3 Claims.

This invention relates to arm chairs or lounges of the type in which the inclination of the back can be adjusted by sliding the arm rests supported on the side frames of the chair, and an object is to improve the mechanism or device for making such sliding movement possible and locking or securing the arm rest and the back frame in the position of adjustment.

Other objects and advantages of the invention will hereinafter appear, and for purpose of illustration but not of limitation, an embodiment of the invention is shown on the accompanying drawings in which Figure 1 is a side elevation of a chaise lounge constructed in accordance with this invention;

Figure 2 is an enlarged side elevation with some parts broken away, showing the arm rest and associated adjusting parts for varying the inclination of the back frame;

Figure 3 is an enlarged View substantially on the line 33 of Figure 2 with the elements I 8 and I9 removed for purposes of illustration;

Figure 4 is an enlarged transverse sectional view on the line t4 of Figure 2; and

Figure 5 is a view similar to Figure 4, but showing the arm rest raised to effect the adjusting movement.

The illustrated embodiment of the invention comprises a chaise lounge C which has a seat frame I0 of metal tubular structure and a back frame I I which is pivotally connected to opposite sides of the seat frame by pivots IZ. As shown, suitable cushions are mounted on the seat and back frames, as is customary in this connection.

On opposite sides of the seat frame ID are upwardly extending arched side frames I3 of metal tubes which are suitably welded to the seat frame as will be readily understood. An extension I4 of each side frame I3 projects downwardly and rearwardly, and provides a support for rubbertired supporting wheels l5. Formed in the top face of each of the arched side frame members I3 is an elongate slot It in which are formed at equidistantly spaced intervals a series of round holes I1, each hole being split in the center by the elongate slot, as is best shown on Figure 3.

Fitting rather loosely over the upper portion of each of the arched frames I3 is an arm rest I 8 of channel form and suitably fixed by welding or riveting to the under side of each arm rest is a band iron arm I9 which extends rearwardly and is pivoted to the adjacent side of the back frame II by a pivot 28. Fixed to the under side of the arm I9 substantially midway between the ends of each arm rest I8 is a stud rivet 2| as shown in Figures 4 and 5. The body of the stud rivet 2| 2 is round and of a size to fit readily in any one of the holes I1. Integral with the stud rivet M and depending therefrom is an extension 22 formed so as to slide freely in the elongate slot I6. An

elongate helical coil spring 23 has one end anchored to the lower or apertured end of the stud extension 22 and the opposite end attached to an anchor rivet 24. As shown, the spring 23 lies within the tubular frame part I3.

It will be understood that although only one side of the frame has been described, that this is duplicated on the opposite side. However, it is believed that the structure will be entirely clear since such an arrangement is conventional with furniture of this character.

In use, it will be understood that by lifting up on the arm rest I8, the round stud portion 2| can be lifted clear of the hole ll in which it rested, and then the arm rest can be moved forwardly or rearwardly in accordance with the inclination desired of the back frame II, the extension 22 sliding in the slot I6 freely. When the desired position has been selected, then each arm rest is pushed downwardly to force the round stud portion 2! into the adjacent hole I1 whereby it is locked in position. The coil spring 23 aids in the raising of the back frame II so that when it is desired to have the back frame more erect, the coil spring will assist substantially in that connection. It will, of course, be recognized that when the back frame II is swung rearwardly toward its horizontal position, the coil spring 23 is placed under tension so that it is capable of assisting in the raising of the back frame, as will be readily recognized.

It is to be understood that numerous changes in details of construction, arrangement and operation may be effected without departing from the spirit of the invention especially as defined in the appended claims.

What we claim is:

1. In a reclining chair or the like, the combination of a seat frame, a back frame hinged to the seat frame, a side frame of tubular construction affixed to the seat frame, said side frame having an elongate slot and a series of holes intersecting said slot, an arm rest disposed over a portion of said side frame and articulated to the back frame, a stud rigidly depending from said arm rest and shaped to conform to said holes for selective engagement therewith, said holes being larger than said stud and an extension depending from said stud on the side thereof opposite said arm rest and shaped to slide through said slot when the arm rest is sufficiently raised to remove the stud from the respective hole.

2. In a reclining chair or the like, the combination of a seat frame, a back frame hinged to the seat frame, a side frame of tubular construction afiixed to the seat frame, said side frame having an elongate slot and a series of holes intersecting said slot, an arm rest disposed over a portion of said side frame and articulated to the back frame, a stud rigidly depending from said arm rest and shaped to conform to said holes for selective engagement therewith, said holes being larger than said stud an extension depending from said stud on the side thereof opposite said arm rest and shaped to slide through said slot when the arm rest is sufficiently raised to remove the stud from the respective hole, and a spring engaged between said side frame and said stud adapted to be tensioned when the back is swungrearwardly' tion of a seat frame, a back frame hinged'to the seat frame, a side frame of tubular construction afiixed to the seat frame, said side frame having an elongate slot and a series of holes intersecting said slot, an arm rest disposed over a'portion of 25 Number said side frame and articulated'to the back frame,

a' stud rigidly depending from said arm rest and shaped to conform to said holes for selectiveengagement therewith, said holes being larger than said stud an extension depending from said stud on the side thereof opposite said arm rest and shaped to slide through said slot when the arm rest is sufiiciently raised to remove the stud from the respective hole, and a spring adapted to be tensioned when the back is swung rearwardly toward horizontal position thereby to assist in swinging same toward upright position, said spring disposed within the tubular side frame and anchored at one end to said depending stud extension, and means to anchor the-opposite end of said spring.
