Description

VERSATILE VELOCIPEDE

Field of the Invention

[01] This invention relates to the exercise industry and, in particular, to a velocipede that can be adjusted to suit multiple riders and uses.

Background of the Invention

[02] Bicycles have always been an important recreational device. In recent years, their appeal has increased with their use for exercise and commuting.

[03] Urban bicyclists who commute to work or school are often confronted with unique problems, such as limited bicycle parking areas and theft. Moreover, it is inconvenient to deliver bicycles to rural areas and parks for use as sports/exercise equipment. As a result, bicycle manufacturers have developed bicycles which can be folded, so they may be carried and transported more easily.

[04] Many types of folding bicycles have been developed and some have been accepted as especially well suited for commuting. These folding bicycles can be folded to minimize their volume. This allows a commuter to take them to the office or school to avoid theft. For exercise enthusiasts, these folded bicycles can be easily taken with a car or on a public transport to facilitate riding anywhere.

[05] A growing need has also arisen for a more versatile recreational device, that lends itself to being more adjustable in terms of seat positioning, as well as being amenable to different modes of riding the device.

[06] There is a need for a bicycle and other velocipedes that are versatile in terms of their amenability to multiple uses and users, and in addition, can be folded into a compact package regardless of its configuration.

Summary of the Invention

[07] In some embodiments, this invention provides a velocipede, such as a bicycle, that is versatile and can be adjustable in terms of its suitability for multiple users and uses. In some embodiments, the invention provides a velocipede which can be readily folded into a compact package regardless of its configuration.

[08] In some embodiments, the invention provides a versatile velocipede comprising:

Detailed Description of the Invention

[25] In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the invention. However, it will be understood by those skilled in the art that the present invention may be practiced without these specific details. In other instances, well-known methods, procedures, and components have not been described in detail so as not to obscure the present invention.

[26] While the discussion herein is with respect to bicycles, it should be appreciated that the invention pertains to any type of velocipede with any number of wheels. Most commonly, the invention will be utilized in a two-wheel bicycle, but the invention may also be utilized in tricycles and other configurations.

[27] In some embodiments, the invention provides a versatile velocipede comprising: • at least one front and rear wheel assembly;

• a handlebar apparatus;

• a mounting assembly;

• a first support to which said handlebar apparatus is affixed at a first terminus and to which said at least one front wheel assembly is mounted at said second terminus

• a second support, to which said mounting assembly is affixed via an adjustable mount, wherein said second support is movably connected to said first support at a terminus of said second support;

[28] -whereby when deployed, said folding velocipede is adjustable in terms of the raising and lowering of the mounting and relative positioning of said mounting along a length of said second support.

[29] In some embodiments, the invention provides a versatile velocipede having front and rear wheels, a handlebar and a mounting assembly. In some embodiments, such a mounting assembly may contain any structure that allows the user to make use of the velocipede comfortably, whether by sitting on a seat, which is one envisioned mounting assembly, or by standing on appropriate feet rests, which is another envisioned mounting assembly.

[30] A first support has a first terminus to which the handlebar is affixed and a second terminus to which the front wheel is mounted. On a second support, the seat is affixed via an adjustable mount. The second support is movably connected to the first support at a terminus of the second support. On a third support the rear wheel is mounted. This third support is also movably connected to the first support at a terminus of the third support. A sliding connector connects the second and third supports such that the second support crosses or is contained within the third support, whereby, when deployed, the second support is located apically to the third support. When deployed, this versatile velocipede is adjustable in terms of the raising and lowering of the mounting assembly, e.g. a seat and relative positioning of such seat along a length of the second support.

[31] The term "versatile velocipede" as used herein is to be understood to refer to any ride- on vehicle, which is characterized by a structure as herein defined. The velocipede may be a bicycle, tricycle, scooter, or any other appropriate ride-on vehicular means, as will be appreciated by the skilled artisan. A popular velocipede is the bicycle, and examples are provided herein describing an envisioned bicycle for ease of further understanding the invention. It is to be understood, however, that reference to the term "bicycle" herein will be understood to refer to any appropriate velocipede, and the term bicycle should not be interpreted as excluding other velocipede forms, but rather serve as an example of the type of vehicle envisioned, which could readily be converted to other means without deviating from the description provided herein.

[32] The velocipedes of this invention may also be readily folded into a collapsed geometry.

[33] Figure 1 depicts an embodiment of a velocipede of this invention. According to this aspect, a versatile velocipede, in this case, a folding bicycle 10 as shown will have a head tube 12, also referred to herein as the first support. The stem 20 of the handle bars 22 fits into the open top end of the head tube, and is secured in any know manner. If desired, the stem may have a telescoping extension, so that the handle bars may be raised and lowered to fit riders of different sizes.

[34] On the lower end of the head tube, as is known in the industry, a fork 14 is formed. At the distal end of the fork a front hub 16 is placed. The front tire 18 is mounted on the front hub in known fashion.

[35] In conventional velocipedes such as bicycles, a top (or cross) bar extends essentially horizontally from the head tube, and intersects with a vertically oriented mounting tube. The mounting post then fits into a lug at the intersection of the two bars.

[36] The herein versatile velocipede has no top (or cross) bar as may be found in conventional bicycles.

[37] In particular, as will be hereinafter explained, the versatile velocipede has a type of X- shaped frame wherein the ends of the two bars pivot about the first support or head tube. The two bars are themselves connected together by a sliding connector, which in some embodiments, is like a sleeve. According to one embodiment, there are two pivot points on the first support or head tube.

[38] It should be understood that reference to the term "pivot points" does not preclude sliding, fixable points, as well. It is not, therefore, necessarily the case that such pivot points may not be further adjusted along the vertical axis of the support to which they are connected.

[39] The mounting bar can pivot about the lower pivot (or axle) and the rear bar can pivot about the upper pivot (or axle). These two bars will have a lockable movable slide that connects them together. [40] According to one embodiment (Figures 1, 2, 5 and 7), the herein versatile velocipede has a mounting bar 24 that connects directly to the head tube. In particular, in a lower section of the head tube 12 (or upper end of the fork 14), a through opening is made and an axle 26 is mounted. The end 30 of the mounting bar 24 is fit into a channel in the head tube, and the axle 26 passes through an opening in the end 30 of the mounting bar. In this manner, the mounting bar can pivot or rotate about the axle 26. In order to hold the axle in place, acorn nuts 32 may be used to cover the ends of the axle.

[41] On the opposite end of the mounting bar 24, a mounting lug 34 is mounted. A convention saddle 38 is fitted into the lug and held securely, as is know in the industry. To accommodate different size riders, the mounting lug may be mounted on a lockable slide mechanism 36. The saddle, lug and slide mechanism may together be referred to as the mounting assembly, in some embodiments. Additional elements may be further incorporated within the mounting assembly, as will be appreciated by the skilled artisan. In this way the saddle or mounting may be moved to any point along the length of the mounting bar. Further, the saddle may be mounted on an extendible shaft (as known in the industry) to permit further height adjustment for riders of different sizes.

[42] Above the first axle 26, the head tube 12 has a second opening for a second axle 42. In like fashion, a first end of a rear bar 40 is pivotally connected to the second axle, just as the mounting bar is connected to the first axle.

[43] On the opposite end of the rear tube, a rear wheel axle 44 is secured. The rear wheel 46 is mounted on its sprocket as know in the trade.

[44] A slide mechanism 48 connects the two bars together, and in some embodiments, permits a folding action.

[45] According to this aspect, and representing one embodiment, a seat slide 66 is provided on the mounting bar 24 and a rear slide 68 is provided on the rear bar 40. These two slides have similar constructions and, therefore, only the construction of the mounting slide will be described. It will be appreciated that the rear slide is made in the same manner.

[46] According to this aspect, and representing one embodiment, on one of the slides, two opposing ears 70 are formed. Each may have a through opening, and these openings are may be in alignment. According to this aspect, and representing one embodiment, the other slide has a tubular shaft 72. When assembled, According to this aspect, and representing one embodiment, the tubular shaft fits between the ears and the openings are in alignment. According to this aspect, and representing one embodiment, an axle 50 is fitted into the openings, thereby permitting the slides to pivot or rotate with respect to each other. [47] In some embodiments, and as depicted in Figures 2, 3 and 4, the mounting bar 24 may be made of opposing rails 74, defining a seat along which the mounting slide 66 may move. These rails may be made into an integral bar with through openings 76 in both the top (Figure 3) and bottom (Figure 4) surfaces. In some embodiments, the rear bar 40 is made in the same manner.

[48] Any known locking means may be used to fix the positioning of the elements of the velocipede, as will be appreciated by the skilled artisan. In one embodiment, the Drawings and description herein serve as guidance for such locking mechanisms, however, such description is not to be construed as in any way limiting the invention.

[49] In some embodiments, on each of the slides (66 and 68), a lever handle 78 may pivotally mounted on an axle 88 being removably engageable with a locking base 80. In some embodiments, extending from the bottom of the locking base are a plurality of engagement rods 82. In some embodiments, there are five engagement rods, and indeed any appropriate number may be used. In some embodiments, these rods are moveable into and out from openings 76 in the mounting bar 24. In some embodiments, each rod is fitted with a spring 84.

[50] In some embodiments, in an open or unlocked position (Figure 10), the lever handle 78 is up and does not engage the locking base 80. There is thus no force or pressure exerted on the locking base and engagement rods. By means of the force generated by the locking rods 82, the rods are forced upwards and do not engage the openings 76. In this unlocked position, the mounting slide 66 may move along the length of the mounting bar 24.

[51] The locked position of an embodied mechanism may be as shown in Figure 11. Here, the lever handle 78 is pushed down, thereby causing the undersurface 86 of the lever handle to bear against the locking base 80. This force overcomes the force of the springs and moves the engagement rods 82 into the openings 76 with which they are aligned. The engagement of the rods in the openings locks the slide in place and prevents movement.

[52] According to this aspect, and representing one embodiment, to unlock the mechanism, the lever handle, according to this aspect, may be lifted and thus pivoted upward away from the bar. This movement causes the engagement rods to move out from the openings and thereby allows freedom of movement of the slide along the bar.

[53] According to this aspect, and representing one embodiment, as the bars have multiple openings along their length, the slides may be locked at any point along the rods. Depending on the position of the slide will depend the orientation of the bars with respect to each other, and the resulting shape or configuration of the velocipede. [54] It may be appreciated that any other suitable releasable locking mechanism may be used for the bar slides. The one illustrated herein is just one example.

[55] Hence, one embodiment of the basic construction of the herein disclosed folding bicycle includes: a head tube on which the front tire is mounted, a mounting bar on which the saddle is mounted and the mounting bar being pivotally mounted on the head tube, and a rear bar on which the rear wheel is mounted and the rear bar also being pivotally mounted on the head tube. To facilitate the folding action, the slides are unlocked and thereby permit the bar to move relative to each other.

[56] In one embodiment, such versatile velocipedes may be folded for easy transport or storage. According to this aspect, and in one embodiment, to fold the bicycle, the sliding sleeves may permit the mounting bar to move along the length of the rear bar (and visa versa). Due to the pivoting action, the mounting bar pivots "up," so it is somewhat parallel to the head bar and the rear bar pivots "down," to a somewhat similar position. This pivoting motion is permitted due to the slides that allow the bars to move relative to each other while the velocipede is folded.

[57] The herein disclosed versatile velocipedes may be configured with or without a pedal mechanism. When a pedal mechanism is used, it may operate like a unicycle, bicycle or tricycle, etc. Without the pedal mechanism it can work like a scooter, and the user's feet move along the ground to propel the device. It is also envisioned that a mini-motor may be attached providing for a motorized version of the same.

[58] Referring to other embodiments as depicted in Figures 5 and 6, as is known in the industry, a sprocket can be mounted on the second or third support. A chain support bar 52 may be connected as well. In known fashion, a bicycle chain 56 is secured. Rotation of the chain causes rotation of the rear wheel, as it known in the industry. A derailleur may be provided to permit changing gears.

[59] According to this aspect, and representing one embodiment, at the other inner end of the chain support bar 52, a crank axle 58 is installed. As known in the trade the crank axle terminates with cranks 60 on either side. Pedals 62 are fitted on the ends of the cranks to facilitate pedaling. In known manner, the rider positions his feet on the pedals. Using a pedaling motion, the crank axle is rotated, thereby causing rotation of the chain ring and thus the chain.

[60] An alternate embodiment is shown in Figure 7. The key difference is that the angles are different; otherwise the construction of the head bar, mounting tube and rear tube is the same. By altering the angles and the placement of the axles and pivots, the functional shape of the bicycle can be changed.

[61] Cables for brakes and gear derailleurs pass along the various bars may be incorporated, as is done on conventional bicycles.

[62] As shown in Figure 7, one embodiment can be a mini bike with small wheels. Such a bicycle is useful for commuting and can be folded to a small size to facilitate carrying. It will be appreciated, however, that more conventionally sized bicycles, which can be folded according to the principles of this invention are envisioned, as well.

[63] Alternate configurations are shown in Figures 8 and 9. In particular, the embodiment of Figure 8 is a variant of Figure 1. Whereas in Figure 1, there is only one rear wheel, Figure 8 shows a tricycle type configuration with two rear wheels. The embodiment of Figure 9 is a type of scooter where the user is in a sitting position.

[64] Due to the sliding action between the mounting and rear bars, many different configurations can be created. One embodied feature is that the mounting and rear bars each pivot on axles located on the head tube and also pivot relative to each other due to the slide mechanisms. This creates a X-shaped frame which can then be folded.

[65] Other embodied configurations are shown in Figure 12, which embodied velocipede is similar to Figure 8, but showing an alternate embodiment of the rear assembly. One embodied wheel assembly is adjustable such that when said wheel assembly contains at least two wheels, said wheels may be movably oriented with respect to each other. The wheel assembly 90 may, in some embodiments, contain two movably connected supports 92 and 94, which may be brought closer and further apart, as depicted in Figures 12B and 12C, respectively.

[66] The invention also contemplates the incorporation of a second handle assembly, which may be fixedly or removably mounted on said second support. Figures 12D and 12E show a second handle assembly 96, which may be attached to the second support. In some aspects, according to one aspect, the second support may contain an internal adaptation, such that when said second handle assembly is mounted, such second handle assembly may be so configured as to provide for steering the front wheel of the velocipede.

[67] In some embodiments, a child safety seat may be mounted on the second support, for example, as positioned in front of or behind the mounting assembly, to allow for more than one rider on the velocipede.
