SECURING DEVICE FOR SECURING WIRES OF WINDOW SHADES

Abstract

A securing device for a window shade includes a securing member connected to the bottom bar of the window shade, and the securing member has a first end and a second end. The first end of the securing member faces the bottom bar, and the second end of the securing member faces a direction away from the bottom bar. The second end has at least one securing slot defined axially therein. The width of the at least one securing slot is gradually narrowed from the second end toward the first end of the securing member. The narrowest end of the at least one securing slot is a clamping notch which is used to clamp the wire of the window shade.

Claims

1. A securing device for a window shade, and comprising: a securing member which is adapted to be connected to a bottom bar of a window shade, the securing member having a first end and a second end, the first end of the securing member adapted to face the bottom bar, the second end of the securing member adapted to face a direction away from the bottom bar, the second end having at least one securing slot defined axially therein, a width of the at least one securing slot being gradually narrowed from the second end toward the first end of the securing member, a narrowest end of the at least one securing slot being a clamping notch which is adapted to clamp a wire of the window shade.

2. The securing device as claimed in claim 1, wherein the at least one securing slot is an inverted V-shaped slot.

3. The securing device as claimed in claim 1, wherein there are two securing slots defined in the second end of the securing member, the two securing slots are located diametrically opposite from each other.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0018] Referring to FIGS. 1 and 2, the securing device of the present invention comprises a securing member 10 which is a tubular member with a passage 11 defined axially therethrough. The securing member 10 is connected to the bottom bar 50 of a window shade. The securing member 10 has a first end 12 and a second end 13, wherein the first end 12 of the securing member 10 faces the bottom bar 50, and the second end 13 of the securing member 10 faces a direction that is away from the bottom bar 50. The second end 13 has at least one securing slot 15 defined axially therein. In this embodiment, there are two securing slots 15 defined in the second end 13 of the securing member 10. The two securing slots 15 are located diametrically opposite from each other. Each of the securing slots 15 is an inverted V-shaped slot. The width of the each securing slot 15 is gradually narrowed from the second end 13 toward the first end 12 of the securing member 10. The narrowest end of each of the securing slots 15 is a clamping notch 152 which is featured to clamp a wire 56 extending through the slats 55 and the bottom bar 50 of the window shade.

[0019] As shown in FIGS. 3 and 4, a tubular member 52 is engaged with the hole 51 of the bottom bar 50. The distal end of the wire 56 extends through the passage 11 from the first end 12 and extends beyond the second end 13 of the securing member 10. The distal end of the wire 56 is then engaged with one of the securing slots 15 and bent upward. The distal end of the wire 56 then enters into the passage 11 again from the first end 12 and comes out from the second end 13. The wire 56 is pulled tightly in the axial direction of the securing member 10. The securing member 10 and the wire 56 are together inserted into the tubular member 52. The securing member 10 is squeezed inward to secure the wire 56.

[0020] It is noted when the wire 56 is engaged with the securing slot 15, the wire 56 is securely clamped by the clamping notch 152 which squeezes the wire 56 and secures the wire 56 to ensure that the wire 56 does not loose. Therefore, the slats and the bottom bar 50 are always kept in horizontal direction.

[0021] 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.
