will fold into a compact package for storage or trans- I porting.
It is still a further object of this invention to provide a childs high chair which may be rapidly converted to a kitchen chair Without removal of any parts.
it is a further object of this invention'to provide such a convertible chair which is rugged and durable and easily operated.
Other objects of this invention will be readily apparent from the following description:
In the drawings:
FIGURE 1 is a perspective view of a high chair embodying this invention.
FIGURE 2 is an enlarged side elevation of the chair.
FIGURE 3 is a side elevation of the chair partially folded.
FIGURE 4 is a side elevation of the chair in the folded position.
The chair comprises a pair of front legs 10 and 12 and a pair of rear legs 14 and 16, each front leg crossing a rear leg and being pivotally connected thereto by a pin such as 18. A lower brace 20 interconnects each pair of legs to provide stability.
Mounted upon each front leg above its pivotal connection to the rear leg is a bracket 22. A U-shaped seat frame 24 has its extremities 26 pivotally connected to said brackets 22. An upholstered seat 28 is suitably mounted upon seat frame 24. The front legs above brackets 22 are bent slightly as at 30 and are joined together at the top so that the front legs may be formed of a single piece of tubing having a closed U-shaped upper extremity upon which upholstered back rest 32 is suitably fixed.
The rear legs likewise are formed of a single tubing bent so as to form a U-shaped closed extremity as at 34, from which the rear legs depend at an angle formed as at 36. A pair of brackets such as 38 have one extremity pivotally connected to seat frame 24 and the other to one of the rear legs 14 so that the chair may be folded and so that the upper extremity 34 of legs 14 will abut bracket 40 on the frame 24 when the chair is in the unfolded position preventing further forward movement of same.
An adjustable footrest 42 is pivotally mounted upon brackets 38 by rods 44 each pivotally mounted at one extremity to a bracket 38 and rigidly secured to the footrest 42 at the opposite extremity. The footrest is preferably formed of suitable plastic and has a pair of spaced brackets 46 mounted on the underside thereof. Each bracket has a slot 48 therein with a series of grooves 50 formed therein. A U-shaped rod 51 is pivotally mounted at each end thereof to a rear leg 14 or 16 and fits into grooves 50 to permit adjustment of the footrest as desired.
Projecting forwardly from front legs 10 and 12 adjacent back rest 32 are a pair of arms 52 and 54. The forwardmost extremities of each arm are bent downwardly in FIGURES l and 2 and fit into a U-shaped strap 56 or 58. A U-shaped locking and bracing element 60 is secured also into straps 56 and 58 and when the chair is unfolded engages bracket 40 which has a forwardly projecting portion 62 for this purpose. Seat 28 overhangs the element 60 when the high chair is in the unfolded position preventing upward pivoting of element 60 and arms 52 and 54. The arms 52 and 54 each carries a sleeve 64 thereon and each of which receives an extremity of tray supporting arms 66 which in turn sup- 7 port tray 68. Arm 52 carries a spring loaded detent 69 which projects into one hole of several in sleeve 64 to permit adjustment of tray 68 relative to the back rest.
In use the chair may be unfolded to the position in FIGURE 2 to serve as a high chair. If it is desired to fold the tray out of the way to the phantom line position of FIGURE 2 to use the chair for purposes other than a high chair the chair is partially folded to the position of FIGURE 3 permitting the locking and bracing element 60 to clear the edge of seat 28. After then pivoting the tray frame formed by arms 52, 54 and U-shaped locking element 60 may be pivoted upwardly clearing the top of seat 28 permitting same to hang in the phantom line position. When it is desired to again use the chair as a high chair tray 68 is pivoted forwardly over back rest 32, the legs partially folded to permit locking element 60 to clear seat 28 and rest on bracket 40.
To facilitate folding of the high chair locking element 60 is rigidly secured to U-shaped straps 56 and 58 while arms 52 and 54 are pivotally connected to said straps by pins such as 70. Thus the locking element may be pivoted beneath tray 68 when the chair is fully folded to facilitate folding as seen in FIGURE 4.
While what hereinbefore has been described as the preferred embodiment of this invention, it is readily apparent that alterations and modifications can be resorted to without departing from the scope of this invention and such alterations and modifications are intended to be included within the scope of the appended claims.
