DESCRIPTION

Closing device for boxes.

Technical sector

The present invention relates to a closing device for arches comprising a quadrangular frame intended to be fixed around an access hole to a casket, and a quadrangular cover disposed at a front end of a handle and at a rear end of fastening hinges to the corresponding end of the frame.

This device is applicable as a closing element in access boxes to various facilities and, in particular, to those boxes that do not require that said device be embedded in the ground and flush with it.

State of the prior art

Currently, several devices are known for closing enclosures and access to underground facilities, which have a quadrangular frame, intended to be embedded in the ground and that is flush with it; and of a hinged cover in the frame with the possibility of turning between an opening position and a closing position.

These devices are frequently installed in traffic lanes, so they must have high strength and resistance and are adequate to withstand the passage of trucks and heavy vehicles. Due to these conditions, both the lid and the frame are made of cast iron, and have a high weight, which makes the manual operation of the lid considerably difficult when opening and closing.

In this type of closing device, the door in the open position is practically placed vertically and supported on the inner contour of the frame, being maintained in said position by the weight of the door itself, which entails a risk that the lid can be accidentally closed. trapping the operator.

It is also worth mentioning that the assembly or replacement of these devices requires a work to be carried out on the contour of the box to embed the frame.

These inconveniences cause this type of closing devices to be especially heavy, expensive and difficult to install in those boxes that are not on sidewalks or traffic crossing areas and that do not require that the frame and the lid be embedded and flush with soil.

The technical problem that arises is the development of a closing device, especially indicated for a superimposed, and not recessed, assembly on the ground and that presents some characteristics oriented to solve the problematic exposed previously.

Explanation of the invention

The closing device for arches of the invention is of the type mentioned in the preamble of the first claim, comprising: a quadrangular frame intended to be fixed around a recess for access to the casket and a quadrangular cover that has an anterior end of a handle and at a rear end of fastening hinges to the corresponding end of the frame.

According to the invention this device comprises: a perimeter frame formed by metal profiles of section "L", welded at its ends, which have a vertical wing that defines the inner contour of the frame, and a horizontal wing that extends from the end bottom of the vertical wing towards the outside of the frame, forming a support surface of the frame on the ground, in a superimposed and non-recessed position.

Said horizontal wing of the frame is provided with holes for mounting floor fixing screws.

This device comprises a tear-iron sheet lid that has a lower weight than the function caps; and means limiting the rotation of the lid towards an opening position, in which said lid forms an angle greater than 90 degrees with the frame.

The hinges of rotation of the door are mounted externally with respect to the vertical wall of the frame and, in the opening position the door remains stable, held by the opening limiting means; There is no risk of accidental closure by trapping the operator.

The means that limit the rotation of the cover are mounted on the sides of the frame and the cover, and consist of chain sections and / or hydraulic cylinders.

According to the invention, the cover internally comprises, at its front end, a housing provided with a handle-carrying hatch and mounted by means of an axis with the possibility of turning between: an opening position in which said hatch protrudes from the plane of the lid and the handle is accessible from the outside, and a closing position in which said trapdoor is arranged flush with the lid, and the handle is arranged hidden and protected inside the box.

Brief description of the content of the drawings.

To complement the description that is being made and in order to facilitate the understanding of the features of the invention, a set of drawings is attached to the present specification in which, with an illustrative and non-limiting nature, the following has been represented:

- Figure 1 shows a perspective view of an example of embodiment of the closing device for arches, according to the invention, in the closed position.

- Figure 2 shows a perspective view of the closing device of the previous figure with the lid open and in which the limiting means of turning the lid towards the opening position, constituted by hydraulic cylinders, can be observed.

- Figures 3 and 4 show both perspective and profile views of a variant embodiment of the closure device of the previous figures, with the lid in the open position and in which the limiting means of the rotation of the lid are constituted by two chain sections joined the sides of the frame and the lid.

- Figure 5 shows a detail of a portion of the lid of Figures 3 and 4, seen from its inner face, and provided with the case and the axis of rotation of the hatch carrying the handle.

Detailed exposition of embodiments of the invention.

In figures 1 and 2 the device comprises a quadrangular frame (1) and a quadrangular cover (2), which has at its front end a handle (21) fixed on the outer face of the lid (2), and in its rear end of hinges (22) fastening to the corresponding end of the frame (1).

The frame (1) is formed by metal profiles of section in "L", welded at its ends and have a vertical wing (11) and a horizontal wing (12) that extends from the lower end of the vertical wing (11 ) towards the outside of the frame (1), and is provided with holes (13) for mounting screws (not shown) for fixing to the ground.

The cover (1) is made of tear-iron sheet, which is non-slip to prevent slipping of the operators or passers-by and which has a greater resistance to bending than the smooth sheet.

In this embodiment, the limiting means for turning the lid towards the opening position are constituted by hydraulic cylinders (31) mounted on the sides of the frame (1) and the cover (2).

In the opening position, the cover (2) forms with the frame (1) an angle greater than 90 degrees, in order to guarantee its stability in said opening position and prevent it from being accidentally closed.

In the variant of embodiment shown in Figures 3 and 4, the device has a general structure analogous to that of Figures 1 and 2, presenting variations in what refers to the means that limit the rotation of the lid (2) and the handle (twenty-one).

Specifically in the embodiment of Figures 3 and 4, the means for limiting the rotation of the cover are constituted by chain sections (32) fixed at their ends to the sides of the frame (1) and the cover (2).

As can be seen in figures 4 and 5, the cover (2) internally comprises a box (23) provided with a trapdoor (25) carrying the handle (21) and mounted on a shaft (24) with the possibility of turning between: a closing position shown in figure 3, in which it is arranged flush with the cover (21) closing the box (23), and with the handle (21) inside the box (23); and an opening position, represented in figures 4 and 5, in which the handle (21) is accessible from the outside.

Once the nature of the invention has been sufficiently described, as well as an example of a preferred embodiment, it is stated to the appropriate effects that the materials, shape, size and arrangement of the described elements may be modified, provided that this does not imply alteration of the essential features of the invention that are claimed below.
