(7) FIG. 7 illustrates two example barbell grips, in a fully closed and secured position, attached to a barbell shaft, according to an example embodiment of the present invention.

(8) Some example embodiments of the present disclosure provide accessory devices, e.g., barbell grips, for use with a standard barbell that allow for a neutral grip to be used in a bench press exercise. These accessory devices may be low cost. Unlike a Swiss bar (or other barbell with neutral grips, e.g., Football bar) bar, they may also be easily portable, so that a weightlifter can easily carry them with gym equipment while traveling. They are also generally compatible with standard rack, bar, and safeties.

(9) In addition to providing a neutral grip bench press, the example accessory devices may also allow for different focus on pectoral and triceps muscles when performing bench presses or modified bench presses. Further exercises may be performed with the device using a barbell a with neutral grip position, e.g., hammer curls, skullcrushers (a tricep extension exercise), overhead press (military press), and pullovers. Exercises similar to neutral grip dumbbell bench press may be performed, but with better control over loading conditions than when dumbbells are used.

(10) Using a standard bench press rather than dumbbells allows the exercise to easily start with the weights in the correct position, using standard weightlifting equipment. Moreover, greater weights can be employed when using the example device and a barbell, than are practical or safe with a dumbbell bench press.

(11) An example barbell grip described herein allows for bench pressing with a neutral grip using a standard barbell and bench press rack, squat rack, power-rack, power cage, flat/incline/decline bench or other barbell weightlifting station which is capable of being used as a bench platform. The example grip non-permanently attaches to a standard barbell. The example grips are intended to be used in pairs, and in some example embodiments they can be easily oriented parallel to each other when attached to the barbell, through the use of bubble level which may be included as part of the device.

(12) FIG. 1 illustrates an example barbell grip 100 in a closed position, according to an example embodiment of the present invention.

(13) A hinged, locking shaft collar 110 may be provided to attach the barbell grip to a barbell shaft. The shaft collar 110 may include two halves 112 and 114, which face each other in the closed configuration, and have an internal bore which mates with the barbell. It will be appreciated that the device does not need to be hinged and may instead be comprised of two or more separate elements which are joined/fastened together. While the illustrated shaft collar 110 is generally cylindrical on the outside, it should be appreciated that the outside shape of the shaft collar is usually irrelevant to the operation of the device, and may be round, square, or other convenient shape. This is in part because the loading of the shaft collar when in the barbell grip is in use is not rotational. Integral hinge elements 116 (not visible in this view) and 118 may be provided as part of shaft collar element 114 and integral hinge element 120 (not visible in this view) may be provided as part of shaft collar element 112. In the alternative, it may be appreciated that a non-integral hinge element could be coupled to the shaft collar using fasteners, welding, adhesives or other joining methods. A hinge pin 122 may be provided through the hinge elements, interconnecting them, so that the hinge elements can be pivoted about the hinge pin to open and/or close the shaft collar 110. Moreover, other sorts of securing approaches besides hinges may also be employed, provided that the device remains easy to attach to and remove from a barbell shaft, and the barbell grip is securely attached to remain in place during lifting exercises with typical loads.

(14) A flange or other protrusion, potentially with holes or slots, may extend from the two halves of the shaft collar 112 and 114. These flanges allow for a locking mechanism, such as the cam locks 124 and 126 to clamp the opposing halves 112 and 114 together. They may have other elements such as pins, hinges, etc. which enable closure mechanisms to swing/rotate to allow for easier opening or closing of the device. It may be appreciated that in place of a hinge another set of protrusions may replace them with the same design as their opposite.

(15) Alternatively, in place of or in addition to the cam locks 124 and 126, one or more other approaches to securing the shaft collar in a closed position on a barbell shaft may be employed, e.g. nuts and bolts, wing nuts, thumb screws, screws, draw latches, locking levers, etc. In place of the shaft collar 110, other approaches to attaching the grip to the barbell shaft may also be employed, such as a pipe clamp, o clamp, c clamp non permanent adhesive, friction fitting or other closure mechanism. A ratchet strap or tie down attachment, similar to the one used in the Croc Lock™ barbell collars from Elite FTS, in London, Ohio, may also be employed.

(16) A cantilever grip arm 140 may be attached to and extend from the shaft collar 110. The cantilever grip arm may preferably have a cylindrical shape and be knurled, coated or otherwise altered for better gripping. The cantilever grip arm 140 element may be, configured to be used in lifting the barbell by a weightlifter using a neutral grip when the shaft collar is attached to a conventional barbell shaft. The cantilever grip arm 140 can be coupled to the shaft collar 110 by any conventional approach, e.g., screw threads, press fit, welding, adhesives, or by being integrally formed as part of the attachment means, etc. It will be appreciated that cantilever grip arm 140 could also be coupled indirectly to the shaft collar, through some additional element, as long as the relative position of the grip and shaft collar were held in the same fixed relative position when the barbell grip 100 is used. As illustrated, the cantilever grip arm 140 may extend normally from the longitudinal axis of the bar when the attachment means is secured to the bar. In an alternative embodiment, the cantilever grip arm 140 may form a slightly acute angle with the longitudinal axis of the bar, while still being in the same plane as the bar. It may be appreciated that a pair of grips may be provided having opposite angles. Such a pair grips can then be employed to provide a user grip which is angled slightly inward or outward with respect to the midpoint of the bar, depending on the relative position of the pair of oppositely angled grips. In some alternatives, e.g., using multiple threaded receiving holes in the housing of the shaft collar and a threaded cantilever grip arm, multiple possible angles of attachment of the cantilever arm grip to the attachment means may be available using the same device.

(17) A brace arm 150 may also extend from the shaft collar 110. Preferably, the angle between the cantilever grip arm 140 and the brace arm 150 near wear they are coupled to the shaft collar 110 will be slightly less than a right angle, although it may also be at a right angle, or at a more acute angle. The brace arm 150 may preferably may be curved along its length and flared toward the outer end to allow for simpler manufacture, and to avoid the thumb when the user grips the cantilever grip element. It may also be appreciated that the flared configuration may reduce stress on the forearm by providing increased contact area for bracing when the barbell grip is in use. At the end opposite the shaft collar, the brace arm element 150 may have a flared portion 152, which conforms better against the arm of the user when the grip is used in a bench press. Preferably the brace arm 150 may have a slightly arcuate shape along its length, with the open curvature facing away from the cantilever grip arm 140. Optionally, padding or other components may be provided to allow better and more comfortable bracing. The brace arm 150 or may be coupled to the attachment means by any conventional approach, e.g., forming it as an integral part of one of the components of the shaft collar, screw threads, welding, adhesives, etc. It will be appreciated that brace arm 150 could also be coupled indirectly to the shaft collar, through some additional element, e.g., by being attached to the cantilever grip arm, as long as the brace arm, cantilever grip arm and shaft collar were held in the same relative position when the barbell grip was in use.

(18) In an alternative embodiment, the brace arm may be rod shaped along all or part of its length. In another alternative embodiment, arcuate arms may extend from the outer end of the brace arm, to form a C-shaped brace, preferably open toward the cantilever grip element.

(19) All of the elements of the barbell grip 100 may be formed from various materials with sufficient strength, e.g., steel (low, medium or high alloys), stainless steel, aluminum, high strength plastics, or composites.

(20) FIG. 2 illustrates a side view of the example barbell grip 100 of FIG. 1. This would be the view facing one end of a barbell shaft, looking down the longitudinal axis of the shaft, if the barbell grip were attached to the barbell shaft. The cylindrical space between the two shaft collar elements 112 and 114 is more clearly visible than in FIG. 1. When in use this space between 112 and 114 would be occupied by a barbell shaft, and the two shaft collar elements would be compressed against the barbell shift in a locked position, to secure the barbell grip on the barbell shaft. The inner semi-cylindrical surfaces of 112 and 114 may be machined smooth, or appropriate padding or other material may be adhered on the surface to obtain a more secure grip of the barbell shaft and avoid damage to the barbell shaft.

(21) FIG. 3 illustrates a top view of the example barbell grip 100 of FIG. 1, according to an example embodiment of the present invention.

(22) FIG. 4 illustrates a front view of the barbell grip of FIG. 1, looking inward from the end of the cantilever grip arm.

(23) FIG. 5 illustrates a view of the barbell grip of FIG. 1, when the grip is in the open position. The hinge elements 114, 116 and 118 are all visible from this view in the open configuration.

(24) Optionally, a bubble level may be provided as part of the barbell grip 100 to allow a pair of barbell grips to be placed in the identical orientation on a barbell shaft. The bubble level may, e.g., be attached to the cantilever grip arm, the housing of the shaft collar, or the brace arm. FIG. 6 shows an expanded view, from the same perspective as FIG. 1, that details this configuration. The bubble level 160 may include indicia 162 to determine when the barbell grip is in a particular configuration, e.g., with the cantilever grip arm parallel to the floor.

(25) FIG. 7 illustrates two example barbell grips, in a fully closed and secured position, attached to a conventional barbell shaft 10, according to an example embodiment of the present invention.

(26) The barbell shaft 10 extends longitudinally from a first end 12 to a second end 14. For Olympic style bars, the ends 12 and 14 may include a rotating sleeve. Collars 16 and 18 may be provided proximate the ends 12 and 14, respectively. Weight plates of various sizes (not shown) may be placed on the ends 12 and 14, usually with identical weights at either end. A removable collar may be added on each end to secure the weight plates. In the middle of the bar, equidistant from the midpoint of the shaft, knurling 20 and 22 may be provided, to improve the ability of a weightlifter to grip the bar.

(27) Attached at to the barbell shaft 10, preferably at points equidistant from the midpoint of the shaft and preferably in the identical orientation are two identical barbell grips 100a and 100b. Nonequidistant points could be used for exercises favoring one side of the body over the other.

(28) The barbell 10 may be placed on a bench rack or other weightlifting support/fixture. Weights may be attached either before or after placing the bar on the rack or support. The two grips 100a and 100b may also be attached to the bar either before or after placing the bar on the rack. Optional bubble levels in the grips 100a and 100b may be used to ensure they are aligned in the same orientation. A weightlifter then assumes a supine position with the back on a bench under the barbell shaft. Usually the feet are placed on the floor beside or beneath the bench. In a conventional bench press, the weightlifter would grip the barbell shaft, usually with a pronated grip, of the knurled portions 20 and 22. The weightlifter would then lift the barbell shaft from the rack and raise and lower the barbell shaft. When the exercise is completed, the barbell shaft is returned to the rack. A spotter may assist during this process.

(29) When the grips 100a and 100b are attached to the barbell shaft, rather than gripping the knurled portion of the shaft 20, and 22, a weightlifter grips the respective cantilever grip arms of the barbell grips. The bar is lifted by lifting the grips, rather than gripping and lifting the bar directly. Since the cantilever grip arms extend from the bar, the lifter can use a neutral or partially neutral grip, depending on the exact angle the cantilever grip arms extend from the bar. When the bench press exercise is executed, the brace arms may be pressed against the lifter's forearms. This bracing helps to counteract the moment loading on the wrist joint from the off center bar. Bracing can be accomplished either with the barbell on the head side of the hand or the feet side based on user preference.

(30) After the lift, the bar may be returned to the rack, and the barbell grips 100a and 100b can be removed.

(31) The foregoing description of embodiments of the present disclosure has been provided for the purposes of illustration and description. It is not intended to be exhaustive or to limit the invention to the precise forms disclosed. Obviously, many modifications and variations will be apparent to the practitioner skilled in the art. Such changes and modifications can be made without departing from the spirit and scope of the present subject matter and without diminishing its intended advantages. It is therefore intended that such changes and modifications be covered by the appended claims.
