To aZ-Z 'whom t may concern. j

Be it known ythat l, SOMA HERZOG, a citizen of the United Stat-es, and resident of the borough ot Manhattan, city, county, and State of ,New York, have invented certain new and useful Improvements in Chairs, of which the following` is a specification.

My invention relates to chairs and has for its object to provide a convertible chair of simple and improved construction and arangement. Other more specilic objects of my invention will appear from the description and the features of novelty will be pointed out in the appended claim.

Reference is to be had to the accompanying drawings, which, tor illustrative and descriptive purposes, show two forms ot my invention and in which Figure 1' is a perspective view of one form of my improved chair; Fig. 2 is a central vertical section thereof; Fig. 3 is a similar view showing said chairconverted 'for use as a step-ladder; Fig. 4 is a rear view; Fig. 5 is a side elevation showing another form of my improved chair; Fig. 6 is a rear view thereof and Fig. 7 is an elevation showing said chair converted into a wheel-barrow or the like.

As shown` in the drawings the4 chair comprises a seat 10 and` iront supporting members or legs 11 rigidly secured thereto; in order to increase the rigidity of the construction the customary rungs or cross pieces 12 may `be provide-d between said front members in thewell known way. Rear members or legs 13 are pivotally connected to the seat 10 at 14. and are continued upwardly beyond the same as'shown, for instance, in Figs. 1 and, the members 13 being connected by means oirungs or the like 145 locatedat spaced intervals throughout the length of said rear members13. rllhe rangs 15 may be of rectangular cross section as in Figs. 2 and 3 or they may be ot circular cross section as in Figs. 5, 6 and 7, it being understood that in some cases said rungs be oit still other cross sectional terms.

' In both oi2 theillustrated forms ot my chair the rear members 13 and rangs 15 togetherjtorm a rear trame which is capable ot pivotal `movements relatively to the seat 10 about the pivots 14. ln each case the seat 10 or some other appropriate portion of the chair is provided with one or more inclined shoulders 1G and vertical shoulders 16aL arrangedin the pivotalpaths of the rear members 13 and adapted to engagethe same to arrest the pivotal movement ot said rear yshown iixed and steadied thereby in said inclined position. ln the `form shown in Figs. 5 to 7 inclusive the rear frame is pivotally movable in the opposite direction to the posit-ion shown in Fig. 7 in which the shoulders 16 engage the rear members 13 to securely brace the same in the inclined position indicated. ln both forms the vertical shoulders 1GEL engage the rear members 13 and brace the same in their normal upright positions.

Referring now more particularly to the term shown in Figs. 1 to 4 the chair includes a panel 17 pi-voted at 18 between the rear members 13 near the upper ends thereot. llhen the chair is in the normal condition shown in Fig. 1 this panel 17 may depend from the pivots 18 between the members 13 to form the back of the chair.; or said panel 17 may be swung to the horizontal position shown in Fig. 2 in which it rests, for instance, upon the uppermost rung 15 and projects rearwardly from the chair. In this condition the panel may be used as an invalids table to extend over a bed or as a table to be used by a person straddling the chair. rEhe panel 17 may also' be brought to the position shown by `full llines in Fig. 3 in which its tree end` rests upon the seat 10; in this position the panel forms a brace whereby the rigidity or the'rear frame in its inclined position is increased. To prevent slipping ot the panel upon said seat 10 a latch 19'may be slidably carried by said panel, saidr latch, in its operative position extending into notch 2Ov formed in the chair seat 10. ln addition to the above the panel. 17 may be adjusted to the position by dotted lines in Fig. 3 in which it serves as a shelf whenthe rear trame occupies the inclined position shown. The panel 17 may be maintained in the indicated dotted position in any suitable manner as by means of lugs 2l pivoted to the panel and extending beneath the upper rungs 15 in their operative positions. 'llhelatch 19 and the lugs 21 are all movable to inoperative positions in which ythey lie entirely within the panel 17 when not required.

This form of chair includes further a brace comprising members 22 pivotally connected at 23 to the front supporting members 11 and having hooks 24 and a projection 25 adapted to coperate with a cross bar 26 extending between and connected with the rear members 13. The cross bar 26 is preferably provided with recesses 27 for the accommodation of the members 22 when the hooks 24 are used and with a notch 28 for coperation with the projection 25 when the latter is used.

When the rear frame is in its normal condition as shown in Figs. 1 and 2 the hooks 24 lie behind the bar 26 and thus maintain the rear members 13 in contact with the shoulders 16a and against pivotal movement. `When in theinclined position shown in Fig. 3 the shoulder 25 lies behind the bar 26 in registry with the notch 28 thereof whereby the brace 22 holds the rear members 13 rigidly in their inclined positions against the inclined shoulders 16.

In the form shown more particularly in Figs. 5, 6 and 7, the chair includes also a panel 17a pivoted at 18a between the rear members 13 and in its normal position depending from said pivot 18a between said members 13 to form the back of the chair as shown in Fig. 5. The panel 17EL is adjustable to a horizontal rearwardly eXtending position indicated by the dotted lines a in Fig. 5; in this position said panel may be used as a table in the same way as indicated with respect to the form shown in Fig. 2. In the form being described the panel 17il is maintained in the position a by means of a lug 29 projecting outwardly from the upper rung 15av which in this case is rotatably mounted between the rear members 13. A pair of members 30 are connected with the rung 15a and project therefrom in directions opposite to that in which the lug 29 extends; these members 30 by their weight normally maintain the rung 15a in a position in which the lu@` 29 extends upwardly to form a rest fbr the panel 17a when it occupies the dotted position a. By swinging the members 30 rearwardly the lug 29 is removed from beneath the panel 17a which is thus released and may assume the inclined position indicated by the dotted lines 5 in Fig. 5. In this position the lug 29 and members 30 extend lengthwise beneath the panel 17a and provide a rest whereby the panel is maintained iii the inclined position 5,' when thus adjusted the panel 17a may be used as an easel or as a blackboard, in which case the one surface thereof may be covered with silicate or otherwise treated to provide a writing surface which may be Y yreadily cleaned.

The form at present being described includes also a wheel 31 carried by the lower rung 15b which is also rotatably mounted between the rear members 13; in the normal position of the chair this wheel 31 does not contact with the surface upon which the chair stands as shown in Fig. 5. By adjusting the rear members 13 to the inclined position shown in Fig. 7 and by swinging the members 30 outwardly beyond said rear members 13 as shown in said figure, the members 30 may constitute handles whereby the chair in this condition may be trundled land cooperating pins 36 which prevent the joints from breaking downwardly and permit said joints to break upwardly without interference when the rear members 13 are adjusted to the position shown in Fig. 7. rIlhe braces, in their normal positions shown in Fig. 5, lock the rear fraine or rear ineinbers 13 in their normal upright positions against pivotal movement.

Both forms of my chair are simple in construction and may be easily converted to serve different purposes. For instance, the chair in Fig. 3 becomes an eflicient step ladder while the chair in Fig. 7 becomes a wheel conveyance from which a child may derive amusement as a toy or which may be practicall7 used for conveying purposes.

I arious changes in the specific forms shown and described may be made within the scope of the claim without departing from the spirit of my invention.

I claim:

A convertible chair comprising a seat, front legs rigidly connected therewith, a rear frame pivotally connected with said seat and extending below thesame to form rear legs and above the saine to form back posts, a panel freely pivoted between the latter out of engagement with said seat to constitute in its normal position, the back of the chair,V

said panel being movable into engagement with said seat to prop said rear frame in an inclined position relatively to said seat and being movable to a horizontal position extending rearwardly of said rear frame to form a table and means on said seat coperating with said rear frame to determine its normal upright position and its inclined position with respect to said seat.

In testimony whereof I have hereunto set i my hand.

SOMA HERZOG.
