Description

  The present invention comprises a product display case provided with a locking device that can be locked and locked in order to prevent theft of the product due to shoplifting, and a unlocking device that releases the locking lock for the case of displaying and displaying the product in a store It relates to an anti-theft device.

  Conventionally, in various retail stores or the like, a crime prevention tag is attached to each product in order to prevent the displayed product from being stolen. Therefore, if the product is to be taken out of the store with the security tag attached, a detection device installed at the entrance gate issues an alarm to prevent theft.

  However, since the security tag is usually attached to the product with an adhesive and can be peeled off, if it is removed from the product and discarded before being taken out of the store, there is no anti-theft effect.

  For this reason, for example, products that are put in an outer case such as a paper box such as cosmetics sold at a drug store display only an empty outer case from which the product has been extracted, and customers who purchase this product are An empty exterior case is brought to a cashier counter, and a store clerk inserts a product into the exterior case.

  However, the customer is reluctant to purchase a product simply by examining an empty outer case, and usually desires to visually examine and examine the actual product.

  By the way, the problem of theft is the same in rental video shops and the like, and therefore, the present applicant has proposed a number of disc display cases. Such a disc display case is locked by the locking device so that it cannot be opened, and when the customer brings it to the checkout counter, the store clerk releases the locking device by the unlocking device and delivers it to the customer in a state where the lid can be opened. ing.

  However, in the case of a disc display case, the locking device is configured to be locked by inserting the key member into the display case, and unlocked by extracting the key member from the display case by the unlocking device. There is a problem that the key members are piled up at the checkout counter and require subsequent arrangement and management.

  When the product display case provided by the present invention is a product put in an outer case, the outer case containing the product is stored in the display case, or the product taken out from the outer case is stored in the display case. Display at the store. Alternatively, in the case of a product that does not have an exterior case, the product is displayed in a store by storing the product in a display case (hereinafter, the product stored in the product display case is simply referred to as “product” regardless of the presence or absence of the external case) ). The product display case is entirely or partially transparent, and the product can be seen through from the outside with the naked eye.

  At this time, the product display case is provided with a security tag inside. Therefore, when an unauthorized person pretending to be a customer tries to take a product display case out of the store, the detection device installed at the entrance gate issues an alarm to prevent theft.

  The product display case has an open / close structure, and the product can be taken in and out by opening the lid, but in the closed state, it is locked and locked by a locking mechanism so that it cannot be opened unless an unlocking device is used. Yes. Therefore, the customer examines the product display case by looking through the product, and if the customer wishes to purchase, bring it to the cashier counter, and the store clerk unlocks the locking mechanism with the unlocking device. Open the lid and deliver the product to the customer. The empty product display case after taking out the product is then reused in the store.

  A general merchandise store such as a drug store is generally crowded with cashier counters, which requires quick unlocking and quick delivery of goods. This is the first problem of the present invention.

  Further, in mass merchandisers and the like, there are no end to the malicious fraudsters who try to unlock the locking mechanism in order to remove products from the product display case. Since such an unauthorized person is experienced and skilled, there is a risk of unlocking the locking mechanism by inserting a jig such as a screwdriver through a slight gap.

Therefore, the locking means 11 simply locks and locks with one touch simply by fitting the first case component 4 and the second case component 7 in the X-axis direction. Since the locking part 9 of the case 1 can be easily and easily released by one touch only by facing the unlocking part 40 of the unlocking device 3, the operability is extremely high. Therefore, when the customer brings the merchandise display case 1 to the checkout counter in order to purchase the merchandise M, the store clerk uses the dedicated unlocking device 3 to open the merchandise display case 1 very quickly. In addition, since a part such as a key member that is removed from a conventional product display case is not required, it takes less time to store the product display case after opening.

  In particular, according to the present invention, the magnet unlocking locking means 11 is engaged by inserting the incorrect jig J from the gap S in a state where the first case component 4 and the second case component 7 are fitted. Permanent locking means 60 is provided to lock the locking means 11a so that it cannot be swung in the Y1 direction while the locking means 11a is locked to the locked means 11b when the locking means 11a is pushed in the Y2 direction. Therefore, when an unauthorized person attempts unauthorized unlocking by inserting the unauthorized jig J from the gap S, the permanent locking means 60 functions and makes the first case structural body 4 and the second case structural body 7 permanent each other. Lock in hell so that it is impossible to separate. Therefore, when an unauthorized person tries to take the product display case 1 out of the store, the crime prevention tag 17 detects theft. Therefore, the security effect of preventing theft is extremely high. If the permanent locking means 60 functions, the product display case 1 cannot be opened even by the unlocking device 3. Therefore, in the store, the product display case 1 is destroyed and the taken-out product M is displayed as a new product display. What is necessary is just to store in case 1 and to display again.

  The locking means 11a of the magnet unlocking type locking means 11 is constituted by a swinging piece 34 that can swing in the Y-axis direction, and is provided with a claw portion 35 that projects from the swinging piece 34 in the Y2 direction. The locked means 11b is constituted by a locking window hole 36 for receiving and locking the claw portion 35.

  Therefore, as in the present invention described in claim 2, when the rocking piece 34 is pushed in the Y2 direction by a fraudulent jig J, the rocking piece 34 cannot be rocked in the Y1 direction. A protrusion 59 for locking the swinging piece 34 and the locking window hole 36 can be provided, and the permanent locking means 60a can be constituted by the protrusion 59. In this case, when the illegitimate person inserts the unauthorized jig J from the gap S and the swing piece 34 is pushed in the Y2 direction, the permanent locking means 60a is activated by the protrusion 59 being caught, and the magnet unlocking type locking means It is permanently impossible to release the lock by 11.

  Further, as in the third aspect of the present invention, when the rocking piece 34 is pushed in the Y2 direction by the improper jig J, the rocking piece 34 is broken so that it cannot rock in the Y1 direction. The fragile hinge portion 57 to be provided is provided, and the fragile hinge portion 57 can constitute the permanent lock means 60b. In this case, when the swinging piece 34 is pushed in the Y2 direction by an unauthorized person inserting the unauthorized jig J from the gap S, the fragile hinge portion 57 is broken 63, whereby the permanent locking means 60b is activated and the magnet is disengaged. It is impossible to release the locking lock by the lock-type locking means 11 permanently.

  In this case, according to the fourth aspect of the present invention, the shielding wall 54 is provided to face the lower side of the swing piece 34, and the lower end portion of the outer wall surface facing the Y1 direction of the swing piece 34 is disposed on the shield wall. A guide surface 58 that is inclined to the Y1 direction from the lower end portion toward the upper portion is formed, and the guide means 58 constitutes the inducing means 62. Therefore, when an unauthorized person inserts the unauthorized jig J from the gap S and searches the inside while bringing the distal end of the unauthorized jig J into contact with the shielding wall 54, the distal end of the unauthorized jig J happens to be in the swing piece 34. The possibility of swinging in the Y1 direction by being caught is very low. Rather, the tip of the incorrect jig J is guided to the vicinity of the lower end of the swing piece 34 by the guide surface 58, and when the tip of the jig J is moved, the swing piece By swinging 34 in the Y2 direction, the probability of operating the permanent lock means 60 is increased.

  According to the fifth aspect of the present invention, in addition to the magnet unlocking locking means 11, the protruding piece unlocking locking means 10 is provided, and the locking mechanism 2 performs the locking by the double lock. Because of the configuration, the security effect is further improved. In other words, the protruding piece unlocking means 10 cannot be unlocked unless a pressing force in the Y2 direction is applied to the operating portion 12, and the magnetic unlocking means 11 has a pulling force in the Y1 direction by the magnet. Since the product display case 1 cannot be opened unless both the locking means 10 and 11 are unlocked at the same time, it cannot be unlocked unless it is acted. It is very difficult to open the cover illegally. And although it is the locking mechanism 2 which performs such a double lock with a high security effect, it is easy and easy by one touch only by fitting the 1st case structure 4 and the 2nd case structure 7 in the X-axis direction, Moreover, both locking means 10 and 11 can be locked and locked simultaneously. On the other hand, at the time of unlocking, the double lock can be easily and easily released by one touch by simply sliding in the Y1 direction with the product display case 1 placed on the table 39 of the unlocking device 3. Therefore, operability is extremely high.

In this state, the case main body 4a is locked and locked by the protruding piece unlocking locking means 10 so as not to separate from the bottom member 4a in the X1 direction.

  As shown in FIG. 12 (A), when the standing wall plate 16 is inserted into the insertion space 15, the magnet unlocking type locking means 11 is configured such that the guide tapered surface 35 a of the claw portion 35 is the edge of the inner wall plate 13. , The swing piece 34 is swung in the Y1 direction so that the claw portion 35 is retracted from the inner wall plate 13, and thereby the upright wall plate 16 is inserted into the fitting space 15. forgive. When the upright wall plate 16 is completely inserted into the insertion space 15, as shown in FIG. 12B, the swing piece 34 is restored to return the claw portion 35 to the original position, and the claw portion 35 The locking edge 35 b is inserted and locked into the locking window hole 36. In this state, the case main body 4a is locked and locked by the magnet unlocking locking means 11 so as not to separate from the bottom member 4a in the X1 direction.

  FIG. 13 shows the operation when the unlocking device 3 releases the locking lock state. When the bottom member 4 a is placed on the table portion 39 of the unlocking device 3 and slides in the Y1 direction, the outer wall plate 14 faces the unlocking portion 40. In order to facilitate the positioning of this facing arrangement, as shown in FIG. 1, the product display case 1 (the surface of the outer wall plate 14 in the example) and the unlocking device 3 (the upper surface of the unlocking part 40 in the example) Are displayed with alignment marks 43 and 44, respectively. In addition, for the purpose of facilitating the sliding movement and preventing the bottom surface of the bottom member 4a from being scratched by the sliding movement, small protrusions 45 are provided on the bottom surface (for example, the four corners of the bottom surface) of the bottom member 4a. Yes.

  After positioning so as to be in the above-described arrangement state, as shown in FIG. 13, when the product display case 1 is slid in the Y1 direction on the table portion 39, the projecting piece 41 faces the operating portion 12, and the magnet 42 is moved. It faces the magnetic piece 34a.

(Permanent lock action)
FIG. 14 shows the operation when an unauthorized person attempts to unlock the card. As shown in FIG. 14 (A), the protruding piece unlocking type locking means 10 has the operation piece 12 of the locking means 10a located at the opening 27 of the outer wall plate 14, so that the unauthorized person is the driver. When the operation piece 12 is pushed in by inserting such an improper jig J, the locking means 10a is moved in the Y2 direction and separated from the locked means 10b, so that the protruding piece unlocking type locking means 10 The lock lock state is released. However, even in this state, the magnet unlocking locking means 11 maintains the locking lock state, and therefore the second case component 7 cannot be moved in the X1 direction.

  Therefore, the unauthorized person who has failed to unlock then inserts the unauthorized jig J through the gap S and tries to release the locked state of the unlocking means 11 of the magnet unlocking type. As shown in FIG. 14B, when the fraudulent jig J is inserted deeply, the swing piece 34 of the locking means 11a is pushed in the Y2 direction, and the protrusion 59 enters the locking window hole 36 of the locked means 11b. By getting over, it is locked to the edge 36a of the locking window hole 36. In this state, the claw portion 35 locks the locking edge 35c in the vicinity of the protrusion 59 to the locking window hole 36, and the second case component 7 cannot be moved in the X1 direction. In this state, even if the fraudulent jig J is pulled out from the gap S, the protrusion 59 is locked to the edge 36a, so that the swing piece 34 cannot swing in the Y1 direction. Permanent locking means 60a for locking 35 to the locking window hole 36 so as not to be detached is constituted. Therefore, in the state in which the permanent locking means 60a is functioning, as shown in FIG. 15, even if the magnet 61 faces the locking portion 9, the locking locks of the locking means 11a and the locked means 11b are unlocked as soon as possible. It becomes impossible.

  As described above, in the locked lock state where the locking means 11a is locked to the locked means 11b, the shielding wall 54 is disposed on the lower side of the swing piece 34, and the swing piece 34 extends in the Y1 direction. The outer wall surface that faces is formed with a guide surface 58 that inclines in the Y1 direction at an angle θ from the lower end portion toward the upper surface with the lower end facing the outer surface of the shielding wall 54, and the guide surface 58 is standing wall It is located inside the wall thickness T of 16 (inside the window hole 53). Therefore, when an unauthorized person inserts the unauthorized jig J from the gap S and moves the tip of the unauthorized jig J while searching the inside from the state where the distal end of the unauthorized jig J is in contact with the shielding wall 54, it happens by chance. The possibility of swinging the swing piece 34 in the Y1 direction is extremely low. Rather, the leading end of the improper jig J is guided to the vicinity of the lower end of the swing piece 34 by the guide surface 58 located inside the wall thickness T of the upright wall 16, so that the end of the improper jig J is moved. As a result, the swing piece 34 is swung in the Y2 direction, and the lock of the permanent lock means 60a as described above is caused. Therefore, the guide surface 58 thus constitutes the permanent lock inducing means 62.

  Further, as shown in FIG. 14B, when the swing piece 34 is pushed in the Y2 direction by inserting the fraudulent jig J deeply as described above, the fragile hinge portion 57 is broken and the damaged portion 63 is broken. Form. In this state, the claw portion 35 locks the locking edge 35c in the vicinity of the protrusion 59 to the locking window hole 36, and the second case component 7 cannot be moved in the X1 direction. In this state, even if the incorrect jig J is pulled out from the gap S, the rocking piece 34 cannot be restored in the Y1 direction by the damaged portion 63, and thus the claw portion 35 cannot be detached from the locking window hole 36. Permanent locking means 60b for locking and locking is configured. In the state in which the permanent lock means 60b is formed in this way, as shown in FIG. 15, even when the magnet 61 faces the lock portion 9, the lock means 11a and the locked means 11b are no longer locked. It is impossible to lock.

  Although the illustrated embodiment shows a permanent locking means 60a constituted by the projection 59 of the claw part 35 and a permanent locking means 60b constituted by the damaged part 63 of the fragile hinge part 57, the permanent locking means 60 of the present invention is shown. May be constituted by only one of the permanent locking means 60a, 60b. Further, in the example shown in the figure, the protrusion 59 constituting the permanent locking means 60a is formed in a wedge shape so that the protrusion 59 can easily enter the locking window hole 36 and is not easily retracted. Further, the projection 59 can be provided on the lower edge of the locking window hole 36 in addition to the claw portion 35. In short, when the locking means 11a is pushed in the Y2 direction, the permanent lock means 60 is permanently locked so that it cannot swing in the Y1 direction while the locking means 11a is locked to the locked means 11b. What has a function should just be.

  As described above, when the permanent locking means 60 functions as a result of the fraudulent act of the unauthorized person, the first case structure 4 and the second case structure 7 cannot be separated from each other. Therefore, when an unauthorized person tries to take the product display case 1 out of the store, the crime prevention tag 17 detects theft. If the permanent locking means 60 functions, the product display case 1 cannot be opened even by the unlocking device 3. Therefore, in the store, the product display case 1 is destroyed and the taken-out product M is displayed as a new product display. It will be stored in case 1 and displayed again.

  FIG. 16 shows another embodiment in which the product display case 1 is a small case, and the protruding piece unlocking locking means 10 is the same as the above embodiment, but the magnet unlocking locking means 11 is Locking means 11 a made up of one swing piece 34 and locked means 11 b made up of one lock window hole 36 are provided. Other configurations are the same as those in the above embodiment.

  The anti-theft device of the present invention is not limited to the rectangular parallelepiped product display case 1 as shown in the illustrated embodiment, but various types of products that are displayed in a state in which the product is stored, such as a disc storage case such as a DVD or CD, and other cases.
