Description

The invention relates to the field of industry for the manufacture of furniture for seats, to adaptive system devices of permanent therapy with a changing configuration of the functional surfaces of preventive and recreational purposes used in offices, in production and in everyday life.

The closest analogues are known: invention RU 2199258 C1, A47C, 1/02, 2003; the seat and back of the device are made of two parts, pivotally mounted on horizontal axes, mounted on the base, and equipped with rotation controls. The screws of the regulators fix both parts in a certain stationary state with the help of retaining elements when the spine reaches its characteristic defined twisted position, determined by the method of kyphoscoliosis, thereby allowing to unload the spinal column in a sitting position and to avoid its curvature.

The above invention captures a rigid anatomical cast of a sitting person and deprives him of his freedom to actively change his body position over time. But a person cannot sit for a long time in the same position, namely, one knee will be constantly lowered and the other raised. When changing the posture, reconfiguration of the parts of the seat and back is necessary to prevent tension of the spine, which requires the presence of a second person with a measuring device and for the next fixation of the locking elements. This greatly complicates the operation of the invention, as well as the achievement of the claimed technical result. In addition, only the swinging movement is present in the parts of the seat and backrest and there is no shock absorbing reciprocating motion due to the seat and backrest axles that are rigidly fixed to the base of the chair.

RU 2009658 C1, A47C 7/00, 1991; medical furniture contains a frame that has slots for installing removable inserts in the form of plates of biologically active wood, the selection of the minimum thickness of which and the type of bioenergetic effect on a person and their activity are determined individually by the biolocation effect using a biolocation frame specifically for each given person.

To use such furniture, the constant presence of a specialist possessing dowsing abilities and skills, conducting periodic measurements and selection of certain wooden plates and their thickness for a person’s health status changing over time and for the use of this furniture by another person, or this furniture should only be strictly for individual use, is required . This functionality, which is narrowly focused on various parameters, limits the mass application and limits the operational capabilities of furniture. In addition, sitting on a hard wooden surface for a long time to achieve the claimed therapeutic effect is not at all comfortable.

The technical result of the claimed invention, taking into account, including the disadvantages of analogues, is presented below.

A threat to the health of a huge number of people nowadays is physical inactivity and a sedentary way of working and living. This lifestyle is accompanied by three main unhealthy factors: 1) Acquired sitting C and S-shaped curvature of the spine due to natural asymmetry - hip node hypoplasia, the angle of pelvic elevation is different for the right and left sides of the person. 2) Stagnation in the hip area, leading to sluggish intestines to remove toxins, worsening and impaired circulation. 3) Violation of the temperature balance and air exchange of the pelvis, and in men, also overheating of the testicles, leading to infertility.

To neutralize these factors, the following is necessary. A man with his apparent symmetry is far from symmetrical. Imagine this schematically. On the continuous horizontal surface of the seat, the right and left sciatic tubercles of the hip joint form an asymmetry gap “O”, Fig. 1. The gravity of the body G presses on one of the higher located pelvic bones, forcing it to reach the plane of the seat, while the other is already on it, Fig.2. As a result, an S-shaped bend of the spine is formed along the radius R. The magnitude of the radius depends on the magnitude of the asymmetry-hypoplasia of the pelvic bones and adjacent tissues and ligaments.

Curvature can be avoided by adjusting the seat surface to the asymmetry of the pelvis, Fig. 3, lowering a separate part of the seat under the sciatic tubercle by the clearance value “O”, and it is necessary to achieve automatic adaptation at any time without monitoring from our side, which means distribution and balancing load and pressure on the contacting parts of the body.

C-shaped curvature is prevented by a similar ergonomic set of supporting surfaces for the back, lower back, neck, arms and legs, taking into account the same asymmetry and anatomical lines and bends, but built in accordance with the Akerblom line, based on the locomotor function of the sitting person and representing a stable pattern of his movements sitting.

- Stagnation can be avoided by giving the seat and back the training and massage properties.

- Ventilation will provide access and exhaust air through the supporting surfaces.

The claimed invention on the basis of insertion by its design provides biomechanically asymmetric auto-correction, as well as attenuation of vibration and shock effects, and therefore, the implementation of the above technical results, expanding the arsenal of technical equipment for this purpose.

The healing chair, standard in terms of general ergonomic parameters specified in GOST 21889-76 “Operator’s chair”, contains: a seat, back, armrests and, additionally, a head restraint and supports for the lower back and legs to ensure a proper fit; It is an integral device, inextricably linking together a complex of discrete parts, carrying the preventive and healing functions stated above. The base and all functional surfaces for both seating and support, FIGS. 4, 5, 6, are congruently formed directly only from torsion, compression, tension springs, with special target hooks and sets of removable surfaces-inserts-overlays. So, the seat and back of the chair, figure 4, 5, 6, consist of torsion springs 2, 6 and compression 3, an emphasis on the lower back 5, headrest 1 and armrests 4 - from torsion springs; movable suspended footstool-for legs 7 - from tension springs 7 and torsion 12. Spring hooks, for rigidity, are connected directly to each other by jumpers from a spring wire using couplings 13 or by welding. On top of the retention hooks are mounted interchangeable multifunctional inserts-pads 10, figure 9, in the places of functional contacts with the human body. Connecting together, a transparent, transparent-spatial spring-wire lightweight frame-structure of the chair with therapeutic and kinesitherapeutic properties is formed. Chair materials: spring wire and plastics, wood or composites for surface-planes of functional inserts-overlays.

The planes of the supporting surfaces, FIGS. 4, 5 and 6, can be either solid classic, due to removable inserts, pads, or divided in the sagittal plane of symmetry of the chair into separate, but interconnected parts spring-loaded compression, torsion and tension blocks, providing back - translational movement of the free ends of these parts relative to the base.

Supporting functional planes for the lower back, head restraint, armrests, backs and seats, leg supports include complete sets of additional, multifunctional interchangeable - quickly mounted and dismountable - surfaces directly in contact with a person: corrugated, perforated, with differentiated softness, cork, roller, inflatable, bulk, ring antihemorrhoids and many others, with the possibility of fastening with a groove system - a spike 9, 10, figure 9, or other various simplest ways, where ur wire hook spring 9 is a groove for the supporting surface of the insert lining 10 with a corresponding recess and a quarter along the contour for fixing in it.

The surface of the seat and back, to ensure their controlled forced reciprocating motion, figure 10, may have additional movable connections 11, with the base of the chair through pneumatic gas or hydraulic cylinders, electromagnetic coils or other devices with appropriate drives.

Figure 1, 2 and 3 shows the spinal column of a person with the sacrum and pelvic bones in a sitting position. The sequence of formation of the S-shaped curvature of the spine due to the natural gap of asymmetry “O” of the hip joint, called the angle of the pelvic elevation in medicine, and avoiding the curvature of the seat surface under the sciatic tubercles by its division into separate parts, are depicted.

Figure 10 shows a diagram of the action of a healing chair made of springs under the weight G of a seated person, as well as a diagram of additional controlled movable connections of the surfaces of the seat and back with the base of the chair.

The recovering chair in a static state is a device, Figs. 4, 5 and 6, obtained directly from a set of different types of springs connected together: the base and seat 6 and 3, the backrest 2 and 3, the armrests 4, the headrest 1 and the support for the lower back 5 and for legs 7. Seat 6 and back 2 are divided along the longitudinal axis of symmetry of the chair into separate spring torsion blocks 6 and 2 and compression 3, which include sets of additional multifunctional interchangeable - quick-mount and dismountable - surfaces 10. Free ends of the department ln, but interconnected parts of the seat 6 and backrest 2, may have additional controlled, movable reciprocating connection 11, figure 10, with the base of the chair, which are directly hooks of torsion springs 6 and 2.

The action of the device is as follows: under the influence of the weight of the seated person G, Figs. 3 and 10, the free ends of the separate but interconnected parts of the seat move down, respectively, to the load of the right and left sciatic tubercles to a certain level, balancing asymmetry-hip hypoplasia of the hip differentially by the absorbing force of the spring blocks joint to the necessary clearance "O", thus providing auto-regulation of the position of the right and left pelvic bones in height with any change in body position and in any time. This eliminates the S-shaped curvature of the spine. The individual parts of the backrest 2, by analogy with the individual parts of the seat 6, Fig. 4, provide their movable supporting surfaces on the spring blocks with constant shock-absorbed compensation for the asymmetry of the region of the thoracic spine, which means that torsional stresses in it are removed - muscle stiffness is removed. The purposes of soft strain relief on the spine are also mobile shock-absorbing blocks of torsion springs of the support under the lower back 5 and headrest 1, copying its natural bends. The armrests from the torsion springs 4, Fig. 4, serve the same purpose - the convenience of unloading the muscle tension of the spine and the prevention of C-shaped curvature, as well as the movable suspension foot-bearing 7 for legs from the tension and torsion springs.

The sets of additional, multifunctional interchangeable - quick-assembled and dismountable - surfaces 10, Fig. 9, which are in direct contact with a person, provide with their design features the preventative-health complex: - thermoregulation and natural air exchange provide perforation and gaps between the rollers, - massage provides corrugation and rotating rollers; - the simulator provides reciprocating movement vertically and horizontally on the roller surface, rolling and wavy.

Forced controlled reciprocating movement of the individual parts of the seat and back provides a kneading effect, the elimination of congestion and stimulates blood circulation, as in massage and exercise.

Vibration and shock loads are damped by all shock absorbing bearing surfaces of the chair.

Completing the chair with a swing-lifting mechanism with a swing mechanism and a mobile rack with a cross on wheels can be standard, or can be supplemented by spring units from torsion springs with corresponding closed support hooks, Fig. 8, and additional controlled movable links between each other. The attachment point 8 of the rack to the chair is shown in Fig.5.

Corrosion-hygienic and aesthetic processing of spring wire can be any one used in industry, namely: from powder coating and enamel painting to gumming, electroplating and other things like that.

A healing chair is industrially applicable; and in the part of winding the springs and in the part of the molding-molding of the supporting surfaces.
