2. Description of the Related Art In a conventional gate, a frame 1 and a grid member 2 are connected as shown in FIG. A concave groove 3 having the same width as the width W of the square pipe-shaped lattice material 2 is provided in the longitudinal direction on the inner peripheral side of the frame 1, and the end portion of the lattice material 2 is fitted into the concave groove 3. A screw tool 7 is screwed and fastened from the frame 1 side to the end of the lattice member 2. In this case, the end portion of the grid material 2 has the groove 3
The grid member 2 is attached so that it does not rotate by fitting into.

[0003]

The frame 1 and the grid member 2 are formed by extruding a metal such as aluminum, but the end of the grid member 2 is formed by the frame 1.
The grid member 2 has a structure that fits in the groove 3 of
If the width of the frame 1 is different, the frame 1 must be prepared accordingly, and there is a problem that various types of frame 1 having different widths of the groove 3 must be prepared.

The present invention has been made in view of the above problems, and an object of the present invention is to connect grid members having different widths even with one type of frame, and the grid members can rotate. It is to provide a connection structure between a frame of a gate and a lattice member that can be fixed so that it is not fixed.

[0005]

In order to achieve the above object, the connection structure between the frame and the lattice material of the gate of the present invention is such that the frame 1 is mounted along the inner periphery of the door frame 4 framed in a rectangular shape, In a gate in which a grid member 2 is installed between parallel frame members 1 facing each other, an end face of a pipe-shaped grid member 2 is brought into contact with a surface on the inner peripheral side of the frame 1 to cut and raise from the frame 1 to the grid member 2 side. The raised piece 5 is locked to the inner surface of the end portion of the lattice member 2, the screw tool 7 is inserted through the mounting hole 6 provided in the frame 1, and the lattice member 2
It is characterized in that a screw tool 7 is screwed into a tapping hole 8 provided in the longitudinal direction.

[0006]

According to the above construction, the end face of the pipe-shaped lattice member 2 is brought into contact with the inner peripheral side face of the frame 1, and the cut-and-raised pieces 5 cut and raised from the frame 1 to the lattice member 2 side are attached to the lattice member 2. It is cut and raised by being locked to the inner surface of the end, inserting the screw tool 7 from the mounting hole 6 provided in the frame 1, and screwing the screw tool 7 into the tapping hole 8 provided in the longitudinal direction of the lattice material 2. The lattice member 2 can be attached by locking the piece 5 and the screw tool 7 so as not to rotate. Further, since positioning is performed by the cut-and-raised pieces 5 instead of positioning by the concave groove as in the conventional case, the grating material 2 can be attached even if the width is different, and it is not necessary to prepare many kinds of the frame 1.

[0007]

EXAMPLE A gate A is formed as shown in FIG. 4, and a frame 1 is attached along the inner circumference of a door frame 4 framed in a rectangular shape on the outer periphery, and between the left and right frame 1 It is formed by laying a plurality of grid members 2. The door frame 4 is a left and right vertical frame 4a
And the upper and lower horizontal frames 4b are framed in a rectangular shape. The frame 1 attached along the inner circumference of the door frame 4 is also formed of a vertical frame member 1a and a horizontal frame member 1b.

The vertical frame member 1a and the horizontal frame member 1b are shown in FIGS.
It is formed by extrusion-molding a metal such as aluminum as shown in (4), and is formed in a substantially cylindrical shape having a hollow inside. A pair of fitting pieces 9 are provided on the outer surface side of the vertical frame material 1a and the horizontal frame material 1b, and the fitting pieces 9 are fitted and attached to the inner circumference of the door frame 1. A slit 10 is provided in the vertical direction between a pair of fitting pieces 9 of the vertical frame member 1a or the horizontal frame member 1b, and on both sides in the width direction on the inner surface side of the vertical frame member 1a or the horizontal frame member 1b. The projecting edge 11 is projectingly provided in the longitudinal direction. Vertical frame material 1a and horizontal frame material 1
A butt portion 12 cut at an angle of about 45 ° is provided at an end portion in the longitudinal direction of b, and the vertical frame member 1a and the horizontal frame member 1 are provided.
The ends of b are connected by the butting of the butting portion 12. A pair of cut-and-raised pieces 5 and one mounting hole 6 are provided at the connection portion of the vertical frame member 1a with the grid member 2 on the inner surface side. The cut-and-raised piece 5 is provided at a position along the inner surface of the lattice material 2, and the cut-and-raised piece 5 is provided so as to project to the inner surface side.

The lattice member 2 is formed into a square pipe shape by extrusion-molding a metal such as aluminum, and has a tapping hole 8 provided inside over the entire length in the longitudinal direction. The end face of this lattice member 2 is a vertical frame member 1a.
Of the grid member 2 is engaged with the inner surface of the lattice member 2 and the mounting hole 6 and the tapping hole 8 are made to correspond to each other. Screw tool 7 is inserted and screw tool 7
Is screwed into the tapping hole 8 and tightened. The positional relationship between the tapping hole 8 and the cut and raised piece 5 is shown in FIG.
Various types such as (a), (b) and (c) can be considered. At this time, even if the width of the lattice member 2 changes and the width of the lattice member 2 changes, the cut-and-raised piece 5 is locked to the inner surface of the end of the lattice member 2 to prevent the lattice member 2 from rotating. The lattice material 2 can be connected by the vertical frame material 1a. At this time, the position at which the cut-and-raised pieces 5 are provided may be changed according to the width of the lattice member 2.

[0010]

As described above, according to the present invention, the end face of the pipe-shaped lattice material is brought into contact with the inner peripheral surface of the frame, and the cut-and-raised piece cut and raised from the frame to the lattice material side is attached to the end of the lattice material. Since it is locked to the inner surface, the screw tool is inserted from the mounting hole provided in the frame, and the screw tool is screwed into the tapping hole provided in the longitudinal direction of the lattice material, so that the cut-and-raised piece can be locked and the screw tool can be used. The grid material can be attached so that it does not rotate.Besides, it is possible to install it even if the width of the grid material is different because it is positioned by the cut-and-raised piece instead of positioning with the concave groove as in the past. There is no need to prepare many kinds of picture frames.
