       BACKGROUND OF THE INVENTION 
       [0005]    Field of the Invention 
         [0006]    This invention relates to improvements in an exercise bicycle. More particularly, the present exercise bicycle is a semi-recumbent style exercise bicycle with a desk that allows a person to comfortably stand between the seat, desk and pedals. 
         [0007]    Description of Related Art Including Information Disclosed under 37 CFR 1.97 and 1.98 
         [0008]    Many people have a desire to exercise but have limited time to exercise as they have additional responsibilities and activities that occupy their time. This is especially true for students of that spend large amounts of sedentary time reading, studying and other activities where they typically are in a seated or in a semi-recumbent position. One problem with exercise bicycles is that a person must contort their body as they lift their feet and legs off pedals, and bend around the display of an exercise bicycle. 
         [0009]    There have been some patents for exercise bicycles that focus on the exercise and they are generally constructed to allow a person to read a book or watch TV while they exercise. A number of patents and or publications have been made to address these issues. Exemplary examples of patents and or publication that try to address this/these problem(s) are identified and discussed below. 
         [0010]    U.S. Pat. No. 5,177,665 issued on Jan. 5, 1993 to Michael J. Frank et al., discloses a housing and vehicular support for portable computer with a mounting assembly for a small portable computer provides both a housing to receive the computer and releasably attach it to a vehicle steering wheel and connections for supplying electrical power to the computer. While this patent supplies a mounting for a computer, the patent is for a vehicle steering wheel and not for a piece of exercise equipment. 
         [0011]    U.S. published application 2003/0008752 was published on Jan. 9, 2003 for Hank Hsu discloses a structure of stationary bicycle. The stationary bicycle includes a machine base, a seat on the machine base for the sitting of the user, a back cushion mounted on the machine base and adapted to support the back of the user sitting on the seat, a pedal and damper unit installed in the machine base and adapted to impart a damping power against the external force employed by the user. This is a full recumbent bicycle and the structure restricts a person from standing between the seat pedals and desk. 
         [0012]    U.S. published application 2010/0206124 was published on Aug. 19, 2010 for Steve J. Ferrusi discloses a handlebar armrest. The armrest is for use on bicycle type handlebars of stationary bikes and bicycles used as indoor trainers. The device allows operator to rest forearms on padded and absorbent top surface for increased comfort and free use of hands and fingers while exercising. The person exercising can lean forward to use the computer while they exercise. This is a mounting for an actual bicycle and the pedals are located in the area where a person will stand. 
         [0013]    What is needed is an exercise bicycle configured in a semi-recumbent position with a movable desk that allows a person to exercise, work and easily stand. The proposed Xbike desk and exercise semi-recumbent bicycle provides the solution. 
       BRIEF SUMMARY OF THE INVENTION 
       [0014]    It is an object of the Xbike desk and exercise semi-recumbent bicycle to provide an exercise bicycle that has a desk to allow a person exercising to comfortably utilize the desk to use a computer, tablet, cell phone, draw, use a table or read a book. The desk is adjustable relative to the seat to configure at least one of the elevation of the desk, angle of the desk or the proximity of the desk relative to the chair and or the pedals. The desk can also be pivotable to allow the desk to be easily tilted towards the user when they are studying and tilted away from the user when the user wants to exit the exercise bicycle without climbing over the pedals. The position of the pedals allows a person the easily stand to use the desk without the obstruction of the pedals. 
         [0015]    It is an object of the Xbike desk and exercise semi-recumbent bicycle for the seat to be adjusted relative to the pedals. All people have different length from where they pedal to their preferred seated position. Some people prefer to sit on the edge of a seat while others may prefer to sit back in a seat. Their preferred position can also be effected by the type of reading, studying, working or playing they be use while they exercise. The dimension from the seat to the pedals is adjustable to accommodate these different desires. Further, a semi-recumbent bicycle provides hybrid between a racing style bicycle where a user leans forward and a recumbent bicycle where the person exercising is essentially seated horizontally. 
         [0016]    It is another object of the Xbike desk and exercise semi-recumbent bicycle to be constructed with crossing frame members where the seat and pedals extend from one arm/leg and the display and rear support extends from the other arm/leg. The two arm/legs cross through a central pivot that allows the bicycle to be folded for easier transportation and storage. The legs, or cross supporting leg, can include one or more wheels that allows the Xbike to be rolled to a desired location. 
         [0017]    It is still another object of the Xbike desk and exercise semi-recumbent bicycle for the person seated on the bicycle to exercise while they are seated. This allows a person to perform two separate activities. The amount of resistance can be adjusted to increase or decrease the difficulty to accommodate different levels of activity. The resistance can be from a variety of different mechanisms and can be manually adjusted or automatically adjusted. A recording or display mechanism can count distance, elapsed time, calories or other information. 
         [0018]    Various objects, features, aspects, and advantages of the present invention will become more apparent from the following detailed description of preferred embodiments of the invention, along with the accompanying drawings in which like numerals represent like components.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0025]      FIG. 1  shows an Xbike desk/exercise semi-recumbent bicycle  19  with the angles showing the preferred orientation of the components. In this figure, the crank  21  is shown entering into the resistance housing  20 . The resistance housing  20  provides the resistance that impedes rotation of the pedals  22  that turn the crank  21 . Because the person exercising on the bicycle  19  is dependent upon the pedals  22 , all of the geometry for the bicycle  19  is relative to the rotational axle of the crank  21 . There are adjustments on the frame that allows for personalization of the crank  21  seat  60  to desk  100  for the comfort of a person using the Xbike to study and exercise as well as allowing a person to easily mount and dismount the Xbike. 
         [0026]    The frame and seat are located in angular relationships to the crank  21 . From the crank  21  to one leg/arm of the bicycle  19  is at an angle 30 of 40 degrees but other angles as low as 20 degrees are contemplated. Angles of less 40 degrees places a person in a more recumbent position and makes standing more difficult and also places the person further from the desk  100 . 
         [0027]    The angle from the crank  21  to the front edge of the seat  60  is set at 50 degrees but other angles are contemplated. This provides a semi-recumbent bicycle  19  that allows an exerciser to essentially sit-up while they exercise without leaning forward or sitting with their feet in an elevated position that can be uncomfortable. These dimensions and angles are given as preferred embodiments, but other dimensions are contemplated to accommodate a user. 
         [0028]    The distance from the crank  21  to the center of the seat pad  61  position of the person exercising is shown as 19 inches 31 as the shortest length. This embodiment further includes side hand grips  70  with heart rate sensors  71  or contact. From this side view, the X frame is visible as two leg/arm components  80  and  90  that cross though a central axis/axle  23 . The crossed frame members allow the Xbike to be folded to make a smaller footprint for storage when it is not being used. The basic X frame is shown and describe in the following figure. 
         [0029]      FIG. 2  shows a simplified side view of the basic Xbike  19  frame. The housing for the loading system on the pedals  22  has been removed for simplicity in this figure. The X portion of the frame is easily seen with cross member  80  and  90  crossing through cross point pivot  23 . The cross member  80  and  90  are configured to fold through the pivot  23  for easier storage and transportation. Fixed feet or rollers  81  and  91  are connected to cross members secured to the ends of X members  80  and  90  respectively. 
         [0030]    The pivoting axle  21  is placed on member  90  and at a location above member  90  to reduce interference when folding the legs/arms  80  and  90 . A seat or chair  60  is placed on the end of arm/leg  90  and a desk  100  is placed on the other arm/leg  80 . This configuration leaves a fairly open region between the seat/chair  60  had the desk  100  for a person to stand between the pedals and the desk. This further allows a person to rest their feet on the ground or on one or more pedals  22 . 
         [0031]      FIG. 3  shows a perspective view of the Xbike  19  with the adjustable components. The perspective view shows the leg/arm  90  crossing through the split pieces  80 . The horizontal legs  81  and  91  are shown secured to legs/arms  80 ,  90  respectively. A brace  89  is secured between leg/arm  80  at point  87  and leg/arm  90  at point  88 . The brace  89  can be disconnected to collapse or fold the legs/arms  80 ,  90 . The pedals  22  are shown connected to the axle and entering housing  20 . The leg  81  has a wheel  72  to allow the Xbike to be rocked onto the wheel for easier transportation. The wheel is elevated when the Xbike is being used to prevent the Xbike from rolling to a different location when the Xbike is being used. Other legs  91  can have a height or leveling adjusting device  73  to account for variations in a floor surface. 
         [0032]    A knob  24  or other control mechanism adjust the load/resistance on the pedals  22 . This allows a person to perform two separate activities. The amount of resistance can be adjusted to increase or decrease the difficulty to accommodate different levels of activity. The resistance can be from a variety of different mechanisms including, but not limited to a frictional, a prony brake, magnetic, a fan, an alternator or a generator. A recording mechanism can count distance, elapsed time, calories or other information and can be displayed on a display  102  shown integrated into the desk  100 , but can be separate from the desk  100 . 
         [0033]    The desk  100  is shown with cup holders  101 , but the cup holders may be optional and/or the desk can include other items elements, including, but not limited to, a radio, TV, phone, USB port, charger, phone charger, outlet, camera and a portable device charger. The desk can be adjusted for elevation using knob  103  or can be adjusted for an angle and/or can be movable towards or away from the seat  60 . The desk has a 6-way adjustment  104  that allows the angle of the desk to be quickly and easily adjusted to alter the angle, height and position of the desk to allow a person to easily enter and exit the seat of the Xbike. 
         [0034]    The seat  60  is shown with side-mounted grips  70  that have a heart rate monitor  71 . The heart rate monitor communicated with the display  102  to identify the heart rate. It is also contemplated that the resistance from the loading system in the housing  20  can be automatically controlled based upon the heart rate of the user. The seat  60  is shown with a back rest  65  supported on member(s)  66 . The seat has an adjustment mechanism  62  that allows the seat or chair  60  to move on the arm/leg  90 . The seat or chair  60  can be moved towards and away from the pedals  22  and the desk  100  for the comfort of the person exercising or using the desk  100  or for a person exercising as they use the desk  100 . 
         [0035]      FIG. 4  shows a person  18  on the Xbike in a semi-recumbent seated position with their feet on the pedals. From this view the person  18  is shown in a comfortable position where they can both exercise and use a computer on the desk  100  at the same time. 
         [0036]      FIG. 5  shows a person  18  standing between the seat and the desk with the pedals being clear of the standing position. This allows the person  18  to comfortably stand and operate the computer on the desk  100 . The desk  100  has been slightly articulated to accommodate the erect orientation of the person. There is sufficient clearance between the seat and the pedals and the resistance housing as the person  19  stands. 
         [0037]      FIG. 6  shows the clearance  17  for mounting and dismounting the Xbike. The user can easily enter between the seat and pedals and desk. To use the desk and/or pedals to study read or perform other activities. 
         [0038]    The Xbike is for a desk and exercise semi-recumbent bicycle that includes a foldable frame having at least two crossed components where the crossed components cross through a central pivoting axle. The foldable frame further has a pair of pedals on an axle connected to a resistance device on a first side of the first of the two crossed components. The seat or chair is mounted on a second side of the first of the two crossed components. There is a leg on a first side of the second crossed components, and there is a desk on a second side of the second crossed components. 
         [0039]    The desk is adjustable relative to the pair of pedals. The seat or chair is adjustable relative to the pedals. The angle from the axle to a seat or chair is up to 40 degrees. The length from the axle to the seat or chair is 19 inches or less. The angle from the axle to a seat or chair is up to 40 degrees. The desk is independently adjustable for height relative to the seat or chair. The desk is independently adjustable at an angle to the seat or chair and the angle moves the desk closer and further from the seat or chair. The desk is independently adjustable toward and away from the seat or chair. The adjustments to the desk relative to the chair allows a user the ability to position the desk at a position that is optimal for using the desk to read, study or use a computer, tablet or phone while they exercise. 
         [0040]    The desk can include, but is not limited to, having a radio, a cup holder, a TV, a phone, an USB port, a charger, a phone charger, a WiFi hub, a Bluetooth interface, an outlet, a light, a camera and a portable device charger. 
         [0041]    The desk and exercise semi-recumbent bicycle according to further includes an adjustment mechanism that alter a resistance to the pair of pedals. The resistance can be manually or automatically adjustable. The resistance mechanism can be a variety of forms or mechanism including, but not limited to a frictional mechanism, a prony brake, a fan, magnetic, an alternator, eddy current, a generator and other resistance types that provide resistance to rotation of the pedals to provide resistance to the user to allow the user to exercise. 
         [0042]    The desk and exercise semi-recumbent bicycle can include at least one handle with a heart rate monitor contact. The Xbike can have a wireless heart rate monitor. The resistance mechanism can automatically control the resistance mechanism connected to the pair of pedals to control a reading from the heart rate monitor.
