Description

[Detailed description of the invention] This invention has ropes installed in a loop shape that can be raised and lowered and fixed to the left and right ends of the bottom bar. This effectively prevents shaking and stirring caused by
It is suitable for installation mainly in outdoor areas such as windows, and
Unlike ordinary Venetian blinds, this Venetian blind can be installed on inclined surfaces or ceiling surfaces without the middle part sagging when unfolded, and can be freely raised and lowered, and has an extremely wide range of applications.

Generally, blinds are installed on the indoor side of windows in buildings, but especially in the summer, installing blinds on the outdoor side of the window has a much greater insulation effect against the light rays that shine through the glass, and it also reduces energy consumption for cooling. As a means, the latter is far superior to the former.

However, outdoor blinds have drawbacks such as being shaken and agitated by wind and rain, making noise, and being easily damaged. Conventionally, as a solution to these drawbacks, for example, the bottom bar and both ends of the slats of Venetian blinds are made with grooves. The bottom bar was slidably fitted into a shaped guide rail and moved up and down within the groove, but in this case as well, the bottom bar was free and only hung down due to its own weight, so it was vulnerable to wind and was easily blown away. It also had drawbacks such as getting wet and the presence of the guide rail spoiling the appearance.

In addition, all conventional Venetian blinds hang vertically due to the weight of the bottom bar during the unfolding operation, so if they are installed on an inclined surface or ceiling, the middle part will naturally droop when unfolding, and the unfolding operation will be difficult. cannot be done (
Because the bottom bar did not lower its weight, it could not be installed.

The present invention was developed in view of the above circumstances, and the lifting rope is tensioned and the bottom bar is fixed to the lifting rope so that it is forced to move up and down (deployment line support), so it is protected from wind and rain. The above-mentioned drawbacks of the conventional method have been overcome by making it possible to install it on an inclined surface or a ceiling surface without sagging or sagging, and at the same time to be able to smoothly operate the deployment line receiver. It is resolved.

One embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 indicates the entire Venetian blind.

2 and 2' are lifting ropes made of stainless steel wire whose surfaces are coated with a nylon resin film.

Reference numerals 3 and 3' designate elevating drive drums that are pivotally attached to the rotating shaft 5 near the left and right ends of the head box 4.

Reference numerals 6 and 6' denote pulleys, which are connected to a lower mounting bracket 9 by bolts 7 and nuts 8 fixed to a pulley mounting frame 19.

The metal fitting 9 is appropriately fixed to the lower outer side of the window frame 10, for example.

The lifting ropes 2, 2' go around the lifting drive drums 3, 3' and pulleys 6, 6', and pulleys 3a, 3b, 3C.
Two parallel filaments 2a, 2b with appropriate spacing are provided so that they can be rotated up and down.

The head box 4 is appropriately fixed to the upper outer side of the window frame 10, for example, by means of an upper mounting bracket 11.

The rotating shaft 5 is driven by a lifting gear 12, for example.

The elevating ropes 2, 2' and the bottom par 13 can be fixed by, for example, fixing the end of the linear 2a on one side of the rope 2 to the front and back sides near the left and right ends of the bottom par 13 using fixing members 14a, 14b. done by.

In this example, the filament 2a is an outer filament, and the other filament 2b is located on the inside.

As a result, the filaments 2b are difficult to see from outside when the blind 1 is unfolded, so that the appearance is not spoiled.

With the above-described structure, the nut 8 is rotated and the ropes 2, 2
By tensioning the bottom par 13, it is possible to completely prevent the bottom par 13 from shaking or wobbling due to wind and rain.

Further, the mechanism for tensioning the lifting ropes 2, 2' is not limited to the previous example. For example, the pulley mounting frame 19 may be constantly pulled downward by a spring, but the mechanism for tensioning the lifting ropes 2, 2' is not limited to the above. such as applying tension to
Optional.

The conventional groove-shaped guide rail described above merely guides the descent of the bottom par that descends under its own weight and prevents large swings, and rattling due to vertical movement is unavoidable. , 2' have various functions such as raising and lowering the blind, guiding it, stopping it from swinging, and receiving it.

The slat 15 is, for example, an airfoil-shaped curved plate made of aluminum or stainless steel with a thickness of 0.5 to Q and about 8 mm, and is provided near both left and right ends so that the filaments 2a are loosely fitted therein.

For example, the elevation angle of the slat 15 can be adjusted using an angle gear 16.
The operation of moving the ladder tape 17 up and down by operating is the same as in the conventional one.

The lower end of the ladder tape 17 is received by a ladder tape receiving pulley 18 fixed within the bottom par 13.

In this way, the slats 15 are connected to the bottom par 13 and the lifting ropes 2, 2', allowing the blind 1 to extend freely, and when the blind is in the unfolded state, the ladder tape 17 is stretched. This prevents shaking and flapping.

As described above, the present invention is such that the lifting ropes 2, 2' are installed under tension and the bottom par 13 is fixed to the ropes, so it is resistant to wind swaying and stirring and is ideal as an outdoor blind. This mechanism forcibly moves the bottom par (and therefore the slats) up and down (i.e., the unfolding line holder) by driving the lifting rope, so it can be installed on slopes and ceilings, which are impossible to install with conventional Venetian blinds. Therefore, it is possible to provide an excellent Venetian blind in which the intermediate portion of the unfolded blind does not sag and the unfolding wire receiving operation can be performed freely and reliably.
