  FIG. 1 is a conceptual diagram illustrating a configuration of a sealing material 100 that is an example of the sealing material of the present embodiment. FIG. 1 shows a sealing material 100 before being installed in a housing.

  The sealing material 100 includes a first part 111a, a second part 121a, and a third part 131a. 1A shows the first part 111a, FIG. 1B shows the second part 121a, and FIG. 1C shows the third part 131a. FIG. 1D shows the first part 111a as a line 199a, 199b or 199c shown in FIG. 1A, or a line 199d shown in FIG. 1B, or FIG. It is sectional drawing at the time of assuming having cut | disconnected by the line 199e to represent.

  As shown in FIG. 1A and FIG. 1D, the first part 111a includes a rectangular parallelepiped upper portion 112a, a rectangular parallelepiped hanging portion 113aa, and a rectangular parallelepiped hanging portion 113ab.

  The hanging part 113aa and the upper part 112a are connected by a boundary surface 114a represented by a line 199f.

  The hanging part 113ab and the upper part 112a are connected by a boundary surface 114b represented by a line 199g.

  The hanging part 113aa and the upper part 112a may be integrally formed. In that case, it can be said that there is no boundary between the hanging part 113aa and the upper part 112a. However, for the convenience of the following description, the hanging part 113aa and the upper part 112a are connected by the boundary surface 114a even when they are integrally formed. Suppose you are.

  The hanging part 113ab and the upper part 112a are connected by a boundary surface 114b represented by a line 199g.

  The hanging part 113ab and the upper part 112a may be integrally formed. In that case, it can be said that there is no boundary between the hanging part 113ab and the upper part 112a. However, for the convenience of the following description, the hanging part 113ab and the upper part 112a are connected by the boundary surface 114b even when they are integrally formed. Suppose you are.

  An angle 177a formed by the upper portion 112a and the hanging portion 113aa is approximately 90 degrees.

  An angle 177b formed by the upper part 112a and the hanging part 113ab is approximately 90 degrees.

  The second part 121a has a rectangular parallelepiped shape as shown in FIGS. 1 (b) and 1 (d).

  The third part 131a has a rectangular parallelepiped shape as shown in FIGS. 1 (c) and 1 (d).

  The material of the first part 111a, the second part 121a, and the third part 131a is typically rubber or resin. However, in some cases, a metal can be used as the material of the first part 111a, the second part 121a, and the third part 131a. In that case, it is desirable to use a relatively soft metal such as copper.

  When a soft material is used as the material of the first part 111a, the second part 121a, and the third part 131a, the shapes of the first part 111a, the second part 121a, and the third part 131a can be easily deformed. The shapes of the first portion 111a, the second portion 121a, and the third portion 131a described in the present embodiment are not shapes after being deformed, but shapes that are assumed at the time of processing or shapes that are naturally extended.

  FIG. 2 is a conceptual diagram showing a sealing material 100a in which the sealing material 100 shown in FIG. An arrow 194a represents the direction of gravity. The point that the arrow 194a represents the direction in which gravity works is the same in other drawings of this embodiment. In the description of the present embodiment, the direction indicated by the arrow 194a is referred to as “down” (orientation), and the opposite direction of “down” (orientation) is referred to as “up” (orientation).

  As shown in FIG. 2, the hanging part lower end 187a is located below the second part upper end 186a. The hanging part lower end 187b is located below the third part upper end 185a. The second portion upper end 186a is located in the vicinity of the drooping portion 113aa between the drooping portion 113aa and the drooping portion 113ab. The third portion upper end 185a is located in the vicinity of the drooping portion 113ab between the drooping portion 113aa and the drooping portion 113ab.

  Each of the first part 111a, the second part 121a, and the third part 131a shown in FIGS. 1 and 2 can be created, for example, by cutting out from a plate of material. Alternatively, each of the first part 111a, the second part 121a, and the third part 131a is prepared by creating a mold in advance, pouring a material melted by heat or the like into the mold, and then solidifying it by cooling. You can also. Alternatively, each of the first part 111a, the second part 121a, and the third part 131a is made by foaming in a heated state inside the mold, filling the mold, and then solidifying by cooling. You can also Alternatively, each of the first part 111a, the second part 121a, and the third part 131a can be created by creating a plurality of parts in advance and connecting these parts.

  In this case, the sealing materials 100 and 100a are manufactured at a lower cost than manufacturing an integrated sealing material having the same size and the same size as the sealing material 100a (hereinafter referred to as “integrated sealing material”). In many cases. This is because the sealing material 100a is composed of a plurality of separated parts of the first part 111a, the second part 121a, and the third part 131a.

  For example, it is assumed that the sealing material 100 is manufactured by cutting from a single material plate whose upper surface is rectangular. In that case, a plate 98a as shown in FIG. 3 is prepared, and can be manufactured by cutting perpendicularly to the plate along the line shown in FIG. The useless parts 176a and 176b are discarded as useless parts.

  On the other hand, it is assumed that the integrated sealing material 99a shown in FIG. 4 which is an example of the integrated sealing material is cut out from a single material plate having a rectangular upper surface. In that case, the plate 98b shown in FIG. 5 can be prepared and cut perpendicularly to the plate along the line shown in FIG. The wasted portions 176c, 176d, and 176e are discarded as wasted portions.

  As apparent from a comparison between FIG. 3 and FIG. 5, first, the plate 98b shown in FIG. 5 is larger than the plate 98a shown in FIG. Larger plates are more expensive when the materials are the same. Further, the waste portions 176c, 176d, and 176e shown in FIG. 5 are larger in amount than the waste portions 176a and 176b shown in FIG. That is, the production of the integrated sealing material is wasteful.

  Although illustration is omitted, even when a mold is prepared to produce a sealing material, the production of the integrated sealing material 99a is often more expensive than the production of the sealing materials 100 and 100a. This is because it is necessary to use a large mold for manufacturing the integrated sealing material 99a. Large mold manufacturing is often more costly than manufacturing multiple small molds. For one thing, the cost of manufacturing the large mold itself is often more expensive than manufacturing multiple smaller ones. Furthermore, when a sealing material is manufactured using a large mold, unevenness tends to occur when the material is filled in the mold. Therefore, the manufacturing of the sealing material using a large mold has a high probability that the manufacturing yield decreases. A decrease in yield means an increase in manufacturing cost.

  Next, a case using the sealing material 100a shown in FIG. 2 will be described.

  The sealing material 100a shown in FIG. 2 is used by being sandwiched between two parts constituting the casing.

  FIG. 6 is a conceptual diagram illustrating a casing first portion 11a that is an example of a first portion of a casing to which the sealing material 100a illustrated in FIG. 2 can be applied. FIG. 6A is a diagram assuming a case where the housing first part 11a is viewed from the side with the opening. FIG. 6B is a cross-sectional view assuming a case where the housing first part 11a is cut along a line 199h shown in FIG. 6A. FIG. 6C is a cross-sectional view assuming a case where the housing first part 11a is cut along a line 199i shown in FIG. 6A.

  The housing first part 11a includes an opening 191a on one surface of the housing first part 11a, and a cavity 178a inside the housing first part 11a. And the housing | casing 1st part 11a is equipped with the 1st housing | casing surface 192a in the self surface provided with the opening 191a. The first housing surface 192a is a surface on which the sealing material 100a is assumed to be sandwiched between the second housing surface of the housing second part described later and itself.

  FIG. 7 is a conceptual diagram illustrating a housing second portion 12a that is a first example of a second portion of the housing to which the sealing material 100a illustrated in FIG. 2 can be applied. Fig.7 (a) is the figure which assumed the case where the largest surface with which the housing | casing 2nd part 12a is equipped with the housing | casing 2nd part 12a was seen. FIG. 7B is a cross-sectional view assuming a case where the housing second portion 12a is cut along a line 199j shown in FIG. FIG.7 (c) is sectional drawing supposing the case where the housing | casing 2nd part 12a is cut | disconnected by the line | wire 199k represented to Fig.7 (a).

  As shown in FIGS. 7A to 7C, the housing second portion 12a is plate-shaped. And the housing | casing 2nd part 12a is provided with the 2nd housing | casing surface 189a. The second housing surface 189a is a surface on which the sealing material 100a is assumed to be sandwiched between the first housing surface 192a of the housing first portion 11a and the self.

  FIG. 8 is a conceptual diagram showing a housing second portion 12b that is an example (part 2) of the second portion of the housing to which the sealing material 100a shown in FIG. 2 can be applied. FIG. 8A is a diagram assuming a case where the housing second portion 12b is viewed from the opening side. FIG. 8B is a cross-sectional view assuming a case where the housing second portion 12b is cut along a line 199l shown in FIG. FIG. 8C is a cross-sectional view assuming a case where the housing second portion 12b is cut along a line 199m shown in FIG. 8A.

  The housing second part 12b includes an opening 191b on one surface of the housing 12b, and a cavity 178b on the inside of the housing second portion 12b. And the housing | casing 2nd part 12b equips the self surface provided with the opening 191b with the 2nd housing | casing surface 189b. The second housing surface 189b is a surface on which the sealing material 100a is assumed to be sandwiched between the first housing surface 192a of the housing first part 11a and the self.

  9 shows a case 1a that is an example of a case using the case first part 11a shown in FIG. 6, the case second part 12a shown in FIG. 7, and the sealing material 100a shown in FIG. It is a conceptual diagram showing a structure. FIG. 9A is a diagram assuming a case where the housing 1a is viewed from the housing second portion 12a side. FIG. 9B is a cross-sectional view assuming that the housing 1a is cut along a line 199h shown in FIG. 9A. FIG. 9C is a cross-sectional view assuming that the housing 1a is cut along a line 199i shown in FIG. 9A.

  As shown in FIGS. 9A to 9C, the first part 111a, the second part 121a, and the third part 131a of the sealing material 100a are connected to the first housing surface 192a of the housing first part 11a. It is installed between the second housing surface 189a of the body second part 12a. And the housing | casing 1st part 11a and the housing | casing 2nd part 12a are being fixed, with the force of the direction in which the 1st housing | casing surface 192a and the 2nd housing | casing surface 189a approach is applied. The housing first part 11a and the housing second part 12a are fixed by, for example, providing holes at positions 188a to 188d shown in FIG. 9A of the housing second part 12a and using the holes. And tightening with screws and nuts (not shown).

  6 to 9, the case 1a having a rectangular parallelepiped shape in the combined state has been described as an example. However, the shape of the housing is arbitrary as long as the sealing material of the present embodiment is sandwiched between the first housing surface of the first housing portion and the second housing surface of the second housing portion. Further, the shapes of the first housing surface and the second housing surface are arbitrary as long as the sealing material of the present embodiment is sandwiched between the first housing surface and the second housing surface without any gap. Here, “without a gap” means that the first housing surface, the sealing material, the sealing material, and the second material are located at any position where the sealing material of the present embodiment is sandwiched between the first housing surface and the second housing surface. This means that there is no gap between the housing surface. Accordingly, a gap may be formed between the first housing surface and the second housing surface at a position where the sealing material is not sandwiched.

  Next, the waterproof effect with respect to the water which falls from upper direction of the housing | casing 1a represented in FIG. 9 is demonstrated. The water descending from above is, for example, rain.

  FIG. 10 is an image diagram illustrating a state in which the water 197a descending from above is descending with respect to the housing 1a.

  As shown in FIG. 10, the water 197a falls on the upper surface 184a of the housing 1a.

  FIG. 11 is an image diagram illustrating a state in which water 197a that has fallen on the upper surface 184a of the housing 1a flows.

  The water 197a that has fallen on the upper surface 184a of the casing 1a flows on the upper surface 184a as water 197b and 197c shown in FIG. 11A and water 197m and 197n shown in FIG. 11B. Thereafter, the water 197b, 197c, 197m, and 197n travel downward as water 197d and 197e shown in FIG. 11A and water 197o and 197p shown in FIG.

  FIG. 12 is an image diagram showing the flow of water in the portion 195a shown in FIG.

  Although the above-mentioned water 197d goes downward, a part of the water 197d wraps around the lower end 187a as water 197f and may enter the gap 196a. Here, the gap 196a is a gap formed between the hanging part lower end 187a and the second part upper end 186a. However, since gravity acts on the water 197f in the direction of the arrow 194a, the way of entering is not large. Therefore, the probability that the water 197f reaches the second portion upper end 186a is low. Even if the water 197f gets over the second part upper end 186a and enters the inside of the housing 1a (the cavity 178a shown in FIG. 6), the amount of water 197f is small and the speed of entering the water 197f is small. The probability of adversely affecting is low.

  The description of the flow of water in the portion 195b shown in FIG.

  FIG. 13 is an image diagram showing the flow of water in the portion 195c shown in FIG.

  Although the above-mentioned water 197g goes downward, a part of the water 197g wraps around the housing second part lower end 183a as water 197h and may enter the gap 196b. Here, the gap 196b is a gap formed between the housing second part lower end 183a and the end part 182a of the housing first part 11a. However, since gravity acts on the water 197h in the direction of the arrow 194a, the way of entering is not large. Therefore, the probability that the water 197h reaches the end 182a is low. Further, even if the water 197h gets over the end portion 182a and enters the inside of the housing 1a (the cavity 178a shown in FIG. 6), the amount of water 197h is small and the entering speed is small, so the water 197h has an adverse effect on the inside of the cavity. The probability of affecting is low.

  Next, variations in how the sealing material 100 shown in FIG. 1 is installed in the housing will be described.

  FIG. 14 is a conceptual diagram showing a sealing material 100b, which is a first variation of the sealing material 100 shown in FIG.

  The hanging part 113aa and the second part 121a are in contact with each other on the surface 193a.

  Further, the hanging part 113ab and the third part 131a are in contact with each other on the surface 193b.

  As described above, since the hanging part 113aa and the second part 121a are in contact with each other at the surface 193c, the sealing material 100b does not have a gap corresponding to the gap 196a shown in FIG. Therefore, water does not enter the inside of the housing from between the hanging part 113aa and the second part 121a.

  Further, as described above, since the hanging part 113ab and the third part 131a are in contact with each other at the surface 193d, the sealing material 100b has no gap corresponding to the gap 196a shown in FIG. . Therefore, water does not enter the inside of the housing from between the hanging part 113ab and the third part 131a.

  However, immediately after the sealing material 100b is installed in the housing, even if there is no clearance corresponding to the clearance 196a shown in FIG. There can be. The gap is a gap generated between the hanging part 113aa and the second part 121a or between the hanging part 113ab and the third part 131a. However, when a gap is generated between the hanging part 113aa and the second part 121a or between the hanging part 113ab and the third part 131a, the sealing material is only similar to the sealing material 100a shown in FIG. Absent. Therefore, the sealing material in which the gap is generated is rare in the case where water enters the casing by the same description as that described with reference to FIGS.

  FIG. 15 is a conceptual diagram showing a sealing material 100c which is a second variation of the sealing material 100 shown in FIG. 1 after being installed in the housing.

  The hanging part 113aa and the second part 121a are in contact with each other at the surface 193c. The upper part 112a and the second part 121a are in contact with each other at the surface 193e.

  Further, the hanging portion 113ab and the third portion 131a are in contact with each other at the surface 193d. The upper part 112a and the third part 131a are in contact with each other at the surface 193f.

  As described above, the sealing material 100c is in contact with the hanging part 113aa and the second part 121a, and the upper part 112a and the second part 121a. There is no gap corresponding to 196a. Therefore, water does not enter the inside of the housing 1a from between the hanging part 113aa and the second part 121a. Even if a gap occurs only in one of the surface 193c and the surface 193e due to deformation of the first part 111a and the second part 121a, it does not become a gap connected to the inside of the housing. The reason why the gap does not connect to the inside of the housing is that the sealing material 100c is further in contact with the first part 111a and the second part 121a on both the surface 193c and the surface 193e. Therefore, in the sealing material 100c, there is a possibility that, as compared with the sealing material 100b illustrated in FIG. Is low. Therefore, the sealing material 100c can reduce the probability that water enters the inside of the housing due to deformation of the housing and the sealing material 100c after installation.

  Immediately after the sealing material 100c is installed in the housing, even if there is no space corresponding to the space 196a shown in FIG. . The gap is between both the hanging part 113aa and the second part 121a and between the upper part 112a and the second part 121a, or between the hanging part 113ab and the third part 131a, and between the upper part 112a and the third part 131a. Is a gap that occurs in both. However, when such a gap occurs, the sealing material is only similar to the sealing material 100a shown in FIG. Therefore, the sealing material in which the gap is generated is rare in the case where water enters the casing by the same description as that described with reference to FIGS.

  Next, an example of the shape options of the sealing material 100 illustrated in FIG. 1 and the sealing material 100a after being installed in the housing illustrated in FIG. 2 will be described.

  FIG. 16 is a conceptual diagram showing an example of options of the cross-sectional shape of the sealing material 100 shown in FIG. The cross section shown in FIG. 16 is a cross section before the sealing material 100 is installed in the housing. FIG. 16 assumes that the first part 111a shown in FIG. 1 is cut by a line 199a, 199b or 199c, the second part 121a is cut by a line 199d, or the third part 131a is cut by a line 199e. Represents a cross-section of the case.

  As shown in FIGS. 16A to 16F, the cross-sectional shape of the first part 111a, the second part 121a, or the third part 131a can be selected from various shapes.

  Further, two or more cross-sectional shapes of the first part 111a, the second part 121a, and the third part 131a may be different. Furthermore, the cross-sectional shape may be different depending on the portion of each of the first part 111a, the second part 121a, and the third part 131a.

  FIG. 17 is a conceptual diagram showing an example of the shape options of the upper part 112a of the first part 111a shown in FIG. FIG. 17 shows the shape of the upper part 112a when the first part 111a is installed in the housing.

  As shown in FIGS. 17A to 17F, the shape of the upper portion 112a can be selected from various shapes.

  FIG. 18 is a conceptual diagram illustrating an example of options for the shape of the hanging portion 113aa illustrated in FIG. FIG. 18 shows the shape of the hanging part 113aa when the first part 111a is installed in the housing.

  18 (a) to 18 (f) are variations of the shape of the drooping portion that hangs substantially downward. 18 (g) to 18 (i) are variations of the shape of the hanging portion that hangs down in a direction deviated from the downward direction.

  As shown in FIGS. 18A to 18I, the shape of the hanging portion 113aa can be selected from various shapes as long as it is a shape that hangs downward while being installed in the housing.

  The shape of the hanging part 113ab can also be selected from various shapes including a shape similar to the shape shown in FIG. 18 as long as it is a shape that hangs downward in a state of being installed in the housing.

[effect]
The sealing material of the present embodiment, when installed in the housing, is a first portion of the housing (housing first portion 11a) and a second portion of the housing (housing second portion 12a (or 12b). ). Accordingly, water that falls on the housing from above the housing is restrained by the first portion of the housing and the second portion of the housing from the side of the sealing material of the present embodiment (housing 1a). ) Is rarely inside.

  On the other hand, when the sealing material of the present embodiment is installed in the housing, the first portion (first portion 111a) of the sealing material of the present embodiment is the first hanging portion (the hanging portion 113aa) and the second hanging portion. And a hanging part (the hanging part 113ab). And the part other than the 1st part of the sealing material of this embodiment is provided with the 1st side part (2nd part 121a) and the 2nd side part (3rd part 131a). And the upper end (second part upper end 186a) of the first side part is above the lower end (lower part lower end 187a) of the first hanging part. The upper end of the second side portion (third portion upper end 185a) is above the lower end of the second drooping portion (lowering portion lower end 187b).

  The water that falls on the housing from above the housing passes through between the first portion of the sealing material of the present embodiment and the portion other than the first portion of the sealing material of the present embodiment, and enters the interior of the housing. Assume that you enter. In that case, water gets over the upper end of the first side part against the gravity from the lower end of the first hanging part and enters the inside of the casing. Alternatively, the water enters the inside of the housing over the upper end of the second side part against the gravity from the lower end of the second hanging part. Therefore, the probability that water will enter the inside of the housing is low.

  Furthermore, the sealing material of this embodiment is comprised from the some isolate | separated part, and is used combining a some part. Each of the plurality of portions is smaller than the integral sealant. It is often cheaper to create multiple sealant portions for use in combination than to create one large sealant. Therefore, the sealing material of this embodiment may be able to be produced at a lower cost than a single sealing material used without being combined.

  That is, as for the sealing material of this embodiment, the case to which the sealing material of the present invention is applied has a waterproof function necessary for water descending from above, and the sealing material of the present invention is manufactured at low cost. May be possible.

  FIG. 23 is a conceptual diagram showing the configuration of a sealing material 100x, which is the minimum configuration of the sealing material of the present invention. An arrow 194x shown in FIG. 23 represents the direction in which the attractive force works.

  It is assumed that the sealing material 100x is used in an environment where attractive force represented by an arrow 194x works. And it is assumed that the sealing material 100x is installed between the 1st surface of the 1st part of a housing | casing, and the 2nd surface of the 2nd part of the said housing | casing. Further, the sealing material 100x is used by fixing the first part and the second part in a state where a force is applied in a direction in which the first part and the second part are brought closer to each other. Is assumed.

  The sealing material 100x is a first part 111x as a first part, and other parts other than the first part 111x separated from the first part 111x (only the first side part 181x and the second side part 181y are illustrated. .).

  The first part 111x includes an upper part 112x and a first hanging part 113x that is formed continuously with the upper part 112x or connected to the upper part 112x without a gap and hangs down in the direction in which an attractive force acts. The first part 111x further includes a second hanging part 113y that is formed continuously with the upper part 112x or connected to the upper part 112x without a gap and hangs down in a direction in which an attractive force acts.

  The other portion includes a first side 181x that is a first side and a second side 181y that is a second side.

  The lower end 187x of the drooping portion 113x is positioned in the direction in which an attractive force acts with respect to the upper end 179x of the first side portion 181x. The lower end 187y of the drooping portion 113y is positioned in a direction in which an attractive force acts on the upper end 179x of the second side portion 181y.

  The shapes of the upper part 112x and the hanging parts 113x and 113y are arbitrary as long as the above conditions are satisfied.

  In the above-described configuration, the lower end 187x of the sagging portion 113x of the first portion is positioned in a direction in which an attractive force acts on the upper end 179x of the first side portion 181x of the second portion. Further, in the above configuration, the lower end 187y of the hanging part 113y of the second part is positioned in a direction in which an attractive force acts on the upper end 179y of the second side part 181y of the second part. Further, the sealing material 100x is used by fixing the first part and the second part in a state where a force is applied in a direction in which the first part and the second part are brought closer to each other. Therefore, in order for the descending liquid to enter the casing in which the sealing material 100x is installed from the gap between the drooping portion 113x and the first side portion 181x, the liquid counters the attractive force acting on the first side portion 181x. You have to get over the top edge 179x. In addition, in order for the descending liquid to enter the casing in which the sealing material 100x is installed from the gap between the drooping portion 113y and the second side portion 181y, the liquid is against the attractive force acting on the second side portion 181y. You have to get over the top edge 179y. Therefore, the probability that the liquid gets over the upper end 179x and the upper end 179y and enters the casing in which the sealing material 100x is installed is low. Even if the liquid gets over the upper end 179x or the upper end 179y and enters the casing in which the sealing material 100x is installed, the amount of the liquid entering is small. Further, the sealing material 100x is separated into two parts of the first part. Therefore, the manufacture of the sealing material 100x may be cheaper than the manufacture of an integrated sealing material having a similar size and shape similar to the sealing material 100x.

  As described above, the sealing material 100x has the effects described in the section “Effects of the Invention” due to the above configuration.

  The present invention has been described above with reference to preferred embodiments. However, the present invention is not necessarily limited to the above embodiments, and various modifications can be made within the scope of the technical idea.

  Moreover, although a part or all of said embodiment can be described also as the following additional remarks, it is not restricted to the following.
