An apparatus and system for storing and transporting exercise equipment, particularly weightlifting equipment including barbells and weight plates, dumbbells, and kettlebells. The system provides for rolled transport, and facile compact storage, of weightlifting equipment. An embodiment of the system includes a front frame and a rear frame. Means are provided for pivotally connecting the front joining section to the rear joining section. A first axle may be inserted through front axle holes in the front frame and a second axle may be inserted through rear axle holes in the rear frame. When the first axle is inserted through the front axle holes, and when the second axle is inserted through the rear axle holes, a barbell weight plate may be disposed on each end of each axle to serve as a wheel upon which the frames may be rolled.

BACKGROUND OF THE INVENTION

Technical Field

The present invention relates generally to the field of exercise equipment, particularly to weightlifting devices, and specifically to a system and apparatus for storing and moving exercise equipment including weightlifting devices.

Description of Background Art

Exercise equipment of many kinds and functions have long been known. An increasingly popular type of exercise devices are weightlifting systems and sets. The lifting of weights can promote both aerobics and muscle strength. Besides their placement in high schools, universities, and various kinds of commercial exercise facilities and gyms, weightlifting systems and sets also are found in private homes. Barbell weights are components of weightlifting equipment. So are dumbbells and kettlebells.

A barbell is a known kind of exercise equipment used in weight training, bodybuilding, weightlifting, and powerlifting, and normally consists of a long bar; in use, a barbell typically has weights attached at each end. A barbell has three main components: the bar or “shaft” of the barbell, the two sleeves—one on each end—and the bearings or bushings that connect the sleeves to the bar. The sleeves are slid onto each side of the bar. The bushings or bearings hold the sleeve on the bar; they also allow the sleeve to rotate and move independently of the shaft without falling off. The weights are placed near the distal ends of the sleeves.

Bearings are found in bars designed for Olympic lifting and are generally made of ball bearings, thrust bearings, or needle bearings. The bar extends all the way into the sleeves, and the sleeves are rotatable on the bar. The sleeves accordingly are the elements on the outer portions of the bar that hold the weight plates. On standard Olympic barbells the sleeves are 5 centimeters in diameter. This is important because nearly all weight plates are made to fit a standard bar.

Ordinary barbells in common use range in length from 1.2 meters to 2.2 meters. The central portion of the bar varies in diameter from 25 millimeters to 50 millimeters. This central segment often is engraved with a knurled crosshatch pattern to promote a solid grip by the weightlifting user. Various “weight plates” slide onto the outer portions of the bar to increase or decrease the desired total weight. Collars are releasably but securely attachable at appropriate locations on the barbell to prevent weight plates from moving unevenly, or from sliding off the barbell. A variety of exercises can be performed using the barbell, such as bicep curl, bench press, Olympic weightlifting, overhead press, deadlift, and squat. A standard Olympic barbell usually weighs about 20 kilograms.

More specifically, a men's Olympic bar is a metal bar that is 2.2 meters long and weighs 20 kilograms. The outer sleeves of a men's barbell are usually 50 mm in diameter, while the central, inner grip section or “shaft” is typically about 28 millimeters in diameter, and the center segment of the center bar (in between the two sleeves) is 1.31 meters in length. The sleeve diameter is important when building a weightlifting set, because nearly all weight plates have a central hole that fits a standard bar. These are the standards applied in competitive weightlifting where men and women compete at the highest level (e.g., the Commonwealth Games, Pan-American Games, World Championships, and the Olympics). Bars of this kind are required to have appropriate “whip,” that is, ability to flex to store elastic energy, and sleeves which rotate smoothly, as well as the capacity to withstand dropped lifts from overhead. A normal women's Olympic bar is similar to the men's bar, but is shorter (2.01 meters) and lighter (15 kilograms) with a relatively reduced grip section diameter of 25 millimeters.

In most lifts of a barbell, weight plates are disposed near each end of the bar, on the sleeves. The weight plates used in Olympic lifting, frequently called “bumper plates,” must be able to be safely dropped from above head height, and consequently are coated in shock-absorbing rubber. General strength training or powerlifting plates are typically made from cast iron. Weight plates used in Olympic lifting, frequently called “bumper,” plates, may also be cast iron, but are coated in solid rubber to make them safe to drop from above head height

Weight plates are commonly found in the following weights: 0.5 kg, 1.0 kg, 1.5 kg, 2.0 kg, 2.5 kg, 5.0 kg, 10 kg, 15 kg, 20 kg, and 25 kg. Various combinations of incremental weights of plates may be employed during a lift by a user, but the total weight lifted is to be safely divided equally and balanced on the ends of the barbell. Weight plates are commonly disk-shaped, with a central aperture through which the barbell is disposed during use. Olympic plates of 10 kilograms or more are about 450 millimeters in diameter. Lighter 5.0 kg and 2.5 kilograms versions of plates having 450 millimeter diameters also exist to accommodate the proper starting position for beginner athletes.

Many Olympic bars commonly encountered in commercial gyms and private homes, although superficially similar to standard Olympic bars, sometimes do not share International Weightlifting Federation (IWF) or powerlifting characteristics. They are simply generic strength training bars, with wide variations in markings, grip section diameter, and exact weight. Weight plates used outside of formal competition need not conform to IWF or powerlifting specifications. Standard collars for temporarily fixing the positions of the weight plates may be of any material, usually metal but also often plastic, and may weigh up to about 2.5 kilograms (normally less) each for both men and women's bars. Thus, a typical Olympic bar with a pair of collars, the plates not counted, can weigh as much as 25 kilograms for men and 20 kilograms for women depending on the collars. The barbell thus is a longer version of the “dumbbell” that is used for free weight training and in competitive sports.

Dumbbells are known in the art as weights used without exercise machines. Dumbbells are sometimes also called “free weights”—those used “free” of other equipment. Most dumbbells are designed with a narrow bar in the middle and two wider discs at each end. Some dumbbells are light in weight (only a kilogram or two) while others are relatively heavy (15 kg or more). Also, dumbbells can be fixed or variable in weight. Adjustable dumbbells can vary in weight due through the use of discs that can be added or removed from the bar by quantity and size (weight). Further, dumbbells can be used individually (a dumbbell in one hand) or in pairs (one in each hand). The purpose of dumbbells is to strengthen the body and to tone the muscles.

A kettlebell is a known type of free weight that is round with a flat base and an arch-like handle. A kettlebell looks somewhat like a cannonball with a handle, or a teapot without the spout (hence the name “kettlebell” in English). Kettlebells are usually made of either cast iron or steel. Unlike a dumbbell, a kettlebell's center of mass extends beyond the hand. Kettlebells can be swung, thrown, pressed, held, moved and manipulated in countless ways. They are small and portable, and may be incorporated into a variety of fitness training programs.

The storage and transportation of extensive (and expensive) sets or collections of weightlifting exercise equipment, including those discussed above, can pose a challenge. Moving a complete set or collection of weightlifting tools can be difficult due not only to the number of items to be moved, but also because of the total weight involved. If it is desired to store weightlifting equipment in one place, but to use it in another, transportation can discourage the use of the equipment. And it is normally desirable to store all the equipment in an organized manner, preferably in a comparatively small storage area.

Against the foregoing background, the presently disclosed exercise equipment storage and transportation system was developed.

SUMMARY OF THE DISCLOSURE

There is disclosed an apparatus and system for storing and transporting exercise equipment, particularly weightlifting equipment including barbells and weight plates, dumbbells, and kettlebells. The system is not so limited, as other kinds of exercise equipment may be disposed on the system. An object of the present invention is to provide a system that provides for rolled transport, and facile compact storage, of weightlifting equipment. An advantage of the present invention is that it is simple, and affordably manufactured. Another advantage of the present invention is that weight plates are used in the system as wheels for rolling transport of the system.

There is disclosed an exercise equipment storage and transport system for receiving barbells and weight plates. An embodiment of the system includes a front frame with two parallel horizontal front arms, each penetrated laterally by at least one front axle hole, and a front joining section that joins the front arms. This basic embodiment also has a rear frame with two parallel horizontal rear arms, each penetrated laterally by at least one rear axle hole, and a rear joining section that joins the rear arms. Means are provided for connecting the front joining section to the rear joining section. A first axle may be inserted through the front axle holes and a second axle may be inserted through the rear axle holes; when the first axle is inserted through the front axle holes, and when the second axle is inserted through the rear axle holes, at least one weight plate is disposed on each end of each axle to serve as a wheel upon which the frames may be rolled.

An extended embodiment of the system includes comprising the front frame and the rear frame, as well as an intermediate frame operatively situated between the front and rear frames. The intermediate frame has two parallel horizontal intermediate arms, each penetrated by at least one intermediate axle hole, an anterior joining section that joins the intermediate arms, and a posterior joining section that joins the intermediate arms. Means are provided for connecting the front joining section to the anterior joining section, and there also are means for connecting the rear joining section to the posterior joining section. A first axle may be inserted through the front axle holes and a second axle may be inserted through the rear axle holes. When the first axle is inserted through the front axle holes, and when the second axle is inserted through the rear axle holes, at least one weight plate is disposed on each end of each axle to serve as a wheel upon which the frames may be rolled.

Dumbbell and kettlebell carriers are removably mountable upon one or all the frames, whereby dumbbell and kettlebell sets can be transported by the rolling system, and stored in an orderly and compact manner thereon. In a basic embodiment of the system, a barbell may also be stored and transported on the system; an alternative extended embodiment permits one or two barbells to be stored and transported. Barbell weight plates are stored on the system as wheels, or on plate carrier rods mounted on the intermediate frame.

Other objects and advantages of the system, apparatus, and method of the present invention shall be apparent from the following specification.

Like elements are labelled with like numerals in the several views. The drawings are not necessarily to scale, either between views or within a single view.

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT

In the following detailed description, a preferred embodiment is described in sufficient detail so as to enable one skilled in the art to practice the invention. It is understood that other embodiments may be devised, and that logical, mechanical, material and various other assemblies may be made without departing from the scope of the present invention. The following description, therefore, is to disclose the invention but not necessarily to limit its scope.

It also should be understood that like or analogous elements and/or components, referred to herein, are identified throughout the drawings by like reference characters. In addition, it should be understood that the drawings are primarily symbolic and are only meant to aid in understanding the ideas and concepts disclosed. In the following disclosure and claims, “up,” “upward,” “down,” and “downward,” are used in conventional manners. “Up” and “down” and similar directional words thus can be presumed to be in relation to the direction of gravity. “Inward” and “outward” refer normally to radial directions toward or away from a central axis. “Horizontal” means parallel to the ground or floor, thus ordinarily perpendicular to the gravity vector.

There is disclosed herein an apparatus and system for storing and transporting exercise equipment, particularly a collection of weightlifting items or tools. The system is specially devised to store and transport barbells, dumbbells, and kettlebells, but is not so limited. The system may find utility in storing and moving other kinds of equipment as well. An advantage of the system is its versatility, as the number and kinds of weights that can be stored and transported is flexible and adjustable. Moreover, as described herein, a pair of axles and associated disk-shaped weight plates are readily incorporated into the system to function as a means upon which the system can be rolled. Specifically, two rigid rod-like axles can be engaged in the system, with associated weight plates rotatably disposed as wheels on the axles, so that the overall system can be transported by wheeling it across a supporting surface such the ground or floor.

FIG.1Aoffers a perspective view of an overall apparatus and system10according to the present invention. The basic embodiment of the system10is founded upon a fundamental frame assembly having a pair of frame members, a front frame14and a rear frame18. The combination of the front frame14and rear frame18as connected for use is shown inFIG.3. Seen inFIG.1Bis an intermediate frame22that optionally may be used to assemble an alternative, extended, frame assembly that includes three frame members, with the intermediate frame22connected between the front frame14and the rear frame18as illustrated simply inFIG.10.FIG.1Ashows generally that a plurality of round disk weight plates24,26,28,30are deployed as rolling wheels for the system10. The weight plates24,26,28,30are rotatably mounted upon and on the outsides of the front frame14and the rear frame18. In the preferred embodiment, a rod-like first axle32functions as a front axle for the wheels of the front weight plates24,26while a second axle34serves as the axle for the wheels of the rear weight plates28,30. Axles32and34are provided as elements of the system10, and preferably are fabricated from a durable, stiff metal alloy, for example steel. Referring still toFIG.1A, it is seen that the basic system10is assembled for use to store or transport various items of weightlifting equipment. Shown, by way of example, are six dumbbells15and a pair of kettlebells16removable placed upon the rear frame18and the front frame14, respectively, in a manner further to be described. Also seen inFIG.1Ais a barbell35stored vertically at the point where the front and rear frames14,18connect, also in a manner that is explained further herein. The system10according toFIG.1Acan be rolled across a supporting surface, typically a floor, to transport the various barbells, weight plates, dumbbells, and kettlebells—and other items a user may elect to place thereon—to and from a storage location.

FIG.2is another perspective view of the basic system10with certain equipment-holding components removed for clarity. The system10optionally may include a flexible pulling tether36removably connected to either of the front first axle32or the rear second axle34; inFIG.2the tether is depicted temporarily connected to the second axle34. Although not shown in the drawing, it is obvious that the tether36alternatively may be connected to the system at other places, such as by a harnessed connection to one of the frames14or18. The temporary connection may be by any suitable means, such as by clamping, tying, a tether collar that can be controllably opened/closed, or other means suited for temporarily connecting a flexible tether to an axle32,34, or one of the frames14,18. The pulling tether36may be a rope, cable, cord, lightweight chain, or other flexible line. The unconnected free end of the tether36optionally may be provided with a gripping handle (not shown) to facilitate a user's grasp of the tether. A user may pull manually upon the distal free end of the tether36to roll the system10across a supporting surface11such as a floor or an outdoor ground or concrete pad, or the like. Of course, rolling movement may be imparted to the system10by simply pushing directly upon one of the frames and/or the barbell35temporarily mounted vertically as seen inFIG.2.

Also seen inFIG.2are sled assemblies comprising a pair of sleds38,38′ and their associated sled brackets39,39′, removably attached to the end of the rear frame18. A pair of such sleds38,38′ can be employed in lieu of a pair of weight plate wheels, for example rear weight plates28,30. For example, if the rear weight plates28,30are removed from the rear frame18seen inFIG.2, the rear frame could be support by, and slid upon the supporting surface11, by the alternative means of the sleds38,38′ attached on the rear frame18by the brackets39,39′. The use of sleds38,38′ shall be disclosed in further detail hereinafter.

Attention is advanced toFIGS.5A and5B, which detail the configuration of the front frame14. The front frame14preferably is composed from a suitable strong, rigid material, such as a steel or aluminum alloy. The front frame14preferably is fabricated, as by welding or other permanent joinder means or method, so that its front arms42,42′ and front joining section44are permanently combined as a single, somewhat Y-shaped, “monobloc” in the sense of unitary or integral, rather than being temporarily assembled from separable elements. Preferably, the front frame14is fabricated from square metallic tubular box girders (e.g., for example about 10 cm each side in cross section). The front frame14preferably features two parallel horizontal front arms42,42′, each penetrated laterally by at least one front axle hole43,43′. The front frame14also includes a front joining section44that joins the front arms42,42′. As seen inFIGS.5A and5B, the front arms42,42′ have a plurality of top attachment apertures46defined serially along each of front arms42,42′ and vertically penetrating each front arm. Similarly, the front arms42,42′ also have a plurality of side attachment apertures47defined serially along each of the front arms42,42′ and laterally penetrating the sides of each front arm. Also seen inFIGS.5A and5Bis a first connector shaft48extending vertically upward from the front joining section44. The first connector shaft48preferably is a tube defining a cylindrical hollow interior49with a closed bottom (i.e., the top of the connector shaft interior49is open, but the interior is closed at or near the junction of the shaft with the front joining section44). The first connector shaft48is secured to or integral with the front joining section44. The functions of the first connector shaft48will be described hereinafter.

FIGS.6A-6Bshow the configuration of the rear frame18. Like the front frame, the rear frame18preferably is composed from a suitable strong, rigid material, normally a metal alloy. The rear frame18preferably is fabricated so that its rear arms52,52′ and rear joining section54also are combined as a single “monobloc.” Preferably, the rear frame18like the front frame14is fabricated from square tubular box girders. The rear frame18preferably features two parallel horizontal rear arms52,52′, each penetrated laterally by at least one rear axle hole53,53′. The rear frame18also includes its rear joining section54that joins the front arms52,52′. As seen inFIGS.6A and6B, the rear arms52,52′ have a plurality of top attachment apertures56defined serially along each of rear arms52,52′ and vertically penetrating each rear arm. Like the front arms, the rear arms52,52′ also have a plurality of side attachment apertures57defined serially along each of the rear arms52,52′ and laterally penetrating the sides of each rear arm. Also seen inFIGS.6A and6Bis a rear connector aperture58extending vertically through the rear joining section54. The rear connector aperture58preferably is a tube defining a cylindrical hollow interior59, and is secured to or integrally defined through the rear joining section54. The functions of the rear connector aperture58will be further described.

FIG.3illustrates further the assembly and configuration of the fundamental frames of the system10. The basic frame assembly includes the front frame14which in turn has the parallel horizontal front arms42,42′ penetrated laterally by at least one front axle hole43,43′. The front joining section44joins the front arms and holds them in spaced relation. The rear frame18has the parallel horizontal rear arms52,52′, each penetrated laterally by at least one rear axle hole53′53′. The rear joining section54joins the rear arms52,52′.FIG.3also illustrates that the first connector shaft48and the rear connector aperture58are operative engageable to serve as a means for connecting the front joining section44to the rear joining section54. As the first connector shaft48extends vertically upward from the front joining section44, and the rear connector aperture58is defined vertically through the rear joining section54, the first connector shaft is disposable upward through the rear connector aperture, thereby to pivotally connect the front frame14to the rear frame18. The outside diameter of the first connector shaft48preferably is just less than the diameter of the rear connector aperture58so that that the shaft48slides through the aperture58with little gap between them. When thus interconnected, the two frames14,18are yoked together, yet pivotal relative to one another in the horizontal plane as suggested by the directional arrows inFIG.3. There is provided, however, a locking flange62extending securely from the rear joining section54adjacent the rear connector aperture58(see alsoFIGS.6A-B), which in combination with a locking hole63(FIGS.5A-B) in the front joining section44, permits the two frames14,18to be selectively and temporarily locked against relative pivotal movement.

Attention is invited toFIGS.3and4in combination, showing an assembly of the basic embodiment of the system10. The use of rod-like axles and disk weight plates as the axles and wheels for a rollably movable system are illustrated. As illustrated inFIG.4, the first axle32is slidably inserted through the front axle holes43,43′ and the second axle34is insertable through the rear axle holes53,53. While four axle holes43,43′ and53,53′ are illustrated, it is to be understood that more than four axles holes may be defined through the arms of the frames14and18; the number of axle holes in any pair of arms42,42′ or52,52′ may be increased to improve the versatility or adaptability of the system10. The two illustrated front axle holes43and43′ are aligned laterally, so that when inserted the first axle32is generally perpendicular to both the front arms42,42′. Similarly, the rear axle holes53,53′ are aligned laterally, so that when inserted the second axle34is generally perpendicular to the rear arms52,52′.

As seen also inFIGS.1-2, at least one weight plate is disposed on each end of each axle32,34to serve as a wheel upon which the frames14,18(and thus the system10) may be rolled. For simplicity of illustrationFIG.4shows only several left front weight plates24and the several left rear weight plates30, while full complements of weight plates24,26,28and30are seen inFIGS.1and2. The number of weight plates disposed near the end of each axle is at least one, but can be more. The plates disposed at an end of a particular axle also can be of differing diameters (in which instance the weight plate of greatest diameter functions effectively as the wheel). Thus, a significant number (e.g., 4-16) weight plates24,26,28and30may be transported and stored upon the axles32,34according to the invention. Preferably, of course, the number, types, and arrangement of weight plates is symmetrical upon the ends of a given axle.

FIG.4also shows that conventional barbell collars66(e.g., lever-locking barbell collars) potentially may be used to secure the weight plates24,26,28and30at the ends of the axles32,34, on the outsides of the respective arms42,42′,52,52′ of respective frames14,18. Alternative equivalent types of removable collars, not barbell collars, may suitably be devised and provided for the security of the weight plates upon the ends of the axles. Collars66may be removably secured to the axles32,34, by spring bar clips, or screw-type pins, or the like, according to convention. Consequently, as assembled according toFIGS.1-2and4, two axles32,34and at least four weight plates24,26,28and30can not only be stored in the system10, but also may serve as the means by which the overall system may be transported by being rolled across the supporting surface11.

As seen inFIGS.1-4, a beneficial feature of the system10is that a barbell35may be stored and moved in the system10. The barbell35optionally may be vertically stored and transported in the system by being slidably and removably inserted into the hollow interior49of the front connector shaft48. The hollow interior49defines a diameter that is modestly greater than the standard diameter of an end of a conventional barbell. Thus in a preferred embodiment of the system10, the first connector shaft48is a hollow tube adapted to receive an end of any barbell such as barbell35. The barbell35is simply dropped into the first connector shaft48until the bottom end of the barbell35contacts the closed bottom of the shaft interior49. The third barbell so stored may readily be withdrawn from the shaft48for use.

Combined reference toFIGS.3,4,5A-B and6A-B further illustrates how the first connector shaft48and the rear connector aperture58serve as the means for connecting the front joining section44to the rear joining section54. Because the first connector shaft48is disposable upward through the rear connector aperture58, the front frame14is pivotally connectable to the rear frame18. Such pivotal movement, when freely permitted by a user, fosters the steerability of the system10while it is being rolled.

The frames14,18can, however, be selectively locked against mutual rotation or pivotal movement.FIG.3throughFIGS.6A-Bshow that there is defined in a top surface of the front joining section44at least one front locking hole63, which may be threaded to receive a locking screw or bolt64. The locking flange62extends securely from the rear joining section54of the rear frame18. Locking flange62is fully penetrated by at least one locking bolt hole65, which also may be threaded for screwed engagement with the locking bolt64. As indicated byFIGS.3-4, when it is desired to prevent pivotal motion by either of the frames14,18, the rear frame18may be pivoted into a locking position relative to the front frame14, in which the locking hole63and the locking bolt hole65are brought into vertical registration. With the locking hole63aligned with the locking bolt hole65, the bottom of the locking flange62is placed against the top surface of the front joining section44, and the locking bolt64is inserted (e.g., screwed) though the locking hole63and locking bolt hole65. With the locking bolt64engaged through both holes63,65, the frames14,18are prevented from pivotal movement relative to one another. Thus, means for releasably locking the rear frame18against pivotal movement relative to the front frame14include the locking flange62, the locking holes63,65, and the locking bolt64. A person skilled in the art recognizes that the bolt64alternatively could be an unthreaded pin or rod; other equivalent locking means are readily contemplated.

The system includes auxiliary components for facilitating the storage of exercise equipment upon one or both the frames14,18.FIG.8depicts a dumbbell carrier70useable in the present invention. The dumbbell carrier70has a dumbbell rack72with at least two, and preferably a plurality, of upward facing notches therein. At least two notches73,73′ are defined in the rack72with the notches73,73′ aligned laterally to receive therein the central rod or grip portion of a dumbbell. One or more additional pairs of notches74,74′ preferably are provided in the top of the rack72, in parallel relation to the first pair of notches73,73′, to accept and hold additional dumbbells. The dumbbell carrier70includes two or more, preferably four, mounting flanges76on or extending outward from the rack72. Each mounting flange75is completely penetrated by at least one carrier mounting hole77. The flanges75and carrier mounting holes are useable for mounting the dumbbell rack70on the top of either one, or both, of the frames14,18. To removably and adjustably mount the dumbbell carrier70to a frame14,18, the mounting holes77of the carrier are simply aligned with any of the top attachment apertures46,56, and pins, screws, bolts or rods (not shown) inserted through respective aligned holes temporarily to position and secure the carrier70to a frame.

Accordingly, having combined reference toFIGS.3and8, it is seen that the dumbbell carrier70can be placed upon either, or both, of the frames14,18with the carrier flanges75upon the tops of corresponding ones of the front arms42,42′ and/or rear arms52,52′. Further, the dumbbell rack72, and its flanges75and mounting holes77, are configured so that at least two, preferably four, carrier mounting holes can be placed in registration with two (or four) associated top attachment apertures46(in front arms42,42′) or with two (or four) top attachment apertures56(in the rear arms52,52′). With each carrier mounting hole77aligned with a top attachment aperture46or56, screws, bolts, pins or other suitable attachment means may be inserted through the carrier mounting holes in the flanges76and into the top attachment apertures46or56to removably mount the carrier70to frame14or18. In view of the foregoing, particular reference may be made toFIG.1A, showing a dumbbell carrier70removably mounted on the horizontal rear arms52of the rear frame18; a plurality of upward notches73,73′,74,74′ in the carrier70hold, inFIG.1A, six dumbbells15in parallel. Referring toFIGS.1and3, although not specifically illustrated, it is apparent to one skilled in the art that a second dumbbell carrier70likewise could be removably mountable on the horizontal front arms42,42′ to similarly hold one or more dumbbells15in the manner ofFIG.1A, so that two dumbbell carriers70are deployed for use. Further, the system may be devised to permit two or more dumbbell carriers to be stacked vertically on either of the frames14and/or18.

FIG.9depicts an auxiliary assembly of the system10by which kettlebells16(FIG.1A) may be transported and/or stored. There is provided according to the present invention at least one kettlebell carrier80with a kettlebell bracket82, and a kettlebell carrier cap84. As indicated inFIG.1A, the assembly of a kettlebell carrier80, kettlebell bracket82, and a kettlebell carrier cap84is engageable with an open end86of any of the front arms42,42′ (or the open end86of any of the rear arms52,52′) of the respective frames14and18. The kettlebell carrier80and kettlebell bracket82are composed from any rigid durable material, and may be plastic or metal, while the kettlebell carrier cap84preferably is fabricated to be resiliently elastic, as out of a flexible rubber or polymer. The base of the kettlebell carrier80has at least one pin hole81defined therein, as in its upper or top surface. A kettlebell carrier rod87extends (e.g., axially) from the main base of the carrier80. As seen in the drawing figures, the kettlebell carrier rod87may define therein a pair of angles (e.g., two 90-degree angles) so to elevate an upper segment of the rod a sufficient height above the supporting surface11to provide vertical clearance for the carriage of a kettlebell above the supporting surface. There is defined horizontally, axially, through the kettlebell bracket88a kettlebell bracket mounting hole85.

As suggested byFIG.9, the kettlebell bracket82is slidably but reasonably snuggly engageable on and around the kettlebell carrier rod87. The carrier rod87preferably is configured with two perpendicular bends therein, so to define a lower segment, a vertical segment, and an upper segment. Such a configuration provides that, when the kettlebell carrier80is engaged with an open end of any of the front arms42,42′or of the rear arms52,52′, the upper segment is spaced a sufficient distance from the floor or other supporting surface to permit the largest of kettlebells16to be suspended above the supporting surface. With the kettlebell bracket82fully disposed along upon the kettlebell carrier rod87(e.g., the upper segment of the carrier rod), the kettlebell carrier cap84, which has a flexibly adaptable socket (not shown) on one side, is securely but removably engaged upon the distal or “free” end of the kettlebell carrier rod87, thereby to hold the bracket82against inadvertent detachment from the carrier rod. Each kettlebell bracket82has a groove or channel88defined in its top, adapted to receive the underside of a handle of a typical kettlebell (FIG.1A).

Referring now, for example, toFIG.5A, a free end (opposite the front joining section44) of at least one of the front arms42,42′ defines a receptacle opening86therein. Although not shown inFIG.6A, a free end (opposite the rear joining section52) of at least one of the rear arms52,52′ likewise defines a receptacle opening86therein. The exterior dimensions and contours of the base of the kettlebell carrier80are complementary to the interior dimensions and contours of any receptacle opening86.

Combined attention is returned toFIG.1andFIG.4. A kettlebell carrier80accordingly is removably insertable horizontally into a receptacle opening86in any one or more of the ends of the arms42,42′, or52,52′ of the frames14and/or18, with its kettlebell carrier rod87distending outward from the associated frame arm. The kettlebell bracket82is slidably engaged on the kettlebell carrier rod87, and the bracket is adapted for receiving a kettlebell16thereupon (as seen inFIG.1). The installed base of the kettlebell carrier80projects into the interior of the corresponding receptacle opening86. As seen inFIG.1A, a screw, pin, bolt or rod preferably may be temporarily inserted through a selected top attachment aperture46or56and into the co-aligned the carrier pin hole81of the kettlebell carrier80, thereby to removably secure the kettlebell carrier within the receptacle opening86. Alternatively, an embodiment may be devised in which the kettlebell carrier80has its one or more carrier pin holes81defined in its side; in such an alternative, a screw, pin, bolt or rod preferably may be temporarily inserted through a selected side attachment aperture47or57and into the co-aligned the carrier pin hole81of the kettlebell carrier80. It is immediately understood that in the system10more than one (i.e., up to four) assembly (two seen inFIG.1A) for receiving a kettlebell16may be provided and deployed, one assembly for each of the receptacle openings86in each of the horizontal arms42,42′, or52,52′.

Attention is invited toFIGS.2and11. A system according to the invention optionally includes the use of sled assemblies (including sleds and sled brackets) instead of weight plate wheels, to support and move the system across a supporting surface11. As disclosed previously, an end of at least one of, preferably both, the front arms42,42′ and/or an end of at least one, preferably both, the rear arms52,52′ defines a receptacle opening86. The system10optionally includes a sled brackets39,39′ removably insertable horizontally into a corresponding receptacle opening86, and sleds38,38′ engageable with a corresponding sled bracket39or39′. Sleds38,38′ and sled brackets39,39′ are composed of any rigid durable material, preferably metal alloy, and may include segments of tubular box girder. A single exemplary sled38is depicted byFIG.11. A sled38according to the invention has a generally planar runner92with an optional shortly upturned front lip93, a familiar configuration for ski tips and the runners of sleds and sleighs. Integral with, and extending vertically upward from, the runner92is the sled stanchion94. The stanchion94has a series of vertically aligned pin holes95defined through its lateral sides.

A given sled38includes a vertical stanchion94slidably adjustable in, and relative to, the sled bracket39, and a horizontal sled runner92at the bottom of the stanchion94. Any one or more, preferably two or four, of the receptacle openings86in a system10may be used to receive and engage with a sled bracket39and its associated sled38.

As suggested inFIG.2, a sled bracket39has a horizontal portion whose exterior dimensions and contour are complimentary with the interior dimensions of a receptacle opening86; accordingly the sled bracket horizontal portion is slidably, yet securely but removably, insertable into a receptacle opening86in a manner like that illustrated for the kettlebell carrier80inFIG.4. The sled bracket's horizontal portion has at least one, preferably a plurality, of pin holes defined in and along its top. A screw, pin, or equivalent means preferably may be temporarily inserted through a selected top attachment aperture46or56and into a co-aligned the pin hole in the top of the sled bracket39, thereby to removably secure the sled bracket within a receptacle opening86. Alternatively, the bracket pin holes may be defined in the lateral sides of the brackets39,39′, and a screw, pin, or equivalent temporarily inserted through a selected side attachment aperture47or57and into a co-aligned the pin hole in the side of the bracket to removably secure the sled bracket within a receptacle opening86.

A sled bracket39also has a hollow vertical portion integrally connected thereto in perpendicular relation therewith. This hollow vertical portion has at least one, preferably a plurality, of vertically aligned pin holes defined through and along its sides. The exterior dimensions and contour of the sled stanchion94are complementary to the interior dimensions and shape of the hollow interior of the vertical portion of the sled bracket39. Referring to bothFIG.2andFIG.11, the vertical sled stanchion94thus is slidably insertable/removable into/from the hollow vertical portion of the sled bracket39. The position of the stanchion94within the hollow vertical portion of the sled bracket39consequently is selectively adjustable, as the stanchion can be moved manually up/down within the sled bracket39in a regulated manner. As suggested byFIG.2, a screw, pin, rod, or the like may be temporarily inserted through a selected one of the pin holes in the side(s) of the vertical portion of the sled bracket39and into a co-aligned the pin hole95in the side(s) of the stanchion94, thereby to temporarily secure the stanchion within the hollow vertical portion of the sled bracket39. It is seen therefore, that the vertical location of a sled runner92, relative to a frame14or18, is adjustable by a user; this by the expedient of positioning the stanchion94at the desired elevation in the sled bracket39, and choosing appropriately aligned ones of the pin holes, in the vertical portion of the sled bracket and the stanchion, through which to insert the locking screw, pin, or rod.

Referring toFIG.2, it is apparent therefore that a sled assembly including a sled38and sled bracket39, is optionally useable in lieu of a weight plate “wheel” (24,26,28, or30) to support either or both of the frames14,18upon the supporting surface11. Sleds and sled brackets normally are used in pairs. InFIG.2, for example, a pair of sleds38,38′ and an associated pair of sled brackets39,39′ are engaged in the receptacle openings86of a rear frame18. With the elevations of the sleds38,38′ properly (normally evenly and equally) adjusted within the sled brackets39,39′ and temporarily secured therein, the second axle34and rear weight plate wheels28,30could be removed from the rear frame18. The rear frame18would then be supported by the sleds38,38′, whose runners92then rest slidably upon the supporting surface11.

The pulling tether36, attached for example to the second axle34, may then be used manually to pull the system10across the supporting surface. The increased friction between the supporting surface11and the sleds38,38′ increases the manual force needed to move the system10across the supporting surface, thus increasing a “workout” by the user if desired. Although only two sleds38,38′ and two sled brackets39,39′ are seen in the drawing, it is readily understood that two additional sleds and associated sled brackets optionally could also be inserted and temporarily secured, if desired, in the respective receptacle openings86in the arms42,42′ of the front frame14inFIG.2. In such instance, both the frames14and18would be supported by sleds, and the system10could be moved only by sliding—rather than rolling—across the supporting surface, to provide a pulling exercise for a user.

A more extensive, alternative embodiment of the system10incorporates the use of the intermediate frame22(FIG.1B) disposed between, and interconnected with, the front frame14and the rear frame18. The inclusion of an intermediate frame increases the versatility of the system and its capacity to receive, hold, and store exercise equipment.

The intermediate frame22seen inFIG.1Bis depicted in more detail byFIG.7AandFIG.7B. The intermediate frame22preferably is composed from a suitable strong, rigid material, such as a metal alloy. Like the other frames14,18, the intermediate frame22preferably is fabricated, as by welding of tubular square box girders, so that its intermediate arms100,100′ and joining sections102,103are permanently combined as a single monobloc. The intermediate frame22includes two parallel horizontal intermediate arms100,100′, each penetrated by at least one intermediate axle hole101,101′. An anterior joining section102joins two ends of the intermediate arms100,100′, and a posterior joining section103joins the other two ends of the intermediate arms.

Also like the other frames14,18, the intermediate arms100,100′ have a plurality of middle top attachment apertures104defined serially along each of the intermediate arms, and vertically penetrating each arm. Similarly, the intermediate arms100,100′ also have a plurality of middle side attachment apertures105defined serially along each of the intermediate arms, and laterally penetrating the sides of each arm. Also seen inFIGS.7A and7Bis a second connector shaft108extending vertically upward from the posterior joining section103. The second connector shaft108preferably is a tube defining a cylindrical hollow interior109with a closed bottom (i.e., the top of the second connector shaft interior109is open, but the interior is closed at or near the junction of the shaft108with the posterior joining section103). The second connector shaft108is secured to or integral with the posterior joining section103.

Also seen inFIGS.7A and7Bis an intermediate connector aperture112extending vertically through the anterior joining section102. The intermediate connector aperture112preferably is a tube defining a cylindrical hollow interior113, and is secured to or integrally defined through the anterior joining section102. The intermediate connector aperture112is engageable with the first connector shaft48on the first frame14, so to connect the intermediate frame22to the front frame14in effectively the same manner as the rear connector aperture58is engageable with the first connector shaft48to connect together the front frame14and rear frame18as described hereinabove (FIGS.3and4). Similarly, the second connector shaft108on the intermediate frame22is engageable with the rear connector aperture58on the rear frame18to connect the intermediate frame22to the rear frame18in effectively the same manner as the rear connector aperture58is engageable with the first connector shaft48to connect together the front frame14and rear frame18. The extended embodiment of the system is understood, therefore, to include three serially interconnected frames, i.e., the intermediate frame22situated between the front frame14and the rear frame18, as illustrated inFIG.10.

ConsideringFIG.10in the context of the previous discussion of the operative connection between front frame14and rear frame18promotes a full understanding of the extended embodiment of the system10. The second connector shaft108and the rear connector aperture58are operative engageable to serve as a means for connecting the intermediate frame's posterior joining section103to the rear joining section54of the rear frame18. As the second connector shaft108extends vertically upward from the posterior joining section103, and with the rear connector aperture58defined vertically through the rear joining section54, the second connector shaft is disposable upward through the rear connector aperture, thereby to pivotally connect the rear frame18to the intermediate frame22. When thus interconnected, the two frames18,22are yoked together, yet pivotal relative to one another in the horizontal plane. However, the locking flange62extending from the rear joining section54adjacent the rear connector aperture58, in combination with an intermediate locking hole115(FIGS.7A-B) in the posterior joining section103, permits the two frames18,22to be selectively and temporarily locked against relative pivotal movement in the same mode and means as previously described herein (FIG.4) respecting the front and rear frames14,18.

Similarly, the first connector shaft48and the intermediate connector aperture112are operative engageable to serve as a means for connecting the intermediate frame's anterior joining section102to the front joining section44of the front frame14. As the first connector shaft48extends vertically upward from the front joining section44, and with the intermediate connector aperture112extending vertically through the intermediate frame's anterior joining section102, the first connector shaft is disposable upward through the intermediate connector aperture112, thereby to pivotally connect the front frame14to the intermediate frame22. When thus interconnected, the two frames14,22are yoked together, yet pivotal relative to one another in the horizontal plane. But again, the intermediate locking flange114(with fastener hole111defined there-through) extending from the anterior joining section102adjacent the intermediate connector aperture112, in combination with the locking hole63(FIGS.5A-B) in the front joining section44, permits the two frames14,22to be selectively and temporarily locked against relative pivotal movement (as with a locking rod or bolt) in the same mode and means as previously described herein respecting the interconnection of the front and rear frames14,18. A user may selectively unlock the interconnection between any two frames ((14and22) and/or (22and18) to permit relative pivotal motion, thereby facilitating the steering of the entire system while it is being wheeled across a supporting system. When the system has arrived at a location (e.g., storage), the frames14,22, and18can be locked against swiveling motion.

The extended embodiment of the system10according toFIG.10otherwise is similar to, and functions similarly, to the basic system embodiment ofFIGS.1-3. The alternative extended embodiment according toFIG.10also is an exercise equipment storage and transport system for receiving at least two axles with at least one weight plate disposable on each end of each axle. It features the front frame14including two parallel horizontal front arms42,42′, each penetrated laterally by one or more front axle holes43,43′, and the front joining section44that joins the front arms. The alternative extended embodiment also features the rear frame18with two parallel horizontal rear arms5252′, each penetrated laterally by one or more rear axle holes53′,53′, with the rear joining section54that joins the rear arms. But the extended embodiment also incorporates the intermediate frame22having its two parallel horizontal intermediate arms100,100′, each penetrated by one or more intermediate axle holes101,101′. The intermediate frame22includes two joining sections at opposite ends thereof, namely the anterior joining section102that joins the intermediate arms and the posterior joining section103which also joins the intermediate arms.

The extended embodiment according toFIG.10includes means for connecting the front joining section44to the anterior joining section102, and means for connecting the rear joining section54to the posterior joining section103. As described above, the means for connecting the front joining section44of the first frame to the anterior joining section102of the intermediate frame includes the first connector shaft48extending vertically upward from the front joining section, and the intermediate connector aperture112extending vertically through the anterior joining section102; the first connector shaft48is disposable upward through the intermediate connector aperture112to pivotally connect the front frame14to the intermediate frame22.

The alternative embodiment ofFIG.10also has means for connecting the rear joining section54of the rear frame18to the posterior joining section103of the intermediate frame22. Such means for connecting includes the second connector shaft108extending vertically upward from the posterior joining section103, and the rear connector aperture58extending vertically through the rear joining section54; the second connector shaft108is disposable upward through the rear connector aperture to pivotally connect the intermediate frame to the rear frame.

It is readily apparent to a person of ordinary skill that the extended embodiment of the system, incorporating the three-part frames ofFIG.10, is used and functions quite similarly to the basic embodiment seen in, for example,FIG.2. The extended embodiment is simply longer from front to back, with the front frame14connected to the intermediate frame22, and the intermediate frame22connected to the rear frame18. The connections initially are pivotal, but both connections can be releasably locked as described hereinabove to bar any frame against pivotal movement relative to an adjacent frame. Pivotal movement may be undesirable, for example, while the system10is being used solely to store equipment. Either or both connections between the respective frames14,18,22can, however, be unlocked so that two or all three frames can swing or pivot horizontally; such pivotal movement, which may be through, for example from zero to about 100 degrees about the pivotal axis, permits the direction of movement of the system10to be controllably steered while when the system is rolling/sliding across a supporting surface.

Considered in the context of the full disclosure herein, it is apparent that the intermediate frame22when included in the system functions and serves quite similarly to either of the front or rear frames18. Referring toFIGS.1B,7A,7B, and8, it is apparent, for example, that a dumbbell carrier70may be releasably and adjustably mounted upon the top of the intermediate frame22by the means of pins, screws, or rods inserted through carrier mounting holes77co-aligned with respective ones of the middle top attachment apertures104in the intermediate frame. Accordingly, the extended alternative embodiment of the system option may mount one, two or three dumbbell carriers70.

A functional aspect unique to the extended embodiment ofFIG.10is now described. Referring to bothFIG.1BandFIG.12, one or two plate carrier rods117are provided for use in combination with the intermediate frame22. Each plate carrier rod117may be inserted removably but securely into either or both the intermediate axle holes101,101′ of the intermediate frame22. (Temporary security may be provided by, for example a cotter pin (not shown) engaged through a hole (not shown) in the carrier rod117, or by any other suitable equivalent means). With one or two plate carrier rods117disposed in the intermediate axle holes101and/or101′ one or more weight plates may be slidably and rotatably disposed onto the laterally extending carrier rod(s) (FIG.1B) for transport and storage. Weight plates may be beneficially placed upon one or two a pair of carrier rods117in the intermediate frame22when, for example, sled assemblies (38,38′,39,39′) are deployed for use in one or both of the other frames14,18. Further, it is apparent to one skilled in the art that, in lieu of one or two carrier rods117, a single rod (e.g., axle32or34) may be inserted through the intermediate axle holes101,101′, and weight plates (e.g.,28,30) rotatably disposed on opposite ends thereof, to provide an axle and wheels on the intermediate frame22in use on the extended alternative embodiment of the system10. Such a deployment may be executed with either or both of the other frames14,18also having wheeled support or sled-type support on the supporting surface.

Reference toFIG.10also discloses that the extended alternative embodiment of the system10permits one, or two, barbells to be vertically transported or stored on the system. A barbell may be removably into the interior49of the first connector shaft48, and/or another barbell may be removable inserted into the interior109of the second connector shaft108.

The overall system10also can be used to hold and store other equipment, including gloves and clothing, or the like, for example which may be hung upon the barbells35. Further, pins or rods may be inserted into any ones of the top or side apertures46,47,56,57,104,105, and employed to hang or attach items to the system.

Although the invention has been described in detail with particular reference to these preferred embodiments, other embodiments can achieve the same results. In the previous description, specific details are set forth, such as specific materials, structures, dimensions, etc., in order to provide a thorough understanding of the present invention. However, as one having ordinary skill in the art would recognize, the present invention can be practiced without resorting to the details specifically set forth.

Only some embodiments of the invention and but a few examples of its versatility are described in the present disclosure. It is understood that the invention is capable of use in various other combinations and is capable of changes or modifications within the scope of the inventive concept as expressed herein. Modifications of the invention will be obvious to those skilled in the art and it is intended to cover in the appended claims all such modifications and equivalents.
