Description

A bracket of roll-screen}

The present invention relates to a driven bracket of a roll screen, and more particularly, to form a reinforcement support for reinforcement of a bearing groove in a driven bracket for bearing a driven side of the roll screen to improve the shaft support rigidity and to protrude the reinforcement. It is an object of the present invention to make the coupling of the take-up roll easy and quick by forming a flow inclined surface and a coupling guide wall for inducing the coupling of the keeper pin coupled to the keeper groove of the branch.

In general, the roll screen is used to block dimming through a window or the like by winding or recommending a screen made of fabric or synthetic resin by a user's operation, the configuration of the screen 210 made of fabric or synthetic resin, and the screen 210 ) A winding roll 220 provided to be able to wind or recommend the roll, a roll driving unit 230 provided at one side of the winding roll 220 to rotate the winding roll 220, and the roll driving unit ( An operating chain 240 for applying a rotational force to a user's operating force on the 230, a driving bracket 250 for bearing one side of the winding roll 220 provided with the roll driving unit 230, and the roll driving unit 230 The upper end of the driven bracket 260 and the driving bracket 250 and the driven bracket 260, which hold the other side of the winding roll 220 is not provided with each other and can be fixed to a fixed position such as a wall surface With fixing bar (270) It will be sex.

In the conventional roll screen configured as described above, when the user pulls the operation chain 240 in one direction, the roll driving unit 230 is rotated by the operation chain 240 so that the take-up roll 220 is rotated so that the screen 210 is rotated. This will be developed or wound up.

On the other hand, the conventional roll screen as described above is configured to elastically project the axial pin 222 of the axial part 221 provided on both sides for easy detachment of the take-up roll 220, the axial pin 222 is the elastic protrusion In order to increase the rigidity of the driven bracket 260 supporting the support bracket 260 to form a protrusion on the surface of the driven bracket 260 facing the bearing portion 221 in a circular shape and the bearing groove 261 is formed in the center of the protrusion The bearing portion 221 of the take-up roll 220 also corresponds to and forms a bearing groove 261 recessed in a circular shape.

However, as described above, the protrusion and the bearing groove formed to increase the support rigidity of the driven bracket 260 bearing groove 261 made of a plate form a surface contact to increase the frictional force to rotate the roll driving part 230 and the same. There was a problem such as shortening the life of the chain 240.

In addition, there is a problem that the surface-contacting protrusion and the bearing groove cause noise by friction.

In addition, in fitting the jersey pins 222 of the jersey portion 221 in the center of the circular protrusions, there are many problems in the coupling phase such that the induction of the coupling does not occur smoothly and is missed.

Thus, the present invention prevents the reduction of the life and noise generation of the roll drive unit and the operation chain due to friction of the driven bracket and the shaft portion as described above, so that the coupling pin is inductively coupled in the coupling process of the take-up roll. It is to facilitate.

That is, the present invention is formed by protruding the reinforcing support portion tubularly to improve the support rigidity of the driven bracket axial grooves for axial axis pins, axial grooves from the bracket body to guide the coupling of the axial pins into the protruding axial grooves The inclined guide portion is formed to be inclined in one direction of the vertical direction and the horizontal direction, the coupling guide wall is formed on both sides of the inclined guide portion.

Accordingly, the present invention is to project the tubular reinforcement support in the shaft groove of the driven bracket to improve the support rigidity and to form the guide inclined portion and the coupling guide wall in the bonding process of the take-up roll is guided by the bearing pin, It is done easily and smoothly.
