Description

[Detailed Description of the Invention] The present invention relates to a necked kettle in which a spout is provided with a spout that can be opened and closed, and a flute is built into the spout.

A kettle with a neck is a type of kettle that, when the water boils, lets the steam pass through a whistle built into the spout that seals the spout, causing a whistle to sound to let you know that the water has boiled.

In the case of such a keratle, if you install a mechanism that not only allows the palate to open and close, but also holds the palate in an open position, you can open the lid once before pouring hot water, and from then on, when pouring hot water, There is no need to support the palate with fingers to maintain the open state.

If the whistle operation is not required when boiling the shaft groove, the palate can be opened to prevent the whistle from operating.

For this reason, various mechanisms for maintaining the lid open state have already been provided (for example, Japanese Utility Model Application No. 56-62721).

However, with the conventional mechanism, when the lid is opened by pushing the finger rest with your finger from the closed state, the roof of your mouth suddenly opens fully, and there is a risk that the high-temperature water that has adhered to the neck area will splash onto your fingers, causing your fingers to burn. be.

Furthermore, in the conventional mechanism, the lid can only be in two states: fully open and fully open, so it is necessary to set the lid in the fully open state when the whistle is not required to operate.

For this reason, the diameter of the spout is relatively larger than that of regular kettles, which means that there is not only a risk of boiling water splashing out, but also that it is easy for dirt to get in from the outside. .

In view of these circumstances, an object of the present invention is to provide a mechanism capable of holding the palate in an open state and also in a half-open state, thereby solving the various problems described above.

The invention will now be described in conjunction with the drawings.

FIG. 1 is a longitudinal sectional side view of the necked kettle according to the present invention.

The keratle main body 1 is integral with the bottom part 2, the upper hole 3 is closed by fitting the lid 4, and the handle 5 is integrated with the main body 1 by a leading rivet 6.

Further, a cylindrical spout 8 projecting obliquely upward is integrally attached to the hole 7 of the main body 1, and a palate mounting bracket 9 is attached to the clay wall portion 8a of the spout 8.

The metal fitting 9 has three tongues 9a, as can be seen in more detail in FIG. The fitting 9 is fixed to the spout 8 by being bent inside.

The metal fitting 9 has a guide edge 9b on its outer edge that is substantially parallel to the axis A of the spout 8, and has a bent portion 9C bent toward the spout 8 at the upper end of the guide edge, allowing the palate 11 to rotate. It has a hole 9d through which a pin 10 for supporting is passed.

Palate 1 rotatably supported via pin 10 in hole 9d
1 is a lid part 11a that closes the spout upper end 8b and a finger hook part 11
b, a whistle 12 is built into the lid part 11a, and the whistle 1
2 is a disk portion 1 with a small circular hole 12a for steam passage in the center.
2b and 12b', and a circular downward convex portion 12C is provided on the disk portion 12b' forming the bottom portion of the lid portion 11a.

A rectangular recess 1 is provided on the lower surface of the palate 11 in a portion facing the metal fitting 9.
1C, and a U-shaped leaf spring 13 is fitted into the recess 11C so as to open toward the spout 8 side and form a U-shape when viewed from the side.

As can be seen in more detail in FIG. 3, which is a perspective view, the leaf spring 13 has rectangular notches 13 at both corners of the tip of the rectangular lower piece 13H.
For example, it is made of an elastic material such as steel with a thickness of about 0.2 mm, and in the released state, the angle B is almost a right angle and the angle C is an obtuse angle.

The leaf spring 13 is fitted into the recess 11C so that the lower piece 13a protrudes downward from the lower surface of the roof of the mouth 11, and the lower piece 13a
is in elastic contact with the tip 9e of the bent portion 9C of the metal fitting 9, and a convex portion 13C formed by the notch 13b enters the side wall surface of the metal fitting 9.

FIG. 1 shows the necked kettle according to the present invention in a state in which the palate 11 is closed, and the palate 11 is opened by pushing down the finger hook 11b with a finger.

When the lid 11 starts to be opened from the state shown in FIG.
The point of contact with the tip 9e moves toward the tip of the lower piece 13a.

When the lid 11 continues to be opened, it first stops when the lower piece 13a and the bent portion 9C come into surface contact, that is, in the half-open state (indicated by the two-dot chain line).

When the lid 11 is further opened, a bent portion 9 is formed on the lower piece 13a.
C and the corner 9f formed by the guide edge 9b abut, and the lower piece 13a is compressed by the corner 9f, and at the same time, the contact point of the lower piece 13a with respect to the corner 9f moves toward the tip of the lower piece 13a.

When the lid 11 is further opened, the lower piece 13a and the guide edge 9b
It stops at the point when it comes into surface contact, that is, when it is fully open (the state indicated by the two-dot chain line E).

When closing the palate 11 from the fully opened state, the above process is reversed to return to the state shown in FIG. 1.

As explained above, according to the present invention, the kerator body 1
A palate 11 with a flute 12 is rotatably attached via a horizontal pin 10 to a palate mounting bracket 9 attached to a clay wall portion 8a of a spout 8 that projects diagonally upward from the spout, and the outer edge of the palate mounting bracket 9 is a guide edge 9 substantially parallel to the axis of the spout 8;
b is provided, and a bent portion 9C bent toward the spout 8 is provided at the upper end of the guide edge 9b, and a recess 11C is provided in a portion of the lower surface of the palate 11 facing the palate mounting bracket 9, and the recess 11C is provided. The lower piece of the U-shaped leaf spring 13, which is fitted into the spout 8 and opens toward the spout 8 side, projects downward from the lower surface of the palate 11 and comes into elastic contact with the guide edge 9, so that the following effects can be expected.

(a) A recess 11C is provided on the lower surface of the palate 11 in a portion facing the palate mounting bracket 9, and the lower piece of the U-shaped leaf spring 13, which is fitted into the recess 11C and opens toward the spout 8, is placed below the lower surface of the palate 11. Since the roof of the mouth 11 is protruded out and brought into elastic contact with the guide edge 9, when the palate 11 is opened, it does not only open through a half-open state, but also connects the tip 9e of the bent portion 9C on the lower piece 13a, the bent portion 9C and the guide edge. As the roof of the mouth 11 is opened, the point of contact with the corner 9f formed by the roof of the mouth 9b moves toward the tip of the lower piece 13a, and the leaf spring 13 operates to gradually reduce the force that lifts up the roof of the mouth 11.

Therefore, there is no need to worry about the palate 11 suddenly opening, and there is no need to worry about high temperature water adhering to the vicinity of the whistle 12 splashing onto the fingers.

(b) When closing, the plate spring 13 is configured to press the palate 11 more strongly as it closes (the base of the lower plate spring piece 13a comes into pressure contact with the metal fitting 9), so the palate 11 strongly presses against the spout. 8, and the whistle sounds well.

(C) A guide edge 9b that is substantially parallel to the axis of the spout 8 is provided on the outer edge of the palate mounting bracket 9, and a bent portion 9C that is bent toward the spout 8 is provided at the upper end of the guide edge 9b. As a result, the palate 11 can be held in a half-open state, so even when boiling water when the whistle 12 is not required, the palate 11 can be kept in a half-open state to prevent boiling water from splashing out through the spout 8. It can be prevented.

(d) Since the palate 11 can be left in a half-open state, it is possible to prevent dirt from getting mixed in even when the whistle 12 is not required to operate in a keratle with a whistle, in which a relatively large-diameter spout 8 is generally used. Direct blowing of steam can also be alleviated.
