Description

OFFICE OR HOME CHAIR EQUIPPED WITH MEANS FOR PHYSICAL WARM-UP

FIELD OF THE INVENTION The invention relates to furniture and can be used in the development of home or office chairs that provide increased comfort to the user of the chair, in particular, to reduce the effects of physical inactivity for a long time in the chair. The invention can also be used on vehicles, for example, in long-distance trains, airplanes, buses, as well as in personal vehicles, the owners of which want to have increased comfort on long trips.

BACKGROUND OF THE INVENTION The advent of new technologies related to computers and televisions has substantially changed the working and leisure conditions of the majority of the world's population, and unlike a non-computerized society, it is necessary for a modern person to create conditions for comfortable physical exercises directly at the workplace or at home, mainly in sitting on a chair with a built-in system for performing physical exercises. The chair should ensure its operation, both in normal mode and when performing physical exercises with the regulation of the applied force in accordance with the requirements of the user and with the exception of injury to the user when the physical warm-up is terminated.

Numerous simulators for performing physical exercises in a sitting position are widely known, containing a power base, a seat and fixed on the basis of means for physical warm-up with various types of loaders, for example, pneumatic piston kinematically connected with loaders power levers and various types of control systems of effort on levers, including using computers and other means (see, for example, PCT application JST-. WO 97/45168, A63B 21/008, 12/04/1997). Well-known simulators provide a wide range of effort regulation and allow athletes to develop a particular muscle group, as well as achieve muscle performance at the limit of their capabilities, but cannot be built into conventional chairs.

Simplified training complexes for performing physical exercises in a sitting position are known, containing a chair and a means for physical warming up with elastic loaders such as expanders attached to the chair. To perform exercises on the chair, a number of devices are fixed that interfere with the performance of routine work (see, for example, US patent N ° 5234394, NKI 482/92, 08/10/1993). When using expanders, the physical force is proportional to the expansion of the expander, i.e. changes when doing the exercise. With a sharp release of physical activity, for example, the handle of the expander broke, the user can get hit with the handle. The range of exercises performed is limited to the simplest movements, and when changing the type of load, it is necessary to rearrange the fasteners on the chair.

Also known is a chair containing a base, seat, backrest, armrests, two multifunctional means of physical warming up of hands built into the chair, placed on both sides of the seat, each of which has a device for creating linear force, including a handle fixed to the end of the moving rod , and a device for creating a pumping force, including a swinging power arm kinematically connected with a piston pneumatic loader with a gripper fixed to its end, and a system control efforts on the handles and grips (see US patent JY ° 5755650, NKI 482/138, 05/26/1998). Known chair does not provide the ability to perform physical exercises with legs. In the force control system on the arms of the swing arm, it uses a mechanical change in the length of the swing arm, which allows only a stepwise change in force. The power lever can swing only in one plane (perpendicular to the side edge of the seat), which limits the possibility of physical warm-up of the hands by one type of movement. Separate execution of means for creating a swinging and linear efforts complicates their installation on the chair. All means for creating physical effort are constantly in the working position, which leads to a change in the usual configuration of the chair, and the protrusion of the grips over the armrests limits the movement of the user's hands when performing routine work.

Closest to the proposed invention in terms of essential features is an office or home chair equipped with means for physical warming up, containing a base, seat, backrest, hollow armrests, means for physical warming up of legs and two means for physical warming up of hands built into the chair, each means for physical warm-up of hands it has a hydraulic piston loader and a swinging power lever kinematically connected with the piston loader with a grip fixed at its end. The means of physical warm-up of the legs is an exercise bike installed under the seat of the chair with forward-facing pedals placed on the reclining front wall of the chair (see US patent Jfe 5470298, NKI 482/130, 11.28.1995). Of all the known constructions, this chair is the most suitable for performing physical exercises in a normal home environment or in the office and has the most common appearance for the chair. The exercise bike, like any other friction type loader, provides user safety. Sitting in In this chair, you can perform only one exercise with alternating movement of the legs back and forth, simulating cycling. In the working position, the exercise bike occupies a fairly large space in front of the chair. To bring the exercise bike into working position and to clean it, you need to get up from the chair, which makes this design not convenient enough for the user. The design of the means for physical warm-up of the hands provides only one type of movement "back and forth". Adjustment of physical effort on each of the simulators is carried out independently, which complicates the use of the chair. The fastening of means for physical warm-up requires a special design of the base of the chair, which differs from the usual forms of home and office chairs.

The problem to which the invention is directed is to create an office or home chair that has a familiar appearance and provides increased comfort to the user due to the ability to perform a variety of physical exercises in a sitting position, in which the means of performing physical exercises do not interfere with the use of a chair in normal mode (performing any routine work), and provides a reduced likelihood of injury to the user when performing physical exercises th. Another objective of the invention is the creation of an office or home chair equipped with means of physical warming up of arms and legs, with a high level of unification of its units, including with a high level of unification of means of physical warming up. Another objective of the invention is the creation of an office or home chair, during the operation of which the user himself can choose the most acceptable mode of operation of the chair. Another objective of the invention is the creation of an office or home chair in which, when performing physical exercises, the efforts exerted by the user remain almost unchanged and are regulated directly by the user. An additional object of the invention is the creation of an office or home chair in which the user can adjust the position of the body in the chair by changing the configuration of the back and seat, achieving the most comfortable body position in the chair, both when performing routine work and when doing physical exercises with hands or legs.

At the same time, the receiver is located under the seat of the chair and has two inlets connected to the bottoms of the receiver, a block of boost and vent valves is connected to one of the leads, and a control valve block is connected to the other lead.

In addition, the block of boost and vent valves is located on one armrest, and the control valve block on the other.

The basis of the invention is the implementation of each of the four warm-up devices for arms and legs in the form of a stand-alone module with the installation of stand-alone modules in the hollow armrests of the chair to the right and left of the seat of the chair with the placement of an independent module of means for physical warm-up of the legs in the cavity of the armrest below the stand-alone module of the warm-up device for hands, which allows you to keep the familiar appearance of the chair during routine work, use the standard base and the usual power design of the seat and back, and thereby m not create any hindrance in carrying out routine work. The presence in each of their four autonomous modules of a piston pneumatic loader and a swinging power lever kinematically connected with the piston loader makes it possible to use the same type of arms and legs warm-up devices, which provides a high level of unification of the entire structure of the chair, including a high level of unification of physical warm-up means, which allows the use of a unified system of regulating the force on the swinging arms of all warm-up devices and thereby reduce the likelihood of injury to the user when performing physical exercises. The ability to perform a variety of physical exercises in a sitting position is provided by equipping each autonomous module of a warm-up device for hands with front and rear attachment points to the chair, each of which is made with three degrees of freedom, providing the ability to rotate the autonomous module relative to three mutually perpendicular axes with fixing it in neutral and working positions.

The proposed unified design of an autonomous module of a means for physical warming up, each of which includes a bearing housing, inside of which a piston pneumatic loader is placed, and a swinging power arm pivotally mounted on the outside, provides high structural rigidity, since all loads are perceived by the bearing housing, and a high degree of technological readiness of an autonomous module, since it can be made in the form of a separate unit, completely ready for installation on any chair e. Equipping a piston pneumatic loader with two piston pneumatic cylinders mounted in a bearing housing parallel to each other and pivotally mounted at its end, and a groove cam mechanism that includes at least one disk with two arc slots located diametrically opposite to each other, in each of which there is a finger mounted respectively on one of the rods of the pneumatic cylinders, and the disk is fixed on the axis of the power lever so that each slot is placed symmetrically relative to the longitudinal axis of the lever; when the rods are fully extended, both fingers are located at the far wall of the slots; the pneumatic cavities of the cylinders are interconnected and connected to the input manifold of the control valve block, provides the ability to obtain the force on the lever during forward and reverse swings, and each cylinder will work independently of each other, which ensures the same amount of force on the lever during forward and backward swings.

Equipping the grooved cam mechanism with two discs mounted on an axis parallel to each other, while the piston pneumatic cylinder piston rods are placed in the gap between the disks, increases the kinematic transmission rigidity and eliminates the appearance of lateral forces in the grooved cam mechanism. The implementation of the power design of the piston pneumatic loader in the form of a bearing housing, covering pneumatic cylinders and a cam mechanism, and the swinging power lever is located outside the bearing housing and connected to the cam mechanism disk by an axis passed through the wall of the bearing housing, allows the means for physical leg warming up in the form of an autonomous module.

Equipment of the force control system on swinging power levers with a receiver connected to piston pneumatic loaders and a control valve block located between the receiver and piston pneumatic loaders and including an input manifold to which all piston pneumatic loaders are connected, an output manifold to which the receiver is connected, the return atmosphere intake valve connected to the inlet manifold, parallel mounted check valve for compressed air supply spirit in a receiver and a mode switch valve connecting the input and output collectors to each other, and a controlled pressure control valve in the receiver connected to the output manifold, allowing the user to choose the pressure in the receiver and, accordingly, the level of physical load on the swinging power levers, the maximum pressure in the receiver and pneumatic loaders can be limited by setting the appropriate volume of the receiver, which excludes the operation of the chair with increased forces on swinging power levers, preventing accidental injury to the user.

Placing a control valve block on one of its armrests provides comfortable conditions when setting up a force control system on a swinging power arm.

Equipping the control valve block with a silencer installed at the outlet of the controlled pressure control valve in the receiver increases the comfort level when using the chair.

The implementation of an autonomous module of each means for physical warm-up of hands with a hollow swinging power lever, inside of which there is a device for creating linear force, made in the form of a piston hydraulic loader, the rod of which protrudes above the end of the hollow swinging power lever and is equipped with a handle fixed at its end, while the grip is mounted with the possibility of rotation relative to the swinging power arm with a shift from the worker to the neutral position and fixing it in the specified position x, it allows in addition the load type "swing" to provide the load type "press" - "tolchok" gamut extending loads generated by the proposed remedy. The rotation of the grip relative to the swinging power arm provides a compact layout of the stand-alone module in the armrest and the convenience of hand grip in the working position. The proposed design of the front and rear attachment points of the autonomous module of the means for physical warm-up of the hands provides rotation of the specified autonomous module relative to three mutually perpendicular axes with its fixation in working and neutral positions.

Installing the bearing housing in the neutral position on the pins so that the swinging power lever of the physical warm-up means of the arms extends downward and fixing the grip on the swinging power lever parallel to the bearing body under the horizontal shelf, while the horizontal shelf is made with a bend covering the swinging power lever, provides a compact laying an autonomous module of the means for the physical warm-up of the hands in the cavity of the armrest.

The installation of the bearing body in the working position on the pins so that the swinging power lever of the physical warm-up means of the arms extends upward, and the fixation of the grip on the swinging power lever perpendicular to the bearing body, provides ease of use when performing physical exercises in the first and second working positions.

The proposed design of an autonomous module of means for physical warming up of legs, having a swinging power arm extending downward, a foot support mounted to move along the swinging power arm with rearrangement from the worker to the neutral position and fixing it in the indicated positions, while the bearing body is fixed in the armrest cavity at the seat level of the chair, provides increased comfort to the user due to the release of space in front of the seat of the chair from any speakers beyond ly seat elements, including footholds.

Placement in the working position of the leg support on the lower part of the swinging power arm with the orientation of the supports for the right and the left legs on the levers towards each other makes it possible to move the leg supports to the position in front of the seat of the chair, which provides the user with comfortable conditions when performing physical exercises, as the legs continue to be in the usual position relative to the seat. Moving the supports to the working position and fixing them does not cause difficulties, since the user can perform these operations simply by bending forward without getting up from the chair.

Placing the leg supports in the neutral position on the levers with the orientation of the legs for the right and left legs parallel to each other and the side edge of the chair seat allows the user to remove the legs in a neutral position without standing up from the chair, just bending forward.

Equipping the chair with inflatable cameras located in the seat and back, each of which is connected to the receiver of the force control system on the swinging power levers through the block of boost and air vent valves, allows the user to achieve the greatest comfort in maintaining the body in a sitting position, as when performing routine work, and during physical warm-up due to the use of air in the receiver serving the pneumatic loaders.

A chair in which the receiver is located under the seat of the chair and has two inlets connected to the bottoms of the receiver, a block of boost valves and air vents is connected to one of the leads, and a control valve block is connected to the other lead, which improves the technological characteristics of the chair, so its level increases unification.

The location of the boost valve block and the air vent on one armrest, and the control valve block on the other armrest, makes the chair more convenient due to the spatial diversity of the controls functional purpose.

The rod cavity of each the cylinder is connected to the atmosphere by any known method (drainage hole, lack of stem seal, etc., not shown in the drawing). Both piston cylinders are pivotally mounted on the end wall 35 of the housing 13. The swinging power arm 15 is located outside the housing 13 and is rigidly mounted on an axis 36 passed through the side wall of the housing. The axis 36 passes between the rods 28 and 30 and is connected with them by a kinematic transmission equipped with a groove cam mechanism, including two parallel disks 37, in each of which two arc slots 38 and 39 are made, which are diametrically opposed to each other. The slots are made along the arc sector with an angle of 90 °. The disks 37 are mounted on the axis 36 of the swinging power arm 15 so that each slot is placed symmetrically with respect to the longitudinal axis of the arm 15. The rods 28 and 30 of the piston cylinders of the loader 14 are placed in the gap between the disks 37. The fingers 40 and 41 are placed in the slots 38 and 39, fixed respectively, on the rods 28 and 30 of the piston cylinders. When the rods 28 and 30 are fully extended, both fingers are located at the far wall of the slots 38 and 39. The housing 13 covers the piston cylinders 25 and 26 and the cam discs 37. The front mount assembly 11 of the stand-alone module includes the front bracket 40 mounted on the supporting body, the vertical axis 41, mounted in the bearing 42 on the rear armrest wall 43, and the link 44 connecting the front bracket 40 to the vertical axis 41.

The front support is equipped with a stopper 49, fixing the horizontal shelf 45 and the retractable corner carrier 46 in the retracted and extended positions. The stopper 49 can be of any type (screw clamp, fixing pin, etc.) and its design is not considered in the framework of this application. In the drawing, for illustration, a stopper with a locking pin interacting with the locking holes 50 is shown, one of which is shown in the figure. The horizontal shelf 45 of the supporting corner element is made with a bend 51.

The rear attachment unit 12 of the stand-alone module includes a rear bracket 52 mounted on a supporting body, a vertical axis 53 mounted in a bearing 54 on the rear armrest wall 43, and a horizontal axis 55, the rear end of which is pivotally mounted on the upper end of the vertical axis 53, and the front equipped with a horizontal trunnion 56, on which the rear bracket is mounted rotatably 180 ° without offset along the horizontal trunnion. Each rear attachment unit is equipped with stops 57 and 58 for fixing the corresponding stand-alone module in neutral and working positions. Stoppers 57 and 58 can be of any type (screw clamps, fixing pins, etc.) and their design are not considered within the framework of this application. Bearings 42 and 54 are aligned.

In the neutral position (Fig. 1), the bearing housing 13 is mounted on the trunnions 48 and 56 so that the swinging power arm 15 of the physical hand warming means extends downward and is placed in the bend 51 of the horizontal shelf 45.

Inside the housing 59 there is a piston pneumatic loader, the design of which is identical to the design of the pneumatic loader 14 described above in the autonomous module 9 of the means for physical warm-up of the hands. The casing 59 is made similar to the casing 13 of the stand-alone module 9. Performing identical load-bearing housings 13 and 59 and the piston pneumatic loaders located therein gives the greatest degree of unification of the stand-alone modules 9 and 10. From the outside of the load-bearing housing 59, the swinging power arm 60 downwardly extending is pivotally mounted with the installed on it a support 61 for the leg. The leg support 61 is mounted movably relative to the swinging power arm 60 with the possibility of shifting from a neutral to a working position and fixing it in the indicated positions.

At the output of the controlled valve 72 for controlling the pressure in the receiver, a silencer 73 noise. The control valve block 66 is placed on one of the armrests of the chair, for example, on the right armrest 7. As a switch valve 71 modes, any locking device having two positions can be used: "open" and "closed." As the controlled valve 72, any pressure regulator in front of itself can be used.

The backrest 4, seat 3 and headrest 5 of the chair are equipped with inflatable support pillows 73, the number of which and the layout of them on the chair are determined by the desire of the consumer. Inflatable pillows are usually made of foamed polymeric materials, for example, polyurethane foam, and are closed externally with a layer of decorative elastic material such as artificial or genuine leather, or dense fabric, and have inside inflatable chambers 74 made of an airtight elastic material, for example made of rubber. Each inflatable chamber 74, through a block 75 of boost valves 76 and air discharge 77, is connected to a receiver 65 of a unified system of controlling the force on the swinging power levers. The receiver 65 is located under the seat 3 of the chair and has two inlets 78 and 79 connected to its bottoms. The control valve block 66 is connected to the supply 78, and the charge and discharge valve block 75 is connected to the supply 79. Block 75 valves boost and air vent located on the right armrest 6 of the chair.

In the normal working position of the chair, when the user performs routine work, for example, on a computer, or watches TV, all four means for physical warming up of arms and legs are located inside the armrests and are closed externally by the leaves 8. The swinging power arm 15 extends downward, and the gripper 16 for arms parallel to the side edge of the seat 3. Leg support 61 is located at the bottom of the swinging power arm 60 parallel to the side edge of the seat of the chair. The chair has a familiar look, and nothing prevents the user from doing routine work.

For the period of performing physical exercises (physical warm-up of arms or legs), the user shifts the shutters 8 to the open position. Means for physical warm-up of arms and legs in position sitting, located on the right and left sides of the seat 3, are made of the same type and the following describes the work with two of them located, for example, in the left armrest. All operations for working with means for physical warming up of hands and feet can be carried out by the user without leaving the chair.

To translate into the working position of the stand-alone module 9 means for physically warming up the hands, the user releases the stopper 57, rotates the stand-alone module 9 through 180 ° relative to the horizontal axis and fixes it in this position by the stopper 57 (first working position). The swinging power arm 15 is directed upward, and the grip 16 is parallel to the armrest. Release the latch 19 and rotate the grip 16 inward by 90 °. The grips 16 on the right and left levers 15 will be directed towards each other. In this position, the user can perform several physical exercises. Holding the grip by the hand, the user can swing the lever 15 "back and forth", as shown for the right swinging power lever (figure 2).

To translate into the working position of the stand-alone module 10 means for physical warming up the legs, the user removes the latch 64, expands each of the supports by 270 ° and fixes them in this position.

The user, sitting in a chair, adjusts the controlled valve 72 to the pressure corresponding to the required force, sets the valve switch 71 to the “closed” position and starts working with the swinging power levers 15 or 60. When any power levers 15 or 60 are simultaneously swayed, the pneumatic loaders will work to pump air into the receiver 65, and all the loaders work the same way. After the previous physical warm-up, the pneumatic system will always retain some residual pressure, under the influence of which the pistons 27 and 29 are displaced in the extreme position, as shown in Fig.6 and 8. The fingers 40 and 41 are located at the far wall of the grooves 38 and 39. The power lever 15 can swing back and forth within 90 °. When the power lever 15 is shifted forward, the disks 37 of the grooved cam mechanism are rotated. The finger 40 moves along the circular arc and moves the piston 27 forward, compressing the air in the cavity 31 of the piston cylinder 25. The piston 29 remains in the final position, as the slot 39 is able to move freely relative to the finger 41. Compressed air is pumped through the check valve 70 into the receiver 65 . With the reverse movement of the power lever 15, the piston 29 continues to remain in the final position, and the piston 27 under the action of compressed air in the cavity 31 begins to move in the opposite direction until the pressure in the cavities 31 and 32 is equal to atmospheric, and the piston 27 stops at a certain intermediate position. The power lever 15 continues to move, and the disks 37 rotate with it until the front end wall of the groove 38 comes in contact with the finger 40. With the further movement of the power lever 15, the finger 40 moves together with the disks 37 and moves the piston 27. The pressure in the cavities 31 and 32 falls and through the check valve 69 a new portion of atmospheric air is sucked in. Air injection continues until the controlled pressure control valve 72 in the receiver is activated and physical exercises can be started with a nominal force on the swinging power levers 15 and 60. The mode switch valve 71 is put into the “open” position and the pressure in the receiver 65 and piston pneumatic loaders leveled. Pistons 27 and 29 in all pneumatic loaders move to the extreme position shown in FIGS. 6 and 8. When the power arm 15 or 60 is swinging relative to the neutral position, one of the pistons will always move, reducing the volume of the air cavity in its cylinder. Moreover, in the adjacent adjacent cylinder throughout the cycle of this swing, the air cavity will have a maximum volume, and taking into account the volume of the receiver 65, the displacement of the piston will not lead to a significant change in pressure in the pneumatic loaders, keeping the force on the swinging power levers 15 and 60 unchanged regardless of whether simultaneous or alternating movements are performed by hand and legs. Swings can be carried out synchronously or in antiphase. At the end of the physical warm-up, the swinging power arms 15 and 60 will always be in the neutral position. Holding hands on the handles 24, the consumer can also perform their hands up-down movement. With this movement, the rod 22 makes reciprocating movements inside the swinging power arm 15. The fluid through the nozzle 23 flows from the cavity of the rod 22 into the cavity of the swinging power arm 15 and vice versa. The pressure drop across the jet 23 determines the amount of applied physical force.

To translate the stand-alone module 9 into the second working position, release the stopper 58, turn the stand-alone module around the vertical axis by 90 ° and fix it in this position by the stopper 58. The grips 16 are parallel to each other. Holding his hand in the grip, the user in this working position can swing the lever 15 "left-right", as shown for the right swinging power lever (Fig.Z), expanding the range of physical exercises. Feet can perform the same physical exercises as in the first working position. The work of power loaders in the second working position does not differ from that described previously. Using the handle 24, the user can also perform a hand movement "up and down", similar to the previously described.

To translate the stand-alone module 9 into the third operating position, release the stopper 49 and slide the stand-alone module 9 up, turning the multi-link 44 by a certain angle, for example, by 15 °. A telescoping telescopically connected to the horizontal shelf 45, the extendable corner carrier 46 is moved to the extended position and locked in this position by the stopper 49. The swinging power arm 15 takes an inclined position, which changes the physical load on the hands, expanding the range of exercises. Feet can perform the same physical exercises as in the first working position. The work of power loaders in the third working position does not differ from that described previously. In the presence of inflatable chambers located in the seat and back, the user can control the position of the body in the chair, achieving the greatest comfort. For this, at the block 75 of the boost and air vent valves, the air vent valves 77 are closed and the corresponding valves 76 of the chambers 74 are opened. The air is supplied to the chambers 74 until the body of the user assumes the most comfortable (according to his sensations) position in the chair. All operations are performed by the user directly in a sitting position without deviating the body from a normal posture and, thus, he can directly assess the comfort of placement in the chair. At the end of the exercise, the user returns the autonomous modules 9 and 10 to the neutral position. The user releases the latch 64, expands the support 61 feet on 270 ° and fixes it in this position.

To return the means for physical warm-up of the hands to their original position, the user releases the stopper 49 and lowers the stand-alone module 9 until the bearing case 13 assumes a horizontal position. At the same time, the telescoping telescopically connected to the horizontal shelf 45 extendable corner bearing element 46 is moved to the retracted position and is fixed in this position by the stopper 49. Then the user releases the stopper 58, rotates stand-alone module 9 at 90 °, setting it parallel to the side edge of the seat, and fixes it in this position by the stopper 58. Release the locking catch 16, turn the locking 16, set it parallel to the armrest and fix it in this position. Then, the stopper 57 is released, the stand-alone module 9 is rotated 180 ° relative to the horizontal axis, moving the swinging power lever 15 down, as shown in Fig. 1, the stand-alone module 9 is fixed in the neutral position and the armrest is closed with the shutter 8, restoring the seat to its usual working appearance. There are no obstacles to the performance of routine work.
