3 Claims.

is compact and durable in construction and which is, moreover, fool-proof and safe in use;

To provide an improved highchair having a conveniently adjustable table provided with a safety strap for preventing the infant from falling out of the chair; I

To provide improved adjusting mechanism for the table of an infants chair, whereby any degree of adjustment of the table may be readily procured, and wherein the table is effectively locked in various positions of adjustment;

To provide an chair is entirely eliminated, and which may be maintained in a highly sanitary condition;

To provide an improved high chair table structure adapted to efiectively confine a plate or tray, and which is extremely neat in general appearance;

To provide a chair structure which can be readily manufactured at moderate cost, and which is extremely safe during normal use and when the occupant of the chair is being removed therefrom. 7

These and other objects and advantages will be apparent from the following detailed description.

A clear" conception of an embodiment of the present invention, and of the mode of constructing and of utilizing high chairs built in accordance therewith, may be had by referring to the drawing accompanyingand forming a part of this specification, in which like reference characters designate the same or similar parts in the various views.

Fig. 1 is a central, vertical section thru an assembled high chair, showing the table in full lines adjusted inwardly as far as possible, and

also showing this table in dot-and-dash lines adjusted outwardly as far as possible, and also improved chair structure wherein danger of injury to the occupant of the high chair, showing the normally concealed bottom portion of the table, which has been swung into uppermost position;

Fig. 3 is a fragmentary bottom View of one end of the table, showing the adjusting and 5 locking mechanism therefor; and

Fig. 4 is a transverse section thru the table taken along the line 44 of Fig. 2, and showing a fragment of the supporting bar for the table.

While the present invention has been illustrated and described herein as being specifically applied to an infants high chair, it is not in tended to limit the scope by such specific disclosure since some of the novel features may obviously be more generally applicable to other types of chairs.

Referring now more particularly to the drawing, it will appear that the high chair, especially adapted for infants and small children, comprises a seat 8 suitably supported by elongated legs 9. The rear portion of the seat carries the usual upwardly projecting back rest III, while side posts II support side arms I2 connected at their inner ends with some of the back elements.

A pair of rearwardly, upwardly curved tablesupporting rods I3 have their rear ends pivotally attached to upper side portions of the back support, as at M. Adapted to be adjustably carried by the forward, straight portions of said rods is a table l5, and in normal position said table spans forward portions of the arms I2; and. the

rods I3 are located outwardly, laterally thereof.

To effect the adjustable connectionbetween the table I5 and the outer ends of the rods I3, the table, adjacent itsside edges, is formed with a pair of transverse recesses I6, extending from the inner edge of the table forwardly, as best shown in Fig. 4. The outer ends of the rods I3: project into said recesses, and the table is, therefore, slidable with respect to the rods for adjustments inwardly or outwardly with respect to the chair.

The underside of the table I5, adjacent the recesses I6, is formed with slots II. Thru said slots project headed studs !8 which'are secured to outer end portions of the rods I3. Hence, when the table is adjustably moved on said rods, there is relative movement of the studs I8 in said slots. Adjacent the inner end of each slot there is pivotally secured to the inner face of the table, the inner end of a latch plate I9. One side of each latch plate is provided with a series of notches or serrations 29 for selective engagement with the shank portion of a stud I8. Springs 2|, anchored at one end to the table, as

, against the force of the springs 2i.

at 22, are secured at their other ends to the free ends of the plates i9, whereby said plates are pivotally movable against the force of the springs.

The top face of the table 55 is provided with a recess 23 to removably receive a suitable dish or tray 24'. With this arrangement, an attractive enameled dish or the like may be mounted in the upper portion of the table, and it is readily removable for serving and cleaning.

To prevent a child from slipping out of the chair, and to releasably hold the table assembly in normal horizontal position, a retaining strap 25 is provided. Said strap is permanently secured at one end to a front intermediate portion of the seat 8, while the other end portion of said strap carries a male fastening element 26. A slotted female fastening element 277 is secured to the underside of the table member, and when the table is in any horizontal position of adjustment, the element 25 may be releasably engaged with the element 2? thru the enlargement of the slot 28 therein.

In use, the table may be swung with the rods l3 to an upright position, as in broken lines in Fig. 1; and this position permits entrance and egress to and from the seat s, it being understood that such movements may only be efiected when the strap 25 is released. After a child has been placed in proper position in the chair, it maybe desirable to adjust the table either inwardly or outwardly with respect to the chair occupant. This may be accomplished in either the raised or lowered position of the table. To effect an adjustment, both of the latch plates is are pivotally swung to positions out of engagement with the studs 58, such movements being Then, the table may be slid forwardly or rearwardly a desired distance on the rods 83. Finally, the latch plates are released and the springs urge them toward engaging positions, and by slight manipulation, the studs !8 can be caused to register with proper notches 29. In this way the table will be releasably locked in any desired position of adjustment. When the chair is occupied, and after the table has been adjusted, the retaining strap should be engaged in holding position for the puiposes heretofore noted.

"The removable dish or tray 2 also forms a highly desirable feature. It is readily removable for serving purposes and for washing, and when mounted, the recess 23 holds it against undesired easy dislodgment. 1

From the foregoing description it will be seen that the improved chair structure is both simple and novel and is well adapted for the purposes described.

What I claim is:

arms, a table adapted to rest upon said arms forwardly of the occupant of the chair and having transverse sockets therein and slots communicating with said sockets, side rods pivotally connected at one pair of ends with portions of the chair and having their other end portions extended into said table transverse sockets, there being relative sliding movement between the table and the latter rod end portions for table adjustments, studs carried by said latter rod end portions and projecting thru said slots, and latch plates pivotally mounted on the table and having means for selectively engaging projecting portions of said studs.

2. In combination with a chair having side arms, a table adapted to rest upon said arms forwardly of the occupant of the chair and having transverse sockets directly therein and slots communicating with said sockets, side rods pivotally connected at one pair of ends with portions of the chair and having their other end portions extended into said table transverse sockets, there being relative sliding movement between the table and the latter rod end portions for table adjustments and said rods and table being swingable relative to said arms, studs carried by said latter rod end portions and projecting thru said slots, latch plates pivotally mounted on the table and having a plurality of notches which are releasably selectively engageable with projecting portions of said studs, and springs connected to said plates and table and restricting movement of the former.

3. In combination with a chair having side arms, a table adapted to rest upon said arms forwardly of the occupant of the chair, said table having transverse sockets therein from its inner 'edge inwardly and slots on the bottom face of the table communicating with said transverse sockets, curved side rods pivotally connected at one end with portions of the chair and having their other end portions extended into said table transverse sockets whereby the rods and table are swingable relative to said arms, there being relativesliding movement between the table and said latter rod end portions for table adjust- 'ments, studs carried by said latter rod end por- FREDERICK W. BRAASCH.
