Description

[Detailed description of the invention] [Industrial application field] This invention relates to a stapler for binding multiple pieces of paper, cardboard, thin plywood, etc., and more specifically, it can be used to staple ordinary books that tightly bind them together. The present invention relates to a stapler that can selectively perform binding and temporary binding for temporarily fixing slips, memos, etc. to mounts, cardboard, etc.

[Conventional technology]

Staplers are widely used when bundling multiple sheets of paper into a single stack, or when securing notes or slips with information on items to be stored, shipping addresses, etc., to paper boxes or cardboard boxes. The stapler used in such a stapler is a wire-shaped needle that has a support part and a pair of parallel binding feet bent approximately perpendicularly from both ends of the support part, taking into consideration the ability to penetrate the objects to be stapled. It is composed of linear bodies. On the other hand, a stapler includes a bending table member in which a bending groove is formed for bending the binding foot of the stapler, and a stapler support that houses the stapler and has a staple ejection port opening in a portion opposite to the bending groove. It is mainly composed of three members: a member and a pressing lever member that presses the staple toward the staple ejecting port at a portion behind the staple ejecting port.

When binding, bundle multiple sheets of paper to be bound, insert them between the bending table of the base member and the staple support member, position the part to be bound on the bending table, and press the pressing lever member toward the base member. do. As a result, the binding needle sticks into the paper from the punching opening, and both ends of the binding foot portion of the binding needle penetrate the paper and come into contact with the groove bottom of the bending groove of the bending table. Then, in response to the pressing force of the pressing lever member, each tip of the binding foot bends along the shape of the groove bottom of the bending groove, bends approximately 90 degrees, and presses against the back surface of the bottom sheet. Therefore, the top paper is crimped to the support of the staple, and the bent binding foot is crimped to the back of the bottom paper, making it possible to form a stack of the desired number of sheets. .

In this way, staples can easily bind multiple sheets of paper together, so they can be used not only for permanent binding, but also for temporary binding and eventually binding other sheets together. It's being used. In such cases, the temporary staple must be removed and, in the case of thick stacks, a thin piece of metal may be inserted between the top sheet and the staple support to pull the support up. If you do this, you can open the binding foot and remove the staple, but if the paper is thin, the metal piece will tear not only the topmost paper but also the paper below it. there is a possibility. Furthermore, there is a possibility that the hole through which the binding foot passes will expand as the support is pulled up. Therefore, in order to carefully remove the staple, it is necessary to return the curved binding foot to a straight line and then carefully pull it out from the support section.

On the other hand, when packaging a product, etc., when temporarily securing a memo or slip indicating the contents of the box, the address, etc., the memo is temporarily secured to the box using mending tape or the like. However, if the box is made of cardboard or if the memo or slip is to be used later, there is a possibility that the top paper of the memo or cardboard may be torn when the mending tape is removed.

Therefore, in Utility Model Application No. 1-150206, the present applicant proposed a binding needle for temporary binding in which only one end of the supporting part is bent approximately vertically to form one binding foot. , also proposed a stapler for temporarily binding documents, etc. using this binding needle for temporary binding in Utility Model Application No. 52476/1983 (Kokai No. 156876/1998).

[The problem that the idea aims to solve]

However, if permanent binding is to be performed during temporary binding, replacing the stapler each time reduces work efficiency.

Therefore, the purpose of this invention is to integrally configure a normal binding needle and a binding needle for temporary binding as described above,
To provide a stapler capable of selectively performing permanent binding and temporary binding.

[Means to solve the problem]

The stapler of this invention includes a support part, a stapler for book binding having two binding feet bent at a substantially right angle from both ends of the support part, a support part, and a stapler for book binding having two binding feet bent at a substantially right angle from one end of the support part. A stapler that can selectively use binding staples for temporary binding each having one bent binding foot, the upper surface of which is approximately rectangular, and the edges of both longitudinal sides thereof extending downward. A handle portion with a side wall formed thereon is swingably positioned between the side wall, and both ends of the handle portion in the longitudinal direction are slidably inserted into the open case cover from both ends of the case cover. First and second stapler cases each having a gap corresponding to the thickness of the stapler at the protruding end and which elastically presses the stapler in the direction of the gap, and a handle portion and a case cover are provided with a pivotable structure between the handle portion and the case cover. The first and second staple pressing parts each have a tip that is attached to the first staple case and descends through each gap of the first and second staple cases, and a substantially central part of the case cover and the central part thereof pivot. The base part has guide grooves on both ends of the upper surface for bending the binding foot of the binding staple, and the base part is interposed between this base part and the case cover part, and each gap and each guide groove an elastic member that elastically presses the first binding needle to open the space between the two; It includes a holding stand and a cover part that slidably holds the main body. It is characterized by spaced apart side parts, one longitudinal end extending substantially horizontally from the upper end of the side part, and the other longitudinal end abutting the other side wall of the main body. .

[Effect]

As mentioned above, the staple for permanent binding is housed at one end, and the staple for temporary binding is housed at the other end, so place documents etc. on the base on the side of the staple to be used, and then press the handle on that side. Documents can be permanently bound or temporarily bound with the simple operation of pushing down on the paper. Replenishment of staples can be carried out simply by holding the handle horizontally and pulling out the desired first or second staple case.
Furthermore, although two types of staples are accommodated, the first and second staple cases and the first and second staple pressing parts are configured independently, but these parts are shared by both. Because of this structure, it is possible to reduce the number of parts and simplify the assembly process, and it can be provided at low cost.

As described above, the stapler of this invention includes a support part, a binding needle for book binding having two binding feet bent at substantially right angles from both ends of the support part, a support part, and A tape stapler that can selectively use binding staples for temporary binding each having one binding leg bent at a substantially right angle from one end, the upper surface of which is approximately rectangular, and the edges on both sides in the longitudinal direction. A handle portion is formed with a side wall extending downward, and the handle portion is swingably positioned between the side wall, and both longitudinal ends of the handle portion are slidably inserted into the open case cover from both ends of the case cover. First and second stapler cases that elastically press the stapler in the direction of the gap have a gap corresponding to the thickness of the stapler at the ends protruding from both ends of the case cover, and a space between the handle part and the case cover. first and second staple pressing parts each having a tip portion that is pivotably attached to the case cover and descending through each gap of the first and second staple cases; The central part is pivotally attached, and the base part is provided with a guide groove on both ends of the upper surface for bending the binding foot of the binding needle, and is interposed between the base part and the case cover part,
an elastic member that elastically presses each gap and each guide groove so as to open the gap between each gap and each guide groove;
This main body includes a staple holding stand installed inside the main body, and a cover part that slidably holds the main body. and a side portion positioned at a sufficient interval for the binding foot to pass through, one longitudinal end extending approximately horizontally from the upper end of this side portion, and the other longitudinal end abutting against the other side wall of the main body. It is something that As a result, the staple for permanent binding is housed at one end, and the staple for temporary binding is housed at the other end, so place documents, etc. on the base on the side of the staple to be used, and press down on the handle on that side. With this simple operation, documents can be permanently bound or temporarily bound.
Replenishment of staples can be carried out simply by holding the handle horizontally and pulling out the desired first or second staple case. Furthermore, although two types of staples are accommodated, the first and second staple cases and the first and second staple pressing parts are configured independently, but the parts in the example are shared by both. With this structure, it is possible to reduce the number of parts and simplify the assembly process, and it can be provided at low cost.
