Description

Technical Field

[0001] This utility model relates to the field of office furniture technology, and in particular to a chair structure with a row connection function. Background Technology

[0002] In various group activities such as meetings and training sessions, to ensure stability and order when multiple people are seated and to prevent chairs from tipping over or shifting due to collisions or movement, it is often necessary to connect multiple chairs side by side into a single unit. Based on this need, existing technologies have developed various meeting chairs and training chairs with interlocking functions. These chairs typically have corresponding interlocking structures on the sides or bottom of the seat, such as the interlocking structure of buckles and slots, or the interlocking structure of hooks and rings. By interlocking the structures on adjacent chairs, multiple chairs can be connected sequentially, effectively improving the overall integrity and stability of the chair arrangement.

[0003] However, existing chairs with snap-fit ​​structures have significant shortcomings in practical use. Specifically, the snap-fit ​​structures on current chairs are mostly fixed, meaning they lack telescopic functionality. When the chair is not needed, the outward-extending snap-fit ​​structure cannot be retracted to the bottom of the seat or other concealed locations, remaining exposed on the outside of the seat or bottom. This problem directly leads to two adverse effects: Firstly, the exposed snap-fit ​​structure is prone to collisions with people and other objects during movement, carrying, or daily use, potentially causing injury and damage to the structure itself, affecting its subsequent connection function. Secondly, the outward-extending snap-fit ​​structure detracts from the overall aesthetics of the chair, making it appear awkward and irregular when not connected, which is incompatible with the aesthetic requirements of modern office and training spaces. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a chair structure with a row-connecting function.

[0005] A chair structure with a row-connecting function designed for this purpose includes a chair frame, a chair seat, a first movable member, and a second movable member; the first movable member is disposed below the chair seat and is movable left and right relative to the chair frame, and a connecting slot is provided on the left side of the first movable member; when the first movable member moves relative to the chair seat, it can drive the connecting slot to move outward or be stored under the chair seat; the second movable member is disposed below the chair seat and is movable left and right relative to the chair frame; a connecting fastener is provided on the right side of the second movable member; when the second movable member moves relative to the chair seat, it can drive the connecting fastener to move outward or be stored under the chair seat.

[0006] Preferably, the chair frame is provided with a first fixing rod and a second fixing rod, which are spaced apart from each other on the left and right sides;

[0007] The first fixed rod is provided with a first guide hole that runs through the left and right sides. The first movable part is movably inserted into the first guide hole. A limit element is provided at the end of the first movable part away from the connecting groove. The first fixed rod is disposed between the connecting groove and the limit element.

[0008] The second fixing rod is provided with a second guide hole that runs through the left and right sides. The second moving part is movably inserted into the second guide hole. A limit element is provided at the end of the second moving part away from the connecting fastener. The second fixing rod is located between the connecting fastener and the limit element.

[0009] Preferably, a decorative shell is also included, which is disposed below the seat.

[0010] The first fixing rod and the second fixing rod are disposed inside the decorative shell;

[0011] The decorative shell has through slots on both the left and right sides, and the first and second movable parts are movably inserted into the through slots.

[0012] Preferably, the chair frame includes support frames spaced apart front and rear, with the first fixing rod and the second fixing rod disposed between the two support frames.

[0013] The front and rear support frames are fixedly connected to the first fixed rod and the second fixed rod.

[0014] Preferably, the chair also includes a backrest, which is fixedly connected to the chair frame or seat.

[0015] This chair structure with a row-connecting function brings many significant benefits by incorporating a first and a second movable component that can move left and right relative to the chair frame:

[0016] Firstly, it achieves flexible storage and use of the interlocking structure. When multiple chairs need to be connected in a row, the first and second moving parts can be moved to move the connecting slot on the left side of the first moving part and the connecting fastener on the right side of the second moving part to the outside of the chair seat. At this time, the connecting slots and fasteners of adjacent chairs can quickly and accurately engage, ensuring the stability of the row connection and meeting the needs of the overall arrangement of chairs in scenarios such as meetings and training. When there is no need to connect, the first and second moving parts can move the connecting slots and fasteners to be stored under the chair seat, avoiding the problem of the interlocking structure being exposed for a long time.

[0017] Secondly, it effectively solves the drawback of existing fastening structures being prone to impacts. Since the connecting slots and fasteners can be stored under the seat when not in use, the probability of them colliding with people or other objects is reduced. This not only lowers the risk of injury to people but also protects the fastening structure itself, extends its service life, and ensures the reliability of subsequent connection functions.

[0018] Furthermore, it enhances the overall aesthetics of the chair. When folded, the connecting slots and fasteners are hidden under the seat, preserving the chair's neat appearance. This allows the chair to maintain a simple and harmonious visual effect whether used alone or not, better meeting the aesthetic demands of modern offices and training spaces.

[0019] Furthermore, the structure is ingeniously designed and easy to operate. The extension and retraction of the interlocking structure are achieved by moving the first and second moving parts left and right. The action is simple and intuitive, requiring no complicated operation steps, allowing users to quickly switch the chair's state according to actual needs, thus enhancing the chair's practicality and ease of use.

[0033] See Figures 1-5A chair structure with a row-connecting function includes a chair frame 10, a seat 20, a first movable member 40, and a second movable member 50. The first movable member 40 is disposed below the seat 20 and is movable left and right relative to the chair frame 10. A connecting slot 410 is provided on the left side of the first movable member 40. When the first movable member 40 moves relative to the seat 20, it can drive the connecting slot 410 to move outward or be stored under the seat 20. The second movable member 50 is disposed below the seat 20 and is movable left and right relative to the chair frame 10. A connecting fastener 510 is provided on the right side of the second movable member 50. When the second movable member 50 moves relative to the seat 20, it can drive the connecting fastener 510 to move outward or be stored under the seat 20.

[0034] The working principle of this chair structure with a row connection function is based on the movable characteristics of the first movable component 40 and the second movable component 50, so as to realize the flexible cooperation and storage of the connecting slot 410 and the connecting fastener 510, as follows:

[0035] When multiple chairs need to be connected in a row, for a single chair, the first moving part 40 can be moved to the left relative to the chair frame 10, causing the connecting fastener 410 on its left side to move from under the seat 20 to the outside; simultaneously, the second moving part 50 can be moved to the right relative to the chair frame 10, causing the connecting fastener 510 on its right side to move from under the seat 20 to the outside. Then, by arranging adjacent chairs so that the connecting fastener 410 of one chair engages with the connecting fastener 510 of another chair, the connection between the two chairs can be completed. By operating in the same manner, multiple chairs can be connected in an orderly manner.

[0036] When the chair is used alone without the need for a connecting frame, the first moving part 40 is moved to the right relative to the chair frame 10, and the connecting buckle slot 410 moves with it and is stored under the seat 20; the second moving part 50 is moved to the left relative to the chair frame 10, and the connecting buckle 510 moves with it and is stored under the seat 20. At this time, the chair returns to its independent state and does not affect its use alone.

[0037] See Figure 2 , Figure 3 and Figure 5The chair frame 10 is provided with a first fixing rod 120 and a second fixing rod 130, which are spaced apart from each other. The first fixing rod 120 is provided with a first guide hole 121 that extends from left to right. The first moving member 40 is movably inserted into the first guide hole 121. A limiting element 70 is provided at the end of the first moving member 40 away from the connecting groove 410. The first fixing rod 120 is located between the connecting groove 410 and the limiting element 70. The first guide hole of the first fixing rod provides guidance for the left and right movement of the first moving member. The limiting element cooperates with the first fixing rod to prevent the first moving member from coming out of the first guide hole.

[0038] The second fixing rod 130 is provided with a second guide hole 131 that extends from left to right. The second moving member 50 is movably inserted into the second guide hole 131. A limit element 70 is provided at the end of the second moving member 50 away from the connecting fastener 510. The second fixing rod 130 is located between the connecting fastener 510 and the limit element 70. The second guide hole of the second fixing rod provides guidance for the second moving member to move left and right. The limit element cooperates with the second fixing rod to prevent the second moving member from coming out of the second guide hole.

[0039] The limiting element 70 uses an existing pin, such as a cotter pin. Pin holes are provided in the first moving member 40 and the second moving member 50, and the pin is inserted into these holes. By inserting into the pin holes of the first and second moving members, it can effectively cooperate with the first and second fixed rods, precisely limiting the movement range of the first and second moving members, reliably preventing them from disengaging from the first and second guide holes respectively, and further ensuring the stability of their movement process.

[0040] See Figure 2 , Figure 3 and Figure 5 The system also includes a decorative shell 60, which is disposed below the seat 20. The first fixing rod 120 and the second fixing rod 130 are disposed within the decorative shell 60. The left and right walls of the decorative shell 60 are each provided with a through groove 610, into which the first movable member 40 and the second movable member 50 are movably inserted. The decorative shell, disposed below the seat, conceals components such as the first and second fixing rods, providing protection and enhancing the structural aesthetics. The through grooves on its left and right walls provide a passage for the first and second movable members, ensuring smooth left and right movement to facilitate the extension and retraction of the fastening structure.

[0041] See Figure 2 , Figure 3 and Figure 5The chair frame 10 includes support frames 110 spaced apart front to back, with the first fixing rod 120 and the second fixing rod 130 positioned between the two support frames 110. The two support frames 110 are fixedly connected to the first fixing rod 120 and the second fixing rod 130. The spaced-apart support frames in the chair frame are fixedly connected to the first and second fixing rods. On one hand, this forms a stable frame structure, providing a reliable installation foundation and support for the chair seat and the first and second moving parts, enhancing the overall structural strength and stability of the chair. On the other hand, this connection method can guide and limit the movement of the first and second moving parts, ensuring the smoothness and accuracy of their left and right movements.

[0042] This utility model also includes a chair back 30, which is fixedly connected to the chair frame 10 or the chair seat 20.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
