Abstract

The principle of the presented invention is based on the fact that a constant weight (10) is continuously regulated for a variable gymnast load, which is transmitted to him through the small wheel (21) of the load transmission housing, by means of mechanical transmission through the system of fixed guiding wheels (3, 9) and also through moving of the movable wheel (7) of the cursor (6) in the regulation arm (5) by means of the manual rotatable wheel (13).

Description

VARIABLE RESISTANCE EXERCISE APPARATUS AND METHOD
BACKGROUND OF THE INVENTION
Field of the Invention The presented invention relates to the body-building equipment with continuous regulation of a gymnast load.
Description of the Related Art
Body-building equipment used so far regulates a gymnast load by means of the brick mechanism. Its principle is based on the fact that a weight in the form of bricks is loaded in guiding rails and a load for a gymnast is changed with change in the number of bricks.
The drawback of this method is that increase in a gymnast load is only secured by steps, not continuously, which is not suitable mainly with gradual efficiency loading of gymnasts of lightweight categories when adding one brick causes a substantial increase in a gymnast load. Another drawback is noisiness accompanying moving and marginal tripping of bricks.
The brick mechanism can not be used with the Hacken drep, Leg press and Multipress type equipment because a starting lift would come out from the marginal position. This means overcoming of a deadlock in starting phase of exercise which would be a great problem for a gymnast and without supplementary help would be practically impossible with heavier weights. This is the reason why the said equipment is not designed for the brick mechanism but use conventional increase in weight by means of discs.
Disadvantages of this method are both a slow process of loading and unloading weight and a need of large quantity of discs and a lot of storing room. It can also happen that due to carelessness when manipulating and removing discs accidents may occur - for example the Leg press equipment can be loaded with weights of up to 500 kg.
Designers recently try to overcome the marginal deadlock by means of auxiliary brick lifting, especially by using the electromagnetic field which is, however, material-demanding and uphill and, mainly, does not secure the continuity in regulation at a change in a gymnast load.
SUMMARY OF THE INVENTION The disadvantages mentioned above are radically solved by a method of gymnast load regulation with the body-building equipment according to the presented invention. It is based on the principle that a constant burden of a suspended weight is continuously regulated for a variable gymnast load by a mechanical transmission through a system of fixed guiding wheels and also by means of moving a wheel of a cursor of a regulation arm.
The principle of the equipment for executing this method is based on the fact that the front part of the regulation arm is rotably placed in a frame and its rear part is suspended at a load chain. This load chain passes through a system of load wheels fixed in the frame and leads up to a small transmission wheel of a load transmission housing to which is firmly connected.
The load transmission housing consists of the small transmission wheel fixed on a transmission axle which is rotably placed in the frame.
The interconnection of the equipment according to the presented invention with an exercise equipment is conveniently solved in the way that a prolonged end of the transmission axle with fixed large transmission wheel is placed in a carrier of the exercise equipment.
At the opposite side against fixing of the load chain the cursor with a movable wheel is slidingly placed along the lenght of the regulation arm. Through the said movable wheel a divided or undivided weight chain passes, with one end fixed to the frame. The weight chain also passes through a system of weight wheels fixed in the frame and is conveniently divided between the weight wheels once at least so that its dividing ends are fixed on the small and large rate wheels which are placed on the rate axle rotably embedded in the frame. The weight is suspended at the other end of the weight chain.
The main advantage of this method and the equiment according to the presented invention is a possibility to regulate a gymnast load in any position, independently on marginal points. Increase or decrease in weight can be done directly while exercising, without break in motion, which is important in body-building training when applicating ascensive or descending series where it is necessary to continuously increase or decrease a load in one series.
BRIEF DESCRIPTION OF THE DRAWINGS The presented invention is more closely clarified in the enclosed drawings, where Fig. 1 shows side elevation at the equipment with the divided weight chain and with two positions marked of the suspended load, regulation arm and small transmission wheel of the load transmission housing. Fig. 2 shows a simplified scheme of the mechanical principle of the method of gymnast load regulation with the body-building equipment and Fig. 3 shows the interconnection of the conventional exercise equipment with additional equipment according to the presented invention.
DESCRIPTION OF THE PREFERRED EMBODIMENT
The method of gymnast load regulation and the equipment for executing this method is exampled in an assembly (Fig.3) of the conventional exercise equipment of the Hacken drep type (left part of Fig.3) from which disc loads are removed. Thereto the equipment according to the presented invention is coordinated (right part of Fig.3). The interconnection is secured through the transmission axle 22 of the load transmission housing rotably placed in the frame 1 and carrier 11. An exercise load is fixed to the exercise chain 12 firmly connected to the large wheel 23 which is placed at the transmission axle 22 of the load transmission housing in the room of the exercise equipment. The small wheel 21 of the load transmission housing is already embedded on the transmission axle 22 in the room of the equipment itself according to the presented invention. One end of the load chain 4 which is led through the system of load wheels 3 attached to the frame 1 is firmly connected to the small wheel 21 (see Fig.1). The rear part of the regulation arm 5 is suspended at the other end of the said weight chain 4. The front part of the regulation arm 5 is rotably fixed in the frame 1 and also contains the manual rotable wheel 13. In the regulation arm 5 the cursor 6 with movable wheel 7 is slidingly suspended through which the divided weight chain 8 is led. One end of this chain 8 is fixed in the frame 1. The chain 2 is also led through the system of weight wheels 9 up to the other end at which a constant weight 10 is suspended in the form of loaded bricks. The weight chain 8 is divided on the rate wheels 91, 92 which are placed at the common rate axle 94 fixed in the frame 1. Two ends of the divided weight chain 8 are firmly connected to the small rate wheel 92 and large rate wheel 91.
A gymnast load is continuously regulated by means of rotating the manual rotable wheel 13 which moves the cursor 6 of the regulation arm 5 between two marginal positions (indicated in Fig.2). If the cursor 6 is as close as possible to the fulcrum of the regulation arm 5, this regulation arm 5 is in the position of the lowest possible load for gymnast. If the cursor 6 is moved as far as possible from the fulcrum of the regulation arm 3, a gymnast load rises more and more until it reaches the highest value when the cursor 6 is positioned at the trip.
A gymnast motion, showed by arrows in the bottom part of the terminated load chain 4 in Fig.2, causes slewing of the suspended end of the regulation arm 5 (indicated by arrows) and moving the suspended weight 10 in the up-down direction.
Industrial exploitation
The method of the continuous regulation of a gymnast load and the equipment for executing this method can be practically used with all types of exercise equipment used so far in Body-building Gyms and Fitness Centres when installed instead of the brick mechanism or disc method of loading.
