Selective ventilation helmet for cycling use
The present invention concerns a selective ventilation helmet of the type having a cap structure provided with a plurality of splits which make ventilation channels passing from the inside to the outside of the helmet, A selector is also provided, which is arranged at the splits and moveable with respect to the cap structure between a closing position of the ventilation channels and a position for at least partly opening the ventilation channels, wherein the selector is moveable on a guide integrated in the said cap at the splits.
1. Helmet for cycling use, said helmet comprising:
a cap structure having a front, a back, and a length extending between said front and said back, said cap structure further having an exterior surface and an interior space and being provided with a plurality of ventilation channels passing from said exterior surface at said front of said cap structure to said interior space of said cap structure,
a selector having a length and a width, said selector being provided with a front edge extending transverse to said length, which is arranged at said ventilation channels and moveable with respect to said cap structure between a closing position of said ventilation channels whereby said front edge of said selector abuts said exterior surface at said front of said cap structure and at least one position for at least partly opening said ventilation channels whereby said front edge of said selector is spaced from said front of said cap structure,
wherein said selector is moveable on and superimposed onto a guide frame integrated in said cap structure at said ventilation channels, said guide frame being positioned between said selector and said cap structure, said guide frame extending and traversing said length and said width of said selector and includes a plurality of trusses extending and traversing said length and said width of said selector,
wherein said selector is housed in a seat on said exterior surface of said cap structure, so that in said closing position of said ventilation channels, said selector is flush with said cap structure without a step discontinuity between said cap structure and said selector where said front edge of said selector abuts said exterior surface at said front of said cap structure, and
wherein said selector has an exterior surface being completely exposed in all of the positions, said exterior surface of said selector providing an exterior surface of said helmet along a middle portion of said cap structure and being contiguous with said exterior surface of said cap structure.
2. Helmet according to claim 1 , wherein said guide frame is co-moulded in said cap structure.
3. Helmet according to claim 1 , wherein said guide frame is partly embedded in said cap structure and partly accessible at said ventilation channels.
4. Helmet according to claim 3 , wherein said guide frame has a slotted hole for receiving a pin, said slotted hole being arranged inside said selector such that said slotted hole is configured to have said pin disposed therein.
5. Helmet according to claim 4 , wherein said helmet further comprises a holding element for maintaining said pin in said slotted hole.
6. Helmet according to claim 1 , wherein said selector is adapted to simultaneously open or close said ventilation channels of both sides of said helmet.
7. Helmet according to claim 1 , wherein said helmet further comprises a front grid partly superimposing said ventilation channels, said front grid being positioned between said selector and said guide frame.
8. Helmet according to claim 7 , wherein said selector is moveable above said front grid.
9. Helmet according to claim 7 , wherein said front grid is removable from said cap structure.
10. The Helmet according to claim 1 , wherein said guide frame and said plurality of trusses extend and traverse a full length and a full width of said selector.
11. The Helmet according to claim 1 , wherein said guide frame is a one-piece structure.
