RU187438U1 - Weight stool in his seat - Google Patents

Abstract

A stool with a weight gauge on its seat includes a seat, a stool base, legs, a false bottom, ties, tensile weights, including strain gauges, an electronic unit and an electrical connection between the load cells and the electronic unit. When the load on the seat changes, telemetry signals are activated from the electronic unit to an external computing device due to the fact that there is a change in the impact on the load cells, which are installed on the basis of the stool and are in contact with the seat connected to yazhkami with false-dnom.Konstruktsiya stool constructed in such a way that on the basis tenzovesy attached stool, which is disposed between the seat and the false-bottom and is connected to the legs. Cutouts are made at the base of the stool through which the seat ties with a false bottom pass, while the false bottom has holes through which the legs of the stool pass.

Description

The claimed technical solution of the stool relates to pieces of furniture, in particular furniture for medical rooms and can be used to determine the weight of a person sitting on it, or any item on its surface, and can also be included in a weight change monitoring system.

To determine the weight, strain gauge (strain gauge) scales are used.

A stool is known as a seat device and it always includes a seat and legs that are connected to the seat.

The prior art designs of devices for seating, which, in the presence of a certain weight on the seat, make it possible to measure its value (see patent (19) RU (11) 2 421 133 (13) C2 (51) IPC A61B 5/103 (2006.01) , A61B 5/107 (2006.01), G01G 9/00 (2006.01), G01G 19/40 (2006.01), G01G 19/64 (2006.01), (54) GLOBAL SYSTEM FOR PREVENTION OF OBESITY AND TRACKING FOR OVERWEIGHT AND OBESITY), where The basic structure of the weighing apparatus (WAPP) of the SVOPM module is described, which can use two weighing devices to weigh a person in a car.

The weighing platform of the first weighing device is located in the person’s car seat and can measure the weight of the part of the person’s body located in the chair. The weighing platform of the second weighing device of the WAPP apparatus measures the weight of a person’s legs and can be fixed or extendable from a suitable part of the car or be in the car mat under the person’s legs. To weigh the driver, the WAPP checks for the presence of the driver in the driver’s seat by processing the data received from the weighing device in the driver’s seat and will continue to scan the weight in the driver’s seat until the driver sits in the driver’s seat. The disadvantage of this system is its complexity in the presence of redundant functions.

A known design of a device for measuring the weight of a passenger car (see application US2012318072 (A1) - DEVICE FOR MEASURING THE WEIGHT OF A PASSENGER OF A CAR), where the design of the vehicle seat is equipped with a load cell.

at least one of the second part of the wall and the third part of the wall and at least one of the fifth part of the wall and the sixth part of the wall are integral, integrally connected by a second extension wall extending in the opposite direction.

A known seat structure of a vehicle equipped with a load cell (see patent (19) RU (11) 2 593 653 (13) C1 (51) IPC G01G 9/00 (2006.01) G01G 19/44 (2006.01) (54) METHOD OF WEIGHING A HUMAN IN THE CAR SEAT, ON-BOARD WEIGHING SYSTEM AND WEIGHT MODERATOR), where the on-board person weighing system in the car includes a weighing device, a weight moderator mounted on a vertical platform, a push switch and a computing and control device connected to the weighing device. The weighing device is integrated in the vehicle seat and is equipped with an output signal proportional to the weight of the person sitting on the seat. The push switch is connected to the computing and control device and is equipped with an output signal source.

The disadvantage of this device is its complexity.

A known design of electronic telescopes (see the description of the patent for the invention (19) RU (11) 2044283 (13) C1 (51) IPC G01G 3/14 (1995.01), G01G 3/10 (1995.01) (54) ELECTRONIC TENZES). The invention relates to two-support tensometric scales and can improve the accuracy of weighing. The weighing module consists of a housing with a cover, inside of which a weighing device is installed, containing a weighing platform with attachment points, a base and a rigid load-measuring frame, consisting of two parallel power beams and two weight supports, each of which has upper and lower power shoulders and a force sensor between them in the form of a parallelogram elastic element with strain gages. The longitudinal axis of the power beams are placed in the vertical plane of symmetry of the parallelogram elastic elements. The lower longitudinal power beam is connected to the base by means of two mutually perpendicular support elements located at its opposite ends. The attachment points of the weighing platform are located at the end sections of the upper longitudinal power beam adjacent to the weight supports.

The design of the inventive stool with a determinant of weight on its seat hereinafter - "stool" is presented in the Figure - view - versions of the stool.

The stool has in its composition:

1 seat

2 base

3 cut-outs on the basis (for couplers),

4 legs

5 false bottom

6 screeds,

7 holes on the false bottom through which the legs of the stool pass,

8 supports under load cells,

9 load cells

10 electronic unit,

11 electrical connection between the load cells and the electronic unit.

The technical result of the claimed technical solution for the stool is the creation of a convenient household furniture product with an additional weighing function, where when a load appears on the seat 1, which, acting on the load cells 9, programmatically activates the tensile weights, including several load sensors 9 and an electronic unit 10, as well as electrical connection 11 between the load cells 9 and the electronic unit 10, the signal with the result of weighing from which is fed to an external information processing device (in the drawing shown). The seat 1 and the false bottom 5, connected by screeds 6, are lowered down, distributing the load on all load cells 9. The false bottom 5 additionally performs the function of a clamp for legs and increases the strength of the stool.

Description of the claimed technical solution

The stool has in its composition:

seat1, base of stool 2, legs 4, false bottom 5, couplers 6, supports for load cells 8, tensile weights including load cells 9, electronic unit 10, electrical connection between the load cells and electronic unit 11. (The applicant considers that the power supply may be implemented in the form is an integral part of the electronic unit and does not consider it as a separate element).

The shape of the stool is mostly round, but can be square, oval or any other arbitrary shape. Seat 1 is in contact with load cells 12.

The base of the stool 2 is made with cutouts 3 through which the ties 6 pass between the lower surface of the seat 1 and the upper surface of the base of the stool 2.

For the connection between the legs 4 and the base of the stool 2, a metal frame can preferably be used, in which there are nests with thread for the mating thread on the legs 4, or this connection is made using other known structures: a wooden frame with legs attached to it; either formed by directly connecting the legs to the base of the stool.

The false bottom 5 has openings 7 through which the legs of the stool 4 pass, arranged uniformly on it (the number of holes coincides with the number of legs).

Ties 6 are made in the form of rectangular parallelepipeds and are connected to the seat 1 and the false bottom 5 by means of screws, nails, staples, hairpins, screws, glue.

The load cells 9 are evenly fixed on the base of the stool 2, and under them on the false bottom 5 with a gap of 2 ÷ 8 mm are mounted supports 8.

The electrical connection between the load cells 9 and the electronic unit 10 is made by means of wires 11.

With an external computing device (not shown in the drawings), the electronic unit 10 contactlessly exchanges telemetric signals.

To create mechanical reliability of the structure under the load cells on the false bottom 5 at a distance of 2 ÷ 8 mm, supports 8 are attached.

The device operates as follows.

The seat presses on the load cells mounted on the base of the stool. When the weight on the surface of the seat changes, the resistance of the load cells changes, which activates the electronic unit for the duration of the measurements. Information regarding the measured weight is transmitted from the load cells to the electronic unit. Then, signals transmitted to an external information processing device are generated on the electronic unit.
