Abstract: The invention provides a relatively simple and inexpensive power-assisted movable rack system, movement of which is controlled by an operator. The movable rack system comprises a plurality of movable racks, each of which includes a plurality of wheels, a DC motor turning forward or backward and reciprocating the movable rack, a pair of direction switches provided at opposite positions in moving directions of the movable rack, and an actuating circuit rotating the DC motor in one direction during the operation of one of the direction switches and rotating the DC motor in an opposite direction during the operation of the other direction switch. The DC motor applies dynamic braking force, so that movable racks can be stopped with a short braking distance.

Abstract: A storage system with ambience conditioning facilities includes a desiccator for removing moisture from air and promoting convection, thereby maintaining articles stored therein in an optimum state for a long period of time. The environment maintained has stable humidity, is free of contaminants and suppresses aging of articles by humidity and microbes.

Abstract: An attachment apparatus is arranged to be suspended from an overhead travelling crane or other similar means and is employed for a cargo handling operation, for example, unloading an article placed on a shelf or rack. The attachment apparatus includes a frame section adapted to be suspended from a hook attached to a crane, a fork section movably mounted on the frame section and adapted to scoope up an article, and a driving section for driving the fork section. The frame section has a ceiling member equipped with a suspension member, the mounting position of the suspension member being adjustable. The fork section has a pair of fork members, the distance therebetween being adjustable.

Abstract: A movable storage cabinet includes a plurality of saddles, in the form of inverted channels, and each provided with holes in its opposite lateral sides which receive the shafts of wheels. The saddles extend in the direction of depth of the cabinet, and the front and rear ends of adjacent saddles are connected together by a connection member, thus forming an underframe of the cabinet.

Abstract: A sliding door is provided which is suitable for use as a heavy door for vaults in banks. The door is provided at its bottom with driving wheels adapted to be rotated manually by means of a handle, through a suitable power transmitting means, thereby to move the door along a rail. The power transmitting means may incorporate a suitable reduction means so that the door may be moved with a reduced force and, accordingly, at a lower speed. Means are provided for locking the door in the closed state.

Abstract: A door assembly including a door associated with a guide which is disposed in an orientation perpendicular to the plane of a door opening formed in a wall, and a guide follower mounted on the door to run along the guide. In one embodiment the guide follower is rotatably driven by the rotation of a handle mounted on the door through a transmission. In another embodiment, the door may be manually pushed or pulled along the guide.

Abstract: Disclosed is a mobile rack system intended for an efficient use of a limited space of store house and the like for storing books and other goods, having a plurality of mobile racks adapted to run along rails laid on the floor of the store house. The system incorporates at least one human-power driven pedal-actuated driving source. The driving source may be provided for each of the mobile racks or may be provided independently of the mobile racks for running along separate rails. The driving source has a pair of pedals, at least a pair of driving wheels, speed reduction transmitting means between the pedals and the driving wheels, and a saddle for the operator to sit on, the position of which being switchable in accordance with the direction of movement of the rack or the tractor.Braking means are provided for preventing the mobile racks from moving unintentionally, thereby to avoid accidents due to the collision of racks.

Abstract: Disclosed is a device for anchoring a movable box-shaped shelf assembly of the type wherein the assembly is supported by wheels which in turn ride on parallel rails laid on a floor and a handwheel is attached to one side wall of the assembly and is drivingly coupled through a reduction gear to a shaft of the wheels so that upon rotation of the handwheel, the shelf assembly may be moved along the rails in either direction.

Abstract: A manually movable wheeled storage rack or the like is disclosed which may be moved along a pair of rails when an operator rotates a handwheel attached to one side wall of the storage rack or the like. The storage rack or the like is further provided with a locking device so as to hold the storage rack or the like in a desired position and a safety device so that when a buffer plate of the safety device hits an operator or worker in the passage between the adjacent storage racks or the like as one of them starts to move by an accident, the safety device immediately locks the wheel, whereupon the operator or worker may be prevented from being sandwiched between the storage racks.
