Similarly, moving the position of hinge 135 downward along first arm 115 decreases the maximum recline angle of first arm 115 .
- elastic resistance elements 126 may be adjustable.

Abstract
A resistance chair includes an elevated stationary seat with a front edge and a back edge. An arm is rotatably engaged with the back edge of the seat and is rotatable to a position below horizontal with respect to the elevated stationary seat. A back support is secured to the arm and supports the back of a user sitting on the elevated stationary seat. At least one resistance element is connected to the elevated stationary seat and urges the first arm to an upright start position and assists a user performing an abdominal crunch to return to an upright abdominal crunch position from a fully extended abdominal crunch position with the arm below horizontal with respect to the elevated stationary seat. The resistance element also resists against rotation of the arm away from the upright start position and resists against the user moving from the upright abdominal crunch position to the fully extended abdominal crunch position.
Description
- The following description relates generally to the field of exercise equipment and more specifically to the field of low impact abdominal exercisers.
- In an age of exercise and fitness, the time-honored abdominal crunch is under attack as potentially damaging if done incorrectly especially if performed by someone in poor physical condition. What is needed is an exercise tool to enable anyone to perform a correct abdominal crunch, and provide varying levels of resistance or assistance to accommodate people unaccustomed to exercise.
- Additionally, there is a need for an exercise tool that enables a user to perform alternative variations of the abdominal crunch. For example, traditional abdominal crunches performed on a flat surface such as the ground only allow a user to recline to a horizontal position. In order to increase the difficulty of a traditional abdominal crunch, it would be desirable to provide a device that allows a user to recline beyond a horizontal position while still ensuring that the user maintains proper form in order to prevent injury.
- The devices disclosed below satisfy these and other needs. The following simplified summary is provided in order to provide a basic understanding of some aspects of the claimed subject matter. This summary is not an extensive overview, and is not intended to identify key/critical elements or to delineate the scope of the claimed subject matter. Its purpose is to present some concepts in a simplified form as a prelude to the more detailed description that is presented later.
- A resistance chair with wheels assists users with performing correct abdominal crunches by guiding the user's effort and eliminating the initial jerking motion commonly experienced when doing an abdominal crunch. The resistance chair includes a seat connected to a hinged back with back support that extends to support the user's back and assist in the crunch recovery following the crunch extension.
- In operation, a resistance chair provides support for a user's back, adjustable resistance moving from the start position to the extended position thus exercising muscles that ordinarily don't receive work in abdominal crunches. The back support and the adjustable resistance of the resistance chair also assist the user by overcoming a portion of gravity to help the user perform a correct crunch moving from the extended position to the start position.
- By providing resistance to the backwards movement, the user engages the lower back muscles and thereby exercises the front and the back of the abdominal muscles. The backrest further permits core rotation providing the user the ability to do a sideways twist and engage the oblique muscles.
- In another embodiment, a resistance chair includes an elevated stationary seat with a front edge and a back edge. An arm is rotatably engaged with the back edge of the seat and is rotatable to a position below horizontal with respect to the elevated stationary seat. A back support is secured to the arm and supports the back of a user sitting on the elevated stationary seat. At least one resistance element is connected to the elevated stationary seat and urges the first arm to an upright start position and assists a user performing an abdominal crunch to return to an upright abdominal crunch position from a fully extended abdominal crunch position with the arm below horizontal with respect to the elevated stationary seat. The resistance element also resists against rotation of the arm away from the upright start position and resists against the user moving from the upright abdominal crunch position to the fully extended abdominal crunch position.
- In another embodiment, a resistance chair also includes a second arm having a first end and a second. An adjustable hinge is attached to the first arm and is movable between fixed locations along the first arm. The first end of the second arm is connected to the adjustable hinge and the second end of the second arm is connected to a roller, for example an axle with wheels. Moving the adjustable hinge along the first arm changes a maximum recline angle of the first arm. For example, moving the adjustable hinge upward along the first arm increases the maximum recline angle of the first arm, and moving the adjustable hinge downward along the first arm decreases the maximum recline angle of the first arm.
- To the accomplishment of the foregoing and related ends, certain illustrative aspects are described herein in connection with the following description and the annexed drawings. These aspects are indicative, however, of but a few of the various ways in which the principles of the claimed subject matter may be employed and the claimed subject matter is intended to include all such aspects and their equivalents. Other advantages and novel features may become apparent from the following detailed description when considered in conjunction with the drawings.
-
FIG. 1 is a rear perspective view of an alternative embodiment of a resistance chair with an elevated seat. -
FIG. 2 is a front perspective view of the resistance chair with an elevated seat ofFIG. 1 . -
FIG. 3 is a side elevation view of the resistance chair with an elevated seat of FIG. -
FIG. 4 is a front elevation view of the resistance chair with an elevated seat ofFIG. 1 . -
FIG. 5 is a side elevation view of the resistance chair with an elevated seat ofFIG. 1 , showing the arm rotated beyond horizontal with respect to the elevated seat. - In one aspect of the disclosed embodiments, an elevated resistance chair includes an elevated stationary seat. By elevating the seat, the user can recline to a position beyond horizontal relative to the seat because the ground (or other support surface) does not prevent the arm from rotating beyond horizontal with respect to the seat. This allows the user to perform more difficult variations of the abdominal crunch because a greater range of motion is permitted. The user's torso being in a position below the seat when in the fully extended abdominal crunch position requires the user to perform a more difficult abdominal crunch as the total range of motion is greater as compared to an abdominal crunch performed while seated on the ground.
- As shown in
FIGS. 1-5 ,resistance chair 100 includes elevatedseat 112. As opposed to the previously disclosed embodiments, it can be seen that elevatedseat 112 is spaced above the ground or other support surface upon whichresistance chair 100 is resting. One advantage of spacing elevatedseat 112 above the ground is that it allowsfirst arm 115 to recline to a position below horizontal with respect to elevatedseat 112. Thus,spacing seat 112 above the ground allowsfirst arm 115 to have a greater range of motion compared to a resistance chair in which the seat rests directly upon the ground rather than spaced above the ground. Elevatedseat 112 may be formed by providing a fabric ormesh panel 113 suspended byparallel arms 157 of U-shapedmember 156, as shown in the figures. U-shapedmember 156 also includesrear support member 158 spanning betweenparallel arms 157. Alternatively, elevatedseat 112 may be a solid flat member made from a suitable material such as plastic or metal. - To spaced elevated
seat 112 above the ground,front support legs 150 andrear support legs 152 are provided. Elevatedseat 112 is attached to these support rails near the upper ends offront support legs 150 andrear support legs 152. The attachment means may be fasteners such as bolts or screws, welding, adhesive, or any other suitable means.Front support legs 150 andrear support legs 152 may be inclined with their upper ends adjacent elevatedseat 112 and their lower ends spaced in front of and behind the front and rear edges of elevatedseat 112, respectively. By incliningfront support legs 150 andrear support legs 152 relative to vertical, greater stability of elevatedseat 112 is achieved. For example, if a user sitting on elevatedseat 112 leans or reclines backward, the incline ofrear support legs 152 will prevent elevatedseat 112 from flipping over. However, it is also contemplated thatfront support legs 150 andrear support legs 152 may be vertical. - In addition to
front support legs 150 andrear support legs 152,horizontal support rails 154 may be provided.Horizontal support rails 154 may be integrally formed withfront support legs 152 andrear support legs 154 as depicted in the figures. Alternatively,horizontal support rails 154 may be attached to the upper ends offront support legs 150 andrear support legs 152. Also alternatively,horizontal support rails 154 may be attached to or integrally formed with elevatedseat 112.Horizontal support rails 154 may be spaced above elevatedseat 112, as shown in the figures, or alternatively may be at the same level as elevatedseat 112. Additionally,horizontal support rails 154 may be splayed outward relative toparallel arms 157 of U-shapedmember 156, as depicted in the figures.Horizontal support rails 154 are gripped by a user sitting on elevated seat to help brace the user and perform abdominal exercises. -
Resistance chair 100 also includesfirst arm 115 andsecond arm 117.First arm 115 is hinged about its lower end athinge 114. At least oneshoulder support roller 125 is attached to the front surface of the upper end offirst arm 115 for rollably supporting the shoulders of a user sitting onelevated seat 112 and reclining againstfirst arm 115. Similarly, at least oneback support roller 124 is attached to the front surface offirst arm 115 below the upper end offirst arm 115 for rollably supporting the back of a user sitting onelevated seat 112 and reclining againstfirst arm 115. Althoughshoulder support roller 125 andback support roller 124 are advantageous because they facilitate sliding movement between the user's back andfirst arm 115 during abdominal exercises, they are not strictly necessary and may be omitted or replaced by non-rolling support members in some embodiments. - The upper end of
second arm 117 is hingedly connected tofirst arm 115 byhinge 135 which is attached to the rear surface offirst arm 115 adjacent the upper end offirst arm 115. As shown in the figures, hinge 135 may be spaced slightly below the ultimate upper terminus offirst arm 115. The lower end ofsecond arm 117 engages with a rolling device such asaxle 121.Second arm 117 may be integrally formed withaxle 121 as shown in the figures, but in other embodimentssecond arm 117 andaxle 121 may be formed separately and then attached to one another by welding, fasteners, or other suitable means.Axle 121 is rollably supported by rolling means such aswheels 122 that are rollably mounted on each end ofaxle 121. -
Axle 121 is hingedly connected to lowerresistance engagement elements 133. For example, as shown in the figures, lowerresistance engagement elements 133 may comprise sleeves that wrap aroundaxle 121 so that lowerresistance engagement elements 133 may rotate relative toaxle 121. Additionally, upperresistance engagement elements 134 are hingedly attached to the rear edge ofelevated seat 112. For example, as shown in the figures, upperresistance engagement elements 134 may comprise sleeves that wrap aroundrear support member 158 ofU-shaped member 156 so that upperresistance engagement elements 158 may rotate relative torear support member 158. Although a pair of lowerresistance engagement elements 156 and a pair of upperresistance engagement elements 158 are depicted in the figures, it is to be understood that there may be more or less than two of each of lower and upperresistance engagement elements - Spanning between lower
resistance engagement elements 156 and upperresistance engagement elements 158 areelastic resistance elements 126. In general, there will be the same number ofelastic resistance elements 126 as there are lower and upperresistance engagement elements resistance engagement elements 156, two upperresistance engagement elements 158 and twoelastic resistance elements 126. However, other configurations are also contemplated. For example there may be more or lesselastic resistance elements 126 as there are lowerresistance engagement elements 156 or upperresistance engagement elements 158 without departing from the general concept of the present disclosure. Examples of possibleelastic resistance elements 126 include rubber bands, resistance bands, springs or any other element that is elastic, resists against stretching and tends to return to its original length after stretching forces are no longer applied. - It can thus be seen that
elastic resistance elements 126 resist against reclining first arm 115 (i.e., a counter-clockwise rotation offirst arm 117 inFIG. 3 ). As most clearly shown inFIGS. 3 and 5 , asfirst arm 115 is reclined, the upper end ofsecond arm 117 is forced to rotate abouthinge 135 while the lower end ofsecond arm 117 simultaneously moves away fromelevated seat 112 due to the rolling ofwheels 122. This motion continues until reaching the fully reclined position depicted inFIG. 5 . Notably, in the fully reclined position ofFIG. 5 ,first arm 115 is reclined beyond horizontal with respect toelevated seat 112. Once the force causingfirst arm 115 to be reclined beyond the starting position depicted inFIG. 3 is no longer applied tofirst arm 115,elastic resistance elements 126 will pullaxle 121 back towardelevated seat 112. In general, the force provided byelastic resistance elements 126 is sufficient to returnfirst arm 115 andsecond arm 117 to the starting position depicted inFIG. 3 if there is no reclining force applied tofirst arm 115, but is not sufficient to lift a user from the fully reclined position ofFIG. 5 to the starting position ofFIG. 3 . In other words, the user must still use abdominal muscles to return to the starting position, but the force provided byelastic resistance elements 126 will assist the user's upward sit-up motion. - In alternative embodiments, one or more of the structures disclosed above may be adjustable in nature. For example,
first arm 115 orsecond arm 117 may be formed from two telescoping members with multiple apertures that are engageable with a locking pin. By telescoping the two telescoping members to a desired length and engaging the locking pin, a user can vary the length offirst arm 115 orsecond arm 117. Similarly, the location ofhinge 135 on the rear surface offirst arm 115 may be adjustable by slidinghinge 135 alongfirst arm 115 and securing the position with a locking pin that engages an aperture infirst arm 115. Adjusting the position ofhinge 135 varies the difficulty of exercises performed by modifying the starting angle betweenfirst arm 115 andsecond arm 117, and also by changing the starting position ofaxle 121 relative toelevated seat 112. It can be seen that moving the position ofhinge 135 upward along first arm 115 (i.e. away from elevated seat 112) allows for a greater maximum recline angle offirst arm 115 in the fully reclined position. Similarly, moving the position ofhinge 135 downward alongfirst arm 115 decreases the maximum recline angle offirst arm 115. Finally,elastic resistance elements 126 may be adjustable. For example, ifelastic resistance elements 126 are multiple resistance bands, it is possible to vary the resistance provided by disengaging one or more resistance bands from lowerresistance engagement elements 156 or from upperresistance engagement elements 158. - To use
resistance chair 100, a user sits onelevated seat 112 with his back and shoulders resting uponback support rollers 124 andshoulder support rollers 125 respectively. The user may grip one or both of horizontal support rails 154 with one or both hands, or not grip horizontal support rails 154 at all. A basic exercise the user can perform is an assisted extended sit-up. The user uses his abdominal muscles to push backwards againstfirst arm 115, a motion which is resisted against byelastic resistance elements 126 pulling against motion ofaxle 121 away fromelevated seat 112. The user continues reclining until any desired position is reached, up to the fully reclined position ofFIG. 5 . It should be noted that the fully reclined position ofFIG. 5 is not possible doing a standard sit-up on the ground with no equipment because the ground prevents the user's torso from reclining beyond horizontal. Once the desired reclined position is reached, the user may then complete the assisted extended sit-up by sitting back up until the starting position ofFIG. 3 is reached. The sitting up motion is assisted in this direction by contraction ofelastic resistance elements 126 which pullaxle 121 towardelevated seat 112.Resistance chair 100 can also be used for other exercises besides abdominal crunches. For example, the user can recline to the fully reclined position ofFIG. 5 and perform exercises such as scissor kicks, leg raises, sit and tucks, etc. In particular, it should be noted that these exercises can be performed with a greater range of motion than is possible while seated on the floor. For example, scissor kicks and leg raises can be performed with the users legs having a lowest position that is below horizontal and below the elevated seated of the device. - While the preferred embodiments of the devices and methods have been described in reference to the environment in which they were developed, they are merely illustrative of the principles of the inventions. Other embodiments and configurations may be devised without departing from the spirit of the inventions and the scope of the appended claims.
