Description

[Detailed Description of the Invention] The present invention relates to a picture frame in which a frame is formed by folding cardboard, plastic board, etc. around the periphery along fold lines.

As a simple picture frame of this type, a frame obtained by using two forming members is known, for example, as seen in Japanese Utility Model Application Publication No. 48-3898. However, since this method uses two flat plate members, the assembly thereof is complicated and time-consuming. The purpose of the present invention is to obtain a simple picture frame free from such inconveniences, and is composed of a flat plate member 1 and a core member 2, and the flat plate member 1 is folded through a fold 3 provided approximately in the center. It is provided with a front piece 4 and a back piece 5 which are arranged in a row, and a plurality of edge frames 7 are formed in a row between the front piece 4 and the back piece 5 through folds 6. A plurality of edge frame pieces 7 and one binding piece 9 are formed by the fold line 6 on a side 8 along the fold line 3 of the back piece 5, and the side 8
A plurality of edge frame pieces 7 and one insertion piece 11 are provided on sides 10, 10 that intersect with each other through folds 6,
The edge frame piece 7 along the fold 3 and the side 8 and the back piece 5 are bent along the folds 6 and 3 to form the edge frame 12, and the binding piece 11 and the back piece 5 or the front piece 4 are folded. and both ends of the core material 2 are inserted and fixed to the edges of the edge frames 12, 12, and the edge frame pieces 7, 7 provided on the sides 10, 10 are attached to the core along the fold 4. It is made by bending the material 2 so as to wrap it around it.

The illustrated example shows an embodiment in which an edge frame 12 having a triangular cross section is formed on the peripheral surface of a flat plate member 1. To explain this below, in the case shown in FIGS. 1 to 4, two edge frame pieces 7, 7 are connected by a fold 6 between a front piece 4 and a back piece 5, and these Two edge frame pieces 7, 7 are formed by a fold 6 on the side 8 of the back piece 5 facing the
and one binding piece 9 are successively connected, and the edge frame piece 7,
7 is bent outward along the fold line 6 to form an edge frame 12, and the binding piece 9 formed on the front piece 4 is bound to the back piece 5 by adhesive or other means. In this way, an edge frame 12 having a triangular cross section was formed at the fold 3 and the side 8. In this case, triangular ears 14 are made to protrude from both ends of the outer edge frame pieces 7 of the edge frame pieces 7 constituting the edge frame 12, and the edge pieces 14 are folded inward to reinforce the edge frame 12. At the same time, the end is inclined diagonally, and side 1
The edge frame pieces 7, 7 provided at 0, 10 are made so that they do not get in the way when folded.

The edge frame pieces 7 provided on the sides 10, 10 are each 2
The edge frame piece 7 is made into a piece with oblique edges on both sides so that when the edge frame piece 7 is folded, it does not come into contact with the edge frame 12 provided on the fold line 3 and the side 8.

Reference numeral 15 indicates protrusions provided at both ends of the inner edge frame piece 7 forming the edge frame 12 provided on the sides 10, 10, and when folding the edge frame piece 7, the protrusions 14 are inserted into the fold line 3 It is inserted into the notch 16 of the edge frame 12 provided at 8 and fixed.

As shown in FIG. 4, the core material 2 consists of a straight part 2a having a length approximately equal to the length of the edge frame 12, and a diagonal part 2c continuous to both ends of the straight part 2a through folds 2b.
An overlapping piece 2d for reinforcement was provided at the diagonal portion 2c via a fold.

Then, both ends of the core material 2 are inserted into the edge frame 12 provided along the fold line 3 and the side 8, and the edge frame pieces 7
When inserting the insertion piece 11 into the lower surface of the core material 2 after folding it inward so as to wrap around the core material 2, insert the insertion piece 11 into the notch 16 of the projection piece 15. It is fixed in a stable state by fitting.

A gap is formed between the insertion piece 11 and the front piece 4 on the lower surface of the edge frame 12 provided on the pieces 10, 10, and a photograph, a painting, or a transparent plate that overlaps the surfaces thereof is inserted into the gap. It can be installed by wearing it.

In the illustrated example, two edge frame pieces 7 are provided along each side 8, 10, 10 and the fold line 3 through the fold line 6 so that the frame frame 12 has a triangular cross section. When the number of edge frame pieces 7 is three, the edge frame 12 may have a rectangular cross section. 1 in drawings
Reference numeral 7 designates a locking hole provided on the back piece 5 for hanging the picture frame on a nail or the like. Further, in the above-mentioned one, a plurality of edge frame pieces 7 are formed on the side 8 along the fold line 3 of the back piece 5 by the fold line 6.
and one binding piece 9 was formed, but as shown in FIG. 9 can also form a similar picture frame.

In this way, according to the present invention, a picture frame can be easily formed by simply folding along the fold, and the front piece 4 and the back piece 5 that are connected to one flat plate member 1 through the fold 3 are formed. Since it has a double structure with front and back pieces 4 and 5, a relatively robust product can be obtained. Insert both ends of the core material 2 into the ends of the edge frames 12, 12, and bend the edge frame pieces 8 and the insertion pieces 11 inward so as to wrap around the core material 2, and attach them to the bottom surface of the core material 2. Since the inserting piece 11 is inserted, a gap can be formed between the inserting piece 11 and the front piece 4 to insert a photograph, etc., so that it is easy to attach a photograph, etc. to the frame. There is an effect that can be obtained.
