided at a lower portion of the stand extend the distance between supporting points that are in contact with a floor, thereby preventing the laundry hanger from being fallen down.

     MODE FOR INVENTION 
       FIGS. 1 to 6  show a laundry hanger according to an embodiment of the present invention. The laundry hanger according to the embodiment of the present invention includes a supporting means  100 , a hanging means  110 , an angle-adjusting means  120 , a stand means  130 , and a fastening means  140 . 
     The supporting means  100  has a pair of legs  101  and a pair of pivot brackets  105 . The pair of pivot brackets  105  are arranged to be spaced apart from each other by a predetermined distance. That is, a first pivot bracket  105   a  and a second pivot bracket  105   b  are arranged to be spaced apart from each other by a predetermined distance back and forth. The pair of legs  101  are arranged on right and left sides of the pivot brackets  105 , respectively, and pivotably coupled to the pivot brackets  105 . That is, a first leg  101   a  is arranged on the left side of the pivot brackets  105  and pivotably coupled to the pivot brackets  105 , and the second leg  101   b  is arranged on the right side of the pivot brackets  105  and pivotably coupled to the pivot brackets  105 . 
     To this end, each of the legs  101  has a pair of supporting frames  102  and a fastening bar  103 . The pair of supporting frames  102  are formed to be spaced apart from each other by a predetermined distance, and ends of the supporting frames  102  are pivotably coupled to the pivot brackets  105 , respectively. That is, one end of a first supporting frame  102   a  is pivotably coupled to the first pivot bracket  105   a,  and one end of a second supporting frame  102   b  is pivotably coupled to the second pivot bracket  105   b.  In this embodiment, the other end of the first supporting frame  102   a  and the other end of the second supporting frame  102   b  are connected to each other. Therefore, in this embodiment, the first supporting frame  102   a  and the second supporting frame  102   b  are connected to each other such that each of the legs is “U”-shaped. The fastening bar  103  serves to mount a rest  131  of the stand means  130 . To this end, the fastening bar  103  connects the pair of supporting frames  102  to each other. That is, one end of the fastening bar  103  is connected to one side of the first supporting frame  102   a,  and the other end of the fastening bar  103  is connected to one side of the second supporting frame  102   b.    
     The hanging means  110  serves to allow laundry to be hung out thereon in order to dry the laundry. To this end, the hanging means  110  has a pair of hanger members  111 . The pair of hanger members  111  are arranged on right and left sides of the pivot brackets  105  and pivotably coupled to the pivot brackets  105 . That is, a first hanger member  111   a  is arranged on the left side of the pivot brackets  105  and pivotably coupled to the pivot brackets  105 , and a second hanger member  111   b  is arranged on the right side of the pivot brackets  105  and pivotably coupled to the pivot brackets  105 . To this end, each of the hanger members  111  has a wing frame  113 , an auxiliary bar  114 , and a hanging element  115 . 
     Both ends of the wing frame  113  are pivotably coupled to the pivot brackets  105 , respectively. The wing frame  113  is in the form of “U” so that one end of the wing frame  113  is pivotably coupled to the first pivot bracket  105   a,  and the other end of the wing frame  113  is pivotably coupled to the second pivot bracket  105   b.  The auxiliary bar  114  is installed between the first pivot bracket  105   a  and the second pivot bracket  105   b.  That is, one end of the auxiliary bar  114  is connected to the first pivot bracket  105   a,  and the other end of the auxiliary bar  114  is connected to the second pivot bracket  105   b.  For the hanging element  115 , a plurality of hanging elements are installed in the hanger member  111 . In this embodiment, each of the hanging elements  115  is installed in the hanger member  111  to run right and left, so that one end of the hanging element  115  is connected to the wing frame  113  and the other end of the hanging element  115  is connected to the auxiliary bar  114 . However, depending on embodiments, each of the hanging elements  115  may be installed back and forth as in a conventional laundry hanger. In this case, the hanging elements  115  are connected to the wing frame  113  so that the auxiliary bar  114  may be omitted. 
     The angle-adjusting means  120  serves to adjust the pivot angles of the hanger members  111 . To this end, the angle-adjusting means  120  has catching members  121  and supporting members  122 . 
     A plurality of catching grooves  121   a  are formed along the length of each of the catching members  121  that is installed at upper section of the supporting frame  102 . Both ends of each of the supporting members  122  are pivotably coupled to the respective wing frame  113 , and one side of the supporting member  122  can be seated in one of the catching grooves  121   a.  Accordingly, when the hanger member  111  is pivoted through a certain angle on upper ends of the supporting frames  102  and the supporting member  122  is then pivoted and fitted into the catching groove  121   a,  the hanger member  111  is spread and supported by the supporting member  122 . 
     The stand means  130  has the rest  131  and stand legs  133 . The rest  131  is positioned between the pair of legs  101 , so that laundry can be hung out on the rest  131  and a laundry basket can also be put on the rest  131 . The rest  131  has connections by means of hinges  131   a  at middle portions of the rest  131  so as to be folded simultaneously when the supporting means  100  is collapsed. In order to hang out laundry, hanging elements  131   b  may be installed in the rest  131 . Alternatively, the rest  131  may be formed of a grid panel  131   c  that can be folded about a central portion thereof, as shown in  FIG. 6 . If the rest  131  is formed of the grid panel  131   c,  smaller laundry such as socks can be dried by simply putting it thereon. 
     The stand legs  133  are installed at the bottom of the rest  131  to support the rest  131 . Each of the stand legs  133  is configured to be in the form of “X” and to be collapsed when the rest  131  is folded while being pivoted on the hinges  131   a.  Furthermore, although not shown in this embodiment, the stand means  130  may further have wheels attached to lower ends of the stand legs. Then, the stand means  130  may be easily slid upon back-and-forth movement thereof. 
     The fastening means  140  allows one side of the rest  131  to be detachably coupled to the first leg  101   a  and also allows the other side of the rest  131  to be detachably coupled to the second leg  101   b.  To this end, the fastening means  140  has a plurality of engagement brackets  141 . In this embodiment, the fastening means  140  has four engagement brackets  141 . One side of each of the engagement brackets  141  is pivotably coupled to the fastening bar  103  of its corresponding leg  101  and the other side of the engagement bracket  141  is detachably coupled to the rest  131 . Thus, the stand means  130  may be slid along the engagement brackets  141  and also detached from the engagement brackets  141 . If the rest  131  is detached from the engagement brackets  141 , the stand means  130  may be used as an additional separate laundry hanger. In this case, additional laundry may be hung out on the rest  131 , or a laundry basket may be put on the rest  131 . If the laundry basket is put on the rest  131 , a user may pick up the laundry from the laundry basket and hangs out the laundry on the hanger members  111  without bending his/her back. Although the one side of the engagement bracket  141  is pivotably coupled to the fastening bar  103  and the other side of the engagement bracket  141  is detachably coupled to the rest  131  in this embodiment, the one side of the engagement bracket  141  may be pivotably coupled to the rest  131  and the other side of the engagement bracket  141  may be detachably coupled to the fastening bar  103 . 
     In this embodiment, the stand means  130  can be detached by means of the fastening means  140 . This enables the stand means  130  to be used as an additional hanger and also allows a laundry basket to be put on the stand means  130  so that a user may hang out laundry on the laundry hanger without bending his/her back. 
     In case of the embodiment shown in  FIGS. 1 to 6 , the fastening means  140  detachably couples the stand means  130  to the fastening bars  103  of the legs  101 . 
     However, the stand means  130  is not necessarily detached from the legs  101 , and a laundry basket may be put on the stand means  130  even if the stand means  130  may be slid only. In this case, the fastening means  140  may be formed as shown in  FIGS. 7 to 9 . The fastening means  140  shown in  FIG. 7  has a plurality of engagement brackets  141 . One side of each of the engagement brackets  141  is pivotably coupled to the fastening bar  103 , and the other side thereof is coupled to the rest  131 . At this time, the engagement bracket  141  is coupled such that the rest  131  may be slid back and forth. Meanwhile, since the rest  131  shown in  FIG. 7  is not detached from the fastening bars  103  of the legs  101 , the stand leg  133  may be formed only at one side of the rest  131 . Further, the stand means  130  may have wheels  135  attached to the lower end of the stand leg  133  for easy sliding of the stand means  130 . 
     The fastening means  140  shown in  FIGS. 8 and 9  has first engagement brackets  143  and second engagement brackets  144 . Since the first engagement brackets  143  are identical to the engagement brackets  141  shown in  FIG. 7 , a detailed description thereof will be omitted. 
     One side of each of the second engagement brackets  144  is engaged with the fastening bar  103  and the other side thereof is engaged with the rest  131 , in order to support the rest  131  while coupling the rest  131  to the fastening bar  103  such that the rest  131  may be detached from the fastening bar  103  when the rest  131  is pivoted as indicated by the arrow  150 . To this end, in this embodiment, the second engagement brackets  144  consist of a front second engagement bracket  144   a  and a rear second engagement bracket  144   b  that are formed to be different from each other. The front second engagement bracket  144   a  is fixedly coupled to one side of the fastening bar  103  and connected to the rest  131  such that the rest  131  may be slid. Thus, the front second engagement bracket  144   a  supports the rest  131  to enable the rest  131  to be detached when the rest  131  is pivoted in the direction of the arrow  150 . That is, one side of the front second engagement bracket  144   a  is fixedly coupled to the bottom of the fastening bar  103  and the other side thereof supports the bottom of the rest  131 . The rear second engagement bracket  144   b  is fixedly coupled to the rest  131  and supported by and slidably engaged with the fastening bar. That is, one side of the rear second engagement bracket  144   b  is fixedly coupled to a top portion of the rest  131  and the other side of the rear second engagement bracket  144   b  is put on an upper portion of the fastening bar  103  and supported by the fastening bar  103 . 
     Then, the rest  131  may be slid back and forth along the fastening bars  103 . Further, when the rest  131  is pivoted as indicated by the arrow  150 , the supporting means  100  can be collapsed. 
     Meanwhile, in this case, the stand leg  133  is configured to be in the form of “X” with a pin coupling at the intersection and to be connected to the rest  131  such that one side  133   a  of the stand leg  133  in the form of “X” can be slid along the rest  131 . Thus, as shown in  FIG. 9 , when the rest  131  is pivoted in the direction of the arrow  150 , the stand leg  133  is moved in the direction of the arrow  151  and then collapsed. 
       FIGS. 10 to 12  show a laundry hanger according to another embodiment of the present invention. Except for only the angle-adjusting means  120 , the other components in the embodiment shown in  FIGS. 10 to 12  are identical to those in the embodiment shown in  FIG. 1 . Therefore, only the angle-adjusting means  120  will be described. 
     In the embodiment shown in  FIG. 1 , the angle-adjusting means  120  has the catching members  121  and the supporting members  122 . However, the angle-adjusting means  120  in  FIGS. 10 to 12  has a base member  123 , a pivot member  125 , and a control member  127 , instead of the catching members  121  and the supporting members  122 . 
     The base member  123  is integrally formed in the first pivot bracket  105   a,  and consists of a first fastening hole  123   a,  first coupling grooves  123   b,  and first protrusions  123   c.  The first fastening hole  123   a  is formed in the shape of a cylinder in the first pivot bracket  105   a.  The first protrusions  123   c  are embossed along an axial direction of the first fastening hole  123   a  so as to be formed along an inner peripheral surface of the first fastening hole  123   a  such that the first coupling grooves  123   b  are formed at a certain interval circumferentially on the inner peripheral surface of the first fastening hole  123   a.    
     The pivot member  125  is formed at an end of the wing frame  113  of the hanger member  111 , and a second fastening hole  125   a  in the shape of a cylinder is formed in the pivot member  125 . Further, second coupling grooves  125   b,  which are formed to have a predetermined length along an axial direction of the second fastening hole  125   a  such that second protrusions  125   c  are formed at the same interval as the first protrusions  123   c  on an inner peripheral surface of the second fastening hole  125   a,  are engraved circumferentially in the second fastening hole  125   a.  Thus, the sizes of the second coupling grooves  125   b  and second protrusions  125   c  of the pivot member  125  in a circumferential direction are identical to those of the first coupling grooves  123   b  and first protrusions  123   c  of the base member  123 . Here, the second coupling grooves  125   b  are formed to have only the predetermined length along the axial direction of and partially over the depth of the second fastening hole  125   a  of the pivot member  125 . Thus, as shown in  FIG. 11 , the second coupling grooves  125   b  and the second protrusions  125   c  are formed only at a lower portion of the second fastening hole  125   a.    
     The control member  127  serves to rotate or fix the pivot member  125  with respect to the base member  123 . To this end, the control member  127  has a cylindrical button  128  and an elastic spring  129 . The button  128  is inserted to be slid into the first fastening hole  123   a  and the second fastening hole  125   a.  At this time, an outer peripheral surface of the button  128  is formed circumferentially with third protrusions  128   a  that can be inserted into the first coupling grooves  123   b  of the first fastening hole  123   a  and the second coupling grooves  125   b  of the second fastening hole  125   a.  The elastic spring  129  is inserted into the first fastening hole  123   a  of the base member  123  so as to support the button  128 . 
     Accordingly, referring to  FIG. 12(   a ), in an initial state where the button  128  is inserted into the first fastening hole  123   a  and the second fastening hole  125   a,  the third protrusions  128   a  of the button  128  are inserted into both the first coupling grooves  123   b  of the base member  123  and the second coupling grooves  125   b  of the pivot member  125 . In this case, the pivot member  125  is fixed without rotation thereof with respect to the base member  123 . That is, since the third protrusions  128   a  of the button  128  are inserted into the first coupling grooves  123   b  and the second coupling grooves  125   b,  the third protrusions  128   a  serve as a stopper. However, when the button  128  is pressed down as indicated by an arrow  1  in  FIG. 12(   b ), the button  128  is slid in a direction toward the first fastening hole  123   a.  Then, the third protrusions  128   a  of the button  128  are inserted only into the first coupling grooves  123   b  of the base member  123 . In this case, the third protrusions  128   a  serving as a stopper for restraining the pivot member  125  escape from the second coupling grooves  125   b,  so that the pivot member  125  can be freely rotated with respect to the base member  123 . 
     When the pivot member  125  is pivoted and then the button  128  is not pressed down, the button  128  is raised by the elastic spring  129  and returned to the position shown in  FIG. 12(   a ). At this time, the third protrusions  128   a  are inserted again into the first coupling grooves  123   b  and the second coupling grooves  125   b,  thereby restraining the pivot member  125 . Therefore, when the button  128  is pressed down, the pivot member  125  can be freely pivoted, and when the button  128  is not pressed down, the pivot member  125  is fixed. 
     The pivot member  125  is fixed to an end of the wing frame  113  of the hanger member  111 . Thus, when the button  128  of the angle-adjusting means  120  is pressed down, the hanger member  111  can be pivoted. When the button  128  is not pressed down, the hanger member  111  can be fixed. 
     Meanwhile,  FIGS. 13 and 14  show another example of an angle-adjusting means that can be used in a laundry hanger according to the present invention. In the embodiment shown in  FIGS. 10 to 12 , the angle-adjusting means  120  is installed only at one end of the hanger member  111 . In this case, the angle-adjusting means  120  supports only one end of the hanger member  111 .  FIGS. 13 and 14  show an embodiment of the angle-adjusting means  120  that can support both ends of the hanger member  111 . Since a laundry hanger in which the angle-adjusting means shown in  FIG. 13  is installed is identical to the laundry hanger shown in  FIG. 12  in their perspective views, the perspective view thereof will be omitted. 
     The angle-adjusting means  120  shown in  FIG. 13  has a pair of base members  123 , a pair of pivot members  125 , a pair of control members  127 , and a connection bar  126 . 
     Each of the base members  123  is formed with a first fastening hole  123   a,  first coupling grooves  123   b,  and first protrusions  123   c.  Although the first coupling grooves  123   b  and the first protrusions  123   c  in the embodiment shown in  FIG. 10  are formed to have only the predetermined length along the axial direction of and partially over the depth of the first fastening hole  123   a,  the first coupling grooves  123   b  and the first protrusions  123   c  in the embodiment shown in  FIG. 13  are formed up to an end of the first fastening hole  123   a  along the axial direction thereof. A first base member  123 _ 1  of the pair of base members  123  is formed in the first pivot bracket  105   a  and a second base member  123 _ 2  is formed in the second pivot bracket  105   b.    
     Each of the pivot members  125  is formed with a second fastening hole  125   a,  second coupling grooves  125   b,  and second protrusions  125   c.  Although the second fastening hole  125   a  in the embodiment shown in  FIG. 10  is formed to have a predetermined depth in the pivot member  125 , the second fastening hole  125   a  in  FIG. 13  is formed to penetrate therethrough. The second coupling grooves  125   b  and the second protrusions  125   c  are formed along the circumference of the second fastening hole  125   a,  and formed to have only a predetermined length along the axial direction of and partially over the depth of the second fastening hole  125   a.  Thus, it is possible to prevent the button  128  of the control member  127  from escaping outward. A first pivot member  125 _ 1  of the pair of pivot members  125  is formed at one end of the wing frame  113  and coupled to the first base member  123 _ 1 , and a second pivot member  125 _ 2  is formed at the other end of the wing frame  113  and coupled to the second pivot member  125 _ 2 . 
     The control member  127  has a pair of buttons  128 , and a pair of elastic springs  129 . A first button  128 _ 1  of the pair of buttons  128  is inserted into the first base member  123 _ 1  and the first pivot member  125 _ 1 , and a second button  128 _ 2  is inserted into the second base member  123 _ 2  and the second pivot member  125 _ 2 . A first elastic spring  129 _ 1  of the pair of elastic springs  129  is inserted into the first pivot member  125 _ 1  to support the first button  128 _ 1 , and a second elastic spring elastic spring  129 _ 2  is inserted into the second pivot member  125 _ 2  to support the second button  128 _ 2 . 
     The connection bar  126  is inserted into the auxiliary bar  114  and installed between the first pivot bracket  105   a  and the second pivot bracket  105   b.  At this time, the connection bar  126  connects the first button  128 _ 1  and the second button  128 _ 2 . That is, one end of the connection bar  126  is connected to the first button  128 _ 1 , and the other end of thereof is connected to the second button  128 _ 2 . Since the connection bar  126  is inserted into the auxiliary bar  114 , the connection bar  126  is not exposed outside. However, when the hanging elements  115  are installed back and forth and thus the auxiliary bar  114  is not required, the connection bar  126  is exposed outside. 
     In this embodiment, since the first pivot member  125 _ 1  is formed at one end of the wing frame  113  of the hanger member  111  and the second pivot member  125 _ 2  is formed at the other end of the wing frame  113 , both ends of the hanger member  111  are supported by the angle-adjusting means  120 . 
     When no load is applied to the button  128  as shown in  FIG. 14(   a ), the third protrusions  128   a  of the button  128  are inserted into the second coupling grooves  125   b  of the pivot member  125  and the first coupling grooves  123   b  of the base member  123 , thereby fixing the pivot member  125 . However, when the button  128  is pressed down as shown in  FIG. 14(   b ), the first button  128 _ 1  is slid in a direction toward the first pivot member  125 _ 1 . Then, the third protrusions  128   a  of the first button  128 _ 1  escape from the first coupling grooves  123   b  of the first base member  123 _ 1  and are inserted only into the second coupling grooves  125   b  of the first pivot member  125 _ 1 . Thus, the first pivot member  125 _ 1  can be freely pivoted with respect to the first base member  123 _ 1 . Meanwhile, when the first button  128  is moved, the connection bar  126  is moved in the same direction as that of the first button  128 _ 1 , which causes the second button  128 _ 2  to be moved in the same direction as that of the first button  128 _ 1 . Accordingly, the second button  128 _ 2  protrudes from the second base member  123 _ 2 . Then, the third protrusions  128   a  of the second button  128 _ 2  escape from the second coupling grooves  125   b  of the second pivot member  125 _ 2  and are inserted only into the first coupling grooves  123   b  of the second base member  123 _ 2 . Thus, the second pivot member  125 _ 2  is also freely pivoted with respect to the second base member  123 _ 2 . In this case, the hanger member  111  can be pivoted. 
     When the load for pressing the first button  128 _ 1  is removed, the button  128  is returned to the state shown in  FIG. 14(   a ) by a restoring force of the elastic spring  129 . Then, the pivot member  125  is fixed.
