Japanese Patent No. 3459997

  By the way, as shown in FIGS. 10 and 11 of the attached details, the lock device for preventing the removal of the opening prevention lock plate of the lending case shipped from the manufacturer of the structure of Patent Document 1 includes a case main body 101 constituting the case K, and The lock plate L is inserted into the insertion space from the side surface opening 103 of the lid 102 that closes the case main body 101, and is engaged with each other as the insertion is performed to lock the closure.

  At this time, the plurality of locking portions 104 provided on the lock plate L are in a locking relationship with the engagement portions 105 provided in the case K, and the customer is prevented from removing the lock plate L. Keep closed.

  And the locking relationship of the latching | locking part 104 with respect to the above-mentioned engaging part 105 is unlocked using the shop side unlocking tool, and the lock board L is pulled out.

  When the synthetic resin lock plate L is molded, the locking portion 104 is provided at the tip of the rocking bodies 107 and 108 that extend from the thin hinge portion 106 and extend in opposite directions (front and rear in the drawing). One end of the intermediate oscillating body 110 that is supported by the support shaft 109 overlaps the upper surface of the locking portion 104 of one oscillating body 107, and the other end of the intermediate oscillating body 110 is directly above the locking portion 104 of the other oscillating body 108. Incorporated to be located.

  When the iron pieces 111, 112, 113 provided on the respective rocking bodies 107, 108 and the intermediate rocking body 110 are magnetically absorbed by the magnet of the shop-side unlocking device, the rocking bodies 107 are swung in the upward direction. The locking relationship between the locking portion 104 and the engaging portion 105 is lost, and the locking relationship between the locking portion 104 and the engaging portion 105 is lost as the swinging body 108 swings in the upward direction.

  On the other hand, the intermediate rocking body 110 having the iron piece 112 makes the end of the intermediate rocking body 110 abut on the locking portion 104 of the rocking body 108 when the rocking angle due to magnetic absorption increases.

  Then, since the locking relationship between the locking portion 104 and the engaging portion 105 of the rocking body 108 cannot be released, the lock plate L cannot be pulled out.

  That is, it is considered that the lock plate L can be removed when the swing angle of the intermediate swing body 110 accompanying the magnetic absorption of the iron piece 112 is small.

  According to the lock structure as described above, if there is a slight deviation in the position of the fulcrum of the intermediate oscillating body, there has been a problem that smooth unlocking operation cannot be performed and assembly is troublesome.

  Of course, there was also a problem that careful attention was required for the position where the iron piece was fixed to the intermediate rocking body.

  In particular, if the direction of both ends of the intermediate rocking body during installation is changed, it may cause malfunction. That is, it becomes a defective product, and since the intermediate rocking body is assembled in a narrow space on both sides of the lock plate, the assembling work is difficult. In addition, the iron pieces 111, 112, and 113 are attached to the rocking bodies 107, 108, and 110, and the lower edges of the iron pieces 111, 112, and 113 are fitted into the recessed portions provided on the upper surfaces of the rocking bodies 107, 108, and 110, respectively. Since it is driven in while applying a hammer to the upper edge after insertion (adhesive is applied and applied to the fitting portion as necessary), it takes a lot of time and greatly increases the cost.

  Accordingly, the present invention is to provide a lock device that can be easily assembled.

  In order to solve the above-described problems, the present invention is a type in which the opening of the case is prevented by the engagement relationship between the insertion member to be inserted into the insertion path of the case and the box and lid constituting the case. In the display case of the type in which the opening on the entire surface of the case is closed by the stopper of the insertion member to be inserted into the insertion path of the case, a second tilting body connected to the end of the first tilting body via a connecting plate that is elastically deformed is provided. The end of the first tilting body and the tip of the second tilting body on the connecting plate side are pivotally attached to the side surface of the insertion member via pins, respectively, and the end of the second tilting body, the insertion path, When the insertion of the insertion member is completed, the push-back is released and the engagement relationship is provided on one side, the engagement portion is provided on the other side, and the iron piece is provided on the tip and end of the first tilting body. .

  Then, the first tilting body and the second tilting body that are connected to the insertion member via the connecting plate via the pin are attached to be freely tiltable, so that the lock device can be assembled very easily.

  As described above, according to the locking device of the present invention, the second tilting body having the locking claw or the engaging portion that is in the locking relationship via the connecting plate that is elastically deformed to the first tilting body is coupled, Since the middle of the first tilting body and the tip of the second tilting body are pivotally attached to the side surface of the insertion member via pins, the assembling work of the lock device to the insertion member becomes extremely easy.

  Further, by using the magnet of the unlocking tool on the shop side to magnetically absorb the iron piece at the tip of the first tilting body, the end of the second tilting body is raised via the connecting plate, and the locking claw and the engaging portion Can be smoothly released.

  In addition, since the locking claw elastically deforms the connecting plate and gets over the engaging portion as the insertion member is inserted, the insertion member can be smoothly inserted.

  In addition, since the iron piece is provided at the end of the first tilting body, when unlocking by a customer other than the shop is performed by using a magnet, the second iron via the coupling plate is absorbed by the magnetic absorption of the iron piece at the end of the first tilting body. Remove the end of the tilting body.

  For this reason, the engagement relationship between the locking claw and the engaging portion is maintained, and there is an effect that the unlocking cannot be performed.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  In the embodiment of the present invention, the opening of the case K is prevented by the engagement relationship between the box 1 and the lid 2 constituting the case K by the insertion member B inserted into the insertion path A of the case K in FIGS. A display case of the type (which prevents the removal of rental products such as videotape, game software, manga, etc., and sales products, which is not limited to the product X stored in the case K by opening prevention, the illustrated disc) FIG. 9, the opening 4 on the entire surface of the case K ′ is closed by the stopper 3 on the opposite side of the insertion direction of the insertion member B to be inserted into the insertion path A of the case K ′. The present invention relates to a display case of a type that prevents the removal of a storage case that stores a disc.

  As a method of preventing the opening of the case K by the insertion member B of the case K, in the case of illustration (similar to the drawing of Japanese Patent No. 3459997), the outside and inside of the box body 1 and the lid body 2 of the case K An insertion port 6 is provided by cutting from the upper edge of one side of the peripheral walls 5, 5 to the middle of the lower side, and the insertion member A is inserted into the insertion port 6.

  Then, a 7-shaped locking protrusion 7 on the inner surface of the peripheral wall 5 on the upper side of the box 1 (in the illustrated case, it protrudes from a part of the peripheral wall 5 but may protrude from a necessary part such as the full length). The upper edge of one side wall B ′ of the insertion member B is fitted into a locking relationship, and the distal end portion of the insertion member 16 protrudes in the insertion direction of the insertion member B into the cylindrical portion 8 on the inner surface of the lid 2. In addition to preventing the case K from being opened, and the U-shaped notch in the vicinity of the insertion opening 6 of the peripheral walls 5 and 5 that overlap the upper and lower sides of the case 1 and the lid 2 of the case K. 9 and 9 are fitted with a horn 10 projecting upward from the upper surface of the distal end opposite to the insertion direction of the insertion member B, and the end side of the insertion member B is not prevented by the locking relationship accompanying the insertion. The holding piece 11 protruding from the edge circumscribes (holds) the box body 1 and further prevents the opening. It is, but not limited, there may be formed of the insertion member other structure comprising the engaging relationship between the open blocking that pivot hinge 12 of the box body 1 and the lid 2 by the insertion of the B.

  Further, as an exhibition case K ′ other than the above, as shown in FIGS. 8 and 9 (for example, Japanese Patent Application No. 2003-290900), an opening 4 around the case K ′ is formed with an upper side wall 13 of the case K ′, The insertion member B is inserted into the insertion path A formed in the direction opposite to the opening 4 from the opening 4 with the partition wall 14 on the lower side (back side) of the upper side wall 13, and the insertion member B is inserted in the insertion direction. By closing a part of the opening 4 with the stopper 3 at the end, the product X stored in the case K ′ is prevented from being extracted.

  Next, as a component of the locking device, the tip of the second tilting body 23 is connected to the end of the first tilting body 21 via a connecting plate 22 that is elastically deformed.

  The first tilting body 21 and the second tilting body 22 that are connected via the connecting plate 22 are integrally formed of synthetic resin in the case of illustration, but are not limited, and are thin elastic deformation such as a leaf spring or synthetic resin. The first tilting body 21 and the second tilting body 23 may be connected (connected) to both ends of the connecting plate 22 to be connected.

  Then, the end portion (midway) of the first tilting body 21 and the tip end portion of the second tilting body 23 are attached to the side surface of the insertion member B via pins 24 and 25, respectively.

  In the above-described attachment, if the attachment portion on one side surface of the insertion member B is opened by the stealing portion 26 as shown in the drawing, the attachment operation becomes extremely easy. However, the presence or absence of the stealing unit 26 is not limited.

  Although the through hole 27 of the pin 24 is formed into a long hole in accordance with the tilting of the first tilting body 21, the tilting is smoothly transmitted to the second tilting body 23 by the deformation tilting of the connecting plate 22, but is not limited. The tilting may be transmitted to the second tilting body 23 by the deformation of the connecting plate 22. Of course, the pivotable attachment by the pins 24 and 25 is also replaced with the penetrating method of the pins 24 and 25, and pins (not shown) protruding from the side surfaces of the first tilting body 21 and the second tilting body 23 are attached to the insertion member B. You may support so that rotation is possible.

  Then, the end of the second tilting body 23 and the insertion path A (on both opposing surfaces) are pushed back as the insertion member B is inserted, and are locked to one side when the insertion of the insertion member B ends. The claw 29 is provided with an engaging portion 30 on the other side.

  In the illustrated example, the engaging portion 30 is provided in a continuous sawtooth shape, but is not limited thereto, and may be a protrusion or the like.

  As shown in the figure, when the insertion member B is molded, a tilting body 32 is integrally provided via a thin connecting portion 31, and the tilting body 32 and the insertion path A (opposing surface) have the same relationship as described above. Although the pawl 33 and the engaging portion 34 are provided, they are not limited and may not be provided as necessary, that is, to complicate the unlocking method.

  Furthermore, iron pieces 41 and 42 are provided on the top surfaces of the tip and end of the tilting body 21.
