Description

Internal elastic cover, recordable and adaptable for sealing odors and gas leaks in boxes, wells and tanks.

OBJECT OF THE INVENTION

The present invention, as expressed in the statement of this specification, is intended to provide an elastic canvas with wide edges of rubber or similar material mounted on a structure (for example metallic or plastic) extensible light and of variable geometry, which allows to adapt the edges of said canvas to the geometry of the shape of the interior of the casket, well or deposit, sealing it until guaranteeing the complete seal against odors, with the possibility of removing the seal with ease and reusing it as many times as desired.

The present invention finds its field of application in construction and industry in general, in particular in the plumbing and sanitation sector of buildings, courtyards, exterior and interior inhabited rolling and passage areas.

BACKGROUND IN THE STATE OF THE TECHNIQUE

The state of the art in the field, provides a wide variety of boxes and wells commonly used for the collection and / or conduction of wastewater and for its evacuation to other collectors, boxes and wells. Likewise, it is also common for deposits that need a registrable seal to prevent gases from escaping from the inside to the outside through its lid.

Usually, this type of casings, wells and even deposits incorporate a cover in its upper base of reinforced concrete, cast iron, PVC, or other similar, which, being necessarily recordable, does not guarantee adequate sealing that prevents the penetration of odors from the Inland outward inhabited. It is important that it is recordable, if possible in a simple way,

allowing access to its interior when you have to unclog any element,

clean it or perform similar actions.

On the other hand, the boxes or wells that have hydraulic siphons inside, end up suffering from obstruction problems due, precisely, to the mechanism of these siphons. In these cases, to ensure that water flows, it is common for users to tend to eliminate the siphons despite the problems of odors and health that such elimination entails.

When the escape of gases and the bad smell occurs in an inhabited, public enclosure

or private, the inconvenience and unhealthiness can be considerable, especially if users are more or less permanently present in the enclosure. In these situations, when professionals in charge of maintenance and repair of these elements attend, they immediately choose to eliminate the internal siphon and try to seal the lid, which does not guarantee that odors or gas leakage occur due to the nature of the caps that are currently use, and at the same time the possibility of continuing to make the casket or well easily registered, which would not be necessary with the proposed invention is eliminated.

From the investigation of documents, bibliographies or inventions that reflect the state of the art on the subject, several related inventions have been detected, although none of the nature and properties of the one proposed with this, among which we highlight the following:

The invention ES1010714U "Cover for boxes", has the disadvantage of being always attached to the box, being neither adaptable nor waterproof. In addition, the proposed lid requires a casket with specific parts.

EXPLANATION OF THE INVENTION

By way of explanation of the invention, the 'internal elastic, recordable and adaptable lid for sealing odor and gas leaks in arches, wells and tanks' is formed according to a rectangular or circular elastic canvas depending on the shape of the mouth of the well or casket on which it is to be installed, provided with an elastic band also based on rubber or synthetic rubber of adequate thickness, which is shaped in geometry and stiffness based on the thrust of metal profiles that contact the perimeter inside of the referred band.

5 These profiles make up a rectangular or polygonal plan, if any, of variable size based on the fact that each profile is extensible by means of the relative displacement between the two elements that compose it, through the corresponding sets of grooves and pins.

10On the same time, the ends of the aforementioned perimeter profiles, are connected by eight other profiles for rectangular covers - six or twelve or more in the case of circular covers -, also extendable as a telescopic arm, which start from the vertices and midpoints on each side of the rectangle in the case of rectangular plants and the vertices of the regular polygon in the case of circular cover 15 as a radius, which are located in the center of the plant, where there is a central cylindrical axis perpendicular to the plane of said plant to which they are welded. From said axis, and at a certain height with respect to the floor plan described above, a washer is disposed from which flexible rods that extend to form an articulated knot in the outer part of each of

20 the eight, six or twelve radial and extensible profiles.

Finally, to ensure proper sealing, the upper part of the central vertical axis has a thread with a nut-type insert, which when screwed exerts pressure on the washer from which the rods start, causing them

25 push the corresponding radial profiles and, in turn, these to the profiles that make up the circular, rectangular or polygonal base, forcing to adapt the geometry of the perimeter elastic band, to the geometry of the sides of the casket, well or deposit, and with this also that of the elastic canvas, resulting in a completely sealed mouth.

EXAMPLE OF PREFERRED EMBODIMENT

By way of example of a preferred embodiment of the "internal elastic cover, recordable and adaptable for sealing odors and gas leaks in caskets, wells and tanks" and in view of the figures, it can be seen how it is carried out in base to a piece of elastic canvas (1) rectangular or circular (Figure 1 and Figure 9, respectively), depending on the shape of the mouth of the well or casket on which it is mounted, with termination in a perimeter elastic band based of rubber or synthetic rubber (2) five centimeters thick, which is shaped and stiffened by perimeter and extensible metal profiles (3) in contact with the inner face of said band. The said perimetral and extensible metal profiles (3), form a rectangular or polygonal plan, where appropriate, of variable geometry when crimped by means of grooves and pin screws (11) that provide the desired length to the rubber-based perimetral elastic band or synthetic rubber (2). In turn, these perimeter metal profiles and

extensible (3), are connected to other radial and extensible metal profiles

(4) arranged in an amount adapted to the configuration of the lid as seen in Figure 1 and Figure 9, with termination in the center of said lid, where a central cylindrical axis (5), perpendicular, is arranged to the plane of bliss

5 floor to which they are welded.

In the aforementioned central cylindrical axis (5) and at a certain height with respect to the floor plan described above, a washer (6) is inserted from which flexible rods (7) start, which at its other end are inserted by means of articulated knots (8) 10 on the outside of each of the radial and extensible metal profiles (4). The upper part of the central cylindrical shaft (5) has a thread (9) with a nut type (10), threaded, which, when screwed, exerts pressure on the washer

(6) from which the rods split causing them to push the radial and extensible metal profiles (4) and, in turn, these to the perimeter metal profiles and

15 extensible (3) forcing to adapt the geometry of the elastic band of rubber, rubber or similar material (2), to the geometry of the sides of the casket, well or deposit, which makes the elastic canvas (1) also adapt its geometry until completely sealed.

It is not considered necessary to make this description more extensive so that any person skilled in the art understands the scope of the invention and the advantages derived therefrom. The elements that compose it, shapes, dimensions, materials or connection techniques, will be susceptible of variation as long as this does not imply an alteration in the essentiality of the invention.
