To @ZZ whom- Z may concern.'

Be it known that I, PETER E. KURNIGK, a citizen of the United States of America, residing at San Francisco, in the county of San Francisco and State of California, have invented new and useful Improvements in Couch Armchairs, of which the following is a specification.

The object of the invention is to provide a relatively simple and comparatively inexpensive chair which may be readily converted by occupant to adapt it for supporting the latter in reclining position or to perform the functions of a couch, and which may also be readily adapted to serve either as a rocking or standing chair or as a rolling chair; and with these objects in view, the invention consists in a construction and combination of parts, of which a preferred embodiment is shown in the accompanying drawings, wherein Figure 1, is a side view of the structure adapted for use as a rocking chair with the rollers shown in dotted lines in the positions which they assume to hold the chair in a sta- *tionary or standing position and with the back shown in dotted lines in its lowered or extended position.

Figure 2, is a plan view.

Figure 3, is a front view, partly in section.

Figure t, is a detail section on the plane indicated by the line 4 4 of Figure 1.

Figure 5, is a view o-f the lower portion of the chair showing the rollers extended to support the chair in position for rolling.

The chair seat 10 is preferably provided with side arms 11 supported by supports 12 and fitted to slide in the seat is a leg eXtension 13 which in the. construction illustrated is provided at its edges with grooves 111 for engaging guides 15 moving inwardly from the depending` side bars 16 of the seat. Depending from the seat are the legs 17 carrying the rockers 18 (if the chair is designed to be converted into a rocking chair) and back 19 being pivoted as at 2O between the rearwardly projecting end portions of the seat to adapt it to occupy the upright position indicated in full lines or t-he substantially horizontal position indicated in dotted lines in Figure 1. The back is connected by means of lexible runners 21 consisting of cables or the equivalent thereof with the leg extension 13, said runners extending through guide grooves 22 in the arm rests and the forward uprights 12 and around suitable friction pulleys 23 so that the rearward movement of the back causes the forward movement of the leg extension in position, and the tension of the springs 24 which connect the rear edge of said extension with the frame of the seat. Obviously the release of pressure upon the back will permit of the elevation of the latter and the retraction of the leg extension.v

In order to secure the movable elements consisting of the back and leg elements in their adjusted positions, a clamping means may be employed such as a cam 25 which may loe fulcrumed in the arm rest, to `bear upon the runner 21 extending therethrough7 said cam being provided with a handle 26 which is laterally yieldable and is provided with a terminal stud 27 for engagement with the socket 28 in the side of the arm rest to lock the handle in position when the cam is in position to lock the runner against movement. Obviously the runner may be freed by the occupant of the chair merely by flexing the handles to disengage the studs 27 from the sockets 28 and permitting the handles to withdraw the cams from their engagement with the runners. Y

Pivotally mounted upon the supporting frame of the seat as at the points 29 and 30 are supports 31 and 32 carrying rollers 33 and 34: adapted to be depressed into contact with the floor or other surface upon which the chair rests, for example, to support the latter in a Xed or standing position when it is desired toprevent oscillating movement upon the rockers 18; and also adapt it to be rolled to still other places when it is desired to move the chair.

To this end an operating lever 35 is fulcrumed as at 36 upon the chair structure and is connected at opposite sides of its fulcrumed points with the supports 31 and 32, said lever traversing a rack 37 to which it is secured in its adjusted position. A terminal grip 38 may be provided on the end of the lever within convenient reach of the occupant of the chair andrin the constructionV direction will cause ak corresponding ino-ve-V ment of the roller supports, or in other words will either elevate or depress theV said rollers to perniit of the supporting of the` chair upon its rockers or to secure it against roeking` movement but to leave, or so that Vthe oliair may be rolled by an attendant.

The invention having been described, What iselairned its new and useful is A convertible chair having a seat provided with depending,- legs and rockers carried at the lower ends of the legs, rear roller earrying supports pivoted to tlie rockers adjacent the rear ends, forward roller carrying supports pvoted adjacent the front legs, pivotally mounted operating levers disposed on A oppositeA sides of the chair, links connecting said levers with the forward roller supports, pin` and slot connections between the extremities of the levers and the rear supports,

ture.

PETER E. IURNICK.
