Abstract
A versatile grip structure for an exercise device consisting of a pair of parallel bars where the source of tension is applied directly between the two bars by the use of a cable attachment placed between the bars or weight bearing rods attached to the ends of the device between the two bars. The bars can be used interchangeably as a grip or as a support. The trainee can grip the device with their hands in the supine or prone position with the grip bar in their hands and the support bar resting on their forearms below the wrist for improved muscle isolation and reduced wrist strain. This design also provides the trainee with the option to use a "traditional grip" and "fat grip" where they hold only one or both bars in their hands respectively. This grip structure can be used in barbells, dumbbells, cable attachments and machine attachments.
Description
DESCRIPTION
A Versatile, Ergonomic Grip Structure Consisting of Parallel Bars and Method of Use Background Of The Invention A. Field of the Invention The present invention relates to the field of weight training, specifically, an ergonomic exercise grip structure which can be applied to cable attachments, machine attachments, barbells and dumbbells which enhances the performance of a number of exercises by reducing joint strain and discomfort while providing enhanced muscle stimulation. This invention overcomes the limitations of single bar grip structures and Swiss bar grip structures and gives trainees a solution that provides the benefits of both while eliminating their respective drawbacks.
Most barbells, dumbbells and machine attachments consist of a single bar grip structure.
When a trainee uses a single bar grip structure to perform an exercise, the centre of gravity is applied directly to the place where the trainee engages the bar. A trainee usually engages a single bar grip with their hands, but may also engage it with their upper back and hands when they perform squats. A trainee would also engage a single bar structure with the front of their lower thighs when they perform seated calf raise exercises.
While a single bar grip structure can be effective, it presents challenges to a trainee which can increase the chance of injury while providing inadequate stimulation to the targeted muscles.
One such challenge that single bar structures pose is that they can make it difficult for a trainee to keep their wrists in a straight, neutral position when performing exercises such as bicep curls, triceps extensions or straight arm pullovers. Keeping the wrists straight is beneficial in isolating the targeted muscles when performing these exercises.
It requires extra effort on the part of the trainee to keep their wrists in a straight neutral position when performing these exercises which can lead to wrist strain as well as under stimulation of the targeted muscles due to the disproportionate effort required to keep their wrists and the bar in the optimal position during the exercise.
A second challenge a trainee may face with a single bar grip structure is finding an ideal place on their upper back on which to place the barbell when they perform barbell squats.
A trainee has the option of performing a high bar squat where they place the barbell on their upper back above the spine of the scapula or low bar squats where they place the barbell on their upper back below the spine of the scapula. Proper bar placement is essential to maintain balance, minimize the chance of injury and isolate the targeted muscles when performing this complex, challenging movement which involves almost all muscle structures in the body with a special emphasis on the muscles and joints of the lower body. As a result of these challenges, a trainee may avoid performing barbell squats altogether or perform them in an ineffective manner which can lead to under stimulation of the targeted muscles or potential injury.
A third challenge that single bar grip structures pose to many gyms, in particular, home gyms, is that they do not permit a trainee to perform the seated calf raise exercise in which a trainee flexes or dorsiflexes their ankles in an effective, safe manner.
Seated calf raises are valuable for isolating and strengthening the lower legs and ankles.
The specialized equipment that enables the effective performance of this exercise can be cost prohibitive and may occupy space that a home or commercial gym cannot provide, forcing trainees to perform this valuable exercise with a single bar structure such as a barbell or cable attachment. Placing a single bar structure across the lower thighs of a trainee to perform seated calf raises can make it difficult to maintain balance while being very uncomfortable as the resistance presses into the trainee's thighs which increases the chance of injury and under development of the targeted muscles even if protective pads are placed on the bar.
In order to address these above challenges, many devices and machines have been developed. One such device is the Swiss bar structure which consists of a pair of horizontal parallel bars that are connected by one or sometimes several pairs of neutral grip bars which can be arranged at a multitude of angles to form a frame to which weights or cables can be attached which serve as the source of resistance and place the center of gravity between the horizontal parallel bars. Some of these neutral grip bars may be perpendicular to the horizontal bars or diagonal to them. The distance between the horizontal parallel bars is determined by the length of these neutral grip bars which can vary from being as short as 5 inches to as long as 10 inches as they must be long enough to accommodate the hands of the trainee.
The Swiss bar structure attempts to minimize wrist strain during bicep curls and triceps extensions by forcing the trainee to engage these neutral grip bars with a thumbs up, neutral grip in which their palms face one another. While this can reduce wrist strain as it makes it easier for a trainee to keep their wrists in a straight, neutral position, it does not enable the trainee to optimally engage the biceps or triceps muscles which benefit from a supine or prone grip which a Swiss bar structure is not intended to provide.
If a trainee tried to perform bicep curls or triceps extensions with a supine or prone grip on a Swiss bar structure, they would have to grab one of the two horizontal bars which are connected by the neutral grip bars. This, however, would be identical to the single bar grip that they would be trying to avoid while the connecting neutral grip bars may make it difficult for the trainee to grip the horizontal bars as they would get in the way of their hands, preventing an adequate grip on the horizontal bar which further reduces the effectiveness of the exercise.
If a trainee were to grip one of the Swiss bar structures horizontal bars with their hands, while letting the second horizontal bar make contact by resting on their forearms, they could theoretically perform bicep curls and triceps extensions in the prone and supine position while reducing wrist strain. However, the aforementioned distance between these horizontal bars prevents this approach from being effective due to the amount of mechanical leverage involved. If a trainee were to use this technique, the second closer horizontal bar would rest low on their forearms due to the distance between them which

In order to address these above challenges, many devices and machines have been developed. One such device is the Swiss bar structure which consists of a pair of horizontal parallel bars that are connected by one or sometimes several pairs of neutral grip bars which can be arranged at a multitude of angles to form a frame to which weights or cables can be attached which serve as the source of resistance and place the center of gravity between the horizontal parallel bars. Some of these neutral grip bars may be perpendicular to the horizontal bars or diagonal to them.

This, however, would be identical to the single bar grip that they would be trying to avoid while the connecting neutral grip bars may make it difficult for the trainee to grip the horizontal bars as they would get in the way of their hands, preventing an adequate grip on the horizontal bar which further reduces the effectiveness of the exercise.
If a trainee were to grip one of the Swiss bar structures horizontal bars with their hands, while letting the second horizontal bar make contact by resting on their forearms, they could theoretically perform bicep curls and triceps extensions in the prone and supine position while reducing wrist strain. However, the aforementioned distance between these horizontal bars prevents this approach from being effective due to the amount of mechanical leverage involved. If a trainee were to use this technique, the second closer horizontal bar would rest low on their forearms due to the distance between them which
2 would move the center of gravity towards their elbows resulting in excess mechanical leverage. This mechanical leverage dilutes the effectiveness of the exercise and results in under stimulation of the targeted muscles while also being uncomfortable on the trainee's forearms rendering this technique impractical and ineffective.
A trainee also cannot use a Swiss bar structure to perform barbell squats as the distance between the horizontal parallel bars is too great to safely place and balance it on their upper back. The joining neutral grip bars would also add further discomfort and instability making this application impractical and potentially dangerous.
The Swiss bar structure also does not lend itself well to the seated calf raise exercise. The seated calf raise is performed when the trainee orients the bar so that it is perpendicular to their thighs and then places it across the front of their thighs just above the knee in the seated position. The Swiss bar is ineffective due to the distance between the horizontal parallel bars which places the center of gravity further up the trainee's thighs towards their hips which over utilizes mechanical leverage and greatly reduces the effectiveness of the exercise. The neutral grip bars of the Swiss bar also reduce the effectiveness of this exercise by pressing onto the thighs of the trainee making it uncomfortable.
The ergonomic exercise grip structure proposed in this application addresses the aforementioned challenges and shortfalls of single bar grip and Swiss bar structures as it provides a trainee with the means to exercise in a safe productive manner while reducing the potential for injury on a multitude of exercises including but not limited to bicep curls, triceps extensions, straight arm pullovers, squats and seated calf raises.
The ergonomic exercise grip structure proposed in this application delivers these benefits by its unique structure which consists of two straight horizontal parallel bars which are placed much closer together than those of a Swiss bar structure. The ergonomic exercise grip structure enables the close placement of the straight horizontal parallel bars because there are no neutral perpendicular or diagonal hand grip bars that connect them. It is the absence of these connecting hand grip bars and the great distance they create between the straight horizontal parallel bars that makes this ergonomic exercise grip structure unique from any other single bar grip or Swiss bar structure in design, use and function.
These two straight horizontal parallel bars in the ergonomic exercise grip structure are separated by a short distance which only allows for a prone or supine grip.
This short distance prohibits a neutral grip as a trainee could not fit their hands in between the straight horizontal parallel bars in the neutral position as there is not enough space and there are also no neutral hand grip bars for them to engage.
Instead of neutral hand grip bars, these straight horizontal parallel bars are joined by short flat joining plates whose length and width enable them to serve only as a joining feature and not as a grip. These flat joining plates connect the straight horizontal parallel bars in the middle and have an eyelet in their center which enables a cable or machine attachment which gives the closely spaced straight horizontal parallel bars two identical lateral portions without any perpendicular or diagonal grip bars connecting them.
A trainee also cannot use a Swiss bar structure to perform barbell squats as the distance between the horizontal parallel bars is too great to safely place and balance it on their upper back. The joining neutral grip bars would also add further discomfort and instability making this application impractical and potentially dangerous.

The seated calf raise is performed when the trainee orients the bar so that it is perpendicular to their thighs and then places it across the front of their thighs just above the knee in the seated position.

This short distance prohibits a neutral grip as a trainee could not fit their hands in between the straight horizontal parallel bars in the neutral position as there is not enough space and there are also no neutral hand grip bars for them to engage.
Instead of neutral hand grip bars, these straight horizontal parallel bars are joined by short flat joining plates whose length and width enable them to serve only as a joining feature and not as a grip. These flat joining plates connect the straight horizontal parallel bars in the middle and have an eyelet in their center which enables a cable or machine attachment which gives the closely spaced straight horizontal parallel bars two identical lateral portions without any perpendicular or diagonal grip bars connecting them.
3 The flat joining plates may also be attached to the outside ends of the straight horizontal parallel bars and have 1 or 2 inch in diameter standard or Olympic style weight bearing rods attached to the center of their outside ends placed directly between the parallel bars.
This creates two identical lateral portions consisting of flat joining plates and weight bearing rods and a medial portion which consists of the straight horizontal parallel bars without any perpendicular or diagonal grip bars connecting them.
The center of gravity is placed directly between the straight horizontal parallel bars by the use of the centered eyelet on the flat joining plate or by weight bearing rods placed on the outside ends in the middle of these flat joining plates.
The short length and narrow width of the flat joining plates prevents them from being used as a grip like a Swiss bar as a trainee would be unable to hold them in the neutral grip manner. Instead, the short length of these flat joining plates separate the straight horizontal parallel bars by a short distance which serves to create a hand insertion space between them which houses the center of gravity while only allowing for a prone or supine grip.
This hand insertion space between the straight horizontal parallel bars enables a trainee to perform bicep curls, triceps extensions and straight arm pullovers with a prone or supine grip in an effective manner that eliminates the potential wrist strain of single bar structures while avoiding the dilutive mechanical leverage of Swiss Bar structures. This narrow hand insertion space houses the center of gravity provided by the eyelet in the centre of the flat joining plate or by the weight bearing rods placed in the centre of the outside ends of the flat joining plates.
Since the center of gravity is placed directly between the two straight horizontal parallel bars, the trainee can elect to grip either one of the parallel bars with their hands while allowing the second closer parallel bar to rest on a small portion of their forearms just below the wrist as a support which enables them to keep their wrists in a straight, neutral position while successfully engaging the targeted muscles to perform the exercise as the narrow distance between the straight horizontal parallel bars minimizes the use of mechanical leverage. Since the trainee can elect to use either straight horizontal parallel bar as a grip or as a support, the bars will be rubber coated or have removable foam sleeves to add comfort for both gripping and support. When engaged in this manner, the straight horizontal parallel bars are perpendicularly oriented with respect to the hands and forearms of the trainee.
This ergonomic exercise grip structure also provides a trainee with the option of using the traditional grip provided by single bar grip structures by gripping only one of the bars with their hands in the prone or supine position as well as the option of using the fat grip by gripping both bars in their hands in the prone or supine position.
When a trainee performs a barbell squat with the barbell embodiment of the ergonomic exercise grip structure, they will not have to choose between the high bar or low bar technique which places the barbell on their upper back above the spine of the scapula or below the spine of the scapula respectively. The ergonomic exercise grip structure described in this application provides a trainee with the best of both methods as both

Instead, the short length of these flat joining plates separate the straight horizontal parallel bars by a short distance which serves to create a hand insertion space between them which houses the center of gravity while only allowing for a prone or supine grip.
This hand insertion space between the straight horizontal parallel bars enables a trainee to perform bicep curls, triceps extensions and straight arm pullovers with a prone or supine grip in an effective manner that eliminates the potential wrist strain of single bar structures while avoiding the dilutive mechanical leverage of Swiss Bar structures. This narrow hand insertion space houses the center of gravity provided by the eyelet in the centre of the flat joining plate or by the weight bearing rods placed in the centre of the outside ends of the flat joining plates.
Since the center of gravity is placed directly between the two straight horizontal parallel bars, the trainee can elect to grip either one of the parallel bars with their hands while allowing the second closer parallel bar to rest on a small portion of their forearms just below the wrist as a support which enables them to keep their wrists in a straight, neutral position while successfully engaging the targeted muscles to perform the exercise as the narrow distance between the straight horizontal parallel bars minimizes the use of mechanical leverage.

When a trainee performs a barbell squat with the barbell embodiment of the ergonomic exercise grip structure, they will not have to choose between the high bar or low bar technique which places the barbell on their upper back above the spine of the scapula or below the spine of the scapula respectively. The ergonomic exercise grip structure described in this application provides a trainee with the best of both methods as both
4 horizontal parallel bars will more effectively rest on their upper back above and below the spine of the scapula. This will provide the trainee with better balance and thoracic stability making this exercise more effective and less risky.
The ergonomic exercise grip structure will also improve the seated calf raise exercise. It does so by the use of its narrowly spaced straight horizontal parallel bars which evenly distribute the weight between them which improves balance and safety while reducing strain on the trainee's thighs. The narrow distance between the parallel bars also reduces mechanical leverage while enhancing the stimulation of the targeted muscles.
The application of rubber grips or removable foam pads will also reduce discomfort for the trainee. When engaged in this manner, the straight horizontal parallel bars are perpendicularly oriented with respect to the thighs of the trainee when in the seated position and engage the front of the thighs at two points slightly above the knee.
This ergonomic exercise grip structure can be used in barbells, dumbbells, cable attachments, machine attachments and as a barbell with a cable attachment.
Although the straight horizontal parallel bars are identical in width, they do not have to be the same length in some embodiments of the ergonomic exercise grip structure.
The proposed ergonomic exercise grip structure is very versatile and enables the performance of several exercises in a safe productive manner.
B. Description of Prior Art As discussed below, no prior art discloses an ergonomic exercise grip structure that provides the benefits of straight bar and Swiss bar grip structures while compensating for their aforementioned deficiencies. There is no other grip structure that can be applied in multiple formats including, but not limited to barbells, dumbbells, cable attachments and machine attachments which enhances the performance and effectiveness of multiple exercises including but not limited to bicep curls, triceps extensions, straight arm pullovers, barbell squats and seated calf raises. The is no prior art that discloses a grip structure that provides a trainee with several prone and supine grip options such as the grip style described in this application in which the trainee engages one of the straight horizontal parallel bars with their hands while allowing the second closer parallel bar to rest on a small portion of their forearms just below the wrist, the upper back above and below the spine of the scapula, the front of the thighs just above the knee or with the hands in the standard and fat grips.
In US Patent 4,018,442 to Galler of April 1911'1977, discloses a free standing, quadrilateral like symmetrical frame in which the trainee stands inside the frame and lifts it by gripping the parallel side bars. Weight plates are attached to the frame through weight supporting rods that are attached to the centre of the side gripping bars. This invention is used to perform deadlifts and other movements with the trainee standing inside of it, but the front and back parallel support bars are too far apart to use it in the manner claimed in this application.
In US Patent 5,118,097 to Cousins of June 2nd 1992, discloses a parallel rotation bar that consists of parallel bars forming a rectangular frame for gymnastics exercises. The two main support bars are far enough apart for a person to fit between them and not close enough to be used as a weight training device as proposed by the ergonomic exercise grip structure.
In US Patent 4,312,506 to Brennan of November 5, 1979, discloses a device in the form of a barbell or dumbbell intended for performing bicep curl exercises consisting of a parallel grip bar and rectangular support plate which moves the centre of gravity rearwardly away from the hand while being used. The grip bar and support plate are distinct items and cannot be used interchangeably.
In US Provisional Patent Application No. 61/803,328 to Grace of March 19, 2013 discloses a barbell that consists of a plate accepting bar with at least one longitudinally extending fulcrum bar that is positioned to contact the trainee's forearm during a curl movement creating a lever arm through the handle. The centre of gravity, however, is online with the grip bar and not behind it as in the ergonomic exercise grip structure claimed in this application.
In US Patent 8,574,136 to Burstrom of November 5, 2013 discloses a barbell having a padded parallel engaging support bar as an accessary for use with a barbell which engages the forearm of an end user to minimize wrist strain during a curling exercise with a barbell. The parallel engaging bar is joined to the main barbell by a cross brace which is adjustable in some embodiments of the invention. However, this invention functions as a single bar structure as the source of resistance and center of gravity is housed in the main barbell where the weight plates are attached and to which the trainee engages with their hands. The parallel engaging support bar is a detachable accessory and is not designed to evenly share the resistance with the main barbell as the center of gravity in this invention starts in the main barbell and then moves between these two items during the curling exercise. Figure 5 (aka FIG. 5) in the Burstrom document depicts the centre of gravity and how it is concentrated in the main barbell as in a single bar grip structure while the "parallel forearm engaging bar" makes contact with the users forearm close to the elbow using dilutive mechanical leverage as in a Swiss bar structure and does not make contact with the trainee's forearm "just below the wrist" as in the ergonomic exercise grip structure of this application.
As the trainee raises the barbell, the center of gravity moves from the main barbell towards the parallel engaging bar and then back to the main barbell as the trainee lowers it. The resistance is not evenly distributed between the barbell and parallel engaging bar like the ergonomic exercise grip structure described in this application even though the trainee grips the bar in the supine position making contact with the hands and different portion of the forearms. The barbell and parallel engaging support bar are distinct elements which cannot be used interchangeably as a grip or as a support since the source of resistance is from the main barbell. This prevents it from functioning in the same manner as the ergonomic exercise grip structure in this application which houses the centre of gravity between the two straight horizontal parallel bars which enables either one to be used as a grip or as a support. This invention is silent with regards to enabling the performance of any exercise besides curls and also cannot be used to perform biceps curls, triceps extensions, straight arm pullovers, squats or seated calf raises in the same manner as the ergonomic exercise grip structure disclosed in this application as the barbell does not evenly balance the resistance with the parallel engaging bar as it still functions as a single bar structure that borrows some of the dilutive mechanical leverage that a Swiss bar structure provides. This invention is silent with regards to allowing for a prone grip.
The cross brace that joins the parallel engaging arm to the main barbell is silent with regards to an eyelet or any means that enables a cable attachment which could be used to apply resistance evenly between the main barbell and the parallel engaging bar. The aforementioned Figure 5 of the Burstrom document indicates that this "parallel engaging bar" is much longer than the flat joining plate(s) of the ergonomic exercise grip structure as it places this engaging bar low on the forearm towards the elbow while the short distance between the straight horizontal parallel bars of ergonomic exercise grip structure place the second support bar high on the forearms just below the wrist. Even if one were to adjust this cross brace to shorten the distance between the main weight bearing bar and the parallel engaging bar, it would still not function in the same manner as the ergonomic exercise grip structure due to the aforementioned center of gravity being concentrated in the main barbell as in a single bar structure.
In US Patent Application Publication (US 2003/0130096 Al) to LaCroce of July 10, 2003 describes a barbell apparatus made of a pair of hand gripping bars that enables the trainee to use several hand gripping positions in the "Thumbs up" position where the hands are vertical facing each other and not with the supine/prone hands in the up or down position as in this the ergonomic exercise grip structure described in this application. This device, that LaCroce describes, is based on the original Swiss bar design which is solely intended to be used with the vertical "Thumbs Up" grip with its vertical gripping bars set between longer parallel support bars. Although the centre of gravity appears to be placed between the two parallel supporting bars, the vertical grip, that the device forces the user to employ, places the centre of gravity solely in the users hands as if they we holding a standard barbell. A trainee would also not be able to use this device in the manner described in this application because the vertical grip bars would prevent them from gripping it in a prone or supine position as they would get in the way of the trainees fingers preventing them from using it in the manner described in this application.
In US Patents 4,756,526 and 4,880,229 to Broussard on Jun 3, 1985 and Mar. 31, respectively, describe an exercise device comprising a pair of weight plates which can be mounted for rotation on a lifting bar with the plates' centers of gravity below the lifting bar and a leverage control bar, coupled to the plates for rotation positioned to contact the trainees forearm during a portion of the curling movement, to exert a relatively constant resistance during the movement. The centre of gravity and source of tension is below the grip bar and the grip/leverage control bar only makes contact with the trainees forearm during a portion of the exercise while the ergonomic exercise grip structure described in this application applies the centre of gravity between the two bars throughout the entire exercise and not just portions of it.
In US Patent 5,637,064 to Olson and Towley on Oct- 13, 1995 describes an adjustable dumbbell that includes a main central handle which can be selectively connected to outer weights with four cross support bars. The trainees forearm may make contact with these support bars while exercising but the centre of gravity is applied in the centre to the main central handle into the trainees' hands and not behind them as in the ergonomic exercise grip structure described in this application.
In US Patent Application US 2016/0051857 Al to Rasner on Feb 25, 2016 describes a variable grip exercise bar based on the original Swiss bar design in which the trainee uses a vertical thumbs up position similar to LaCroce (US 2003/0130096 Al) except this invention has several pairs of vertical grips which connect the main horizontal parallel bars at both perpendicular and diagonal angles along with multiple ring based attachment means throughout the exercise bar to attach it to a cable system which provides for a variety of gripping positions. However, the vertical grip that the variable grip exercise bar forces the user to employ places the centre of gravity solely in the users hands as if they we holding a standard Swiss bar. A trainee would also not be able to use this variable grip exercise bar in the manner described by the ergonomic exercise grip structure because the distance between the main horizontal parallel bars in this invention is much wider than the distance between the two straight horizontal parallel bars in the ergonomic exercise grip structure proposed in this application. The two main horizontal parallel bars in this variable grip exercise bar are far enough apart for a person to fit their hands between them to engage the perpendicular or diagonal grip bars that connect them and not close enough to be used in the same manner proposed by the ergonomic exercise grip structure which does not have any of these intermediate grip bars and places the two straight horizontal parallel bars at a much closer distance which only allows for a prone or supine grip unlike the variable grip exercise bar which enables a multitude of grips.
If a trainee attempted to use this variable grip exercise bar in the manner described by the ergonomic exercise grip structure where the trainee engages one horizontal parallel bar with their hands while the second closer horizontal parallel bar rests on the forearms just below the wrist, the second closer horizontal bar would rest low on their forearms due to the larger distance between them which moves the center of gravity towards their elbows resulting in excess mechanical leverage. This mechanical leverage dilutes the effectiveness of the exercise and results in under stimulation of the targeted muscles while also being uncomfortable on the trainee's forearms rendering this technique impractical and ineffective even if the bars are padded.
This variable grip exercise bar has multiple attachment means via a ring on one of the intermediate grip bars and at other locations, including attachment means disposed on one or both of the horizontal bars. The ergonomic exercise grip structure has no intermediate grip bars and its flat join plate with an eyelet in its centre is too short and narrow to function as an intermediate grip and only serves as a joining feature while also serving as the only attachment means.
Some embodiments of the variable grip exercise bar claimed in this application have hinged joints for adjustment of the two lateral portions which lock the lateral portions of horizontal bars via locking mechanisms. The ergonomic exercise grip structure claimed in this application, specifically its straight horizontal parallel bars, do not have any hinges and are not adjustable in this manner.
The variable grip exercise bar is silent with regards to being used to perform seated calf raises and could not be used to perform them in the same manner as the ergonomic exercise grip structure as the distance between its horizontal parallel bars places the center of gravity further up the trainee's thighs towards their hips which over utilizes mechanical leverage and greatly reduces the effectiveness of the exercise. The neutral grip bars of this invention also reduce the effectiveness of this exercise because they would also make the exercise uncomfortable by pressing onto the thighs of the trainee.
In US Patent Application US 8,951,170 B1 to Tayo on Feb 10, 2015 describes a barbell having a plurality of differently oriented hand grips integrated therein and is composed of two generally parallel members defining a horizontal axis and in between a plurality of hand grips are provided at varying angles along a vertical axis. However, this invention is based on the Swiss bar design similar to Rasner (US 2016/0051857 Al) and LaCroce (US
2003/0130096 Al) except it is in a barbell format and not a cable attachment.
It also has multiple vertical grips, but unlike Rasner and LaCroce, these grips are adjustable and can move along tracks built into the main parallel bars. Just as with Rasner and LaCroce, the vertical grip that the Tayo device forces the user to employ places the centre of gravity solely in the user's hands. The two main horizontal parallel bars in this invention are spaced far enough apart for a person to fit their hands in between them to engage the perpendicular or diagonal grip bars that connect them and not close enough to be used in the same manner proposed by the ergonomic exercise grip structure which does not have any of these intermediate grips and places the two horizontal parallel bars at a much closer distance which only allows for a prone or supine grip.
A trainee would also not be able to use this device in the manner claimed by the ergonomic exercise grip structure because the vertical grip bars would prevent a prone or supine hand grip as they would get in the way of the trainees fingers. Although this invention has plate loading rods similar to some embodiments of the ergonomic exercise grip structure proposed in this application, its grip structure is fundamentally different and applies the resistance from these weight bearing rods in a different manner. This device only allows a trainee to use a thumbs up palms facing each other grip while the ergonomic exercise grip structure described in this application uses a supine or prone palms up or down grip. The two main parallel support bars are far enough apart for a person to fit their hands in between them with the plurality of perpendicular and diagonal grips and not close enough to be used in the manner proposed by the ergonomic exercise grip structure.
This invention is silent regarding the use of the main parallel bars as a supine or prone grip in the manner described by the ergonomic exercise grip structure in this application.
If a trainee attempted to use this invention in the manner described by the ergonomic exercise grip structure where the trainee engages one horizontal parallel bar with their hands while the second closer horizontal parallel bar rests on the forearms just below the wrists, the second closer horizontal bar would rest lower on their forearms well below the wrist due to the distance between the bars which moves the center of gravity towards their elbows resulting in excess mechanical leverage. This mechanical leverage dilutes the effectiveness of the exercise and results in under stimulation of the targeted muscles while also being uncomfortable on the trainee's forearms rendering this technique impractical and ineffective even if the bars are padded. This barbell having a plurality of differently oriented hand grips integrated therein is silent with regards to having any such padding on its horizontal parallel bars and is silent with regard to using these horizontal parallel bars as a grip or as a support.
This invention is silent with regards to being used to perform barbell squats and could not be used to perform them in the same manner as the ergonomic exercise grip structure as the distance between the horizontal parallel bars is too great to safely place and balance it on the upper back of a trainee. The joining neutral grip bars would also add further discomfort and instability making this application impractical and potentially dangerous.
This invention is silent with regards to being used to perform seated calf raises and could not be used to perform them in the same manner as the ergonomic exercise grip structure as the distance between the horizontal parallel bars places the center of gravity further up the trainee's thighs towards their hips which over utilizes mechanical leverage and greatly reduces the effectiveness of the exercise. The neutral grip bars of this invention also reduce the effectiveness of this exercise because they would also make the exercise uncomfortable by pressing onto the thighs of the trainee.
In EP 0 730886 Al to Sakai on February 27, 1996 describes a strength training appliance to ease stiffness in the joints of the human body. It consists of two pairs of parallel bars, one being longer than the other creating a rectangular shaped device intended to be made of wood. The user grips this device with their hands facing one another just as in Rasner (US 2016/0051857 Al), LaCroce (US 2003/0130096 Al) and Tayo (US 8,951,170 B1).
This device is not intended for weight training or any form of resistance based exercise as it is not designed to be attached to a cable pulley resistance system or to enable the attachment of weights. The resistance is provided by the users own body weight to perform radio gymnastic exercises to relieve parts of the body from fatigue resulting from physical labor or strenuous exercise and not to be gripped and used in the manner described in this application.
US8172731B1A to Bredda on July 14, 2010 describes a gridiron power machine system for providing users with a large number of lifting exercises which consists of a support assembly that has laterally spaced horizontal base rails which enables the safe performance of a number of exercises including squats and standing calf raises. However, this machine engages the user with a single cross bar similar to a single bar structure except weight plates are not attached to it. Instead, this cross bar is attached to adjustable pivot rails to which weight bearing rods are attached This cross bar does not engage the upper back of the trainee above and below the spine of the scapula as it consists of a single bar.
While the above-described devices fulfill their respective and particular objects and requirements, they do not describe an ergonomic exercise grip structure that provides the benefits of straight bar and Swiss bar grip structures while compensating for their aforementioned deficiencies that can be applied in multiple formats including, but not limited to barbells, dumbbells, cable attachments and machine attachments which enhance the performance and effectiveness of multiple exercises including but not limited to bicep curls, triceps extensions, straight arm pullovers, barbell squats and seated calf raises while providing the trainee with several prone and supine grip options such as the grip style described in this application in which the trainee engages one of the straight horizontal parallel bars with their hands while allowing the second closer straight horizontal parallel bar to rest on a small portion of their forearms just below the wrist, the upper back above and below the spine of the scapula, the front of the thighs just above the knee or with the hands in the standard and fat grips. In this regard, the ergonomic exercise grip structure departs from the conventional concepts and designs of the prior art.
Summary Of The Invention Briefly, the present invention comprises of a set of closely spaced straight horizontal parallel bars joined in the center, at the ends, or both by a flat joining plate or plates that have an eyelet or weight bearing rods in their centre which serve as the center of gravity and evenly distribute the resistance between the two straight horizontal parallel bars. This enables a trainee to use either straight horizontal parallel bar interchangeably as a grip or as a support. The straight horizontal parallel bars are spaced closely together because they are not connected by any neutral grip bars. Instead of neutral grip bars, the straight horizontal parallel bars are joined by the flat joining plates which are too short and narrow to be used as grips. As a result, the two straight horizontal parallel bars are free of any intermediate joining grips which creates a narrow hand insertion space between them which houses the center of gravity. This enables the trainee to use a prone or supine grip where one bar engages the hands, while the second closer bar engages the forearms just below the wrist due to the short distance between them which enables the trainee to perform various exercises while keeping their wrists in a straight neutral position which eliminates the potential wrist strain of single bar structures while minimizing the dilutive mechanical leverage of Swiss bar structures. This same structure also enables the performance of barbell squats where both straight horizontal parallel bars engage the upper back of the trainee with one bar above and one bar below the spine of the scapula which provides the trainee with better thoracic stability. This structure may also be applied to the seated calf raise exercise where the straight horizontal parallel bars rest on the top of the thighs of the trainee just above the knee. This ergonomic exercise grip structure can be used to perform a number of exercises including but not limited to: Bicep curls, triceps extensions and press downs, pullovers, presses, rows, squats, seated calf raises, seated dorsiflexion, forearm flexion and extension. This ergonomic exercise grip structure can be applied to barbells, dumbbells, cable attachments and machine attachments and enables the user to perform exercises with several prone and supine grips.
Brief Description Of The Drawings The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention and together with the description serve to explain the principles of the invention.
The accompanying drawings display the invention in several forms. In such drawings:
FIG. 1 is a view of the ergonomic exercise grip structure as a closed end cable attachment that can be attached to a cable pulley machine, to a stationary bicep curl or triceps extension machine or to free weight plates through a cable or hook attached to the eyelet in the centre of a joining plate that is positioned between the two straight horizontal parallel bars of the ergonomic exercise grip structure.
FIG. 2 is a view of the ergonomic exercise grip structure as an open ended set of straight horizontal parallel bars joined in the middle by a plate which contains an eyelet in its centre which enables it to be attached to a cable pulley machine, to stationary biceps curl or triceps extension machines or to free weight plates through the use of a cable or hook.
This embodiment does not have a second set of joining plates as the cable attachment plate that joins the two straight horizontal parallel bars in the center performs this function and uses less material.
FIG. 3 is a view of the ergonomic exercise grip structure applied to a barbell where the source of tension is applied between the two straight horizontal parallel bars from the external plate loading rods which are attached mid-way between the two identical straight horizontal parallel bars by joining plates.
FIG. 4 is a view of the ergonomic exercise grip structure in barbell format as in FIG. 3 except this embodiment has an additional cable attachment that is used in the embodiment's displayed in FIG. 1 and FIG. 2. This format of the ergonomic exercise grip structure enables the trainee to perform exercises using resistance from cable pulley systems or free weight plates.
FIG. 5 is a view of the ergonomic exercise grip structure in a dumbbell format where the source of tension is applied between the two straight horizontal parallel bars from the external plate loading rods which are attached mid-way between the ends of the two straight horizontal parallel bars by a joining plate. The trainee, however, will need a pair of these ergonomic exercise grip structures to form a pair of dumbbells in order to perform exercises although some exercises can be performed with only one dumbbell at a time.
FIG. 6 is a view of the ergonomic exercise grip structure applied in a pull-down bar format where one of the straight horizontal parallel bars is much longer than the other. This enables the trainee to perform wide grip pulldown exercises in addition to the exercises that can be performed in the other embodiments of the ergonomic exercise grip structure.
FIG.7 is a series of photographs of the three grips that the ergonomic exercise grip structure allows:
Figure 7A depicts the preferred supine grip with the grip bar resting on the hands and support bar resting on the forearms just below the wrists.
Figure 7B depicts the traditional supine grip with only one bar being held by the hands.
Figure 7C depicts the fat bar supine grip with both bars being held by the hands.
Description Of The Preferred Embodiment The following detailed description is merely exemplary in nature and is not intended to limit the described embodiments of the application and uses of the described embodiments. As used herein, the word "exemplary" or "illustrative" means "serving as an example, instance, or illustration." Any implementation described herein as "exemplary" or "illustrative" is not necessarily to be construed as preferred or advantageous over other implementations. All of the implementations described below are exemplary implementations provided to enable persons skilled in the art to practice the disclosure and are not intended to limit the scope of the appended claims. Furthermore, there is no intention to be bound by any expressed or implied theory presented in the preceding field of the invention, background, brief summary or the following detailed description.
Detailed reference will now be made to the preferred embodiment of the present invention, examples of which are illustrated in figures 1-7. An ergonomic exercise grip structure and method of use that can be applied to barbells, dumbbells, cable attachments and exercise machines where the straight horizontal parallel bars 1 function interchangeably as a grip or as a support and evenly share the weight between them instead of exclusively within the hand grip as in standard barbells, Swiss bars, dumbbells, cables and machine attachments.
This is accomplished by the use of two straight horizontal parallel bars 1 that are connected at the centre (FIG. 1, 2, 6 & 7) or at the ends (FIG. 3, 4 & 5) by joining plates 2.
Since the straight horizontal parallel bars 1 are identical in width and equally share the resistance between them, the trainee can use either bar as a grip or as a support. With the furthest away grip bar being held by the hands with the closer support bar resting on the trainees forearms just below the wrist, the trainee's wrists will be locked so that they cannot flex or extend them which reduces wrist strain as the centre of gravity (Primary source of tension) is no longer exclusively on their hands but shared between the bars.
This also enables the trainee to apply more tension to the targeted muscles since they don't need to focus on keeping their wrists straight as the ergonomic exercise grip structure automatically does this for them (FIG. 7A).
These straight horizontal parallel bars 1 can be rubber coated or have removable foam sleeves to add comfort for both gripping and support and can be used to perform several exercises for the arms, torso and lower body.
In the case of cable attachments or machines, the centre of gravity is applied directly between the two straight horizontal parallel bars 1 by the application of a joining plate 2 with an eyelet in its centre 4 placed directly between the two straight horizontal parallel bars 1 as seen in FIG. 1, 2, 4, 6 &7.
In the case of barbells and dumbbells, weight supporting rods 3 attached to the ends of the ergonomic exercise grip structure mid-way between the two straight horizontal parallel bars 1 by joining plates 2 keep the centre of gravity between the two straight horizontal parallel bars 1 as seen in FIG. 3, 4 & 5. These weight bearing rods 3 can be 1 inch in diameter in order to accommodate standard weight plates or 2 inches in diameter to accommodate Olympic plates.
It is also possible to have a barbell with the 1 or 2 inch in diameter weight bearing rods 3 with a joining plate 2 with an eyelet in its centre 4 between the two straight horizontal parallel bars 1 giving the trainee the option to use weight plate resistance, cable resistance or both.
While the invention has been described in several embodiments, it is to be understood by those skilled in the art that the invention is not limited thereto and the scope should be interpreted in conjunction with the appended claims.
The ergonomic exercise grip structure will also improve the seated calf raise exercise. It does so by the use of its narrowly spaced straight horizontal parallel bars which evenly distribute the weight between them which improves balance and safety while reducing strain on the trainee's thighs. The narrow distance between the parallel bars also reduces mechanical leverage while enhancing the stimulation of the targeted muscles.
The application of rubber grips or removable foam pads will also reduce discomfort for the trainee. When engaged in this manner, the straight horizontal parallel bars are perpendicularly oriented with respect to the thighs of the trainee when in the seated position and engage the front of the thighs at two points slightly above the knee.
This ergonomic exercise grip structure can be used in barbells, dumbbells, cable attachments, machine attachments and as a barbell with a cable attachment.
Although the straight horizontal parallel bars are identical in width, they do not have to be the same length in some embodiments of the ergonomic exercise grip structure.
The proposed ergonomic exercise grip structure is very versatile and enables the performance of several exercises in a safe productive manner.
B. Description of Prior Art As discussed below, no prior art discloses an ergonomic exercise grip structure that provides the benefits of straight bar and Swiss bar grip structures while compensating for their aforementioned deficiencies. There is no other grip structure that can be applied in multiple formats including, but not limited to barbells, dumbbells, cable attachments and machine attachments which enhances the performance and effectiveness of multiple exercises including but not limited to bicep curls, triceps extensions, straight arm pullovers, barbell squats and seated calf raises. The is no prior art that discloses a grip structure that provides a trainee with several prone and supine grip options such as the grip style described in this application in which the trainee engages one of the straight horizontal parallel bars with their hands while allowing the second closer parallel bar to rest on a small portion of their forearms just below the wrist, the upper back above and below the spine of the scapula, the front of the thighs just above the knee or with the hands in the standard and fat grips.
In US Patent 4,018,442 to Galler of April 1911'1977, discloses a free standing, quadrilateral like symmetrical frame in which the trainee stands inside the frame and lifts it by gripping the parallel side bars. Weight plates are attached to the frame through weight supporting rods that are attached to the centre of the side gripping bars. This invention is used to perform deadlifts and other movements with the trainee standing inside of it, but the front and back parallel support bars are too far apart to use it in the manner claimed in this application.
In US Patent 5,118,097 to Cousins of June 2nd 1992, discloses a parallel rotation bar that consists of parallel bars forming a rectangular frame for gymnastics exercises. The two main support bars are far enough apart for a person to fit between them and not close enough to be used as a weight training device as proposed by the ergonomic exercise grip structure.
In US Patent 4,312,506 to Brennan of November 5, 1979, discloses a device in the form of a barbell or dumbbell intended for performing bicep curl exercises consisting of a parallel grip bar and rectangular support plate which moves the centre of gravity rearwardly away from the hand while being used. The grip bar and support plate are distinct items and cannot be used interchangeably.
In US Provisional Patent Application No. 61/803,328 to Grace of March 19, 2013 discloses a barbell that consists of a plate accepting bar with at least one longitudinally extending fulcrum bar that is positioned to contact the trainee's forearm during a curl movement creating a lever arm through the handle. The centre of gravity, however, is online with the grip bar and not behind it as in the ergonomic exercise grip structure claimed in this application.
In US Patent 8,574,136 to Burstrom of November 5, 2013 discloses a barbell having a padded parallel engaging support bar as an accessary for use with a barbell which engages the forearm of an end user to minimize wrist strain during a curling exercise with a barbell. The parallel engaging bar is joined to the main barbell by a cross brace which is adjustable in some embodiments of the invention. However, this invention functions as a single bar structure as the source of resistance and center of gravity is housed in the main barbell where the weight plates are attached and to which the trainee engages with their hands. The parallel engaging support bar is a detachable accessory and is not designed to evenly share the resistance with the main barbell as the center of gravity in this invention starts in the main barbell and then moves between these two items during the curling exercise. Figure 5 (aka FIG. 5) in the Burstrom document depicts the centre of gravity and how it is concentrated in the main barbell as in a single bar grip structure while the "parallel forearm engaging bar" makes contact with the users forearm close to the elbow using dilutive mechanical leverage as in a Swiss bar structure and does not make contact with the trainee's forearm "just below the wrist" as in the ergonomic exercise grip structure of this application.
As the trainee raises the barbell, the center of gravity moves from the main barbell towards the parallel engaging bar and then back to the main barbell as the trainee lowers it. The resistance is not evenly distributed between the barbell and parallel engaging bar like the ergonomic exercise grip structure described in this application even though the trainee grips the bar in the supine position making contact with the hands and different portion of the forearms. The barbell and parallel engaging support bar are distinct elements which cannot be used interchangeably as a grip or as a support since the source of resistance is from the main barbell. This prevents it from functioning in the same manner as the ergonomic exercise grip structure in this application which houses the centre of gravity between the two straight horizontal parallel bars which enables either one to be used as a grip or as a support. This invention is silent with regards to enabling the performance of any exercise besides curls and also cannot be used to perform biceps curls, triceps extensions, straight arm pullovers, squats or seated calf raises in the same manner as the ergonomic exercise grip structure disclosed in this application as the barbell does not evenly balance the resistance with the parallel engaging bar as it still functions as a single bar structure that borrows some of the dilutive mechanical leverage that a Swiss bar structure provides. This invention is silent with regards to allowing for a prone grip.
The cross brace that joins the parallel engaging arm to the main barbell is silent with regards to an eyelet or any means that enables a cable attachment which could be used to apply resistance evenly between the main barbell and the parallel engaging bar. The aforementioned Figure 5 of the Burstrom document indicates that this "parallel engaging bar" is much longer than the flat joining plate(s) of the ergonomic exercise grip structure as it places this engaging bar low on the forearm towards the elbow while the short distance between the straight horizontal parallel bars of ergonomic exercise grip structure place the second support bar high on the forearms just below the wrist. Even if one were to adjust this cross brace to shorten the distance between the main weight bearing bar and the parallel engaging bar, it would still not function in the same manner as the ergonomic exercise grip structure due to the aforementioned center of gravity being concentrated in the main barbell as in a single bar structure.
In US Patent Application Publication (US 2003/0130096 Al) to LaCroce of July 10, 2003 describes a barbell apparatus made of a pair of hand gripping bars that enables the trainee to use several hand gripping positions in the "Thumbs up" position where the hands are vertical facing each other and not with the supine/prone hands in the up or down position as in this the ergonomic exercise grip structure described in this application. This device, that LaCroce describes, is based on the original Swiss bar design which is solely intended to be used with the vertical "Thumbs Up" grip with its vertical gripping bars set between longer parallel support bars. Although the centre of gravity appears to be placed between the two parallel supporting bars, the vertical grip, that the device forces the user to employ, places the centre of gravity solely in the users hands as if they we holding a standard barbell. A trainee would also not be able to use this device in the manner described in this application because the vertical grip bars would prevent them from gripping it in a prone or supine position as they would get in the way of the trainees fingers preventing them from using it in the manner described in this application.
In US Patents 4,756,526 and 4,880,229 to Broussard on Jun 3, 1985 and Mar. 31, respectively, describe an exercise device comprising a pair of weight plates which can be mounted for rotation on a lifting bar with the plates' centers of gravity below the lifting bar and a leverage control bar, coupled to the plates for rotation positioned to contact the trainees forearm during a portion of the curling movement, to exert a relatively constant resistance during the movement. The centre of gravity and source of tension is below the grip bar and the grip/leverage control bar only makes contact with the trainees forearm during a portion of the exercise while the ergonomic exercise grip structure described in this application applies the centre of gravity between the two bars throughout the entire exercise and not just portions of it.
In US Patent 5,637,064 to Olson and Towley on Oct- 13, 1995 describes an adjustable dumbbell that includes a main central handle which can be selectively connected to outer weights with four cross support bars. The trainees forearm may make contact with these support bars while exercising but the centre of gravity is applied in the centre to the main central handle into the trainees' hands and not behind them as in the ergonomic exercise grip structure described in this application.
In US Patent Application US 2016/0051857 Al to Rasner on Feb 25, 2016 describes a variable grip exercise bar based on the original Swiss bar design in which the trainee uses a vertical thumbs up position similar to LaCroce (US 2003/0130096 Al) except this invention has several pairs of vertical grips which connect the main horizontal parallel bars at both perpendicular and diagonal angles along with multiple ring based attachment means throughout the exercise bar to attach it to a cable system which provides for a variety of gripping positions. However, the vertical grip that the variable grip exercise bar forces the user to employ places the centre of gravity solely in the users hands as if they we holding a standard Swiss bar. A trainee would also not be able to use this variable grip exercise bar in the manner described by the ergonomic exercise grip structure because the distance between the main horizontal parallel bars in this invention is much wider than the distance between the two straight horizontal parallel bars in the ergonomic exercise grip structure proposed in this application. The two main horizontal parallel bars in this variable grip exercise bar are far enough apart for a person to fit their hands between them to engage the perpendicular or diagonal grip bars that connect them and not close enough to be used in the same manner proposed by the ergonomic exercise grip structure which does not have any of these intermediate grip bars and places the two straight horizontal parallel bars at a much closer distance which only allows for a prone or supine grip unlike the variable grip exercise bar which enables a multitude of grips.
If a trainee attempted to use this variable grip exercise bar in the manner described by the ergonomic exercise grip structure where the trainee engages one horizontal parallel bar with their hands while the second closer horizontal parallel bar rests on the forearms just below the wrist, the second closer horizontal bar would rest low on their forearms due to the larger distance between them which moves the center of gravity towards their elbows resulting in excess mechanical leverage. This mechanical leverage dilutes the effectiveness of the exercise and results in under stimulation of the targeted muscles while also being uncomfortable on the trainee's forearms rendering this technique impractical and ineffective even if the bars are padded.
This variable grip exercise bar has multiple attachment means via a ring on one of the intermediate grip bars and at other locations, including attachment means disposed on one or both of the horizontal bars. The ergonomic exercise grip structure has no intermediate grip bars and its flat join plate with an eyelet in its centre is too short and narrow to function as an intermediate grip and only serves as a joining feature while also serving as the only attachment means.
Some embodiments of the variable grip exercise bar claimed in this application have hinged joints for adjustment of the two lateral portions which lock the lateral portions of horizontal bars via locking mechanisms. The ergonomic exercise grip structure claimed in this application, specifically its straight horizontal parallel bars, do not have any hinges and are not adjustable in this manner.
The variable grip exercise bar is silent with regards to being used to perform seated calf raises and could not be used to perform them in the same manner as the ergonomic exercise grip structure as the distance between its horizontal parallel bars places the center of gravity further up the trainee's thighs towards their hips which over utilizes mechanical leverage and greatly reduces the effectiveness of the exercise. The neutral grip bars of this invention also reduce the effectiveness of this exercise because they would also make the exercise uncomfortable by pressing onto the thighs of the trainee.
In US Patent Application US 8,951,170 B1 to Tayo on Feb 10, 2015 describes a barbell having a plurality of differently oriented hand grips integrated therein and is composed of two generally parallel members defining a horizontal axis and in between a plurality of hand grips are provided at varying angles along a vertical axis. However, this invention is based on the Swiss bar design similar to Rasner (US 2016/0051857 Al) and LaCroce (US
2003/0130096 Al) except it is in a barbell format and not a cable attachment.
It also has multiple vertical grips, but unlike Rasner and LaCroce, these grips are adjustable and can move along tracks built into the main parallel bars. Just as with Rasner and LaCroce, the vertical grip that the Tayo device forces the user to employ places the centre of gravity solely in the user's hands. The two main horizontal parallel bars in this invention are spaced far enough apart for a person to fit their hands in between them to engage the perpendicular or diagonal grip bars that connect them and not close enough to be used in the same manner proposed by the ergonomic exercise grip structure which does not have any of these intermediate grips and places the two horizontal parallel bars at a much closer distance which only allows for a prone or supine grip.
A trainee would also not be able to use this device in the manner claimed by the ergonomic exercise grip structure because the vertical grip bars would prevent a prone or supine hand grip as they would get in the way of the trainees fingers. Although this invention has plate loading rods similar to some embodiments of the ergonomic exercise grip structure proposed in this application, its grip structure is fundamentally different and applies the resistance from these weight bearing rods in a different manner. This device only allows a trainee to use a thumbs up palms facing each other grip while the ergonomic exercise grip structure described in this application uses a supine or prone palms up or down grip. The two main parallel support bars are far enough apart for a person to fit their hands in between them with the plurality of perpendicular and diagonal grips and not close enough to be used in the manner proposed by the ergonomic exercise grip structure.
This invention is silent regarding the use of the main parallel bars as a supine or prone grip in the manner described by the ergonomic exercise grip structure in this application.
If a trainee attempted to use this invention in the manner described by the ergonomic exercise grip structure where the trainee engages one horizontal parallel bar with their hands while the second closer horizontal parallel bar rests on the forearms just below the wrists, the second closer horizontal bar would rest lower on their forearms well below the wrist due to the distance between the bars which moves the center of gravity towards their elbows resulting in excess mechanical leverage. This mechanical leverage dilutes the effectiveness of the exercise and results in under stimulation of the targeted muscles while also being uncomfortable on the trainee's forearms rendering this technique impractical and ineffective even if the bars are padded. This barbell having a plurality of differently oriented hand grips integrated therein is silent with regards to having any such padding on its horizontal parallel bars and is silent with regard to using these horizontal parallel bars as a grip or as a support.
This invention is silent with regards to being used to perform barbell squats and could not be used to perform them in the same manner as the ergonomic exercise grip structure as the distance between the horizontal parallel bars is too great to safely place and balance it on the upper back of a trainee. The joining neutral grip bars would also add further discomfort and instability making this application impractical and potentially dangerous.
This invention is silent with regards to being used to perform seated calf raises and could not be used to perform them in the same manner as the ergonomic exercise grip structure as the distance between the horizontal parallel bars places the center of gravity further up the trainee's thighs towards their hips which over utilizes mechanical leverage and greatly reduces the effectiveness of the exercise. The neutral grip bars of this invention also reduce the effectiveness of this exercise because they would also make the exercise uncomfortable by pressing onto the thighs of the trainee.
In EP 0 730886 Al to Sakai on February 27, 1996 describes a strength training appliance to ease stiffness in the joints of the human body. It consists of two pairs of parallel bars, one being longer than the other creating a rectangular shaped device intended to be made of wood. The user grips this device with their hands facing one another just as in Rasner (US 2016/0051857 Al), LaCroce (US 2003/0130096 Al) and Tayo (US 8,951,170 B1).
This device is not intended for weight training or any form of resistance based exercise as it is not designed to be attached to a cable pulley resistance system or to enable the attachment of weights. The resistance is provided by the users own body weight to perform radio gymnastic exercises to relieve parts of the body from fatigue resulting from physical labor or strenuous exercise and not to be gripped and used in the manner described in this application.
US8172731B1A to Bredda on July 14, 2010 describes a gridiron power machine system for providing users with a large number of lifting exercises which consists of a support assembly that has laterally spaced horizontal base rails which enables the safe performance of a number of exercises including squats and standing calf raises. However, this machine engages the user with a single cross bar similar to a single bar structure except weight plates are not attached to it. Instead, this cross bar is attached to adjustable pivot rails to which weight bearing rods are attached This cross bar does not engage the upper back of the trainee above and below the spine of the scapula as it consists of a single bar.
While the above-described devices fulfill their respective and particular objects and requirements, they do not describe an ergonomic exercise grip structure that provides the benefits of straight bar and Swiss bar grip structures while compensating for their aforementioned deficiencies that can be applied in multiple formats including, but not limited to barbells, dumbbells, cable attachments and machine attachments which enhance the performance and effectiveness of multiple exercises including but not limited to bicep curls, triceps extensions, straight arm pullovers, barbell squats and seated calf raises while providing the trainee with several prone and supine grip options such as the grip style described in this application in which the trainee engages one of the straight horizontal parallel bars with their hands while allowing the second closer straight horizontal parallel bar to rest on a small portion of their forearms just below the wrist, the upper back above and below the spine of the scapula, the front of the thighs just above the knee or with the hands in the standard and fat grips. In this regard, the ergonomic exercise grip structure departs from the conventional concepts and designs of the prior art.
Summary Of The Invention Briefly, the present invention comprises of a set of closely spaced straight horizontal parallel bars joined in the center, at the ends, or both by a flat joining plate or plates that have an eyelet or weight bearing rods in their centre which serve as the center of gravity and evenly distribute the resistance between the two straight horizontal parallel bars. This enables a trainee to use either straight horizontal parallel bar interchangeably as a grip or as a support. The straight horizontal parallel bars are spaced closely together because they are not connected by any neutral grip bars. Instead of neutral grip bars, the straight horizontal parallel bars are joined by the flat joining plates which are too short and narrow to be used as grips. As a result, the two straight horizontal parallel bars are free of any intermediate joining grips which creates a narrow hand insertion space between them which houses the center of gravity. This enables the trainee to use a prone or supine grip where one bar engages the hands, while the second closer bar engages the forearms just below the wrist due to the short distance between them which enables the trainee to perform various exercises while keeping their wrists in a straight neutral position which eliminates the potential wrist strain of single bar structures while minimizing the dilutive mechanical leverage of Swiss bar structures. This same structure also enables the performance of barbell squats where both straight horizontal parallel bars engage the upper back of the trainee with one bar above and one bar below the spine of the scapula which provides the trainee with better thoracic stability. This structure may also be applied to the seated calf raise exercise where the straight horizontal parallel bars rest on the top of the thighs of the trainee just above the knee. This ergonomic exercise grip structure can be used to perform a number of exercises including but not limited to: Bicep curls, triceps extensions and press downs, pullovers, presses, rows, squats, seated calf raises, seated dorsiflexion, forearm flexion and extension. This ergonomic exercise grip structure can be applied to barbells, dumbbells, cable attachments and machine attachments and enables the user to perform exercises with several prone and supine grips.
Brief Description Of The Drawings The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention and together with the description serve to explain the principles of the invention.
The accompanying drawings display the invention in several forms. In such drawings:
FIG. 1 is a view of the ergonomic exercise grip structure as a closed end cable attachment that can be attached to a cable pulley machine, to a stationary bicep curl or triceps extension machine or to free weight plates through a cable or hook attached to the eyelet in the centre of a joining plate that is positioned between the two straight horizontal parallel bars of the ergonomic exercise grip structure.
FIG. 2 is a view of the ergonomic exercise grip structure as an open ended set of straight horizontal parallel bars joined in the middle by a plate which contains an eyelet in its centre which enables it to be attached to a cable pulley machine, to stationary biceps curl or triceps extension machines or to free weight plates through the use of a cable or hook.
This embodiment does not have a second set of joining plates as the cable attachment plate that joins the two straight horizontal parallel bars in the center performs this function and uses less material.
FIG. 3 is a view of the ergonomic exercise grip structure applied to a barbell where the source of tension is applied between the two straight horizontal parallel bars from the external plate loading rods which are attached mid-way between the two identical straight horizontal parallel bars by joining plates.
FIG. 4 is a view of the ergonomic exercise grip structure in barbell format as in FIG. 3 except this embodiment has an additional cable attachment that is used in the embodiment's displayed in FIG. 1 and FIG. 2. This format of the ergonomic exercise grip structure enables the trainee to perform exercises using resistance from cable pulley systems or free weight plates.
FIG. 5 is a view of the ergonomic exercise grip structure in a dumbbell format where the source of tension is applied between the two straight horizontal parallel bars from the external plate loading rods which are attached mid-way between the ends of the two straight horizontal parallel bars by a joining plate. The trainee, however, will need a pair of these ergonomic exercise grip structures to form a pair of dumbbells in order to perform exercises although some exercises can be performed with only one dumbbell at a time.
FIG. 6 is a view of the ergonomic exercise grip structure applied in a pull-down bar format where one of the straight horizontal parallel bars is much longer than the other. This enables the trainee to perform wide grip pulldown exercises in addition to the exercises that can be performed in the other embodiments of the ergonomic exercise grip structure.
FIG.7 is a series of photographs of the three grips that the ergonomic exercise grip structure allows:
Figure 7A depicts the preferred supine grip with the grip bar resting on the hands and support bar resting on the forearms just below the wrists.
Figure 7B depicts the traditional supine grip with only one bar being held by the hands.
Figure 7C depicts the fat bar supine grip with both bars being held by the hands.
Description Of The Preferred Embodiment The following detailed description is merely exemplary in nature and is not intended to limit the described embodiments of the application and uses of the described embodiments. As used herein, the word "exemplary" or "illustrative" means "serving as an example, instance, or illustration." Any implementation described herein as "exemplary" or "illustrative" is not necessarily to be construed as preferred or advantageous over other implementations. All of the implementations described below are exemplary implementations provided to enable persons skilled in the art to practice the disclosure and are not intended to limit the scope of the appended claims. Furthermore, there is no intention to be bound by any expressed or implied theory presented in the preceding field of the invention, background, brief summary or the following detailed description.
Detailed reference will now be made to the preferred embodiment of the present invention, examples of which are illustrated in figures 1-7. An ergonomic exercise grip structure and method of use that can be applied to barbells, dumbbells, cable attachments and exercise machines where the straight horizontal parallel bars 1 function interchangeably as a grip or as a support and evenly share the weight between them instead of exclusively within the hand grip as in standard barbells, Swiss bars, dumbbells, cables and machine attachments.
This is accomplished by the use of two straight horizontal parallel bars 1 that are connected at the centre (FIG. 1, 2, 6 & 7) or at the ends (FIG. 3, 4 & 5) by joining plates 2.
Since the straight horizontal parallel bars 1 are identical in width and equally share the resistance between them, the trainee can use either bar as a grip or as a support. With the furthest away grip bar being held by the hands with the closer support bar resting on the trainees forearms just below the wrist, the trainee's wrists will be locked so that they cannot flex or extend them which reduces wrist strain as the centre of gravity (Primary source of tension) is no longer exclusively on their hands but shared between the bars.
This also enables the trainee to apply more tension to the targeted muscles since they don't need to focus on keeping their wrists straight as the ergonomic exercise grip structure automatically does this for them (FIG. 7A).
These straight horizontal parallel bars 1 can be rubber coated or have removable foam sleeves to add comfort for both gripping and support and can be used to perform several exercises for the arms, torso and lower body.
In the case of cable attachments or machines, the centre of gravity is applied directly between the two straight horizontal parallel bars 1 by the application of a joining plate 2 with an eyelet in its centre 4 placed directly between the two straight horizontal parallel bars 1 as seen in FIG. 1, 2, 4, 6 &7.
In the case of barbells and dumbbells, weight supporting rods 3 attached to the ends of the ergonomic exercise grip structure mid-way between the two straight horizontal parallel bars 1 by joining plates 2 keep the centre of gravity between the two straight horizontal parallel bars 1 as seen in FIG. 3, 4 & 5. These weight bearing rods 3 can be 1 inch in diameter in order to accommodate standard weight plates or 2 inches in diameter to accommodate Olympic plates.
It is also possible to have a barbell with the 1 or 2 inch in diameter weight bearing rods 3 with a joining plate 2 with an eyelet in its centre 4 between the two straight horizontal parallel bars 1 giving the trainee the option to use weight plate resistance, cable resistance or both.
While the invention has been described in several embodiments, it is to be understood by those skilled in the art that the invention is not limited thereto and the scope should be interpreted in conjunction with the appended claims.
