[0003] [Patent Document 1] JP 2017-198360 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, adding a refrigeration function to an existing parcel locker that does not have a refrigeration function to store parcels at low temperatures would require a large change in equipment from the existing parcel locker, which could lead to increased costs. Also, if a lock is installed on the door of the parcel locker, depending on the type of lock, the cooling performance inside the locker could be impaired.

[0005] The object of the present disclosure is to provide a parcel locker with a cooling function that can be easily realized using existing structures and that can prevent impairment of the cooling performance of the luggage compartment regardless of the type of locking mechanism. [Means for solving the problem]

[0006] The delivery locker with cooling function disclosed herein is a delivery locker with a refrigeration function comprising a case body having an opening on the front, a cooling device for cooling the inside of the case body, a plurality of luggage compartments provided inside the case body and capable of accommodating luggage, a plurality of case doors supported by the case body so as to cover the openings of the plurality of luggage compartments, and a plurality of doors with locking sections arranged on the outside of each of the plurality of case doors and regulating the opening of each of the plurality of case doors. Effect of the Invention

[0007] According to the refrigerated delivery locker of the present disclosure, a refrigerated delivery locker can be easily realized by using an existing box with a refrigeration function, which includes a case body with an opening on the front and a cooling device that cools the inside of the case body, supporting multiple case doors and multiple doors with locking units on the case body, and arranging multiple doors with locking units on the outside of the multiple case doors. Moreover, since there is no need to provide locking units on the case doors, it is possible to prevent the installation of the case doors from impeding the cooling performance inside the case body, regardless of the type of locking unit.

[0009] Hereinafter, an embodiment of the present disclosure will be described with reference to the drawings. The shapes, materials, and quantities described below are examples for the purpose of explanation, and can be changed as appropriate according to the specifications of the refrigerated delivery locker. In the following, the same elements in all drawings will be assigned the same reference numerals. In addition, in the explanations in the text, the reference numerals previously described will be used as necessary.

[0010] In the following explanations and drawings, R is the right side when viewed from outside the refrigerated delivery locker toward the front where the case door is with the case door closed, L is the left side, F is the front side that is the front side of the refrigerated delivery locker, and B is the rear side that is the back side of the refrigerated delivery locker. The direction connecting R and L and the direction connecting F and B are mutually perpendicular.

[0011] FIG. 1 is a schematic perspective view of a parcel locker 12 with a refrigerated function according to an embodiment. FIG. 2 is a schematic AA cross-sectional view for explaining the basic configuration of the parcel locker 12 with a refrigerated function. The parcel locker 12 with a refrigerated function is installed in a common area such as an entrance hall of a collective housing complex such as an apartment building, in a store, or in a public facility such as a station, and can receive parcels (not shown) delivered without any person present. In particular, when the parcels delivered are parcels such as food or medicine that require refrigeration, the structure of this example is highly effective. The parcel locker 12 with a refrigerated function allows a parcel delivery person to deposit the parcel and lock the door 60 with a locking unit, so that only the recipient of the parcel who can unlock the door can take out the parcel. In the following, the "parcel locker 12 with a refrigerated function" will be referred to as the "parcel locker 12".

[0012] First, the basic configuration of the parcel locker 12 will be described. The parcel locker 12 includes a substantially rectangular parallelepiped base box 14 that is installed on the ground, floor, etc., a substantially rectangular parallelepiped case body 18 that is installed on the base box 14, and a cooling device 15 that is installed in the base box 14. A plurality of legs 16 are fixed to the bottom surface of the base box 14. Two luggage compartments 19, 20 that are separated into upper and lower compartments are provided inside the case body 18. The two luggage compartments 19, 20 are separated by a partition section 21. The partition section 21 is, for example, a metal mesh shelf. The partition section 21 may be a plate section that has a plurality of through holes formed in the vertical direction. The two luggage compartments 19, 20 need to be cooled by cooling air supplied from the cooling device 15 installed in the base box 14, so the partition section 21 is formed in a shape that allows air to circulate between the two luggage compartments 19, 20.

[0013] The case body 18 is composed of four pillars 22, 23, 24, 25 erected at the four corners of the upper surface of the base box 14, a ceiling portion 50 fixed to the upper ends of the four pillars 22, 23, 24, 25, and three transparent or translucent glass plates 51 connected between two adjacent pillars 22, 23, 24, 25 and forming the right side, left side and rear side of the case body 18.

[0014] As shown in FIG. 2, each of the supports 22, 23, 24, 25 is formed by combining a resin frame 26 that holds a glass plate 51 with a metal frame 30 made of iron or the like that is attached adjacent to the resin frame 26 and reinforces the resin frame 26.

[0015] The cooling device 15 may be formed by a refrigeration cycle device having, for example, an evaporator, a compressor, a condenser, a blower, etc., which cools air passing through the evaporator by circulating a refrigerant. The air cooled by the cooling device 15 may be circulated to the two luggage compartments 19, 20 by a blower, thereby cooling the two luggage compartments 19, 20.

[0016] Furthermore, the parcel locker 12 includes two case doors 40, 41 supported on the case body 18 so as to be openable and closable so as to close the openings 18a of the two luggage compartments 19, 20, which are openings on the front surface of the case body 18, and two lockable doors 60 supported on the case body 18 by hinges so as to be disposed on the outsides of the two case doors 40, 41. When in a closed state, each of the lockable doors 60 restricts the opening of the corresponding inner case door 40, 41.

[0017] Each of the case doors 40 and 41 is made of four resin case frames 42, 43, 44, and 45 that form the four sides of a substantially rectangular shape, and a glass plate held on the inner periphery of the four case frames 42, 43, 44, and 45. 52 The case doors 40, 41 each have a hinge hole 47 (FIG. 2) at the upper and lower ends of the right end portion. A hinge pin P1 (FIG. 2) fixed to the case body 18 directly or via another member is inserted into the hinge hole 47. This allows each case door 40, 41 to be supported so as to be openable and closable relative to the case body 18. Furthermore, a magnet 48 (FIG. 2) is fixed to each case door 40, 41 at a portion facing the metal frame 31 forming the left end support 23 provided at the front end of the case body 18. This allows each case door 40, 41 to be maintained in a closed state with the magnet 48 magnetically attracted to the metal frame 31 with the front end openings of the luggage compartments 19, 20 closed.

[0018] Furthermore, one end of a hinge 70 (FIG. 2), which is the mounting portion of the locking door 60, is fixed to the outer surface on the right side of the support pillar 22 erected at the right end of the front side of the case body 18. In each of the locking doors 60, the right end portion, which is the hinge 70 connecting side end of the case doors 40, 41, is connected to the hinge 70. As a result, each of the locking doors 60 is supported by the case body 18 via the hinge 70. Therefore, each of the locking doors 60 can be opened widely, such as about 180 degrees, around the rotation axis P2 of the hinge 70, which is located behind the hinge pin P1, which is the rotation axis of the case doors 40, 41, without restricting the opening of the case doors 40, 41.

[0019] Further, each door with a locking section 60 has a locking device 61 as a locking section having a locking device with a keyhole and a receiving section for receiving a wireless signal. The locking device 61 is an electronic lock that allows the door with a locking section 60 to be electrically locked and unlocked, and has a latch 62 that can be advanced and retreated into a locking hole of a lock plate 80 fixed to the case body 18 when the door with a locking section 60 is in a closed state, and a locking mechanism (not shown) that prevents the latch 62 from retreating. The locking mechanism switches between lock and unlock when a key is inserted into the keyhole of the locking device and turned, or when a wireless signal indicating that the door is locked or unlocked is received by the receiving section from a card key or a mobile terminal such as a smartphone. In the locked state of the locking device 61, the latch 62 is prevented from retreating from the locking hole, thereby locking the door with a locking section 60. In this state, the door with a locking section 60 restricts the opening of the inner case doors 40, 41. In the unlocked state of the locking device 61, the latch 62 is permitted to retract from the locking hole, thereby unlocking the locking door 60. This causes the locking door 60 to open, and in this state, the case doors 40 and 41 can be opened.

[0020] Fig. 3 is a perspective view of an existing box with cooling function 100 used to realize delivery locker 12. The delivery locker 12 described above can be easily realized by utilizing the existing box with cooling function 100 shown in Fig. 3. Box with cooling function 100 is, for example, an existing refrigerated showcase that includes a case body 18 in which the outside of a storage chamber 101 provided therein is surrounded by glass plates 51 that form the right side, left side, and rear side, and in which one or more partition sections 21 are provided inside storage chamber 101. Box with cooling function 100 may have a plurality of partition sections provided inside storage chamber 101.

[0021] Such a box 100 with cooling function is widely used, and can be easily used to realize the parcel locker 12. The box 100 with cooling function is common to the parcel locker 12 in that it includes a case body 18 having an opening on the front side and a cooling device 15 for cooling the inside of the case body 18. Meanwhile, unlike the parcel locker 12, the box 100 with cooling function has only one large case door 102 that is supported by the case body 18 so as to be openable and closable so as to cover the opening at the front end of the case body 18. The case door 102 is formed by attaching frame members (not shown) to the four sides of a substantially rectangular plate glass 103, and is hinged to the case body 18. A magnet (not shown) is fixed to the left end of the case door 102, at a portion facing the metal frame of the case body 18. The magnet is attracted to the metal frame when the case door 102 is closed, thereby maintaining the case door 102 in a closed state.

[0022] When realizing the delivery locker 12 of this embodiment using the above-mentioned box 100 with cooling function, the case door 102 and the two support pillars 22, 23 arranged on both the left and right ends of the front end are removed from the front side of the box 100 with cooling function. Then, the structure including the two support pillars 22, 23 at the front end, the two case doors 40, 41, and the two locking door 60 shown in FIG. 1 is made into the door unit 13 (FIG. 4), and the door unit 13 is combined with a structure without the two support pillars 22, 23 at the front end of the case main body 18. This makes it possible to realize the delivery locker 12 in which the two case doors 40, 41 are supported on the front side of the case main body 18, and the two locking door 60 are further supported on the front side thereof.

[0023] The configuration of the door unit 13 will be described in more detail below with reference to Figs. 4 to 13. Fig. 4 is a perspective view of the door unit 13 as seen from the front side. Fig. 5 is a perspective view of the door unit 13 as seen from the front side. Fig. 6 is a perspective view of the door unit 13 as seen from the rear side. Fig. 7 is an enlarged perspective view of the upper part of Fig. 6.

[0024] The door unit 13 is configured to include two support pillars 22, 23 arranged at the front end of the case body 18, two case doors 40, 41, and two doors 60 with locking parts. As shown in FIG. 7, the two support pillars 22, 23 are configured to include resin frames 26, 27 and metal frames 30, 31. The metal frames 30, 31 are members having an L-shaped cross section and elongated in the vertical direction. The metal frames 30, 31 can be joined to the adjacent resin frames 26, 27 on the inside in the left-right direction by bonding or screwing. In FIG. 6, as shown representatively by the right support pillar 22, each support pillar 22, 23 has locking holes 26a for locking locking parts (not shown) provided on the partition part 21 (FIG. 1) at multiple positions in the vertical direction on the inner side surface in the left-right direction of the resin frame 26 forming the support pillar 22. The left and right ends of a horizontally long, substantially box-shaped intermediate bracket 71 with an open rear end are screwed to the vertical intermediate portions of the two resin frames 26, 27. This connects the two resin frames 26, 27, thereby improving the strength of the two supports 22, 23.

[0025] Fig. 8 is a view seen from above in Fig. 6. Fig. 9 is an enlarged view of part B in Fig. 8, and Fig. 10 is an enlarged view of part C in Fig. 8. Each of the resin frames 26, 27 has insertion parts 26b, 27b at the outer left and right ends, the insertion parts 26b, 27b having a generally U-shaped cross section with an open rear end. Glass plates 51 (Fig. 1) arranged at both left and right ends of the case body 18 are inserted and fixed into each of the insertion parts 26b, 27b.

[0026] 4 and 5, each of the case doors 40, 41 includes four resin case frames 42, 43, 44, 45 that respectively form the four sides of a substantially rectangular shape, and a glass plate 52 held in grooves (not shown) formed on the inner periphery of the four case frames 42, 43, 44, 45. The two case doors 40, 41 face each other with a gap in between in the vertical direction.

[0027] Meanwhile, a substantially rectangular intermediate plate 72 is fixed across the front ends of the two resin frames 26, 27 in portions facing the front side of the intermediate bracket 71. The upper end of the intermediate plate 72 faces closely to or contacts the rear side of the case frame 45 at the lower end of the upper case door 40. The lower end of the intermediate plate 72 faces closely to or contacts the rear side of the case frame 42 at the upper end of the lower case door 41. This prevents cool air from inside the luggage compartments 19, 20 (FIG. 1) from leaking out to the outside through the gap between the two case doors 40, 41.

[0028] A hinge plate 73 is fixed to the outer ends in the up-down direction of the right ends of the two case frames 42, 45 located on the upper end surface of the upper case door 40 and the lower end surface of the lower case door 41. An outer hinge hole 74 that penetrates vertically is formed in the right end of the hinge plate 73. A hinge pin P1 (FIG. 2) fixed to the ceiling part 50 (FIG. 1) of the case body 18 is inserted into the outer hinge hole 74 of the upper case door 40.

[0029] An inner hinge hole (not shown) is formed at the inner end of the right end of the two case frames 45, 42 located on the lower end surface of the upper case door 40 and the upper end surface of the lower case door 41, penetrating vertically. A hinge pin (not shown) protruding in the vertical direction from a pin support part 75 (FIG. 4) fixed to the front end plate part 30a (FIG. 9) of the metal frame 30 at the right end is inserted into the inner hinge hole. The inner hinge hole and the outer hinge hole 74 are located on the same axis line along the vertical direction. As a result, each case door 40, 41 is supported by the case main body 18 so as to be able to open and close. A magnet 48 (FIG. 2) for maintaining the door closed state is fixed to a part of the rear side surface of the left end part of each case door 40, 41 facing the metal frame 31 at the left end. A rubber packing may be attached to the rear side of each case frame 42, 43, 44, 45 of case doors 40, 41 to press against the front faces of the front end supports 22, 23 when the doors are closed, thereby ensuring airtightness when the doors are closed.

[0030] As shown in Fig. 13, which will be described later, a lock plate 80 is fixed by screws to the left side surface of the left-most metal frame 31 so as to protrude forward. A locking hole 80a is formed in the front end of the lock plate 80, into which the tip of a latch 62 of a locking device 61, which will be described later, can be inserted. As shown in Figs. 6 and 7, the periphery of the lock plate 80 (Fig. 13) is covered by a case-shaped lock plate holder 76 fixed to the left side surface of the left-most metal frame 31.

[0031] FIG. 11 is a view of the upper part of the door unit 13 seen from the right side. FIG. 12 is a perspective view showing a state in which the door body 63 of the upper locking door 60 is separated from the door unit 13. One end of the two hinges 70 is fixed to the right side surface of the metal frame 30 at the right end via two upper and lower fixed side hinge plates 77. The door side hinge plate 64 constituting the locking door 60 is fixed to the other end of the hinge 70 via a screw. The locking door 60 is composed of the door side hinge plate 64, the door body 63 fixed to the front side of the door side hinge plate 64, and the locking device 61 attached to the door body 63. When the locking door 60 is in a closed state, the door side hinge plate 64 faces the glass plate 52 of the case doors 40, 41 in a closed state. The right part of the door body 63 is fixed to the front side of the door side hinge plate 64 via a bracket 65.

[0032] The door body 63 is generally box-shaped with an opening at the rear end, and a generally rectangular opening 63b is formed on the left side of the plate portion 63a at the front end. The locking device 61 is fixed in a state where it is housed in the right part of the door body 63, and in this state, the front surface of the locking device 61 is exposed to the front side of the door body 63 through the opening 63b.

[0033] As shown in FIG. 13, the locking device 61 includes a casing 61a fixed to a door body 63, a latch handle 61b rotatably supported on the casing 61a, a locking device 61c having a keyhole, a receiver 61d for receiving a wireless signal, a latch 62 that protrudes from the left end of the casing 61a or retracts inward in conjunction with the latch handle 61b, and a locking mechanism (not shown) for preventing the retraction of the latch 62. When the door 60 with a locking unit is in a closed state, the latch 62 can advance and retract into the locking hole 80a of the lock plate 80 fixed to the case body 18. The locking mechanism prevents the latch 62 from retracting by using the locking device 61c or the receiver 61d as described above, and closes the door 60 with a locking unit. As a result, the door 60 with a locking unit is coupled to a hinge 70 fixed to the outer surface on the right side of the support 22 erected at the right end of the front side of the case body 18. For this reason, each locking door 60 is supported on the case body 18 via a hinge 70. Furthermore, the locking door 60 is disposed outside the case doors 40, 41, and in the closed state, restricts the opening of the inner case doors 40, 41.

[0034] Furthermore, the locking device 61 includes a power supply unit including a battery, a control unit to which power is supplied from the power supply unit, and an electric actuator driven by the control unit, although illustration is omitted. The electric actuator constitutes a locking mechanism, and switches the latch 62 between a locked state and an unlocked state in response to a signal received by the receiving unit 61d. For example, after a delivery person or the like places a package that requires cooling in the luggage compartment 19, 20 (FIG. 1), the delivery person can close the case doors 40, 41 and the door with a locking unit 60, and lock the door with a locking unit 60 by transmitting a signal representing predetermined identification information and a signal representing locking to the receiving unit 61d using a mobile terminal. A user on the receiving side of the package can unlock the door with a locking unit 60 by transmitting a signal representing predetermined identification information and a signal representing unlocking to the receiving unit 61d using a mobile terminal. The wireless signal received by the receiving unit 61d may be a signal of the BLE standard.

[0035] The locking device 61 may be provided with a numeric keypad input section, and the locking door 60 may be locked or unlocked by pressing a PIN number on the numeric keypad input section. Also, the configuration of this example may be configured such that the locking door 60 can be locked or unlocked only by turning a key inserted into a keyhole of the locking device 61c, without providing an electronic lock. The locking device may also be configured such that the locking door can be locked or unlocked by a combination lock.

[0036] According to the above-mentioned delivery locker 12, delivery locker 12 can be realized by utilizing an existing box with cooling function 100 equipped with case body 18 having an opening on the front and cooling device 15 that cools the inside of case body 18, supporting multiple case doors 40, 41 and multiple locking doors 60 on case body 18, and arranging multiple locking doors 60 on the outside of multiple case doors 40, 41. In this way, delivery locker 12 can be easily realized, unlike a case in which a cooling function is provided to an existing delivery locker that does not have a cooling function.

[0037] Moreover, since there is no need to provide a locking section on each of the case doors 40, 41, regardless of the type of locking section, for example, the presence or absence of an electronic lock, it is possible to prevent the installation of each of the case doors 40, 41 from impairing the cooling performance inside the case body 18. For example, when the locking section is an electronic lock, depending on the type of electronic lock, heat may be generated when electricity is applied, so providing a locking section on the case door may impair the cooling performance inside the case body 18. In the embodiment, the locking device 61 is provided on the door 60 with a locking section, which is located outside the case doors 40, 41, so this kind of inconvenience can be prevented.

[0038] The door with a lock does not open or close the opening of the case body 18, but only needs to have a function of restricting the opening of the case doors 40, 41. For example, the door with a lock may be a bar-shaped member whose vertical height is considerably smaller than that of the case doors 40, 41, and which restricts the opening of the case doors 40, 41.

[0039] Also, in the above embodiment, a case has been described in which the door unit 13 is combined with a structure that does not have two support pillars at the front end of the case body 18 of an existing box with cooling function 100. On the other hand, the two support pillars 22, 23 at the front end of an existing box with cooling function 100 may be used as is, and a delivery locker with a refrigeration function may be realized by fixing a lock plate 80, a hinge 70, or the like to the two support pillars 22, 23.

[0040] In addition, in the configuration of the present disclosure, the case body and case door of the refrigerated delivery locker are not limited to a configuration having glass plates, and the sides of the case body and the case door may be formed from plate members that are not optically transparent.

[0041] Furthermore, the refrigerated delivery locker disclosed herein is not limited to a configuration having only two luggage compartments as in the above embodiment, but may have a configuration having three or more luggage compartments. [Explanation of symbols]
