Abstract

A container includes an outer case with an interior volume sized to receive an equipment rack assembly, which in turn includes an inner (i.e., movable or slidable) platform assembly slidably coupled to an outer (i.e., non-movable or fixed) isolation assembly fixed to the case. In one example, the inner platform assembly slidably engages the outer isolation assembly using a joint, such as a dove-tail style joint. In addition, the outer isolation assembly may be supported by one or more shock absorbent devices positioned between the outer isolation assembly and the case. The shock absorbent devices may be positioned, oriented and tuned to achieve a desired amount of shock attenuation and damping.

Claims

1. A container for receiving equipment, the container comprising:

an outer case;

an isolation panel fixed to the outer case, the isolation panel having truss-shaped portions contiguously arranged between first and second end portions, wherein the individual truss-shaped portions have an apex and a base, and wherein a distance between the apex and the base, as measured in a direction generally perpendicular to the isolation panel, defines a thickness of the isolation panel, the isolation panel further having a slide engagement member adjacent to at least one truss-shaped portion, wherein the slide engagement member is positioned at least partially between the apex and the base of the truss-shaped portions;

a shock absorbent device located between the outer case and the isolation panel, the shock absorbent device having a primary load axis arranged at a desired angle relative to a horizontal reference plane; and

an inner member having an elongated guide member configured with a channel to slidably engage the slide engagement member of the isolation panel, the inner member sized to be received in the outer case.

2. The container of claim 1, wherein the slide engagement member and the elongated guide member cooperate together as a dovetail-style joint.

3. The container of claim 1, wherein the shock absorbent device includes a solid body made from an elastomeric material having a selected durometer.

4. The container of claim 1, wherein the desired angle of the primary load axis of the shock absorbent device is in a range of about 0 to about 90 degrees relative to the horizontal reference plane.

5. The container of claim 4, wherein the desired angle of the primary load axis of the shock absorbent device is about 45 degrees relative to the horizontal reference plane.

6. The container of claim 4, wherein the desired angle of the primary load axis of the shock absorbent device is about 30 degrees relative to the horizontal reference plane.

7. The container of claim 1, wherein the desired angle of the at least one truss-shaped portion is an obtuse angle.

8. The container of claim 1, the panel includes at least one planar portion proximate at least one truss-shaped portion.

9. An assembly receivable into an outer case of an equipment container, the assembly comprising:

an isolation plate fixed to an inner surface of the outer case, the isolation plate configured with ridges contiguously arranged between first and second end portions, the plate having at least one planar portion located adjacent one of the ridges, the plate further having a slide member coupled to the planar portion and extending generally parallel with the ridges, wherein the slide member extends from the planar portion a first distance in a direction generally perpendicular to the isolation plate, and wherein the ridges extend from the isolation plate a second distance in the direction generally perpendicular to the isolation plate, and further wherein the second distance is greater than the first distance; and

a shock absorbent device positionable between the outer case and the isolation member, the shock absorbent device having a primary load axis arranged at an angle that is substantially perpendicular to a surface of one of the ridges.

10. The assembly of claim 9, further comprising an inner member having an engagement portion configured to slidably engage with the slide member of the isolation plate, the inner member configured to receive the equipment.

11. The assembly of claim 10, wherein the slide member and the engagement portion are configured as a dovetail-style joint.

12. The assembly of claim 9, wherein the shock absorbent device includes a solid body made from an elastomeric material having a selected durometer.

13. The assembly of claim 9, wherein the desired angle of the primary load axis of the shock absorbent device is in a range of about 0 to about 90 degrees relative to a horizontal reference plane.

14. The assembly of claim 13, wherein the desired angle of the primary load axis of the shock absorbent device is about 45 degrees relative to the horizontal reference plane.

15. The assembly of claim 13, wherein the desired angle of the primary load axis of the shock absorbent device is about 30 degrees relative to the horizontal reference plane.

16. The assembly of claim 9, wherein adjacent ridge surfaces form an apex intersection with an obtuse angle.

17. The assembly of claim 9, wherein the shock absorbent device includes a variable spring rate.
