Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an improvement in rectangular picture frames provided for paintings, illustrations, photographs, etc.

(Prior art) Conventionally, this type of rectangular picture frame was manufactured using
As described in the publication, a single strip plate with joining hypotenuses having an angle of 45° at each end is formed with chevron-shaped notches each having an opening angle of 90° at three locations at required intervals. In some cases, the chevron-shaped cut portions are bent and merged using the connecting portion as a fulcrum, and the oblique sides of both ends are adhered to form a rectangular frame of a certain size.

(Problem to be solved by the invention) However, although the above-mentioned conventional technology is convenient because it can easily form a picture frame, it can only be formed into a frame of a certain size. This has the inconvenience of having to purchase a picture frame to match the size of the picture frame, or a painting, etc. to fit the picture frame.

Furthermore, if there is a size error when purchasing a picture frame, there is a risk that the picture frame will not match the balance of the picture, etc., and that a picture frame that fits the picture, etc. will have to be purchased again.

Furthermore, even on the manufacturer's side, the current situation is that they have to manufacture various sizes, resulting in increased costs.

In addition, as a solution to this problem, Jikoaki
As described in Publication No. 50-31276, a required number of assembly units each having a latching protrusion on one side and a latching recess into which the latching protrusion fits on the other side are used. There is a picture frame that can be formed into a rectangular shape of a required size to correspond to the size of a painting, etc. by fitting and latching the retaining recessed part, but in this case, as the frame to be formed becomes larger, there are many In addition to requiring multiple assembly units, the connection work between the individual assembly units also requires multiple steps, which becomes more labor-intensive as the size increases.

The present invention was devised in view of the problems of the prior art, and its purpose is to provide an outer frame material for picture frames that is provided with grooves that can be divided according to the size of paintings, etc. To easily form rectangular picture frames for paintings of various sizes, regardless of their size, using a single outer frame material.

(Means for Achieving the Object) The technical means of the present invention to achieve the above object is a hollow elongated rigid member having openings at both ends and having an inclination of 45° with respect to the longitudinal direction. This is because the grooves are arranged in a zigzag pattern.

(Function) By using the above-mentioned technical means to select and divide the appropriate grooves according to the size of the painting, etc., and connecting each end to each other, a rectangular picture frame of the required size that matches the size of the painting, etc. is formed.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

In the figure, A is an outer frame material for a picture frame, and the outer edge material A is a long rigid member 1 formed in a hollow and elongated shape from wood or synthetic resin, etc., and a groove 3'' on the back side thereof that communicates with the hollow portion 3'. to form a T-groove 3 together with the hollow part 3',
In addition, grooves 2 are provided on both the front and back surfaces of the long rigid material 1.

The dividing grooves 2 are made so that the outer frame material A for the picture frame can be divided at appropriate points, and are carved at an inclination angle of 45° with respect to the longitudinal direction of both the front and back surfaces of the long rigid material 1. do.

The T-slot 3 extends in the longitudinal direction of the back surface of the long rigid material 1,
A groove 3'' narrower than the hollow portion 3' is provided so as to communicate with the hollow portion 3', and the cross section is approximately T-shaped together with the hollow portion 3'. The head of the wall 7 is inserted into the wall 7 so that it can be riveted to the wall 7.

In the figure, reference numeral 4 denotes an L-shaped connector, which is used to connect the corner parts by making the respective ends of the divided outer edge material 4 face each other.

Next, to explain how to assemble a picture frame using the outer frame material A of this embodiment, first, the outer frame material A is cut into suitable grooves 2... Select and divide to create side plates of required length.
Form 4 sheets of A ₁ ....

Then, fit an appropriate number of thumbtacks 6 into the T-grooves 3 of each side plate _A1 ..., and then make each end of each side plate _A1 face each other so as to form a 90° corner,
Fit the connectors 4 into the T-grooves 3, combine them into a rectangular shape, press them against the wall 7 so as to surround the periphery of the picture 5 pasted on the wall 7, and fix it with the pushpins 6 (fourth figure).

In this embodiment, the painting 5 is pasted on the wall 7 in advance and fixed so as to enclose its periphery, but a desired panel (not shown) is prepared separately and the painting 5 is pasted on the wall 7 in the rectangular shape. The painting 5 may be held and fixed between the formed picture frame and its panel, and then attached and fixed to the wall 7.

(Effect of the invention) Since the present invention has the above-mentioned configuration, it is possible to divide a piece of outer frame material by selecting appropriate grooves according to the size of the picture, etc., and connect each end. For example, since a picture frame that matches the size of the painting, etc. is formed, the hassle of having to purchase a picture frame, etc. according to the size of the painting, etc., or a picture, etc., according to the size of the picture frame, etc. is eliminated. It is convenient because rectangular picture frames of various sizes can be easily formed regardless of their size.

[Brief explanation of the drawing]

FIG. 1 is a plan view of the outer rim material for a picture frame according to the first embodiment;
Fig. 2 is a three-dimensional view showing the outer frame material in a folded state, Fig. 3 is a partially cutaway enlarged view showing the combination of side plates, Fig. 4 is a front view showing the attached state, and Fig. 5
The figure is an enlarged sectional view taken along the line - in FIG. 4. In the figure, 1... long rigid material, 2... split groove, A... outer edge material for picture frame, A ₁ ... side plate.
