Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a horizontally drawn blind having ventilation and lighting functions.

[Problems to be solved by the prior art and the invention]

Generally, horizontal sliding blinds having ventilation and lighting functions are known in which slats are fixed to links, and the angle of the slats can be changed by extending the links. However, since the slats are fixed to the rotating link, there is a limit to the angle of the slats, and there are problems in that the amount of ventilation is not sufficient and the opening direction of the slats is always oriented in one direction.

[Means to solve the problem]

The present invention was devised in view of the above-mentioned circumstances with the aim of providing a horizontal blind that can eliminate these drawbacks.
One link of two sets of links, which are connected in synchrony with each other by half a pitch, is attached to one end on the movable body side and the other end on the fixed end side, so that it expands and contracts as the movable body moves. Configure as you like,
Further, the central shaft of one link is constituted by an operating shaft embedded in the slat, and a pinion is integrally attached to the operating shaft, and the pinion is fitted inside the end shaft of the other link. When the rack member is attached, the rotation angle of the slat can be changed by lateral movement of the rack member as the movable body moves, and the pinion meshes with the rack teeth provided on the rack member and rotates forward and backward. This feature is characterized in that it is configured to allow selection.

According to the present invention, with this configuration, the opening direction of the slats can be freely changed in accordance with the expansion and contraction of the link, making it possible to have a wide range of variation.

〔Example〕

Next, embodiments of the present invention will be described based on the drawings.

In the drawing, reference numeral 1 denotes rails arranged above and below a slat 2 serving as a rain door, and within the rail 1, 2 pulleys 3, 3 with ropes R suspended from the left and right are arranged.
The rope R is attached on one side to a drive plate 6 provided with rolls 5 that roll along the rail surfaces 4, 4 in the rail, and the drive plate 6 is moved by the rope R. In the guide groove 7 provided in the rail 1, there is a bearing member 9 that supports the operating shaft 8 of the slat 2.
and the roller 1 from the bearing member 9
0 supports the slat 2 in a rolling manner. At the upper end of the operating shaft 8, there is a recess 1 that engages with a projection 11a provided on a rack member 11, which will be described later.
A pinion 12 provided with the pinion 2a is fixed, and the rotation of the pinion 12 causes the slat 2 to rotate.

In addition, there are two links 13 and 14 within the rail 1.
are arranged one above the other with their ends pinned so as to be shifted by half a pitch and synchronized, one upper link 13 being pinned to the rack 11 and the other lower link 14
is rotatably fitted on the slat operating shaft 8. A pinion 1 is provided inside the rack member 11 to stop the rotation of the slat for a certain period from the time of closing start.
The racks 11b and 11 are provided with a convex portion 11a that engages with the concave portion 12a of No. 2, and the racks 11b and 11 are provided so that the pinion 12 that engages with the convex portion 11a rotates approximately 45 degrees and approximately 135 degrees in the opposite direction.
c.

In the embodiment of the present invention, when the rope R is driven and moved by an appropriate means, the links 13 and 14, which are pinned on one side to the drive plate 6 and on the other to the fixed plate on the pulley side, are moved by the movement of the drive plate 6. They expand and contract and move in sync. Before this movement, the convex portion 11 of the rack member 11
a and the recess 12a of the pinion 12 mesh with each other, and the slat 2 is in an open state without rotating as shown in FIG.
When the rack 14 is extended, the slats 2 do not rotate and remain open with the concave and convex portions 12a and 11a remaining in mesh with each other, but the pinion 12 remains open when the first rack 1 is opened.
When the slat 2 meshes with the slat 1b and moves, the slat 2 rotates by approximately 45 degrees due to the rotation of the pinion 12 (see Fig. 4B).
When the drive plate 6 is further moved, the pinion 12 now engages with the rack 11c and rotates approximately 135 degrees in the opposite direction, so that the slat is in the state shown in FIG. 4C. FIG. 4D shows the slat when it is fully closed.

When the drive plate 6 is moved in this way, the two links connected to it expand and contract, causing the slats to rotate on both sides, providing sufficient light and ventilation.Moreover, the amount of ventilation and light can be freely selected, and the slats are rotated to both sides. It can also be used as

[Function and effect]

In summary, since the present invention is constructed as described above, the pinion of the operating shaft provided with the slat is moved within the rack member by the expansion and contraction movements of the two links, and changes are made by the meshing of the racks of the rack members. Lighting and ventilation directions can be freely changed in a highly flexible state, providing sufficient ventilation and lighting, and can also serve as a sunshade.
