Abstract
Description
- The invention relates to a roller blind, in particular to an upper F free opening and closing coil with more reliable operation curtain.
- Roll-up curtains are easy to use, beautiful and generous, and are widely used in home life and office places. The commonly used method of existing roller blinds is to fix and install the roller on the upper end of the window, rotate the roller, and wind or release the curtain. This kind of curtain is first opened from the lower part of the window, so that the upper part of the window is shaded, and the lower part is lighted. When opened, the lower part of the window cannot block the line of sight, and the upper part cannot light.
- In real life, private spaces such as rooms, reception rooms, bathrooms, school classrooms, and some office spaces often require the lower part of the window to block the line of sight, while the upper part of the window is used for daylighting. This requires a top-opening roller blind. In order to block the line of sight or direct light in different parts, sometimes it is necessary to block the middle or upper part of the window. The ideal function of the roller blind is to open any size at any position.

Among them, 1 is a movable pulley, 2 is a curtain, 31 is a lifting section, 32 is a pull-down section, 33 and 34 are connecting sections, 41, 42, 43, 44 are winders, and 51, 52, 53, 54 are tensioners Wheel, 6 is the counterweight, 7 is the intermediate gear, 8 is the guide groove, 91 and 92 are the motors, 10 is the controller, 11 is the drive shaft, 12 is the fixed gear seat, 61, 62, 63, 64 are the bead chains. - As shown in
Figure 1 , a vertical free opening and closing roller blind, including a reel (not shown in the figure), amovable pulley 1, a traction rope and acurtain cloth 2. The upper end of thecurtain cloth 2 is fixed on the reel, and the lower end is a free end, which is provided with a Heavy 6. - The traction rope of the present invention includes an
upper lifting section 31 and a pull-down section 32. The two ends of theupper lifting section 31 are connected to the winder 41 and the winder 42, and the two ends of the pull-down section are connected to thewinder 43 and the winder 44. Thelifting section 31 is stretched upwards after bypassing themovable pulley 1, and the pull-downsection 32 tensions the movable pulley downwards, so that themovable pulley 1 remains stable at all times. - When the
bobbin 42 and thebobbin 44 are stationary, thebobbin 41 is released and thebobbin 43 is wound, the winding shaft moves downward while winding up the curtain, achieving the effect of opening the curtain up. When thebobbin 42 and thebobbin 44 are stationary, thebobbin 41 is wound and thebobbin 43 is released, the winding shaft moves upward while releasing the curtain, achieving the effect of closing the curtain upward. - When the
bobbin 41 and thebobbin 42 are wound at the same time and thebobbin 43 and thebobbin 44 are released at the same time, the reel and the cord as a whole rise; when thebobbin 41 and thebobbin 42 are released at the same time, thebobbin 43 When winding with 44 at the same time, the reel and the curtain are lowered as a whole, so that it can be covered at any position of the window. - As shown in
Figure 2 , a freely opening and closing roller blind includes a reel (not shown in the figure), amovable pulley 1 and acurtain 2. The traction rope includes anupper lifting section 31 and a loweringsection 32, which are connected by connectingsections tensioning wheel 51 and thetensioning wheel 52 are traction wheels. They can be driven manually or by a motor. The traction rope can be a variety of wires with small elongation, or a bead chain, or a timing belt can be selected. Of course, the tensioner and the movable pulley also need to choose a structure that matches the traction rope. When the traction rope is a bead chain, the tensioner and the movable pulley are sprockets; when the traction rope is a timing belt, the tensioner and the movable pulley are the timing pulleys. - The
lifting section 31 of the traction rope bypasses themovable pulley 1 and is tensioned upward, and the pull-downsection 32 bypasses themovable pulley 2 and is tensioned downward to keep themovable pulley 1 stable. The upper end of thecurtain fabric 2 is fixed on the reel, and the lower end is provided with acounterweight 6. - As shown in
FIG. 3 , themovable pulley 1, the traction rope and the tensioning wheel are provided with aguide groove 8, thetensioning wheel 52 is provided with anintermediate gear 7, and theguide groove 8 is provided with a fixedgear seat 12 that can mesh with theintermediate gear 7. Thetension wheel 51 and thetension wheel 52 are provided with a coaxial ring gear, and theintermediate gear 7 always meshes with the ring gear on thetension wheel 52. When thetensioning wheel 52 needs to be rotated, as shown inFigure 4 , theintermediate gear 7 is rotated around the axis of thetensioning wheel 52 so that it meshes with the ring gear on thetensioning wheel 51, and thetensioning wheel 51 drives the tensioning wheel. Thepinch wheel 52 rotates. - As shown in
Figures 3 and4 , the way theupper pull section 31 is wound around thetensioning wheel 52 is different from the way used inFigure 2 . This connection mode can be linked to thetensioning wheel 51 and thetensioning wheel 52 through theintermediary gear 7 to achieve traction. The two ends of therope lifting section 31 move upward or downward simultaneously. - By driving the
tensioning wheel 51 manually or by a motor, and engaging or disengaging theintermediate gear 7, the combined actions of the two traction wheels of rotation, stationary and different rotation directions can be realized as follows:
When thetensioning wheel 51 rotates clockwise, theintermediate gear 7 remains disengaged from the ring gear on thetensioning wheel 51, and meshes with the fixedgear seat 12, so that thetensioning wheel 52 is stationary. Due to the traction of thetensioning wheel 51, the lifting Thesection 31 is gradually extended, and the pull-downsection 32 is gradually shortened. The traction rope drives thepulley 1 to descend and rotates counterclockwise at the same time. The curtain is rolled up, and the roller blind is opened from top to bottom to achieve the top-opening effect. - When the
tensioning wheel 51 rotates counterclockwise, theintermediate gear 7 remains disengaged from the ring gear on thetensioning wheel 51, and meshes with the fixedgear seat 12, so that thetensioning wheel 52 is stationary. Due to the traction of thetensioning wheel 51, the lifting Thesection 31 is gradually shortened, and the pull-downsection 32 is gradually extended. The traction rope drives thepulley 1 to rise and rotate clockwise at the same time, and the curtain is released, thereby achieving the effect of closing the roller blind from bottom to top. - When the
tension wheel 51 rotates counterclockwise, theintermediate gear 7 disengages from the fixedgear seat 12 and meshes with the ring gear on thetension wheel 51, and thetension wheel 52 also rotates counterclockwise, as shown inFIG. 4 . Since the traction rope is wound on thetension pulley 52 in the reverse direction, both ends of theupper lifting section 31 of the traction rope are shortened at the same time. Otherwise, the curtain will be lowered as a whole, so as to achieve the effect of sheltering at any position of the window. - As shown in
Figure 5 , the arrangement of the reel (not shown in the figure), theguide groove 8, themovable pulley 1, thecurtain 2, the traction rope and the fixed pulley is the same as that of the second embodiment, without the intermediate gear and the fixed gear seat. Thetensioner 51 and thetensioner 52 are respectively driven by themotor 91 and themotor 92, themotor 91 and themotor 92 are controlled by thecontroller 10, through thecontroller 10, various programs can be set to control the rotation and the stationary of themotor 91 and themotor 92 respectively. And different rotation directions, so that the two traction wheels can achieve the combined action as described inEmbodiment 2, so that the curtain can achieve the effect of opening or closing or covering any position of the window. - By making the diameter of the movable pulley and the reel the same or similar, it can be ensured that when the curtain is opened or retracted, the bottom end of the curtain always keeps up and down or does not move up and down obviously.
- As shown in
FIG. 6 , guidegrooves 8 are provided on both sides of the roller blind, and the traction rope, themovable pulley 1 and the tensioning wheel are all installed on theguide groove 8. The traction ropes, tensioning wheels, and movable pulleys on both sides of the roller blind are arranged symmetrically, and the reel is arranged between the twomovable pulleys 1, and a curtain cloth is wound on it. In order to realize the synchronous movement, the traction wheels on both sides are coaxially connected by thedrive shaft 11, so that the synchronous movement of the movable pulleys on both sides can be realized only by driving the traction wheels on one side. - Connecting the two ends of the
counterweight 6 at the lower end of thecurtain fabric 2 to the corresponding positions of the pull-down section of the traction rope will not affect the retracting and overall lifting of the curtain fabric. Therefore, the up and down freely opening and closing roller blind of the present invention can be applied to inclined or horizontal installation. - As shown in
Fig. 7 , thetension wheel 51 and thetension wheel 52 are independently manually driven by a set of bead chain-sprocket wheels. The closed loop bead chain that drives thetensioning wheel 52 freely sags into twosections tensioning wheel 51 freely sags into two sections, 63 and 64. - Pull down 61, the
tension wheel 51 rotates counterclockwise, thetension wheel 52 is stationary, the traction rope drives thepulley 1 to rise and rotate clockwise at the same time, the curtain is released, thereby achieving the effect of closing the roller blind from bottom to top. On the contrary, if 62 is pulled downwards, the traction rope drives thepulley 1 to descend and rotates counterclockwise at the same time, and the curtain is rolled up, thereby realizing the effect of opening the roller blind from top to bottom. - Pulling 61 and 64 downwards at the same time, the traction rope drives the
movable pulley 1 to rise and no rotation occurs, and the curtain as a whole rises. On the contrary, if 62 and 63 are pulled downwards, the traction rope drives thepulley 1 to descend without rotating, and the curtain as a whole descends. - Pulling 61 and 63 downwards at the same time, the traction rope drives the
pulley 1 to stop lifting and rotate counterclockwise at the same time, the reel can stay at any position and the curtain is released downward. On the contrary, if 62 and 64 are pulled downwards, the traction rope drives thepulley 1 to stop lifting and rotate clockwise at the same time, the reel can stay at any position and the curtain is rolled up. - In this embodiment, two sets of manually-driven bead chain-sprocket wheels are set, and the movement of the two traction wheels is clutched by selecting the combination of the bead chain, so that the curtain can be switched in different movement modes.
