Description

Technical Field

[0001] This utility model relates to the field of assistive devices for the elderly, specifically a mechanical assistive sitting device installed at the rear of a toilet, which is particularly suitable for solving the problem of difficulty for the elderly to get up independently after using the toilet. Background Technology

[0002] Due to the decline in limb strength, elderly people often need external support to get up after using the toilet; existing toilet-standing assistance devices have the following main drawbacks.

[0003] 1. Lack of effective lifting assistance: Traditional handrails only provide static support, and users still need to rely on their arms and waist to complete the standing action, which still poses a risk of falling for elderly people with severe muscle weakness.

[0004] 2. Insufficient lateral stability: The connection between the ordinary L-shaped handrail and the toilet is a point connection, which can easily cause lateral swaying when the user gets up, especially when the body's center of gravity shifts, which may lead to a tipping accident.

[0005] 3. Poor cleanability: The bracket structure requires ground support, creating dead corners for hygiene, making it difficult to clean and prone to bacterial growth over long-term use. Utility Model Content

[0006] In order to overcome the problems of difficulty for the elderly to get up after using the toilet, unstable lateral support, and difficulty in cleaning hygiene dead corners in the existing technology, this utility model provides an elderly toilet sit-up device. Through an adjustable support frame combined with a linkage lifting mechanism, arc-shaped trajectory constraint and a supportless hanging inverted L-shaped handrail assembly, it enables the elderly to get up independently with zero effort, zero lateral tilting during the standing process, and zero hygiene dead corners in the usage scenario.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: an elderly toilet seat-raising device, including a support frame consisting of an n-shaped frame plate fastened to the rear end of the toilet seat and strip-shaped frame plates bolted to both ends thereto, the frame plates extending along the length of the toilet seat; an assistive component including an electric cylinder fixed to the side of the frame plate, a guide rod arranged parallel to the electric cylinder, a sliding sleeve sleeved on the guide rod, a support rod hinged at one end to the top of the sliding sleeve and at the other end to the bottom front end of the toilet seat ring, and a connecting rod connecting the sliding sleeve and the electric cylinder rod at both ends respectively; when the electric cylinder extends or retracts, it drives the sliding sleeve to slide along the guide rod through the connecting rod, thereby driving the support rod to lift the toilet seat ring to achieve a 0°~85° rotation; a motion constraint mechanism including an arc-shaped plate sleeve fixed to the upper part of the frame plate and a sliding plate hinged at one end to the bottom front end of the toilet seat ring and slidably embedded in the plate sleeve at the other end; and a handrail assembly including a plate cover fixed to the outside of the frame plate, an inverted L-shaped frame rod connected to the plate cover at the bottom and extending horizontally at the top, and a support plate fixed to the upper part of the frame rod.

[0008] In the aforementioned elderly toilet sit-up device, the bolt connection holes between the frame plate and the n-shaped frame plate adopt a waist-shaped groove structure.

[0009] In the aforementioned elderly toilet sit-up device, both the electric cylinder and the guide rod are fixed to the side of the frame plate by C-shaped clamps.

[0010] In the aforementioned elderly toilet sit-up device, a linear bearing is embedded in the inner wall of the sliding sleeve.

[0011] The aforementioned toilet seat for the elderly has a tray surface covered with a non-slip silicone layer.

[0012] In the aforementioned elderly toilet sit-up device, the tray is welded and fixed to the frame rod by a reinforcing bar block 45.

[0013] The aforementioned elderly toilet sit-up device also includes a handrail assembly that is vertically welded to the bottom of the rod block 45, with the bottom of the rod bolted to a C-shaped clamp of an electric cylinder.

[0014] The aforementioned elderly toilet seat has a C-shaped metal cover that covers the assistive components.

[0015] In the aforementioned elderly toilet seat-lifting device, the toilet seat is independently placed on top of the assistive assembly.

[0016] The aforementioned elderly toilet sit-up device has a waterproof button embedded in the side wall of the tray that is wired to the electric cylinder controller.

[0017] The beneficial effects of this utility model are: 1. Mechanically assisted lifting: The electric cylinder pushes the sliding sleeve through the connecting rod, and the support rod lifts the toilet seat to achieve a 0°~85° rotation, eliminating the burden on the waist and legs; 2. Dynamic anti-tilt protection: The sliding plate constrains the track of the seat ring by sliding within the arc-shaped plate sleeve, and the inverted L-shaped frame rod and the support plate form rigid lateral support; 3. Zero dead corners for hygiene: The n-shaped frame plate is connected to the rear of the toilet, and the frame plate extends in the air without ground support. Combined with the cover to cover the auxiliary components, it eliminates the area where dirt accumulates. 4. Highly adaptable installation: The slotted bolt connection structure allows for fine-tuning of the support frame dimensions to accommodate different toilets; 5. Load-bearing reinforcement: The column and the electric cylinder clamping block form a parallelogram support, distributing the load on the support plate to prevent deformation.

[0025] This embodiment provides a toilet sit-up device for the elderly, aiming to solve the problem of difficulty in getting up after using the toilet. Through mechanical assistance and a stable support structure, it reduces the burden on the arms, waist, and legs when the elderly get up, while preventing the risk of lateral tipping. Figure 1-5 As shown, the toilet seat riser mainly consists of three parts: an n-shaped frame plate 1 and a support plate 2 connecting the frame as the basic support structure; an assistive component 3 that enables the electric lifting of the toilet seat; and a handrail component 4 that provides lateral support when getting up. The n-shaped frame plate 1 is made of metal and is fastened to the rear of the toilet seat and adjacent to the water tank. Its opening size matches the width of the rear of the toilet seat to ensure a stable fit. The support plate 2 is a strip of metal plate with both ends extending along the length of the toilet seat. It is connected to both ends of the n-shaped frame plate 1 by bolts. The bolt holes adopt a waist-shaped groove design to facilitate fine-tuning of the position during installation to adapt to different sizes of toilets. The toilet seat is not directly connected to the toilet seat, but is placed independently on the upper part of the assistive component 3 to ensure that it can rise and fall synchronously with the assistive component 3.

[0026] The power-assisted assembly 3 achieves smooth lifting of the toilet seat via electric drive. Its core components include an electric cylinder 31, a guide rod 32, a sliding sleeve 33, a support rod 34, a connecting rod 35, a sliding plate 36, and a plate sleeve 37. The electric cylinder 31 is horizontally positioned on one side of the frame plate 2 and fixed by two C-shaped clamps. The two clamps nest the cylinder body of the electric cylinder 31 and are bolted to the side of the frame plate 2. The guide rod 32 is arranged parallel to the electric cylinder 31, and its two ends are also fixed to the frame plate 2 by C-shaped clamps to ensure rigidity. The sliding sleeve 33 is fitted onto the surface of the guide rod 32 and can slide along its axial direction. A linear bearing is embedded in its inner wall to reduce friction. One end of the support rod 34 is hinged to the top of the sliding sleeve 33, and the other end is hinged to the front end of the bottom of the toilet seat, forming a movable connection. The two ends of the connecting rod 35 are respectively connected to the side of the sliding sleeve 33 and the cylinder rod end of the electric cylinder 31. The toilet seat is fixed with bolts. When the electric cylinder 31 extends or retracts, the connecting rod 35 pushes the sliding sleeve 33 to slide along the guide rod 32. When the cylinder rod of the electric cylinder 31 extends, the connecting rod 35 pushes the sliding sleeve 33 to slide forward. The support rod 34 gradually lifts the rear end of the toilet seat, achieving a 0°~85° rotation. The plate sleeve 37 is an arc-shaped metal sleeve, fixed to the upper part of the frame plate 2 near the cylinder rod of the electric cylinder 31. The sliding plate 36 is a metal plate with the same arc, one end of which is hinged to the bottom front end of the toilet seat, and the other end is slidably embedded in the plate sleeve 37. When the toilet seat rotates, the sliding plate 36 slides along the inner wall of the plate sleeve 37, constraining the movement direction of the toilet seat through the arc trajectory to prevent lateral deviation or shaking. The side wall of the support plate 43 is embedded with a waterproof button, which is connected to the controller of the electric cylinder 31 by wire to facilitate the control operation of the electric cylinder 31.

[0027] The handrail assembly 4 enhances the stability of elderly people when getting up through a multi-level support structure. Specifically, it includes a cover 41, a support rod 42, a support plate 43, and a column rod 44. The cover 41 is a C-shaped metal cover, which is fixed to the outside of the support plate 2 with bolts, covering part of the assistive assembly 3 structure, and also serving as the mounting base for the support rod 42. The support rod 42 is an inverted L-shaped metal rod, with its bottom welded to the side of the cover 41 and its top extending horizontally. The support plate 43 is an arc-shaped plastic plate with a surface covered with anti-slip silicone. It is fixed to the upper part of the support rod 42 by two rod blocks 45. The rod blocks 45 and the support rod 42 are welded with reinforcing ribs to improve the load-bearing capacity. The column rod 44 is vertically welded below one of the rod blocks 45. The bottom of the column rod 44 is connected to the C-shaped clamp of the electric cylinder 31 by bolts to form a parallelogram support, which distributes the force on the support plate 43 and prevents the support rod 42 from deforming.

[0028] When in use, the elderly person holds the non-slip surface of the support plate 43 and slowly sits down with the support of the inverted L-shaped support rod 42. At this time, the toilet seat remains horizontal and stationary, and the seat independently bears the weight. The arc-shaped constraint structure of the sliding plate 36 and the cover 37 prevents the seat from shifting to the side. When standing up, the elderly person presses the waterproof button on the side wall of the support plate 43 to start the electric cylinder 31. The electric cylinder 31 pushes the sliding sleeve 33 forward along the guide rod 32 through the connecting rod 35. The support rod 34 lifts the rear end of the seat to achieve a 0°→85° rotation. As the seat tilt angle increases, the elderly person naturally shifts their center of gravity upwards without having to exert force in their waist. During the process of standing up, the rigid connection between the support rod 42 and the cover 41 provides lateral stability until the elderly person is fully standing.
