Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a thin plate end locking structure applied to, for example, a lid locking structure of a synthetic resin case for accommodating a plurality of sheets or film for organizing photographs.

[0002]

[Prior art]

 Conventionally, in a case or the like formed of a synthetic resin thin plate, various types of locking structure between the main body of the case and the lid are provided according to the intended use of the case, etc. In consideration of the appearance design of the case, the locking structure is made compact.

[0003] Such a locking structure will be specifically described by way of example. As a typical example thereof, a structure in which a case body and a lid are locked by a hook is known. The hook locks one metal fitting having a concave portion and the other metal fitting having a convex portion by fitting both of the concave and convex portions. Also known is a case in which the main body of the case and the lid are locked by a surface fastener. The surface fastener is one in which a large number of hook-shaped linear bodies are planted on the surface of one cloth-like body and a large number of ring-shaped linear bodies are planted on the surface of the other cloth-like body. The linear body and the ring-shaped linear body are brought into pressure contact with each other to be locked. Further, a locking portion made of a thin plate is formed on one of the main body of the case and the lid, and a tongue piece is formed on the other side, and the tongue piece is engaged with the locking portion to lock both. Things are also known.

[0004]

[Problems to be solved by the device]

 However, the locking structure as described above has the following problems. First of all, according to the locking structure by the hook, when the one metal fitting and the other metal fitting forming the hook are locked, it is necessary to strongly press these metal fittings to each other, so that the pressing operation is performed. It is premised that the main body and lid of the case have a strong structure so that they will not be deformed by the pressing force when they are carried out.For example, when the case is composed of a thin plate made of synthetic resin. However, when the pressing operation is performed, the case body and the lid body are deformed, and the engagement is not properly performed. Further, since the hook has to be obtained separately when manufacturing the case, there is a problem that the locking structure is relatively expensive.

Further, according to the locking structure using the surface fastener, as an unavoidable problem of the surface fastener, the locking force is weak, and particularly when fine particles or dust adheres, the locking force is extremely weak. Therefore, there is a problem in that the engagement between the case body and the lid body is inadvertently released.

Further, according to the structure in which the locking portion and the tongue piece are provided on the thin plate, the tongue piece is engaged with the locking portion of the thin plate, that is, the tongue piece is locked on the entire locking portion of the thin plate. Because of the configuration, for example, when the locking portion is formed in close contact with the main body of the case, the locking operation of the tongue piece with respect to the locking portion must be carefully performed, and the locking operation can be performed easily. There was a problem that it could not be stopped.

The present invention has been made in view of the above circumstances. For example, the case main body and the lid can be easily and reliably locked, and the case locking structure can be inexpensive. It is an object of the present invention to provide a thin plate end locking structure that can be manufactured.

[0008]

[Means for Solving the Problems]

 The thin plate end locking structure of the present invention is a thin plate end locking structure in which one thin plate end and the other thin plate end are superposed and the thin plate ends are locked to each other. An engaging thin plate portion is formed on the outer surface of the end portion, the end edge of which faces the direction opposite to the extending direction of the thin plate end portion, and which has a cut extending from the substantially central portion of the end edge in the extending direction. The inner surface of the other thin plate end portion is formed with a tongue piece that projects in a direction opposite to the extending direction of the thin plate end portion and that can be locked to the locking thin plate portion.

[0009]

[Action]

 The locking structure of the thin plate end portion of the present invention is such that the tongue piece is locked to the locking thin plate portion and both are joined. Further, in the present invention, since the cut thin plate portion is formed with the cut extending from the substantially central portion of the edge toward the extending direction of the thin plate end portion, the tongue is locked to the whole lock thin plate portion. Not only this, by utilizing this cut, the tongue piece can be locked by slightly raising the half of the locking thin plate portion (one part divided by the cut). Therefore, since the locking can be performed by any of the above methods, the locking operation can be easily performed.

Further, since the locking thin plate part or the half part is locked by a simple operation, that is, the entire locking is always performed, the locking can be surely performed. is there.

【Example】

 Embodiments of the thin plate end locking structure according to the present invention will be described below in detail with reference to the drawings. FIG. 1 shows an embodiment in which the present invention is applied to a photo organizing case. In FIG. 1, reference numeral 1 is a photo organizing case, and reference numeral 2 is a photo organizing film mounted in the photo organizing case 1.

The photo organizing case 1 is formed by bending a thin strip of synthetic resin, and is bent into a rectangular cross section so that the folded photo organizing film 2 is bundled around. . In this photo organizing case 1, the tongue piece 6 formed on the lid 5 is engaged with the locking thin plate portion 4 formed on the main body 3 to lock the lid body 5 (thin plate end portion) on the main body 3. It is like this.

Details of the locking structure are as follows. First, the main body 2 of the photo organizing case 1 has a double structure in which an end portion (thin plate end portion) 3a is made up of an inner surface portion 7 and an outer surface portion 8 by folding back the thin plate. A first cut 9 is formed on the outer surface portion 8 along the edge 3b of the end 3a, and the extending direction (X) of the end 3a from the substantially central portion of the first cut 9 is formed. A second cut 10 extending in the (direction) is formed. In this structure, a fixed region in the extending direction of the end portion 3a from the first cut 9 constitutes the locking thin plate portion 4. That is, the locking thin plate portion 4 has its edge (the edge formed by the first cut 9) facing in the direction opposite to the extending direction of the end 3a, and the approximate center of the edge. It is a portion having a second cut 10 extending from the portion in the extending direction, and includes a right half 11 and a left half 12 divided by the second cut 10.

Further, the tongue piece 6 formed on the end portion 5a of the lid body 5 is formed with holes 14 and 15 at regular intervals along the edge 5b of the end portion 5a, and between the holes 14 and 15. It is formed by cutting a semicircular third cut 16 into the. The tongue piece 6 projects from the lid body 5 in a direction opposite to the extending direction (Y direction) of the lid body 5 and can be locked to the locking thin plate portion 4.

The film 2 is obtained by welding two transparent films at regular intervals so that a photograph can be inserted between the fused films. In FIG. 1, the film 2 is shown in a folded state.

Next, a usage example of the photo organizing case 1 having the above-described configuration will be described. When inserting / removing the photo into / from the photo organizing case, or when viewing the inserted photo, as shown in FIG. 2, attach the tongue piece 6 in the state shown in FIG. It is inserted into the space formed by the inner surface portion 7 and the lower surface portion 8 from the end edge, and is locked to both the right half portion 11 and the left half portion 12. In this state, since the lid body 5 is formed integrally with the main body 3, when it is stopped from the state shown in FIG. 1 to the state shown in FIG. Is urged to. Therefore, the locking of the tongue piece 6 is not easily released, and the tongue piece 6 is firmly locked.

On the other hand, FIG. 3 shows a state of use different from that in FIG. 2. In FIG. 2, the tongue piece 6 of the lid body 5 is not locked to both the right half portion 11 and the left half portion 12. However, this is an example of the case where the right half 11 is slightly raised by utilizing the second cut 10 and the tongue piece 6 is locked to the right half 11. Even in this case, since the elastic force acts in the direction of the arrow Y, the lid 5 and the main body 3 are firmly locked and cannot be easily released.

Therefore, in the above-mentioned photograph organizing case 1 using the locking structure of the present invention, when the tongue piece 6 is normally locked to the locking thin plate part 4, either the right half part 11 or the left half part 12 is used. On the other hand, both of them can be locked easily and firmly.
