Abstract

The pedal (11) has 3 freedoms of movement with respect to its crank (10) by means of a connection comprising a rotatable shaft (13) received in a sleeve (14) and a post (17) attached to the shaft by a ball and socket joint (19). The freedoms of movement allows a user of such apparatus to simulate jogging or running. <IMAGE>

Description

SPECIFICATION Improvement in pedal-type exercisers This invention relates to exercisers, and more particularly, to pedal-type exercisers.
Exercising by jogging or riding a bicycle is very popular. For those who do not want to do their exercising out of doors stationary bicycle-type exercisers are provided which can be used in the office, at home, or in an exercise salon or gymnasium.
It is thought by some that riding a bicycle or using a stationary exerciser bicycle simulates running or jogging. Of course, although healthful, that is not so because pedaling a bicycle really does not simulate running or jogging. This is for the reason that-running or jogging has a different gait than pedalling, and in fact uses many more parts and muscles of the body.
It is an object of this invention to provide a pedal-type exerciser which will enable the user thereof to more nearly obtain the exercise obtainable by running or jogging.
I have discovered that conventional pedal-type exercisers are deficient because they allow the pedal freedom of movement in only a single sense or direction. In my invention I provide a pedaltype exerciser in which the pedal has additional modes of movement so that the user thereof can more nearly simulate the gait of running or jogging.
The invention will be best understood by considering the following description and single sheet of drawings showing one form of my invention.
Referring particularly to the drawings, shown therein is a broken away perspective view of an exerciser pedal assembly comprising a crank arm 10, a flat foot pedal 11, and a stirrup 12 for the pedal. Pedal 11 is mounted on a shaft 13 which is free to turn within a sleeve 14 fixed to the outer end of crank arm 10. This is the conventional arrangement enabling the pedal to turn or spin about on axis 1 6 which is perpendicular to the outer end of the crank arm 10. As will be obvious to those skilled in the art, the pedal 11 is for the left foot and the arrangement shown in the drawing would be duplicated for the right foot in the case of a bicycle for exercising, whether movable or stationary.
The pedal is centrally mounted on the upper end of another shaft or post 17. Shaft 17 is connected to the outer end of shaft 13 at a right angle thereto so that the shaft 1 7 is free to turn about its axis 18. This enables pedal 11 to have an additional mode of movement, namely to turn about the axis 1 8.
In the particular illustrated execution of my invention the lower end of shaft 1 7 is mounted in a rotary ball 1 9 mounted in a corresponding socket formed in the outer end of shaft 1 3 to provide a swivel connection of the pedal to rotary crank shaft 13. Such ball and socket connection of the lower end of shaft 1 7 to shaft 13 provides a still another mode of movement for the pedal 11.
That is to say, pedal 11 can swivel about a point 1 5 defined by the intersection of axes 1 8 and 1 6.
This is a third mode of freedom of movement provided for the pedal 11.
It should be noted that the ball and socket could be provided at the other end of the shaft 17, and if only the first two modes of movement for the pedal were desired the ball and socket would be omitted. In such an arrangement shaft 17 would be mounted in a bushing in the outer end of shaft 1 3 to solely turn about the axis 1 8.
Alternately, shaft 1 7 could be non-rotatably mounted to the shaft 1 3 and the pedal instead allowed to turn about axis 1 8 at its connection collar 20 at the upper end of post 1 7.
It will now be seen that multiple modes of movement are provided for the jllustrated exerciser pedal. The pedal can turn about axis 16, and about axis 18, and can also swivel about the ball and socket located at the point 1 5 where axes 1 6 and 1 8 intersect. What this means is that the user of the exerciser can be constantly changing the attitude of his feet, ankles and legs while pedaling so that a greater number of parts and muscles of the body come into play while pedaling. Heretofore, in conventional exercise bicycles it was possible for the body to assume only a single or same attitude while pedaling.
With the instant invention this is constantly changing to suit the needs of the user, and the user can therefore more nearly simulate a running or jogging gait while still in fact only pedaling.
Of course, in addition to all the above advantages, the device is low cost and if less than three modes of different movement are desired the device can be readily adapted thereto.
Although the device has been described with respect to pedaling with the feet, it will be obviousd to those skilled in the art that it is also applicable to pedal type exercisers for the upper part, such the wrists, arms and shoulders of the body. Additionally, it will be seen that my invention does not require any major changes in the remainder of bicycle exercisers. The change required to achieve the advantages of my invention is made splely at the pedals. Thus, the assembly illustrated in the drawing can be offered as an adaptor package for existing exercise bicycles.
Claims
1. A pedal-type exerciser comprising a crank arm and a pedal at the outer end thereof which is free to turn with respect to said crank arm about an axis which is perpendicular to said crank arm, said pedal being free to turn about an axis which is perpendicular to said first axis.
2. An exerciser as in Claim 1, said pedal also being free to swivel about a point defined by the intersection of said two axes.
3. A pedal exerciser comprising a crank having a foot pedal at the outer thereof, said pedal being swivel connected to said crank.
4. A pedal exerciser, comprising a crank arm, a perpendicular sleeve connected to one end of said
