A seat assembly associated with the support frame includes a seat which pivots about the first axis and is laterally and arcuately slidable about the second axis. The exercise device includes a footrest and a bar that attaches the footrest to the seat assembly such that the bar and the footrest pivot with the seat about the first axis.
Description
- The present invention generally relates to exercise devices. More particularly, the present invention relates to an abdominal exercise device having a lateral arcuately slidable seat.
- Exercise is an important part of a healthy lifestyle. A wide variety of exercise devices exist that provide cardiovascular exercise or resistance exercise to various muscle groups of a person's body. The look of a tight stomach is highly prized, especially among men who desire to have a well-defined abdomen in the form of a “six-pack” (in reference to the appearance of extremely well-defined abdominal muscles). In view of this, it comes as no surprise that included among the aforementioned exercise devices are a variety of abdominal exercise devices.
- In general, it is desirable for an abdominal exercise device to provide a user with more than one type of movement in order to exercise abdominal and other muscles. Prior to the existence of abdominal exercise devices, a person would perform a variety of different types of stand-alone exercises in order to develop his/her abdominal muscles. For example, the sit-up is a strength training exercise as well as one of the oldest and most basic of all the abdominal exercises. The sit-up works the entire rectus abdominis muscle wall although normally more stress is concentrated on the upper part verses the lower sections. To perform a sit-up, a person lies down on the floor with his/her knees bent at ninety degrees. The person then sits up without moving his/her knees. The person's hands are placed behind his/her head/neck or across his/her chest. The sit-up is intended to work the abdominal muscles, but the sit-up also utilizes the hip flexors and lower back. As some people desire to work only their abdominal muscles, the imprecise targeting of the abdominal muscles by the sit-up has caused sit-ups to be replaced by crunches as the most common abdominal exercise. The sit-up places considerable stress on the lower back vertebrae, so individuals who experience lower back pain should perform the crunch instead. The crunch is performed while lying face up on the floor with knees bent, by curling the shoulders up towards the pelvis. The hands may be placed behind the head, but care should be taken not to pull on the neck. Alternatively, the hands may be placed on the shoulders, with the forearms crossed over the chest. Unlike the sit-up, the lower back should not leave the floor. The difficulty of the sit-up and/or crunch can be increased by lying on a decline bench and/or holding a weight on the chest.
- A desirable feature of an abdominal exercise device provides for more than a single type of movement (e.g., lateral, longitudinal, pivotal, etc.) of the exerciser's body in order to mimic a wide variety of abdominal exercises, such as the sit-up, crunch or the like. Another desirable feature of such an exercise device is the ability to be adjusted to meet the physical characteristics of a wide variety of exercisers who vary from person-to-person in terms of body type, height, etc.
- Abdominal exercise devices have been used in professional gyms or fitness centers for many years. However, abdominal exercise devices designed for use in professional gyms or fitness centers have certain disadvantages when those abdominal exercise devices are used outside the setting of a professional gym or fitness center as these abdominal exercise devices can be large, cumbersome, limited in their versatility and are often difficult to operate, transport, and store. Such devices are also relatively expensive. While such devices are generally adequate in the fitness center or gym setting due to the large space available in such settings, such devices do not lend themselves to a household setting. For home use, the exercise device must not only be effective, but also compact and/or collapsible in order to easily transport and store the exercise device. The exercise device must also be relatively simple in operation and inexpensive.
- Devices for abdominal exercises are generally known in the art. For example, U.S. Pat. No. 6,379,289 discloses mid-section exercise apparatus with multi-axis capabilities. However, the disclosed device is not collapsible for easy portability or storage and the seat of the device is stationary, allowing only the upper portion of a user's body to move laterally. In another example, U.S. Pat. No. 5,334,120 discloses a gravity exercise machine that uses pulleys and ropes to connect to weights. However, the seat of the disclosed device does not move laterally or pivotally relative to the frame in order to provide muscle movement in a variety of directions. Another drawback is that the frame is not collapsible for easy transport and storage.
- As outlined above, various attempts have been made to overcome the limitations associated with previous abdominal exercise devices. However, as pointed out, some of these exercise devices have certain drawbacks in that the devices are not easily collapsible while others place unnecessary and dangerous strain and stress on the neck and back of the user of the device if the device cannot be adjusted to best suit the physical characteristics of a wide range of users. For example, the same exercise device should be able to be used by a very tall exerciser as well as a very short exerciser so that any size user can obtain optimum results from exercise. These devices also lack the ability to allow a user to move their body laterally while adjusting the relative angle between the user's legs and their torso. The ability to adjust the relative angle between the user's legs and their torso allows the user to perform a range of abdominal exercises including, without limitation, crunches. Also, for those individuals who travel and do not have access to a gymnasium in order to exercise, it is imperative that the exercise device be portable in nature.
- Accordingly, there is a need for an abdominal exercise device which is suited for home use that provides for both lateral and pivotal movement of a user's body, allowing the user to adjust the angle of their legs relative to their torso. Such an abdominal exercise device should be collapsible in order to be easily transported and stored, and also be relatively simple in operation and inexpensive. Preferably, such an exercise device should be adjustable in order to accommodate the size of the user of the device. The present invention fulfills these needs and provides other related advantages.
- The present invention resides in an abdominal exercise device having a lateral arcuately slideable seat. The abdominal exercise device is suited for home use, provides for both lateral and pivotal movement of a user's body, and allows the user to adjust the angle of their legs relative to their torso as well as adjust the device to the user's size. The abdominal exercise device is relatively simple to operate and is collapsible in order to be easily transported and stored. An abdominal exercise device embodying the present invention includes a support frame defining a first axis and a second axis. A seat assembly associated with the support frame has a seat which pivots about the first axis and is laterally and arcuately slidable about the second axis. In a preferred form, the second axis is generally perpendicular to the first axis.
- A footrest is associated with the seat assembly. A bar attaches the footrest to the seat assembly, wherein the bar and the footrest pivot with the seat about the first axis. A lock for holds the seat in one of a plurality of positions along the bar.
- The seat assembly includes a mechanism for rocking the seat relative to the bar. The rocking mechanism includes a track and roller assembly connecting the seat and bar. The seat arcuately rotates about the second axis and, in general, slides laterally perpendicular to the bar.
- A cradle is pivotally associated with the support frame and supports the seat for pivotal and rocking movement.
- The support frame comprises two ground-engaging sub-frames, and the seat assembly is pivotally disposed therebetween. Each set of ground-engaging sub-frames include a hinge whereby the ground-engaging sub-frame may be moved between an open position and a folded position. The hinge includes a lock for holding the ground-engaging sub-frames in the open position. A pair of handles extend from the support frame.

FIG. 14 is a cross-sectional view, taken generally along line 14-14 ofFIG. 12 . - As shown in the drawings for purposes of illustration, the present invention is concerned with an abdominal exercise device 20 (
FIGS. 1-3 ) that includes a ground-engagingsupport frame 22 and aseat assembly 24 having an arcuately-shapedseat 26 that is pivotally associated with theframe 22 about afirst axis 28 and, in general, laterally slidable with respect to theframe 22 about asecond axis 30. Thesecond axis 30 of the exercise device is perpendicular to thefirst axis 28 although thefirst axis 28 and thesecond axis 30 may be offset from one another. Theseat 26 may be made from a variety of materials including, but not limited to, wood, plastic or the like covered by a waterproof material with foam disposed between the hard base surface of theseat 26 and the waterproof material to provide padding for a user sitting on theseat 26. Theexercise device 20 also includes afootrest 32 associated with theseat assembly 24. - The
frame 22 comprises two ground-engagingsub-frames 34, and theseat assembly 24 is pivotally disposed between the two ground-engagingsub-frames 34. Each ground-engagingsub-frame 34 includes first andsecond legs hinge pin 40, whereby each of the ground-engagingsub-frames 34 may be moved between an open position (FIGS. 4 and 5 ) and a folded position (FIGS. 8 and 9 ). As shown inFIGS. 12-14 , a hinged member orlinkage 42 also connects the first andsecond legs sub-frame 34. Eachlinkage 42 is connected to the first andsecond legs pins linkage 42 includes twolinks pivot pin 52 located generally at the mid-portion of thelinkage 42 which allows theexercise device 20 to be folded for storage. Thelinkage 42 includes alocking mechanism 54 which is the same or similar to those used on conventional ladders. Thelocking mechanism 54 holds the ground-engagingsub-frame 34 in the open position by aflange 55 on the end of thelink 50 nearest thepivot pin 52 abutting against the top of thelink 48 when thelinkage 42 is in a linear configuration, theflange 55 of thelink 50 preventing thelinkage 42 from pivoting past a linear configuration in a first direction while allowing thelinkage 42 to move into a folded configuration in a second direction as theexercise device 20 is moved into a folded position. Alternatively, thelocking mechanism 54 comprises thepivot pin 52 of thelinkage 42 which only pivots between the linear and folded configurations. - A pair of
handles 56 are fixed with respect to theframe 22, each handle 56 being attached to an upper portion of thefirst leg 36 of the sub-frames 34. Each handle 56 has ahand grip 58 which gives the exerciser a firmer grip. The ground-engagingsub-frames 34 are connected by a cross-bar 60 extending between thefirst legs 36 of thesub-frames 34 towards the bottom portion of thesupport frame 22. - The
seat assembly 24 includes acenter bar 62 attaching thefootrest 32 to theseat assembly 24, wherein thebar 62 and thefootrest 32 pivot with theseat 26 about thefirst axis 28. Thefootrest 32 includes first and second foot bars 64, 66 upon which the user can rest a portion of his/her body (e.g., the heels of his/her feet, the soles of his/her feet, his/her legs, or the like) when exercising. Thefirst foot bar 64 is attached to the back side of, and disposed perpendicular to, thecenter bar 62. Thesecond foot bar 66 is attached to an end of, and disposed perpendicular to, thecenter bar 62. A user can use the foot bars 64, 66 either individually or in combination. For example, during exercise, a user can rest the heels of his/her feet on thefirst foot bar 64 while simultaneously resting the soles of his/her feet on thesecond foot bar 66. In another example, the user could rest the soles of his/her feet on either thefirst foot bar 64 or thesecond foot bar 66 during exercise. In yet another example, the user could rest the heels of his/her feet on either thefirst foot bar 64 or thesecond foot bar 66 during exercise. - As seen in
FIGS. 6 and 7 , theseat assembly 24 includes acradle 80 pivotally associated with the ground-engagingframe 22 and supporting theseat 26 where thecradle 80 rotates around thehinge pin 40. Thecradle 80 includes an arcuately-shapedcross member 82. Theseat assembly 24 includes amechanism 84 for rocking theseat 26 laterally relative to thebar 62. Therocking mechanism 84 includes a track androller assembly 86 connecting theseat 26 andbar 62. Theseat 26 arcuately rotates about thesecond axis 30 and, in general, slides laterally perpendicular to thebar 62. More particularly, theseat 26 is arcuately slidable about thesecond axis 30 as theseat 26 rocks back and forth along the track androller assembly 86. The track androller assembly 86 includes a firstarcuate track 88 attached byfasteners 90 to a bottom side of theseat 26, a secondarcuate track 92 formed on a bottom side of thearcuate cross member 82 of the cradle 80 (FIG. 3 ), and at least two pairs of roller sets 94. The roller sets 94 engage the firstarcuate track 88 to hold the firstarcuate track 88 in a position offset from the secondarcuate track 92 even as theseat 26 rocks from side-to-side. As the user sits on theseat 26, the weight of the user pushes the seat 26 (and the first track 88) against anupper roller 96 of each roller set 94 which then pushes alower roller 98 of each roller set 94 against thesecond track 92. This allows the user to laterally move theseat 26 in a rocking motion, from side-to-side of theexercise device 20. Neither of the roller sets 94 is able to travel past thecentral bar 62 which limits the distance theseat 26 is able to rock from side-to-side as the user exercises. - The
seat assembly 24 includes alocking mechanism 68 for holding theseat 26 in one of a plurality of positions along the length of thebar 62 by holding and/or releasing thebar 62 to move relative to theseat 26, as illustrated inFIGS. 10 and 11 . This allows the relative distance between theseat 26 and thefootrest 32 to be increased and/or decreased. Thelocking mechanism 68 includes a pair offlanges 70 located on, and extending downwardly from, a bottom portion of theseat assembly 24 and a plurality of bentflexible members 72, each including a pair of cylindrical posts orstubs 74, located within thehollow center bar 62. Eachstub 74, respectively, extends through oneaperture 76 of a plurality of pairs of aligned apertures 76 (i.e., theapertures 76 of each pair are located on opposite sides of thecenter bar 62 from each other). Thestubs 74 extend through theapertures 76 which located at a fixed point(s) on thecenter bar 62. Thestubs 74 also extend through respective alignedapertures 78 of theflanges 70. Theapertures 78 of theflanges 70 are aligned with each other. A user can move thefootrest 32 relative to theseat 26 by depressing thestubs 74 extending through theapertures 78 of theflanges 70. Once thestubs 74 are depressed so that thestubs 74 no longer engage theapertures 78 of theflanges 70, thebar 62 is moved relative to theseat 26, the interior surface of theflanges 70 maintains theposts 74 in depressed positions. Adjacent pairs ofstubs 74 are also depressed as thebar 62 moves relative to theseat 26 in order to allow theadjacent stubs 74 to engage the interior surface of theflanges 70. However, once a new pair ofstubs 74 become coaxial with theapertures 78 of theflanges 70, the force of theflexible member 72 pushes thestubs 74 through theapertures 76 that thestubs 74 are aligned with, locking thebar 62 in position relative to theseat 26. The process of depressing thestubs 74 to allow thebar 62 to travel relative to theseat 26 may be repeated until the desired distance between theseat 26 andfootrest 32 is achieved. In the alternative, thelocking mechanism 68 may use a turnable knob connected to a threaded shank that extends through theapertures 78 of theflanges 70 and one of a plurality of threaded bores along the length of thebar 62. The threaded shank is placed into the aperture 78 (which may be threaded) of one of theflanges 70 and then into a first opening of one of the plurality of threaded bores on one side of thecenter bar 62 and the knob is rotated in one direction until an end of the knob abuts against theflange 70 and/or when the threaded shank extends through the second opening of the threaded bore on the opposite side of thecenter bar 62 from the first opening and through theaperture 78 of theother flange 70. Turning the knob in the opposite direction until the shank is freed from theflanges 70 and threaded bore frees to thebar 62 to be moved relative to theseat 26. - In the alternative, the
exercise device 20 includes a mechanism to limit pivotal movement of thecradle 80 relative to the ground-engagingframe 22 and/or lock thecradle 80 in position so that thecradle 80 cannot pivot relative to the ground-engagingframe 22. - In use, a user opens the
exercise device 20 from a folded or collapsed, storage configuration to an open, use configuration by moving thelegs sub-frames 34 from the folded to the open positions by moving thelinkage 42 until thelocking mechanism 54 engages and maintains thelegs sub-frames 34 in an open position. The user then, in order to suit his/her individual height, adjusts the relative distance between theseat 26 and thefootrest 32 by moving theseat 26 to one of several positions along the length of thebar 62, as outlined in more detail below. The user then sits on theseat 26 of theexercise device 20. With each of his/her hands on one of the hand grips 58 of thehandles 56, the user pivots thecradle 80 until theseat 26 andfootrest 32 are at a desired angle relative to a surface of the ground theexercise device 20 is resting upon. In this manner, a user that maintains his/her torso in a generally vertical orientation relative to the ground is able to increase/decrease the angle between the user's legs and his/her torso. Maintaining this angle between the user's legs and his/her torso exercises the user's abdominal muscles. The user is also able to rock theseat 26, in the manner described above, in order to further exercise their abdominal muscles, as well as their oblique muscles, with the arcuately lateral movement of their pelvis relative to the generally vertical orientation of the user's torso, especially the upper torso, as theseat 26 travels in an arcuate manner with the aid of the track androller assembly 86. When a user is finished exercising, the user reverses the set-up process and collapses theexercise device 20 into a folded, storage configuration. - The above-described embodiment of the present invention is illustrative only and not limiting. It will thus be apparent to those skilled in the art that various changes and modifications may be made without departing from this invention in its broader aspects. Therefore, the appended claims encompass all such changes and modifications as falling within the true spirit and scope of this invention.
