ROCKING CHAIR Filed Dec. 15, i932 ROCKING r Yrjii Daniel Lampila and Ahti Ilrnari Lampila, Helsingfors, Finland Application December 15, 1932, Serial No. M7344:

In Finland March 16, 1932 2 Claims.

This invention relates to a rocking chair that is light, takes little room and is practical in that respect that it does not damage the floor and further it is absolutely noiseless. 5 The accompanying drawing illustrates by way of example an embodiment of the invention.

rfi'ig. 1 is a perspective view of the rocking chair, w e

Fig. 2 is a side view of the same.

The rocking chair illustrated in the drawing consists of a lower frame 2 placed on'the floor to support the chair and an upper frame 8 car'- rying the seat 3, the upper frame being at the point 6 pivotally connected with the lower frame.

' To the back of the seat one end of a suitably bent spring 1 is pivotally attached at the point '4, the other end of this spring being at the point 5 also pivotally attached to the lower frame 2. Several I such springs may be provided and'similar springs may also be arranged between the front of the seat and the lower frame. Instead of the plate spring shown in the drawing it is advantageous to use a spring composed of several wire springs placed side by side and held together by a sleeve y 26 9, 10. Such a spring has the advantage of being 35 same in such manner that on rocking the chair backwards these stop. and bearing elements contact with the lower frame thus preventing upsetting of the chair. 1

' The upper frame and the lower frame may be made of metal tubes, wood or any other suitable material while the seat is preferably madeof plywood, cloth or any other suitable material.

The above described rocking chair has only been given by way of example and may be modi- 5 fled in various manners without deviating from the scope of the invention.

"stop and bearing elements on the lower sides of said U-shaped portions, means pivotally connect- 20 ing said stop and bearing elements to the upper side of said lower frame, and a. bent spring pivotally connected at its upper end to therear side of the seat frame and at its lower end to the rear side of the lower frame and forming a reentrant angle directed toward the rear lower portion of the upper frame.
