Safety buckle for a window blind assembly

Abstract

A safety buckle for a window blind assembly includes a connecting part, a bar section, and a pair of surrounding arms. The connecting part is adapted for mounting on one side of the window blind assembly, and has two ends spaced apart from each other in a longitudinal direction. The bar section extends along the longitudinal direction and is connected to the two ends of the connecting part. Each of the surrounding arms extends along an arc from a corresponding one of the ends of the connecting part toward another one of the ends of the connecting part. The surrounding arms cooperate with the bar section to define a buckle hole that is adapted for extension of a pull cord unit of the window blind assembly therethrough. The surrounding arms define an escape path therebetween that is in spatial communication with the buckle hole.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a safety buckle for a window blind assembly, more particularly to a safety buckle that is mounted on a window blind assembly and that is configured to allow a pull cord unit of the window blind assembly extending therethrough to escape therefrom.[0003]2. Description of the Related Art[0004]Referring to FIG. 1, a conventional window blind assembly is exemplified as a roman blind 1 that includes a top rail 11 adapted to be disposed at a top edge of a window, a drawable light-blocking curtain 12 hung from the top rail 11, a plurality of buckles 13 disposed at a rear side of the light-blocking curtain 12, and a pull cord 14 fixedly connected to a lower section 121 of the light-blocking curtain 12 for drawing up and lowering the light-blocking curtain 12. The buckles 13 are vertically spaced apart from each other, and the pull cord 14 vertically extends through each of the buckles 13.[0005]Ho...

AI Technical Summary

Benefits of technology

"The present invention provides a safety buckle for a window blind assembly that can prevent accidental strangulation. The safety buckle includes a connecting part, a bar section, and a pair of surrounding arms. The connecting part is mounted on the light-blocking unit of the window blind assembly and has two ends. The bar section extends along the longitudinal direction and is connected to the two ends of the connecting part. The surrounding arms extend along an arc from the ends of the connecting part and define a buckle hole that allows the pull cord unit to escape from the buckle hole into an escape path when the pull cord unit is subjected to a pulling force in a transverse direction that is transverse to the longitudinal direction and that is away from the bar section. This design ensures the safety and reliability of the window blind assembly."

Problems solved by technology

However, such an arrangement is dangerous for children playing with the roman blind 1.

It is possible that a child extends his / her neck between the light-blocking curtain 12 and the pull cord 14 when playing with the roman blind 1, and it may be difficult for the child to escape when the child's neck is restricted therebetween.
