7 Claims. 1

This invention relates to chaise lounge and the like articles of furniture having a back rest pivotally supported with respect to a seat section so that it may be swung from an upright position to a horizontal position and held in a selected position of adjustment.

In articles of furniture of the above type the occupant often desires to change or adjust the position of the back, and most conventional constructions either provide notches for holding the back in one of a few positions of adjustment, or locking screws or nuts which must be well tightened in order to hold the back in the selected position of adjustment.

The principal object of the present invention is to provide an article of furniture of the above type which has a simple, efficient and reliable means permitting the occupant easily and conveniently to adjust the back while reclining on the seat and readily lock the back in the selected position of adjustment.

Further objects relate to various features of construction and will be apparent from a consideration of the following description and the accompanying drawings, wherein:

Fig. 1 is a side elevation of a chaise lounge constructed in accordance with the present invention;

Fig. 2 is a section on the line 2-2 of Fig. 1;

Fig. 3 is a view showing one type of back lock; and

Fig. 4 is a view similar to Fig. 3, but showing a modified type of back lock.

The embodiment herein shown for the purpose of illustration comprises a horizontal seat section I which may be of conventional construction, consisting of a rectangular angle iron frame which carries the usual slats, wire mesh, or the like, for supporting a mattress or cushion 2 which may also be of conventional construction. Each side member a of the seat section is supported adjacent to its front and rear ends by legs 5 and 5, the rear legs 5 preferably being in the form of curved extensions of the side members 4 and carry rollers or wheels 8 which permit the lounge to be moved from place to place. The back rest or section 3 is pivotally connected at 9 to the rear end of the seat section I so that it may be swung from an upright or substantially vertical position to a horizontal position in the plane of the seat section. The back section consists of a U-shaped angle iron frame It] carrying the usual slats H for supporting a cushion l2 which is preferably connected with the cushion 2, as indicated in Fig. 1, so as to provide, in effect, an integral part thereof.

A generally L-shaped arm rest I5 is carried by each side of the lounge, the upper end of each arm rest being pivoted at It to a side member to of the back rest and the lower end of each arm rest is juxtaposed to the side members 4. The lower ends of the members l0 extend below the side members 4 and each is connected to one end of a tension spring N3, the opposite end of which is connected to a cross-bar 20 secured to the legs 6. The design of the parts and tension of the springs I8 are such that the back rest 3 is normally held in upright position, as shown in Fig. 1, but when subjected to a slight pressure the back rest swings downwardly and may be locked in any desired position of adjustment by the mechanism presently to be described.

Mounted on the underside of each side member 4 and adjacent to l 5 are depending brackets 25 formed with aligned horizontal slots 26. A transverse bar or rod 28 extends from one bracket to the other with its end portions projecting through the slots 25 and openings in the arm rests l5. One end of the bar 28 carries a nut 36 and its opposite end is secured to a L-shaped lever 32, the free end of which is provided with an integral inwardly directed extension 34 (Fig. 2) engageable with the lower edge of the bracket to limit its swinging movement from one position to another. The

length of the slots 26 is such that when the back rest 3 is in fully elevated position the end portions of the bar 28 are at one end of the slots and when the back rest is swung downwardly to horizontal position the end portions of the barEt move to the opposite ends of the slots.

The intermediate portion of the bar 28 is preferably downwardly offset to permit depression of the cushion 2 by the occupant, and the portions 36 of the bar which pass through the slots 25 have a cross-section which is so shaped that when in one position they have a free sliding fit within the slots, but when rotated through an angle of the order of 45 they engage the opposite sides of the slots, exerting a binding action thereon which locks the parts in position. Such locking portions or cams 36 are preferably of square cross-section with flattened corners, as shown in Figs. 3 and 4, and the walls of the slots 26 may either be plane, as shown in Fig. 3, in which case friction alone is relied on for the locking action, or at least one wall may be serrated, as shown at 21 in Fig. 4, in which case a positive locking action is provided. In either case the bar 26, lever 32 and the arm rest I 5 move as a unit when the back rest is swung from one position to another and by swinging the lever 32 from one posithe ends of the arm rests tion to another the locking portions 36 are rotated to and from looking position.

The force exerted by the springs I8 is merely suflicient to elevate the back rest from horizontal to substantially vertical position and hence a slight pressure, suchas may be exerted either by the back of an occupant against the back rest or pressure applied to the arm rests i5, is sunficient to overcome the action of the springs l8. Hence, the occupant, while in a reclining position, may effect any desired adjustment of the back rest merely by applying slight pressure thereon or to the arm rests l5, and when the desired adjustment has been obtained, the occupant may then conveniently operate the lever 32 to lock the arm rests l5 which hold the back rest 3 in adjusted position.

While I have shown and described one desirable embodiment of the invention it is to be understood that this disclosure is for the purpose of illustration and that various changes and modifications may be made without departing from the spirit and scope of the invention as set forth in the appended claims.

I claim:
