I. BACKGROUND OF THE INVENTION
A. Field of Invention
This invention pertains to the art of methods and apparatuses for exercise devices, and more specifically to a mesh back support having an adjustable lumbar support.
B. Description of the Related Art
It is well established that proper diet and exercise are essential for a healthy lifestyle. During a cardiovascular exercise routine, the heart rate increases, which in turn causes a person's internal body temperature to rise. In order to cool itself off, the body perspires. While exercise devices provide fun and innovative ways to enjoy a work-out, it is desirable to have air circulation about areas of the exercise device that directly contact a person's body. Currently, the back and seat supports of exercise devices are fabricated from a poly-vinyl material, which serves as a cover over a foam cushion. This inhibits air circulation. Further, these back and seat supports are generally planar, so they do not provide the proper support to the lumbar area of the person's back. Further, by using a planar configuration with a seat support, it is common for a person to feel a tingling sensation in the mid-thigh area if a person's legs are not supported properly.
Based upon the foregoing, there is a need in the art for a support device to be used with exercise equipment that provides for increased air circulation and increased support to the body. The present invention provides for an exercise device having a mesh back support with an adjustable lumbar support.

Referring now to the drawings wherein the showings are for purposes of illustrating a preferred embodiment of the invention only and not for purposes of limiting the same, FIGS. 1-15 show the present invention.
The present invention is a support apparatus, such as a back support 10, which may be used on an exercise apparatus 11, such as a recumbent bicycle, but not limited thereto. As shown in FIG. 1, the exercise apparatus 11 may include a frame 12 and a pedal assembly 14 rotatably connected to the frame 12. A horizontal support member 16 is operatively connected to the frame. A front post 18 extends from the front portion of the frame 12, which may include handlebars 20 and a console 22, which may record speed, travel distance, calories burned, heart rate, etc. A shroud 24 is shown which covers the pedal assembly 14 as well as the other moving components (not shown). A sub-frame 26 is operatively connected to the horizontal support member 16. Further, a second set of handlebars 28 may encircle the sub-frame 26. The sub-frame 26 may be selectively moveable relative to the horizontal support member 16, namely, in the fore and aft direction. A seat 30 and the back support 10 may both operatively connect to the sub-frame 26 as shown in the FIGURES.
With reference to FIGS. 2-7, the support apparatus 10 is shown in further detail. The support apparatus 10 may include a frame 40 having a top 42, a bottom 44, and two lateral sides 46 extending between the top 42 and the bottom 44. The frame 40 may have a channel 48 defined about an interior perimeter 50 of the frame 40. The top 42, the bottom 44, 40 and the two lateral sides 46 of the frame define an opening 52. A membrane 54 or mesh fabric is operatively connected to a carrier 56, which is adapted to attach to the frame 40 via the channel 48. The membrane 54 has a first side 58 and a second side 60.
With continuing reference to FIGS. 2-7, the frame 40 forms a body support 62, which is formed by a lower arcuate portion 64 of each of the two lateral sides 46. The membrane 54 is adapted to stretch with the carrier 56 attaches to the frame 40 via the channel 48.
With reference to FIGS. 8-11, the sub-frame 26 will now be described in more detail. The sub-frame 26 further comprises a horizontal bracket 70. The seat 30 connects to the horizontal bracket 70 via a planar attachment bracket 72, which is angularly connected to the horizontal bracket 70. The horizontal bracket 70 has a base portion 74 and two side flanges 76 extending perpendicularly therefrom. The side flanges 76 and base portion 74 form a U-shaped cross-section. Of course, any other cross-section may be chosen with sound engineering judgment. The horizontal bracket 70 is adapted to be selectively moveable relative to the horizontal support member 16.
With continuing reference to FIGS. 8-11, an upwardly extending member 78 is connected to the horizontal bracket 70. The support apparatus 10, and in this embodiment the back support 10, operatively connects to the upwardly extending vertical member 78. As shown in FIG. 11, the upwardly extending member 78 and the horizontal bracket 70 define an angle α therebetween. Generally the angle may range anywhere from about 100 degrees to about 140 degrees, and preferably, angle α is about 120 degrees. This angle provides a more comfortable seating position for the user. The horizontal support bracket 70 has at least one hole 80 defined therein. The horizontal support member 16 further comprises a plurality of holes 82, as shown in FIG. 1. A pin 84 is adapted to pass through the hole 80 of the horizontal bracket 70 and one of the holes 82 of the horizontal support member 16 to selectively secure the sub-frame 26 to the horizontal support member 16. The upwardly extending member 78 may be adapted to move in the horizontal direction with horizontal bracket 70. The upwardly extending member 78 may have a bore 86 defined therein. As shown in the FIGURES, the upwardly extending member 78 may be square or rectangular in cross-section, but this is not required. Any cross-section chosen in accordance with sound engineering judgment may be chosen. The upwardly extending member 78 has at least one sidewall 88 having a plurality of holes 90 defined therein. This configuration enables the support apparatus 10 to be adjusted in a vertical direction as will be described in more detail below.
With reference to FIGS. 12-15, an adjustment mechanism 100 is shown. The adjustment mechanism 100 operatively connects to the frame 40 of the support apparatus 10. It is adapted to move relative to an associated member, such as the upwardly extending member 78 as previously described. As such, the body support 62 may be positioned to a preferred location to provide support to an operator's body, namely in the lumbar area. The adjustment mechanism 100 is in a spaced relationship with the second side 60 of the membrane 54 such that air can better circulate.
As shown in FIGS. 8-15, the adjustment mechanism 100 comprises a plate 102 with holes 104 for fasteners, such as a washer and screw. Any other attachment may be utilized with sound engineering judgment, such as bolts, and the same holes may be utilized. A square tube 106 is attached to the plate 102 via welding or any other means chosen with sound engineering judgment. Also, any other cross-section may be chosen with sound engineering judgment, such as a square, a circle, or other polygonal shape. A collar 108 is operatively connected to the square tube 106.
With reference now to FIGS. 1, 2, and 4, the support apparatus 10 further comprises a cross-member 120 extending between the two lateral sides 46 of the support apparatus frame 40. The cross-member 120 has a central base portion 122 and two oppositely disposed fork portions 124 extending from the base portion 122 and attaching to the two lateral sides 46. The two oppositely disposed fork portions 124 may be integrally formed with the base portion. As shown in FIG. 2, the plate 102 of the adjustment mechanism 100 is adapted to mate with the central base portion 122 of the cross-member 120. This provides adequate engagement of the adjustment mechanism 100 to the back support 10. As such, the back support may be moved in a vertical direction in order to adjust the body support 62 to the user's lumbar area. In order to move the back support 10, the pin 110 is loosened. The back support is adjusted vertically along the upwardly extending member 78. Once the desired position is reached, the pin 110 is turned within the collar 108 and goes through the hole of the square tubing 106 and engages one of the holes 90 of the upwardly extending member 78. The pin 110 may then be tightened to secure the back support 10 in place.
In another embodiment of the present invention, the support apparatus 10 may be a seat. In this embodiment the body support 60 may contact the user's legs a few inches above the knee. By providing the curved support in this area, circulation is maintained and the legs do not “fall asleep” or get a tingling sensation due to inhibited circulation.
The preferred embodiments have been described, hereinabove. It will be apparent to those skilled in the art that the above methods may incorporate changes and modifications without departing from the general scope of this invention. It is intended to include all such modifications and alterations in so far as they come within the scope of the appended claims or the equivalents thereof.
