초록 ▼

Disclosed herein is a work vehicle, such as a tractor, having a frame, a compartment, a hood coupled to the frame and configured to at least partially cover the compartment when disposed in a closed position; and a mechanism coupling the hood to the frame, the mechanism configured to move the hood between the closed position and at least one at least partially opened position, the mechanism including at least one four-bar linkage, a first bar of the linkage including a portion of the frame and a second bar of the linkage including a portion of the hood, the vehicle further having a support member configured to engage the at least one linkage at predetermined positions and thereby immobilize the hood against further changes in position. The support member has a first portion movably secured to the vehicle, a second portion configured as a handle, and an intermediate portion disposed between the first and second portions and including at least one catch member disposed to engage an engaging member of the at least one linkage. The vehicle includes a primary latch for securing the hood to the frame in the closed position, and a secondary latch for backing up the primary latch in the closed position by engaging a support member catch with an engaging member of the at least one linkage. The vehicle further comprises a coupler coupling the support member to the primary latch whereby the support member functions as a single lever actuating device of both the primary and secondary latches. The vehicle further comprises at least one biasing device selectable in spring constant and preload and configurable in locating of mounting whereby a particular biasing device may be used to balance a hood of particular weight and weight distribution in the open, closed, and intermediate positions.

[ What is claimed is:] [1.]1. A work vehicle comprising:a frame;a compartment;a hood coupled to the frame, and configured to at least partially cover the compartment when disposed in a first position wherein the hood is closed; anda mechanism coupling to the hood to the frame, the mechanism configured to move the hood between the first position and at least a second position, wherein the hood is at least partially opened when in a position other than the first position;the mechanism including at least one four-bar linkage configured to pivot and translate the hood, a first bar of the linkage including a portion of the frame, a second bar of the linkage including a portion of the hood, a third bar of the linkage pivotably coupled to each of the first bar and the second bar, and a fourth bar of the linkage pivotably coupled to each of the first bar and the second bar, the vehicle further having a support member configured to engage the at least one linkage at predetermined positions corresponding to the first and at least second positions of the hood and thereby immobilize the at least one linkage, and thereby the hood, against a further change in position in at least one direction, wherein the support member has a first portion movably secured to the vehicle, a second portion configured as a handle, and an intermediate portion disposed between the first and second portions and including at least one catch member disposed to engage an engaging member of at the at least one linkage and thereby immobilize the at least one linkage when the hood is in a predetermined position, the at least one catch member engageable and disengageable by movement of the support member with respect to the vehicle.
