DETAILED DESCRIP¾ON OF EMBODIMENTS Reference is now made to Figs. l and IB, which illustrate cycling apparatus 10, constructed and operative in accordance with1 an embodiment of the present invention.
Cycling apparatus 10 in general may include one or more front wheels 12 and one or more rear wheels 14 rotatably mounted on axles 16 on a frame 18. For example, without limitation, cycling apparatus 10 may be configured as a tricycle with two front wheels 12 and one rear wheel 14, or alternatively, as a tricycle with one front wheel 12 and two rear wheels 14, or as another alternative, as a quadrocycle with two front wheels 12 and two rear wheels 14.
A riding seat 20 may be attached to frame 18, such as by means of a seat post 21 slidingly mounted in a tube 22, as is extremely well known in the art. A drive mechanism 24 is coupled to one or more of the wheels 12 or 14 for driving the cycling apparatus, such as a pedal, gear and chain drive extremely well known in the art.
One or more handlebar posts 26 mayi e; attached to a portion of frame 18, which are movable between first and second att|^¾n¾ ( orientations, as will be described more in detail below. The handlebar post 26 may t^e journaled in a handlebar post tube, which in Fig. 1 A is the front post tube 27, as is kriown in the art. A carrier member 28 may be attached to frame 18 (e.g., to handlebar post 26) for carrying a child and/or an object (e.g., carrier member 28 may be a child seat or a shopping container). As an example, there may be two handlebar posts 26 separated by a space, wherein at least a portion of the carrier member 28 is disposed in the space between the handlebar posts 26.
In the first attachment orientation, shown in Fig. 1 A, there is a reference distance C defined between the handlebar post 26 and the axle(s) 16 of the front wheel(s) 12. A reference angle B is defined about the axle 16 of the front wheel(s) 12 between a horizontal plane and the handlebar post 26 (or alternatively between the horizontal plane and the front post tube 27). The reference angle B about the front axle 16 may be in the range of 45°-90°, but is not at all limited to this range. In the second attachment orientation, shown in Fig. IB, handlebar pQSt(sj) 26 has (have) been moved to another portion of the frame 18 (e.g., hiserted i i ¥ sideways extension of tube 22). In this orientation, the reference distance between' Handlebar post 26 and axle 16 is different from the first attachment orientation, that is, it is no longer C but some distance C".
Carrier member 28 has also the new position together with handlebar post(s) 26. That is, carrier member 28 has been moved from the first attachment orientation to the second attachment orientation. The distance between carrier member 28 and axle 16 is different between the first and second attachment orientations, too. Seat 20 has been lowered in tube 22 or has been moved to another portion of frame 18.
In the first attachment orientation, cycling apparatus 10 is in a rider orientation drivable by a rider (not shown) sitting on seat 20 and powering the drive mechanism 24, just like a "regular" bicycle or tricycle. In the second attachment orientation, cycling apparatus 10 is in a stroller orientation wherein the handlebar post(s) 26 is (are) arranged carrier member 28 is located over the front wheel 12, whereas in the second attachment orientation, the center of gravity of the carrier member 28 has been shifted rearward towards the rear wheels 14.
Moreover, the steering of the cycling apparatus 10 is different in the two orientations. In the first attachment orientation, that is, the rider orientation, the handlebar post(s) 26 may be in steering linkage with the front wheel(s) 12 to steer them, as in a bicycle or tricycle. However, in the second attachment orientation, that is, the stroller orientation, the handlebar post(s) 26 are not in steering linkage with the front wheel 12. There are two rear wheels 14 and one front wheel 12 and, as in conventional strollers, the front wheel 12 either turns freely or may be constrained to roll in a straight line. Steering may be accomplished as with conventional strollers; namely, by shifting the weight on the rear wheels 14 and turning. ■ It is noted that seat post 21 extends ;¾ift-her out of the tube 22 in the rider orientation than in the stroller orientation. '1 Reference is now made to Figs. 2A and 2B, which illustrate an embodiment similar to the cycling apparatus of Figs. 1A and IB. In this embodiment, the handlebar post(s) 26 may be moved in translatory motion from the first to second attachment orientations by means of an adjustment assembly 30 coupled to the handlebar post(s) 26. The adjustment assembly 30 may include a link member 32 pivotally coupled to the handlebar post(s) 26 and pivotally attached to frame 18 that may be pivoted about pivot 33 to move between the first and second, attachment orientations. The adjustment assembly 30 may be locked into place at each of the attachment orientations, such as by "clicking" into detents as is well known in the art. Here, too, carrier member 28 has been translated to the new position together with handlebar post(s) 26, and seat 20 has been lowered in tube 22 or has been moved to another portion of frame 18.
Reference is now made to Figs. 3 A and 3B, which illustrate an embodiment similar to the cycling apparatus of Figs. 1A and IB. In this embodiment, a portion of the handlebar post(s) 26 may be rotated a out^ )ivot 34 to move between the first and second attachment orientations. The handlebar post 26 is telescopically extendable. In this embodiment, a reference angle B' is defined between the horizontal and the handle bar tube 27 about pivot 34 (or alternatively, about the front axle 16). The reference angle B' may be in the range of 45°-90° (e.g., 72°-78d), but is not at all limited to this range. In the second attachment orientation, shown in Fig. 3B, the reference angle B' has changed to a reference angle B", which may be in the range of 5°-70°, but is not at all limited to this range, The handlebar post 26 is rotatable about the pivot axis of pivot 34 generally parallel to the rotational axis of the front axle 16, when moving between the first and second attachment orientations. Thus the handlebar post 26 changes its rotational orientation about the axle 16 between the first and second attachment orientations.
In the second attachment orientation, that is, the stroller orientation, pivot 34 may be locked in place (e.g., by means of a pawl and detent, not shown) so that the handlebar post(s) 26 are not in steering linkage with tlie front wheel 12. Instead, the front wheel 12 either turns freely or may be constrained ¾te|r,c>lL in a straight line (as in the previous embodiments). Once again, there are two rear wheels 14 and one front wheel 12 and the cycling apparatus is steered as in conventional strollers.
Carrier member 28 slides along the post 27 between the first and second attachment orientations, such as by means of a glide element 36 that slides on post 27 or on a track formed in post 27.
Reference is now made to Figs. 4A and 4B, which illustrate another embodiment similar to the cycling apparatus of Figs. 3 A and 3B. In this embodiment, handlebar post 26 may be one and the same as post 27, because handle bars 38 extend from carrier member 28 instead of the post. There is no need for handlebar post 26 to telescopically extend from post 27. Handlebar post 26 rotates about pivot 34 between the first and second attachment orientations, and once again, carrier member 28 slides along the handlebar post 26 between the first and second attachment orientations, such as by means of a glide element 36 that slides on handlebar post 26 or on a track formed in the post 26.
Reference is now made to Figs. 5A and 5B, which illustrate another embodiment similar to the cycling apparatus of Figs. 3 A and 3B. In this embodiment, carrier member 28 is mounted on handlebar post(s) 26 and handle bars 38 extend from carrier member 28 (instead of the handle bar(s) 26). As previously 1 described, handlebar post(s) 26 may be rotated about pivot 34 between the first and secp'hd- ttachment orientations Reference is now made to Figs. 6A anHr6B, which illustrate another embodiment of the invention. In this embodiment, handlebar post(s) 26 may be both rotated and translated between the first and second attachment orientations by means of an adjustment assembly 40 coupled to the handlebar post(s) 26. The adjustment assembly 40 may include a bar member 42 pivotally coupled to the handlebar post(s) 26 at a pivot 44 and pivotally attached to frame 18 at a pivot 46. The adjustment assembly 40 may be pivoted about pivots 44 and 46 to move between the first and second attachment orientations. The adjustment assembly 40 may be locked into place at each of the attachment orientations, such as by "clicking" into detents as is well known in the art. Again, carrier member 28 has been translated to the new position together with handlebar post(s) 26, and seat 20 has been pivoted about pivot 46 to move out of the way in the second attachment orientation. Handle bars 48 may pivotally extend from carrier member 28. In the embodiment of Figs. 6A and 6B, the handlebar post 26 spatially translates and also changes its rotational orientation about the axle 16 between the first kiad second attachment orientations.
' .'" '¾ $$ ;' ; . . Reference is now made to Figs. ΊΚ-ΊΌ, which illustrate cycling apparatus 50, constructed and operative in accordance with an embodiment of the present invention. Cycling apparatus 50 is shown in Fig. 7A in a rider orientation with carrier member 28 (child seat) facing forward in the riding direction.
In this embodiment, handlebar post(s) 26 may be rotated about front axle 16 and may be locked into place at each of the attachment orientations, such as by "clicking" into detents as is well known in the art. In the first attachment orientation (Fig. 7A), the handlebars 26 are tilted away from an upright position toward the seat 20. In the second attachment orientation (Fig. 7B) the handlebars 26 are tilted away from the upright position and away from the seat 20 (at a different angular orientation with respect to the front axle 1 ). Handlebar post 26 may be pivoted about a pivot member 54 attached to frame 18. In Fig. 7B, which illustrates the , stroller orientation, seat 20 is folded downwards. The pushing direction of the stroller is opposite to the riding direction. Carrier member 28 (child seat) has changed lts-cjenter of gravity with respect to axle 16 - - .■ and now faces the pushing direction.
Alternatively, as shown in Fig. 7C, the seat 20 may be moved downwards in support tube 22. Another alternative is shown in Fig. 7D. Here seat 22 has been removed and placed elsewhere on the frame 18.
Figs. 7E and 7F show the cycling apparatus 50 respectively in the rider-powered and stroller orientations, this time with the carrier member 28 being a carrier basket.
It is noted that by pivoting handlebar posts(s) 26 about the front axle 26, the distance between the front and rear wheels 12 and 14 changes between the first and second attachment orientations. It is also noted that carrier member 28 faces in a first direction when the cycling apparatus 50 is in the rider orientation, and faces in a second direction opposite to the first direction when the cycling apparatus 50 is in the stroller 62 and a second portion 64 that are pivoted to one another at a pivot 66. The action of pivoting handlebar post(s) 26 about front axle 16 and first portion 62 pivoting about pivot 66 moves cycling apparatus 60 between the first and second attachment orientations. Here again the distance between the front and rear wheels 1 and 14 changes between the first and second attachment orientations.
Reference is now made to Figs. 9A and 9B, which illustrate cycling apparatus 70, constructed and operative in accordance with another embodiment of the present invention. In this embodiment, the frame of cycling apparatus 70 includes a first portion 72 that telescopically extends in and out of a second portion 74. The handlebar post(s) 26 may be pivoted about a pivot 76 in order to rotate the handlebar post(s) 26 together with carrier member 28 and thereby change the iifijgje of the handlebar post(s) 26 with respect to the vertical and change the direction ¾ ¾¾¾ t¾r imember 28. In this manner, cycling apparatus 70 may be moved between Hfirst and second attachment orientations. Additionally, first portion 72 may be separately moved telescopically in and out of second portion 74 to change the wheel base, i.e., the distance between the front and rear wheels 12 and 14. Alternatively, the action of pivoting handlebar post(s) 26 about a pivot 76 may move first portion 72 telescopically in and out of second portion 74, and move cycling apparatus 70 between the first and second attachment orientations. The distance between the front and rear Wheels 12 and 14 changes between the first and second attachment orientations, and the child seat changes its center of gravity.
Reference is now made to Figs. 1 OA- IOC. Any of the above embodiments of the present invention may be constructed of dual front frame members 80 pivoted to the rest of the frame at pivots 82. This permits folding the cycling apparatus from a non-folded position (Fig. 10A) to a semi-folded position (Fig. 10B) and a fully folded position (Fig, IOC).
Reference is now made to Fig. 11 A, which illustrates cycling apparatus 100, constructed and operative in accordance with another embodiment of the present invention.
Cycling apparatus 100 may have features similar to cycling apparatus 10, these features being designated in the drawings by the same numerals. Accordingly, cycling apparatus 00 may in general include one or more front wheels 12 and one or more rear wheels 14 rotatably mounted on axles 16 on frame 18. For example, without limitation, cycling apparatus 10 may be configured as a;.'fricycle with two front wheels 12 and one rear wheel 14 (the currently preferred arrangement), or alternatively, as a tricycle with one front wheel 12 and two rear wheels 14, or as another alternative, as a quadrocycle with two front wheels 12 and two rear wheels 14.
Riding seat 20 may be attached to frame 18, such as by means of seat post 21 slidingly mounted in tube 22. Drive mechanism 24 is coupled to one or more of the wheels 12 or 14 for driving the cycling apparatus. One or more handlebar posts 26 may be attached to a portion of frame 18. Carrier member 28 may be attached to any portion of frame 18 (e.g., to handlebar post 26) for carrying a child and/or an object (e.g., carrier member 28 may be a child seat or a shopping container). In the non-limiting preferred example, there are two handlebar posts 26 separated by a space, wherein at least a portion of the carrier member 28 is disposed in the space between the handlebar posts 26.
