Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a bed, particularly a rehabilitation bed suitable for training in standing up and walking, defecation, etc.

[Prior art and its problems]

Conventionally, when a person wants to get up from a regular bed and stand on the floor, he or she has to move his or her hips to the side of the bed before being able to put their feet on the floor. The bed described in Japanese Utility Model Application Publication No. 136324 of 1982 also has a notch on the side of the bed, but it is the same as moving the waist.

Therefore, this is not only a great burden, especially for patients who require rehabilitation training, but also
In this type of bed, it was very inconvenient to use the bed because the waist had to be moved.

In order to eliminate this inconvenience, the leg part of the bed lowers than before, allowing the patient to raise himself up to a sitting position without shifting his body, and then stand up from the lowered part or return to the sitting position. Beds have been developed that are convenient for people to relieve themselves.

However, even with this type of improved bed, the height of the descending part where the feet are attached is not the same as the floor surface, and there are steps and various obstacles are exposed, so when trying to practice walking, These steps and obstacles made it impossible to move forward, and the footing was unstable as the user had to walk on the descending bed at first, making it useless for walking training.

[Purpose of the invention]

The present invention has been made in order to solve the above-mentioned problems of the conventional art. To provide a bed that allows one to defecate easily in a comfortable posture.

[Structure of the invention]

In the present invention, the bed main body is constituted by a head side fixed part and a foot side movable part, the foot side movable part is divided into two in the width direction of the bed, and the lower side of the head side fixed part is opened and closed. A mechanism is placed thereon, and the movable parts are opened in the width direction of the bed by the opening/closing mechanism to expose the floor surface free of obstacles in the central part.

[Effect]

When the movable parts of the scaffolding are opened in the width direction of the bed, the floor surface itself is exposed without any obstructions, which, together with the tilted backrest of the bed, makes it easy to move on to walking training, while at the same time eliminating obstacles during defecation. Since there are no objects, you can take a comfortable position with your feet on the floor.

〔Example〕

In FIGS. 1 and 2, reference numeral 1 indicates a fixed part on the head side of the bed body, and reference numeral 2 indicates a movable part on the foot side of the bed body.

The head side fixed part 1 supports the upper part of the human body (patient) from the waist, and the foot side movable part 2 mainly supports the leg part.

The foot side movable section 2 is further divided into a right side movable section 2a and a left side movable section 2b.

On one side (fixed part 1 side) of the right side movable part 2a,
As shown in FIG. 3, a sliding pipe 3a is attached and extends toward the left movable portion 2b. Further, a sliding pipe 3b is similarly attached to the left side movable part 2b and extends toward the right side movable part 2a. These sliding pipes 3a, 3b are attached with vertically shifted positions. Furthermore, both sliding pipes 3a,
Elongated hole pieces 4a and 4b are attached to 3b.

As is clear from FIGS. 4 and 5, both the sliding pipes 3a and 3b are supported by a large number of roller bearings 5 attached to the head-side fixing part 1, and can slide left and right. It's becoming like that.

Incidentally, support pipes 6a and 6b are also attached to the opposite sides of both the movable parts 2a and 2b (see FIG. 2), and the support parts 1a and 6b extend forward from the head side fixed part 1, respectively. It is supported by a roller bearing 7 attached to the tip of 1b.

Reference numerals 8a and 8b are actuating rods, which are pivotally attached to the fixed portion 1 via support shafts 9a and 9b, so that they can be rotated left and right about the support shafts 9a and 9b.

A pin 10 is provided at the tip of the operating rods 8a and 8b.
a, 10b are provided, and the elongated hole pieces 4a,
They are each fitted into the elongated holes of 4b.

11a and 11b are rocking cam members, which are integrally attached to the operating shaft 12, and which are attached to the handle 1.
3, it is configured to rotate about the operating shaft 12 as a fulcrum.

Cam slots 11a' and 11b' are formed symmetrically in the swing cam members 11a and 11b, respectively.

These cam slot holes 11a', 11b' are provided with the above-mentioned operating rod 8.
The pins 14a and 14b of a and 8b are inserted,
As the swinging cam members 11a, 11b swing, the operating rods 8a, 8b are rotated left and right, respectively. The various elements that rotate the operating rods 8a and 8b, including the operating rods, are referred to as an opening/closing mechanism.

When the handle 13 provided on the side of the fixed part 1 is pulled up as shown in FIG. 6, the swing cam members 11a and 11b rotate about the operating shaft 12.

As the swinging cam members 11a, 11b rotate, the pins 14a, 14b of the operating rods 8a, 8b move along the cam slots 11a', 11b', and as shown in FIG. Rotate the rods 8a and 8b.

When the operating rods 8a, 8b rotate, the pins 10a, 10b at their tips move the long hole pieces 4a, 4b of the sliding pipes 3a, 3b in the left and right outward directions, and accordingly, the sliding pipes 3a, 3b, that is, the left and right movable parts 2a, 2b are opened left and right. Both movable parts 2
When a and 2b open left and right, the floor surface appears in the center.

Since the patient has previously raised his or her upper body on the bed backrest 15 which is erected into an inclined state by a conventionally known drive means (not shown), when the floor surface appears, the patient's feet are raised on the floor surface. Regarding the above,
Not only is it possible to get into a sitting position and stand up, but it is also possible to move forward to the floor in front of the bed without any hindrance.

The handrails 16a and 16b provided at the front edges of the movable parts 2a and 2b may be rotated as shown in FIG. 7 and used as handrails when starting to walk.

Reference numeral 17 is a defecation recess in which a toilet bowl is accommodated.

Note that the sliding pipes 3a, 3b and branch pipes 6a, 6b of the above embodiment may be solid rods.

〔Effect of the invention〕

The movable part of the foot side of the bed body is divided into two parts in the bed width direction, and each part is opened in the bed width direction so that the floor surface appears in the center, so there is no obstacle of any kind such as steps, and you can move your hips. Walking training can be started extremely easily without having to do anything, and since the user can sit in a stable position with his or her feet on the floor, the user can relieve himself in a comfortable position.
