Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevating guide structure for a slat curtain in a shutter device arranged in a window or the like which is an opening of a building such as a house.

[0002]

2. Description of the Related Art Generally, a slat curtain, which constitutes a shutter device disposed in a window which is an opening portion of a building such as a house, generally has long strip-shaped slats that are vertically connected to each other to form an upper edge of a window. The base end side of this slat curtain is attached to the winding shaft attached via the bracket fixed in the shutter box arranged in
It can be wound around a winding shaft, and the slat curtain is taken in and out from the swallow part formed on the bottom of the shutter box, and the window is opened and closed. Then, guide rails having a U-shaped cross section are provided on both left and right sides of the window portion so as to communicate with the swallow portion so as to guide the slat curtain up and down. The guided slat curtain is fitted with both end edges thereof with the groove bottom portion of the guide rail leaving an interval of 10 mm to 25 mm, and has an interval of the same dimension as the bracket in the shutter box. It is designed to be wound around a winding shaft.

In the slat curtain constructed as described above, the slat may shift laterally at the connecting portion between the slats while the slat curtain is repeatedly moved up and down. To prevent this, both ends of the slat curtain are prevented. In order to prevent the slats from slipping off from each other, caulking or metal scraps were provided.

[0004]

However, in the above-mentioned conventional structure, twisting of the winding shaft, deflection of the slats, warpage, etc. cause lateral displacement of the slats and lateral displacement of the entire slat curtain. In particular, when the slat curtain descends, the end of the slat curtain hits the slat swallowing opening at the upper end of the guide rail, and the slat does not descend, or the slat curtain comes into contact with the side surface of the bracket to cause frictional noise. This is because the structure of the conventional slat curtain described above is to prevent lateral slippage between slats, and if the entire slat curtain deviates from its elevating orbit, it will damage the caulking and end hardware attached to the end of the slat curtain. Therefore, there is a problem that the life of the slat curtain is shortened.

In addition to the above-mentioned problems, the side surface of the bracket that supports the winding shaft may be scraped off as the laterally displaced slat curtain is repeatedly moved up and down.
As a result, the opening and closing operation of the slat curtain may be hindered, and in the worst case, the slat curtain may be dropped.

Therefore, in order to solve the above problems, the present invention prevents the lateral displacement of slats and the lateral displacement of the entire slat curtain when the slat curtain moves up and down,
It is an object of the present invention to provide a simple structure for raising and lowering a slat curtain, in which both edges of the slat curtain do not directly contact the guide rails.

The correction members 6 are composed of a pair of left and right members, and the distance between the correction members 6 is set to be slightly larger than the width of the slat curtain 3.

Therefore, in the guide structure constructed as described above, as shown in FIG. 2, even if the slats 3a forming the slat curtain 3 are laterally displaced during the descent, the slats 3a move downward while contacting the inclined surface 6c. Therefore, it becomes possible to smoothly move into the guide rail 2, and the slat 3a passes through the regular position without hitting the swallowing port 5. In addition, even when the slat 3a is moved upward, the lower slanted surface 6c prevents the lateral displacement of the slat 3a and corrects the winding state.

Here, the shape of the correction member 6 is not limited to the above-described shape as long as it has an inclined surface that is inclined downward to the right and upward to the right, and is inclined downward. It may be formed of a curved surface.

In the above-described embodiment, the correction member 6 has a substantially cylindrical shape with a tapered tip, but the shape is not limited to this.

That is, the correction member may be a substantially egg-shaped swelling-molding member, or the correction member 6 may be formed in a semicylindrical shape. In the case of this straightening member having a semi-cylindrical shape, it is arranged with the horizontal direction as the longitudinal direction, and at least the slat curtain 3 is at the bottom of the swallowing opening 5 of the guide rail 2, that is, the contact portion between the swallowing opening 5 and the guide rail main body. , The center point P1 of the groove S, the orbit line L1 of the slat curtain 3 in the initial winding stage of the slat curtain 3, and the slat curtain 3 in the final winding stage.

Further, in each of the above-mentioned embodiments, the example in which the shape of the correction member 6 is projected with respect to the bracket 4 has been described, but the center is formed with a concave curved surface, and both sides thereof are formed with a pair of convex curved surfaces. It may be formed in a substantially drum shape (see FIG. 4).

According to this correction member, the convex curved surface portions on both sides are located in the thickness direction of the slat curtain 3 while being attached to the bracket 4. As a result, not only lateral displacement of the slats 3a but also displacement in the front-back direction can be corrected.

In the above-mentioned substantially drum-shaped correction member, the central concave portion is formed by a curved surface. However, as shown in FIG. 4, a vertical flat surface 7a is formed, and convex portions are formed on both sides of this flat surface 7a. The correction member 7 may be configured to form the curved surface 7b.

A substantially drum-shaped correction member 9 having a concave curved surface 9b in the center and a pair of ridges 9c on both sides may be a structure slidable in the horizontal direction.

According to this correction member 9, the concave curved surface 9b portion which is in sliding contact with the end edge of the slat curtain 3 is a trajectory which fluctuates in the front-back direction due to the elevation of the slat curtain 3, that is, the winding radius of the slat curtain 3. Corresponding to the change, it is movable in the direction (front-back direction) orthogonal to the ascending / descending direction.

At both ends of the guide beam 10, stoppers 11 for restricting the sliding movement of the correction member 9 are provided. If the stopper 11 is removable, it can be replaced even if the correction member 9 is damaged or worn.

Further, the guide beam 10 may be formed integrally with the bracket 4, or may be a structure separate from the bracket 4 and attached by a fixing means or the like. In the case of this separate structure, It can also be attached to existing shutter devices.
