Description

A connecting device for the reinforcement frames of tabletop}

The present invention relates to a connector between the reinforcing frame to reinforce the strength of the upper plate, such as a desk, it is possible to adjust the angle of the reinforcing bar according to the shape of the upper plate can be easily adjusted according to the shape of the upper plate,

Compared with the existing structure, the structure is easy to manufacture and the product cost can be lowered, and the reinforcement frame can be simplified by providing the connection function of the reinforcement frame and the installation of the table leg at the same time. It relates to the connector of the reinforcement frame of the table top that can be fixed to the table.

In general, furniture such as a desk or a table in which a large area of the top plate is placed on a plurality of table legs is provided with a reinforcing frame on the back of the top plate to prevent the bending caused by the load applied to the top plate during use. Means for attaching and securing are often used.

These reinforcing frames are arranged along the top plate in a divided state and then installed on the top plate in the form of interconnection through welding or separate connectors.

Since the welding method is too cumbersome and the connection part becomes dirty, in recent years, the welding method is manufactured by using a separate connector.

The connector is installed at each point where the end of each reinforcement frame is located on the back of the upper plate is to form the end of each reinforcement frame to be coupled to each other reinforcing frame.

By the way, the existing connector has a fixed shape is always made only at a predetermined angle when connecting to the reinforcement frame, because in recent years the shape of the top plate is not a simple square, but a variety of shapes, so the frame along the various top plate In order to install the various connection angles of various types were required.

Therefore, in order to manufacture such various connectors, separate molds are required, so that not only is a cause of increase in manufacturing cost, but even if the connector is provided at various angles, any angle can be connected without limitation, so the shape of the top plate is ultimately designed. There is a problem that hinders the improvement of quality, such as being restricted by the.

Recently, in order to solve this problem, a connector for freely varying the connection angle with a reinforcing frame has been proposed. Such a prior art is the Republic of Korea Patent Publication No. 0207284 "variable table frame connector".

The prior art is the first of the first, second, third connecting member (2) (3) (4) rotated about the central axis (1) as shown in Figure 1 and 2, respectively, By connecting one end of each reinforcing frame (5) to the second connection member (2) (3) has the advantage of adjusting the arrangement angle of the reinforcing frame (5) to suit the shape of the top plate.

However, when looking at the overall structure, each connecting member (2) (3) (4) is implemented by assembling between each connecting portion (2a) (2b) (3a) (3b) (4a) (4b) separated up and down again If the total number of parts is too large, and additional parts such as screws for assembling between the connecting portions 2a, 2b, 3a, 3b, 4a, and 4b are considered, the structure becomes quite complicated. Therefore, not only the production is difficult, but also a lot of production costs have a problem.

In addition, the table legs 7 and the upper plate 8 and the fasteners 6 for coupling the connecting members 2, 3, and 4 must be provided separately, so that the overall structure and fabrication of the upper plate must be further complicated. .

In addition, the coupling between the first and second connection members 2 and 3 and the reinforcement frame 5 is also made simply by inserting the connection members 2 and 3 into the reinforcement frame 5 without any mutual fixing means. In this case, the reinforcement frame may be minutely shaken at the connection part, and thus the entire reinforcement frame connection structure is shaken.

Moreover, there is no fixing structure between each connecting member 2, 3, 4 and the top plate 8, so that the connecting member can be rotated finely, which can also cause overall shaking.

In addition to the problems with the reinforcing frame connector described above, the coupling between the table leg and the top plate is generally welded to the table leg fixture fixed to the top plate or to the fixture and the table leg as suggested by Korean Utility Model Application No. 1996-3817. It is formed by screwing together by forming female thread.

This screw fastening structure is simple compared to the existing fastening structure has the advantage that can be easily adjusted height.

However, these conventional table leg fasteners only serve as a connection medium between the table leg and the top plate, and do not have other functions, and thus, when the reinforcing frame is installed, a separate connector must be added.

That is, as described above, the method of manufacturing the existing table has a problem in that the overall structure and manufacturing are complicated because the fastener for coupling between the table leg and the upper plate and the connecting tool for coupling between the upper plate and the reinforcing frame must be separately provided.

The present invention is proposed to solve the problems of the prior art as described above,

First, it aims to facilitate the manufacture and installation of the connector by proposing a connector that can adjust the installation angle of the reinforcement frame with a simple structure compared to the existing one.

It also aims to simplify the overall configuration of the table by allowing not only the installation of reinforcing frames but also the installation of table legs with only connectors.

In addition, it aims to be able to firmly install the reinforcement frame and the connector on the top plate.

The present invention for achieving the above object,

Fixed body is formed on the back of the table top plate is formed in the insertion hole is coupled to the table legs,

Is coupled to the fixed body is rotated around the fixed body, the first side of the rotating body consisting of a first coupling wing is coupled to a separate top plate reinforcement on one side,

It is coupled to the fixed body is installed so as to rotate around the fixed body separately from the first rotating body, one side is characterized in that it comprises a second rotating body consisting of a second coupling wing coupled to the other reinforcement.

And the fixed body is a cylindrical shape that one end is fixed to the top plate,

The first rotating body has a form in which the first coupling blade protrudes and extends on one side of the first rotating ring into which the fixed body is inserted.

The second rotating body is characterized in that the second coupling blade protrudes and extends to one side of the second rotating ring into which the first rotating ring is inserted.

The present invention consisting of the above characteristic configuration,

First, since the table legs are installed in the form of direct insertion into the center of the connector, there is no need to provide a separate table legs fastener, there is an effect that can be easily manufactured and the cost can be reduced.

In addition, by directly fastening the table leg to the fixing body of the connector as described above, the number of connecting members can be reduced compared to the prior art that a separate third connecting member must be provided for the connection between the connecting leg and the table leg, thereby simplifying the connector structure. It can be effective.

And unlike the existing connector that implements one connection member by assembling each connection, the rotating body is manufactured in a single shape has the effect of further simplifying the connector configuration and manufacturing process.

In addition, since the table legs are directly fastened to the center of the connector, there is an advantage of increasing the load transfer effect to the stable coupling and reinforcement frame compared to the prior art in which the table legs and the connector are connected only through the third connection member.

Hereinafter, with reference to the configuration illustrated in the drawings will be described embodiments of the specific configuration and its operation of the present invention.

The connector 1000 of the present invention includes a fixed body 100 and a rotating body 200 as shown in [FIG. 3] to [FIG. 6].

First, the fixed body 100 is for the installation of the rotating body 200 and the table leg 300 to be described later, the cylindrical central shaft 110 and the upper end of the flange portion 120 is integrally provided with a shape Have

At this time, the insertion hole 112 is formed in the center of the central axis 110 along the axial direction, and the internal thread 114 is formed on the inner circumferential surface of the insertion hole 112 for coupling with the table leg 300 to be described later. The screw hole 122 is formed in the 120 and the flange portion 120 is installed in the form of being screwed to the back of the upper plate 400.

The rotating body 200 constituting the connector 1000 together with the fixing body 100 is to adjust the installation angle of the reinforcing frame 500 with the connection function of the reinforcing frame 500 substantially, again the first It is composed of a rotating body 210 and the second rotating body 220.

The first rotating body 210 is inserted into the central shaft 110, the first coupling ring for connecting the first rotating ring 212 and the reinforcement frame 500 is rotated about the central axis 110 ( 214 is formed integrally,

The first rotary ring 212 is a portion for coupling and rotation with the central axis 110 is a hollow cylindrical shape and the inner diameter is formed almost the same as the outer diameter of the central axis 110, but the central axis 110 is inserted In the first rotating ring 212 is formed to be smoothly rotatable.

In addition, a stepped portion 212a is formed on the upper outer circumferential surface of the first rotating ring 212, and an outer diameter of the upper part is larger than the outer diameter of the lower part based on the stepped part 212a.

The first coupling blade 214 protrudes outward from one side of the stepped portion 212a, and the first coupling blade 214 has a tubular shape as a whole, and one end and the top surface thereof are opened, so that the reinforcement frame 500 is provided. It is to be inserted into the first coupling blade 214 through the opening portion 214a and the upper surface is located on the same line as the upper surface of the flange portion 120 of the fixed body 100 as shown in FIG.

The reason why the top surface of the first coupling blade 214 is also dared to be opened as described above, if the upper surface is not opened and the reinforcing frame 500 is installed on the upper plate 400 by the thickness of the top surface of the first coupling blade. This is because the reinforcement frame is floating from the top plate.

In addition, an auxiliary piece 214b having a threaded hole 214c is provided at both sides of the upper end of the first coupling blade 214 so that the first coupling blade 214 is fixed to the upper plate 400, and screw holes 214d are formed on both side walls. ) Is formed to be fixed between the first coupling blade 214 and the reinforcing frame 500.

The bottom surface of the first fastening wing 214 is located below the step 212a when considering the general width of the upper and lower reinforcement frame as shown in FIG. Accordingly, a gap a is formed between the portion extending downward from the stepped portion 212a and the central axis 110, and the surface facing the first rotation ring 212 of the first fastening wings 214 is curved surface 214e. The second rotating ring 222 of the second rotating body 220 to be described below is inserted into the gap a to smoothly rotate.

Along with the first rotating body 210, the second rotating body 220 for connection with the other reinforcing frame 510 has a shape substantially the same as the first rotating body 210 as a whole.

In other words, the second rotation ring 222 coupled to the central axis 110 is rotated about the central axis 110 and the second coupling blade 224 for connecting the reinforcement frame 510 is integrally provided to be.

In this case, the inner diameter of the second rotary ring 222 is substantially the same as the outer diameter of the first rotary ring 212 so that the first rotary ring 212 is inserted into the second rotary ring 222.

Therefore, when assembling the connector 1000, the first rotary ring 212 and the second rotary ring 222 are coupled in an overlapping shape with respect to the central axis 110 as shown in FIG. 6, the second rotary ring 222. A part is inserted into the gap a between the first rotating ring 212 and the first coupling blade 214, and the top surface of the second rotating ring 222 is a stepped portion of the first rotating ring 212 ( 212a) is placed in a state that can no longer climb.

And one side of the second rotary ring 222 is provided with a second coupling blade 224 is connected to the reinforcement frame 510, the second coupling blade 224 has the same structure as the first coupling blade 214 The open portion 224a is formed at one end and the top surface, and the auxiliary piece 224b and the screw hole 224c are formed at both upper ends of the upper wall 400 to fix the upper portion 224a.

In addition, a screw hole 224d is formed on both side walls for coupling with the reinforcing frame 510.

At this time, as described above, as the top surface of the second rotating ring 222 caught on the stepped portion 212a is positioned below the top surface of the first rotating ring 212, the height of the top surface between the coupling blades 214 and 224. To fit the second coupling blade 224 is positioned higher than the top surface of the second rotary ring 222 by the height difference.

When comparing the present invention and the conventional connector in the structural aspect of the present invention, as described above, one coupling blade made of a tubular shape in one rotary ring is integrally formed and manufactured, whereas the prior art has a rotary ring and a coupling blade. Since one rotating body is implemented through mutual assembly in the vertically divided state, the present invention has a much simpler structure than the prior art. Therefore, as well as easy to manufacture and assemble the connector has the advantage of reducing the manufacturing cost.

Hereinafter will be described the operation of the present invention according to the above configuration.

First, when explaining the entire assembly process of the connector again as shown in [Fig. 3] the top plate 400, the fixing hole 100 is positioned at the point where the table leg is to be located, then the screw hole 122 of the flange portion 120 Fasten the fixing screw (B) to the upper plate 400).

Thereafter, the central shaft 110 passes through the first rotating ring 212 to install the first rotating body 210 and the second rotating body so that the first rotating ring 212 is inserted into the second rotating ring 222. By installing the 220, all installation of the connector 1000 is completed.

4 and 5, one end of the reinforcing frame 500 is inserted into the opening portion 214a of the first coupling blade 214, and then screw holes 214d on both side walls of the first coupling blade 214. By inserting the fixing screw (B) to the first coupling blade 212 and the reinforcement frame 500 by fastening to prevent shaking of the reinforcement frame 500 at the connection portion.

In this state, as shown in FIG. 7, the revolving frame 500 is disposed at an appropriate angle in accordance with the shape of the upper plate 400 by rotating the coupling blade 212 about the central axis 110.

Then, after placing the other connector at the point where the other end of the reinforcement frame 500 is located, as shown in [8a] and [FIG. 8b], connect the other end of the reinforcement frame 500 to the corresponding coupling wings, and repeat this process. As a result, the connection between the reinforcement frames is completed as shown in the drawing, and the reinforcement frames are arranged at various angles according to the shape of the upper plate 400.

In this state, the coupling blades 214 and 224 are fixed to the upper plate 400 by penetrating the fixing screws through the auxiliary pieces 214b and 224c of the respective coupling blades 214 and 224, and at the same time, each reinforcement frame 500 They are also in a state of being closely fixed to the top plate 400.

As described above, the present invention, unlike the prior art, as well as fixed between the coupling blades 214, 224 and the reinforcing frame 500 is also fixed between the coupling blades 214, 224 and the top plate 400 each reinforcement frame This shaking phenomenon can be prevented.

When the installation of the reinforcement frame is completed as shown in FIG. 9, the threaded portion 310 of each table leg 300 is inserted into the insertion hole 112 of the connector 1000 and the fixing body 100 by inserting the female thread of the insertion hole 112. 114 is installed in the form of screwing with each other.

Therefore, the structure of the connector itself becomes simple compared to the prior art, in which the connection member of the connector is additionally manufactured for unnecessary connection with the table leg 300.

In addition, since the connection of the reinforcement frame 500 as well as the installation of the table leg 300 with only the connector 1000 can be installed, the overall structure and materials of the table compared to the existing technology that must be provided separately from the connector of the reinforcement frame and the table leg Savings can be achieved.
