Description

[Detailed Description of the Invention] The present invention relates to a lattice body in which a plurality of lattices are rotatably connected to upper and lower beams at regular intervals, and used as a fence or fence for a balcony, stairs, etc.

The connection between the upper and lower bars and each lattice in the lattice body is generally achieved by screwing screws into the abutting portions of the upper and lower bars and each lattice. Therefore, even if a strong connection is possible,
It takes a lot of work to screw in a large number of screws to connect the lattice, and the connection between the upper and lower crosspieces and the lattice is completely fixed, making it impossible to rotate the lattice. The drawback was that adjusting the angle of the grating was extremely troublesome.

The present invention has been made in view of the above points, and in a lattice body in which a plurality of lattices are connected via connecting blocks to opposing protrusions provided on the upper and lower crosspieces, the protrusions on the upper and lower crosspieces are arranged in a predetermined direction in the length direction. The connecting block has holes for attaching the connecting block at intervals, and the connecting block has a forked leg section that connects a pair of legs. The forked legs of the connecting block are elastically formed so as to be expandable, and a shaft that engages with the hole of the protruding piece is protruded from one opposing surface of the leg forming the gap. It is rotatably locked, a notch groove is formed at the end of the lattice to receive the protruding pieces of the upper and lower crosspieces, and the other end of the connecting block is inserted into the end of the lattice, and the connecting block and the protruding pieces are connected at the end of the lattice. A configuration in which the locking hole formed on the outer surface of the other end of the connecting block and the locking protrusion formed at the corresponding position on the end of the lattice are fitted and fixed. To provide a lattice body with a simple structure, which facilitates the work of connecting the upper and lower crosspieces and the lattice, and also allows the angle of the lattice to be extremely easily adjusted when used as a staircase fence, etc. With the goal.

Hereinafter, one embodiment of the present invention will be described in detail based on the drawings.

Fig. 1 is a partially omitted front view of an embodiment in which the lattice body is used as a stair fence, Fig. 2 is an enlarged exploded view of the connecting part between the upper rail and the lattice, and Fig. 3 a and b are the connecting blocks. 4 is a sectional view taken along the line A-A in FIG. 1, and FIG. 5 is a sectional view taken along the line B-- in FIG.
6 shows a side view of the second embodiment of the connecting block. In these drawings, 10 is an upper and lower crosspiece, 20 is a lattice, and 30 is a connecting block.
The upper and lower bars 10 and the grid 20 are mainly extruded from metal such as aluminum.

The upper and lower crosspieces 10 are composed of a main body 11 having a rectangular hollow cross section, and a protrusion 12 provided in the longitudinal direction of one side of the main body 11. And upper rail 10
The projecting pieces 12 are arranged downward, and the lower crosspiece 10 is arranged with the projecting pieces 12 facing upward, with the respective projecting pieces 12 facing each other and inclined in parallel at a predetermined angle.

Further, holes 13 are bored in the protruding pieces 12 of the upper and lower crosspieces 10 at appropriate corresponding intervals.

The lattice 20 consists of a main body 21 having a hollow rectangular cross section and double projecting pieces 22 provided on both sides of the main body 21 in the longitudinal direction. The double protruding piece 22 is formed by protruding two pieces of protruding pieces in parallel with a gap having approximately the same width as the thickness of the protruding piece 12 of the upper and lower crosspieces 10. In addition, double protrusions 22 on both sides of the end of the main body 21
In between, there is a notched groove 2 having the same width as the gap between the double projecting pieces 22.
3 is provided. Further, a locking protrusion 24 formed by caulking with the main body 21 is provided on the inner side of the front and rear surfaces of the end portion of the main body 21.

The connecting block 30 is formed into a bifurcated shape from an elastic material such as synthetic resin, and its legs 31 can be expanded. A semicircular base 32 is attached to the tip of the leg 31.
Also, one of the legs 31 has a protruding piece 1 of the upper and lower crosspieces 10 on the surface facing the other leg 31.
A shaft 33 that fits into a hole 13 provided in 2 is provided protrudingly. The legs 31 of the connecting block 30 are connected to the lattice body 21.
A locking hole 34 that engages with a locking projection 24 provided on the lattice main body 21 is provided on the front and rear surfaces thereof. Note that the arc surface of the semicircular base 32 provided at the tip of the leg portion 31 has the same radius around the shaft 33, and the radius is the same as that of the hole provided in the protrusion 12 of the upper and lower crosspieces 10. From the center of 13,
The distance is made equal to the distance between the upper and lower crosspieces 10 and the opposing surface of the main body 11. Therefore, the connecting block 30 is
No matter what angle it is attached to the projecting piece 12, the arcuate surface of the base 32 comes into contact with the facing surface of the main body 11 of the upper and lower crosspieces 10, so it will not rotate unless an external force is applied.

The lattice 20 and connection block 30 of the upper and lower crosspieces 10 constructed in this manner are connected in the following manner. First, the protruding piece 12 of the upper and lower crosspieces 10 has a hole 13 provided therein.
Next, the connecting block 30 is rotatably held by opening the legs 31 and fitting the shaft 33. Subsequently, the lattice body 21 is attached to the legs 31 of the connecting block 30.
and the locking protrusions 24 of the lattice body 21 and the locking holes 34 of the connecting block 30 are engaged. In this way, the connection block 30 connects the upper and lower crosspieces 1
With the shaft 33 fitted into the hole 13 of the protruding piece 12 of No. The protruding piece 1 of the upper and lower crosspieces 10 is formed by the notch groove 23 of
2, while firmly fitting into the leg portion 31 of the connecting block 30. Thereby, the upper and lower crosspieces 10 and the lattice 20 are rotatably and firmly connected.

It should be noted that the present invention is not limited to the above-mentioned embodiments, and can also be applied to, for example, a lattice body in which the upper and lower crosspieces 10 are arranged horizontally, and the shape of the lattice 20 can also be changed to the double projecting pieces 22 on both sides. Of course, it is possible to remove the . In addition, the connecting block 30
It can also be U-shaped as shown in FIG.

As described above, according to the present invention, the shaft protruding into the gap between the forked legs of the connecting block is fitted into the holes formed at predetermined intervals in the projecting pieces of the upper and lower crosspieces, and the connecting block is rotatably mounted. Therefore, the connection angle between the upper and lower crosspieces and the lattice can be easily adjusted, and therefore, lattice bodies such as stair fences having various inclination angles can be easily constructed.

Moreover, in addition to the connection with the protrusion, it is only necessary to insert the other end of the connection block into the end of the lattice, and to fit the locking protrusion of the lattice into the locking hole of the connection block. There is no need for screwing with screws, etc., making the connection work very easy.

Furthermore, the portion of the connecting block that fits with the projecting piece is covered by the end of the lattice due to the presence of the cutout groove of the lattice, and is not exposed.
