  The present invention relates to a stainless steel pan cover fitted with a glass window for use in a cooking pan. Generally, a cooking pan cover is made of a single piece made of light metal

  such as aluminum and aluminum alloy In order to observe-

  ver the state of the food during cooking, for example as shown in Figure 5, a glass window of

  large diameter 101 can be made in the center of the cover

  stove key 100 made of light metal.

  To make such a glass window 101 as shown in FIG. 5, firstly, a large diameter hole 103 is made in the main body 102 of the pan lid as shown in FIG. 6 (A),

  and the inner edge of the large diameter hole 103 is re-

  folded inward as indicated by the arrow X and a

  tubular rim 104 extending downwards is produced.

  Then, as shown in Figure 6 (B), the upper part of the rim 104 is folded outward in the radial direction of the large diameter hole 103 thus forming a step portion 105 Then, as shown in Figure 6 ( C), a reinforced glass 106 is adjusted in the rung portion 105 from below, and the lower edge of the rim 104 is crimped inwards in the radial direction of the large diameter hole 103 as indicated by the arrow Z,

thus fixing the reinforced glass 106.

  Recently, however, given that consumers

  mateurs tend to prefer expensive products, usten-

  stainless steel kitchen siles have been more re-

  and, as a result, there is a growing demand for a stainless steel stove cover fitted with a

glass window.

  However, when a stainless steel stove cover-

  dable is made according to the process of Figure 6, a dif-

  f icultation of realization appears during the step of forming the rim 104 in (C), and the lower edge of the rim 104 is broken during crimping Consequently, the shape

  as shown in Figure 5 cannot be done

  seated using stainless steel, and a stainless steel stove cover fitted with a glass window does not

cannot be manufactured.

  Consequently, the main object of the present invention is

  cipal to solve the aforementioned problems Other objects and effects of the invention will be better understood and appreciated from

  the detailed description which follows.

  the outside in the radial direction of the large diameter hole

  meter, integral with the lower side of its edge

  inside, a stainless steel ring, the edge of which

  is fixed thanks to this holding part is pre-

  seen separately, and this ring has a cylindrical lens adjustment portion extending downward from the outer edge and an inner rim extending inward

  radially from the bottom edge of the fitting part

  glass, and the reinforced glass is fixed between the part

  and the internal rim.

  Another embodiment of the invention relates to a stainless steel stove cover equipped with a glass window, comprising a main stainless steel body having a large diameter hole in its center, and a reinforced glass to be adjusted. in the large diameter hole, in which the main body has a

  holding part whose cross-sectional surface is an opening

  TI-shaped outward in the radial direction of the

  large diameter hole, integral with the underside

  laughing at its inner edge, a first stainless steel ring, the lower edge of which is fixed by means of this holding part, is provided separately, the first ring having a hinge part whose cross-sectional surface is a W-shaped opening inward in the radial direction of the large diameter hole, integral with the lower side of its outer edge, a second ring of stainless steel, the outer edge of which is fixed thanks to this articulation part is provided separately, the second ring has body therewith a cylindrical adjustment portion of the lens extending downwardly from its inner edge, and an inner rim extending inwardly radially from the lower edge of the adjustment portion of the lens, and the reinforced glass is fixed

  between the holding part and the inner rim.

  Thus, according to the invention, since the

  inner rim of the ring keeps the glass reinforced

  jointed with the main body holding part, the inner rim will not be hardened or broken during the process of fitting the reinforced glass Therefore,

  thanks to the invention, it is possible to manufacture a cover

  stove key with a window having a fitted glass in the main body in stainless steel, and the product suitable for the recent high-end trend can be

mass produced.

  According to the invention, moreover, since the stainless steel ring is either the first, or the second ring having the inner edge fixed by the holding part.

  are provided only separately, the manufacturing process

  tion is not complicated, and inexpensive and

rigid can be realized.

  The invention is explained below with reference

to the accompanying drawings.

  then its lower side, and is held between the in-

  lower part of the holding part 15 and the upper side of the inner rim 18 The reference numeral 21 designates an adjustment hole perforated in the middle of the reinforced glass 20.

  The manufacturing process of the first embodiment

  The invention is explained with reference to Fig.

gure 2.

  As shown in Figure 2 (A), a large diameter hole 11 is made in the main body 10,

  and its edge part is curved towards the lower side com-

  me indicated by the arrow X Then, as shown in Figure 2 (B), the lower edge of the inner edge curved to the lower side during step (A) is curved

  outward in the radial direction of the large diameter hole

  meter 11 as indicated by the arrow Y, and it is crimped together with the inner edge of the ring 16 distinct from the main body 10 As a result, the TT-shaped holding part in section is formed, and simultaneously

  the ring 16 is fixed by the holding part 15.

  Then, as shown in Figure 2 (C), the wired glass is adjusted to the glass adjusting portion 17 of the ring 16 from the bottom side, and the proximity of the outer circumference of the upper surface of the glass comes in abutment against the lower surface of the holding part 15 In this state, the lower edge of

  the glass adjustment part 17 is crimped inwardly

  laughing in the radial direction of the large diameter hole 11 as indicated by the arrow Z and the outer edge of the glass 20 is fixed As a result, the inner rim 18 is

  formed, and the outer circumference of the glass 20 is main-

  held between the lower side of the holding part 15 and the upper side of the rim 18, so as to be fixed securely. The surface of the main body 10 is treated by

  grinding or the like as required (e.g.

  emery). In the second embodiment shown in Figure 3, the holding portion 15 fixes the inner edge of the first ring 30 made of stainless steel.

  outer edge of the first ring 30, a part of articulation

  T-shaped sectional linkage 31 is formed so as to be bent downwards and open on the side of the large diameter hole 11, and by this articulation part 31, the outer edge of the second steel ring 32 is fixed

  stainless The second ring 32 has a cylindrical part

  glass adjustment plate 17 extending downward from its inner edge, and an inner rim 18 extending

  down in the radial direction from the bottom edge

  of the glass adjustment part 17, all in one piece, and the reinforced glass 20 is fixed between the inner rim 18

and the holding part 15.

  The manufacturing process of the second embodiment

  Readout is explained below with reference to Figure 4.

  As shown in Figure 4 (A), the holding portion 15 is formed on the main body 10, and the inner edge of the ring 30 is crimped At this stage, the ring 30 has a cylindrical rim 30a towards the low

  on the outer edge, and a radial interval L1 is metered

  swam between the end face of the holding part 15

  and the inner circumference of the cylindrical rim 30 a.

  As shown in Figure 4 (B), therefore

  quent, the ring 32 is arranged on the lower side of the

  main body 10, and the second ring 32 is adjusted by-

  then the lower side opposite the interval Ll as indicated by the arrow A In the glass adjustment part 17 of the second ring 32, the reinforced glass 20 is first of all adjusted, and the lower surface of its edge ex- is supported by the upper surface of the rim

interior 18.

  Finally, as shown in Figure 4 (C), the cylindrical rim of the ring 30 is crimped inward

  in the radial direction as indicated by the arrow Z In re-

  As a result, the ring 30 constitutes the first ring, and simul-

  temporarily supports the outer edge of the second ring 30 thanks to the articulation part 31 formed on its edge

  Consequently, the first ring 30 is supported

  fully supported by the main body 10 by the holding part 15, and the first and second rings 30, 32

  are hinged in block to support the reinforced glass 20.

  Using this structure, when fixing

  wired glass 20, it is not necessary to crimp the

  holding tie 15 and the inner rim 18 directly using a press, and as a result the assembly operation can be carried out without creating a significant impact on the

glass 20.

  Some of the embodiments of the invention

  are described in detail here, but these are not limited to

  tifs and can be modified or changed without departing from the scope and spirit of the invention In addition although reference has been made to a pan, the invention may be applied

  to other utensils such as pots and the like.
