1. Field of the Invention
The present invention relates to motorcycle stands, and more particularly to a rotating dirt bike stand configured to rotate into a supporting position as a dirt bike-type motorcycle or the like is pushed into the stand.
2. Background and Related Art
Some motorcycles, such as dirt bikes, do not include an attached stand such as a kick stand. While the lack of an attached stand serves to protect the rider of the dirt bike from accident or injury during riding including extreme riding (e.g. motocross, performance of tricks, and the like), the lack of an attached stand can be bothersome when the motorcycle rider wishes to dismount the motorcycle and leave the motorcycle, the rider is forced to either lay the motorcycle down on its side, lean it against a sturdy object, or utilize a stand-alone motorcycle stand. Similar problems are encountered when the motorcycle is to be worked on, as it is commonly advantageous to work on the motorcycle in an upright position.
Many stand-alone motorcycle stands are either difficult to use, are cumbersome, or include multiple moving parts that are prone to breakage during use. Such stands utilize a variety of methods to secure the motorcycle in a standing position, but with varying degrees of success. For example, stands that engage the motorcycle's front wheel may be prone to allowing too much freedom of movement to the motorcycle and thus fail to adequately secure the motorcycle. Stands that secure the rear wheel of the motorcycle are often more difficult to use, as the rider must either back into the stand or must dismount and attempt to hold the motorcycle steady while attaching or using the stand. Central lift stands that support the motorcycle by the body tend to have more moving parts and require special movements to engage the stands. Thus, existing motorcycle stands fail to adequately address the needs of the motorcycle community.
Implementation of the invention provides a motorcycle stand that is simple to use, does not require any moving parts, and that adequately supports a motorcycle in an upright position by supporting the motorcycle at the motorcycle body. The motorcycle stand is easy to use, allowing rapid and easy engagement with the stand and rapid removal from the stand without requiring unnecessary motion, as the motorcycle is simply pushed forward onto the stand and pulled backward off the stand. The forward or backward motion of the motorcycle causes rotational movement of at least a portion of the motorcycle stand, which may include some translational movement of the motorcycle stand across an underlying surface.
At least some implementations of the motorcycle stand include one or more surfaces or supports that serve to engage portions of a motorcycle as the motorcycle stand is actuated as well as when the motorcycle stand is supporting the motorcycle. The one or more surfaces or supports first engage the front wheel of the motorcycle as the motorcycle is pushed onto/over the motorcycle stand. This engagement of the front wheel causes at least a portion of the motorcycle stand to begin rotating as the front wheel continues over the motorcycle stand. As the motorcycle continues moving forward over the motorcycle stand, the one or more surfaces or supports contact or engage the body of the motorcycle behind the front wheel. This contact ensures that the motorcycle stand or portion thereof continues to rotate as the motorcycle is continued to be pushed forward.
As the motorcycle continues forward, at least a portion of the one or more surfaces or at least two of the supports rotate to be underneath the motorcycle body, thereby supporting the motorcycle in an upright position. Meanwhile, the rotation of the motorcycle stand or portion thereof causes an opposite horizontal support to engage the ground, providing a natural stopping point for the rotation of the motorcycle stand. If the motorcycle is not completely supported by the stand at this point, the motorcycle is pushed forward slightly until it is properly supported. The entire process for engaging the stand can be accomplished in one quick and smooth movement of pushing the motorcycle forward.
One implementation of the invention provides a motorcycle stand having a motorcycle engaging and supporting element for engaging and supporting a motorcycle when the motorcycle stand is in a motorcycle-supporting position in which the motorcycle engaging and supporting element is elevated above an underlying surface. The motorcycle stand includes a rotational motion driving element configured to engage a portion of a motorcycle being pushed onto the stand to cause rotation of at least a portion of the stand between a ready position in which the motorcycle engaging and supporting element is proximate the underlying surface and the motorcycle-supporting position and a rotational guiding element operatively connected to the motorcycle engaging element and the rotational motion driving element so as to guide rotation of the at least a portion of the motorcycle stand between the motorcycle-supporting position and the ready position.
The motorcycle engaging and supporting element may include a first strut and a second strut. The rotational motion driving element may be a third strut. The implementation of the motorcycle stand may further include two relationship elements connected to and maintaining the relationships between the motorcycle engaging and supporting element, the rotational motion driving element, and the rotational guiding element. Each relationship element forms a side element of the motorcycle stand, and the rotational guiding element may be formed as a part of the relationship elements.
In some implementations, each relationship element includes a side piece having a pair of opposing flat surfaces configured so that when one of the opposing flat surfaces contacts an underlying surface, the opposing flat surface is approximately parallel to the underlying surface and a curved surface forming the rotational guiding element and connecting the pair of opposing flat surfaces along a curved path. The side pieces may be side frames having a first straight portion forming one of the opposing flat surfaces, a second straight portion forming the other opposing flat surface, and a curved portion connected to the first straight portion and the second straight portion and comprising the curved surface. The curved surface and at least one of the opposing flat surfaces optionally includes a frictional surface.
In some implementations, the rotational motion driving element and the motorcycle engaging and supporting element comprise a substantially-continuous surface extending along an at least partially-curved path.
In another implementation, a rotating motorcycle stand includes a pair of side elements, each side element having a first portion configured to contact and rest upon an underlying surface when the stand is in a ready position. Each side element also includes a second portion configured to contact and rest upon the underlying surface when the stand is in a motorcycle-supporting position, wherein any surfaces of the first portion configured to contact the underlying surface in the ready position are approximately parallel to any surfaces of the second portion configured to contact the underlying surface in the motorcycle-supporting position. The side elements also have a curved portion connected to and extending between the first portion and the second portion along a curved path that permits substantially-smooth rolling of the side elements between the ready position and the motorcycle-supporting position.
The rotating motorcycle stand of this implementation includes a motorcycle-supporting element connected to and extending between the two side elements at a location proximate the first portion of the side elements, and a rotational motion driving element connected to and extending between the two side elements at a location proximate the curved portion and in between the first portion and the second portion of the side elements, thereby being elevated above the motorcycle-supporting element when the stand is in the ready position.
In another implementation, a rotating motorcycle stand includes a first side frame and a second side frame, each side frame having a first straight portion, a second straight portion approximately parallel to the first straight portion, and a curved portion connected to and extending between the first straight portion and the second straight portion along a curved, substantially-continuous path. A first strut extends between and is connected to the first straight portion of each side frame at a location distal the curved portion. A second strut extends between and is connected to the first straight portion of each side frame at a location proximal the curved portion. A third strut extends between and is connected to the curved portion of each side frame at a location intermediate the first straight portion and the second straight portion.
In some forms of this implementation, the third strut has a length longer than at least one of a length of the first strut and a length of the second strut, whereby respective planes of the first side frame and the second side frame are non-parallel to each other. Portions of the various embodiments of the motorcycle stand may be include materials such as plastic, wood, fiberglass, carbon fiber, composite materials, and metals, including tubular and solid materials, as appropriate. The various implementations of the invention are therefore described in more detail herein with respect to the accompanying Figures which are incorporated by reference.
The objects and features of the present invention will become more fully apparent from the following description and appended claims, taken in conjunction with the accompanying drawings. Understanding that these drawings depict only typical embodiments of the invention and are, therefore, not to be considered limiting of its scope, the invention will be described and explained with additional specificity and detail through the use of the accompanying drawings in which:
A description of embodiments of the present invention will now be given with reference to the Figures. It is expected that the present invention may take many other forms and shapes, hence the following disclosure is intended to be illustrative and not limiting, and the scope of the invention should be determined by reference to the appended claims.
Embodiments of the invention provide a motorcycle stand that is simple to use, does not require any moving parts, and that adequately supports a motorcycle in an upright position by supporting the motorcycle at the motorcycle body. The motorcycle stand is easy to use, allowing rapid and easy engagement with the stand and rapid removal from the stand without requiring unnecessary motion, as the motorcycle is simply pushed forward onto the stand and pulled backward off the stand. The forward or backward motion of the motorcycle causes rotational movement of at least a portion of the motorcycle stand, which may include some translational movement of the motorcycle stand across an underlying surface.
The motorcycle stand includes one or more surfaces, supports, or other structures that serve to engage portions of a motorcycle as the motorcycle stand is actuated as well as when the motorcycle stand is supporting the motorcycle. The one or more surfaces or supports first engage the front wheel of the motorcycle as the motorcycle is pushed onto/over the motorcycle stand. This engagement of the front wheel causes at least a portion of the motorcycle stand to begin rotating as the front wheel continues over the motorcycle stand. As the motorcycle continues moving forward over the motorcycle stand, the one or more surfaces or supports contact or engage the body of the motorcycle behind the front wheel. This contact ensures that the motorcycle stand or portion thereof continues to rotate as the motorcycle is continued to be pushed forward.
As the motorcycle continues forward, at least a portion of the one or more surfaces or at least two of the supports rotate to be underneath the motorcycle body, thereby supporting the motorcycle in an upright position. Meanwhile, the rotation of the motorcycle stand or portion thereof causes an opposite horizontal support to engage the ground, providing a natural stopping point for the rotation of the motorcycle stand. If the motorcycle is not completely supported by the stand at this point, the motorcycle is pushed forward slightly until it is properly supported. The entire process for engaging the stand can be accomplished in one quick and smooth movement of pushing the motorcycle forward.
Some embodiments of the a motorcycle stand have a motorcycle engaging and supporting element for engaging and supporting a motorcycle when the motorcycle stand is in a motorcycle-supporting position in which the motorcycle engaging and supporting element is elevated above an underlying surface. The motorcycle stand includes a rotational motion driving element configured to engage a portion of a motorcycle being pushed onto the stand to cause rotation of at least a portion of the stand between a ready position in which the motorcycle engaging and supporting element is proximate the underlying surface and the motorcycle-supporting position and a rotational guiding element operatively connected to the motorcycle engaging element and the rotational motion driving element so as to guide rotation of the at least a portion of the motorcycle stand between the motorcycle-supporting position and the ready position.
The motorcycle engaging and supporting element may include a first strut and a second strut. The rotational motion driving element may be a third strut. The embodiments of the motorcycle stand may further include two relationship elements connected to and maintaining the relationships between the motorcycle engaging and supporting element, the rotational motion driving element, and the rotational guiding element. Each relationship element forms a side element of the motorcycle stand, and the rotational guiding element may be formed as a part of the relationship elements.
In some embodiments, each relationship element includes a side piece having a pair of opposing flat surfaces configured so that when one of the opposing flat surfaces contacts an underlying surface, the opposing flat surface is approximately parallel to the underlying surface and a curved surface forming the rotational guiding element and connecting the pair of opposing flat surfaces along a curved path. The side pieces may be side frames having a first straight portion forming one of the opposing flat surfaces, a second straight portion forming the other opposing flat surface, and a curved portion connected to the first straight portion and the second straight portion and comprising the curved surface. The curved surface and at least one of the opposing flat surfaces optionally includes a frictional surface.
In some embodiments, the rotational motion driving element and the motorcycle engaging and supporting element comprise a substantially-continuous surface extending along an at least partially-curved path. This substantially-continuous surface may
In other embodiments, a rotating motorcycle stand includes a pair of side elements, each side element having a first portion configured to contact and rest upon an underlying surface when the stand is in a ready position. Each side element also includes a second portion configured to contact and rest upon the underlying surface when the stand is in a motorcycle-supporting position, wherein any surfaces of the first portion configured to contact the underlying surface in the ready position are approximately parallel to any surfaces of the second portion configured to contact the underlying surface in the motorcycle-supporting position. The side elements also have a curved portion connected to and extending between the first portion and the second portion along a curved path that permits substantially-smooth rolling of the side elements between the ready position and the motorcycle-supporting position.
The rotating motorcycle stand of such embodiments includes a motorcycle-supporting element connected to and extending between the two side elements at a location proximate the first portion of the side elements, and a rotational motion driving element connected to and extending between the two side elements at a location proximate the curved portion and in between the first portion and the second portion of the side elements, thereby being elevated above the motorcycle-supporting element when the stand is in the ready position.
In other embodiments, a rotating motorcycle stand includes a first side frame and a second side frame, each side frame having a first straight portion, a second straight portion approximately parallel to the first straight portion, and a curved portion connected to and extending between the first straight portion and the second straight portion along a curved, substantially-continuous path. A first strut extends between and is connected to the first straight portion of each side frame at a location distal the curved portion. A second strut extends between and is connected to the first straight portion of each side frame at a location proximal the curved portion. A third strut extends between and is connected to the curved portion of each side frame at a location intermediate the first straight portion and the second straight portion.
In some forms of such embodiments, the third strut has a length longer than at least one of a length of the first strut and a length of the second strut, whereby respective planes of the first side frame and the second side frame are non-parallel to each other.
In this regard, the side frames 12 include a first straight portion 14 and a second straight portion 16. The first straight portion 14 and the second straight portion 16 are substantially or approximately parallel in the illustrated embodiments, that is, when the first straight portion 14 is resting fully on the ground or some other underlying surface, the second straight portion 16 is substantially or approximately parallel to the ground or other underlying surface, and when the second straight portion 16 is resting fully on the ground or some other underlying surface, the first straight portion 14 is substantially or approximately parallel to the ground or other underlying surface. Although the first straight portion 14 and the second straight portion 16 are illustrated in the referenced embodiments, it is envisioned that other embodiments may include portions similar to the first straight portion 14 and the second straight portion 16 that are substantially non-parallel or that include non-parallel portions. For example, non-parallel portions may be used to provide appropriate angles to contact and support a particular type of motorcycle in the manner discussed herein. As another example, non-parallel portions may be introduced for decorative or other purposes. Thus, the first straight portion 14 and the second straight portion 16 should be considered examples of possible first portions and second portions discussed herein only, and references herein to first and second portions should not be construed as being limited to portions that are straight.
The first straight portion 14 of each side frame 12 is connected to the second straight portion 16 by a curved portion 18. The curved portion 18 extends between the first straight portion 14 and the second straight portion 16, making a curved, substantially-continuous path between the first straight portion 14 and the second straight portion 16. As the motorcycle stand 10 is used, the curved portion 18 of each side frame 12 contacts the ground as the motorcycle stand 10 is transitioned from a first position (as shown in
This transition and motion is illustrated in
The side frames 12 may include additional elements beyond the first straight portion 14, the second straight portion 16, and the curved portion 18. For example, the ends of the first straight portion 14 and the second straight portion 16 opposite the curved portion 18 may be connected to each other by a connecting portion 20. The connecting portion 20 may serve to increase the strength of the side frame 12, but otherwise does not serve a purpose in the motion/transitioning of the motorcycle stand 10; therefore, the shape/curve of the connecting portion 20 may be varied as desired, or the connecting portion 20 may be omitted, as long as any desired strength characteristics of the motorcycle stand 10 are maintained/provided by other elements.
The side frames 12 may be made of any desired material sufficiently durable and strong to provide the functionalities discussed herein, such as tubular or solid aluminum or steel or alloys thereof, many types of hollow or solid plastics, woods, other metals, fiberglass, carbon fiber, composite materials, etc. For example, in the embodiments illustrated in
As may be appreciated from the illustrated side frames 12 and the description of the various embodiments of the invention, in some embodiments, the side frames 12 may be replaced by other planar, substantially-planar, and non-planar side elements that maintain the functionality of the embodiments of the invention. For example, in one embodiments, the side frames are replaced by a solid side element, which may be made of metal or may be formed or molded from plastic or some other material or may be carved from wood, etc. The solid side element may not have spaces between portions of the side element, as the side frame 10 has spaces between the first straight portion 14 and the second straight portion 16, etc. Instead, embodiments of the solid side element include a first straight surface and a second straight surface, which surfaces are approximately or substantially parallel (or non-parallel as necessary to provide the functionality discussed herein with respect to a particular motorcycle) so that when the first straight surface is resting on the ground or some other smooth surface, the second straight surface is substantially parallel to the ground or other smooth surface, and vice-versa. The solid side element also includes a curved surface connecting the first straight surface and the second straight surface in the manner of the curved portion 18 discussed above. By way of illustration, the motorcycle stand 10 illustrated in the views of
It should be understood that any combination or modification of the solid side element and/or side frame 12 is embraced by embodiments of the invention. For example, while a solid side element is illustrated in the views of
It should also be noted that various curvatures of the curved portion 18 or curved surface discussed above may be used. For example, the curved path of the curved portion 18 illustrated in
It will also be noted that a frictional surface 24 may optionally be provided to the side frames 12 or side elements. The frictional surface 24 may be formed of any desired material and attached to the side frames 12 or side elements in any desired fashion. Illustrative materials include natural or synthetic rubber or rubber-like materials, and soft plastics, as well as abrasions or other frictional surfaces formed directly into the side frame 10 or side element, etc. The frictional surface 24 may assist in providing good non-sliding contact between the motorcycle stand 10 (particularly the side frames 12 or other side elements) and the ground. Thus, the frictional surface 24 may optionally be limited to only the curved portion 18 and the second straight portion 16 (or the corresponding first straight surface and the corresponding curved surface).
Although the first straight portion 14 and the second straight portion 16 (or the corresponding first and second straight surfaces) have been described as being substantially straight, it is emphasized that these elements need not be completely solid or straight. For example, the second straight portion 16 need not be particularly straight in many embodiments. Instead, for whatever reason, including decorative reasons, the second straight portion 16 may not be straight but may include curved portions. In some such embodiments, the second straight portion 16 has at least two contacting portions that are located and configured to contact the ground such that when both contacting portions are touching the ground or other substantially flat surface, the first straight portion 14 is substantially parallel to the ground or flat surface. Thus, in conjunction with the other possible variations discussed above, it may be understood that a very wide variety of shapes may be used for the side frames 12 or other side elements. Additionally, it should also be understood that the side frames 12 or other side elements need not necessarily be minor images or near-minor images of each other (as illustrated in
As illustrated in
This outward angling is one feature of some embodiments of the motorcycle stand 10. In other embodiments, the side frames 12 or other side elements are substantially parallel to each other. Nevertheless, the outward angling may serve several functions when present. First, the outward angling may make it easier for a motorcycle wheel to enter the motorcycle stand 10 without catching on the side frames 12 or other side elements, both as the motorcycle is pushed into/onto the motorcycle stand 10 and as the motorcycle is pushed/pulled off of/out of the motorcycle stand 10. Second, the outward angling causes the motorcycle stand 10 to have a broader base when supporting a motorcycle, inherently improving the stability of the motorcycle stand 10 and the supported motorcycle. Some users may find the aesthetics of the motorcycle stand 10 with outward angling pleasant, and other users may prefer the aesthetics of the motorcycle stand 10 with minimal to no outward angling, and embodiments may be provided with any degree of outward angling.
Although three bars or struts 26, 28, 30 have been illustrated in the embodiments shown in
The various bars, struts, or surfaces discussed above serve several functions, as will now be discussed with particular reference to
As the motorcycle 32 continues to move forward, the motorcycle stand 10 continues to rotate forward, until the front wheel 34 finishes passing over the third bar or strut 30 (or equivalent), when the first and second straight surfaces are pointing roughly upward from the ground and the curved surface is still contacting the ground (C). The motorcycle stand 10 continues rotating forward and/or remains with the first and second straight surfaces pointing roughly upward based on one or more of several principles. First, if the motorcycle 32 is moving forward with some speed, the rotational inertia imparted to the motorcycle stand 10 by the passage of the front wheel 34 will tend to continue to rotate the motorcycle stand 10. Second, the motorcycle stand 10 may be weighted or otherwise biased to remain in this position and/or to continue rotating. Third, the curved portion may be provided with a curvature or even a flattened portion that tends to continue the rotation of the motorcycle stand 10. Fourth, as the first bar or strut 26 (or other corresponding structure) is above the ground a significant amount in the rotated position, it is in a position to engage the forward-moving frame of the motorcycle 32 or some other fixed portion (e.g. motor) of the motorcycle 32 behind the front wheel 34.
As the frame, engine, etc. of the motorcycle 32 contacts the first bar or strut 26 (or other corresponding structure), the forward motion of the motorcycle 32 causes the motorcycle stand 10 to continue rotating (D). Thus, the first bar or strut 26 also aids in rotation of the motorcycle stand 10 and is another example of a rotational motion driving element. Then, as the motorcycle 32 continues moving forward and the motorcycle stand 10 continues rotating forward, the frame, engine, etc. of the motorcycle 32 begins to ride up on the first bar or strut 26 and/or the second bar or strut 28 (E), thus the first bar or strut 26 and/or the second bar or strut 28 (or equivalent) engages and begins to support the motorcycle 32.
Finally, as the second straight surface of the motorcycle stand 10 is fully contacting the ground, the first bar or strut 26 and the second bar or strut 28 (or other corresponding structures or surfaces) become horizontal to the ground, whereupon the motorcycle 32 is either resting on the first bar or strut 26 and the second bar or strut 28 or can be easily slid forward to rest upon the first bar or strut 26 and the second bar or strut 28 (F). In that regard, the frictional surface 24 (if present), may assist in keeping the motorcycle stand 10 securely in place while the motorcycle 32 slides the last bit forward, and the first bar or strut 26 and the second bar or strut 28 (or other corresponding structure or surface) may be made of a lower-friction material or may have a lower-friction motorcycle-contacting surface.
When the motorcycle is removed, the user begins pulling backward on the motorcycle 32 (F). The friction between the motorcycle 32 and the motorcycle stand 10 causes the motorcycle stand 10 to begin rotating backward (E). As the motorcycle 32 moves further backward, the motorcycle stand 10 continues to rotate backward (due to rotational inertia, etc.), and the rotation may be assisted in some embodiments by the rear portion of the front wheel 34 contacting and pushing backward on the first bar or strut 26 (or other corresponding structure). Eventually, the frame, motor, etc. of the motorcycle 32 leaves the motorcycle stand 10 (D), and the front wheel 34 enters the motorcycle stand 10, beginning to rest on the third bar or strut 30 (or corresponding structure/surface) (C).
As the motorcycle 32 continues to move backward, the front wheel pushes on the first bar or strut 26 and/or the second bar or strut 28 (or the corresponding structure or surface), continuing the backward rotation of the motorcycle stand 10 (B). Finally, the motorcycle stand 10 returns to its original position with the first straight surface contacting the ground, whereupon, backward rotation of the motorcycle stand substantially stops and the front wheel 34 of the motorcycle 32 rolls out of the motorcycle stand 10 backward.
As will be appreciated from the views of
When the motorcycle 32 is secured by the motorcycle stand 10 (as per (F) of
Indeed, the motorcycle stand 10 may also tip slightly forward or backward with the motorcycle 32, or the motorcycle stand 10 may not tip with the motorcycle 32. If the motorcycle stand 10 tips slightly with the motorcycle 32, the entire second straight surface/second straight portion 16 may not be in contact with the ground. Instead, only a portion of the second straight surface/second straight portion 16 of each lateral side of the motorcycle stand 10 will be in contact with the ground, while the wheel of the motorcycle 32 is also in contact with the ground. In this case, the two points of contact of the motorcycle stand 10 with the ground and the third point of the wheel form a stable tripod-type contact with the ground, which adequately stabilizes the motorcycle 32.
Thus, when the motorcycle 32 is being supported by the motorcycle stand 10, the motorcycle frame is typically in contact with the first bar or strut 26 and the second bar or strut 28 (or some other corresponding structure/surface, as discussed above). Commonly, no portion of the motorcycle 32 need contact any portion of the first straight portion 14 (or first straight surface, or other corresponding structure, as discussed above) of the motorcycle stand 10 while being supported by the motorcycle stand 10. Additionally, when the motorcycle 32 is being supported by the motorcycle stand 10, only a small portion of each second straight portion 16 (or corresponding structure) of the motorcycle stand 10 need contact the ground. Thus, the second straight portion 16 (or corresponding structure) need not be entirely straight and may be replaced by a curved element or a discontinuous element as desired for decorative or other reasons.
Meanwhile, when the motorcycle stand 10 is not supporting the motorcycle 32, it is held in a ready position to receive the front wheel 34 of the motorcycle 32 by the first straight portions 14 (or corresponding structure) of each side, but as this function may equally well be provided by a curved element or a discontinuous element as desired for decorative or other reasons, some embodiments may provide such features as desired for decorative or other reasons.
Finally, when the motorcycle stand 10 is being transitioned between the ready position and the supporting position, the rotation is guided by the curved portion 18 (or the curved surface or other corresponding structure as discussed above), as driven by the motorcycle wheel 34 and/or other structure of the motorcycle 32 engaging the third bar or strut 30 (or other structure or surface as discussed above) as well as the first bar or strut 26 (or other corresponding surface or structure as discussed above) and the second bar or strut 28 (or other corresponding surface or structure as discussed above). Thus, the curved portion serves as a rotational guiding element or rotational motion guiding element that guides the rotation of such embodiments of the motorcycle stand 10.
Thus, functional elements of some embodiments of the motorcycle stand 10 include 1) a motorcycle engaging and supporting element or structure or means for engaging and supporting a motorcycle when the motorcycle stand 10 is in a motorcycle-supporting position (e.g. some structure or element corresponding to the first bar or strut 26 and the second bar or strut 28); 2) a rotational motion driving structure or element or means for driving rotation of the motorcycle stand 10 between a ready position and the motorcycle-supporting position and vice-versa (e.g. some structure or element primarily corresponding to the third bar or strut 30 and potentially corresponding to one or more of the first bar or strut 26 and the second bar or strut 28); 3) a rotational guiding structure or element or means for guiding rotation of the motorcycle stand 10 between the motorcycle-supporting position and the ready position and vice-versa (e.g. some structure or element corresponding to the curved portion 18 or curved surface discussed above). Embodiments of the motorcycle stand 10 also include 4) a structure, element, or means for maintaining the relationships between the first three elements (such as the side frames 12, the side elements, etc. discussed above).
As discussed above, certain embodiments of the invention are characterized by rotation of at least a portion the motorcycle stand 10 driven by engagement of the front wheel 34 of the motorcycle 32 (and potentially other structures of the motorcycle 32) as the motorcycle 32 is pushed onto or pulled off of the motorcycle stand 10. In many such embodiments, the rotation of at least a portion of the motorcycle stand is accompanied by translational rolling of the motorcycle stand 10 across an underlying surface such as the ground. Other embodiments are envisioned where at least a portion of the motorcycle stand 10 rotates driven by engagement of the front wheel 34 of the motorcycle 32 (and potentially other structures of the motorcycle 32) and where this portion supports the motorcycle in a similar motorcycle-supporting position, but where such rotation is not accompanied by translational rolling of the entire motorcycle stand 10 across an underlying surface. Instead, the motorcycle stand 10 of such embodiments remains in an essentially fixed position, and the motorcycle 32 is pushed through this fixed position to engage the motorcycle stand 10.
Some such embodiments incorporate several parts that move/rotate in relation to each other. One such embodiment is conceptually illustrated in
Instead, the motorcycle-supporting frame 38 is slightly elevated above the underlying surface when the motorcycle stand 10 is in the ready position illustrated in
The rotational joint 40 may be provided with a frictional mechanism to prevent un-forced, un-wanted reverse rotation of the motorcycle-supporting frame 38 relative to the base frame 36 until the motorcycle body, engine, etc. engages and begins pushing forward on the first bar or strut 26 to continue the clockwise rotation of the motorcycle-supporting frame 38 relative to the base frame 36. The continued forward motion of the motorcycle 32 completes rotation of the motorcycle-supporting frame 38 until the motorcycle stand 10 is in the motorcycle-supporting position shown in
The previously-discussed embodiments rely on the transfer of energy from momentum of the motorcycle and/or from the user pushing the motorcycle into the motorcycle stand 10 to generate rotational movement of at least a portion of the motorcycle stand 10. Other embodiments are envisioned that utilize a different source of energy to generate similar rotational movement of at least a portion of the motorcycle stand 10. In some such embodiments, rotational movement of at least a portion of the motorcycle stand 10 is activated or triggered by the front wheel of a motorcycle passing through the motorcycle stand 10. After the rotational movement is triggered or otherwise activated, it may be powered/driven by energy supplied and/or stored in one or more springs, pneumatic cylinders, and/or hydraulic cylinders. In such embodiments, the rotational movement may be primarily driven by such stored or supplied energy, or it may be assisted by momentum of the motorcycle or by someone pushing the motorcycle. As with other discussed embodiments, the rotational motion of at least a portion of the motorcycle stand 10 engages and lifts/supports at least a portion of the motorcycle.
The present invention may be embodied in other specific forms without departing from its spirit or essential characteristics. The described embodiments are to be considered in all respects only as illustrative and not restrictive. The scope of the invention is, therefore, indicated by the appended claims, rather than by the foregoing description. All changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.
