Description

[Technical Field]

[0001] The present invention relates to a structure for attaching a glass run to a sash door of a vehicle. [Background technology]

[0002] Patent Document 1 below discloses a sash door for a vehicle. The sash door disclosed in Patent Document 1 is a front door, and a triangular window is installed in front of the front door. The rear edge of the glass of the triangular window is held by a split sash, and the door glass behind the split sash can be raised and lowered to open and close. In order to guide the raising and lowering of the door glass and to hold the periphery of the closed door glass, a curved glass run is attached from the rear edge of the split sash to the lower edge of the door sash. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2021-11199 Summary of the Invention [Problem to be solved by the invention]

[0004] Glass runs are easily displaced because they are dragged by the sliding resistance of the door glass when the door glass is raised or lowered. Improving the airtightness, liquid tightness, and sound insulation of a closed door glass tends to increase the sliding resistance. For this reason, glass runs must be attached to the sash in a way that prevents them from dislocating. The glass run mounting structure disclosed in Patent Document 1 has a protrusion on the glass run along the lower edge of the door sash, which is engaged with an engagement hole formed in the door sash. Because the engagement hole is formed in the door sash, there is a risk that water, such as rainwater or car wash water, may enter the vehicle interior through the engagement hole.

[0005] An object of the present invention is to provide a door glass run mounting structure that can securely mount a glass run to a sash while preventing water from entering. [Means for solving the problem]

[0006] The present invention is a mounting structure for a glass run for a retractable glass in a sash door having a retractable glass adjacent to a fixed glass. The glass run is attached continuously from a split sash provided between the fixed glass and the retractable glass to the door sash. The end of the split sash is fixed to the door sash by a bracket. An engaging protrusion projects from the glass run toward the door sash. The engaging portion that engages with the engaging protrusion is formed on the bracket, not on the door sash. [Effects of the Invention]

[0007] According to the door glass run mounting structure of the present invention, the glass run can be securely mounted to the sash while preventing water from entering. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0009] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A door glass run mounting structure according to an embodiment will be described with reference to the drawings.

[0010] 1 to 6 show a door glass run mounting structure according to a first embodiment. FIG. 1 shows an enlarged side view of a portion of a vehicle front door 1 as seen from outside the vehicle. The front door 1 is a sash door. Note that FIG. 1 does not show door mirrors. A fixed glass 2 is provided in the front portion of the front door 1. Adjacent to and behind the fixed glass 2, a retractable glass 3 that can be opened and closed by raising and lowering is also provided. However, FIG. 1 only shows the position of the retractable glass 3. The front door 1 has a door sash 4 that holds the fixed glass 2 and the periphery of the retractable glass 3 when closed.

[0011] As will be explained in more detail later, the door sash 4 is mainly composed of an outer panel 4a and an inner panel 4b (see Figure 6), with the outer panel 4a being visible in Figure 1. A split sash 5 is provided between the fixed glass 2 and the retractable glass 3. A connection 6 between the door sash 4 and the split sash 5 is bent. A glass run 7 is attached continuously from the split sash 5 to the connection 6 and to the door sash 4. The glass run 7 guides the retractable glass 3 as it rises and falls, and also holds the periphery of the closed retractable glass 3. Airtightness and liquid tightness are ensured between the closed retractable glass 3 and the glass run 7. The glass run 7 also functions to reduce noise from outside the vehicle.

[0012] Glass run 7 has a first bent portion 7a that matches the bent shape of connection portion 6 between split sash 5 and door sash 4. In order to guide the raising and lowering of retractable glass 3, glass run 7 has a vertical portion that extends almost vertically below first bent portion 7a and extends into the interior of front door 1. As shown in FIG. 1 , glass run 7 is attached from the rear edge of split sash 5 to the lower edge of door sash 4.

[0013] As described above, the glass run 7 ensures airtightness and liquidtightness, and therefore, if the mounting position of the glass run 7 is misaligned, the airtightness and liquidtightness may become insufficient. Furthermore, when the lift-up glass 3 is raised or lowered, the glass run 7 is dragged by the sliding resistance with the lift-up glass 3, which makes it prone to misalignment. In particular, the glass run 7 is prone to being dragged upward when the lift-up glass 3 is raised, and if the bending connection portion 6 and the first bending portion 7a become misaligned, the airtightness and liquidtightness may become insufficient. The mounting structure of this embodiment prevents such misalignment.

[0014] The mounting structure that prevents the above-mentioned misalignment will be described in detail with reference to Figures 2 to 6. This mounting structure is characterized by the above-mentioned connection portion 6. Note that Figures 2 and 3 do not show the outer panel 4a (see Figure 6) of the door sash 4, but only the inner panel 4b. In Figure 2, the inner panel 4b is indicated by a two-dot chain line. In Figure 4, the door sash 4 is not shown, and in Figure 5, only the glass run 7 is shown.

[0015] A bracket 8 for attachment to the door sash 4 is fixed to the upper end of the split sash 5. The bracket 8 also has a second bent portion 8a that matches the bent shape of the connecting portion 6. The base end of the bracket 8 is spot welded to the split sash 5, and the top of the bracket 8 is fastened to the door sash 4 with a screw 9. The inner panel 4b is formed with an access hole 4d for the screw 9 and an attachment hole 4e for attaching the weatherstrip of the inset glass 2.

[0016] The door sash 4 of this embodiment has a reinforcing plate 4c fixed to the back surface of the inner panel 4b by spot welding. A bracket 8 is fastened to this reinforcing plate 4c with screws 9. The reinforcing plate 4c has insertion holes through which the screws 9 are inserted, and the screws 9 inserted into these insertion holes are threaded into screw holes 8b in the bracket 8. The periphery of the insertion holes and the screw holes 8b in the reinforcing plate 4c is recessed to accommodate the heads of the screws 9, so that the top surfaces of the heads of the screws 9 and the top surface of the inner panel 4b are substantially flush with each other. The reinforcing plate 4c has mounting holes 4f formed in it that align with the mounting holes 4f in the inner panel 4b, for mounting a weatherstrip for the installed glass 2. Positioning protrusions formed on the weatherstrip are inserted into these mounting holes 4e and 4f to ensure liquid-tightness.

[0017] The bracket 8 also has an engagement through-hole 80 formed therein as an engagement portion 8c that engages with an engagement protrusion 7b of the glass run 7, which will be described later. The engagement through-hole 80 is formed in the middle of the tip portion, above the second bent portion 8a. The bracket 8 also has an engagement piece 8d formed at the very tip of the tip portion of the bracket 8, which protrudes toward the door sash 4. The bracket 8 also has the above-mentioned screw hole 8b, into which the screw 9 is screwed, formed in the vicinity of the second bent portion 8a. That is, the screw hole 8b into which the screw 9 is screwed is formed between the engagement portion 8c (engagement through-hole 80) and the second bent portion 8a, and the engagement piece 8d is formed on the opposite side of the engagement portion 8c (engagement through-hole 80) from the screw hole 8b.

[0018] An engagement hole 4g ​​that engages with the engagement piece 8d of the bracket 8 is formed at the tip of the reinforcing plate 4c of the door sash 4. This engagement hole 4g ​​is covered by the inner panel 4b and cannot be seen from the outside. As described above, the split sash 5 is fastened to the reinforcing plate 4c via the bracket 8 with the screw 9. When fastening, a rotational force that rotates the bracket 8 is generated due to sliding resistance with the rotating screw 9. The engagement piece 8d and the engagement hole 4g ​​are formed to fasten the bracket 8 in the correct position.

[0019] When the bracket 8 is fastened with the screw 9, a rotational force is generated that rotates the bracket 8 clockwise in Fig. 2. At this time, as shown in Fig. 2, the engagement piece 8d abuts against the inner peripheral edge of the engagement hole 4g, so the bracket 8 is held in a correct fixed position relative to the door sash 4. In addition, the engagement piece 8d is located at the farthest position from the screw hole 8b, and the abutment between the engagement piece 8d and the engagement hole 4g ​​can effectively resist the torque around the screw hole 8b that attempts to rotate the bracket 8.

[0020] The glass run 7 is a rubber member that is attached continuously from the split sash 5 fixed to the door sash 4 to the door sash 4 to ensure airtightness and liquidtightness. To prevent the glass run 7 from shifting in its attachment position relative to the split sash 5 and the door sash 4, an engagement protrusion 7b that engages with the above-mentioned engagement through-hole 80 (engagement portion 8c) of the bracket 8 protrudes from the vicinity of the first bent portion 7a of the glass run 7 toward the door sash 4. The engagement between the engagement protrusion 7b and the engagement through-hole 80 (engagement portion 8c) also prevents the glass run from shifting in position when the retractable glass 3 moves up and down.

[0021] To ensure reliable engagement between the engaging projection 7b and the engaging through-hole 80 (engagement portion 8c), the inner surface of the door sash 4 (inner panel 4b) is spaced apart from the portion of the bracket 8 where the engaging through-hole 80 is formed, forming a gap 10 (see FIGS. 3 and 6). By separating the inner surface of the inner panel 4b from the bracket 8 to form the gap 10, the engaging projection 7b abuts against the inner peripheral edge of the engaging through-hole 80 not at its very tip but at a position closer to its base end. As a result, the engaging projection 7b is less likely to come out of the engaging through-hole 80, and displacement of the glass run 7 relative to the split sash 5 and the door sash 4 is reliably prevented.

[0022] Furthermore, the engagement structure of the engagement protrusion 7b and the engagement through-hole 80 is provided near the connection portion 6 between the door sash 4 and the split sash 5. That is, the engagement protrusion 7b is provided near the first bent portion 7a of the glass run 7, and the engagement through-hole 80 is provided near the second bent portion 8a of the bracket 8. As described above, when the retractable glass 3 rises, the glass run 7 is dragged upward by the sliding resistance between its vertical portion along the split sash 5 and the retractable glass 3. This drag force acts on the first bent portion 7a, but by providing the above-mentioned engagement structure near the first bent portion 7a, it is possible to effectively prevent misalignment of both the vertical portion of the glass run 7 along the split sash 5 and the diagonal portion of the glass run 7 along the door sash 4.

[0023] When attaching the glass run 7 to the door sash 4 and the split sash 5, which are fixed to each other, the worker cannot attach the glass run 7 while directly visually checking the engaging protrusion 7b and the engaging through-hole 80. However, if the worker attaches the glass run 7 by matching the bending shape of the first bent portion 7a with the bending shape of the second bent portion 8a at the connecting portion 6 described above, the worker can more easily engage the engaging protrusion 7b with the engaging through-hole 80.

[0024] With reference to FIG. 6, the state in which the retractable glass 3 is closed will be briefly described. As shown in FIG. 6, the glass run 7 is attached to the door sash 4 (outer panel 4a and inner panel 4b). At this time, the inner surface of the door sash 4 (reinforcing plate 4c) is spaced from the bracket 8 to form a gap 10. Therefore, the engaging protrusion 7b protrudes into the gap 10 through the engaging through-hole 80 and firmly engages with the engaging through-hole 80. The engaging portion 8c (engaging through-hole 80) that engages with the engaging protrusion 7b is formed in the bracket 8, so there is no need to provide an engaging hole in the door sash 4 (inner panel 4b) to engage with the engaging protrusion 7b. Therefore, there is no need to form a hole in the door sash 4 (inner panel 4b) for an engaging structure to prevent misalignment of the glass run 7, and this engaging structure prevents water from entering from the top surface of the door sash 4 (inner panel 4b).

[0025] A U-shaped outer lip 7c is formed at the lower edge of the glass run 7 on the outer side of the vehicle. The outer edge of the outer lip 7c is in close contact with the outer panel 4a, ensuring airtightness and liquid-tightness. The inner edge of the outer lip 7c is in close contact with the closed lift-up glass 3, ensuring airtightness and liquid-tightness. Similarly, a U-shaped inner lip 7d is formed at the lower edge of the glass run 7 on the inner side of the vehicle. The inner edge of the inner lip 7d is in close contact with the inner panel 4b, ensuring airtightness and liquid-tightness. The outer edge of the inner lip 7d is in close contact with the closed lift-up glass 3, ensuring airtightness and liquid-tightness.

[0026] Next, a door glass run mounting structure according to a second embodiment will be described with reference to Fig. 7. Fig. 7 is a view corresponding to Fig. 4 of the first embodiment. Although the door sash 4 is not shown in Fig. 7, the fixing of the split sash 5 to the door sash 4, i.e., the screwing of the bracket 8 to the door sash 4, is the same as in the first embodiment. In this embodiment, only the shape of the engaging portion 8c of the bracket 8 differs from the first embodiment. While the engaging portion 8c in the first embodiment was formed as an engaging through-hole 80 penetrating the bracket 8, the engaging portion 8c in this embodiment is formed as an engaging notch 81 penetrating the bracket 8.

[0027] In other words, the engagement notch 81 of this embodiment can be said to be the engagement through-hole 80 of the first embodiment opened to the side. As described above, when installing the glass run 7, the worker cannot directly visually check the engagement protrusion 7b and engagement notch 81 of the glass run 7. The glass run 7 is installed by installing the vertical portion below the first bent portion 7a that extends along the divided sash 5 to the inside of the front door 1, and by installing the oblique portion above the first bent portion 7a that extends along the door sash 4. At this time, the engagement protrusion 7b is brought close to the bracket 8 from above in FIG. 7 and engaged with the engagement notch 81.

[0028] Because the engagement notch 81 in this embodiment is open on the sides, even if the engagement protrusion 7b moves to the side when approaching the bracket 8, the engagement protrusion 7b can enter the engagement notch 81 from the side, improving workability. Furthermore, the engagement piece 8d of the bracket 8 described above is formed by bending the tip of the plate-shaped bracket 8 toward the door sash 4. Therefore, a curved portion is formed at the base of the engagement piece 8d, and this curved portion and the surface of the reinforcing plate 4c guide the movement of the engagement protrusion 7b toward the engagement notch 81, preventing the engagement protrusion 7b from getting caught when the glass run 7 is attached. This is the same as in the first embodiment.

[0029] In this embodiment as well, the portion where the engaging projection 7b and the engaging notch 81 engage is spaced from the inner surface of the door sash 4 (inner panel 4b), forming a gap 10 (however, reference numeral 10 is not shown in FIG. 7). Therefore, the engaging projection 7b and the engaging notch 81 are again securely engaged with each other, and displacement of the glass run 7 relative to the divided sash 5 and the door sash 4 is reliably prevented.

[0030] According to the above embodiment, in the mounting structure for the glass run 7 for the retractable glass 3, the glass run 7 is mounted continuously from the split sash 5 to the door sash 4. An end of the split sash 5 is fixed to the door sash 4 by a bracket 8. An engaging protrusion 7b protrudes from the glass run 7 toward the door sash 4. An engaging portion 8c (engaging through-hole 80 or engaging notch 81) that engages with the engaging protrusion 7b is formed in the bracket 8, not in the door sash 4. Therefore, there is no need to form a hole in the door sash 4 for the engaging structure that prevents the glass run 7 from shifting in position, and this engaging structure prevents water from entering from the top surface of the door sash 4. Furthermore, this engaging structure prevents the glass run 7 from shifting in position, allowing the glass run 7 to be reliably mounted to the door sash 4 and the split sash 5.

[0031] Furthermore, according to the above embodiment, the glass run 7 has a first bent portion 7a that aligns with the bent connecting portion 6 between the split sash 5 and the door sash 4, and the bracket 8 has a second bent portion 8a that aligns with the connecting portion 6. The engaging protrusion 7b is formed near the first bent portion 7a, and the engaging through-hole 80 or the engaging notch 81 is formed near the second bent portion 8a. Therefore, an engaging structure that prevents displacement of the glass run 7 is provided near the connecting portion 6 (first bent portion 7a, second bent portion 8a), and displacement of the glass run 7 can be more effectively prevented. Furthermore, according to the above embodiment, the inner surface of the door sash 4 and the portion of the bracket 8 where the engaging through-hole 80 or the engaging notch 81 is formed are spaced apart. Therefore, the engaging protrusion 7b and the engaging through-hole 80 or the engaging notch 81 reliably engage with each other, and displacement of the glass run 7 can be more effectively prevented.

[0032] Furthermore, according to the above embodiment, the door sash 4 has a reinforcing plate 4c between it and the bracket 8, and the bracket 8 is fixed to the door sash 4 by fastening it to the reinforcing plate 4c with the screw 9. The bracket 8 has a screw hole 8b formed between the engaging portion 8c and the second bent portion 8a, into which the screw 9 is threaded, and an engaging piece 8d formed on the engaging portion 8c on the opposite side of the screw hole 8b toward the door sash 4. The reinforcing plate 4c has an engaging hole 4g ​​formed therein that engages with the engaging piece 8d. Therefore, engagement between the engaging piece 8d and the engaging hole 4g ​​prevents misalignment of the bracket 8 due to rotation when the screw 9 is threaded, thereby fixing the bracket 8 in the correct position. By ensuring as long a distance as possible between the screw hole 8b and the engaging piece 8d, torque that tends to rotate the bracket 8 when the screw 9 is threaded can be effectively resisted. Furthermore, because this engagement structure does not require the formation of a hole in the door sash 4, this engagement structure also prevents water from entering from the top surface of the door sash 4.

[0033] The door glass run mounting structure of the present invention is not limited to the above embodiment. The mounting structure of the above embodiment is installed on a front door with a fixed glass in the front. However, there are also rear doors with fixed glass in the rear, and the mounting structure of the present invention can be applied to such rear doors. [Explanation of symbols]
