Abstract:
A compartment confining construction comprises an opening and a closure unit movably mounted on the compartment confining construction for movement between a closing position and a fully opened position with respect to the opening. A fluid-based positioning unit is connected to both the compartment confining construction and the closure unit, the fluid-based positioning unit having two working chambers interconnected by at least one flow path, a movement of the closure unit corresponding to a flow of fluid from one chamber to another through the at least one flow path. A fluid flow control device is provided for controlling the flow of fluid through the at least one flow path and thereby controlling the movement of the closure unit. The fluid flow control device is actuatable by an electric actuating device. The flow of liquid occurs in response to movement of the closure unit when the closure unit is moved by an external force.
Abstract:
An assembly for controlling turn of a hinge is mounted within one section of a hinged structure such as a laptop, palm-top or handy personal computer. In the assembly housing, there are arranged an elongated pivot, a cylindric plastic sleeve having an aperture for setting the pivot, and a socket having a frusto-conical aperture. The sleeve is usually of a truncated biconical shape and has some slot extends axially to one or other end thereof. The inner surface of the housing bore inclines axially in the opposite direction to the inner surface of the socket so that the inclined inner surface can contact with the other frusto-conical outer surface of the sleeve.
Abstract:
A brake apparatus for automatic doors including a speed pulse signal output device for providing speed pulse signals at a time interval inversely proportional to the door speed of an automatic door, a brake for slowing the door speed, a braking position detector for detecting braking position when the brake starts braking, a brake effect measurer for measuring the effect of the brake and a braking power controller for adjusting the braking power of the brake in accordance with the measured braking effect whereby the motion of the door is kept constant irrespective of the door weight and other conditions.
Abstract:
A friction applying assembly for a panel movable from a first position to a second position which includes a mounting plate rigidly secured to the panel with the plate having a non-circular aperture. There is a hinge support arm having at one end a non-circular aperture and a bolt arm having a head at one end, which bolt arm is inserted into the non-circular aperture of the hinge support arm to prevent relative movement between the bolt arm and hinge support arm. The bolt arm is elongated having a large diameter section adjacent the head and a smaller diameter section at the opposite end and a tapered conically shaped intermediate section between the large diameter section and small diameter section. An elongated bushing body having one end inserted into the non-circular aperture of the mounting plate is secured thereto to prevent relative movement between the bushing and mounting plate. The bushing has an internal tapered conically shaped cavity complementary to and in frictional engagement with the intermediate section of the bolt arm. A compression spring having one end seated against the bushing and the opposite end retained by fastener means on the smaller diameter section of the bolt arm urges the bushing into movable frictional engagement with the tapered conically shaped intermediate section of the bolt arm.
Abstract:
A control system for controlling vehicle door movement along a door sweep trajectory between a first position and a second position, can include one or more controllers, the control system configured to: receive a sensor signal; based on the sensor signal, generate an obstacle detection map of a sensor region in the vicinity of the vehicle, the obstacle detection map comprising a location of an obstacle if present; determine an overlap of the obstacle detection map and a projected door sweep region defined by the door sweep trajectory; and generate an output signal based on the determined overlap.
Abstract:
A hinge structure connected between two bodies of an electronic device is provided. The bodies are rotated to be folded or unfolded relatively through the hinge structure. The hinge structure includes a first rotating shaft, a second rotating shaft, and a torsion member that the first and the second rotating shafts being pivoted thereto, such that the torsion member surrounds and grasps an axial surface of the first rotating shaft and an axial surface of the second rotating shaft respectively. The first rotating shaft has a first actuating portion and a second actuating portion. The second rotating shaft has a third actuating portion and a fourth actuating portion. The torsion member has a first torsion providing portion located on a moving path of the first and the second actuating portions and a second torsion providing portion located on a moving path of the third and the fourth actuating portions.
Abstract:
Methods and systems are provided for opening a refueling door. In one example, a method may include gradually opening the refueling door in proportion to a fuel tank depressurization rate.
Abstract:
A door closer assembly is provided, including a valve regulating an amount of hydraulic fluid that flows through the valve. The amount of hydraulic fluid flowing through the valve controls a force generated by the door closer assembly on a door. A first sensor measures an angular position of the door, and a second sensor measures an angular position of the valve. The angular position of the valve determines the amount of hydraulic fluid flowing through the valve. A controller controls the adjustment of the valve based on the angular position of the door and the angular position of the valve.
Abstract:
A hinge for a door anchored to a wall, the hinge including a fixed element coupled to the wall and a movable element coupled to the door. The fixed and movable elements rotate between an open position and a closed position about a first longitudinal axis. One of the movable and fixed elements includes cam means rotating about the first longitudinal axis, the other of the movable and fixed elements including follower means mutually interacting with the cam means for sliding along a second longitudinal axis substantially perpendicular to the first axis. The follower means includes an elastic counteracting element. The cam means includes a first cam element interacting with the follower means for movement from end-stroke positions to an intermediate position and vice-versa. The cam means further includes a second cam element interacting with the follower means for movement from the intermediate position to the end-stroke positions and vice-versa.
Abstract:
An adjustable snap-acting hinge is provided. The hinge includes a first articulated quadrilateral and a second articulated quadrilateral, which can move on a working plane and share a first lever and a second lever and are provided respectively with a plate for coupling to a first element and with a plate for fixing to a second element. A contrast element is associated with the coupling plate and can be arranged in at least one position for use, which lies between a first position in which the contrast element is arranged at a maximum distance from the point of the first lever, and a second position in which the contrast element is arranged at a minimum distance from the point of the first lever. The hinge also includes locking means for keeping the contrast element in the position for use.
