Exercise machine

Abstract

An exercise machine for development of women's bustlines and men's pectoral and deltoid muscles in which the user is seated and has a pair of padded rollers which can be rotated forwardly and inwardly by the upper arms of the user. A cable system extends from eccentric pulleys rotated by the exercise action of the user to an adjustable weight unit. The eccentric pulley varies the weight load during each exercise cycle to thus provide uniform exercise for the muscles.

Description

BACKGROUND OF THE INVENTION

1. FIELD OF THE INVENTION

The present invention relates to exercise machines for development of women's bustlines and men's pectoral and deltoid muscles.

SUMMARY OF THE INVENTION

The machine user is seated and has his upper arms engaged against padded rollers mounted on crank arms carrying eccentric pulleys thereon. A cable system extends from the eccentric pulleys to a variable weight load which can be adjusted prior to use. The eccentric pulley varies the applied weight during each cycle of use to thus provide uniform exercise.

The primary object of the invention is to provide an exercise machine for development of women's bustlines and men's pectoral and deltoid muscles by continuously varying the load applied during each exercise cycle.

Other objects and advantages will become apparent in the following specification when considered in light of the attached drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring now to the drawings in detail, wherein like reference characters indicate like parts throughout the several figures, the reference numeral 10 indicates generally an exercise machine constructed in accordance with the invention.

The exercise machine 10 includes a frame 11 having two pairs of spaced parallel posts 12 each pair being supported on one of a pair of spaced parallel base members 13. The spaced pairs of post frame members 12 converge slightly toward their upper ends. Horizontal transverse members 14, 15 and 16 connect each pair of posts 12 at spaced points therealong.

A base frame member 17 extends between and connects the base members 13 centrally thereof and an upper horizontal frame member 18 extends between and connects the frame members 16 intermediate their opposite ends. An upright seat post 19 extends upwardly from a foot 20 on each side of the machine 10. a horizontal brace 21 extends from the transverse frame member 14 intermediate the opposite ends thereof to the upper end portion of the seat post 19 for reasons to be assigned.

A pair of tubular braces 22 extend from the frame member 13 to the foot 20.

A padded seat 23 is mounted on the seat post 19 and has a padded back 24 extending upwardly therefrom. The padded back 24 is supported on the transverse frame member 15 adjacent its upper end and on a block 25 supported on the post 12 adjacent its lower end. The back 24 is sloped away from the seat 23 for the comfort of the user.

A pair of spaced parallel tubular guides 26 extend in parallel relation from the base frame member 17 to the upper frame member 18 between the pairs of posts 12. A second pair of tubular guides 26 are similarly mounted adjacent the first pair thereof. The guides 26 are each provided with a compression spring 27 encompassing its lower end. Two pair of spaced parallel upright post members 28 are mounted on a pair of spaced apart base blocks 29 arranged in spaced parallel relation on the upper frame member 18. A swivel arm 30 is mounted on each of the posts 28 and has a pulley 31 journalled therein. A pulley 32 is journalled in a yoke 33 between the guides 26. An elongate cylindrical rod 34 depends vertically from the yoke 33 and is provided with a conical point 35 on its lower end. The rod 34 has a plurality of vertically spaced horizontal bores 36 formed therein.

A plurality of weight bars 37 each have a pair of bores 38 adjacent opposite ends thereof through which the guides 26 extend. The bars 37 have a central bore 39 with its axis parallel to the bores 38 and intermediate the bores 38. The rod 34 is adapted to engage through the bores 39. A horizontal bore 40 extends transversely of each of the bars 37 in aligned relation to the bores 36 when the rod 34 is completely inserted within the weights 37. A pin 41 is adapted to be inserted through a selected one of the bores 40 in a weight 37 and through the aligned bore 36 in the rod 34. On lifting the pulley 32 and its yoke 33 the weights 37 lying above the pin 41 are raised while the remainder of the weights 37 rest on the springs 27. A weight element or bar 42 on top of the stack of bars 37 is provided with guide collars 43 to assist in guiding the weights 37 on the guides 26 as the yoke 33 is raised and lowered.

A pair of spaced parallel arms 44 are secured to each of the transverse frames 16 and extend outwardly therefrom. The inner ends of the arms 44 connected by a transverse frame piece 45. A tubular upright bearing 46 is secured to the outer ends of each of the arms 44 and a shaft 47 is journalled therein. A crank arm 48 is integrally formed on the lower end of each of the shafts 47 and has a padded roller 49 journalled on its lower end for rotation about a vertical axis. An L-shaped stop 50 is secured to the shaft 47 for engagement with the arm 44 to limit the inward swinging movement of the roller 49.

An eccentric pulley 51 is rigidly secured to the upper end of each of the shafts 47 and it should be noted that adjacent eccentric pulleys 51 are vertically spaced so as not to interfere with each other.

A cable 52 is trained under the pulley 32 in the yoke 33 and over the pulleys 31 which are also vertically spaced to align with the eccentric pulleys 51. The cable 52 then has its opposite ends extending to and secured on the adjacent eccentric pulleys 51.

In the use and operation of the invention the user seats on the seat 23 with his back against the back rest 24 and his shoulders between the padded rollers 49. His arms are raised so as to have the forward part of the upper arm engage the inner portion of the padded roller 49 on each side. The arms are then drawn forward moving the padded rollers 49 forward thus rotating the cranks 48, shafts 47 and the eccentric pulleys 51. The cable 52 winds onto the eccentric pulleys 51 and raises the pulley 32 and its yoke 33 to thus raise the rod 34 and any weight attached thereto by the pin 41. As the cranks 48 are rotated the larger portions of the pulley 51 contact the cable 52 so as to provide a greater leverage against rotation of the cranks 48 for any given number of weights 37.

The pin 41 is used to selectively determine the number of weights 37 which will be lifted by the rod 34.

Having thus described the preferred embodiment of the invention it should be understood that numerous structural modifications and adaptations may be resorted to without departing from the spirit of the invention.
