With reference to

FIGS. 1 through 4

, a quadriceps exercise apparatus


10


in accordance the present invention is disclosed. The quadriceps exercise apparatus


10


includes a base structure


12


having a central support member


14


with a first end


16


to which a user support structure


18


is secured and a second end


20


to which a resistance assembly, more particularly, a weight stack,


22


is secured. A single cable


24


actuates the weight plates


28


of the weight stack


22


. The single cable


24


is secured to the weight stack


22


for movement by an individual using the quadriceps exercise apparatus


10


.




The central support member


14


is preferably a tubular member with a rectangular cross section. As with all of the structural components used in the manufacture of the present quadriceps exercise apparatus


10


, the central support member


14


is formed from steel, although those skilled in the art will appreciate the other materials which may be used in the construction of the disclosed exercise apparatus without departing from the spirit of the present invention.




The weight stack


22


is a conventional, vertically oriented weight stack. The weight stack


22


includes vertical support members


26


aligned to support a stack of weight plates


28


which are moved via the pulley system discussed below in greater detail. The weight stack


22


is covered by a protective sleeve


30


positioned about the weight stack


22


. The weight stack


22


is vertically oriented and includes a front face


32


, a rear face


34


, a left side


36


and a right side


38


.




As will be discussed below in greater detail, the weight stack


22


is actuated by a single cable


24


which controls the movement of the weight plates


28


. The central portion


40


of the cable


24


is passed through a first pulley


42


. A coupling member


44


directly couples the stack of weight plates


28


to the first pulley


42


in a conventional manner. Opposite strands


46


,


48


of the cable


24


then respectively extend over first and second upper pulleys


50


,


52


before exiting the weight stack


22


from the left and right sides


36


,


38


thereof. The first and second strands


46


,


48


are then directed downwardly and outwardly for engagement by the user.




The respective ends


54


,


56


of the first and second strands


46


,


48


are each provided with stop members


58


. As those skilled in the art will readily appreciate, the stop members


58


control motion of the single cable


24


to allow exercise by pulling the first strand


46


alone, the second strand


48


alone, or both strands at the same time.




First and second lateral support members


60


,


62


are also secured to the second end


20


of the central support member


14


. The lateral support members


60


,


62


extend outwardly from the longitudinal axis of the central support member


14


and away from the first end


16


of the central support member


14


. The combination of the cental support member


14


, the first lateral support


60


and the second lateral support


62


create a tripod foundation structure. This foundation structure supports the remaining components of the quadriceps exercise apparatus


10


, as well as users of the present exercise apparatus.




As mention above, the first and second strands


46


,


48


of the cable


24


exit the weight stack


22


after passing over the first and second upper pulleys


50


,


52


. After exiting the weight stack


22


, the first and second strands


46


,


48


move downwardly respectively along the left and right sides


36


,


38


of the weight stack


22


until they pass through the first and second pivoting pulleys


64


,


66


secured to the sides of the weight stack


22


.




The first and second pivoting pulleys


64


,


66


are respectively coupled to mounting plates


68


,


70


on the left and right sides


36


,


38


of the weight stack


22


. The pivoting pulleys


64


,


66


are mounted in such a manner that they are able to pivot about a vertical axis substantially parallel to the longitudinal axis of the weight stack


22


. In this way, the strands


46


,


48


of the cable


24


respectively exit the weight stack


22


along the left and right sides


36


,


38


thereof, pass over the pivoting pulleys


64


,


66


and are ready for engagement by the user. The distal ends of each strand


46


,


48


of the cable


24


may be fitted with a wide variety of user interfaces


49


known to those skilled in the art. The user interfaces should be chosen from the group designed specifically for attachment to the lower legs and feet of exercisers. Such interfaces are well known in the art, and those skilled in the art will appreciate the many interfaces which may be used without departing from the spirit of the present invention.




Each pivoting pulley


64


(the first pivoting pulley will be described here in detail) includes a frame


72


with a central pivot


74


for rotatably supporting a pulley member


76


. The frame


72


is formed so as to support the pulley member


76


. The frame


72


further includes a cylindrical coupling member


78


shaped and dimensioned for pivotal attachment to the mounting plate


68


. The coupling member


78


is secured to the mounting plate


68


such that the pivoting pulley


64


may freely pivot about the axis extending through the center of the cylindrical coupling member


78


. The cylindrical coupling member


78


provides an opening through which the cable


24


passes as it extends downwardly from the upper pulleys


50


,


52


toward the pulley member


76


. In this way, the cable


24


passes along the axis about which the pivoting pulley


64


pivots to provide greater freedom of motion as an individual attempts to draw the cable in various directions during exercise.




Since the pivoting pulley


64


permits a great degree of flexibility with regard to the angle at which the cable


24


is drawn from weight stack


22


, the inclusion of the present pivoting pulley


64


,


66


at the sides of the weight stack


22


greatly increases the flexibility of the present exercise apparatus


10


.




The first and second pivoting pulleys


64


,


66


extend outwardly, and in opposite directions, from the lower end


82


of the weight stack


22


such that the first and second strands


46


,


48


are directed to a position approximately in line with the legs of an individual utilizing the present quadriceps exercise apparatus. Given that the pivoting pulleys


64


,


66


are secured adjacent the lower end of the weight stack


20


, the pivoting pulleys


64


,


66


will be slightly above the ground upon which the user stands. Specifically, the pivoting pulleys are preferably positioned at height of approximately 36 inches from the center of the pulley relative to the ground upon which the user stands, although the pivoting pulleys may be positioned at various heights without departing from the spirit of the present invention.




Based upon the orientation of an exerciser properly using the present quadriceps exercise apparatus, the user support structure


18


consists of a rearwardly angled, and upwardly extending, user support bar


80


positioned for gripping by the user. The bar


80


includes a horizontal grip


81


for user comfort and security.




The combination of the vertically oriented weight stack


22


, the central support member


14


and the rearwardly angle user support bar


80


creates a convenient open space for exercising. Specifically, an individual enters the apparatus and is free to stand upright while exercising or bend forward while exercising. The individual is also free to swing his or her legs through a small or large arc without worrying that the frame of the apparatus will impede leg motion. Regardless of the individuals chosen exercise position, the narrow profile of the apparatus opens the range of leg motions individuals may add to his or her exercise routine.




In use, the individual will be stand facing away from the weight stack


20


. The individual will then secure the user interfaces


49


to his or her ankles or feet and grip the user support bar


80


. The individual will then swing his or her legs away from the weight stack


22


to generate resistance from the weight stack


22


. Movement of the individual's legs in this way acts to work the quadriceps of the individual. As shown in

FIGS. 1

,


3


and


4


, the flexibility provided by the pivoting pulleys


64


,


66


permits the individual to move in a wide variety of paths in order to equally exercise a wide variety of quadriceps muscles.




While it is disclosed above that the present quadriceps exercise apparatus is designed to be used with the user standing and facing away from the weight stack, the versatility provided by the design of the exercise apparatus provides users with virtually unlimited possibilities with regard to the range of exercise motions that may be accommodated by the present exercise apparatus.




With reference to

FIGS. 5 and 6

, a hamstring exercise apparatus


110


in accordance the present invention is disclosed. The hamstring exercise apparatus


110


is substantially similar to the quadriceps exercise apparatus


10


discussed above. As such, the hamstring exercise apparatus


110


includes the base structure


112


discussed above, as well as the cable arrangement discussed above.




Based upon the orientation of an exerciser properly using the present hamstring exercise apparatus


110


, the user support structure


116


consists of a support handle


180


secured to the front face


132


of the weight stack


122


. While a support handle


180


is disclosed in accordance with the present invention, other user support structures may be employed without departing from the spirit of the present invention.




In addition, the positioning of the pivoting pulleys


164


,


166


varies slightly to accommodate the specific exercises being performed with the hamstring exercise apparatus


110


. Specifically, the first and second pivoting pulleys


164


,


166


are preferably positioned at height of approximately 10 inches from the center of the pulley relative to the ground upon which the user stands, although the pivoting pulleys


164


,


166


may be positioned at various heights without departing from the spirit of the present invention.




Given the positioning of individuals using the present hamstring exercise apparatus


110


, the central support member


116


may be provided with a user support platform


184


upon which an individual may stand while performing exercises.




In use, the individual will be stand facing the weight stack


122


. The individual will then secure the user interfaces


149


to his or her ankles or feet and grip the user support handle


180


. The individual will then swing his or her legs away from the weight stack


122


to generate resistance from the weight stack


122


. Movement of the individual's legs in this way acts to work the hamstrings of the individual. As shown in

FIGS. 5 and 6

, the flexibility provided by the pivoting pulleys permits the individual to move in a wide variety of paths in order to equally exercise a wide variety of hamstring muscles.




While it is disclosed above that the present hamstring exercise apparatus is designed to be used with the user standing and facing away from the weight stack, the versatility provided by the design of the exercise apparatus provides users with virtually unlimited possibilities with regard to the range of exercise motions that may be accommodated by the present exercise apparatus.




While the preferred embodiments have been shown and described, it will be understood that there is no intent to limit the invention by such disclosure, but rather, is intended to cover all modifications and alternate constructions falling within the spirit and scope of the invention as defined in the appended claims.
