Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a cover device for the lower stile of a sash rain door, and is particularly designed to prevent dust from entering the lower stile of a sash rain door from the indoor side, and This invention relates to a lower stile cover device for satsui shutters that can suppress the flapping of the panel surface and noise during opening and closing movements.

[Prior Art] Conventionally, satsushi storm shutter devices have been installed between the shutter upper rails arranged above and below the opening on the building side, that is, on the frame side.
It is known that a plurality of sash shutters are fitted and the sash shutters are slidably opened and closed along each of these rails.

The sash shutters applied to such sash shutter devices generally have a sash frame consisting of an upper stile, a lower stile, and both left and right vertical stile, and within this sash frame, for example, a thin plate is completely inserted. Satsushi shutters are made up of shutter panels formed in the form of clapboards or clapboards.

Here, the shutter panel of this type of satsushi shutter is usually made to have a large prospective dimension for reasons such as improving the strength resistance of the shutter itself or giving a certain degree of texture. When attaching the storm door panel to the frame, a mounting structure is adopted in which it is attached closely to the inside of the front side of the sash frame. For this reason, when a shutter panel is attached to a sash frame, an unnecessary space is created inside each stile, that is, on the indoor side, resulting in a poor appearance. Since the lower end of the sloped part is placed in front of the sash frame, there is a drawback that dust etc. can easily accumulate in the space inside the lower stile on the inner side, making it unclean. Since the entire weight of the panel is placed on the lowest panel part, this part is prone to bending and deformation, and when the satsushi shutters are slid open and closed along each rail, the panel surface flaps and noise is caused by vibration. This has the disadvantage that smooth opening and closing operations cannot be performed.

[Problems to be solved by the invention] The present invention was devised in view of the above-mentioned actual situation and to eliminate the drawbacks of the conventional technology. The present invention improves the external appearance by clearing out unnecessary spaces that occur, and prevents the panel surface from flapping when the sliding shutter panel is opened and closed, while preventing bending and deformation at the lowest end of the installed storm shutter panel. It is an object of the present invention to provide a lower stile cover device for a canopy shutter that can suppress noise caused by vibration.

[Means for Solving the Problems] In order to solve the above problems, the technical means adopted by the present invention is to stretch a shutter panel bent into a sawtooth shape when viewed from the side over a shutter frame. In the satsushi shutter, a vertical surface is integrally formed at the lower end of the sloped surface located at the lowest part of the shutter panel, and the upper end of the vertical surface is abutted and supported by the inner wall of the front side rising piece of the lower stile, and the above-mentioned A cover plate is provided to cover from above the space formed between the rising piece on the back side of the lower stile facing the vertical plane, and the front and rear edges of the cover plate are folded downward in the shape of both legs, and the front edge side is inclined. It is characterized in that it is fitted in a state where it is pressed and supported by the surface.

[Operation of the invention] Therefore, according to the invention, it is possible to improve the external appearance by clearing out the unnecessary space that occurs on the indoor side, and also to reduce the bending at the bottom end of the installed storm door panel. It is possible to prevent deformation and suppress noise caused by flapping of the panel surface and vibration during sliding opening/closing.

[Example] The configuration of the present invention will be described in detail with reference to an example shown in the drawings.

In FIGS. 1 and 2, 1 is a house frame, and a basic sash frame 3 disposed in an opening 2 of the house frame 1 has an upper frame that constitutes a shutter guide frame 4. A shutter upper rail 5, a shutter lower rail 6, and a door stop frame 7, which serves as a vertical frame, are attached to one end thereof, and upper and lower door bag members 8, 9 are provided at the other end. A plurality of sash shutters 10 are fitted between the upper shutter rail 5 and lower shutter rail 6 so as to be slidable and openable along each rail.

The above-mentioned sash shutter 10 is constructed by bending a thin plate within a slat frame 11 consisting of an upper stile 12, a lower stile 13, and left and right vertical stile 14, 15, so that inclined surfaces 16a, 16
a... and step portions 16b, 16b..., and a vertical surface 16c is integrally formed at the lower end of the lowermost inclined surface 16a. A back side rising piece 1 is stretched in close contact with the inner sides of 12a and 13a, and faces the front side rising pieces 12a and 13a.
2b and 13b, a cover plate 17, which will be described later, is inserted to hold the shutter panel 16 in the shutter frame 11.

The cover plate 17 includes a horizontal substrate portion 17a,
A front edge side 17b and a back side folded piece 17c are bent downward from the front and rear edges of this base plate portion 17a to form both legs.
and the leading edge side 1.
7b is formed shorter than the rear back side folded piece 17c, and extends along the space 18 formed between the inner surface of the storm door panel 16 and the inner side of the back side rising piece 13b of the lower stile 13. It is configured to be fitted over the entire length.

In the configuration as described above, in order to attach the shutter panel 16 to the lower stile 13 of the shutter sash frame 11, first, the shutter panel 16 is brought into close contact with the front rising pieces 12a, 13a of the upper and lower frames 12, 13. It is placed within the shutter frame 11. At this time, the vertical surface 16c of the shutter panel 16 comes into contact with the inside of the front rising piece 13a of the lower stile 13, and the vertical surface 16c and the lower stile 1
A space 18 is formed between the rear side rising piece 13b of 3. Next, the cover plate 17 is attached to the front edge side 17.
With the front edge side 17b facing downward and the back side folding piece 17c, push down the shutter panel 16 and the cover plate 17 into the space 18 against their own elasticity while slidingly contacting the front edge side 17b with the back surface of the inclined surface 16a. When inserted, the back side folded piece 17c is closely fitted to the back side rising piece 13b of the lower stile 13, and the front edge side 1
7b is positioned and locked on the back surface above the sloped end portion of the sloped surface 16a. In this state, cover plate 1
The base plate portion 17a of No. 7 has an elastic force maintained between the back side rising piece 13b and the inclined surface 16a, and is located above and below the front and back surface area from the inclined surface 16a of the shutter panel 16 to the vertical surface 16c. Bending stress in the counterclockwise direction when viewed from the side is generated and maintained by the front edge side 17b of the cover plate 17 and the front side rising piece 13a of the lower stile 13, which face each other. Also, the panel surface is prevented from flapping when the satsui rain shutters are slid open and closed along each rail.

[Effects of the invention] In short, the present invention provides a sash shutter in which a sash panel is bent in a sawtooth shape when viewed from the side and stretched over a sash frame, and the sloping surface located at the lowest part of the sash panel. A vertical surface is integrally formed at the lower end of the frame, and the upper end of the vertical surface is abutted against and supported by the inner wall of the front rising piece of the lower stile, and between it and the rear rising piece of the lower stile facing the vertical surface. A cover plate is provided to cover the formed space from above, and the cover plate is fitted with its front and rear edges folded downward in the shape of both legs and its front edge side pressed against the inclined surface. With the extremely simple operation of simply pushing the cover plate into the space formed in the lower stile, without the need for fixing or fastening, the elasticity of the sloped surface of the storm door panel and the elasticity of the cover plate itself allows
The storm door panel can be easily and easily attached to the sash frame, the appearance of the inside part of the lower stile of the sash frame can be improved, and the intrusion of dust etc. into the space can be effectively prevented. After installing a storm door panel, bending stress is generated and maintained on the front and back surfaces of the storm door panel, from the sloped surface to the vertical surface, so there is no noise caused by flapping of the panel surface and vibration as the shutter opens and closes. This has extremely useful practical effects, such as suppressing as much as possible and allowing the shutters to open and close smoothly.
