Description

Ruler CUTTING AT AN ACUTE ANGLE FOR PROTECTING END}

An embodiment of the present invention is a design for a person capable of protecting an end surface when cutting a target at an acute angle and capable of safely and accurately cutting at a given angle.

As shown in Fig. 1(a), in the conventional product cutting method, it is common to cut so that the cross section forms an acute angle. However, if the cut surface is at an acute angle, the end surface is not sturdy and wears easily. As shown in Fig. 1(b), when manufacturing and using a plurality of cut portions in combination, the ends may be damaged or damaged because the end portions are not sturdy.

Thus, as shown in Fig. 1(c), if the end surface of the object is protected and the cut object is combined and manufactured and used, the end surface can be prevented from being damaged or damaged.

Therefore, the present invention is intended to provide a ruler that can protect the end surface of the object and cut it at a given angle safely and accurately at a sharp angle, as shown in FIG. 1(c).

An object of an embodiment of the present invention is to provide a ruler capable of protecting the end surface of an object and capable of safely and accurately cutting an acute angle at a given angle.

The body of a ruler that protects the end surface of an object according to an embodiment of the present invention for achieving the above object and can safely and accurately cut an acute angle at a given angle; A guide portion positioned at an edge of one end of the main body and formed in an inclined manner; And a jaw formed by a difference in thickness since the thickness of the guide portion adjacent to the main body is thicker than the thickness of the main body.

Preferably, both the upper surface and the lower surface of the guide part are inclined, and the angles formed by each of the upper and lower surfaces may be different from each other.

Preferably, the guide portion is located at a plurality of corners of the main body, and angles of the different guide portions with the ground may be different from each other.

Preferably, the guide portion includes a screw hole and may be separated from the main body by being coupled to the main body by using a male screw.

Preferably, the screw hole has an up and down long shape, so that the guide part may be moved up and down to adjust the height of the jaw.

Protecting the end surface according to an embodiment of the present invention and using a ruler capable of sharply cutting the object at a given angle, it is possible to protect the end surface of the object and safely and accurately cut it at a given angle.

Hereinafter, preferred embodiments according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 2 is a diagram illustrating a ruler capable of protecting an end surface and cutting an acute angle at a given angle according to an embodiment of the present invention.

Referring to FIG. 2, a ruler 100 that protects an end surface according to an embodiment of the present invention and is capable of cutting an acute angle at a given angle includes a main body 110 and a guide part 120, and a main body 110 and a guide It is characterized in that the jaw 130 by the portion 120 is formed.

The guide part 120 is located at the edge of one end of the main body 110 and is inclined with respect to the ground. That is, the guide portion 120 has a structure in which the width becomes narrower as it moves away from the main body. In general, a length scale is positioned on the guide unit 120 to measure the length, draw a line using a pen or a knife, etc., and perform operations such as cutting acute angles at a given angle.

In addition, since the thickness of the guide portion 120 adjacent to the main body 110 is thicker than the thickness of the main body 110, the jaw 130 is formed by a difference in thickness.

That is, according to FIG. 2(a), since the main body 110 has a thickness of'a' and the thickness of the adjacent guide portion 120 is'a+b', the height of the jaw 130 is'b'. When the jaw 130 is formed, as shown in FIG. 2(b), if the object 10 is placed under the ruler 100 and cut, the end surface can be protected and safely and accurately cut at a given acute angle.

As another embodiment, the object 10 may further include a non-slip part 140 on the ruler to prevent slipping on the ruler. It is preferable that the non-slip part 140 is made of a material such as rubber that can generate frictional force with the object 10.

3 is a diagram illustrating a ruler capable of bluntly cutting according to another embodiment of the present invention.

As shown in'A' of FIG. 3, the ruler 100 capable of bluntly cutting according to another embodiment of the present invention includes a main body 110 and a guide part 120, a main body 110, and a jaw 130. And, furthermore, the guide unit 120 is characterized in that both the upper and lower surfaces are inclined, and the angles each formed with the ground are different from each other.

Referring to'A' of FIG. 3, both the upper and lower surfaces of the guide unit 120 are inclined. Since the upper and lower surfaces have different inclinations, objects can be cut with different inclinations according to the user's choice (i.e., α≠β).

In another embodiment, by forming a jaw having a different height between the upper and lower surfaces, the object can be cut so that the thickness of the end surface is different according to the user's selection (ie c≠d)

In addition, as shown in'B' of FIG. 3, the guide part 120 is located at a plurality of corners of the main body, and angles formed by different guide parts with the ground may be different from each other.

That is, the angle formed by the guide portion 120 of'B' with the ground may be different from that of'α' or'β'. Furthermore, the height of the jaw 130 of the guide part 120 of'B' may be different from that of the guide part 120 of'A' (b≠c≠d≠b).

4(a) is a diagram illustrating a ruler capable of protecting an end surface and cutting an acute angle at a given angle according to another embodiment of the present invention.

The ruler 100 that protects the end surface according to another embodiment of the present invention and is capable of cutting an acute angle at a given angle includes a main body 110 and a guide part 120 and a jaw 130, but the guide part 120 Since it includes a screw hole, it can be separated from the main body 110 by being coupled using the main body 110 and the male screw 122.

Since the guide part 120 is detachable, the guide part 120 having various inclinations and various jaw heights can be separately manufactured and can be arbitrarily attached or detached according to the user's selection.

Further, as shown in Fig. 4(b), the screw hole has a long shape up and down, so the height of the jaw can be adjusted by moving the guide part 120 up and down. That is, the height of the jaw can be arbitrarily adjusted as the guide unit 120 is moved up and down.

So far, the present invention has been looked at around its preferred embodiments. Those of ordinary skill in the art to which the present invention belongs will be able to understand that the present invention may be implemented in a modified form within a range not departing from the essential characteristics of the present invention. Therefore, the disclosed embodiments should be considered from an illustrative point of view rather than a limiting point of view. The scope of the present invention is shown in the claims rather than the above description, and all differences within the scope equivalent thereto should be construed as being included in the present invention.
