Mr. J-, LABORATORY TABLE

The utility model relates to laboratory tables used in chemical and physical laboratories of any profile.

For chemical and physical laboratories of various profiles (industrial, research organizations, clinics, pharmacies, centers for sanitary and epidemiological surveillance), specialized laboratory tables must be used, which must meet the following conditions: increased reliability and ease of use, enhanced functionality, and resistance to impacts aggressive environments and high temperatures, compactness, ergonomics and aesthetics.

The well-known "Laboratory stand A 47 B 81/00, described in the USSR Copyright Certificate No. 1662486 with priority dated March 29, 89, published in Bulletin No. 26 of July 15, 91.

The specified stand relates to educational and laboratory equipment and is designed to perform physical and chemical work.

The laboratory bench contains a rectangular frame with side walls, a panel and a shelf for installing devices, and the panel is equipped with a movement mechanism to expand the operational capabilities of the bench and increase ease of use.

This stand does not contain some sanitary-engineering elements (sinks, titration units) necessary for conducting physical and chemical tests.

Separate washing tables for laboratory work are widely used.

So, for example, there is a washing table provided in the magazine-prospectus "Ecros, ed. St. Petersburg, 1999, on page 11.

The design of this sink is a quadrangular cabinet with a door, has a stainless steel sink with drain in the upper part, a water tap, and a dryer located vertically behind the tap. The dryer is made in the form of a panel with a series of inclined pins located on it. Dimensions of the washing table 500 x 850 x 1300 (mm).

Separate titration units for laboratory work are also widely used. So, for example, the title unit is given in the magazine-prospectus "Ecros, ed. St. Petersburg, 1999, on page 15.

The design of this installation is a rectangular table with a titration stand located on it. In this case, the table consists of a metal frame, countertops with a working surface of laminate and two drawers located under it. Titration

IPC in 01 L 9/02

the rack is mounted vertically, has tripods with tabs for attaching burettes, as well as upper and lower illumination of the rack.

Dimensions of the titration unit 1200 x 600 x 1830 (mm).

Also known and is the closest in technical essence to the claimed device as a utility model is the design of the Chemical Island Table, an image of which is presented in the journal “Ecros, ed. St. Petersburg, 1999, on page 6 (prototype).

The specified design includes a base and a centrally located superstructure. The base is made in the form of a metal frame with legs, a rectangular countertop with laminate flooring and several drawers under the tabletop. In the center of the base is a narrow rectangular sink with a water tap and appropriate fixtures. The stand is made in the form of a U-shaped metal rack and is located above the sink. The table is equipped with a backlight, the lamps of which are located in the upper part of the table, as well as switches and sockets for electrical appliances.

The overall dimensions of this table are 1200 x 1450 x 1270 (mm).

A drawback of the design of this chemical island table is that for practical work at such a table, additional laboratory furniture with a different functional purpose is required. This significantly increases the total area occupied by a full set of laboratory furniture, necessary for multifunctional work.

The objective of the claimed utility model is to create a multifunctional laboratory bench, the design of which, on the one hand, combines in a compact form the most necessary laboratory devices and provides two workstations, and on the other hand, meets the requirements of ergonomics.

The problem is solved by the following.

The laboratory table includes a base, consisting of a metal frame with legs and a rectangular countertop, which has a chemically resistant coating, with a sink built into it with appropriate plumbing fixtures, as well as a center table in the form of a U-shaped rack located in the center of the base.

The distance between the opposite sides of the countertop is 140 - 160 cm, and the superstructure has a height of 50-80 cm from the base and is made with two side walls and at least one horizontal shelf between them. The table also includes a drying rack, made in the form of a panel with pins, and a titration unit having a horizontal working platform, lined with ceramic tiles and a vertical rack with tripods for attaching burettes, a screen and backlight.

In this case, the sink and the working surface of the titration unit are located at opposite ends of the countertop in front of the side walls of the table, and the drying rack is mounted on one of the side walls of the table (at the sink of the sink) at an angle of 0-90 ° to this wall, and on the other side wall of the table a vertical stand is fixed with tripods, a screen and a backlight for the title unit (for a horizontal working ploshch, adki made of ceramic tiles).

At two other opposite ends of the table, general-purpose workplaces are formed with the possibility of access from both sides to the open shelves of the table. Thus, the claimed laboratory bench is an island.

Typically, the table is equipped with switches and sockets for connecting electrical appliances.

The execution of the rectangular top with the distances between the opposite sides within 140-160 cm allows you to compactly fit the sink and the title unit into the dimensions of the table and at the same time provide two general-purpose workstations located on opposite sides of the table symmetrically relative to the table. An increase in the size of the countertops reduces the compactness of the laboratory island table.

The table has one or more shelves open on both sides, and its height is within 50-80 cm from the countertop. This, with a standard table base height of 85-90 cm, allows even a short person to work behind it; with an increase in the height of the cradle, the ergonomic indicators of reach sharply worsen.

For the practical work of two laboratory assistants, the dimensions of the superstructure of 20 x 40 cm are minimally acceptable.

Practically convenient and ergonomically justified for working at the table is a general-purpose workplace with a width of 70-90 cm and a depth of 40-60 cm.

At the same time, the indicated tabletop dimensions, taking into account the minimum allowable dimensions of the table top, provide the necessary depth for general-purpose workplaces, as well as the possibility of placing a standard sink 40 X 40 cm and a typical titration unit with a horizontal working platform of ceramic tiles 40 x 40 cm.

Thus, the indicated dimensions of the countertop provide ergonomic performance of the claimed table, and the integrated presence of a sink and a titration unit together with two general-purpose workstations in a single design of the island laboratory table makes it possible to use it multifunctionally.

In the particular case of a laboratory bench, the corners of a rectangular tabletop are cut so that the length of each of its two opposite edges from the side of general workplaces is within 70-90 cm, and the other two opposite edges from the sink and titration side are within 45 -55 cm

This shape of the tabletop in the form of an octahedron makes the table more compact and requires a smaller area for its installation.

In the particular case of the laboratory bench, all the corners of a rectangular worktop are rounded.

The specified execution of the countertops makes the table safer for laboratory assistants during work than in the case of a table with sharp corners.

In the particular case of the execution of the laboratory bench, the chemically resistant coating of the base countertop is made in the form of a laminate, stainless steel or ceramic.

These types of coatings provide the necessary chemical resistance and mechanical strength of the surface of the countertop during a wide range of chemical and physical laboratory tests, and are also common and available materials for the manufacture of the inventive laboratory table.

In the particular case of the execution of the laboratory table, the countertop has at least one of the sides a sliding horizontal working panel on the guide bar.

This design of the table allows, if necessary, to use the additional surface of the sliding panel for conducting laboratory records without reducing the initial compactness of the table as a whole.

In the particular case of the execution of the laboratory bench, the base under the sink has a stand firmly attached to the frame and having at least one door.

This design of the table allows you to place in this cabinet a container for collecting used water, access to which is provided through at least one door in the cabinet, which allows you to use the sink without stationary sewage.

In the particular case of the execution of the laboratory bench, the base, at least under one of the workstations for general purposes or under the titration system, has a stand firmly attached to the frame, and the stand is made either with drawers or at least one door.

in the particular case of the execution of the laboratory table, it is equipped with at least one rolling cabinet, with the possibility of its location by the base countertop, and the cabinet is made either with drawers or at least one door.

This design of the table allows you to place, if necessary, the same rolling cabinet in different places of the table, as well as around it, which extends the invariance of the use of the table. In the case of a rolling cabinet near the table, next to the laboratory assistant, its top is used as an additional work surface, which increases the usability of the laboratory table.

Thus, the use of the inventive laboratory bench with the features mentioned above allows you to compactly combine in a single design the most necessary laboratory devices and two general-purpose workstations, taking into account ergonomic requirements, which extends the functionality of the table.
