7 The present invention relates to means or devices for preventing the} accidental toppllng over of chairs, stands and the l1ke; and

V the purpose of the invention is to provide antomatic means of thisfkind, which are simple of construction and lnstantaneously operativewhen requlred,

According to the present invention, the improved means conslsts' of one or more props 10 or auxiliary legs'cap'able of being applied to chairs, particularly high chairs for infants; but the; invention may be used with equal advantage with vsmoking stands, and numerous other articles of a similar nature, which stand on three or more legs and are apt to topple-over; i i

In carrying out the invention, the improved means comprise as stated, one or more props or auxiliary legs, which are properly secured to the frame of the chair or stand These legs are hinged so as to open outwardly and the opening of the legs is efiected under action of a spring. These legs are each held in the closed position by a latch,rwhich is automatically released when thechair, for example, it tilted intoan angular position. When the chair'is tilted the released auxiliary legor prop is instantly thrown'to its full open position, so that the chair is caught and held in a tilted position beyond the center of gravity.

It hasprevlou'sly been "proposed to emc ploy props or auxiliary supporting members swingin' outwardly fromchairs or stands for holdlng the same in an extreme tilted po-v sition, but heretofore such devi'ces'have been so arranged and constructed that they have to be set by hand into the operative position, or they'are swung into that position by grav-' ity; and-ineither instance the additional leg or' prop is apt to be ineffective, when the chair, for example, is suddenly tilted to an an- "gular position beyond the center of gravity.

. V 1 drawing wherein: v r a v Figure 1 is a side elevation of a'high chair, I the same being shown by full lines in the perpendicular position, and by brelgen lines V in a supported tilted position;

vThe invention will be hereinafter fully de-: I scribed, with reference to the accompanying Figure 2'is a'plan viewsh'owing'the aux-,

iliary legs orprops in the open position; and

"These legs'fi'have feet 7 extended so as to provide a broader supporting base, and said legs '6 arehinged atS to the underside of the memberfof the chair constituting the seat. Preferably-a spring hinge is employed,and-inaddition to this springhinge, a leaf spring 9 may be employed so as to secure a quicker spring action .to open the legs when this is required. Each leg 6 is braced by a folding member 10, which slides under a guide plate 11 secured to the leg 6. Each leg 6'has a pawl 13, which is engaged by a latching device 12 carried on V a tripping member 14, the latter being pivotyond-a determined point, the ends of the tripping device will be engaged with the floor so thus releasing the latch, and the auxiliary leg ally connected to lug 15. vThe tripping In the operation of theimproved device,

T that said tripping device is forced upwardly,

associated therewith. The prop'so released will instantly flyoutwa-rdly and thus catch and support the chair, so as to prevent its toppling over. The tripping device is'con-' structed and arranged so thats hould a 7 Chair, for example, be tilted in "adiagonal angular position, two of the tripping devices would be operated, thus a pair of the aux iliary legs would be thrown into operation so that the safety support for the chair would I 1 effective along the line 16, shown in i re 2.

construction and application of the invention hereinbefore described and it is to be understood any modification coming fairly Within the terms of the appended claims shall be covered thereby.
