Abstract

A shock pallet assembly allows transport or movement of tall rack-mounted information handling systems (IHSes) without tipping. The shock pallet assembly can resiliently, manually or automatically retract for placement near a wall of a transport conveyance to achieve a greater shipping density of IHSes. The shock pallet assembly can include a bottom structure having a pair of parallel apertures to receive tines of a forklift. Resilient padding is positioned on a top surface of the bottom structure to provide shock dampening. A top deck is attached on top of the resilient padding and bottom structure to form a shock pallet that receives a racked-mounted IHS for transport and movement. An anti-tip mechanism is attached to a lateral side of the shock pallet to prevent tipping of the rack-mounted IHS.

Claims

1. A pallet assembly for rack-mounted information handling systems (IHSes), the pallet assembly comprising:

a bottom structure having a pair of parallel apertures to receive tines of a forklift;

resilient padding that is positioned on a top surface of the bottom structure to provide shock dampening;

a top deck attached on top of the resilient padding and bottom structure forming a shock pallet to receive a racked-mounted IHS during transporting or moving of the IHS; and

an anti-tip mechanism comprising;

a base extender that is attachable at a first end to the shock pallet and that has a second end that is positionable between a retracted position proximate to a lateral side of the shock pallet and an extended position to rigidly contact a spaced-apart portion of an underlying surface that also supports the bottom structure; and

a positioning member attached to the base extender to selectably extend the base extender between the retracted position and the extended position to prevent tipping of the rack-mounted IHS.

2. The pallet assembly of claim 1, wherein the positioning member comprises a passively resilient component that has a relaxed state in the extended position of the base extender and that has a constrained state in the retracted position of the base extender.

3. The pallet assembly of claim 2, wherein:

the base extender comprises a vertical spindle that is attachable to the pallet assembly and comprises a pallet safety arm having the first end received by the vertical spindle for horizontal rotation and having the second end to rigidly contact the underlying surface; and

the resilient component of the positioning member comprises a torsion spring received around the vertical spindle and having a moving end attached to the pallet safety arm and having a fixed end coupled to the shock pallet.

4. The pallet assembly of claim 2, wherein:

the base extender comprises a pallet safety arm slideably attached to the shock pallet for horizontal translation; and

the resilient component of the positioning member comprises a compression spring having a moving end attached to the pallet safety arm and having a fixed end attached to the shock pallet.

5. The pallet assembly of claim 2, wherein:

the base extender comprises a piston slideably received for horizontal translation within a bore that is attached to the shock pallet;

the resilient component comprises compressed gas; and

the positioning member comprises a pneumatic pressure system to receive and to contain the compressed gas between the bore and the piston.

6. The pallet assembly of claim 2, wherein:

the base extender comprises a bladder;

the resilient component comprises compressed gas or fluid; and

the positioning member comprises an inflation system to receive the compressed gas or fluid into the bladder to extend and make rigid the bladder.

7. The pallet assembly of claim 1, wherein the positioning member comprises a manually actuated mechanism.

8. The pallet assembly of claim 7, wherein:

the base extender comprises a scissoring extension bracket; and

the manually actuated mechanism of the positioning member comprises a jack screw mechanism.

9. The pallet assembly of claim 7, wherein:

the base extender comprises a pilot safety arm; and

the manually actuated mechanism of the positioning member comprises fasteners to attach the first end of the pilot safety arm to the shock pallet, wherein the retracted position of the base extender comprises a stowed state.

10. The pallet assembly of claim 1, wherein the positioning member comprises an electrically-powered actuator.

11. The pallet assembly of claim 10, further comprising:

a proximity sensor to detect a surface within an extension area that is proximate to the lateral side of the shock pallet;

wherein the positioning member comprises an electrically-powered actuator; and

a processor in communication with the proximity sensor and the electrically-powered actuator to respond to the proximity sensor not detecting the surface within the extension area by controlling the electrically-powered actuator to extend the base extender.

12. A method of constructing a pallet assembly for rack-mounted information handling systems (IHSes), the method comprising:

forming a pair of parallel apertures to receive tines of a forklift in a bottom structure;

positioning resilient padding on a top surface of the bottom structure to provide shock dampening;

attaching a top deck on top of the resilient padding to the bottom structure to form a shock pallet to receive a racked-mounted IHS for transport and movement; and

attaching anti-tipping mechanism to the pallet assembly to prevent tipping during transport or movement of the rack-mounted IHS that is attached to the top deck, wherein attaching the anti-tipping mechanism includes;

attaching a first end of a base extender to the shock pallet, wherein the base extender has a second end that is positionable between a retracted position proximate to a lateral side of the pallet assembly and an extended position to rigidly contact a spaced-apart portion of an underlying surface that also supports the bottom structure; and

attaching a positioning member to the base extender to selectably extend the base extender between the retracted position and the extended position to prevent tipping of the rack-mounted IHS.

13. The method of claim 12, wherein the positioning member comprises a passively resilient component that has a relaxed state in the extended position of the base extender and that has a constrained state in the retracted position of the base extender.

14. The method of claim 12, wherein the positioning member comprises a manually actuated mechanism.

15. The method of claim 12, wherein the positioning member comprises an electrically-powered actuator.

16. The method of claim 15, wherein:

the positioning member comprises an electrically-powered actuator; and

attaching the position system comprises;

providing a proximity sensor to detect a surface within an extension area that is proximate to the lateral side of the pallet assembly; and

providing a processor in communication with the proximity sensor and the electrically-powered actuator to respond to the proximity sensor not detecting the surface within the extension area by controlling the electrically-powered actuator to extend the base extender.
