Abstract: This is a device for supporting an animal clamp (100) fixing a small laboratory animal in a specified position with respect to a testing apparatus (300). A base board (2) is fixed to the testing apparatus (300). An elevating board (4) is raised or lowered by jacks (31, 32) installed between it and base board (2), and a clamp mounting board (8) is tilted by jack (61) and sliding member (62) installed between it and elevating board (4).As a result, the height position and inclination angle of the animal clamp (100) mounted on the clamp mounting board (8) are determined, and they may be finely adjusted by properly manipulating the jacks (31, 32, 61). The animal clamp (100) does not slip off the clamp mounting board (8) because of the clamp slip preventive flange piece (7).

Abstract: Apparatus providing an adjustable height work surface. A work table is cantilevered from posts supported for vertical motion inside columns from a base. A drive connected between the work table and the base changes the height of the work table and is located between the columns and posts. Each post carries a rack that engages with a pinion supported by a column for rotation about a common axis. A rigid shaft interconnects two pinions and prevents relative pinion rotation. A stabilizing structure in each column interacts with the post to maintain engagement between the rack and pinion structure and maintains the work table in a horizontal position during adjustment and use.

Abstract: The table has two telescopable supports (4) each with a flange (22) at the upper end. To the flanges (22) there is screwed fast a tub (6). In the rear part of the tub (6) there is present a cable channel. The table plate (8) is horizontally shiftable on the tub, so that the cable channel is accessible. With an extensible crank (62) over a toothed-belt gear two threaded spindles are synchronously actuated in the supports (4) for the height adjustment. The table is rapidly resolvable into space-saving parts, without its being necessary for the height-adjusting mechanism to be disassembled. The table is convenient to operate.

Abstract: A universal computer support bracket adapted for use in a vehicle, particularly in a train. The bracket includes a channel to be mounted on a vertical surface. Slidably mounted in the channel is one end of a folding table support bracket. Pivotally mounted to the other end of the folding table support bracket is a folding table which may be pivoted between a substantially horizontal support position and a substantially vertical storage position. Mounted on the folding table is a pivot joint assembly on which is mounted a computer support table. The computer support table may thus be tilted to facilitate use of the computer. The invention is thus designed specifically to provide a reliable, sturdy and steady computer support bracket for use in a variety of situations, while recognizing and addressing important space considerations.

Abstract: A computer workstation for supporting and positioning a computer and/or its video display terminal or screen and its keyboard at minimum fatigue locations. The computer and/or the video display terminal can be located at a desired elevations and tilted. The keyboard is supported on a keyboard shelf which can also be positioned at a desired elevation and tilted. The computer table and shelf are located between side wall panels of a frame having racks with slots at different elevations. Both the keyboard shelf and the computer table are pivotally mounted on members which can be positioned in different ones of the slots to select the elevation thereof. A belt connected at one end to the frame extends around a pulley under the computer table so as to support the table. The belt has holes which are engaged by a hook on a handle which is pivotally mounted to the bottom of the table. By pivoting the handle the length of the belt underneath the table can be changed thereby tilting the table.

Adjusting the length of the adjusting rods changes the height of the boards and the angles of the boards with respect to the plane of the horizon so that the height of the desk is adjusted.

Abstract: A table assembly supports a computer terminal and viewing screen, and keyboard, at a central location for optimum use by a number of users. Separate keyboard-supporting and terminal-supporting tables are independently vertically adjustable. Electrical switches on the keyboard-supporting table are actuated to effect operation of electric motors, which in turn rotate lead screws engaging nuts operatively attached to tubes supporting the tables, and thus effect reciprocation of the tables. The terminal-supporting table is pivoted about a horizontal axis so that the tilt thereof may be adjusted, and the keyboard-supporting table is slideable between detented positions to adjust the position of the keyboard with respect to the terminal and screen. At least one larger side panel, and a rear panel and other panels form the base of the assembly and allow it to be readily integrated with office furniture.

Abstract: The elevation and angle of a desk top are independently adjustable with the exertion of a minimum of manual force, thereby facilitating the use of the desk by handicapped or disabled persons. The desk is provided with a torsion bar to substantially ease elevational adjustments and with a parallel lever arm construction which permits such adjustments without changing the angle of the desk top. The height and tilt angle of the desk top are each securely fixed by means of a pair of serrated, interlocking discs which are spring loaded to permit them to be easily locked or unlocked with only a few turns of an adjustment handle. In addition, frictional washers are utilized in conjunction with this spring loading to substantially maintain the position of the desk top even after the discs are unlocked, further facilitating angular and elevational adjustments by persons of impaired physical strength.
