Improvements in Adjustable and Convertible Infants' and
like Chairs.
I, FRITZ ULRICH of the firm of "Commandit-Gesellschaft Vereinigte Süge-
werke und Holzwaarenfabriken Haarmann" of Holzminden, Westphalia in the
Empire of Germany, Manufacturer, do hereby declare the nature of this invention
to be as follows:-
The object of this invention is an adjustable and convertible chair for infants and
similar use, the seat of which can be placed higher or lower, while the infant or
person is seated thereon, and which is constructed in the main as follows:
The seat is provided with a foot board and a vertical protective front side, while
to the arm-rests is attached in front a table so pivoted as to be adapted to be
turned up and down. To the bottom side of the table leaf are attached suitable
devices for imitating animal voices.
To the underside of the seat board the adjusting contrivance is secured which
consists of two vertical frames-one on each side-having at the top of their inside
a suitable number of notches or indents and being each connected with a lateral
protective board. In said notches are guided pivots, one of which is provided on
each top end of the respective two bars of the crosswise hinged chair supports, all
four of which are fitted at the bottom with rolls or castors.
It is obvious that by the arrangement described, the improved chair can be
adjusted while the infant is seated, and the seat placed so low that the whole forms
a kind of perambulator.
The improved adjustable chair may also have devices to allow its being
changed into a bed. For this purpose the adjusting frames are so arranged as to be
displaceable and an elongation of the seat is provided consisting of a piece of cloth
which is normally wound on a roller placed underneath the fore end of the seat and
so lodged with its pivots in longitudinal slots as to be displaceable therein by
means of an arrangement of shears suitably attached thereto and connected on the
other side to a spring placed underneath the rear end of the seat. Normally said
spring is strained and the shears are contracted, such position being ensured by a
suitably placed lever with catch. One of the cross stays between the hinged
supports of the chair is revoluble and provided with a cam, by the turning of which
the said catch lever can be released and the adjusting frames are raised sufficiently
to allow of free displacement of the support pivots therein. At the same time the
cloth roller, by the action of the released spring, is pushed forward by the shears,
whereby the cloth, secured with one end to the seat, is unrolled and forms the said
elongation. By turning the cam into its original position, the pivots of the
supports are brought into the notches of the adjusting frames and the whole can be
fixed in position. To change the bed chair again into a scat, the cam is given the
corresponding position and the adjusting frames are pushed in by hand, while the
cloth is wound up by a suitable spring provided on the roller and the catch lever is
fixed.

The improved chair Figs. 1 to 5 consists of the sent board A which is provided
with the foot board and the protective plate c To the arm rods a a is attached
the table leaf B which is revoluble about pivot i so as to be capable of being folded
up Fig. 5. Below the table Barrangements are provided for imitating animal voices.
The boxes C contain bellows & connected with cord pulls which terminate near the
pictures or ornaments representing the respective animals Fig. 4. Below the table
leaf A Fig. 1 the adjusting contrivance is arranged, which consists of parts J
provided with a slot and with noteles g and attached to lateral protecting boards 7.
In the slot pivots are guided which are secured to the top end of the forwardly
inclined supports H. The supports I have at the bottom rolls by means of
which the chair can be easily displaced in any position thereof, and are crosswise
connected with each other at & so as to be capable of being turned relatively to
each other.
By means of the adjusting parts.) the supports EL, that is to say the feet of the
chair, can be so adjusted in its height by aid of the notches g as to be converted
into a low carriage Fig. 5, without the necessity of taking the infant out of the
chair when the position of the sent is to be altered. The infant is always protected
from falling out by the table leaf 13 protecting plate c, foot board and adjusting
parts J.
To allow it to be converted into a hed, the improved chair is provided with
the following contrivance represented on Sheet 11 of the drawings. The adjusting
device Figs. 6 to 11 is so shaped that the parts can be displaced and that with
their displacement an underlayer or extension of table leaf A. is brought out.
Thereby a correspondingly long space for bedding the child is afforded.
The device for converting the seat into a bed consists of the following parts:
Below the seat A is provided in roller D, on which is rolled a piece of cloth o
destined to form the bed miderlayer. This roller is lodged with its pivots in
slots ee, in which it can be shifted to-and-fro by means of the shears S and spring F.
This shifting takes place mechanically as follows: The cluth o is normally rolled

page_text: on beam D, the spring stretched and the shears S folded in, Figs. 6 and 7 and this
position of the said parts is secured by the nose of lever m. One of the cross
rods connecting the supports H is revoluble and provided with eccentric L, so that
by turning the latter, the lever arm m can be pressed up and the nose r disengaged.
At the same time also the parts J for the guiding of the support pivots
lifted and allowed to freely slide in the slots without being influenced by the
notches g.
zare
The chair, in order to be converted into a bed by aid of the described mechanism
is given its lowest position Figs. 6 and 7. By turning the cross bar f the
eccentric L comes into action; the lever m is disengaged and simultaneously the
guiding parts J are held so high that the pivots z of the supports H can freely
move in the slots & Figs. 9 and 10. By the disengaging of lever m the spring F is
released, the shears S are stretched out Fig. 11, and the roller D is moved towards
the protecting plate c. Thereby the cloth o secured with one end to the sent
board A is rolled off and forms an underlayer. By turning the eccentric L into
its original position the pivots z are brought into the notches g 9, whereby the
whole device is fixed.
For converting the chair in the reverse way, the eccentric L is again given the
position shewn in Fig. 10 and subsequently the protecting plate part c and guiding
parts J are shifted in by hand, the cloth being rolled up again by a coiling-up
spring a connected with the roller Figs. and 11. Subsequently, by laying-in the
lever m, the whole device is given the original position Fig. 6.
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:
1.) An adjustable and convertible infants' chair, characterised by an arrangement
for placing the scat A high and low by means of supports H, which arrangements
consists of adjusting parts J, in the slots h of which notches g are provided in which
are guided and held pivots of the top side of the supports, a foot plate band
protecting plate c being attached to the adjusting parts J provided with lateral
protecting plates 4, while the cross bar i has attached thereto a folding table B
provided with a mechanism for producing animal voices, substantially as set forth.
2.) An arrangement forming a supplement to the infants' chair referred to in
Claim 1, for converting the chair into a bed, for which purpose the adjusting parts.
are made displaceable and provided with slot e, in which is displaceably lodged the
cloth roller D so connected with the shears S and spring F as to be displaced in
slote by releasing the lever m by means of eccentric L, while also the adjusting
parts are displaced, whereby the chair is clongated into a bed as shown by
Figs. 10 and 11, substantially as set forth.
