Description

The technical field to which the utility model relates.

The utility model relates to furniture intended for the organization of the workplace, both in production and in domestic conditions. The table provides the ability to adjust the height of the countertops, including for alternating between sitting and standing positions and can be used, for example, for working on a computer, training, writing, etc.

State of the art

Known table (RF patent for the invention No. 1812959, publ. 04/30/1993), containing two work surfaces mounted on a horizontal frame using brackets. The frame is rigidly connected to the spindle, which is threaded part mates with the threaded part of the handwheel. Regulation of the position of the surfaces in height is carried out by rotating the handwheel.

The disadvantage of the above table is the manual drive, which is complicated and inconvenient in operation due to the complexity of the height adjustment mechanism. In addition, the presence of one support limits the scope of the table, since it is not always possible to put a table with a massive base in the form of a plate.

Known adjustable table (RF patent for the invention No. 2090128, publ. 09/20/1997). The table contains a housing, a tabletop mounted in a housing with the ability to move in a vertical plane, a mechanism for moving and fixing the tabletop connected with its end faces, including two drums connected by a common shaft, through each of which a cable is thrown, and a control lever, a friction clutch, this control lever is made foot.

However, this table also has a limited scope, as it cannot be used in office and living conditions. In addition, it has a complex mechanism for moving and fixing the countertops, which reduces the manufacturability of its manufacture and ease of use.

Known adjustable table (US application for invention US 4604955, publ. 08/12/1986) containing a base with at least one first support column, a tabletop mounted to move relative to the base, and a mechanism for moving the tabletop with a drive, while the tabletop is rigidly connected to at least one second support column provided with guides cooperating with mating surfaces on the first support column, and the table top movement mechanism fixed to the base includes at least at least one screw with at least one nut and at least one support platform for moving the countertops.

However, this table also has low manufacturability, is not convenient to use and has a limited scope due to the implementation of the worktop from two halves.

Known height-adjustable table with one support in the center of mass, capable of rotating around a vertical axis (European patent No. 85303990.7, publ. 05.06.1985). Although this table does not have the drawbacks of most of the currently manufactured desktops: the absence of any adjustments and in shape resembling bulky cabinets, but the design of this table still does not meet all modern requirements. A large spread of anthropometric parameters between adults and children, neglect of body position when working at the table leads to early curvature of the spine in children and aggravate this in adolescence and youth.

Considered as an analogue, the table cannot provide a person in a standing position, and cantilever fixing of the countertop complicates the manual adjustment of its height. The lower support, made in the form of a three-beam star, does not provide the same stability of the table in all directions, and can also interfere with a comfortable fit of a person. By reducing the length of the rays of the lower support, the structural stability decreases (the likelihood of tipping over increases).

The closest in technical essence and the achieved positive effect to the claimed table - the prototype - is an adjustable table (RF patent for the invention No. 2354274, publ. 05/10/2009) containing a tabletop mounted on a vertical support and equipped with a mechanism for changing its height and vertical locking means support from rotation. The vertical support is made in the form of a rod equipped with units for installing it in a spacer between the upper and lower surfaces. The mechanism for changing the height is made in the form of a screw pair connected to the drive, the lead screw of which is mounted by means of an arm on the rod, and the nut is mounted on a slider mounted to move along the rod with a rigidly fixed tabletop. The nodes of the installation of the rod are equipped with fixing elements on the surfaces.

A disadvantage of the known device is the bulkiness of its design, as well as the complexity of the mechanism for adjusting the height of the table.

Utility Model Implementation

The table with adjustable height contains: countertop 1, legs 2 connected by a crossbar 3, gas cartridge 4, vacuum suction cups 5 on the base of the table legs.

Each leg 2 of the table is made of three hollow metal telescopic tubes 2a, 2b and 2c. The widest part 2c is located at the base, the middle 2b is inserted into it. The pipes have different diameters, and the diameter of the pipe 2c is larger than the diameter of the pipe 2b, and the diameter of the pipe 2b is larger than the diameter of the pipe 2a by an amount sufficient to slide one pipe into another. On the lower part of the pipes 2b and 2c, several threaded holes 6 can be made into which the locking screw 7 is screwed, thereby providing additional height adjustment of the table (see Fig. 2). In the middle part 2b, the upper part 2a is inserted, which glides during the operation of the gas cartridge. Thus, the lower 2c and middle 2b parts are the static height adjustment (set one-time when assembling the table according to the user's height), the middle 2b and upper 2a are switching between sitting-standing positions. In addition, even for the sitting position, using height adjustment, you can always individually select the required level of the countertop 1 by adjusting the static height of the table between the parts of the legs 2B and 2B.

To increase the rigidity of the table structure, it is possible to use an additional crossbar (shown in dashed lines in Fig. 1) connecting the lower parts of the legs 2.

The gas cartridge 4 is located perpendicular between the countertop 1 and the crossbar 3 and is a pneumatic piston in the form of a steel cylinder filled with an inert gas. It allows you to smoothly adjust the table in height and acts as a shock absorber. For ease of use of the lifting mechanism, the gas cartridge 4 can be equipped with a lever. Standard gas cartridges, as a rule, can withstand up to 100 thousand cycles of dynamic load of 120 kg. Due to equipping the table with a pneumatic height adjustment mechanism, it is possible to quickly transform the table from the position for working “sitting” to the position for working “standing”, and vice versa.

Vacuum suction cups 5 are designed to prevent the displacement of the table when lifting the countertop 1 to the required height. Vacuum suction cups 5 fully perform their function only when installing the table on a smooth floor without carpet. Between the vacuum suction cup 5 and the surface of such a floor, a negative pressure (or vacuum) is formed, due to which the table is held. It has been experimentally established that, in order to provide the necessary holding power, the diameter of the suction cup should be more than 120 mm.

A possible installation of several gas cartridges 4, for example two, moreover, they can be installed at an angle (see figure 3 and 4).

Under the tabletop, brackets 8 can be installed (see Fig. 4), and the gas cartridges 4 are fixed movably (can rotate around the fasteners 9) with the lower ends on the lower crossbar, and the upper ones on the brackets 8. The brackets 8 make the gas cartridges 4 accept the position of the "negative angle" when the countertop 1 is lowered.

If a height-adjustable table is used as a computer table, it is possible to use a swivel bracket for fixing the LCD monitor in the table design.

In the design of the table, a cable channel can also be used, which is attached on the underside of the countertop 1, using this additional device, you can collect all the wires in one place, thereby ensuring order on the desktop.

The gas cartridge 4 serves as the lifting mechanism. The height-adjustable table works according to the “car trunk” principle (see FIG. 4), when in the closed position of the table the gas cartridge 4 is in a negative angle with respect to the countertop 1 and thus “presses ”It down, and to open the countertop you need to make an effort that will“ squeeze ”the gas cartridges 4 and again allow them to open, this time to the end, bringing the countertop 1 to its maximum height.

Figure 4 shows what happens to the gas cartridges 4 without a lever when the tabletop 1 is lowered. The brackets 8 force the gas cartridges to take a “negative angle” position when the tabletop 1 is lowered. Since the gas cartridge 4 without a lever always tends to open, then in this position both gas cartridge 4 tend to squeeze out their piston, which together with their "negative angle" forces them to "press" tabletop 1 to the table.

When using a gas cartridge 4 with a lever - when the lever is pressed, it presses the “set” force from below on the tabletop 1, lifting it with the contents. To lower the countertop 1, you must first press the lever of the gas cartridge 4, it is unlocked to move up or down, then, without releasing the lever, with a light movement of the hand, press on the countertop from above. Depending on how the weight of the contents of the countertop 1 and the lifting force of the gas cartridge 4 are balanced, it will be necessary to apply more or less force by hand.

Such a height adjustment mechanism provides a quick transformation from a sitting position to a standing position, and vice versa. The process of changing position takes literally a few seconds.

Given the simplicity and speed of transformation, any user can independently, without much effort and time, change the sitting-standing position as many times as necessary during operation.

This table is convenient for long sitting work: for programmers, designers, designers, system administrators and other users who have to work at a computer for a long time.

Since sedentary sedentary work for hours on end has a lot of negative consequences, a change of position is a natural and effective way to redistribute loads on different parts of the body. In addition, even for the “sitting” position by adjusting the height, you can always individually select the required level of the countertop 1.

Thus, as a result of the implementation of the claimed utility model, simplification of movement and fixation of the countertop, expansion of the control range, improved ergonomics, as well as the adaptability of the assembly table with adjustable height are provided.

A comparative analysis of the claimed utility model showed that the set of essential features of the claimed device is not known from the prior art and therefore corresponds to the patentability condition “Novelty”.

The above information confirms the possibility of using the claimed table for organizing an ergonomic workplace, both in production and in domestic conditions, and therefore meets the patentability condition “Industrial Applicability”.
