说明书全文 | This application claims the benefit of U.S. Provisional Patent Application 61/860,187, filed on Jul. 30, 2013, and incorporated herein by reference. Not Applicable. This invention relates to bicycle seats, and more particularly to a stabilizing bicycle seat that provides increased power transfer from the cyclist to the bicycle. Serious bicycle athletes are concerned about using energy efficiently. For example, pedals with shoe clips allow the cyclist to add power on the upswing of the pedals to provide even more power and speed. Aerodynamic helmets and other accessories are common to reduce drag. However, heretofore no solutions exist for decreasing energy wasted by a cyclist trying to maintain a desired position on the bicycle's seat. Frequently a cyclist will find himself having slid back on the seat and then must pull himself forward, utilizing energy in the process. Likewise, around turns a cyclist frequently finds himself shifting lateral position on the seat undesirably. Therefore, there is a need for a bicycle seat attachment, replacement bicycle seat, or bicycle seat system that provides for inhibiting unwanted forward and rearward sliding of the cyclist on the seat, unwanted lateral movement of the cyclist on the seat, or a combination thereof. Such a needed invention would help the cyclist generate more power to the pedals through a more stable body-to-seat interface. Such a needed device would be relatively simple to install either on a new or used bicycle, and would be intuitive to use. Further, such a needed device would be relatively inexpensive to manufacture and lightweight. The present invention accomplishes these objectives. The present device is a bicycle seat attachment for use on a bicycle seat of a bicycle by a person. Some embodiments take the form of being integrated into a replacement seat of the bicycle. Further, some embodiments take the form of either a bicycle seat attachment or a replacement seat, either used in combination with a cooperative lower garment worn by the rider. In a first embodiment, a base has a forward end adapted to buttress the posterior of the person. A clamping mechanism is fixed with the base and engages the bicycle seat around a rear end thereof. The clamping mechanism secures the base, preferably at a lower side thereof, between a top side of the seat and a bottom side of the seat. As such, with the clamping mechanism engaged with the seat, the person's posterior upon contacting the forward end of the base is prevented from further backward movement relative to the seat. In a second embodiment of the invention, the bicycle seat attachment includes the base, a forward end, a rearward end, and a downwardly-projecting loop adapted to receive therein a forward thin portion of the bicycle seat. The rearward end terminates in an upwardly-raised flange adapted to buttress the posterior of the person. The forward end terminates in a resilient upwardly-projecting tongue. The base thereby forms a saddle for inhibiting forward and rearward motion in the seat by the person. Preferably the upwardly-projecting tongue is malleable and, as such, selectively angularly adjustable. Further, preferably the upper side of the base includes a plurality of laterally traversing ridges for inhibiting through friction backward and forward movement of the person while seated thereon. In such an embodiment, the clamping mechanism is fixed to the rearward end of the base and the loop of the base. The clamping mechanism is adapted to retain the base onto the bicycle seat by pulling the loop of the base rearward towards the rearward end of the base through a length-adjustable strap. Preferably the clamping mechanism includes a rigid Y-shaped connector adapted to straddle a bicycle seat post while engaging the loop of the base at a forward end. The Y-shaped connector further provides a strap loop at a rear end thereof for engaging the strap therethrough. In a third embodiment of the invention, a bottom side of a replacement seat is adapted for selective attachment to a bicycle seat post of the bicycle, as is known in the art. A top side of the seat is adapted for receiving the posterior of the person, and a rear side has at least one of the upwardly-projecting flanges adapted to buttress the posterior of the person. A forward side of the seat includes a central raised protrusion projecting upward and adapted to inhibit forward motion of the person while seated thereon. The protrusion is preferably made from a deformable, malleable material. The top side of the seat may further include a high-friction surface treatment, so that sliding movement thereon by the person is inhibited. A forth embodiment of the invention includes a central longitudinal groove formed between a left half and a right half of the top side of the seat. Both sides of the seat are mutually resiliently deformable either towards or away from each other laterally, such that the person is inhibited from both forward or rearward movement while seated yet not inhibited in lateral movements from side to side. A fifth embodiment of the invention is a bicycle seat system, comprising the bicycle seat that includes on the top side thereof a plurality of the laterally traversing ridges, and a lower garment worn by the person that has a posterior seat engagement portion that includes a plurality of grooves, each of which are adapted to receive one of the laterally traversing ridges of the seat. As such, when the person is seated on the seat while wearing the lower garment, the upwardly-extending ridges of the seat engage the grooves of the garment to inhibit forward and backward motion of the person while seated. The person, when elevated above the seat such as by standing on bicycle pedals, is free to adjust his position forward or backward with respect to the seat before sitting again on the seat at a more desired position. In such an embodiment, the ridges of the seat may be sloped in a rearward direction and the grooves may be sloped in a forward direction, such that the bicycle seat system forms a ratchet mechanism between the seat and the lower garment. As such movement of the person forward is achievable by sliding forward, while rearward movement is prevented unless the person disengages the ridges from the grooves, such as by standing. In one embodiment, the top side of the seat includes a left series of ridges and a right series of ridges, and the lower garment includes a left series of grooves and a right series of grooves. The left series of ridges and grooves are angled in a first direction, and the right series of ridges and grooves are angled in a second direction. As such, when the left series of ridges are engaged with the left series of grooves, and the when the right series of ridges are engaged with the right series of grooves, forward, rearward and lateral movement of the person is inhibited, unless the person disengages the ridges, from the grooves, such as by standing. Such an embodiment may be incorporated into a base for use with an existing bicycle seat, and fastened to the seat with straps, such as elastic or non-elastic straps, or may be integrally formed in a replacement bicycle seat. In a seventh embodiment, the top side of the bicycle seat includes the longitudinal groove and the lower garment includes a downwardly-projecting fin from the posterior seat engagement portion. The fin may be curved from front to back, whereby when engaged with the longitudinal groove the person may adjust his angular position from forward to rearward in the seat while still being inhibited from lateral motion from side to side. As such, when the person is seated on the seat while wearing the lower garment, the fin of the garment engages the longitudinal groove of the seat to inhibit lateral motion of the person while seated. In such an embodiment, the top side of the seat may further include the plurality of laterally-traversing ridges on both sides of the longitudinal groove, and the posterior seat engagement portion may further include a plurality of the grooves that are each adapted to receive one of the laterally traversing ridges of the seat. As such, when the person is seated on the seat while wearing the lower garment, the upwardly-extending ridges of the seat engage the grooves of the garment to inhibit forward and backward motion of the person while seated. The person when elevated above the seat is free to adjust his position forward or backward with respect to the seat before sitting again on the seat, the fin projecting away from the garment further than the ridges project away from the seat, so as to prevent lateral movement of the person with respect to the seat while still allowing the person to adjust his position forward or backward. In an eighth embodiment of the invention, the posterior seat engagement portion of the lower garment includes a downwardly-projecting platform adapted for engagement with the longitudinal groove of the seat. A bottom side of the longitudinal groove may further include the plurality of laterally-traversing ridges, and the platform of the lower garment may further include the plurality of grooves each adapted to receive one of the laterally traversing ridges of the longitudinal groove. As such, when the person is seated on the seat while wearing the lower garment, the upwardly-extending ridges of longitudinal groove engage the grooves of the platform to inhibit forward and backward motion of the person while seated. When the person elevates his posterior slightly off of the seat, he is free to adjust his position forward or backward with respect to the seat before sitting again on the seat in a more preferred position. In a ninth embodiment of the bicycle seat system, the longitudinal groove of the seat includes an upwardly-projecting longitudinal catch that has both a forward undercut and a rearward undercut. The posterior seat engagement portion of the lower garment projects downwardly and includes a groove therein that is adapted for engaging the longitudinal catch of the seat. The groove includes a forward undercut and a rearward undercut, each that cooperative with the forward and rearward undercuts, respectively, of the longitudinal catch to prevent upward movement of the person off of the seat when so engaged. The present invention is a bicycle seat attachment, replacement bicycle seat, or bicycle seat system that provides for inhibiting unwanted forward and rearward sliding of the cyclist on the seat, unwanted lateral movement of the cyclist on the seat, or a combination thereof. The present system allows the cyclist to generate more power to the pedals through a more stable body-to-seat interface. The present invention is relatively simple to install either on a new or used bicycle, and is intuitive to use. Further, the present invention is relatively inexpensive to manufacture and lightweight. Other features and advantages of the present invention will become apparent from the following more detailed description, taken in conjunction with the accompanying drawings, which illustrate, by way of example, the principles of the invention. Illustrative embodiments of the invention are described below. The following explanation provides specific details for a thorough understanding of and enabling description for these embodiments. One skilled in the art will understand that the invention may be practiced without such details. In other instances, well-known structures and functions have not been shown or described in detail to avoid unnecessarily obscuring the description of the embodiments. Unless the context clearly requires otherwise, throughout the description and the claims, the words “comprise,” “comprising,” and the like are to be construed in an inclusive sense as opposed to an exclusive or exhaustive sense; that is to say, in the sense of “including, but not limited to.” Words using the singular or plural number also include the plural or singular number respectively. Additionally, the words “herein,” “above,” “below” and words of similar import, when used in this application, shall refer to this application as a whole and not to any particular portions of this application. When the claims use the word “or” in reference to a list of two or more items, that word covers all of the following interpretations of the word: any of the items in the list, all of the items in the list and any combination of the items in the list. When the word “each” is used to refer to an element that was previously introduced as being at least one in number, the word “each” does not necessarily imply a plurality of the elements, but can also mean a singular element. The present invention can take the form of a bicycle seat attachment or accessory, a replacement seat for either a new or used bicycle, or a bicycle seat system comprising a seat configured to cooperate in a variety of ways with a lower garment worn by the cyclist. The clamping mechanism 50 secures the base 40, preferably at a lower side 41 thereof, between a top side 27 of the seat 20 and a bottom side 23 of the seat 20. The clamping mechanism 50 may include a threaded clamp bolt (not shown), or the like, to secure the base 40 to the seat 20. The clamping mechanism 50 may be resiliently fixed with the base 40, such as with a spring means 70, such that the base 40 may be moved forward and backward with respect to the seat 20 while the clamping mechanism retains the bicycle seat attachment 10 to the bicycle seat 20 and urges the base 40 towards a resiliently-neutral position with respect to the seat 20. As such, with the clamping mechanism 50 engaged with the seat 20, the person's posterior 32 upon contacting the forward end 48 of the base 40 is prevented from further backward movement relative to the seat 20. In such an embodiment, the clamping mechanism 50 is fixed to the rearward end 42 of the base 40 and the loop 80 of the base 40. The clamping mechanism 50 is adapted to retain the base 40 onto the bicycle seat 40 by pulling the loop 80 of the base 40 rearward towards the rearward end 42 of the base 40 through a length-adjustable strap 120. Preferably the clamping mechanism 50 includes a rigid Y-shaped connector 140 adapted to straddle a bicycle seat post 21 while engaging the loop 80 of the base 40 at a forward end 148. The Y-shaped connector 140 further provides a strap loop 141 at a rear end 142 thereof for engaging the strap 120 therethrough. A lower garment 200 worn by the person 20 has a posterior seat engagement portion 210 that includes a plurality of grooves 220, each of which are adapted to receive one of the laterally traversing ridges 130 of the seat 11. As such, when the person is seated on the seat 11 while wearing the lower garment 200, the upwardly-extending ridges 130 of the seat 11 engage the grooves 220 of the garment 200 to inhibit forward and backward motion of the person 20 while seated. The person 20, when elevated above the seat 11 such as by standing on pedals (not shown), is free to adjust his position forward or backward with respect to the seat 11 before sitting again on the seat 11 at a more desired position. In such an embodiment, the ridges 130 of the seat 11 may be sloped in a rearward direction and the grooves 220 may be sloped in a forward direction, such that the bicycle seat system 12 forms a ratchet mechanism 230 between the seat 11 and the lower garment 200. As such movement of the person 20 forward is achievable by sliding forward, while rearward movement is prevented unless the person 20 disengages the ridges 130 from the grooves 220, such as by standing. Alternately, the ridges 130 of the seat 11 may be sloped in a forward direction and the grooves 220 may be sloped in a rearward direction, such that the bicycle seat system 12 forms an oppositely-directed ratchet mechanism 230 between the seat 11 and the lower garment 200. As such movement of the person 20 rearward is achievable by sliding rearward, while forward movement is prevented unless the person 20 disengages the ridges 130 from the grooves 220, such as by standing. In one embodiment (not shown), some of the ridges 130 are sloped one way and the rest are sloped the other way, such that both forward and backward movement is inhibited unless the person 20 stands to reposition himself on the seat 11. In one embodiment, illustrated in In a seventh embodiment, illustrated in In such an embodiment, the top side 118 of the seat 11 may further include the plurality of laterally-traversing ridges 130 on both sides of the longitudinal groove 160, and the posterior seat engagement portion 210 may further include a plurality of the grooves 220 that are each adapted to receive one of the laterally traversing ridges 130 of the seat 11. As such, when the person 20 is seated on the seat 11 while wearing the lower garment 200, the upwardly-extending ridges 130 of the seat 11 engage the grooves 220 of the garment 200 to inhibit forward and backward motion of the person 30 while seated. The person 30 when elevated above the seat 118 is free to adjust his position forward or backward with respect to the seat 11 before sitting again on the seat 11, the fin 270 projecting away from the garment 200 further than the ridges 130 project away from the seat 118, so as to prevent lateral movement of the person 30 with respect to the seat 11 while still allowing the person to adjust his position forward or backward before sitting down again on the seat 11 in a more preferred position.
