Description

Technical Field

[0001] The utility model relates to the field of medical and nursing instruments, in particular to an auxiliary getting-up device. Background Art

[0002] At present, the structures of toilet seats on the market are fixed. Once installed, the height of the toilet seat cannot be adjusted, resulting in great inconvenience for those with inconvenient leg activities when squatting and standing up during toilet use. Taking the elderly as an example, most of them have weak legs and need to rely on external forces or hold onto certain fixed objects with their hands to stand up smoothly. However, the long-term sitting position causes poor blood circulation in the lower limbs of the elderly, and they feel numb when standing up. In severe cases, they may fall due to loss of balance, posing a safety hazard.

[0003] Therefore, many products have emerged on the market that are used in conjunction with toilet seats to assist those with inconvenient leg activities in sitting down or standing up during toilet use. At present, most of the toilet seat auxiliary devices include a chassis, a link lifting structure, a cushion, and a driving component. The cushion is arranged on the link lifting structure, and the driving component is arranged between the chassis and the link lifting structure to drive the link lifting structure to move, so that the cushion realizes the lifting function. In this structure, in order to improve the aesthetics, the driving component is arranged at the rear side of the chassis, and the link lifting structure is arranged at the front side of the chassis, which plays a certain role in shielding the driving component, such as the patent document with the publication number CN112021981A. However, in the actual use process, a large number of clamping openings will be formed between the links of the link lifting structure. If these clamping openings are in a forward position, they are likely to come into contact with the trousers and accidentally clamp the trousers, causing inconvenience to the toilet user.

[0021] Combined with Figures 1 to 2 Further description is made on the assisted getting-up device of the present utility model.

[0022] An assisted getting-up device, characterized in that: it includes a chassis 1, a connecting rod lifting assembly 2, a linear motor 3 and a seat cushion assembly 4.

[0023] There are two sets of the connecting rod lifting assemblies 2, which are respectively arranged on the left and right sides of the chassis 1. Each set of the connecting rod lifting assembly 2 includes a main support rod 21, a first connecting rod group 24, a second connecting rod 23 and a third connecting rod group 22. Among them, the lower end of the main support rod 21 is fixed at a position on the chassis 1 close to the rear, and the upper end is inclined backward. The rear end of the first connecting rod group 24 is hinged at a position on the main support rod 21 close to the lower end, the rear end of the third connecting rod group 22 is hinged at a position on the main support rod 21 close to the upper end, the lower end of the second connecting rod 23 is hinged at the front end position of the first connecting rod group 24, and the position close to the upper end is hinged at the front end position of the third connecting rod group 22. The seat cushion assembly 4 includes a mounting plate 41 and a seat cushion 42. The left and right sides of the mounting plate 41 are fixed at the upper ends of the second connecting rods 23. The seat cushion 42 is fixed at the mounting opening of the mounting plate 41, and a cover body 43 is hinged at the rear end position of the seat cushion 42. The base tail of the linear motor 3 is connected to the front end position of the chassis 1 through a U-shaped hinge seat, and the piston rod head of the linear motor 3 is connected to the first connecting rod group 24 through a U-shaped hinge seat.

[0024] The chassis 1 includes two left and right support beams 11 and a positioning rod 12 arranged between the two support beams 11. Both ends of the positioning rod 12 are fixed to the inner sides of the two support beams 11 by bolts, playing a positioning role for the two support beams 11. Two sets of the connecting rod lifting assemblies 2 are respectively arranged on the two support beams 11.

[0025] The connecting rod lifting assembly 2 further includes a secondary support rod 26. The upper end of the secondary support rod 26 is welded and fixed to the main support rod 21, and the lower end is supported on the chassis 1, which can significantly improve the support strength for the seat cushion assembly 4.

[0026] The support beam 11 has an inclined positioning column 111 at a position close to the rear. The main support rod 21 is of a tubular structure. The lower end of the main support rod 21 is inserted on the positioning column 111 and fastened by bolts. That is, there are mutually docking connection holes on the positioning column 111 and the main support rod 21. After inserting a bolt into the docking connection holes and screwing on a nut, the main support rod 21 can be fixed on the positioning column 111 of the support beam 11. At the same time, after loosening the nut, the main support rod 21, that is, the entire connecting rod lifting assembly 2, can be removed from the chassis 1, which has the characteristics of convenient disassembly and assembly.

[0027] The upper end of the second connecting rod 23 is bent forward by 231, and an installation beam 25 extending backward is welded or bolted thereto. The edge position of the mounting plate 41 is supported on the installation beam 25 and fastened by bolts. After the upper end of the second connecting rod 23 is bent upward, the support of the second connecting rod 23 on the seat cushion assembly 4 can be moved forward, facilitating the sitting down and getting up of the user using the toilet.

[0028] Both left and right sides of the mounting plate 41 have downwardly folded side edges 411, and the side edges 411 and the installation beam 25 have mating connection holes. By inserting bolts and screwing nuts into the mating connection holes, the mounting plate 41 can be fixed to the installation beam 25, which has the characteristics of convenient disassembly and assembly.

[0029] The rear end of the installation beam 25 is bent downward to form a support portion 251, and the support portion 251 can support on the upper end position of the main support rod 21. The downwardly bent support portion 251 can cooperate with the inclined upper end wall of the main support rod 21 to enable the installation beam 25 to be stably supported on the top end position of the main support rod 21 through the support portion 251.

[0030] Both the first link group 24 and the third link group 22 each include two connecting plates 221 and a positioning tube 222 located between the two connecting plates 221. This structure can significantly improve the structural strength of the first link group 24 and the third link group 22, thereby ensuring the stability of the entire link lifting assembly 2 structure.

[0031] This embodiment further includes an armrest 4. The armrest 4 is a quadrilateral structure formed by bending a rod body. The rear end of the armrest 4 is connected to the rear end of the installation beam 25, i.e., the support portion 251, through a hinge seat, and the front end is supported on the edge position of the mounting plate 41. The armrest 4 can rotate around the rear end position for the convenience of the user using the toilet.

[0032] During use, when the lifter switches from the sitting position to the standing-up position, the linear motor 3 pushes the first link group 24 to rotate around the rear end position of the first link group 24. Under the limiting action of the third link group 22, the upper end of the second connecting rod 23 swings forward and upward, and at the same time drives the installation beam 25 and the seat cushion assembly 4 on the installation beam 25 to rotate forward and upward, playing a role in lifting the user using the toilet, facilitating the user to get up or sit on the seat cushion 42.

[0033] During use, since the lower end of the main support rod 21 is fixed at the rear position of the chassis, and the upper end is inclined backward, the link lifting assembly 2 is located at the rear position of the chassis 1, and it is not easy to contact the clothes and body of the user using the toilet. It will not clamp the clothes and body of the user using the toilet, which is convenient for the user to use and improves the safety during use. Secondly, the inclined setting of the main support rod in cooperation with the support of the auxiliary support rod can significantly improve the support strength of the entire link lifting assembly.
