Definitions

  • the present invention relates generally to exercise devices.
  • the present invention relates more specifically to suspension devices and acrobatic apparatus where the user may hang freely by short handles, bars, or rings.
  • the present invention relates more specifically dual ring suspension exercise devices that are adjustable in height.
  • rings or handles hanging from a ceiling or elevated apparatus is common in exercise classes where the user is suspended from the rings or handles to perform pull-ups, muscle-ups or other body weight exercises.
  • Other exercises also performed on the rings such as L-sits, where the user holds an acrobatic body position in which all the body weight rests on the hands with the torso held in a slightly forward leaning orientation, with legs held horizontally so that each leg forms a nominal right angle with the torso. The right angle causes the body to have a notable L shape to it.
  • the rings For pull-ups the rings must be higher off the ground than for L-sits. Often the rings must be adjusted to certain common heights for different exercises during the same workout session. For example, eight feet for pull-ups and three feet for L-sits.
  • One method to adjust the rings to different heights involves ridged arms, where the straps are attached to the rings at one end and the rigid arms above. The structure is elevated and adjusted up and down as desired. Such a device is typically expensive and requires a higher ceiling for adjustment because the length of the suspension straps is not adjusted. They remain at fixed lengths while the rigid arms are raised up to elevate the rings.
  • a different method which is the most common method for mounting and adjusting rings and handles to the ceiling, uses a simple setup which is a strap looped over the ceiling rafter and through the ring. The height of the rings is adjusted using a cam buckle attached to one end of the strap and the loose end of the strap is clamped in the cam buckle to adjust for the desired length. There are two main problems with this method.
  • the first being the extra strap is hanging in the way of the user and presents a hazard.
  • the strap can become tangled on the user’s foot and injure them when the user dismounts the rings.
  • the typical method to counteract the problem of the extra strap is to take the time to neatly roll it up and tie it to the rafters or at least up and out of the way. This takes a good bit of time and must be done in between different exercises.
  • the present invention is primarily used in suspension training where the device will be attached to a ceiling or frame that keeps the device from moving and allows the user to hang on the device partially supported or fully supported by the device.
  • the primary use of the device is physical training.
  • the benefits of the device of the present invention include allowing the user to quickly adjust the height or length of the straps of the device by pushing a button or pulling on a lever to release a locking mechanism and then pulling downward on the straps.
  • the straps are spring loaded and will retract into the device when the locking mechanism is released.
  • the dual straps adjust at the same time as they are wound on the same spool. This makes the device of the present invention simpler than similar devices that may require separate strap control.
  • the preferred embodiment that uses a cam lock mechanism that directly engages the straps makes the device stronger than similar systems.
  • the present invention provides a device that supports rings that are suspended from an elevated structure.
  • the device adjusts quickly, accurately, and automatically coils extra strap out of the way of the user.
  • the frame of the device supports a cam buckle, a spinning spool that is spring loaded with a power spring to retract the dual straps.
  • the device is generally mounted about nine or ten feet above the exercise surface. Fully extended the rings attached to the end of the strap can be adjusted all the way to the ground to facilitate exercises near the ground such as ring supported pushups.
  • the spool spins about a shaft that is attached to the frame.
  • a power spring is wound about the same common shaft.
  • One end of the spring is attached to the spool and/or shaft while the other end is attached to the frame.
  • the spring is at its minimum size and maximum tension.
  • the cam buckle is disengaged the spring retracts and rotates the spool winding up the straps.
  • the straps are fully wound up the spring is at its maximum diameter and minimum tension.
  • the features of the device from top to bottom are; a mounting hook, the spool assembly with the straps leading out and down through the lock mechanism (cam buckle) that is located below the spool on the frame. The ends of the straps are then attached to gymnastic rings or handles.
  • Fig. 1 is a profile view of a preferred embodiment of the present invention shown with a number of optional control cords, the device shown in a generally retracted condition prior to being extended for use.
  • FIG. 2 is a side view of the preferred embodiment of Fig. 1 with the reel component of the present invention exposed for clarity, the device again shown in a generally retracted condition prior to being extended for use.

  • Fig. 1 is a profile view of a preferred embodiment of the present invention shown with a number of control cords, the device shown in a generally retracted condition prior to being extended for use.
  • Strap suspension device 10 is generally comprised of reel frame and enclosure 12 and power retraction spring and enclosure 14.
  • Reel frame and enclosure 12 is coaxial with and supports power retraction spring and enclosure 14 having a common reel and spring axel 16. The manner in which these two components interact with each other is shown in more detail below in Fig. 3.
  • Reel frame and enclosure 12 is suspended from hook hanger 18 on hanger pivot 20.
  • Hook hanger 18 may be structured as a wide curved plate or as a curved rod.
  • Hanger 18 is used to hook over and hang from a ceiling joist, a pull up bar, or any other elevated horizontal structure to support the device of the present invention.
  • the hanger is preferably secured to an immobile structure although in some situations it may be suspended from a free-swinging rope, chain, or other vertical line.
  • Reel frame and enclosure 12 is a generally circular structure with a lower extension that houses the locking mechanism of the device.
  • lock mechanism lever 22 and lock mechanism pivot 24 can be seen.
  • the internal structure of one embodiment of the locking mechanism of the present invention is shown in detail below in Fig. 4.
  • Extending from this lower portion of reel frame and enclosure 12 are first strap 26a and second strap 26b. Although these straps 26a & 26b are reeled onto the single retraction reel together, they are not otherwise attached to each other along their entire length. This allows the two handles 28a & 28b to be drawn apart as far as may be required for use.
  • the only limitation on the separation of the two handles 28a & 28b, and the two straps 26a & 26b, is the length or distance they are extended from the device 10.
  • the locking mechanism of the present invention is designed to restrict movement (up or down) when the lock mechanism is engaged.
  • the cam structure of the locking mechanism prevents further extraction of the straps from the device.
  • the residual pressure within the closed locking mechanism is sufficient to resist the retraction force of the retraction spring until the user releases the lock mechanism.
  • the user controls the lock mechanism by pulling on release cord pull 32 at the lower end of lock mechanism release cord 30.
  • the upper end of release cord 30 is attached to the end of lock mechanism lever 22 and serves to rotate lever 22 around lock mechanism pivot 24 to remove pressure on the straps 26a & 26b. Again, this functionality is described in detail below in Fig. 4.
  • the user of the device of the present invention may begin by releasing the lock mechanism as described above, and then simply grasping the handles 28a & 28b to pull them down to the desired height.
  • the lock mechanism is then released (set in place) which prevents further extraction of the straps from the device.
  • Other means for retrieving the handles (or rings) are envisioned such as having a pole with a hook on the end to retrieve the handles or rings.
  • FIG. 2 is a side view of the preferred embodiment of the present invention shown in Fig. 1, with the reel component exposed for clarity, the device again shown in a generally retracted condition prior to being extended for use.
  • Strap suspension device 10 is again shown to be comprised of reel frame and enclosure 12 and power retraction spring and enclosure 14.
  • reel frame and enclosure 12 is coaxial and connected with power retraction spring and enclosure 14, again having a common axel 16.
  • Reel frame and enclosure 12 is pivotally attached on hanger pivot 20 to hook hanger 18.
  • hook hanger 18 is structured as a wide curved plate suitable to be hooked over and hung from a pull up bar or the like.
  • the hanger is preferably secured to an immobile structure although in some situations it may be suspended from a free-swinging bar or other horizontal rod or pipe.
  • Reel frame and enclosure 12 is a generally circular structure with a lower extension that houses the locking mechanism of the device.
  • Fig. 2 shows the internal components of reel frame and enclosure 12 rotatably positioned between parallel back and front plates that support reel and spring axel 16.
  • lock mechanism lever 22 and lock mechanism pivot 24 can be more clearly seen as well as the manner in which the lock mechanism contacts straps 36a & 36b.
  • the internal structure of one embodiment of the locking mechanism of the present invention is shown in greater detail below in Fig. 4.
  • Reel and spring axel 16 extends from one wall of the enclosure 12, through strap reel spool 17, through the second wall of enclosure 12, through retraction spring 19, and finally through the outer wall of spring enclosure 14.
  • Axel 16 rotates freely through each enclosure wall (preferably with one or more bearings or slip rings) and is rotationally fixed to the center of strap reel spool 17 and retraction spring 19 to connect the two and to function in the manner shown in Fig. 3.
  • first strap 36a and second strap 36b Extending from the lower portion of reel frame and enclosure 12 are first strap 36a and second strap 36b. These straps 36a & 36b are distinct from those shown in Fig. 1 only to the extent they terminate with rings 38a & 38b instead of handles.
  • the user controls the lock mechanism by pulling on release cord pull 32 at the lower end of lock mechanism release cord 30.
  • the upper end of release cord 30 is attached to the end of lock mechanism lever 22 and serves to rotate lever 22 around lock mechanism pivot 24 to remove pressure on the straps 36a & 36b.
  • This functionality is described in greater detail below in connection with Fig. 4.
  • FIG. 3 is a schematic diagram of the reel components of the present invention showing the manner in which the dual straps are wound together on the reel and the rewind spring positioned next to and coaxial with the dual strap reel.
  • the strap reel is shown apart from the retraction spring to show the manner in which extraction of the straps 26a & 26b from the reel (rotation direction “A”) rotates the reel and spring axel 16 to tighten (rotation direction “B”) the retraction spring 19.
  • rotation direction “A” the manner in which extraction of the straps 26a & 26b from the reel
  • spring axel 16 to tighten
  • the retraction spring 19 As long as the lock mechanism is set, the straps remain extracted (unwound) from the reel spool.
  • the retraction spring rotates the reel spool in the opposite direction thereby reeling up the dual straps back into the enclosure.
  • Fig. 4 is a detailed cutaway view of one preferred embodiment of the dual strap locking mechanism of the present invention.
  • the lower portion of reel frame and enclosure 12 is shown to define a channel through which the dual straps pass together.
  • Straps 26a & 26b may separate as shown.
  • Straps 26a & 26b are loosely held between a fixed block and cam lock pressure block 23 as they exit enclosure 12.
  • Cam lock pressure block 23 is positioned to channel the straps out of the enclosure and to oppose the force of cam lock 23 that is movably positioned on the opposite side of straps 26a & 26b.
  • a cam lock 23 pivots around lock mechanism pivot 24 as moved by the movement of lock mechanism lever 22 when the user pulls on lock mechanism release cord 30.
  • the lock mechanism shown in Fig. 4 is but one example of the manner in which the straps on the reel spool may be immobilized or released.
  • Other mechanisms, controlled by the user with the lock mechanism release cord 30, may be fixed within the reel frame and enclosure 12 to achieve the same manner of control.
  • Mechanisms that act to contact the reel spool (for example), as opposed to directly on the straps, could be set or released by the user with the lock mechanism release cord 30.
  • Any mechanism connected to the pull cord on one end, and preferenced (as by a spring or weight) to move in the opposite direction when no downward pull on the cord is made, can interact with the straps, the reel, or even the axel, to alternately lock or free the straps to raise or lower.
  • lock mechanisms that act on the reel and/or the axel may likewise incorporate structures whereby the retraction spring force assists with the release of the lock mechanism when the release cord is pulled.
  • lock mechanisms associated with the reel and/or axel may include sprocket elements with a tooth that engages the sprocket to stop it and the connected reel/axel from spinning.
  • Such a device could also include a flat disc fixed with the reel/axel with holes around the perimeter and a moveable shaft attached to a button that engages the disc to stop the motion. None of these modifications or variations in structure are seen to depart from the spirit and scope of the present invention.
