PUNCHING BAG Filed March 28, 1955 IN VEN TORS United States atent "cc PUNCHING BAG Myer M. Glasberg, Revere, and Clarence S. Luitwieler, Jr., Winchester, Mass., assignors to American Stay Company, Malden, Mass., a corporation of Massachusetts Application March 28, 1955, Serial No. 497,131

4 Claims. (Cl. 272-78) This invention relates to an adapter device for punching bags and the like.

One object of our invention is to provide an adapter device for mounting in the reduced or neck portion of a punching bag, or similar article, whereby the adapter de vice can be connected, to suspension means from above, or, in another position, to supporting means on the floor.

In the attachment commonly used to connect a punching bag with a suspension member or other support, there is considerable strain and stress on the neck thereof which often tears or otherwise damages it, hence another object is to provide such an adapter device that makes the neck part of the bag stronger, and which itself assumes most of the stress and strain that occurs here during use of the punching bag.

A further object is to provide such an adapter device that is easy to mount in a punching bag, and is simple and relatively inexpensive to manufacture.

The foregoing and other objects, which will appear as the nature of the invention is better understood, may be accomplished by a construction, combination and arrangement of parts such as is disclosed by the drawing. The nature of the invention is such as to render it susceptible to various changes and modifications, and, therefore, we are not to be limited to the construction disclosed by the drawing nor to the particular parts described in the specification, but are entitled to all such changes therefrom as fall within the scope of our claims.

In the drawing:

Fig. 1 is a side elevational view of our adapter device with a suspension member for connection to overhead suspension means.

Fig. 2 is a side elevational view similar to, but taken at an angle of 90 degrees from, Fig. 1.

Fig. 3 is a top plan view of our adapter device; but with the suspension member omitted.

Fig. 4 is a side elevational view of our device mounted in a punching bag and connected to overhead suspension means.

Fig. 5 is a side elevational view of our device mounted in a punching bag and connected to supporting means on a floor.

As illustrated, our device has a plug or mount 12, which may be made of rubber or a rubber composition, for instance. It is inserted in the reduced portion or neck of a punching bag P, or the like, as shown in said Fig. 4 and Fig. 5. It has a relatively long, neck portion 14 from which extends a relatively short, skirt portion 16 that flares outwardly to one end of said plug 12. At the end of said skirt portion 16 said plug has a concave or sunken portion, as at 18, which contacts a bladder B in said bag P. At the end of said neck portion 14 a hole 20 extends inwardly for a short distance, such as /4 inch for in stance, and an interiorly, screw-threaded sleeve 22 or other holding member is firmly set in said hole.

Extending from the outside end of said neck portion 14 are recesses 24 at opposite sides which serve as guide- Wayr; to receive opposite end portions of a looped, suspen- 2,815,952 Patented Dec. 10, 1957 sion member 26, shown as a flat strap having holes 28 in each said end portion adjacent the end extremities thereof.

There is a hole 30 extending laterally through said neck portion 14 between said recesses 24, and in which an interiorly screw-threaded sleeve 32 is firmly set, and which receive retainingscrews 34, later explained. There are holes 35 in opposite sides of the neck of the punching bag P which are in alinement with said hole 30 and screwthreaded sleeve 32 when said plug 10 is in a predetermined. position in said punching bag P. Of course, a bolt could serve as a retaining member and extend through said

holes

35, 28 and 30, held by the usual nut at one end.

In use, said plug 12 is inserted into the neck of a punching bag P, projecting slightly outside, the lacing L on the bag is tightened to thus retain the plug in place. If the punching bag P is to be suspended, said strap 26 is inserted through a ring 36 and the two end portions thereof are inserted in said recesses 24. Two screws 34 are inserted through said holes 35 in said punching bag neck and through the holes 28 in said suspension strap 26 and they then enter and screw-threadedly connect with said sleeve 32. Said ring 36 has the usual swivel member 38 connected thereto which latter member is attached to an overhead supporting board 40 commonly used for punching bags.

When use of a punching bag supported by a stand or base 44 on a floor 46, is desired, a flexible rod 42, shown in said Fig. 5, is connected to a said stand 44, and a threaded end is screw-threadedly connected with said sleeve 22 in said hole 20. Thus, without removing the plug 12 from the punching bag P, or making any change therein, the latter can be attached to a floor stand, or it can be connected to an overhead support by attaching said suspension strap 26 thereto, as explained.

Since the punching bag is laced tightly at the neck, the retaining screws 34 need not necessarily be inserted through said punching bag holes 35; but can be inserted directly through said suspension member holes 28 and said laterally extending hole 30 through the neck portion 14 of the plug 12, as illustrated in Fig. 2. The plug will be held firmly in place by the tight lacing. Also it is possible to connect with the flexible rod 42 shown in said Fig. 5, without removing said suspension member 26; by merely moving the latter to one side and making the screw-threaded connection between said sleeve 22 and said rod 42.

What we claim is:

1. In combination, a punching bag having a reduced portion and an adapter device extending into said reduced portion comprising a plug having a neck at one end and a skirt flaring outwardly from said neck, said neck having two exterior recessed portions opposite each other, an interiorly, screw-threaded member mounted in said neck, a suspension member having two end portions which extend into said recesses, and a screw-threaded pin member extending through said reduced portions, end portions, and screw-threadedly connecting with said interiorly, screw-threaded member.

2. In combination, a punching bag having a reduced portion and an adapter device extending into said reduced portion comprising a plug having a neck at one end and a skirt flaring outwardly from said neck, said neck having two exterior recessed portions opposite each other extending from the outside end thereof, a holding member extending laterally in said neck, a suspension member having two end portions which extend into said recesses, and a pin member extending through said reduced portions, end portions and connecting with said holding member.

3. In combination, a punching bag having a reduced portion and an adapter device extending into said reduced portion comprising a plug having two exterior recessed portions therein, a hole in said plug extending laterally therethrough between said two recessed portions, a suspension member having two end portions which extend into said recesses, and a retaining member extending through said punching bag reduced portion, said'end portions and hole to thereby hold said suspension member to said plug. 7

4. In combination, a punching bag having a reduced portion and an adapter device extending into said reduced portion comprising a plug having a neck at one end and 10 a skirt flaring outwardly from said .neck at the opposite end, said neck having two exterior recessed portions at opposite sides thereof and commencing at the outside end into said recesses, and two screw-threaded, pin members extending at opposite sides through said punching bag reduced portion, said end portions and screw-threadedly connecting with said interiorly, screw-threaded member.
