Abstract
A remote operating lever unit (20) for operating a brake unit (10) mounted to an wheeled vehicle is provided a lever (22) for operation by a user, a main body (24) holding the lever (22) in a displaceable manner and including a control unit for transmitting a signal to the brake unit (10) based on a displacement amount of the lever (22) from a neutral position thereof, a holder (26) holding the main body (26), and a connecting portion (245, 265) detachably engaging the main body (24) and the holder (26) at an arbitrary angle around an axis (X) perpendicular to a plane in which the lever (22) displaces.
Claims19
A remote operating lever unit for operating a brake unit mounted to a wheeled vehicle, comprising:
- a lever for operation by a user;
- a main body holding the lever in a displaceable manner and including a control unit for transmitting a signal to the brake unit based on a displacement amount of the lever from a neutral position thereof;
- a holder holding the main body;
- and
- a connecting portion detachably engaging the main body and the holder at an arbitrary angle around an axis (X) perpendicular to a plane in which the lever displaces;
- wherein the lever comprises the neutral position, a brake operation position where the lever is displaced in a first direction from the neutral position by a user, and a park brake position where the lever is displaced in a second direction opposite to the first direction, and the control unit of the remote operating lever unit transmits a signal for turning on a parking brake to the brake unit when the lever is set to the park brake position.
A remote operating lever unit for operating a brake unit mounted to a wheeled vehicle, comprising:
- a lever for operation by a user;
- a main body holding the lever in a displaceable manner and including a control unit for transmitting a signal to the brake unit based on a displacement amount of the lever from a neutral position thereof;
- a holder holding the main body;
- a connecting portion detachably engaging the main body and the holder at an arbitrary angle around an axis (X) perpendicular to a plane in which the lever displaces;
- and
- a calibration means for calibrating the signal to be generated based on the displacement amount of the lever from the neutral position, taking a change in a movable range of the lever from the neutral position to a full brake position as a result of adjustment of the neutral position of the lever with respect to and via the connecting portion, into account.
A remote operating lever unit for operating a brake unit mounted to a wheeled vehicle, comprising:
- a lever for operation by a user;
- a main body holding the lever in a displaceable manner and including a control unit for transmitting a signal to the brake unit based on a displacement amount of the lever from a neutral position thereof;
- a holder holding the main body;
- a connecting portion detachably engaging the main body and the holder at an arbitrary angle around an axis (X) perpendicular to a plane in which the lever displaces;
- and
- wherein the control unit of the remote operating unit comprises an accelerometer, and the control unit is configured to transmit a signal for turning on a parking brake or parking brake functionality to the brake unit when an output signal from the accelerometer does not change, or does not exceed a predetermined threshold, over a predetermined amount of time.
