Improvements in Folding Doors.
I, HUGO BECKER, Upholsterer and Decorator, of 12, Brigbong, Neumunster,
i/H, Germany, 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 object of the present invention is a folding door, the distinguishing feature
of which is that it is composed of a number of independent staves or of staves
suitably joined together and on which the material serving for covering the door
(such as cloth, felt, leather or the like) is fastened, so that for the purpose of
economising space the said staves can be folded together so as to occupy no more
space than their own thickness, any intermediate space being thus avoided. In
order to ensure the due working of the contrivance it will naturally be found
suitable to connect the separate staves by means of joints after the fashion of the
Nuremberg shears (or scissors) such joints, when the staves are put together lying
in recesses in the same. As in most cases joints of the kind are provided at dif-
ferent heights, these shear or scissor joints can be connected by means of a rod,
which keeps them in a longitudinal direction.
In the accompanying drawings, Fig. 1, represents a door of the kind in front
view with the cloth removed. Fig. 2, a portion of the side view on a larger scale.
Fig. 3, shows a plan of the door corresponding with Fig. 1, and Fig. 4, the plan
of the same in a folded condition.
The door consists, as stated above, of separate staves a, on which the material b
for covering the door, is fastened. The material may be cloth, plush, leather, or
any other suitable stuff. If the staves be drawn out, so that the whole form a
door, they assume the position shown in Figs. 1 and 3; if pushed together, on the
contrary, they assume that shown in Fig. 4, in which the strips of material
between the separate staves (see Fig. 3) are drawn together.
The movement of the separate staves is secured in a suitable manner, and this
is best effected by means of joints g after the fashion of the Nuremberg shears
(or scissors), which, when the staves a are pushed together lie in recesses f of the
same.
In order, in case guide joints of the kind are provided at different heights, that
it may be possible to connect the same, two joint pieces of the first layer of staves gl
for example can be lengthened (as can be seen in Fig. 1) and then connected
together by a rod h running in the longitudinal direction of the staves. This
rod h will then be guided in the longitudinal direction, for which purpose the
guide shown in Fig. 2, would perhaps be most suitable. As a matter of course,
any other guide could be equally well employed.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be employed, I declare that what I
claim is :-
1. Folding door, characterised by a number of staves a independent of one
another. or suitably connected together, on which the material 6 for covering the

page_text: door (cloth, felt, leather or the like) is fastened, so that the same for the purpose
of economising space can be folded down to their own thickness, any intermediate
space being avoided.
2. A form of the contrivance claimed under Claim 1, in which the separate
staves a are connected together by joints g after the fashion of the Nuremberg
shears (or scissors) which, when the staves are laid together, lie in recesses f
of the same.
3. In a contrivance as claimed under Claims 1 and 2, the connecting of the
shear (or scissor) joints 9, furnished at different heights by means of a rod h,
guided in the longitudinal direction of the staves a.
