Multi-functional sporting equipment

A multi-functional sporting equipment system comprising:

• a front housing having a front frame covered with a cover, said frame having a hollow portion therein for receiving a storage box, a recessed portion disposed at a rear portion of said front housing having a lug member;
• a rear housing having a rear frame covered with a cover, said lug member disposed at a recessed portion of said rear housing;
• a connecting lever disposed at an upper connecting portion of said recessed portions to connect the front housing and rear housing;
• a pair of parallel juxtaposed supporting racks connected by said connecting lever at their middle portion, a plurality of rollers provided on said supporting rack, said supporting rack being attached to said front frame and said rear frame through a plurality of connecting shafts;
• a bottom protecting cover disposed at a bottom of the connecting portion wherein when the rear housing is folded onto said front housing a protecting surface will be formed, said bottom protecting cover comprising a folded edge portion with a drive shaft comprising a gear disposed at a middle portion thereon, said gear being controlled by an actuating device installed in said rear housing, and said bottom protecting cover further comprising a hook portion at a top rear portion thereof;
• a sliding block having a projected plate at its bottom edge, said projected plate extending into a slot formed in said front housing, said projected plate comprising an elongate slot being provided wherein a pin is inserted into the elongate slot through the slot of the front housing, a row of rollers disposed at the underside of the projected plate, the sliding block being movable on the front housing, the front housing further comprising a positioning hole provided at an upper position of the elongate slot of the projected plate wherein a positioning member can be inserted into the hole to adjust the position of the sliding block;
• a pair of storage boxes disposed in a hollow portion on both sides of the front housing, a second hooking portion disposed at the upper portion of the storage boxes, said second hooking portion retained by a retaining plate which is disposed within a third housing and controlled by a knob, a row of teeth provided at the inner sides of the storage box, said teeth meshed with an actuating device when the storage boxes are stored, wherein said actuating device is rotated to reserve potential energy such that when the hooking portion is released from the retaining plate the potential energy released by said actuating device pushes said storage boxes to an erect position, said storage boxes comprising a dovetail slot on the bottom and a retractable tube disposed therein such that said retractable tube can be pulled up from said front housing;
• and,
• a pedal covered by the rear housing when the pedal is stored, the pedal being controlled by a knob having a cone surface disposed at the front portion of said housing, when the knob is pressed the cone surface of the knob presses a spring post to the left side to release a retaining post from a slot hole, the pedal supported by a pivoting ring member at its inner portion, an elastic post which is disposed at the front end portion pressed to a central post of a positioning device, the positioning device fixed to an adjusting socket which is disposed at the rear housing and pivoted to a bottom socket through a fourth shaft member comprising a U-shaped supporting bracket pivoted to the sides of the pedal.
