Description

    RELATED APPLICATIONS
  • This application is a continuation of U.S. patent application Ser. No. 10/759,539, filed Jan. 19, 2004, which claims the priority benefit of U.S. Provisional Application No. 60/441,330, filed on Jan. 17, 2003, which is hereby incorporated by reference in its entirety.
  • BACKGROUND OF THE INVENTION
  • 1. Field of the Invention
  • The present invention generally relates to exercise bicycles. More specifically, the present invention relates to exercise bicycles having improved step through regions and/or moveable reading supports.
  • 2. Description of the Related Art
  • The exercise industry manufactures a variety of machines that provide users with cardiovascular exercise. These machines include stepper machines, elliptical machines, spinner bicycles and recumbent bicycles. The design of each of these types of machines results in certain advantages and disadvantages.
  • Users weigh many factors in determining which exercise equipment to use during time spent in a gym or when exercising at home. Among the factors weighed is ease of use. Accordingly, exercise equipment designers have continually sought to improve the ease of use of the various machines.
  • SUMMARY OF THE INVENTION
  • One area in which current exercise bicycle designs need improvement is entry and exit access. Current bicycle designs generally feature an enclosed elevated region between the seat and the handlebars. This enclosed region generally houses drive train components that are used to adjust the level of pedaling difficulty. This enclosed region, however, requires a user to raise a leg over the enclosed region when mounting and dismounting the bicycle. Some designs have provided a slight separation between the handlebars and the seat, which separation provides some degree of clearance. These designs, however, generally taper in a downward direction such that the narrowest region is at the bottom. This is disadvantageous in that users may not be able to easily mount and dismount the equipment. For instance, because people have different foot sizes, some people will have to lift their foot higher than others in order to mount or dismount the bicycle.
  • Current designs also are fairly heavy and difficult to move. In some gyms, users like to talk while exercising. In such instances, the equipment may not be positioned relative to other equipment in a manner that allows easy conversation. Thus, equipment that is made for easier movement during relocation while still maintaining an adequately fixed positioned during exercise is desired. Such equipment also can facilitate cleaning the floor around the equipment.
  • Often, people using exercise machines also read while exercising. Reading on some equipment, however, is fairly difficult. For instance, the reading material must be held during the exercise, which can be fairly difficult for extended periods of time. In addition, if a reading support is provided, the support may not be properly positioned for each user. Accordingly, an adjustable reading support is desired.
  • In accordance with one embodiment of the present invention, an exercise machine comprises a frame. The frame comprises a base. A seat is mounted to a rear portion of the frame and a display is mounted to a forward portion of the frame. A resistance force generating assembly is disposed generally below a portion of the display. The assembly is disposed within a first housing. A second housing is formed separate of the first housing and is disposed generally rearward of the first housing. An opening being defined between the first and the second housings and the opening being wider at a location proximate the base than at an elevation higher than the location.
  • In accordance with another embodiment of the present invention, an exercise machine comprises a frame with a seat supported by a rear portion of the frame. A forward portion of the frame supports a hand grip and the forward portion of the frame movably supports a reading support. The reading support is disposed forward of the seat and is adjustable relative to the seat.

  • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
  • With reference now to FIGS. 1-6, a recumbent bicycle 10 is illustrated therein. While various features, aspects and advantages of embodiments of the present invention will be described in the context of the illustrated bicycle, certain features, aspects and advantages can be used with other types of exercise equipment. Accordingly, while illustrating the below-described features, aspects and advantages in the context of a bicycle-type of exercise apparatus, it is not intended that the scope of the present invention necessarily be limited to such exercise apparatuses unless expressly recited by the claims.
  • With reference now to FIGS. 1, 7 and 8, the illustrated bicycle 10 advantageously comprises a simplified frame assembly 12. The illustrated frame assembly 12 comprises a base 14 that curves upward at a forward end of the frame assembly 12 such that it forms a standard 16. The base 14 in the illustrated arrangement is formed of a rectangular aluminum tube. Other shapes and materials also can be used, as desired. A pair of legs 15 extends laterally outward at both a forward end and a rearward end of the base 14. Advantageously, a leveling foot 17 can be disposed along a bottom portion of each leg 15. The leveling foot 17 can be raised or lowered by rotation such that the frame assembly 12 can be mounted in a level orientation irrespective of the levelness of the floor.
  • In the illustrated arrangement, the base 14 and the standard 16 are separately formed and secured together in a suitable manner, including but not limited to, welding, physical interlocking connections, mechanical fasteners and the like. In some embodiments, the base 14 and the standard 16 can be integrally formed. While the illustrated arrangement may reduce tooling costs, the integrated arrangement could reduce overall manufacturing costs during mass production.
  • A pair of longitudinally spaced seat standards 20 extend upward from a rear portion of the base 14. As used herein, the longitudinal direction is the direction in which a user faces during operation of the bicycle 10 (e.g., front to rear). In the illustrated arrangement, a pair of stays 22 extends longitudinally between the two seat standards 20 to reinforce the seat standards 20. Specifically, in the illustrated arrangement, the stays 22 slope upward from the rearward standard 20 to the forward standard 20. Other seat supporting and elevating constructions can be used if desired.
  • A seat 24 is positioned above and supported by the seat standards 20 in the illustrated arrangement. The seat 24 preferably is positioned over a slide plate 26 that is mounted to the seat standards 20. The slide plate 26 can be mounted at an angle a to horizontal H (see FIGS. 4 and 7). By mounting the slide plate 26 at an angle, the seat can be adjusted both toward the pedals and up and down in a manner that allows proper ergonomics to be achieved.
  • The seat 24 preferably engages the slide plate 26 in a manner that secures the seat from being lifted from the slide plate 26. In one embodiment, the seat 24 can be mounted on rollers 27 that roll within a channel formed in the slide plate 26 or the slide plate can contain rollers over which a rail connected to a portion of the seat 24 rolls. Other manners of allowing the seat to translate also can be used.
  • The slide plate 26 comprises inwardly extending channels that are positioned on the lateral sides of the plate 26. A framework 28 is supported by rollers 27 that are positioned within the channels such that the framework 28 can be formed fore and aft along the slide plate 26. This arrangement allows the slide to be adjusted forward and rearward in any suitable manner.
  • In one arrangement, a seat lock 29 has a handle 31 that is positioned proximate a forward portion of the seat 24, which handle 31 unlocks the seat 24 for movement when the handle 31 is manipulated and locks the seat 24 against movement when the handle 31 is released. In some embodiments, the seat locking arrangement is similar to those used in the automotive industry for adjustably fixing the location of manually adjustable seats. For instance, as illustrated, a wrap-around handle can be used which allows adjustment of the seat by lifting the handle from two or more one contiguous sides.
  • The seat 24 in the illustrated arrangement comprises a pair of cushions that are connected to the framework 28: a bottom cushion 30 and a back cushion 32. In some arrangements, a single cushion can be used to provide both vertical and longitudinal support.
  • Two arm rests 34 (see FIG. 2) also are connected to the framework 28. The arm rests 34 allow a user to better hold a magazine, book, newspaper or the like while riding the bicycle. In one arrangement, the arm rests 34 are connected to a single arm rest support 36, which is generally U-shaped. The support 36 extends to both lateral sides of the bottom cushion 30. In the embodiment of FIG. 4, the support 36 extends laterally and generally longitudinally and, in the embodiment of FIG. 7, the support 36 extends laterally and generally vertically. In other arrangements, the arm rests 34 can be pivotally connected to the framework 28 or other portion of the seat 34 or bicycle 10 such that the arm rests 34 can be pivoted upward and rearward or outward and rearward relative to the seat 24 to facilitate entry to and exit from the seat 24.
  • An upper portion of the standard 16 supports a display 40. The display can have any suitable construction. Preferably, the display 40 comprises an electronic readout or other suitable configuration to allow the user to receive information regarding the rate of speed, calories burned and the like. In addition, the display preferably allows the input of information by the user. Heart rate sensors 41 and the like also can be mounted proximate the display 40. The electronics relating to the display 40 and the sensors 41 can be connected to a power source with cables that extend through the standard 16. Such displays are well known to those of ordinary skill in the art.
  • Proximate the display 40, the bicycle 10 also can feature a reading support 42, which is either integrated or separately formed relative to the display 40. In the arrangements illustrated in FIG. 4 and FIG. 8, the reading supports 42 are formed separate of the display 40. Advantageously, the reading support 42 can be designed for articulation relative to the frame assembly 12. In some arrangements, the reading support 42 is designed to move toward or away from the display 40. In other arrangements, the reading support 42 is designed to move with the display 40 relative to the frame assembly 12 and the user. In one arrangement, a four bar linkage is used to allow the reading support 42 to be positioned as desired by the user (e.g., change the height, angle and/or distance to the user).
  • With reference to FIGS. 8-10, in one arrangement, the bicycle 10 comprises a strut 50 that is suitably supported by the frame assembly. The illustrated strut 50 is secured with fasteners to the standard 14. Other mounting techniques also can be used (e.g., welding, mechanically interlocking constructions, etc.). In the illustrated embodiment, the strut 50 is a sleeve. The illustrated strut 50 comprises a number of holes 52. The reading support 42 also comprises an elongated support member 54. The support member 54 of the reading support 42 is designed to slide within the strut 50 of the frame assembly 12 in a telescoping manner. In some arrangements, the strut 50 may be designed slide within the support member 54 rather than the support member 54 being designed to slide with the strut 50. Other functional relationships that allow the reading support 42 to be carried by the frame assembly 12 in a suitably adjustable manner also can be used.
  • The reading support 42 of the arrangement illustrated in FIGS. 1-4 comprises a channel 60 and a handgrip assembly 62. The channel 60 advantageously has been designed to accommodate various reading media. While the illustrated channel is fairly short in height, it should be appreciated that an extension member could extend upward to provide added support for reading media. In one arrangement, such an extension member can be manufactured of a clear lexan or Plexiglas material in order to allow a user to see the display 40 through the extension member.
  • The handgrip assembly 62 advantageously comprises heart rate sensors. While the handgrip assembly 62 moves with the channel 60 in the illustrated arrangement, the channel 60 may be designed to move separate of the handgrip assembly 62 if desired.
  • With reference initially to FIG. 9, a plunger assembly 64 is provided to adjust the relative positions of the support members 50, 54. As shown, a plunger knob 66 (FIG. 1) or button 67 (FIG. 9) is connected by a rod 68 to a rocker arm 70 that is disposed at the end opposite of the support member 54 relative to the plunger knob 66 or button 67. The rod 68 can be connected to the plunger knob 66 or button 67 in any suitable manner (e.g., threaded connection, mechanically interlocking connection, etc.). The rocker arm 70 pivots when the plunger knob 66 or button 67 is moved in an axial direction. The pivoting of the rocker arm 70 allows a locking finger 72 to retract and extend, depending upon the rotational orientation of the rocker arm about an axis defined by a pin 73.
  • In the embodiments of FIGS. 1 and 9, the plunger assembly is spring biased such that the locking pin 72 is extended when the plunger knob 66 is not being manipulated. To facilitate movement, the plunger knob 66 can be depressed to move the reading support 42 toward the display 40 and the plunger knob 66 can be pulled to move the reading support 42 away from the display 40. In the embodiment of FIG. 9, the button 67 is adapted to be pressed for movement and preferably is not designed for pulling movement as compared to the knob 66 of FIG. 1. Nevertheless, movement of the plunger knob 66 or the button 67 can be used to enable movement of the reading support 42 in either direction relative to the display 40 when such movement of the support 42 is desired.
  • With reference still to FIGS. 9-11, a second embodiment of the reading support 42 comprises a gripping structure 74. The gripping structure 74 enables the reading support 42 to physically secure reading media in position rather than simply supporting the reading media. In the illustrated arrangement, a front arm 76 and a rear arm 78 are biased with a biasing member 79 (e.g., a spring, etc.) to a closed position. In other arrangements, the front arm and/or the rear arm 78 can be made of a suitable material to allow sufficient deformation without yielding to allow the two members to simply secure the reading media between the two arms 76, 78. Using an arrangement such as that illustrated, which features the biasing member, however, facilitates the support and securement of a wider range of reading media sizes and shapes.
  • With reference again to FIG. 1, the illustrated bicycle 10 advantageously comprises a resistance region 80 that is separated from the seat 24. A resistance force generating assembly 82 (see FIG. 7) is contained within the resistance region 80. Any suitable resistance force generating assembly 82 can be used. For instance, belts, friction brakes and the like can be used. Preferably, however, a flywheel and generator combination 84 is used. As illustrated, two pedals 86 are connected via crank arms 88 to a circular crank 90. The crank 90 is connected with a tensioned belt drive 92 to the flywheel and generator combination 84. Advantageously, the combination 84 is mounted within a corner defined by the standard 16 and the base 14. Additionally, a bracing member 94 extends between the base 14 and the standard 16. The bracing member 94 defines a mounting location for the crank 90 and a circuit board 91.
  • With reference again to FIG. 1, the resistance region 80 preferably is housed within a resistance housing 100. Because of the compact arrangement of the resistance force generating assembly 82, the resistance housing 100 can for formed as a separate component from the other housings used on the bicycle. For instance, the resistance housing 100 can be formed separate of a seat housing 102 that is used to shroud the structure supporting the seat 24. Thus, as shown in FIG. 1, a valley 104 is defined between the resistance housing 100 and the seat housing 102. The valley 104 provides a step through design for the bicycle 10. The valley can have any suitable configuration. Advantageously, the illustrated valley 104 comprises a wider opening proximate the base than the width of the valley 104 at a vertically higher location. The wider opening proximate the base provides enhanced clearance at a level through which a user's foot will pass while mounting and dismounting the bicycle 10. While the illustrated valley 104 provides the advantage of growing wider as it goes downward, other configurations also can grow wider while descending and, as such, the illustrated design provides an aesthetically unique and pleasing appearance.
  • The pedals 86 each preferably comprises a foot strap arrangement 110. Any suitable foot strap arrangement can be used (e.g., hook and loop style such as Velcro, buckles, clips, etc.). With reference to FIG. 13, the foot strap arrangement 110 comprises a flexible strap 112. The illustrated strap 112 comprises a ribbed portion 114 at one end and an aperture 116 at the other end. A wider portion 118 is interposed between the aperture 116 and the ribbed portion 114.
  • The ribbed portion 114 is sized and configured to pass through a gripping member 120. The gripping member 120 comprises a mounting member 122 and a clasp 124. The clasp 124 can be secured to the mounting member 122 in any suitable manner (e.g., mechanically interlocking constructions, threaded fasteners, etc.) and, in the illustrated arrangement, the clasp 124 is secured to the mounting member 122 with a rivet 126. In some embodiments, the clasp 124 can be formed integrally with the mounting member 122.
  • The clasp 124 has a construction that allows the ribbed portion 114 to be inserted into the clasp 124. The clasp 124 then can be manipulated to allow selective movement of the ribbed portion 114 within the clasp 124. The selective movement allows the length of the strap to be adjusted such that users having various feet sizes can be accommodated. In the illustrated arrangement, a physical stop is incorporated into the strap 112 to reduce the likelihood that the strap 112 will be completely removed from the clasp. In the illustrated arrangement, the stop comprises a rivet 128. Other suitable stop configurations can be used if desired; however, the rivet 128 provides a simple and effective manner of creating a physical stop.
  • The illustrated pedal 86 comprises a pair of ears 130. The ears 130 allow the strap 112 to be releasably connected to the pedal 86. One ear is sized and configured to extend through an aperture formed in the mounting member 122 and the other ear is size and configured to extend through the aperture 116 in the strap 112. In other embodiments, either the mounting member 122 or the other end of the strap 112 can be permanently or semi-permanently attached to the pedal 86. The illustrated arrangement, however, advantageously allows for easy removal and replacement of the strap if needed or desired. In addition, the arrangement allows removal of the strap 112 for length adjustments if desired.
  • The feet 17 preferably support the illustrated frame assembly 12. The feet 17 allow the frame assembly 12 to be leveled and to sit slightly above the floor surface on which the frame assembly 12 is supported. In one arrangement, fixed wheels 132 can be provided at one end, preferably the front. Accordingly, the rear of the bicycle 10 can be raised upward which places the wheels 132 in engagement with the ground such that the bicycle 10 can be easily relocated.
  • With reference to FIGS. 14 and 15, a selectively deployable roller or retractable caster assembly 140 can be attached to the exercise device 10′, 10″ (like components between an earlier embodiment and the embodiments of FIGS. 14 and 15 have been given like reference numerals with the addition of a single prime ′ in the embodiment of FIG. 14 and a double prime ″ in the embodiment of FIG. 15). The selectively deployable caster assembly 140 can be connected to a rear portion of the exercise device 10′, 10″ in any suitable manner. Advantageously, the assembly 140 comprises a member that can be lowered into a position that raises the rear of the exercise device 10′, 10″. With the member of the assembly 140 lowered, the wheels 132″ at the other end of the bicycle preferably are brought into contact with the ground due to the angle of inclination and the location of the wheels 132″ forward of the front end of the frame assembly 12″. Thus, by lowering the member of the assembly 140, the bicycle can be supported on rollers to further ease movement of the bicycle, when desired.
  • In the illustrated arrangement, the retractable caster assembly 140 preferably comprises a step pad 142 that is mounted on a lever 144. The lever 144 can be connected to a post 146 that can be connected to the wheel 148. As the lever 144 is pivoted downward, the post 146 is moved downward within an outer sleeve 150 such that the wheel 148 is driven into the ground or other supporting surface. As the wheel 148 is driven downward, the rear portion of the exercise device is lifted upward. The exercise device then is able to be easily moved about the facility. Any other suitable selectively deployable caster assembly also can be used. See, for example, U.S. Pat. No. 4,249,282, which is incorporated herein in its entirety. In one arrangement, the retractable caster can be locked from movement such that a key or other access-limiting device is required for operation of the caster.
  • The retractable caster assembly 140 can be mounted either to a portion of the frame assembly 12 or to a portion of the housing such as the seat housing 102. In one preferred arrangement, the assembly 140 is substantially contained within enclosure such that the assembly 140 generally does not adversely affect the pleasing aesthetic appearance of the exercise equipment.
  • Although the present invention has been described in terms of a certain preferred embodiments, other embodiments apparent to those of ordinary skill in the art also are within the scope of this invention. Thus, various changes and modifications may be made without departing from the spirit and scope of the invention. For instance, various components may be repositioned as desired. Moreover, not all of the features, aspects and advantages are necessarily required to practice the present invention. Accordingly, the scope of the present invention is intended to be defined only by the claims that follow.
