Description

[Detailed Description of the Invention] (Field of Industrial Use) The surface lattice according to the present invention is installed on the outdoor surface of a window provided in a kitchen, a bathroom or the like for the purpose of crime prevention or the like.

(Prior Art) It is widely practiced to provide a screen lattice 1 as shown in FIG. 13 on a window that is not provided with a shutter, such as a window in a kitchen or a bathroom, for the purpose of crime prevention. When the surface grating 1 as described above is installed outside the window as described above, conventionally, the structure is as shown in FIG. 14 or FIG.

First, in the case of the structure of the first example shown in FIG. 14, the mounting leg 2 provided at the corner of the surface lattice 1 is fixed to the wall surface surrounding the window with the screw 3. Further, in the structure of the second example shown in FIG. 15, the protrusion 5 formed on the upper frame 4 forming the window and the bracket 6 provided on the upper portion of the surface lattice 1 are screwed together, and the lower frame 7 is fixed. The fixed bracket 8 and the bracket 9 provided below the surface lattice 1 are screwed together.

(Problems to be solved by the invention) However, in the case of the conventional surface lattice fixed to the outside of the window as described above, the following inconveniences occur.

First, in the case of the structure of the first example shown in FIG. 14, it is necessary to fix the base end portion (the lower end portion in FIG. 14) of the mounting leg 2 to the wall surface with the screw 3, so that this base end portion is attached to the surface lattice 1 It is necessary to project outward in the width direction (or in the vertical direction). Therefore, when the surface lattice 1 is viewed from the outdoor side, the bases of the mounting legs 2 are conspicuous and the appearance is bad.

Further, in the case of the structure of the second example shown in FIG. 15, the protrusion 5 is formed over the entire length of the upper frame 4 which is an extruded material. However, only a part of the ridges 5 is necessary for attaching the surface lattice 1, and much material is wasted.

The area grating of the present invention eliminates any of the inconveniences described above.

(Means for Solving the Problems) A surface lattice of the present invention is a surface lattice main body in which an inner side of an outer frame having a shape and size substantially the same as a window frame of a window to which the surface lattice is attached is finely divided by a plurality of crosspieces. An auxiliary frame that is formed to have substantially the same size as the surface lattice main body and is joined to the back side of the outer frame, and both ends thereof on the back surface of the auxiliary frame and the front surface of the window frame, respectively. It is provided with a plurality of connecting arms that are connected and fixed perpendicularly to each surface and connect the front surface of the window frame and the back surface of the auxiliary frame.

(Operation) When assembling the area lattice of the present invention configured as described above, the auxiliary frame is connected to the front surface of the window frame by the plurality of connecting arms, and the area grating body is connected to the front surface of the auxiliary frame. . Since the auxiliary frame, which is a simple rectangular frame and is not partitioned by crosspieces, is lighter than the main body of the surface lattice, the work of connecting the auxiliary frame to a predetermined portion on the front surface of the window frame can be easily performed. Then, by connecting the surface lattice main body to the auxiliary frame, the surface lattice main body can be connected to a predetermined portion on the front surface of the window frame. Therefore, it is possible to easily perform the work of connecting the heavy surface lattice main body to a predetermined portion on the front surface of the window frame.

In the assembled state, the auxiliary frame is hidden inside the outer frame of the plane lattice standard. Further, the plurality of connecting arms are connected vertically to the back surface of the auxiliary frame and are hidden by the auxiliary frame and the outer frame. Therefore, when the surface lattice is viewed from the outside, the auxiliary frame and the connecting arm are hidden by the outer frame and cannot be seen, and the appearance of the surface lattice is not deteriorated.

(Embodiment) FIGS. 1 to 12 show an embodiment of the surface grating of the present invention. The surface lattice main body 10 is configured by dividing the inside of the rectangular outer frame 14 into fine pieces by the crosspieces 15, 15. Outer frame 14 of these
Consists of an upper frame 11, a lower frame 12 and left and right rigid frames 13 each having an arcuate cross section.

The auxiliary frame 16 is formed in a rectangular shape having substantially the same size as the outer frame 14. The auxiliary frame 16 is formed by connecting end portions of an upper frame 17, a lower frame 18, and left and right rigid frames 19, 19 each having an L-shaped cross section with corner brackets 20, 20. As shown in FIGS. 3 to 4, a corner bracket 20 for connecting the ends of each of the frames 17, 18, and 19 which constitutes the auxiliary frame 16 is L
At the inner edge of the V-shaped body 21, folding walls are formed at right angles to each other.
22 and 22 are formed, and the cross section is also L-shaped.

In the corner bracket 20 formed in this way, four small circular holes 33, 33 are provided at the corners of the main body 21, and two connecting portions 23, 23 separated from the corners of the main body 21 are folded. Two screw holes 24 and 25 are formed in the walls 22 and 22, respectively. When such a corner bracket 20 is used to connect the frames 17, 18, and 19 to each other to form a rectangular auxiliary frame 16, the circular holes formed at the ends of the frames 17, 18, and 19 are used. Screw 26 inserted,
26 is screwed into the screw holes 24, 24 of the coupling portions 23, 23 and tightened.

Incidentally, each frame 17 constituting the auxiliary frame 16 configured as described above,
In the case of cutting 18 and 19 to fit the window frame 29 and connecting them to each other, the positioning bracket 27 as shown in FIGS. 8 to 10 is used in the illustrated embodiment. The positioning bracket 27 is formed into a crank shape in cross section by extruding an aluminum material or bending a steel plate. When positioning each of the frames 17, 18, and 19, the one end of the positioning bracket 27 is fixed to the corner bracket 20 by the screws 28 and 28 that are screwed into the screw holes 25 and 25, and the positioning bracket 27 The ends are brought into contact with the inner peripheral edge of the window frame 29 to position the frames 17, 18, and 19 described above.

Each of the frames 17, 18, and 10 positioned by the positioning bracket 27 as described above is cut into a predetermined length and further coupled to each other by the corner brackets 20 and 20 to be a window frame to which a surface lattice should be attached. The auxiliary frame 16 fits the size of 29.
When the frames 17, 18, 19 are positioned and the frames 17, 18, 19 are joined by the corner brackets 20 to form the auxiliary frame 16, the positioning bracket 27 is removed from the auxiliary frame 16.

The auxiliary frame 16 assembled as described above and from which the positioning bracket 27 has been removed is then made by extrusion molding an aluminum material and has a cross-sectional shape as shown in FIG. The plurality of connecting arms 30 fix the front surface of the window frame 29 parallel to the front surface of the window frame 29 at intervals. Both ends of the plurality of connecting arms 30 are cut along a plane perpendicular to the central axis of each connecting arm 30.

Guide grooves 32, 32 are formed at two positions on the inner peripheral surface of each coupling arm 30. These guide grooves 32, 32 are for guiding the tapping screws 31, 31 for connecting the auxiliary frame 16 and the window frame 29, and four guide grooves 32, 32 are formed at the corners of the corner bracket 20. Two small circular holes 33, 33 of the small circular holes 33, 33
It is compatible with. In addition, each frame 1 that constitutes the auxiliary frame 16
At the ends of 7, 18, 19 align with the guide grooves 32, 32 2
Small circular holes or notches for inserting the tapping screws 31, 31 are formed in the portions aligned with the individual small circular holes 33, 33.

To fix the auxiliary frame 16 to the window frame 29, the small circular holes or notches, the small circular holes 33, 33, and the guide grooves 32, 32 are placed on the outdoor side (the upper side in FIG. 1, the left side in FIG. 2). The tapping screws 31, 31 inserted from above are screwed to the front surface of the window frame 29. In this state, the plurality of connecting arms 30 are perpendicular to the back surface of the auxiliary frame 16 and the front surface of the window frame 29, respectively. Since the auxiliary frame 16 which is not partitioned by crosspieces is lighter in weight than the surface lattice main body 10, the work of connecting the auxiliary frame 16 to a predetermined portion of the front surface of the window frame 29 can be easily performed. In this way, the auxiliary frame 16
If fixed to 29, then the outer frame 14 of the surface lattice body 10,
It is fixed to the auxiliary frame 16.

In order to perform the work of fixing the outer frame 14 of the surface lattice main body 10 to the auxiliary frame 16, first, the protrusion 34 formed on the inner peripheral edge of the outer frame 14 is used.
The screw 37 is inserted from the inner peripheral side into the circular hole 35 formed in. Then, the screw 37 is screwed into the screw hole 25 formed in the folded wall 22 of the corner bracket 20 and further tightened (see FIG. 5). In this way, by connecting the surface lattice main body 10 to the auxiliary frame 16, the surface lattice main body 10 can be connected to a predetermined portion on the front surface of the window frame 29. Therefore, the heavy surface grid body 10 is attached to the window frame 29.
The work of connecting to a predetermined portion of the front surface of the can be easily performed.

In addition, when the width of the surface lattice main body 10 is wide and the supporting strength is insufficient only by supporting the corner brackets 20 and 20, only the sixth portion is provided in the intermediate portion between the upper frame 17 and the lower frame 18 forming the auxiliary frame 16. Fix the intermediate bracket 36 as shown in FIGS. Then, the intermediate bracket 36 and the window frame 29 are coupled by the coupling arm 30, and the outer frame 14 of the surface lattice main body 10 is also screwed to the intermediate bracket 36.

When the surface lattice of the present invention constructed as described above and fixed to the front surface of the window frame 29 is viewed from the outside, only the surface lattice main body 10 is visible. The auxiliary frame 16 connected to the back surface of the outer frame 14 forming the surface lattice, and the connecting arms 30, 30 vertically connected to the back surface of the auxiliary frame 16 are exposed outward or inward from the surface lattice. There is nothing. Therefore, the appearance of the surface lattice is not bad.

Further, by using the positioning brackets 27, 27 at the time of assembling, it becomes possible to easily and surely position each component member.

(Effect of the Invention) Since the surface lattice of the present invention is constructed and operates as described above, not only the work of connecting the heavy surface lattice main body to a predetermined portion of the front surface of the window frame can be easily performed, but also wasteful. There is a great practical effect that the surface lattice can be attached easily and easily without using any special material.
