Application November 18, 1954, Serial No. 469,578

1 Claim. (Cl. 272-78) The present invention relates to a striking bag out- .fit.

Although not specifically limited thereto, the present invention will be particularly described in regard to its application to a novel striking bag 'out-fit which may. be alternatively placed upon a floor or mounted upon the wall.

It is among the objects of the present invention to provide a solid, durable, readily adjusted and modified striking bag outfit which may be readily converted into different positions and combinations without tools :and without special skill.

Another object is to provide a simple, durable, readily modified platform and wall striking .sba'g combination which has alternative platform and wall support, and which may be readily placed upon wall brackets iorupon a floor without special operations either on the wallor floor upon each changing .or mounting of position.

A further object is to provide an inexpensive, readily itrmisported, assembled and installed four-way strikingbag outfit, which will permit exercise of substantially every :muscle in the body and which may be readily adjusted from swivel punching bag connection "to standing .up- .right position without tools and by a child without instruction or supervision.

Still further objects and advantages will appear in the more detailed description setforth below, :it being understood, however, that this more detailed description is given by way of illustration and explanation only and .not by way of limitation, since various changes nzh'erein may he made by .those skilled in the art without :departing from the scope and spirit of the present invention.

In accomplishing the above objects, it has :been found most satisfactory to form a base platform consisting-of U-shaped metal floor structure, one 'end of which will carry cross plates between thelegs of the RU :for a :platform to stand upon, :and the other-end of which will carry a cross member to support an alternative swivel and upright punching bag mounting arrangement.

To strengthen the platform and to enhance its construction a heavy metalrebound ring is mounted around and encircling the cross members which carry the punching :bag mountings.

-In the preferred :structure, there is supplied with the platform a plurality of U-shaped brackets having short side legs which are mounted permanently upon the wall of .the gymnasium, cellar, or outside play-ground.

These :three U-shaped'brackets :are designed tosupport the platform when 'it is'mounted in horizontal or vertical position on the wall to carry the punching bag in this position by the swivel connection.

These alternative mounting arrangements :are :desirably provided by means 'of bolt and nutconnections which fit through and engage registering --openings-in the side legs of the wall brackets.

The punching bag itself may be of the standard outer envelope with inner rubber bladder type, having a needle 2 valve nipple connection at the end of the bag outside the attachment.

The. lacedmounting end of the outer bag envelope may be provided with an inserted hollow flare and cone which will enable it to be mounted upon an upright resilient steel mounting for a standing punching position.

As an alternative, the rod may be disconnected from the end of the cone and a swivel eye connected. This swivel eye may in turn be connected to an S-shaped swivel on the cross bar of the platform.

The resilient vertical rod, which is used in upright punching'position is desirably of a telescoping sleeve construction with a locking set sc'rewto enable ready adjustment to the height of the-child or adult who -is using the same.

important features of the present invention reside in the platform which is a permanent non-articulated structure which does not have to be dismantled.

further important feature of the present invention :resides in the fact that the mounting for the platform when positioned horizontally or vertically upon a wall :is permanent and it is not necessary to make :repeated mounts or dismounting from the wall itself. This is accomplished by permanently mounted spaced U -vwallbrackets, which may the alternatively associated with side legs of the U-frame of ,the platform by readily removable sbolt .and nut connections.

A still further important feature of the present invention resides in the vertical, adjustable rod for supporting the bag "in an .upright position, and which may consist of a central rigid metal sleeve in which the resilient end rod extensions may .be telescoped. Gneof these end rod extensions may be adjustable so as to accommodate the -height:of the user.

With the foregoing and other objects in view the invention consists :of the novel construction, combination .and arrangements of parts as hereinafter more-specifically described, and illustrated in the accompanying drawings, wherein is shown an embodiment of :the invention, but it is to be understood that changes, variations and modifications can be resorted to which fall \m'thin the scope of the claim hereunto appended.

.In .the drawings wherein like reference characters denote corresponding parts throughout the several views:

Fig. 1 is a side perspective view showing the platform mounted horizontally .upon two wall brackets with bag suspended from the swivel connection.

Fig. 2 is a front elevational view showing an alternative wall mounting with the platform in vertical position and mounted .upon two brackets and the bag suspended from the swivel connection.

Fig. .3 .is a top perspective view showing the platform positioned :upon the .floor with the bag attached in swivel position.

Fig. 4 is aside perspective view showing the platform upon the floor with the bag mounted upon a resilient .adjustablerod and standing striking position.

Fig. .5 is a top plane view of the platform.

'Fig. 6 is a side sectional view :of the platform taken upon the line 6-4? of Fig. 5, showing the upright rod in position therein.

Fig. 7 is a fragmentary side perspective View showing the conical nlbber attachment element which is positioned inside and laced inside 'of the punching bag.

Referring to Figs. 1 to 6 there is shown a platform A having the cross bars or braces B for standing and the cross brace C carrying a swivel connection D and an upright connection E for'the punching bag 'F.

The platform A also carries the reinforcing ring G. 'The vertical 'rod'H will support the bag in the-position 3 of Fig. 4, while the S-swivel I will carry the bag in the position of Figs. 1, 2 and 3.

Associated with the device are the U-shaped brackets K-three in number-for supporting the platform A on the wall in the manner shown in Figs. 1 and 2.

Also provided are the side brackets L, which may be used for supporting the platform in the position of Fig. 1.

Referring specifically to Figs. 5 and 6, the platform A has a U-frame with the base 11 and side legs 12.

The side legs 12 are provided with the openings 13 adjacent to base 11, and 14 adjacent to ends of the legs at 15, have associations for mounting wall bracketsK.

The two cross members B, which serve as supports for the feet M of the user N, as indicated in Figs. 3 and 4, may be welded in position at their ends 16.

The ring G may be welded in position at the crossing points 17 and 18 to the side legs 12.

The cross platform C may be welded in position at 19 to the legs 12. This will give a rigidity and strength to the construction.

Although the dimensions, size and/ or materials may be changed, it has been found that a satisfactory platform may have an over-all length and width of 11" x 26", and that the U-frame 10 may be formed of strip steel 366 X n The rebound ring G is stationary and may be 18" in diameter and formed of solid steed rod.

On the cross bar element C, the swivel connection D is centrally located in respect to the stationary rebound ring G.

This swivel connection consists of a S-swivel J connected to the base eye 26. The eye 26 has a threaded shank 27 extending through the platform C and held in position by the lock nuts 28.

The connection E consists of a sleeve 29 which may be welded to the platform C and it has a locking screw 30.

The sleeve 29 is welded to the platform C to form a cup in which the lower end 31 of the rod H is inserted.

The rod H has two resilient end portions 32 and 33 the ends of which fit into the intermediate sleeve 34.

The end 35 of the rod 32 may be welded permanently into position to the lower end of the sleeve H; or the rod 32 may be notched and the sleeve H is slid over the notched part of the rod 32 and the metal of rod H is forced under pressure into the notch of rod 32, making a permanent attachment.

The rod 33 and its lower end 37 may have an adjustable telescoping connection in respect to the sleeve 34, and it may be held in any desired adjusted position by the lock screw or thumb screw 38.

The upper end 39 of the rod H may fit into an opening or hole in the rubber solid cylinder 40 which projects downwardly from the mounting cone 41. The mounting cone 41 fits into the lower portion 42 of the punching bag F. (See Fig. 7.)

The conical member 40 is laced in position inside the bag F as indicated at 41a in Fig. 7.

The upper end 39 of the rod is firmly held in position by the clamp 43 which has the clamping screw 44.

When the bag F is to be connected to the S-swivel J, the clamp 43 is loosened and the end 39 of the rod H is removed.

The shank of the swivel eye 55 is then inserted and clamped into position by the clamp 43.

Then the s-swivel hook I is engaged in the metal eye 55 so that the bag may be suspended or supported as shown in positions in Figs. 1, 2 and 3.

In connection with the wall mounted arrangement, as shown in Figs. 1 and 2, the three brackets K have the base members 56, which are apparently mounted on the wall by means of the screws, bolts, or other connections 57.

The ends of the base 56 are provided with the short legs 58, which have openings to correspond to the openings 13 and 14 of the platform A.

To support the platform A in the position shown in Fig. 1, two oblique braces L we provided, the top end 58 of which have openings which receive the screws or bolts 59.

The lower ends 60 of the braces L have openings which are connected by the screw or bolts 61 to the openings 14.

At the same time the end of the U-frame 19, adjacent to the base 11 will be inserted between the legs 62 of the bracket K and held in position by means of the bolts 63. In this manner the platform is suspended horizontally with the bag F, hanging from the swivel connection I, as shown in Fig. 1.

In the alternative arrangement of Fig. 2, the base portion 11 of the platform A is also inserted between the legs 62 of the middle bracket K and held in position by means of the nuts 63.

The ends of the legs 12 are positioned between the legs 64 of the lowermost bracket K and held in position by the nut 65.

In this position the oblique braces L may be left in position on the nuts 59 and permitted to hang loosely provided by vertical positioned platform A. Here also the bag F is suspended by the swivel connection I from the eye or ring 26.

In the position of Fig. 3 the only change from that of Fig. 4 is that the bag is connected to the swivel I and the vertical rod H is removed.

The changing and mounting in the arrangement shown in Figs. 1, 2, 3 and 4 is relatively simple and may be accomplished by a child without special tools or guidance.

The shank of the alternative eye 55 and the end 39 of the rod 33 may be exchanged by loosening the thumb screw 44, and removing one and inserting the other, as shown in Figs. 1, 4 and 6.

The eye 55 may be readily connected to or dismounted from the S-swivel J.

The three U-shaped wall braces K may be positioned upon the wall and left there without repeated dismounting and assembling.

The oblique braces L may be left in position as shown in Fig. 2 when not in use, and when in use, they may be readily connected as shown in Fig. 1.

The solid rebound ring G not only gives rigidity and strength, but also gives a firm rebound. The platform A is sufiiciently rigid to support children or adults, and at the same time it is lightweight so that it may be readily carried about. At no time is it necessary to dismantle the platform and it can be stand considerable abuse as contrasted to articulated plaforms.

The end rods 32 and 33 of the upright rod H give suflicient resiliency at the end and are desirably made of high carbon steel resilient material.

The intermediate sleeve 36 will give additional rigidity which is found to be best in a long resilient support such as indicated at H.

The transit rods 32 and 33 may be of A" diameter. As shown there are two wall positions indicated in Figs. 1 and 2, and two floor positions as indicated in Figs. 3 and 4.

The arrangement as shown is a particularly satisfactory four-way punching bag for children and adults.

The essential novel feature of the present application resides in the rigid base or platform structure A which takes the shape of the U and is formed of a single metal bar bent to form the base 10 and side legs 12, with the side legs 12 constituting parallel, upright side members (see Figs. 3 and 4).

The base A with its members 10 and 12 constitute an upright vertical structure as shown in Figs. 3 and 4, which is superimposed on the rigid rebound ring G welded to the side legs 12 in four positions at the end and at intermediate points along the legs 12 (see Fig. 2).

It will be noted that both the base 10 and the legs 12 are upright and vertical in the suspended position of Fig. l as well as the floor position of Figs. 3 and 4 with the ring G being closest to the user or closest to the back and in a lower position in Fig. 1 and in an upper position in Figs. 3 and 4. The base 10 constitutes a base upright, vertical, integral, transverse member and the legs 12 constitute parallel, upright, vertical side members.

The plate members B on the outside of the ring G and C on the inside of the ring G are also welded to the side legs 12 and enhance the rigidity of the structure, in addition to respectively forming a support for a person standing on the base and a support for the upright or depending punching bag F.

It will be noted that the ring G is welded adjacent an end of the platform and at four places on opposite sides of the ring.

As many changes could be made in the above striking bag outfit and many widely different embodiments of this invention could be made without departing from the scope of the claim, it is intended that all matter contained in the above description shall be interpreted as illustrative and not in a limiting sense.

Having now particularly described and ascertained the nature of the invention, and in What manner the same is to be performed, what is claimed is:

A base structure for a punching bag for use in the suspension of the bag from an elevated position or to provide a horizontal stand from which the punching bag may be uprightly mounted by a vetrical resilient adjusta'ble length rod, said base structure comprising an elongated U-shaped member of strap form metal and including a pair of spaced parallel legs and a bight portion unitary with the corresponding ends of the legs, and wherein said legs and the bight portion are of greater vertical dimensions than the thickness thereof, a rigid circular open rebound ring of greater diameter than the width of said U-shaped member, said ring being superposed on said legs in symmetrical relation thereto with equal arcs thereof overhanging the opposed legs, said ring being rigidly connected to each leg adjacent the free end thereof and being further rigidly connected to each leg at a point intermediate the free end thereof and said bight portion, a rectangular plate provided with punching bag supporting means disposed within said ring transversely of said legs with its opposite ends rigidly connected thereto, and a pair of rectangular plates disposed transversely of said legs adjacent said bight portion and being rigidly connected to the legs.
