Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lattice joining device for fences, gates, etc.

Conventionally, in the middle gate of a fence, the lattice and the horizontal beams have been joined by screws or welding. However, there is a problem in that work efficiency is poor (it takes a lot of man-hours to join a large number of grids on-site using screws or welding). Further, in the case of welding, there is a problem of poor reliability when performed by an amateur.

For this reason, fences and the like are assembled in advance at a factory and installed at the site, but there are problems in that the transportation volume becomes large and it is inconvenient to handle. It was,
When joined by screwing or welding, there is a risk of rust appearing from the joint.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a lattice joining device that can be easily joined, requires less man-hours, and can prevent rust from forming in the joined portions.

In Figures 1 through 4 which show an embodiment of the present invention, 1 is a fence lattice, 2 is an upper horizontal bar serving as a cap, and 3 is a lower horizontal bar serving as a lower chord member. The upper horizontal beam 2 is formed into a rectangular pipe shape with a narrowed lower half, and a pair of elastic locking pieces 4 are provided on the inner surfaces of both sides to face each other. The elastic locking piece 4 is provided over the entire length of the upper horizontal beam 2 and is inclined diagonally upward. The upper horizontal beam 2 is formed by extrusion using an aluminum pedestal or plastic nuts, or by composite extrusion of metal and glass. In the case of composite extrusion, a dual structure is formed in which the inner surface is made of defustic and the outer surface is made of metal, and the elastic locking piece 4 is formed from the defustic part. On the other hand, the inner surface may be made of metal. The lower surface of the upper horizontal crosspiece 2 is provided with square-shaped grid insertion holes S at a constant pitch, and both elastic locking holes S are provided above the grid insertion holes 5. A grid fitting notch 6 is provided at the tip of the piece 4. The lattice l is made from a square pipe, and its upper end is fitted into the lattice insertion hole 5 of the upper horizontal beam 2. The lattice 1 has locks @7 on both sides of the upper end, and the tips of the upper horizontal beam 20, elastic locking piece 40, and notch IM6 are engaged with the locking grooves γ. Additionally, the lattice 1 has slits 8 on the front and rear surfaces of the upper end. The lower horizontal bar 3 is provided above and below the upper horizontal bar 2, and has the same structure as the twill structure of the upper horizontal bar 2 and the lattice 1, and is connected to the lower end of each lattice 16.

Because of this configuration, by simply inserting the lattice 1 into the lattice fitting hole 5Klf of the horizontal bar 2°3, the elastic locking piece 4 engages with the locking groove 7, and the lattice 1 and the horizontal bar 2 .3 can be joined. Therefore, joining work 1. It is easier and faster to perform the work, compared to conventional screwing or welding.
The number of man-hours required will also be reduced.

Since the elastic locking piece 4 has a slope opposite to the pulling direction,
It is easy to push the lattice 1 in, and it is difficult to remove the lattice 1 after pushing it in. Also, since the ends of the lattice 1 are provided with the ribs 8, elasticity can be obtained at the ends of the lattice 1. Insertion of the grid element 1 between the elastic locking pieces 4 becomes even easier. Furthermore, since the lattice 1 fits into the lattice fitting hole 5 of the horizontal bar 2.30 and also fits into the lattice fitting notch 6 of the elastic locking piece 4, the lattice 1 is fitted horizontally. Pier! , 3, and the lattice shape becomes a parallelogram Kf shape. Therefore, it is difficult for the engagement between the first elastic locking piece 4 and the locking groove 7 to be easily disengaged, and since the connection can be performed by the nine elastic retaining pieces 4 provided inside the horizontal crosspiece 2.3, Unlike those that are joined by screws or welding, there is no need to apply paint or the like after joining, and there is no problem of rust forming on the joints and making them unsightly.

FIG. S shows another embodiment. That is, the horizontal bar 2' is composed of a downward lip channel member 2s and an upward channel member 2b, and the upper part of the upward channel member 2b is inclined inward to form an elastic locking piece 4'. The channel member 2 and the upward channel member 2b are made of iron, and the elastic locking piece 4' has high elasticity. The lattice 1' is provided with slits 8 as shown in FIG. 3, but the rest is the same as in the first embodiment. Also in this configuration, bonding can be easily performed in the same manner as described above.

As described above, in the lattice joint stirrup of the present invention, the ends of the lattice are inserted into the lattice insertion holes provided in the horizontal beam, and the pair of elastic locking pieces on the inner surface of the horizontal beam are Since the K is designed to engage with the locking groove of the lattice, the horizontal bars and the lattice can be joined simply by inserting the lattice, and therefore the number of man-hours is reduced and the joining work can be carried out easily and quickly. Moreover, since the joint is made using elastic locking pieces inside the horizontal crosspiece, there is no problem of the joint becoming unsightly due to rust, unlike conventional joints using screws or welding.

There is an effect.
