The present invention relates to a waste bin lid for pressing the waste bin.

In general, various household wastes generated at home or office are purchased under the policy of minimizing household waste, and the standard bags sold by local governments are disposed of at that time. At this time, as a way to minimize the purchase cost for the standard trash bag, the garbage bags having a predetermined internal volume size to contain as much of the garbage as possible to discharge. To this end, while holding the garbage in the garbage bag, hold the top of the garbage bag, put your feet or hands in the garbage bag and step on or push it to minimize the volume of garbage contained in the garbage bag. Ensuring that as much garbage as possible can fit within a given standard bag not only reduces the cost of purchasing the garbage bag but also has the advantage of reducing the number of waste discharges.

However, since most standard garbage bags are made of plastic, there is a problem that the garbage bags are easily torn when holding the garbage bags by hand and pushing the garbage forcibly. In order to solve this problem, the Republic of Korea Utility Model Registration No. 252552 "Paper-based Garbage Bag Mounting Crimping Garbage Bin" puts the garbage can into the garbage bag, puts the garbage, and then uses a ratchet gear formed on the inner circumferential surface of the garbage can. To push it into and fix it.

However, there are dozens of layers in the ratchet gear, which are installed on the inner circumferential surface of the trash can, and dozens of layers. It is difficult, and thus the lid is not completely closed, giving the appearance of a messy look, and also pushes the lid with force by hand, there is an inconvenience that the lid is caught on each layer of the ratchet gear.

The present invention has been made to solve the problems of the conventional press lid.

An object of the present invention is to provide an economical crimping lid that provides convenience for the user and reduces the cost of manufacturing waste bins by not providing a separate additional means such as "latch gear" in the waste bin.

Furthermore, another object of the present invention is to provide a means for the trash can lid to more effectively compress the trash in the trash inside.

To this end, the compression lid was to be able to easily move freely without jamming in the trash, and also to be able to be easily fixed in the desired position.

In order to achieve the above object, the present invention, in the compression lid for pushing the garbage in the trash to the bottom of the trash,

A dustbin lid housing with a handle; A friction drum access groove formed at a side of the lid housing at a position opposite to each other with respect to the inner center of the lid housing; The drum pad of the resilient material that the lid housing is drawn in through the friction drum access groove when the lid housing, when moving, and pulled out through the friction drum access groove when fixed; A drum pad pusher attached to the friction drum pad to transmit a force; According to the action of the elastic spring to transfer the power to the drum pad push rod, one end is connected to the drive spring, the other end is connected to the drum pad push rod, the force to pull inward and push towards the drum pad push rod that is outside A spring connector having a rotational central axis such that the rotational axes are opposite to each other;

A driving spring fixedly connected to one end of the spring connecting member to provide a pulling force to the spring connecting member and to suppress an excessively pulling force; A friction drum drive unit connected to the driving spring and the driving line, exposed to the outside of the lid housing, positioned under the handle, and having a circular groove formed in the center thereof, and having a support inserted into the groove, and rotatable with respect to the support. When the drum drive unit is pulled up, the driving spring is pulled out, and by this action, the friction drum pad is drawn out of the lid housing. When the friction drum drive unit is released, the friction drum pad is restored by the restoring action of a restoring spring. A friction drum drive for introducing into the lid housing; And a friction drum drive part stopper which keeps the friction drum pad drawn out of the lid housing by pulling up and rotating the friction drum drive part.

In addition, in the position opposite to each other with respect to the center of the lid housing, so that the compression lid can be fixed more easily and balanced inside the trash can, the balance protrusion is regulated by the spring elasticity on the side of the lid housing It may be further provided.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, when it is determined that the subject matter of the present invention may be unnecessarily obscured by those skilled in the art such as related well-known functions or known configurations, the detailed description thereof will be omitted.

1 is a view showing a state diagram used to position the compression lid on or in the trash (1). The present invention relates to a compression lid used in the trash can (1), the trash can (1) of the trash can (1) itself except that the size can be made or purchased in advance to pair with the compression lid Since the present invention is not completed by the technical addition or the scope of the present invention is not limited, the description of the trash can itself will be omitted below. However, the outer configuration of the compression lid is largely shown as an embodiment consisting of the lid housing 70, the handle 71, the friction drum drive portion 72, the drum pad 73, the balance protrusion 74.

2 shows the position and configuration of the friction drum drive unit 72 and the working principle in more detail. The friction drum drive 72 is located below the handle 71 but is exposed to the outside of the lid housing. A circular groove is formed in the center of the friction drum driving unit 72, and the support 77 is penetrated through the circular groove, and both ends thereof are fixed to the handle 71 and the lid housing upper frame 69. When the user grabs and pulls up the friction drum drive unit 72 using a finger, the drum pad of the compression lid is protruded by a friction spring drive unit 72 and a driving spring connected through the drive line 79 'in the housing. And both of the friction drum drive stopper 75 to fix the position of the friction drum drive unit 72 in order to maintain the protrusion state of the drum pad.

3 shows a schematic configuration of the friction drum drive unit 72 and the friction drum 73 connected to each other inside the lid housing. The inner circumferential surface of the trash can 1 and the compression lid 70 in the trash can 1 is not completely in contact with each other, there is a slight gap. Because of this gap, the pressing lid moves freely inside the trash can. In order to fix the pressing lid, it is necessary to completely remove the gap or to fill the gap at a specific position. However, the removal of the gap completely requires a very large external force, so in the embodiment of the present invention, the gap is completely filled only in the place where the friction drum housing 78 is located. To this end, the friction drum 73 is composed of a friction drum housing 78, a driving spring 79, the drum pad 82 in the lid housing. The drum pad 82 is made of a resilient material such as silicone or rubber, and is connected to a drum pad pusher 81 which transmits an acting force for entering and exiting the drum pad 82 in the friction drum housing 78. When the driving spring 79 is pulled, the rotational force by the rotation of the spring connecting rod 80 is transmitted to the drum pad pusher 81, whereby the drum pad 82 protrudes through the access groove formed in the lid housing side portion 76. As a result, it is in close contact with the inner surface of the trash can (1). In the case where two drum pads 82 are mounted, the drum pads 82 are located at the positions facing each other with respect to the center of the lid housing, and thus the access grooves are also opposed to each other with respect to the inner center of the lid housing. Is formed on the side portion 76 of the lid housing.

4 illustrates this action in more detail. The driving spring 79 is connected to one end of the spring connecting member 80, the drum end pad 81 is connected to the other end of the spring connecting member 80 by the connecting means 83, in this case ① When the force in the direction of the arrow is generated, a force is generated to rotate about the center of rotation in the center of the spring connection. By this rotational force, the drum pad pusher 81 transmits a force in the same direction as arrow ②. As a result, the drum pad 82 to which the drum pad pusher 81 is attached is pushed back, thereby being in close contact with the inner circumferential surface of the trash can. On the contrary, when the user places the friction drum driving unit 72 in the original position, the rotational force in the opposite direction is generated by the elastic restoring force of the restoring means 88 composed of a restoring spring, and the drum pad 82 returns to the original position. As a result, the gap between the compression lid and the trash can opens, allowing the lid to move freely within the trash can.

5 is a cross-sectional view for explaining in more detail the operating principle of the friction drum drive unit 72 for driving a force to the action of the friction drum 73. The support 77 penetrates the lid housing upper frame 69 and the friction drum drive 72 so that both ends are fixed to the lower portion of the handle 71 and the lid housing bottom 68. The center of the friction drum drive unit 72 is provided with a circular groove through which the support 77 penetrates, and the friction drum drive unit 72 can be rotated through the circular groove. Then, the fixed compression spring 84 is connected to a predetermined position of the friction drum drive unit 72 so that the friction drum drive unit 72 descends to the lid housing upper frame 69 and the other end is attached to the handle 71. . A driving line 79 'connected to the driving spring 79 is connected to a specific portion of the lower portion of the friction drum driving unit 72 (represented as a connecting cylinder portion between the friction drum driving unit and the driving line in FIG. 5) (the driving line in FIG. 5). When the friction drum driving unit is lifted in the direction of arrow 3, the driving line 79 'to which the driving spring 79 is connected is pulled.

On the other hand, in order to maintain the state in which the drive line 79 'and the drive spring 79 are pulled intact, the friction drum drive unit is rotated in the direction of image table # 4, and then it is located on the friction drum drive unit stopper 75. 6 is provided for easier understanding of this. That is, one end of the friction drum drive portion 72 is in the "A" position of the friction drum drive portion stopper 75 before rotation in the direction of arrow ④, but after pulling and rotating, the end is placed in the "B" position. The force to pull up the drive spring 79 is maintained. The same applies to the other side of the friction drum drive unit 72.

In another embodiment, a means is provided to keep the compression lid secured and more balanced. At a position opposite to each other with respect to the center of the lid housing 70, the side surface 76 of the lid housing is further provided with a balance protrusion 74 is regulated by the spring elasticity. For example, if the friction pad is configured to enter and exit the east and west sides of the side portion 76 of the lid housing, the balance protrusion 74 is configured on the north and south sides. This is illustrated in FIG. 7. Forming a groove for entering and exiting the balance protrusion 74 at a predetermined position of the side portion 76 of the lid housing, through which the balance protrusion 74 is inserted and mounted, the end of the balance protrusion 74 is elastic It is connected to the strong balance projection spring 85, the balance projection spring 85 is connected to the balance projection support 87. A predetermined balancing protrusion stopper 86 is provided to prevent the balancing protrusion 74 from completely entering the housing. When the compression lid is pushed into the waste bin, the balance protrusion 74 enters the compression lid by contact with the inner circumferential surface of the waste bin. However, since the strong repulsive force is applied to the inner circumferential surface of the waste bin by the balance protrusion spring 85, it helps to fix the compression lid position in the waste bin.

When the user puts garbage in the trash can and the garbage needs to be compressed to some extent, the user can push the compression lid into the trash. At this time, if the friction drum drive unit 72 is pulled up and fixed by the friction drum drive unit stopper 75, it may be released. If the compression lid is to be stopped at the position after the garbage is compressed, the friction drum driver 72 may be pulled up again, rotated, and then fixed by the friction drum driver stopper 75.

Through the configuration of the present invention as described above, there is a convenient effect that can simply compress the waste by the compression lid of the present invention even without a separate additional means such as "latch gear" in the waste bin.

In addition, since the trash can can be used as a conventional monotonous cylindrical trash can as it is, there is no need to produce a specially designed trash can inside, there is a cost saving effect that can be separately produced or purchased only compression lid.

In addition, the unique effects produced by the unique structure of the present invention are not limited to the matters described in the above-described examples and claims of the present invention, but also to a broader range due to the effects that can occur within the range easily conceivable therefrom. Affirm that it will be included.
