Abstract
Description
Technical Field
[0001] The utility model relates to a toilet armrest, in particular to a toilet armrest which can be turned over and folded. Background Art
[0002] Toilet handrails can provide assistance to people with special needs when using the toilet. Handrails can be divided into ordinary handrails and flip-up handrails based on whether they can be flipped up and folded up. Ordinary handrails are fixed and cannot be flipped up. Although the structure is relatively stable, the use of toilets is restricted. Flip-up handrails, on the other hand, can be folded up when not in use, without hindering the general public's use of the toilet. However, when opening, existing flip-up handrails need to be manually supported and slowly lowered. Otherwise, the handrail falling quickly can not only easily hit the user, but also accelerate damage to the handrail itself. In addition, because the flip-up handrail often requires the user to lift and lower it, the gloves on the handrail can easily loosen or even fall off, posing a serious safety hazard to the user. Utility Model Content
[0003] The utility model provides a toilet armrest that can be slowly lowered when flipped open and is safer to use, which overcomes the shortcomings of the background technology. The technical solution adopted by the utility model to solve the technical problem is:
[0004] The toilet armrest comprises a fixing seat, an armrest rod and an armrest cover, the inner end of the armrest rod is directly or indirectly connected to the fixing seat, the armrest cover is sleeved on the outer end of the armrest rod, and further comprises a rotating shaft, a torsion spring and a connecting rod, the rotating shaft is rotatably arranged in the fixing seat, the side wall of the fixing seat is provided with a circumferentially extending arc-shaped clearance hole, the connecting rod passes through the arc-shaped clearance hole to connect the rotating shaft and the armrest rod together, the arc-shaped clearance hole provides space for the connecting rod to make way when the armrest rod is flipped between a horizontal position and a vertical position, one end of the torsion spring is directly or indirectly connected to the rotating shaft, and the other end of the torsion spring is directly or indirectly connected to the fixing seat, the torsion spring applies a torsion force to the rotating shaft to drive the armrest rod to form a rotation trend toward the vertical position, and during the process of the armrest rod leaving the vertical position and flipping toward the horizontal position, the torque generated by the weight of the armrest rod and the armrest cover can overcome the torsion of the torsion spring and slowly fall, and the armrest cover is a double-layer structure, and the hardness of the inner layer is greater than that of the outer layer.
[0005] In a preferred embodiment, the inner layer of the armrest cover is hard plastic, and the outer layer is soft plastic.
[0006] In a preferred embodiment, the inner layer of the armrest cover is PP plastic, and the outer layer is TPE plastic.
[0007] In a preferred embodiment, the outer layer of the armrest cover is connected to the outer surface of the inner layer by injection molding.
[0008] In a preferred embodiment, a connecting piece is further included, the connecting piece is clamped in the fixing seat, a plurality of mounting holes are arranged on the connecting piece at intervals along the circumferential direction, and the other end of the torsion spring is plugged into one of the mounting holes.
[0009] In a preferred embodiment: the rotating shaft is provided with a pillar, the torsion spring is sleeved on the pillar, the end face of the pillar is provided with a circular boss, the connecting piece can be relatively rotatably sleeved on the boss, and also includes a baffle, the baffle clamps the connecting piece in the axial direction, and the bolt passes through the baffle and is screwed to the pillar.
[0010] In a preferred embodiment, a positioning groove is provided on the inner wall of the fixing seat, and a positioning terminal is provided on the end surface of the connecting rod. When the connecting rod rotates to a vertical position, the positioning terminal is embedded in the positioning groove.
[0011] In a preferred embodiment, the positioning terminal is an elastic floating member, the connecting rod is provided with a receiving hole, the inner end of the positioning terminal is inserted into the receiving hole, and a spring is tensioned between the positioning terminal and the connecting rod.
[0012] In a preferred embodiment, the connecting rod and the rotating shaft are locked together by bolts, and the connecting rod and the handrail are locked together by bolts.
[0013] In a preferred embodiment, a decorative cover is further included, which covers the position where the connecting rod is connected to the handrail rod and covers the arc-shaped clearance hole at the same time.
[0014] Compared with the background technology, this technical solution has the following advantages:
[0015] 1. When the handrail is lowered, it is blocked by the torsion force of the torsion spring, forming a buffering effect, so that the handrail falls slowly, thereby preventing the handrail from falling freely and quickly. On the contrary, when the handrail is folded up, the torsion force of the torsion spring provides assistance, which is more labor-saving.
[0016] 2. The handrail cover adopts a double-layer structure. The inner layer is harder than the outer layer. The outer layer is soft and meets the requirements for the use of the handrail cover. The inner layer has high hardness and is more firmly attached to the handrail rod, preventing the handrail cover from loosening and making it safer and more reliable to use.
[0017] 3. Several mounting holes are provided at intervals along the circumference of the connecting piece. If no mounting holes are provided, the torsion of the torsion spring can be adjusted.
[0018] 4. The baffle limits the torsion spring. During assembly, the rotating shaft, torsion spring, and baffle can be pre-assembled together and then placed together in the fixed seat for easy assembly.
[0019] 5. When the handrail is in the vertical position, the positioning terminal is embedded in the positioning groove to prevent the handrail from falling accidentally. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Please refer to Figures 1 to 9The toilet handrail includes a fixed seat 10, a handrail rod 20 and an handrail cover 30. The inner end of the handrail rod 20 is directly or indirectly connected to the fixed seat 10, and the handrail cover 30 is sleeved on the outer end of the handrail rod 20. The fixed seat can be fixedly connected to components such as a cabinet, a toilet or a wall. It also includes a rotating shaft 40, a torsion spring 50 and a connecting rod 60. The rotating shaft 40 is rotatably arranged in the fixed seat 10. The side wall of the fixed seat 10 is provided with a circumferentially extending arc-shaped clearance hole 12. The connecting rod 60 passes through the arc-shaped clearance hole 12 to connect the rotating shaft 40 with the handrail rod 20. The arc-shaped clearance hole 12 provides space for the connecting rod 60 to make way when the handrail rod 20 is flipped between the horizontal position and the vertical position, that is, the connecting rod will not interfere with the fixed seat during the flipping process. One end of the torsion spring 50 is directly or indirectly connected to the rotating shaft 40, and the other end of the torsion spring is directly or indirectly connected to the fixing base 10. The torsion spring 50 applies a torsional force to the rotating shaft 40, which drives the handrail 20 to form a rotational tendency toward the vertical position. In other words, the elastic force generated by the torsion spring acts on the rotating shaft in the same direction as the handrail is tilted toward the vertical position. Therefore, if the handrail is to be opened, the torsion force of the torsion spring must be overcome. At the same time, when the handrail 20 leaves the vertical position and tilts toward the horizontal position, the torque generated by the weight of the handrail 20 and the handrail cover 30 can overcome the torsion force of the torsion spring 50 and slowly fall.
[0031] Preferably, the armrest cover 30 has a double-layer structure, with the inner layer 32 having a greater hardness than the outer layer 34. Further preferably, the inner layer 32 of the armrest cover 30 is made of hard plastic, while the outer layer 34 is made of soft plastic. In this embodiment, the inner layer of the armrest cover is made of PP plastic, and the outer layer is made of TPE plastic. Furthermore, the outer layer of the armrest cover is connected to the outer surface of the inner layer by injection molding.
[0032] Preferably, the device further includes a connecting piece 70 that is snap-fitted into the fixing base 10. The connecting piece 70 is provided with a plurality of mounting holes 72 spaced circumferentially thereon, with the other end of the torsion spring 50 plugging into one of these mounting holes. In other words, the torsion spring 50 is connected to the fixing base 10 via the connecting piece 70, and different mounting holes can adjust the degree of deformation of the torsion spring, thereby adjusting the torsion spring's torsional force.
[0033] Preferably, the rotating shaft 40 is provided with a support 42, and the torsion spring 50 is mounted on the support 42. The end surface of the support 42 is provided with a circular boss 44, and the connecting piece 70 is relatively rotatably mounted on the boss 44. The rotating shaft 40 further includes a retaining plate 80, which axially retains the connecting piece 70. A bolt passes through the retaining plate and is screwed onto the support 42. Thus, the retaining plate 80 and the end surface of the support 42 retain the connecting piece 70 from both sides, and the connecting piece 70 is in turn engaged with the fixing seat 10. Thus, when the rotating shaft 40 rotates, the support 42 can rotate relative to the connecting piece 70, thereby twisting the torsion spring 50.
[0034] Preferably, a positioning groove 14 is provided on the inner wall of the fixing base 10, and a positioning terminal 62 is provided on the end surface of the connecting rod 60. When the connecting rod 60 is rotated to a vertical position, the positioning terminal 62 engages with the positioning groove 14, thereby providing a retaining force for the connecting rod 60 and preventing the handrail from accidentally falling. Further preferably, the positioning terminal 62 is an elastic floating member. Specifically, the connecting rod 60 is provided with a receiving hole, the inner end of the positioning terminal 62 is inserted into the receiving hole, and a spring 64 is tensioned between the positioning terminal 62 and the connecting rod 60. Therefore, under the action of the spring 64, the positioning terminal 62 can extend and retract along the receiving hole.
[0035] Preferably, the connecting rod 60 and the rotating shaft 40 are locked together by bolts, and the connecting rod 60 and the handrail rod 20 are locked together by bolts.
[0036] Preferably, a decorative cover 90 is further included, which covers the position where the connecting rod 60 is connected to the handrail rod 30 and covers the arc-shaped clearance hole 12 at the same time.
[0037] The above description is merely a preferred embodiment of the present invention and therefore cannot be used to limit the scope of implementation of the present invention. In other words, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope of the present invention.
