Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mounting nut that is used when fixing an electrical appliance or the like to a rail or other groove and can be immediately fitted into a desired position in the groove. The conventionally known mounting nut has a rectangular planar plate whose long side is made larger than the groove width of the rail or other (hereinafter referred to as rail), and whose short side is made smaller than the groove width. It has a structure that allows it to be rotated 90 degrees to reach the nut when attached to a rail, etc. (Actual M3-,?,!-95γ), or a square nand or rectangle whose width across opposite sides is larger than the width of the rail, etc. A nut is inserted and latched from one side of the rail, etc., and can be moved to a predetermined mounting position (Jikko Sho 99'-93g
'1) is known, but while the former can be attached and detached at any position on the rail, etc., there is a risk of it coming off due to the rotation of the nut, and the latter is always attached to the rail, etc. from one open end of the rail, etc. There was a problem in that it had to be inserted (therefore, it was not possible to reprint in the hole). Therefore, it cannot be used unless there is an open end on one side of the rail etc.
Even if there is an open end on one side of the rail, etc., when it is pushed onto the board, the end is usually closed so that the mounting nut cannot be removed. Therefore, if two or more nuts are required than the number calculated and fitted in advance, there is a problem in that the end of the rail, etc. must be opened and the extra nuts fitted. In addition, since the short side of the rectangular mounting nut requires the diameter of the label provided on the plate (10λ times the length, ld+a), it is natural (for strength reasons) that the groove width of the rail, etc. 1 + β (α < β).Therefore, it was necessary to make the groove width of the rail, etc. thicker (Zuro), and because there was a risk that the plate would shift (as shown by the chain line in Figure 13) when the equipment was expanded, the plate It was necessary to make the thickness so that it would not bend when tightened.

However, this invention is constructed by attaching the latching spring to a plate body having a vertical and horizontal width larger than the groove width of a rail or the like, so that the groove width can be set slightly larger than the label diameter d (for example, /
(about 2d) Therefore, the thickness of the plate should be strong enough to withstand feeding, and there is no need to consider curvature as in the past.

That is, to explain this invention with reference to an embodiment, a sign plate 3 to which a center f'i1 (screw) of a flat rectangular metal plate is to be screwed.
and cut grooves q, q, and a on the short sides of the metal plate/set, respectively.
A latching spring 2, which latches to the opposing edge of the rail S, is fitted into the notched groove 4a so as to be able to move toward and away from each other, thereby forming a mounting hole 1-A.

The retaining spring 4 is made of a single wire rod shaped like a front gate and a funnel shape on the sides, with a diamond-shaped bulge at the bottom of the side, and the width W of the bulge is equal to or slightly larger than the width of the rail.
W≧W+), this is to serve as a guide when fitting the core handle 1 to the rail (Fig. 7), and to prevent it from coming off during the fitting operation (Fig. 3). Further, the one end of the latching spring is not limited to a ray. In the drawing (Fig. 2), the - side a is bent in an M shape, and the other side 1] is bent in a 1-1 shape, but the other side is the one where both ends of the spring are bent, and the spring end If connected, both sides can be bent in an M shape. Any shape, such as a mouth shape, an arc shape, or a wavy shape, can be used as long as the shape achieves this purpose of point latching. Further, the side shape of the spring is not limited to the diamond-shaped bulge, and it goes without saying that the spring may have a circular bulge (as shown in the left figure) or may have no bulge.

Next, the operation of dropping the extra issue nut A of this invention onto the rail 5 will be explained. First, as shown in Fig. 7, place the lower end of the latch spring O on the railco, apply downward pressure as shown by the arrow 7 to lower the enlarged part O a of the latch spring O (Fig. 9), and then press down as shown by the arrow 7. If you move it in the direction of 10 and push it down in the direction of the arrow // (Fig. 76), you can drop it in as shown in Fig. 1. Once the nut has been dropped, it cannot be removed unless it slides to the end of the rail.

According to this invention, a sign plate is provided in the center of a board whose vertical and horizontal sides are larger than the groove width of a rail, etc., and a hanging suffling is fitted to this board, so that it can be dropped onto a rail, etc. at any position. Since the groove width can be made as narrow as possible, even if the plate is made relatively thin, it can be used effectively.

Furthermore, the mounting nut maintains its current position even if the rail etc. tilts after being dropped, and has the effect of always positioning the sign plate in the center of the groove.
