DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference now to the drawings, and in particular to FIGS. 1 through 5 thereof, a new dumbbell bar accessories embodying the principles and concepts of an embodiment of the disclosure and generally designated by the reference numeral 10 will be described.

As best illustrated in FIGS. 1 through 5, the rotatable handle for a dumbbell bar 10 generally comprises a first plate 12 that has an upper face 14 and a lower face 16, and a second plate 18 that has a top surface 20 and a bottom surface 22. The bottom surface 22 is pivotally coupled to the upper face 14, such that the first plate 12 and the second plate 18 are freely rotatable. The second plate 18 may be rotatable by 180 degrees relative to the first plate 12. The first plate 12 and the second plate 18 are round, and the second plate 18 is circumferentially smaller than the first plate 12.

A grip 24 is positioned on the lower face 16, such that the grip 24 is configured for grasping by the hand of a user. The grip 24 comprises a pair of sidebars 26. Each sidebar 26 has a first end 28 coupled to the lower face 16 proximate to a perimeter 30 of the first plate 12, such that the sidebars 26 are disposed at 180 degrees along the perimeter 30. The sidebars 26 have opposing edges 32. Each opposing edge 32 comprises a set of three arcuate curves 34, such that the opposing edges 32 meet and define a second end 36 of the sidebar 26. Each of opposing ends 38 of a crossbar 40 is coupled proximate to a respective second end 36 of the sidebars 26. The crossbar 40 is substantially circular when viewed longitudinally. The crossbar 40 has an inner surface 42 facing the lower face 16 of the first plate 12. The inner surface 42 has a set of four indentations 44, such that the indentations 44 are configured to accommodate the four fingers of a hand inserted into the grip 24.

A clamp 46 is coupled to and positioned on the top surface 20. The clamp 46 is complimentary to a dumbbell bar, such that the clamp 46 is configured to secure the second plate 18 to the dumbbell bar. The clamp 46 comprises a base 48 coupled to and extending from the top surface 20 of the second plate 18. A channel 50 is positioned in a top 52 of the base 48. A clasp 54 is hingedly coupled to a first edge 56 of the channel 50, such that the channel 50 and the clasp 54 form a tube 58 when the clasp 54 is closed. The tube 58 is complimentary to the dumbbell bar. The tube 58 is circular when viewed longitudinally. A first coupler 60 is coupled to a first side 62 of the clasp 54. A second coupler 64 is coupled to the base 48 proximate to a second edge 66 of the channel 50. The second coupler 64 is complimentary to the first coupler 60, such that the second coupler 64 is positioned to engage the first coupler 60 to secure the clasp 54 in a closed position. The first side 62 of the clasp 54 comprises an extension 68. Each of a plurality of holes 70 is positioned through the extension 68. The second coupler 64 comprises a plurality of orifices 72. Each orifice 72 is alignable with a respective one of the plurality of holes 70 in the extension 68. The orifices 72 are threaded. Each of a plurality of screws 74 that is complimentary to the orifices 72 is insertable through a respective one of the holes 70 and threadable into a respective one of the orifices 72, such that the clasp 54 is securable around the dumbbell bar.

A penetration 76 is positioned at a center 77 of the clasp 54. The penetration 76 is threaded. A bolt 78 that is complimentary to the penetration 76 can be tightened to prevent the dumbbell bar from rotating in the tube 58. Each of the screws 74 and the bolt 78 has a tightening ring 79 coupled to a terminus 80 that is distal from the clasp 54.

In use, a pair of the rotatable handles 10 are positionable with a respective channel 50 and a respective clasp 54 configured to attach to a dumbbell bar, such that the user can insert one hand into each grip 24, and such that rotational movement of the inserted hands is allowed during movement of the dumbbell bar due to the rotational coupling of a respective first plate 12 and a respective second plate 18. Enabling the user to rotate their hands while exercising with the dumbbell bar can help prevent injuries, particularly shoulder injuries.

With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.

Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be only one of the elements.
