[0026] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0027] The following is for reference. Figures 1-5 Describes a seat armrest according to an embodiment of the present utility model.

[0028] like Figures 1-5 As shown, the seat armrest includes: armrest frame 1, armrest body 2, connector 3, and rotation locking mechanism.

[0029] The handrail body 2 is positioned above the handrail frame 1. The first end of the connector 3 is rotatably connected to the handrail frame 1, and the second end is rotatably connected to the bottom of the handrail body 2. The handrail body 2 can be horizontally moved to a first position or a second position relative to the handrail frame 1.

[0030] Specifically, the handrail body 2 provides a support surface for the user's elbows. When the user adjusts the forward or backward position of the handrail body 2, moving the handrail body 2 causes the connecting piece 3 to rotate relative to the handrail frame 1. When the connecting piece 3 rotates forward to a certain angle, the handrail body 2 moves horizontally to the first position, that is, the foremost position of the handrail body 2. Figure 4 As shown; when the connecting piece 3 rotates backward to a certain angle, the handrail body 2 moves horizontally to the second position, that is, the final position of the handrail body 2, see Figure 5 As shown, this design meets the user's needs and makes elbow support more comfortable.

[0031] During the movement of the handrail body 2, it remains parallel to the ground; that is, the handrail body 2 does not rotate. Instead, the movement is driven by the rotation of the connecting piece 3, allowing the handrail body 2 to move horizontally to either the first or second position. Furthermore, the projected areas of the handrail body 2 in the first and second positions overlap in the front-to-back direction, with the overlapping portion covering the top of the handrail frame 1.

[0032] Furthermore, the connector 3 can rotate α degrees relative to the handrail frame 1, where α is greater than 0. In this embodiment, α is 180 degrees. Specifically, when the handrail body 2 switches from the first position to the second position, the connector 3 rotates 180 degrees from... Figure 1 The connector 3 shown is flipped to Figure 2 The connector 3 is shown in the diagram.

[0033] Furthermore, the rotation locking mechanism is located between the first end of the connector 3 and the handrail frame 1 and / or between the second end of the connector 3 and the handrail body 2, so that at least one end of the connector 3 can switch between a locked state and an unlocked state.

[0034] With this configuration, the rotation locking mechanism can be located between the first end of the connector 3 and the handrail frame 1. The rotation locking mechanism can lock the connector 3 and the handrail frame 1 to prevent relative rotation, and can also unlock the connector 3 and the handrail frame 1 to allow relative rotation. Similarly, the rotation locking mechanism can be located between the second end of the connector 3 and the handrail body 2 to lock the connector 3 and the handrail body 2 to prevent relative rotation, and can also unlock the connector 3 and the handrail body 2 to allow relative rotation.

[0035] When the handrail body 2 needs to be adjusted forward or backward, the locking mechanism is unlocked by rotating it, allowing the two ends of the connecting piece 3 to rotate. This causes the handrail body 2 to rotate relative to the handrail frame 1, enabling the handrail body 2 to switch from a first position to a second position or vice versa. When the handrail body 2 does not need to be adjusted forward or backward, the locking mechanism locks the rotation between the connecting piece 3 and the handrail frame 1 and / or the handrail body 2, ensuring that the handrail body 2, connecting piece 3, and handrail frame 1 form a stable support structure for users to lean on with their elbows, thus improving safety. When the handrail body 2 needs to be adjusted forward or backward, the locking mechanism is unlocked by rotating it, allowing the two ends of the connecting piece 3 to rotate relative to the handrail frame 1 and the handrail body 2, thus adjusting the position of the handrail body 2.

[0036] In this embodiment, a rotation locking mechanism is provided at the rotational connection point between the handrail body 2 and the connecting member 3. When the rotation locking mechanism locks the handrail body 2 and the connecting member 3, horizontal movement of the handrail body 2 is prevented, ensuring safety. When the rotation locking mechanism unlocks the handrail body 2 and the connecting member 3, the position of the handrail body 2 can be switched.

[0037] According to the present invention, when the armrest body 2 needs to be adjusted in the front-to-back position, the locking mechanism is rotated to unlock it, allowing both ends of the connecting member 3 to rotate, thus enabling the armrest body 2 to switch from a first position to a second position or from a second position to a first position. When the armrest body 2 does not need to be adjusted in the front-to-back position, the locking mechanism is rotated to lock the rotation between the connecting member 3 and the armrest frame 1 and / or the armrest body 2, ensuring that the armrest body 2, the connecting member 3, and the armrest frame 1 form a stable support structure for the user's elbows to lean against, thereby improving safety.

[0038] According to some embodiments of this utility model, the rotation locking mechanism includes a control element 5 that switches at least one end of the connector 3 between a locked state and an unlocked state. With this configuration, the user can switch the unlocked and locked states of the first and / or second ends of the connector 3 by operating the control element 5, which is simple, convenient, and effortless.

[0039] According to some embodiments of the present invention, the rotation locking mechanism includes: a locking member 6, which, in the locked state, is locked between the connecting member 3 and the handrail frame 1; and in the unlocked state, the control element 5 drives the locking member 6 to move to enter one of the connecting member 3 and the handrail frame 1; and / or, the locking member 6 is connected between the connecting member 3 and the handrail body 2, which, in the locked state, is locked between the connecting member 3 and the handrail body 2; and in the unlocked state, the control element 5 drives the locking member 6 to move to enter one of the connecting member 3 and the handrail body 2.

[0040] Understandably, in the locked state, the locking element 6 connects between the connecting element 3 and the handrail frame 1, preventing the connecting element 3 from rotating relative to the handrail frame 1. In the unlocked state, the control element 5 drives the locking element 6 to move into one of the two positions, allowing the connecting element 3 to rotate relative to the handrail frame 1. Similarly, in the locked state, the locking element 6 connects between the connecting element 3 and the handrail body 2, preventing the connecting element 3 from rotating relative to the handrail body 2. In the unlocked state, the control element 5 drives the locking element 6 to move into one of the two positions, allowing the connecting element 3 to rotate relative to the handrail body 2.

[0041] In this embodiment, as Figure 1 As shown, a rotation locking mechanism is provided between the handrail body 2 and the connector 3 to lock or unlock the rotation between the two.

[0042] According to one embodiment of the present invention, one of the connecting member 3 and the handrail body 2 is provided with a sliding groove 7, and the other is provided with a through groove 8. A return spring 9 is provided in the sliding groove 7. A part of the locking member 6 is provided in the sliding groove 7 and abuts against the return spring 9, and the other part is provided in the through groove 8. The control element 5 drives the locking member 6 to move into the sliding groove 7, and the return spring 9 is used to reset the locking member 6 to the locked state.

[0043] See details Figure 3 As shown, since the second end of the connector 3 is placed in the handrail body 2, a sliding groove 7 is provided in the handrail body 2, and a through groove 8 is provided in the connector 3. A portion of the locking member 6 is placed in the sliding groove 7, and another portion is placed in the through groove 8. The end of the locking member 6 placed in the sliding groove 7 away from the through groove 8 abuts against the return spring 9. When the user operates the control element 5, causing the control element 5 to drive the locking member 6 to move completely into the sliding groove 7 through the through groove 8, the handrail body 2 and the connector 3 are unlocked, thereby enabling the front and rear position adjustment of the handrail body 2. When the operation of the control element 5 is canceled, the locking member 6 is reset under the elastic force of the return spring 9, so that a portion of the locking member 6 moves back into the through groove 8.

[0044] Of course, one of the connector 3 and the handrail 1 can be provided with a sliding groove 7, and the other can be provided with a through groove 8. A return spring 9 is provided in the sliding groove 7, and the locking member 6 locks and unlocks between the connector 3 and the handrail 1. This process will not be repeated.

[0045] According to some embodiments of this utility model, the control element 5 is a button. A button is provided at the outer end of the rotatable connection between the connector 3 and the handrail body 2, and the pressing direction of the button is towards the rotation center line of the connector 3.

[0046] Specifically, by pressing the button, the user moves the button towards the rotation center of the connector 3 and the armrest body 2, causing the button to push the locking member 6 into the slide groove 7 through the through groove 8, thereby unlocking the second end of the connector 3.

[0047] The aforementioned rotation locking mechanism effectively unlocks and locks the relative rotation between the handrail body 2 and the connecting piece 3. Its overall structure is simple, and it can be controlled by the movement of the locking piece 6. The design is ingenious. It is also very convenient to operate, requiring only pressing and releasing the button, making it more convenient and labor-saving to use.

[0048] According to another embodiment of the present invention, one of the connecting member 3 and the handrail body 2 is provided with a locking groove, and the other is provided with a through groove 8. The locking member 6 passes through the through groove 8 and locks with the locking groove. The control element 5 drives the locking member 6 to rotate to disengage from the locking groove.

[0049] Specifically, if the handrail body 2 is provided with a locking groove, the connecting member 3 is provided with a through groove 8. The locking member 6 passes through the through groove 8 and locks with the locking groove to achieve a locked state at one end of the connecting member 3. When it is necessary to adjust the front and back position of the handrail body 2, the control element 5 drives the locking member 6 to rotate to release the lock between it and the locking groove. Thus, under the control of the control element 5, it disengages from the locking groove, thereby achieving an unlocked state at one end of the connecting member 3.

[0050] According to some embodiments of this utility model, the control element 5 is a handle. A handle is provided at the outer end of the rotatable connection between the connector 3 and the handrail body 2. The handle is connected to the locking element 6 and is used to make the locking element 6 extend and retract.

[0051] Specifically, the user rotates the locking element 6 by turning the handle, causing it to disengage from the locking groove. The user then extends the locking element 6 out of the locking groove using the handle, thus releasing it. When locking is required, the user inserts the locking element 6 into the locking groove using the handle, engaging it to lock it in place.

[0052] Of course, one of the connector 3 and the handrail 1 can be provided with a locking groove, and the other can be provided with a through groove 8. The locking member 6 can lock and unlock between the connector 3 and the handrail 1. This process will not be repeated.

[0053] According to some embodiments of the present invention, the seat armrest further includes a connecting seat 4, which is installed at the bottom of the armrest body 2, and the second end of the connector 3 is rotatably connected to the connecting seat 4.

[0054] With this configuration, the handrail body 2 is rotatably connected to the second end of the connector 3 via the connecting seat 4, allowing the handrail body 2 to be supported on the connecting seat 4 when switching to the first or second position, further ensuring that the handrail body 2 can move horizontally to the first or second position. The top of the connecting seat 4 is fixed in contact with the bottom of the handrail body 2 to provide support.

[0055] According to some embodiments of this utility model, a rotation locking mechanism is disposed between the connector 3 and the connector 4, allowing at least one end of the connector 3 to switch between a locked state and an unlocked state. That is, the rotation locking mechanism is used to control the locking and unlocking of the connector 3 and the connector 4.

[0056] The seat according to a second aspect of the present invention includes: seat armrests.

[0057] Compared to existing technologies, the armrest of this invention features a locking mechanism that unlocks when the armrest body 2 needs to be adjusted forward or backward, allowing the two ends of the connecting piece 3 to rotate. This enables the armrest body 2 to move horizontally from a first position to a second position or vice versa. When the armrest body 2 does not need to be adjusted forward or backward, the locking mechanism locks the rotation between the connecting piece 3 and the armrest frame 1 and / or the armrest body 2, ensuring a stable structure for the armrest body 2, connecting piece 3, and armrest frame 1, providing a comfortable place for the user's elbows to rest and improving safety.
