12 claims. (c1. 15s-171)A This invention relates to chairandv legrest combinations and more particularly to upholstered chairs having leg rests which stow beneath the chair seats. In one aspect this inventionrelates to novel'suspensionimechanism and sitowage arrangements for leg rests'by'means ofwhich the leg rest may be elevated from a stowed position under an upholstered chair to the level of' the chair seat without being inconveniently near the iioor to reach in the stowed position and without sacrificing critical cushioning space within the chair seat.l In another aspect, thisinvention relates tor novelllsuspension mechanism for leg rests used with'railroad car chairs or the like by means of which the leg rest may be elevated to a position free and clear ofthe chair frame for purposes of rotating the said chairs.

One of the principal difficulties nin designing leg rests for railroad car chairs'or the'like is the provision of adequate space for the leg rests.` Generally speaking, the spacing between railroad l car ychairs is suflicient kto provide knee and leg room, but not to accommodatev leg rest mechanism as well.

Various attempts have been made in the pastl to devise satisfactory leg rests-for this purpose, but hitherto none have vmetvwith any appreciable success. One attempt involved stowing a legrrest in a recess inthe back ofea'ch chair for use by the person sitting nefitbehind. Such a 'leg rest,

however, takes up' vital knee. room'when in the" stowed position; and toraiseor lower it, inevitably shakes the chair ahead; disturbing the occupant.

This design has the additional 'disadvantageof consuming-space inithe chair back which might otherwise be used for-back cushioning.

Another type of leg rest developed in the pastslides directly into lthe cushion box of the-v chair seat Vand may` be pulled vforward for use. The

principal disadvantage of -this latter type oileg rest is that itl takes up lspace lwithin the seatcushion which would'otherwisebe available for springs, andtherefore the cushion does not have the depth or resiliency desired.

`Leg rests which drop downand fold under thechair seat have also been used in the past, but` in the case of upholstered furniture having any substantial seat depth, it is difculttoconstruct leg rests which can be conveniently pulled up to the level of the chair seat and still be stowed under the chair without taking up vital spring room. In the past such leg rests have had to be` so near the floor that reaching for them has been inconvenient or else it has been necessary to tip thechair seat up to pull them out. This latter 2 type isobviusly inconvenient las well as'being impossible to use in railroad cars or other public' seating arrangements:y e

Another disadvantagefin legl rests which fold underneath-the seat', particularly applicable to railroad car seatsy-is'that theyxinterfere with rotating the chairior the purpose of facing in the opposite direction. In general. hitherto known leg rests for car seats and thelikef have'alsobeen expensive to manufacture. In"l ordertof-provide mechanism for elevatingy themv -to'the'chair seat level they have generally employed numerous moving parts also renderin'gl'themdiflicult to keep clean and maintain-inf proper working-condition It 'is anobje'ctof our invention to provide a l tilting thechairupward.y v t An additionalobject'of our invention is to provide -a-leg restfor the-railroad car chair or the like which may bestowed beneaththe chair seat,`

elevated to a leg restV position convenient for use by the chair occupantv and whichfmay be further 4elevated to a'position'r above the chair seat'where it will not interfere withthe'r'otating of the chair. It is-a further object: of'ourinvention to provide means for-securing such aleg rest in the said position above the'chair seat so that the chair may be` rotated/without danger ofthe leg rest dropping during the-rotating operation;

4It is an additional lobject of our invention to provide means `for'preventing the leg rest from droppingsharply` froml its uppermost position to the stowed position beneath the seat, and to provide other means for-holding the legrest in the stowed position under the seat.

In. the accomplishment of these objects, we

employ an "upholstered" 'chair cushioned in the seat area by inner springsandv a' thick top layer of foam rubber. Near the front of the cushioned seat-we provide fa pairi'of pivot bearings, one

at each side within the `seat frame near the top.`

The leg rest-"is pivotally. mountedI on these bearings -for rotationfin frontfoi'the' chairI seat from a position substantially above the seat to a stowed position partly within a recess in the lower forward part of the seat and partly under the seat. The leg rest comprises an upper, calf rest section pivotally connected to a lower, heel rest section, and when set up as a leg rest, slopes forward from the chair seat. To stow the leg rest merely requires lifting the calf restsection high enough to allow the heel rest to pivot backward, pivoting it backward, and then depressing the calf rest until both sections of the leg rest have reached the stowed position under Vthe chair.

It is a feature of our invention that the lower I forward corner of the seat cushiony box is recessed to receive the upper part ofthe calf rest in the stowed position, and that an intermediate spring supporting structure is providedbetween the two leg rest bearings. Thus; the calf rest is not too low to be conveniently reached by the chair occupant while at the same time vital cushioning across thefront of the seat has not been lost.- i

It is an additional feature of our invention that, although the leg rest is partially housed in the lower forward part of the seat cushion box. the full depth of the central part of the cushion box is available for inner springs andcushioning. A .n

A further feature of our inventionis a simple locking means for maintaining the leg rest in a position above the seat cushion forpurposes of rotating the chair and clearing underneath the chair. The lock serves to secure the lower, heel rest portion of the leg rest to the upper, calf rest portion when the latteris in the fully elevated position above the seat, such that the bottom of the heel rest portion abuts against the bottom of the seat preventing the leg rest from pivoting to a lower position. ,l

An additional feature of our invention lies in the use of two spring retarders disposed to intercept the path of each of the pivot ,links which connect the leg rest to the pivot bearings. O ne retarder prevents the leg rest vfrom dropping sharply from the chair pivot position, and the other retains the leg rest in thestowedposition.

It is an additional feature of our inventionA that we provide a pair of wheels,-one on each side of the lower corners of theheelrest for the purpose of allowing smooth movement of the heel rest along the floor into the stowed position,l

and to prevent marring the iioor.

Further objects and features of our invention will best be understood and appreciated from a detailed description of a Vpreferred.,embodiment thereof, selected for purposes of illustration and shown in the accompanying drawings, in which:

,In the preferred embodiment of our invention herein shown, we employ a conventional double seat railroad recliner chair, shown in Fig. 1, and having a base frame IU, side arms I2, cushion backs I4, and cushion seats I6. The backs I4 may be released by operation of a hand i8 connected to suitable linkage (not shown), and reclined to a position indicated in phantom at 2U. The seats I6 are covered with fabric I5 in the conventional manner and are cushioned internally by means of inner springs I8 separated from a foam rubber top layer 2l by a wire frame 25.

The leg rest includes a calf cushion 22 and a heel rest 24 and is pivotally connected to the forward 'part of each seat I6 as will be explained below. The calf cushion 422 includes a foam rubber top layer and a fabric covering similar to the seats Iliand is supported by a frame 23 which may preferably vbe of rectangular hollow metal construction. The heel rest 24 is mounted within tubular frame 28 pivotally connected to the calf cushion frame 23 by bearings 30 and is provided at the lower end of the heel rest 24 with two wheels 32, one on each side, for the purpose of allowing the heel rest 24 to move smoothly along the oor into the stowed position as will be explained more in detail below. The tubular frame 28 of the heel rest 24 extends along the sides of the said heel rest 24 parallel to it and then bends sharply downward below the end of the heel rest 24 for the purpose of elevat- .ing the said heel rest 24 a convenient distance from the floor when in the leg rest position. A hand strap 34 issecured to the lower front corner of the calf cushion 22 and is made of suitably sti material to maintain it in a forward position'where it may be conveniently reached for elevating the leg rest. In order to rotate the car chair, as illustra-ted in Fig. 2, the composite leg rest may be elevated to a position substantially above the seat I6 and locked in that position as will be further explained below.

When Vthe leg rest yisset up for use the calf cushion 22 and the heel rest '24 come into alignment with their top surfaces'in the same plane sloping' forward atiapproximately 30 below the horizontal. In this position, the frame 28 of the heel rest24 comes up against stops 36 secured to the calf cushion frame 23 which hold the leg rest rigidly against further downward movement.

The chair seatv IB is provided with a horizontal base plate 44 upon which the inner springs I9 are mounted in the central and rear areas of the seat and to which the lower margin of the fabric I5 is secured. Tubular hook members 45 and support blocks 41 having ber caps 49 are secured to the bottom of the seat base plate 44 for the purpose of supporting the seat I6 upon the chair frame I0.

The calf cushion 22 is connected by means of links 26 to pivot bearings 38 mounted at each side within the upper forward portion of the seat I6. The bearings 38 are each supported by a rigid frame made of hollow rectangular metal tubes suitably connected to each other by welding or brazing and bolted to the seat base plate 44. The

thfavailability ofcushioning space in the for-.

ward wall il. In order toprovide as much cushioningas possible abovethe bearings and at the' saine ytime allow the calf cushions 22 to be eievate'd above/the seat 'It' 4ui@ links' 2e are Y formed in anY exaggerated hook shape such that wh'enthev calf cushionl 22 is in the fully elevated position,'the links 26 extend forward from the hearings`f38, outward through the forward wall f1 and thenv upward andover the foam ruberzl., y l A 'Fuithermore, ritis important to keep thev gap, betweeny the"ca1f cushion 22 and the seat i6 at a minimum-'when'the leg rest is set up for use,'and tov this en'd the calf cushion 22 is given a'decided rearward slope from the point whereit connects to the 'links26. Thus, when in position for use the calf cushion rearwall slopestoward the seat an'di'no subs'tantial'gap existsu between the leg rest Yand the seat. Y Turning' attention now to the stowed position of the calf cushion 22,` it must be borne in mind that the hand strap 34 of the cushion 22 must not be so near the floor that it is inconvenient Ito reach. And on ythe other'hand the calf cushion 22 must be stowed without sacrificing too much cushion depth. In order to meet thesetwo competing factors, the calf rest is lodged in a recess 52 (see Fig. l) in the lower forward portion of the `seat I6'. The bottom plate 4d of the seat I6v is recessed accordingly to receive thecushion 22,. and the bearings 3S and their struts Ml flank the recess 52. However, since the calf cushion 22 enters the recess 52 at a point well below the bearings 3,8, an intermediate spring supporting frame is placed between the said bearings to augment the cushioning of the forward wall .il ofthe seat I6 between the bearings 38. The said intermediate frame includes a base plate d5;

i The, i. egv rest herein described pivots freely about 1Lthe bearings 38; and when inthe stowed position would normally rock forward and backwardY with the motion of -the train. yIn-order to. prevent this and, tov provide means;V for holding the ,leg rest the stowed position,.we provide retarders made of spring metal strips 64 mounted upon support blocks which in turnaresecured on, the inside of the outer side walls 54. The strips 64, are eachben t to form laterally extending humps indicated lat 'l0 and are held by thesupport blocks 6,8 with the said humps intercepting the path of the links 26,when lthe calf cushion 22isin the stowed position. The strips Stare .each reinforced beneath theirhumped portions ,by rubber fillers l2.k one end of each strip, 66 is .secured tothe supports 68 with the other ends free to slide when the links 26 depress the humpsll.; It-will benoted that the strips 64 are aligned roughly tangent to the path of the part of each link 26 which engages the said strips, thus vpromoting a free sliding movement ofthe linksZover the humps 10.

In addition to providing retarding means` for holding Athe leg rest in the stowed position, additionall spring. metal strips 66 are provided for the purpose ofretarding the fall of the leg rest from the elevated position. The strips 66 are locatedto intercept the links 26 in their forward arc. They are supported by lower extensions T4 'of Athe'cor ner.members 62, and extend upward alongthesurface ofthe corner members 62 adjacent .to the recess 55 Similarly to the strips 6 4, `thestrips are bent to form humps 16 having rubber fillers 18.v They are likewise disposed roughly tangent to the path of the links 26, have one end free to slide, and depress when in contact with theilinks 26.

With reference to Fig. 6, it will be evident that thelinks 26, when in the stowed position of the 'leg rest (indicated in full lines), extend immediately beyond the apex of the hump 'I6 of the strips 64 and serve to hold the leg rest in the said stowed position. When the leg rest is in a position roughly between the fully elevated position and the leg rest position, the links 26 will be located substantially as indicated at in Fig. 6, and will come in contact with the hump 16 of the strips 66. It is further to be noted that, in the leg rest position indicated in phantom at 82 in Fig. 6, the links 26 will have passed beyond the humps 'i6 of the strips 66.

In order to facilitate rotating the chair, mechanism is provided for locking the leg rest in the fully,l elevatedposition, and includes a .metal socket 84, located in each side wall of the heel rest 24, a plunger 86 having 'a rounded head 88 and a. flange S at its outer end adapted to iit into the socket. The plunger 86 extends into the socket 84 and passes through its base. A helical compression spring 92 surrounds the plunger 86 within the socket 84, the said spring 92 abuts against the bottom of the socket 84, and bearing at its other end against the flange 90, urges the plunger 86 outwardly. The plunger 86, however, is retained within the socket 84 by a retaining pin 94 fitting into a slot 9S in the inner` end of the plunger 85l thus the outward motion of the plunger 86 is stopped While at the same time the saidplunger may be moved inward against the force of the spring 92.

When the heel rest 24 is folded toward the calf cushion 22, the rounded heads 88 of the plungers 86 are depressed by the links 26 and slide into suitably counterbored holes 96 in the links 2B. Thus it will be seen (in Fig. that, when the calf cushion 22 is in the fully elevated position, the heel rest 24 may be jackknifed towards the calf cushion 22 and locked in such position. It will further be-noted that the` bottom end of the heel rest 24vwill then abut against the bottom plate 44 of the seat I6 preventing downward rotation of the composite leg rest.

The operation of the leg rest of our invention is as follws. Starting in the stowed position as indicated to the right in Fig. 1 and in the bottom phantom View of Fig. 5, the wheels 32 rest upon the floor and the calf cushion 22 is held in the stowed position by the links 26 which at that time engage the hump 'I0 of the retarder strip 64. `In order to set up the leg rest, the occupant of the seat reaches down, grasps the hand strap 34, and pulls it forward and upward. The link 26 depresses the hump 'ID of the strip 64 causing the free end of the strip 64 to shift downward slightly and allow the said link 26 to slide past it. The next steps are to elevate the cushion 22 to an intermediate roughly horizontal position, allow the heel rest 24 to swing forward, and then drop the calf cushion 22 into the assembled position where the stops 36 come into contact with the tubular frame 28 of the heel rest 24, preventing the calf cushion 22 from dropping further. It will be seen that during this operation the link 26 will come into contact with the hump 16 of the strip GS on the way up and thereby retard the movement of the cushion 22. Dropping the calf cushion 22 thereafter into the fully assembled position will be retarded lessening the chances of a sharp and possibly damaging fall. In the assembled position, however, the link 26 actually does not contact the hump 16 of the retarder strip GS; and therefore, initially lifting the cushion 22 for the purpose of re-stowing the leg rest or otherwise, is not met with immediate resistance other than the weight of the leg rest. Further lifting the calf cushion 22 to the fully elevated position enables one to engage the bullet lock and hold the leg rest in the fully elevated position as was explained above.

It will be noted that the relative lengths of the calf cushion 22 and the heel rest 24 are important. In the irst place the calf cushion 22 must A not be so long that the hand strap 34 is inconyveniently near the floor and in the second place,

the calf cushion 22 must not be so short that it must be almost fully elevated in order to allow Lhe heel rest 24 to pivot forward from-the stowed iosition. Furthermore the composite leg rest rust be sufficiently long to provide a reasonably horizontal position forv the legs. We have combined these considerations in this preferred embodiment of our invention by constructing the leg rest to accommodate approximately a 30 slop-` ing angle for the legs with the calf cushion being approximately eight inches long and the heel rest approximately a foot long. Furthermore,` with this construction, the calf cushion 22 need not be elevated beyond the horizontal position to enable the occupant to swing the heel rest forward. It is to be further noted that the leg rest of our invention does not extend fully to the side of the seat 16', but room is provided on either side of the leg rest for the occupants legs while he is assembling the leg rest.

This preferred embodiment of our invention may be adapted for use in conjunction with other types of cushion furniture including household furniture, as well as chairs, benches, and the like. Also certain structural variations will be evident to those skilled in the art. For instance, the recess 55 may be given a cylindrical contour with the upper rear Wall of the calf cushion 22 correspondingly cylindrical. Furthermore, the bearings 38 may be provided with helical springs for the purpose of facilitating the upward rotation of the leg rest. Therefore it is not intended to confine the invention to the preferred embodiment herein shown but rather to measure it in terms of the appended claims.
