Description

Manhole cover.

Object of the invention

The present invention relates to a cover of record, of the type used to close an opening of access through a pavement.

Background of the invention

Nowadays it is common to use caps registration to be able to access through the pavement or floor to sewers, underground service galleries and arches for different uses

These caps are mainly made up of a surrounding frame intended to be fixed immovably to a access opening through a pavement, presenting said I frame an interior perimeter seat, and a lid properly said, of flat configuration and external contour coinciding with the said frame seat for tight fitting, leaving the top of the lid and the top edge of the flush frame with the surrounding pavement and being in said cover some means of extraction from outside, by means of which Remove the lid and you can access the casket, gallery or registry.

Most of these tapas present mainly sealing problems, allowing the passage of odors, liquids, insects and vapors, besides they result visually unsightly.

For example, in some cases the means of extraction are made up of holes made in the cover and in which it is possible to insert a hook to extract said cover. These holes allow odors to pass freely, vapors, liquids or insects, both from the underground hollow towards the surface as the other way around.

In other cases the hook is incorporated into the lid in the form of a folding or retractable handle, for example, arranged through through holes, and that can be removed partially, allowing to remove the lid, however this handle it is very visible on the surface of the lid being unsightly, although the cover is of the type of camouflages with a finish pavement on its surface.

To get a better seal, certain covers comprise a double or triple seal, but the outer cover is secured by a plurality of screws in the corners, and that require time for opening and closing, plus they look considerably.

Description of the invention

The registration cover, object of this invention, it presents some technical peculiarities destined to offer a tightness due to the passage of odors, vapors, insects and liquids, offering an optimal and concealed aesthetic appearance in the pavement, and with great ease of opening.

According to the invention, the registration cover that it comprises a surrounding frame with an interior perimeter seat, and a cap itself, flat and contour configuration exterior coinciding with the aforementioned frame seat for your tight coupling, essentially presents means of cover removal configured by a hollow cylindrical body, internally threaded, and closed by its lower end and a screw superiorly coupled to said hollow cylindrical body, said screw remaining in an inoperative position introduced in the hollow cylindrical body and its head is flush with the surface top of the lid. In turn, in an operational position of opening said cover, said screw head is partially extracted by unscrewing with a tool, for gripping and removal of the lid, for example by pulling with tongs or Similary.

In this way it is achieved that the lid does not present holes or openings that may constitute a step of smells and liquids

To get a better seal, in a embodiment the frame seat comprises a material gasket elastic for sealing the space between the top cover and said frame. The weight of the lid makes said gasket fit and adapt tightly, completing a perimeter seal between cover and frame.

In one embodiment, the screw head is conical with an alien coupling that makes it reduced to the eye, due to its circular and non-protruding contour, and is easily unscrewable by means of an alien tool for its
has been.

In order to get a finish the most concealed possible, the lid is configured in flat iron with vertical side walls, defining an upper gap filled with a continuation fill of the surrounding pavement, for example the tiles or other finishing materials used on said pavement. Inside the lid hole is the hollow cylindrical body for screw coupling, whose head is flush superiorly with said filling of continuation. This continuous pavement filling allows for one side reduce the visual impact of the lid and have its weight set the cover against the frame seat. So from the lid you can only see the fine upper edges and the central gripping screw, creating An authentic continuity of the pavement.

In an alternative embodiment, a handle with an interchangeable threaded section with the screw in the operative position for the removal of the lid, thereby facilitates said removal by replacing said screw with the handle.

Description of the figures

To complement the description that is being performing and in order to facilitate the understanding of characteristics of the invention, is attached herein descriptive a set of drawings in which, for illustrative purposes and not limiting, the following has been represented:

- Figure 1 shows a sectional view transversely of a registration cover installed in the pavement.

- Figure 2 shows a plan view of the manhole cover.

- Figure 3 shows an elevation view sectioning of the exploding log cover.

- Figure 4 shows a screw detail completely inserted into the lid and flush with its surface higher.

- Figure 5 shows a screw detail partially removed for gripping by means of a tool for the subsequent removal of the lid.

- Figure 6 shows a detail of the handle coupling that replaces the screw for the cover removal.

Preferred Embodiment of the Invention

As can be seen in the figures referenced, the registration cover comprises a frame (1) attachable to the opening of an access through a pavement (2) and a cover (3) proper, of closing said opening by snapping into the frame (1), said frame (1) and the top cover (3) remaining flush with the surrounding pavement (2) to provide the continuity of said pavement (2) and the blocking of odors and liquids through the opening. The framework (1), is constituted in a resistant metallic material, and is rectangular in shape, presenting an interior seat (11) extended internally around the access opening, being on said seat (11) a flat gasket (4) of elastic material. The lid (3) upper is configured in a flat piece, rectangular in shape and which in its outline has vertical walls (31) prolonged defining a hole (32) for filling placement continuation (21) with the surrounding pavement (2), keeping its continuity The cover (3) has extraction means in its upper part, configured by a hollow cylindrical body (33) internally threaded, welded to said cover (3) in its upper face and embedded in the continuation material (21), presenting its lower end (34) closed, being coupled in the  open top end of this hollow cylindrical body a screw (5) with a conical shaped head (51) and with coupling alien, so that in an inoperative position said head (51) of the screw (5) is flush with the continuation filler (21) of the cover (2) without protruding, and that in an operative position, by means of an alien key it is partially outgoing of the hollow cylindrical body (33) threaded, on the level of the filling of continuity (21) to facilitate the removal of the lid (3) using a tool (H), such as pincers, as well represented in figure 5.

In one embodiment, depicted in Figure 6, the screw (5) is replaced by a handle (6) with a section Threaded (61) interchangeable.

Once nature is sufficiently described of the invention, as well as a preferred embodiment, for the appropriate purposes that the materials, form, size and arrangement of the elements described may be modified, as long as this does not imply an alteration of the essential features of the invention claimed in continuation.
