Abstract

A pedalling simulating implement, with adjusting means for adjusting the variable effort depending on the inclination, comprises an adjustable braking system coupled to a bearing construction including a seating plane and a handlebar.

To the bearing construction is pivoted a pulley to which is rigidly connected a pair of pedals, the pulley being kinematically coupled to a flywheel.

This implement is characterized in that it further comprises swinging means adapted to allow the bearing construction to swing with respect to the base of the implement, so as to change the inclination of the implement depending on the pedalling effort applied by the athlete for pedalling.

Description

BACKGROUND OF THE INVENTION

The present invention relates to a pedalling simulating implement, including adjusting means for adjusting the pedalling effort depending on the inclination.

As is known, the most part of prior pedalling simulating implements conventionally comprise braking systems, either manually or electromechanically adjusted, designed for simulating the pedalling resistance encountered on positive inclination or uphill grounds.

The above mentioned braking systems comprise, for example, friction braking, magnetic and electromagnetic braking systems, operating based on friction, magnetic and electromagnetic forces.

Further prior pedalling simulating devices are designed for swinging along a cross and longitudinal axis to simulate a road pedalling condition.

SUMMARY OF THE INVENTION

The aim of the present invention is to provide such a pedalling simulating implement which is adapted to simulate a pedalling operation on slanted roads.

Within the scope of the above mentioned aim, a main object of the invention is to provide such a pedalling simulating device or implement, for providing a pedalling feeling much more realistic than that provided by existing like implements.

Another object of the invention is to provide such an implement which is very flexible in operation and can be made by already existing methods and systems.

According to one aspect of the present invention, the above mentioned aim and objects, as well as yet other objects, which will become more apparent hereinafter, are achieved by a pedalling simulating implement including adjusting means for adjusting the pedalling effort depending on the inclination, said implement comprising an adjustable braking system coupled to a bearing structure including a seating plane and a handlebar.

To said bearing structure is pivoted a pulley to which is rigidly fixed a pair of pedals, said pulley being moreover kinematically coupled to a flywheel.

This implement is characterized in that it further comprises swinging moans designed for allowing the bearing structure to swing with respect to a base of the implement, thereby an inclination of the implement will change the effort applied by the athlete for driving the pedals.

BRIEF DESCRIPTION OF THE DRAWINGS

Further characteristics and advantages of the present invention will become more apparent hereinafter from the following detailed disclosure of a preferred, though not exclusive, embodiment of the invention, which is illustrated by way of an indicative, but not limitative, example in the accompanying drawings, where: [0011]
FIG. 1 is a side elevation view of a pedalling simulating implement or device; [0012]
FIG. 2 is a further side elevation view of a pedalling simulating implement, according to a first aspect of the present invention; and [0013]
FIG. 3 is a further side elevation view of a pedalling simulating implement or device according to a further aspect of the invention.[0014]

DETAILED DESCRIPTION OF THE INVENTION

With reference to the number references of the above mentioned figures, FIG. 1 shows a typical pedalling simulating implement or device, including a magnetic braking system which can be manually adjusted, and comprising a bearing or supporting [0015] framework 1 including a seating plane 2 and a handlebar 3.
To this same structure a pivoting [0016] pulley 4, to which pair of pedals 5 are rigidly coupled.
Said [0017] pulley 4 is coupled, through a transmission or driving belt 6, to a flywheel 7.
The braking system position, as shown by an [0018] arch 8 having inner magnets 9 pivoted to the structure 1′ at the point M, with respect to the flywheel 7, is adjusted by an adjusting device 10 through a cable 12.
In the above braking system, the approaching and moving away displacements of the magnets with respect to the outer rim of the flywheel, which is generally made of a ferrous material, and sometimes coated by copper or aluminium, cause the braking load to increase or decrease. [0019]
FIG. 2 illustrates, merely by an example, a first embodiment of the present invention, applied to the implement shown in FIG. 1. [0020]
In this embodiment, the bearing supporting [0021] structure 20 is adapted to swing about the implement base 21, on a pivot pin 22, and the inclination of the structure 20 may be adjusted by extending a piston 23, being controlled by a control unit 24.
The [0022] braking system 8, 9, for example of the same type as the above disclosed braking system, is coupled to the implement base 21 by a support element 25.
The approaching and moving away displacements to/from said [0023] flywheel 7 of said braking system, and accordingly the increase or decrease of the braking load, is in this embodiment controlled by inclining the structure 1.
As in the above disclosed example, this embodiment of the invention can be applied to any pedalling simulating implements, including any desired braking systems, by merely providing different adjusting means for adjusting the inclination of the implement. [0024]
In FIG. 3, for example, the braking system, shown by the [0025] arch element 8 supporting magnets 9, is coupled to the swinging construction 30. instead of being coupled to the base 21, through a supporting element 31, said arch element being moreover urged by a spring 32, and coupled to the implement base 21 through a tie-rod 33.
Even in this embodiment, the position of said arch or curved element, with respect to the [0026] flywheel 7, will be determined by the inclination of the structure 1 to the implement base 21.
It has been found that the invention fully achieves the intended aim and objects. [0027]
In fact, the invention provides a pedalling simulating implement which has been specifically designed for simulating, for an implement user, a pedalling on slanted or inclined tracks, while providing a pedalling feeling much more realistic than that provided by prior like devices. [0028]
In fact, the pedalling simulating implement according to the present invention changes the inclination thereof depending on the pedalling effort applied by the athlete or user. [0029]
In particular, the implement according to the present invention changes the frontward—rearward inclination by changing the braking load. [0030]
In particular, by frontward inclining the implement (that is in the handlebar direction), the braking load decreases, thereby providing the athlete with a downhill pedalling feeling. [0031]
On the contrary by rearward inclining the implement, the braking load will increase, thereby simulating an uphill pedalling condition. [0032]
Actually, the inclination of a bike, and the pedalling resistance thereof, would greatly change as the bike running plane is inclined, in particular in pedalling on roads and the like. [0033]
Thus, the invention provides a much more realistic pedalling feeling than that of prior like devices. [0034]
While the inventive concept specifically relates to changing the inclination of the implement depending on the braking load, this concept can be applied by any desired methods and to any desired braking systems and related adjustment means. [0035]
A great advantage of the invention is that it can be applied to any pedalling simulating devices, and any desired braking systems, by providing different adjusting means for adjusting the inclination of the implement. [0036]
In practicing the invention, the used materials, as well as the contingent size and shapes of the component elements thereof, can be any, depending on the requirements and status of the art. [0037]
