Abstract:
The hinge for wings or doors, in particular of electrical appliances, comprises a first box-shaped body, a second box-shaped body, a connecting element between the first and second bodies, and a damper cylinder for applying on the second body an action damping its movement towards the first body.
Abstract:
A hinge, for automatically-closing a door which opens in both directions, includes a cylinder (2); an operating rod (3) to be rotatable and restricted from moving in the longitudinal direction; two substantially V-shaped grooves (33) provided on an outer periphery of the operating rod (3) in the cylinder (2) to oppose to each other; two spheres (55) provided engage the substantially V-shaped grooves (33); an upper piston (5) engaged with the spheres (55); a compression coil spring (4) disposed between the upper piston (5) and an upper end portion of the cylinder (2) and configured to urge the upper piston (5) to the other end side of the cylinder (2), and a fluid pressure shock absorbing mechanism configured to absorb a shock caused by the movement of the upper piston 5 to the other end side with a liquid pressure.
Abstract:
A door closer has a housing for connection to a door and a drive spindle (10) coupled to the door. As the door moves the spindle (10) and housing (11) rotate relative to one another. The relative movement is translated by a piston and cam mechanism (21, 22) into a force that is used to separate a pair of magnets (28). The magnetic attraction of the magnet pairs (28) serves as a force to resist opening of the door and biases the door from an open to a closed position. At least one first magnet is coupled to the drive member and at least one second magnet (32) coupled to the housing. The magnets are arranged in the housing with their opposite poles facing one another such that there is a magnetic force of attraction between them. At least one further biasing spring (36) may be provided to provide a biasing force after the magnetic force has diminished by separation of the magnets.
Abstract:
A holding element for adjusting a lid (4) of a piece of furniture between a closed position and an open position has a first fitting part (1) that is connectable to the body (2) of a piece of furniture. A second fitting part (3) is connectable to the lid (4). A first support arm (5) is pivotably fastened around a first body axis (7) to the first fitting part (1) and is pivotably fastened around a first lid axis (8) to the second fitting part (3). A second support arm (6) is pivotably fastened around a second body axis (9) to the first fitting part (1) and is pivotably fastened around a second lid axis (10) to the second fitting part (3). A lever (19) is pivotably fastened around a pivot axis (20) to the first fitting part (1). An adjustment arm (26) is pivotably connected to the lever (19) at a distance from the pivot axis (20). The adjustment arm (26) is pivotably fastened around a third lid axis (28) to the second fitting part (3). A drive force (12) urges the lever (19), with a force, to a first pivot direction. In the open position of the lid (4), the first support arm (5) and the second support arm (6) intersect each other.
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 spring buffer for a furniture item has a furniture body and a furniture part movable from a closed position in or on the furniture body. The spring buffer can be arranged relative to the furniture body and the furniture part such that the movable furniture part in its closed end position can be moved against the force of the spring buffer towards the direction of the furniture body. The spring buffer includes a buffer element for the movable furniture part and the buffer element is acted upon by a spring. The buffer element is movably arranged such that the distance covered by the buffer element against the force of the spring can be changeably adjusted.
Abstract:
The invention relates to a damping device with damper arranged on a first part of a piece of furniture or furniture fitting, operable by a second part of a piece of furniture or furniture fitting thus damping a relative movement of both parts, wherein the damping effect of the damper may be deactivated by a switchable coupling switched by means of a preferably manually operated switch body.
Abstract:
A damping device includes a cylinder (11) in which a piston (10) is housed for reciprocable movement. The piston has a skirt (12) which expands resiliently outwardly when the piston is moved in the direction of arrow A to provide a frictional damping force. The interior of the cylinder is undercut at its distal end (13a) to allow the skirt to relax.
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 device for preventing door slamming including a housing that has a bore formed therein, a control element that slides in the bore, the control element having a bore formed therein, a plunger that slides in and out of the bore of the control element, the plunger being biased against a distal end of the bore of the control element by a biasing device, and a stopper element received in the plunger and extending into the control element, wherein a slamming force applied on the plunger dislodges the stopper element from the plunger so that the stopper element becomes lodged in the control element and the housing, thereby preventing the control element from sliding in the bore of the housing.
