Abstract: An all plastic fastener adapted, in one embodiment, for use as a seal for a coin bag or the like, and in another embodiment as a cable tie or the like.The seal comprises a housing having an aperture therethrough and an integral shackle extending from the housing for insertion into the housing opening. The shackle has ratchet teeth along the outer edges, and the housing has internal means for engaging the ratchet teeth when the shackle is pulled through the opening, to prevent reverse movement of the shackle in the housing. In a preferred embodiment of the invention the shackle has an axial slot disposed in the portion having the teeth to allow the sides of the shackle to flex together when it is drawn through the housing. When used as a security seal, a locking member may be inserted into the slot between the shackle portions in the housing to maintain them pressed outwardly into engagement with the locking members in the housing.

Abstract: A double-action hinge for single-hinge top-mounting flexible or semi-flexible doors, of a type mountable on an upright laterally-facing door jamb support, having an axis of hinge-pivot extending uprightly substantially parallel with a mounting door jamb support, with the upper hinge pivot being fixed to a point of and mounting for pivotal rotation as a hinge-mounted door swings to and from in double action through a doorway space framed by a door jamb, and the lower hinge pivot structure being mounted to move freely along an outwardly-extending elongated slot space of a slot-forming lower hinge-support structure permitting a lower end of the hinge axis to move-away from the door jamb support structure when the door swings away from a center position, and an abutting structure having spaced-apart surface portions adjacent the door jamb support structure being mounted on the lower hinge pivot structure fixedly such that the abutting structure turns as the hinge pivots as in opening the door one direction or the

Abstract: A security seal of the type having a housing with an opening to receive a flat strap type of shackle, in which the shackle has an aperture near the end, and said housing has internal means for engaging the shackle to prevent removal after the shackle is properly inserted. The internal means comprises deformable legs which are so deformed by the insertion of the strap end that a free end of one locking leg is caused to move through the aperture of the inserted strap to lock it against removal. In one embodiment of the invention the locking leg has hook means on the free end engaging a stationary portion of the internal structure after it has passed through the strap opening. In another embodiment of the invention two sets of deformable legs are provided so that both ends of a shackle may be engaged in the housing, thereby allowing the user of the seal to provide his own shackles with his own numbering system.
