Patented Dec. 21, 1943 ADJUSTABLE FOOTREST Fred G. Cassens, Jennings, and William J. Roa, University City, Mo., assignors to American Car and Foundry Company, New York, N. Y., a corporation of New Jersey Application August 3, 1940, Serial No. 350,412

3 Claims. (01. 155-172) This invention relates to foot rests in general and in particular to foot rests for use on railway car seats of the revolving type.

In revolving seats as previously built attempts have been made to attach the foot rest to the revolving seat portion in order to get the foot rest at the proper position for comfort but such a placement of the foot rest required complicated mechanism, permitting folding of the rest automatically as the seat revolved. It is an object, therefore, of the present invention to provide a. foot rest for revolving seats, which foot rest is of extremely simple construction and carried by the seat base or support structure.

Another object of the invention is the provision of individual foot rests for dual type revolving seats and which foot rests are independently adjusted.

A still further object of the invention is the provision of a simplified type of foot rest which may be moved to various positions and held locked in such positions by a bayonet type catch.

These and other objects of the invention will be apparent to persons skilled in the art from a study of the following description and accompanying drawings, in which:

Figure 1 is a side view of a portion of adjoining seats with the improved foot rest applied thereto;

Fig. 2 is a front view of the foot rests applied to the seat base frame 02" pedestal structure;

Fig. 3 is a plan view of the pedestal or seat frame assembly with parts of the foot rest mechanism broken away to better disclose the construction;

Fig. 4 is a partial sectional view of the improved latch;

Fig. 5 is a detail view of one end of the latch disclosing the cam construction;

Fig. 6 is a detail sectional view showing the manner in which the foot rest is mounted in the pivoted side arms;

Fig. 7 is an enlarged detail view showing the relation of parts with the latch in released position;

Fig. 8 is a sectional view taken on line 8-8 of Fig. '7, and

Fig. 9 is an enlarged perspective view of the arm carried cam member.

Referring now to the drawings in detail, it will be seen that the seat is formed with side pieces A which are pivoted to back B and between which is mounted the seat cushion C. This entire seat is mounted on a rigid frame D (Fig. 2) and is revolvably supported upon a base F. The base thetic resilient material.

for supporting the seat consists of a metal framework 2 supported at its outer end on seat pedestal 4 and at its inner end by means of angle clip 6 upon some element of the car or vehicle structure. The base structure side members have connected thereto a plurality of brackets 8 located adjacent the inner, outer and intermediate portions of the base and each of these brackets is formed with an opening for reception of a pivot bolt or other means l0. Each of the brackets extends outwardly beyond the pivot connection and is flared to receive a plurality of openings l2 by means of which the angular position of the foot rest may be controlled. There are two foot rests connected to the seat base on either side thereof but since they are identical in construction, the description of one will suffice for all of the foot rests. Each foot rest consists of a pair of side arms i4 pivoted to the brackets by pivot bolts or other means in previously referred to and carrying at their outer ends foot rest it. The foot rest proper in the present instance isof tubular form and comprises an inner member I8 carrying an outer resilient member 20 formed of rubber or other natural or syn- The inner member is internally threaded at the ends to receive a plug 22 by means of which the foot rest proper may be rotatably mounted in the side arms.

In order to control the position of the side arms and hence of the foot rest proper, a bayonet type latch is provided and this consists of a pair of rods 3i) having tapered noses 32 and having secured to the rod portion adjacent the nose, as by welding, a V-shaped cam 34. Each cam has attached thereto, or formed as integral parts thereof, outstanding ears 38 located in alignment with the apex of the V-shaped cam surfaces. One of the rods has welded thereto as at 33 a tube iii, the other end of which is adapted to sliclably engage the inner end of the other latch rod. The inner ends of the two latch rods are located within the tube and spaced apart by means of a compression spring 42 constantly urging the latch rods apart. The latch rods are connected together for sliding movement by means of a bolt 44 engaged in one of the latch rods and extending through a slot 48 formed in the tubular member 40. Thus it will be seen that the latch rods are joined together to form an assembly which must rotate in unison yet in which the latch rods may move toward or away from each other; in other words, along the axis of the assembly. Rotation of the entire assembly may be accomplished by applying pressure to a projection 50 welded or otherwise secured to one of the latch rods in such a position as to be readily accessible to the operator. In order to cause retraction of the latch rods, a cam member 52 is welded or otherwise secured to the inner surfaces of the foot rest side arms. Each of these cam members is formed with a central opening 54 located in alignment with a similar opening in the side arms and at such a position as to register with the holes i2 in the base brackets. The cam member is also formed with V-shaped cam surfaces 53 and with spaced outstanding lugs 58 adapted to contact earstdon thelatchrods and limit the rotation thereof. It will be seen that when the cam surfaces of the iatch'rods and of the side arms are engaged with the apices in engagement, the nose portion of the latch rods will be in engagement with the aligned hole it in the base bracket. Pressure applied to member 59 will cause a rotation of the entire latch assembly causing the inclined surfaces of thecam members on the latch rods and side arms to force the latch rods inwardly compressing the spring and removing the latch rods from engagement with the holes l2in the base brackets. Excessive rotation of the latch'rods is prevented by engagement of ears 3% and lugs 58; It will be seen that the latch rod may be rotated in either direction from its normal position, thus by applying pressure to the releasing member 5!] in the proper direction, the foot rest will be moved in the desired direction by the same force that causes a retraction of the latches; It will be apparent also that pressure may be applied by one toe of the operator resting on operating member 56, while pressure may be applied by the other toe of the operator acting upon the foot rest proper toeither raise or lower the same to a new position;

While the improved'foot rest has been described more or less in detail, it will be obvious to persons skilled in the art that various modificationsand rearrangements of parts may be made and'all such modifications and rearrangements ofparts are contemplated'as will fall within the scope of the appended claims defining means extending between said side arms and rotatable relative thereto and including a tubular portion and locking pins non-rotatably carried by said tubular portion with at least one of said locking pins being mounted within the tubular portion and slidable longitudinally thereof, said locking pins extending beyond said tubular portion and through said side arms into locking engagement with said brackets to control the positions of said side arms and foot rest.

2. An adjustable foot rest assembly carried by a seat base frame and comprising, brackets secured to the base frame and extending laterally thereof, side arms pivotally mounted on said brackets inwardly of the outer ends thereof, a foot rest. carried by the side arms adjacent the ends remote from the pivotal mount, locking means extending between said side arms and rotatable relative thereto and including a tubular portion and locking pins non-rotatably carried by said tubular portion with at least one of said locking pins being mounted within the tubular portion and slidable longitudinally thereof, said locking pins extending beyond said tubular portions and through said side arms into locking engagement with said brackets to control the positions of said side arms and foot rest, and cam means secured to said side arms and locking pins and operable upon rotation of said tubular portion to cause retraction of said pins out of locking engagement with said brackets.

3. An adjustable foot rest assembly carried by a seat base frame and comprising, brackets secured to the base frame and extending laterally thereof, side arms pivotally mounted on said brackets inwardly of the outer ends thereof, a foot rest carried by the side arms adjacent the ends remote from the pivotal mount, means secured to the side arms intermediate the pivotal mount thereof and the foot rest, locking means extending between said side arms and wholly carried thereby, said locking means comprising in part a pair of locking pins slidable laterally with respect to said first named means and side arms and normally extending inte locking engagement with said bracketsv to control the pivotal movement of the side arms and foot rest, said locking pins engaging said first named means to cause lateral sliding movement of the locking pins relative to saidside arms and out of engagement with said brackets upon rotation of said locking means.
