Description

  The present invention relates to a stopper structure for a glass run provided on a vehicle door in a state where a part thereof is attached to a division bar.

  Generally, the periphery of a window panel (door glass) in a vehicle such as an automobile is held by a glass run. The glass run includes a front side portion and a rear side portion that extend in the vertical direction corresponding to the window frame shape of the door, and an upper portion that extends continuously in the front-rear direction between the upper ends of the front side portion and the rear side portion. . The glass run is provided on the door of the vehicle with the rear side part attached to the division bar. In the glass run, the front side portion and the rear side portion guide the raising and lowering of the window panel.

  Conventionally, there has been proposed a weather strip integrated with a glass run that guides a side portion of a window panel through a slider when the window panel moves up and down (see, for example, Patent Document 1). In Patent Document 1, when the upper end surface of the window panel comes into contact with the weather strip, a stopper member embedded in the weather strip regulates the rising of the window panel via the weather strip.

In addition, a glass run in which a protrusion protruding outward is formed in a rear corner portion, and a division bar in which a notch capable of locking the protrusion is formed (for example, see Patent Document 2). ). In Patent Document 2, the glass run and the division bar are temporarily assembled by locking the protrusions in the notches, and then both are assembled to the rear door, thereby preventing the glass run from coming off the division bar during assembly. is doing.

  Generally, the upper end of the window panel of the rear door is formed in a curved shape that descends toward the rear side. In addition, since the window panel is moved up and down using the rotational motion of the window regulator, when the upper end surface of the window panel comes into contact with the upper portion of the glass run, friction occurs between the glass run and the window panel. The glass run is pulled not only in the upward direction but also in front of the vehicle. For this reason, the glass run at the corner portion shifts over time, and the appearance is deteriorated.

  Patent Document 1 discloses a configuration in which a stopper member embedded in a weather strip regulates the rising of the window panel via the weather strip. However, there is no disclosure that suggests a configuration that suppresses the occurrence of displacement due to the glass run being pulled from the window panel in front of the vehicle.

  In Patent Document 2, the protrusion and the notch are locked to prevent the glass run from coming off the division bar when the glass run is assembled to the rear door. However, Patent Document 2 does not consider any inconvenience due to a situation in which the glass run is pulled when the upper end surface of the window panel comes into contact with the glass run. Therefore, also in patent document 2, the shift | offset | difference of the glass run over time cannot be prevented, and the external appearance of a vehicle door is impaired.

  The present invention has been made in view of the above-described problems, and its object is to suppress a glass run that is pulled forward of the vehicle and shift it, and to maintain a good appearance of the vehicle door. To provide a structure.

To achieve the above object, a first aspect of the present invention, part of a stopper structure of the glass run provided in a vehicle door in a state of being attached to the division bar, the glass run, the vehicle And a bracket for attaching the upper end portion of the division bar to the vehicle door engages with a protrusion provided on the upper surface of the upper portion to move the glass run forward. And a window panel ascending restricting part for restricting the raising of the window panel that is moved up and down via the upper part, and the engaging part is provided on the upper surface of the upper part a surface facing the front surface of the protruding portion as well as positioned in front of the projection, said window panel elevation regulating portion is a plane extending from the engaging portion forward along the upper surface of the upper portion And effect.

  According to this configuration, even if the glass run is pulled forward of the vehicle, the engagement portion of the bracket is engaged with the projection of the glass run, and the glass run is prevented from shifting. Therefore, the possibility of the glass run being deformed is low even over time, and the appearance of the vehicle door can be maintained well.

In addition, the bracket that had only the function of attaching the division bar to the vehicle door has been added with a function to restrict the window panel from rising, so the stopper member that restricts the window panel from rising is omitted accordingly. Can do.

The invention according to claim 2 is a glass run stopper structure provided on a vehicle door in a state in which a part is attached to a division bar, the glass run having an upper portion extending in the front-rear direction of the vehicle. The division bar is integrally formed with an attachment portion for attaching an upper end of the division bar to the door panel, and the attachment portion engages with a protrusion provided on the upper surface of the upper side portion , so that the front portion of the glass run An engagement portion that restricts movement to the window panel, and a window panel rise restriction portion that restricts the rise of the window panel that is moved up and down via the upper portion, and the engagement portion is an upper surface of the upper portion. The window panel rising restricting portion extends forward along the upper surface of the upper portion from the engaging portion, and is located on the front side of the protruding portion provided on the front surface of the protruding portion. And summary that is.

  According to this configuration, even if the glass run is pulled forward of the vehicle, the engagement portion is engaged with the protrusion provided on the upper end surface of the glass run, and the glass run is prevented from shifting. Therefore, the possibility of the glass run being deformed is low even over time, and the appearance of the vehicle door can be maintained well.

Moreover, since the attachment part of the division bar attached to a door panel also has a function which controls the raise of a window panel, the stopper member which regulates a glass raise can be omitted that much.
According to a third aspect of the present invention, in the first or second aspect of the present invention, the glass run includes a front side portion and a rear side portion extending in a vertical direction, and the upper side portion includes the front side portion and the rear side portion. It is formed so as to continuously extend in the front-rear direction between the upper ends of the side portions.

  ADVANTAGE OF THE INVENTION According to this invention, it can suppress that a glass run is pulled ahead of a vehicle and slip | deviates, and can maintain the external appearance of a vehicle door favorably.

Hereinafter, an embodiment embodying the present invention will be described with reference to FIGS.
As shown in FIG. 1A, a rear door 1 as a vehicle door includes a door outer panel 10, a door inner panel 11, and a window panel 12 that moves up and down by a window regulator (not shown).

A joined bracket 4 is provided. A stopper member 5 is connected to the door inner panel 11 and attached to the rear door 1. The stopper member 5 is formed by bending a plate material, and a part thereof is in contact with the upper surface 3 a of the glass run 3.

  The division bar 2 has a substantially H-shaped cross section. As shown in FIG. 1B, the upper end portion 20 of the division bar 2 is attached to the door inner panel 11 by the bracket 4. An attachment portion (not shown) connected to the rear door 1 is provided at the center portion and the lower end portion of the division bar 2, and the division bar 2 is attached to the rear door 1 at three locations of the upper end portion 20, the central portion and the lower end portion. It is done.

  The glass run 3 includes a front side portion 30 and a rear side portion 31 that extend substantially linearly in the vertical direction of the vehicle. The front side portion 30 is located on the front side of the rear door 1, and the rear side portion 31 is attached to the division bar 2 and located on the rear side of the rear door 1. Moreover, the glass run 3 is provided with the upper part 32 which continues between the upper ends of the front side part 30 and the rear side part 31, and is a substantially U shape. The upper part 32 extends in the front-rear direction of the vehicle while being inclined. As shown in FIG. 4, a groove 3b is formed in the glass run 3, and a lip 3c is provided to secure a seal between the window panel 12 and the glass run 3 which are guided by the groove 3b and move up and down. It is integrally formed.

  As shown in FIG. 1 (b), a protrusion 33 is provided on the upper surface 3 a of the glass run 3. The protrusion 33 is disposed so as to correspond to the rear end of the upper portion 32. The protrusion 33 is integrally formed with the glass run 3, and the glass run 3 and the protrusion 33 are made of a material such as soft rubber.

  As shown in FIG. 1 and FIG. 2, the bracket 4 formed by bending the plate material is attached to the door inner panel 11 and the joint portion 40 welded to the upper end portion 20 of the division bar 2. The connecting portion 41 extends from the joint portion 40 toward the vehicle front side and is inclined obliquely upward. Further, the bracket 4 includes an engaging portion 42 extending from the end of the connecting portion 41 toward the upper portion 32 of the glass run 3 positioned below the connecting portion 41, and the upper surface of the glass run 3 from the lower end of the engaging portion 42. And a contact portion 43 extending toward the vehicle front side along 3a.

  As shown in FIG. 3, the connecting portion 41 is provided with a screw hole 41 a into which a screw 6 as a connecting member attached to the door inner panel 11 is screwed. The bracket 4 is connected to the rear side of the door inner panel 11 by screwing the screw hole 41 a with the screw 6.

  The engaging portion 42 faces the front surface of the protrusion 33 in a state where the bracket 4 is connected to the door inner panel 11. Further, the lower end of the engaging portion 42 is positioned in front of the front boundary line 3 d that is the boundary between the protruding portion 33 and the upper surface 3 a, and the engaging portion 42 engages with the protruding portion 33.

  The contact portion 43 is plate-shaped and is in contact with the upper surface 3 a of the glass run 3 in a state of surface contact. The abutting portion 43 functions as a window panel rise restricting portion that restricts the window panel 12 from rising. A triangular pyramid-shaped rib 44 is formed between the engaging portion 42 and the contact portion 43, and the rib 44 corresponds to a bent portion of the bracket 4. By forming the rib 44, the rigidity of the contact portion 43 is enhanced.

Next, the operation of the bracket 4 configured as described above will be described.
The bracket 4 welded and joined to the upper end 20 of the division bar 2 is connected to the door inner panel 11 so that the upper end 20 of the division bar 2 is attached to the rear door 1. As shown in FIG. 4, in the rear door 1 to which the division bar 2 is attached, when the window panel 12 rises to the closed position, the upper end surface of the window panel 12 is the groove bottom surface 3e of the glass run 3. Abut. If the window regulator (not shown) for lifting the window panel 12, for example, as described in JP-A-200 0 -186 461 discloses, is to utilize a rotational movement of Udejo member having one end pivotally supported, the window panel A force is applied to 12 not only in the vertical direction but also in the rotation direction of the regulator, that is, in the front-back direction. Even when another type of lifting device for the window panel 12 is used, if the contact state is not uniform in the vehicle front-rear direction when the window panel 12 is in contact with the groove bottom surface 3e, it is still in the front-rear direction. Power is added to. For this reason, friction is generated between the window panel 12 and the groove bottom surface 3e of the glass run 3, and the upper portion 32 of the glass run 3 extending in the front-rear direction while inclining is obliquely forward (as schematically shown in FIG. 1B). Force is also applied to the figure.) Therefore, when the window panel 12 comes into contact with the groove bottom surface 3e of the glass run 3, the upper portion 32 is pulled forward. However, even if such a situation occurs, the engaging portion 42 locks the protrusion 33 and restricts the forward movement of the glass run 3.

  Here, in this embodiment, since the rear door 1 is configured as a press door, there is a distance between the upper surface 3a of the glass run 3 and the door inner panel 11, as shown in FIG. Therefore, when the upward force is applied from the window panel 12 to the glass run 3 without providing the stopper member 5 and the contact portion 43 for restricting the upward movement of the window panel 12, the glass run 3 is displaced. It may be deformed.

  Therefore, conventionally, the stopper members 5 for restricting the rising of the window panel 12 are respectively attached to the front side and the rear side of the door inner panel 11. The two stopper members 5 regulate the rising of the window panel 12 via the upper side portion 32 of the glass run 3. On the other hand, in this embodiment, the stopper member 5 attached to the rear side of the door inner panel 11 is omitted. As shown in FIG. 4, when the window panel 12 rises and contacts the groove bottom surface 3 e of the glass run 3, the contact portion 43 is the same as the stopper member 5 provided on the front side of the door inner panel 11. Further, the rising of the window panel 12 is restricted via the upper side portion 32. That is, the bracket 4 provided with the contact portion 43 as the window panel rise restricting portion also serves to restrict the rise of the window panel 12.

  In this embodiment, even if there is a distance between the upper surface 3a of the glass run 3 and the door inner panel 11, the glass run 3 is prevented from being displaced from the set position by the stopper member 5 and the contact portion 43, and the glass run is avoided. The deformation of 3 is suppressed.

This embodiment has the following effects.
(1) The bracket 4 includes an engaging portion 42, and the engaging portion 42 engages with the front end of the protrusion 33 provided on the upper surface 3 a of the glass run 3.

Therefore, since the glass run 3 is restrained from being pulled and displaced in the forward direction of the vehicle, the appearance of the rear door 1 can be favorably maintained without the glass run 3 being deformed.
(2) The bracket 4 includes an abutting portion 43 as a window panel ascent restricting portion that restricts the ascent of the window panel 12 via the upper side portion 32.

  Therefore, since a function for restricting the rise of the window panel 12 is added to the bracket 4, the stopper member 5 for restricting the rise of the window panel 12 can be omitted correspondingly.

(3) The rear door 1 is configured as a press door, and the contact portion 43 contacts the upper surface 3 a of the glass run 3.
Therefore, even if an upward force from the window panel 12 is applied to the glass run 3, it is avoided that the glass run 3 is displaced by the contact portion 43, and deformation of the glass run 3 is suppressed.

(4) The ribs 44 for increasing the rigidity of the contact portion 43 are formed.
When the contact portion 43 restricts the rise of the window panel 12, a force is applied to the contact portion 43 upward, but even if a force is applied, the contact portion 43 is deformed because the rib 44 is formed. It is difficult to do.

(5) The connecting portion 41 is provided with a screw hole 41a, and the screw hole 41a is screwed with a screw 6 attached to the door inner panel 11.
That is, the structure of the connecting portion 41 connected to the door inner panel 11 is the same as the conventional structure. Therefore, the bracket 4 of this embodiment can be attached to the rear door 1 by a conventional method without changing the configuration of the rear door 1.

The embodiment is not limited to the above, and may be embodied as follows, for example.
○ Instead of attaching the upper end 20 of the division bar 2 to the rear door 1 by the bracket 4 separate from the division bar 2, the upper end 20 of the division bar 2 is attached by the attachment 51 formed integrally with the division bar 2. You may attach to the door inner panel 11. FIG.

  In the case of such a configuration, for example, as shown in FIG. 5, the division bar 2 is formed in a substantially H-shaped cross section, and the attachment portion 50 to which the rear side portion 31 of the glass run 3 is attached. And an attachment portion 51 connected to the door inner panel 11.

  The attachment portion 51 extends from the attachment portion 50 and includes a connection portion 41, an engagement portion 42, and a contact portion 43. The connecting portion 41 is provided with a screw hole 41 a into which the screw 6 is screwed, and the mounting portion 51 is connected to the door inner panel 11 by screwing the screw 6 with the screw hole 41 a.

  In a state where the attachment portion 51 is connected to the door inner panel 11, the engaging portion 42 extending from the connecting portion 41 engages with the protrusion 33 provided on the upper surface 3 a. Further, the abutting portion 43 extending from the engaging portion 42 is disposed so as to abut on the upper surface 3 a of the glass run 3, and the mounting portion 51 including the abutting portion 43 serves to regulate the rise of the window panel 12. Also fulfills.

  Thus, instead of attaching the division bar 2 to the rear door 1 with the bracket 4, if the division bar 2 is directly attached to the door inner panel 11, the work of attaching the bracket 4 to the division bar 2 can be omitted. Therefore, the manufacturing process of the rear door 1 can be simplified.

  (Circle) the bracket 4 does not need to comprise by bending a board | plate material. For example, the bracket 4 may be made of a thick block material, and a recess for fitting the protrusion 33 into the bracket 4 made of the block material may be provided to engage the protrusion 33.

  The bracket 4 may not be attached to the door inner panel 11 by the screws 6 and the screw holes 41a attached to the door inner panel 11. For example, the bracket 4 may be attached to the door inner panel 11 by configuring the connecting portion 41 as a plate member not provided with the screw hole 41a and joining the connecting portion 41 to the door inner panel 11 by welding.

  A plurality of protrusions 33 may be provided on the upper surface 3 a of the glass run 3. For example, two protrusions 33 may be provided, and the engagement part 42 and the contact part 43 may be located between the two protrusions 33 provided.

  ○ The contact portion 43 may be omitted. In this case, the stopper member 5 is attached to the rear side of the door inner panel 11 instead of the contact portion 43, and the rising of the window panel 12 is restricted by the two stopper members 5.

In addition, the engaging portion 42 may be formed in a hook shape instead of a flat plate shape, and a recess may be provided on the front surface of the protrusion 33 so that the hook-like engaging portion 42 engages with the recess.
○ The shape of the division bar 2 is not particularly limited. For example, the shape of the division bar 2 may be an L-shaped section or a U-shaped section.

The location where the upper end 20 of the division bar 2 is attached may not be the door inner panel 11. For example, the upper end 20 may be attached to the door outer panel 10.
The shape of the rib 44 may not be a triangular pyramid shape. The shape of the rib 44 is not particularly limited.

○ The member used as the connecting member may not be the screw 6.
(Circle) You may comprise the glass run 3 and the protrusion 33 from a separate material, respectively. For example, soft rubber may be used as the material of the glass run 3, and hard resin may be used as the material of the protrusion 33.
