(Configuration of opening and closing locking device)
As shown in FIG. 1 to FIG. 3, an exhibition case 2 as an exterior case for storing a product 1 such as a soft storage case is almost entirely open so that the product 1 can be removably received in the storage chamber 3. A dish-shaped case body 5 having an opening 4 is formed, and located on two opposite sides of the opening 4, a stopper wall 6 is provided on one side, and an opening / closing locking device 7 is provided on the other side. ing.

  The opening / closing locking device 7 is inserted into the housing 8 so as to be movable in the insertion direction F1 and the drawing direction R1 with respect to the X axis direction along the housing 8 extending along the opening edge of the case body 5. The key member 9 is attached to the housing 8 so as to be movable forward and backward in the forward direction F2 and the backward direction R2 with respect to the opening 4 with respect to the Y-axis direction from the opening edge of the case body 5 toward the opening 4. The lock member 10 is constituted. The housing 8 is integrally formed with the case body 5 together with the stopper wall 6 from a synthetic resin, and the key member 9 and the lock member 10 are separately formed from the synthetic resin.

  Therefore, when the locking member 10 is moved in the backward direction R2 by operating the opening and closing locking device 7 as described later, the product 1 gets over the stopper wall 6 and enters the storage chamber 3 via the opening 4. It can be accommodated in a substantially fitted shape, or can be removed from the accommodated state through the opening 4. When the lock member 10 is moved in the forward direction F2 in a state in which the product 1 is stored in the storage chamber 3, the lock member 10 closes a part of the opening 4 and thereby the product 1 is opposed to the stopper wall 6 facing each other. Since it is restrained by the lock member 10, the product 1 cannot be taken out from the storage chamber 3.

  The housing 8 includes a back wall 11 that stands up substantially in the same plane as the back wall 5 a of the case body 5, and an upper wall 12 that extends from the standing end of the back wall 11 and faces the peripheral wall 5 b of the case body 5 in the Z-axis direction. A groove 13 is formed. The groove portion 13 has a groove opening 14 that opens along the opening edge of the opening portion 4, and an entrance / exit 15 that opens at an end portion in the X-axis direction, and is connected to the groove opening 14 so as to protrude in the Y-axis direction. A piece 16 is provided. The other end of the groove 13 in the X-axis direction is closed by the end wall 17.

  The locking member 10 includes a vertical plate portion 18 that covers the groove opening 14 of the groove portion 13, and a horizontal plate portion 19 that extends from the vertical plate portion 18 toward the inside of the groove opening 14. A connection hole 20 into which the connection piece 16 is inserted is formed. Therefore, the locking member 10 is incorporated in the groove portion 13 so as not to fall off due to the locking of the connecting piece 16 and the connecting hole 20, 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 member 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 28 extends along the X-axis direction at the edge of the horizontal plate portion 19 of the lock member 10, and a lock claw 27 is biased to the end of the notch 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.

  The elastic biasing means 50 is configured by a V-shaped spring member formed integrally with the key member 9, and the inner surface 17 a of the end wall 17 of the housing 8 in a state where the key member 9 is inserted into the housing 8. And the repulsive force caused by this is caused to generate a frictional force at the engaging portion between the tip end of the lock claw 27 and the end portion of the notch portion 28, and the engagement of the locking means 25. Maintain a good stop state. That is, in the state where the key member 9 is urged in the pulling direction R1 by the elastic urging means 50, the tip end portion of the lock claw 27 is similarly urged toward the pulling direction R1, so that it faces the pulling direction R1. The front end of the lock claw 27 is locked in a pressed state with respect to the bottom of the notch 28 that faces. In the illustrated embodiment, the elastic urging means 50 is illustrated as being provided at the end of the key member 9, but may be provided on the inner surface side of the housing end wall 17. It may be provided between the end walls 17.

  The bottom of the notch 28 forms a recess 28a facing the drawing direction R1, whereas the tip of the lock claw 27 forms a protrusion 27a that fits into the recess 28a. In the case of the illustrated example, the recess 28a is formed so as to have an acute angle portion where the upper portion of the locking end portion of the cutout portion 28 protrudes from the bottom portion, and the convex portion 27a of the lock claw 27 is formed with the acute angle portion 28a. Although it is tapered so as to be joined, in short, in a shape in which the protrusion 27a is fitted in the recess 28a, and the lock claw 27 is prevented from swinging in the direction of releasing the locked state. It only has to be configured. Therefore, when the key member 9 is urged by the elastic urging means 50 in a state where it is inserted into the housing 8, the projection 27 a at the tip of the lock claw 27 is fitted in the recess 28 a of the notch 28. It becomes. Thereby, the locked state of the lock claw 27 and the notch 28 is stabilized, and the lock of the lock means 25 is prevented from being released even when vibration or the like occurs.

  Then, when unlocking the locking means 25, the key member 9 may be slightly pushed in the insertion direction F1. As a result, the tip end portion of the lock claw 27 that has been pressed against the notch portion 28 by being biased by the elastic biasing means 50 loosens the pressing engagement state. In the case of the illustrated embodiment, the convex portion 27a of the lock claw 27 is retracted from the concave portion 28a of the notch 28, and the lock can be released.

  Further, the lock member 10 and the key member 9 move the lock member 10 in the forward direction F2 when the key member 9 is moved in the insertion direction F1, and the lock member 10 when the key member 9 is moved in the pull-out direction R1.

Two support walls 42 are integrally provided.

  The base wall 40 faces the lock member 10 so as to face the backward direction R <b> 2 of the lock member 10, and forms a receiving groove 43 extending in parallel with the first support wall 41.

  The first support wall 41 is provided with unlocking magnet means 44 so as to be exposed on the inner wall surface, and the second support wall 42 is provided with extraction magnet means 45 so as to be exposed on the inner wall surface, A protruding portion 55 is provided at a position where it comes into contact with the plug portion 23. 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 member 10 in the forward direction F2 by pressing the horizontal plate portion 19 of the locking member 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 member 10 can be moved in the backward direction R2 in conjunction with the movement.

  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 pulling-out direction R1, the arm-shaped main driving means 32 of the opening interlock cam mechanism 30 is slid while engaging with the driven means 33, so that the locking member 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 lock member 10 can be moved in the backward direction R <b> 2, and the key member 9 is prevented from being pulled out from the entrance 15 and falling off. . In this manner, the lock member 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 portion 4 is opened by retracting the vertical plate portion 18 from the opening portion 4 of the case body 5. Therefore, the product 1 can be taken out from the storage chamber 3.

  After unlocking, when the product 1 is stored in the storage chamber 3 of the case body 5 and then locked again by the opening / closing locking device 7, the key member 9 is simply moved in the insertion direction F <b> 1 from the pulled-out position, and the plug portion 23. Need only be inserted into the doorway 15. For example, when the operator pushes the key member 9 in the insertion direction F1 with a fingertip or the like, the cam surface 38 of the projection 37 in the closing interlock cam mechanism 31 presses against the edge of the hole 36 in the insertion direction F1, The edge of the hole 36 moves in the Y-axis direction along the cam surface 38, moves the lock member 10 in the forward direction F <b> 2, and closes a part of the opening 4 of the case body 5 by the vertical plate 18. After the projection 37 is removed from the hole 36 by the movement in the insertion direction F1, the projection 37 is supported by the horizontal plate portion 19 of the lock member 10 and fixes the lock member 10 so as not to move in the backward direction R2.
