Punching bag and support
First Claim

1. A punching bag assembly comprising:
- a first bag, inflatable and having a wall of a first elastic material and an inflation orifice;
a second bag having a wall of a second elastic material and an opening in the wall, said first and second materials having substantially similar material properties, the first bag being contained within the second bag with the inflation orifice in register with the opening and inflated so that it exerts pressure outwards and distends the second bag, the elasticity of the materials helping to establish a tension in the walls of both bags so that said walls substantially unite to define a single resilient envelope; and
suspension means having a collar including an orifice and disposed in the opening of the second bag so as to be captured by the bags upon inflation of the first bag and retained between said walls by the tension established in the respective walls so that the opening of the second bag is distended elastically over the collar and the suspension means is substantially integrated with the walls and the first bag inflation orifice is accessible through the collar orifice.

Abstract
In a light duty punching bag and mounting arrangement, the bag is made from two balloons. A first balloon is inflated inside another, the two uniting to form a durable suitably resilient bag. Basis for suspension of the bag is a collar sandwiched between the walls of the two balloons and held there by a clamping force resulting from inflation pressure. Articulated connection to an overhead rebound board is by a short flexible tube and a ball pivot in tandem. These help produce a desirable rebounding characteristic, close to that of a professional punching bag. Several mounting methods are disclosed including at least one which provides a convenient height adjustment.

6. A punching bag for suspension when in use comprising:
-
an inflatable elastic bag, an elastic casing for surrounding the inflatable bag and having a wall and an opening in the wall; an adapter including a neck having an outer end and an inner end, and a skirt extending outwardly and substantially concentrically from the inner end; and
,in assembly, the adapter being inserted into the casing with the neck emerging from the casing opening and the bag being inserted into the casing, bag and casing being sized so that when the bag is inflated it distends the casing so that the skirt of the adapter is retained between bag and casing. - View Dependent Claims (7, 8, 9, 10, 11, 22)

12. A punching bag and suspension comprising, in combination:
-
a punching bag including an inflatable elastic bag and an elastic casing for enveloping the bag so that when the bag is inflated the casing is brought into intimate contact with the bag; a connecting collar including a connecting portion and a skirt portion depending from the connecting portion, the collar being disposed so that upon inflation the skirt is held between the bag and the casing and the connecting portion is directed generally radially outwards from the punching bag; a peg carried by the connecting portion and in assembly extending generally radially from the punching bag; a ball and socket pivot, including a ball having a radially extending peg and a socket for attachment in a depending relationship to a generally horizontal overhead surface, so that the ball may be retained in the socket with the peg extending downwards; and a flexible connecting element comprising a short length of elastic tubing having opposite open ends, the first and second pegs being insertable, one each in the opposite open ends of the tubing, tubing and pegs being sized so that the tubing grips the pegs sufficiently to maintain the punching bag connected to the overhead surface during normal punching bag operation. - View Dependent Claims (13, 14)

15. A punching bag and mounting comprising, in combination:
-
a punching bag including an inflatable elastic bag and an elastic casing enveloping the inflatable bag, so that when the bag is inflated the casing is distended and conforms to the shape of the bag; a platform for suspending the punching bag and having means for releasably mounting the platform on an upright surface; and articulated suspension means extending between the platform and the bag for swingably suspending the bag and including, in tandem arrangement, a swivel having a pivot center and a short normally linear flexible element. - View Dependent Claims (16)

17. A method of making a punching bag comprising the steps of:
-
procuring first and second similar balloons, each having an inflation neck defining an orifice; b. inserting a stiff collar having a central aperture into the inflation neck of the first balloon so that the orifice of the first balloon and the aperture of the collar register, and so that the wall of the balloon overlaps the collar; c. inserting the second balloon through the aperture of the collar; d. inflating the second balloon so that it distends the first balloon and so that inflation pressure is sufficient to secure the collar between the walls of the first and second balloons; and e. suspending the punching bag by connecting the collar to a fixed support. - View Dependent Claims (18, 19, 20, 21)
