Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a shutter guide member that guides a shutter (end portion) moving within a guide rail.

(Prior Art) Shutters are widely used in stores, warehouses, etc. as fittings to protect against fire, wind and rain, theft, smoke, etc. There are many types of shutters, including heavy-duty shutters, lightweight shutters, high-speed shutters, and electric shutters, and there are also various construction methods, such as pre-installation methods and post-installation methods.

By the way, as shown in FIG. 1, conventional shutters are constructed so that the shutter 2 simply slides or moves within a guide rail 1, and a spacer is interposed between the guide rail 1 and the shutter 2. There are no such devices that are equipped with a sealant or a sealant.

Therefore, there were problems such as play occurring between the guide rail 1 and the shutter 2 and a squeak sound occurring when the shutter 2 was moved. Furthermore, since the seal between the guide rail 1 and the shutter 2 was not completely sealed, rain and the like often entered the room.

(Purpose of the invention) This invention was devised in view of the above-mentioned problems, and eliminates the occurrence of rattling and squeaks by eliminating the gap between the guide rail and the shutter and completely sealing it. It is an object of the present invention to provide a guide member for a shutter that can prevent rainwater and the like from entering indoors and can move the shutter more smoothly.

(Structure of the invention) This invention arranges guide members made of long elastic thin plates in a groove of a guide rail with a lip groove cross section provided on both sides of an opening so as to face each other along the side walls of the groove. The guide member has a plurality of wave-shaped bent lines in the longitudinal direction, and both side edges of the shutter slide into narrow gaps between the opposing protrusions of the bent lines of the guide member, and the guide rail is It is characterized by being able to move up and down within the groove.

The guide member is preferably made of high-density polyethylene, plastic, hard rubber, or the like.

(Example) This invention will be described below based on an example shown in the drawings.

FIG. 2 is a cross-sectional view showing an embodiment of this invention, where 1 is a guide rail, 2 is a shutter,
3 is a guide member.

The guide rails 1 are provided on both sides of the opening, have a lip groove shape in cross section, and have guide members 3 installed therein for guiding the side edges of the shutter 2. The guide member 3 is made of a long elastic thin plate, has a plurality of wave-shaped bent strips in its longitudinal direction, and is arranged opposite to each other along the groove side wall of the guide rail 1.

The bending strips of the opposing elastic members of the guide member 3 have protruding strips facing each other and the gap is narrowed, so that the shutter 2
When the shutter 2 is guided by the guide rail 1 and moves up and down, both side edges of the shutter 2 come into sliding contact with the guide member 3 at the locations where the distance is narrowed.

In the embodiment shown in FIG. 2, the oppositely mounted elastic thin plates of the guide member 3 are bent and connected in an arc shape at the bottom of the groove of the guide rail 1, and are substantially formed of one thin plate. One of the bent strips of the elastic thin plate is located at the opening of the lip groove of the guide rail 1, and the edge of the bent strip holds the lip opening edge of the groove to fix the elastic thin plate in the groove opening. Further, the arcuate bent strip of the elastic thin plate is recessed in the center and is in sliding contact with the edge of the shutter 2. In this way,
The shutter 2 is arranged so that the end of the shutter 2 is covered with a guide member 3 inside the guide rail 1,
It is attached so as to be in sliding contact with the bent strip of the guide member 3 and to close the gap between the shutter and the guide rail.

Therefore, it is possible to prevent rainwater and the like from entering the room, and the occurrence of rust and the like can be prevented. Further, the guide member 3 has elasticity and is designed to contract slightly inward when the shutter 2 is raised, so that the shutter 2 is always supported so as to be sandwiched between the guide members. Therefore, when the shutter 2 is moved, rattling or squeaks are not generated, and the shutter 2 can be moved more smoothly. Further, if the guide member 3 is molded from high-density polyethylene, plastic, hard rubber, etc., it is easy to manufacture and is almost maintenance-free after installation.

FIG. 3 is a cross-sectional view showing a second embodiment of this invention.

The guide member 3 shown in FIG. 2 was a one-piece type in which elastic thin plates were connected at the bottom of the guide rail groove, but the guide member 3 shown in this figure is a two-piece type. That is, the elastic thin plate of the guide member 3 is divided into two pieces, and the end part is arranged with the center line in the width direction of the guide rail 2 symmetrical, so that it slides on the end part of the shutter 2, and It closes the gap with shutter 2. This guide member 3 has elasticity so as to return inward, and the shutter 2 moving within the guide rail 1 is controlled by the two thin plates of the guide member 3 between the end of the thin plate of the guide member 3 and the end of the shutter. and the narrowed portions of the bent strips, which are pressed together in a sandwiching manner. The guide member 3 of this third embodiment is used when there is a small gap between the shutter 2 and the inner wall of the guide member 3, etc.
This is particularly effective when the one-piece type guide member 3 shown in the figure cannot be used.

FIG. 4 is a cross-sectional view showing a third embodiment of this invention.

The illustrated guide member 7 is different from the two embodiments described above, and is supported by the inner wall of the guide rail 1 using a bent strip, and the entire guide member 7 is interposed within the guide rail 1. The end portion 8 is brought into contact with the shutter insertion port side of the inner wall of the guide rail 1, thereby preventing rainwater and the like from entering the room. At this time, if the gap between the shutter 2 and the shutter 2 is reduced by bending the open end of the lip of the guide rail 1 inward, the shutter 2 can contact the end of the guide rail 1 since it is supported by the guide member 7. There is no need to interpose a guide member in the gap.

Although three embodiments have been described above, various other shapes can be used, and the most suitable shape can be used depending on the usage condition.

(Effects of the invention) The structure of this invention is as described above, and according to this invention, the following effects can be obtained.

Prevents squeaks and rattles that occur when the shutter is moved.

There is no play between the guide rail and the shutter, and the shutter can be moved smoothly.

It can prevent rainwater etc. from entering indoors.
