Abstract

Abstract A DEVICE FOR RELEASABLY SECURING ONE UNIT AGAINST A SECOND UNIT Abstract of the Disclosure A device is provided for use in releasably securing one unit (e.g., the rear end of a truck vehicle) against a second unit (e.g., a loading dock). The device comprises an elongated member mounted for controlled endwise movement relative to a locking assembly, the latter being adjustably mounted on the second unit. Carried by the elongated member and extending from one end thereof is an attaching means which is adapted to be releasably secured to the one unit when the elongated member is disposed in a predetermined relative position with respect to the locking assembly. A friction means is adjustably mounted within the locking assembly for movement between operative and inoperative positions. When the friction means is in an operative position, the exterior of the elongated member is fric-tionally engaged thereby so that the elongated member can be moved endwise in only one direction, i.e., away from the one end of the elongated member from which the attaching means extends. When the friction means is in an inoperative position, the elongated member can be moved in either end-wise direction relative to the locking assembly. The friction means is biased to normally assume an operative position. Manually actuated means is carried on the locking assembly for moving the friction means from an operative position to an inoperative position.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 215 words
A device for releasably securing one unit against a second unit, said device comprising: an elon-gated member; first means carried on one end of said elon-gated member; attaching means carried by said elongated member and having one end thereof extending from a second end of said elongated member and being adapted to be re-leasably connected to the one unit, said attaching means having a second end engaging said first means, said first means being movable relative to said elongated member in response to a predetermined pulling force exerted on said one end of said attaching means; and a locking assembly on which said elongated member is mounted for controlled end-wise movement, said locking assembly being adjustably mountable on the second unit and including friction means movable independently of said elongated member between operative and inoperative positions, said friction means, when in said operative position, engaging said elongated member and allowing endwise movement thereof only in a direction toward said one end of said elongated member, and, when in said inoperative position, allowing endwise movement in either direction, second means engaging said friction means and biasing said friction means into said operative position, and manually actuated means adjustable independently of said elongated member for moving said friction means from said operative position to said inoperative position.
Claim 2
Independent Claim 215 words
A device for releasably securing one unit against a second unit, said device comprising: an elon-gated member; first means carried on one end of said elon-gated member; attaching means carried by said elongated member and having one end thereof extending from a second end of said elongated member and being adapted to be re-leasably connected to the one unit, said attaching means having a second end engaging said first means, said first means being movable relative to said elongated member in response to a predetermined pulling force exerted on said one end of said attaching means; and a locking assembly on which said elongated member is mounted for controlled end-wise movement, said locking assembly being adjustably mountable on the second unit and including friction means movable independently of said elongated member between operative and inoperative positions, said friction means, when in said operative position, engaging said elongated member and allowing endwise movement thereof only in a direction toward said one end of said elongated member, and, when in said inoperative position, allowing endwise movement in either direction, second means engaging said friction means and biasing said friction means into said operative position, and manually actuated means adjustable independently of said elongated member for moving said friction means from said operative position to said inoperative position.
Claim 3
Dependent Claim 76 words
The device of claim 1 wherein said friction means includes a plurality of confined platelike elements arranged in substantially face-to-face relation, each element being provided with an opening through which said elongated member extends; said elements assuming an askewed relation with respect to the longitudinal axis of said elongated member and having perimetric segments of the openings in frictional engagement with the exterior of said elongated member when said friction means is in said operative position.
Claim 4
Dependent Claim 73 words
The device of claim 2 wherein said locking assembly includes a housing in which at least a portion of each platelike element is confined, said elongated member extending through said housing and being movable relative thereto depending upon the positioning of said friction means; said platelike elements being tiltable as a unit about corresponding edges of the elements as a fulcrum, when said friction means is being moved between operative and inoperative positions.
Claim 5
Dependent Claim 34 words
The device of claim 1 wherein said first means is endwise movable toward said second end of said elongated member in response to said predetermined pulling force exerted on said attaching means one end.
Claim 6
Dependent Claim 49 words
The device of claim 4 wherein said first means includes a switch means actuated by said elongated member in response to endwise movement of said first means toward said second end due to said predetermined pulling force for effecting adjustment of a signal means to a predetermined first condition.
Claim 7
Dependent Claim 36 words
The device of claim 5 wherein a portion of said switch means is in rolling contact with an exterior portion of said elongated member, said exterior portion of said elongated member having a cam-like surface configura-tion.
Claim 8
Dependent Claim 35 words
The device of claim 1 wherein said locking assembly is mounted to swivel on the second unit with the axis of swivel being substantially perpendicular to and intersecting the longitudinal axis of said elongated member.
Claim 9
Dependent Claim 56 words
The device of claim 1 wherein said elongated member is of tubular configuration and said attaching means has a portion thereof extending through said elongated member and said second end of said attaching means is provided with a stop means, said stop means being slideably engageable with said first means but being impassable with respect thereto.
Claim 10
Dependent Claim 50 words
The device of claim 5 wherein said first means, when said predetermined pulling force exerted on said attaching means is released, is biased to assume a pre-determined position with respect to the end of said elon-gated member whereby said switch means adjusts said signal means to a predetermined second condition.
Claim 11
Dependent Claim 56 words
The device of claim 9 wherein said bias of said first means is effected by a spring disposed inter-mediate a portion of said first means and said one end of said elongated member, the biasing force of said spring varying in response to the amount of movement of said first means relative to said elongated member.
