Abstract: An accessory suspension device for an existing binder is formed by an angle strip having slides which can be pulled out so as to project from opposite ends of the spine to suspend the binder. The device fits on the rings of the ring mechanism of the binder and acts to support the ring portions which actually carry the sheets of paper contained in the binder when the binder is suspended by the device.

Abstract: A ring binder device for a file serves to hold documents and to provide a means whereby the file can be suspended spine uppermost between two carrier rails, the device having slidemounted suspender members which can be set, by moving their slide mountings, to protrude beyond the edges of the file ready for resting on the rails, and the slide mountings incorporating locks operative when the suspender members are protruding to prevent the binder opening.

Abstract: A ring binder has a ring mechanism on the inside of the binder spine and two boards covering the inside surfaces of the binder covers which are hinged to the spine, the boards forming extensions which extend the covers inwardly close to the rings when the binder is open to provide flat writing supports, and the binder has straps interconnecting the covers and supporting the extensions which extend the covers inwardly.

Abstract: Automobile wheel with wire spokes accessible through a recess in the outer spoke band adjacent the drop center of the rim, thus permitting use of tubeless tires.

Abstract: A ring binder device for a file serves to hold documents and to provide a means whereby the file can be suspended spine uppermost between two carrier rails, the device having slide-mounted suspender members which can be set, by moving their slide mountings, to protrude beyond the edges of the file ready for resting on the rails, and the slide mountings incorporating locks operative when the suspender members are protruding to prevent the binder opening.

Abstract: A file has a pin-type document binding mechanism formed by two co-operating binding elements which can be united to close and lock the binding and so secure documents therein, and the binding has two captive, slideable brackets which can be pulled apart until they protrude from either end of the spine of the file to enable the file to be suspended spine-uppermost between rails of a file suspension system.

Abstract: A frame structure for furniture, especially table frame structure, according to which a first rigid support structure supports a pivotal support structure which is pivotally connected to the first rigid support structure for selective movement along a vertical plane from a first position of use in which it forms an upwardly directed extension of the first rigid support structure to a second position of use in which the pivotal support structure is folded downwardly at least approximately onto the first rigid support structure. The frame structure furthermore comprises a second rigid support structure which is pivotally supported by and extends upwardly from the pivotal support structure while forming with the latter a parallelogram linkage system, the pivotal support structure being adapted selectively to be locked to the second rigid support structure in the first position of use of the pivotal support structure.
