. 4 Claims.

This invention relates to furniture and more particularly to a combined. .chair,.s.tool andjladder.

.Among the objects of the invention. is the provision of a kitchen accessory comprising a chair of conventional height that may be converted into a stool of greater height, for convenient use at the kitchen sink, laundry equipment and the like.

Another object is :the proyisionof such @achair assembly having a .foldable ladder therein, :for use in reaching the hi her shelves, curtain .installations and other household equipment. 7

' A further object is the provision of sucha uti ity that is IighEsturdY, comfortablqsafe and attractive, that .can be fabricated at a relatively low cost.

Other objects and advantages will appear as the .-.description progresses. In the specification and the-accompanying drawings the invention is disclosed in its preferred form, But it is to be understood that it is not limited to this form; because it may be embodied in modifications within the spirit of the .invention, as defined in the claims following the description.

' In the one sheet of drawings:

Fig. 1 is a perspective front view of a chair assembly constructed in accordance with this invention.

Fig; '2 isa similar side ,view of the same with the ladder in operative ,positiQn.

3 is ,a similar view of the same from the rear.

Rig. 4 is .a fragmentary detail, similar to Fig. 1, with the stool removed from the chair.

Rig. .5 is an enlarged detail from the side, in vertical section, showing the pin and latch engagement of the stool seat with-the chair.

In detail the structure shown in Fig. 2, com.- prises the:interspaced sides .I, 2, having the legs 3, .4, 5, .6 :andthe hackrails :1, vii, respectively. These, sides are joined in the middle of their length by the transverse seat 9, braced by blocks in thecorners beneath the seat and not visible.

The back board I is attached to the back rails I, 8 and extends upwardly from the seat 9. This back has the upper opening ll, forming a convenient handle portion 12, and the lower transverse notch, forming a slot l3 above the level of the seat 9.

The front legs are cross braced by the rung l4, and the rear legs by the rung I gained thereinto and glued respectively. The seat portion is reinforced by the front trim l6, Fig. 4, inset and glued similarly to the rungs l4, 15. This forms a strong, light and rigid chair foundation for the other elements of the assembly.

Application-October 11, 1947 ,-Se rial No. 719,296

has the central block 25,, having the stud 26 'pro-' jecting downward into the socket ll in'the'front edge of the seat 9, see Fig. 5. The front '20 of the stool rests upon and is anchoredto the seat 9 at '26, and to the back H) at 24, beneath the detent in where it remains. "The latch 20" and detent l0 lock thestool [8 in the elevated position so that it will not be displaced if the chair is lifted or moved about by grasping the stool portion of the assembly.

When itis desired to lower the stool, the user releases the spring latch 20' engaging beneath the stop 16' on the front trim l6 and grasps "the front 20, through the opening 21, lifts the stool assembly free at 2-6 and H, and lowers it to the. 7

seat level 9 and pushes the tongue 23 into the slot 13 and lowers the front until the sides 2|, 2-2 bear against the sides [,2 of the-chair frame and the stud 29 on thestool l8 enters the socket I! in the front of the seatas previously described relative to the .stud 26. This .secures the stool assembly to. the chair foundation. .The cushion 28 is attached to the top .of the stool.

The ladder element comprises .the side rails :30, 31,havingthe'friction inserts .30, 3|, in their lowerends respectively, and joined together Jay the steps 32, 33,34, in the usualmanner- These rails extend slightly above the top step .34, and have the "laterally extending pivots 35, .36, respectively extending into the.slots;31, 38 through theupper portions of thefibackrails 'I, 8. "These. vertical slots have lateral extensions, 39, .40 -re-,

spectively extending toward the back ill of the chair, into which the pivots lock when the ladder is in the extended position, as in Figs. 2, 3.

The lowest step 32 has the depending keepers 4|, 42 attached to blocks fixed beneath the step, adapted to hook over the top edge of the rung l5, into the notches provided therein. The inner edges of the side rails are recessed at 43, 44, to

pass the width of the rung 15, when the ladder,

is retracted.

The ladder is retracted by grasping beneath the top step 34 pulling it backward to clear the extensions 39, 40, then lifting the ladder, which is guided by the pivots 35, 36 in the slots 31, 38.

The ladder is then swung inwardly on these pivots and the keepers at 4|, 42 dropped over the notched top of the rung 15, which holds the ladder assembly closely telescoped within the width of the back rails 1, 8, and the rear legs 5, 6, of the chair, as in Fig. 1.

When the ladder is in the extended position, as in Fig. 3, the top step 34 is adjacent the bottom 24 of the opening II in the back of the chair, so that the toe of the user may extend beyond the front edge of the step and through the opening in the back Ill of the chair, for greater foot security.

The legs 5 and 6 have the rearward extensions 5, 6' respectively, for giving stability to thee tended ladder, as in Figs. 2 and 3, affording better support on the center ofgravity --when theuser is standing thereon.

The front legs have similar forward extensions 3, 4 respectively, preventing the chair rotating and stiffened by embossing, plastics, or any other suitable materials; in substantially the same design and mode of operation. V
