  FIG. 6 shows an enlarged configuration of the case lock 6. FIG. 6A shows a state viewed from above, and FIG. 6B shows a state viewed from the front. As shown in FIG. 6, the case lock 6 includes a lock body 31 and a lock receiver 32, and locks by locking between the lock body 31 and the lock receiver 32.

  The lock body 31 is an electric type that uses a solenoid 33 that is a pull-type DC solenoid as a drive source for unlocking and locking, and includes a lock plunger 34. The lock plunger 34 is configured by assembling a latch receiver 36 to the plunger 35 of the solenoid 33, and is urged in a protruding direction by a protruding urging spring 37. Therefore, since the suction force of the solenoid body 38 does not work when the power is not energized, the lock plunger 34 is in a protruding state by the urging force of the protruding urging spring 37 and is locked and locked by the lock receiver 32 (the state of FIG. 6). ). On the other hand, when energized, the lock plunger 34 is sucked into the solenoid body 38 against the biasing force of the projecting biasing spring 37 by the suction force of the solenoid body 38 and is brought into a non-projecting state. It is released and unlocked.

  As shown in FIG. 3, the lock body 31 having such a configuration is fixedly attached to the back surface of the lighting fixture 5, specifically, the back surface of the shade bar 27 with screws or the like. The attachment position of the lock body 31 to the shade bar 27 is substantially the center of the shade bar 27 in the longitudinal direction, and corresponds to the attachment position of the lock receiver 32 to be described later to the shelf 3.

  The locking receptacle 32 has a configuration in which a locking claw 42 is assembled to the main body 41. The main body 41 has a keyhole 43, and an emergency key 44 can be inserted into the keyhole 43 to perform an emergency unlocking operation of rotating the locking claw 42 by 90 degrees. By this emergency unlocking operation, the locking of the locking claw 42 to the locking receiver 36 as will be described later is released, and the case lock 6 can be unlocked in an emergency. The main body portion 41 has a male screw portion 45 formed on the peripheral surface thereof, and a mounting nut 46 is screwed to the male screw portion 45.

  The locking claw 42 is formed by bending a strip-shaped metal plate into an L shape, and has a fixed surface portion 47 and a claw surface portion 48. Further, the hook portion 50 having the tapered surface 49 is formed by folding the tip portion of the claw surface portion 48 outward in a hook shape. The locking claw 42 having such a configuration is assembled to the main body portion 41 by fastening the nut with the fixed surface portion 47.

  The lock receiver 32 configured as described above is attached to the shelf board 3 as shown in FIGS. 3 and 5. Specifically, the shelf 3 is fixedly attached to the front edge of the shelf 3 by fastening with a mounting nut 46 of the main body 41 at a substantially central position in the longitudinal direction. The mounting position of the lock receiver 32 on the shelf plate 3 corresponds to the mounting position of the lock body 31 on the shade bar 27 as described above. And by this position correspondence, the locking for the locking between the lock main body 31 and the lock receiver 32 as described above is performed. That is, when the lock plunger 34 is in the protruding state as shown in FIG. 6 by appropriately matching the mounting position of the lock receiver 32 to the shelf 3 and the mounting position of the lock body 31 to the shade bar 27, The lock claw 42 of the lock receiver 32 can be locked to the lock receiver 36 of the lock plunger 34 so as to hook the edge of the hook-shaped portion 50, whereby the case lock 6 is locked.

  Here, the lock receptacle 32 is attached to the front edge portion at the center position of the shelf board 3 as described above. In this state, the keyhole 43 of the lock receiver 32 is exposed at the front edge of the shelf board 3 and the position thereof is the center in the longitudinal direction of the shelf board 3 that is easily noticeable by the customer. The problem is concerned. To deal with such a problem, the front shield of the shelf board 3 by the tag plate 24 of the display case 4 and the shield release by the rotation operation of the display case 4 are described. That is, by shielding the front surface of the shelf board 3 with the tag plate 24, it is possible to prevent the keyhole 43 of the lock receiver 32 from entering the eyes of the customer. On the other hand, when it becomes necessary to use the keyhole 43 of the lock receiver 32, the front shielding by the tag plate 24 can be released by rotating the display case 4, and the keyhole 43 can be exposed.

  7 and 8 schematically show the configuration of the lock collective operation mechanism 51 that can unlock and lock each case lock 6 for each display case 4 together with the case lock 6. FIG. 7 shows a locked state, and FIG. 8 shows an unlocked state. The lock batch operation mechanism 51 uses a plurality of case locks 6 as objects for unlocking / locking operations, but only one case lock 6 is shown in FIGS. 7 and 8 for simplification. As shown in FIGS. 7 and 8, the lock batch operation mechanism 51 includes a case lock power supply rail 52, a power supply device 30, and an energization switch 53 as main components.

  The case lock power supply rail 52 can supply power in common to the case locks 6 of each display case 4 in the same manner as the lighting fixture power supply rail 29 described above, and functions as a common power supply line. Electric power is supplied to the case lock power supply rail 52 from the power supply device 30 via the illumination tool power supply rail 29. Specifically, the case lock power supply rail 52 is electrically connected to the lighting fixture power supply rail 29 by the relay cord 54, and power is supplied from the power supply device 30 to the case lock power supply rail 52 via the lighting fixture power supply rail 29. Can be supplied.

  As shown in FIGS. 1 and 2, the energization switch 53 is configured to be attached to one end side of the front end edge portion of the top cover 16 so that the switch contact 55 is interposed in the middle of the energization path of the relay cord 54. And opens and closes the energization path of the relay cord 54. The energizing switch 53 has a keyhole 56 and can be operated by inserting a lock operation key 57 into the keyhole 56. That is, the energization switch 53 can be switched between opening and closing of the switch contact 55 by operating with the lock operation key 57 inserted into the keyhole 56. As the energizing switch 53 having such a configuration, for example, using an ignition switch is a preferable example from the viewpoint of miniaturization.

  Further, as shown in FIGS. 7 and 8, the lock batch operation mechanism 51 includes a lighting fixture power supply rail 29 so as to be interposed between the energization switch 53 and the power supply device 30. That is, the illuminator power supply rail 29 that supplies power to each illuminator 5 is disposed on the primary side of the energization switch 53 in the power supply system. With such a structure, even when the energization switch 53 is operated and the switch contact 55 is opened, power is supplied to the lighting fixture 5 through the lighting fixture power supply rail 29. That is, the power supply to the lighting fixture 5 can be continued through the lighting fixture power supply rail 29 regardless of whether the energization path of the relay cord 54 is opened or closed.

  Hereinafter, the unlocking / locking operation of the case lock 6 will be described. Each display case 4 in the display shelf 1 is normally locked with a case lock 6 to ensure the protection of the display items in the protective display area 23. In this state, since each case lock 6 for each display case 4 is in a non-energized state, the suction force of the solenoid main body 38 does not work, so that the lock plunger 34 protrudes as shown in FIG. The locking claw 42 protrudes by the urging force of 37, and the locking claw 42 of the locking receiver 32 is locked to the locking receiver 36 of the locking plunger 34 so that the end edge of the hook-shaped portion 50 is hooked.

  In this state, for example, in order to be able to take out the display items in the protective display area 23 according to the customer's request, the case lock 6 is unlocked. In order to unlock the case lock 6, the lock operation key 57 is inserted into the key hole 56 of the energization switch 53, the energization switch 53 is operated to the switch contact closing side, and the switch in the open state as shown in FIG. The contact 55 is switched to the closed state as shown in FIG. Then, the case lock power supply rail 52 is electrically connected to the lighting fixture power supply rail 29 via the relay cord 54, and the case lock power supply rail 52 is energized. In response to this, the solenoids 33 of the lock bodies 31 of the case locks 6 are energized all at once, and as a result, the case locks 6 are simultaneously unlocked. That is, when energized, each case lock 6 is brought into a non-protruding state by the lock plunger 34 being sucked against the biasing force of the projecting biasing spring 37 by the suction force of the solenoid body 38, as shown in FIG. As a result, the locking with the lock receiver 32 is released and the locks are unlocked all at once.

  As described above, in order to return the case locks 6 to the locked state from the state in which the case locks 6 are unlocked all at once, the lock operation key 57 is inserted into the key hole 56 of the energization switch 53 and energized. The switch 53 is operated to the switch contact open side to switch the switch contact 55 to the open state. Then, the electrical connection between the case lock power supply rail 52 and the lighting fixture power supply rail 29 by the relay cord 54 is cut off, and the case lock power supply rail 52 enters a non-energized state. And according to this, the solenoid 33 of the lock body 31 of each case lock 6 will be in a non-energized state all at once, and each case lock 6 will return to the state shown in FIG.

  FIG. 9 shows a configuration of the lock batch operation mechanism 51 when the emergency unlocking is performed using the emergency unlocking structure of the lock receiver 32. For example, if a malfunction occurs in the power supply system of the lock collective operation mechanism 51 or a malfunction occurs in the solenoid 33 of the lock body 31, the collective unlocking operation by the lock collective operation mechanism 51 cannot be performed. When unlocking is required in such a case, the emergency unlocking is performed using the emergency unlocking structure of the lock receiver 32. The emergency unlocking is performed by inserting the emergency key 44 into the key hole 43 of the lock receiver 32. Specifically, the emergency key 44 is inserted into the keyhole 43, and the emergency key 44 is rotated in the unlocking direction in the inserted state. Then, the locking claw 42 is rotated 90 degrees to be in a state as shown in FIG. That is, even if the direction of the hook-shaped portion 50 of the locking claw 42 is changed by 90 degrees and the lock plunger 34 is in a protruding state due to the non-energization of the solenoid 33 or the malfunction of the solenoid 33, the locking claw 42 Is not locked, resulting in unlocking and unlocking.

  In FIG. 10, the reverse operation of the display case 4 pull-out operation, which is an operation for enabling the display item 4 to be taken out from the display case 4, that is, a push-back operation for pushing back the display case 4 in the pulled-out state, The state of the lock body 31 and the lock receiver 32 when the lock plunger 34 is in the protruding state is shown. The display case 4 is pushed back when the case lock 6 is unlocked and the display case 4 is in the pulled-out state. Therefore, normally, in this state, the lock plunger 34 of the lock body 31 is retracted and does not protrude, and the lock receiver 32 attached to the shelf board 3 is in a state separated from the lock body 31. However, after the display case 4 is pulled out and before the display case 4 is pushed back, the lock plunger 34 of the lock body 31 may be protruded for some reason as shown in FIG. When the display case 4 is pushed back in this state, the lock receiver 32 approaches the lock body 31, and the taper surface 49 of the locking claw 42 is first moved from its distal end to the distal end of the locking receiver 36 of the lock plunger 34. It will be in the state which contacts. When this state is entered, the tip of the locking receiver 36 is pressed by the tapered surface 49, and the lock plunger 34 that is in a protruding state by receiving this pressing gradually moves as the push-back of the display case 4 progresses. It is made to retreat. When the taper surface 49 is disengaged from the latch receiver 36, that is, until the pushback of the display case 4 is completed, the pressing by the locking claws 42 is released. As a result, the lock plunger 34 returns to the original protruding position, the locking claw 42 is locked to the locking receiver 36, and the case lock 6 is locked.

  In the display shelf 1 according to the embodiment described above, the lock collective operation mechanism 51 is provided, and the case lock 6 of each display case 4 can be collectively unlocked by the lock collective operation mechanism 51. Even if it is a case where 4 is an object of interest, the salesclerk does not need to perform the unlocking operation for each of the display cases 4 one by one. Therefore, the complexity of the unlocking operation can be eliminated, and the operation burden on the store clerk regarding the unlocking operation can be greatly reduced. As a result, it is possible to prevent a decrease in the quality of service by the store clerk and a decrease in the willingness to purchase due to making the customer wait.

  In the present embodiment, in particular, the case lock 6 is electrically operated so that the collective unlocking operation is electrically performed. For example, the unlocking operation is collectively transmitted to each case lock 6 by a mechanical link mechanism, for example. Compared to such a structure, the lock batch operation mechanism 51 can be formed with a simpler structure.

  In this embodiment, in particular, the lock batch operation mechanism 51 includes a case lock power supply rail 52 that supplies power to each case lock 6 in common, a power supply device 30, and an energization switch 53. Thereby, the structure of the electric power feeding system to each case lock 6 can be simplified, and the simplification of the structure of the lock batch operation mechanism 51 can be further promoted. Further, by adopting a structure in which energization of the case lock 6 is performed by energization, it is possible to be in a non-energized state at the normal time when the case lock 6 is locked, and power consumption can be reduced. .

  In this embodiment, in particular, the energization switch 53 has a key hole 56, and the lock operation key 57 is inserted into the key hole 56, thereby switching between connection / disconnection of the case lock power supply rail 52 and the power supply device 30. The configuration is operable. As a result, the energization switch 53 can be “locked” and the lock collective operation mechanism 51 itself can be protected. As a result, the protection of the display case 4 by locking can be further enhanced. Further, the store clerk can perform the collective unlocking operation of the case lock 6 by simply turning the lock collective operation key 57 inserted into the keyhole 56, and the operation burden can be further reduced.

  In the present embodiment, in particular, the lock collective operation mechanism 51 is interposed between the energization switch 53 and the power supply device 30 and supplies power commonly to the lighting devices 5 that illuminate the display items of the display cases 4. The power supply rail 29 is used. That is, the illuminator power supply rail 29 that supplies power to each illuminator 5 is disposed on the primary side of the energization switch 53 in the power supply system. Thereby, even when the energization switch 53 is operated and the case lock power supply rail 52 and the power supply device 30 are disconnected, the power supply to the lighting device 5 is performed via the lighting device power supply rail 29. . That is, regardless of the switching operation of the energization switch 53, the power supply to the lighting fixture 5 can be continued through the lighting fixture power supply rail 29. In addition, the structure of the power supply system to each lighting tool 5 can be simplified, and the structure of the lock batch operation mechanism 51 can be further simplified.

  In the present embodiment, the case lock 6 is particularly configured by an electric lock body 31 and a lock receiver 32, and is locked by locking between the lock body 31 and the lock receiver 32. By configuring the case lock 6 with the lock body 31 and the lock receiver 32 in this way, it is possible to provide a structure that can be individually unlocked in an emergency via the lock receiver 32 as in this embodiment. The functionality of the lock 6 can be expanded.

  In the present embodiment, the lock body 31 has a solenoid 33 as a drive source for unlocking and locking. Thus, the locking structure for locking the case lock 6 by locking between the lock body 31 and the lock receiver 32 by using the solenoid 33 as a drive source for unlocking and locking the solenoid 33 is used. It can be realized with a simpler structure.

  In this embodiment, in particular, the lock body 31 includes a lock plunger 34 and a protrusion biasing spring 35, and the lock receiver 36 of the lock plunger 34 in the protruded state is locked to the lock claw 42 of the lock receiver 32. By doing so, it is configured to lock. By configuring the lock body 31 in this manner, the case lock 6 can be unlocked when energized, and power consumption related to the case lock 6 can be saved. That is, in the lockable display shelf 4, the case lock 6 is normally in the locked state, and the unlocked state is much shorter than the locked state time. The power consumption related to the case lock 6 can be kept to a minimum by opening the lock when energized.

  Further, particularly in the present embodiment, the locking claw 42 has the tapered surface 49, and the taper surface 49 is the tip of the lock plunger 34 when the display product unloading operation is performed in the protruding state of the lock plunger 34. The lock plunger 34 that is in the protruding state is pushed backward to be locked, and is locked to the lock receiver 36 to be locked. Thereby, even if it becomes the above situations, the display item T disabling operation of the display case T can be performed without hindrance, and thereby the usability of the case lock 6 can be improved.

  Further, in the present embodiment, in particular, the lock receiver 32 has a key hole 43, and the emergency key 44 is inserted into the key hole 43 so that the unlocking operation can be performed. Thereby, for example, even when the power supply device 30 of the lock collective operation mechanism 51 or the solenoid 33 of the lock body 31 is broken, the case lock 6 can be individually unlocked by the unlocking operation through the lock receiver 32. It is possible to respond to time.
