Abstract

A mast and integral display mount for a material handling vehicle are shown. The mast mounts a locating apparatus such that a locating axis of the locating apparatus is coaxial with a steering axis of the steerable drive wheel of the material handling vehicle. An integral display mount may include a display unit and display screen housed in a display housing that is integral with the steering handle of the vehicle. The integral nature of the display mount allows the display unit to move with the steering handle during steering of the vehicle.

First claim

The invention claimed is:

1. A mast for a material handling vehicle that includes a body, a battery compartment, a locating apparatus, a steering mechanism with a steering handle, and a steerable drive wheel coupled to the body and controlled by the steering mechanism, the steerable drive wheel including a steering axis, the mast comprising:
a first support member coupling to the body of the material handling vehicle and mounting the locating apparatus above the body of the material handling vehicle, the first support member including a portion of the first support member that projects at an angle towards a front of the material handling vehicle, the portion of the first support member that projects at an angle towards a front of the material handling vehicle configured such that a locating axis of the locating apparatus is coaxial with the steering axis and a mass of the locating apparatus is transferred to the material handling vehicle at a position behind the steering axis.

2. The mast of claim 1 , wherein the portion of the first support member that projects at an angle towards a front of the material handling vehicle provides clearance near the battery compartment of the material handling vehicle.

3. The mast of claim 1 , wherein the mast further includes a second support member, the second support member including a second angled portion that projects at an angle towards the front of the material handling vehicle.

4. The mast of claim 1 , wherein the locating apparatus provides sensing and navigation capabilities to automatically guide the material handling vehicle.

5. An automatic guided material handling vehicle comprising:
a body;
a fork carriage with load bearing forks;
a steering mechanism including a steering handle;
a steerable drive wheel coupled to the body and controlled by the steering mechanism, the steerable drive wheel including a steering axis;
a locating apparatus for providing sensing and navigation capabilities to automatically guide the automatic guided material handling vehicle, the locating apparatus including a locating axis; and
a mast for mounting the locating apparatus above the body, the mast including a support member coupled to the automatic guided material handling vehicle, the locating apparatus being mounted to the mast such that the locating axis is coaxial with the steering axis.

6. The automatic guided material handling vehicle of claim 5 , wherein at least a portion of the support member projects at an angle towards a front of the automatic guided material handling vehicle.

7. The automatic guided material handling vehicle of claim 6 , further including a battery compartment for housing a battery, wherein the portion of the support member projecting at an angle towards the front of the automatic guided material handling vehicle provides clearance near the battery compartment.

8. The automatic guided material handling vehicle of claim 6 , wherein the portion of the support member projecting at an angle towards the front of the automatic guided material handling vehicle provides clearance for manual operation of the steering handle.

9. The automatic guided material handling vehicle of claim 8 , the mast further including an additional support member and a cross support that engages the support member and the additional support member.

10. The automatic guided material handling vehicle of claim 9 , wherein the additional support member is a mirror image of the support member.

11. The automatic guided material handling vehicle of claim 9 , wherein the cross support is configured to engage the support member and the additional support member at a height of the automatic guided material handling vehicle below the steering handle.

12. The automatic guided material handling vehicle of claim 5 , wherein the locating apparatus includes at least one of a camera and a motion sensor.
