DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to FIGS. 1 ̃4, a folding exercising machine in accordance with the present invention is shown comprised of an upright 1, two handlebars 2 and a wheel module 3.
The upright 1 has a top side provided with a display panel 11, a bottom side mounted with a bottom frame 15, and two horizontal pegs 12 perpendicularly extended from the periphery at two opposite sides and horizontally aligned in line at a suitable elevation between the display panel 11 and the bottom frame 15. Two connectors 13 are provided for pivotally securing the handlebars 2 to the horizontal pegs 12. The connectors 13 each have an axle sleeve 131 respectively coupled to the horizontal pegs 12 for allowing rotation of the connectors 13 relative to the horizontal pegs 12. A retaining member 14 is provided at the periphery of the upright 1 below the elevation of the horizontal pegs 12. The retaining member 14 has a retaining groove 141, and is mounted with a swivel hook 142. A connecting structure 16 is provided at the rear side of the bottom frame 15. The connecting structure 16 comprises an axle housing 161 transversely disposed at the top edge of the rear side of the bottom frame 15, and a lock screw 162 disposed adjacent to the axle housing 161. The lock screw 162 has its threaded shank 1621 suspending in the bottom frame 15. A transverse bar 17 is fixedly connected to the front side of the bottom frame 15, having two anti-slip blocks 171 respectively disposed at the two distal ends.
The handlebars 2 are curved rod members each having a bottom lug 21. Two pedal frames 22 are respectively pivoted to the bottom lugs 21 of the handlebars 2. Each pedal frame 22 has a footplate 221 fixedly mounted on the top side on the middle, and a pin 222 downwardly extending from the bottom side of the rear end remote from the bottom lugs 21 of the handlebars 2.
The wheel module 3 comprises a receiving structure 31 at the front side, a wheel 32 disposed adjacent to the receiving structure 31, two pedal cranks 321 fastened to the wheel 32 at two sides for pedaling by a user to rotate the wheel 32, two first sockets 322 respectively fixedly provided at the free ends of the pedal cranks 321 for receiving the pins 222 of the pedal frames 22, a transverse bar 33 transversely disposed at the rear side, two anti-slip blocks 331 respectively disposed at the two distal ends of the transverse bar 33 for positive positioning on a floor surface, a substantially U-shaped carrying handle 332 fixedly provided at the transverse bar 33, two second sockets 333 fixedly provided at the transverse bar 33 for receiving the pins 222 of the pedal frames 22, and a wheel guard 34 for protecting the wheel 32. The wheel guard 34 has a retaining ring 341 disposed at the top side. The connecting structure 31 of the wheel module 3 comprises two pivot holes 311 aligned at two opposite lateral sides for the mounting of a pivot pin 312, a connecting plate 313 obliquely disposed below the elevation of the pivot holes 311, and a screw hole 3131 on the connecting plate 313.
During installation, the connectors 13 are respectively fastened to the handlebars 2, and then the axle sleeves 131 of the connectors 13 are respectively coupled to the horizontal pegs 12 of the upright 1, and then the connecting structure 16 of the bottom frame 15 is connected to the connecting structure 31 of the wheel module 3 by fastening the receiving pin 312 to the pivot holes 311 of the receiving structure 31 of the wheel module 3 and the axle housing 161 of the connecting structure 16 of the bottom frame 15, and then rotating the lock screw 162 to thread the threaded shank 1621 of the lock screw 162 into the screw hole 3131 of the connecting plate 313, and then the pins 222 of the pedal frames 22 are respectively plugged into the first sockets 322 of the wheel module 3.
The display panel 11 is adapted to indicate speed, mileage, calories consumed and etc., when the user is operating the folding exercising machine to make exercise. Through the display panel 11, the user knows his (her) current exercising status. Subject to the indication on the display panel 11, the user can adjust the exercising amount as desired. When operating the folding exercising machine, the user can hold the handlebars 2 with the hands and alternatively push and pull the handlebars 2 while stepping on the footplates 221. When the user is stepping on the footplates 221, the pedal cranks 321 are driven to rotate the wheel 32. Because the anti-slip blocks 171 and 331 support the folding exercising machine firmly on the floor, the folding exercising machine does not vibrate during operation.
When not in use, as shown in FIGS. 5 and 6, unfasten the lock screw 162 from the screw hole 3131 of the connecting plate 313, and lift the pedal frames 22 to disengage the pins 222 from the first sockets 322 of the wheel module 3, and then lift the carrying handle 332 to turn the wheel module 3 inwards toward the upright 1 and to force the retaining ring 341 into engagement with the retaining groove 141 of the retaining member 14, and then hook the swivel hook 142 on the retaining ring 341, and then turn the pedal frames 22 downwards to engage the pins 222 into the second sockets 333, and therefore the folding exercising machine is locked in a collapsed status.
As stated above, the invention provides a folding exercising machine, which has the following features and advantages:
By means of the receiving structure 31, the wheel module 3 is pivoted to the axle housing 161 of the connecting structure 16 and then locked in position by the lock screw 162. When unfastened the lock screw 162, the wheel module 3 is turned inwards and closely attached to the upright 1. When collapsed, the retaining ring 341 of the wheel guard 34 is locked to the retaining groove 141 of the retaining member 14 by the swivel hook 142, and the second sockets 333 of the wheel module 3 are fastened to the pins 222 of the pedal frames 22. By means of the retaining member 14, the connecting structure 16, and the pins 222 to a three-point positioning status, the folding exercising machine is held positively in the collapsed condition. When in the collapsed status, the wheel module 3 is disposed close to the upright 1 and the bottom frame 15. At this time, the wheel module 3 has a relatively lower center of gravity, and will not vibrate upon an external force.
Although a particular embodiment of the invention has been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims
