A brake assembly for a manually-operated, height-adjustable wheeled vehicle according to a first aspect includes a brake cable assembly. The brake assembly includes a brake cable housing shaped to enclose an excess portion of the brake cable assembly. The brake assembly includes a cable adjuster coupled to the brake cable assembly. The cable adjuster is enclosed by the brake cable housing. There is additionally provided a wheel fork assembly for a manually-operated, height-adjustable wheeled vehicle according to a first aspect. The vehicle includes a frame member. The wheel fork assembly includes a mount shaped to couple with a lower end of the frame member of the vehicle. The mount has a longitudinal axis. The wheel fork assembly includes a wheel fork having a longitudinal axis offset from the longitudinal axis of the mount. The wheel fork is integrally coupled to and formed with the mount.

A handbrake structure includes a fixing base, a linking member and a brake handle. The fixing base is located on a handle of a moving apparatus. The linking member is located on the fixing base, wherein a first portion of the linking member is connected to a first brake wire, and a second portion of the linking member has a first limit part. The brake handle is located on the linking member, wherein a first portion of the brake handle is connected to a second brake wire. When the brake handle is rotated in a first direction, the brake handle pushes the first limit part to rotate the linking member, and the linking member pulls the first brake wire. When the brake handle is rotated in a second direction different from the first direction, the brake handle pulls the second brake wire.

A riding lawn mower includes a chassis having longitudinal support beam, a drive wheel, an electric motor coupled to the drive wheel, a suspended subframe having a longitudinal subframe beam pivotally coupled to the longitudinal support beam about a pivot axis, and a suspension device coupled between the longitudinal subframe beam and the longitudinal support beam. The longitudinal subframe beam at least partially supports the electric motor. The drive wheel and the electric motor are configured to translate relative to the chassis via the pivotal coupling between the longitudinal support beam and the longitudinal subframe beam.

A cable guide for a bicycle including a frame that has a bottom bracket. The cable guide includes a first guide that is attachable to the frame adjacent the bottom bracket and that supports a first cable, and a second guide that is attachable to the frame adjacent the bottom bracket and that supports a second cable. The first guide includes a first cable conduit that extends into the frame at a first angle, and the second guide includes a second cable conduit that extends into the frame at a second angle different from the first angle.

A child transport carrier includes a handle bar and a rotatable brake actuator disposed along a lengthwise axis of the handle bar. A first cable having a first end and a second end is coupled to the rotatable brake actuator. A first wheel brake of a first wheel is coupled to the first end of the first cable. Rotating the rotatable brake actuator around the lengthwise axis of the handle bar activates the first wheel brake.

A bicycle control cable is provided with a central wire, an outer case and a radial protrusion. The central wire includes at least one metallic strand defining a radially outermost surface of the central wire. The outer case surrounds at least a portion of an axial length of the central wire. The outer case has a radially innermost surface. The radial protrusion spirally extends along one of either the radially outermost surface of the central wire or the radially innermost surface of the outer case in a direction intersecting with a center longitudinal axis of the bicycle control cable. The radial protrusion reduces a sliding resistance of the central wire relative to the outer case. The central wire is configured and arranged to slidably move in an axial direction with respect to the center longitudinal axis of the bicycle control cable within the outer case to operate a bicycle component.

A park brake system for adjusting a tension in a brake cable that is coupled to a park brake. The park brake system can include a driver that is communicatively coupled to a microcontroller, and an actuator that is rotatably displaceable by operation of the driver. An equalizer assembly can be linearly displaced along the rotating actuator to adjust a tension in the brake cable. The microcontroller can monitor a current being drawn by the driver as the driver is operated, and generate instructions to cease operation of the driver upon the current reaching a predetermined current threshold that corresponds a maximum force that is to be applied by the park brake. The microcontroller can also, when the park brake is being released from a set position, count pulses outputted by an encoder in connection with determining whether the park brake has reached a running clearance position.

A riding lawn care vehicle (10) includes first and second drive wheels (32), a steering lever (34), a brake assembly (110), and a mechanical brake linkage assembly (120) including a cable tensioner (250). The brake assembly (110) may be operably coupled to at least one of the first and second drive wheels (32) to enable brakes to be selectively applied to the first and second drive wheels (32) based on a position of the steering lever (34). The cable tensioner (250) may be configured to activate the brake assembly (110) relative to the at least one of the first and second drive wheels (32) in response to the steering lever (34) being moved outwardly to an outboard position. The mechanical linkage assembly (120) may be configured to provide a greater amount of rotation of the cable tensioner (250) than a magnitude of rotation of the steering lever (34) when the steering lever (34) is moved from the inboard position to the outboard position.

An emergency controller includes an emergency stop switch to be activated upon detection of an emergency, a control section to be enabled upon activation of the emergency stop switch, and an emergency stop mechanism configured to execute and release braking by a brake mechanism under control of the control section. The control section is configured to perform execution control for causing the emergency stop mechanism to execute braking by the brake mechanism and for stopping operation of the engine upon the condition that the emergency stop switch is activated while the engine is in operation. The control section is configured to perform restoration control for causing the emergency stop mechanism to release the braking by the brake mechanism upon the condition that the emergency stop switch is deactivated and the engine is started.
