DESCRIPTION OF THE PREFERRED EMBODIMENT AND BEST MODE

Referring now specifically to the drawings, an adjustable hand weight assembly according to the present invention is illustrated in FIG. 1, and shown generally at reference numeral 10. The hand weight assembly 10 is highly versatile, and especially applicable for convenient use at home or when traveling.

As best shown in FIGS. 1-5, the hand weight assembly 10 comprises a relatively thin and generally disk-shaped base weight 11 having a top 12, bottom 14, opposing sides 15 and 16, and opposing outside major surfaces 17 and 18. The outside major surfaces 17 and 18 define a respective front and back of the base weight 11. An integrally-formed handle 20 extends outwardly from the base weight 11, generally parallel to the front and back 17, 18. Preferably, the handle 20 has a comfortable, textured grip 21 spaced from the top 12 of the base weight 11 and formed of a cushioned slip-resistant material, such as neoprene or other natural or synthetic rubber. According to one embodiment, the overall thickness of the base weight 11 is between 2 and 3 inches. The base weight 11 is preferably made available in a wide variety of weights ranging from between 2.5 and 20 pounds (lbs).

For added versatility, the sides 15, 16 of the base weight 11 have respective contoured neoprene grip areas for holding the weight assembly 10 with both hands during exercise. A through-bore 24 is also formed with the base weight 11 to facilitate handling.

Referring now to FIGS. 6-8, the base weight 11 preferably comprises an open, recessed weight cell 25 designed for receiving and holding a separate add-on weight plate 30. The add-on plate 30 has an outside perimeter flange 31, a generally annular inner periphery 32, and hand openings 33 and 34. The hand openings 33, 34 facilitate handling and allow convenient usage of the add-on plate 30 by itself separate from the base weight 11, if desired.

For use in combination with the base weight 11, the add-on plate 30 comprises locking tabs 35 and 36 which extends radially inward at the inner periphery 32, and which aligns and mates with a mounting track 40 located within the weight cell 25 of the base weight 11. The mounting track 40 has notches 41, 42 through which the locking tabs 35, 36 pass (See FIG. 7) upon application of the add-on plate 30 to the base weight 11. As best illustrated in FIGS. 7 and 8, after application, the add-on weight 30 is rotated clockwise into the mounting track 40 as indicated at arrow 44 such that the locking tabs 35, 36 locate behind respective holding walls 46, 47 of the mounting track 40. This secures the add-on weight 30 to the base weight 11. Additionally, the base weight 11 preferably has a spring-loaded, depressable detent 51 located within the weight cell 25 and adapted for entering into one of two complementary holes 52, 53 formed with the add-on plate 30. Upon mating alignment of the detent 51 and selected hole 52, 53, the base weight 11 and add-on weight 30 are releasably locked together to form a single weight unit. Preferably, the add-on plate 30 resides entirely within the weight cell 25, and does not project outwardly from either the front 17 or back 18 of the base weight 11.

To release the add-on plate 30, the spring-loaded detent 51 is depressed and the plate 30 rotated counterclockwise to realign the locking tabs 35, 36 and notches 41, 42 formed with the mounting track 40. Once aligned, the plate 30 is easily removed from the weight cell 25. Like the base weight 11, the add-on plate 30 is preferably made available in a wide variety of weights ranging from between 2.5 and 10 pounds (lbs).

For convenient storage and transport, the weight assembly 10 is preferably located in a portable carrying case 60 illustrated in FIGS. 9 and 10. The carrying case 60 has rigid top and bottom halves 61, 62, and divided interior compartments 64 for separately storing several base weights 11 and add-on plates 30 of different weights. The top and bottom halves 61, 62 are pivotably attached together along adjacent side edges, and have complementary closures 65, 66 located on opposite side edges for closing the case 60. Preferably, the top and bottom halves 61, 62 are formed a highly durable PVC or other molded plastic. To facilitate transport, the carrying case 60 also has a pair of wheels 67 and an extendable handle 68. When the case 60 is closed, as shown in FIG. 10, the top surface 69 of the top half 61 forms a step applicable for certain muscle training and aerobic conditioning. Alternatively, the top half 61 may be removed from the case 60 and used by itself as an exercise step. The top surface 69 is preferably textured and comprises a slip-resistant rubber covering.

An adjustable hand weight assembly and carrying case are described above. Various details of the invention may be changed without departing from its scope. Furthermore, the foregoing description of the preferred embodiment of the invention and best mode for practicing the invention are provided for the purpose of illustration only and not for the purpose of limitation—the invention being defined by the claims.
