Improved Mechanism for Holding Cords of Window Blinds and
the like.
I, GEORG WALTER, of No. 9 Wartenburg Strasse, Berlin, German Empire,
Cabinet 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 present invention relates to an adjusting and holding mechanism for cords or
straps of revolving shutters blinds and the like.
The invention consists essentially in causing the cord or strap to be pressed by
means of a swinging lever pivotted on a housing through which the same is passed,
so that it is held firmly by friction and secured in its position by means of a spring,
which engages in a slot of the pressing lever, so that an unintentional release of the
cord cannot take place.
Referring to the accompanying drawings:-
Figure 1 shows a front view of the cord holder.
Figure 2 shows a vertical section which illustrates the arrangement when
in use.
Figure 3 shows a vertical section in the disengaged position.
Towards the top of the piece A which is U-formed in horizontal section and is
fixed to the side of the window or the like, there is attached a lever B by means
of the bolt b. On this lever B is secured a piece of wood or the like C
possessing the cavity c. Opposite this said cavity there is secured to the base
plate A a bolt D the centre of which is as far removed from that of the bolt bas
is the centre of the cavity c. The strap or cord E slips over D and is guided
When the lever B
below by means of a roller H running loosely upon the bolt h.
is pressed against the cord E the cavity c will press the same against the bolt D so
that in consequence of the double bending of the cord considerable friction is
created between it and the adjacent parts and the cord is consequently held fast in
the position shewn in Figure 2. This position is assured by means of the spring F
which engages in the slot b¹ of the lever B, so that the edge f prevents an
unintentional release of the connection. If the spring F be pressed down a little
and the lever B a little raised the cord E will be released.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:-
A retaining device for blind cords and the like characterised by the com-
bination of a lever secured to a housing through which the cord passes and
having its axis of revolution parallel to the surface of the cord and being
suspended in front of the same, which lever possesses a projection with cavity
in front of the cord whilst the housing has a projection behind the cord, with a
spring catch attached to the housing which engages in a slot of the lever for

as described.
