Description

Curtain

This creation relates to an improvement of curtains, in particular to a curtain design that can make the curtain blades rise and fall more smoothly and with lower production costs.

The composition of traditional curtains is mainly based on a U-track as the main frame, and a curtain control angle tube, a rope positioner and a shaft controller are respectively set in the concave space of the U-shaped track; the curtain control The corner tube must rely on a fixing frame to fix the curtain sheet control corner tube in the concave space of the U-shaped track. The curtain sheet controls the upper end of the corner tube and fixes two ladder belts, extending downward to connect each blade, while the curtain sheet controls the upper end of the corner tube and fixes two ladder belts. There is another shaft through the center of the angle cylinder, which is connected to the shaft controller. The shaft controller controls the rotation of the shaft to drive the curtain sheet to control the rotation of the angle cylinder, so that the ladder belt controls the opening or closing of the blade; it is used to control the release and release of the blade. For folding, the drawstrings fixed on both sides of the hem are made by using the drawstring positioner, and the drawstring positioner is passed through and then extended downward for the user to pull the drawstring to control the folding or releasing of the blades.

It can be seen from the above explanation that the U-shaped track must be cut and punched by a machine during the production and processing of traditional curtains. The production and processing process is quite complicated and requires professionals. Secondly, because traditional curtains have many accessories, in addition to occupying In addition to the space, it must take a long time to assemble, and the production cost is also greatly increased due to the large number of accessories.

Furthermore, the traditional curtains are arranged in the drawstring, and the method adopted is that the drawstring is wound around the drawstring. The rollers are then extended downward and fixed at more than two positions of the hem, and the lengths of the ropes above these two positions are different, and the pulling force they bear is also different. Therefore, when the hem is pulled up, more than two positions Because of the different strength, it will cause the hem to be unbalanced, which is quite unstable.

The reason is that the creators have studied and improved the existing curtains in view of this, and provided a curtain design with low cost and can keep the blades rising and falling smoothly, in order to achieve the purpose of better practical value.

The purpose of this creation is to provide an improvement, using the control shaft tube and the rope winding shaft tube sleeved with more than two rope drums, and the pull rope is guided through the inclined surface of the rope drum, and sequentially surrounds the cone of the rope drum. The shape of the cylinder body, and then the design of the different displacements of each rope reel, produces the effect of mutual restraint, so that the pull rope will keep the positioning without deviation, and the blade will be more stable up and down.

In order to achieve the above purpose, the present creation discloses a curtain, comprising:

A control shaft tube is a hollow tube body, the upper and lower ends of the tube body are provided with positioning grooves, two ladder belts with collars on the outer edges are laid on both sides of the positioning groove, and fixed to the two sides of the control shaft tube with positioning pieces The sides extend downward to connect the sides of the blades without punching holes, and control the opening or closing of the blades.

A rope reeling shaft tube, which is a hollow tube body, with positioning grooves at the upper and lower ends. The tube body is sleeved with one or more rope reeling cylinders that can move and slide the tube body. The rope reeling cylinder is a hollow cylinder body, and the cylinder body is a The tapered structure of the inclined surface has a driving body protruding from the inner surface of the hollow cylinder, which is matched with the positioning groove of the winding shaft tube, and is driven by the rotation of the winding shaft tube to make the winding tube rotate accordingly.

The outer edge of the rope reeling drum is formed with two retaining walls to define the surrounding area of the pulling rope. The two retaining walls are also provided with perforations for the head end of the pulling rope to be threaded and then tied with a knot to fix the head end of the rope.

A ladder belt group, including two or more ladder belts, the ladder belts are arranged across the control shaft There are several collars on the outer edge of the tube, and the top of the ladder belt is fixed with a fixing piece, so that the two ladder belts are hung down from both sides of the control shaft tube and positioned in the middle of the rope drum respectively, and then connected to each blade. Controls the opening or closing of the blades.

A pull rope group, including more than three pull ropes, the three pull ropes are the perforations for fixing the head ends of the pull ropes to the wider structure of the rope drum, and the pull ropes on the left and right sides are connected to the rear side of the blade, The middle pull rope is located at the corresponding front end, and the three pull ropes are wound around the rope drum in the same direction, and the left and right movement of the rope drum is used to slide, so that the winding of the three pull ropes produces a restraining effect, and the upper and lower blades are more smooth.

Regarding the technical core of this creation, the ladder is positioned at the position of the narrower diameter of the tapered structure of the rope drum body to form a symmetrical suspension, and the head end of the rope is connected to the tapered structure of the rope drum body with a wider diameter. The position of the diameter, and the position corresponding to the narrower diameter is set with a positioning piece, so that the displacement of the rope reel can only move in the direction of the wider diameter, so that the displacement force of the rope reel is exactly the same as that of the pull rope due to the blade. The pulling force of gravity is equal, so that the pull rope will be neatly wound along the cone-shaped structure of the rope drum, so that the pull rope will not sway arbitrarily, and the folding or releasing of the blades is more stable.

Compared with traditional curtains, the beneficial effects of this creation:

1. The structure of this creation is simple, and the installation and disassembly are easy and convenient. During the production and processing process, anyone can directly produce it without purchasing any machine, and the volume becomes smaller and does not occupy space.

2. The reeling shaft tube of this creation can be used and installed for ropeless controllers, electric motor controllers, bead chain controllers and labor-saving spring controllers, which increases the scope of use and reduces the manufacturing cost.

3. This creation uses a fixed piece to fix the ladder belt, and the positioning piece is used to limit the displacement of the rope reel in one direction, so that the rope is wound neatly along the rope reel, and the length of each rope is the same, and the tensile force it bears is also the same. The blade will not sway arbitrarily, improving the stability of the blade.

4. In this creation, the control rope is no longer used to control the up and down of the blade. In particular, the control shaft tube is used to control the opening or closing of the blade, and the opening or closing of the blade is controlled through the rope drum of the rope winding shaft tube. There is no control rope exposed at all. On the side of the curtain, it can prevent children from playing with the control rope and wrap it around the neck, preventing the occurrence of danger, improving safety, and complying with the regulation of no rope.

5. This creation uses the pull rope to be evenly connected to both sides of the blade without punching holes, which is convenient and simple to install. It can be operated and installed without professionals, and the shading degree of the blade can be improved.
