1,568,244 w. ROSENKRANZ FOLDING CHAIR Filed March 18, 1925 INVENTDR Patented Jan. 5, 1926.
W'ILHELM ROSENKRANZ, OF HOLZMINDEN-ONTHE-WESER, GERMANY.
FOLDING CHAIR.
Application filed March 18, 1925.
To all whom it may concern:
Be it known that I, VVILHELM Rosan- KRANZ, a citizen of the German Republic, residing at Holzminden-on-the-lVeser, Germany, have invented certain new and useful Improvements in Folding Chairs, of which the following is a specification.
This invention relates to a folding chair of the kind in which the seat is suspended from the principal frame by means of crank pins which cause it to fold outside the plane of the frame and produce a flat and compact structure.
The object of the present invention is to produce hinging means of a very simple nature and which can easily be applied, and the invention consists in the provision of an S-shaped hinge element, one end member of which is connected to the frame and the other to the seat, while the intermediate member is recessed into the edge of the seat so as to form a rigid connection with the latter.
Fig. 1 of the accompanying drawings represents a vertical section of the chair in position of use, and t Fig. 2, a similar view of the chair in folded position.
Fig. 3 is a View showing the hinging of the seat to the chair frame, and
Fig. 4, a top View of the corner of the seat to which the hinge-pin is connected.
5 is a. side view showing a modification of the hinge-pin, and
Fig. 6, a bottom view of the same.
The chair is composed of a principal frame (0 o the upper part of which forms the back rest and carries for this purpose the necessary lattice work a. The lower part of the frame members a constitute the front legs of the chair. A minor frame d which constitutes the rear legs of the chair, is carried across the principal frame so as to support the front part of the seat 6 to which it is hinged at 0, the seat being itself hinged to the principal frame. The frame at is supported on pins a which ar Serial No. 16,539.
connected to the frame members a and which engage longitudinal grooves d in the frame members d so as to allow the necessary slidable as well as pivotal relative adjustment for folding and unfolding the chair. A brace (Z connects the lower ends of the frame members (Z.
The seat Z) is, in known manner, hinged to the frame members a so as to be displaced out of the plane of the latter when it is folded, as shown in Fig. 2. This arrangement allows the seat to clear the back rest so that it can be folded flat against the latter and easily fastened to the frame members. The fastening of the folded seat to the back rest may be elfect-ed by means of hasps g which are connected to the frame members a and which hook into staples h 05 connected to the edge of the seat.
The hinge elements 6 whereby the seat is connected to the frame members a are, according to the invention, S-shaped and one end member of each is in pivotal enside of the seat, as shown in Figs. 5 and 6.
The upper cross-bar of the principal frame is slotted at f to form a convenient handle for the manipulation of the chair.
I claim:
In a folding chair of the character de- 35 scribed, the combination with a main frame and a seat, of S-shaped hinge elements having one end member connected to the seat and the other to the frame, the seat being recessed to accommodate the intermediate member of the hinge element so as to prevent rotary displacement of the latter relative to the seat.
