## Title
Lace-like structure of a hive-shaped venetian blind

## Abstract

A lace-like structure of a hive-shaped Venetian blind comprises a blind body made up of a plurality of wave-like arc slats paired up into oval-shaped blind units in cross section. Each wave-like arc slat has a pair of extended flanges disposed at the front and rear sides thereof. Rollers with lace-producing convex edges disposed thereon are adapted to clamp tight the extended flanges thereof and synchronically seal up the pair-up wave-like arc slats via ultrasonic welding art with lace-like patterns cut at the extended flanges thereon via the lace-producing convex edges thereof. Thus, via the lace-producing rollers, the blind body thereof are automatically and synchronically assembled in ready and speedy manner to provide a Venetian blind with lace-like patterns disposed at the front and rear sides thereof in beautiful display.

## Background
BACKGROUND OF THE INVENTION
The present invention is related to a lace-like structure of a hive-shaped Venetian blind, comprising a blind body made up of a plurality of wave-like arc slats paired up into oval-shaped blind units in cross section. Each wave-like arc slat includes a pair of extended flanges disposed at the front and rear sides thereof. Rollers with lace-producing convex edges disposed thereon are adapted to clamp tight the extended flanges thereof and synchronically seal up the pair-up wave-like arc slats via ultrasonic welding art with lace-like patterns cut at the extended flanges thereon via the lace-producing convex edges thereof. Thus, the blind body thereof is easily and readily assembled to provide a Venetian blind with lace-like patterns disposed at the front and rear sides thereof in beautiful display.
Please refer to FIG. 1. A conventional hive-shaped Venetian blind comprises a blind body 10 attached to an upper and a lower beam 11, 12 there-between. The blind body 10 is made up of a plurality of equal spaced and hive-shaped blind units 13 wherein each hive-shaped blind unit 13 is attached to the others via a fixing plate 14. The blind body 10 thereof is gathered up or unfolded via a pull cord 15.
There are some drawbacks to such conventional hive-shaped Venetian blind. First, the blind body 10 is made up of the hive-shaped blind units 13 individually bound together via fixing plates 14, which is not only troublesome and time-consuming in assembly, and also uncompetitive in the market. Second, the blind body 10 is made up of the simple hive-shaped blind units 13, which is rather plain in decoration.
SUMMARY OF THE PRESENT INVENTION
It is, therefore, the primary purpose of the present invention to provide a lace-like structure of a hive-shaped Venetian blind, comprising a blind body made up of a plurality of wave-like arc slats paired up into oval-shaped blind units in cross section. Each wave-like arc slat has a pair of extending flanges disposed at the front and rear sides thereof. Rollers with lace-producing convex edges disposed thereon are adapted to clamp tight the extended flanges thereof and synchronically seal up the pair-up wave-like arc slats to form the blind body thereof in a ready and speedy manner, facilitating the massive production of the Venetian blind thereof.
It is, therefore, the secondary purpose of the present invention to provide a lace-like structure of a hive-shaped Venetian blind wherein the extended flanges of the paired-up wave-like arc slats, clamped by the rollers, are synchronically sealed up via ultrasonic welding art with lace-like patterns cut thereon via the lace-producing convex edges of the rollers to increase the overall beauty of the blind body thereof in display.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Please refer to FIGS. 2, 3. The present invention is related to a lace-like structure of a hive-shaped Venetian blind, comprising a plurality of oval-shaped blind units 21 each made up of two wave-like arc slats 22 correspondingly combined face to face. Each of the wave-like arc slats 22 has a pair of extended flanges 221 disposed at the front and rear sides thereof Rollers 30 with lace-producing convex edges 31 disposed thereon are adapted to clamp tight the extended flanges 221 thereof and synchronically seal up the paired-up wave-like arc slats 22 thereof via ultrasonic. welding art to form oval-shaped blind units 21 as shown in FIG. 2. Meanwhile, the lace-producing convex edges 31 of the rollers 30 will cut through the extended flanges 221 thereof to produce lace-like patterns 221′ at both front and rear sides of the oval-shaped blind units 21 thereof as shown in FIG. 3.
Please refer to FIG. 4. The oval-shaped blind units 21, made up of the paired-up wave-like arc slats 22 with lace-like patterns 221′ cut at the extended flanges 22 thereon, are assembled to form a blind body 20 of the Venetian blind in a ready and speedy manner. Thus, via the lace-producing rollers 30, the paired-up wave-like arc slats 22 are synchronically and automatically assembled with ease and speed, facilitating the massive production of the blind body 20 thereof. Besides, the lace-like patterns 221′ cut by the lace-producing convex edges 31 of the rollers 30 thereof also increase the overall beauty of the blind body 20 thereof in display.

## Claims
