JP 2009-45328 A

In Patent Document 1, the support shaft and the throwing door are always urged to the closed position by the spring member. For this reason, when pulling out the throwing object and the hand inserted into the throwing port, the support shaft moves in the direction opposite to the biasing direction of the spring member, so that the throwing object and the hand can be pulled out.
However, there has been a problem that until the throwing object and the hand are completely pulled out from the throwing opening, the spring member continues to apply force in the direction in which the throwing door bites into the throwing object and the hand. For this reason, when pulling out a throwing object or hand, the biasing force applied by the spring member becomes resistance, and a force to pull out the throwing object or hand is required to some extent, and it can not be easily pulled out when the pulling force is weak such as a child. There was a problem.

  An object of the present invention is to provide a posting port apparatus that can easily pull out a throwing item or a hand when a throwing item or a hand is inserted into the posting port.

A loading port apparatus of the present invention includes a loading port member in which a loading port is opened, a loading door that closes the loading port, a support shaft that pivotally supports the posting door, and the support shaft. A guide member having a guide groove that is movably guided in a direction crossing the axial direction of the support shaft, and a spring member attached to the support shaft and biasing the posting door in a direction to close the posting port; When the support shaft is in a closed position that is one end side of the guide groove, the posting port can be closed by the posting door, and the support shaft can be closed from the one end side to the other. When moved in the direction of the open position, which is the end side, a gap is secured between the throwing door and the throwing opening, and the support shaft is closed to the open position side of the guide groove from the closed position. It is formed holder for holding so as not to move to the side And wherein the door.

According to the present invention, the support shaft is provided so as to be movable in the direction intersecting the axial direction of the support shaft from the closed position to the open position of the loading door by the guide member, and the support shaft moves in the direction of the open position. In this case, a gap is secured between the posting door and the posting port. For this reason, when pulling out the throwing object and the hand sandwiched between the throwing door and the throwing opening from the posting side (outside the throwing opening member), the support shaft and the throwing door are moved toward the open position by the guide member. be able to. For this reason, when pulling out the throwing object and hand from the throwing side (outside) of the throwing port, the throwing door does not bite into the throwing object or the hand, and it can be easily pulled out without damaging the throwing object or the hand.
Further, a spring member for urging the posting door is attached to the support shaft, and by urging the posting door against the support shaft, the support shaft itself is urged toward the closed position as in the patent document. There is no need to do. Thus, since the support shaft itself is not biased to the closed position by the spring, a large force is not required when the support shaft is moved from the closed position toward the open position. For this reason, a spindle and a throwing door can be moved easily, and a throwing thing and a hand can be easily pulled out with a small force from a throwing mouth. Therefore, even a person with weak power, such as a child, can easily pull out the throwing thing and hand.
The gap may be set so as to secure a gap having a dimension that allows the throwing object and the hand to be easily pulled out in consideration of the thickness of the throwing object and the hand. Further, the posting door is of an inner opening type that opens and closes the posting port from the inside of the posting port member. Here, the posting port member is attached to the entrance door or attached to a post or the like fixed to an outdoor gate pillar or the like. Therefore, the outside of the posting port member is the outdoor side of the entrance door or the outside of the post, and is the posting side on which the post is thrown into the posting port. In addition, the inside of the posting port member is the indoor side of the entrance door or the internal side of the post. Further, the axial direction of the support shaft is a direction orthogonal to the penetrating direction of the posting port (the direction from the outside to the inside of the posting port member). Therefore, the direction intersecting the axial direction of the support shaft is, for example, a horizontal type (a support shaft is horizontal) provided at the entrance door or post, for example, in the vertical direction or obliquely upward. is there.

  According to the present invention, if the support shaft is moved to the holding portion formed on the open position side from the closed position of the guide groove, the support shaft is held so as not to move to the closed position side. For this reason, even if it does not support a spindle and a throwing door by hand, since a clearance gap can be ensured between a throwing door and a throwing mouth, a throwing thing and a hand can be pulled out still more smoothly.

A loading port apparatus of the present invention includes a loading port member in which a loading port is opened, a loading door that closes the loading port, a support shaft that pivotally supports the posting door, and the support shaft. A guide member having a guide groove that is movably guided in a direction crossing the axial direction of the support shaft, and a spring member attached to the support shaft and biasing the posting door in a direction to close the posting port; When the support shaft is in a closed position that is one end side of the guide groove, the posting port can be closed by the posting door, and the support shaft can be closed from the one end side to the other. When moved in the direction of the open position that is the end side, a gap is secured between the throwing door and the throwing port, and the spring member is constituted by a torsion coil spring, and the coil shaft of the torsion coil spring Is inserted through the support shaft and the torsion coil spring The first end is in contact with the inner surface of the posting port member, the second end of the torsion coil spring is characterized by abutting the inner surface of the mailing door.

According to the present invention, the spring member can be incorporated by inserting the coil shaft of the torsion coil spring through the support shaft, and the assembly workability can be improved.
Further, since each end of the torsion coil spring is in contact with the inner surface of the throwing port member or the throwing door, the support shaft can be moved smoothly without resistance when moving from the closed position to the open position. In particular, when the support shaft is moved from the closed position to the open position, if the support shaft moves in a direction away from the loading port, the contact force of the first end portion of the torsion coil spring to the inner surface of the loading port member is reduced. Weaken. For this reason, the urging force applied to the throwing door is weakened by the second end of the torsion coil spring, and the force with which the throwing door hits the throwing object or the hand can also be weakened.
Here, the inner surface is an inner surface of the posting port member or the door. Therefore, when the posting port device is provided on the post, the inner surface is the inner surface of the post. Moreover, when the posting mouth apparatus is provided in the entrance door, the said inner surface is a surface of the entrance door indoor side.

A loading port apparatus of the present invention includes a loading port member in which a loading port is opened, a loading door that closes the loading port, a support shaft that pivotally supports the posting door, and the support shaft. A guide member having a guide groove that is movably guided in a direction crossing the axial direction of the support shaft, and a spring member attached to the support shaft and biasing the posting door in a direction to close the posting port; When the support shaft is in a closed position that is one end side of the guide groove, the posting port can be closed by the posting door, and the support shaft can be closed from the one end side to the other. When moved in the direction of the open position that is the end side, a gap is secured between the posting door and the posting port, the support shaft is provided along the horizontal direction, and the guide member is The guide groove provided on the inner surface of the posting port member apart in the direction , It is formed in an arc shape to the open position from the closed position, an open position of the guide groove, characterized in that apart from the upper and and mailing port than the closed position of the guide groove.

  According to the present invention, since the guide groove is formed in an arcuate shape, the opening position of the guide groove is both the penetration direction of the doorway (for example, the prospective direction of the entrance door) and the vertical direction with respect to the closed position. It will be a distant position. Therefore, when the support shaft moves from the closed position of the guide groove toward the open position, the support shaft moves away from the throwing port and moves upward, so that the clearance dimension between the throwing door and the throwing port can be gradually increased. At this time, since the guide groove has an arc shape, the support shaft can be moved smoothly, and the throwing object and the hand can be pulled out more smoothly.

  In the present invention, the support shaft is provided along a horizontal direction, the guide member is provided on the inner surface of the posting port member apart in the left-right direction, and each guide member is provided on the inner surface of the posting port member. A fixed surface portion fixed, an upper surface portion extending from the upper end portion of the fixed surface portion in a direction away from the posting port, an inner surface portion extending downward from an end portion of the upper surface portion, and a lower end portion of the inner surface portion A lower surface portion extending in a direction approaching the posting port, and a partition portion extending upward from an end portion of the lower surface portion, a groove between the partition portion and the inner surface portion, and the fixed surface portion and the partition portion The guide groove is constituted by the groove between, the lower end portion of the groove between the partition portion and the inner surface portion is the closed position, and the holding portion is constituted by the groove between the fixed surface portion and the partition portion. Is preferred.

According to the present invention, the guide groove is formed by a vertical groove, and the lower end portion of the groove between the partition portion and the inner surface portion is a closed position. For this reason, when the support shaft is moved upward from the closed position of the guide groove toward the open position side, the gap dimension between the throwing door and the throwing opening can be gradually increased. At this time, since the guide groove is formed in the vertical direction, the thickness dimension in the opening direction of the insertion port of the guide member can be suppressed.
Further, since the holding portion (groove between the fixed surface portion and the partition portion) in the guide groove is continuous with the groove between the partition portion and the inner surface portion at the upper portion of the partition portion, if the support shaft is moved to the holding portion, Without automatically returning to the groove between the partition portion and the inner surface portion, the support shaft and the throwing door can be continuously held by the holding portion.

[First Embodiment]
DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, a first embodiment of the invention will be described with reference to the drawings.
FIG. 1 is a front view of the outside of the entrance door 1, and FIG. 2 is a schematic cross-sectional view showing a mailbox 2 provided on the entrance door 1.
The mailbox 2 is configured to include a posting port device 3 attached from the outside of the through-hole 1 </ b> A that penetrates the entrance door 1, and a receiving box 4 attached to the interior of the entrance door 1. ing. Since the receiving box 4 is a general one similar to the conventional one, the description thereof is omitted.

[Posting port device]
As shown in FIGS. 3 and 4, the posting port apparatus 3 includes a posting port member 10, a posting door 20, a support shaft 30, and a spring member 40.
FIG. 3 is a schematic view of the doorway device 3 as viewed from the indoor side, and FIG. 4 is a schematic cross-sectional view taken along line AA of FIG.

[Posting port materials]
The posting port member 10 is a plate-like member in which the posting port 11 is opened. A pair of left and right guide members 12 project from the room-side surface of the posting port member 10. The guide member 12 is formed in a plate shape (plate shape), and may be formed integrally with the posting port member 10 or may be fixed to the posting port member 10 with an adhesive or the like.

As shown in FIG. 4, the guide member 12 is formed with a long groove-like guide groove 121 that guides the support shaft 30.
The guide groove 121 includes a through-hole direction (expected direction) of the doorway 11, that is, an indoor / outdoor direction that is a through-direction of the through-hole 1A of the entrance door 1, and an axial direction of the support shaft 30 (horizontal direction in the present embodiment). Are formed continuously in a direction intersecting with. Specifically, the guide groove 121 is formed in an arcuate groove shape from the closed position at the lower end to the open position at the upper end in the direction along the opposing surface (vertical surface) of the guide member 12. The guide groove 121 is formed in a direction upward and toward the indoor side of the receiving box 4 as it goes from the closed position to the open position. That is, the guide groove 121 is continuously formed obliquely upward toward the indoor side.

  On the upper end of the guide groove 121, that is, on the open position side, a groove-shaped holding portion 122 that holds the support shaft 30 is formed. That is, the upper end side of the guide groove 121 is formed in a substantially horizontal direction, and a protrusion 123 protruding upward is formed on the lower surface thereof. Therefore, when the support shaft 30 moves in the guide groove 121 and moves over the protrusion 123 to the holding portion 122, the support shaft 30 is held because the protrusion 123 restricts the movement of the support shaft 30 toward the closed position. The state held by the portion 122 is maintained. Therefore, the support shaft 30 is held in the open position by being held by the holding portion 122.

[Spindle]
The support shaft 30 is formed of a round bar, and both ends thereof are inserted into the guide grooves 121 of the respective guide members 12. As shown in FIG. 3, both end portions of the support shaft 30 are crushed by caulking or the like, and are configured not to be detached from the guide member 12.

[Throwing door]
The posting door 20 is pivotally supported with respect to the support shaft 30 so as to be rotatable. The throwing door 20 includes a main body portion 21 that fits into the posting port 11, a protruding portion 22 that protrudes from the upper end portion of the main body portion 21 and is bent in an L shape, and a shaft insertion portion that continues from the protruding portion 22. 23.
As shown in FIG. 4, the main body portion 21 includes a fitting portion that protrudes toward the outdoor side and fits into the posting port 11. Therefore, the main body 21 can be manufactured by drawing a plate-like member.

As shown in FIG. 3, the protrusions 22 are provided at both left and right ends of the upper end of the main body 21.
The shaft insertion portion 23 is formed with a shaft hole through which the support shaft 30 is inserted. Therefore, the insertion door 20 is rotatably attached to the support shaft 30 by inserting the support shaft 30 through the shaft insertion portion 23.
The throwing door 20 is a door of an inward opening type because it is opened by being turned from the closed position for closing the posting opening 11 toward the indoor side of the receiving box 4.

[Spring member]
In the present embodiment, the spring member 40 is constituted by a one-step bending torsion coil spring. Therefore, the spring member 40 includes a coil shaft 41, a first end portion 42, and a second end portion 43. The support shaft 30 is inserted into the coil shaft 41 portion. Further, the first end portion 42 is in contact with the indoor surface as the inner surface of the posting port member 10, and the second end portion 43 is in contact with the indoor surface as the inner surface of the posting door 20.
As shown in FIG. 4, the spring member 40 has a predetermined biasing force (spring force) so that the door 20 does not open indoors due to wind or the like when the door 20 is closed. The posting door 20 is urged toward the outdoor side.

[Operation when posting items]
As shown in FIG. 5, when a posting object 100 such as a newspaper or a mail is posted to the posting port 11, the posting door 20 is pushed by the posting object 100 and resists the biasing force of the spring member 40. Rotate indoors. At this time, the posting door 20 opens to the indoor side in a state where the support shaft 30 is disposed at the closed position of the guide groove 121.

Further, when the throwing object 100 is pushed in, the throwing door 20 opens further indoors with the support shaft 30 as a rotation axis. Therefore, if the throwing object 100 is pushed in as it is, the throwing object 100 is put into the receiving box 4.
On the other hand, when the throwing object 100 passes through the through hole 1A and is completely put into the receiving box 4, the throwing door 20 closes the throwing opening 11 by the urging force of the spring member 40 (see FIG. 4). Return to the state.

[Operation when pulling out hand]
As shown in FIG. 6, when the throwing object 100 is pushed from the throwing slot 11 to the receiving box 4 or when a hand is mistakenly inserted into the throwing slot 11, the hand (finger) 200 is inserted into the throwing door 20 and the throwing slot 11. Or between the through hole 1A.
In this case, even if an attempt is made to pull out the hand from the posting port 11, a finger is caught on the posting door 20 urged by the spring member 40, and the hand 200 remains sandwiched, and it may be difficult to pull out from the posting port 11. .
Further, when a throwing object such as a newspaper is inserted into the posting port 11, when the throwing object is pulled out from the outside of the entrance door 1, the throwing object is sandwiched between the posting door 20 and the posting port 11. May end up. In this case, it may be difficult to pull out the posting.

On the other hand, in the present embodiment, the support shaft 30 is movable along the guide groove 121 as shown in FIG. For this reason, if the hand 200 is moved upward, the support shaft 30 is moved upward along the guide groove 121, and the posting door 20 is also moved upward. Therefore, the insertion door 20, the opening 11 and the through hole 1A A gap is formed between the two.
For this reason, it is possible to easily avoid a state in which the hand 200 is sandwiched between the posting door 20 and the posting port 11. In particular, the support shaft 30 is disposed at a closed position under its own weight and is not biased downward by a spring or the like. Therefore, the support shaft 30 and the door 20 can easily move along the guide groove 121 with a small force. Can be done.

Further, when the support shaft 30 and the posting door 20 are moved obliquely upward along the guide groove 121 and the support shaft 30 moves to the holding portion 122 beyond the protrusion 123, as shown in FIGS. The support shaft 30 is held in the open position.
For this reason, even if it does not support the mailing door 20 by hand, the clearance gap of a predetermined dimension can be ensured between the mailing door 20 and the mailing port 11, and the state can be maintained.

  Further, the holding state can be released by moving the throwing door 20 and the support shaft 30 held in the open position to the closed position side while moving upward and moving the support shaft 30 to the closed position side of the protrusion 123. Accordingly, if the hand is released in this state, the door 20 and the support shaft 30 move along the guide groove 121 to the closed position (the lowermost end) by its own weight, and the door 20 is opened by the urging force of the spring member 40. It returns to the position where the mouth 11 is closed (the state shown in FIG. 4).

[Effects of First Embodiment]
(1) In this embodiment, since the support shaft 30 is provided so as to be movable along the guide groove 121 of the guide member 12, the throwing object and the hand are sandwiched between the throwing door 20 and the throwing port 11, When trying to pull out from the outside (outside), the support shaft 30 and the throwing door 20 move along the guide groove 121. For this reason, when pulling out a throwing thing and a hand from the throwing slot 11, it can pull out easily.
In particular, in the present embodiment, the support shaft 30 itself is not biased toward the closed position by the spring, and therefore, a large force is not required when moving the support shaft 30 from the closed position toward the open position. For this reason, even if a child's hand is pinched, the spindle 30 and the posting door 20 can be moved along the guide groove 121 with the help of the child, and the hand can be easily pulled out from the posting port 11.

(2) Since the holding portion 122 is formed closer to the open position than the closed position of the guide groove 121, the support shaft 30 that has moved to the open position can be held by the holding portion 122. If the support shaft 30 is held by the holding portion 122, an opening (gap) can be secured between the throwing door 20 and the throwing port 11 without supporting the throwing door 20 by hand. Therefore, it is possible to prevent the throwing door 20 from constantly hitting the throwing object or the hand when the throwing object or the hand is pulled out from the throwing port 11, and the throwing object or the hand can be pulled out more smoothly.
Further, the holding portion 122 is formed by providing a protrusion 123 on the lower surface of the guide groove 121, and the support shaft 30 can be easily moved to the holding portion 122 or removed from the holding portion 122. Therefore, it is possible to easily return the posting door 20 and the support shaft 30 held in the open position to the original closed position.

(3) Since the guide groove 121 is formed in a substantially arc shape, as the support shaft 30 is moved from the closed position to the open position, not only the support shaft 30 but also the inside of the receiving box 4 (away from the loading port 11). Direction). For this reason, the posting door 20 can be gradually separated from the posting opening 11 to the indoor side (inside) to form a gap.
Further, the spring member 40 presses the second end portion 43 against the loading door 20 and urges the first end portion 42 against the loading port member 10. Therefore, this urging force increases as the distance between the support shaft 30 and the first port portion 10 with which the first end 42 abuts is smaller. For this reason, when the support shaft 30 moves toward the opening position of the guide groove 121 and moves away from the throwing port member 10, the biasing force applied to the throwing door 20 by the spring member 40 is also reduced.
Accordingly, the urging force by the spring member 40 is reduced by forming the guide groove 121 in a substantially arc shape so that the support shaft 30 moves upward and indoors (inside) from the closed position to the open position. In addition, the gap between the posting port 11 and the posting door 20 can be increased. For this reason, a throwing thing and a hand can be pulled out still more easily.

(4) The loading port apparatus 3 can be configured by attaching the loading door 20 and the spring member 40 to the support shaft 30 and further attaching the support shaft 30 to the guide groove 121 of the guide member 12 of the loading port member 10. For this reason, the port apparatus 3 can be configured only by mounting the port door 10 to which the door 20, the support shaft 30, and the spring member 40 are mounted in the through hole 1 </ b> A of the entrance door 1. For this reason, it is not necessary to provide a special structure on the through hole 1A side of the front door 1, and the construction can be easily performed. In addition, the existing entrance door 1 can be easily replaced and installed.

At this time, the loading door 20A opens to the indoor side in a state where the support shaft 30A is disposed at a closed position of the guide groove 130 (a position where the guide groove 130 abuts the lower surface portion 128 connecting the inner surface portion 127 and the partition portion 129).

Further, when the throwing object 100 is pushed in, the throwing door 20A is further opened indoors with the support shaft 30A as a rotation axis. Therefore, if the throwing object 100 is pushed in as it is, the throwing object 100 is put into the receiving box 4.
On the other hand, when the throwing object 100 passes through the through-hole 1A and is completely put into the receiving box 4, the throwing door 20A closes the throwing opening 11A by the urging force of the spring member 40A (FIG. 11). Return to the state.

[Operation when pulling out hand]
As shown in FIG. 13, when the throwing object 100 is pushed into the receiving box 4 from the throwing slot 11A or when a hand is accidentally inserted into the throwing slot 11A, the hand (finger) 200 is inserted into the throwing door 20A and the throwing slot 11A. Or between the through hole 1A.

In the present embodiment, as shown in FIGS. 14 and 15, the support shaft 30 </ b> A is movable along the guide groove 130. For this reason, if the hand 200 is moved upward, the support shaft 30A moves upward along the guide groove 131 of the guide groove 130, and the posting door 20A also moves upward. A gap is formed between the through hole 1A.
For this reason, it is possible to easily avoid a state in which the hand 200 is pinched by the throwing door 20A and the throwing port 11 or the like. In particular, the support shaft 30A is placed in a closed position under its own weight and is not biased downward by a spring or the like. Therefore, the support shaft 30A and the door 20A can easily move along the guide groove 130 with a small force. Can be done.

Further, when the support shaft 30A and the loading door 20A are moved upward along the guide groove 131 of the guide groove 130, the support shaft 30A moves beyond the partition portion 129 to the holding groove 132 between the fixed surface portion 125 and the partition portion 129. As shown in FIG. 16, the upper surface side of the projecting portion 22A is brought into contact with and locked with the throwing port member 10A, the supporting shaft 30A is held in the open position, and the throwing door 20A is maintained in the inwardly open state.
For this reason, a clearance gap can be ensured between the posting door 20A and the posting port 11A, and the state can be maintained.

  Further, the holding state can be released by moving the posting door 20A and the support shaft 30A held in the open position upward to the guide groove 131. Therefore, if the hand is released in that state, the throwing door 20A and the support shaft 30A move to the closed position (lowermost end) along the guide groove 131 by their own weight, and the throwing door 20A is thrown by the urging force of the spring member 40A. It returns to the position where the mouth 11A is closed (the state shown in FIG. 11).

[Effects of Second Embodiment]
According to the posting port apparatus 3A of the second embodiment, the same operational effects as those of the first embodiment can be obtained.
(1) In other words, in the second embodiment, the support shaft 30A is provided so as to be movable at least in the vertical direction along the guide groove 130 of the guide member 12A. Because of being sandwiched between them, the support shaft 30 </ b> A and the throwing door 20 </ b> A move upward along the guide groove 131 of the guide groove 130 when trying to pull out from the throwing side (outside the throwing port 11 </ b> A). For this reason, when pulling out a throwing thing and a hand from the posting opening 11A, it can pull out easily.
In particular, in the present embodiment, the support shaft 30A itself is not biased to the closed position by the spring, so that a large force is not required when the support shaft 30A is moved from the closed position toward the open position. For this reason, even if a child's hand is pinched, the spindle 30A and the throwing door 20A can be moved along the guide groove 130 with the help of the child, and the hand can be easily pulled out from the throwing port 11A.

(2) Since the holding groove 132 is formed in the guide groove 130 and the support shaft 30A is moved to the holding groove 132, the protruding portion 22A comes into contact with the loading port member 10A, so the loading door 20A is held by the holding groove 132 portion. can do. If the support shaft 30A is moved from the guide groove 131 to the holding groove 132 and the projecting portion 22A is brought into contact with the loading port member 10A, the main body portion 21A can be held in the inwardly opened state. For this reason, an opening (gap) can be maintained between the posting door 20A and the posting port 11A. Accordingly, it is possible to prevent the throwing door 20A from constantly hitting the throwing object when the throwing thing or hand is pulled out from the throwing port 11A, and the throwing thing or hand can be pulled out more smoothly.
Furthermore, the guide groove 131 and the holding groove 132 are only partitioned by the partition portion 129, and the support shaft 30 </ b> A is moved from the guide groove 131 to the holding groove 132 or moved from the holding groove 132 to the guide groove 131. Can also be done easily. Accordingly, it is possible to easily return the posting door 20A and the support shaft 30A held in the open position to the original closed position.

(3) Since the guide groove 130 is formed in the vertical direction, the size of the guide member 12A in the expected direction can be reduced. For this reason, even when the thickness dimension of the entrance door 1 is small, the posting port apparatus 3A can be easily incorporated.

(4) The loading port apparatus 3A can be configured by mounting the support shaft 30A to which the loading door 20A and the spring member 40A are mounted in the guide groove 130 of the guide member 12A of the loading port member 10A. For this reason, the insertion port apparatus 3A can be configured only by attaching the insertion port member 10A to which the insertion door 20A, the support shaft 30A, and the spring member 40A are attached to the through hole 1A of the entrance door 1. For this reason, it is not necessary to provide a special structure on the through hole 1A side of the entrance door 1, and the construction work is easy. In addition, the existing entrance door 1 can be easily replaced and installed.

(5) Since the lower end of the holding groove 132 of the guide member 12A is opened, the support port 30A can be inserted from the lower end opening of the holding groove 132 to assemble the loading port apparatus 3A, and the assembling workability can be improved.
