Description

  The present invention relates to a zipper lock, and more particularly, to a zipper lock that can be used as a TSA lock integrally formed with a slider puller.

  Conventionally, a zipper lock for locking a zipper (fastener) slider pull has been used for a travel bag or the like. As a zipper lock, there are a type in which the slider puller is fixed to the bag body, and a padlock type in which two pullers are combined. In addition, there are some that can be unlocked with a TSA key for baggage inspection at airports. The following are some examples of the prior art related to zipper tablets.

  The “fastener lock” disclosed in Patent Document 1 can easily and reliably lock the slider of the slide fastener provided in the opening of the bag. As shown in FIG. 7, the slider handle plate and the lock are integrally formed. Insert the head of the slider on the locked side into the slot in the handle plate. Push the hook plate with your finger and insert the tip of the hook plate into the hole in the head of the inserted slider. When the head portion of the locked slider is locked by the handle plate of the locking slider, the sliding plate engages with the protrusion on the back surface of the hook plate to latch the hook plate.

  When the key is inserted into the keyhole and turned, the sliding plate stops moving and is locked. When the key is inserted into the keyhole and turned in the opposite direction, the sliding plate will move, and when the knob on the sliding plate is pulled with a finger, the latch will be released, the hook plate will return, and the head of the slider on the locked side will return. The lock is released. Since the lock is constructed integrally with the slider handle plate, handling is extremely convenient and easy to operate, and there is no risk of losing the lock. Since two sliders are used, it can be locked at any position. Since the handle is locked after engaging the handle plate with the slider on the locked side, there is no gap between the two sliders, and the two sliders can be brought close to each other and firmly connected. The whole is compact and has a good appearance, and can be used for small bags. Since the structure is simple, it can be mass-produced at low cost.

  The “zip lock” disclosed in Patent Document 2 can be unlocked with a TSA key, and can be securely locked even if it is downsized. As shown in FIG. 8, the annular portion of the zipper puller is locked by the slide claw at the locking restraint portion of the zipper lock. When the number lock is locked, the lock bolt is lowered, stopping the movement of the stopper and preventing the slide claw from moving. When the number lock is unlocked, the lock bolt is raised and the slide claw can slide without being blocked by the lock bolt, so that the zipper puller can be released from the slide claw by turning the knob. When unlocked with the TSA key, the movable regulator moves backward and the stopper moves backward. Since the slide claw can slide, you can turn the knob to release the zipper puller from the slide claw.

The tumbler 10 is an engaging member that matches the key of the cylinder lock. The retaining tumbler 11 is a member for holding the cylinder lock on the back plate. The tumbler spring 12 is a spring that presses the tumbler. The locking window 13 is a hole for inserting and locking the slider head. The display window 14 is a window for displaying a locked state and an unlocked state. The connecting hole 15 is a hole for connecting the zipper lock to the hole at the head of the slider.

  The operating arm 16 is a portion that is engaged with the movable arm of the cylinder lock and moved to a position corresponding to the locked state and the unlocked state. The lock arm 17 is a portion for entering the space between the leaf spring and the side wall of the main body when locked to prevent the lock ball from moving. The display arm 18 is a portion on which a lock sign indicating a locked state and an unlock sign indicating an unlocked state are drawn. The handle 19 is a part for pinching and operating a zipper lock.

  The function and operation of the zipper lock in the embodiment of the present invention configured as described above will be described. First, an overview of the function of the zipper lock will be described with reference to FIG. The connecting hole 15 on the back plate of the zipper lock is connected to the head of the first slider of the zipper. The main body 1 is attached to the back plate 2 to form a zipper lock that also serves as a slider puller. When the head of the second slider of the zipper is inserted into the locking window 13 and pushed in, the two slider balls 7 pressed inward by the leaf spring 6 sandwich the head of the second slider temporarily. Fasten. When it is not necessary to lock, the zipper lock does not shake and can be released at any time if it is in a temporarily fixed state, so that the zipper can be opened and closed with a simple operation.

  When a key is inserted into the cylinder lock 4 attached to the back plate 2 and turned, the movable arm of the cylinder lock 4 rotates and the operating arm 16 of the kanuki 3 is connected to the movable arm, so that the kanuki 3 slides. As a result, the lock arm 17 enters between the leaf spring 6 and the side wall of the main body 1 and the two locking balls 7 do not move outward, so that the head of the second slider is locked. If the master key of the cylinder lock 4 is a TSA key, it can be unlocked with a TSA key even if it is locked with an individual key. The cylinder lock 4 is protected by an outer cylinder. Since the zipper lock also serves as a puller, it can be locked and unlocked at any position.

  Next, a zipper lock that is also used as a puller will be described with reference to FIG. The connecting hole 15 at the end of the back plate 2 is connected to the hole at the head of the slider and used as a slider puller. A handle 19 is provided on the side where the cylinder lock 4 is located, and it is operated with a finger when inserting the slider head into the temporary fastening state or pulling out the slider head from the temporary fastening state. Easy to use.

  Holding the zipper lock that is also used as a puller attached to one slider of the zipper, the head of the other slider is inserted into the lock window 13 of the unlocked zipper lock. Since the locking slider has a hole in the head of the other slider, when a little force is applied, the head is sandwiched between the locking balls 7 and temporarily locked. When the cylinder lock 4 is locked in the temporarily fixed state, the locked state is reached and the head cannot be detached from the zipper lock. When the cylinder lock 4 is unlocked in the locked state, the zipper lock is unlocked and returns to the temporarily fixed state. When a little force is applied to the zipper lock to pull it up, the head is detached from the locking ball 7 and is opened.

  Next, the cylinder lock will be described with reference to FIG. The cylinder lock 4 is basically the same as the conventional one. If the tumbler 10 is pushed by the tumbler spring 12 and the tumbler 10 moves according to the key notch, the cylinder can be rotated if the key pattern matches the notch pattern or the master key. The key of the cylinder lock 4 is the same as a normal one. If the master key is a TSA key, it can be used as a TSA lock. When the cylinder rotates, the movable arm rotates and the kanuki connected to the movable arm slides. Although the movable arm is not shown, it is the same as a crank-shaped arm portion in a normal cylinder lock. A cylinder is fixed to the back plate 2 by a retaining tumbler 11. Since the cylinder lock 4 is made small for incorporation into the slider puller, the mechanical strength is not so great. Therefore, if the tumbler 10 is received by the resin main body 1 when it is intentionally unlocked, the mechanical strength is weak and it cannot be tolerated. Increased security to improve security.

  Next, display of the locked state and the unlocked state will be described with reference to FIG. On the display arm 18 of the cannuki 3, an unlocking sign and a locking sign are drawn. A display window 14 is open on the upper side of the main body 1, and when the kanuki 3 is in the unlocked state, the unlocking sign comes to the position of the display window 14. Further, when the kanuki 3 is in the locked state, the locking sign comes to the position of the display window 14. Since the lock sign and the unlock sign appear in the display window according to the movement of the cannuki 3, the locked state and the unlocked state can be visually confirmed. As shown in the A-A cross-sectional view, the cannula 3 is stably held in the locked position and the unlocked position by the holding ball 8 pressed by the holding spring 9. Further, as shown in the C-C cross-sectional view, the back plate 2 is screwed to the main body 1.

  Next, the unlocked state and the locked state will be described with reference to FIG. In the unlocked state shown in FIG. 5 (a), the cylinder lock 4 is in the unlocked position, and the movable arm of the cylinder lock 4 is also in the unlocked position. It is in the unlocked position. The locking ball 7 is pressed inward by the leaf spring 6 and is in a state where it can move outward when a force is applied. The cannula 3 is pushed in the direction of the back plate 2 by the holding spring 9 through the holding ball 8 and is stably held in the unlocked position. The unlocking sign on the display arm 18 of the cannuki 3 is at the position of the display window 14, and it can be visually confirmed through the display window 14 that it is unlocked. If it is in the unlocked state, the head of the slider can be inserted into the locking window 13 to be in a temporarily fastened state.

  In the locked state shown in FIG. 5 (b), the cylinder lock 4 comes to the locked position, and the movable arm of the cylinder lock 4 also comes to the locked position, so that the kanuki 3 connected to the movable arm also slides to the left in the figure. Then come to the locked position. The lock arm 17 of the cannula 3 enters between the leaf spring 6 and the side wall of the main body 1, and the locking ball 7 is stopped so as not to move outward. The locking ball 7 is pressed inward by the leaf spring 6 and is not movable outward even when a force is applied. The cannula 3 is pushed in the direction of the back plate 2 by the holding spring 9 through the holding ball 8 and is stably held in the locked position. The lock sign on the display arm 18 of the cannuki 3 is at the position of the display window 14, and it can be visually confirmed through the display window 14 that it is locked. When the locked state is changed from the temporarily fixed state, the slider head cannot be removed from the locking window 13, and the zipper cannot be opened. If the slider head is not inserted into the locking window 13 and the slider head is inserted into the locking window 13, the locking ball 7 does not move. Can not.

  Next, the operation procedure and operation will be described with reference to FIG. FIG. 6 schematically shows a cross section passing through the center of the locking ball 7. In the unlocked state (a), the locking ball 7 is pushed inward by being pushed by the leaf spring 6, but it can move outward. In the state (b) immediately before the slider head is inserted into the locking window 13, the locking ball 7 remains the same as in the unlocked state. In the state (c) in the middle of insertion, the locking ball 7 is pushed outward by the head and moves outward. When the head is further inserted and the locking ball 7 enters the hole in the head, a temporary fastening state (d) is obtained. In this state, the head can be removed with a little force. When the cylinder lock 4 is locked in this state, the cannula 3 enters between the leaf spring 6 and the side wall of the main body 1 so that the locking ball 7 cannot move outward. Therefore, the head cannot be pulled out. When unlocking, the cylinder lock 4 may be unlocked and the head removed in the reverse procedure.

  As described above, in the embodiment of the present invention, the zipper lock is connected to the head of the first slider of the zipper by connecting the connecting hole of the back plate, and also serves as a puller by the lock body part attached to the back plate, With two locking balls pressed inward by leaf springs, temporarily hold the head of the second slider of the zipper, and when the cylinder lock is locked, the cannula slides and locks the ball. Since it is configured to lock by not moving, a small TSA lock can be operated easily.

  The zipper lock of the present invention is most suitable as a TSA zipper lock for travel bags. It is also suitable as a zipper lock for collection and delivery bags.
