Description

[Detailed Description of the Invention] Industrial Field of Application: The present invention relates to an improvement in a leaf binding unit mainly for photo albums, etc., which is constructed by stitching together transparent bag-like leaves.

Conventional technology: Conventionally, a transparent synthetic resin film is formed into a bag shape, or a paperboard is coated with multiple strips of adhesive, the top surface of which is covered with a transparent synthetic resin film, and photographs, etc. are placed between the film and the paperboard. When it comes to albums (files) made of bound leaves that are covered with the film and pasted with photographs, various methods are available for binding each leaf together with the cover. Although it has been proposed and put into practical use, in cases where a relatively large number of sheets are to be bound, spacers 10' are generally used, as shown in FIG. As shown in the figure, the edges are surrounded by the binding cover piece 20 which becomes the spine when the required number of sheets are overlapped, and the covers 21, 21 each have separate sheets, and are folded into the folded edge of the binding cover piece 20. Part 20'
Fold in the connecting piece 21' which is approximately the same width as the
Insert the binding pins 5 of the required length into the binding holes pre-drilled in each of the leaf 4, the spacer 10', the folding clamp part 20' of the binding cover piece, and the connecting piece part 21' of the cover. , a method is adopted in which a flat head screw 5' is screwed into a screw hole provided at the shaft end of the pin 5 for fastening.

According to this method, it is necessary to assemble the leaves and spacers by sequentially overlapping them and inserting them into the binding holes of the binding pin, which is time-consuming, and also leaves the upper and lower ends of the binding section open. Due to the binding structure, if the binding cover is flexible, the back will bend, and if the cover is hard, the binding width will be constant, so the combination of spacers and leaves is not suitable. There are problems such as not being able to match the binding width, resulting in unstable binding.

Purpose of the invention: The present invention solves these problems and provides a leaf binding method for albums, etc., which is structured so that the leaf binding operation is easy, the leaves are stapled in a stable state, and the appearance is beautiful. The goal is to provide a mechanism.

Structure of the invention: In this invention, in a file binding structure in which a plurality of leaves are bound with a structure that is surrounded by a transparent synthetic resin film and can store photographs, etc., the binding is attached integrally or integrally with the file cover. The member is bent into a U-shape and has appropriate rigidity, and the longitudinal ends of this binding member are bent into three sides with a size that fits inside the binding member, and the above-mentioned is attached to both bent portions. Each end cover piece is provided with a notch that engages and locks a known binding pin that binds the leaf binding portion inserted into the binding member, and the end cover pieces and the binding member form a box-shaped shape. First, a paperboard spacer that forms the binding section and has a cutout with an inclined side that is shorter than the internal length of the separately prepared box-shaped binding section and that engages with each binding pin is placed inside the binding section. A plurality of leaves are inserted from the outside between the leaves that are bound together, and the notches are engaged with the respective binding pins, thereby fixing the leaves between the binding members without being stuck.

In the notch of the spacer used in the present invention, a pin engagement hole is arranged on the longitudinal center line at a position that matches the pitch of the binding pin, and a triangular shape that connects to the pin engagement hole from one side. The spacer is provided with a notch, and preferably all the inclination angles of one side of the notch are the same, so that the spacer can be smoothly inserted between the leaves when inserted from the outside.

Embodiment: Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings. What is shown in FIGS. 1 to 5 is a photo album, and the cover 1 and spine 1' are bound with thick paperboard. This type is integrally formed by bonding a binding member 2 to the inner surface of the spine portion 1', and the binding member 2 is designed so that the paperboard can be bent into a U-shape to the required dimensions. , Binding holes 3 are drilled in the double-folded binding parts 2', 2', other than the part glued to the inner surface of the spine part 1', so that the binding holes 3 match with each other at the required pitch, and the leaves 4 to be bound are
is formed into a bag shape from a transparent synthetic resin film, for example, a polypropylene resin film, and the binding portion 4' has binding holes 4 at the same pitch as the holes provided in the binding portion 2' of the binding member 2. '' are used.

A binding pin 5 is attached to the binding hole 3 of the binding member 2.
(This is a well-known type with a flat head and a diameter larger than the stem, and a screw hole is drilled in the center of the pin end.) (Three pins in the example) are inserted, and the leaf 4 are fitted into each of the binding holes 4'' for binding, and a set screw 5' with a large head is screwed into the screw hole of the pin in advance at the end of the binding pin 5 to fix it.
The leaves 4 are designed to prevent them from coming off at the binding section, and both longitudinal ends of the binding section 6 are bent in a long U-shape as shown in FIG. Notches 7'', 7'' are formed in both bent pieces 7', 7' to engage and lock with the binding pin 5, respectively, with dimensions matching the dimension W between the binding parts 2', 2'.
Attach the end cover pieces 7 (which may be provided with pin insertion holes) by engaging the locking notches 7'' and 7'' with the binding pins 5, respectively, and stitch in this attached state. The binding section 6 is formed into a box shape by the sections 2', 2' and the end cover pieces 7, 7. In this state, the outer end of the end cover piece 7 is aligned with the end of the binding member 2.

The spacer 10 for fixing the binding part 4' of each leaf 4 to the leaf binding part of the album (file) constructed in this way is made of paperboard of an appropriate thickness, and the fourth
As shown in the figure, the outer dimensions are slightly smaller than both the length and height (depth) of the binding section, and locking holes 11 are formed on the center line at intervals that match the pitch of the binding pins. A locking notch 12 in which triangular notches are connected from one side is provided as required, and the inclined surfaces 12' of each of the notches 12 are substantially uniform.

In the present invention having such a configuration, the leaf 4
When binding, open one side of the binding member 2, align the binding part 4' of the leaf with the pin 5 and the binding hole, and staple the required number of sheets. Close the opened binding part 2' (fit the binding part 4' of the leaf to the screw hole of the binding pin). (screw the fastening screws), and lock the end cover pieces 7, 7 by aligning their locking notches 7'' with the binding pin 5 (if there is a hole, insert the pin and assemble), and the binding part is After the spacer 10 is formed into a box shape, the spacer 10 is inserted between the leaves so that its notch 12 engages with the binding pin 5, and at this time, the spacer 10 is inserted every other leaf or every 2 to 3 leaves. By filling the binding section with the spacer, the binding section 4' of the leaf 4 is fixed to the binding section.If necessary, the binding section 4' of the leaf 4 can be fixed more firmly by tightening the fastening screw. Since the notch 12 of 10 has an inclined surface 12', insertion can be easily performed by pushing the inclined surface along the binding pin 5 diagonally, and the locking hole 11
By inserting it until it matches the binding pin 5,
The binding portions 4' of the leaves 4 are kept parallel and bound together via the binding member 2 attached to the cover.

Effects of the invention: According to the invention, the required number of leaves are first assembled into the binding part attached to the cover via binding pins, and this leaf binding part is assembled with the binding part of the binding member and the end cover. It is shaped like a box depending on the side,
By inserting and loading the required number of spacers later between the leaves inside the container, strong mounting can be achieved with simple operation without having to take the trouble of fitting the spacers and leaves to the binding pins alternately. This has the advantage that the procedure is eliminated and the construction cost is reduced, and that both the upper and lower ends of the binding section are covered with cover pieces, resulting in a beautiful finish and an enhanced decorative effect.

According to the spirit of the present invention, in addition to the above-described embodiments, it is also possible to adopt a system in which two covers are combined with a binding section.
