  • Patent number: 6622806
    Abstract: An all terrain vehicle has a frame assembly. A pair of front wheels and a pair of rear wheels support the frame assembly. A front fender assembly extends over at least a portion of the front wheels. An engine is disposed between the front wheels and the rear wheels. The engine is water-cooled using a radiator and fan combination that is positioned forward of the engine. A belt drive forms a portion of a transmission that transfers power from the engine to at least the rear wheels. The belt drive is air cooled with air that is pulled into the belt drive by fans positioned within a belt case. The air is drawn from an air chamber formed within the front fender assembly. The chamber is positioned vertically higher than the radiator and fan combination and rearward thereof. The air passes between the chamber and the belt case through a duct. The duct extends downward and incorporates a central trap portion.

  • Patent number: 6581716
    Abstract: An all terrain vehicle includes a frame assembly and a rear arm that is pivotally attached to the frame assembly. A rear arm bracket is secured to the frame assembly. A pivot axis is defined through a portion of the rear arm bracket. The pivot axis is disposed rearward of the portion of the frame assembly to which the rear arm bracket is attached. The rear arm is connected to the rear arm bracket such that the width of the rear arm at its connection to the frame assembly is at least as large as the width of the frame assembly at that location.

  • Patent number: 6478103
    Abstract: An all terrain vehicle comprises a compact layout for a brake system. The all terrain vehicle includes a front fender assembly, which is positioned above at least one front wheel, and a rear fender assembly, which is positioned above at least one rear wheel. An engine is supported by a frame assembly and is positioned between the front wheel and the rear wheel. A longitudinal plane extends along an outer lateral surface of the engine and a transverse plane extends along either a rearmost portion of the front fender assembly, a forwardmost portion of a foot step or an intersection between the front fender assembly and the foot step. A master cylinder of the braking system is disposed forward of the transverse plane and inward of the longitudinal plane. The master cylinder is independently operated by a hand actuator and a foot actuator. Movement of either of the actuators does not move the other of the actuators.

  • Patent number: 6454039
    Abstract: A gear shift arrangement for an all terrain vehicle is provided. The all terrain vehicle comprises a frame defining an engine compartment. The frame is supported by two or more front wheels and two or more rear wheels. An engine is mounted in the engine compartment and is drivingly coupled to one or more of the wheels through a suitable drive train. A fender assembly is disposed above the front wheels and has a recess formed therein. A gear shift actuator is at least partially disposed in the recess. The recess can be disposed inboard of an inner surface of the front wheels and rearward of the rearmost surface of the front wheels. The actuator is sized and positioned to lie generally below an upper plane defined through either a front fender assembly, a carrying rack mounted to the front assembly, or both.

  • Patent number: 6164673
    Abstract: An all terrain vehicle has an adjustable suspension system. The adjustable suspension system features a first spring and a second spring. An intermediate member is positioned between the two springs and may travel in an axial direction along with at least a portion of one of the springs. A travel limiting member, movable by a cam and follower system, is positioned relative to the intermediate member such that the travel limiting surface may stop the movement of the intermediate member thereby disabling at least one of the first and second springs. The cam and follower mechanism is operated via a shifting lever positioned within a recess proximate a seat of the all terrain vehicle and in a location protected from the undercarriage of the all terrain vehicle.

  • Patent number: 6009308
    Abstract: A selective calling receiver detects a message and information identifying the sender, from the radio signal when the judgement circuit judges the received selective calling number is the same as the receiver's own selective calling number. After detecting, a display indicates the detected message and sender's information, and a call notification circuit notifies a user of calling. The receiver may indicate the name assigned to the received sender's telephone number as the sender's information. The receiver may perform emergency call notification when the received message is an emergency message indicated by an emergency code number. Further, the receiver may be modified such that the notification circuit performs different types of call notification indicated by the notification indicator assigned to the sender's telephone number.

  • Patent number: 5959544
    Abstract: A radio selection call receiver with message display includes a control circuit 40 for controlling the display of messages and a secret mode. The receiver determines whether or not secret setting information is included in a received message and whether or not a user has input or transmitted secret cancellation information. The receiver detects all or part of predetermined first information from received messages, and displays at least one second information set beforehand by a user corresponding to the first information. Display is thereby limited to the second information, which a third person cannot identify. This allows the authorized user to identify callers without inputting or transmitting a secret cancellation code.

  • Patent number: 5955962
    Abstract: In a radio selective calling receiver, a controller automatically writes time information and message information included in a received paging signal in a storage thereof if a particular code is included in the paging signal. If the particular code is absent from the paging signal, the controller urges the user of the receiver to decide whether or not the time information and message information should be written to the storage and should be reported on the date and hour designated by the time information.

  • Patent number: 5921339
    Abstract: A generally open, welded-up type of motorcycle frame wherein the pivot axis for the rear wheel suspension system is disposed forwardly of the rear end of the frame so as to provide a large degree of suspension travel with small angular movements and without necessitating a large wheel base. The construction also minimizes torsional bending and sheering forces on the frame members that support the rear wheel.
