Description

FIXED SEAT (OPTIONS).

The invention relates to furniture, namely to removable seats used to prevent spinal curvature during sitting, as training devices for the development of coordination, balance and various groups of the spinal muscles and abdominal press, rehabilitation treatment, in particular the spinal column. It can be used as a seat in everyday life, school, at work and leisure, in rehabilitation treatment departments of hospitals, sanatoriums, hospitals, as well as in sports halls.

State of the art

A device is known for restorative treatment of back muscles, including support with a swivel seat (see, US patent, JVB3824991, class A 61 H 1/00, 07/23/1974).

The known device does not provide swinging movements of the seat in all planes with a variable load, i.e. full training and comprehensive rehabilitation treatment of the vertebral joints of the back muscles and abdominal muscles.

The closest to the invention in technical essence and the achieved result is a seat containing a balancing element and a support, and on the latter there is a rack with a hinge through which the support is connected to balancing element, (see copyright certificate SU

M> 946565, CL. A 63 B 23/02, 07/30/1982).

This device is a comprehensive device for conducting rehabilitation treatment in health care facilities, which narrows the scope of its application and does not make it possible to use it in the workplace while seated, in schools or at home as a preventive measure. In addition, this device lacks tools that would allow it to be used to collect statistical information, for example, on the number of swinging movements of a certain orientation and the possibility of transmitting other information for people with certain physical limitations.

Disclosure of invention

The problem to which the present invention is directed, is to simplify the design of the seat while expanding its functionality.

The technical result achieved by the implementation of the invention is to expand the field of use of the seat in everyday life, in educational institutions and in production as a preventive and health-improving means for training certain muscle groups of the back and abdominal press.

This problem is solved, and the technical result is achieved due to the fact that the overhead seat contains a balancing element and a support, and on the latter there is a rack with a hinge through which the support is connected to the balancing element, while the contour of the platform of the balancing element is formed in plan by pairing 3 arc circles and 3 straight lines tangent to arcs, and two straight lines form the lateral edges, and the third straight line forms the leading edge, while the depth of the balancing element is 1-0.75 of its width, the point of support of the balancing element on the hinge is located on its axis of symmetry at a distance from its leading edge of 0.35 to 0.45 of its width, the distance from the support to the balancing element at the location of the hinge is from 0.07 to 0, 125 the width of the balancing element, the ratio of sizes in terms of support with the balancing element is 0.8-0.9, the hinge with the stand is located on the support on the axis of symmetry, the distance between the front edges of the support and the balancing element is from 0.14 to 0.15 the distance from the front edge of the balancing element to the point of its support. The balancing element and / or the support may be provided with limiters for tilting the balancing element relative to the support.

On the support, tilt limiters can be made in the form of its angles or sides bent upward to a height of 0.05 to 0.13 of the width of the balancing element.

Through holes can be made in the balancing element, into which the inserts are installed with the possibility of their reciprocating movement relative to the balancing element when the latter is swayed. Between the balancing element and the support, position sensors of the balancing element relative to the support can be installed, configured to provide an audio or light signal. Between the balancing element and the support, position sensors of the balancing element relative to the support can be installed, configured to control the computer (positioning the cursor on the monitor screen, opening the context menu, executing other commands).

According to the second embodiment of the overhead seat, the task is solved, and the technical result is achieved due to the fact that the overhead seat contains a balancing element and a support, and on the latter there is a rack with a hinge through which the support is connected to the balancing element, while the contour of the platform of the balancing element is formed in terms of conjugation of 3 arcs of circles and 3 straight lines tangent to arcs, with two straight lines forming side edges, and the third straight line forms the front edge ku, while the depth of the balancing element is 1-0.75 of its width, the fulcrum of the balancing element on the hinge is located on its axis of symmetry at a distance from its leading edge of 0.35 to 0.45 of its width, the distance from the support to the balancing element at the location of the hinge, it is from 0.07 to 0.125 of the width of the balancing element, the support is made with a leading edge with an arc of a circle with a radius of 0.45 to 0.5 of the width of the balancing element, the trailing edge of the support is made straight and the side edges of the support are made with the edges bent towards the balancing element with a height equal to from 0.1 to 0.13 of the width of the balancing element, while the width of the support is from 0.7 to 0.8 of the width of the balancing element, and the hinge with a stand is located along the axis of symmetry of the support at a distance from the front edge of the support from 0.25 to 0.30 of the width of the balancing element, while the depth of the support is from 0.6 to 0.7 of the width of the balancing element. Through holes can be made in the balancing element, into which the inserts are installed with the possibility of their reciprocating movement relative to the balancing element when the latter is swayed.

Between the balancing element and the support, position sensors of the balancing element relative to the support can be installed, configured to provide an audio or light signal.

Between the balancing element and the support, position sensors of the balancing element relative to the support can be installed, configured to control the computer (positioning the cursor on the monitor screen, opening the context menu, executing other commands).

The hinge design provides sufficient freedom of rotation of the balancing element in the vertical and horizontal planes. The support of the overhead seat is made taking into account the greatest stability and the contact area of the support with the seat of traditional furniture for seating of various kinds. The support form of the movable seat is related in plan to the shape of the balancing element. The edges of the support along the contour are rounded from bottom to top to avoid tearing upholstery of the chair seat (chair).

To ensure comfortable biomechanical capabilities of the conditions of a sitting person, the range of motion The balancing element of the overhead seat must be at predetermined intervals. For this purpose, limiters for tilting the balancing element relative to the support can be installed on the balancing element. Structurally, the stops are made in the form of separate or continuous protrusions on the balancing element or support, including in the form of its rounded and bent up sides or corners. The values of the angle of inclination of the seat, under which conditions are provided that are comfortable for human biomechanical capabilities, are: forward up to 16 °, back up to 5 ° and on the sides up to 10 ° (in case the balancing element is made concave, the angle between the tangent to the arc of the circle of the concave balancing element at the fulcrum) from the horizontal.

In some models of traditional furniture for seating, there is a reverse (towards the back) 4-5 ° seat bias. For such chairs (armchairs), the design of the movable seat can be supplemented with which the maximum angles of the balancing element are preserved, which are comfortable for the biomechanical capabilities of the sitting person, for example, the placement of an additional pillow filled with fluid or bulk material under the support, or the addition of the movable seat with a structural element compensating for the change in the angle of installation of the support.

In the course of the study of the available developments of various kinds of chairs and armchairs with a movable seat, it was revealed that they are narrowly specialized devices, which complicates the possibility of their use in everyday life, at work, in schools, etc., namely, where it takes place sedentary the sedentary nature of production activities, for example, scientists, operators of personal computers and automatic process control systems, etc.

The seat in the form of an overhead device, which takes up little space, makes it easy to use in everyday life and at work. The simplicity of design with a minimum number of movable joints (only one hinge) makes the device extremely reliable and convenient to use. In the course of ergometric and ergonomic studies, the optimum dimensions of the overhead seat and its elements were experimentally established, which allow it to be installed on almost any chair, whether it be a chair from a home headset or an office chair or chair.

It was found that the rectangular or near-rectangular shape of the trailing edge of the balancing element hitting corners behind the back of the chair prevents it from rotating primarily in the horizontal plane, or scratches the back when rocking. An even more difficult situation occurs when installing a seat with this form of the balancing element In the armchair. The depth of the balancing element is from l to 0.75 of its width and is determined experimentally by the same factors as its shape.

Another set of sizes, namely:

- the distance from the front edge of the balancing element to the support, comprising from 0.35 to 0.45 of the width of the balancing element at an equal distance from the sides, the distance between the front edges of the support and the balancing element is 0.14 - 0.15 from the distance of the front balancing edges element to its support and the ratio of sizes in terms of support with a balancing element of 0.8-0.9, were determined experimentally in studies involving a representative number of people. With other values of the considered parameter, the seated ones show greater tension and inconvenience while maintaining equilibrium. This is manifested in the fact that, at a short distance, the leading edge of the balancing element exerts excessive pressure on the thigh muscles, and at a large distance, it cuts into the lower leg under the knee. In both cases, a person experiences discomfort even with a short sitting on an overhead seat;

- the distance between the balancing element and the support is from 0.07 to 0.125 of the width of the balancing element. The value obtained by calculation and verified experimentally. It has been established that, at lower values of the hinge height, first of all, the front edge of the balancing element touches the front edge of the support or seat of the chair. The effect of free balancing of a person disappears, because two points of support arise. The values of the height of the hinge more than indicated are inappropriate, because the height of the entire overhead seat increases;

- the height of the tilt limiters of the balancing element, made on the support in the form of its rounded and bent up the chord connecting the edges of the curve, the corners, was also obtained by calculation and verified experimentally. The height is from 0.1 to 0.13 of the width of the balancing element, subject to the previous parameters. At the same time, the width of the support should be 0.7 - 0.8 of the width of the ball of the “main element, and the support can be made (second embodiment overhead seat) with a leading edge rounded in an arc with a radius of curvature equal to 0.45-0.5 of the width of the balancing element, and the distance from the front edge of the support to the location of the hinge on the axis of symmetry of the support is from 0.25 to 0.3 from the width of the balancing element, and the depth of the support is 0.6 - 0.7 of the width of the balancing element. The rounded corners of the support bent upward with the dimensions of the support indicated above make it possible, firstly, to install it on the seat of a chair or chair with soft upholstery, and secondly, together with the hinge, provide an angle of inclination of the balancing element relative to the support, which should not exceed the maximum permissible value at which the user will feel inconvenience and provide the minimum allowable distance of the balancing element from the seat of the chair and the chair on which the laid-on seat is installed, so that element is not rested on the seat of a chair or armchair in limiting its tilted state.
