BACKGROUND
Nowadays indoor training devices, such as a spinning device, a treadmill training device and the like, suffer of some drawbacks the most disturbing of them in the daily routine of a user is the space they require in the home or the office where they are installed. An invention that allow for reducing of the space required for such training device when not in use is therefore of great importance.

It will be appreciated that for simplicity and clarity of illustration, elements shown in the figures have not necessarily been drawn to scale. For example, the dimensions of some of the elements may be exaggerated relative to other elements for clarity. Further, where considered appropriate, reference numerals may be repeated among the figures to indicate corresponding or analogous elements.
DETAILED DESCRIPTION OF THE INVENTION
Indoor training devices of the known art, such as a spinning device, require a considerable space for installation. While in use the space required for the device is unavoidable, the same space, when the device is not in use, is a nuisance, that disturb the user and other people who use that space and may even cause a potential user to refrain from installing such training device or remove pone that has already been installed.
The present invention discloses devices and methods for solving this problem, as well as other aspects, such as aesthetic aspects. Attention is made to FIG. 1, which is a schematic illustration of a collapsible training device 10 in its open position, according to some embodiments of the present invention. Collapsible training device 10 may comprise a collapsible main frame 12 comprising frame sub-units 12a, 12b, 12c and 12d, a pedal mechanism 14, a driving chain 16, a driving gear 18, a flywheel 20 and a seat 22. Collapsible 12 may comprise 3 or more sub-units. In the example depicted in FIG. 1 collapsible frame 12 comprises of a top sub-unit 12a, a back sub-unit 12b, a bottom sub-unit 12c and a front sub-unit 12d. The four sub-units 12a-12d are pivotally connected to construct a collapsible parallelogram frame in which sub-units 12a and 12c are substantially parallel to each other and sub-units 12b and 12d are substantially parallel to each other. Accordingly, the angle between each consecutive pair of sub-units of frame 12 may be changed. When frame 12 is in its fully unfolded position that angle is substantially a right angle, but these angles of the unfolded position may be set to a different set of angles as desired. When in unfolded position sub-units 12b and 12d may further function as supporting legs for device 10. Further, sub-unit 12b may further be used to affix device 10 a stabilizing steady part, such as a wall of a room (not shown) or the like. Front sub-unit may be used, as depicted in FIG. 1, for the installation of the user's handles. Top sub-unit 12a may also be used for supporting user's seat 22. Bottom sub-unit 12c may be used for supporting the pedal mechanism 14. Back sub-unit 12b may also be used to support driving gear 18 and flywheel 20 which may be installed with its turning axis substantially parallel to sub-units 12a and 12c when device 10 is in its unfolded position, thus allowing installation close to sub-unit 12b and minimal protruding when device 10 is in stowed away position. According to some embodiments of the invention the axis of the driven toothed wheel 24 in driving gear 18 may serve as the pivotal connection between sub-units 12b and 12c. 
Attention is made now to FIG. 2, which is a schematic illustration of a training device 10 in its collapsed position, according to some embodiments of the present invention. Based on the collapsible parallelogram construction of frame 12, when device 10 is collapsed to its up-right position, as depicted in FIG. 2, its size may be minimized, and if it is installed next to a wall, it may then be collapsed to a small up-right collapsed frame by the wall thus leaving most of its formerly occupied space free.
Attention is made now to FIGS. 3 and 4, which are a schematic illustration of a training device 20 in its open position and a schematic illustration of that training device in its collapsed position, respectively, according to some embodiments of the present invention. In the embodiment of FIGS. 3 and 4 the mechanism of driving flywheel 20 comprises a worm gear rotatable by pedal mechanism 14, a drive shaft 32 and a friction wheel 34. While in the depicted example of device 20 the method of driving the flywheel is different from that of device 10, aspects of the present invention addressing device and method for a collapsible training device are kept in both examples. It should be noted that either the driving mechanism of FIGS. 1 and 2 or that of FIGS. 3 and 4 the folding of frame 12 to a fully collapsed position or opening frame 12 to a fully opened working position are possible without any obstruction. In the driving mechanism embodiment of FIGS. 1 and 2 driven toothed wheel 24 and driving gear 18 may have their input axis coaxial with the corresponding pivot joining frame members 12b and 12c and thus allowing free opening or collapsing of frame 12. In the embodiment of FIGS. 3 and 4 friction wheel 34 is placed so that when frame 12 is closed to a collapsed position it departs from flywheel 20 and when frame 12 is opened to an open working position friction wheel 34 engages flywheel 20 to a rotatable coupling. Attention is made now to FIG. 5, which is a schematic illustration of a training device 10, 20 in a stowed away position, according to some embodiments of the present invention. In cases where not only saving of space of device 10, 20 when not in use is important but also the aesthetic aspect, device 10, 20 may be stowed away in a cabinet 50 built with front openings, such as doors 52, to allow easy pulling out or stowing way of device 10, 20 as required.
