Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to mailboxes, and is particularly suitable for use by stacking and arranging them next to entrance halls or stairs in office buildings, condominiums, etc., or by embedding them in the walls thereof.

[Conventional technology]

In the past, various improvements have been made to the shape, structure, and auxiliary equipment of mailboxes, and they are now in practical use. For items with a door, when removing the mail, open the door with one hand and hold it so that it does not close.
The mail must be retrieved with the other hand, and when the door is closed, the safety of the mail cannot be maintained because there is no locking device.Also, even if the door has a locking device, it can be locked and unlocked with one touch. Not only is there no way to do this, but after the lock is locked, the lock randomly protrudes in front of the access door, and the user has to carry the key around, which can get in the way, risk losing it, and prepare multiple duplicate keys. There was a drawback that it was necessary to do so.

[Problems to be solved by the invention]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a mailbox in which a locking device is attached to the take-out door of the mailbox, and the door can be held open near its opening limit when taking out mail.

[Means to solve the problem]

In order to achieve the above-mentioned object, the mailbox of the present invention has an inward-opening drop-off door hanging from the upper front of the box-shaped mailbox main body, and a lower part of the mailbox door has a drop-open door attached above the mail-box. A mailbox with a hinged takeout door that opens and closes using an edge as a fulcrum, and a latch receiver in which a rotary dial lock latch attached to the takeout door is provided at the lower front end of the mailbox body. The hinge of the outlet door is connected to a rotary fitting attached to the outlet door and a fixed fitting attached to the mailbox body. The rotating fitting loosely fits a steel ball biased by a spring into its predetermined position, and moves the steel ball to the recess of the fixing fitting at a position near the opening limit due to the rotation of the outlet door. The device is characterized in that the outlet door is held in an open state.

[Effect]

Mail deposited in the mailbox is safe because the extraction door is locked with a rotary dial lock, so it will not be taken away by mistake or be stolen. When unlocking, you only need a PIN number and no key.
Therefore, the hassle of carrying around the key and the fear of losing it are eliminated. Furthermore, the hinge that opens and closes the take-out door in a rotational manner has a holding mechanism using steel balls biased by a spring to keep the open state stationary. It can be held stationary nearby, and you can open the door and take out mail with one hand.

【Example】

Next, the present invention will be explained in detail with reference to embodiments shown in the drawings. 1 to 3 schematically show a mailbox according to the present invention. Reference numeral 1 denotes the main body, which in this embodiment has a large capacity to accommodate A4-sized mail even if you are away for several days.A mailbox door 2 that opens inward is attached to the upper front of the main body. Further, at the bottom of the mailbox door, a takeout door 3 equipped with a rotary dial lock 4 is hinged to the main body 1 so as to be opened and closed using its upper edge as a fulcrum. Mail is deposited into the mailbox from the mailbox door 2, and to take it out, match the numbers on the rotary dial lock using the recited number, pull the takeout door upwards, and take out the mail.
It is pulled up to a position close to the upper limit, for example around 110 degrees, and then stopped there to be taken out. Figures 4 and 5 show mailbox door 2 and extraction door 3.
Shows how it opens and closes. As shown in FIG. 8, the mailbox door 2 has a lid 8 having grooves 10 and 11 into which a name tag 12 is inserted, and is hinged to the main body 1 by a shaft 9, and is hung so as to open inward as shown by the chain line in FIG. ing. Lid 8
uses transparent acrylic material, so grooves 10,
The information written on the name tag inserted into the 11 can be clearly seen from the outside, and the name tag itself is difficult to get dirty. The upper edge of the outlet door 3 is attached to the main body 1 by a hinge 5, and the hinge is used as a fulcrum to open the mailbox to the outside of the mailbox. A protruding latch 20 engages a latch receiver 23 to maintain the closed condition. This latch 20 is activated when the outer ring 14
The inner ring and the outer ring are rotated while hooking the claws 15 provided on the inner ring 16 and the claws 17 provided on the inner ring 16, and the latch grooves 18 cut in both rings and the latch provided in the inner ring in the perspective view of FIG. Although the grooves are not shown because they are covered by the outer ring, the latch grooves of both rings are aligned and stop in a position to receive the latch, allowing the latch to enter into both rings. That is, this is the unlocked state of the rotary dial lock 4. Next, to explain how to lock the lock, if you turn the dial 13 in either the left or right direction or both directions, the inner ring and outer ring will both rotate by the claws 15 and 17, and the position of the latch groove will move to another point. do. The latch is then prevented from advancing towards both rings, ie it becomes locked. In this example, since two inner and outer rings are combined, the number of combinations of PIN numbers is small, but the number of combinations can be increased significantly by increasing the number of rings. 21 is a washer, and 22 is a nut for attaching the rotary dial lock to the exit door 3. Next, details of the hinge that maintains the open state of the outlet door 3 will be described. As shown in FIGS. 9 and 10, the hinge provided on the outlet door 3 is connected to a rotating metal fitting 28, which is a substantially crank-shaped piece attached to the side of the outlet door 3, and a rotating metal fitting 28 that is attached to the side of the mailbox body 1. The outlet door 3 is connected to the fixing bracket 27 to be attached, and the outlet door 3 is connected to the fixing bracket 27.
7 and the rotating fitting 28 are rotated about their axis 36 by a screw 35. The rotating fitting 28 has holes 30 on the left and right sides of the screw holes for the screws 35, into which the steel balls 31 are loosely fitted, and the loosely fitted steel balls 31 are held by the disc spring 32 and the spring receiver 32. It is pressed into contact with the surface side of the fixing metal fitting 27 and is biased. Further, a recess 29 such as a hole or a recess into which the steel ball 31 is moved and loosely fitted is formed in the fixing metal fitting 27, and the rotating metal fitting 28 is rotated as shown in FIG. As shown, when reaching the opening limit position, that is, near the mailbox door 2, the hole 30 of the steel ball 31 housed in the rotating fitting 28 and the recess 29 of the fixing fitting 27 match, and the steel ball A portion of the ball 31 moves into the recess 29 and is loosely fitted, and the ball 31 maintains that state, that is, the open state of the outlet door 3, unless an external force is applied to the outlet door 3. To release this stationary state, when an external force is applied by hand in the closing direction, the steel ball is restrained within the hole 30 and is forced to escape from the recessed portion against the disk spring, and the gravity of the exit door due to its own weight. It is in a state of falling.
37 is a screw for fixing the fixing fitting to the frame body 26. In addition, 6 is a mounting hole for connecting and fixing the main bodies to each other or to a building structure, 7 is an embossed protrusion so as to float the mailbox against the bottom plate 38,
Reference numeral 24 denotes an inclined surface of the frame body that allows the mail to be taken out smoothly.
