1. Field of the Invention
The present invention relates to an exercise apparatus for strength training and physical therapy of a user thereof.
More particularly, the present invention relates to an exercise apparatus having a weight table which moves between a first and second position thereof.
2. Background Information
An important feature of the present invention is the provision of an exercise apparatus in which the resistance in an exercise cannot only be adjusted but can be totally reversed.
According to the apparatus of present invention, the weights are easier to change because the bars are almost vertical and the weights themselves are horizontal at the lowest point in each repetition (rep). However, the weights are at an angle at the highest point in each rep and when locked making it easier for the user to change the weights.
The present invention includes resistance which, unlike most of the prior art exercise machines, is never constant.
In an exercise according to the present invention, every rep starts with the pertinent muscle at its most-contracted point in the chosen range of motion in the exercise and with zero resistance. Then, as the muscle is extended, the resistance gradually and smoothly increases until, at the most-extended point of the muscle in each rep, the resistance is at its maximum according to the weight that has been added in discs. As the rep is completed and the muscle is again brought to its most contracted point, the resistance is again returned to zero.
The range of motion in an exercise using the apparatus of the present invention is completely adjustable, in both length and placement, with the simple movement of two adjuster pins. Within this range of motion, which is selected by the user, there would still be the variable resistance described above
Accordingly, the user will be able to decide where the maximum resistance is to be in an exercise rep. It is recommended that the maximum resistance be set for the strongest point for the muscle. However, many lifters may disagree and want the maximum resistance at another point. The apparatus according to the present invention will offer this capability to the lifter.
Every exercise according to the present invention will have two preset plate-loaded weights. Drop sets have been preferred by users who are serious about building muscle size and strength. However, such drop sets are usually too problematical for most manufactures to implement. With the apparatus according to the present invention, the problems are eliminated. With an upper body exercise, the user will smoothly and easily switch between weights by means of a foot-pedal and with lower-body exercises by means of a hand latch.
The switching system for the apparatus according to the present invention is arranged so that, as the user approaches the machine for an exercise, the user will find the weights secured in their almost upright position.
When the user hits the foot-pedal once, the main weight bar is released from its locked position and the user would preferably do just one rep at this lighter weight which would give the user the opportunity to check the user's positioning, grip and to give notice to the user that the user's muscles have heavy work ahead. Then, when the user hits the foot-pedal again, the user will use the heavier of the two chosen weights where the user is able to do every possible rep. Once the user hits the foot-pedal a third time, the user will be returned to the lighter of the two preset weights such that the user can do several more bonus reps thus reaching muscle failure the second time in the same set. Many lifters use the light-day, heavy-day routine. With the apparatus according to the present invention, the user would have a light day and heavy day all in one.
The apparatus according to the present invention is counterbalanced. The weight carriers without weight discs have a certain amount of weight, but this weight can be counterbalanced so that the weakest user such as a patient attempting to recover from an injury, can effectively use the apparatus according to the present invention. Also, each handle used can be counterbalanced.
For many, the counterbalance for the main weight carrier might not be needed. However, the secondary weight carrier would almost always be counterbalanced. Some users would possibly resent the counterbalancing. If this were the case, the whole counterbalancing bar can be removed.
The resistance in the apparatus according to the present invention is completely reversible: The range of motion in an exercise will be completely at the user's discretion. This is accomplished by means of a slider which can be stabilized anywhere between the highest-degree point of the pivoting bar to the lowest usable point. However, the slider or connector can be moved past the center pivoting point to where the resistance is completely reversed. Taking this factor into account, a deltoid exercise can be switched easily into a lateral exercise; a back exercise can become a pec exercise; a triceps exercise can become curls, etc.
The apparatus according to the present invention removes the conflict between gravity and movement of a muscle. In the prior art, the straight-up-and-down resistance of gravity machines, as illustrated by free weights and by the weight-stack or “selectorized” machines, problems exist adapting this straight-line motion to a single muscle.
A user who wants to do an isolation-type exercise for one muscle or pair of muscles has to confront this conflict head-on and make accommodation for it. In virtually every case today, it is a matter of watching the user's form, which the user may do acceptably one day but not another.
Most of the prior art exercise machines are such that the lifter does not know exactly how much work was done in the previous sessions when doing the same exercise. In the apparatus according to the present invention, the variable resistance combined with the fact that a lifter would know how many reps the user had completed in each set, gives the user a unique and helpful opportunity to really challenge the user to do better than ever before. Counting the reps when using most prior art machines is pure guesswork, since the resistance is high even when the muscle is at full contraction. With most of the prior art machines, a lifter can always do another rep, though that rep may be a tiny bit shorter than a full one (then shorter and shorter), but when does the user stop counting?
Therefore, the primary feature of the present invention is the provision of an exercise apparatus that overcomes the problems associated with the prior art machines and which makes a significant contribution to the exercise machine art.
A further feature of the present invention is the provision of an exercise machine which selectively reverses the resistance.
A further feature of the present invention is the provision an exercise apparatus that enables a user thereof to easily load and remove weights therefrom.
Other features and advantages of the present invention will be readily apparent to those skilled in the art by a consideration of the detailed description of a preferred embodiment of the present invention contained herein.
The present invention relates to an exercise apparatus for strength training and physical therapy of a user thereof. The apparatus includes a frame having a first side and a second side spaced relative to the first side and at least one spacer extending between the sides. An axle is rotatably supported by the frame, the axle having a first and a second end. An arm has a first and a second extremity, the first extremity of the arm is rigidly secured to the first end of the axle. A handle extends from the second extremity of the arm such that in use of the apparatus, when the user moves the handle in an orbital direction about the axle, the axle is rotated relative to the frame.
A weight table is movably supported by the frame. A weight guide extends from the weight table for permitting weights to be guided onto the weight table. A first table support has a proximal and a distal end, the proximal end being pivotally secured to the frame at a first location. The distal end is pivotally secured to the weight table at a first disposition. A second table support has a first and a second termination, the first termination being pivotally secured to the frame at a second location which is spaced relative to the first location. The second termination is pivotally secured to the weight table at a second disposition, the second disposition being spaced relative to the first disposition. The arrangement is such that, in use of the apparatus, the weight table is moved from a first position adjacent to the frame to a second position away from the frame. The weight table is inclined relative to the frame when in the first position thereof for facilitating guiding weights onto and along the weight guide onto the weight table. The weight table is disposed substantially horizontally when in the second position thereof. A transmission is provided for transmitting rotational movement of the axle when the axle is rotated relative to the frame, the rotational movement of the axle being transmitted to the weight table for moving the weight table between the first position and the second position thereof.
In a more specific embodiment of the present invention, a further axle is rotatably supported by the frame, the further axle having a further first and a further second end.
Also, a further arm has a further first extremity and a further second extremity. The further first extremity of the further arm is rigidly secured to the further first end of the further axle.
Moreover, a further handle extends from the further second extremity of the further arm such that in use of the apparatus, when the user moves the further handle in a further orbital direction about the further axle, the further axle is rotated relative to the frame.
Additionally, a further weight table is movably supported by the frame.
A further weight guide extends from the further weight table for permitting weights to be guided onto the further weight table.
Also, a further first table support has a further proximal and a further distal end, the further proximal end being pivotally secured to the frame at a further first location. The further distal end is pivotally secured to the further weight table at a further first disposition.
Furthermore, a further second table support has a further first termination and a further second termination, the further first termination being pivotally secured to the frame at a further second location spaced relative to the further first location. The further second termination is pivotally secured to the further weight table at a further second disposition, the further second disposition being spaced relative to the further first disposition. The arrangement is such that, in use of the apparatus, the further weight table is moved from a further first position adjacent to the frame to a further second position away from the frame;
The further weight table is inclined relative to the frame when in the further first position thereof for facilitating guiding weights onto and along the further weight guide onto the further weight table. The further weight table is disposed substantially horizontally when in the further second position thereof.
An interlock mechanism has a first and a second mode such that, when the mechanism is in the first mode, the weight table and the further weight table are connected. However, when the mechanism is in the second mode, the weight table and the further weight table are disconnected relative to each other. The arrangement is such that, when in the first mode, the user by moving the handles in said orbital directions, the weight tables moves between the first and second positions thereof. However, when in the second mode, the user by moving the handles in said orbital directions, the weight table only moves between the first and second position thereof.
A foot pedal is operatively connected to the interlocking mechanism for selective operator movement of the mechanism between the first and the second mode.
The first side of the frame includes a first and second member, the first member having an end and a further end. The second member has an extremity and a further extremity.
Also, the first side also includes a base from which the members extend and a platform supported by the base.
A beam is secured to the end of the first member and a transverse beam extends between the beam and the extremity of the second member.
The second side of the frame is a mirror image of the first side of the frame.
Also, the at least one spacer includes a first and a second support, the supports extending between the beams of the sides of the frame. The second support is disposed spaced and parallel relative to the first support.
The axle and the further axle are rotatably supported by the first and the second support of the frame such that the axles are disposed spaced and parallel relative to each other.
Further, the orbital direction and the further orbital direction are opposite relative to each other.
The weight tables are selectively movable in an eccentric path and the weight tables, when disposed in the first position thereof, are disposed substantially parallel to the transverse beam.
The transmission further includes a reel which is rigidly secured to the axle. A further reel is rigidly secured to the further axle and a drum is rotatable secured to the frame.
A flexible drive extends between the reel and the drum and a further flexible drive extends between the further reel and the drum. The arrangement is such that when the handles are moved by the user, the drum is rotated relative to the frame.
Additionally, a lever is rigidly secured to one of the table supports adjacent to the frame such that the lever is disposed angularly relative to the one of the table supports. The lever has a first and a second anchor.
A connector has a first and a second end, the first end of the connector being connected to the drum. The second end of the connector is selectively connected to the first or the second anchor. The arrangement is such that when the second end of the connector is connected to the first anchor, when the user moves the handles, the weight table is moved from the first towards the second position thereof. However, when the second end of the connector is connected to the second anchor, when the user moves the handles, the weight table is moved from the second position towards the first position thereof.

Moreover, a further handle 80 extends from the further second extremity 78 of the further arm 74 such that in use of the apparatus 10, when the user moves the further handle 80 in a further orbital direction 82 about the further axle 68, the further axle 68 is rotated as indicated by the arrow 84 relative to the frame 12.
Additionally, as shown in
A further weight guide 88 extends from the further weight table 86 for permitting further weights 90 to be guided onto the further weight table 86.
Furthermore, a further second table support 102 has a further first termination 104 and a further second termination 106, the further first termination 104 being pivotally secured to the frame 12 at a further second location 108 spaced relative to the further first location 98. The further second termination 106 is pivotally secured to the further weight table 86 at a further second disposition 110, the further second disposition 110 being spaced relative to the further first disposition 100. The arrangement is such that, in use of the apparatus 10, the further weight table 86 is moved from a further first position adjacent to the frame 12 to a second position thereof away from the frame 12 as shown in

A connector 158 has a first and a second end 160 and 162, the first end 160 of the connector 158 being connected to the drum 144. The second end 162 of the connector 158 is selectively connected to the first or the second anchor 154 and 156 respectively. The arrangement is such that when the second end 162 of the connector 158 is connected to the first anchor 154 as shown in
The pedal 114 includes a first operation in which both weight tables 36 and 86 are locked against movement thereof, a second operation in which the weight table 36 is unlocked for movement thereof, a third operation in which both of the weight table 36 and 86 are unlocked for movement thereof, a fourth operation in which the further weight table 86 is locked against movement thereof and a fifth operation in which both weight tables 36 and 86 are again locked against movement thereof.
In operation of the apparatus 10, the user moves the handles 32 and 80 such that the handles move in the orbital directions 34 and 82 respectively. Such movement is transmitted to the weight table 36 or to both weight tables 36 and 86. When the interlocking mechanism 112 is disconnected, only the table 36 and the weights 40 thereon will be moved. However, when the interlocking mechanism 112 is connected by operation of the user operated foot pedal 114, both of the weight tables 36 and 86 are moved as a result of movement of the handles 32 and 80. Additionally, by disconnecting the second end 162 of the connector 158 from the first anchor 154 and connecting such second end 162 of the connector 158 to the second anchor 156, effort will be required on the part of the user in a reverse direction of the orbital and further orbital direction 34 and 82 respectively, thus providing further exercise configurations.
The exercise apparatus according to the present invention provides an arrangement in which weights can easily be added or removed from both weight tables and the direction of movement of the weight tables between the first and second positions thereof can be readily reversed by changing the linkage of the connector from the first to the second anchor.
