Description

[Detailed Description of the Invention] The present invention relates to an improvement of a connecting fitting used to connect a post and a rim in a wire mesh fence.

Generally, when installing a wire mesh fence, the upper and lower ends of the diamond-shaped wire mesh are attached to the upper and lower edges of the posts via connecting fittings, and the locking rods are attached to the side edges of the wire mesh. The upper and lower ends of the locking rod are supported by the upper and lower connecting fittings, but in order to increase the support strength of the wire mesh, it is desirable that the locking rod is fixedly supported by the connecting fittings. In this way, there is a method of fixedly supporting the locking rod by screwing it to the connecting metal fitting, but this not only complicates the structure of the connecting metal fitting, but also makes it difficult to connect the rod and the rim using the connecting metal fitting. This method has the drawback that the work of assembling the fence becomes extremely troublesome because the work of screwing the locking rods must be done separately.

In view of the above, the present invention aims to provide a connecting fitting that can easily and securely support a locking rod without screwing it. A pair of tongue pieces for holding a plate-shaped locking rod are provided protrudingly on the groove edge, and a projection is provided on the tongue piece to fit into a locking hole provided in the locking rod. This is a characteristic feature.

Hereinafter, embodiments of the present invention will be described in detail based on the drawings.
2 and 3 are struts erected on the ground at regular intervals, and rims 2 and 3 are installed above and below the pillars 1 via connecting fittings 4 and 5, and wire mesh is attached to the lower or upper surface of the rims 2 and 3. Insertion grooves 6 and 7 are provided, and the upper and lower ends of the diamond-shaped wire mesh 8 are inserted and locked into the insertion grooves 6 and 7.

As can be seen from FIGS. 3 and 4, the connecting fittings 4 and 5 are provided with split tube-shaped support connecting portions 9 and 10 and body edge connecting portions 11 and 12, and these connecting portions each have a By fitting the strut 1 and the rims 2, 3 and attaching bolts 13, 14 at positions away from the rims 2, 3 in the rim connecting parts 11, 12, the strut 1 and the rims 2, 3 are attached. The upper connecting fitting 4 is formed into a half-shape by providing the dividing groove 15 only in the lower half, while the lower connecting fitting 5 has the dividing groove 16 in the upper half. By providing it on the lower surface, it is divided into two metal fitting pieces 5a, 5a.

Therefore, the connecting fittings 4 and 5 have their grooves 1.
A pair of tongue pieces 17, 17 and 18, 18 are provided protruding from the groove edges of the grooves 5, 16, and are opposed to each other with a certain clamping interval. , 19 and 20, 20, and on the other hand, a flat locking rod 21 oriented parallel to the surface of the wire mesh is inserted and engaged with the row line at the side end of the wire mesh 8. Insert the upper and lower ends into the grooves 15, 16 of the connecting fittings 4, 5 and attach the tongue pieces 17, 17.
and 18, 18, and the protrusions 19, 19 and 20, 20 at the tips of the tongues are fitted into locking holes 22, 23 provided in the locking rod 21 and locked therein.

When actually installing the locking rod 21, the upper connecting fitting 4 is elastically pushed open slightly and the tongue pieces 17, 1 are attached.
When the upper end of the locking rod 21 is inserted between the gaps 7 and 7 and the connecting fittings are released, the elastic restoring force causes the tongue pieces 17, 17 to
The protrusions 19, 19 are inserted into the locking hole 22 while the two metal pieces 5a, 5a are held between the tongue piece 1 and the lower connecting metal fitting 5.
The locking rod 21 is held between 8 and 18, and the protrusions 20 and 2
0 is fitted into the locking rod 23, and in that state, both metal fitting pieces 5a, 5a are tightened with the bolt 14.

According to the connecting fitting of the present invention having the above configuration,
A pair of tongue pieces are provided oppositely on the groove edges of the split groove, a projection is provided at the tip of the tongue piece, and a locking rod that is engaged with the end of the wire mesh is sandwiched between the tongue pieces. Since the protrusion is fitted and locked into the locking hole of the locking rod, the pair of tongues can reliably prevent the locking rod from shaking in the width direction of the split groove, and at the same time, the projection can be Therefore, it is possible to prevent the locking rod from moving away from or toward the support, and thereby the locking rod can be connected in a state where rattling and displacement of the locking rod are simultaneously prevented. Can be securely fixed to metal fittings.

In particular, the split grooves in the above-mentioned connecting fittings are formed to have a width larger than the thickness of the wire mesh in order to allow the wire mesh to be inserted therethrough, so when a plate-shaped locking rod is inserted into the split grooves, it inevitably becomes loose. Easy to cause irritation. For this reason, in the past, the troublesome fixing method of screwing the locking rod to the connecting fitting has been adopted, but this inevitably increases the number of man-hours and takes time to install the wire mesh fence.

In the present invention, by simply adopting a simple structure of providing a pair of tongue pieces with protrusions, the connecting fitting can be attached to the support at the same time as the connecting fitting is attached to the support without using the troublesome fixing steps as in the past. It is also possible to install the stopper in a fixed manner.
In the installation work of a wire mesh fence in which a large number of locking rods are provided, by simplifying the fixing of the locking rods in this way, it is possible to realize a significant reduction in the overall work man-hours and working time.
