Description: Technical Field The present invention relates to a crib serving also as a playpen, and more particularly, it relates to a crib serving also as a playpen which can attain safety assurance responsive to the growth of a baby. Background Technique Fig. 5 discloses a typical crib serving also as a playpen. This crib 1 comprises a bed floor member 2, and panels 3a, 3b, 3c and 3d enclosing all peripheral sides of this bed floor member 2. The bed floor member 2 is supported at a height substantially at the centers of the panels 3a, 3b, 3c and 3d. The state shown in Fig. 5 illustrates a form of employment as a baby bed. In order to ease care for a baby, it is desirable to maintain the height of the bed floor member 2 at a high position while lowering the height of the panels projecting upward beyond the bed floor member 2. In case of using the crib 1 as a playpen, on the other hand, it is desirable to raise the height of the panels projecting upward beyond the bed floor member, in consideration of safety for the baby playing in the playpen. In case of the crib 1 shown in Fig. 5, therefore, the bed floor member 2 is removed from the central portions of the panels 3a, 3b, 3c and 3d when the crib is used as a playpen. The removed bed floor member 2 is directly placed on a floor face enclosed with the panels 3a, 3b, 3c and 3d, or held on lowermost end portions of the panels, for example. In this case, the height of the panels projecting upward beyond the bed floor member 2 is raised and the baby is prevented from getting over the panels. In the crib serving also as a playpen shown in Fig. 5, the operation of removing the bed floor member 2 in response to each form of employment is necessary. A mattress or the like is placed on the bed floor member 2 in general, and hence the mattress or the like must also be removed with the bed floor member. Such an operation is troublesome for the mother. The body of a baby gets larger as it grows, while its movement also gets active. In order to use the crib over a long period, it is desirable to change the form of the crib in response to the growth. In this case, it is desired to make assurance of safety responsive to the growth of the baby on the crib. An object of the present invention is to provide a crib serving also as a playpen which can make assurance of safety responsive to the growth of a baby. Another object of the present invention is to make it possible to readily switch a form of employment as a baby bed and a form of employment as a playpen. Still another object of the present invention is to make it possible to switch a form of employment as a baby bed and a form of employment as a playpen without removing a bed floor member. A further object of the present invention is to enable a mother to readily care for a baby in a form of employment as a baby bed, while enabling the baby to safely play in a playpen in a form of employment as the playpen. A further object of the present invention to make it possible to use a crib over a long period. Disclosure of the Invention In a crib according to the present invention, a panel is height-controllably supported by a base support supporting a bed floor member. According to this structure, the height of the panel can be changed. In case of employing the crib as a baby bed, the panel is brought to a low position, in order to enable a mother or the like to readily care for a baby. In this state, the height of the panel projecting upward beyond the bed floor member lowers, whereby the mother can readily care for the baby. In case of employing the crib as a playpen, on the other hand, the panel is brought to a high position. In this state, the height of the panel projecting upward beyond the bed floor member is raised, whereby such dangerousness that the baby playing in the panel gets over the panel. In the aforementioned crib, the form of employment as a baby bed and the form of employment as a playpen are switched by changing the height of the panel. Therefore, a troublesome operation of removing the bed floor member is unnecessary. In order to height-controllably support the panel, the panel is supported by the base support to be slidable along the vertical direction, as one embodiment. In a preferred embodiment, the base support comprises a support frame directly supporting the bed floor member, and a leg member height-controllably supporting the support frame. The panel is height-controllably supported by the support frame. In the crib comprising the height-controllable support frame, the support frame is maintained at the highest position when the crib is used as a baby bed. In this case, the bed floor member is maintained at a high position, whereby such inconvenience that the mother extremely bends down is eliminated. In case of using the crib as a playpen, on the other hand, it is desirable to approach the bed floor member to a floor face, in view of safety. Thus, the support frame is brought to the lowest position. As a preferable embodiment, the leg member includes a first leg frame and a second leg frame, respective upper end portions of which are rotatably coupled with each other. The support frame is supported by intermediate portions of the first leg frame and the second leg frame. The height of the support frame lowers as the angle between the first leg frame and the second leg frame increases. Desirably, the first leg frame and the second leg frame are rendered to be capable of opening up to an angle of 180° and lining up on a straight line. In this state, the height of the support frame most lowers. In another embodiment according to the present invention, the panel comprises a head part panel positioned on a head side, a foot part panel positioned on a foot side, and two side surface panels positioned on both side portions. Among the four panels, at least one side surface panel is supported to be height-controllable with respect to the base support. Preferably, the side surface panels can take the minimum height position easing care for the baby, an intermediate height position suitable as a baby bed, and a maximum height position suitable as a playpen. In the stage of a newborn baby, the baby does not turn in its sleep, and hence there is no problem in safety even if the height of the side surface panels is brought to the lowest position. When the side surface panels are maintained at the lowest position, the mother or the like can readily care for the baby by changing its diaper or the like. In such a stage that the baby grows and turns in its sleep, the side surface panels are brought to the intermediate height position, for preventing the baby from falling out of the bed floor. This intermediate height position is at a height ensuring safety for the baby, giving no oppressive feeling to the baby, and not interrupting view enabling the mother or the like to see the baby. In case of using the crib as a playpen, the side surface panels are brought to the highest position. When the side surface panels are maintained at such a maximum height position, such dangerousness that the baby moving about in the playpen gets over the playpen is avoided. In order to make safety assurance responsive to the growth of the baby, preferably the base support comprises a support frame directly supporting the bed floor member, and a leg member supporting the support frame while separating the same upward from the floor face. When the crib is used as a baby bed, the support frame is held by the leg member on a position upwardly separating from the floor face. When the crib is used as a playpen, on the other hand, the leg member is folded, or removed, so that the support frame is directly in contact with the floor face. In a preferred embodiment, the crib can be used as an extended bed by horizontally laying the foot part panel for enlarging the length of the bed floor and removing the two side surface panels, in order to use the crib over a long period.

Best Mode for Carrying Out the Invention A crib 10 shown in Fig. 1 and Fig. 2 comprises a panel 12 enclosing all peripheral sides of a bed floor member 13, and a base support 20 supporting the panel 12. The base support 20 includes a support frame 21 directly supporting the bed floor member 13 from below, a coupling plate 22 fixed to this support frame 21, a first leg frame 26, and a second leg frame 27. As shown in Fig. 2, vertically extending slots 23 are formed in the support frame 21. The panel 12 is height-controllably supported on the support frame 21 by bolts 24 passing through the slots 23 and nuts 25 fitted with these bolts. In the state shown in Fig. 2, the panel 12 is held by the support frame 21 on the lowest position. As to the first leg frame 26 and the second leg frame 27, upper end portions thereof are rotatably coupled with each other through an axis 28. Mounting plates 29a and 29b are fixed to the coupling plate 22. A slot 30 extending substantially in a V shape is formed in the mounting plate 29b. The first leg frame 26 and one mounting plate 29a are rotatably coupled with each other through an axis 31. An axis 32 passing through the slot 30 of the mounting plate 29b is fixed to the second leg frame 27. As clear from the structure shown in Fig. 2, the support frame 21 is height-controllably supported by the first leg frame 26 and the second leg frame 27. As the angle between the first leg frame 26 and the second leg frame 27 increases, the height of the support frame 21 lowers. The angle between the first leg frame 26 and the second leg frame 27 is fixed in the state shown in Fig. 2, whereby the height of the support frame 21 is kept intact. In the state shown in Fig. 2, the crib 10 is used as a form of a baby bed. The panel 12 is supported by the support frame 21 on a low position, and hence the height of the panel 12 projecting upward beyond the bed floor member 13 is relatively low. Further, the support frame 21 is brought to a relatively high position by the first leg frame 26 and the second leg frame 27, and hence the bed floor member 13 is maintained at a high position. Therefore, a mother can readily care for a baby lying on the bed floor member 13. In case of using the crib 10 as a playpen, the angle between the first leg frame 26 and the second leg frame 27 is largely increased first as shown in Fig. 3, for lowering the height of the support frame 21. In the illustrated embodiment, the first leg frame 26 and the second leg frame 27 open up to an angle of 180E and line up on a straight line. For this operation, the axis 32 passing through the mounting plate 29b may be merely moved along the slot 30. The first leg frame 26 and the second leg frame 27 extend on a floor face in the state shown in Fig. 3, whereby the support frame 21 is stably held on a low position. From the state shown in Fig. 3, further, the bolts 24 are loosened for slide-moving the panel 12 upward on the support frame 21. Then, the bolts 24 are fixed in a state shown in Fig. 4. A form shown in Fig. 4 is preferable for employment as a playpen. Since the panel 12 is slide-moved upward, the height of the panel 12 projecting upward beyond the bed floor member 11 is raised. Therefore, such dangerousness that the baby playing in the panel 12 gets over the panel is avoided. Further, the bed floor member 13 is brought to a low position by opening the first leg frame 26 and the second leg frame 27 at 180E, whereby this is desirable in the point of safety, and it is possible to let the baby play in the panel 12 at ease. In the embodiment shown in Fig. 2 to Fig. 4, it is not necessary to remove the bed floor member 13 for switching the crib to the form of employment as a baby bed and the form of employment as a playpen. While the support frame directly supporting the bed floor member has been height-controllably supported by the leg member in the illustrated embodiment, the height of the support frame may be fixed. For example, the crib may be used as a baby bed by simply moving the panel 12 downward in the state shown in Fig. 4. Fig. 6 illustrates another embodiment of the present invention. The illustrated crib serving also as a playpen comprises a panel enclosing all peripheral sides of a bed floor member, and a base support 40 supporting the panel. The base support 40 comprises a support frame 41 directly supporting the bed floor member from below, and first and second leg frames 42 and 43 which are fixed to this support frame 41 through screw 57 and 58. The first and second leg frames 42 and 43 have casters 44 and 45 on lower ends thereof. Although not illustrated in Fig. 6, a pair of front frames 47 have a head part panel therebetween. Similarly, a pair of rear frames 48 have a foot part panel therebetween. Side surface panels 46 and 61 (refer to Fig. 6 and Fig. 7) are arranged on both side portions of the crib. In the illustrated embodiment, one side surface panel 46 is height-controllably provided with respect to the base support 40 among the four panels. Concretely, the side surface panel 46 is provided to be vertically slidable between the front frame 47 and the rear frame 48. The side surface panel 46 comprises lock pins 49 and 50. These lock pins 49 and 50 engage in any ones of holes 51, 52, 53, 54, 55 and 56 formed on the front frame 47 and the rear frame 48, so that the side surface panel 46 is fixed and held on three stages of height positions. The first leg frame 42 and the second leg frame 43 can be separated from the support frame 41 by removing the screws 57 and 58. In this case, the removed first and second leg frames 42 and 43 may be stored in the support frame 41 to be fixed and held, as shown by phantom lines in Fig. 6. The rear frame 48 is fixed to the support frame 41 through screws 59 and 60. When the screw 60 is removed and the screw 59 is loosened, the rear frame 48 can rotate about the screw 59. When the rear frame 48 is laid to enter a horizontal state as shown by phantom lines in Fig. 6, the length of the bed floor member can be extended. The crib shown in Fig. 6 is changed to various forms in response to the grow process of a baby. Fig. 7 shows a form of the crib suitable for a stage of a newborn baby. The support frame 41 is supported by the first and second leg frames 42 and 43 to separate upward from a floor face. One side surface panel 46 is brought to a minimum height position. The newborn baby does not turn in its sleep, and hence there is no particular problem in safety even if the side surface panel 46 is brought to the minimum height position. The support frame 41 is maintained at a high position by the first and second leg frames 42 and 43 while the side surface panel 46 is brought to the minimum height position, whereby the mother or the like can readily care for the baby. Fig. 8 shows a form of the crib which is suitable for such a case that the baby grows and its movement becomes active. The side surface panel 46 is brought to an intermediate height position. This intermediate height position of the side surface panel 46 is at a height for preventing the baby who is laid in the crib from falling out of the crib even if it moves actively. Considering only safety, it is desirable to maintain the height of the side surface panel 46 at a high position. However, it is not much preferable to bring the side surface panel 46 to a high position beyond necessity, since this gives an oppressive feeling to the baby and interrupts the view of the mother or the like to the baby. From such a viewpoint, it is desirable to fix and hold the side surface panel 46 on the intermediate height position. Even if the crib is in the form shown in Fig. 8, an operation of the mother or the like is eased when the side surface panel 46 is brought to the minimum height position at the time of caring for the baby. Fig. 9 illustrates a form suitable as a playpen. The first and second leg frames 42 and 43 are folded to be fixed and held in the support frame 41. Therefore, the support frame 41 directly comes into contact with the floor face. In other words, the bed floor member comes to a position approaching the floor face, safety for the baby playing on this bed floor member is increased. The side surface panel 46 is brought to a maximum height position. Thus, such dangerousness that the baby playing in the playpen gets over the side surface panel 46 is avoided. Fig. 10 illustrates a form used as an extended bed following further growth of the baby. The first and second leg frames 42 and 43 are folded to be stored, fixed and held in the support frame 41. The two side surface panels 46 and 61 are removed, and the foot part panel is laid along with the rear frame 48 until the same enters a horizontal state. A forward end portion of the rear frame 48 is maintained by an auxiliary leg member 62 mounted through screws 63 to separate upward from the floor face. Thus, the length of the bed floor member is extended by utilizing the foot part panel which is laid in the horizontal state. The first and second leg frames are folded in this state, whereby the height of the bed floor member is maintained low. Therefore, no serious injury results even if a child lying on the extended bed falls out of the bed floor. While the present invention has been described in relation to the illustrated embodiments, various amendments and modifications are possible in the uniform range of the present invention. For example, the first and second leg frames 42 and 43 have been folded in the aforementioned embodiment, in case of using the crib as a playpen. If safety is confirmed, however, the crib may be used as a playpen in the state standing the first and second leg frames 42 and 43. In such an embodiment, a form suitable as a baby bed and a form suitable as a playpen can be switched by simply moving one side surface panel up and down. When only one side surface panel 46 is removed in the state shown in Fig. 6 or the state shown in Fig. 9, the crib can be used as a sofa. Industrial Availability The structure according to the present invention can be advantageously applied to a crib serving also as a playpen, and a crib which can be used also as an extended bed.
