DETAILED DESCRIPTION
(13) The present invention is intended to provide a compact lightweight small sized portable movable structurally sound two in one treadmill/step deck conversion device supplemental simulate leg exercises and stair climb aerobic workouts. The main function of the device is to provide a safe and dependable apparatus with no replacement parts or assembly required components, no hinges or folding handles for storing or moving.
(14) Optional elements such as swing handles (1, 2, 3) and handrail (4, 5, 6) insuring user assist balance and safety. The pair of swing handles (FIG. 1, 7, 8, 9, 10), which would be held by the user's hands, are selectively pivoted to provide a natural arm swing simultaneously with the leg exercise as well as means of balance and stability while user engages in leg exercise.
(15) The step deck conversion (FIG. 1, 2, 3, 6) supplements simulation of stair climbing aerobic workout includes a handrail (FIG. 7, 9) which would be held by the user's hand providing balance and security while performing an invigorating cardio-vascular aerobic leg exercise workout.
(16) Riser plates on bottom of strut beam for structural purposes also correspond to riser blocks (FIGS. 11-2) lifting the entire unit higher such that knee lifts insure a more intense aerobics workout.
(17) As shown in FIG. 1 the device comprises a multi-purpose exercise apparatus with implied usage by means of easy access, compactness, lightweight and affordable design. Composed with a lightweight rigid exterior frame (18), horizontal dowel pins (16) with equally dimensioned dual hollow tube (8) threaded over each dowel pin (16) in need prevention of stalling and interference of foot motion once feet become parallel to one another in walking pattern. Swing handles comprise an upper (3) and lower section (1) joined by a cpvc coupling (2) with set screw (27) as shown in FIG. 9. Upper section (3) is permanently inserted in upper part of coupling (3). A smooth and rounding curvature (29) of top of upper section (2), FIG. 9 provides comfortable hand grip. Swing handles (FIG. 9) wedged in mounted handle/handrail assembly (11) to exterior front opposite side of strut beam (18) pivot back and forth in specifically design slots (19) allowing normal arm swings as well as stability and balance for user. Swing handles lower section (1) serves multiple usages with bottom part interchangeable as support brace in handrail (FIG. 9). Handrail construction is notated in FIG. 9 with support brace (5) to the smooth to touch top plate (4) with receptive post plates (6).
(18) The assembled handrail design (4, 5, and 6) is complete with attention to receiving holes for support post, must be in alignment for reception of bottom part of swing handle (1) insertion until intersection of bottom side of top plate (4) of handrail (FIG. 9). Set screws lock handrail securely to support post (1) for step deck conversion operation.
(19) The versatility of device and added benefit is its transformation from treadmill (FIGS. 1, 2 and 3) to a step deck (9) for supplemental simulation of a stair climbing aerobic workout. Pivotal clips (10) attached to top of inner strut (17) anchor step deck (9) into place. Inner strut beams hole placement (FIG. 5) requires strict adherence to holes alignment as to horizontal distance from center to center of dowel and hollow tube (8) thicknesses with both calculations combined in order to achieve a smooth roller foot contact surface when in active treadmill operation. The same calculation is mandated for strategic vertical step deck (9) placements procuring an uninterrupted perfectly level and evenly alignment of step deck (9) to top of inner strut beam for a safe stair stepping aerobic exercise when step deck (9) conversion is in active operation. For added concern, safety and protection to the user, FIG. 6 shows the bottom side of step deck (9) having two 90 degree metal brackets permanently affixed with bracket appendage slipping completely thru and between dowels 16 with rollers (8) locking step deck (9) firmly into place with pivoting clips on top and brackets underneath.
(20) To further entice the not so much exercising enthusiast or a prod motivation for the reluctant user to enter into a healthy exercising regiment, the device offers the ease of accessibility. Although easily stowed and out of sight, The Toteable Treadstep is extremely mobile and versatile due to its lightweight construction components and compact size.
(21) A horizontal smooth to touch handle bar permanently attached perpendicular to each end of each strut beam with a flush edge to edge joining to top of said strut beams allows ease of lift, maneuverability, and transporting. Furthermore, the compact design is based on a stride regulated in military and marching band of a 30 pace, or stride with treadmill proportioned to accommodate an even longer stride without fear of running out of plurality of roller foot contact surface area. As to the horizontal plurality of rollers foot contact surface the unit is of standard industry width.
(22) As an added incentive to manifest and induce even greater results, riser blocks (FIG. 11) are constructed in a similar fashion with conformity to design of device. Two stabilizing protruding dowel pins of equal perpendicular appendage (35) are equally spaced on center from end edges (34) and centered to width to be permanently fastened in the hole plate with the hole plate permanently joined to bottom plate (FIG. 12). Attention to hole alignment in structurally spaced support riser plates to reciprocate and coordinate dowel pins for consummation (FIG. 11). This raises the entire unit to a safe but higher level, perpetuating an even higher knee lift for simulate stair climbing activity resulting in a more invigorating, heart healthy, cardio-vascular aerobic workout when in step deck conversion operation.
(23) The Toteable Treadstep has adaptable modifications such as a workbench with an adjustable support brace for weights when user is engaged in a regiment of upper body strength training and torso muscle building and toning. The options are not really limited for this simple but efficient compact but economical portable but durable little device to grow and grow becoming a complete exercising arena.
