Abstract:
The lifting device comprises a biased slide shoe adapted to be slidable with respect to a member of an openable structure, a lifting arm having two ends, one end adapted to be pivotally connected with a member of the structure and the other end associated with said slide shoe, and a braking device comprising at least one brake shoe slidable on a respective brake face of said lifting device, said braking device modulating the force resulting from the bias on said biased slide shoe. An adjusting device is adapted to adjust said progressive modulation of said force resulting from the bias on said biased slide shoe, and comprises a manipulation member, which when manipulated by a user activates said adjusting device to adjust a brake force of said brake shoe exerted on said brake face in a given position of said brake shoe.
Abstract:
A vehicle sliding door mechanism is arranged to move a door from a door opening provided in a vehicle side body structure from a closed position to an open position. The sliding door mechanism comprises an upper slide rail and a lower slide rail fixed to the vehicle side body structure. An upper slider is associated with the upper rail and is movable along the upper rail, and a lower slider is associated with the lower rail and is movable along the lower rail. An upper link assembly operatively connected to the vehicle door and the upper slider, and a lower link assembly is operatively connected to the vehicle door and the lower slider. At least one link assembly of the upper link assembly and lower link assembly is configured to control a moment of force about a pivot axis while moving the vehicle door between the closed position and the open position. The moment of force is one of an opening moment and a closing moment and is dependent on a position of the vehicle door relative to the vehicle side body structure. The at least one link assembly is configured such that the moment of force is substantially zero between when the vehicle door moves between the closed position and the open position.
Abstract:
A hinged slide rail with buffering function, which includes a rail to which a hinge is mounted. The hinge has a movable blade and a fixed blade between which a buffering device is coupled. The buffering device is housed in a retention frame. The retention frame has an end forming a limiting structure. The buffering device has an active rod coupled to the limiting structure. The movable blade includes a pull bar that is connected to the limiting structure. The hinged slide rail is installed between a door panel and a body of a cabinet to remarkably enhance the convenience of operation and eliminates the potential problems of generating noise and clamping and hurting users.
Abstract:
A sliding assist mechanism includes a case (1) attached to one of a main body (7) and a mobile body (A); a latch (4) movably disposed in the case and switched between a standby state in which the latch is locked in the case and a retracted state in which the locking is released; a biasing device (3) for biasing the latches in one direction; and an operation member (8) attached to the other of the main body (7) and the mobile body. When the latch (4) is switched.from the standby state to the retracted state, the sliding assist mechanism allows the mobile body to move from a first position to a second position on a main body side through the operation member (8) by biasing force accumulated in the biasing means (3). Essential parts of the mechanism include an engagement portion (42) at a normal time when the latches (4) engage the operation members (8) by interlocking the switching from the standby state to the retracted state, and an auxiliary engagement device (47) releasably engages the operation members (8) when the latch comes to the retracted state in a non-engaged state of the operation member relative to the engagement portion. A repairing structure can be further simplified by such sliding assist mechanism.
Abstract:
In an acceleration and deceleration device which includes at least one energy storage device and a cylinder with at least one piston movably disposed in the cylinder and moved therein by a carrier element and a sliding door including a slidable door panel provided with an acceleration and deceleration device, a second carrier element is provided guiding either the first piston or the second piston for movement in the cylinder so as to control the movement of pistons and of the sliding door neat its end positions.

Abstract:
An operator cab for heavy equipment is described to prevent a sliding door mounted on the cab from rocking or rattling in X, Y, and Z-axis directions due to a shock or vibration applied to the cab in a state that the sliding door is fully opened. The operator cab includes an outer sidewall having a doorway formed thereon; upper and lower rails provided on upper and lower portions of the outer sidewall and engaged with upper and lower rollers; a sliding door being slid by upper and lower rollers engaged with the upper and lower rails; an upper pad formed on an upper bracket; a lower pad formed on a lower bracket; an upper stopper, installed in the opened position of the outer sidewall, for being in surface contact with the upper pad when the sliding door is fully opened, and preventing the sliding door from rocking when the upper stopper becomes in surface contact with the upper pad; and a lower stopper, installed in the opened position of the outer sidewall, for being in surface contact with the lower pad when the sliding door is fully opened, and preventing the sliding door from rocking when the lower stopper becomes in surface contact with the lower pad.
Abstract:
A cushioning device for opening and closing of sliding shutters, particularly of sliding shutters for furniture, to be applied as a single item to each shutter or sliding partition, in order to be able to cushion an end part of their opening and closing movement. The cushioning device includes a cushioning box applied with brackets for support and sliding of the individual shutter; this box being equipped with two opposing braking devices of a rotary type, whose toothed hub directly meshes with a rack fixed to the box, each braking device being joined to its own slider guided by the box and being joined at one end by an elastic device with its opposite end joined to the other slider, both sliders being equipped with a hook for activating and deactivating the corresponding action of the final section of travel to be cushioned.
Abstract:
A catcher (2) provided in a door frame H′ for capturing a striker body 1 moved from a near front side F when a door D′ is rotated toward a reference position; a braking device (5); and a linkage device (3) for both are provided. The catcher (2) is provided to be reciprocatingly rotatable between a standby position and a rotated position, captures the striker body (1) at the standby position, and rotates forward to the rotated position. Braking of the braking device (5) is applied to a rotation toward the rotated position of the catcher (2) through the linkage gear member (30).
Abstract:
A door closure device that comprises a mounting member having a top surface, a bottom surface, two side surfaces, a back surface and a front surface. The door closure device also includes at least one magnetic member mounted on the mounting member, such that it is recessed in the front surface of the mounting member. The device further includes at least one damping device mounted on the mounting member adjacent to the at least one magnetic member, wherein a portion of the at least one damping device protrudes from the front surface of the mounting member, past the at least one magnetic member on a front face thereof.
