Some embodiments are configured to receive one or more safety bars to set a starting position of an exercise. Some embodiments include a training partner assistantship feature for a training partner to assist the user by imparting a secondary force on the machine. The configuration of the cable-pulley variable resistance system may be in any manner based on the exercise.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to weightlifting machines with weight stack systems to provide an increasingly variable load over the concentric range of the exercise and provide assistantship to perform a variably decreasing overload over the eccentric range of the exercise.

2. Brief Description of the Prior Art

Muscle groups have strength curves in which they can exert a maximum force output due to a mechanical advantage at a particular position or range along its motion. Resistance applied to the strong range of an exercise motion or muscle group will allow for the greatest amount of resistance to be used and it will develop the muscles, tendons, ligaments, and bones at a faster rate than if the resistance was only applied to the weak range of an exercise motion or muscle group. The amount of resistance capable of being handled over the strong range of an exercise motion or muscle group is disproportionately greater than the amount of resistance capable of being handled over the weak range due to a mechanical advantage of the limbs involved during the exercise.

As such it is desirable to increase the amount of resistance applied over the strong range of motion for an exercise motion or muscle group during the concentric phase of the exercise as well as the eccentric phase of the exercise. Moreover, yielding isometrics in which you withstand a heavy resistance preferably as you hold a strong position for time is desirable for producing a high force output. Lastly, overcoming isometrics allows for the maximum force possible to be generated for an exercise motion or muscle group because you attempt to overcome a high level of resistance such as an immovable object as you assume a strong position preferably. This is true because of the inverse relationship between the force developed by a muscle or group of muscles and the velocity of an external load. Simply, the faster you move an external load the less force you can develop and the slower the external load moves the more force you can develop.

In view of the above it is desirable to vary the resistance increasingly along the concentric and eccentric ranges of the exercise to match the strength curves of the muscle groups involved as many existing weightlifting machines with weight stack systems do not provide this benefit as the primary source of resistance. There are weightlifting machines with secondary sources of variably increasing resistance, but they are limited as they are called supplementary for a good reason. For example, secondary sources of variably increasing resistance will usually provide a low amount of resistance to supplement the primary source of resistance to allow for an incremental progression for the total amount of resistance selected. As such the weightlifter must handle the fixed amount of primary resistance throughout the range of motion which does not allow the weightlifter to handle their maximum amount of resistance during the strong range of motion. Usually, the resistance is increasingly varied over the concentric and eccentric phases of an exercise by using a gravitational mass such as a weight stack system and resilient materials such as elastic bands or torsional springs in combination or alone. Sometimes electromechanical devices are used to provide increasingly variable resistance.

In U.S. Pat. No. 4,546,971 to Paul Raasoch (1985) a user exercises the muscles of the human body by movement through an exercise stroke in which concentric and eccentric weights are selected to provide exertion to a bodily muscle function.

In U.S. Pat. No. 5,328,429 to Potash et al. (1994) an attachment for a weight stack provides a downward force to the weight stack during the eccentric portion of the exercise through the use of a drive motor and an eccentric force control cable adopted to be coupled between the drive motor and the weight stack.

In U.S. Pat. No. 5,669,861 to Lanny J. Toups (1997) a weight device creates a controlled and infinitely variable resistance by multiplying the weight selected on a weight stack over the concentric portion of the exercise. The device provides isokinetic and isotonic resistance. A device that multiplies the selected weight amount on the weight stack to provide increasingly variable resistance over the concentric portion of the exercise.

In U.S. Pat. No. 4,953,855 to William D. Shields (1990) a split phase cam machine uses a cam split into two distinct phases and an independent weight stack for each phase of the cam. The weight stacks are labeled “starting” and “finishing” to allow for the performance of the “peak contraction” technique where a user selects less weight for the “starting” weight stack and more weight as needed to the “finishing” weight stack to forcefully squeeze the muscles when fully contracted and to hold this position for a few seconds.

In U.S. Pat. No. 9,656,116 to Giannelli et al. (2017) a first and second force resistance device is provided. The first being a weight stack and the second being a rotating wheel as an actuating device that is acted upon by the first resistance and the user's speed, velocity, force, energy, or power thereby causing the second resistance device to exert a second resistance that is non-linear (geometrically or exponentially) in proportion to the degree of effort done by the user.

In U.S. Pat. No. 6,447,431 to Millburn et al. (2002) a device for retrofitting onto or incorporating into a conventional weightlifting machine is provided. A load tank replaces or supplements a number of weight plates in a conventional weight stack, while a charge tank rests on the floor proximal to the weightlifting machine. A fluid control means is provided for alternatively filling the load tank with water stored in the charge tank and draining the fluid back into the charge tank from the load tank, as desired in proportion to the muscle fatigue of the weightlifter. This invention is based on the premise that weightlifting machines are commonly used in resistance training, where the amount of weight is fixed at an amount less than the weightlifting capacity of the weightlifter. As the weightlifter progresses through his repetitions, the muscles eventually fatigue. The muscles generally reach their capacity only during the last few repetitions. Thus, several sets of repetitions can be necessary for appropriate muscle building, making the first few repetitions wasteful. Therefore, this invention attempts to reduce or eliminate the initial, inefficient repetitions by employing a system that begin at a weight at the weightlifter's capacity and reduce the amount of weight throughout the exercise.

In U.S. patent application publication 20060252611 to Quick et al. (2006) an exercise machine with bench press, weight stack, and elastic bands provide variable resistance during the concentric contraction. Pushing motion on the bench press bar transmits the force to a series of wheels connected by flexible bands and to a pair of weight stacks positioned behind the bench press. The weight members of the weight stack are connected by pins such that an upward movement of the uppermost weight members causes a pulling force to be applied to successive lower weight members one at a time, thereby allowing incremental increase in the resistance force to the lifting motion of the user. Depending on the strength of the user, elastic bands are used because weight plates often jump from 5 to 10 pounds without the possibility for an increment in weight in between.

In U.S. Pat. No. 10,369,398 to Lagree et al (2019) an improved exercise machine with a variable resistance system to provide increasing resistance over the concentric portion of an exercise is provided. The improved exercise machine improves upon Pilates apparatuses by making the selection of variable resistance level clear to the user for continuous uninterrupted exercise. In addition, the direction of variable resistance can be changed immediately to provide the exerciser with another exercise to perform for circuit training benefits. The variable resistance system can be applied to strength training machines such as a pull down and shoulder press combination to optimize the circuit training benefits because of time saved from having to move from one apparatus to another and selecting the desired resistance level which often requires set up time.

In U.S. Pat. No. 4,627,615 to Nurkowski (1986) a progressive resistance mechanism suitable for use with a weightlifting machine provides increasingly variable resistance over the concentric portion of the exercise. The progressive resistance mechanism uses two or more weight stacks that are selectively and independently engaged having a selector post through each weight stack. Each selector post has a first pin for selecting a subset of weights and at least one selector post has a second pin for locking a slidable collar at selected distances along the post above the carriage. The upward-travelling carriage engages the various pre-set collars in sequence to lift the associated selector posts. The weight stacks depending from the selector posts are thus serially engaged during the course of a single user repetition.

In U.S. Pat. No. 4,620,704 to Shifferaw (1986) an exercise machine for muscle building uses resilient rods which are flexed and resist movement of a person using the machine to provide increasingly variable resistance over the concentric portion of the exercise.

In U.S. Pat. No. 4,492,375 to Richard E. Connelly (1985) an exercise apparatus provides variably increasing resistance to the concentric range of the exercise by using elastic bands or torsional springs.

In U.S. Pat. No. 4,540,171 to Clark et al (1985) an apparatus for muscular exercise is provided where the user conducts a repetitive motion under load with the eccentric range of the exercise being loaded with more load than the concentric range of the exercise.

For Raasoch's disclosure, it requires more weight stack space, more weight stack plates, and cannot be incorporated towards existing weight stack systems found on weightlifting machines without a significant change to the mechanical parts and/or its assembly. For Potash's et al. disclosure, it does not provide increasingly variable resistance over the concentric portion of the exercise. For Toups's disclosure, it requires weight stack plates as the primary source of resistance. For Shields's disclosure, it requires at least two independent weight stack plates to create an increasingly variable resistance over the concentric range of motion. For Giannelli's et al. disclosure, it requires weight stack plates and a rotating wheel device as an actuating device to create the variable resistance in proportion to the degree of effort done by the user. For Millburn's et al. disclosure, it does not provide increasingly variable resistance over the concentric portion of the exercise. For Quick's et al. disclosure, it applies to a bench press machine with a free moving barbell, and it does not apply to strength training machines with moving handles that move in a fixed path with a weight stack and cable pulley system. For Lagree's disclosure, it does not provide supplementary resistance in 5 Pound increments or any amount of resistance between 0 and 10 (i.e., 0.5 lb., 21 lbs., 1 lb., etc.). So, incremental progression of 5 pounds is not possible and it will cause a significant limitation for a weightlifter's progress with the resistance level used. It cannot be incorporated towards existing weight stack systems found on weightlifting machines without a significant change to the mechanical parts and/or its assembly. For Nurkowski's disclosure, it requires at least two or more independent weight stacks to provide increasingly variable resistance over the concentric range of the motion. For Shifferaw's disclosure, it cannot be incorporated into the existing weight stack housing frames of weightlifting machines. For Connelly's disclosure, it cannot be incorporated into weightlifting machines utilizing a weight stack with cable pulley system along with the other mechanical parts known in the art. For Clark's disclosure, it does not provide variably increasing resistance over the concentric range of the exercise.

These disclosures heretofore known suffer from a few disadvantages:

• • 1) One cannot selectively select a primary source of variable resistance that is as inexpensive as elastic bands to provide more resistance towards the end of the motion where there is a mechanical advantage for the limbs involved to develop the muscles, tendons, ligaments, and bones at a faster rate than if most of the resistance was applied during the first half of the exercise motion.
  • 2) One cannot selectively add incremental resistance to a primary source of variably increasing resistance such as elastic bands to provide incremental progression of the resistance used to promote adding small amounts of resistance consistently over time as the way to progress a weightlifter's strength as the primary factor with the addition of repetitions and sets as the secondary factor when needed.
  • 3) One cannot utilize the ergonomic/biomechanical design features of weightlifting machines with weight stack and cable pulley systems while using a primary source of variably increasing resistance that is as cheap as elastic bands and perform assisted negative repetitions with variably decreasing resistance over the eccentric range of the motion.
  • 4) One cannot utilize the ergonomic/biomechanical design features of weightlifting machines with weight stack and cable pulley systems while using a primary source of variably increasing resistance such as elastic bands and have an exercise range of motion feature for performing yielding isometrics and overcoming isometrics for added exercise intensity and variation of training routine.

Accordingly, what is needed is an improved exercise machine. However, in view of the art considered as a whole at the time the present invention was made, it was not obvious to those of ordinary skill in the field of this invention how the shortcomings of the prior art could be overcome.

DETAILED DESCRIPTION OF THE INVENTION

In the following detailed description of the preferred embodiments, reference is made to the accompanying drawings, which form a part thereof, and within which are shown by way of illustration specific embodiments by which the invention may be practiced. It is to be understood that other embodiments may be utilized, and structural changes may be made without departing from the scope of the invention.

As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” include plural referents unless the content clearly dictates otherwise. As used in this specification and the appended claims, the term “or” is generally employed in its sense including “and/or” unless the context clearly dictates otherwise.

The phrases “in some embodiments,” “according to some embodiments,” “in the embodiments shown,” “in other embodiments,” and the like generally mean the particular feature, structure, or characteristic following the phrase is included in at least one implementation. In addition, such phrases do not necessarily refer to the same embodiments or different embodiments.

Referring now to FIGS. 1A-1E, an exemplary embodiment of a resistance band exercise machine 100 is disclosed. The resistance band exercise machine has a cable-pulley variable resistance system housing 102 and a cable-pulley variable resistance system 104. The cable-pulley variable resistance system has a top plate 106 (generally referred to as a “first attachment member”) with a resistance band hook 108 welded, bolted, or connected in any manner to the underside of the top plate. Another resistance band hook 108 (generally referred to as a “second attachment member”) is secured to the cable-pulley variable resistance system housing beneath the top plate's resistance band hook on the lower frame member. There can be multiple resistance band hooks.

The cable-pulley variable resistance system has one or more guide rails. The exemplary figures depict the one or more guide rails as a pair of uprights 110 welded, bolted, or connected in any manner to the cable-pulley variable resistance system housing and positioned such that the top plate rests on a pair of safety bars 112 when inserted into a safety bar hole 114.

Belts, cables, cams, pulleys, or any combination thereof may be used in the cable-pulley variable resistance system. The configuration of the cable-pulley variable resistance system may be in any arrangement based on the exercise. Since different exercises have different ranges of motion, the number of safety bar holes will vary. Also, the safety bars determine the starting position of an exercise. The cable-pulley variable resistance system has a primary source of variably increasing resistance (elastic resistance band 116) that is looped around the resistance band hooks as shown in FIG. 1C-1D. The cable-pulley variable resistance system may or may not have a pair of guide rods 148. This means that without the pair of guide rods the top plate will not have a shaft collar 150. A joined safety bar 118 may be used instead for convenience as shown in FIG. 1E. All types of resistance bands as well as springs may be used as a primary source of variably increasing resistance with the resistance band exercise machine.

On one side of the cable-pulley variable resistance system housing is a container 120 to hold items such as towels, cleaning agent spray bottle, water bottle, resistance bands, safety bars, etc. The material of the cable-pulley variable resistance system housing may be made of stainless steel or any other material known in the art.

Referring now to FIGS. 1F-1L, another exemplary embodiment of a resistance band exercise machine 100 is disclosed. This exemplary embodiment is the same as the one above shown in FIGS. 1A-1E with the addition of a training partner assistantship feature to the cable-pulley variable resistance system of having an input lifting arm 122 with a handle grip 124 that is welded, bolted, or connected in any manner to the top plate. Alternatively, the input lifting arm may have a shoulder padding 126 or both as shown in FIGS. 1K and 1L, respectively.

Referring now to FIGS. 1M-1P, another exemplary embodiment of a resistance band exercise machine 100 is disclosed. This exemplary embodiment is the same as the one above shown in FIGS. 1F-1L but with a different training partner assistantship feature of having a training partner assistantship cable-pulley system 128. The training partner assistantship cable-pulley system has an exercise handle attachment 130 on one end and a snap link hook 132 that connects to an O ring 134 on the other end that is welded or connected in any manner to the top plate. Any exercise handle attachment may be used.

Referring now to FIGS. 2A-2D, an exercise is performed through a full range of motion from start to end position stretching the resistance band without the help of a training partner 136.

Referring now to FIGS. 3A-3C, the training partner inserts additional pair of safety bars 112 into the safety bar hole after an exercise is performed to the end position to reduce the exercise's range of motion and perform isometrics.

Referring now to FIGS. 4A-4D, another exemplary embodiment of a resistance band exercise machine 100 is disclosed. The cable-pulley variable resistance system has the resistance band and a secondary source of variably increasing resistance (springs 168). An exercise is performed through a full range of motion from start to end position contracting against the resistance band then the springs approaching end position of an exercise. The springs are placed on the top plate into a recessed spring pocket 170 with another recessed spring pocket on the upper frame member of the cable-pulley variable resistance system housing to keep the springs in place at the end position of an exercise. The addition of the springs to the resistance band increases the variability in resistance level from start to end position of an exercise matching the user's muscle group strength curve. The springs may be placed on top where the recessed spring pocket is on the cable-pulley variable resistance system housing and held in place by any means known in the art. A plurality of springs from the cable-pulley variable resistance system may be used in the resistance band exercise machine and placement of the recessed spring pocket may be anywhere on the top plate and the cable-pulley variable resistance system housing. Any means known in the art other than the recessed spring pocket to keep the springs in place may be used in the resistance band exercise machine.

The resistance band exercise machine includes, but is not limited to, exercises from U.S. patent application publication 20190374814-A1. The resistance band exercise machine applies to all other exercises targeting different muscle groups in the human body.

The exercise from U.S. patent application publication 20190374814-A1 is shown in FIGS. 5-13 as an example of interaction between a user 162 and the resistance band exercise machine.

Operation—FIGS. 5, 6, 7, 8, 9, 10, 11, 12, and 13

The user performs the exercise with their hands on a platform 154 through full range of motion for a number of repetitions on the resistance band exercise machine against the resistance band that is variably increasing in resistance from start to end position of the exercise by wearing a harness or belt 164 having snap link hook suspended from it and configured to connect to a cable 142 as shown in FIGS. 5A-5C. When the user cannot perform another full range of motion repetition, the training partner inserts the safety bars into the safety bar hole to reduce the exercise's range of motion as shown in FIG. 6A. The user performs a number of partial range of motion repetitions and the training partner inserts the safety bars into the safety bar hole so that

the user can perform isometrics against the safety bars when they cannot perform another partial range of motion repetition as shown in FIGS. 6B and 6C. The user may begin the exercise with reduced range of motion by first performing a full range of motion repetition so that the training partner can insert the safety bars into the safety bar hole.

The user can add the springs by placing them on the top plate into the recessed spring pocket to perform the exercise through a full range of motion from start to end position contracting against the resistance band then the springs approaching the end position of the exercise as shown in FIGS. 7A-7C.

The user can perform full range of motion negative repetitions (lowering phase of an exercise; eccentric muscle contraction) only using training partners. One training partner lifts the user using a strap 138 with a strap handle grip 140 in this particular exercise because it's a bodyweight exercise while the other training partner assists by performing a much more powerful exercise than the exercise the user is going to perform to set the user to the end position of the exercise in order to perform full range of motion negative repetitions only. The powerful exercise the training partner performs in this scenario is deadlifts using an input lifting arm 122 with a handle grip 124 like one performing deadlifts using a trap bar or also known as hex bar as shown in FIGS. 8A-8F. In other non-bodyweight exercises, one training partner assisting by performing a more powerful exercise than the exercise the user will perform will be enough. In the absence of a training partner assistantship feature of having an input lifting arm 122 with a handle grip 124, the training partner may help the user get into the end position of an exercise by any means using exercise machine features for user to perform full range of motion negative repetitions only. Because the resistance band variably increases in resistance from start to end position of an exercise, it is easier to assist the user to get into the end position of an exercise than if fixed amounts of weights were used.

FIGS. 9A-9F, show another way the user can perform full range of motion negative repetitions only using training partners and the training partner assistantship cable-pulley system. In this scenario, the exercise the training partner performs is like pulling a rope as in a tug of war game. The difference between FIGS. 8A-8F and this is the training partner assistantship cable-pulley system. The configuration of the training partner assistantship cable-pulley system may be in any arrangement based on the exercise. With the training partner assistantship cable-pulley system, the direction of force applied by the training partner can be in any direction based on the configuration of the training partner assistantship cable-pulley system. This allows for any exercise to be performed by the training partner based on the configuration of the training partner assistantship cable-pulley system. Whereas in FIGS. 8A-8F, the direction of force applied by the training partner is upwards limiting the number of exercises that can be performed.

When the user cannot perform another full range of motion negative repetition only as shown in FIGS. 8A-8F, the training partners assist by lifting the user and inserting the safety bars into the safety bar hole so the user can perform negative partial range of motion repetitions as shown in FIGS. 10A and 10B. When then user cannot perform another negative partial range of motion repetition, the user performs isometrics against the safety bars as shown in FIG. 10C. The user may begin the exercise performing partial range of motion repetitions and end the exercise performing isometrics against the safety bars by having the training partners assist by lifting the user and inserting the safety bars into the safety bar hole as shown in FIGS. 10A-10C.

When the user cannot perform another full range of motion negative repetition only as shown in FIG. 9A-9F, the training partners assist by lifting the user and inserting the safety bars into the safety bar hole so the user can perform negative partial range of motion repetitions as shown in FIGS. 11A-11C. When the user cannot perform another negative partial range of motion repetition, the user performs isometrics against the safety bars as shown in FIG. 11D. The user may begin the exercise performing partial range of motion repetitions and end the exercise performing isometrics against the safety bars by having the training partners assist by lifting the user and inserting the safety bars into the safety bar hole as shown in FIGS. 11A-11D.

After the user is done performing partial range of motion repetitions and isometrics against the safety bars, the training partners can assist the user to perform negative partial range of motion repetitions as shown in FIGS. 12A-12C.

FIGS. 13A-13F, show the training partner assisting the user to get into the end position of the exercise by performing squats using the input lifting arm and the shoulder padding then inserting the safety bars into the safety bar hole so the user can perform partial range of motion repetitions then end the exercise performing isometrics against the safety bars.

Advantages

From the description above, a number of advantages of my resistance band exercise machine become evident:

• • 1) The user can perform full/partial range of motion push-up exercises in the prone position with their hands on the platform of the resistance band exercise machine against primary and secondary sources of variably increasing resistance.
  • 2) The user can perform full/partial range of motion push-up exercises in the prone position with their hands on the platform of the resistance band exercise machine against primary source of variably increasing resistance with isometrics using safety bars.
  • 3) The user can perform push-up exercises in the prone position with their hands on the platform of the resistance band exercise machine against primary and secondary sources of variably increasing resistance using full/partial range of motion negative repetitions only with the help of training partners.

This allows the user to contract against variably increasing resistance along the direction of the muscle group's muscle fibers.
  • 5) The user can perform isolation (single-joint) and compound (multi-joint) movement exercises against primary source of variably increasing resistance through full/partial range of motion with isometrics using safety bars.
  • 6) The user can perform isolation (single-joint) and compound (multi-joint) movement exercises against primary and secondary sources of variably increasing resistance using full/partial range of motion negative repetitions only with the help of training partners.

Accordingly, the reader will see that the resistance band exercise machine allows a user to perform exercises including exercises from U.S. patent application publication 20190374814-A1 through dynamic motion (full range motion and partial range of motion), full/partial range of motion negative repetitions only using training partners, and static position (yielding isometrics and overcoming isometrics) using primary and secondary sources of variably increasing resistance as well as safety bars in one machine. Also, the user can quickly change the resistance level and multiple users can perform push-up exercises in the prone position together assisting one another with no muscular effort lost. In addition, the user can perform more repetitions in the strong range of motion (from mid to end position of an exercise) using primary and secondary sources of variably increasing resistance with the help of training partners. Furthermore, the resistance band exercise machine has the additional advantages in that:

• • 1) It allows the user to perform exercises along the direction of the muscle group's muscle fibers with comfort and proper form using primary and secondary sources of variably increasing resistance, cable pulley system, and ergonomic/biomechanical design features of exercise machines.
  • 2) It allows the user to train a muscle group to its maximum strength capability by increasing the variability in resistance level using primary and secondary sources of variably increasing resistance to match a muscle group's strength curve.
  • 3) It allows the user to perform exercises using isometrics training protocol which is a combination of isometric and isotonic exercises in one machine.
  • 4) It allows the user to perform more full/partial range of motion negative repetitions only against variably decreasing resistances from primary and secondary sources of resistances with the help of training partners.

The advantages set forth above, and those made apparent from the foregoing description, are efficiently attained. Since certain changes may be made in the above construction without departing from the scope of the invention, it is intended that all matters contained in the foregoing description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
