The present invention relates to an adjustable exercise device or kettlebell or the like, and more particularly to an adjustable exercise device or kettlebell including an improved compact structure or configuration for allowing the weight members to be easily and adjustably attached to or disengaged from the weight carrier or handle and for allowing the user to easily operate the adjustable kettlebell.
Typical exercise devices or kettlebell devices comprise a normally U or C-shaped central handle member to be grasped or held or carried by the user, and a number of weight plates, weight members or kettle balls or kettle members to be attached onto the ends of the handle member for weight lifting or exercising purposes by the user, or for exercising or training the upper muscle groups of the user.
For example, U.S. Pat. No. 1,917,566 to Wood, U.S. Pat. No. 4,659,079 to Blanchard, U.S. Pat. No. 6,387,022 to Smith, U.S. Pat. No. 7,052,445 to Ekhaus, U.S. Pat. No. 7,182,715 to Anderson, U.S. Pat. No. 7,381,157 to Blateri, U.S. Pat. No. 7,491,157 to Lin, and U.S. Pat. No. 7,563,208 to Chen disclose several of the typical kettlebell devices each also comprising a normally U or C-shaped handle including two legs or limbs attached or mounted or secured to the weight members or kettle balls or kettle members for being held or grasped or carried by the user and for allowing the user to conduct various kinds of weight lifting or exercise operations.
However, the weight members or kettle balls or kettle members may not be easily and quickly and adjustably attached to or disengaged from the weight carrier or handle, and the typical adjustable kettlebell devices include a complicated structure or configuration that may not be easily and quickly made or manufactured by the manufacturers and that may include a complicated making or manufacturing procedure and that may include a greatly increased manufacturing cost.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional adjustable kettlebell devices.
The primary objective of the present invention is to provide an adjustable exercise device or kettlebell including an improved compact structure for allowing the weight members to be easily and quickly and adjustably attached to or disengaged from the weight carrier or handle and for allowing the adjustable kettlebell to be easily operated by the users.
The other objective of the present invention is to provide an adjustable exercise device or kettlebell including an improved compact structure for allowing the adjustable exercise device or kettlebell to be easily and quickly made or manufactured by the manufacturers.
In accordance with one aspect of the invention, there is provided an adjustable exercise device comprising a receptacle including a chamber formed therein, and including a handle device provided thereon, a first weight member and at least one second weight member selectively engageable into the chamber of the receptacle, and a control device including a shaft engaged through the receptacle and engaged into the chamber of the receptacle, and engageable through the first and the at least one second weight members for selectively anchoring either the first or the at least one second weight member to the receptacle with the shaft.
The first and the at least one second weight members each include a bore formed therein for engaging with the shaft of the control device, and the first and the at least one second weight members each include an opening formed therein and communicating with the bore of the first and the at least one second weight members, and the shaft includes a first pin engageable through the opening of the first weight member for selectively engaging with the first weight member, and at least one second pin engageable through the opening of the at least one second weight member for selectively engaging with the at least one second weight member.
The first and the at least one second weight members each include a space formed therein and communicating with the bore and the opening of the first and the at least one second weight members for selectively engaging with the first and the at least one second pin respectively. The first and the at least one second weight members each include at least one depression formed therein and communicating with the bore and the space for selectively engaging with the first and the at least one second pin respectively.
The control device includes an actuating knob attached to the shaft for moving the shaft and the first and the at least one second pins relative to the receptacle. The actuating knob includes a cam member pivotally coupled to the shaft with a pivot axle for moving the shaft and the first and the at least one second pins up and down relative to the receptacle and the first and the at least one second weight members selectively. The receptacle includes a cap disposed thereon, and the cap includes an oblong hole formed therein for slidably engaging with the pivot axle.
The receptacle includes a plurality of indicia provided thereon, and the cap includes an indicator provided thereon for indicating either of the indicia of the receptacle. The receptacle includes at least one peg extended upwardly therefrom, and the cap includes a peripheral slot formed therein for slidably engaging with the at least one peg and for guiding and limiting the cap to rotate relative to the receptacle. The receptacle includes a spring biasing member engaged between the cap and the receptacle for selectively biasing and moving the cap upwardly from the receptacle.
The receptacle includes an upper wall for defining the chamber of the receptacle, and the receptacle includes a passage formed in the upper wall and communicating with the chamber of the receptacle. The receptacle includes at least one engaging member formed in the upper wall, and the first weight member includes at least one key extended therefrom for selectively engaging with the at least one engaging member of the upper wall and for anchoring the first weight member to the receptacle.
The receptacle includes at least one guiding channel formed therein and communicating with the chamber of the receptacle, and the first weight member includes at least one protrusion extended therefrom for slidably engaging with the at least one guiding channel of the receptacle and for preventing the first weight member from pivoting relative to the receptacle. The first weight member includes an engaging member formed in the at least one protrusion, and a cover includes a projection extended therefrom for engaging with the engaging member of the at least one protrusion and for detachably securing the cover to the first weight member.
The first weight member includes at least one recess formed therein, and the at least one second weight member includes at least one key extended therefrom for selectively engaging with the at least one recess of the first weight member and for anchoring the at least one second weight member to the first weight member.
Further objectives and advantages of the present invention will become apparent from a careful reading of the detailed description provided hereinbelow, with appropriate reference to the accompanying drawings.
Referring to the drawings, and initially to
The receptacle 10 includes one or more (such as two) keys or pegs 15 extended upwardly therefrom, such as extended upwardly from the flat upper wall 12 and spaced from each other, and includes a bore or passage 16 formed in the upper wall 12 and communicating with the chamber 11 of the receptacle 10, and includes a number of scales or indicia 17 formed or provided on the outer peripheral portion thereof for indicating the weight of the kettlebell device.
