Collapsible exercise device

A collapsible exercising device, comprising:

• a vertical support member with an upper portion and a lower portion;
• a slide bar slidable along, and adjustably supported by said vertical support member, said slide bar having a first side and a second side;
• a set of inner rails, each of said set of inner rails having a first end and a second end, and having an inner side and an outer side, the inner side facing the other inner rail and the outer side being the side opposite to the inner side, the first end of one said set of inner rails being pivotally connected to the first side of said slide bar and the other said set of lower rails being pivotally connected to the second side of said slide bar;
• a set of outer rails, each of said set of outer rails having a first end and a second end, the first end of each of said outer set of rails being pivotally connected at a rail pivot point to the outer sides of the second end of the inner set of rails;
• a strut with a first end and a second end, the first end of said strut being pivotally connected to the lower portion of said vertical support member and the second end of said strut being pivotally connected to the inner sides of the second end of the inner rails at the rail pivot point;
• a user support platform with rollers engaging said inner and outer set of rails;
• pulley means;
• and
• connector means extendable through said pulley means and connecting to said user support platform;
• wherein the exercise device is foldable such that said vertical support member, said inner set of rails, said outer set of rails, and such strut are substantially parallel to each other;
• and
• wherein said inner and outer set of rails are extendable from said vertical support member and are alignable such that said user support platform is rollable along said inner and outer set of rails when said connector means is extended through said pulley means.

A collapsible exercise device, comprising:

• a vertical support member;
• a first set of rails, each of said first set of rails having a first end and a second end, the first end of each of said first set of rails being pivotally connected to, and adjustably supported by, said vertical support member;
• a second set of rails, each of said second set of rails having a first end and a second end, the first end of each of said second set of rails being pivotally connected at a rail pivot point to the second end of said first set of rails;
• a strut with a first end and a second end, the first end of said strut being pivotally connected to the rail pivot point;
• a user support platform with rollers engaging said first and second set of rails,
• pulley means;
• and
• connector means extendable through said pulley means and connecting to said user support platform;
• wherein the exercise device is foldable such that said vertical support member, said first set of rails, said second set of rails and said strut are substantially parallel to each other;
• and
• wherein said first and second set of rails are extendable from said vertical support member and are alignable such that said user support platform is rollable along said first and second set of rails when said connector means is extended through said pulley means and wherein said strut provides support to the rail pivot point when the first and second set of rails are so aligned.
