This invention relates generally to bicycles, and more specifically to passive control of steering mechanisms.
Bicycles are inherently unstable when parked, especially touring bikes loaded with extra equipment and supplies. When parked, bicycles have a tendency to roll, or the wheel has a tendency to turn, and the bike falls over. The present invention aims to remedy the problem by holding the front wheel straight, preventing the wheel from turning and helping to keep the bike upright. This is useful both when the bike is parked in a rack or against a support. The present invention can also be used when the bicycle is being hand-driven by a dismounted user, because the front wheel held straight allows the user to better steer and support the bicycle without wobble.
This invention relates generally to bicycles, and more specifically to passive control of steering mechanisms.
The invention is comprised essentially of a clamp, a lever, and a receiver. In some embodiments the clamp may serve to couple the lever with a steer tube of a bicycle. In some embodiments, the clamp and the receiver may each be contractible, allowing a user to secure them about multiple sizes of bicycles.
A device for preventing the front wheel of a bicycle from turning, comprising a clamp, a lever, and a receiver. The clamp is configured to be removably coupled with the steer tube of a bicycle, and is adjustable to fit many sizes of bikes. The adjustable clamp is configured to be secured tightly around the steer tube to prevent rotation of the front wheel of the bicycle and to prevent rotation of the clamp around the steer tube. The lever is coupled with the clamp and is rotatable from vertical, through horizontal, to the proper angle to meet the receiver, which is disposed on a cross bar or down tube of a bicycle. The lever includes a knob and the receiver is configured to receive and slightly contract around the knob, temporarily coupling the steer tube and the cross bar or down tube, locking the wheel in its position when the lever is engaged.
In some embodiments, the lever may be hingeably coupled with the clamp, such that the lever can be moved from vertical, through horizontal, and to the proper angle to couple with the receiver, which will, in preferred embodiments, be configured to be coupleable with a top tube, cross bar, or down tube of a bicycle. The hinge coupling the lever with the clamp may be freely rotating, or it may include one or more mechanisms for returning the lever to a substantially vertical position when the knob of the lever is released from the grip of the receiver. These mechanisms may include springs such as torsion springs, clock springs, or compression springs. One would understand that many methods of returning an object to a beginning position might be employed without altering the function of the invention.
In some embodiments, the knob of the lever may be substantially round, and it may be configured to fit snugly within the grip of the receiver. The grip of the receiver may be configured to close slightly around the knob after the knob is received, applying a compressive force to hold the knob in place. The grip may further include high friction materials to help hold the knob in place.
In some embodiments, the receiver portion may couple with a bicycle down tube, cross bar, or top tube via a strap. The strap may be substantially rigid and may include a contractible fastener to allow the strap to be snugly secured around the tube to prevent slipping. The inner perimeter of the strap may further include high friction material to prevent rotation and slipping of the receiver. In other embodiments, the strap may be substantially flexible, and may be configured to stretch around the tube, holding itself in place through friction and compressive force.
In some embodiments, the receiver portion may be a two-part clamshell style clamp, wherein coupling the receiver with a tube comprises disposing the upper portion about the upper portion of the tube and the lower portion about the lower portion of the tube, then coupling the upper portion and the lower portion using fasteners disposed on one or both sides of the receiver.
In other embodiments, the receiver portion may be configured to be coupled to the tube with a bolt and nut fastener, wherein the nut may be permanently disposed on the bicycle tube and wherein the receiver may be configured to sit over the nut. The receiver may be further configured to receive the bolt through the top of the receiver, the bolt then being coupled with the nut and securing the receiver to the tube.

Steer tube clamp 101 couples with lever 201 at the end of the clamp distal to the gap and fastener 103. The clamp 101 may include a spacer area 106 that allows the lever 201 to sit farther from the receiver portion 102, giving the lever a longer horizontal reach profile. In alternative embodiments, the lever 201 may be longer and may couple with the receiver portion 102 without a spacer area 106 or with a substantially smaller spacer area. A rod, such as a bolt, or a plastic or metal rod, 105 may be disposed through clamp apertures 104 and lever apertures 202. This provides a hinge type movement for lever 201 around rod 105, allowing the lever to move from vertical through horizontal into the receiver 301, and back. In some embodiments, lever 201 may include a torsion spring 203 disposed near or around the rod 105, the torsion spring configured to bring the lever back into a vertical position when it is released from receiver 301. Lever 201 may further include a stopper 204, placed near the coupling with clamp 101, configured to slow the impact of the lever against the clamp and prevent damage to the clamp, the lever, the bike, or a user, as well as limiting or eliminating vibrations between the clamp and the lever. Stopper 204 may further be configured to provide a frictional contact between the surface of the clamp 101 and the lever 201, which may help prevent the lever from moving downward while the steer stopper is disengaged. As such, the stopper 204 may be comprised of substantially softer, more flexible materials with a high coefficient of friction, such as rubber or silicon.
In some embodiments, lever 201 may be a substantially solid length of plastic or metal, and may include knob 205 at the end distal to the clamp 101. In other embodiments, lever 201 may be substantially hollow, as depicted in
Knob 205 is configured to be received by receiver 301 when the lever 201 is moved from the vertical disengaged position to the engaged position, which may be at or lower than horizontal. Knob 205 may be removably coupled with lever 201, such that the knob can be replaced if damaged or worn. In other embodiments, knob 205 and lever 201 may be formed as a single unit, preventing the knob from unintentionally coming loose and compromising the performance of the steer stopper. In some embodiments, knob 205 may be comprised of the same material as lever 201. In other embodiments, knob 205 may be comprised of a different material, such as a material with a higher grip coefficient, or it may include a coating or layer of a high friction material, which would be beneficial in keeping it in the engaged position by increasing the grip between the knob and receiver 301.
In some embodiments, receiver 301 may be configured to receive knob 205 within the snap portion 304. Snap portion 304 may include an inner perimeter 305, configured to allow the knob 205 to snap into the snap portion 304 and exerting a grip force through at least one of compression, wherein the perimeter 305 is substantially the same size as or slightly smaller than the knob 205 when disengaged, or friction, wherein the perimeter is coated with a high friction material such as rubber or silicon, or both. In preferred embodiments, snap portion 304 may be substantially rigid, but flexible enough to allow knob 205 to be received and removed from the snap, while still holding the knob firmly in place.
In some embodiments, snap portion 304 is coupled with a strap portion 302. Strap portion 302 may be configured to be disposed around one of the top tube, also known as a cross bar, or the down tube of a bicycle. In other embodiments, strap 302 may be substantially flexible, comprised of a material such as rubber or silicone, and configured to conform to the circumference of the bicycle tube. This allows the steer stopper to be used with many sizes and even alternative shapes of bicycle tubes. In some embodiments, strap 302 may be substantially rigid, configured to fit snugly against a particular size tube, and comprised of a substantially hard or rigid material such as metal or plastic, particularly ABS plastic. In further embodiments, the inner perimeter of strap 302 may include a high friction material, such as rubber or silicone, to prevent the strap from rotating around the bicycle tube. The strap 302 may be then held firmly in place with a fastener 303. Fastener 303 may be comprised of many types of fasteners, and in preferred embodiments it may be a screw and lock nut, which provides a secure fastening of receiver 301 around the tube and helps to prevent rotation of the receiver.
While particular aspects of the present subject matter described herein have been shown and described, it will be apparent to those skilled in the art that, based upon the teachings herein, changes and modifications may be made without departing from the subject matter described herein and its broader aspects and, therefore, the appended claims are to encompass within their scope all such changes and modifications as are within the true spirit and scope of this subject matter described herein. Furthermore, it is to be understood that the invention is defined by the appended claims. It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.).
While preferred and alternative embodiments of the invention have been illustrated and described, as noted above, many changes can be made without departing from the spirit and scope of the invention. Accordingly, the scope of the invention is not limited by the disclosure of these preferred and alternate embodiments. Instead, the invention should be determined entirely by reference to the claims that follow.
