Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a structure in which a resin handle is integrally attached to a pot using screws.

(Prior Art) As shown in FIG. 3, the conventional resin handle mounting structure includes a screw hole 11 formed protruding from the side surface of the pot body 10 and a screw hole formed through the base 12a of the handle 12. This is done by screwing in screws 14 from 13. Further, a cylindrical or prismatic joint fitting 15 formed to match the cross-sectional shape of the handle base 12a is interposed between the side surface of the pot body 10 and the handle 12.

(Problems to be solved by the invention) In the above structure, due to the difference in coefficient of thermal expansion between the pot body 10 and the joint metal fittings 15 made of metal and the handle 12 made of resin, a difference occurs on the handle side each time cooking is performed. When expansion and contraction occur and this is repeated over a long period of use, a gap 16 is created in the area where the head 14a of the screw 14 and the end of the fitting 15 come into contact, as shown in FIG. 12 begins to slacken.

For this reason, even if the joint fitting 15 is used to prevent the handle 12 from rotating, its role will not be fulfilled, and the handle 12 will swing sideways, making it difficult to use the pot.In addition, the reaction of the sideways swing will cause the contents of the pot to spill out. There are times when it can be dangerous.

(Means for solving the problem) This invention was devised to solve the above-mentioned conventional drawbacks, and its purpose is to fix the handle to the pot body with screws. However, we have created a new pot that does not loosen due to heat, does not require extensive changes to the handle structure, and can always be securely attached to the pot body by adopting a simple method. The purpose is to provide a handle mounting structure.

The features of this invention for the above purpose are that while a screw receiving member is provided protruding from the side of the pot body, a metal seat plate with both ends bent is placed inside the base of the end face of the screw hole penetrated through the base of the resin handle. The screw receiver member is provided integrally with both bent ends embedded in the handle, and the handle is brought into contact with the side surface of the pot body through a joint fitting having a large contact surface with the handle, and the screw receiver member is inserted through the screw hole and the metal seat plate. It is secured to the side of the pot body using a screw that is screwed into the pot and whose head is pressed into contact with the metal seat plate.

(Function) In the above structure, the metal seat plate is embedded integrally in the base of the handle, and the part to which the head of the screw is pressed is a metal plate, so the coefficient of thermal expansion between the screw side and the metal seat plate side is There is not as much difference as there is with resin, and both expand and contract in the same state repeatedly, so no slack occurs.

Furthermore, since the metal seat plate is embedded and integrated with the handle base, even if there is a difference in coefficient of thermal expansion, it is less likely to have as much of an effect as it would if they were in contact with each other, and the metal seat plate will not loosen.

Furthermore, since the handle-side contact end surface of the joint fitting is made large to increase the contact area with the handle base end surface, there is no biting during thermal expansion, and gaps are less likely to form on the handle base end surface.

As a result, the handle is always securely attached to the pot body regardless of the difference in coefficient of thermal expansion, and no sideways vibration occurs.

Further, this invention will be explained in detail with reference to embodiments shown in FIGS. 1 and 2.

(Example) 1 is a metal pot body made of aluminum etc.
A screw receiving member 2 is provided protruding from the upper side surface.

Reference numeral 3 denotes a handle made of synthetic resin, and a screw hole 4 is provided laterally through the base 3a. At the base 3a of the inner end surface of this screw hole 4, there is a metal seat plate 5 with both ends bent.
However, both bent ends thereof are embedded in the base 3a and provided integrally, and a screw 6 for attachment can be screwed into the screw receiving member 2 through the metal seat plate 5.

Reference numeral 7 denotes a joint fitting, which is formed into a cylindrical shape to match the cross-sectional shape of the base 3a of the handle 3.
The end surface 7a on the side that comes into contact with is formed to have as wide an area as possible.

In the example shown in FIG. 1, the end of the joint fitting 7 made of a metal plate is bent inward to form a large contact end surface with the handle 3, and in the example shown in FIG. The joint fitting 7 is formed thick to increase the area of the contact end surface.

The above handle 3 is attached to the pot body 1 by attaching the handle 3 to the base 3.
This can be easily done by screwing the screw 6 inserted into the screw hole 4 of a into the screw receiving member 2 on the side surface of the pot body through the metal seat plate 5.

Further, the head 6a of the screw 6 is pressed against the metal seat plate 5, and the handle 3 is always fastened and fixed to the side surface of the pot body.

In the above embodiment, the metal seat plate 5 is embedded in the inner end of the base 3a, but the metal seat plate 5 may be embedded in the outer end of the base.

(Effect of the invention) As described above, this invention has the head 6a of the mounting screw 6 mounted on the metal seat plate 5 embedded in the handle 3.
are pressed together, and the contact end surface 7a of the joint fitting 7 is formed large to prevent it from biting into the base 3a, so that as the heat rises and falls during cooking,
Even if the handle 3 repeatedly expands and contracts differently from the screw screw 6 and the fitting 7, there is no big difference in expansion and contraction between the screw screw 6 and the metal seat plate 5, so the screw head 6a and the metal seat plate 5 There will be no gap between the two.

Moreover, since the metal seat plate 5 is embedded integrally in the base 3a, it will not loosen even if the base 3a expands or contracts.

Furthermore, since the contact surface of the fitting 7 is made large, even if the handle side expands, it will not enter the end face of the base 3a, and heat transfer via the fitting 7 will be dispersed, so that the end face of the base will be Hard to burn.

Further, since it is only necessary to embed the metal seat plate and to enlarge the end face of the joint fitting, it has the advantage that the structure is not particularly complicated compared to conventional ones.
