Abstract
Description
[Technical field]
[0001] The present invention relates to a water drainage member provided on a door glass of a vehicle. [Background technology]
[0002] Conventionally, as shown in Fig. 6, a vehicle door D has a drain hole H at the bottom to drain intruding water W from the vehicle door interior S to the outside when the water adhering to the door glass FG runs down the outer surface and inadvertently infiltrates into the vehicle door interior S. Fig. 6 shows the internal structure of the vehicle door.
[0003] Inside the vehicle door S, door built-in parts P such as a door glass lifting device and a door lock device are arranged in a complex manner at predetermined positions below the lower edge FG1 of the door glass FG.
[0004] Water W that infiltrates into the interior S of a vehicle door flows down the door glass FG and collects in the lower front and rear corners of the door frame DF and the door glass FG, and in most cases enters through the front and rear gaps between the molding along the waistline WL and the door glass FG.
[0005] That is, as shown in FIG. 6, the intruding water W forms a flow path R along the lower edge FG1 of the door glass FG exposed at the upper side of the vehicle door interior S, and falls toward the door built-in component P located below without losing its flow force, thereby interfering with the door built-in component P and causing defects such as corrosion and deterioration of the door built-in component P and electric leakage.
[0006] In order to prevent such water damage to the built-in door components, various water-draining technologies have been proposed, such as changing the shape of the lower edge of the glass (see, for example, Patent Document 1) or adding a long, thin gutter section around the entire lower edge of the glass (see, for example, Patent Document 2), to change the position from which water enters from the lower edge of the glass and falls to a position where it will not get wet and interfere with the built-in door components. [Prior art documents] [Patent documents]
[0007] [Patent Document 1] Japanese Utility Model Application Publication No. 6-49130 [Patent Document 2] JP 2004-324350 A Summary of the Invention [Problem to be solved by the invention]
[0008] However, the above-mentioned conventional water draining technology has a problem in that it is necessary to change the shape of the door glass or design and install a large gutter portion each time in order to accommodate the different vehicle door shapes for each vehicle body and to avoid interference with other vehicle door parts within the limited space inside the vehicle door.
[0009] That is, the above-mentioned conventional technology has problems such as unnecessarily increasing the labor required for attaching the parts, such as changing the shape of the door glass and designing the gutter part to suit each individual door glass, and also increasing the cost. Furthermore, there is a problem that it cannot be easily retrofitted to existing door glass of a vehicle that is already in circulation.
[0010] The present invention has been made in consideration of the above circumstances, and aims to provide a water-draining member that can be easily retrofitted to existing door glass, reducing the effort required for installing the member as much as possible, and reducing costs, and that can drain and drain infiltrating water flowing along the lower edge of the door glass at a position that does not interfere with the wetting of the door's built-in components, thereby preventing water damage to the door's built-in components. [Means for solving the problem]
[0011] In order to solve the above-mentioned problems, the present invention provides (1) a water-draining member that is installed in the middle of a water flow path formed along the extension direction of the lower edge of a vehicle door glass, and allows the flowing water to fall to a predetermined position inside the vehicle door, the water-draining member comprising: a support extending along the water flow path and fixed to the lower edge of the glass; and a water-draining body provided on the support and closely attached to the lower edge of the glass from below via the support, the water-draining body having a predetermined thickness, abutting against both side sides of the lower edge of the glass while in close contact with the lower edge of the glass, and protruding outward from both side sides to face the upstream side of the water-draining path and blocking the flowing water to allow the water to fall.
[0012] The drainage member according to the present invention is characterized in the following points (2) to (5). (2) The water-draining body is made of an elastic block material having an approximately rectangular shape, and one side of the square is used as the water-draining surface. (3) The support body has a drainage hole to allow water that overflows the drain body to drain. (4) The support body has an installation portion for installing the water dripping body on the upstream side of the water flow path, and a fixing portion for fixing it to the lower edge portion of the glass on the downstream side of the water flow path. (5) The support body comprises a bottom wall facing the underside of the lower edge of the glass, and a side wall rising from one side edge of the bottom wall and facing at least one of the inner and outer surfaces of the lower edge of the glass, the bottom wall having the installation portion and the water drainage hole, and the one side wall having the fixing portion. Effect of the Invention
[0013] According to the invention of claim 1, a water-draining member is installed in the middle of a water flow path formed along the extension direction of the lower edge of a door glass for a vehicle, and causes the flowing water to fall to a predetermined position inside the vehicle door, the water-draining member comprising: a support body extending along the water flow path and fixed to the lower edge of the glass; and a water-draining body provided on the support body and closely attached to the lower edge of the glass from below via the support body, the water-draining body having a predetermined thickness and abutting both sides of the lower edge of the glass in a closely attached state to the lower edge of the glass, and protruding outward from both sides to face the upstream side of the water flow path, thereby blocking the flowing water and causing the water to fall. This makes it possible to easily retrofit the member to an existing door glass, thereby reducing the effort required for installing the member as much as possible and reducing costs, and has the effect of draining and draining intruding water flowing along the lower edge of the door glass at a position where it does not interfere with the water wetting of the door built-in components, thereby preventing water damage to the door built-in components from occurring.
[0014] Specifically, a water cutter is arranged on the lower edge of the glass (hereinafter simply referred to as the non-wet area) facing an area inside the vehicle door where falling water does not cover and interfere with the door's built-in components (hereinafter simply referred to as the non-wet area), so that the water cutter surface is oriented on the upstream side of the running water path. The water cutter surface oriented in this way functions as a water drop surface that receives and blocks the running water, attenuates the flow force, and changes the position of the water falling into the door interior.
[0015] In other words, the flowing water is forcibly blocked at a non-wet area midway along the water path at the lower edge of the glass, allowing it to fall precisely to a non-wet area below, thereby preventing as much water damage as possible, such as corrosion and deterioration of the door's built-in components due to them getting wet and damage to the electrical system.
[0016] In addition, the prevention of water damage to built-in door components can be achieved through a simple retrofitting process that simply requires pinpointing and attaching the product to a non-water-exposed area of the lower edge of the existing door glass of vehicles on the market without changing the shape of the door glass or surrounding components, thereby improving the ease of installation and significantly reducing costs.
[0017] In addition, according to the invention of claim 2, the water-draining body is made of an elastic block material having an approximately rectangular shape, and one side of the square is made into the water-draining surface portion, so that it elastically deforms while in close contact with the lower edge portion of the glass via the support body, and can be watertightly pressed against both sides of the lower edge portion without any gaps, thereby reliably generating the water-draining function of blocking running water and draining it away at the water-draining surface portion.
[0018] In addition, the water dripper can be attached to the lower edge of the glass without having to be molded each time to fit various shapes of the lower edge, which further improves the workability of installing the parts and reduces the cost of parts.
[0019] Furthermore, according to the invention of claim 3, the support body has a drainage hole for draining water that overflows the drain body. Therefore, when the flow rate of water in the water path is large or the flow force is strong and the water overflows the drain body, the overflowing water can be drained through the drainage hole, thereby realizing a so-called two-stage drainage by the drainage surface portion and the drainage hole.
[0020] In addition, according to the invention of claim 4, the support body has an installation portion for installing the water cutter on the upstream side of the flowing water path, and a fixing portion for fixing it to the lower edge of the glass on the downstream side of the flowing water path.Since the fixing portion is positioned downstream of the flowing water path of the lower edge of the glass than the water cutter installed at the installation portion, the fixing portion can be kept away from the flowing water to prevent it from becoming wet, and this has the effect of stabilizing the fixed state of the water cutter member to the door glass.
[0021] According to the invention of claim 5, the support includes a bottom wall facing the underside of the lower edge of the glass, and one side wall rising from one edge of the bottom wall and facing at least one of the inner and outer surfaces of the lower edge of the glass, the bottom wall having the installation portion and the water drainage hole, and the one side wall having the fixing portion, so that the support can have a simple shape consisting of the bottom wall and the one side wall and the material cost can be reduced as much as possible. In addition, since the fixing portion is fixed to one of the inner and outer surfaces of the lower edge of the glass, not only can the possibility of the fixing portion being wetted by water be further reduced, but also the positioning of the installation can be easily determined, and the installation workability can be further improved.

[0023] The gist of the present invention is to provide a water-draining member that is installed in the middle of a water flow path formed along the extension direction of the lower edge of the glass of a vehicle door glass, and allows the flowing water to fall to a predetermined position inside the vehicle door, the water-draining member comprising: a support body that extends along the water flow path and is fixed to the lower edge of the glass; and a water-draining body that is provided on the support body and is closely attached to the lower edge of the glass from below via the support body, the water-draining body having a predetermined thickness, abutting against both side sides of the lower edge of the glass while in close contact with the lower edge of the glass, and protruding outward from both side sides to face the upstream side of the water flow path and block the flowing water to allow it to fall.
[0024] The water draining body is made of a substantially rectangular elastic block material, and one side of the rectangle is used as the water draining surface.
[0025] The support body is also characterized by having drainage holes for draining water that overflows the drain body.
[0026] The support body is further characterized in having an installation portion for installing the water dripping body on the upstream side of the water flow path, and a fixing portion for fixing the water dripping body to the lower edge portion of the glass on the downstream side of the water flow path.
[0027] The support body further comprises a bottom wall facing the underside of the lower edge of the glass, and a side wall rising from one side edge of the bottom wall and facing at least one of the inner and outer surfaces of the lower edge of the glass, the bottom wall having the installation portion and the water drainage hole, and the one side wall having the fixing portion.
[0028] Hereinafter, an embodiment of the drainage member according to the present invention will be described. Figures 1(a) and 1(b) are respectively a rear perspective view and a plan view showing the configuration of the drainage member, Figures 2(a) and 2(b) are respectively a schematic side view showing the attachment of the drainage member to the door glass and a side view showing the configuration of the drainage member, Figures 3(a) and 3(b) are respectively a schematic perspective view showing the attachment of the drainage member to the door glass and a front perspective view showing the configuration of the drainage member, Figure 4 is a schematic side view explaining the drainage function of the drainage member attached to the lower edge of the door glass, and Figure 5 is a schematic partially enlarged side view explaining the drainage function of the drainage member attached to the lower edge of the door glass.
[0029] In the following description, unless otherwise specified, the upper and lower sides are the upper and lower sides of the vehicle, the front and rear sides are the front and rear sides of the vehicle, and the inside and outside are the inside and outside of the vehicle. In the following embodiment, the configuration in which the sensor is attached to the door glass of the front door on the right side of the vehicle is described as an example, but it goes without saying that the sensor can also be attached to the door glass of the front door on the left side of the vehicle, or the door glass of the rear door on the left and right sides of the vehicle.
[0030] As shown in Figure 6, the door glass FG of a commonly used vehicle door D has a lower edge FG1 of the glass exposed at the upper side of the vehicle door interior S, which is formed in a downwardly convex shape when viewed from the side, and has front and rear end portions FG2, FG3 with chamfered front and rear corners, and a straight portion FG4 extending in a substantially straight line between the front and rear end portions FG2, FG3.
[0031] In the door glass FG according to the present embodiment, front and rear ends FG2, FG3 of the lower edge FG1 of the glass are chamfered into a boss shape.
[0032] Further, inside the vehicle door S, as shown in FIG. 6, there are disposed door built-in parts P such as a glass lifting device connected to the straight portion FG13 of the lower edge FG1 of the door glass FG and consisting of a regulator P1 for raising and lowering the door glass FG and a motor P2 for driving the regulator P1 up and down.
[0033] This door-mounted component P is disposed in the central portion of the vehicle door interior S at a lower position corresponding to most of the front-to-rear direction of the lower glass edge FG1 of the door glass FG, and may be exposed to intruding water W that runs down the exposed lower glass edge FG1 in the vehicle door interior S.
[0034] In other words, the non-wet area S1 of the vehicle door interior S, where the falling water moves away from the arrangement position of the door-integrated component P and the door-integrated component P is not covered with water, is a space portion of the vehicle door interior S where the door-integrated component P is not arranged.
[0035] In such a structure of the interior S of a vehicle door, the water drainage member A of this embodiment is installed in the middle of a flow path R along the extension direction of the lower edge FG1 of the door glass FG of the vehicle door D, as shown in Figure 4, and is configured to direct the flowing water to a predetermined position in the interior S of the vehicle door S, i.e., the non-watered area S1.
[0036] The flow path R of the intruding water W tends to be formed along the chamfered and inclined front and rear ends FG2, FG3 at the bottom edge FG1 of the glass. In other words, the middle part of the flow path R, which is the location where the water draining member A is disposed, is the bottom edge FG10 of the glass that functions as a non-wet area facing the non-wet area S1 at the bottom edge FG1 of the glass, and is a part that includes at least one end of the front end FG2 or the rear end FG3 of the bottom edge FG1 of the glass.
[0037] The lower edge portion FG10 of the glass, which functions as a non-wet area in this embodiment, is a front bent angle portion formed by a front end portion FG2 that is chamfered and slopes downward toward the straight portion FG4, and the front end of the straight portion FG4, or a rear bent angle portion formed by a rear end portion FG3 that is chamfered and slopes downward toward the straight portion FG4, and the rear end of the straight portion FG4.
[0038] In other words, the water-draining member A of the present invention is intended to prevent water damage to door internal components by a simple retrofitting process that requires only pinpoint attachment to a non-water-exposed portion of the lower edge FG1 of the glass, i.e., the lower edge FG10 of the glass, without changing the shape of the door glass or surrounding components.
[0039] As shown in Figures 1(a) to 2(b), the draining member A comprises a support 10 that extends along the running water path R and is fixed to the lower edge portion FG10 of the glass, and a draining body 20 that is provided on the support 10 and is in close contact with the lower edge portion FG10 of the glass from below via the support 10. As shown in Figure 1(b), the draining member A is configured so that the lower edge portion FG10 of the glass is located in the widthwise center of the support 10 and the draining body 20 in a plan view.
[0040] As shown in Figures 3(a) and 3(b), the water-cutting body 20 has a predetermined thickness and is in close contact with the inner and outer surfaces FG10a, FG10b of the lower edge portion FG10 of the glass (front end portion FG2) while protruding outward from the inner and outer surfaces FG10a, FG10b, thereby forming a water-cutting surface portion 21 that faces the upstream side of the water flow path R and blocks the flowing water to allow it to drain.
[0041] That is, the water skirting body 20 is made of a substantially rectangular block material, and is formed into a water skirting surface 21 having a concave cross section in close contact with the glass lower edge portion FG10 at the center in the width direction, and the concave end surface portion faces the door frame DF side (the upstream side of the running water path R). For example, such a water skirting body 20 may have a fitting recess formed along the front-rear direction at the center in the width direction, into which the glass lower edge portion FG10 is inserted.
[0042] The water drainage surface 21 in this embodiment is made of an elastic block material having an approximately rectangular shape, which elastically deforms to become concave when pressed against the lower edge portion FG10 of the glass, and forms a rectangular side portion of the water drainage surface 21 that corresponds to the concave front end surface.
[0043] As the elastic block material, a resin material having flexibility, malleability and porosity, such as EPT, can be used, which can be impregnated with a certain amount of water and retain it, and when the water retention capacity is exceeded, one end surface portion oriented upstream of the flow path R can function as a water-draining surface portion 21.
[0044] As a result, the water-skirting body 20 is watertightly pressed against the inner and outer surfaces FG10a, FG10b of the glass bottom edge FG10 without any gaps, generating a strong wrapping force, and in this pressed state, the water-skirting surface 21 can reliably perform the water-skirting function of blocking running water and draining it away. In addition, after the water-skirting member A is installed, it is flexible and can absorb vibrations of the vehicle and prevent misalignment. In addition, the water-skirting body 20 can be adapted to various glass bottom edges FG1 without having to be molded each time, further improving the workability of installing the member, and reducing the cost of the member.
[0045] The support body 10 is interposed between the door glass FG and the water-skirting body 20 to support the pressed state of the water-skirting body 20 against the lower edge portion FG10 of the glass, and is basically formed along the front-to-rear shape of the lower edge portion FG10 of the glass to which the water-skirting member A is attached, i.e., along the flow path R.
[0046] The support 10 has drainage holes 30 at predetermined positions for allowing water that overflows the drain body 20 to drain, as shown in Figs. 1(a) to 3(b).
[0047] Details will be described later, but the water drainage hole 30 is adjacent to the water drainage body 20 in the extension direction of the support body 10, and is formed in a part facing the downstream side of the flow path R rather than the part where the water drainage body 20 facing the upstream side of the flow path R is provided.
[0048] As a result, as shown in Figures 4 and 5, when the flow rate of water in the water path R is large or the flow force is strong, causing the intruding water W to overflow the water-cutting body 20, the overflowing water falls and is cut off through the water-cutting hole 30, thereby realizing a so-called two-stage water-cutting by the water-cutting surface portion 21 and the water-cutting hole 30.
[0049] The support 10 also has an installation portion 11 for installing the water dripping body 20 on the upstream side of the water flow path R, and a fixing portion 12 for fixing it to the lower edge portion FG10 of the glass on the downstream side of the water flow path R.
[0050] As shown in Figure 3 (b), the installation portion 11 has an upper surface that faces the bottom surface 20a of the water-draining body 20, and is formed on the support 10 as a cut portion 11a on the upper surface that fixes the water-draining body 20 via a fixing means 40.
[0051] The cut piece portion 11a is a plate-shaped portion with approximately the same surface area as the bottom surface of the water-skirting body 20, and is formed to protrude horizontally to one side from the lower end of the support piece portion 11b described later as shown in Figure 3(b).When the water-skirting body 20 is placed on its upper surface, the front and rear end faces are formed to be flush with the front and rear end faces of the water-skirting body 20, as shown in Figures 1(b) to 2(b).
[0052] In other words, when the water-draining body 20 is placed and fixed on the piece portion 11a serving as the installation portion 11 protruding from the fixed portion 12 toward the upstream side of the flow path R, the front end face of one side is flush with the front end face of the piece portion 11a, and together with the front end face of the piece portion 11a, forms a water-draining surface portion 21 oriented toward the upstream side of the flow path R.
[0053] In other words, the support body 10 is configured such that, with the water drain hole 30 as a boundary, the tip end thereof serves as an installation portion 11 for installing the water drain body 20, which has a thin and wide portion corresponding to the upstream side of the water flow path R in the glass lower edge portion FG10, and the base end thereof serves as a fixing portion 12 for fixing to the glass lower edge portion FG10, which has a thick and narrow portion corresponding to the upstream side of the water flow path R in the glass lower edge portion FG10.
[0054] Specifically, as shown in Figure 1 (b), the support body 10 is configured such that, in a plan view, the installation portion 11 is positioned facing the upstream side of the running water path R, with the water drainage hole 30 as the boundary, and the support piece portion 11b as a thin portion on one side wall 14.
[0055] In addition, the support body 10 is configured such that, when viewed in a plan view, a narrow portion that is narrower than the cut piece portion 11a on the bottom side wall 13 and a fixed portion 12 that has a glass-facing surface portion that is thicker than the support piece portion 11b on one side wall 14 are disposed facing the downstream side of the running water path R, with the water drainage hole 30 as the boundary.
[0056] When a molding is attached to the straight portion FG4 of the lower edge FG1 of the glass, one side wall 14 of the support 10 is cut out to the thickness of the molding to correspond to the end of the molding, and one side of the molding fitting groove serves as the glass-facing surface, i.e., the fixing portion 12, which is adhered to the molding and fixed to the lower edge FG1 of the glass via the molding.
[0057] As a result, when the water-draining member A is installed on the lower edge portion FG10 of the glass, the lower edge portion FG10 of the glass is positioned along the central part of the width direction of the support body 10, which stabilizes the formation of the water-draining surface portion 21 by pressing the water-draining body 20 against the lower edge portion FG10 of the glass and also stabilizes the fixed state to the lower edge portion FG10 of the glass.
[0058] The fixing portion 12 has one side surface facing one side surface of the glass lower edge portion FG10, and is formed on the support 10 at the same side surface as a glass-facing surface that is fixed to the glass lower edge portion FG10 via fixing means 40.
[0059] The fixing means 40 is not particularly limited as long as it can fix the drip-proof body 20 and the support 10 to the installation portion 11 and the lower edge portion FG10 of the glass, respectively, and may be, for example, a waterproof adhesive or a connecting bolt. The fixing means 40 of this embodiment employs a double-sided tape 41 as an adhesive member that can be attached to a surface.
[0060] As shown in Figure 2(a), the support 10 is configured so that it can be fitted around the lower edge portion FG10 of the glass, by shaping it in a roughly inverted L-shape in cross section and in a manner that conforms to the angular shape of the lower edge portion FG10 of the glass formed by the chamfered front end portion FG2 and the straight portion FG4.
[0061] This makes it easy to position the drainage member A on the lower edge portion FG10 of the glass by positioning the inner corner of the L-shape of the support 10 on the corner of the lower edge portion FG10 of the glass when installing the drainage member A.
[0062] As shown in Figures 1(a) to 4, the support 10 comprises a bottom wall 13 facing the underside of the glass lower edge portion FG10, and one side wall 14 rising from one edge of the bottom wall 13 and facing at least one of the inner and outer surfaces FG10a, FG10b of the glass lower edge portion FG10 (in this embodiment, the outer surface FG10b), with the bottom wall 13 having an installation portion 11 and a water drainage hole 30, and the one side wall 14 having a fixing portion 12.
[0063] As shown in Fig. 2(b), the bottom wall 13 is a thin strip bent in a generally inverted L-shape when viewed from the side, with the plate surface facing up and down. The front end of the bottom wall 13, which corresponds to the upstream side of the running water path R, is a cut-out portion 11a forming the installation portion 11, and the plate surface portion adjacent to the cut-out portion 11a is cut out in the plate width direction in the shape of a rectangular window to form a water drainage hole 30. The width of the bottom wall 13 is at least as long as the thickness of the door glass FG.
[0064] One side wall 14 is a thick band plate bent in a generally inverted L-shape when viewed from the side, and is erected at a right angle at one end of bottom side wall 13 in the width direction with the plate surface facing inward and outward. One side wall 14 forms an opposing surface portion at fixed portion 12, facing the lower edge portion FG10 of the glass, rearward of drain hole 30. Note that the width of one side wall 14 is at least as long as the thickness of drain body 20.
[0065] 1(a) to 5, the front end of the one side wall 14 is formed as a support piece 11b that protrudes from a vertical base end surface serving as a drainage surface 21 (described later) toward the front end side and is connected to the cut piece 11a of the bottom side wall 13 to cantilever the cut piece 11a. In other words, the support body 10 forms the installation portion 11 at the front end by the cut piece 11a of the bottom side wall 13 and the support piece 11b of the one side wall 14.
[0066] Furthermore, the support 10 has a second water drainage surface portion 31 that faces the upstream side of the running water path R at a rear position of the water drainage hole 30, as shown in Figs. 1(a) to 3(b).
[0067] Specifically, the support body 10 has a base end surface from which the support piece portion 11b protrudes forward on one side wall 14 formed into a second water drainage surface portion 31 that is flush with one side of the hole wall of the water drainage hole 30, forming an L-shape when viewed from the end, and the second water drainage surface portion 31 attenuates and blocks the flow of overflow water that has flowed over the water drainage hole 30, making it possible for the water to fall into the water drainage hole 30 on the near side.
[0068] As shown in Figures 2(a) to 3(b), the fixing portion 12 is composed of two parts on one side wall 14 of the support 10: a central fixing portion 12a that faces the approximately central one side surface portion of the front end portion FG2 of the lower end edge FG1 of the glass, and a rear end fixing portion 12b that faces the front end one side surface portion of the straight portion FG4 of the lower end edge FG1 of the glass.
[0069] The support 10 also has a plurality of abutment ribs 15 for making point contact with the underside of the lower edge portion FG10 of the glass, which are formed on the upper surface rearward of the drainage hole 30 and protrude upward at a predetermined interval in the longitudinal direction.
[0070] As shown in Figures 2(a) and 2(b), the abutment rib 15 is semi-cylindrical, extending in the width direction and protruding upward at a predetermined position on the upper surface of the bottom wall 13, and is formed so that the apex of the cylinder makes point contact with the underside surface of the glass lower edge portion FG10.
[0071] The abutment rib 15 is composed of three ribs: a front rib 15a on the front end side at the lower edge portion FG10 of the glass which abuts against the underside of the front end portion FG2, a middle rib 15b near the bent portion which abuts against the underside of the straight portion FG4, and a rear rib 15c on the rear end side.
[0072] This makes it easy to determine the mounting position of the water drainage member A on the lower edge portion FG10 of the glass, even if there is variation in the shape of the lower edge of the door glass FG, by having each abutment rib 15 contact the front end portion FG2 and straight portion FG4 at points.
[0073] In this way, the support body 10 has a tip portion of the L-shaped long side that serves as a drainage functional portion in which the drain body 20 and the drainage holes 30 are arranged adjacent to each other in sequence from the upstream side to the downstream side of the running water path R, and the remaining portion is formed as an attachment and fixing functional portion in which the fixing portion 12 and the abutment rib 15 are formed.
[0074] The water draining member A constructed as described above is attached to the glass lower edge FG10, which is a non-water-exposed portion facing the non-water-exposed area S1 at the glass lower edge FG1, in the following procedure.
[0075] That is, at the lower edge portion FG10 of the glass, the position of the drainage surface portion 21 of the drainage body 20 is aligned via the support body 10 so that it is located in a non-wet position opposite the non-wet area portion S1 below it, relative to the front end portion FG2 and rear end portion FG3, which become the flow path R of the intruding water W.
[0076] Next, as shown in Figure 2(a), while the multiple abutment ribs 15a, 15b, 15c on the bottom side wall 13 of the support 10 are abutted against the underside of the lower edge portion FG10 of the glass, the water-cutting body 20 provided on the installation portion 11 on the front end side of the support 10 is pressed against the underside of the lower edge portion FG10 of the glass, to orient the water-cutting surface portion 21 upstream of the flow path R.
[0077] Next, as shown in FIG. 3(a), the double-sided tape 41 as the fixing means 40 previously attached to the fixing portion 12 is surface-attached to the outer surface FG10b of the door glass FG, thereby completing the attachment work of the water drainage member A.
[0078] In other words, without requiring a complicated installation process, anyone can easily and precisely attach the water draining member A to the lower edge portion FG10 of the glass, which corresponds to the upper position of the non-wet area S1, with a single touch.
[0079] The water-draining member A attached and fixed to the lower edge portion FG10 of the glass in this manner blocks the intruding water W flowing along the water flow path R by the water-draining surface portion 21 of the water-draining body 20, as shown in Figures 4 and 5, and causes the water to fall toward the non-water-covered area portion S1.
[0080] Even if the flow rate of the invading water W in the water flow path R is large, as shown in Fig. 5, the overflowing water that has flowed over the cutter body 20 is drained toward the non-watered area S1 through the cutter holes 30. Since most of the invading water W is drained by the cutter body 20, the amount of overflowing water tends to be small, and the drainage through the cutter holes 30 is sufficient to handle the situation.
[0081] Furthermore, even if the flow rate of the invading water W in the flow path R is large and the flow force is strong, the overflowing water will hit the second water drainage surface, be blocked, and be guided to fall into the water drainage hole 30, so that the invading water W is effectively drained into the non-watered area S1.
[0082] In this way, the water draining member A changes the water flow path R in the limited space inside the vehicle door S, forcibly guiding the intruding water W to the non-wet area S1, where it is drained through the water draining hole H provided on the inner bottom surface, thereby preventing water damage to door-integrated components P arranged outside the non-wet area S1.
[0083] As described above, the water-draining member of the present invention has the effect of orienting the water-draining surface upstream of the water flow path by arranging the water-draining body at the lower edge of the glass facing the area inside the vehicle door where falling water does not cover and interfere with the door's built-in components, so that the water-draining surface receives and blocks water that enters from the water flow path at the same surface, attenuating the flow force and changing the position of the water falling into the door interior, allowing the water to fall precisely into the non-watered area below, thereby preventing water damage such as corrosion and deterioration of the door's built-in components due to water exposure and damage to the electrical system as much as possible.
[0084] In addition, the prevention of water damage to built-in door components can be achieved through a simple retrofitting process that simply requires pinpointing and attaching the product to a non-water-exposed area of the lower edge of the existing door glass of vehicles on the market without changing the shape of the door glass or surrounding components, thereby improving the ease of installation and significantly reducing costs.
[0085] In addition, the water-cutting body is made of an elastic block material of an approximately rectangular shape, with one side of the square being the water-cutting surface, so that it elastically deforms when in close contact with the lower edge of the glass via the support body, and can be watertightly pressed against both sides of the lower edge without any gaps, which has the effect of reliably generating the water-cutting function of blocking running water at the water-cutting surface and allowing it to drain away.
[0086] In addition, the water dripper can be attached to the lower edge of the glass without having to be molded each time to fit various shapes of the lower edge, which further improves the workability of installing the parts and reduces the cost of parts.
[0087] In addition, the support body is designed to have drainage holes to allow water that overflows the drain body to drain, so that when the flow rate of water in the water path is large or the flow force is strong and the water overflows the drain body, the overflowing water can be drained through the drainage holes, thereby achieving a two-stage drainage system using the drainage surface and the drainage holes.
[0088] In addition, since the support body has an installation section for installing the water cutter on the upstream side of the flowing water path, and a fixing section for fixing it to the lower edge of the glass on the downstream side of the flowing water path, the fixing section is positioned downstream of the flowing water path of the lower edge of the glass than the water cutter installed at the installation section, so that the fixing section can be kept away from the flowing water to prevent the fixing section from becoming wet, and this has the effect of stabilizing the fixed state of the water cutter member to the door glass.
[0089] In addition, the support body includes a bottom wall facing the underside of the bottom edge of the glass, and one side wall rising from one edge of the bottom wall and facing at least one of the inner and outer surfaces of the bottom edge of the glass, and the bottom wall has an installation portion and a water drainage hole, and the one side wall has a fixing portion, so that the support body has a simple shape consisting of the bottom wall and one side wall, and the material cost can be reduced as much as possible. In addition, since the fixing portion is fixed to one of the inner and outer surfaces of the bottom edge of the glass, not only can the possibility of the fixing portion being wetted can be further reduced, but also the positioning of the installation can be easily determined, and the installation workability can be further improved.
[0090] In other words, according to the present invention, it is possible to easily retrofit the device to existing door glass, reducing the effort required for installing the parts as much as possible and reducing costs. It is also possible to drain and drain water that flows along the lower edge of the door glass at a position that does not interfere with the water wetting of the door's internal components, thereby preventing water damage to the door's internal components.
