Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus suitable both for use as a means of transportation and for use as an exercise machine.

Known means of transportation, such as bicycles, require the rider to exercise certain muscles of the body. However, on a bicycle, only the leg muscles and, to a lesser extent, the abdominal muscles are primarily worked.

It has recently been reported in institutions that some medical practitioners are of the opinion that the most comprehensive exercise can be done when participating in competitive rowing. The rower sits on the slide,
The slide seats can be moved toward and away from the position where the rower's feet are fixed. That is, when rowing, both legs and arms are moved, and therefore virtually all parts of the body are moved. However, rowing requires a large area of open water.

SUMMARY OF THE INVENTION An object of the present invention is to provide an apparatus that can be used as a vehicle while also realizing healthy exercise for the human body.

According to the invention, the gymnastic equipment comprises wheels, at least one of which is configured to be practically driven.
a vehicle having a chassis, a rider seat installed on the vehicle, at least one drive member also on the vehicle capable of linearly reciprocating movement, and directing the linear movement of the drive member to driven wheels; , and a link that converts and transmits this linear motion into rotational motion of the driven wheels.

In a preferred form of the invention, the instrument is in the form of a tricycle having a front wheel and a pair of rear wheels capable of steering the vehicle. However, it will be appreciated that other configurations are possible.

In a first alternative, the vehicle may be four-wheeled and may include a pair of front steering wheels and a pair of rear wheels. In a second alternative, the vehicle may be in the form of a tricycle, but with a pair of steering wheel fronts and a single rear wheel.

Preferably, both rear wheels are configured to be practically driven. However, it is also possible that only one rear wheel is actually driven, as is the case in the second variant described above.

As part of its structure, the chassis may include tubular upper and lower hollow rails with rectangular cross-sections.

These rails define a housing for movable members connected to an endless chain suspended around two spaced apart sprockets, each of which moves in the longitudinal direction of its associated rail. It is possible and
In this case, means are provided for transmitting the linear movement of these members to one or more wheels of the vehicle via a transmission gear having a suitable transmission ratio, converting the linear movement into a rotational movement.

Preferably, the movable member disposed within the upper rail includes a handle configured for manual operation, and the member associated with the lower rail preferably includes two movable handles configured to be moved by the rider's legs. The upper rail, including the pedals, may be tiltable about its longitudinal axis, with gear means being provided to transmit such tilting to the steerable wheels of the vehicle. Although this transmission transmits the motion of the upper rail to the steering wheels, it is within the scope of the present invention to use other conventional means. This is especially true for 2
In the case of embodiments involving a single front steering axle, in this case means different from the endless chain described above may be used.

Presently preferred embodiments of the invention will be described in detail below, with reference only to the accompanying drawings, in which: FIG.

With reference to the figure, the novel gymnastic equipment comprises a chassis 1 comprising upper and lower rails, designated 12 and 14, respectively.
Includes vehicles with 0. Upper rail 12 is supported on front and rear upright members designated 16 and 18, respectively. A portion 20 of the lower rail 14 extends rearward.

Both rails 12 and 14 are also centrally arranged and located in the plane of the longitudinal axis of the vehicle when viewed in plan.

An axle 22 is provided near the rear end of the rail 14, and a wheel 24 is mounted at each end of the axle 22.

An upright rear support member 18 of the rail 12 is secured to and extends upwardly from a rearwardly extending portion 20 of the rail 14.

The upright members 18 are reinforced by diagonally arranged trusses 26. The members 81, 82, and 26 are provided as reinforcing members of the chassis structure. A hawk 228 is provided at the front end of the vehicle, into which the steerable wheels 30 are secured.

An adjustable seat 32 is provided for the rider.

The seat can be adjusted in the longitudinal direction of the vehicle to allow use by people of different sizes.

As shown in particular in FIG. 2, the upper portion of the hoe 228 is provided with a sleeve 34 within the sleeve.

A lock 36 to which a bevel gear 38 is attached is arranged. Gear 38 cooperates with crown gear 40.

An axle 42 is fixed at one end to the crown gear 40, and the axle 42 rotatably passes through a member 44. Part 4
The end remote from the 40-crown gear 40 is fixed to the chassis 10 via members 81 and 16.

The upper rail 12 is fixed at its front end to an axle 42 and carries at its rear end a short shaft 19, which is rotatable in an aperture provided at the upper end of the upright member 1B. .

The upper rail has a tubular shape with a rectangular cross section. Elongate slots 48 are formed in the generally vertically disposed sides of the rail 12.

A diagonal arm 50 extends from member 44 and
An idle sprocket 52 is installed at the upper end of the wheel. A similar arm 54 extends from upright member 18 and
4 holds a driven sprocket 56 at its upper end. An endless chain 58 is wrapped around the two sprockets 52 and 56. That is, the sprocket and chain are housed within the hollow rail 12.

A reciprocably movable pulley member 60 is connected by bearings to the upper feed of the chain 58 , and a pulley 60 is connected to the stopper wheel 2 which guides this pulley during its travel within the rail 12 .
Contains 6. Laterally extending handle pars 62 are provided on each side of the pulley 60.

Another sprocket 64 is fastened to the same axle as sprocket 56. Another chain 66 is wrapped around sprocket 64 and sprocket 68. After passing through transmission gear 70 and relatively large sprocket 84 , power is transmitted by chain 72 to wheel 24 via differential 83 .

Similarly, power to the wheels 24 can be supplemented by the rider's legs. For this purpose, a pair of pedals 74 are provided which operate similarly to the handlebars/9-62.

When one or both pedals 74 are pushed forward by the rider's feet, an endless chain is fed around the idler sprocket 78 and driven sprocket 80. A body 82, equivalent to the pulley 60, is fixed to the chain 76, and this pulley also has suitable wheels (not shown) during its travel within the housing provided by the rails 14.
You will also be guided by Driven sprocket 80 cooperates with sprocket 84 via transmission gear 70, through which power is transmitted to wheel 24.

In operation, a rider, generally designated by the letter R in FIG.

In the starting position indicated by R1, the first rider leans forward with both arms fully extended, and both legs are bent and the knees are drawn toward the chest. Now the rider is handlebar par 62
and at the same time straighten both legs, at the end of the stroke taking the position shown by R2 in Figure 1.

This moves the reciprocating member 60 rearward with respect to the upper rail 12, and this movement is caused by the chain 58.
transmitted by. The movement of chain 58 rotates sprockets 52 and 56, which in turn rotates sprocket 64, causing movement of chain 66, and power is transferred to sprocket 68 and transmission gear 7.
0, and a relatively large sprocket 84, and is transmitted to the wheels 24 via a chain 72° and a differential mechanism 83 fastened to the shaft 22, and a sprocket. This last-mentioned sprocket could have a stepwise increasing diameter, and different transmission ratios could be provided by such diameter with appropriate shifting mechanisms. A similar arrangement could be provided for the lower rail 14. has been done. The pedals 74 may be operated simultaneously with the nodal per 62, or alternatively the handle and pedals may be operated alternately or separately. The rider's feet are held in stirrups (not shown) which are fixed to the pedals such that the portion of the stirrup facing the pedal operating surface is moved to the position at which the pedal 74 begins its stroke. May be able to be pulled back. A semi-circular stirrup 86 is proposed herein, one side of which is open so that the foot can be moved laterally off the pedal, Lua 4, in order to operate the brake, which will be detailed below. .

Movement of chains 58 and hips 6 in rails 12 and 14 in one direction of motion transmits power to wheels 24, and movement of the chains in the opposite direction causes sprockets 56 and 80 to freely rotate, resulting in The handlebar 62 and pedals 74 return relatively easily to their starting stroke positions. This configuration also allows the vehicle to be driven by one motion chain independently of the other chain.

In order to steer the vehicle, the rail 12 is rotatably tilted about its own longitudinal axis, represented by the collinear axle 42 and the short axis 19. Additionally, tilting of the rail 12 is accomplished by applying the necessary force to the handles/62 to change the angular orientation of the rail 12. A crown gear 40 imparts rotational movement to the bevel gear 38 and thus to the steerable wheels 30 via the shaft 36 .

It is clear that by using the vehicle according to the invention, the muscles of virtually every part of the body can be worked, and at the same time the user of the vehicle can also move from one location to another. Will.

With particular reference to FIG. 5, the braking mechanism includes an endless chain 87 that rests on two idler sprockets 85 and 86. The chain is attached to two arms 88 extending from a shaft 89.

A pedal 9° fixedly mounted on a shaft 89 rotates when stepped on by the rider's foot, causing rotation of the shaft 89, which rotation causes movement of the arm 88 and thus traction of the chain 87. cause The chain pulls the sprockets (85, 86) in the direction indicated by the arrow. The sprockets 85, 86 can move within the slots 92, and the movement of these sprockets is transmitted via steel wires 91 to conventional brakes, ie disc brakes or brakes such as those used on bicycles. When the pedal 90 is released, the sprockets 8!5, 86 are returned to their original positions by the spring.

This brake mechanism can also be operated manually, the pedal being replaced by a lever or handle which transmits the hand movements to the brake via the same steel wire.

Although the invention has been described and illustrated with respect to presently preferred embodiments, it will be apparent to those skilled in the art that many modifications and variations are possible without departing from the scope of the claims. .

Accordingly, the movement of handle 7-62 and pedal 740 back to the position at the beginning of the stroke may be assisted by the spring.

As already mentioned above, the vehicle can be configured in various ways.

In the case of a two-wheeled vehicle, the vehicle has one steering front wheel and one driving rear wheel, with drive dependent on the rider's ability to maintain balance. In both the three-wheeled and four-wheeled versions, which have two front steering wheels, the front steering mechanism is virtually the same as that used in automobiles. In this case, the manually induced tilting motion transmitted through member 12 could be transmitted by a different mechanism than that described here.
