[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
1. Overall Configuration FIG. 1 shows a front view of a pan with a lid according to the present invention housed in a heater. Here, in particular, FIG. 1A shows a state in which the lid of the pot with a lid is open, and FIG. 1B shows a state in which the lid is closed.
[0009]
When the pot 1 with the lid is stored in the heater 3, the entire pot except for the upper part of the pot 1 with the lid is covered by the heater 3. Under such a condition, the pot 1 with the lid is heated by the heat source 5 provided at the bottom of the heater 3.
[0010]
When the lid 11 is closed, the lid 11 forms a small gap with the pot 21 inside the opening 15 of the metal pot 21, that is, further inside the upper edge 23 of the pot 21. The opening 15 of the pan 21 is almost completely closed (it is well shown in FIGS. 4 and 5 described later). Note that the lid 11 only needs to be heat-resistant, and is not limited to metal, and may be, for example, transparent glass. In order to keep the lid 11 closed, a concave locking portion 17 is provided on the upper edge of the lid 11, and a convex locking portion 19 is provided on the upper edge of the pan 21 correspondingly. . The convex locking portion 19 and the concave locking portion 17 can be elastically deformed to each other to some extent. When the lid 11 is closed, the projection 20 of the convex locking portion 19 on the pot side has the concave shape on the lid side. It snaps into the recess 18 (shown well in FIG. 2) of the locking part 17 by elasticity. Thereby, the lid 11 can be maintained in a closed state. Conversely, in order to open the closed lid 11, the lid 11 is pulled up while applying a force to the concave locking part 17 on the lid side in a direction to pull it away from the convex locking part 19 on the pot side (right direction in FIG. 1). Just do it.
[0011]
2. FIG. 2 is an external perspective view of a pot with a lid according to the present invention. The lid 11 and the pan 21 are respectively provided with a lid-side mounting member 31 and a pan-side mounting member 41 provided corresponding to the lid-side mounting member 31 at one side edge thereof. , 41 allow the lid 11 to be removably attached to the pan 21. The lid-side mounting member 31 and the pan-side mounting member 41 are provided in two sets near the center of one side edge thereof.
[0012]
The pan-side mounting member 41 has a slit 27 formed at the upper edge 23 of the pan so as to communicate with the outer wall 25 of the pan, and a fixing bracket 29 attached to the outer wall of the pan so as to be aligned with the slit 27. Consists of The lid 11 can be removably attached to the pan 21 by inserting and removing a part of the lid-side attachment member 31 in the gap formed by the slit 27 and the fixture 29 in the direction indicated by the arrow A in the drawing. The cover-side attachment member 31 may be provided with a cover 51 for protecting the cover-side attachment member 31.
[0013]
<Lid-side mounting member>
FIG. 3 shows a perspective view of the lid-side mounting member 31. FIG. The lid-side attachment member 31 includes a first hinge portion 33 completely fixed to the lid side, a second hinge portion 35 detachably attached to the pan side, and a first hinge portion 33 and a second hinge portion 35. It comprises a shaft pin 37 that is rotatably connected to each other, and a coil spring 39 provided around the shaft pin 37 to urge the first hinge portion 33 and the second hinge portion 35 in a predetermined direction. In the present invention, since the lid-side attachment member 31 is completely fixed to the lid 11, handling of the lid 11 is very easy.
[0014]
Each of the first hinge portion 33 and the second hinge portion 35 has a substantially L-shape as a whole when viewed from the lateral direction, and includes first right-angled portions 33a, 35a and a second right-angled portion 33b substantially orthogonal to each other. , 35b. Here, the first right angle portion 33 a of the first hinge portion 33 is a portion fixed to the lid 11. The lid 11 is fixed to the first hinge portion 33 so as to be rotatably supported by the second hinge portion 35, more specifically, the pan 21. In order to fix the lid 11, two holes 32 for passing screws 28 (shown in FIG. 7) used when fixing the lid 11 are provided in the first right angle portion 33a of the first hinge portion 33. Have been. The first right-angled portion 35a of the second hinge portion 35 is a portion that is inserted into and removed from the gap (27, 29) of the pan-side mounting member 41. Side walls 34 and 36 are formed on the left and right side surfaces of the remaining second right angle portion 33b of the first hinge portion 33 and the second right angle portion 35b of the second hinge portion 35, respectively, and are provided on these side walls 34 and 36, respectively. The first hinge portion 33 and the second hinge portion 35 can be connected to each other by passing the shaft pin 37 around which the coil spring 39 is wound through the hole provided.
[0015]
As can be inferred from FIG. 2, when the second hinge portion 35 is attached to the pan 21, the second right angle portion 35b of the second hinge portion 35 and the first hinge portion rotatably attached to the tip thereof. 33 can protrude toward the opening 15 of the pan 21. As a result, the lid 11 is rotatably supported above the opening 15 of the pan 21 at the protruding portion. At this time, the hole 30 provided near the center of the second right-angled portion 35b of the second hinge portion 35, that is, the steam release hole 30 is positioned above the opening 15 of the pan 21 where steam will just rise. Accordingly, by providing such a steam release hole 30, the steam generated from the pan 21 can be effectively released upward without collecting in the hinge portion. As described above, the lid 11 moves (rotates) together with the first hinge portion 33, whereas the second hinge portion 35 is attached to the pan 21 and does not move. Will be opened and closed in response to the
[0016]
4A is a sectional view taken along line 4a-4a in FIG. 3, and FIG. 4B is a sectional view taken along line 4b-4b in FIG. However, these drawings are different from FIG. 3 in which only the lid-side attachment member 31 is shown, in which the lid 11 is attached to the pan 21 by the lid-side attachment member 31 and the opening of the pan 21 is a lid. 11 is an enlarged view of a part of the vicinity of the lid-side mounting member, showing a state of being completely closed by 11 (however, the pan-side mounting member 41 is omitted).
[0017]
As is clear from these figures, the lid 11 is fixed to the lid-side mounting member 31 via the spacer 24, particularly the first right-angled portion 33a of the first hinge portion 33, on the upper surface thereof. When the opening of the pot 21 is completely closed, a slight gap 26 is formed between the edge 12 forming one side edge of the lid 11 and the inner wall 22 of the pot 21. Clearly, the gap 26 formed between the lid 11 and the pan 21 helps to prevent the internal pressure of the pan from becoming excessive during heating.
[0018]
Continuing to refer to FIG. 4, each end of the coil spring 39 contacts the protrusion 38 (also shown in FIG. 3) of the second hinge portion 35 on the side shown in FIG. In the state shown in FIG. 3B, a force is applied in the direction of the arrow B shown in FIG. It can be seen that the state is such that a force is applied in the direction of C. As a result, as shown in at least FIG. 4, when the first right angle portion 35 a of the second hinge portion 35 and the first right angle portion 33 a of the first hinge portion 33 form approximately 90 degrees. Due to the action of the coil spring 39, the first right-angled portion 35a of the second hinge portion 35 exerts a force in the direction of the arrow B 'shown, while the first right-angled portion 33a of the first hinge portion 33 exerts a force in the direction of the arrow C' shown. Will receive it. The function of the coil spring 39 serves to constantly urge the first hinge portion 33 and the second hinge portion 35 in the direction in which the lid 11 is opened. It helps to prevent it from closing and also helps to reduce the impact of closing the lid when closing it. Although it is not clear from the drawing, the coil spring 39 adjusts the angle A between the first right angle portion 33a of the first hinge portion 33 and the first right angle portion 35a of the second hinge portion 35 until, for example, about 260 degrees. Let's say it's like adding some force to them.
[0019]
3. Cover and its peripheral members FIG. 5 is a partially enlarged perspective view showing a state where the cover-side mounting member is covered with the cover, and FIG. 6 is a sectional view taken along line 6-6 of FIG. . On the other hand, FIG. 7 is a view showing a state in which the cover is removed from the lid-side mounting member in the same manner as in FIG. 5, and FIG. 8 is a view showing a cross section of this FIG. 7 in the same manner as in FIG. is there.
[0020]
In order to protect the lid-side mounting member 31, the present invention uses a cover 51 provided separately from the lid-side mounting member 31. The cover 51 can be detachably attached to the lid 11 so as to cover a part of the lid-side attachment member 31.
[0021]
In order to attach the cover 51 to the lid 11, a cover receiver 53 is fixedly provided at an upper portion of the lid 11 in the vicinity of the lid-side mounting member 31, for example, at a position where the lid 51 is sandwiched from both sides by the two lid-side mounting members 31. ing. 6 and 8, the cross section of the cover receiver 53 is substantially T-shaped.
[0022]
Corresponding to the cross-sectional shape of the cover receiver 53, two inner projections 55a and 55b are provided on the inside of the cover 51 so as to be elastically displaceable over a predetermined width near the center thereof. Although not clear from the drawing, the length of the width of the inward projection corresponds to the length of the width of the projecting portion 54 of the cover receiver 53 (shown well in FIG. 7). It may be considered that the length is substantially the same as the width of the projecting portion 54 of the receiver 53.
[0023]
In order to attach the cover 51 to the lid 11, the cover 51 may be covered from above the cover receiver 53 and a force may be applied toward the lid. At this time, the two inward projections 55 a and 55 b of the cover 51 get over the projecting portion 54 of the cover receiver 53 while being elastically displaced outward, and snap fit between the cover receiver 53 and the lid 11. Therefore, in the present invention, the cover 51 can be attached with one touch. When the cover 51 is completely attached to the cover receiver 53, the cover 51 is provided with substantially the entirety of the first hinge portion 33 of the lid-side attachment member 31 and the second right-angled portion 35b of the second hinge portion 35 (except for the steam escape). (Except near the hole 30). In such a state, the cover 51 is located at a position closer to the distal end portion 56 of one of the inner protrusions 55a forming the outer wall of the cover 51 and the other inner protrusion 55b as viewed from the one inner protrusion 55a. The cover 11 contacts the lid 11 only at a distant point, that is, the support portion 57 forming the outer wall of the cover 51, and the other inward projection 55 b does not contact the cover 11. Such a positional relationship is useful when removing the cover 51 as described later.
[0024]
Conversely, to remove the attached cover 51 from the lid 11, the cover 51 may be lifted upward such that the inward projection of the cover 51 is displaced outward. To facilitate the work, a handle 58 is provided on the outer wall on the opposite side of the one inner protrusion 55a. In other words, when removing the cover 51 from the lid 11, the vicinity of the handle 58 can be a point of emphasis. As is apparent from the above description, in the present invention, the distance from the handle 58, which can be the point of emphasis, to the support portion 57 is larger than the distance from the handle 58 to the other inward projection 55b. (Inward projection) of the cover 11 can be removed from the lid 11 with a small force by using the principle of leverage by applying a force in a direction of pulling away from the lid 11 (a direction shown by an arrow D in the drawing). In other words, according to the present invention, the cover 51 can be easily removed by removing the cover 51 with a single touch, for example, dust accumulated inside the cover 51. It is preferable that the inner projection 55a to which a force is directly applied is formed slightly larger than the other inner projection 55b so that the cover 51 can be removed more smoothly.
[0025]
The four notches 59 provided on the cover 51 are provided to avoid collision with the side wall 36 provided on the second right-angled portion 35b of the second hinge portion 35. Obviously, the size of these cutouts 59 is such that when the lid 11 is opened (even when the first hinge part 33 is rotated), their collision with the side wall 36 is avoided. It must be sufficient, but on the other hand, in order to prevent the steam from the pot 21 from entering the inside of the hinge portion as much as possible, the steam is set to such an extent that steam does not enter. These notches 59 also serve to facilitate attachment and detachment to the lid-side attachment member. This is because the provision of these notches 59 enhances the elasticity of the inner projection 55a. That is, the inner protrusion 55a can be moved with less force than when there is no notch. The lower portions of the left and right portions 60a and 60b, which are sandwiched between the cutouts 59a and 59b, are shorter than the other portions so as not to block the steam release holes 30. It is preferable that the extent to which these are shortened be reduced to a necessary and sufficient extent as in the above case.
[0026]
The operation of the cover 51 will be described in more detail with reference to FIGS. 5 to 8 in conjunction with FIG. As is apparent from these figures, regardless of whether the lid 11 is opened or closed, the cover 51 does not cover the steam release hole 30 even when the cover 51 is attached to the lid-side attachment member 31. When the lid 11 is open as shown in FIG. 7, the inclined portion 42 of the cover 51 provided with the notch 59 (see FIGS. 5 to 8) is positioned beside the steam release hole 30 so as to avoid the steam release hole 30. On the other hand, the inclined portion 43 (shown well in FIGS. 5 to 8) of the cover 51 without the notch 59 is positioned at the lateral position above the steam release hole 30. As a result, the steam from the steam escape hole 30 does not directly flow into the notch 59 of the cover 51, and the invasion of the steam into the cover 51 can be effectively prevented. Note that the inclined portion 43 of the cover 51 positioned at a lateral position above the steam release hole 30 is provided in a substantially vertical direction when the lid 11 is opened so that the steam from the steam release hole 30 escapes upward more effectively. It is preferable to be inclined so as to move toward.
[0027]
4. In the above embodiments, the cover 51 is provided on the lid-side mounting member 31. However, the cover 51 may be provided on the pan-side mounting member 41. Moreover, it is good also as providing in both of them. Such modifications would be readily apparent to one skilled in the art. The present invention includes all such modifications.
[0028]
【The invention's effect】
According to the present invention, it is possible to provide a pot with a lid that can be easily attached and detached. In addition, by providing a cover that can be easily detached and attached to such an attachment member of the lid with a lid, a more hygienic lid with a lid can be provided.
