Several definitions that apply throughout this disclosure will now be presented. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean “at least one”.

The term “comprising” means “including, but not necessarily limited to;” it specifically indicates open-ended inclusion or membership in a so-described combination, group, series, and the like.

Without a given definition otherwise, all terms used have the same meaning as commonly understood by those skilled in the art. The terms used herein in the description of the present disclosure are for the purpose of describing specific embodiments only, and are not intended to limit the present disclosure.

As shown into, an embodiment of the present application provides a fitness apparatus. The fitness apparatusincludes a handleand a weight assembly. The weight assemblyincludes a housing, a pin, and a plurality of weights. The housingis fixedly connected to the handle. The pinis movably connected to the housing. The plurality of weightsare arranged in stack and adapted to fit in the housing.

As shown in, the pinis used for selectively positioning one single weightto the housing. When a user lifts the housingby the handle, the selected weightby the pinand all weightsabove the selected weightare lifted together, but the other weightsbelow the selected weightare left behind, allowing the user to quickly and easily adjust the weight of the fitness equipment.

When the user selects the lowest weightby the pin, all weightsare engaged with the housing, setting the weight assemblyto its maximum weight, including the housingand all weights. When no weightsare selected, all weightsremain disengaged from the housing, and the weight assemblyremains at its minimum weight, consisting of the housingalone.

In some embodiments, as shown into, the housingincludes a coupling plate, and each weightincludes a coupling slot. When all the weightsare stacked in alignment, the coupling slotsof all the weightsare aligned vertically. The coupling plateis vertically insertable into the coupling slotsof all the weightsstacked in alignment. The coupling plateincludes a plurality of first pin holes, and each weightincludes a second pin hole. When the coupling plateis inserted into the coupling slotsof all the weightsstacked in alignment, each weight's second pin holeis laterally aligned with a corresponding first pin hole. The pinis laterally insertable into the second pin holeof the selected weightand the corresponding first pin holealigned therewith, to position the selected weightto the housing. When adjusting the total weight of the fitness apparatus, the user needs only vertically reinsert the coupling plateback into the coupling slotsof the remaining weightsand reposition the pinto select another desired weight, enabling rapid and efficient adjustment total weight of the fitness apparatuswithout handling the weights.

In some embodiments, as shown into, the housingincludes two coupling plates, and each weightincludes two coupling slots. When all the weightsare stacked in alignment, the coupling slotson the same side of all the weightsare aligned vertically. Each coupling plateis vertically insertable into the corresponding coupling slotsof all the weightsstacked in alignment. Each coupling plateincludes a plurality of first pin holes, and each weightincludes a second pin hole. When the coupling plateis inserted into the corresponding coupling slotsof all the weightsstacked in alignment, each weight's second pin holeis laterally aligned with two corresponding first pin holesof the two coupling plates. The pinis laterally insertable into the second pin holeof the selected weightand the corresponding two first pin holesaligned therewith, to position the selected weightto the housing. Compared to only one coupling plate, two coupling platescan provide two supporting points for the pin, improving stability between the pinand the housing. In some other embodiments, the number of coupling platesand coupling slotscould be three, four, or five and so on.

In some embodiments, the diameter of each first pin holeis less than or equal to the diameter of each second pin hole, allowing the pinto pass through the second pin holeand insert into the first pin holedespite potential manufacturing tolerances.

In some embodiments, the edges of each first pin holeand each second pin holeare chamfered, and the end of the pinis chamfered, facilitating insertion of the pininto the first pin holesand the second pin holesand preventing the pinfrom causing injury to the user.

In some embodiments, the second pin holeof each weightlaterally extends through exterior surfaces on both sides of the weight, the length of the pinis longer than or equal to the depth of the first pin holeand the second pin holealigned, so that the pincan laterally extend through the weightselected, making the force on the pinmore uniform.

In some embodiments, as shown into, the coupling platefurther includes a rail grooveextended vertically, each weightfurther includes a protrusionin its coupling slot, the protrusionis insertable into the rail grooveand slidable along the rail groove. When the weightsare stacked in alignment, the protrusionsof the weightsare aligned to form a vertical rail, and when the coupling plateis inserted into the coupling slots, the rail is inserted into the rail groove, guiding the coupling plateto be vertically inserted into the coupling slots, and avoiding lateral misalignment between the first pin holeand the second pin hole.

In some embodiments, as shown into, the housingfurther includes a roofand a sidewallperpendicularly connected to each other, and the coupling plateis perpendicularly fixed to the roofand the sidewall. When the weightsare engaged with the housing, the weighton top contacts the roof, and all the weightscontact the sidewall, so the roofand the sidewallrestrict the rotation of the selected weightaround the pinwhen the weightsare lifted by housing.

In some embodiments, as shown into, the sidewallextends laterally to form two flangeson both sides, each flangeis shaped to conform to the outer profile of each weight. When the user inserts the coupling plateinto the coupling slotof all the weightsstacked in alignment, the user can align the flangewith the outer profile of weights, to align the coupling platewith the coupling slot, because it is difficult for the user to observe if the coupling plateis aligned with the coupling slotfrom the top, the flangecan help the user to judge it.

In some embodiments, as shown into, each flangehas a marking areaon its exterior surface, the marking areadisplays weight values (not shown in FIGS.), each weight value corresponds to each weightstacked in the housingand indicates a cumulative weight of the corresponding weightand all the weights above. For example, the weight of each weightis 5 kg, the weight value corresponding to the weighton top layer is 5 kg, the weight value corresponding to the weighton second top layer is 10 kg, and the weight value corresponding to the weighton third top layer is 15 kg, and so on.

In some embodiments, as shown inand, each weightincludes a positioning recessand a positioning projectionon opposite sides, the positioning projectionof one weightis insertable into the positioning recessof an adjacent weightto align each pair of adjacent weightsin a stacked arrangement, so that the coupling slotsare aligned automatically when the weightsare stacked, ensuring that the coupling platecan be inserted into the coupling slotsand the first pin holeand the second pin holeare aligned laterally for inserting the pin.

In some embodiments, as shown inand, a first mounting holeand a second mounting holeare formed on an exterior surface of the housing, for example, the first mounting holeis on the sidewall, and the second mounting holeis on the roof. The handleincludes a first endand a second end, the first endis inserted into the first mounting holeand fixed to the housing, the second endis inserted into the second mounting holeand fixed to the housing, which makes the fitness apparatusbecome a kettlebell.

In some embodiments, as shown inand, the fitness apparatusincludes two weight assemblies. The handleincludes a first endand a second end, and the two weight assembliesare respectively fixed to the first endand the second end, which makes the fitness apparatusbecome a dumbbell. Furthermore, for example, each weight assemblyhas a first mounting holeon its sidewall, the first endand the second endare fixed in the corresponding first mounting hole

In some embodiments, as shown in, the fitness apparatusincludes two weight assemblies. The handleincludes a first rodand a second roddetachably connected, the end of the first rodaway from the second rodis defined as a first end, and the end of the second rodaway from the first rodis defined as a second end. The two weight assembliesare respectively fixed to the first endand the second end, which makes the fitness apparatusbecome a barbell. Furthermore, for example, each weight assemblyhas a first mounting holeon its sidewall, the first endand the second endare fixed in the corresponding first mounting hole

Furthermore, the first rodand the second rodcan be fixed by a screw, and the fitness apparatuscan save packaging space by dividing the handleinto the first rodand the second rod.

In some embodiments, as shown inand, the fitness apparatusfurther includes a base, the baseincludes a baseplate, the baseplateis used for supporting the weight assemblyof the kettlebell or supporting the two weight assembliesof the dumbbell or the barbell. Barriersare formed on the baseplate, the barriersare used for positioning each weight assemblyon the baseplate. Furthermore, the barriersare formed on an edge of the baseplate.

Furthermore, in some embodiments, the baseplatehas projection (not shown in FIGS.) to be inserted into the positioning recessof the lowest weight, to position the lowest weighton the baseplate.

In some embodiments, as shown in, the fitness apparatusfurther includes a bracketand two bases, the two basesare detachably installed on the bracket. Each basecan hold a dumbbell or a kettlebell, so the user can exercise the left arm and the right arm at the same time. Furthermore, the bracketalso includes a beam, which can place towels, water bottles, mobile phones, etc.

In some embodiments, as shown in,, and, the pinis connected to the housingby an elastic piece. The roofhas a buckle slot, one end of the elastic pieceis buckled in the buckle slot, and another end of the elastic pieceis fixed to the pin, so that the pinstays with the housing, thereby preventing the pinfrom being lost or too far away from the housing. For example, the elastic pieceis an elastic rope or a spring.

Furthermore, in some embodiments, as shown in, the pinincludes a pin rodand a holder, the holderis located at an end of the pin rod. The pin rodis used for being inserted into the first pin holeand the second pin hole. The holderis provided with anti-skid patterns, so that the user can grip the holderto move the pin rod.
