Abstract:
A device for slowing the movement of a drawer or similar movable member, having releasable locking means A device (15) for slowing the movement of a drawer (2) urged by unidirectional thrust means (4), including a casing (17) fixable to a structure (S) and defining a chamber (18) filled with a viscous fluid, and a rotor (31). The rotor (31) includes a disc portion (32) and a shaft portion (33) protruding through the lid (21) of the casing (17) in such a way as it can be associated with the door (2). The base surface (23a) of the chamber (18) has a recess (51) operable to house a pivotable arm (52). The arm (52) has a pin portion (54) protruding into the chamber (18). The lower surface (62) of the disc portion (32) of the rotor (31) has a groove (70) for engaging the pin portion (54) of the arm (52). At one end (73), the groove (70) has a cam (76) dividing it into a return path (75) and a forward path (74) for the pin portion (54) so as to define a locking position for the rotor (31) in cooperation with the thrust means (4).
Abstract:
A sliding assisting device assists a movable body to move between a drawn-in position and a drawn-out position relative a main body. The sliding assisting device includes a unit main body provided on one of the main body and the movable body, and having a slider, a lock member, and a spring member; and an operating member provided on the other of the main body and the movable body. When the movable body is drawn out to a mid-course position from the drawn-in position or drawn-out position, the operating member displaces the lock member from a locked position to an unlocked position, so that the movable body slides from the mid-course position to the drawn-out position or drawn-in position by the spring member.

Abstract:
A door opening and closing device having a rotational mechanism configured to switch a door between a closed position and an open position relative to a base member. The rotational mechanism has a supporting arm integral with the door; a sector gear portion provided on the arm; a rotating gear disposed on the arm at essentially a center of the arc of the sector gear; a first rack portion on the base member and configured to engage the sector gear; and a second rack portion on the base member. The second rack is essentially parallel to the first rack portion and separated by predetermined distance therefrom, the second rack being configured to engage the rotating gear.
Abstract:
A hinge assembly rotationally connecting two components includes at least a shaft coupled to one of the components and a tubular member connected to the other component and a defining an annular space around said shaft. A viscous damping fluid is disposed in said space and provides a damping force resisting relative rotation between the two components. A second tubular member is also provided that is connected to the shaft and is arranged axially around the first tubular member. In this latter configuration, static and dynamic frictional forces are generated between the tubular members that resist rotation between the components as well.
Abstract:
A container having a controlled-opening lid includes a container body with an open end providing access to an interior space configured and dimensioned for receiving user-supplied contents, and a lid member configured and dimensioned to cover the open end of the container body when in a first position and permit access to the interior space when in a second position. A hinge is configured to move the lid member from the first position to the second position, the hinge including at least one damping mechanism for damping a biasing force provided by the hinge when the lid member moves from the first position to the second position. The container may be a beverage container or a physician's desk container for storing medical implements.
Abstract:
A non-contact apparatus removes translational energy (slows movement) of a first magnetic assembly when it is moved through the magnetic field of a second magnet. The first magnetic assembly contains a magnet that can rotate, such as a diametrically magnetized cylindrical magnet in a cylindrical cavity. Rotation of the first magnet does work against a predetermined drag. The apparatus also forms a non-contact magnetic coupling that holds a predetermined relative position. The apparatus can be used as a door catch that slows down and quietly stops a door at a predetermined
Abstract:
A braking apparatus has a main body for connection to one of a frame and a closure member mounted on the frame to undergo linear reciprocating movement between open and closed positions of the closure member. A tubular shaft is mounted in a main body for undergoing rotation. A resistance member is rotatably mounted on the tubular shaft and is disposed in an interior space of the main body containing a braking fluid. A spiral rod for connection to the other of the frame and the closure member is screw-threadably engaged with the tubular shaft so that the tubular shaft undergoes rotation when the spiral rod and the tubular shaft are relatively moved in an axial direction of the spiral rod. When the closure member undergoes linear reciprocating movement, the main body or spiral rod relatively moves in the axial direction of the spiral rod, the tubular shaft and the resistance member undergo rotational movement, and the resistance member receives a resistance of the braking fluid so that the tubular shaft rotates under a braking force of the braking fluid and reduces a movement speed of the closure member.
Abstract:
A cover opening and closing mechanism switches a cover body on a corresponding surface of a main body between a closed position for closing the corresponding surface and an open position for opening the same. The cover opening and closing mechanism includes a forcing device for always urging the cover body toward the closed position; a push button; a switching device having a cam facing the button, an acceleration gear engaging a gear part provided on the cover body, and a striker; and a latch device for locking the striker in the open position of the cover body and releasing the lock when the button is pushed. The switching device switches the cover body from the closed position to the open position against a force of the forcing device.
Abstract:
The clutch includes a drive disk, a follower disk and a brake disk. When current flows, the follower disk is connected with the drive disk to transmit a power from a driving unit to a door-opening/closing mechanism. When no current flows, the follower disk is separated from the drive disk to cut off the power transmission from the driving unit to the door-opening/closing mechanism. In a state that the drive disk and the follower disk are separated from each other, the brake disk is connected to the follower disk to brake the door-opening/closing mechanism in the opening direction of the door, and to allow the door-opening/closing mechanism to move in the closing direction of the door.
