Abstract

Container Security System underground, consisting of a protector / cover (2) of geometry conjugated with the mouth of the pit / chest (1) where it is kept hidden while the underground system is closed and in the position of deposit waste; means of action (3) to swing the protector (2) around its articulation (2) between two positions extreme; and retention means (4) with lock (5) to hold the protector / cover (2) in operational position, when the system underground is open and in position to lift the container (D), to collect waste and / or to clean / disinfect it.

Description

Container Security System buried.

The present invention introduces a system of protection / safety in underground container tanks of employees, for example, for the collection of urban solids (RSU)

It is about avoiding accidental falls by inside the underground tank when holding the casket open (for example, to perform the work of collecting waste or cleaning / disinfection of the receptacle).

The underground systems of garbage deposit to collect waste in towns where, the underground container is hidden, a mailbox emerging from view which allows access to the interior to deposit waste.

In all the systems of this type that form part of the current state of the art, there is a problem not Security resolved: When the system is open, to collect waste and / or to clean / disinfect the underground receptacle accidental falls can occur inside the pit / chest.

The object of the invention is a security system which is characterized because it consists of:

a) a conjugate geometry protector / cover with the mouth of the box where it is arranged articulated to one of its Interior walls;

b) means of action to swing the protector / cover around its articulation between two positions extreme;

c) retention means with locking to hold to the protector / cover in operative position;

so that, as long as the mouth of the casket, said protector / cover is held down and hidden inside the pit but when opened and hoisted the container, the protector / cover is closing the mouth under the container until be fully deployed and locked by closing your mouth to avoid accidental falls inside the pit / chest while Stay open

From this general conception, they are any embodiments included in the object of the invention practices that do not alter, change or modify essentiality proposal. In particular, it is indistinct for the purposes of this invention:

a) that the protector / cover is a cover of one or several pieces; rigid or flexible; mesh, framed or not; or sheets) of any other type;

b) that the means of action, to open / close the protector / cover are fluid acting, mechanical or electromechanical;

c) that the means to position and retain the protector / cover in operating position have simple structure or double, as well as available, relating the protector / cover with any of the inner walls of the casket;

d) that the unlocking element of said positioning / retaining means is arranged in the protector / cover
ra, in the environment of the box or in the element itself; as well as being operated by the container itself, by the operator or by any external actuator (for example a remote control).

Figure 2 represents a side view schematic similar to figure 1 in three phases: with protector / cover (2) folded -figure 2a-, semi-deployed -figure 2b- and operational -figure 2 C-.

Figure 3 represents a side view schematic similar to figure 2b where the retention means they have an alternative configuration (4b) with lock (5).

Figure 4 represents a side view schematic similar to figure 3 where the means of action (3) they have an alternative configuration (with torsion spring replacing the cylinder).

An example of practical, non-limiting embodiment of the present invention.

The present invention concerns a system of security for underground containers of collection of MSW, of the which incorporates a waste receiving mailbox arranged on a pit / casket (1) housing the underground container (D).

The casket (1) is an underground cavity, in the that the container (D) is available with the possibility of extracting it for collect waste and / or to clean / disinfect both the container (D) as to the pit / chest (1).

In accordance with the invention, and according to the represented embodiment -see figure 1- the recommended system consists of

-

a protector / cover (2),

-

media acting (3),

-

media retention (4) with lock (5), and

-

media stop (6), travel limiters.

       \ vskip1.000000 \ baselineskip
    

The protector / cover (2) is articulated in (21) to one of the interior walls (11) of the casket (1).

The means (4) retain the protector / cover (2) in operational position and keep it locked in this position while not voluntarily unlocked by the media (5) (either manually or automatically).

The stop means (6) establish the end of opening of the protector / cover (2), limiting it to the horizontal position, in which the protector (2) occludes the casket (1) -see figure 2c-.

They are included in the object of the invention any practical realizations that do not distort this basic conception Several examples of realization based on the basic configuration described:

Example 1

-See Figure 2 C-

In this exemplary embodiment the means of actuation (3) are fluidic cylinders with their sleeve and piston attached articulated to the inner wall (11) of the casket (1) and to the protector / cover (2) on its inner face.

The locking means (4) are one or several posts (4a) articulated in (41) to the inner wall opposite (12) of the case (1) in such a way that in position operational, the post body exceeds the vertical plane of the wall (12) reaching and maintaining a stable position that supports the protector / cover (2) and that is not abandoned until provoked an unlocked (5a) manually or automatically actuated with the container descent (D).

Example 2

-See Figure 3-

In this exemplary embodiment the means of acting (3) are also fluid cylinders similar to those described for the previous embodiment example.

The locking means (4) are Now, at least one double scissors (4b) with three arms, two of them articulated with each other in (40) and respectively articulated one in (41) to the inner wall (11) of the casket (1) and the other in (42) to own protector / cover (2), going the third articulated arm to this one in (43) and with its end emerging through the protector / cover (2) to act as an unlocking element (5) when manipulated from the outside (manually or automatically).

Example 3

-See Figure 4-

In this exemplary embodiment the means of actuation (3) are mechanically functioning (for example counterweights or, preferably, a torsion spring (3a).

The locking means (4) are, at less, a latch mechanism (4c) that locks / unlocks by lever (5c) associated with it.

With this basic structuring and any of the structuring of the examples described in the object system of the invention:

a) while the collection system is operational, that is, it is closing the mouth of the casket (1), the protector / cover (2) is kept down and hidden inside the casket (1) attached to one of its interior walls (11);

b) when opening the system and lifting the container (D) the protector / cover (2) is closing the mouth under the container (D) until it is fully deployed - and locked - closing the mouth of the case (1) to prevent accidental falls to your inside as long as the system is kept open, to download the container (D) or for cleaning / disinfection.
