Abstract:
A method for opening a door on a storage bin is provided, where the storage bin includes a door pivoted to the storage bin for movement between open and closed positions, and a biasing device operably connected to the storage bin and the door for biasing the door as the door nears the open and closed positions. The biasing device includes a spring and a T-shaped shifting anchor connected to the spring that translates and changes a torque arm of a linear spring as the door is moved so that the spring creates a force sufficient to close the door during a last portion of door closure movement and so that the spring creates a force sufficient to open the door during a last portion of door opening movement.
Abstract:
A magneto-rheological clutch assembly for use in an electromechanical system. The clutch assembly includes a motor having a shaft that is coupled to a magneto-rheological clutch. There is also included a gear plate that is attached to the clutch, as well as being connected to a contact plate and pinion gear. The pinion gear engages a corresponding connection of a power operator system. The magneto-rheological clutch prevents damage to the motor power operator system and panel by simulating a slipping condition when a load exceeding a specified tolerance is applied to the panel.
Abstract:
A front lid opening and closing assist which enables an easy and safe operation of opening and closing a front lid of a keyboard instrument. A buffer in the front lid opening and closing assist has a first damping mechanism for damping the front lid when pivoted from a neutral position to an open position, and a second damping mechanism for damping the front lid when pivoted from the neutral position to a closed position. When the front lid is pivoted beyond the neutral position, it spontaneously pivots toward the open or closed position by its own weight. However, this motion is damped by the first and second damping mechanisms, which results in a slowed pivot motion of the front lid. As a result, a user can safely open or close the front lid relative to a back lid, with only minimal force for supporting the front lid.
Abstract:
A door closer includes casing fixedly fastened to a door frame, a hydraulic cylinder installed in the casing and holding a hydraulic fluid, a coupling block installed in one end of the hydraulic cylinder, the coupling block having a pivot shaft connected to a door, and a reciprocating mechanism coupled to the coupling block, fluid velocity regulating valves installed in the casing and controlled to adjust the velocity of the hydraulic fluid flowing in the casing, the reciprocating mechanism including a double-threaded adjustment rod for adjusting the spring power of compression springs thereof.
Abstract:
The present invention provides a damping mechanism capable of varying the moving speed of an openable door or the like in stages as necessary. Such damping mechanism includes a damping body (1) installed with a damper mechanism and allowing a rotative shaft (3) to protrude therefrom; a plurality of pinions (4, 5) provided on the rotative shaft (3) and each having a different diameter from one another; and a rack member (2) including a plurality of racks (7, 8) respectively engaging with the pinions (4, 5).
Abstract:
A control device for a door closer is arranged to control flow of pressure medium within a body part of the door closer and comprises an adjustment member supported by threads on the body part of the door closer, and in cooperation therewith, a separate substantially hollow control member, which is arranged to restrict the flow of the pressure medium when necessary. Turning of the adjustment member with respect to the body part of the door closer brings about movement of the control member in the axial direction of the control device for providing the desired control. The control member is arranged to be attached to the adjustment member in the radial direction so that movement of the control member with respect to the adjustment member in the axial direction is prevented.
Abstract:
A door assembly which includes a door that slides open and closed to alternatively expose and cover components of a computer system. The door assembly includes a rack and pinion system that prevents racking of the door. The non-racking feature allows for the door to be wider than prior art doors such that more components may be easily accessed by a computer user. The door assembly also includes a spring assembly for automatically closing the door, a dampener for moderating the movement of the door, and a latching mechanism that holds the door open. In one embodiment the latch mechanism is a push-push latch and the spring of the spring assembly is a constant force spring.
Abstract:
The folding doors 100 includes of a first door panel 150 and a second door panel 110, the first door panel 150 being attached to the door opening portion of the wall rotatively by a pin 150. The second door panel 110 is attached to the first door panel 150 by a hinge 4. A guiding device 120 is mounted on the upper portion of the second door panel 110. The guiding device 120 holds a slider 122 and a rotary damper 200 for damping the rotation of the axis holding the slider. The slider 122 slides without rotating inside the guiding rail mounted on the upper portion of the door opening portion. The second door panel 110 rotates by opening/closing action, so by damping this relative rotation with the rotary damper 200, the folding doors could be closed quietly.
Abstract:
A rotation deceleration device used for a sanitary cleaning device which includes a toilet seat and a toilet cover and is attached to a toilet bowl, thereby injecting warm water in the toilet bowl. The rotation deceleration device includes a cylinder having a hydraulic chamber filled with a control oil; a rotation shaft inserted through the cylinder; a control wall radially projected from the rotation shaft to divide the hydraulic chamber into at least two sub chambers; a control valve provided between the control wall and an inner surface of the cylinder. The control valve has a closing wall opposed to a side surface of the control wall so as to be attachable thereto and also has an engaging member opposed to the other side of the control wall so as to be engageable therewith in accordance with the rotation of the rotation shaft. The control valve is formed of a material which has a higher coefficient of thermal expansion than that of a material forming the control wall and the cylinder.
Abstract:
A door closer (20) is attachable to a door (24) and includes a cylinder (36) which forms a chamber (44) in which a piston element (50) is movable to move fluid from the chamber to a reservoir (82) upon opening of the door. After the door (24) has been opened to a position, for example, of ninety-five to one hundred degrees, continued opening of the door causes the fluid to be compressed within the chamber (44) and to be directed only through a back check valve (95) to the reservoir (82). This results in the development of an adjustable "back check" condition to provide a counterforce to the continued opening of the door. A passageway (150) is formed in cylinder (36) to allow fluid to flow relatively freely from chamber (44) to reservoir (82) until an inward end (56) of piston element (50) has travelled a prescribed distance "x." This prescribed distance of travel represents the opening of door (24) to ninety-five to one hundred degrees from the door's normally closed position.
