Description

    FIELD OF THE INVENTION
  • The present invention relates to a positioning member connected to an operation wand for curtains and the wand can be positioned beside the transverse bar on the lower end of the curtain when not in use.
    • BACKGROUND OF THE INVENTION
  • A conventional curtain unit generally includes a driving mechanism which is connected with a lift cord which controls the curtain up and down. The lift cord is in a form of a loop and just hanged on one side of the curtain and can be dangerous for kids.
  • A cord-less curtain is developed and the user has to lift or pull the transverse bar connected to the lower end of the curtain to operate the curtain. However, dust is accumulated on the transverse bar so that the users do not satisfy the design.
  • As shown in FIGS. 6 and 7, another cord-less curtain 7 is to replace the lift cord with an operation wand 75. The curtain generally includes a top case 71 which is a U-shaped case with the driving mechanism received therein. A top bar 72 is connected to the top of the curtain 73 and is connected to one of the driving mechanism. The curtain 73 is connected to the other driving mechanism by wires. A collar is mounted to the top transverse bar 72 and a hook 74 is connected to the collar. The operation wand 75 includes an enlarged end which is engaged with the hook 74 via the opening 741 of the hook 74 so that the wand 75 can be easily connected to the hook 74 or removed from the hook 74. Nevertheless, the users cannot find the wand 75 often because there is no proper positioning device for positioning the wand 75.
  • The present invention intends to provide a positioning member which is connected to the operation wand which is pivotably connected to the transverse bar connected to the lower end of the curtain and the positioning member includes an opening and an engaging space in which the transverse bar is engaged. The wand is positioned parallel to the transverse bar so that the users can easily and convenient use the wand.
    • SUMMARY OF THE INVENTION
  • The present invention relates to an operation wand assembly for curtains and comprises a transverse bar connected to a lower end of the curtain and an operation wand has an end pivotably connected to the transverse bar. A positioning member is connected to the operation wand and includes an opening and an engaging space which communicates with the opening. The operation wand is pivoted toward the transverse bar which is then engaged with the engaging space via the opening.
  • The present invention provides a positioning member on the operation wand which is pivoted toward the transverse bar of the curtain and the transverse bar is engaged with the positioning member.
  • The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.
    • BRIEF DESCRIPTION OF THE DRAWINGS
  • FIG. 1 is a perspective view to show the operation wand connected to the transverse bar of the curtain of the present invention;
  • FIG. 2 is an exploded view to show the operation wand assembly of the present invention;
  • FIG. 3 is a perspective view to show that the curtain is pulled down and the operation wand is hanged on the transverse bar;
  • FIG. 4 is a perspective view to show that the curtain is pushed upward and the operation wand is hanged on the transverse bar;
  • FIG. 5 shows that the operation wand is pivoted toward the transverse bar which is engaged with the engaging space of the positioning member;
  • FIG. 6 shows a conventional curtain with a hook on the transverse bar, and FIG. 7 shows an operation wand is hooked with the hook and pulls the curtain downward.
    •  DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
  • Referring to FIGS. 1 and 2, the operation wand assembly “A” of the present invention for a curtain 1 comprises a transverse bar 2 connected to a lower end of the curtain 1 and the transverse bar 2 is a hollow tube with two open ends. Two end members 6 each include an insertion 62 extending from an end plate 61. The insertions 62 are inserted into the two open ends of the transverse bar 2 and each of the insertions 62 includes a slot 63 defined axially therein so as to define two parts which are pushed inward by the inner wall of the transverse bar 2 to narrow the slot 63 when inserting into the two open ends of the transverse bar 2. The two parts generate an outward force to contact against the inner wall of the transverse bar 2. A protrusion 64 extends radially from one of the two parts of each of the insertions 62 and the transverse bar 2 includes two holes 21 defined through a wall thereof. The two protrusions 64 extend through the two holes 21 to position the end members 6. The user may easily push the protrusions 64 inward to remove the end members 6 out from the two open ends of the transverse bar 2. Two collars are mounted to the transverse bar 2 and two cords are connected between the collars and a fixed top case on a top end of the curtain 1. The cords ensure the transverse bar 2 to be positioned horizontally.
  • A mounting assembly 5 is connected to the transverse bar 2 and includes a sleeve 51 has an engaging tube 53 connected to a lower edge of the sleeve 51. A C-shaped member 52 has two ends thereof connected to two open ends of the engaging tube 53.
  • An operation wand 3 has through hole 31 defined through an end thereof and a ring 32 is connected to the through hole 31. The C-shaped member 52 extends through the ring 32 such that the operation wand 3 can be freely pivoted relative to the C-shaped member 52.
  • A positioning member 4 is connected to the operation wand 3 and includes an opening 42 and an engaging space 41 which communicates with the opening 42. The operation wand 3 is a polygonal wand and the positioning member 4 includes a polygonal space in which the operation wand 3 is securely engaged. The transverse bar 2 is sized to be engaged with the engaging space 41 via the opening 42. Two inclined and outward plates extend from two ends of the opening 42 and a width of the opening 42 is smaller than the diameter of the transverse bar 2. The positioning member 4 is made by flexible material so that the opening 42 is enlarged when clamping the transverse bar 2.
  • As shown in FIG. 3 and 4, the user can pull or push the operation wand 3 to lower or lift the curtain 1 which is then positioned by the driving mechanism (not shown) in the top case of the curtain assembly.
  • As shown in FIG. 5, when the curtain 1 is positioned as shown in FIGS. 3 and 4, the user may pivot the operation wand 3 and push the positioning member 4 toward the transverse bar 2 which is then moved through the opening 42 by slightly expand the opening 42 and then engaged with the engaging space 41. By the positioning member 4, the operation wand 3 can be positioned parallel to and next to the transverse bar 2, the operation wand 3 does not block the view from the window and the user can easily disengage the operation wand 3 from the positioning member 4 to operate the curtain 1.
  • While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
