Definitions

  • the invention generally relates to heavy training bags and, more specifically, to a liquid-fillable heavy training bag.
  • Heavy training bags sometimes referred to as simply heavy bags or training bags, have been used for many years. These types of bags, also commonly called punching bags, are generally sturdy bags designed to be repeatedly punched or kicked for use for exercise or physical training. Such heavy training bags are typically used to improve one
  • Such bags can be, for example, 32"- 45" long, approximately 14" wide and typically weigh 70-100 pounds. Many of these bags are stuffed with a specially blended filler material to absorb punches or kicks without excessive lateral movements as it is intended that these bags provide resilient shock absorbency to somewhat stimulate the shock absorbing properties of an opponent. Depending on the intended feel of the bag, the outer cover may be stuffed with different filler materials. In some cases, dual bag shock absorption systems are provided by including a foam layer or lining in addition to the filler material.
  • a disadvantage of conventional heavy or training bags is that they are heavy when filled with filler material and are bulky. Most such bags are in their fully expanded conditions, that they assume during use, so that a purchaser can simply remove the bag from the box or other packaging, hang up the bag and start using it. However, while this is convenient for the end user, these bags are heavy and expensive to ship, display, store by retailers and all of these issues increase the cost of the item.
  • One approach that has been proposed to eliminate at least some of these problems is to provide a heavy or training bag that is initially in a collapsed form that can be expanded by the ultimate purchaser or user prior to use.
  • One common design is to provide a bag that has all of the common dimensions of conventional bags but has an inside liner or bladder that can be filled with water or other fluid.
  • the water or liquid is sufficiently heavy so that when the bag is filled up it has the weight and shock absorbent properties that simulate those of conventional fiber- filled bags.
  • These bags have the advantage that they can be shipped and stored in a collapsed form and can also be emptied of the water or fluid when the bag is not to be used for an extended period of time to facilitate storage of the bag.
  • liquid filled bags have been proposed, many suffer a number of disadvantages.
  • One disadvantage is that the punches or kicks applied to the bag provide substantial shock waves within the water or liquid and these, especially over time, can have the effect of weakening and ultimately breaking the liner or bladder.
  • Fig. 1 is a perspective view of a heavy training bag in accordance with the present invention, shown suspended from a support surface and ready for use.
  • Fig. 2 is a cross-sectional view of the heavy training bag shown in Fig. 1 taken along a longitudinal section line 2-2.
  • Fig. 3 is a cross-sectional view of the bag shown in Fig. 2, taken along a transverse section along line 3-3.
  • Fig. 4 is a elevational view of a section of the interior surface of the heavy training bag, as viewed along the region 4-4 in Fig. 3.
  • Fig. 5 is a perspective view of a section of the heavy training bag shown in Fig. 4. DESCRIPTION OF PREFERRED EMBODIMENT
  • a liquid-fillable heavy training bag in accordance with the present invention is generally designated by the reference numeral 10.
  • the bag 10 includes an outer tubular shell or cover 12 which has a bottom wall at a lower end 12a and a top wall at an upper end 12b.
  • the outer tubular cover 12 is a generally cylindrical flexible outer shell that may be made from any one of a number of materials typically used for conventional bags. This includes canvas, vinyl, leather or any other strong flexible sheet material that can withstand repeated punches or kicks to the outer surface of the bag.
  • the bag 10 may be made in virtually any size commonly used for conventional bags.
  • the cover defines a generally closed cylindrical inner surface 12c.
  • outer tubular cover or shell is shown as a right circular cylinder giving circular upper and lower walls, it is possible to provide the cover or shell 12 with different configurations, including square, triangular, etc. cross-sections.
  • a number of support straps 14, typically 3 or 4 are secured to the upper end 12b by means of any attachment means, such as stitching 16 although other devices maybe used to attach the straps such as rivets or other fasteners.
  • the support straps 14 may be formed as strips folder over to create an outer portion 14a and an inner portion 14b, both portions of which are secured to the outer tubular cover 12 such as by stitching. This creates a through opening 18 in each of the support straps 14 for accommodating a portion of a loop, link or ring 20. While a triangular link is shown in Fig. 1, it will be evident that any shaped link may be used and such links are preferably made from a rod the ends of which are welded to each other to form a closed link, ring or loop to prevent the link from opening after repeated stresses applied during use of the bag.
  • a ring 22 is secured to a support surface 24 in any conventional manner and chains 26 extending between each of the links 20 and ring 22 support the bag 10.
  • the bag is balanced when the support straps 14 are substantially uniformly spaced about the bag as shown. Any suitable means for securing the chains 26 to a support surface may be used.
  • the links of the chains 26 are also preferably welded so that they don't open as a result of significant stresses applied when the bag is punched or kicked.
  • a rim 28 is shown which is a curved or circular border or edge that extends about the periphery of the bag to create a recess 30 within which a top cover, wall or flap 32 is arranged that can be selectively and partially attached to the rim 28 or opened to provide access to the interior of the bag by means of a zipper 34.
  • a bottom wall 36 is provided that may be made of the same material as the outer tubular cover 12 and may be secured to the latter by any conventional means, such as stitching 38.
  • the bottom wall 36 is, therefore, permanently attached to the outer tubular cover 12, while the top cover or flap 32 is selectively attached to the outer tubular cover and may close the upper end in the region of the recess 30 to block access to the interior of the bag or to open the upper end 12b to provide such access.
  • a lower foam disc 40 Inserted into the outer tubular cover 12 is a lower foam disc 40 which has a diameter substantially corresponding to the internal diameter of the outer tubular cover 12. In assembling the bag, the lower foam disc 40 is initially inserted to the position shown in Fig. 2.
  • an outer foam layer 42 is inserted that can either be a closed annular layer or may be a rectangular sheet that is folded upon itself to bring the opposing edges into abutment against each other when the outer layer 42 is inserted within the outer tubular cover 12.
  • an inner foam layers formed of alternating inner foam layers 44 and vertical hollow tubes 46.
  • the inner foam layers 44 and vertical hollow tubes 46 are preferably secured to the interior surface of the outer foam layer 42 by means of any suitable bonding agent 47, such as adhesive, mechanical bonding or the like to facilitate assembly.
  • any suitable bonding agent 47 such as adhesive, mechanical bonding or the like to facilitate assembly.
  • the specific dimensions of the layers 44 and tubes 46 are not critical but the outer diameters of the tubes 46 should be approximately equal to the radial thickness of layers 44 are in the range of 3-5 times the diameters of the tubes 46.
  • the diameter of the liner 48 in its expanded position, substantially corresponds to the inner diameter of the inner foam layers 44 and vertical hollow tubes 46 so that once the liner is filled with water it abuts against and presses on the inner layers and tubes 44, 46, respectively, to urge the outer foam layer 42 and outer tubular cover 12 radially outwardly to maintain the bag 10 in its desired overall configuration or shape shown on Fig. 1.
  • the outer layers 42 and the foam discs 40, 56 together form an outer layer of an intermediate layer of compressible material
  • the inner foam layers 44 and tubes 46 form an inner layer of compressible material of the intermediate layer.
  • the liner or bladder 48 includes a bottom wall 48a, a top wall 48b and a cylindrical side wall 48c. At the top wall 48b the liner is preferably provided with a downwardly extending lip or flange 48d as shown, hi order to provide additional support and compensate for the relatively heavy weight of the liner, once filled with water or other liquid, and to prevent sagging or downward bulging of the bottom wall 36, there is preferably provided an additional support member or disc 50 which may also be a foam layer whose diameter essentially corresponds to the diameter of the radial dimensions of the liner 48 when filled with fluid or other liquid 52.
  • the top wall 48b of the liner is provided with suitable closure 54 that is shown to include a male member 54b in the form of externally threaded neck, secured to a suitable attachment extension 54b which can be sealed to the lip or flange 48d by any suitable means such as adhesive, bonding or any other type of attachment which renders the joint resistant to escape of water or other fluid within the liner.
  • a female member 54c in the form of an internally threaded cap may be used to close and seal the liner after water or fluid 52 has been added and the liner expanded as shown in Fig. 2.
  • an upper foam disc 56 is preferably placed between the top wall 48b and the top cover or flap 32 to render the bag firm and to protect the user from any sharp objects all about the entire peripheral surface of the bag.
  • an important feature of the invention is the provision of inner foam layers 44 which are distributed between the outer foam layer 42 and the liner 48.
  • the inner foam layers 44 include a series of vertically spaced expanded sections 58 each of which includes a raised portion 58a and recessed portion 58b to give the expanded sections 58 the appearance of a "dog bone".
  • the expanded sections 58 are vertically spaced from each other and connected by means of constricted sections 60 that link the expanded sections together and are simply in the forms of thin ribs. Clearances or gaps 62 are preferably provided between the expanded sections 58 and in the vertical hollow tubes 46 to facilitate assembly.
  • the bladder or liner 48 By allowing the bladder or liner 48 to at least partially expand into a plurality of cavities there is a reduced risk for rupturing the bladder or liner 48 or damaging the closure over an extended period of time.
  • the advantages of the inner foam layers 44, when used in conjunction with hollow tubes or other resilient longitudinally disposed members is that the liner is maintained in its desired shape while providing continued support with the added flexibility of allowing limited expansion of the liner as noted.

Abstract

L'invention concerne un sac d'entraînement lourd pouvant être rempli de liquide et comprenant une coque externe flexible cylindrique dotée de parois supérieure et inférieure pour former une surface interne cylindrique généralement fermée. Un support approprié est prévu pour suspendre la coque externe cylindrique à un élément de support supérieur, comme un plafond. Un revêtement flexible imperméable au liquide généralement cylindrique est prévu à l'intérieur de la coque externe pour recevoir et contenir un support liquide comme de l'eau. Le revêtement est configuré et dimensionné pour se conformer généralement à la forme de la surface interne de la coque externe lorsque le revêtement est complètement expansé, comme lorsqu'il est rempli d'eau. Une couche intermédiaire est prévue, composée de matériau compressible et disposée entre la coque externe et le revêtement et en contact avec ceux-ci lorsque le revêtement est rempli de liquide. La couche intermédiaire forme un coussin pour absorber les impacts externes de la coque externe et absorbe et atténue les ondes de choc transmises au support liquide à l'intérieur du revêtement pour protéger le revêtement et mieux simuler le toucher d'un sac lourd non rempli de liquide traditionnel.
