The pan lid knob 100 is a main body 1 having bearings 5 on both side surfaces, and a pair of semi-annular plate-like bodies disposed on the periphery of the main body 1 and the shape of each end 2a is semi-elliptical in the thickness direction. A knob portion 2 serving as a curved surface, a shaft 3 provided in the vicinity of both end portions 2a of the knob portion 2 and substantially at the center of the semi-elliptical shape, and perpendicular to the thickness direction of the knob portion 2, and the shaft 3 It comprises a biasing means 4 for biasing, a cover 6 having a hole through which the shaft 3 is inserted and capable of covering the main body 1, and a fixing means 7 disposed at the center of the main body 1.

  FIG. 3 is a configuration diagram showing the main body 1 according to Embodiment 1 of the present invention, in which (a) is a side view thereof, (b) is a plan view thereof, and (c) is a perspective view thereof. The main body 1 is a box-like body having bearings 5 to be described later on both side surfaces and a hole 1b through which a fixing means 7 to be described later is inserted in the center. The shape of the main body 1 is a box-shaped body having a pair of sides as curves in plan view, but is not limited to this, and an elliptical shape, a polygonal shape, a star shape, or the like can also be adopted. Further, the dimensions of the main body 1 are, for example, a vertical width of 40 mm to 70 mm, a horizontal width of 40 mm to 70 mm, and a height of 5 mm to 15 mm. The main body 1 is molded from natural resin or synthetic resin, and in the case of synthetic resin, it is preferable to use, for example, phenol resin or silicone rubber.

The bearings 5 provided on both side surfaces of the main body 1 are provided as concave portions in the main body 1, and the length in the short direction is approximately the same as the diameter of the portion 3 a of the shaft 3 to be described later. Is about 2 to 5 times the diameter of the 3a portion of the shaft 3 (FIG. 3A). Moreover, since one side in the longitudinal direction is open, it can be inserted into the bearing 5 in a state where the knob portion 2 and the biasing means 4 described later are connected, and the pan lid knob 100 can be easily assembled ( FIG. 3 (c)).

FIG. 4 is a configuration diagram showing the knob portion 2 and the shaft 3 according to Embodiment 1 of the present invention. FIG. 5 is a configuration diagram showing the knob portion 2, the shaft 3, and the urging means 4 according to Embodiment 1 of the present invention. FIG. 6 is a conceptual diagram showing the movement of the pan lid knob 100 according to Embodiment 1 of the present invention. The knob portion 2 is a pair of semi-circular plate-like bodies that are symmetrical to each other, and both end portions 2a thereof are semi-elliptical in a side view (thickness direction). The knob portion 2 is disposed on the periphery of the main body 1. The semi-elliptical long-axis tip 2b is obliquely downward on the side where the knobs 2 are in contact with each other when the knobs 2 are upright, and obliquely upward on the side where the knobs 2 are in contact with each other. (FIG. 6). The long shaft tip 2b is formed in a gear shape or a cam shape in the vicinity of the tip. It is preferable to make the vicinity of the tip gear-like because the knob portions 2 can be interlocked with each other more reliably.

The tip 2d of the knob 2 is flat. By adopting such a configuration, when the knob portion 2 shifts from the standing state to the sleeping state, the distal end portions 2d support each other on the surface, whereby the knob portion 2 can be firmly held in the sleeping state. (FIG. 6). The knob portion 2 can adopt a semi-elliptical shape or a polygonal shape in addition to a semi-annular shape, and a combination of these shapes different from each other.

Further, the semi-annular apex vicinity 2c of the knob portion 2 is configured in an arch shape in a side view (FIGS. 4A and 4C). With this configuration, a space in which a user's finger can be inserted can be secured between the knob portions 2 in the standing state of the knob portion 2, and when the knob portion 2 is in the sleeping state, the knob portion 2 can be secured. Since a space in which a user's finger can be inserted can be secured between the pan lid B and the pan lid B, the knob portion 2 can be easily picked, and the operability of the pan lid knob 100 is improved. In addition, the said structure can also employ | adopt the waveform shape which provided multiple undulations, the mountain shape which sharpened the peak of undulations, etc. Further, the knob portion 2 can be more easily picked by applying anti-slip processing such as rib groove processing to the semi-annular top vicinity 2c. The knob portion 2 is molded from a natural resin or a synthetic resin. In the case of a synthetic resin, it is preferable to use, for example, a phenol resin or silicone rubber.

The shaft 3 is provided substantially at the center of both end portions 2a of the knob portion 2 in a side view, and projects in parallel to the longitudinal direction of the knob portion 2 in a plan view and from the both end portions 2a to a semi-annular center side. (FIG. 4). The shape of the shaft 3 is a two-stage cylindrical shape in which the portion in contact with the knob portion 2 is thick (3a) and the tip side is thin (3b). For example, the diameter of the portion 3a in contact with the knob portion 2 is 3 mm or more and 8 mm or less, and the diameter of the tip side 3b is 1 mm or more and 5 mm or less. As shown in FIG. 5, a biasing means 4 to be described later is connected to the distal end side 3b.

By using the two-stage cylindrical configuration, when the pan lid knob 100 is used, the load of the pan lid B is supported by the portion 3a that is in contact with the knob portion 2, so that it can be used stably and stably. Further, by making the tip side 3b narrow, it is possible to provide a smaller pan lid knob 100 corresponding to a coil spring having a small diameter (biasing means 4) and the like, and saving space during storage. Can be realized. The shape of the shaft 3 is not limited to the above, and may be a two-stage prismatic shape. Moreover, it is good also as a structure which gives the groove | channel processing of the circumferential direction, etc. for enabling the connection of the urging means 4 in the vicinity of the front-end | tip of a column shape or a prismatic shape (illustration omitted). Further, as shown in FIG. 4, a shaft cover 3c having the same diameter as that of the portion 3a in contact with the knob portion 2 that can cover the distal end side 3b may be provided. By adopting such a configuration, dirt or the like during use of the pan lid knob 100 is less likely to adhere to the biasing means 4, and cleaning and maintenance are facilitated, and corrosion of the biasing means 4 can be suppressed. The cover knob 100 can be used over a long period of time.

Further, the shaft 3 may be fixed to the surface of the knob portion 2 in addition to being integrally molded with the knob portion 2. The shaft 3 is made of metal, natural resin or synthetic resin. For example, in the case of metal, iron, steel, aluminum or stainless steel is preferably used, and in the case of synthetic resin, phenol resin or silicone rubber is preferably used.

As shown in FIG. 5, the urging means 4 is an elastic body connected to the adjacent shaft 3 in a direction orthogonal to the shaft 3 in a plan view. The urging means 4 is, for example, a coil spring, a leaf spring, or heat resistant rubber, and urges the shaft 3 to a side (inward direction) where the knob portions 2 are in contact with each other in a side view. In the pan lid knob 100, for example, two coil springs are arranged between the adjacent shafts 3.

7A and 7B are configuration diagrams showing the cover 6 according to Embodiment 1 of the present invention, in which FIG. 7A is a side view thereof, FIG. 7B is a plan view thereof, and FIG. 7C is a perspective view thereof. The cover 6 is a housing having a hole 5a through which the shaft 3 is inserted and which prevents the shaft 3 from shifting in the lateral direction in a side view. The hole 5a is formed to be slightly larger than the diameter of the 3a portion of the shaft 3 by an inverted U-shaped notch from the bottom side of the cover 6. For example, the diameter of the hole 5a is 3.1 mm or more and 8. 1 mm or less. The cover 6 is molded into a shape corresponding to the main body 1 and capable of covering the main body 1. For example, as shown in FIG. 7, an elliptical shape, a polygonal shape, a star shape, or the like can be adopted in addition to a shape having a pair of sides as a curve in a plan view. The cover 6 is molded from natural resin or synthetic resin. In the case of synthetic resin, it is preferable to use, for example, phenol resin or silicone rubber.

As an assembly procedure of the pan lid knob 100 performed by the user or the like, after inserting the knob portion 2 connected by the biasing means 4 into the bearing 5, the cover 6 is put on the main body 1 (FIG. 1, Figure 2). By setting it as the said structure, since the shift | offset | difference to the horizontal direction of the axis | shaft 3 is suppressed in a side view, the stable use of the pan lid knob 100 is attained. Further, in order to suppress the entry of dirt or the like into the bearing 5, dirt or the like during use of the pan lid knob 100 is difficult to adhere to the biasing means 4, and cleaning and maintenance become easy, and the biasing means 4 Therefore, the pan lid knob 100 can be used over a long period of time.

The fixing means 7 is a screw disposed in the center of the main body 1 and inside the cover 6 and protruding downward from the hole 1b. A receiving portion 7a that is screwed with the fixing means 7 is disposed at the protruding tip (FIG. 6). A washer may be disposed between the fixing means 7 and the receiving portion 7a. Moreover, the said fixing means 7 is good also as a structure generally used for the fastener of what is called a pin badge. That is, the fixing means 7 has a configuration in which a notch is provided in a part of the bar shape or a structure in which a circumferential groove is provided in a part of the bar shape. In this case, the receiving portion 7a has a protrusion that fits into the notch or the groove. By setting it as the said structure, the attachment or detachment to the pan lid B of the pan lid knob 100 can be performed easily. The fixing means 7 may be a magnetic force. That is, the fixing means 7 may be a magnet, and the metal receiving portion 7a may be fixed to the pan lid B. In this case, the hole 1b is not formed. By using the fixing means 7 as a magnetic force, the pan lid knob 100 can be easily and quickly attached to and detached from the pan lid B.

Next, a method of using the pan lid knob 100 will be described. FIG. 8 is a conceptual diagram showing the movement of each part accompanying the movement of the knob part of the first embodiment. First, the user removes the existing pan lid knob (not shown) from the pan lid B and attaches the pan lid knob 100 to the pan lid B by the fixing means 7. When the pan lid B is used, the user picks up the vicinity 2c of the top of the knob portion 2 to bring the knob portion 2 into an upright state (FIG. 8C) and cooks. At this time, since both end portions 2a of the knob portion 2 are formed in a semi-elliptical shape, the knob portion 2 is maintained in an upright state by its resistance. Therefore, the knob part 2 will not fall down against the user's will.

Next, the user knocks down the knobs 2 to open the pot lids B in order to finish cooking and store the pan lids B, and moves the knobs 2 to the sleeping state (FIG. 4A). At this time, since both end portions 2a of the knob portion 2 are formed in a semi-elliptical shape, the knob portion 2 is kept in a lying state by its resistance. Therefore, even when a plurality of pan lids B are stacked and stored, the knob portion 2 does not become an obstacle, and stable storage is possible in a small space. Further, even when the pan lid B is stood vertically and stored, the knob portion 2 is kept in the sleeping state, so that stable storage in a small space is possible as described above.

In the transition from the standing state (during cooking) of the knob part 2 to the sleeping state (during storage), as shown in FIG. 8, when the knob part 2 is tilted by a user, the shaft 3 is moved to the bearing. Move in 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 inclined. When the long-axis tip 2b is in contact with each other, the distance d between the two axes is maximum (FIG. 4B), and the distance d is minimum during cooking and storage. The shaft 3 moves in the outward direction, and at the same time is pulled inward by a coil spring that is the biasing 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. For this reason, the knob portion 2 is not stable in an intermediate region other than during cooking and storage, and the state is stably maintained only during cooking or storage.

According to the pan lid knob 100, the following effects are exhibited. When the pan lid B is used (during cooking), the knob portion 2 is kept upright and the knob portion 2 cannot be tilted against the user's will, so the pan lid B can be used safely. it can. On the other hand, when the pan lid B is stored, the knob portion 2 is kept in the sleeping state. Therefore, even when a plurality of pan 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 pan lid B is stood vertically and stored, the knob portion 2 is kept in the sleeping state, so that stable storage is possible in a small space. The knob portion 2 is not stable in an intermediate region other than during cooking and storage, and the state is stably maintained only during cooking or storage. The state of the part 2 can be switched.

Further, since the tip portion 2d of the knob portion 2 is flattened, when the knob portion 2 shifts from a standing state to a sleeping state, the tip portions 2d support each other on the surface, whereby the knob portion 2 can firmly hold the sleeping state. In addition, since the knob portion 2 is configured in an arch shape, a space for the user to pick the knob portion 2 can be secured in the standing state and the sleeping state of the knob portion 2. Improved operability.

FIG. 20 is a conceptual diagram showing the movement of each part accompanying the movement of the knob part of the fourth embodiment. Since the configuration of the pan lid knob 400 is the same as that of the second or third embodiment except the later-described knob portion 402 and stand portion 408, the description thereof will be omitted, and the same components are denoted by the same reference numerals. .

The knob portion 402 is a pair of left and right symmetrical semi-circular plate-like bodies, and both end portions 402a are semi-elliptical in side view. 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 disposed on the upper portion of the main body 201. The knob portion 402 includes a plurality of attachment holes 402c for attaching the stand portion 408. The semi-elliptical long-axis tip 402b is obliquely downward on the side where the knobs 402 are in contact with each other when the knob 402 is standing, and is obliquely upward on the side where they are in contact with each other when the knob 402 is 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 natural resin or synthetic resin. In the case of synthetic resin, it is preferable to use, for example, phenol resin or silicone rubber.

The knob portion 402 can adopt a semi-elliptical shape or a polygonal shape in addition to a semi-annular shape. The long shaft tip 402b is formed in a gear shape or a cam shape in the vicinity of the tip. It is preferable to make the vicinity of the tip gear-like because the knob portions 402 can be interlocked with each other more reliably.

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

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

FIG. 22 is a cross-sectional view showing an example of attachment of the stand portion 408 of the fourth embodiment to the knob portion 402. The stand portions 408 are attached to the knob portion 402 one by one, and are 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 the convex portion 408a and the concave portion 408b being inserted through and fitted into 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 stands up (during cooking) and the state in which the knob portion 402 lies down (during storage) are the same as in the second or third embodiment, and thus description thereof is omitted.

In the transition from the standing state (during cooking) to the sleeping state (during storage) of the knob part 402, as shown in FIG. 20, when the knob part 402 is tilted by the user, the shaft 203 is moved to the bearing. It moves in 205 (FIG. 20 (d)). That is, since both end portions 402a of the knob portion are formed in a semi-elliptical shape, the knob portion 402 and the shaft 203 move outward in a side view as the knob portion 402 is inclined. At this time, the distance d between the two axes of the shaft 203 is maximized, and the pressing force of the leaf spring as the biasing 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 tips 402b come into contact with each other (FIG. 20 (c)). At this time, since the vicinity of the long end 402b is flattened with a predetermined width, the distance d between the two axes of the shaft 203 is minimized, and the pressing force of the leaf spring as the biasing means 204 is also minimized. Become. Therefore, the knob portion 402 is kept in a stable state. In this state, the user can make the pan lid B self-supporting by using the stand portion 408. That is, the pot lid B is self-supporting by being supported by a total of three points, one edge of the pot lid B and one point of the stand portion 408.

When the knob portion 402 is further tilted by the user, the shaft 203 moves again in the bearing 205 (FIG. 20B). As described above, the distance d between the two axes of the shaft 203 is maximized, and the pressing force of the leaf spring as the urging means 204 is also maximized, so that the knob portion 402 is in an unstable state even in this intermediate region. It becomes. When the knob portion 402 is further tilted by the user, the knob portion 402 is in a sleeping state (during storage) and is stably maintained.

According to the pan lid knob 400, in addition to the same effects as those of the second and third embodiments, the pan lid B can be made independent. Therefore, the space occupied by the pan lid B when the pan lid B is temporarily removed from the pan during cooking can be minimized. Moreover, it can dry efficiently and hygienically by making the pot lid B after washing | cleaning become independent.

As mentioned above, although embodiment which concerns on this invention was described, this invention is not limited to this. For example, in the above-described embodiment, it has been described that the shaft 203 protrudes from the both end portions 202a to the left and right sides in front view, but either the left or right, that is, either the outer peripheral side or the center side of the main body 201. It is good also as a structure which protrudes.

In the above embodiment, it has been described that the shafts 3 and 203 are provided at substantially the center of both end portions of the knob portions 2, 202 and 402. However, the shafts 3 and 203 may be provided eccentrically. That is, by arranging the shafts 3 and 203 eccentrically from the centers of both end portions of the knob portions 2, 202 and 402 so that the biasing force (tension or pressing force) of the biasing means is increased in the intermediate region, By increasing the urging force, the knob portions 2, 202 and 402 in the intermediate region become more unstable, so that the pan lid knob can be operated more quickly.

Moreover, although the said pan lid knob 400 was demonstrated based on Embodiment 2, a combination is not restricted to this. That is, it may be based on the first or third embodiment. In this case, the effects of the first or third embodiment are also produced at the same time.

Further, as shown in FIG. 23, it is possible to provide design features such as various patterns on the main body, the knob part, the stand part, etc., or the shape resembling a lemon or clover leaf. By doing this, it becomes possible to change the knob of the pan lid with the same feeling as selecting a dish according to mood, food, and serving place, and it becomes possible to respond to various demands.
