DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a picture frame in which a photograph, a picture, a product, and the like are inserted.

[0002]

2. Description of the Related Art Photographs and paintings can be inserted and
There are wooden, metal, and synthetic resin frames on the stand. The synthetic resin frame is integrally molded, but the wooden and metal frames are two vertical frames and two vertical frames. The rectangular frame is formed by cutting both ends of the horizontal frame into 45 ° inclined surfaces, joining the inclined surfaces together, and joining them with an adhesive or a fixture. Some frames are made of cardboard such as a chip board, but are basically assembled in the same manner as a wooden board.

[0003]

Therefore, when assembling, it is necessary to position and join the inclined surfaces of the vertical frame and the horizontal frame, which is difficult to position, requires a large number of assembling steps, and increases the cost. Was the cause.

[0004] The present invention has been made in view of the above-mentioned circumstances, and its object is to assemble it easily.
An object of the present invention is to provide a method for manufacturing a frame that can be assembled without requiring skill and can reduce costs.

[0005]

According to the present invention, in order to achieve the above-mentioned object, a first aspect of the present invention is to provide a belt-like body made of cardboard, which is provided with two strips along the longitudinal direction of the belt. A first step of providing a V-shaped groove at a distance from each other, forming a bottom portion at an intermediate portion in the width direction of the band-shaped body, and forming side portions on both sides of the bottom portion; As a fulcrum, both sides are vertically valley-folded with respect to the bottom, and a band-shaped piece having a width narrower than the one side is interposed and bonded between both sides, and a band-shaped frame material having a concave groove on one side edge is formed. A second step of forming, and cutting the frame material into a V-shape at a predetermined interval on one side edge having a concave groove, forming a corner portion,
A third step of alternately and continuously forming vertical frames and horizontal frames between the corner portions, and bending each of the corner portions of the frame material at a right angle with the concave groove inside; And a fourth step of connecting the frames. Claim 2
The fourth step of the first aspect is characterized in that each corner is bent at a right angle while an edge of a rectangular mount is inserted into a concave groove of a frame material.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a frame material. Reference numeral 1 denotes a band made of cardboard such as a chip board (for example, having a thickness of 2 to 3 mm). An intermediate portion in the width direction of the band 1 extends in the longitudinal direction of the band 1. Two V-shaped grooves 2 are provided apart from each other. A narrow bottom 3 is formed in the middle of the band 1 in the width direction, and side portions 4 are formed on both sides of the bottom 3.

The belt-like body 1 has a bottom 3 with a V-shaped groove 2 as a fulcrum.
The both sides 4 are vertically folded in a valley, and a band 5 made of the same material as the band 1 is interposed between the both sides 4.
Is adhered to the inner surface of the side portion 4 with an adhesive to form a band-shaped frame material 6. Since the strip 5 is narrower than the one side 4, a groove 7 is formed on one side edge of the frame material 6.

Further, one side edge of the frame material 6 having the concave groove 7 is cut into a V-shape at a predetermined interval to form a corner portion 8. That is, although the cut of the corner portion 8 reaches the bottom portion 3 from the side portion 4, the skin 3a of the bottom portion 6 remains, so that vertical frames 9a, 9b and horizontal frames 10a, 10b are provided between the corner portions 8. They are formed alternately and continuously.
The angle of the corner portions 8 at both ends in the longitudinal direction of the frame material 6 is 4
At 5 °, the angles of the three corner portions 8 at the intermediate portion are formed at 90 °.

Next, a case where the picture frame is assembled using the picture frame material 6 and the rectangular mount 11 will be described. As shown in FIG. 2, the vertical edge 11a of the mount 11 is formed by the concave groove of the vertical frame 9a of the picture frame material 6. Insert into 7. Next, the corner portion 8 is bent at a right angle, the horizontal edge 11b is inserted into the concave groove 7 of the horizontal frame 10a, and the corner portion 8 is bent at a right angle in the order of the horizontal frame 10b and the vertical frame 9b, and the concave portion is similarly formed. By inserting into the groove 7, the periphery of the backing material 11 is surrounded by the frame material 6, and finally, the corner portions 8 at both ends of the frame material 6 are joined and bonded to form a frame as shown in FIG. 12 is assembled.

An adhesive surface 13 is formed on the surface of the mount 11, and a transparent film 14 is adhered to the adhesive surface 13 so as to be peelable. Therefore, the photograph and the painting can be protected by peeling the transparent film 14 and inserting the photograph and the painting, and covering with the transparent film 14,
This frame 12 can be raised on a wall or leaned against a stand.

Next, the manufacturing sequence of the frame will be described. Two V-shaped grooves 2 are formed in the widthwise middle part of the cardboard 1 in the width direction and are spaced apart from each other. , A bottom portion 3 is formed at a middle portion in the width direction, and side portions 4 are formed on both sides of the bottom portion 3. Next, the V-shaped groove 2
Is vertically bent with respect to the bottom 3 with respect to the bottom 3, and a strip 5 is interposed and bonded between the both sides 4 to form a strip-shaped frame material 6 having a concave groove 7 on one side edge. .

Next, one side edge of the frame material 6 having the concave groove 7 is cut into a V-shape at a predetermined interval to form a corner portion 8, and a vertical frame 9a, 9b and the horizontal frames 10a and 10b are formed alternately and continuously. Next, the corners 8 are bent at a right angle while inserting the edges 11a and 11b of the backing material 11 into the concave grooves 7 of the frame material 6 and finally the both ends of the frame material 6 are connected to complete.

[0013]

As described above, according to the present invention, the frame material is a single continuous member, and the V-cut corners are formed at predetermined intervals, so that assembly is possible. It is simple, can be assembled without requiring skill, and has the effect of reducing costs.
