Description

Technical area

The present invention relates to a device for protecting the base of a wall intended to rest on the ground and against the lower base of said wall to protect the base of the wall, isolate the wall against microorganisms, facilitate floor maintenance and aesthetically hide the junction between said floor and wall. The invention finds application in the field of the protection of partitions and walls in industrial premises, particularly in the food industry.

Prior art

Nowadays, it is known, in the field of the protection of partitions and walls in particular in an industrial premises, to equip the lower parts thereof baseboard, impact resistant, to protect these lower parts of deterioration that could cause, for example, handling equipment that accidentally hit them.

Such a plinth, particularly in the food industry, must be easily cleaned, for example, by spraying water under pressure so as to remove any traces of dirt likely to be deposited during the production phase. Therefore, the skirting board must therefore have an almost smooth outer surface and must be watertight at its junction with the partition or the wall as well as with the ground to avoid the stagnation of moisture which, when it is loaded with soil, becomes able to promote the development of microorganisms such as, for example bacteria or fungi.

To do this, these skirting known, such as, for example, that disclosed in the US patent application US5,553,431 are made of plastics such as, for example, polyester or polyvinyl chloride and conventionally comprise two flexible sealing lips arranged along their edges in contact with the ground and the wall, and a hollow area in which the fixing means of the screw type or rivets, for example, for maintaining said skirting boards against the wall, said hollow area being covered by a removable cover. This type of baseboard is hygienic, rot-proof, resistant and easy to clean. Said document discloses the features of the preamble of claim 1.

• les plinthes ne permettent pas, malgré la présence de lèvres souples d'étanchéités, d'avoir une étanchéité efficace lors d'irrégularités importantes des supports telles que, par exemple, des chanfreins sur les murs ou encore des joints de carrelage au sol,
• ces plinthes comportent encore de nombreuses zones de rétention (derrière la plinthe, cache vis) qui représentent un risque de développement de micro-organismes et donc une altération de l'hygiène du produit.
• le capot couvrant la zone creuse laisse apparaître des rainures dégradant l'esthétique de la plinthe et créant une nouvelle zone de rétention.
