An object of the present invention is to provide a circularly polarizing plate with the thermally adhering function imparted thereto, a circularly polarizing lens which is reinforced with a backup resin, and is distorted with difficulty, and circularly polarizing glasses for viewing a three-dimensional movie, or a stereoscopic television, in which a lens is dropped off from a frame with difficulty even when the lens collides against objects, is pushed with a finger, or is exposed to change in a temperature or change in a humidity, and which has good appearance, and has a good wearing feeling. There is provided a clockwise or counterclockwise circularly polarizing plate, characterized in that in a multilayered circularly polarizing plate having at least a phase difference functional part, a linear polarizing functional part, and a thermally adhering functional part which thermally adheres to a backup resin, the phase difference functional part is arranged on one side of the linear polarizing functional part, and the thermally adhering functional part is arranged on another side. There is also provided a clockwise or counterclockwise circularly polarizing lens, which is a bending-processed product of the above circularly polarizing plate. There is further provided circularly polarizing glasses, characterized in that the above clockwise circularly polarizing lens and the above counterclockwise circularly polarizing are paired, and placed in one frame.

A belt length adjuster includes a frame body (1) with two outer frames (1a, 1a) and two connecting frames (1b, 1b), and a support frame (2) provided between the two outer frames (1a, 1a) stretching to and between the two connecting frames (1b 1b). The support frame (2) supports one end part (B1) of the belt member (B) to be used with the belt length adjuster. Two inner frames (1c, 1c) are respectively provided between the support frame (2) and the respective outer frames (1a, 1a) stretching to and between the two connecting frames (1b, 1b). The support frame (2) and the respective inner frames (1c, 1c) provide insertion spaces (Sa, Sa) therebetween into which the one end part (B1) of the belt member (B) is inserted, while the respective inner frames (1c, 1c) and the respective outer frames (1a, 1a) provide insertion spaces (Sb, Sb) therebetween into which the other side (B2) of the belt member (B) is inserted. Easy and instant adjustment of the belt length is achieved. The adjuster can be made easily and at low cost. Furthermore the one end part (B1) of the belt member (B) is easily attached to the support frame (2).
摘要:
A fog-resistant structure and a protective device for eyes is configured such that a transparent conductive film is formed on one surface of a lens or shield, a linear electrode is provided on upper and lower portions of the surface of the lens or shield so that each of a central region and opposite side regions of the lens or shield has substantially equal spacing between the upper and lower linear electrodes. Thus each region of the lens or shield has no difference in temperature without regulating power supplied to the transparent conductive film, thereby eliminating wasted power consumption and allowing even a structure using a battery as the power supply to have much longer available time.

A protective device for eyes, for example, goggles (G) of a shield, includes a double lens member (3), a frame member (1) and a face fixation member (2). The double lens member includes a front lens (30), a back lens (31) and a gasket (32). The front lens and the back lens are made of polycarbonate resins, polyurethane resins, polyester resins or polyamide resins. The front lens and the back lens are disposed in parallel with the gasket therebetween in order to form a space surrounded with the front lens, the back lens and the gasket. This device is excellent in the antifogging property in the double lens.

Swimming goggles, wherein belts (3) are fitted to an eye protective eye cup part (1), a mounting/dismounting mechanism (4) for mounting and dismounting the goggles on and from a head part is fitted to the belts (3), whereby since the mounting/dismounting mechanism (4) for mounting and dismounting the goggles on and from the head part is fitted to the belt fitted to the eye cup part, a user can mount and dismount the goggles on and from the head part by merely slightly pulling the belt to connect and disconnect the mounting/dismounting mechanism, and must not extend the belt by pulling to such a length as to provide an allowance for installation on the head, and the swimming goggle making it hard for hairs to be disturbed more than before when installed on the head part can be provided.
摘要:
The synthetic resin lens (1) has a function to generate heat by selectively absorbing infrared rays with wavelengths of 780 to 3000nm. The synthetic resin lens (1) includes an infrared absorber. Selective absorption of infrared rays allows the synthetic resin lens (1) itself to generate heat and thus the lens (1) of the present invention has the same function as being electrically heated to prevent fogging.

Goggles include a lens frame (1) and connection arms (3) for a wearing belt (2). The connection arms (3) are provided respectively at right and left parts (1a, 1b) on a side of a front surface (1c) of the lens frame (1). Each of the connection arms (3) is able to be kept both in a state that the arm (3) overlaps and rests on the front surface (1c) of the lens frame (1), and in a state that the arm (3) stays at a position with a space (S) from the front surface (1c) of the lens frame (1) after having moved rotationally on its inner end (3b) from the front surface (1c) of the lens frame (1) outwardly. The goggles provide a preferable fitted comfortability to a wearer's face regardless of whether he uses a helmet or not and regardless of the thickness of the inner liner of the helmet.
