Description

Table leg connection structure Technical Field

[0001] This invention relates to a table leg connection structure, specifically a structure that uses a box to accommodate table legs, with connecting rods that can be inserted into the box and fitted with snap-fit ​​elements inside the box. This allows the connecting rods to be initially positioned, facilitating the assembly and configuration of the table body. Prior Technology

[0002] Note that tables are an indispensable piece of furniture in modern home life, office spaces and teaching environments. Depending on different usage needs (such as conference tables, office desks, dining tables, etc.), there are different designs in terms of tabletop size and table leg structure. With the increasing demand for logistics transportation and flexible space utilization, most existing tables adopt a detachable and modular structural design to facilitate flat packaging at the production end and assembly by users or assembly personnel on site.

[0003] However, existing detachable tabletops still have several shortcomings in the assembly of table legs and horizontal support rods. Traditional assembly methods mostly rely on fasteners such as screws and bolts for positioning and locking. During assembly, personnel must simultaneously support the heavy table legs and long-span connecting rods, and accurately align the holes before locking. This makes the assembly process cumbersome and difficult, and single-person operation is prone to rod detachment or scratching of components. In addition, if only a single bolt point is used for connection, the structural stability is often insufficient, and long-term use can easily lead to shaking or metal fatigue. Moreover, existing connection structures are mostly exposed, which not only affects the aesthetics but is also easily damaged by collisions. Therefore, how to develop a table leg connection structure that is simple in structure, has a preliminary positioning function, and can improve assembly convenience and stability is a problem that relevant manufacturers urgently need to solve.

[0004] In view of this, the creator has specifically researched and improved the ease of assembly of the table body and legs, hoping to improve the above-mentioned problems with a better creation. After a long period of research and development and continuous testing, this creation was finally born. Summary of the Invention

[0005] Therefore, this invention is designed to solve the aforementioned problems and achieve the above objectives. We, the creators, provide a table leg connection structure, which includes: a box body with an upper opening at the top and a side opening on one side; the upper opening and the side opening are connected, and at least one snap-fit ​​element is provided on the inner wall of the box body; the side opening is used to cover and connect a connecting rod, and the connecting rod is provided with a connection part corresponding to the snap-fit ​​element, so that when the connecting rod is inserted into the box body, the connection part is correspondingly connected to the snap-fit ​​element.

[0006] According to the table leg connection structure described above, at least one set of connecting pieces is arranged laterally at the opening of the box body, and the connecting pieces are provided with at least one assembly part.

[0007] According to the table leg connection structure described above, the box body has an opening at its top, and the assembly part is located inside the opening at the top of the box body.

[0008] The table leg connection structure described above further includes a fixing plate, which forms a connecting surface at one end face, and the fixing plate is further provided with an assembly unit corresponding to the assembly part.

[0009] According to the table leg connection structure described above, the fixing plate is further provided with a fixing piece at one end face opposite to the connecting surface, and a receiving piece is provided on one side of the fixing piece; a notch corresponding to the box body is formed between the fixing piece and the receiving piece, so that the box body is located in the notch and fixed between the fixing piece and the receiving piece.

[0010] The table leg connection structure described above further includes a table leg with a crossbar and two uprights. The uprights are vertically installed at the bottom end of the crossbar, and the box system is correspondingly positioned at one end of the crossbar relative to the uprights.

[0011] According to the table leg connection structure described above, it further includes a fixing element, which is L-shaped, so as to form a first set of connectors at one side end and a second set of connectors at one bottom end. The first set of connectors and the second set of connectors are arranged perpendicular to each other, and the first set of connectors is positioned at the crossbar of the table leg, while the second set of connectors is positioned at the connecting rod.

[0012] According to the table leg connection structure described above, the snap-fit ​​element is a protrusion, and the assembly part is a groove corresponding to the snap-fit ​​element.

[0013] According to the table leg connection structure described above, the snap-fit ​​elements are arranged in a plurality of arrays.

[0014] Based on the above explanation and settings, it is evident that this creation possesses the following main advantages and effects, which are detailed below:

[0015] 1. This invention utilizes a box-like design, with interlocking elements on the inner wall and connecting rods working together to achieve immediate and precise initial positioning of the connecting rods as they are inserted into the box. This structural design not only significantly simplifies the tedious process of manually aligning holes during the assembly of traditional table legs and crossbars, improving the convenience and efficiency of single-person assembly, but also, through the multiple arrays of interlocking elements, more stably restricts the displacement of the connecting rods, effectively enhancing the stability of the table during assembly and preventing damage to components or assembly errors caused by rod slippage.

[0016] 2. This invention uses the notch design of the fixing plate to firmly clamp the box body, and further uses L-shaped fixing elements to vertically lock the table leg crossbar and connecting rod, which can significantly enhance the overall structural strength and anti-vibration capability of the table. This modular connection method not only makes the disassembly and assembly of the table frame more convenient, but also encloses the main connecting structure in the box body, which can also improve the integration and aesthetics of the furniture appearance. At the same time, it can maximize the convenience of table assembly and production efficiency while ensuring structural stability. Simple Explanation of the Diagram

[0018] This invention relates to a table leg connection structure. Its implementation methods, characteristics, and effects are described in detail below with several preferred and feasible embodiments and accompanying drawings, so that you may gain a deeper understanding and appreciation of this invention.

[0019] First, please refer to Figures 1 through 3. This creation is a table leg connection structure, which includes:

[0020] A box body 1 has an upper opening 11 at the top and a side opening 12 on one side; the upper opening 11 and the side opening 12 are connected, and at least one snap-fit ​​element 13 is provided on the inner wall of the box body 1; the side opening 12 is used to cover and connect a connecting rod 2, and the connecting rod 2 is provided with a connection part 21 corresponding to the snap-fit ​​element 13, so that when the connecting rod 2 is inserted into the box body 1, the connection part 21 is correspondingly connected to the snap-fit ​​element 13, so that the connecting rod 2 can be initially connected to the box body 1.

[0021] Regarding the configuration of the assembly part 21 and the snap-fit ​​element 13, in one embodiment, the snap-fit ​​element 13 is a protrusion, and the assembly part 21 is a groove corresponding to the snap-fit ​​element 13, so that the relative displacement of the connecting rod 2 in the housing 1 can be restricted through the interlocking of the protrusion and the groove; in order to further improve the stability of positioning and the torque resistance, the snap-fit ​​element 13 is preferably arranged in a plurality of arrays on the inner wall of the housing 1, thereby increasing the force-bearing area, so that the connecting rod 2 is not easy to shake after being inserted into the housing 1, and ensuring the accuracy of subsequent locking operations.

[0022] In one embodiment, the snap-fit ​​element 13 can be formed by opening a groove at the bottom of the box body 1, so that the snap-fit ​​element 13 can be formed by stamping, bending or other methods, so that the snap-fit ​​element 13 can be set in a geometrically shaped sheet, and the assembly part 21 can be in the form of a groove corresponding to its contour, so as to directly snap or fasten.

[0023] Therefore, the box 1 is used to be arranged on a table leg 4. As shown in Figures 2 and 3, in one embodiment, the table leg 4 has a crossbar 41 and two uprights 42. The uprights 42 are vertically arranged at the bottom end of the crossbar 41, and the aforementioned box 1 is correspondingly positioned at the other end of the crossbar 41 relative to the uprights 42. The table leg 4 and the connecting rod 2 can be horizontally assembled and arranged through the box 1, and then connected to the box 1 arranged on the other table leg 4, so as to easily complete the frame of a table between the two table legs 4. Each table leg 4 can be equipped with one or more box 1s to accommodate one or more connecting rods 2s.

[0024] When the box body 1 is configured, in order to cover the opening 11 on the upper part of the box body 1 so that the connecting rod 2 can be fixedly connected and the assembly part 21 can be reliably configured in the snap-fit ​​element 13, at least one set of connecting pieces 14 can be provided laterally at the opening 11 on the upper part of the box body 1, and the top end of the connecting rod 2 corresponds to the top end of the assembly piece 14. The assembly piece 14 is provided with at least one assembly part 15, which can be connected to other parts (such as: plate) through the assembly part 15, so that the upper opening 11 can be closed, and the box body 1 and the connecting rod 2 can be connected to each other without detaching from each other; in one embodiment, the assembly part 15 is provided on the inside of the upper opening 11 of the box body 1, so that the overall structure of the box body 1 is more concise and its overall volume can be reduced.

[0025] As shown in Figures 4 and 5, for fixing the box body 1 and closing the upper opening 11, it is preferable to use a fixing plate 3. The fixing plate 3 has a connecting surface 32 formed at one end face, and the fixing plate 3 is provided with a connecting unit 31 corresponding to the aforementioned box body assembly part 15. By interlocking or locking the connecting unit 31 with the assembly part 15, the fixing plate 3 can cover the upper opening 11 of the box body 1 to achieve structural closure. Furthermore, at the other end face of the fixing plate 3 opposite to the connecting surface 32, a fixing piece 33 and a receiving piece 34 are further provided. Between the fixing piece 33 and the receiving piece 34, a notch 35 corresponding to the box body 1 is formed, so that the box body 1 is located in the notch 35 and fixed between the fixing piece 33 and the receiving piece 34, so that the box body 1 can be fixed in the side direction, and the overall fixing strength can be improved. It can also distribute the force to the fixing plate 3, and avoid deformation of the connection due to long-term load.

[0026] To further enhance the stability of the connection between the table leg 4 and the connecting rod 2, as shown in Figures 6 and 7, a fixing element 5 can be configured. This fixing element 5 is L-shaped, forming a first set of connectors 51 at one end and a second set of connectors 52 at the bottom. The first set of connectors 51 and the second set of connectors 52 are arranged perpendicular to each other. The first set of connectors 51 is positioned at the crossbar 41 of the table leg 4, and the second set of connectors 52 is positioned at the connecting rod 2. In one embodiment, the first set of connectors 51 and the second set of connectors 52 can be configured as a through groove to facilitate screws for locking to the table leg 4 and the connecting rod 2 respectively. Through this L-shaped fixing element 5, secondary locking in the vertical dimension can ensure that the table leg 4 and the connecting rod 2 will not detach due to external force collision.

[0027] Thus, as shown in Figure 8, this invention utilizes the interlocking element 13 on the inner wall of the box 1 and the connection part 21 of the connecting rod 2 to achieve immediate positioning of the components during the initial assembly stage. Combined with the clamping design of the notch 35 of the fixing plate 3 and the reinforcement of the L-shaped fixing element 5, once the box 1, table legs 4, fixing plate 3, and connecting rod 2 are fixed together, the frame of the table is formed. Subsequently, the tabletop can be directly fixed to the top of the frame to complete the overall assembly of the table. This configuration not only effectively improves the convenience and production efficiency of table assembly, but also allows for modular configuration of each component, reducing the overall volume when not assembled, thereby improving the convenience of transportation. Furthermore, its overall configuration can achieve excellent structural stability and earthquake resistance while maintaining aesthetic appeal.
