Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention provides a garbage container equipped with an opening/closing lid that is pivotally connected to the upper edge opening of the container body.
The present invention relates to a lid opening/closing device for opening and closing the opening/closing lid.

(Prior art) Conventionally, the lid opening/closing device for this type of garbage container is
Generally, as shown in Fig. 6, the middle part of a foot lever B is pivotally attached to the bottom of the container body A, and the lower end of the operating lever D is rotated to the tip of the foot lever B. While freely interlocking E, the upper end of the operating lever D is engaged with an appropriate part on the pivot joint G side of the opening/closing lid F, and a petal H is fixed to the base end (projecting end) of the foot lever B. By stepping on this petal, the operating lever D is raised, and the upward movement of the operating lever D is transmitted to the opening/closing lid F to open the lid F, and by releasing the pedal H, the lid F is opened. The lid F is configured to be closed by lowering the operating rod D using the weight.

(Problems to be Solved by the Invention) However, the above conventional device has the following problems.

In other words, in the conventional device, when the opening/closing lid closes under its own weight, no consideration is given to any means for regulating the downward movement of the opening/closing lid, so when the foot is removed from the petal, the opening/closing lid closes with force and It becomes elliptical and closes. Therefore, when the opening/closing lid is closed, it not only strongly impacts the upper edge of the container body and generates noise, but also causes excessive force to be applied to the hinge part of the lid, causing play, etc. had the problem of shortening the lifespan of the

In addition, in the conventional device, the opening/closing lid is pushed up and opened via the operating rod using only the force of pressing the petal, so it is necessary to press the petal strongly, and this pressing force is applied to the container body, resulting in an undesirable effect. When I stepped on the pedal hard to prepare, the momentum caused the garbage container to tilt forward and cause it to tip over.

Additionally, depending on the installation location (such as a narrow space), it may be desirable to have a garbage container that is vertically long (narrow in width). , the moment when stepping is large, and therefore, the conventional system of pushing up the lid using only the force of stepping is not suitable for vertically long garbage containers.

Furthermore, in the conventional device, it is preferable to make the weight of the opening/closing lid as light as possible, and therefore, there is a problem in that the opening/closing lid must be made thin and restrictions are placed on the materials, etc.

The present invention was developed in view of the above-mentioned problems of conventional devices, and one of the purposes of the present invention is to provide a lid opening/closing device that closes slowly while applying a brake to the opening/closing lid. It is in a place where we provide.

Another object of the present invention is to provide a lid opening/closing device that allows the opening/closing lid to be opened easily and smoothly by simply stepping on a foot lever.

(Means for Solving the Problems) The structure of the present invention for solving the above problems will be explained using FIGS. 1 to 5, which correspond to the embodiments. In a garbage container equipped with an opening/closing lid 2 which is pivotally attached 3 to the edge opening, the upper end is linked 7 to an appropriate part on the pivoting part 3 side of the opening/closing lid 2 so that it can be vertically moved up and down into the container body 1. The operating rod 6 is disposed horizontally in a swingable manner on the bottom of the container body 1 with its tip linked 9 to the lower end of the operating rod 6, and its rear end is disposed with its rear end protruding outside the container body 1. By stepping downward on the opening/closing lid 2, the operating rod 6 is raised to open the lid, and by releasing the protruding end, the operating rod 6 is lowered by the weight of the opening/closing lid 2 to close the lid. The foot lever 8 is equipped with a foot lever 8 configured as shown in FIG. By stepping on the protruding end of the rear end, the operating rod 6 is assisted by the action of the spring 16 to push up the opening/closing lid 2 and open the lid. A brake bushing 20 made of synthetic resin is fitted into the operating rod 6 at a position corresponding to the insertion hole 19, and is inserted into the insertion hole 19 formed in the receiving frame body formed near the upper edge. The bushing 20 is configured to slide into contact with the edge of the insertion hole 19 when the operating rod 6 is lowered.

(Operation) The present invention described above operates as follows. Now, in the state shown in the first figure, the protruding end of the foot lever 8 (petal 1
4) (see the imaginary line diagram in Figure 1), the tip of the foot lever 8 swings upward, so the operating lever 6 moves to the fifth position.
The actuating rod 6 is pushed upward as shown by the solid line from the imaginary line in the figure, and this upward movement of the operating rod 6 is transmitted to the opening/closing lid 2, which opens the lid. When the pedal 14 is released, the lid 2 uses its weight to lower the operating rod 6 and close it. When the operating rod 6 is lowered, the bush 20 of the operating rod 6 is inserted into the insertion hole of the receiving frame 5. 19 hole edge 1
Since it comes into sliding contact with 9a, the operating rod 6 slowly descends while being braked. Therefore,
The lid 2 is quietly closed by the action of the brake.

Further, the tip of the foot lever 8 is constantly receiving an upward pulling force due to the action of the spring 16, but at the same time, the weight of the opening/closing lid 2 is applied to the tip of the foot lever 8 via the operating rod 6. . Therefore, when the petal is released, the foot lever 8 is moved by the spring 1 due to the weight of the lid 2.
6, the lid 2 is closed (see FIG. 1).

Now, in the state shown in FIG. 1, when the pedal 14 is depressed (see the imaginary line in FIG. The upward movement is transmitted to the opening/closing lid 2 to open the lid, but on the other hand, the operating rod 6
Since the tip side of the lid 2 is constantly being pulled upward by the spring 16, the lid 2 is pushed up by the operating rod 6 while being assisted by the force of the spring 16. Therefore, it becomes possible to reduce the force required to press the pedal 14.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings. 1 to 5 show a lid opening/closing device for a garbage container, which is an embodiment of the present invention. In these figures, reference numeral 1 denotes a container body formed into a rectangular cylindrical shape or other desired shape. The upper edge of the container body 1 is open, and an opening/closing lid 2 is pivotally attached 3 to the upper edge opening so as to be freely openable and closable. There is. 4 is a garbage container; 5 is a receiving frame body formed near the upper edge of the container body 1; the garbage container 4 is supported by the receiving frame body 5 and accommodated in the container body 1 so as to be movable in and out.

Reference numeral 6 denotes an operating lever that is vertically installed in the container body 1 so as to be able to rise and fall freely, with the upper end linked 7 to an appropriate part on the pivot joint 3 side of the opening/closing lid 2. By raising the operating lever 6, the lid 2 is pushed up and opened. It is designed to be covered. Reference numeral 8 denotes a foot lever whose tip is rotatably linked 9 with the lower end of the operating rod 6 and is swingably installed horizontally at the bottom of the container body 1. In the embodiment, the middle part of the foot rod 8 is attached to the container body. It is rotatably attached to a mounting body 11 fixed to the bottom plate 10 of the foot lever 8 by means of a pivot pin 12, and moves in a see-saw shape using the pivot portion as a fulcrum. is projected outside the container body 1 through a window 13 provided at the lower front side of the container body 1. 14 is a petal attached to the above-mentioned protruding end of the foot lever 8; 15 is a petal 14;
This is a regulation stand extending from the bottom plate 10 in correspondence with the above. As a result, when the pedal 14 is stepped on as shown by the phantom line in FIG. and the lid 2 is opened, and
By releasing the pedal 14, the lid 2
is adapted to lower and close the operating rod 6 by its own weight.

Reference numeral 16 denotes an assisting spring having an appropriate spring force and configured to bias the tip side of the foot lever 8 upward. In the embodiment, a coil spring is adopted as the spring 16, and this spring 16 The upper end is fixed 17 to a suitable part on the upper end side of the container body 1, and the lower end is fixed 18 to the tip of a foot lever 8, and the tip of the lever 8 is constantly moved upward by the action of this spring 16. A tensile configuration is shown.

The spring 16 assists in pushing up the lid 2 (opening) when the pedal 14 is depressed.
When the pedal 14 is released, the lid 2
is configured to close by overcoming the action of the spring 16 due to its weight, and therefore, the strength of the spring 16 is appropriately determined depending on the weight of the lid 2, etc.

Note that the means for attaching the assisting spring 16 is not limited to the embodiment, and may be changed to any other configuration.

Reference numeral 19 denotes an insertion hole formed in the receiving frame 5, and the operating rod 6 passes through the insertion hole 19 and connects its upper end to the lid 2.
It has been linked to 7. A brake bushing 20 is made of synthetic resin, and the bushing 20 is fitted and fixed to the operating rod 6 at a location corresponding to the insertion hole 19.

The bush 20 is constructed so that the outer wall surface of the bush 20 comes into sliding contact with the hole edge 19a of the insertion hole 19 when the operating rod 6 is lowered.
The bush 20 of the embodiment has a diameter slightly smaller than that of the insertion hole 19 on the lower end side, and an insertion hole 19 on the upper end side.
It is tapered to have a somewhat larger diameter. As a result, the bush 20 is moved to the operating rod 6.
When the actuating rod 6 is raised, it does not come into sliding contact with the hole edge 19a, and when the operating rod 6 is lowered, it comes into sliding contact with the hole edge 19a, thereby applying the brake (see FIG. 5).
