referring to fig1 and 2 , the present invention comprises a base board ( 1 ) as the body , two guiding rails ( 111 ) formed on the base board ( 1 ) and a pair of pedals ( 2 ) provided with rollers ( 21 ) that roll in the rails ( 111 ). the base board ( 1 ) includes two boards ( 11 ) joined by a hinge ( 12 ). the pair of guiding rails on each board ( 11 ) also aligns with each other to form the continuous guiding rails ( 111 ) for the base board ( 1 ). as illustrated in fig3 a plurality of slots ( 13 ) are provided on the back side of the boards ( 11 ) at the hinged joint . at both ends of slots ( 13 ), a hole ( 131 ) larger in diameter than the width of the slot ( 13 ) is provided to facilitate the threading of an elastic rope ( 14 ) into the slot ( 13 ), with both ends ( 141 ) of the elastic rope ( 14 ) respectively fitting into the holes ( 131 ). furthermore , at both ends of the base board ( 11 ), an eyelet ( 17 ) is fixed to receive a tension rope ( 3 ) comprised of a handle ring ( 31 ) and a hook ( 32 ). the hook ( 32 ) hooks the tension rope ( 3 ) to the eyelet ( 17 ) on the board ( 11 ) so as to allow both ends of the baseboard ( 1 ) to form a base for the tension rope ( 3 ). a pair of openings ( 112 ) is provided at each end of the board ( 11 ) to receive a stop ( 15 ). the stops ( 15 ) prevent the pair of pedals ( 2 ) from falling out of the guiding rails ( 111 ) on the base board ( 1 ). multiple pairs of regulation openings ( 113 ) are also provided at a proper spacing on the board ( 11 ) as options for the insertion of second stops ( 16 ) depending on the sliding range of the pair of pedals ( 2 ) on the base board ( 1 ) desired by the user . on the inner edge of each of the pedals ( 2 ) is a plurality of eyelets ( 22 ) to receive elastic ropes ( 23 ) to thread by fixing ends ( 231 ) so as to connect both pedals ( 2 ). a key hole ( 24 ) is provided at both ends of the pedal ( 2 ) to receive a handle ( 4 ) for the pedal ( 2 ). a slot ( 114 ) is formed on each wall of the guiding rail ( 111 ) of the base board ( 1 ). a protrusion edge ( 212 ) provided on both ends of a roller frame ( 211 ) of the roller ( 21 ) of the pedal ( 2 ) is received in slot ( 114 ) of the guiding rail ( 111 ) as illustrated in fig4 . now referring to fig5 a and 5b , the present invention permits a sliding movement for a user to work out . depending on individual physical conditions the user may select the proper number of elastic ropes ( 23 ) to thread between the pedals ( 2 ) to create a resistance / restoration force . the user then steps on the pedals , and spreads his feet toward the ends of the base board ( 1 ). also as illustrated in fig6 a and 6b , the stop ( 16 ) can be used to fix one pedal in position . protrusions provided on the surface of the pedal ( 2 ) provides a plantar massaging action . as illustrated in fig7 in another exercise , the user steps on the boards ( 11 ) of the base board ( 1 ) and with both hands pulls the tension ropes ( 2 ) fixed onto the base board ( 1 ). this allows the user to work out by twisting his waist in conjunction with stretching . furthermore , as illustrated in fig8 the user may stand on either of the boards ( 11 ) of the base board ( 1 ), then mount a rope ( 5 ) without elasticity to replace the tension rope ( 3 ). the rope ( 5 ) is attached by its ring ( 51 ) in the eyelet ( 17 ) provided on the other board ( 11 ). as the user raises and lowers the rope ( 5 ), the other board ( 11 ) folds at the hinge ( 12 ). depending on the individual requirements , if a heavier work out is desired for the arm , the drawing force may be adjusted by increasing the number of the elastic ropes ( 15 ) provided at the bottom of the board ( 11 ). meanwhile , the force to lift up the board may also be adjusted by changing the number of the elastic ropes ( 14 ) binding both boards ( 11 ). as illustrated in fig9 the user may fix either pedal ( 2 ) with the stops ( 15 , 16 ), kneel down on the other pedal ( 2 ) which is mobile , and place both hands on the fixed pedal ( 2 ) to stretch the body to work out the abdomen . to protect the knees , a cushion ( 25 ) may be provided on the mobile pedal ( 2 ). the user may in the same posture hold onto both handles ( 4 ) provided on the fixed pedal ( 2 ). when the exerciser of the present invention is not in use , all components and elastic ropes binding both boards ( 11 ) may be removed from the base board ( 1 ) to fold up both boards ( 11 ) to reduce its length to half of the original length for facilitating storage or transport . the above disclosure is not intended as limiting . those skilled in the art will readily observe that numerous modifications and alterations of the device may be made while retaining the teachings of the invention . accordingly , the above disclosure should be construed as limited only by the restrictions of the appended claims .
a multi - purpose sliding exerciser including a base made of two boards butted and hinged to each other . the hinge joint is threaded with a plurality of elastic ropes . at each end of the base is a tension rope . a plurality of insertion holes are also provided in pairs on the base to restrict the pedals &# 39 ; slide path . the multipurpose sliding exerciser allows the user to remove the elastic ropes threaded through the back side of the base so as to fold up the boards for easy storage or transport .
