Definitions
- the present invention relates to a locking device of an automatic vending machine and, more specifically, to a locking device of an automatic vending machine which maintains a state where a door body closes a front opening of an automatic vending machine main body due to an engagement between a locking member arranged on one of the automatic vending machine main body and the door body and a slider arranged on the other of the automatic vending machine main body and the door body, and which allows the door body to perform an opening movement and the front opening of the automatic vending machine main body to be opened due to a release of the engagement between the locking member and the slider.
- an automatic vending machine includes an automatic vending machine main body which has a cuboid shape with an open front surface and which internally stores products, and a door body arranged so as to be capable of opening and closing the front opening of the automatic vending machine main body.
- a rectangular opening is formed on the door body, and a slider supported by a supporting member so as to be slidable in a vertical direction between a locking position and a releasing position is arranged on the door body.
- the slider has an approximately C-shaped transverse section and is provided with a rectangular opening which allows entry by a locking member that is a hook-like metal fixture arranged on the automatic vending machine main body.
- a rectangular hole is formed on the slider and a rod (an elongated columnar portion) of a cylinder lever is inserted into the rectangular hole.
- the cylinder lever is coupled to an inner cylinder of a cylinder lock which is arranged on a front surface of the door body and which has a key insertion slot.
- the cylinder lever performs an unlocking movement around its own axis in response to an unlocking operation of a key inserted into the key insertion slot and performs a locking movement around its own axis in response to a locking operation of the key.
- the slider moves from the locking position to the releasing position as the rod abuts an upper edge portion of the rectangular hole due to an unlocking movement of the cylinder lever, and moves from the releasing position to the locking position as the rod abuts a lower edge portion of the rectangular hole due to a locking movement of the cylinder lever.
- the locking member In a state where the door body blocks the front opening of the automatic vending machine main body, the locking member enters the rectangular opening of the slider which has descended to the locking position and engages an upper edge portion of the rectangular opening. Subsequently, when an ascending movement of the slider to the releasing position is performed via the cylinder lever due to an unlocking operation of the key, the engagement between the locking member and the slider is released. Therefore, by having the door body perform an opening movement, the front opening of the automatic vending machine main body is opened and restocking of products and the like can be performed. Moreover, the slider having performed an ascending movement to the releasing position is held at the releasing position due to an engagement of a slider holding member with the rectangular opening.
- the locking member enters the rectangular opening of the slider held at the releasing position by the slider holding member, the locking member presses down the slider holding member to release the engagement by the slider holding member, and the slider automatically moves from the releasing position to the locking position due to the slider's own weight. Accordingly, the upper edge portion of the rectangular opening of the slider and the locking member abut each other and the slider and the locking member engage each other. Due to the engagement between the slider and the locking member in this manner, a state where the door body closes the front opening of the automatic vending machine main body is retained.
- the slider holding member which holds the slider at a releasing position is equipped with a function for automatically engaging the slider and the locking member with each other by closing the door body to cause the slider to descend to the locking position. Therefore, an inconvenience of performing an unlocking operation of the key when closing the door body to cause the slider to descend and engage the locking member can be eliminated (for example, refer to Patent Document 1).
- Patent Document 1 Japanese Patent Application Laid-open No. 2002-342827
- a rectangular hole is formed in the slider and a rod (an elongated columnar portion) of a cylinder lever is inserted into the rectangular hole.
- the cylinder lever performs an unlocking movement around its own axis in response to an unlocking operation of a key inserted into a key insertion slot arranged on a front surface of the door body and performs a locking movement around its own axis in response to a locking operation of the key.
- the slider moves from the locking position to the releasing position as the rod abuts an upper edge portion of the rectangular hole due to an unlocking movement of the cylinder lever, and moves from the releasing position to the locking position as the rod abuts a lower edge portion of the rectangular hole due to a locking movement of the cylinder lever.
- the cylinder lever performs an unlocking movement and the slider moves from the locking position to the releasing position.
- the slider having moved to the releasing position is held by the slider holding member. Once the slider is held at the releasing position, an engaged state with the locking member is released and the front opening of the automatic vending machine main body can now be opened by having the door body perform an opening movement.
- a key is inserted into the key insertion slot by a routeman who is responsible for restocking products, maintenance, and the like.
- a position at which a key is inserted and removed is set to a fixed position (for example, the position of 12 o'clock on a clock). Therefore, when an unlocking operation is performed by inserting a key into the key insertion slot or, in other words, when an unlocking operation is performed by inserting a key into the key insertion slot and turning the key clockwise by 90 degrees, the key cannot be removed in this state.
- a locking operation (which involves turning the key counter-clockwise by 90 degrees to restore the key to the original position) must be performed.
- the slider to which the cylinder lever is coupled, has ascended to a releasing position due to the unlocking operation and is held by the slider holding member. Therefore, the key cannot be removed from the key insertion slot unless either the door body is closed or the maintained state of the slider by the slider holding member is released. Furthermore, the routeman generally carries the key together with keys of other automatic vending machines on a mounting portion such as a dedicated cord or the like on a belt loop of his/her own uniform.
- the routeman in order to perform restocking of products, the routeman first inserts a key into the key insertion slot and performs an unlocking operation. Accordingly, the slider moves from the locking position to the releasing position via the cylinder lever and an engagement between the slider and the locking member is released. Consequently, while the front opening of the automatic vending machine main body can be opened by having the door body perform an opening operation, since the key is attached to the routeman's own uniform via a mounting member such as a cord as described above, the key must be removed from the key insertion slot in order to perform restocking of products or the like.
- a locking operation of the key is performed in order to remove the key from the key insertion slot. Since a locking operation is performed to remove the key from the key insertion slot in this manner, the slider has made a sliding movement from the releasing position to the locking position via the cylinder lever. While the front opening of the automatic vending machine main body must be closed by having the door body perform a closing operation after the restocking of products or the like, a locking operation has been performed in order to remove the key from the key insertion slot and the slider has moved to the locking position.
- the routeman since the locking member is unable to enter the rectangular opening of the slider even if a closing movement is performed as-is by the door body, the routeman must once again insert the key into the key insertion slot and perform an unlocking operation, move the slider from the locking position to the releasing position, and while maintaining this state, have the door body perform a closing movement to close the front opening of the automatic vending machine main body and have the slider and the locking member engage each other in order to remove the key from the key insertion slot.
- closing the front opening of the automatic vending machine main body by having the door body perform a closing operation after opening the front opening of the automatic vending machine main body by having the door body perform an opening operation requires that the key is once again inserted into the key insertion slot to perform an unlocking operation, making servicing such as restocking of products a hassle.
- the present invention has been made in consideration of the above circumstances, and an object thereof is to provide a locking device of an automatic vending machine which is capable of preventing a slider from moving from a locking position to a releasing position even if an elongated rod-like body such as a tool is entered through a rectangular opening.
- another object of the present invention is to provide a locking device of an automatic vending machine which is capable of securing favorable anti-theft performance while improving efficiency of servicing such as restocking of products.
- a locking device of an automatic vending machine includes: a locking member attached to one of an automatic vending machine main body which has a cuboid shape with an open front surface and which internally stores products, and a door body arranged so as to be capable of opening and closing the front opening of the automatic vending machine main body; and a slider having an approximately C-shaped transverse section and arranged on the other of the automatic vending machine main body and the door body so as to be movable between a locking position at which the slider is capable of engaging the lock member having entered through a rectangular opening formed on the slider and a releasing position at which the engagement with the locking member is released, the locking device of an automatic vending machine maintaining a state where the door body closes the front opening of the automatic vending machine main body due to the engagement between the locking member and the slider and allowing the door body to perform an opening movement and the front opening of the automatic vending machine main body to be opened due to a release of the engagement between the locking member and
- a locking device of an automatic vending machine according to claim 2 of the present invention is the locking device of an automatic vending machine according to claim 1, further including a slider holding member which holds the slider at the releasing position when the slider moves from the locking position to the releasing position and which releases holding of the slider and allows the slider to move from the releasing position to the locking position when the locking member enters the slider positioned at the releasing position and the slider holding member is pressed down by the locking member, wherein the slider holding member is formed with a notched portion which causes a tip of an elongated rod-like body to abut the abutting piece when the rod-like body is entered through the rectangular opening.
- a locking device of an automatic vending machine includes: a locking member attached to one of an automatic vending machine main body which has a cuboid shape with an open front surface and which internally stores products, and a door body arranged so as to be capable of opening and closing the front opening of the automatic vending machine main body; and a slider having an approximately C-shaped transverse section and arranged on the other of the automatic vending machine main body and the door body so as to be movable between a locking position at which the slider is capable of engaging the lock member having entered through a rectangular opening formed on the slider and a releasing position at which the engagement with the locking member is released, the locking device of an automatic vending machine maintaining a state where the door body closes the front opening of the automatic vending machine main body due to the engagement between the locking member and the slider and allowing the door body to perform an opening movement and the front opening of the automatic vending machine main body to be opened due to a release of the engagement between the locking member and the slider, the locking device of an automatic vend
- a locking device of an automatic vending machine is the locking device of an automatic vending machine according to claim 3, wherein the restricting member is arranged so as to be swingable around its own axis between a restricting position and an allowing position, restricts displacement of the coupling member and suppresses movement of the slider from the locking position to the releasing position when the restricting member is positioned at the restricting position, and allows displacement of the coupling member when the restricting member is positioned at the allowing position
- the locking device of an automatic vending machine further includes a guiding member which is interposed between the cylinder lever and the restricting member and which is abutted by the cylinder lever and causes the restricting member to swing from the restricting position to the allowing position when the cylinder lever performs the unlocking movement.
- a locking device of an automatic vending machine according to claim 5 of the present invention is the locking device of an automatic vending machine according to claim 3 or 4, further including a slider holding member which holds the slider at the releasing position when the slider moves from the locking position to the releasing position and which releases holding of the slider and allows the slider to move from the releasing position to the locking position when the locking member enters the slider positioned at the releasing position and the slider holding member is pressed down by the locking member.
- the slider since the slider has an abutting piece which is integrally formed at a predetermined location of an extending end portion of the slider and which abuts a tip of an elongated rod-like body when the rod-like body is entered through the rectangular opening, both the tip and a middle part of the rod-like body abut the slider that is a same member. Therefore, even if the rod-like body is swung with its tip as a fulcrum, only the slider deforms due to the principle of leverage and there is no risk of the slider separating from the slider holding member or the like and performing a sliding movement from the locking position to the releasing position. As a result, an advantageous effect is achieved in that the slider can be prevented from moving from the locking position to the releasing position.
- a coupling member integrally arranged with the slider is displaced by being abutted by the cylinder lever and moves the slider from the locking position to the releasing position when the cylinder lever performs an unlocking movement and constantly allows a locking movement by the cylinder lever when the cylinder lever performs a locking movement. Therefore, when a closing movement of the door body is performed after performing servicing such as restocking of products, there is no longer a need to once again insert a key into the key insertion slot and servicing such as restocking of products becomes hassle-free.
- a restricting member normally restricts displacement of the coupling member and suppresses movement of the slider from the locking position to the releasing position and allows displacement of the coupling member when the cylinder lever performs an unlocking movement
- anti-theft performance can be secured when a state is maintained where the door body closes the front opening of the automatic vending machine main body.
- an advantageous effect is achieved in that anti-theft performance can be favorably secured while improving efficiency of servicing such as restocking of products.

- a groove portion 341 opened to below and a weight portion 342 are respectively formed on the restricting member 34, and the restricting member 34 is positioned at a restricting position due to the weight portion 342 as shown in FIG. 3 .
- the restricting member 34 is positioned at the restricting position, entry by the hook portion 323 of the coupling member 32 into the groove portion 341 is allowed.
- the groove portion 341 is positioned in an area above the hook portion 323.
- a guiding member 38 is interposed between the restricting member 34 and the cylinder lever 33.
- the guiding member 38 is coupled to the restricting member 34.
- the guiding member 38 is abutted against a part of a peripheral edge portion of the elliptically-shaped portion 331 of the cylinder lever 33 and, as shown in FIG. 7 , swings the restricting member 34 positioned at the restricting position upward against a force of gravity of the weight portion 342 and moves the restricting member 34 to the allowing position.
- the restricting member 34 is positioned at the allowing position before the rod member 332 of the cylinder lever 33 abuts the horizontal portion 321 of the coupling member 32 and, as a result, the hook portion 323 of the coupling member 32 disengages from the groove portion 341 of the restricting member 34.
- servicing such as restocking of products with respect to the inside of the main body cabinet 1 can be performed as follows.
- the locking device maintains a state where the outer door 20 closes the front opening of the main body cabinet 1
- the slider 31 constituting the locking device is positioned at the locking position and is in engagement with the locking member R
- the restricting member 34 is positioned at the restricting position.
- the cylinder lever 33 performs an upward unlocking movement as shown in FIG. 7 . Due to the guiding member 38 being abutted by a part of the peripheral edge portion of the cylinder lever 33 in the process of unlocking, the restricting member 34 swings from the restricting position toward the allowing position against a force of gravity of the weight portion 342. Accordingly, the hook portion 323 of the coupling member 32 disengages from the groove portion 341 of the restricting member 34.
- the restricting member 34 when the restricting member 34 is positioned at the restricting position, the restricting member 34 restricts upward displacement of the coupling member 32 and suppresses a sliding movement of the slider 31 from the locking position to the releasing position, and when the restricting member 34 is positioned at the allowing position, the restricting member 34 allows displacement of the coupling member 32.
- the latch portion 3611 of the slider holding member 36 protrudes from the slider opening 3111 toward the rear surface side and engages with the upper edge portion of the slider opening 3111, and holds the slider 31 in a state where the slider 31 is positioned at the releasing position.
- an engaged state between the slider 31 and the locking member R is released.
- the coupling member 32 is constituted by the horizontal portion 321 and the suspended portion 322 and is shaped such that the coupling member 32 is opened to below. Therefore, even when the routeman performs a locking operation of the key in order to remove the key from the key insertion slot, a downward locking movement of the cylinder lever 33 is allowed in a state where the slider 31 is positioned at the releasing position as shown in FIGS. 11 and 12 .

Abstract
Description
- The present invention relates to a locking device of an automatic vending machine and, more specifically, to a locking device of an automatic vending machine which maintains a state where a door body closes a front opening of an automatic vending machine main body due to an engagement between a locking member arranged on one of the automatic vending machine main body and the door body and a slider arranged on the other of the automatic vending machine main body and the door body, and which allows the door body to perform an opening movement and the front opening of the automatic vending machine main body to be opened due to a release of the engagement between the locking member and the slider.
- Generally, an automatic vending machine includes an automatic vending machine main body which has a cuboid shape with an open front surface and which internally stores products, and a door body arranged so as to be capable of opening and closing the front opening of the automatic vending machine main body. A rectangular opening is formed on the door body, and a slider supported by a supporting member so as to be slidable in a vertical direction between a locking position and a releasing position is arranged on the door body. The slider has an approximately C-shaped transverse section and is provided with a rectangular opening which allows entry by a locking member that is a hook-like metal fixture arranged on the automatic vending machine main body. In addition, a rectangular hole is formed on the slider and a rod (an elongated columnar portion) of a cylinder lever is inserted into the rectangular hole. The cylinder lever is coupled to an inner cylinder of a cylinder lock which is arranged on a front surface of the door body and which has a key insertion slot. The cylinder lever performs an unlocking movement around its own axis in response to an unlocking operation of a key inserted into the key insertion slot and performs a locking movement around its own axis in response to a locking operation of the key. The slider moves from the locking position to the releasing position as the rod abuts an upper edge portion of the rectangular hole due to an unlocking movement of the cylinder lever, and moves from the releasing position to the locking position as the rod abuts a lower edge portion of the rectangular hole due to a locking movement of the cylinder lever.
- In a state where the door body blocks the front opening of the automatic vending machine main body, the locking member enters the rectangular opening of the slider which has descended to the locking position and engages an upper edge portion of the rectangular opening. Subsequently, when an ascending movement of the slider to the releasing position is performed via the cylinder lever due to an unlocking operation of the key, the engagement between the locking member and the slider is released. Therefore, by having the door body perform an opening movement, the front opening of the automatic vending machine main body is opened and restocking of products and the like can be performed. Moreover, the slider having performed an ascending movement to the releasing position is held at the releasing position due to an engagement of a slider holding member with the rectangular opening.
- On the other hand, by causing the door body to perform a closing movement so as to close the front opening of the automatic vending machine main body, the locking member enters the rectangular opening of the slider held at the releasing position by the slider holding member, the locking member presses down the slider holding member to release the engagement by the slider holding member, and the slider automatically moves from the releasing position to the locking position due to the slider's own weight. Accordingly, the upper edge portion of the rectangular opening of the slider and the locking member abut each other and the slider and the locking member engage each other. Due to the engagement between the slider and the locking member in this manner, a state where the door body closes the front opening of the automatic vending machine main body is retained.
- As shown, the slider holding member which holds the slider at a releasing position is equipped with a function for automatically engaging the slider and the locking member with each other by closing the door body to cause the slider to descend to the locking position. Therefore, an inconvenience of performing an unlocking operation of the key when closing the door body to cause the slider to descend and engage the locking member can be eliminated (for example, refer to Patent Document 1).
- Patent Document 1: Japanese Patent Application Laid-open No.
2002-342827 - When a tool that is an elongated rod-like body such as a driver is entered through the rectangular opening of the slider by taking off an anti-theft plate provided on the door body in the event that a state is maintained in which the door body closes the front opening of the automatic vending machine main body, since the slider has an approximately C-shaped transverse section, a tip of the tool unintentionally abuts a slider holding member or a supporting member (hereinafter also referred to as a "slider holding member or the like") and a middle part of the tool abuts an edge portion of the rectangular opening of the slider. In this state, when the tool is swung in, for example, a vertical direction using the tip of the tool as a fulcrum, there is a risk that the slider may separate from the slider holding member or the like due to the principle of leverage and a sliding movement of the slider from the locking position to the releasing position may occur. When a sliding movement of the slider from the locking position to the releasing position occurs in this manner, the engagement between the slider and the locking member is released and the front opening of the automatic vending machine main body can be opened due to the door body performing an opening movement, which is inappropriate.
- Meanwhile, a rectangular hole is formed in the slider and a rod (an elongated columnar portion) of a cylinder lever is inserted into the rectangular hole. The cylinder lever performs an unlocking movement around its own axis in response to an unlocking operation of a key inserted into a key insertion slot arranged on a front surface of the door body and performs a locking movement around its own axis in response to a locking operation of the key. The slider moves from the locking position to the releasing position as the rod abuts an upper edge portion of the rectangular hole due to an unlocking movement of the cylinder lever, and moves from the releasing position to the locking position as the rod abuts a lower edge portion of the rectangular hole due to a locking movement of the cylinder lever.
- Therefore, when a state is maintained in which the door body closes the front opening of the automatic vending machine main body or, in other words, when the slider and the locking member are engaged with each other, due to an unlocking operation of a key inserted into the key insertion slot, the cylinder lever performs an unlocking movement and the slider moves from the locking position to the releasing position. The slider having moved to the releasing position is held by the slider holding member. Once the slider is held at the releasing position, an engaged state with the locking member is released and the front opening of the automatic vending machine main body can now be opened by having the door body perform an opening movement.
- Generally, a key is inserted into the key insertion slot by a routeman who is responsible for restocking products, maintenance, and the like. In addition, with a cylinder lock, a position at which a key is inserted and removed is set to a fixed position (for example, the position of 12 o'clock on a clock). Therefore, when an unlocking operation is performed by inserting a key into the key insertion slot or, in other words, when an unlocking operation is performed by inserting a key into the key insertion slot and turning the key clockwise by 90 degrees, the key cannot be removed in this state. In order to remove the key, a locking operation (which involves turning the key counter-clockwise by 90 degrees to restore the key to the original position) must be performed. However, the slider, to which the cylinder lever is coupled, has ascended to a releasing position due to the unlocking operation and is held by the slider holding member. Therefore, the key cannot be removed from the key insertion slot unless either the door body is closed or the maintained state of the slider by the slider holding member is released. Furthermore, the routeman generally carries the key together with keys of other automatic vending machines on a mounting portion such as a dedicated cord or the like on a belt loop of his/her own uniform.
- Therefore, in order to perform restocking of products, the routeman first inserts a key into the key insertion slot and performs an unlocking operation. Accordingly, the slider moves from the locking position to the releasing position via the cylinder lever and an engagement between the slider and the locking member is released. Consequently, while the front opening of the automatic vending machine main body can be opened by having the door body perform an opening operation, since the key is attached to the routeman's own uniform via a mounting member such as a cord as described above, the key must be removed from the key insertion slot in order to perform restocking of products or the like. In order to do so, after releasing the held state of the slider at the releasing position by the slider holding member, a locking operation of the key is performed in order to remove the key from the key insertion slot. Since a locking operation is performed to remove the key from the key insertion slot in this manner, the slider has made a sliding movement from the releasing position to the locking position via the cylinder lever. While the front opening of the automatic vending machine main body must be closed by having the door body perform a closing operation after the restocking of products or the like, a locking operation has been performed in order to remove the key from the key insertion slot and the slider has moved to the locking position. Therefore, since the locking member is unable to enter the rectangular opening of the slider even if a closing movement is performed as-is by the door body, the routeman must once again insert the key into the key insertion slot and perform an unlocking operation, move the slider from the locking position to the releasing position, and while maintaining this state, have the door body perform a closing movement to close the front opening of the automatic vending machine main body and have the slider and the locking member engage each other in order to remove the key from the key insertion slot.
- As shown, when performing restocking of products or the like, closing the front opening of the automatic vending machine main body by having the door body perform a closing operation after opening the front opening of the automatic vending machine main body by having the door body perform an opening operation requires that the key is once again inserted into the key insertion slot to perform an unlocking operation, making servicing such as restocking of products a hassle. Aside from the above, there are always demands for locking devices which maintain a state where the door body closes the front opening of the automatic vending machine main body and which have superior anti-theft performance.
- The present invention has been made in consideration of the above circumstances, and an object thereof is to provide a locking device of an automatic vending machine which is capable of preventing a slider from moving from a locking position to a releasing position even if an elongated rod-like body such as a tool is entered through a rectangular opening.
- In addition, in consideration of the above circumstances, another object of the present invention is to provide a locking device of an automatic vending machine which is capable of securing favorable anti-theft performance while improving efficiency of servicing such as restocking of products.

Therefore, even if the rod-like body is swung with its tip as a fulcrum, only the slider deforms due to the principle of leverage and there is no risk of the slider separating from the slider holding member or the like and performing a sliding movement from the locking position to the releasing position. As a result, an advantageous effect is achieved in that the slider can be prevented from moving from the locking position to the releasing position.
- In addition, according to the present invention, a coupling member integrally arranged with the slider is displaced by being abutted by the cylinder lever and moves the slider from the locking position to the releasing position when the cylinder lever performs an unlocking movement and constantly allows a locking movement by the cylinder lever when the cylinder lever performs a locking movement. Therefore, when a closing movement of the door body is performed after performing servicing such as restocking of products, there is no longer a need to once again insert a key into the key insertion slot and servicing such as restocking of products becomes hassle-free. Furthermore, since a restricting member normally restricts displacement of the coupling member and suppresses movement of the slider from the locking position to the releasing position and allows displacement of the coupling member when the cylinder lever performs an unlocking movement, anti-theft performance can be secured when a state is maintained where the door body closes the front opening of the automatic vending machine main body. As a result, an advantageous effect is achieved in that anti-theft performance can be favorably secured while improving efficiency of servicing such as restocking of products.

FIG. 1 is a perspective view showing an internal structure of an automatic vending machine to which a locking device according to an embodiment of the present invention has been applied. The automatic vending machine exemplified here is for sales of a product that is a canned beverage, a beverage in a plastic bottle, a beverage in a carton, or the like in a refrigerated or heated state, and includes amain body cabinet 1 that is an automatic vending machine main body. - The
main body cabinet 1 is shaped as a cuboid with an open front surface. An interior of themain body cabinet 1 is partitioned into halves, with an upper half constituting aproduct storage chamber 2 and a lower half constituting amachine room 3. Theproduct storage chamber 2 is a chamber having an interior kept at a preset temperature condition, and wall members constituting theproduct storage chamber 2 are respectively formed of insulating material. In addition, although not shown in the drawing, cooling means for cooling internal atmosphere such as an evaporator that constitutes a refrigeration cycle and heating means for heating the internal atmosphere such as an electrical heater are provided. - Although details will be omitted, the
product storage chamber 2 described above is provided with aproduct rack 4 and bucket driving means 5. Theproduct rack 4 is constituted by juxtaposing a plurality of product storage columns in a horizontal direction, wherein each product storage column is capable of storing a plurality of products aligned in a front-back direction in a product storage passage that is demarcated in each product storage column. A plurality of theseproduct racks 4 is provided in a vertical direction so as to bridge between rack supporting side plates (not shown) which are mounted to theproduct storage chamber 2 as a left and right pair. Moreover, in the present specification, a left side indicates leftward when the automatic vending machine is viewed from front, and a right side indicates rightward when the automatic vending machine is viewed from front. - The bucket driving means 5 is configured as an assembly of an x-axis conveying mechanism and a y-axis conveying mechanism. The x-axis conveying mechanism includes a rail member that extends in a horizontal direction in an area in front of the
product rack 4 inside themain body cabinet 1, and moves a mounted bucket in a direction in which the rail member extends (the horizontal direction) due to driving of an x-axis motor. - The y-axis conveying mechanism is provided on a pair of left and right conveyance support frames. A pulley is rotatably arranged in a vicinity of an upper end portion of the conveyance support frames. A belt that is an elongated cord-like body is wound around the pulley. A waiter is connected to one end of the belt and a holding member for holding the rail member is connected to another end of the belt. As the pulley rotates due to driving by a y-axis motor, the y-axis conveying mechanism moves the rail member held by the holding member and the x-axis conveying mechanism mounted with a bucket in a vertical direction.
- A refrigerator (a compressor and a condenser) that constitutes a refrigeration cycle together with the evaporator and various control devices are provided in the
machine room 3. - An
inner door 10 and an outer door (door body) 20 are provided on the front surface of themain body cabinet 1. Theinner door 10 is formed by inlaying a transparent plate material such as insulated glass and is large enough to cover the front surface of theproduct storage chamber 2. When theinner door 10 performs a closing movement and blocks the front surface of theproduct storage chamber 2, theinner door 10 becomes an insulating member that constitutes the front surface of theproduct storage chamber 2. - A rectangular
product discharge port 11 is formed and adischarge flapper 12 for opening and closing theproduct discharge port 11 is provided in a lower area on a right-hand side of a central portion of the transparent plate of theinner door 10. Thedischarge flapper 12 is axially supported so as to be swingable in a front-back direction with its lower end being a free end, and normally closes theproduct discharge port 11 due to its own weight. - The
outer door 20 is for opening and closing the front opening of themain body cabinet 1 and is constituted using an insulating material as necessary, and includes awindow 21 made by inlaying a transparent plate such as insulated glass. Therefore, the automatic vending machine being described is a so-called glass-front vending machine with its interior viewable through thewindow 21 of theouter door 20. In addition, although not shown, arranged on the front surface of theouter door 20 are components necessary for automatic sales of products such as a selection switch for selecting sold products and a coin acceptor into which coins are inserted. - A locking member R and a slider 31 (refer to
FIG. 2 ) which constitute a locking device are respectively arranged on themain body cabinet 1 and theouter door 20. As shown inFIG. 1 , the locking member R is arranged at a predetermined location at a front end on a right-hand side of themain body cabinet 1. The locking member R is conventionally known and is a metal fixture shaped like a hook. Theslider 31 is arranged inside apocket portion 22 formed at an open end of theouter door 20.Reference numeral 23 inFIG. 1 denotes an opening of thepocket portion 22 which is formed at a same height level as the locking member R and which allows entry of the locking member R. -
FIG. 2 is a perspective view showing substantial parts that constitute the locking device including theslider 31 arranged inside thepocket portion 22 of theouter door 20 shown inFIG. 1 .FIG. 3 is a perspective view schematically showing an enlargement of the substantial parts of the locking device shown inFIG. 2 .FIG. 4 is an exploded perspective view which shows a breakdown of theslider 31 shown inFIG. 2 and which is a view from an opposite side toFIGS. 2 and3 .FIG. 5 is an enlarged plan view showing a case where theslider 31 shown inFIG. 2 is viewed from above. As exemplified inFIGS 2 to 5 , the locking device is configured so as to include acoupling member 32, acylinder lever 33, and a restrictingmember 34 in addition to theslider 31. - The
slider 31 is formed by appropriately bending a plate material such as a steel plate and has an approximately C-shaped transverse section. A rectangular opening (hereinafter also referred to as a slider opening) 3111 is formed at a position in abase portion 311 corresponding to theopening 23 of thepocket portion 22. Along hole 3121 whose longitudinal direction is a vertical direction is formed above bothend side portions 312 of theslider 31. Theslider 31 is arranged so as to be slidable in a vertical direction in a state where theslider 31 has entered into a slider supporting piece (supporting member) 35 which has a C-shaped transverse section and which is fastened to thepocket portion 22 of theouter door 20. More specifically, a throughhole 3511 is formed in bothside portions 351 of theslider supporting piece 35 and, due to a slider pin member (not shown) being inserted into the throughhole 3511 and thelong hole 3121, theslider 31 is arranged so as to be slidable in a vertical direction. In this case, a position where the slider pin member and a lower edge portion of thelong hole 3121 abut each other is an upper limit position of upward movement of theslider 31, and a position where the slider pin member and an upper edge portion of thelong hole 3121 abut each other is a lower limit position of downward movement of theslider 31. The upper limit position is a releasing position and the lower limit position is a locking position. In other words, theslider 31 is arranged so as to be movable between the locking position and the releasing position. - A
slider holding member 36 is axially supported inside theslider 31 described above so as to be swingable around an axis of the slider pin member while being inserted by the slider pin member. Theslider holding member 36 is formed by appropriately bending a plate material such as a steel plate and has an approximately C-shaped transverse section. Alatch portion 3611 that protrudes toward thebase portion 311 of the slider 31 (a rear surface-side of the outer door 20) is formed on a downward-extending end portion of theside portion 361 positioned on the open end-side of theouter door 20, and is constantly biased toward thebase portion 311 of theslider 31 by a spring member B constituted by a coil spring wound around the slider pin member. - With the
slider holding member 36 described above, when theslider 31 performs an upward sliding movement and is positioned at the upper limit position or, in other words, the releasing position, thelatch portion 3611 protrudes from theslider opening 3111 and engages with an upper edge portion of theslider opening 3111, and theslider holding member 36 holds theslider 31 in a state where theslider 31 is positioned at the releasing position. - On the other hand, although the locking member R arranged in the
main body cabinet 1 passes through theopening 23 of thepocket portion 22 and then enters into theslider 31 through theslider opening 3111 when the front opening of themain body cabinet 1 is closed by a closing movement of theouter door 20, theslider holding member 36 swings against a biasing force of the spring member B so as to separate from thebase portion 311 of theslider 31 due to the locking member R having entered inside abutting an abuttingportion 3621 formed at abase portion 362 of theslider holding member 36. When theslider holding member 36 swings so as to separate from thebase portion 311 of theslider 31 in this manner, the engagement between thelatch portion 3611 and the upper edge portion of theslider opening 3111 is released and theslider 31 performs a downward sliding movement due to its own weight and reaches the lower limit position or, in other words, the locking position. Accordingly, the upper edge portion of theslider opening 3111 and the locking member R abut each other and theslider 31 engages with the locking member R at the locking position. - With the
slider 31 described above, anabutting piece 3122 is integrally formed by welding at a predetermined location of an extended end portion of theside portion 312 positioned on an opposite side to the open end of theouter door 20 or, in other words, a location with approximately a same height level as theslider holding member 36. Theabutting piece 3122 is provided so as to extend from the extended end portion of theside portion 312 toward theside portion 312 on the open end side. In addition, in thebase portion 362 of theslider holding member 36, a notchedportion 3622 is formed in an area on an opposite side to the open end of theouter door 20 or, in other words, an area opposing theabutting piece 3122. - The
coupling member 32 is formed by appropriately bending a plate material such as a steel plate and is integrally formed at a lower end portion of theslider 31 so as to protrude in an opposite direction to the open end of theouter door 20. As shown inFIG. 6 , thiscoupling member 32 has ahorizontal portion 321 that extends in a horizontal direction and a suspendedportion 322 that extends downward from an end portion of thehorizontal portion 321. Ahook portion 323 is formed at an extended end portion of the suspendedportion 322. - The
cylinder lever 33 is axially supported so as to be swingable around an axis of its own shaft portion by an inner cylinder of a key cylinder which rotationally moves in accordance with a locking operation and an unlocking operation of a key inserted into a key insertion slot (not shown) provided on a front surface of the outer door 20 (an outer cylinder of the key cylinder is fastened to a frame member of the outer door 20). More specifically, thecylinder lever 33 performs an upward unlocking movement due to an unlocking operation of the key inserted into the key insertion slot and performs a downward locking movement due to a locking operation of the key. Thecylinder lever 33 has an elliptically-shapedportion 331, and arod member 332 is provided so as to protrude toward the suspendedportion 322 of thecoupling member 32 at a portion other than a shaft portion of the elliptically-shapedportion 331. Therod member 332 is positioned in an area below thehorizontal portion 321 of thecoupling member 32. - The restricting
member 34 is formed by appropriately bending a plate material such as a steel plate and is arranged on a frame member of theouter door 20 via a restrictingpin member 37 so as to be swingable around its own axis that is consistent with a central axis of the restrictingpin member 37. Agroove portion 341 opened to below and aweight portion 342 are respectively formed on the restrictingmember 34, and the restrictingmember 34 is positioned at a restricting position due to theweight portion 342 as shown inFIG. 3 . When the restrictingmember 34 is positioned at the restricting position, entry by thehook portion 323 of thecoupling member 32 into thegroove portion 341 is allowed. In other words, when the restrictingmember 34 is positioned at the restricting position, thegroove portion 341 is positioned in an area above thehook portion 323. - A guiding
member 38 is interposed between the restrictingmember 34 and thecylinder lever 33. The guidingmember 38 is coupled to the restrictingmember 34. When thecylinder lever 33 performs an unlocking movement, the guidingmember 38 is abutted against a part of a peripheral edge portion of the elliptically-shapedportion 331 of thecylinder lever 33 and, as shown inFIG. 7 , swings the restrictingmember 34 positioned at the restricting position upward against a force of gravity of theweight portion 342 and moves the restrictingmember 34 to the allowing position. In this case, when thecylinder lever 33 performs an unlocking movement, an adjustment is made in advance so that a part of the peripheral edge portion of the elliptically-shapedportion 331 of thecylinder lever 33 abuts the guidingmember 38 before therod member 332 of thecylinder lever 33 abuts a lower surface of thehorizontal portion 321 of thecoupling member 32. Accordingly, the restrictingmember 34 is positioned at the allowing position before therod member 332 of thecylinder lever 33 abuts thehorizontal portion 321 of thecoupling member 32 and, as a result, thehook portion 323 of thecoupling member 32 disengages from thegroove portion 341 of the restrictingmember 34. - With an automatic vending machine to which a locking device configured as described above is applied, servicing such as restocking of products with respect to the inside of the
main body cabinet 1 can be performed as follows. - First, a case where the locking device maintains a state where the
outer door 20 closes the front opening of themain body cabinet 1 will be described. In this case, theslider 31 constituting the locking device is positioned at the locking position and is in engagement with the locking member R, and the restrictingmember 34 is positioned at the restricting position. - In such a case, when an anti-theft plate 24 (refer to
FIG. 5 ) of theouter door 20 is taken off by a mindless third party attempting to cause an upward sliding movement of theslider 31 positioned at the locking position by inserting a foreign object into theslider opening 3111 of theslider 31, as shown inFIG. 8 , thehook portion 323 of thecoupling member 32 integrally formed with theslider 31 abuts the restrictingmember 34 positioned at the restricting position and restricts further upward sliding movement of theslider 31. - In addition, when a key is inserted into the key insertion slot of the automatic vending machine by a routeman performing servicing such as restocking of products and an unlocking operation of the key is performed, the
cylinder lever 33 performs an upward unlocking movement as shown inFIG. 7 . Due to the guidingmember 38 being abutted by a part of the peripheral edge portion of thecylinder lever 33 in the process of unlocking, the restrictingmember 34 swings from the restricting position toward the allowing position against a force of gravity of theweight portion 342. Accordingly, thehook portion 323 of thecoupling member 32 disengages from thegroove portion 341 of the restrictingmember 34. In other words, when the restrictingmember 34 is positioned at the restricting position, the restrictingmember 34 restricts upward displacement of thecoupling member 32 and suppresses a sliding movement of theslider 31 from the locking position to the releasing position, and when the restrictingmember 34 is positioned at the allowing position, the restrictingmember 34 allows displacement of thecoupling member 32. - Subsequently, as shown in
FIGS. 9 and10 , as a result of the lower surface of thehorizontal portion 321 of thecoupling member 32 being abutted by therod member 332 of thecylinder lever 33 performing an unlocking movement and thecoupling member 32 displaced upward by being pressed by therod member 332, theslider 31 with which thecoupling member 32 is integrally formed also performs a sliding movement from the locking position to the releasing position. - When the
slider 31 performs an upward sliding movement as described above and is positioned at the releasing position, thelatch portion 3611 of theslider holding member 36 protrudes from theslider opening 3111 toward the rear surface side and engages with the upper edge portion of theslider opening 3111, and holds theslider 31 in a state where theslider 31 is positioned at the releasing position. When theslider 31 is held at the releasing position in this manner, an engaged state between theslider 31 and the locking member R is released. - As described earlier, the
coupling member 32 is constituted by thehorizontal portion 321 and the suspendedportion 322 and is shaped such that thecoupling member 32 is opened to below. Therefore, even when the routeman performs a locking operation of the key in order to remove the key from the key insertion slot, a downward locking movement of thecylinder lever 33 is allowed in a state where theslider 31 is positioned at the releasing position as shown inFIGS. 11 and12 . - In other words, the
coupling member 32 is integrally arranged with theslider 31. When thecylinder lever 33 performs an unlocking movement, thecoupling member 32 is displaced due to being abutted by thecylinder lever 33 and moves theslider 31 from the locking position to the releasing position, and when thecylinder lever 33 performs a locking movement, thecoupling member 32 constantly allows the locking movement. - As described above, since the
coupling member 32 constantly allows the locking movement of thecylinder lever 33, the routeman is able to open the front opening of themain body cabinet 1 by performing an opening movement of theouter door 20 after removing the key from the key insertion slot, and can subsequently perform servicing such as restocking of products by performing an opening movement of theinner door 10. - In this case, even when the
cylinder lever 33 has performed a locking movement, the restrictingmember 34 is positioned at the allowing position due to being abutted by a tip of thehook portion 323 of thecoupling member 32 that is integrally formed with theslider 31 positioned at the releasing position. - After performing servicing such as restocking of products, when the routeman performs a closing movement of the
outer door 20 to close the front opening of themain body cabinet 1, the locking member R of themain body cabinet 1 enters theslider 31 through theslider opening 3111 and abuts the abuttingportion 3621 formed on thebase portion 362 of theslider holding member 36. Accordingly, theslider holding member 36 swings so as to separate from thebase portion 311 of theslider 31 and the engagement between thelatch portion 3611 and the upper edge portion of theslider opening 3111 is released. Theslider 31 performs a downward sliding movement due to its own weight and reaches the lower limit position or, in other words, the locking position, the upper edge portion of theslider opening 3111 and the locking member R abut each other, theslider 31 engages with the locking member R at the locking position and, as a result, a state where theouter door 20 closes the front opening of themain body cabinet 1 can be maintained. In other words, when a closing movement of theouter door 20 is performed to close the front opening of themain body cabinet 1 after performing servicing such as restocking of products, there is no longer a need to perform an unlocking operation or the like by once again inserting the key into the key insertion slot as was conventional. - Meanwhile, with the
slider 31 of the locking device described above, the abuttingpiece 3122 is integrally formed at an extended end portion of one side portion 312 (theside portion 312 positioned on an opposite side to the open end of the outer door 20), and the notchedportion 3622 is formed in an area opposing theabutting piece 3122 among thebase portion 362 of theslider holding member 36. - Accordingly, when a state is maintained in which the
outer door 20 closes the front opening of themain body cabinet 1, for example, even if theanti-theft plate 24 provided on theouter door 20 is taken off by a mindless third party and a tool K that is an elongated rod-like body such as a driver is entered through theslider opening 3111, a tip of the tool K can be abutted against the abuttingpiece 3122 as shown inFIG. 13 . Therefore, both the tip and a middle part of the tool K abut theslider 31 that is a same member, and even if the tool K is swung with its tip as a fulcrum in, for example, a vertical direction, only theslider 31 deforms due to the principle of leverage and there is no risk of theslider 31 separating from theslider holding member 36 or the like and performing a sliding movement from the locking position to the releasing position. - As described above, with the locking device of an automatic vending machine according to the present invention, when the
cylinder lever 33 performs an unlocking movement, thecoupling member 32 is displaced by being abutted by thecylinder lever 33 and moves theslider 31 from the locking position to the releasing position, and when thecylinder lever 33 performs a locking movement, thecoupling member 32 constantly allows the locking movement by the cylinder lever. Therefore, when a closing movement of theouter door 20 is performed after performing servicing such as restocking of products, there is no longer a need to once again insert a key into the key insertion slot and servicing such as restocking of products becomes hassle-free. In addition, when the restrictingmember 34 is positioned at the restricting position, the restrictingmember 34 restricts upward displacement of thecoupling member 32 and suppresses a sliding movement of theslider 31 from the locking position to the releasing position, and when the restrictingmember 34 is positioned at the allowing position, the restrictingmember 34 allows displacement of thecoupling member 32. Therefore, anti-theft performance may be secured when a state is maintained where theouter door 20 closes the front opening of themain body cabinet 1. Consequently, anti-theft performance can be favorably secured while improving efficiency of servicing such as restocking of products. - Furthermore, according to the locking device described above, even if the tool K or the like is entered through the
slider opening 3111, since the tip of the tool K or the like abuts theabutting piece 3122 integrally formed with theslider 31, there is no risk of theslider 31 separating from theslider holding member 36 or the like and performing a sliding movement from the locking position to the releasing position. Accordingly, theslider 31 can be prevented from moving from the locking position to the releasing position. - As described above, the locking device of an automatic vending machine according to the present invention is useful for maintaining a state where an outer door closes a front opening of an automatic vending machine main body.
