Description

[Technical field]

[0001] The present invention relates to a bed in which a support is provided on the side of a bed frame so as to extend outward from the side of the bed frame, and a side rail is attached to the support portion of the support. [Background technology]

[0002] Conventionally, beds are provided with side rails on the sides of the bed frame to prevent falls, etc.

[0003] In conventional beds, a support extending in the front-to-rear direction is fixed to the side of the bed frame, and support portions for supporting the side rails are formed on the support at intervals in the front-to-rear direction.

[0004] The side rails are configured so that they can be attached to the bed by inserting vertically extending support posts formed at the front and rear of the side rails into the front and rear support parts of the support body (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2006-55529 A Summary of the Invention [Problem to be solved by the invention]

[0006] Because the width of the support platform that supports the body of a person lying down needs to differ depending on the installation location and purpose, multiple types of support platforms with different widths had to be prepared (produced) in advance, and operators also had to select (purchase) a bed that was suitable for the installation location and purpose, etc.

[0007] However, in the conventional beds described above, the side rails are supported by supports fixed to the bed frame, so it is necessary to prepare (produce) multiple types of bed frames with different left and right widths to match the left and right width of the bed, which increases the manufacturing costs of the bed and also increases the management burden on businesses. [Means for solving the problem]

[0008] In the present invention according to claim 1, a support is provided on a side of a bed frame so as to protrude outward from the side of the bed frame, and a side rail is attached to the support part of the support. The support is configured separately into a front support that supports the front side of the side fence and a rear support that supports the rear side of the side fence, and the front support or the rear support has a plurality of supports each having a different protruding amount of the support part, The support is provided on the side of the bed frame in such a manner that the position of the support part of the support can be changed so that the protruding amount of the support part of the support can be in different positions.

[0009] In addition, in the present invention according to claim 2, In a bed in which a support is provided on the side of a bed frame so as to protrude outward from the bed frame, and a side fence is attached to the support part of the support, the support is separated into a front support that supports the front side of the side fence and a rear support that supports the rear side of the side fence, and the front support or the rear support has a support device made up of multiple support pieces with different protruding amounts for each support part, and the support is provided on the side of the bed frame so that its position can be changed so that the protruding amounts of the support parts of the support can be different. I decided to do so.

[0010] In addition, in the present invention according to claim 3, In a bed in which a support is provided on the side of a bed frame so as to protrude outward from the bed frame, and a side fence is attached to the support part of the support, the support is separated into a front support that supports the front side of the side fence and a rear support that supports the rear side of the side fence, and the front support or the rear support has a support tool that can be attached to the bed frame in multiple mounting states with different protruding amounts of the support part, and the support is provided on the side of the bed frame in a position that can be changed so that the protruding amount of the support part of the support is different. I decided to do so. Effect of the Invention

[0011] The present invention provides the following advantages.

[0012] In other words, in the present invention, in a bed in which a support is provided on the side of a bed frame so that it extends out to the side of the bed frame and a side rail is attached to the support part of the support, the support is provided on the side of the bed frame in a position that can be changed so that the amount of extension of the support part of the support can be in different positions.Therefore, even if the left and right widths of the receiving platform that supports the body of a reclining person are different, the side rail can be attached to a common bed frame, which reduces the manufacturing costs of the bed and eases the management burden on the operator.

[0013] In particular, if the support body is separated into a front support body that supports the front side of the side fence and a rear support body that supports the rear side of the side fence, the weight of each front and rear support body can be reduced, thereby reducing the workload when changing positions.

[0014] Furthermore, if the support body has multiple supports with different protrusion amounts for each support part, the amount of protrusion of the side fence can be easily selected visually by using multiple supports in different ways, further reducing the workload when changing positions.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] Hereinafter, a specific configuration of the bed according to the present invention will be described with reference to the drawings.

[0017] 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.

[0018] The support base 2 is composed of a back bottom 4 that supports the back of the lying person, a buttocks bottom 5 that supports the buttocks, an upper leg bottom 6 that supports the upper thighs, and a lower leg bottom 7 that supports the lower leg. The back bottom 4 is tiltably attached to the base 3, the buttocks bottom 5 is fixed to the base 3, the upper leg bottom 6 is tiltably attached to the base 3, and the lower leg bottom 7 is tiltably attached to the upper leg bottom 6, so that the back bottom 4, upper leg bottom 6, and lower leg bottom 7 can be tilted in unison.

[0019] The base 3 has a rectangular bed frame 9 attached to the top of legs 8, 8 spaced apart from each other in the front and rear. A footboard 10 is attached to the front end of the bed frame 9, and a headboard 11 is attached to the rear end of the bed frame 9.

[0020] On the base 3, the support 2 is attached to the top of the bed frame 9, and side rails 12 are provided on the left and right sides of the bed frame 9 at a distance in the front and back. Each side rail 12 has posts 13, 14 extending up and down on the front and rear sides, and each post 13, 14 is supported by two supports 15, 16 attached to the sides of the bed frame 9 at a distance in the front and back.

[0021] [Example 1] As shown in Fig. 2, the supports 15 and 16 according to the first embodiment are provided with a base end of a fixture 17 attached to the bed frame 9, and a plurality of (here, two) supports 18 and 19 are attached to the tip of the fixture 17 so as to be rotatable forward and backward (left and right in Fig. 2) by a rotation shaft 20 extending vertically. The front and rear supports 15 and 16 are symmetrical in the front and rear directions.

[0022] One of the supports 18 has a shape that extends linearly toward the side of the bed frame 9 when viewed in a plane, and has a support portion 21 in the form of an upper and lower through hole at its tip for inserting the lower end of the support pillar 13 (14) of the side rail 12 from above.

[0023] At the front support 15, the support 18 is prevented from rotating forward from a position perpendicular to the bed frame 9 by a stopper piece 22 formed on the front side of the fixing device 17, and at the rear support 16, the support 18 is prevented from rotating rearward from a position perpendicular to the bed frame 9 by a stopper piece 22 formed on the rear side of the fixing device 17.

[0024] The other support device 19 has a shape that extends in an approximately C-shaped bent manner toward the side of the bed frame 9 when viewed in a plane, and the tip device has a support portion 23 in the form of an upper and lower through hole for inserting the lower end of the support pillar 13 (14) of the side fence 12 from above.

[0025] At the front support 15, this support 19 is prevented from rotating forward by one of the supports 18 abutting against the stopper piece 22 of the fixing device 17, and at the rear support 16, this support 19 is prevented from rotating backward by one of the supports 18 abutting against the stopper piece 22 of the fixing device 17.

[0026] The supports 18 (19) provided on the front and rear supports 15, 16 are prevented from rotating, and the distance between the front and rear support parts 21 (21) is maximized, and only in this state can the front and rear posts 13, 14 of the side fence 12 be inserted into the front and rear support parts 21 (21). This allows the side fence 12 to be attached to the bed frame 9 without moving forward or backward.

[0027] When the support devices 18 (19) of the front and rear supports 15, 16 are prevented from rotating and the side rails 12 can be attached, the amount of protrusion W1 (see Figure 3) by which the support portion 21 formed on one support device 18 protrudes toward the side of the bed frame 9 is greater than the amount of protrusion W2 (see Figure 3) by which the support portion 23 formed on the other support device 19 protrudes toward the side of the bed frame 9.

[0028] In this way, by varying the projection amounts W1, W2 of the support portions 21, 23 of multiple (here, two) supports 18, 19 provided on each support 15, 16, the amount by which the side rail 12 projects laterally from the bed frame 9 can be changed when the side rail 12 is attached to each support 15, 16.

[0029] With this support body 15 (16), as shown in Figure 3 (a), one support 18 is abutted against the stopper piece 22, and the other support 19 is abutted against the one support 18, and the side fence 12 is attached to the support portion 23 of the other support 19, so that the side fence 12 can be made to protrude relatively far from the side of the bed frame 9.

[0030] Furthermore, with the support body 15 (16), as shown in Figure 3 (b), one of the supports 18 is abutted against the stopper piece 22, and the other support 19 is rotated toward the bed frame 9, and the side fence 12 is attached to the support portion 21 of the one of the supports 18, so that the side fence 12 can be placed in a state in which it protrudes relatively slightly from the side of the bed frame 9.

[0031] Furthermore, in the support body 15 (16), as shown in FIG. 3(c), both supports 18, 19 can be rotated toward the bed frame 9, thereby allowing both supports 18, 19 to be stored.

[0032] In the above-mentioned embodiment 1, it is sufficient that the side fence 12 is attached to the bed frame 9 without moving back and forth, and for example, the supports 15 and 16 may be attached to the bed frame 9 on the opposite sides, or one of the supports may be fixed, in which case the stopper piece does not need to be formed. Also, it is not limited to the stopper piece 22 as long as the structure can prevent the rotation of the supports 15 and 16. The same applies to the following embodiments 2 and 3.

[0033] [Example 2] In the support according to the first embodiment, a plurality of (here, two) supports are configured to change (rotate) their postures independently, but they may be configured to change their postures integrally.

[0034] As shown in Fig. 4, in the support body 24 according to the second embodiment, the base end of the fixture 25 is attached to the bed frame 9, and the support body 26 is attached to the tip of the fixture 25 so as to be rotatable back and forth (left and right in Fig. 4) by a rotation shaft 27 extending up and down. The supports 24 are attached to the bed frame 9 in a pair, front and rear, with a gap between them, and have a front and rear symmetrical shape.

[0035] The support 26 has a shape that is bent into a substantially L-shape in plan view, and is attached to the rotating shaft 27 at the bent portion, and support pieces 28, 29 extending in two directions from the rotating shaft 27 have support sections 30, 31 formed at the tips thereof in the form of vertical through holes into which the lower ends of the posts 14 of the side fence 12 are inserted from above. Note that, although the support 26 has a bent shape in plan view here, this is not limited thereto, and it may have a straight shape, or may have a triangular or elliptical shape, for example.

[0036] This support 26 is prevented from rotating forward and backward by front and rear stopper pieces 32, 33 provided on the fixing device 25, and in this state, the side fence 12 is attached to the support portion 30 (31).

[0037] In addition, when the side rail 12 can be attached to the support device 26, the amount of protrusion W4 by which the support portion 31 formed on one support piece 29 protrudes toward the side of the bed frame 9 is greater than the amount of protrusion W3 by which the support portion 30 formed on one support piece 28 protrudes toward the side of the bed frame 9.

[0038] In the support body 24, as shown in Figure 4(a), one support piece 28 is abutted against the stopper piece 32, and the other support piece 29 is oriented so as to face in a direction perpendicular to the bed frame 9, and the side fence 12 is attached to the support portion 31 of the support piece 29, so that the side fence 12 can be caused to protrude relatively far from the side of the bed frame 9.

[0039] Furthermore, in the support body 24, as shown in Figure 4(b), the other support piece 29 is abutted against the stopper piece 33, one support piece 28 is oriented so as to face in a direction perpendicular to the bed frame 9, and the side fence 12 is attached to the support portion 30 of the support piece 28, so that the side fence 12 can be placed in a state in which it protrudes relatively slightly from the side of the bed frame 9.

[0040] Furthermore, as shown in FIG. 4(c), the support body 24 can be put into a position between the position in FIG. 4(a), in which the amount of protrusion is large, and the position in FIG. 4(b), in which the amount of protrusion is small, to store the support pieces 28, 29.

[0041] [Example 3] The support body in Examples 1 and 2 is configured to have multiple (here, two) support parts with different amounts of protrusion to the side of the bed frame, but it may also be configured with only one support part.

[0042] As shown in Fig. 5(a), in the support body 34 according to the third embodiment, a reinforcing frame 35 is attached to the side of a bed frame 9, and mounting holes 36, 37 are formed in the bed frame 9 and the reinforcing frame 35, respectively, penetrating vertically, and a base end (through hole 40) of a fixing device 39 is attached to one of the mounting holes 36, 37 with a fastener 38, and a support 41 is attached to the tip of the fixing device 39 by a rotating shaft 42 extending vertically so as to be rotatable forward and backward (left and right in Fig. 5). The support bodies 34 are attached to the bed frame 9 or the reinforcing frame 35 in a pair of front and rear with a gap between them, and have a front and rear symmetrical shape.

[0043] The support device 41 has a support portion 43 in the form of an up-down through hole at its tip for inserting the lower end portion of the support post 14 of the side fence 12 from above, and rotation is prevented by a stopper piece 44 provided on the fixing device 39, and in this state the side fence 12 is attached to the support portion 43.

[0044] In the support body 34, as shown in Figure 5 (b), a fixing device 39 is attached to the mounting hole 37 of the reinforcing frame 35, the support device 41 is abutted against the stopper piece 44 and oriented in a direction perpendicular to the bed frame 9, and the side fence 12 is attached to the support portion 43, so that the side fence 12 can be made to protrude relatively significantly from the side of the bed frame 9 (protrusion amount W6).

[0045] Furthermore, in the support body 34, as shown in Figure 5 (c), by attaching a fixing device 39 to the mounting hole 36 of the bed frame 9, abutting the support device 41 against the stopper piece 44 and oriented so as to face in a direction perpendicular to the bed frame 9, and attaching the side fence 12 to the support portion 43, the side fence 12 can be made to protrude relatively slightly from the side of the bed frame 9 (protrusion amount W5).

[0046] Furthermore, in the support body 34, as shown in FIG. 5(d), by attaching a fixing device 39 to the mounting hole 36 of the bed frame 9 and rotating the support device 41 toward the bed frame 9, the support device 41 can be stored.

[0047] [Example 4] In the supports according to Examples 1 to 3, the amount of protrusion of the support part is changed by rotating the support tool relative to the fixing tool, but the amount of protrusion of the support part may also be changed by moving the support tool back and forth relative to the fixing tool.

[0048] As shown in Fig. 6, the support body 45 according to the fourth embodiment has a cylindrical fixture 46 attached to the side of the bed frame 9, and a base end of a support 47 is inserted into the hollow part of the fixture 46 so as to be movable forward and backward. A support part 48 in the form of a vertical through hole is formed at the tip of the support 47, into which the lower end of the support post 14 of the side fence 12 is inserted from above. The support 47 is fixed by a fastener 50 via a long hole 49 formed in the fixture 46, and is capable of moving forward and backward along the long hole 49 in a direction perpendicular to the bed frame 9.

[0049] Furthermore, in the support body 45, as shown in Figure 6 (a), by extending the support member 47 relative to the fixing member 46 and attaching the side rail 12 to the support portion 48, the side rail 12 can be made to protrude relatively far from the side of the bed frame 9 (protrusion amount W8).

[0050] Furthermore, in the support body 45, as shown in Figure 6 (b), by retracting the support device 47 from the fixing device 46 and attaching the side fence 12 to the support portion 48, the side fence 12 can be made to protrude relatively slightly from the side of the bed frame 9 (protrusion amount W7).

[0051] [Example 5] The supports according to Examples 1 to 4 are configured so that the amount of overhang is changed by changing the position of the support relative to the fixing device, but the support itself may be configured so that the amount of overhang is changed by changing its position.

[0052] As shown in Figure 7(a), the support body 51 of Example 5 has a base end (through hole 52) which is attached by a fastener 38 to one of the mounting holes 36, 37 formed in the bed frame 9 and the reinforcing frame 35, respectively, and a support portion 53 in the form of an upper and lower through hole is formed at the tip end for inserting the lower end of the support post 14 of the side rail 12 from above.

[0053] Furthermore, as shown in Figure 7(b), the support body 51 is attached to the mounting hole 37 of the reinforcing frame 35 and oriented in a direction perpendicular to the bed frame 9, and the side rail 12 is attached to the support portion 53, so that the side rail 12 can be made to protrude relatively significantly from the side of the bed frame 9 (protrusion amount W10).

[0054] Furthermore, by attaching the support body 51 to the mounting hole 36 of the bed frame 9 and orienting it in a direction perpendicular to the bed frame 9, as shown in Figure 7 (c), and attaching the side rail 12 to the support portion 53, the side rail 12 can be made to protrude relatively slightly from the side of the bed frame 9 (protrusion amount W9).

[0055] As described above, the bed 1 has supports 15, 16 (24, 34, 45, 51) that extend outward from the sides of the bed frame 9, and side rails 12 attached to the support portions 21, 23 (30, 31, 43, 48, 53) of the supports 15, 16 (24, 34, 45, 51).

[0056] The bed 1 is configured such that the supports 15, 16 (24, 34, 45, 51) are mounted on the sides of the bed frame 9 in a position changeable manner so that the protrusion amounts W1, W2 (W3 to W10) of the support portions 21, 23 (30, 31, 43, 48, 53) of the supports 15, 16 (24, 34, 45, 51) can assume different positions.

[0057] Therefore, in the bed 1 configured as described above, even if the pedestal 2 that supports the body of a recumbent person has different left and right widths, the side rails 12 can be attached to the common bed frame 9, reducing the manufacturing cost of the bed 1 and reducing the management burden on the business operator. Note that pedestals 2 with different left and right widths may be attached to a common bed frame 9, and a common bed frame 9 may be attached to a common pedestal 2 whose left and right width is changeable.

[0058] In addition, the bed 1 having the above-mentioned configuration has the supports 15, 16 (24, 34, 45, 51) separated into a front support 15 (24, 34, 45, 51) that supports the front side of the side rail 12, and a rear support 16 (24, 34, 45, 51) that supports the rear side of the side rail 12.

[0059] Therefore, in the bed 1 having the above configuration, the weight of each of the front and rear supports 15, 16 (24, 34, 45, 51) can be reduced, and the workload when changing the position can be reduced.

[0060] Further, the bed 1 is configured such that the supports 15, 16 have a plurality of supports 18, 19 in which the protruding amounts W1, W2 of the support portions 21, 23 are different.

[0061] Therefore, in the bed 1 configured as described above, the amount of extension of the side rails 12 can be easily selected visually by using multiple supports 18, 19, thereby further reducing the workload when changing posture. [Explanation of symbols]
