Description

[Technical field]

[0001] The present disclosure relates to a delivery box. [Background technology]

[0002] Conventionally, in delivery boxes for detached houses, a structure has been used in which the lock is locked when a package is received, and the locking part is unlocked with a dedicated physical key or a PIN number. Patent Document 1 describes a locking device for a storage box, which includes a latch member (latch part) housed in a case having a first side wall part and a second side wall part, a slide member having an operating lever (knob part) protruding forward, which is capable of moving the latch member biased toward the first side wall part toward the second side wall part, and a restrictive lock member that restricts the movement of the slide member, and a configuration in which the restriction by the restrictive lock member is released by the lock main body. In this configuration, a knob part that interlocks with the latch member is provided, and the movement of the knob part is restricted when the lock is engaged.

[0003] [Patent Document 1] JP 2019-90168 A Summary of the Invention [Problem to be solved by the invention]

[0004] (1) In a storage box having a knob that is interlocked with a latch and whose movement is restricted when locked as in Patent Document 1, it is conceivable that a child or the like may enter the box body to play or play, causing the door to close and become locked. For this reason, from the viewpoint of safety, it is preferable to configure the delivery box so that the door can be easily unlocked and opened from the inside even in such a case. For this reason, it is desirable to realize a structure that allows the door to be easily unlocked and opened from the inside in a delivery box having a knob that is interlocked with a latch and whose movement is restricted when locked.

[0005] (2) In addition, in order to provide an easy-to-use door opening structure according to the installation location of the delivery box, it is conceivable that the delivery box manufacturer prepares at least two types of door opening operability, that is, right-opening and left-opening. However, preparing such a plurality of types of opening operability structures in advance is undesirable because it may cause erroneous orders. In addition, the number of dedicated parts for each of the plurality of types reduces the mass production efficiency, leading to increased costs, and requires the manufacturer to take care of them. In addition, when a manufacturer manufactures a plurality of types of delivery boxes, the manufacturing work is switched to manufacture different types of delivery boxes, which makes the manufacturing work less efficient. For this reason, it is desirable to realize a delivery box that allows users to easily select an opening operability that is easy to use, without the manufacturer having to prepare a plurality of types of delivery boxes in advance that cannot be changed with respect to the left or right opening operability.

[0006] An object of the present disclosure is to provide a delivery box that can solve at least problem (1) of the above problems (1) and (2). [Means for solving the problem]

[0007] A delivery box that is one aspect of the present disclosure comprises a box body capable of storing delivery items, a door body rotatably attached to the box body, and a locking block attached to the door body, wherein the box body has a top plate, two side plates, and a bottom plate, and the locking block has a locking case, a latch portion that can protrude toward a latch receiving side provided on the box body, a knob portion that interlocks with the latch portion, and a locking cam, and the locking cam has a cam protrusion that rotates when the latch portion protrudes toward the latch receiving side to regulate the returning motion of the knob portion, and two locking cam operating portions that protrude from both the upper and lower ends of the locking case. Effect of the Invention

[0008] According to one aspect of the delivery box disclosed herein, the door can be easily unlocked and opened from the inside in a configuration that has a knob portion that works in conjunction with a latch portion and restricts movement of the knob portion when locked.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] An example of an embodiment will be described in detail below with reference to the drawings. In the following, a delivery box with a post box, in which a post box having a mail slot and a storage section is integrated with the delivery box, will be described, but the present disclosure is not limited thereto. The delivery box may be configured without a post box.

[0011] 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 delivery box. In the following, the same elements are denoted by the same reference numerals in all drawings.

[0012] A delivery box 1 of an embodiment will be described with reference to Figs. 1 to 15. Fig. 1 is a perspective view of the delivery box 1. Fig. 2 is a view of the back side of the delivery box 1 with the outer door 12 removed. Fig. 3 is a perspective view showing the delivery box 1 with the outer door 12 removed. Fig. 4 is a perspective view showing the delivery box 1 of Fig. 3 with the middle door 14 and lower door 16 removed. Fig. 5 is an enlarged perspective view of part A in Fig. 3. Fig. 6 is an enlarged perspective view of part B in Fig. 3. Fig. 7 is an enlarged perspective view of part C in Fig. 3.

[0013] The delivery box 1 is for a detached house, and can receive parcels (not shown) that are parcels delivered without any person present. The delivery box 1 is used by a parcel delivery person to deposit parcels and to lock an inner door that closes a storage section that stores the parcels. For example, the delivery box 1 is placed outside a detached house near the front door. The delivery box 1 has a box body 10 in the shape of a rectangular parallelepiped having a front end opening at the front end, three inner doors arranged vertically, an upper door 13, a middle door 14, and a lower door 16, which open and close the front end opening of the box body 10, and an outer door 12 provided on the outside of each inner door. The box body has a top plate 10a, two side plates 10b on the left and right, a bottom plate 10c, and a rear plate 10d, and can store parcels. The door bodies 12a, 13a, 14a, and 16a of the outer door 12, the upper door 13, the middle door 14, and the lower door 16 are rotatably attached to the box body 10. A locking block 40, which will be described later, is attached to each of the door bodies 14a, 16a of the middle door 14 and the lower door 16.

[0014] As shown in Fig. 2, the outer door 12 has two screw holes 12b, 12c formed at both upper and lower ends of one end in the left-right direction (the left end in Fig. 2). Hinge blocks 24, 25 shown in Figs. 3 to 5 and 7 are fixed to both upper and lower ends of one end in the left-right direction of the outer door 12 via the screw holes 12b, 12c. In the following description, the side of the box body 10 where the outer door 12 is located is referred to as the front side, and the opposite side is referred to as the rear side, and the left and right are basically defined as the left and right sides when viewed from the front side of the box body 10.

[0015] In each of the hinge blocks 24, 25, a cylindrical hinge hole (not shown) is formed on the surface facing the vertical center of the box body 10. Hinge plates 26, 27 are fixed to the peripheral portion of the front end opening of the box body 10, at both vertical ends of one end in the left-right direction (the right end in FIG. 3). Each of the hinge plates 26, 27 is formed with a hinge pin that protrudes in the vertical direction from the surface opposite the vertical center of the box body 10. By inserting each hinge pin into the hinge hole, the outer door 12 is attached to the box body 10 so as to be rotatable about the hinge pin at one end in the left-right direction. Thus, in the configuration of FIG. 1 to FIG. 7, the outer door 12 is attached to the box body 10 via the hinge pin provided at the right end. As a result, the outer door 12 has a right-handed structure that can be opened to the right.

[0016] Meanwhile, the inside of the box body 10 is divided into three storage chambers 20, 21, 22 (FIG. 4) by two upper and lower partitions 28, 29. The three storage chambers 20, 21, 22 include the uppermost mail storage chamber 20 that is opened and closed by the upper door 13, the middle parcel storage chamber 21 that is opened and closed by the middle door 14, and the lowermost parcel storage chamber 22 that is opened and closed by the lower door 16. The parcel storage chambers 21, 22 are used to store parcels. A locking block 40, which is a locking device, is attached to the back side of the door bodies 16a, 14a of the lower door 16 and the middle door 14. A cylinder lock 41 of the locking block 40 is exposed on the front surface of the lower door 16 and the middle door 14. The lower door 16 and the middle door 14 can be locked and unlocked by turning the key inserted in each cylinder lock 41.

[0017] The middle door 14 and the lower door 16 are also right-handed to match the outer door 12. For example, as shown in Fig. 5, a hinge member 30 is attached by a screw to the lower right end of the periphery of the front end opening of the parcel storage compartment 22 of the box body 10. A hinge pin 30a provided on the hinge member 30 so as to protrude upward is inserted into a hole at the lower right end of the door body 16a constituting the lower door 16.

[0018] 6, a hinge member 31 is attached by a screw to the right end of the front surface of the upper partition plate 28 of the box body 10. A hinge pin 31a provided on the hinge member 31 so as to protrude downward is inserted into a hole at the upper right end of the door body 14a constituting the middle door 14.

[0019] Furthermore, a hinge pin 32 is inserted and supported in a hole at the lower right end of the door body 14a of the middle door 14 and a hole at the upper right end of the door body 16a of the lower door 16, thereby connecting the middle door 14 and the lower door 16 so that they can be opened and closed. This allows the middle door 14 and the lower door 16 to be attached to the box body 10 so as to be able to open to the right. The door bodies 14a, 16a of the middle door 14 and the lower door 16 are formed in a substantially plate-like shape from, for example, metal or resin.

[0020] 7, two hinge pins 33 protruding in the left-right direction are formed on the upper ends of the side wall surfaces on both the left and right ends of the periphery of the front end opening of the mail receiving chamber 20 of the box body 10. The two hinge pins 33 are inserted into hinge receivers (not shown) attached to the back surface of the upper door 13, whereby the upper door 13 is supported by the box body 10 so as to be capable of opening and closing in the vertical direction.

[0021] With the locking block 40 attached to the middle door 14 or the lower door 16 in an unlocked state, the delivery company places the parcel in the parcel storage room corresponding to the unlocked state, and then locks the locking block 40. At this time, with the cylinder lock 41 of the locking block 40 set to the locked position, the delivery company moves the knob part 42 exposed on the front surface of the middle door 14 or the lower door 16 in the locking direction (leftward in FIG. 3) in conjunction with the latch part of the locking block 40. As a result, the rotatable locking cam constituting the locking block 40 rotates in a predetermined direction due to the biasing force of the cam biasing member, and the rotated locking cam engages with the latch protrusion linked to the knob part. As a result, the return movement of the knob part 42 in the unlocking direction is prevented, and the locking block 40 is locked.

[0022] The cylinder lock 41 of the locking block 40 provided on the middle door 14 or the lower door 16 can be unlocked by the recipient of the parcel by inserting a key. This allows the recipient to remove the parcel from the parcel storage room. This type of parcel box 1 has a so-called "front-in, front-out structure" in which the parcel can be removed only from the front after it has been inserted from the front. The locking blocks 40 of the middle door 14 or the lower door 16 have the same structure. The configuration of the locking block 40 will be explained in detail later.

[0023] A mail slot 34 is provided at the top of the upper door 13. A flap set 35 having two sets of flaps that can rotate up and down is provided at the top of the box body 10 and behind the mail slot 34. A mail carrier opens the outer door 12 and rotates the flaps of the flap set 35 to widen the gap between the flaps, and then mails the mail into the mail slot 34. A locking block is attached to the back side of the upper door 13. A key slot of a cylinder lock 41 of the locking block is exposed on the front of the upper door 13. A mail recipient can insert a key into the key slot of the cylinder lock 41 to unlock it. This allows the recipient to open the upper door 13 and take out the mail from the mail storage chamber.

[0024] In addition, a magnet may be attached to the end of the outer door 12 opposite the mounting side of the hinge blocks 24, 25, and the magnet may be made capable of being attracted to the box body 10 made of a metal such as iron, or to a metal bracket fixed to the box body 10, thereby making it easier to keep the outer door 12 closed.

[0025] Figure 8(a) is a schematic diagram showing that the outer door 12 of a delivery box 1 opens with a right-opening action, and Figure 8(b) is a schematic diagram showing that the outer door 12 of a delivery box 1a in which the outer door 12 and each inner door of the delivery box 1 have been changed to face leftward is opened.

[0026] In the delivery box 1 shown in FIG. 1 to FIG. 7, as shown in FIG. 8(a), the outer door 12, the lower door 16, and the middle door 14 are of the right-handed type, and the outer door 12, the lower door 16, and the middle door 14 can be opened by a right-opening action. On the other hand, in the embodiment, as shown in FIG. 8(b), the outer door 12, the lower door 16, and the middle door 14 can be changed to be of the left-handed type, that is, to be opened by a left-opening action. For this reason, as shown in FIG. 2, it is preferable to form fixing parts of the hinge blocks 24, 25, which are hinge pin receiving parts, such as screw holes 12b, 12c, at positions symmetrical with respect to the center in the vertical direction on the back side position of the outer door 12. In addition, it is preferable to fix the hinge plates 26, 27, or form screw holes or holes for fixing the hinge plates, at positions symmetrical with respect to the center in the horizontal direction of the front end opening, on both left and right ends of the periphery of the front end opening of the box body 10. For example, the hinge plates 26, 27 are fixed by screws into only one of the screw holes for fixing the hinge plates on both the left and right sides in the left-right direction. Alternatively, the hinge plates 26, 27 are fixed by screws using a bolt and a nut that pass through only one of the holes for fixing the hinge plates on both the left and right sides in the left-right direction.

[0027] In addition, it is preferable to fix the hinge members 30, 31 having the hinge pins or to form screw holes or holes for fixing the hinge members at positions symmetrical with respect to the center in the left-right direction on the front surface of the box body 10. The hinge members 30, 31 are fixed by screws using only one screw hole among the screw holes for fixing the hinge members on both left and right sides. Alternatively, the hinge members 30, 31 are fixed by screws using a bolt and a nut that pass through only one hole among the holes for fixing the hinge members on both left and right sides. In addition, holes for inserting the hinge pins are formed at the same left-right positions on one side end of both the vertical end faces of the lower door 16 and the middle door 14. A locking block 40 is attached to each of the middle door 14 and the lower door 16, leaning to one side in the left-right direction from the vertical center position.

[0028] When changing the outer door 12 from a right-handed type to a left-handed type, the outer door 12 is turned upside down, and the hinge pins of each hinge plate attached to the left end of the box body 10 are inserted into the hinge holes of the hinge block attached to the outer door 12. At this time, the upper and lower hinge plates 26, 27 and the hinge blocks 24, 25 used in the right-handed type are attached to the box body 10 or the outer door 12 with their upside-down arrangement positions and upside-down orientations reversed in the left-handed type. The hinge blocks 24, 25 attached to the outer door 12 may be used for the left-handed type by turning them upside-down while attached to the door body 12a of the outer door 12. For example, the hinge plate 26 used on the upper side in FIG. 4 is attached using a plurality of screw holes 11 formed in the lower end of the left end plate portion 10e at the periphery of the front end opening of the box body 10 shown in FIG. 4.

[0029] When changing the lower door 16 and the middle door 14 from a right-hand type to a left-hand type, the upper and lower directions of the lower door 16 and the middle door 14 are reversed. Also, the hinge pin of the hinge member attached to the lower end of the left end of the box body 10 is inserted into the hole at the lower end of the lower door 16. Also, the hinge pin of the hinge member attached to the left end of the upper partition plate 28 of the box body 10 is inserted into the hole at the upper end of the middle door 14. Then, the middle door 14 and the lower door 16 are connected to each other so that they can be opened and closed by the hinge pin inserted into the left end of the upper end of the lower door 16 and the left end of the lower end of the middle door 14. At this time, the upper and lower hinge members 31, 30 used in the right-hand type are attached to the box body 10 with their upper and lower arrangement positions and upper and lower orientations reversed in the left-hand type. For example, the hinge member 31 used on the upper side in FIG. 4 is attached using a plurality of screw holes 36 formed on the lower left end of the box body 10 shown in FIG. 4. Also, the hinge member 30 used on the lower side in FIG. 4 is attached using a plurality of screw holes 37 formed on the left end of the upper partition plate 28. As a result, as shown in FIG. 8(b), the outer door 12, the lower door 16, and the middle door 14 are changed to a left-handed type. Therefore, the door bodies 12a, 16a, and 14a of the outer door 12, the lower door 16, and the middle door 14 are configured to be inverted upside down and installed on the box body 10, so that they can be adapted to left and right hand orientations. The upper door 13 may be configured to be changeable between a right-handed type and a left-handed type.

[0030] Furthermore, the locking blocks 40 attached to the middle door 14 and the lower door 16 can be installed upside down, making them compatible with the left and right sides of the middle door 14 and the lower door 16. Specifically, the locking blocks 40 have rectangular openings formed in the door bodies 14a, 16a of the middle door 14 and the lower door 16, and the front end of a locking case 43 (FIG. 9), which will be described later, is fitted into each opening and fixed. At this time, the locking case 43 may be configured to be fixed to the door bodies 14a, 16a by screw connection.

[0031] 9 is a perspective view of the locking block 40 constituting the delivery box 1 in a standby state, as seen from the front. In the locking block 40, the arrangement of the exposed parts from the front surface of the door is symmetrical with respect to the vertical center. Furthermore, the latch member 46 including the latch part 48 described below is movable in the left-right direction, and is symmetrical with respect to the vertical center of the locking block 40. Furthermore, both upper and lower ends of the locking cam 50 described below protrude from both the upper and lower ends of the locking case 43. It is preferable that the locking block 40 is configured to perform the same function even when the vertical orientation is reversed.

[0032] Furthermore, the locking block 40 has a knob portion 42 that interlocks with the latch portion 48, and is configured so that the door can be easily unlocked and opened from the inside in a configuration in which the movement of the knob portion 42 is restricted when the door is locked. The configuration and operation of the locking block 40 will be described in detail below with reference to Figures 9 and 10 to 15, assuming that the locking block 40 is attached to the lower door 16.

[0033] 10 is a perspective view of the locked state of the locking block 40 seen from the front side. The locking block 40 is attached to the back side of the door body 16a of the lower door 16, and the front surface of the locking block 40 is exposed from the front surface of the lower door through a rectangular opening formed in the door body 16a.

[0034] The locking block 40 has a locking case 43, a latch portion 48 supported on the locking case 43 so as to be movable in the left-right direction, and a knob portion 42 formed integrally with the latch portion 48 and interlocking with the latch portion 48. The latch portion 48 and the knob portion 42 are formed on a latch member 46 described later. The locking block 40 also has a cylinder lock 41 fixed to the locking case 43 and a locking cam 50 rotatably supported on the locking case 43. When the knob portion 42 is moved to the unlocking side, which is the cylinder lock 41 side, as shown in FIG. 9, the latch portion 48 retreats into the locking case 43. As a result, the latch portion 48 does not protrude toward the latch receiver 10f provided on the box body 10. Therefore, the lower door 16 is in an unlocked or standby state and can be opened.

[0035] On the other hand, when the knob portion 42 is moved to the locking side, which is the opposite side to the cylinder lock 41, as shown in Figure 10, the latch portion 48 protrudes from the locking case 43, and the latch portion 48 protrudes toward the latch receiver 10f provided on the box main body 10, locking the lower door 16.

[0036] The latch receiver 10f may be an opening edge portion at the front end of the box body 10, or may be a member different from the box body 10, such as a metal fitting fixed to this opening edge portion. The latch receiver may be a rectangular hole or may be a wall portion of the box body 10. The latch receiver may be anything that faces the latch portion 48 so as to be able to engage with it when the latch portion 48 protrudes toward the latch receiver side, and prevents the door from opening.

[0037] Both upper and lower ends of the locking cam 50 protrude from openings 44 formed at both upper and lower ends of the locking case 43. As described below, the locking cam 50 rotates when the latch portion 48 protrudes toward the latch receiver 10f side to restrict the return movement of the knob portion 42. As a result, as described below, even if a child or the like enters the box body 10 to play or play and the lower door 16 or the middle door 14 is closed and locked, the locking cam 50 can be easily touched from the inside of the box body 10, so that the door can be easily unlocked and opened by rotating the locking cam 50 to the side that does not restrict the movement of the knob portion 42.

[0038] Fig. 11 is an exploded perspective view of the locking block 40 as viewed obliquely from the rear side. Fig. 12 is an exploded perspective view of the locking block 40 as viewed obliquely from the front side, with some parts omitted. Fig. 13 is a perspective view of the locking block 40 in a standby state as viewed from the rear side with the rear case 61 forming the locking case 43 removed.

[0039] The locking case 43 is formed into a generally box-like shape by butting together a front case 60 and a rear case 61 in the front-rear direction and screwing them together with a guide plate 70 sandwiched between them. A guide wall 60a that restricts the movement of the latch member 46 in the left-right direction is formed in a portion extending from the left-right middle part to one end of the rear side surface of the front case 60. A hole 60b is formed in the other left-right end of the front case 60, and the cylinder lock 41 is held in the hole 60b, with the key insertion part of the cylinder lock 41 exposed to the front side of the front case 60.

[0040] The latch member 46 is in the shape of a block long in the left-right direction, and a knob portion 42 protrudes from the front surface. A latch portion 48 having a substantially rectangular box shape is formed at one end side of the latch member 46 in the left-right direction from the knob portion 42 (right side portion in FIG. 11), which can protrude from the locking case 43. A latch protrusion 49 formed on the rear surface of the other left-right end (left end portion in FIG. 11) of the latch member 46 engages with a rectangular hole 71 long in the left-right direction formed in a guide plate 70. This restricts the movement of the latch member 46 in the left-right direction. The latch protrusion 49 is in the shape of a substantially rectangular parallelepiped, and the lower surface is aligned with the left-right direction. Latch biasing members 80, 81 such as coil springs are housed in a recess 46a formed on the rear surface of the latch member 46. Two latch biasing members 80, 81 are combined, but only one may be provided. The latch member 46 is urged in a direction retracting into the locking case 43 by the engagement projection 72 formed on the front surface of the guide plate 70 entering the recess 46 a and being pressed against the latch urging members 80 , 81 .

[0041] A support pin 82 is fixed to the rear surface of the guide plate 70 so as to protrude rearward. The locking cam 50 is rotatably supported by the support pin 82. The locking cam 50 is formed in a substantially cross shape having a first straight portion 51 and a second straight portion 52 that are perpendicular to each other. A circular hole 54 is formed in the first straight portion 51 at a portion located on the tip side, which is one end side in the left-right direction from an intersection 53 with the second straight portion 52, and the support pin 82 is inserted into the hole 54. As a result, the locking cam 50 is rotatably supported by the locking case 43. In addition, a cam biasing member 84, which is a coil spring, is supported on the rear side of the guide plate 70 via the support pin 83 so as to be swingable about the support pin 83. Both ends of the cam biasing member 84 can be engaged with the wall portions 73, 74 protruding rearward at both upper and lower ends of the guide plate 70. Furthermore, locking protrusions 55, 56 are formed on the tip side of the first straight portion 51 of the locking cam 50 so as to protrude from both the upper and lower surfaces. Both ends of the cam biasing member 84 are engaged with the tip side surfaces of the upper and lower locking projections 55, 56. As a result, the cam biasing member 84 elastically biases the locking cam 50 so as to maintain a neutral state in which the first straight portion 51 extends in the substantially horizontal direction, that is, in the substantially left-right direction, as shown in FIG.

[0042] Furthermore, a cam protrusion 57 is formed on the front surface of the locking cam 50 at the other end of the first straight portion 51. The upper surface of the cam protrusion 57 is inclined downward toward the intersection 53 of the first straight portion 51 and the second straight portion 52. The latch protrusion 49 of the latch member 46 can engage with the upper surface of the cam protrusion 57. For example, when the latch protrusion 49 slides on the upper surface of the cam protrusion 57 to rotate the locking cam 50 so that the cam protrusion 57 descends, the latch member 46 can be moved in a direction to retract into the locking case 43.

[0043] Furthermore, both upper and lower ends of the second straight portion 52 of the locking cam 50 protrude outward from openings 44 (FIG. 9) formed at both upper and lower ends of the locking case 43. The upper and lower ends of the second straight portion 52 correspond to two locking cam operating portions protruding from both upper and lower ends of the locking case 43. Furthermore, one left-right end of the first straight portion 51 of the locking cam 50 protrudes outward from an opening 62 (FIG. 12) formed at the end of the rear case 61 of the locking case 43 on the same side as the latch portion 48.

[0044] On the other hand, the latch protrusion 49 of the latch member 46 can enter between the end face 57a of the cam protrusion 57 of the locking cam 50 on the intersecting portion 53 side and the protrusion 58 protruding from the vicinity of the intersecting portion 53 on the front surface of the locking cam 50. When the latch protrusion 49 enters between the end face 57a and the protrusion 58, the latch protrusion 49 and the end face 57a engage with each other, and the latch member 46 is prevented from returning in the direction of retreating into the locking case 43. In this state, the latch portion 48 of the latch member 46 protrudes from the locking case 43, and the rotational position of the locking cam 50 returns to the neutral state. Therefore, when the latch portion 48 protrudes toward the latch receiver 10f side, the cam protrusion 57 of the locking cam 50 rotates to restrict the return movement of the knob portion 42. In this state, the lower door 16 is locked.

[0045] A plate-shaped unlocking metal fitting 85 is fixed to the rotating part 41a protruding from the rear side of the cylinder lock 41. The tip of the unlocking metal fitting 85 can engage with the end of the first straight part 51 of the locking cam 50 on the cam protrusion 57 side. When a key is inserted into the key slot of the cylinder lock 41 and rotated in the unlocking direction, the unlocking metal fitting 85 engages with the upper end of the first straight part 51 on the cam protrusion 57 side, causing the locking cam 50 to rotate in the direction in which the cam protrusion 57 descends. This allows the latch protrusion 49 to slide on the upper surface of the cam protrusion 57, and the latch member 46 to move in the direction of retreating into the locking case 43. This unlocks the lower door 16.

[0046] The operation of the locking block 40 will be described in more detail with reference to Figs. 13 to 15. As shown in Figs. 9 and 13, in the standby state of the locking block 40, the locking cam 50 is biased by the cam biasing member 84 in the direction of the arrow α in Fig. 13 so as to return to the neutral state. Meanwhile, with the upper surface of the cam projection 57 of the locking cam 50 engaged with the lower surface of the latch projection 49 of the latch member 46, the latch projection 49 moves to the unlocked position (the left end position in Fig. 13) in the hole 71 of the guide plate 70. Therefore, the locking cam 50 is prevented from moving in the direction of the arrow α in Fig. 13. At this time, the cylinder lock 41 is in a lock preparation state, and the unlocking metal fitting 85 faces in the vertical direction and is at a position away from the cam projection 57 of the locking cam 50. In this state, the latch member 46 moves in a direction to retreat into the locking case 43, and the lower door 16 is unlocked. In this state, the delivery company opens lower door 16, places the parcel in parcel storage room 22, and then closes lower door 16.

[0047] Next, as shown in Figs. 10 and 14, the delivery man moves the knob portion 42 of the locking block 40 in a direction away from the cylinder lock 41, causing the latch portion 48 of the latch member 46 to protrude toward the latch receiver 10f. Then, the latch protrusion 49 of the latch member 46 slides on the upper surface of the cam protrusion 57 of the locking cam 50 and comes off the cam protrusion 57 in the locking direction (to the right in Fig. 14). In this state, the locking cam 50 rotates toward the neutral state due to the urging force of the cam urging member 84. Then, the latch member 46 is urged in the retracting direction by the latch urging members 80 and 81, so that the latch protrusion 49 engages with the end surface 57a of the cam protrusion 57, and the return of the latch member 46 is restricted. In addition, the state in which the latch portion 48 protrudes toward the latch receiver 10f is maintained. This allows the delivery company to lock the lower door 16 simply by moving the knob portion 42 from the front side of the lower door 16 in the left-right direction.

[0048] Next, when the recipient of the parcel receives the parcel from the parcel box 1, 1a, the key is inserted into the cylinder lock 41 of the locking block 40, and the rotating part 41a of the cylinder lock 41 is rotated in the locking direction as shown in FIG. 15. As a result, the unlocking metal fitting 85 falls in the left-right direction toward the locking cam 50 and engages with the upper end of the cam protrusion 57 side end of the first straight part 51 of the locking cam 50. Therefore, the locking cam 50 rotates to the same position as in FIG. 13, so that the latch protrusion 49 rides on the upper surface of the cam protrusion 57 and moves to the unlocking position (the left end position in FIG. 15) in the hole 71 of the guide plate 70. As a result, the latch part 48 of the latch member 46 retreats from the latch receiver 10f side into the locking case 43. FIG. 15 shows the state immediately before the latch part 48 retreats into the locking case 43.

[0049] This unlocks the lower door 16, allowing the recipient to take out the parcel from the parcel storage compartment 22. After receiving the parcel, the recipient inserts a key into the cylinder lock 41 and rotates it to the lock preparation position shown in Fig. 9 in order to prepare the parcel box 1, 1a for receiving the next parcel. This returns the locking block 40 to the standby state shown in Fig. 9.

[0050] Furthermore, in the locked state of FIG. 10, both upper and lower ends of the second straight portion 52 protrude from both upper and lower ends of the locking case 43. Therefore, even if a child or the like enters the box body 10 for playing or mischief and the lower door 16 is closed and locked, the child or the like can easily touch the locking cam 50 from inside the box body 10. Then, by rotating the locking cam 50 in the direction of the arrow β in FIG. 14 from the state of FIG. 14, the latch portion 48 of the latch member 46 can be retreated into the locking case 43 as shown in FIG. 9 and FIG. 13, and the lower door 16 can be unlocked. In this case, the locking cam 50 rotates to the side that does not restrict the return movement of the knob portion 42. Therefore, the door can be easily unlocked from the inside of the box body 10 and opened.

[0051] Although the locking block 40 of the lower door 16 has been described above, the locking block 40 of the middle door 14 is similar. This allows the lower door 16 and the middle door 14 to be locked with a locking structure that does not use a power source such as a 100V AC power source or a battery. In addition, the locking block 40 is configured to be able to be installed upside down, so that it can accommodate the lower door 16 and the middle door 14 being configured to have different left and right openings. This allows the manufacturer of the delivery box 1 to easily select the opening direction that is easiest for the user to use, without having to prepare in advance multiple types of delivery boxes that cannot be changed with respect to the left and right opening direction.

[0052] Unlike the embodiment shown in Figs. 1 to 15 above, the inside of the box body may be divided into two chambers, a mail-in storage chamber at the top and a luggage storage chamber below the mail-in storage chamber, and the front end opening of the mail-in storage chamber may be closed by a right-opening upper door so as to be openable and closable, and the front end opening of the luggage storage chamber may be closed by a right-opening lower door so as to be openable and closable. For this reason, the upper door and the lower door are attached to the box body in a right-opening type. A dial lock is attached to the left end of the upper door, and a mail-in slot is formed from the middle to the right end. The locking block 40 of the above embodiment is attached to the left end of the lower door. In this configuration, the outer door is also attached to the box body in a right-opening type. In this case, the outer door, the upper door, and the lower door can be inverted upside down and attached to the box body in a left-opening type.

[0053] Fig. 16(a) is a schematic diagram of a delivery box 2 according to another embodiment, in which the outer door 12 and the lower door 17 are opened in a right-opening motion and the rear door 18 is opened in a left-opening motion, as viewed from the front side. Fig. 16(b) is a schematic diagram of the same state as Fig. 16(a), as viewed from the rear side. Fig. 16(c) is a schematic diagram of the front portion of the lower door used in Figs. 16(a) and 16(b), and the link block 90, as viewed from the front side.

[0054] As shown in FIG. 16(a), in the configuration of this example, the inside of the box body 10 is divided into two chambers: a mailed item storage chamber 20 at the top and a parcel storage chamber 23 below it. The front end opening of the mailed item storage chamber 20 is closed openably by an upward-opening upper door 13 similar to the configuration of FIGS. 1 to 15, and the front end opening of the parcel storage chamber 23 is closed openably by a right-opening lower door 17. A locking block 40 is attached to the left end of the lower door 17, similar to the configuration of FIGS. 1 to 15. In this configuration, the outer door 12 is also attached to the box body 10 as a right-opening door.

[0055] In the configuration of this example, as shown in Fig. 16(b), the rear end openings of the mail item storage chamber 20 and the parcel storage chamber 23 of the box body 10 are closed openably and closably by a common rear door 18 that opens to the left when viewed from the rear. For this reason, the rear door 18 is rotatably attached to the box body 10 on the opposite side to the door body 12a of the outer door 12. A cylinder lock 41 is attached to the end of the right side (left side when viewed from the rear) of the rear door 18.

[0056] In this case, as shown in FIG. 16(c), the link block 90 is attached to the wall surface at the left end of the inside of the box body 10 along the front-rear direction so as to be able to face one end of the locking cam 50 (FIG. 13) of the locking block 40 in the left-right direction. The link block 90 includes a link portion extending in the front-rear direction. The link portion is engageable with the locking cam 50 of the locking block 40 and a rotating portion of the rear cylinder lock 110, which is a locking portion attached to the rear door 18. The locking cam 50 is linked to the link portion in a state in which the link portion and the locking cam 50 are engaged with each other. As a result, as described later, the locking block 40 of the lower door 17 can also be unlocked by unlocking the rear cylinder lock 110 of the rear door 18. Such a delivery box 1 has a structure in which a parcel can be put in from the front side and then taken out from the rear side, which is a so-called "front-in, rear-out structure."

[0057] Fig. 17(a) is a schematic diagram of the delivery box 2a in Fig. 16 in which the outer door 12 and the lower door 17 are changed to open to the left, viewed from the front. Fig. 17(b) is a schematic diagram of the same configuration as Fig. 17(a), viewed from the rear, with the rear door 18 opened to the right. Fig. 17(c) is a schematic diagram of the front portion of the lower door 17 used in Figs. 17(a) and (b) and the link block 90, viewed from the front.

[0058] In the configuration shown in FIG. 16, as shown in FIG. 17(a), the outer door 12 and the lower door 17 can be inverted upside down and attached to the box body 10 as a left-opening type. Also, as shown in FIG. 17(b), the rear door 18 can be inverted upside down and attached to the box body 10 as a right-opening type when viewed from the rear side. In this case, as shown in FIG. 17(c), the link block 90 used in the configuration of FIG. 16 is attached to the wall surface at the right end of the inside of the box body 10 along the front-rear direction so as to be opposed to one end in the left-right direction of the locking cam 50 of the locking block 40. As a result, even in a configuration having the rear door 18, the outer door 12 and the lower door 17 can be changed between the right-hand side and the left-hand side, and the rear door 18 can be changed between the left-hand side and the right-hand side when viewed from the rear side.

[0059] Furthermore, the locking block 40 attached to the lower door 17 can be installed upside down, similar to the configuration in Figures 1 to 15, so that it can be adapted to accommodate left and right doors. The link block 90 can also be installed upside down, so that it can be adapted to accommodate left and right doors.

[0060] The front and rear locking interlocking mechanism 100 including the link block 90 will be described below with reference to Figs. 18 to 23. Fig. 18 is a diagram showing the locking block 40 in the standby state and the rear cylinder lock 110 in the locked state in the delivery box 2, and is a perspective view of the front and rear locking interlocking mechanism 100 taken out and seen from the front. Fig. 19 is a perspective view of the front and rear locking interlocking mechanism 100 taken out and seen from the rear. Fig. 20 is a perspective view of the front and rear locking interlocking mechanism 100 taken out and with the link case 91 omitted.

[0061] As shown in Fig. 18, the front and rear locking interlocking mechanism 100 includes a locking block 40, a link block 90, and a rear cylinder lock 110. In this example, the tip portion (the right end portion in Fig. 19), which is one end portion in the left-right direction of the first straight portion 51 of the locking cam 50 constituting the locking block 40, corresponds to the link protrusion.

[0062] 18 and 19, a portion of the plate member that forms the box body 10 that forms the front end opening is bent into a mountain shape with a generally rectangular cross section to form a latch receiver 100g. The link block 90 has a flat shape that is long in the front-rear direction and has a box-shaped link case 91 that is open at the end close to the inner surface of the box body 10, and a link part 92 (FIG. 20) that is arranged inside the link case 91.

[0063] A rear cylinder lock 110 is attached to one left-right end of the rear door 18. The rear cylinder lock 110 has a rotating part 110a protruding forward, to which a rotating metal fitting 111 having a crank-shaped cross section is fixed, and a locking pin 112 protruding forward is fixed to the tip of the rotating metal fitting 111.

[0064] As shown in FIG. 20, the link portion 92 has a rear locking member 94, which is a metal fitting, fixed to the rear end of a rod 93 that is long in the front-rear direction, and the tip of the rear locking member 94 can engage with a locking pin 112. A front locking member 95 having a substantially elliptical cross section is fixed to the front end of the rod 93. The rear locking member 94 and the front locking member 95 can protrude through openings 98, 99 to the outside of the link case 91, respectively. The tip of the front locking member 95 can engage with the underside of the tip of the first straight portion 51 of the locking cam 50. A link biasing member 97, which is a coil spring, is provided to the link portion 92, and one end of the link biasing member 97 engages with the inner surface of the link case 91 and the other end is locked to the front locking member 95. As a result, the link biasing member 97 biases the link portion 92 so that the rear locking member 94 and the locking pin 112 move away from each other and the front locking member 95 and the tip of the first straight portion 51 move away from each other, as shown in Figures 19 and 20.

[0065] In the state shown in Fig. 20, as shown in Fig. 18, the tip of the rotating metal fitting 111 of the rear cylinder lock 41 faces the front surface of the latch receiver 100h formed at the rear end of the box body 10. Therefore, the rear door 18 is locked. In Figs. 18 and 19, the locking block 40 is in a standby state, similar to the configurations in Figs. 9 and 13. Therefore, when the knob portion 42 is moved in the locking direction (leftward in Fig. 18), the latch portion 48 (Fig. 10) protrudes toward the latch receiver 100g, entering the locked state.

[0066] Fig. 21 is a rear view corresponding to Fig. 19, showing the state in which the locking block 40 has been locked and then the unlocking operation has been performed to unlock the delivery box 2 with the rear cylinder lock 110. Fig. 22 is a rear view of Fig. 21 with the box body 10 omitted. Fig. 23 is a rear view of Fig. 22 with the link case 91 omitted.

[0067] As shown in Figs. 21 to 23, after the locking block 40 is locked, when the recipient of the parcel receives the parcel, the recipient inserts a key into the rear cylinder lock 110 and rotates it to the unlock side. As a result, the tip of the rotating metal fitting 111 of the rear cylinder lock 110 does not face the front surface of the latch receiver 100h at the rear end of the box body 10. Therefore, the rear door 18 is unlocked. In this state, the recipient can open the rear door 18 and take out the parcel from the rear side of the box body 10.

[0068] On the other hand, in this state, the locking pin 112 fixed to the tip of the rotating metal fitting 111 engages with the tip of the rear locking member 94, rotating the link portion 92 in the direction of the arrow γ in FIG. 23. Therefore, the front locking member 95 also rotates in the same direction as the rotation direction of the link portion 92. At this time, the front locking member 95 engages with the lower surface of the tip of the first straight portion 51 of the locking cam 50, rotating the locking cam 50 to the state shown in FIG. 13 described above. Therefore, the latch member 46 moves in the unlocking direction so that the latch protrusion 49 rides on the upper surface of the cam protrusion 57 of the locking cam 50, and the latch portion 48 of the latch member 46 retreats into the locking case 43. As a result, the lower door 17 is also unlocked, and the locking block 40 is in a standby state. Therefore, the locking block 40 of the lower door 17 can also be unlocked and in a standby state by unlocking the rear cylinder lock 41 of the rear door 18. This eliminates the need for the recipient to open the rear door 18, go to the front of the delivery box 1, and use a key to turn the cylinder lock 41 of the lower door 17 in the unlocking direction to put the box into a standby state, which is a cumbersome operation.

[0069] Furthermore, the front / rear locking interlocking mechanism 100 can be used for both the left and right, and the link block 90 removably fixes the link case 91 to the box body 10 by screwing. For example, as shown in Figures 20 and 23, the link case 91 can be fixed to the inner surface of the box body 10 inside the link case 91 and screwed to the top of a mounting bracket 114 that protrudes inward in the left-right direction in a mountain shape. At this time, a bracket having the same shape as the mounting bracket 114 in Figures 20 and 23 may be fixed in advance to the wall portions on both the left and right ends on the inner surface of the box body 10.

[0070] Fig. 24(a) is a schematic diagram of a delivery box 2 according to another embodiment, seen from the front, before and after changing the lower door 17 from a right-handed (right-opening) to a left-handed (left-opening). Fig. 24(b) is a schematic diagram of a delivery box 2 according to another embodiment, seen from the rear, before and after changing the rear door 18 from a left-handed (left-opening) to a right-handed (right-opening).

[0071] As shown in FIG. 24(a), in the configuration of this example, the locking block 40 is located at the vertical center of the lower door 17, so that the lower door 17 can be turned upside down and easily changed to the left or right side. Also, as shown in FIG. 23, the rear cylinder lock 41 and the locking block 40 are slightly offset in the vertical direction. Therefore, when changing the rear door 18 from a left-opening type to a right-opening type as viewed from the rear side, the rear cylinder lock 110 may be offset in the vertical direction to the opposite side from the vertical center of the rear door 18. This vertical offset is actually slight, so it is considered that it does not interfere with use.

[0072] According to the configuration of this example, even if the delivery box 2 has a rear door 18, the manufacturer of the delivery box 2 does not have to prepare multiple types of delivery boxes in which the door cannot be changed in terms of which way it opens to the left or right, and the user can easily select the opening direction that is easiest for the user to use.

[0073] Furthermore, by preparing two types of box body 10, one with an opening only at the front end and one with openings at the front and rear ends, it becomes easy to realize four types of delivery boxes 1, one with a front-in, front-out structure on the left and right sides and one with a front-in, rear-out structure on the left and right sides, using many shared parts with a common structure for outer door 12, lower door 17, upper door 13, locking block 40, etc. In this example, the other configurations and functions are the same as those in Figs. 1 to 15.

[0074] In the configurations of Figs. 16 to 24, a dial lock may be used instead of cylinder lock 110, and a rotating metal fitting may be fixed to the end of the rotating part of the dial lock on the box body 10 side. [Explanation of symbols]
