Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a bottle opener, and particularly to a bottle opener used to remove a crown fitted to the mouth of a bottle and open the bottle.

<Conventional technology> The bottle openers commonly used in the past (referring to bottle openers exclusively for crowns, excluding Kirk pullers) are flat plate-shaped with an opening at the tip, and the handle part is lifted from below to above against the bottle. It is of the type that removes the crown by action.

In comparison, there is a crown remover that is placed on the crown and removes the crown by pressing downward from the top of the bottle, for example,
As seen in Publication No. 3235, it has already become publicly known.

<Problems to be Solved by the Invention> The present invention relates to a crown extractor of the latter type that can remove and open a bottle by simply pressing the bottle from above to below. The crown extractor described in the above publication has an extremely large number of parts, has a complicated mechanical structure, and requires a great deal of time and effort to assemble the parts, making it an expensive product and lacking in marketability. It has not yet been commercialized due to the lack of

The present invention eliminates these drawbacks, reduces the number of parts as much as possible, simplifies the mechanical structure,
Our aim was to develop a crown remover that minimized the time and labor required for assembly and could be offered to the market at a low cost.As a result of various research, we were finally able to achieve this aim. This is what I propose here.

<Means for Solving the Problems> The structure of the present invention that has made it possible to achieve this object will be explained using drawings shown as examples. An outer cylinder 1 which is a crown remover that is brought into contact with the bottle and opened by pressing from above, and has a lever engagement step 1a protruding from the inner surface and an opening 1c for inserting the bottle head from the bottom.
It is inserted into the outer cylinder 1 so as to be vertically movable, has a crown insertion space 8 and a crown contact part 2 at the lower part, and is directed inward to the side opposite to the side where the multi-crown contact part 2b is formed. A vertically movable frame 2 has an inwardly protruding inclined portion 2a projecting from above, and is pivotably supported on the vertically movable frame 2 by a pivot pin 4, and one end portion 3a is connected to a lever of the outer cylinder 1. One swinging lever 3 is always engaged on the joint step part 1, and the other end of the swinging lever 3 is pivoted in a hanging position by a pin 6, and has a crown on the lower end. one drooping lever 5 having a crown engaging piece 5b that engages with the outer circumferential portion of the lower edge of the lever and an inwardly recessed inclined portion 5a on the back side; A single coil spring 7 is stretched between the vicinity of one end 3a of the swinging lever 3 and the top 2c of the vertically moving frame 2, Lever 5
The inwardly recessed inclined portion 5a abuts the inwardly protruding inclined portion 2a of the vertically movable frame 2, and the crown engaging piece 5b
It has a structure in which it moves inward.

<Function> To remove the crown using the crown remover according to the present invention, hold the outer cylinder 1 and insert the bottle a into the opening 1c of the lever.
Insert the crown b and lower the outer cylinder 1 downward. In this way, a part of the upper edge of the crown b comes into contact with the crown abutting portion 2b, and this abutting action prevents the vertically movable frame 2 housed inside the outer cylinder 1 from descending. As the outer cylinder 1 is further lowered, the lever engaging step part 1a in the outer cylinder 1 presses down the engaging part of the one end part 3a of the swinging lever 3, and the lever 3 is rotated around the pivot pin 4 as a pivot. Shift to the reverse tilted position as shown in Figure 2. As the posture of the lever 3 changes, the hanging lever 5 rises, and during this rising action, the inwardly recessed inclined portion 5a of the lever 5 comes into contact with the inwardly protruding inclined portion 2a of the vertically movable frame 2. At the same time, the lower crown engaging piece 5b engages with the outer circumference of the lower edge of the crown b, and the cap is opened by continuing the upward movement.

After opening, the outer cylinder 1 can be lifted upward.

Although the crown remover of the present invention has a simple configuration with only one coil spring 7,
The spring 7 always urges the one end 3a of the swing lever 3 in the upward direction, and therefore the hanging lever 5 pivoted to the other end of the lever 3 is only constantly moved in the downward direction. At the same time, the one end 3a
Since the outer cylinder 1 is always tightly engaged with the engagement step 1a of the outer cylinder 1, the outer cylinder 1 is also constantly urged in the upward direction by the elasticity of the one spring 7 through the step 1a. . In other words, one spring 7 acts in a direction to return both the swing lever 3 and the outer cylinder 1 to their original positions. In addition, when not in use, the inwardly protruding inclined portion 5a of the hanging lever 5 is in a retracted position below the inwardly recessed inclined portion 2a of the inner wall surface of the vertically movable frame 2, and when opening the bottle, the inwardly protruding inclined portion 5a of the hanging lever 5 is in a retracted position from this position. Since the structure is such that the crown engaging piece 5b at the bottom of the lever 5 is displaced inwardly when the lever 5 comes off, it allows the engaging piece 5b to retreat outward when it goes under the crown when it is set on the top of the bottle. The structure does not require any springs.

<Examples> Examples of the present invention will be described below based on the drawings.

The outer cylinder 1 is molded from a synthetic resin material, and has an engaging stepped part 1.
A is a cylindrical body with a bottom that is integrally formed on the inner surface of the vertically movable frame 2, and then a flange 1b for restricting the downward movement of the vertically movable frame 2 is fitted and fixed to the inner periphery of the opening with adhesive. . The vertically movable frame 2 is made of a sheet metal material and is formed into a U-shape in plan view, and is housed inside the outer cylinder 1 with the engaging stepped portion 1a being held between the opening side portions of both side plates 2d and 2b. be. In the lower halves of the side plates 2d and 2b, a portion that forms a gap 8 that allows the crown b to fit therein and is large enough for the removal action of the crown b is cut out, and a part of the side edge side portions are cut out in the width direction. The crown abutting portion 2b is formed by bending the crown abutting portion 2b. The swinging lever 3 is a rod-like body with a U-shaped cross section, and one end 3a thereof engages with the engagement step 1a, and the pin 4 is placed in an inclined position with the engagement side in an upward position.
The upper end portion of the hanging lever 5 is pivotally supported by a pin 6 at the other end portion. The hanging lever 5 has a crown engaging piece 5b connected to the lower end thereof in an upwardly inclined shape that abuts and engages with the outer circumference of the lower edge of the crown b, and has an inwardly recessed inclined part on the back side thereof. 5a is formed.
The coil spring 7 has a locking protrusion 3b formed protruding from the back surface of the swing lever 3 near the one end 3a side.
and a locking part formed by bending the top part 2c of the vertically movable frame 2.

When the crown remover with the above structure is used, when the hanging lever 5 moves upward with respect to the vertically movable frame 2, as shown in the enlarged action diagram in FIG. The recessed inclined portion 5a contacts and is guided by the inwardly protruding inclined portion 2a of the vertically movable frame 2,
The crown engaging piece 5b at the lower end is moved to the crown b side, and the crown b is removed and opened as described above.

In the above embodiment, since the swinging lever 3 having a downward U-shaped cross section is placed inside the U-shaped recess of the U-shaped vertical movement frame 2, all movable parts can be compactly mounted on the outer cylinder 1. The crown extractor as a whole has a simple structure and is convenient for manufacturing and handling.

Although typical embodiments of the present invention have been described above, the present invention is not necessarily limited to the structure as shown in this embodiment. It can be implemented with appropriate modification within the scope of achieving the following requirements.

<Effects of the Invention> As described in detail above, in the present invention, the crown removal mechanism part installed inside the outer cylinder has a vertical movement frame,
All that is required is one swinging lever that is pivotally supported by a pin, one hanging lever that is pivotally supported by a pin, and one coil spring. Therefore, the number of parts is extremely minimized, and assembly is extremely simple and quick, making it possible to offer the product value to the market at a low price as a crown remover to replace the conventional lever type. It's expensive.
