Abstract: A caster assembly that can be used with furniture to support the furniture and to make the furniture mobile. The caster assembly has a housing with a stem that extends upwardly to be attached to the particular piece of furniture. Within the housing is a plurality of spherical rollers that are supported within the housing so as to be rotatable about their center points and therefore can rotate in any direction as the furniture is moved. In the preferred embodiment, there are three spherical rollers that are all equidistant from the center line or longitudinal axis of the stem so that the weight of the furniture that bears down upon the stem is supported equally by the spherical rollers contacting the floor. As a further feature, a glide cup is provided that can be readily attached and detached from the bottom of the housing and, whet attached, the glide cup covers the spherical rollers and presents a flat, planar surface that contacts the floor.

Abstract: A protective member, preferably an extruded plastic is used to enclose, at least partially, a component of a bed frame so as to provide protection against inadvertent injury to a user striking the otherwise sharp edges of the component. The components are normally a side rail and a center rail and the protective member is snapped fitted to that component by the presence of curved lips that at least partially encircle the external edges of the component. There are also ribs formed in the protective member and which position the protective member a predetermined distance away from the particular component. In the case of the center rail, the protective member is spaced away from the upper surface of the center rail so as to compensate for the lower position of that surface with respect to the head and foot cross members so that a box spring resting upon the side rails and the center rail is supported evenly and does not bow at its center due to a spatial difference between the center rail and the cross members.

Abstract: A molded plug is provided that is used to lock structural members together where those members are joined together by the interengagement of a standoff rivet and a keyhole slot. In the normal interengagement of such structural members, a standoff rivet of one of the structural members is inserted into an enlarged portion of a keyhole slot on the other structural member and the structural members are moved relative to each other in order to slide the standoff rivet into the narrowed portion of the keyhole slot. When so positioned, the plug is inserted and locked into position within the enlarged portion of the keyhole slot and thus prevents any relative movement between the structural members to insure that the standoff rivet cannot again become aligned with the enlarged portion of the keyhole slot where inadvertent disengagement of the structural member could occur.

Abstract: A protective guard is disclosed that is particularly adapted for use with a bed frame. The guard is adapted to fit over an existing leg of the bed frame and has a specially shaped opening in the upper surface into which the leg of the bed frame can fit. A caster assembly has an upstanding stem that passes the existing leg in the leg structure and holds the protective guard in position affixed to the bed frame. The protective guard is shaped in a variety of configurations and surface markings so as to be adapted to fit the décor of the room in which it is used. In addition, the overall shape of the protective guard covers the leg of the bed frame to provide protection against injury from the inadvertent bumping of the bed frame leg by persons walking or standing near the bed frame. In one embodiment, the protective guard is an integrated shield and a caster assembly that is affixed to the leg of the bed frame and provides a protective plastic covering for the caster assembly as well as the leg.

Abstract: The present invention is directed to an optical device and method for adjustably magnifying the visual displays on the screen of a computer monitor or the like, the invention comprising an adjustable arm for supporting at least one magnifying lens in front of the monitor, which adjustable arm is attached to a stationary support independent of an operator's body. The adjustable arm for supporting the magnifying lens between the viewer of the screen and the screen of the computer monitor is movable in a substantially axial and vertical direction with respect to the computer screen, so that the magnifying lens can be adjustably positioning to a desired position relative to said screen. The invention is especially useful for helping presbyopic computer operators to more clearly see the visual displays on the screen. A second embodiment of the invention further comprises a second lens that can be used to view a document held next to the monitor.

Abstract: An eyewear loupe which is adaptable to various types of eyewear frame and provides a sub-area of magnification. The loupe is easily removed from an eyewear frame and reattached. The loupe can be worn on either side of an eyewear frame.
