Description

Hinge of container lid

The present invention relates to a hinge portion that rotates the lid of a container in which the lid is opened and closed by a pivoting structure, and in particular, as the friction phenomenon occurs in the hinge portion during rotation of the lid, the opening and closing speed of the lid is appropriately slowed. The present invention relates to a technology capable of preventing a strong collision between the lid and the container.

In general, a container that can easily contain contents, such as a trash can or a food waste container, and at the same time need to block the contents from the outside, uses a cover that is opened and closed by a rotation method.

Rotating structure of such a cover is made through the hinge portion (H) as shown in Figure 1, the existing hinge portion (H) is provided with a rotating shaft 200 formed on the cover 2000 in the container 1000 It is made of a structure inserted into the housing 100.

In addition, the cover 2000 is configured to rotate about the rotation shaft 200 to open and close the inlet of the container 1000.

By the way, the general hinge portion (H) is simply a structure for the rotation operation of the cover only when the cover is in the process of operating the cover when the cover is rotated by its own weight to collide with the top of the container, at this time the cover or the container is damaged by the impact It happens frequently.

In addition, when the above case occurs in the food container, the food waste that is buried on the cover or the container entrance is splashed in all directions at the moment when the cover hits the top of the container.

Recently, in order to solve this problem, when the cover 2000 and the container 1000 are connected with the cylinder S to close the cover 2000, the cover 2000 is slowly closed due to the pressure in the cylinder S. Techniques to make it have been proposed.

However, the prior art has a disadvantage in that the additional cost of the entire product is inevitably increased due to the additional installation of the cylinder S, and the cylinder S is exposed to the outside.

The present invention is proposed to solve the problems of the prior art as described above,

Basically, the rotational speed of the cover can be properly adjusted in a certain section during the opening and closing process of the cover, so the hinge of the container cover can be provided to minimize the impact when the cover and the container collide.

In addition, it is possible to adjust the rotational speed of the cover with a simple structure compared to the conventional, and to provide a hinge portion of the container cover that can prevent the unit cost rise due to the improvement of the structure.

In addition, by improving only the hinge structure of the hinge to adjust the rotational speed of the cover to provide a hinge portion of the container cover that can reduce the risk of damage to the rotational speed adjustment structure is not exposed to the outside.

The present invention for achieving the above object,

The container and the cover is provided on one side and one side of the housing is formed with an insertion hole and the other is provided on the other side consisting of a rotating shaft which is inserted into the insertion hole.

And one or more of the inner circumferential surface of the insertion hole and the outer circumferential surface of the rotating shaft of the basic configuration is characterized in that the friction member is formed in contact with the friction member in the other.

And the friction member is characterized in that it is made of a projection projecting from any one of the inner peripheral surface of the insertion hole and the outer peripheral surface of the rotation shaft.

In particular, when the friction member is provided in the rotational shaft, the friction section is characterized in that it is formed in a form formed closer to the distance from the center point than the non-contact section.

In addition, it characterized in that the uneven portion is formed on the contact surface with the friction member of the friction section.

In addition, the friction member is installed through a separate elastic means is characterized in that the elastic means is compressed in contact with the friction section and returned to its original position when not in contact.

The present invention consisting of the above characteristic configuration,

Basically, as the friction between the friction member and the friction section is made during the rotation of the cover, the rotational speed of the cover is appropriately reduced by the frictional force, and the impact is minimized when the cover covers the container, thereby preventing damage to the cover or the container. There is an advantage.

In addition, since the friction member and the friction section are realized only through the insertion hole shape deformation of the rotation shaft and the housing, unlike the conventional technology in which a structure such as an existing cylinder is added, there is an advantage in that a unit cost increase of the product is hardly generated.

In addition, since the friction member and the friction section are not exposed to the outside, the probability of failure of the friction structure is lower than that of the conventional one.

Hereinafter, with reference to the configuration illustrated in the drawings to describe various embodiments of the specific configuration and its operation of the present invention.

For reference, the shape of the lid and the container to which the present invention is applied may be variously modified, and this is not related to the scope of the present invention, and thus the detailed description of the lid and the container will be omitted.

Hinge portion (H) of the container cover of the present invention is composed of a housing 100 and a rotating shaft 200, as shown in [FIG. 2] and [FIG. 3].

First, the housing 100 is a portion forming the pivot structure, that is, the hinge portion (H) of the cover 2000 through a combination with the rotating shaft 200 to be described later, has a cylindrical shape and at the center of one side of the groove-shaped insertion opening ( 110 is formed, the container 1000 is provided in a form protruding outward from both sides of the inlet.

At this time, on the inner circumferential surface of the insertion hole 110 is formed a friction section 112 for adjusting the rotational speed of the cover 2000, this friction section 112 is not formed through the addition of a special component, but simply the insertion hole 110 It is realized only by the shape deformation of.

First, the insertion hole 110 is basically a circular shape, that is, the distance A between the central point and the inner circumferential surface is always constant. At this time, some sections of the inner circumferential surface have different curvatures so that the distance (B) is closer to the center point than other sections. Thus, the close section becomes the friction section 112 and the remaining section becomes the non-contact section 114.

The formation point of the friction section 112 may be in contact with the friction member 210 of the rotating shaft 200 which will be described later immediately before the cover 2000 is covered with the container 1000 in the process of rotating toward the container 1000. To be set.

The pivot shaft 200 serves as a central axis during the rotation of the lid 2000. The pivot shaft 200 has a simple cylindrical shape and is located at both ends of the lid 2000.

When the diameter of the rotation shaft 200 is smaller than the inner diameter of the housing insertion hole 110 and fitted to the insertion hole 110, the friction member 210 to be described later is located between the rotation shaft 200 and the insertion hole 110. Allow gap C to be formed.

A friction member 210 is formed at one side of the rotation shaft 200, and the friction member 210 is configured to friction between the rotation shaft 200 and the housing 100 during the rotation of the cover 2000. In this case, the rotating shaft 200 is formed in the form of a protrusion protruding from the outer peripheral surface.

As shown in the drawing, the friction member 210 may have one protrusion formed throughout the longitudinal direction of the rotation shaft 200 or spaced apart at intervals along the longitudinal direction.

And the height of the protrusion of the friction member 210 is deformed according to the shape of the friction section 112 of the housing 100,

Specifically, the distance from the center point of the rotating shaft 200 to the end of the friction member 210,

As the distance between the non-contact section 114 is set from the center point of the housing 100 or less, friction does not occur when the friction member 210 passes through the non-contact section 114 when the cover 200 is rotated. .

On the other hand, by setting the distance from the center point of the housing 100 to the friction section 112 or more so that the friction between the friction member 210 in the process of passing through the friction section 112 is mutually made.

Since the friction member 210 is made of a material having excellent abrasion resistance and high elasticity, such as urethane rubber, the friction member 210 is not easily worn even if the friction with the friction section 112 is repeated. Make shape restoration easy.

In the state where the friction member 210 is located in the non-contact section 114 of the housing 100, the surface 220 facing the friction section 112 of the rotational shaft 200 has a curvature compared to other surfaces. By making the friction section 112 parallel to the friction section 112, a sufficient gap D is formed between the friction section 112 and the rotation shaft 200.

The reason why the gap D is to be formed between the rotation shaft 200 and the friction section 112 is that between the friction section 112 and the rotation shaft 200 when the entire rotation shaft 200 is in a circular state. Since the gap is hardly formed, in this case, the friction member 210 may not pass through the friction section 112, and thus the cover may not rotate.

Thus, the cover 2000 and the container 1000 provided with the rotation shaft 200 and the housing 100 are coupled by inserting the rotation shaft 200 into the insertion hole 110 of the housing 100.

For reference, in the above description and drawings, the rotation shaft 200 is provided on the cover 2000 and the housing 100 is provided on the container 1000, and the rotation shaft 200 is rotated when the cover 2000 is rotated. It has been described as being limited to a structure that rotates within), but this can be modified to any other structure.

That is, the rotating shaft 200 is provided in the container 1000 and the housing 100 is provided in the cover 2000 so that the housing 100 rotates around the rotating shaft 200 when the cover 2000 is rotated. It can also be done.

In addition, the friction member 210 may be formed in the insertion hole 110 and the shape of the rotation shaft 200 may be modified so that the friction section 112 is formed on the rotation shaft 200.

Hereinafter will be described the operation of the present invention and the effects generated in the operation process by the above configuration.

First, in the state in which the cover 2000 is opened as shown in FIGS. 2 and 3, the friction member 210 of the rotation shaft 200 is positioned in the non-contact section 114 of the housing 100.

When the cover 2000 is flipped toward the container 1000 in this state, the cover 2000 and the rotation shaft 200 are rotated around the connection point with the housing 100.

At this time, since the friction member 210 is not in contact with each other in the process of passing through the non-contact section 114, the cover 2000 is quickly rotated by its own weight without any interference.

Then, the moment the friction member 210 passes the friction section 112, the contact between the friction section 112 and the friction member 210 is made, in this process by moving the surface of the friction member 210 in a pressed state that much A large friction force is generated and the rotation speed of the cover 2000 is slowed down by this friction force.

Therefore, the rotation speed of the lid 2000 is slowed down just before the lid 2000 completely covers the container 1000, so that impact is hardly generated even if the lid 2000 hits each other at the moment when the lid 2000 completely covers the container 1000. .

As described above, the present invention provides a friction structure between the rotation shaft 200 constituting the hinge portion H and the housing 100 to adjust the rotation speed of the lid 2000 to an appropriate level, thereby colliding with the container during the opening and closing process. Due to the impact due to it can be minimized, the biggest feature is that in order to prevent the damage to the cover (2000) or the container (1000).

In addition, the rotational speed of the cover 2000 is realized by simply deforming the shape of the insertion hole 110 and the inner circumferential surface of the rotational shaft 200 without any additional configuration. It is another feature that it is not only simple, but also no increase in unit cost of the product.

The present invention may be practiced in various forms,

5 and 6 are views showing a second embodiment of the present invention, the rotating shaft 200 and the housing through the friction member 210 and the friction section 112 during the rotation of the lid 2000. Basic structure of the friction between the 100 is the same, but the friction member 210 is characterized in that it is installed through a separate elastic means 400 without integrally molded on the rotating shaft (200).

At this time, the elastic means 400 is used is made of a torsion coil spring form and is coupled through a coupling protrusion 230 formed on the front end surface of the rotational shaft (200).

At this time, the friction member 210 is positioned at one side of the support piece 410 of the elastic means 400 so as to protrude from the pivot shaft 200.

When the friction member 210 is in contact with the friction section 112 by rotating the lid 2000 as shown in FIG. 6 in the state in which the friction member 210 is installed in this form, the support piece 410 of the elastic means 400 is provided. ), The friction member 210 is also pushed to one side.

However, at the same time, since the friction member 210 is maintained in close contact with the friction section 112 by the elastic force of the folded support piece 410, sufficient friction force is formed in the process of passing through the friction section 112.

In addition, in this embodiment, the friction between the friction member 210 and the friction section 112 is made by the elastic force of the elastic means 400, unlike the previous embodiment, the shape deformation of the friction member 210 is made in the contact process You won't lose.

Therefore, since the friction member 210 can be made of a material such as metal having a higher wear resistance than rubber, there is an advantage that the life of the product can be extended.

In addition, Figure 7 is a view showing a third embodiment of the present invention, the structure using the contact between the friction member 210 and the friction section 112 is the same as the previous two embodiments, but the friction section 112 By forming the concave-convex portion 112a on), the friction effect with the friction member 210 is further enhanced.

Although not shown in the drawing, the frictional force may be further increased when the concave-convex portion is formed on the friction member 210.

Each of the features of the present invention described above may be variously modified and combined by those skilled in the art, but in the structure in which the cover is opened and closed on the container through the hinge portion made of a coupling between the housing and the pivot shaft,

In the process of opening and closing the cover, the rotational speed of the cover is slowed down by the friction between the rotating shaft constituting the hinge part and the friction member and the friction section formed in the housing, thereby preventing damage caused by the collision between the cover and the container. If relevant, it should be determined that it belongs to the protection scope of the present invention.
