Description

[Detailed description of the invention] This invention relates to an improvement of a noddle device for a water boiler.

Those with a structure that attaches the handle directly to the body of the water heater not only eliminates the use of metal fittings, but also eliminates the protruding parts that are easy to touch with fingers and the cuffs of clothing, so it is structurally better. It is very advantageous.

Therefore, a simple riveting means is used as a means for attaching the handle to the container body, but this riveting means has a problem in adjusting the riveting force.

In other words, if the caulking force of the rivets is strong, the handle will become stiff and difficult to turn, making handling of the vessel extremely inconvenient.

On the other hand, if the caulking is weak, the handle will turn easily, but
It will be in an unstable state, so if you put it on a stove, etc., even if it is left upright, the slightest vibration will cause it to fall to the side.
may be exposed to the risk of overheating.

This invention was made to solve the above problem, and even if the handle is riveted, it is possible to reliably obtain an appropriate handle holding force without being affected by the riveting force of the rivet. The main purpose of this invention is to provide a water heater handle device that can also set the rotation range of the handle.

Hereinafter, this invention will be explained in detail based on the drawings showing examples thereof.

In Figures 1 to 5, 1 is the water heater body;
2 is a spout, 3 is a lid for opening a water jug, and 4 is a handle made of a metal strip bent into a U-shape, and plate portions 4a on both sides of the handle are attached to the container body by means of rivets. 1
is attached directly to the

That is, this riveting means uses stepped rivets 5, disc-shaped seats 6, flat washers 7 and 8, and a corrugated elastic washer 9.

The stepped stud 5 has a shaft portion connected to the head 5a formed in a stepped shape with a large diameter shaft portion 5b and a small diameter shaft portion 5c.

The disk-shaped seat 6 has a small diameter shaft portion 5b of the previous record 5 in its center.
There is a shaft hole 6a through which the shaft hole 6a is inserted, and the end surface that is applied to the curved outer surface of the container body 1 is formed in the same curved surface, and is a detent that is fitted into the shaft hole-equipped recess 1a provided in the container body 1. A convex portion 6b is formed on the circumference of the opposite end surface.
For the purpose described later, an arcuate notch 6c is formed spanning a central angle of 90 degrees.

On the other hand, the plate portion 4a of the handle to be riveted has a shaft hole 4b through which the large-diameter shaft portion 5b of the rivet 5 is inserted, and a protrusion 4c formed by cutting out the plate is located near the shaft hole 4b into the receiving seat 6. It is provided in a direction that can be engaged with the arcuate notch 6c.

To rivet the handle 4 to the container body 1, the handle plate portion 4a, the flat washer 8 disposed on the outside thereof, and the flat washer 7 and the wave-shaped washer 9 disposed on the inside thereof Diameter shaft portion 5
b, and the disc-shaped catch seat 6 is inserted into and supported by the small diameter shaft portion 5c of the stud 5.
At the same time, the anti-rotation convex portion 6b is fitted into the recess 1a with the shaft hole of the container body 1, and the small diameter shaft portion 5c of the rivet is inserted inside the container body through the shaft hole. The protruding tip is caulked to form the deformed head 5d, and the tightening during the caulking process is performed by force, so that the seat 6 inserted into the small diameter shaft portion 5c is brought into contact with the large diameter shaft portion 5b. Although it is firmly held between the stepped surface and the outer surface of the vessel,
The handle plate portion 4a is inserted into the large diameter shaft portion 5b,
Since no tightening force is applied to the flat washers 7, 8 and the wave-shaped washer 9, the handle plate portion 4a is supported by the large diameter shaft portion 5b, and the rivet head 5a and catch seat 6 In between, it is clamped in a compressed state by a corrugated washer 9.

Further, the tip of the protrusion 4C protruding from the handle plate portion 4a is protruded into the circular arc notch 6c of the catch seat 6.

Therefore, according to the above-mentioned riveting means, even if the nodule is riveted, the nodule does not receive the crimping force of the rivet.
Since it is in a freely rotatable state and an appropriate strength of holding force is reliably obtained by the elastic action of the corrugated washer, it can be stably held at the rotated angular position.

Further, according to the above configuration, the rotation angle range of the handle is
Since the protrusion 4c of the handle plate portion 4a is limited where it engages with both ends of the arc notch 6c of the catch seat 6, by appropriately determining the center angle of the arc notch 6c, ... the handle can be regulated within an angular range that does not pose a risk of overheating, i.e. within a safe angular range between the upright and horizontal positions.

Furthermore, the convex portion 6b provided on the end face of the catch seat 6 is
The one fitted in the recess 1a serves to strengthen the prevention of rotation of the catch seat 6, and the mounting angle can be easily set.

The one shown in FIG. 6 is another embodiment of this invention, in which a protrusion 6d is provided on the end face of the seat 6, and a circular arc concentric with the shaft hole 4b is provided on the handle plate portion 4a. A hole 4d is drilled, and the projection 6d is inserted into the arcuate hole 4d, so that the rotation angle range of the handle is regulated by the engagement guide between the arcuate hole 4d and the projection 6d.

What is shown in FIGS. 7 to 9 is another embodiment of this invention, in which the end face of the catch seat 6 facing the handle, and the center shaft hole 6a. A projecting wall portion 6e having a center angle of 90 degrees is formed, and the rotation angle range of the handle is restricted by this projecting wall portion 6e.

As mentioned above, according to this invention, in a device in which the nodle is rotatably supported on the body of the water heater by means of rivets, the shank of the rivet is attached to the head of the water heater. The large-diameter shaft portion connected to the large-diameter shaft portion and the small-diameter shaft portion connected thereto are formed in a stepped shape, and the catch seat fitted into the small-diameter shaft portion is caused by the caulking force of the rivet to cause the outside surface of the vessel and the rivet shaft portion to form a stepped shape. It is clamped and fixed between the attached surface, and the large diameter shaft part...
A handle and a pressure member that presses the handle in the axial direction are rotatably fitted in a state where they are held between the end face of the catch seat and the head of the stud, and the handle is attached to the catch seat and the handle so that the handle can rotate. Since the handle is equipped with a means to regulate the range of movement angle, even if the handle is riveted, it will not be affected by the crimping force of the rivets, and will ensure that the handle is properly supported. The rotation operation range can also be set, which can contribute to improving the handle support structure.
