[Prior Art] Conventionally, when fixing a bracket or the like to an existing curtain rail, a plate-shaped fastener wider than the groove width of the curtain rail is inserted from the end of the curtain rail to a desired position within the rail. Brackets and the like were fixed to this fastener, but it had the disadvantage that the work was complicated.

For this reason, the present applicant filed an application for a "stopper for a partition rail" that can be easily inserted and removed at a desired position on a curtain rail (Kokoku Kokoku Sho 57-18528). However, the stopper for the partition rail needs to be specially manufactured according to the shape of the curtain rail to be attached, and cannot be applied to various curtain rails, resulting in a drawback of poor versatility.

[Purpose of the invention] The present invention solves the above-mentioned drawbacks, and can be easily inserted and removed at the desired position of the curtain rail.
Another object of the present invention is to provide a highly versatile curtain rail fastening device that can be applied to various types of curtain rails.

[Structure of the invention] The invention has a screw hole drilled in the center, hanging pieces at the front and back, the front and rear widths are smaller than the groove width of the curtain rail, and the left and right widths are larger than the groove width of the curtain rail. A nut plate with a hole diameter larger than the screw diameter is drilled, and an upright piece is provided protruding from the oblique side of the through hole, and the front and rear width is smaller than the groove width of the curtain rail, and the left and right width is the same as the curtain rail. The screw is provided with a board formed larger than the groove width of the rail, and a screw that passes through the receiving hole of the fixture to be attached and the through hole of the board and is screwed into the screw hole of the nut plate disposed above it. Insert it into the curtain rail groove by screwing it into the screw hole of the nut plate through the receiving hole of the fastening tool and the through hole of the board, then tighten the screw and turn the nut plate about 1/4 turn to tighten the board. After hitting the upright piece and locking it, tighten the screw in that state so that the tip of the hanging piece of the nut plate comes into contact with the inner bottom surface of the rail to fix the fixture, and then loosen the screw. It is characterized in that the nut plate is reversed so that its hanging piece comes into contact with the upright side of the board, and the nut board and the board are taken out from the groove of the curtain rail.

[Example] Next, an example of the present invention will be described in detail based on the drawings.

As shown in FIG. 1, 10 is a curtain rail, and a groove 11 is formed in the bottom surface in the longitudinal direction. In this example, the curtain rail 10 is a C-shaped rail. Numerals 12 and 12' are nut plates, each having a screw hole 13 and 13' in the center thereof, and hanging pieces 14, 14, 14' and 14' at the front and rear. The front and back width a of this nut plate 12 is smaller than the groove width w of the curtain rail 10 even if the thickness of the upright piece 18 of the base plate 16, which will be described later, is added, and its left and right width b is larger than the groove width w of the curtain rail 10. It is formed.

Reference numeral 16 denotes a board with screws 22, 22', which will be described later.
Through-holes 17, 17' having a larger diameter are bored, and upright pieces 18, 18' project from the oblique sides of these through-holes 17, 17', respectively. The front-rear width c of the substrate 16 is smaller than the groove width w of the curtain rail 10, and the left-right width d thereof is larger than the groove width w of the curtain rail 10.

Reference numeral 20 denotes a bracket which is a fastening device, and receiving holes 21 and 21' having a diameter larger than that of the screws 22 and 22' are bored corresponding to the spacing between the through holes 17 and 17'. This bracket 20 is a curtain rail 10
It has a wider upper surface than the groove 11 of.

The screws 22, 22' are attached to the bracket 20, respectively.
receiving holes 21, 21' and through holes 17 of the substrate 16,
Nut plate 1 passing through 17' and disposed above it
2, 12' into screw holes 13, 13'.

A fastening device with such a configuration is attached to the curtain rail 1.
0, first insert the screws 22, 22' into the nut plates 12, 1 through the receiving holes 21, 21' of the bracket 20 and the through holes 17, 17' of the base plate 16.
Screw into the screw holes 13, 13' of 2' and tighten the nut plate 1.
2 and 12' are temporarily fixed, and in this state, the nut plates 12 and 12' and the base plate 16 are inserted into the curtain rail groove 11.

Thereafter, as shown in FIGS. 2 and 3, when the screw 22' is first tightened with a screwdriver (not shown), the nut plate 13' rotates 1/4 and its hanging piece 14' attaches to the board 1.
The nut plate 13' abuts against the upright piece 18' of No. 6 and is locked in a state perpendicular to the base plate 16. When the screw 22' is further tightened in this state, the hanging piece 1 of the nut plate 13' is tightened as shown by the dashed line in FIG.
Each end of the bracket 4' comes into contact with the inner bottom surface of the curtain rail 10, and the top surface of the bracket 20 comes into contact with the outer bottom surface of the curtain rail 10, so that the bracket 2
0 is fixed. By tightening the screws 22 in the same manner, the bracket 20 is attached to the curtain rail 10.
is fixed even more securely.

Next, when removing the bracket 20 from the curtain rail 10, as shown in FIG. 2 and FIG. comes into contact with. Similarly, if the screw 22' is loosened, the hanging piece 14' of the nut plate 12' will come into contact with the upright side 18' of the base plate 16, and the nut plates 12, 12' will become parallel to the groove 11. , 12', the base plate 16 and the bracket 20 can be removed from the curtain rail 10 with the screws 22, 22' attached.

Although the above example shows an example in which there are two nut plates, as shown in FIG. The width e of the upward pieces 23, 23 may be smaller than the groove width w of the curtain rail 10.

In this case, as shown in FIG.
