Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a frame connector for assembling frames by connecting frames.

[Conventional technology]

The conventional forehead frame connector C has a presser spring 13 attached to a corner portion 12a on the back side of a frame connector base 12 which is L-shaped as a whole and has an L-shaped cross section, as shown in FIG. A support part 14 is provided, and a locking pawl 16 that engages with the locking groove 15 of frames A and B is provided on the left and right sides of the support part 14, respectively, and a locking claw 16 that engages with the locking groove 15 of the frames A and B is provided near the locking pawl 16 from the locking groove 15. It has a structure in which a removal claw 17 for removing the retaining claw 16 is provided.

Then, using the frame connector of such a frame, insert one side and the other side of the frame connector base 12 into the guide grooves 18 of the frames A and B, respectively, and fit the frame into the locking groove 15 formed in the frames A and B. The frame is assembled by connecting the frames A and B by engaging the locking claws 16 of the connector.

Also, when replacing the picture in the frame, remove the claw 17.
Press with your finger to remove the locking claw 16 from the locking groove 15,
Frames A and B are separated from frame connector C, replaced with other pictures, and then frames A and B are connected using frame connector C in the same manner.

[Problem that the invention attempts to solve]

By the way, to remove the frames A and B when replacing this picture, push down the release claw 17 to remove the locking claw 16 from the locking groove 15, and then push out the release claw 17 in the same way. Frames A and B cannot be removed unless they are pulled apart from frame connector C. However, it is difficult to simultaneously apply force in different directions to push down and push out the removal claw 17 with one finger (thumb). Therefore, the frame can be removed smoothly and quickly when replacing the picture. There was a problem that was not addressed.

Also, on the side of the locking claw 16 of the frame connector C,
A cut slit 18 is provided, which causes cracks to easily form, resulting in a problem of weak strength.

[Purpose of invention]

This invention was devised to solve the above-mentioned problems, and its purpose is to make it possible to remove the frame smoothly and quickly when replacing documents, and to connect the frame with high strength so that cracks do not easily occur. It is to provide the ingredients.

[Means for solving problems]

The structure of the present invention to achieve the above object is that, in a frame connecting tool for assembling frames by connecting frames, locking claws that engage with locking holes in the frame are provided at both ends of the back surface of the base of the frame connecting tool. At the same time, a reinforcing plate is integrally provided between both ends of the back surface portion, which also serves as a removal claw to remove the locking claw from the locking hole, and an extrusion claw is provided at the corner of the base of the frame connector to separate the frame from the frame connector. This is a characteristic feature.

[Effect of invention]

With the above configuration, the pad of your finger (thumb) pushes down the reinforcing plate that also serves as a release pawl to remove the locking pawl from the locking hole, and at the same time the extrusion pawl is pushed out with the tip of your finger (thumb) to connect the frame to the frame connector. It can be easily separated from the

[Example of idea]

Hereinafter, the present invention will be explained in detail with reference to the drawings. Figure 1 shows an embodiment of the forehead frame connector according to the present invention.
FIG. 2 shows a state in which the frames are connected using the frame connecting tool.

A and B are a vertical frame and a horizontal frame of the forehead, and a locking hole 11 is formed in the back surface 10 of the frame. 1 is frame connector C
The base of the frame connector is L-shaped as a whole and has an L-shaped cross section. At both ends of the back surface 2 of the frame connector base 1, locking claws 4 protruding into rectangular shapes that engage with rectangular locking holes 11 formed in the back surfaces 10 of the frames A and B are provided. ing. Each of the locking pawls 4 projecting in a rectangular shape is inclined to become lower toward the center of the corner so that it can be easily inserted into the locking hole 11 and easily removed when removed. Round projections 5 are provided on the end surfaces of the back surface 2 and the side surfaces 3 of the frame connector base 1 to eliminate the clearance between the frame connector C and the frames A and B. Between both ends of the back surface part 2 where the locking claw 4 is provided, there is an L that also serves as a removal claw for removing the locking claw 4 from the locking hole 11 when replacing the calligraphy or painting in the frame, which will be described later.
A letter-shaped reinforcing plate 6 is integrally provided on the back surface portion 2. The reinforcing plate 6, which also serves as a removal claw, is a reinforcing plate with a stepped portion 6a, and when removing the frames A and B from the frame connector C, place the pad of your finger (thumb) F on the stepped portion 6a, which serves as a stand, and press downward. It has become easier to push down.

A presser spring 7 is integrally provided at the center of the reinforcing plate 6 with the end portion 6a, and is designed to support a foam board or the like (not shown) provided on the back side of the frame. Furthermore, a push-out pawl 8 is provided at the corner portion 1a of the frame connector C for separating the frames A and B from the frame connector C when replacing a calligraphy or drawing. Extrusion claw 8
is made up of a triangular reinforcing plate 8a and an L-shaped protrusion 8b for extrusion, and serves as an extrusion claw that also serves as reinforcement. This makes it easy to push out by bringing it into contact with the protrusion 8b.

Then, using the frame connector C, insert one side and the other side of the frame connector base 1 into the guide grooves 9 of the frames A and B, respectively, and connect the frames to the locking holes 11 formed in the frames A and B. The frame is assembled by connecting the frames A and B by engaging the locking claws 4 of tool C, respectively.

According to such a frame connector C, a reinforcing plate 6 which also serves as a removal claw for removing the locking claw 4 from the locking hole 11 is provided between both ends of the back surface 2 of the frame connector base 1, and the corner of the frame connector base 1 is Since a push-out claw 8 is provided in the portion 1a to separate the frames A and B from the frame connector C, the reinforcing plate 6, which also serves as a claw, can be removed with the pad of a finger (thumb) F when switching between calligraphy and drawings, as shown in FIG. At the same time, press down to remove the locking claw 4 from the locking hole 11, and push out the push-out claw 8 with the tip of your finger (thumb) F to separate the frame A or B from the frame connector C at the same time. Frames A and B can be easily removed. In other words, even if the applied force is applied in a different direction, the pad of the finger (thumb) F pushes down the reinforcing plate 6 that also serves as the release claw, and at the same time, the tip of the finger (thumb) F pushes out the push-out claw 8 to lock the locking claw 4. Remove it from the locking hole 11,
At the same time, the frames A and B can be pulled apart from the frame connector C to smoothly remove the frames A and B.

Furthermore, since the frame connector C is not provided with any slits or the like, cracks are less likely to occur, thereby increasing the strength and durability. The present invention is not limited to the above-mentioned embodiment, but the reinforcing plate 6 which also serves as a removable claw provided between both ends of the back surface portion 2 may be flat without the stepped portion 6a, as shown in FIG. It goes without saying that the extrusion pawl 8 provided at the corner portion 1a of the frame connector base 1 may be without the reinforcing triangular plate 8a, and that the invention can be implemented without departing from the technical idea of the present invention.

[Effect of idea]

As described above, according to the present invention, the frame can be removed smoothly and quickly when replacing calligraphy or paintings, and a strong and durable frame that is resistant to cracking can be obtained.
