The purpose of the receiver is to provide a locking device for use.

To explain the embodiment, reference numeral 1 is a storage space formed in an entrance door, a sleeve part of a single door, or a child door part of a parent-child door. A weight-closing type article receptacle 3 is attached so as to be rotatable outward by a hinge mechanism 2 fixed to the holder.

The article receiver 3 is composed of a lid plate 4 that forms the outer wall surface of the door in the closed state, and an article storage section 5, and an upper stile 6 is provided at the upper end of the lid plate 4 at a position corresponding to the upper stile 7 on the door side. is formed.

The storage space 1 is partitioned by an upper partition plate 8a and a lower partition plate 8b, which are attached to the door or the sleeve side at both upper and lower ends, and on the indoor side, milk, etc. stored in the goods storage part 5 are stored. An internal door 9 is provided for taking out the contents.

Reference numeral 10 denotes a long hole formed in the side wall of the article storage section 5 in an arc shape with the hinge mechanism 2 as the center of rotation. A provided guide pin 11 is inserted through the guide pin 11 to regulate the maximum opening ratio of the upper end portion of the article receiver 3.

12 is a top catch mounting plate fixed near the upper end of the inner surface of the article receiver 3 by spot welding or other means;
The top catch body 1 is provided with a latch insertion hole 14 in the central protrusion 12a of the top catch mounting plate 12.
3 is screwed with screws 15 and 15.

A long hole 16 is provided in the indoor vertical surface 13a of the top catch body 13 from the center to the vicinity of the lower end, and a piece 17 bent inward is formed at the upper end of the long hole 16. has been done.

Reference numeral 18 denotes a pin held on both side walls of the top catch main body 13 to prevent it from falling off.One end 19a of a spring receiver 19 bent into a shape is attached to the pin 18. The other end protrusion 19b of the seat 19 is held by a bent piece 17 formed at the upper end of the elongated hole 16.

Reference numeral 20 denotes a latch made of a thin plate made of stainless steel or the like, and only the retaining portion 20 a that slopes toward the indoor side is formed into a bag shape by bending the thin plate;
The latch thin plate portion 20b extending downward from the top catch body 13 is provided with an elongated hole 21 whose width is somewhat larger than that of the elongated hole 16 of the top catch body 13, and the length of the latch thin plate 20b ( A lever 22 is inserted through L21 and the elongated hole 16 of the top catch body 13 and has one end rotatably held by the pin 18. A hook ring 23 is attached to the end.

Engagement portion 2 of spring seat 19 and bag-shaped latch 20
0a, the latch 20 is connected to the top catch body 1.
a coiled spring 2 that urges it to protrude outward from 3;
4 is inserted, and the stability of the spring 24 during insertion is ensured by a protrusion 25 provided on the spring seat 19.

A latch thin plate portion that projects downward from the top catch body 13 when the engaging portion 20a of the latch 20 is pushed down by the hook ring 23 attached to the lever 22 against the biasing force of the spring 24. A lock pin insertion hole 26 is opened in the part 20b, and the insertion hole 26 is

8 with the tip slightly tilted downward.

Therefore, when the lock pin 28 is inserted into the insertion hole 26 of the latch thin plate portion 20b to hold the top catch mounting plate 12 (when held at L27, the engagement portion 20 of the latch 20
a is pushed down into the top catch body 13 and released from engagement with the upper stile 7.

A chain attachment hole 29 is provided in the head 28 a of the lock pin 28 , and a locking hook 31 is attached to the other end of a chain 30 of a predetermined length that is attached to the attachment hole 29 . There is.

Reference numeral 32 denotes a locking tool provided on the upper partition plate 8a near the internal door 9. When the hook 31 is engaged and held by the locking tool 32, the locking tool 32 closes the chain 3 before the article tray 3 is fully opened.
0 is held in the extended state, and the lock pin 28 is pulled out from the insertion hole 26 of the latch thin plate portion 20b for further openings, and the latch 20 can move freely, so that the latch 20 is not engaged. The portion 20a is projected upward from the top catch body 13 by the biasing force of the spring 24.

Reference numeral 33 denotes another locking device provided in front of the locking device 32 on the upper partition plate 8a, and when the hook 31 is engaged with and held in the locking device 33, the locking device 33 closes the article receiver 3 when it is fully opened. At the same time, the lock pin 28 is inserted into the insertion hole 26 of the thin plate portion 20b.
The engaging portion 20 a of the latch 20 is kept engaged with the latch 20 .
The top catch body 13 regardless of whether the article tray 3 is opened or closed.
hold within.

Next, how to use this article receptacle 3 will be explained.

There are three possible ways to use it: Firstly, the first way to use it is to open it from the outside when placing milk or the like into the container 3, but once the milk or the like is stored and the container is closed to its original state, the container 3 is automatically locked. The second usage is when the article tray 3 can be opened and closed freely as many times as desired, and the third usage is when the article tray 3 is not used as the original article tray 3, This is a case where it is always kept closed.

When using the first method, insert the latch into the insertion hole 26 of the thin latch plate 20b and the holding hole 2 of the top catch mounting plate 12.
The locking hook 31 of the lock pin 28 held by 7 is
What is necessary is just to hook it to the locking tool 32 fixedly installed in the upper partition plate 8a.

In this case, the chain 30 becomes stretched before the article tray 3 is fully opened, and applies a tensile force to the lock pin 28 against further opening. The pin 28 is pulled out from the insertion hole 26 and the holding hole 27, and the latch 20 becomes freely movable.

For this reason, once the article receptacle 3 containing milk or the like is closed, the latch 20, the tip of the engaging portion 20a of which is inclined toward the indoor side, engages with the upper stile 7 on the door side and closes the door. Subsequent opening of the article receptacle 3 can be automatically prevented.

To make the article receptacle 3 openable again, the lever 22 is rotated around the pin 18 by the hook ring 23 to push down the latch 20, and the lock pin 28 is pushed into the latch thin plate portion 2.
Insert into the insertion hole 26 of 0b and attach the top catch mounting plate 1.
Hold it in the holding hole 27 of 2 and attach it to the upper stile 7 on the door side and the latch 20.
All you have to do is release the engagement and return to the initial state.

In the case of the second usage, the locking hook 31 of the lock pin 28 engaged with the latch 20 is fixedly provided in front of the locking tool 32 in the same manner as in the first usage. All you have to do is hook it to another locking tool 33.

In this case, even if the article tray 3 is fully opened, the chain 30
is kept in a relaxed state and the locking pin 28 is held in the latch 20.
Since the latch 20 and the upper stile 7 do not disengage from each other even when the article receiver 3 is closed, the latch 20 and the upper stile 7 do not engage with each other.
The article receptacle 3 can be opened and closed as many times as desired.

For the third usage, it is sufficient to simply release the lock pin 28 from engagement with the insertion hole 26 of the latch thin plate portion 20b.

In this way, the latch 20 is pushed upward by the biasing force of the spring 24 and engages with the upper stile 7 on the door side. Therefore, the article receptacle 3 is always kept closed.

In addition, in the above-mentioned first usage, if you want to eliminate the inconvenience of accidentally closing the article receptacle 3 and not being able to store the forgotten items, the delivery person and the resident may discuss and close the article receptacle 3. In the second method described above, the delivery person may remove the lock pin 28 from the insertion hole 26 of the latch 20 after storing the article.

In this case, the delivery person can freely open and close the article receiver 3 as many times as he wants until he releases the lock pin 28.
