SAFETY RING FOR A WINDOW BLIND
Abstract
A safety ring for a window blind has a ring and a connector. The
ring has a gap. The connector is connected to the ring and has
multiple tabs detachably mounted through and engaging the gap of
the ring. When a cord passing through the ring is pulled by lateral
force, the connector attached to a shade will disengage from the
ring. Therefore, the window blind is safely used and prevents
children from being wrapped in the cord.

Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a safety ring, and more
particularly to a safety ring for a window blind to prevent
children from choking hazards.
[0003] 2. Description of the Prior Arts
[0004] Window blinds are coverings for windows and serve the
purpose of adjusting or blocking the rays of light. To meet demands
for different users, various window blinds are produced and are
divided into two kinds a horizontal version and a vertical version.
The vertical version is pulled up and down including venetian
blinds, Roman shades, roller shades and the like.
[0005] With reference to FIG. 5, a conventional Roman shade has a
rail (40), a shade (41), multiple positioning rings (42) and
multiple cords (43). The shade (41) is fixed to the rail (40) at a
top edge and has a bottom. The positioning rings (42) are mounted
on the shade (41) at intervals and may be made of iron or plastic.
The cords (43) are mounted on the rail (40) and each cord (43) is
extended vertically and passes through corresponding positioning
rings (42) and is connected to a corresponding positioning ring
(42) near the bottom of the shade (41). By pulling or releasing the
cords (43), the shade (41) may be drawn or opened.
[0006] However, the cords (43) and the shade (41) are only fastened
to each other by the bottom-most positioning rings (42), so space
is formed between the cord (43) and the shade (41). Children easily
pull the cords (43) when they are at play and the cords (43) may
accidentally wrap around their necks causing a choking hazard.
Therefore, the conventional window blind is unsafe and is dangerous
for children.
[0007] To overcome the shortcomings, the present invention provides
a safety ring for a window blind to mitigate or obviate the
aforementioned problems.
SUMMARY OF THE INVENTION
[0008] The main object of the present invention is to provide a
safety ring for a window blind to protect children from choking
hazards for security.
[0009] A safety ring for a window blind in accordance with the
present invention comprises a ring and a connector. The ring has a
gap. The connector is connected to the ring and has multiple tabs
detachably mounted through and engaging the gap of the ring. When a
cord passing through the ring is pulled by lateral force, the
connector attached to a shade will disengage from the ring.
Therefore, the window blind is safely used and prevents children
from being wrapped in the cord.
[0010] Other objectives, advantages and novel features of the
invention will become more apparent from the following detailed
description when taken in conjunction with the accompanying
drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
[0011] FIG. 1 is a perspective view of a safety ring for a window
blind in accordance with the present invention;
[0012] FIG. 2 is an exploded perspective view of the safety ring
for a window blind in FIG. 1;
[0013] FIG. 3 is a side view in partial section of the safety ring
for a window blind in FIG. 1;
[0014] FIG. 4 is an operational perspective view of the safety ring
for a window blind in FIG. 1 with a shade; and
[0015] FIG. 5 is a perspective view of a conventional Roman shade
in accordance with the prior art.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0016] With reference to FIGS. 1 to 3, a safety ring for a window
blind in accordance with the present invention comprises a ring
(10) and a connector (20).
[0017] The ring (10) has a seat (11) and a gap (12) formed radially
through the seat (11).
[0018] The connector (20) is connected to the ring (10) and has a
body (21), multiple tabs (22) and a hook (23). The body (21) has
two sides. The tabs (22) are formed on and protrude from one side
of the body (21) and are detachably mounted through and selectively
engage the gap (12) of the ring (10). In a preferred embodiment,
two tabs (22) are formed on the body (21). The hook (23) is formed
on and protrudes from the other side of the body (21).
[0019] With reference to FIG. 4, the hook (23) of the connector
(20) is hung on a positioning ring (31) of a shade (30) and a cord
(32) is passed through the rings (10). By pulling or releasing the
cords (32), the shade (30) may be drawn or opened. The ring (10)
and the connector (20) stay connected up for normal force. Since
the hook (23) of the connector (20) is connected to the shade (30),
when the cord (32) is pulled laterally, the tabs (22) of the
connector (20) will disengage from the gap (12) of the ring (10) so
the cord (32) and the shade (30) are separated. Thus children
wrapped in the cord (32) easily escape. Besides, the hook (23) may
directly be hung on a strap (33) of the shade (30) without the
positioning ring (31).
[0020] Even though numerous characteristics and advantages of the
present invention have been set forth in the foregoing description,
together with details of the structure and features of the
invention, the disclosure is illustrative only. Changes may be made
in the details, especially in matters of shape, size, and
arrangement of parts within the principles of the invention to the
full extent indicated by the broad general meaning of the terms in
which the appended claims are expressed.
