The support shaft is fitted into a bearing hole formed in the side frame, and a nut is screwed onto the tip of the support shaft to prevent it from coming off, and each louver is operated to drive the louver. Because the louvers were connected to the body with links, it took time and effort to install them at the construction site, and it also took time and effort to remove them for cleaning, etc.

Means for Solving the Problems As a means for solving the above problems, the louvered blind of the present invention has a large number of louvers extending in parallel between the side frames on both sides of the window frame. A longitudinal guide of the louver is formed in the section, a connecting member connecting the end of the louver to the side frame is slidably fitted in the guide, and the connecting member is connected to the side frame. protruding a slotted hollow support shaft having a link that engages with an operating body that is freely slidable along the side frame, and a locking portion that locks onto the edge of a bearing hole formed in the side frame; A reinforcing rod that is inserted into the support shaft so as to be able to move forward and backward is mounted, and the support shaft is pushed into the bearing hole by the swinging of the connecting member and the reinforcing rod is inserted into the support shaft. The shaft is pivotally supported on the side frame, and
The link is engaged with the actuating plate as the connecting member slides, and each louver is tilted by sliding of the actuating body to change the degree of opening.

Functions and Effects The present invention has the above-mentioned structure, and when installing the louver, the connecting member fitted to the guides at both ends of the louver is moved inward from the edge of the louver, and the reinforcement attached to the connecting member is moved inward from the edge of the louver. After the rod is moved back and removed from the support shaft, and the louver is passed between both side frames of the window frame, the connecting member is moved to the outside, and the diameter of the support shaft is reduced against the elasticity while being attached to the side frame. When the louver is pushed into the bearing hole, the diameter of the support shaft expands due to the restoring elasticity when the locking part passes over the bearing hole, and the locking part locks on the rim of the bearing hole, causing the end of the louver to is connected to the side frame, and then the reinforcing rod is advanced and inserted into the support shaft, the support shaft is supported by the side frame in a state where the diameter cannot be reduced, and the above-mentioned connection member is prevented from moving outward. At the same time, the link projecting from the connecting member engages with the actuating body for driving the louver, and when the actuating body is slid in this state, each louver tilts around the support shaft to change the opening degree. ,
When removing the louver, pull the reinforcing rod back from the inside of the support shaft so that the diameter of the support shaft can be reduced, and then pull the connecting member inward from the edge of the louver to reduce the diameter of the support shaft. At the same time, the link and the operating body are disengaged from each other, the connecting member is removed from the side frame, and the louver is removed.

In this way, with this invention, the louver can be attached by simply moving the connecting member fitted into the louver guide outward, pushing the support shaft into the bearing hole of the side frame, and then inserting the reinforcing rod into the support shaft. Also, the louver can be removed by simply pulling out the reinforcing rod from inside the support shaft and moving the connecting member inward.
The work of attaching and detaching the louvers can be done extremely quickly and easily, and in the installed state,
Since the reinforcing rod is inserted into the support shaft, the support shaft is reinforced, and by holding the support shaft so that its diameter cannot be reduced, a force is applied to the connecting member to push it inward from the edge of the louver. Even in this case, the locking portion is securely locked to the rim of the bearing hole and does not come off, and the louver can be firmly attached.
