OFFICE COLLAPSIBLE FEEDING TRAY ATTACH- MENT FOR CHAIRS John J. Scanlon, Bronx, N. Y.

Application January 8, 1949, Serial No. 69,857

4 Claims.

This invention relates to new and useful improvements in furniture articles for babies, and, more particularly, the aim is to provide a novel and valuable collapsible appliance for erection and attachment to an adults chair and then for providing a seat and enclosure for the infant or very young child such that the latter is dependably protectively positioned and facing a frontally surrounding miniature table on which may be arranged one or more suitable toys and by the aid of which the baby may be conveniently fed.

The new furniture article has very few parts, is relatively inexpensive to manufacture, and has the further advantages that it may be readily collapsed into a compact and comparatively small unit, as for carrying the same in collapsed condition even in a moderate size suitcase or the like. As thus collapsible, and in its now preferred form, the new appliance comprises merely a substantially U-shaped'table, and three legs hingedly connected at their tops to the underside of said table, whereby for erecting the appliance said legs may be swung to dispositions perpendicular to the plane of the table and for collapsing the appliance the legs may be swung to extension against and parallel with the bottom of the table and in the latter case with both opposite ends of all the legs within the area of the table.

A further feature of the invention is the provision of an efficient and entirely reliable latching means for insuring against accidental collapse of any leg when the appliance is erected; this latching means, in its now preferred form, including elements analogous to those characteristic of a snap fastener, combined with a readily accessible finger-piece manipulable for quick release of such snap fastener means in preparation for collapsing the appliance.

Also, according to the invention, mere frictional engagement or any special engagement of the bottoms of the legs with the seat expanse of the adults chair, when the new appliance is erected,

is not depended on in any way to maintain the erected appliance at its prevised placement on the adults chair, but, instead, there are provided positively functioning means for absolutely securely temporarily coupling together the adults chair and the new appliance inerected condition; said positively functioning means being so constituted that the same is substantially instantaneously attachable to and detachable from parts of the back of the adults chair. At the same time, the parts of the new appliance are so arranged that the appliance in erected condition may be left thus coupled to the adults chair, even during the time when the latter is pushed in under a dining table as is desired between meals in a well-ordered home.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

Fig. l is a frontal perspective view, showing a now favored embodiment of the new appliance in erected condition on the seat of an adults chair and coupled thereto as above, and also showing a baby protectively positioned on the seat of the adults chair.

Fig. 2, drawn to a somewhat larger scale than Fig. 1, shows said appliance in side elevation, and, in dot and dash lines, said adults chair and also a dining table, with said chair pushed in under said table.

Fig. 3 is an enlarged plan view, with the positions assumed by the upper ends of the legs when the latter are erected indicated in broken lines, and with the positions assumed by said legs when the appliance is collapsed indicated in dot and dash lines.

Fig. 4 is a side elevational view of the new appliance, with its legs shown in full lines in their erected positions and with said legs shown in dot and dash lines in their collapsed positions.

Fig. 5 is a much enlarged fragmentarily elevational detail view, showing certain of the parts as observed in Fig. 2.

Fig. 6 is a horizontal section, taken on the line 66 of Fig. 5.

Fig. 7 is a vertical section, taken on the line 11 of Fig. 6.

Fig. 8 is also a vertical section, this taken on the line 88 of Fig. 7.

Fig. 9 is an enlarged partial vertical sectional view taken on the line 99 of Fig. 3.

Fig. 10 is a perspective view of one of the metallic channel members, per se.

Referring to the drawing more in detail, the new appliance as there illustrated is as a whole designated l5. 'The same comprises a substantially U-shaped uniplanar table or tray i6. Suitably swingably connected to the underside of the tray l6, as by the hinges l8, and at the locations best indicated by the broken-line squares of Fig. 3 representing the tops of the legs when erected, there are three legs E9. The legs l9 are all preferably of the same length, and small squares 2! 3 of felt or other soft material are preferably secured to the bottom ends of the legs to rest on the seat of the adults chair, as will become clear as this specification proceeds. The tray I6 is made of wood, but may be made of a plastic material or any other similar material.

In Figs. 1 and 2, the new appliance, erected, is shown as secured by the positive holdin means already mentioned to the adults chair 2 I, which is illustrated as a standard type of chair forming part of a dining room suite, and in Fig. 2 said chair is shown as pushed in under a table 22 also forming part of said suite.

The positive holding means is illustrated as comprising a pair of straps 23 of cloth webbing material, leather or any other suitable material. Each of the straps 23 is provided at one end with a buckle 2 3 of the friction grip type with which the free end of each oi the straps may be engaged after the straps 23 have been engaged about the vertical side risers 26 of the adult chair 2|. Each of the straps 23 has its intermediate portion slidably extended through a metallic channel 25 secured to the back ends of the legs defining a part of the U-shaped tray is. The four corners of each of the metallic channels 25 are formed with prongs 25 see Fig. 10, which are to be driven into the back ends of the legs of the tray I, as shown in Fig. 3, for connecting the channels 25 to the tray. The exposed face of the channels 25 has secured thereto by layers of mucilage 25, pieces of felt 25 which are arranged to contact the adjacent faces of the vertical risers 2t and prevent the channels 25 from marring these faces of the risers 26.

The friction type buckles 2% permit the free ends of the straps 23 to be engaged therewith regardless of the thickness of the vertical risers and slidably extending the intermediate portions of the straps 23 through the channels 25 permits the position of the straps 23 with relation to the channels to be shifted to align the buckles 24 with a fiat portion of the risers regardless of the thickness of the risers 2B.

To prevent inadvertent collapse of any leg i9, each such leg is also served by a special latch means marked as a whole 21. The details of a now favored construction of a latch means 21 are best shown in Figs. -8. This latch means is in function analogous to the ordinary snap fastener, and includes a post element carrying at its outer end a ball-shaped head 28 and having a screw shank 2c; in which latter connection it may be explained that the legs is are desirably made of wood, a plastic, metal or the like, so that in the case of a leg [9 which is of wood, said shank may have a thread'typical of that of a wood screw, or, in the case of a leg IQ of a plastic or metal, said shank may have a thread typical of that of a machine screw.

The receptor for the ball-shaped head 28 is shown as provided at the upper edge of a resilient leaf 30 upcurled from the blank of which is formed a box-like metal stamping 31 having at its top and at its two sides oppositely horizontally offset apertured ears 32 for securement, as by the screws indicated, of said stamping suitably adjacent to a leg [9 and against the under side of the tray l6. Thus, when a leg 19 is erected, it is automatically snap-latched in its erected position, by coaction between the

elements

28 and 30. A finger-piece 33 forms part of a fairly stiff metal strip 34 projected through a vertically elongated slot 35 in said stamping, and said strip is near its lower end suitably secured to the leaf 3%]; whereby, on pressing down on the finger-piece 33, the snap-latch between said

elements

28 and 30 is released. Then the legs I9 may be collapsed against the under side of the tray I6, to lie as indicated in dot and dash lines in Figs. 3 and 4.

While I have illustrated and described the preferred embodiment of my invention, it is to be understood that I do not limit myself to the precise construction herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.
