Tension reducer for cable wrap security device
View Patent ↗A security device includes a housing containing a ratchet mechanism and a rotatable spool for storing a plurality of cable loops which extend outwardly from a plurality of openings formed in the housing and wrapped around the sides of a box-like object. A collar is mounted on the bottom of the housing and has openings adjacent each of the housing opening requiring the cable loops to abruptly change direction after exiting the housing and passing either beneath or above the collar before extending along the secured object. This abrupt change of direction reduces the amount of force which are exerted on the cable loops from being transmitted onto the ratchet mechanism. In alternate embodiments, adjacent cable loops pass through one or a pair of rings which cause a change of direction in the cable loops to reduce the transmission of forces onto the ratchet mechanism.
1. A security device adapted to be placed on an object to prevent said object from being opened, said device comprising:
a housing;
a plurality of cable loops extending outwardly from the housing for placement about the object;
a ratchet mechanism located within the housing and operatively connected to the cable loops, said ratchet mechanism operatively connected to a rotatable spool for maintaining the cable loops tensioned around the object;
a plurality of openings formed in the housing for passage of the cable loops therethrough for placement about the object; and
a tension reducing device operatively engageable with the cable loops generally adjacent the housing openings for abruptly changing the direction of said cable loops after passing of said loops in a generally tangential direction out of the housing openings prior to said loops extending about the object; said tension reducing device including a collar mounted on the housing and formed with a plurality of openings located adjacent to the housing openings requiring the cable loops to abruptly change direction and pass beneath said collar when placed about the object; and wherein the collar is snap-fitted onto the housing by a plurality of tabs formed on one of the housing and collar and engageable in holes formed in the other of the collar and housing.
2. The security device defined in claim 1 wherein the collar is an annular ring having a plurality of arcuate projections; and in which the collar openings are outwardly extending recesses formed in the collar between adjacent pairs of the projections for directing the cable loops beneath the collar and then about the object.
3. The security device defined in claim 1 wherein the abrupt change of direction of the cable loops is generally between 90° and 180°.
4. The security device defined in claim 1 wherein the collar is formed with a plurality of spaced arcuate projections for contacting the cable loops after the cable loops pass out of the housing openings in the generally tangential direction prior to abruptly changing the direction of the cable loops when placed about the object.
5. The security device defined in claim 4 wherein each of the cable loops is located adjacent an inside surface of one of the arcuate projections prior to abruptly changing direction at an end edge of said projection.
6. The security device defined in claim 4 wherein a snap-fit tab is formed on each of the arcuate projections; and in which the collar, arcuate projections and tabs are formed as a one-piece member of a rigid plastic material.
7. In combination an object and a security device removably mounted on the object; said security device having a housing formed with four housing openings and a plurality of cable loops extending from the housing through said openings and wrapped around the object; said security device including a ratchet mechanism contained in the housing and a rotatable spool to which the cable loops are attached; said security device further includes a tension reducing member operatively engaged with the cable loops for abruptly changing the direction of said loops as they exit in a generally tangential direction from the housing and wrap around the object, said tension reducing member includes a collar formed with four openings respectively adjacent the four housing openings for directing the cable loops beneath the collar and then about the object.
8. A security device adapted to be placed on an object to prevent said object from being opened, said device comprising:
a housing;
a plurality of openings formed in the housing;
a plurality of cable loops extending outwardly from the housing through the openings for placement about the object;
a ratchet mechanism located within the housing and operatively connected to the cable loops, said ratchet mechanism operatively connected to a rotatable spool for maintaining the cable loops tensioned around the object;
a tension reducing device operatively engageable with the cable loops generally adjacent the housing openings for abruptly changing the direction of said cable loops after passing of said loops in a generally tangential direction out of the housing openings prior to said loops extending about the object, said tension reducing device including a collar mounted on the housing, said collar having a plurality of upstanding projections which mount the collar in a spaced relationship on the housing and having openings formed in the collar between adjacent pairs of the projections for directing the cable loops through the collar openings and beneath the collar and then about the object requiring the cable loops to abruptly change direction when passing through the collar openings and beneath the collar when placed about the object.
9. The security device defined in claim 8 wherein the collar is snap-fitted onto the housing by a plurality of tabs formed on one of the housing and collar and engageable in holes formed in the other of the collar and housing.
10. The security device defined in claim 8 wherein the collar is snap-fitted onto the housing by a plurality of tabs formed on one of the housing and collar and engageable in holes formed in the other of the collar and housing.
11. A security device adapted to be placed on an object to prevent said object from being opened, said device comprising:
a housing;
a plurality of cable loops extending outwardly from the housing for placement about the object;
a ratchet mechanism located within the housing and operatively connected to the cable loops, said ratchet mechanism operatively connected to a rotatable spool for maintaining the cable loops tensioned around the object;
a plurality of openings formed in the housing for passage of the cable loops therethrough for placement about the object; and
a tension reducing member operatively engageable with the cable loops generally adjacent the housing openings for abruptly changing the direction of the cable loops after passing of the loops out of the housing openings prior to said loops extending about the object, wherein said tension reducing member is snap-fitted to the housing.
