Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a wheelchair and a service vehicle, and more particularly, to a vertical reclining stretcher ascending / descending and moving back and forth.

[0002]

[Prior art]

 Conventionally, a dedicated lift can be used for getting on and off a wheelchair or assistance car for sick people who need assistance, especially those with severe physical disabilities and bedridden elderly people. Was there.

[0003]

[Problems to be solved by the device]

 Regarding the dedicated lift among those mentioned in the conventional technology, the range and number of equipment are limited. Therefore, assistance work is very difficult for a heavy person or a person who needs rest due to a medical condition.

[0004] Furthermore, nurses and nurses in hospitals and facilities have been given up as "low back pain" due to the continuous movements of "hugging" and "bending back", and are now called "occupational diseases".

[0005]

[Means for Solving the Problems]

 The present invention is intended to solve the above-mentioned drawbacks, and it will be explained with reference to FIGS. 1 and 2 that a suspending metal fitting (9) is provided on both side surfaces of a lower frame (17) of a lifting mechanism (8). A guide rail plate (6) is placed over the upper frame (18).

A full reclining type stretcher (3) is mounted and fixed on the upper part of the rotating machine of a stretcher carriage (1) having a cylindrical roller (4) and a rotating mechanism (2). In addition to the above-mentioned mechanism, the guide rail extension plate (11) is used to supplement the length of the guide rail plate (6), and the above mechanism is provided.

[0007]

[Embodiment of device]

 The situation in which the body is moved from the wheelchair (13) to the bed (14) will be described with reference to the action explanatory diagram. Conversely, when moving from the bed (14) to the wheelchair (13), the reverse process of the former is performed. Will be done.

The wheelchair (13) and the bed (14) are rarely at the same height, and the bed (14) is usually higher.

Therefore, as shown in FIG. 5, in the first procedure, the upper frame (18) is raised by operating the handle (7) of the elevating mechanism (8) in order to make both heights the same. The height of the guide rail plate (6) that is placed over the same as that of the bed (14) is the same.

In the second procedure, the guide rail extension plate (11) is connected to the guide rail plate (6) by the insert piece (12), and then the flu reclining stretcher (3) is leveled so that the moving person (M) faces upward. To do.

According to the third procedure from FIG. 6, the wheelchair (13) is moved to the bed (14) direction, the guide rail extension plate (11) is placed on the bed (14), and then the wheelchair (13) is braked. Rub

The fourth step is to push the stretcher carriage (1) along with the guide rail plate (6) on the guide rail extension plate (11) by hand in the direction of the bed (14), and perform a full reclining stretcher together with the stretcher carriage (1). After the wheelchair (13) is completely placed on the bed (14), the wheelchair (13) is withdrawn from the bed (14), so that the guide rail plate (6) and the guide rail extension plate (11) are separated from each other on the bed (14). Is in the state shown in FIG.

In the fifth procedure, since the wheelchair (13) has been dismissed, the wheel and wheel of the wheelchair (13) is swung around the full reclining stretcher (3) without coming into contact with the foot of the mover (M). Since the body and the bed (14) are parallel to each other as shown in FIG. 8, they are moved on the bed (14) by shifting them.

If a large-sized bath towel or the like is initially laid under the body in advance, the transition becomes smoother by pulling the body together with the towel.

[0015]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. The wheelchair loading / unloading assistance device of the present invention is one in which a person (M) moves while staying on a full reclining type stretcher (3). (See Figures 5-8)

Explaining the specific structure, the lifting mechanism (8) in the figure serves as a pedestal for attaching the wheelchair loading / unloading assistance device to the wheelchair (13), and its size is limited. Therefore,

The lengths of the vertical and horizontal sides of the lower frame (17) and the upper frame (18) of the lifting mechanism (8) are rectangular bodies that can be attached and detached in the rectangular frame of the seat receiving frame of the wheelchair (13), In addition, suspending metal fittings (9) are provided on both side surfaces of the lower frame (17) so that the upper surface of the upper frame (18) becomes equal to the upper side of the seat receiving frame. (See Figures 1 and 2)

The stretcher mechanism (8) supports the stretcher carriage (1) on the upper frame (18) and has guide walls (16) on both sides of the upper surface, a roller stopper (15) at one end and a receiving seat at the other end. A guide rail plate (6) having (5) is stacked and fixed.

The lifting mechanism (8) includes an arm (19.19) between a lower arm (17) suspended on a wheelchair (13) and an upper frame (18) fixed to the guide rail plate (6). Is composed of a parallel link mechanism (8) assembled in an x-shape by pin-connecting the center portions of each other and a lifting rod portion (10) interposed between both arms (19, 19). There is. One end of the arm (19, 19) is slidable in the left-right direction in the figure along the inside of the frame (17, 18). (See Figures 1 and 2)

A cylindrical roller (4) is provided in the lower portion, and the center portion of the seat portion (3a) of the full reclining type stretcher (3) and the center portion of the rotating mechanism (2) are provided at the upper portion of the seat portion (3). There is provided a stretcher carriage (1) in which a bottom surface portion of a) is superposed on an upper surface portion of the rotating mechanism (2).

3 and 4 show a guide rail extension plate (11) for supplementing the above-mentioned guide rail plate (6). It has a guide wall.

[0022]

[Effect of device]

 The present invention has been made in view of the problems of the prior art. It reduces the labor of the caregiver when moving from the bed to the wheelchair and vice versa, and the physical injury is reduced, and the care recipient is passive. The burden will be lighter and it will be possible to move while sitting or lying down. If the present invention is removed, the original wheelchair and service vehicle will be restored to their original shape, so that they can be used as usual.
