Description

Technical field

The proposed utility model relates to furniture designed for sitting for work or leisure and having functional orthopedic capabilities that allow individual adjustment of support parameters for each user's back with the intention of preventing and treating spinal diseases.

State of the art

A wellness chair is known from the prior art (see RU 2408247, class A47C 1/02, publ. 2011 [1]).

A well-known technical solution relates to furniture for seats with a changing configuration of the surface of the seat and back, preventive and health purposes.

This wellness chair contains a base with supporting surfaces of the seat and back, and has the functional ability to change the configuration of the supporting surface of the back with the technical ability to reciprocate and adapt to the anatomical features of a sitting person.

Wellness chair [1] is an integrated system containing a set of parts that have preventive and wellness functions.

In the known solution, the support surface of the seat is a curved spring-loaded base, partially divided lengthwise into two independent movable sections, and the support surface of the back is similarly made curved and spring-loaded and also partially divided along two independent movable parts, which in the upper part form a convex headrest.

When using this chair by the user, it is not possible to fix an anatomical comfortable position for a certain type of activity (rest, work at a computer or working with documents), since the said independent sections and parts constantly change their position under the influence of the user's body, providing mainly non-orthopedic therapeutic effects, but only massage.

In addition, this design has a complex shape and non-standard parts and elements, therefore, it is quite difficult to manufacture and therefore has a high production cost, the well-known design will require scheduled maintenance and repair of the applied elastic elements, the properties of which are unavoidable during operation are getting worse.

A functional chair is known in the art for reducing fatigue of the human spine (see KR 100788108, class A47C 3/18, publ. 2007 [2]).

Known chair [2] contains mounted on a wheel support base, forming a seat and back. In this case, the backrest is made in an anatomically curved shape imitating the human spine and contains orthopedic elements horizontally arranged one after the other and mechanically adjustable independently of one another, which hug the fragmented back of the user.

Under the adjustment of these orthopedic elements is meant the possibility of their movement and fixation along the height of the backrest [2].

The disadvantage of this development should be considered very low functionality regarding the settings of the back of the chair, since these orthopedic elements can only move in height and are not able to change their position "in depth" of the installation, which makes it impossible to successfully adapt to any user and, accordingly, reduces preventive and Wellness opportunities of this device.

You should also pay attention to the feature of the chair rotating around its axis and the installation of its seat on an elastic damping element that smooths out vibrations, to a certain extent improves ergonomics and ease of use, but at the same time, in some cases, it can have a negative effect on vision, t .e. increase eye fatigue when reading documents on a statically installed screen.

The closest analogue of the proposed utility model is a chair for individual and ergonomic adjustment of the supporting surface of the back (see NO 325146, class A47C 7/46, publ. 2008 [3]).

The well-known ergonomic chair (piece of furniture) is made with the possibility of individual adjustment of the backrest for a specific user and comprises a seat and backrest equipped on a supporting base, which are made in the form of support elements arranged in series with a predetermined interval, while the said support elements forming a backrest are made with the possibility of independent movement , including towards the back of the user, with the provision of orthopedic effects.

In this technical solution, the supporting base is made of two main interconnected parts. On one of the parts a seat is installed, which is made of one large supporting element, and on the other part is a backrest, which consists of several small supporting elements.

As disadvantages, it is advisable to note the ill-conceived design of the supporting base, which is composite and very conditionally imitates the human spine, thereby not forming a single unified orthopedic surface that uniformly and anatomically correctly fits the user.

It is also important to indicate that the supporting elements of the back are located at sufficiently large intervals relative to each other, which individually may have some local orthopedic effect, but not in the complex, since there is essentially no necessary integral surface of the back, in addition, the supporting elements and backs and the seats, apparently, are made soft, which does not contribute to an effective orthopedic effect, but only creates conditions for convenient and comfortable use without the proper preventive or health-improving effect.

Utility Model Disclosure

The technical problem of the proposed utility model is the creation of an ergonomic piece of furniture (chair, chair) designed for seating, which has the ability to individually customize its orthopedic work surface to the anatomical features of each user in order to obtain a sustainable healing or preventive effect.

It should also be noted that the purpose of the subsequent description of the proposed utility model is not to limit it to a specific implementation or example of implementation, but rather to encompass valid additions that do not go beyond the presented formula of the utility model.

The proposed furniture device for seating is made in the form of an orthopedic chair, which has a customized setting.

The orthopedic chair contains 2 seats and a back equipped on a supporting base.

In this case, the seat and backrest are made in the form of a set of supporting elements 3 and 4 arranged sequentially at a certain interval. The supporting elements 3 form the backrest and have the ability to adjust, namely, independent movement relative to each other with subsequent fixation. The supporting elements 4 form a seat and are unregulated, i.e. installed motionless.

The supporting elements 3 and 4 are made of curved wooden material with the possibility of partial anatomical coverage of the user's body.

Support elements 3 and 4 can also be made individually under the "impression" of the back of the user and be asymmetric about the central axis for the purpose of treatment or prevention of a disease such as scoliosis.

The supporting base 2 is made in the form of a single part.

The supporting elements 3 of the backrest and the supporting elements 4 of the seat are designed and located on the supporting base 2 so that they form a unified integral (single) structure with the formation of an individual relief surface, providing a stable and effective orthopedic action.

The most important feature of the device for sitting is that the supporting elements 3 are independently adjustable, namely, they are moved and fixed on the supporting base 2 by means of individual reversible elements 12, which allows creating therapeutic relief working surfaces, adjusting to the anatomical parameters of specific users. In addition, there is a technical possibility after time to change the settings, adjusting to the circumstances, and to change the position of the supporting elements 3 to achieve the optimal preventive or therapeutic effect. This is done through the regulator 13 of the reversing element 12.

As the reversing element 12, a sliding adapter can be used installed in the groove-guide 10 of the supporting base 2. As mentioned, the adjustment (movement and fixing) of the supporting element 3 is carried out by means of a regulator 13 made of a rod with a threaded surface, which is installed at one end with a hole the thread 11 of the supporting base 2. The backrest supporting member 3 is attached directly to the reversing member 12 by a connection 14.

The seat supporting elements 4 are attached to the supporting base 2 with an adapter 15, which has a fastening element (protrusion, latch) 16 for fixing in the supporting base. The adapter 15 fits into the groove 8 and is fixed by connecting the fastener 16 and the hole 9.

The supporting base 2 is usually made in an arcuate shape and conditionally simulates the human spine in the upper part, and in the lower part contains a groove 7 and a hole 6 for connecting to the adapter 5, which is essentially an intermediate part between the wheel device 1 and the directly supporting base 2 as as such.

It is important to note that the wheeled device 2 may have a gas lift (not shown in FIG.), I.e. the chair can be adjusted in height, this is necessary, in particular, so as not to pinch the popliteal artery of the user.

Implemented the proposed ergonomic furniture device for seating with customized settings, as follows.

At the first stage of using the proposed ergonomic device, the user in need of prevention or treatment of diseases of the musculoskeletal system is located on the proposed orthopedic chair as comfortable as possible for his back. In this case, the wooden supporting elements 3 constituting the back and the wooden supporting elements 4 constituting the seat anatomically partially cover the body of the user, which is essentially located on an integral relief surface capable of providing a complex directional orthopedic effect.

Further, for the anatomically correct determination of the optimal parameters (position) of the supporting elements of the 3 backrest, in order to obtain a stable and effective orthopedic effect on the musculoskeletal system, the patient needs to resort to the help of an orthopedic surgeon who organizes the anatomically correct position of the patient on the embossed surface and independently (individual) setting of each support element 3 separately.

As already mentioned above, such adjustment is carried out manually using a reversing element 12, which has the ability to move (slide) in the horizontal direction along the groove-guide 10 of the supporting base 2. To change the position of one or more supporting elements 3 of the backrest, the orthopedist turns clockwise or counterclockwise, the regulator 13 of the reversing element 12, setting the latter in motion and finding the necessary optimal position of one or more supporting elements 3, which will best contribute to the cure or prevention of any disease of the musculoskeletal system.

Thus, it can be conditionally said that the orthopedic surgeon creates a figurative "cast" of the user's back and adjusts and determines the need to configure each supporting element 3, thereby obtaining an anatomically thought-out therapeutic correction surface, each element that has been optimally and standardly adjusted by a professional doctor, which actually forms a high-quality individually configured embossed surface that takes into account the physical and anatomical features of the user.

In the future, the orthopedic surgeon, taking into account the user's diagnosis, gives recommendations regarding the features of using the proposed device for sitting (frequency of use, time of use, etc.)

Also, the orthopedic surgeon sets a date for an additional examination of the user in order to develop further recommendations for the prevention or treatment of diseases of the musculoskeletal system, if necessary, as the spine is corrected, a “repeated” cast of the back and supporting elements 3 of the back are made, can be adjusted again with the purpose of further prevention or recovery.

Based on the foregoing, it is fair to say that the technical problem being solved and the technical result indicated, are achieved due to the fact that the orthopedic device (chair, chair) is customized and contains a base in the form of a single part 2 on which supporting elements 3 are laid with a certain interval of curved shape backrests and 4 seats, which essentially form a unified integral structure that forms an individual, due to the possibility of adjusting the backrest, embossed surface, providing anatomical coverage of the user's body with the manifestation of a stable and effective orthopedic effect.

The proposed ergonomic device for sitting with customized settings can be successfully used for the treatment and prevention of diseases of the musculoskeletal system, both at home and in orthopedic clinics, in hospitals or in rehabilitation centers.
