Description

The utility model relates to the field of satisfying human needs and relates to the constructive implementation of the device used to support the head of a worker who sits in front of a computer for a long time. The utility model allows a working person (for example, an online game player, an office worker in the data entry service, a programmer, just relaxing, watching TV shows and movies, etc.) to correct posture, correct vision, relieve or reduce tension from the neck and shoulder girdle and maintain tone during prolonged sitting at the table working on a computer.

Modern living conditions and livelihoods place increased demands on the adaptive reactions of the human body. The rate of change of natural, technogenic and social environments is several times higher than the possible rate of adaptation of the body, which inevitably leads to a breakdown of adaptation mechanisms and the development of diseases. Recent studies and observations in the field of health protection have shown that the majority of people working at a computer have a visual impairment, posture, musculoskeletal system, etc. Moreover, functional disorders of the musculoskeletal system are combined with unstable autonomic regulation. Surveys revealed a lack of preventive measures aimed at preventing violations and diseases in this area. Non-observance of security measures, sanitary norms and rules, lack of rational furniture leads to the formation of improper posture and violations of the static-dynamic stereotype (moven patterns), reduced concentration, development and manifestation of attention deficit disorder, and decreased vision.

Despite the fact that norms have been developed on the position of the parts of the body of a person sitting on a chair in front of a table while working on a computer (for example, you need to look at the monitor from an arm’s distance, and its upper third should be at the eye level of the person working. Legs under the table should be The legs should be on the floor so that the feet are parallel to the floor. Put your feet on the floor completely, not just the tips of the fingers. Hands and forearms are on the same line. The back is straight and has support. The eyes look only forward, etc. (Fig. . 1) whose fulfillment would reduce the negative impact on the body of the worker, in reality, these requirements are not met.

With the back position straight, and the eye at the monitor level (with straightened shoulders and neck), the keyboard should be located at the level of the abdomen and next to the human body. In this position, the worker sees the monitor screen, but does not see the keyboard. That is, you can only work on the keyboard in a "blind" way, which is essentially unrealistic (there is no centralized learning system for using the keyboard in "blind", while there is no clear standard for the layout of all buttons in the keyboard, which makes the learning system ineffective for changing keyboard types its use in work). It is rather difficult to keep the hands on the forearm line with a straight back for a long time, the hand requires support and relaxation of the forearm, etc. If we take into account that for choosing a chair and a table for a worker, it is not possible taking into account the anatomical structure of the worker, then the worker himself adapts to the workplace and transforms the pose towards the convenience of working on the keyboard, if possible see both the keyboard and the monitor screen (Fig. 2). Our “computer” time forms peculiar deformations of the neck statics associated with the static position of the head in front of the computer screen. In this case, the head is extended forward. Following the head, the neck stretches, provoking excessive tension of all its muscles. The depth of the jaw line decreases, leading to a chamfered line of the chin. Overstrain of the sternocleidomastoid (GCS) muscle occurs, swelling of the lymph nodes under the jaw arch, loss of its clear line. The entire internal structure is the larynx, the hyoid bone also moves forward. If there is such a problem, basic relaxation techniques will not help to adjust the neck. “Computer neck”, as a special product of civilization, requires specific specific techniques (Art. “Correction of the“ computer neck ”, June 21, 2015, posted on the Internet at: http://www.liveinternet.ru/users/irzeis / post365110763).

Statistics say that pain occurs in about 30% of office and other workers whose day is spent in a sedentary state. Experts say that anything can hurt - not only the back, but also the neck, shoulders, arms, legs and even feet. The whole reason for the lack of movement and constant sitting in one place. Due to such work, acid accumulates in our body, which provokes muscle atrophy. In itself, the substance is safe, on the contrary, it is necessary for the body to release the accumulated energy. But during the working day we do not need this energy. In order to avoid “stagnation” and pain in the back and neck, first of all, you need to at least minimally change your position every 20-30 minutes.

The chair must have a comfortable back, with a natural bend. There should be no gap between the back of the chair and your back. The back must be kept straight, it is even better to lean back, it will take on part of the load of the spine. Shoulders should be straightened (article "How to work properly with a computer", posted March 4, 2012 on the Internet at: http://www.liveinternet.ru/users/irzeis/post209527938).

In this regard, devices appeared on the market to maintain the head of the worker and preserve vision, the purpose of which was to keep the position of the head at a given distance from the monitor screen or book. Initially, these devices were made for children and schoolchildren with the goal of protecting their eyesight by forcing the head to be held at a distance from a book or screen.

So, it is known a device for supporting the head of a worker sitting in front of a computer, containing a lodgement for supporting the chin of a worker in a sitting position in front of a computer, a support element on which the lodgement is mounted and which serves to hold the lodgement at a distance from the working table, and a support unit for supporting the support element on the working desk (see laid out on the NAZYA website on the Internet at: http://nazya.com/product/podstavka-dlya-golovi-changing-attatude-treasure-instandard-edition_3508345139.html, found in 2015 .) (copy attached). This decision is made as a prototype.

This device is made entirely of polymer. The lodgement is made in the form of a concave element mounted on a telescopic support telescopic support member having a nut for tightening the upper part after it is extended to a predetermined height. And the node supporting the supporting element on the table b is made in the form of a polymer clamp with two fixing screws. The design of the device is made lightweight based on what will be used for the child. This design does not have a bearing capacity so that it can be used for the head of an adult. Polymer telescopic rods in the nut fixing mode operate due to the friction force between the contacting surfaces of the lower and upper parts of the support element. Over time or frequency of use, this interaction loses the ability to fix the elements of the rod and under load, the extendable part begins to fail at the moment the head is applied to the lodgement. In addition, based on the anthropological parameters of the child, the telescopic rod is mounted at an angle from the table towards the child. This leads to the fact that the tilting moment always acts on the rod, leading to the separation of the rod from the twin-screw clamp. Naturally, for an adult, such a design is incompetent, since it cannot hold the load on the weight of an adult. In addition, the well-known design is more suitable for such an action as reading a book, this is indicated by the inclination of the supporting element (bar) from the table towards the reader when he is sitting on a chair with a straight back. This pose is not used when working at a table on a computer, since the position of the head of the worker is close to the edge of the table or is above the table.

This utility model is aimed at achieving a technical result consisting in increasing the durability and reliability of a device for supporting the head of a worker or resting while sitting in front of a computer by forming a developed support of this device on the table surface and keeping the projection of the center of gravity of the head on the table in the reference rectangle, the edge points of which are the points of support of the legs of the device.

The specified technical result is achieved in that in the device for supporting the head of the user sitting in front of the computer, containing a lodgement for supporting the chin of the person working in a sitting position in front of the computer, a support element on which the lodgement is mounted and which serves to hold the lodgement at a distance from the working table, and the node supporting the support element on the table working, the support element is made in the form of two U-shaped rod elements, the shelves of which are parallel and opposite d friend, the legs of one of the U-shaped form of the core element are located at the intersection of the legs of the other U-shape of the core element, while at the intersection of the legs on each side of the shelves are pivotally connected to each other, and the lodgement is made in the form of a flexible and deformable strip connected with U-shaped shelves of core elements.

In this case, to prevent slipping on the table, the free ends of the U-shaped rod elements are equipped with high adhesion material terminators or the free ends of two intersecting U-shaped legs of the rod elements are equipped with attachment points for these legs to the table edge, each of which is made in the form of C -shaped bracket placed on the edge of the table and having a screw for clamping the bracket to this edge.

To provide the possibility of regulating the shape of the lodgement, a flexible and deformable strip is fixed on one shelf, and its other end is wrapped in a second shelf and attached to the back of the strip by fastening with Velcro. And in order to regulate the height of the lodgement, one of the hinges of the legs of the U-shaped rod elements is made with the function of fixing the angular position of the legs when changing the angle of their inclination relative to each other.

These features are significant and are interconnected with the formation of a stable set of essential features sufficient to obtain the desired technical result.

This useful model is illustrated by specific examples of execution, which, however, are not the only possible ones, but clearly demonstrate the possibility of achieving the desired technical result.

According to this utility model, the design of the device is considered, which is used by a worker or a rest sitting at a table as a device for holding (maintaining) the head. This device is used mainly for prolonged use at a computer.

In general, this device for supporting the head of a user sitting in front of a computer includes a lodgement 1 for supporting the chin of a person sitting in front of the computer and a support element 2 on which the lodgement 1 is mounted and which serves to hold the lodgement at a distance from the working table. The supporting element is performed with the node of its support on the table working.

For all examples of execution (Fig. 1 and 2), the supporting element 2 is made in the form of two U-shaped rod elements, the shelves 3 of which are parallel and opposite each other, and the legs 4 of one of the U-shaped rod elements are located with the intersection of the legs another U-shaped rod element. At the intersections of the legs on each side of the shelves by a hinge 5 are interconnected. There are two possible examples of the device. In the first example, the legs 4 are made in the form of rod elements calmly resting on the table (Fig. 3). In the second example, the legs in the zone of support on the table can be interconnected by cross members 6.

One of the joints 5 of the connection of the legs of the U-shaped rod elements is made with the function of fixing the angular position of the legs when changing the angle of their inclination relative to each other. Swivel of intersecting legs means a horizontal hinge in the form of an axis passing through the through and aligned holes in the legs. In fact, such a hinge can be a bolt passed through the holes and fixed with a nut (for example, in the form of a lamb). When the nut is loosened, it becomes possible to change the angle of inclination of the legs, after choosing the angle, tighten the nut and fix the position of the legs, in which they cannot spontaneously move apart when a load is exerted on the cradle (from the head).

The free ends of the U-shaped form of the rod elements are equipped with terminators 7 of a material with high adhesion (for example, latex rubber). The use of terminators, worn on the free ends of the legs, eliminates slipping or displacement of the device on the surface of the table or under the load of the head or due to rotation of the head. This example of the use of terminators is used for the example of the device of FIG. 3, which shows that the legs in the lower part are not connected. For the free ends of the legs such terminators can be made in the form of caps put on the legs. The terminators of the same function can be attached to the cross members for the example device of FIG. 4. For this example (Fig. 4), the terminators can be made in the form of rings or clips.

The embodiment of the device of FIG. 3 (with free ends of the legs), in which the free ends of two intersecting legs of the U-shaped rod elements are equipped with attachment points of these legs to the edge of the table, each of which is made in the form of a C-shaped bracket 8, worn on the edge of the table and having a screw 9 for clamping the bracket to this edge (Fig. 5). By design, each such attachment assembly is a clamp. Two legs from one long edge of the lodgement are equipped with clamps, and the other two legs are made with terminators. At the same time, there is no need to use an adjustable hinge at the points of intersection of the legs, it is quite simple to ensure the possibility of free rotation in these places. The function of fixing the legs in a given angle (adjusting the device in height) has been transferred to clamps. When placed on the table, the legs with the ends are freely installed on the table surface, and the legs on the other side of the lodgement with clamps are placed at the edge of the table. They bring the edge of the table into the cavity of the clamps and extend the legs to select the desired height of the lodgement. Then tighten the screws in the clamps. The worker at the table lays his chin on the lodgement (Fig. 6).

The lodgement is made in the form of a flexible and deformable strip 10 associated with the shelves 3 U-shaped rod elements. A flexible and deformable strip is fixed on one shelf, and its other end 11 is wrapped in a second shelf and attached to the back of the strip by fastening with Velcro or other fastening means, which allows to reliably connect the end of the strip to the surface of the same strip. The strip may be made of woven or non-woven fabric. For this example of its execution, one edge of the strip is wrapped and 12 is sewn across the strip at a distance from the inversion line to form a channel. This edge of the strip is put on the leg and stretched to the shelf. The other edge of the strip is equipped with Velcro, is wrapped in another shelf and the free end 11 of the strip 10 is attached to the lower surface of the strip (Fig. 7). Since the Velcro has a high grip and does not deteriorate when repeatedly disconnected / connected, its use allows you to adjust the depth of sagging of the lodgement when pushing or moving the legs (adjusting the position of the lodgement in height).

This utility model is industrially applicable and can be manufactured in mass production using standard machining technologies. The novelty of the claimed utility model consists in the reliability and durability of the device for supporting the head of the worker due to the fact that the design of the device is quadruple with the formation of a supporting quadrangle in the projection onto the table surface, in the area of which lies the projection of the center of gravity of the head of the worker. With this design, regardless of the movements of the head or movement of the shoulders and regardless of the weight of the body part falling on the lodgement, the device is not subjected to displacements and movements on the table, not only due to the use of adhesive end fittings, but due to the fact that the projection of the center of gravity during natural movements of the head the head will always be in the perimeter of the support legs.

The design of the device is simple to manufacture and can be made of a bent metal or polymer tubular profile using bolted joints at the intersection of the legs. The device gains light weight and the ability to fold when loosening the bolt connection due to the information legs. The device allows you to correct posture, correct vision, relieve or reduce stress from the cervical-shoulder girdle and maintain tone during prolonged sitting at the table working on a computer or while watching movies and TV shows.
