The sheltering portion 411 has a first cloth segment 412, a second cloth segment 413, a third cloth segment 414, and a fourth cloth segment 415, which are arranged vertically in this order. The sleeving portions 416 horizontally extend, and are respectively disposed at connecting portions between the first cloth segment 412 and the second cloth segment 413, between the second cloth segment 413 and the third cloth segment 414, and between the third cloth segment 414 and the fourth cloth segment 415.
Referring to Figures 3, 4 and 5, in the preferred embodiment, the clamping unit 5 includes three connecting clamps 50 and three connecting tubes 53. The connecting clamps 50 extend horizontally and are vertically spaced apart from each other.
In an effort to simplify the discussion to follow immediately below, the structure as it relates only to one of the connecting clamps 50 and one of the connecting tubes 53 will be described.
The connecting clamp 50 has a first clamping portion 51 that clamps onto the folding curtain cloth 41 and a second clamping portion 52 that clamps onto the roller blind cloth 34.
The connecting tube 53 extends horizontally on a rear surface of the roller blind cloth 34, and is connected to a respective one of the second clamping portions 52 of the connecting clamps 50.The first clamping portion 51 of the connecting clamp 50 has a front rod 511 and a rear rod 512 which are disposed adjacent to each other and end portions of which are connected to each other.
The front rod 511 and the rear rod 512 of the first clamping portion 51 define a first slot 513 for clamping onto the folding curtain cloth 41. In this embodiment, the front rod 511 of the first clamping portion 51 is inserted into a respective one of the sleeving portions 416, such that the first clamping portion 51 clamps onto the sleeving portion 416.

In this embodiment, the front rod 521 of the second clamping portion 52 is coupled to the rear rod 512 of the first clamping portion 51. In some embodiments, a metal rod can be bent to form the connecting clamp 50.
In other embodiments, the connecting clamp 50 can be formed using plastic material. Hence, the present invention is not limited with respect to the material and fabricating method used for the connecting clamp 50.
The connecting tube 53 is sleeved on the rear rod 522 of the second clamping portion 52 of the connecting clamp 50. End portions of the connecting tube 53 of the clamping unit 5 are formed with slits 532 that extend horizontally and facilitate inserting of the rear rod 522 of the second clamping portion 52 into the connecting tube 53. An inner surface of the connecting tube 53 of the clamping unit 5 is formed with a plurality of lengthwise ribs 533. The ribs 533 are used for enhancing the strength of the connecting tube 53 so as to prevent the same from being bent when in use.
Referring to Figures 1, 2, and 3, the roller blind cloth 34 of the roller blind unit 3 and the folding curtain cloth 41 of the curtain member unit 4 are respectively unwound and unfolded downwardly when the window 2 is covered. On the other hand, the roller blind cloth 34 of the roller blind unit 3 is wound upwardly by pulling the cord 33 of the roller blind unit 3 which results in rotation of the roller rod 32. When the roller blind cloth 34 is wound around the roller rod 32, the weighting rod 35 moves upwardly to first push against the lowest connecting clamp 50 and the lowest connecting tube 53, and to subsequently displace the lowest connecting clamp 50 and the lowest connecting tube 53 in an upward direction. As a result, the third cloth segment 414 is folded as shown in Figure 6. Referring to Figures 3 and 6, this process is repeated with the continued winding of the roller blind cloth 34, such that the roller blind cloth 34 is fully wound around the roller rod 32, and the second cloth segment 413 and the first cloth segment 412 are eventually folded upwardly as shown in Figures 7 and 8.
Figures 7 and 8 show that the folded curtain member unit 4 has a sophisticated, classic appearance.
In the present invention, the roller blind unit 3 is provided with the folding curtain cloth 41 and the clamping unit 5 is mounted between the curtain member unit 4 and the roller blind unit 3. Hence, the result is a style resembling a roman blind, a structure that allows for mounting that is simple, and an overall design in which the cost thereof is reduced.
Referring to Figures 1, 2, and 4, the folding curtain cloth 41 uses the fastening member 42 for attachment to the horizontal frame 31. Accordingly, by simply removing the fastening member 42 and the connecting 5 clamps 50, the folding curtain cloth 41 can be removed for cleaning or for replacement with another folding curtain cloth 41 with a different style. In addition, the slit 532 of the connecting tube 53 of the clamping unit 5 allows for convenient insertion of the rear rod 10 522 of the connecting clamp 50 into the connecting tube 53.
Figure 9 illustrates a second preferred embodiment of the window blind assembly according to the present invention. The second preferred embodiment differs from the first preferred embodimentinthefollowingaspects.
The connecting tube 53 of each of the connecting clamps 50 extends into a respective one of the sleeving portions 416, and is sleeved on the front rod 511 of the first clamping portion 51 of the corresponding connecting clamp 50. During the process of being folded upwardly, the connecting tube 53 can horizontally support the folding curtain cloth 41.

In this embodiment, the front rod 521 of the second clamping portion 52 is coupled to the rear rod 512 of the first clamping portion 51. In some embodiments, a metal rod can be bent to form the connecting clamp 50.
In other embodiments, the connecting clamp 50 can be formed using plastic material. Hence, the present invention is not limited with respect to the material and fabricating method used for the connecting clamp 50.
The connecting tube 53 is sleeved on the rear rod 522 of the second clamping portion 52 of the connecting clamp 50. End portions of the connecting tube 53 of the clamping unit 5 are formed with slits 532 that extend horizontally and facilitate inserting of the rear rod 522 of the second clamping portion 52 into the connecting tube 53. An inner surface of the connecting tube 53 of the clamping unit 5 is formed with a plurality of lengthwise ribs 533. The ribs 533 are used for enhancing the strength of the connecting tube 53 so as to prevent the same from being bent when in use.
Referring to Figures 1, 2, and 3, the roller blind cloth 34 of the roller blind unit 3 and the folding curtain cloth 41 of the curtain member unit 4 are respectively unwound and unfolded downwardly when the window 2 is covered. On the other hand, the roller blind cloth 34 of the roller blind unit 3 is wound upwardly by pulling the cord 33 of the roller blind unit 3 which results in rotation of the roller rod 32. When the roller blind cloth 34 is wound around the roller rod 32, the weighting rod 35 moves upwardly to first push against the lowest connecting clamp 50 and the lowest connecting tube 53, and to subsequently displace the lowest connecting clamp 50 and the lowest connecting tube 53 in an upward direction. As a result, the third cloth segment 414 is folded as shown in Figure 6. Referring to Figures 3 and 6, this process is repeated with the continued winding of the roller blind cloth 34, such that the roller blind cloth 34 is fully wound around the roller rod 32, and the second cloth segment 413 and the first cloth segment 412 are eventually folded upwardly as shown in Figures 7 and 8.
