DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Though a mini-bike is illustrated in Figs. 1 through 10 for a first and a second preferred embodiment of the present invention, said two preferred embodiments shall be taken as to include that for a skateboard, a child tricycle or a bicycle for the same mechanism applies to all of them.
Figs. 1 through 8 show a fist preferred embodiment of the present invention. As illustrated in Figs. 1 and 2, the present invention includes a head tube ( 1 ), a pivoted inner tube (2), two pieces of retainer (3) (6), a lower section of a stem (4), a joint (5), an upper section of the stem (7) and a handle (8).
Wherein, a section in proper length protrudes upwardly from the pivoted inner tube (2) in the head tube ( 1 ). A slit (21 ) is provided axially on the wall of the protruded section and an end of the protruded section is engaged to a retainer (3) with a fast wrench (31 ). A threaded hole (32) is provided on a ring of the retainer (3) to couple a axing bolt (33) to retract into the slit (21) in the pivoted inner tube (2).
A joint (5) is provided at the lower end of the lower section of the stem (4) and inserted into the pivoted inner tube (2). Said joint (5) is comprised of an upper part (51 ) and a lower part (52) pivoted to each other. Both said upper part (51 ) and lower part (52) are mutually inserted into a pivot (521 ) using a protrusion plate (511). A rivet (53) is used to pass through to connect both of the upper part (51 ) and the lower part (52). Two recessed longitudinal slides (512) and (522) formed respectively on both outer sides of the upper part (51 ) and the lower part (52) facing in the direction of the slit (2I ) of the pivoted inner tube (2) for receiving the fixing bolt from the retainer (3) retract and hold against the matching recessed slide (512) (522). Meanwhile the lower part (S2) of the s joint (S) in normal condition retracts into the pivoted inner tube in position. A
hole (S23 ) is provided wherein either relative inner end of the upper part (S
1 ) or the lower part (S2) of the joint (S) (as illustrated, the lower part (S2)) to accommodate a tenon (S4). The tenon (S4) is comprised of a coil (S41 ) holding against a steel ball (S42) and a chamber (S43) containing said coil (S41 ) and steel ball (S42) as illustrated in Fig. 3. The protruded plate (S 11 ) on the upper part (S 11 ) is provided with a recess (S 13) at where corresponding to the steel ball (S42) of the tenon (S4). Furthermore, a slit (41 } together with a hole (42) is each provided axially on both symmetrical sides of the upper end of the lower section of the stem (4) to insert into another retainer (6) having a fast wrench (61 ).
A threaded hole (62} is provided on the retainer (6) relatively to the hole (42} in the lower section of the stem (4) to couple a fixing bolt (63). The upper section of the stem (7) passes through the retainer (6) and is inserted into the lower section of the stem (4). The upper portion of the upper section of the stem (7) 1 S retracts forwardly and upwardly at a certain inclination to be fixed to a lateral section of the body of the handle (8) with handles (81 ) respectively provided to both ends of the lateral section.
Now, referring to Fig. 3, the section protruding upward from the pivoted inner tube (2) is inserted into the retainer (3) having a fast wrench so to accommodate inside the pivoted inner tube (2) with the joint (S) connected to the lower end of the lower section of the stem (4). The position bolt (33) of the retainer (3) worms into the slit (21 ) and holds against both recessed slides (S 11 ) (S22) of both upper and lower sections (S 1 ) and (S2) of the joint (S).
Accordingly, the lower section of the stem (4) is restricted from turning relatively to the pivoted inner tube (2) to facilitate its sliding movement for either retracting or retreating. In addition, both of the upper part (S 1 } and the lower part (S2) of the joint are made standing upright and held in position with the steel ball (S42) from the tenon (S4) inserted in the slit (S 13), and then pressed into and concealed in the pivoted inner tube (2). Meanwhile the fixing bolt (33) from the retainer (3 ) is inserted into the slide (S 12) of the upper end (S 1 ) to further hold both parts of the joint (S) in position. The fast wrench (31) from the retainer (3) is used to tightly fasten and lock up the pivoted inner tube (3) relatively to the lower section of the stem (4), thus forming a pivoting structure concealed in the pivoted inner tube (2) of the head tube.
Upon folding up the handle as illustrated in Fig. 4, release the fast wrench (61 ) from the retainer (6) at the upper end of the lower section of the stem (4).
The upper section of the stem (7) inserted inside the lower section of the stem (4) retreats into the stem for a length reduction while the handle (81 ) can be put at a comfortable height for a rider of the pedal cycle by proper adjustment of the length. The fast wrench (31 ) on the pivoted inner tube (2) is released to free the retainer (3) from restricting the pivoted inner tube (2), thus to release the joint (S) on the lower end of the lower section of the stem (4). As illustrated in Fig.
S, the lower section of the stem (4) is capable of pulling up the joint (S) to expose certain portion of the upper part (S 1 ) of the joint (S) from the upper end of the pivoted inner tube (2). Referring to Fig. 6, (when both of the handle and the pivoted inner tube (2) are turned sideways), the lower section of the stem (4), the upper section of the stem (7) and the substantial part of the body (8) of the handle (81 ) are folded and resting against the center of the frame as illustrated in Fig. 7 to achieve a compact volume for easy storage and carriage. Once the lower section of the stem (4) retracts to its extreme, the fixing bolt (33) of the retainer (3) will hold against the end of the slide (S22) in the lower part (S2) of the joint (S) to prevent the lower section of the stem (4) from being pulled out to leave the pedal cycle.
The body (8) of the handle (81) and the handle (81) connected to the upper section of the stem (7} can be varied as illustrated in Fig. 8. Wherein, the retracted upper part of the upper section of the stem (7) curved forwardIy and upwardly can be changed to a straight section with its upper end connected in position to the lateral section of the body (8) of the handle (81 }. Both ends of the lateral section are curved forwardly to form a shorter section slightly warping upward to provide a pair of horn like handles (82).
A mechanism to restrict the upper section of the stem (7) from revolving may be designed in the planning of the extension by the upper section of the stem (7) in relation to the lower section of the stem (4) to achieve an oriented extension longitudinally by the upper section of the stem (7) as illustrated in Figs.
9 and 10 for a second preferred embodiment of the present invention. Wherein, a fixing member (65) may be inserted through a pivoted pin shaft (64) between open ends of the ring of the fast wrench (61 ) from the retainer (6) on the lower section of the stem (4). A tapered stopper {651 ) is formed at the end of the inner side of the slit (41 ) in the lower section of the stem (4) while a longitudinal slide (71 ) is formed on the upper section of the stem (7) at where corresponding to the tapered stopper (651 ) at the fixing member (65). The upper section of the stem {?) is restricted from fuming without compromising its smooth operation of extension since the slide (71 ) and the tapered stopper (651 ) are holding against each other.
