Abstract
Abstract A wheel cover locking assembly comprises a knob in which a plastic bolt is rotatably mounted, the bolt extending through a wheel cover and engaging a nut carried on a bracket affixed to a wheel by means of lug nuts, so that rotation of the bolt locks the wheel cover on the wheel. A cam piece located inside the knob and hidden by a snap-in decorative cover can be rotated by means of a simple key to clutch and de-clutch the knob to and from the bolt. The simplified and economical construction tends to be impervious to water and dirt.

Claim 1
Independent Claim
220 words
A locking assembly for locking a wheel cover in a vehicle wheel secured to a vehicle by a plurality of lug nuts, comprising, in combination: a mounting bracket adapted to be secured under a pair of said lug nuts and to locate a threaded nut axially outwardly from said wheel; a rotatable knob member adapted to seat against said wheel cover; a threaded bolt means rotatably journalled in said knob member and adapted to threadedly engage said threaded nut; and a cam seated within said knob member, said cam being pivotable between a first position at which rotation of said knob member causes rotation of said bolt means and a second position at which rotation of said knob member does not cause rotation of said bolt means, said knob member including first and second overlapping and intercommunicating circular recesses having a common space, said cam piece having a shape adapted to fill the first of said circular recesses but none of said common space when said cam is rotated to said second position, and adapted to fill said common space when said cam is rotated to said first position, said bolt means having a recess conforming to said common space and adapted to be filled by a portion of said cam when said cam is rotated to said first position.
Claim 2
Dependent Claim
220 words
A locking assembly for locking a wheel cover in a vehicle wheel secured to a vehicle by a plurality of lug nuts, comprising, in combination: a mounting bracket adapted to be secured under a pair of said lug nuts and to locate a threaded nut axially outwardly from said wheel; a rotatable knob member adapted to seat against said wheel cover; a threaded bolt means rotatably journalled in said knob member and adapted to threadedly engage said threaded nut; and a cam seated within said knob member, said cam being pivotable between a first position at which rotation of said knob member causes rotation of said bolt means and a second position at which rotation of said knob member does not cause rotation of said bolt means, said knob member including first and second overlapping and intercommunicating circular recesses having a common space, said cam piece having a shape adapted to fill the first of said circular recesses but none of said common space when said cam is rotated to said second position, and adapted to fill said common space when said cam is rotated to said first position, said bolt means having a recess conforming to said common space and adapted to be filled by a portion of said cam when said cam is rotated to said first position.
Claim 3
Dependent Claim
43 words
The assembly according to claim 1 wherein said bolt means has a plurality of recesses each conforming to said common space and any of which may be filled by said portion of said cam when said cam is rotated to said first position.
Claim 4
Dependent Claim
175 words
A locking assembly for locking a wheel cover on a vehicle wheel which is secured to a vehicle by a plurality of lug nuts for rotation of said wheel about an axis, comprising, in combination: a mounting bracket adapted to be secured under a pair of said lug nuts and to locate a threaded nut axially outwardly from said wheel on said axis; a rotatable knob member adapted to seat against a central portion of said wheel cover surrounding said axis; a threaded bolt means journalled in said knob member for rotation about said axis and adapted to threadedly engage said threaded nut; and a cam seated within said rotatable knob member, said cam being pivotable between a first position at which rotation of said knob member causes rotation of said bolt means and a second position at which rotation of said knob member does not cause rotation of said bolt means, said cam comprising a disc pivotable about a pivot axis displaced from and substantially parallel to said axis of rotation of said wheel.
Claim 5
Dependent Claim
175 words
A locking assembly for locking a wheel cover on a vehicle wheel which is secured to a vehicle by a plurality of lug nuts for rotation of said wheel about an axis, comprising, in combination: a mounting bracket adapted to be secured under a pair of said lug nuts and to locate a threaded nut axially outwardly from said wheel on said axis; a rotatable knob member adapted to seat against a central portion of said wheel cover surrounding said axis; a threaded bolt means journalled in said knob member for rotation about said axis and adapted to threadedly engage said threaded nut; and a cam seated within said rotatable knob member, said cam being pivotable between a first position at which rotation of said knob member causes rotation of said bolt means and a second position at which rotation of said knob member does not cause rotation of said bolt means, said cam comprising a disc pivotable about a pivot axis displaced from and substantially parallel to said axis of rotation of said wheel.
Claim 6
Dependent Claim
196 words
