ROAD DEVICE

The present invention relates to a road device comprising a frame and a cover or a grid to cover at least part of the frame, or the sealing is not compulsory.

A known problem with such devices is to ensure the compatibility of the seats, and to avoid the accumulation of dirt on the seats between the cover or the grid and the frame, to facilitate opening and closing.

The objective of the invention is to provide such a device in which these problems are resolved.

According to the invention, this objective is achieved with a road system comprising a frame, a cover or a grid to cover at least part of the frame, and several studs which are arranged distributed over the inner periphery of the frame and projecting from on the inside surface of the frame, to support the cover or the grid.

With such studs, the frame no longer requires a flange to support the cover or the grid. Such studs prevent the accumulation of dirt on the seats between the cover or the grid and the frame, thanks to their low contact with the cover or the grid and the fact that they are released by forming protrusions.

The pads are preferably made of elastic material.

Thus, with very little elastic material, they can reduce the noise caused by the clacking of the cover or the grid on the frame during the passage of vehicles. Their small surface also allows a deformation which absorbs the flatness defects of the grid or of the cover and of the frame.

A solution with such pads no longer requires machining on the grid / cover and frame.

BE2016 / 5969

The studs can more specifically be made of an elastomer. Preferably they are then made of EPDM (ethylene-propylene-diene monomer). Alternatively, they can for example be made of SBR (styrene-butadiene rubber), CR (chloroprene rubber) or NBR (butadiene-acrylonitrile rubber).

A particular variant embodiment of the device according to the invention comprises housings arranged distributed over the inner periphery of the frame and projecting relative to the inner surface of the frame, to accommodate the studs for arranging them.

These housings are preferably made in one piece with the frame.

The pads are preferably glued in the corresponding housings, this preferably with an EPDM glue which has two functions, i.e. bonding proper and blocking any play due to the manufacturing tolerances of the elastomeric pads.

The studs are in a preferred embodiment in the form of a dovetail, to increase their retention.

The frame is preferably made of cast iron. The cover or grid can also be made of cast iron.

In a more specific embodiment, the cover or the grid can be pivoted by a first edge on a corresponding edge of the frame.

Even more specific, the cover or the grid may comprise an elastic bar with a second edge, opposite the first edge, for locking the grid or the cover to the frame with a system for locking by such an elastic bar.

A device according to the invention can more specifically be a drain.

BE2016 / 5969

The present invention will now be explained in more detail by describing an embodiment of a device according to the invention. This description is only intended to provide an illustrative example of the invention and to reveal other advantages and details of the devices according to the invention, and it should in no case be interpreted as a limitation of the field of use of the invention. invention or patent rights claimed in claims.

In this detailed description, the reference numerals refer to the appended drawings, in which:

Figure 1 shows a drain according to the invention in perspective with its grid in its open position;

Figure 2 shows the chute of Figure 1 in perspective with its grid in its closed position;

Figure 3 shows a perspective detail of Figure 1 at a housing and a pad;

Figure 4 shows the housing and the pad of Figure 3 separately in perspective.

In the figures, an embodiment of a drain (1) according to the invention is shown.

This drain (1) comprises a frame (2) and a grid (3) which is mounted on the frame (2) in a pivoting manner. The grid (3) can then pivot between a closed position (see Figure 2) and an open position (see Figure 1).

The frame (2) and the grid (3) are made of cast iron.

Housing (5) (see Figure 4) are made in one piece with the frame (2) and are arranged distributed on the inner periphery of the frame (2) and projecting from the inner surface of the frame (2) (see Figure 1).

EPDM studs (4) (see FIG. 4) are glued in these housings (5) with an EPDM adhesive (see FIGS. 1 and 3). These studs (4) have a tail shape

BE2016 / 5969 dovetail and the housings (5) have a correspondingly shaped recess to accommodate these studs (4).

In the closed position of the grid (3), the grid (3) rests on the studs (4).

The drain (1) can easily be opened and closed by road cleaning teams.

Thanks to the EPDM studs (4), noises caused by the slamming of the grid on the tank, during the passage of the vehicles, are reduced with little EPDM material.

The small contact surface between the grid (3) and the studs (4) allows an ideal adjustment and prevents dirt from accumulating on these same surfaces.

These studs (4) and their housings (5) no longer require machining on the grid (3).
