Description

Technical Field

[0001] This utility model relates to the field of seating technology, and in particular to an armrest assembly and a seat. Background Technology

[0002] Chairs are commonly seen in offices, study rooms, and other similar spaces, meeting people's needs for sitting while working, studying, or resting. Generally, a chair consists of a base, backrest, seat cushion, and armrests. When using a chair, people can naturally place their arms on the armrests, which provide support.

[0003] In related technologies, armrests provide support to users in fixed positions. Due to differences in body shape, larger individuals may feel cramped when sitting in the chair because of the fixed position of the armrests, which feel close together and can create a feeling of being squeezed. On the other hand, smaller individuals may feel spacious when sitting in the chair because the armrests are far apart, making it difficult to place their arms naturally on the armrests, thus affecting seating comfort. Utility Model Content

[0004] The main purpose of this utility model is to provide an armrest assembly that, to a certain extent, enables the armrests of a seat to adapt to users of different body types and provide them with good support.

[0005] To achieve the above objectives, this utility model proposes an armrest assembly for use in a seat, the seat including a mounting bracket, wherein the armrest assembly includes:

[0006] The handrail has a connecting portion rotatably connected to the mounting frame, and the handrail can rotate outward or inward as the connecting portion rotates relative to the mounting frame.

[0039] This utility model embodiment proposes an armrest assembly 100 for use in a seat. In addition to the armrest assembly 100, the seat also includes a base 200, a seat cushion 300, and a backrest 400. The seat cushion 300 is disposed on the base 200 for use by a user, providing support for the user's buttocks and thighs. The backrest 400 is disposed behind the seat cushion 300 and connected to the base 200, providing support for the user's back and waist. Figure 1 As shown, when the armrest assembly 100 is applied to the seat, there can be two armrest assemblies 100. The two armrest assemblies 100 are respectively arranged on the left and right sides of the seat cushion 300 to provide support for the user's left and right arms respectively.

[0040] Among them, such as Figure 2 As shown, the seat includes a mounting frame 500, which is a frame structure within the seat. This mounting frame 500 can be located within the seat cushion 300, serving as the skeleton of the seat cushion 300; or it can be located on the base 200, serving as the structural frame of the base 200; or it can be located between the base 200 and the seat cushion 300, serving as a frame for mounting seat components (such as the armrest assembly 100). The aforementioned placement and corresponding functions of the mounting frame 500 are merely illustrative and not limiting; other configurations are also possible, which will not be detailed here.

[0041] Reference Figure 1 and Figure 2 The armrest assembly 100 includes:

[0042] The handrail 110 has a connecting part 111, which is rotatably connected to the mounting frame 500. The handrail can rotate outward or inward as the connecting part 111 rotates relative to the mounting frame 500.

[0043] Locking module 120, connecting mounting bracket 500, the locking module 120 is disposed on the periphery of the connecting part 111, and is used to lock the connecting part 111.

[0044] The armrest assembly 100 involved in this embodiment is disposed on the seat mounting frame 500. The armrest 110 has a shape generally similar to a conventional armrest. The armrest 110 has a support portion at its top for providing support for the user's arm, and a connecting portion 111 at its bottom. The armrest 110 is connected to the mounting frame 500 via its connecting portion 111, enabling rotatable mounting on the mounting frame 500. Specifically, the connecting portion 111 is rotatably connected to the mounting frame 500, and the armrest 110 can rotate as its connecting portion 111 rotates relative to the mounting frame 500. The rotation of the armrest 110 includes rotation towards the outward direction and rotation towards the inward direction. When the armrest 110 rotates towards the outward direction, its distance from the center of the seat gradually increases; conversely, when the armrest 110 rotates towards the inward direction, its distance from the center of the seat gradually decreases. Taking the scenario of a user sitting in a seat as an example, the armrest 110 rotates outward, that is, the armrest 110 rotates away from the user, which can increase the distance between the armrest 110 and the user. Correspondingly, the armrest 110 rotates inward, that is, the armrest 110 rotates closer to the user, which can reduce the distance between the armrest 110 and the user.

[0045] The connecting part 111 is rotatably connected to the mounting bracket 500, and the arrangement can include various forms, such as:

[0046] Firstly, the connecting part 111 is provided with a shaft hole, and the mounting bracket 500 is provided with a mounting shaft. The connecting part 111 is sleeved on the mounting shaft through the shaft hole and can rotate relative to the mounting shaft, thereby rotatably connecting the mounting bracket 500. Secondly, the mounting bracket 500 is provided with a rotating shaft, and the connecting part 111 is connected to the rotating shaft, thereby rotatably connecting the mounting bracket 500. Of course, the above are merely exemplary and not restrictive; other configurations are also possible.

[0047] Based on the mounting position of the connecting portion 111 of the handrail 110 on the mounting bracket 500, the locking module 120 is correspondingly disposed on the mounting bracket 500 and located around the connecting portion 111. When the handrail 110 is turned to adjust its angle / position, the handrail 110 rotates based on the rotation of the connecting portion 111, and the relative position of the connecting portion 111 and the locking module 120 changes. The locking module 120 can lock the connecting portion 111, thereby positioning the handrail 110 so that the handrail 110 is maintained at the adjusted angle / position. The locking mechanism of the locking module 120 can take various forms. For example, the locking module 120 can lock the connecting part 111 by pressing against the outer wall of the connecting part 111; or, the outer wall of the connecting part 111 has a groove, and the locking module 120 can lock the connecting part 111 by engaging the groove of the connecting part 111; or, a magnetic attraction structure can be provided between the locking module 120 and the connecting part 111, and the locking module 120 can lock the connecting part 111 by magnetically engaging with the connecting part 111. The locking mechanisms of the locking module 120 mentioned above are merely exemplary and not limiting, and include but are not limited to these.

[0048] The working principle of the handrail assembly 100 is as follows:

[0049] The armrest 110 can be rotated outwards or inwards via the connecting part 111 on the mounting bracket 500 to adjust its angle / position. After adjusting to the desired angle / position, the locking module 120 locks the connecting part 111 accordingly. Therefore, when riding, the user can adjust the armrest 110 outwards or inwards to a suitable position according to their body shape, so that the armrest 110 can provide good support for the user's arms, thereby improving riding comfort.

[0050] This utility model provides an innovative handrail assembly 100. By utilizing the rotatable characteristic of the handrail 110 in combination with a unique locking module 120, the handrail 110 can be adjusted in multiple angles / positions in a convenient and precise manner, ensuring that users of different body types can obtain ideal arm support and improving user comfort. At the same time, the structure and connection method of the locking module 120 are optimized to ensure a smooth and stable adjustment process, thereby enhancing the reliability and durability of the overall device.

[0051] In some embodiments, refer to Figures 3 to 5 The locking module 120 includes:

[0052] Locking component 121;

[0053] The locking member 121 and the connecting part 111 are provided with a buckle 10 and a plurality of slots 20. The plurality of slots 20 are spaced apart along the rotation direction of the connecting part 111. The buckle 10 is used to engage with one of the slots 20 to lock the connecting part 111.

[0054] The locking element 121 of the locking module 120 and the connecting part 111 are locked together by a snap-fit ​​10 and a slot 20. The locking element 121 may have a snap-fit ​​10, and the connecting part 111 may have multiple slots 20; alternatively, the connecting part 111 may have a snap-fit ​​10, and the locking element 121 may have multiple slots 20, depending on the specific requirements. The multiple slots 20 are arranged sequentially and spaced apart along the rotation direction of the connecting part 111. The snap-fit ​​10 is positioned opposite to the multiple slots 20, and the snap-fit ​​10 is used to lock the connecting part 111 by snapping into one of the slots 20.

[0055] The multiple slots 20 correspond to different angle / position settings of the armrest 110. During adjustment of the armrest 110, as the angle / position changes, the different slots 20 sequentially align with the latches 10. When the armrest 110 is adjusted to the desired angle / position, the latches 10 engage with the corresponding slots 20, and the locking connection 111 positions the armrest 110. The structure is simple and easy to operate. It is easy to understand that, in application, the adjustable angle range of the armrest 110 can be controlled by setting the number and position of the slots 20. Furthermore, the spacing between any two adjacent slots 20 is the same; the angle change of the armrest 110 in a single movement can be controlled by setting the spacing between adjacent slots 20.

[0056] In some embodiments, refer to Figures 4 to 7 The locking element 121 is provided with a buckle 10;

[0057] The connecting part 111 is provided with a mating part 112 that is opposite to the position of the buckle 10, and the mating part 112 is provided with a plurality of slots 20.

[0058] This embodiment employs a structural design where a buckle 10 is provided on the locking member 121 and a slot 20 is provided on the connecting part 111. Furthermore, when the slot 20 is provided on the connecting part 111, a mating member 112 is also provided on the connecting part 111, with multiple slots 20 constructed on the mating member 112 of the connecting part 111. The buckle 10 on the locking member 121 locks the connecting part 111 by engaging with the slot 20 on the mating member 112. The mating member 112 can be integrally formed with the connecting part 111, protruding from the surface of the connecting part 111. Alternatively, the mating member 112 can be detachably connected to the connecting part 111, and the detachable connection method can include buckle 10 connection, screw connection, etc., depending on actual needs. The mating member 112 is detachable from the connecting part 111, facilitating maintenance / replacement.

[0059] In some embodiments, refer to Figures 4 to 7The locking member 121 has a receiving cavity 121Q, and the buckle 10 is located in the receiving cavity 121Q;

[0060] One end of the mating part 112 extends into the receiving cavity 121Q and can move within the receiving cavity 121Q when the connecting part 111 rotates.

[0061] The locking member 121 has a receiving cavity 121Q that is adapted to the mating member 112. Within the receiving cavity 121Q, a snap fastener 10 is located on the bottom wall of the cavity. Multiple slots 20 are located on the end face of one end of the mating member 112. One end of the mating member 112 extends into the receiving cavity 121Q from its opening and faces the bottom wall of the cavity, so that the multiple slots 20 and snap fasteners 10 are positioned opposite each other. When the armrest 110 is moved to adjust its angle / position, the connecting part 111 rotates to move the mating member 112 within the receiving cavity 121Q, thereby switching the alignment of different slots 20 on the mating member 112 with the snap fasteners 10. When the armrest 110 is adjusted to the desired angle / position, the snap fastener 10 engages with the corresponding slot 20, thereby locking the connecting part 111 to position the armrest 110. In this embodiment, the locking member 121 has a cavity 121Q for mounting the buckle 10 and accommodating the mating member 112. This design improves the compactness of the locking structure and conceals the mating structure of the buckle 10 and the slot 20. It is not easily affected or interfered with by the external environment and can ensure locking stability.

[0062] In some embodiments, refer to Figures 4 to 7 The mating part 112 is provided with a damping element 113, which contacts the cavity sidewall of the receiving cavity 121Q. The damping element 113 is used to generate a damping force by rubbing against the cavity sidewall of the receiving cavity 121Q when the connecting part 111 rotates; and / or,

[0063] The connecting part 111 is provided with a slot 111C, and the other end of the mating part 112 is inserted into the slot 111C.

[0064] In this embodiment, a receiving hole is provided through the mating member 112, and a damping member 113 passes through the receiving hole. Both ends of the damping member 113 protrude from the receiving hole and protrude from the opposite side walls of the mating member 112, respectively, and contact the cavity side wall of the receiving cavity 121Q. The damping member 113 can be made of silicone material, utilizing the good elasticity and frictional properties of silicone to generate damping force. When the armrest 110 is turned to adjust its angle / position, the mating member 112 moves accordingly in the receiving cavity 121Q as the connecting part 111 rotates. The damping member 113 on the mating member 112 rubs against the cavity side wall of the receiving cavity 121Q, thereby generating damping force. This damping force can slow down the rotation speed of the armrest 110, reduce noise, and provide the user with a "sturdy feel" during operation, improving the operating feel of adjusting the armrest 110. Damping grease can be applied to the damping component 113 to further increase the damping effect, slow down the rotation speed of the handrail 110 and reduce noise.

[0065] The slot 111C provided on the connecting part 111 is adapted to the mating part 112. The mating part 112 is inserted into the slot 111C through its other end to realize the insertion setting on the connecting part 111, which is stable and easy to install and remove.

[0066] In some embodiments, refer to Figure 6 Each slot 20 has a bottom wall and two oppositely arranged inclined side walls, with different inclination angles between the two inclined side walls and the bottom wall.

[0067] When the handrail 110 rotates outward, the buckle 10 moves along one of the two inclined sidewalls to disengage from the slot 20, and when the handrail 110 rotates inward, the buckle 10 moves along the other of the two inclined sidewalls to disengage from the slot 20.

[0068] When the handrail 110 is positioned at a certain angle / position, the latch 10 is engaged in a corresponding slot 20 to maintain the stability of the handrail 110. When the handrail 110 is pried open (outward or inward) to adjust its angle / position, the latch 10 moves along the inclined side wall of the slot 20 to disengage from the slot 20, and enters the next slot 20 as the handrail 110 rotates. Since the handrail 110 has two different directions of movement—outward and inward—the latch 10 disengages from the slot 20 in two different directions. When the handrail 110 is pried open and rotated outward, the latch 10 moves along one of the two inclined side walls of the slot 20 to disengage from the slot 20; conversely, when the handrail 110 is pried open and rotated inward, the latch 10 moves along the other inclined side wall of the slot 20 to disengage from the slot 20.

[0069] The angle of inclination of the inclined sidewall relative to the bottom wall of the groove affects the ease with which the buckle 10 can be disengaged from the groove 20. When the angle of inclination of the inclined sidewall is small, it is relatively easy for the buckle 10 to be disengaged from the groove 20; when the angle of inclination of the inclined sidewall is large, it is relatively difficult for the buckle 10 to be disengaged from the groove 20.

[0070] Therefore, by setting different inclination angles between the two inclined sidewalls and the bottom wall of the groove, the ease with which the user can pry the handrail 110 outward and inward can be differentiated. For example, when the handrail 110 rotates outward, the angle along one sidewall of the groove where the buckle 10 disengages from the buckle 20 is greater than the angle along the other sidewall of the groove where the buckle 10 disengages from the buckle 20 when the handrail 110 rotates outward, thus making it more difficult to pry the handrail 110 outward than to pry it inward.

[0071] In other words, by cleverly utilizing the difference in the tilt angle of the sloping side wall of the slot 20, the buckle 10 presents different levels of difficulty when it is pried out of the slot 20 from the inside and outside of the armrest 110, allowing users to adjust the armrest 110 more accurately and stably according to their own needs, avoiding unnecessary misoperation, and improving the overall comfort and safety of use.

[0072] In some embodiments, refer to Figure 5 and Figure 6 At least one of the connecting part 111 and the locking member 121 is connected to a spring 130, which is used to apply an elastic force to the connecting part 111 and / or the locking member 121 to which it is connected, so that the buckle 10 abuts against the slot 20 when it is engaged in the slot 20.

[0073] The connecting portion 111 may be connected to the spring 130, or the locking member 121 may be connected to the spring 130, or both the connecting portion 111 and the locking member 121 may be connected to the spring 130. When both the connecting portion 111 and the locking member 121 are connected to the spring 130, one end of the spring 130 may be connected to the connecting portion 111, and the other end of the spring 130 may be connected to the locking member 121. Furthermore, multiple springs 130 may be provided (e.g., two), and the multiple springs 130 may be distributed on opposite sides of the connecting portion 111.

[0074] The function of the spring 130 is to assist in locking. When the armrest 110 is moved to adjust its angle / position, the buckle 10 disengages from the slot 20 it holds, and the spring 130 is correspondingly stretched and in a taut state. When the user adjusts the angle / position of the armrest 110 and releases it, the elastic force of the spring 130 pulls the connecting part 111 and the locking member 121 together, and at the same time, the buckle 10 is engaged in the slot 20 and pressed against the slot 20. In this embodiment, by reasonably setting the spring 130 between the connecting part 111 and the locking member 121, the elastic force of the spring 130 ensures that the buckle 10 is firmly engaged in the slot 20, effectively resisting external interference and maintaining the stability of the armrest 110 at the set angle position.

[0075] During the rotation and adjustment process of the armrest 110, the spring 130 is prone to vibration and noise. Therefore, a silicone component can be configured for the spring 130 to dampen vibration and reduce noise. For example:

[0076] In some embodiments, a first silicone element is disposed within the spring 130; and / or,

[0077] The outer sleeve of spring 130 is equipped with a second silicone part.

[0078] The first silicone component can be a first silicone tube, the outer diameter of which is smaller than the inner diameter of the spring 130 and it passes through the spring 130. During the compression or stretching of the spring 130, the first silicone component can play an auxiliary buffering role, reducing the frictional noise of the spring 130.

[0079] The second silicone component can be a second silicone tube, the inner diameter of which is larger than the outer diameter of the spring 130 and is sleeved on the outside of the spring 130. During the compression or stretching of the spring 130, the second silicone component can play an auxiliary buffering role, reducing the frictional noise of the spring 130.

[0080] This utility model embodiment also proposes a seat, referring to... Figure 8 The seat includes a base 200, a seat cushion 300, a mounting frame 500, and an armrest assembly 100 as described in the foregoing embodiments. The seat cushion 300 is mounted on the base 200, and the mounting frame 500 is disposed on either the base 200 or the seat cushion 300. The specific structure of the armrest assembly 100 is as described in the foregoing embodiments. Since this seat adopts all the technical solutions of all the foregoing embodiments, it possesses at least all the technical effects brought about by the technical solutions of the foregoing embodiments, and will not be elaborated further here. The mounting frame 500 may be disposed on the base 200, serving as the structural frame of the base 200; or, the mounting frame 500 may be disposed on the seat cushion 300, serving as the skeleton of the seat cushion 300, and can be selected according to actual needs. Optionally, in this seat, there are two armrest assemblies 100, with the two armrest assemblies 100 respectively disposed on the left and right sides of the seat cushion 300.

[0081] In some embodiments, refer to Figure 2 and Figure 5 The mounting bracket 500 includes a first mounting rod 510 and a second mounting rod 520 arranged side by side at intervals;

[0082] The locking module 120 is slidably sleeved on the first mounting rod 510;

[0083] The connecting part 111 is slidably sleeved on the second mounting rod 520 and can rotate relative to the second mounting rod 520. The connecting part 111 can slide with the locking module 120 to adjust the position of the handrail 110.

[0084] The mounting bracket 500 has a dual mounting rod structure, with a first mounting rod 510 and a second mounting rod 520 arranged side-by-side at intervals, extending in the fore-and-aft direction of the seat. The connecting portion 111 of the locking module 120 and the armrest 110 is connected to the first mounting rod 510 and the second mounting rod 520 of the mounting bracket 500 respectively, thus being mounted on the mounting bracket 500. The locking module 120 is sleeved on the first mounting rod 510, forming a rotatable connection with the mounting bracket 500, and can slide along the first mounting rod 510; the connecting portion 111 is sleeved on the second mounting rod 520, achieving a rotatable connection with the mounting bracket 500, and can slide along the second mounting rod 520. That is, the locking module 120 and the armrest 110 are slidably mounted on the mounting bracket 500 and slide in the same direction.

[0085] When the handrail 110 is moved to adjust its angle / position, the connecting part 111 of the handrail 110 rotates around the second mounting rod 520 to change its relative position with the locking module 120. The locking module 120 locks the connecting part 111 to position the handrail 110.

[0086] The connecting part 111 is movably positioned to follow the locking module 120. When the locking module 120 slides on the first mounting rod 510, the connecting part 111 is correspondingly driven to slide on the second mounting rod 520 due to its locking engagement with the locking module 120. The locking module 120 can be linked to other components in the seat (such as the seat cushion). When other components in the seat move, they correspondingly drive the locking module 120, and the connecting part 111 slides with the locking module 120 to adjust the position of the armrest 110 in the fore-and-aft direction of the seat.

[0087] Alternatively, in other usage scenarios, the user can operate the armrest 110 to slide, so that the connecting part 111 slides on the second mounting rod 520. Due to the locking engagement with the connecting part 111, the locking module 120 is correspondingly driven to slide on the first mounting rod 510, thereby realizing the position adjustment of the armrest 110 in the front-back direction of the seat.

[0088] As an optional implementation, the mounting bracket 500 may further include support rods, which are arranged side-by-side with the first mounting rod 510 and the second mounting rod 520 at intervals. The outer wall of the connecting part 111 forms an arc-shaped abutment surface adapted to the support rod, and the support rod can abut against the arc-shaped abutment surface of the connecting part 111. When the connecting part 111 rotates, it rotates around the support rod accordingly, and the abutment position between the support rod and the arc-shaped abutment surface changes, but it always maintains support for the connecting part 111. That is, during the process of turning the handrail 110 to adjust its angle / position, the strong support of the connecting part 111 by the support rod can improve the stability of the rotation adjustment of the handrail 110.
