Abstract

The invention relates to furniture that can be used in vocational training, public education and in the preparation of workers in production as a universal training table. The purpose of the invention is to expand the operational capabilities and simplify the design. The training table contains a frame made of perforated racks, along which perforated rails and slats for installation of instruments move and fix in vertical and horizontal directions. The frame is mounted on a supporting base with the possibility of rotation and fixation in horizontal and vertical positions. To ensure stability, the frame is fitted with a counterweight, fixed to the lower frame cross member. 3 hp f-ly, 2 ill.

Description

The invention relates to training devices and can be used in vocational education & as a universal training table for conducting occupational training, special, general technical and general educational subjects in the preparation of specialists in electrical and radio installation profile.

A training table is known, comprising a tabletop mounted on a support base and a device for accommodating tutorials, connected to the support base by connecting elements with the possibility of covering the tabletop along the perimeter and being movable relative to it in a vertical direction to change the height of the device.

 The disadvantages of this device are large dimensions, low operational capabilities, which makes it difficult to use for classes in general education classes, the need for storage for teaching aids.

The purpose of the invention is to expand the operational capabilities and simplify the design.

Figure 1 shows the training table with a vertical frame; 2 - the same, with the horizontal position of the frame.

The training table contains a tabletop 1, mounted on a support base 2 with hollow legs 3 and 4. On the base 2 using perforated axles 5, there are perforated stands 6, 7. frames, on which brackets 8 are fixed to fix the posts b, 7 in vertical and horizontal position x through pins (not shown). On the uprights 6, 7, the frames are mounted with the possibility of moving in the vertical direction and fixing with bolts and thumbs (not shown) at an arbitrary distance from each other, vertical perforated perekladl

The rails 9, 10, 11. Along the perforated rails 9, 10, 11, vertical perforated rails can be fixed in the horizontal direction and fixed with bolts at an arbitrary distance from each other. Inside the rails, the nuts move freely in the vertical and horizontal plane (not shown). At the lower ends of the uprights 6, 7 fixed counterweight 12, made of a metal plate. On the leg 3 of the support base there are connectors 13, 14, 15 for connecting the power supply and electrical installation circuits. Electrical communications 16 are located in the hollow legs of the table.

The training table is used as follows.

For laboratory work and industrial training on electrical and radio installation specialty, the frame is rotated into a vertical position and fixed in this position by pin-coupling of the bracket 8 with the leg 4. On the racks 6, 7 the required number of horizontal and vertical perforated crossbars and rails fitted with flat four-corners are fastened nuts for securing training devices, the distance between which is freely adjustable. The assembled electrical circuits are connected to connectors 13-15, -. ...; -.

For occupations in general educational, general technical and special disciplines, the frame is placed in a horizontal position after removing vertical slats and horizontal 10, 11 crossbars. In such a position, the frame is fixed by the pin connection of the clips 8 with the table base. A removable tool can be attached to the counterweight for preparatory operations. .

Standard training tables can be used to make the table and

commercially available perforated steel in the form of strips, angles and channels.

Claims (4)

Claims. 1. A training table containing a centenary mounted on a supporting base: tsu and device for placing tutorials, associated with the supporting base of the connection elements with the possibility of covering the worktop along the perimeter and the ability to move relative to it to vertical direction to change the height of the device, so that with the aim of expanding the operational capabilities and simplifying the design, the device for placing teaching aids are made in the form of a frame hinged in the middle part of the lateral sides of the supporting base with the help of semi-axes with the possibility of rotation and fixation in the vertical and horizontal positions. 2. The table is no nJ, which means that the frame of the device for placement of teaching aids is made along the perforated contour and is equipped with perforated removable crossbars with attachment points on the frame uprights. 3. The table according to claim 1, in accordance with the fact that the supporting base has internal cavities for the placement of electrical communications. connected to connectors on the base. 4. The table according to claim 1, which differs from the fact that the frame of the device for placing teaching materials is equipped with a counterweight, which is mounted on the lower longitudinal side of the frame. 9 W 11 ill
