Description

[Detailed description of the invention] This invention allows an arbitrary number of articles having engaging parts on the lower surface to be placed on a long rail with a substantially square cross section by engaging the engaging parts with both side edges of the rail. After that, the rail mounting end plates are fixedly arranged on both sides of the article so as to prevent the article from moving in the longitudinal direction of the rail.

Conventionally, as shown in FIGS. 1 and 2, this type of end plate has a pair of hook portions 4, 5, 6, and 7 and a screw hole 8 on the top surface is known, in which the hook portions 4, 5, 6, 7 are connected to both side edges 10, 11 of a long rail 9 with a substantially rectangular cross section. By screwing the screw 12 into the screw hole 8 after engaging with the screw 12,
The end plate is fixed to the rail by clamping the rail 9 between the tip and the hook parts 4, 5, 6, and 7.

However, with the conventional end plate described above, the bottom surface of the rail 9 is damaged by the tips of the screws 12, and the metal plate 1 tends to rotate around the screws 12, so there is a problem that sufficient fixing strength cannot be obtained. Ta.

Therefore, an object of this invention is to provide an end plate for mounting a rail that can obtain sufficient fixing strength without damaging the bottom surface of the rail.

In other words, the present invention provides a base having hook parts that can engage with both side edges of a long rail having a substantially square cross section, and a base that is disposed between the base and the rail and has both ends facing the flat surface of the rail. The mounted pressing piece, a fixing screw whose small diameter part is positioned in the through hole on the top surface of the base, and whose tip end is screwed into the screw hole of the pressing piece, and the fixing screw is fitted into the small diameter part of the fixing screw. The stopper member is fixed to the rail by engaging the hook portion of the base with the side edge of the rail, loosening the fixing screw, and pressing both ends of the pressing piece against the flat surface of the rail. It features an end plate for mounting rails.

This invention will be explained below based on an illustrated embodiment.

FIG. 3 is an exploded perspective view showing the rail mounting end plate A and the rail 20, which is an embodiment of this invention, and FIG. 4 shows the end plate A and the rail 20.
2 is a sectional view showing a state in which the end plate A is fixed to a metal base 21 and a metal pressing piece 22.
, a fixing screw 23 and an E-ring 34.

A pair of hook parts 25 and 26 are formed in the base 21 so as to face each other below both side edges 24, and a through hole 27 is formed in the upper surface. In addition, contact portions 28 are formed at both ends of the pressing piece 22 by bending it downward.
Rib portions 29 are also bent downward at both ends, and screw holes 30 are formed on the top surface.

The fixing screw 23 has a small diameter portion 36 formed at the base end of the threaded portion 35, the diameter of which is smaller than the diameter of the valley of the threaded portion 35, and the E ring 34 is attached to this small diameter portion 36.
The outer diameter is larger than the through hole 27 of the base 21. And base 2
1. The pressing piece 22 and the fixing screw 23 pass the fixing screw 23 through the through hole 27 of the base 21, fit the E-ring 34 into the small diameter part 36 of the fixing screw 23, and then remove the fixing screw 23. They are integrated by screwing the threaded portion 35 of 23 into the threaded hole 30 of the pressing piece 22.

Next, the operation of fixing the end plate A to the long rail 31 having a roughly round cross section will be explained. First, attach the hook portion 25 of the base 21 to the side edge 3 of the rail 31.
2, and then attach the hook portion 26 to the rail 3.
After the base 21 is engaged with the rail 31 by engaging the other side edge 32 of the pressing piece 22, the fixing screw 23 is rotated counterclockwise, that is, in the loosening direction. The portion 28 moves in the rail direction and comes into contact with the flat surface 33 of the rail 31.
Then, by further rotating the fixing screw 23, the tips of each contact portion 28 of the pressing piece 22 come into pressure contact with the flat surface 33 of the rail 31,
The end plate A is firmly fixed to the rail 31.

Note that in the above embodiment, the pressing piece 22 is provided with the contact portion 28 and the rib portion 29;
A flat metal plate may be used as the pressing piece 22. Further, in the above-described embodiment, the E-ring 34 is used as a stopper member, but as long as it has the function of preventing upward movement of the fixing screw 23, it may be achieved by other similar means. do not have.

As described above, according to this invention, the rail is clamped between both ends of the pressing piece and the hook part of the base by operating the fixing screw, so the fixing screw does not damage the bottom of the rail and can be used in a sufficient amount. It is possible to obtain fixing strength, and since the pressing piece can be stored in the internal space of the base, it has the effect that it does not need to be larger than the conventional one.
