BY a x, xxx g March 13, 1962 D. w. MOHROR 3,025,103 TABLE ATTACHMENT FOR LAWN CHAIRS Filed Aug. 17, 1960 2 Sheets-Sheet 2 nite tats This invention relates to an attachment particularly, although not necessarily, for lawn chairs of the vertically oscillating or rocking type comprising tubular arms integral with the upstanding legs of a generally U-shaped, stationary, resilient metallic base, and has for its primary object to provide, in a manner as hereinafter set forth, readily removable side table which is adapted to be expeditiously mounted for use on one of the arms of such chairs without altering the same structurally and, further, without extraneous securing means.

Another very important object of the present invention is to provide a table attachment for chairs of the aforementioned character which will maintain a level or hori- Z-ontal position at all times.

Still another important object of the invention is to provide a table attachment of the character set forth which may be readily adjusted for use on various chairs.

Other objects of the invention are to provide a table attachment for chairs which will be comparatively simple in construction, strong, durable, compact, of light weight and which may be manufactured at low cost.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

FIGURE 1 is a perspective view, showing an attachment embodying the present invention mounted on a chair;

FIGURE 2 is a view in side elevation thereof;

FIGURE 3 is a front elevational view;

FIGURE 4 is a bottom perspective view of the device per se with portions omitted;

FIGURE 5 is a detail view in perspective of one of the resilient clips, of which there are four;

FIGURE 6 is a detail view in perspective of the slidable sleeve which, in conjunction with a clip such as that shown in FIGURE 5, slidably connects the rear end portion of the chair arm to the upper end portion of the panel supporting leg;

FIGURE 7 is a detail view in perspective of the socket which receives the upper end of the panel supporting leg;

FIGURE 8 is a view in transverse section on an enlarged scale, taken substantially on the line 8-8 of FIGURE 2;

FIGURE 9 is a fragmentary view in transverse section on an enlarged scale, taken substantially on the line 9-9 of FIGURE 2; and

FIGURE 10 is a perspective view of the telescopic panel supporting leg.

Referring now to the drawings in detail, it will be seen that reference numeral 11 designates generally a conventional lawn chair of the resilient, vertically oscillating type. The chair 11 includes the usual generally U-shaped horizontal base 13 of suitable resilient metal from the end portions of which legs 14 extend upwardly. The legs 14 terminate in rearwardly extending arms 15. The

members

13, 14 and 15 of the chair 11 comprise a single length of tubing. Mounted in the frame structure defined by the

members

13, 14 and 15 is a seat 16 and a back 17.

The embodiment of the present invention which has been illustrated comprises an elongated plate or panel 18 of suitable dimensions and material which is mounted longitudinally on one of the chair arms 15. The panel 13 is substantially rectangular with the exception that the atent ice outer, rear end portion of said panel is cut away or recessed as indicated at 19. Secured beneath the inner longitudinal marginal portion of the panel 18, adjacent the forward end thereof, is a resilient clip or clamp 20 which is engageable with the forward end portion of the chair arm for detachably securing said panel thereof. The clip 21) is generally C-shaped, as shown to advantage in FIGURE 5 of the drawings, and said clip includes inturned end portions providing opposed jaws 21 which receive the chair arm therebetween and frictionally grip the same. The bight portion of the clip 20 is provided with an aperture or hole 22 which accommodates a screw for securing said clip beneath the panel 18.

Mounted beneath the outer longitudinal marginal portion of the panel 18, also adjacent the forward end thereof, is 21 depending bracket 23. A brace 24 has one end pivotally secured to the bracket 23, as indicated at 25. At its other end, the brace 24 terminates in an angularly bent eye 26 having pivotally secured thereon a clip 27 which is similar to the clip 21 The clip 27 is engageable with the chair leg 14 at a point above but adjacent to the seat 16 for detachably connecting the brace .24 to said leg.

Secured beneath the rear end portion of the panel 18, adjacent the inner longitudinal edge thereof, is a socket 28. As shown to advantage in FIGURE 9 of the drawings, the socket 23 is for the reception of the upper end portion of a longitudinally extensible and contractible supporting leg 29 for the rear end of the panel 18. The leg 29 comprises telescopic upper and lower male and

female sections

30 and 31, respectively, which are secured in adjusted position through the medium of a setscrew 32. At its lower end, the female section 31 of the telescopic leg 29 terminates in a right angularly bent eye 33 having secured therebeneath a resilient clip 34, which is also similar to the clip 20, for detachably securing the lower end of the leg 29 on the adjacent leg of the generally U-shaped chair base 13. This is shown to advantage in FIGURE 8 of the drawings. The upper end portion of the male section 30 of the leg 29 is engaged in the socket 28.

A coupling 35 connects the upper end portion of the leg 29 to the rear end portion of the chair arm 15 on which the panel 18 is mounted. The coupling 35 comprises a sleeve 36 which is slidable on the upper end portion of the male section 30 of the leg 29. Mounted on the sleeve 36 is an arm 37 (see FIGURE 6), said arm having secured thereto a clip 38 which is engaged with the chair arm 15. Thus, the leg 29 is connected to the chair arm in a manner to permit vertical swinging movement of said arm.

It is thought that the operation of use of the device will be readily apparent from a consideration of the foregoing. Briefly, the device is expeditiously mounted on the chair by simply snapping the resilient clamps or clips 21), 27, 34 and 38 on the respective members of said chair. The front end of the panel 18 rests on the chair arm and the outer portion thereof is supported by the brace 24. However, the rear end of the panel 18 is free of the chair arm and supported by the leg 29. Accordingly, it will be seen that the leg 29 maintains the panel 18 in a substantially horizontal position independently of the chair arm 15, permitting said arm to move vertically as when the chair is first sat in or oscillated by the occupant. As will be readily apparent, the telescopic leg 29 facilitates leveling the panel 18 for use on different chairs and to meet various conditions. With the leg 29 mounted on the base 13 the chair 11 may be readily moved from place to place with the table attachment mounted thereon.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalent may be resorted to, falling within the scope of the invention as claimed:
