Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a bed provided with an auxiliary mechanism for transferring onto the bed.

(Prior art) For example, a patient who has suffered a spinal cord injury may be paralyzed in motor function in the whole body or in a part of the body depending on the degree of injury, and training is therefore performed to quickly recover that function. . For such patients, a wheelchair is indispensable, and the movement of transferring between the bed and the wheelchair is performed on a daily basis.

(Problems to be Solved by the Invention) By the way, the above-mentioned movements must be performed by a normally functioning part of the body, such as the upper limbs, which is a great burden on the patient and requires no assistance. There are many cases where this cannot be done.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a bed that is provided with an auxiliary mechanism for transferring onto the bed so that the above-mentioned operations can be easily accomplished without an assistant.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides a bed in which a drive mechanism is attached below the floor of the bed, and a bed transfer assisting mechanism is dynamically connected to this drive mechanism. , the drive mechanism includes a motor and a screw shaft that is moved forward and backward by the motor, and the bed transfer assist mechanism includes a link connected to the screw shaft, a rod-shaped body attached to the link, and a rod-shaped body attached to the rod-shaped body. and an auxiliary seat divided into a plurality of parts, the auxiliary seat being raised and lowered between the lower part of the floor and the upper surface of the pinerest placed on the floor by the advancing and retreating movement of the screw shaft in the drive mechanism. That is.

Further, in the present invention, the auxiliary seat for transferring to the bed is slidably attached to the rod-shaped body.

(Function) When a patient in a wheelchair tries to transfer to the bed, when the bed transfer assist mechanism is activated, the screw shaft in the drive mechanism protrudes, the link is pressed outward in the width direction of the bed, and the auxiliary seat is moved toward the bed. It is pushed up to the height of the top of the pine tress. Next, the patient moves in front of the auxiliary seat and slides the auxiliary seat on the rod-shaped body in order to adjust the position of the auxiliary seat. In this case, since the auxiliary seat is divided into a plurality of parts, the frame of the wheelchair can be inserted between the auxiliary seats for bed transfer, and the patient can easily place his or her lower legs on the auxiliary seat. be able to. Then, the patient can easily lie down on the bed by placing his hands on the auxiliary seats located on both sides of his body and moving his body to the floor of the bed while supporting his body with his upper limbs.

(Embodiment) Next, an embodiment of a bed equipped with a bed transfer assisting mechanism according to the present invention will be described below with reference to the accompanying drawings.

In FIG. 1, reference numeral 1 indicates a bed equipped with a bed transfer assist mechanism, and this bed 1 includes:
A bed transfer assistance mechanism 3 is provided on the main frame 2 so as to be rotatable by a drive mechanism to be described later, and an operation switch S for operating the bed transfer assistance mechanism 3 is provided. This operation switch S will be described later, but by operating it, the bed transfer assisting mechanism 3
Can be operated up and down.

Next, as shown in FIG. 2, this bed transfer assisting mechanism 3 is attached to a support frame 5 provided on the main frame 2 on the legs 4 of the bed 1. In this case, the bed transfer assisting mechanism 3 is provided on both sides of the main frame 2, and the support frame 5 is connected to a motor 7 constituting the drive mechanism 6 of the bed transfer assisting mechanism 3, and the bed width of the support frame 5 is Links, which will be described later, are rotatably attached to both ends in the direction. The drive mechanism 6 has a screw shaft 8 attached to the motor 7 (see FIG. 3).
This screw shaft 8 is moved forward and backward by the motor 7.

As shown in FIG. 4, the bed transfer assisting mechanism 3 includes a link 9, a rod-shaped body 10 attached to the link 9, and an auxiliary seat portion 11a for bed transfer provided slidably on the rod-shaped body 10. , 11b, 11
It consists of c.

A screw shaft 8 attached to the motor 7 is connected to the link 9. The rod-shaped body 10 is
Base portion 12a of auxiliary seat portions 11a, 11b, 11c,
Sliding holes 13a, 13 formed in 12b, 12c
b, 13c, and the auxiliary seat portion 11a
11c can slide on the rod-shaped body 10 and can be adjusted to any position.

The bed 1 equipped with the bed transfer assisting mechanism according to the present invention is constructed as described above, and its operation will be explained next.

When a patient in a wheelchair wants to transfer to the bed 1, he operates the operation switch S with his elbow or the like to activate the bed transfer assistance mechanism 3 (see FIG. 5a). In the bed transfer assist mechanism 3, the motor 7 is driven;
As a result, the screw shaft 8 performs an operation in which the tip portion protrudes. Due to the protruding action of the screw shaft 8, the link 9 connected to the screw shaft 8 is pressed outward in the side direction of the bed and rotates about the fulcrum with the support frame 5. As a result, the auxiliary seats 11a to 11c for transfer are pushed up to approximately the same height as the top surface of the mattress of the bed.
The patient then moves the wheelchair to the undulated auxiliary seats 11a to 11c (see FIG. 5b).

Next, the patient sits on the auxiliary seat portions 11a to 1.
The auxiliary seats 11a to 11c are moved on the rod-shaped body 10 in order to adjust the position of the seat 1c. Thereby, the frame of the wheelchair can be inserted between the auxiliary seats for bed transfer. In this way, the auxiliary seat portions 11a to 1 for transferring to the bed are
1c can be moved on the rod-shaped body 10 to adjust the distance between them, so it can be used regardless of the standard or size of the wheelchair (see FIG. 6).

The patient supports his body by placing his lower legs on the auxiliary seat 11b and placing his hands on the auxiliary seats 11a and 11c,
By moving your body to the floor of the bed, you can lie down on the bed (Figures 5c and 5d).
reference).

In this embodiment, the bed transfer assisting mechanism 3 is provided on both sides of the bed 1, but it may be provided only on one side.

(Effects of the Invention) According to the present invention, the bed transfer assisting mechanism having the auxiliary seat portion for bed transfer which is divided into a plurality of parts is pushed up to the height of the upper surface of the bed mattress by the drive mechanism, and is formed protruding outward in the width direction. At this time, since the auxiliary seat for transferring to the bed is slidably provided on the rod-shaped body, the frame of the wheelchair can be inserted between the auxiliary seats for transferring to the bed, making the patient feel anxious. The lower limbs can be easily placed on the auxiliary seat without having to hold the lower limbs. Furthermore, the patient can place his/her hands on the auxiliary seat for transferring to the bed, support his or her body, and transfer to the floor of the bed, thereby significantly reducing the labor of the caregiver.
