Improved Folding Chair.
I, HEINRICH LUDWIG CARL FRIEDRICH IHDE, of 19, Henrietten Strasse,
Hamburg-Eims-Büttel, Germany, Woodwork Manufacturer, 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 state-
ment:-
This invention relates to an improved folding chair which is so adapted that,
without necessitating the use of springs or the like and merely by gravitation,
it will automatically and readily fold or close up when lifted by its back part,
and when set down again will assume the position required for its being used,
and by reason of the simplicity and consequent cheapness of its construction will
be particularly adapted for manufacture on a large scale and can readily be
made to suit the weight of any user.
The construction of the chair is illustrated on the accompanying drawings,
in which
Fig. 1, is a sectional elevation showing the chair opened in position ready
for use;
Fig. 2, is a similar view to that of Fig. 1, showing the chair in its nearly
closed or folded position; and
Fig. 3, is a front elevation of the chair as seen in Fig. 1.
As will be seen on the drawings, the chair consists substantially of a frame, b,
connected with the back, a, and a frame, c. These two frames, b, and c, form
the legs of the chair and are connected by a spindle, d, which is excentrically
fitted, so that, when the frame part, a, b, is lifted, the frame, c, automatically
folds downward and against it (ride Fig. 2).
The seat, e, of the chair is pro-
vided, at its under part, with two flat bars, f, preferably made of iron, the ends
of which are bent to the form of semicircles and hold the seat to the frame
parts, c, and b, by clasping on the cross bars, c', 6', and do so the more tightly
the greater the weight placed thereon. Beside these flat bars stay-ribs, 9, are
provided. A round bar, i, bent to a U-shape is secured to the under part of the
seat by means of eyelets, h, applied to the stay-ribs, g, and is also capable of
rotation about the spindle, d. A rod, m, strengthens the frame, b, and also serves
for the U-shaped bar, i, to bear against. A chain, 7, fixed to the cross-piece, k,
of the seat, e, and to the cross bar, c¹, of the frame, c, forms a loose connection
between the seat and the frame, c, and serves to regulate the fall of the seat.
The operation of the chair is as follows: When the chair is in position ready
for use the bent ends of the flat bars, f, engage with the crossbars, cl, and bi,
of the frames, c, and b, and so support the seat, whilst the U-shaped bar, i,
transmits weight to the spindle, d, and to the chair-legs.
-
If the chair is taken hold of by the back, a, and lifted up, the bars, f, dis-
engage from the cross-piece, 61, and the seat, e, therefore falls back and is borne
by the U-shaped bar, i, and is thus prevented from falling off entirely, and it
will, consequently, fold against the frame. In this position the chair will

page_text: occupy but little space and can thus be easily stored, and is made ready for use
again by simply setting it upon its legs, c.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is;
-
1. A folding chair having frames, b, and c, which form the legs and which
are connected by a spindle placed excentrically thereof and allowing rotation
of the same, as set forth.
2. A folding chair such as referred to in Claim, 1, the seat, e, of said chair
being connected in a movable manner with a spindle, d, by a U-shaped bar, i,
and with the frame, c, by a chain, 1, so that the weight is transmitted and the seat
is prevented from dropping, as set forth.
3. A chair such as referred to in Claims, 1, and 2, the seat, e, of said chair being
strengthened and supported by flat bars, f, the bent ends of which clasp on
cross bars, 61, and c¹, of the frames, b, and c, as set forth.
