CROSS-REFERENCE TO RELATED APPLICATION  
         [0001]    This is a continuation application of PCT/MX00/00018 filed Apr. 3, 2000, which PCT application claims priority of Mexico Application number 993220 filed Apr. 7, 1999.  
         TECHNICAL FIELD  
         [0002]    The present invention relates to a trash dump that due to its special design is different from those already known, since it is more functional, more esthetic, safer, accessible and easily handled internally, as well as externally to the building where it is embedded.  
         BACKGROUND OF THE INVENTION  
         [0003]    Current trash dumps, do not solve the problem of containing the trash in a functional, esthetic and simultaneously, a hygienic way. One of the issues that is not satisfied by current dumps is the esthetic, since these are only an added object to the facade and not integrated to it. Likewise, they are not functional because they do not solve the problem of an inadequate containment of the wastes, and on the other hand, they are not either hygienic, since these dumps permit access to a great number of animals, such as rodents and insects. In view of the above, the trash dump with safety collector of this invention, solves the current problems for the handling of trash, since it is a trash dump which is embedded in a wall or gate and is accessible from outside by means of an opening in the wall and it has a collector which comprises a safety system of rotatory doors which permit:  
           [0004]    personnel of a trash collection service to pick up the trash disposed in the collector by opening a door without the need of entering the property, and even by means of some lock, if that is desired;  
           [0005]    the user can deposit the trash inside the dump, without leaving the building by opening some particular lock;  
           [0006]    people from outside cannot come into the building, even by entering in the trash dump.  
           [0007]    Likewise, since it is a dump which is kept hermetically closed, it will be free of animals and insects, impermeable and will not give off bad odors to the outside or within the building. In addition, it is durable because it is not subject to the inadequate handling and it will not obstruct the public way.  
         SUMMARY OF THE INVENTION  
         [0008]    The present invention refers to a trash dump which solves and satisfies the current needs, since such a dump can be embedded in the wall of a house, in the gate or in some other place enabling the people who live in the house can deposit the trash in the respective dump inside, instead of going out from the building, and the people in charge of the trash collection to pick up the trash from outside. This new trash dump has a safety doors system which allow the easy handling and make it safer, since it prevents the introduction into the house of the people who collect the trash.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0019]    Referring in detail to the drawings, and initially to FIGS. 1 and 2, they show a preferred embodiment of the trash dump with safety collector  10  according to this invention. It includes a section for the extraction of trash  1  which comprises a header with walls disposed in a truncated cone shape; a section for placing the trash which makes up the longitudinal part of the collector  10 ; a section for the introduction of the trash  3 , and a side section  4  for the access to the internal mechanism of the collector  10 .  
         [0020]    [0020]FIG. 3 shows a cross section cut of the front part of the trash dump  10 , which shows the parts that make up the internal doors system of the dump. This system is supported by an internal lid  5  and an external lid  15 , so that a support  11  is placed on the external face of the internal lid  5 , made of a metallic trip. All of the parts are joined by welding, so that it has a configuration with the shape of an inverted V (see FIGS. 4 through 8) and the support is joined to the peripheral part of the body  2  of the dump  10  (see FIG. 6).  
         [0021]    An axis  9  is disposed fixed to the top of each support  11  perpendicularly, so that the axis supports, and at the same time, allows the oscillatory movement of a first external door  6 , a rear door  7  and an internal door  8 .  
         [0022]    The actuation of the doors  7  and  8  is carried out by the mechanism located in the side parts of the trash dump, which are discussed below. The external door  6  has a convex shape having side walls, which are embedded in each of the axes  9 . The door is actuated said door by a handle  17  that is joined to the external face of the sides, so that the person collecting trash only moves the handle  17  upwardly to allow access to the inside of the dump, and moves the handle downwardly for closing the dump. For safety purposes, the door  6  has attached a pair of pivot springs  12  for causing self-closing of said door. The springs are supported by axes  9  so that one leg of the spring makes contact with the internal side face which includes the door  6  and the other leg of the spring  12  makes contact with the support means  11 .  
         [0023]    The bumper mean  28 , are also illustrated in FIG. 3. They comprise a pair of flanges of curved configuration, whose function is to prevent the external door  6  and the rear door  7  from being opened at the same time. The operation of the bumper mean is discussed below. A second support with an L-shape to support a bag of trash  14 , is disposed on the internal face of the internal side wall  5 . A drainage plug  16  is disposed at the bottom part of the trash dump  10 , to allow the leakage of fluids for the internal washing of the dump. A strap  18  coupled within the slot formed in the body of the dump is disposed at the top of the dump and serves as a stand for a safety lock (not shown).  
         [0024]    [0024]FIGS. 4 through 8 show the operation of doors  7  and  8 , which are located on each side of the trash dump  10 , as well as the internal mechanism of the dump. A part of the header  1 , shown with reference numeral  35 , is a part of the trash dump and it is useful to be assembled in an opening (not shown) within a wall. A mechanism for the actuation of doors  7  and  8  is shown, and FIG. 4 shows the trash dump  10  in a state without actuating. The mechanism is comprised basically of a pair of rods  21  and  22 . At the lower part, the rods join together to a first end of an actuating lever  20 , so that this lever is supported by a pedal support  30  which serves as the point of support. The actuating lever  20  is moved upwardly and downwardly in relation to the rods. The second end of the actuating lever  20  protrude from the dump  2  through a pair of slots  32  (see FIG. 6). A wide plate  19  is attached in the ends and it functions as an actuating pedal.  
         [0025]    Spring mean are adjacent to the pedal support  30 , wherein the spring  23  comprises a small resilient stem. One end of said stem is joined to the body of the pedal support  30  and the other end of the stem only makes contact with a bumper  33 . The bumper is joined to the external face of the side wall  5  by welding. The second spring  24  is placed at the top, next to the stem spring  23 , and this one operates as a bumper for the actuation lever, when a force is applied on the pedal  19 .  
         [0026]    One of the side walls of the internal door  8  is joined to the top of the bar  21  by a pin to permit the upward and downward movement of the door. The bar  22  is identified as a “stick” type bar that is joined to the external side wall of the door  7  by the second pin means, so that that door is also moved upwardly and downwardly.  
         [0027]    As mentioned before, FIG. 4 shows each of the doors when they are not actuated. FIG. 5 shows the raising of the door  6  but without actuating the doors mechanism. FIG. 6 shows the doors without actuating. The safety means  25  can also be seen, wherein the said safety means comprises a latch or lock placed over the flange  18  to prevent raising of the door  6 . This is accomplished by a key (not shown) which actuates the pin of the lock or latch. This pin penetrates in a hole (not shown) disposed at the top of the trash dump  10 , and prevents in this way the introduction of to the inside of the trash dump of strange people or simply the introduction of any object when nobody is inside the building. FIG. 7 shows the same FIG.  4 , but with the door  6  opened. One of the internal side circular walls of door  8  can also be seen with the head of axis  9 , which allows the oscillatory movement of same.  
         [0028]    [0028]FIG. 8 shows the actuation of doors  7  and  8  when the pedal  19  is pushed downward. This causes the actuating lever  20  joined to the pedal to move the bars  21  and  22  upwardly, to cause the rotatory movement of the doors over axis  9 , causing the door  7  to tend to turn clockwise and causing the circular walls of the internal door  8  to turn counter clockwise.  
         [0029]    Introducing the trash inside the dump  2  is done as follows. First, before actuating the pedal  19  downwardly, there is a radial sectional part  36  of door  8 , which serves as a support for the trash (see FIG. 3). This sectional part  36  is in an overlapped position at the same distance of the rear part of section  3  of the dump  20 . When pushing pedal  19 , the door  7  turns upstream and the radial section  36  of door  8  tends to go downstream, so that the spring  24  functions as a bumper for the turn limit of both doors. Then the radial section  36  is placed in a transverse position. In that moment, the user can place the trash over the same.  
         [0030]    Once the trash has been placed on the radial section  36  of door  8 , the user can stop applying force on the pedal  19 , which causes the return of the internal and rear doors, by the pushing action of the springs  23  and  24  over the actuating lever  20 . At that moment, the trash falls by gravity inside the bag for the collection of trash  14 .  
         [0031]    As mentioned above, the bumper means  28 , comprise a pair of flanges of curved configuration, which function as safety means. When an individual from outside wishes to get into the building, both the external door  6  and the rear door  7  must be actuated at the same time to provide a passage for entering the building. In order to prevent this, a pair of flanges  28  is disposed, one on each side of the internal side wall that forms part of door  6 . When both doors  7  and  6  are actuated at the same time, the stick type bars  22  make contact with the flanges  28 . This causes both doors to be opened only for a relatively short distance, and in this way, it is avoided any intrusion.  
         [0032]    As an example, in FIG. 9, the trash dump  10  is installed in a wall  37 . There the embedded header of the dump provides it a pleasant and hygienic appearance and avoids the entry of animals.  
         [0033]    Although the present invention has been described in relation to a particular embodiment thereof, many other variations and modifications and other uses will become apparent to those skilled in the art. It is preferred, therefore, that the present invention be limited to not by the specific disclosure herein, but only by the appended claims.
