To all whom it may concern:

Be it known that I, LEO O. BERGMANN, a citizen 'of the United States, and resident of Coloma, Berrien County, Michigan, have invented a certain new and useful Improve ment in' Punching-Bag Supports, of which the following is a specification. I

This invention relates to punching bag supports for supporting a punching bag in a doorway, or in a similar opening, orany space between two uprights, whereby the bag maybe adjusted up and down and securely retained at the desired height; Generally stated, the object of the invention is to ,provide a. novel and desirable punching bag support of the foregoing general character, having means for utilizing the sides of the doorway or a similar structure as guides for the up and down adjust ment of the support, in such a way that tightening of the support in place will not tend to push the sides of the doorway away from each other, or to distort the doorway in any other manner, as will hereinafter more fully appear,

7 It is also an object to provide a novel constructlon and, arrangement whereby the bag reacts against a ring which can be readily taken off or rein'oi' 'ed, to permit use thereof by holding the ring in the haiids and swinging the bag first to one side and then to the other, or for other purposes, as will hereinafter more fully appear.

It is also an object to provide terminustails and features of construction and coinbinations tendingto increase thegeneral efficiency and the desirability of a punching bag support of this particular construction.

To these and other useful ends the invention consists in matters hereinafter -set forth and claimed and shown in the accompanying drawings in which "Figure 1 is a front elevation of a punching bag support embodying the principles of the invention, showing the punching bag support thereon, and showing the support clampedin place upon the sides of the doorway-that is to say, upon the two sides of the door frame.

Figure 2 is a sectionon line 22 in Figii heel-like support to the bottom of the cross bars which are clamped to the door frame.

As thus illustrated, the punching 1 may be of any suitable character, and is supported by a rope ,or other fieiribl'e connection 2, from the metal hub 3 secured by screws l tothe spokes '5 and the ring '6, the-ring and the spokes forming a wheel-like support for the bag, and the bag reacting against the under side of said ring: To provide resili'ence; the ring 6 is connected-to the spokes 5 p 7 each hand being gripped around the ring at such time. x

To support the punching bag in a dooi way, or on a similar structure, horizontal clan'ipi-ng bars 8 are provided, these bars having relatively thick end portions 9 at one end, and having relatively thin end portions 10 at the other end, witlr facings ii for all of said end portions, these facings preferably comprising sections of rubber to engage the door frame. The relatively thin portions 10 are desirable in order that either one of these ends may beinserted between the door frame 12 and the swinging door 13 at one side of the doorway. Thus the doorcan be at either side of the doorway, and still the clamping bars can be applied in position as shown. Transverse tie bolts 14 extend through the clamping bars adjacent the doorway, and are provided at their ends with thumb nuts 15 which, when tightened, will cause the clamping bars to tightly clamp the-two sidesof the door frame. These bolts when tightened, of course, tend to bring the middle portionsof the two bars toward each other, the bars being somewhat fie'Xibfle when made, forexample, of wood, or other similar material.' To' counteract the tendency of the bars to bend toward each other, a transverse metal bolt 1'6 is provided and inserted through the twb bars; and

thumb nuts 17. are applied to said bolt's to press against the inner sides of said bars,'so that the latter cannot be sprung toward each other at this point. ThebarsS extend straight across fremorie vertical member 12 to the other member 13, and the camping means 14 and 15 are between the two vertical members. Thus the bag 1 hangs in the plane of the vertical members 1 1 and 15, and the apparatus is well balanced. Vertical bolts 18 are inserted through the two bars at about the middle of the structure thus formed, and metal clamps 19, such as the one shown in Figure 3, are provided with notches 20 to receive these bolts. Th'umb nuts 21 are applied to the lower ends of said bolts 18, to draw the clamps 19 upward against the lower sides of the spokes 5 previously mentioned. 1 Thus the radial bars or spokes 5 are clamped tightly against the lower edges of the bars 8 in the manner shown. A slight loosening, however, of the thumb nuts 21, will permit removal of the clamping bars 19, so that the entire wheel-like support formed by the spokes 5 and the ring 6 can be detached from the overhead supporting bars 8, without removing the latter from the doorway. In use, the apparatus is placed in a doorway, as shown in Figure 1, with the nuts 15 just tight enough to moderately clamp the bars 8 to the door frame. If the height is not right for the user, the bars are pushed upward or downward until the desired height is obtained. tightened to prevent any displacement of the apparatus when thus clamped in position on the two sides of the door frame. The clamping of the apparatus in place does not tend to push the two sides of the doorway away from each other, and does not tend to distort the doorway in any manner, and will not mar or injure the woodwork of the door frame. The two sides of the door frame serve as guides, each side being interposed between two compressionjaws (formed by the opposing end portions of the bars 8 of the support) but the compression of the two sides of the frame does not tend to do any harm. Moreover, the support is thus firmly secured in place, without danger of displacement, no matter how violently the bag may be punched and caused to rapidly react against the under side of the ring 6 in the customary manner. 21, as previously explained, the bag and the bag ring can be removed intact for use in the manner described, without loosening or disturbing the bars 8 in their adjusted posi tion on the door frame. It will be seen that the two sides of the doorwayv are compressed, as explained, and that the compression is in a direction at right angles to the plane of the doorway.

It will be seen that the frame member 5 is removably clamped to the bottom of the support 8, and that the ring 6 is hung from the bottom of said. frame member 5, whereby when viewed from above, or from below, said member '5 in effect forms the spokes of a h el 1 w e l-like mb r Whisk aid Then the nuts are By loosening the nuts ring 6 is the rim or periphery. The supporting members 8 are movable up and down on the sides of the doorway, without any limitation of adjustment, so that the punching bag can be used by a small child or by a tall man. The springs 7 serve to resiliently support the ring on the supporting member 5, and this supporting member and the ring are removable with the bag, so that the ring and supporting member and bag are removable intact from the bottom of the overhead support 8 which is adjustable vertically on the two vertical members 12, in the manner explained. The members 8 form a connection from one member 12 to the other member 12, so that this overhead support is not destroyed or disturbed by the removal of the frame 5 and the ring 6 and the bag 1, as the frame 5 forms no part of the vertically adjustable support which reaches from one side of the doorway to the other. The overhead supporting structure formed by the bars 8 is adjustable up and down, practically without limitation, except for the limitation imposed by the height of the sidemembers 12, as the latter form the sole and only supporting means for said bars. As shown, a punching bag is supported on the frame member comprising the radial portions 5, but it is obvious that the vertically adjustable overhead supporting structure formed by the clamping bars 8 can be used to support an athletic or gymnasium device of any suitable, known or approved character.
