Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a connector for butting and connecting edge frame materials that hold panels on which photographs, posters, etc. are attached to a flat mount. In particular, it has both the function of locking the hanging string and the function of easily removing the connection of the edge frame materials once connected.

[Conventional technology]

Conventionally, in such a panel, the edge frame members 1, 1 are arranged perpendicularly on the outside of the front L-shaped receiving bracket on the inside of the cross-sectional edge frame member, as shown in FIG. Screws 20, 20 are screwed into the screw holes 18, 19 drilled in each edge frame material 1, 1 from the outside of the edge frame materials 1, 1, and the screws 20, 20 are tightened and connected.
Further, at the top of the panel, when tightening the screws 20, the mounting bracket 21 of the hanging cord 16 was attached at the same time. However, in such a structure, in order to connect the four edge frame members 1 into a rectangular frame shape, it is necessary to tighten at least eight screws 20, which is extremely time-consuming. 21 may become loose or damaged, making the panel unstable.

In order to solve this problem of tightening with a large number of screws, the applicant filed Utility Model Application No. 59-107711 for a device relating to a connection structure in which each edge frame member is connected using a connecting tool as shown in Fig. 2. The structure of this invention still has the problem that a mounting bracket for locking a hanging string for hanging the panel must be separately attached to the edge frame material.

[Means for solving problems]

Of the connectors formed by connecting two fitting arm pieces at right angles, each of the two connectors has a protrusion extending from the upper surface of one of the fitting arm pieces, and the protrusion is passed through the protrusion. A hole is provided, and a hanging string is inserted through the hole and locked.

[Effect]

Attach each fitting arm of each connector to the fitting part of the edge frame material, and place the connector with a protrusion on the upper surface of one of the fitting arms so that the protrusion is at the top. If used at both ends, the protrusions provided on the bottom of each fitting arm piece will be locked into the engagement holes provided on the bottom wall of the fitting part, and each edge frame material will be connected and fixed at the same time at the top of the panel. A hanging string is passed through a hole in a protrusion provided on the fitting arm piece and is locked therein. In addition, when disconnecting the edge frame materials that have been connected, insert the tip of a pin or the like into the protrusion hole of the edge frame material and press down the other end of the pin using the shoulder of the edge frame material as a fulcrum. The protrusion provided on the bottom surface of the joint arm piece is disengaged from the bottom wall engagement hole of the fitting portion, and the edge frame material can be easily removed.
