Abstract:
A hinge device for use in an electric or electronic apparatus is provided, in which a pivoting portion moves with respect to a fixed portion around a hinge portion. Accordingly, the hinge device has effects of a simple assembly and an easy maintenance. Also, the hinge device plays a role of a hinge which can freely adjust a torque transferred to the upper bracket to thus generate a proper frictional force constantly and adjust a rotational angle according to an angle formed by the upper and lower contacting portions of the holder.
Abstract:
A door actuating system for the leaf of a fire door includes a safety fuse that detaches the fixture between the housing of the door actuating system and an arm on the door or the door frame, which then falls on the floor and are no longer in contact with the hot surface of the door. Plastic screws and plastic bushings accomodating metals screws or assembly plates made of plastic or similar materials can be used as the safety fuse.
Abstract:
An arrangement is provided in connection with a cellular mobile telephone, having a protective hatch or flip pivotably arranged on a housing of the telephone. The flip is pivotable around an axle and is arranged to be able to physically cover at least parts of a keypad on the telephone. The axle includes passive hinges at its one end for establishing a physical pivotable connection along an axis of pivot for the flip, and an active hinge arrangement at its other end for positively urging the flip to occupy at least one predetermined position. The active hinge arrangement is arranged in a substantially closed compartment or cavity at one end of the housing and is formed from a shaft and a combined torsion/pressure spring arranged thereon. The spring has at its respective ends, fingers acting as counteracting parts of a torsion spring for positively urging the flip from a closed and locked position covering the keypad, to an open use position at approximately 120°-170° from the closed position after release of the lock. The spring also includes press surfaces affected by a cam follower arrangement, thereby obtaining a non-destructive override function for the flip.
Abstract:
A hinge mechanism for assisting the lifting of a trunk lid of a vehicle comprises a V-shaped leaf spring (12) mounted on a first hinge part (2) attached to the vehicle body, and a roller element (32) mounted on a second hinge part (4) attached to the lid. A compressible gas strut (38) may be connected directly between the lid and the body; alternatively the strut may be connected between the first and second hinge parts, (2, 4) so that the resulting sub-assembly can be mounted directly to the lid and body on the vehicle assembly line. The hinge mechanism assists in initially lifting the trunk lid so that the gas strut (38) is disposed in an advantageous leveraged position at which it can continue the lifting movement of the trunk lid.
Abstract:
A hinge assembly for switching a closed position and an open position of two articles by engagement between a first hinge member which is disposed at one of the two articles such that the first hinge member is non-turnable and non-movable in the axial direction and a second hinge member which is disposed at the other article such that the second hinge member is non-turnable but movable in the axial direction, wherein the locking mechanism comprises a plurality of engagement members disposed between the first hinge member and the second hinge member in such a manner as to be away from each other in the circumferential direction, biasing means for pressing the engagement member against the first hinge member, a guide portion for connecting the engagement members, which are disposed at the first hinge member, such that the engagement members are movable only in the radial direction, and a locking portion, which is disposed at the second hinge member, being raised towards the first hinge member and varied in height along the radial direction, the engagement members being locked by a high part of said locking portion, thereby maintaining the first and second hinge members in the closed position, and wherein movement means moves the engagement members from a high side towards a low side of the locking portion in accordance with movement of the control member, which is externally controlled, from the first position towards the second position side, and the first hinge member is turned to the open position by turning force of the biasing means.
Abstract:
A bottom portion 11a is formed on an external end portion of a support sleeve portion 11 which is located on an external side, and an engagement recess 43 is formed in an inner peripheral surface of a support sleeve portion 21 which is located on an internal side. That end face of the engagement recess 43 which faces the support sleeve portion 11 side serves as an engagement surface 44. An engagement piece 45 is formed on one end portion of a hinge body 3. The engagement piece 45 is elastically deformed such that its distal end portion is displaced radially inward of the hinge body 3, thereby the engagement piece 45 is allowed to extend beyond a bottom surface of a key groove 41. Thereafter, the engagement body 45 is elastically restored such that its distal end portion is displaced radially outward of the hinge body 3, thereby the engagement piece 45 is engaged with the engagement recess 43. Then, the engagement piece 45, when abutted with the engagement surface 44 at its distal end face, prohibits the hinge body 3 from escaping from the support sleeve portion 21.
Abstract:
A turning mechanism for providing a turning motion, and a hinged electronic device. The turning mechanism comprises a power element which is arranged to generate the turning force for the turning motion, and a damping element which is arranged to control the speed of the turning motion. The damping element comprises a substantially cylindrical casing inside of which a spindle is mounted using a clearance fit. The power element is connected with respect to the spindle to allow the spindle to rotate inside the casing along with the turning motion. The clearance fit between the casing and the spindle is provided with an elastic medium which controls the motion of the spindle with respect to the casing and dampens the stopping of the turning motion.
Abstract:
A plug for use in a counterbalancing mechanism of a cable-operated door. The plug is mounted about an overhead shaft and used for operatively connecting the overhead shaft to a torsion spring coaxially mounted thereon. The plug includes a cylindrical collar and a cylindrical flange. The cylindrical collar has opposite first and second portions. The collar is provided with a hooking slot for hooking a free end of the torsion spring therein and the torsion spring has a segment coaxially mounted about the first portion of the collar. The cylindrical flange is rigidly affixed to the second portion of the collar. The flange is used for transferring a torque between the torsion spring and the overhead shaft when the flange is securely fixed about the overhead shaft. The plug further includes a shouldering floor of a given length faced against the hooking slot and extending inside the collar, from the second portion towards the first portion thereof, between the collar and the overhead shaft.
Abstract:
A control mechanism for use with a door closer having a pinion shaft. The control mechanism comprises a coiled torsion spring around the shaft with a free end of the spring lying along part of a strap. The strap is connected to the shaft and normally held in tension, in use, by its connection to a movable hydraulic piston of the door closer which is biased in one direction. On normal closing of the door, in use, the strap remains tensioned and the spring is thus prevented from tightening on the shaft. However, if an external closing force is applied to the door, the strap becomes untensioned, thereby allowing the spring to tighten about the shaft to retard its angular door closing movement.
Abstract:
A snap hinge and method of manufacturing includes a plurality of articulated levers interposed between a first member and a second member and reciprocally angularly positionable between first and second end positions. An elastic member is interposed between the levers and at least one of the levers includes side portions and at least one interconnecting portion between side portions. At least one lever cooperates with the elastic member at hinge means that are only defined by one interconnecting portion. The components are punched from a metal stamp and bent with side portions at right angles to interconnecting portions to form hinge means integrally with the side portions.
