Abstract

A simple tumbler-type lock is incorporated in a housing having entrance and exit slots for receiving one end of a strap. The other end of the strap is secured to the housing so that the strap may be looped around a piece of luggage and passed through the slots into the housing. The lock itself serves to anchor the strap within the housing when in locked condition. Unlocking of the lock, in turn, releases the strap so that it may be pulled from the housing to enable opening of the luggage.

Claims

1. A luggage strap lock comprising, in combination:

a. a housing having entrance and exit slots at opposite ends;

b. a woven strap having one end secured to said housing at a point beneath the slots and its other end adapted to encircle a piece of luggage and be passed through said entrance slot into the housing and out the exit slot to define a loop;

c. a lock in said housing having an exposed keyway for receiving a key, said lock being of the tumbler type including a cylinder which operates by rotation of said cylinder in response to insertion and rotation of the correctly fitting key, said cylinder including an off-center projection which is moved from a lower diametric position to an upper diametric position upon operation of the lock; and

, d. securing means in said housing responsive to operation of said lock to move from a first position in which the portion of said strap in the housing between said entrance and exit slots is engaged in a manner preventing backward movement of the strap out of said entrance slot, to a second position in which said strap is released in a manner so that it can be moved out of said entrance slot, said securing means including a cam member pivoted in the housing for rotation about an axis at right angles to the axis of said cylinder, said cam member having a forward portion overlying said projection and an under surface engaging said strap in said housing when said projection is in its lower diametric position; and

a spring biasing said cam member in a rotational directio to hold its under surface in engagement with said strap, movement of said projection to its upper diametric position by operation of said lock serving to rotate said cam member about its pivot axis in a direction against the bias of said spring in such a manner that its under surface is raised to release said strap.
