Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a fitting that is fitted into a rail such as a shutter.

[Conventional technology]

There is a fitting in which an engaging piece is provided on the upper and lower frames and the engaging piece is engaged with a hook-shaped protrusion provided along the entire length of the rail to prevent the engaging piece from being separated from the rail. FIG. 6 shows a shutter A which is an example of a conventional fitting of this type. The shutter A shown in the same figure has a face plate 5 attached to a door frame composed of an upper frame 1, a lower frame 2, and left and right vertical frames 3 and 4, and is a member extending over the entire width of each of the upper frame 1 and the lower frame 2. Stops 6 and 7 are integrally provided. As is apparent from FIG. 7, the locking piece 6 of the upper frame 1 is projected to the outside of the upper frame 1 in an inverted L shape, while the locking piece 7 of the lower frame 2 is outside of the lower frame 2. H-shaped projections 9 are provided on the upper rail 8 and vertical parts 6a and 7a of the locking pieces 6 and 7 are protruded in an L shape, and a hook-shaped projection 11 is provided on the lower rail 10. Are engaged separately. In such a conventional shutter A, the vertical rails 6a, 7a shown in FIG. 7 and the inner side surface of the upper frame 1 or the lower frame 2 are separated from each other by a distance b between them.
Alternatively, it is larger than the groove width dimension a of the lower rail 10.

[Problems to be solved by the device]

However, in the conventional shutter A, since the mutual distance b is larger than the groove width dimension a, the upper rail 8 and the lower rail 10 are directly connected to each other.
There was a problem that I could not fit in.

Therefore, conventionally, as shown in FIG. 8, a rain door A was put in a door bag 12 provided at the end of the rail with the cover 12a removed, and the rain door A was fitted into the rail from the door bag 12. However, in the conventional shutter door A, the locking pieces 6, 7 are provided over the entire width, and when the locking pieces 6, 7 of the shutter door A are not straight with respect to the ridges 9, 11. The locking pieces 6 and 7 are caught by the ridges 9 and 11 and cannot be fitted into the rail smoothly. Therefore, before fitting the shutter A from the door pocket 12 to the rail, the engaging pieces 6 and 7 must be aligned so as to be straight with respect to the ridges 9 and 11, and fitting on the rail is troublesome. There was a problem. Even when the shutter A is stored in the door pocket through the opening as shown in FIG.
Since the locking pieces 6 and 7 had to be straight with respect to the ridges 9 and 11 until they were stored in, the rain door A that had been stored in the door pocket in advance obstructed easily. There is also the problem that it cannot be stored.

This invention has been made in view of the above problems, and by a simple improvement of the locking piece attached to the frame side, it is not necessary to use a door pocket, and it can be easily fitted directly on the rail. An object of the present invention is to provide fittings such as shutters that can ensure smooth movement without rattling after being fitted and have a high anti-slip effect.

[Means for Solving the Problems] In order to achieve the above object, a fitting such as a shutter according to the present invention has an upper rail or a lower rail that guides the movement of the fitting.
The lowering portion or the rising portion bent downward or upward from the outer end edge of the rail, the horizontal extending portion protruding inward from the end of the lowering portion or the rising portion, and the horizontal extending portion An engaged projecting piece consisting of a vertical portion that projects upward or downward from the inner end is attached, while the upper frame or the lower frame of the fitting is a horizontal part that is fitted into the groove bottom and this horizontal part. A rising or falling portion bent upward or downward from one end edge of the, and an upper end of the rising portion or a lower end of the falling portion or an extending portion projecting outward and downward from the tip of the extending portion or An engaging piece having an engaging part that is engageable with and disengageable from the rail-side protruding piece is attached to the horizontal part of the engaging piece. And the top of the screw hole formed at the location that is located inward of the face plate of the fitting. Via a threaded member that is inserted into an elongated hole formed in the groove bottom of the upper or lower frame in the inward and outward direction and screwed into the screw hole, the engaged projection on the rail side of the engaging portion. And a state in which it is held so as to be displaceable vertically and inward and outward so as to allow engagement and disengagement with respect to the rail, and the upper frame or the lower frame is fixed by engaging the engaging portion with the engaged projection on the rail side. It is configured to be switchable to the state.

[Operation] According to the present invention, the engagement piece attached to the upper or lower frame side is held so as to be displaceable in the up-down direction and the inward / outward direction. It is possible to directly fit the fitting to the rail with the part attached to the upper or lower frame side. In addition, after fitting into the rail, with the engaging portion of the locking piece engaged with the engaged projection on the rail side, the screw member is attached to the locking piece from the inner side of the face plate of the fitting. By screwing into the screw hole formed in the horizontal portion and fixing the locking piece to the upper frame or the lower frame, the fitting is in a state in which the movement of the fitting is restricted in the vertical direction and in the inward / outward direction with respect to the rail. . This will prevent the rail from coming off, and
There is little swinging in and out, allowing smooth movement without rattling.

[Advantage of Invention] As described above, according to this invention, when attaching fittings such as shutters to the rail for the first time, the locking pieces attached to the upper and lower frames can be displaced vertically and inward and outward. By holding the locking piece so that it does not get caught on the engaged projection on the rail side, it is possible to directly fit or remove the fitting with the locking piece attached. Becomes Therefore, unlike the prior art, it does not require any troublesome work such as fitting and removing using the door pocket, and can be fitted and removed on the rail very easily and efficiently. Moreover, after fitting into the rail, the fitting portion of the locking piece is engaged with the engaged projection piece on the rail side and fixed to the upper frame or the lower frame via the screw member to thereby fix the fitting. It is possible to regulate the movement of the rail in both the up and down direction and the inward and outward directions. Therefore, it is possible to reliably prevent the rail from being disengaged, and also to ensure smooth movement without rattling with little runout in the inward and outward directions. it can. Further, since it is not necessary to provide the locking piece over the entire width of the fitting, it is possible to reduce the cost by saving the constituent material of the locking piece. Further, by displacing the locking piece inward with respect to the upper and lower frames, it is very convenient for cleaning dust collected on the rail.
