Abstract

PROBLEM TO BE SOLVED: To make mass production possible while improving the economicaly efficiency by a method wherein four rails that can be slidably fitted one another are connected with one another at their ends and a frame having two paralleled sides and being easily variable in shape and size is formed. SOLUTION: Four rails 1-4 that can be slidably fitted one another are connected with one another at their ends, and a litter net attaching frame 100 having paralleled opposite two sides is formed. The frame 100 can be variable in size by sliding the paralleled two sides in the lengthwise direction. After the frame 100 is set to a specified size, fixation is made by a fixing means such as caulking, and a litter receiving net is hung at the end of its opening on the periphery of the frame 100. As the litter net attaching frame 100 can be easily varied in shape and size in accordance with shape and size of a grease trap, the frame can be easily produced in mass production, and is economical.

As shown in FIG.
A partition 54 is inserted in the inside, and one side of the partition 54 is fixed to an inner wall 53 as shown in FIG.
a and 51b, and the other side is sandwiched by partition guides 51c and 51d, and the partition 54 is detachable from the green strap 200.

As shown in FIG.
Flanges 53a, 53b, and 54b are fixed to the inner wall 53, and a flange 54a is fixed to the partition 54 so that the height of the upper surface is the same.

The garbage net mounting frame 100 can change the size of the rectangle in FIG. 1 by sliding each guide with respect to each rail.
The lower surfaces 105 to 108 shown in FIG. 3 are placed on the upper surfaces of 3a, 53b, 54a and 54b,
The garbage net mounting frame 100 is mounted in 00.

Each guide can be adjusted by sliding in the directions of arrows A and B in FIG. 3 in accordance with the shape and size of the space partitioned by the inner wall 53 of the grease strap 200 and the partition 54.

After adjusting each guide to the size partitioned by the inner wall 53 and the partition 54 of the grease strap 200, the upper flanges 1a, 1a, 1
b and the first guide 5 are caulked with pliers, and are engaged with the flanges 5a and 5b of the first guide 5 to make it impossible to slide. Each rail and each guide are caulked in the same manner as the first rail 1 and the first guide 5 so as not to slide.

When each guide is not slid on each rail but swaged at a position where the size of the space 100a (FIG. 1) is minimized, the mesh size is 0.5 to 4 m.
m (preferably 2 mm) of the opening edge of the mesh bag 52 (FIG. 5) is formed on both ends 91a and 91b of the first rail 1 shown in FIG.
It is hooked on both ends 92a and 92b of the rail 2 and receives dirt and sewage flowing into the space 100a shown in FIG.

When each guide or one of the guides is slid with respect to each rail and then the respective rails are caulked to fix the position of the guide, the opening edge of the mesh bag becomes the first guide 5 in FIG. The upper right end 95, the lower right end 96 of the second guide 6, the upper left end 97 of the third guide 7, and the lower left end 98 of the fourth guide 8 as viewed.
Hook on

As the dirt accumulates in the mesh bag, the opening edge of the mesh bag is dragged toward the space 100a.
f, 2e, 2f, 3a to 3e, and 4a to 4e, and are firmly held.

When dirt accumulates in the net bag and is clogged, the handles 20a and 20b (FIG. 1) are held, and the net bag (not shown) is removed from the grease strap together with the garbage net mounting frame 100. When the bottom of the net bag touches the ground, there is a possibility that dirt may come out of the opening of the net bag, but the legs 32 and 33 shown in FIG.
Have the function of preventing the bottom of the mesh bag from touching the ground when the garbage net mounting frame 100 is placed on flat ground such as the ground. 4 and 5, the length of the legs 31 to 34 in the vertical direction is set in accordance with the accumulated amount of filth stored in the mesh bag.

Each rail and each guide may be bonded with an adhesive other than caulking, or may be welded if made of steel.
Further, it may be fixed with bolts and nuts.

[0028]

According to the present invention, a garbage net mounting frame corresponding to various shapes and sizes of various grease straps can be easily manufactured with a small number of members.

Since the shape and size of the frame can be changed according to the shape and size of the grease strap, mass production is easy and economical.

If an elastic net is used, it is possible to cope with a garbage net mounting frame of a different size, and it is not necessary to prepare a non-elastic net corresponding to the size of the frame each time.
