  • Patent number: 8641157
    Abstract: A slide hinge is mounted between a body and a cover of a remote control and has a base and a slide pin assembly. The base has two opposite rails and each rail has a rail slot being curved and defined through the rail. The slide pin has a slide pin, a spring and a guide. The slide pin is mounted slidably through the rail slots and capable of moving along a curved path. The spring is mounted around the slide pin. The guide is slidably mounted around the slide pin and selectively compresses the spring. The slide hinge allows the cover to move along a curved path relative to the body.

  • Patent number: 8166613
    Abstract: A limiting hinge has a stationary limiting washer, a rotating limiting washer, a rotating bracket and a positioning washer mounted around a pintle in sequence. A first resistance is formed between the stationary limiting washer and the rotating limiting washer. A second resistance is formed between the rotating limiting washer and the rotating bracket. A third resistance is formed between the rotating bracket and the positioning washer. Because the first resistance is larger than the second resistance while the second resistance is larger than the third resistance, the rotating limiting washer disengages from the rotating bracket when a huge force is accidentally applied. Therefore, the rotating limiting washer stays still with the stationary limiting washer to prevent breakage.

  • Publication number: 20100000052
    Abstract: A slide hinge has a stationary bracket, a slide, a pivot pin and a rotatable bracket. The stationary bracket is hollow and has a chamber and a rail slot. The slide is mounted slidably in the chamber of the stationary bracket. The pivot pin is mounted securely on the slide and extends perpendicularly from the stationary bracket. The rotatable bracket is mounted rotatably on the pivot pin. The slide hinge has merely four components so that fabricating the slide hinge is easy and fast. Therefore, the manufacturing cost of the slide hinge is low.

  • Patent number: 7533447
    Abstract: A hinge for a portable computer having a monitor with a pivotal end and a main frame with a pivotal end has a sleeve, a washer and a pivotal rod. The sleeve is mounted in the pivotal end of the main frame and has multiple cutouts. The cutouts are formed in the sleeve. The washer has two extensions. The extensions are formed on the washer and selectively engage the cutouts of the sleeve. The pivotal rod is mounted rotatably in the sleeve, is mounted securely in the washer and holds the washer between the pivotal rod and the sleeve. When the monitor pivots to open relative to the main frame of the portable computer, the extensions of the washer engage the cutouts of the sleeve to hold the monitor at a desired visual angle.

  • Patent number: 7509709
    Abstract: A hinge is compact and can hold a monitor securely in an optimum angle even if it is long-term used. The hinge has a body, a pivoting member rotatably mounted on the body and has a pintle, a first positioning element and a second positioning element mounted on the pintle. The first positioning element has a groove formed inclinedly in a front surface at an angle. The second positioning element is simultaneously rotated with the pintle and has a rear surface corresponding to the front surface of the first positioning element and a rib formed diametrically on the rear surface. The rib corresponds to and selectively engages with the groove in the first positioning element with resilience of a resilient element to retain the pivoting member at a determined angle.

  • Patent number: 7506408
    Abstract: A hinge with a limitation function has a shaft, which is mounted with a stationary seat, a male segment, a resilient member, a washer and a rotatable seat, and engages a nut to fasten the above elements. When the movable display panel rotates in relative to the main unit, the movable display panel rotates the rotatable seat, and the rotatable seat further rotates the shaft. The male segment also rotates in relative to the female segment; meanwhile, the head is rotate along the fastening portion. When the lugs are engaged in the notches respectively, the display panel is positioned at a certain position, the plane face is against the fastening portion so that the shaft cannot rotate continuously to the same direction.

  • Publication number: 20090070961
    Abstract: A simultaneous-rotating hinge has a body, a first leaf and a second leaf. The body has a gear assembly. The gear assembly is mounted in the body and comprises multiple gears that engage each other. The first leaf is mounted rotatably on the body and connects to one of the gears in the gear assembly. The second leaf is mounted rotatably on the body and connects to another gear in the gear assembly. Interaction of the gears causes the first leaf and the second leaf to pivot simultaneously toward or away from each other.

  • Patent number: 7500288
    Abstract: A hinge has a barrel, a resilient positioning sleeve, a combination leaf-pivot pin and a fastener. The positioning sleeve is mounted rotatably in the barrel and has an inner surface, a stepped expansion slot and at least one flat surface. The expansion slot is formed longitudinally through the positioning sleeve. The flat surface is formed opposite to the expansion slot on the inner surface. The combination leaf-pivot pin has a distal end, a proximal end, a leaf and a pivot pin. The pivot pin protrudes longitudinally from the leaf and has a positioning ring and a connecting shaft. The positioning ring is mounted in the positioning sleeve and has an outer surface and two flat surfaces formed opposite to each other on the outer surface and selectively corresponding to and seating in the flat surface in the positioning ring. The fastener connects to the connecting shaft.

  • Publication number: 20080229546
    Abstract: A position hinge has a pintle having an enlarged head, an inner bracket mounted securely around the pintle, an outer bracket mounted rotatably around the pintle, a positioning assembly mounted around the pintle and having an outer positioning member abutting and rotating simultaneously with an inner side of the outer bracket and an inner positioning member selectively engaging with the outer positioning member, a resilient element mounted between the inner positioning member and the inner bracket and a spacer assembly mounted between the outer bracket and the enlarged head of the pintle and rotating simultaneously with the outer bracket. Because the spacer assembly is mounted between the outer bracket and the enlarged of the pintle and rotates simultaneously with the outer bracket, the outer bracket is protected from being worn off by the enlarged head of the pintle and has a longer life span.

  • Patent number: 7409746
    Abstract: A swivel hinge has a base plate, a first loop, a first rotating board, a second loop, a mounting member, a second rotating board, a pivot member, a third loop, a third rotating board, and a locking ring. When the display panel rotates relative to the main board in a same plane, the third rotating board will not rotate, only the first and second rotating boards rotate relative to the base plate and provide an anchor and limitation function. When a direction of a camera on the display is to be adjusted, the third rotating board rotates with the second rotating board, thus the camera can rotate according to the shooting angle.
