Description

Precast concrete with tray built-in security

Object of the invention

Precast concrete with tray built-in security

Background of the invention

The present invention relates to a passenger compartment prefabricated and designed to accommodate a drawer or container in your interior, so that when it is lowered by means auxiliary inside the prefabricated, rest on the part top of the safety tray and closing. Similarly when the drawer or container is lifted vertically by means auxiliary, and completely removed from the interior of the prefabricated, the tray is on top of the drawer making the functions of safety tray and upper closing tray.

Currently the trays or platforms of security incorporate a structure or pillars on which slide the trays or platforms, being the main objective of the present invention eliminate said pillars and / or structure notably improving the leveling of the safety tray and preventing any blockage of it.

Description of the invention

Precast concrete with tray built-in security object of this registry, resolves the inconveniences mentioned above, also providing other additional advantages that will be apparent from the description which is accompanied below.

The present invention, simply and Explanatory, refers to a safety tray and closing with wheels, embedded between guides made with profiles preferably in the form of L, which are sausages or partially melted, preferably at the edges internal verticals of a precast concrete. In the part top of these guides or optionally at the top of the prefabricated, there are some pulleys that serve to slide steel cables, which in turn subject to counterweights and to the tray of security, acting the set like system of opening and closing automatically

It should be noted that the tray is guided for so many wheels in solidarity with the safety tray and closing as vertical edges have the prefabricated, which avoid the inclinations or lateral displacements of this same tray of security, providing permanent leveling and preventing any blockage, being a novelty and improvement with respect to existing systems.

The security tray system with the Precast concrete forms an indivisible set, generating a unit that differs from those known in the current state of the technique, which are separate sets consisting of a prefabricated and a metal structure that rests on the part top of the prefabricated by a frame or at the base of the same.

To complete the description below is going to be done and in order to help a better understanding of the Precast concrete with built-in safety tray, it accompanies the present specification, of a set of plans in whose figures, in an illustrative and non-limiting manner, are represented the most significant details of the invention.

Description of a preferred embodiment

In view of the aforementioned figures and according to the numbering adopted, a preferred but not limiting embodiment of the invention can be observed therein , which consists of a prefabricated concrete cabin (4) composed of four walls and a base or optional floor. Preferably in the inner corners formed by the walls of the prefabricated (4) there are embedded guides (3) composed of an L-shaped profile. In the upper part of these guides (4) and on one of its sides there are some lugs to accommodate a pulley (5) on which a steel cable (6) slides fixed at one of its ends to a counterweight (7), and at the other at a vertex or point near a vertex of a tray security (1). The two counterweights (7) are arranged in parallel between them and are adjacent to the two interior walls of the prefabricated. Seen in plan (Fig. 1), the outer perimeter of the safety tray (1) is housed and delimited internally by the inner distance between two counterweights (7) and the inner distance by the other two prefabricated walls (4) where Counterweights are not adjacent. Also, seen on the floor (Fig. 1), in the vertices of the safety tray (1), wheels (2) are arranged in solidarity with this same safety tray (1). When the safety tray is moved vertically, the wheels rotate and move vertically on the internal faces of the guides (3). Optionally, from the internal faces of the guides (3), ribs or projections can protrude (Fig. 6) to more efficiently fix the vertical trajectory of the wheels.

The precast concrete cabin (4) is designed to accommodate a drawer or container (8). When this container (8) is hoisted vertically by auxiliary means, and completely removed from the interior of the prefabricated (4), the tray safety (1) is located in the upper part of the passenger compartment of concrete (4), the functions of this safety tray (1) as upper closing tray (Fig. 2, Fig. 3, Fig. 4). This safety tray (1) is supported by force gravitational exercise of counterweights (7). For this tray safety (1) scroll vertically down, it would be it is necessary to exert a downward force on this same safety tray (1) that will compensate the force gravitational exerted by the sum of the weights of both counterweights (7). This safety and closing tray (1) performs the function of prevent the accidental fall of people, objects, etc. inside of the concrete cabin.

When the drawer or container (8), designed to be housed inside the prefabricated passenger compartment of concrete (4), is lowered by auxiliary means on the inside the prefabricated (4), this container (8) rests on the upper part of the safety tray and closure (1). This container (8) has a weight greater than the sum of the counterweights (7), so that the container (8) and the safety tray and closure (1) both descend in solidarity inside the cabin of concrete (4) channeled by the wheels (2) that roll on the guides (3). At the same time that the safety tray (1) descends in a vertical path, the counterweights (7) rise in a vertical path (Fig. 7).

In Fig. 8 and Fig. 9 the position in the one that the safety and closing tray (1) is in the part bottom of the precast concrete cabin (4) given the weight of the container (8), and the counterweights (7) are in its higher position given the weight of the container (8).

The details, the shapes, the dimensions and other accessory elements, as well as the materials used in the Manufacture of precast concrete with safety tray incorporated object of the invention may conveniently be replaced by others that are technically equivalent and not depart from the essentiality of the invention or the defined scope by the claims included below.
