Abstract:
An obstruction detection device for a motor vehicle having a door assembly movably connected to a vehicle body is provided. The device controls the vehicle door's opening angle to prevent inadvertent contact with an object foreign to the vehicle, while providing the largest opening for vehicle ingress and egress. The obstruction detection device includes a controller that is operatively connected to at least one sensor configured to actively monitor and transmit signals to the controller indicative of the presence and corresponding proximity of the object relative to the door assembly. An actuator is operatively connected to and controlled by the controller. The actuator is configured to apply a selectively variable force that restricts the movement of the vehicle door assembly with respect to the vehicle body when the door is a predetermined distance from the object.
Abstract:
Disclosed herein is a device for buffering the closing impact of furniture doors. A valve (40) is mounted around a piston rod (23) of a piston (20) in such a fashion that an oil gap (41) is defined between the outer peripheral surface of the valve (40) and the inner peripheral surface of a cylinder (10), the valve having a recessed oil passageway (47) formed on an axial end surface thereof. A protrusion element (50) is integrally formed with a front end portion of the valve (40). The protrusion element (50) has a plurality of oil grooves (51) formed longitudinally on the outer periphery thereof. A check valve (60) is mounted on the outer circumferential surface of the protrusion element (50) in such a fashion as to slidingly reciprocate along the compression direction of oil. whereby when an external load is exerted to the piston (20), the check valve (60) moves along with the protrusion element (50) and simultaneously oil contained in the oil chamber (11) flows through the recessed oil passageway (47) of the valve (40) and the oil gap (41) via the oil grooves (51) defined between the protrusion element (50) and the check valve (60) to thereby absorb an impact generated during the closing of the furniture door.
Abstract:
A hinge (1) for a door opening over a horizontal axis, of the type comprising first and second supports (2, 3) that can be fixed to a compartment structure and to a door, at least rotatably constrained to each other through a pin (10). The hinge (1) comprises a fluidic cylinder-piston damper (9) of the type with internal flow leakage of the fluid contained therein. The damper (9) has a piston (18, 19) with a through-hole (20). The piston (18, 19) can have an appendix (19) that non-sealingly engages a chamber (17) when the door is closed, to increase the dampening. The hinge (1) has elastic means (7) such as a spring, to counteract the falling movement of the door when it is opened. The hinge (1) can be of the cam type, with a cam (4) and an abutment (5).
Abstract:
A damping device for furniture door leaves includes a damping housing that accommodates a damping cylinder, with the housing being connected to a damping carrier that is fastened to a front frame of a furniture piece, wherein the damping carrier accommodates the edge of the front frame between an outside retaining leg and an inside clamping leg and the clamping leg is clamped against the front frame by way of a clamping device. The damping carrier includes a carrier main component that forms an outside retaining leg and a spring component that forms the inside clamping leg and the spring component includes a fastening leg offset at a right angle from the clamping leg that is inserted into a fastening guide of the carrier main component and locks positively on the carrier main component.
Abstract:
An automotive vehicle includes one or more swinging doors which may be immobilized in a number of positions, so as to allow the doors to be used to assist passengers upon entering and leaving the vehicle. The motion of the door may be damped, or stopped entirely, either at the discretion of a vehicle occupant, or automatically, in the event that the door is driven by external forces to swing at a high rate.
Abstract:
An air damper includes a cylinder having a bottom, a piston received inside the cylinder to move freely back and forth coaxially, and an orifice provided in the piston. The piston is formed of a synthetic resin, and has a piston rod extending toward a side of the cylinder opposite to the bottom, and a recess portion provided on a portion facing the bottom in order to prevent sink or the like during molding of the piston. A protruding portion is provided on the bottom of the cylinder to protrude into the recess portion when the piston is fully moved into the cylinder.
Abstract:
Damper for movable furniture parts with a housing and a cylinder disposed in the housing, in which a piston with a piston rod is movably supported therein, with at least one set of gears supported movably on the housing, via which the cylinder and/or a stop for the piston rod can be adjusted relative to the housing.
Abstract:
A damping device (100), in particular to dampen impacts of mobile parts in pieces of furniture, comprises: a casing (1) containing a viscous fluid; a piston (3) slidably mounted inside the casing (1) and defining inside the casing (1) two regions with variable volume, which are in fluid communication at at least one duct defined in the piston (3) and at an hollow space defined between the outer surface of the piston (3) and the inner surface of the casing (1). The damping device (100) is characterised in that the piston (3) comprises a floating shutter (5) suitable for closing the at least one duct defined in the piston (3) during the working stroke of the piston (3) and for opening the at least one duct defined in the piston (3) during the reset stroke of the piston (3). The damping device (100) allows a substantial reduction in the reset force of the piston (3) to be obtained maintaining a particularly simple structure and low manufacturing costs.
Abstract:
A damping device (100), in particular for damping impacts of mobile parts in pieces of furniture, comprises: a casing (1) wherein is defined an inner chamber containing a viscous fluid and substantially closed at one end through a cap (2); a piston (3) slidably mounted in the inner chamber; a stem (4) having a first end (4a) associated with the piston (3) and a second end (4b) projecting from the inner chamber. The damping device (100) is characterised in that the cap (2) comprises at least one floating gasket (28) slidably mounted in a cavity (24) defined in the cap (2), said floating gasket (28) defining a region with variable volume in the cavity (24) suitable for receiving the viscous fluid displaced into the inner chamber by the stem (4) during the movements of the piston (3). The cavity (24) defined in the cap (2) and the floating gasket (28) slidably mounted in it define a system for compensating the variation in volume available in the inner chamber to receive the viscous fluid, due to the insertion/removal of the stem (4).
Abstract:
The invention concerns a cabinet hinge with an automatic opening device, especially for cabinet doors with a hinge cup, which is connected with a hinge to a hinge arm, which is, being adjustable and lockable, connected to a base plate, which is connected to a cabinet body; whereby, the hinge includes an inner and outer joint lever, which are fastened to the hinge cup, as well as the hinge arm, with each one pivoting joint pin, which causes a kind of parallelogram-joint to be formed between the hinge cup and the hinge arm, by which means the cabinet door relative to the cabinet body can be swung out; whereby, at least one elastic resilient spring element directly affects at least one joint pin of outer and/or inner joint lever and causes a torque for opening of the cabinet door from the closed position through a defined opening-angle area, and; whereby, the resilient spring element is fastened to the hinge cup, whereby, at least one resilient spring element affects through a sliding wedge directly or indirectly at least one join pin of the outer and/or inner joint lever. Specifically, the spring element is contained totally inside the hinge cup and includes at least one one-step piston rod-cylinder unit, which allows a relative movement of the sliding wedge towards the hinge cup and its top part during the opening process of the door by means of a spring and during the closing process by means of the strength of the user. The advantage of the spring element position on or in the hinge cup is that considerably more room is available for a heavy spring and heavy doors can be equipped with the automatic opening device, according to the invention.
