Description

The invention relates to a "nail" that will find application in construction, furniture and household.

BACKGROUND OF THE INVENTION

A nail with a circular cross-section of the body is known, on which a head is formed at its upper end, and the lower end of the body ends with a shaped pyramidal tip. There are varieties of nails whose body cross section is different from that of a circle, whose heads and lower end are differently shaped. Nails are also known, consisting of several parts, which dissolve in the driven materials during driving. Nails are known whose body is grooved along part or along the entire length of the body, as well as with bodies twisted in a helical line and with curled edges transversely along the axis of the body. "Nail" / 1 / is known, whose body is an equilateral triangle with straight or concave arched walls.

The disadvantage of the known nails is that they are easily removed after driving due to their round cross section. Another disadvantage of the famous nails is the easy breakage of the triangular tips due to their reduced cross section. In addition, the disadvantage is that they cannot be applied in mass production due to their complex manufacture.

Technical essence of the invention

The object of the invention is to provide a nail with an increased circumference of the body, difficult to remove and with a shape applicable in mass production.

The problem is solved by creating a nail consisting of a body in the shape of an equilateral triangle, the sides of which are convex outwards and represent arcs of a circle. At the upper end of the body is formed a head of three convex parts of a sphere, the edges of which coincide with the edges of the equilateral triangle of the body, and on the upper side the head is flat, with a recess in the center of the head having the shape of a triangle with convex outward sides representing arcs of a circle. At its lower end, the body ends with a vertex shaped like a triangular spheroidal pyramid, the sides of which are parts of a sphere, and the edges are arcs of a circle and coincide with the edges of the body.
