Description

 The proposed bench workbench, designed to work on it mainly by students, for the sake of cheapness of its structure and suitability for students of different height, has instead of a screw a special wedge clamp for workpieces and a device for lifting the entire workbench according to the height of the worker, consisting of along the length of the workbench of stepped protrusions and rearranged along them with the aid of a knuckle shaft of the workbench.

In FIG. 1 is a front view of the workbench; FIG. 2 - its top view; FIG. 3 is a side view; FIG. 4 - top view of the lower part of the workbench; FIG. 5 is the same, front view; FIG. 6 are two kinds of additional clamping.

The table of the proposed workbench for simultaneous work of two persons is composed of two identical parts, connected between; a four crossbars ff (Fig. 2 and 3). Each part of the table is made of horizontal planes j4 and vertical plank- &, connected with each other by bolts / (Fig. 1). The JB space (Figs. 2 and 3) between the boards A of both parts of the table is covered with thin boards and serves to accommodate dies and tools. Akb boards have a series of square holes g, g for the insertion of combs and in one row with them,

Near the right edge of each half of the table, along a one-sided hole or slit e. Under these holes d, e, inside the corner formed by boards A and b, there is a short bar a (Fig. 3), which serves as a front clip for workpieces and guided , with its longitudinal movement, except for boards A and B, bar b. The bar and is provided with holes transversely perpendicular to each other for inserting the combs produced from the top or side of the table with their heads through the slots, d in the boards A h B. The longitudinal movement of the bar to clamp the combs of the product is: wedge, driven or horizontally into the slot d of the vertical plank B, or obliquely into the slot W of the horizontal plank A. To perceive the pressure of the wedge in both cases, the bar a is provided at the end with the corresponding bevels

In the workbench, more dbbavochnye clips M (Fig. 6) are used, in the form of two squares, placed in front of the edge of the table, so that they cover several holes r in the boards A to B; These clamps also have holes in both shelves of the squares. In one square comb you can skip. through its holes and through the holes in the boards A and N B, thus skre

nviTb this square with a workbench, and another square, which itself will serve as a clamp, can be fastened with a bar and with the help of combs, passed through the holes of the square and bar.

To carry out the vertical raising of the table, the workbench is not placed directly on the floor, but on the stand I (Fig. 4 and 5), made in the form of a frame, on the two extreme longitudinal links of which there are stepped projections e which serve to set the feet of the workbench on any pair of steps, and on the middle connection a block C with semicircles, mi depressions TS and S. The legs, including two, are also made in the form of vertically standing frames (Fig. 1 and 3) with horizontal upper and lower links mi O, O v with vertical posts P. bars p, p, in which their necks lie transversely valtp workbench with punched y, y, coming schimis above block C iS stand, and with levers a dipper .X, X at the ends. During rotations, the shaft t, resting successively with its fists y, y into the recesses of the I and III blocks C, will rise or fall, at the same time moving to the right or left along the support I. At the same time, the lower links O , On the frame of the legs of the workbench, are mounted on one or another pair of stepped projections E, as shown in FIG. 5. Thus, the benchtop can take a different height position above the floor.

The subject matter of the invention.

Claims (3)

1. A stollen student workbench, characterized by the use of a front clip in the form of a bar a (Fig. 3), guided by bar b and a board B and provided with two rows perpendicular to each other located openings for the combs passed through the oblong slots in these openings d (Figs. 1 and 2) in boards A to B of the workbench, which bar a is provided on its end face with bevels for inserting wedges into them through the slits in order to move it when clamping the workpiece between the comb on it and the comb on board A. 2. When working at workbench according to claim 1, the device for lifting it according to the height of the worker, is used under the workbench I stand (Fig. 4 and 5), equipped with stepped projections E under the workbench feet and pad C with recesses C and W to support their fist walls are y, y, fastened to the shaft m (Fig. 1), whose supports are placed in bars p connecting the legs of the workbench, and which has been replaced with handles X for its rotation. 3. In the workbench of claim 1, the use of additional clamps M (Fig. B) in the form of two squares overlaid on boards A and B of the workbench and fastened one with them and the other with a bar and dies passed through the holes in the clamps. and in these boards.
