Description

Bearing exercise system

Technical Field

The present invention relates generally to exercise systems, and more particularly to an elastic resistance exercise device that is adjustable to achieve different levels of resistance for weight training.

Background

The use of elastic resistance bands and machines utilizing such bands are well known in the weight training arts and provide a number of benefits. Elastic resistance bands are becoming more popular for athletic training, physical rehabilitation, and general fitness of people of all ages. Elastic resistance has many advantages, the most prominent being that the elastic band can create a resistance many times its weight, and it can flex to fit compactly into very small spaces. Thus, when one end of the elastic band is attached to a trainer and the other end is anchored to a stationary object or an opposing body part, the elastic band is a portable exercise device to provide resistance to the exercise of a human being. The resistance to weight ratio of the elastic band may be hundreds of times greater than the resistance to weight ratio of the metal weight plate.

The resistance provided by the elastic band may be increased by pre-stretching the elastic band. The shorter the belt is in its contracted state, the greater the percentage increase will be as a function of the distance of stretch. For example, if a 1 foot long, 1/4 inch thick elastic band is used and one end is anchored to the wall and the other end is held 11 inches to the wall, the elastic band will not provide resistance because the 12 inch elastic band is loose. However, if a 12 inch belt is stretched one hundred percent (100%) to 24 inches, the resistance will increase from 0 to about 10 pounds. If the belt is stretched to two hundred percent to 36 inches of a relaxed length of 12 inches, the resistance will increase by 150% to about 25 pounds, and so on. The resistance required to stretch the elastic belt may increase exponentially as the stretched length becomes a greater percentage of the relaxed length of the elastic belt. An exponential increase in resistance as a function of stretch distance is useful for many training applications.

Pearce teaches an exercise device in U.S. Pat. No. 9,192,802 that includes at least two resistance bands including a first shaft and a second shaft, each shaft having wheel assemblies rotatably connected at opposite ends thereof. The shaft is connected at each of the opposite ends by at least one of the resistance bands such that the device operates in rolling extension and retraction motions within the elastic region. The pedal assembly is axially coupled to the second shaft. The pedal/foot support assembly is capable of supporting and securing a person's feet so that the person can apply pressure when the person's hands grasp the first shaft and the person's feet push against the second shaft while moving in a substantially prone position.

Wehrell in US 9,802,072 teaches an elastic resistance exercise device for applying one or more lateral resistance loads to a participant to drive, swing and other phases while performing complex movements at low or high speeds to adjust the body to better and more quickly perform body movements at high speeds. The resilient member may be used to create resistance emanating from a ground-based or vertically positioned device. The elastic member may be attached to one or more body parts simultaneously. The device may be mechanically designed to fully retract the resilient member into the device when the participant is in close proximity to the device to maintain resistance. The device provides a plurality of individual resilient members and provides the participants with the ability to vary the vertical and horizontal position of each resilient member from the point of dispensing of the device. This provides the ability to control the resistance vector applied between the participant and the connection point on the device.

Detailed Description

The above figures illustrate the present invention, namely a weight bearing exercise system 10, wherein a user adjusts the distance between first pulley system 70 and second pulley system 72 to achieve different levels of resistance for weight training. The adjustable position of the system 10 provides an exponential increase in resistance as a function of the distance the elastic cord 60 is stretched.

Fig. 1 is a front perspective view of an exercise system 10 according to one embodiment of the present invention, showing a shroud 80 for protecting the internal components of exercise system 10. Fig. 2 is a rear perspective view thereof. As shown in fig. 1-2, exercise system 10 includes an elongated rigid housing 20 and an elongated extension arm 30. The elongate rigid housing 20 extends from a top end 22 to a bottom end 24, the bottom end 24 having a base structure 26 for supporting the elongate rigid housing 20 in an upright orientation. In this embodiment, base structure 26 also includes a plurality of flanges 27, flanges 27 having holes 28 for bolting exercise system 10 to a desired surface, but in other embodiments other methods of supporting system 10 may be implemented, such as retaining hooks, weights, support frames, and the like. The elongate rigid housing 20 also includes a delivery handle 53 and an adjustable mounting mechanism 40 having an adjustment handle 42, each of which will be described in greater detail below. The elongate extension arm 30 has a proximal end 32 and a distal end 34, the proximal end 32 being mounted to the bottom end 24 of the elongate rigid housing 20 via a pivot 36. As shown in fig. 1, the pivot 36 includes a folding mechanism 90 for pivoting the extension arm 30 toward the rigid housing 20 to terminate in a fully folded position (best shown in fig. 9). Extension arm 30 also has an arm pulley 38 rotatably mounted on distal end 34. The elastic cord 60 is fed through the rigid housing 20 and the extension arm 30 to a free end 62 at the arm pulley 38 of the extension arm 30, as will be described in more detail below.

In the embodiment of fig. 1, the feeding of the elastic cord 60 includes an exercise handle 64, which exercise handle 64 is connected to the free end 62 by a shackle 66 for performing exercises. In other embodiments, the elastic cord 60 may have other devices (e.g., a foot strap, a belt, etc.) connected to the free end 62. ) And may be connected to the free end 62 by any suitable means for connecting to exercise equipment, such as knots, hooks, handles, and the like.

As shown in fig. 2, the elongate rigid housing 20 includes a pair of laterally spaced channels 82 extending vertically on the elongate rigid housing 20, in this embodiment on a rear surface 84 of the housing 20. A plurality of locking brackets 86 are mounted on laterally spaced channels 82 for mounting exercise system 10 to a power frame. Support 86 also has an adjustment knob 88 for securing exercise system 10 to the power rack. Fig. 6-7 illustrate another possible method of mounting exercise system 10 to a powered support. Although these methods are shown, other attachment methods may be utilized to achieve the same effect, such as pins, straps, hooks, etc.

Fig. 3 is a front perspective view of exercise system 10 without sheath 80 shown to illustrate internal components. As shown in fig. 3, the elongate rigid housing 20 includes a pair of laterally spaced apart support frames 74 that house a first pulley system 70 and a second pulley system 72. The first pulley system 70 has at least one pulley and is rotatably mounted to the elongate rigid housing 20 at a fixed position adjacent the bottom end 24 of the elongate rigid housing 20. The second pulley system 72 has at least one pulley and is rotatably mounted on the adjustable mounting mechanism 40 such that the second pulley system 72 is movable relative to the first pulley system 70 to adjust the distance therebetween. The elastic cord 60 extends from the free end 62 to an anchored end 68, the anchored end 68 being attached to the top end 22 of the elongate rigid housing 20. The elastic cord 60 is fed back and forth between the first pulley system 70 and the second pulley system 72 and around the arm pulley 38 of the elongate extension arm 30. In this embodiment, elongate extension arm 30 further includes first and second guide pulleys 76, 78 at proximal end 32 for guiding elastic strand 60 therebetween, although in other embodiments, system 10 may use more or fewer guide pulleys.

The adjustable mounting mechanism 40, which moves the second pulley system 72, includes a mounting plate 44 fixedly mounted on the elongated rigid housing 20, the mounting plate 44 being connected to the rocker arm 46 by a pivot 48. The rocker arm 46 includes an adjustment handle 42 having a trigger release 50, the trigger release 50 controlling a locking tab 52 of the rocker arm 46. The locking projection 52 is adjustably engaged with a fixed arm 54 of the mounting mechanism 40. The securing arm 54 may have an arcuate shape and may include a plurality of locking notches 56, the locking notches 56 being shaped to receive the locking protrusions 52 of the swing arm 46 such that a user may grasp the adjustment handle 42 to move the swing arm 46 upward and position the locking protrusions 52 within the locking notches 56 to increase the distance and resistance between the first pulley system 70 and the second pulley system 72. Alternatively, the user may grasp the adjustment handle 42 and depress the trigger release 50 to withdraw the locking projection 52, which allows the swing arm 46 to move downward, thereby reducing the distance and resistance between the first pulley system 70 and the second pulley system 72.

Fig. 3 shows the adjustable mounting mechanism 40 in a first position, and fig. 4 shows the adjustable mounting mechanism 40 in a second position. Fig. 5 shows the third position and fig. 6 shows the fourth position. In this embodiment four locking notches 56 are shown, which means that there are four possible positions and thus four degrees of resistance of the elastic cord 60. However, in other embodiments, the adjustable mounting mechanism 40 may have more or fewer locking notches as desired by the manufacturer. Additionally, alternative methods of adjusting the distance between the first pulley system 70 and the second pulley system 72 may be applied, such as removable pins/latches, and the like.

Fig. 7 is a side view of exercise system 10 showing adjustable mounting mechanism 40 in a first position. Fig. 8 is a side view of exercise system 10 in a second position. In the first position of fig. 7, the first pulley system and the second pulley system are separated by a first distance D1. In this position, the resistance exerted by the elastic cord 60 is at a lower level for easier exercise. In the second position of fig. 8, the first pulley system and the second pulley system are separated by a second distance D2. In this position, the resistance exerted by the elastic cord 60 is at a higher level for more difficult exercises. As the distance increases at higher settings, a higher level of resistance is achieved. Although two distances are shown, it should be appreciated that each subsequent position of the adjustable mounting mechanism 40 will exhibit increased resistance.

Exercise system 10 may also include a gas spring 58 coupled to swing arm 46 and the elongated rigid housing for inhibiting movement of swing arm 46. In this embodiment, when the user wishes to lower the mounting mechanism 40, the gas spring 58 inhibits movement of the swing arm 46, thereby releasing the force of the elastic cord 60 so that the swing arm 46 does not suddenly move and strike down.

In another embodiment, the adjustable mounting mechanism may utilize alternative structures known in the art. Non-limiting examples include: any form of pivoting mechanism or swing arm having any form of adjustable locking structure known in the art; various forms of sliding adjustment mechanisms, rails, channels, etc., are known in the art; as well as other physical structures known to or devised by those skilled in the art.

Fig. 9 is a side view of exercise system 10 including a sheath 80 and in a fully collapsed state. As described above, the proximal end 32 of the elongate extension arm 30 is mounted to the bottom end 24 of the elongate rigid housing 20 by the pivot member 36. The pivot 36 includes a folding mechanism 90, the folding mechanism 90 for pivoting the extension arm 30 toward the rigid housing 20 to terminate in a fully folded position. In this embodiment, the folding mechanism 90 includes a locking spring 92 having a knob 94, the locking spring 92 being removably engageable with the proximal end 32 of the elongate extension arm 30. To fold exercise system 10 into the fully folded configuration, a user may pull knob 94, allowing extension arm 30 to pivot toward rigid housing 20. Knob 94 may be released to lock exercise system 10 in the collapsed configuration because locking spring 92 will bias folding mechanism 90 to the locked position. From this configuration, the user may further grasp a transport handle 53 mounted on elongate rigid housing 20 to facilitate transport of exercise system 10.

Fig. 10 is a perspective view of a second embodiment of a weight bearing exercise system 100 that includes at least one clip attachment mechanism 120 operably mounted on an elongated rigid housing 20. In this embodiment, the clip attachment mechanism 120 is movably mounted (e.g., slidably mounted) on the laterally spaced channels 82; however, in alternative embodiments, other mounting structures may be used. For example, in another embodiment, different mounting points may be provided for adjustable mounting of mechanism 120, rather than laterally spaced channels 82. In the previously described embodiment shown in fig. 2 and described above, a plurality of locking brackets 86 are mounted on laterally spaced channels 82 for mounting exercise system 10 to a power rack.

Fig. 11 is a top view of the clip attachment mechanism 120 shown in fig. 10. The clip attachment mechanism 120 of this embodiment includes an attachment base 122 slidably mounted on the laterally spaced channels 82. The attachment base 122 supports tapered clamps 124a and 124b, each clamp 124a and 124b being pivotally connected by a lever 126, the lever 126 allowing the clamps 124a and 124b to move laterally toward or away from each other to detachably clamp a second structure (not shown), such as a power rack. The tapered clamps 124a and 124b are sized and shaped to allow the clamp attachment mechanism 120 to fit within any size adjustment aperture of a standard power rack. A lever 126 may be hingedly mounted to each of the clamps 124a and 124b so that they may be grasped by a user to move between an open position and a closed position. In the open position, the lever 126 hinges outwardly, which allows the tapered clamp 124a, the clamp attachment mechanisms 120 and 124b to move apart from one another.

Once the weight bearing exercise system 100 has been positioned adjacent the power rack (not shown), the user may articulate the lever 126 to a closed position, wherein the tapered clamps 124a and 124b clamp the power rack (not shown) therebetween. The adjustable function of clamping mechanism 120 allows weight bearing exercise system 100 to be quickly, easily, and securely fastened to a wide range of power/squat stands as desired by the user.
