Therefore, the support cover 11 is fixed to the top side case 1 by the ribs 32 fitted in the positioning groove 31 and the locking protrusions 33a or 33b engaged with the ribs 34.

As shown in FIG. 3, in the horizontal louver as described above, the winding shaft 7 and the support member 6 disposed at positions near the both end portions of the top side casing 1 are switched in the left-right direction. That is, the winding shaft 7 extends from the support position of the inclined drum 9 toward the center portion of the top side casing 1.

According to this configuration, the suspension position of the ladder belt and the lifting cord 5 serves as a step between the ends of the top side casing 1 without securing the accommodation of the winding shaft 7, so that the ladders supported on the both sides of the blade 3 are provided. The belt 2 is placed at a position near the end of the blade 3, so that the end portion of the blade 3 can be prevented from sagging due to its own weight.

Only the elevating shaft 8 is inserted into the support member 6 in a state in which the winding shaft 7 and the inclined drum 9 are supported, and is formed symmetrically with each other in the front-rear direction, so that it is not provided even if it is switched in the left-right direction.

Further, the support cover 11 supporting the common inclined drum 9 and the drive gear 13 is attached to the support member 36, and the lift shaft 8 is inserted into the inclined drum 9, and the tilt shaft 12 is inserted into the drive gear 13.

With the rotation of the tilting shaft 12 and the lifting and lowering of the ladder belt 2 by the driving gear 13, the driven gear 10, and the inclined drum 9, the operation of the rotating blade 3 can be performed.

In the ladder hanger device 35, since the common support cover 11 is used, the tilting shaft 12 can be supported even in the case where the top side casing 1 is rotated in the left-right direction as in the above description. .

Hereinafter, the configuration of the operation unit 14 will be described with reference to Figs. 4 to 9 . As shown in FIGS. 4 and 5, in the operation unit 14, a pulley housing 36 is attached to one side of the clutch housing 35, and a pulley 16 is rotatably supported in the pulley housing 36. Further, an operation chain 17 is hung on the pulley 16, and the pulley 16 is rotated by the operation of the operation chain 17.

As shown in FIG. 7, the pulley 16 is integrally provided with a spur gear drive gear 37. The drive gear 37 rotates in the inner casing 38, wherein the inner casing 38 is supported by the clutch housing 35 and the pulley housing. Within 36.

The inner casing 38 is rotatably supported by a transmission shaft (second output shaft) 39 that transmits a first transmission gear 40 in which a spur gear is integrally formed at a base end portion of the shaft 39, and a second transmission gear 41. Further, as shown in FIGS. 6 and 9, the first transmission gear 40 meshes with the drive gear 37.

The number of teeth of the first transmission gear 40 is larger than the number of teeth of the drive gear 37. Thereby, the rotational speed of the pulley 16 is decelerated and transmitted to the transmission shaft 39. Further, as shown in FIG. 6, the transmission shaft 39 is located obliquely below the pulley 16, and is located on an extension of the inclined shaft 12. Further, a hexagonal hole 42 is formed in a central portion of the front end side of the transmission shaft 39 to constitute a second output shaft, and is connected to the input shaft of the tilting unit 15 in the hexagonal hole 42.

The second transmission gear 41 is disposed adjacent to the first transmission gear 40, and has a smaller number of teeth than the number of teeth of the first transmission gear 40. A lifting gear 43 of a spur gear that meshes with the second transmission gear 41 is rotatably supported in the inner casing 38. Further, as shown in Fig. 6, the lifting gear 43 is rotatably supported at an obliquely upward position of the transmission shaft 39, and as shown in Fig. 8, is rotated about a fixed shaft 45 supporting the first clutch device 44. Since the number of teeth of the lifting gear is larger than the number of teeth of the second transmission gear 41, the rotation of the transmission shaft 39 is decelerated and transmitted to the lifting gear 43.

The first clutch device 44 communicates the rotation of the lift gear 43 to the second clutch device 46, which communicates its rotation to the first output shaft 47. The center of rotation of the first output shaft 47 is the same as the center of rotation of the lift gear 43, and is the same as the center of rotation of the lift shaft 8. Further, an end portion of the elevating shaft 8 is fitted to the hexagonal hole 48 provided at the front end of the first output shaft 47.

The first clutch device 44 includes a function of rotating the shaft 39 by the tilting unit 15 when the transmission shaft 39 is rotated, that is, during the period in which the blade 3 is rotated to the fully closed state or the reverse fully closed state. The function of the lifting shaft 8 is not rotated.

When the lift gear 43 is rotated in the direction of the pull-up blade 3 after the blade 3 is rotated to the fully closed state, the first clutch device 44 and the second clutch device 46 transmit their rotation to the lift shaft 43.

Moreover, when the lift gear 43 rotates in the direction of the pull-up blade after the blade 3 is rotated to the fully closed state, the second clutch device 46 can prevent the self-weight due to the blade 3 and the bottom rail 4 even if the hand is released from the operating chain 17. The rotation of the lifting shaft 8.

Further, when the lift gear 43 is rotated toward the blade falling direction after the blade 3 is rotated to the reverse full close state, the second clutch device 46 allows the rotation of the lift shaft 8 due to the weight of the blade 3 and the bottom rail 4.

(1) Since the lift shaft 8 and the tilt shaft 12 are provided in the top side casing 1, and the tilt shaft 12 is disposed at the lower corner of the top side casing 1, the enlargement of the top side casing 1 can be suppressed.

(2) The tilting roller 9 that rotates coaxially with the winding shaft 7 is rotated by the driving gear 13 attached to the tilting shaft 12, so that the enlargement of the top side casing 1 can be suppressed.

(3) The rotation of the pulley 16 is transmitted to the transmission shaft 39 by the spur gear, and is transmitted from the transmission shaft 39 to the lifting shaft 8 by the spur gear. Further, since the center of rotation of the pulley 16, the center of rotation of the transmission shaft 39, and the center of rotation of the lift shaft 8 are arranged in a non-linear shape, the size of the casing of the operation unit 14 accommodating these members can be reduced.

(4) The rotation of the pulley 16 is decelerated by the spur gear and transmitted to the transmission shaft 39, and the rotation of the transmission shaft 39 is decelerated by the spur gear and transmitted to the lifting shaft 8, so that the pulley 16 can be sufficiently The rotation is decelerated, and the rotational torque can be transmitted to the lifting shaft 8 more effectively than the planetary gears. Therefore, the operation force can be reduced when the operation of the pull-up blade is performed, and the size of the casing can be reduced compared to the operation unit having the planetary gear as the reduction gear.

(5) Even if the support member 6 supporting the winding shaft 7 is disposed in the left-right direction in the top side casing 1, the drive gear 13 is supported to the support by the support cover 11 attached to the support member 6. In either of the holes 28a, 28b, a common support cover 11 can also be used for the correspondence. Therefore, even if the support member 6 is provided in the left-right direction, the same support cover 11 can be used.

(6) The locking projections 33a and 33b of the support cover 11 are provided at equal distances from the center of the lifting shaft 8 and the inclined drum 9, so that even if the support cover 11 is switched in the left-right direction, the locking projection can be provided. Any one of the portions 33a, 33b is engaged with the rib 34 of the top side case 1, so that the support cover 11 can be fixed to the top side case 1.
