Definitions
- the present invention generally relates to exercise equipment such as exercise bikes, including an exercise bike having an adjustable ground support so that the bike may be safely ridden by larger and/or taller riders.
- Exercise bikes have become increasingly popular in recent years. This has included exercise bikes that may be used either at home or in a gym setting.
- Exercise bikes that simulate outdoor riding are a particularly effective way for users to obtain a total body workout and provide an enjoyable ride that retains the rider's interest.
- Such bikes allow the rider to place his or her hands on different areas of the handlebar and also allow the rider to adopt different riding positions, such as sitting and standing. This allows the rider to simulate the experience of riding on hills, riding across flat terrain and other riding conditions.
- Such bikes have generally become known as indoor cycles. Because they are ridden in different positions, such bikes need to have a strong and stable frame and also need to provide stability to the rider.
- Existing devices may allow for some adjustability in order to account for differently sized riders or users.
- these devices have various shortcomings and/or do not allow an indoor cycle ride that simulates outdoor riding conditions, including riding in sitting and standing positions.
- U.S. Pat. No. 8,409,060 to Hsu entitled “Exercise Bike for Rehabilitation” discloses a device for rehabilitation.
- the device includes a movable base that allows the user to adjust the distance between the seat and the handlebars of the device. While the adjustable base may accommodate users of different heights, it does not address the need for providing extra stability that may be necessary for taller or larger riders. Furthermore, this device is not at all intended to allow the rider to ride in different positions to simulate outdoor bike riding conditions in which vigorous riding could cause the device to tip in the first place.
- U.S. Pat. No. 5,971,894 to Chen entitled “Stationary Exercising Bicycle” discloses an exercise device with a movable base.
- the purpose of the movable base in this device appears to be to raise or lower the seat for users of different heights. However, it does not appear that movement of the base is intended for increased support for larger or taller riders.
- the device looks inherently unstable and top heavy, and has many rotating joints that would appear prone to failure.
- this device does not does not allow riding in different positions and does not appear to address instability that could be caused by vigorous riding of a tall or heavy person.
- U.S. Patent Application Publication 2012/0295770 A1 to Lo discloses an exercise device with a movable base. But in this device, the base is movable to accommodate sitting and lying positions. The base is not designed to provide structural support for larger users. In addition, the device is not designed to simulate an outdoor bicycle ride where the rider may stand up and sit down or address associated instability.
- adjustable support bars may provide additional structural support, such as U.S. Pat. No. 5,439,433A to Lunden.
- this device is a step climber and is not at all an exercise bike that may allow the rider to simulate outdoor bike riding conditions.
- the adjustable support bar appears limited to the situation where the step climber wants to shift his or her weight to the rear of the steps on which the user stands. It provides no lateral stability or protection against tipping from side to side.
- a versatile and adjustable exercise bike that has an adjustable support that may accommodate larger and taller riders so that they may safely ride the bike.
- this bike to provide a ride for a heavy or tall rider that simulates outdoor bike riding conditions, such as riding in alternating sitting and standing positions.
- the adjustment mechanism may be easily and cleanly adjusted by the rider.
- the current invention addresses the foregoing issues and provides an improvement over existing devices.
- the exercise bike is configured to accommodate a variety of different sized riders, including riders who may be heavy, large and/or tall.
- the bike includes a frame that may adjust to provide more stability so that larger and taller riders may safely ride the bike.
- the frame may include an adjustable base that may be extended to provide a larger footprint on the ground and thus provide more stability.
- the adjustable base may include one or more extendable ground supports. By extending these support(s), the bike or other exercise device has a longer and/or wider base to accommodate larger or taller riders to avoid the bike from tipping over.
- extra stability of the exercise device may be provided in different manners.
- the adjustable ground supports may extend from the front and/or from the rear of the bike or other exercise device.
- increased stability for larger or taller riders may be provided without significantly increasing the overall footprint so that the bike may still be used by larger or taller riders in limited space.
- the overall footprint may be longer to provide stability for tall riders, the overall increase is preferably small enough to avoid hitting nearby objects.
- the extendable ground supports may be easily adjusted without the use of specialized equipment.
- the adjustment may occur through pop-pins, quick release levers, retractable knobs or other suitable means. In this manner, an array of different riders, including taller and/or larger riders, may readily adjust and safely use the bike.
- the adjustable supports may be adjustable at a variety of different positions to accommodate different sized riders. This may occur through the use a quick release handle that may allow infinite adjustment that is not limited to specific locations dictated by, e.g., holes in the frame.
- the extendable support may be easily adjusted without the need for lubricants. This allows the adjustment without the user becoming dirty or causing slippery conditions.
- the extendable support(s) may be extended without bushings or other additional components. This avoids adding to manufacturing cost and/or creating maintenance issues.

- bike 1 may include frame 10 .
- frame 10 has an open geometry that allows the rider to adopt different riding positions, such as alternating sitting and standing positions, without hitting his or her knees and elbows. It is also preferred that frame 10 have sufficient rigidity and strength to allow the rider, including larger and/or taller riders, to vigorously ride bike 1 in a safe manner.
- Frame 10 may include base or ground support 220 , which may in turn include central ground support 230 , front ground support 250 and rear ground support 270 . As shown, central ground support 230 may join front and rear ground supports 250 , 270 to form a base that provides stability for bike 1 as it is ridden as discussed in more detail below.
- Ground support 220 may generally support the rest of frame 10 .
- down tube 13 and forks 15 may be connected to ground support 220 .
- Down tube 13 may support seat tube 14 , which may in turn support seat assembly 14 A which may include components to provide vertical and fore and aft adjustment of seat 14 B.
- Forks 15 may engage down tube 13 near the head of bike 1 .
- Upstanding post or head tube 16 may extend upward and support handlebars 30 .
- Handlebars 30 may be adjustable in the vertical and fore and aft directions.
- Pedal assembly 50 may be supported by down tube 13 or some other component of frame 10 .
- Pedal assembly 50 may include pedals 51 that may include toe clips and/or cleats.
- Pedal assembly 50 may also include a cog or chain wheel (not shown) and cranks 51 A connecting pedals 51 to the chain wheel.
- Flywheel 35 may be located between forks 15 and may be held in place by flanges 15 A extending from forks 15 or by some other component of frame 10 .
- a chain, belt or other suitable device may connect pedal assembly 50 and flywheel 35 to form a direct drive or fixed gear device.
- the chain, belt or other device connecting pedal assembly 50 and flywheel 35 may be protected by drive guard 26 . This helps protect the rider from moving parts.
- Bike 1 may also include resistance adjustor 40 which may adjust the force required for the rider to pedal. The resistance may be effected by brake pad 37 which is connected to frame 10 by rod 36 and which may rub on flywheel 35 with varying amounts of pressure depending on the amount of resistance selected by the rider. Bike 1 may also include other means to vary resistance such as magnetic resistance and other devices.
- Ground support 220 generally provides stability for bike 1 as it is ridden.
- Ground support 220 may include central ground support 230 that may run longitudinally or along the direction of the length of bike 1 .
- Central ground support 230 may extend from the bottom of down tube 13 to forks 15 .
- Support 230 may end at these frame elements or may extend beyond them.
- Central ground support 230 may join front and rear ground supports 250 , 270 .
- Each of front and rear grounds supports 250 , 270 may include lateral bars 252 , 272 extending perpendicular to central ground support 230 thereby providing lateral support and stability. It is preferred that front and rear lateral bars 252 , 272 have sufficient width to provide stability during a vigorous ride of bike 1 .
- Lateral bars 252 , 272 may include adjustable pads or feet 254 , 274 at or near their ends.
- Feet 254 , 274 are preferably adjustable in the vertical direction so that bike 1 may rest solidly on a floor or other surface. This vertical adjustment may occur by screwing or rotating the feet which may cause them to raise or lower along threads. However, other suitable adjustment means may be used.
- Front later bar 252 may also include transport wheels 256 that may allow bike 1 to be wheeled around to relocate it.
- FIG. 4A shows ground support 220 in a retracted position while FIG. 4B shows ground support in an extended position.
- the retracted position may be suitable when bike 1 is ridden by many riders such as small or average sized riders. That is, the footprint of ground support 220 may be sufficient to keep bike 1 stable when it is ridden by other than significantly heavy or tall riders.
- the length of central ground support 230 and the width of front and rear supports 350 , 270 provide enough longitudinal and lateral stability.
- the retracted position may also be used when bike 1 is not in use, or when it is being transported. To this end, it may be easier to tilt bike 1 (for wheels 256 engage the floor) when ground support 220 is in a retracted position.
- the retracted position also preferably renders the overall size of bike 1 small enough to fit within reasonably sized boxes and standard containers for shipping purposes. In this manner, an increased number of bikes 1 may be packed for shipping in a shipping container.
- rear ground support 270 has been extended to provide increased stability for large and/or tall riders.
- rear ground support 270 may include longitudinal bar 280 that is connected to lateral bar 272 and that also engages central ground support 230 .
- Longitudinal bar 280 may engage central ground support 230 and move relative thereto to allow adjustment.
- FIGS. 5A-C and 6 A-C are two series of top and bottom perspective views of rear support 270 in various positions relative to central ground support 230 .
- longitudinal member 280 and central ground support 230 may comprise C-shaped channels 282 , 232 .
- C-shaped channels 282 , 232 may be pointed downward, i.e., their open portion may face the ground.
- the C-shaped 282 channel of rear support member 270 may be dimensioned to fit within the C-shaped channel 232 of central ground support 230 and slide therein so that it may be extended and retracted.
- C-shaped channel 282 may be formed by top 282 A and sidewalls 282 B, 282 C.
- C-shaped channel 232 may be formed by top 232 A and sidewalls 232 B, 232 C.
- the outer dimensions of top and sides 282 A, 282 B, 282 C may be smaller than the corresponding tops and sides 232 A, 232 B, 232 C of central ground support.
- longitudinal support member 280 may easily move along central ground support 230 .
- it is preferred that the corresponding dimensions of C-channels 232 , 282 are not so different that longitudinal member 280 has significant play within central ground support 230 .
- C-channel 282 may be coated with a low frictional material as may the interior surface of C-channel 232 .
- Materials such as Teflon may be used.
- grease or other lubricants need not be applied between the engagement surfaces of C-channels 232 , 282 . This avoids the rider from becoming dirty or otherwise creating slippery exposed surfaces, e.g., when rear support member 270 is extended from central ground support 230 thereby exposing C-channel 282 .
- longitudinal member 280 may include one or more retractable knobs 284 that may engage holes 234 in central ground support 230 .
- Support 230 may have a number of holes 234 to accommodate knobs 284 at different positions as shown in FIGS. 5A-B and 6 A-B.
- knob(s) 284 In order to move rear ground support relative to central ground support, the rider may depress knob(s) 284 and either move rear support 270 to the front or rear until knob(s) 284 are positioned to engage other hole(s) 234 .
- knob(s) 284 When rear support 270 has been moved a sufficient distance relative to support 230 , knob(s) 284 may engage a new hole or holes to secure rear ground support 270 in an adjusted position relative to central ground support 230 .
- knobs 284 may be spring loaded such that they extend laterally upon encountering a hole 234 .
- sidewalls 232 B, 232 C may include inwardly extending lips 232 BB, 232 CC that prevent longitudinal member 280 from disengaging central ground support 230 . But even without lips 232 BB, 232 CC, the weight of bike 1 may preferably keep longitudinal member 280 and central ground support 230 aligned.
- rear ground support 270 may engage central ground support 230 .
- pop-pins may be installed on central ground support 230 , wherein the pin may extend inward to engage holes (not shown) in longitudinal member 280 (where, for example, knobs 284 were located in the above-described embodiment).
- central ground support may include a quick release mechanism that includes a pin extending inward from support 230 to engage either of sidewalls 282 B, 282 C by a friction fit.
- front ground support 250 may comprise a longitudinal member that may be similar to rear longitudinal member 280 and that may slide within the front portion of central ground support 230 . In this manner, increased stability may be provided from the front end of bike 1 .
- FIG. 7 an alternate embodiment is now described.
- the reference numerals in FIG. 7 are similar to those used for the components in earlier figures but with a leading “1” thereby making the reference numerals in the 1000s.
- a primary feature of the embodiment of FIG. 7 is that the components of the adjustable ground support 1220 are configured as tube-in-tube as opposed to C-channels.
- the cross-section of the tubular members may vary, but the scope of the invention includes square, rectangular, other polygonal and circular cross-sections. This configuration preferably provides increased stability and facilitates adjustment.
- central ground support 1230 may comprise an enclosed tube that forms a receptacle 1232 for rear ground support 1270 , and more particularly for longitudinal bar 1280 .
- Longitudinal bar 1280 may also comprise a closed tube cross-section that is sized to fit within central ground support 1230 .
- Longitudinal bar 1280 may comprise top surface 1282 A, along with sidewalls 1282 B, 1282 C, as well as a bottom wall to complete the tubular structure. In this configuration, bar 1280 may be adjusted with respect to support 1230 to provide the stability described above.
- the manner in which longitudinal bar 1280 may slide within central ground support 1230 may be similar to the manner in which the seat and handlebars may slide within their respective frame members to effect adjustment.
- Central ground support 1230 may also include sleeve 1230 A that may comprise plastic or other suitable material.
- Sleeve 1230 A may serve as a material between ground support 1230 and rear ground support 1270 (and more particularly longitudinal bar 1280 ) which facilitates adjustment. To this end, sleeve 1230 A may provide a less frictional surface on which to move bar 1280 relative to support 1230 than would exist between two metal surfaces.
- central ground support 1230 may include a tubular receptacle at its front end to receive a front ground support that may be slid in and out of central ground support 1230 .
- a sleeve may also be used to facilitate adjustment.

Description
- This application claims the benefit of U.S. Provisional Application No. 62/142,363, filed Apr. 2, 2015, the contents of which are incorporated herein by reference.
- The present invention generally relates to exercise equipment such as exercise bikes, including an exercise bike having an adjustable ground support so that the bike may be safely ridden by larger and/or taller riders.
- Exercise bikes have become increasingly popular in recent years. This has included exercise bikes that may be used either at home or in a gym setting.
- Exercise bikes that simulate outdoor riding are a particularly effective way for users to obtain a total body workout and provide an enjoyable ride that retains the rider's interest. Such bikes allow the rider to place his or her hands on different areas of the handlebar and also allow the rider to adopt different riding positions, such as sitting and standing. This allows the rider to simulate the experience of riding on hills, riding across flat terrain and other riding conditions. Such bikes have generally become known as indoor cycles. Because they are ridden in different positions, such bikes need to have a strong and stable frame and also need to provide stability to the rider.
- Because exercise bikes are often ridden by different people of different sizes, indoor cycles and other exercise devices typically provide some amount of adjustability to accommodate different riders. In a gym setting, it is desirable that the bike be easily adjusted by multiple users, so that one bike taking up a certain amount of space on the floor may be ridden by differently sized riders. Similarly, in the home setting, it is desirable that the bike easily accommodate different family members of different sizes. This is necessary especially when considering the limited space that may be available in the gym or at home. This also avoids the situation of having differently sized versions of the same bike or other exercise device.
- Existing indoor cycles and other exercise bikes have provided different types of adjustment for some time to accommodate the foregoing needs. For example, it is common for a rider to adjust seat height and handlebar height. A rider may also adjust the fore and aft position of the seat and handlebar.
- However, the adjustments currently available may not provide stability for especially large or tall riders. This is an issue because if an exercise bike is adjusted for maximum seat and handlebar height to accommodate a very tall rider, the bike may become top heavy and unsafe. This is especially so where the bike is ridden in a standing position or in another vigorous fashion. To this end, the height and/or weight of particularly tall or heavy riders may cause existing exercise bikes to tip to one side or another during vigorous exercise. Accordingly, there is a need for an exercise bike that may be adjusted to safely accommodate especially large or tall riders.
- Beyond the space taken up by a bike at the gym or at home, another consideration is the box or other container in which it will be shipped after manufacture. While certain exercise devices may allow some adjustability, this may require a large box or container which may increase shipping costs. Accordingly, there is a need for an exercise bike with increased adjustability but which may still be shipped in a standard or reasonably sized box or container.
- Existing devices may allow for some adjustability in order to account for differently sized riders or users. However, these devices have various shortcomings and/or do not allow an indoor cycle ride that simulates outdoor riding conditions, including riding in sitting and standing positions.
- For example, U.S. Pat. No. 8,409,060 to Hsu entitled “Exercise Bike for Rehabilitation” discloses a device for rehabilitation. The device includes a movable base that allows the user to adjust the distance between the seat and the handlebars of the device. While the adjustable base may accommodate users of different heights, it does not address the need for providing extra stability that may be necessary for taller or larger riders. Furthermore, this device is not at all intended to allow the rider to ride in different positions to simulate outdoor bike riding conditions in which vigorous riding could cause the device to tip in the first place.
- Similarly, U.S. Pat. No. 5,971,894 to Chen, entitled “Stationary Exercising Bicycle” discloses an exercise device with a movable base. The purpose of the movable base in this device appears to be to raise or lower the seat for users of different heights. However, it does not appear that movement of the base is intended for increased support for larger or taller riders. In addition, the device looks inherently unstable and top heavy, and has many rotating joints that would appear prone to failure. Furthermore, this device does not does not allow riding in different positions and does not appear to address instability that could be caused by vigorous riding of a tall or heavy person.
- Likewise, U.S. Patent Application Publication 2012/0295770 A1 to Lo discloses an exercise device with a movable base. But in this device, the base is movable to accommodate sitting and lying positions. The base is not designed to provide structural support for larger users. In addition, the device is not designed to simulate an outdoor bicycle ride where the rider may stand up and sit down or address associated instability.
- Some existing devices have adjustable support bars that may provide additional structural support, such as U.S. Pat. No. 5,439,433A to Lunden. However, this device is a step climber and is not at all an exercise bike that may allow the rider to simulate outdoor bike riding conditions. Furthermore, the adjustable support bar appears limited to the situation where the step climber wants to shift his or her weight to the rear of the steps on which the user stands. It provides no lateral stability or protection against tipping from side to side.
- In view of the foregoing, there is a need for a versatile and adjustable exercise bike that has an adjustable support that may accommodate larger and taller riders so that they may safely ride the bike. There is also a need for this bike to provide a ride for a heavy or tall rider that simulates outdoor bike riding conditions, such as riding in alternating sitting and standing positions. There is also a need that the adjustment mechanism may be easily and cleanly adjusted by the rider.
- The current invention addresses the foregoing issues and provides an improvement over existing devices.
- In a first aspect of the invention, the exercise bike is configured to accommodate a variety of different sized riders, including riders who may be heavy, large and/or tall. To this end, the bike includes a frame that may adjust to provide more stability so that larger and taller riders may safely ride the bike. For example, the frame may include an adjustable base that may be extended to provide a larger footprint on the ground and thus provide more stability. The adjustable base may include one or more extendable ground supports. By extending these support(s), the bike or other exercise device has a longer and/or wider base to accommodate larger or taller riders to avoid the bike from tipping over.
- In another aspect of the invention, extra stability of the exercise device may be provided in different manners. For example, the adjustable ground supports may extend from the front and/or from the rear of the bike or other exercise device.
- In another aspect of the invention, increased stability for larger or taller riders may be provided without significantly increasing the overall footprint so that the bike may still be used by larger or taller riders in limited space. For example, while the overall footprint may be longer to provide stability for tall riders, the overall increase is preferably small enough to avoid hitting nearby objects.
- In another aspect of the invention, the extendable ground supports may be easily adjusted without the use of specialized equipment. For example, it is preferred that the adjustment may occur through pop-pins, quick release levers, retractable knobs or other suitable means. In this manner, an array of different riders, including taller and/or larger riders, may readily adjust and safely use the bike.
- In another aspect of the invention, the adjustable supports may be adjustable at a variety of different positions to accommodate different sized riders. This may occur through the use a quick release handle that may allow infinite adjustment that is not limited to specific locations dictated by, e.g., holes in the frame.
- In another aspect of the invention, the extendable support may be easily adjusted without the need for lubricants. This allows the adjustment without the user becoming dirty or causing slippery conditions.
- In another aspect of the invention, the extendable support(s) may be extended without bushings or other additional components. This avoids adding to manufacturing cost and/or creating maintenance issues.
- Other aspects of the invention may involve any of the foregoing in combination with each other.

FIG. 7 is a perspective view showing an alternate embodiment with a tubular construction and sleeve. - Preferred embodiments of
bike 1 of the current invention are now described with reference to the figures. The same or similar components may bear the same reference numerals in different figures. - As shown in the figures,
bike 1 may includeframe 10. In a preferred embodiment,frame 10 has an open geometry that allows the rider to adopt different riding positions, such as alternating sitting and standing positions, without hitting his or her knees and elbows. It is also preferred thatframe 10 have sufficient rigidity and strength to allow the rider, including larger and/or taller riders, to vigorously ridebike 1 in a safe manner. -
Frame 10 may include base orground support 220, which may in turn includecentral ground support 230,front ground support 250 andrear ground support 270. As shown,central ground support 230 may join front and rear ground supports 250, 270 to form a base that provides stability forbike 1 as it is ridden as discussed in more detail below. -
Ground support 220 may generally support the rest offrame 10. To this end,down tube 13 andforks 15 may be connected toground support 220. Downtube 13 may support seat tube 14, which may in turn supportseat assembly 14A which may include components to provide vertical and fore and aft adjustment ofseat 14B. -
Forks 15 may engage downtube 13 near the head ofbike 1. Upstanding post orhead tube 16 may extend upward and support handlebars 30.Handlebars 30 may be adjustable in the vertical and fore and aft directions. -
Pedal assembly 50 may be supported bydown tube 13 or some other component offrame 10.Pedal assembly 50 may includepedals 51 that may include toe clips and/or cleats.Pedal assembly 50 may also include a cog or chain wheel (not shown) and cranks51 A connecting pedals 51 to the chain wheel.Flywheel 35 may be located betweenforks 15 and may be held in place byflanges 15A extending fromforks 15 or by some other component offrame 10. A chain, belt or other suitable device may connectpedal assembly 50 andflywheel 35 to form a direct drive or fixed gear device. The chain, belt or other device connectingpedal assembly 50 andflywheel 35 may be protected by drive guard 26. This helps protect the rider from moving parts. -
Bike 1 may also includeresistance adjustor 40 which may adjust the force required for the rider to pedal. The resistance may be effected bybrake pad 37 which is connected to frame 10 byrod 36 and which may rub onflywheel 35 with varying amounts of pressure depending on the amount of resistance selected by the rider.Bike 1 may also include other means to vary resistance such as magnetic resistance and other devices. - It should be noted that different configurations of frames are within the scope of the invention, and the foregoing is only one example. To this end, the frames and other disclosure of U.S. Pat. Nos. D709,567 and D677,747 are incorporated by reference as if fully set forth herein.

Adjustable ground support 220 is now further described with reference toFIGS. 2, 3, 4A and 4B . As noted above,ground support 220 generally provides stability forbike 1 as it is ridden.Ground support 220 may includecentral ground support 230 that may run longitudinally or along the direction of the length ofbike 1.Central ground support 230 may extend from the bottom ofdown tube 13 toforks 15.Support 230 may end at these frame elements or may extend beyond them.Central ground support 230 may join front and rear ground supports 250, 270. - Each of front and rear grounds supports 250, 270 may include
lateral bars central ground support 230 thereby providing lateral support and stability. It is preferred that front and rear lateral bars 252, 272 have sufficient width to provide stability during a vigorous ride ofbike 1. -
Lateral bars feet Feet bike 1 may rest solidly on a floor or other surface. This vertical adjustment may occur by screwing or rotating the feet which may cause them to raise or lower along threads. However, other suitable adjustment means may be used. Front later bar 252 may also includetransport wheels 256 that may allowbike 1 to be wheeled around to relocate it. - An embodiment showing how
ground support 220 may be adjusted is now further described with reference toFIGS. 4A and 4B . Generally,FIG. 4A showsground support 220 in a retracted position whileFIG. 4B shows ground support in an extended position. The retracted position may be suitable whenbike 1 is ridden by many riders such as small or average sized riders. That is, the footprint ofground support 220 may be sufficient to keepbike 1 stable when it is ridden by other than significantly heavy or tall riders. In this situation, the length ofcentral ground support 230 and the width of front andrear supports 350, 270 provide enough longitudinal and lateral stability. - The retracted position may also be used when
bike 1 is not in use, or when it is being transported. To this end, it may be easier to tilt bike 1 (forwheels 256 engage the floor) whenground support 220 is in a retracted position. The retracted position also preferably renders the overall size ofbike 1 small enough to fit within reasonably sized boxes and standard containers for shipping purposes. In this manner, an increased number ofbikes 1 may be packed for shipping in a shipping container. - In
FIG. 4B ,rear ground support 270 has been extended to provide increased stability for large and/or tall riders. As shown,rear ground support 270 may includelongitudinal bar 280 that is connected tolateral bar 272 and that also engagescentral ground support 230.Longitudinal bar 280 may engagecentral ground support 230 and move relative thereto to allow adjustment. - The engagement between
central ground support 230 andrear ground support 270 is best shown inFIGS. 5A-C and 6A-C which are two series of top and bottom perspective views ofrear support 270 in various positions relative tocentral ground support 230. As shown,longitudinal member 280 andcentral ground support 230 may comprise C-shapedchannels channels rear support member 270 may be dimensioned to fit within the C-shapedchannel 232 ofcentral ground support 230 and slide therein so that it may be extended and retracted. - More specifically, C-shaped
channel 282 may be formed by top 282A andsidewalls channel 232 may be formed by top 232A andsidewalls rear support member 270 sliding alongcentral ground support 230, the outer dimensions of top andsides sides longitudinal support member 280 may easily move alongcentral ground support 230. However, it is preferred that the corresponding dimensions of C-channels longitudinal member 280 has significant play withincentral ground support 230. - To facilitate the movement of
member 280 relative tomember 230, the exterior surface of C-channel 282 may be coated with a low frictional material as may the interior surface of C-channel 232. Materials such as Teflon may be used. In this manner, it is preferred that grease or other lubricants need not be applied between the engagement surfaces of C-channels rear support member 270 is extended fromcentral ground support 230 thereby exposing C-channel 282. - The manner in which rear ground support may be adjusted relative to
central ground support 230 is now further described. In one embodiment, as shown inFIGS. 5A-C and 6A-C,longitudinal member 280 may include one or moreretractable knobs 284 that may engageholes 234 incentral ground support 230.Support 230 may have a number ofholes 234 to accommodateknobs 284 at different positions as shown inFIGS. 5A-B and 6A-B. - In order to move rear ground support relative to central ground support, the rider may depress knob(s) 284 and either move
rear support 270 to the front or rear until knob(s) 284 are positioned to engage other hole(s) 234. Whenrear support 270 has been moved a sufficient distance relative to support 230, knob(s) 284 may engage a new hole or holes to securerear ground support 270 in an adjusted position relative tocentral ground support 230. To this end, knobs 284 may be spring loaded such that they extend laterally upon encountering ahole 234. - In order to keep
longitudinal member 280 withincentral ground support 230, sidewalls 232B, 232C may include inwardly extending lips 232BB, 232CC that preventlongitudinal member 280 from disengagingcentral ground support 230. But even without lips 232BB, 232CC, the weight ofbike 1 may preferably keeplongitudinal member 280 andcentral ground support 230 aligned. - There are other manners in which
rear ground support 270 may engagecentral ground support 230. For example, pop-pins may be installed oncentral ground support 230, wherein the pin may extend inward to engage holes (not shown) in longitudinal member 280 (where, for example, knobs 284 were located in the above-described embodiment). - As another alternative, central ground support may include a quick release mechanism that includes a pin extending inward from
support 230 to engage either of sidewalls 282B, 282C by a friction fit. An advantage of this embodiment is that the adjustment is infinite in that it is not limited to the locations of holes in eithercentral ground support 230 and/orrear support member 270. - In an alternative embodiment,
front ground support 250 may comprise a longitudinal member that may be similar to rearlongitudinal member 280 and that may slide within the front portion ofcentral ground support 230. In this manner, increased stability may be provided from the front end ofbike 1. - Referring to
FIG. 7 , an alternate embodiment is now described. The reference numerals inFIG. 7 are similar to those used for the components in earlier figures but with a leading “1” thereby making the reference numerals in the 1000s. A primary feature of the embodiment ofFIG. 7 is that the components of the adjustable ground support 1220 are configured as tube-in-tube as opposed to C-channels. The cross-section of the tubular members may vary, but the scope of the invention includes square, rectangular, other polygonal and circular cross-sections. This configuration preferably provides increased stability and facilitates adjustment. - As shown in
FIG. 7 ,central ground support 1230 may comprise an enclosed tube that forms areceptacle 1232 forrear ground support 1270, and more particularly forlongitudinal bar 1280.Longitudinal bar 1280 may also comprise a closed tube cross-section that is sized to fit withincentral ground support 1230.Longitudinal bar 1280 may comprisetop surface 1282A, along with sidewalls 1282B, 1282C, as well as a bottom wall to complete the tubular structure. In this configuration,bar 1280 may be adjusted with respect to support 1230 to provide the stability described above. The manner in whichlongitudinal bar 1280 may slide withincentral ground support 1230 may be similar to the manner in which the seat and handlebars may slide within their respective frame members to effect adjustment. -
Central ground support 1230 may also includesleeve 1230A that may comprise plastic or other suitable material.Sleeve 1230A may serve as a material betweenground support 1230 and rear ground support 1270 (and more particularly longitudinal bar 1280) which facilitates adjustment. To this end,sleeve 1230A may provide a less frictional surface on which to movebar 1280 relative to support 1230 than would exist between two metal surfaces. - As with the earlier embodiments, the adjustability provided by the embodiment in
FIG. 7 may also be accomplished with an adjustment in the front of the bike or other exercise device. That is,central ground support 1230 may include a tubular receptacle at its front end to receive a front ground support that may be slid in and out ofcentral ground support 1230. In this embodiment, a sleeve may also be used to facilitate adjustment. - Although certain presently preferred embodiments of the invention have been described herein, it will be apparent to those skilled in the art to which the invention pertains that variations and modifications of the described embodiments may be made without departing from the spirit and scope of the invention.
