Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an improvement of a guide wire attaching device for a Venetian blind installed in a tilted window.

[Prior Art] Venetian blinds installed on skylights and inclined windows can be opened or closed horizontally or diagonally. Therefore, as shown in Japanese Utility Model Publication No. 62-201296, the upper end of the guide wire is fixed to the upper frame of the window. The lower end of the head rail is fixed to a fixture fixed to the lower frame.

[Problems to be solved by the invention] Since the fixture is fixed to the lower frame of the window on site, it is difficult to accurately position and adjust the fixing position. If the position of the fixture is displaced, the axis of the stretched guide wire and the centers of the through holes of the slat and the bottom rail do not coincide with each other, which causes a problem that the opening and closing of the Venetian blind is not smooth. Further, when the Venetian blind is completely closed, the bottom rail comes into contact with the fixture, and a gap is generated between the bottom rail and the lower frame, so that there is a problem that complete light shielding cannot be performed.

The present invention has been made to solve these problems, and its purpose is to keep the guide wire stretched so that it always passes through the center of the through hole of the slat and the bottom rail, and It is an object of the present invention to provide a guide wire mounting device for a Venetian blind for a skylight tilted window in which a gap for leaking light does not occur between lower frames.

[Means for Solving the Problems] In order to achieve the above object, the present invention adopts
In a Venetian blind installed in a slanted window, a frame bracket is fixed to the lower frame of the slanted window, and the bottom frame is attached to the frame bracket so that the bottom frame is in close contact with the lower frame and is slidable left and right. The lower stopper of the guide wire that guides the slat and the bottom rail is fixed beforehand. It is desirable that the bottom rail be provided with an upper edge portion projecting from the upper surface thereof so that when the blind is closed and the bottom rail comes into contact with the bottom frame, the upper edge portion overlaps the bottom rail in the front-rear direction.

[Operation] Since the bottom frame can slide to the left and right with respect to the frame bracket fixed to the lower frame, it is extremely easy to slide the bottom frame to the left and right to place the lower stopper in a predetermined position. is there. When the lower stopper is in a predetermined position, the guide wire passes through the center of the through hole of the slat and the bottom rail, so that the blind can be opened and closed smoothly. Since the bottom frame is in close contact with the lower frame, there is no light leak space between the lower frame and the bottom frame. Further, since the upper edge of the bottom frame overlaps with the bottom rail in the front-rear direction, that is, in the direction orthogonal to the window surface, there is no space for light leakage between the bottom rail and the bottom frame when the blind is closed.

[Embodiment] The present invention will be described based on an embodiment shown in the drawings.

As shown in FIGS. 1 and 2, the head rail 11 of the blind 10 is fixed to the upper frame 13 of the window via the head rail bracket 12, and the ladder cord 14 and the lifting cord 15 extend from the head rail 11. A ladder-shaped ladder cord 14 supports each slat 16, and a lifting cord 15 pierces each slat and hangs the bottom rail 17 at the bottom. A tilt shaft 18 penetrates through the head rail 11, and a hollow operation rod 19 that rotationally drives the tilt shaft hangs down from the head rail 11. Although not shown, the upper end of the ladder cord is fixed to the drum attached to the tilt shaft, and the tip of the elevating cord is pulled out from the hollow operation rod. Hollow operating rod
When 19 is rotated, the slats 16 tilt, the bottom rail 17 rises when the knob 20 at the tip of the lifting cord 15 is pulled, and when the lock of the hollow operating rod 19 is loosened, the bottom rail 17 descends and the lock is released when released. The hanging bottom rail 17 stops.
The hollow operation rod 19 is hooked on the window frame by a ball chain 21.

An upper end of a guide wire 23 is fixed to an upper stopper 22 in the head rail 11, and the guide wire goes out of the head rail 11 and penetrates each slat 16 and a bottom rail 17. The lower end of the guide wire 23 is wound and fixed on a lower stopper 24 attached to the bottom frame 30. The bottom frame 30 is slidably attached to a frame bracket 40, and the frame bracket is fixed to the lower frame 25 of the window with screws 41.

As shown in FIG. 3, the bottom frame 30 is an irregularly shaped mold having an opening 32 at the center of the bottom portion 31, and the rear side portion 33 projects higher than the upper side portion 34 to form an upper edge portion 35. To do. Both edges of the opening 32 are bent upward to form a ridge 36. The upper side portion 34 is provided with a fastener hole 37, and the worm case upper surface protruding portion 38 of the lower fastener is fitted into the fastener hole.

The frame bracket 40 is a box-shaped body made of a highly elastic synthetic resin and having an open upper surface, and a cylindrical portion 42 surrounding the screw hole of the screw 41 is provided in the center. Bottom of frame bracket 40
Two grooves 44 are formed on the front and rear, which extend to the left and right. Both side portions 46 of the frame bracket 40 are thick, but the front and rear side portions 47 are thin and elastically bulge in the front and rear direction.
The height of the frame bracket 40 is lower than the inner height of the bottom frame 30, but the front-rear width is slightly larger than the front-rear inner width of the bottom frame 30. When the frame bracket 40 is pushed into the bottom frame 30, the front and rear sides 47 are recessed, the bottom side 43 is fitted in the opening 32, and the groove 44 is fitted in the ridge 36. In this state, the bottom frame 30 is held by the elasticity of the front and rear sides 47 of the frame bracket 40, but can be slid to the left and right.

As shown in FIG. 4, the lower stopper 24 attached to the bottom frame 30 includes a warm case 26, a winding set 27, and a case cover 28.
A worm mechanism is provided on the wheel shaft 29, and the tip of the guide wire 23 is wound around the wheel shaft 29. The upper surface protruding portion 38 of the worm case 26 fits into the fastener hole 37 of the bottom frame 30.

As shown in FIG. 3, since the worm shaft 39 of the winding set projects from the upper surface protruding portion 38, it is possible to rotate the worm shaft 39 from above the bottom frame 30 to wind and tension the guide wire 23. .

Generally, the two frame brackets 40 are screwed to the lower frame 25, but since the front and rear width of the lower frame 25 is significantly smaller than the left and right width, the front and rear fixing positions of the two frame brackets are relatively accurate. is there. Therefore, the positions of the bottom frame 30 attached to the frame bracket 40 and the lower stoppers 24 fixed to the bottom rails in the front-rear direction are also accurate.
Since the bottom frame 30 is slidable left and right, it is easy to make the position of the lower stopper 24 in the left-right direction correspond to the upper stopper 22. The slats 16 that open and close when the guide wire 23 is stretched by making the positions of the upper stopper 22 and the lower stopper 24 correspond exactly to each other.
Since the center line of the through hole of the bottom rail 17 and the axis of the guide wire 23 are aligned with each other, the slat 16 and the bottom rail 17 move smoothly along the guide wire 23, so that the blind opens and closes lightly.

The bottom frame 30 is in close contact with the lower frame 25, and when the blinds are closed, the bottom rail 17 and the upper edge of the bottom frame 30
Since 35 overlaps in the front-rear direction, that is, in the direction orthogonal to the window surface, the bottom rail 17 and the lower frame 25 are completely shielded, and there is no possibility that light will leak from the lower side of the bottom rail 17.

[Advantage of Invention] As described above, in the device of the present invention, it is not easy to adjust the position of the guide wire because the lower stopper of the guide wire is directly fixed to the lower frame. Differently, a bottom frame that can be slid left and right closely attached to the lower frame is provided, and the position of the guide wire can be easily adjusted with respect to the slat and the bottom rail on the bottom frame to ensure smooth opening and closing of the blinds. It has an excellent effect that it can.

In addition, the bottom frame with the upper edge has a special effect that complete light shielding is possible when the blinds are closed because there is no gap between the bottom rail and the lower frame for light to leak. To be
