Description
- Various types of inertial exercise devices are known in the prior art, most requiring the use of fitted springs to elastically resist the acceleration of a weight accelerated between a first position and second position. This elastic resistance requires the application of additional force to accelerate the weight to overcome the resistance, thereby engendering increased physical exertion relative the mass accelerated. However, what is needed is an inertial dumbbell exercise device that enables setting a range of resistance, whereby the acceleration of each of a pair of weights of each of a first and second weight assembly requires more or less force relative the setting selected.
- The present inertial dumbbell exercise device, then, includes a first and second weight assembly disposed upon a respective first and second end of a handle, each of said weight assemblies including a rod disposed perpendicularly and slidably thereupon, a pair of weights disposed endwise upon said rod, and a rubber sleeve disposed between each of said pair of weights and said handle, wherein movement of the handle in a first direction accelerates one of said pair of weights from a first position to a second position against the elastic force of the respective rubber sleeve, and movement of the handle in a second and opposite direction accelerates the other of said pair of weights from a first position to a second position against the elastic force of the respective rubber sleeve, whereby increased exertion is required to accelerate each of said pair of weights relative the force required to accelerate an equivalent mass absent the action of said rubber sleeve, and whereby each of said pair of weights and each respective rubber sleeve is interchangeable to provide for increased exertion required to accelerate said weights between the first position and the second position.
- The present invention relates to an inertial dumbbell exercise device, and more particularly, to an inertial dumbbell exercise device that includes a first and second weight assembly disposed upon a respective first and second end of a handle, each of said weight assemblies including a rod disposed perpendicularly and slidably thereupon, a pair of weights disposed endwise upon said rod, and a rubber sleeve disposed between each of said pair of weights and said handle, wherein movement of the handle in a first direction accelerates one of said pair of weights from a first position to a second position against the elastic force of the respective rubber sleeve, and movement of the handle in a second and opposite direction accelerates the other of said pair of weights from a first position to a second position against the elastic force of the respective rubber sleeve, whereby increased exertion is required to accelerate each of said pair of weights relative the force required to accelerate an equivalent mass absent the action of said rubber sleeve, and each of said pair of weights of each of the first and second weight assemblies and each respective rubber sleeve is interchangeable to provide for increased exertion required to accelerate said weights between the first position and the second position.
- The general purpose of the inertial dumbbell exercise device, described subsequently in greater detail, is to provide an inertial dumbbell exercise device which has many novel features that result in an inertial dumbbell exercise device which is not anticipated, rendered obvious, suggested, or even implied by prior art, either alone or in combination thereof.
- The present device provides an inertial exercise tool that requires physical exertion to accelerate a first and second weight assembly, disposed endwise upon a handle, against the elastic action of a respective rubber sleeve. The first weight assembly is moveably disposed upon a first end of the handle and the second weight assembly is moveably disposed upon a second end of the handle. Each of the first and second weight assemblies includes a rod slidably disposed perpendicularly at each respective first and second end of the handle. A pair of weights is disposed endwise upon said rod. Each of a pair of moveable collars is disposed upon the rod between each of the pair of weights and the handle. A rubber sleeve is disposed between each of the pair of weights and each of the pair of moveable collars.
- Each of the pair of weights of each of the first and second weight assemblies is moveable between a first position and a second position. When the handle is moved in a first direction, one of the said pair of weights is accelerated from a first position to a second position. Said one of said pair of weights is accelerated to compress the respective rubber sleeve, which rubber sleeve elastically resists compression. Increased force is therefore required when said one of said pair of weights is accelerated against said rubber sleeve than would otherwise be required to accelerate said one of said pair of weights to the second position absent the action of the rubber sleeve.
- When the handle is moved in a second direction, said second direction opposite the first direction, the other of said pair of weights is accelerated from the first position to the second position against the action of the respective rubber sleeve, in like manner as described previously for said one of said pair of weights. Thusly, movement of the handle back and forth accelerates each of the pair of weights of each of the respective first and second weight assemblies back and forth between the first and second position whereby, when one of the pair of weights is moved to the second position, the other of said pair of weights is moved to the first position, and vice versa, each of the pair of weights engaging and compressing the respective rubber sleeve when moved to the respective second position.
- A dial is included disposed endwise on each of the first and second ends of the handle. Said dial is in operational communication with a pair of brace members connected to each of the respective pair of moveable collars disposed upon each of the first and second weight assemblies. When the dial is rotated in a first direction, each of the pair of brace members is extended outwards away from the handle, and each of the pair of moveable collars is moved to a position less proximal the handle, a position that compressibly engages each of the pair of moveable collars with each respective rubber sleeve disposed between each of the pair of weights and each of the respective pair of moveable collars. When the dial is rotated in a second direction, each of the pair brace members is retracted towards the handle by the rotational action of the dial, and each of the pair of moveable collars is pulled to a position more proximal the handle.
- The dial is configured to rotate through a plurality of settings wherein each of the pair of moveable collars is moveable between a plurality of positions between each of the pair of weights and the handle, whereby each respective rubber sleeve is compressed between a maximum compression and a maximum decompression. Each respective first and second weight assembly is most easily accelerated to the second position when each respective rubber sleeve disposed thereupon is maximally compressed and each respective first and second weight assembly is least easily accelerated to the second position when each respective rubber sleeve is maximally decompressed. Therefore, a range of elastic resistance of each respective rubber sleeve is selectable by means of the dial disposed to rotatably engage each of the pair of moveable collars with each respective rubber sleeve between a maximum compression and a maximum decompression.
- It should be noted that no springs are required for operation of the present inertial dumbbell exercise device. Each respective rubber sleeve provides the necessary elasticity to resist compression when one of the pair of weights is accelerated against said rubber sleeve. Said resistance requires additional physical exertion to accelerate said one of said pair of weights relative the acceleration of an equivalent mass absent the resistive action of said rubber sleeve.
- Moreover, it is considered that each of the pair of weights of each of the first and second weight assemblies may be interchangeable with alternately available weights having different masses whereby the force required to accelerate said weights is increased and alternately decreased, as desired, depending on the weights selected. Each respective rubber sleeve, also, is considered interchangeable with additional sleeves having an increased or decreased compressive resistance to the acceleration of said weights whereby increased or decreased force is required to accelerate said weights to the second position against the action of said rubber sleeve, as desired, depending on the particular rubber sleeve selected.
- Thus has been broadly outlined the more important features of the present inertial dumbbell exercise device so that the detailed description thereof that follows may be better understood and in order that the present contribution to the art may be better appreciated.
- Objects of the present inertial dumbbell exercise device, along with various novel features that characterize the invention are particularly pointed out in the claims forming a part of this disclosure.

FIGS. 1 through 10 thereof, example of the instant inertial dumbbell exercise device employing the principles and concepts of the present inertial dumbbell exercise device and generally designated by thereference number 10 will be described. - Referring to
FIGS. 1 through 10 a preferred embodiment of the present inertialdumbbell exercise device 10 is illustrated. - The present inertial
dumbbell exercise device 10 has been devised to provide an exercise tool that requires human force to accelerate each of afirst weight assembly 26 and asecond weight assembly 28 disposed endwise upon ahandle 20 against arespective rubber sleeve 36 whichrubber sleeve 36 elastically compresses to resist the movement of saidweight assemblies respective rubber sleeve 36 decompressed, and a second position, with eachrespective rubber sleeve 36 compressed, against the elasticity of eachrespective rubber sleeves 36, creates muscle mass in a body using the inertialdumbbell exercise device 10. Resultantly, less mass is required upon thehandle 20 than would otherwise be required because the inertia of theweight assemblies weight assemblies respective rubber sleeve 36 relative the force required to accelerate saidweight assemblies respective rubber sleeve 36. - Discussing now the preferred embodiment of the
instant device 10, the inertialdumbbell exercise device 10 includes ahandle 20 having afirst end 22 and asecond end 24. Afirst weight assembly 26 is movably disposed on thefirst end 22 and asecond weight assembly 28 is likewise movably disposed on thesecond end 24. Each of said first andsecond weight assemblies rod 30 moveably disposed perpendicularly through thehandle 20, a pair ofmoveable collars 32 disposed around therod 30 on either side of thehandle 20, each of saidmoveable collars 32 disposed proximal thehandle 20, a pair ofweights 34 disposed at either end of therod 30, and arubber sleeve 36 disposed between eachmoveable collar 32 and each of the pair ofweights 34. - Said
rubber sleeve 36 is elastically compressible and resists compression by exerting a force opposite the direction in which saidrubber sleeve 36 is compressed. It should be noted that the term “rubber” as used herein is not meant to limit saidrubber sleeve 36 to fabrication from rubber per se, but the term “rubber” is taken to include rubberlike materials, polymeric substances, and other compressibly elastic materials that may be suited to the intended function of saidrubber sleeve 36 as disposed to elastically resist compression when compressed in the manner subsequently described. - The
rod 30 of each of the first and second weight assemblies 26, 28 is slidably moveable within thehandle 20 respective first andsecond end handle 20 is moved in a first direction, one of the pair ofweights 34 compressibly engages therespective rubber sleeve 36. When thehandle 20 is moved in a second direction, the other of the pair ofweights 34 compressibly engages the otherrespective rubber sleeve 36. Force is therefore required to move each of the pair ofweights 34 to compress eachrespective rubber sleeve 36 when moving each of the pair ofweights 34 from a respective first position to the respective second position. Physical exertion is therefore required to operate thedevice 10, and the action of eachrespective rubber sleeve 36 compressibly resisting the acceleration of each of the pair ofweights 34 of each of the respective first andsecond weight assemblies respective rubber sleeve 36. - To control the resistance applied to said
moveable collars 32 when accelerating each of said pair ofweights 34 against therespective rubber sleeve 36, adial 38 is disposed upon thehandle 20 at thefirst end 22 and thesecond end 24. Thedial 38 is in operational communication with each respective pair ofmoveable collars 32. A pair ofbrace members 40 is disposed upon thedial 38, saidbrace members 40 connecting saiddial 38 to each respective pair ofmoveable collars 32. Thedial 38 is rotatable between a plurality ofsettings 42 that extend each of the pair ofbrace members 40 when thedial 38 is rotated in a first direction and retract each of the pair ofbrace members 40 when thedial 38 is rotated in a second direction (seeFIGS. 6 and 7 ). Each respective pair ofmoveable collars 32 is thereby moveable between a plurality of positions that alternately compress and decompress eachrespective rubber sleeve 36 to alter the difficulty of accelerating each of the pair ofweights 34 against therespective rubber sleeve 36. - The
dial 38 may include a plurality of lockingteeth 44 configured to releasably secure thedial 38 within a set position within the handle 20 (seeFIG. 9B ). Aspring member 46 may be included to releasably secure thedial 38 in position once thedial 38 has been moved to a specific position. Thedial 38 may therefore be retractably housed upon thehandle 20, wherein thedial 38 is pulled outwards, away from the respective first andsecond end handle 20 with each of the lockingteeth 44 disposed in each of a plurality ofholes 48 configured to receive each of the plurality of lockingteeth 44 therein. thedial 38 is thusly releasably secured in position by means of the lockingteeth 44 and each respective pair of lockingcollars 32 is moved to the desired position between the maximum compression and maximum decompression of eachrespective rubber sleeve 36. - It should be noted that interchangeable weights are envisioned to be included with the
device 10, whereby each of the pair ofweights 34 of each of the respective first andsecond weight assemblies respective rubber sleeve 36 may also be replaced with alternate rubber sleeves of varying elasticity to create a greater or lesser resistance to accelerating the mass of each of said pair ofweights 34, as desired. Therefore, ranges of forces are selectable to accelerate the first andsecond weight assemblies device 10 among a plurality of exercises.
