Cycle lock arrangement

Claim 2

In a locking device for a cycle having a fork, a wheel mounted in the fork, and a brake disc, with opening means extending therethrough, secured to said wheel outboardly thereof, the combination of: (a) a housing member including a body having a cavity therein, open at only one side thereof, and adapted to have said one side mounted against an outboard surface of said disc adajcent said opening means; (b) a retaining member including: (i) an inboard portion adapted to be mounted against an inboard surface of said disc adjacent said opening means; (ii) an integral outboard portion adapted to extend from said inboard portion, through said opening means and into said housing member cavity; (c) said housing member also including a lock element mounted for movement within said cavity into and out of engagement with the outboard portion of said retaining member to keep said disc snugly positioned between opposed surfaces of said retaining member inboard portion and said housing member body; (d) means for moving said lock element into and out of engagement with said retaining member outboard portion.

Claim 3

A locking device according to claim 1, wherein said retaining member outboard portion is in the form of a closed loop.

Claim 4

A locking device according to claim 1, wherein said retaining member outboard portion is formed by a pair of generally parallel side elements and a removable pin extending therebetween.

Claim 5

A locking device according to claim 1, wherein said retaining member is a unitary structure.

Claim 6

A locking device according to claim 4, wherein said retaining member includes a center element, a pair of side elements extending from opposite ends of said center element and normal thereto, and a pair of end elements extending from corresponding ends of respective side elements and normal thereto.

Claim 7

A locking device according to claim 1, wherein said lock element is key actuated.

Claim 8

A locking device according to claim 1, wherein said retaining member includes a U-shaped structure and a removable pin interconnecting free ends of said structure.

Claim 9

A locking device according to claim 1, wherein said retaining member is in the form of a generally flat, T-shaped bar having an opening in an outboard portion thereof for receiving said lock element.

Claim 10

In a locking device for a cycle having a fork, a wheel mounted in the fork, and a brake disc, with opening means extending therethrough, secured to said wheel outboardly thereof, the combination of: (a) a housing member including a body having a cavity therein, open at only one side thereof, and adapted to have said one side mounted against an outboard surface of said disc adjacent said opening means; (b) a one-piece, generally flat, T-shaped retaining member including: (i) an inboard portion adapted to be mounted against an inboard surface of said disc adjacent said opening means; (ii) an integral outboard portion adapted to extend from said inboard portion, through said opening means and into said housing member cavity and having an aperture therein; (c) said housing member also including a lock element mounted for movement within said cavity into and out of the aperture of the outboard portion of said retaining member to keep said disc snugly positioned between opposed surfaces of said retaining member inboard portion and said housing member body; (d) means for moving said lock element into and out of said retaining member outboard portion aperature.

Claim 11

In a locking device for a cycle having a fork, a wheel mounted in the fork, and a brake disc, with opening means extending therethrough, secured to said wheel outboardly thereof, the combination of: (a) a housing member including a body having a cavity therein, open at only one side thereof, and adapted to have said one side mounted against an outboard surface of said disc adjacent said opening means; (b) a one-piece, generally flat, T-shaped retaining member including: (i) an inboard portion adapted to be mounted against an inboard surface of said disc adjacent said opening means; (ii) an integral outboard portion adapted to extend from said inboard portion, through said opening means and into said housing member cavity and having an aperture therein; (c) said housing member also including a lock element mounted for movement within said cavity into and out of the aperture of the outboard portion of said retaining member to keep said disc snugly positioned between opposed surfaces of said retaining member inboard portion and said housing member body; (d) means for moving said lock element into and out of said retaining member outboard portion aperature.
