Description

The present invention relates to a reclining bed that has multiple flexibly supported supports for supporting the body of a person lying down.

In a reclining bed, a shoulder support, a back support, a buttocks support, a thigh support and a lower leg support are provided on the top of the base to support the body of a person lying down, and the shoulder support and back support, as well as the thigh support and lower leg support, can each be bent relative to the buttocks support, and the shoulder support and back support, or the thigh support and lower leg support can each be bent.

In this reclining bed, the optimal bending position between the shoulder support and the back support, and between the thigh support and the lower leg support, varies depending on the body (height, etc.) of the person lying down.

For this reason, in conventional reclining beds, the hinges between adjacent bed bases are shifted back and forth and then fixed so that the bending position can be changed (see, for example, Patent Document 1).

JP 2009-82396 A

In the conventional reclining beds described above, when changing the bending position, it was necessary to first remove the fixing device, shift the hinge forward or backward, and then fix the hinge with the fixing device.

As a result, changing the bending position was time-consuming and there was a risk of losing the fixing device.

Therefore, in the present invention as claimed in claim 1, in a reclining bed having multiple flexibly arranged support platforms for supporting the body of a person lying down, an intermediate platform is provided between adjacent support platforms, and a bending portion is formed between each support platform and the intermediate platform, while a connecting body is provided on the intermediate platform so as to be capable of rotating horizontally, and one of the support platforms and the intermediate platform is connected by the connecting body depending on the horizontal rotation direction of the connecting body, and bent at the bending portion formed between the other support platform and the intermediate platform.

In addition, in the present invention according to claim 2, in the present invention according to claim 1, an operating body is provided on the rotation axis of the connecting body.

In addition, in the present invention according to claim 3, in the present invention according to claim 2, the connecting body and the operating body are extended in the same horizontal direction relative to the rotation axis.

In addition, in the present invention according to claim 4, in the present invention according to claim 2 or claim 3, the receiving base and the intermediate base are connected by clamping the receiving base between the connecting body and the operating body.

And the present invention has the following advantages:

In other words, in this invention, in a reclining bed with multiple flexibly arranged support tables for supporting the body of a person lying down, an intermediate table is provided between adjacent support tables, a bending section is formed between each support table and the intermediate table, a connecting body is provided on the intermediate table so that it can rotate horizontally, and one of the support tables and the intermediate table are connected depending on the horizontal rotation direction of the connecting body, and are bent at the bending section formed between the other support table and the intermediate table, so that the bending position between adjacent support tables can be easily changed.

In particular, if an operating body is provided on the rotation axis of the connecting body, the connecting body can be easily rotated by the operating body.

In addition, if the connecting body and the operating body are extended in the same horizontal direction relative to the rotation axis, the bending position can be confirmed by the orientation of the operating body.

In addition, if the receiving base and the intermediate base are connected by clamping the receiving base between the connecting body and the operating body, the receiving base and the intermediate base can be firmly connected.

The same plan view. 1A is a plan view showing a bending position adjustment mechanism according to a first embodiment, and FIG. FIG. 13A is a front view, FIG. 13B is a plan view, and FIG. 13C is a side view showing a bending position adjustment mechanism according to a second embodiment. 13A and 13B are a plan view and a side view showing a bending position adjustment mechanism according to a third embodiment.

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

As shown in Figures 1 and 2, the reclining bed 1 has a support 3 for supporting the body of a person lying down on the upper part of a base 2 that is elongated in the front-to-rear direction when viewed from the front. For the sake of convenience, the foot side of a person lying down on the reclining bed 1 will be described as the front side, and the head side as the rear side.

The support base 3 is composed of a buttocks support base 4 for mainly receiving the weight of the buttocks of the lying person (supporting the buttocks of the lying person from below), an upper body support base 5 for mainly receiving the weight of the upper body (above the buttocks) of the lying person (supporting the upper body from below), and a lower body support base 6 for mainly receiving the weight of the lower body (below the buttocks) of the lying person (supporting the lower body from below).

The buttocks support 4 is fixed to the center of the base 2.

The upper body support 5 is pivotally attached at its front end to the rear of the base 2 (rear of the buttocks support 4) so that it can be raised and lowered relative to the base 2 and buttocks support 4.

This upper body support 5 is flexibly divided into a back support 7 for receiving the weight of the back (spine) below the shoulders (scapulae) of a person lying down (supporting the back (spine) below the shoulders (scapulae) of a person lying down from below), and a shoulder support 8 for receiving the weight of the shoulders and head above the shoulders (scapulae) of a person lying down (supporting the shoulders and head above the shoulders (scapulae) of a person lying down from below). Between the left and right rear ends of the back support 7 and the left and right front ends of the shoulder support 8, there are provided bending position adjustment mechanisms 9 for adjusting the bending position forward and backward.

The lower body support 6 is pivotally attached at its rear end to the front of the base 2 (forward of the buttocks support 4) so that it can be raised and lowered relative to the base 2 and buttocks support 4.

This lower body support 6 is flexibly divided into a thigh support 10 for receiving the weight of the thighs of a person lying down (supporting the thighs from below) and a lower leg support 11 for receiving the weight of the lower legs of a person lying down (supporting the lower legs from below). A bending position adjustment mechanism 9 is also provided between the left and right front ends of the thigh support 10 and the left and right rear ends of the lower leg support 11 to adjust the bending position forward and backward.

The support base 3 is configured as described above, and the upper body support base 5 is connected to a back tilting mechanism 12 for tilting the back support base 7 (rotating the back support base 7 up and down relative to the base base 2) and a shoulder tilting mechanism 13 for tilting the shoulder support base 8 (rotating the shoulder support base 8 up and down relative to the back support base 7), while the lower body support base 6 is connected to a thigh tilting mechanism 14 for tilting the thigh support base 10 (rotating the thigh support base 10 up and down relative to the base base 2). The back tilting mechanism 12, shoulder tilting mechanism 13, and thigh tilting mechanism 14 are connected to a control mechanism (computer) 15. An operation switch 16 is connected to the control mechanism 15.

In the reclining bed 1, the user (such as a reclining person or a caregiver) can operate the operation switch 16, which causes the control mechanism 15 to raise or lower the backrest mechanism 12, shoulder rest mechanism 13, and thigh rest mechanism 14, thereby setting the backrest support 7, shoulder rest 8, and thigh rest 10 to the desired inclination angle.

In addition, in the reclining bed 1, when the back support 7, shoulder support 8, or thigh support 10 is tilted to the desired angle, the bending position between the back support 7 and shoulder support 8 and the bending position between the thigh support 10 and lower leg support 11 can be adjusted forward and backward by the bending position adjustment mechanism 9.

[First embodiment]
3, the bending position adjustment mechanism 9 according to the first embodiment has an intermediate base 17 in the shape of a horizontally long rectangular rod, which has the same left-right width as the shoulder base 8 (thigh base 10) and the back base 7 (lower leg base 11) but a narrower front-to-rear width, between the adjacent shoulder base 8 (thigh base 10) and the back base 7 (lower leg base 11), and forms bending portions 18, 19 between the shoulder base 8 (thigh base 10) and the intermediate base 17, and between the back base 7 (lower leg base 11) and the intermediate base 17, respectively. The bending portion 18 is formed by supporting the front end of a bracket 20 attached to the lower front end of the shoulder base 8 (thigh base 10) and the rear end of a bracket 21 attached to the lower part of the intermediate base 17 by a shaft 22 so as to be freely rotatable. In addition, the bent portion 19 is formed by supporting the front end of a bracket 21 attached to the lower part of the intermediate base 17 and the rear end of a bracket 23 attached to the lower part of the rear end of the back support base 7 (lower leg support base 11) so that they can freely rotate on an axis 24.

The bending position adjustment mechanism 9 has a pivot shaft 25 that extends vertically up and down attached to the end of the intermediate base 17 so that it can rotate freely, and a connector 26 that is attached perpendicular to the pivot shaft 25. This allows the connector 26 to rotate back and forth horizontally. A notch 27 that extends forward and backward is formed in the vertical center of the end of the intermediate base 17, allowing the connector 26 to rotate 180 degrees forward and backward. In addition, notched connector grooves 28, 29 that extend forward and backward are formed in the vertical center of the ends of the shoulder support 8 (thigh support 10) and back support 7 (lower leg support 11). The connector 26 is rotated and inserted into these connector grooves 28, 29.

Furthermore, the bending position adjustment mechanism 9 has an operating body 30 at the lower end of the rotation shaft 25. The operating body 30 is perpendicular to the rotation shaft 25 and extends in the same horizontal direction as the connecting body 26.

As shown in FIG. 4(a), when the operating body 30 (connecting body 26) is rotated backward, the connecting body 26 is rotated and inserted into the connecting groove 28 of the shoulder support 8 (thigh support 10). This connects the shoulder support 8 (thigh support 10) and the intermediate base 17, and the shoulder support 8 (thigh support 10) and the back support 7 (lower leg support 11) are bent at the front bending portion 19.

On the other hand, as shown in FIG. 4(b), when the operating body 30 (connecting body 26) is rotated forward, the connecting body 26 is rotated and inserted into the connecting groove 29 of the back support 7 (lower leg support 11). This connects the back support 7 (lower leg support 11) and the intermediate base 17, and the shoulder support 8 (thigh support 10) and the back support 7 (lower leg support 11) are bent at the rear bending portion 18.

[Second embodiment]
As shown in FIG. 5, the bending position adjustment mechanism 31 according to the second embodiment has bending portions 18, 19 formed in the same manner as the bending position adjustment mechanism 9 according to the first embodiment.

In the bending position adjustment mechanism 31, a rotating shaft 32 extending vertically up and down is attached to the end of the intermediate stand 17 so that it can rotate freely, and a connector 33 is attached perpendicular to the lower end of the rotating shaft 32.

In addition, in the bending position adjustment mechanism 31, holders 34, 35 with a cross-section that is roughly horizontally U-shaped are attached to the underside of the ends of the shoulder support 8 (thigh support 10) and back support 7 (lower leg support 11), respectively. The connector 33 is inserted into these holders 34, 35 by rotating them. The holders 34, 35 have a lower piece 37 that opens and closes like a spring relative to an upper piece 36 that is fixed to the shoulder support 8 (thigh support 10) and back support 7 (lower leg support 11), and the lower piece 37 has a convex part 38 that is bent in a convex shape. This prevents the connector 33 inserted into the holders 34, 35 from easily coming out.

Furthermore, in the bending position adjustment mechanism 31, a disk-shaped operating body 39 with a larger diameter than the rotating shaft 32 is formed at the upper end of the rotating shaft 32. The operating body 39 is formed with a convex operating knob 40 that extends back and forth so that it can be rotated with a finger.

In the bending position adjustment mechanism 31, when the operating body 39 (connecting body 33) is rotated backward, the connecting body 33 is rotated and inserted into the holding body 34 of the shoulder support 8 (thigh support 10). This connects the shoulder support 8 (thigh support 10) and the intermediate base 17, and the shoulder support 8 (thigh support 10) and the back support 7 (lower leg support 11) are bent at the front bending part 19. On the other hand, when the operating body 39 (connecting body 33) is rotated forward, the connecting body 33 is rotated and inserted into the holding body 35 of the back support 7 (lower leg support 11). This connects the back support 7 (lower leg support 11) and the intermediate base 17, and the shoulder support 8 (thigh support 10) and the back support 7 (lower leg support 11) are bent at the rear bending part 18.

[Third Example]
As shown in FIG. 6, the bending position adjustment mechanism 41 according to the third embodiment has bending portions 18, 19 formed in the same manner as the bending position adjustment mechanism 9 according to the first embodiment.

In the bending position adjustment mechanism 41, a rotating shaft 42 extending vertically up and down is attached to the end of the intermediate stand 17 so that it can rotate freely, and a connector 43 is attached perpendicular to the upper end of the rotating shaft 42.

The bending position adjustment mechanism 41 also has an operating body 44 at the lower end of the rotating shaft 42. The operating body 44 is perpendicular to the rotating shaft 42 and extends parallel to the connecting body 43 in the same horizontal direction.

In the bending position adjustment mechanism 41, when the operating body 44 (connecting body 43) is rotated backward, the connecting body 43 and operating body 44 clamp the end of the shoulder support 8 (thigh support 10) from above and below. This connects the shoulder support 8 (thigh support 10) to the intermediate base 17, and the shoulder support 8 (thigh support 10) and back support 7 (lower leg support 11) are bent at the front bending portion 19. On the other hand, when the operating body 44 (connecting body 43) is rotated forward, the connecting body 43 and operating body 44 clamp the end of the back support 7 (lower leg support 11) from above and below. This connects the back support 7 (lower leg support 11) and the middle support 17, and the shoulder support 8 (thigh support 10) and back support 7 (lower leg support 11) are bent at the rear bending part 18.

As explained above, in the reclining bed 1, multiple support tables (back support table 7, shoulder support table 8, thigh support table 10, lower leg support table 11) that support the body of a person lying down are provided so as to be freely bendable, and an intermediate table 17 is provided between adjacent support tables (back support table 7, shoulder support table 8, thigh support table 10, lower leg support table 11), and bending parts 18, 19 is formed, and the connecting body 26 (33, 43) is provided on the intermediate base 17 so as to be freely rotatable horizontally. Depending on the horizontal rotation direction of the connecting body 26 (33, 43), one of the receiving bases (back receiving base 7, shoulder receiving base 8, thigh receiving base 10, lower leg receiving base 11) is connected to the intermediate base 17, and is bent at the bending parts 18, 19 formed between the other receiving base (back receiving base 7, shoulder receiving base 8, thigh receiving base 10, lower leg receiving base 11) and the intermediate base 17.

Therefore, in the reclining bed 1 configured as described above, the bending position (bending portions 18, 19) between adjacent supports (back support 7, shoulder support 8, thigh support 10, lower leg support 11) can be easily changed by horizontally rotating the connecting member 26 (33, 43).

The reclining bed 1 is also configured with an operating body 30 (39, 44) attached to the pivot shaft 25 (32, 42) of the connecting body 26 (33, 43).

Therefore, in the reclining bed 1 configured as described above, the bending position (bending parts 18, 19) between adjacent support tables (back support table 7, shoulder support table 8, thigh support table 10, lower leg support table 11) can be easily changed by horizontally rotating the operating body 30 (39, 44) without requiring special tools or complicated work such as removing and reinstalling parts.

In addition, in the reclining bed 1, the connecting body 26 (43) and the operating body 30 (44) are configured to extend in the same horizontal direction relative to the rotation axis 25 (42).

Therefore, in the reclining bed 1 configured as described above, the bending position (bending portions 18, 19) can be easily confirmed by visual inspection, etc., depending on the orientation of the operating body 30 (44).

In addition, in the reclining bed 1, the connecting body 43 and the operating body 44 clamp the support bases (back support base 7, shoulder support base 8, thigh support base 10, and lower leg support base 11) to connect the support bases (back support base 7, shoulder support base 8, thigh support base 10, and lower leg support base 11) to the intermediate base 17.

Therefore, in the reclining bed 1 configured as described above, there is no need to provide separate parts to connect the connecting body 43 to the support base (back support base 7, shoulder support base 8, thigh support base 10, lower leg support base 11). By clamping the support base (back support base 7, shoulder support base 8, thigh support base 10, lower leg support base 11) from above and below, the load is distributed to the connecting body 43 and the operating body 44, and the support base (back support base 7, shoulder support base 8, thigh support base 10, lower leg support base 11) can be firmly connected to the intermediate base 17.
