Description

Curtain controller structure

This creation is about a curtain controller structure, especially an innovative structure of a curtain controller that has the safety function of preventing children from going around the neck.

In traditional Roman blinds, roller blinds or venetian blinds, the controller structure is mainly driven by the bead chain rope to drive the bead chain disc, and then the bead chain disc drives the curtain rod to move through the transmission member, and then controls the curtain body to roll or sag put. However, because the bead chain of the traditional curtain controller is exposed, it may be accidentally wrapped around the neck due to children's curiosity and play, resulting in a dangerous situation of being strangled. Therefore, some curtain manufacturers have developed a way that when the child is wrapped around the neck of the bead chain rope, the bead chain disk can be detached from the controller to release the bead chain rope around the neck and ensure the safety of the child.

For example, TW M549585, "Safety Device for Curtain Controller (1)", the controller can use the tapered sleeve relationship between the shaft and the bead chain disc when the bead chain is momentarily stressed, so that the bead chain disc Disengage the shaft laterally, and push the outer cover laterally, to separate the latching piece pivotally connected to the lower end of the base from the buckle state of the outer cover, so that the bead chain and the bead chain fall off from the base to prevent The situation around the neck occurs.

Another example is No. TW M530617 "Bead Curtain Drive Structure with Safe Disengagement", a bead curtain drive structure with safe disengagement. When a bead chain is wrapped around the neck of a young child, the bead chain is subject to the gravity of pulling down, which will cause The bead applies force to the axial groove. At this time, the axial groove is designed to be inclined at an angle to the radial direction to allow the bead to roll and slide into and out of the bead groove, and to resist the cover. The force pushes the positioning groove of the cover away from the positioning column, and the state of lifting the cover is formed, so that the bead chain is separated from the bead chain turntable and falls, to achieve safety protection measures to prevent young children from going around the neck.

Refer to No. TW I581740 "Safety Device for Curtain Controller". When the bead chain is momentarily stressed, the column and sleeve hole that are tapered between the shaft and the bead chain disk can be used to make the bead chain side To detach the shaft, and push the outer cover laterally to separate the lower end of the outer cover from the buckle state of the base, so that the bead chain disk and the bead chain fall off from the base, so as to prevent children or users from winding. The safety effect of the neck.

In the above case, when the bead chain disk is detached from the controller, the outer cover (protective cover) on the side is opened outward to the side, so that when installing the curtain, a space must be reserved. The space is When the bead chain around the neck occurs, the outer cover (protective cover) of the controller can be pushed by the bead chain disk, and the lower end can be detached from the buckle state and smoothly opened laterally; however, in actual installation The site may not be able to reserve side space for the curtain controller to prevent it from being used around the neck due to the interior decoration or the design of the building, so that the structure of the previous case needs to be improved.

In addition, refer to No. TW M483042 "Assembly Structure of Bead Chain Seat of Curtain Rod". The side cover and the base plate are combined or separated by a longitudinal sliding method. Therefore, when a bead chain around the neck occurs, the bead chain and The cover plate will be separated from the base plate longitudinally; this structure has improved the disadvantage that the side cover needs to be opened laterally and space needs to be reserved in the previous case.

Today, the author is in view of the above-mentioned previous cases in the actual implementation and use of the shortcomings, and on the basis of No. TW M483042, and then straight out of the installation without the need to reserve side space control Device.
