- the handle 10 has a handle portion 11 comprising a loop structure that attaches to the handle body 12 in two locations (though different designs could comprise more or fewer attachment points).
- the handle body 12 further comprises a handle body receiver 13 which is designed to mate with a threaded top cap 51 at a threaded top cap projection 52 .
- the threaded top cap projection 52 is cylindrical and projects down into the handle body receiver 13 which has a slightly larger diameter so that the threaded top cap 51 can freely turn.
- the threaded top projection 52 aids alignment and stability of the attachment of the handle 10 to the upper body 20 .
- the surface of the threaded top cap 51 serves as a gripping point for the user's hand to tighten and fix the position of the handle 10 or loosen the handle 10 and allow free rotation to the desired orientation.
- the handle body 12 further comprises handle body grooves 14 that radiate from the center axis of the handle 10 .
- the handle body grooves 14 interdigitate with upper body ridges 24 to lock the orientation of the handle 10 relative to the dumbbell (not shown).
- the handle 10 has eight handle body grooves 14 that allow the handle 10 to rotate at forty-five degree increments relative to the dumbbell.
- the threaded top cap 51 When the threaded top cap 51 is loosened it releases the frictional grip between the handle body grooves 14 and the upper body ridges 24 allowing freedom of rotation between the handle 10 and upper body 20 .
- Alternative embodiments could utilize a greater number of handle body grooves 14 to increase the number of potential configurations.
- the handle body bottom surface 15 could have various concave shaped modifications that could receive complementary convex shaped modifications on the upper body top surface 25 .

Abstract
The present invention relates to a new handle for adapting kettlebell weights and for new modes of lifting weights.
Description
- Continuation-in-part of United States pending patent application Ser. No. 13/232,973 dated Sep. 14, 2010 and claiming priority to United States provisional application No. 61/382,691 dated Sep. 14, 2010 the contents of which are hereby incorporated by reference.
- The present invention relates to exercise devices and methods of use thereof. In particular, the invention relates to a handle for converting standard weights into kettlebell weights.
- Mixed martial arts have become very popular and have ushered in a new wave of work out routines that are taken from the past. Today martial artists use historical but proven techniques to improve strength and performance. A wide variety of weight training techniques are known, including the fixed or variable weight type of exercise machines, cast dumbbells, and the free weight/bar combination. However, owning a useful set of weights with the weights available in various sizes can be prohibitively expensive.
- There are a couple of basic forms of dumbbells and most have a fixed weight. Fixed weight dumbbells are ubiquitous in today's gyms. However, kettlebells have a generally asymmetric weight that challenges muscles uniquely and therefore generally are only available in limited or specialized training facilities. Various adjustable dumbbells have been developed. Representative examples include, U.S. Pat. Nos. 4,948,123; 4,556,690; 4,913,422; 4,900,016; 4,880,229; 4,743,017; and 4,529,198. Each of these references, however, addresses only certain aspects of an adjustable dumbbell, such as releaseability, interlocking of the weights, etc.
- The invention provides a releasable handle that adapts any commercially available dumbbell into a kettlebell.
- Additionally, the handle can be adapted to rotate about an axis that allows the user to shift the center of mass to create unique weight lifting pathways to target muscles in unique ways.
- Additionally, the invention provides a method of exercise comprising the use of the kettlebell invention.
- In view of the shortcomings of the prior art, it is the object of this invention to provide a quickly releasable handle that can mount and detach from commercially available dumbbells. It is also desirable to have the handle adjust to various orientations about the dumbbell to create different centers of mass to challenge the weight lifter and accommodate different ranges of motion than would otherwise be possible with a fixed dumbbell.
- Further objects and advantages of the invention will become apparent to those skilled in the art upon reading and consideration of the following description of a preferred embodiment and the accompanying drawings.

FIG. 1 shows an exploded line drawing of a preferred embodiment. There are four main components comprising a handle 10, anupper body 20, alower body 30, and abottom cap 40. The handle 10 has ahandle portion 11 comprising a loop structure that attaches to thehandle body 12 in two locations (though different designs could comprise more or fewer attachment points). Thehandle body 12 further comprises ahandle body receiver 13 which is designed to mate with a threadedtop cap 51 at a threadedtop cap projection 52. The threadedtop cap projection 52 is cylindrical and projects down into thehandle body receiver 13 which has a slightly larger diameter so that the threadedtop cap 51 can freely turn. The threadedtop projection 52 aids alignment and stability of the attachment of the handle 10 to theupper body 20. The surface of the threadedtop cap 51 serves as a gripping point for the user's hand to tighten and fix the position of the handle 10 or loosen the handle 10 and allow free rotation to the desired orientation. - The
handle body 12 further comprises handle body grooves 14 that radiate from the center axis of the handle 10. The handle body grooves 14 interdigitate withupper body ridges 24 to lock the orientation of the handle 10 relative to the dumbbell (not shown). In the preferred embodiment the handle 10 has eight handle body grooves 14 that allow the handle 10 to rotate at forty-five degree increments relative to the dumbbell. When the threadedtop cap 51 is loosened it releases the frictional grip between the handle body grooves 14 and theupper body ridges 24 allowing freedom of rotation between the handle 10 andupper body 20. Alternative embodiments could utilize a greater number of handle body grooves 14 to increase the number of potential configurations. In a further embodiment the handle body bottom surface 15 could have various concave shaped modifications that could receive complementary convex shaped modifications on the upper body top surface 25. For example, a golf ball like handle body bottom surface 15 could match contact with the upper body top surface 25 in almost any orientation along the handle 10 axis. The handle 10 is fixed in orientation relative to theupper body 20 via the upper body threadedconnector 21 which passes through the handle body central axis 16 and washer 17 (optional) and into the threaded top cap receiver 56. - The
upper body 20 andlower body 30 mate together at the proximal upper body surface 22 and proximal lower body surface 32 and the distal upper body surface 23 and the distal lower body 33 mate, respectively, in the closed position. The proximal and distal surfaces define a passage 81 to receive a dumbbell (not shown). Theupper body 20 andlower body 30 are connected at the proximal face by a quick release 60 that comprises aquick release body 61 and aquick release head 62. Theupper body 20 andlower body 30 are connected at the distal face of the upper body by a sliding plate 65. The sliding plate 65 has aupper mount hole 66 and alower mount hole 67 that accommodate anupper pin 68 and alower pin 69. Theupper pin 68 flexibly mounts the sliding plate 65 to theupper body 20 atupper body mounts 28 and thelower bolt 69 flexibly mounts sliding plate 65 to thelower body 30. Theupper pin 68 flexibly mounts the sliding plate 65 to theupper body 20 atupper body mounts 28 and thelower pin 69 flexibly mounts sliding plate 65 to thelower body 30 at the lower body mounts 38. When the quick release 60 is in the unlocked and open position, theupper body 20 andlower body 30 may pivot relative to one another to form a c-shape and expose thedumbbell mounting surface 37. In an alternative embodiment, either theupper body 20 could have modified upper body mounts 28 that are shaped like parallel tracks instead of simple circles adapted for receiving theupper pin 68 that would allow theupper pin 68 to keep the sliding plate 65 attached to theupper body 20 but allow freedom of movement along the vertical axis. This could make opening and accessing the dumbbell mounting surface easier than a simple pivot. Additionally, the sliding plate 65 could accommodate larger dumbbell handles in thedumbbell mounting surface 37 if it could move along the vertical axis. The alternative embodiment should not be construed to limit the modification of the upper body mounts 28 as the sole method of achieving a variable sizeddumbbell mounting surface 37. It would be similarly possible to modify the lower body mounts 38 to allow freedom of movement or to modify both the upper and lower body mounts 28,38. - The quick release 60 is comprised of a
quick release body 61, ahead 62, a threadedend 63, a head mount hole 64, and ahead mount pin 74 that is attached to theupper body 20 at the upper body head mounts 29. Thehead mount pin 74 passes through one side of the upper body head mount 29 then through thehead 62 and in to the other side of the upperbody head mount 29. Thequick release body 61 can pivot away from thelower body 30 in the unlocked and open position while remaining attached to theupper body 20 via thehead 62. Thequick release body 61 can remain flush against theupper body 20 andlower body 30, but in the preferred embodiment, theupper body 20 has a quick release head receiver 72 with upper body mounts 29 on either side adapted to receive thehead 62 andhead mount pin 74. Theupper body 20 may be further adapted to have a grove to adjust the angle of thequick release body 61 relative to thelower body 20 in the closed position. Thequick release body 61 is parallel to the vertical axis when thequick release body 61 is in the closed position. To lock thequick release body 61 in the closed position, the threadedend 63 is inserted into abottom cap 40 at the bottom capquick release hole 41. The threadedend 63 of thequick release body 61 is further locked in place with awingnut 42. - The
bottom cap 40 can be adapted to have a flat bottom surface 43 to set on the floor. In a preferred embodiment thebottom cap 40 can have a low profile so that a dumbbell will set on the floor and thebottom cap 40 will be suspended over the floor. The bottom cap proximal surface can be sloped in a preferred embodiment to accept thequick release body 61 with a sliding plate 65 mounted at upper body mounts 28 and lower body mounts 38 wherein theupper body 20 andlower body 30 pivot at fixed a fixed distance. The lower body bottom surface 39 could be tapered to have a complementary surface to the bottom cap top surface 45. Thebottom cap 40 may have a recess in the bottom surface 43 to recess thewingnut 42 so that thewingnut 42 cannot catch on clothing or other materials during use. - When the
quick release body 61 is in the open position theupper body 20 andlower body 30 are free to open and receive adumbbell 80. Thedumbbell mounting surface 37 is disclosed as a smooth surface, but alternative embodiments could be designed to accommodate commercially available dumbbells. Additional features could include surface modification to increase texture to improve grip so that thedumbbell 80 will not slip or move once thequick release body 61 is in the closed and locked position. -
FIG. 2 shows a preferred embodiment in the closed and locked position.FIG. 3 illustrates a preferred embodiment in an exploded solid state. The handle 10,upper body 20, thelower body 30 andbottom cap 40 are constructed of machined metal. However, it may be possible to produce handle 10,upper body 20, thelower body 30 orbottom cap 40 with die cast metal. Alternatively, parts may be made of high strength polymers to reduce weight and cost.FIG. 4 shows a preferred embodiment in a closed and locked position. Additionally, thequick release body 61 is recessed into both theupper body 20 andlower body 30, with only the threadedend 63 visible and protruding through thebottom cap 40. The threadedend 63 is locked in place by awingnut 42. -
FIG. 5 shows a preferred embodiment in a closed and locked position with adumbbell 80. Thequick release body 61 is recessed in theupper body 20 andlower body 30. -
FIG. 6 shows a preferred embodiment with thequick release body 61 locked in place withwingnut 42 and adumbbell 80 locked in place. -
FIGS. 7-10 show drawings of an alternative embodiment that does not require anend cap 40 to lock the dumbbell (not shown) into place. There are three main components comprising a handle 110, anupper body 120, and alower body 130. The handle 110 has a handle portion 111 comprising a loop structure that attaches to thehandle body 112 in two locations, though different designs could comprise more or fewer attachment points. Thehandle body 112 further comprises ahandle body receiver 113 which is designed to mate with a threadedtop cap 151 at a threadedtop cap projection 152. The threadedtop cap projection 152 is cylindrical and projects down into thehandle body receiver 113 which has a slightly larger diameter so that the threadedtop cap 151 can freely turn. Thehandle body 112 further comprises handle body grooves 114 that radiate from the center axis of thehandle body 112. The handle body grooves 114 interdigitate withupper body ridges 124 to lock the orientation of the handle 110 relative to the dumbbell (not shown). In the preferred embodiment the handle 110 has eight handle body grooves 114 that allow the handle 110 to rotate at forty-five degree increments relative to thedumbbell 80. Alternative embodiments could utilize a greater number of handle body grooves 114 to increase the number of potential configurations. In a further embodiment the handle body bottom surface could have various concave shaped modifications that could receive complementary convex shaped modifications on the upper body top surface. For example, a golf ball like handle body bottom surface could match contact with the upper body top surface in almost any orientation along the handle 110 axis. The handle 110 is fixed in orientation relative to theupper body 120 via a threadedconnector 121 that is permanently fixed in theupper body 120. The threadedconnector 121 passes through a spring 191 and the handle body central axis and into the threaded top cap receiver. When the threadedtop cap 151 is tightened down it compresses the spring 191 and forces the handle 110 to lock into place. - The
upper body 120 andlower body 130 are connected at the proximal face by a quick release mechanism that comprises aquick release body 192, aproximal mounting pin 196 disposed in theupper body 120, aspacer washer 193, and arelease knob 194. The quick release mechanism determines whether theupper body 120 andlower body 130 are in a locked closed position or in an unlocked open position. Theupper body 120 andlower body 130 are permanently connected at a distal mount comprising adistal mounting pin 195 that passes through two upperbody mounting holes 199 disposed in a distal portion of theupper body 120 and lowerbody mounting hole 198 disposed in the distal portion of thelower body 130. The distal mount allows theupper body 120 andlower body 130 to open and receive a dumbbell when the quick release mechanism is in an unlocked position. Theupper body 120 has a proximalmounting pin hole 200 that receives aproximal mounting pin 196. The mountingpin 196 further passes through a proximalmount pin hole 197 disposed in a top portion of thequick release body 192. - When the
release knob 194 is untightened, thequick release body 192 can pivot away from thelower body 130, allowing the lower body to rotate about thedistal mounting pin 195 into an open position to receive a dumbbell. To close the quick release, thequick release body 192 is pivoted back towards thelower body 130 it will contact a proximal groove in thelower body 130, and therelease knob 194 is tightened again to achieve the closed position with a dumbbell attached. Thequick release body 192 has a lower portion that is threaded and passes through thespacer washer 193 into therelease knob 194. Therelease knob 194 is threaded and when twisted pushes thespacer washer 193 against the lockingseat 183 disposed in the proximal groove of thelower body 130. Thequick release body 192 is completely tightened whenspacer washer 193 is pressed tightly against the lockingseat 183, the locked position. - The dumbbell mounting surface is disclosed as a smooth surface, but alternative embodiments could be designed to accommodate commercially available dumbbells. Additional features could include surface modification to increase texture to improve grip so that the
dumbbell 80 will not slip or move once thequick release body 192 is in the closed and locked position. -
FIGS. 11-17 show drawings of an alternative embodiment that does not require a threaded release knob or an end cap to lock a dumbbell into place.FIG. 11 shows an exploded line view of the handle and locking mechanism. There are three main components comprising ahandle 100, anupper body 200 and alower body 300. Thehandle 100 has ahandle portion 101 comprising a loop structure or contour multi grip handle that attaches to thehandle body 102 in two locations (though different designs could comprise more or fewer attachment points. - The
handle body 102 further comprises ahandle body receiver 103 which is designed to accommodate a threadedtop cap 104 at a threadedtop cap projection 105. The threadedtop cap projection 105 is cylindrical and projects down into thehandle body receiver 103 which has a slightly larger diameter so that the threadedtop cap 104 can freely turn. Thehandle body 102 further comprises handlebody grooves 106 that radiate from the center axis of thehandle body 102. Thehandle body grooves 106 interdigitate withupper body ridges 201 to lock the orientation of thehandle 100 relative to the dumbbell (not shown). In the preferred embodiment thehandle 100 has eighthandle body grooves 106 that allow thehandle 100 to rotate at forty-five degree increments relative to the dumbbell. Alternative embodiments could utilize a greater number ofhandle body grooves 106 to increase the number of potential configurations. In a further embodiment the handle body bottom surface could have various concave shaped modifications that could receive complementary convex shaped modifications on the upper body top surface. Thehandle 100 is fixed in orientation relative to theupper body 200 via a threadedconnector 107 that is permanently fixed in theupper body 102 and which screws into the threadedconnector port 202 of the upper body. The threadedconnector 107 passes through aspring 108 and the central axis of thehandle body 102 and into the threadedtop cap projection 105. When the threadedtop cap 104 is tightened down it compresses thespring 108 and forces thehandle 100 to lock into place. When the threadedtop cap 104 is not fully tightened down upon the threadedconnector 107 thehandle 100 and theupper body 200 can rotate freely relative to one another about the axis of the threadedconnector 107. - The
upper body 200 andlower body 300 are connected by a cam-lock quick release mechanism that comprises a cam-lock receiver 301, and a cam-lock latch 302. The cam-lock receiver 301 is permanently attached to theupper body 200 by adistal mounting pin 303 which passes through distal mounting holes in both theupper body 304 and in the cam-lock receiver 305. Thecam lock receiver 301 is free to rotate about the axis of thedistal mounting pin 303. When thecam lock receiver 301 rotates down and away from theupper body 200 it reaches the open, unlocked position and when it 301 rotates upwards and towards the proximal face of theupper body 200 it reaches the open, and lockable position. Between theupper body 200 and the cam-lock receiver 301 are plastic or rubber bar grip inserts 306 to prevent slippage of the bar while in the cam-lock mechanism. - The cam-
lock latch 302 is detachably connected to theupper body 200 by a proximal cam-locklatch mount hole 307 and a proximal cam-lock latch pin 308. The cam-lock latch pin 308 passes through one side of the proximal cam-locklatch mount hole 307 and then through a female threadedadjustment sleeve 309, which is also disposed with a hole to accommodate the proximal cam-lock latch pin 308. The male threadedadjustment connection 310 screws detachably into the female threadedadjustment sleeve 309. The male threadedadjustment connection 310 is attached to the proximal face of theupper body 200 by a male adjustmentconnection hinge pin 311 which passes through a mountinghole 312 in the male threadedadjustment connection 310. - The cam-
lock latch 302 and the female threadedadjustment sleeve 309 can be rotated around the male threadedadjustment connection 310 and this increases or decreases the distance that the cam-lock latch 302 is from theupper body 200 . By rotating the cam-lock latch 302 about the axis formed between the female threadedadjustment sleeve 309 and the male threadedadjustment connection 310 the distance between theupper body 200 and the cam-lock latch 302 can be increased (loosening the lock) or decreased (tightening the lock) thereby allowing the device to be tightened around a barbell, and around barbells of various sizes not shown. - When the cam-
lock latch 302 is opened, it pivots around the axis of the proximal cam-lock latch pin 308, downwards and away from thelower body 300 into the unlocked and open position. This allows the cam-lock receiver 301 to pivot around the axis of thedistal mounting pin 303 downwards and away from the upper body in the opposite direction, towards the distal face of theupper body 200, and this is the open position that is free to receive a dumbbell. When the dumbbell bar is inserted into the upper body the cam-lock receiver 301 is then rotated to the closed position, and then the cam-lock latch is rotated to the closed position in order to grip the dumbbell tightly. -
FIG. 12 shows a side view of a preferred embodiment in a closed and locked position with the cam-lock receiver rotated closed towards the proximal face and the cam-lock rotated closed towards the distal face.FIG. 13 shows a view of the proximal face of a preferred embodiment where both the cam-lock receiver and cam-lock latch are in the closed position and where the male threadedadjustment connection 310 is screwed into the female threadedadjustment sleeve 309.FIG. 14 . shows a view of the distal face of a preferred embodiment in the closed and locked position.FIG. 15 shows an exploded view of theupper body 200 and handle 100 where the threadedconnector 107 can be screwed into the threadedconnector port 202 in the center of theupper body 200, and is passed inside of aspring 108 up through the central of thehandle base 102 where it is received by the threadedtop cap projection 105.FIGS. 16 and 17 further show perspective views of a preferred embodiment in a closed and locked position. - Additional modifications and improvements of the present invention may also be apparent to those skilled in the art. Thus, the particular combination of parts described and illustrated herein are intended to represent only one embodiment of the invention, and is not intended to serve as limitations of alternative devices within the spirit and scope of the invention.
