A precision roller wheel assembly for use on a lower surface of a door, especially a patio door or the like, the assembly comprising a two-piece housing, the two-pieces being a mirror image of each other, for receiving at least one precision machined corrosion resistant sealed roller wheel mounted on an axle, means for mounting the assembly to a patio door or the like, and adjustment means for vertically adjusting the assembly in its position of use.
Abstract:
A hinge assembly system (200) includes a hinge assembly structure (210) and a driving structure (220). The driving structure includes a driving shaft (50), a gear (60) and a sliding unit (70). The gear engages with the driving shaft in a manner such that the gear may drive the driving shaft to rotate but the driving shaft cannot drive the gear to rotate. The sliding unit includes a rack (72). The rack drives the gear to rotate. The driving structure provides a force allowing the hinge assembly structure to cause the hinge assembly to rotate.
Abstract:
A knuckle arm is connected to a machine body and a top cover of a machine, and includes a mounting seat, a connecting seat, a sliding seat, and a resilient member. The mounting seat includes a mounting block disposed fixedly on the machine body, and a pivot block extending integrally from the mounting block and having a cam edge. The connecting seat is connected pivotally to the pivot block of the mounting seat, and is attached to the top cover. The sliding seat is disposed slidably within the connecting seat, and has an integral projection. The resilient member is disposed between the mounting seat and the sliding seat, and biases the sliding seat to move toward the mounting seat so as to keep the projection of the sliding seat in contact with the cam edge of the mounting seat.
Abstract:
A door hinge device includes a hinge shaft fixed to a body of an appliance and having a damping protrusion on one side of an outer surface, and a coupling member having a shaft engaging hole coupled to an outer surface of the hinge shaft. The shaft engaging hole includes a holding portion having an inner diameter corresponding to an outer diameter of the hinge shaft and a damping portion having a larger inner diameter than the outer diameter of the hinge shaft and surrounding the damping protrusion. The damping portion includes a separation section separated from the damping protrusion when the door is closed, and a contact section contacting the damping protrusion when the door is opened. The door hinge device can prevent slamming or trembling when the door is opened or closed, and has a simple configuration.
Abstract:
A hinge device where height adjustment, depth adjustment and side adjustment are permitted, wherein a hinge flap is adjustably supported by a rotatable pin with a polygonal flange, the hinge for side adjustment having an adjustable screw body fastened into the door frame for abutment with the rear side of the hinge, and where depth adjustment is provided by allowing a tongue on the hinge flap to form rotatable engagement with a double-headed adjusting screw that is insertable into the door frame parallel to the plane of the hinge flap.
Abstract:
The invention relates to a guide device for a sliding door guided by means of a carriage in a guiding rail. The guiding rail has a channel disposed on its inside, in which the carriage is guided, and is provided with two profile parts releasably connected to each other.
Abstract:
A hinge assembly (200) for joining a cover section (110) to a body section (120) of a foldable electronic device (100) includes a main shaft (10), a rotating member (20), a sliding member (30), and a spring (40). The main shaft has a fixing portion (12) at one end, a deformed shaft portion (14) at its central section, and a distal shaft portion (16) at the other end. The rotating member receives the distal shaft portion, and the rotating member includes an engaging portion (24). The sliding member engages with the deformed shaft portion. The sliding member has a deformed hole (34), engaging with the engaging portion of the rotating member. The spring surrounds the main shaft and elastically biases between the sliding member and the fixing portion. The hinge assembly is modularized, easy to install, and low in cost.
Abstract:
A push-button hinge for a handheld device. The hinge comprises an axially movable button having a push surface and a helical portion for converting axial movement of the button to rotation, a helical follower engaged with the helical portion for rotating in response to the axial movement of the button, a cam rotatably movable with a flip part of the handheld device, a cam follower engaged with a cam profile of the cam and rotatably movable with the helical follower, and a biasing member for urging the cam against the cam follower. The cam profile includes an area initially resisting opening of the handheld device that is overcome by rotation of the cam follower in response to the axial movement of the button. The cam profile further includes a slope for causing rotation of the cam with respect to the cam follower due to the biasing member, thus rotating the flip part and opening the handheld device.
Abstract:
A device (1) for use with a cable-operated door (3), such as garage doors (3) and the like, and a door assembly including the same. The device (1) is intended to reduce the risk of the door (3) falling, or at the very least slow down its descent, in the event of a failure in the counterbalancing mechanism of the door (3), which is generally represented by a loss of tension in a given tensioned cable (5) operating the door (3). The brake device (1) includes a support bracket (9), and a guiding assembly 15 and a braking assembly 17 mounted onto the support bracket (9). The braking assembly includes a swivel component (18) having opposite braking arm (19) and lever portion (20), the lever portion cooperating with the tensioned cable (3) so that in the event of a loss of tension in the cable (5), the braking arm (19) is urged onto an adjacent rail (7) via biasing means (21) for anchoring a knife (45) of the braking arm (19) into the rail (7) and stopping, or at the very least, slowing down the descent of the door (3), with respect to the rail (7).
Abstract:
A door closer includes a closer casing, a pivot unit, and a length-variable damping cylinder. The pivot unit includes a pivot axle, a cam member, and a cam follower member. The pivot axle has a drive end portion that extends into and that is retained rotatably in the closer casing, and a coupling end portion that extends out of the closer casing. The cam member is mounted co-rotatably on the drive end portion of the pivot axle. The cam follower member is disposed in the closer casing, and is acted upon by the cam member. The damping cylinder is disposed in the closer casing, and has one end coupled to the cam follower member and an opposite end anchored to the closer casing.
