[0002] Toilet seats play a crucial role in toilet comfort. Traditional toilet seats can compress nerves in the legs and buttocks during prolonged sitting, causing pressure and numbness in the lower limbs. To improve comfort, designers have created toilet seats with a curved structure that conforms to the legs and buttocks, reducing pressure and discomfort.
[0003] Chinese invention patent application CN116113351A (2023.05.12) discloses an ergonomic toilet seat, wherein the seat includes a top circumferential seat arrangement surface having an inner edge, an outer edge, a front portion, and a rear portion, wherein the seat is substantially symmetrical about a bisecting center line from the front portion to the rear portion, the rear top seat arrangement surface includes a steeply upward curved portion from the front portion to the rear portion, and wherein the slope along the bisecting center line from the center point of the rear inner edge to the highest rear point is about 25 degrees to about 55 degrees.
[0004] As the industry has developed, one trend is that toilets are getting larger, and the size of the seat rings is also increasing. When ergonomic curved surfaces are designed on large seat rings, the buttocks are located within the curved surface, which can create a sliding sensation along the surface, affecting the user experience. Moreover, because the curved surface affects the support performance of the seat ring, the thighs and buttocks may feel tired after sitting for a long time. Utility Model Content
[0005] This invention addresses the shortcomings of existing technologies by providing an ergonomic toilet seat ring that improves toilet comfort, and is especially suitable for use with large-sized toilets.
[0006] To solve the above-mentioned technical problems, the objective of this utility model is achieved through the following technical solution:
[0007] An ergonomic toilet seat includes an upper ring and a lower ring that are interlocked to form a seat body. The surface of the upper ring is provided with different functional areas.
[0008] The outer edge of the upper ring is provided with an annular planar support area, which forms a support structure for the outer side of the human leg and buttocks.
[0009] The inner edge of the upper ring is provided with a non-circular arc-shaped pressure relief area. The arc-shaped pressure relief area is continuously provided on the left, right and rear sides of the inner edge. The arc-shaped surface of the arc-shaped pressure relief area slopes downward from the outside to the inside. The curvature of the arc-shaped pressure relief area is adapted to the curvature of the inner side of the human leg and buttocks.
[0010] In the aforementioned ergonomic toilet seat, the width of the outer contour of the seat body increases sequentially from front to back; the circumference of the seat body also increases sequentially from front to back.
[0011] In the aforementioned ergonomic toilet seat, the inner edge of the upper ring extends downward to form an inwardly turned-up edge, and the inwardly turned-up edge and the arc-shaped pressure-relief area form a smooth curved transition; the planar support area and the arc-shaped pressure-relief area form a smooth curved transition; preferably, the bottom of the inwardly turned-up edge and the arc-shaped pressure-relief area have approximately the same height.

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1-6 :
[0030] An ergonomic toilet seat includes an upper ring 1 and a lower ring 2 that are snapped together to form a seat body. The surface of the upper ring 1 is provided with different functional areas, wherein...
[0031] The outer edge of the upper ring 1 is provided with an annular planar support area 11, which forms a support structure for the outer side of the human leg and buttocks.
[0032] The inner edge of the upper ring 1 is provided with a non-circular arc-shaped pressure relief area 12. The arc-shaped pressure relief area 12 is continuously provided on the left, right and rear sides of the inner edge. The arc-shaped surface of the arc-shaped pressure relief area 12 slopes downward from the outside to the inside. The curvature of the arc-shaped pressure relief area 12 is adapted to the curvature of the inner side of the human leg and buttocks.
[0033] When a person sits on the upper ring 1, the outer sides of their legs and buttocks are in contact with the planar support area 11 (it should be noted that the planar support area 11 of this invention is not an absolute plane, but only an approximate plane), and the inner side of the buttocks is in contact with the curved pressure relief area 12. The planar support area 11 supports the outer sides of the legs and buttocks, which can generate sufficient upward support force for the human body and prevent the human body from sliding down. The curved pressure relief area 12 wraps around the inner side of the buttocks, which can make people feel more comfortable and reduce the pressure of the upper ring 1 on the buttocks, thus preventing the buttocks from sliding down.
[0034] Comparison Appendix Figure 1 The width of the outer contour of the seat ring body increases from front to back; the ring width of the seat ring body also increases from front to back. Generally, the width of the outer contour of a traditional seat ring body remains constant from the middle to the rear. Compared to a traditional seat ring body, the seat ring body of this embodiment allows the entire buttocks to rest on the seat ring, increasing the contact area of the buttocks and making people feel more comfortable.
[0035] The inner edge of the upper ring 1 extends downward to form an inner flange 13, which forms a smooth curved transition with the arc-shaped pressure-reducing area 12; the planar support area 11 also forms a smooth curved transition with the arc-shaped pressure-reducing area 12; preferably, the bottom of the inner flange 13 and the arc-shaped pressure-reducing area 12 have approximately the same height, and the inner flange 13 and the arc-shaped pressure-reducing area 12 are integrated. Since the front side of the seat ring has basically no pressure-reducing requirement, this embodiment designs it as an inner flange 13 structure to increase the inner ring area of the seat ring.
[0036] The lower ring 2 and the inner flange 13 are provided with downwardly extending arc-shaped positioning strips 21. The arc-shaped positioning strips 21 are integrally formed with the lower ring 2 and have the same outline as the inner ring. The arc-shaped positioning strips 21 are adapted to the toilet seat body, which can increase the compatibility between the seat ring and the toilet seat body and prevent it from shaking.
[0037] Comparison Appendix Figure 4 The upper ring 1 has a hinge seat 14 formed at its rear end. The front half of the upper ring 1 is horizontally distributed, and the rear half of the upper ring 1 and the hinge seat 14 are curved upward from front to back. Preferably, the curved surface is adapted to the curved surface of the back of the human buttocks.
[0038] Comparison Appendix Figure 2 and attached Figure 3 The bottom of the lower ring 2 is provided with several anti-slip pads 3. The lower ring 2 is provided with several assembly units corresponding to the anti-slip pads 3. Each assembly unit includes an assembly ring 22. The assembly ring 22 is provided with a pair of upwardly protruding hollow outer connecting posts 23 and an upwardly protruding lower support post 24. The lower support post 24 is located between the outer connecting posts 23 and its height is lower than that of the outer connecting posts 23. The assembly ring 22, the outer connecting posts 23 and the lower support post 24 are provided with crisscrossing ribs 25. The bottom of the outer connecting post 23 is provided with an opening and connects to the inner connecting post 31 on the anti-slip pad 3. The bottom of the upper ring 1 is provided with an upper support post 15. After the upper ring 1 and the lower ring 2 are fastened together, the upper support post 15 and the lower support post 24 are in contact and connected. Preferably, the ribs 25 pass through the assembly ring 22 and extend beyond the assembly ring 22. During assembly, the anti-slip pad 3 is inserted into the cavity of the outer connecting post 23 through the inner connecting post 31 to form a connecting structure. After the upper ring 1 and the lower ring 2 are fastened together, the upper support post 15 and the lower support post 24 abut against each other to form a support structure between the upper ring 1 and the lower ring 2, preventing them from deforming or sinking.
[0039] Comparison Appendix Figure 5 The upper ring 1 has a front sensor and a rear sensor at its bottom to detect the approach of a human body. The front sensor is located in the front area of the upper ring 1, and the rear sensor is located in the middle area of the upper ring 1. Preferably, the front sensor and the rear sensor are located on the left and right sides of the upper ring 1, respectively. By setting the front and rear sensors, the coverage area of the sensors can be increased, avoiding situations where large-sized toilets cannot detect human bodies, such as when a person is only sitting on the front side of the seat.
[0040] To facilitate sensor installation, the bottom of the upper ring 1 is formed with a front sensor mounting base 16 for installing the front sensor and a rear sensor mounting base 17 for installing the rear sensor.
[0041] Comparison Appendix Figure 6This embodiment also provides a typical ergonomic toilet seat with a curved surface distribution. In this embodiment, the seat has a symmetrical structure. Of course, the curved surface setting can be changed for different people and different seat sizes.
[0042] Appendix Figure 6 The numerical regions in the table correspond to the numbers in Table 1. Table 1 uses the radius of curvature of each region to represent its curvature structure. The positive and negative signs indicate the direction of curvature, and the size of the number indicates the slope of the curvature. The larger the number, the flatter the curvature.
