  • Publication number: 20040139662
    Abstract: A method of mounting a glass uses a glass holder having a pair of holder pieces. The method includes a process of attaching a dielectric heating adhesive resin to at least one of the holder pieces, and a process of applying a force such that the glass is sandwiched between the holder pieces, and a process of applying a high-frequency dielectric heating to the area where the glass is sandwiched between the holder pieces. The glass holder includes the first and second holder pieces, an attaching structure for attaching the glass holder to another member, and a hot-melt resin. The second holder piece faces the first holder piece with a glass therebetween.

  • Patent number: 4893850
    Abstract: An opening/closing device for detachably coupling a closure member to the open edge portion of a body includes a locking shaft provided upon the side of the body, a bracket secured to the closure member and having a notch defined therein, an operating lever having an end portion provided with a pawl portion for engaging the locking shaft within the open end region of the notch, and spring means provided upon the operating lever for biasing the pawl portion in the direction of engagement with the locking shaft. When the closure member is set upon the body, the notch is engaged with the locking shaft. The closure member is closed relative to the body by the engagement of the notch and pawl portion with the locking shaft. When the closure member is opened in a cantilevered state, this device serves as a hinge. By operating the operating lever against the biasing force of the spring means so as to disengage the pawl portion from the locking shaft, the closure member is separated from the body.

  • Patent number: 4679958
    Abstract: A ball joint comprises a ball stud containing a ball at the leading end thereof, a socket incorporating therein a receptacle for admitting of the ball, and a resilient metallic ring containing a gap therein and adapted to retain the ball rotatably within the receptacle. The receptacle is formed of a main body and an auxiliary body adapted to be attached fast to the main body, and at least the main body is formed of a plastic material. Retention of the ball within the socket is accomplished by setting the resilient metallic ring in position within the receptacle before attachment of the auxiliary body to the main body, driving the ball into the receptacle thereby causing the equator of the ball to widen the gap in the resilient metallic ring and slide past the ring, and consequently enabling the ring to get hold of the ball.
