JPH08882U - Grooved nails - Google Patents

Abstract

(57) [Summary] [Purpose] To reduce the bending of nails. [Structure] The nail has several grooves and the head is a flat or round cross head. Because the blade formed by the groove cuts into the material to be driven and because the volume is smaller than that of conventional nails, when fixing each material together, bending of the nails is reduced and it is possible to drive easily.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention has a cross-shaped structure.When it is hammered in, the material is driven by the blade made by the groove rather than the round nail, so that the material is driven straight and the volume of the material to be driven is small. Because it is small, it does not bend and is easy to drive, and in the case of wood there is no crack in the wood.

[0002]

[Prior art]

 As shown in the figure, the conventional round nail has a round iron core structure as is well known, and since it has a large volume, it easily bends.

[0003]

[Problems to be solved by the device]

 Since the round nails currently on the market have a round iron core structure, they are weak against the force of hammering in, especially from the side or the side, and are easily bent. The purpose of the present invention is to eliminate the above-mentioned drawbacks and reduce the bending of the nail main body so that the nail can be driven straight.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention has a smaller volume than a round nail by providing several grooves in the main body of the nail, and it also bends because it cuts into each material driven by the blade made by the groove. It is reduced and can be easily driven.

[0005]

[Action]

 By making a few grooves in the nail body, the blade made by the groove cuts into the material to be driven, so there is less bending, and since it has a smaller volume than a round nail, it can be easily driven.

Further, since the area of the grooved nail is larger than that of the round nail in a state where the nail is driven into the material and fixed, it is hard to come off and is firmly fixed.

[0007]

【Example】

 Examples will be described with reference to the drawings. In FIGS. 1 and 2, the grooved nail has a cross section that is not circular but has several grooves to reduce the volume thereof. As a result, it is easy to drive each substance and the bending frequency is reduced.

[0008]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects. In the grooved nail according to claim 1, the volume when driven into each material is smaller than that of the round nail, and the blade made by several grooves cuts the material, so that it is easy to drive and the bending is reduced, If the tree is hard to break. The design is also excellent when using a cross-shaped head.

[Brief description of drawings]

FIG. 1 is a side view of a grooved nail.

FIG. 2 is a sectional view of a grooved nail.

FIG. 3 is the head of a grooved nail.

FIG. 4 is a side view and a head of a conventional nail.

Claims (1)

[Scope of utility model registration request] 1. A nail used for fixing wood, aluminum, concrete, iron plate, stainless steel and other materials to a stopper, and a nail driven into each material. The nail is made of each material. , The head of the nail body when driving,
Flat head, round head, or cross-shaped flat head, round head, with a few or many grooves from the head to the tip of the main body. In order to prevent the nail from coming off easily, the part with a little length from the head has the same shape as a conventional round nail. By making the main body as described above, there is strength, the blade made by the groove cuts into the material to be driven, the volume is also smaller than the circle, so the driving is easy and the bending is reduced. When it comes to head, the design is also excellent.
