Description

  The present invention is for a side fence that is attached so as to narrow a gap between a headboard and footboard of a bed and a side fence and between a plurality of side fences, and prevents a limb, a neck, or the like from being caught in the gap. It relates to a spacer.

  2. Description of the Related Art Conventionally, a side fence (also referred to as a side rail) is installed on a side frame of a medical or nursing bed to prevent a user on the bed from falling from the bed. FIG. 11 is a diagram illustrating a bed provided with a conventional side fence as an example. In the bed 2 shown in FIG. 11, a headboard 21 and a footboard 22 are fixed to the ends on the head side and the foot side in the longitudinal direction of the frame 20, and the sides on both sides of the frame 20 are fixed. Each frame is provided with a split-type side fence 23. In the bed 2 in which the split-type side fence is installed, as shown in FIG. 11, the area A between the headboard 21 and the head-side side fence 23, the area B between the side fences 23, and the legs A gap is formed in a region C between the side fence 23 on the part side and the footboard 22.

  In the conventional bed with side rails as shown in FIG. 11, the gaps between the areas A to C formed by the boards 21 and 22 and the side rails 23 are larger than the thickness of the wrist, ankle and neck of a person. It is large and it is easy for a bed user or the like to insert a limb or neck into this gap. Recently, as a bed for medical use and nursing care, for example, a bed in which a bottom on which a bed user lies can be tilted with respect to the frame 20 has been used. If the bed user or the like operates the bed such as raising his back with the limbs or neck inserted in the gaps C to C, the limbs or neck may be pinched. Further, when the bed user loses his / her balance on the bed with his back raised, the limbs or the neck may be caught in the gaps in the areas A to C.

  For example, in Patent Documents 1 to 4, the applicant of the present application has proposed a technique for preventing the limbs, the neck, and the like from being caught in the gap formed by the board and the side fence as described above. For example, in Patent Documents 1 and 2, the applicant of the present application has proposed a connector for connecting the side rails in order to fill a gap formed between the side rails (such as region B in FIG. 11). However, when the side rails are connected to each other by a connecting tool, for example, when the side rails are removable, the connecting tool is once removed from the side rail and then removed from the bed, or connected by the connecting tool. In this state, it is necessary to remove a plurality of fences from the bed at a time, and handling is complicated.

  In addition, in the patent document 3, the applicant of the present application has proposed an auxiliary tool that is attached to the corner portion at the upper end of the side fence on the board side. And the technique which prevents a limb etc. entering easily into the clearance gap part by covering the corner part of the upper end of a side fence with an auxiliary tool with a small curvature radius was proposed.

  Furthermore, the applicant of the present application disclosed in Patent Document 4 a gap formed between the boards 21 and 22 and the side fence 23 by covering the upper part of the side fence with a flexible member made of, for example, a foamed resin plate. A technique of covering with soft material was proposed.

  As a technique for preventing the limbs from being caught in the gap formed by the board and the side fence, in addition to the techniques as described in Patent Documents 1 to 4, recently, an electric nursing bed for home use and a hospital bed are used. JIS standards (Non-Patent Documents 1 and 2) regarding safety of the vehicle have been revised, and attempts have been made to ensure safety by the dimensions and shape of the side rails.

JP-A-10-24071 JP 2003-79664 A JP 2005-152057 A JP 2004-208810 A

JIS T9205 (standard name: hospital bed), established on June 1, 1983, revised on March 20, 2009 JIS T9254 (standard name: electric nursing bed for home use), established on November 21, 2005, revised on March 20, 2009

  However, the above-described conventional technology has the following problems. The assisting tool of the above-mentioned patent document 3 reduces the radius of curvature of the corner portion at the upper end of the side fence to prevent the limbs from slipping into the gap between the boards 21 and 22 and the side fence 23. Even when it is adopted, the gaps between the areas A to C as shown in FIG. 11 cannot be reduced. Moreover, the technique of patent document 4 is that the member which covers a clearance gap is formed with soft materials, such as foamed resin. Therefore, even when the techniques of Patent Documents 3 and 4 are adopted, it is difficult to completely prevent the limbs, the neck, and the like from being caught in the gap.

  The beds and side rails sold recently are designed to satisfy the revised JIS standard, and the gap formed between the boards 21 and 22 and the side rails 23 is designed to be smaller than before. However, there are many beds and side fences designed according to the JIS standard before the revision, and many beds and side fences before the JIS standard was established, and they are still used today. ing. Replacing these old beds and side fences with those that satisfy the revised JIS standard is very costly and time consuming for the user. Therefore, it is desired to develop a technique for satisfying the revised JIS standard in the old bed and side fence.

  This invention is made | formed in view of this problem, Comprising: It aims at providing the spacer for side fences which are easily attached to the conventional side fence, and are easy to handle after attachment.

The side fence spacer according to the present invention includes a horizontal frame, a head board and a foot board fixed to the head side and foot side ends of the frame, and the head attached to the side of the frame. In a side fence spacer used for a bed having a board side and a side fence provided with a corner part whose edge is curved at the upper part on the board side and the foot board side, the corner part is sandwiched between the corners on at least one inner surface. A pair of sandwiching portions formed with guides as recesses to which the portions are fitted, and at least one sandwiching portion extending in a direction away from the sandwiching portion and outward of the corner portion. And an extending portion.

  For example, the bed has a plurality of side rails attached to the sides of the frame, and the extended portion of the spacer attached to one of the side rails adjacent to each other and the spacer attached to the other side rail. The gap formed between the fences on both sides is narrowed by the extension part. In this case, for example, in the spacer attached so as to form a pair between the adjacent side rails, both extending portions extend alternately in the thickness direction.

  In the spacer for the side fence described above, for example, the spacer attached to the corner portion on the headboard side of the side fence near the headboard is a gap formed between the side fence and the headboard by the extended portion. Can be configured to narrow. Also, for example, the spacer attached to the footboard-side corner of the side fence near the footboard is configured to narrow the gap formed between the side fence and the footboard by its extension. May be.

  In the side fence spacer described above, for example, the guide is preferably formed on the inner surfaces of both of the pair of sandwiching portions.

  The spacer for the side fence of the present invention can be attached by simply fitting the corner part of the side fence to the guide formed in the holding part and sandwiching the corner part by a pair of holding parts. It is not necessary to change the bed itself to a new one, and it can be easily attached to the existing side fence.

  Moreover, since it is attached to each corner part of the side fence, for example, when the bed has a plurality of side fences and the side fence needs to be removed from the bed, each of the side fences is attached with the spacer attached. It can be removed and its handling is easy.

  The inventors of the present application have studied various techniques for satisfying the revised JIS standard in the conventional bed and side fence, and have developed the side fence spacer of the present invention. That is, even in the combination of various conventional beds and side fences, by attaching the spacer of the present invention to the side fence, the gap formed between the board and the side fence can be narrowed, such as limbs and necks to the gap, etc. Can be prevented from being caught.

  Hereinafter, the side fence spacer according to the embodiment of the present invention will be specifically described with reference to the accompanying drawings. FIG. 1 is a view showing a bed in which a side fence spacer according to the first embodiment of the present invention is attached to the side fence, and FIG. 2A is a plan view showing the side fence spacer according to the first embodiment of the present invention. FIG. 2 (b) is a side view of the same. FIG. 3A to FIG. 3D are plan views showing the side fence spacer according to the first embodiment of the present invention. As shown in FIG. 1, the side fence spacer 1 of the present invention is attached to a conventional bed 2 as shown in FIG. That is, the headboard 21 and the footboard 22 are fixed to the bed 2 at the end portions on the head side and the foot side in the longitudinal direction of the horizontal frame 20. The head board 21 and the foot board 22 are formed, for example, in a flat plate shape, or formed by connecting a plurality of metal or resin pipes, and these are the length of the frame 20. By being fixed to each end of the direction, the user is prevented from falling from the front and back of the bed 2. In addition, a plurality of side rails 23 for preventing falling are installed on the side frames on both sides of the frame 20 to prevent the user from falling from the left and right sides of the bed 2. This side fence 23 is also formed in a flat plate shape, for example, or a plurality of metal or resin pipes are connected to form a gap between the pipes. In the present embodiment, as shown in FIG. 1, two side fences 23 formed by connecting a plurality of pipes are attached to the respective side portions of the frame. Each side fence 23 reinforces the frame part by narrowing the gap between the two support pipes 23a fixed to the frame and serving as a support part, one or more pipes bent into a frame shape, and the center thereof. The fence part main body 23b comprised by the several pipe to do is comprised. And the corner part where the edge curved is formed in the upper part of the fence part main body 23b at the headboard 21 side and the footboard 22 side, respectively.

  In the bed 2 in which such a split-type side fence 23 is installed, as shown in FIG. 11, the area A between the headboard 21 and the head-side side fence 23, and between the adjacent side fences 23. A gap is formed in the region B and the region C between the side fence 23 on the leg side and the foot board 22. As shown in FIG. 1, the side fence spacer 1 of the present invention has corner portions (upper and side parts of the side fences) at the upper part of the plurality of side fences 23 so as to narrow the gaps between these regions A to C. ). That is, as shown in FIG. 1, one side rail 23 on the head side of the bed 2 is provided with one spacer 1 on the upper side of the headboard 21 and the other side rail 23, respectively. One spacer 1 is attached to the other side fence 23 on the side of the leg portion 2 on the upper footboard 22 side and the one side fence 23 side, respectively.

  In this embodiment, as shown in FIG. 1, each side fence spacer 1 covers, for example, a corner part above the side fence 23, that is, an upper part and a side part of the bent pipe of the fence part main body 23b. Thus, it is comprised by the clamping part 1a formed in the substantially right triangle in side view, and the extension part 1b formed so that it might extend in the direction away from the clamping part 1a with respect to the clamping part 1a. Therefore, when the spacer 1 is attached to the side fence 23, the extension 1b causes a gap between the headboard 21 and the side fence 23 (region A in FIG. 11) and between the footboard 22 and the side fence 23. The gaps (region C in FIG. 11) can be narrowed. Further, when the bed 2 has the split-type side rails 23 as in the present embodiment, the gaps (region B in FIG. 11) between the adjacent side rails 23 are narrowed by the extending portions 1b of the spacers 1, respectively. be able to.

  As shown in FIG. 2, each side fence spacer 1 includes, for example, a first part 11 and a second part 12 that are paired so as to sandwich a corner part on the upper part of the side fence 23, and a first part 11 and a second part. It is comprised by the connection part 13 which connects 12 mutually. The first portion 11, the second portion 12 and the connecting portion 13 are integrally formed of a resin such as polypropylene, for example, and as shown in FIG. 3, the boundary between the first portion 11 and the connecting portion 13, and the second portion 12. The boundary between the connecting portion 13 and the connecting portion 13 is configured to be freely foldable by appropriate elasticity and good bendability depending on the material. The first portion 11 and the second portion 12 each have a clamping surface that is parallel to the fall-preventing surface of the side fence body 23 b, and the clamping surfaces face each other when attached to the side fence 23. Each clamping surface has a part of its outer edge portion extending substantially vertically, and the extension surfaces engage with each other to form a part of the side surface of the spacer 1 together with the connecting portion 13. Thereby, the spacer 1 for side fences is comprised by the shell shape as a whole. As shown in FIG. 2, for example, a locking claw 11 d is provided on one extending surface of the first portion 11 or the second portion 12, and a locking hole 11 e that engages with the locking claw 11 d on the other side. The engaging claw 11d and the engaging hole 11e are engaged so that the corner portion of the side fence 23 is wrapped by the clamping part 1a and the spacer 1 is held by the side fence 23. ing.

  In this embodiment, the connection part 13 is provided in the position corresponded to the hypotenuse of the substantially right triangle of the clamping part 1a. That is, the side fence spacer 1 is inserted into the gap inside the bent pipe of the fence body 23b and bent at the boundary portions of the first portion 11, the second portion 12, and the connecting portion 13, respectively. Thus, the corner portion is attached from the inside of the side fence 23 and fixed to the side fence 23.

As shown in FIG. 2B, for example, in both the first portion 11 and the second portion 12, a plurality of partition walls 11c are erected substantially vertically on the inner surfaces of the clamping surfaces facing each other. Yes. The partition wall 11c is provided corresponding to the inner and outer shapes of the corner portion of the side fence 23, and the region between the partition walls 11c serves as a guide portion 11a as a recess for fitting the corner portion of the side fence 23. . Thus, by providing the guide part 11a in both the 1st part 11 and the 2nd part 12, the thickness of the guide 11a can be divided | segmented into the 1st part 11 and the 2nd part 12, FIG. ), The thickness of the spacer 1 can be reduced. Both end portions of the guide portion 11a are opened on the surface of the spacer 1 in a state where the first portion 11 and the second portion are engaged, and the upper portion and the side portion of the side fence 23 are respectively opened in this opening portion. A straight line portion is taken out. In this embodiment, the dimensions of the portion serving as the guide portion 11a shown in FIG. 2 (b), the width D ₁ of the portion where the straight portion of the top and sides are taken out of the side fence 23, for example, constituting the side fences When the diameter of the pipe is 19 mm, it is several mm larger than the diameter, for example, 19 to 21 mm, and the width D ₂ of the portion that holds the corner portion of the side fence 23 is larger than the diameter of the pipe, for example, 30 Thru 35 mm. These margins take into account manufacturing errors caused by pipe bending when the side fence 23 is manufactured.

  As shown in FIGS. 2 and 3, the first portion 11 and the second portion 12 extend from the partition wall 11 c corresponding to the corner portion of the side fence 23 by a length L, and this portion is the above-described extension portion. 1b. The extension length L of the extension portion 1b is, for example, 42 to 52 mm. In the conventional bed 2, the gap in the area A between the headboard 21 and the side fence 23 is, for example, 49 to 53 mm, and the gap in the area C between the footboard 22 and the side fence 23 is, for example, 49. It is thru | or 92 mm, and the clearance gap of the area | region B between the side fences of the bed which has a split-type side fence is 60 to 70 mm, for example. Therefore, this gap can be narrowed by the extending portion 1b. In the present invention, the extension length L of the extension portion 1b sufficient to narrow the gap means that the dimensions of the bed after spacer installation satisfy at least the regulations of JIS T9205 and JIS T9254. Even when a gap remains between the spacer 1 and another member (the spacer 1 installed on the headboard 21, the footboard 22 or the adjacent side fence), for example, the diameter between the gaps. When a cylindrical jig having a rigidity of 60 mm is placed and a force of 50 N is applied to the jig, the condition that the jig does not enter more than 60 mm is satisfied.

  For the side fence spacer 1, for example, those attached between the headboard 21 side, the footboard 22 side, and the side fence can be unified and used in the same shape. That is, in the conventional bed 2, the gap between the side fences 23 may be smaller than the gap between the headboard 21 and the side fence 23 and the gap between the footboard 22 and the side fence 23. However, as shown in FIG. 2A, for example, the extension portion 1b has a recess 11b for preventing the adjacent extension portions 1b from interfering with each other when attached to a bed having a plurality of side rails. Is provided. Therefore, as shown in FIG. 5, the spacers 1 attached so as to form a pair between adjacent side rails are attached in a state where both the extending portions 1 b extend alternately in the thickness direction.

Next, operation | movement of the spacer for side fences of this embodiment is demonstrated. FIG. 4A to FIG. 4C are diagrams showing a process of attaching the side fence spacer according to the first embodiment of the present invention to the side fence. As shown in FIG. 4A, first, the side fence spacer 1 is brought close to the corner of the fence body 23b, and the side fence spacer 1 is inserted into the gap inside the bent pipe of the fence body 23b. To do. Next, as shown in FIG. 2 (b), the corner portion of the side fence 23 is fitted into the guide portion 11 a between the partition walls 11 c formed on the inner surface of the first portion 11 or the second portion 12. At this time, the width D ₁ of the part from which the upper part of the side fence 23 and the straight part of the side part in the guide part 11a are taken out, and the width D ₂ of the part holding the corner part are dimensions in consideration of manufacturing errors of the side fence 23. Therefore, the side fence 23 can be easily fitted to the guide portion 11a, and the spacer 1 is reliably held by the guide portion 11a.

  Next, the boundary part of the 1st part and the 2nd part 12, and the connection part 13 is bent, and the clamping surface of the 1st part 11 and the clamping surface of the 2nd part 12 face each other. Thereby, the surfaces extended substantially perpendicularly from the outer edge part of the clamping surface approach. And the latching claw 11d provided in one side of this extended surface is engaged with the latching hole 11e provided in the other. As a result, as shown in FIG. 4C, the corner portion above the side fence 23 is wrapped between the first portion 11 and the second portion 12, and the spacer 1 sandwiches the corner portion from the inside of the side fence 23. And fixed to the side fence 23.

  When the bed 2 has a plurality of split-type side rails 23, the spacers 1 are attached to both the adjacent side rails 23, and the gaps between the side rails are narrowed by the spacers 1. In the conventional bed 2, the gap between the side fences 23 is larger than the gap between the headboard 21 and the side fence 23 and the gap between the footboard 22 and the side fence 23. , And may be small. Therefore, when the spacers 1 installed on the side board 23 on the headboard 21 side, the footboard 22 side, and the other side fence 23 side are unified in the same shape, the spacers 1 may interfere with each other. However, in this embodiment, the extension part 1b is provided with the recessed part 11b so that adjacent extension parts 1b may not interfere. Therefore, as shown in FIGS. 5A to 5C, the spacer 1 can be used in one type regardless of the size of the gap between the side fences 23, and between adjacent side fences 23. This gap can also be reliably narrowed by the spacer 1.

  As described above, the side fence spacer 1 of the present embodiment can be attached simply by sandwiching the corner portion constituted by the upper part and the side part of the side fence 23, and the side fence can be changed or the bed itself can be changed. Even if it does not change to a new thing, it can be easily attached to the existing side fence 23.

  Further, the side fence spacer 1 of the present embodiment is attached to each of the side fences 23 when the bed 2 has a plurality of split type side fences 23. Therefore, for example, when it is necessary to remove the side fence 23 from the bed 2, each of the side fences 23 can be removed with the spacer 1 attached, and the handling is easy.

  And in the state which attached the spacer 1 to the side fence 23, the extension part 1b of the spacer 1 will be in the state extended only outward by the length L from the side part of the side fence 23. FIG. As described above, the extension length L eliminates the gap between the conventional headboard 21 and the side fence 23, the gap between the footboard 22 and the side fence 23, and the gap between the plurality of side fences. Even when the gap is left between the spacer 1 and another member (the spacer 1 installed on the head board 21, the foot board 22 or the adjacent side fence), the spacer 1 Is configured with a shape and a material such that each dimension of the bed after installation satisfies the conditions defined in JIS T9205 and JIS T9254. Therefore, it is possible to prevent the limbs, the neck, and the like from being caught in the gap formed by the board and the side fence, and sufficiently ensure the safety of the bed.

  In a bed in which the size of the gap between the side fence 23 and the headboard 21 and the gap between the side fence 23 and the footboard 22 are different, the shape of the spacer 1 is either The gap may be slightly larger. In this case, for example, in addition to the side fence spacer 1, the auxiliary spacer 3 as shown in FIG. 1 may be installed on the board on the side where the gap between the head board 21 or the foot board 22 is large.

  Since the side fence spacer 1 of this embodiment is attached so as to be held at the upper part of the side fence 23 and the corner portions of the side parts, for example, the side fences 231 to 233 having different shapes shown in FIG. Even if the height of the side fences is different, if the diameter of the pipe used as the material of the side fences is about the same thickness, it can be attached to any side fence.

  Moreover, in this embodiment, although the connection part 13 is provided in the position corresponded to the hypotenuse of the substantially right-angled triangle of the clamping part 1a, the spacer 1 of such an aspect is the pipe in which the fence part main body 23b was bent. It can be used when a gap is formed inside. In the present invention, the present invention is not limited to this embodiment. For example, the spacer 1 may be constituted by a pair of the first portion 11 and the second portion 12 without providing the connecting portion 13. Further, for example, as shown in FIG. 7A, the connecting portion 13 may be provided at a position corresponding to the upper portion of the corner portion of the side fence body 23b, and as shown in FIG. You may provide in the extension part 1b extended to the clearance gap side. Thereby, when there is no gap for inserting the spacer 1 inside the fence body 23b, for example, when the side fence body 23b is constituted by a plate-like member, the side fence spacer 1 of the present invention is installed. be able to. Moreover, when connecting the 1st part 11 and the 2nd parts 12 by the connection part 13 like this embodiment, it is not necessarily required to form these by integral molding. For example, a member such as a hinge may be installed between the first portion 11 and the second portion 12 and the connecting portion 13, or the hinge itself may be used as the connecting portion 13.

  Furthermore, in the present embodiment, at least one of the first portion 11 and the second portion 12 that form a pair is provided with a guide portion 11a as a recess into which the corner portion of the side fence 23 is fitted. As long as the spacer 1 can be reliably held on the fence 23, the configuration like the guide portion 11a may not be provided.

  Furthermore, in this embodiment, when it is attached to a bed having a plurality of side rails, a recess 11b is provided so that adjacent extending portions 1b do not interfere with each other. As shown in FIG. 5, when the adjacent extending portions 1b do not interfere with each other due to the distance between the side fences 23, the spacer 1 does not need to be provided with the concave portion 11b.

  Furthermore, in the present embodiment, the extending portion 1b is formed in both the first portion 11 and the second portion 12 that make a pair, but the extending portion 1b is formed by the first portion 11 and the second portion 12. What is necessary is just to be formed in either one.

  Next, the side fence spacer according to the second embodiment of the present invention will be described. First, the structure of the side fence spacer according to the second embodiment will be described. FIG. 8A to FIG. 8C are views showing the side fence spacer according to the second embodiment of the present invention for each member, and FIG. 8A is a plate-like member and a guide member. (B) shows a plate-like member, and FIG. 8 (c) shows a bag-like member. In the first embodiment, the side fence spacer 1 is configured to cover the corner portion above the side fence 23, that is, the upper and side portions of the bent pipe of the fence main body 23b. In this embodiment, the side fence spacer 1 covers the gap area of the side fence 23 including the corner portion.

  In the present embodiment, as shown in FIG. 8, the side fence spacer 10 has two plate-like members 101 and some flexibility made of, for example, foamed polyethylene fixed to one of the plate-like members 101. A plurality of resin members 102 and a bag-like member 103 are included.

  The plate-like member 101 is a cardboard plastic plate, for example, and is provided slightly longer than the height of the side portion of the side fence 23. The plurality of resin members 102 fixed to one plate-like member 101 has a groove between the resin members 102 corresponding to the shape of the pipe on the gap side of the side fence 23, Among these, at least the corner portion is configured to be a guide groove 10a. As shown in FIG. 9, the guide groove 10 a is formed so that side portions of a plurality of types of side fences 231 to 233 can be fitted respectively. That is, in the first embodiment, the partition wall 11c serving as the guide portion 11a is formed in both the first portion 11 and the second portion 12, but in this embodiment, the guide as the concave portion is one clamping portion. Is formed.

  In the present embodiment, at least the corner portion of the side fence 23 is fitted by the pair of plate-like members 101 and the resin member 102, and the region on the gap side is sandwiched, as shown in FIG. By covering the outer sides of the plate-like member 101 and the resin member 102 with such a bag-like member 103, the plate-like member 101 and the resin member 102 are configured to hold the state attached to the side fence 23. Also in the present embodiment, the length of the part where the plate-like member 101 extends from the side fence 23 toward the gap, that is, the part that narrows the gap between each member (headboard, footboard, and side fence) of the bed. The length L is the same as in the first embodiment.

  Next, the operation of the side fence spacer of the second embodiment will be described. FIG. 10A and FIG. 10B are diagrams showing a process of attaching the side fence spacer according to the second embodiment of the present invention to the side fence. In the present embodiment, first, the plate-like member 101 on which the resin member 102 is fixed is brought closer to the side fence 23, and as shown in FIG. It fits corresponding to the guide groove 10a formed between the resin members 102. At this time, as shown in FIG. 9, since the guide groove 10a is provided corresponding to the shape of a plurality of types of side fences, the side fences 23 can be easily fitted between the guide grooves 10a, and the guide grooves The plate-like member 101 and the resin member 102 are securely held by the side fence 23 by 10a. In the present embodiment, unlike the case of the first embodiment, the resin member 102 is made of a slightly flexible resin, so that the dimension between the guide grooves 10a is the side fence as in the first embodiment. It is not necessary to consider the manufacturing error of 23, etc., and the side fence can be fitted even in a state of a slight interference fit.

  When the region on the gap side of the side fence 23 is fitted into the guide groove 10a, the other plate-like member 101 covers the guide groove 10a. As a result, the resin member 102 and the side fence 23 are sandwiched between the pair of plate-like members 101 in a state where the side fence 23 is fitted between the guide grooves 10 a of the resin member 102. In this state, as shown in FIG. 10B, the bag-like member 103 is covered from the outside of the plate-like member 101 and the resin member 102. Thereby, the state where the plate-like member 101 and the resin member 102 are attached to the side fence 23 is held by the bag-like member 103.

  The side fence spacer 10 of this embodiment can also be attached simply by sandwiching the gap-side region of the side fence 23 between the plate-like member 101 and the resin member 102 and covering the bag-like member 103. Even if the bed itself is not changed to a new one, it can be easily attached to the existing side fence 23. Moreover, the same effect as 1st Embodiment can be acquired also about another effect.

  In addition, also in this embodiment, when attaching to the bed which has a some side fence similarly to 1st Embodiment, the recessed part for the adjacent extension parts to not interfere can be provided. Specifically, for example, the size of the plate-like member 101 on the side on which the resin member 102 is fixed may be reduced in accordance with the shape of the recess to be installed, and the resin member 102 may be cut out in accordance with the shape of the recess. Thereby, the spacer 1 installed in the headboard 21 side of the side fence 23, the footboard 22 side, and the other side fence 23 side is made into the same shape, without making the spacers 1 interfere with each other as in the first embodiment. Can be unified.

  Further, for example, the side fence spacer 10 of the present embodiment and the spacer 1 of the first embodiment can be properly used depending on the size of each gap of the bed. For example, as shown in FIG. 9, the spacer 10 of the second embodiment is used to narrow the gap between the headboard and footboard and the side fence, and the first embodiment is used to narrow the gap between the side fences. The spacer 1 may be used. Conversely, the spacer 1 of the first embodiment is used to narrow the gap between the headboard and footboard and the side fence, and the spacer 10 of the second embodiment is used to narrow the gap between the side fences. May be.

  In the above-described embodiment, a case has been described in which gaps for inserting limbs, necks, and the like are formed between the headboard and footboard and the side fence, and between the plurality of side fences. For example, when the gap is small in any region or when no gap is formed, the spacer does not have to be installed.
