Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a field edge attachment fitting used when joining a field edge and a field edge receiver.

(Prior Art) As a mounting metal fitting used for joining a field edge and a field edge receiver, the one shown in FIG. 4 is known.

This metal fitting A consists of a horizontal part 1 and a falling part 2 connected to the horizontal part 1. 1a
The field edge 4 and the field edge receiver 5 are joined by bending the field edge receiver 5 along the upper end portion of the field edge receiver 5 with fingers.

However, in the case of this metal fitting A, only a plate material thick enough to be bent by hand can be used, and each piece does not have sufficient strength, so a large number of metal fittings A must be used during construction. In addition, since there are likely to be variations in the bending work of the horizontal part tip 1a at the site, the level of the field edge 4 may be out of order, and accidents may occur due to not bending the top part tip 1a sufficiently. This has resulted in the following.

For this reason, a metal fitting B as shown in FIG. 5 is also used.

This metal fitting B consists of an upper surface part 6 and side plates 7, 7 formed downwardly on the sides of the upper surface part 6, and is made by extending the tip of the upper surface part 6 forward by a predetermined length and folding it upward. A clip piece 8 for fitting one side of the field edge receiver 5 is formed protrudingly, and the side plate 7
A spring piece 9 is formed to be elastically supported on both sides of the field edge.

However, although such a metal fitting B can solve the above-mentioned disadvantages of the metal fitting A, it has the following problems. That is, the clip piece 8
Since it is formed by protruding forward from the tip and then folding back upward, this part requires 180 degree bending, which increases the number of processing steps and requires additional material. . Furthermore, in this metal fitting B, since the clip piece 8 portion protrudes forward from the upper surface portion 6 and the side plate 7, the strength of this portion is not sufficient.

(Purpose) In view of these points, the present invention is easy to manufacture,
The purpose of this is to provide a field edge mounting bracket that can ensure sufficient strength, and its feature is that by bending both ends of a substantially rectangular steel plate in the same direction, the upper surface A metal fitting main body having a substantially U-shaped cross section is formed, and an inward locking element is formed on both sides of the metal fitting main body, and the inner locking element is elastically engaged with a groove provided on both sides of a field edge made of a square steel pipe. The piece is cut and bent, and the upper surface of the metal fitting body has a fitting groove that stands vertically along the front-rear direction of the metal fitting main body, and a fitting groove into which the flange portion of the field edge receiver is fitted at the lower end. This device is characterized by a pair of clip pieces in the shape of a horizontal L-shape projecting from the left and right sides.

(Example) Hereinafter, the present invention will be described in detail based on the illustrated example.

FIG. 1 shows a mounting bracket according to an embodiment of the present invention. Reference numeral 10 in the figure is a metal fitting main body, and this metal fitting main body 10 is constructed by bending both ends of a rectangular steel plate material in the same direction.
2 and 12, and has a substantially U-shaped cross section.

A pair of left and right clip pieces 13 are provided protruding from the upper surface portion 11. This clip piece 13 is cut and raised vertically from the plate surface of the upper surface portion 11, and has a shape similar to a horizontal L-shape. The short side 13a of the clip piece 13 is connected to the top surface 11.
The long side portion 13b extends in the front-rear direction of the metal fitting main body 10 with the plate surface perpendicular. A groove portion 14 is formed between the long side portion 13b and the upper surface portion 11. This groove portion 14 has a height of 5
The thickness of the flange portion 5a is formed to be slightly smaller than that of the flange portion 5a, and the flange portion 5a is forcibly fitted into the plate.

Both side walls 12 falling from both sides of the upper surface part 11
Inward locking pieces 15 are cut into both ends of the metal fitting main body 10 in the front-rear direction. This locking piece 1
5, the upper part has spring properties in the width direction of the metal fitting body 10, and when the both sides of the metal fitting body 10 are held on both sides of the field edge 16 made of a square steel pipe, the grooves 17 on both sides of the field edge are formed. is elastically locked.

Further, the reference numeral 18 shown in FIG. 3 indicates the upper surface portion 11.
A cushioning material, such as Soflon tape, is attached to the underside of the

The mounting bracket configured in this way is
It is used as shown in the figure. That is, when the lower flange portion 5a of the field edge receiver 5 is placed against the groove portion 14 of the clip piece 13 and the rear end portion of the metal fitting body 10 is struck with an appropriate tool, the clip piece 13 is fitted into the flange portion 5a. The fitting main body 10 is integrated with the field frame receiver 5. The groove portion 14 of the clip piece 13 is
If the height of the starting end is made large and the height decreases to a predetermined value as you go to the back, it becomes easier to fit the field edge receiver 5.

Next, when the field edge 16 is pushed between both sides of the metal fitting body 10 from below, the upper ends of the locking pieces 15 on both sides of the metal fitting body elastically fit into the grooves 17 provided along the longitudinal direction on both sides of the metal fitting body. The field edge 16 is fixed to the metal fitting main body 10 by fitting into the target.

This metal fitting that integrates the field edge 16 and the field edge receiver 5 is attached so that the lower end surface of the long side portion 13b of the clip piece 13 bites into the flange portion 5a of the field edge receiver 5, so that the field edge receiver It is firmly fixed at 5. Further, even if the weight of the edge 16 is applied to the clip piece 13, the clip piece 13 has a strong resistance against bending because its plate surface is oriented in the vertical direction.

Furthermore, in the metal fitting of this embodiment, since the packing material 18 is attached to the lower surface of the upper surface part of the metal fitting body, even if the edge surface and the lower surface of the upper surface part 11 of the metal fitting body rub against each other, no metallic sound is generated. Not only
Even if there is product variation in the mounting fittings, the joining level between the field edge 16 and the field edge receiver 5 will not be disturbed. This packing material 18 does not need to be attached to the entire lower surface of the upper surface portion 11, and may be provided only to the center portion.

A stopper for preventing the edge receiving flange portion 5a from slipping may be provided on the upper surface of the metal fitting body 10 in front of the clip piece 13.

(Effects) As described above, according to the present invention, a pair of right and left clip pieces forming a substantially horizontal L-shape are formed upright on the upper surface of the metal fitting body, and are provided between the lower end and the plate surface of the upper surface. Since the flange part of the field edge receiver is fitted into the groove, there is no need for 180 degree bending, which is required for conventional clip pieces. The lower end surface of the can be reliably fixed to the field edge receiver by biting into the flange part. In addition, even if the weight of the edge held on both sides of the metal fitting body is applied to the clip piece, the clip piece can exhibit strong bending strength because its plate surface is oriented in the vertical direction. .

Furthermore, unlike other conventional mounting fittings, it does not require manual bending work, so a rigid metal plate can be used, and the strength of the mounting fitting as a whole can be increased.
