Definitions

  • This invention provides a security seal of the padlock type, in which a plastic body is provided with a pair of internal cavities opening to one end of the body, and a wire shackle having legs with reverse bent end portions for locking the legs in the shackle cavities.
  • each shackle leg is provided with a bend forming a tool blocking portion which extends completely across the cavity, said bend being positioned on the legs to become positioned just below the surface of the housing when the shackle is fully assembled.
  • Such bend might be straightened by pulling on the shackle leg with a pair of pliers or the like, after which such a tool could be inserted.
  • the extreme ends of the reversely bent portion are sharpened, and the seal body is provided with a groove so positioned that when a shackle leg is pulled in an attempt to straighten the wire, the ends of the reversely bent portions pierce the plastic body and extend into the groove, where they are clearly visible.
  • seal 10 of the padlock type comprising a plastic seal body 12 and a shackle 14 formed of spring wire.
  • the body 12 is provided with a pair of spaced apertures 16 and 18 which extend into the body from the top surface 20 thereof, and a pair of grooves 22, 23, disposed on opposite sides of the body, said grooves being positioned generally medially between the apertures.
  • the shackle 14 is generally Ushaped forming a long leg 24 and a short leg 26, the legs having bights 28 and 30 forming reversely bent end portions 32 and 34, the reversely bent end portions having extreme ends 36 and 38 which are provided with sharpened ends 36 and 38 by being cut at an angle for a purpose to appear hereinafter.
  • the apertures 16 and 18 have a width substantially the same as the diameter of the wire of which the shackle 14 is made, and a length such that when the ends of the shackle legs are pushed into the apertures, the reversely bent end portions 32, 34 are maintained in a flexed condition so that the sharpened ends 36, 38, bear against the inner walls 40 and 42 of apertures 16 and 18 respectively.
  • the seal 10 is normally supplied to the user with the long leg 24 inserted into the aperture 16 and the bight 30 of the shorter leg projecting into the aperture 18, but not so far that the end 38 of the short leg has entered the aperture, (see Figure 1) so that the short leg may be easily removed from the aperture to enable the shackle leg to be passed through a staple 44 or the like of an article to be sealed.
  • the bight 30 may be re-inserted into the aperture 18, and both legs pushed into the body so that both reversely bent ends are flexed by engagement with the end walls of the aperture. (See Figure 3).
  • the width of the apertures 16, 18, is the same as the diameter of the wire of which the shackle is made and about the same width as that of the strip 46 of material disposed between the grooves 20, 22, to provide a firm support for the pressure of the ends 36, 38, to prevent the pressure of the end of the leg against the plastic from breaking through the aperture wall under conditions of elevated temperature.
  • seals of this general type might be defeated by the insertion of a suitable tool, such as a thin piece of steel, into one of the apertures between the leg and the outside wall of the aperture.
  • a suitable tool such as a thin piece of steel
  • the leg might be forced toward the inner wall, which could tend to flatten the reverse bend portion against said opposite wall.
  • the tool could be removed and the leg could then be drawn out of the aperture without the sharp end of the shackle catching on the inner wall of the aperture, and without leaving evidence of tampering.
  • each leg of the shackle is provided with a laterally inwardly extending U-shaped protrusion 50 formed by a first leg portion 52, a substantially U-shaped bend 54, and a second leg portion 56.
  • the first or upper leg portion 52 of the U-shaped portion is substantially perpendicular to the shackle leg from which it is formed.
  • the second leg portion 54 of the U-shaped lateral protrusion is inclined slightly downwardly, however this leg also could be perpendicular to the shackle leg, if such shape could be provided by the wire bending machinery used to manufacture the shackle.
  • the protrusion has dimensions such that it completely spans the aperture and fits tightly between the sidewalls thereof.
  • a lateral extension in the shackle leg is shown in U.S. patent 3,375,033 to Moberg.
  • the extension shown in Moberg does not completely fill the aperture, and due to the fact that the legs of the lateral extension (not numbered) in Moberg are both inclined at a substantial angle to the side wall of the aperture, it would be possible for a tool to be inserted to first flatten the Moberg protrusion, and then a second thicker tool could be used to force the bight against the inner wall of the aperture to increase the amount bend in said bight for the purpose previously described.
  • the ends 36, 38 of the reversely bent ends are preferably beveled at an angle and in a direction such that when tension is applied to the legs, the ends will pierce the walls 40, 42 at the inner ends of the apertures, and the bevel on the ends will tend to force the ends outwardly so that they enter the groove at or about the corner of the aperture against which the sharp edge of the bevel is bearing.
  • one shackle leg may be permanently attached to the body in some other manner, in which case only one aperture and one locking shackle may be provided.
