Illustrative Embodiment
FIGS. 1 and 2 illustrate one embodiment of the invention. As shown the exercise bar 10 is composed of a frame 18 having a pair of rails 14 and having distal ends 18a, 18b. A weight loading surface 15 is positioned at both ends of the frame 18. Typically, users will load weights or weigh plates onto surface 15, which is not shown but well known in the prior art. A pair of handles 11 are engaged with and ride upon the pair of rails 14 comprising the frame 18 as shown in the illustrative embodiments as illustrated by FIGS. 1-5. The each end of the rails 14 terminate at an angled portion 19 which connects to the end of the frame 18 and the weight loading surface 15. As shown in FIGS. 1-4 the angled portion 19 is at angle of approximately forty-five degrees in relation to the frame ends and rails but other angles may be selected based on the preference of the designer or fabricator without departure from the scope of the present disclosure.
Other embodiments, not shown, may have a frame 18 constructed with a pair of handles 11 riding on a frame comprised of a single rail by one of ordinary skill without departure from the spirit of the disclosure. Also, as one of ordinary skill will appreciate, the frame 18, pair of rails 14, moveable handles 11 and weight loading surfaces may be constructed from any one of a number of materials including steel, aluminum and or plastic, without limitations, solely dependent on the best means of production, fabrication and the preference of the user 17. As shown, each moveable handle 11 has a user grip 12 and a first and second end 11a, 11b. As one of one skill will appreciate, the moveable handles 11 and user grip 12 may be configured with knurling or padding (not shown), dependent upon user preference, and incorporate other geometries or configurations, without departure from the spirit of the disclosure. The handle as shown has a plurality of grips 12 including without limitation two that are parallel with the pair of rails (12b, 12e), one that is perpendicular with the pair of rails (12a) and one that is angled (12d) in relation to the pair of rails.
As exemplified by FIG. 5, a user may choose to engage the exercise bar handle in a multitude of grip positions (12a-12e) to perform different exercises engaging different or additional muscles. For example, and without limitation, a user 17 may move their grip to position 12e to perform an exercise similar to a hammer curl to target the brachioradialis while allowing for working of the synergistic brachialis and biceps brachii muscle groups. This same exercise will also work the stabilizing muscle groups such as and including the deltoids (anterior), trapezius (upper and middle) as well as the levator scapulae, flexor carpi radialis and extensor carpi radialis. One of ordinary skill will appreciate then that user 17 may grip the other positions 12a, 12b, 12c and 12d of the handle during exercise and some or all of the muscles discussed to the benefit of the user and solely as preferred by the user.
As exemplified by FIGS. 3-5, a pair of spring assemblies 13 is used to generate additional tension upon the user increasing the load or stress on the user's muscles during movement of the moveable handles 11 along the pair of rails 14 of frame 18. FIGS. 1-5 illustrate that each spring assembly 13 is composed of a loop portion 13a affixed at one end of handle 11. As shown, the loop 13a is affixed between the top and bottom of the handle (11a, 11b), respectively. (See FIG. 2) This is but one way to attach this loop 13a as will be obvious to one of ordinary skill. A first end of the tensioning member 13b is then connected to the loop 13a. The second end of the tensioning member 13c is affixed to the inside of the weight loading surface 15, which is illustrated as a tubular or cylinder like structure. This is but one way to attach the spring assembly 13 between the handle 11 and the end of the frame 18 as will be obvious to one of ordinary skill. As will be obvious to one of ordinary skill, the spring assembly 13 shown is but one means by which to place load upon the handles 11 as they move along the frame 18. Other springs and tension systems will be obvious to one of ordinary skill in the art. Although not shown, a threaded cap may be positioned at the distal end of the weight loading surface 15 to which the second of the tensioning member 13c may be affixed allowing removal and replacement or repair of the tensioning member.
Illustrative Method of Use
The illustrative method of exercising as disclosed herein comprises positioning a weight (not shown) on either end of a frame 18, illustrated herein as weight loading surface 15. Engaging a user 17 with a grip portion 12 located on the handle 11 positioned interior the frame ends (18a, 18b). An exercise movement is then initiated from a first position (illustrated at FIG. 3) in substantially a first direction with concurrent movement of the handles 11 from a first position during the exercise movement in a direction substantially perpendicular to the first direction and then terminating the exercise movement in a second position (illustrated at FIG. 4) wherein the moveable handles 11 are also in a second position. One of ordinary skill will appreciate from the preceding description that the handles 11 moving in the first direction placed a load on each spring assembly 13 as the handle 11 traveled from the outer portion of frame 18 to the inner portion on rails 14.
In the exemplary exercise depicted in FIGS. 3-5, users swing the weight up towards their chest in a curling motion, the moveable handles allowing the users grip to move in a transverse manner to the direction of travel (inward or outward) along the frame. This transverse movement during the upward movement may also be under tension, to produce additional beneficial stress to the user's muscles, as previously discussed.
Having described the preferred embodiments, other features of the exercise bar and method of use will undoubtedly occur to those versed in the art, as will numerous modifications and alterations in the embodiments as illustrated herein, all of which may be achieved without departing from the spirit and scope of the exercise bar 10 and/or method of use. It should be noted that the exercise bar 10 and method of use are not limited to the specific embodiments pictured and described herein, but are intended to apply to all similar apparatuses and methods for putting a physical load on a user during exercise for the purpose of generating muscle adaptations. Modifications and alterations from the described embodiments will occur to those skilled in the art without departure from the spirit and scope of the exercise bar 10 and/or method of use.
