Description

[Detailed Description of the Invention] The present invention is a stapler that has made it possible to significantly expand the scope of use of conventionally used mechanical staples not only in the construction sector, but also in interior decoration, electrical work, etc. Regarding.

A staple having two driving needles can be mechanically driven with a tacker by having a connected structure, and is mainly used for lathing, ceiling material driving, sheeting, etc. In the conventional method of using staples, in most cases, two staples are driven in both of them, and in most cases, the staples are driven completely to the base.

On the other hand, in the construction field, when adhering decorative plywood or ceiling panels to walls or ceilings using adhesive, the decorative plywood coated with adhesive is temporarily secured using a large number of temporary nails, and the adhesive is applied to the decorative plywood. A so-called temporary fixing method is used in which the temporary fixing nails are removed after the adhesive has solidified and the adhesion is completed. In this temporary fixing method,
The present inventor has studied various ways to use staples that can be machined in place of temporary nails. We then considered the need for two functions: sufficient pressure for temporary fixing, and ease of removal after adhesion. This made it possible to use staples in the temporary fixing method by driving only one of the needles that remained after the bend, or by driving both needles halfway.

For this purpose, we have developed a new tack car with the structure shown below and have come to propose it here. That is, in a stapler that drives a held hammer plate by a hammer drive lever and drives the connected staples from the staple ejection part while cutting them off, the staple ejection part has a one-sided shielding part that covers only one staple of the staple. The present invention is characterized in that a caul plate having a padding plate is removably attached thereto, and a recess for staple bending is provided in the shielding portion on one side of the caul plate. With this structure, the staple injection section of the stapler can attach and detach the caul plate, and
Alternatively, by moving the mounting position back and forth, the entire surface is opened like in the conventional usage example, but one needle is shielded by a caul plate, or the staple injection part and the plate to be driven are It became possible to take three different configurations in which gaps could be provided between the two by means of a backing plate. Therefore, the tatsuker of the present invention can be used not only for pasting lath and fixing between timbers as in the past, but also for temporary fixing methods, making it possible to have a wide range of uses in the construction field. Its use has expanded to an extremely wide range, including display applications for fixing clothing and the like to walls, and mechanical staples for wiring electrical wires.

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

FIG. 1a is a side view of the first embodiment of the present invention, and FIG. 1b is a perspective view of the caul plate 1. FIG. Figure 2 is the second
FIG. 3 is a perspective view of a patch plate according to an embodiment. FIG. 3 is a perspective view of a tucker according to a third embodiment, and FIG. 4 is a perspective view of essential parts of a tackler according to a fourth embodiment. Figure 5 a~
d is a front view showing the staple driving state;
FIGS. 6a to 6d are longitudinal cross-sectional views showing examples of the shapes of the hammer plate and the caul plate.

In the present invention, the tacker main body drives the hammer plate 2, which is supported by a spring, with the hammer drive lever 3, and drives the staple into wood etc. from the staple injection part 5 while cutting off the connected staple 4. This allows the conventional tatsuker structure to be used as is.

The most distinctive feature of the present invention is the patch plate 1.
As mentioned above, the backing plate serves to cover only one staple of the staples ejected from the staple ejection section 5, or to provide a gap between the staple ejection section 5 and the material to be driven, such as wood or decorative plywood. be. The one shown in FIG. 1 as an example of the shape of the backing plate 1 has a groove-shaped cross section with a length that spans almost the entire length of the tacker body, and one end covers only one side of the staple injection part 5 of the tacker. A one-sided shielding portion 6 is formed to protrude. The one-sided shielding part 6 is provided with a recess 7 for bending one needle of the staple. The other end of the backing plate 1 has raised edges 8, 8 on both sides for attachment to the tack body, and mounting holes 9 are provided in the raised edges 8, 8. As shown in the figure, the mounting hole 9 is provided with positioning notches 10A and 10B, and as shown in FIG.
When one positioning notch 10B is fitted into 1,
The one-sided shielding part 6 at the other end of the backing plate 1 is in a state of covering one side of the staple injection part 5 of the stapler body. When the hammer drive lever 3 is strongly squeezed in this state, the staple 4 is ejected, and one of the staples is bent by the recess in the one-sided shielding part 6 of the caul plate 1.
The other needle is directly driven into decorative plywood or the like. The situation is as seen in FIGS. 5a to 5c. When the tassel main body assembly pin 11 is fitted into the other positioning notch 10A of the caul plate 1, the staple injection part 5 is not shielded at all, but when the staple is ejected, the caul plate is attached to the tassel and the decorative plywood. A gap is created between the tacker and the object to be driven. When the hammer drive lever 3 is operated in this state, the staple 4 is ejected by the hammer plate, but the backing plate 1
It will not be driven in by the thickness of , and will stop midway.
FIG. 5d shows the state of the staples driven in this manner. A leaf spring 12 is attached to this backing plate 1, so when the tacker is pressed against the object to be driven, the backing plate approaches the staple injection part as shown by the two-dot chain line.

FIG. 2 shows a patch plate 1 in a second embodiment. This caul plate 1 is of a type that is used by fitting both lip portions 13, 13 of the caul plate 1 into the caul plate sliding grooves provided on both side walls of the staple holder of the stapler body. By sliding it in the longitudinal direction,
The single-sided shielding part 6 at the tip covers and releases the staple injection part 5.

In the example shown in FIG. 3, the cover plate 1 is rotatably attached to a rotary shaft 15 whose both ends are fixed to the side wall of a staple holder 14 of a stapler. When using it as a regular tatcher, rotate the backing plate 1 to remove it from the staple injection part 5 side as shown by the solid line in the figure, and when using it for temporary fixing of decorative plywood, etc. Then, set the one-sided shielding part 6 so that it is located on the staple injection part side.
Furthermore, by moving the rotary shaft 15 in the longitudinal direction, it is also possible to drive a double staple as shown in FIG. 5d.

The example shown in Figure 4 is the same as the one in Figure 1 and the patch plate 1.
is similar, but it is designed so that it can be attached to the stapler main body assembly pin 16 near the staple injection part 5, and the method of use when driving staples is the same as the one in Fig. 1, but the backing plate 1 When it is not needed, it can be attached to the hammer chamber 17 side of the tack car body, so it does not get in the way and is convenient.

As exemplified above, the tacker of the present invention can be put to practical use in many structures. All of these allow various types of driving as shown in FIGS. 5a to 5d, and since the caul plate can be easily removed, it is also possible to use the same conventional method of driving both staples.

5a to 5c show how staples are driven from above the decorative plywood 18 using the tacker of the present invention when adhesive 19 is applied to the decorative plywood 18 and the adhesive 19 is applied to the base material 20. This type of staple driving work involves a large number of staples, but since it has become possible to do so with a stapler, labor savings have been achieved. After adhesion is completed, the staple can be easily removed by pinching the bent portion or by hooking it with a hook. Of course, it is also excellent in that it leaves almost no noticeable holes after it is removed. In order to pull out the staples, it is also possible to provide pull-out claws, such as those found in conventional staplers, at the corners of the stapler body.

According to the stapler of the present invention, one needle of the staple can be bent into various shapes. In order to form a long bent ring as shown in FIG. 5a, a long curved recess 7 is provided in the one-sided shielding part 6 of the backing plate 1, as shown in FIG. 6a.
Furthermore, it is preferable to provide the hammer plate 2 with a chevron-shaped notch.
In order to bend one of the staples and overlap them from the base as shown in Figure 5b, see Figure 6b.
As shown in FIG. 1, a shallow flat recess may be provided in the shielding portion 6 on one side of the caul plate, and the hammer plate 2 may have a flat tip as in the conventional case. In order to bend one of the staples into a small-diameter annular shape as shown in FIG. 5c, a small-diameter, deeply curved recess is provided in the shielding portion 6 on one side of the caul plate, as shown in FIG. 6c. Furthermore, it is preferable to cut out the hammer plate 2 into a rectangular shape. In this way, one needle of the staple can be bent into any shape depending on the shape of the hammer plate 2 and the shape of the one-sided shielding part 6 provided on the caul plate.

The method shown in FIG. 5d is different from the conventional method of driving staples. This means that when displaying new designed clothing 22 on a wall 21 to show it to customers in a store, etc., the product of the present invention can be used to
This is an example in which 2 is fixed with a staple driven halfway. Previously, a large number of needles were manually hammered into the wall surface from above the clothing, but the completion of this invention has attracted attention as it has become possible to create a display by machine hammering while maintaining the soft feel of the cloth. This is a worthy use case. In order to drive staples in this way, the caul plate 1 is moved and as shown in FIG. With a patch plate between the main body and the wall,
Place the staple ejection part 5 on the garment and pull the hammer drive lever.

The method of typing in Figure 5 d also applies to electric wires, telephone wires,
It can also be used as a substitute for U-shaped nails for fixing ground wires, etc. to construction materials, and the work can be done quickly if you apply a piece of thick insulating tape while driving the nail.

The present invention has a structure as described in detail below, and has achieved great effects such as expanding the field of use of the tucker and greatly contributing to labor saving.
