Description:
BACKGROUND OF THE INVENTION
[0001] The rising use of bicycles for daily transport, recreation and sport coupled with increased general awareness of the environmental impact of some alternatives, has led to the renaissance of the bicycle. Cyclists often proceed by bicycle and then dismount to pursue various other activities. There continues to be a need for a way for bicyclists to readily swap between cycling and other means, such as walking or running while maintaining the greater effectiveness of riding which results from attaching the feet in some way to the pedals.
[0002] As a whole the bicycling community is supplied with a variety of bicycling footwear and associated bicycle pedal systems however all have practical limitations. Previously various segments of the bicycling community have been described as these groups tend to employ different types of bicycle pedals, fastenings and shoes.
[0003] The limitations of specialized clipless bicycle shoes is that they are designed for bicycling performance and not for any other daily activity. Proceeding on foot in specialized clipless bicycle shoes is uncomfortable dangerous and destructive to sensitive surfaces.
[0004] Bicycle pedals equipped with toe straps are an older generation of bicycle technology largely replaced by the superior technology of clipless bicycle pedals. Previous specialized bicycle shoes and pedals commonly equipped with toe straps required the user to actuate a fastening mechanism by hand.
[0005] A bicycle pedal and shoe-fastening device that requires actuation by hand is inherently dangerous. Bicycle pedals with toe straps are hazardous to actuate, unreliable and offer limited performance improvements. A bicyclist using bicycle pedals equipped with toe straps to fasten over standard shoes gains only marginal bicycling performance improvements as standard shoes do not have inflexible soles, a core feature of specialized bicycle shoes. Standard shoes fastened to a bicycle's pedals by toe straps readily detach, as only the tapering forefoot of the bicyclist's foot is fastened causing serious accidents. In order to actuate bicycle pedal toe straps to both attach and detach their shoes a bicyclist must perform a sequence of actions requiring skill and attention. To attach their shoes the bicyclists must, in turn for both sides of their bicycle, tilt their bicycle in order to lean down on either side of their bicycle so as to actuate the bicycle pedal's toe strap fasteners into a tight closed position around their shoes. While the bicyclist actuates the bicycle pedal toe straps they must also maintain balance, avoid getting clothing or body parts, particularly fingers, caught in the potentially moving parts of the bicycle, such as chain rings or rotating wheels and avoid other vehicles or objects in their path. In order to detach their shoes the bicyclist must actuate the bicycle pedal toe straps in a similar manner as to when attaching them, but actuate the straps into an open position.
[0006] In practice it is often impossible for a bicyclist to detach their shoes from their toe straps and pedals in an emergency situation. Bicyclists forcing their bicycle's pedals, whilst using toe straps, may suddenly detach from their toe straps and therefore their bicycles pedals thus leading to a risk of serious high speed accidents.
[0007] Bicycle pedals and toe straps do allow the user to wear standard shoes, and this can be attractive to users interested in either fashion or practical performance, however when employing bicycle toe straps to fasten standard shoes to a bicycle's pedals limited performance improvements are gained as standard shoes usually do not have inflexible soles, central to specialized bicycle shoes. Bicycle pedal toe straps are difficult to use. Bicycle pedal toe straps are hazardous to the user leaving a bicyclist exposed to a variety of physical risks, particularly fastening failure at speed or being struck by other vehicles whilst actuating bicycle pedal toe strap fastenings. Bicycle pedals and toe straps offer limited performance improvements.
[0008] Hybrid bicycle shoes have similar common traits with specialized clipless bicycle shoes. Hybrid bicycle shoes have cleats that are fastened onto their soles. Specialized bicycle shoes have inflexible soles, whilst hybrid bicycle shoes have similar, but semi-flexible soles intended to both facilitate improved cycling performance whilst flexing enough to allow reasonable performance whilst proceeding on foot.
[0009] Hybrid bicycle shoes have similar robust fasteners to those of specialized bicycle shoes, intended to firmly attach such shoes to the feet of the user so as to safely conduct and contain the forces involved whilst in use on a bicycle. Hybrid bicycle shoes are often well ventilated, similar to specialized bicycle shoes, designed to facilitate cooling of the users feet during robust activities.
[0010] As is common with compromise design solutions, hybrid bicycle shoes excel in neither of the functions which they are intended to perform. Hybrid bicycle shoes are inferior when compared to specialized bicycle shoes in terms of improving bicycling performance. By having semi-flexible soles hybrid bicycle shoes transfer less force less efficiently than specialized bicycle shoes. Hybrid bicycle shoes require greater skill to locate into clipless bicycle pedals, owing to their recessed cleats. When compared to standard shoes, hybrid bicycle shoes are problematic when performing tasks other than bicycling. Hybrid shoe's semi-flexible soles are uncomfortable when proceeding on foot for any distance. Hybrid bike shoes easily become wet as their ventilating materials offer little water resistance. Hybrid bicycle shoes still have cleat surfaces exposed which can easily damage floor surfaces as well as offering less grip than most standard shoes.
[0011] There are two common bicyclist's responses to the limitations of all current specialized bicycle pedal and shoe systems. The first is to carry two pairs of shoes, a pair of bicycle shoes and a pair of standard shoes. Cyclists who carry two pairs of shoes change between each pair of shoes where the respective merits of each pair of shoes best fit the user's activities, hence bicycle shoes for bicycling and standard shoes for other activities. Switching between pairs of shoes is inconvenient and cumbersome, requiring the bicyclist to secure and account for one pair of their shoes at all time, whilst the user is wearing their other pair of shoes.
[0012] The second common bicyclist's response to the limitations of all current specialized bicycle pedal and shoe systems is to simply avoid all current specialized bicycle pedal and shoe systems. Cyclists who make do with standard treadle bicycle pedals and standard shoes may well be interested in enhancing their bicycling performance. Cyclists who make do with standard treadle bicycle pedals and standard shoes may be most interested in practical performance yet find all specialized bicycle pedals and shoes unpractical, insecure, unsafe or unfashionable and so simply avoid using all bicycle shoes and specialized pedals.
[0013] Clipless bicycle pedals have been known in the art. Most of them however require the fastening system to be held in constant tension around the user's foot or footwear, thereby making such a device uncomfortable, inefficient and dangerous having substantial potential for the user's feet and footwear to disengage when not desired. For example, FR 2888205 discloses a clipless bicycle pedal comprising of a device with front and rear fasteners that are fastened to inflexible plates that can fasten bicycle clipless pedal cleats; such that the fastening system must be held in constant tension around the rear of the user's ankles. However, this allows the user's feet and footwear to dislocate approximately tangentially to the axis making such a device uncomfortable, inefficient and dangerous having substantial potential for the user's feet and footwear to disengage when not desired.
[0014] Another clipless bicycle pedal devise is described by patent NL10161151 comprising an inflexible sole plates that clipless pedal cleats can be fastened, with toe covers and backstops at right angles to the ankle areas of inflexible sole plates, with fasteners that are held in constant tension around the user's feet and footwear. Again, since this relies on the user's feet and footwear being held in constant tension along a single axis it is found that when force is applied approximately tangentially to the axis that the device is fastened that great potential exists for dislocation pinching and disengagement of the user's feet and footwear from the device.
[0015] U.S. Pat. No. 4,055,005 discloses a clipless bicycle pedal comprising of inflexible sole plates that bicycle pedal cleats can be attached with toe covers and backstops at right angles to the ankle areas of the described device's inflexible sole plates and fasteners that are held in constant tension around the user's feet and footwear. This is found to be uncomfortable and dangerous as the potential exists for accidental disengagement of the user's feet and footwear.
[0016] DE 4241270 discloses inflexible sole plates that are adjustable in length that fasten a fastening system consisting of toe fasteners and ankle fasteners and backstops at right angles to the ankle areas of inflexible sole plates, sole plates that can fasten clipless bicycle pedal cleats. The ankle fasteners are held in constant tension around the user's feet and footwear forcing the user's feet and footwear against backstops.
SUMMARY OF THE INVENTION
[0017] The invention relates to a cyclic pedal device comprising a sole portion, a first portion for reversible engagement with the foot of a cyclist and a second portion for reversible engagement with a pedal such that the device is substantially fastened around the user's feet and footwear by means of a trivalent ankle fastening system. The ankle fastening system in accordance with the present invention may comprise of a number of integrated aspects which in concert form the devices ankle fastening system.
[0018] In one embodiment of the invention, the ankle fastening system comprises of two sides positioned along two separate axis from two points that extend from either sides of the sole plates to the center of rotation of the users ankle.
[0019] The two sides of the ankle fastening system may be fastened to the sole plates at approximately right angles on each side of the sole plate.
[0020] In another embodiment of the present invention, the ankle fastening system comprises two portions that form arcs around the user's ankle such that, in an engaged position, one arc fastens the user's feet and footwear in the front of the user's ankle over the user's forefoot and the other aspect forms an arc that fastens the user's feet and footwear behind the users ankle.
[0021] Preferably, the sole plate is substantially inflexible
[0022] In another embodiment, the cyclic pedal device further comprising cutouts or holes in the sole plates.
[0023] The cyclic pedal devices in accordance with the invention may be used for any suitable type of cycle, but most preferably a bicycle.
