Description

Connector and skeletal structure using the same {CONNECTOR, AND FRAME STRUCTURE USING THE CONNECTOR}

The present invention relates to a connector having a simple structure, easy to assemble and disassemble, and a skeletal structure using the connector.

Skeletal structures such as various shelves, display stands, storage cabinets, etc., have a structure in which rod-shaped elements constituting the skeleton are coupled to the connector in various directions (see Patent Documents 1 to 8).

Such a skeletal structure is simple in structure, easy to assemble and disassemble, and has been developed in order to secure excellent structural rigidity.

In general, a conventional skeletal structure includes a connector having a complicated structure, and is formed by inserting two or more rod-shaped end portions to the connector and fastening them with a separate screw or bolt, or the end portions of the rod-shaped elements in various directions. It was made by screwing directly into the connector.

For example, in the skeletal structures disclosed in Patent Literatures 1 to 5, the end portions of two or more rod-shaped elements are sandwiched in a connector and fixed with a separate screw or bolt.

This skeletal structure consists of a complex fastening structure in which the end of the rod-shaped element and the connector are complex, or a separate screw or bolt must be fastened to fix the rod-shaped element and the connector.

In addition, such a skeletal structure is impossible or difficult to construct a multi-layered or double-rowed skeletal structure due to the structure of the connector.

For example, in the skeletal structures disclosed in Patent Literatures 6 to 7, the screw holes are made to the ball-shaped connector in various directions, and the rod-shaped element is directly screwed to the screw holes.

However, such a skeletal structure is cumbersome in that the size of the connector must be excessively large in order to secure a depth for screwing the rod-shaped element into the connector, while the rod-shaped element must be screwed into the connector one by one.

In addition, in order to connect a plurality of rod-shaped elements, each of which has one end screwed to a plurality of neighboring connectors, to another connector in a different direction, respectively, when the rod-shaped element is turned in the screw direction, The screw direction is reversed and released from the connector. Because of this, it is difficult or impossible to form an intact skeletal structure.

For example, Patent Document 8 discloses a form having a rod-like element having a form in which bolts are slidably mounted at both ends of a tube, and connectors having screw holes formed in various directions.

According to this configuration, the bolts are rotatably mounted at both ends of the rod-like element, and the bolts can be fastened by rotating the bolts in opposite directions with respect to the two connectors, so that the problems in the aforementioned Patent Documents 6 to 7 do not occur. .

However, in order to rotatably mount bolts at both ends of the tube, which are rod-shaped elements, there are disadvantages in that complex components such as connecting caps, bolts, and clamps must be provided on both sides of the tube, respectively.

In particular, since the bolt is rotatably coupled to the pipe, the rod-shaped element itself and the structure are inevitably shaken due to the radial and axial clearance generated at the rotational part, and thus the structural rigidity of the entire skeleton structure. Is lowered.
