Improvements in or relating to Folding Chairs or Seats.
A communication from FRANZ OTTO BRANDT, of Maternistrasse 181, Dresden, A.,

"
I, ALFRED. JULIUS BOULT; of 111, Hatton Garden, in the County of Middlesex,
Chartered Patent Agent, do hereby declare, the,,nature of this invention and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:
The chair according to this invention is more comfortable than an ordinary camp-
stool, sketching stool etc., occupies much less space and is folded in a different manner
than iron garden seats which are made for fixed. use and are designed with a different
object in view. By making the side-rests or arms and the back hinged to the seat
and so that the side rests can be folded down on to the seat and the back on to the
side-rests, the seat according to this invention can be folded into a flat packet of
the size of the seat. The legs which are also made to fold may be arranged-
for instance as shown in the accompanying drawings-so that they are permanently
secured to the under side of the seat and need not be separately packed and
carried..
The article is here illustrated as a toy-chair for children, which may be
carried by two persons grasping the side-rests.
Figure 1 being a front elevation of the chair unfolded:
Figure 2 a vertical section on the line 2-2 of Figure 1:
Figure 3 a bottom view of the chair folded:
Figure 4 a front elevation of the same:
Figure 5 a side elevation of the same:
Figures 6 and 7 show separately the joint of the side-supports and back.
A is the seat, to the hinges of which are connected side-rests or arms B by.
means of hinges b. The hinges are arranged on the inner side of the arms B, so
that, when the latter are folded down the edges of the seat remain uncovered to
the extent equal to the thickness of the side rests (Figure 4). At the back edge
of the seat A is arranged a bar or ledge a corresponding to the thickness of the
side-rests, the back C being pivotted about said bar by means of hinges cc, the
projecting edges c¹ of of the back C lie, when the seat is folded, on the edges of
the seat left free by the side-rests B B and thus enclose the side rests (sec
Figure 4).
In this way the folded seat shown in Figures 4 and 5 is produced. A hook d
on the bar c cooperating with a pin don the seat, (Figures 3 and 5) holds the
seat together. In the front surface of each of the bars c' is inserted a small plate e
with a slot open towards the inner edge of the bar. With this slot engages, when
the side rests are unfolded, a headed piu el secured to the back edge of the side-
rests, whereby the hinges c of the back as well as the hinges b of the side-rests,
are relieved, since the heads of the pins el take up the back pressure on the back,
the ends of the slots limiting the outward movement of the pins (Figure 7).

page_text: The upper horizontal bars of the side-rests may be formed into handles. In
the drawing, however, separate handles F are provided, the branches f of which
provided at the bottom with heads or projections are vertically adjustable in
passages in the side-rests (Figure 2). When the chair is to be carried, the handles
are pulled out whilst when it is to be folded, they are pulled in. (Figure 2 'dotted).
A leather strap G provided with holes may be secured to pins g (Figures 3 and 5)
for greater convenience of carrying the folded chair. It may also be utilised in a
child's chair, when the chair is unfolded by securing it to pins gl of the side rests
(Figures 1 and 2) in order to prevent the child from falling out.
The legs may be of any desired construction. They are preferably permanently
attached to the under side of the seat and constructed as follows:-
A frame constituting by two pairs of cross rods H H connected together by a
rod H. The two rods H are movable on hinge joints h near the front lower
edge of the seat. The upper ends of the other two rods are connected together by
a rod h. This rod engaging with pivotted hooks 2 on the seat (Figure 2) when
the legs are unfolded, whereby they will be maintained in position. If the rod ¹
is removed from the hooks 2 h2, the legs H₁ can be turned about the rod H* in
the direction indicated by the arrow in Figure 2, until they lie in the same
plane with the legs H H, and the rod h¹ come into position adjacent to h h. Then
the legs, folded flat, can be turned about the hinges h h towards the under surface
of the seat (Fig. 3). When in this position, the hooks h³ are turned over the
legs H H whereby the legs are secured. In this construction no separate securing
device is necessary for the legs.
Having now particularly described and ascertained the nature of the said inven-
tion as communicated to me by my foreign correspondent, and in what manner the
same is to be performed, I declare that what I claim is :-
1. A folding seat, comprising side-rests hinged to the seat and a back pivotted
about a bar c of the seat, so that the side-rests can be folded down on to the seat
and the back onto the side-rests, in which position it covers the seat, the whole
forming a flat, easily carried seat, substantially as described.
2. A seat of the kind described having folding legs on the under surface of the
seat, comprising two pairs of crossed rods connected by a transverse rod, hinges
near the front edge of the seat for connecting two legs to the seat and pivotted
hooks for holding the legs in open and folded position, substantially as described.
3. A seat of the kind described having on the side-rests handles adapted to be
pulled out substantially as described.
4. A folding chair substantially as described or illustrated in the accompanying
drawings.
