Description

  The present invention relates to a metal foil molded body, and more particularly, to a metal foil molded body that is used by bending a part in the width direction in a direction perpendicular to the other part while partially shrinking the longitudinal direction.

  FIG. 5 is a view showing a use state of a gas range top plate cover made of a conventional metal foil molded body, and FIG. 6 is a gas range top plate cover of FIG. It is a top view of what to do.

  With reference to these drawings, the gas range 61 includes two burners 64 a and 64 b and a grill 70. In the gas range 61, a grill exhaust port 63 for discharging the heat of the grill 70 is formed behind the top plate 65.

  In the gas range 61, a top plate cover 66a for covering the periphery of the left burner 64a and a top plate cover 66b for covering the periphery of the right burner 64b are provided between the virtues 62a and 62b and the top plate 65, respectively. Installed on. These top plate covers 66a and 66b are configured to be symmetrical, and only the top plate cover 66a used for the left side portion of the gas range 61 will be described here.

  The top plate cover 66a is made of a metal foil molded body formed by press forming of aluminum foil, and covers the top plate cover portion 15a for covering almost the left half of the top plate 65 and the juice receiving portion around the burner 64a. The juice receiving tray covering portion 3a for this purpose.

  The top plate covering portion 15a has a substantially rectangular seat shape, and has a front flap 22a, a central flap 67a, a first rear flap 17a, and a second rear flap 19a at positions corresponding to the front, center, and rear of the gas range 61. Are formed respectively. A fold line 18a is formed at the boundary portion of the first rear flap 17a, and the first rear flap 17a can be bent and used so as to be raised forward. Therefore, when the top plate cover 66a is used in a gas range 61 of the type in which the grill exhaust port 63 is located at the rear portion of the top plate 65 as shown in FIG. 5, the grill exhaust port 63 is blocked. There is no.

  On the other hand, the juice tray cover portion 3a connected to the top plate cover portion 15a has a shape substantially corresponding to a juice tray (not shown), and an opening 4a for inserting the burner 64a is formed at the center thereof. Has been.

  When using the top plate cover 66a, with the virtues 62a removed, the soup pan cover portion 3a is fitted into a soup tray portion (not shown) so that the burner 64a is exposed from the opening 4a, and the top plate cover portion 15a is used for the top plate. It arrange | positions so that the substantially left half of 65 may be covered. And installation is completed by installing the virtues 62a from the top plate cover 66a. As for the right side portion of the gas range 61, it is possible to cover almost the entire surface of the top plate 65 by similarly attaching the top plate cover 66b.

  By using the pair of top plate covers 66a and 66b in this manner, it is possible to prevent dirt such as oil splashes and spills during cooking from directly attaching to the top plate 65.

  In the top plate cover as described above, a pair of left and right top plate covers may be used to cover almost the entire surface of the top plate. In this case, however, the seam portion of the left and right top plate covers is provided at the center of the gas range. Therefore, it is difficult to completely prevent dirt from adhering to the top plate. Therefore, in order to solve this problem, it is conceivable that a pair of left and right top plate covers are integrally formed so that a seam is not formed.

  However, in general, the distance between the burners in the two gas ranges (D shown in FIG. 5) differs depending on the product. In the case of top plate covers of different types shown on the left and right as shown in the conventional example, the tops on the left and right sides are used even in gas ranges having different burner distances (for example, those having a smaller burner distance D shown in FIG. Differences in the distance between the burners can be absorbed, for example, by overlapping the plate cover at the central portion. However, if the left and right top plate covers are connected together, the width of the openings for inserting the burners cannot be easily changed, and it is necessary to prepare a top plate cover for each distance between the burners. Will occur.

  Therefore, a top plate covering that integrally covers the left and right top plates and can be adjusted with respect to the distance between the burners is desired.

  FIG. 7 is a plan view of a gas range top plate cover considered from such a background.

  Referring to the drawing, a top plate cover 1 is formed by press molding of an aluminum foil, and a top plate cover 15 for covering the top plate of a two-mouth gas range and each of a juice tray of the gas range are provided. It consists of the juice pan cover parts 3a and 3b for covering.

  The soup pan covering portion 3a has a shape corresponding to the soup pan of the gas range, similar to that shown in the conventional example of FIG. 6, and an opening 4a for exposing the burner is formed in the center portion. Has been. The other juice tray cover 3b is formed in the same manner.

  The top plate covering portion 15 has a substantially rectangular sheet shape, and the size of the top plate covering portion 15 is configured to cover almost the entire surface of the top plate of the two-mouth gas range.

  In the central portion of the top plate cover 15, an elongated rectangular strip 13 having a short side as a direction connecting the openings 4 a and 4 b is formed. The top plate cover 15 includes a left opening 4 a. The first region 45 is separated from the second region 46 including the right opening 4b. Folding lines 26 and 27 that can be folded into valley folds are formed on the pair of long side portions of the belt-like portion 13. Further, between the folding lines 26 and 27, the folding lines 26 and 27 are respectively formed. Folding lines 25 that can be folded into mountain folds are formed at positions that are parallel and equally spaced.

  A fold line 18 is formed at the rear portion of the openings 4a and 4b of the top plate cover portion 15 so that the rear portion of the top plate cover portion 15 can be folded into a valley fold on a straight line orthogonal to the long side of the belt-shaped portion 13. Has been. A rear portion of the top plate cover 15 is defined by a rear flap 21 defined by a fold line 18. The rear flap 21 is provided so as not to block the grill exhaust port disposed on the rear side of the top plate, as in the conventional example shown in FIG.

  On the front side from the openings 4 a and 4 b of the top plate cover 15, a fold line 23 that allows the front end of the top plate cover 15 to be folded into a valley fold on a straight line orthogonal to the long side of the strip 13. A substantially rectangular front flap 22 is defined by the fold line 23 formed. This front flap 22 is used for the purpose of adjusting the dimension of the top plate cover 1 in the same direction according to the depth direction dimension of the gas range, or blocking dirt such as spillage on the top plate cover 15. Is something that can be done.

  FIG. 8 is an enlarged perspective view showing a process of bending the top plate cover shown in FIG.

  First, referring to (1) of FIG. 8, the intersection point of the fold line 18 and the fold line 25 is a point P, the point behind the fold line 18 on the fold line 25 is a point Q, the fold line 18 and the fold line 26 are. The point of intersection with the point R, and the point of intersection of the fold line 18 and the fold line 27 is point S. The belt-like portion 13 is formed with fold lines 28a and 28b that allow the line segment QR and the line segment QS to be bent into valley folds. In addition, the folding line 25 that is already in a mountain fold state is configured such that a portion on the rear side from the point Q can be folded back into a valley fold. Further, the portion of the fold line 26 on the rear side from the point R and the portion of the fold line 27 on the rear side of the point S are already in the valley fold state, but can be folded back into a mountain fold. Has been.

  Referring to (2) of FIG. 8, first, a portion of the fold line 18 excluding the line segment PR and the line segment PS is folded into a valley fold. Then, the folding lines 28a and 28b are valley-folded, and the rear part of the folding line 25 from the point Q is folded back into a valley fold. Furthermore, when the back part from the point R in the fold line 26 and the back part from the point S in the fold line 27 are folded back in a mountain fold, the cross section of the rear part from the point Q in the strip 13 is V-shaped. Deform to become a mold.

  FIG. 1 is a schematic plan view of a gas range top plate cover made of a metal foil molded body according to the first embodiment of the present invention, and FIG. 2 is an enlarged sectional view taken along line II-II shown in FIG. 3 is an enlarged sectional view taken along line III-III shown in FIG.

  Referring to these drawings, the main structure of the gas range top plate cover shown in FIG. 1 is basically the same as that shown in FIG. 7 shown in the background art. Therefore, the differences will be mainly described here.

  The gas range top plate cover according to this embodiment is greatly different in that each fold line is formed around an isosceles triangle ABC located above the center thereof. For ease of explanation, the direction in which the burner openings 4a and 4b are aligned is defined as the longitudinal direction, and the direction perpendicular thereto is defined as the width direction. A first fold line 48, which is foldable in a valley fold, is formed from the first point A to the end in the width direction in the direction opposite to the vertex C and parallel to the width direction. A second fold line 49 that is foldable in a valley fold is formed from the second point B to the vertex C in a direction opposite to the vertex C and parallel to the width direction.

  On the other hand, a third fold line 50 that is foldable in a mountain fold is formed from the first point A to the end in the width direction in the direction opposite to the first fold line 48. Similarly, a fourth fold line 51 that is foldable in a mountain fold from the second point B in the direction opposite to the second fold line 49 is formed. A fifth fold line 52 that is parallel to each of the third fold line 50 and the fourth fold line 51 from the vertex C to the end in the width direction is foldable into a valley fold. Further, a mountain fold is applied from a specific position away from the vertex C in a direction opposite to the fifth fold line 52 to a widthwise end portion parallel to each of the first fold line 48 and the second fold line 49. A sixth fold line 53 that can be bent is formed. The sixth fold line 53 is formed at a slightly higher position than the first fold line 48 and the second fold line 49. However, the sixth fold line 53 may be formed on the same plane. good.

  A seventh fold line 54 that is foldable in a valley fold is formed from the first point A to the second point B in a direction opposite to the second point B and parallel to the longitudinal direction to the longitudinal end. . On the other hand, an eighth fold line 55 that can be folded into a valley fold is formed from the second point B to the end in the longitudinal direction in the direction opposite to the seventh fold line 54. Further, a ninth fold line 56 that can be folded into a valley fold is formed as a line segment connecting the first point A and the vertex C. Further, a tenth fold line 57 that is formed as a line segment connecting the second point B and the vertex C and can be bent into a valley fold is formed. Further, in the isosceles triangular portion surrounded by the point ABC, as shown in FIG. 2 and FIG. 3, a bulging portion 47 press-formed so as to protrude to the surface side is formed. Thereby, the rigidity with respect to the bending of the portion is enhanced.

  Next, a case will be described in which the rear flap 21 is bent with respect to the top plate cover 15 while reducing the length in the longitudinal direction of the top plate cover 1 shown in FIG.

  FIG. 4 is a perspective view showing a schematic process at the time of bending.

  With reference to (1), this state shows the state before bending. From this state, the first fold line 48, the second fold line 49, and the fifth fold line 52 are changed to the valley fold state, and the third fold line 50, the fourth fold line 51, and the sixth fold line are changed. The line 53 is bent so as to be in a mountain fold state, and the seventh fold line 54 and the eighth fold line 55 are changed to a valley fold state so that the rear flap 21 is raised with respect to the top plate cover 15.

  This state is shown by (2) in FIG. Normally, when the seventh fold line 54 and the eighth fold line 55 are changed to the valley fold state, if the isosceles triangle portion on the extension line has a conventional structure, the portion can be bent at the same time. There were many. However, in this embodiment, the isosceles triangle portion has the raised portion 47 formed by press molding, so the rigidity against bending is extremely improved. Therefore, even if the seventh fold line 54 and the eighth fold line 55 are folded in a valley fold state, the raised portion 47 is not folded, and the folding of the rear flap 21 proceeds with the posture maintained.

  Further, since the first fold line 48, the second fold line 49, the ninth fold line 56, and the tenth fold line 57 are formed continuously, the isosceles triangle portion, that is, the raised portion 47 is formed by these. It will be in the state surrounded by the fold line. Therefore, the periphery of the raised portion 47 is easily folded into a valley folded state.

  FIG. 4 (3) shows a state in which the rear flap 21 is bent from the state of (2) of FIG. 4 to a substantially right angle with respect to the top plate cover 15. Even in this state, the raised portion 47 is substantially maintained in its initial shape due to its rigidity. As a result, the rear flap 21 is accurately bent with respect to the top plate cover 15 and the length of the top plate cover 1 as a whole can be adjusted very easily. In order to further reduce the length in the longitudinal direction from this state, it is sufficient to apply a force in a direction in which the portions on both sides of the fifth fold line 52 and the portions on both sides of the sixth fold line 53 are in close contact with each other. Then, a crease line is formed in an extension line shape of the sixth fold line 53 with respect to the raised portion 47, and the bent state is stabilized.

  In addition, in said embodiment, although it applies to the gas range top plate cover which consists of aluminum foil as a metal foil molded object, it can apply to other metal foils similarly, and metal foil shaping | molding of another use The same applies to the body.

  In the above embodiment, the sixth fold line 53 has an end point that is longer than the height of the isosceles triangle from the vertex C, but the end point may be inside the isosceles triangle, or the vertex C It may overlap.

  Furthermore, in the above embodiment, the bent portion is formed with reference to an isosceles triangle, but it goes without saying that the isosceles triangle may be an equilateral triangle.

  Furthermore, in the above-described embodiment, the bent portion including the raised portion with respect to the longitudinal direction is one place, but the bent portion may be separated to have two or more places, or the bent parts may be formed in a plurality of bellows shapes. It may be formed. In this case, if a raised portion is formed in each bent portion, it can be easily bent.
