Abstract
Abstract A cargo stabilizing device has a channel member with studs extending from one wall to engage keyhole-shaped holes spaced a certain distance apart in a support. A movable member can slide in the channel member and has teeth that can be engaged by a panel on the channel member to lock the movable member in any of the more closely spaced positions defined by the spacing between the teeth. The movable member has a further adjustable member with a surface that engages the cargo to hold it in place. The adjustable member can be moved to any position within a range at least as long as the distance between the teeth on the movable means. Selection of the holes into which to engage the studs, and selection of a specific tooth, and setting the adjustable member allows the surface of the latter to be placed at any point in the entire range of positions possible within the locations available in the entire set of holes in the support.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
164 words
A restraining device to be held rigidly but releasably on a support member at any of a plurality of locations spaced apart from one another by a first distance in a predetermined direction to limit movement of cargo in that direction, the restraining device comprising: first engagement means at each of the locations; main movable means; second engagement means firmly joined to the main movable means to engage the first engagement means at any of the locations; a movable member movably mounted with respect to the main movable means; a plurality of teeth on the movable member, corresponding locations on adjacent teeth being spaced apart from one another by a second distance less than the first distance; and a pawl mounted on the main movable means and movable into engagement with any accessible tooth as determined by the position of the movable member to block the movable member in a fixed position relative to the main movable means according to which tooth is engaged.
Claim 2
Dependent Claim
164 words
A restraining device to be held rigidly but releasably on a support member at any of a plurality of locations spaced apart from one another by a first distance in a predetermined direction to limit movement of cargo in that direction, the restraining device comprising: first engagement means at each of the locations; main movable means; second engagement means firmly joined to the main movable means to engage the first engagement means at any of the locations; a movable member movably mounted with respect to the main movable means; a plurality of teeth on the movable member, corresponding locations on adjacent teeth being spaced apart from one another by a second distance less than the first distance; and a pawl mounted on the main movable means and movable into engagement with any accessible tooth as determined by the position of the movable member to block the movable member in a fixed position relative to the main movable means according to which tooth is engaged.
Claim 3
Dependent Claim
40 words
The restraining device of claim 1, in which the number of the teeth times the distance from a location on one tooth to the corresponding location on the next adjacent tooth is at least as great as the first distance.
Claim 4
Dependent Claim
34 words
The restraining device of claim 1, in which the pawl is pivotally mounted on the channel means to move the accessible tooth a fourth distance that can be as great as the second distance.
Claim 5
Dependent Claim
194 words
The restraining device of claim 1, in which the support member is an elongated channel member comprising a raised central rib that has a plurality of holes spaced apart by the first distance in a longitudinal direction, and the engagement means comprises first and second studs rigidly attached to the channel means and extending from an external surface thereof and spaced apart in the longitudinal direction by said first distance to fit into two of the holes in the central rib of the channel member to keep the engagement means aligned with the channel member and in fixed position thereon, each of the studs having an enlarged head shaped to fit through any of the holes in the central rib and a neck of reduced diameter, the neck having a length substantially equal to the thickness of the rib to allow the neck to be forced against a part of the wall defining the respective hole, whereby the stud can be locked in the respective hole by engagement of said part of the wall between the juxtaposed surfaces of the head and the external surface of the channel means without rotating the channel means.
Claim 6
Dependent Claim
66 words
The restraining device of claim 4, in which each of the holes is formed by: a central wall portion defining an open area large enough to receive the head of one of the studs, and diametrically opposite slots extending in the direction toward the next such hole, each slot being as wide as the neck of a stud but narrower than the head of a stud.
Claim 7
Dependent Claim
46 words
The restraining device of claim 1, comprising, in addition, resiliently biased latching means, to hold the handle means fast to the channel means when the handle means is in position to cause the pawl to press the accessible tooth to the forwardmost location of the pawl.
Claim 8
Dependent Claim
61 words
The restraining device of claim 6, in which the handle means comprises a hollow tube and the latching means comprises: a plunger movable longitudinally in the hollow tube; and an external hook located to engage the second end of the wall means when the handle means is pivoted to the end of its range of its travel toward the wall means.
Claim 9
Dependent Claim
74 words
The restraining device of claim 6, in which the external hook is attached to the plunger to move therewith relative to the tube, and the tube and the plunger of the handle means have holes positioned to be in alignment with each other when the hook engages the second end of the wall means, whereby the plunger and the tube can be locked together to keep the movable member locked in a fixed position.
Claim 10
Dependent Claim
52 words
The restraining device of claim 8, in which the axial depth of the threaded hole and the axial length of the threaded plug are each greater than the distance between corresponding points on adjacent ones of the teeth, whereby the threaded plug can be moved a distance greater than the second distance.
Claim 11
Dependent Claim
34 words
The restraining device of claim 1, in which the front end of the movable member has a longitudinal, internally threaded hole, and the adjustable member comprises an externally threaded plug threaded into the hole.
Claim 12
Dependent Claim
36 words
The restraining device of claim 1, comprising adjustable means mounted on the movable member and extending from the front of the movable member, the adjustable means being movable by a third distance in the predetermined direction.
Claim 13
Dependent Claim
32 words
The restraining device of claim 11, in which the maximum value of the third distance by which the adjustable means can be moved is at least as great as the second distance.
