Japanese Unexamined Patent Publication No. 2006-174880

In recent years, the products delivered to the mailbox have diversified, and it has become possible to post thick mail. As a result, it is desirable to increase the width of the mailing port, but if the width of the mailing port is increased, it becomes easier for a person to pull out the mailed item by hand inserted into the mailing port from the outside. According to the configuration described in Patent Document 1, even in this case, it is difficult to pull out the posted object from the inside and the crime prevention property can be enhanced. On the other hand, if the length of each small flap in the width direction of the mailing port extends over the entire width of the mailing port, the small flap must be returned in the closing direction unless the urging force is increased. May get worse.

An object of the present disclosure is to provide a mailbox that can easily reduce the force of returning the flap to the closing direction of the mailing slot and can improve the crime prevention property.

The mailbox of the present disclosure is a mailbox including a post body for accommodating items posted from a mailbox and a flap set rotatably supported by the post body to open and close the mailbox. It is formed by a first flap and a second flap arranged in two rows facing each other, and the first flap is rotatable about a first axis arranged on one side in the width direction of a mailing port and is a second. The flap is rotatable about a second axis arranged on the other side in the width direction of the mailbox, and at least one of the first flap and the second flap has a plurality of movable pieces and is a mailbox. The width of each of the first flap and the second flap is within the inner range of the mailbox with the mailbox, the first flap and the second flap viewed in the mailbox direction. The length in the direction is the mailbox, which is smaller than the width of the mailing slot.

According to the mailbox according to the present disclosure, when a person puts his / her hand in the mailing slot and tries to pull out the mailed item in the post body from the outside, the movable piece different from the movable piece of the flap pushed in by hand is closed. Since it is left as it is, the mailed object hits the closed movable piece and is prevented from being taken out from the mailing port. Further, within the inner range of the mailing port when each flap is viewed in the mailing direction, the length of each flap in the width direction of the mailing port is smaller than the width of the mailing port. As a result, it becomes easy to reduce the urging force for returning the flap to the closing direction, and it is possible to improve the crime prevention property.

In the closed state of the first front door 14 and the second front door 16, the back side B portion of the upper end portion of the first front door 14 is covered with the lower end portion of the second front door 16. A dial lock (not shown) is installed at the upper end of the first front door 14 and is covered by the second front door 16 when the second front door 16 is closed. In the locked state of the dial lock, a rotatable protrusion provided on the back side B end of the dial lock engages with the lower end of the front side F end of the upper unit 20 described later. As a result, the first front door 14 is prohibited from rotating to the front side F. When the recipient of the mailing item 100 takes out the mailing item 100 from the mailbox 12, the dial lock is operated to unlock the dial lock with the second front door 16 raised and the dial lock exposed. In this state, the engagement between the protrusion of the dial lock and the upper unit 20 is released. In this state, the recipient rotates the first front door 14 toward the front side F and takes out the items to be posted from the accommodating portion 19a.

The lid door 18 is rotatably attached to the post body 19 at the upper end of the back side B end around an axis (not shown) along the left-right direction. As shown in FIG. 3, in a state of being rotated so as to lift the lid door 18, the upper unit 20 described later having the mailing port 22 and the flap assembly 32 is exposed. The upper unit 20 is attached to the upper part of the post body 19 inside the lid door 18 so as to close the opening at the upper part of the post body 19.

FIG. 4 is a perspective view showing the upper unit 20 taken out from the mailbox 12. FIG. 5 is a view of the upper unit 20 of FIG. 4 as viewed from above. FIG. 6 is an exploded perspective view of the upper unit 20. FIG. 7 is a perspective view seen from the lower side, omitting the upper frame 21 and the lower frame 26 from FIG.

The upper unit 20 includes an upper frame 21, a lower frame 26 assembled on the lower side of the upper frame 21, a first axis 40, a second axis 42, and a flap assembly 32. The upper frame 21 and the lower frame 26 are each formed in a substantially rectangular frame shape as a whole. The upper frame 21 is formed with a rectangular mailing port 22 that penetrates in the vertical direction and is long in the horizontal direction. The mailing port 22 has a size capable of passing through a large rectangular parallelepiped mailing object having a length of 24 cm, a thickness of 7 cm, and a width of about 17 cm, for example. The upper frame 21 is fixed to the post body 19. Holes 23 for locking the first urging member 44, which will be described later, are formed at a plurality of positions in the longitudinal direction (left-right direction) of one end in the width direction (F end on the front side) of the upper frame 21. Grooves 24 for locking the second urging member 46, which will be described later, are formed at a plurality of positions in the longitudinal direction of the lower end surface of the other end in the width direction (B end on the back side) of the upper frame 21. Support holes 25a and 25b are formed at positions separated on both sides in the width direction of both ends of the upper frame 21 in the longitudinal direction to penetrate and support the first shaft 40 and the second shaft 42, which will be described later. A rectangular frame-shaped recess 21a is formed on the lower side surface of the upper frame 21.

Grooves 27 for locking the second urging member 46 are formed at a plurality of positions in the longitudinal direction of the upper end surface of the other end in the width direction (back side B end) of the lower frame 26. With the lower frame 26 fitted in the recess 21a of the upper frame 21, the lower frame 26 is screwed to the upper frame 21.

Further, the flap set 32 is supported on the upper frame 21. The flap set 32 is formed by the first flap 33 and the second flap 35 arranged in two rows facing each other. Specifically, both ends of the first shaft 40 are penetrated and supported by the two support holes 25a on the front side F of the upper frame 21. A plurality of first movable pieces 34 are rotatably supported side by side in the left-right direction at a plurality of positions in the longitudinal direction of the first axis 40. The plurality of first movable pieces 34 form the first flap 33. The first movable piece 34 has a substantially triangular plate shape, and its length in the left-right direction decreases from the wide portion 34a of the base end portion toward the tip end portion.

The first shaft 40 penetrates through both ends of the base end of the first movable piece 34 in the left-right direction. A first urging member 44, which is a coil spring, is supported below the left-right intermediate portion of the base end portion of the first movable piece 34 at a plurality of positions of the first shaft 40. One end of the first urging member 44 is locked in the hole 23 of the upper frame 21, and the other end of the first urging member 44 is pressed against the lower surface of the first movable piece 34. The first movable piece 34 extends in the width direction of the mailing port 22 under the mailing port 22 of the upper frame 21 in a state where no external force is applied to the first movable piece 34, and the mailing port 22 is extended together with the second movable piece 36 described later. Can be opened and closed. As a result, the first movable piece 34 is urged in the closing direction of the mailing port 22. That is, the first movable piece 34 is urged by the first urging member 44 so as to keep the mailing port 22 closed without applying an external force.

On the other hand, both ends of the second shaft 42 penetrate and are supported in the two support holes 25b on the back side B of the upper frame 21. A plurality of second movable pieces 36 are rotatably supported side by side in the left-right direction at a plurality of positions in the longitudinal direction of the second axis 42. The plurality of second movable pieces 36 form the second flap 35. The shape of the second movable piece 36 is the same as that of the first movable piece 34, and the direction from the base end to the tip is opposite to that of the first movable piece 34. The second shaft 42 penetrates through both ends of the base end of the second movable piece 36 in the left-right direction. A second urging member 46, which is a coil spring, is supported below the left-right intermediate portion of the base end portion of the second movable piece 36 at a plurality of positions of the second shaft 42. One end of the second urging member 46 is locked to the groove 24 of the upper frame 21 and the groove 27 of the lower frame 26 so as to be sandwiched from both sides in the vertical direction. The other end of the second urging member 46 is pressed against the lower surface of the second movable piece 36. The second movable piece 36 extends in the width direction of the mailing port 22 under the mailing port 22 of the upper frame 21 in a state where no external force is applied to the second movable piece 36, and opens and closes the mailing port 22 together with the first movable piece 34. Close as much as possible. As a result, the second movable piece 36 is urged in the closing direction of the mailing port 22. In this state, the second movable piece 36 is inserted into the triangular valley-shaped space formed between the two adjacent first movable pieces 34. As a result, the first movable piece 34 and the second movable piece 36 are alternately arranged in the longitudinal direction of the mailing port 22 on the lower side of the mailing port 22 which is the inside of the post body 19 from the mailing port 22, and the external force is applied. In the state where it is not added, it becomes a flat plate along the substantially horizontal direction as a whole.

Further, the plurality of first movable pieces 34 are arranged in the left-right direction so that the wide portion 34a at the base end portion is continuous in the left-right direction. The plurality of second movable pieces 36 are also arranged in the left-right direction so that the wide portion 36a at the base end portion is continuous in the left-right direction. As a result, the flap assembly 32 is rotatably supported by the post body 19 and opens and closes the mailing port 22. Further, the first flap 33 and the second flap 35 are arranged in two rows facing each other in the width direction of the mailing port 22. Further, the first flap 33 is rotatable about the first axis 40 arranged on one side in the width direction of the mailing port 22, and the second flap 35 is arranged on the other side in the width direction of the mailing port 22. It is rotatable around the second axis 42. Further, as shown in FIG. 5, each of the first flap 33 and the second flap 35 is within the inner range of the mailing port 22 with the mailing port 22, the first flap 33 and the second flap 35 viewed in the mailing direction. The lengths L1 and L2 in the width direction of the mailing port 22 (vertical direction in FIG. 5) are smaller than the width W of the mailing port 22. Further, the first axis 40 and the second axis 42 are arranged below the mailing port 22 and at positions that do not overlap with the inner range of the mailing port 22 in the mailing direction.

Further, the plurality of first movable pieces 34 and the plurality of second movable pieces 36 can rotate independently. Further, each of the plurality of first movable pieces 34 and the plurality of second movable pieces 36 has a shape in which the length of the mailing port 22 in the longitudinal direction (left-right direction in FIG. 5) becomes smaller toward the tip.

FIG. 8 is a perspective view showing the movements of the plurality of movable pieces 34, 36 of the flaps 33, 35 when the mailing object 100 is put into the mailing port 22 (FIG. 3) in the embodiment. As shown in FIG. 8, when the flap set 32 is pushed by the mailing material 100 from above when the mailing material 100 is posted to the mailing port 22 by the delivery person, the movable pieces 34, 36 are the first shaft 40 or the second. It rotates around the shaft 42 toward the accommodating portion 19a. Then, from the state of FIG. 8, the items to be posted 100 can be dropped onto the accommodating portion 19a in a state where the movable pieces 34 and 36 are further rotated toward the accommodating portion 19a. After the items to be posted 100 have fallen, the movable pieces 34 and 36 are rotated in the closing direction by the urging members 44 and 46 (FIG. 7) to be in a substantially horizontal state.

On the other hand, when a person who intends to steal the mailing object 100 tries to pull out the mailing object 100 from the accommodating portion 19a by putting his / her hand in the mailing port 22 from the outside, the movable pieces of the flaps 33 and 35 pushed in by hand. Since the movable pieces 34 and 36 different from those of 34 and 36 remain closed, the items 100 larger than the hand hit the closed movable pieces 34 and 36 and take out the items 100 from the mailing port 22. Is prevented. Further, within the inner range of the mailing port 22 with the flaps 33 and 35 viewed in the mailing direction, the lengths L1 and L2 of the flaps 33 and 35 with respect to the width direction of the mailing port 22 are the width of the mailing port 22. It is smaller than W. As a result, it becomes easy to reduce the urging force for returning the flaps 33 and 35 to the closing direction, and it is possible to improve the crime prevention property.

Further, the first axis 40 and the second axis 42 are arranged below the mailing port 22 and at positions that do not overlap with the inner range of the mailing port 22 in the mailing direction. As a result, the size of the portion of the mailing port 22 through which the mailed object 100 can pass is not reduced by the presence of the first axis 40 and the second axis 42. Therefore, it becomes easy to increase the size of the items to be posted 100 that can be posted to the mailbox 12.

Further, since the plurality of first movable pieces 34 and the plurality of second movable pieces 36 can rotate independently, each of the first flap 33 and the second flap 35 when the items to be posted 100 are pulled out. A movable piece that is opened downward by pushing it in by hand and a movable piece that is closed are mixed. As a result, it becomes more difficult to pull out the mailed object 100 from the accommodating portion 19a, so that the crime prevention property can be further improved.

Further, each of the plurality of first movable pieces 34 and the plurality of second movable pieces 36 has a shape in which the lengths L1 and L2 in the longitudinal direction of the mailing port 22 become smaller toward the tip. As a result, the area of the movable pieces 34 and 36 seen in the mailing direction of the mailing port 22 becomes smaller, so that it becomes more difficult to pull out the mailed object 100 in the accommodating portion 19a from the mailing port 22.

In the above, the case where the coil springs are used as the urging members 44 and 46 has been described, but the urging member is not limited to this, and the urging member urges the movable piece of the flap in the closing direction of the mailing port 22. It may be an elastic member such as a leaf spring or rubber.

FIG. 9 is a perspective view of the mailbox 12a of another embodiment of the embodiment, in which the lid door 18 is opened, as viewed from above. FIG. 10 is a schematic diagram of the switching mechanism 50. In the configuration of this example, the first flap 61 forming the flap set 60 is rotatable about the first axis 40 (FIG. 6) arranged on one side (front side F) in the width direction of the mailing port 22. It is formed by a plurality of first movable pieces 62. The plurality of first movable pieces 62 have a substantially rectangular plate shape and can rotate independently. The plurality of first movable pieces 62 are urged in the closing direction of the mailing port 22 by a first urging member (not shown) such as a coil spring. On the other hand, the second flap 63 forming the flap set 60 is rotatable about a second shaft 42 (FIG. 10) arranged on the other side (back side B) in the width direction of the mailing port 22. The second flap 63 has a substantially rectangular plate shape long in the longitudinal direction of the mailing port 22, and faces the plurality of first movable pieces 62 in the width direction of the mailing port 22. The second flap 63 is urged in the closing direction of the mailing port 22 by a second urging member (not shown) such as a coil spring. As a result, the first flap 61 and the second flap 63 are arranged in two rows facing each other in the width direction of the mailing port 22.

Further, the upper frame 64 is supported by a switching mechanism 50 for switching between permission and prohibition of rotation of the second flap 63. For example, in the second flap 63, one end in the width direction (back side B end) is fixed to the second shaft 42. As shown in FIG. 10, the switching mechanism 50 is formed on, for example, two gears 51 fixed to both ends of the second shaft 42, a claw portion 52 engaged with the gear 51 from the outer peripheral side, and a claw portion 52. A shaft portion 54 having one end rotatably connected to the tip end portion of the arm portion 53 is included. Although FIG. 10 shows the switching mechanism 50 on one end side of the second shaft 42, the same applies to the switching mechanism on the other end side of the second shaft 42.

The two shaft portions 54 forming the switching mechanism 50 are arranged along the direction parallel to the width direction of the mailing port 22 on the lower side outside the longitudinal direction from both ends in the longitudinal direction of the mailing port 22 of the upper frame 64. .. Each shaft portion 54 is supported by the upper frame 64 so as to be movable only in the longitudinal direction. The shaft portion 54 is urged by the shaft urging member 55 on one side (front side F) in the width direction of the mailing port 22. Then, in a state where no external force is applied to the shaft portion 54, the claw portion 52 rotates about the tip portion of the arm portion 53 in response to the urging force of the shaft urging member 55 and engages with the gear 51. Therefore, the rotation of the second flap 63 fixed to the second shaft 42 is prohibited. An operation portion 56 is formed on the upper side of the end portion (front side F end portion) of the shaft portion 54 opposite to the claw portion 52. The operation unit 56 is formed in the upper frame 21 and projects upward from the opening 57 which is long in the width direction of the mailing port 22. As a result, the two operation units 56 arranged apart from each other by a predetermined distance or more are arranged at the two positions outside the longitudinal direction from both ends of the mailing port 22 in the longitudinal direction. The distance between the two operating units 56 is a distance that a person cannot operate at the same time without using both hands, for example, a predetermined distance is 20 cm. As a result, the switching mechanism 50 retracts the claw portion 52 from each gear 51 and permits the rotation of the second flap 63 only when the two operating portions 56 are operated at the same time. Further, the length of each of the flaps 61 and 63 in the width direction of the mailing port 22 is smaller than the width of the mailing port 22 within the inner range of the mailing port 22 when each flap 63 is viewed in the mailing direction.

According to the configuration of this example, when the mailbox is put in the mailbox 12a, the delivery person operates the two operation units 56 at the same time with both hands while the mailbox is placed on the flap set 60. The rotation of the second flap 63 is permitted, and the flaps 61 and 63 are rotated inside the mailbox 12a by the weight of the mailbox, and the mailbox is dropped into the storage portion 19a of the mailbox 12a. On the other hand, when a person who intends to steal the mailed object puts his / her hand in the mailing port 22 from the outside and tries to pull out the mailed object from the accommodating portion 19a, the two operating units 56 are simultaneously operated with both hands to perform the second operation. Since the flap 63 must be allowed to rotate, the mailing port 22 cannot even be touched. This makes it possible to improve the crime prevention property. In this example, other configurations and operations are the same as those of FIGS. 1 to 8.

In this example, the case where the switching mechanism 50 is mechanically switched by the operation of the two operation units 56 has been described, but the two operation units are set as on / off switches that are normally turned off, and the two operation units are turned on at the same time. The operation of the switching mechanism may be controlled by the control unit so that the switching mechanism allows the rotation of the second shaft 42 only when it is operated. In this case, for example, a motor is used as a power for switching the switching mechanism.

Further, even if the switching mechanism is allowed to rotate only when either two operation units are operated at the same time or a force is applied to the second flap 63 from above. good. For example, a load sensor for detecting a load is provided on the lower side of the second flap 63, and when the load sensor detects that a load is applied from the upper side of the second flap 63, the switching mechanism is seconded by the control unit. The rotation of the shaft 42 may be permitted. As a result, when the delivery person delivers the mailed item, when the mailed item is placed on the second flap 63 and the second flap 63 is pushed downward, the load sensor detects the load on the lower side and the second flap is used. Since the rotation of the 2 flaps 63 is permitted, it is possible to put the items to be posted in the mailbox without operating the two operation units.

Further, in the configurations of FIGS. 9 and 10, rotation permission and rotation prohibition of both the first flap 61 and the second flap 63 or only the first flap 61 may be switched by the switching mechanism. Further, in the configurations of FIGS. 1 to 8, a switching mechanism for switching between permission and prohibition of rotation of at least one of the first flap and the second flap is provided, and the switching mechanisms are separated from each other by a predetermined distance or more. When two arranged operation units are operated at the same time, the rotation of at least one flap may be permitted.

Further, in each of the above examples, the first flap and the second flap may be arranged at different positions in the vertical direction, and may be arranged so that a part, for example, a tip portion thereof overlaps in the mailing direction. In this case, the first flap and the second flap face each other in the posting direction.

Further, in each of the above examples, the case where the first axis and the second axis supporting the flap assembly are supported by the upper frame fixed to the post body has been described, but the first axis and the second axis are attached to the post body. It may be directly supported. At this time, a mailing port may be formed directly on the upper part of the post body.
