DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metal fitting for a snow melter for rails.

[0002]

2. Description of the Related Art As a device for assembling a rail snowmelter for heating a rail by contacting the side surface of the rail, there is, for example, a structure disclosed in Japanese Utility Model Publication No. 4-23921.

In this conventional example, a horizontal axis is assembled to the other end of a holding plate metal fitting that hooks one end to the bottom by overlapping the lower surface of the bottom of the rail with a horizontal plate portion. A press-shaped metal fitting is rotatably supported, and the metal fitting is always tilted to the rail side by a pressing spring wound around the horizontal axis, and a snowmelter is held on a vertical plate portion of the metal fitting. It has a structured structure.

[0004]

The conventional example described above cannot be applied to rails having different bottom widths because the width (in the direction of the bottom width of the rail) of the holding flat metal member is constant.

The present invention has been made by focusing on such a drawback of the conventional example.

[0006]

SUMMARY OF THE INVENTION A main frame provided with a U-shaped bent portion at one end of a mounting piece for engaging one side end of a bottom portion of a rail, and another other side end of the bottom portion of the rail. A holding frame provided with an engaging piece at one end of an assembling piece, a tension spring being stretched between the assembling pieces and slidably fitted to each other to heat a side surface of the rail. A structure in which a holding portion is connected to the bent portion of the main frame, and a base portion of a pressing rod for pressing the free end side from the one side end side of the rail with a finger is fixed to the mounting piece of the holding frame. That is.

[0007]

The pressing rod is pressed against a tension spring so that the bent portion provided at one end of the mounting piece on the main frame side is engaged with one side end of the bottom of the rail, and the pressing rod is pressed against the main frame. Then, the holding frame is moved in the separating direction, and the locking piece provided on the mounting piece on the holding frame side is locked to the other side end of the rail bottom. The bent portion on the side engages one side end of the rail bottom, the locking piece on the holding frame side locks on the other side end of the rail bottom, and is attached to the rail of the snow melting device held by the holding portion. A condition is obtained, which is maintained by the tension spring.

1 is a sectional view, FIG. 2 is a perspective view of a main frame, and FIG. 3 is a perspective view of a holding frame according to the present invention.

A mounting bracket A for a snow melting apparatus for rails according to the present invention is constructed by assembling a main frame 1 and a holding frame 2 with each other.

[0010] The main frame 1 is composed of mounting pieces 3 arranged in a horizontal direction.
Is bent into a U-shape to engage one side end 4a 'of the bottom 4a of the rail 4, and a free end of an upper piece 5a of the bent portion 5 is bent to form a vertical direction. The U-shaped frame piece 6b is superimposed on the piece 6a continuously provided in the above-described manner to form the holding portion 6 of the snow melting device 7.

The part 6a elastically deforms and serves to press the snow melting device 7 assembled to the frame part 6b against the side surface of the rail.

The assembling piece 3 of the main frame 1 includes an engaging portion 3a having a V-shaped cross section at the other end corresponding to the one end, and an assembling piece is provided at the bottom of the engaging portion 3a. 3 is provided with a long hole 8 extending in the longitudinal direction, and a receiving portion piece 9 is protruded by cutting and raising a portion immediately below the bent upper portion piece 5a on the extension of the long hole 8 upward.

The holding frame 2, like the main frame 1, is bent upward at one end of an assembly piece 13 disposed in the horizontal direction to engage with the other one side end 4 a ″ of the bottom 4 a of the rail 4. The holding piece 15 for stopping the holding frame 2 is provided.
3 is provided with an engaging portion 13a having another end corresponding to the one end bent at a V-shaped cross section, and a portion of the bottom of the engaging portion 13a near the other end and a portion on the locking piece 15 side. Each of the engagement pieces 10 and the reception pieces 19 are cut and raised upward.
(Facing the receiving piece 9), and the base of the pressing rod 18 is fixed to the outer surface of the mounting piece 13, and the free end 18 ′ thereof is bent in the main frame 1. It extends in the direction of the part 5.

The main frame 1 and the holding frame 2 are provided with an engaging piece 10.
To the main body frame 1 and the assembling piece 3
The engaging portion 3a of the mounting piece 13 on the side of the holding frame 2
a, and the end of the tension spring 11 is engaged with the receiving piece 9, 19 formed on each of the frames 1, 2, and the tension spring 11 is attached to the mounting pieces 3, 13. And bent together with the bent piece 5 and the locking piece 1 via the rail bottom 4a.
5 are always urged in the direction in which they are close to each other.
It constitutes.

The snowmelt 7 is attached to the holding portion 6 by utilizing the elastic deformation of the upper and lower pieces 6b ', 6b' of the frame piece 6b of the holding portion 6, and the bent portion on the main frame 1 side. 5 so that one bottom side end 4a 'of the rail 4 is relatively engaged with the rail 4, the bent portion 5 is hooked on the side end 4a', and the bent portion 1 on the holding frame 2 side.
The holding frame 2 is pressed by the pressing rod 18 against the bias of the tension spring 11 so that the rail 5 is disposed at a position facing the other bottom side end 4a '' of the rail 4 and the main frame. When the finger is moved in the direction in which the locking piece 15 is moved away from the base 1 and the hand is released, the locking piece 15 is biased by the tension spring 11 so that the bottom side end 4 a ″ is formed.
The bent portion 5 is engaged with the bottom end 4a ', and the snow melting device 7 is attached to the rail 4.

Further, by pressing the pressing rod 18 to move the holding frame 2 against the bias of the tension spring 11, the mounting bracket A is removed from the rail 4.

Note that the main frame 1 and the holding frame 2 are
By sliding-fitting each other at a and 13a, the movement in the approaching direction or the separating direction is performed smoothly, and the biasing direction of the tension spring 11 can be made constant.

Further, since the engaging piece 10 is engaged with the elongated hole 8, the main frame 1 and the holding frame 2 are not separated more than necessary.

The bent portion 5 and the locking piece 15 of the embodiment are elastically deformed by stainless steel as a material.
The bent portions 5 need not be pressed against the bottom end 4a '. However, it is possible to assemble the rail 4 more firmly by pressing (elastic deformation).

The number of mounting brackets A is appropriately determined according to the size (length) of the snow melting device 7.

The locking piece 15 has such a height that it does not protrude above the bottom 4a of the rail, so that the so-called tong rail overlaps above the bottom 4a and comes into contact without any trouble. Hardware can be used.

[0022]

The present invention has the configuration described above,
Rails with different bottom widths can also be used.

Also, since the bottom end side is relatively engaged with the U-shaped bent portion, the bottom end side is assembled to the rail, so that it does not come off due to vibration, and therefore, the snow melting device can be stably mounted. Get the status.

By manipulating the pressing rod, the workability of attaching to and detaching from the rail can be improved.
