Technical Field

[0001] The invention relates to a toilet assisting device for elderly people, belonging to the technical field of toilet equipment. Background Art

[0002] Due to the decline of various physical functions, the elderly have slow movements, difficulty in squatting and standing up during the toilet process. In order to solve the above problems in the elderly's toilet process, a variety of toilet assisting devices have been developed in the market, which have solved the problem of the elderly's toilet to a certain extent. The existing toilet assisting devices are mainly divided into two categories. The first category is to install a steel frame support handrail next to the toilet. It has the advantage of simple structure, but it still needs to rely on the elderly's own strength to complete the squatting and standing up movements, and there is a defect of lack of assistance. The second category is an electric standing device, which provides uniform assistance to the elderly through a motor or a hydraulic rod to assist the elderly in going to the toilet. However, during the squatting or standing up process of the elderly, there is a characteristic that they need to stop at any time to adjust their posture or rest; and the use of uniform thrust to assist the elderly in standing up is very likely to cause a high safety risk caused by "external push and fall", which cannot meet the needs of the elderly to use the toilet. Therefore, it is necessary to develop a new toilet assisting device for the elderly to solve the above problems of the existing toilet assisting devices for the elderly. Summary of the invention

DETAILED DESCRIPTION

[0019] The toilet assist device for the elderly is composed of a seat plate 1, a support shaft 2 and two sets of assist units 3 (see the attached manual). Figure 1 and 2 ).

[0020] The two groups of power assist units 3 are arranged symmetrically (see the attached manual). Figure 1 and 2 The power assist unit 3 is composed of a support box 6, an arc rack 7, a transmission gear A8, a transmission gear B9, a transmission gear C10, a power assist tension spring 11, a transmission swing arm 12, a vertical sliding shaft 13 and a handrail 14 (see the attached manual). Figure 3 ).

[0021] The support box 6 is provided with an arc-shaped rack 7 (see the attached manual) by means of a slide rail. Figure 2 and 3 ). When the arc-shaped rack 7 is subjected to force, it can run along the track under the guidance of the slide rail.

[0022] The upper end of the arc-shaped rack 7 extends to the outside of the support box 6; the support shaft 2 is fixed between the upper ends of the arc-shaped racks 7 of the two groups of power-assisting units 3. The support shaft 2 is a "crankshaft" structure; the middle part of the support shaft 2 is movably equipped with a seat plate 1 (see the attached manual) through the rotating sleeve 4. Figure 2 The middle of the seat plate 1 is provided with a toilet hole 5. The purpose of arranging the support shaft 2 in this way is that when the power-assist device is in use, the seat plate 1 can be rotated and placed flat on the support shaft 2, and the support shaft 2 provides support for the seat plate 1 through the two side parts; and when the power-assist device is not in use, the seat plate 1 can be rotated to the "upward" state (see the attached manual). Figure 2 ), so that young people can use the toilet normally between the power-assisting units 3 when using it.

[0023] A vertical sliding shaft 13 is slidably mounted on one side of the arc-shaped rack 7 through a sliding groove; when the vertical sliding shaft 13 is subjected to force, it can slide up and down along the sliding groove under the guidance of the sliding groove. The upper end of the vertical sliding shaft 13 extends to the support box 6 and is fixed with a handrail 14 (see the attached manual). Figure 2 );

[0024] An auxiliary arm 15 is hinged at one end of the handrail 14 (see the attached manual). Figure 3 The support box 6 on one side of the handrail 14 is fixed with a positioning column 16; the auxiliary arm 15 is slidably connected with the positioning pin 18 on the positioning column 16 through the long sliding hole A17 (see the attached manual Figure 3 Since one end of the auxiliary arm 15 is slidably connected to the positioning column 16 through the long sliding hole A17 and the positioning pin 18, when the vertical sliding shaft 13 drives the armrest 14 to move up and down, the armrest 14 can drive the auxiliary arm 15 to move together, so that the auxiliary arm 15 can provide assistance to the elderly through the elbow part, thereby achieving the purpose of saving effort for the elderly to go to the toilet.

[0025] A transmission gear A8 and a transmission gear B9 are arranged between the vertical sliding shaft 13 and the arc-shaped rack 7; a transmission gear C10 is arranged below the transmission gear B9 through a rotating shaft 28; the transmission gear B9 is meshedly connected with the transmission gear A8 and the transmission gear C10; the transmission gear A8 is meshedly connected with the arc-shaped rack 7; (see the attached manual Figure 3 ).

[0026] When the arc-shaped rack 7 is in motion, the transmission gear A8 and the transmission gear B9 can drive the transmission gear C10 and the rotating shaft 28 to rotate synchronously.

[0027] The transmission swing arm 12 is fixedly mounted on the rotating shaft 28; the transmission swing arm 12 is connected to the support box 6 through the auxiliary tension spring 11 (see the attached manual Figure 3 One end of the transmission swing arm 12 is slidably connected to the long sliding hole B20 at the lower end of the vertical sliding shaft 13 through the transmission pin 19. Under the action of the elastic force of the booster spring 11, the transmission swing arm 12 and the vertical sliding shaft 13 always have a tendency to move downward.

[0028] The vertical sliding shaft 13 and the support box 6 are equipped with a locking device; the locking device is composed of a locking rack 21, a locking slider 22, a control slide bar 23 and a button 24 (see the attached manual Figure 3 and 5 ).

[0029] A locking rack 21 is fixedly mounted on the support box 6 on one side of the vertical sliding shaft 13; a plurality of locking ratchets inclined downward are evenly arranged on one side of the locking rack 21 (see the attached manual). Figure 5 ).

[0030] A control slide bar 23 is movably installed inside the vertical slide shaft 13 through a return spring 25; the upper end of the control slide bar 23 extends to the upper end of the handrail 14 and is equipped with a button 24; under the action of the return spring 25, the control slide bar 23 always has a tendency to move upward.

[0031] A locking slider 22 is installed on the vertical sliding shaft 13 at the lower end of the control slide rod 23 for transverse sliding. One side of the locking slider 22 is connected to the vertical sliding shaft 13 through a locking support spring 29. Under the action of the locking support spring 29, the locking slider 22 always has a tendency to move outward.

[0032] The lower end of the control slide bar 23 is provided with an extrusion slope 27 in an inclined shape; the locking slide block 22 is provided with a pressure slope 26; the extrusion slope 27 is slidably connected with the pressure slope 26. When the control slide bar 23 moves downward, the extrusion slope 27 and the pressure slope 26 can squeeze the locking slide block 22 to move inward.

[0033] When the elderly use the toilet assist device for the elderly to use the toilet, first rotate the seat plate 1 to be flat on the support shaft 2, at which time the seat plate 1 is at the highest point (see the attached manual). Figure 3 ). Then the old man holds the handrail 14 with both hands, puts his elbows on the auxiliary arm 15, and then leans on the seat 1. Then he presses the button 24, so that it drives the control slide bar 23 to overcome the elastic force of the return support spring 25 and then move downward; during the downward movement of the control slide bar 23, the locking slide bar 22 is squeezed by the pressing inclined surface 27 and the pressed inclined surface 26 to overcome the elastic force of the locking support spring 29 and then move inward, and disengage from the locking rack 21.

[0034] After the above process is completed, the elderly squats and squeezes the seat board 1, which pushes the arc rack 7 downward after being pressed; during the downward process of the arc rack 7, the transmission gear A8 and the transmission gear B9 drive the transmission gear C10 and the rotating shaft 28 to rotate clockwise (see the attached manual). Figure 3 ). The rotating shaft 28 drives the transmission swing arm 12 to rotate clockwise during the clockwise rotation; during the clockwise rotation of the transmission swing arm 12, the handrail 14 and one end of the auxiliary arm 15 are pushed upward through the vertical sliding shaft 13. In this process, the auxiliary tension spring 11 hinders the rotation of the transmission swing arm 12 through elastic force, and finally provides a certain resistance to the seat board 1 through the transmission gear C10, the transmission gear B9, the transmission gear A8 and the arc rack 7, thereby providing a certain resistance for the elderly to squat, thereby achieving the purpose of saving effort.

[0035] When the arc-shaped rack 7 descends to the limit position and cannot descend any further, the button 24 is released, and the control slide bar 23 is reset by the elastic force of the return spring 25; the locking slide block 22 is clamped into the locking ratchet of the locking rack 21 under the elastic force of the locking spring 29 (see the attached manual). Figure 4 ), so that the vertical sliding shaft 13 is locked and connected with the locking rack 21 through the locking slider 22, thereby achieving the purpose of locking the power assist device. Then the elderly can go to the toilet.

[0036] When the elderly person needs to get up after using the toilet, he presses down the button 24 to disengage the locking slider 22 from the locking rack 21. Then, the armrest 14 is pressed down to make the vertical sliding shaft 13 move downward under the action of pressure. During the downward movement of the vertical sliding shaft 13, the transmission swing arm 12 can be driven to rotate counterclockwise through the long sliding hole B20 and the transmission pin 19; during this process, the auxiliary tension spring 11 can also pull the transmission swing arm 12 to rotate counterclockwise through elastic force. During the counterclockwise rotation of the swing arm 12, the arc-shaped rack 7 can be pushed upward through the rotating shaft 28, the transmission gear C10, the transmission gear B9 and the transmission gear A8 (see the attached manual). Figure 4 ); During the upward movement of the arc-shaped rack 7, the seat board 1 can provide a certain amount of assistance for the elderly to stand up, thereby achieving the purpose of labor saving.

[0037] When the seat plate 1 moves upward to the highest position (i.e. the initial position), the power assist device can be restored to the initial state by releasing the button 24, and then the power assist device can enter the next working cycle.

[0038] When the power assist device is providing assistance to the elderly when squatting or standing up, the button 24 can be released at any time as needed, so that the control slide bar 23 is reset by the elastic force of the return support spring 25; the locking slide block 22 is engaged with the locking ratchet of the locking rack 21 by the elastic force of the locking support spring 29, so that the vertical slide shaft 13 is locked and connected with the locking rack 21 through the locking slide block 22, thereby locking the power assist device, and the elderly can rest or adjust their posture on the seat board 1. When the elderly have finished resting or adjusting their posture, they can press the button 24 to perform other operations.

[0039] The elderly toilet assisting device has a simple structure and ingenious design. It can provide a certain amount of resistance when the elderly squat when using the toilet, and can also provide a certain amount of thrust when standing up, and has a good assisting effect. When the assisting device of the present application is working, the elderly can lock it at any time to stop and adjust their posture or rest, thereby solving the problem that the existing toilet assisting devices cannot provide assistance or have high safety risks, and meeting the needs of the elderly to use the toilet.
