Description

STUDENT'S TABLE FOR PHYSICS STUDY 1 The utility model relates to devices for satisfying a person’s vital needs and can be used as a student’s desk for a physics classroom. One of the problems arising at school when it is equipped with specialized furniture in physics classrooms is that in conditions differentiated for classes with diverse profiles, the same standard equipment is most often available. For one school day, from six to twelve classes attend a physical office, which greatly complicates the conduct of a variable school physical experiment. Known student table, the developers of which are Skvirchak A.L., Lantsman P.Sh., Derbyshev A.V. and others (RU PMPO Utility models 1997, .№3), containing a fixed tabletop, two pairs of legs, horizontal supports and upper crossbars under the tabletop. When conducting a school physical experiment, the design of this table has limited capabilities that do not allow to increase its working surface. There are no built-in devices in the table that facilitate the experiment and special shelves for using this sample with a computer. Kvazar - School Furniture Limited Liability Company also offers several types of tables (RU PMPO Utility Models 1999, No. 11) containing a tabletop and a frame made of bent metal pipes. However, their use with a computer is difficult. As a prototype of the claimed technical solution, a table was selected containing a tabletop and a shelf, as well as two metal frames, on one of which the tabletop is fixedly mounted, and on the other a shelf with the possibility of vertical movement relative to the tabletop (A. Skvirchak, P. Lantsman. , Derbyshev A.V. and other RU PMPO Utility models 1998, No. 2). MKI: A 47 at 41/00

The disadvantages of the known table are due to the following.

This table cannot be transformed to an ordinary child's table; the shape of the metal frame of the shelf does not allow it to be lowered to create the necessary horizontal work surface. It lacks special devices that facilitate the conduct of a school physical experiment.

The problem solved by the claimed utility model is to expand the functionality of the table as an apprenticeship for the physics cabinet.

This problem is solved in that at the table containing the tabletop and the shelf, as well as two metal frames on one of which the tabletop is fixedly mounted, and on the other the shelf is vertically moving relative to the tabletop, made with the possibility of contact with the tabletop with the formation of a single working horizontal surface.

In addition, for a more successful implementation of a variable school physical experiment:

- In the internal cavity of the front pillars of the countertop frame there are spring-loaded retractable stands with clamps;

- the frame of the movable shelf has a solid back panel;

-the shelf is equipped with a removable metal bar curved along its half-perimeter;

- a removable reclining shelf with a stop and a limiter is attached to the side racks of the tabletop.

The utility model is illustrated by photographs and drawings.

The figure 1 shows a photograph of the inventive table with a raised movable shelf and retracted tripods, a removable reclining shelf for the computer system unit is transferred to the working

Figure 2 shows a table with the shelf lowered, extended tripods and a folding shelf for the system unit, which is in an upright position. Equipping a table with extendable tripods with adjustable height greatly facilitates their storage, distribution and use in work. If you remove the tripods and remove the reclining shelf, then this table is transformed into the student's traditional individual desk, which is moFig. 2 can be used as a student for teaching any school subject.

In one of the rear side racks of the countertop frame, hidden technological holes are provided for the electrical wiring necessary to power all used devices and installations. The movable shelf can act as a lifting table, necessary not only to increase the working surface of the table, but also to use it more efficiently: an additional shelf appears to accommodate the devices used, the problem of the visibility of the equipment is resolved, and the opportunity is created to divide the working space (unnecessary at the moment) learning subjects can be placed on the top shelf), in addition, this shelf can serve as a stand for the monitor.

a device block containing power supplies, measuring instruments, a timer, a device for interfacing with a computer. F

FIG. 5

On the assembly drawing (Fig.6) presents a table containing the tabletop 1 and shelf 2, two metal frames 3 and 4, on one of which 3 the tabletop 1 is fixedly mounted, and on the other 4 - shelf 2, vertically

moving relative to the countertop 1 until it comes into contact with the formation of a single working horizontal surface.

The solid rear panel of the shelf not only protects the devices placed there, but also obscures the niche. Providing the shelf with a specially made metal bar bent along its half-perimeter allows it to be used in one position for attaching dimming shutters when conducting experiments on optics that do not require dimming of the entire class (Fig. 4). This niche has a folding metal plate, adapted to accommodate devices with magnetic holders. Figure 5 is a photograph showing the use of this table in conjunction with a computer in the physics office. Figures 6-8 show an assembly drawing of a table with specifications.
