FIGS. 6 and 7 show a state in which a surface lattice book (3) is mounted using a conventional mounting bracket (8). Mounting bracket
(8) is constituted by a receiving bracket (81) and a plate-like holding member (82), and a receiving piece (83) of the receiving bracket (81) applied to the outer surface of the supporting rod (31), and a supporting rod (31). By tightening the presser fitting (82) inserted in the bracket with screws (86), the thickness of the support rod (31) is pressed, and the leg (84) is bent to the receiving piece (83) and continues. The flange (11) of the window frame (1) is sandwiched by a clip piece (85) provided at the tip.

In the mounting bracket (8), the flange (11) is forcibly fitted into the holding piece (85) of the receiving metal fitting (81), and the surface lattice body (3) is moved only by the elastic return force of the holding piece (85). Because we support,
When the surface lattice body (3) is pulled downward, the sandwiching piece (85) slides on the flange (11) and the entire surface lattice (2) slips down, so that the reliability as the surface lattice is low. Furthermore, mounting bracket (8)
Before the support rod (31) of the screen lattice body (3) is squeezed and supported, the receiving bracket (81) is attached to the flange (11) of the window frame (1). In order to match the position of the bracket (81) with the support rod (31) of the screen lattice body (3),
1) has to be moved slightly on the flange (11), and at this time, there is a problem that the flange (11) is damaged.

[0005] The present invention is to clarify a surface lattice in which the mounting bracket is devised in order to solve the above problem.

[0010]

FIG. 1 shows a flange (11) of a window frame (1).
2 shows a state where the surface grating (2) of the present invention is attached.
(FIG. 1 is common to the conventional example). The area grid (2) is the area grid body
(3) and four mounting brackets (4).
The surface lattice body (3) is formed by fixing the lattice rods (35) (35) on two parallel support rods (31) (31) at a dense pitch orthogonal to the support rods (31). ing.

Each of the support rod (31) and the lattice rod (35) is a hollow body having a rectangular cross section formed of aluminum and has a lattice rod mounting wall (33) for the support rod (31) as shown in FIG. Wall opposite
(32) has a slit (34) at the center in the width direction over the entire length.
Has been established. Each support rod (31) of the surface lattice body (3)
The mounting bracket is characterized in that both ends of the frame and the window frame (1) are features of the present invention.
Connected by (4).

The mounting bracket (4) includes a receiving bracket (5) and a holding bracket (6) formed by bending a metal plate such as a stainless steel plate.
It is constituted by and. As shown in FIGS. 2, 3, and 4,
The receiving bracket (5) is a wall (32) on the slit (34) side of the support rod (31).
Plate-shaped receiving piece (51) that is long in the direction of the support rod (31)
And a leg (53) bent substantially at a right angle from the outer end of the receiving piece (51) and continuous, and a flange (11) of the window frame (1) provided at the tip of the leg (53) from the inside. It has a hooking piece (54) to be hooked. The tip of the leg piece (53) is bent in a U-shape, and the flange (11) of the window frame (1) can be fitted into the outward opening (56) of the bent portion (55) in a state where there is room. The tip of the bent part (55) is a hook
(54).

The holding member (6) is inserted into the supporting rod (31), and a pressing piece (61) which hits the inner surface of the wall (32) of the supporting rod (31) on the slit (34) side, and the pressing piece (61). 61) From the outer end of the receiving bracket
The leg (53) is bent at a substantially right angle along the leg (53), and is composed of a projecting piece (63) slightly longer than the leg (53). A bent piece that fits into the U-shaped opening (56) of (5)
(64).

As shown in FIG. 5, a holding member (6) is provided with a holding piece.
Two bulging ribs (60) continuing from (61) to the strut (63)
(60) is press-formed to increase strength. A plurality of screw holes (62) corresponding to the through holes (52) (52) of the receiving piece (51) of the receiving metal fitting (5) are provided between the holding pieces (61) between the ribs (60) and (60).
(62) has been established.

However, to attach the screen grid (2) to the window frame (1), insert the holding piece (61) of the holding member (6) from the open end of the support rod (31) of the screen grid body (3). Then, the receiving piece (51) of the receiving metal fitting (5) is applied to the wall (32) of the support rod (31) from outside, and the receiving piece (5
1) and the holding piece (61) are connected with the screw (7). At this time, both pieces (51) (6
The screw (7) is lightly tightened so that the support rod (31) can slide between 1).

Next, the entire receiving bracket (5) is slid outward so that the flange (11) of the window frame (1) fits into the U-shaped opening (56) of the receiving bracket (5). Flange (11) in shape opening (56)
Fit. When the screw (7) is tightened in this state,
(51) and the holding piece (61) clamp the thickness of the support rod (31), and the projecting piece (63) hits the flange (11) of the window frame (1) to receive the flange (11). The surface lattice main body (3) can be fixed to the window frame (1) by being pressed between the hooking piece (54) and the tip of the projecting piece (63). The remaining three sets of mounting brackets (4) are also tightened with screws (7).

As described above, the mounting bracket (4) allows the flange (11) of the window frame (1) to be fixed to the hooking piece (54) and the tip of the projecting piece (63) by the tightening force of the screw (7). , It can be firmly fixed to the flange (11), and the entire surface lattice (2) does not slip down even if the surface lattice body (3) is pulled downward.
Also, by tightening the screw (7), the receiving piece (51) and the holding piece (6
The thickness of the supporting rod (31) by the thickness of the support rod (31) and the pressure of the flange (11) of the window frame (1) by the hooking piece (54) and the projecting piece (63) can be simultaneously performed. Good workability.

The flange (1) of the window frame (1) is loosened by the screw (7), that is, the hooking piece (54) and the projecting piece (63).
Attach the mounting bracket (4) to the flange (11) without clamping
By moving it upward, the positioning of the plane lattice body (3) and the support rod (31) can be performed, and this operation does not damage the flange (11).

[0019] As in the embodiment, the projecting piece (63) of the presser fitting (6).
If a bent piece (64) is provided at the tip of the (1) so that the bent piece (64) comes into contact with the flange (11), it is more effective to prevent the flange (11) from being damaged. The present invention is not limited to the configuration of the above embodiment, and various modifications can be made within the scope described in the claims.
