Abstract:
The clipless bicycle pedal system includes two cylinders (14, 10), one on the bicyclist's shoe, the other on the pedal, which closely interfit with one another, one member having laterally projecting pins (12), the other including circumferential slots (34) for receiving the laterally projecting pins (18), there being cam means (26, 36) to assist in interfitting the two members (14, 10) by pressing them together and to permit their separation by rotational movement of one member relative to the other.
Abstract:
A device and method for releasably attaching a shoe to a binding pedal. The shoe mates with a smoothly curved frame (10) attached by an adjustable and releasable strap (14). The frame (10) is adjustably attached to a platform (12) containing cleats (40, 44) which clip into the binding pedals.
Abstract:
An apparatus for changing the leverage of a bicycle pedal (5/41) by telescoping the pedal (5/41) on the pedal arm (13/51) during rotation of the pedal arm (13/51) and pedal guide (1/39) around the pedal axis; the apparatus comprising a pedal guide (1/39) which includes a lead bolt (7/45) and has the pedal (5/41) attached thereto, a pedal arm (13/51), a cam plate (31/33) a cam ring (32/34), a ring bearing (127/129), a pedal axle (19), a sprocket (97), and a spindle housing (12). The lead bolt (7/45) of the pedal guide (1/39) rotatably attaches to the cam ring (32/34) which peripherally encloses the ring bearing (127/129). The ring bearing (127/129) is peripherally located around the pedal arm (13/51) and pedal guide (1/39) rotate, the cam ring (32/34) and cam plate (31/33) control the telescoping motion of the pedal (5/41) and pedal guide (1/39) by controlling the movement of the lead bolt (7/45) of the pedal guide (1/39). The pedal guide (1/39) slides on the pedal arm (13/51). The sprocket (97) is fixedly connected to the pedal axle (19).
Abstract:
The invention relates to a single-pedal system for controlling the speed of the engine and the braking effect in a motor vehicle. A pedal holder (1) is mounted for movement from a resting position for effecting braking of the vehicle. A pedal (3) is movably supported on the pedal holder (1) for controlling the speed of the engine of the vehicle. A returning means is arranged to return the pedal holder (1) to the resting position. A locking means (10) is arranged to hold, in a non-braking state of function of the system, the pedal holder (1) in its resting position and, when passing to a braking state of function of the system, to release the pedal holder (1) from the resting position if a compressive force exceeding a predetermined value is applied to the latter.
Abstract:
A pedal operating mechanism (10) particularly for the operation of vehicle brake or clutch master cylinders (14, 15) having a mounting bracket (11), a pedal (12) pivotally mounted on the bracket via a pivot pin (13) and an actuation linkage (16) for operatively connecting the pedal to the master cylinder(s). The pivot (13) is adjustably mounted (31, 32) on the bracket (11) so that the operating ratio of the pedal is adjustable. This adjustement may be made by operation of an adjustment means sited remote from the pedal.
Abstract:
An adjustment device for an automobile control pedal (10) which is capable of pivotably adjusting the control pedal (10) relative to a datum point, such as the eyelet (36) of a cylinder pushrod (34). The adjustment device allows the control pedal (10) to be optimally positioned to suit the needs of a particular driver. The control pedal (10) can be pivotally attached to a frame (14) in any conventional manner, such as with a pivot pin (24). The adjustment device is mounted alongside the control pedal (10) and to the pushrod eyelet (36) without the need of additional support hardware other than a means for maintaining a predetermined distance between the pushrod eyelet (36) and the pivot pin (24) of the control pedal (10). Consequently, the adjustment device can be readily adapted to fit conventional control pedal assemblies without significant modification. The adjustment device includes a camming device (28) which slidably abuts the pedal arm (20) such that rotation of the camming device (28) causes pivotable movement of the pedal arm (20) relative to the datum point. The camming device (28) preferably has its axis of rotation coincident with the datum point and is maintained a predetermined distance from the pivot of the control pedal arm (20) by a spacing device, such as a link (40). The adjustment device also includes a cam driving device (44) for rotating the camming device (28) about its axis of rotation to produce a corresponding displacement of the control pedal arm (20).
Abstract:
A bicycle pedal attachment having an elongated strap (20) that is diagonally arched and attached to a bicycle pedal (20) such that the front end (21) of the strap (20) is secured adjacent the front inside edge of the pedal (30) and the rear end (22) of the strap (20) is secured to the bicycle pedal (30) adjacent its rear outside edge. The structure allows the bicyclist to insert his foot into the pedal attachment toe first and at a diagonal angle through the arched loop formed by the strap (20) and then by pivoting his heel inwardly the foot of the bicyclist will be captured with tension applied to the front outside of the foot across the top of the foot and also to the inside of the foot.
Abstract:
Apparatus is provided for enhancing the ability of a rider to propel a bicycle, making it possible to provide a significant increase in the amount of useful work that may impart. Included is a crank (53) and a sprocket (73) which can rotate relative to one another. A guide (91) is fixedly attached to the sprocket (73), and a sliding member is configured to engage the guide such that rotation of the crank will urge the sliding member (99) along the guide (91). A spring (141) is included which is deformed as the sliding member (99) is urged along the guide. Hence, during a power stroke, an applied force on the pedal (79, 81) causes the arm portion (65) to advance rotationally ahead of the sprocket position during the first half of the stroke, urging the sliding member (99) along the guide (91), and deforming the spring (141). The spring (141) thus stores the work performed on it as potential energy. During the second half of the stroke the spring (141) releases the stored potential energy to the sprocket (73).
Abstract:
The assembly for a motor vehicle includes an upper carrier structure (29) and a pedal arm (28a) extending downwardly therefrom. The carrier structure (29) is slidably mounted on a hollow guide rod (16b) extending rearwardly from a transmission housing (16a). A nut (32) is positioned slidably within the guide rod (16b) and a screw shaft (48c) extends rearwardly from the transmission housing (16a) for threaded engagement with the nut (32). The nut (32) is drivingly connected to the carrier structure (29) so that linear movement of the nut (32) within the guide rod (16b) upon rotation of the screw shaft (48c) produces movement of the pedal assembly along the guide rod (16b). In a first embodiment, the transmission housing (16a) is mounted on an arm (14) which is pivotally mounted on the vehicle firewall (22). In a second embodiment, the transmission housing (112a) is fixedly mounted on the vehicle firewall (122) and the pedal arm (146) is pivotally mounted on the carrier structure (113) and controls a potentiometer (160) carried by the carrier structure (113).
Abstract:
A dual control device for actuating the pedals (16, 17, 18) of a vehicle (6). The device comprises three mechanical sensors (2, 3, 4) generating signals representing the actions of a user's feet, an electrical control circuit (37) receiving said signals and using them to control the rotation of three winch drives (22, 23, 24) connected to the respective mechanical pull wires of the pedals (16, 17, 18) so that they can selectively draw said pedals closer to the floor (19) of the vehicle. Each drive is preferably combined with a position sensor (34, 35, 36) having a variable electrical response depending on the position of said drives. Furthermore, the electrical circuit (37) is connected to said position sensors to provide automatic control of the position of the mechanical pull wires (101, 111, 121) slidably mounted in sleeves and connected to the pedals (16, 17, 18), depending on the electrical responses of the position sensors.
