BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention generally relates to exercise stands and more particularly to a heavy-bag and adjustable-position speed-bag workout stand.

2. Description of the Prior Art

Numerous prior art patents illustrate a multi-stand exercise center. These typically include a heavy bag and a speed bag. While some of the prior art constructions are more elaborate and probably more costly, U.S. Pat. No. 5,725,458 to Newman et al. illustrates a three-bag workout apparatus in which a central pole is mounted on a stand or base secured to the floor or mounting surface by means of screws. A speed bag is mounted on the pole in one plane, while a heavy bag is mounted on a slightly inclined extension pole in a plane laterally offset 90 degrees from the plane in which the speed bag is mounted. An additional punching bag is also provided that is secured between a bar and bolt secured to the base. The patentee states that the equipment is intended to be used in any “home, garage, backyard, or buildings with a concrete floor.” Thus, the base is intended to be secured to a cement or outdoor concrete patio area, although it is also contemplated that it can be moved without creating much damage to the stand. Thus, while “transplantable” from one area to another, the apparatus is intended to be bolted to the surface at any given location because with the construction used, it appears, the center of gravity, with the heavy bag mounted, is such that the entire stand would topple except for the bolts that secure the base to the concrete surface.

U.S. Pat. No. 5,863,278 to Chen discloses a support frame includes an upright rod on which a sandbag is mounted by means of a suspension rod, while the speed bag is mounted on the reverse side, as shown. Because the frame itself is relatively lightweight, three upright bars are provided, as shown, to allow suitable weights to be secured to the base frame members to assure the stability of the unit during use.

U.S. Pat. No. 6,220,992 to Shafik illustrates another example of a prior art boxing exercise apparatus formed of a frame that is adjustable in a number of different ways to support different types of punching bags, including a heavy bag and a speed bag, as shown. However, this patent does not disclose a heavy base to stabilize the unit, nor does it appear to be secured to the floor or surface on which it is positioned. However, it is disclosed that the frame is secured to uprights, a conventional treadmill, not shown in the figures.

Design Pat. D362,477 to Bluestein shows a combined exercise step and punching bag stand, in which the base appears to be in the form of a molded hollow structure that could be filled with water or sand.

Design Pat. D335,513 to Gaetano discloses a stand similar to the one shown in the Chen '278 patent, although it does not indicate any means for weighing the frame down. Instead, it appears that the frame itself is stabilized on the floor against toppling or sliding by means of a platform attached to the base of the frame on which the user stands. Presumably, the weight of the user creates sufficient friction on the plate adequate to prevent movements of the frame itself.

Other patents show multi-stand boxing centers utilizing some or all of the bags that can be used with the present invention. However, these patents do not appear to discuss the option in which there is an indoor/outdoor mobile stand that includes a heavy bag permanently supported on the frame, while a plurality of other bags can interchangeably be used one at a time.

Thus, numerous stands have been proposed, some of which allow for the vertical height adjustment of the speed bad. However, these stands primarily accommodate the height of the bag to the height of the individual using it. Such an adjustment capability is, of course, extremely useful, but it does not allow for lateral adjustment or the positioning of the speed bag within a generally horizontal plane relative to a stationary base. This may be a disadvantage if the stand must be placed in a predetermined position in a room, such as in its corner, and both the heavy bag and the speed bag must be positioned so that they can be conveniently and individually used notwithstanding their close proximity to the walls.

SUMMARY OF THE INVENTION

The present invention relates to a simple and inexpensive construction of an exercise heavy-bag and speed-bag stand or stand that allows the speed bag to be adjusted to a one of plurality of positions both to accommodate the height of the user as well as to accommodate the site where the stand is used in a room. Thus, in addition to height adjustability, the speed-bag platform may be moved to one of a plurality of different positions within a generally horizontal plane, so that it can, for example, be positioned diametrically opposite to the heavy bag or to one of a different number of positions angularly displaced from such position to various degrees to one lateral side or the other of such position to accommodate the geometry or the space in which the stand is placed or positioned. In this way, both bags can be desirably placed in positions where either one or both of the bags can be used independently of the other, while minimizing the amount of space used for the stand and enabling practice with either one of the bags without inconvenience or hindrance by the other bag or the physical constraints within the space such as walls or other pieces of exercise equipment.

The stand is of a simple construction that may be disassembled for easy shipment and quickly and rapidly assembled with minimal effort or tools. Once assembled, the stand is sturdy, steady and safe to use.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring now to the Figures, in which similar or identical parts are identified by the same reference numerals throughout, and first referring to FIG. 1, an adjustable position heavy-bag/speed-bag stand in accordance with the present invention is generally identified by the reference numeral 10.

The stand 10, in the form of a boxing, kicking or marshal arts center, includes a frame 12 that includes a base 14. The specific configuration of the base is not critical as long as it provides adequate stability and can be easily assembled from a fully collapsed disassembled condition that takes up a minimal amount of storage space. However, in the embodiment illustrated, the base 14 is formed of two S-shaped bent legs 16 that are generally mirror images of each other when assembled as shown. Each bent leg 16 has one remote free end 16a, as viewed in FIG. 1, and a proximate, generally parallel other free end 16b. Intermediate portions 16c extend between the end portions 16a and 16b.

The free ends 16a are generally juxtaposed proximate to each other in generally parallel relationship, and positioned on opposite sides of an upright 22 to which the free ends 16a are securely attached by any suitably means, such as nuts and bolts. A leg brace 18 extends between the intermediate portions 16c and may be attached thereto in any conventional manner to maintain the separation or spacing between the free ends 16b. It will be appreciated that the further the free ends 16b are spaced from each other, the wider the base and the greater the stability in the lateral directions. Similarly, a generally elongate stabilizer straight base leg 20 extends in a direction generally parallel to that of the leg brace 18 and has a length generally corresponding to the spacing between the free end portions 16b, to provide comparable stability at both the front and the rear of the base.

Referring to FIG. 2, the elements or components of the frame 12 are shown. Advantageously, the upright 22 is formed of two separate vertical upright portions 22b, 22c, split at 22d, as best shown in FIG. 8. The two vertical upright portions 22b, 22c can be joined by a connector C that has a cross-sectional configuration generally corresponding to that of the two upright portions to be joined, square tubes in the embodiment illustrated, and received within the tubes to bridge the split 22d. Appropriate fasteners, such as nuts and bolts or rivets R, can be used to secure the uprights to the C, as to be described in connection with FIGS. 7-11.

The L-shaped bottom or lower half of the upright 22 includes a horizontal portion 22a that is received and secured between the two free ends 16a by drawing the latter together in pressure relationship against the portion 22a. The transverse elongate stabilizer straight base leg 20 can be secured to the free ends 16a and horizontal portion 22a in any suitable and conventional manner.

To stabilize the upright 22 against movements in both the forward and rearward directions, as well as laterally, there are preferably provided two angular or side braces 23, the lower ends of which are secured to the bent legs 16 in the regions where the intermediate portions 16c merge with the proximate free ends 16b, as shown. The specific locations where the angular or side braces 23 join the base bent legs 16 is not critical as long as they provide adequate stability. The upper ends of the angular or side braces 23 are connected to the vertical upright portion 22c, as shown, preferably above the split 22d. However, the specific location where the upper ends of the braces 23 are joined to the upright 22 is not critical, although it will be evident that the higher the connection point, the greater the stability that is provided.

Referring to FIGS. 2 and 3, the upper horizontal portion 22e of the L-shaped top half of the upright 22 is generally parallel to the bottom horizontal portion 22a of the upright portion 22b. An eyelet bolt 24 is provided at the free end of the horizontal portion 22e from which a heavy bag B1 may be suspended. Referring to FIG. 1, the heavy bag B1 can be secured from the upper horizontal portion 22e in a conventional manner by attaching one end of the chains 26 to the eyelet bolt 24 by means of S-links 30, which are, in turn, secured to conventional fabric straps or loops 32 attached to the upper end of the heavy bag by means of triangular metallic links 34. At the lower end of the heavy bag B1, there may be provided an elastic band 36 having one end secured to an eyelet 37 by means of an S-link 38, while the lower end of the band can similarly be attached to a round loop or eyelet 40 by means of a S-link 42. The elastic band 36 is conventionally used to decrease the amount of sway in lateral, rearward or forward directions of the heavy bag when it is impacted.

With the illustrated design, the heavy bag B1 remains fixed in place along the vertical direction, so that the elastic band 36 remains taut or straight as shown. The uprights and the base are so configured and dimensioned so that the center of gravity of the heavy bag B1 generally passes through a central region of the footprint defined by the base 14. This provides substantially equal or comparable stability regardless of the direction of impact on the heavy bag B1.

An important feature of the invention is the provision of a speed bag B2 and the manner in which it is mounted on the stand 10 so that it is adjustable to accommodate both the height of the user as well as the geometry or configuration of the room in which the stand is used. Towards that end, there is provided a speed-bag support arm 44, which extends generally horizontally from the upper vertical upright portion 22c, as best shown in FIGS. 2 and 3.

Referring to FIGS. 3 and 4, the support arm 44 is attached to the upper surface of a generally circular speed-bag platform 46. In accordance with one feature of the present invention, the platform 46 is formed of two separate semicircular panels 46a, 46b, attached to each other by means of a piano hinge 46c, as best shown in FIGS. 5 and 6. By using this construction, the platform 46 can be folded and reduced in size for purposes of shipping and storage. However, the platform 46 can also be made out of a unitary rigid board that does not fold about a hinge as described. Where the size of the platform is not a problem insofar as shipping or storage is concerned, making the board rigid may have the advantage that the resulting support for the speed-bag is sturdier and provides improved performance and reliability. As shown in FIG. 1, the platform 46 is provided with a conventional ball pivot or swivel 48 of the type used to conventionally support a speed bag B2.

Referring to FIGS. 3 and 4, a quadrant assembly 52 is provided that can be suitably connected to the upper vertical upright portion 22c at one of a plurality of vertical positions. For this purpose, a plurality of transverse holes 64 is provided for allowing lateral flanges 54b of the quadrant assembly 52 to be connected to or mounted at different vertical heights by means of transverse fasteners 54a. While any fasteners can be used, nuts and bolts are preferably used so that they can be removed and reinserted at different heights or levels to provide the desired height for any given user.

A feature of the invention, referring to FIG. 4, is that the quadrant assembly 52 is also provided with a pair of vertically spaced plates 52a, 52b. In the embodiment shown, these plates are in the form of semicircular plates that are vertically aligned with each other and may be integrally formed with a transverse plate 52c to form a generally U-shaped receiving space 52e dimensioned to receive the proximate end of the support arm 44 with clearance. The plates 52a, 52b are provided with vertically aligned holes substantially proximate to the geometric center of the circular quadrant through which a pivot pin 56 is inserted that extends through the corresponding holes in the support arm 44. The support arm can, therefore, pivot about the pivot pin 56, while freely rotating about the pivot pin, limited only by the transverse plate 52c that serves as a stop. In order to secure the support arm 44 against rotation, there are preferably provided a plurality of sets of vertically aligned holes 52d, proximate to the circular peripheries of the plates 52a, 52b. In the embodiment illustrated in FIG. 4, five sets of such holes are provided. One set of holes are essentially aligned at the center of the circular arc within a plane that essentially extends through the upper horizontal portion 22e of the upright 22. Two of the sets of holes are arranged at substantially diametrically opposite ends of the position of the pivot pin 56 within a plane substantially parallel to the transverse plate 52c, while the remaining two pairs of holes are located approximately 45° between the two aforementioned sets of holes. It will be clear that the support arm 44 can be fixed in position at any one of five different angular positions relative to the upright 22 and the base 14 by simply moving the support arm 44 to one of the aforementioned desired positions and locking its position in place by means of a fixing pin 58. While five sets of holes have been illustrated, approximately 45° apart from each other along the arc defined by the semicircular plates 52a, 52b, it will be clear that any number of such sets of holes may be provided. These may be uniformly or equally spaced angularly spaced from each other, although they need not be so spaced. In this manner, the support arm 44 and speed-bag platform 46 may be moved 90° to the right of the rearmost position, 90° to the left of that position or any one of the discrete positions inbetween. In FIG. 1 the speed bag B2 is shown in the 90° to the right position to clear the walls at the corner of the room.

The quadrant assembly 52 may be secured to the upright portion 22c in any suitable or conventional manner. In the embodiment illustrated in FIGS. 4 and 5, the transverse plate 52c is shown connected to a bracket 54 having lateral flanges or walls 54a, 54b spaced from each other a distance to correspond to the width of the square or rectangular tube used for the vertical upright portion 22c. The two lateral flanges or walls 54a, 54b are connected to each other by means of a transverse flange 54c. These flanges define a receiving area 54d dimensioned to receive the upright portion 22c, as shown in FIG. 3. As indicated, any suitable fasteners 59 may be used to secure the quadrant assembly 52 at any desired height.

In accordance with the broader aspect of the invention, the speed-bag platform support arm 44 is angularly movable from side to side between the different angular positions while moving in a generally horizontal plane about the upright 22. In a presently preferred embodiment, however, the quadrant assembly is also vertically adjustable, as suggested in FIG. 3. In FIG. 3, the holes 64 are spaced 3 in. apart from each other so that the speed-bag platform may be positioned in one of five different vertical positions. Also, because five sets of vertically aligned hole 52d are provided, and the support arm 44 may be positioned in any one of five different angular positions, it will be clear that there are a total of 25 different adjustable combinations of positions for the support arm 44 and, therefore, the speed bag B2 itself. Of course, by changing the number of horizontal positions and/or the number of vertically aligned holes 52d, different numbers of total combinations can be obtained, the total number merely being the product of the number of vertical positions and the number of horizontal angular positions.

Referring to FIG. 4A, an alternate construction of the vertically spaced plates is shown. The modified plate, with two being provided as described, is identified by the reference numeral 52f. Instead of having a plurality of discreet holes 52d as discussed in connection with FIGS. 3 and 4 a continuous slot 52g is provided that extends proximate to the edge or periphery of the plate 52f. The associated plate (not shown) is similarly configured and vertically spaced to form the modified quadrant assembly 52. By providing a continuous slot the user is no longer limited to a finite number of horizontal positions but can position the bad in any one of an infinite number of positions between the ends 52h, 52i of the slot 52g. As shown in FIG. 4A, the slot 52g extends from one side of the diameter 80 of the plate 52f, which passes through the geometrical center 82 of the plate, to the diametrically opposite side of the diameter. This allows for 180° adjustment, as represented, for example, by the position 84. It should be evident that the arcuate length of the slot 52g is not critical and may be made shorter or longer than the slot shown to provide less or more positions of adjustability.

To enhance the stability of the speed-bag platform 46, and to prevent excessive stresses on such platform during use, there are advantageously provided at least one or two transverse bars 60 that are rigidly secured to the support arm 44, the speed-bag platform 46 being, in turn, secured to the transverse bars 60 themselves and not directly to the support arm 44.

Advantageously, weight pegs or posts 70 are provided that extend vertically upwardly from the free ends of both the proximate end portions 16b as well as the free ends of the straight base leg 20, as shown. The pegs or posts 70 can be used to secure weights (not shown) to provide additional stability to the base and to the stand during use. Additional stability can be provided by providing end caps 72, that can be slipped over the free ends 16a, 16b as well the free ends of the straight leg base 20, that are formed of rubber or the like, which will enhance the friction with the support surface. This minimizes movements of the stand on the smooth surface.

Referring to FIGS. 7-11, the assembly of the adjustable position heavy-bag/speed-bag will now be described. In FIG. 7 the two bent legs 16 are placed on the floor with the leg brace 18 between them, as shown. The leg brace may be secured to the bent legs in any conventional or suitable manner, such as placing the leg brace over square lugs (not shown) in the bent legs and fastening same with suitable nuts and bolts. The bottom half or horizontal portion 22a of the upright portion 22b is placed between the bent leg portions 16a.

The stabilizer or straight base leg 20 is placed across the free ends 16a and is secured to the three portions 16a, 20a by any suitable or conventional means, such as bolts and nuts.

The connector C (FIG. 8) is slid into the upright portion 22b, making sure that the holes in these members are secured with suitable nuts and bolts. The top half of the upright portion 22c is slid onto the connector C, again making sure that the holes are aligned, and that the heavy-bag arm or horizontal portion 22e is directed or pointed toward the front of the stand, as viewed in FIG. 1, pointing toward the leg brace 18. These are, again, suitably secured by means of nuts and bolts. Five plastic or rubber end caps 72 are now placed on the free ends 16b and on the straight base leg 20. One plastic end cap 74 is also advantageously used to cover the free end of the upper horizontal portion 22e to cover or conceal any sharp edges.

Referring to FIG. 9, the side braces 23 are connected to the vertical upright portion 22c, as shown, using suitable nuts and bolts, and the bottom ends of the side braces likewise are secured to the bent legs, as suggested, with appropriate fasteners. These fasteners can now be tightened to rigidify the structure, as shown in FIG. 9.

The heavy-bag holding eyebolt 24 is now extended upwardly through the heavy-bag upper horizontal portion or arm 22e and secured with a nut at the upper end. The speed-bag swivel or ball pivot 48 can now be attached to the center of the speed-bag platform 44, using wood screws. The speed-bag arm assembly, including the support arm 44 itself and the transverse bars 60, is now attached to the speed-bag platform 46 by means of suitable bolts and nuts.

The quadrant assembly 52 can now be attached to the vertical upright 22c using any one of the height adjustment holes 64 provided and one suitable bolt and nut.

Referring to FIG. 11, the speed-bag platform 46 and arm assembly can be secured to the quadrant assembly, between the upper and lower plates 52a, 52b. The fixing pin 58 can be removed and the support arm 44 moved to the desired angular position so that the holes in the support arm 44 are aligned with one set of vertical aligned holes 52d, so that the fixing pin 58 can be inserted through all of the holes in order to fix the angular position of the support arm.

Four weight pegs or posts 70 can now be inserted into the free ends of the base legs, as shown, which can be used to support weights for additional stability. The weight pegs can be secured to the bent legs 16 and to the straight stabilizer base leg 20 by means of suitable fasteners. In FIG. 11, the pegs or posts 70 are shown to be received within vertically aligned threaded or unthreaded holes within the free ends of the base tubes, as shown. In FIG. 12, an alternate embodiment is illustrated, in which the pegs or posts are secured to inverted U-shaped brackets 76 that are dimensioned to be placed over the free ends of the leg tubes or legs. The brackets may be secured to the tubes in any conventional way, including press fit, suitable nuts and bolts, machine screws, or the like.

It will be appreciated that by using the disclosed design, the free ends 16b are spaced sufficiently from each other to provide greater freedom to the user when working out.

Depending on the geometry of the space where the stand is to be located, and depending on the position of the stand within that space, the stand in accordance with the present invention provides maximum versatility and flexibility of use for maximum ease of use and comfort to the user, regardless of where the two bags, the heavy bag and the speed bag, are to be situated or located.

While this invention has been described in detail with particular reference to preferred embodiments thereof, it will be understood that variations and modifications will be effected within the spirit and scope of the invention as described herein.
