Description

One-touch coupling for furniture assembly {coupling for assembling furniture}

The present invention relates to a connector for furniture assembly, and more specifically, unlike the existing fastening method that was consistent with screws, bolts, nails, etc., protrusions of a set shape and corresponding grooves are formed on various elements to fit each other. A one-touch type connector for furniture assembly that maximizes convenience of use and efficiency due to the ease of handling, use, maintenance, and repair that comes from its differentiated structure from existing structures, such as the ability to quickly and easily assemble furniture as the combined structure is achieved. It's about.

Typically, furniture was sold in a finished form, but in recent years, the number of consumers looking for prefabricated furniture has been increasing due to high prices and bulky display, storage, and transportation.

Most of these prefabricated furniture can be assembled or disassembled using a hammer, driver, wrench, etc. However, for non-experts, it takes a long time to assemble and disassemble the furniture, and depending on the type of furniture, it is very difficult to assemble it alone, and there are various risks during the assembly or disassembly process. For this reason, there were problems such as damage to parts.

For example, as one of the technologies related to the furniture assembly method, Registered Patent Publication No. 10-0597475, "Furniture Assembly Fastening Device," is published, and the technology firmly joins the plates that make up the furniture without damaging them and re-assembles them after disassembly. It is a technology designed to maintain sturdiness even after assembly.

In detail, a fastening connector in which a horizontal plate with a vertical through hole formed in the center and a vertical plate with a horizontal through hole formed in the center are integrally formed on one upper side of the horizontal plate; and, penetrating the vertical through hole and the horizontal through hole. A fastening bolt; a fastening bolt that is fixed by being inserted into a bolt through hole and a receiving groove formed in a furniture plate, and has a female thread formed in the center of the body so that a fastening bolt passing through the vertical through hole and the horizontal through hole of the fastening connector can be screwed together. It consists of a nut sphere;

The above prior art prevents damage to the plates when assembling furniture, enables the assembly of standardized furniture in large quantities, is economical because the assembled furniture can be used without damage to the plates even when disassembled and reassembled, and reduces the contact area between the furniture's plates. As there is no damage, it contributes to maintaining the sturdiness of the furniture.

However, in the prior art, the fastening connector and the fastening nut must be installed in advance on the furniture plate, and a bolt hole for installing the fastening connector on the plate and a receiving groove for inserting the fastening nut into the plate must be separately formed. Due to the process and structure, the durability of the board rapidly deteriorates, which not only has a negative effect on the furniture, but also can be convenient to use after installation, but it cannot be considered an efficient technology because the installation process is very complicated and cumbersome.

Accordingly, other technologies have been developed to solve the existing inconvenience, and Registered Utility Model Publication No. 20-0469535, “Assembled Furniture that is Easy to Assemble and Disassemble,” is published. The technology includes: an upper plate having at least one first fastening groove formed on the lower side; and a support plate having a first connection formed on the upper side inserted into and fixed to the first fastening groove and having at least one second fastening groove formed on one side; and, both sides. It is a technology consisting of a lower plate in which the second connection formed in is inserted into the second fastening groove and fixed.

The above technology can be applied to all currently commercially available furniture, and in particular, it has been improved to enable easy assembly and disassembly, such that the top plate and support plate are fixed by inserting a connection into at least one fastening groove without using nails or screws. will be.

However, the prior art required high production costs because the protrusions and grooves had to be precisely engaged with each other, and when assembly and disassembly were repeated, another problem occurred, such as wear of the assembly part due to friction.

Therefore, it is possible to provide high-quality prefabricated furniture at a low cost by solving all the above-mentioned problems, and by actively improving the overall structure so that even non-experts can easily assemble and disassemble, a new concept of furniture assembly can meet the diverse needs of consumers. Technology for connectors is urgently needed.

In addition, the same reference numerals refer to the same elements throughout the specification.

The present invention relates to connectors for furniture assembly.

Above all, the present invention, unlike general fastening methods such as screws, bolts, and nails, provides a joining structure by mutual fitting by forming protrusions and corresponding grooves on the plywood or panels that make up furniture, making it possible to quickly and conveniently assemble furniture. It can be assembled, and the one-touch detachable structure allows repeated assembly and disassembly without damaging the furniture. Convenience of use is achieved due to the ease of handling, use, maintenance, and repair that comes from the differentiated structure from the existing structure. Please note that it is related to a one-touch type connector for furniture assembly that maximizes efficiency.

Figure 1 is a perspective view of a connector configured according to a preferred embodiment of the present invention, Figure 2 is an exploded perspective view of the connector proposed by the present invention, and Figure 3 is a usage state diagram showing the use form of the connector proposed by the present invention. 4 to 6 are diagrams illustrating step by step the use state of the connector proposed by the present invention.

The purpose of the connector of the present invention is to enhance the assemblability of prefabricated furniture as well as finished furniture by connecting the panels constituting the furniture more easily and conveniently. Accordingly, the present invention consists of panels for constructing furniture; and connectors for connecting each panel. The panel is composed of a plurality of panels depending on the type of furniture, but in the present invention, only the first panel (1) and the second panel (2) are mentioned for explanation.

The panel is composed of a first panel (1) having a screw hole (1a) on one side, and a second panel (2) having an insertion hole (2a) on one side. The second panel 2 may be arranged side by side from the first panel 1, at a right angle, or, in some cases, diagonally, depending on the type of furniture.

For example, the screw hole 1a of the first panel 1 means a hole with a set diameter and a thread formed along the inner diameter, and the insertion hole 2a of the second panel 2 means a hole made with a set diameter. It means hall.

The connector is composed of a connecting rod 10 installed on the first panel 1 and an insert 20 installed on the second panel 2.

The connecting rod 10 is coupled to the screw hole 1a of the first panel 1, and the remaining part except for the part coupled to the screw hole is exposed to the outside of the first panel, that is, to the front, and is connected to the second panel 2. It is inserted into the insert 20 installed in .

The insert 20 is inserted into the insertion hole 2a of the second panel 2, and allows the intervention of the connecting rod 10 coupled to the first panel 1, so that the first panel and the second panel are connected. It contributes the most to interconnection.

In particular, the insert 20 arbitrarily restrains the connecting rod through a linked action of expansion or contraction of the inner diameter when the connecting rod 10 intervenes, thereby inducing one-touch assembly of the first panel 1 and the second panel 2. It consists of

The connecting rod 10 includes a fastening portion 11 coupled to the screw hole 1a of the first panel 1; and a support portion 12 for mounting and supporting the connecting rod on the first panel; and a connection portion 13 substantially fitted into the insert 20.

The fastening portion 11 has a diameter set in accordance with the screw hole 1a, and has a length such that the coupling force with the screw hole is actively maintained even when external forces are applied in all directions when coupled to the screw hole, and the outer circumferential surface is Since threads corresponding to the screw holes are formed, it provides a firm connection with the first panel (1).

The support portion 12 is a portion extending from one end of the fastening portion 11 to a predetermined thickness, and has a diameter slightly expanded compared to the fastening portion. Therefore, when the fastening part 11 is installed in the screw hole 1a, the support part 12 is caught on the surface of the first panel 1 to prevent excessive insertion of the fastening part, resulting in screwing due to excessive insertion of the fastening part. Damage to the threads of the hole (1a) is actively prevented.

The support portion 12 may be assembled to be exposed to the surface of the first panel 1, or may be partially inserted into the screw hole 1a and not exposed to the surface of the first panel. For example, when assembled in a non-exposed form, the screw hole 1a must be machined in the form of a counterbore.

The connection portion 13 extends and protrudes from one end of the support portion 12 and is temporarily fitted into the insert 20. This connection portion 13 includes an extension portion 13-1 having a predetermined diameter larger than the inner diameter of the insert 20; and an entry portion 13-2 extending from the tip of the extension portion but gradually narrowing in diameter from the extension portion. ; and a restraining portion 13-3 that protrudes in a sphere shape from the tip of the entry portion and is caught at the setting portion of the insert.

Since the extension portion 13-1 has a slightly larger diameter than the inner diameter of the insert 20, the insert is expanded by a certain amount due to the diameter difference when inserted and entered into the insert. The insert 20 with an expanded outer diameter within the insertion hole 2a of the second panel 2 is strongly adhered to the inner diameter of the insertion hole and exerts a binding force.

The entry portion 13-2 allows the connecting rod 10 to easily enter the inside of the insert 20, and contributes to increasing the mutual coupling force by closely surrounding a section of the insert.

The restraining part 13-3 is substantially connected to the entering part 13-2 as it is caught and mounted on the end of the insert while entering the inside of the insert 20, and connects the connecting rod 10 and the insert 20. Contributes to the connection and combination of

The insert 20 includes a housing 21 inserted into the insertion hole 2a of the second panel 2; a pressing portion 22 surrounding and supporting a portion of the connecting rod 20; and, substantially A locking portion (23) that restrains the connecting rod; and a cut portion 24 that contributes to the expansion and contraction of the insert.

The housing 21 is formed in a cylindrical shape with an outer diameter and an inner diameter of a set diameter, and the length of the cylinder corresponds to the extension portion 13-1 of the connecting rod 10. The housing 21 can be easily inserted because its outer diameter is slightly smaller than the insertion hole 2a of the second panel 2. However, when the connecting rod 10 is inserted, the inner and outer diameters are expanded to a certain extent so that the housing 21 can be inserted. As it adheres to the hole, it exerts a certain binding force.

The housing 21 may be configured to include a spiral groove 21-1 in which a groove of a set depth is formed in a spiral shape along the outer peripheral surface. The spiral groove (21-1) is trapped between the insertion hole and the housing when the housing (21) is inserted into the insertion hole (2a) and provides a passage through which compressed air is discharged to the outside. In addition, the connecting rod (10) When inserted, the diameter expands and exerts frictional force when it comes into close contact with the insertion hole, thereby strengthening the close contact and contributing to increasing the bonding force.

The pressing portion 22 is a portion that extends and protrudes from the tip of the housing 21, and is formed in plural numbers along the cross section of the housing to surround the entry portion 13-2 of the connecting rod 10. The pressing portion 22 is bent at a set angle toward the inside of the housing 21 and is in stable close contact with the surface of the entry portion 13-2 whose diameter gradually narrows from the extension portion 13-1. and support is provided, and as a predetermined elastic force is exerted due to the bent structure, the closely adhered and supported entry portion is pressed to a certain extent, thereby contributing to increasing the bonding force between the connecting rod 10 and the insert 20.

The locking portion 23 is a portion bent outward from each end of the pressing portion 22 and serves to surround and temporarily restrain the restraining portion 13-3 of the connecting rod 10. Like the pressing part 22, the locking part 23 also exerts a certain elastic force due to its bent structure, so it adheres to and supports the restraining part 13-3 with a stronger force, and presses it to a certain extent to connect the connecting rod 10. ) and the insert (20), contributing to the increase in temporary restraint and bonding force.

The cut portion 24 refers to a portion cut from the catching portion 23 to the pressing portion 22. When the connecting rod 10 enters, the cut portion 24 forms a catching portion and a pressing portion according to the respective diameter differences between the restraining portion 13-1, the entering portion 13-2, and the extending portion 13-1 of the connecting rod. Expand or contract.

In other words, the cut portion 24 causes the pressing portion 22 and the locking portion 23 to expand by a predetermined amount. Accordingly, when the restraining portion 13-3 of the connecting rod 10 that enters through the housing 21 reaches the boundary between the pressing portion and the engaging portion, the diameter of the boundary is smaller than the diameter of the restraining portion, so the boundary is Force is applied, and the pressing part and the locking part expand by the difference in diameter of the restraining part. Afterwards, when the restraining part 13-3 leaves the boundary and arrives at the engaging part 23, the force applied to the boundary disappears and the expanded pressing part 22 and the engaging part shrink and return to their original positions, so that the pressing part becomes the entry part. (13-2) is surrounded and supported, and the hanging portion surrounds and supports the restraining portion.

Figure 7 is a cross-sectional view showing a form in which a connecting rod is forcibly restrained on an insert according to another embodiment of the present invention.

As described above, the present invention makes it easy to connect a plurality of panels by tightly contacting and restraining one or all parts of the connecting rod 10 through expansion and contraction of the pressing portion 22 and the locking portion 23 of the insert 20. Can be conveniently assembled and disassembled.

And, as shown in FIG. 7, at least one protrusion 13a is formed on the entry part 13-2 of the connecting rod 10, and an insertion hole (13a) is formed at each position corresponding to the protrusion on the pressing part 22 of the insert 20. 22a) may be further formed to forcibly fix and constrain the coupled state of the connecting rod and the insert by inducing mutual engagement between the protrusions and the fitting holes when the connecting rod and the insert are coupled.

The furniture assembly connector of the present invention, which has the above configuration, has a structure that can be fully assembled with bare hands without a separate assembly tool such as a hammer or driver, so it is extremely convenient not only for assembly but also for display, storage, transportation and management. In addition, unlike existing technologies in which external force is exceeded in the process of increasing the bonding strength of furniture by tightening bolts or screws, etc., causing collapse of screw threads or distortion of furniture, a strong bond is achieved simply by inserting the connecting rod into the insert. Therefore, it is possible to secure not only the stability of assembly and disassembly, but also the speed and simplicity of assembly and disassembly.

In addition, it has an extremely simple structure that can be applied to all currently commercially available furniture, so excellent efficiency can be expected. As a result, production costs can be reduced, and sales and purchases can be made at a low cost, thereby contributing to the economic growth of furniture-related companies. You can contribute. In addition, due to the one-touch connection structure, furniture can be easily assembled and separated, and the connection parts can be selectively forcibly restrained and fixed, allowing furniture to be installed for various purposes, and excellent practicality based on versatility can be expected.

As a result, the present invention maximizes convenience of use and efficiency due to ease of handling, use, maintenance, and repair resulting from its differentiated structure from the existing one.
