In the present invention, left and right base supports are provided with a plurality of supporting points (rotating shafts) at appropriate intervals, and left and right, except for the U-shaped frame with one end fixed, are sequentially arranged in parallel with the fixed U-shaped frame. A fan-shaped rotatable U-shaped frame extending from left and right fulcrums is provided, a net is suspended so as to connect the plurality of U-shaped frames, and at least the fixed U-shaped frame is fixed. This is a net cover system with a torsion spring that has a counterbalancing reaction force against the rotational moment caused by the weight of the U-shaped frame at the other end and the cover, and can be easily opened and closed even for large ones. In addition, since a plurality of U-shaped frame bodies are provided on the base support body with fulcrums at appropriate intervals, compared to the storage capacity in the case of a circular cross section centered on one point like a normal fan shape. The cross section is almost elliptical, and the installation height is particularly limited In the same footprint case that, a garbage bag packed volume efficiently increase can be secured. In addition, the torsion spring can support the weight of the U-shaped frame and the cover so that it can be easily opened and closed with a soft touch. In addition, since it can be folded compactly after garbage collection is completed, it is a net cover system that has excellent aesthetics as well as efficient collection work.

Hereinafter, an embodiment will be described with reference to the accompanying drawings. FIG. 1 is a perspective view showing a state in which the net cover system 1 is closed, and a plurality of fulcrums (rotating shafts) C1, C2, C3 and C1 ′, C2 ′, C3 at appropriate intervals on the left and right base supports 2a, 2b. A U-shaped frame 5-1 formed by fixing a connecting column 4-1 between the tip ends of columns 3-1a and 3-1b extending from fulcrums C1 and C1 '; A U-shaped frame 5-2 formed by fastening a connecting support column 4-2 between the ends of the support columns 3-2a and 3-2b extending from the support points C2 and C2 ′, and the support points C3 and C3 A U-shaped frame 5-3 formed by fastening a connecting column 4-3 between the ends of the columns 3-3a and 3-3b extending from the base, and fixed portions Cx and Cx ' Connected between the tips of the support columns 3-4a and 3-4b, which are fixedly attached to the rotating part, which is one of the components constituting the supports 2a and 2b. A U-shaped frame 5-4 formed by fixing the support 4-4 is formed, and the U-shaped frame 5-4 is sequentially arranged in parallel except for the U-shaped frame 5-4. The net 6 is suspended so as to connect the U-shaped frame members 5-1, 5-2, 5-3, and 5-4 that are rotatable in a fan shape extending from the left and right fulcrums, and at least the fixed The net cover system 1 is provided with a torsion spring having a rotational moment that counteracts the rotational moment due to the weight of the U-shaped frame 5-1 at the other end facing the U-shaped frame 5-4. The large net cover system 1 can be easily opened and closed, and the base supports 2a and 2b are provided with fulcrums at appropriate intervals to provide a plurality of U-shaped frame bodies. In the case of the present invention, compared to a circular opening / closing method centered on one point, Since the 閉方 formula, at the installation location of the height limitations, the garbage bag packed volume efficiently increase can be secured. FIG. 2 shows a side view of the net cover system in an opened state. In the figure, A... A 'indicates a height limit line. In FIG. 2, the tips S1, S2, and S3 of the columns 3-1a, 3-2a, and 3-3a when the net cover system is opened are closed when the net cover system is closed (when the garbage bag is surrounded by the net cover system). In the same manner, it is rotated to T1, T2, and T3 by connecting to the net 6, respectively. At this time, when the fulcrum C1, C2, C3 of each column and the position of the column fixing portion center Cx are opened and closed in a fan shape by appropriately shifting as shown in the figure, such as C1-C2, C2-C3, C3-Cx, Since the inner volume can be increased due to the elliptical shape, the dust accumulation volume is increased within the limit height limit. By the way, in the case of Cx, where the fulcrum of each column is a single point as in the normal method, S1, S2 and S3 face each other and turn to T1 ′, T2 ′ and T3 ′. Compared to the case, the volume corresponding to the cross-sectional area difference W of the shaded portion is small. However, in the case of the present invention, although the height restriction is cleared, there is a drawback that the length between C1 and Cx in the figure is longer, but the installation conditions It can be said that there is a great merit in that it is possible to expand the garbage storage capacity. Next, FIG. 3 shows a detailed cross-sectional view of the bearing portion of the net cover system base support body at the B portion of C2 among the fulcrums C1, C2, C3 and C1 ', C2', C3 'of FIG. In FIG. 3, the base support 2 a is fixed to the U-shaped block 13 with the tip screw bolts 8 inserted into the bearings (or metals) 7 a and 7 b and the inner periphery receiving block 14 of the torsion spring. The metal rings 11a and 11b are fitted and fixed to the outer peripheral surfaces of the bearings (or metals) 7a and 7b, respectively, and the support 3-2a is fixed to the metal rings 11a and 11b by appropriate means such as welding. 12 b is fixedly extended, and the hook portion 9 a at one end of the torsion spring 9 is engaged with a spring locking hole 9 a ′ provided at the bottom of the column 3-2 a, while the hook portion 9 b at the other end of the torsion spring 9 is engaged. It engages with a locking hole 9 b ′ provided in the U-shaped block 13. A washer 10 is provided between the side portions of the U-shaped block 13 and the bearings (or metals) 7a and 7b to promote slipperiness. As described above, the column 3-2a is freely rotated with respect to the U-shaped block 13 while receiving the torsional reaction force of the torsion spring 9. Also, the columns 3-1a, 3-2a, 3-3a and 3-1a ', 3-2a', 3-3a 'operate in the same manner when the torsion springs are provided in the same manner as described above.

More specifically, the pitch intervals of the fulcrums C1, C2, C3, Cx or C1 ′, C2 ′, C3 ′, Cx ′ of the base supports 2a, 2b shown in FIGS. Thus, the shape suitable for the installation location of the net cover system 1 can be selected. The torsion spring 9 is mainly composed of a plurality of U-shaped frames connected by a net due to the weight of the U-shaped frame 5-1 (5-2, 5-3 if necessary) and the weight of the net. Provide a reaction force in a direction against

The rotational moment due to the weight and net weight is determined by the angle with the horizon of the U-shaped frame. It is required to appropriately select the spring constant of each spring. That is, when designing the spring, it is desirable to make the spring constant as small as possible within the allowable stress. As a result, the cover is soft and easy to operate, and it is safe and dust-free by designing it to move gently without causing the U-shaped frame 5-1 to jump up rapidly due to the reaction force of the torsion spring. Large cover volume, easy to fold, excellent net cover system for bird, beast and wind damage countermeasures.
