COMPLETE SPECIFICATION.
An Improved Guide and Holdfast for Roller Blind Cords and
the like.
I, GEORGE GEISSELBRECHT, of Furth, Bavaria in the Empire of Germany,
Watch Maker, 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 this invention is to provide a simple guide and holdfast adapted to
guide the cord of a roller window blind or the like and to secure it when released.
It consists essentially of a wire hook which in its larger part forms the guiding for
the cord whilst it operates as holdfast in the narrower part formed by its two parts
closing narrowly together. This hook is placed close under the cord roller of the
window blind and is soldered on the bearing hook of the trunnion of the said roller.
In the annexed drawing Fig. 1 shows the construction in combination with a
roller window blind in perspective front view Fig. 2 in side view. Figs. 3 and 4
show the apparatus alone in plan view and side view.
The bar a of the roller window blind with the cord roller is carried by the
trunnion upon the bearing hook d screwed into the frame of the window or
otherwise fastened, this hook d is of any known construction. The hook formed
for the guiding and the retaining of the cord consists as shown in Figs. 1 and 3 of a
wire e which at one end f is wound round the bearing hook d and solidly soldered
The other end is bent to form a round hook g, the end of which approaches
and lies at h against the wire e. In this manner a hook is produced which at one
end is round and at the other end narrows as shown; it will lie under the cord
roller b by means of a corresponding bending of the wire e at el.
on.
The action of this device is as follows: When the rolling blind is to be rolled up
the cord is pulled towards the interior of the room so that it leaves the retaining
legs hand e and enters the round guiding hook g. When the cord is released it
falls back into these retaining legs is drawn into and gripped by them and prevents
immediately the running down of the blind. The loosening of the holdfast is
effected by pulling the cord i towards the interior of the room as in the direction
of the arrow in Fig. 2 when it may be allowed to run through the hand. It will
be seen that by means of this device if the cord is suddenly released the blind
will not fall since as soon as the cord hangs vertically it is gripped spontaneously
by the hook.
Having now particularly described and ascertained the nature of this said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :--
A. device for guiding and spontaneously arresting cords of roller window blinds
and the like consisting of a wire hook fastened upon the bearing hook d and
advancing under the cord roller & the said hook having a larger part g as guide and
closely lying legs h and e as holdfast for the cord i substantially as set forth.
