Tony R. Sowder BY United States 2,710,650 Patented June 14, 1955 due AERIAL SKI LIFT CHAIR Tony R. Sowder, Spokane, Wash, assignor to Riblet Tramway Company, Spokane, Wasl1., a corporation of Washington Application March 19, 1954, Serial No. 417,327 8 Claims. or. 155-189 This invention relates to aerial ski chair lifts and in particular to improvements in the chairs for such lifts.

It is common practice to employ on aerial ski lifts chairs which are provided with footrests. The footrests are either fixed in position or they are movable out of operating position for the loading and unloading of passengers and into operating position for supporting the skis of passengers.

When the foot rest is of the fixed ppsition type, it is difficult for the passengers to mount the chairs and always presents a possibility of the expectant passenger being struck thereby. They also provide difficulty in alighting from the chairs, making it awkward to remove the skis from the footrests in preparation of dismounting the chair.

In the well known movable footrest type, conventionally it requires an attendant to position the footrest either before the passenger mounts the chair or after his having alighted therefrom or both and also the footrests are provided with means for supporting the skis which interfere with free movement of the passenger when mounting or alighting from the chair. It is also conventional to provide a hand rail or similar mechanism which may be grasped by the passenger of a chair, the purpose of which is to confine the passenger against accidental displacement from the chair and in some cases to permit the passenger to operate the footrest.

In every structure of which I am aware, this hand rail is pivotmly secured to the chair and is either movable in a horizontal plane away from the passenger and forwardly of the chair or it swings in an arc upwardly about an axis extending laterally of the chair. Unexpected irregular movements of the ski lift cause the passengers to be thrown forwardly at times and pressure upon these hand rails causes them to open, thus ejecting the passenger. In some instances, when passing over depressions in the earths surface, the passengers have been seriously injured because of falls from relatively great heights.

Therefore, one object of the invention lies in the provision of a ski lift chair which has a hand rail designed to preclude accidental displacement of passengers from the chairs.

Another object of the invention lies in the provision of a ski lift which has a retractable foot rest.

Another object of the invention lies in the provision of a ski lift chair having a retractable foot rest and a vertically tiltable hand rail operably connected together so that when the hand rail is moved from its confining position, the foot rest is moved to an inoperative position.

Another object of the invention lies in the provision of a ski lift chair in which the foot rest is normally held out of the way for loading and discharging passengers but which can be brought by the passenger into either the operative or inoperative position.

According to the present invention, I have provided in an aerial ski lift, a lift chair having a dependent longitudinally swingable foot rest and means operable by the passenger riding in the chair to move the footrest from an operative ski supporting position to an inoperative position where it is disposed substantially to the rear of the chair seat. These and other objects of the invention will become apparent during the course of the following description and drawing wherein a preferred form of the invention is disclosed. It should be understood however that the drawing and description are illustrative only and are not intended to limit the invention except insofar as it is limited by the appended claims.

In the drawing:

Figure 1 is a perspective view of a ski lift chair embodying my present invention;

Figure 2 is a side elevation of the chair shown in Figure Figure 3 is a front elevation of the ski lift chair;

Figure 4 is a skeletal perspective view showing the lower end of the footrest shank; and

Figure 5 is an exploded perspective view of a footrest connection.

The essential features of the invention can be understood by reference to the drawings in which the numeral 10 designates the improved ski lift chair having a dual passenger occupancy chair supported intermediate its length by means of a hanger element 11 which is welded or otherwise secured to the chair 10 and extends upwardly to a point Where it is secured to cable ways (not shown) of an aerial ski lift. As indicated, the chair is provided with a seat 12, preferably formed of slats, and a backrest portion 13 and is constructed and arranged to receive and support two passengers.

The hanger 11 is rearwardly braced by means of a rod 14 and forwardly by means of a fiat bar bracket 15 constituting an element of the chair.

A pair of hand rails or arms 16 are journaled on the bracket 15 on spaced parallel horizontal axes extending forwardly of the chair and which secure the arms 16 for vertical tilting movement transversely of the seat from a horizontal position spaced substantially above the front edge of the seat to an upright position at the edge of the seat and adjacent to the hanger 11. A spring clip 17 is secured to the hanger 11 and is adapted to yieldably secure the arms 16 in their vertical positions.

Pivotally connected to the arms 16 at points removed from the journals 16' I provide depending links 18 which are adjustable in length and have their lower ends each pivotally connected to a toggle joint 19 having its forward end pivotally connected to a pendulous footrest 20 and its rearward end pivotally connected at a fixed location relative to the chair 10. It will thus be seen that as the arm 16 is tilted upwardly from its horizontal position the link 18 is drawn upwardly thus breaking the toggle joint 19 and moving the footrest 20 from its forwardly extending operative position shown in full line of Figure 4 to its inoperative position shown in dotted lines of Figure 4.

In Figures 1, 2, and 3, the arm 16 and footrest 20 for the left side of the chair 10 are shown to be in the inoperative position while those of the right side of the chair are shown to be in the operative position.

Each footrest 20 is provided with an inverted L-shaped leg 21 having its base portion 22 extending horizontally through one sleeve 23 carried by the chair 10 at the front edge of the seat 12 and thereunder and hingedly connecting the footrest 2G to the chair It) for forward and rearward swinging movement of the shank 24 about the axis of its base 22. The forward end of each toggle joint 19 is pivotally secured to the shank 24 of the footrest 21 at a point removed from the axis of the base 22 and therefore as the arm 16 is tilted upwardly the toggle joint 19 is broken and the footrest 20 is caused to swing rearwardly to an inoperative position.

At its lower end the tubular shank 24 is provided with a semicylindrical extension 25 which cooperates with an extension 27 formed on a sleeve 28 and comprising approximately 90 of a cylinder. The extensions 25 and 27 are positioned in the recesses defined by the extension of the opposed element and are pivotally united by means of a journal pin 29 having an enlarged head 30 and adapted to extend through the sleeve 28 and be secured by means of a rivet or bolt 29 extending through the aligned apertures 31 and 32 in the pin 29 and shank 24 respectively. It will thus be seen that the sleeve 23 is mounted for rotation about 90 of a circle coaxially with the shank 24.

A ski support bar 33 formed of a substantially U-shaped element is welded to the sleeve 28 to extend radially therefrom and provides a bar upon which the skis of a passenger may be placed while riding in the chair It). To protect the skis I cover the bars 33 with a tubular rubber sheath 34. The extensions 25 and 27 cooperate to position the ski support bars 33 in a hori zontal position spaced from and parallel to the base portion 22 of the leg 21 when the footrest is disposed in its operative position and from this position each ski support bar 33 is permitted rotation about the axis of the shank 24 forwardly to a position parallel with the plane of movement of the chair in the ski lift. This movement is of no consequence under operative condi tions, but when it is desired to dismount from the chair the arm 16 is raised whereby the footrest 20 is moved to the inoperative position and by gravity the ski support bar 33 is moved to the plane parallel with the movement of the chair 10. It will thus be seen that the ski support bar 33 drops away from under the skis worn by the passenger of the chair and pivots forwardly and downwardly to prevent interference with the skis of the passenger mounting or alighting from the chair.

Having thus described my invention. I claim:
