The present invention relates to an automatic lock delivery box comprising: a stopper means between the outer case and the rotating plate; and an opening and closing means for opening and closing the opening on the other surface. This is a means for solving the above problems. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in more detail with reference to the drawings showing the embodiments. In FIGS. 1 to 3, A is made of metal, and is mounted and fixed on a column, for example, and embedded in a gate column. A delivery box installed or installed at a gate or entrance through a base, and the like, 10 is its outer case, 14 is a slide frame, and 18 is for loading luggage, that is, for receiving luggage. Rotating plate, 22 is stopper means, 2
Reference numeral 5 denotes opening / closing means. The outer case 10 has two upper and lower openings 11, 12 on the two surfaces, that is, on the front and rear surfaces in this example.
And a guide means, for example, a slide rail 13 is additionally provided for each of the front and rear openings 11 and 12. The slide frame 14 has a rectangular shape with a door wheel 15 and a guide rib 16 on the side surface of the slide rail 13 in accordance with the vertical and horizontal inner dimensions of the outer case 10. Is provided with an upright wall 17 for closing the front side opening 11. In this example, the upper and lower slide frames 14 are used. In the above configuration, the opening 11 on one surface of the outer case 10, that is, the front surface,
The outer case 10 is housed in the outer case 10 so that it can be pulled out from the front. The rotating plate 18 is provided for the slide frame 1.
4, a plate having a rigid structure or material whose length and width are adjusted to the slide frame 14 so as to form a bottom plate thereof, and a rotating plate 18
Is to form a luggage receiving seat which is pivotally fixed to the slide frame 14 so that it can swing freely depending on the presence or absence of the luggage mounting load. That is, in this embodiment, the rotating plate 18 is integrally provided with a rotating shaft 19 protruding right and left by welding at a rear surface position deviated to the rear side in the middle of the drawing direction. The driving shaft 19 is connected to the bearing 2 on the side wall of the slide frame 14.
The pivot plate 18 is fixed by the above-mentioned pivot support, and the rotation plate 18 is further provided with a balancer 21 at the rear end corresponding to the deviation of the pivot position, so that the front end is slightly upward. The tilted state is set to a normal state. As a result, the rotating plate 18 moves the load B
By applying the mounting load and removing the same, the front end of the slide frame 14 becomes rotatable in the slide frame 14 so as to swing. The stopper means 22 prevents the slide frame 14 from being pulled out of the opening 11 of the outer case 10 by the rotation of the rotation plate 18 due to the load of the load B. It is provided between them. In this embodiment, the stopper means 22
Is constituted by a front frame 22 for opening division provided at each lower end of the front side opening 11 of the outer case 10 and a contact wall 24 at the front end of the rotating plate 18. That is, the rotation plate 18 is inclined by the balancer 21 when there is no load on the luggage so that the slide frame 14 can be pulled out. When the load B is placed on the front end, the load B rotates horizontally or slightly downward so as to descend the front end. In this state, if the slide plate 14 is pushed into the outer case 10 so that the rotation plate 18 can get over the front frame 23 of the outer case 10, the rotation plate 18 is As a result, the contact wall 24 of the rotating plate 18 is brought into contact with the rear surface of the front frame 23 and is prevented from moving forward. At this time, since the rotating plate 18 is pivotally fixed to the slide frame 14, this contact stop prevents the slide frame 14 from moving with respect to the outer case 10, so that the slide frame 14 cannot be pulled out. Locking, ie, self-locking. The opening / closing means 25 is an upper / lower one-sided door hingedly connected to the outer case 10 in this embodiment, which closes the other surface of the outer case 10, that is, the opening 12 on the back side, in such a manner as to be freely opened and closed. Locking is performed as necessary. Accordingly, the automatic lock delivery box A of the present embodiment
By using the front side opening 11 as a luggage receiving port and the back side opening 12 as a luggage taking-out port, a deliverer such as a courier service pulls out the slide frame 14 to place the load B, and then places the slide frame 14 on the slide frame 14. Rotating plate 1
8, the slide frame 14 is automatically locked so that it cannot be pulled out again to prevent theft of the load B, etc.
5 to remove the load B, the rotation plate 1
8 returns to the normal state, the lock is automatically released, and the slide frame 14 can be pulled out again. In the drawing, reference numeral 26 denotes a stopper which defines a range of rotation of the rotating plate 18. FIG. 4 shows another example of the rotating plate 18 and the stopper means 22. In this embodiment, the rotating plate 18 is pivotally fixed at the rear end and the front end is inclined slightly upward as described above. The state is normal, but this inclined state is maintained by a spring 27 instead of the balancer 21. That is, a spring 27 is interposed between the spring back 28 projecting or extending in the opposite direction at a position corresponding to the front rear surface of the rotating plate 18 and the slide frame 14 so as to be compressible. Similarly, the rotating plate 18 is lowered by the application of the load, and the normal state is restored by removing the rotating plate 18. At this time, the stopper means 22 includes a downward projection 29 protruding from the lower surface of the front end of the rotating plate 18 and a receiving groove 30 provided near the front frame 23 of the outer case 10.
As described above, the slide frame 14 cannot be pulled out of the outer case 10 by engaging the downward projection 29 with the receiving groove 30 by the rotation of the rotation plate 18 due to the load placed on the load B as described above. , And is automatically released when the package B is taken out. The rest is the same as in the above example, so the same reference numerals are given and the description is omitted. Although the illustrated example is as described above, in the embodiment of the present invention, the opening of the outer case is defined as the opening position of the baggage outlet, for example, the front and the side or the front and the top. The other two surfaces can be used. Also, for example, the openings are installed in multiple stages, for example, three stages, installed in multiple rows in the left-right direction, and furthermore, the mail box is installed above the outer case. It can be various. The pivot frame can be fixed to the slide frame by supporting the projecting shaft of the slide frame on the bearing of the pivot frame. The pivot-fixed positions are the center and the front end of the slide frame. Alternatively, it can be set at an arbitrary position such as the rear end. When the pivot is fixed at the center position, the counterbalance itself can be obtained, so that measures for maintaining the normal state of the rotating plate can be omitted. Therefore, it is generally necessary or desirable to take measures to maintain normal conditions. As measures for maintaining the normal state, in addition to the above-mentioned support by the balancer and the spring, the suspension by an elastic material such as a spring and a telescopic rope, the support by a leaf spring, and the pulley connection with the balancer are simple, but the rotation is further stabilized. For this purpose, a link, a gear and the like may be used at the same time. The stopper means only needs to lock the rotating frame to the outer case, and the downward projection of the rotating frame can be brought into contact with the receiving projection on the side wall of the outer case. When the pivotal support position of the rotating plate is at the front end, the stopper means installation position can be arbitrarily determined so that the stopper means is at the rear end or intermediate position. Further, the slide frame is provided with a rising wall of an appropriate height at a side portion or a rear end,
The rotating plate is a mesh plate or a lattice plate, the rotating plate is rotated upward by the load of the load, and the stopper is provided at the position. Taking measures, using an outer case made of mortar, synthetic resin such as glass fiber reinforced resin, etc., using a hinge mechanism to fix the pivot of the rotating plate,
In the practice of the present invention, including the use of shutters, sliding doors and the like for the opening and closing means, the opening, outer case, slide frame, rotating plate, shaft support means, stopper means,
The specific shape, structure, material, dimensions, quantity, relations, additions, and the like of the opening / closing means can be variously changed without departing from the gist of the invention, and is particularly limited to the examples described above. Not enough. As described above, according to the present invention, the outer case having the opening on each of the two surfaces, the outer case is housed in the outer case so as to be able to be pulled out forward from the opening on one surface, and the opening is closed. Frame having an upright wall for use, a pivot plate for loading the luggage that is pivotally fixed to the slide frame so as to swing freely according to the presence or absence of the load, and a rotation by the luggage loading load A stopper means is provided between the outer case and the rotating plate for preventing the slide frame from being pulled out of the opening of the outer case by the rotation of the plate, and an opening / closing means for opening and closing the opening on the other surface. Because of the feature, it can be structurally automatically locked by receiving the package, and can also be structurally automatically released by removing the package.
