Description

curtain puller

The present invention relates to a cordless curtain structure, in particular to a curtain pulling device capable of double-opening up and down to adjust the light.

According to a conventional curtain structure, such as a curtain that can be automatically raised in the National Patent Publication No. I229717, it includes: a frame, and a first pulley, a second pulley, a first guide wheel and a second guide wheel are arranged in the frame. A wheel, a shielding object is arranged at the bottom end of the frame, and a bottom frame is arranged at the bottom end of the shielding object; a control device has a combination frame and is arranged in the frame, the combination box forms an accommodating space, and a first wire wheel is pivoted in the accommodating space And the second wire wheel, the first wire wheel and the second wire wheel have shaft tubes with perforated inside, the two ends of the shaft tubes are formed with an upper sealing plate and a lower sealing plate, and a middle partition plate is formed on the shaft tube to separate the shaft tube area. The upper side is a wire groove, and the lower side is a ring groove. The wire grooves of the first wire wheel and the second wire wheel are wound with ropes. The ropes are double-row lines with two lines side by side. The ropes pass through the combination frame and are wound around. After passing through the first pulley, the first guide pulley, the second pulley, and the second pulley, any line of the double-column wire can pass through the first pulley and the second pulley, and pass through the frame downward and pass through. The shielding object and the bottom frame, and any end of the wire is fixed to the bottom end of the bottom frame with a fixing piece; a reversible spring, which forms an S shape, and has a first coil part and a second coil part that can be surrounded, and the first coil part is positioned It is wound in the annular groove of the first wire wheel, and the second coil portion is positioned and wound in the annular groove of the second wire wheel. With this design, when you want to fold up or unfold the shading object, you just need to push up the bottom frame or pull down the bottom frame by hand, thus forming a curtain structure with no drawstring, labor-saving operation and can be positioned at any height. .

Looking at the above-mentioned conventional structure, it is not difficult to find that there are still some deficiencies. The main reasons are as follows: The conventional curtain structure uses the push-up and pull-down actions of the bottom frame to perform the effect of folding and unfolding the shielding object, although it can be The shading object can be adjusted and positioned at any height by means of no drawstring, but the dimming method of the shading object with only one direction is still too monotonous, lacking in variability and practicability, and there is still a need for improvement.

Next, a horizontal rib 122 is protruded on both sides of the top opening 12 of the upper rail 10 , and the rail 121 is set with the horizontal rib 122 as a reference plane, and a vertical rib is provided downward on the bottom surface of the two horizontal ribs 122 Plate 123, the bottom surface of the groove chamber 11 is provided with two vertical ribs 124 corresponding to the two vertical ribs 123, and the predetermined positions on both sides of the bottom surface of the groove chamber 11 are symmetrically provided with two non-circular hole-shaped positioning holes 113; The pulley seat 20 is provided with stepped engaging portions 215 on the outer side of the top ends of the vertical plates 211 of each bracket group 21, and the two horizontal ribs of the upper rail 10 are passed through the engaging portions 215. The plate 122 is slidably assembled into the groove chamber 11, and the bottom surface of the pulley seat 20 is provided with a non-cylindrical positioning protrusion 216, and the positioning protrusion 216 and the bottom surface of the groove chamber 11 are used for positioning The hole 113 is inserted and positioned; the rope reel 30 is mounted on a base 301 to install the first and second reels 31 and 32, and the base 301 Two upright limiting ribs 302 are provided on both sides of the upper and lower end surfaces, the base is straddling above the vertical rib 124 of the groove chamber 11, and the two limiting ribs 302 on the lower end surface Slide and assemble along the outer sides of the two vertical ribs 124, and the limiting ribs 302 on the upper end surface of the base 301 are relatively snapped on the outer sides of the two vertical ribs 123, thereby completing the installation of the rope reel 30, and Respectively abutting one end of the pulley seat 20 to restrict positioning, the pulley seat 20 and the rope reel 30 can be assembled and fixed in the groove chamber without tools by the above assembling method.

For the actual use state of its structure, please refer to Figure 4 and Figures 6 and 7. When the curtain of this creation is fully folded and concentrated, the top rod 41 of the curtain body 40 is pushed up against the upper rail 10. and the bottom rod 42 squeezes the curtain 43 upward and clamps it on the bottom of the top rod 41. On the other hand, the two rope reels 30 in the upper rail 10 pass through the first reel 31. The first and second pulling ropes 34 and 36 are rolled up and collected, and the elastic piece 33 is tied to the second winding wheel 32 to form a rolled state and has not been released. Therefore, when the bottom rod 42 of the curtain body 40 pulls down , the second cord 37 will be stretched and the second pull cord 36 will be pulled out from a first reel 31 of the cord reel 30, and the first reel 31 will be rolled and wound synchronously The elastic piece 33 is released, and the sagging weight of the bottom rod 42 is used to balance the positioning of the elastic piece 33 to achieve the purpose of pulling and stopping without a rope, so that the curtain 43 is pulled down and unfolded to form a shading effect; When the top rod 41 of 40 pulls down, the first curtain cord 35 is pulled and the first pull cord 34 is pulled out from the first reel 31 of the other cord reel 30, and the first roll is simultaneously rolled The pulley 31 is wound to release the elastic piece 33, and then the sagging weight of the ejector rod 41 is used to balance and position the elastic piece 33, so as to achieve the purpose of pulling and stopping without a rope, so that the ejector rod 41 is pulled down away from the bottom of the upper rail 10. And compress the upper half of the curtain 43 to form the light entering effect of the upper half of the curtain; accordingly, the curtain can operate the bottom rod 42 and the top rod 41 respectively, so as to adjust the shading range of the lower half of the curtain 43 Or the light entry range of the upper half.

In addition, when the top rod 41 or the bottom rod 42 is pushed up, the top rod 41 or the bottom rod 42 is pushed upward. The drooping force of the bottom rod 42 disappears, the elastic piece 33 loses its balance weight and rewinds and resets, and drives the first reel 31 to reversely roll and collect the first pull rope 34 or the second pull rope 36 and then retract the first curtain cord 35 or the second curtain cord 37 to fold and position the top rod 41 or the bottom rod 42 upward, so as to achieve the purpose of folded and concentrated the curtain body 40 .

With the structure of the above-mentioned specific embodiment, the following benefits can be obtained: the pulley base 20 is provided with upper and lower pulleys 22, 23, and through the upper and lower pulleys 22, 23 the first curtain cord 35 and the The circuitous winding of the second curtain cords 37 enables the first and second curtain cords 35 and 37 to be separated to maintain an appropriate distance, avoiding mutual shuttling and winding and knotting, and ensuring the traction of the first and second curtain cords 35 and 37 For the stability, the first and second curtain cords 35 and 37 are connected with the top rod 41 and the bottom rod 42 of the curtain body 40 to achieve the effect of two-way adjustment of the curtain body 40, making the curtain more variable in use. , which helps to improve the practicability of the curtain.

To sum up, the present invention has indeed achieved a breakthrough structural design, and has an improved content of the invention, and at the same time can achieve industrial applicability and progress, and the present invention has not been found in any publications, and it is also novel.
