Description

[Detailed Description of the Invention] The present invention relates to a ladder cord for venetian blinds consisting of a pair of vertical cord sections and a horizontal cord section connecting both cord sections at equally spaced points along their length. It is something.

Generally, in Venetian blinds, a ladder cord is suspended vertically from near each end of a horizontal headbox, and a number of slats are placed horizontally between these ladder cords, each slat having a ladder cord at each end. supported by horizontal cord sections.

In this way, a large number of slats are supported horizontally at equal intervals in the vertical direction, and each slat is tilted by moving the pair of vertical cord parts in the front and rear of the ladder cord up and down, thereby providing light shielding. Make adjustments.

Further, the blinds are opened and closed by operating a cord provided separately from the ladder cord.

Conventional Venetian blinds are basically used in a vertically hanging state, and when opening and closing the blinds by operating the lifting cord, the vertical cord part of the ladder cord is hung upward. Collected.

Recently, such Venetian blinds have been installed not in a vertically hanging position, but in an inclined position, for example when installed in an angled window near the ceiling of a building, or in extreme cases in a horizontal position. A compelling need has arisen.

However, in the conventional Venetian grind using a ladder cord, guide rods, guide channel members, etc. made of rigid materials such as metal are provided in inclined or horizontal positions.
The slats must be supported at both ends by these guide members. By making the sections rigid, the slats can be held in an inclined or horizontal position without the need for additional guide members, making them ideal for locations where it was previously difficult to install Venetian blinds. This allows for easy installation.

Figure 1 shows a Venetian blind, in which 1 is the head box, 2 is the ladder cord, and 3 is the slat.

The ladder cord 2 consists of a pair of vertical cord sections and a horizontal cord section connecting both cord sections at equally spaced points along its length, each slat 3 being supported by a horizontal cord section 4. .

2 and 3 are a front view and a cross-sectional view showing the main parts of the present invention, in which the vertical cord portion 5 of the ladder cord 2 is covered with a long metal object 6 having a C-shaped cross section.

As a result, since the vertical cord portion 5 is made of a rigid metal material 6, it will not bend or bend.

According to the structure of the present invention, since the vertical portion of the ladder cord is made rigid, the vertical cord portion of the ladder cord can be placed in an inclined or horizontal state with a horizontal slat placed between a pair of ladder cords. Even when the venetian blind is held at an angle, the venetian blind is reliably held in an inclined or horizontal position without sagging downwards.

However, according to this invention, Venetian blinds can be tilted very easily and inexpensively without the need for additional members such as metal guide members, unlike conventional blinds installed in inclined or horizontal positions. Can be mounted in vertical or horizontal position.

In the ladder cord according to the present invention, since the vertical cord portion is made rigid, it is not possible to open and close the blind by raising and lowering the blind slats using a lifting cord as in the conventional case. By providing a means for moving the slats, it is possible to adjust the light shielding by tilting the slats.

Therefore, when the blind according to the present invention is used as a pre-inclined rear window blind of an automobile, particularly remarkable effects can be expected.
