DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lid for opening and closing the opening of various containers, for example, gyoza pots, tempura pots, cooking pots for high and low temperatures, food containers, tool boxes and the like. The present invention relates to an opening and closing fixture.

[0002]

2. Description of the Related Art Heretofore, this type of lid has been prepared separately from a container, and is generally held by a person and put on or removed from the opening of the container. . However, in the case of a ginger pot for business use, the lid is relatively large and heavy because a certain amount of sealing pressure must be applied during cooking.
For this purpose, the lid of the ginger pot for business use is connected to the pot side via a hinge so that the opening of the pot can be easily opened and closed by, for example, one-handed operation. Many.

[0003]

However, as a hinge mechanism conventionally used for a pot lid of this type, a simple hinge type is used with a simple structure.
Such a simple hinge type has a simple structure and is good, but until the cook completely closes the lid by hand,
Alternatively, the lid must be moved to a completely open position, and even in the open state, the lid may suddenly turn to the closed position due to an accidental external force such as the weight of the lid. . In addition, this type of lid is quite apt to become dirty due to splashing of oil droplets during cooking and needs to be cleaned frequently, but in the case of a simple hinge type, the lid is removed from the pot body. It could not be removed freely, which was inconvenient for cleaning the lid. Moreover, none of these simple hinge types acted to press the lid against the pan and increase the sealing pressure when the lid was closed.

[0004] In view of such a problem of the simple hinge type, conventionally, the lid can be made detachable or can be automatically brought into a completely open state or a closed state only by moving the lid to some extent. In addition, various hinge mechanisms have been developed and proposed which allow additional sealing pressure to be applied to the lid in the closed state, but all have complicated structures or large structures. , Expensive and complicated in handling.

An object of the present invention is to provide a lid opening / closing fixture which can solve the above-mentioned problems of the prior art, is simple in structure, is inexpensive, and is easy to handle.

A rotation control unit having a pair of leaf springs 32 on both sides facing each other with the. In this embodiment, the rotation control section is formed by integrally forming the mounting section 32A and the pair of leaf springs 32 on both sides from a springy sheet material. Together with the part 31, it is fixed to the mounting wall 11.

Furthermore, the lid opening / closing fixture 30 of this embodiment
Comprises two lid connections 34, one end of which is pivotally mounted on the shaft 35 and the other end of which is attached to the lid 20 which opens and closes the opening of the gory pan 10. I have. Each lid connection portion 34 has a notch portion 34B between one end and the other end, and a block portion 34A on one end side from the notch portion 34B is provided between each corresponding pair of leaf springs 32. Hold the lid 20 with the ginger pot 10
Of the first set of opposing sides A for holding in a closed state with respect to
And a lid 2 sandwiched between a pair of corresponding leaf springs 32.
A second set of opposing sides B for holding 0 in the open state with respect to the gory pan 10 is formed.

At the other end of each lid connecting portion 34, a screw mounting holding hole 34C for mounting and holding a screw 36 with a knob is provided.
Are formed. The other end of each lid connection portion 34 is provided with a screw 36 with a knob held in the screw attachment holding hole 34C.
By screwing into a screw hole 22 formed in a corresponding portion of the cover 20, the cover 20 is detachably attached to the cover 20.

The first set of opposing sides A and the second set of opposing sides B formed in the block portion 34A of each lid connection portion 34 are provided with a desired maximum opening relative to the opening of the pot 10 of the lid 20. A predetermined angle is formed according to the angle.
In this embodiment, the angle between the opposite side A and the opposite side B is
The obtuse angle is set. In this case, the maximum opening angle of the lid 20 is smaller than 90 degrees as shown in FIG. As described above, the maximum opening angle of the lid 20 can be variously changed by variously changing the angle between the opposite side A and the opposite side B.

Next, the overall operation of the lid opening / closing fixture 30 having such a structure will be described. First, when the lid 20 is completely closed with respect to the opening of the gory pan 10 as shown in FIG. 1, the opposing sides A of the first set of the block portions 34A of the lid connecting portions 34 Corresponding one
Each lid connection portion 3 is sandwiched by a pair of leaf springs 32.
4 is adapted to be subjected to an elastic shifting force such that the lid 20 connected thereto is pressed against the opening of the gory pan 10. Therefore, the sealing pressure of the lid 20 with respect to the pan 10 is determined by
This is obtained by adding the elastic displacement force.

Next, when the lid 20 is to be opened with the handle 21 of the lid 20 by hand, each lid connecting portion 34 is about to be rotated about the shaft 35. This rotational force is generated by each pair of leaf springs 32 against the elastic shift force sandwiching the first pair of opposing sides A of the block portion 34A of each lid connection portion 34, respectively. Block part 34A
Can be rotated about the shaft 35. At this time, since the tip of one of the pair of leaf springs 32 (the upper leaf spring in FIG. 1) can escape into the corresponding notch portion 34B of each lid connection portion 34, each block portion 34A can rotate between each pair of leaf springs 32.

As described above, while each of the lid connecting portions 34 is rotating around the shaft 35 in the opening direction of the lid 20,
When each pair of leaf springs 32 is separated from the corresponding side A of the first set of the corresponding block portion 34A of each lid connection portion 34 and starts to make a sandwiching contact with the opposite side B of the second set. ,
Each pair of leaf springs 32 is adapted to exert a resilient shift force on the opposing side B of the second set sufficient to cause the lid 20 to automatically transition to the open state. . Therefore, even if the user releases his / her hand from the handle 21 before the lid is completely opened, the lid 20 does not stop halfway or return to the closed state due to the weight of the lid 20 itself. The shifting force will automatically open to the fully open position. FIG. 3 shows such a completely opened state of the lid 20. When the lid 20 is fully opened as shown in FIG. 3, the opposing sides B of the second set of the block portions 34A of each lid connecting portion 34 are sandwiched by each pair of leaf springs 32, and 20 is fixedly held in its open state by the elastic clamping force of each leaf spring 32.

When the lid 20 is to be closed with the handle 21 of the lid 20 by hand from the open state shown in FIG. 3, each lid connecting portion 34 is turned around the shaft 35 in the opposite direction. Trying to be This rotational force is generated by each pair of leaf springs 32 against the elastic shift force that sandwiches the second pair of opposing sides B of the block portion 34A of each lid connection portion 34, and the respective lid connection portions 34 Is rotated about the shaft 35. At this time, the tip of one of the pair of leaf springs 32 (the upper leaf spring in FIG. 1) can escape from the corresponding notch portion 34B of each lid connection portion 34 to the outside. Block part 34
A can rotate between each pair of leaf springs 32. In this manner, each lid connection portion 34 is
During rotation of the lid 20 in the closing direction around the
When the pair of leaf springs 32 move away from the corresponding side B of the second set of the corresponding block portion 34A of each lid connection portion 34 and begin to sandwich and contact the opposite side A of the first set, 1
The pair of leaf springs 32 is configured to exert a large enough elastic shift force on the first pair of opposing sides A to automatically shift the lid 20 to the closed state. Therefore, even if the user releases his / her hand from the handle portion 21 before the lid is completely closed, the lid 20 does not stop and return to the open state without stopping halfway. Automatically closes to the fully closed position.

If it is desired to clean the dirty lid 20 after use in cooking, the screw 36 with the knob is removed from the screw hole 22 of the lid 20 so as to be removed from the top of the pot 10 and to be cleaned in another washing place. The lid 20 after the cleaning can be easily connected and fixed to each lid connection portion 34 by screwing the screw 36 with a knob into the screw hole 22 of the corresponding lid 20 again. .
