摘要： A steering mechanism includes a handle with a tiller arm coupled to the handle via a flexible joint allowing relative movement of the handle about the tiller arm. A handle centering mechanism forming part of the steering mechanism includes a first end fixedly secured to the handle and a second end extending into a channel of the tiller arm. The second end compresses bumpers disposed on opposing sides of the second end. The bumpers urge the handle toward a neutral position wherein when a force is applied to move the handle away from a home position relative to the tiller arm, one of the compressed bumpers of the pair of compressed bumpers is further compressed. When the force is removed, the handle is returned to the home position by action of the pair of compressed bumpers. Preferably, the steering mechanism includes a torque sensing arrangement having a sensor and a magnet. The sensor produces a signal based on movement of the handle relative to the tiller arm by sensing changes in the magnet field of the magnet proportional to the torque exerted on the handle regardless of the angle of the tiller arm.

摘要： A power steering assist system for a hand-steered pallet truck includes a joint assembly having a pivot joint, handle biasing mechanism, and a torque sensing arrangement. The pivot joint includes a pair of needle bearings and pivot pin disposed within a pivot block that provides a flexible connection between a handle and a tiller arm. The handle biasing mechanism includes a cantilevered beam spring and two cam rollers that resists an operator steering force applied to the handle and further, centers the handle with respect to the tiller arm after the force is released. The torque sensing arrangement includes a magnet and a non-contact magnetoresistive (MR) sensor that measures movement of the handle relative to the tiller arm which is used to determine operator steering intent, i.e., the amount of steering force applied to the handle. The MR sensor provides accurate torque measurements regardless of the angle of the tiller arm. The steering assist system further includes a driving unit with a steerable drive wheel, and a servomotor. The amount of steering assist provided by the servomotor to the drive wheel is at least partially determined based on the measured operator steering intent.

摘要： A selectively actuatable lighter device is disclosed which includes a body defining reservoir for containing a combustible gaseous medium such as butane, and having a valve arranged to be selectively actuated between a normally closed position and an open position which permits the exit of the gaseous medium. Such lighter can selectively produce sparks at a location proximate to the gaseous medium exit to ignite the gaseous medium. Such lighter device embodies a resiliently releasable latch which normally prevents actuation of a valve actuator to the open position thereby preventing actuation of the valve. The latch is selectively movable to a position out of interference with the valve actuator, so that the gaseous medium may be released and ignited by the sparks. The latch is resiliently structured and mounted such that once a flame is produced and the valve actuator is released, the latch returns to its closed or latched position to prevent actuation of the valve to the open position by prevention of the pivotal motion of the valve actuator. To "re-use" the lighter, the latch must again be moved to an unlatched position so that the valve actuator can be opened for subsequent ignition of the gaseous medium.

摘要： The lighter of the present invention provides a resiliently deformable guard that covers a portion of the striking wheel assembly. To operate the lighter, a user exerts sufficient pressure to depress the guard before rotating the striking wheel assembly. The present invention provides retention mechanisms to make removal of the guard more difficult. Further, the lighter of the present invention provides brake members to prevent the rotation of the striking wheel assembly when the user attempts to release fuel prior to rotating the striking wheel assembly.

Such lighter can selectively produce sparks at a location proximate to the gaseous medium exit to ignite the gaseous medium. Such lighter embodies a resiliently releasable latch means which normally prevents actuation of a valve actuator to the open position thereby preventing actuation of the valve. The latch means includes a latch which is selectively movable to a position out of interference with the valve actuator, so that the gaseous medium may be released and ignited by the sparks. The latch means is resiliently structured and mounted such that once the valve actuator is depressed and released, the latch returns to its closed or latched position to prevent actuation of the valve to the open position. The lighter according to the present invention also resists forcible disabling of the latch by providing an angled portion at one of the contact points of the latch with the housing (or of the latch with the valve actuator), so that the latch will displace to a secondary position. This displacement absorbs the excessive force applied without deformation or damage to the latching mechanism, allowing for the latch to return to the normal closed or latched position after release of the excessive force.

摘要： A child resistant lighter device is disclosed which includes a body defining reservoir for containing a combustible gaseous medium such as butane, and having a valve arranged to be selectively actuated between a normally closed position and an open position which permits the exit of the gaseous medium. Such child resistant lighter can selectively produce sparks at a location proximate to the gaseous medium exit to ignite the gaseous medium, and a safety mechanism prevents actuation of the valve to the open position when sparks are produced. Such child resistant lighter device embodies a resiliently releasable safety latch which prevents the actuation of the valve actuator to the open position. The safety latch is selectively movable to a position out of interference with the valve actuator, so that the gaseous medium may be released and ignited by the sparks. The safety latch is resiliently structured and mounted such that once a flame is produced and the valve actuator is released, the safety latch returns to its closed or locked position to prevent actuation of the valve actuator to the open position by prevention of the pivotal motion. To "re-use" the lighter, the safety-latch must again be moved to the open or unlocked position so that the valve actuator can be opened for subsequent ignition of the gaseous medium. Such mechanism is difficult for a young child to light, but is capable of actuation by adults.

摘要： A burner assembly for gas-fueled lighters includes a metallic burn chamber rigidly connected to a fuel metering valve. The burner and fuel valve are rigidly connected through an insulated coupling component. This provides a more reliable structure and reduces heat transfer from the burner to the fuel source, reducing vapor lock conditions.
