Description

Field of technology

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.

The disadvantage of these famous 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.

A nail / 1 / is known, consisting of a head, a body with screw notches, ending with a pointed tip. A body is a polyhedron whose cross section can have the profile of a regular polygon (triangle, quadrilateral, pentagon or Relo triangle). A steel rod or wire is used to make the multi-walled body. The screw notches are formed by simultaneously pulling or rotating the rod or wire through a corresponding profile hole (matrix) in the cold state. The screw notches have a step equal to (0.6 - 1.2) L, where L is the length of the nail body.

The disadvantage of this nail is that it is easily removed after driving into a body composed of different types of triangles or polygons. Another disadvantage is that when placing screw elements for more difficult removal, the nail is difficult to apply in mass production due to its 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, the upper side of the head being flat, with a recess in the center of the head having the shape of a triangle with protruding 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.

A variant of the nail body is that the rounding of the convex arcs are parts of a spiral, parabola or other geometric curve.

A variant design of the nail body is that the edges of the body have a cross section composed of three protruding arcs, which arcs are rounded, the rounding being part of a circle, spiral, parabola.

Such nails are especially convenient for use in construction in areas subject to natural disasters such as earthquakes, tsunamis, storms and hurricanes.

In addition, it is an advantage that the proposed nails with cross-sections formed by more than three arcs will have a greater resistance to rotation of nailed parts than the currently used mass nails with circular cross-section, in which to prevent rotation of the fastened parts is it is necessary to drive at least two nails.

In addition, the stem with three edges has greater resistance than a stem with a circular cross-section and this will increase the length of the stems of the nails. Also, the greater resistance of the offered nails to bending or driving will allow to replace nails with a large circular cross-section with the offered ones, which will have a smaller cross-section and, accordingly, a smaller mass. The described advantages of the offered nails make them suitable for application in medicine as well, as the size of the introduced foreign bodies in the organisms will be reduced.

An advantage of the nails according to the invention is that they are applicable in mass production due to the specific design of the sides of the body with protruding arcuate sides, which does not require large investments.

The advantage of nails is that the change in the cross section of the body of the nail of the arcs of a circle with arcs of geometric curves (spiral, parabola) allows to approach optimally for different cases of joining with nails of details of various materials, such as different types of wood, plastics and composite materials. The presence of edges on the stem of the offered nails allows to introduce in practice oriented driving of nails - specifically for different cases, in order to obtain their optimal use.
