Description

The present invention relates to a top ring that is used in a roaster that heats foodstuffs using a heating section provided in an opening formed on a tabletop such as a table or a countertop, and that detachably covers the peripheral edge of the opening formed on the tabletop.

Patent Document 1 discloses a smokeless roaster that cooks grilled meat or the like on a table or the like. A smokeless roaster consists of a heating section that uses gas combustion equipment, charcoal, etc. in a circular opening formed on a table or other surface, a cooking means placed above the heating section on which a grill is placed, and a tabletop. The tabletop includes a circular mounting ring provided at the periphery of the opening of the tabletop, and a circular top ring placed on the mounting ring to cover the periphery of the opening of the tabletop. In this smokeless roaster, food such as meat is placed on a grill and cooked by a heating section.

JP2014-059142A

The smokeless roaster of Patent Document 1 has a circular grill grill installed inside a circular opening, but as shown in Fig. 1, a so-called square roaster has a rectangular grill or plate installed inside a rectangular opening. Type smokeless roasters are also commonly used in restaurants such as yakiniku restaurants. A square smokeless roaster has a rectangular grill or plate installed in a rectangular opening, and a square top ring is removably attached to the periphery of the rectangular opening. The conventional rectangular top ring shown in FIG. 9 includes a rectangular cylinder part that is rectangular in plan view and covers the lower side of the opening, and extends outward from the upper end of the rectangular cylinder part to cover the outer peripheral edge of the opening. and a flange portion that comes into contact with the upper surface of the flange.

When meat and other foods are cooked in a smokeless roaster, the top ring gets contaminated with oil and other dirt that is scattered when the meat and other foods are cooked, so it is necessary to remove the top ring and clean it regularly. . When removing the top ring from the opening on each table in the store and taking it to the washing area in the kitchen, it is possible to transport it efficiently by stacking the rectangular top rings one above the other in multiple tiers. When multiple rectangular top rings are stacked so that their longitudinal directions are vertical and parallel, the rectangular cylinder part of the upper top ring fits into the rectangular cylinder part of the lower top ring at an angle, and the multiple rectangular top rings It was difficult to stack them so that their longitudinal directions were parallel. Also, if multiple square top rings are stacked alternately so that their longitudinal directions are perpendicular to each other, the square cylinder part of the upper top ring will not fit into the square cylinder part of the lower top ring at an angle. , since the upper top ring is not locked to the lower top ring, the upper top ring easily slips on the top surface of the lower top ring and falls, making it difficult to carry many top rings at once. It was becoming difficult. An object of the present invention is to stack top rings vertically in multiple stages to make them easier to carry.

In order to solve the above-mentioned problems, the present invention is a top ring that is used in a roaster that heats ingredients using a heating section provided in an opening formed on a tabletop, and that removably covers the periphery of the opening. A plurality of side walls covering the sides of the lower side, a rectangular cylinder part having a plurality of corners formed between these plurality of side walls, and an outer peripheral edge of the opening extending outward from the upper end of the rectangular cylinder part. The rectangular cylindrical part has a pair of downward extending parts at the bottom of a pair of opposing side walls that extend below the lower ends of the other side walls, and the downward extending part Each of the pair of side walls including the downwardly extending portion is sloped linearly toward the inside of the rectangular cylinder portion as it goes downward, thereby reducing the length between the outer sides of the pair of downwardly extending portions . The present invention provides a top ring characterized in that the length is shorter than the length between the inner sides of the upper parts of a pair of side walls.

In the top ring configured as described above, the rectangular cylindrical portion has a pair of downwardly extending portions extending downwardly from the lower ends of the other sidewalls at the lower portions of the pair of side walls that face each other, and Each of the pair of side walls including the downwardly extending portion is sloped linearly toward the inside of the rectangular cylinder portion as it goes downward, so that the length between the outside of the pair of downwardly extending portions is equal to the length between the pair of sidewalls . The length is shorter than the length between the top and inside of the side walls. When the top rings are stacked one above the other so that the direction in which the pair of side walls are lined up is the same, the length between the outer sides of the pair of downwardly extending parts of the upper top ring is the length between the pair of lower top rings. Since the length is shorter than the length between the upper inner sides of the side walls of the upper top ring, the pair of downwardly extending portions of the upper top ring are inserted into the upper part between the pair of side walls of the lower top ring. In this state, the pair of downwardly extending portions of the upper top ring are restricted from moving in the direction in which the pair of side walls are lined up between the upper portions of the pair of side walls of the lower top ring. In the direction in which the pair of side walls are lined up, it becomes difficult to slip off the lower top ring, making it easier to carry by stacking the top ring vertically in multiple tiers. It can eliminate the need for a large storage space. In addition, the top rings are stacked one on top of the other so that the pair of side walls are lined up in the same direction, and the downwardly extending portions of the pair of upper top rings are fitted into the upper part between the pair of side walls of the lower top ring. When the upper top ring is inserted, the lower end of the side wall other than the pair of side walls of the upper top ring comes into contact with the side wall or flange part of the lower top ring other than the pair of side walls, so that the pair of upper top ring The downwardly extending portion of the top ring does not fit tightly into the upper portions of the pair of side walls of the lower top ring, and the upper top ring does not become difficult to remove from the lower top ring. Furthermore, since each of the pair of side walls having a downwardly extending portion at the bottom is inclined linearly toward the inside of the rectangular cylinder portion as it goes downwards, including the downwardly extending portion, processing of the top ring is troublesome. Not only is it less likely that dirt will be applied, but since no stepped portion is formed on the side wall having the downwardly extending portion, it is possible to prevent dirt from remaining on the pair of side walls.

In the top ring configured as described above, a recessed portion recessed inward in the width direction is formed at both widthwise ends of the downwardly extending portion, and the recessed portion is formed in the side wall adjacent to both sides of the sidewall having the downwardly extending portion. It is preferable that the thickness of each of the side walls is larger than that of each of the adjacent side walls and smaller than twice the thickness of each of the adjacent side walls. When the top rings are stacked one above the other so that the pair of side walls facing each other are in the same direction, the thickness of the recess is larger than the thickness of each of the side walls adjacent to both sides of the side wall having the downwardly extending portion, so that the upper top ring The downwardly extending portion of the recessed portion allows the downwardly extending portion to be inserted into the inner side of the side wall adjacent to the pair of side walls. Furthermore, since the recessed portion is smaller than twice the thickness of each side wall adjacent to both sides of the side wall having the downwardly extending portion, the gap formed between the recessed portion of the downwardly extending portion and the adjacent sidewalls is Even if the upper top ring becomes smaller than the thickness of the side walls and shifts in the width direction of the pair of side walls, the upper top ring will not move more than the length of the thickness of the side wall adjacent to the pair of side walls. The side wall adjacent to the pair of side walls securely abuts the side wall or flange portion of the lower top ring adjacent to the pair of side walls, and the upper top ring is displaced in the width direction of the pair of side walls. This will prevent it from tilting inside the top ring and fitting into it.

EMBODIMENT OF THE INVENTION Below, an embodiment of the top ring of the present invention when used in a smokeless roaster will be described with reference to the drawings. As shown in FIG. 1, the top ring 10 of the present invention heats the food on the upper side of the plate B using a heating section using a gas heater, charcoal, etc. in an opening A formed on a table top such as a table or counter table. It is a top ring that is rectangular in plan view and has four (plural) corners that removably covers the periphery of the opening A. The top ring 10 of the present invention is made by stacking a plurality of top rings vertically in multiple stages to make it easier to carry.

As shown in FIG. 2, the top ring 10 includes a rectangular cylinder part 20 having four (plural) side walls 21 to 24 that are substantially rectangular in plan view and covering the lower side of the opening A; The flange portion 30 extends outward from the upper end of the portion 20 and comes into contact with the upper surface of the outer peripheral edge of the opening portion A. The rectangular cylinder part 20 has four side walls 21 to 24 and four corners formed between these four side walls 21 to 24, and has a substantially rectangular cylinder shape in plan view. The flange portion 30 has a frame shape that is approximately rectangular in plan view and extends outward from the upper edge of the square tube portion 20 that is approximately rectangular in plan view.

As shown in FIGS. 1 and 2, the rectangular cylindrical portion 20 has side walls 21 and 22 on the short side with the shorter width and side walls 23 and 24 on the longer side with the longer width. We are prepared. Four through holes 21a (the through holes in the side wall 22 are not shown) are formed in the upper part of the side walls 21 and 22 on the short sides, and these through holes 21a allow the heat of the heating section to flow through the flange. It is formed in order to suppress the transmission to the portion 30. Further, a plurality of intake holes 23a (the intake holes of the side wall 24 are omitted from the drawing) are formed at the upper part of the side walls 23 and 24 on the long sides, and these intake holes 23a are used to absorb smoke generated on the upper side of the plate B. This is for sending out the gas to the exhaust duct provided in the opening A.

As shown in FIGS. 2 and 3, the rectangular cylindrical portion 20 has a pair of downward extensions extending below the lower ends of the other side walls 23 and 24 at the lower portions of the pair of side walls 21 and 22 on the shorter sides facing each other. It is provided with exit parts 21b and 22b. While the side walls 23 and 24 extend in the vertical direction, the pair of side walls 21 and 22, including the downwardly extending portions 21b and 22b, are linearly inclined toward the inside of the rectangular cylinder portion 20 as they move downward. There is. In this embodiment, as shown at θ in FIG. 3, the side walls 21 and 22 are inclined 1° inward from the vertical direction, thereby inclining 89° inward from the horizontal direction. Since the pair of side walls 21 and 22 having the pair of downwardly extending portions 21b and 22b at the bottom thereof are inclined inwardly, the length w1 between the outer sides of the pair of downwardly extending portions 21b and 22b is It is shorter than the length w2 between the upper inner sides of the pair of side walls 21 and 22 having the downwardly extending portions 21b and 22b.

As shown in FIG. 2, recesses 21c and 22c recessed inward in the width direction are formed at both widthwise ends of the downwardly extending portions 21b and 22b. As shown in FIG. 4, the recess 21c is recessed inward in the width direction to be slightly larger than the thickness of each of the side walls 23 and 24 adjacent to the side wall 21. As shown in FIG. By making the length d of the recess 21c in the width direction larger than the thickness t of each of the side walls 23 and 24 adjacent to the side wall 21, the top ring 10 can be arranged so that the pair of side walls 21 and 22 facing each other are in the same direction. When stacked vertically, the downwardly extending portion 21b can be inserted (fitted) between the side walls 23 and 24.

Further, the recessed portion 21c is smaller than twice the thickness of each of the side walls 23 and 24 adjacent to the side wall 21 and is recessed inward in the width direction. By making the length d in the width direction of the recess 21c smaller than twice (t×2) the thickness t of each of the side walls 23 and 24 adjacent to the side wall 21, the pair of side walls 21 and 22 facing each other can be moved in the same direction. When the top rings 10 are stacked up and down so that Since the gap between the side walls 23 and 24 is smaller than the thickness of the side walls 23 and 24, the upper top ring 10 does not move more than the thickness t of the side walls 23 and 24, and the upper top ring 10 does not move more than the thickness t of the side walls 23 and 24. , 22 will not tilt in the width direction. Note that the recess 22c formed in the side wall 22 is the same as the recess 21c formed in the side wall 21 shown in FIG. 4, so illustration and description thereof will be omitted.

As shown in FIG. 5, when the top rings 10 are stacked up and down so that the pair of side walls 21 and 22 are lined up in the same direction (longitudinal direction is the same direction), as shown in FIG. The length w1 between the outer sides of the pair of downwardly extending parts 21b and 22b is shorter than the length w2 between the inner sides of the upper parts of the pair of side walls 21 and 22 having the pair of downwardly extending parts 21b and 22b. Therefore, as shown in FIG. 6, the pair of downwardly extending portions 21b and 22b of the upper top ring 10 are fitted between the upper portions of the pair of side walls 21 and 22 of the lower top ring 10. The pair of downward extending portions 21b, 22b of the upper top ring 10, which are inserted between the upper parts of the pair of side walls 21, 22 of the lower top ring 10, are connected to the pair of side walls 21, 22 of the lower top ring 10, Movement is restricted inside the upper part of the top ring 22, making it difficult for the upper top ring 10 to slide down in the direction in which the pair of side walls 21 and 22 are arranged.

Further, as shown in FIG. 7, the downward extending portion 21b of the lower part of the side wall 21 of the upper top ring 10 has both ends in the width direction extended in the width direction by the upper portions of the side walls 23 and 24 immediately adjacent to the side. Not only is the movement of the upper top ring 10 restricted, but also the gap g between the recess 21c and the adjacent side walls 23, 24 is smaller than the thickness t of each of the side walls 23, 24. The lower end is less likely to slip inward from the upper end of the side walls 23, 24 of the lower top ring 10 or from the flange portion 30. The same applies to the downwardly extending portion 22b of the lower portion of the side wall 22.

Furthermore, when the downwardly extending portions 21b and 22b of the upper top ring 10 are inserted between the upper parts of the pair of side walls 21 and 22 of the lower top ring 10, the pair of side walls of the upper top ring 10 Since the lower ends of other side walls 23 and 24 adjacent to 21 and 22 abut the upper ends of the side walls 23 and 24 of the lower top ring 10 or the flange portion 30, the downwardly extending portions 21b and 22b of the upper top ring 10 is not inserted to the bottom of the pair of side walls 21 and 22 of the lower top ring 10. As a result, the downwardly extending portions 21b and 22b of the upper top ring 10 are firmly fitted between the pair of side walls 21 and 22 of the lower top ring 10, and the upper top ring 10 is lowered. It does not become difficult to remove from the side top ring 10.

The top ring 10 configured as described above is used in a smokeless roaster (roaster) that heats food using a heating section provided in an opening A formed on a tabletop, and removably covers the peripheral edge of the opening A. It is something. This top ring 10 has a rectangular shape having four (plural) side walls 21 to 24 covering the lower side of the opening A and a plurality of corners formed between these four side walls 21 to 24. This is a so-called rectangular top ring that includes a cylindrical portion 20 and a flange portion 30 that extends outward from the upper end of the rectangular cylindrical portion and abuts the upper surface of the outer peripheral edge of the opening A.

In this top ring 10, the rectangular cylindrical portion 20 includes a pair of downwardly extending portions 21b, 22b extending below the lower ends of the other sidewalls 23, 24 at the lower portions of a pair of side walls 21, 22 facing each other. The length between the outer sides of the downwardly extending parts 21b and 22b is made shorter than the length between the inner sides of the upper parts of the pair of side walls 21 and 22. When the top rings 10 are stacked up and down so that the pair of side walls 21 and 22 are lined up in the same direction, the length between the outer sides of the pair of downwardly extending parts 21b and 22b of the upper top ring 10 Since w1 is shorter than the length w2 between the upper inner sides of the pair of side walls 21 and 22 of the lower top ring 10, the pair of downwardly extending portions 21b and 22b of the upper top ring 10 are The top ring 10 is fitted into the upper part between the pair of side walls 21 and 22. In this state, the pair of downwardly extending portions 21b and 22b of the upper top ring 10 move between the upper parts of the pair of side walls 21 and 22 of the lower top ring 10 in the direction in which the pair of side walls 21 and 22 are lined up. Since the upper top ring 10 is restricted from sliding off the lower top ring 10 in the direction in which the pair of side walls 21 and 22 are lined up, the top ring 10 can be stacked vertically in multiple stages and carried easily. Furthermore, since the top rings 10 can be stably stacked vertically in multiple stages, a large storage space is not required.

Furthermore, the top rings 10 are stacked vertically so that the pair of side walls 21 and 22 are lined up in the same direction, and the pair of downwardly extending portions 21b and 22b of the upper top ring 10 are connected to the lower top ring 10. When inserted into the upper part between the pair of side walls 21, 22, the lower ends of the other side walls 23, 24 other than the pair of side walls 21, 22 of the upper top ring 10 are the pair of side walls of the top ring 10 on the lower side. By abutting against the side walls 23, 24 other than 21, 22 or the flange portion 30, the pair of downwardly extending portions 21b, 22b of the upper top ring 10 connects to the pair of side walls 21, 22 of the lower top ring 10. The upper top ring 10 does not become difficult to remove from the lower top ring 10.

In this top ring 10, recesses 21c and 22c recessed inward in the width direction are formed at both widthwise ends of the downwardly extending portions 21b and 22b, and the recesses 21c and 22c have downwardly extending portions 21b and 22b. It is formed to be larger than the thickness t of each of the side walls 23 and 24 adjacent to both sides of the side walls 21 and 22, and smaller than twice the thickness t of each of the adjacent side walls 23 and 24. When the top rings 10 are stacked up and down so that the pair of side walls 21, 22 facing each other are in the same direction, the recesses 21c, 22c are adjacent to both sides of the side walls 21, 22 having the downwardly extending portions 21b, 22b. Since the thickness is larger than the thickness t of each of the side walls 23 and 24, the downwardly extending portions 21b and 22b of the upper top ring 10 can be inserted into the inner side of the side walls 23 and 24 adjacent to the pair of side walls 21 and 22 through the recesses 21c and 22c. It becomes a state. Further, since the recesses 21c and 22c are smaller than twice (2×t) the thickness t of each of the side walls 23 and 24 adjacent to both sides of the side walls 21 and 22 having the downwardly extending portions 21b and 22b, the downwardly extending portions 21c and 22c The gap g formed between adjacent side walls 23 and 24 by the recesses 21 c and 22 c of 21 b and 22 b is smaller than the thickness t of the adjacent side walls 23 and 24 , so that the upper top ring 10 is connected to the pair of side walls 21 and 22 . Even if the upper top ring 10 shifts in the width direction, the upper top ring 10 does not move more than the length of the thickness t of the side walls 23, 24 adjacent to the pair of side walls 21, 22. The side walls 23, 24 adjacent to the pair of side walls 21, 22 of the lower top ring 10 reliably abut the side walls 23, 24 adjacent to the pair of side walls 21, 22 or the flange portion 30, and the upper top ring 10 contacts the pair of side walls 21, 22. Due to this shift in the width direction, the top ring 10 tilts inside the lower top ring 10 and does not fit into it.

In this top ring 10, each of the pair of side walls 21, 22 having the downwardly extending portions 21b, 22b at the bottom thereof extends toward the inner side of the rectangular cylinder portion 20 as it goes downward including the downwardly extending portions 21b, 22b. By inclining linearly, the length between the outer sides of the pair of downwardly extending portions 21b and 22b is made shorter than the length between the inner sides of the upper portions of the pair of side walls 21 and 22. By doing this, not only does it take less time and effort to process the top ring 10, but also because no stepped portion is formed on the side walls 21 and 22 having the downwardly extending portions 21b and 22b. It can prevent dirt from remaining. In this embodiment, the pair of side walls 21 and 22 including the downwardly extending portions 21b and 22b are linearly inclined inward as they proceed downward, so that the pair of downwardly extending portions 21b , 22b is made shorter than the length between the upper inner sides of the pair of side walls 21 and 22, but the invention is not limited to this. 21 and 22 are made to extend vertically without being inclined, and a stepped portion extending horizontally (or diagonally downward) inward is formed at the lower end of the side walls 21 and 22, and from the tip of the stepped portion It is also possible to form downwardly extending portions 21b and 22b that extend downwardly. Even in this case, the upper top ring 10 can be prevented from slipping off in the direction in which the pair of side walls 21 and 22 are lined up.

The rectangular cylinder part 20 of the top ring 10 of the above embodiment is approximately rectangular in plan view as a rectangular cylinder part having a plurality of side walls and a plurality of corners formed between the plurality of side walls. , but is not limited to this, and may be a square in plan view, or any polygon that is larger than a quadrilateral in plan view, and is preferably an even-numbered polygon, particularly an even-numbered regular polygon. . Further, each corner of the rectangular cylinder portion may be rounded to have a curved surface shape.
