JPS608076Y2 - slanted window blinds - Google Patents

Description

[Detailed explanation of the invention] When installing Venetian blinds on a sloped window, if the slope is less than 30' due to a skylight, etc., the entire blind will droop and the slope will need to be adjusted (
opening/closing) becomes difficult.

This invention was devised for the purpose of obtaining a blind that does not have the above-mentioned drawbacks and can be applied to windows that are horizontal or sloped below 30'.The structure of the blind will be explained with reference to the drawings.
Figure 1 is a plan view of the proposed slanted window blind - Example, Figure 2 is a side view of the ladder cord attachment part, Figure 3 is a side view of the guide cord attachment part of the slat, and Figure 4 is the slat and ladder cord. FIG. 3 is a perspective view showing the relative positions of the guide cord and the guide cord.

In the drawing, 1 is a window frame, 2 is a top rail, and 3 is a ladder cord, the upper end of which is wrapped around a drive wheel provided in the rail, several tiers of slats 4 are placed in the middle, and a bottom bar 5 is attached to the lower end.

Reference numeral 6 denotes shaft parts provided at the left and right ends of the bottom bar, which are held by bearings 9 that move forward and backward on a rail 8 attached to a seat plate 7 attached to the lower window frame. Allow it to be fixed in position.

Reference numeral 11 denotes a guide cord for the slat, which is made of a strong and slippery string made of polymer compound material, and is attached to a washer 12 whose upper end is provided inside the top rail. The lower end of the cord is passed through the threaded pipe 14, and the threaded pipe is fitted onto a seat plate 15 attached to the lower frame of the window. 17 is a coat hanging stopper, 18 is a glass plate, and 19 is a drive wheel.

If the window is small, it is sufficient to install a pair of ladder cords and slat guide cords on each side of the bottom bar and slats, but if the window becomes large, the slats will become wider on the left and right sides, and the middle will sag. , it becomes necessary to arrange a guide cord also in the middle.

In this case, as shown in FIG. 1, the bottom bar is divided into left and right parts in the middle, and slidingly adjustable bearings are provided at each divided end.

Even if this blind is installed on a skylight with a gentle slope,
Adjust the positions of the bearing 9 and threaded pipe 14 to connect the ladder cord 3.
And if the guide cord 11 of the slat is kept taut,
Since each slat 4 is held in the same normal position as when the blind is hung vertically, each slat can be opened and closed accurately by operating the drive wheel 19 attached to the top of the ladder.

Claims (1)

[Scope of utility model registration request] In a blind with several slats placed in the middle of a ladder cord pulled out from the top rail and a bottom bar attached to the bottom end, shafts are provided at both left and right ends of the bottom bar, which are held in bearings that can be adjusted forward and backward attached to the window sill. Separately, pull out the guide cords of the slats from the left and right sides of the top rail, pass them through the long holes in the longitudinal direction drilled in the slats of each step, attach a threaded pipe to the lower end, and attach the threaded pipes to the window sill. A sloped window blind consisting of a threaded pipe with a nut attached below the fitting part that fits into the seat plate attached to the seat plate.
