Description

[Detailed description of the device]

[0001]

[Industrial application]

 This invention relates to a guide rail for a shutter.

In this specification, with respect to the front-rear relationship, the outer wall of the building to which the shutter is attached is a reference, the front side is the front, and the opposite side is the rear.

[0003]

[Prior Art]

 The conventional channel-shaped shutter guide rail is integrally formed.

[0004]

[Problems to be solved by the device]

 In order for the slat to move up and down smoothly in the shutter, there must be a certain gap between the bottom wall of the guide rail and the left and right edges of the slat. It was difficult to check because it was necessary to look into the back of the guide rail through the narrow gap in the rail opening, which was a troublesome task.

Further, for example, when one of the slats constituting the slat is damaged, the entire slat is once wound on the winding shaft, and then the winding shaft is removed and placed on the ground, and the broken slat is broken there. I pulled out one piece and replaced it with a new one. This task was tedious and inefficient.

An object of the present invention is to provide a guide rail for a shutter in which shutter installation work can be performed easily and reliably, and replacement work of a damaged slat piece is easy and efficient.

[0007]

[Means for Solving the Problems]

 The shutter guide rail according to the present invention is a channel-shaped shutter guide rail composed of a front wall, a rear wall and a bottom wall, wherein the front wall is detachably attached to the bottom wall. ..

[0008]

[Action]

 Since the front wall of the shutter guide rail according to the present invention is removably attached to the bottom wall, the bottom wall of the guide rail and the left and right edges of the slats are removed with the front wall removed. While visually confirming that there are predetermined gaps between them, attach slats and then attach the front wall.

Further, for example, when one of the slats constituting the slat is damaged, the front wall of the guide rail is removed, the damaged slat is pulled out to a position where it is easy to work, and is replaced with a new one.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

The shutter (1) of FIGS. 1 to 5 is a window shutter attached to the outer wall (A) of the building, and has a plurality of slat pieces (2a) whose hollow portion is filled with a heat insulating material (25). The slats (2) connected to each other, the pair of left and right channel-shaped guide rails (3), the shutter case (4), the winding shaft (5), and the winding shaft (5) through the bearings. With a supported bracket (7).

The guide rail (3) is made of an extruded aluminum material, and includes a front wall (11), a rear wall (12) and a bottom wall (13). The rear wall (12) and the bottom wall (13) are integrally formed, but the front wall (11) is a separate member from them, and the front wall (11) is the bottom wall (13). It is detachably attached to.

As shown in FIG. 2, the front wall (11) of the bottom wall (13) of the guide rail (3) has a U-shaped fitting recess (14) at its opening at the side edge. The bottom wall (13) of the front wall (11) is provided with a U-shaped fitting projection (15) on the side edge of the front wall (11) with its opening facing rearward. It is provided in a protruding shape. The fitting concave portion (14) and the fitting convex portion (15) both have some elasticity. There are hook-shaped engaging inner protrusions (16) on the inner surfaces of both side walls of the mating recess (14), and hook-shaped outer engaging protrusions (17) on the outer surfaces of both side walls of the mating protrusion (15). ) Are provided respectively.

Then, the fitting convex portion (15) of the front wall (11) is fitted into the fitting concave portion (14) of the bottom wall (13), and the engaging outer protruding portion (17) and the engaging inner protruding portion (17). The front wall (11) is attached to the bottom wall (13) by engaging the portion (16). The engagement between the outer protrusion (17) and the inner protrusion (16) is such that the front wall (11) is disengaged by pulling it strongly toward you.

A vertical frame (6) is fixed to the outer wall (A) of the building by a screw (20), and the guide rail (3) is fixed to the outer wall (A) of the building through the vertical frame (6). Has been done. The rear wall (12) of the guide rail (3) is provided with a mounting wall (12a) fixed to the vertical frame (6) with screws (21).

In addition, the opening of the guide rail (3) has a groove with a substantially U-shaped cross section in which both edges are bent inward at the edges of the front wall (11) and the rear wall (12). (18) is provided, and the mohair (19) is fitted into the groove (18) to close the gap between the slat (2) and the opening of the guide rail (3).

As shown in FIG. 3, each slat piece (2a) is provided at its upper portion with an engaging portion (22) having an inverted J-shaped cross section over the entire length, and at the lower portion thereof is an inverted portion. An inwardly projecting engagement portion (24) that engages with the J-shaped engagement portion (22) is provided over the entire length thereof with an engagement portion storage portion (23) having a substantially U-shaped cross section with a downward opening. There is. Then, the inverted J-shaped engaging portion (22) of the lower slat piece (2a) is fitted into the engaging portion storage portion (23) of the upper slat piece (2a), and the required number of slat pieces (2a) are obtained. Connected to form slats (2).

To attach the shutter (1) to the window, proceed as follows (see FIG. 4).

First, on the ground, a pair of left and right vertical frames (6), a lintel (not shown) and a lower frame (8) are assembled to form a frame, and on this frame, the rear wall of the guide rail (3) ( Install 12) and bottom wall (13), take-up shaft (5), bracket (7) and slat (2). Then, each vertical frame (6) is fixed to the outer wall (A) of the building, and then the front wall (11) of the guide rail (3) is attached to the bottom wall (13).

When fixing each vertical frame (6) to the outer wall (A) of the building, as shown in FIG. 5, there is no front wall (11) of the guide rail (3) and the slats (2) are attached to the front and rear. It is easy to move left and right. Therefore, visually check whether the slats (2) are distorted and moved up and down, and whether the left and right edges of the slats (2) are touching the bottom wall (13) of the guide rail (3). Install so that (6) is vertical and the lintel and lower frame (8) are horizontal. In this case, the walls and window frames of the building (A) are not always exactly attached, so the vertical frame (6), the lintel and the lower frame (8 ) It is important to have its own horizontal and vertical.

For example, if one of the slat pieces (2a) is damaged during use, first remove the front wall (11) and move the slat (2) in the state shown in FIG. Then, pull out the broken slat piece (2a) and replace it with a new one.

In the above embodiment, the fitting concave portion (14) and the fitting convex portion (15) are both U-shaped, but not limited to this, and may be arcuate or the like. Further, the shapes of the engaging portions (16) and (17) provided in the fitting concave portion (14) and the fitting convex portion (15) can be changed as appropriate, and the engaging portions (16) (17) can be omitted. Then, the fitting concave portion (14) and the fitting convex portion (15) may be engaged with each other by the elastic force.

[0023]

[Effect of the device]

 According to the shutter guide rail of the present invention, with the front wall removed, the slats can be visually checked to confirm that there is a predetermined gap between the bottom wall of the guide rail and the left and right edges of the slats. The shutter can be installed easily and surely because it can be installed and then the front wall can be installed. In addition, if any of the slats that make up the slat is damaged, the damaged slat can be replaced with a new one simply by removing the front wall. Replacement work is easy and efficient.
