[0012] A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings. The dimensions, materials, and other specific values ​​shown in the embodiment are merely examples for facilitating understanding of the invention, and do not limit the present invention unless otherwise specified. In this specification and drawings, elements having substantially the same functions and configurations are given the same reference numerals to avoid repeated explanations, and elements not directly related to the present invention are not shown.

[0013] Fig. 1 is a perspective view showing an open state of a gaming machine main body 1 in this embodiment. As shown in Fig. 1, the gaming machine main body 1 includes an outer frame 3 in which an enclosed space is formed by four sides assembled in a substantially rectangular shape, a middle door 5 pivotally supported by the outer frame 3 via a hinge so as to be freely opened and closed and holding a game board (not shown), and a front door 9 pivotally supported by the outer frame 3 via a hinge so as to be freely opened and closed like the middle door 5 and holding a glass or resin transparent plate 7. In the following description, the LR direction in the figure is the width direction of the gaming machine main body 1, the F direction in the figure is the front side or front side of the gaming machine main body 1, and the B direction in the figure is the back side of the gaming machine main body 1.

[0014] In this embodiment, since a hinge mechanism is provided at the end of the gaming machine main body 1 in the direction of the arrow L, the end in the direction of the arrow R, i.e., the right end when viewed from the front of the gaming machine main body 1, becomes the free end. When the middle door 5 and the front door 9 are closed against the outer frame 3, the outer frame 3, the middle door 5 and the front door 9 become parallel, and the gaming board and the transparent plate 7 face each other parallel while maintaining a predetermined distance.

[0015] In addition, the middle door 5 and the front door 9 can be opened and closed independently of the outer frame 3. The middle door 5 has a smaller circumference than the outer frame 3 and the front door 9. When the middle door 5 and the front door 9 are closed against the outer frame 3, the middle door 5 is contained within the outer frame 3 and the front door 9, and the middle door 5 cannot be seen from the outside.

[0016] 1, a cylinder lock 11 with a keyhole 11a opening on the front side of the gaming machine main body 1 is provided on the free end side of the middle door 5, and when the middle door 5 and the front door 9 are closed to the outer frame 3, a key is inserted into the keyhole 11a to perform an unlocking operation, thereby unlocking the middle door 5 and the front door 9 from the outer frame 3. The middle door 5 is provided with a decorative unit D that covers the periphery of the cylinder lock 11, and the front door 9 has a cutout 9a formed in a portion facing the decorative unit D.

[0017] FIG. 2 is a front view showing a state in which the middle door 5 is closed by the outer frame 3, and FIG. 3 is a front view of the gaming machine main body 1. As shown in FIG. 2, the gaming machine main body 1 is provided with a locking device 21. The locking device 21 has the above-mentioned cylinder lock 11 and a locking unit 31. The locking unit 31 is provided on the open side surface portion 5a located on the free end side of the middle door 5. The locking unit 31 is displaced to a locked state that restricts the opening of the middle door 5 and the front door 9 relative to the outer frame 3, or to an unlocked state that allows the middle door 5 and the front door 9 to be opened relative to the outer frame 3. As will be described in detail later, the locking unit 31 is displaced from the locked state to the unlocked state in conjunction with the unlocking operation of the key inserted into the keyhole 11a of the cylinder lock 11. The cylinder lock 11 is screwed to the locking unit 31.

[0018] The decorative unit D is provided on the front side of the gaming machine main body 1 relative to the lock unit 31, and covers the screw-fastened portion between the cylinder lock 11 and the lock unit 31. Then, as shown in FIG. 3, when the middle door 5 and the front door 9 are closed relative to the outer frame 3, the decorative unit D provided on the middle door 5 and the key hole 11a of the cylinder lock 11 are exposed to the front side from the notch 9a of the front door 9. This allows the middle door 5 or the front door 9 to be opened relative to the outer frame 3 by inserting a key into the key hole 11a from the front side of the gaming machine main body 1 to perform an unlocking operation.

[0019] Fig. 4 is a perspective view of the locking device 21. Fig. 5 is a front view of the locking device 21. Fig. 6 is an exploded perspective view of the locking device 21. Fig. 7 is a partially enlarged perspective view of the locking device 21. Figs. 4 to 7 show the locking device in a locked state.

[0020] As described above, the locking device 21 has the cylinder lock 11 and the lock unit 31. The lock unit 31 includes a base member 32, a first slide member 33, a second slide member 34, and a cover member 35. Note that in Fig. 7, the cover member 35 is omitted.

[0021] The base member 32 is a plate extending in the vertical direction. The base member 32 is fixed to the open side surface portion 5a. The first slide member 33 and the second slide member 34 are plates extending in the vertical direction and parallel to the base member 32. The first slide member 33 and the second slide member 34 are stacked on the side surface of the base member 32. Specifically, going from the inside to the outside of the gaming machine main body 1, the open side surface portion 5a, the base member 32, the first slide member 33, and the second slide member 34 are stacked in this order. The cover member 35 is placed further outside the second slide member 34.

[0022] The first slide member 33 and the second slide member 34 are supported so as to be slidable in the vertical direction relative to the base member 32. The first slide member 33 and the second slide member 34 are supported by the base member 32 so as to be movable (movable) independently of each other.

[0023] A cylinder fixing surface 32a for fixing the cylinder lock 11 is provided protruding from the base member 32. The side of the cylinder lock 11 opposite to the keyhole 11a is fixed to the cylinder fixing surface 32a by a screw.

[0024] In addition, the base member 32 is provided with a guide pillar 32b that protrudes toward the first slide member 33 and the second slide member 34. The guide pillar 32b is formed, for example, in a cylindrical shape.

[0025] A cam 41 is connected to the cylinder lock 11. The cam 41 rotates in conjunction with an unlocking operation of a key inserted into a keyhole 11a of the cylinder lock 11. A first arm 42a and a second arm 42b are formed on the cam 41. Of the first arm 42a and the second arm 42b, the first arm 42a is positioned relatively vertically downward, and the second arm 42b is positioned relatively vertically upward. The first arm 42a protrudes obliquely downward from the cam 41. The second arm 42b protrudes obliquely upward from the cam 41. The first arm 42a and the second arm 42b are inserted into an opening 43 formed in the base member 32.

[0026] 5 illustrates the initial position (initial posture) of the key inserted into the cylinder lock 11. In other words, the initial position for unlocking is when the key is roughly parallel to the vertical plane. When the key is in the initial position, both the middle door 5 and the front door 9 are locked.

[0027] There are two ways to unlock the gaming machine main body 1: a first unlocking operation in which the key inserted in the keyhole 11a is rotated counterclockwise (left rotation) as shown by the arrow 46a in Fig. 5, and a second unlocking operation in which the key inserted in the keyhole 11a is rotated clockwise (right rotation) as shown by the arrow 46b in Fig. 5. The cam 41 rotates left in conjunction with the left rotation of the key (first unlocking operation), and rotates right in conjunction with the right rotation of the key (second unlocking operation). In other words, the first arm 42a rises approximately vertically upward in conjunction with the left rotation of the key, and the second arm 42b descends approximately vertically downward in conjunction with the right rotation of the key.

[0028] The first slide member 33 is provided with a hook portion 51 that protrudes further toward the front side of the gaming machine main body 1 than the base member 32. The hook portion 51 can be locked to a locking portion provided on the back surface of the front door 9. When the hook portion 51 is locked to the locking portion, the front door 9 is restricted from opening relative to the inner door 5. When the key is in the initial position, the hook portion 51 is locked to the locking portion, and the front door 9 is locked.

[0029] Further, the first slide member 33 is formed with a first arm opening 52a and a second arm opening 52b. The first arm opening 52a and the second arm opening 52b are arranged so that at least a portion of each of them overlaps with the opening 43 of the base member 32. Of the first arm opening 52a and the second arm opening 52b, the first arm opening 52a is located relatively vertically downward, and the second arm opening 52b is located relatively vertically upward. The first arm 42a that passes through the opening 43 is inserted into the first arm opening 52a. The second arm 42b that passes through the opening 43 is inserted into the second arm opening 52b.

[0030] Further, a guide hole 53 is formed in the first slide member 33. The guide hole 53 is formed in a rectangular or elliptical shape that is elongated in the vertical direction. The guide pillar 32b of the base member 32 is inserted into the guide hole 53. The guide hole 53 and the guide pillar 32b regulate the sliding direction of the first slide member 33 in the vertical direction.

[0031] The second slide member 34 is provided with a hook portion 61 that protrudes further toward the rear side of the gaming machine main body 1 than the base member 32. The hook portion 61 can be locked to a locking portion provided on the front surface of the outer frame 3. When the hook portion 61 is locked to the locking portion, the inner door 5 is restricted from being opened relative to the outer frame 3. When the key is in the initial position, the hook portion 61 is locked to the locking portion, and the inner door 5 is locked.

[0032] Further, a first arm opening 62a and a second arm opening 62b are formed in the second slide member 34. The first arm opening 62a and the second arm opening 62b are arranged so that at least a portion of each of them overlaps with the opening 43 of the base member 32. The first arm opening 62a is disposed so as to overlap at least a portion of the first arm opening 52a of the first slide member 33. The second arm opening 62b is disposed so as to overlap at least a portion of the second arm opening 52b of the first slide member 33. Of the first arm opening 62a and the second arm opening 62b, the first arm opening 62a is positioned relatively vertically downward, and the second arm opening 62b is positioned relatively vertically upward. The first arm 42a is inserted through the opening 43 and the first arm opening 52a. The second arm 42b is inserted through the opening 43 and the second arm opening 52b.

[0033] Further, a guide hole 63 is formed in the second slide member 34. The guide hole 63 is formed in a rectangular or elliptical shape that is elongated in the vertical direction. The guide pillar 32b of the base member 32 is inserted into the guide hole 63. The guide hole 63 and the guide pillar 32b regulate the sliding direction of the second slide member 34 in the vertical direction.

[0034] In addition, the first slide member 33 is provided with a first suspension portion 54, and the second slide member 34 is provided with a second suspension portion 64. The first suspension portion 54 and the second suspension portion 64 are provided so as to be shifted from each other in the vertical direction. A biasing portion 65 is provided between the first suspension portion 54 and the second suspension portion 64.

[0035] Specifically, the biasing portion 65 is a coil spring. The biasing portion 65 biases in a direction that eliminates the relative vertical misalignment between the first slide member 33 and the second slide member 34. In other words, when the key is in the initial position (when in the locked state), the biasing force of the biasing portion 65 suppresses the relative vertical misalignment between the first slide member 33 and the second slide member 34.

[0036] As described above, when the key inserted into the cylinder lock 11 is turned left, the first arm 42a rises. Then, the first arm 42a gets caught on the upper end of the first arm opening 52a of the first slide member 33, and moves (slides) the first slide member 33 vertically upward against the biasing force of the biasing portion 65.

[0037] Fig. 8 is a perspective view of the locking device 21 when the key is turned to the left. Fig. 9 is a partially enlarged perspective view of the locking device 21 when the key is turned to the left. In Fig. 8, the cover member 35 is omitted. In Fig. 9, only the members related to the left rotation are shown.

[0038] 8 and 9, when the first slide member 33 is moved vertically upward, the hook portion 51 is moved vertically upward. Then, the hook portion 51 is released from the locking portion of the front door 9, and the front door 9 is unlocked from the inner door 5. In other words, the first slide member 33 is involved in unlocking the front door 9.

[0039] The first arm opening 62a of the second slide member 34 is opened so that the first arm 42a is not caught when the key is turned left. In other words, at this time, the position of the second slide member 34 is maintained, and the inner door 5 relative to the outer frame 3 is not unlocked.

[0040] In contrast, as described above, when the key inserted into the cylinder lock 11 is turned to the right, the second arm descends. Then, the second arm 42b is caught on the lower end of the second arm opening 52b of the second slide member 34, and moves (slides) the second slide member 34 vertically downward against the biasing force of the biasing portion 65.

[0041] Fig. 10 is a perspective view of the locking device 21 when the key is turned to the right. Fig. 11 is a partially enlarged perspective view of the locking device 21 when the key is turned to the right. In Fig. 10, the cover member 35 is omitted. In Fig. 11, only the members related to the right rotation are shown.

[0042] 10 and 11, when the second slide member 34 is moved vertically downward, the hook portion 61 is moved vertically downward. Then, the hook portion 61 is disengaged from the locking portion of the outer frame 3, and the inner door 5 is unlocked relative to the outer frame 3. In other words, the second slide member 34 is involved in unlocking the inner door.

[0043] The second arm opening 52b of the first slide member 33 is opened so that the second arm 42b is not caught when the key is turned to the right. In other words, at this time, the position of the first slide member 33 is maintained, and the front door 9 is not unlocked relative to the middle door 5.

[0044] Returning to Figs. 4 to 7, the first arm opening 52a is provided such that a predetermined first clearance (gap) is formed between the first arm 42a and the upper end of the first arm opening 52a when the key (in other words, the cam 41) is in the initial position. The second arm opening 62b is provided such that a predetermined second clearance (gap) is formed between the second arm 42b and the lower end of the second arm opening 62b when the key (in other words, the cam 41) is in the initial position. As will be described later, the first arm opening 52a and the second arm opening 62b are provided such that a magnitude relationship is generated between the first clearance and the second clearance.

[0045] Furthermore, the locking portion of the front door 9 (locking portion that locks the hook portion 51) is provided so that the distance between the hook portion 51 and the locking portion of the front door 9 when the key is in the initial position is a predetermined first distance. Furthermore, the locking portion of the outer frame 3 (locking portion that locks the hook portion 61) is provided so that the distance between the hook portion 61 and the locking portion of the outer frame 3 when the key is in the initial position is a predetermined second distance. As will be described later, the locking portion of the front door 9 and the locking portion of the outer frame 3 are provided so that a magnitude relationship occurs between the first distance and the second distance.

[0046] The lock unit 31 further includes a first lock lever 71, a first lock lever spring 72, a first unlock lever 73, a first unlock lever spring 74, a second lock lever 81, a second lock lever spring 82, a second unlock lever 83, a second unlock lever spring 84, an auxiliary plate 85, and an auxiliary leaf spring 86. These are disposed between the second slide member 34 and the cover member 35.

[0047] The first lock lever 71 is capable of swinging about a shaft portion connected to the cover member 35. The first lock lever 71 is capable of engaging with the first slide member 33 after moving vertically upward. When the first lock lever 71 engages with the first slide member 33, the first lock lever spring 72 maintains the engaged state. This allows the first slide member 33 to be held (locked) in the unlocked state. For example, a claw-shaped engaging portion is formed on the first lock lever 71, and a protrusion is provided on the side surface of the first slide member 33. The engaging portion of the first lock lever 71 is hooked onto the protrusion of the first slide member 33, and the first lock lever spring 72 maintains the hooking state.

[0048] The first lock release lever 73 is capable of swinging about a shaft portion connected to the cover member 35. The first lock release lever 73 is capable of releasing the engagement between the first lock lever 71 and the first slide member 33 in response to the swinging. For example, the first lock release lever 73 swings the first lock lever 71 against the first lock lever spring 72 when swinging from the initial state. This allows the first slide member 33, which is held (locked) in the unlocked state, to be returned to the locked state. In addition, the first lock release lever spring 74 biases the first lock release lever 73 so as to return the first lock release lever 73 to the initial state.

[0049] The second lock lever 81 is capable of swinging about a shaft portion connected to the cover member 35. The second lock lever 81 is capable of engaging with the second slide member 34 after moving vertically downward. When the second lock lever 81 engages with the second slide member 34, the second lock lever spring 82 maintains the engaged state. This allows the second slide member 34 to be held (locked) in the unlocked state. For example, a claw-shaped engaging portion is formed on the second lock lever 81, and a protrusion is provided on the side surface of the second slide member 34. The engaging portion of the second lock lever 81 is hooked onto the protrusion of the second slide member 34, and the hooking is maintained by the second lock lever spring 82.

[0050] The second lock release lever 83 is capable of swinging about a shaft portion connected to the cover member 35. The second lock release lever 83 is capable of releasing the engagement between the second lock lever 81 and the second slide member 34 in response to the swinging. For example, the second lock release lever 83 swings the second lock lever 81 against the second lock lever spring 82 when swinging from the initial state. This allows the second slide member 34, which is held (locked) in the unlocked state, to be returned to the locked state. In addition, the second lock release lever spring 84 biases the second lock release lever 83 so as to return the second lock release lever 83 to the initial state.

[0051] The auxiliary plate 85 extends from the first lock lever 71 to the second lock lever 81. The auxiliary plate 85 has a first arm opening 87a and a second arm opening 87b. The first arm 42a is inserted into the first arm opening 87a. The second arm 42b is inserted into the second arm opening 87b. The auxiliary plate 85 moves vertically in conjunction with the first arm 42a or the second arm 42b. The auxiliary leaf spring 86 biases the auxiliary plate 85 to return it to its initial position. The auxiliary plate 85 and the auxiliary leaf spring 86 assist in locking and unlocking the first slide member 33 and the second slide member 34 in accordance with the key unlocking operation.

[0052] Here, the first slide member 33 moves (slides) in a first sliding direction in response to the rotation of the key inserted in the cylinder lock 11 (keyhole 11a) in a first rotation direction. The first direction is specifically the left rotation direction (counterclockwise direction). The first sliding direction is specifically the vertically upward direction. The second slide member 34 moves (slides) in a second sliding direction in response to the rotation of the key inserted in the cylinder lock 11 (keyhole 11a) in a second rotation direction. The second direction is specifically the right rotation direction (clockwise direction). The second sliding direction is specifically the vertically downward direction.

[0053] The rotation angle in the first rotation direction based on the initial position of the key inserted in the cylinder lock 11 (keyhole 11a) may be called the first rotation angle. The maximum value (absolute value) of the first rotation angle may be called the first maximum rotation angle. The boundary angle at which the lock switches from locked to unlocked in the first rotation direction may be called the first unlocking start angle. The key may be rotatable in the first rotation direction to an angle equal to or greater than the first unlocking start angle. In other words, the first maximum rotation angle may be equal to or greater than the first unlocking start angle. The first rotation angle at which unlocking is possible may be called the first unlocking angle. The first unlocking angle may be any first rotation angle at which unlocking is possible, and may be a first rotation angle within a range from the first unlocking start angle to the first maximum rotation angle.

[0054] The rotation angle in the second rotation direction based on the initial position of the key inserted in the cylinder lock 11 (keyhole 11a) may be called the second rotation angle. The maximum value (absolute value) of the second rotation angle may be called the second maximum rotation angle. The boundary angle at which the lock switches from locked to unlocked in the second rotation direction may be called the second unlocking start angle. The key may be rotatable in the second rotation direction to the second unlocking start angle or more. In other words, the second maximum rotation angle may not only be equal to the second unlocking start angle, but also be equal to or more than the second unlocking start angle. The second rotation angle at which unlocking is possible may be called the second unlocking angle. The second unlocking angle may be any second rotation angle at which unlocking is possible, and may be a second rotation angle within the range from the second unlocking start angle to the second maximum rotation angle.

[0055] Also, the unlocking start position in the first rotation direction of the key inserted in the cylinder lock 11 (keyhole 11a) may be called the first unlocking start position, the maximum position in the first rotation direction may be called the first maximum position, and the unlockable position in the first rotation direction may be called the first unlockable position. The first unlocking start position corresponds to the first unlocking start angle, the first maximum position corresponds to the first maximum rotation angle, and the first unlockable position corresponds to the first unlocking angle. Also, the unlocking start position in the second rotation direction of the key inserted in the cylinder lock 11 (keyhole 11a) may be called the second unlocking start position, the maximum position in the second rotation direction may be called the second maximum position, and the unlockable position in the second rotation direction may be called the second unlockable position. The second unlocking start position corresponds to the second unlocking start angle, the second maximum position corresponds to the second maximum rotation angle, and the second unlockable position corresponds to the second unlocking angle.

[0056] The unlockable movement amount (sliding amount) of the first slide member 33 according to the rotation of the key in the first rotation direction may be referred to as the first movement amount (first sliding amount). The first movement amount indicates the movement amount of the first slide member 33 when the key is rotated by the first unlocking angle from the initial position to the first unlockable position. The first movement amount may be the movement amount of the first slide member 33 when the key is rotated by the first unlocking start angle from the initial position to the first unlocking start position, or may be the movement amount of the first slide member 33 when the key is rotated by the first maximum rotation angle from the initial position to the first maximum position.

[0057] The unlockable movement amount (sliding amount) of the second slide member 34 according to the rotation of the key in the second rotation direction may be referred to as the second movement amount (second sliding amount). The second movement amount indicates the movement amount when the key is rotated from the initial position to the second unlockable position by the second unlocking angle. Note that the second movement amount may be the movement amount of the second slide member 34 when the key is rotated from the initial position to the second unlocking start position by the second unlocking start angle, or may be the movement amount of the second slide member 34 when the key is rotated from the initial position to the second maximum position by the second maximum rotation angle.

[0058] The torque (operation torque) that allows the key to be unlocked in the first rotation direction may be referred to as the first torque. The first torque refers to the torque when the key is rotated from the initial position to the first unlocking position, or when the key is rotated in the first direction until the movement amount of the first sliding member 33 becomes the first movement amount. The first torque may be the maximum value when the key is rotated from the initial position to the first unlocking start position, or may be the maximum value when the key is rotated from the initial position to the first maximum position.

[0059] The torque (operation torque) that allows the key to be unlocked in the second rotation direction may be referred to as the second torque. The second torque refers to the torque when the key is rotated from the initial position to the second unlocking position, or when the key is rotated in the second direction until the movement amount of the second slide member 34 becomes the second movement amount. The second torque may be the maximum value when the key is rotated from the initial position to the second unlocking start position, or may be the maximum value when the key is rotated from the initial position to the second maximum position.

[0060] FIG. 12 is a diagram illustrating the relationship between the rotation angle of the key, the amount of movement of the first sliding member 33 or the second sliding member 34, and the operating torque of the key.

[0061] As shown in Fig. 12, in the locking device 21, the first unlocking angle and the second unlocking angle are not substantially the same. The first unlocking angle and the second unlocking angle being substantially the same means that the absolute value of the difference between the first unlocking angle and the second unlocking angle is 1° or less. More specifically, the first unlocking angle (its absolute value) is smaller than the second unlocking angle (its absolute value). In other words, the first unlocking angle (its absolute value) is smaller than the second unlocking angle (its absolute value) by more than 1°.

[0062] Furthermore, in the locking device 21, the first movement amount and the second movement amount are not substantially the same. The first movement amount and the second movement amount being substantially the same means that the absolute value of the difference between the first movement amount and the second movement amount is 1 mm or less. More specifically, the first movement amount (absolute value) is smaller than the second movement amount (absolute value). In other words, the first movement amount (absolute value) is smaller than the second movement amount (absolute value) by more than 1 mm.

[0063] In addition, in the locking device 21, the first torque and the second torque are not substantially the same. The first torque and the second torque being substantially the same means that the absolute value of the difference between the first torque and the second torque is 0.1 N·m or less. In other words, the first torque (absolute value) is smaller than the second torque (absolute value) by more than 0.1 N·m.

[0064] The first torque and the second torque are compared under the same conditions for the first torque and the second torque. For example, if the first torque indicates the maximum torque value up to the first maximum position, the second torque also indicates the maximum torque value up to the second maximum position, and if the first torque indicates the maximum torque value up to the first unlocking start position, the second torque also indicates the maximum torque value up to the second unlocking start position. In addition, not only the first torque and the second torque, but also the comparison between the first movement amount and the second movement amount and the comparison between the first unlocking angle and the second unlocking angle are performed under the same conditions as in the comparison of torque.

[0065] Here, the configuration in which the first unlocking angle is smaller than the second unlocking angle may be, for example, by providing the hook portion 51, the hook portion 61, and each locking portion such that the distance from the initial position of the hook portion 51 of the first slide member 33 to the locking portion of the front door 9 is shorter than the distance from the initial position of the hook portion 61 of the second slide member 34 to the locking portion of the outer frame 3. Also, this may be achieved by making the rotation range within the cylinder lock 11 different between the first rotation direction and the second rotation direction.

[0066] The first movement amount is smaller than the second movement amount, for example, as follows. For example, the clearance between the first arm 42a and the upper end of the first arm opening 52a may be made larger than the clearance between the second arm 42b and the lower end of the second arm opening 52b. The larger the clearance of the first arm 42a, the later the timing at which the first sliding member 33 starts to move relative to the amount of key rotation, and as a result, the first movement amount is relatively reduced.

[0067] Also, for example, as described above, the first movement amount may be made smaller than the second movement amount by providing the hook portion 51, the hook portion 61 and each locking portion so that the distance from the initial position of the hook portion 51 of the first slide member 33 to the locking portion of the front door 9 is shorter than the distance from the initial position of the hook portion 61 of the second slide member 34 to the locking portion of the outer frame 3.

[0068] Also, for example, the clearance between the guide pillar 32b and the lower end of the guide hole 53 of the first slide member 33 may be made smaller than the clearance between the guide pillar 32b and the upper end of the guide hole 63 of the second slide member 34. When the clearance between the guide pillar 32b and the lower end of the guide hole 53 of the first slide member 33 is small, the vertical upward sliding of the first slide member 33 is restricted early, and as a result, the first movement amount is relatively reduced.

[0069] The first torque being smaller than the second torque can be achieved, for example, by making the clearance between the first arm 42a and the upper end of the first arm opening 52a larger than the clearance between the second arm 42b and the lower end of the second arm opening 52b. This is the same as the example of achieving the above-mentioned configuration in which the first movement amount is smaller than the second movement amount.

[0070] When the clearance of the first arm 42a is large, the timing at which the first slide member 33 starts moving is delayed as described above. Here, the first slide member 33 and the second slide member 34 are connected to each other by the biasing portion 65. When the timing at which the first slide member 33 starts moving is delayed, the timing at which the biasing portion 65 starts extending is also delayed. As a result, even if the first unlocking angle and the second unlocking angle are substantially the same, the extension amount of the biasing portion 65 when the first slide member 33 is moved is smaller than the extension amount of the biasing portion 65 when the second slide member 34 is moved. The biasing force of the biasing portion 65 increases as the extension amount increases. In other words, the biasing force when the first slide member 33 is moved is smaller than the biasing force when the second slide member 34 is moved. Therefore, the first torque corresponding to the first slide member 33 is relatively smaller than the second torque corresponding to the second slide member 34.

[0071] Here, it has been explained that the first unlocking angle and the second unlocking angle are approximately the same. However, as described above, when the first unlocking angle is smaller than the second unlocking angle, the first movement amount of the first slide member 33 is further reduced, and therefore the extension amount of the biasing portion 65 is further reduced. In other words, in this case, the first torque relative to the second torque can be further reduced.

[0072] In FIG. 12, an example is given in which the first unlocking angle is smaller than the second unlocking angle, the first movement amount is smaller than the second movement amount, and the first torque is smaller than the second torque. However, the configuration is not limited to satisfying all of these three types of conditions. For example, the locking device 21 may be configured such that the first movement amount is smaller than the second movement amount and the first torque is smaller than the second torque, regardless of the first unlocking angle and the second unlocking angle. Also, the locking device 21 may be configured such that the first unlocking angle is smaller than the second unlocking angle and the first movement amount is smaller than the second movement amount, regardless of the first torque and the second torque. Also, for example, the locking device 21 may be configured such that the first unlocking angle is smaller than the second unlocking angle and the first torque is smaller than the second torque, regardless of the first movement amount and the second movement amount.

[0073] In addition, the specific configuration for making the first unlocking angle smaller than the second unlocking angle, the specific configuration for making the first movement amount smaller than the second movement amount, and the specific configuration for making the first torque smaller than the second torque are not limited to the examples described above and can be designed arbitrarily.

[0074] As described above, in the locking device 21 of this embodiment, for example, the first movement amount is smaller than the second movement amount. Therefore, in the locking device 21 of this embodiment, a bodily difference can be imparted between the key operation feeling when wanting to unlock the front door and the key operation feeling when wanting to unlock the middle door. As a result, it is possible to impart an incentive to the key operator to prevent an operation error such as turning the key in the wrong direction.

[0075] Furthermore, in the locking device 21 of this embodiment, for example, the first torque is smaller than the second torque. Therefore, in the locking device 21 of this embodiment, it is possible to provide a further difference in bodily sensation between the key operation feeling when wanting to unlock the front door and the key operation feeling when wanting to unlock the middle door. As a result, it is possible to provide the key operator with a further motivation to prevent an operation error such as turning the key in the wrong direction.

[0076] Therefore, according to the locking device 21 of the present embodiment, key operation errors can be easily prevented.

[0077] Fig. 13 is a diagram for explaining modified examples of each condition of the locking device 21. As shown in Fig. 13, in this modified example, the first unlocking angle and the second unlocking angle are not substantially the same, and the first unlocking angle is larger than the second unlocking angle. Also, in this modified example, the first movement amount and the second movement amount are not substantially the same, and the first movement amount is larger than the second movement amount. Also, in this modified example, the first torque and the second torque are not substantially the same, and the first torque is larger than the second torque.

[0078] Here, the configuration in which the first unlocking angle is larger than the first unlocking angle may be, for example, provided with the hook portion 51, the hook portion 61, and each locking portion such that the distance from the initial position of the hook portion 51 of the first slide member 33 to the locking portion of the front door 9 is longer than the distance from the initial position of the hook portion 61 of the second slide member 34 to the locking portion of the outer frame 3. Also, this may be achieved by making the rotation range within the cylinder lock 11 different between the first rotation direction and the second rotation direction.

[0079] A configuration in which the first movement amount is greater than the second movement amount can be achieved, for example, as follows. For example, the clearance between the first arm 42a and the upper end of the first arm opening 52a may be made smaller than the clearance between the second arm 42b and the lower end of the second arm opening 52b. The smaller the clearance of the first arm 42a, the earlier the timing at which the first sliding member 33 starts to move relative to the amount of key rotation, and as a result, the first movement amount is relatively increased.

[0080] Also, for example, as described above, the first movement amount may be made greater than the second movement amount by providing the hook portion 51, the hook portion 61 and each locking portion so that the distance from the initial position of the hook portion 51 of the first slide member 33 to the locking portion of the front door 9 is longer than the distance from the initial position of the hook portion 61 of the second slide member 34 to the locking portion of the outer frame 3.

[0081] Also, for example, the clearance between the guide pillar 32b and the upper end of the guide hole 63 of the second slide member 34 may be made smaller than the clearance between the guide pillar 32b and the lower end of the guide hole 53 of the first slide member 33. If the clearance between the guide pillar 32b and the upper end of the guide hole 63 of the second slide member 34 is small, the vertical downward sliding of the second slide member 34 is restricted early, and the second movement amount is reduced, resulting in a relative increase in the first movement amount.

[0082] The first torque being greater than the second torque can be achieved, for example, by making the clearance between the first arm 42a and the upper end of the first arm opening 52a smaller than the clearance between the second arm 42b and the lower end of the second arm opening 52b. This is the same as an example of achieving the above-mentioned configuration in which the first movement amount is greater than the second movement amount.

[0083] When the clearance of the first arm 42a is small, the timing at which the first slide member 33 starts to move is advanced as described above. When the timing at which the first slide member 33 starts to move is advanced, the timing at which the urging portion 65 starts to extend is also advanced. As a result, the amount of extension of the urging portion 65 when the first slide member 33 is moved is greater than the amount of extension of the urging portion 65 when the second slide member 34 is moved. In other words, the urging force when the first slide member 33 is moved is greater than the urging force when the second slide member 34 is moved. Therefore, the first torque corresponding to the first slide member 33 is relatively greater than the second torque corresponding to the second slide member 34.

[0084] Also, for example, the first torque may be made larger than the second torque by making the mass of the first slide member 33 equal to or larger than the mass of the second slide member 34. If the mass of the first slide member 33 and the mass of the second slide member 34 are the same, the second slide member 34 is moved vertically downward, but the first slide member 33 is lifted vertically upward. Since the first slide member 33 is lifted against gravity, the first torque becomes larger than the second torque. Then, when the mass of the first slide member 33 becomes larger than the mass of the second slide member 34, gravity becomes even larger, and the first torque required to lift the first slide member 33 becomes even larger.

[0085] In FIG. 13, an example is given in which the first unlocking angle is larger than the second unlocking angle, the first movement amount is larger than the second movement amount, and the first torque is larger than the second torque. However, the configuration is not limited to satisfying all of these three types of conditions. For example, the locking device 21 may be configured such that the first movement amount is larger than the second movement amount and the first torque is larger than the second torque, regardless of the first unlocking angle and the second unlocking angle. Also, the locking device 21 may be configured such that the first unlocking angle is larger than the second unlocking angle and the first movement amount is larger than the second movement amount, regardless of the first torque and the second torque. Also, for example, the locking device 21 may be configured such that the first unlocking angle is larger than the second unlocking angle and the first torque is larger than the second torque, regardless of the first movement amount and the second movement amount.

[0086] In addition, the specific configuration for making the first unlocking angle larger than the second unlocking angle, the specific configuration for making the first movement amount larger than the second movement amount, and the specific configuration for making the first torque larger than the second torque are not limited to the examples described above and can be designed arbitrarily.

[0087] As described above, in the locking device 21 of the modified example, for example, the first movement amount is larger than the second movement amount, and the first torque is larger than the second torque. Therefore, as in the above embodiment, it is possible to provide a further bodily difference between the operation feel of the key when unlocking the front door and the operation feel of the key when unlocking the middle door. Therefore, according to this modified example, it is possible to easily suppress key operation errors.

[0088] Although the preferred embodiment of the present invention has been described above with reference to the accompanying drawings, it goes without saying that the present invention is not limited to such an embodiment. It is clear that a person skilled in the art can think of various modifications or alterations within the scope of the claims, and it is understood that these also naturally belong to the technical scope of the present invention.

[0089] For example, in the above embodiment and modified example, the biasing portion 65 is provided to connect the first slide member 33 and the second slide member 34. However, a biasing portion that generates a biasing force to return the first slide member 33 to the initial position and a biasing portion that generates a biasing force to return the second slide member 34 to the initial position may be provided separately. In this case, the first biasing portion for the first slide member 33 may have one end connected to the first slide member 33 and the other end connected to the base member 32. Also, the second biasing portion for the second slide member 34 may have one end connected to the second slide member 34 and the other end connected to the base member 32. Also, in this case, the biasing force (e.g., spring constant, etc.) of the first biasing portion may be smaller than the biasing force (e.g., spring constant, etc.) of the second biasing portion, so that the first movement amount is smaller than the second movement amount and the first torque is smaller than the second torque. In this case, the biasing force of the first biasing portion (e.g., spring constant, etc.) may be made greater than the biasing force of the second biasing portion (e.g., spring constant, etc.), thereby making the first movement amount greater than the second movement amount and the first torque greater than the second torque.

[0090] In the above embodiment and modified example, the first slide member 33 is involved in unlocking the front door 9, and the second slide member 34 is involved in unlocking the middle door 5. However, a single slide member may be configured to be involved in both unlocking the front door 9 and the middle door 5. In this configuration with a single slide member, the slide member moves in a first sliding direction (e.g., vertically upward) in response to rotation of the key inserted into the cylinder lock 11 in a first rotation direction, and moves in a second sliding direction (e.g., vertically downward) in response to rotation of the key in a second rotation direction. For example, the front door 9 is unlocked by the slide member moving in the first sliding direction, and the middle door 5 is unlocked by the slide member moving in the second sliding direction. In this configuration, the first movement amount is the amount of movement of the slide member that can be unlocked in response to rotation of the key in the first rotation direction, and the second movement amount is the amount of movement of the slide member that can be unlocked in response to rotation of the key in the second rotation direction. Moreover, one end of the biasing portion is connected to the slide member, and the other end is connected to the base member 32. For example, the biasing portion extends relative to its initial length when the slide member is moved in a first sliding direction, and shortens relative to its initial length when the slide member is moved in a second sliding direction. The biasing portion generates a biasing force that restores the slide member from the extended or shortened state to its initial length, that is, a biasing force that attempts to return the slide member to its initial position. Note that the extension and shortening may be reversed.

[0091] In the above-mentioned configuration with one slide member, the first movement amount may be smaller than the second movement amount, and the first torque may be smaller than the second torque. For example, an arm is formed on the cam 41 connected to the cylinder lock 11, and an arm opening through which the arm is inserted is formed on the slide member. The clearance between the arm and the upper end (edge ​​on the first sliding direction side) of the arm opening may be larger than the clearance between the arm and the lower end (edge ​​on the second sliding direction side) of the arm opening. This makes it possible to make the movement start timing in the first sliding direction later than the movement start timing in the second sliding direction, and to make the first movement amount smaller than the second movement amount. Furthermore, the extension amount of the biasing part in the first sliding direction becomes smaller than the contraction amount of the biasing part in the second sliding direction, and to make the first torque smaller than the second torque.

[0092] In the above-mentioned configuration with one sliding member, the first unlocking angle may be smaller than the second unlocking angle. Also, the configuration may satisfy any two or more of the following relationships: the first movement amount is smaller than the second movement amount, the first torque is smaller than the second torque, and the first unlocking angle is smaller than the second unlocking angle.

[0093] In addition, in the above-mentioned configuration having one slide member, the first movement amount may be made larger than the second movement amount, and the first torque may be made larger than the second torque. For example, the clearance between the arm and the upper end of the arm opening may be made smaller than the clearance between the arm and the lower end of the arm opening. This makes it possible for the movement start timing in the first sliding direction to be earlier than the movement start timing in the second sliding direction, and for the first movement amount to be larger than the second movement amount. Furthermore, the extension amount of the biasing part in the first sliding direction becomes larger than the contraction amount of the biasing part in the second sliding direction, and the first torque can be made larger than the second torque.

[0094] In the above-mentioned configuration with one sliding member, the first unlocking angle may be greater than the second unlocking angle. Also, the configuration may satisfy two or more of the following relationships: the first movement amount is greater than the second movement amount, the first torque is greater than the second torque, and the first unlocking angle is greater than the second unlocking angle.

[0095] Furthermore, the magnitude relationships (FIGS. 12 and 13) of the rotation angle, movement amount, and operating torque in the above embodiment and modified example are satisfied when the middle door 5 and front door 9 are closed relative to the outer frame 3 (for example, the state in FIG. 3). However, this magnitude relationship is not limited to the state in which the middle door 5 and front door 9 are closed relative to the outer frame 3, but may also be satisfied when either or both of the outer frame 3 and the middle door 5 and the middle door 5 and the front door 9 are open (for example, the state in FIG. 1).
