[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a photo holder using a resin plate formed by stacking and locking two resin plates each having a frame formed by folding over two opposite sides of a square. The present invention relates to a method and a front plate and a main plate used for the holder.

[0002]

2. Description of the Related Art In a conventional photo holder using a resin plate, a card and a photograph are inserted between the front plate and the main plate and held at an arbitrary position, and only the gap between the front plate and the main plate is used in a display function. are doing. (For example, 10-120

[0003]

In a conventional photo holder using a resin plate, a card and a photograph are inserted between the front plate and the main plate, and even if the card is displayed at a predetermined position, the front plate and the main plate are displayed. Due to lack of pinching pressure related to the structure of
Had to be corrected to the original position.

The present invention uses a resin plate which is inserted between the front plate and the main plate to obtain a function of securely holding the card being displayed and the photograph by sandwiching the photo, thereby facilitating accurate formation of the frame portion. It is an object of the present invention to provide a method for manufacturing a photo holder, and a top plate and a main plate having a curved surface effective for smoothly attaching and detaching exhibits related to the above functions.

[0005]

In order to achieve the above object, the frame forming surface of the front plate forms a concave curved surface, and the frame forming surface of the main plate forms a convex curved surface. The two plates are locked with the convex faces facing each other,
The holder is assembled and configured.

[0006] The above-mentioned front plate is formed by folding a rectangular transparent hard resin plate from two opposing sides to the same surface in a horizontal U-shape with an arbitrary width, and then unnecessary portions other than a predetermined frame width. To form a pair of frames, at which point the required constant curvature is obtained for the following reasons. The tension of the bent portion generated by the folding process of the resin plate breaks the balance of inertia by cutting, and a concave curve is generated secondary to the direction parallel to the frame part, and this ripple has a constant curvature on the entire surface of the front plate There is a manufacturing method to obtain the form.

[0007] The main plate is formed by folding a rectangular hard resin plate, which has already been formed into a curved shape, from the two opposing sides in the bending direction toward the convex surface with an arbitrary width, respectively.
Unnecessary portions other than the predetermined frame width are cut off to form a pair of frames. The above-mentioned secondary curvature generated at this time is removed, and it is necessary to form a linear frame. There is a manufacturing method in which a curve in the direction opposite to the next curve is molded to cancel out.

In the step of forming the frame, as a means for facilitating a difficult processing step of accurately forming a fixed frame having a small width, the folding width is set arbitrarily wide as described above. There is a manufacturing method in which a certain required degree of curvature is accurately formed on the front plate, which is the basis of a stable card holding function at the same time by cutting off the card.

When the two sides of the front plate are fitted into the pair of frames of the main plate manufactured and formed as described above with their convex surfaces facing each other and locked and assembled, the elasticity of both plates is opposed, and the main plate comes into close contact with each other. In addition, an effective holding function works to attach and detach the exhibition card and the photo smoothly with the pressure between the front plate and the display card.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described with reference to the drawings based on embodiments. In FIG. 1, for example, a plate thickness of 0.3 mm to 1.0 mm as a transparent hard resin plate,
In a photo holder having a formed frame width of 1.5 mm to 4 mm, the sides 7 and 8 of the front plate 2 are fitted into the gaps 11 and 12 of the frames 3 and 4 of the main plate 1 with their respective convex surfaces facing each other, and locked. And assembled.

The manufacturing process for forming the main plate 1 shown in FIG. 2 is as follows: (a) First process: a transparent hard resin plate having a predetermined curved shape is prepared, and an arbitrary flat plate is formed for forming a frame. And a step of preparing an arbitrary mold having a curved surface used for correcting the secondary curvature. (B) Second step: each of the rectangular transparent hard resin plates has an arbitrary width from two opposing sides in the bending direction. A step of heating the set bending position, sandwiching a flat template, turning the sheet toward a convex surface in a horizontal U-shape, and pressing and pressing the upper surface; (c) a third step (FIG. 5): each of a horizontal U-shape Pressing the folded portion together with the template from the upper surface on the curved convex surface of the prepared mold base, heating the bent portion, and molding the bent portion into a convex curve in a direction parallel to the portion; ) Fourth step (FIG. 5): 3A of the turned back unnecessary part,
4A is cut off by a dotted line, and at this time, a process of forming predetermined linear frames 3 and 4 shown in FIG. 2 is performed.

The manufacturing process for forming the front plate 2 shown in FIG. 3 is as follows: (A) First process (FIG. 4): A bending position set to an arbitrary width from two opposing sides of a rectangular transparent hard resin plate. Heating, sandwiching a flat template for forming a frame, folding in a horizontal U-shape toward the same surface, and pressing the upper surface for molding. (B) Second stroke (FIG. 4): folded unnecessary Part 5
A, 6A is cut off along a dotted line, and the frames 5, 6 and the front plate 2 are simultaneously formed into a predetermined concave curve.

[0013]

Since the present invention is configured as described above, it has the following effects.

Since each of the main plate and the front plate is formed on its own curved surface, the functions of holding, attaching and detaching the card and the photograph of the photograph holder are remarkably improved.

By forming the main plate and the front plate on the basis of the curvature that occurs secondarily when forming the frame of the front plate, even in the manufacture of photo holders having various plate thicknesses and frame widths,
It is easy to form the optimum holding function for each.

[0016] Since the main plate and the front plate are adopted and assembled by locking the convex surfaces of the plates facing each other, a pressure for appropriately holding the card photograph is generated over the entire surface in close contact between the two plates.
It is possible to easily manufacture a photo holder using a resin plate having an effective function of preventing falling off, movement and displacement.

In the process of forming the frame, the folded portion is set to an arbitrary width, and the unnecessary portion is cut off, whereby accurate and easy production can be performed regardless of a thin frame which is difficult to work.
