Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a double-lock device in which a replacement key cannot be removed from a lock body, and further relates to a prize providing method for a game machine that can make a large stuffed animal or the like a prize by a locker to which the double-lock device is attached.
[0002]
[Prior art]
A game center popular among the youth generation is a game arcade in the city where various game machines, also called arcade games, are lined up. In order to play with a game machine, the game starts when coins purchased in cash are inserted into the game machine, and it is generally possible to replay when a high score is obtained in the game. This type of game center is already in a busy area, and it is easy to compete with other game industries such as pachinko and mahjong when acquiring customers, and game center managers make various attempts to attract customers. It is necessary to do.
[0003]
For example, a conventional game center needs to be transformed, and recently, various prize machines that can operate in a casino-like style or obtain a prize such as a UFO catcher (trade name) are installed. Casino-style game centers challenge various games by changing cash to chips. However, no matter how much you win, if you exchange chips, you will be charged with gambling charges. It's not too many, and there aren't many people playing with it that can be exchanged for cash.
[0004]
[Problems to be solved by the invention]
In a prize machine capable of acquiring a prize, it is necessary to store character goods, toys, confectionery, miscellaneous goods, etc. as prizes in the machine. The size of the prize machine has a certain limit so as to correspond to the site area of the game center, so the number and size of prizes that can be stored inside the machine is naturally limited, and it is large enough to attract young women's interest. A stuffed animal cannot be used as a prize. Even if it is possible to exchange large prizes at the prize exchange, in this case, the game cannot be advanced while checking the actual goods, and this type of prize machine gives the player The impact is not so great.
[0005]
On the other hand, in a casino-like game center, even if it is not possible to mount a game machine with a function for directly exchanging chips that have been won, it can be exchanged for a predetermined prize according to the number of acquired chips. In this case, it is necessary to exchange the earned chips for the number of prizes at the prize exchange, and it is necessary to newly establish a prize exchange and hire employees in charge, which significantly increases the necessary expenses at the game center. End up. This is the same even when a large stuffed toy is exchanged at a prize exchange for a prize machine from which a prize can be obtained. Even though the prize exchange itself is the same as the pachinko game hall, the game center is clearly disadvantageous in that it cannot be redeemed.
[0006]
The present invention has been proposed with respect to a lock used for a locker capable of storing a large-sized product, and can be used to solve the above-described problems related to a game center. An object of the present invention is to provide a double-locking device that can be applied to a rental post, a glass case for instant sale of goods, etc. by using two keys of a management key and a replacement key together. Another object of the present invention is to provide a locker that can be opened and closed without coins and cannot be lost because a replacement key cannot be removed. Another object of the present invention is to provide a prize providing method for a gaming machine that does not require a prize exchange and chip conversion work in a game center.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, in the double locking device according to the present invention, when the latch is in the locking position, the unlocking operation by the management key becomes invalid and only the replacement key can retract the latch. When the replacement key is turned and the latch is driven to the unlocked position, the locking operation is disabled while the replacement key remains inserted in the lock. On the other hand, the latch can be advanced to the locking position only with the management key, and when the latch reaches the locking position, the replacement key can be pulled out from the lock.
[0008]
More specifically, the double locking device of the present invention includes a management and replacement lock attached to the frame plate at a predetermined interval, and a guide plate horizontally fixed to the frame plate between the two locks. A latch that is movable back and forth along the guide plate, a spring that biases the latch backward, a locking lever that is fixed to the rotor of the lock for management, and a spring that is fixed to the rotor of the replacement lock and is An unlocking lever that biases forward. In this double-locking device, when the latch is advanced by rotating the locking lever, the unlocking lever is rotated and the latch is fixed in the locking position with the advancement, while the unlocking lever is turned from the fixed state of the latch. When released, the latch is retracted by a spring, and the retracting action causes the latch to reach the unlocked position. In this double locking device, a rectangular latch is formed with a horizontally long opening and a downward notch, and a horizontal bar with a compression spring is fixed horizontally inside the latch, and the pin of the locking lever is fitted into the horizontally long opening of the latch. And it is preferable that the pin of the unlocking lever is engageable / detachable with the lower notch of the latch.
[0009]

A locking device. What is necessary is just to attach the said double lock apparatus to this locker.
[0010]
The prize providing method according to the present invention sends out a predetermined replacement key as a prize from the game machine in accordance with the points obtained by playing the game machine. In this prize providing method, at least one locker having a plurality of storage rooms is installed in the vicinity of the game machine, and each front door of the storage room of the locker has a transparent door plate at least partially. When the prize is stored in the room and the latch is in the locked position, the unlocking operation by the management key is invalid, and turning the replacement key to drive the latch to the unlocked position opens the front door and removes the prize. It can be taken out and the replacement key is still inserted in the lock, and the locking operation becomes invalid.When closing the front door, the latch is driven to the locked state only with the management key, and when the latch reaches the locked position, the replacement key is used. The key can be pulled out of the lock.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
The double-locking device 1 of the present invention uses a normal cylinder lock as the lock 3 and a pin tumbler lock as the lock 5, and the replacement key 70 (FIG. 8) for the pin tumbler lock is relatively thick and large. In addition, since it has a presence as a prize of a game and it is difficult to forge the key, it is extremely useful when used for storing goods. In the double locking device 1, the locks 3 and 5 can both be determined as ordinary cylinder locks or pin tumbler locks.
[0012]
In the double locking device 1, it is also possible to combine a plurality of frame plates 2 into a hermetically sealed shape or to punch out a part of the frame plate 2 to serve as a guide plate. The spring 36 for urging the latch 7 rearward may use another elastic member such as a leaf spring in addition to a normal compression spring, and the same applies to the coil spring 80.
[0013]
Although the replacement key 70 remains inserted in the lock 5 when unlocked, it is unlikely to be lost. However, the replacement key 70 is overwhelmed by an unspecified number of humans who play the game. It will occur. The pin tumbler lock of the lock 5 can be configured such that when the key 70 is lost, only the lock body 74 can be pulled forward from the frame plate 2 without disassembling the entire double-lock device 1. . In this case, it is necessary to fix the cylindrical body into which the lock body 74 is fitted to the frame plate, to separate the rear part of the rotor 66, and to have a joint structure that can be connected to the front part of the rotor of the lock body when mounted.
[0014]
In the locker 112, each front door 116 cannot be locked without permission, and a person who does not have the management key 50 cannot use it arbitrarily. The front door may be either a normal swivel type or a roll-up shutter type. If each storage chamber 114 is open at the time of unlocking, it is preferable that articles can be put into the storage chamber without further reduction. The management key 50 may be different for each storage chamber 114 of the locker 112 or may be the same in all the storage chambers. If the key is the same, the product storage operation is quickened.
[0015]
In the prize providing method of the present invention, only a replacement key is sent out from a game machine as a prize, and the size of a prize machine or the like can be drastically reduced just by reducing the key. Can also be added. A game machine to which this prize providing method can be applied is not only a prize machine such as a UFO catcher (trade name), a mini crane, a pachinko game, and a slot machine, but also a general game machine with some improvements.

The support bar 38 has substantially the same length as the latch 7, and the round head bolt 44 inserted through the rear wall 42 of the latch is fastened to the screw hole 46 (FIG. 6) on the rear end surface of the support bar. The rod is fixed in parallel with the latch 7. The spring 36 is interposed between the frame plate side surface portion 14 and the latch rear wall 42 and urges backward when the latch 7 advances.
[0019]
The locking lever 28 is fixed to the rotor 48 of the upper management cylinder lock 3, and the rotor can be rotated by the management key 50 (FIG. 7). As shown in FIG. 5, the cylinder lock 3 includes a non-circular cross-section lock main body 54 having a front large-diameter portion 52 and a rear male screw portion 53, and a rotor 48 that is rotatably fitted in the main body. The male threaded portion 53 of the lock body 54 is fitted into a non-circular hole 56 of the same cross section provided in the frame plate surface portion 4, and is fixed to the frame plate 2 by fastening of a thin nut 58, and the front surface of the cylinder lock 3 is the frame plate. 2 (see FIG. 1). On the other hand, the rear portion of the rotor 48 is a non-circular body provided with a male screw. After inserting the cam 60 having the through-hole having the same cross section, the locking lever 28, and the toothed washer 62 into the rotor 48, the rotor 48 is tightened with a nut 64. Then, the cam 60 and the lever 28 are fixed to the rotor 48. A part of the cam 60 is locked to the rear protrusion 65 (FIG. 2) of the lock body 54, thereby restricting the rotation of the rotor 48.
[0020]
Referring to FIG. 2, the non-circular through hole 67 for inserting the rotor in the locking lever 28 is located above the lever, and the inward pin 30 is located below the lever and slightly shifted to the left from the lever center line. . The pin 30 is always located in the lateral opening 24 of the latch 7 and can be pivoted only in the lateral opening 24 in the latch advance position, that is, the locking position, and does not affect the movement of the latch 7. As is apparent from FIG. 4, in the retracted position of the latch, that is, the unlocked position, the pin 30 is in contact with the inner surface of the laterally long opening 24, and when the pin is turned, the latch 7 is advanced. The lever 28 may be slightly inclined due to the slight play.
[0021]
On the other hand, the unlocking lever 32 is fixed to the rotor 66 of the replacement cylinder lock 5 below, and the rotor can be rotated by the replacement key 70 (FIG. 8). As shown in FIG. 5, the cylinder lock 5 includes a non-circular cross-section lock main body 74 having a front large-diameter portion 72 and a rear male screw portion 73, and a rotor 66 rotatably fitted in the main body. The male threaded portion 73 of the lock body 74 is fitted into a non-circular hole 76 having the same cross section provided in the frame plate surface portion 4, and is fixed to the frame plate 2 by fastening of a thin nut 78, and the front surface of the cylinder lock 5 is the frame plate. 2 (see FIG. 1). On the other hand, the rear part of the rotor 66 is a non-circular body provided with a male screw. After the coil spring 80 is fitted to the lock body 74, the cam 81 having the through-hole having the same cross section as the rotor rear part and the unlocking lever 32 are provided. Then, the toothed washer 82 is inserted into the rotor 66 and then tightened with the nut 84 to fix the cam 81 and the lever 32 to the rotor 66. A part of the cam 81 is locked to the rear protrusion 83 (FIG. 2) of the lock body 74, thereby restricting the rotation of the rotor 66.
[0022]
Referring to FIG. 2, the non-circular through hole 85 for inserting the rotor in the unlocking lever 32 is located below the lever, and the inclination angle of the through hole is adjusted so that the lever 32 is inclined to the left side from the key insertion position of the rotor 66. The inward pin 34 is located above the lever. The one end 87 of the coil spring 80 is bent in a U shape and hooked to the side surface of the lever 32, and the other end is locked to the side surface portion 14 of the frame plate 2, so that the unlocking lever 32 is always in FIG. It is energized clockwise. For this reason, the pin 34 contacts the inner side surface of the lower notch 26 at the latch advance position to prevent the latch 7 from retracting, and at the latch retracted position, the pin 34 contacts the side surface latched away from the notch 26 (FIG. 4). reference).
[0023]
In the double locking device 1, the upper cylinder lock 3 that can be locked with the management key 50 (FIG. 7) may be a normal cylinder lock, and the lower cylinder that can be unlocked with the replacement key 70 (FIG. 8). For the lock 5, for example, a pin tumbler lock is used (see FIGS. 1 and 8). The cylindrical pin tumbler lock 5 includes a lock body 74, a fixed body (not shown) stationary at a rear portion in the lock body, and a rotor 66 supported by the fixed body and rotatable in the lock body 74 (FIG. 5). With.
[0024]
As shown in FIG. 1, a flange portion 88 is formed on the front surface portion of the lock body 74 inward from the inner peripheral edge to the key hole 86, and the protruding portion 90 of the replacement key 70 is formed on a part of the flange portion. , 90 through which recesses 92 and 92 can pass are formed. The annular rear end face of the flange portion 88 functions as a stopper to prevent the protruding portions 90 and 90 of the pivoted key 70 from coming into contact with each other. The axial movement of the rotor 66 is regulated by an annular step (not shown) on the inner peripheral wall of the lock body 74. The fixed body in the lock body 74 has an outer diameter substantially equal to the inner diameter of the lock body, and is fixed integrally to the lock body 74 by a shaft pin (not shown). This fixed body has a central hole formed in the front end surface thereof, and a rotor shaft portion 94 (FIG. 5) extending rearward from the intermediate large diameter portion of the rotor 66 is fitted into the central hole. Is exposed rearward from the lock body. On the other hand, a small-diameter portion 96 protrudes forward from the intermediate large-diameter portion of the rotor 66, and a notch groove 100 for engaging the inward projection 98 of the key 70 is formed in the small-diameter portion.
[0025]
On the front end surface of the intermediate large-diameter portion of the rotor 66, eight through-pin holes are provided in four equal parts on the circumference centered on the axis, and the code pins 102 (FIG. 1) are inserted into the respective through-pin holes. However, the through pin hole is not formed in the vicinity of the recesses 92 and 92. Although not shown, the length of the code pin 102 is the same or different for each, and is set according to the depth of the pin pressing cam groove 104 provided in the key 70. On the other hand, a bottomed pin insertion hole is formed in the fixed body in parallel with the axis so as to correspond to the eight through-pin holes formed in the rotor 66, and a small coil spring and an underpin are respectively provided in each pin insertion hole. Contains pins. The underpin is urged forward by a small coil spring, the cord pin projects forward through the underpin, and the tip of the cord pin 102 abuts on the annular rear end surface of the inward flange portion 88. The length of each underpin is usually the same, and a leg portion is provided below the underpin, and a coil spring is fitted to the leg portion. The length of the leg portion is such that the key 70 is inserted from the insertion port 86 and the cord pin 102 is pushed in, and the contact position between the rear end surface of each cord pin and the tip portion of the underpin is the middle large diameter portion of the rotor 66. The pin insertion hole may be bottomed or penetrated so as not to interfere with the contact position between the rear end surface and the front end surface of the fixed body. The tip of the underpin is processed into a hemispherical shape so that the rear end surface of the intermediate large-diameter portion of the rotor 66 and the front end surface of the fixed body are in contact with each other and rotate easily.
[0026]
When the lower cylinder lock 5 is a pin tumbler lock, a replacement key 70 having a front portion 106 of a cylinder is used, and the key is relatively large and has a presence as a prize. This pin tumbler lock is frequently used because it is difficult to counterfeit the key 70, and it is common to perform unlocking and locking with a unique key corresponding to each pin tumbler lock, as with a normal cylinder lock. . Pin tumbler locks are often attached to the doors of machines such as pachinko machines and vending machines, so that if the key is lost, only the lock body can be pulled forward from the frame plate 2 without disassembling the entire lock. It is also possible to configure.
[0027]
In the double locking device 1, when the latch 7 is in the locking position as shown in FIGS. 1 and 2, even if the management key 50 is inserted into the key hole 108 of the lock 3 and rotated, the rotation of the locking lever 28 is a cam. The lever pin 30 is merely pivoted within the latch lateral opening 24, and the latch 7 cannot be retracted.
[0028]
On the other hand, when the replacement key 70 is inserted into the key hole 86 of the lock 5, the protrusions 90, 90 in the key front portion 106 pass through the recesses 92, 92 of the flange portion 88, depending on the depth of each cam groove 104. Eight cord pins 102 are pushed downward. As a result, the underpins are pushed downward through the cord pins 102, and the tip positions of all eight underpins are aligned with the abutting position of the rear end face of the intermediate large diameter portion of the rotor 66 and the front end face of the fixed body. In addition, the key inward projection 98 is inserted into the notched groove 100 of the small diameter portion 96 of the rotor 66, so that the rotor 66 of the lock 5 can be turned by the key 70. When the key 70 is rotated clockwise in FIG. 1, that is, when the unlocking lever 32 is rotated counterclockwise in FIG. 2 against the elasticity of the coil spring 80, the lever pin 34 is disengaged from the notch 26 of the latch 7, and the latch 7 is elastic of the spring 36. Retreat by. This backward movement is performed until the pin 30 of the locking lever 28 stopped by the cam 60 comes into contact with the inner surface of the horizontally long opening 24.
[0029]
When the unlocking lever 32 is turned to retract the latch 7, the pin 34 of the unlocking lever 32 comes into contact with the latch lower side surface 110 as shown in FIG. 4, and the lever 32 cannot return to the key insertion position in FIG. For this reason, the protrusions 90, 90 of the replacement key 70 are not returned to the positions of the recesses 92, 92 of the flange portion 88 in the lock 5, and remain inserted into the lock 5.
[0030]
The door opens at the latched position in FIG. When the locker storage is taken out and the door is closed again, the management key 50 is inserted into the key hole 108 of the lock 3 and the locking lever 28 is turned counterclockwise in FIG. And the latch 7 can be advanced through the oblong opening 24. When the notch 26 moves forward with the advance of the latch 7 and exceeds the position of the pin 34 of the unlocking lever 32, the unlocking lever pivots to the position of FIG. 2 by the elasticity of the coil spring 80, and the pin 34 fits into the notch 26. As a result, the latch 7 is stationary at the advanced position and cannot be retracted. As a result of this turning, the protrusions 90 and 90 of the replacement key 70 return to the positions of the recesses 92 and 92 of the flange portion 88, and the key 70 is pushed by the repulsive force of each cord pin 102 and from the key hole 86 of the lock 5. I can take it out.
[0031]
The double locking device 1 can be attached to a locker 112 as illustrated in FIG. The locker 112 has five rectangular parallelepiped-shaped storage chambers 114 that are juxtaposed in the vertical direction and have a small volume downward, and a front door 116 of a predetermined size is vertically disposed on the front side of each storage chamber. The front door is attached so as to be openable and closable in the horizontal direction. All the front doors 116 usually have the same appearance, and a transparent door plate 120 is fixed to the center of an opaque frame 118. In order to attach each front door 116 to the double lock device 1, a through hole corresponding to the front shape of the locks 3 and 5 is provided in the vertical frame portion of the frame body 118, and the double lock device is provided from the rear side of the vertical frame portion. 1 may be contacted, pinned at the through holes 122 and 122 (FIG. 1), and a decorative plate may be attached to the front side.
[0032]
In each storage chamber 114 of the locker 112, a receiving plate (not shown) provided with a rectangular hole is attached to the inner side surface that comes into contact with the plate surface portion 4 of the double-lock device 1 when the front door 116 is closed. The rectangular hole of the receiving plate is a bottomed hole into which the front portion 18 of the latch 7 is fitted.
[0033]
In the locker 112, if a prize such as a stuffed animal is stored in each storage chamber 114 and the double lock device 1 is locked, the unlocking operation is invalidated by the management key 50 and the door 116 cannot be opened. . At the time of locking, although the latch 7 is retracted with the replacement key 70 and the door 116 is opened, the prize can be taken out, but the replacement key 70 remains inserted in the lock 5 and can be taken home or used for other purposes. I can't do it.
[0034]
Further, since it is impossible to lock the opened door 116 without permission, a person who does not have the management key 50 cannot use the locker 112 without permission. The management key 50 may be the same for each storage chamber 114 of the locker 112, and the lock 7 can be moved forward by the key to lock the lock. When the latch reaches the lock position, the replacement key 70 is removed from the lock 5. Pull out and collect them as prizes and store them in a prize machine.
[0035]
In FIG. 10, the usage example of the locker 112 which attached the double lock apparatus 1 to each front door is shown. The locker 112 is installed in parallel with another locker 126 having the same dimensions via a horizontal decorative bridge member 124, and the distance between the lockers 112 and 126 can be adjusted as appropriate according to the lateral width of the game machine 128 arranged in the center. . Another locker 126 has six storage rooms and is slightly different from the locker 112 in size. The game machine 128 may be of any type as long as it is a normal prize machine, and only stores a large number of replacement keys 70, so that the internal volume can be made smaller than that of a normal product.
[0036]
In the lockers 112 and 126, a prize such as a large stuffed toy is put in each storage room in advance using the management key 50. When playing with the game machine 128, a large number of prizes stored in the lockers 112 and 126 can be seen in front of the eyes through the transparent door plate, and a large and expensive product can be used as a prize. Also, the willingness to get your favorite prizes will spring up.
[0037]
The game machine 128 only needs to send out the replacement key 70 as a prize according to the points obtained in the game. A player who has obtained a replacement key 70 of a predetermined number may insert the key into the key hole of the lock 5 and open the door 116 in the storage room that matches the key number to take out a predetermined prize. When the door 116 is unlocked, the replacement key 70 remains inserted in the lock 5 and the key cannot be removed without permission. When the door 116 is closed, the management key 50 is inserted into the lock 3 and turned. When the latch 7 reaches the lock position and is locked, the replacement key 70 can be pulled out from the lock 5.
[0038]
【The invention's effect】
In the double-locking device according to the present invention, since the replacement key cannot be pulled out from the lock body when unlocked, the key is less likely to be lost, and unauthorized use of the replacement key is also reduced. In addition, when the double-locking device of the present invention is applied to a locker or the like, the administrator holds a management key for locking even if there are a large number of storage rooms in which the double-locking device is installed. Therefore, the partner can be confirmed each time when the article is stored and the replacement key is handed over. The double-locking device of the present invention can be applied not only to game machines, but also to rental posts, glass cases for commodity sales, bank safety deposit boxes, hotel rental cabinets, and the like.
[0039]
In the locker of the present invention, a person who does not have a management key cannot use the locker without permission, and there is no fear that dangerous goods or stolen goods are stored in the storage room. If the management key to be used is the same for each storage room of the locker, it becomes easy to carry individual items into each storage room and lock them, and the product storage operation is completed quickly. Moreover, since the management key only for locking is not stolen and the product itself is not stolen, it is easy to store the management key and theft is less likely to occur.
[0040]
Since the prize providing method according to the present invention provides only a replacement key as a prize for a game machine, the game machine can be simplified and miniaturized. In this prize providing method, a prize can be stored in the locker storage room, so that a large product such as a stuffed toy can be provided as a prize. This gift providing method has an economic advantage that the player can directly see the product, enhances the interest of the game, and eliminates the need for a chip conversion or gift exchange employee.
