Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a lock that is attached to a zipper for opening and closing clothing pockets, various bags, handbags, and the like.

[Conventional technology]

It is well known that fasteners are so convenient that they cannot be compared to buttons, and that they are now very widely used. However, the advantage of fasteners being easy and quick to open and close has the disadvantage that anyone can easily open someone else's fasteners, leading to theft of valuables. This is simply because the fastener's lock has no security and is completely defenseless.

In fact, the reality is that fasteners are not equipped with a complete locking mechanism.

[Problem that the invention attempts to solve]

The present invention solves the above-mentioned drawbacks without changing the structure of conventional fasteners. That is, a mechanism is provided in which a lock that allows the locking rod to move up and down is fastened to the edge of the opening of a handbag or the like to which a fastener is sewn, and when the lock is engaged, the locking rod protrudes upward to block the passage of the fastener slide. This prevents someone else from accidentally opening the fastener, and adds safety to the convenience of the fastener to prevent valuables from being stolen.

[Means for solving problems, examples]

The present invention will be explained below based on the illustrated embodiments.

Fig. 1 is an exploded perspective view of the present invention, Fig. 2 is a front view showing the internal structure with the locking rod unlocked, and Fig. 3 is a front view showing the locking rod in the locked state. FIG. 4 is an explanatory diagram showing a state in which a lock is fastened to one side of the fastener of the handbag.

Grooves 2 and 2' into which a locking rod 3 is inserted are formed on one side of a body 1 with a back plate 1'. Locking rod 3
One end of the spring 4 is inserted into the support rod 4' which protrudes inside the body 1, and the other end is inserted into the step 3 of the locking rod 3. to return the locking rod 3 downward.Body 1
A locking plate 5 with a groove 5' cut therein is horizontally elastically installed by a spring 6 so that it can be engaged with the middle part of the locking rod 3, and the front side of the locking plate 5, that is, the lid An operating plate 7 having a bent portion 7' on the left side and a protrusion 7'' formed on the upper right side is attached to the inside of the plate 8, and the knob 7 of the operating plate 7 is inserted into the center hole 8' of the cover plate 8. A key hole 9 formed inside the center lower side of the body 1 communicates between the operating plate 7 and the latch plate 5, and a key hole 9 is formed in the lower center of the body 1 so that the key hole 9 can be moved left and right by grasping the knob 7 with the hand. 1
0 is inserted, the protrusion 10' protruding from the central back of the key 10 engages with the groove 5' of the locking plate 5, and both sides of the key 10 are connected to the bent portion 7' of the operation plate 7 and the protrusion 7''. The operating plate 7 and the locking plate 5 are inserted between them and are indirectly engaged with each other via the key 10. Therefore, when the operating plate 7 is moved from side to side with the knob 7, the locking plate 5 is interlocked with the locking plate 5. The lock is unlocked by pulling it out or inserting it into the groove 3' of the rod 3. Also, the concave groove 10'' of the key 10 allows the key 10 to be inserted into the hole 9.
When the key 10 is unlocked by inserting it into the key 10, the groove 10'' of the key 10 engages with the protrusion 1'' protruding from the inner surface of the body 1.
Prevent a fall of 0. The cover plate 8 is fastened to the screw holes 13, 13' by screws 14 and nuts 14'. Of course, when attaching the body 1 to one side of the fastener 11 of a handbag or the like, the inner side 12 connects the contact plate 1' and the body 1, and they are fastened together by extension of the screws 14. That is, as shown in FIG. 4, the attachment position of the lock is appropriately determined so that the locking rod 3 of the lock blocks the passage of the slide 12 of the fastener 11.

[Function and effect of the idea]

Attach a lock to the place where you want to lock the fastener of a bag, handbag, etc. as shown in Figure 4. It is only necessary to attach it in such a way that the passage of the slide 12 is immediately blocked when the locking rod 3 is raised. However, in order to prevent the slide 12 from forcibly moving around the locking rod 3 by folding the hem cloth of the fastener backwards, a contact plate 1' is fastened to the inside of the fastener so as to fit snugly with the body 1. Since the fastener 11 is attached to the contact plate 1', the slide 12 cannot be tricked.

When the lock is unlocked, the locking rod 3 is connected to the spring 4.
The passage of the slide 12 of the fastener 11 is opened and the slide 1 can be moved freely.
2, the fastener 11 can be opened and closed as desired. However, when the locking rod 3 is pushed upward to lock the lock, the locking plate 5 moves to the right by the elasticity of the spring 6 and engages with the locking groove 3'' of the locking rod 3, thereby locking the locking rod 3. Then Slide 1 of Fastner 11
The passage No. 2 is blocked, making lateral movement of the slide impossible, resulting in the fastener 11 being indirectly locked and unable to be opened.

When unlocking, insert the key 10 into the hole 9. However, the key 10, which is not unlocked by the operation of inserting the key 10, serves to engage the locking plate 5 and the operation plate 7, so when the key 10 is inserted into the hole 9, the protrusion 10' is engaged with the groove 5' of the locking plate 5. Furthermore, since the key 10 is inserted between the bent portion 7' and the protrusion 7'' of the operation plate 7, when the knob 7 is grasped by hand and moved laterally, the key 10 is pressed in cooperation with the operation plate 7.
0, and as the key 10 moves laterally, the locking plate 5
moves laterally while pressing the spring 6, and at the moment when the end of the locking plate 5 comes out from the locking groove 3'', the locking rod 3, which has been locked until now, is unlocked downward by the elasticity of the spring 4. When unlocking, the concave groove 10'' of the key 10 engages with the protrusion 1'' protruding from the inner surface of the body 1, so it will not fall or come off.This lock is for a fastener, so the fastener will It can be applied to any sewn item, and has the effect of further increasing the convenience of fasteners and the safety of opening them.
