Abstract

A jack pad holding devices for supporting a jack pad to an aircraft, and a method for jacking an aircraft are provided. In one non-limiting example, the jack pad holding device includes a coupler housing configured for holding the jack pad. Coupling elements are coupled to the coupler housing and are configured to couple to the aircraft.

First claim

What is claimed is:

1. A jack pad holding device for supporting a jack pad to an aircraft, the jack pad holding device comprising:
a coupler housing configured for holding the jack pad, wherein the coupler housing includes a jack pad holder portion having a pocket formed therein for holding the jack pad and an opening formed through the pocket to allow the jack pad to be accessible from outside the jack pad holding device, wherein the coupler housing includes a plurality of coupling member portions that extend outwardly from the jack pad holder portion, wherein the plurality of coupling member portions includes a first pair of coupling member portions extending laterally outward from the jack pad holder portion in generally opposite directions, and wherein the opening is an enlarged opening including lateral opening portions that extend laterally outward from the jack pad holder portion correspondingly towards the first pair of coupling member portions; and
a plurality of coupling elements coupled to the coupler housing and configured to couple to the aircraft, and wherein the coupling elements are correspondingly coupled to the coupling member portions.

2. The jack pad holding device of claim 1 , wherein the jack pad holder portion has a pocket sidewall defining the pocket that is sized to substantially match a base portion of the jack pad.

3. The jack pad holding device of claim 2 , wherein the pocket is sized to define a nominal gap of from about 0.02 to about 0.1 mm between the base portion of the jack pad and the pocket sidewall.

4. The jack pad holding device of claim 2 , wherein the jack pad holder portion has a lip that extends from the pocket sidewall towards the opening to facilitate retaining the jack pad in the coupler housing.

5. The jack pad holding device of claim 1 , wherein the opening has a diameter of from about 25 to about 75 mm to facilitate accessing the jack pad from outside the jack pad holding device.

6. The jack pad holding device of claim 1 , further comprising a plurality of threaded fasteners that correspondingly attach the coupling elements to the coupling member portions of the coupler housing.

7. The jack pad holding device of claim 1 , wherein the coupling elements are configured as suction cups that are coupled to the coupling member portions and that have cups correspondingly facing in directions opposite the coupling member portions for coupling to the aircraft.

8. A jack pad holding device for supporting a jack pad to an aircraft, the jack pad holding device comprising:
a coupler housing configured for holding the jack pad, wherein the coupler housing includes a jack pad holder portion having a pocket formed therein for holding the jack pad and an opening formed through the pocket to allow the jack pad to be accessible from outside the jack pad holding device, wherein the coupler housing includes a plurality of coupling member portions that extend outwardly from the jack pad holder portion, wherein the plurality of coupling member portions includes a first pair of coupling member portions extending laterally outward from the jack pad holder portion in generally opposite directions; and
a plurality of coupling elements coupled to the coupler housing and configured to couple to the aircraft, wherein the coupling elements are correspondingly coupled to the coupling member portions, wherein the first pair of coupling member portions have coupling element mounting surfaces that correspondingly support the coupling elements and that are tilted inwardly generally towards each other at angles of from about 2° to about 6°.

9. The jack pad holding device of claim 1 , wherein the plurality of coupling member portions includes a second pair of coupling member portions extending outward from the jack pad holder portion in generally rearward directions.

10. The jack pad holding device of claim 9 , wherein the second pair of coupling member portions have coupling element mounting surfaces that correspondingly support the coupling elements and that are tilted inward generally towards each other at angles of from about 1° to about 3°.

11. The jack pad holding device of claim 1 , wherein the jack pad holder portion has a pocket sidewall that defines the pocket and that has a forward section that defines a relief adjacent to the pocket.

12. A method for jacking an aircraft, the method comprising the steps of:
positioning a jack pad adjacent to the aircraft;
disposing the jack pad in a jack pad holding device, wherein the jack pad holding device comprises a coupler housing including a jack pad holder portion having a pocket formed therein, and wherein disposing the jack pad in the jack pad holding device further comprises disposing the jack pad in the pocket of the coupler housing, wherein the jack pad holder portion has an opening formed through the pocket, and wherein disposing the jack pad in the jack pad holding device further comprises positioning the jack pad in the pocket of the coupler housing with a jack engagement portion of the jack pad extending through the opening and outside of the jack pad holding device;
coupling the jack pad holding device to the aircraft to support the jack pad to the aircraft; and
moving the jack pad with a jacking device to jack the aircraft.

13. The method of claim 12 , wherein the jack pad holding device comprises a plurality of coupling elements coupled to the coupler housing, and wherein coupling the jack pad holding device to the aircraft comprises coupling the coupling elements to the aircraft.

14. The method of claim 13 , wherein the coupling elements are configured as suction cups having cups, and wherein coupling the jack pad holding device to the aircraft comprises depressing the cups against the aircraft to couple the suction cups to the aircraft.
