DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0008] A description will be given of a gate sleeve 10 in which a mailbox 11 and a delivery box 1 are provided according to one embodiment. Note that in this embodiment, the depth direction when a person faces the front of the delivery box 1 is referred to as the "depth direction." In the depth direction of the delivery box 1, the near side is referred to as the front side (diagonally left front side in FIG. 1), and the far side (diagonally right rear side in FIG. 1) is referred to as the rear side. Also, the left-right direction when a person faces the front of the mailbox 11 and delivery box 1 is referred to as the "left-right direction."
[0009] A mailbox 11 and delivery box 1 according to one embodiment are installed, for example, at a gate sleeve 10, as shown in Figures 1 and 2. The gate sleeve 10 is constructed by attaching the mailbox 11 and delivery box 1 to a wall having a predetermined thickness installed in front of an entrance, penetrating the wall in the thickness direction. The mailbox 11 is installed at the top of the gate sleeve 10, and the delivery box 1 is arranged next to the mailbox 11 below the mailbox 11.
[0010] The mailbox 11 of this embodiment is a mailbox that stores delivered items such as mail and newspapers. The mailbox 11 has, for example, a front-loading, rear-removal structure. The delivery box 1 is a parcel box that stores delivered parcels such as parcels. The delivery box 1 has, for example, a front-loading, rear-removal structure.
[0011] As shown in Figs. 1 to 3, the delivery box 1 includes a rectangular box-shaped delivery box body 2 (box body), a front inner door 3 (opening door, front opening door, inner opening door, front inner opening door) arranged on the inside of the front side and attached to the delivery box body 2 so as to be openable and closable, a front outer door 4 (outer opening door, front outer opening door) arranged on the outside of the front inner door 3 and attached to the delivery box body 2 so as to be openable and closable, a rear door 5 (rear opening door) arranged on the rear side and attached to the delivery box body 2 so as to be openable and closable, a front locking device 6 (locking mechanism), a rear locking device 7, and an interlocking unlocking mechanism 8. The delivery box 1 has the front inner door 3 arranged on the inside at the front side, and the front outer door 4 arranged on the outer rear side, and the front inner door 3 and the front outer door 4 form a double door.
[0012] As shown in Figures 3 to 5, the delivery box body 2 is formed in a cubic box shape and has a box body front opening 2a formed on the front side and opening forward, and a box body rear opening 2b formed on the rear side and opening backward. A delivery company puts a package in the delivery box 1 through the box body front opening 2a of the delivery box body 2, and takes the package out through the box body rear opening 2b of the delivery box body 2.
[0013] The front inner door 3 is attached to the inside of a double door constituted by the front inner door 3 and the front outer door 4, and is attached to the delivery box body 2 so as to be able to open and close the box body front opening 2a on the front side of the delivery box body 2. The front inner door 3 is formed in a rectangular shape of approximately the same size as the box body front opening 2a when viewed from the front side, and is disposed so as to close the box body front opening 2a when in the closed position.
[0014] A handle 3a is provided on the front surface of the front inner door 3. The handle 3a is provided on the front surface of the end portion on the door leading side of the front inner door 3, in the center in the up-down direction.
[0015] A rectangular inner door opening 31 (opening) extending laterally is formed at the top of the front inner door 3. The inner door opening 31 is formed by penetrating from the inside to the outside of the front inner door 3. The inner door opening 31 is formed smaller than the box body front opening 2a of the delivery box body 2, and constitutes an insertion port through which parcels of a predetermined size can be inserted.
[0016] The inner door opening 31 is formed smaller than the front opening 2a of the box body of the delivery box main body 2, so that even when the front inner door 3 is locked, parcels that can be placed inside the delivery box main body 2 through the inner door opening 31 can be placed inside the delivery box main body 2.
[0017] Here, the front locking device 6 of this embodiment is configured to restrict the movement of the front inner door 3 from the closed position to the open position and lock it when a certain operation (for example, an operation of moving the operation wall portion 665 upward as described later) is performed to move the front inner door 3 from the open position to the closed position. In such a case, in a delivery box in which the front inner door 3 is locked when the front inner door 3 is closed, conventionally, the front inner door 3 was not provided with an inner door opening 31, so that when a delivery person puts a package in the delivery box 1 and closes the front inner door 3, another package could not be put in the delivery box 1 unless the front inner door 3 was unlocked.
[0018] In contrast, in this embodiment, an inner door opening 31 is provided in the front inner door 3, so that even after the front inner door 3 is locked, parcels that can be placed inside the delivery box main body 2 through the inner door opening 31 in the front inner door 3 can be placed inside the delivery box main body 2.
[0019] A flap portion 32 capable of opening and closing the inner door opening 31 is attached to the front inner door 3. The flap portion 32 is configured to cover at least a portion of the inner door opening 31 and to be able to retreat from a state in which the inner door opening 31 is covered to a state in which the inner door opening 31 is not covered. The flap portion 32 may be configured to cover the entire inner door opening 31 or may be configured to cover a portion of the inner door opening 31. As shown in FIG. 6, the flap portion 32 has a plurality of flap plates 33 and a shaft member 34 provided at an upper portion and extending laterally.
[0020] Each of the multiple flaps 33 is formed in a vertically long rectangular plate shape. The multiple flaps 33 are arranged side by side in the horizontal direction inside the inner door opening 31 of the front inner door 3 of the delivery box 1. They are arranged so as to close the inner door opening 31 of the front inner door 3 on the inside of the delivery box 1.
[0021] The shaft member 34 is provided in a state in which it penetrates a pair of rising plates 36 arranged on the left and right opening edges of the inner door opening 31 of the front inner door 3. The pair of rising plates 36 are formed so as to rise from the inner surface of the front inner door 3. The rotation shaft support parts 332 of the multiple flap plates 33 are rotatably attached to the shaft member 34.
[0022] The multiple flap plates 33 are disposed inside the front inner door 3 facing the inner door opening 31 of the front inner door 3 so as to block at least a portion of the inner door opening 31 of the front inner door 3. The multiple flap plates 33 are configured to be rotatable about a rotation axis J1 of a shaft member 34 provided at the upper portion. The multiple flap plates 33 are configured to be able to rotate toward the inside of the delivery box 1 and retreat from the inner door opening 31 when pressed toward the inside of the delivery box main body 2 from the outside of the front inner door 3.
[0023] 6 to 8, the flap plate 33 has a flap plate main body 331 and a rotation shaft support portion 332 formed on an upper end portion of the flap plate main body 331. The flap plate main body 331 is formed in the shape of a plate having a width in the left-right direction and extending in the up-down direction.
[0024] The rotating shaft support portion 332 is attached to a shaft member 34 extending in the left-right direction and located on the upper opening edge of the inner door opening 31 on the inner surface of the front inner door 3, and is rotatable around the rotation axis J1 of the shaft member 34.
[0025] The rotating shaft support portion 332 has a pair of first arc-shaped portions 333 formed on both ends in the left-right direction, and a second arc-shaped portion 334 disposed between the pair of first arc-shaped portions 333.
[0026] The first arc-shaped portion 333 is formed with a center penetrating in the axial direction, and is formed in an arc-shaped shape from the end side of the thickness part of the upper end of the flap plate main body 331 on the front inner door 3 side to the opposite side to the front inner door 3, up to a range of approximately semicircular arc. The second arc-shaped portion 334 is formed with a center penetrating in the axial direction, and is formed in an arc-shaped shape from the end side of the thickness part of the upper end of the flap plate main body 331 on the opposite side to the front inner door 3 side to the front inner door 3 side, up to a range of approximately semicircular arc.
[0027] The first arc-shaped portion 333, the second arc-shaped portion 334, and the first arc-shaped portion 333 are arranged in this order from one side to the other in the left-right direction at the upper end of the flap plate 33. The shaft member 34 is arranged to penetrate through the center of the first arc-shaped portion 333 and the center of the second arc-shaped portion 334.
[0028] In the above-described flap section 32, the multiple flaps 33 are configured to be rotatable about a rotation axis J1 of a shaft member 34 provided at the upper portion, and to rotate and open toward the inside of the delivery box 1. As a result, even after the front inner door 3 is closed, parcels of a size that can be placed inside the delivery box 1 from the inner door opening 31 of the front inner door 3 can be placed through the inner door opening 31.
[0029] When putting a package through the inner door opening 31 of the front inner door 3, the flap plate 33 is pushed toward the inside of the delivery box 1, the flap plate 33 is rotated, and the package is put into the delivery box 1. The multiple flap plates 33 rotate temporarily when putting the package into the delivery box 1, and return to a predetermined position that blocks the inner door opening 31 after the package has been put in. This makes it possible to prevent the inside of the delivery box 1 from being seen through the inner door opening 31 when putting the package through the inner door opening 31. This makes it possible to improve the crime prevention performance. In addition, by providing the flap plate 33, it is possible to make it difficult to take out the package from the inside of the delivery box 1 even if someone puts their hand into the inside of the delivery box 1 through the inner door opening 31. This makes it possible to improve the crime prevention performance.
[0030] For further crime prevention reasons, the flap portion 32 can be configured to prevent hands from entering through the inner door opening 31 without retracting the multiple flap plates 33 from the inner door opening 31. In this case, as shown in FIG. 9, a rotation restriction rod 35 (restriction portion) for restricting the rotation of the flap plates 33 is disposed on the inner side of the front inner door 3 at a vertically intermediate position of the multiple flap plates 33. The rotation restriction rod 35 is provided penetrating a pair of rising plates 36 disposed on the left-right opening edges of the inner door opening 31 of the front inner door 3. By disposing the rotation restriction rod 35, the multiple flap plates 33 can be restricted from rotating.
[0031] As shown in Fig. 4 and Fig. 5, the front inner door 3 is provided with a front locking device 6. The front locking device 6 is provided in the center in the up-down direction on the end side of the door tip side of the front inner door 3. As shown in Fig. 10 and Fig. 11, the front locking device 6 has a base plate portion 61, a cylinder portion 62 (front cylinder portion), a hook-shaped sickle portion 63, a pair of latch portions 64 (front lock mechanism portions), a seesaw latch 65, a slide portion 66, and a cover member 67. Note that Fig. 10 illustrates a state in which the cover member 67 is attached to the front locking device 6, and Fig. 11 illustrates a state in which the cover member 67 is removed from the front locking device 6.
[0032] The base plate portion 61 is fixed to the inner surface of the end portion on the door tip side of the front inner door 3. The base plate portion 61 is formed in a plate shape that has a width in the left-right direction and extends in the up-down direction. On the inside side of the delivery box body 2 in the base plate portion 61, the inner end portion of the front inner door 3 of the cylinder portion 62, the hook-shaped sickle portion 63, the pair of latch portions 64, the seesaw latch 65, and the slide portion 66 are arranged.
[0033] With the hook-shaped sickle portion 63, the pair of latch portions 64, the seesaw latch 65, and the slide portion 66 attached to the inside of the delivery box body 2 in the base portion 61, a cover member 67 is attached to the outside thereof. As shown in Fig. 10, the cover member 67 is provided with a cover member opening 671 formed by opening a part of the cover member 67. From the cover member opening 671, an operation wall portion 665 of the slide portion 66 (described later) and a step surface portion 652 of a block portion 651 which is a part of the seesaw latch 65 (described later) are exposed to the outside.
[0034] As shown in Fig. 5 and Fig. 11, the cylinder part 62 is disposed on the upper side of the base plate part 61, penetrating the front inner door 3 in the thickness direction. The cylinder part 62 is provided on the front inner door 3, and can be operated from the outside of the front inner door 3. As shown in Fig. 5, a keyhole 622 is exposed on the outer surface side of the front inner door 3 of the cylinder part 62, and the cylinder part 62 can be rotated by inserting a key into the keyhole 622 and rotating it. As shown in Fig. 11, a hook-shaped sickle part 63 is fixed by a screw 63a to a rear end part 621 of the cylinder part 62 penetrating the front inner door 3 in the thickness direction.
[0035] 11 and 12, the hook-shaped sickle portion 63 extends downward from a rear end portion 621 of the cylinder portion 62 penetrating the front inner door 3 in the thickness direction, and is then bent toward the front end of the front inner door 3 to form an L-shape with the front end of the front inner door 3 open. The hook-shaped sickle portion 63 can be rotated by rotating the cylinder portion 62. The hook-shaped sickle portion 63 rotates about the rotation axis J2 by rotating the cylinder portion 62, and the latch piece 653 of the seesaw latch 65 (described later) rotates about the rotation axis J3, so that the latch piece 653 of the seesaw latch 65 can be engaged with and disengaged from the hook-shaped sickle portion 63.
[0036] As shown in Fig. 11, the slide portion 66 is attached to the surface of the base portion 61 opposite to the front inner door 3 so as to be slidable in the vertical direction. The slide portion 66 is biased downward by a biasing member 66a. The slide portion 66 has a vertically extending slide portion 661 extending in the vertical direction, an upper end latch regulating portion 662 formed at the upper end of the vertically extending slide portion 661, a lower end latch regulating portion 663 formed at the lower end of the vertically extending slide portion 661, a pair of seesaw latch mounting pieces 664, and an operation wall portion 665.
[0037] The vertically extending slide portion 661 is formed to extend in the vertical direction along the end side of the base plate portion 61 on the door base side of the front inner door 3. The upper end latch regulating portion 662 and the lower end latch regulating portion 663 protrude from the upper end and lower end of the vertically extending slide portion 661 toward the door end side of the front inner door 3.
[0038] When the latch piece 642 of the latch portion 64 (described later) is rotated, the slide portion 66 moves in the vertical direction, thereby allowing the latch piece 642 to rotate when it is not positioned between the rear end 642c of the latch piece 642 and the base portion 61, and restricting the rotation of the latch piece 642 so that the latch piece 642 does not rotate when it is positioned between the rear end 642c of the latch piece 642 and the base portion 61.
[0039] The pair of seesaw latch attachment pieces 664 are provided spaced apart in the left-right direction near the vertical center of the vertically extending slide portion 661. A seesaw latch 65 (described later) is attached to the pair of seesaw latch attachment pieces 664 so as to be rotatable about a rotation axis J3.
[0040] The operation wall 665 is formed in a rectangular parallelepiped shape protruding into the interior of the delivery box 1 at a position lower than the vertical center of the base plate 61. One left-right side of the operation wall 665 is connected to a portion lower than the vertical center of the vertically extending slide portion 661. The operation wall 665 is an operation wall for sliding the slide portion 66 upward with the front inner door 3 in the open position when the front inner door 3 is locked by moving the front inner door 3 from the open position to the closed position with the front inner door 3 in the open position.
[0041] 11, the seesaw latch 65 is disposed below the hook-shaped sickle portion 63 attached to the inner end of the front inner door 3 of the cylinder portion 62. The seesaw latch 65 has a block portion 651 and a latch piece 653 connected to an upper portion of the block portion 651. A stepped surface portion 652 is formed on the surface of the block portion 651 facing the inside of the delivery box 1.
[0042] The step surface portion 652 has an upper-side lower inclined surface 652a arranged on the upper side, a lower-side upper inclined surface 652b arranged on the lower side, and a step surface 652c connecting the upper-side lower inclined surface 652a and the lower-side upper inclined surface 652b.
[0043] The seesaw latch 65 is configured to be rotatable around the rotation axis J3, and is attached to a pair of seesaw latch mounting pieces 664 of the slide portion 66 with the latch piece 653 pressed against the side that engages with the hook-shaped sickle portion 63 and biased.
[0044] When the stepped surface portion 652 is pressed downward, the seesaw latch 65 rotates about the rotation axis J3. As a result, the latch piece 653 and the hook-shaped sickle portion 63 are disengaged from each other from the engaged state. When the latch piece 653 and the hook-shaped sickle portion 63 are disengaged from each other, the slide portion 66, which is biased downward, moves downward.
[0045] The pair of latch portions 64 are provided separately on the upper end side and the lower end side of the base plate portion in the portion of the base plate portion on the door tip side of the front inner door 3. Each of the pair of latch portions 64 has a support case 641, a latch piece 642, and a biasing member 643. The latch piece 642 is supported rotatably about a rotation axis J4.
[0046] The latch piece 642 has a horizontal extending portion 642a extending from the inside to the outside in the left-right direction along the inner surface of the front inner door 3, and an engaging claw portion 642b connected to the outer left-right tip of the horizontal extending portion 642a. The engaging claw portion 642b is configured to be able to protrude toward the receiving metal fitting 21 provided on the inner side of the opening edge of the box body front opening 2a of the delivery box body 2.
[0047] The biasing member 643 biases the latch piece 642 in a direction pressing it against the receiving metal fitting 21 provided on the inner side of the opening edge of the box body front opening 2a of the delivery box body 2.
[0048] As shown in FIG. 12, when the rear end 642c of the latch piece 642 is not restricted by the upper end latch restriction portion 662 and the lower end latch restriction portion 663 of the slide portion 66, the latch portion 64 is capable of moving the front inner door 3 from the open position to the closed position, and is also capable of moving the front inner door 3 from the closed position to the open position.
[0049] 11, when the front inner door 3 is in the open position, if a certain operation (operation to move the operation wall portion 665 upward) is performed and the rear end portion 642c of the latch piece 642 is restricted by the upper end latch restricting portion 662 and the lower end latch restricting portion 663, the latch portion 64 restricts the movement of the front inner door 3 from the closed position to the open position, thereby locking the front inner door 3. In this state, the front inner door 3 cannot be moved from the closed position to the open position.
[0050] The state in which the rear end 642c of the latch piece 642 is restricted by the upper end latch restricting portion 662 and the lower end latch restricting portion 663 when the front inner door 3 is in the open position can be created, for example, by the delivery person opening the unlocked front inner door 3 and placing a package inside, and then the delivery person moving the operating wall portion 665 upward, causing the slide portion 66 to move upward, and the upper end latch restricting portion 662 and the lower end latch restricting portion 663 restricting the movement of the rear end 642c of the latch piece 642.
[0051] Furthermore, when the front inner door 3 is in the closed position and in a locked state, the latch portion 64 can unlock the front inner door 3 by operating the cylinder portion 62, and the front inner door 3 can be unlocked by operating it from the inside of the front inner door 3.
[0052] In detail, when unlocking the front inner door 3, a key is inserted into the keyhole 622 of the cylinder portion 62 from the outside of the front inner door 3 and rotated to disengage the hook-shaped sickle portion 63 from the latch piece 653 of the seesaw latch 65, and the slide portion 66 can be moved downward, thereby unlocking the front inner door 3. Also, by performing an operation of pushing down the seesaw latch 65 from the inside of the front inner door 3, the engagement between the latch piece 653 of the seesaw latch 65 and the hook-shaped sickle portion 63 can be disengaged, and the slide portion 66 can be moved downward, thereby unlocking the front inner door 3.
[0053] The operation of pushing down the seesaw latch 65 to disengage the latch piece 653 of the seesaw latch 65 from the hook-shaped sickle portion 63 can be performed, for example, by a child who is locked inside the delivery box 1 pushing down the seesaw latch 65, or, as described later, can be performed by pushing down the seesaw latch 65 using the unlocking operation portion 83 provided on the end side of the front locking device 6 side of the interlocking rod-shaped member 81 of the interlocking unlocking mechanism 8 (described later).
[0054] In the above front locking device 6, when the front inner door 3 is moved from the open position to the closed position by performing a certain operation (operation of moving the operation wall portion 665 upward), the latch portion 64 restricts the movement of the front inner door 3 from the closed position to the open position, thereby locking the front inner door 3. Also, when the front inner door 3 is located at the closed position and in a locked state, an operation of inserting a key into the keyhole 622 of the cylinder portion 62 and rotating it or an operation of pushing down the seesaw latch 65 is performed, whereby the engagement between the latch piece 653 of the seesaw latch 65 and the hook-shaped sickle portion 63 is released, and the slide portion 66, which is biased to move downward, is moved downward.
[0055] As a result, the upper end latch regulation portion 662 and the lower end latch regulation portion 663 of the slide portion 66 are retracted downward from the state in which they are located at the rear end portion 642c of the latch piece 642. Therefore, the rear end portion 642c of the latch piece 642 is no longer regulated by the upper end latch regulation portion 662 and the lower end latch regulation portion 663 of the slide portion 66, the front inner door 3 can be unlocked, and the front inner door 3 can be moved from the closed position to the open position.
[0056] 5, on the outer surface of the front inner door 3, below the keyhole 622 of the cylinder portion 62, a display unit 68 for displaying the locked or unlocked state of the front inner door 3 is disposed. The display unit 68 changes its display in conjunction with the movement of the slide portion 66, and turns, for example, red when the front inner door 3 is in a locked state, and turns, for example, green when the front inner door 3 is in an unlocked state, thereby displaying the locked or unlocked state of the front inner door 3.
[0057] As shown in Figures 3 to 5, the front outer door 4 is provided on the outside of the front inner door 3 so as to be openable and closable. The front outer door 4 is attached to the outside of the double door formed by the front inner door 3 and the front outer door 4, and is attached to the delivery box body 2 so as to be able to open and close the box body front opening 2a on the front side of the delivery box body 2. No locking device is provided on the front outer door 4. As shown in Figure 5, the front outer door 4 can be opened and closed when the front inner door 3 is closed.
[0058] 2 and 3, the rear door 5 is attached to the delivery box body 2 so as to be able to open and close the box body rear opening 2b on the rear side of the delivery box body 2. The rear door 5 is formed in a rectangular shape approximately the same as the box body rear opening 2b when viewed from the rear side, and is disposed so as to close the box body rear opening 2b when in the closed position.
[0059] As shown in Figures 3 and 4, the rear door 5 is provided with a rear locking device 7. The rear locking device 7 is provided in the center in the up-down direction on the end side of the door leading side of the rear door 5. As shown in Figures 5 and 13, the rear locking device 7 has a cylinder portion 71 (rear cylinder portion) and a rotating cam portion 72 (rear locking mechanism portion).
[0060] The cylinder portion 71 is disposed at the vertical center of the end portion on the door front side of the rear door 5, penetrating the rear door 5 in the thickness direction. The cylinder portion 71 is provided on the rear door 5 and can be operated from the outside of the rear door 5. A keyhole 711 (see FIG. 3) is exposed on the outer surface side of the rear door 5 of the cylinder portion 71, and the cylinder portion 71 can be rotated by inserting a key into the keyhole 711 and rotating it. A rotating cam portion 72 is fixed to an end portion 712 on the inside of the rear door 5 of the cylinder portion 71 by a screw 72a, as shown in FIG.
[0061] When the rear door 5 is in the closed position and in a locked state, the rotating cam portion 72 can unlock the rear door 5 by operating the cylinder portion 71. The rotating cam portion 72 is formed in a plate shape extending laterally from an end portion 712 of the cylinder portion 71 on the inside of the rear door 5. The rotating cam portion 72 can be rotated by rotating the cylinder portion 71.
[0062] The rotating cam portion 72 rotates about the rotation axis J5 by rotating the cylinder portion 71, whereby it can be engaged with and disengaged from the receiving plate 22 provided on the inner side of the opening edge of the box body rear opening 2b of the delivery box body 2. The rear door 5 is in a locked state when the rotating cam portion 72 engages with the receiving plate 22 provided on the inner side of the opening edge of the box body rear opening 2b of the delivery box body 2. The rear door 5 is in an unlocked state when the rotating cam portion 72 does not engage with the receiving plate 22 provided on the inner side of the opening edge of the box body rear opening 2b of the delivery box body 2.
[0063] 3, when the front inner door 3 and the rear door 5 are in the closed position, the interlocking unlocking mechanism 8 is disposed over a long range in the depth direction at the vertical center of the inner surface of the side panel 2c of the delivery box body 2 that is disposed on the side where the door edges of the front inner door 3 and the rear door 5 are located. When the front inner door 3 and the rear door 5 are locked and the rear door 5 is unlocked by operating the cylinder portion 71 of the rear locking device 7, the interlocking unlocking mechanism 8 unlocks the front inner door 3 in conjunction with the operation of the cylinder portion 71 of the rear locking device 7 to unlock the rear door 5.
[0064] As shown in Figure 13, the interlocking unlocking mechanism 8 has an interlocking rod-shaped member 81 extending from the rear locking device 7 side to the front locking device 6 side, a cam receiving portion 82 provided on the end side of the interlocking rod-shaped member 81 on the cylinder portion 71 side, an unlocking operation portion 83 provided on the end side of the interlocking rod-shaped member 81 on the front locking device 6 side, a biasing member 84 that biases the cam receiving portion 82 toward the rotating cam portion 72 side, and a case body 85.
[0065] The interlocking rod member 81 is disposed at the center in the vertical direction on the inner surface of the side panel 2c of the delivery box main body 2, and extends in the depth direction of the delivery box 1. The interlocking rod member 81 is supported rotatably about a rotation axis J6, which is a central axis extending in the extension direction of the interlocking rod member 81.
[0066] The cam receiver 82 is fixed to the end of the interlocking rod member 81 on the rear door 5 side in the longitudinal direction. The cam receiver 82 is formed to protrude in a direction perpendicular to the axial direction of the interlocking rod member 81. Since the cam receiver 82 is fixed to the end of the interlocking rod member 81 on the rear door 5 side in the longitudinal direction, it is rotatable about the rotation axis J6, similar to the interlocking rod member 81. The cam receiver 82 is urged by a urging member 84 toward the rotating cam portion 72 of the rear lock device 7.
[0067] The unlocking operation part 83 is fixed to the end of the interlocking rod member 81 on the front inner door 3 side in the longitudinal direction. The unlocking operation part 83 is formed to protrude in a direction perpendicular to the axial direction of the interlocking rod member 81. Since the unlocking operation part 83 is fixed to the end of the interlocking rod member 81 on the front inner door 3 side in the longitudinal direction, it is rotatable about the rotation axis J6, similar to the interlocking rod member 81.
[0068] Next, an operation of unlocking the front inner door 3 by the interlocking unlocking mechanism 8 in conjunction with the operation of the cylinder portion 71 of the rear locking device 7 to unlock the rear door 5 will be described when the rear door 5 is unlocked. When the rear door 5 is unlocked by operating the cylinder portion 71 of the rear locking device 7, the rotating cam portion 72 rotates to the side retracting from the cam receiving portion 82. As a result, the cam receiving portion 82 rotates in the clockwise direction C shown in FIG. 13 and FIG. 14 because it is biased in the clockwise direction C shown in FIG. 13 by the biasing member 84. As a result, in conjunction with the rotation of the cam receiving portion 82, the interlocking rod member 81 and the unlocking operation portion 83 also rotate in the clockwise direction C shown in FIG. 13 and FIG. 14 around the rotation axis J6.
[0069] Then, as the unlocking operation part 83 rotates in the clockwise direction C, the unlocking operation part 83 pushes the step surface 652c of the block part 651 of the seesaw latch 65 downward as shown in Fig. 12. This causes the block part 651 of the seesaw latch 65 to rotate downward about the rotation axis J3, and the latch piece 653 of the seesaw latch 65 and the hook-shaped sickle part 63 are disengaged, causing the slide part 66, which is biased downward, to move downward.
[0070] As a result, the upper end latch regulating portion 662 and the lower end latch regulating portion 663 of the slide portion 66 are retracted downward from the state where they are located at the rear end portion 642c of the latch piece 642. Then, the rear end portion 642c of the latch piece 642 is not regulated by the upper end latch regulating portion 662 and the lower end latch regulating portion 663 of the slide portion 66. Therefore, the front inner door 3 can be unlocked and moved from the closed position to the open position. In this way, the interlocking unlocking mechanism 8 rotates (moves) the interlocking rod-shaped member 81 in conjunction with the operation of the cylinder portion 71, thereby rotating (moving) the unlocking operation portion 83 to unlock the front inner door 3.
[0071] The delivery box 1 of this embodiment described above provides the following effects. The delivery box 1 of this embodiment includes a delivery box body 2, a front inner door 3, a cylinder portion 62 provided on the front inner door 3, and a latch portion 64 that locks the front inner door 3 when the front inner door 3 moves from the open position to the closed position by performing a certain operation (operation of moving the operation wall portion 665 upward), and can unlock the front inner door 3 by operating the cylinder portion 62 and can unlock the front inner door 3 by operation from the inside of the front inner door 3. The locking mechanism includes a front locking device 6, a rear door 5, a cylinder portion 71 provided on the rear door 5, and a rear locking device 7 having a rotating cam portion 72 capable of unlocking the rear door 5 by operating the cylinder portion 71; and when the front inner door 3 and the rear door 5 are in a locked state, and when the rear door 5 is unlocked by operating the cylinder portion 71 of the rear locking device 7, a linked unlocking mechanism 8 unlocks the front inner door 3 in conjunction with the operation of the cylinder portion 71 to unlock the rear door 5.
[0072] As a result, in the delivery box 1 where parcels can be put in from the front and taken out from the rear, when the front inner door 3 and the rear door 5 are locked, the front inner door 3 can be unlocked in conjunction with the unlocking of the rear door 5 by operating the cylinder portion 71 of the rear locking device 7. Therefore, the front inner door 3 can be easily unlocked by simply unlocking the rear door 5.
[0073] In this embodiment, the interlocking unlocking mechanism 8 has an interlocking rod-shaped member 81 extending from the rear locking device 7 side to the front locking device 6 side, and an unlocking operation part 83 provided on the end side of the interlocking rod-shaped member 81 on the front locking device 6 side, and moves the interlocking rod-shaped member 81 in conjunction with the operation of the cylinder part 71 of the rear locking device 7 to move the unlocking operation part 83 and unlock the front inner door 3. This makes it possible to unlock the front inner door 3 in conjunction with the unlocking of the rear door 5 with a simple configuration.
[0074] In this embodiment, the door of the delivery box 1 is configured as a double door consisting of a front inner door 3 and a front outer door 4. As a result, the cylinder portion 62 of the front locking device 6 provided on the front inner door 3 cannot be seen unless the front outer door 4 is opened, which prevents the cylinder portion 62 of the front locking device 6 from being illegally unlocked, thereby improving crime prevention performance. In addition, since the front outer door 4 covers the display portion 68, it is not possible to know whether or not a package is currently in the box unless the front outer door 4 is opened, which improves crime prevention performance.
[0075] A preferred embodiment of the delivery box 1 of the present disclosure has been described above, but the present disclosure is not limited to the above-described embodiment and can be modified as appropriate. [Explanation of symbols]
