Abstract:
A hinge assembly for use with a pivotally movable closure panel is operable to provide a counterbalancing force to lock or hold the closure panel in an open configuration against a predetermined threshold closure force without the need of separate support components such as gas-charged struts or prop rod. The hinge assembly is provided with upper and lower hinge arms which are pivotally connected towards their rearward ends for movement relative to each other for pivotal movement about a hinge pivot axis. A generally elongated or guide slot is formed in the lower hinge arm. A prop arm is pivotally secured at a first end to a forward portion of the upper hinge arm forwardly from the hinge pivot axis. A sliding member is secured toward the second other end of the prop arm and engages the guide slot so as to be reciprocally movable therealong as the hinge arms are moved between a fully closed and fully open positions. The guide slot includes an operational section and an engaged section. A resilient biasing member is used to engage and bias the sliding member forwardly relative to the guide slot as it moves through the engaged section while disengaging from or passively engaging the sliding member as it moves along the operational section of the guide slot.
Abstract:
Device for securing a soft ending of the opening movement of a drawer as the latter is drawn towards an outer limit stop (10), the drawer being mounted in a (not-shown) furniture body and capable of being pulled out from said body, and in which there may be one or more rails (1, 3) between the drawer and the furniture body. The device comprises a damper (6) filled with a fluid medium attached to the furniture body—or to a rail of the furniture body—and a piston with a piston rod (7) being reciprocable in said damper (6), the free end of the piston rod (7) being attached to a tilt-able rocker (9). Whenever the piston rod (7) close to its outermost position is moved in and out in the damper (6), the rocker can be moved on a guide portion (17)—mounted at the damper (6)—between a first end position (FIG. 2) close to the damper, in which a first pin (19) mounted at the back of the drawer may engage with the rocker (9), and a second end position (10) far from the damper (6), in which the piston rod (7) is in its outermost position. This device can work in an especially reliable way.

Abstract:
To securely maintain a rotatable rail in a position where it can receive a plate-like object again after the plate-like object has left the rotatable rail.[Means to Solve]When a sliding door (3) as a plate-like object is moved in a front and rear direction from a closed position to an opening preparation position, a rotatable rail (20) rotates from a horizontal lying position to a vertical standing position about a rotation axis (L1). When the sliding door is in the opening preparation position, a roller (40) of the sliding door (3) rides on a running track (25b) of the rotatable rail (20). When the sliding door (3) is further moved from the opening preparation position to an open position, the roller (40) transfers from the running track (25b) to an auxiliary track (26) of an adjacent rotatable rail (20). The rotatable rail (20) is biased toward the standing position by an elastic force of a torsion spring (18) and maintained in the standing position by an arm (13). This allows the sliding door (3) to be returned to the opening preparation position.
Abstract:
The present invention provides a door opening assist device comprising a spring-biased piston having a threaded bore mounted in a cylindrical housing by a threaded bolt. The piston retains a spring within the housing at a first end of the housing. The threaded bolt engages the piston from a second end of the housing. The piston is retained within the housing by the cooperative engagement between the spring urging the piston out of the first end and the head of the bolt in abutment with the second end. The door opening assist device is installed in a door frame of an automobile to push the door open a predetermined distance. The door opening assist device provides various mounting options. Upon closing the door, the door abuts and retracts the piston into the housing compressing the spring. Upon unlatching the door, the piston extends under spring bias in such a direction and with sufficient force to push the door to an open position a predetermined distance. The cooperative engagement between the bolt and the piston provides adjustment feature to tailor the opening characteristics of the door opening assist device to control the opening of the door.
Abstract:
In a multi-link hinge assembly for a rear deck lid or front hood for an automobile, a torsional coil spring is mounted with its coil coaxial to or proximate to a pivotal connection of the hinge assembly with arms of the coil spring engaging members of the hinge assembly to bias them for pivoting about the pivotal connection. The torsional coil spring provides enhanced “pop-up” of the lid or hood on initial unlocking and can reduce the need for or size of a primary biasing mechanism to assist in opening the lid or hood.
Abstract:
A rotary damper includes a cylindrical member having walls on an inner peripheral surface of a cylindrical chamber along a radial line, and a rotor member having vanes moving along the inner peripheral surface of the cylindrical chamber. A resistance force of a viscous fluid filled in the cylindrical chamber is applied to the vanes when the cylindrical member rotates relative to the rotor member. The rotor member is formed of a thermoplastic resin containing inorganic filler or fiber. Thus, the rotor member having high strength can be obtained.
Abstract:
Disclosed is a hinge for a vehicle lid, the hinge comprising a main biasing means operable to urge the hinge into an open position, and a mechanism for assisting the initial opening of the hinge from a closed position, the mechanism comprising a rotary cam engagable with another portion of the hinge to provide said assistance, and further biasing means which acts on the cam to rotate it relative to said other portion of the hinge. Also disclosed is a lifting aid comprising a main biasing means for attachment between a lid and a body, which lid is pivotally moveable towards and away from the body, the main biasing means being operable to urge the lid from a closed position relative to the body to an open position, the lifting aid further comprising cam means attachable to the body for relative rotation thereto and further biasing means for attachment between the body and the cam means and operable to rotate the cam means relative to the body and lid, the cam means being operable to assist the initial opening of the lid.
Abstract:
A hinge for a vehicle lid comprises a main spring means (112) operable to urge the hinge into an open position, and a device (114) for assisting the initial opening of the hinge, the device comprising an elongate body in which a plunger (116) is sliceable, the plunger being engageable with the hinge, and spring means disposed in the body and acting on the plunger to urge it into an extended position. The plunger is cylindrical and is retained in a cylindrical cavity in the body by an annular fastening, the fastening being formed with one or more radially projecting ribs which engage with an annular recess at the opening of the cylindrical cavity to attach the fastening means to the body. The plunger is formed such that in the extended position disengagement of the one or more ribs from the annular recess is inhibited, preventing the plunger from forcing the fastening out of the body. A bracket extends from a wall of the body to define a slot between the member and the wall, enabling the device to be mounted upon a link of the hinge.
Abstract:
A hinge and linkage system comprises a four-link system wherein first and second links are respectively connected to vehicle body and closure members, and an additional pair of links interconnect the first and second links. An expansible gas strut also interconnects the first and second links. In accordance with the invention, an expansible spring-biased plunger mechanism is mounted upon one of the additional links so as to operatively engage and be axially compressed by the second link and the closure member when the closure member is disposed at its latched position. When the closure member is unlatched, the spring-biased plunger mechanism initially partially elevates the closure member toward its open position whereupon the expansible gas strut can continue the elevational movement of the closure toward its open position.
