Brief Patent Description - Full Patent Description - Patent Application Claims
PRIORITY [0001] This application claims the benefit of priority of Provisional Application 60/630,211. BRIEF DESCRIPTION OF THE INVENTION [0002] This invention relates generally to exercise equipment and more particularly to an improvement in exercise equipment which provides an improved approach to physical fitness, sports conditioning, training, rehabilitation, etc. [0003] Heretofore, exercise equipment tended to be specialized and limited in their use. For example, a solid bar with suitable collars located at the two opposite ends is typically used only for working out with only free weights. Equipment that provided for increased resistance to certain movement was limited, with a series of devices needed for a complete body workout. [0004] The present invention is an exercise core bar that, as will be explained, permits the user greater flexibility in selecting the particular exercises and further provides the opportunity to work with different muscle groups when compared to known equipment. BRIEF DESCRIPTION OF THE FIGURES [0005] FIG. 1 is an illustration of an exercise bar with a weight retaining collar removed for clarity; [0006] FIG. 2 is an enlarged illustration of the handle end of the exercise bar shown in FIG. 1; [0007] FIG. 2A is a further enlarged illustration of the handle end of the exercise bar; [0008] FIG. 3 is an enlarged illustration of the second end of the exercise bar shown in FIG. 1; [0009] FIG. 4 is a further enlarged illustration of the second end of the exercise bar including a weight retention collar; [0010] FIG. 4A is a further enlarged illustration of the second end of the exercise bar including a weight retention collar; and [0011] FIG. 5 is an enlarged view of the second end of the exercise bar with a free weight held in place on the second end by the removable collar. DETAILED DESCRIPTION OF THE INVENTION [0012] The exercise core bar will now be described in greater detail. As illustrated in the FIG. 1, the exercise bar includes an elongated rod 1 having at least two ends, made of material selected from fiberglass, plastic, wood, rubber, or metal, for example, steel, iron, chromoly, aluminum, magnesium, titanium, die cast metal, etc. [0013] It may have length from one end to the other end that can range from, for example, one foot (30 cm) to four feet (180 cm). It can have a circular cross-section diameter of about 1 inch, but can range from 1/2 inch (2.5 cm) to 2 inches (5 cm). The foregoing measurements, together with other measurements, shapes and dimensions that will be discussed, are to be considered illustrative and not limiting. [0014] The core bar can be covered with a layer of rubber, leather, or plastic or be completely exposed. It can be given a textured surface, such as knurling. The bar can be hollow or solid. The bar can vary in size over its width. Its shape can be straight, or curved, for example, in zigzags or curved. The cross sectional geometry of the bar can include a circle, a triangle, a rectangle, or other multi-sided pattern. [0015] The core bar can be collapsible from a fully extended position to modify its length or taken apart for ease of transportation. The means for extending and collapsing of the bar includes well known means, such as twist-locking, screw-on, etc. See U.S. Pat. No. 6,925,686, or Heathcock, et al. or U.S. Pat. No. 5,372,558, Perry et al., which are hereby incorporated by reference. [0016] A first end of the exercise bar can have an integral or separate handle 2. The handle can be various shapes including a rod, a sphere, an "L," a "T," an "O," and "I," a "D" or any type typically found on shovels. The handle can be constructed using webbing, chain, metal, plastic, wood, rubber, etc. FIG. 2 illustrates one example of a desired handle. The handle can be removable or permanent. The handle includes a first portion to be gripped by the hand of the user and a second portion which attaches to the rod. [0017] The means used to attach the handle to the rod can include any known method for attaching two objects together. Preferably the second portion of the handle is in the form of a hollow socket for receiving a first end of the rod. When the handle is attached to the rod, the socket on the handle surrounds the first end of the rod such that the handle is rotatably mounted onto the rod. The first end of the rod can include an interior threaded socket which receives a bolt. The bolt extends through the first portion of the handle and is threaded into the socket in the rod first end. [0018] The handle shape can be similar to a letter "D" with the curved portion attached to both ends of the straight portion, such as by screws or alternatively welded to the straight portion of the "D" portion of the handle. The straight portion of the handle may be covered by a replaceable grip made of padding, rubber or other non-slip material. The length (axial dimension) of the handle is not considered part of the length of the bar, as set forth above. [0019] Referring next to FIGS. 3, 4, 4A and 5, the second end of the bar includes weight retention means 3 that can include a weight retention sleeve 4. The size of the sleeve can range from about is approximately 2 inch diameter which is compatible with standard Olympic size weight plates 7, and can range from 1/2 inch (1.75 cm) to 2 inches (5 cm). It can also have a conventional removable collar 5. [0020] One end of the sleeve terminates in a flange of preferably 3 inch diameter which serves as a retention and support for any weight plates placed on the bar. When a weight is placed on the weight retention sleeve and the collar thereafter inserted onto the sleeve, the weights do not slide along the bar toward the first end. The weight retention sleeve and collar may have a total axial length of about 6.25 inches, but can have a range of between 4 inches (10 cm) to 24 inches (60 cm).
