DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION
[0069] Referring now to the drawings, wherein similar parts of the preferred embodiment of the Hand Held Exercise Device 10A and 10B (wherein the detailed description of JOB in is shown beginning with FIG. 12) are identified by like reference numerals, there is seen in FIG. 1 a perspective view of a person holding two of the preferred embodiments of the Hand Held Exercise Device 10A with one in his left hand 12 holding the handle 14 massaging his left shoulder with the spherical head 16 and the other in his right hand 18 holding the handle 14 in an upright position. Lanyards 20 are illustrated going around the wrists and attached through an orifice 22 in the grip end 24 of the handle 14.
[0070] FIG. 2 depicts a perspective view of an exploded view of the preferred embodiments of the Hand Held Exercise Device 10A illustrating the reinforcing ribs 26 in the handle 14 with the mounting screw orifices 28 where the mounting screws 30 secure the two halves of the handle 14 together. Two additional mounting screw orifices 28 are located in the spherical head retainers 32 that locate within the two depressions 34 on either side of the head insertion section 36 of the spherical head 16. The handle 14 may be constructed with an over-molded rubberized grip surface, and that rubberized grip surface may be comprised of thermoplastic rubber (also known as TPR). Other rubberized sleeves and grips can alternatively be used in place of over-molded material.
[0071] In this embodiment, two halves of the handle portion fasten together to form one elongated handle that locks the flexible club head portion to the handle portion via locking grooves. In one embodiment, the two halves define a cylindrical handle. In one embodiment, the two halves are longitudinal halves that extend for the entirety of the handle length.
[0072] One of the advantages of having the entire handle portion made of two halves instead of having a single piece handle is that an over-molded thermoplastic rubber can be more easily applied during the manufacturing process to each handle portion individually rather than to a singular elongated handle.
[0073] Another advantage of having the handle portion made of two halves that come together to form single handle is a reduction in the number of pieces that may be required to fasten the flexible club head portion to the handle portion in a similar manner to using locking grooves.
[0074] FIG. 3 depicts a cross section through the preferred embodiments of the Hand Held Exercise Device 10A illustrating the orifice 22 for the lanyard 20 in the grip end 24 of the handle 14. A polarity of reinforcing ribs 26 extend through the central portion 38 of the handle 14. Four mounting screw orifices 28 are the locations where the mounting screws 30 hold the two halves of the handle 14 together. The spherical head 16 consists of an outer shell 40 that can be manufactured by, but not limited to a rotational molding process with a flat surface 42 on the spherical end so that the device can stand upright and the head insertion section 36 at the other end. The insertion section 36 is held within the two halves of the handle 14 by the means of the two depressions 34 on the opposing sides being locked in place by the means of the two spherical head retainers 32 on both inside surfaces of the handle 14. Additionally a circumferential rib 44 at the distal end of the handle 14 locks into the circumferential groove 46 at the edge of the insertion section 36 of the spherical head 16. The central cavity 48 of the spherical head 16 is partially filled with a granular material 50. At the upper end of the head insertion section 36 is a tubular orifice 52 for the purpose of installing a variety of materials into the central cavity 48 and will be sealed with a plug 54. With regard to contemplated dimensions, the proportion of the club head diameter in relation to the widest portion of the handle at the attachment location may be in the ratio of 2:1, as shown here in FIG. 3. For example, if the club head diameter is approximately 6 inches, then the fluted upper portion of the handle at the attachment location would be approximately 3 inches.
[0075] FIG. 4 depicts a front view of the of the spherical head 16 of the preferred embodiments of the Hand Held Exercise Device 10A further illustrating the locations of the two depressions 34 on the opposing sides of the head insertion section 36.
