Description

The utility model relates to furniture, in particular to computer workstations.

The prior art known, see, for example, the description of patent RU 2264772C1, IPC A47B 39/02, 83/00, publ. November 27, 2005, computer workstations, including a base, a platform for a monitor, a seat with a backrest, head restraint and armrests, an electric drive and means for interdependent change of position of these elements relative to the base.

With the development of computer technology, heavy and dimensional monitors with cathode ray tubes have replaced lightweight flat monitors with liquid crystal displays. Accordingly, the design of computer workstations has changed.

From the description of the patent US 8087724 B2, IPC A47C 7/62, publ. 01/03/2012, the design of a computer workstation is known, including a base, an electric drive, a support ring frame that is rotatable, and a chair and a flat monitor mounting bracket mounted on a support ring frame.

The disadvantages of the design of this station are increased dimensions and restrictions on the possibility of changing the spatial position of the elements of the chair.

For the closest analogue of the utility model, the design of a computer workstation, known from US9955785 B2, IPC A47B 83/02, A47C 1/00, A47C 1/024, publ. 05/01/2018, which includes a base, an electric drive, a chair with adjustable elements (bottom, back, head restraint, leg support and armrests) and a mechanism for moving chair elements, as well as a table for the keyboard and monitor support made by L-shaped in terms of shape and consisting of pipes connected by a hinge, and inside these pipes traction is laid. The rods are connected to the support sections and to each other by parallelogram communication elements.

The disadvantage of the closest analogue is the high complexity of the support assembly, due to the limited access for mounting rods installed inside the pipes that make up the support.

Another disadvantage of the analogue is the design complexity due to the movable connection of the pipes that make up the support.

A disadvantage of the analogue is also the attachment of the support to the chair in the place where the user's hip joint should be located, because of which, when the chair back is folded back, the support synchronously raises the monitor and the user looks at the monitor with his head thrown back. In this position, working on a computer is significantly difficult.

Finally, the analogue is a device for fixing the table for the keyboard, because of which, when the chair back is tilted, the table rises, which leads to numbness and numbness of the user's hands. Due to the possible vertical deviation of the table in the analogue, it was necessary to magnetically fasten the computer mouse and keyboard to the surface of the table.

The technical results that the utility model aims to achieve are to reduce the complexity of assembling a computer workstation and simplify its design while maintaining the ergonomic characteristics of a computer workstation.

The above technical results are achieved in a computer workstation, which includes a base, a chair with adjustable elements, a mechanism for moving the chair elements, as well as a support for the monitor with rods for changing the position of the monitor depending on the position of the chair.

Technical results are achieved in that the support is made L-shaped in terms of shape by welding from metal profiles of a U-shaped cross section connected by metal bars and attached to the bottom of the chair in the area of the user's knees, and the rods are located outside the support of the computer workstation.

Reducing the complexity of the assembly of a computer workstation is ensured by the rejection of the use of pipes in the structure of the support, with the exception of the movable connection of the pipes to each other and the refusal to place rods with parallelogram elements for connecting rods to the sections of the support and between themselves inside these pipes. In the proposed design, rods and parallelogram coupling elements are located on the outside of the support.

Simplification of the design of the computer workstation while maintaining its high ergonomic characteristics is due to the rejection of the movable connection of the support parts and a significant shortening of the support length due to the attachment of the support to the bottom of the chair in the area of the user's knees.

The utility model is illustrated by the following images. In FIG. 1 shows an assembled computer workstation; In FIG. 2 shows various positions of a computer workstation;

In FIG. 3 shows a monitor support, side view;

In FIG. 4 shows a support for a monitor in isometry. The positions in the image are:

1 - computer workstation; 2 - base; 3 - the bottom of the chair;

4 - back of a chair; 5 - support for the legs of the chair; 6 - headrest;

7 - armrest of a chair; 8 - support for the monitor; 9 - thrust;

10 - platform for mounting the monitor; 11 - center of rotation of the support;

12 - the center of rotation of the site; 13 - part of the ratchet mechanism;

14 - lever; 15 - crossbar; 16 - monitor; 17- a table for the keyboard.

The utility model can be implemented in the design of computer workstation 1, see FIG. 1, which includes an electric drive (not shown in Fig.), A base 2, a chair with a bottom 3, a back 4, a foot support 5, a head restraint 6 and armrests 7, as well as a support 8 for a monitor, traction 9, a table 17 for a keyboard and a pad 10 for mounting the monitor 15.

To implement the utility model perform the following changes in the design of the support 8.

The support 8 is made L-shaped in terms of shape (see Fig. 3.4) by welding from metal profiles of a U-shaped cross section connected by metal bars 15.

This design provides the required rigidity of the support and facilitates the assembly process of the computer workstation 1, since the installation of rods and the wiring of the electrical wiring to the monitor (wiring is not shown in the figure) are performed with full access to the support.

Since the support is attached to the bottom 3 of the chair in the area of placement of the knees of the user, significantly reduced the length of the support 8 and improved ergonomics of movement of the monitor 16.

To adjust the position of the table 17 for the keyboard, a ratchet mechanism is used, part 13 of which is attached to the support 8.

A computer workstation is used in a traditional way.

If it is necessary to change the position of the chair, the user gives a command to the electric drive, which, using the movement mechanism, sets the adjustable elements of the chair to the desired position.

When changing the position of the adjustable elements of the chair under the influence of the electric drive, the lever of one of the armrests 7 (the armrest lever in Fig. Is not indicated) acts on the lever 14 of the support 8, as a result of which the support 8 rotates relative to the center of rotation 11.

Simultaneously with the rotation of the support 8, the rods 9 move, while the platform 10 for mounting the monitor rotates around the center of rotation 12.

The rotation of the platform 10 occurs in such a way that the monitor installed on this site is always directed towards the operator at the same angle.

In the closest analogue, the transformation of the station when folding the chair back occurs in 2 stages:

- the back is tilted back, the horizontal part of the support remains stationary, and the vertical part of the support at the bend is tilted to the back;

- at a certain moment of back deflection, the hinge in the place of bending of the support parts is blocked and then the horizontal part of the support rotates.

In the claimed computer workstation, two stages of transformation are replaced by one stage, thereby improving the ergonomics of moving the monitor.

Conducted patent research confirmed the world novelty of the claimed utility model.

The manufacture and operation of the prototype confirmed the industrial applicability of the utility model and its compliance with the stated technical results.
