Description

  The present invention relates to a merchandise display case that can be locked and locked to prevent theft of merchandise due to shoplifting when displaying and displaying merchandise in a store, and an unlocking device that releases the locking lock.

  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.

That is, the disc portion 31 is inserted into the opening 3 by passing the lid-opening claw 9 g through the notch 34. At this time, the rotation preventing claw 9i comes into contact with the lower surface of the opening edge 3a at a position removed from the recess 36, and is elastically contacted against the elasticity of the leaf spring 9h.

  When the bottom member 2 and the case body 5 are rotated in the circumferential direction of the opening 3 from this state, as shown in FIG. 12A, as soon as the rotation prevention claw 9i faces the recess 36, the leaf spring It is inserted into the recess 36 by 9h elasticity (elastic urging means). Thereby, the bottom member 2 and the case main body 5 are locked so as not to be rotatable relative to each other.

  When the rotation prevention claw 9i is fitted into the recess 36, the positions of the lid opening prevention claw 9g and the lid opening prevention locked portion 10e are set so that the lid opening prevention claw 9g overlaps the upper surface of the tongue piece 35. Yes. Accordingly, as shown in FIG. 12 (B), when the lid opening prevention claw 9g overlaps the tongue piece 35, the bottom member 2 and the case body 5 are locked so as not to be separated.

  In order to unlock the locked state by the locking mechanism 6, an unlocking device 50 as shown in FIG. 10 is used. The unlocking device 50 includes a support body 14 that supports the convex portion 33 of the bottom member 2 so that the convex portion 33 can be placed thereon, and a magnet 15 that faces the both ends of the convex portion 33 in the supported state from below. In the case of the illustrated example, the support 14 is erected on the seat plate 37, and the magnet 15 is embedded in the support 14.

  The support 14 is provided with a holding portion 38 that sandwiches both side surfaces of the convex portion 33 in a state where the convex portion 33 is placed. Therefore, when the case body 5 is rotated in the circumferential direction of the opening 3 with the convex portion 33 placed on the support body 14, the bottom member 2 is held by the holding portion 38 so as not to follow and rotate. The Such a holding portion 38 can be constituted by a protrusion and a small hole that are locked to each other in addition to the holding piece as shown in the figure. In short, the bottom member 2 is placed on the support 14. What is necessary is just to prevent the bottom member 2 from rotating in a state.

  Therefore, when the bottom member 2 (the projecting portion 33 in the illustrated embodiment) is placed on the support 14, the rotation preventing claw 9i is attracted to the magnet 15 as shown in FIGS. Retreats against the 9h elasticity (ballistic urging means) and leaves the recess 36. Thereby, the non-rotatable locked state of the bottom member 2 and the case body 5 is released.

  Subsequently, when the case body 5 is rotated in the circumferential direction of the opening 3, as shown in FIGS. 13C and 13D, the tongue piece 35 is detached from the opening prevention claw 9g, and the stopper 34a is opened by the opening prevention claw 9g. Abuts the side of As a result, the notch 34 faces the lid opening preventing claw 9g, and the unlocking impossible state of the bottom member 2 and the case main body 5 is released. Therefore, as shown in FIG. Can be separated upward. In the case of the illustrated example, since a pair of notches 34 are provided on both sides of the tongue piece 35, the lid cannot be opened even if the case body 5 is rotated in either the clockwise or counterclockwise direction. There is an advantage that can be canceled.

  During the opening operation, the bottom member 2 is fixed on the support 14 by attracting the leaf spring 9h to the magnet 15, so that the bottom member 2 follows when the case body 5 is separated upward. The product display case 1 can be preferably opened without floating.

  In this way, the product display case 1 can be opened almost simultaneously with the operation of placing the bottom member 2 on the support 14 and rotating the case body 5, and the product M is opened by the opening, Immediately, the product M on the bottom member 2 can be picked up.
