Abstract

A load support is arranged to be connected to a parachute and has a center guide tube slidably receiving a landing rod. This landing rod is of a sufficient length to project beyond the lower end of the guide tube so as to engage the ground ahead of the load support. A slidable friction connection is provided between the landing rod and the load support for cushioning the landing shock of such support. Brake pads are used as the friction connection, and such brake pads are associated with adjustment apparatus comprising a rotatable holder for the brake pads and a cam and cam follower assembly which serves to adjust the compression of the brake pads on the rod upon rotation of the holder. A pinion and gear connection is provided between the holder and the support to provide the rotatable adjustment.

Claims

1. A shock absorbing mechanism for a parachute supported load comprising

(a) a load support container having enclosing sides and also having top and bottom wall portions,

(b) connecting means on said container arranged to connect it to a parachute,

(c) tube-like guide means integral with said container,

(d) said guide means being disposed in a central portion of said container and opening through said top and bottom wall portions,

(e) a landing rod slidable in said guide means,

(f) and friction brake means operating between said landing rod and said guide means,

(g) said landing rod being of a sufficient length to project beyond the lower end of said container whereby said landing rod in a parachute landing of said container engages the ground prior to the container and frictionally slides upwardly through said container in said guide means for cushioning the landing shock of said support means.

2. The shock absorbing mechanism of claim 1 wherein said friction means comprises brake pads mounted on said container and engageable with the surfaces of said rod.

3. The shock absorbing mechanism of claim 1 wherein said friction brake means comprises brake pads mounted on said container and engageable with the surfaces of said rod, and adjustment means on said friction means for adjusting the compression of said pads on said rod.

4. The shock absorbing mechanism of claim 3 comprising a rotatable holder for said brake pads, and cam and cam follower adjusting means on said holder and brake pads serving to adjust the compression of said brakes on said rod upon rotation of said holder.

5. The shock absorbing mechanism of claim 3 comprising a rotatable holder for said brake pads, cam and cam follower adjustment means on said holder and brake pads serving to adjust the compression of said brakes on said rod upon rotation of said holder, said adjustment means including a pinion and gear connection between said holder and said support.
