The invention relates to sports training machines, in particular, exercise machines intended for the development and strengthening of human body muscles. It will have the most widespread use for the training involving cyclic hand movements (running hands), and for muscle-strengthening exercises both of cyclic nature and repetitive nature, such as presses, arm bending and unbending exercises, dip bar exercises etc.
The life of a modern man is closely related to the use of exercise machines. They are helpful in achieving an excellent physical shape, preserving a great health condition for a long time, restoring disordered functions during the rehabilitation. Nowadays regular gym visits are not required as it is possible to achieve desired results by installing necessary sports exercise machines at home. The advantage of home exercise machines is the possibility to build muscles at any time without sticking to any gym operation hours that are not always coincident with a real free time a person may have. Constant gym membership purchases can affect a family budget in a considerable way. Besides, as a rule, only family members have access to home exercise machines.
Exercise machines are widely popular not only among the users who would like to have athletic body shape and develop different types of muscles but also among those who want to regain their health after injuries, various diseases etc. It is because of high popularity and real benefit of exercises the particular attention is given to the issue of creating new and improving existing structures of training and rehabilitation exercise machines.
The prior art represents a wide range of structural embodiments of various exercise equipment where the features of construction of each embodiment primarily depends on what group of muscles should be built, as well as the location of the exercise machine.
Thus, the RF patent No. 12793 (IPC8: A63B 9/00, published 10 Feb. 2000, Bulletin No. 4) represents one of the most classic types of exercise machines— «gym ladder—monkey bar», whose key purpose is arm building. The exercise machine is made in the form of a mounted vertical frame with bars consisting of two equal movable parts. The upper frame is additionally equipped with a rope ladder. During the training the user is doing “running hands”, alternately grabbing the bar and moving along the ladder.
The disadvantage of this exercise machine is a low efficiency level and limited range of use. The reason for this is that during the bar arm grip the user's body hangs loose, with the joints being strained by its personal weight. Under such conditions a person can get tired very quickly especially when he/she is overweight or physically disabled. Due to simplified design of this machine, only a certain group of muscles can be trained, so, it is obvious that it can be interesting and high in demand for the persons doing some physical workout but not going in for sports.
The machine is known for swimmers' muscle-strengthening exercises with the key purpose to train arm muscles during rowing movements. The exercise machine is a supporting plate with the built-in hook attached to the wall bar. It consists of flexible rod tossed over the roller, where the handle gripped by a sportsman is fixed on one end, and the other end is connected to the resistor element made in the form of a slide bar (A.s. No. 204212, IPC7:A63B, class 77a, 21/00, published on 9 Oct. 1967, Bulletin No. 21, 1967). The training provides for the resistor element load change allowing the manipulation of the value of force that can be developed by a sportsman.
As in the example above, the disadvantage of training on the exercise machine is a limited list of muscles to be trained—in the process, the upper body is involved, while the lower one, in particular, muscle groups of the press, is only partially strained. The training process itself cannot be categorized as flexible, because practically the same exercises are performed on this exercise machine bringing the same result. Besides, the exercise machine cannot be moved from place to place—it is tied to the gym wall, and it is not suitable for use at home at all.
The exercise machine which is more promising in terms of enhancement of operational capabilities is the exercise machine presented in the patent of the Russian Federation No. 2635795 (IPC9: A63B 21/00, published on 15 Nov. 2017, Bulletin No. 32). In contrast to the exercise machines described above, it is mobile (installed on wheels), so, if necessary, it can be moved to any convenient place depending on the configuration of the room, in addition, the gymnastic equipment of the exercise machine provides the opportunity to train different muscle groups. The exercise machine is built on the basis of a controlled pneumatic cylinder with the rod tied to the power cable, tossed over a roller, mounted on a vertical telescopic prop. The loose end of the cable is equipped with quick-release fasteners for various areas of the user's body.
The point of training exercises is that depending on the specifics of the task, certain areas of the user's body are tied to the power cable using fasteners, thereafter the user starts making training movements. The telescopic prop allows changing angles of traction force depending on the group of muscles the training is focused on. The displacement amplitude of body areas, programmed efforts, time parameters of the exercises are transmitted to the rod of pneumatic cylinder whose operation mode is adjusted through computer software via control panel.
The main disadvantage of this exercise machine is the complexity of structural design, considerable bulkiness and high cost—it is equipped with complex structural elements, besides, it requires computer hardware. It is obvious that this exercise machine is not accessible to a broad spectrum of users.
The hand grip exercise machine is taken as a prototype of the invention having two L-shaped props and interlinked load elements (RF patent No. 172210, IPC9:A63B21/22, published on 30 Jun. 2017, Bulletin No. 19). The load elements are two wheels fixed on the same axis, made in the form of a rim with levers (spokes). The wheels are interconnected by bars and L-shaped props are tied by horizontal tubes making the props stable.
During the training with the exercise machine, the user in suspension climbs on the bars by performing “running hands”. At this moment the wheels turn with the efforts adjusted by the braking device.
The disadvantage of the exercise machine is its simplified and rather primitive construction focusing on a limited range of movements only and therefore unable to ensure the training of a broad group of the muscular system. For example, the user cannot develop grip strength and endurance, hand and forearm strength effectively, let alone a lower part of the body and crunches. Besides, the structural components of the exercise machine and the properties of their attachment are very unreliable and are not designed for significant efforts, thus, it is more acceptable for children.
As stated above, during the “running hands” exercise, the joints are strained by a personal weight and that results in high tiredness and for some categories of people such type of training is very problematic or even impossible.
The disadvantage of the exercise machine also lies in the fact that it is not mobile, the exercise machine is fixed to the wall through two pairs of hooks.
This invention is based on the creation of a multifunctional, structurally simplified hand grip exercise machine, which is easy to install and operate by improving its structural construction, in particular, by equipping it with wheels, fitting it with levers on both ends of the shaft, pairwise coupled bars tossed over the transverse arms, allowing the user to make intense movements and to develop considerable traction force in the conditions of variation of the resistance value, diversify grips, body positions and postures relative to the exercise machine and thereby create the load for a broad group of muscles of both upper and lower body.
This task can be achieved thanks to the fact that in the hand grip exercise machine having two L-shaped props and interlinked load elements, according to the invention, L-shaped props are mounted on the supporting frame on the wheels, strengthened by stiffening ribs and have openings through which a shaft extends on two sides with at least four levers installed circle-wise oriented at the same angle to each other and strengthened by at least one row of jumpers, while the levers installed on both sides of the shaft are connected pairwise by transverse handles, through which the endless rope can be thrown, besides, the L-shaped props are equipped with lanyards tied to straps tossed over the ends of the shaft. The weights having different range of loading force can be fastened on the transverse handles of the exercise machine.
The technical result that can be achieved during the performance of the proposed exercise machine is contingent on the features distinguishing it from similar designs of training devices described according to the prior art, in particular, in the solutions taken as a prototype.
The main distinguishing feature of the proposed exercise machine is its versatility, because the structure of this device combines the capabilities of a whole range of training means of various types, each designed for training only a specific group of muscles. First and foremost, this versatility is contingent on a wide range of possibilities provided by the unlimited number of levers and transverse handles (crossbars) between them, as well as the rope tossed over these handles allowing to train even those groups of muscles that cannot be loaded on standard exercise machines.
Thus, when making pulling movements under conditions of different lever rotation resistance value, the exercise machine allows the maximization of the force of grip, hand and forearm. Its structure allows the change of body position relative to the exercise machine adding a variety of exercises both through levers and through the rope involving a great array of muscles of both upper and lower body into the training.
It is well known that ordinary sit-ups often can create unnecessary strains on the neck and back making them extremely complicated or even hazardous. Holding onto the rope, levers or transverse handles, one can choose a position (for example lying position) where the sit-up can be efficiently done without involving neck and back muscles. Likewise, the leg muscles can be easily trained in a lying (or sitting) position.
Thanks to the chain, the exercise machine can be connected to any cable-pull machine with removable weights (kettlebells) and thus provide a possibility to train the arm and shoulder muscles by pulling the rope of the cable-pull machine up, as in a deadlift, or down, as during the rope rising.
The “dip bar exercise” simulation is a variant of training exercises. To do such exercise, a sports rubber (rubber tape) is fixed to the supporting frame and when it is stretched, a certain group of muscles can be strained.
By reducing the resistance and finding the optimum speed, the exercise machine can be used for aerobic training, and thanks to the variety of exercises and resistance control, it will be an aerobic exercise with an incredible amount of calories burned. At the same it provides cardiovascular and power load which cannot be reached during the trainings using standard sports equipment.
It should be noted that the rope is a very important and effective supplement to the proposed design of the exercise machine, it significantly increases its operational capabilities, but the training through the use of such machine cannot be so effective without a rope. For example, strength and endurance can be developed by running over the bar and exercising “running hands”, with the important moment of training being the possibility to change the power of resistance of levers' rotation. For this purpose, the weighting mediums of different weight are fixed on transverse arms of the exercise machine, and the resistance is adjusted by the braking system—lanyards connected to belts tossed over the ends of the shaft.
Summarizing the material, we can note that the proposed exercise machine is an effective tool for increasing strength and endurance, which is a great supplement to daily training for both professional athletes and amateurs, people of all ages and different physical condition. Thanks to its mobility, it can be equally successfully used in gyms, at home and for outdoor sports grounds.
The structure of the proposed hand grip exercise machine is explained on drawings illustrating the following:
The hand grip exercise machine (
The exercise machine is operated as follows:
The structure is installed in the place required for exercises. With the help of a lanyard, the power of resistance of the shaft is determined for a specific situation—the more efforts the exercise requires, the more the shaft is clamped. Then, by exerting some efforts, the user performs training to roll the shaft. These efforts can be exerted by rope or by any other method described above, in particular through the use of weights or sports rubber.
