This application claims the benefit of priority of Israeli Patent Application No. 289472, filed 28 Dec. 2021, entitled “EXERCISE BAR FOR PILATES EQUIPMENT”, which is incorporated herein by reference in its entirety.
The present invention relates generally to exercise equipment. More specifically, the present invention relates to an exercise bar for Pilates equipment.
Pilates is a physical fitness system developed in the early 20th century by Joseph Pilates, after whom it was named. Practicing Pilates includes performing controlled movements, which improve flexibility, build strength, and develop control and endurance in the entire body. A Pilates Cadillac, springboard or tower/wall units are Pilates equipment that includes a bed/excessive bench with springs, ropes, and pulleys. Some Pilates equipment also includes vertical frames. A typical vertical farm may include, two push-thru springs, two roll-down springs with a horizontal roll-down bar, two-arm springs with foam grip handles, two leg springs with padded long spine straps, two extension straps, two traveling spring hooks, two traveling pulleys, and a safety chain.
The horizontal roll-down bar is a rigid swingable bar that allows the trainee to swing the bar up and down with both hands simultaneously while laying or sitting on the exercise bench/bed. Although, equipped with many types of equipment Pilates Cadilac do not include equipment that can mimic swimming movement while providing resistance that can mimic the resistance of water.
When training trainees after head injuries (e.g., following a stroke) it is beneficial to work simultaneously on both sides of the body while providing each side of the body with a different exercise, and forcing the brain to train the uninjured side and the injured side, separately. Even healthy trainees when working together with both hands/arms or both legs will find that the dominant side of the body works harder than the non-dominant side of the body, as this is the “easier” choice of the brain. Allowing each side of the body to work differently at the same time (e.g., doing opposite movements such as in freestyle swimming) may force the weak limb to train.
Accordingly, there is a need for an exercise bar, that can train both sides of the body, for example, the arms, simultaneously while performing different movements.
Some aspects of the invention are directed to an exercise bar, comprising: a shaft; a first rigid handle unit rotatably connected to the shaft at a distal end of the first rigid handle unit; a second rigid handle unit rotatably connected to the shaft at a distal end of the second rigid handle unit; a grip connected to a second end of the at least one arm; and a handles lock, wherein the handles lock has an unlocked state in which each of the first and second rigid handle units is free to rotate around the shaft independent of the other, and a locked state in which the first and second rigid handle units are rotatable together and at a same direction around the shaft. In some embodiments, each rigid handle unit comprises at least one arm rotatably connectable to the shaft at a first end of the arm.
In some embodiments, the handle lock comprises at least one connector, detachably connecting the first rigid handle unit to the second rigid handle unit. In some embodiments, each of the arms comprises at least one hinge, configured to allow rotation of at least a portion of the arm, around an axis parallel to the shaft. In some embodiments, each arm further comprises an arm lock configured to prevent rotation of the at least portion of the arm, when in a locked position, and to allow rotation when in an unlocked position. In some embodiments, the at least one hinge is configured to allow 360° rotation around the axis parallel to the shaft. In some embodiments, each arm comprises at least one piston for adjusting the distance between the hinge and the shaft.
In some embodiments, the exercise further comprises a distance-adjusting mechanism for adjusting the distance between the first rigid handle unit and the second rigid handle unit. In some embodiments, the first rigid handle unit and the second rigid handle unit are slidable on the shaft and wherein the distance adjusting mechanism comprises a first latch for locking the first rigid handle unit at a first location on the shaft and a second latch for locking the second rigid handle unit at a second location on the shaft while allowing rotation of the first and second rigid handle units.
In some embodiments, the shaft is connectable to a support element. In some embodiments, the support element is connectable to an exercise bench. In some embodiments, the shaft is at least 50% longer than the width of the exercise bench.
The subject matter regarded as the invention is particularly pointed out and distinctly claimed in the concluding portion of the specification. The invention, however, both as to organization and method of operation, together with objects, features, and advantages thereof, may best be understood by reference to the following detailed description when read with the accompanying drawings in which:

In some embodiments, handles lock 40 may include at least one connector 45, as illustrated, detachably connecting first rigid handle unit 20 to second rigid handle unit 30. Handles lock 40 may detachably connect arms 25 at any location along the arms, for example, at the middle of the arms, at ⅔ of the length of the arms from shaft 10, as illustrated, and the like. In some embodiments, handles lock 40 may detachably connect a first grip 26 to a second grip 26. In some embodiments, handles lock 40 may include any locking mechanism configured to detachably connect two rigid elements to each other, for example, handles lock 40 may include, one or more movable pins and corresponding holes for receiving the pins, clamps, and the like. It should be appreciated by those skilled in the art that handle lock 40 may be connected to one of handle units 20A (and 20B), or may be a separate element that when connected to handle units 20 (, 20B) locks the handle units together and when removed, releases handle units 20A (and 20B) to move independently with respect to each other, around shaft 10.
In some embodiments, exercise bar 100 may further include one or more springs, not illustrated, detachably connected between shaft 10 and any one of rigid handle units 20A and/or 20B (e.g., detachably connected to the proximal end of arms 25) for providing resistance to the rotation movement of the handle units to enhance the exercise.
Reference is now made to
In some embodiments, each of the arms 25 may comprise at least one hinge 27, configured to allow rotation of at least a portion 25A of the arm, around an axis x2 parallel to the axis x1 and shaft 10, as illustrated. In some embodiments, each arm may include two portions, a first portion 25A and a second portion 25B, and wherein at least one hinge 27 is configured to allow 360° rotation of the first portions around the axis parallel to shaft 10. In some embodiments, hinge 27 may be located at the connection between first portion 25A and a second portion 25B.
In some embodiments, each arm 25 may further comprise an arm lock 29 configured to prevent rotation of the first portion (e.g., portions 25A) of the arm, when in a locked position, and to allow rotation when in an unlocked position. In some embodiments, the lock may include any locking mechanism that may allow locking the first portion with respect to the second portion.
In some embodiments, each arm 25 may comprise at least one piston 28 for adjusting the distance between hinge 27 and shaft 10. In some embodiments, piston 28 is included in second portion 25B.
In some embodiments, each one of first and second rigid handle units 20A and/or 20B may include a single arm 25, two arms 25 forming a U shape, as illustrated, three arms or more. In some embodiments, exercise bar 200 may further include a handles lock, such as handles lock 40 included in exercise bar 100 of
In some embodiments, exercise bar 200 (and also exercise bar 100) may further include a distance adjusting mechanism 15 for adjusting the distance ‘D’ between first rigid handle unit 20A and second rigid handle unit 20B. For example, the distance D can be set to work at the shoulder's width, as illustrated in
In some embodiments, handle units 20A and 20B are slidable on shaft 10 and wherein the distance adjusting mechanism comprises a first latch for locking the first rigid handle unit at a first location on the shaft and a second latch for locking the second rigid handle unit at a second location on the shaft. In some embodiments, the first and second latches may allow handle units 20A and 20B to freely rotate around shaft 10 while maintaining the distance D between the two handle units. For example, the distance adjusting mechanism may include a set of replaceable flexible spacers (e.g., springs) having different lengths corresponding to the different required distances D. The replaceable flexible spacers may connect distal ends 22 of arms 25 to each other while allowing a relative movement between the two arms.
In some embodiments, shaft 10 is connectable to a support element 50. In some embodiments, support element 50 may be connectable to a wall using wall element 52, to a floor using floor element 54, and/or to an exercise bench illustrated in
In some embodiments, exercise bar 200 may further include one or more springs, not illustrated, detachably connected between shaft 10 and any one of rigid handle units 20A and/or 20B (e.g., detachably connected to the proximal end of arm portions 25B, or to grips 26) for providing resistance to the rotation movement of the handle units to enhance the exercise.
Reference is now made to
In some embodiments, in order to mimic freestyle swimming using exercise bar 200, handle units 20A and 20B and arms 25 should be in unlocked positions and the distance D between handle units 20A and 20B should be wider than the shoulder's width of the trainee. In this arrangement, a trainee laying on his stomach on bench 60 holding grips 26 may perform a movement that mimics the freestyle swimming. Connecting arms 25 to shaft 10 with springs may provide resistance to the movement that may mimic the resistance of water.
Exercise bar(s) according to embodiments of the invention may allow exercising/training each part of the body separately or simultaneously doing different movements. For example, each one of the arms may perform opposite movements, such as swinging grips 26 in opposite directions. In yet another example, each arm can be trained under different intensity, when only one arm 25 is connected by a spring to shaft 10, thus forcing one side of the body to work harder than the other. This may be beneficial when training trainees after strokes, where there is a need to strengthen the injured side.
Therefore, an exercise bar according to embodiments of the invention may allow training a trainee in ways that cannot be achieved using any known equipment.
