JPS5920208Y2 - Cutter for cutting off protruding parts of laminated sheet materials - Google Patents

Description

[Detailed description of the invention] This invention relates to a cutter for cutting off protruding parts of sheet materials attached to fittings, furniture, etc.

Recently, it has become popular to attach sheet materials made of paper, synthetic resin, etc. printed with various patterns such as wood grain to the surfaces of fittings, furniture, etc.

By the way, when pasting sheet materials on the surfaces of fittings, furniture, etc.
After pasting the sheet material so that it slightly overhangs the corners of fittings, furniture, etc., the overhanging portion is cut off using a knife, scissors, plane, etc.

However, with this method, it is not possible to cut the edges of the sheet material straight, so it is not possible to achieve a clean finish.

Moreover, the work is time-consuming, labor-intensive, and laborious.

The purpose of this invention is to provide a convenient cutter that allows anyone to easily, quickly and neatly cut off the protruding portion.

This device is an improvement on a device related to a utility model patent already obtained by the applicant of this application (see Utility Model Registration No. 1498877, Publication of Utility Model No. 57-56814).

Next, embodiments of this invention will be described with reference to the drawings.

FIG. 1 is an exploded perspective view showing the first embodiment of this invention, and 1 indicates the main body.

The main body 1 has a substantially rectangular shape, and the front half of the main body 1 is made up of two symmetrical guide bodies 2, which are arranged oppositely with a slight gap 3 between them.

The inner surfaces of each of the guide bodies 2, 2 are formed to be inclined in an inverted V shape to form a guide surface 4°4.

As is clear from FIG. 3, which is a perspective view seen from below,
The guide surfaces 4, 4 extend to the rear end of the lower surface of the main body 1.

That is, the guide surface 4.4 from the front end to the rear end of the lower surface of the main body 1 is formed in an inverted V shape.

A dovetail groove is formed in the front end of the rear half of the main body 1 in the lateral direction, that is, in the direction orthogonal to the gap 3, and serves as a knife guide groove 5.

Note that the blade guide groove 5 is provided so as to be inclined slightly downward with respect to the front.

A cutter 6 whose tip is a knife blade is inserted from the side into this cutter guide groove 5, and the cutter 6 can be slid within the cutter guide groove 5.

Two female screw holes 7, 7 are provided at the rear of the blade guide groove 5.

A separate plate-shaped presser member 8 is prepared, and the presser member 8 is also provided with two holes 9.

After inserting the cutter 6 into the cutter guide groove 5, place the holding member 8 on top of the cutter 6, and insert screws 10 and 10 into the holes 9 and 9, respectively.
When the blade 6 is firmly supported by the presser member 8 by screwing it through and into the female holes 7, 7, the blade shown in FIG. 2 is completed.

The thing shown in Fig. 2 looks like Fig. 3 when viewed from below.

To use what has been explained above, do as shown in FIGS. 4 and 5.

The sheet material is attached to a wide area so that it slightly protrudes from the corners of fittings, furniture, etc., so the protruding part is attached to the guide body 2.
, 2, firmly press the tips of the guide surfaces 4, 4 against the tips of the corners of fittings, furniture, etc. (Fig. 4).

When the guide surfaces 4, 4 are guided by the corners and moved forward, the knife 6, which is firmly held in the knife guide groove 5, neatly cuts the protruding part of the sheet material along the corners of fittings, furniture, etc. (Figure 5).

In addition, when the sharpness of the knife 6 has deteriorated, the knife 6 is slid a little along the knife guide groove 5, and a new blade is brought out before cutting.

Recently, synthetic resin type sheet materials with adhesive applied to the back side have been increasingly used, but in the case of such sheet materials, the synthetic resin or adhesive gets entangled with the knife 6 and it becomes difficult to cut in one go.゛, Slide the knife 6 each time.

In this way, the entire blade portion of the knife 6 can be used while sliding.

In addition, the blade 6 is supported slightly downward, and is also supported by being fitted into the dovetailed blade guide groove 5, so the blade 6 is unlikely to wobble when cutting the sheet material. For further safety, the blade 6 is held down completely by a holding member 8.

Next, a second embodiment of this invention will be explained with reference to FIG.

In the first embodiment, since the cutter 6 is supported at an angle to the corner of the fittings, furniture, etc., the edge of the sheet material is also cut at an angle to the corner.

If you want to cut the sheet material parallel to one of the surfaces of fittings, furniture, etc., one method is to use the second embodiment.

That is, a rising portion 11 is formed in one half of the rear half of the main body 1, and an inclined surface 12 is formed in the rising portion 11 from the center.

When the blade guide groove 5 is formed on the inclined surface 12, the blade 6 is supported parallel to one guide surface 4 of the guide body 2.

Although two embodiments of this invention have been shown above, the embodiments of this invention are not limited to the above embodiments.

For example, although the cutter force guide groove 5 is formed by cutting the main body 1 itself, a separate member may be attached.

If the blade guide groove 5 is made accurately, the holding member 8 is not necessary.

When using the presser member 8, it may be used in two pieces.

Alternatively, it may be used from the front instead of from the rear.

When using it from the front, it is best to use it in two places, on the left and right across the center.

It is convenient to make the guide body 2 removable from the main body 1 so that it can be attached only when necessary.

Possible means for making it detachable include attaching it with screws or bolts, or using dowels or magnets.

The structure of this invention is as described above, and this invention produces the following excellent effects.

To use the cutter according to this invention, the inverted V-shaped guide surfaces 4, 4 provided on the lower surface of the main body 1 are placed against the corners of fittings, furniture, etc., and the cutter is moved along the corners.

Since the guide surfaces 4, 4 guide the main body 1, it moves straight and cuts the protruding part of the sheet material attached to the surface of fittings, furniture, etc.

The work requires almost no effort, can be completed in a short time, and the finished product is extremely good.

If the blade 6 loses its sharpness, you can continue cutting by sliding it little by little each time to expose a new blade.

When all the blade parts are used up in this way, a new blade 6
You can replace it with

Since the two guide bodies 2, 2 are provided in front of the main body 1 with a gap 3 formed between them, as shown in FIG. The tip of 2, 2 can be applied to the tip of fittings, furniture, etc., and the cutter can be cut while being guided by the guide surfaces 4, 4, so after cutting off the protruding part of the tip with scissors etc. It is convenient because there is no need to hit and cut.

If the guide bodies 2, 2 are made detachable, the guide bodies 2,
2 can be removed if it is not needed or if the guide body 2.2 gets in the way.

When cutting to the corner, the guide bodies 2, 2 may get in the way.

In particular, the cutter related to this invention was manufactured by a joiner who was a major joinery manufacturer (
Refers to both sides of the fittings.

) is ideal for cutting off the protruding part of the tape after pasting it on the tape.
