[0004] The rear door is attached to the box body and is configured to be able to open and close the rear opening. The front lock mechanism has a lock part and a first biasing member. The lock part is configured to be displaceable between a locked position that prevents the front door from opening and an unlocked position that allows the front door to open in a closed state where the front opening is closed by the front door. The first biasing member biases the lock part toward the unlocked position.

[0005] The rear lock mechanism locks and unlocks the rear door. The switching mechanism includes a slide member and a second biasing member. The slide member is provided inside the box body and configured to be slidable in the front-rear direction between a restricted position and an allowed position that is a position rearward of the restricted position. The second biasing member biases the slide member from the restricted position toward the allowed position.

[0006] The slide member has a main body, a tilting portion, and a third biasing member. The main body extends in the front-rear direction. The tilting portion is tiltably supported at a front end of the main body. The third biasing member biases the tilting portion toward a neutral position of the tilting portion. The slide member is configured to slide forward to the restricted position by the main body being pressed forward by the rear door being closed.

[0007] The switching mechanism is configured to allow displacement of the locking part when the slide member is in the restricted position by causing the tilting part to tilt as it is pressed by the locking part in the middle of displacing from the unlocked position to the locked position. The switching mechanism is also configured to restrict displacement of the locking part by not tilting the tilting part even when pressed by the locking part in the locked position, and to allow displacement of the locking part to the unlocked position by releasing the abutment state between the locking part and the tilting part as the slide member slides to the permitted position.

[0008] According to such a box opening and closing system, the front door can be unlocked in conjunction with the opening operation of the rear door to enter a cargo receiving standby state by a mechanical configuration. [Prior art documents] [Patent documents]

[0009] [Patent Document 1] Patent No. 7460996 Summary of the Invention [Problem to be solved by the invention]

[0010] In such a box opening and closing system, it is desirable to realize, through a mechanical configuration, the door lock being unlocked in conjunction with the opening action of the door that opens and closes the front opening, and the box being put into a state of waiting to receive cargo. [Means for solving the problem]

[0011] Various aspects of a box opening and closing system for solving the above problems will be described below. [Aspect 1] A box body having an opening that opens forward and a storage space that communicates with the opening; A frame door that is shaped like a frame along the edge of the opening and is rotatably attached to the box body and configured to open and close the opening; a front door located in front of the frame door and rotatably attached to the box body, configured to open and close a portion of the opening that is not covered by the frame door; a frame door lock mechanism for locking and unlocking the frame door to the box body; a front door lock mechanism including a locking portion configured to be displaceable between a locked position that prevents the front door from opening relative to the frame door and an unlocked position that allows the front door to open relative to the frame door in a closed state in which the opening is closed by the front door, and a first biasing member that biases the locking portion toward the unlocked position; a switching mechanism including a support portion fixed to an inner wall of the box body, a tilting portion tiltably supported by the support portion, and a second biasing member biasing the tilting portion toward a neutral position of the tilting portion; The switching mechanism is configured to allow the locking part to be displaced by pressing and tilting the tilting part by the locking part while being displaced from the unlocked position towards the locked position, while restricting the displacement of the locking part by not tilting the tilting part even when pressed by the locking part in the locked position, and to release the abutment between the locking part and the tilting part by sliding on the tilting part as the front door opens together with the frame door, thereby allowing the locking part to be displaced to the unlocked position. Box opening and closing system.

[0012] According to this configuration, when the frame door is locked by the frame door lock mechanism, the front door is closed, and the locking portion of the front door lock mechanism is in the unlocked position, the front door is allowed to open relative to the frame door and is in a package receiving standby state. At this time, the delivery person can store the parcel in the storage space by operating the front door to open the opening. After storing the parcel, the delivery person operates the front door to close the opening. Then, when the delivery person operates the front door lock mechanism to displace the locking portion to the locked position, the locking portion presses the tilting portion to tilt. Since the tilting portion is biased toward the neutral position by the second biasing member, when the locking portion overcomes the tilting portion, the tilting portion returns to the neutral position.

[0013] In this state, when the delivery person releases the operating force of the front door lock mechanism, the lock portion presses the tilting portion by being biased by the first biasing member. However, since the tilting portion does not tilt even when pressed by the lock portion in the locked position, the displacement of the lock portion to the unlocked position is restricted. This causes the lock portion to be held in the locked position. That is, the front door is locked to the frame door in the closed state. As described above, since the frame door is locked, the front door is locked in the closed state.

[0014] On the other hand, when the recipient operates the frame door lock mechanism to open the frame door to retrieve the parcel, the front door opens together with the frame door, causing the lock part to slide on the tilt part, releasing the abutment between the lock part and the tilt part. This allows the lock part to be displaced to the unlocked position, and the lock part returns to the unlocked position by the biasing force of the first biasing member. In other words, the front door is in a state of waiting to receive the parcel.

[0015] According to the above-described configuration, the front door can be unlocked in conjunction with the opening operation of the front door to enter a state of waiting for receiving cargo by a mechanical configuration. [Aspect 2] The front door lock mechanism is A shaft portion supported on the front door so as to be rotatable about an axis extending in the front-rear direction; an operation knob connected to a front end of the shaft portion, The lock portion is connected to the shaft portion and configured to engage with the frame door in the lock position and not to engage with the frame door in the unlock position, The first biasing member biases the locking portion to rotate toward the unlocked position. 2. A box opening and closing system according to embodiment 1.

[0016] According to this configuration, the front door lock mechanism can be realized with a simple configuration including the shaft portion, the operation knob, the lock portion, and the first biasing member. [Aspect 3] The frame door lock mechanism is a cylinder lock that locks and unlocks the frame door to the box body. The box opening and closing system according to embodiment 1 or embodiment 2.

[0017] With this configuration, the frame door lock mechanism can be easily locked and unlocked by a simple operation of inserting a mechanical key into the keyhole of the cylinder lock and turning it. Effect of the Invention

[0018] According to the present invention, the front door can be mechanically unlocked in conjunction with the opening operation of the front door to enter a state of waiting for receiving cargo. [Brief description of the drawings]

[0029] The reinforcing member 16 in this embodiment is formed by bending a metal pipe having a rectangular cross section. The reinforcing member 16 is fixed to the door body 15 by welding or the like. As shown in FIG. 6, when the frame door 14 is in a closed state, the vertical edges 15c, 16c are adjacent to the regulating plate 11A in the front-rear direction.

[0030] <Front door 18> As shown in Figures 1 to 7, the front door 18 is located in front of the frame door 14 and is rotatably attached to the box body 10, and is configured to open and close the portion of the opening 11 that is not covered by the frame door 14.

[0031] The front door 18 is a flat plate having a generally rectangular shape when viewed from the front. The front door 18 of this embodiment is rotatably attached via a hinge (not shown) provided on the other side (left side when viewed from the front) of the opening 11 in the width direction.

[0032] As shown in FIGS. 1, 2, and 4 to 6, the front door 18 is provided with a hole 18a for allowing a frame door lock mechanism 20, which will be described later, to escape. As shown in Figures 1 to 5, in this embodiment, the upper edge of the front door 18 is set below the lower edge of the drop-in opening 15A and above the lower edge of the upper edge portion 15a of the door body 15 so that the drop-in opening 15A of the frame door 14 is exposed to the outside.

[0033] As shown in FIGS. 1 to 3 and 5, a handle 19 that protrudes forward is attached to the outer surface of one widthwise side (the right side when viewed from the front) of the front door . The front door 18 of this embodiment is made of a metal plate.

[0034] <Frame door lock mechanism 20> As shown in FIGS. 1 to 4 and 6, the frame door lock mechanism 20 locks and unlocks the frame door 14 to the box body 10. As shown in FIGS.

[0035] The frame door lock mechanism 20 is a cylinder lock of known construction, and includes a cylinder 21, a plug 22, and a lock piece 24. As shown in FIG. 6, the cylinder 21 is attached to the widened portion 15C of the frame door 14.

[0036] The plug 22 is rotatably provided inside the cylinder 21. A keyhole 23 is provided on the front surface of the plug 22. 3, 4, and 6, the lock piece 24 is connected to the rear end of the plug 22. The lock piece 24 is configured to be rotatable between a locked position that prevents the frame door 14 from opening and an unlocked position that allows the frame door 14 to open when the frame door 14 is closed.

[0037] 4, the lock position of the lock piece 24 is the 9 o'clock position when viewed from behind. The lock piece 24 is configured to engage with an engagement edge 11a of the regulating plate 11A in the locked position.

[0038] 3, the unlocked position of the lock piece 24 is the 6 o'clock position. The lock piece 24 is configured not to engage with the engagement edge 11a in the unlocked position. <Front door lock mechanism 30> As shown in FIGS. 2 and 7, the front door lock mechanism 30 has a shaft portion 31, an operation knob 32, a lock portion 33, and a first biasing member .

[0039] As shown in FIG. 2, the front door lock mechanism 30 is provided in the front door 18 below the hole 18a. 2 and 7, the shaft portion 31 is supported by the front door 18 so as to be rotatable about an axis extending in the front-rear direction. The operation knob 32 is connected to the front end of the shaft portion 31 and is located outside the front door 18.

[0040] The lock portion 33 is connected to the rear end of the shaft portion 31 and extends radially outward from the shaft portion 31 . The locking portion 33 is configured to be displaceable between a locked position (see Figure 7) that prevents the front door 18 from opening relative to the frame door 14 when the opening 11 is closed by the front door 18, and an unlocked position (see Figure 2) that allows the front door 18 to open relative to the frame door 14.

[0041] 4, the locking position of the locking portion 33 is the 9 o'clock position when viewed from the rear. The locking portion 33 is configured to engage with the vertical edge portion 16c of the frame door 14 in the locked position.

[0042] As shown in FIG. 7, the regulating plate 11A is provided with a recess 11b for allowing the locking portion 33 in the locked position to escape. 2, the unlocked position of the locking portion 33 is the 12 o'clock position. The locking portion 33 is configured not to engage with the vertical edge portion 16c of the frame door 14 in the unlocked position.

[0043] 2 and 7, the first biasing member 34 rotationally biases the locking portion 33 toward the unlocked position. The first biasing member 34 in this embodiment is a torsion coil spring that is provided so as to cover the outer circumferential surface of the shaft portion 31 and has one end and the other end that are attached to the front door 18 and the locking portion 33, respectively.

[0044] <Switching mechanism 40> As shown in FIGS. 4 and 5, the switching mechanism 40 includes a support portion 41, a tilting portion 42, a second biasing member 43, and a bracket 44.

[0045] The support portion 41 has a cross section shaped like an inverted U that opens downward. The support portion 41 is fixed to the inner wall 13 of the box body 10 via a bracket 44. The tilting portion 42 is supported by the support portion 41 so as to be tiltable. The tilting portion 42 has a U-shaped cross section that opens downward. The rear end portion of the tilting portion 42 is accommodated inside the support portion 41.

[0046] The support portion 41, the tilting portion 42, and the bracket 44 are made of, for example, a metal plate. As shown in Fig. 5, the rear end of the tilting part 42 is connected to the support part 41 via a tilting shaft part 45 having an axis extending in the width direction. The tilting part 42 is supported by the support part 41 so as to be tiltable around the axis of the tilting shaft part 45. A cushioning material (not shown) is attached to the underside of the top wall of the support part 41 to absorb the impact of a collision with the upper surface of the top wall of the tilting part 42. The cushioning material is made of rubber, for example.

[0047] The second biasing member 43 biases the tilting portion 42 toward the neutral position of the tilting portion 42. In the neutral position, the tilting portion 42 abuts against the cushion material and assumes a posture along the front-rear direction.

[0048] The second biasing member 43 is a torsion coil spring that is arranged to cover the outer peripheral surface of the tilting shaft portion 45 and has one end and the other end supported by the lower surface of the top wall of the support portion 41 and the lower surface of the top wall of the tilting portion 42, respectively.

[0049] The switching mechanism 40 is configured to allow the rotational displacement of the locking part 33 by causing the tilting part 42 to tilt as it is pressed by the locking part 33 in the middle of its rotational displacement from the unlocked position to the locked position. The switching mechanism 40 is configured to restrict the rotational displacement of the locking part 33 by not tilting even when the tilting part 42 is pressed by the locking part 33 in the locked position. The switching mechanism 40 is also configured to allow the locking part 33 to be displaced to the unlocked position by releasing the abutment state between the locking part 33 and the tilting part 42 as the front door 18 opens together with the frame door 14 and sliding on the tilting part 42.

[0050] <Action of this embodiment> As shown in FIG. 8(a), when the frame door 14 is locked by the frame door lock mechanism 20, the front door 18 is closed, and the lock portion 33 of the front door lock mechanism 30 is in the unlocked position, the front door 18 is permitted to open relative to the frame door 14, and the device is in a package receiving standby state. At this time, the delivery person can store the parcel in the storage space 12 by operating the front door 18 to open the opening 11. After storing the parcel, the delivery person operates the front door 18 to close the opening 11. Then, the delivery person rotates the operation knob 32 of the front door lock mechanism 30 clockwise to displace the lock portion 33 to the locked position.

[0051] Then, as shown in Fig. 8(b), the locking portion 33 rotates and displaces, and presses the tilting portion 42 from above. This causes the tilting portion 42 to tilt about the tilting shaft portion 45 so that the front portion of the tilting portion 42 lowers, as shown in Fig. 8(c).

[0052] 8(d), the locking portion 33 climbs over the tilting portion 42 and is rotationally displaced to the locking position below the tilting portion 42. That is, the locking portion 33 is permitted to rotate toward the locking position. Since the tilting portion 42 is biased toward the neutral position by the second biasing member 43, when the locking portion 33 climbs over the tilting portion 42, the tilting portion 42 returns to the neutral position.

[0053] In this state, when the operating force of the front door lock mechanism 30 by the delivery person is released, the lock part 33 is biased by the first biasing member 34 to press the tilting part 42. However, even if the tilting part 42 is pressed by the lock part 33 in the locked position, it does not tilt upward from the neutral position where it abuts against the cushioning material, so that the displacement of the lock part 33 to the unlocked position is restricted. This holds the lock part 33 in the locked position. That is, the front door 18 is locked to the frame door 14 in the closed state. As described above, since the frame door 14 is locked, the front door 18 is locked in the closed state.

[0054] On the other hand, when the recipient inserts a mechanical key (not shown) into the keyhole 23 of the frame door lock mechanism 20 and turns the mechanical key to unlock the cylinder lock and open the frame door 14 in order to retrieve the parcel, the front door 18 opens together with the frame door 14, as shown in Fig. 9. As a result, the lock part 33 slides on the tilting part 42, and the abutment state between the lock part 33 and the tilting part 42 is released. This allows the lock part 33 to be displaced to the unlocked position, and the lock part 33 returns to the unlocked position by the biasing force of the first biasing member 34. In other words, the front door 18 enters a state of waiting to receive the parcel.

[0055] <Effects of this embodiment> (1-1) Because of the above-mentioned effects, the lock of the front door 18 can be unlocked in conjunction with the opening operation of the front door 18 to set the door in a state of waiting to receive cargo, by a mechanical configuration.

[0056] (1-2) The front door lock mechanism 30 can be realized with a simple configuration including the shaft portion 31, the operation knob 32, the lock portion 33, and the first biasing member . (1-3) The frame door lock mechanism 20 can be easily locked and unlocked by a simple operation of inserting a mechanical key into the keyhole 23 of the cylinder lock and turning it.

The operation knob 122 is connected to the front end of the shaft portion 121 and is located outside the first door 113.

[0063] The lock portion 123 is connected to the rear end of the shaft portion 121 and extends radially outward from the shaft portion 121 . The locking portion 123 is configured to be displaceable between a locked position that prevents the first door 113 from opening and an unlocked position that allows the first door 113 to open when the opening 111 is closed by the first door 113.

[0064] The locking portion 123 is configured to engage with a first engagement edge 115 of the opening 111 in the locked position shown in Fig. 10, but not to engage with the first engagement edge 115 in the unlocked position shown in Fig. 11. The engagement edge is the edge on the right side of the opening 111 when viewed from the front.

[0065] The first biasing member 124 rotationally biases the lock portion 123 toward the unlocked position. The first biasing member 124 in this embodiment is a torsion coil spring that is provided so as to cover the outer circumferential surface of the shaft portion 121 and has one end and the other end that are attached to the first door 113 and the lock portion 123, respectively.

[0066] <Second lock mechanism 130> The second lock mechanism 130 locks and unlocks the second door 114 to the box body 110, and includes a shaft portion 131, an operating knob 132, a lock piece 133, and a dial lock 134.

In more detail, the lock piece 133 is configured to engage with the second engagement edge 116 of the opening 111 in the locked position shown in Fig. 10, but not to engage with the second engagement edge 116 in the unlocked position shown in Fig. 11.

[0069] <Switching mechanism 140> The switching mechanism 140 includes a first slide member 150, a second slide member 160, a second biasing member 161, and a connecting member 170.

[0070] The first slide member 150 is provided inside the box body 110 and is configured to be slidable in the forward / backward direction between a first restricted position (see FIG. 10) and a first permissible position (see FIG. 11), which is a position rearward of the first restricted position.

[0071] The first slide member 150 has a main body portion 151 , a tilting portion 152 , and a third biasing member 153 . The main body 151 is supported so as to be slidable in the front-rear direction relative to the box body 110. In detail, the main body 151 is supported so as to be slidable in the front-rear direction via a bracket (not shown) fixed to the box body 110.

[0072] The main body 151 has a U-shaped cross section that opens downward. The tilting portion 152 is supported to be tiltable at the front end portion of the main body portion 151. The tilting portion 152 has a U-shaped cross section that opens downward. The rear end portion of the tilting portion 152 is accommodated inside the main body portion 151.

[0073] The rear end of the tilting part 152 is connected to the main body 151 via a tilting shaft 155 having an axis extending in the width direction. The tilting part 152 is supported by the main body 151 so as to be tiltable around the axis of the tilting shaft 155. A cushioning material (not shown) is attached to the underside of the top wall of the main body 151 to absorb the impact of a collision with the upper surface of the top wall of the tilting part 152.

[0074] The third biasing member 153 biases the tilting portion 152 toward the neutral position of the tilting portion 152. In the neutral position, the tilting portion 152 abuts against the cushion material and assumes a posture along the front-rear direction.

[0075] The third biasing member 153 is a torsion coil spring that is arranged to cover the outer peripheral surface of the tilting shaft portion 155 and has one end and the other end supported by the lower surface of the top wall of the main body portion 151 and the lower surface of the top wall of the tilting portion 152, respectively.

[0076] The second slide member 160 is provided inside the box body 110, and configured to be slidable in the front-rear direction between a second restricted position (see FIG. 10) and a second permitted position (see FIG. 11) which is a position forward of the second restricted position. In detail, the second slide member 160 is supported via a bracket (not shown) fixed to the box body 110 above the first slide member 150 so as to be slidable in the front-rear direction.

[0077] The second biasing member 161 biases the second slide member 160 from the second restricting position toward the second allowing position. The second biasing member 161 has the same configuration as the "second biasing member 42" in the "Description of the Invention" of Patent Document 1, but has a biasing direction that is reversed from that of the "second biasing member 42".

[0078] The connecting member 170 connects the first slide member 150 and the second slide member 160, and is configured to transmit the force that causes the second slide member 160 to slide forward or backward to the first slide member 150, thereby causing the first slide member 150 to slide backward or forward.

[0079] The connecting member 170 extends in the up-down direction. The connecting member 170 is supported rotatably with respect to the inner wall of the box body 110 by a rotation support part 173 provided at the center position of the connecting member 170 in the up-down direction.

[0080] The lower end of the connecting member 170 and the rear end of the first slide member 150 are rotatably connected via a rotation shaft portion 171 having an axis extending in the width direction. The upper end of the connecting member 170 and the rear end of the second slide member 160 are rotatably connected via a rotation shaft portion 172 having an axis extending in the width direction.

[0081] The first slide member 150 is configured to slide forward to the first restricting position as the second slide member 160 is pressed rearward by the second door 114 being closed.

[0082] The switching mechanism 140 is configured to permit rotational displacement of the locking part 123 when the first slide member 150 is in the first restricted position by pressing and tilting the tilting part 152 by the locking part 123 in the middle of rotating and displacing from the unlocked position to the locked position. The switching mechanism 140 is configured to restrict the rotational displacement of the locking part 123 by not tilting even when the tilting part 152 is pressed by the locking part 123 in the locked position. The switching mechanism 140 is also configured to permit the locking part 123 to rotate and displace to the unlocked position by releasing the abutment state between the locking part 123 and the tilting part 152 as the first slide member 150 slides to the first permitted position.

[0083] <Action of this embodiment> As shown in FIG. 10, when the second door 114 is locked by the second locking mechanism 130, the first door 113 is closed, and the locking portion 123 of the first locking mechanism 120 is in the unlocked position as shown by the two-dot chain line in the figure, the first door 113 is allowed to open and is in a package receiving standby state. At this time, the delivery person can store the parcel in the storage space 112 by operating the first door 113 to open the opening 111. After storing the parcel, the delivery person operates the first door 113 to close the opening 111. Then, the delivery person rotates the operating knob 122 of the first locking mechanism 120 clockwise to displace the locking portion 123 to the locked position.

[0084] Then, the tilting portion 152 is pressed and tilted by the locking portion 123. Since the tilting portion 152 is biased toward the neutral position by the third biasing member 153, when the locking portion 123 overcomes the tilting portion 152, as shown by the solid line in FIG. 10, the tilting portion 152 returns to the neutral position.

[0085] In this state, when the operating force of the first locking mechanism 120 by the delivery person is released, the locking part 123 is biased by the first biasing member 124 and presses the tilting part 152. However, since the tilting part 152 does not tilt even when pressed by the locking part 123 in the locked position, the displacement of the locking part 123 to the unlocked position is restricted. This holds the locking part 123 in the locked position. In other words, the first door 113 is locked in the closed state.

[0086] On the other hand, as shown in FIG. 11, when the recipient operates the dial lock 134 of the second lock mechanism 130 to open the second door 114 in order to take out the parcel, the pressing force acting on the second slide member 160 by the second door 114 is released. As a result, the second slide member 160 slides forward from the second restricting position to the second allowing position by the biasing force of the second biasing member 161. In addition, the first slide member 150 slides backward from the first restricting position to the first allowing position. As a result, the abutment state between the tilting portion 152 and the locking portion 123 is released, and the locking portion 123 returns to the unlocked position by the biasing force of the first biasing member 124. That is, the first door 113 is in a state of waiting for receiving goods.

[0087] <Effects of this embodiment> (2-1) By providing the above-mentioned functions, the lock of first door 113 can be unlocked in conjunction with the opening operation of second door 114 to set the door in a load-receiving standby state by a mechanical configuration.

[0088] (2-2) The first lock mechanism 120 can be realized by a simple configuration including the shaft portion 121, the operation knob 122, the lock portion 123, and the first biasing member . <Example of change> This embodiment can be modified as follows: This embodiment and the following modifications can be combined with each other to the extent that there is no technical contradiction.

[0089] In the first embodiment, the frame door 14 does not have to have the insertion opening 15A. In this case, the shelf board 10A can be omitted. In the first embodiment, the frame door lock mechanism 20 may be a digital key that is opened and closed by a motor. In this case, the digital key may be opened and closed using a smartphone or the like. The frame door lock mechanism 20 may be a mechanism that can be operated by both a mechanical key and a digital key.

[0090] In the first embodiment, the frame door lock mechanism 20 may be a combination lock that locks and unlocks the frame door 14 to the box body 10. <Additional Notes> The above embodiment includes the configurations described in the following supplementary notes.

[0091] [Appendix 1] A box body having an opening that opens forward and a storage space that communicates with the opening; A first door rotatably attached to the box body and configured to open and close the opening; A second door that is juxtaposed with the first door in a plane direction of the opening and is rotatably attached to the box body and configured to open and close the opening; a first lock mechanism including a lock portion configured to be displaceable between a locked position that prevents the first door from being opened and an unlocked position that allows the first door to be opened in a closed state in which the opening is closed by the first door, and a first biasing member that biases the lock portion toward the unlocked position; A second lock mechanism that locks and unlocks the second door to the box body; a first slide member provided inside the box body and configured to be slidable in the front-rear direction between a first restricting position and a first permissible position which is a position rearward of the first restricting position; a second slide member provided inside the box body and configured to be slidable in the front-rear direction between a second restricting position and a second permissible position which is a position forward of the second restricting position; a second biasing member which biases the second slide member from the second restricting position toward the second permissible position; and a connecting member which connects the first slide member and the second slide member and transmits a force with which the second slide member slides forward or backward to the first slide member to slide the first slide member backward or forward, the first slide member has a main body portion supported slidably in the front-rear direction with respect to the box body, a tilting portion tiltably supported at a front end portion of the main body portion, and a third biasing member biasing the tilting portion toward a neutral position of the tilting portion, and is configured to slide forward to the first restricting position as the second slide member is pressed rearward by the second door being closed, The switching mechanism is configured such that, when the first slide member is in the first restricted position, the tilting portion is pressed and tilted by the locking portion during displacement from the unlocked position toward the locked position, thereby allowing displacement of the locking portion, while restricting displacement of the locking portion by not tilting the tilting portion even when pressed by the locking portion in the locked position, and allowing displacement of the locking portion to the unlocked position by releasing the abutment state between the locking portion and the tilting portion as the first slide member slides to the first permitted position. Box opening and closing system.

[0092] According to this configuration, when the second door is locked by the second locking mechanism, the first door is closed, and the locking portion of the first locking mechanism is in the unlocked position, the first door is allowed to open and is in a package receiving standby state. At this time, the delivery person can store the parcel in the storage space by operating the first door to open the opening. After storing the parcel, the delivery person operates the first door to close the opening. Then, when the delivery person operates the first locking mechanism to displace the locking portion to the locked position, the tilting portion is pressed by the locking portion and tilts. Since the tilting portion is biased toward the neutral position by the third biasing member, when the locking portion overcomes the tilting portion, the tilting portion returns to the neutral position.

[0093] In this state, when the delivery person releases the operating force of the first locking mechanism, the locking portion is biased by the first biasing member to press the tilting portion. However, since the tilting portion does not tilt even when pressed by the locking portion in the locked position, the displacement of the locking portion to the unlocked position is restricted. This causes the locking portion to be held in the locked position. In other words, the first door is locked in the closed state.

[0094] On the other hand, when the recipient operates the second lock mechanism to open the second door to retrieve the parcel, the pressing force acting on the second slide member by the second door is released. As a result, the second slide member slides forward from the second restricting position to the second allowing position by the biasing force of the second biasing member. In addition, the first slide member slides backward from the first restricting position to the first allowing position. As a result, the abutment state between the tilting portion and the locking portion is released, and the locking portion returns to the unlocked position by the biasing force of the first biasing member. In other words, the first door is in a state of waiting to receive the parcel.

[0095] According to the above-described configuration, the first door can be unlocked in conjunction with the opening operation of the second door to enter a state of waiting for receiving luggage by a mechanical configuration. [Note] The first locking mechanism is A shaft portion supported on the first door so as to be rotatable about an axis extending in the front-rear direction; an operation knob connected to a front end of the shaft portion, The locking portion is connected to the shaft portion and configured to engage with an engagement edge of the opening in the locked position and not to engage with the engagement edge in the unlocked position, the first biasing member biases the lock portion to rotate toward the unlocked position, The switching mechanism is configured such that, when the first slide member is in the first restricted position, the tilting portion is pressed and tilted by the locking portion in the middle of rotational displacement from the unlocked position to the locked position, thereby allowing the rotational displacement of the locking portion, and that the tilting portion is not tilted even when pressed by the locking portion in the locked position, thereby restricting the rotational displacement of the locking portion. 2. A box opening and closing system as described in claim 1.

[0096] According to this configuration, the first lock mechanism can be realized with a simple configuration including the shaft portion, the operation knob, the lock portion, and the first biasing member. [Explanation of symbols]
