Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for connecting panels in a partition that partitions a work space such as an office, and more particularly to a structure that uses a plate-like member to connect the panels.

Patent Documents 1 to 3 are prior arts disclosing a structure (panel connection structure) in which a plate-shaped member is used to connect end faces of a plurality of panels to each other.

A plate-like L-shaped connecting member 50 is screwed. A plate-like L-shaped connecting fitting 4 is screwed. Japanese Patent No. 4157017 A pair of panels to be connected is attached to the lower end thereof with a leg member for supporting the panel, which is formed with a fitting groove whose lower end and outer end are open. , each end of the connecting member is fitted and fixed.

A panel connection structure that uses a plate-like member for connection has a simple structure, and the connection member can be manufactured at a low cost. In Patent Documents 1 to 3, plate-like members are connected by screwing or bolting. In Patent Document 3, the members are fitted together and then fixed with bolts. Moreover, the connection of the upper part of the panel is screwed.

Screwing and bolting are reliable fixing methods, but they are somewhat time-consuming. If the panels can be connected only by fitting while using plate-like members, the connection work will be simplified. However, there was no such panel connection structure.

The present invention has been made to solve the above-mentioned problems, and uses plate-shaped members that are simple in structure and can be manufactured at low cost. An object of the present invention is to provide a panel connecting structure.

The present invention relates to a panel connection structure in which end surfaces of a plurality of panels are butted against each other and connected,
A panel connection structure for connecting a plurality of panels by providing fitting grooves on the upper and lower sides of the end surface of the frame of the panel, and inserting a plate-like connection member from above and below,
The connecting member has a substantially "mountain" shape, and projections on both sides of the connecting member are openings provided in fitting grooves of the frame member in the lateral direction of the frame (hereinafter referred to as "horizontal fitting grooves"). , the base connecting the protrusions on both sides fits into the horizontal fitting groove, and the central protrusion of the connecting member fits into the fitting groove of the frame member in the vertical direction of the frame (hereinafter referred to as ("Longitudinal fitting groove") to connect the plurality of panels.

Two slits may be provided in the central projection, and the bottoms of the vertical fitting grooves of the frame may be fitted into the respective slits.

A notch for receiving a plug for preventing falling off is provided on the opposite side of the projection of the connecting member,
The lateral fitting groove of the frame is provided with a recess at a position corresponding to the notch,
A fall prevention portion provided on the plug may be configured to fit into the recess.

According to this invention, since the plurality of panels are connected by the connecting member, screwing is unnecessary, and the work for connecting can be easily performed.
By forming the connecting member into a substantially mountain shape, there is also an effect that the strength of the connecting member at the connecting portion is improved.
Furthermore, since the projection of the connecting member is provided with a slit into which the bottom of the vertical fitting groove is fitted, the connection can be reliably performed. Fitting with a slit suppresses rotation, making it difficult to come off.
Furthermore, the drop-off preventing plug can prevent the connecting member from dropping off. By inserting the drop-off prevention plug, there is an effect that the connection strength is further improved.
