Become. Therefore, the lock member 10 is unlocked by moving the key member 9 in the pull-out direction R1, so that the product can be taken out from the display case and delivered to the customer.

  Therefore, the present invention is configured so that when the key member 9 is inserted into the housing 8, the lock means 25 automatically holds and locks the key member 9 from the direction intersecting the pull-out direction R1. Rather, an elastic biasing means 50 is provided to apply a pressing locking force to the locking means 25 by biasing the key member 9 in the pulling-out direction R1 at the retaining locking position. Accordingly, an unauthorized customer attempts to unlock the magnet by appropriately facing the magnet from the outside of the housing 8, and even if the magnet is accidentally exposed from the direction of releasing the locking of the locking means 25, Unless the suction force is sufficient to release the pressing locking force, there is an effect that the locking effect is high because the risk of the unlocking locking of the locking means 25 being easily unlocked is low.

  On the contrary, when unlocking the locking means 10, if the key member 9 is moved in the insertion direction F <b> 1 against the elastic urging means 50 from the retaining locking position, the pressing urging force applied to the locking means 25. Therefore, when the unlocking magnet means 44 is made to face the lock means 25 from a predetermined direction in this state, the locking engagement of the lock means 25 is easily released, and the key member 9 can be moved in the pull-out direction R1. . Accordingly, the unlocking device 39 can easily release the locking means 25 by simply moving the key member 9 in the insertion direction F1, so that the key member 9 can be moved in the pull-out direction R1. Unlocking is possible.

  With regard to this unlocking, according to the present invention, the unlocking magnet means 44 of the unlocking device 39 is made to face the lock means 25 from the outside of the case body 5 to release the lock and lock of the lock means 25. However, by subsequently moving the case body 5 in a predetermined direction, there is an effect that the lock member 10 can be unlocked by automatically moving the key member 9 in the drawing direction R1. Therefore, the operator does not need a complicated work of picking the key member 9 with the fingertip and moving the key member 9 in the drawing direction R1. That is, the operator places the case body 5 at a predetermined position of the unlocking device 39, pushes the case body 5 in a direction opposite to the elastic biasing means 50 as described above, and then turns the case body in the opposite direction. The key member 9 can be moved in the pull-out direction R1 only by performing a series of operations of moving the main body 5, and the lock means 10 can be unlocked with a simple operation.

  In order to enable the unlocking operation by such a simple operation, the key member 9 of the present invention has a plug portion 23 formed at the end portion in the pull-out direction R1, and a pull-out magnetic body 24 is provided on the plug portion 23. ing. Correspondingly, the unlocking device 39 of the present invention has a case in which the locking means 25 faces the unlocking magnet means 44 in addition to the first support wall 41 provided with the unlocking magnet means 44. In a state where the main body 5 is positioned with respect to the unlocking device 39, a second support wall 42 is formed on the unlocking device 39 so as to face the pulling magnetic body 24 of the plug portion 23, and the second support A drawing magnet means 45 is provided on the wall 42. Accordingly, when the operator faces the side surface of the case body 5 corresponding to the locking means 25 to the first support wall 41 in order to unlock the locking means 10, the pulling magnetic body 24 of the plug portion 23 is in that state. The extraction magnet means 45 of the second support wall 42 is exposed. Therefore, if the operator pushes the case body 5 toward the second support wall 42, the pressing locking force by the elastic biasing means 50 is released and at the same time the retaining locking of the locking means 25 is released. Therefore, if the case body 5 is moved as it is along the first support wall 41 in the direction opposite to the pushing direction, the plug portion 23 is moved through the suction of the extraction magnet means 45 and the extraction magnetic body 24. Since the second support wall 42 is fixed, the key member 9 is moved from the housing 8 in the drawing direction R1.

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

Therefore, by locking the connecting piece 16 and the connecting hole 20, the locking means 10 is incorporated in the groove portion 13 so as not to drop off, and is movable in the Y-axis direction.

  The key member 9 includes a vertical wall portion 21 facing the vertical plate portion 18 and a horizontal wall portion 22 facing the horizontal plate portion 19 when the key member 9 is inserted into the groove portion 13 from the entrance / exit 15 of the housing 8. The plug portion 23 is inserted so as to be substantially flush with the edge portion of the entrance / exit 15 in a state of moving in the insertion direction F1 with respect to the inner wall of the plug portion 23. A magnetic body 24 is provided.

  Further, the key member 9 is provided with a lock means 25 that is locked so as to prevent the movement in the pull-out direction R1 in a state where it is inserted into the housing 8, and is unlocked to be described later from the outside of the back wall 11 of the housing 8. An unlocking magnetic body 26 such as an iron plate piece for releasing the locking of the lock means 25 when the magnet means is faced is provided. Further, the lock member 9 is urged in the pull-out direction R1 in a state where the key member 9 is inserted into the housing 8 at the end opposite to the plug portion 23 with respect to the X-axis direction of the key member 9. The elastic urging means 50 for maintaining the 25 locked state is provided.

  The locking means 25 may be provided between the key member 9 and the inner wall portion of the housing 8, but in the illustrated embodiment, the edge portion of the vertical wall portion 21 of the key member 9 and the horizontal plate portion 19 of the locking means 10. Is provided between each other. In other words, a lock claw 27 is provided on the vertical wall portion 21 of the key member 9 through a notch and is elastically biased toward the inside perpendicular to the X-axis direction and has a distal end portion (27a) in the drawing direction R1. On the other hand, a notch portion 28 extends along the X-axis direction at the edge of the horizontal plate portion 19 of the locking means 10, and a lock claw 27 is biased to the end portion of the notch portion 28. A structure for locking the front end portion is formed. Therefore, when the key member 9 is moved in the insertion direction F1 and the plug portion 23 is inserted into the entrance / exit 15, the distal end portion 27a of the lock claw 27 is immersed in the bottom portion of the notch portion 28, and the distal end portion is the end of the notch portion 28. By engaging with the portion, the key member 9 is prevented from moving in the pull-out direction R1. In other words, the stopper is locked.

However, although the protrusion 55 is provided on the second support wall 42 in the illustrated embodiment, it may be provided on the plug portion 23 where the second support wall 42 faces.

(Function)
A method of using the unlocking device 39 will be described with reference to FIG. 4B, and the operation of the opening / closing locking device 7 during unlocking will be described with reference to FIG.

  3A and 3B show a state in which the key member 9 is moved in the insertion direction F1 and the plug portion 23 is inserted into the entrance / exit 15. In this state, the projection 37 of the closing interlock cam mechanism 31 is detached from the hole 36, and the projection 37 moves the locking means 10 in the forward direction F2 by pressing the horizontal plate portion 19 of the locking means 10. . The elastic biasing means 50 contacts the inner surface 17a of the end wall 17 and biases the key member 9 in the pull-out direction R1, and the convex portion 27a of the lock claw 27 of the locking means 25 is the concave portion 28a of the notch portion 28. The key member 9 is prevented from moving in the pull-out direction R1 while preventing the locked state between the lock claw 27 and the notch 28 from being released.

  When the store employee uses the unlocking device 39 and unlocks the opening / closing locking device 7 from the locked state to take out the product 1 from the display case 2, as shown in FIG. In the state where the case body 5 is held so that the opening and closing locking device 7 faces downward, the back wall 11 of the housing 8 is placed along the first support wall 41, and the protrusion 55 of the second support wall 42 is a plug portion. 23, the opening / closing locking device 7 faces the unlocking device 39 as shown by the arrow DN, and the case body 5 is moved slightly along the first support wall 41 as shown by the arrow PS from that state. When the projection 55 is pushed slightly into the key member 9 and then the case body 5 is moved along the first support wall 41 as shown by the arrow SD, the unlocking magnet means 44 and the unlocking means 44 are unlocked. The key member through the adsorption of the magnetic body 26 The lock means 25 is automatically unlocked, and the stopper portion 23 is fixed to the second support wall 45 through the adsorption of the extraction magnet means 45 and the extraction magnetic body 24 constituting the extraction auxiliary means. The key member 9 can be moved in the pull-out direction R1 and the lock means 10 can be moved in the retracted direction R2 in conjunction therewith.

  That is, when the unlocking magnet means 44 faces the back wall 11 of the housing 8 and the key member 9 is slightly pushed in the insertion direction F1, the tip end portion (the convex portion 27a) of the lock claw 27 is the locking portion of the notch portion 28. In this state, the unlocking magnetic body 26 of the locking means 25 receives the attractive force, so that the lock claw 27 resists the elastic biasing force as shown in FIG. And the tip of the lock claw 27 is detached from the notch 28. Accordingly, the key member 9 is movable in the drawing direction R1.

  As described above, since the drawing magnetic member 24 of the plug portion 23 constitutes a drawing auxiliary means that is attracted to the drawing magnet means 45, when the case main body 5 is moved, it is shown in FIGS. Thus, the key member 9 and the housing 8 move relative to each other, that is, the key member 9 moves relative to the housing 8 in the pull-out direction R1. When the key member 9 moves in the pull-out direction R1, the arm-like main driving means 32 of the opening interlock cam mechanism 30 is slid while being engaged with the driven means 33, so that the locking means 10 is moved in the backward direction R2. . At this time, since the projection 37 of the closing interlock cam mechanism 31 slides into the hole 36, the locking means 10 can be moved in the backward direction R2, and the key member 9 is prevented from being pulled out from the entrance 15 and falling off. . In this way, the locking means 10 is moved in the backward direction R2 in conjunction with the movement of the key member 9 in the pull-out direction R1, and the opening 4 is opened by retracting the vertical plate portion 18 from the opening 4 of the case body 5.
