Problems solved by technology

[0006] The roller blinds disclosed in the above patents all rely on the gravity of the reel and the pulling force of the traction rope to drive the reel to rotate. If the gravity of the reel itself is not enough, it will be difficult for the reel to rotate when it is raised and lowered, thereby destroying the top-opening effect.
In addition, the roller blinds disclosed in the above patents all rely on the winder to wind or loosen the traction rope to drive the reel. For horizontal installation
At the same time, the setting of the winder takes up the design space, which is not conducive to the optimization of the whole system

Embodiment 1

[0026] Such as figure 1 As shown, a roller blind that can be freely opened and closed up and down includes a reel (not shown in the figure), a movable pulley 1, a traction rope and a cord 2, the upper end of the cord 2 is fixed on the reel, the lower end is a free end, and a counterweight 6 is provided. .

[0027] The traction rope of the present invention comprises a lifting section 31 and a pull-down section 32. The two ends of the lifting section 31 are connected with a wire winder 41 and a wire winder 42, and the two ends of the pull-down section are connected with a wire winder 43 and a wire winder 44. The lifting section 31 goes around the movable pulley 1 and tensions upwards, and the pull-down section 32 tensions the movable pulley downward, so that the movable pulley 1 remains stable at any time.

[0028] When the wire winder 42 and the wire winder 44 are stationary, the wire winder 41 is released and the wire winder 43 is wound up, the winding shaft moves downward a...

Embodiment 2

[0031] Such as figure 2 As shown, a roller blind that can be opened and closed freely up and down includes a reel (not shown in the figure), a movable pulley 1 and a cord 2, and the traction rope includes a lift-up section 31 and a pull-down section 32, which are connected by connecting sections 33 and 34 to form a closed-loop structure , the tensioning arrangement is on four tensioning wheels, wherein the tensioning wheel 51 and the tensioning wheel 52 are traction wheels, which can be manually driven or driven by a motor. The traction rope can be a variety of wire ropes with small elongation, or a bead chain, or a timing belt can also be used. Of course, the tension pulley and movable pulley also need to choose a structure that matches the traction rope. When the traction rope adopts the bead chain, the tension pulley and the movable pulley are sprockets; when the traction rope adopts the synchronous belt, the tension pulley and the movable pulley are synchronous pulleys. ...

Embodiment 3

[0040] Such as Figure 5 Shown, the setting of reel (not shown in the figure), guide groove 8, movable pulley 1, cord 2, traction rope and fixed pulley is the same as embodiment 2, and there is no intermediate gear and fixed tooth seat. The tensioning wheel 51 and the tensioning wheel 52 are driven by the motor 91 and the motor 92 respectively, and the motor 91 and the motor 92 are controlled by the controller 10, and various programs can be set by the controller 10 to control the rotation and static of the motor 91 and the motor 92 respectively. And different rotation directions, so that the two traction wheels can realize the combined action as described in embodiment 2, so that the curtain can realize the effect of opening or closing or covering any position of the window.

[0041] Make the diameter of the movable pulley and the reel the same or close to ensure that when the curtain is opened or retracted, the bottom end of the curtain always remains motionless or the up an...

Abstract

The invention discloses a roller shutter capable of being opened and closed freely in the up-down direction. The roller shutter comprises a winding shaft, a traction rope and a traction device. A movable pulley is arranged at the end of the winding shaft. The traction rope comprises a lifting-up section and a pulling-down section which are pulled by the traction device to move synchronously. The lifting-up section and the pulling-down section pass through the movable pulley and then are tensioned upwards and downwards correspondingly so as to enable the movable pulley to be kept stable. According to the roller shutter, the lifting-up section and the pulling-down section are arranged and tension the movable pulley in the two opposite directions so as to enable the movable pulley to be keptbalanced; and when the lifting-up section and the pulling-down section are pulled to move synchronously, the movable pulley can autorotate while rising and falling, and accordingly the effect that theroller shutter is opened and closed freely in the up-down direction can be achieved.

Description

technical field [0001] The invention relates to a roller blind, in particular to a roller blind which can be opened and closed freely up and down with more reliable operation. Background technique [0002] Roller curtains are easy to use and elegant in appearance, and are widely used in home life and office spaces. The commonly used method for existing roller blinds is to fix the reel on the upper end of the window, turn the reel, and wind up or release the curtain. This curtain at first begins to open from the lower part of the window, so that the upper part of the window is shaded and the lower part is daylighted. [0003] In real life, private spaces such as rooms, reception rooms, and bathrooms, school classrooms, and some office spaces often require the lower half of the window to block the line of sight, while the upper half is used for lighting. This just needs a kind of upper opening type roller blind. In order to block the line of sight or block the direct light ...
