4 Claims.

This invention relates to high chairs or infants More particularly, the invention deals with a means for swingably and slidably supporting the tray or table portion of a chair in connection with the arms to move the tray or table portion out of the path of access to the seat in placing a child in or removing the child from the chair. Still more particularly, the invention deals with means for adjustably clamping the tray or table member in one of a number of .positions on the arms, adapting the tray or table to closely fit a child and aiding and retaining a child against accidental displacement from the chair, while also keeping food supported on the tray in close proximity to a child.

The novel features of the invention will be best understood from the following description when taken together with the accompanying drawing, in which certain embodiments of the invention are disclosed and, in which, the separate parts are designated by suitable reference characters in each of the views and in which:

Fig. 1 is a perspective view of a high chair made according to the invention with part of the construction broken away and showing the tray or table in operative position in full lines and in inonerative position in dot and. dash lines.

portion of the chair, seen in Fig.- 1, with parts of the construction broken away and in section.

Fig. 3 is a front view of a chair showing part of the construction in section and showing a modification.

Fig. 4 is a bottom plan view of part of the structure, as seen in Fig. 3.

Fig. 5 is a side view of a bracket portion, shown in Figs. 3 and 4.

Fig. 6 is a section on the line li 6 of Fig. 5; and

Fig. 7 is a section on the line 1-4 of Fig. 4.

In high chair constructions, it has been the general practice to support a tray or table by rearwardly extending arms pivoted at the rear portion of the chair or the back-rest thereof to swing vertically over the head of a child in the operation of placing a child in or removing a child from the chair.

It is the purpose of my invention to so mount a tray or table member as to facilitate downward swinging of the same, as well as to provide means for adjustably clamping the tray or table in one 2 is a sectional detailed view of one side u 'vides free adjustment of of a number of positions in the chair to bring the tray or table into a desirable position with respect to a child positioned in the chair and to establish a reasonably close proximity to the child to prevent accidental displacement of the child from the chair.

In Figs. 1 and 2 of the drawing, I have shown one adaptation of my invention and, in Fig. 1 40 represents a high chair which may be of any design and construction and will employ the conventional seat ll, back-rest l2, supporting legs 13, foot-rest or treadle Hi, arms l5 extending for- Wardly from the back-rest i2 and suitably supported at their forward ends by members I6.

In the present construction, the outer surfaces ,of the arms, particularly at their forward end portions, are provided with longitudinal slots, channels or grooves H, in which operates the lower flange 18 of channel plates is secured to the lower surface of a tray "or table as adjacent the side portions thereof. This construction prothe tray or table into d-iiferent positions longitudinally of the arms l5 while, at the same time, permitting the tray or table 20 to be detached from the forward ends of the arms to swing downwardly into the posi tion indicated in dot and dash lines in Fig. 1, this operation being accomplished through side supporting and clamping links 2|. The links 2| are in the form of rather substantial rods, to one end 22 of which are pivoted two brackets 23 secured to the lower surfaces of the tray or table at inner side corner portions thereof, as clearly seen in Fig. l of the drawing. The other ends of the links or rods 2| are provided with enlargements or ball ends 25 which retain the same against displacement from clamp brackets 25 secured to outer edges of the seat in adjacent the forward corner portions thereof, as clearly seen in Fig. L.

The brackets 25 comprising outwardly extending round-bearing portions 25 having heads providing swivel mountings 27 in the plates 28 of said brackets; the swivel mountings 21 are in the form of inwardly tapered heads. The bearings 2'6 are apertured, as seen at 28, to receive the links or rods 2i. The bearings 25 also support clamp screws 39 having milled or roughened heads it; It will be understood that, when the screws 30 are loosened, the rods 2| are free to slide through the bearings 26 and these bearings are free to swing in the plates 28 in moving the tray from the position shown in full position in Fig. 1 to the dotted line position of said frame or in adjusting the tray '20 to different positions on the arms l5. In tightening the screws to, the tray will be supported in any position of adjustment.

In Figs. 3-7 inclusive, I have shown another form of construction. In Fig. 3, 32 represents a tray or table similar to 20, 33 arms similar to the arms I5, 34 channel couplings, similar to the couplings l9. In this figure, 35 represents the forward portion of the seat which is shown in section; 36 represents rods similar to the rods 2!; 3'! are pivot brackets similar to the brackets 23.

Instead of providing the clamp screw construc tion shown in Figs. 1 and 2, I provide in Figs. 3-7

inclusive clamp elements 38 which are slidably supported in spaced bearings or keepers 39 formed from an elongated metal strip 40 secured to the lower face of the seat 35 and extending to the side edges of the seat as will clearly appear from a consideration of Fig. 3.

The strip 40 also has a pivot 4i secured centrally thereof on which is mounted a lock lever 42, the pivot end portion of which is provided with two cam surfaces 43 adapted to operate upon inner spaced ends of the elements 33, as clearly illustrated in Fig. 4 of the drawing. The lever has at its outer end a fingerpiece 44 facilitating operation thereof and this end of the lever has an angularly extending corrugated finger 45 adapted to operatively engage one of the rods 38, as clearly seen in Figs. 4 and 7 of the drawing, to retain the lever in a predetermined locking position, when the rods 38 have been forced outwardly into firm engagement with the links or rods 36 retaining the latter against shifting movement in the supporting bearings 45 therefor. One of the bearings 46 is shown in sectional detail in Fig. 6 of the drawing and has a portion 4'! extending into a supporting bracket 48 and retained against displacement therefrom by a nut or collar 49 while, at the same time, providing rotary movement of the bearing 46 in the bracket. bracket 48 is secured to the outer side edge of the chair and the bracket is of an oiTset construction, so as to extend the portion 41 of the bearing Each 46 to a position to receive the element 38 operating from the lower surface of the chair seat.

It will be understood that, when the lock lever 42 is swung outwardly from the position shown in Fig. 4, the cams 43 will free the inner ends of the elements 38, thus releasing all pressure on the rods 36 permitting said rods 35 to swing and slide freely in shifting the position of the tray or table 32 or in swinging the same into a lowered position in the manner of swinging the tray 20 as in Fig. 1.

One advantage of the construction shown in I Figs. 3-7 inclusive is that the lock or control element constitutes a single member and is at a position out of any possible reach by a child and, in a single operation, both against movement, whereas in Figs. 1 and 2, each element 3! must be operated to lock or loosen the rods 2!.

Having fully described my invention, what I rods 36 are locked.

claim as new and desire to secure by Letters Patent is: v
