Description

  The present invention relates to a theft prevention case for preventing a recording medium product made of an information recording medium from being illegally taken out from a store or a rental store.

  Conventionally, in order to prevent recording medium products such as CDs, DVDs, and game software from being illegally taken out from dealers or rental stores, the recording medium products are stored in a transparent case body for display, A variety of anti-theft cases are provided with locking means having locking pieces that lock out recording media products from the edge of the opening on the front side of the case body. (For example, refer to Patent Documents 1 to 3.)

  These anti-theft cases are such that when the recording medium product is stored and displayed in the store, the locking piece of the locking means protrudes to the opening side and locks the product so that the product cannot be taken out. The product can be taken out by releasing the means and retracting the locking piece out of the opening. However, due to the recent thinning of recording medium products, if the protruding length of the locking piece is short, the recording medium product can be forcibly taken out by forcibly bending the recording medium product. In addition, if the protruding length of the locking piece increases, the strength cannot be maintained, and the protruding end side of the locking piece can be held by hand and pulled to the front side, etc. It becomes possible to take out.

  Therefore, in view of the above-mentioned situation, the present invention intends to solve the problem that even if the locking piece of the locking means is forcibly damaged in order to illegally take out the stored recording medium product, the product is taken out. It is in the point of providing an anti-theft case that can prevent this.

In order to solve the above-mentioned problems, the present invention provides a case main body having an opening on the front side through which a recording medium product made of an information recording medium is taken in and out, and a recording medium that protrudes from the edge of the opening toward the opening. In the anti-theft case provided with a locking means having a locking piece that locks the product so that it cannot be taken out, the protruding end side to the opening is partially separated from the locking piece of the locking means, so that the remaining part A fracture guide groove is provided along a substantially gusseted fracture assumption line where a plurality of peaks with sharp tips are arranged, and the tip position of one or more peaks formed after the fracture separation is separated. The fracture assumed line is defined so as to substantially coincide with the position of the protruding end edge of the previous locking piece, the fracture guide groove is formed along this line, and the protruding end of the locking piece is longer than the expected fracture line. the thickness of the separation portion side, and configured to be thinner than the proximal end side That was constructed anti-theft case (claim 1).

  Here, it is preferable that the fracture guide grooves along the assumed fracture line are provided intermittently at appropriate intervals (claim 2).

  Moreover, it is preferable that the said fracture | rupture guide groove is a penetration groove penetrated in the front-back direction of the said locking piece (Claim 3).

In addition, a pair of left and right fracture guide grooves that gradually approach the projecting edge are provided, both of which are grooves up to the front of the projecting edge, and the intersection on the extension line of these grooves is substantially at the position of the projecting edge. with matching grooves, which mountain the tip positioned between the pair of grooves substantially coincide with the position of the projecting edge is formed after fracture separation is preferable (claim 4).

  According to the anti-theft case according to the invention of the present application as described above, the locking piece of the locking means has a substantially serrated break so that the protruding end side is partly separated and a plurality of peaks with a sharp tip are lined up in the remaining part. Since the breaking guide groove is provided along the assumed line, even if the stored recording medium product is forcibly taken out, the locking piece breaks from the root part even if the locking piece is forcibly twisted.・ Before breakage, bending or breaking separation occurs along the assumed fracture line, and the product is locked by a plurality of sharp peaks remaining on the proximal end side of the locking piece to prevent removal. Can do.

  That is, it is possible to avoid that the product can be taken out because the locking piece breaks from the base even if there is fraud, and the product is locked with a plurality of peaks with sharp tips appearing on the protruding end side The effective lock function can be maintained. In addition, since each mountain has a pointed shape, it is difficult to bend or break each mountain further, and at the same time, if any further damage is made, the finger is injured at the tip of each mountain. An effect (intimidation effect) is produced, and cheating can be praised.

  In addition, the rupture assumption line is determined such that the tip position of one or more peaks among the plurality of peaks formed after the break separation substantially coincides with the position of the protruding edge of the locking piece before the separation. Since the breaking guide groove is formed along the edge, the position of the tip of one or more ridges substantially coincides with the position of the protruding edge, and the locking piece maintains the same original protruding length after separation as before separation. In addition, it is possible to maintain the original function that cannot be taken out even if the product or the like is bent forcibly, and the large pile can be expected to have a sufficient restraining effect.

  Further, since the break guide grooves along the assumed fracture line are provided intermittently at appropriate intervals, there is no inconvenience that the strength of the locking piece is significantly reduced due to the presence of the break guide grooves, It is also possible to avoid unexpected situations such as damage other than the original fraud, for example, when a store clerk manages product replacement.

  Further, since the breaking guide groove is a through groove penetrating in the front-rear direction of the locking piece, when the protruding end of the locking piece is forcibly squeezed, the breaking guide groove is smoothly bent along the through groove. Breakage separation can occur.

  In addition, since the thickness of the separation part on the protruding end side of the locking piece is assumed to be thinner than the base end side, when forcing the protruding end of the locking piece, for example, The separation portion having a low strength is bent or broken first, so that almost no force acts on the base portion of the locking piece, and the bending or breaking separation can be smoothly performed along the breaking guide groove.

  In addition, a pair of left and right fracture guide grooves that gradually approach the projecting edge are provided, both of which are grooves up to the front of the projecting edge, and the intersection on the extension line of these grooves is substantially at the position of the projecting edge. By forming the matching grooves, a crest in which the tip position substantially coincides with the position of the projecting edge is formed between the pair of grooves after breaking and breaking. It is possible to reliably form a large mountain that maintains the same initial protruding length as before separation, and to more reliably exert a product locking function and a check function against fraudsters.

  Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

  As shown in FIG. 1, the anti-theft case 1 of the present invention comprises a case main body 10 having an opening 10a on the front side for receiving and inserting a recording medium product 9 made of an information recording medium, and an edge 12 of the opening 10a. And locking means 11 having a locking piece 20 that locks the recording medium product 9 that appears and retracts on the opening side so that it cannot be taken out.

  The stored recording medium product 9 can be widely applied to a recording medium on which a program is recorded and an information recording medium such as a CD, a DVD, a Bluray Disc (registered trademark), a game software, and a video tape. Then, the product locked by the locking means 11 or the recording medium product may be stored together with an anti-theft tag, an anti-theft buzzer, an anti-removal cover and the like so that they are integrally locked so that they cannot be taken out. .

  As shown in FIG. 2, the case main body 10 is a square-shaped box body that is open at the front, and has a rectangular rear plate 40 that contacts the back surface of the recording medium product 9, and an outer peripheral edge of the rear plate 40. A box composed of upper and lower plates 41 and 44 and left and right plates 42 and 43 extending from the front side to the front side is integrally formed with a transparent synthetic resin (other materials may be used), and is formed on the front side. The recording medium product 9 can be taken in and out through the opening 10a.

  At the front end of the lower plate 44, a locking plate 45 for locking the lower front surface of the stored recording medium product 9 is formed in a predetermined length upward. The product 9 cannot be taken out by locking the upper portion with the lock means 11 in a state where the is locked. In this example, the locking plate 45 is provided on the left and right over the entire length of the lower plate 44, but may be partially provided on a part of the lower plate 44, for example, at the center, or between the lower plate 44 and the left plate 42. A locking plate may be provided at each of the corners of the upper and lower plates 44 and the right plate 43. In this example, since the locking means 11 is provided on the upper plate 41 of the case body 10 as will be described later, the locking plate 45 is provided on the lower plate 44 opposite to the locking plate 11. Needless to say, it may be provided in the same manner on the plate opposed to this.

  The rear plate 40 is provided with a through hole 40a for inserting a finger from the back side to push out the recording medium product 9 to the front opening 10a side. The case body 10 is preferably configured to be transparent so that the back side of the recording medium product can be easily seen. However, the case body 10 may be configured to be translucent, low in transparency, or non-transparent.

  As shown in FIGS. 2 and 3A, the upper plate 41 of the case body 10 is provided with a lock means 11 including the locking piece 20 that protrudes and appears on the opening side. Specifically, the locking means 11 includes a locking member 2 that is integrally formed with a locking piece 20 as a closing portion for closing a part (upper right corner) of the opening 10a and slides left and right, It is provided on the upper surface side of the upper plate 41 and slides and guides the locking member 2 to the left and right and holds it at a position where the locking member 2 moves to the opening side (position where the locking piece 20 locks the product). It comprises a slide guide portion 26 having engagement means (not shown).

  The locking means 11 may be any means as long as the locking piece 20 protrudes and retracts toward the opening side to prevent the recording medium product 9 from being taken out from the case body 10, and the locking member 2 slides to the left and right as in this example. In addition to those that move and the locking piece 20 appears and disappears, for example, as shown in FIG. 3 (b), the locking member 2 is inserted / attached from above the upper plate 41 or moved up and down. Various forms can be employed, such as one in which the locking piece 20 appears and disappears, and one in which the locking member 2 rotates and moves around the central axis 22 as shown in FIG. . Further, the recording medium product 9 may be in direct contact with the recording medium product 9, or the recording medium product 9 may be indirectly engaged with the cover if the product 9 has a removal prevention cover or the like on the front surface. You may stop. Further, the locking means 11 may be provided on the left and right plates 42 and 43 in addition to those provided on the upper plate 41.

  As shown in FIGS. 4 and 5, the locking piece 20 of the locking member 2 is provided with a fracture guide groove 3 along a substantially jagged fracture assumption line 30, and the recording medium product 9 inside is provided. Even if the protruding end edge 20a of the locking piece 20 is forcibly removed to be taken out illegally, the locking piece 20 is bent or separated along the fracture assumption line 30 before the locking piece 20 breaks or breaks from the root portion. A plurality of peaks 21, 21 </ b> A with sharp tips are lined up in the remaining portions that are generated and separated. In addition, in FIG. 4A, the approximate serrated fracture line 30 is indicated by the upper or lower edge of the fracture guide groove 3 and an imaginary line indicated by a one-dot chain line in the drawing.

  The plurality of sharp peaks 21, 21 </ b> A appearing on the protruding edge 20 a side maintain an effective lock function capable of similarly locking the recording medium product 9. In addition, since each of the peaks 21 and 21A has a pointed shape, it is difficult to bend or break it further, and a restraining effect such as injury to the finger is produced, and further illegal acts can be praised. effective. In this example, a groove 31 that is bent in a substantially inverted N shape in order from the left side, a groove 32 that is bent in a substantially M shape, and a groove 33 that is bent in a substantially N shape are predetermined along the assumed fracture line 30. They are connected at intervals.

  In this example, the fracture guide grooves 3 (31 to 33) are through-grooves penetrating in the front-rear direction of the locking piece, but may be non-penetrating grooves (bottomed grooves). Further, in this example, the separation portion 23 on the projecting edge 20a side of the assumed fracture line 30 is made thinner than the proximal end side, and the separation portion 23 having a lower strength first bends or breaks, Almost no force is applied to the base portion of the stop piece 20 and the bend or break separation occurs smoothly along the assumed fracture line 30. However, the entire stop piece 20 does not have such a thin wall. Of course, the thickness may be set to a uniform thickness. In this example, since the fracture guide groove 3 is a through-groove, although the separation portion 23 is thin, bending or fracture occurs along the groove, but the fracture guide groove 3 is as described above. In the case of the non-penetrating groove, it is configured to be thinner than the thin separation portion 23 and to be bent or broken along the groove.

  As shown in FIG. 4A, the interval between the grooves 31 and 32 is such that the intersection point on the extension line of the pair of left and right groove portions 31b and 32a that gradually approach each other toward the protruding edge 20a is located at the position of the protruding edge 20a. It is set to approximately match. As a result, a relatively large crest 21A is formed between the pair of groove portions 31b and 32a after breaking and separation, as shown in FIG. 4B, with the tip position substantially coinciding with the position of the protruding edge 20a. The same applies to the interval between the grooves 32 and 33, and the intersection point on the extension line of the groove portions 32b and 33a that gradually approach each other toward the protruding end edge 20a is set so as to substantially coincide with the position of the protruding end edge 20a. After separation, a relatively large peak 21A is formed between the pair of groove portions 31b and 32a, the tip position of which substantially coincides with the position of the protruding edge 20a.

  The mountain 21 formed by the other portions of the grooves 31, 32, 33 is a small mountain compared to the large mountain 21A described above. The large mountain 21A maintains the same initial protruding length as before separation, and can more reliably exert the function of locking the product and the function of checking against the fraudster.

  The groove shape of the present invention is not particularly limited as long as the large mountain 21A is formed as described above. For example, as shown in FIGS. A groove 31 that is bent in a substantially inverted N-shape and a groove 33 that is bent in a substantially N-shape may be connected in series at a predetermined interval. Here, as shown in FIG. 7A, the interval between the grooves 31 and 33 is an intersection point on the extension line of the groove portions 31b and 33a that gradually approach each other toward the protruding end edge 20a, at the position of the protruding end edge 20a. It is set so as to substantially match, and after breaking and separation, as shown in FIG. 7 (b), the tip position between the pair of grooves 31b and 33a is substantially large so as to substantially match the position of the protruding edge 20a. A mountain 21A is formed.

  As another example, for example, as shown in FIGS. 8A and 8B, a plurality of grooves 32 and 32 bent in a substantially M shape along the assumed fracture line 30 are provided at a predetermined interval. It may be a thing. Again, as shown in FIG. 8 (a), the distance between the grooves 32, 32 is such that the intersection on the extension line of the grooves 32b, 32a that gradually approach each other toward the protruding edge 20a is at the position of the protruding edge 20a. After breaking and separating, a relatively large peak 21A is formed between the pair of grooves 32b and 32a, the tip position of which substantially matches the position of the protruding edge 20a, as shown in FIG. 8 (b). It is formed.

FIG. 9 shows a modified example in which a plurality of grooves 34 bent in a substantially inverted V shape are continuously provided at a predetermined interval along the fracture assumption line 30. Similarly to the above, the interval between the grooves 34 and 34 is set so that the intersection point on the extension line of the groove portions 34b and 34a that gradually approach each other toward the projecting edge 20a substantially coincides with the position of the projecting edge 20a. After breaking and separating, as shown in FIG. 9B, a relatively large peak 21A is formed between the pair of grooves 34b and 34a, the tip position of which substantially coincides with the position of the protruding edge 20a.

  In the present invention, the valley between the peaks 21, 21 </ b> A formed on the locking piece 20 after breaking and separation may be curved and curved. FIG. 10 is an example in which the assumed fracture line 30 is set in a substantially jagged shape in which the valley portion is curved and bent in this way, and in this example, it is bent in the substantially inverted N shape illustrated in FIGS. The groove 31 and the groove 33 bent in a substantially N shape are respectively deformed and formed. Similar to the example shown in FIGS. 6 and 7, the gap between the grooves 31 and 33 and the relatively large crest 21 </ b> A formed after breakage separation. Thus, by making the valley part into a curved shape, the visual image becomes gradual, which is preferable in terms of design.

  FIG. 11A is a modified example of the present invention in which straight grooves 35 are continuously provided along the assumed fracture line 30 at intervals, and the grooves 35 and 35 gradually approach each other toward the projecting edge 20a. Among the sets, at least some of the sets (35A, 35A) are set so that the intersection point on the extension line substantially coincides with the position of the projecting end edge 20a, and a large peak is formed between them after breakage separation. It is configured. FIG. 11B shows a plurality of short grooves 36 arranged at intervals. Similarly, in a row of predetermined grooves 36A that gradually approach each other toward the projecting edge 20a, the intersection on the extension line projects. It is set so as to substantially coincide with the position of the edge 20a, and is configured such that a large peak is formed after breakage separation.

The locking piece 20 before breaking and separation is not limited to a square shape as in this example, but may be other shapes such as a curved tip or a triangular shape. In addition, as shown in FIG. 11 (c), it is also a preferred embodiment to form a concavo-convex shape portion 24 continuous with the protruding end edge 20a. In this case, it is more preferable that among the plurality of convex portions forming the concavo-convex shape portion 24, the predetermined convex portion 25 constitutes the tip portion of the relatively large mountain 21A described above. That is, in the case of the groove shape of FIG. 11A, for example, the extended line of the grooves 35A, 35A forms a substantially V-shaped convex portion 25 that substantially matches the contour, and the tip of the groove 35A is at the time of breaking. The outline of the convex portion 25 is reached, and a large mountain having the convex portion 25 at the tip is smoothly formed. That is, the fracture length is shortened compared to the case where such a convex portion 25 or the concave-convex shape portion 24 does not exist, and a large mountain having the tip shape as expected by the convex portion 25 can be reliably formed.

  Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and can of course be implemented in various forms without departing from the gist of the present invention.
