An Improved Folding Chair.
I, CARL LAGERQUIST, of 61, Blumenstrasse, Berlin, in the Empire of Germany,
Furniture Manufacturer, do hereby declare the nature of this invention to be
as follows:
Folding chairs, which consist of two frames moving in a scissor like manner
with an apron of fabric fixed on the end rails of the same, have supporting devices,
which may become more or less dangerous to the person sitting on the chair, when
these supporting devices slide in consequence of a shock. These supporting
devices are attached some to the upper part of the scissor like moving legs and
are supported in the under part, some also attached to the under part and sup-
ported in the upper part by fastening devices. Such chairs are indeed very light,
but not stable enough.
{
The present invention is intended to produce an equally light, and folding, but
stable chair.
The seat and the seat back, which may be made with cane plaiting, reed
plaiting, cushioning, or the like, are connected with one another by means of
hinge joints. With the seat the two side supports forming the back legs are
connected by means of the hinge joints. The side supports forming the front
legs of the chair, are pivoted to the former side supports by means of bolts, and
also at their upper ends to the fixed back.
To the upper part of the front legs are pivoted arm-supports by means of
bolts, the latter arm supports are held up by means of other supports, which are
pivoted to the arm supports by bolts, and with the chair seat also by bolts. The
front legs are connected with one another by cross bars, and it will be preferable
also to connect the back legs by a cross bar.
In order to fix the chair in the upright position there is provided near the lower
ends of the back legs a well braced supporting frame, which engages under hooks,
which are arranged on the fixed back of the chair. By the frame reaching under
these hooks arranged higher or lower on the back of the chair, the angular
inclination of the chair can be changed, and it may be remarked, that only the
chair back obtains a more or less inclined position, whilst the chair seat keeps
approximately always the same inclination to the horizon.

page_text: what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement:
_
Folding chairs, which consist of two frames moving in a scissors like manner
with an apron of fabric fixed on the end rails of the same, have supporting devices,
which may become more or less dangerous to the person sitting on the chair, when
these supporting devices slip in consequence of a shock. These supporting
devices are attached some to the upper part of the scissors like moving legs and
are supported in the under part, some also are attached to the underpart and sup-
ported in the upper part by fastening devices. Such chairs are indeed very light,
but not stable enough.
The present invention is intended to produce an equally light, and folding, but
stable chair.
The annexed drawing shows a form of construction of such a chair. Fig. 1
shows a side view of the chair in the open position. Fig. 2 is a plan view of
Fig. 1. Fig. 3 shows the chair when folded together.
The seat a and the seat back b which may be made with cane plaiting, reed
plaiting cushioning or the like, are connected with one another by means of
hinge joints c. With the seat a the two side supports d forming the back legs
are connected by means of the hinge joints e. The side supports f forming the
front legs of the chair, are pivoted to the former side supports d by means of
bolts g and also at their upper ends to the fixed back b.
To the upper part of the front legs f are pivoted arm supports h by means of
bolts ; the latter arm supports are held up by means of other supports k, which
are pivoted to the arm supports h by bolts and with the chair seat a also by
bolts m.
The front legs f are connected with one another by cross bars n and it
will be preferable also to connect the back legs d by a cross bar.
In order to fix the chair in the upright position, there is provided near the
lower ends of the back legs d a well braced supporting frame p, which has its
turning point in o and engages under hooks g, which are arranged on the back
of the chair. By means of the frame p engaging under these hooks q which are
arranged higher or lower on the back of the chair, the angular inclination of
the chair can be changed and it may be remarked that only the chair back
is given a more or less inclined position thereby whilst the chair seat a keeps
approximatively always the same inclination to the horizon.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is:-
An improved folding chair substantially as illustrated having a seat a, a
back 6 hinged thereto and an arm supporting device h k articulated at i l m
in combination with a supporting frame p which is connected to the lower part
of the back legs d of two scissors like movable leg pairs d d and f f said sup-
porting frame p giving to the chair a secured stability by engaging under
hooks 9 arranged on the back 6 of the chair and avoiding the folding together
provoked by pushing on the support device.
