FR3068231A1 - SILICONE EXCAVATOR FOR DUST AND DUST COLLECTION - Google Patents

Abstract

The invention relates to a scoop for the collection of sweepings and dust composed entirely of silicone thus rendering it indeformable and unbreakable. It consists of a receptacle (A), a visor (B) which keeps the sweepings and waste in the hollow of the receptacle, and a handle (C). The material that makes up the shovel is silicone, undeformable and unbreakable, unlike other shovels on the market that are deformable (iron shovels) or breakable (shovels hard plastic). This invention is intended for the collection of waste, dust and sweepings in domestic and professional environments.

Description

Silicone shovel for dust collection and sweeping.

The invention relates to the technical field of cleaning, professional or domestic.

The shovel is generally known as a part which serves as a receptacle for collecting sweepings, dust and other waste. To this receptacle is fixed a handle which allows the maneuverability of the shovel. These shovels are either plastic or metal, however these two materials have drawbacks.

The metal shovels are very noisy when they fall and are deformable at the level of the plating joint on the ground due to a potential shock. If the metal plating joint is deformed, the shovel becomes unusable because the dust passes under the shovel when it is swept away, the shovel is no longer pressed against the ground.

To remedy this, plastic shovels were created which are very fragile and break or split at the slightest pressure or the slightest shock.

The invention makes it possible to remedy these technical problems. Indeed, it concerns the material making up the shovel. Starting from the fact that the iron deforms and that the plastic breaks, the solution is silicone. The silicone is flexible and has both the rigidity necessary to compose a shovel. Its flexibility makes it a non-deformable element since it always regains its initial shape regardless of the shock or pressure that can be exerted on it. The use of silicone would make the shovel almost indestructible, this allows it to last over time unlike today's shovels that consumers do not keep long especially in the professional sector of cleaning.

The invention also has the characteristic of having a flap or a visor which does not cover the entire receptacle but only the 1/4 in order to keep the sweepings in the hollow of the shovel and not to receive dust projections on the hands when scanning and picking up.

The drawings provided in the appendix show the visor of the shovel but not the silicone material:

Figure 1 shows the diagram of the side view of the shovel.

Figure 2 shows the top view of the shovel.

Figure 3 shows the overview of the shovel.

The realization is done simply using a mold corresponding to the desired shape of the shovel. A silicone elastomer is synthesized and poured into the mold, when it is removed from the mold, a silicone shovel is then created. The invention is intended for marketing in supermarkets and in stores specializing in the cleaning field.

Silicone elastomers: created for their elastic virtues.

When a stretched rubber returns to its initial state, each macromolecule regains its most probable shape, corresponding to the highest entropy.

This return supposes that during the stretching, there is no sliding of the macromolecular chains with respect to each other. In this case, there is a permanent deformation; to avoid this, the chains are crosslinked (formation of a network of polymer chains): this is the vulcanization operation.

Vulcanization consists in creating a certain number of covalent bonds between the chains of elastomers so as to form a three-dimensional network and to prevent creep (stretching, irreversible deformation) which would inevitably occur under stress.
