Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an assembly fitting that allows picture frames to be assembled and dismantled easily and quickly.

[Conventional technology]

Conventionally, frameworks that can be formed using materials such as aluminum and synthetic resins that can be relatively easily manufactured into the desired cross-sectional shape by extrusion molding are made by cutting a long extrusion molded product into specified dimensions and at an angle, and then pushing the cut surfaces against each other. They are then joined together using screws, etc., to form picture frames and other frameworks. This screw fastening method requires a lot of effort to assemble and also requires a lot of effort to dismantle. In order to improve this, the applicant of the present application proposed a device disclosed in Japanese Utility Model Application Publication No. 54-54143.

[The problem that the idea attempts to solve]

Although the device disclosed in Japanese Utility Model Application Publication No. 54-54143 can be easily and securely assembled into a picture frame, it cannot be disassembled quickly. That is, in this known method, a hook-shaped engagement piece is provided on a dog-shaped coupling fixing plate to be fixed in a frame material, and a coupling piece having a tapered end is tightened with a screw to attach the engagement piece to the coupling piece. Since it fits into the elongated hole, no effort is required for assembly. However, even when the screws are tightened during disassembly, the hook-like engagement piece does not easily come off the long hole of the connecting piece, making disassembly difficult.

The object of the present invention is to provide a picture frame, which is suitable for a picture frame, especially a temporary frame, which can firmly hold two frame members together by fastening one screw, and can be reliably dismantled by loosening the screw.

[Means to solve the problem]

An assembly fitting that is inserted between two frame members whose end surfaces abut against each other and joins the two frame members together, with an engagement hole formed in the inner piece of the frame members so that the opposite ends of the frame members A coupling and fixing plate inserted between the grooves and a coupling plate provided with a locking piece overlaid on the inner piece of the frame material and fitted and locked in the engagement hole are coupled with screws via a coil spring.

[Effect]

By tightening the screws into the engagement holes drilled in the inner piece of the frame material, the connecting plate that is aligned with this inner piece is pressed against the inner piece,
By working together with the connecting fixing plate to connect the two frame members that are butted together, and by locking the engaging pieces of the connecting plate into the connecting holes of the inner piece, the connection between the two frame members is strengthened, and in turn, the engaging pieces By loosening the screw, it can be easily removed from the coupling hole by the action of the coil spring, ensuring reliable assembly and disassembly of the frame material.

[Example] The assembly fittings of the picture frame of the present invention will be explained below based on the illustrated example.

In the figure, reference numeral 1 denotes a frame material for a picture frame that is formed into a desired cross-sectional shape according to the purpose and whose ends are cut at an angle so that they can be butted against each other. 1a and 1b are integrally formed, and a coupling and fixing plate 2 is inserted and fixed near the ends of the two frame members 1 and 1 that are butted against each other using the grooves 1a and 1b. When the frame members 1 are butted against each other, they are inserted from their ends and fixed at a predetermined position. In addition, the frame material 1 has an inner piece 1d facing the outer piece 1c.
are integrally formed, and a slit-shaped engagement hole 1e is bored in this inner piece 1d and near the end of the frame member 1.

The engagement fixing plate 2 is a single metal plate bent in a dogleg shape, and its width is equal to the opposing grooves 1a and 1b of the frame material 1.
A screw hole 21 is bored in the bent portion of the bent portion.

Further, a coupling plate 3 bent in a dogleg shape is disposed on the coupling and fixing plate 2. This connecting plate 3 is bent into a dogleg shape like the connecting and fixing plate 2, and has a hole 31 bored in the bent part, and has locks at both ends that are fitted and locked into the engaging holes 1e of the frame member 1. The pieces 32, 32 are integrally formed. This engaging piece 32 is provided protrudingly from the edge of the connecting plate,
It is also bent inward so that it can be inserted into the engagement hole 1e.

A screw 4 is passed through and screwed between the connecting plate 3 and the connecting fixing plate 2. That is, the screw 4 passing through the hole 31 of the coupling plate 3 is screwed into the screw hole 21 of the coupling and fixing plate 2. At this time, a coil spring 5 is interposed between the two plates, and the two plates are always kept apart from each other by the spring pressure.

When the two frame members 1 and 1 are butted against each other as shown in FIG. Make equal.

The coupling and fixing plate 2 and the coupling plate 3 are opposed to each other with a coil spring in between, and screws 4 are inserted and screwed between the two plates to make them integral in advance, and form the shape as shown in FIG. 2.

Then, the coupling and fixing plate 2 is inserted between the opposing grooves 1a and 1b of the frame members 1 and 1 that are butted against each other, and the coupling plate 3 is applied along the surface of the inner piece 1d. This state is shown in FIG. Next, when the screw 4 is tightened, the coupling plate 3 is pressed against the fixed coupling plate 2 while compressing the coil spring. At this time, engagement hole 1
The engagement piece 32 is inserted into e. After the engaging piece 32 is locked in the engaging hole 1e, when the screw is further tightened, the end surfaces of the frame members 1, 1 are strongly pressed against each other, and the end surfaces are joined without any gaps, and the fixed connecting plate 2 and the connecting plate 3 are connected.
The two frame members 1, 1 are firmly connected between them.

Furthermore, when the frame is dismantled, by loosening the screws, the coupling plate 3 is separated from the inner piece 1d of the frame material by the action of the coil spring, and the engagement piece 32 is completely separated from the engagement piece 1e. As a result, the joint between the two frame members 1, 1 is released.

[Effect of idea]

According to the present invention, by tightening a single screw, the two frame members that are butted against each other can be firmly connected without creating a gap, and by simply loosening this screw, the engagement piece of the connecting plate can be moved by the action of the coil spring. It can be reliably removed from the engagement hole of the frame material, and disassembly can be easily and reliably performed.
