These errors can cause significant deviations between the initial position and the raised position of the grab bar after installation and the original design requirements. This deviation not only affects the product's aesthetics but may also impact the user experience. For example, if the initial position of the grab bar is too far forward or backward, it may cause inconvenience for the user and even increase the risk of falls. Therefore, how to address this issue in the design, enabling the grab bar to adapt to the manufacturing errors of different toilets, has become a direction that requires attention and improvement.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0027] Example 1

The armrest body 3 is rotatable relative to the fixing component. It also includes an adjustment surface 4 on the fixing component and an angle adjustment component on the armrest body 3. By adjusting the position of the adjustment surface and / or the angle adjustment component, the contact position between the angle adjustment component and the adjustment surface 4 can be adjusted. By providing an angle adjustment component on the armrest body 3 and an adjustment surface 4 on the fixing component to cooperate with it, the contact position between the angle adjustment component and the adjustment surface can be adjusted by adjusting the adjustment surface and / or the adjustment surface, thereby achieving adjustment of the armrest's limiting position. This effectively meets the usage requirements of the armrest's initial and raised positions, ensuring both product functionality and aesthetics. The user device can be a toilet or a shower chair, etc., but is not limited to these.

[0029] Please see Figures 1 to 6 Preferably, the fixing component includes a handrail pivot 2, and the handrail body 3 is pivotally connected to the handrail pivot 2. The handrail body 3 is rotatable relative to the handrail pivot 2. The adjustment surface 4 is disposed on the circumferential surface of the handrail pivot 2. The angle adjustment component includes a stop member 5 passing through the handrail body 3. The stop member 5 can abut against the adjustment surface 4. The stop member 5 can extend and retract relative to the handrail body 3 to change the distance between it and the adjustment surface of the handrail pivot 2. By extending and retracting the stop member 5 relative to the handrail body 3, the relative contact position between the stop member 5 and the adjustment surface 4 can be changed, thereby adjusting the handrail's lowered position and raised limit position.

[0030] Please see Figures 1 to 6 Preferably, the handrail body 3 includes a handrail mounting base 31 and a handrail side rod 32. The handrail side rod 32 is fixedly connected to the handrail mounting base 31. The handrail mounting base 31 is provided with a pivot hole 311. The handrail pivot 2 passes through the pivot hole 311, allowing the handrail mounting base 31 to rotate relative to the handrail pivot 2. The handrail mounting base 31 is provided with an adjustment hole 312. One end of the adjustment hole 312 is connected to the pivot hole 311. The abutment 5 passes through the adjustment hole 312 and rotates with the handrail mounting base 31 around the handrail pivot 2. The top abutment 5 is inserted into the adjustment hole 312 of the handrail mounting base 31 and rotates with the handrail mounting base. The contact position between the top abutment 5 and the adjustment surface 4 can be adjusted by extending and retracting the top abutment 5 in the adjustment hole 312. That is, by adjusting the amount of the top abutment 5 extending into the pivot hole 311, the initial and lifting limit positions of the handrail can be adjusted.

[0031] Please see Figures 1 to 6Preferably, there is one abutment 5 and several adjustment holes 312, the number of adjustment holes 312 being greater than or equal to the number of abutment 5; or, there are two or more abutment 5 and two or more adjustment holes 312, the number of adjustment holes 312 being greater than or equal to the number of abutment 5; at least two of the adjustment holes 312 contain the abutment 5, and the two abutment 5 respectively abut against the adjustment surfaces 4 on both sides of the axis of the armrest pivot 2. Having one or more abutment 5 and several adjustment holes 312 allows for adjustment of the other adjustment holes 312 of the abutment 5 according to actual needs, enabling extension and retraction within different adjustment holes 312, providing a more flexible adjustment strategy and higher adjustment precision. In this embodiment, there are two abutment 5 and two adjustment holes 312.

[0032] Please see Figures 1 to 6 Preferably, the adjusting hole 312 is a threaded hole, and the abutment 5 is an adjusting bolt, which passes through the threaded hole. The adjusting hole 312 is a threaded hole, and the abutment 5 is an adjusting bolt. By rotating the adjusting bolt, the relative extension and retraction of the armrest mounting base 31 can be achieved, changing the contact position with the adjusting surface 4, thus easily changing the limiting angle.

[0033] Please see Figures 1 to 6 Preferably, the adjustment surface 4 includes a first contact surface 41 and a second contact surface 42. When the handrail body 3 is in the lowered state, the angle adjustment component contacts the first contact surface 41; when the handrail body 3 is in the raised state, the angle adjustment component contacts the second contact surface 42. Having two contact surfaces, in the lowered state, the angle adjustment component abuts against the first contact surface 41; in the raised state, the angle adjustment component abuts against the second contact surface 42. Adjusting the contact position between the angle adjustment component and the first contact surface 41 adjusts the limiting angle of the handrail in the lowered state, and adjusting the contact position between the angle adjustment component and the second contact surface 42 adjusts the limiting angle of the handrail in the raised state.

[0034] Please see Figures 1 to 6Preferably, the handrail body 3 includes a handrail mounting base 31, the handrail mounting base 31 is provided with a pivot hole 311, the fixing component includes a handrail pivot 2, the handrail pivot 2 passes through the pivot hole 311 so that the handrail mounting base 31 can rotate relative to the handrail pivot 2, a transition surface 43 is provided between the first contact surface 41 and the second contact surface 42, the second contact surface 42, the transition surface 43 and the first contact surface 41 are sequentially connected, the two ends of the axis of the handrail pivot 2 slide against the inner arc surface of the pivot hole 311, the length of the inner arc surface of the pivot hole 311 between the two ends of the axis of the handrail pivot 2 is greater than the length of the adjustment surface formed by the sequential connection of the second contact surface 42, the transition surface 43 and the first contact surface 41 between the two ends of the axis of the handrail pivot 2, and the second contact surface 42 is an inclined surface. On the circumference of the armrest pivot 2, the first contact surface 41 and the second contact surface 42 are directly provided with a transition surface 43 to avoid interfering with the rotation of the armrest, that is, to avoid blocking the abutment 5. The first contact surface 41 and the second contact surface 42 can be inclined surfaces or curved surfaces, and the transition surface 43 can also be curved surfaces or inclined surfaces, as long as it does not interfere with the movement of the abutment 5. An adjustment surface 4 can be provided on both sides of the armrest pivot, and each adjustment surface 4 has a first contact surface 41, a second contact surface 42 and a transition surface 43. The armrest mounting base 31 is provided with two adjustment holes 312 on both sides of the pivot hole 311, and the abutment 5 passes through the two adjustment holes 312 on one side; in the initial state, the lower abutment 5 abuts against the first contact surface 41, and in the raised state, the upper abutment 5 abuts against the second contact surface 42. The left and right sides of the handrail pivot 2 are provided with adjustment surfaces 4, and the corresponding positions of the side walls of the pivot hole 311 of the handrail mounting base 31 are provided with adjustment holes 312, so as to facilitate the flexible adjustment of the installation position of the top abutment 5 according to the installation needs. In this embodiment, the second contact surface 42 is an inclined surface so that when the top abutment 5 rotates with the handrail mounting base 31 and the second contact surface 42, the second contact surface 42 can better abut against the handrail and position it.

[0035] Please see Figures 1 to 6Preferably, the handrail body 3 further includes a first washer 33, which is locked to the end of the handrail pivot 2 opposite to the user device 1 to lock the handrail mounting base 31 and the handrail pivot 2. The size of the first washer 33 is larger than the size of the pivot hole 311. The handrail mounting base 31 is provided with a locking hole, and a locking bolt 6 passes through the locking hole. The locking bolt 6 passes through the handrail side rod 32 to lock the handrail mounting base 31 and the handrail side rod 32. The locking hole communicates with the pivot hole 311. The handrail mounting base 31, which is located opposite to the pivot hole 311, has a clearance hole to allow the locking bolt 6 to pass through. The first washer 33 facilitates the positioning of the handrail mounting base 31 on the handrail pivot 2. The handrail body 3 is designed as a separate structure of handrail mounting base 31 and handrail side bar 32, which are connected by locking bolts 6 on both sides, making it convenient to maintain the handrail mounting base 31 and handrail side bar 32 separately.

[0036] Please see Figures 5 to 6 Preferably, a first friction plate 34 is provided between the handrail mounting base 31 and the first gasket 33; a second gasket 35 and a second friction plate 36 are provided on the handrail pivot 2, the second gasket 35 and the second friction plate 36 being located between the end face of the handrail pivot 2 and the handrail mounting base 31 near the user device 1 and the handrail pivot 2; a decorative cover fixing bracket 37 is fitted on the handrail mounting base 31, a decorative cover 38 is fitted on the decorative cover fixing bracket 37, and a clearance hole 371 is provided on the decorative cover fixing bracket 37 opposite to the adjustment hole 312; a clearance groove 372 is provided on the decorative cover fixing bracket 37 at the position opposite to the handrail side rod 32 and the clearance hole. The first friction plate 34 and the second friction plate 36 can increase the service life of the product. The decorative cover 38 helps improve the aesthetics. The clearance hole 371 facilitates the adjustment of the top abutment 5, and the clearance groove 372 facilitates the adjustment of the locking bolt 6.

[0037] This embodiment has the following working principle:

[0038] When adjusting the limit position of the lowered state, the adjusting bolt in the adjusting hole 312 on the lower right side of the handrail mounting base 31 presses against the initial position on the handrail shaft 2 (i.e., the contact position between the lower adjusting bolt and the first contact surface 41). By rotating the adjusting bolt, the adjusting bolt extends and retracts in the adjusting hole 312, thereby changing its distance from the axis of the handrail shaft 2, and thus changing the contact position with the first contact surface 41, achieving the adjustment of the initial position limit angle of the handrail. For example, if the length of the adjusting bolt extending into the shaft hole 311 is increased, when the handrail body 3 is rotated to the initial state, the adjusting bolt will contact the first contact surface 41 earlier than before (i.e., the contact position between the adjusting bolt and the first contact surface 41 is closer to the transition surface 43), thereby preventing the handrail body 3 from rotating further, that is, the range of rotation of the handrail body 3 becomes smaller. Conversely, if the length is increased, the contact with the first contact surface 41 is delayed (i.e., the contact position between the adjusting bolt and the first contact surface 41 is further away from the transition surface 43), and the range of rotation becomes larger.

[0039] When adjusting the limit position of the raised state, the adjusting bolt in the adjusting hole 312 on the upper right side of the adjusting seat 31 of the handrail presses against the initial position on the handrail shaft 2 (i.e., the contact position between the upper adjusting bolt and the second contact surface 42). By rotating the adjusting bolt, the adjusting bolt extends and retracts in the adjusting hole 312, thereby changing its distance from the axis of the handrail shaft 2, and thus changing the contact position with the second contact surface 42, thereby adjusting the limit angle of the raised position of the handrail. For example, if the length of the adjusting bolt extending into the shaft hole 311 is increased, when the handrail body 3 is rotated to the raised state, the adjusting bolt will contact the second contact surface 42 earlier than before (i.e., the contact position between the adjusting bolt and the second contact surface 42 is closer to the transition surface 43), thus preventing the handrail body 3 from rotating further, that is, the range of rotation of the handrail body 3 becomes smaller. Conversely, if the length of the adjusting bolt is increased, the contact with the second contact surface 42 will be delayed (i.e., the contact position between the adjusting bolt and the second contact surface 42 is further away from the transition surface 43), and the range of rotation becomes larger. This solution allows for stepless adjustment of the armrest limit position.

[0040] Implementation 2

[0041] In another embodiment, the difference from Embodiment 1 is that: the handrail body 3 includes a handrail connecting seat and a handrail side rod 32, the handrail side rod 32 is fixedly connected to the handrail connecting seat, the handrail connecting seat is provided with a pivot hole, the fixing component includes a handrail pivot 2 and a pivot fixing seat, the handrail pivot 2 is mounted on the user device through the pivot fixing seat, the handrail pivot 2 passes through the pivot hole so that the handrail connecting seat can rotate relative to the handrail pivot 2, the angle adjustment component includes a top abutment, the top abutment rotates with the handrail connecting seat around the handrail pivot 2 and abuts against the adjustment surface of the pivot fixing seat; the top abutment passes through the handrail connecting seat and extends and retracts radially along the handrail connecting seat, or the top abutment is provided inside the handrail connecting seat and slides radially along the handrail connecting seat.

[0042] Specifically, the rotation axis of the handrail connecting seat may be offset from its central axis; the abutment may be an abutment bolt, which passes through the adjustment hole provided in the handrail connecting seat, and the end face of the abutment bolt may abut against the adjustment surface on the outer circumference of the rotating shaft fixing seat, and the path of the abutment bolt rotating relative to the rotating shaft may intersect with the adjustment surface. Alternatively, the rotation axis of the armrest connecting seat may be offset from its central axis; the abutment is a sliding protrusion provided at the position opposite to the rotating shaft fixing seat of the armrest connecting seat. The sliding protrusion can slide on the guide groove provided on the armrest connecting seat, the guide groove is provided along the radial direction of the armrest connecting seat, and the sliding protrusion is slidably installed in the guide groove. A stop is provided in the guide groove to fix the sliding protrusion in the guide groove. The stop can be a screw, etc., to lock the sliding protrusion in the guide groove. The trajectory of the sliding protrusion as the connecting seat rotates can intersect the adjustment surface of the rotating shaft fixing seat; or, the guide groove can be provided along the circumference of the armrest connecting seat, and the armrest connecting seat and the rotating shaft fixing seat are eccentrically connected. The mating surface between the sliding protrusion and the adjustment surface is a curved surface or an inclined surface, and the overall cross-section of the sliding protrusion is trapezoidal or triangular.

[0043] Preferably, the handrail connecting seat can be a component consisting of the handrail mounting seat and the decorative cover fixing frame in embodiment one; of course, it can also be a sleeve fitted on the pivot fixing seat, or a tubular tube, etc., and is not limited thereto; when the abutting member is an abutting bolt, it is inserted through its circumference.

[0044] Preferably, at least two abutment members are provided and arranged at intervals around the circumference of the rotating shaft fixing seat.

[0045] This embodiment has the following working principle:

[0046] When the abutment is a abutment bolt, rotating the abutment bolt moves it away from the rotating shaft fixing seat. This delays the contact point between the abutment bolt and the adjusting surface of the rotating shaft fixing seat, thus increasing the rotation range of the handrail connecting seat. Conversely, moving the contact point forward reduces the rotation range of the handrail connecting seat, thereby adjusting the lifting and lowering angles. The two abutment components are used for adjusting the lifting angle and the lowering angle, respectively.

[0047] The top abutment is a sliding protrusion. When the guide groove is in the radial direction, the sliding protrusion moves towards the direction close to the rotating shaft fixed seat, which can delay the contact point between the contact surface of the sliding protrusion and the adjustment surface, thereby increasing the rotation range of the handrail connecting seat. Conversely, the contact point is advanced, and the rotation range of the handrail connecting seat is reduced, thus realizing the adjustment of the lifting and lowering angles. After the angle adjustment is completed, it is locked by the stop. The two top abutments are used for the angle adjustment of the lifting position and the angle adjustment of the lowering position, respectively.

[0048] The top abutment is a sliding protrusion. When the guide groove is in the circumferential direction, the guide groove is located on the side of the rotating shaft fixing seat near the center of the handrail connecting seat. Moving the sliding protrusion along the guide groove closer to the center of the handrail connecting seat can delay the contact point between the contact surface of the sliding protrusion and the adjustment surface, thus increasing the rotation range of the handrail connecting seat. Conversely, moving the contact point forward will reduce the rotation range of the handrail connecting seat, thereby adjusting the lifting and lowering angles. After the angle adjustment is completed, it is locked by the stop. The two top abutments are used for adjusting the angle of the lifting position and the angle of the lowering position, respectively.

[0049] Another toilet is provided, which is equipped with a handrail angle adjustment device as described in any of the above.

[0050] Several points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection.
