Abstract
A free-standing bag base suitable for supporting a training bag weighing up to about 275 lbs. The base of the bag is configured to enable the user to approach the bag's punching surface without impediment. Additionally, to improve access to the bag, the post is angled away from perpendicular.
Description
- The present application claims priority to U.S. Provisional Application No. 63/212,309 filed on Jun. 18, 2021.
- Boxers and martial artists often practice punching combinations and leg kicks on punching bags to safely train striking techniques. Free-standing bags, a common training tool, have the advantage of nonpermanent installation and may be moved when not in use.
FIG. 1 depicts a prior art free-standingweighted training bag 1. The prior art configuration utilizes aweighted base 3 to ensure it remains upright while a user punches or kicks paddedbag 5. These configurations also have apost 4 which supportsbag 5. To perform optimally, a freestanding bag base may weigh up to 275 lbs. when filled. Due to the design of thebase 3 andvertical post 4, the center of gravity (CG) is relatively high in current free-standing bags. In the prior art configurationvertical post 4 is located on thevertical axis 8 of the CG. - Current free-standing
weighted training bags 1 have several drawbacks. In particular, these bags have anundesirable constraint zone 7.Constraint zone 7 limits the approach tobag 5. Thus, a new design for free-standing bags which removes theconstraint zone 7 while also providing stability is desirable. - Disclosed is a weighted free-standing
training bag 10. The weighted free-standing training bag comprises a weightedbase 12 having at least twodetachable segments bottom surface 14, afront edge 13 and at least onecompartment 15 suitable for receiving a first mass having a mass between about 50 kg and about 100 kg. Additionally, the weighted base includes abase post 16 and abase stem 17 having a central axis. The base post is removably secured to said weighted base and projects upwardly from said weighted base at an angle between about 5° and about 10° from a vertical axis passing through a center ofgravity 20 located within said weighted base. Likewise, the base stem is positioned over the base post and the central axis defined by the base stem corresponds to the axis defined by the base post. Positioned on the base stem is atraining bag 18 having a centrally locatedslot 26, a frontupper bag edge 22 and a frontlower bag edge 24. In the assembled configuration of the weighted free-standing training bag, said base stem is positioned within said slot. The training bag provides a second mass between about 1 kg and about 5 kg. The total masses of the base, the post, the stem and the bag will generally range from about 50 kg to about 100 kg. Additionally, the total masses determine a location for the center of gravity of said weighted free-standing training bag. The center of gravity is located between about 7 inches and about 10 inches above the bottom surface of the weighted base. The front edge of the weighted base is located between a vertical plane defined by the front lower edge of the bag and the central axis of the base stem. The front lower edge of the bag is located between about 13 inches and about 19 inches from the vertical axis passing through the center of gravity. The front upper edge of the bag is located between about 15 inches and about 24 inches from the vertical axis passing through the center of gravity. -

An additional advantage provided by weighted free-standingtraining bag 10 is the segmented construction ofweighted base 12. The segmented construction ofweighted base 12 improves the ability to transport weighted free-standingtraining bag 10 to different locations. - With continued reference to
FIGS. 2-8 , weighted free-standingtraining bag 10 includes aweighted base 12. As depicted inFIGS. 4, 5 and 8 ,weighted base 12 has at least two fitted,detachable segments compartment 15 suitable for receiving a mass. Typically, the mass will be water, sand or metal pellets. In most instances,segments segments b defining compartment 15. Generally, a removable lid orcap 19 will be provided for ease of adding and removing weight.Base 12 also has arear edge 11 located onsegment 12 c. - In the embodiment of
FIG. 8 ,weighted base 12 has fourdetachable segments segment compartment 15 suitable for receiving a mass such as sand or water. Thus, eachsegment training bag 10. - Generally, the total mass within
weighted base 12 will be between about 50 kg and about 100 kg. More commonly, the total mass inweighted base 12 will be between about 72 kg and 90 kg. The total mass required inweighted base 12 will vary depending on the configuration of weighted free-standingtraining bag 10. If weighted free-standingtraining bag 10 is configured as a youth model, then weightedbase 12 will require less mass for stability. - In the embodiments of
FIGS. 8 and 9 ,lateral segments 12 b,d ofweighted base 12 may contain from 25 kg to about 35 kg of added mass. Typically,lateral segments 12 b,d will contain about 30 kg. In the embodiment ofFIG. 8 , front andback segments segments 12 a,c will contain about 45 kg. In one embodiment, as depicted inFIGS. 9 and 27A -E and 28A-B,front segment 12 a may be omitted to further reduce theconstraint zone 7. In these embodiments,segment 12 c may contain from about 40 kg to 50 kg of added mass. - The embodiment of
FIGS. 27A-E and 28A-B depict an alternative interlinking arrangement for joiningsegments 12 b, c and d. As best seen in the bottom view ofFIGS. 27D and 28B ,interlinking elements segments segment 12 c carries linkingelement 38 in the form of an outwardly projecting flange with one ormore receiving slots 42. Eachsegment element 39 in the form of at least one outwardly projecting tongue ortab 44 configured to slide into and frictionally engageslot 42 thereby securingsegments segment 12 c. In the embodiment of 27A-E and 28A-B, each segment will typically include a hollow chamber orcompartment 15 for receiving a mass. As depicted, each segment includes acap 19 for retaining the mass withincompartment 15. -
FIGS. 17A-F depict an embodiment ofweighted base 12, whereinsegments integral component chamber 15 andchamber 15 can be filled with any conveniently available mass such as water, metal pellets or sand by removal ofcap 19. - Likewise,
FIGS. 18A-F depict and embodiment whereinsegments integral component d forms chamber 15 andchamber 15 can be filled with any convenient mass such as metal pellets, water or sand by removal ofcap 19.Integral components 12 a,c and 12 b,d have a length E ranging between about 36 inches and about 38 inches. - Each segment of
weighted base 12 is secured to the adjacent segments through an interlocking mechanism or any other convenient device including but not limited to: snap click locking mechanisms, nuts and bolts, screws passing through one segment into an adjacent segment and other similar joining devices. For example, the embodiment ofFIG. 12 depicts the use of astrap 32 carried bybag 18.Strap 32 passes under and aroundsegments 12 thereby securingbag 18,segments 12 a-d,base post 16 and base stem 17 in the assembled configuration.FIG. 13 depicts a configuration with a shortened version ofbag 18. In this embodiment, a retaininghoop 34 is placed overbase stem 17.Hoop 34carries retaining strap 32 which passes under and aroundsegments 12 a-d ofweighted base 12. Thus, the various embodiments of weighted free-standingtraining bag 10 may be readily disassembled for relocation and/or transportation. -
Base post 16 ofweighted base 12 supports an upwardly projectingbase stem 17.Base post 16 may be integrally formed with one or more ofsegments weighted base 12 by any convenient device. For example, a threaded bolt, not shown, may extend from the bottom ofbase stem 17 and be received in a corresponding threaded hole within any one ofsegments base post 16 and base stem 17 may be integrally formed as a single component. -
Base post 16 is secured to weighted base at an angle other than vertical with respect to thebottom surface 14 ofweighted base 12. The central axis ofbase post 16 will generally define an angle between about 5° and about 10° with respect to avertical axis 36 passing through the center ofgravity 20 located withinweighted post 16. As depicted in the FIGS.,base post 16 is angled away frombase segment 12 c. In most instances, the angle defined by the central axis ofbase post 16 will be between about 6° and about 8°. Typically, the angle defined by the central axis ofbase post 16 will be about 7.5°. As depicted inFIG. 2 , the angle defined by the central axis ofbase post 16 with respect tovertical axis 36 passing through the center ofgravity 20 eliminates the constraint zone which limits the use of the prior art free-standing weight bag. -
Base post 16supports base stem 17. The central axis ofbase stem 17 is aligned with and is a continuation of the central axis defined bybase post 16. Base stem 17 may be secured by any conventional arrangement tobase post 16 including but not limited to friction fit, adhesives, threaded connections and/or threaded connectors. Further, as depicted inFIG. 2 , the angle defined by the central axis ofbase post 16 and base stem 17 is forward of center ofgravity 20. -
Training bag 18 has aslot 26 which receivesbase stem 17.Slot 26 may be of any configuration. Typically, the configuration ofslot 26 will correspond in shape to the exterior ofbase stem 17. As depicted inFIGS. 19A and 27A , base stem 17 may carry threads or grooves configured to engage with elements, i.e. corresponding threads, grooves or pins, within the interior ofslot 26 and assist in retainingbag 18 on base stem 174. Withtraining bag 18 installed onbase stem 17, the mass oftraining bag 18, the mass ofbase post 16, the mass of base stem 17 (about 3 kg to 8 kg for total mass ofbase post 16 and base stem 17) and the total mass ofweighted base 12 determines the location of the center of gravity (CG) 20. The location ofCG 20 provides stability to weighted free-standingtraining bag 10. As depicted inFIG. 2 , the location ofCG 20 is considerably lower than theCG 6 of prior art weighted bag 2. Thelower CG 20 of weighted free-standingtraining bag 10 contributes to the elimination of the constraint zone from the improved weighted free-standingtraining bag 10. The total mass of weighted free-standingtraining bag 10 will typically be between about 50 kg and 100 kg. More commonly, weighted free-standingtraining bag 10 will have a mass between about 72 kg and 90 kg. Most commonly,training bag 18 will have a mass of about 90 kg. Due to the described configuration ofweighted base 12 and the angle of the central axis passing throughbase post 16 andbase stem 17, weighted free-standingtraining bag 10 having a total mass of 90 kg will be as stable as a prior arttraining bag system 1 having a total mass of 125 kg. - The
lower CG 20 provides the ability to angle base stem as discussed above without loss of stability. As such,CG 20 is typically between about 7 inches and about 10 inches abovebottom surface 14. Distance A inFIG. 2 . More commonly,CG 20 is between about 7 inches and about 9 inches abovebottom surface 14. Generally,CG 20 is about 8 inches abovebottom surface 14. With thelower CG 20, the weighted free-standingtraining bag 10 can be configured such that frontlower edge 24 oftraining bag 18 is between about 13 inches and about 19 inches in front ofvertical axis 36 passing throughCG 20. Distance C inFIG. 3 . More commonly, frontlower edge 24 oftraining bag 18 is between about 14 inches and about 17 inches in front ofvertical axis 36 passing throughCG 20. Generally, frontlower edge 24 oftraining bag 18 is about 16 inches in front ofvertical axis 36 passing throughCG 20. Thus,front edge 13 ofweighted base 12 is located between frontlower edge 24 and the location where the axis defined bybase post 16 and base stem 17 intersectsbottom surface 14 ofweighted base 12. Thus, as depicted inFIG. 2 , frontupper edge 22 and frontlower edge 24 oftraining bag 18 are located forward offront edge 13 ofweighted base 12. - Likewise, front
upper edge 22 oftraining bag 18 is between about 15 inches and about 24 inches in front ofvertical axis 36 passing throughCG 20. Distance B inFIG. 3 . More commonly, frontupper edge 22 oftraining bag 18 is between about 17 inches and about 22 inches in front ofvertical axis 36 passing throughCG 20. Generally, frontupper edge 22 oftraining bag 18 is about 20 inches in front ofvertical axis 36 passing throughCG 20. Thus, the central axis ofbase post 16 and base stem 17 will normally pass in front ofCG 20. In other words, the central axis ofbase stem 17 does not pass throughCG 20. - Accordingly, the configuration of weighted free-standing
training bag 10 places frontupper bag edge 22 and frontlower bag edge 24 forward offront edge 13 ofweighted base 12. As depicted inFIGS. 2 and 3 , this configuration eliminates or at least greatly reduces the constraint zone. As such, an individual using improved weighted free-standingtraining bag 10 has a greater range of available motion when practicing punches and kicks. Further thelower CG 20 within weighted free-standingtraining bag 10 improves the stability of weighted free-standingtraining bag 10 during practice sessions, i.e. weighted free-standingtraining bag 10 is less likely to tip over. SeeFIGS. 10-13 . - Additionally, as depicted in
FIGS. 25 and 26 , improved weighted free-standingtraining bat 10 changes the position ofbase post 16 relative to theCG 20 as compared to the prior art free-standingtraining bag 1. Two forces counter impact energy applied by a strike to free standingweighted bag 6 and improved weighted free-standingtraining bag 10. These forces are static surface friction and resistance to rotation around the X axis of the CG. As depicted inFIG. 25 , in prior art free-standingtraining bag 1, the location ofpost 4 coincides with the location ofCG 6. Thus, the X and Y axes ofpost 4,bag 5 andCG 6 all coincide. As a result, energy resulting from an impact onbag 5 acts on equally on all components. In contrast, as depicted inFIG. 26 , improved weighted free-standingtraining bag 10 places the X axis ofbag 18 about 13 inches to about 19 inches in front of the X axis ofCG 20. The offset of the two X axis provided by the configuration of improved weighted free-standingtraining bag 10 increases resistance to tipping as energy applied tobag 18 is partially dissipated prior to acting onCG 20. - For devices such as depicted in
FIGS. 10-13 and 23-24 , the tipping point equals the moment experienced at the upper end of base stem 17 (post 4 in the prior art) and the point at which the center of gravity 20 (CG 6 in the prior art) passes over the corner of the object's base. Thus, lowering the position of the CG and moving the CG back, i.e. movingvertical axis 36 passing through theCG 20 increases the force required to tip weighted free-standingtraining bag 10 when compared to the force required to tip the prior art weighted free-standingtraining bag 1. The estimated tipping point angle for the prior art weighted free-standingtraining bag 1 corresponds to an angle of 42° between the bottom ofbase 3 and the floor. In contrast, the tipping point angle for improved weighted free-standingtraining bag 10 corresponds to an angle of 73° between the bottom ofweighted base 12 and the floor. As shown inFIGS. 23-24 , the tipping point angle of the bottom of the base to the floor corresponds to the point at which the CG of the base passesvertical axis 36 that is 90° relative to the corner of the base. Once theCG 6 has gone beyond 90° relative tovertical axis 36 passing through the back corner ofweighted base 3 in the prior art andweighted base 12, the device will tip over. Forprior art system 1 ofFIG. 23 , the tipping point angle is 42°. In contrast, improved weighted free-standingbag 10 has a tipping point of 73°. Typically, the tipping point of improved weighted free-standingbag 10 will range from about 60° to about 80°. Thus, improved weighted free-standingtraining bag 10 has a tipping point angle of the bottom of the base to the floor which is 40° to 45° greater than prior art weighted free-standingtraining bag 1. - Further, as a result of the greatly increased tipping point angle provided by improved weighted free-standing
training bag 10, the overall mass of weighted free-standingtraining bag 10 has been reduced when compared to the common 125 kg priorart training bag 1. Alternatively, one could opt to continue using a 125 kg weighted base thereby providing an exceptionally stable base when compared to the prior art. - Finally, when the user is striking the front of the weighted bag, the distance between acting forces and the tipping point has been increased from the prior art distance of 20″ to as much as 40″ for the improved weighted free-standing
training bag 10. As depicted inFIGS. 10-13 , in theprior art bag 1 the force of a blow acts at the center of the bag and the top of the base; however, a blow to the front of the bag of weighted free-standingtraining bag 10 acts upon weighted bottom 12 and the front ofweighted bottom segment 12 a. These improved characteristics are a result of the configuration of weighted free-standingtraining bag 10. Specifically, in the improved design, the distance from the frontupper edge 22 oftraining bag 18 to baserear edge 11 ofweighted base segment 12 c ranges between about 36″ to about 42″, more typically from about 38″ to about 40″. In contrast, the distances from the front ofbag 5 to the rear ofbase 3 in priorart training bag 1 is about 20″. - Other embodiments of the present invention will be apparent to one skilled in the art. As such, the foregoing description merely enables and describes the general uses and methods of the present invention. Accordingly, the following claims define the true scope of the present invention.
