Description

[Detailed description of the invention] This invention relates to an aluminum fence, and provides a fence with high overall rigidity by strengthening each fixed state of the horizontal and vertical bars with a simple structure. This is what I am trying to do.

An embodiment of the present invention will be described below with reference to the drawings.

In the figure, 1 indicates a left vertical frame (not shown), a right vertical frame 3 made of aluminum shapes, upper and lower horizontal bars 2, 2 made of aluminum shapes installed between the left and right vertical frames 3, and the horizontal bars 2, 2. This is an aluminum fence configured with a plurality of vertical bars 4 attached to the fence.

The horizontal beams 2, 2 are formed by integrally protruding projecting pieces 5, 5 having a cross section in the vicinity of one of the vertical walls 15, 15 of the opposing walls 6, 6 facing each other. It is integrally molded with an extruded aluminum material having hollow portions 7, 7 formed by forming opening recesses 13, 13 with the substantially protruding pieces 5, 5, respectively.

The plurality of small vertical bars 4 attached to the upper and lower horizontal bars 2, 2 are made of aluminum castings with decorative patterns, aluminum extrusion materials, etc., and are longer vertically than the upper and lower horizontal bars 2.2 a. It is formed to a length of .

Each small vertical bar 4... is connected to the tip protrusions 12, 12 of the abbreviated protrusions 5, 5 of the upper and lower horizontal bars 2, 2, and one of the vertical walls 15, 1.
5 are brought into contact with each other across the opening recesses 13, 13, respectively, and the abbreviated protrusions 5.5 of the upper and lower horizontal bars 2, 2 and the small vertical bars 4.・Tighten and fix.

Incidentally, in this embodiment, the right vertical frame and the left vertical frame (not shown) face each other at the opposing surfaces 8 and the front wall 9 and the rear wall 10, respectively, and integrally form a fitting groove 11 having a substantially U-shaped cross section in the longitudinal direction. The cut ends of the upper and lower horizontal bars 2゜2 are inserted into the approximately U-shaped fitting grooves 11 of the left and right vertical frames 3, respectively. , for example, is tightly fitted and fixed via a joint block (not shown), etc.
At this time, the protruding end portions 12.degree. 12 of the abbreviated protruding pieces 5, 5 are brought into contact with the rear wall 10 of the fitting groove 11, and rotation is prevented.

It should be noted that the present invention is not limited to the above-mentioned embodiments, and it goes without saying that the specific shapes and structures of the vertical frames, horizontal bars, vertical bars, etc. can be changed in various ways as long as they do not go against the gist of the present invention. It is.

As described above, the present invention integrally protrudes protrusions with a short cross-section near one of the vertical walls of the opposing walls of the horizontal beam, and forms an opening recess with the opposing walls and the short protrusions. Formation waist The plurality of vertical bars are made longer than the upper and lower horizontal bars, and the tip protrusion of the abbreviated protrusion and one vertical wall are brought into contact with each other across the opening recess, and screws, etc. Since it is tightened and fixed to the upper and lower horizontal bars using a fixing device, the vertical small beam comes into contact with the tip protrusion and one of the vertical walls at two places, and is pulled and pressed by the fixing device and is tightened and fixed. Each of the fixed parts with the horizontal bars is strengthened, and rotation of the vertical bars is effectively prevented, increasing the rigidity of the fence as a whole.

In addition, the number of places where fixing devices are used can be reduced, making it easier to manufacture the fence, and since the horizontal and vertical bars are made of aluminum profiles, they are easy to form, and rust does not occur. This also prevents the strength from decreasing.

5...L-shaped protrusion.

Claims (1)

[Scope of utility model registration request] Left and right vertical frames 3 made of aluminum shapes, upper and lower horizontal bars 2.2 made of aluminum shapes installed between the vertical frames 3, and a plurality of small vertical bars 4 attached to the horizontal bars 2, 2.・In the fence, protrusions 5, 5 having a cross-sectional shape are integrally provided in the vicinity of one vertical wall 15, 15 side of the mutually opposing opposing walls 6, 6 of the horizontal bars 2, 2. The opposing walls 6, 6 and the substantially-shaped protrusions 5°5 form opening recesses 13, 13, respectively, and the plurality of vertical bars 4 are made vertically longer than the space between the upper and lower horizontal bars 2, 2. At the same time, the tip protrusions 12 and 12 of the roughly shaped protrusions 5, 5
and one of the vertical walls 15, 15, respectively, by straddling the frontage recesses 13, 13, and by means of fixing devices 14.14, the vertical walls 5.5 and 5.5 of the upper and lower horizontal bars 2, 2 are connected vertically. This tossuru aluminum fence is characterized by its four small crosspieces being tightened and fixed.
