The present apparatus and method relate to a brake system for motorcycles. In particular, the present apparatus and method relate to a foot brake for use with motorcycles having footboards upon which an operator may rest his/her feet while riding.
Cruiser and touring style motorcycles are increasing in popularity and the demand for comfort while riding is ever present. It is generally conceded that motorcycles having footboards provide riders with a more comfortable resting place for their feet than do conventional foot pegs. Naturally, the number of motorcycles having footboards rather than foot pegs has increased rapidly. Footboards enable riders to place their feet on a small board or platform on each side of the motorcycle while riding, thereby increasing the foot support, and consequently the comfort of the ride.
Footboards have several advantages over foot pegs, especially for long distance riding. Footboards allow the rider's foot to rest fully supported on a flat surface, rather than resting on a foot peg that provides minimal support and a localized pressure point. Those familiar with motorcycle touring will appreciate that foot pegs provide little support for the lower leg, and after long rides can often result in sore muscles in the foot and calf.
One shortcoming of traditional footboards is the accessibility of the brake. For example,
The traditional brake assembly (140) is positioned such that a brake lever (144) extends upwardly and terminates at a position nearly one-half the distance of the footboard (130) distally from the front end of the footboard. Likewise, the brake pad (148) attached to the end of the brake lever (144) is positioned several inches distally from the front end of the footboard (130).
The position of the brake lever (144) and brake pad (148) result in the rider's leg (105) being bent at the knee at an uncomfortable angle during extended travel. To alleviate some of the pressure placed on the knee in this position, riders (100) slide their feet (120) forward under the brake pad (148) as shown in
In order to move the foot (120) into the proper position for braking, the rider (100) must move the foot rearward, lift the foot, move the foot forward onto the brake pad (148) and push down, as shown in
After the brake has been applied and released, the rider must go through a reverse series of movements to return the foot (120) to the original, comfortable position located between the brake pad (148) and the foot board (130). When repeated braking is required, like in city driving, for example, the process can become both annoying and tiresome.
Consequently, there is a need for a brake actuation assembly for use with footboards that enables riders to comfortably actuate the brakes, does not cause fatigue when used frequently, and improves reaction time in emergency situations. Such a brake assembly should be simple to install and not interfere with other aspects of the motorcycle's operation.
Other solutions to this problem have been proposed, all of which required the use of a brake lever assembly independent from the footboard. These proposed solutions fail to resolve the problem of increased braking reaction times and driver fatigue due to the required lower leg, ankle, and foot movements to actuate the braking lever.
The present exemplary system and method provides a brake assembly integrated with a footboard for use on motorcycles. The present apparatus does not involve excessive movement of the lower leg, thereby decreasing the braking reaction time as compared with the prior art. The present exemplary apparatus and method also provide a more ergonomic and safe brake actuation system for motorcycles utilizing footboards.
The above advantages are realized by incorporating the brake actuation into the footboard itself. As will be explained in detail below, a motorcycle operator (a rider) can use the footboard to rest his/her foot while driving, and to actuate the brake the operator need only pivot the footboard. Such an apparatus eliminates all extraneous motion that is traditionally required of a rider using a system with a separate brake lever assembly.
According to one exemplary embodiment, the rear brake actuation takes place with the right foot. According to alternative embodiments, the present system and method is configured for use with either the right or the left foot of the rider.
A footboard of any size or shape and of varying materials is configured for use on any number of motorcycles. According to one exemplary embodiment, the footboard and braking assembly of the present apparatus and method are adapted for replacing existing brake assemblies, both those with footboards and those with foot pegs. According to one exemplary embodiment of the present system and method, a footboard is pivotably connected to a brake mechanism and when actuated causes the rear brake to be applied.
According to one exemplary embodiment, a pivot pin allows the present system and method to be universally installed on a wide variety of motorcycles. Specifically, a brake actuator configured with a first orifice to mate with the pivot pin and a second orifice to interact with a motorcycle's existing brake mechanism allows for a universal connection between the apparatus and a variety of brake mechanisms.

A brake actuator assembly is disclosed herein that provides increased ergonomic function to the driver, faster reaction time during emergency braking, and an easier braking operation. An apparatus, combining the footboard and brake lever into a single configuration includes, according to one exemplary embodiment, a footboard resting on a supporting structure capable of rotation, a supporting pin allowing rotation, and a brake actuator incorporated into the assembly. According to one exemplary embodiment, the brake actuator is compatible with braking systems commonly found on existing motorcycles. Consequently, according to one exemplary embodiment, traditional footboard and peg assemblies can be replaced by the footboard and brake assembly disclosed herein will little or no modification to the brake system itself.
In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the present apparatus and method. However, it will be apparent to one skilled in the art that the present method and system may be practiced without these specific details. Reference in the specification to “one embodiment” or “an embodiment” means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. The appearance of the phrase “in one embodiment” in various places in the specification are not necessarily all referring to the same embodiment.
Unless the context requires otherwise, throughout the specification and claims which follow, the word “comprise” and variations thereof, such as, “comprises” and “comprising” are to be construed in an open, inclusive sense, that is as “including, but not limited to.”
The following description is presented to illustrate and describe several embodiments of the present exemplary system and method; it is not intended to limit the system and method to any exact form disclosed in conjunction with the various embodiments.
As will be seen below, the present exemplary system is described in detail, including the support mechanism, pins, and actuators, according to several exemplary embodiments. Then, the method of use is contrasted to that of the prior art, delineating several advantages.
To fully understand the use and application of the present apparatus and method over traditional braking systems, an understanding of traditional footboard and brake assemblies is provided. Referring to
The platform (230) may be of various sizes and shapes. Particularly, various manufactures of footboards (250) and motorcycles may choose styles, patterns, and grip surfaces that correlate will with the overall style of the rider or motorcycle. Any of a variety of footboards (250) may be used with the present exemplary system and method. Typically, footboards (250) are secured to the motorcycle via one or more support bars (210) that are securely coupled to the frame of the motorcycle. Despite this traditional support system for footboards, the present system may be adapted for use with any number of footboards utilizing various support bar configurations described in further detail below.
Continuing with
Similar to the traditional pivot point (160) associated with a traditional brake lever (144) and brake pad (148), the pivot support actuator (350) of the present exemplary system and method is configured to actuate a braking system when rotated. Specifically, when a sufficient force is exerted on the platform (230) and the pivot support actuator (350) is rotated, the pivot support actuator, via internal connections to the existing brake system, will actuate the brake mechanism proportional with the actuating force exerted on the platform (230). As illustrated in
Referring to the traditional system illustrated in
In contrast, the present configuration of the exemplary system and method illustrated in
Turning to
According to alternative embodiments, the combined footboard and brake apparatus incorporates a footboard as an integral part of the apparatus. That is, rather than utilizing the original footboard (250), a new footboard is provided that forms an integral part of the brake actuation apparatus. According to one exemplary embodiment where the original footboard is not utilized, the present exemplary footboard configuration (
Additionally, many shapes, sizes, styles, and grip surfaces may be utilized in conjunction with the preset exemplary apparatus. According to various embodiments, the original footboard of the motorcycle can be reused. Alternatively, the apparatus may include a modified footboard as an integral part of the overall braking apparatus.
In addition, the physical position of the footboard (250) relative to the ground may be higher or lower when compared to the placement of traditional footboards. Specifically, according to one exemplary embodiment, a higher vertical position of the footboard (250) relative to the ground may be incorporated to provide increased ground clearance of the footboard (250) from the ground when cornering, thereby decreasing the likelihood of unintentional brake actuation. In fact, various modifications are possible offsetting the pivoting footboard as compared to the prior location of the footboard in any direction desired. This offers the rider the option to position the modified pivotable footboard in nearly any location.
As mentioned above, according to one exemplary embodiment, the footboard (250) portion of the present exemplary brake actuation system pivots about the pivot support actuator.
According to one exemplary embodiment of the present supporting brake actuation structure (500), the footboard support arms (510) extend from the footboard support structure (520) and provide connection to and support for a conventional footboard (250,
According to one exemplary embodiment, the support arms (510) are manufactured as an integral part of the footboard support structure (520). Alternatively, the support arms (510) may be manufactured separate and thereafter fastened to the support structure (520). Regardless, the support arms (510) and the support structure (520) provide an element of rigidity and linkage from the footboard (250,
According to one exemplary embodiment, the pivot cylinder (530) is positioned slightly in front of the midpoint of the support arms (510). According to this exemplary embodiment, the relative position of the pivot cylinder (530) prevents accidental actuation of the brake system by requiring at least a predefined amount of force to actuate the brake mechanism. According to the illustrated embodiment, the pivot cylinder (530) is free to rotate about a pivot support pin (700,
According to one exemplary embodiment, the present brake actuator (550) may be manufactured separately and then assembled to the brake actuation structure (500) as shown in
According to one exemplary embodiment, the exemplary pivot support pin (700) illustrated in
The illustrated exemplary pivot support pin (700) is configured for compatibility with existing brake systems on current motorcycles. According to one embodiment, the pivot support pin is manufactured with appropriate connections (720) according to the make and model of the motorcycle on which it is to be installed. The present exemplary embodiment shows the connection (720) including two adjacent machined angles allowing a quick fastening of the pin (700) to the motorcycle. The chamfered edge of the pin (720) allows insertion of the pin (700) while locking the pin (700) in place after insertion. Alternative configurations are foreseen and expected as necessary to accommodate the make and model of motorcycle. Variations regarding the method and manner of installing the pin (700) will depend largely upon the manufacturing of the motorcycle itself. The embodiment illustrated in
The brake assembly, including the support structure (500), is positioned relative to the other parts of the motorcycle by a boundary protrusion (710). Specifically, the footboard braking structure (500) is secured to and rests on the brake actuator support cylinder (730). According to traditional systems, the support cylinder (730) is much shorter as it only supports the brake assembly (140,
The freedom of rotation between the brake actuator (550) and support structure (500) and pivot support pin (500) may be accomplished by any acceptable means known to one skilled in the art. It may include but is in no way limited to bearings, lubricants, or other acceptable joints or combinations thereof.
While the present exemplary system has been described and illustrated as using a single specific brake assembly and corresponding supporting cylinder, the teachings of the present exemplary system and method may be modified to correlate with various motorcycle types, sizes, and configurations.
In general, the present exemplary system and method provides for an integrated footboard and braking system. Providing an apparatus functioning as both a footboard and brake actuator, both the comfort of the rider's foot and the effectiveness of the braking mechanism are enhanced. Further, the combination footboard and brake actuation member provides better reaction time when braking is required. Furthermore, the present exemplary system and method includes a number of incorporated safety features including, but in no way limited to, increased angle and positioning of the footboard and added strength to the supporting actuation cylinder. Additionally, according to several embodiments, it offers the rider the opportunity to modify the height or position of the footboard as compared to the original footboard and brake lever position.
While the present system and method has been described exclusively for use with a motorcycle having a brake actuated by a rider's right foot, adaptations for use on the left side are possible. Additionally, while the present system and method have been described for use with a motorcycle, the combination footboard and brake may also be used with three-wheelers, four-wheelers, cars, go-carts, and any other type of all-terrain vehicle or vehicle in general. The specific details may be easily adapted for incorporation into a wide variety of vehicles utilizing a foot brake. If fact, the footboard/actuator might be used to actuate and/or control alternative devices as well, including but not limited to, the clutch, the acceleration, the brakes, and other mechanically actuated devices.
After removing the initial footboard (250,
The brake actuator (550,
According to various embodiments, the footboard may be an integral part of the brake actuator support. Consequently, it would be installed simultaneously in Step 820. According to one exemplary embodiment, the footboard (250) used is the same footboard (250) that was removed in Step 800. Alternative embodiments utilize a footboard specifically designed for the apparatus. Such a footboard may be included with the assembly. Various methods to secure a footboard to the footboard support arms (510) are possible. The methods used may depend upon the make and model of footboard and/or motorcycle.
Once the combination footboard and brake apparatus is fully installed, a rider need only rotate the right foot forward to actuate the internal brake mechanism. The slight forward rotation will cause the footboard (250) to pivot about the pivot cylinder (530) causing the brake actuator (550) to rotate, thereby actuating the internal brake mechanism (Step 850).
The preceding description provides a method of securing the combination footboard and brake apparatus to a motorcycle, according to one exemplary embodiment. The steps delineated in
