Abstract:
A hinge has a first bracket, a first pivot pin, a second pivot pin, a second bracket and a positioning and limiting assembly. The first pivot pin is on the first bracket. The second pivot pin is mounted rotatably on the first pivot pin and has a mounting recess. The second bracket is mounted pivotally on the second pivot pin. The positioning and limiting assembly is mounted in the mounting recess in the second pivot pin and has a seat, a positioning disk and limiting disk. The seat is mounted in the mounting recess. The positioning disk is mounted to the first pivot pin and detachably engage the seat. The limiting disk is mounted to the first pivot pin and selectively abuts seat. The positioning and limiting assembly in the mounting recess makes the hinge compact and easily apply to portable devices such as cell phones and digital cameras.

Abstract:
A hinge of a LCD has a stationary bracket, a first shaft assembly and a second shaft assembly. The LCD had a base and a screen. The stationary bracket is attached to the base. Each shaft assembly is mounted pivotally on the stationary bracket and has an adapting bracket to be attached to the screen. The first shaft assembly has a stationary limiting element, a switching element and a rotating limiting element. The stationary limiting element has a limiting recess with two ends and a narrower stop formed in the limiting recess. The rotating limiting element is pushed by the switching element and has two stops. Pushing the switching element to change the stops of the rotating limiting element respectively corresponding to the narrower stop or the ends of the limiting recess to adjust the limitation of the rotating angle of the screen.
Abstract:
A hinge has a first bracket, a pivot pin, a second bracket and two torsion spring assemblies. The first bracket has a support and two holders. The pivot pin is mounted rotatably through the support and the holders on the base of the first bracket. The second bracket is mounted to the pivot pin. The torsion spring assemblies are mounted on the pivot pin, correspond respectively to the holders on the first bracket and each torsion spring assembly has a disk and a torsion spring: The disk is mounted securely to the pivot pin and has a spring hook. The torsion spring is mounted around the pivot pin and has two ends. One end is mounted securely on the corresponding holder and the other end is engaged detachably with the spring hook on the disk. The torsion springs provide a recovering force to keep the pivot pin from pivot inadvertently.
Abstract:
A rotatable hinge includes a fixed frame provided to be adapted for engagement with a laptop computer base and a rotatable portion rotatable relative to the fixed frame and provided to be adapted for engagement with a laptop computer screen. The fixed frame is composed of a circular wall and a connection base integrally formed with the circular wall. The rotation portion has an extension extending from a bottom of the sleeve to be received in a through hole defined in the circular wall so that the rotation portion is able to be rotatable relative to the fixed portion. The extension has a flange formed thereon and a sectorial block formed on an outer periphery of the flange. The circular wall has a limiting boss formed on a peripheral edge thereof to be selectively connected to the sectorial block so as to limit the rotational movement of the rotation portion relative to the fixed frame.
Abstract:
A hinge is mounted in an appliance with a cover and a base and has a stationary bracket, multiple resilient spacers and a pintle. The stationary bracket is attached to the base of the appliance and has a tubular sleeve. The resilient spacers are mounted securely in the sleeve. The pintle is attached to the cover of the appliance and is mounted rotatably in the resilient spacers. With multiple resilient spacers, the area to provide friction between the resilient spacers and the pintle is increased. Therefore, the friction between the resilient spacers and the pintle is increased and is sufficient to easily hold the cover at any desired angle.
Abstract:
A hinge includes a sleeve and a shank. The shank is composed of an elongated body, a connecting portion and a securing portion. The connecting portion has a diameter smaller than that of the elongated body and larger than a diameter of the securing portion. The sleeve has an inner diameter smaller than that of the connecting portion such that after the connecting portion is received inside the sleeve, an interference fit is existed between the sleeve and the connecting portion of the shank.
Abstract:
A pivot device has a pivot axle fastened on a cover of a lap top computer, a seat fastened on a chassis of the computer, and a first ring and a second ring respectively mounted around the pivot axle. The second ring and an elastic device are respectively mounted on the seat, and the second ring has two cutouts. Two lugs are respectively defined on the first ring and correspond to the cutouts. A nub is formed on an outer circumference of the first ring so that the nub presses against the elastic device. Hence, the cutouts are mated with the lugs by pushing so that the cover can be raised or lowered to the chassis and can be controlled to prevent colliding with the chassis.
Abstract:
A hinge with a torsion spring has a base, a pintle, at least one torsion spring, two joint members, and two washer assemblies. The base is attached to a support of an LCD display, and the pintle is mounted through the base. The torsion spring is mounted around the pintle, one end of the torsion spring is attached to the base, and the other end is attached to the joint member. When the angle of the display is adjusted, the joint members rotate relative to the pintle. With the torsion resilience provided by the torsion spring, the support will not be rotated with the joint members, so that the users can adjust the display angle with one hand.
Abstract:
A pivotal device has a sleeve and a shaft. The sleeve has at least one notch defined in the sleeve. The shaft has two opposite plane surfaces formed on the shaft and two arcuate surfaces formed respectively on the shaft adjacent to the corresponding plane surfaces whereby the arcuate surfaces selectively engage the at least one notch. The sleeve is mounted securely on a chassis of a laptop. The shaft is mounted securely on a cap of the laptop. When the cap is rotated relative to the chassis, the shaft is rotated relative to the sleeve. The notch engages one of the arcuate surfaces so the cap is closed without collision.
