The link arm is composed of a plurality of elements flexibly joined to each other by cylindrical joints, joined to the bicycle or vehicle by a perpendicularly oriented central hinge, allowing for restricted movement and rotation of other elements in the link arm. The link arm is designed to, when fastened, form a closed loop around the bicycle or vehicle frame, wheel and bike rack. When not in use, the device can be folded into a neat, compact configuration for convenient storage. The central perpendicular hinge enables fast and simple transition between the two states of fastened and in storage.

In combination: an over-the-road vehicle with a frame bounding a cargo space and at least one door having inside and outside surfaces and a peripheral edge; and a first locking assembly connected to the vehicle. The first locking assembly extends in an inside to outside direction over at least a portion of the thickness dimension of the peripheral door edge and so that a first portion extends to beyond the outside door surface. The first portion of the first locking assembly is configured to be engaged by a locking device that acts between the first locking assembly and another component to maintain the first door in the closed position. The first locking assembly is configured so that a region of the first portion is locally strengthened in a manner to resist severance and/or bending.

A door lock with a reinforced fireproof effect includes a lock body mounted on a door and inner and outer operating units mounted to two sides of the door, respectively. The lock body includes inner and outer chassis made of ferrous material or stainless steel having a melting point higher than 1300° C. Inner and outer fixing members coupled with the inner and outer chassis are also made of ferrous material or stainless steel. Thus, these components of the door lock are less likely to melt during a fire, reducing the spreading speed of the fire.
