Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to improvement of a slat angle adjusting device for a blind with a built-in partition device, and more specifically, for adjusting the slat angle at a predetermined height position in front of the partition device. The present invention relates to a slat angle adjusting device that can be performed.

[Conventional technology]

A conventional slat angle adjusting device for a blind incorporated in a frame device such as a partition device or a window frame has its operation portion set at a predetermined height position of the frame body from the viewpoint of operability and appearance, and the operation portion is rotated. As a result, a power transmission mechanism that interlocks the power with the slat rotation device in the body of the blind is provided inside the frame, and as the power transmission mechanism, as disclosed in Japanese Utility Model Laid-Open No. 58-165189, The lower end of the transmission shaft rotatably hung in the frame and the operating wheel having the horizontal shaft of the operating portion are linked by a worm gear, and the upper end of the transmission shaft and the slat angle adjusting shaft of the blind body are also connected. Since the mechanism is linked by a worm gear, the structure is complicated and the assembly work is troublesome, and the cost tends to be high. On the other hand, a mechanism in which a pulley fixed to the operation wheel and a pulley connected to the slat angle adjusting shaft are interlocked with a belt is considered to be inexpensive, but the adjustment of the slat angle is slightly angular. However, there is a problem in that the belt loosens after long-term use and slips between the belt and the pulley, making it impossible to set an accurate angle.

[Problems to be solved by the invention]

In view of the above situation, the present invention is to solve the problem that even if the belt is loose, there is no idle rotation of the belt even though the belt transmission method is structurally simple, easy to assemble, and can reduce cost. Moreover, it is an object of the present invention to provide a blind slat angle adjusting device with a built-in partitioning device, which can surely prevent the belt from falling off and can finely adjust the slat angle without aging.

A driving body integrally formed with a gear-shaped moving wheel and an operating wheel at a predetermined height position of the vertical frame forming the frame body in the vertical frame with the operating wheel partially protruding from the front opening of the vertical frame. A fixed body is rotatably mounted on the vertical frame, and an interlocking body having a gear-shaped driven wheel and a connecting portion for connecting the angle adjusting shaft is formed on the upper portion of the vertical frame by positioning the driven wheel in the vertical frame. A timing belt is rotatably pivotally mounted, a timing belt is meshed with the moving wheel and the driven wheel, and a contact plate for preventing the timing belt from slipping off is provided on a part of the outer periphery of the driving wheel and the driven wheel. And a blind with built-in partitioning device that is concentrically arranged close to the driven wheel. You configure the Tsu door angle adjustment device.
