Description
Field of the Invention
This invention relates to weightlifting, and more particularly to an arm locking device worn during weightlifting exercises to enhance the benefits of certain arm exercises.
Background of the Invention
In recent years, weightlifting has become a popular and useful means of physical exercise, not only for bodybuilders, but also athletes involved in man other sports. These include professional and college athletes who use weightlifting exercises for building strength and for physical conditioning. Football and basketball players and track and field athletes perform a variety of weightlifting exercises to keep in top shape. Football players especially use certain specific weightlifting exercises to build mass as well as strength. With the recent emphasis on weightlifting as a useful means of exercise and physical conditioning, a variety of lifting devices have been developed for isolating the effects that the weightlifting has on the body so as to magnify the intensity of each exercise. In this way, strength or mass can be developed for the particular muscle groups more effectively and in a shorter amount of time.
One such weightlifting device is used by weightlifters performing arm exercises for the biceps, such as curls. This device includes a curved rigid bar made of metal or plastic which fits over the weightlifter's chest. The bar is held in place by an adjustable neck band. The ends of the bar extend outwardly from opposite sides of the body, behind the elbows. The back portions of the weightlifter's arms (the triceps regions of the upper arms) rest against the ends of the rigid bar. The ends of the bar can have a slight curvature to conform to the back of the arms to hold them in place, spaced apart from the sides of the body during use. When performing weightlifting exercises such as curls, the ends of the rigid bar act as a restraint to resist the forces applied during the exercise. This device attempts to keep the arms in place and eliminate cheating which can occur if the elbows drift away from the sides of the body and thereby make it easier to lift the weight. By preventing cheating, the effect of the lifting exercise is isolated on the biceps and helps develop these muscles faster. These previous arm locking devices suffer from several disadvantages. The wide rigid bar which fits over the lifter's chest digs into the chest when the ends of the bar resist the force of the weight during use. This causes painful pinching of the skin and uncomfortable pressures on the front of the chest. In addition, the lifter's arms often are not constantly held in place on the ends of the rigid bar. There is a tendency for the elbows to move outwardly when performing weightlifting exercises such as curls, and they can slip off the ends of the bar. This device also is not designed well for use by women.
The present invention provides an arm locking device for weightlifters which overcomes the disadvantages of the prior arm locking device and which also provides additional improvements in accomplishing the desired results of certain arm exercises.
Summary of the Invention
Briefly, one embodiment of this invention provides an arm locking device for use by weightlifters which includes an elongated flexible and foldable strap which is substantially non-stretchable in its axially dimension. The strap has a central portion for overlying the chest region of a weightlifter; a left end portion long enough to wrap around the left arm of the weightlifter by extending between the chest and left elbow, behind the left triceps and over the left biceps and then to an overlapping position on the central portion of the strap; and a right end portion long enough to wrap around the right arm of the weightlifter by extending between the chest and right elbow, behind the right triceps and over the right biceps and then to an overlapping position on the central portion of the strap. Fastening means on the central portion of the strap are attached to cooperating left and right fastening means on the left and right ends of the strap for holding the left and right end portions of the strap in fixed positions wrapped around the left and right arms of the weightlifter. The strap being wrapped around the left and right arms of the lifter in this way holds the left and right arms of the weightlifter in a locked position with the fastened ends of the strap keeping the elbows of the left and right arms in close contact with the sides of the body, by resisting outward movement of the left and right arms during weightlifting exercises.
The flexibility of the strap makes it possible to perform weightlifting exercises such as curls without creating any resistance to the normal lifting action, and the ends of the strap being wrapped around the lifter's biceps cooperate with the force of the weight being lifted to naturally resist any tendency of the elbows to drift away from the body during use. The strap can be adjusted to hold the arms in contact with the sides of the body during use. As a result, the effect of the weightlifting exercises can be isolated on specific muscle groups and the result of the weightlifting exercise is enhanced.

Detailed Description
FIG. 1 illustrates a front elevation view of an arm locking device 10 for weightlifters according to principles of this invention. FIG. 2 illustrates the opposite side of the arm locking device shown in FIG. 1. As illustrated in these figures, the arm locking device includes an elongated flexible and foldable strap 12 which is substantially longer than its width and is preferably of uniform width from end to end. The strap is preferably made from a heavy duty woven nylon fabric so that the strap is flexible and foldable but is also axially stiff or essentially nonelastically stretchable in its axial direction. In one embodiment the strap 12 is approximately 52 to 56 inches long and has a width approximately 21/2 to 31/2 inches wide A preferred length is 54 inches and a preferred width is about three inches. Referring to the rear elevation view of FIG. 2, the elongated strap 12 preferably comprises a central region 14, a right end region 16, and a left end region 18. Each of these three sections of the strap extends for approximately one-third the total length of the strap. In an preferred embodiment the central region and each of the left and right regions is approximately 18 inches long.
A pair of elongated continuous narrow friction fasteners 20 and 22 are secured to the entire length of the central region 14 of the strap. These fasteners 20 and 22 are preferably secured so that they extend parallel to one another immediately inboard the upper edge and lower edge of the strap. In a preferred embodiment the frictional fasteners comprise a pile type of Velcro material.
An adjustable neck loop 24 is also secured to the central region 14 of the strap. The neck loop includes a long strap 26 extending upwardly away from the central region of the strap generally perpendicular to the top edge of the strap. The long neck strap 26 is rigidly fastened to the strap 12 by rows of stitching 28. The neck loop also includes a short neck strap 30 also extending perpendicularly away from the upper edge of the strap 12. The lower portion of the short neck strap 30 is rigidly affixed to the strap 12 by rows of stitching 32. The long and short portions 26 and 30 of the neck strap are preferably secured to the outer face of the strap 12 between the strap 12 and the overlying Velcro fasteners 20 and 22. The long neck strap 26 is sufficiently long to extend from the strap 12 and around the neck region of the weightlifter and then extend toward the short portion 30 of the neck strap to an adjustable ring fastener 34. This fastener adjusts the length of the loop formed by the long and short portions 26 and 30 of the neck loop. The ring fastener 34 is conventional. The resulting neck loop is adjusted to the size of the weightlifter and generally is sufficiently long so that the central region 14 of the strap 12 can overlie the chest region of the weightlifter during use, generally in the region of the biceps, with the loop extending upwardly and behind the weightlifter's neck for stabilizing the central portion 14 of the strap 12 in a generally horizontal position across the chest.
The right end portion 16 of the strap 12 includes a pair of short, continuous, elongated friction fasteners 36 and 38 These fasteners are preferably made from parallel strips of a Velcro hook type material, and these fastener strips extend parallel to one another immediately inboard the right end 40 of the strap 12. In one embodiment they extend for approximately six inches in length. At the opposite end of the strap 12, a pair of upper and lower elongated continuous friction fasteners 42 and 44 extend parallel to one another immediately inboard the left end 46 of the strap 12. In a preferred embodiment the fasteners 42 and 44 at the left end of the strap are also about six inches in length and comprise strips of velcro hook material.
FIGS. 3 and 4 illustrate use of the arm locking device. The central region 14 of the strap 12 is placed over the front of the chest region of the user and is stabilized on the chest region by first placing the adjusted neck loop 24 around the neck of the weightlifter. The left end portion 16 of the strap 12 is then wrapped around the left arm of the weightlifter, by extending the left end of the strap behind the left arm, i.e. between the left side of the chest and left elbow, behind the left triceps and then around the outside of the left arm and around the front of the biceps, with the left end portion of the strap then extending to an overlapping position on the central region 14 of the strap 12. Similarly, the right end portion 18 of the strap is wrapped around the right arm of the weightlifter by passing the right end of the strap between the right side of the chest region and the right arm, behind the right triceps and around the right arm, over the front of the right biceps, with the right end portion of the strap overlapping the central portion of the strap 12. The Velcro fasteners 36 and 38 at the right end of the strap are affixed to right end portions of the Velcro fasteners 20 and 22 that face outwardly from the central region of the strap. Similarly, the Velcro fasteners 42 and 44 at the left end of the strap are affixed to the left end portions of the cooperating Velcro fasteners 20 and 22 on the central portion of the strap. Once the strap is wrapped around the arms and then the ends of the straps are tightly affixed by the frictional fasteners so that the strap firmly holds both arms in contact with the sides of the body so as to prevent any significant outward movement of the elbows away from the sides of the weightlifter's body. This means of attachment is best illustrated schematically in FIG. 4 which shows a right loop 48 and a left loop 50 formed by the right and left end portions of the strap, respectively, as they fit around the right and left arms 52 and 54 of the weightlifter. This attachment of the arm locking device, being in the biceps region of the arms, leaves the forearms entirely free from any restraint so that arm exercises such as curls can be preformed without any resistance caused by the arm locking device. The strap 12 being substantially inflexible in length resists any tendency of the elbows to drift away from the sides of the weightlifter's body during use. Because of the flexibility of the strap, any pressure applied to the body from weightlifting exercises does not create discomforting pressure on the chest or arms of the weightlifter; while the loops 48 and 50 which extend entirely around the biceps regions resist any tendency for the arms to move outwardly and remain rigidly fixed in place against the sides of the body (because of the axial inflexibility of the strap) during the exercise. Thus, the weightlifting exercise can be isolated on specific muscles because of this means for controlling the positions of the arms during use. In addition, the flexibility of the arm locking device makes it possible for use by women weightlifters and also makes it possible for the device to easily be folded into a small size to be easily carried in a gym bag.
