Description

[Detailed Description of the Invention] The present invention is applicable to commonly used paper binding.
It can also be used for driving staples when attaching decorative wall panels from ceiling panels with adhesive, and for fixing display items such as clothes to walls in shops. This invention relates to a stapler that can be used for multiple purposes, such as as a substitute for staplers.

When attaching a ceiling board or decorative plywood to a ceiling or wall, apply adhesive to the base material, apply the decorative plywood to this, and secure it by driving a number of nails for temporary fixing. However, when the adhesive hardens and the bonding is completed, many temporary nails are removed. In addition, in department stores and the like, clothing is often pasted on the walls, and this is done by manually driving in a large number of small needles one by one. All of these tasks are not easy as they involve holding the nail or needle in one hand and driving it in with the other hand many times. It would also be extremely convenient if the push pins could also be supplied continuously with a stapler. On the other hand, staplers, which are popular for office use, are convenient for binding multiple sheets of paper, cloth, sheets, etc. However, it has almost no other functions other than the function of combining a large number of sheets of paper. As a result of various studies, the present inventor focused on the large number of staples that a stapler has and the fact that they can be easily driven in succession.
It slides on the staple ejection surface side of the staple holding member of the stapler from the staple ejection part to the position near the pin, has a predetermined wall thickness, and has an ejection port in the part facing the staple ejection port. A sliding piece having a protruding staple bent part 15 is provided to cover the staple bending part 15, and a staple holding block on which a staple can be placed is mounted inside the staple holding member, and the staple holding block has a longitudinal direction. A hollow portion is provided in the direction of the staple holding block, and the hollow portion is connected to the front and back surfaces of the staple holding block by a split groove portion, and the columnar pressing portion at the center of the staple pressing member having a square cross section is fitted into the hollow portion of the staple holding block, and a spring is applied to the staple holding block. A removable spacer having a substantially square cross section is provided on the staple ejection port side of the staple holding member. With this structure, it has a multi-purpose function that can be used for temporary fixing of decorative plywood, etc., display pasting, and general office use as push pins and paper binding. It is.

This will be explained in detail below with reference to the drawings.

FIG. 1 is a central vertical sectional view of a stapler according to an embodiment of the present invention. Figure 2 shows A in Figure 1.
- An enlarged sectional view of part A is shown. In this stapler, a base plate 2, a staple holding member 3, and a staple ejecting member 4 are rotatably integrated by a pin 1 as in the conventional stapler. The base plate 2 is in a state where the staple holding members 3 are opened by a plate spring 5 provided near the pin 1, and the staple pushing member 4 is
A spring part 7 is elastically supported by a spring receiving plate 6 which is also rotatably attached to the pin 1. When staples are fastened by grip force, the base plate 2 and the staple ejection ports 8 of the staple holding member 3 move closer together against these springs, and a large number of staple ejecting plates 9 of the staple ejecting member 4 are connected. The staple at the tip of the staple 10 is pushed out one by one. Such a mechanism is similar to the conventional one.

The structure of the staple holding member 3 portion is the most distinctive feature of the present invention. FIG. 3 shows an exploded perspective view of this part. Elongated holes 11, 11 are provided on both sides of the staple holding member 3, and the elongated holes 1
1 is partially provided with protrusions 12. The sliding piece 13 is attached to the lower surface of the staple holding member 3 using the elongated holes 11, 11. The sliding piece 13 has a predetermined thickness as described later, has a square cross-section, has protrusions 14 for attachment to the elongated hole 11 on both sides, and has a tip that covers approximately half of the staple ejection port 8. The staple bent portion 15 is formed by providing a shape and a depression in this portion. When the sliding piece 13 having such a structure is attached to the staple holding member 3, the sliding piece 13 slides arbitrarily from the staple ejection opening 8 to a position near the pin 1, and the protrusion 12
It can also be kept in place by How to use this sliding piece will be explained in detail later.

Conventionally, staples were stored inside the staple holding member 3, and the staples were sequentially moved to the staple ejection opening 8 by a staple pressing member, but in the present invention, the staples are stored in the staple holding member 3, and the staples are sequentially moved to the staple ejection opening 8 by the staple pressing member. It has a special structure that can hold many types of staples. That is, as seen in the upper part of FIG. 3, the staple holding block 16 fitted into the staple holding member 3 has never been seen before. This staple holding block 16 may be fixed coaxially with the pin 1 like the other parts, or it may be fixed to the inner bottom surface of the staple holding member 3. A cavity 17 is provided inside the staple holding block 16, and this cavity 17 is connected to the front and back surfaces of the staple holding block by a groove 18. Therefore, it is possible to hold not only normal type staples shown in b and c in FIG. 4, but also a T-shaped staple having only one needle in the center as shown in a. For this staple holding block 16, a staple pressing member 19 having a square cross section
is attached. The staple pressing member 19 is the second
As can be seen in the figure, a columnar spring receiving part 20 is provided at the center, which is fitted into the hollow part 17, and is elastically supported by a spring 21 fitted into the hollow cylinder part 17. In the case of a staple having two needle parts, not only the upper part of the staple but also both needle parts are pressed to send the staple to the injection port 8 side. Also, 1
Even in the case of a staple having a book needle, one of the columnar spring receivers 20 presses the needle and feeds it stably to the injection port 8.

Unlike conventional staplers, the staple ejection opening 8 at the tip of the staple holding member 3 is designed to be wide so that staples of different widths can be used. Therefore, when using regular width staples, the cross section shown in Figure 3 is
A shaped spacer 22 is attached to the staple exit side as shown in FIG. When driving a wide staple 10 as shown in FIG. 4a,
This spacer 22 is removed to widen the staple ejection port 8 for use.

The stapler of the present invention is used as follows.

First, when using it in the same way as a normal stapler, such as paper binding, move the sliding piece 13 of the staple holding member 3 toward the pin 1 side as shown by the solid line in FIG. It is used by attaching it to the front plate of. In this state, the sliding piece 13
can be used in the same way as a normal stapler without contacting the base plate 2 to be pressed. Next, in order to use it for fixing clothes, etc. to a wall surface for display purposes, a longer staple as shown in FIG. and bring it in front of the staple exit port 8,
The base plate 2 is rotated as shown by the two-dot chain line in FIG. 1, and the staples 10 are driven from above the garment as shown in FIG. 5b. Clothes 24 can be placed on a wall surface 23 while retaining the feel of the clothes. The distance between the wall surface 23 and the upper striking portion of the staple 10 is regulated by the thickness of the sliding piece 13. Since the staples driven in this way protrude from the wall surface, they can be easily removed.

As shown in FIG. 5a, when attaching the decorative plywood 26 to the base material 25 using adhesive, staples 10 are used for temporary fixing until the adhesive layer 27 is completely solidified. To drive in, slide piece 13
was moved to near the tip of the staple holding member 3 to cover one side of the staple ejection port 8 with the staple bent portion 15, and the base plate 2 was removed from the staple ejection port 8 by rotating in the same manner as in the previous case. state. When the staple extrusion member 4 is hit by hand or with a mallet in this state, one needle portion of the staple 10 is bent at the bent portion 15 of the sliding piece 13, and only the other needle portion is bent from the top of the decorative plywood 26 to the base plate. The material is driven up to 25. Therefore, temporary fixing can be done, and
Since the staple has a bent portion, it is easy to remove the staple after adhesion is completed.

What is shown in FIG. 4a is a T-shaped staple with a single needle portion that can be used in place of a push pin. The ability to drive the push pin type staple 10 is also possible, which has not been seen in conventional staplers. Moreover, since it has a simpler structure than conventional push pins, it can be used at low cost, and the present invention enables mechanical hammering, resulting in the effect of improving efficiency.

Since the present invention has the structure as detailed above,
By moving the sliding piece in the longitudinal direction of the staple holding member, if the sliding piece is positioned on the pin side, it can be used as a regular stapler, and if it is positioned in front of the staple injection part, it can be used for display purposes. By making it possible to insert two staples and setting the staple in a position that covers only one side of the staple injection part, only one side of the staple can be used for temporary fixing of decorative plywood. Furthermore, by attaching and detaching the spacer, both thick and thin staples can be driven. The present invention is also significant in that it allows the stapler to be used in many different ways, such as the ability to use either one staple or two staples.

Staples driven by the stapler of the present invention, both temporary staples and display staples, are easy to pick up and therefore easy to remove. Furthermore, since the staples driven by the stapler can be threaded with thread to hang the product in space, various decorations are possible. Furthermore, this stapler can be used in a shorter time and with less effort than conventional methods, making it a great contribution to streamlining these operations.
