TITLE
EXERCISE AND PLAY HOOP
FIELD OF INVENTION
The present invention relates to play and/or exercise hoops.
BACKGROUND
Play hoops, often referred to as "hula hoops", for rotation about the body are widely known, and used for gyrating around the hips and other parts of the body. These hoops are typically made from a length of plastic tubing having a circular cross-section. The tubing is shaped in a circle and the ends are joined to form the hoop. Decoration is commonly provided with colored plastic and colorful patterns.
Many people have difficulty learning to use these types of hoops. This can be for a variety of reasons but inevitably the circular hoop slips down past the user's hips and falls to the ground. The process can be frustrating, particularly for the beginner.
SUMMARY OF INVENTION
The present invention is directed to a play and/or exercise hoop. In one general aspect, a play and/or exercise hoop includes an inner wall having a top edge and a bottom edge and an outer wall having a top edge and a bottom edge. The bottom edge of the outer wall is attached to the bottom edge of the inner wall to define a bottom edge of the hoop. A rounded top-portion is attached to the top edge of the inner wall and a top edge of the outer wall.
Embodiments may include one or more of the following features. For example, a first plane defining the surface of the inner wall and a second plane defining a surface of the outer
wall are at an angle relative to a central axis of the hoop. The inner wall and the outer wall define a v-shaped configuration extending from the bottom edge of the hoop to the attachment with the rounded top-portion.
The inner wall of the hoop may have a high friction surface that makes contact with the user thereby helping to prevent the hoop from slipping down the body of the user.
The hoop may be a continuous circle made from a tube segment that is joined together. Thus, it may typically be hollow.
The hoop may have an iridescent film or transparent film bonded to its outer surfaces.
The inner wall and/or the outer wall may be flat and angled relative to a central axis of the hoop. The angle of the inner wall creates increased surface area and additional friction between the hoop and the user. By "flat", what is meant is a surface which is flat in cross-section even though curved about the hoop.

DETAILED DESCRIPTION OF EMBODIMENTS
Referring to FIGs. 1 - 4, a hoop 100 includes a rounded top portion 102 that is attached to an inner wall 104 and an outer wall 106 that converge to a V-shaped bottom edge 108. The hoop is formed from a length of tubing that is bent into a circular shape and the two ends joined (not shown).
FIG. 2 is a side view of the hoop 100 showing the rounded top portion 102, the outer wall 106 and the V-shaped bottom edge 108. FIG 3 is a cross-sectional view of the hoop 100 along the line A- A of FIG. 1. The rounded top portion 102 is attached to the inner wall 104 that converges to the bottom V-shaped edge 108. Referring to FIG. 6, the inner wall 104 and the outer wall 106 have a dimension of approximate ¾ of an inch as shown by Dimension B. In other embodiments the inner and outer walls 104, 106 may have dimensions ranging from 0.5 - 1.0 inches. As shown, the hoop is hollow, however, in different embodiments the inside of the hoop may be a solid composition or may be filled with solid matter, such as, for example, water or a counter weight.
FIG. 4 is a perspective view of the hoop 100 with the V-shaped edge 108 facing up and the rounded portion 102 facing down.
The hoop 100 is formed from a semi-rigid plastic, such as, for example, extruded polyethylene or polyethylene terephthalate glycol, the latter being a type of thermoplastic polyester. The thickness of the hollow hoop 100 may depend on a desired weight and amount of rigidity. The diameter of the hoop 100 may range from 32 - 39 inches for youth or advanced adult hoopers. Mid-size hoops 100 may be approximately 36 - 42 inches in diameter. Large hoops 100 are typically 42 inches or larger. However, the diameter of the hoop can vary significantly based on the height and ability of the user. Typically, hoops 100 may weigh from about 0.2 to 2.5 pounds.
Referring to FIG. 5, the user can grab around the ergonomic V-shape of the hoop 100 and rotate it around her hips. The user continues the momentum of the hoop by moving her hips and midsection in a front to back, side to side or push-pull motion which maintains the hoop in a circular motion.
As shown in FIG. 6, the inner wall 104 rides along the user's hips. In the embodiment as show, the inner wall 104 is flat instead and angled to mate with a larger area of the user's hips, there is additional surface friction between the user and the inner flat wall 104 of the hoop. The surface friction may also be enhanced with a roughened surface, a fabric, friction tape and/or rubberized hemispherical bumps bonded to the inner flat wall 104 (not shown).
In another embodiment as shown in FIG. 7, the inner wall 104 and the outer wall 106 have a slight curve relative to the top portion 104 thereby defining a tear drop cross-sectional view. Once again, the tear drop shape of the inner wall 104 creates more surface area in contact with the body of the user. Referring to FIG. 8, a connector 112 is used to attach the two ends of a segment of tubing to form the hoop 100. The connector has a first end 114 and a second end 116 and a rib 118 between the first and second ends 114, 116. The two ends of a tube segment are pushed onto the first and second end 114, 116 and butt up against the rib 118. The ends 114, 116 are then bonded or glued in place.
A decorative iridescent film may be bonded to the outside of the hoop. The iridescent film is transparent so that it accents or enhances the base color of the hoop.
The above description of various embodiments reveals the general nature of the invention so that others can readily modify and/or adapt for various applications other embodiments without departing from the concept, and, therefore, such adaptations and modifications are within the scope of the claims and equivalents. The terminology used herein is for the purpose
of description and not of limitation. The means, materials, and steps for carrying out various disclosed functions may take a variety of alternative forms without departing from the invention.
