Abstract

An exercise machine incorporates a gas strut 1 to be actuated by a user. The resistance to effort needed to actuate the gas strut can be increased by operation of an adjustable piston/cylinder unit 2 so as to compress the gas within the gas strut 1. The adjustable piston/cylinder unit 2 is operated by applying a primary force F to the piston 4 compressing the gas 12 within the cylinder and within the gas strut. The primary force F may be applied either by using a threaded bolt arrangement (see figure 2), using a ratchet mechanism or by using a hydraulic system.

Description

1 2429412 Measurable Exercise Force system This invention relates to a
force system, in which the force resistance is infinitely variable, and having a measurable force resistance which increases to niaxhnuni reducing muscle impact strain and suitable for an exercise apparatus.
For many years exercise apparatus have used iron weights as a measurable force of resistance for exercising the body. This type of equipment relies on gravitational force as a resistance to movement and in many cases the apparatus has to be a strong cumbersome framework to withstand the weights involved. There have been apparatus using springs rubber bands and gas struts for resistance force but has not been measurable or infinitely variable.
The most popular has been the free weight system but when exercising with this type of resistance the body muscles have to take up the instant strain of the weight and can cause a muscle tear or impact strain.
With the present invention the exercise resistance is gradually built up to its maximum thus allowing the individual muscle being exercised to gradually warm up to take maximum strain. This feature of the exercise system has a great advantage over previous prior art in as much as it reduces muscle tear or muscular impact strain train.
The present invention has been devised to provide an alternative measurable resistance, which would replace the weights but give a measurable force and reduce muscular impact strain This devise allows the apparatus to be lighter smaller and more compact and portable than previous conventional machines.
Although gas struts have been commonly used for many purposes, there has not been a portable devise to vary the forces in the said struts and provide a measurable readout of the forces. This has been because the forces and pressures involved have been extremely critical but with modern it is now possible to overcome the problems involved.
Byway of example some particular embodiment of the invention will now be described with reference to accompanying drawing in which.
Fig I Shows a schematic sectional diagram of exercise force system showing gas strut I connected to force exchanger element 2 with a tube 3 and showing primary force element F. Fig 2 Shows in section the force exchanger element filled with gas 12 with a primary thrust system showing a mechanical means being a rotating force element.
Fig 3 Shows an exercise apparatus 15 with the use of the exercise force system replacing conventional free weight system at the rear of the apparatus.
Fig 4 Shows an exercise force system as a compact unit,having a hydraulic pump 23 and the force exchanger 2. .. enclosed in a hydraulic fluid container 24.
Fig 5 Shows an exercise apparatus in the configuration as a chair with a hydraulic primary force being used for the exercise force system, also the a mechanical primary thrust as Fig 2 can also be used and can replace the conventional free weight system The principle of the system is the introduction of a force exchanger transferring a measurable and variable force to the nitro gas used in the gas strut. By transferring a variable primary force to the gas pressure, and having a measured read out of that combined force, the total resistance of the system is measured.
The invention comprises a force exchanger 2 Fig I, being of a tubular section having a movable piston element 4, inside. The piston has a manual, mechanical or hydraulic primary thrust force F Fig I which pushes a piston 4 against a gas 12 Fig 1, The gas is compressed and is forced into a gas strut 1 Fig 1 at a given pressure according to the position of piston in the force exchanger 2 Fig 2 The movement of the piston determines the pressure in the gas strut and the said pressure is measured by a measuring element 5,and 6.
To use the exercise apparatus the handle 10 is rotated causing a primary force F to wind up the pressure in exchange element 2, to the force required and measured on pressure indicator 5, and 6. The force in the exchange element is transferred to the gas strut 1, which acts as the force resistance for the exercise elements.
The primary force F Fig 1 can be one of the following systems.
(A) Mechanical means by which the piston element 4 is moved by a threaded element 9 Fig 2 rotated by a rotating element 10. A disc element I I Fig 2 has a threaded hole where the rotating element 9 passes though. Attached to the element 11 is a tube element no 8 Fig 2 so as the rotating element 9 rotates it pushes the piston element no 4 compressing the gas 12. .As the piston 4 moves forward the gas 12 is pushed into the gas strut I increasing the pressure and thus increasing the resistance force for the exerciser. As the rotating element 9 is rotated in the opposite direction the piston element 4 moves back thus reducing the pressure in the strut I and reduces the exercise force for the exerciser, thus a infmitely variable and measurable exercise system is achieved.
(B) Mechanical means by which the piston 4 is moved by a rod element being moved by a ratchet element forcing the gas into the gas strut at a variable and measurable pressure giving a variable and measurable exercise force for the exerciser.
(C) A hydraulic means by which the piston 4 is moved by a hydraulic element forcing the gas into the gas strut at a variable and measurable pressure giving a variable and measurable exercise force for the exerciser.
The hydraulic element fig 4 comprises a gas strut 1 connected to a base element 26. A force exchanger 2 enclosed in a fluid container element also connected to the base element and a hydraulic pump having a handle element 25. The fluid is pumped into the force exchanger element 2 by pump element 23 which compresses the gas 12 increasing the pressure in gas strut 1 to a given force required for the exerciser The hydraulic element is shown in fig 5 under the seat of the exercise apparatus, but can be placed in any position suitable for its use.
A quick release element on any one of the thrust force elements can be used to bring the force in the gas strut I Fig 1 to zero. The exercise apparatus has the exercise force system at the rear, and a cable 20 connected to the front leg extension exercise. Cable 20 then passes under lower pulleys and up to the pulley 13, down to pulley 2l,and connected to floating pulley 22. Arm press exercise cable 21, is connected to handles 19 Fig 3 under floating pulley 22 and to ann press exercise on opposite side. When the arm press elements are used the cable 20, pulls down gas strut 1, via the floating pulley 22, giving the exerciser the force resistance for the exercise.
When the leg extension element 17 is connected to cable 20, it pulls down the gas strut I via pulley 13, giving the exerciser the force resistance needed for the exercise The leg extension element is also used for the arm curl exercise by lifting elements 17 which can have an extension cable to the required height. For the high pull exercise element 16 is pulled up via cable 23, attached to floating pulley 22, and compresses strut 1, giving the exercise force required for the exerciser.
