Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage storage device, and more particularly to a device for fixing a net for separating garbage so that a crow or a cat does not catch the garbage in a garbage storage place on a city or a pavement.

[0002]

2. Description of the Related Art Conventionally, as a measure against crows, cats, etc., it is convenient to put a net directly on a garbage bag in a garbage storage area, and therefore it is used in many places. But,
This method is not a sufficient countermeasure because there is a problem that the net can be caught through the net because the net is in direct contact with the garbage bag. There is one in which a net is formed into a bowl shape that is laid down using a frame such as a thick wire, and a gap is formed by inserting a spacer between the garbage bag and the net (Japanese Patent Laid-Open No. 10-129802). There is a problem that it is difficult to operate if it is large and large. On the other hand, there is one in which a net is held by a frame in the shape of a box having a door or lid that can be opened and closed, and a dust bag is placed inside the frame (Japanese Patent Laid-Open Nos. 6-255701 and 9-95).
47214, JP-A-9-309601). This structure is effective, but such permanent equipment occupies a lot of space, and the collection staff of the cleaning department needs to collect the waste through the lid or the door when collecting the waste, which reduces the collection efficiency.
In addition, there is a problem that the installation place is largely occupied. On the other hand, not only is the net held by a frame in the form of a box having a door or lid that can be opened and closed so that it can be folded after collecting garbage, but it can be folded after collecting garbage. There is one in which a body is divided into a front part and a rear part and joined by a hinge, and a pulley is provided at the front part so as to be foldable (Japanese Patent Laid-Open No. 2001-2001).
122401). This structure is effective, but the collection staff of the cleaning department needs to collect the waste through the lid or door when collecting the waste, so the collection efficiency is reduced, and the operation for folding and unfolding is troublesome. There is also a problem that the device becomes complicated.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a net holding device which is effective against crows and the like and which can be miniaturized so as not to interfere with the collection of dust and not to interfere with the passage of waste after collection. To aim. It is also an object of the present invention to provide a net support device that is safe even if accidentally touched by a passerby and therefore safe.

SUMMARY OF THE INVENTION The present invention comprises a horizontal support frame, a plurality of net holding arms, and a connecting device for attaching the arms to the horizontal supporting frame at predetermined intervals, the connecting device being the holding device. Provided is a net support device for a garbage storage, which has a pivoting means for pivotally moving an arm in a vertical direction and a stopper for fixing the arm in a horizontal position and at least one upper position. In a preferred form, the pivot means further comprises means for allowing the retaining arm to pivot horizontally in the horizontal position. In a more preferred form, the net holding arm is formed of a spring wire into an elongated flat plate shape so as to be rigid in the vertical direction and flexible in the horizontal direction.
In this more preferable form, the net holding arm does not need to pivot in the horizontal direction, and the pivoting means may have a pivot for pivoting the holding arm only in the vertical direction. More preferably, the net holding arm is formed in a substantially U shape, and both legs of the net holding arm are fixed to the pivot member. In addition, the U-shaped holding arm may have a reinforcing rib to reinforce the rigidity in the vertical direction. In each of the above embodiments, the horizontal support frame may be held on the wall surface, or if it cannot be held, it may be held by a stand.

[0005]

DETAILED DESCRIPTION OF THE INVENTION the present invention will be specifically described with reference to the configuration now to the figures. FIG. 1 shows a net supporting device for supporting a net 30 knitted from a synthetic resin string or the like in a garbage storage according to an embodiment of the present invention, which is supported by a stand composed of columns 7 standing upright from a base plate 8, Alternatively, as shown in FIG. 2, a horizontal support frame 1 directly attached to the wall surface, a plurality (three in this example) of net holding arms 2, and a connecting tool 3 for attaching the holding arms 2 to the horizontal support frame at predetermined intervals. And consists of. The holding arm 2 is bent in a U-shape from the spring wire 21 so as to be rigid in the vertical direction and flexible in the horizontal direction, and is formed in an elongated flat plate shape as a whole. Reinforcing ribs 22 may be provided to reinforce the spring wire 21. Since this plate-shaped surface is arranged vertically, it has sufficient rigidity to stably support the net 30, but it can flex freely in the horizontal direction and flexes left and right even when touched by a person. It is superior to the rigid ones, as it does not hurt people. The base of the holding arm 2 is fixed to the lateral member 24 by welding or the like, and the plurality of holding arms 2 can be integrally pivoted in the vertical direction.

As shown in FIGS. 3 and 4, the coupling 3 has a mechanism for allowing the holding arm 2 to pivot in the vertical direction, and has a plate-like fixed side pivotal attachment fixed to the horizontal support frame 1 side. Member 31 and
And a movable side pivot member 32 fixed to the lateral member 24 (FIG. 2) at the base of the holding arm 2. The fixed side pivot member 31 defines a pivot pin 35 that allows the holding arm 2 to rotate, a stopper pin 33 that defines the horizontal position and upper position of the holding arm 2, and a lower position of the holding arm 2. Is provided with a stopper pin 34 to move the movable side pivot member 3
2 is provided with a long hole 36 into which the pivot pin 35 is fitted, a stopper projection 38 that is locked to the stopper pins 33 and 34, and further has a locking surface 39 that defines the upper position. The lowered position does not have to be fixed, but if the stopper pin 34 is used to fix the position, the position is stabilized. The above embodiment is an example in which a stand is used. However, if there is a wall surface that can be fixed, the stand is not necessary, and it is more space to directly fix the horizontal support frame 1 to the wall surface as shown in FIG. It can be used widely. Alternatively, a lower enclosure 10 may be used to define the front of the net. It is also possible to provide clips for fixing the net at several places on the holding arm 2 and / or the transverse member 24.

Operation In the above structure, it is assumed that the net holding arm 2 is in the horizontal position as shown in FIG. At this time, as shown in FIG. 3, the stopper pin 33 is engaged with the stopper projection 38, and the holding arm 2 is in a horizontal state. In this state, when there is a net 30 whose bottom is released or a wall surface, the holding arm 2 is covered with the net 30 whose bottom is released and no back is present.
When supported by, the space for storing the garbage bag is formed.
To put the garbage bag in the net, lift the hem of the net. On the other hand, when the worker takes out the rubber bag for collection, the holding arm 2 is pushed upward together with the net. As a result, the movable side pivot member 32 rotates and moves to the position of FIG. 4, and the engagement surface 39 is locked to the stopper pin 33. In order to obtain this action, the pivot pin 35 and the long hole 36 in the state of FIG.
When a gap is formed between the movable arm 32 and the upper end of the movable arm 32, the movable side pivot member 32 is moved by the weight of the holding arm 2 and the net at the position of FIG.
Is pushed downward, so that both can be reliably locked. To return from the upper position in FIG. 4 to the horizontal position, simply hold arm 2
You just have to pull it horizontally. When it is desired to lower the net lastly, if the holding arm 2 is pulled forward, the movable side pivot member 32 is guided by the elongated hole 36 and moves forward, so that the stopper projection 38 is disengaged from the stopper pin 33. The arm 2 swings downward, the stopper projection 38 is locked to the stopper pin 34 as shown in FIG. 5, and the net is also lowered accordingly.

In the above, when the user or passerby touches the holding arm 2 in the horizontal state of FIGS. 1 to 3, there is a risk of injury if the holding arm 2 is rigid, but like the present invention. If the holding arm is made of a spring material, there is no risk of injury and it is safe.

In the following modified example of the present invention, a rigid one may be used as the holding arm 2. In that case, the base lateral member 24 of the holding arm 2 is shaken in the horizontal direction of the holding arm 2. It must be supported by a pivoting member that allows movement. However, the structure of this embodiment is preferable because not only the structure becomes complicated as compared with the above embodiment but also the stability of the net support is lowered. Furthermore, FIG.
The pivot mechanism shown in 5 may have a universal structure that can be fixed at any raised position. Such pivoting mechanisms are commercially available.

6-7 show a connector 4 according to another embodiment. This coupling tool includes a fixed disc 40, a threaded shaft 45 that stands upright from the center thereof, a movable disc 41 fitted to this shaft, and a dish washer 4 that holds down the movable disc 41.
3 and a nut screwed into the threaded portion of the shaft 45 so as to press the dish washer 43. The fixed disk 40 and the movable disk 41 have a plurality of protrusions 46 on the opposite surfaces.
(8 in this example), and the movable disc 41 can be fixed at a relative angular position to each other by pressing the movable disc 41 against the fixed disc 40. The fixed disk 40 is fixed to a wall surface, a support, or the like by a holding fitting 42. On the other hand, a holding arm 20 similar to that shown in FIG. 1 is fixed to the movable disk 41 by welding or the like. With this structure, the holding arm can be fixed at a plurality of arbitrary angular positions. Further, when the movable disk 41 is rotated around the axis 45, the angle of the hair can be cut by the action of the dish washer 43, and the changed angle can be maintained by the dish washer.
