Abstract
Description
[Technical Field]
[0001] The present invention relates to a mounting structure for a partition weatherstrip that is attached to the periphery of a partition glass attached to the front end of a front door of an automobile and is attached to the mounting portion of a door sash or an outside mirror. [Background technology]
[0002] A known conventional partition weatherstrip mounting structure is described in Patent Document 1 below.
[0003] FIG. 1 is a side view of an automobile front door to which partition weatherstrips of the present invention and the prior art are attached, and FIG. 13 is an exploded perspective view of essential parts showing a cross-section of the prior art partition weatherstrip attachment structure.
[0004] As shown in Figure 1, the partition weatherstrip 30 holds the partition glass 9 at the front end of the window portion of the front door 1 and is arranged in a closed loop around the door body 2, door sash 3, and center sash 4.
[0005] As shown in Figure 13, the partition weatherstrip 30 has a glass holding portion 31 with an approximately U-shaped cross section, into which the peripheral edge of the partition glass 9 is fitted and held on its inner periphery, and the bottom portion 31a of this glass holding portion 31 is attached to a mirror reinforcement (mirror bracket) 32 provided on the vehicle upper side of the door panel for attaching the door mirror.
[0006] The mirror bracket 32 has a strip mounting portion 33 formed by pressing a metal plate, for example, and bent into a crank shape to hold the partition weatherstrip 30 on the inside in the vehicle width direction. The strip mounting portion 33 has a substantially flat strip receiving portion 33a extending along the vehicle width direction, and this strip receiving portion 33a is provided with insertion holes 33b that are substantially rectangular in plan view. The insertion holes 33b are provided at two locations spaced a predetermined distance apart in the vehicle longitudinal direction.
[0007] Meanwhile, two insertion portions 31b to be inserted into the respective insertion holes 33b are protruded from the underside of the bottom portion 31a of the glass holding portion 31. The outer peripheral shape of each insertion portion 31b is formed to be substantially the same as the inner peripheral shape of each insertion hole 33b, and each insertion portion 31b is inserted into each insertion hole 33b from above downward, i.e., vertically.
[0008] Therefore, the partition weatherstrip 30 is positioned and attached to the mirror bracket 18 by inserting the insertion portions 31b into the insertion holes 33b of the mirror bracket 18, respectively. [Prior art documents] [Patent documents]
[0009] [Patent Document 1] Japanese Patent Application Publication No. 2019-209941 Summary of the Invention [Problem to be solved by the invention]
[0010] In the prior art described in the publication, as mentioned above, when attaching the partition weatherstrip 30 to the mirror bracket 32, the two insertion portions 31b are inserted vertically into the corresponding two insertion holes 33b.
[0011] However, depending on the accuracy of the extrusion molding of the partition weatherstrip 30 or the processing accuracy of the press molding of the mirror bracket 32, there is a risk that variations will occur in the formation position of each insertion portion 31b and each insertion hole 33b, or that variations will occur in the outer shape of each insertion portion 31b and the inner shape and size of each insertion hole 33b.
[0012] This makes it difficult to insert the insertion portions 31b into the insertion holes 33b, or in some cases, makes insertion impossible, making it difficult to attach the partition weather strip 30 to the mirror bracket 32.
[0013] In particular, since there are two insertion portions 31b and two insertion holes 33b, high accuracy in alignment, such as the distance between these, is required, and the aforementioned molding errors and processing errors can easily make insertion even more difficult, which could make the installation work of the partition weather strip 30 even more difficult.
[0014] The present invention was devised in consideration of the above-mentioned conventional technical problems, and aims to provide a partition weatherstrip mounting structure that can improve the efficiency of positioning and mounting the partition weatherstrip relative to the mirror bracket. [Means for solving the problem]
[0015] The invention described in claim 1 of the present application is a mounting structure for a partition weatherstrip, which is mounted between a door panel at the front end of a vehicle's front door and a door sash and a center sash, and which holds the outer periphery of a partition glass. The bottom edge of the partition weatherstrip is attached to a bracket fixed to the door panel by sliding the bottom edge of the partition weatherstrip onto an upper surface of the bottom wall of the bracket, A locking hole for positioning is provided at a predetermined position in the longitudinal direction on the top surface of the bottom wall of the bracket, A protrusion is provided on the underside of the bottom edge of the partition weather strip, and the protrusion is inserted into the locking hole when the bottom edge is slid. a lower surface of the protrusion is formed in a downward slope from a front end edge of the protrusion on the vehicle front side to a rear end edge of the protrusion on the vehicle rear side, The inclined lower surface is characterized in that it can come into sliding contact with the upper surface of the bottom wall of the bracket when the base portion is slid. [Effects of the Invention]
[0016] According to the present invention, the efficiency of the positioning and installation work of the partition weather strip relative to the bracket can be improved. [Brief explanation of the drawings]

[0018] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a partition weatherstrip mounting structure according to the present invention will now be described in detail with reference to the accompanying drawings.
[0019] Fig. 2 is an enlarged view of part A in Fig. 1, with some parts shown in perspective. Fig. 3 is an exploded perspective view of the partition weather strip and mirror bracket used in this embodiment. Fig. 4 is a cross-sectional view taken along line BB in Fig. 2, and Fig. 5 is a cross-sectional view taken along line CC in Fig. 2.
[0020] As shown in Figure 1, a door sash 3 is provided on the top of a door body 2 of a front door 1 of an automobile vehicle, and this door sash 3 is formed by joining an end portion of an inner panel 2a on the inside of the vehicle with an end portion of an outer panel 2b on the outside of the vehicle by hemming. At the front end of the window portion of the front door 1, a partition weatherstrip 5 is arranged in a closed loop around the door body 2, door sash 3, and center sash 4.
[0021] As shown in Fig. 2, the partition weatherstrip 5 is formed into a substantially rectangular shape in side view by extrusion molding of a resin or rubber material such as polyvinyl chloride, vinyl chloride (PVC), or polypropylene (PP). That is, as shown in Figs. 2 and 3, the partition weatherstrip 5 has a bottom side portion 6 placed on and held on the upper surface of a bottom wall 18b of a mirror bracket 18 (described later) fixed to the inner panel 2a of the door body 2, an inclined side portion 7 rising obliquely from the front end of the bottom side portion 6 toward the rear of the vehicle and fitted and held at the front end of the door sash 3, and a vertical side portion 8 rising almost vertically from the rear end of the bottom side portion 6, the upper end of which is connected to one end of the inclined side portion 7 and fitted and held at the center sash 4, and these components form a substantially rectangular shape as a whole.
[0022] 4 and 5, the partition weatherstrip 5 is formed with a substantially U-shaped cross section, and its inner periphery is provided with a glass holding portion 10 that fits over and holds the peripheral edge of the triangular partition glass 9. The bottom portion 6 of the partition weatherstrip 5 has a lower wall 11 and an interior side wall 12 and an exterior side wall 13 that rise from both interior and exterior side edges of the lower wall 11, and a portion of the glass holding portion 10 is formed between the lower wall 11 and the interior and exterior side walls 12, 13.
[0023] The interior side wall 12 has two upper and lower retaining lips 12a and 12b protruding toward the interior of the vehicle on its outer surface on the interior side of the vehicle, and these retaining lips 12a and 12b are designed to hold the end of the door trim 14 that extends to the upper end of the inner panel 2a.
[0024] The outer side wall 13 has a support lip 13a projecting from the vehicle interior side and abutting against the upper end of a molding 16 attached to the upper end of a mirror bracket 18 on the outer surface of the vehicle exterior.
[0025] The lower wall 11 has three elastic lips 11a, 11b, 11c protruding downward from the inside and outside ends of the bottom surface of the vehicle, which elastically contact the upper surface of the bottom wall 18b of the mirror bracket 18, and one protrusion 17 is provided at a predetermined position in the longitudinal direction of the bottom surface.
[0026] FIG. 6 is a perspective view showing a part of the partition weatherstrip used in this embodiment from below, and FIG. 7 is a side view of the main part showing the protrusions provided on the partition weatherstrip used in this embodiment.
[0027] 6 and 7, the protrusion 17 is formed in the shape of a rectangular block along the longitudinal direction of the base 6, and is formed in a rectangular shape when viewed from the side of its underside 17a. The underside 17a of the protrusion 17 is formed so as to slope downward from a front edge 17b at the front of the vehicle to a rear end surface 17c at the rear of the vehicle, and is formed in a substantially right-angled triangle when viewed from the side. In other words, the underside 17a of the protrusion 17 is formed so as to slope gradually downward from the front edge 17b to the edge of the rear end surface 17c, and the rear end surface 17c is formed as a rectangular surface hanging down from the lower end surface 11d of the lower wall 11 of the base 6.
[0028] The inclination angle of the lower surface 17a is set so that when the partition weatherstrip 5 is held and attached to the door sash 3 or mirror bracket 18 from the rear of the vehicle, the lower surface 17a is approximately parallel to the upper surface of the bottom wall 18b of the mirror bracket 18 when the partition weatherstrip 5 is tilted so that the front end of the bottom portion 6 of the partition weatherstrip 5 is lower (see Figure 9(b)).
[0029] The bottom edge 6 of the partition weatherstrip 5 is attached to a mirror bracket 18 provided below the belt line BL (see FIG. 1) of the door body 2 for attaching a door mirror. The mirror bracket 18 is disposed between the inner panel 2a and outer panel 2b of the door body 2 for attaching a door mirror (not shown).
[0030] 3, the mirror bracket 18 is formed by pressing an elongated metal plate, for example, and is arranged along the longitudinal direction of the vehicle body, with its front end 18a bent into a substantially L-shape along the front end of the door body 2 and the door sash 3, and welded and fixed to the door sash 3. The mirror bracket 18 also has a substantially L-shaped cross section, so that it holds the bottom edge 6 of the partition weatherstrip 5 between itself and the terminal portion of the inner panel 2a. The mirror bracket 18 has a flat bottom wall 18b on which the partition weatherstrip 5 rests, and an outer wall 18c that rises from one side edge of the bottom wall 18b.
[0031] FIG. 8 is a plan view of the main part showing the locking holes provided in the mirror bracket used in this embodiment.
[0032] As shown in FIG. 8 , a locking hole 20 is formed in the bottom wall 18b of the mirror bracket 18 at a predetermined longitudinal position, penetrating the bottom wall 18b in the vertical direction. The locking hole 20 is elongated along the longitudinal direction of the bottom wall 18b, approximately at the center of the width of the bottom wall 18b. The locking hole 20 is formed in a substantially rectangular shape with a uniform width W between both side edges, and the front and rear end edges 20a, 20b are formed in a substantially arc-like shape. The longitudinal length L is slightly longer than the longitudinal length L1 of the protrusion 17, allowing the protrusion 17 to be inserted therein. The locking hole 20 is designed to position the partition weatherstrip 5, allowing the protrusion 17 to be inserted therein, when the partition weatherstrip 5 is attached to the mirror bracket 18.
[0033] [Functions and Effects of the Partition Weatherstrip Mounting Structure According to the Present Embodiment] Figure 9(a) is a side view showing the state before the partition weatherstrip 5 is attached to the door sash 3 or the mirror bracket 18, Figure 9(b) is a side view showing the state in the middle of being attached by sliding the partition weatherstrip 5 onto the upper surface of the bottom wall 18b of the mirror bracket 18, Figure 9(c) is an enlarged side view of the main part showing the state just before the protrusion 17 of the partition weatherstrip 5 falls into and engages with the locking hole of the mirror bracket 18, and Figure 9(d) is a side view showing the state when the protrusion 17 falls into and engages with the locking hole 20 and the bottom part of the partition weatherstrip 5 is attached to the mirror bracket 18.
[0034] The procedure for attaching the partition weather strip 5 to the door sash 3, mirror bracket 18, etc. will be described below with reference to FIGS. 9(a) to 9(d).
[0035] First, as shown in Figure 9(a), on the front door 1 side, the center sash 4 is removed in advance, and the partition glass 9 is already fitted and held in the glass holding portion 10 of the partition weatherstrip 5.
[0036] In this state, the worker holds the partition weatherstrip 5 together with the partition glass 9 and pushes it in the direction of the black arrow in the figure, that is, from the rear of the vehicle toward the front door sash 3, moving the bottom edge 6 of the partition weatherstrip 5 forward while making sliding contact with the upper surface of the bottom wall 18b of the mirror bracket 18. In this state, the front side of the partition weatherstrip 5 is tilted downward at a predetermined angle, so the lower surface 17a of the protrusion 17 of the partition weatherstrip 5 slides forward while making sliding contact with the upper surface of the bottom wall 18b.
[0037] 9(c) and 9(d), when the protrusion 17 reaches the locking hole 20 of the mirror bracket 18 at a predetermined sliding position, it drops into and engages with the locking hole 20. This restricts further forward and rearward movement of the partition weatherstrip 5, and the partition weatherstrip 5 is positioned in the front-to-rear and left-to-right width directions relative to the bottom wall 18b at this position.
[0038] Thereafter, the center sash 4 is attached to the vertical side portion 8 of the partition weatherstrip 5, and the installation work of the partition weatherstrip 5 is completed.
[0039] As described above, in this embodiment, the lower surface 17a on the underside of one of the protrusions 17 of the partition weatherstrip 5 is simply slid onto the upper surface of the bottom wall 18b of the mirror bracket 18 and engaged with one of the engagement holes 20 of the mirror bracket 18. Therefore, even if molding errors occur during the extrusion molding of the partition weatherstrip 5 or processing errors occur during the molding process of the mirror bracket 18, the positioning and attachment work of the partition weatherstrip 5 to the mirror bracket 18 can be carried out easily and reliably.
[0040] In particular, because the partition weatherstrip 5 is slid while the inclined lower surface 17a of the protrusion 17 is in sliding contact with the upper surface of the bottom wall 18b of the mirror bracket 18, the amount of change in the height of the partition weatherstrip 5 caused by the protrusion 17 during this sliding movement is small. In other words, the partition weatherstrip 5 changes little in height in the up-down direction during sliding movement. As a result, the inclined side portion 7 and the upper ends of the vertical side portion 8 of the partition weatherstrip 5 do not interfere with the door sash 3 during sliding movement, preventing a deterioration in mobility.
[0041] Furthermore, according to this embodiment, the locking hole 20 is formed in the shape of an elongated hole, so that the rectangular block-shaped protrusion 17 slides against the longitudinal rear end edge 20b of the locking hole 20 via the inclined lower surface 17a, and the entire protrusion 17 falls into and engages with the locking hole 20, providing a sense of click when positioning is complete. Second Embodiment Figure 10 shows a second embodiment of the present invention, in which the basic structure of the partition weatherstrip 5 and mirror bracket 18 is the same as that of the first embodiment, but the difference is that the shape of the protrusion 17 of the partition weatherstrip 5 has been changed.
[0042] That is, the protrusion 17 is formed in a substantially obtuse triangle shape when viewed from the side, with the inclined lower surface 17a and rear end surface 17c joined at an obtuse angle, and the rear end surface 17c is also formed in a slightly inclined shape.
[0043] Therefore, in this second embodiment, as in the first embodiment, when the partition weatherstrip 5 is attached, the inclined lower surface 17a of the protrusion 17 smoothly slides over the upper surface of the bottom wall 18b of the mirror bracket 18 with little vertical variation, thereby achieving the same operational effects as the first embodiment.
[0044] The other configurations are the same as those of the first embodiment, and therefore the same effects can be obtained. Third Embodiment FIG. 11 shows a third embodiment of the present invention, in which the shape of the protrusions 17 of the partition weather strip 5 is further modified as in the second embodiment.
[0045] That is, the protrusion 17 is formed in a substantially arc shape in a side view, and the joining portion (top) of the inclined lower surface 17a and the rear end surface 17c is joined by a gently sloping arc surface 17d.
[0046] Therefore, according to this third embodiment, since the protrusion 17 has an arcuate surface 17d at the top, when the partition weatherstrip 5 is installed, the inclined lower surface 17a of the protrusion 17 slides against the upper surface of the bottom wall 18b of the mirror bracket 18, and at this time, the arcuate surface 17d ensures smooth sliding movement.
[0047] The other configurations are the same as those of the first and second embodiments, and therefore the same effects as those of the first and second embodiments can be obtained. [Fourth embodiment] FIG. 12 shows a fourth embodiment of the present invention, in which the shape of the locking hole 20 of the mirror bracket 18 is modified.
[0048] That is, the locking hole 20, which is formed as an elongated hole as in the first embodiment, has two opposing hole edges at approximately the center in the longitudinal direction that protrude inward in an arc shape, forming a roughly gourd-like shape in plan view. The width W1 between the opposing edges of the two inwardly protruding protrusions 20c, 20d is formed slightly larger than the width of the protrusion 17 of the partition weatherstrip 5, so that both side surfaces of the protrusion 17 can abut against the opposing inner edges of the protrusions 20c, 20d when engaged.
[0049] Therefore, according to this embodiment, by making both protrusions 20c, 20d of the locking hole 20 protrude inward to form narrowed portions, the sense of click when the protrusion 17 drops and engages can be further increased.
[0050] The present invention is not limited to the configuration of each embodiment, and the shape of the protrusion 17 can be formed, for example, in a square shape when viewed from the bottom, or can be made the same shape as the shape of the engagement hole 20. [Explanation of symbols]
