Description of the Related Art Curtain material is suspended from a head box that is fixed to the upper frame of a window as one type of combing curtain, and a plurality of hoisting shafts are rotatably supported in the head box. The cord is hung, and the lower end of the lifting cord is attached to the lower part of the curtain.For example, by operating the operation cord that is hung from one end of the head box and rotating the winding shaft to move in the axial direction, the lifting cord is lifted. There is one in which the curtain material is raised and lowered by winding or rewinding in a spiral shape.

緊張された状態に維持されるため巻取軸を回転させなが

状に巻取りあるいは巻き戻すことが可能となる。In the above-mentioned tuck-up curtain, since the lifting cord is always kept in a tensioned state due to the weight of the bottom rail and the curtain material attached to the lower end of the curtain material, the winding shaft is always wound. It is possible to spirally wind or rewind the elevating cord by rotating the cord while moving it in the axial direction.

る。However, when the curtain cloth is lowered, if the bottom rail comes into contact with an obstacle and is unable to descend, and the winding shaft continues to rotate in the elevating cord rewinding direction, the tension state of the elevating cord is reduced. The lifting cord that is loose and loose around the winding shaft is stuck. Then, when the winding shaft is again rotated in the pulling direction of the curtain material in such a state, the lifting cord stagnant around the winding shaft is not wound in a spiral shape, and the lifting cord is lifted during the subsequent descent operation of the curtain material. It may not be possible to rewind normally.

い。Therefore, if the bottom rail comes into contact with an obstacle and the tension of the lifting cord is relaxed, an obstacle detection stop device is required to mechanically prevent the winding shaft from rotating.
Since the winding shaft moves in the axial direction while rotating when the curtain material is raised and lowered, an obstacle detection stopping device having such a simple structure for the winding shaft having such a structure has not been proposed yet.

An object is to provide an object detection stopping device with a simple configuration.

いる。As shown in FIGS. 4 and 5, the bearing member 8 rotatably supports the winding shaft 4 on an arcuate bearing surface 25 having an open upper portion. A locking member 26 is movably supported in the radial direction of the winding shaft 4 on the bottom surface of the bearing member 8 on the side of the bearing surface 25.
A locking piece 27 protruding upward is formed on one side. The locking member 26 is on the bottom surface in a range from a state in which the locking piece 27 is located on one side on the bottom surface of the bearing member 8 as shown in FIG. 4 to a state in which it is centrally located on the bottom surface as shown in FIG. In the state in which the locking piece 27 is movably supported at one side (non-operating position) on the bottom surface, the locking piece 27 does not engage with the groove 19 of the winding shaft 4, and the locking piece 27 is on the bottom surface. When it becomes possible to move to the upper center, the curtain material 3 of the winding shaft 4
On the basis of the rotation in the descending direction, that is, the rotation in the direction of arrow A shown in FIG. 4, the locking piece 27 engages with the groove 19 and moves to the center (operating position) on the bottom surface, and further movement is restricted. By doing so, the rotation of the winding shaft 4 is prevented.

In the state, the insertion hole 28 communicates with the insertion hole 29 formed on the bottom side of the bearing member 8. And
The lifting cord 5 wound around the winding shaft 4 has two insertion holes 2
8 and 29, the bearing member 8 and the head box 2 are guided downward, and when the lifting cord 5 is tensioned by the weight of the bottom rail 9 and the curtain material 3, the lifting cord 5 causes both insertion holes 28 and 29 to pass. It is designed to maintain communication.

れる。On the other hand, when the winding shaft 4 is rotated in the rewinding direction of the lifting cord 5, the lifting cord 5 is unwound from the winding shaft 4 and the curtain material 3 is lowered. At this time, when the bottom rail 9 or the curtain material 3 comes into contact with an obstacle to loosen the tension state of the elevating cord 5, the biasing force of the coil spring 31 causes the locking member 26 to move in the direction of arrow B in FIG. It is ready to move to. Then, as the take-up shaft 4 rotates in the rewinding direction, the recessed line 19 of the take-up shaft 4 and the locking piece 27 of the locking member 26 engage with each other and the engagement takes place as the take-up shaft 4 rotates. When the stop member 26 moves in the direction of the arrow B, and the locking member 26 is moved to the position shown in FIG. Rotation is blocked. Therefore, the rewinding of the lifting cord 5 in a relaxed state is prevented.

The lifting cord 5 is provided by the obstacle detection stopping device including the recessed line 19, the locking member 26, and the coil spring 31.
Since it is possible to prevent the rewinding of the lifting cord 5 when the tension of the lifting cord 5 is loose, the winding shaft 4 of the lifting cord 5 can be prevented.
It is possible to reliably prevent the occurrence of problems during the lifting operation due to the disorder of the winding state on the winding shaft 4.
Although the construction is such that the lifting cord 5 is spirally wound around the winding shaft 4 by moving it in the axial direction while rotating, the obstacle detection stopping device can be realized with an extremely simple structure.
