Abstract

Protective assemblies for enclosures are described. An example apparatus includes a chassis configured to hold one or more electronic systems, a first frame configured to engage a first side of the chassis, a second frame configured to engage a second side of the chassis opposite the first side, and members attached between the first frame and the second frame using fasteners, the members extending between the first frame and the second frame to rigidly secure the first frame and the second frame against the chassis to create an enclosure comprising the first frame, the second frame, and the chassis, the members being exterior to the chassis.

First claim

What is claimed is:

1. An apparatus, comprising:
a chassis configured to hold one or more electronic systems;
a first frame configured to engage a first side of the chassis;
a second frame configured to engage a second side of the chassis opposite the first side; and
members attached between the first frame and the second frame using fasteners, the members extending between the first frame and the second frame to rigidly secure the first frame and the second frame against the chassis to create an enclosure comprising the first frame, the second frame, and the chassis, the members being exterior to the chassis, wherein the first frame comprises a shoulder to hold a first panel and a groove to mate with the chassis.

2. The apparatus as defined in claim 1 , wherein the first frame comprises first member extensions projecting outward from the chassis, the second frame comprises second member extensions projecting outward from the chassis opposite the first member extensions, and the members are detachably attached between the first member extensions and the second member extensions.

3. The apparatus as defined in claim 2 , further comprising:
first member caps configured to fit within openings of the first member extensions; and
second member caps configured to fit within openings of the second member extensions, the members configured to be attached between the first member caps and the second member caps.

4. The apparatus as defined in claim 3 , wherein the first member caps and the second member caps comprise metal and are configured to limit stress on the first member extensions and the second member extensions from attaching the members.

5. The apparatus as defined in claim 3 , wherein the first frame, the second frame, the first member caps, and the second member caps are configured to, when the apparatus is resting on a surface, provide spacing between the first frame and the surface and between the second frame and the surface regardless of an orientation of the apparatus with respect to the surface.

6. The apparatus as defined in claim 2 , wherein the first member extensions and the second member extensions are configured to project from the first frame and the second frame such that only the first member extensions, only the second member extensions, or ones of the first member extensions and the second member extensions contact a surface on which the apparatus is resting.

7. The apparatus as defined in claim 1 , wherein the first frame is configured to, when engaged against the chassis, hold the first panel against the first side of the chassis and provide a seal between the chassis and the first panel.

8. The apparatus as defined in claim 1 , further comprising:
a first gasket in the shoulder of the first frame between the first panel and the first frame, the first gasket to provide a first seal between the first panel and the first frame when the members are tightened between the first frame and the second frame.

9. The apparatus as defined in claim 8 , further comprising a second gasket in the groove to provide a seal between the first frame and the chassis when the members are tightened between the first frame and the second frame, the first gasket and the second gasket to cooperate to seal the chassis when the members are tightened between the first frame and the second frame.

10. The apparatus as defined in claim 1 , wherein the first frame and the second frame comprise metal or plastic.

11. The apparatus as defined in claim 1 , wherein the first frame comprises screw bosses to enable attachment of an accessory to the first frame.

12. The apparatus as defined in claim 1 , wherein the first frame and the second frame are only engaged to the chassis via attachment of the members between the first frame and the second frame.

13. The apparatus as defined in claim 12 , wherein the first frame and the second frame are engaged to the chassis by tightening the first frame and the second frame to the members with at least a threshold torque.

14. The apparatus as defined in claim 1 , wherein the chassis comprises at least one of a welding-type power supply, a wire feeder, an inductive heating power supply, a plasma cutter, a space heater, or a work radio.

15. The apparatus as defined in claim 1 , wherein the first frame and the second frame are to seal an interior chamber of the chassis from an exterior environment.

16. The apparatus as defined in claim 1 , wherein the members have an asymmetric cross-section to prevent rotation of the members when attached between the first frame and the second frame.

17. The apparatus as defined in claim 1 , wherein the second frame is a solid panel configured to cover a side of the chassis when the first frame is secured against the chassis.

18. An apparatus, comprising:
a chassis configured to hold one or more electronic systems;
a first frame configured to engage a first side of the chassis and to hold a first panel against the first side of the chassis;
a second frame configured to engage a second side of the chassis opposite the first side;
members attached between the first frame and the second frame using fasteners, the members extending between the first frame and the second frame to rigidly secure the first frame and the second frame against the chassis to create an enclosure comprising the first frame, the second frame, and the chassis, the members being exterior to the chassis, wherein at least one of the members comprises an axle; and
a wheel mounted to the axle.
