Description

Body-building device

Technical field

The present invention relates to a kind of compactly designed drag devices that has, this device is used for multiple use, for example stored energy mechanism or pedal, Exercycle, oval machine or based on the fitness machine of the system of flywheel, wherein as required, hand that body exercising machine can be by the user and arm or leg drive.

Summary of the invention

The invention provides a kind of drag devices, it comprises and is mounted to the opposing loading component that rotates around first axle, is mounted to the drive member of rotating around first axle, is used at least one actuator of rotating drive member and is used for rotating drive is transmitted configuration from the driving that the drive member transmission becomes the rotating drive of opposing loading component, and wherein resists the velocity of rotation of the velocity of rotation of loading component greater than drive member.

First actuator can be taked any suitable form, but the form of crank preferably.

Preferably drag devices comprises second actuator, and first and second actuators are positioned on the opposite side of opposing loading component separately.At each actuator is under the situation of crank, and the best angled ground of crank is arranged on 180 ° mutually.

The opposing loading component can be installed on the axle, and can freely rotate around this.In other words, the opposing loading component does not need to be fixed on the axle.Each actuator can directly be fixed on the axle.

Drive member can be installed on the axle, and can be fixed on the axle.

Driving and transmit configuration can be any suitable type, and preferably includes the bar that is parallel to first axle; Drive and be installed in first pulley on the bar in first side of opposing loading component from drive member by band, chain or similar device, first pulley has the diameter less than the drive member diameter; Be positioned at the opposing loading component away from second pulley on second side of first side, second pulley is fixed on the bar; Be fixed on the opposing loading component and be positioned at the 3rd pulley on second side of opposing loading component, the 3rd pulley has the diameter less than second pulley, and is rotating with the opposing loading component on first direction at least around first axle; And be used for from band, chain or the similar device of second pulley drive the 3rd pulley.

The 3rd pulley can be fixed on via the unidirectional drive device of for example one-way clutch or bearing on the opposing loading component, makes that the rotating drive on the first direction is delivered on the opposing loading component from pulley.But the action of unidirectional drive device makes this driving not be delivered on the 3rd pulley from the opposing loading component.

" pulley " is active or the slave unit that uses and comprise pulley, cam, roller or similarly rotation here with general sense.

The opposing loading component can be any suitable type, and the form of flywheel preferably.Flywheel can be braked in any appropriate manner, so that the power that produces the opposing load is provided, this power is used for resisting freely rotating of flywheel.In this regard, can use band or similar rubbing device, this device is used for resisting the motion of flywheel, magnetic brake or any device that is equal to.The present invention is not limited to this.

Description of drawings

With reference to the accompanying drawings, further describe the present invention by example, in the accompanying drawing:

Fig. 1 represents drag devices according to a kind of form of the present invention with decomposed form.

The specific embodiment

Accompanying drawing is represented according to drag devices 10 of the present invention with decomposed form.Only understand that wherein the present invention operates those required parts.Will appreciate that for simple and clear purpose and omitted for example other parts of housing, safety shield or analog.

Device 10 comprises the axle 12 that is positioned on the first axle 14.With flywheel 16 is that the load-resisting device of form is mounted on axle and freely rotates.Therefore, flywheel does not rotate together with axle, but rotates around axle.

On first side 18, axle 12 has a plurality of plane surfaces 20.With the pulley with fin be the drive member 12 of form be installed in axle on the end of stretching out on first side, and fix on it, make pulley and axle rotate together.

Have with the crank actuator 24 in the hole 26 of the shaft end complementation that has plane surface 20 and engage with plane surface in the mode that can not unclamp.Actuator comprises the bar 28 that ends at around the handle 30 of minor axis 32 rotations.

Scaffold member 34 is used for the external part of bolster, and actuator 24 and drive member 22 are separated.

Be positioned at parallel to the axis 14 and second axis 41 that is spaced from bar 40 at one end be installed on the unshowned bearing, bearing engages with scaffold member 34.First pulley 42 is fixed on the bar, and itself and bar are rotated together.Pulley has the diameter less than drive member 22.Pass regulating wheel 48 have a fin be with 46 to be used for rotational motion is delivered to first pulley 42 from drive member 22.

Its diameter is installed on the end of bar 40 on second side 62 of flywheel 16 greater than second pulley 60 of first pulley 42.What have fin is with 64 to engage with second pulley, and is used for rotational motion is delivered to the 3rd pulley that is fixed on the flywheel from second pulley.The diameter of the 3rd pulley 70 and second pulley are similar.Axle 12 stretches out from flywheel and the 3rd pulley 70 in second side 62.Axle described stretch out on end and flywheel first side the external part category seemingly, and be loaded with the flat structure 20A that is similar to plane surface 20.Crank actuator 80 can engage with flat structure 20A.

In this example, actuator 80 on angle with respect to 180 ° of actuator 24 deflections.But actuator is correlated with, and actuator is when first direction rotates around axis 14, and another actuator rotates with identical speed in the same direction.

In the example shown, device 10 is designed to activate by hand.Use technology well known in the art, band or similar device that flywheel 16 can use the periphery with flywheel to be frictionally engaged come friction catch.But preferably, the magnetic brake of type known in this field is used for preventing as required freely rotating of flywheel.Magnetic brake generally includes one or more magnets 90, and magnet is fixed on the flywheel, and rotates together by ferromagnetic parts with flywheel, wherein produces the electromagnetic field that the restriction flywheel rotates.Such brake is regulated easily, so that either large or small brake force is applied on the flywheel.

If come turning cylinder 12 by operating one or two actuator 24 and 80, drive member 22 is rotated in the same direction so.Rotating drive then is delivered on the bar 40.When the diameter of drive member 22 during greater than first pulley, the velocity of rotation of first pulley is greater than the velocity of rotation of member 22.Second pulley has the diameter greater than first pulley, though and therefore it moves under the velocity of rotation identical with first pulley, and its peripheral speed is bigger.This means that the 3rd pulley that has less than the diameter of second pulley rotates under the velocity of rotation that increases.As mentioned above, the 3rd pulley is fixed on the flywheel, and therefore flywheel rotates under the speed that significantly increases with respect to the velocity of rotation of actuator 24 and 80.

Described structure has compact characteristic, and when taking actuator, highly effective in the process of the opposing load movement that flywheel is provided.

In this example, each handle 30 is designed to use by hand, but by suitably being shaped, also easily as pedal, makes that this device can be the operation of hand or pin as required.

This drag devices can be combined on the body exercising machine of for example pedal, oval training aids, bicycle, Boating type machine and analog in a variety of forms.Equally, drag devices can be used as stored energy mechanism, and wherein rotational energy mainly is stored in the flywheel.

One-way clutch or bearing 84 can be used between flywheel 16 and the 3rd pulley 70, make rotating drive only be delivered on the flywheel from pulley on the first direction.But rotational motion will not be delivered on the pulley from flywheel.
