Description

Buffer for small roller blinds

The utility model relates to a buffer device for a small roller blind, in particular to a volume outer diameter of a buffer device which is completely assembled, and is suitable for use in a roller blind on a door and window, and can also be applied to a small roller blind inside a limited thickness of an automobile door, and can be widely used. .

According to the current home, office use curtain shade or decoration, has become quite popular phenomenon, but for the curtain to open, fold the way, mostly use the drawstring to open or close the curtain, but the curtain is only suitable for louver curtains or The curtains that open to the left and right ends and fold together cannot be applied to a curtain. Therefore, the inventor specially developed the blood and tested a curtain device. The curtain device is attached to the left end of the track. The curtain fabric is opened downwards clockwise, and then pulled up, the curtain cloth is folded upwards against the clock. When the curtain fabric is folded, the cushioning device is arranged at the right end of the track to form a collapse, but the curtain is folded. In the case of cloth, the friction coefficient between the buffer devices is large, and the frictional force generated in the opposite direction is also large, which is likely to cause noise.
In order to prevent excessive noise, the inventor of the present invention applied for Patent Announcement No. 484397 "Improvement of Curtain Retraction Buffering Device", please refer to Figures 1 to 4, which is a track 11, an adjusting device 12, a buffer The device 13, a pull-and-loop device 14 having a resilient member 141 and a curtain fabric 15 are assembled to form a curtain device 1. The buffer device 13 includes an outer casing 130, a sleeve 131 disposed inside the outer casing 130, and an outer sleeve 132 having a guiding rod 1321 at one end of the sleeve 131. A cover body 133 is integrally sleeved between the sleeve 131 and the outer casing 130, and a rotating block 134 is engaged with the guiding rod 1321 of the outer casing 132. The lubricating oil injected into the inner edge of the outer casing 130 of the cushioning device 13 acts as a resistance, so that the curtain cloth 15 does not cause a large noise due to a large friction coefficient when it is folded, and does not affect the hearing.
However, the buffer device 13 of the case can avoid the noise generated by the large friction coefficient between the curtain fabrics 15 , but a sleeve 135 is formed inside the sleeve 131 and a spring 136 is surrounded by the shaft 135 . Therefore, the outer diameter of the sleeve 131 must be increased, and the outer diameter of the sleeve 131 is increased for the inner sleeve to be used for the spring 136, and the outer diameter of the spring 136 is added to the outer diameter of the sleeve 131. Then, the sleeve 131 is placed inside the outer casing 130, so that the outer diameter of the entire assembly of the cushioning device 13 is further increased (as shown in FIG. 4), and the manufacturing cost thereof is high. Therefore, it is easy for the cushioning device 13 to increase the outer diameter of the volume, and it is very limited to reduce the outer diameter of the cushioning device 13. Therefore, the cushioning device 13 of this case can only be assembled to the curtain device 1 used on the door and window, and it is difficult to assemble the curtain device 1 to a small roller blind used inside the limited thickness of the automobile door.
