Abstract: A latching mechanism including a pedestal provided with a first hole on the surface, a second member provided with a second hole opened at a position overlapping with the first hole, and a fastening member whose one end part is inserted into and pulled from the first hole through the second hole, so that the second member is engaged with the pedestal in an attachable and detachable manner. In the mechanism, the fastening member is inserted through the second hole into the first hole and then rotated such that an outer shape of the one end part intersects with one of the first hole and the second hole so that the second member is mounted onto the pedestal, and then it is rotated further or reversely so that the second member is separated from the pedestal.

Abstract: A retaining member for mounting an anti-fog sheet to a shield. According to some aspects, a main shaft of the retaining member, which is rotatably fitted into a support hole of the shield and has a head portion abuting against an outer face of the shield, has an elastic deformation part so as to absorb a load which comes from both the shield and the anti-fog sheet, and which acts on the retaining member by deforming the elastic deformation part.

Abstract: This invention provides a helmet shield attaching mechanism capable of relatively easily and relatively accurately performing an adjustment operation for satisfactorily bringing the inner surface of a shield in a substantially fully-closed state into close contact with the window opening rim portion of a head protecting body. The holding position of stopped means of a movable base member, whose position is held by stopper means of a stationary base member in an at least substantially fully-closed state of the shield, can be selected from one of a plurality of portions of the movable base member substantially in the back-and-forth direction.

Abstract: In the present invention, by inputting an upper head size to a computer in addition to a front & back length-size and a right & left width-size of a head portion of a helmet wearer and by data-processing them, there is employed a configuration in which a kind of the helmet size and a shape of a pad such as a pad, in the region consisting of the head-top portion and the vicinity thereof, or the like, which fit the head portion of the helmet wearer, are to be selected. According to the present invention, it is possible to provide a selection method in which it is possible to easily select a kind of a preferable size of the helmet, and a preferable shape of the pad in the region consisting of the head-top portion and the vicinity thereof.

Abstract: There is a conventional input device wherein a blind operation is easy because a touch panel type operation unit and a display unit are separately arranged at locations distant from each other, but such a conventional input device requires a camera for photographing a user's hand on the operation unit, and image processing for converting the photographed image of the hand and combining the image on the display unit, and thus, simplification of the processing method has been desired. Further, reducing the number of components used for such a device has been desired.

Abstract: In this invention, a visor is configured to be inserted into a slit of a movable plate. One of an engaging projecting portion and an engaging concave portion is provided on the visor, and the other is provided on the movable plate. When the visor pivots in a first direction about the engaging projecting portion, a concave corner portion of the visor comes into contact with a first position regulating portion of the movable plate, thereby impeding the pivotal movement of the visor. When the visor pivots in a second direction, the outer wall surface of the visor comes into contact with wall portions of the movable plate, thereby impeding the pivotal movement of the visor.

Abstract: A helmet which performs good ventilation and which is capable of mitigating the uncomfortable feeling due to the sound is provided. The shock absorbing liner includes front ventilation holes to communicatively connect the front openings to the inside of the shock absorbing liner, outside air paths disposed in a space on an outer side relative to an inner surface of the shock absorbing liner, and communicative holes to communicatively connect the inside of the shock absorbing liner to the outside air paths. The outside air paths include primary flow paths disposed to be connected to the rear opening and secondary flow paths. The communicative holes communicatively connects positions on an outer surface of the shock absorbing liner except positions of the primary flow paths, to the inside of the shock absorbing liner. The secondary flow paths are disposed to connect the communicative holes to the primary flow paths.

Abstract: Provided is a ratchet buckle for helmets wherein an engagement/releasing member having an engagement part is assembled to the buckle, via a pin, between the base member and operating member, and therefore when the operating member is pulled up and rotated in the counterclockwise direction, the front end of the operating member contacts the front end of the engagement/releasing member and the engagement with the tab of the ratchet is released by rotation of the engagement part of the engagement/releasing member, and because the engagement is released by pulling up the operating member by at least twice the conventional pull-up distance, the helmet will not come off from the head as a result of a wrong or inadvertent lever operation and thus safety can be ensured, while the thickness of the ratchet buckle can be kept small.

Abstract: A helmet is provided which is to be worn on the head of a helmet wearer and can be removed from the head with a comparatively small force. Operation for removing the helmet, including preliminary operation for it, can be performed easily and quickly. A recess-projection engaging mechanism to attach a blockish inside pad to a head protecting cap portion side includes an engaging pin on the inside pad side or head protecting cap portion side, and a notched engaging hole on the head protecting cap portion side or inside pad side. When pulling the inside pad outward from inside the head protecting cap portion at least partly, the engaging pin moves relative to outside the engaging hole through a notch of the engaging hole.

Abstract: A touch display including a liquid crystal display having a surface displaying images and a capacitive touch-sensitive panel superposed on a surface of the liquid crystal display and enabling an input operation in reaction to the displayed image; wherein being arranged on the liquid crystal display in order from the surface of the liquid crystal display toward an outer surface of the liquid crystal display, a second quarter-wave plate converting a light passing through into a circular polarization by shifting phase, the capacitive touch-sensitive panel, a first quarter-wave plate having a same orientation to the second quarter-wave plate, a polarizer converting the light passing through into a linear polarization, a decorated sheet protecting an upper surface of the capacitive touch-sensitive panel, and an antireflection layer preventing a surface-reflection of outside light, in order to obtain the antireflection effect while keeping costs low.
