Description

[Technical Field]

[0001] The present invention relates to a delivery box that is installed by penetrating the exterior wall of a housing complex such as an apartment building. [Background technology]

[0002] In recent years, various delivery lockers have been provided that enable delivery of parcels without the need for a courier and a recipient to meet face-to-face. A typical delivery locker has a lockable door on the front, and when the recipient is not at home, the courier opens the door, places the parcel inside the box, and then operates a locking / unlocking device to lock the door. By installing this delivery locker at the entrance to a building, the recipient can unlock the door and retrieve the parcel from the front. With such a typical delivery locker, the recipient must go outside to unlock the door and retrieve the parcel, which is cumbersome.

[0003] As a delivery box that can address this problem, for example, Patent Document 1 describes a delivery box that is installed so as to penetrate the exterior wall of a detached house, and has a package insertion opening that opens to the outside and a package removal opening that opens to the inside, with the package insertion opening having an outer door that can be locked with a locking device such as a combination lock, and the package removal opening having an inner door that can be opened and closed with a latch mechanism. With this type of delivery box that penetrates the exterior wall, the recipient can retrieve the package from either the outside or inside of the building. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2019-154516 A (Figs. 1 and 2) Summary of the Invention [Problem to be solved by the invention]

[0005] However, when multiple exterior-wall-through delivery boxes such as those described in Patent Document 1 are installed on the exterior wall of, for example, an entrance to an apartment building or other multi-family housing complex, and an empty delivery box is selected to store a parcel addressed to a specific resident, the following problem arises: A delivery company stores a parcel addressed to a specific resident in the delivery box, then operates the combination lock to lock the exterior door and places a non-delivery notice with the combination lock's PIN number in the recipient's mailbox, or sends the PIN number to the recipient's mobile device, so that only the recipient who has returned home from outside can open the exterior door using the PIN number and remove the parcel from the parcel insertion slot. However, because the interior door is closed only by a latch mechanism, there is a risk that a third party other than the recipient could forcibly pry open the interior door and steal the parcel.

[0006] To prevent this, it is possible to provide a locking / unlocking device such as a combination lock on the inner door. However, if a malfunction occurs in the combination lock or if the preset PIN number is forgotten, the inner door cannot be opened, and the problem arises that the delivery person must go outside the entrance, open the outer door using the PIN number specified by the delivery company, and remove the delivery item from the outer baggage insertion slot.

[0007] The present invention has been made in consideration of the above-mentioned problems, and aims to provide a delivery box that allows parcels to be picked up from either the outside or inside of a building. [Means for solving the problem]

[0008] In order to solve the above problems, the delivery box of the present invention comprises: In a delivery box comprising a box body installed to penetrate the exterior wall of a building, and a locking / unlocking mechanism for locking and unlocking an outer door and an inner door that respectively open and close the outdoor opening and indoor opening formed in the box body, the locking / unlocking mechanism is provided on the outdoor side and indoor side of the box body, respectively, and is characterized by comprising a pair of inner and outer operating units having movable members for placing the outer door and the inner door in a closed state or an openable state, a movable switching member that can be switched between an open-door restricted state that restricts the door-opening operation of the operating unit and an open-door restricted release state that releases the restriction, a pair of inner and outer selective locks for switching the movable switching member to the open-door restricted state or the open-door restricted release state, and an interlocking means for interlocking the selective locks with each other. According to this feature, the pair of inner and outer selective locks that switch the movable switching member between the door-opening restricted state and the door-opening restricted release state are linked by a linking means, so that when one selective lock is unlocked based on a PIN number or the like from the delivery company, the other selective lock is simultaneously unlocked, and both the outer and inner doors become openable. Therefore, by operating the inner and outer operating parts to open the doors respectively, the parcel can be taken out from either the outdoor opening or the indoor opening.

[0009] The movable members of the inner and outer operating parts are connected to each other by a connecting member extending in the inner and outer directions. According to this feature, when one of the operating parts is rotated to rotate one of the movable members and place one of the outer door and the inner door in a closed state or an openable state, the other movable member can be rotated in conjunction with the connecting member, and the other of the outer door and the inner door can be placed in a closed state or an openable state. Therefore, when retrieving a parcel from the outdoor opening or the indoor opening, it is not necessary to operate the indoor and outdoor operating parts separately.

[0010] The movable switching member is disposed between one of the inner and outer selection locks and the movable member so as to be engaged with and disengaged from the connecting member. According to this feature, by engaging and disengaging the movable switching member provided on either the inside or outside with the connecting member that connects the inside and outside movable members, it is possible to simultaneously switch between the door-opening restricted state and the door-opening restricted released state, so that only one movable switching member is required, thereby reducing costs.

[0011] The pair of inner and outer selective locks are dial locks, and the interlocking means comprises a driving gear provided on the pair of dial locks, an interlocking rod extending inward and outward directions, and driven gears attached to both ends of the interlocking rod and meshing with the inner and outer driving gears. According to this feature, the rotation of one dial lock is reliably transmitted to the other dial lock, so that the pair of inner and outer dial locks can be reliably interlocked.

[0012] The operating portion, the movable switching member, the selective lock and the interlocking means are assembled in a case separate from the box body and constitute a locking / unlocking unit. According to this feature, the locking / unlocking unit, which is configured by assembling each component in advance to the case, can be simply attached to the box body, thereby reducing the assembly man-hours and making it easy to manufacture the delivery box.

DETAILED DESCRIPTION OF THE INVENTION

[0014] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the accompanying drawings. [Example]

[0015] An embodiment of a delivery locker 1 according to the present invention will be described with reference to Figures 1 to 8. In the following description, the outdoor side will be referred to as the front and the indoor side as the rear. As shown in Figure 1, delivery lockers 1 are installed in multiple locations, such as at the entrance of an apartment building or other collective housing complex, penetrating an exterior wall W. After a delivery company places a parcel addressed to a specific resident in an available delivery locker, the recipient can retrieve the parcel from either the outside or inside of the exterior wall.

[0016] As shown in Figures 1 and 2, delivery box 1 is composed of box body 2 and locking / unlocking unit 3 attached to the left side of box body 2, with vertical and front-to-back dimensions approximately equal to those of box body 2. Box body 2 is formed into a box shape from metal, hard synthetic resin, or the like, and has an outdoor opening 4 that opens to the outdoors and an indoor opening 5 that opens to the indoors. Attached to outdoor opening 4 and indoor opening 5 are outer and inner doors 6 and 7 made of metal, synthetic resin, or the like, which can be opened and closed around hinges (not shown) on the right ends, respectively, so that they can be locked and unlocked by locking / unlocking mechanism 10, which will be described later.

[0017] The locking / unlocking unit 3 comprises a case body 8 with an open side facing the box body 2, a side cover 9 detachably attached to the case body 8 so as to close the open side, and a locking / unlocking mechanism 10 assembled in the internal space of the case body 8. The case body 8 and the side cover 9 constitute the case of the present invention.

[0018] As shown in Figures 3 and 4, the locking / unlocking mechanism 10 is attached to the front panel 8a and the lower part of the rear panel 8b of the case body 8 so as to be rotatable from the front and rear, and is equipped with a pair of inner and outer operating units 11, 11' that rotate inner and outer movable members 17, 17' (described later) to place the outer door 6 and the inner door 7 in a closed state or an openable state, a pair of inner and outer number-selectable dial locks 12, 12' as selective locks, an interlocking means 13 that interlocks the dial locks 12, 12', and a movable switching member 14 that is disposed between the outdoor movable member 17 and the dial lock 12 and switches the rotation of each operating unit 11, in particular the door-opening operation, between a door-opening restricted state that restricts the door-opening operation and a door-opening restricted release state that releases the restriction.

[0019] The inner and outer dial locks 12, 12' each have four horizontally rotatable dials 121, 121' on the top and bottom with numbers from 0 to 9 (not shown) engraved at equal intervals on their outer surfaces. Each dial 121, 121' is rotatably supported at predetermined intervals by a pair of upper and lower protrusions 15, 15' protruding from the inner surface of the side panel 8c of the case main body 8. A portion of the outer periphery of each dial 121, 121' protrudes slightly outward from openings formed in the front panel 8a and rear panel 8b so that it can be rotated from outside the case main body 8.

[0020] Ten grooves 121a, 121a' are formed at predetermined intervals on the outer circumferential surface of each dial 121, 121', and four flexible latch pieces 16a, 16a' at the top and bottom of vertical rods 16, 16' screwed to the inner surface of side panel 8c (see Figure 3) are designed to elastically engage and disengage with each groove 121a, 121a'. As a result, each dial 121, 121' is designed to stop in stages at positions where the engraved faces of the numbers from 0 to 9 can be seen from the outer surfaces of front panel 8a and rear panel 8b.

[0021] Movable members 17, 17' bent like a crank in plan view are fixed to the ends of the inner and outer operating units 11, 11' that protrude inward from the front panel 8a and rear panel 8b, so that they can appear and disappear into the box body 2 through slits 9a, 9a' formed in the side cover 9 by rotating the operating units 11, 11' (see Figure 2). The inner and outer movable members 17, 17' are connected to each other by a connecting member 18 that extends inward and outward, so that, for example, when the outdoor operating unit 11 is operated to rotate the movable member 17, the movable member 17' of the indoor operating unit 11' also rotates in conjunction with this.

[0022] The inner and outer movable members 17, 17' are adapted to engage with and disengage from locking grooves (see locking groove 6a of outer door 6 shown in Figure 6) formed in the outer door 6 and inner door 7 opposite them, and when the movable members 17, 17' protrude from the side cover 9, the outer door 6 and inner door 7 cannot be opened simultaneously (i.e., closed door state), and when the movable members 17, 17' retract from the side cover 9, the outer door 6 and inner door 7 can be opened simultaneously (i.e., door-openable state).

[0023] 5, a large diameter shaft hole 122 with a bottom and a small diameter shaft hole 123 that penetrates vertically are formed in the center of each outdoor dial lock 12, and ten locking grooves 123a are formed on the inner peripheral surface of the small diameter shaft hole 123 at regular intervals in the circumferential direction to correspond to the engraved surface of the dial 121. A small diameter shaft portion 191 at the bottom of the stepped shaft 19 is fitted into the small diameter shaft hole 123 of each dial 121 so as to be relatively rotatable and movable up and down, and the lower end of a large diameter shaft portion 192 at the top of the stepped shaft 19 is fitted into the large diameter shaft hole 122 so as to be rotatable freely.

[0024] The lower end surface of the large diameter shaft portion 192 is supported by a step surface 124 between the large diameter shaft hole 122 and the small diameter shaft hole 123, which restricts downward movement of the stepped shaft 19 relative to the dial 121. Ten protrusions 192a protrude downward from the lower surface of the large diameter shaft portion 192 and can be fitted into and disengaged from above into ten locking grooves 123a in the dial 121. A roughly 90-degree cam groove 192b is formed on the outer circumferential surface of the large diameter shaft portion 192 with which a latch 144 (described later) provided on the movable switching member 14 engages and disengages.

[0025] A shaft hole 193 is formed in the center of each stepped shaft 19, penetrating in the vertical direction, and support shafts 20 extending in the vertical direction are fitted into this shaft hole 193 so as to be relatively rotatable, allowing the four upper and lower stepped shafts 19 to rotate around the support shafts 20. The four upper and lower stepped shafts 19 are fitted between two upper and lower E-rings (not shown) fitted onto the support shafts 20, with their opposing surfaces abutting against each other. This allows all of the stepped shafts 19 to move up and down together with the support shafts 20. The upper ends of the support shafts 20 are supported by a support portion 21 integrally provided on the upper end of the inner surface facing the outdoor side of the case body 8 so as to be able to move up and down (see FIG. 3), and the lower ends of the support shafts 20 are supported by a support portion (not shown) integrally provided on the lower end of the inner surface facing the outdoor side of the case body 8 so as to be able to move up and down.

[0026] As shown in FIG. 3, a compression coil spring 22 is inserted into the support shaft 20 between the upper support portion 21 and the uppermost stepped shaft 19, constantly urging all of the stepped shafts 19 downward. As shown in FIG. 6, the lower ends of the support shafts 20 are located directly above the cam plate 17a connected to the outdoor-side movable member 17. As a result, all of the stepped shafts 19 are urged downward by the compression coil spring 22, and all of the protrusions 192a on the lower surface of the large-diameter shaft portion 192 fit into all of the locking grooves 123a of the dial 121, so that the stepped shafts 19 rotate integrally with the rotation of the dial 121. The cam plate 17a and the support shafts 20 are constantly in contact, and when the operating unit 11 is turned, the lower end of the support shaft 20 hits the flat surface of the cam plate 17a, creating a clicking sensation during operation and enabling easy fixing of the support shafts 20.

[0027] 6(b), when the outdoor operating unit 11 is rotated to rotate the movable member 17 90 degrees to the unlocked position, the top surface of the cam plate 17a pushes up the support shaft 20 against the compression coil spring 22, and all of the stepped shafts 19 move upward. As a result, the protrusions 192a of each stepped shaft 19 are released from the locking grooves 123a of the dials 121, and the rotation of the dials 121 is no longer transmitted to the stepped shafts 19, allowing only the dials 121 to rotate.

[0028] 3 and 4, the four indoor dials 121' are formed with shaft holes (not shown) similar to the small diameter shaft hole 123 of the outdoor dial 121, and a support rod 23 extending in the vertical direction is fitted into this shaft hole so as to be rotatable relative to the dials 121', thereby supporting all of the dials 121' by the support rod 23. A support shaft 20' similar to the one on the outdoor side is fitted into a shaft hole (not shown) formed in the center of the support rod 23 so as to be rotatable relative to the dials 121', and vertical movement of the support rod 23 is restricted by E-rings (not shown) fitted onto the outer peripheral surfaces of the upper and lower parts of this support shaft 20'.

[0029] The upper end of the support shaft 20' is supported by a support part 21' integrally provided on the upper end of the indoor-side inner surface of the case body 8 so as to be movable up and down (see FIG. 3), and the lower end of the support shaft 20' is supported by a support part 24 integrally provided on the lower end of the indoor-side inner surface of the case body 8 so as to be movable up and down. A compression coil spring 22' similar to that on the outdoor side is inserted into the support shaft 20' between the upper surface of the support rod 23 and the support part 21', and the support rod 23 and the support shaft 20' are constantly biased downward. As on the outdoor side, the lower end of the support shaft 20' is located directly above a cam plate (not shown) that rotates when the indoor-side operating unit 11' is rotated. When the operating unit 11' is rotated 90 degrees to the unlock position, the cam plate pushes up the support shaft 20' and support rod 23 together against the compression coil spring 22'.

[0030] As shown in Figures 3 and 4, the interlocking means 13 comprises driving gears 131, 131' integrally formed on the undersides of the inner and outer dials 121, 121' near the outer periphery; four upper and lower interlocking rods 132 extending inward and outward; and a pair of inner and outer driven gears (bevel gears) 133, 133' fixed to both ends of each interlocking rod 132 and meshing with the driving gears 131, 131' of each dial 121, 121'. The inner and outer dials 121, 121' are connected to the interlocking means 13 in phase with each other so that the rotational positions of the numbers engraved on them are the same. Both ends of each interlocking rod 132 are rotatably supported by a pair of upper and lower support pieces 25, 25' protruding from the inner surface of the case body 8. With this interlocking means 13 configured as above, for example, when the outdoor dial 121 is rotated, the indoor dial 121' is also rotated.

[0031] 3, 4, and 7, the movable switching member 14 provided on the outdoor side includes a cylindrical support shaft 141 extending vertically and disposed to the right of each of the outdoor dials 121, a locking portion 142 extending from the lower end of the support shaft 141 toward the indoor side, a latch base 143 extending from the support shaft 141 toward the indoor side above the locking portion 142, and four latches 144 provided at upper and lower positions adjacent to the indoor end of the latch base 143 at predetermined intervals. The support shaft 141 is rotatably supported by supports 26, 26 protruding from the upper and lower inner surfaces of the front panel 8a of the case body 8, so that the movable switching member 14 can rotate horizontally around the support shaft 141 (see FIG. 7).

[0032] A right-triangular protrusion is formed at the tip of each of the four latches 144, and is capable of fitting into and disengaging from the cam grooves 192b of the large-diameter shaft portions 192 of the four upper and lower stepped shafts 19. A hook 142a is connected to the lower end of the locking portion 142, and is configured to engage with and disengage from the lower end of the connecting member 18. The movable switching member 14 is constantly biased horizontally to the left (in the direction in which the protrusion of the latch 144 engages with the cam groove 192b) by a tension coil spring 30 disposed between the locking portion 142 and the inner surface of the case main body 8.

[0033] As shown in FIG. 7(a), when any of the four latches 144 is disengaged from at least one of the cam grooves 192b (the uppermost cam groove in the figure) of the four large-diameter shaft portions 192 and the latch 144 is in contact with the outer circumferential surface of the large-diameter shaft portion 192 (see FIG. 8(a) for details), the movable switching member 14 rotates toward the connecting member 18, and the hook 142a of the locking portion 142 engages with the connecting member 18. This restricts the downward rotation of the connecting member 18 and the inner and outer movable members 17, 17', placing the movable switching member 14 in a door-open restricted state and disabling rotation of the inner and outer operating portions 11, 11' in the door-open direction. As a result, the inner and outer movable members 17, 17' are held in a protruding state, and the outer door 6 and inner door 7 are in a closed state.

[0034] On the other hand, as shown in Figure 7(b), when the four upper and lower latches 144 are engaged with all four cam grooves 192b (see Figure 8(b) for details), the movable switching member 14 is rotated in the opposite direction to the connecting member 18 by the tension coil spring 30, and the hooks 142a of the locking portions 142 are released from the connecting member 18. This allows the connecting member 18 and the inner and outer movable members 17, 17' to rotate downward, and the inner and outer operating portions 11, 11' can be rotated in the door-opening direction. As a result, when the inner and outer operating portions 11, 11' are rotated in the door-opening direction, the inner and outer movable members 17, 17' rotate downward from their protruding state, and the outer door 6 and inner door 7 are unlocked simultaneously. In addition, when the hook 142a of the locking portion 142 is disengaged from the connecting member 18 and the movable switching member 14 is in the door-opening restriction release state, the inner and outer operating portions 11, 11' can be freely rotated in the door-opening direction and the door-closing direction, and therefore the outer door 6 and the inner door 7 can be opened by rotating the movable members 17, 17' in the vertical direction. Therefore, in this state, the delivery person can open the outer door 6 and store the delivery item in the box body 2.

[0035] As shown in FIGS. 1 and 3 , a cylinder lock 27 is attached to the lower end of the front panel 8a of the case body 8 in case of an emergency when the outer door 6 or the inner door 7 cannot be unlocked by the dial locks 12, 12′. When the cylinder lock 27 is unlocked with a key, an unlock lever 28 is activated, and the movable switching member 14 is set to the door-opening restriction release state. This allows the outer door 6 and the inner door 7 to be opened by the cylinder lock 27 even if the personal identification number of the dial locks 12, 12′ is forgotten. More specifically, the lower end of the unlock lever 28, which extends upward and has four emergency unlocking keys (not shown) attached to a rotating shaft (not shown) of the cylinder lock 27 that protrudes into the case body 8, is attached. When the cylinder lock 27 is unlocked with a key, the unlock lever 28 is activated, and the emergency unlocking key abuts against the small-diameter shaft portion 191 of the stepped shaft 19. A locking groove (not shown) is formed in the small diameter shaft portion 191, and when the dial 121 is rotated, the tip of the emergency unlocking key fits into the locking groove of the small diameter shaft portion 191 at the unlocking number on that dial 121, disabling the rotation of that dial 121. After performing the same procedure for all dials 121, the key is removed from the cylinder lock 27 and the operating part 11 is rotated, allowing the outer door 6 and inner door 7 to be opened.

[0036] Next, a description will be given of an example of how to use the delivery box 1 according to the embodiment. With the outer door 6 and inner door 7 unlocked, a delivery person opens the outer door 6, places the parcel in the box body 2, and then closes the outer door 6 (without locking it yet).

[0037] Next, the dials 121 of the outdoor combination lock 12, which has been released from engagement with the stepped shaft 19 and can rotate independently, are rotated to set a PIN number, and then the outdoor operation unit 11 is rotated in the locking direction to cause the movable member 17 to protrude toward the box body 2. The PIN number set by the delivery company is written on a notification slip or the like and placed in the recipient's mailbox installed at the entrance, or is transmitted to the recipient's mobile terminal or the like.

[0038] In this state, when the outdoor operating unit 11 is rotated in the locking direction, the dials 121 and the stepped shaft 19 engage and become rotatable together. Therefore, by appropriately rotating at least one dial 121 to disengage the latch 144 of the movable switching member 14 from the cam groove 192b of the large-diameter shaft portion 192, the rotation of the movable switching member 14 is restricted and the downward rotation of the movable member 17 and the connecting member 18 is prevented (see Figures 7(a) and 8(a)). This keeps the movable member 17 in a protruding state and allows the outer door 6 to be locked. Note that, since the indoor dials 121' rotate in conjunction with each other via the interlocking means 13, the PIN number of the indoor dial lock 12' is set to the same number as that of the outdoor dial lock 12. Furthermore, since the indoor operating unit 11' and the movable member 17' also rotate in conjunction with each other in the locking direction via the connecting member 18, the inner door 7 is also locked at the same time.

[0039] When the recipient wishes to retrieve a package, they rotate the dials 121, 121' of either the inner or outer dial locks 12, 12' based on the set PIN number, causing all of the latches 144 of the movable switching member 14 to engage with all of the cam grooves 192b of the large diameter shaft portion 192 (see Figures 7(b) and 8(a)). This releases the lock, and by rotating either the inner or outer operating member 11, 11' in the door-opening direction, the inner and outer movable members 17, 17' rotate downward, opening both the outer door 6 and the inner door 7. This means that the package can be retrieved from either the outdoor opening 4 or the indoor opening 5.

[0040] As described above, in the delivery box 1 of this embodiment, the pair of inner and outer dial locks 12, 12' that set the door-opening restricted state or the door-opening restricted released state for switching the movable switching member 14 to the door-opening restricted state or the door-opening restricted released state are linked by the linking means 13, so that, for example, when the outdoor dial lock 12 is unlocked based on the PIN number from the delivery company, the indoor dial lock 12' is also unlocked at the same time, and both the outer door 6 and the inner door 7 are placed in an openable state. Therefore, by rotating either the inner or outer operating unit 11 in the door-opening direction, the delivery item can be retrieved from either the outdoor opening 4 or the indoor opening 5, eliminating the need to go outside the building to retrieve the delivery item.

[0041] Furthermore, the movable members 17, 17' attached to the inside and outside operating units 11, 11' are connected to each other by a connecting member 18 extending in the inside-outside direction, so that, for example, when the outdoor operating unit 11 is operated to rotate the movable member 17 and place the outer door 6 in a closed state or an openable state, the movable member 17' of the indoor operating unit 11' can also be rotated in conjunction with the operating unit 11' by the connecting member 18, and the inner door 7 can be placed in a closed state or an openable state. Therefore, when taking out a parcel from the outdoor opening 4 or the indoor opening 5, there is no need to operate the inside and outside operating units 11, 11' individually.

[0042] In addition, by engaging and disengaging the movable switching member 14 provided on the outdoor side with the connecting member 18 connecting the inside and outside movable members 17, 17', the door can be switched simultaneously between the door-opening restricted state and the door-opening restricted released state, so that only one movable switching member 14 is required, thereby reducing costs.

[0043] In addition, the interlocking means 13 that interlocks the inner and outer dial locks 12, 12' is composed of driving gears 131, 131' provided on the inner and outer dials 121, 121', an interlocking rod 132 extending inward and outward directions, and driven gears 133, 133' attached to both ends of the interlocking rod 132 and meshing with the inner and outer driving gears 131, so that the rotation of one dial lock 12 is reliably transmitted to the other dial lock 12', allowing the inner and outer dial locks 12, 12' to be reliably interlocked.

[0044] Furthermore, the operating parts 11, 11', dial locks 12, 12', interlocking means 13, movable switching member 14, connecting member 18, etc. that make up the locking / unlocking mechanism 10 are assembled into the case main body 8 to form a locking / unlocking unit 3, and this locking / unlocking unit 3 can simply be attached to the box main body 2, thereby reducing the assembly labor and making it easy to manufacture the delivery box 1.

[0045] The delivery box of the present invention has been described above based on an embodiment, but the specific configuration is not limited to this embodiment, and various modifications and changes such as those listed below are also included in the present invention as long as they do not deviate from the gist of the present invention.

[0046] In the above embodiment, the movable switching member 14 is provided only on the outdoor side, and the stepped shaft 19, to which the latch 144 of the movable switching member 14 engages and disengages, is provided on the dial 121 of the combination lock 12, but this is not limitative and these members may also be provided on the indoor side. In this way, the connecting member 18 can be omitted, and the outer door 6 and the inner door 7 can be locked and unlocked by individually operating the inner and outer operating parts 11, 11'. In this case, a hook that can directly engage and disengage with the inner and outer movable members 17, 17' can be provided at the lower end of the inner and outer movable switching member 14.

[0047] Furthermore, in the above embodiment, the interlocking means 13 is composed of driving gears 131, 131' provided on the inner and outer dials 121, 121', four interlocking rods 132, and driven gears 133, 133' fixed to both ends of each interlocking rod 132 so as to mesh with the driving gears 131, 131'. However, this is not limiting, and for example, pulleys or sprockets may be integrally attached to the inner and outer dials 121, 121', and belts or chains may be wound around them to interlock the inner and outer dials 121, 121'.

[0048] In the above embodiment, the operating units 11, 11', dial locks 12, 12', interlocking means 13, movable switching member 14, and connecting member 18 that constitute the locking / unlocking mechanism 10 are assembled to the case body 8 to form the locking / unlocking unit 3, but each of the above components can also be assembled directly to one side of the box body 2. Furthermore, the locking / unlocking unit may be configured such that the front elements other than the interlocking means are a locking unit in the case, and similarly the rear elements other than the interlocking means are a locking unit in the case, with the interlocking unit including the interlocking means and the case being separate units. This makes it easier to respond on-site if the dial lock number is misaligned and makes it easier to flexibly accommodate different sizes of delivery boxes.

[0049] The locking / unlocking unit 3 may be configured to further have a separate cover attached thereto having the same size as the height dimension of the box body 2 so that it can be used for box bodies 2 having different height dimensions. [Explanation of symbols]
