Description

  The present invention relates to a stove packing, and more particularly to a stove packing used for closing a corner portion formed between a top plate of a counter into which a drop-in stove is fitted and a top plate of the stove.

  FIG. 11 is a perspective view showing a state where the stove is fitted in the counter, and FIG. 12 is an enlarged schematic end view of the XII-XII line shown in FIG.

  Referring to these drawings, the stove (IH cooking heater) 31 is fitted into the counter 35 by the frame 33 provided on the outer periphery of the top plate 32 being hooked on the top surface of the top plate 36 of the counter 35. Fixed in state. At this time, a rubber packing 38 or the like is disposed between the frame 33 and the top surface of the top plate 36 in order to prevent the frame 33 and the top surface of the top plate 36 from being in direct contact with each other. . As a result, the frame 33 and the top surface of the top plate 36 are not in direct contact with each other, but a gap 40 is generated at a corner portion between the frame 33 and the top surface of the top plate 36. When dirt or the like enters the gap 40, there is a problem that the dirt or the like is difficult to remove and becomes unsanitary.

  Then, the gap tape for kitchens as shown in patent documents 1 is proposed.

  FIG. 13 is an enlarged end schematic view showing the use state of the kitchen gap tape shown in Patent Document 1, and corresponds to FIG.

  Referring to the drawing, kitchen gap tape 61 is formed in a long band shape by applying an adhesive on one side. In use, a crease extending in the longitudinal direction is formed in the kitchen gap tape 61, and the second adhesive part 64, which is the lower part of the fold, is provided so that the first adhesive part 63, which is the upper part of the crease, is along the outer surface of the frame 33. Affixed to the upper surface of the top plate 36. Then, the entrance of the gap 40 is blocked, and dirt or the like does not enter the gap 40.

  However, although the kitchen gap tape 61 as described above prevents entry of dirt into the interior, dirt accumulates in the corner portion 66 formed by the first adhesive portion 63 and the second adhesive portion 64. In addition, it is difficult to continuously stick to the corner of the frame 33 in plan view. Furthermore, once peeled off, the adhesive is peeled off and the adhesive strength is lowered, so it is necessary to replace it with a new one. Furthermore, the adhesive of the kitchen gap tape 61 remains on the portion of the frame 33 and the top plate 36 where the kitchen gap tape 61 has been attached, which is likely to cause new dirt.

  Thus, a stove packing as shown in Patent Document 2 has been proposed.

  FIG. 14 is a perspective view of the stove packing shown in Patent Document 2, FIG. 15 is a perspective view showing a use state of the stove packing shown in FIG. 14, and FIG. It is an enlarged end surface schematic diagram of the XVI-XVI line shown in Drawing 10, and is a figure corresponding to Drawing 13 of the conventional gap tape for kitchens.

  Referring to these drawings, the stove packing 71 is made of an elastic body formed into a deformable rod shape having a constant cross-sectional shape by extruding a molten material made of styrene resin, and the whole is constant. Adhesive. The cross-sectional shape includes a first protrusion 73, a second protrusion 74 connected to the top of the first protrusion 73, a placement part 75 connected to the side of the first protrusion 73, and a second And an inclined portion 76 that gently inclines from the upper end portion of the projecting portion 74 toward the side end portion of the mounting portion 75. The length of the stove packing 71 is longer than the total length of the outer periphery of the stove 31 so that the entire outer periphery of the stove (IH cooking heater) 31 is continuously surrounded by one stove packing 71. Yes.

  In use, referring to FIG. 15 and FIG. 16, the first protrusion 73 is formed in the gap 40 between the frame 33 provided on the outer periphery of the top plate 32 of the stove 31 and the top surface of the top plate 36 of the counter 35. Insert and install the stove packing 71.

  In installing the stove packing 71, the first protrusion 73 is pushed into the gap 40 using the elastic deformation of the stove packing 71, the mounting portion 75 is placed on the top plate 36, and the second protrusion 74 is further moved. A stove packing 71 is pressed along the outer surface of the frame 33 toward the frame 33 and the top plate 36 from the inclined portion 76 side. Then, the second protrusion 74 is in close contact with the frame 33 and the mounting portion 75 is in close contact with the top plate 36. Further, a gentle inclination is formed by the inclined portion 76 from the frame 33 toward the top plate 36.

  When the stove packing 71 is installed on the entire outer periphery of the stove 31, the stove packing 71 is installed along the frame 33 from one place on the side surface of the frame 33. In the corner portion of the frame 33, when the stove packing 71 is installed while being pulled lightly, the stove packing 71 is neatly installed along the shape of the corner portion of the frame 33.

  As described above, since the stove packing 71 is formed longer than the total length of the outer periphery of the stove 31, the stove packing that remains after the stove packing 71 has been installed on almost the entire outer periphery of the stove 31. The length of the packing 71 is longer than the length of the portion of the stove 31 where the stove packing 71 is not yet installed. Therefore, a part of the remaining part of the stove packing 71 is cut off so that the end face of the remaining part of the stove packing 71 is connected to the first end face when the stove packing 71 is installed. Adjust the length. Then, the remaining portion of the stove packing 71 is installed, the first end surface of the stove packing 71 and the end surface of the remaining portion are abutted, and the installation of the stove packing 71 is completed.

  If comprised in this way, the adhesiveness of the stove packing 71 and the flame | frame 33 grade | etc., Will increase with the adhesive force of the stove packing 71. Further, since the frictional force between the mounting portion 75 and the top plate 36 is also increased by the adhesive force, the stove packing 71 is not easily displaced from the gap 40. Therefore, the state is maintained also in the corner portion of the frame 33.

  Further, in the stove packing 71, a gentle inclination is formed by the inclined portion 76 instead of the corner portion 66 formed in the conventional kitchen gap tape 61 shown in FIG. Dirt is less likely to accumulate in the stove packing 71 itself.

Furthermore, since the material for the stove packing 71 has adhesiveness, the adhesive strength does not decrease by removing or washing, and the stove packing 71 can be used repeatedly.
Furthermore, since no adhesive is used, it does not cause new dirt caused by the adhesive remaining.

  FIG. 1 is a plan view showing a schematic shape of a stove packing according to the first embodiment of the present invention, FIG. 2 is an enlarged end view taken along line II-II shown in FIG. 1, and FIG. FIG. 4 is a plan view showing a schematic shape of a stove packing in a state in which the connector shown in FIG. 1 is separated, and FIG. 4 is an enlarged schematic view of an “X” portion shown in FIG.

  First, referring to FIG. 1 and FIG. 2, the stove packing 1 includes a deformable rod-shaped elastic member 10 having a constant cross-sectional shape and stretchability in the axial direction, and a connector 20. It consists of a configured ring-shaped elastic body. The length of the elastic body is set to be shorter than the total length (about 220 mm) of the corner portion 37 corresponding to the entire circumference of the frame 33 of the stove 31 described later. The effect by having comprised in this way is mentioned later.

  The elastic member 10 is connected to the first protrusion 11 along the outer surface of the frame, which will be described later, the mounting portion 13 mounted on the top plate, which will be described later, and the lower portion of the first protrusion 11. A slanted portion 14 that gently slopes toward the side end of the slanted portion, a bendable bendable portion 15 connected to the inward side of the slanted portion 14, and a second protrusion connected to the inward side of the bendable portion 15. Part 12. The lower surface of the mounting portion 13 and the lower surface of the second projecting portion 12 are adjacent to each other via a recess 16 formed in the lower portion of the bent portion 15. The effect by having comprised in this way is mentioned later. The thickness H of the second protrusion 12 is set to 0.85 mm and the width L is set to 1.19 mm.

  The elastic member 10 is an acrylic elastomer in which the inner side of the first projecting portion 11, the inner side and the lower surface side of the second projecting portion 12, and the lower surface side of the mounting portion 13 are adhesive. The other parts other than are made of an acrylic elastomer having non-tackiness, and are formed by two-color extrusion molding.

  If comprised in this way, since the part which contact | connects the flame | frame and top plate mentioned later has adhesiveness, the shift | offset | difference at the time of attachment reduces, Therefore The attachment state of the stove packing 1 is stabilized. In addition, since it is possible to impart adhesiveness to a desired portion at a portion in contact with another portion, the adhesive performance is stabilized and the adhesion of dirt to the other portion is reduced. Furthermore, since the length of the elastic member 10 becomes flexible, it is advantageous in terms of cost.

  Next, referring to FIG. 3 and FIG. 4, the connector 20 includes a male part 21 and a female part 26 that are paired with each other, and the end part 18 a of the elastic member 10 is elastic to the male part 21.

  Next, referring to (2) of FIG. 5, the elastic member 10 is pulled forward from the state of (1) of FIG. 5 (downward in the drawing). Then, as described above, since the elastic member 10 has elasticity in the axial direction, the elastic member 10 extends. Therefore, the elastic member 10 is stretched, and the shape of the stove packing 1 is changed so that the length of the stove packing 1 is equal to or greater than the total length of the corner portions 37.

  Finally, referring to (3) of FIG. 5, the pulling force on the elastic member 10 is released with the position of the elastic member 10 aligned with the corner portion 37. Then, as described above, since the stove packing 1 has a ring shape, all of the corner portions 37 are integrally closed, so that the mounting state is stabilized. Further, since the elastic member 10 has a stretchability in the axial direction and the length of the stove packing 1 is set shorter than the total length of the corner portion 37, the stove packing 1 is attached in a tensioned state. It is done. Therefore, the close contact state with the corner portion 37 is improved.

  6 is a schematic diagram showing an enlarged end surface of the VI-VI line shown in FIG. 5 and a state in which the stove packing shown in FIG. 1 is attached to the corner of the frame.

  First, referring to (1) of FIG. 6, the mounting portion in a state in which the second protrusion 12 of the stove packing 1 is inserted into the gap 40 of the corner portion 37 generated between the frame 33 and the top plate 36. 13 is placed on the top plate 36, and the stove packing 1 is pressed toward the frame 33 and the top plate 36 from the inclined portion 14 side. Then, the lower surface of the mounting portion 13 is pushed into the frame 33 side, and the stove packing 1 changes from the shape indicated by the two-dot chain line in the figure to the shape indicated by the solid line in the figure, and the first protrusion 11 is The placing portion 13 is in close contact with the frame 33 and the top plate 36. Further, a gentle inclination is formed by the inclined portion 14 from the frame 33 toward the top plate 36.

  FIG. 7 is a schematic view showing a process of correcting the mounting state of the stove packing shown in FIG.

  First, with reference to (1) of FIG. 7, a part of the elastic member 10 of the stove packing 1 is twisted. In this state, the corner portion 37 is not closed. Moreover, in this state, since the stove packing 1 is ring-shaped, twist cannot be eliminated.

  Therefore, referring to (2) of FIG. 7, the connector 20 of the stove packing 1 is separated into a male part 21 and a female part 26. Then, the stove packing 1 has a single bar shape as a whole, and the elastic member 10 can be freely twisted in the axial direction, so that the twist can be eliminated.

  Finally, referring to (3) of FIG. 7, the male portion 21 and the female portion 26 are connected again in a state where the twist is eliminated, and the stove packing 1 is attached to the frame 33. If it does in this way, all the corner parts 37 will be obstruct | occluded integrally and the attachment state of the stove packing 1 will be corrected.

  By the way, in the mounting method of the elastic member 10 described above, when there is no gap 40 in the corner portion 37 formed between the frame 33 and the top plate 36, and when the gap 40 is small enough to prevent the second protrusion 12 from being inserted sufficiently. Can not attach the stove packing 1.

  Therefore, the shape of the stove packing 1 is deformed as follows, and the stove packing 1 is attached to the one having no gap 40 generated between the frame 33 and the top plate 36.

  8 is a plan view showing a schematic shape in a state where the elastic member of the stove packing shown in FIG. 1 is strongly pulled, and FIG. 9 is an enlarged end view of the IX-IX line shown in FIG. 10 is an enlarged end schematic view showing the mounting state of the stove packing shown in FIG. 8 and a schematic view showing the mounting state to the corner portion of the frame in the portion corresponding to the VI-VI line shown in FIG. It is.

  First, referring to FIGS. 8 and 9, the elastic members 10 of the stove packing 1 are strongly pulled by hands 80 a and 80 b so as to slightly warp outward. Then, as described above, since the elastic member 10 has elasticity in the axial direction and the bending portion 15 is configured to be freely bent, the second protrusion 12 contacts the inner side of the first protrusion 11. Thus, the cross-sectional shape changes to the shape shown in FIG.

  While maintaining this tensioned state, the stove packing 1 is attached in the same manner as the attachment method shown in FIG. 5, and the mounting portion 13 is placed on the top plate 36 as shown in FIG. The stove packing 1 is pressed from the side of the portion 14 toward the frame 33 and the top plate 36. Then, the stove packing 1 changes from the shape shown by the two-dot chain line in the figure to the shape shown by the solid line in the figure, the second protrusion 12 and the first protrusion 11 are on the frame 33, and the mounting part 13 is They are in close contact with the top plate 36. Therefore, the rubber packing 39 is built in the frame 33, and there is no gap in the corner portion 37 formed between the frame 33 and the top plate 36, and the second protrusion 12 cannot be sufficiently inserted even if there is a gap. The stove packing 1 can be attached to a small one. That is, when the stove packing 1 is configured as described above, the position of the second protrusion 12 changes according to the gap 40, so that efficient mounting is possible.

  Further, a gentle inclination is formed by the inclined portion 14 from the frame 33 toward the top plate 36. Further, as described above, since the installation is performed while maintaining the tensioned state, even if the corner portion 34 of the frame 33 has a small diameter as shown in FIG. It becomes easy.

  In the first embodiment described above, the elastic member is formed by two-color extrusion molding, but may be formed by a different method.

  In the first embodiment described above, the portion in contact with the attachment target is composed of a different material with respect to the material of the other portion that does not have adhesiveness.
