Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a garbage container that is installed at an appropriate location in a city to collect garbage generated from each household.

[Conventional technology]

In a dust container opening/closing device as shown in Utility Model Application No. 48-44768, in order to cushion the shock when the bottom plate opens, a torsion rod consisting of a spring bar is installed on one side of the lower flat bar of the container body on the hanging side in the longitudinal direction. Attach the torsion part, bend its base end as appropriate and fix it in the appropriate place on the frame, bend its tip part downward, and then pass it through the through hole at right angles to the torsion part and bend it toward the opening side and attach the lid. A bolt is provided that extends along the lower surface of the body, a covering such as a plastic tube is provided on the bolt, and the end of the bolt is fixed at a proper place on the lower surface of the lid body with a fastener. Already proposed. In this proposal, torsion rods are attached to both sides of the bottom plate from the proximal end, so that the impact when the bottom plate opens is absorbed by the spring force of the torsion rods alone. However, with such a structure, there is a limit to the spring force of the torsion rod, and sufficient shock-absorbing force cannot be obtained.

[Problem to be solved]

The present invention attempts to improve the buffering force of a spring member such as a torsion rod used to buffer the bottom plate of the conventional dust container when it is opened.

[Technical means to solve problems]

The technical means of the present invention are as follows.

In a garbage container in which the bottom plate is opened by rotating around a rotation shaft fixed to the main body, a mounting angle 10 protrudes from both sides of the bottom plate 2, and a base end thereof is attached to an opening flange 8a of the angle 8 at a fixing point 1.
2a, 13a, and the tip portions of the bar springs 12, 13 are fixed at the U-shaped tip portions 12c, 13c, and the tip portions form the U-shaped tip portions 12c, 13c. These bar-shaped springs 11 cross each other starting from fixed points 12a and 12b, and then touch the bearings 1 on the bottom plate of the rotating shaft 11, respectively.
4, and its tip U-shaped portion 12c, 1
3c is inserted into the base end of a flat bar 9 attached to both sides of the bottom plate 2 in a two-point supported manner, and the tip end of the flat bar 9 is inserted and supported by the mounting angle 10 on both sides of the bottom plate 2.

[Effect]

In the dust container of the present invention, when the bottom plate 12 is opened, the bar-shaped springs 12, 13 and the inner parts of the bearings 14, 14 function as supporting members, similar to the roots of a tree extending deep into the ground. Therefore, the inner portions of the bearings 14, 14 serve as support base portions for the tip U-shaped portions 12a, 13a, and the elasticity of the outer portions of the bearings 14, 14 of the cantilevered bar-shaped springs 12, 13 remains, resulting in a strong flat bar 9
can support.

S: A spring whose both ends are attached to the main body 1 and the second handle 4 and which pulls the second handle 4 toward the main body 1.

The operating state will be explained below.

Closed state of the bottom plate 2 When the bottom plate 2 is closed, the first hook 3 of the first handle 3 and the second handle 4 are closed as shown in FIG.
b, the second hook 4b is the first closing pin 6 of the bottom plate 2;
They are respectively engaged with the second closing pins 7 by the traction force of the springs s.

Opening the bottom plate 2 In the drawing, move the first handle 3 to the right, or move the second handle 4 to the right as well.
Alternatively, when rotating around the second pivot shaft 4a, the first hook 3a and the second hook 4b are disengaged from the closing pins 6 and 7, as shown in FIG.
will be opened.

Attachment structure of the bottom plate 2 (FIG. 4) The bottom plate 2 is attached to the main body 1 by the structure shown in FIGS. 4a and 4b.

That is, flat bars 9, 9 are provided on both sides of the bottom plate 2.
are carried by the mounting angles 10, 10, and the flat bars 9, 9 are connected to the angle 8 of the main body 1 via bar springs 12, 13.

In FIG. 4a, 12a, 13a are the fixing points of the bar springs 12, 13 to the angle 8, 12b, 1
3b is a support plate.

Reference numerals 12c and 13c are U-shaped ends of the bar springs 12 and 13. Further, the rotation shaft 11 of the bottom plate 2 is inserted and supported by bearings 14, 14.

In addition, since flat bars 9, 9 are attached to both sides of the bottom plate 2, when the bottom plate 2 is opened, the bar-shaped springs 1
The bottom plate 2 hangs down against the elastic forces 2 and 13. As a result, the impact when the bottom plate 2 hangs down is significantly reduced.

By the way, the bar springs 12 and 13 have fixed points 12
b, 13b as the starting point, after crossing each other, it is inserted into the bearing 14, and the U-shaped portion 12c, 1 at the tip thereof is inserted into the bearing 14.

In addition, the tip U-shaped portions 1 of the bar springs 12 and 13
2c and 13c are biased in the direction of closing the bottom plate 2,
Since the flat bars 9, 9 are suspended around the periphery of the main body angle by bar springs 12, 13, the bottom plate 2
When it opens as shown in Figure 4c due to the weight of the garbage,
Although the flat bars 9, 9 are once opened vertically in the direction of arrow D (FIG. 4), due to the tension of the bar springs 12, 13, the flat bars 9, 9 return to a somewhat horizontal position and rotate. When the flat bars 9, 9 rotate back, the mounting angle 10 integral with the bottom plate 2 supporting the flat bars 9 also rotates back in the direction of the arrow H, and is maintained at an angle α smaller than the right angle. Since it rotates back to the angle α in this way, when the garbage container of the present invention is suspended and touches the ground, the bottom plate 2 automatically rotates nearly horizontally in the direction of arrow C, allowing automatic closing.

[Description of Second Embodiment] Next, the second embodiment shown in FIGS. 5 and 6 will be described.

The second embodiment is similar to the first embodiment in the installation of the flat bar 9, but the operating system of the first handle and the second handle is as follows.
This embodiment differs from the first embodiment in that second intermediate levers 108 and 109 are inserted.

First, each member shown in FIGS. 5 and 6 will be explained.

110: Connection axis 111: Connection axis 112: Connection axis 113: Connection axis 114: First closing pin 115: Second closing pin S: Spring that fixes one end to the main body 101 and pulls the second engaging element 106 116: Main body 101 is an angle attached to the lower edge, and has an angle surrounding protrusion 16a at the lower end.

Next, its operating state will be explained.

The closed state of the bottom plate 102 (FIG. 5) FIG. 5 shows the closed state of the bottom plate 102, in which the first and second engagers 10 are
5,106 first and second hooks 105b, 106
b is engaged with the first and second closing pins 114 and 115.

In the second embodiment, when the bottom plate 102 is closed, the first intermediate lever 108, the interlocking lever 107, and the second intermediate lever 109 are positioned in a straight line.

Opening of the bottom plate 102 (Fig. 6) In the state shown in Fig. 5, when the first handle 103 is rotated to the right, the first intermediate lever 108 is pushed to the left, and its connecting shaft 111 is moved to the left. do. As a result, the first engaging element 105 rotates to the left about the first engaging element pivot shaft 105a, and is unclosed from the first closing pin 114. At the same time, the interlocking lever 107 also moves to the left, so the connecting shaft 113 also moves to the left. Thus, the second engager 1
06 rotates to the left about the second engaging element pivot 106a, and is released from the second closing pin 115.

Further, the second intermediate lever 109 also moves to the left, and the second handle 104 rotates to the right.

Second handle 1 instead of first handle 103
Even if 04 is rotated to the right, the first and second engagers 1
05, 106 and the first and second closing pins 114, 11
5 is released, and the bottom plate 102 is opened.

In the second embodiment, the first and second intermediate levers 10
8,109 are the first and second handles 103,104
and the first and second engaging members 105 and 106, the force for pushing the first and second handles 103 and 104 is light.

[Effect of the invention] When the garbage container of the invention opens the bottom plate, the U-shaped tip portions 12c, 13c of the bar springs 12, 13
is biased in the direction of closing the bottom plate, so the shock when the bottom plate opens can be significantly reduced.

In the present invention, the bar-shaped springs 12 and 13 start from the fixed points 12a and 13a, cross each other, pass through the bearing 14, and then are inserted into the base end of the flat bar 9.

Therefore, the bearings 14 of the bar springs 12, 13
The supporting force of the bar-shaped springs 12, 13 against the flat bar 9 of the U-shaped portions 12c, 13c remains strong in the inner part.

That is, since the bar-shaped springs 12 and 13 intersect inwardly toward the bearing 14, the inner portion of the bearing 14 can have a sufficient length. If the fixing points 12a, 1
If position 3a is selected, the inner portion of the bearing 14 will be shorter, and the supporting force of the bar springs 12, 13 against the flat bar 9 will not be large enough.

Since the tip U-shaped portions 12c and 13c are folded back and support the flat bar 9 at two points, the supporting force of the bar springs 12 and 13 to the flat bar 9 is reliably transmitted.
