Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention combines a bed and a functional chair.

[0002]

2. Description of the Related Art Beds or wheelchairs conventionally existing as commercial products all function independently. So bets are just bedding. Wheelchairs are movement chairs. Therefore, information on the combination of the removable bed and the functional chair of the present invention is unknown.

[0003]

By combining or separating the detachable bed 11 and the functional chair, a part of the bed is separated without transferring from the bed to the wheelchair when the patient goes to the medical treatment or rehabilitation from the hospital room. As a result, it can be used as a wheelchair, reducing the time and physical pain of patients and caregivers.

[0004]

The removable bed 11 has a space in a part of the bed, and the functional chair 2 is inserted into the space.
By forming the functional chair 2 in the form of the sleeping posture 6, the bed becomes a flat surface. In order to use the functional chair 2 as a wheelchair, the functional chair 2 is pulled out from the detachable bed 11, and after being used as a wheelchair, the functional chair 2 is inserted into the detachable bed 11 again and used as a bed.

In order to smoothly insert and remove the functional chair 2 with respect to the detachable bed 11, the detachable bed 1 corresponding to the front guide wheel 21 and the rear guide wheel 22 of the functional chair 2 is shown in FIG.
In FIG. 4, the guide wheel 23 of the detachable bed 11 is used for insertion and removal corresponding to the guide band 26 of the functional chair 2 in FIG. When the functional chair 2 is inserted to the fixed position of the detachable bed 11, the functional chair 2 hits the stopper 18 and stops. Various other methods for guiding and inserting the functional chair 2 into the detachable bed 11 are conceivable.

After the patient 1 uses the functional chair 2 as a wheelchair for medical treatment or rehabilitation, the functional chair 2 is used again as a bed in combination with the detachable bed 11. The embodiment will be described below with a structure excluding the cushioning material on the upper surface of the bed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A method for inserting a functional chair 2 into a predetermined position in a space inside a detachable bed 11 and stopping at a fixed position to form a bed is as follows. 2 can be advanced. However, since the guide plate and the car may be attached to either the detachable bed 11 or the functional chair 2, two methods are generated. 1 and 2 show the form of the detachable bed 11. When the detachable bed 11 is viewed from above, it is written in Chinese characters in the shape of (intermediate), and the place corresponding to the character (sun) is the position where the functional chair 2 enters. 1 and 2 are front views of the detachable bed 11, the plan view seen from above is a kanji gate.

The height of the detachable bed 11 depends on the length of the legs 25. The bed upper surface 17 and the waist frame 8 of the functional chair 2 are the same. The detachable bed 11 is provided with a guide bending portion 16 at the front entrance to facilitate insertion of the functional chair 2 into the upper guide rail 13 and the lower guide rail 14. In addition, a stop 18 is provided for setting the stop position of the functional chair 2.

The upper guide rail 13 of the detachable bed 11 shown in FIG.
The shape of the lower guide rail 14 is a belt surface, and the guide rail of the detachable bet 11 in FIG.

The first of the two methods described above will be described with reference to the drawings. FIG.
Is a view just before the functional chair 2 is inserted into the functional chair 2.
The vehicle has a rear wheel 19 and a front wheel 20 on the left and right side surfaces of the vehicle. As the functional chair 2 is inserted into the detachable bed 11,
A front guide wheel 21 and a rear guide wheel 22 attached to the left and right side surfaces of the functional chair 2 are guided into the detachable bed 11 along the upper guide rails 13 installed on both inner surfaces of the detachable bed 11 in FIG. Then, the functional chair 2 hits the stopper 18 of the detachable bed 11 and stops at a fixed position. Thereafter, the brakes of the rear wheels 19 and the front wheels 20 are locked.

FIG. 4 shows another method in which the functional chair 2 shown in FIG. 4 is inserted into the detachable bed 11 shown in FIG. 2. The detachable bed shown in FIG. 11 is that the upper guide rail 13 of the functional chair 2 is replaced by a guide belt 23 and the front guide wheel 21 and the rear guide wheel 22 of the functional chair 2 are replaced by a guide band 26. As the functional chair 2 is inserted into the detachable bed 11, the left and right side guiding bands 26 of the functional chair 2 are guided into the detachable bed 11 by the guide wheels 23 installed on both inner surfaces of the detachable bed 11 in FIG. Then, the functional chair 2 hits the stopper 18 of the detachable bed 11 and stops at a fixed position. Thereafter, the brakes of the rear wheels 19 and the front wheels 20 are locked.

Further, there is a method in which the detachable bed 11 can be inserted into and detached from the detachable bed 11 by guiding the rear wheel 19 and the front wheel 20 of the functional chair 2 by the lower guide rail 14 of the detachable bed 11 shown in FIG. is there.

FIG. 5 is a view in which the functional chair 2 is inserted in the form of the sitting posture 3 and the functional chair 2 hits the stopper 18 and stops, and is locked to the rear wheel 19 by the brake.

FIG. 6 is a view in which the stopped functional chair 2 is changed from the sitting position 3 to the regrinding position 5 by the mechanism of the functional chair 2, in which the backrest frame 12 and the footrest 15 are obliquely inclined.

FIG. 7 is a diagram in which the mechanism of the functional chair 2 changes the relining position 5 to the sleeping position 6, and the upper surface 17 of the detachable bed 11 and the functional chair 2 have the same plane height and the backrest. The frame 12 and the footrest 15 are also horizontal,
The surface of the detachable bed 11 and the surface of the functional chair 2 are integrated into a flat surface, forming a bed surface.

The above is a complete explanation, but when the patient 1 on the detachable bed 11 is transferred to medical treatment or rehabilitation,
By releasing the brake lock of the rear wheel 19 and the front wheel 20 of the functional chair 2 and pulling out the functional chair 2 from the detachable bed 11, the functional chair 2 functions as a wheelchair. The mechanical operation of the function chair 2 to change the patient 1 from the sleeping position 6 to the sitting position 3 via the relining position 5 and the sitting position 3 is performed when the function chair 2 is inserted into the detachable bed 11. It does not matter even when pulled out from the detachable bed 11.

The functional chair 2 used in the description is disclosed in Japanese Patent Application Nos. 10-377988 and 2000-21.
No. 0582 and Japanese Patent Application No. 2000-249060 show a functional chair 2 with wheels for movement. Therefore, as for the body position of the patient, the change from the sitting posture 3 to the standing posture 4 and the change from the sitting posture 3 to the relining posture 5 and further to the sleeping posture 6 are as already described.

[0018]

In order to raise a patient lying on the care bed currently in use, the caregiver changes the position of the patient on the bed from upward to sideways, and then makes the patient a right angle. Hands out of the bed and the caregiver wraps both hands on the patient's back, wraps the patient's hands around the caregiver's neck, and places the bet in a manner that the caregiver is holding the patient. Sit on the top once, and stand up again with the whole body with just the right posture. Most caregivers suffer from lower back and tibia pain from this oversized body. As a result, the removable bed 11 and the functional chair 2 of the present invention are provided.
The purpose of relieving the caregiver from occupational illness by attaching and detaching the garbage is to improve the effective utilization of the sickroom area due to the physical pain given to the patient and the general elimination of wheelchairs. Effects such as reduction of equipment costs are generated.
