Abstract

The present invention relates to a punch blade of a punch used for punching paper, textiles, fibers, metals, and various materials, which often occurs when the material punched by the punch does not fall on the punch blade. The pressing portion, which is the center portion of the punching blade, protrudes convexly in a streamline shape, and functions to press the material or the like into the pressing portion to be separated from the punching blade.

Description

Punch blade of punch {A BLADE OF THE PUNCH}

The present invention relates to a punch blade of a punch used for punching paper, textiles, fibers, metals, and various materials, and more particularly, the material punched by the punch does not often fall on the punch blade. In order to prevent this, the pressing portion, which is the center portion of the punch blade, protrudes convexly in a streamline shape, and relates to a punch blade of a punch having a function of pressing the material or the like with a punch to separate it from the punch blade.

The punch blade of the punch can be understood by understanding the structure of the stationery punch. In general, the stationery punch is designed to easily punch a single sheet of paper or a small thickness of paper. It is well disclosed in Korean Registered Utility Model Publication No. 20-0191105.

Looking at the general structure of the punch disclosed in the publication, as can be seen through Figure 3, the guide frame is fixedly installed on the upper portion of the base member, an insertion space such as paper and paper is provided between the base member and the guide frame The upper side of the guide frame is provided with a pressing member rotatably coupled to one side by a hinge. In addition, the guide frame is installed in the longitudinal direction so that the punching rod can be raised and lowered, the punching rod is integrally coupled to the pressing rod supported in the transverse direction to the pressing member is installed and supported, the pressing member and the guide frame is always unfolded by a spring Is burnt in the direction.

According to such a structure, if paper and paper are inserted into the space between the base member and the guide frame, and then the pressing member is pressed, the pressing rod interlocking with the pressing member is lowered along the lifting guide hole of the guide frame. As a result, the punching rod, which is integrally coupled to the pressing rod, passes through the punching holes of the guide frame and the base member and descends to punch holes in paper and documents.

After releasing the pressing force by releasing the hand from the pressing member, the pressing member is raised by the elastic restoring force of the spring, and the pressing rod and the punching rod interlocked with it are restored to the initial setting position, and then prepare for the next downward punching operation. Will be done.

However, in the punch blade of the conventional punch as described above, the punched paper is often stuck without falling off the punch blade, as shown in Figures 2 and 3, the punched paper is bent in the middle portion Both ends of the paper will span both sides of the punching edge and will not fall off.

In particular, when a plurality of papers are punched by punch blades of a conventional stationery punch, a plurality of papers are integrated as a single paper due to the pressure transmitted through the pressing member, and a plurality of thickened papers are much more on the punch blades. It is better draped and will not fall off the punch blade.

The paper not removed from the punch blades causes a problem of lowering the efficiency of the next punching operation.

In addition, the paper that does not fall from the punching blade is scattered sporadically on desks or offices, causing a problem of messy clean office space.

Therefore, the present invention is to overcome the above-mentioned conventional problems, the object of the present invention is that the perforated paper, fabric, fiber, metal, various materials do not span the punch blade, when the user applies a single pressure to the punch Not only is the material perforated every time, but also to provide a structure in which the perforated material is separated from the punch blade under pressure from the pressing portion.

In order to achieve the above object, the punch blade of the punch according to the present invention has a structure in which the pressing portion protrudes in a streamlined convex shape in the center portion to press paper, fabric, fiber, metal, various materials, etc. with a punch to separate it from the punch blade. It is characterized by providing.

In addition, the shape of the pressing portion, as shown in Figure 5, the center portion of the punch blade protruding convexly, the center portion sharply protruding, and the center of the punch blade and the convex structure protruding circularly It can have the same embodiment.

Although the present invention has been described above with reference to the drawings and specific embodiments, the present invention is not limited to such a specific structure. Those skilled in the art may variously modify or change the present invention without departing from the spirit and scope of the present invention as set forth in the claims below. Nevertheless, all such modifications or variations are intended to be clearly understood as falling within the scope of the present invention.

According to the present invention made up of the above-described problem solving means, the pressing portion, which is the center portion of the punch blade, protrudes convexly in a streamline shape, and presses the paper, fabric, fiber, metal, and various materials with the punch to separate it from the punch blade, and punches work. It increases the efficiency of the paper and collects the paper falling by the punch into the storage space inside the punch without sporadically falling onto the desk or office space.

Hereinafter, the present invention will be described with reference to the state diagram of use and the accompanying drawings as follows.

1 is a punch blade of the punch according to the present invention is shown for explaining a cross-sectional perspective view.

As shown in FIG. 1, the pressing portion 3 protrudes convexly and convexly in the center portion of the punch blade 2.

Fig. 2 is a perspective view of the paper which has been punched out by a punch, and is a perspective view. The flat sheet of paper 21, the flat sheet of paper 22, and the folded sheet of paper folded by the conventional punch are punched by the present invention. (23). There are several sheets of paper 24 that are bent.

3 is a diagram showing a state of use in which the concave punch blade 12 of the conventional punch 5 is provided, and has a structure in which the central portion 13, which is the center portion of the concave punch blade 12, is recessed, and also concave. It can be seen that one sheet of paper 23 bent between the punch blades 12 or several sheets of paper 24 bent together without falling off.

Figure 4 is a state diagram showing the use of the punch blade 2 of the present invention punch 6, the pressing portion (3) in the center convex protruding convex streamlined flat sheet of paper (21) or several flat It can be seen that the sheet of paper 22 is pressed and separated from the punch blade 2.

Figure 5 shows another embodiment of the present invention, the streamlined pressing portion (3a, 3c, 3d) that is the center portion of the punch blade convex protruding in a streamline, the sharp pressing portion 3e that the center portion protrudes sharply ) And a circular pressing portion 3b protruding convexly in the center of the punch blade.

Although the present invention has been described above with reference to the drawings and specific embodiments, the present invention is not limited to such a specific structure. Those skilled in the art may variously modify or change the present invention without departing from the spirit and scope of the present invention as set forth in the claims below. Nevertheless, it will be apparent that all such modifications or variations will fall within the scope of the present invention.

1 is a cross-sectional perspective view showing a punch blade of a punch according to the present invention;

2 is a perspective view showing a sheet of paper punched out by a punch;

3 is a state of use of the existing punch;

Figure 4 is a state of use of the punch blade of the punch according to the present invention;
