ABSTRACT:
A holder for bicycle chains consisting of two primary and necessary elements, see drawing 1, the outwardly curved channel shaped chain retainer element 1, and the elongated box shaped dropout receiver element 2, these two elements are integrated to form a mechanical structure, or chain holder, which may be used to retain a bicycle drive chain upon the bicycle frame dropout thus freeing the bicycle sprocket assembly from its chain and thereby facilitating the removal and reinstallation of the bicycle rear wheel almost as if the chain were not there.
A holder for bicycle chains embodying the above primary elements 1 and 2 plus a secondary element 3 which is a handle, said handle provides good hand control of the chain holder and also provides a spring action snap on-off effect to retain the holder on the chain during a manipulation of the chain by the chain holder.
A holder for bicycle chains embodying the above three elements which allows the user to remove and reinstall the rear wheel of a bicycle as above without having to touch the bicycle drive chain with hands or any manipulative object other than my invention chain holder.
A holder for bicycle chains by the use of which time may be saved during the removal and reinstallation of the rear wheel of a bicycle. A holder for bicycle chains which is pocket sized and weighs less than one half ounce, and is a one piece injection molding.
