Description

The present invention relates to a bed in which a support is provided on the side of the bed frame, protruding outward from the side of the bed frame, and a side rail is attached to the support part of the support.

Traditionally, beds have been provided with side rails on the sides of the bed frame to prevent people from falling.

In conventional beds, a support extending forward and backward is fixed to the side of the bed frame, and support parts for supporting the side rails are formed on the support at intervals forward and backward.

The side rails can be attached to the bed by inserting the vertically extending 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).

JP 2006-55529 A

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 must be prepared (produced) in advance, and businesses must also select (purchase) a bed that is suitable for the installation location and purpose.

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 base, which increases the manufacturing costs of the bed and also increases the management burden on the business operator.

Therefore, in the present invention according to claim 1, in 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 part of the support, the support is separated into a front support which supports the front side of the side rail, and a rear support which supports the rear side of the side rail, and the front support or the rear support has a number of supports each having a different amount of extension for its support part, and 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.

In addition, in the present invention related to claim 2, in a bed in which a support is provided on the side of a bed frame so as to extend outward from the bed frame, and a side rail is attached to the support part of the support, the support is separated into a front support which supports the front side of the side rail, and a rear support which supports the rear side of the side rail, and the front support or the rear support has a support device consisting of a plurality of support pieces whose respective support parts extend by different amounts, and the support is provided on the side of the bed frame in a position that can be changed so that the support parts of the support have different amounts of extension .

In addition, in the present invention relating to claim 3, in a bed in which a support is provided on the side of a bed frame so as to extend outward from the bed frame, and a side rail is attached to the support part of the support, the support is separated into a front support which supports the front side of the side rail, and a rear support which supports the rear side of the side rail, and the front support or the rear support has a support device which can be attached to the bed frame in a number of mounting states with different amounts of extension of the support part, and the support is provided on the side of the bed frame in a position which can be changed so that the amount of extension of the support part of the support can be different .

And the present invention has the following advantages:

In other words, in this invention, in a bed in which a support is provided on the side of a bed frame so that it protrudes 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 so that the protruding amount 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 recumbent person are different, the side rail can be attached to a common bed frame, which reduces the manufacturing costs of the bed and reduces the management burden on the business operator.

In particular, if 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, the weight of each front and rear support can be reduced, reducing the workload when changing positions.

In addition, if the support has multiple supports with different projection amounts for each support part, the projection amount of the side fence can be easily selected by visual inspection by using multiple supports, further reducing the workload when changing the position.

FIG.

The specific configuration of the bed according to the present invention will be explained below with reference to the drawings.

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.

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 leg, 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.

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 attached to the front end of the bed frame 9, and a headboard 11 attached to the rear end of the bed frame 9.

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 from each other in the front and back. Each side rail 12 has pillars 13, 14 extending up and down on the front and rear sides, and each pillar 13, 14 is supported by two supports 15, 16 attached to the sides of the bed frame 9 at a distance from each other in the front and back.

[Example 1]
As shown in Fig. 2, the supports 15, 16 according to the first embodiment are attached to the bed frame 9 at the base end of a fixture 17, and are attached to the tip end of the fixture 17 with a plurality of supports 18, 19 (two in this example) 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, 16 are symmetrical in shape.

One of the supports 18 extends in a straight line toward the side of the bed frame 9 in a plan view, and has a support section 21 at its tip that is a vertical through hole for inserting the lower end of the support post 13 (14) of the side rail 12 from above.

In the front support 15, the stopper piece 22 formed on the front side of the fixture 17 prevents the support 18 from rotating forward beyond a position perpendicular to the bed frame 9, while in the rear support 16, the stopper piece 22 formed on the rear side of the fixture 17 prevents the support 18 from rotating backward beyond a position perpendicular to the bed frame 9.

The other support 19 has a shape that extends in a generally U-shaped bend toward the side of the bed frame 9 in a plan view, and the tip tool has a support section 23 in the form of a vertical through hole for inserting the lower end of the support post 13 (14) of the side rail 12 from above.

In the front support 15, the 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 in the rear support 16, the support 19 is prevented from rotating backward by one of the supports 18 abutting against the stopper piece 22 of the fixing device 17.

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. 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.

When the support members 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 W2 (see Figure 3) of the support member 23 formed on one support member 19 protruding to the side of the bed frame 9 is greater than the amount of protrusion W1 (see Figure 3) of the support member 21 formed on the other support member 18 protruding to the side of the bed frame 9.

In this way, by varying the projection amounts W1, W2 of the support portions 21, 23 of the multiple (here, two) supports 18, 19 provided on each support 15, 16, it is possible to change the amount by which the side rails 12 project laterally from the bed frame 9 when the side rails 12 are attached to each support 15, 16.

As shown in FIG. 3(a), this support 15 (16) can be positioned so that one support 18 abuts against the stopper piece 22 and the other support 19 abuts against the one support 18, and the side fence 12 is attached to the support portion 23 of the other support 19, allowing the side fence 12 to protrude relatively far from the side of the bed frame 9.

In addition, with the support 15 (16), as shown in FIG. 3(b), one of the supports 18 is abutted against the stopper piece 22, while 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 where it protrudes relatively slightly from the side of the bed frame 9.

Furthermore, in the support 15 (16), as shown in FIG. 3(c), both supports 18, 19 can be stored by rotating them toward the bed frame 9.

In the above embodiment 1, it is sufficient that the side fence 12 is attached to the bed frame 9 without moving back and forth. 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 this case, it is not necessary to form a stopper piece. Also, as long as the structure can prevent the supports 15 and 16 from rotating, it is not limited to the stopper piece 22. The same applies to the following embodiments 2 and 3.

[Example 2]
In the support body 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.

As shown in Figure 4, in the support 24 of Example 2, the base end of the fixing device 25 is attached to the bed frame 9, and the support 26 is attached to the tip of the fixing device 25 so that it can rotate back and forth (left and right in Figure 4) by a rotating shaft 27 that extends 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.

The support 26 is bent in a generally L-shape in plan view, and is attached to the rotating shaft 27 at the bent portion. At the tip of the support pieces 28, 29 extending in two directions from the rotating shaft 27, there are formed support sections 30, 31 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 is bent in plan view here, this is not limited thereto, and it may be a straight line, or may be a triangular or elliptical shape.

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 part 30 (31).

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 to 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 to the side of the bed frame 9.

As shown in FIG. 4(a), the support body 24 has one support piece 28 abutted against the stopper piece 32, and the other support piece 29 oriented in a direction perpendicular to the bed frame 9. The side rail 12 is then attached to the support portion 31 of the support piece 29, allowing the side rail 12 to protrude relatively far from the side of the bed frame 9.

In addition, as shown in FIG. 4(b), in the support body 24, 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 made to protrude relatively slightly from the side of the bed frame 9.

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

[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.

As shown in Fig. 5(a), in the support 34 of the third embodiment, a reinforcing frame 35 is attached to the side of the bed frame 9, and mounting holes 36, 37 are formed in the bed frame 9 and the reinforcing frame 35, respectively, which penetrate vertically. The 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 that it can rotate back and forth (left and right in Fig. 5). The supports 34 are attached to the bed frame 9 or reinforcing frame 35 in a pair of front and rear with a gap between them, and have a front and rear symmetrical shape.

The support 41 has a support section 43 at its tip, which is a vertical through hole for inserting the lower end of the support post 14 of the side fence 12 from above. Rotation is prevented by a stopper piece 44 provided on the fixing device 39, and the side fence 12 is attached to the support section 43 in this state.

As shown in FIG. 5(b), the support 34 has a fixing device 39 attached to the mounting hole 37 of the reinforcing frame 35, the support 41 is abutted against the stopper piece 44, and is oriented so as to face in a direction perpendicular to the bed frame 9. The side fence 12 is then attached to the support portion 43, allowing the side fence 12 to overhang relatively far from the side of the bed frame 9 (overhang amount W6).

In addition, as shown in FIG. 5(c), the support 34 can be configured to have a relatively small overhang (overhang amount W5) from the side of the bed frame 9 by attaching the fixing device 39 to the mounting hole 36 of the bed frame 9, abutting the support 41 against the stopper piece 44 and orienting it in a direction perpendicular to the bed frame 9, and then attaching the side fence 12 to the support portion 43.

Furthermore, in the support 34, as shown in FIG. 5(d), the fixing device 39 can be attached to the mounting hole 36 of the bed frame 9, and the support 41 can be rotated toward the bed frame 9, so that the support 41 can be stored.

[Example 4]
In the supports of 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.

As shown in Figure 6, the support 45 of Example 4 has a cylindrical fixture 46 attached to the side of the bed frame 9, and the base end of a support 47 is inserted into the hollow part of the fixture 46 so that it can move back and forth. The tip of the support 47 is formed with a support part 48 in the form of a vertical through hole into which the lower end of the support 14 of the side fence 12 is inserted from above. The support 47 is fixed with a fastener 50 via a long hole 49 formed in the fixture 46, and is designed to be able to move back and forth along the long hole 49 in a direction perpendicular to the bed frame 9.

Then, in the support body 45, as shown in FIG. 6(a), the support 47 is advanced relative to the fixing device 46, and the side fence 12 is attached to the support portion 48, so that the side fence 12 can be made to protrude relatively far from the side of the bed frame 9 (protrusion amount W8).

In addition, in the support body 45, as shown in FIG. 6(b), by retracting the support 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).

[Example 5]
In the support bodies according to Examples 1 to 4, the amount of protrusion is changed by changing the position of the support relative to the fixing device, but the support body itself may be configured to change the position of the support body itself to change the amount of protrusion.

As shown in FIG. 7(a), the support 51 of the fifth embodiment has a base end (through hole 52) attached to one of the mounting holes 36, 37 formed in the bed frame 9 and the reinforcing frame 35, respectively, with a fastener 38, and a support part 53 in the form of a vertical through hole is formed at the tip end for inserting the lower end of the support 14 of the side rail 12 from above.

Then, as shown in FIG. 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 far from the side of the bed frame 9 (protrusion amount W10).

In addition, as shown in FIG. 7(c), the support body 51 is attached to the mounting hole 36 of the bed frame 9 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 slightly from the side of the bed frame 9 (protrusion amount W9).

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

The bed 1 is configured such that the supports 15, 16 (24, 34, 45, 51) are arranged on the sides of the bed frame 9 in a position that allows the projection amounts W1, W2 (W3-W10) of the support parts 21, 23 (30, 31, 43, 48, 53) of the supports 15, 16 (24, 34, 45, 51) to be in different positions.

Therefore, in the bed 1 configured as described above, even if the width of the support platform 2 that supports the body of a recumbent person is different, 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. Support platforms 2 with different widths may be attached to a common bed frame 9, or a common bed frame 9 may be attached to a common support platform 2 whose width can be changed.

In addition, the bed 1 configured as described above 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.

As a result, in the bed 1 configured as described above, the weight of each of the front and rear supports 15, 16 (24, 34, 45, 51) can be reduced, and the workload when changing posture can be reduced.

The bed 1 is also configured such that the supports 15, 16 have multiple supports 18, 19 with different protrusion amounts W1, W2 of the support portions 21, 23.

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, further reducing the workload when changing positions.
