Abstract
A protector screen for use against arthropods, includes, a sheet having a core made from glass or a plastic material, which is at least partially transparent, and comprising a plurality of ventilation holes, each of said ventilation holes being designed to prevent arthropods from passing therethrough, at least a portion of each ventilation hole being closed by a lateral wall or by contiguous lateral walls forming a single piece that is open at the ends thereof, and the ventilation holes being designed such that a gaseous fluid, such as air, can pass through the screen, while optimising light transmission and optionally cooling the fluid passing through the screen.
Claims10
A protector screen for use against arthropods comprising
- a sheet comprising a core made from glass or from plastic material, said sheet being at least partially transparent, and comprising two faces with a plurality of ventilation holes,
- each of said ventilation holes having ventilation hole openings and being configured to prevent arthropods from passing therethrough, said ventilation holes being intended to allow a gaseous fluid to pass through the protector screen,
- characterized in that at least one of portions of at least some of said ventilation hole openings on said faces has a straight, elongate cross section, said straight, elongate cross section comprising a longitudinal axis and a transverse axis, a dimension of each of said portions along the longitudinal axis being greater than a largest dimension of the arthropods against which the screen provides protection, a dimension of each portion along the transverse axis being less than or equal to a largest dimension of a main body of the arthropods against which the screen provides protection, the main body excluding a head and appendages of the corresponding arthropods,
- wherein each ventilation hole comprises a lateral wall, wherein the lateral wall is unitary for at least some of said ventilation holes, wherein a portion of at least one face of the two faces of said sheet delimiting an edge of each of these ventilation holes and/or the lateral wall comprises at least one layer configured to increase the light transmission coefficient of said sheet relative to the light transmission coefficient of a same sheet whose ventilation holes are not provided with said at least one layer.
A method of using a protector screen against arthropods the method comprising:
- insulating a space from mosquitoes, in particular tiger mosquitoes, with the protector screen while allowing ventilation of the space, said space being intended to be occupied by humans, animals or food,
- wherein the protector screen includes:
- a sheet comprising a core made from glass or from plastic material, said sheet being at least partially transparent, and comprising two faces with a plurality of ventilation holes,
- each of said ventilation holes having ventilation hole openings and being configured to prevent arthropods from passing therethrough,
- said ventilation holes being intended to allow a gaseous fluid to pass through the protector screen,
- characterized in that at least one of portions of at least some of said ventilation hole openings on said faces has a straight, elongate cross section, said straight, elongate cross section comprising a longitudinal axis and a transverse axis, a dimension of each of said portions along the longitudinal axis being greater than a largest dimension of the arthropods against which the screen provides protection, a dimension of each portion along the transverse axis being less than or equal to a largest dimension of a main body of the arthropods against which the screen provides protection, the main body excluding a head and appendages of the corresponding arthropods,
- wherein each ventilation hole comprises a lateral wall that is unitary, for at least some of said ventilation holes, a portion of at least one face of the two faces of said sheet delimiting an edge of each of these ventilation holes and/or the lateral wall comprises at least one layer configured to increase the light transmission coefficient of said sheet relative to the light transmission coefficient of a same sheet whose ventilation holes are not provided with said at least one layer.
