Abstract

An exemplary shackle is configured for use with a crossbar having a pair of openings and a locking mechanism including a pair of deadbolts. The shackle includes a substantially flat plate portion having a length in a longitudinal direction, a width in a transverse direction, and a thickness along a lateral axis defining a proximal direction and a distal direction. The length is greater than the width, which is greater than the thickness. The shackle further includes a pair of longitudinally-offset legs extending distally from the plate portion. Each leg has a diameter, and includes a bumper and a notch positioned distally of the bumper. An offset distance is defined between the distal surface of the plate portion and the distal faces of the bumpers. The width of the plate portion is greater than each of the diameter and the offset distance.

Dependent claims

A lock, comprising:

a shackle comprising:
a plate portion having a length in a longitudinal direction, a thickness in a lateral direction, and a first width in a transverse direction, wherein the length is greater than the first width, and wherein the first width is greater than the thickness;
and
a pair of longitudinally-offset legs extending from the plate portion in the lateral direction, wherein the legs are fixedly and immovably secured to the plate portion, and wherein the plate portion prevents relative movement of the legs;
wherein each leg of the pair of longitudinally-offset legs includes a corresponding and respective foot, and wherein each foot includes a corresponding and respective notch;
and
a crossbar comprising:
a pair of longitudinally offset openings, wherein each foot is received in a corresponding and respective one of the openings;
a pair of deadbolts, wherein each deadbolt is in an extended position in which the deadbolt is engaged with the notch of a corresponding and respective foot;
and
a locking mechanism configured to selectively retain the deadbolts in the extended positions thereof, thereby selectively securing the shackle to the crossbar;
wherein the plate portion is offset from the crossbar by an offset distance such that a portion of each leg is exposed, and wherein an exposed portion of each leg has a diameter;
wherein the first width of the plate portion is greater than the offset distance;
and
wherein the first width of the plate portion is greater than the diameter of the exposed portion of each leg.

and
a foot extending downward from the second portion, the foot including a notch, wherein the foot is configured to be received in a corresponding one of the pair of openings, and wherein the notch is configured to engage the locking mechanism to secure the shackle to the crossbar;
wherein the legs are permanently and immovably secured to the plate portion such that the plate portion prevents relative movement of the legs;
wherein the lower surface of the plate portion is laterally offset from the lower face of the bumper by an offset distance;
and
wherein the first width is greater than each of the diameter and the offset distance.
