## Background
FIELD OF THE INVENTION
The subject invention relates to exercise methods and apparatus, and more specifically, to dumbbell stands and dumbbell stands combined with dumbbells to provide exercise systems.
BACKGROUND OF THE INVENTION
Various types of exercise equipment are known in the art. One popular form of equipment is the exercise dumbbell, which is typically designed with one or more weights disposed at each end of a handle. Relatively more advanced dumbbell systems provide a plurality of weights in alignment with the handle for selective connection to the handle. Examples of such systems are disclosed in U.S. Pat. No. 4,822,034 to Shields; U.S. Pat. No. 4,284,463 to Shields; U.S. Pat. No. 5,637,064 to Olson et al.; U.S. Pat. No. 5,769,762 to Towley, III et al.; and U.S. Pat. No. 5,839,997 to Roth et al. An object of the present invention is to provide methods and apparatus for supporting exercise dumbbells in user friendly fashion, and/or supporting selectorized dumbbell weight plates that remain behind when the handles are lifted.
SUMMARY OF THE INVENTION
The present invention provides methods and apparatus for providing support for dumbbells. For example, the present invention may be described in terms of a dumbbell stand for supporting a pair of exercise dumbbells above a floor surface, comprising first and second dumbbell supports, each having a leg portion configured and arranged to engage the floor surface, and a beam portion configured and arranged to support a respective dumbbell. The dumbbell supports are interconnected for relative pivoting about at least one vertical axis to define a first configuration, wherein a first horizontal distance is defined between the leg portions, and to alternatively define a second configuration, wherein a second, relatively greater horizontal distance is defined between the leg portions.
The present invention may also be described in terms of a dumbbell stand for supporting a pair of exercise dumbbells above a floor surface, comprising a first dumbbell support configured and arranged to support a first dumbbell; a second dumbbell support configured and arranged to support a second dumbbell; a base configured and arranged to engage the floor surface; an accessory tray mounted on the base; and a connecting means for connecting each said dumbbell support to the base in a manner that accommodates user adjustment of a distance defined between opposing counterparts on the first dumbbell support and the second dumbbell support. The dumbbell supports occupy a space directly forward of the tray when a first distance is defined between the opposing counterparts, and the space is available to accommodate a standing person when a relatively greater, second distance is defined between the opposing counterparts.
The present invention may also be described in terms of a dumbbell stand for supporting a pair of exercise dumbbells above a floor surface, comprising first and second dumbbell supports, each having a leg portion configured and arranged to engage the floor surface, and a beam portion configured and arranged to support a respective dumbbell; a base configured and arranged to engage the floor surface; and a connecting means for connecting each said dumbbell support to the base in a manner that accommodates arcuate movement across the floor surface of at least one said leg portion relative to the base.
The present invention may also be described in terms of a dumbbell stand for supporting a pair of exercise dumbbells above a floor surface, comprising a base having opposite end portions configured and arranged to engage the floor surface; first and second dumbbell supports, each having a leg portion configured and arranged to engage the floor surface, and a beam portion configured and arranged to support a respective dumbbell, and movably connected to the base.
The stands may be provided with floor engaging rollers to facilitate rolling across an underlying floor surface. Also, certain features of the different embodiments may be mixed, matched, and/or applied to other embodiments. For example, various accessory trays may be used on various stands to provide upwardly opening compartments for holding items along the lines of a beverage container, jewelry, keys, a note pad, and/or a remote control device for radio, television, and the like.
In a preferred application, the stand is configured to support first and second selectorized dumbbell assemblies, each of which includes (a) a handle that defines a longitudinal axis; (b) a set of weights configured for connection to a respective said handle; and (c) a base that is sized and configured to support a respective said set of weights in alignment with a respective said handle. Each such base is mounted on a respective dumbbell support. Various features and/or advantages of the present invention may become apparent from the more detailed description that follows.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
A first exercise system constructed according to the principles of the present invention is designated as 100 in FIGS. 1–5. The system 100 may be described in terms of a pair of known selectorized dumbbells 90a and 90b disposed on a novel dumbbell stand.
The dumbbells 90a and 90b are shown somewhat diagrammatically because their particular construction and operation are already known in the art, and are not critical to understanding the present invention. For purposes of this disclosure, the dumbbells 90a and 90b should be considered identical to those disclosed in U.S. Pat. No. 5,839,997 to Roth et al. (which is incorporated herein by reference), with the understanding that the present invention is not limited to this particular dumbbell or type of dumbbell.
Generally speaking, each dumbbell 90a and 90b includes a handle member and a plurality of weight plates that are selectively connected to a respective handle member. A weight base or cradle 129a and 129b is provided for each dumbbell 90a and 90b to support the weight plates in proper alignment when not in use. Each cradle 129a and 129b is approximately twelve inches long and six inches wide. The cradles 129a and 129b are similar to those disclosed in the Roth et al. patent, except to the extent that they have been modified for mounting on respective first and second dumbbell supports 120a and 120b. In this regard, each cradle 129a and 129b is preferably provided with a partially cylindrical channel that registers with a respective dumbbell support 120a or 120b, and is fastened in place by bolts (not shown) or other suitable means.
Each dumbbell support 120a and 120b may be alternatively described as a generally L-shaped member having a vertically extending leg portion that is supported by an underlying floor surface, and a horizontally extending beam portion that supports a respective dumbbell 90a or 90b, and is connected (by suitable connecting means) to a respective side of an intermediate frame member or support frame 110. Each leg portion terminates in a lower distal end, to which a respective caster-type roller 128a and 128b is preferably rotatably mounted. Each beam portion terminates in a distal end that is rigidly connected to a respective sleeve 121a or 121b by welding or other suitable means. The dumbbell supports 120a and 120b are preferably configured and arranged to position the handles of the dumbbells 90a and 90b at approximately table height above the floor.
The intermediate frame member 110 may be described as an inverted U-shaped member having first and second downwardly extending legs or shafts. Caster-type rollers 118a and 118b are rotatably mounted on the lower distal ends of respective legs. Each sleeve 121a and 121b is rotatably mounted on a respective leg of the intermediate frame member 110 for rotation about a respective vertical axis. On the depicted embodiment 100, respective lower collars 111a and 111b and upper collars 112a and 112b are secured to the respective legs of the intermediate frame member 110 (by set screws or other suitable means) to prevent translational movement of the sleeves 121a and 121b. The collars are also preferably configured to function as bushings between the legs of the intermediate frame member 110 and the sleeves 121a and 121b. The collars may also be provided with radially extending flanges to facilitate biasing and/or latching of respective beams portions relative thereto.
A tray 140 is mounted on the intermediate frame member 110 to provide upwardly opening compartments for storage of personal items. For example, the depicted tray 140 provides a cylindrical compartment 143 to support a typical beverage container; shallow square compartments 144a and 144b to store jewelry, a note pad, or other suitably sized items; a relatively deeper first compartment 145 to store a hand-held remote control device, a folded magazine, or other suitably sized items; and a relatively deeper second compartment 146 to store a portable CD player, one end of a towel, or other suitably sized items. On the depicted embodiment 100, the tray 140 slides onto the legs of the intermediate frame member 110 (before the sleeves 121a and 121b) and is bolted to the transverse portion of the intermediate frame member 110. In the alternative, a relatively smaller tray could simply be suspended from a central portion of the transverse portion or horizontal cross-bar.
The tray 140 also may be configured to provide stops and/or means for latching the dumbbell supports 120a and 120b in prescribed orientations. For example, FIG. 4 shows downwardly extending tabs 142a and 142b on respective sides of the tray 140. In FIG. 4, the dumbbell supports 120a and 120b are disposed “inward” of respective tabs 142a and 142b, and the adjacent arcuate notches in the tray 140 define the respective “outward” ends of the tabs 142a and 142b. In FIG. 1, the dumbbell supports 120a and 120b are disposed “outward” of respective tabs 142a and 142b. The tabs 142a and 142b resiliently deflect to accommodate movement of the dumbbell supports 120a and 120b between these two configurations.
Those skilled in the art will recognize that the stand shown in FIGS. 1–5 may be constructed without the tray 140 and/or without the associated latching means. For example, in the absence of tray 140, the dumbbell supports 120a and 120b could be left free to pivot subject to frictional resistance, or spring detents could be imposed between the support frame 110 and the supports 120a and 120b to establish latched positions. Also, in the absence of tray 140, a water bottle holder could be mounted on any of the frame members 110, 120a, or 120b, and/or the transverse portion of the intermediate frame member 110 could serve as a towel bar.
As suggested by FIGS. 1–2 and 5–6, the stand (with or without the tray 140) may be rearranged or transformed into multiple configurations. FIG. 2 shows a first, relatively compact configuration, wherein the dumbbell supporting portions of the supports 120a and 120b extend parallel to one another, and the dumbbells 90a and 90b are adjacent one another (with a distance K1 defined between their geometric centers). FIG. 1 shows a second configuration, wherein the dumbbell supporting portions of the supports 120a and 120b cooperate to define a V-shaped arrangement, and a person may stand directly in front of an edge of the tray 140 and between the dumbbells 90a and 90b (because a relatively greater distance K2 is now defined between their geometric centers). Generally speaking, the dumbbell supports 120a and 120b are configured (with an intermediate bend that defines an angled, V-shaped configuration when viewed from above) and arranged (at opposite sides of the intermediate frame member 110) so that the distance K1 is about six inches, and the distance K2 is about twenty inches. An even greater distance is defined between the rollers 128a and 128b on the leg portions of the dumbbell supports 120a and 120b in FIG. 1.
FIG. 5 shows a third configuration, wherein the dumbbell supports 120a and 120b have been rotated 180 degrees as compared to FIG. 2, leaving even more space for a person to stand therebetween and directly in front of an opposite edge of the tray 140 (because an even greater distance K3, or about twenty-four inches, is now defined between the geometric centers of the dumbbells 90a and 90b). FIG. 6 shows the stand without the tray 140 or the cradles 129a and 129b attached thereto, allowing the dumbbell supports 120a and 120b to be rotated to a relatively compact configuration relative to the intermediate frame member 110 (for shipping and/or long-term storage).
A second exercise system constructed according to the principles of the present invention is designated as 200 in FIGS. 7–10. The system 200 may similarly be described in terms of the same pair of known selectorized dumbbells 90a and 90b disposed on another novel dumbbell stand.
A functionally identical weight base or cradle 229a and 229b is provided for each dumbbell 90a and 90b to support the weight plates in proper alignment when not in use. The cradles 229a and 229b are mounted on respective first and second dumbbell supports 220a and 220b by bolts (not shown) or other suitable means. The bottom of each cradle 229a and 229b is preferably provided with a partially cylindrical channel that registers with a respective dumbbell support 220a or 220b. 
Each dumbbell support 220a and 220b may be alternatively described as a generally U-shaped member having a vertical leg portion that is supported by an underlying floor surface, an intermediate beam portion that extends horizontally and supports a respective dumbbell 90a or 90b, and another vertical leg portion that is rotatably connected to a respective intermediate frame member 210a or 210b (by suitable connecting means). Each first leg portion terminates in a lower distal end, to which a respective caster-type roller 228a and 228b is preferably rotatably mounted. A generally C-shaped loop 227a or 227b is rigidly mounted onto each first leg portion (by welding or other suitable means) to serve as a towel holder and/or a handle for maneuvering the stand across the floor.
The intermediate frame members 210a and 210b may be described as generally S-shaped members having respective intermediate portions that extend horizontally and are interconnected to one another by bolts 216 or other suitable means. Each frame member 210a and 210 has a respective downwardly extending leg, on which a respective caster-type roller 218a or 218b is rotatably mounted. Each frame member 210a and 210b also has a respective upwardly extending post or shaft, on which a respective dumbbell support 220a or 220b is rotatably mounted.
Snap buttons 212 are disposed inside the post portions of the frame members 210a and 210b, and they project through holes in respective frame members 210a and 210b and aligned holes 222 in respective dumbbell supports 220a and 220b. The holes are arranged to latch the stand in either of the configurations shown in FIGS. 7 and 8. In this regard, FIG. 8 shows a first, relatively compact configuration, wherein the dumbbell supports 220a and 220b extend parallel to one another, and the dumbbells 90a and 90b are adjacent one another (with a distance L1 defined between their handles or geometric centers). FIG. 7 shows a second configuration, wherein the dumbbell supports 220a and 220b cooperate to define a V-shaped arrangement, and a person may stand directly in front of an edge of the tray 240 and between the dumbbells 90a and 90b (because a relatively greater distance L2 is now defined between their handles or geometric centers). Generally speaking, the dumbbell supports 220a and 220b are configured and arranged so that the distance L1 is about six inches, and the distance L2 is about twenty inches (and the associated distance between the rollers 228a and 228b is even greater). FIG. 11 shows how the dumbbell supports 220a and 220b may be rotated to a relatively compact configuration relative to the intermediate frame members 110a and 110b (for shipping and/or long-term storage).
FIGS. 7–10 show the stand with a tray 240 mounted on the dumbbell supports 220a and 220b to provide upwardly opening compartments for storage of personal items. For example, the depicted tray 240 provides a cylindrical compartment 243 to support a beverage container; shallow triangular compartments 244a and 244b to store jewelry, keys, lip balm, or other suitably sized items; a relatively deeper compartment 245 to store a hand-held remote control device, a folded magazine, or other suitably sized items; a compartment 246 to store jewelry, keys, lip balm, or other suitably sized items; a compartment with a clip 247 to store paper items, jewelry, or other suitable sized items, and a slot 248 to store a spiral bound note pad with a pencil inserted through the spiral binder. On the depicted embodiment 200, the tray 240 is placed on top of the dumbbell supports 220a and 220b, and U-shaped collars (not shown) are disposed about the vertical portions of respective supports 220a and 220b and connected to respective inwardly facing portions of the tray 240 by screws or other suitable means.
A third exercise system constructed according to the principles of the present invention is designated as 300 in FIGS. 12–15. The system 300 may similarly be described in terms of the same pair of known selectorized dumbbells 90a and 90b disposed on yet another novel dumbbell stand.
A functionally identical weight base or cradle 329a and 329b is provided for each dumbbell 90a and 90b to support the weight plates in proper alignment when not in use. The cradles 329a and 329b are mounted on respective first and second dumbbell supports 320a and 320b by bolts (not shown) or other suitable means. The bottom of each cradle 329a and 329b is preferably provided with a partially cylindrical channel that registers with a respective dumbbell support 320a or 320b. 
Each dumbbell support 320a and 320b may alternatively be described as a generally J-shaped member having a vertical leg portion that is supported by an underlying floor surface, a horizontal beam portion that supports a respective dumbbell 90a or 90b, and a shorter vertical portion 324a or 324b that is rotatably connected to a respective side of an intermediate frame member 310 and/or tray 340 (by suitable connecting means). Each leg portion terminates in a lower distal end, to which a respective caster-type roller 328a and 328b is preferably rotatably mounted. Each shorter vertical portion 324a and 324b is inserted into a respective hole in the tray 340.
In addition to providing support for the dumbbell supports 320a and 320b, the tray 340 is preferably configured to provide both a means for latching the dumbbell supports 320a and 320b in desired positions (as further discussed in the next paragraph), and upwardly opening compartments for storage of personal items. For example, the depicted tray 340 provides a first cylindrical compartment 343 to support a beverage container; and a second cylindrical compartment 345 to receive jewelry, keys, lip balm, or other suitably sized items. On the depicted embodiment 300, the tray 340 slides onto an upper portion of an intermediate frame member 310 and may be secured in place by bolts (not shown) or other suitable means.
With regard to the latching means, the tray 340 includes upwardly extending nubs 341a and 341b and upwardly extending stops 342a and 342b on respective sides of the tray 340. In FIG. 12, each dumbbell support 320a and 320b is disposed between a respective nub 341a or 341b and a respective stop 342a or 342b. In FIG. 13, each dumbbell support 320a and 320b is disposed between a respective nub 341a or 341b and a respective portion of the intermediate frame member 310. On one embodiment, the nubs 341a and 341b may be formed as leaf springs that resiliently deflect downward to accommodate movement of the dumbbell supports 320a and 320b between these two configurations, and on another embodiment, they are rigid features that require the dumbbell supports 320a and 320b to be lifted slightly to accommodate reconfiguration.
The intermediate frame member 310 may be described as an inverted, generally U-shaped member having first and second downwardly extending legs, and an upwardly extending intermediate portion 314 that is also an inverted, generally U-shaped member. Plastic feet 313a and 313b are mounted on the lower distal ends of respective legs (although caster-type rollers could be used in the alternative). The intermediate portion 314 inserts through a central slot in the tray 340, and may serve as a towel holder and/or as a handle for maneuvering the stand across the floor. Extending from opposite ends of the intermediate portion 314, the symmetrical horizontal portions of the frame member 310 define shoulders that underlie the tray 340, and provide support for both the tray 340 and the dumbbell supports 320a and 320b. 
As suggested by FIGS. 12 and 13, the stand may be rearranged or transformed into multiple configurations. FIG. 13 shows a first, relatively compact configuration, wherein the dumbbell supports 320a and 320b extend parallel to one another, and the dumbbells 90a and 90b are adjacent one another (with a distance of about six inches defined between their geometric centers). FIG. 12 shows a second configuration, wherein the dumbbell supports 320a and 320b cooperate to define a V-shaped arrangement, and a person may stand directly in front of an edge of the tray 340 and between the dumbbells 90a and 90b (because a relatively greater distance of about twenty inches is now defined between their geometric centers). In addition, the stand may be readily broken down into pieces for shipping and/or long-term storage by removing the dumbbell supports 320a and 320b from the tray 340, and removing the tray 340 from the frame member 310.
The foregoing description and accompanying drawings are directed toward specific embodiments with the understanding that various features may be mixed, matched, altered, and/or eliminated without departing from the scope of the present invention. In construing the nature and scope of the present invention, no special significance should automatically be attributed to the fact that some features and/or advantages are discussed and/or shown in greater detail than others, or included on some embodiments but not others. For example, various accessory trays may be mounted on other types of dumbbell stands, and/or mounted in different ways on the foregoing embodiments. In this regard, a tray may be configured and arranged for mounting on one of the dumbbell supports rather than, or in addition to, a tray mounted on an intermediate frame member, and/or one or more such trays may be mounted on respective dumbbell supports that are not even associated with an intermediate frame member.
Among other things, multiple embodiments have been shown and described to help demonstrate that the present invention may be implemented in various ways. For example, the depicted dumbbell supports may be movable subject only to frictional resistance, gravitational resistance (to the extent that they must first be lifted before pivoting), and/or resilient resistance (provided by leaf springs on a tray). In addition or the alternative, the dumbbell supports may be locked against movement by snap buttons interconnected between the dumbbell supports and the intermediate frame member(s); spring detent pins inserted though aligned holes in the dumbbell supports and the intermediate frame member(s); and/or caster-type rollers of the type that may be selectively locked against rotation. Recognizing that many variations are contemplated, and that this disclosure will enable persons skilled in the art to realize such variations and/or derive additional embodiments of the present invention, the scope of the present invention should be limited only to the extent of the following claims.
