"4 Claims. (Cl. 155-56) This invention relates to a folding chair of a type commonly used upon lawns and porches, and it is an object of the invention to provide a chair of this kind embodying an arrangement of parts whereby the chair may be readily adjusted to either a sitting up position or a lying down position.

The invention also has for an object to provide a chair including a foot rest which, when in exzo tended or working position, is disposed on a downward incline so that the foot rest is out i of the way when the chair is in its normal sitting position and also permitting the foot rest to be employed with equal facility by a person with long legs or a person with short legs.

Another object of the invention is to provide a chair of this character including a foot rest pivotally connected with the chair structure proper so that said foot rest may be extended forwardly into working position or adjusted to a position behind the'occupant of the chair when it is not desired to use the foot rest, said foot rest when in its inoperative position being free of contact with the occupant of the chair or more specifically the flexible seat and back element comprised in the structure of the chair proper. An additional object of the invention is to provide a chair of this kind including a foot rest so engaged with the chair proper as to be readily l adjusted into a working or ineffective position as may be required and wherein said foot rest in its structure includes a secondary rest which, 1

also when it is not desired to use the secondary foot rest.

A still further object of the invention is to provide a chair of this kind which is constructed and assembled in a manner permitting the same to be conveniently folded or compacted when not in use and wherein the chair when extended for use substantially eliminates any tendency of the chair to mar the lawn or other surface upon which it may be resting and particularly as a result of creeping.

The invention consists in the details of construction and in the combination and arrangement of the several parts of our improved folding chair whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel featuresof our invention will hereinafter be definitely claimed.

In order that our invention may be the better understood, we will now proceed to describe the same with reference to the accompanying drawings, wherein:

Figure 1 is a view in side elevation of a chair constructed in accordance With an embodiment of our invention, a second position of certain of theparts being indicated by broken lines and which second position is assumed when the chair is used to rock;

Figure 2 is a view partly in section and partly in front elevation of the chair as illustrated in Figure 1, the section being on the line 2-4 of Figure 1; n

Figure 3 is a fragmentary View in perspective particularly illustrating the link connection between one of the side legs of the chair and a base member or sill;

Figure l is a view partly in elevation and partly in section of the chair as illustrated in Figure l, the section being taken on the line 4-4 of Figure 5, the inefiective or folded position of the foot rest being indicated by broken lines;

Figure 5 is a view in top plan of the chair as illustrated in Figure 1;

Figure 6 is a View in sideelevation chair folded or compacted;

Figure 7 is a view in elevation of the folded chair as illustrated in Figure 6;

Figure 8 is .a fragmentary detailed view illustrating a stop carried by one of the side bars of the main portion of the foot rest for contact with a leg of the chair proper for holding the foot rest when extended free for movement with the chair proper;

Figure 9 is a fragmentary view partly in elevation and partly in section illustrating an op erative connection with a side bar of the foot rest and a supporting leg of the chair properin 4 accordance with another embodiment of my invention; l l

Figure 10 is a view similar to Figure 9 but showing the bar of the foot rest in a second or raised position with respect to Figure 9.

As illustrated in the accompanying drawings, our chair comprises a pair of suitably spaced and substantially parallel elongated base members or sills I having their rear end portions connected by a cross member 2. This cross member, as 56 of the arm rest herein illustrated, comprises a flat bar which is secured from below to the sills I and is adapted to have direct contact with the surface upon which the chair is positioned.

The forward end portions of the base inembus or sills I have pivotally connected thereto, as at 3, the lower end portions of the elongated side supporting legs 4. These legs 4, as illustrated in the accompanying drawings, are each straight from end to end and the lower or pivoted portions of these legs are connected by thecrossed braces 5 each of which has its upper portion ex tending laterally, as at 6, beyond the supporting leg 4 to which it is secured. Each of these ex-,

tended portions 6 is notched or recessed at its outer or free extremity to provide a shoulder l for a purpose to be hereinafter more particularly referred to.

Each of the supporting legs 4 at a predetormined point intermediate its ends provided therethrough with a longitudinally disposed slot 8 which provides a runway for a laterally dis-- posed part 9 carried by the inner portion of an IQ. This part 9 constitutes a pivot for the arm rest Ill to permit the same to readily swing as desired while the slot 8 permits sufficient endwise movement of the pivoted end portion ofthe arm rest It along the associated side leg 4 to facilitate the desired folding or compacting of the chair and also the extension of the chair into working position.

Each of these arm rests I!) at a predetermined distanceinwardly of its outer extremity has pivotally connected thereto, as at II, a second side leg I2 also illustrated as being straight from end to end and of a length materially less than the length of the adjacent side leg 4 and which leg l2, when the chair is extended for use, is inclined upwardly and forwardly and terminates in .advance of said adjacent side leg 4 which is disposed onan upward and rearward incline. These legs 4 and I 2 are free of direct connection one with the other so that said legs are readily movable independently one of the other to facilitate folding or extending of the chair. I

Disposed laterally through the opposite or lower end portion of each of the legs 52 is a shank I4 which extends a distancelaterally from the leg i2 beyond the inner face thereof, and pivotally mounted upon said extended portion of the shank I4 is a pair of links I5 maintained in desired spaced relation by a sleeve I6 surrounding the shank I4 between the links. These links !5 engage over the opposite side faces of the adjacent sill and are pivotally connected thereto, as at I8. The portion of theshank I4 between the links I5 together with the sleeve I6 thereon is selectively received within either of the notches l9 provided in the top face of the sill I. These notches i9 are equidistantly spaced from the pivotal mounting I8 for the link and a distance therefrom to assure the proper reception of the sleeve I6 and the adjacent portion of the shank 44 in either'of such notches.

When each of the legs I2 is operatively engaged within a forward notch I9 the chair as a unit will be in sitting up adjustment whereas when eachof the legs I2 is operatively engaged with the rear notch I9 the chair will be in lying down adjustment.

These links I5 are of material advantage and importance as by the use of such links the sleeves I6 with the adjacent portions of the shanks I4 will not slip out of the notches and thus allow the chair to accidentally collapse or fall. In addition to this the links I5 provide means to further facilitate the folding or compacting of the chair or its extension, it being understood that when the chair is compacted the sleeves l6 are free of the notches I9. The side legs I2 are connected by a cross member or bar 20.

The forward portions of the arm rests H) are connected by a flat and cross member 2! secured from below to the arm rests and positioned in advance of the pivotal connections lI between the legs I2 and the arm rests Ill. Secured to this member 2! is an end portion of a flexible seat and back element 22, the opposite or upper end portion of which element is suitably secured to 'a cross bar or member 23 connecting the outer or top portions of the supporting legs 4.

It is to be particularly noted that when the chair is extended for use it will readily rock or oscillate but the forward or downward movement of the legs I2 is limited by contact with the lateral extending portions 6 of the cross members 5 within the notches thereof. is of advantage because with the legs l2 so engaged within the notches of the portions 6 each of said legs I2 is effectively held against inward lateral movement by the adjacent shoulder I; It is, therefore, assured that at all times the legs I2 will be in proper position and which is of advantage to assure not only the desired balance of the chair when in use but to facilitate the folding or compacting of the chair structure in its entirety. I

' Associated with the chair, as herein disclosed, is a foot rest comprising two sections M and S.

The section M constitutes the main body of the foot rest and, as illustrated in the drawings, thissection or body M comprises two spaced side bars 24 substantially in parallelism, and the inner or rear end portion of each of these bars 24 is provided with a slot 25 disposed' lengthwise and obliquely of the bar. The inner or rear end portion of each of these bars 24 extends across the inner face of an adjacent supporting leg 4 at the lower portion thereof and the slot 25 has disposed therethrough an inwardly directed shank 26 carried by the leg 4. 7 By this means the bar 24 is supported for convenient swinging movement. This pivoted end portion of each of the side bars 24 is continued by a rearwardly directed extension or tail piece 2'! which constitutes a stop for. contact with one of the members 5 for limiting the upward or folding swinging movement. of the bar 24 when substantially parallel with a leg 4. When the bar 24 is'in this position the then upper end wall of the slot 25 will be in contact with the shank 26. However, with the foot rest in folded position but the chair extended for use it is important that the folded foot rest assume a position sufficiently to the rear of the flexible back and seat element 22 to offer no interference therewith. Upon raising the folded foot rest so that each of the shanks 26 is in the then lower portion of the slot 25 of each of the bars 24, the tail piece will be above the cross bars or members 5 a distance sufficient to allow the folded foot rest to be swung rearwardly of the legs 4 until the inwardly extending lug or bracket 28 carried by each of the side bars 24 contacts with the front edge of an adjacent supporting leg 4. This lug or bracket 28 is positioned in relatively close proximity to the inner or pivoted end portion of a bar 24 and when the foot rest is swung into an extended or working position, each of these lugs or brackets 28 will contact with the front edge of an adjacent supporting leg 4 at a point below This particular contact The outer end portions of the side bars 24 are connected by a plurality of spaced crossbars 2!] herein disclosed as two in number.

The) supplement or secondary foot rest S comprises two sidebars 30 having their outer ends connected by the spaced cross rods 3| while the inner portions of the side bars 3i! arepivotally mounted upon the inner bar 29 connecting the sidebars 24 of the foot rest of the section or body M. The pivoted end portions of these bars 29 have tail extensions 32 which, when the sec ondary or supplemental section or body S is folded, inwardly of the member or body M, contact from below with the outer bar 29 and thereby maintain the section or body S between and substantially coplanar with the side bars 24 of the section or body M. When the supplemental section or body Sis swung outwardly or extended as particularly illustrated in Figure 4, the side bars 30 rest from above upon the outer bar 29 and thus maintain such section or body S in an angular relation with respect to the main section or body M. This is of advantage as it assures the occupant of the chair comfortably engaging his feet with one of the bars 3! and the outward and downward inclination of the foot rest as a whole together with the relative positioning of the secondary or supplemental section or body S, when the foot rest is extended for use, permits the foot rest to be employed with equal convenience and facility by those having either short or long legs.

By referring to Figure 4 it will be noted that by having the foot rest when extended for use disposed outwardly and downwardly it is out of the way thus facilitating a person sitting in the chair or leaving the same. It is also believed to be self-evident that the construction and assembly of the parts are such that the chair when extended for use is substantially free of creeping and particularly when rocking and that its assembly is such to also facilitate the desired foldhaving the front or forward edge of said mem either its upper or lower adjustment and also for limiting the extent of forward downward movement of the foot rest as well as limiting the upward or folding movement of the foot rest. In this embodiment of our invention each of the Itis also of advantage to have the cross side bars 34 of;the main sectionor body of the foot rest is provided in its rear portion with a longitudinally directed slot 35 through which is directed the inwardly disposed shank 36 carried by the adjacent supporting leg 3? comprised in the chair structure proper. When the foot rest is swung forwardly in position for use, the side bar 34 of the foot rest will contact from above with a cross member 38 connecting both of the supporting legs 31. The under edge face of each of the bars 34 of the foot rest is provided with a cam face 38, said cam face extending outwardly and downwardly so that upon moving the bar'34 inwardly with respect to the supporting leg 31, as permitted by the slot 35, the high portion of the cam face 39 will have contact with the cross member 38 and thus maintain the foot rest in a second or raised position as is particularly illustrated in Figure 10.

Whenthe side bar 34 is at the limit of its inward movement as in Figure 10, as the foot rest is swung upwardly into its folded position, the bar 34 proper will have contact from the rear with the cross member 38 whereby the side bar 34 will be maintained substantially in parallelism and coplanar with the adjacent supporting leg 37. However, if it is desired to have the foot rest swing further to the rear in order to avoid interference with the flexible back and seat element it is only necessary to raise the bar,

. as permitted by the slot 35, so that the reduced to be obvious that a folding chair constructed in accordance with our invention is particularly well adapted for use by reason of the convenience and. facility with which it may be assembled and operated, and it will also be obvious that our invention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason we do not wish to be understood as limiting ourselves to the precise arrangement and formation of the several parts herein shown in carrying out our invention in practice except as hereinafter claimed.
