BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to exercise machines, and more particularly to multistation weight machines, and still more particularly to a multistation captive stack weight system and apparatus that enables a user to achieve a full body workout, including a core workout, from a standing position exclusively, though numerous seated exercises are also possible.
2. Discussion of Related Art Including Information Disclosed Under 37 CFR §§1.97, 1.98
Multistation exercise and weight machines are well known. A number of major exercise machine manufacturers make and sell commercial and residential machines either dedicated to particular exercises or a small group of exercises designed to exercise small groups of muscles or, alternatively, machines designed to enable a user to perform a number of exercises and to address a wide range of muscles and muscle groups. Typically, the systems for stack machines include the use of one or more weight stacks, each comprising a plurality of weight plates penetrated by one or two generally vertical stabilizing rods and over which a cable and pulley system is arranged so that the stack may be lifted by pulling the cable in some direction from an upper or terminal pulley and using any of a variety of apparatus—a bar held in the hands, a plate pushed by the legs and feet, a padded bar moved radially with a body bend, and so forth. The number of plates lifted is typically determined by the placement of a pin under the lowest of the plates to be lifted and inserted through an indexing hole in a post disposed vertically through the middle of all of the plates and that is elevated along with the stack. In some machines the cable extending from the terminal pulley may extend directly to an implement held or moved by the user; in other machines, the cable may be disposed over a cam connected to the cable, the cam being connected to an element engaged and moved by the user, such that resistance can be distributed more evenly throughout a range of motion. Countless variations in station configuration, arrangement, and principles of operation have been tried, but most multistation systems are either lever or cable machines, while some are a combination.
Despite the maturity and the diversity that devices in the relevant technical art have now reached, no known multistation weight machine provides a user with the ability to achieve a full body workout while conducting all exercises in various standing positions. Furthermore, no system works using a plurality of handle receptacles or ports operatively connected to a single second class lever which is, in turn, connected to a single stack of weight plates and which are moved by a plurality of handles adapted for use in executing particular exercises and which are removably insertable in the handle ports.
BRIEF SUMMARY OF THE INVENTION
It is therefore a principal and primary object of the present invention to provide a new and improved multistation weight machine that enables a user to perform a complete workout from a standing position.
It is another object of the present invention to provide a new and improved weight machine in which most exercises are performed with the feet placed on the ground, thereby minimizing the risk of injury and requiring that core stabilizing and balancing muscles be recruited to perform exercises properly and smoothly.
A further object or feature of the present invention is to provide a multistation exercise machine that provides means to connect variously configured handles to a single second class lever, which is in turn connected to a single stack of weight plates.
Still another object of the present invention is to provide a stack system with multiple stations that enable a user to get a resistance training core workout from a standing position.
An even further object of the present invention is to provide a stack-based weight training apparatus for resistance training that enables users to easily and rapidly configure exercise stations for complex sport-specific exercises.

DETAILED DESCRIPTION OF THE INVENTION
Referring to FIGS. 1 through 16B, wherein like reference numerals refer to like components in the various views, there is illustrated therein a new and improved multistation exercise apparatus, generally denominated 10 herein.
FIG. 1 illustrates a first preferred embodiment of the inventive exercise apparatus, showing that in its most essential form the device includes a stable planar base 12, preferably comprising welded elements of structural carbon steel square tubing in either a square or rectangular configuration. Other base geometries are clearly possible and may be desirable when the system includes exercise stations additional or auxiliary to those shown in the illustrations herein. In the rectangular configuration, the base includes right and left base bars, 14, 16, and front and back base bars, 18, 20.
Extending substantially vertically from points proximate the back ends of right and left base bars are right and left rear vertical supports, 22, 24. Extending either substantially vertically, or more preferably angling slightly rearwardly, are right and left front vertical supports, 26, 28. Joining the right and left front and rear vertical supports are right upper and left upper horizontal side bars, 30, 32, and right lower and left lower horizontal side bars 34, 36. Joining right and left rear vertical supports are upper rear transverse bar 38 and lower transverse bar 40. As will be appreciated by reference to the drawings, the side and transverse bars are preferably disposed in a generally horizontal position, though angled orientations are possible. The combination of vertical and horizontally disposed bars creates an upright frame on which are disposed further structural and functional elements that constitute exercise stations. Further, the upright frame includes the weight rack that functions as the resistance for many lifts, and includes storage racks for handles.
Extending upwardly from the back ends of the right and left base bars are right and left axle supports, 42, 44, each of which includes a shaft or pin 46, 48. A lever axle 50 is pivotally disposed on each of the pins and operatively connects them such that they function together as the fulcrum for the single operational lever on which all resistance exercises are performed.
A plurality of handle receptacles 52, 54, 56 are securely affixed to the lever axle proximate the central region of the lever axle and extend slightly rearwardly so as to provide an opening for inserting handles for configuring the system to perform myriad exercises. Operatively connected to, and extending forward from the lever axle, is a lever arm in the form of a foot pedal 58 having a step plate 60 disposed on its end. An arcuate cam 62 is disposed medially on the foot pedal and includes frame elements 64 for structural support.
A pulley 66 and pulley support plate 68 are disposed on upper rear transverse bar 38, and a weight stack 70 is supported on a weight stack base plate 72 affixed to the lower rear transverse bar 40. The plates comprising the weight stack slide up and down on spaced apart, side-by-side rails 74 extending from the pulley support plate, through the weight stack, and to the weight stack base plate.
A 76 cable extends from a front termination point 78 on the foot pedal over pulley 66 and down to the upper end of a weight selector rod (not shown) having a plurality of holes that align with holes created by grooves in adjoining weight plates, such that by inserting a pin between plates and through a hole in the weight selector rod, the number of plates to be lifted in an exercise is determined (which apparatus and method is well known in the art). As will be appreciated by those with skill in the art, by having the weight cable disposed over a cam connected to the foot pedal, which is the central lever arm in the lever system, the radial translation of the foot pedal or of any handle connected to the lever axle through a handle receptacle results in the smooth linear translation of a portion of the weight stack upwardly.
Extending forward from the front of the base are right and left steps 80, 82, which enable a user to step on to and mount the apparatus to use the foot pedal for leg exercises, or to ascend to the chin or dip stations (described below). Upper right and left steps 84, 86 further facilitate an ascent to the stations that require some elevation.
Base exercises are conducted using the above-described foot pedal and handle receptacles as the operative connections to the lever axle. However, one or more auxiliary sets 88 of handle receptacles 90, 92, can also be provided for exercises that involve handle movement to the side of the base (see FIGS. 10-12B and FIGS. 15A-B).
Efficiency in use is substantially enhanced by the provision of a plurality of handle ports 94, 96, 98, in which various handles may be stored when not in use.
Completing the system elements that generally comprise the base system and which are installed on a substantially permanent basis, albeit adjustably installed, are a chin up station having adjustable chin up handles 100, 102, and a dip station having adjustable dip station bars 104, 106, each station structurally disposed on the right and left front vertical supports.
The chin up handles each include a grip 108 attached to an angled support 110 which extends from a sleeve 112 that is slidably installed over its respective vertical support. The sleeve includes an interior pin (not shown) that inserts into a hole 114 in the vertical support to secure the handle at a selected height as long as the handle is either under the influence of gravity or bears a load from a user. When the handle is pushed up, the pin releases from the hole and the handle may be slid up or down to be secured at another height.
The dip station bars are similarly adjustably installed on the right and left vertical supports. However, the adjustment mechanism differs slightly. In this instance, each bar includes a handle portion 116, a collar 118, a down tube 120, an angled brace 122, and a latch pin 124 rotatably installed in a pin barrel 126. The down tube includes a locking pin (not shown) disposed on the side facing the vertical support. When the latch pin is rotated outward from the vertical support, the handle portion can be tipped upward to release the pin, and the entire bar assembly can slide up or down according to the user's preferences. The locking pin can then be secured in another through hole 128 in the vertical support.
In addition to the chin up station and the dip station, other exercises and groups of exercises can be performed by configuring various body-engaging elements provided for use with the mechanical elements of the apparatus. These include a Y-shaped squat bar 130, a rowing bar 132, a multipurpose handle or bar 134, and a neck exercise attachment bar 136. The squat bar, rowing bar, and multipurpose bar each include a lower end configured to insert tightly in the handle receptacle boxes so that moving the element rotates the lever axle and raises or lowers a selected portion of the weight stack.
In addition to the larger bars, there may be provided an adjustable sliding clamp or locking collar 138 and handles 140, connected to the sliding clamp via cable, that may be used in connection with the multipurpose bar for setting up complex core exercises, such as those shown in FIGS. 10A-12B and 15A-16B.
Referring next to FIGS. 4A through 12B, there is shown in various schematic side views a number of exercises performed with the inventive apparatus configured using the above-described multistation elements.
Beginning first with FIG. 4A, there is shown a user prepared to lower himself into position to execute an assisted dip at the standing leg press and dip station. The user holds the dip station handles and lowers himself between the handles, allowing the weight selected on the weight stack to resist his fall (clearly, the selected weight must be less than the user's weight; otherwise, it would require muscular assistance by the arms to pull the user down). FIG. 4B shows how the radial motion of the foot pedal translates into a slightly arcuate drop for the user. At FIG. 4B the user is poised to execute a forward leaning dip with the assistance of the raised portion of the weight stack, which will drop as the user raises himself using principally his triceps, lower pectoralis major, and anterior deltoids for arm extension.
FIG. 4C shows a user at the starting position of the assisted chin up station, while FIG. 4D shows the same user of FIG. 4C having executed an assisted chin up. The principle of operation is essentially identical to that of the assisted dip.
FIGS. 5A and 5B show the multipurpose bar inserted into one of the handle receptacles so as to enable a user to push the bar with a single arm chest press including pelvic rotation and a forward lunge. This is but one of countless complex core exercises that recruit multiple muscle groups to move the load.
FIGS. 6A and 6B show the rowing bar inserted into a handle receptacle disposed at a low angle so as to enable a user to execute a chest row at a row/dead-lift station.
FIGS. 7A and 7B show a user executing a squat and calf raise at a squat/calf-raise station. This station is configured by inserting the squat bar into one of the medially disposed handle receptacles.
FIGS. 8A and 8B show a user executing a single leg press at the standing leg press station, while FIGS. 9A and 9B shows a user executing an adduction exercise at the same station.
FIG. 10 is a partial exploded upper right rear perspective view showing how the auxiliary extension is inserted into the open end 50a of the lever axle 50.
FIGS. 10A and 10B show a user executing a hip rotation exercise. This is made possible by configuring a striking/throwing station by inserting the multipurpose bar into one of the handle receptacles disposed on the end of the auxiliary extension 88. This motion simulates a batting motion made by a baseball player.
FIGS. 11A and 11B show a user executing an overhead pullover using the same striking/throwing station configuration shown in FIGS. 10A-10B.
FIGS. 12A and 12B show a user simulating a golf swing motion at the striking/throwing station.
FIGS. 13A-C show the slidable clamp 138 or locking collar adapted for providing adjustable attachment to the multipurpose bar or similar handles. The clamp includes a cylindrical sleeve 142 slidably placed over the end of the multipurpose bar. A bracket 144 extends from the sleeve and includes a hole 145 for the pivotal attachment of a rocker 146 with a bolt or pin 148. At its upper end, the rocker includes a cup 150 in which is disposed a compressed helical spring 152 which urges the rocker to pivot about the pin 148 and to move the upper portion outwardly from the multipurpose bar. This brings a brake shoe 154 disposed at the lower end of the rocker into contact with the multipurpose bar. Intermediate the upper and lower portions is an arm 156 that includes one or more holes 158 for the attachment of an S-hook 160, carabiner, or other quick release device suitable for attaching cable or chain to the clamp.
FIGS. 14A and 14B show the neck station attachment 162 for the multipurpose bar. This includes a slidable collar 164 having a T-bolt for releasably securing the collar at a predetermined position along the length of the bar. A pivot bar 166 is pivotally connected to the slidable collar and includes a padded end portion 168. As shown in FIGS. 15A and 15B, as the multipurpose bar is radially translated by the user executing a neck bend or flexion, the pivot bar pivots to compensate for the collar height changes.
Referring back to FIGS. 2A-2C, there is shown an alternative adjustable axle attachment 170 for configuring the apparatus for auxiliary exercise sets. This comprises a tube 172 for insertion into connection into lever axle 50 and an end plate 174 having an index pin 176 disposed on a flat spring 178 affixed at a single point 180 to the end plate. A handle 182 is cantilevered outwardly from the flat spring and may be pulled to bend the flat spring. The index pin may thereby be selectively engaged with or disengaged from a hole in the index plate in alignment with one hole in an arcuate array of holes 184 disposed in an adjustment disc 186 rotatably mounted on the end plate. A handle receptacle 188 is affixed to and extends outwardly from the adjustment disc for insertion of an exercise set handle 190. This permits a user to set the handle at starting positions through a range of degrees defined by the arc in the arcuate array of holes.
The above disclosure is sufficient to enable one of ordinary skill in the art to practice the invention, and provides the best mode of practicing the invention presently contemplated by the inventor. While there is provided herein a full and complete disclosure of the preferred embodiments of this invention, it is not desired to limit the invention to the exact construction, dimensional relationships, and operation shown and described. Various modifications, alternative constructions, changes and equivalents will readily occur to those skilled in the art and may be employed, as suitable, without departing from the true spirit and scope of the invention. Such changes might involve alternative materials, components, structural arrangements, sizes, shapes, forms, functions, operational features or the like.
Therefore, the above description and illustrations should not be construed as limiting the scope of the invention, which is defined by the appended claims.
