Abstract: A card elevating/lowering device for use with cards may include a card storage part in which the cards are stacked and accommodated, and an elevating/lowering mechanism by which the cards accommodated in the card storage part are elevated and lowered. The elevating/lowering mechanism may be provided with a placing table on which the cards accommodated in the card storage part are placed and an urging member which urges the placing table in an upper direction, and a spring constant of the urging member may be substantially equal to a weight per unit thickness of the card.

Abstract: A safety stop is provided for stopping a movable member having at least one set of opposed wheels for gripping a rail. The stop has a track on each of opposite sides forming a wedge shape of a narrow end progressively widening to a wide end in a direction of travel of the movable member. With the opposed wheels of the movable member respectively at opposite sides of the wedge shape member, the tracks of the wedge shape member engage and impart a spreading strain to the opposed wheels as the movable member moves in the direction of travel. The opposed wheels of the movable member comprise a deformable material to absorb the kinetic energy of the movable member. The tracks of the stop additionally may have undulating features comprising concave and convex surfaces in the direction of motion.

Abstract: A device for storing goods, in particular vehicles, the goods being stored on at least one platform and the platform being guided on guides over a traverse path and a guide for traverse being provided. By the cooperation of the safety device arranged on the guide or device and the platform the platform is protected against undesired movement. The safety device is indicated by at least one locking unit and at least one locking element. The locking unit is rotatable and supported in such a way that the center of gravity of the locking unit is arranged off-center.

Abstract: A lift having a safety lock system includes a mast that may be supported by a base, and a frame that can be lifted or lowered along the mast. The safety lock system includes a first support beam that is located adjacent to the mast and a second support beam that is located opposite the first support beam relative to the mast. The safety lock system also includes a first lock and a second lock. Each of the first lock and the second lock are operable between a plurality of locked positions and an unlocked position. In the locked position, the first lock is engaged with the first support beam to lock the lift frame to the first support beam, and the second lock is engaged with the second support beam to lock the lift frame to the second support beam. Each of the first lock and the second lock can be placed in the unlocked position, wherein the lift frame can be freely lifted or lowered relative to the mast.

Abstract: A carrying track for a building, which includes a building including a plurality of floors, a track extending from a lower floor of the building to a floor above the lower floor, the track structurally forming part of the floors and part of an outside surface of the building, wherein the track includes two vertical halves with a gap formed between, the gap being exposed to the outside surface of the building and extending inwards from the outside surface.

Abstract: In an elevating mechanism 14 where an elevating mechanism 17 carried so as to rise and fall along a fixed surface 16 is moved up and down through a suspension member 18, a braking mechanism 18 is born by the elevating mechanism 17 so as to pivot vertically. A tensile spring 32 is provided on the braking mechanism 31, for pivotally urging it to the direction close to the fixed surface 16, while the suspension member 18 is connected to the braking mechanism 31, for pulling the braking mechanism 31 in the direction apart from the fixed surface 16 due to the weight of the elevating mechanism 17, in opposition to the tensile spring 32. When the suspension member 18 is cut off, then the braking mechanism 31 comes into contact with and digs into the fixed surface 16 by action of the tensile spring 32, so that the elevating mechanism 17 can be stopped from falling.

Abstract: The present invention comprises a safety lock device for an automobile lift having a lifting carriage slidably connected to a post and supported by a flexible lifting member, such as a chain or cable. The safety lock device comprises a ratchet lock mechanism which prevents inadvertent lowering of the carriage and a fail-safe mechanism which automatically engages the ratchet lock in the event that the flexible lifting member should fail or otherwise become slack while the ratchet lock is disengaged. The ratchet lock mechanism includes a ratchet track connected to the post and a ratchet pawl connected to the lifting carriage. When the ratchet pawl is in the track engaging position, the pawl allows the lifting carriage to move upward but prevents it from moving downward. The pawl is moved into the release position by a release lever pivotally connected to the ratchet pawl.

Abstract: An apparatus for stacking sheets has a frame defining a stacking station, a conveyor for delivering the sheets continuously one after the other at a predetermined upper level in a transport direction to the station, and a platform vertically displaceable in the stacking station between the upper level and the lower level. The antidrop protector includes a vertically extending rack fixed on the frame, a lever pivoted on the platform adjacent the rack and having a pair of arms one of which is connected to a lift cable, a stop on the other of the lever arms engageable in the rack, and a spring braced between the platform and the lever. The cable is connected to a drive that tensions the cable, displaces the platform vertically, and rotates the lever in one rotational sense. The spring urges the lever in the opposite sense so that when the cable is detensioned the spring urges the stop into the rack and vertically arrests the platform.

Abstract: A safety device for a platform cable hoist within a latticework tower including a plurality of skid members which are flexed inwardly when there is tension from a lift cable. Brake members are secured to the skid members and, in the event the cable fails, the skid members deflect outwardly so that the brake members, which have hook portions at their upper ends, engage transverse braces of the tower. Between the hook portions and the skid members, the brake members are formed with an energy absorbing portion which absorbs kinetic energy from the falling platform to slow and stop its descent.

Abstract: Provided is an elevator safety apparatus for use by an elevator to prevent the elevator from free-falling in emergency conditions. The elevator safety apparatus is also capable of cutting off the power to the elevator's motor and triggering a beeper when it stops the elevator. In normal conditions of the elevator, a stopping bar is suspended due to a weight such that the engaging head of the stopping bar maintains a distance from stopping teeth provided on the guide rail that guides the elevator. And in emergency conditions when the elevator is subject to free-falling, the engaging head of the stopping bar is moved upwards by elastic force due to the loss of the gravitational force exerted by the weight during the free-falling, thereby coming into engagement with one of the stopping teeth and thus stopping the elevator. The elevator safety apparatus is simple in structure, having fewer movable parts so that it is more reliable.

Abstract: A reinforced column for a lifting apparatus which includes an elongated outer shell member having a rectilinear cross-section. One side of the outer shell member has an elongated aperture therethrough, allowing access to an interior portion of the column. Interior of the outer shell, a pair of opposed elongated guide rails are positioned adjacent the elongated aperture. An elongated inner shell is simultaneously attached to selected portions of the guide rails and held at predetermined spaced relationships to the interior surfaces of the outer shell. The elongated inner shell is arrayed for providing a pathway for a carriage member of said lifting apparatus to travel therein.
