Description

The proposed technical solution relates to mechanics, assemblies and rotating parts, in particular, hinges, and above all, to their locking devices used in furniture production, for example, in adjusting and fixing the desktop in a certain position for the convenience of the user.

The known solution RU 132692 U1 “Chair with a lifting table”, IPC A47B 39/02, containing a table lifting mechanism with the ability to move the table from a position above the seat to a position above the back of the chair. The mechanism for moving the table contains a swivel, a gas spring to compensate for the weight of the table, the ability to install an electric drive.

The disadvantage of this solution is that this mechanism has only two positions of the table above the seat and above the back of the chair. It is not possible to adjust the countertops relative to the user along the horizontal axis. (RU 132692 U1, www1.fins.ru).

The known solution RU 184874 U1 “Computer workstation”, IPC A47B 21/00, containing a mechanism for moving the chair elements, as well as a support with a platform for mounting the monitor and with rods for changing the position of the platform depending on the position of the chair. A ratchet mechanism is used to adjust the position of the table.

The disadvantage of this solution is that the proposed mechanism for adjusting the position of the table allows tuning only along the vertical axis. (RU 184874 U1, www1.fips.ru)

Of the known technical solutions, the closest in purpose and technical nature to the claimed object is the solution US 3604734 "Adjusting and locking mechanism for adjustable and folding tables" containing the adjustment mechanism in which the outer tubular element is attached to the base of the table, and the inner tubular element is a support countertop. The adjusting mechanism is designed to vertically adjust the tabletop in height. It contains a locking element attached to the outer tubular element, while the locking element contains an elastic arm integrally formed with the outer tubular part and is provided with a cup-shaped part moved inward and outward from the mesh with the outer surface of the sleeve to press it against the inner tubular element for blocking action and release it from the inner tubular element to unlock. There is also a manual drive in the form of a screw, which, when tightened, presses on the cup-shaped part of the elastic lever, thereby pressing the sleeve against the inner tubular element, fixing it, and when unscrewing, releases the sleeve from engagement, which allows the inner tubular element to move freely.

The disadvantage of this solution is that when using this mechanism to adjust and fix the height of the countertop, slipping of the tabletop support is possible due to the weak clamping force of the sleeve to the inner tubular element. Also, this mechanism does not allow you to adjust the angle of rotation of the tabletop support around a vertical axis. (US 3604734, www.uspto.gov).

SUMMARY OF THE INVENTION

The problem the claimed solution is aimed at is the development of an adjusting and fixing device with a simple design, small dimensions, and a minimum number of structural elements, which makes it possible to more flexibly adjust the position of the bracket relative to the user, allowing him to move both along the horizontal and vertical axes, and around them.

The claimed adjusting and fixing device includes a frame (1), a pivot-swivel joint (2), a support (3), a plate (4), an adjusting screw (5), an axis (6), a guide (7), inserts (8), a fixing screw (9), a beam (10), a fixing screw (11) for fixing the bracket (13) for the laptop, a screw (12) for fixing the bracket for the ipad of FIG. 1.

At the end of the frame (1), a support-swivel joint (2) is mounted coaxially, which is interfaced with the support (3) of the guide (7). The support (3) is connected to the plate (4), which has a through threaded hole and serves to move the adjusting screw (5). The support (3) is also connected through the axis (6) with the eye of the guide (7). The guide (7) contains a fixing screw (9) and provides a linear movement of the beam (10). At the ends of the guide (7), inserts (8) are installed. On the end side of the beam (10) of FIG. 1, 2 there is a screw (12) for fastening the bracket for the ipad. At the end of the beam (10), a fixing screw (11) is placed on the upper surface for mounting the laptop bracket (13) of FIG. 12.

The frame (1) of FIG. 1 - serves as the supporting basis of the adjusting and fixing device.

Swivel joint (2) of FIG. 1 - allows you to change the position of the device by rotational motion around its vertical axis, thereby pushing or pulling the bracket away from the user.

The support (3) of the guide (7) of FIG. 1 - the element is designed to install the guide (7) on the pivot joint (2).

The plate (4) of FIG. 1 - a part with a through threaded hole, which allows the adjusting screw (5) by twisting and unscrewing to change the angle of inclination of the guide (7).

The adjusting screw (5) of FIG. 1 - a rod with an external thread that allows you to adjust the angle of inclination of the guide (7) by raising or lowering the guide (7) with the beam (10) along the vertical axis, which allows you to adjust the optimal position of the bracket along the vertical axis.

The axis (6) of FIG. 1 - connects the support (3) with the guide (7) and allows you to change the position of the guide (7) of the beam (10) along the vertical axis.

The guide (7) of FIG. 1 - detail, providing a linear movement of the beam (10). It is made of a rolling profile. In the profile section, it repeats the sectional shape of the beam (10), which moves in the structural space of the guide profile (7). On the upper plane, the guide (7) has a threaded hole for tightening the fixing screw (9).

The insert (8) of FIG. 1 - detail designed to reduce the friction of the movement of the beam (10) in the structural space of the guide (7).

The fixing screw (9) of FIG. 1 - rod with external thread, which allows to fix the beam (10) in a certain position, thereby adjusting the extension length. The location of the fixing screw (9) on top allows you to fix the beam more reliably, in contrast to the known analogue.

The beam (10) of FIG. 1, 2 - a part consisting of a rolling profile, performing linear - translational motion, allows you to adjust the degree of extension of the bracket. In the particular case of execution, the beam (10) in the profile section has a square, rectangular, round, oval, polyhedral shape.

The fixing screw (11) of FIG. 1 - a part intended for connecting the beam (10) with the bracket 13 is located at the end of the beam (10) on the upper plane.

The screw (12) of FIG. 1, 2 - a part designed to connect the beam (10) with the bracket for the ipad.

The adjusting and fixing device can be used alternately with a laptop and with an iPad.

As a result, the claimed design allows the user to configure the workplace in the optimal position for convenient operation, by adjusting the extension of the bracket, which allows you to set the horizontal position relative to the user, namely in the center or from the edge of it, the rotation of the pivot joint, thereby adjusting the distance between the bracket and the user, the angle of the guide, which changes the height of the bracket along the vertical axis, changing the position of the bracket due to its rotation That allows you to make an adjustment bracket relative to eye level.

The technical result that can be obtained by carrying out the invention is to achieve optimal workplace settings for long-term, convenient user work.
