Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a picture frame, and particularly to a frame for a picture frame that is small and suitable for being placed on a desk, a mantel, or the like.

[Prior art] An exhibit is sandwiched between a pair of transparent plates such as glass plates or synthetic resin plates, and the four circumferences of the exhibit are simply held elastically by a frame material with a substantially circular or square cross section and a portion cut out. Picture frames are well known.

Furthermore, it is also well known that grooves are provided on the front and back surfaces of a pair of overlapping transparent plates along their peripheries, and the leading edges of both side edges of the frame material are fitted and locked into the grooves. .

[Problems to be solved by the invention] In such conventional devices, the frame material may separate from the transparent plate due to external force, for example, if it is dropped, so it is difficult to securely grip the periphery of the transparent plate. There were some problems.

The present invention was devised in view of the problems of the prior art as described above, namely, a freely assembleable frame designed to prevent the frame from separating from the transparent plate as much as possible and to securely hold the exhibit. We provide frames for picture frames.

[Means for Solving the Problems] In order to achieve the above object, the frame for a picture frame in the present invention is made of a synthetic resin material and includes two side plates that sandwich the periphery of a pair of superposed transparent plates;
The frame is constructed from four frame materials made by integrally molding a partition wall with a locking bulge on the top edge and a bottom plate with an E-shaped cross section. In addition, opposing grooves are provided along the periphery to allow the bulging edge to pass through.

[Function] In the frame of the present invention having the above structure, in order to fit each frame member into the opposing grooves of the superposed transparent plates, it is necessary to move from the end of the frame member along the grooves on the transparent plate side. The frame material is slidably fitted from the end thereof, and the bulging edges of the side plates and the partition reliably prevent the frame material from separating from the transparent plate.

In particular, when the bulging edge is provided with a right-angled step, the elasticity of the side plates together with the frame material will not be separated from the transparent plate even if a considerable impact is applied.

On the other hand, the installation and removal of this frame material is done by slidingly inserting the four frame materials in order, so that at the corners where each frame material meets at right angles, Assembling and butting the four frame members is done gradually in order as described below, leaving a slight margin between the mutual abutting surfaces. Similarly, when removing the four frame members, By sequentially moving the book frame materials in one direction little by little, a hole is created in a desired corner where one of the frame materials can be removed, and once one is removed, the other three will slide easily. Can be made to leave.

Hereinafter, the gist of the frame of the present invention will be explained based on the embodiment shown in the drawings.

[Example] In Figs. 1 to 3, reference numeral 1 denotes a frame for a picture frame consisting of four frame members 2 made of a synthetic resin material, etc., and opposing side plates 4, 4 of a bottom plate 3 are integrally formed. It is made of a synthetic resin material, and a partition wall 5 is provided at the center of the inside of the bottom plate 3 along the length of the frame material 2.
The top edge of the partition wall 5 has a bulging edge 6 for locking with a square cross section.
These components are continuously formed into an E-shaped cross section by extrusion molding, and this is cut into a desired length to be used as the frame material 2.

Next, 7 and 7' are a pair of transparent plates made of glass plates or synthetic resin plates, which are superposed on each other as shown in the third figure, and an exhibit, for example, a photographic plate 10, is sandwiched between them. Concave grooves 8, 8' are provided on the abutting surfaces of the plates 7, 7' and along the periphery thereof,
Both are overlapped to form a through hole 9, into which the locking bulge 6 on the frame member 2 side can be slidably fitted.

Therefore, as shown in FIG. 3, when the photographic plate 10 is sandwiched between transparent plates 7 and 7' such as glass plates, a gap d is created around the periphery due to the thickness of the plate. 6 into the grooves 8, 8'.

Therefore, the four frame members 2 are inserted at both ends of each frame member 2 so that the four members are first inserted in a swastika shape as shown in Figure 5, and then the four members can be sequentially moved little by little to the proper position. The frame members 2, 2, . . . are moved one after another to their respective normal positions.

Therefore, when completed, there will be some loosening at the four corners of the frame, but this will not cause any practical problems and will not cause any discoloration in terms of appearance.

Next, when removing the frame materials, contrary to the above, use the slack mentioned above to move them one by one to give room for pulling out one corner of the frame, and if you remove one frame material, the other three will be removed. It can be removed easily.

Assembling and disassembling are performed as described above, and after the assembly is completed, the transparent plates 7, 7' such as glass plates are sandwiched around the four sides by the side plates 4, 4 of each frame member 2, as shown in the third figure. At the same time, in the through hole 9 formed by the concave grooves 8, 8', the bulging edge 6 locks the concave grooves 8, 8', respectively, using its stepped portion 6a, so that a considerable amount of water is generated. It can withstand strong impacts.

[Effects of the invention] As described above, the present invention consists of a pair of side plates that sandwich the periphery of two overlapping transparent plates with an exhibit between them;
A frame for a picture frame is constructed by four frame members made of a synthetic resin material or the like and integrally molded to have an E-shaped cross section and a bottom plate and a partition wall having a bulging edge for locking that is inserted into a concave groove provided on the periphery of the transparent plate. By doing so, the detachment of the picture frame from the transparent plate is prevented as much as possible, and the exhibits are securely held, resulting in excellent rigidity and durability, which is extremely useful in practice.
