UNITED "STATES PATENT OFFICE 7 a V r 2,040,942 r if SUN BATH SEAT Charles J. Katenkamp, Arlington, N. J. Application February 11, 1935, Serial No. 6,072

' 4 Claims.

The purpose of this invention is to'provide a collapsible chair or seat which is particularly adapted for beaches andresorts which may be folded to substantially a flat position so that'it may readily be packed and carried, and so that .several may be placed in a pleasure car. 7, l

The invention is a seat formed with a flat board having a pivotally supported back .slidably mounted on the board, and also a hinged member below the, forward end adapted to raise the forward end thereof. The seat is so constructed that with the weight of a person thereon a'considerable pressure may be placed against the back without raising the seat. 7

Many devices have been provided for exposing the body to the sun on beaches andin-resorts and the like, and also providing rests or reclining devices; however, substantially all of these are either in the form of folding chairswhich require considerable space when folded, or mats or spreads that may be placed uponthe sand or the like, and these are not provided with back rests or means for elevating the forward end of the seat. It is, therefore, desirable to provide a device adapted to give the same comfort as a folding chair which is substantially formed of a plain board and which, when folded, will occupy about the same space.

The object of the invention is, therefore, to provide a collapsible seat having an adjustable back in combination in which the entire'device may be folded to occupy the space normally required for the seat alone.

Another object is to provide a collapsible seat in which the position of the backin relation to the length of the seat may readily be adjusted. A further object is to provide means foradjusting and supporting a back from a seatin which the point to which the back is joined to the seat may-be moved in relation to the length of the seat.

A still further object is toprovide a collapsible seat which provides substantially the same comfort as a folding chair which is relatively small and of a comparatively-light weight.

And a still further-objectds to provide a collapsible seat which may be'folded to occupy sub stantially the same space as the seat alone which is of a simple and economical construction. v

With these ends in view the invention embodies a seat comprising a flat board, legs adapted to elevate the forward end thereof, a back, means adjusting the angle of the back in relation to the seat, and also means adjusting the position of the back in relation to the length of the seat.

Other features and advantages of the invention will appear from the following description, taken in connection with the drawing, wherein:

Figure 1 is a view showing a side elevation of the seat with the back extending upward and Figure 5 is a view showing the socket on an 5' enlarged scale.

Figure 6 is a detail showing the latch for holding the back in different positions ontlre seat. 2

In the drawing therseat is shown'as it may be made wherein numeral I indicates the seat, nu-

meral 2 the back, and numeral 3 the slidingcanriage in which the. back is held.

The seat is made of a fiat piece of material, and may be wood, metal, or any materiaL however in the design shown it is made of wood, and the sides are provided with metal inserts 4 with their rear ends connected by a metal cross member 5. The inserts 4 are provided with holes 6 in which pins 1 from the latches 8 extend, as shown in Figure 6, and it will be noted that the latches are held in the closed position by springs 9 and are hinged to the side plates ID of the carriage 3. The latches 8 may be provided with knobs II by which they may readily be opened or drawn outward to remove the pins 1 fromthe openings,

and it will be noted that with these latches open the carriage 3 is free to slide'back and. forth on the seat I so that it may be adjusted to any position, and when itis in the correct position the latches 8 may be closed so that'the pins. 1 will register in openings 6, and. thereby hold the carriage in position. In the-upper ends of the side plates [0 are circular sockets I2 into which hubs [3 at the lower ends of the back 2 extend, as

shown in Figures 4 and 5. It is preferred to make the hubs l3 of metal and these are eachforme'd with a metallic channel shapedsection I 4-exwhich pins l8 which are slidably held in bosses 19 on the upper'surfaces' of the sockets I2 may extend, and it will be noted that with these pins in the downward position they will extend into the openings l1 and hold theback in relation to theseat. The pins l 8 may be provided with knobs 20 and these may have springs 2 I below the knobs which will'tend to raise the pins so that when it is desiredito release the back, it is only necessary to exert a slight; forward pressure thereon so that the binding on thepins caused thereby .is removed and thepins are released and the spring will then raise the pins out of the openings ll so thatthe back may be moved over or adjustedtoany posi,-. tion.' The position of the pins l8 may also be held by spring pins as hereinafter described, if

.desired. -When the back is in the desired position,

the pins may be pressed downward into" the openings I1, and the weightmfvtheback due toitstilt will cause the hubs l3 to exert pressure on the pins and thereby hold the pins in the openings :by friction. It..will .be understood that any other .means..may-.bez.used for adjustably holding the :back in relation to the seat, and the. holding meansmay beslidablein-relation to the seat, or held thereon inany manner. e V, V V

The bosses l9 are provided withset screws :22

' which.extend.into-slots 23 in the pins l8 to limit their'upward movement,,.as it will .be noted that when the-pinsare released thesprings will move them upward untilthe lower ends of theslots 23 engage the set screws. This permits thepins to ,move out, of the openings H but holdsthem in position. 7 1 V .In .thedesignshown, the back 2 isformed with ftheside bars 15, a cross bar 24 at the top and, the

intermediate ,portionis covered by..canvas .25,

however it will beunderstood that the intermediate ,portion may be covered by 7 any material, or ,arr'angedin. any manner. 7

' ..At.'the'. f0rward.end of the seat'is aleg memg' ber 261which is hinged to the under side thereof byhingesil, and this may be folded against the undersideof the seat, .or may. be opened tothe ,posjitions'hown in Figures 1 and 2 to elevate the forward-end of-theseat when desired. fflhe carriage 3 mayLbeslidably mounted upon the seat inany. manner, and any means may be used. for locating and holding the carriage .in

7' difierent ..positions.' In the design shown, .the

.carriage' isformed with'a cross plate 28 which extendsunder the seat anfd a'plate 29 which extends jover. the'upper'surface of the seat. These plates form supporting menibersfor the side plates) ofthesockets 12, .however it will be understood thatthese sockets .may be ;mounted upon the boa'rdin any manner,.or held by any means.

"It will also be notedQthat the ,pins l8 may be 9 provided with notches'30 and .3I into which spring .pinst32'which are .held inpmjections 3.3 onthe sidesofthe bosses l.9.may1snap. asthepins arrive-attheupperand lower positions. The pins 7 32 maybe held by. springs 34, and these ,may be mounted in the projections 33 in any manner.

It will ,be understood, however, that any other meansimay be used for'holding the pins attheir upper or lower positions. V I v igItiwillbe'understood that other changes ;may

be made in the construction without departing from the spirit of the invention. 'One of which changes may be in the omission of the inserts 4,

as slots and openings may be provided in the edges of the board for holding the latch of the carriage, another may be in the use of other means for connecting the lower ends of the back to the adjustable socket, and still another may;

be in the use. of other means for elevating'the forward end or any part of the seat. I

' The construction will be readily understood from the foregoing description. In use the seat ,may be provided as shown and described, and it will be noted that ordinarily the back 2 may be foldedrdownward upon the seat I so that it is parallel thereto, and the leg/26 may alsobe folded against the under side of the seat. In this positionthe. entire-seat will be comparatively'flat and occupy very little space, and as it is made of relatively light weight material, several of these may readily-be carried and a comparatively large number mayibe carried 'in an automobile.

When it. lsdesired to ,use the seats they'will be opened to theposition shown inFigure I, or the. 7 back. may. .be adjusted .to a substantially vertical position, as indicated by thedotted lines 35, or

.it may also be moved :backward .to the dotted lines 36 to'forma reclining. seat, and it will be' noted that the, weight of the body of a. person on the forward part of the seat will .make it possibleto put considerable pressure upon the .back, even inthe position indicated by the dotted lines 36. .The seatmay, therefore, be used in substantiallyany position andimay be made to accommodate large or small people by moving the lowerend of the backforward and backward upon the seat.

Having thus fully described the invention, what I claim .as new and desire to secure by Letters Patent, is: e I e 1. A beach seat comprising a relatively long hor-' ,izontal board seat section adapted to'rest on the ground, a back, a sliding member extending across andembracing said seat section and longitudinally slidable thereon, means securing said'sliding 'member indifferent positions upon the seat section, cylindrical sockets on the ends of said slidingmember, hubs at the lower end of said back positioned to operate in said sockets to adjust the position of saidback in relation to the seat sec tion, and means holding'said hubs in different 7 positions in said sockets for angular adjustment of said back in relation to the seat section.

1 2.'A beach seat as described in claim 1 characterized in that a flat member is hingedly at tached to theunder; side of the forward end of 3. A beach seat as described claim'l characterized in that the'base of said sliding memher is" relatively long providing an extended bearing surface against the bottomof the seat for V 1 f supporting said back- 4. A beach seat as. described acterized in that a portion of the seat extends rearwardly of the sliding member;


in claim 1 char said s'eat and adapted to be vertically positioned to-raiseisaid'forward end. 7
