  • a tool such as a pincer with sharp ends can be introduced, or a tubular piece of softer material can be introduced to copy
  • the profile and by means of these common or improvised tools, the retention piece is removed by rotating it on its axis, which ceases to provide a security or anti-theft element.
  • a nut head or bolt of European origin has a coded head, surrounded by a sleeve whose side walls surround said head, said sleeve having a plastic or permanent deformation at its base that defines a flange annul that sits within a recess in said body, below the height of said coded head.
  • This construction has the serious drawback that for its construction it is necessary to emphasize by means of an instrument for this purpose the lower end of the sleeve, thus creating the annular flange.
  • the sleeve material must have a low creep limit in order to proceed with its construction.
  • the limited or reduced creep limit implies that this sleeve is deformable by means of a clamp or tool for this purpose, locking it, whereby the bolt or nut is removed. That is, this construction is easily violated.
  • lower portion of the linkage body is the portion of the anterior body that is axially disposed and then the head thereof.
  • suitable and complementary tool to the head of the linking body is any means that is complementary to the conformation or profile of the head of said body, allowing the axial rotation of said body on said thread fillet by adjusting or decoupling said body from bonding
  • engaging area this is called throughout this specification and claims the portion of the bolt or nut that performs the action of tightening and linking between the various parts to be joined. This portion of the bolt can be monolithic to it. or it may be constituted by a supplementary piece.
  • the AR No. 244,135 patent provides at least one low-rise and coaxial disc with the longitudinal axis of the bolt or nut body on the bolt or nut head.
  • Coaxial discs serve as a guide for the removal or fixing tool.
  • this safety piece cannot exceed 27 to 30 mm and its height must not exceed that of the head of a conventional nut or bolt used to secure the tires of the Vehicle wheels. Also and as far as possible, the mass of this bolt should be equivalent to that of the original bolt.
  • FIG. 1 shows in partial longitudinal section a first construction of the invention, showing the adjustment body, which consists of a bolt arranged assembled to the bushing and to a body that defines the seating area.
  • FIG. 2 shows the bushing, the body of the seating area and the "O" ring in an open and isolated position;
  • Figure 4 shows in longitudinal section an example of the construction of Figure 1, with a different seat body
  • FIG. 5 shows in longitudinal section the construction of Figure 1;

  • the invention covers both nuts and safety bolts, so that any of the constructions explained and illustrated below are useful for explaining any of both variants: if it is a bolt, it will have as a means of adjustment a end with a thread steak male, and if it is a nut, it will have a drill with a female thread.
  • Figure 1 shows in longitudinal section a construction of the linkage body (1) that schematizes a bolt which in its lower portion has a thread fillet (2), coaxial with the longitudinal axis XX.
  • This first construction of the invention in the upper portion or body head (7) (See Figure 3), has from the bottom towards its upper end, a first cylindrical portion (3) and a second cylindrical portion (4) both arranged coaxial to the longitudinal axis XX, followed by a third cylindrical portion of disc (5) eccentric with respect to said longitudinal axis, with YY axis parallel to XX and displaced by a distance "e”. (See Figures 4 and 5).
  • the cylindrical portions (3, 4) and the eccentric (5) are monolithic, that is, they are the same piece, but if desired, they can be constructed as separate pieces and then immovably linked together.
  • This bushing forms a body of concentric revolution to the aforementioned axial longitudinal axis XX that defines a bushing formed by an internally hollow side skirt whose side wall determines an inner cylindrical surface that delimits an inner volume (8), and has at its upper end (9 ) a circular inlet whose height is substantially coincident with the height of the eccentric cylindrical portion (5) resulting in said inlet (9) communicating to the cylindrical interior (8) and open to the outside.
  • the inner cylindrical surface of the bushing (6) has a first section (11), followed by a second section (12) of smaller diameter that defines a first step (13), followed by a third section ( 14) of smaller diameter that defines a second step (15).
  • This configuration is coincident and complementary to the second cylindrical portion (4) whose lateral surface (16) supports rotatably on the cylindrical surface (12) while the lateral surface (17) of the first cylindrical portion (3) seats rotatably against the cylindrical surface (14) both arranged coaxial to the longitudinal axis XX.
  • the inner wall of said skirt at its lower end, following the upper end of said passage (26), has a circular seat (27) within which the said cylindrical disc (3) freely rotates on its axis XX while at its lower end through the passage (26) the lower end (6) of the linkage body (1) emerges, determining a seating area capable of imprisoning the parts to be connected by means of the device of the invention. It is noted that this seat (27) at the same time establishes a stop that limits the displacement of the bushing (20) upwards. Moreover, in this particular construction, the diameter of the axial cylindrical portion (5) and hence of its seat (27) is smaller than the diameter of the internal walls (23).
  • Figures 8, 9 and 10 illustrate a third construction of the invention in which Figure 8 shows in section a body of the seating area (35), which with the same references has the same attributes already explained, with the addition of have an inclined annular plane (36).
  • Figure 9 shows in section the bushing (6) and the rod (2) of the bolt (1) has an annular projection (37) in the form of a plane inclined towards the threaded end, projection that sits in the annular recess (27) of the body (35), ensuring the light (e) between (19) and (30).
  • Figure 18 shows a seventh construction of the invention, applied to a sheet metal rim (r).
  • Figure 19 illustrates in partial section an eighth construction of the invention. It is indicated with (56) an end cylindrical body coaxial to the XX axis that ends in a conical trunk surface (53) or a spherical portion (not illustrated).
