Description

Technical Field

[0001] The utility model relates to the field of bathroom products, in particular to a toilet handrail frame structure. Background Art

[0002] The toilet handrail is a device used to assist in standing up and squatting when using the toilet, so as to solve the problem that it is difficult for the elderly and disabled to stand up when using the toilet. For example, the Chinese patent literature discloses a technical solution with a patent application number of 202322209763.4 and the name of "a combined toilet handrail", which mainly includes a support frame in the shape of the letter H, and an armrest assembly arranged on the support frame. The armrest assembly includes a support crossbar, a connecting rod, a holding crossbar, and a vertical adjustment rod. The front end of the holding crossbar is connected to the front end of the support crossbar through a connecting rod, and the support crossbar is located above the holding crossbar. The rear end of the support crossbar is connected to the upper end of the vertical adjustment rod, and the vertical adjustment rod is plugged and connected to the support frame. When in use, the hand holds the holding crossbar as a force point to stand up, and the forearm contacts the support crossbar as an auxiliary fulcrum to form a support, thereby assisting the elderly and disabled to stand up quickly. However, in actual application, the toilet handrail still has the following shortcomings:

[0003] Since the holding cross bar is connected to the vertical adjustment rod through the connecting rod and the supporting cross bar, when you stand up with the holding cross bar as the force point, it is equivalent to using the front end of the supporting cross bar as the force point. It will be similar to the principle of a lever, and the connection between the supporting cross bar and the vertical adjustment rod can be easily pried, making it very easy to bend and deform at the connection, resulting in poor reliability of its supporting load-bearing capacity. In severe cases, the connection may also break, causing the user to fall. There are certain safety hazards. The structural design of this type of toilet armrest is very unreasonable.

[0004] Therefore, in view of the aforementioned deficiencies of this type of toilet handrail, it is very necessary to redesign its structure to better meet people's application needs. Utility Model Content

In addition, the second-level handrail, as an auxiliary support point, is subjected to less force, and is not easy to bend and deform or break even if it is only connected to the rear vertical rod. At the same time, the front end of the second-level handrail is not connected to the front end of the first-level handrail, so as to form an open space for the user's hand movement, and will not excessively limit the user's hand movement range, so as to enhance the user's use experience.

[0022] like Figure 1 and Figure 2 As shown, a toilet handrail frame structure described in the utility model comprises a support frame 1, wherein the support frame 1 comprises a front vertical rod 11 and a rear vertical rod 12, wherein the upper end of the front vertical rod 11 is provided with a first-stage handrail rod 13 extending backward and connected to the upper end of the rear vertical rod 12, and a connecting rod 14 located below the first-stage handrail rod 13 is also connected between the front vertical rod 11 and the rear vertical rod 12, so that the front vertical rod 11, the first-stage handrail rod 13, the rear vertical rod 12 and the connecting rod 14 are connected to form a support frame structure in the shape of the letter A; the upper end of the rear vertical rod 12 is also provided with a second-stage handrail rod 15 extending forward, and the second-stage handrail rod 15 is located above the first-stage handrail rod 13. When the utility model stands up with the first-stage handrail rod 13 as the force point, the force it receives will be dispersed to the front vertical rod 11 and the rear vertical rod 12 respectively, so that it can obtain better support and load-bearing performance, is not easy to bend and deform, and is not easy to break, eliminates safety hazards, and has higher reliability in use. Moreover, the second-stage handrail 15 is an auxiliary support point, and the force it receives is small, so even if it is only connected to the rear vertical rod, it is not easy to bend, deform, or break. At the same time, the front end of the second-stage handrail 15 is not connected to the front end of the first-stage handrail 13, so as to form an open space for the user's hand to move, and the user's hand movement range will not be excessively restricted, so as to improve the user's use experience.

[0023] like Figure 2 As shown, the first-stage handrail 13 is a diagonal bar structure arranged from front to back and tilted upward. This not only makes the activity space between the first-stage handrail 13 and the second-stage handrail 15 larger, but also the tilted first-stage handrail 13 is more in line with the posture of people holding their hands when sitting, making it easier to exert force, so that people can quickly and easily get up with the help of the first-stage handrail 13.

[0024] In order to improve the overall stability of the support frame 1, Figure 2 As shown, the front vertical rod 11 and the rear vertical rod 12 are arranged in an eight-shaped shape, that is, the distance between the lower ends of the front vertical rod 11 and the rear vertical rod 12 is greater than the distance between the upper ends of the front vertical rod 11 and the rear vertical rod 12. In this way, the support frame 1 can form a stable triangular support structure, thereby making the overall stability of the support frame 1 better and less likely to loosen.

[0025] In order to make holding or leaning on the first-stage handrail 13 and the second-stage handrail 15 more comfortable, Figure 2 As shown, the first-stage handrail bar 13 and the second-stage handrail bar 15 are respectively provided with a pad 2. In actual application, the support frame 1 can be made of plastic or metal, and the metal can be made of stainless steel or iron. The pad 2 can be made of plastic or a sponge pad.

[0026] In actual application, a support frame 1 can be used to form the toilet handrail frame of the utility model. When a support frame 1 is used, the bottom ends of the front vertical rod 11 and the rear vertical rod 12 are locked on the ground by screws to ensure the stability and reliability of use.

[0027] Of course, two support frames 1 can also be used to form the toilet handrail frame of the utility model, such as Figure 1 As shown, there are two support frames 1, and the two support frames 1 are arranged at intervals on the left and right sides. Through such a structural design, the two support frames 1 can be respectively arranged on the left and right sides of the toilet, so that people can use both hands to help get up, so that getting up is easier.

[0028] In order to make the two support frames 1 firmly connected together, so that the two support frames 1 can be installed on both sides of the toilet at the same time and not easily loose, Figure 1 As shown, the utility model further comprises a cross bar 3, and the front vertical bars 11 of the two support frames 1 are respectively connected together by the cross bar 3. In this way, the two support frames 1 can be moved from the front side of the toilet to the left and right sides of the toilet together.

[0029] In order to ensure that the toilet handrail structure can be firmly installed on the toilet without loosening, so as to ensure the reliability and safety of use, Figure 3As shown, the connecting rods 14 of the two support frames 1 are respectively provided with clamping mechanisms 4; the connecting rods 14 are provided with threaded through holes 141, and the clamping mechanisms 4 include a top tightening portion 41, a threaded rod 42, a handle portion 43, and a universal joint connection portion 44.
