Abstract

An apparatus includes: a head; a metal wire having a first end coupled to the head and a second end coupled to a stop member; and a body having a cavity for receiving and locking the head such that when the head is locked in the cavity it cannot be removed without destroying the apparatus, wherein the head and the metal wire are operable to pass through one or more apertures of an object and the head is operable to lock in the cavity such that the body and the stop member retain the wire in engagement with the aperture and maintain the apparatus locked to the object.

Claims

1. An apparatus, comprising an elongated member that includes a plurality of sections, the plurality of sections comprises two end sections and at least one middle section, each separated by a stop member, each section comprises a shaft, at least one head and at least one breaking portion, and the end sections comprises a first end having a head, each oppositely directed from one another and a second end connected to a stop member;

a body having at least one aperture and at least one cavity communicating with the aperture for receiving, in a receiving direction, and locking the respective heads such that, when locked in the cavity, the heads cannot be removed in a direction opposite the receiving direction without destroying the apparatus, the cavity having a length capable of receiving and retaining more than one of the heads in axial alignment such that a first of the heads may be received and locked within the body and subsequently permit the first head to be urged further in the receiving direction by a second of the heads such that the second head is locked within the body, thereby permitting multiple reusable locking actions;

wherein the head and the elongate member are operable to pass through one or more apertures of an object and the heads are operable to lock in the cavity such that the body is locked to the object;

wherein a given section may be broken at the breaking portion after the head thereof has been locked into the cavity, a further one of the heads may be inserted into the cavity urging the head of the given section forward, and the further head is locked within the cavity;

wherein the at least one breaking portion is disposed between one or more heads and the stop member, and the stop member is sized and shaped so as not to be receivable into the body.

2. The apparatus of claim 1, wherein the at least one aperture includes an input, and the cavity includes a split ring in axial alignment with the aperture and a channel operable to engage an outer edge of the split ring such that the split ring is prevented from moving in an axial direction.

3. The apparatus of claim 2, wherein at least one of the heads comprises a first end having a beveled forward portion and a second end, the split ring being operable to permit the beveled forward portion of the head to pass therethrough in an insertion direction and the split ring being operable to prevent the beveled forward portion from being removed after the beveled forward portion passes therethrough.

4. The apparatus of claim 3, wherein:

the body includes a stop surface oppositely disposed within the cavity from the input and spaced away from the split ring such that the stop surface limits axial movement of the head into the cavity and the split ring limits axial movement of the head out of the cavity, but the head is permitted some degree of axial movement.

5. The apparatus of claim 1, wherein the body includes a further aperture and at least one further cavity communicating with the further aperture for receiving, in a receiving direction, and locking at least a third one of the heads such that, when locked in the further cavity, the third head cannot be removed in a direction opposite the receiving direction without destroying the apparatus.

6. The apparatus of claim 5, wherein the further cavity is operable to receive and lock the third head and subsequently permit the third head to be urged further in the receiving direction by a fourth of the heads such that the third head is locked within the body.

7. The apparatus of claim 6, wherein the further cavity is in axial alignment with the at least one aperture.

8. The apparatus of claim 7, wherein the further cavity is oppositely directed to the at least one aperture such that the respective receiving directions of the at least one aperture and the further aperture are opposite to one another.

9. The apparatus of claim 1, wherein the first and second heads are coupled to one another in axial alignment and may separated from one another for multiple locking actions into the at least one aperture.

10. The apparatus of claim 9, wherein the first and second heads are oppositely directed.

11. The apparatus of claim 9, wherein the first and second heads are oriented in a same direction.

12. The apparatus of claim 1, wherein at least one of the sections includes a further breaking portion disposed on an opposite side of the stop member from the head such that the stop member of the given section may be broken from the shaft to enable the further head for insertion into the cavity.
