Abstract

A personal property securement device mountable to a vehicle may comprise a cable housing with a safety port that defines a passage extending from internal to external the housing. A cable may be threaded through the passage with one end fixed to a cable retention knob external the housing and the other end fixed to a reel that may be disposed for rotation within the housing. A power spring may present a torque on the reel to enable retrievable winding and tensioned unwinding of the cable. The property securement device may further comprise a ratchet mechanism in cooperation with the reel to release tensioning of the cable at given incremental extractions.

Claims

1. A property securement device, comprising:

a housing;

a safety port defining a passage of given diameter and length extending from internal to external the housing;

a cable threaded through the safety port comprising a cross-sectional diameter less than the diameter of the passage;

a cable retention knob fixed to a first end of the cable;

a reel within the housing, the second end of the cable secured to the reel and the reel operable to wind a length of the cable for storage; and

a power spring to apply a rotational force on the reel to enable tensioned winding and unwinding of the cable;

the safety port of the given diameter and length for the passage operatively configured to be operable upon and cooperatively with the cable to apply a frictional braking force and slow retraction of the cable when at least a given length thereof is external the housing and freed while under the influence of the power spring for tensioned rewind,

further comprising a ratchet mechanism operable in cooperation with the reel to release tensioning of the cable at given incremental extractions of the cable from the housing;

the ratchet mechanism further operable in cooperation with the reel to define neutral zones along substantially periodic intervals of the cable extension, wherein a periodic interval of the periodic intervals is defined by multiple of said given incremental extractions, the ratchet mechanism further operable collectively with the wheel when within a given neutral zone of the neutral zones to enable freeing of the reel for permitting reversal of reel rotation and restored tension for cable retraction under the influence of the power spring; and

in which the housing is operatively configured to be mountable to a vehicle.

2. The device of claim 1, in which at least one wall of the housing defines an opening, and said device further comprises a bushing disposed within the opening to define the passage.

3. The device of claim 2, in which the diameter of the passage defined through the bushing is (i) sufficiently great to permit substantially free passage of the cable when the cable is presented to the passage with an angular alignment relative to a central axis of the passage of magnitude less than about five degrees, and (ii) sufficiently small to cause the cable to press against at least one of the walls that define the passage when the cable is presented thereto with an angular alignment relative the central axis of magnitude greater than about five degrees.

4. The device of claim 3, in which the cable comprises an outer surface;

the bushing for the safety port per a cross-sectional view along a length of the passage defines an edge at an annular opening thereto, the edge comprising a given radius of curvature operable with the outer surface of the cable to define a coefficient of friction therebetween; and

at least one of the parameters of the group consisting of;

a clearance of the passage relative to the cable, the length of the passage, and the coefficient of friction between the bushing and the outer surface of the cable, comprises magnitude(s) sufficient to enable formation of a resistive force on the cable greater than a take-up or winding force deliverable to the cable by the power spring when a given length of the cable is released external the housing during rewind.

5. The device of claim 4, in which the radius of curvature to the edge is formed by an edge de-burring treatment.

6. The device of claim 4, in which the cable comprises a coating of polymer material;

at least a portion of the bushing that defines the edge comprises one material of the group of materials consisting of metal and plastic; and

the coefficient of friction is defined between the polymer material coating of the cable relative to said one material defining the edge of the bushing.

7. The device of claim 6, in which the cable further comprises a multi-stranded metal structure bundled within a PVC sleeve as the coating of polymer material.

8. The device of claim 7, in which the given length of the cable external the housing is predetermined based on a weight thereof operable in combination with the coefficient of friction to establish the resistive force greater than the take-up force deliverable to the cable by the power spring during rewind.

9. The device of claim 8, in which the given length for the cable to establish the weight is at least about three feet, and the cable further comprises a total length greater than about six feet.

10. The device of claim 3, in which the cable retention knob comprises:

a locking end operable collectively with a lock mechanism for enabling securement;

a cylindrical portion in contiguous relationship with the locking end and defining a mid-section thereto; and

a butt-end joined to the cable and in contiguous relationship with the cylindrical portion, the butt-end defining an angular flare-out shoulder between its junction with the cable and the cylindrical portion and operable to seat with non-binding engagement within a tapered opening of the bushing proximate an entry/exit to the passage.

11. The device of claim 10, in which the locking end defines an elongated tab that extends axially from the cylindrical portion and defines an elongated slot of width sufficient to receive either a fold of the cable or a shaft of a padlock.

12. The device of claim 11, in which the power spring is assembled in the reel with a pre-bias sufficiently great to present a torque on the reel to forcibly seat the butt-end of the cable retention knob against a countersunk recess of the bushing that defines the taper when the cable is fully retrieved.

13. A property securement device, comprising:

a housing;

a safety port defining a passage of given diameter and length extending from internal to external the housing;
