Description

[Detailed explanation of the idea] [Industrial application field] This invention concerns a whistling kettle.

[Conventional technology and issues with the invention]

In the conventional whistle kettle, as shown in FIG. 3, a palate 53 having a whistle is rotatably supported via a pin 54 on a palate mounting bracket 52 fixed to the top surface of a pouring barrel 51. It is held open and closed by a leaf spring 55 and a cam surface 56 of the palate 53.

When assembling the above-mentioned whistling kettle, insert the supporting part of the palate 53 into the palate mounting bracket 52, and as shown in FIG.
After passing it through, it was necessary to caulk its both ends or press-fit a split pin 54a as shown in FIG. 5 to prevent it from coming off, which was a time-consuming task.

Therefore, the object of this invention is to improve the whistling kettle so that it can be easily used with a palate attachment.

[Means to solve the problem]

In order to solve the above problem, this invention fixes a pallet mounting bracket having a bearing on the tip side of the pouring tube to the top surface of the pouring tube, and attaches the bearing to the pallet with a whistle that opens and closes the mouth of the pouring tube. A shaft is fitted to support the palate in a vertically rotatable manner, and the palate is provided with a protrusion behind the shaft, and this protrusion is constantly pressed between the open and closed states of the palate, and the palate is in the open state. and a whistle kettle comprising a leaf spring attached to the top surface of the pouring barrel such that the axis of the shaft is located between the pressing lines in the closed state, the shaft passing through a rear portion around the bearing. A structure was adopted in which a notch of the same size was formed.

[Effect]

With the whistle kettle constructed as described above, when the protrusion of the palate contacts the leaf spring and is pushed in, and the shaft is brought to the notch in the bearing, the shaft will naturally fit into the bearing due to the pressing force of the leaf spring. It will fit in and maintain that state.

In addition, the palate attached to the palate mounting bracket is
Since the axial center of the shaft is located between the pressure lines in the open state and the closed state, the palate is biased in the opening direction or the closing direction at the midpoint between the open state and the closed state.

〔Example〕

Examples will be described below with reference to the drawings.

As shown in FIG. 1a, a leaf spring 20 folded diagonally backward is attached to the upper surface of the pouring barrel 11 of the kettle 10, and a plate material is bent to cover the leaf spring 20. The palate mounting bracket 30 is fixed. As shown in FIG. 1b, this palate mounting bracket 30 has semicircular bearings 31 formed by folding back a part of the plate material on both sides of the tip.

Further, the palate 40 having a whistle is provided with a shaft 41 that extends left and right and is supported by the bearing 31 on the rear support part, and the rear of the shaft 41 is pressed by the leaf spring 20. A projection 42 is provided.

Furthermore, this protrusion 42 and the leaf spring 20 are
As shown by solid lines and chain lines in the figure, the axis of the shaft 41 is located between the pressing lines A and B when the palate 40 is in the open and closed states. Therefore, the palate 40 is biased in the opening direction or the closing direction at the midpoint between the open state and the closed state,
Each state is maintained.

In this embodiment, in order to attach the palate 40 to the palate mounting bracket 30, as shown in FIG. The shaft 41 is automatically moved into the bearing 3 by the pressing force of the leaf spring 20.
1 and maintains that state.

〔effect〕

As mentioned above, the whistle kettle of this invention is
A shaft is provided on the roof of the mouth that protrudes from side to side, a bearing with a notch into which the shaft can be fitted is provided in the roof mounting bracket, and the shaft fitted into the bearing is held by the biasing force of a leaf spring. Therefore, it is easy to attach the palate, and there is no need for the conventional troublesome work of caulking both ends of the pin or press-fitting a cotter pin.

Claims (1)

[Scope of utility model registration request] A palate mounting bracket having a bearing on the tip side of the pouring tube is fixed to the top surface of the pouring tube, and a palate with a whistle that opens and closes the mouth of the pouring tube is fitted into the bearing to support the palate so as to be able to rotate up and down. The palate is provided with a protrusion behind the axis, and this protrusion is always pressed between the open and closed states of the palate, and the axis of the axis is provided between the pressure lines of the open and closed states. A whistling kettle comprising a leaf spring arranged so that the center is located is attached to the top surface of the pouring barrel, characterized in that a notch large enough for the shaft to pass through is formed in the rear part around the bearing. A whistling kettle.
