Abstract

A lock secured to a surface for releasably retaining a motorcycle thereon. The lock includes a pair of outer tubular members secured to the surface. The outer members each enclose a height adjustment bar secured to the lower end of the outer member. The height adjustment bars each include a number of laterally extending pins spaced along the length of the bar. A pair of inner tubular members including a keyway secured to a lower end of the inner member are slidably insertable into the outer members. The keyways pass around the pins on the height adjustment bar until the inner members are rotated to engage the keyways with a selected pin on the respective bars. Each inner member also includes a pair of opposed openings adjacent the upper end of the inner member that are aligned when the inner members are placed in the engaged position. After the motorcycle is placed between the engaged outer and inner members, a locking rod is inserted through one of the inner members, through the frame of the motorcycle, and through the opposite inner member. The locking rod includes a stop plate at one end to properly position the rod between the inner members and a locking bore opposite the stop member which receives a releasable locking member such as a padlock that selectively retains the locking rod in engagement with the inner members.

A method for locking a vehicle to a surface comprising the steps of:

a) providing a pair of outer tubular members having a pair of height adjustment bars attached to one end and extending therethrough, the adjustment bars including a number of spaced, laterally extending pins along its length;
b) securing the outer tubular members to a surface;
c) placing the vehicle between the outer tubular members;
d) providing first and second inner tubular members having a keyway at a lower end and a pair of opposed openings adjacent an upper end;
e) inserting the lower end of each inner tubular member into the respective outer tubular member around the adjustment bar such that the keyway passes around the pins and the adjustment bar until the inner member is positioned within the outer member a desired distance;
f) rotating each inner tubular member within the outer tubular members to engage the keyway with a selected pin on each adjustment bar to maintain the inner member in position with respect to the outer members and the vehicle, and to align the opposed openings in each inner member;
g) inserting one end of a locking rod having a stop ring at the opposite end successively through the openings the first inner tubular member, through the vehicle, and through the openings in the second inner tubular member to engage the stop ring with the first inner member;
and
h) placing a removable locking device through a bore in the locking rod opposite the stop ring to prevent the removal of the rod from the inner tubular members.
