LOUNGE CHAIR Filed July 27, 1945 2 Sheets-Sheet 2 INVENTOR Patented Sept. 21, 1948 UNITED STATES PATENT OFFICE LOUNGE CHAI R v Ferdinand Kramer, Port Chester, N. Y, Application July 2'7, 1945, Serial No. 607,284

My present invention relates generally to furniture, and has particular reference to chairs and settees of the kind which are primarily intended for use on porches, terraces, and in other informal surroundings.

It is a general object of the invention to provide certain structural innovations in the type of lounge chair in which the parts may be conveniently adjusted to bring them either into a compact relationship for purposes of shipment or storage, or into selected setup relationships in which varying degrees of sitting or reclining comfort are afforded.

A chair embodying the features of the present invention is composed. of a relatively small number of constituent parts each of which is simple and inexpensive in structural character; it is staunch and stable; it is unusually comfortable; and it is highly ornamental in appearance. It may be manufactured, as may be desired, of wood, metal, plastics, or other structural materials; and it lends itself readily to the employment of a wide variety of attractive seat and back. coverings and other ornamental embellishments.

A characterizing feature of the invention resides in the employment of only three simple basic frames which may be designated, for the sake of convenience, as a bracing frame, a seat frame, and a back frame, these parts being pivotally associated in a special but simple relationship which achieves the desired objectives in an unusually eificient manner. Briefly, when the device is set up, the bracing frame slants rearwardly upwards with its lower end defining a front support, the seat frame slants forwardly upward and intersects the plane of the bracing frame, and the back frame is pivoted at its upper are the simplified details of the frames themselves, the improved means for retaining the parts in the selected set-up relationship, and the, provision of arm rests whose design and mount-' ing are of special character.

One way of achieving these general objects and advantages, and such other advantages as 6 Claims. (01. 155-117) l 2 may hereinafter appear or be pointed out, is exemplified in the accompanying drawings, in

which: I

Figure 1 is a perspective view of a lounge chair constructed in accordance with the present invention;

Figure 2 is an exploded view oflthe parts entering into theconstruction; v

Figure 3 is a longitudinal cross-sectional view of the chair in set-up condition; and

Figures 4 and 5 are views similar to Figure 3, showing su ccessive steps in the collapsing of the device into compacted storage or shipment condition. i

The device I have chosen to illustrate is a chair whosestructural elements are composed of wood, but it will be understood that any other suitable material may be used, if desired.

I have shown a bracing" frame composed of a pair of spaced elongated elements l0 and H, and a cross-bar l2 extending between them. This cross-bar is positioned relatively near the lower ends of the elements l0 and ll, these lower ends defining afront support for the chair when it is set up, andthe cross-bar l2 defining a seat support. 3

The seat frame is similarly composed of a pair of spaced elongated elements l3 and llfand is provided with a pair of across-bars l5 and I6, the

of the seat frame elements, the cross-bar I6 being rearwardly positioned. The rear or lower ends of the seat frame define a rear support for the chair when it is set up, and I have shown the possibility of securing wheels ll, of apprea ciable diameter, to these rear ends. The provision of such wheels is optional but is desirable because of the facility with which the chair may be moved from place to place when it is tipped slightly to rest on these wheels alone. A crossbarl8 mayextend between the wheels I! and may have its ends rounded to serve as bearings upon which the wheels are rotatably mounted.

The back frame is composed of the spaced

elongated elements

19 and 20, and the cross-bars 2| and 22, these cross-bars being preferably arranged adjacent to the upper and lower .edges of the back frame.

In assembling the device, the upper edge of the back frame is pivoted to the upper ends of the bracing frameelements l0 and H. This may be accomplished by simple pivot pins extending through preformed openings 23 in the elements I 0 and II, and. similar openings 24 in the elements l9 and 20, although any other convenient pivoting expedient may be employed, if desired.

The back frame elements l9 and 20 are so spaced that the width of the back frame, throughout its extent, is narrower than the space between the bracing frame elements I and II. That is, in pivoting the back frame to the bracing frame, the elements l9 and 20 lie on the inside of the elements I0 and ll, respectively.

The back" frame h'as its lower edgepivoted to the seat frame at a midportion of the latter. The preferred way of accomplishing this is to provide upstanding lugs 25 on the seat frame elements l3 and M, respectively, these lugs being positioned directly behind the cross-bar I6 and being provided with openings 26 adapted to align with openings 21 in the back frame elements l9 and 20 so as to receive pivot pins or the like. This mode 4 set up, it assumes the appearance shown in Figure 1. One set of notches (28, 29) is in engagement with the upper attenuated edge of the crossbar l2. This defines a rigid stucture of great strength and stability, since it is basically triangular in nature, as shown most clearly in Figure 3. One arm of the triangle consists of that portion of the bracing frame which extends from its upper end to the seat support l2. Another arm of the triangle consistsjof the backframe. The third arm of the triangle consists of that portion of the seat frame which lies between the lower edge of the back and the seat support I2.

I This rigidity is retained even when other sets of notches are engaged with the seat support l2. In Figure 3, for example, the foremost set of I notches is engaged with the cross-bar I2. This of pivoting permits the seat frame and the back frame to be brought into superposed relationship (see Figures 4 and 5) when the device is to be adjusted into a collapsed condition. y

As in the case of the back frame, the seat framehas a width which is, throughout its extent, narrower than the space between the bracing frame [3 and M with a series. of longitudinally-spacedv notches. vIlhave illustratively shown three such notches 26 formed on the under surface of the seat frame element I3, and a corresponding and respectively aligned set of notches29 on the under surface of the seat frame element [4.

Where it is desired-to provide arm rests, they are associated with the bracing frame as shown most clearly in Figure 2. a The arm rest 39 has a depending innerwall 3|, provided at its .rear end with a pivot opening 32 and with an arcuate slot 33. The wall 3! is applied to-the external. surface of the. bracing frame element l0, and a threaded pin..3 l ispassed through an opening 35 and through the opening 32, a wing nut 36 being then applied to hold the parts in releasable engagement. A similar pin 3'! extends through an opening 38 in the frame element), and then passes through the slot 33, a wing nut 39 engaging the end of the pin. In similar fashion, the arm rest 40 is provided with adepending wall portion 4|, and

pins

42 and 43 effect the desired engagement in the manner hereinbefore described.v

It will be observed that the seat frame and the back frame are eachof such character that any selected type of upholstery may be provided thereon. I have illustratively shown-a series of I interlaced strips 44 secured to the seat frame, and a corresponding set of interlaced strips 45 secured to the back frame. Th'ese strips may be applied in any desired manner, and are merely illustrative of the type of ornamental andcomfortable span' and does not extend downwardly beyond the latter, 1

For the sake of convenience, the frameele ments have been shown .in their originalbarestate in each of- Figures 2-5.

Whenthe parts are assembled, and the chair is establishes a predetermined angularity of the seat and back-frames with respect to the horizontal,

and with respect to each other. By lifting the seat frame'by a slight amount, and pulling it forwardly, the second or third set of notches may be caused to engage with the-seat'support 2, and this adjuststhe chair to a different angularity of the seat and back frames with respect to the horizontal, and with respect to eachother.

Inany of the selected adjustments, the chair is unusually comfortable, since there is a firm seat, for a person to sit upon and a firm back to lean against, and since both the seat and the back canbe-comfortably and resiliently upholstered. The Weight of the sitter does not alter the relationships of the parts, as is often the case in connection with ordinary so-called camp chairs or withreclining chairs having long strips of canvas or the like which sag. uncomfortably under the weight of a sitter., Noris the. sitter subjected to the uncomfortable hard feeling which is customarily experienced in acollapsible chair, such as a bridge chair or the like, where the seat and back are often unuph'olstered, non-adjustable in angularity, andwhere the seat portion is, rigidly horizontal, rather than rearwardly inclined as in thepresent case,

Similarly, weight that may be applied to the armrests of the] present chair does not have anytendency to disturb the, stability of the chair, nor does it tend to press the arm rests out. of position; As will be observed in Figure 3, down- Ward pressure uponthe arm rest forces the pin 31 against the forward end of the slot 33, thus affording a firm resistance to the Weightv which may be'applied. I

Coupled with the foregoing advantages, is the ability to adjust the present chair into a collapsed condition so that itmay be conveniently stored or shipped in a compact relationship of parts. Inaccomplishing. this objective, the wing nuts 36 and 39 (and the corresponding Wing nuts at the opposite side of the bracing frame) are slightly loosened, andthe arm rests areswung,

ures 4 ,and 5m bring the parts into-the com-.

pacted relationship shown in Figure '5.

Obviously, the chair may bemade wider, without altering its ,basic structural nature or advantages. The term lounge chair as used herein and in the appended claims, is therefore intended to include within its scope, any bench, settee, or similar device.

Also, while I have shown a seat support in the form of a simple cross-bar l2 and a means for engaging this seat support by means of notches in the seat frame, equivalent expedients may be employed to accomplish the same general objective, and there may be fewer or more of the selectable devices, exemplified by the

notches

28 and 29.

In general, it will be understood that the details herein described and illustrated may be modified, in a number of respects, by those skilled in the art without departing from the spirit and scope of the invention as expressed in the appended claims.

Having thus described my invention and illustrated its use, what I claim as new and desire to secure by Letters Patent is:
