The present invention relates to a roll blind, and more specifically, to improve the driving mechanism of the driving bracket in the existing roll blind, it is easy to disassemble and assemble the main components constituting it, as well as excellent assembly and construction, as well as the driving bracket The present invention relates to a drive mechanism of a drive bracket for roll blinds that is stably supported from and improved in stability of operation.

In general, blinds are used as a substitute for curtains and installed on windows provided on the outer walls and inner walls of various buildings, and are used as a means for controlling light blocking or indoor lighting and preventing invasion of privacy in the room. In addition, it is emerging as an important element of interior decoration that softens the hardness of glass and improves the aesthetic appearance according to the color combination. Such blinds are known as roll blinds or line blinds in the form of one or a plurality of shades in the horizontal direction, that is, the blinds are spread or rolled up, and vertical blinds in which a plurality of the blinds are arranged as ropes in the vertical direction. .

Figure 1 is a block diagram showing a disassembled drive mechanism of the drive bracket with the structure of a conventional roll blind is shown.

The normal blind 1 is provided with driving and driven brackets 3 and 4 on both sides of the fixing frame 2 fixed to a wall or the like, and a weight rod 8 is fixed between the brackets 3 and 4. The drum 5 in the form of a pipe in which the blinds 7 are wound along the outer circumferential surface thereof is rotatably installed. At this time, a drive mechanism 10 is installed in the drive bracket 3 to connect the ball chain 11 to rotate the drum 5 so that the blind 7 can be opened or wound, and the driven bracket 4 ) Is provided with a support mechanism (not shown) for guiding the blind (7) to lower itself by the weight of the weight bar (8) when the blind (7) is unfolded or wound using the ball chain (11) Consists of the configuration.

The conventional drive mechanism 10 includes a drive body 15 which is integrally coupled with a drive shaft 14 penetrating on the wheel 12 engaged with the ball chain 11 and supporting the spring 13 as shown in FIG. 1, It is composed of a cover 17 to be connected to the drum (5) is coupled to the engaging jaw (14a) of the drive shaft 14 while receiving the tip of the drive body (15). At this time, the driving body 15 is configured to be rotatable by mounting the seat plate (3a) of the drive bracket 3 through the through hole of the drive shaft (14).

By the way, such a drive mechanism 10 can not completely disassemble the drive body 15 when it is necessary to disassemble the main components constituting it to check or replace, that is, the drive body 15 is As shown in FIG. 1, since the ball chain 11, the wheel 12, the spring 13, and the driving shaft 14 are integrally formed, disassembly is not easy and very cumbersome, and reassembly after disassembly is relatively difficult, so that assembly and workability There is a disadvantage of deterioration.

In addition, as the drive body 15 is rotated while being simply seated on the seating piece 3a of the drive bracket 3, the drive bracket 3 and the drive body 15 cannot be held in a stable coupling state. There is a disadvantage that the bondability is extremely degraded.

Accordingly, the present invention is to fundamentally solve the conventional problems as described above, by further improving the driving mechanism of the driving bracket in the existing roll blind, and easy to disassemble and assemble the major components constituting it, excellent assembly and construction properties In addition, to provide a drive mechanism of the drive bracket for the roll blind that is stably supported from the drive bracket to improve the operation stability of the purpose is to.

In order to achieve this object, the present invention provides a drive mechanism installed between a drum and a driving bracket of a roll blind to raise and lower the blind: a protrusion 31 and a binding groove 32 and a penetrating portion through which one surface protrudes. A driving bracket (30) having a ball (33) and engaged with the connector (35) on which the spring (36) is supported by the fixing protrusion (31) and the binding groove (32); A driving wheel 40 seated on an outer circumferential surface of the connector 35 and having a ball chain 42 engaged with a wheel 41 having a driving piece 41a in contact with a spring 35; The operating piece 51 is provided at one end in contact with the driving piece 41a of the driving wheel 40, and the other end is provided with an operating stone piece 52 engaged with the mounting hole 55 connected to the drum 5 at the other end.
