The blind includes an upper beam, a plurality of cloth drapes, a plurality of swing weights and a plurality of covering caps. The upper beam is an elongated tube having a first adhesive buckle belt disposed at the front side thereof Each cloth drape is a vertically extended rectangular fabric piece having a second adhesive buckle belt of equal width to that the first adhesive buckle belt so that the cloth drape can be removably secured to the upper beam. Each swing weight attached to the bottom of each cloth drape is made up of a snap piece and a retaining piece that are forced into engagement with each other with the bottom of the cloth drape clamped therebetween. Each snap piece is a long rod having a central open groove and an upper retaining ditch and a lower retaining ditch. The longitudinal edges of both the upper and lower retaining ditch are provided with an outwardly bent slide engagement section. The retaining piece of the lower swing weight is a long rod of the same length as that of the snap piece. The longitudinally extended upper and lower edges of the retainmg piece are provided with an inwardly bent resilient locking section having a clamping nb extended in the longitudinal direction so as to permit the slide engagement section of the snap piece to be snapped into engagement with the receiving space defined by the resihent locking section and the clamping rib with the cloth drape clamped between the snap piece and the retaining piece with ease and speed in a precise manner.

A prior art vertical blind is equipped with an upper beam tO, a plurality of cloth drapes 20, a plurality of lower swing weights 30, a plurality of swing weights 30, a plurality of restraint plates 31 and a plurality of sealing caps 32. The upper beam 10 is of a tubular shape with the front side thereof secured to an adhesive buckle belt ! I. Each cloth drape 20 is of a vertical form of a proper wrdth with an adhesive buckle belt 21 secured to the top edge thereof. Each lower swing weight 30 is of an identical length to that of each cloth drape 20. Its cross section is of an H-like shape with a hollow interior and a partition wall 301 extends axially at the middle thereof to form a top passage room 302. At the top and bottom sides of the swing weight 30 is provided with a slot respectively. The edges of each slot are equipped with a downwardly bent retaining hook 303. The restraint plate 31 is as long as the swing weight 30. The sealing caps 32 are made m conformance to the ends of the swing weight 30 and have a retaining block 321 respectively.

As shown in Figs. 2,3, 4, the cloth drapes 20 are secured to the upper beam 10 by engaging the adhesive buckle belts 21 with the adhesive buckle belts 11 to get the cloth drapes vertically hanged. Each swing weight 30 is placed at the bottom of the cloth drape 20 whose bottom end is led through the top slot into the top passage room 302 with the restraint plate 31 located In the passage room 302. Fmally, the sealing caps 32 are registered with the ends of the swing weight 30 with the retaining blocks 321 in abutment against the retaining hooks 303 to complete the assembly.

There are several disadvantages associated with such a pnor art swing weight given as below : 1. The attachment of the swing weight to the bottom edge of the cloth drape is relatively

difficult and time consuming.

2. The swing weights are easily out of alignment with one another when attached to the cloth drapes.

3. The insertion of the restraint plate in the passage room of the swing weight can easily result in the push astray of the cloth drape.

The upper beam 40 is of a long tubular structure having on Its longitudinal side a female or male adhesive buckle belt 41. Each cloth drape 50 is of an oblong shape of a proper width and has a female or male adhesive buckle belt 51 secured at the upper edge thereof. Each mdividual lower swing weight 60 is made up of a snap piece 61 and a retaining piece 65 that are integrally snapped mto one piece. The snap piece 61 is a long rod having a central open groove 62 and an upper retaining ditch and a lower retaining ditch 63. The longitudinal edges of both the upper and lower retaming ditch 63 are provided with a slide engagement section 64. The retaining piece 65 of the lower swing weight 60 is a long rod of the same length as that of the snap piece 61. The

longitudinally extended upper and lower edges of the retaining piece 65 are provided with an inwardly bent resilient locking section 66 having a clamping rib 67 extended in the longitudinal direction. The sealing caps 70 are plates made in conformance to the shape of each end of the lower swing weights 60 and has a projected supporting block 71 at the internal surface thereof.

To get the same assembled, as shown in Fig. 6 and Fig. 7, the male or female adhesive buckle belt 51 fixed to the top edge of each cloth drape 50 is engaged with the other female or male buckle belt 41 secured to the front side of the upper beam 40. The cloth drape 50 hangs naturally down. First, the snap piece 61 and the retaining piece 65 of the lower swing weight 60 are respectively disposed at the front side and the rear s1de of the cloth drape 50 and are then they are snapped mto registration with each other with force, rendering the cloth drape 50 to be clamped in place between the snap piece 61 and the retaining pieces 65. The resilient locking sections 66 of the retaining piece 65 slide into registration with the lower and upper retaining ditches 63, together with the cloth drape 50, moving along the slide engagement sections 64 of the snap piece 61. As shown in Fig. 7, the bottom section of the cloth drape 50 is forced into the space defined between the resilient locking sections 66 and the clamping ribs 67 disposed at the upper and lower edge of the retaining piece 65 Afterwards, the projected supporting blocks 71 of the sealing caps 70 are snapped into registration with the two ends of the lower swing weights 60 to complete the assembly. The lower swing weights 60 can be placed at a proper position adjacent the bottom of the cloth drape 50, and the redundant portion of the same can be tnmmed to make the cloth drape 50 flush with the edge of the lower swing weights 60.

Referring to Fig. 8, another embodiment of the present invention is illustrated.
