  • Patent number: 10278446
    Abstract: A shield for a helmet includes a shield having a sun visor rotatably and axially supported at a position different from a rotation center of the shield. The sun visor rotates within a range from a first position where the sun visor, like a bill of a hat, lies above a front opening part and projects forward to a second position where the sun visor lies outside facing the shield in an overlapping manner, and the sun visor is retained in the first position. The sun visor is operated and moved forward and away from the shield to rotate from the first position to the second position.

  • Patent number: 8584264
    Abstract: A cheek pad for mounting on an inside of a helmet shell includes an attaching member and a cushion member, the attaching member including a base member mounted in contact with the shell and a form-maintaining member disposed at an inner lower section of the base member in a space provided with respect to the cushion member for simultaneously keeping a surface of the cushion member in a profile corresponding to the cheek and chin of a wearer when the helmet is worn by a wearer and, following displacement that causes the space to contract, is restored so as to return to an original location under normal circumstances, and kept there. Elastic members are positioned in the space between the base member and the form-maintaining member to help restore the space to an original configuration subsequent to contraction.

  • Patent number: 8387224
    Abstract: A mounting part for mounting spectacle frame components such as lugs can be machined after confirming that a lens thickness at a mounting part-machined portion where the mounting part is machined is equal to or larger than the specified value, and can be installed the spectacle lens components on the spectacle lens with a requested strength. The device, the method for the above, a spectacle lens manufacturing method, and a spectacles manufacturing method are given. The spectacle lens (1) is fed to a lens thickness measuring device (70) by a lens feeder. The fed amount of the spectacle lens in this feeding is based on the measured results of a distance between a frame center forming a block center by a lens holder in an edging for manufacturing the spectacle lens (1) from a raw material lens and the edge face of the spectacle lens (1) where the mounting part is to be machined.
