The winding rod 61 extends horizontally, and is adapted to be mounted rotatably to or in the vicinity of the upper edge of the window 3. In this embodiment, the winding rod 61 is mounted rotatably to the hori zontal frame 4.
A top end portion of each winding piece 62 is connected to the winding rod 61. Each winding piece 62 is able to be wound around the winding rod 61 to be shortened, and unwound from the winding rod 61 to be lengthened and to extend downwardly along or next to the rear side of the covering portion 51 of the curtain unit 5.
Each of the abutting rods 63 is mounted horizontally and removably to or in the bottom end portion of a respective one of the winding pieces 62, is larger than the lower slots 541, and abuts against a bottom surface of the lower tube 54.
Two of the covers 64 are used for covering end portions of each of the abutting rods 63.
The control rod 65 is connected to the winding rod 61 in such a manner that the winding rod 61 can be rotated by manipulation of the control rod 65. In this embodiment, manipulation of the control rod 65 to rotate about its axis results in rotation of the winding rod 61 to rotate about its own axis. Also, in this embodiment, the axis of the winding rod 61 is roughly perpendicular to the axis of the control rod 65 when the control rod 65 hangs
8 freely downward from its connection to the winding rod 61.
Referring to Figures 3, 5, and 6, in this embodiment, the bottom end portion of each of the winding pieces 62 i s wound into a tube portion 621, and one of the abutting rods 63 is inserted into the tube portion 621. The outer diameter of each of the covers 64 is greater than the diameter of each of the tube portions 621, such that each, of the abutting rods 63 is confined within the respective tube portion 621 when the respective covers 64 are disposed on the abutting rod 63. Through this configuration, each of the abutting rods 63 is connected removably to the bottom end portion of the respective winding piece 62. The manner in which the abutting rod 63 is connected to the bottom end portion of the respective winding piece 62 is not limited to the aforesaid configuration.
Each of the winding pieces 62 extends through the respective upper and lower slots 531, 541 from the winding rod 61. The bottom end portion of each winding piece 62 is restricted in upward movement relative to the lower tube 54. When the winding rod 61 is rotated to thereby wind the winding pieces 62 therearound, the lower tube 54 is moved upwardly together with the bottom end portions of the winding pieces 62 until the lower tube 54 abuts against the lower one of the upper tubes 53, thereby folding the covering portion 51 of the
Referring to Figures 3, 5, and 6, in this embodiment, the bottom end portion of each of the winding pieces 62 i s wound into a tube portion 621, and one of the abutting rods 63 is inserted into the tube portion 621. The outer diameter of each of the covers 64 is greater than the diameter of each of the tube portions 621, such that each, of the abutting rods 63 is confined within the respective tube portion 621 when the respective covers 64 are disposed on the abutting rod 63. Through this configuration, each of the abutting rods 63 is connected removably to the bottom end portion of the respective winding piece 62. The manner in which the abutting rod 63 is connected to the bottom end portion of the respective winding piece 62 is not limited to the aforesaid configuration.
Each of the winding pieces 62 extends through the respective upper and lower slots 531, 541 from the winding rod 61. The bottom end portion of each winding piece 62 is restricted in upward movement relative to the lower tube 54. When the winding rod 61 is rotated to thereby wind the winding pieces 62 therearound, the lower tube 54 is moved upwardly together with the bottom end portions of the winding pieces 62 until the lower tube 54 abuts against the lower one of the upper tubes 53, thereby folding the covering portion 51 of the
9 curtain unit 5, as shown in Figure 7. That is, the third cloth segment 513 of the covering portion 51 is folded upwardly through such an operation. With continued rotation of the winding rod 61, the covering portion 51 is eventually folded fully upwardly, as shown in Figure 8.
Referring to Figures 3, 4, and 8, it is noted that the upper tubes 53 and the lower tube 54 of the curtain unit 5 are Rulled up and released to displace downwardly by manipulation of the winding pieces 62, rather than a cord as in the conventional roman curtain. This way, strangling injury occurring, for example, when the cord of the conventional roman curtain wraps around a child's neck may be avoided.
In addition, by simply removing the abutting rods 63, the winding pieces 62 can be removed from the upper and lower slots 531, 541, and the fastening member 52 can be separated from the horizontal frame 4 so that the covering portion 51 of the curtain unit 5 can be removed for cleaning, or for replacement with another covering portion 51 with a different style. Each of the winding pieces 62 may also be removed for cleaning or replacement. Hence, such removal of the covering portion 51 is very simple. Also, such a structure is simple, ultimately resulting in a lower cost for the roman curtain of the present invention.
Additional embodiments will now be described. To simplify the description of each of the embodiments to follow, the following preferred embodiments are shown and described as if there is only one winding piece 62 and one abutting rod 63 associated therewith, one upper 5 tube 53, and one lower tube 54. However, in practice, each of the embodiments to follow includes two winding pieces 62 and two abutting rods 63 associated respectively therewith, two upper tubes 53, and one lower tube 54, as in the first preferred embodiment.
