Description

  The present invention mainly relates to an assisting bed. More specifically, the upper surface is undulated to smoothly assist the user in changing the posture between the supine state and the seated state, and is also in the sitting position on the back knee. It is related to a couch for assistance with a simple posture.

  Conventionally, as a bed for smoothly and surely changing the posture of the user, an upper body support frame that can be raised and lowered on a flat rectangular horizontal fixing frame, a leg support frame that can be bent in a mountain shape, and these upper body support frames And a heel support frame interposed between the leg support frame and the heel support frame, the heel support frame is interlocked with the standing of the upper body support frame toward the upper body support frame side. There is one configured to tilt downward (for example, see Patent Document 1).

JP 2000-245574 A

The bed like Patent Literature 1 has the above-described configuration, and the mattress placed on the support frame can be supported even when the person on the bed is bent to change the posture from the supine state to the seated state. The upper body support frame and the heel part are dropped while the part placed on the upper part is made to follow the inclination of the heel support frame, and the placement position on the support frame is maintained without sliding on the support frame. It is smoothly and reliably deformed to a state substantially matching the refractive state of the support frame.
Therefore, it is necessary for the bed like Patent Document 1 to have a configuration in which the buttock support frame tilts downward from the leg support frame toward the upper body support frame in conjunction with the standing of the upper body support frame. In the state, the buttocks support frame is tilted and held. For this reason, when the user sits facing the leg support frame side of the bed or in the long sitting position, it can be used without any problem, but the user hangs his or her legs from the bed to the side facing either the left or right direction. When sitting in an end-sitting position, the seating surface is tilted to the left or right and cannot sit stably.
For this reason, when the user receives assistance from the assistant while sitting sideways and when the user stands up, the burden on the user's body is large and difficult for the user and assistant to use. In addition, it is difficult for the user to exercise his / her own ability to take an end-sitting posture or to stand up, and is inappropriate as a support bed for promoting the user's independence. .

  Accordingly, in view of the above-described situation, the present invention intends to solve the problem that the posture change between the user's supine state and the seated state is smoothly and reliably performed, and the user can stably maintain the end-sitting posture without burden. The point is to provide a bed that can be.

  The bed according to the present invention is a bed comprising a support frame and three or more bottoms arranged side by side in the longitudinal direction of the bed on the upper surface side of the support frame in order to solve the above problems. The back bottom located on the user's back and the seat bottom located on the buttocks are tiltable, and are located on both the left and right sides of the seat bottom and substantially the same as the upper surface of the seat bottom in the horizontal state. While having the upper surface which forms a plane, it was provided with the end seat part fixed to the said support frame.

  Here, in conjunction with the tilting of the back bottom, it is preferable that the seat bottom is tilted so that the back bottom side of the seat bottom is lowered during a back-up operation.

  Further, it is preferable that the end seat portion does not protrude outward from the bed.

According to the bed according to the present invention, the bottom tilts to smoothly and reliably change the posture between the user's supine state and the seated state, and the user can stably maintain the end-sitting posture without extra burden. There is a remarkable effect that it can.
In addition, the user can take a long sitting position or a half sitting position in the center in the width direction of the bed, and can take an end sitting position on both the left and right sides of the bed, and these postures can be easily changed.
In addition, the end sitting position is a posture that requires the user's own power compared to the long sitting position and the half sitting position, so it is effective in restoring muscle strength and awakening, and it is easy to take and maintain this end sitting position. The bed according to the present invention is suitable as a bed for helping the user to become independent.

  In addition, in conjunction with the tilting of the back bottom, the seat bottom tilts so that the back bottom side of the seat bottom descends during back-up operation. When the user changes the posture from the supine position to the sitting position, the user's pelvis is easily raised. In addition, when the user's pelvis is standing upright on the back of the bed, the user can smoothly change the posture from the long sitting position or the half sitting position to the end sitting position.

Furthermore, if the end seat portion does not protrude outwardly from the bed, the size of the bed does not increase, and the end seat portion is hidden by a normal substantially rectangular mat, resulting in an uncomfortable appearance. Absent.
In addition, the movement distance for the user to hang both lower limbs when taking the end sitting position is not as long as the size of the bed, and it is easier to change the posture from the long sitting position or the half sitting position to the end sitting position. It becomes.

It is a perspective view which shows the horizontal state of the bed which concerns on embodiment of this invention. It is a perspective view which similarly shows the back upper knee state of a bed. It is a front view which similarly shows the horizontal state of a bed. It is a front view which similarly shows the back upper knee state of a bed. It is a longitudinal cross-sectional view which similarly shows the partial expansion of the state on the back knee of a bed.

Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the embodiments shown in the accompanying drawings, and includes all the embodiments that satisfy the requirements described in the claims. It is a waste.
Further, in this specification, the direction from the back bottom to the leg bottom in the longitudinal direction of the bed is determined to be the front, the opposite direction is the rear, the left and right are determined to face forward, and the view seen from the right is a front view. To do.
Further, the end sitting position refers to a posture in which both lower limbs are hung on the end of the bed and sits down, and the long sitting position refers to a posture in which both lower limbs are extended.

  First, the configuration of the bed 1 according to the present embodiment will be described with reference to FIGS. 1 and 2.

As shown in the figure, the bed 1 includes a support frame 2 and four rectangular bottoms 3, 3,... Arranged in parallel in the longitudinal direction of the bed on the upper surface side of the support frame 2. In the bottoms 3, 3,..., A back bottom 31 positioned on the user's back and a substantially central seat bottom 32 positioned on the user's buttocks are freely tiltable. End seats 4 fixed to the support frame 2 are provided on both the left and right sides of 32.
The bed 1 moves the headboard 5 on the user's head side, the footboard 6 on the leg side, the lifting mechanism 7 for raising and lowering the bed 1, and the bed, like a general assistance bed. A caster 8 and its lock / release means 9 are provided.

  The support frame 2 has a caster 8 at a lower portion and is fixed to an upper side of a leg 10 having an elevating mechanism 7. A footboard 6 is attached to the front side, a headboard 5 is attached to the rear side, and four bottoms 3, 3,... Arranged in the longitudinal direction of the bed 1 are provided on the upper side. The support frame 2 is supported by a leg 10 whose height can be changed by the elevating mechanism 7 so as to elevate while maintaining a horizontal state.

  The bottom 3 is four pieces, and is formed in a size suitable for each part of a general body, the back bottom 31 corresponding to the upper body, the seat bottom 32 corresponding to the buttocks, the knee bottom 33 corresponding to the thigh, the knee There are leg bottoms 34 corresponding to the lower legs, and these are arranged in order from the user's head side. The back bottom 31, the knee bottom 33, and the leg bottom 34 have substantially the same width (length in the left-right direction) as the bed 1, and only the seat bottom 32 has a smaller width.

  The back bottom 31 is pivotally attached to the support frame 2 by being pivotally supported by the support frame 2 at the front side and supported by the support frame 2 at the rear side, and is driven on the upper body side fixed to the support frame 2 Since it is driven by a motor (not shown), it is possible to support the rising operation of the upper body of the user.

  The seat bottom 32 is pivotally supported by the support frame 2 at the front side and supported by the support frame 2 at the rear side, so that the seat bottom 32 is tiltably attached to the support frame 2 and is fixed to the support frame 2. Since it is driven by a motor, the user's pelvis stands up on the back of the bed 1 and can appropriately support the user's sitting operation. On both the left and right sides of the seat bottom 32, end seat portions 4, 4 having an upper surface substantially the same height as the upper surface of the seat bottom 32 are provided.

  The back bottom 31 and the seat bottom 32 are rotated by the upper body side drive motor provided in the support frame 2 so that the back side (the user's head side) is raised, and the seat bottom is interlocked with this. Rotate so that the rear side of 32 is lowered to change the position of the user from the supine state to the seated state. These back bottom 31 and seat bottom 32 are interlocked, but these two members are configured not to engage with each other.

  The knee bottom 33 is pivotally supported by the support frame 2 on the rear side (seat bottom 32 side) and is pivotally supported by the leg bottom 34 on the front side (leg bottom 34 side). For this reason, when the leg bottom 34 moves up and down, the knee bottom 33 tilts.

  The rear side of the leg bottom 34 is pivotally supported on the front side (leg bottom 34 side) of the knee bottom 33, and the rear side is supported by the support frame 2, so that the leg bottom 34 is attached to the support frame 2 so as to be tiltable. Since it is driven by a lower body side drive motor (not shown) fixed to 2, it moves up and down by operating as necessary. Since the knee bottom 33 tilts in accordance with the raising and lowering of the leg bottom 34, the burden on the user when raising both lower limbs of the user can be reduced.

The end seat portion 4 is fixed to the support frame 2 on both the left and right sides of the seat bottom 32.
Since the end seat portion 4 has an upper surface that forms substantially the same plane as the seat bottom 32 when the seat bottom 32 is in a horizontal state, a floor slip such as a user changing the position in the horizontal state. It is easy to perform an operation necessary for preventing or reducing muscular strength.
Moreover, since the end seat part 4 is substantially the same length as the seat bottom 32, it is in a single plate shape with the other bottoms 3, 3,. Can be maintained comfortably.
In addition, since the front side (the knee bottom 33 side) of the seat bottom 32 is pivotally supported by the support frame 2, the knee bottom 33 side of the seat bottom 32 is the end seat portion even when the bed 1 is on the back knee. 4 has the same height, and the posture change from the long sitting position to the end sitting position of the user can be easily performed.
Moreover, two grooves are provided on the upper surface of the end seat portion 4 as a slip stopper when the user is in the end seated posture.

  Next, the operation from the horizontal state of the bed 1 of this embodiment to the above-the-back knee state will be described with reference to FIGS.

FIG. 3 shows a front view of the bed 1 in a horizontal state, and FIG. 4 shows a front view of the bed 1 in a state above the back knee.
As shown in FIG. 3, in the bed 1 in the horizontal state, the bottoms 3, 3,... And the upper surfaces of the end seats 4 form substantially the same plane. For this reason, by laying mats or mattresses on the upper surfaces of the bottoms 3, 3,... And the end seats 4, the user can comfortably maintain the lying position, and can easily turn over, Operation by one's own power can be performed smoothly.

In order to place the bed 1 in the horizontal state on the back knee (FIG. 4), first, the lower body side drive motor is operated to raise the leg bottom 34 and tilt the knee bottom 33. Next, after confirming that the user's body is in an appropriate position, the upper body side drive motor is operated to tilt the back bottom 31 and the seat bottom 32.
At this time, if only the back bottom 31 is tilted, there is a deviation between the user's back and the back bottom 31, and therefore it is necessary to perform positioning care to release the force of the contact portion after the posture change. By tilting the seat bottom 32 in conjunction with the tilt of the bottom 31, this work can be made unnecessary or reduced.

  FIG. 5 shows a partially enlarged longitudinal sectional view of the bed 1 in the vicinity of the seat bottom 32 on the back knee.

As shown in the drawing, the seat bottom 32 is held in a state where the rear side (the back bottom 31 side) is lowered and inclined in the above-the-back knee state. For this reason, when the user enters the sitting state, the user's pelvis is likely to stand up, converting the user from the supine state to the sitting state without placing an extra burden on the user's body. can do.
On the other hand, the end seat portions 4 and 4 on both the left and right sides of the seat bottom 32 are held horizontally even in a state above the back knee, so that the user can easily take the end sitting position.
Accordingly, when the user desires the supine position, the bed 1 is set in a horizontal state, and when the user desires a long sitting position or a semi-sitting position, the user uses the back or the bed 1 as a back knee position, Since the end sitting position can be easily taken even in the above-knee state, the user can easily take the end sitting position regardless of the state of the bed 1.

  Further, with the above configuration, the distance between the back bottom 31 and the seat bottom 32 is longer in the above-the-back knee state than in the horizontal state of the bed 1. Thereby, even when the user's body is changed from the supine state to the seated state, extra abdominal pressure does not occur, and the burden on the user's body is small.

In addition, in the bed 1 in this embodiment, since the back bottom 31, the seat bottom 32, and the end seat part 4 are provided without being engaged with each other, they can be tilted independently, but these are engaged. Therefore, a simpler configuration can be obtained.
Moreover, although the end seat part 4 is made the same length as the seat bottom 32, it is not restricted to this, The thing extended to the knee bottom 33 or the leg bottom 34 side, the thing extended to the back bottom 31 side, or these both sides It may be extended.
