Abstract

An interlock lever for actuating a latch member of a machine is disclosed. The latch member is configured to lock a hood of the machine in a closed position thereof. The machine has an input member being movable in a first direction to move the hood towards an opened position and a second direction to move the hood towards the closed position. The interlock lever includes a body coupled to a frame of the machine and a slot defined in the body. The body is movable between a first position and a second position. In the second position of the body, the slot allows movement of the input member in the first direction and actuates the latch member to allow the hood to move from the closed position. In the first position of the body, the slot prevents movement of the input member in the first direction.

First claim

What is claimed is:

1. A latch system for a hood of a machine, the machine having an input member, the input member being movable in a first direction to cause the hood to move towards an opened position and a second direction to cause the hood to move towards a closed position, the latch system comprising:
a latch member moveable between a locked configuration and an unlocked configuration, wherein in the locked configuration the latch member retains the hood in the closed position thereof, and wherein in the unlocked configuration the latch member allows movement of the hood from the closed position thereof; and
an interlock lever including a body, the interlock lever movable between a first position and a second position, wherein in the first position the body blocks movement of the input member in the first direction, and wherein in the second position, the body of the interlock lever does not block movement of the input member in the first direction, and wherein movement of the interlock lever from the first position to the second position moves the latch member to the unblocked position.

2. The latch system of claim 1 , wherein in the first position of the interlock lever, the input member is configured to be moved in the second direction.

3. A latch system for a hood of a machine, the machine having an input member, the input member being moveable in a first direction to cause the hood to move towards an opened position and a second direction to cause the hood to move towards a closed position, the latch system comprising:
a latch member moveable between a locked configuration and an unlocked configuration, wherein in the locked configuration the latch member retains the hood in the closed position thereof, and wherein in the unlocked configuration the latch member allows movement of the hood from the closed position thereof; and
an interlock lever defining a slot therethrough and being moveable between a first position and a second position, wherein in the first position the slot of the interlock lever blocks movement of the input member in the first direction, and wherein in the second position the interlock lever causes the latch member to move to the unlocked configuration thereof and allows movement of the input member in the first direction.

4. The latch system of claim 3 , wherein in the first position of the interlock lever the slot allows movement of the input member in the second direction.

5. The latch system of claim 3 , wherein the interlock lever comprises a pivot member to pivotally couple the interlock lever to a frame of the machine, and wherein the interlock lever is movable between the first position and the second position about the pivot member.

6. The latch system of claim 3 , wherein the interlock lever further comprises a coupling portion defined between the pivot member and the slot.

7. The latch system of claim 6 , further comprising a cable member coupled to the coupling portion of the interlock lever and the latch member, wherein in the second position of the interlock lever, the cable member actuates the latch member to the unlocked configuration thereof.
