Description

[Technical field]

[0001] The present invention relates to a bed to which side rails can be attached. [Background technology]

[0002] 2. Description of the Related Art Conventionally, beds are provided with detachable side rails on the front, rear, left and right sides of a bed frame for purposes such as fall prevention and decoration.

[0003] In conventional beds, supports are attached at intervals to the front, back, left and right sides of the bed frame, and each support supports each of the pillars attached at intervals to the side rails, allowing the side rails to be attached freely and detachably to the front, back and left and right sides of the bed (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2006-55529 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the above-mentioned conventional bed, since the support body is fixed to the bed frame, when the bed is used with the side rails removed, the support body protrudes from the bed frame.

[0006] As a result, when a person lying on the bed gets on or off the bed, or when approaching the bed in a wheelchair, etc., there is a risk that the support that protrudes from the bed frame and is fixed may come into contact with the body of the person lying on the bed, the nurse or caregiver, or the wheelchair, etc. [Means for solving the problem]

[0007] In the present invention according to claim 1, supports are provided at intervals on the bed, and each support supports each of the posts provided at intervals on the side rails, so that side rails can be attached to the front, back, left and right of the bed. The supports are fixed to the base of the bed and have movable holders formed with support parts for supporting the posts of the side rails, which are slidably mounted on the fixed holder. The movable holder is slidably movable around one of the posts of the side fence in a direction intersecting the rotation direction of the other post. I decided to do that.

[0009] Also, Claim 2 In the present invention, Claim 1 In the present invention, the support member includes a roller provided between a fixed holder and a movable holder.

[0010] Also, Claim 3 In the present invention, Claim 2 In the present invention, the rollers are arranged above and below the movable holder.

[0011] Also, Claim 4 In the present invention, the above-mentioned claims 1 to Claim 3 In any one of the above aspects of the present invention, the support member is provided with a stopper that prevents the movable holder from sliding when the movable holder is housed in the fixed holder. Effect of the Invention

[0012] The present invention provides the following advantages.

[0013] In other words, in the present invention, in a bed in which supports are provided at intervals on the bed and each support supports each of the pillars provided at intervals on the side rails, allowing side rails to be attached to the front, back, left and right of the bed, the supports are provided with a movable holder that is slidably mounted on a fixed holder fixed to the base of the bed, and has support parts that support the pillars of the side rails.Therefore, when the side rails are not in use, the movable holder of the support can be stored in the fixed holder, preventing contact between the support (movable holder) and the user or objects, thereby improving the safety of the bed.

[0014] In particular, if the movable holder of the support body is made slidable around one of the side pillars in a direction intersecting the rotational direction of the other pillar, the movable holder can be prevented from inadvertently sliding even if a load is applied to the side fence when attaching or detaching the side fence or when the user gets on or off the bed, thereby further improving the safety of the bed.

[0015] Furthermore, when rollers are provided between the fixed holder of the support and the movable holder, the movable holder can be smoothly slid and moved.

[0016] Furthermore, if the rollers are arranged above and below the movable holder, the movable holder can be held so that it can slide from both the top and bottom sides, allowing the movable holder to slide even more smoothly.

[0017] Furthermore, if a stopper is provided to prevent the movable holder from sliding when it is housed in the fixed holder of the support, it is possible to prevent the movable holder from sliding inadvertently when transporting the bed, etc. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] Hereinafter, a specific configuration of the bed according to the present invention will be described with reference to the drawings.

[0020] As shown in Fig. 1, bed 1 has a support 2 for supporting the body of a person lying down, attached to a base 3. For the sake of convenience, the foot side of a person lying down on bed 1 will be described as the front side, and the head side as the rear side.

[0021] The base 3 has legs 4, 4 arranged at intervals in the front and rear directions, and a bed frame 5 having a substantially rectangular frame shape attached to the upper part of the legs 4, 4.

[0022] Supports 6, 7 are attached to the front end of the bed frame 5 at a distance from each other on the left and right. Side rails (footboards 10) each having vertically extending supports 8, 9 at a distance from each other on the left and right are detachably attached to the supports 6, 7.

[0023] Supports 11, 12 are attached to the rear end of the bed frame 5 at a distance from each other on the left and right. Side rails (headboard 15) each having support posts 13, 14 extending vertically and at a distance from each other on the left and right are removably attached to the supports 11, 12.

[0024] Furthermore, supports 16, 17, 18 are attached to the left and right sides of the bed frame 5 with a space between them in the front and rear. A side fence 21 having vertically extending pillars 19, 20 with a space between them is detachably attached to the supports 16, 17, 18. Here, the supports 16, 18 are formed with vertical through-hole-shaped support parts 22, 23 with a space between them in the front and rear, into which the pillars 19, 20 of the side fence 21 are inserted and supported. The support 17 is also formed with a vertical through-hole-shaped support part 24 into which the pillars 19, 20 of the side fence 21 are inserted and supported. The side fence 21 can be attached by inserting the posts 19, 20 of the side fence 21 into the support parts 22, 23 formed on the support body 16 and the support body 18, the side fence 21 can be attached by inserting the posts 19, 20 of the side fence 21 into the rear support part 23 of the front support body 16 and the support part 24 of the central support body 17, and the side fence 21 can be attached by inserting the posts 19, 20 of the side fence 21 into the support part 24 of the central support body 17 and the front support part 22 of the rear support body 18.

[0025] As shown in Figures 1 and 2, the central support 17 is composed of a fixed holder 25 fixed to the bed frame 5 and a movable holder 26 that can slide linearly in a predetermined direction relative to the fixed holder 25, and a support part 24 is formed in the movable holder 26.

[0026] When the movable holder 26 of the support 17 is advanced and protruded relative to the fixed holder 25 (as shown by the dotted line in Figure 2), the support portion 24 of the movable holder 26 moves to a position (use position) that protrudes further from the side of the receiving base 2 in a plan view, so that the support portions 19, 20 of the side fence 21 can be supported together with the rear support portion 23 of the front support 16 (the same applies to the front support portion 22 of the rear support 18).

[0027] In addition, when the movable holder 26 is removed from the fixed holder 25 and stored in the fixed holder 25 (the state shown by the solid line in Figure 2), the support body 17 moves to a position (stored position) in which the movable holder 26 is stored below the receiving base 2 in a planar view, so that the fixed holder 25 and movable holder 26 of the support body 17 do not protrude beyond the side of the receiving base 2.

[0028] This prevents the bodies of the lying person, the caregiver, etc., wheelchairs, movable shelves, etc., from coming into contact with the movable holder 26 of the support body 17 when the lying person gets on and off the receiving platform 2, or when a caregiver or nurse is caring for the lying person, etc., and approaches the bed 1.

[0029] Furthermore, the support 17 is attached to the bed frame 5 extending in front and behind the base 3 with the fixed holder 25 inclined diagonally forward rather than in the perpendicular direction, so that the movable holder 26 slides diagonally forward. That is, when the support 17 supports the posts 19, 20 of the side fence 21 with the rear support part 23 of the front support 16 (similar to the front support part 22 of the rear support 18), the movable holder 26 slides in a direction V2 that intersects with the rotation direction V1 of the other post 20 of the side fence 21 around one post 19 of the side fence 21 (in FIG. 2, the tangent direction of a circular arc with the support part 23 as the center and the distance between the support parts 23 and 24 as the radius R. A direction perpendicular to the base 3 (bed frame 5)).

[0030] As a result, even if a load is applied in a direction pressing the side fence 21 from the outside to the inside of the bed 1 (direction indicated by V1 in Figure 2) when attaching or removing the side fence 21, when a lying person gets on or off the receiving platform 2, or when a caregiver or nurse is caring for a lying person, the load intersects with the direction in which the movable holder 26 slides (direction indicated by V2 in Figure 2), so the movable holder 26 can be prevented from sliding unintentionally.

[0031] The support body 17 may be configured so that a movable holder 26 having a support portion 24 for supporting the pillars 19, 20 of the side rails 21 is slidably mounted on a fixed holder 25 fixed to the base 3 of the bed 1. Specific examples 1 and 2 are shown below.

[0032] [Example 1] As shown in FIGS. 3 and 4, the support 27 according to the first embodiment includes a fixed holder 28 and a movable holder 29 that is slidably movable in a horizontal linear manner.

[0033] The fixed holder 28 has a horizontally long, hollow rectangular box shape with left and right side walls 30, 31 and upper and lower side walls 32, 33, and is open at the front and rear ends. Horizontal rotating shafts 34, 35 are attached between the front ends of the left and right side walls 30, 31, and rollers 36, 37 are attached to the rotating shafts 34, 35 so as to be able to rotate freely.

[0034] The movable holder 29 has a cylindrical support part 39 that is attached to the front end of a slider 38 that extends forward and backward and that penetrates vertically, and the support part 39 is covered with a cover 40. The slider 38 has rollers 36, 37 slidably abutted on the upper and lower parts, and is adapted to slide forward and backward between the upper and lower rollers 36, 37. Note that the slider 38 may be provided with appropriate means for preventing rattling to the left and right and for preventing it from coming off.

[0035] The movable holder 29 has a cylindrical guide cover 41 attached to the rear end of the slider 38, the guide cover 41 being open downward, and a guide body 42 attached to the inside of the guide cover 41 via a contracting spring 43. The guide body 42 is made up of a cylindrical guide main body 44 and a disk-shaped guide flange body 45 formed at the lower end of the guide main body 44. The guide main body 44 is inserted into a guide hole 46, which is elongated from front to rear and formed in the lower side wall 33 of the fixed holder 28, so that the guide main body 44 moves along the guide hole 46. The guide flange body 45 is made wider than the width of the guide hole 46.

[0036] As a result, when a load is applied upward or downward to the movable holder 29 during sliding movement of the movable holder 29 or during use (when the support portion 39 is supporting the side fence 21), the support body 27 is able to hold the movable holder 29 horizontally using the upper or lower rollers 36, 37 and the guide body 42.

[0037] Further, the support 27 is provided with a stopper 47 for preventing the movable holder 29 from sliding when the movable holder 29 is housed in the fixed holder 28 .

[0038] The stopper 47 has a pair of left and right stopper pieces 48, 49 at the rear end of the movable holder 29 that are elastically deformable to the left and right, while a pair of left and right stopper openings 50, 51 are formed at the rear end of the fixed holder 28, and the tips of the stopper pieces 48, 49 engage with the stopper openings 50, 51 to prevent the movable holder 29 from sliding.

[0039] [Example 2] As shown in FIGS. 5 and 6, a support 52 according to the second embodiment includes a fixed holder 53 and a movable holder 54 that is slidable horizontally and linearly.

[0040] The fixed holder 53 has a horizontally elongated hollow rectangular box shape with left and right side walls 55, 56 and upper and lower side walls 57, 58, and is open at the front and rear ends.

[0041] The movable holder 54 has a horizontally elongated, hollow rectangular box shape with left and right side walls 59, 60 and upper and lower side walls 61, 62, and is open at the front and rear ends. A cylindrical support portion 64 is attached to the front end of a slider 63 that extends forward and backward, and the support portion 64 is covered with a cover 65.

[0042] The movable holder 54 has a pair of front and rear rollers 66, 67 (68, 69) rotatably mounted at a distance from each other in the vertical direction in the hollow portion at the rear end of the slider 63. The rollers 66-69 mounted on the movable holder 54 are slidably abutted against the inside of the upper and lower side walls 57, 58 of the fixed holder 53, so that the slider 63 slides back and forth inside the fixed holder 53. Note that a mechanism for preventing the slider 63 from rattling left and right and for preventing it from coming off may be provided as appropriate.

[0043] The front and rear rollers 66, 67 (68, 69) are attached to the front and rear ends of a base 70 (71) via rotation shafts 72, 73 (74, 75). Tops 78, 79 rotatably supported by support shafts 76, 77 are attached to the center of the upper and lower bases 70, 71 with a spring 80 between them.

[0044] The upper rear rotating shaft 73 and the lower front rotating shaft 74 are supported by round holes 81, 82 of the same diameter as the shaft diameter formed in the left and right side walls 59, 60 of the slider 63, while the upper front rotating shaft 72 and the lower rear rotating shaft 75 as well as the upper and lower support shafts 76, 77 are inserted into long holes 83, 84, 85, 86 which are wider than the shaft diameter and extend vertically and are formed in the left and right side walls 59, 60 of the slider 63 so as to be movable up and down.

[0045] As a result, when a load is applied upward or downward to the movable holder 54, such as when the movable holder 54 slides or is in use (when the support portion 64 is supporting the side fence 21), the roller 66 at the upper front side and the roller 69 at the lower rear side move up and down, and all of the rollers 66 to 69 are kept in contact with the insides of the upper and lower side walls 57, 58 of the fixed holder 53, thereby holding the movable holder 54 horizontally.

[0046] Further, the support body 52 is provided with a stopper 87 for preventing the movable holder 54 from sliding when the movable holder 54 is housed in the fixed holder 53 .

[0047] The stopper 87 has a stopper opening 88 penetrating vertically at the rear end of the lower wall 58 of the fixed holder 53, so that the roller 69 at the lower rear side engages and fits into the stopper opening 88 to prevent the movable holder 54 from sliding. A stopper opening 89 also penetrating vertically is formed at the front end of the upper wall 57 of the fixed holder 53, so that the roller 66 at the upper front side engages and fits into the stopper opening 89 to prevent the movable holder 54 from sliding.

[0048] In the above embodiments 1 and 2, the supports 27, 52 supporting the side rails 21 attached to the left and right sides of the bed 1 have been described, but the present invention can also be applied to the supports 6, 7, 11, 12 supporting the side rails (footboard 10 and headboard 15) attached to the front and rear of the bed 1.

[0049] As described above, the bed 1 has supports 16, 17, and 18 spaced apart, and each support 16, 17, and 18 supports each of the pillars 19, 20 spaced apart on the side rail 21, allowing the side rails 21 to be attached to the front, back, left, and right of the bed 1.

[0050] The support body 17 of the bed 1 is configured so that a movable holder 26 having a support portion 24 for supporting the pillars 19, 20 of the side rails 21 is slidably mounted on a fixed holder 25 fixed to the base 3 of the bed 1.

[0051] Therefore, in the bed 1 configured as described above, the movable holder 26 of the support body 17 can be stored in the fixed holder 25 when the side rail 21 is not in use, thereby preventing contact between the support body 17 (movable holder 26) and the user, objects, etc., thereby improving the safety of the bed 1.

[0052] In addition, the support 17 of the bed 1 is configured so that the movable holder 26 of the support 17 can be slid around one of the pillars 19 of the side rail 21 in a direction intersecting the rotation direction of the other pillar 20.

[0053] Therefore, in the bed 1 configured as described above, even if a load is applied to the side rail 21 when attaching or detaching the side rail 21 or when the user gets on or off, the movable holder 26 can be prevented from inadvertently sliding, thereby further improving the safety of the bed 1.

[0054] Further, the support 27 (52) of the bed 1 is configured such that rollers 36, 37 (66-69) are provided between the fixed holder 28 (53) and the movable holder 29 (54).

[0055] Therefore, in the bed 1 having the above configuration, the movable holder 29 (54) can be smoothly slid.

[0056] Further, the support 27 (52) of the bed 1 is configured such that the rollers 36, 37 (66-69) are disposed above and below the movable holder 29 (54).

[0057] Therefore, in the bed 1 having the above configuration, the movable holder 29 (54) can be held so as to be slidable from both the top and bottom sides, so that the movable holder 29 (54) can be slidably moved even more smoothly.

[0058] Further, the support 27 (52) of the bed 1 is provided with a stopper 47 (87) that prevents the movable holder 29 (54) from sliding when the movable holder 29 (54) is housed in the fixed holder 28 (53).

[0059] Therefore, in the bed 1 having the above configuration, it is possible to prevent the movable holder 29 (54) from accidentally sliding when the bed 1 is being transported, etc. [Explanation of symbols]
