As shown in the perspective view of FIG. 4, the load receiving body 8 includes a vertical plate 9 and a T-shaped plate 10 as a load receiving portion integrally provided substantially vertically to the upper end of the vertical plate 9. A projecting piece 12 which is provided substantially at the center of the vertical plate 9 so as to project to both rear sides and has a long hole 11 formed in a direction along the vertical plate 9;
A support shaft portion 13 that is rotatably fixed to the door body 1 at both lower ends, and a first horizontal shaft 14 that is installed between the support shaft portions 13.
And a second horizontal shaft 15 that is installed so as to pass through both of the long holes 11, and in front of the vertical plate 9 at approximately the center of the installation position of the first horizontal shaft 14 and the second horizontal shaft 15. The third horizontal shaft 16 is arranged, the support shaft portions 17 provided at both ends of the third horizontal shaft 16 and the support shaft portions 13 at both ends of the first horizontal shaft 14 are respectively rotated at their ends. The first connecting shaft 18 movably provided, the support shaft portions 19 provided at both ends of the second horizontal shaft 15 and the support shaft portions 17 at both ends of the third horizontal shaft 16 have end portions. The second connecting shaft 20 is rotatably provided.

As shown in FIG. 5, the bent portion 10a at the tip of the T-shaped plate 10 is a recess 21a of an elastic locking body 21 projecting on the rear side of the door body 1 when no load is received.
Is locked to the first opening so as to face the inlet 3.
A space A formed by the horizontal axis 14 and the third horizontal axis 16 of
In addition, the third horizontal shaft 16 is held in a state where it does not contact the front side of the vertical plate 9.

The operation of the luggage receiver 8 when in use will be described.

When the shutter plate 4 is moved upward by the knob 4a and the package N is inserted through the opening 3 in the state shown by the solid line in FIG. 3, the front end of the package N pushes the vertical plate 9 to the rear side. The engagement between the bent portion 10a and the recess 21a of the elastic engagement body 21 is released by the pressing force. Further, when the load N is inserted, the load N is moved from the space A formed by the first horizontal axis 14 and the third horizontal axis 16 to the third horizontal axis 16 as shown by a two-dot chain line B1 in FIG. And the front side of the vertical plate 9 through the T-shaped plate 1
Move to 0 side. Then, as indicated by a chain double-dashed line B2 in FIG.
Is rotated counterclockwise about the central axis and comes into contact with the back side of the door body 1. In this state, the load N is placed on the vertical plate 9
That is, the T-shaped plate 10 and the third horizontal shaft 16 are held without falling and stored inside the door.

After the baggage N is taken from the baggage receiving body 8, the vertical plate 9 is rotated clockwise about the first horizontal shaft 14 so that the bent portion 10a of the T-shaped plate 10 is elastically locked. By re-engaging with, it can be in a standby state until receiving the next luggage.

The positions of the inlet 3 and the space A are set, and the third horizontal axis 16 is set so as to be positioned above the load N without coming into contact with the front side of the vertical plate 9. In order to ensure the insertion and holding of the load N, the bent portion 10a of the T-shaped plate 10 is locked to the elastic locking body 21. However, the elastic locking body 21 is not limited to being used.

FIG. 6 is a side cross-sectional view of the insertion port portion. Inside the door body 1 at the insertion port 3 portion, there is provided a guide frame 30 for guiding the shutter plate 4 so as to be vertically movable. A receiving hole 32 into which an elastic protrusion 31 fixed to the upper portion of the shutter plate 4 is fitted is formed in the upper end portion of the guide frame 30, and the upper end of the shutter plate 4 in the closed state is located at the side portion of the guide frame 30. A through hole 33 is formed in the portion to be formed.

A lock shaft 36 supported by a pair of upper and lower rotary support plates 35 is provided in a space 34 along the guide frame 30 inside the door body 1 as shown in the perspective view of FIG. . At the upper end of the lock shaft 36, as shown in FIG. 8, an L-shaped lock portion 37 is provided so as to project perpendicularly to the lock shaft 36 so that the tip 37a faces the through hole 33. As shown in FIG. 9, at the lower end of the lock shaft 36, a tip 38a faces the side opposite to the tip 37a of the L-shaped lock portion 37, and further, at the rear side of the door body 1, the luggage receiver 8 carries the luggage. An L-shaped operation portion 38 is provided perpendicular to the lock shaft 36 so as to face a through hole 39 formed in a position where the vertical plate 9 rotates and hangs down when received.

FIGS. 6, 8 and 9 show in a solid line a state in which no load is placed in the load receiver 8. The L-shaped operating portion 38 of the lock shaft 36 receives the pressing force of the spring 40. Thus, the tip 38a is exposed from the through hole 39 on the rear side of the door body 1. On the other hand, the L-shaped lock portion 37 of the lock shaft 36
Has its tip 37a separated from the upper end of the shutter plate 4,
It is located in the through hole 33 portion.

When the shutter plate 4 is moved upward while holding the knob 4a in order to load the luggage into the loading slot 3, the elastic projection 31 on the upper part of the shutter plate 4 is fitted into the receiving hole 32 at the final position of movement of the shutter plate 4. The downward movement of the shutter plate 4 is locked and the opening state of the loading slot 3 is maintained, so that the shutter plate 4 does not become an obstacle when handling luggage. If the shutter plate 4 is pulled strongly downward, the elastic protrusions 3
1 is disengaged from the receiving hole 32, the shutter plate 4 can be moved, and the insertion port 3 is closed.

Here, when the luggage is loaded into the luggage receiving body 8 as described above, the vertical plate 9 rotates and comes into contact with the rear side of the door body 1. At this time, the pressing force of the vertical plate 9 is applied. The L-shaped operation portion 38 receives the tip end 38a, rotates counterclockwise against the pressing force of the spring 40, and enters inward (see FIG. 9). This rotation causes the lock shaft 36 and the L-shaped lock portion 37 to rotate in the same direction, and the tip 37a of the L-shaped lock portion 37 has a through hole 33.
The shutter plate 4 projects from above to the upper end of the shutter plate 4 (indicated by the chain double-dashed line in FIG. 8). In this state, even if an attempt is made to move the shutter plate 4 upward, the shutter plate 4 cannot move due to the presence of the tip 37a. That is, when the luggage is already loaded in the luggage receiver 8, the shutter plate 4 is held in the closed state. By doing so, theft can be prevented.

[0020]

As is apparent from the above description, according to the present invention, the shutter cannot be opened from the outside after the load is received by the load receiving body by the lock shaft, and the load receiving is effective for theft prevention. An entrance door can be provided.
