[Detailed description of the device]

[0001]

[Industrial application] The present invention is a pair of front and rear vertical cables.
A ladder-shaped ladder code comprising two horizontal cord portions horizontally connecting the vertical code portions to each other with a vertical gap between them is provided in the horizontal direction. And a plurality of slats are respectively supported by the horizontal code portions of the ladder cords, and a bottom rail is disposed at the lower end of these slats, and the above ladder cords are arranged. The lower end of the cord is connected to the bottom rail, and the ladder cord
The present invention relates to a horizontal blind of a type in which a plurality of slats are rotated by relatively elevating vertical cord portions in front of and behind the window to adjust light shielding, and particularly, it is used for a horizontal blind of this type. Bottom rail.

2. Description of the Related Art In a horizontal blind of the above type,
The front and rear vertical code parts of the ladder code are fixed to the both side edges of the bottom rail by tape holders, and the vertical code parts before and after the ladder code are relatively vertically moved. The slat group is rotated by moving the slat group.

[0003]

In the horizontal blind of the above-mentioned type, it is impossible to rotate the bottom rail to a completely vertical position, so that the side edges of the upper and lower slats contact each other. The slat cannot be rotated to the vertical position. Particularly, in a blind attached to a skylight or a tilted window, the tendency becomes more remarkable due to a guide wire that supports the slats along the window surface. The present invention seeks to provide a horizontal blind bottom rail that allows the slat to be pivoted to a completely vertical position. A structure in which a ladder tape receiving pulley is attached to the bottom rail so that the lower end of the ladder tape is received by the tape receiving pulley is disclosed in Japanese Utility Model Publication 58.
No. 28157, the structure disclosed in this prior art does not allow the lifting code to be mounted in the same position as the ladder tape, and therefore the lifting code is mounted on the ladder tape.
Must be attached to the bottom rail in a different position than the bottom rail. In such a structure, since the elevating code and the ladder tape are located separately, not only is it unfavorable in appearance, but also the workability in assembling the blind is poor. The present invention does not have such drawbacks, and it is an object of the present invention to provide a bottom blind rail of a horizontal blind capable of rotating the slats to a completely vertical position as described above.

[0004]

Means and operation for solving the problem The present invention is, as a means for solving the above problems, a bottom drum receiving fixed to the bottom rail at a position to mount the ladder cord, the upper surface of the bottom drum receiving The protruding portion provided is projected on the upper surface of the bottom rail, and the bottom drum is supported in the bottom drum receiver so as to be rotatable around the central axis of the bottom rail. Inserting holes for inserting the front and rear vertical cord portions of the ladder cord are provided, the front and rear vertical cord portions of the ladder cord are introduced into the bottom drum receiver through the insertion holes, and both vertical cords are wound around the bottom drum. A lifting cord that connects the lower ends of the parts together and that raises and lowers the slats is vertically extended through the slats between the vertical cord parts before and after the ladder cord. A horizontal blind, characterized in that attached to the lower end projecting portion of the bottom drum受上unit
To provide. According to the horizontal blind described above, when a pair of vertical cord portions before and after the ladder cord are moved up and down relatively to rotate the slat, the ladder cord freely moves around the bottom drum to move the slats. Rotate to a completely vertical position.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the embodiments shown in FIGS. In the drawings, reference numeral 1 denotes a horizontal slat of a horizontal blind, and a plurality of slats 1 are supported by two or more horizontally-spaced ladder cords 2 at regular intervals in the vertical direction. It Each ladder code 2 has a pair of front and rear vertical code portions 2A and 2B and a plurality of horizontal code portions 2C which vertically connect the vertical code portions with a space therebetween. Each slat 1 has a horizontal code portion 2
Supported on C. A bottom rail 3 is arranged at the lower ends of these slats, and the lower end of the ladder cord 2 is connected to the bottom rail 3. At the position where the ladder code 2 of the bottom rail 3 should be attached, the bottom drum receiver 4 is fixed in the bottom rail. A projecting portion 5 is integrally formed on the upper surface of the bottom drum receiver 4, which projects on the upper surface of the bottom rail 3 and rotates in the bottom rail receiver 4 about the central axis of the bottom rail 3. The bottom drum 6 is supported so that it can. On both sides of the protruding portion 5 of the bottom drum receiver, vertical code portions 2A, 2
An insertion hole 9 for inserting B is formed, and the vertical cord portions 2A and 2B pass through the insertion hole 9 and the bottom drum receiver 4 is inserted.
It goes inside and goes around the bottom drum 6, and the lower ends thereof are integrally connected. Vertical code parts 2 before and after the ladder code
Where A and 2B pass through the insertion hole 9, the abrasion reducing member 7 is arranged at a position where the vertical code portion is in contact with the abrasion reducing member 7 to prevent the rudder code from being worn out. An elevating code 8 for raising and lowering the slats extends vertically through the slats 1 between the front and rear vertical code portions 2A, 2B of the ladder code,
The lower end of the bottom drum 3 is fixed in the protruding portion 5 of the bottom drum receiver 4 protruding above the bottom rail 3. In the above bottom rail, when the vertical code portions 2A and 2B in front of and behind the ladder code 2 are moved up and down relatively to rotate the slat 1, the ladder code 2 moves. Freely move around the bottom rail 6 to rotate the slat 1 to a completely vertical position.

[0006]

According to the present invention, the slat can be rotated to a completely vertical position to improve the light blocking effect. However, since the lifting code is arranged between the vertical code portions of the ladder code and both are attached to the bottom drum receiver, the workability of assembling the blind is good and the tape holder- Combined with the fact that is unnecessary, it is also excellent in appearance.
