Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a fold-up type curtain that is applied to a sloped window such as the ceiling of a sunroom.

[Conventional technology]

Generally, this type of pull-up curtain has a drum rotated by an operating cord at the top of the slanted window, and a curtain cloth (hereinafter simply referred to as raw cloth) is attached to the lower end of the lifting cord that is wound and unwound on this drum. ) Connect the weight bar at the lower end and fold up the raw cloth when the lifting cord is wound around the drum.
Also, when the lifting cord is unwound from the drum, the cloth is spread out.

However, the situation when opening and closing the curtains is
This varies depending on the individual user, and if the operating cord is pulled or loosened extremely quickly, the lifting cord will not be smoothly wound onto or unwound from the drum. In some cases, the phenomenon of entanglement such as reverse winding appeared.

[Problems to be solved]

The present invention has been made with the purpose of providing a pull-up curtain for inclined windows in which the lifting cord is always properly wound up and unwound on the drum, regardless of the operating conditions. be.

[Means to solve problems]

The features of the lift-up curtain of the present invention, which was made to achieve the above object, are that a stopper is provided at the lower end of the lifting cord to prevent the lifting cord from coming out of the guide hole, and a weight is provided at the lower end of the lifting cord. The lifting cord is connected to the drum so that the movement of the lifting cord can be maintained in a tensioned state more smoothly than the movement of the weight bar, thereby eliminating the entanglement of the lifting cord with the drum.

The stopper provided on the lifting cord is a locking part that determines the lowering limit of the weight bar.For example, the lifting cord is inserted into the guide hole of the weight bar, and the lower end of the lifting cord is inserted through the hole. However, since a weight is connected to the lower end of the lifting cord, if this weight is used as a stopper, there is an advantage that there is no waste in the structure.

[Example of idea]

FIG. 1 shows an outline of an embodiment of the present invention. Reference numeral 1 denotes a drum disposed on the upper end side of a tilted window (not shown), and is rotated in forward and reverse directions by an operating cord 2. Reference numeral 3 denotes a raw curtain cloth, whose upper end is fixed near the drum, and guide lines 4 provided at appropriate intervals and a weight bar 5 at the lower end of the raw cloth are raised and lowered by guide rails 6 (shown in FIG. 2). It is spread out or folded up as it is done.

Reference numeral 7 denotes a lifting cord, the upper end of which is connected to the drum 1 so as to be wound and unwound, and the lower end thereof is connected to a U as a guide hole provided in the weight bar 5.
The pin 8 is inserted through the hole and a weight 9 is connected to the lower end.

According to this configuration, when the curtain is folded up, the weight 9 lifts the weight bar 5 upward along the guide rail 6 by winding the lifting cord 7 onto the drum 1, and on the other hand, when the curtain is unfolded, the weight bar 5 is lifted up and down. By unwinding the cord 7 from the drum 1, the weight bar 5 is allowed to descend due to its own weight, and the raw cloth 3
will be expanded.

Furthermore, if the unwinding of the lifting cord 7 from the drum 1 is extremely fast and the loosening of the lifting cord 7 is faster than the lowering of the weight bar 5 due to its own weight, the lifting cord 7 will be unwound from the weight 9. The cord itself moves as shown by the chain line in Figure 2, and after this,
The weight bar 5 will now be lowered.

In other words, the lifting cord 7 is always maintained in a taut state, thereby providing the effect that the lifting cord 7 will not become tangled with the drum due to loosening.

[Effect of idea]

As mentioned above, the pull-up curtain for slanted windows according to the present invention has the effect that the tension of the lifting cord is always maintained and does not become entangled with the drum, and its practical benefits are as follows. It is a big thing.
