Description

[Detailed Description of the Invention] (Industrial Field of Application) This invention relates to a guide device for running a shutter, which is provided in a continuous portion between the lower frame of the shutter and the lower frame of the door bag.

(Prior Art) Generally, storm shutters run between the upper and lower shutter frames attached to the outdoor side of an opening in a building, and are stored in door pockets connected to the ends of the upper and lower shutter frames. However, even if debris accumulates in the running groove of the lower frame of the shutter, it will run smoothly without being hindered by the debris, and it will come into contact with the side walls that form the groove, creating frictional resistance. In practical terms, it is required to move the shutter smoothly and lightly without any movement, and to be able to easily push the shutter perpendicular to the direction of movement inside the door pocket and store it deep inside the door pocket. The grooved door roller attached to the shutter is run on a rail protruding from the lower frame of the shutter, and the grooved door roller is moved to the shutter running surface of the flat lower frame of the shutter without a step, and the shutter is stored in the shutter. It was hot. The grooved door wheel at the connecting part between the lower frame of the shutter and the lower frame of the door pocket was developed as a device that allows smooth reciprocation between the rail of the shutter and the running surface of the shutter of the door pocket.
A guide device disclosed in Japanese Patent No.-29498 is known.

(Problems to be Solved by the Invention) This guide device prevents the outer circumferential surface of the door roller from colliding with the end surface of the bottom frame of the door bag when the grooved door roller runs, and prevents the outer circumferential surface of the door roller from colliding with the end surface of the bottom frame of the door bag. This guide device achieves the effect of allowing light and smooth running without colliding with the rails of the frame, but as shown in Fig. b and reaches the shutter running surface c of the lower frame of the door bag, so when the shutter is pulled out from the door bag and the door roller d is fitted and runs on the rail surface a from the downward slope b of the guide device, As shown in Figures 22 to 24, the outer flange e of the door roller d rides on the slope b, and as the shutter moves, the door roller d climbs the slope b and falls from the rail surface a, producing an impact sound. There was a risk that problems could occur, such as the sliding contact between the upper and lower frames of the shutter, resulting in a lack of smoothness.

Therefore, this invention was developed in view of the above-mentioned conventional problems, and was designed to solve these problems without causing the door roller of the shutter that is pulled out from the door pocket to run on the slope.
To obtain a guide device for running a shutter that can be reliably guided to a rail surface and can be smoothly opened and closed with a shutter.

(Means for solving the problem) As a means to achieve this, this invention has a lower frame of the shutter with a protruding rail on which a grooved door roller attached to the lower stile of the shutter runs, and a flat sliding surface of the shutter. A guide body is attached to the edge of the door bag bottom frame side of the door bag bottom frame, and a guide body is attached to the bottom frame of the door bag on a substrate that is flush with the sliding surface of the door bag bottom frame. Further, a guide rail is provided which is formed into a tapered slope that slopes downward from the upper surface of the rail to the shutter running surface of the door bag lower frame and becomes narrower toward the tip.

The door roller 23 can be fitted and run smoothly on the rail 14.

Note that this embodiment is based on the guide body E of the first embodiment.
However, it goes without saying that it can be implemented in other embodiments.

Further, in the above embodiment, the concave flat surface was formed so that the door roller tire guide surface was curved in an arc shape and narrowed in width with the guide rails sandwiched between them. However, the present invention is not limited to this. It may be formed to have a narrow width on one side,
The other side surface may be formed parallel to the longitudinal direction of the guide rail.

(Effect of the invention) As described above in detail regarding various embodiments,
This invention connects the lower frame of the shutter and the lower frame of the door bag at different levels, attaches a guide body having a substrate that is flush with the sliding surface of the shutter to the end of the lower frame of the shutter on the side of the lower frame of the door bag, and attaches to the guide body, Since the guide rail is provided with a tapered sloping surface that connects the top of the rail on the lower frame of the shutter to the running surface of the shutter on the lower frame of the shutter, the guide rail becomes narrower towards the tip, so the shutter can be pulled out from the shutter. Even if the outer circumferential surface of the door roller touches the guide rail, the inner circumferential surface of the outer circumferential surface of the brim is tapered and guided toward the inclined surface, so the door roller rides on this guide rail and falls, making an impact noise. The door roller can be reliably guided onto the rail and run smoothly and easily without the risk of sliding contact between the upper and lower frames of the shutter, causing problems such as creaking and lack of smoothness, while also preventing damage to the door roller. However, it has various excellent effects such as increasing durability.
