Abstract:
The invention relates to a ski boot of the type comprising a shell, at least one spoiler and clamping means constituted by a lever, a clamping member, a toothed piece designed to cooperate with said clamping member, and whereinthe toothed piece is housed between two parallel side walls molded with the boot, and defining between them an open chamber on the edge of the spoiler or of the shell, and the height of which substantially coincides with the height of the toothed piece;and the end of said chamber:is, on the one hand, extended at the top by a streamlined structure which is progressively joined to the front of the spoiler or of the shell;and on the other hand, comprises a split part, perpendicular to the walls and situated plumb with the beginning of said streamlined structure.
Abstract:
A ski boot consisting of a shell to receive the foot and of a rear collar hinging on the shell to snugly fit against the leg, the shell comprising on its rear side a raised molding pointing outward for the purpose of limiting the displacement of the collar on the shell, characterized in thatthe collar at its lower part comprises a raised molding parallel to the raised molding on the shell but pointing into the boot and capable of resting on said molding on the shell, andthe shell comprises at its rear part a compressible element capable of resting on and cooperating with said raised molding of the collar when said collar moves on the shell.
Abstract:
A method for manufacturing a correctable lens for glasses from an injectable thermo-plastic polymer material, or other moldable polymer, includes the step of molding a polymer blank provided with the contour of the corrective lens. The polymer blank is joined with a peripheral piece having the same internal radius of curvature as that of the polymer blank creating a lens blank. The internal face of the lens blank is ground and polished to obtain the desired ocular correction. The polymer blank is then separated from the lens blank, the lens blank now being the corrective lens ready for assembly with the frame.
Abstract:
The invention concerns eyewear with means for interchanging a lens including non-rectilinear assembly zones provided on lateral edges of the lens, zones for receiving the assembly zones, one of which is formed at least partly by a piece mobile relative to the frame, and retaining means for normally maintaining the mobile piece in an engagement position.
Abstract:
The present invention relates to a ski boot made of plastics material comprising a shell adapted to receive the foot, whereinthe rear part of the shell presents a rigid, flexible portion which follows the shape of the bottom of the rear face of the leg;and the rear of the boot presents a means adapted to push this rigid, flexible portion towards the front of the shell.
