10 Claims.

This application is a continuation in part 'of application Serial'No. 164,282; filed Sept. 1'7, 1937, Patent No. 2,148,898; dated Feb. 28, 1939.

This invention relates to chairof the collapsible type, used at beaches, pleasure resorts, deck or lawn or the like; and the objects are,-in addition -to those already statedinthe above said application:

1. To provide a structure which affords quick adjustments and wherein the parts are unlikely .to become disarranged.

.2. To provide-a collapsible beach chair and cot,

wherein the back rest :frame head end portion is supported free from the'ground area when the chair is converted into a cot.

3. To make :novel provision for forming the side .rails of the'back rest frame into-arm rest portions,

so that the user of the structure may be more comfortable when the back rest frame is below the main arm rests.

4. To provide a beach chair and cot wherein the supplemental leg frame and transversebrace frame facilitate shelving space which remain unobstructed by the back rest frame in 'any'adjusted position the structure may be.

5. To provide-an improved rack element'on the supplemental leg frame to serve as shelf element ata higher elevation on the back rest frame and also as rack element in any position the structure is used.

.6. To make novel provision for securing the fabric of the back rest-and the inner end of the seat frame on the structure and which affords means for tightening of the fabric "when it becomestoo stretched especially :in thecenterporextended position 'as a cot and thus affords the occupant of same a forward'visionwithless effort, will appear as the description proceeds when taken in connection with :the accompanying drawing, in which: i

Fig. 1 is aside elevational view of the structure constructed according to the invention, in extended position as a cot.

Fig. 2 is a plan view of Fig. 1.

Fig. 3 is a sectional view along the line 33 of Fig. 2, .but the-rack element, withintthe boundaries of the leg frame, isin open position.

FigA-is a sectionalview substantially along the line 4--4 of Fig. 3.

Fig. '5is the same structureas shown in Fig. :1, but in oneof many positions when it is converted intoa chair and the back rest frame is'below the arm rests. The dotted lines indicate another position'of the leg frame on the rear legs of the structure.

Fig. 6 is the. same as Fig. 1, but the same 'structure is shown in -a position it assumes when the back rest frame is connected with the arm rests. The dotted lines indicate additional positions "of the back rest frame and'leg frame and also the position of the rack element when it is open.

Fig. '7 is an enlarged'fragmentary sectional view along'the lines 1-1 of Fig. 6.

Fig. 8 is an enlarged transversely sectional view at'the junction of the fabric of the seat andback rest frame. i

Referring more specially to the-drawing, Figs.

1 to 8 give one form of the invention and wherein the numeral I indicates front legs, 2 rear legs. Arm rests are provided with upper portion 3 and lower portion 3a. 4 are link elements, 5 isa transverse braceframe, fi'is aseat frame, 'I' aback rest frame with -a legframe '8 and an additional frame'9.

As shown, the legs 1 and .2 :are positioned 'in alignment forwardly and rearwardly-of the chair structure and their upperends are pivoted to-the portions 3a of thearm rests by rivets or bolts 10 and I I. Pivotally connected with theupperend vof the rear legs and rear end .portionof the arm rests is the upper end portion of the link elements 4. I

The front legs I are connected by a pair of .bars l2 and I 3', the rear legs by a pair of bars l4 :and i5, and the link elements by a bar L6. The bars 12 and it are, disposed at equal distance from the arm rest portions 3a and, .pivotally connected therewith are the side rails of the seat frame 6. It is obvious from the drawing that, the front end of the rails of the seat are against the inner side of the front legs and rear ends are against the outside of the link elements and are pivotally connected therewith in 'a' manner so that the said side rails of the seat are at all times parallel and also in vertical alignment with the portions 3a of the arm rests, and the link elements are'substantially parallel with the front legs.

The frame 5 isintended .to be positioned in a manner different from that shown in my application Serial No. 164,282 (Patent No. 2,148,898) whenrit is in engagement with the lower portions of the rear legs 2. Therefore I make this frame so that it will be at all times separated from the back rest frame and thus affords shelving space in any adjusted position .of the structure. In this form shown, the inner end of the brace frame 5 is pivoted to the lower end of the link elements 4 at l! by screws or bolts, but it may be also connected by a cross bar if so desired, and the side rails are provided with recesses 18 on the underside and other recesses IS on the outer end of the. frame 5 for engagement with the cross bar M of the rear legs 2 to secure said legs in adjusted position. This frame 5 comprising end rails or

bars

20, 29a and, braces Zl 2| crossing each other and whose ends are disposed at the jointure of the side rails of the frame 5 and

end bars

20, 29a.

22 are slats secured at the upper surface of the 1

ends bars

20, 29a and braces 2|, 2|.

The inner end of the back rest frame 1 is pivoted on bar 16 and the upper or head end. is provided with the usual bar 23 as shown in the drawing. The side rails of this back rest frame are so formed at 24 to provide a resting place for the arms of the occupant; when the back rest frame is below the arm rests when the structure is extended in use either as a chair or as a cot. The end portion of this portion 24 is provided with means 25 which may be inclined in respect to the side rails urging-thereby the upper portion of the structure against the'side rails of the back rest frame and engageable in recesses 25 spaced on the arm rest 3 in a manner so that the back rest frame is adjustably secured with the arm rests and. the

portions 24 by their inclined ends 25 will prevent k be reached conveniently byjthe user of the structhe sides of the structure from spreading open at the upper portion thereof. frame is also provided with recesses at 2'! spaced on the rearv side and these recesses are formed to fit over cross bars l5 and adjustably secure the back rest frame to the} said cross bar l5 and thereby uniting the rear legs with the front legs. It is obvious that, when the back rest frame is being swung further rearward, its positions at said cross bar l5 will afford the'free end portion of said'leg frame to unite with the free end portion of said brace frame upon said cross bar I4. Thus, both said frames by their positions tend to form braces which, being substantially vertical and opposed to each other, are extending from the 7 functions to prevent the rear legs from spreading rearwardly and to support the back rest frame when the structure is in the position shown. Also, in other adjusted positions, such as shown in Fig. 5, the leg frame 8 stabilizes the back rest frame when it is positioned as indicated by the dotted lines in said figure. It will be noted that the lower connection at 28 which is in the form of recesses on the extreme end' portion of the leg frame 8, is not on the bar [4 of the rear legs, but on the bar 20a of the frame 5; thus the free end of frame 5 is pressed down upon the bar M by the frame 8 and to produce increased stability to the structure. This frame 8 is adapted to be swung from the rear of the back rest frame about the pivotal connection to the front of the back rest when the structure is collapsed. This frame 8, the upper ends of the side rails of which are pivoted to the bar 23 comprises a pair of

cross bars

29, 29a which connect the side rails. 30 are dowels (as shown in Fig. 4) or slats (as shown in Fig. 7) and they are disposed parallel with the side rails and their ends are secured at the

bars

29, 29 11. It is obvious, that the dowels orslats 39 as-well as the slats 22 are preferably disposed so that they run longitudinally in respect to the device so as to forms. continuation in respect to one an.-

The back rest other when the free end of the frame 8 and that of the frame 5 are engaging the cross bar l4; also that when both

frames

5 and 8 are in said position the shelving space or area is increased and articles disposed thereon are prevented from falling therefrom and further, such articles need not be removed when the chair is converted into a cot. And the dowels or slats 30 are so disposed to produce rack facility which affords convenience for articles to be hung thereon at all adjusted positions of the structure.

3| are plate. elements, secured by screws or rivets 32 on the side rails of frame 8, to contact withthe front of the side rails of the back rest frame and therewith stabilize the frame .8 in any position with the back rest frame. These plate elements are of a length sufficient to form an inner and outer projection 3m and 3lb on each side rail of the frame 8. Projection 3 lb is adapted to come in contact with the fore and rear side of theside rails of frame 1 and thereby provides means for bracing the frame 8 in either open or closed condition when said frame 8 is swung about the jointure between theback rest frame 1 and leg frame 8; while the portion or projection 3la serves to check the position of'the frame 9 when in open and also closed positions, as is evident from the drawing.

The frame 9 serves as a shelf element which can ture from over cross bar 23"and it affords a' place for articles, which are preferably separated from the lower or bottom shelf element under the seat. One form of this frame 9 shows the side rails pivoted' with the side rails of the leg frame 8 by rivets or bolts 33;. the pivotal connections being adjacent bar 29, and cross bars34 connect the side rails. 35 is a recess on each'side rail disposed'in 25 contacts the side rails of another frame 9 and it a manner so to clear bar 29 whereby both frames 10 .closed position and the catch (not shown) may be disposed on the side rail toco-ope'rate with the '45 plate element 3| or with the bar 23. In the "seat and back rest frames of this form of the invention I use a fabric element 36 which is commonly'e'mployed instructures used on beaches. And in Fig. 8, is shown a novel manner whereby the fabric. element can be tightened and held in proper condition especially when the fabric element-becomes stretched after frequent use. The bar [6 is constructed so 'as to formtwo halves 3'! of a length substantially the width of the fabric 36 inner ends of which are inserted therebetween. Said inner ends, being of the seat and back rest, are secured by bolts 38 which tighten the. halves of the bar I6 and the ends of the fabric element. The bolts are spaced on the bar I 6 in apertures having washers 39. The other end of the seat and back rest receive the fabric element, in the usual well known manner, on bars l2 and 23 respectively.

The panel of the'frame 9 may be of wood or of similar material as of the seat or back rest, but herein as shown said panel is constructed of a plurality of slats 40 which runparallel the side railsof the frame 9.

The improved chair and cot, though light in weight, is strong and durable and is extremely comfortable for the occupant, and is adjustable with practically little effort and gives positive with and convenience for articles to be disposed of 'they are used in a generic and descriptive sense only, and not for purposes of limitation, the scope of the invention being set forth in the appended claims.
