摘要:
A translation table that has a spring biased dovetail bearing. The table includes a first element with a dovetail groove and a second element with a dovetail bearing located in the groove. The table further includes one or more springs that press the bearing into the groove. The spring force may be selected to eliminate lateral movement between the first and second elements while minimizing the friction of the bearing. The spring force may be varied by a screw(s) that engages the spring(s).

A table (10) for an operating room providing a cantilevered over-patient instrument surface (12) that can be swiveled away from the operating field without moving the base (20) of the table. The instrument surface may have two levels (38, 40) with a variable degree of overlap between the levels to form an instrument surface of a desired area. The instrument surface may further have a curved edge (44) so that the proximity of the instrument surface to the operating field does not change as the instrument surface is rotated relative to its base. A sterile drape (60) covers the instrument surface and extends downward to be attached around the table support structure (14). The drape may be formed of two sections (62, 64) having overlapping tail portions (68, 70, 72, 74). The base may include a footpad (24) for a nurse (26) working at the table. Spring-loaded rollers (30) facilitate movement of the table across the floor (34) while withdrawing under the weight of a nurse standing on the footpad to provide unmoving contact between the base and the floor when the table is in use.

The invention includes a method of marketing food items in a retail store, the method including displaying breakfast and lunch foods on a counter, where the counter is configured to be rotatable in the horizontal plane. During a period of hours of a day when breakfast foods are in demand by customers, positioning the counter such that breakfast foods are most proximate to an entrance to the retail store and lunch foods are least proximate to the entrance to the retail store. At about the end of the period of hours of the day when breakfast foods are in demand by customers, rotating the counter about 180 degrees in the horizontal plane such that the lunch foods are positioned most proximate to the entrance to the retail store and breakfast foods are positioned least proximate to the entrance to the retail store.

A connection device for tables includes a shaft on which a first part and a second part are respectively mounted thereon. The two parts are pivotally connected with each other and have their own connection shafts. Each of the connection shafts is connected to a table top so that the two table tops are pivotable about the shaft as desired.

A keyboard tray apparatus comprising an articulating arm coupled to a table at one end and a keyboard tray at the other. The keyboard tray apparatus provides: (a) a hook and slot system for removably coupling the keyboard tray to an articulating arm with ease; (b) a reversible mouse pad capable of being removably coupled with a spring-biased ball detent to either side of a keyboard tray; and (c) a keyboard tray having a forward two-sleeve set and a rear two-sleeve set and capable of mating with a mouse pad in a forward position or in a rear position.

The Sliding Tabletop consists of a tabletop made of wood which has sliding mechanisms attached to the bottom side. The sliding mechanism attaches the tabletop to the table frame. The sliding mechanisms are metal or wooden drawer type slides that attach to the tabletop and table frame with screws or glue and allow the tabletop to slide while the frame remains fixed in place. When in the closed position, the tabletop is centered over the frame. When slid open, the top extends to the edge of the frame exposing any storage space within the frame. The sliding mechanisms do not allow the tabletop to extend past the table frame. This prevents the possibility of the tabletop sliding all the way off the table frame and onto the floor. The sliders also support the tabletop when slid open.

A linear table includes a slide plate, a base, and pair of bearing assemblies. Each bearing assembly has an inner and outer bearing way, and a rolling element located between the bearing ways. The bearing ways are securely fixed to the slide plate and the base. A precision parallel device and preload fixture are used to align the bearing ways and provide a proper preload on the bearing assemblies without integral preload screws or other preload method, or integral bearing locating shoulders or other such geometry.

A machine tool comprises a first travelling assembly (10) which carries in its turn a second travelling assembly (22). The first assembly (10) is adapted to position the second assembly (22) in a relatively wide space (S1) and with movements at relatively low speeds and accelerations. The second assembly (22) carries in its turn a tool which is provided with actuators for positioning the tool in a relatively narrow space (S2) and with movements at relatively high speeds and accelerations. The machine includes means for controlling the movements of the two assemblies (10, 22) which are so arranged to obtain s global movement of the tool without solutions of continuity in all the space of movement (S1) of the first assembly (10). The invention also relates to a manipulator device which can be used independently or be installed as a second assembly (22) on a travelling structure Or a machine tool.

The invention is directed to a tray which includes a base having an upwardly opening open-ended groove and a member slidable in the groove for limited right-to-left and left-to-right movements in a horizontal plane. Upper surfaces of the base and the slidable member lie substantially in a common plane such that at least two input devices, such as a keyboard and a mouse, can be supported thereon on substantially the same horizontal plane.
