Regarding the footrest 40, for example, the contents of Japanese Patent Application No. 2012-096123 (invention name: footrest for bed, application date: April 19, 2012) are incorporated. This patent application is incorporated in its entirety by this reference. The footrest 40 is what is called a foot plate.
As shown in FIGS. 1 to 3, the footrest 40 includes an option receiver 41 attached to the bottom 11, a panel 42 (option) attached to the option receiver 41, and a cushion pad 43 covering the panel 42. ..

<Option receiver 41>
As shown in FIGS. 2 to 4, the option receiver 41 includes a first component 70 to which the panel 42 is attached, and a second component 50 that fixes the first component 70 to the bottom 11. The first component 70 is arranged in a pair in the second direction Y. The common panel 42 is attached to the pair of first components 70.

<First part 70>
As shown in FIGS. 2 and 3, the pair of first components 70 is arranged in the second direction Y. Each first component 70 includes a first member 71 and a second member 72.
The first member 71 includes a plate member 73 arranged on the bottom 11, a pipe member 74 arranged above the plate member 73, and a frame member 75 connecting the plate member 73 and the pipe member 74. The plate material 73 is placed on the upper surface of the bottom 11. The plate member 73 is arranged between the mattress 13 and the bottom 11. The plate material 73 and the pipe material 74 extend in the first direction X. The plate material 73 is formed in a flat plate shape.

As shown in FIG. 4, the frame member 75 extends upward from the plate member 73. The frame material 75 includes a first round material 75a and a second round material 75b. The first round material 75a and the second round material 75b are arranged in a plurality (one pair in the illustrated example) at intervals in the first direction X. The first round member 75a extends from the upper surface of the plate member 73 in the second direction Y and is then bent upward. A pipe member 74 is bridged between the upper ends of the pair of first round members 75a. The second round member 75b extends in the first direction X and connects the pair of first round members 75a.

As shown in FIG. 3, the second member 72 is attached to the pipe material 74. The second member 72 can move in the first direction X along the pipe material 74. The second member 72 is fixed at an arbitrary position on the pipe material 74. The second member 72 supports the panel 42. When the second member 72 moves in the first direction X, the panel 42 also moves in the first direction X.

In a side view when the second member 72 is viewed from the second direction Y, the second member 72 indicates the panel 42 in a state of being inclined with respect to the third direction Z. The second member 72 can change the inclination angle of the panel 42. The second member 72 fixes the inclination angle of the panel 42 at an arbitrary angular position. For example, as shown in FIG. 3, the second member 72 can fix the panel 42 in a posture in which the inclination angle is 0 degree (a posture in parallel with the third direction Z). The second member 72 can also adjust the position of the panel 42 in the third direction Z to an arbitrary height position.

In the footrest 40, the care receiver moves on the mattress 13 (on the bottom 11) by adjusting the angle of the panel 42, the position of the panel 42 in the first direction X, and the position of the panel 42 in the third direction Z. Without touching, the panel 42 can be applied to the sole of the care receiver. For example, the angle of the ankle of the care-receiver can be changed every predetermined time by changing the angle of the panel 42 to a different angle every predetermined time. As a result, the ankle of the care-receiver is not fixed at a constant angle, and the care-receiver can be prevented from having an apex.

<Second component 50>
As shown in FIG. 4, the second component 50 fixes the pair of first components 70 to the bottom 11 and attaches the panel 42 for the body support device 10 to the body support device 10. In the present embodiment, one second component 50 does not fix both of the pair of first components 70 to the bottom 11, but a plurality of second components 50 individually fixes each first component 70 to the bottom 11. .. A plurality of second components 50 are arranged in the first direction X with respect to each first component 70. The second component 50 is covered by the mattress 13. Each second component 50 includes a first member 51 disposed on the bottom 11, a second member 52 that rotates with respect to the first member 51 and contacts the bottom 11, a first member 51 and a second member 52. And a shaft 53 that connects the.

As shown in FIG. 5, the first member 51 is fixed to the first component 70. The first member 51 fixes the first component 70 to the bottom 11 by sandwiching a portion of the plate material 73 that avoids the frame material 75 with the bottom 11. The first member 51 includes a first surface 56 disposed in the vent hole 26d, a second surface 54 and a third surface 55 that project from the first surface 56 in the second direction Y and face each other with the bottom 11 interposed therebetween. A fourth surface 57 fixed to the first surface 56. The first surface 56, the second surface 54, and the third surface 55 are all formed in a plate shape. The first surface 56, the second surface 54, and the third surface 55 are formed, for example, by bending one plate into a U shape.

The second surface 54 is fixed to the upper surface of the plate member 73 of the first component 70. The second surface 54 extends from the plate material 73 in the second direction Y.
The first surface 56 extends downward from the second surface 54 along the third direction Z. The first surface 56 enters below the upper surface 26a of the bottom 11 through the vent hole 26d. The first surface 56 is arranged in the vent hole 26d located at the end of the plurality of vent holes 26d arranged in the second direction Y.

The third surface 55 extends from the first surface 56 in the second direction Y. The upper surface 26 a of the bottom 11 is arranged between the second surface 54 and the third surface 55. In other words, the second surface 54 and the third surface 55 face each other in the third direction Z with the upper surface 26a of the bottom 11 interposed therebetween.

The fourth surface 57 projects from the first surface 56 in the second direction Y. The fourth surface 57 projects from the first surface 56 toward the opposite side of the second surface 54 and the third surface 55. The fourth surface 57 is arranged in the ventilation port 26d. A pair of the fourth surfaces 57 is arranged at intervals in the first direction X.

The second member 52 is formed of a channel material (a U-shaped member when viewed from the front in the longitudinal direction). The first end portion 52a of the second member 52 is arranged between the pair of plate members on the fourth surface 57 of the first member 51. The shaft 53 penetrates the first end 52a and the fourth surface 57 in the first direction X. The second member 52 rotates with respect to the first member 51 by rotating around the shaft 53. In other words, the first member 51 and the second member 52 can be relatively displaced, and specifically, relatively rotate about the shaft 53.

The second member 52 is arranged in the vent hole 26d while being in contact with the bottom 11. At this time, the second member 52 extends in the second direction Y and is formed in an inverted U-shape in a front view seen from the second direction Y (longitudinal direction of the second member 52).
A notch 52c is provided in the second end 52b of the second member 52. The cutout 52c includes a first portion 52d and a second portion 52e. In a side view of the second member 52 viewed from the first direction X, the first portion 52d linearly extends in the second direction Y and the second portion 52e linearly extends in the third direction Z. The second portion 52e is inclined with respect to the third direction Z. With the second member 52 in contact with the bottom 11, the first portion 52d of the cutout 52c is arranged on the opening peripheral portion of the vent hole 26d on the upper surface 26a of the bottom 11. A portion of the second member 52 located below the first portion 52d of the cutout 26c is disposed in the ventilation port 26d.

When the second member 52 in contact with the bottom 11 rotates upward, the second member 52 separates from the bottom 11 (see the chain double-dashed line in FIG. 5 ). Then, when the first member 51 is pulled up from the vent hole 26d, the second component 50 (option receiver 41) is separated from the bottom 11. In this way, the second member 52 rotates with respect to the first member 51, whereby the length of the second component 50 in the second direction Y is adjusted, and the second component 50 is attached to and detached from the bottom 11.

It can be said that the second component 50 is a part of the peripheral edge of the one vent hole 26d and is arranged between the first region 11a and the second region 11b facing each other in the second direction Y. A lower portion of the second component 50 (in the illustrated example, a portion of the second component 50 that is located below the first portion 52d of the cutout 52c) is arranged in the one vent hole 26d. The lower portion of the second component 50 has the same size as the vent 26d in the first direction X or is slightly smaller than the vent 26d. The lower portion of the second component 50 has the same size as the ventilation port 26d in the second direction Y or is slightly smaller than the ventilation port 26d.

In the present embodiment, each of the first region 11a and the second region 11b is a part of the inner peripheral edge of the one vent hole 26d. Both ends of the second component 50 in the second direction Y are in contact with the first region 11a and the second region 11b, respectively. The first member 51 of the second component 50 contacts the first region 11 a of the bottom 11. At this time, the first member 51 (first surface 56) may not be in surface contact or line contact with the first region 11a, and may be in point contact. The second member 52 of the second component 50 contacts the second region 11b of the bottom 11. At this time, the second member 52 (the second portion 52e of the cutout 52c) may not be in surface contact or line contact with the second region 11b, and may be in point contact. When the option receiver 41 supports the panel 42 that receives a large load (user's load) as in the present embodiment, from the viewpoint of suppressing rattling of the second component 50 with respect to the bottom 11 in the second direction Y. It is preferable that the first member 51 and the second member 52 of the second component 50 are in surface contact or line contact with the first region 11a and the second region 11b, respectively.

When the footrest 40 is attached to the bottom 11, the option receiver 41 is attached to the bottom 11, and then the panel 42 and the cushion pad 43 are attached to the option receiver 41.
When the option receiver 41 is attached to the bottom 11, a pair of first components 70 are arranged on the bottom 11, and the first components 70 are fixed to the bottom 11 by the second component 50. At this time, the operator may completely remove the mattress 13 from the bottom 11 and work. Further, the operator may flip up the end of the mattress 13 and insert the first component 70 and the second component 50 between the mattress 13 and the bottom 11 to perform the work.

When arranging the second component 50 on the bottom 11, first, as shown in FIG. 6, the third surface 55 and the first surface 56 of the first member 51 are made to enter the bottom 11 through the ventilation port 26d. In addition, the second member 52 is rotated upward. Then, as shown in FIG. 7, the second surface 54 of the first member 51 is arranged on the upper surface 26 a of the bottom 11.

Then, as shown in FIG. 5, the second member 52 is rotated with respect to the first member 51 to bring the second member 52 into contact with the upper surface 26 a of the bottom 11. At this time, the opening peripheral edge portion of the vent hole 26d in the bottom 11 enters the notch 52c of the second member 52, and the opening peripheral edge portion contacts the second member 52.

As described above, in the second component 50 according to the present embodiment, the first member 51 and the second member 52 can be relatively displaced, as shown in FIG. In this embodiment, the first member 51 and the second member 52 relatively rotate around the shaft 53. When the second component 50 is attached to the bottom 11, the second member 52 is rotated with respect to the first member 51 while the first member 51 is arranged on the bottom 11, and the second member 52 is brought into contact with the bottom 11. As a result, both ends (the first member 51 and the second member 52) of the second component 50 come into contact with the first region 11a and the second region 11b of the bottom 11. In this state, for example, when the second component 50 (option receiver 41) tries to be relatively displaced with respect to the bottom 11 in the second direction Y, for example, the lower portion of the second component 50 causes the first region 11a and the second region This displacement is suppressed by hitting the region 11b (the inner peripheral edge of the vent hole 26d) or the like. As a result, the second component 50 is positioned with respect to the bottom 11.

According to the second component 50, the positioning of the second component 50 (optional receiver 41) with respect to the bottom 11 is performed by rotating the second member 52 (relatively displacing the first member 51 and the second member 52). It can be realized by such a simple operation. As a result, for example, even when the mattress 13 is arranged on the bottom 11, the option receiver 41 can be easily attached to and detached from the bottom 11, and the convenience of the option receiver 41 is improved. You can

The first member 51 includes a second surface 54 and a third surface 55. Therefore, by arranging the first member 51 on the bottom 11 so that the second surface 54 and the third surface 55 sandwich the bottom 11, the first member 51 can be positioned with respect to the bottom 11.
The first member 51 further includes a first surface 56. Therefore, when the second component 50 tends to be displaced relative to the bottom 11, this displacement can be suppressed by, for example, the first surface 56 abutting against the inner peripheral surface of the vent hole 26d. ..
As described above, the second component 50 can be positioned with higher accuracy with respect to the bottom 11.

The second component 50 is covered by the mattress 13. Therefore, the mattress 13 can prevent the second component 50 from coming off the vent hole 26d.

(Second embodiment)
Next, a body supporting device 10A according to a second embodiment of the present invention will be described with reference to FIGS. 8 and 9.
In the second embodiment, the same components as those in the first embodiment are designated by the same reference numerals, the description thereof will be omitted, and only different points will be described.

The body support device 10A according to the present embodiment includes a second component 90 instead of the second component 50 according to the first embodiment. The second component 90 is a component for attaching the panel 42 to the body supporting device 10A, similarly to the second component 50 according to the first embodiment. The second component 90 sandwiches the first component 70 with the bottom 11. One second component 90 is arranged between the pair of first components 70.

<Second component 90>
As shown in FIGS. 8 and 9, the second component 90 restricts the first component 70 from being unintentionally detached from the bottom 11. The second component 90 includes a first member 91 and a second member 92 that are arranged apart from each other in the second direction Y, and a third member 93 that connects the first member 91 and the second member 92.

The first member 91 and the second member 92 fix the first component 70 to the bottom 11. The first member 91 and the second member 92 have the same shape as each other. As shown in FIG. 9, the first member 91 and the second member 92 respectively project from the first surface 96 arranged in the vent hole 26d and the first surface 96 in the second direction Y, and sandwich the bottom 11 therebetween. The second surface 94 and the third surface 95 facing each other are provided. The first surface 96, the second surface 94, and the third surface 95 are all formed in a plate shape. The first member 91 and the second member 92 are formed by bending one plate into a U shape.

The second surface 94 is arranged on the upper surface of the plate member 73 of the first component 70. The second surface 94 is not fixed to the upper surface of the plate material 73 and can be separated from the plate material 73.
The first surface 96 extends downward from the second surface 94 along the third direction Z. The first surface 96 enters below the upper surface 26a of the bottom 11 through the vent hole 26d. The 1st surface 96 is arrange|positioned among the ventilation holes 26d arranged in the 2nd direction Y at the ventilation hole 26d located in the end.

The third surface 95 extends from the first surface 96 in the second direction Y. The plate member 73 and the upper surface 26 a of the bottom 11 are arranged between the second surface 94 and the third surface 95. In other words, the second surface 94 and the third surface 95 face each other in the third direction Z with the plate material 73 and the upper surface 26a of the bottom 11 interposed therebetween.

The third member 93 biases the first member 91 and the second member 92 toward the outside in the second direction Y (directions away from each other along the second direction Y). The third member 93 abuts the first surface 96 of each of the first member 91 and the second member 92 against the inner peripheral surface of the vent hole 26d. The third member 93 includes a first pipe member 97 and a second pipe member 98, a pin 99, and a spring 100.

The first pipe material 97 is fixed to one of the first member 91 and the second member 92 (the first member 91 in the illustrated example), and the second pipe material 98 is the first member 91 and the second member 92. It is fixed to the other of the members 92 (the second member 92 in the illustrated example). The first end 97a of the first pipe material 97 is inserted into the second pipe material 98. The pin 99 penetrates the second pipe material 98. The spring 100 is arranged in the second pipe member 98. The spring 100 is arranged between the first end 97a and the pin 99. The spring 100 receives a reaction force from the pin 99 and biases the first pipe member 97 in the second direction Y.

The second component 90 contracts by pushing the first member 91 and the second member 92 from both sides in the second direction Y. At this time, the insertion amount of the first end portion 97a of the first pipe member 97 into the second pipe member 98 becomes larger than that before the pushing, and the second component 90 contracts in the second direction Y. At this time, the spring 100 is compressed in the second direction Y between the first end 97a and the pin 99. When the pushing is released, the insertion amount is reduced by the restoring force of the spring 100, and the length of the second component 90 in the second direction Y is restored. That is, the first member 91 and the second member 92 are urged in directions away from each other. When the external force against this biasing force is adjusted, the length of the second component 90 in the second direction Y is adjusted.

Here, in the present embodiment, the end portion 73a of the plate material 73 of the first component 70 is folded back. The end portion 73a is formed in a hook shape that is bent twice at a right angle. The end portion 73a is hooked on the bottom 11 (foot bottom 25) from below the bottom 11. Since the end portion 73a is caught by the bottom 11, the first component 70 is prevented from being separated upward from the bottom 11. The end portion 73a may not be folded back.

When the option receiver 41 is attached to the bottom 11, the worker places the pair of first components 70 on the bottom 11 with the mattress 13 removed from the bottom 11. At this time, the end portion 73 a of the plate material 73 of each first component 70 is hooked on the bottom 11. Then, the pair of first components 70 is fixed to the bottom 11 by the second component 90.

Enter the mouth 26d. After that, when the pushing is released and the second component 90 is restored and deformed, the first member 91 and the second member 92 (first surface 96) abut the inner peripheral surface of the vent hole 26d, and the second component 90 bottoms. It is fixed at 11. At this time, each of the first member 91 and the second member 92 is in contact with the inner peripheral edge of the vent hole 26d located at the end of the plurality of vent holes 26d arranged in the second direction Y. In other words, the first member 91 and the second member 92 are in contact with a part (first region 11a and second region 11b) of the inner peripheral edge of each of the different ventilation holes 26d.

The technical scope of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

Like the body support device 10B according to the modification shown in FIG. 10, the option receiver 41 includes both the second component 50 according to the first embodiment and the second component 90 according to the second embodiment. Good. In this case, the second component 90 is arranged so as to be displaced in the first direction X with respect to the second component 50. Further, in this case, the plate member 73 does not include the bent end portion 73a unlike the body support device 10B according to the second embodiment described above. If the second component 50 and the above-described bent end portion 73a are provided, the second component 50 and the end portion 73a of the second component 50 and the end portion 73a of the first component 70 (the plate member 73) are arranged on the bottom 11. Both may hit the bottom 11. As a result, it may be difficult or impossible to arrange the first component 70 at a desired position.

In the present invention, like the second component 50 according to the first embodiment, the first member 51 and the second member 52 may be in contact with a part of the inner peripheral edge of one common ventilation port 26d. .. Like the second component 90 according to the second embodiment, the first member 91 and the second member 92 may be in contact with part of the inner peripheral edges of the different vents 26d.
The second component 50 and the second component 90 may be arranged in an opening different from the vent hole 26d.

The second member 52 of the second component 50 may not be the channel material. The second member 52 may not have the cutout 52c.

The option receiver 41 is not limited to the one for the footrest 40.
For example, the option receiver 41 may be used for the side support. The side support is provided at an end of the bottom 11 in the second direction Y. The side support has a cushioning property and projects slightly upward from the bottom 11. The side support contacts the care receiver when the care receiver on the bottom 11 turns over in the second direction Y and the care receiver moves to the end portion in the second direction Y. Thereby, the care receiver notices that he/she has reached the end portion in the second direction Y, and the fall of the care receiver from the bottom 11 (mattress 13) is suppressed.

The option receiver 41 may be used for other options (for example, so-called side rails or IV poles). The option refers to, for example, a component or device that contributes to the improvement of the functionality of the body supporting device when the option is attached to the body supporting device.
The option receiver 41 may be attached to the bottom 11 different from the foot bottom 25 (for example, the back bottom 21, the waist bottom 22, the knee bottom 24).

In addition, it is possible to appropriately replace the constituent elements in the above-described embodiments with known constituent elements within the scope of the present invention, and the above-described modified examples may be combined as appropriate.
