CHAIR WITH A COLLAPSIBLE FOOTREST Jay R. Martin, Chicago, 11].

Application February 6, 1952, Serial No. 270,144

6 Claims. (Cl. 155-171) My invention relates to certain new and useful improvements in a chair with a collapsible foot rest and has as an object the provision of a simple, inexpensive and eflicient chair with a collapsible foot rest and one which is capable of being readily arranged in position for use and capable of being compactly collapsed when not in use.

Another object of the invention is the provision of a chair with a foot rest of the character hereinafter described, which upon simple operation requiring the minimum degree of effort can be extended or collapsed by the occupant of the chair.

Another object of theiuvention is to provide a simple and effortless assembly with no visible means of operation whereby the occupant of the chair may, without materially changing his position, raise or lower the foot rest as desired.

Other objects will appear hereinafter.

The invention consists in the novel combination and arrangement of parts to be hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings showing the preferred form of construction, and in which:

Fig. 1 is a perspective view of the invention showing the same in collapsed position;

Fig. 2 is a sectional detail view of the invention taken substantially on line 2-2 of Fig. 3;

Fig. 3 is a side sectional view of the invention taken substantially on line 33 of Fig. 2, showing'the chair with the foot rest in collapsed position;

Fig. 4 is a view similar to Fig. 3 showing the mechanism in one position of its operation; I

Fig. 5 is a View similar to Fig. 3 showing the invention with the foot rest in extended position.

The several objects of this invention are accomplished by the preferred form of construction shown in the accompanying drawings. In this connection achair is indicated at 10. This chair may be of any desired design or configuration and will best serve the purpose.

Such chair comprises a hollow frame having a back rest 11, a seat portion 12, and a foot rest 13. Attached to each side of the back rest 11 are

arm rests

14 and 14. The arm 14 is fixed to a rotatable rod 15 and assuch is adapted to be pivoted at its point of connection in a substantially upward direction for the purposes hereinafter described. Downward movement of the arm 14 beyond a certain point is prohibited by a stop 15' carried by thev hinges 16. These hinges are set in recesses 17 in the nited States Patent 0 F ice peripheral edge of the foot rest 13. Connected to the foot rest 13 and the front wall 22 of the chair 10, is a spring 16' adapted to urge the foot rest 13 in an extended position.

Pivotally connected as at 18 to the underside of the foot rest 13 is a U-shaped supporting bar 19 having its end portions 20 extending through slots 21 in the chair front 22.

The understructure of the chair 10 comprises a horizontal mounting bar 23 having a recess 24 cut in its upper edge. At the center of this recess 24- and extending diagonally upwardly and rearwardly therefrom is a notched-out portion 25. Hingedly secured in this notched-out portion 25 is a V-shaped receiving bracket 26, into which the bar 19 is adapted to slide when the foot rest 13 is in an extended position. Attached to the mounting bar 23 is a center supporting bar 27 extending rearwardly to its point of attachment to a second supporting bar 28.

Cut in the upper edge 30 and in the middle of the center supporting bar 27, is a notch 29, into which the U-shaped bar 19 is adapted to be retained when the foot rest 13 is in collapsed position. It is upon this upper edge 30 that the annular bar 19 rides in its movement outwardly, when the foot rest 13 is extended. Pivotally located, as at 32, to the side of the center supporting bar 27 and beneath the notch 29, is a triangular shaped release trigger 31, which when operated will move the bar 19 out of the notch 29. This release trigger 31 is connected at one end by any suitable means, such as the cord arrangement 33 shown for illustrative purposes herein, through a pulley 34, to the V-shaped receiving bracket 26; and at the. opposite end through a pulley 35, carried by a supporting bar 36, and attached to a connecting member 35' carried by the rod 15.

The operation of the chair with its foot rest mechanism is as follows, starting with the foot rest in its collapsed position:

The occupant of the chair who wishes to extend the foot rest 13, will raise the arm 14, which in turn will rotate the rod 15, pulling the cord 33 taut. The pull on the cord 33 will pivot the trigger 32 upwardly which Will move the bar 19 out of the retaining notch 29, and the foot rest 13 under. action of the spring 16' will be forced upwardly, pivoting on its hinges 16. The bar 19 will ride on the edge 30 of the center supporting bar 27 through the slots 21 in the chair front 22 and be guided into the V-shaped receiving bracket 26, which is also pivoted downwardly by the pull on the cord 33, as viewed in Figs. 4 and 5. Upon engagement of the bar 19 the receiving bracket 26 will pivot on its hinge to an upright position as shown in Fig. 5, and the bar 19 will from the pull of gravity fall into the recess 24 where it will become held from movement, with the foot rest '13 in its extended position. The complete action may be followed by reference to Figs. 3 through 5.

To collapse the foot rest 13, the occupant snaps the arm 14 upwardly, thus pulling the cord 33 and through the,

pulleys

34 and 35 this motion is transferred to the V-shaped receiving bracket 26, causing it to pivot backwardly. Upon the pivoting of the receiving bracket 26, the bar 19 is raisedslightly so as to be on the same level as the top edge 30 of the center supportingbar 27. The occupant then returns the arm 14 to its original'position, and with slight downward pressure of his legs 3 forces the foot rest 13 down,,the bar 19 moving backward until it falls into the notch 29 where it is retained in collapsed position.

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. 1, therefore, do not wish to be limited tcir the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having thus described my invention, what I claimas new and desire to protect by Letters Patent. isz
