DESCRIPTION

Non-slip safety element for the covers and grids of caskets and manholes.

OBJECT OF THE INVENTION

The present invention aims to guarantee the road safety of pedestrians and vehicles, for areas of pedestrian and vehicular traffic on the covers and grilles of arches and manholes.

The use of our invention is also contemplated in the covers and grids of boxes and manholes as a novel publicity element on public roads, showing slogans, texts or any claim message in advertising (inserted into the security element itself) , thus providing our invention with added value.

Also included in our element of citizen awareness message security, in relation to road safety, both for pedestrians and drivers.

SECTOR OF THE TECHNIQUE

The present invention relates to a non-slip safety element applicable to the mobile elements (covers and grilles) of the covering and closing devices of manholes and manholes for circulation areas used by pedestrians and vehicles.

Our invention has its field of application in the field of road safety for traffic areas used by pedestrians and vehicles, since it prevents possible accidents to pedestrians and users of two, three and four wheel vehicles that circulate on the covers and grilles metal boxes and manholes.

This element turns out to be an active safety system with non-slip power, guaranteeing a road safety situation of said devices for both pedestrians and vehicle drivers, and in the latter case in particular for those traveling on public roads on motorcycles or bicycles.

At present, the use of covers and grilles is known as mobile covering and closing devices for the manholes and manholes, being located on all public roads, both for traffic areas used by pedestrians and vehicles.

The existence of these devices on public roads is a potential and real danger of minor and / or major accidents for users who travel through the traffic areas authorized for pedestrians and vehicles.

The real problem of road safety of the covers and grilles of the cabs and manholes is due to the use as a manufacturing material for cast iron and coating with paints, which in meteorological conditions of precipitation in the form of any type of rain are totally sliding, as well as with frost, cleaning of public roads with water, spills of chemical products and oils, etc. ..

The incorporation of these devices, mainly on public roads, causes a considerable decrease in the friction coefficient granted by the metal surface against the asphalt.

At present there is no effective action regarding improving Road Safety for both pedestrians and vehicle users who must circulate on public roads every day where these covering and closing devices abound.

Although some (cast) caps of caskets and manholes are engraved / embossed on their surface, they are not made with any abrasive material, but with cast iron, and therefore in no case can they be considered effective in preventing slips and falls , since the coefficient of friction they offer is much lower than that of asphalt (considered as a reference element to evaluate the anti-slip capacity), being 0.35 for wet surfaces, and therefore lower than the value of 0.45 which is the minimum acceptable value for Consider a non-slip surface.

To this we must add the fact that being finished with foundry material they are not

valid for ice and snow conditions and are not effective with grease and oily stains, and on the other hand the fact that they are not insulating from electricity, with the consequent danger for the operators, and even for the transit of pets to through the covers and grilles.

Review that at present there are covers and grilles made of a polymeric material, but the high manufacturing costs of these devices, as well as sometimes the low performance in load support and vehicular traffic, make their introduction into the market less viable. , and of course in no case are non-slip surfaces.

The introduction of polymeric materials in the manufacture of caps for caskets and manholes only obey anti-theft solutions of cast iron lids, light weight in maintenance and aesthetic tasks, without solving the potential danger of slips and falls for pedestrians and motorcycle and bicycle drivers in slippery situations due to rain, oil and grease spills, frost.

We cite the following documents found as a reflection of the state of the art in this regard:

Thus, document ES2537023B1, Cover and registration frame, made of glass fiber reinforced plastic, and manufacturing procedure. Describes the use of covers made of polymeric material, but in no case has a non-slip surface, so it does not improve what is proposed in The present invention.

On the other hand, document ES2179788B1 describes a cover for registration boxes that has a quadrangular surface, preferably with a non-slip surface on its upper part, holes for fixing screws to a base, a dirt penetration protection skirt, and a set of ribs, converging towards a central nucleus.

The lid will be made from a fiber reinforced thermoplastic material.

However, the introduction of an abrasive material is not mentioned anywhere

that grants a coefficient of friction similar to asphalt, nor is the roughness of said surface specified.

In both written documents they refer to the manufacture and design of arbor covers made from a polymeric material reinforced with fiberglass, but in no case does it propose as an object of the invention the innovation of a totally non-slip surface, made evident by the provide technical data of the coefficient of friction values (in the description of the invention), and in any case proposes the manufacture of new models of registration covers.

Regarding the use of the covers of boxes and manholes as advertising media (by incorporating our non-slip safety element to them), there is no document that proves the existence of any invention for this use, thus providing our I invent an innovative advertising system on public roads, whether in areas of pedestrian and / or vehicular traffic.

All this advertising claim on public or private roads, would be carried out fully guaranteeing road safety, due to the high anti-slip power and fixation to the substrate that our invention presents.

Therefore, as can be seen from the research carried out, none of the documents found affect the novelty and inventiveness of our invention, since the object of our invention in any case is the incorporation of a safety element with a non-slip effect. the covers of cabs and manholes in use (with mostly foundry material) and its use when required as an advertising element.

In order to remedy the existing deficiency with respect to the road safety of the mobile elements in the covering and closing devices in caskets and manholes, the invention proposes a safety element with anti-slip effect, applicable by coating on the covers and grilles of smelting, regardless of the type of manufacturing material (molded or rolled steel, lamellar and spheroidal graphite cast iron), geometry (round, rectangular ...) of such devices, and the location of said lids and grilles (well on sidewalks for pedestrians or public roads of vehicle circulation), being applicable for any kind of cover and grid according to the UNE EN ISO 124 standard.

This non-slip safety element will be applied to the covers and grilles by means of mechanical fastening with screws or bolts, and / or by chemical fixation.

This non-slip safety element is considered as active road safety, since it prevents and eliminates accidents caused by slips, falls or skidding, anticipating in this way the possibility of carrying out such accidents.

The advantage of the incorporation of this element of second the covers and grids already installed, lies mainly in the fact of considerably improving the grip, since it is a material with a friction coefficient similar to that of asphalt, being ideal for installation on irregular surfaces and of steel, and of easy installation on the covers and grilles, which reduces costs, and can also be used immediately after being placed.

Specifically, our non-slip safety element is a synthetic material with a high quality polymer matrix (specifically thermosetting or thermoplastic polymers), to which different additives and / or fillers are added, and reinforcing elements (fibers) creating a surface Non-slip very effective and durable.

This rugged, non-slip surface finish provides a safe and effective solution for the slippery surfaces of cast iron lids and grids.

The mechanical properties of our element are provided by the reinforcement material, while the compaction, shape and weather resistance depend on the matrix.

And more importantly, the anti-slip power is given by the presence of a combination of abrasive particles (mineral fillers), fully adhered to the matrix, and being an integral part of the safety element.

As a general aspect, we can consider that our non-slip safety element has the following properties:

- Tensile strength - Compressive strength - Flexural strength

-Coefficient of thermal expansion: minimum shrinkage and expansion characteristics, that is, the material will not bend or deform when exposed to high temperatures.

- Surface roughness and coefficient of friction: wet pendulum P. values greater than 35 (low slip potential), and roughness values greater than 50 Rz.

Our safety element will be applied (as a coating) directly on the covers and grilles, either in those currently in use and in situ (on public roads), or by joining the manufacturing process of new covers (prior to installation and start-up of covers and grilles on public roads), allows to take advantage of the use of the current foundry closing and covering devices (without therefore having to be replaced), as well as using the benefits of cast iron material from which They are manufactured, providing our element with a non-slip effect that currently covers and grids are devoid of.

1. Minimal maintenance (it will not degrade or corrode), acting at the same time as an anti-corrosion protective element for cast iron in the cover of the arches, being ideal for use in marine and saline environments.

2. High impact resistance (enhancing in itself the characteristics of cast iron with respect to this aspect) and flexibility resistance.

3. Long durability, virtually indestructible, totally fragmentation proof and resistant to severe conditions.

4. Very suitable in ice and snow conditions

5. Effective anti-slip power in wet, oily conditions, spills, etc., totally reducing the risk of falls and slips.

6. Minimal expansion and contraction and will not yield or deform under extreme temperatures.

7. Non-conductive (electricity insulator), especially of great importance for maintenance work carried out by operators

8. Considerable reduction in noise pollution caused by vehicular traffic on the covers of the boxes.

9. Deterrent for the "thieves" of cast iron caps.

10. Recyclable element, which could be introduced again in the production cycle.

With little maintenance, our security element will retain its active anti-slip properties for a long period of time, depending on the application.

In addition, due to the high level UV protection layer (gel coat), it will not suffer from significant color degradation.

In conclusion, the present invention has as its object the incorporation by coating of a non-slip surface in the covers and grids of cast iron of caskets and manholes currently in use, or said safety element would be incorporated into the newly manufactured ones in the production process.

At older, it can be affirmed that the load bearing and impact resistance properties of cast iron from which the casing tops are made would look

Thus, when the metal covers of the manholes and manholes suffer the continuous action of heavy vehicles, material breaks occur that, in addition to being extremely dangerous for passers-by, have the potential problem of increasing the risk of electrical contact, This would be considerably avoided by applying our security element to the metal covers.

And finally comment that our element will act as a protective agent against atmospheric corrosion, and as a protective barrier for chemical agents that could attack the cast iron material, thus contributing an Added Value, by favoring mechanical resistance in the long run. of the covers.

DESCRPTION OF A PREFERRED EMBODIMENT OF THE INVENTION

A preferred embodiment of the proposed invention consists in the lining of the covers (3) and grids (4) of casting of the cabs and manholes, by means of our safety element (2), located in the areas of circulation of vehicles on public roads (6).

When this non-slip safety element (2) is used as a cover for the metal surface of the lid (3) of the archery or manhole, it will have satisfactory adhesion with the casting material (thus complying with the technical specifications of the UNE EN standard 124), and thus it will be possible to thus grant the surface of the lid a totally non-slip effect, which it lacks without said element.

In order to achieve a perfect adhesion of our safety element (2) with the corresponding metal surface of the cover (3), it will be ensured that the area to be covered is clean, dry and free of grease, dust and dissolved particles, or any interface between the substrate (3) and the non-slip element (2).

A blasting with sand or with water pressure is recommended for the preparation of the support (3), and can sometimes be replaced by a mechanical or manual brushing with a metal spike.

For the lining of the cover (3) of the casket, we will take into account at least the surface of cast iron that configures said cover (3), and the coating with our element (2) of the frame (8) (fixed element being optional) of the covering or closing device) of the case.

The design of this procedure will allow the covers (2) or grilles (4) to be opened by means of normal use tools, that is, the holes (1) or holes in the covers (3) would be left uncovered. the opening operations of these, leaving such opening devices (1) always free of the coating.

For fixing our safety element (2) non-slip to the covers (3) of the cabs and manholes, mechanical anchoring will be used by

5

35

bolts / screws (5) (ex: 4-5 mm x 30 mm self-tapping screws with flat star head) of ductile cast iron and expansion plugs, which allow an optimal anchorage to the surface during its useful life and the eventual elimination of the same, which will be anchored to the ferrous material of the lid (3), and as an additional measure, when the situation requires it, the application of welding points to said bolts / screws (5), or application of an adhesive "Fixer" of screws.

It is recommended, whenever possible, for mechanical fixing, the application of a sealant adhesive or an elastomer sealant, thus neutralizing the possible gap between our safety element and the surface on which it is installed.

The application of this adhesive will be carried out by means of a cartridge gun, or with the help of a spatula or trowel generally.

Our sealing has the great advantage that it has great adhesion without primer, suitable for contact with water, very good weather and UV resistance, valid for all types of thicknesses, and excellent chemical resistance to detergents, grease, water, etc. the ice-thaw cycles.

. For those covers (3) of boxes that have surface reliefs, these may be overcome by applying a thicker putty cord, where necessary.

For mechanical fastening, excessive tightening will be avoided, and holes must be drilled with adequate clearance.

It is important that the position of the screw (5) inside the hole is perpendicular to the substrate, to ensure the correct distribution of stresses throughout the element, as well as the fact that the screws (5) will be fully embedded in the cover (3) , without there being superficial highlights of these (5).

Also, when necessary, cast washers of the appropriate dimensions will be used to ensure the correct grip of the screws (5) to the substrate (2).

In those cases in which the matrix of our security element (2) is a thermoplastic, and to optimize the mechanical fixation of this to the cast iron cover, the use of hot welding points or bead is contemplated.

Depending on the surface to cover, geometry and location of the cover (3) of the casket, the minimum number of screws (5) to be used will be specified.

A high strength structural adhesive will be used for chemical fixation, which will be applied in the same way as with the sealant adhesive.

For those covers (3) of boxes that have surface reliefs, these may be overcome by applying a thicker putty cord, where necessary.

In those cases of covers (3) of boxes that are combined with vents (4) of aeration or drainage (7), our safety element (2) will be incorporated by means of “mesh type” covering, leaving the drain holes ( 7) corresponding.

As a general rule, to favor the evacuation of rainwater and allow its circulation, thus keeping the surface dry, our security element (2) will have a drainage system in its own structure.

Once the safety element (2) is installed in the lid (3) of the case, if it is fixed by chemical sealing, in half an hour it will be passable, while by mechanical fixation in just 15 minutes.

Although our safety element (2) is extremely resistant and virtually maintenance free, regular cleaning is required to maintain maximum slip resistance depending on local conditions and traffic volume, being generally sufficient with a hard brush, hot water and soap, although in situations of extreme dirt it can be eliminated by using pressure washing, while maintaining the integrity of the mechanical fasteners and the effectiveness of the adhesive.

The non-slip floor (2) will be of different types of granulation, finishes, surface roughness values, and nominal thicknesses, as well as in various RAL color codes to choose from.

For the correct identification of the data marked on the covers (3), such as marking EN 124, the appropriate class (example D400), name or acronym of the manufacturer, and the mark of the certification body (identification requirements of the standard unites in 124), and if necessary additional markings related to the use or to the owner, and identification of the product (name and / or catalog reference), and when the situation requires it, our element (2) is printable, so that said data will appear as an integral part thereof, and said marks being clear and durable, and as far as possible, should be visible.
