Abstract
Description
[Technical Field]
[0001] The present invention relates to a trivet that is placed on a top plate that covers the top surface of a cooking appliance, and more particularly to a technique for preventing detachment of a cushioning member attached to the trivet. [Background technology]
[0002] A commonly known structure for cooking appliances such as gas stoves is one in which a top plate is installed to cover the top surface and a heating element such as a stove burner protrudes upward from an opening in the top plate. A trivet for placing a cooking vessel such as a pot on the top plate is also placed on the top plate and is removable above the heating element. The trivet has a trivet frame that surrounds the heating element and a plurality of trivet claws that are supported by the trivet frame and extend above the heating element. The cooking vessel is supported by the trivet claws and heated from below by the heating element.
[0003] These trivets are generally made of metal, and if they come into contact with a tabletop made of glass or the like, they can scratch the tabletop. Therefore, it has been proposed to attach a buffer member made of an elastic material such as rubber to the trivet (Patent Document 1). By having multiple buffer members attached to the bottom of the trivet from below come into contact with the tabletop, the trivet frame and trivet claws do not come into contact with the tabletop, preventing the trivet from scratching the tabletop. [Prior art documents] [Patent documents]
[0004] [Patent Document 1] Japanese Patent Application Publication No. 2017-020756 Summary of the Invention [Problem to be solved by the invention]
[0005] However, with a trivet equipped with a buffer member as described above, if, for example, water boils over from a cooking container placed on the trivet and drips onto the top plate, the spilled liquid can cause the trivet's buffer member to adhere to the top plate. In this state, if the trivet is lifted to remove it, the buffer member can come off the trivet, creating a problem.
[0006] This invention has been made in response to the above-mentioned problems in the conventional technology, and aims to provide a technology that can prevent the buffer member from coming off the trivet when the trivet is lifted while the buffer member is fixed to the top plate. [Means for solving the problem]
[0007] In order to solve the above-mentioned problems, the trivet of the present invention adopts the following configuration. A trivet is detachably placed on a top plate covering the top surface of a cooking appliance, and a cooking vessel is placed above a heating portion protruding from an opening in the top plate, A trivet frame surrounding the heating unit; A plurality of trivet claws supported by the trivet frame and extending upward toward the heating unit; a plurality of cushioning members formed of an elastic material and having contact portions that contact the top plate; a plurality of attachment portions to which the buffer members are attached; Equipped with When the contact portion of the buffer member attached to the attachment portion is in contact with the top plate, the trivet frame and the trivet claws are not in contact with the top plate, The mounting direction of the buffer member to the mounting portion intersects with the mounting direction of the trivet to the top plate, The contact portion is provided at a position different from the rear end of the buffer member in the mounting direction. It is characterized by:
[0008] According to this trivet of the present invention, when the trivet is placed on the tabletop, the contact portion of the cushioning member abuts against the tabletop, so that the trivet frame and trivet claws are floating without abutting against the tabletop, preventing scratches on the tabletop caused by contact between the trivet frame and trivet claws. Furthermore, if the cushioning member is fixed to the tabletop, and the mounting direction of the cushioning member and the trivet removal direction are parallel, the force applied to lift the trivet to remove it acts directly in the direction of removal of the cushioning member, causing the cushioning member to come off the trivet. On the other hand, if the mounting direction of the cushioning member and the mounting direction of the trivet are intersecting, the force acting in the direction of removal of the cushioning member is smaller than when they are parallel. In particular, if they are perpendicular, the force applied to lift the trivet does not act in the direction of removal of the cushioning member, preventing the cushioning member from coming off the trivet.
[0009] The trivet of the present invention described above may be configured as follows. First, the mounting portion is a plate-shaped member that is substantially perpendicular to the trivet frame, and the plate-shaped member has a recess cut from the side edge facing the buffer member in the mounting direction. The buffer member has a protrusion that is inserted into the recess when mounted to the plate-shaped member, and a pair of side walls that sandwich the plate-shaped member from both sides in the thickness direction. Furthermore, the recess has a narrowed portion on the side facing the buffer member that is smaller in dimension perpendicular to the mounting direction, and the protrusion has an expanded portion on the side facing the plate-shaped member that is larger in dimension perpendicular to the mounting direction. The narrowed portion and the expanded portion engage when the protrusion is press-fitted into the recess.
[0010] In this way, when the convex portion is pressed into the concave portion, the narrowed portion and the expanded portion engage with each other, preventing the buffer member from coming off. This makes it possible to make the buffer member even more difficult to come off the trivet, while still using a simpler configuration than when it is fixed with screws or the like.
[0011] The trivet of the present invention may also be configured as follows. First, the mounting portion is a plate-shaped member that is substantially perpendicular to the trivet frame, and the plate-shaped member has a convex portion that protrudes from the side edge facing the buffer member in the mounting direction. The buffer member has a concave portion into which the convex portion is inserted when mounted to the plate-shaped member, and a pair of side walls that sandwich the convex portion from both sides in the thickness direction of the plate-shaped member. Furthermore, the convex portion has an expanded portion on the side facing the buffer member that is larger in the dimension perpendicular to the mounting direction, and the concave portion has a narrowed portion on the side facing the plate-shaped member that is smaller in the dimension perpendicular to the mounting direction. Then, the expanded portion and the narrowed portion engage when the convex portion is press-fitted into the concave portion.
[0012] In this way, when the convex portion is pressed into the concave portion, the expansion portion and the narrow portion engage with each other to prevent the buffer member from coming off. This makes it possible to make the buffer member even more difficult to come off the trivet, while still using a simpler configuration than when it is fixed with screws or the like.
[0013] The trivet claws of the trivet of the present invention may be plate-shaped members that are perpendicular to the trivet frame, and a mounting portion may be provided at the bottom of the trivet claws.
[0014] In this way, by reusing the existing trivet claws, it is not necessary to add a new dedicated part, and it is possible to attach the buffer member without making major changes to the overall design of the trivet.
[0015] The attachment portion of the trivet of the present invention described above may be provided on the side facing the heating portion at the bottom of the trivet claw.
[0016] In this way, the trivet claws extending upward from the heating section are positioned to protect the upper part of the buffer member when attached to the attachment section, thereby preventing problems such as the buffer member being damaged or coming off due to contact with a cooking container or the like.
[0017] The trivet of the present invention described above may be mounted on a cooking appliance, and a cooking container placed on the trivet may be heated by the heating section.
[0018] In such a cooking device, the buffer material is used to prevent the trivet from scratching the top plate, and when the trivet is lifted while the buffer material is fixed to the top plate, it is possible to prevent the buffer material from coming off the trivet.

[0020] 1 is a perspective view showing the upper appearance of a gas stove 1 as an example of a cooking appliance according to this embodiment. The gas stove 1 has a top plate 2 installed to cover the top surface of a stove body (not shown), and the top of a stove burner 3 mounted on the stove body protrudes from an opening (not shown) formed in the top plate 2. In the example shown, an annular burner ring 4 is installed on the top plate 2, covering the gap between the periphery of the opening in the top plate 2 and the stove burner 3, and the top of the stove burner 3 is inserted into an insertion hole 4a inside the burner ring 4. The stove burner 3 in this embodiment corresponds to the "heating unit" of the present invention.
[0021] Additionally, a trivet 10 for placing cooking vessels such as pots is placed on the top plate 2 above the stove burner 3 and is removable. The trivet 10 has a trivet frame 11, which is a frame that surrounds the stove burner 3, and multiple trivet claws 12 (seven in the illustrated example) that are supported by the trivet frame 11 and extend above the stove burner 3. The cooking vessels are supported by the multiple trivet claws 12 and are heated by the stove burner 3 from below.
[0022] The trivet frame 11 shown in the figure is formed by bending a steel strip into a substantially rectangular shape. Correspondingly, the trivet claws 12 are not uniform in shape because the distance and orientation to the burner 3 vary depending on the joint position with the trivet frame 11. However, they basically have a vertical side 12a erected substantially perpendicular to the trivet frame 11, and an upper side 12b extending substantially horizontally from the top of the vertical side 12a toward the burner 3 and contacting the bottom surface of the cooking vessel.
[0023] The trivet claw 12 is generally U-shaped and includes a lower side 12c extending from the lower part of the vertical side 12a along the top plate 2 toward the stove burner 3, and the tip of the lower side 12c fits into a recess 4b formed on the outer periphery of the burner ring 4. The burner ring 4 is positioned and prevented from rotating on the bottom side relative to the top plate 2, so that the tip of the lower side 12c engages with the recess 4b of the burner ring 4, thereby positioning the trivet 10 relative to the burner ring 4 and preventing it from rotating.
[0024] Such trivets 10 are generally made of metal because the trivet claws 12 are heated by the flames of the stove burner 3. On the other hand, the top plate 2 on which the trivet 10 is placed is generally made of glass, which is easy to clean and has an aesthetically pleasing appearance, and the trivet 10 may scratch the top plate 2 when it comes into contact with the trivet 10. In the gas stove 1 of this embodiment, in order to prevent the trivet 10 from scratching the top plate 2, multiple cushioning members 20 made of an elastic material such as silicone rubber are attached to the trivet 10.
[0025] In the example shown in Figure 1, buffer members 20 are attached to the lower parts of the vertical side parts 12a of the four trivet claws 12 that do not have the bottom side part 12c. As will be described later, the buffer members 20 have abutment parts that abut against the top plate 2 when the trivet 10 is placed on the top plate 2, and as the abutment parts of the multiple buffer members 20 abut against the top plate 2, the trivet frame 11 and trivet claws 12 are not in contact with the top plate 2 and are floating. The lower parts of the vertical side parts 12a in this embodiment correspond to the "attached part" of the present invention.
[0026] In a trivet 10 equipped with such a buffer member 20, for example, if water boils over from a cooking container placed on the trivet 10 and drips onto the top plate 2, and if the water is left as is, the buffer member 20 may become stuck to the top plate 2. When the trivet 10 is lifted up to remove it in this state, it is expected that the buffer member 20 will become detached from the trivet 10. Therefore, the gas stove 1 of this embodiment employs the following configuration to prevent the buffer member 20 from becoming detached from the trivet 10 when the trivet 10 is lifted up with the buffer member 20 of the trivet 10 fixed to the top plate 2.
[0027] FIG. 2 is an explanatory diagram showing the mounting configuration of the buffer member 20 in the trivet 10 of the first embodiment. First, FIG. 2(a) is a perspective view showing the state before the buffer member 20 is mounted on the trivet 10. The dashed arrow in the figure indicates the mounting direction of the buffer member 20. In the trivet 10 of the first embodiment, the buffer member 20 is mounted approximately horizontally to the lower part of the vertical side portion 12a of the trivet claw 12. The trivet claw 12 is a plate-shaped member formed of stainless steel plate or the like, and the vertical side portion 12a is erected approximately perpendicular to the trivet frame 11. The vertical side portion 12a to which the buffer member 20 is mounted has a recess 13 cut out in the approximately horizontal direction (mounting direction) from the side edge on the inner side (the side from which the upper side portion 12b extends) facing the stove burner 3 in the width direction.
[0028] On the other hand, the cushioning member 20 has a pair of side walls 20a that sandwich the vertical side portion 12a from both sides in the thickness direction when attached to the vertical side portion 12a, and a protrusion 21 that is inserted into the recess 13 is provided between the pair of side walls 20a. Note that the cushioning member 20 in the first embodiment is made of silicone rubber, but since it is attached to the trivet claws 12, it is desirable that the material be one that is not only elastic but also heat-resistant.
[0029] 2(b) shows the state before the buffer member 20 is attached to the trivet 10, in a cross-sectional view taken along a plane parallel to the vertical side 12a of the trivet claw 12. As shown in the figure, the recess 13 of the vertical side 12a has a narrowed portion 13a on the side facing the buffer member 20, which reduces the vertical dimension perpendicular to the attachment direction, and is formed in a horizontal, approximately T-shape.
[0030] The cushioning member 20 has a protrusion 21 that protrudes from a rear end 20b located at the rear end in the installation direction toward the front end. This protrusion 21 has an extended portion 21a on the side facing the vertical side 12a that has an increased vertical dimension perpendicular to the installation direction, and is formed into a horizontal, approximately T-shape that corresponds to the recess 13 of the vertical side 12a. In addition, the cushioning member 20 has an abutment portion 20c that abuts against the top plate 2 and extends from the lower end of the rear end 20b in the installation direction. This abutment portion 20c is located below the protrusion 21 and forms the bottom surface of the cushioning member 20.
[0031] When attaching the buffer member 20 to the trivet 10, the convex portion 21 of the buffer member 20 is press-fit into the concave portion 13 of the vertical side portion 12a. The expanding portion 21a of the convex portion 21 has a vertical dimension larger than the narrow portion 13a of the concave portion 13, so the expanding portion 21a deforms as it enters the narrow portion 13a. Once the expanding portion 21a passes through the narrow portion 13a, it elastically returns to its original shape, and as shown in Figure 2(c), the narrow portion 13a and the expanding portion 21a engage with each other, preventing the buffer member 20 from coming loose.
[0032] With the buffer member 20 attached to the trivet 10 in this way, the contact portion 20c of the buffer member 20 is located lower than the trivet frame 11 and the trivet claws 12, so when the trivet 10 is placed on the tabletop 2 and the contact portion 20c of the buffer member 20 comes into contact with the tabletop 2, the trivet frame 11 and the trivet claws 12 are floating and do not come into contact with the tabletop 2. As a result, scratches on the tabletop 2 caused by contact with the trivet frame 11 and the trivet claws 12 can be prevented.
[0033] In the trivet 10 of the first embodiment, the attachment direction of the buffer member 20 to the vertical side portion 12a of the trivet claw 12 is not parallel to, but intersects (substantially perpendicular to) the up-down direction, which is the direction in which the trivet 10 is attached to and detached from the tabletop 2. Accordingly, the structure of the buffer member 20 has a contact portion 20c provided at a position different from the rear end portion 20b. As a result, even if an attempt is made to lift the trivet 10 upward with the contact portion 20c of the buffer member 20 fixed to the tabletop 2, the direction of the lifting force and the direction in which the buffer member 20 is detached are not parallel, and in the first embodiment in particular are substantially perpendicular, so that the upward force used to lift the trivet 10 does not act in the direction in which the buffer member 20 is detached, preventing the buffer member 20 from coming off the trivet 10.
[0034] Furthermore, in the trivet 10 of the first embodiment, the convex portion 21 of the buffer member 20 is press-fit into the concave portion 13 of the vertical side portion 12a, so that the narrowed portion 13a of the concave portion 13 and the expanded portion 21a of the convex portion 21 engage with each other, and the buffer member 20 is prevented from coming off despite the simpler configuration compared to when it is fixed with screws or the like, making it even more difficult for the buffer member 20 to come off the trivet 10.
[0035] Furthermore, in the trivet 10 of the first embodiment, a buffer member 20 is attached to the inside of the vertical side portion 12a of the trivet claw 12, facing the stove burner 3 in the width direction (see Figure 2(a)), and since the upper side of the buffer member 20 when attached is protected by the upper side portion 12b of the trivet claw 12, problems such as the buffer member 20 being damaged or coming off due to contact with a cooking container or the like can be prevented.
[0036] 3 is an explanatory diagram showing the mounting configuration of the buffer member 20 in the trivet 10 of the second embodiment. First, FIG. 3(a) is a perspective view showing the state before the buffer member 20 is mounted on the trivet 10. As indicated by the dashed arrow in the figure, in the trivet 10 of the second embodiment, as in the first embodiment described above, the buffer member 20 is mounted in a substantially horizontal direction to the lower part of the vertical side portion 12a of the trivet claw 12. However, in the second embodiment, the vertical side portion 12a has a protrusion 14 that protrudes from the side end on the inner side (the side on which the upper side portion 12b extends) facing the stove burner 3 in the width direction, facing the mounting direction.
[0037] On the other hand, when the cushioning member 20 is attached to the vertical side portion 12a, it has a pair of side wall portions 20a that sandwich the convex portion 14 from both sides in the thickness direction of the vertical side portion 12a, and a recess 22 into which the convex portion 14 is inserted is provided between the pair of side wall portions 20a.
[0038] 3(b) shows the state before the buffer member 20 is attached to the trivet 10, in a cross-sectional view taken along a plane parallel to the vertical side 12a of the trivet claw 12. As shown in the figure, the protrusion 14 of the vertical side 12a has an extended portion 14a on the side facing the buffer member 20 that has an increased vertical dimension perpendicular to the attachment direction, forming a horizontally oriented, approximately T-shaped portion.
[0039] The cushioning member 20 has a recess 22 cut from the front end to the rear end in the mounting direction. This recess 22 has a narrowed portion 22a on the side facing the vertical side 12a, the narrowed portion 22a having a reduced vertical dimension perpendicular to the mounting direction, and is formed in a horizontal, approximately T-shape corresponding to the protrusion 14 of the vertical side 12a. In addition, the abutting portion 20c of the cushioning member 20 is located below the recess 22, and forms the bottom surface of the cushioning member 20.
[0040] When the buffer member 20 is attached to the trivet 10, the convex portion 14 of the vertical side portion 12a is press-fit into the concave portion 22 of the buffer member 20. The expanded portion 14a of the convex portion 14 has a vertical dimension larger than the narrowed portion 22a of the concave portion 22, so the narrowed portion 22a is deformed as the expanded portion 14a advances. Then, when the expanded portion 14a passes through the narrowed portion 22a, the narrowed portion 22a elastically returns to its original shape, and as shown in Figure 3(c), the expanded portion 14a and the narrowed portion 22a engage with each other, preventing the buffer member 20 from coming loose.
[0041] When the buffer member 20 is attached to the trivet 10 of the second embodiment in this manner, as in the first embodiment, the abutment portion 20c of the buffer member 20 is located below the trivet frame 11 and the trivet claws 12, and as the abutment portion 20c abuts against the tabletop 2, the trivet frame 11 and the trivet claws 12 do not abut against the tabletop 2, thereby preventing the trivet 10 from scratching the tabletop 2. Furthermore, even if an attempt is made to lift the trivet 10 upward with the abutment portion 20c of the buffer member 20 fixed to the tabletop 2, the direction of the lifting force and the direction in which the buffer member 20 is detached are not parallel but are approximately perpendicular in the second embodiment as well, so the upward force used to lift the trivet 10 does not act in the direction in which the buffer member 20 is detached, preventing the buffer member 20 from coming off the trivet 10.
[0042] Furthermore, in the trivet 10 of the second embodiment, the convex portion 14 of the vertical side portion 12a is press-fitted into the concave portion 22 of the buffer member 20, so that the narrowed portion 22a of the concave portion 22 engages with the expanded portion 14a of the convex portion 14, preventing the buffer member 20 from coming off. This makes it possible to make the buffer member 20 even more difficult to come off from the trivet 10 with a relatively simple configuration.
[0043] Furthermore, in the trivet 10 of the second embodiment, as in the first embodiment, the upper part of the buffer member 20 attached to the inside of the vertical side portion 12a of the trivet claw 12 facing the stove burner 3 in the width direction is protected by the upper side portion 12b, thereby preventing the buffer member 20 from being damaged or coming off due to contact with a cooking container or the like.
[0044] FIG. 4 is an explanatory diagram showing the mounting configuration of the buffer member 20 in the trivet 10 of the third embodiment. First, FIG. 4(a) is a perspective view showing the state before the buffer member 20 is mounted on the trivet 10. In the first and second embodiments described above, the mounting direction of the buffer member 20 to the lower part of the vertical side portion 12a of the trivet claw 12 is the width direction of the vertical side portion 12a, whereas in the trivet 10 of the third embodiment, the mounting direction of the buffer member 20 to the lower part of the vertical side portion 12a of the trivet claw 12 is the thickness direction of the vertical side portion 12a. Corresponding to this, the vertical side portion 12a of the third embodiment has a through hole 15 that penetrates in the thickness direction.
[0045] On the other hand, when attached to the vertical side portion 12a, the buffer member 20 has a side wall portion 20a that contacts one side of the vertical side portion 12a in the thickness direction (the back side in the figure), and has a substantially cylindrical protrusion 23 that is inserted into the through hole 15 and protrudes substantially perpendicularly from the side wall portion 20a, with an expanded diameter portion 23a with an expanded outer diameter provided at the tip side of the protrusion 23. The buffer member 20 also has a groove-shaped bottom end groove 24a that fits the bottom end of the vertical side portion 12a, and a groove-shaped side end groove 24b that fits the inner side end of the vertical side portion 12a that faces the stove burner 3 in the width direction.
[0046] When attaching the buffer member 20 to the trivet 10, the protruding portion 23 of the buffer member 20 is inserted substantially horizontally into the through-hole 15 of the vertical side portion 12a, as indicated by the dashed-dotted arrow in the figure. Because the expanded diameter portion 23a of the protruding portion 23 has a larger diameter than the through-hole 15, the expanded diameter portion 23a is deformed by pressure as it enters the through-hole 15, and after passing through the through-hole 15, the expanded diameter portion 23a elastically returns to its original position. In addition, by bending the side wall portion 20a, the bottom end and side end of the vertical side portion 12a, which correspond to the bottom end groove 24a and side end groove 24b of the buffer member 20, fit into each other.
[0047] When the buffer member 20 is attached to the trivet 10 in this manner, as shown in Figure 4(b), the enlarged diameter portion 23a of the protrusion 23 engages with the periphery of the through-hole 15 in the vertical side portion 12a, preventing the buffer member 20 from slipping out. The bottom and side ends of the vertical side portion 12a fit into the bottom groove 24a and side groove 24b of the buffer member 20, preventing the buffer member 20 from rotating. Furthermore, the abutment portion 20c that forms the bottom surface of the buffer member 20 is located lower than the trivet frame 11 and the trivet claws 12. Therefore, when the abutment portion 20c abuts against the tabletop 2, the trivet frame 11 and the trivet claws 12 do not abut against the tabletop 2, preventing the trivet 10 from scratching the tabletop 2.
[0048] 4(c) shows the state in which the buffer member 20 is attached to the trivet 10, in an end view cut along a vertical plane perpendicular to the vertical side 12a. As in the first and second embodiments, the attachment direction of the buffer member 20 to the vertical side 12a of the trivet claw 12 intersects (substantially perpendicular to) the up-down direction, which is the direction in which the trivet 10 is attached to and detached from the tabletop 2, and the abutment portion 20c is provided at a position different from the side wall portion 20a, which is the rear end of the buffer member 20 in the attachment direction. As a result, even if an attempt is made to lift the trivet 10 upward with the abutment portion 20c of the buffer member 20 fixed to the tabletop 2, the direction of the lifting force and the direction in which the buffer member 20 is detached are not parallel but are substantially perpendicular in the third embodiment as well. Therefore, the upward force used to lift the trivet 10 does not act in the detachment direction of the buffer member 20, preventing the buffer member 20 from coming off the trivet 10.
[0049] Furthermore, in the trivet 10 of the third embodiment, the expanded diameter portion 23a of the protrusion 23 that passes through the through-hole 15 of the vertical side portion 12a engages with the periphery of the through-hole 15 to prevent the buffer member 20 from coming off, making it even more difficult for the buffer member 20 to come off the trivet 10. Additionally, in the trivet 10 of the third embodiment, as in the first and second embodiments, the upper side portion 12b protects the upper portion of the buffer member 20 attached to the inside of the vertical side portion 12a of the trivet claws 12 that faces the stove burner 3 in the width direction, thereby preventing the buffer member 20 from being damaged or coming off due to contact with a cooking vessel or the like.
[0050] In addition, in the trivet 10 of the third embodiment, a through hole 15 is provided in the vertical side portion 12a of the trivet claw 12, and an approximately cylindrical protrusion 23 with an enlarged diameter portion 23a is provided on the side wall portion 20a of the buffer member 20. However, conversely, it is also possible to provide an approximately cylindrical protrusion with an enlarged diameter portion on the vertical side portion 12a of the trivet claw 12, and to provide a through hole in the side wall portion 20a of the buffer member 20.
[0051] The trivet 10 of the various embodiments described above also has the following variations. Below, we will explain the variations, focusing on the differences from the various embodiments described above. In the explanation of the variations, the same components as those in the various embodiments described above will be assigned the same reference numerals and will not be explained again.
[0052] FIG. 5 is a perspective view showing the mounting configuration of the buffer member 20 in the trivet 10 of the first modified example. FIG. 5 shows the state before the buffer member 20 is mounted on the trivet 10. In the first embodiment described above, the trivet claws 12 are joined to the inside of the trivet frame 11, and a recess 13 is provided on the inner side edge (the side on which the upper side 12b extends) of the vertical side 12a, facing the burner 3 in the width direction (see FIG. 2(a)). In contrast, in the trivet 10 of the first modified example, the trivet claws 12 are joined to the outside of the trivet frame 11, and a recess 13 is provided on the outer side edge of the vertical side 12a, facing the burner 3 in the width direction. When the buffer member 20 is mounted on the trivet 10, the protrusion 21 provided between the pair of side walls 20a of the buffer member 20 is press-fit into the recess 13 of the vertical side 12a.
[0053] In this way, the trivet 10 of the first modified example, in which the buffer member 20 is attached to the outside of the vertical side 12a in the width direction, not facing the stove burner 3, can also obtain the effect of preventing the trivet 10 from scratching the top plate 2, and the effect of preventing the buffer member 20 from coming off the trivet 10 when the trivet 10 is lifted with the buffer member 20 fixed to the top plate 2, basically the same as the first embodiment described above, in which the buffer member 20 is attached to the inside of the vertical side 12a in the width direction, facing the stove burner 3. However, with the trivet 10 of the first modified example, it is not possible to obtain the effect of protecting the upper side of the buffer member 20 with the upper side 12b of the trivet claws 12.
[0054] Although the trivet 10 of the first modification has the same recess 13 as in the first embodiment provided on the vertical side 12a, it may have the same protrusion 14 as in the second embodiment provided on the vertical side 12a (see FIG. 3(a)), so that the protrusion 14 on the vertical side 12a is press-fitted into the recess 22 provided between the pair of side walls 20a of the cushioning member 20. Furthermore, it may have the same through-hole 15 as in the third embodiment provided on the vertical side 12a (see FIG. 4(a)), so that the protrusion 23 protruding from the side wall 20a of the cushioning member 20 is inserted into the through-hole 15 on the vertical side 12a.
[0055] Fig. 6 is a perspective view showing the mounting configuration of the buffer member 20 in the trivet 10 of the second modified example. Fig. 6 shows the state before the buffer member 20 is mounted on the trivet 10. In the first embodiment described above, the buffer member 20 was mounted on the lower part of the vertical side portion 12a of the trivet claw 12, which stands upright approximately perpendicular to the trivet frame 11. In contrast, in the trivet 10 of the second modified example, a mounting plate 16, which is a plate-like member separate from the trivet claw 12, stands upright approximately perpendicular to the trivet frame 11, and the buffer member 20 is mounted approximately horizontally to this mounting plate 16. The mounting plate 16 of the second modified example corresponds to the "mounted portion" of the present invention.
[0056] In this way, the trivet 10 of the second modified example, in which the buffer member 20 is attached to a mounting plate 16 separate from the trivet claws 12, can also obtain the effect of preventing the trivet 10 from scratching the tabletop 2, as well as the effect of preventing the buffer member 20 from coming off the trivet 10 when the trivet 10 is lifted with the buffer member 20 fixed to the tabletop 2, just like the first embodiment described above in which the buffer member 20 is attached to the trivet claws 12. However, if the existing trivet claws 12 are used to attach the buffer member 20 as in the first embodiment described above, there is no need to add a new member, and the buffer member 20 can be attached without significantly changing the overall design of the trivet 10.
[0057] 6, the mounting plate 16 is joined to the outside of the trivet frame 11, but the mounting plate 16 may also be joined to the inside of the trivet frame 11. Furthermore, the mounting plate 16 is provided with the same recess 13 as in the first embodiment, but the mounting plate 16 may also be provided with the same protrusion 14 as in the second embodiment or the same through hole 15 as in the third embodiment, and the corresponding buffer member 20 may be attached.
[0058] Fig. 7 is a perspective view showing the mounting configuration of the buffer member 20 in the trivet 10 of the third modified example. First, Fig. 7(a) shows the state before the buffer member 20 is mounted on the trivet 10. In the first embodiment described above, the buffer member 20 was mounted on the trivet claws 12. In contrast, in the trivet 10 of the third modified example, the buffer member 20 is mounted on the trivet frame 11.
[0059] In the illustrated example, a wide steel band is used for trivet frame 11, and it has through-holes 15 that penetrate through its thickness. When attached to trivet frame 11, buffer member 20 has a side wall 20a that contacts one side of trivet frame 11 in the thickness direction (the back side in the figure), and a substantially cylindrical protrusion 23 that is inserted into through-hole 15 protrudes substantially perpendicularly from side wall 20a, with an expanded diameter portion 23a with an expanded outer diameter provided at the tip of protrusion 23. Additionally, buffer member 20 is provided with a groove-shaped lower end groove 24a into which the lower end of trivet frame 11 fits.
[0060] When attaching the buffer member 20 to the trivet 10, the protruding portion 23 of the buffer member 20 is inserted substantially horizontally through the through-hole 15 of the trivet frame 11, as indicated by the dashed arrow in the figure. The expanded diameter portion 23a of the protruding portion 23 is larger in diameter than the through-hole 15, so that the expanded diameter portion 23a is deformed by pressure as it enters the through-hole 15, and after passing through the through-hole 15, the expanded diameter portion 23a returns elastically. Furthermore, by bending the side wall portion 20a, the lower end of the trivet frame 11 is fitted into the lower end groove 24a of the buffer member 20. The through-hole 15 of the trivet frame 11 of the third modified example corresponds to the "attached portion" of the present invention.
[0061] When the buffer member 20 is attached to the trivet 10 in this manner, as shown in Figure 7(b), the enlarged diameter portion 23a of the protrusion 23 engages with the periphery of the through-hole 15 of the trivet frame 11, preventing the buffer member 20 from coming loose. The lower end of the trivet frame 11 fits into the lower end groove 24a of the buffer member 20, preventing the buffer member 20 from rotating. Furthermore, because the abutment portion 20c that forms the bottom surface of the buffer member 20 is located lower than the trivet frame 11 and the trivet claws 12, when the abutment portion 20c abuts against the tabletop 2, the trivet frame 11 and the trivet claws 12 do not abut against the tabletop 2, preventing the trivet 10 from scratching the tabletop 2.
[0062] Furthermore, even if an attempt is made to lift the trivet 10 upward while the contact portion 20c of the buffer member 20 is fixed to the top plate 2, the direction of the lifting force and the direction in which the buffer member 20 is detached are not parallel, but are approximately perpendicular in the third variant, so the upward force used to lift the trivet 10 does not act in the direction in which the buffer member 20 is detached, preventing the buffer member 20 from coming off the trivet 10.
[0063] FIG. 8 is a perspective view showing the mounting configuration of the buffer member 20 in the trivet 10 of the fourth modified example. FIG. 8 shows a cross section cut along a plane parallel to the vertical side 12a of the trivet claw 12, illustrating the state before the buffer member 20 is mounted on the trivet 10. In the first embodiment described above, the trivet claw 12 is a plate-like member formed from a stainless steel plate or the like, and the recess 13 is formed as a notch. In contrast, in the trivet 10 of the fourth modified example, the trivet claw 12 is formed by casting (die-casting), so that a base 17 is secured below the vertical side 12a, and this base 17 has a recess 18 drilled into a substantially cylindrical shape. Furthermore, a reduced-diameter portion 18a with a reduced inner diameter is provided on the side of the recess 18 facing the buffer member 20.
[0064] On the other hand, the cushioning member 20 has a pair of side walls 20a (only one side is shown) that sandwich the base 17 when attached to the base 17, and a substantially cylindrical protrusion 25 that protrudes from a rear end 20b located at the rear end in the attachment direction toward the front end. An expanded diameter portion 25a with an expanded outer diameter is provided on the side of the protrusion 25 facing the base 17.
[0065] When the buffer member 20 is attached to the trivet 10, the convex portion 25 of the buffer member 20 is press-fit into the concave portion 18 of the base 17. Since the enlarged diameter portion 25a of the convex portion 25 has a larger diameter than the reduced diameter portion 18a of the concave portion 18, the enlarged diameter portion 25a deforms as it enters the reduced diameter portion 18a. After passing through the reduced diameter portion 18a, the enlarged diameter portion 25a elastically returns, and the reduced diameter portion 18a and the enlarged diameter portion 25a engage with each other, preventing the buffer member 20 from coming off. The base 17 of the fourth modified example corresponds to the "attached portion" of the present invention.
[0066] In this way, in the trivet 10 of the fourth variant, the approximately cylindrical expanded diameter portion 25a engages with the reduced diameter portion 18a around the entire circumference, thereby making it possible to improve the anti-removal performance of the buffer member 20 compared to the first embodiment described above, in which the expanded portion 21a of the horizontally facing, approximately T-shaped convex portion 21 engages with the narrowed portion 13a above and below.
[0067] In the fourth modified trivet 10, the base 17 of the trivet claw 12 is provided with an approximately cylindrical recess 18 having a reduced diameter portion 18a, and the buffer member 20 is provided with an approximately columnar protrusion 25 having an expanded diameter portion 25a. However, conversely, the base 17 of the trivet claw 12 may be provided with an approximately columnar protrusion with an expanded diameter portion, and the buffer member 20 may be provided with an approximately cylindrical recess with a reduced diameter portion.
[0068] 9 is a perspective view showing the mounting configuration of the buffer member 20 in the trivet 10 of the fifth modified example. In the above-described embodiment, the trivet frame 11 was formed in a substantially rectangular shape, and the multiple trivet claws 12 had various shapes depending on the joining position with the trivet frame 11. In contrast, in the trivet 10 of the fifth modified example, the trivet frame 11 is formed in a circular ring shape, and the multiple trivet claws 12 have the same shape, with the tips of the lower side portions 12c of the trivet claws 12 joined to the trivet frame 11. The buffer member 20 is mounted in a substantially horizontal direction from the radial outside of the trivet frame 11 to the lower part of the vertical side portion 12a of the trivet claws 12.
[0069] Thus, even in the fifth variant trivet 10, which differs from the previously described embodiments in the shape of the trivet frame 11 and the joining position between the trivet frame 11 and the trivet claws 12, it is possible to obtain the effect of preventing the trivet 10 from scratching the tabletop 2, and the effect of preventing the buffer member 20 from coming off the trivet 10 when the trivet 10 is lifted while it is fixed to the tabletop 2, in a manner basically similar to the previously described embodiments.
[0070] In the example shown in Figure 9, a recess 13 similar to that in the first embodiment is provided on the vertical side portion 12a, but a protrusion 14 similar to that in the second embodiment or a through hole 15 similar to that in the third embodiment may be provided on the vertical side portion 12a, and a corresponding buffer member 20 may be attached.
[0071] Figure 10 is a cross-sectional view showing the mounting configuration of the buffer member 20 in the trivet 10 of the sixth modified example. First, Figure 10(a) shows the state before the buffer member 20 is mounted on the trivet 10, as a cross-sectional view cut along a plane parallel to the vertical side 12a of the trivet claw 12. In the first embodiment described above, the buffer member 20 was mounted in a substantially horizontal direction relative to the lower part of the vertical side 12a of the trivet claw 12. In contrast, in the trivet 10 of the sixth modified example, the mounting direction of the buffer member 20 relative to the lower part of the vertical side 12a of the trivet claw 12 is not substantially horizontal, but is tilted downward.
[0072] Corresponding to this, the recessed portion 13 of the vertical side portion 12a is inclined downward toward the back side. Also, the protruding portion 21 of the buffer member 20 is inclined downward toward the tip. When the buffer member 20 is attached to the trivet 10, the protruding portion 21 of the buffer member 20 is pressed into the recessed portion 13 of the vertical side portion 12a obliquely downward with respect to the horizontal direction.
[0073] 10(b) shows the state in which the buffer member 20 is attached to the trivet 10. In the trivet 10 of the sixth modification, the attachment direction of the buffer member 20 to the vertical side portion 12a of the trivet claw 12 intersects with the up-down direction, which is the attachment and detachment direction of the trivet 10 to and from the tabletop 2, but is not approximately perpendicular. In particular, the angle between the direction in which the trivet 10 is lifted and removed (upward) and the attachment direction of the buffer member 20 (diagonally downward) is an obtuse angle. As a result, when an attempt is made to lift the trivet 10 upward with the abutment portion 20c of the buffer member 20 fixed to the tabletop 2, part of the upward force acting to lift the trivet 10 acts in a direction that encourages the attachment of the buffer member 20 (deepening insertion of the protrusion 21 into the recess 13), making it possible to more effectively prevent the buffer member 20 from coming off the trivet 10 than when the buffer member 20 is attached in a substantially horizontal direction.
[0074] When the buffer member 20 is fixed to the tabletop 2, if the direction in which the trivet 10 is lifted and removed and the direction in which the buffer member 20 is attached are parallel (both upward), the upward force for lifting acts directly in the direction in which the buffer member 20 is removed, and the buffer member 20 easily comes off the trivet 10. Also, if the direction in which the trivet 10 is lifted and removed and the direction in which the buffer member 20 is attached intersect and the angle between the two directions is acute, although part of the upward force for lifting acts in the direction in which the buffer member 20 is removed, the buffer member 20 is more difficult to remove from the trivet 10 than if the two directions were parallel. As the angle between the two directions increases, the force acting in the direction in which the buffer member 20 is removed decreases, and when the attachment direction of the buffer member 20 is approximately horizontal, the attachment direction is approximately perpendicular to the direction in which the trivet 10 is lifted and removed, so the upward force for lifting does not act in the direction in which the buffer member 20 is removed. Furthermore, when the angle between the direction in which the trivet 10 is lifted and removed and the direction in which the buffer member 20 is attached is obtuse, part of the upward force used to lift it acts in a direction that encourages the attachment of the buffer member 20, making it possible to prevent the buffer member 20 from coming off the trivet 10.
[0075] The above describes various embodiments and modifications of the trivet 10, but the present invention is not limited to the above embodiments and modifications, and can be implemented in various forms within the scope of its gist. [Explanation of symbols]
