FIG. 6 is a detailed view of the mechanism for releasably securing the seats together when in their stowed positions.
Description of preferred embodiment Turning now to the drawings in greater detail, FIG. 1 shows an air-ground rescue device constructed in accordance with the present invention, and including a protective shield assembly having one panel overlying the back portion of a person to be rescued so as to protect him as the helicopter hoist cable 10* raises the entire device upwardly through overhanging tree branches or the like.
The rescue seat portion of the device may be of conventional design, as for example that described in a copending application of Greenberg et a1, entitled Air Sea- Rescue Device With Flotation Collar, filed June 21, 1967 under Serial No. 647,647 and assigned to the assignee herein. As described therein and as shown herein, a set of three foldable seats 12, 12 are hingedly mounted adjacent the lower end of the rescue device and each of these is movable from an extended position to a folded position shown. The upper portion of the rescue seat comprises an elongated shank portion terminating in an eye 14 which can be received on the helicopter hoist cable hook which hook preferably is of the full swivel type and includes a cylindrical bearing portion as shown at 16. Finally, the upper portion of the rescue seat includes a fabric envelope in which a plurality of safety straps 18, 18v are provided for securing an unconscious person to be rescued to the device, or simply to serve as a safety strap for the person being rescued as shown in FIG. 1.
In accordance with the present invention, a protective shield assembly is provided on the cable 10, in spaced relation above the rescue seat portion just described, in order to protect the person being rescued from overhanging tree branches or the like. As shown the shield assembly comprises a pair of clam-shell type panels 20, 20 each of which is hingedly connected at its upper end to a cap 22, which cap can be releasable secured to the cable 10 in a manner to be described. The panels 20, 20 are preferably formed of transparent plastic material into the clam-shell shape shown in FIGS. 1 and 2. It is an important feature of the present invention that the panels 20, 20 can be releasably secured in their stowed positions wherein the corresponding side edges of said panels are arranged in contiguous relation to one another to facilitate lowering of the entire device downwardly through overhanging tree 'branches or the like. Means is provided for releasably retaining the panels 20, 20 in the stowed position and, preferably, said means comprises an elastic cord 24 which is adapted to encircle the lower flanged edges of the panels as best shown in FIG. 6. The elastic cord 24 can be conveniently removed from one of the panels at the time a seat 12 is lowered by pushing a clip 25- downwardly to expand the cord 24 slightly so that it drops off the lower flanged edge of the panel 20. A retaining cord 23 prevents loss of the clip 25 following release of the panel 20 as described.
As shown to best advantage in FIG. 2, the conically shaped cap 22 has a laterally open side slot 28 for receiving the suspended cable 10. This slot 28 is also shown in FIG. 3, wherein the cap 22 is shown in plan view with the cable 10 being shown in section in generally centered relation with respect to the cap 22. A pivotally mounted lever 30 is provided in the cap 22 for movement about an axis defined by pivot pin 48 and the lever 30 is pro- VldCd in a recess 34 defined for this purpose in the cap 22 generally opposite to the laterally open side slot 28 for receiving the cable 10. The lever 30 not only provides a convenient handle with which the shield assembly can be positioned on the cable 10, but also serves when moved to the position shown in FIGS. 4 and 3 to actuate a pair of cable clamping paws (to be described) for removably mounting the shield assembly to the cable 10.
As best shown in FIG. 2, each of the panels 20, 20 is movable from the stowed position shown in full lines to the broken line position indicated for the left-hand panel. Each panel is hingedly connected to the cap 22 by a short straight hinge 38 of conventional design having one side connected to the inside of the panel and the other side connected to the inside of the cap as shown in FIG. 5. In the raised position wherein the panel 20 is arranged at substantially 90 to the cable 10, it will be apparent that a person to be rescued can readily position himself on the seat 12 for rescue.
The panels 20, 20 can be releasably held in the raised position shown in FIG. 2 by a pair of channel shaped brackets 36, 36 having detents 40, 40 in the leg portions thereof for releasably engaging protrusions 39, 39 on brackets 41, 41 carried by the cap 22. Each channel bracket 36 is mounted at one end on a rod 37, which rod has its ends mounted to an associated panel 20 as shown in FIGS. 4 and 5.
Turning now to FIGS. 4 and in greater detail, the conically shaped cap 22 comprises the upper port-ion of the shield assembly and includes a laterally extending web member 42 provided for stiffening the cap in the plane defined by the two hinges 38, 38 associated with the panels 20, 20. The cap structure is further strengthened by an inverted U-shaped housing 44 which is carried by the web member 42 and which serves as a fixed structure for pivotally supporting the lever 30. The lever 30 is pivotally supported for movement about a fixed axis defined by the pivot pin 48 mounted on the upper portion of the inverted U-shaped housing 44.
The operating lever 30 includes a crank arm portion 56 which extends inwardly toward the cable and carries a link 58 having two right angle bends therein which define offset leg portions. The lower leg portion thereof is received in an arm 50 provided at the midpoint of an oscillatable tubular member 62. From FIG. 3, it can be seen that pivotal movement of the lever 30 serves to oscillate the tubular member 62 on its own axis. The tubular member 62 also carries a pair of clamping jaws 60 and 61 at its upper and lower ends respectively, and these jaws thus pivot on the axis of the member 62 so as to releasably clamp the cable 10 against the inner edge of the slot 28 in the cap 22. The upper jaw 60 is shown in FIG. 3 in clamping position against the cable 10. An outwardly extending finger portion 63 moves across the slot 28 to trap the cable 10 therein in response to downward pivotal movement of the lever 30. In the clamped position shown, the crank arm portion 56 of the lever 30 moves overcenter in order to hold the clamping jaws 60 and 61 against the cable 10. The upper jaw 60 preferably is located adjacent the U-shaped housing 44, which housing has a slot against which the jaw can urge the cable 10. Similarly, the lower jaw 61 is preferably located adjacent the web 42, which web also defines a slot for receiving the cable 10.
In operating the above-described device, a crewman aboard the rescue helicopter would first position the rescue seat on the hook provided at the lower end of the helicopter hoist cable. The crewman would then position the shield assembly on the cable by sliding the cable through the opening 28 provided for this purpose in the cap and lowering the shield assembly so that a spacer 52 on the underside of the web 42 engages the upper portion of the cylindrical bearing provided on the helicopter hoist cable. He would then secure the panels with the clastic cord 24 adjacent their lower edge portions as described herelnabove. The crewman would then lower the entire assembly downwardly through overhanging tree branches, or other obstructions, to an awaiting person to be rescued. The latter person would pull one of the seats, as for example the seat 12 shown in broken lines in FIG. 2 and remove the cord 24 so that he could lift one of the panels, as for example the panel 20 shown at approximately right angles to the cable 10 in FIG. 2. The person to be rescued would then position himself on the seat and lower the panel 20 to an intermediate position wherein the panel would overlie his back as shown in FIG. 1, at which time he would be ready to be hoisted by the crewman aboard the helicopter. The crewman would then raise the entire assembly with the person on board as depicted in FIG. 1 up to the helicopter. In most cases, the crewman aboard the helicopter would remove the shield upon manipulation of the lever 30 and then hoist the person being rescued to a proper level for permitting said person to gain access to the interior of the helicopter. This last step is a necessary one in most instances because the helicopter hoist mechanism would not permit raising of the entire assembly to a proper height for permitting the rescued person to remove himself from the device without first removing the shield assembly. Thus, it is an important feature of the present invention that the shield assembly itself can be conveniently or easily mounted or removed from the hoist cable. Also, in this vein, it should be noted that the rescue seat device can be used either with or without the shield assembly described herein, depending upon the terrain conditions with which the helicopter rescue crew is confronted in an individual situation.
