SAFETY RETAINER FOR USE IN CURTAIN CONTROLLING ROPES

DISPOSITIF DE RETENUE SECURITAIRE POUR UTILISATION DANS DES CORDONS DE COMMANDE DE RIDEAU

English Abstract

A safety retainer for use in curtain controlling ropes comprises first and second housings which engage with each other, wherein the first and second housings include four holes formed on the tops thereof, and two of the holes are formed by combining two semicircle-shaped holes together, between the first and second housings are respectively disposed protrusions and recesses corresponding to each other, on the combined bottom surface of the first and second housings is arranged a bore, such that the two or more controlling ropes are individually inserted into the holes and extended out of the bore for being limited, and a groove is annularly formed on the combined side periphery of the first and second housings for receiving a loop, thereby allowing the controlling ropes to be retained in the groove by the loop, and causing the first and second housings disengagement from each other because an external weight concentrate onto the safety retainer.

French Abstract

Un dispositif de sécurité pour utilisation dans des cordons de commande de rideau comprend un premier et un deuxième boîtiers qui viennent en prise l'un avec l'autre et qui comprennent quatre trous formés sur les sommets de ceux-ci, deux desquels sont formés par combinaison de deux trous en forme de demi-cercle, entre les premier et deuxième boîtiers respectivement qui sont pourvus de bosses et de creux correspondant à l'autre; on trouve sur la surface inférieure combinée des premier et deuxième boîtiers un alésage, de sorte que les deux ou plusieurs cordons de commande soient insérés individuellement dans les trous et s'étendent hors de l'alésage pour être limités, et une rainure est formée de manière annulaire sur la périphérie latérale combinée des premier et deuxième boîtiers pour recevoir une boucle, permettant ainsi la commande des cordons à être retenus dans la rainure par la boucle, et amener les premier et deuxième boîtiers à se désengager à cause d'un concentré de poids externe sur le dispositif de retenue sécuritaire.

SAFETY RETAINER FOR USE IN CURTAIN CONTROLLING ROPES
BACKGROUND OF THE INVENTION
Field of the Invention
The present invention relates to a retainer, and more particularly to a safety
retainer for use in curtain controlling ropes that can prevent an accident
happening to
child due to the controlling ropes wrap around his neck.
Description of the Prior Arts
Generally, curtain is applied to shade the sun. In order to enhance the
operational convenience for curtain, a plurality of controlling ropes are
attached to
the curtain so than the user can manually control the sun shade area of the
curtain by
pulling the controlling ropes, hence the controlling ropes are indispensable
compartments for the curtain.
Although a retainer is always secured onto the plurality of controlling ropes
for retaining the controlling ropes, and for preventing the controlling ropes
from
knotting, the bottom sections of the controlling ropes respectively form
rounded
ropes, hence if child's neck is accidentally wrapped by one of the round
ropes,
asphyxiation probably occurs.
The present invention has arisen to mitigate and/or obviate the
afore-described disadvantages.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a safety retainer
for use in curtain controlling ropes, which can allow controlling ropes to be
retained
in a groove by a loop thereof, and if child's neck is wrapped by the
controlling ropes,
I

CA 02591178 2007-06-08
his weight is forced onto the safety retainer by the controlling ropes which
are
retained in the safety retainer, hence two separated forces cause first and
second
housings to disengage from each other, and the loop disengages from the
groove,
then the controlling ropes remove from a bore separately, thus releasing the
wrapped
controlling ropes from the child's neck.
The safety retainer for use in curtain controlling ropes includes a first
housing and a second housing which engage with each other for retaining two or
more controlling ropes, wherein the first and second housings include four
holes
formed on the tops thereof, and two of the holes are formed by combining two
semicircle-shaped holes as a whole, between the first and second housings are
respectively disposed protrusions and recesses corresponding to each other, on
the
combined bottom surface of the first and second housings is arranged a bore,
such
that the two or more controlling ropes are individually inserted into the
holes and
further extended out of the bore for being limited therein, and a groove is
annularly
fDrmed on the combined side periphery of the first and second housings for
receiving
a loop, thereby allowing the controlling ropes to be retained in the groove of
the
safety retainer by way of the loop, and if a sudden weight is forced onto the
safety
retainer by the controlling ropes, two separated forces form to cause the
disengagement of the first and second housings from each other.
The present invention will become more obvious from the following
description when taken in connection with the accompanying drawings, which
show,
for purpose of illustrations only, the preferred embodiment in accordance with
the
present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
A safety retainer 10 for use in curtain controlling ropes in accordance with
the present invention comprises a first housing 1 and a second housing 2 which
engage with each other for retaining two or more controlling ropes 201, as
shown in
FIG. 1, wherein the first and second housings 1 and 2 include four holes 11
and 21
3

CA 02591178 2007-06-08
formed on the tops thereof, as shown in FIG. 2, and two of the holes 11 and 21
are
formed by combining two semicircle-shaped holes as a whole, between the first
and
second housings 1 and 2 are respectively disposed protrusions 12, 22 and
recesses 13,
23 corresponding to each other, on the combined bottom surface of the first
and
second housings 1 and 2 is arranged a bore 3, and a groove 31 is annularly
formed
on the combined side periphery of the first and second housings I and 2 for
receiving a loop 4 as illustrated in FIG. 3, such that the two or more
controlling ropes
201 are individually inserted into the holes 11 and 21 of the first and second
housings 1 and 2, for example, two controlling ropes 201 are inserted into the
holes
11 and 21 respectively, yet while three controlling ropes 201 inserted, the
third
controlling rope 201 is inserted into either of the combined holes 11 and 21
so that as
any two controlling ropes 201 are pulled apart from each other, the safety
retainer 10
can be disassembled into the first and second housings 1 and 2. Besides, the
controlling ropes 201 are further extended out of the bore 3 for being limited
therein,
thereby allowing to be retained in the groove 31 of the safety retainer 10 by
way of a
loop 4.
While in operation, the first and second housings 1 and 2 of the safety
retainer 10 are not easily disengaged, thereby securely combing them together
and
retaining the plurality of controlling ropes 201 by means of the loop 4.
However, if
child's neck is wrapped by the controlling ropes 201, his weight is forced
onto the
safety retainer 10 by the controlling ropes 201 which are retained in the
safety
retainer 10, hence two separated forces cause the disengagement of the first
and
second housings 1 and 2 from each other as illustrated in FIG. 5, and the loop
4
4

CA 02591178 2007-06-08
disengages from the groove 31, then the controlling ropes 201 remove from the
bore
3 separately, thus releasing the wrapped controlling ropes 201 from child's
neck.
The loop 4 may be a resilient loop or a C-shaped fastener as shown in FIG.
6, and the recess 31 of the safety retainer 10 may also be arranged in a multi-
recesses
manner for receiving a plurality of corresponding loops 4 respectively, thus
enhancing the engagement of the safety retainer 10 as illustrated in FIG. 7.
After inserting into the holes I1 and 21, the controlling ropes 201 may be
individually knotted thereon for retaining as shown in FIG 8, and a main rope
5 with
a knot thereon extends out of the bore 3 so that the user can operate the
controlling
ropes 201 by pulling the main rope 5.
The invention is not limited to the above embodiment but various
modifications thereof may be made. It will be understood by those skilled in
the art
that various changes in form and detail may made without departing from the
scope
and spirit of the present invention.
