3 Claims.
This invention relates to loading ramps, and relates more particularly to a novel arrangement to facilitate the loading and unloading of passengers on commercial airplanes.
An importantobject of the invention is the provision of an improved passenger handling apparatus provided with plural ramps, one for loading and the other for unloading of passengers, the apparatus having means for quickly adjusting the height of the outer end to the height of the plane door. A cab at such exit end is arranged to be raised and lowered by hydraulic or other lifting means, and when in its lowered position it occupies a position low enough to enable the tail section of all but the smallest transport planes to pass thereover. The ramps at their outer ends are pivotally joined. to such cab, and are raised and lowered Withthe cab. The opposite ends of the ramps are positioned within a xed housing having two levels. Thus, the emplaning ramp may lead from the higher level, and the deplaning ramp lead to the lower level. This arrangement effectively separates the oppositely-moving passengers and permits the plane to be unloaded and loaded in a minimum of time.
Another object of the inventionn is to provide a loading ramp of the character described wherein the cab at the outer ends of the ramp will be provided with a slidable extension which, when the cab is raised to proper height, will be moved outwardly to contact the fuselage of the plane adjacent to the door, and wherein the outer edges of the extension are yieldable to enable such outer edges to conform to the contour of the fuselage. In this fashion the passengers will be protected from wind, rain and snow.
The apparatus of the present invention, in addition to speeding up the process of emplaning and deplaning, also oiers a greater measure of safety and comfort to passengers than do the portable steps currently in use.
In the drawing:
Fig. 1 is a side elevation of a loading ramp embodying the present invention, the view showing th'e loading and unloading ramps in elevated position.
Fig. 2 is a top plan view of the structure shown in Fig. l.
Fig. 3 is a broken vertical section taken on line 3-3 of Fig. 2.
Fig. 4 is a transverse vertical section taken on line 4-4 of Fig. 1.
Fig. 5 is a broken plan view showing the extensible floor arrangement.
The structure of the present invention may include a cab I0, an emplaning ramp I I, a deplaning ramp I2, an upper housing section I3, and a lower housing section I4. The cab is provided with a lower wall I5, side walls I6 which may be provided with windows I'I, and an upper wall I8. It is arranged to be raised and lowered by means of a vertical hydraulic ram 2I, or other suitable means, which is suitably mounted within an opening 22 in the ground, the level of which is shown at 23. No means for operating the ram are shown in the drawing, although any conventional means may be employed for this purpose.
The cab is open at its outer end and receives a generally rectangular housing 24 which is slidable inwardly and outwardly of the cab. At its outer end, extendable housing 24 is formed with telescopic or compressible wall sections 25 which permit the edges 2B to closely t the contour of the fuselage 21 of a plane. These walls may further be provided with intermediate telescopic section 28. Thus, when the plane has been moved to loading position and the cab raised to proper level, as shown in Fig. l, suitable means (not shown) may be provided` for moving the housing 24 outwardly to engagement with the door opening in the side wall of the fuselage, and the telescopic section 28 retains the edges 26 in relatively firm engagement with the side walls of the fuselage to protect passengers from rain, etc.
Housing section I3 has a floor level, indicated at 32, which is higher than the oor level 33 of housing section I4, the latter level being preferably a few feet above the ground level to allow for baggage conveyors underneath. Ramps II and I2 are of substantially similar construction and are provided with lower walls 35, upper walls 36, and side walls 31 which may have a number of windows 38 therein.
Referring particularly to lower ramp I2 which is shown in some detail in Fig. 3, it will be noted that upper wall 3B has a forward extension 42. which projects inwardly of upper wall I8 of the cab I0. Lower wall 35 is pivotally secured, as at 43, to the lower wall I5 of the cab. Thus, as the cab is lowered the forward extension 42 projects further inwardly of the cab, and conversely, when the cab is raised, it moves outwardly. At its opposite end, lower ramp I2 is pivotally connected as at 45 with an extensible oor section 46 composed of a plurality of spaced, longitudinally-disposed spaced members which are interposed between the fixed, spaced floor members 4l secured on the lower wall 48 of such section. The upper wall 36 likewise has an inner extension 49 which projects inwardly of the upper wall 50 of housing section I4.
As the cab is raised and lowered, there will, of course, be an appreciable amount of outward and 'inward movement of the lower wall 35 of ramp I2. The same is true of ramp II. Suitable co-ntrol means are indicated at 53 within the cab for raising and lowering the ram. This arrangement permits of safer handling than would be the case otherwise.
The upper 4wall X35 of one =of `the Yramps may be provided with a vconduit 5f! `within which may be positioned wires for telephone and other utilities leading to the plane, and an air-conditioning conduit for the plane may also be positioned there.
Although not illustrated inthe drawing, the extension housing for the cab may be provided with the same type of extensiblerlooring as shown at 46-4'1 at the opposite ends of the ramps.
It will be appreciated from the foregoing that a most convenient arrangement for the emplaning :and deplaning of passengers has been 'provided. By the two-level housing at the inner kends Yo'f the ramps both classes of passengers al- Ways walk down an inclined surface, they are always protected from `the elements, and the time required for passenger 'leading is greatly de- Lcrea'sed.
'While vone form or embodiment of the 'invention has been shown and-described herein Vfor illustrative purposes, and the vconstruction vand yarrangement incidentalto Ia specic application "detail, it is to be understood that the invention is 'limited neither to the mere details or relative arrangement of parts, nor to its specific embodiment shown herein, but 'thatefitensive deviations the outer lends -of the ramps, means for raising 'e such cab to an adjusted, iixedposition, aslida-ble extension housing at the outer `end'of such cab, the outer terminals of the lower walls of the ramps being pivotally connected with 1the Vinner end of `the cab, a 'housing having plural levels and openings on lsuch levels receiving the inner terminals of the ramps, 'an extensible floor section 'comprising plural spaced Vfloor members fixed to the 'housing'floor 'and plural spaced 'oor members disposed between the xed members 'in sliding relation thereto, and pivotal means securing the sliding oor members rto the inner terminals of the ramps.
