DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a roll blind S capable of preventing a safety accident caused by a screen height adjusting line according to the present invention will be described in detail with reference to the accompanying drawings and preferred embodiments.

First, a roll blind S capable of preventing a safety accident caused by a screen height adjusting line according to the present invention is constituted by a longitudinal frame 30 mounted and fixed to a ceiling or a wall as shown in FIG. The frame 30 may be fixed to a ceiling or a wall surface, or may be fixed to a mounting bracket (not shown).

Also, a support bracket (40) capable of supporting and holding the winding rods is formed in the left direction with respect to the frame (30).

4, the supporting bracket 40 is formed with a shaft groove 43 for performing a hinge function by inserting a fixing shaft 50 constituted by a bolt or an axial pin into a side surface thereof, And a latching groove 42 is formed on one side of the coupling piece 41 at the upper end where the falling damping member 80 can be engaged.

As shown in FIG. 4, the hinge shaft 60, which is engaged with the support bracket 40 and performs a hinge function, has a coupling hole 61 corresponding to the shaft groove 43 at one side thereof, And the other side of the hole 61 is configured to be coupled with the winding rod 70.

Thus, even if the winding rod 70 is separated from the holder 90, the winding rod is fixed to the support bracket 40 and is not separated, but is rotated about the fixed shaft 50 for a predetermined interval. At the same time, It is possible to prevent the safety accident by lowering the speed by the falling damping member 80 instead of the rapid descent.

The falling damping member 80 engaged with the engaging protrusion 103 of the cover through the upper end surface of the frame 30 in the state of being engaged with the engaging groove 42 may be engaged with any one of a string or an elastic string, And has a function of making it flexible or stretchable so that when the winding rod 70 falls downward, it performs a function of making a low speed drop rather than a rapid drop.

5 to 6 and 9, the housing 100 for the screen winding is detachably coupled to the side frame 30 on the other side of the support bracket 40, And at least two locking protrusions 92 are formed at the edge of the holding groove 91. The holding recess 91 is formed in the holding groove 91,

That is, when the first assembly is performed, the housing 100 is inserted and fixed to the holder 90 by pressure, and is separated when pressure is applied by the load. At this time, the fastening protrusion 92 and the fastening groove 105 of the housing 100 can maintain a firmly fixed state at normal times.

5, 8, and 11, the housing 100, which is detachably inserted and fixed to the holder 90, is inserted into the swinging rod 70 and simultaneously driven when the screen height adjusting rope 20 is operated And a winding unit (101) in which the driving gear (102) is installed.

A cover 104 integrally formed with the engaging projection 103 is coupled to the winding unit 101 to drive the winding rod on the other side of the driving gear 102. On the other hand, On both side surfaces of the winding unit (101) and the cover (104), a latching groove (105) corresponding to the latching protrusion (92) is formed.

As shown in FIG. 5, a through-hole 106 is formed on the cover 104 so that the drop damping member 80 can easily engage with the coupling protrusion 103.

6 to 7, it is possible to minimize the frictional force that can be transmitted to the falling damping member 80 at the moment when the lifting rod falls, and to prevent the worn at the right angle section The guide block 110 is constructed.

At this time, the guide block 110 includes a release preventing groove 111 for preventing the falling damping member 80 from being separated from the upper end of the frame, The binding groove 112 and the guide roller 113 are constituted.

The roll blind S, which can prevent a safety accident caused by the height control line of the present invention having the above-described features, can be applied as it is by simply replacing a simple part on an existing blind, Since it is not a replacement, if the user wants to create a new atmosphere, the exchange is easy at any time.

In particular, when a child hangs on the screen height adjusting rope 20, a portion of the winding rope, that is, the portion where the height adjusting rope 20 is formed, is gradually lowered to the lower side by a small load (about 10 kg or so) It is possible to prevent a safety accident that may occur.

Generally, infants who are curious about hanging on the screen height adjusting rope 20 are about 3 to 5 years old, and since the infant at this age is more than 10 kg, the pull rods can be easily separated.
