Move within 5. That is, since both end portions 2a of the knob portion are formed in a semi-elliptical shape, the knob portion 2 and the shaft 3 move outward in a side view as the knob portion 2 is tilted. When the long axis tips 2b are in contact with each other, the distance d between the two axes is the maximum (FIG. 4B), and the distance d is the minimum during cooking and storage. The shaft 3 moves outward and at the same time is pulled inward by the coil spring which is the urging means 4. Specifically, when the distance d between the two axes is maximum, the tension is maximum, and when the distance d is minimum, the tension is minimum. Therefore, the knob portion 2 is not stable in the intermediate region other than during cooking and storage, and its state is stably maintained only during cooking or storage.

According to the pot lid knob 100, the following effects are exhibited. When the pot lid B is used (during cooking), the knob portion 2 is kept upright and the knob portion 2 does not fall against the user's will, so that the pot lid B can be used safely. can. On the other hand, when the pot lid B is stored, the knob portion 2 is kept in a lying state, so that even when a plurality of pot lids B are stacked and stored, the knob portion 2 does not become an obstacle and is small. Stable storage is possible in space. Similarly, even when the pot lid B is vertically erected and stored, the knob portion 2 is kept lying down, so that stable storage is possible in a small space. The knob portion 2 is not stable in the intermediate region other than during cooking and storage, and its state is kept stable only during cooking or storage, so that the user can easily use the knob with a small force. The state of unit 2 can be switched.

Further, since the tip portion 2d of the knob portion 2 is flattened, when the knob portion 2 shifts from the upright state to the lying state, the tip portions 2d support each other on the surface, so that the knob portion It becomes possible to firmly hold the sleeping state of 2. Further, since the knob portion 2 is configured in an arch shape, it is possible to secure a space for the user to pick the knob portion 2 in the upright state and the lying state of the knob portion 2, so that the pan knob 100 The operability of is improved.

Next, a method of using the pan lid knob 200 will be described. FIG. 12 is a conceptual diagram showing the movement of each portion accompanying the movement of the knob portion of the second embodiment. First, the user removes the existing pan lid knob (not shown) from the pan lid B, and attaches the pan lid knob 200 to the center of the pan lid B by the fixing means 207. When using the pot lid, the user picks up 202c near the top of the knob portion 202, puts the knob portion 202 in an upright state (FIG. 12 (c)), and cooks. At this time, since both end portions 202a of the knob portion 202 are formed in a semi-elliptical shape, the knob portion 202 is maintained in an upright state due to the resistance thereof. Therefore, the knob portion 202 does not fall down without permission against the will of the user.

Next, the user tilts the knob portions 202 so as to open each of the knob portions 202 in order to store the pot lid B after cooking, and moves the knob portions 202 to a sleeping state (FIG. 12 (a)). At this time, since both end portions 202a of the knob portion 202 are formed in a semi-elliptical shape, the knob portion 202 is kept in a lying state due to the resistance thereof. Therefore, even when a plurality of pot lids B are stacked and stored, the knob portion 202 does not become an obstacle, and stable storage is possible in a small space. Further, even when the pot lid B is vertically erected and stored, the knob portion 202 is kept in a lying state, so that stable storage is possible in a small space as described above.

13 is a plan view showing the pan lid knob 300 according to the third embodiment of the present invention, FIG. 14 is a front view thereof, and FIG. 15 is a side view thereof. The pan lid knob 300 has the same configuration as that of the second embodiment except for the bearing 305 and the urging means 304, which will be described later. Therefore, the description thereof will be omitted, and the same components will be designated by the same reference numerals.

The bearing 305 is provided as a recess in the cover 206, and the length in the longitudinal direction is about 2 to 3 times the diameter of the shaft 203, and the length in the lateral direction is substantially the same as the diameter of the shaft 203. It is a rectangular shape with both sides of the short side in a semicircular shape. Further, the diameter of the semicircle is substantially the same as the diameter of the shaft 203. The bearing 305 may be provided as a recess in the cover 206, or may be provided independently so as to stand upright from the main body 21.

As shown in FIG. 13, the urging means 304 is an elastic body connected to the shaft 203 in the vertical direction of the shaft 203 and adjacent to the shaft 203 in a plan view. The urging means 304 is, for example, a leaf spring, a coil spring, or a heat-resistant rubber, and urges the shaft 203 toward the side where the knob portions 202 are in contact with each other (inward direction) in a side view. In the pot lid knob 300, for example, four coil springs are arranged between the adjacent shafts 203.

Since the method of using the pan lid knob 300 is the same as that of the second embodiment, the description thereof will be omitted.

The pan lid knob 400 has the same configuration as that of the second or third embodiment except for the knob portion 402 and the stand portion 408, which will be described later. Therefore, the description thereof will be omitted, and the same components will be designated by the same reference numerals. ..

The knob portion 402 is a pair of bilaterally symmetrical semicircular plate-shaped bodies, and both end portions 402a thereof are semi-elliptical when viewed from the side. The knob portion 402 is set to have a length in the longitudinal direction shorter than the diameter of the main body 201, for example, 30 mm or more and 60 mm or less, and is arranged on the upper part of the main body 201. Further, the knob portion 402 is provided with a plurality of mounting holes 402c for mounting the stand portion 408. The semi-elliptical long axis tip 402b is diagonally downward on the side where the knobs 402 are in contact with each other when the knob portion 402 is upright, and diagonally upward on the side where the knob portions 402 are in contact with each other when lying down. (Fig. 19). Further, the vicinity of the semi-elliptical long axis tip 402b is flattened with a predetermined width (FIG. 19). For example, the predetermined width is 2 mm or more and 5 mm or less. The knob portion 402 is molded from a natural resin or a synthetic resin, and in the case of a synthetic resin, for example, a phenol resin or a silicone rubber is preferably used.

The knob portion 402 may have a semi-elliptical shape, a polygonal shape, or the like, in addition to the semi-annular shape. The long axis tip 402b is formed in the vicinity of the tip in a gear shape or a cam shape. By forming the vicinity of the tip into a gear shape, the knob portions 402 can be more reliably interlocked with each other, which is preferable.

FIG. 21 is a diagram showing a production example of the stand portion 408 of the fourth embodiment. The stand portion 408 has a rectangular flat plate shape, and has an opening / closing structure at one end in the lateral direction. The opening / closing structure is preferably formed in a shape corresponding to the knob portion 402, and is preferably formed to be the same as or slightly larger than the knob portion 402. One piece 408c of the opening / closing structure includes a plurality of convex portions 408a inserted into the mounting hole 402c, and the other piece 408d includes a plurality of concave portions 408b inserted into the mounting hole 402c and fitted with the convex portion 408a.

The stand portion 408 is molded from a natural resin or a synthetic resin, and in the case of a synthetic resin, for example, a phenol resin or a silicone rubber is preferably used. Further, the length of the stand portion 408 in the longitudinal direction is designed to be shorter than the radius of the pot lid B to which the pot lid knob 400 is attached. For example, in the case of the pot lid B having a diameter of 160 mm, the length of the stand portion 408 in the longitudinal direction is preferably 60 mm or more and 80 mm or less, and in the case of the pot lid B having a diameter of 200 mm, the stand portion 408 is used. The length in the longitudinal direction of the above is preferably 80 mm or more and 100 mm or less.

FIG. 22 is a cross-sectional view showing an example of mounting the stand portion 408 of the fourth embodiment to the knob portion 402. The stand portion 408 is attached to the knob portion 402 one by one, and is attached so that the knob portion 402 is sandwiched between the one piece 408c and the other piece 408d. At this time, the stand portion 408 is fixed to the knob portion 402 by inserting and fitting the convex portion 408a and the concave portion 408b through the mounting hole 402c.

Next, a method of using the pan lid knob 400 will be described. The state in which the knob portion 402 is upright (during cooking) and the state in which the knob portion 402 is lying down (during storage) are the same as those in the second or third embodiment, and thus description thereof will be omitted.

As shown in FIG. 20, when the knob portion 402 is tilted by the user in the transition from the upright state (during cooking) to the sleeping state (during storage) of the knob portion 402, the shaft 203 is subjected to the bearing. It moves in 205 (FIG. 20 (d)). That is, since both ends 402a of the knob portion are formed in a semi-elliptical shape, the knob portion 402 and the shaft 203 move outward in side view as the knob portion 402 tilts. At this time, the distance d between the two shafts of the shaft 203 is maximized, and the pressing force of the leaf spring, which is the urging means 204, is also maximized. Therefore, in this intermediate region, the knob portion 402 is in an unstable state.

When the knob portion 402 is further tilted by the user, the long axis tip 402b is in contact with each other (FIG. 20 (c)). At this time, since the vicinity of the long shaft tip 402b is flattened with a predetermined width, the distance d between the two shafts of the shaft 203 is the minimum, and the pressing force of the leaf spring, which is the urging means 204, is also the minimum. Become. Therefore, the knob portion 402 is kept in a stable state. In this state, the user can make the pot lid B self-supporting by using the stand portion 408. That is, the pot lid B becomes self-supporting by being supported by the edge of the pot lid B and one point each of the stand portion 408, for a total of three points.

When the knob portion 402 is further tilted by the user, the shaft 203 moves in the bearing 205 again (FIG. 20 (b)). Similar to the above, the distance d between the two shafts of the shaft 203 is maximized, and the pressing force of the leaf spring, which is the urging means 204, is also maximized. Therefore, the knob portion 402 is in an unstable state even in this intermediate region. Will be. When the knob portion 402 is further tilted by the user, the knob portion 402 is in a lying state (when stored) and is kept stable.

According to the pot lid knob 400, in addition to exhibiting the same effects as those of the second and third embodiments, the pot lid B can be made to stand on its own. Therefore, it is possible to minimize the space occupied by the pot lid B when the pot lid B is temporarily removed from the pot during cooking. Further, by making the pot lid B after washing stand on its own, it is possible to dry efficiently and hygienically.

Although the embodiments according to the present invention have been described above, the present invention is not limited thereto. For example, in the above embodiment, it has been described that the shaft 203 protrudes from both end portions 202a to the left and right sides in a front view, but either the left or right side, that is, either the outer peripheral side or the center side of the main body 201. It may be configured to project to.

Further, in the above embodiment, it has been described that the shafts 3 and 203 are provided substantially at the centers of both ends of the knob portions 2, 202 and 402, but the shafts 3 and 203 may be provided eccentrically. That is, the shafts 3 and 203 are arranged eccentrically from the centers of both ends of the knob portions 2, 202 and 402 so that the urging force (tension or pressing force) of the urging means becomes large in the intermediate region. As the urging force increases, the knobs 2, 202 and 402 in the intermediate region become more unstable, so that the pan lid knob can be operated more quickly.

Further, although the knob 400 for the pot lid has been described based on the second embodiment, the combination is not limited to this. That is, it may be based on the first or third embodiment, and in this case, the effects of the first or third embodiment are also exhibited at the same time.

Further, as shown in FIG. 23, the main body, the knob portion, the stand portion, and the like may be provided with various patterns, or the shape may be similar to that of a lemon or a clover leaf to have a design. By doing this, it becomes possible to change the knob of the pot lid with the same feeling as choosing a plate according to the mood, cooking, and serving place, and it becomes possible to meet a wide variety of demands.
