Description

  The present invention relates to a bed and a board protector for the bed.

  In recent years, the beds used in hospitals and the like are moved relatively frequently, so casters are attached to leg stands that support the frame on which the mattress is placed. In some cases, bumpers are attached to the corners of the frame in order to mitigate the impact when colliding with an indoor wall or other objects and to prevent damage. In addition to the bumpers attached to the corners of the above-mentioned underframe, a rotary bumper is provided on a leg stand or the like that supports the underframe, and the impact at the time of collision is changed by changing the direction of the bed at the time of collision. Some relieve stress and correct the direction of the bed. However, when the fixed bumpers at the corners of the underframe and the rotating bumpers such as the footrests are separately attached as described above, the number of members increases, and the assembly is troublesome. Was not very favorable.

Therefore, Patent Document 1 has a function of both a fixed bumper and a rotating bumper as described above, and is intended to provide a bumper device in a bed or the like that is preferable in appearance. Further, a structure is provided in which a rotating bumper is housed inside the fixed bumper with a part protruding outside the fixed bumper.
Japanese Utility Model Publication No. 2002-209796

  If the structure disclosed in Patent Document 1 is adopted, the shock when the bed collides with the wall surface of the room is absorbed and mitigated by the fixed bumper portion, and the rotating bumper built in the fixed bumper has the wall surface or the like. By rotating in contact with the bed, it is possible to change the direction of the bed and further reduce the impact at the time of collision. Further, the direction of the bed can be corrected along the wall surface by abutting the rotating bumper on the wall surface or the like.

 However, since the bed for nursing care as well as the bed for hospitalization may be in contact with a wheelchair parked adjacently, the bed does not cope with this point. This is because the contact location is mainly the edge of the bedboard, but this location is higher than the corner of the bed on which the fixed bumper and the rotating bumper are located.

  Therefore, the technical problem of the present invention is to prevent such problems from being caused.

The technical means taken to solve the above-mentioned problem is as described in claim 1.
"A plastic protector that is detachably attached to the side of the edge of the bed board via a hook-and-loop fastener."
It is to have constituted.

  In the protector according to claim 1, as described in claim 2, “a pair of protrusions that regulate upper and lower limits of the hook-and-loop fastener are formed on the inner surface, and the protrusions are side edges of the board. It can be detachably fitted to ".

Further, the technical measures taken to solve the above-described problems are as described in claim 2,
“A bed including a headboard or a footboard is characterized in that a resin protector is detachably attached to the side surface of the edge of the headboard and / or the footboard via a surface fastener. ,bed."
It is to have constituted.

    In the bed according to claim 3, as described in claim 4, “a pair of protrusions that regulate upper and lower limits of the hook-and-loop fastener are formed on the inner surface, and the protrusions are the headboard and / or It can be detachably fitted to the side edge of the footboard.

  According to the present invention, the resin board protects the bed board from damage. In addition, even if the protector made of resin is damaged, it can be removed from the side of the edge of the bed board and replaced with a new one, so there is no need to rent it in a damaged state. There is an effect.

  Furthermore, a pair of protrusions that restrict the upper and lower limits of the hook-and-loop fastener are formed on the inner surface of the protector, and these protrusions are detachably fitted to the side edges of the board, so that the protector can be positioned. There is also an effect that it can be performed accurately.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

  In FIG. 1, the electric lift bed 10 is mainly composed of a pair of bases 11, 11, a head board 12 and a foot board 13, a drive mechanism (not shown), and a pair of frames 14, 14. It is provided as a simple member.

 The base 11 includes a leg portion 11b and a support portion 11s. The legs 11b installed on the floor function as a base for the electric lift bed 10. The support portion 11s is provided to extend upward from the leg portion 11b.

 The head board 12 and the foot board 13 are configured to be supported by the base 11 by being attached to the pair of bases 11 and 11 so that the support portion 11s of the base 11 is accommodated therein.

 Further, an elevating mechanism (not shown) is provided inside the head board 12 and the foot board 13, respectively. As this lifting mechanism, for example, a known driving mechanism including a motor, a worm, a worm wheel, or the like can be applied. With this lifting mechanism, the headboard 12 and the footboard 13 are moved up and down with respect to the support portion 11s of the base 11, that is, the headboard 12 and the footboard 13 are moved up and down with respect to the base 11. Thus, the height from the floor surface to the bottom surface to be described later can be adjusted within a predetermined range.

 The elevating mechanism can also be operated independently on the headboard 12 side and the footboard 13 side. For example, by raising and lowering the headboard 12 side higher than the footboard 13 side, A tilting operation can be performed so as to be inclined with respect to the surface.

 The head board 12 and the foot board 13 are connected to each other via a pair of frames 14 and 14. Specifically, the U-shaped brackets provided at the corresponding positions of the head board 12 and the foot board 13 are provided at both ends of the frame 14 provided to extend between the head board 12 and the foot board 13. In this state, pins 12p and 13p for pivotally supporting the frame 14 pass through the brackets 12b and 13b and the end portions of the frame 14 sandwiched between the brackets 12b and 13b. It is inserted. Accordingly, the frame 14 is pivotally supported by the head board 12 and the foot board 13.

 A long hole 14 h extending along the frame 14 is formed on the side of the foot board 13 in the frame 14. The aforementioned pin 13p is inserted into the long hole 14h, so that the frame 14 can move relative to the footboard 13. That is, the frame 14 is configured to be able to expand and contract relative to the footboard 13.

 A plurality of floor boards are provided between the frames 14 and 14, thereby forming the bottom surface of the bed.

 Further, the pair of bases 11 and 11 described above are coupled to each other via a coupling member 15 at the leg portions 11b. For example, a rigid metal rod or the like may be applied as the connecting member 15. The connecting member 15 is for setting the foot board 13 that is allowed to move relative to the frame 14 through the long hole 14h to a functionally appropriate position with respect to the head board 12. Furthermore, since the bases 11 and 11 are firmly connected, the rigidity of the entire bed is improved, which is an effective configuration.

 Next, the operation | movement at the time of the tilt operation | movement in the electrically driven raising / lowering bed 10 of this invention is demonstrated.

 FIG. 3 shows a state where the tilting operation is performed in the electric lift bed 10 of the present invention.

 If the lifting mechanism on the headboard 12 side is operated from the state where the headboard 12 side and the footboard 13 side are at the same height, only the headboard 12 side moves up and down. In this case, the headboard 12 side of the frame 14 rotates downward with respect to the headboard 12 around the pin 12p inserted through the bracket 12b, while the footboard 13 side of the frame 14 is the bracket. It pivots upward with respect to the footboard 13 around the pin 13p inserted through 13b. Here, the frame 14 is pivotally supported by a pin 13p inserted through the bracket 13b of the foot board 13 through the long hole 14h described above, and a relative movement with respect to the foot board 13 is allowed. Yes. Therefore, as described above, the foot board 13 side of the frame 14 rotates upward around the pin 13p inserted through the bracket 13b and is simultaneously pulled to the head board 12 side. Due to the action of the long hole 14 h that enables relative movement with respect to the board 13, the frame 14 looks and contracts relative to the foot board 13. As a result, as the headboard 12 moves up and down, the frame 14 pivotally supported by the headboard 12 and the footboard 13 is gradually inclined between the headboard 12 and the footboard 13. Tilt operation in the lift bed 10 can be realized.

 As described above, according to the electric lift bed 10, the frame 14 is pivotally supported by the headboard 12 and is pivotally supported by the footboard 13 through the long hole 14 h extending along the frame 14. It has a configuration. The long hole 14h allows the frame 14 to move relative to the footboard 13. As a result, the frame 14 is configured to be able to expand and contract relative to the footboard 13. Therefore, the frame 14 pivots downward with respect to the headboard 12 on the headboard 12 side as the headboard 12 is moved upward and downward. On the other hand, on the footboard 13 side, it pivots upward with respect to the footboard 13, and at the same time, it looks like it expands and contracts relative to the footboard 13 by the action of the long hole 14h. Tilt operation in the electric lift bed 10 is realized. In the process of this tilting operation, only the positions of the headboard 12 and the frame 14 are changed, and the headboard 12 is lifted up and down straight from the initial installation state with respect to the base 11, and the frame 14 is inclined between the headboard 12 and the footboard 13 by the action of the long hole 14h. Here, paying attention to the installation space of the electric lift bed 10, no extra installation space is required because the positions of the headboard 12 and the frame 14 are changed. Therefore, the electric lift bed 10 that does not require an extra installation space even during the tilting operation can be realized.

  The electric lift bed 10 having the above-described configuration is used as a care bed, and is installed in a hospital room, a nursing facility room, or a general household room. However, in such a room, the wheelchair may be parked along the longitudinal direction of the electric lift bed 10. In this case, when the care recipient operates the wheelchair by himself, the edge of the headboard 12 may be damaged (the same applies to the footboard 13, but only the headboard 12 will be described below). In consideration of such a situation, the following measures are taken.

  As clearly shown in FIG. 3, the headboard 12 includes a main body 121 and resin protectors 130 and 130 attached to both side edges 122 and 122 of the main body 121. Thus, after attaching the protector 130 to the side edge portion 122, one portion 91 of the hook-and-loop fastener fixed to the inner surface of the protector 130 is attached to the other portion 92 of the hook-and-loop fastener fixed to the side edge portion 122. It is made by joining to. Even if a wheelchair contacts the resin protector 130, for example, the side edge 122 is protected. Even if such contact is repeated, only the protector 130 made of resin is damaged. The resin protector 130 can be removed from the side edge 122 of the headboard 12 and replaced with a new one.

  The internal protrusions 131 and 131 of the resin protector 130 are fitted into the holes 123 and 123 of the side edge 122. This is for accurately positioning and can be omitted depending on the case.

It is a figure which shows the state in which the normal raising / lowering operation | movement was performed in the electrically driven raising / lowering bed to which the protector of this invention is applied. It is a figure which shows a state when the electric raising / lowering bed of FIG. 1 performs tilt operation. It is a figure explaining the protector of this invention.
