JP-A-2007-9485

In the blind operating device disclosed in Patent Document 1, the holder is inserted into the groove of the weight bar, slid in the longitudinal direction of the weight bar, and moved to a desired position for attachment. However, depending on the material of the weight bar or holder and dimensional changes due to manufacturing conditions, frictional resistance is generated when the holder is slid to a desired position. For this reason, it was not possible to easily move it to a desired position, and there was a problem with assembly.

SUMMARY OF THE INVENTION The present invention has been made in view of such problems. To provide a blind operating device capable of being moved to a position and having improved assemblability.

In order to solve the above-mentioned problems, according to a first aspect of the present invention, there is provided an operation device for blinds attached to a weight bar connected to a lower end of a shielding material, wherein the weight is attached to open and close the shielding material. A blind operating part hanging down from a bar and a holder holding the blind operating part within the weight bar, the holder being movable within the weight bar by rotating within the weight bar There is provided an operating device for blinds characterized by switching between a free state and a locked state fixed to the weight bar.

According to such a configuration, the holder rotates within the weight bar, thereby changing the posture of the holder and changing the size (height, width, etc.) in the direction in which it is fixed within the weight bar. In this manner, switching is made between a free state in which movement is possible within the weight bar and a locked state in which the weight bar is fixed. Therefore, the holder can be fixed after being easily moved to a desired position, and the ease of assembly can be improved.

Various applications are possible for the present invention. For example, the holder may be accommodated in the weight bar when the holder is changed from the free state to the locked state. According to such a configuration, the holder does not protrude from the weight bar and is inconspicuous in the locked state, so that the design can be improved.

Further, the blind operation portion is pulled downward to open and close the shielding material. The pulling directions of the blind operating parts may be the same. Even if the user pulls the blind operating portion downward, the rotating direction of the holder coincides with the locked state, so that the locked state can be prevented from being released. Also, the holder can be prevented from moving in the lateral direction within the weight bar.

Further, the weight bar is formed with a mounting space portion in which the holder is arranged, and the holder includes a first locking portion and a second locking portion that lock into the mounting space portion. The locking portion is locked to the ceiling portion of the mounting space portion in the locked state, and is unlocked from the ceiling portion in the free state, and the second locking portion is in the locked state. It may be engaged with the lower portion of the mounting space portion at times, and the engagement with the lower portion may be released in the free state. The holder can move smoothly in the mounting space and can be stably fixed in the mounting space.

Further, the first engaging portion may have a protrusion that contacts the ceiling portion of the mounting space. Since a click feeling is generated when the protrusion contacts the ceiling, it is possible to confirm that the first locking part is locked to the ceiling. Further, since the contact surface with the ceiling portion is small, the pressing force of the first locking portion is large, so that it can be firmly fixed.

Further, the holder may be provided with first unlocking means for operating switching from the locked state to the free state. It is possible to change the fixed position of the holder by releasing the locked state by the first unlocking means.

Further, an operation piece for pulling, pushing, or rotating the holder may be provided, and the first unlocking means may also be used as the operation piece. For example, when the operating piece is rotated in a direction away from the weight bar, the locked state of the holder can be released.

Further, the holder may be formed with an insertion portion through which the blind operation portion is inserted on the side opposite to the operation piece with respect to the center of rotation. Since the blind operation part is inserted through the insertion part, it is possible to prevent the blind operation part from being detached from the holder.

Further, the holder is provided with second unlocking means for switching the holder from the locked state to the free state on the side opposite to the operation piece with respect to the center of rotation. A guide portion for guiding the blind operation portion to the insertion portion may be formed in the second unlocking means. The blind operation part can be guided to the insertion part through the guide part formed in the second unlocking means. Further, when the second unlocking means is operated, for example, by pressing, the holder can be brought into a free state.

Further, a restriction portion may be provided between the insertion portion and the guide portion for restricting the blind operation portion from being detached from the insertion portion. Since the movement of the blind operating part can be restricted by the restricting part, the blind operating part can hang down in a stable state.

According to a second aspect of the present invention, there is provided a blind operating device attached to a weight bar connected to a lower end of a shielding material, wherein the blind operating device hangs down from the weight bar to open and close the shielding material. and a holder for holding the blind operating portion within the weight bar, wherein the holder is partly changed in posture within the weight bar to move within the weight bar in a free state. , a locked state fixed to the weight bar, and a blind operating device.

According to such a configuration, the holder changes its size (height, width, etc.) in the fixing direction in which it is fixed in the weight bar by changing its posture in the weight bar. In this way
It is switched between a free state in which it can move within the weight bar and a locked state in which it is fixed to the weight bar. Therefore, the holder can be fixed after being easily moved to a desired position, and the ease of assembly can be improved. The second aspect of the present invention can also be applied in the same manner as the first aspect of the present invention.

ADVANTAGE OF THE INVENTION According to the present invention, the operating device for blinds is improved in assembling efficiency because frictional resistance is less likely to occur when the holder is slid and moved to the desired position, and the holder can be easily moved to the desired position. is provided. Other effects of the present invention will also be described in the mode for carrying out the invention, which will be described later.

Further, in the holder 140, a guide portion 144d for guiding the pull cord 130 to the insertion portion 142d is formed in the second unlocking means 144c provided on the opposite side of the operation piece 144a with respect to the rotation center. It becomes easy to guide the pull cord 130 to the insertion portion 142d through the guide portion 144d formed in the unlocking means 144c. Also, the holder 140 can be unlocked from the weight bar 120 by performing an operation such as pressing the second unlocking means 144c.

In addition, by providing a restriction portion 144e between the insertion portion 142d and the guide portion 144d to restrict the pull cord 130 from coming off the insertion portion 142d, the pull cord 130 can move in the longitudinal direction of the weight bar 120. Since the movement can be restricted, the pull cord 130 can be suspended in a stable state.

In addition, since the projection 142a is provided to contact the ceiling 120b of the mounting space 120a, the projection 142a contacts the ceiling 120b to give a click feeling. Therefore, it can be confirmed that the projecting portion 142a is engaged with the ceiling portion 120b. Further, since the contact surface with the ceiling portion 120b is small due to the protrusion 142a, the pressing force is increased.
