Abstract

An exercise machine with spiral springs designed for performing all movements. The exercise machine has a small size but high in efficiency, and can be used at home and all public places. In this machine by utilizing spiral spring the force needed for movement, is derived from leather band spring and the friction between cloth leather band and fully leather band. A special mechanism is considered to adjust the machine force so that the work force can be varied by the user without weights.

Description

BACKGROUND OF THE INVENTION

In previous inventions related to exercise tools, the machine force changes with weights and causes them to be heavier, and the force remains fixed in machine springs which is used to perform movements. As a result, it is not possible to use them for different movements by different users. However, in this invention both the weight and volume has been reduced and force is adjustable so that various movements can be performed using the same machine.

SUMMARY OF THE INVENTION

An exercise device has been designed for medical body movements in low weight and volume with a high efficiency. The force utilized is from the energy of spiral springs and friction resistance force. Mechanism has been installed on the machine for force adjustment. The electronic power of this machine has been updated such as different data like number of movements, work force, speed, and time has been designed.
This machine is specially used in physiotherapy and rehabilitation centers and the basic performance of this machine is like the previous one. The only difference is that unlike conventional exercise machines, where the user used to stand, a wheelchair/special chair has been located so that the user can sit and do his/her work-out there.

VARIOUS PARTS OF THE INVENTION AND THEIR PERFORMANCE

Lack of exercise and an increase in illness has a direct effect on the economy and a reduction on peoples' spirit. The migration of people to cities and increase in city population and the reduction of living space and all the limitations of living in an apartment, has all led to a dissatisfying life for most people around the world.
On the other hand the increase in activities, social and occupation has caused these people to avoid using public places for exercise so physical and mental illness has increased in modern life. To help remove this problem in offices and homes the designers have tried to build some machines in order to be used inside houses as well as offices. This invention also has the same objective so that it can cover many movements in low volume and it replaces many heavy machines.
Its special type can also be used in rehabilitation places and sport medicine. In this machine the force needed for performing movement is provided by leather band spring and the friction between cloth leather band and pulley leather band.
The transformed force from user's muscles to internal parts of the system is done by the cable. This makes the leather band spring recollecting and creating friction between the cloth and pulley leather band, which helps resist against the force initiated by user's muscles.
In this system the force exchange mechanism 2 is also considered, which helps users to adjust the force for different activities. They can adjust by moving the handle so that leather band springs 22 recollect and the turning angle increases. On the other hand the friction between cloth leather band 51 and pulley leather band 19-7 also increases and as a result, this will increase the resistance force against different movements.
The overall system is designed in the way so that adjusting force causes a wide variety of sport movements. Therefore the people can use this machine at different places. In this machine the electronic part 4 is used which helps to show different kinds of information such as the number of movements, force, the speed of movements, and others. This kind of information can help motivate the users a lot.
Using spiral springs in conjunction with friction force and also employing force exchange mechanism without using weight can decrease the overall weight of the machine. The system has been designed in a way so that it can be used in three different altitudes and cover upper part body movement as well as lower part body movements and all the people in a group can use it. A special type of this machine can be used in physiotherapy and rehabilitation centers different components of the inventions.
In this design, electronic parts are employed to control the functionality of the device better. Many important movement parameters can be displayed by the monitor. Also, the machine is capable of sending movement information to the physiotherapist's computer.
To increase efficiency, four parts have been used. Force adjustment is done through entering force in electronic panel 67. A dynamo of dc 61 along with a gearbox 58 is used. Through entering the amount of required force in the panel by the user, performance can be analyzed in the program. Then the dynamo is enacted and using the gearbox the force is transmitted to the wheel by chain 60 in 1/40 rate. As a result, the drupe 4 starts turning. On top of the drupe 4 spools are coupled and a cable 62 has been installed on every spool, which helps the outer bowl work. As soon as the drupe 4 turns, the spools start turning as well and the attached cables cause the band spring to recollect and the loaded force of the spring increases.
The user can perform different activities with an adjusted force. This force is adjustable from 1 kilogram to 30 kilogram in 100 gram intervals. To adjust force, the user inters the required force in panel using buttons on the panel. The programs designed for the system analyzes the data and determines the number of turns made by dynamo to provide the needed force.
The dynamo starts turning and after completing the required turns it stops and the user can start performing various movements. This system is capable of showing the speed, acceleration, and the number of turns in the digital monitor. This is of high significance from medical point of view. To perform this aim, different sensors have been employed and transmit data to the electronic part. Through the defined program, the data is analyzed and will be displayed on the digital monitor.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

When operating the device, the user can pick up handles 1 in three altitudes and start doing various movements. The exercised force by the user enters cables 5 by handles 1 and this force is transformed to internal pulley 19-2 by the cable 5. This pulley is attached to internal shaft 19-1. The spiral spring 22 is attached to this shaft from inside and to the cover 19-3 from the outside. Over this pulley shaft the friction band 19-7 is placed and over the pulley the friction band 51 is placed. This is attached to the pulley 19-2 on one side and on the other side to a fixed body 8. So the cable force moves to the pulley 19-2 and to the spiral spring 22. Through the internal shaft 19-1 and to the friction pulley 19-7, which causes recollection of the spring and creation of resistant's between cloth band 51 and friction pulley 19-7. As a result it can resist the force made by the user.
During every movement this process is repeated and effects the spring force and therefore the created friction is the means for using the weight in the sport machines. A monitor is attached to the sensors 20 and 21. Wherein sensor 20 is placed on the pulley 19-2 and sensor 21 is placed on the body 19-8.
During performing different movements pulley 19-2 also moves and as a result the sensor 20 attached to it moves in every cycle and therefore moves away from sensor 21 on the body. This back and forth movement creates a pulse.
The created pulse is sent to monitor 4 an after being processed by the electronic part. The monitor displays the information like the number of movements, work force, speed, and the time every movement lasts.
For adjusting force, the force change mechanism 2 is used. The user can adjust the force needed for every movement by utilizing the work force mechanism. To do this, the user turns the force change mechanism handle 2 which works like a one-sided clutch. The created force reaches to the pulley 2-5 and causes the cable attached to it roll on the other side of the pulley. The opposite side of the cable is attached to the external cover of the spring 19-3.The friction bond 51 is also placed on the cover. As a result the cable force is transferred to the cover 19-3.
Inside the cover is a spring 22 which is attached externally to the cover and internally to the internal shaft 19-1. This causes the spring 22 to recollect. A potential force created during this procedure is transferred to the shaft when the internal shaft 19-1 moves. This creates a resistance against the shaft movement.
On the other hand since the cover 19-3 is attached to the friction band 51 and the other side of this band is attached to the fixed body 8, the turning of cover 19-3 increases the friction between the band 51 and pulley band friction 19-7.
This in turn increases the friction force against internal shaft movement 19-1. During the performance of the machine, when the force is adjusted by the force changing mechanism, the resistance force against the user's muscles increases and as a result the force needed for any movement can be adjusted as needed.
FIG. 11 shows a special embodiment of the machine used for physiotherapy and rehabilitees centers. In order for the users to perform better, a special automatic chair is used by the user.
For medical use, the user can stand on this chair and for performing upper part body movements the user picks up handles 45 and starts his exercise. By pulling the handles the enacted force from the cable is sent to the part 42 and causes a tension in the spring inside cover 41.
In FIGS. 11-A to 11-C the internal and operating parts are shown. According to the fact that the cable attached to the handles 42 are also attached to internal spool 52 and this spool is also attached to the internal shaft 54, so pulling the handles by the user transfers the force to the internal spool 52 and this force is then transferred to the spiral spring through the shaft 54.
This causes recollection and force creation against user's muscles. To do lower part body movements the user sits on chair 40 and puts the feet in the foot place 38 and starts moving the feet.
The force generated by exercise 38 is transferred to the internal up prating parts 43 by the cable. The mechanism in this section looks exactly like mechanism 42 and the resistance of the spiral spring in this section is basically the performance of the machines.
The internal and operating parts of the system are inside the main frame with numbers 42 and 43.This machine provides its force from spiral springs because in physiotherapy and rehabilitation centers we don't need much work force.
It will be understood that, while presently preferred embodiments of the invention have been illustrated and described, the invention is not limited thereto, but may be otherwise variously embodied within the scope of the following claims. It will also be understood that the claims are not intended to be limited to the particular sequence in which the steps are listed therein, unless specifically stated therein or required by description set forth in the steps.
