DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a kettle for rotatably supporting a handle on a body.

[0002]

2. Description of the Related Art A kettle 1 is composed of a container 3 with a gate 2, a pair of supports 4 and 4 riveted to the gate side and the opposite side, and a lid 5 for closing the opening of the container 3. ,
It has a configuration having a handle 7 rotatably supported by the supports 4, 4 via rivets 6, 6.

The supports 4 and 4 are die-cast aluminum alloy products and have rivet holes.
Washers 8, 8, between the supports 4, 4 and the handle 7, between the heads of the rivets 6, 6, and the outer surfaces of the supports 4, 4, and between the handle 7 and the end of the rivet 6. To another washer 9, 9, 9,
The rivet is swaged so that the rivet head faces outward with the interposition of the rivet 9.

[0004]

In the conventional kettle, the head of the rivet protrudes from the support and has a poor appearance.
Further, the washer interposed between the handle and the support changes the turning resistance of the handle according to the state of the rivet, and it is difficult to provide the handle with a constant turning resistance. In addition, the use of washers leads to an increase in the number of parts of the kettle. Therefore, an object of the present invention is to provide a kettle that has a good appearance, stabilizes the turning resistance of the handle, and can reduce the number of parts.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a container with a sprue, a pair of supports fixed to the sprue side and the opposite side, and a rivet connected to the support. In a kettle having a handle rotatably supported by a rivet, the head of the rivet is housed in the counterbore of the support, and the depth of the counterbore provided on the outer surface of the support is greater than the height of the rivet head. 0.1 mm to 0.8 mm deep, preferably 0.2 mm to 0.5 mm deep, the end of the rivet opposite to the head is fixed to the handle and the diameter of the head is Use a means that is smaller than the diameter of the counterbore.

[0006]

According to the first to fourth aspects of the present invention, the rivet head is housed in the hole of the support, and the rivet can be caulked in a form in which the outer surface of the rivet is aligned with the outer surface of the support. This is effective in maintaining the rotation resistance of the handle at a preferable constant value.

According to the second or third aspect of the present invention which regulates the depth of the counterbore, the head of the rivet can be housed in a protruding state or the handle can be rotated with good sensitivity without extending the head from the support. Provide the best form.

According to the fifth and sixth aspects of the present invention, the protrusion is integrally provided on the side surface of the support, so that the interposition of the washer is unnecessary, the number of parts is reduced, and the conventional washer and the inner surface of the support are formed. Works to reduce contact resistance. The rivet hole diameter of the support is provided to be larger than the rivet hole diameter of the handle, and further, the interposition of a washer is unnecessary, and the rivet tip caulking is firmly attached. The invention according to claim 8, which has a stopper provided on the side surface of the support tool, functions to effectively restrict the set angle of rotation of the handle.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The basic structure of a kettle according to the present invention is substantially the same as that of the embodiment shown in FIG. 3, and only the improved components will be described with reference to FIGS. The support 41 riveted to the container 3 has a counterbore 42 on the outer surface thereof, and a rivet hole is formed concentrically with the center of the counterbore 42. The counterbore hole 42 is a storage recess approximately equal to the head of the rivet 6, and the depth of the counterbore hole 42 is 0.1 mm to 0.8 mm deeper than the height of the rivet 6 head, preferably 0.2 mm. The depth of the counterbore is set at a depth of 0.5 mm from the depth. This is effective when the rivet 6 is swaged so that the top surface of the head of the rivet 6 substantially coincides with the outer surface of the support 41 and the swage amount is maintained at a constant amount.
That is, when the gap dimension is less than 0.1 mm, the handle is always hard to turn, and in some cases, does not turn. on the other hand,
At a depth of 0.8 mm or more, the handle will rotate without resistance, and the handle will hit the body strongly, creating scratches and dents. Also,
Preferably, when the gap size is 0.2 mm to 0.5 mm deep, a good and smooth rotation of the handle can be obtained by the contact resistance of the support tool and the handle during the rotation.

A circular projection 43 concentric with the rivet hole is provided on the inner surface of the support 41, that is, on the side opposite to the counterbore hole, and this projection 43 is brought into contact with the side surface of the handle 7. Note that the protrusion 43 is further provided with a protruding ring or a plurality of protrusions and is brought into contact with the side surface of the handle 7 to improve rotation. Protrusion 43
A stopper 44 is provided integrally with the support 7 at the lower part of the support. The stopper 44 is provided on a horizontal surface 45 facing the end surface 71 of the handle 7.
And ridges 46 provided at both ends of the horizontal surface 45. One corner of the end face 71 of the handle 7 is a right-angled part 72, and the other corner is formed into an arc part 73 concentric with the rivet 6. In this example, when the handle 7 is rotated clockwise as viewed in FIG. The handle 7 is held substantially horizontally. When the handle 7 is rotated in the counterclockwise direction as viewed in FIG. regulate.

A seat plate 91 such as an elastic metal washer is preferably interposed between the head of the rivet 6 and the counterbore 42. The seat plate 91 of this wave washer has a thickness of 0.15 mm and has a wavy shape, and the gap between the waves is 0.85 mm so that the contact between the handle 7 and the projection 43 is made elastic. Although not shown, the counterbore 42 is replaced with the washer washer 91.
The bottom surface may be formed integrally with a protruding ring or a plurality of protrusions by molding or press working so that the contact surface is set small, and the rotation can be made smoother. Also, a washer 91 made of an elastic body such as a silicone resin can be used instead of the wave washer. Hands supported as in the example shown
It was rotated twice, but its resistance was 270 g to 11
By maintaining the value of 0 g, the user can continue to give the user a moderate resistance to rotation. The rivet hole diameter of the support 41 and the handle 7
The rivet hole diameter of the support 41 is set to a large diameter, and the rivet hole diameter of the handle 7 is slightly reduced, preferably
It is better to make the diameter smaller by 0.5 mm to increase the caulking strength, and to omit the seat plate on the caulking side at the rivet tip, and to improve the caulking accuracy.

[0012]

The kettle according to the present invention has a good appearance, the number of parts is small, and the turning resistance of the handle can be kept constant.
