Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention relates to a blind mechanism for opening and closing an optical path having a lifting rope 21 for lifting and lowering movements of the plurality of light shielding wings 11 and 12 and an inclined rope 41 for tilting. The plurality of light blocking wings 11 and 12 is supported by a lifting code (not shown) in the downward direction of the housing 10, and performs a lifting and lowering motion by pulling forward and backward of the lifting rope 21. The lifting driver 20 engaged with the upper side of the lifting rope 21 is coupled to rotate the lifting winding roll 25 provided on the lifting shaft 23 to wind up the lifting code. In addition, a separate inclined rope 41 is used to vary the inclination angles of the plurality of light blocking wings 11 and 12. The lifting rope 21 and the inclined rope 41 both have a ring structure to implement opening and closing of the external optical path by pulling (rotating) in the forward or reverse direction.

On the other hand, in the following description "front" means the front of the housing 10 and "rear" means the back of the housing 10. The forward pull of the lifting rope 21 and the slope rope 41 is defined as lowering the front row and the reverse pulling is defined as lowering the rear row. The forward (forward) inclination of the light shielding wings 11 and 12 is inclined forward, and the backward (reverse) inclination is defined as inclined backward.

According to the present invention, the shielding blades 11 and 12 are provided with inclined cords 31 and 32 for supporting them separately. The inclined cords 31 and 32 are positioned at front positions through the front strings 31a and 32a disposed forward, rear strings 31b and 32b disposed rearward, and connecting lines (not shown) disposed therebetween. The light shielding wings 11 and 12 are supported.

In this case, the first inclination code 31 of the present invention can support the odd number of first shielding blades 11 in an interlockable manner, and the second inclination code 32 can link the even-numbered rows of second shielding blades 12. Support structure. The first inclined cord 31 simultaneously supports the odd-numbered first light-shielding blades 11 such as the first row, the third row, and the fifth row, and the second inclined cord 32 has the second row and the fourth row. And even-numbered second light shielding wings 12 such as the sixth row and the like. Of course, this approach achieves the most balanced operation, but can be combined with other arrangements.

In addition, according to the present invention is provided with an inclined driver 40 for performing a rotational drive of the inclined shaft 43 by the forward and reverse direction of the inclined rope (41). The inclined driver 40 maintains the same in structure as the above-mentioned lifting driver 20, but reduces the size and fixes it to one side of the lifting driver 20. The inclined shaft 43 is fixed on the inclined driver 40 to transmit the pulling force of the inclined rope 41 to the light shielding wings 11 and 12. The inclined shaft 43 is easily configured to have a rectangular cross section. The inclined shaft 43 is rotatably supported through the support plate 14 inside the housing 10 together with the lifting shaft 23.

Further, according to the present invention, the winding means 50 for performing the forward or reverse inclination movement of the light shielding wings 11 and 12 in conjunction with the rotational direction of the inclined rope 41 is inclined winding on the inclined shaft 43. It is provided so that the 1st inclination cord 31 and the 2nd inclination cord 32 may be wound through the roll 51 and 52. As shown in FIG. In FIG. 1, the winding means 50 is disposed at two places of the housing 10 to support the respective inclined cords 31 and 32, but may be expanded as the length of the light shielding wings 11 and 12 increases. Do. The first light blocking wing 11 and the second light blocking wing 12 implement the inclined motion in different patterns by the winding means 50.

3 (b) and 9 (a), the winding means 50 of the present invention has a double overlapping state in which the shielding blades 11 and 12 neighboring each other up and down at the neutral position of the inclined rope 41 are respectively. Keep it. When the light shielding vanes 11 and 12 of the first row and the second row overlap and the light shielding vanes 11 and 12 of the third row and the fourth row overlap with each other in a double overlapping state, the light path is opened at the maximum. It is defined as the "neutral position" of the slope rope (41). Of course, the neutral position of the inclined rope 41 is also the neutral position of the inclined shaft 43 and the neutral position of the inclined driver 40. As described above, the present invention can greatly improve light efficiency and viewability as compared with the prior art when the light shielding wings 11 and 12 are fully opened.

In FIG. 3, the first inclination code 31 and the second inclination code 32 are shown without being separated for convenience of understanding, but are actually separately configured and mixed as described above.

The winding means 50 of the present invention is the front inclined cord 32a and the first inclined cord of the second inclined cord 32 on the right inclined winding roll 52 for the forward oblique movement of the light shielding wings 11 and 12. The rear strap 31b of the 31 is fixed, and the front strap 31a and the first strap of the first inclined cord 31 are attached to the left inclined winding roll 51 for the inclined movement of the light shielding wings 11 and 12. 2 Fix the rear strap 32b of the inclined cord 32. The right inclination winding roll 52 is for forward driving of the light shielding vanes 11 and 12, and the left inclination winding roll 51 is for reverse driving of the light shielding vanes 11 and 12. Of course, this may be configured oppositely. In FIG. 3A, the front strap 32a of the second slope cord 32 is fixed to the front, and the rear strap 31b of the first slope cord 31 is fixed to the rear. In FIG. 3C, the front strap 31a of the first inclination cord 31 is fixed to the front, and the rear strap 32b of the second inclination cord 32 is fixed to the rear. In order to fix the inclined cords 31 and 32, a spiral groove 58 is formed on the outer circumferential surface of the inclined winding rolls 51 and 52, and a screw 68 is used. At this time, the front strap (31a) and the rear strap (32b) prevent the twisting of the front strap (31a) and the rear strap (32b) and detachment to the outside of the take-up roll in the left and right inclination winding rolls (51, 52), respectively, In order to allow the distance to be greatly wound, it is preferable to be wound in an "X" shape.

Accordingly, as shown in FIGS. 3A and 9B, when the inclined rope 41 is pulled forward, the rear strap 31b of the first inclined cord 31 is raised and the second inclined cord 32 is raised. Lower the front strap 32a of the front to implement the inclination of the light shield wings (11, 12), the front strap of the first inclined cord 31 when the inclined rope 41 is pulled in the reverse direction as shown in FIG. 31a) while raising the rear strap 32b of the second inclined cord 32 to implement the rearward inclination of the light shielding wings 11 and 12.

The winding means 50 of the present invention interlocks the left inclination winding roll 51 and the right inclination winding roll 52 via the intermediate shaft 65. The intermediate shaft 65 forms a square groove engaged with the inclined shaft 43 and is coupled by fitting. The left inclination winding roll 51 and the right inclination winding roll 52 are coupled to and interlocked with the intermediate shaft 65 simultaneously using a central boss. The inclined winding rolls 51 and 52 and the intermediate shaft 65 may use the same synthetic resin material.

As a detailed configuration, the inclined winding rolls 51 and 52 are provided with an arc-shaped groove 56 on the boss to perform play with the stone pieces 66 formed on the outer circumferential surface of the intermediate shaft 65. The arc-shaped groove 56 is formed at an angle (for example, 135 degrees) on the inner bosses of the respective inclination winding rolls 51 and 52. The protrusion piece 66 of the intermediate shaft 65 is formed in the dimension accommodated in the arc-shaped groove | channel 56 of both inclination winding rolls 51 and 52. As shown in FIG. As the clearance of the rotational movement is formed by the arc-shaped groove 56 and the stone piece 66, the delay of the timing at which the rotation of the inclined shaft 43 is transmitted to the left inclination winding roll 51 and the right inclination winding roll 52 is reduced. This is defined as 'gap movement'. This clearance movement is to maintain the operation reliability even in rapid forward and reverse driving by sufficiently securing the 'neutral position' which is the intermediate zone between the forward and reverse movement of the light shielding wings (11) (12).

As a detailed configuration, in Figs. 7 and 8, the inclination winding rolls 51 and 52 are coupled via a spring 63 to cushion relative motion. Even if the 'neutral position' is sufficiently secured between the left inclination winding roll 51 and the right inclination winding roll 52, when the inclined rope 41 is rapidly operated in the forward and reverse directions, a shocking operation can be made. In order to prevent this, a pinhole 54 is formed in each of the inclination winding rolls 51 and 52, and a torsion type spring 63 is installed through the pinhole 54.

As a detailed configuration, in Figs. 7 and 8, the left inclination winding roll 51 and the right inclination winding roll 52 are provided with locking pieces 55 at the end portions respectively to limit the rotation angle. The locking piece 55 protrudes from the outer end of the inclination winding rolls 51 and 52 and engages with the locking grooves 71 and 72 of the locking plate 70 to limit the rotation angle. The locking plate 70 is provided to be adjacent to each of the inclination winding rolls 51 and 52. Accordingly, the angle of the light shielding wings 11 and 12 is inclined by the forward and backward pulling of the inclined rope 41 to prevent failure due to excessive operation. In FIGS. 4 to 6, the profiles of the locking grooves 71 and 72 are formed to be symmetrical on both sides of the locking plate 70, but may be set differently according to the forward and backward inclination angles of the light shielding wings 11 and 12. have.

As a detailed configuration, the inclined winding rolls 51 and 52 are formed in the same structure and are coupled through the flange 61 formed at one side. The left inclined winding roll 51 and the right inclined winding roll 52 are formed in the spiral groove 58 for fixing the arc 68, the pinhole 54, the locking piece 55, as well as the screw 68 as described above. All elements can be formed identically. That is, except that the flange 61 on one side can be produced in the same mold with each other. 4 to 6 illustrate the flange 61 on the left inclination winding roll 51 as shown on the opposite side to FIG. 1 (FIG. 2).

Separation piece 75 is provided so that the inclination of the inclination cords 31 and 32 may not occur in the middle of the inclination winding rolls 51 and 52. The separating piece 75 includes a front strap 32a and a rear strap 32b positioned on the right inclination winding roll 52 and a front strap 31a and rear strap 32b on which the left strap 31b is located on the left inclination winding roll 51. Keep it separate to avoid tangling. Separation piece 75 is installed so as not to interfere with the flange 61 of the inclination winding rolls 51 and 52. Accordingly, even when the inclined rope 41 is rapidly operated in the forward and reverse directions, operation reliability can be ensured.

In operation, the forward inclination movement of the light shielding blades 11 and 12 will be described with reference to FIG. 3 with reference to FIG. 9. The secondary light wing (12) is to open the optical path as much as possible in a double layer, and when the inclined rope 41 is pulled in the forward direction, the left inclination winding roll (51) is the locking piece 55 at the limit of the locking groove 71 It restrains and stops, and starts to rotate at the time when the right inclination winding roll 52 is set by the play movement, by the downward of the front strap 32a and the upward of the rear strap 31b (rear strap 32b and the front). When the string 31a adheres to the current position, the forward tilting motion of the light shielding wings 11 and 12 is induced, and the locking piece 55 of the right tilt winding roll 52 reaches the limit of the locking groove 72. The light shielding blades 11 and 12 are inclined to the maximum. In this state, when the inclined rope 41 is pulled in the reverse direction, the inclined rope 41 proceeds in the reverse order to become the neutral state of FIG.

If the inclined rope 41 continues to be pulled in the reverse direction in the neutral state of FIG. 9 (c), as shown in FIG. 3 (c), the right inclination winding roll 52 is the locking piece 55 and the locking groove 72 at this time. The left inclined winding roll 51 is rotated in the restrained state by performing the reverse inclination movement of the light shielding wings 11 and 12 by the same principle.

In FIG. 9, the front strap 31a-front strap 32a and the rear strap 31b-rear strap 32b are shown without distinction for convenience of understanding but are actually configured separately and mixed.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined by the appended claims. It is therefore intended that such variations and modifications fall within the scope of the appended claims.
