Description

Cup opening and closing lid {Cup having an automatically openable lid}

The present invention relates to a cup having a lid that automatically opens and closes, and more particularly, to a cup in which the lid is automatically opened and closed by the weight of the cup.

In general, a cup does not have a lid so that other foreign matters may be introduced, or a hot drink such as coffee may be quickly eaten and may not feel its original taste for a long time. Therefore, to prevent this, a lid replacement cover may be placed on the top of the cup or a cup with a lid may be used. However, this is inconvenient to open the lid when a person drinks directly, and to close the lid when not drinking. In addition, there was a problem that the lid is easily lost.

The present invention was devised to solve the above problems, by installing a lid that opens and closes by turning on the top of the cup to automatically open the lid to open the cup, when the cup is put down to provide an automatic lid opening and closing cup that is closed The purpose is.

Automatic lid opening and closing cup according to the present invention for achieving the above object, the cup body; A working rod which protrudes vertically through a surface of which the bottom surface of the cup body extends outwardly and is formed with a rack; Return means installed on the same axis as the operating rod; A pinion assembled to mate with the rack; A first bevel gear assembled spaced apart on the same axis as the pinion; A second bevel gear assembled to engage with the first bevel gear; And a cup lid installed at an upper end of the shaft of the second bevel gear.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in more detail.

Referring to FIG. 1, the automatic lid opening and closing cup consists of a cup main body 1, a lid turning device 10 installed on the side of the cup main body 1, and a cup lid 3 coupled to the turning device 10.

Lid turning device 10 is a working rod 11, the operating rod 11, the bottom surface of the cup body 1 is projected vertically penetrating through the surface (1a) extending outwards and the rack 11a is formed. Return means installed on the same axis as the pinion pinion 12 assembled to mate with the rack 11a, the first bevel gear 14 and the first bevel spaced apart on the same shaft 13 as the pinion 12 And a second bevel gear 15 and a bevel gear shaft 16 assembled to mate with the gear 14.

The pressure plate 11b is attached to the lower end of the operating rod 11, and the rack 11a is formed in the middle part. The rack 11a is formed by a length such that the cup lid 3 is pivoted to deviate from the upper end of the cup body 1 by the combined movement with the pinion 12 to be engaged.

On the upper end of the operating rod 11 is provided a compression spring 17 as a return means. The compression spring 17 should have an elasticity enough to open the cup lid 3 by pushing the operating rod 11 downward when the cup is lifted.

The return means may attach the balance to the actuation rod 11 instead of the compression spring 17 to raise the cup so that the actuation rod 11 is lowered by gravity to allow the cup lid 3 to pivot.

It is obvious that the operating rod 11 should be firmly supported at both ends so as to perform accurate vertical movement.

The pinion 12 which converts the up-and-down movement of the operating rod 11 into rotational motion is engaged with the rack part 11a of the operating rod. The pinion shaft 13 is supported at both ends, and the first bevel gear 14 is assembled at one end. The first bevel gear 14 is fitted with a second bevel gear 15 assembled to the bevel gear shaft 16 perpendicular to the pinion shaft 13 and perpendicular to the bottom surface 1a of the cup body 1. The vertical movement of the operating rod 11 is transmitted to the rotational movement of the bevel gear shaft (16). The bevel gear shaft 16 is also supported at both ends.

At the upper end of the bevel gear shaft 16, a cup lid 3 having a size capable of covering the opening 1b of the cup body is attached. The position at which the upper end of the bevel gear shaft 16 is coupled to the cup lid 3 may be opened when the cup lid 3 is rotated by the rotation of the bevel gear shaft 16. It is desirable to select a location.

Referring to the operation of the automatic lid opening and closing cup having the configuration as described above are as follows.

When the cup body 1 is placed on the floor of a table or the like, a force acts on the pressure plate 11b by the weight of the cup. The operating rod 11 is raised by this force. When the operating rod 11 is raised, the pinion 12 is rotated counterclockwise by the rack 11a formed in the operating rod 11. When the pinion 12 rotates, the first bevel gear 14 on the pinion shaft 13 also rotates counterclockwise. When the first bevel gear 14 rotates, the second bevel gear 15 also rotates counterclockwise. When the second bevel gear 15 rotates, the bevel gear shaft 16 on which the second bevel gear 15 is assembled also rotates, so that the cup lid 3 attached to the bevel gear shaft 16 counterclockwise. It turns and covers the opening part 1b of a cup main body (refer FIG. 2A).

On the contrary, when the cup is lifted, the operating rod 11 receives downward force by the elasticity of the compression spring 17 as the return means. When the operating rod 11 is lowered, the pinion 12 is rotated clockwise by the rack 11a formed on the operating rod 11. When the pinion 12 rotates, the first bevel gear 14 on the pinion shaft 13 also rotates clockwise. When the first bevel gear 14 rotates, the second bevel gear 15 also rotates clockwise. When the second bevel gear 15 rotates, the bevel gear shaft 16 on which the second bevel gear 15 is assembled also rotates so that the cup lid 3 attached to the bevel gear shaft 16 pivots clockwise. This opens the opening 1b of the cup body (see FIG. 2B). In other words, the action is reversed when the cup is put down.

Another embodiment of the present invention is to incline the top of the cup body as shown in FIG. The incline raises the area where people wear the cup and lowers the turn point.

The lid turning device 10 and the cup lid 3 are the same as in the above-described embodiment, and only fit well on the inclined surface so as to operate smoothly.

Inclined to the top in this way, when drinking a drink can prevent the cup lid from touching the forehead or hair.

As described above, according to the present invention, the lid is automatically opened when the cup is lifted, and the lid is automatically closed when the cup is put down so that people do not need to open or close the lid by hand, and the lid is attached to the cup. There is no loss of life.

In addition, when the upper end of the cup body is inclined, it is possible to prevent the lid from interfering with the forehead or hair when drinking the beverage.

In the above described and preferred embodiments of the present invention, but also described, the present invention is not limited to the specific embodiments described above, the technology to which the subject innovation belongs without departing from the gist of the subject innovation claimed in the claims below Those skilled in the art will be able to implement various modifications.
