/f LUTHER G. SIMJIAN ATTORNEY.

United States Patg 2,897,727 XZ AI .MO ING EAT I RQR "Luther iG.Simjian, Greenwich, 'Conn., nssignor to The t Reflectone-Corporation, Stamford, :(Zonm, a corporation of Connecticut 7 This invention relates to a chair construction of the type in which a rotating seat is adapted to rotate a mirror carried by the chair so that the person occupying the seat of the chair may adjust the mirror relatively to a stationary cooperating mirror. Chairs of the particular type are used by women to aid them in adjusting their hair and dress, as those skilled in the art will fully appreciate.

Much time and effort have been spent by inventors in this art, and I have conceived and developed a number of constructions embodied in chairs of the particular class and covered by United States patents. One problem that has long confronted the art and on which I have expended considerable time and effort is the centering of the chair seat by inexpensive uncomplicated means so as to effect the return of the rotating mirror to a centralized initial position when the person occupying the seat leaves the seat in a position other than that corresponding to a centralized position of the mirror. I have now conceived a solution to this problem that is extremely simple and effective, utilizing a minimum of parts, and as a matter of fact, requiring the addition of only a spring in order to contribute the required action. Thus, my new and novel concept involves the arrangement of a series of parts for effecting the movement of the mirror by the chair in such fashion that a single spring may be applied to maintain the seat in a particular position while allowing movement thereof from that particular position in either of opposed directions.

I have thus outlined rather broadly the more important features of my invention in order that the detailed description thereof that follows may be better understood, and in order that my contribution to the art may be better ,appreciated. There are, of course, additional features of my invention that will be described hereinafter and which will form the subject of the claim appended hereto. Those skilled in the art will appreciate that the conception on which my disclosure is based may readily be utilized as a basis for the designing of other structures for carrying out the several purposes of my invention. It is important, therefore, that the claim be regarded as including such equivalent constructions as do not depart from the spirit and scope of my invention, in order to prevent the appropriation of my invention by those skilled in the art.

Referring now to the drawings:

Fig. 1 is a perspective view of a chair in which my invention is installed.

Fig. 2 is a side elevation of a portion of my chair with parts thereof in section.

Fig. 3 is a plan view of the mechanism utilized in my invention, shown with the seat removed.

Fig. 4 is an enlarged elevation and section of parts shown in Fig. 2.

Referring now more particularly to the drawings, the seat of my chair is designated by the reference numeral and is secured by suitable screws or other means to a spider 11. Extending downwardly from this spider 11 is a pivot shaft 13 through which the spider 11 and the seat Patented Aug. 4, 1959 10 are rotatable-relatively to a base 1-2. 'The base 1 2- is best seen in -Figs.3 and 4,-and a-series of legs 20 for-supporting the base are shown in :phantomdash .anddotted llines in Fig. :3 The means whereby athe legs are secured to :the base are 40f .no importance \in' this application,v such uneansbeing shown iin-my othenpatents. V

The vbase 1-2 is formed, ;as;best seen in Figs. 3 and -4, ,with agenerally hiangularly shaped .opening 21 for the ;passage of,a.pin .14 extending downwardly fromthe spider .11 .to which the seatJOissecured. This .pin 14is an actuator .for .the .mirror :support .of my invention, v.this mirror support being also mounted for rotation on the base 12. Thus, the mirror support comprises a bracket 22 best seen in Fig. 2, this bracket being secured through a pair of bolts 23 and a part 30 to an arm 16 that is in the form of a rod. Arm 16, as best seen in Fig. 4, extends horizontally under the base 12 and is bent upwardly to form a bearing post at 24 relatively to the base 12, the base being bored at 25 for that purpose. Since the bracket 22 and the arm 16 must carry the back B of the chair as well as the mirror M, allas seen in Figs. 1 and 2, I arrange a portion 18 on the base 12 for reinforcing the bearing at 24, 25. Thus, the part 30 has secured thereto a strut 26 carrying a roller 17 that bears on the surface 18 of the base 12. This feature of reinforcing the mirror support is not part of this invention and need not be described in further detail in this appilcation.

The actuator for the mirror support, as earlier indicated, is the pin 14 extending downwardly from the spider 11 to which the seat 10 is secured. Pin 14 carries at its lower end a rotating yoke 15 that is in sliding relation to the rod 16 of the mirror support. Through this arrangement, when the seat 10 rotates on its shaft 13 relatively to the base 12, the pin 14 will, through yoke 15 rotate arm 16 on bearing 24, 25. I have so arranged the parts, that when the mirror is in its initial central position of Fig. 1, the actuator pin 14 lies in a line extending between hearing shaft 13 and bearing 24, 25 of the mirror support. Any movement of the pin 14 away from this line effects rotation of the mirror support including the back B and the mirror M.

Now, by placing a spring 19 in'position between the pin 14 and the bearings 24, 25, as is well illustrated in Fig. 4., I maintain the pin 14 yieldingly in the position of Figs. 3 and 4, which is the position corresponding to the back and mirror positions of Fig. 1. It will be noted that one end of the spring 19 is coiled about pin 14 and that the other end is coiled about post 24 of rod arm 16. Therefore, by a very simple arrangement of parts and by a very effective positioning of tension spring 19, I am able to hold the mirror and back yieldingly in the position in which I desire to have them. Further, as the seat 10 is rotated on its shaft 13 relatively to the base 12 in either of opposed directions from its position of Figs. 1 and 3, the spring 19 will be extended, and should the operator leave the seat 10, the seat will be immediately returned by the spring to its position of Figs. 1 and 3, returning the back and mirror also. I show in dotted lines in Fig. 3 just how the spring 19 is extended when the seat 10 is rotated in one direction, the two possible directions of rotation being well illustrated by the arrows in Figs. 1 and 3.

Those skilled in the art will now appreciate that through a simple and effective arrangement of parts, requiring merely the addition of a simple spring 19, I am able to obtain that result that has long eluded me and others in this art.

I now claim:

In a combination of the class described, a leg supported base, a seat, means mounting said seat in overlying relation to said base for rotation on a central axis relatively to said base, a mirror, a mirror support, means mounting mirror support in a line extending from said mirror support axis to said central axis when said seat is in an initial central position, means whereby said actuator rod rotates said mirror support as said seat rotates, and a coiled spring fixed at one end to said actuator rod and fixed at its other end to said base at the axis of rotation of said mirror support, whereby said spring lies with its axis in said line extending between said actuator and the axis of rotation of said mirror support when said seat is in said central position, whereby to resist rotation of said seat from said central position.
