The curtain used in the present invention can be manually operated or electrically operated. Please refer to the first to third figures. The curtain 10 provided by the first preferred embodiment of the present invention is an electric curtain, comprising: an upper rail 20; A driving device 30, at least one roping device 40, two fabrics, a middle rail 60, a bottom rail 65, and a long pull cord 70 and a short pull cord 75 equal to the rope reeling device. This specification discloses a preferred embodiment of the present invention. All the components can be appropriately changed without departing from the spirit of the invention, and are not limited to the description.

The upper rail 20 is a hollow elongated body having a single cross section. The upper rail, the middle rail 60 and the bottom rail 65 are arranged from top to bottom with the upper rail being the highest and the bottom rail being the lowest.

The driving device 30 includes a transmission rod 32. The transmission rod 32 is disposed in the upper rail 20, and the two ends are respectively disposed at the end caps 22 at both ends of the upper rail 20 and are rotatable. Since the present embodiment is an electric curtain, the transmission rod 32 is an electric transmission rod, and an electric driving mechanism (not shown) is disposed inside to drive the transmission rod 32 to rotate. The electric drive unit is a conventional component and will not be described.

Referring to the fourth figure, the embodiment has at least two reeling devices 40, each of which has a two-rope group 42, which is a long rope reel set 42A and a short rope reel set 42B, each roll. The rope set 42 has a rope shaft 44 and a rope base 46. The rope base 46 is fixed in the upper rail 20. The rope shaft 44 is pivotally mounted on the rope base 46 and sleeved thereon. The outer circumference of the transmission rod 32 enables the transmission rod to drive the rope shafts 46 to rotate.

This embodiment has a first and a second fabric, the first fabric being a light-tight cloth 50, and the second fabric being a light-transmitting yarn 55. The top end of the cloth 50 is connected to the middle rail 60, and the bottom end is connected to the bottom rail 65. The top end of the yarn 55 is connected to the upper rail 20, and the bottom end is connected to the middle rail 60. The second cloth can be of various shapes and is not limited to the honeycomb shape of the figure.

In detail, the middle rail 60 and the bottom rail 65 are extruded bodies; the top end and the bottom end of the cloth 50 are respectively engaged with the bottom end of the middle rail 60 and the top end of the bottom rail 65 by a panel 51; The bottom end of the yarn 55 is embedded on the top end of the middle rail 60 by a panel 56 (as shown in the third figure), and the top end thereof may be directly connected to the upper rail 20, or may be connected to the upper rail 20 by an insert or an elongated frame 58. On the rail.

Each long drawstring 70 and each short drawstring 75 are coupled with a rope reeling device 40. Referring to the seventh figure, the head end of the short pull cord 75 is connected to the rope shaft 44B of the lanyard rope set 42B, and the end thereof passes through the upper rail 20 and is connected to the middle rail 60. The end of the long cable 70 is connected to the rope shaft 44A of the long rope assembly 42A, and the end thereof passes downward through the middle rail 60, and after winding the bottom rail 65, then goes up again. The middle rail 60 is connected. As can be seen from the seventh figure, the ends of the long and short drawstrings 70, 75 are substantially connected to the middle rail 60 to form a loop.

In the present invention, the length (release length) of the long drawstring 70 is twice or more than that of the short pull cord 75. Taking the twelfth figure as an example, when the short drawstring 75 is completely released, its vertical length (upper rail to middle rail) is L, and the long drawstring 70 has a vertical length of 2L. Therefore, in the twelfth figure, the long drawstring 70 is laid down halfway in length, and the other half length is still wound on the long rope take-up reel shaft 44A.

In addition, referring to the fifth figure, in practice, after the end of the two drawstrings 70, 75 is penetrated into the middle rail 60, the through holes 63 of the end cover 62 at one end of the middle rail pass through, and knot N or one. The clip is fixed such that the ends of the two drawstrings are positioned on the outer wall of the end cap 62. Thereby, the assembly personnel can conveniently adjust the vertical length of the two drawstrings, and the length of the drape of the fabric can be adjusted according to the size of the window.

Referring to the sixth figure, in order to reduce the frictional force when the long drawstring 70 and the bottom rail 65 are relatively slipped, the bottom rail is provided with at least one roller set 66 (two sets in this embodiment) for the long drawstring to be wound. . Each roller set 66 has a roller seat 67 and at least one roller 68 mounted in the roller seat. The roller seat 67 can be fixed to the inner wall surface of the bottom rail 65 or fixed to the bottom end of the cloth 50 and located in the bottom rail. The long drawstring 70 is wound around the roller 68 of the two roller set 66 to achieve a piercing structure with the bottom rail.

It should be noted that the long drawstring 70 and the bottom rail 65 are not connected to the bottom rail by the long drawstring, and the roller set 66 can be fixed to the bottom as shown in FIG. The outer wall of the rail 65 allows the long drawstring to be penetrated into the bottom rail without being inserted into the bottom rail.

The manner in which the window covering 10 is used will be described below. The schematic diagrams of the eighth and ninth figures show that the window covering 10 is fully open, that is, the two fabrics 50, 55 are completely folded. At this time, the two drawstrings 70, 75 are completely retracted by the two reel shafts 44A, 44B, respectively, and the two drawstrings are wound by the take-up reel in the same take-up direction.

When the curtain is to be lowered, the power supply is cut so that the transmission rod 32 drives the two reel shafts 44A, 44B to rotate in the forward direction, that is, the counterclockwise rotation of the tenth and eleventh figures, and the two ropes 70 and 75 are suspended together. Therefore, the middle rail 60 and the bottom rail 65 are descended synchronously, and the second fabric (the yarn 55) is deployed; at this time, the middle rail 60 and the bottom rail 65 are not displaced relative to each other, the first fabric (the cloth) 50) Still in a collapsed state. The tenth and eleventh figures show that the curtain is half-open, and the yarn 50 can transmit light.

The drive rod 32 and the two reel shafts 44A, 44B continue to rotate in the forward direction, and the two pull cords 70, 75 can be continuously released. The twelfth and thirteenth figures show that the curtain is lowered to the maximum length. At this time, the short drawstring 75 is completely suspended from the short rope reel shaft 44B, and the yarn 55 completely shields the window, and the curtain 10 is light transmissive. Shading.

Since the short pull cord 75 is completely lowered in the state of the twelfth and thirteenth drawings, when the transmission rod 32 continues to rotate forward, the short rope rotary shaft 44B is forwardly rotated, but is reversely The short drawstring 75 is wound up as shown in Figures 14 and 15, while the long rope reel shaft 44A continues to release the long drawstring 70 in the forward direction. In this operating state, although the transmission rod 32 maintains the same steering (counterclockwise forward rotation), the two cables 70, 75 are wound in different directions, so the two cables 70, 75 form a In the actuating circuit, the short drawstring 75 is taken up, and the long drawstring 70 is in the payout line, and the long drawstring is slid relative to the bottom rail 65. During the operation of the two drawstrings, the bottom rails 65 are maintained at the same height and do not rise or fall. As the short pull cord 75 is retracted and the long pull cord 70 is released, the middle rail 60 is pulled up by the short pull cord 75, the cloth 50 is unfolded upward, and the yarn 55 is gradually moved from the bottom end to the bottom. On the fold. In this state of use, the window is partially yarn 55 and a portion of the cloth 50 The cloth 50 is shielded from light, and the yarn 55 is transparent.

When the transmission rod 32 continues to rotate forward, as shown in the sixteenth and seventeenth, the short rope reel shaft 44B completely retracts the short rope 75, and the long rope reel shaft 44A carries the long rope 70. Released, at this time, the middle rail 60 is moved up to the highest point and has the longest distance from the bottom rail 65; the yarn 55 is completely folded, and the cloth 50 is fully deployed, so that the curtain 10 is formed. Completely shaded.

In the full shading state of the sixteenth and seventeenth views, the transmission rod 32 is reversed, so that the two pull cords 70, 75 and the second fabric can be reversely operated. In short, the long drawstring 70 is retracted by the long rope reel shaft 44A, and the short drawstring 75 is released by the short rope reel shaft 44B, so that the middle rail 60 is gradually moved downward, and the yarn 55 is gradually lowered. Expand, and the cloth 50 gradually folds down. When the state shown in the fourteenth and fifteenth figures is reached, the short pull cord 75 is completely released, and that the long drawstring 70 has a half or more of the vertical length which is taken up by the long rope reel shaft 44A. The middle rail 60 is moved down to the lowest position so that the cloth 50 is completely folded and the yarn 55 is fully deployed. Thereafter, when the transmission rod 32 continues to reverse, the lanyard rope shaft 44B is converted into a winding short rope 75. At this time, the two rope shafts 44A, 44B are wound together in the same winding direction. The ropes 70, 75 simultaneously drive the middle rail 60 and the bottom rail 65 to move up, and gradually fold the yarn 55, and finally the yarn is completely folded, and the curtain 10 returns to the full state of the eighth and ninth figures.

In this embodiment, the electric curtain is driven by the electric power to drive the transmission rod 32 to rotate, and the curtain is positioned with a power-off design, that is, when the cloth is rolled to the full shading state of the eighth figure or the full shading state of the sixteenth figure. , will automatically power off, so that the drive rod no longer rotates.

It can be seen from the above description that the curtain 10 of the embodiment can control the two fabrics 50 and 55 only by a single manipulation device (ie, the driving device) to change different shading effects, and the curtain can be fully opened, half opened, fully closed, The yarn is completely uncovered, and the cloth is completely shielded from light, or the yarn and the cloth are simultaneously unfolded to block light.

The eighteenth and nineteenth drawings are the second preferred embodiment of the curtain 10' of the present invention. Most of the components of the present embodiment can correspond to the components of the first embodiment, and the corresponding components follow the same component symbols. Do not repeat them.

The window covering 10' also includes an upper rail 20, a driving device 30, a plurality of rope reeling devices 40, a middle rail 60, a bottom rail 65, and a long drawstring 70 and a short drawstring equal to the rope reeling device. 75. The driving device 30 is manually operated, and has a transmission rod 32 and a driving mechanism 34, which is a bead mechanism. The long rope rolling shaft 44A and the short rope rolling shaft 44B of each rope reeling device 40 are sleeved on the outer circumference of the transmission rod 32, and the bead 35 of the driving mechanism 34 is pulled to drive the transmission rod 32 and the ropes. The shafts 44 rotate together to retract or release the drawstrings 70,75.

In this embodiment, only the first fabric 50 is provided, and there is no second fabric. The curtain 10' of the embodiment is taken as an example of a roman shade. The top and bottom ends of the fabric 50 are respectively connected to the middle rail. 60 and bottom rail 65. The long and short drawstrings 70, 75 are connected in the same manner as the previous embodiment. The end of the short pull cord 75 is connected to the middle rail 60, and the end of the long drawstring 70 is wound around the roller 68 of the bottom rail 65. The middle rail 60. The ends of the two drawstrings can be positioned at the end caps at one end of the middle rail as in the first embodiment.

The schematic view of Fig. 20 shows that the window covering 10' is fully open, the fabric 50 is completely folded, and the two ropes 70, 75 are completely retracted by the two rope shafts 44A, 44B.

When the transmission rod 32 drives the two rope shafts 44A, 44B to rotate in the forward direction, the two ropes 70, 75 are suspended together, and the middle rail 60 and the bottom rail 65 are simultaneously lowered, and the related operations can be referred to the tenth and tenth. A description of the picture. At this time, the middle rail 60 and the bottom rail 65 are not displaced relative to each other, and the fabric 50 remains in the folded state.

As the two drawstrings 70, 75 continue to release, when the short drawstring 75 is fully released, the middle rail 60 and the bottom rail 65 are lowered to the lowest height, as shown in the twenty-first figure, the relevant action can be referred to the twelfth The description of the thirteenth figure. At this point, the fabric 50 is lowered to the window. At the lowest point of the curtain 10', the entire curtain 10' is hollowed out.

When the transmission rod 32 continues to rotate forward, the long drawstring 70 continues to be lowered, and the short drawstring 75 is reversely wound by the short rope rotary shaft 44B, and the two drawstrings form a loop for receiving and discharging. When the middle rail 60 is moved up, the fabric 50 is gradually unfolded upward, and is shielded from bottom to top. As shown in FIG. 19, the related operations can be explained in the fourteenth to seventeenth drawings. The fabric 50 can eventually be fully deployed, as shown in Figure 22, completely obscuring the window.

The window covering 10' provided in this embodiment has a use form of hollowing out, in addition to the full-opening, full-closed and semi-shielded use forms, as shown in the twenty-first figure, providing an unprecedented use effect.

In summary, the present invention provides an innovative design for the curtains, and has many practical effects, and is applied according to law.
