Abstract

A zipper lock for luggage case comprises a housing including a pair of concaves capable of receiving a pair of pull tabs of a double zipper so as to lock up the tabs therein by a pair of the first latching means and a pair of second latching means worked in cencert with the first latching means provided to lock up a binding strap which has a coupler and a locking plate at two ends made in conforming with the shape of the housing. The housing contains also a combination lock. When the combination lock is set on-combination, to unlock the pull tabs and the binding strap only press a mannual push button inwardly to the housing. The binding strap can bind additional luggage cases or handbags and lock them together with parent luggage case.

Claims

1. A zipper lock attached to a luggage case capable of locking sliders of a double zipper and a binding strap comprising:

a zipper lock having a housing and means for closing said housing;

said housing comprising a cam rectangular opening at a center of an arcuate slopped portion, a pair of windows symmetrically arranged at two corners adjacent said rectangular opening, a pair of concaves partitioned by a projection at a center of a flat portion opposite to said arcuate slopped portion thereof and a pair of first latching slots symmetrically formed through an upper wall thereof adjacent said concaves;

a pair of first cylinder posts, a pair of second cylinder posts and a pair of pivots spacedly projected downward at their predetermined positions from the inner surface of said upper wall;

means for attaching said zipper lock onto said luggage case projected downward from predetermined positions inside said housing;

an enclosed U-shaped bulk head surrounding said projection and said concaves having a pair of lateral portions of said U-shaped bulk head connected to an inner wall of said flat portion thereof each having a second latching slot therethrough in communication with said concaves, a transverse portion connected to one end of said projection having a first spring seat on a center thereof, said projection having a concave on an inner side, a transverse abutment connecting the lateral portions of said U-shaped bulk head and the other end of said projection having means for fastening said means for closing said housing projected downward from an under side thereof;

a pair of second spring seats respectively formed abutting an inner surface of side walls thereof;

projecting means for fastening said means for closing said housing at four corners inside said housing;

two sets of positioning means spacedly projected downward from inner surface of said upper wall thereof positioned symmetrically relative to said U-shaped bulk head and adjacent said second spring seats;

a pair of triangular side walls abutting said opening and bridged by a second transverse abutment on the bottom of which has a pair of protrudent means centrally projected downward and a recess on an inward side between said protrudent means;

a push button slidingly disposed into said opening, said push button having a stem projected downward from a bottom thereof and engageable into said recess of said second transverse abutment, a pair of retaining means projected outward from fore corners and stopped against an inward edge of said triangular side walls, a wedged portion projected inward from the middle of fore end between said retaining means and a rectangular recess centrally formed at the fore end thereof beneath said wedge portion;

an actuating means slidingly disposed into said housing beneath said push button, said means having a rectangular flat portion received into said rectangular recess of said push button, a hollow wedged portion capable of enclosing said wedged portion of said push button, an aperture centrally formed through a bottom, a third spring seat centrally formed at a fore end made in registry with said first spring seat and biased by a first spring means therebetween and a support stem projected upward from a top thereof;

a pair of first latching pivoted means each having a sleeve pivoted onto said first posts in symmetrical manner, a latch towards said second latching slots extended outward from a periphery of said sleeve and a lever extended outward from an opposite periphery of said sleeve and intersecting each other with their intersection stopped against the support stem of said actuating means and the wedged portion therebetween;

a pair of coupling means each having a sleeve pivoted onto said second posts in symmetrical manner, a first extension extended from a periphery of said sleeve having a perpendicular portion stopped into the aperture of said actuating means therein and a second extension extended from an opposite periphery of said sleeve having a hook at free end thereof engageable with a recess of a combination lock which has a pair of dials pivoted onto said pair of pivots inside said housing and biased by a pair of second spring means and accessible from outside of said pair of windows;

a pair of second latching means slidingly disposed into said housing between said first latching means and said second spring seats and limited by said positioning means, said second latching means each having a hollow rectangular body, a beveled latch which is made in registry with said first latching slots at an upper portion thereof and a fourth spring seat at an outward end for biasing a third spring means with said second spring seat therebetween;

a spring plate for ejecting the pull tabs of said double zipper secured to said means for fastening said housing and said means for closing said housing therebetween, said spring plate having a U-shaped body, a pair of screw holes through a transverse portion of said U-shaped body made in registry with said fastening means and a pair of lateral portions inserted through said concaves;

said means for closing said housing having a first flat body conforming with the bottom of said housing and a plurality of screw holes adjacent four corners made in registry with said projecting means for mounting said means for closing said housing onto said housing by means of fasteners;

a binding strap capable of locking into said first latching slots of said zipper lock, said strap comprising a strap, a coupling means crossing bound into said strap, a locking means bound to one end of said strap and a buckle bound to the other end of said strap and through the body thereof;
