JPS5816740Y2 - Lifting mechanism of toilet bowl in bed with toilet bowl - Google Patents

Description

[Detailed description of the invention] This invention supports the toilet bowl under the floor at all times, and when in use, raises it to expose it through an opening formed in the relevant part of the floor. This toilet is designed to allow a patient to defecate while lying supine on a bed, and in particular, the toilet bowl can be raised and lowered reliably using a simple mechanism.

The present invention will be described in detail below based on examples.

Reference numeral 1 designates a bed, and 2 designates a floor portion of the bed 1 that corresponds to the patient's waist.

An opening O communicating with the lower part can be freely formed in the floor part 2.

The opening O may be formed by horizontally sliding a divided lumbar pinerest together with a support plate, or a pinerest with the opening O formed in advance may be always loaded with a pinerest pad for the opening to facilitate defecation. Sometimes, the pinerest pad is moved downward to form the lumbar pinerest pad, or as shown in the figure, the divided end sides of the lumbar pinerests 3 and 3', which are divided into left and right sides, are oriented backwards together with the support plates 4 and 4', respectively. It may be formed by folding it downward, or any other method may be used.

Reference numeral 5 denotes a toilet support frame to which a toilet 6 can be fixed, and the toilet support frame 5 is fixed to a bed frame 8 via cross links 7, 7' so as to be movable up and down.

The bed frame 8 is provided with a rotating rod 9, and an operating arm 10 and a driving arm 11 are protruded from the rotating rod 9.

The actuating arm 10 is provided with a guide frame 12 and the cross link 7
The actuating pin 13 at 7' is movable along the guide frame 12, and the drive arm 11 is connected to the other side of a telescoping rod 14 whose one side is supported by the bed frame 8.

As shown in the figure, the telescopic rod 14 has a female thread 17 screwed into a lead screw 16 rotated by an electric motor 15.
The other side of the telescopic member 18 fixed to one side is attached to the drive arm 11.
In addition to having a bristled structure to fix it, a hydraulic cylinder or the like may also be used.

In this configuration, when the patient on the bed 1 feels inconvenient, the opening O is formed in the floor part 2 corresponding to the patient's waist by an appropriate mechanism, or after the opening O is formed, the mechanism is linked to the formation of the opening O. Then, the electric motor 15 is started and the telescoping rod 14 is extended, that is, the telescoping member 18 is moved to the left in the figure and the drive arm 1 is moved.
1, when the rotating rod 9 is rotated counterclockwise in the figure, the operating arm 10 is rotated upward.

Therefore, the actuating pin 13 of the cross link 7.7' is connected to the guide frame 12.
The toilet support frame 5 is raised by the operating arm 10 while moving along the toilet 6, and the toilet 6 can be raised to a predetermined position.

The toilet bowl 6 can then be lowered by reversing the electric motor 15 in the opposite direction as described above.

As described above, the present invention has a very simple mechanism as it raises and lowers the toilet support frame using cross links, has strong strength, can handle a large load, and operates reliably without causing any side-to-side shaking. be.

In particular, if a telescoping mechanism is applied to the telescoping rod for driving such a cross link by screwing a lead screw and a female screw, the telescoping rod will be automatically fixed at an appropriate telescoping position, that is, it will have a self-locking effect. There is no need for a separate stopper mechanism when fixing the toilet support frame, and in this sense as well, there is a great feature that the mechanism can be extremely simplified as described above.
