Description

Technical Field

[0001] The utility model relates to the technical field of modular furniture, in particular to a USM modular furniture connector and USM modular furniture. Background Art

[0002] With the development of the furniture industry, ordinary standard furniture has become increasingly difficult to meet the needs of users, thus giving rise to the concept of "modular furniture". Modular furniture is a unique custom-made furniture that is designed with modularity and freely combined to meet the specific needs of customers. The size and function of modular furniture can be changed according to customer needs. It mainly meets user needs by using standard parts for personalized assembly. At the same time, new and old furniture can also be disassembled and reassembled to form new furniture. It is often used in various types of cabinet furniture.

[0003] In modular furniture, the Swedish modular furniture brand USM, as a representative of top quality and outstanding design in the furniture industry, has gradually become synonymous with modular furniture. USM applies the concept of architecture, takes spare parts as the core, uses connectors + steel pipes as the frame as the structural center of gravity, and adds steel plates, door panels and spare parts to form a complete cabinet. Among them, the chrome-plated ball as a connector has become a signature part of USM furniture, and the chrome-plated ball is a key part to realize various customized creations.

[0004] The chrome-plated ball is provided with a plurality of screw holes that are interconnected. After the screws are inserted into the screw holes, they are screwed into the expansion tubes. The steel tubes are sleeved on the expansion tubes and expanded by the expansion tubes to achieve the fixation of the steel tubes. However, due to the characteristics of modular furniture, modular furniture involves a lot of disassembly and assembly work. When the existing chrome-plated ball is connected to the steel tube, it is necessary to use a tool to insert the screws from the other side of the chrome-plated ball opposite to the connection position to expand the expansion tube. Especially when multiple directions of connection are involved, a screwdriver with the same length as the steel tube on one side or a special screwdriver needs to be customized to complete the fixation of the steel tube on the other side, which makes assembly very inconvenient.

[0047] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0048] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0049] Refer to the following Figures 1 to 5 To describe a USM modular furniture connector provided according to some embodiments of the present invention.

[0050] Some embodiments of the present application provide a USM modular furniture connector.

[0051] like Figures 1 to 5 As shown, the first embodiment of the utility model proposes a USM modular furniture connector, including: an adapter 1 and an expansion member 2.

[0052] The adapter 1 is provided with a plurality of assembly grooves 11, and the assembly grooves 11 are opened along the axial direction of the adapter 1; it is understandable that the number of assembly grooves 11 can be determined according to the position of the adapter 1 and the assembly angle of the connecting tube 3. For example, in a rectangular cabinet furniture, the number of connecting tubes 3 connected to the adapter 1 located at the edge is four, the number of connecting tubes 3 connected to the adapter 1 located at the vertex is three, the number of connecting tubes 3 connected to the adapter 1 located in the middle of the surface is five, and the number of connecting tubes 3 connected to the adapter 1 located inside the cabinet is six. The number of assembly grooves 11 on any adapter 1 is not less than the number of connecting tubes 3 connected to the adapter 1. In some embodiments, in order to improve the reusability of the adapter 1, the number of assembly grooves 11 on the adapter 1 can be uniformly set to six.

[0053] It should be noted that the axis of the adapter 1 in the present disclosure is a straight line passing through the center of the adapter 1, not a specific axis of symmetry. The adapter 1 can also be in various shapes, such as a sphere, a spherical body, a cube, a cube-like body, etc. The opening direction of the assembly groove 11 on the adapter 1 should match the setting angle of the connecting pipe 3. For example, in the cabinet structure, the connecting pipes 3 are arranged horizontally or vertically. At this time, the groove direction of the assembly groove 11 is also a matching horizontal direction and vertical direction.

[0054] The expansion member 2 includes a fixed section 21, an expansion section 22 and a first bolt 23. The fixed section 21 is detachably fixedly connected to the assembly groove 11, so that the assembly groove 11 forms a restriction on the rotation of the expansion member 2 along its circumferential direction; the expansion section 22 is arranged in a cylindrical shape, so that the expansion section 22 has the freedom to expand in a direction away from its axis. A first screw hole 221 is provided on one side of the expansion section 22, and the first bolt 23 is threadedly matched with the first screw hole 221 and has a first stroke and a second stroke; the first stroke is the side of the expansion section 22 where the first screw hole 221 is provided pointing to the other side opposite to the first stroke, and the second stroke is opposite to the direction of the first stroke.

[0055] Specifically, after the expansion member 2 is assembled on the assembly groove 11, the expansion member 2 should not be able to rotate, so that the first screw hole 221 is fixed to one side, that is, the insertion position and insertion direction of the first bolt 23 can be determined during assembly. In this embodiment, after the first bolt 23 is screwed into the first screw hole 221, it hits the inner wall surface of the expansion member 2, causing the expansion member 2 to expand outward, so that the outer wall surface of the expansion member 2 is in close contact with the connecting pipe 3. After loosening the first bolt 23, the expansion member 2 can be restored to its original shape, making it easy to separate the expansion member 2 from the connecting pipe 3. With this arrangement, the assembly of the connecting member and the connecting pipe 3 can be completed within the length range of the expansion member 2 without the need to use specific tools or specially made extended screwdrivers.

[0056] In some embodiments, the assembly groove 11 and the fixing section 21 can be assembled in a detachable manner by bolt connection, snap connection, etc. However, considering the applicability and economy, the assembly groove 11 and the fixing section 21 are connected by bolts.

[0057] Specifically, the assembly groove 11 is provided with a second screw hole 111, and the fixed section 21 is provided with a third screw hole 211; one end of the expansion section 22 is connected to the fixed section 21, and the other end is open; the second screw hole 111, the third screw hole 211 and the opening set at the end of the expansion section 22 form an assembly path, and the second bolt 4 is threadedly matched with the second screw hole 111 and the third screw hole 211 through the assembly path, so that the fixed section 21 is detachably fixedly connected to the assembly groove 11.

[0058] In some embodiments, the fixing section 21 at least partially matches the shape of the assembly slot 11, so that the fixing section 21 is plugged into the assembly slot 11. Figure 4 As shown, the shaking of the expansion member 2 can be reduced by inserting the fixing section 21 into the assembly groove 11. In a specific embodiment, the fixing section 21 and the assembly groove 11 can also be set as a mortise and tenon connection structure to increase the stability of the connection between the two.

[0059] In some embodiments, the shape of the assembly groove 11 can be set to limit the rotation of the expansion member 2. Specifically, the cross-section of the assembly groove 11 is a regular or irregular shape with a limiting function to limit the rotation of the expansion member 2 and limit the direction of the first screw hole 221. Among them, the regular shape can be a polygon, etc., and the irregular shape should have at least one edge to ensure that the limiting member does not rotate. Preferably, the cross-section of the assembly groove 11 can adopt the chamfered square shown in the figure, so that the direction of the first screw hole 221 is limited by the edge, which is convenient for later assembly and alignment.

[0060] In some embodiments, a first opening 24 is disposed on a wall surface of the expansion section 22 , and the first opening 24 is opened along the axial direction of the expansion section 22 , so that the expansion section 22 has the freedom to expand in a direction away from its axis.

[0061] In a specific embodiment, the first opening 24 includes a circular hole 241 and a strip hole 242; the strip hole 242 is arranged between the end of the expansion section 22 away from the fixed section 21 and the circular hole 241. The arrangement of the first opening 24 ensures that even if the expansion section 22 is made of a material with a certain rigidity, the expansion freedom can be retained.

[0062] In some embodiments, the surface of the expansion section 22 is provided with textures to increase the friction resistance of the contact position of the surface of the expansion section 22. As shown in the figure, stripes can be provided on the surface of the expansion section 22, and when the expansion section 22 abuts against the inner wall of the connecting pipe 3, the stripes can significantly increase the resistance.

[0063] The utility model proposes, including:

[0064] A plurality of connecting tubes 3, adjacent connecting tubes 3 are connected by a connecting piece as described in any one of the above technical solutions, wherein the connecting tube 3 is sleeved on the expansion piece 2; an assembly hole 31 matching the position of the first screw hole 221 is provided on the connecting tube 3, and the assembly hole 31 and the first screw hole 221 form an assembly path for the first bolt 23; a plurality of the connecting tubes 3 are connected by the connecting piece to form a main frame.

[0065] The second embodiment of the utility model provides a USM modular furniture, such as Figures 1 to 5 As shown, it includes several connecting pipes 3 and plates, and adjacent connecting pipes 3 are connected by connecting pieces as described in any one of the above technical solutions, wherein the connecting pipe 3 is sleeved on the expansion piece 2; the connecting pipe 3 is provided with an assembly hole 31 matching the position of the first screw hole 221, and the assembly hole 31 and the first screw hole 221 form an assembly path for the first bolt 23; a plurality of the connecting pipes 3 are connected by the connecting piece to form a main frame. The plate is assembled on the main frame to be used as a load-bearing plate, cabinet door, etc.

[0066] When in use, first put the connecting pipe 3 on the expansion piece 2, screw the first bolt 23 into the first screw hole 221 through the assembly hole 31, and continue to screw to expand the expansion piece 2, so that the connecting pipe 3 and the expansion piece 2 fit tightly and are locked.

[0067] In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0068] Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of this utility model should be included in the protection scope of this utility model.
