BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to a dial lock slides for a slide fastener of a bag, a trunk, etc., and, especially, to one for a slide fastener so manufactured as to prevent theft by enabling the carrier to alter the dial code at will.
The locking device of prior arts is so made, as is seen in FIG. 7, that a slide 91 on one side and another slide 92 on the other side are slid toward each other, a pair of rows of elements (not shown in the drawing) are joined and a handle 93 connected with the lug 92a of said slide 92 on one side is turned, while a lever 93a is kept pressed down, so that a lug 91a of said slide 91 may be inserted in a lock groove 93b of said handle 93, and said lever 93a is released, whereupon said handle 93 and said slide 91 are joined by means of a lock member 93c, and this state a key cylinder 93d of said handle 93 is turned by a key to fix said lock member 93c.
But in a locking device for a slide fastener of prior arts it is found pretty easy to open the lock by the use of a key not quite fitting the key cylinder 93d, and thus the practicability of such a locking device is quite insignificant, and, for a serious disadvantage, it is impossible to apply such a device for of prior arts to a slide fastener with more than three slides.
SUMMARY OF THE INVENTION
The present invention is, therefore, intended to supplement these shortcomings and provide a dial lock slide for slide fastener, which allows of alteration of the dial code at will to prevent an easy opening access of the lock.
With a view to achieve the above objectives the present invention is characterized by its specific construction, wherein a lock bar, which has a number of keys projected in a line on both sides of the outer surface, is provided at the end the lug of a slide; a cylinder, which has guide slits open on both sides so as to admit of the insertion of said keys above in them, is provided at the end of the lug of the slide on the other side; a number of locking devices, which are made by insertion of a lock ring with inner key grooves in a dial ring in a way that it can be fitted or removed at will, are provided so that said cylinder can be inserted in them as a whole keeping them rotatable at all times; and the end of said cylinder is inserted in a coupling ring intended for prevention of said locking devices from falling off.
By this construction, after rotating said locking devices so that slits on both sides of said cylinder and said inner key ring grooves may be joined together said lock bar is inserted in said cylinder, and when said locking devices are turned to certain degrees the slides on both sides will catch to lock.
Below, the present invention is described in further detail, references being made to the attached drawings as are required:

DETAILED DESCRIPTION OF THE INVENTION
FIG. one is a perspective view to show the present invention, which shows the slides 1, 2 on both sides positioned facing each other, which join a pair of rows of elements 3 together or separate them from each other by their sliding. The dial lock of the present invention comprises generally a male slide 1 and a female slide 2 which engage one another and are locked together by rotatable locking devices.
