A glass run channel assembly for such an application is a groove-constituting member (elongated molding member) having a substantially U-shaped cross section formed in a long shape, and is mounted in a groove formed in a window frame, Guides the raising and lowering of a glass window plate that moves up and down in a component (for example, a door panel). The glass run channel assembly is generally manufactured by performing extrusion molding or the like using an elastic polymer material such as rubber or a thermoplastic elastomer.
This type of glass run channel assembly corresponds to the shape of the window frame, and includes a plurality of glass run channels formed into a long shape by extrusion molding and at least two long glass run channels. It is comprised from the connection glass run channel arrange | positioned in the corner part of a window frame as a molded object to connect. Such connection glass run channels are generally formed by injection molding.
In this type of glass run channel assembly, there is a possibility that the glass window plate is displaced from a predetermined mounting position due to a stress acting when the glass window plate is moved up and down, and it is necessary to devise a technique for preventing the positional displacement. As one means for preventing such positional deviation, it is known that a projection for preventing movement is integrally provided at a corner portion of the window frame (that is, the connection glass run channel). By causing the protrusions to contact a part of the window frame constituent member, it is possible to regulate the movement (position shift) of the glass run channel assembly accompanying the up-and-down movement of the window frame.

  For example, in Patent Document 1, an insert member made of a harder material than the mold forming portion is disposed in a portion (mold forming portion) corresponding to a corner portion of a glass opening portion in the glass run channel assembly, and the insert member described above A glass run channel assembly characterized in that the surface of a portion corresponding to a protrusion is covered with a material constituting the mold part (that is, a relatively soft material) and a method for manufacturing the glass run channel assembly are described.

In the above technique, the insert member constituting the protrusion is arranged in advance in the mold, and the insert member is integrated by injecting the molten material constituting the mold forming portion into the mold. It is necessary to mold the mold part. For this reason, it is necessary to fix the hard insert member in the mold to be used, and therefore the structure of the mold to be used is complicated. In addition, since the insert member is present in the cavity, the flow of the molten resin is hindered, or the heat of the molten resin is taken away, and there is a possibility of causing a short shot in which the molten resin does not sufficiently spread into the cavity.
(2). In addition, when the insert member is not correctly disposed at a predetermined regular position in the mold having the complicated structure due to the problem (1) or when the insert member itself is not inserted into the mold, Alternatively, when the insert member is displaced due to the pressure of the injected resin, a defective product that cannot be repaired may be formed. Further, when the mold is closed in a state where the insert member is not properly arranged at a predetermined regular position, there is a possibility that the mold is damaged.

Next, an engagement member 200 constituting the glass run product 100 according to the present embodiment and attached to (inserted into) the insertion hole will be described with reference to the drawings. FIG. 6 is a perspective view schematically showing the structure of the engaging member 200 according to the present embodiment.
The engaging member 200 according to the present embodiment is a member formed in advance separately from the connection glass run channel 150, and is a synthetic resin material that is harder and more rigid than the elastic polymer material forming the connection glass run channel 150, such as polyacetal. It is a molded product molded from an elastic polymer material such as (POM) or nylon (polyamide resin). The engaging member 200 may be a metal material press-molded product, cast product, forged product, or the like. Further, as shown in FIG. 6, the engaging member 200 includes a flat plate-like base portion 210 and a trunk portion 205 that protrudes (rises) in a direction away from the base portion 210.
The flat plate-like main body part 212 of the base part 210 is formed in a size and a shape that can be fitted into the base support part 168, and on the side facing the base part 175 when attached to the connection glass run channel 150. A plurality of misalignment prevention protrusions 214 are formed on the surface. On the other hand, the trunk 205 is formed so as to be inserted into the insertion hole 160 and attached to the connection glass run channel 150, and the protrusion 167 composed of the trunk 205 and the protrusion 165 inserted into the insertion hole 160 is a window frame. 22 (inclined frame 58) can be engaged with the engagement hole 40 formed.

The trunk portion 205 includes a columnar main body portion 207 of a size that can be inserted into the insertion hole 160 and a locking head portion 220 that protrudes from the tip of the columnar main body portion 207. When the engaging member 200 is attached to the connection glass run channel 150 on the base portion 210 side of the columnar main body portion 207, the end portion of the lateral inner wall 177 located on the inner peripheral side of the base portion 175 (that is, the lateral inner wall 177). A longitudinal-direction locking groove 224 that can be locked by the first longitudinal-direction locking portion 185 formed on the inner peripheral side end portion of the first longitudinal-direction locking portion 185 is formed. Further, the central side in the protruding direction (rising direction) of the wide surface of the columnar main body 207 (the surface parallel to the long side of the flat plate-shaped main body 212) is associated with the lateral inner wall 177 that forms the periphery of the insertion hole 160. A longitudinal locking ridge 230 is formed to stop.
Further, as shown in FIG. 6, the locking head 220 is set to be larger than the outer shape of the columnar main body 207, and the end of the lateral inner wall 177 positioned on the outer peripheral side of the base portion 175 (that is, the lateral inner wall). 177 formed on the outer peripheral side end portion of the longitudinal direction locking portion 188, and the end portion of the vertical inner wall 179 positioned on the outer peripheral side of the base portion 175. That is, a width-direction locking convex portion 222 that locks to the first width-direction locking portion 195 formed on the outer peripheral side end portion of the vertical inner wall 179 is provided.

Next, functions (actions and effects) of the connection glass run channel 150 to which the engagement member 200 is attached will be described in detail with reference to the drawings.
As shown in FIGS. 4 and 5, the engaging member 200 is attached to a predetermined position of the connection glass run channel 150 by inserting the trunk portion 205 into the insertion hole 160 and fitting the root portion 210 into the root support portion 168. It has been.
At this time, as shown in FIG. 4, in the connecting glass run channel 150, the first longitudinal locking portions 185 and 185 are engaged with the longitudinal locking grooves 224 and 224 of the engaging member 200 along the longitudinal direction. It has stopped. The longitudinal locking protrusions 230, 230 of the engaging member 200 are in contact with and locked to the lateral inner wall 177 of the inner walls that form the periphery of the insertion hole 160. Here, when the glass run product 100 including the connection glass run channel 150 to which the engagement member 200 is attached is transported, for example, the vehicle inner side wall portion 152 and the vehicle outer side wall portion 154 are displaced in a direction approaching each other. When the force in the direction of the arrow X1 of 4 (the width direction of the base portion 175) is applied, the first longitudinal locking portions 185 and 185 are displaced toward each other and fit into the longitudinal locking grooves 224 and 224. And hold the trunk 205. For this reason, the locking with respect to the engagement member 200 of the connection glass run channel 150 is maintained, and the engagement member 200 can be prevented from falling off.
The longitudinal locking projections 221 and 221 of the engaging member 200 are locked to the locking recesses 189 and 189 of the second longitudinal locking portions 188 and 188. Here, for example, the vehicle inner side wall portion 152 and the vehicle outer side wall portion 154 are displaced in directions away from each other, and a force in the direction of the arrow Y1 in FIG. 4 (the width direction of the base portion 175) acts on the connection glass run channel 150. In this case, the second longitudinal locking portions 188 and 188 are displaced toward each other and the locking between the longitudinal locking portions 188 and 188 and the locking projections 221 and 221 is strengthened. Etc. can be prevented.

As shown in FIG. 5, in the connection glass run channel 150, the width direction locking projections 222 and 222 of the engaging member 200 are arranged in the width direction on the recesses 196 and 196 of the first width direction locking portions 195 and 195. It is locked along. Here, for example, when the glass run product 100 is deformed in the longitudinal direction and a force in the direction of the arrow X2 in FIG. 5 (longitudinal direction of the base portion 175) acts on the connection glass run channel 150, the first width direction engagement is performed. The stoppers 195 and 195 are displaced toward each other and the locking parts 195 and 195 and the locking projections 222 and 222 are locked strongly, so that the engagement member 200 can be prevented from falling off.
Further, for example, when the glass run product 100 is deformed in the longitudinal direction and a force in the direction of the arrow Y2 in FIG. 5 (longitudinal direction of the base portion 175) acts on the connection glass run channel 150, the root support portion of the base portion 175 The step forming 168 sandwiches the base portion 210 (flat plate body 212) of the engaging member 200. In addition, the deformation of the base portion 175 is suppressed by disposing the base portion 210 made of a material harder than the base portion 175 to the base support portion 168 having the concave shape of the base portion 175 as in the present embodiment. be able to. For this reason, it is possible to effectively prevent the engagement member 200 from being displaced or dropped out.

As described above, when the connecting glass run channel 150 is deformed in the longitudinal direction or the width direction, the base portion 175 is deformed, and the outer peripheral end and inner peripheral end of the horizontal inner wall 177 and the vertical inner wall 179 are displaced. In some cases, the displacement of one inner wall may cause the other inner wall to be displaced at the same time.
For example, when the horizontal inner wall 177 and the vertical inner wall 179 are continuously formed as in the present embodiment, the vehicle inner side wall portion 152 and the vehicle outer side wall portion 154 are displaced in a direction approaching each other. The outer peripheral side end portions of the horizontal inner walls 177 and 177 are displaced in a direction away from each other, but the outer peripheral side end portions of the vertical inner walls 179 and 179 are drawn toward each other due to the displacement of the horizontal inner walls 177 and 177. On the other hand, when the outer peripheral side ends of the horizontal inner walls 177 and 177 are displaced in a direction approaching each other, the outer peripheral side ends of the vertical inner walls 179 and 179 are displaced in a direction away from each other.
Thus, the insertion hole 160 surrounded by the horizontal inner wall 177 and the vertical inner wall 179 typically deforms in the longitudinal direction and the width direction.
On the other hand, when the engaging member 200 is attached to the base portion 175 of the connection glass run channel 150, the first longitudinal locking portion 185 formed on the lateral inner wall 177 of the insertion hole 160 has the width of the engaging member 200. The first width direction locking portion 195 formed in the second longitudinal locking portion 188 and the vertical inner wall 179 is locked in the direction locking groove 224, ie, on the four sides of the trunk portion 205 of the engaging member 200. Locks to the longitudinal locking projection 221 and the width locking projection 222. Therefore, the displacement of the engagement member 200 with respect to the change (deformation) of the insertion hole 160 that may occur when the glass run channel assembly 105 (that is, the glass run product 100) including the engagement member 200 is transported. And omissions can be prevented in advance.

Next, the connection glass run channel 150 with the engagement member 200 attached thereto is mounted in the groove 32 formed at a predetermined position of the window frame 22 (inclined frame 58) while referring to the drawings. This will be described in detail.
FIG. 7 is a diagram showing a configuration of the front corner portion 16 where the front pillar side vertical side frame 63 and the inclined frame 58 intersect at a predetermined crossing angle, and the connection according to the first embodiment arranged in this portion. It is sectional drawing which looked at the glass run channel 150 from the vehicle outer side. FIG. 8 is a cross-sectional view taken along line VIII-VIII in FIG.
As shown in FIGS. 7 and 8, an engagement hole 40 as an engagement portion is formed in a portion corresponding to the protrusion 167 of the stopper 25 that is a window frame constituent member. The engagement hole 40 has a size that allows the protrusion 167 to be inserted (penetrated).

As shown in FIGS. 7 and 8, the engagement member 200 is attached to a predetermined position of the connection glass run channel 150 by inserting the trunk portion 205 into the insertion hole 160 and fitting the root portion 210 into the root support portion 168. It has been. Then, the projecting portion 167 including the projecting portion 165 and the trunk portion 205 is inserted into and engaged with the engaging hole 40 formed in the window frame 22, and the connection glass run channel 150 to which the engaging member 200 is attached is connected to the window frame. It is mounted in 22 grooves 32.
At this time, as shown in FIG. 8, the first longitudinal locking portion 185 is fitted and locked in the longitudinal locking groove 224 of the engaging member 200. The longitudinal locking protrusion 230 of the engaging member 200 is in contact with and locked to the lateral inner wall 177 of the inner wall that forms the periphery of the insertion hole 160. The longitudinal locking projection 221 of the engaging member 200 is locked to the locking recess 189 of the second longitudinal locking portion 188. Further, as shown in FIG. 7, the width direction locking projection 222 of the engaging member 200 is locked to the recess 196 of the first width direction locking portion 195. For this reason, in the connection glass run channel 150 mounted in the groove 32 formed at a predetermined position of the window frame 22 (inclined frame 58), the engaging member 200 is connected to the connection glass run channel 150 both in the longitudinal direction and in the width direction. Further, since the engagement member 200 is firmly locked, displacement of the engagement member 200 from the connection glass run channel 150, dropout, and the like are prevented.

In addition, as shown in FIG. 7, the connecting glass run channel 150 mounted on the inclined frame 58 extends in the longitudinal direction along the inclined frame 58 (particularly the direction in which the horizontal frame 56 or the center pillar side vertical side frame 61 is present). When a force to move (displace) is applied, the outer wall surface of the projecting portion 167, that is, the outer wall surface of the projecting portion 165 in this embodiment, abuts on the peripheral edge of the engagement hole 40. Since the projecting portion 167 has mechanical strength reinforced by the trunk portion 205 of the engaging member 200 fixed in the insertion hole 160, the movement of the connecting glass run channel 150 is restricted by the contact, and the position in the longitudinal direction is determined. Misalignment can be prevented. Here, although the intersecting angle θ between the rising direction of the protruding portion 165 and the stopper 25 of the present embodiment is perpendicular, the rising direction of the protruding portion 165 is determined so that the intersecting angle θ becomes an acute angle (that is, insertion) It is preferable to determine the direction in which the holes 160 are formed. By making the crossing angle θ an acute angle, it is possible to prevent the connecting glass run channel 150 from dropping from the stopper 25 during use.
In FIG. 7, reference numeral 112 denotes a base portion of the first glass run channel, reference numeral 114 denotes a vehicle inner side wall portion of the first glass run channel, and reference numeral 122 denotes a base portion of the second glass run channel. Reference numeral 124 denotes a vehicle inner side wall portion of the second glass run channel.

  As described above, in the connection glass run channel 150 to which the engagement member 200 according to the present embodiment is attached, the separate member formed in advance as the hard engagement member 200 is used. Unlike the case where the protrusion is integrally formed by injection molding in the molding die in which the insert member is inserted, the mechanical strength is excellent due to the easy operation of mounting the engaging member 200 at a predetermined position of the connection glass run channel 150. A protrusion 167 can be formed. And since the engagement member 200 should just be retrofitted to the base part 175 which comprises the main body of the connection glass run channel 150, the restrictions of the material and shape which comprise this engagement member 200 can also be reduced.

The shape of the protrusion is not limited to that of the above embodiment. For example, a modification example described below is given. FIG. 9 is a cross-sectional view schematically showing the structure and mounting state of the connection glass run channel 350 according to the second embodiment.
As shown in FIG. 9, the base portion 375 of the connection glass run channel 350 is provided with a protrusion 365 protruding from the outer peripheral surface. The protrusion 365 is formed in a shape that can be engaged with the engagement hole 40 of the window frame 22 (inclined frame 58). Further, the projection 365 is formed so that the engagement member 200 can be attached, and is engaged with the engagement hole 40 of the window frame 22 together with the trunk portion 205 of the engagement member 200 that is inserted into and attached to the insertion hole 360 described later. A projecting portion 367 is formed. Further, a root support portion 368 that supports the root portion 210 of the engagement member 200 when the engagement member 200 is attached is formed on the inner peripheral surface of the base portion 375 of the connection glass run channel 350. The root support portion 368 is formed in a concave shape that recedes in the outer circumferential direction from the inner peripheral surface of the base portion 375 and is formed in a shape corresponding to the outer shape of the root portion 210, and is at least one of the peripheral edges of the root portion 210. It is comprised so that it may contact | abut and support a part.
Here, the projection 365 is formed in a range corresponding to the root support portion 368 in the connection glass run channel 350, and an insertion hole 360 into which the trunk portion 205 of the engagement member 200 can be inserted is formed. In the present embodiment, the insertion hole 360 is a non-through hole that opens toward the inner peripheral side of the base portion 375 and closes the outer peripheral side of the protruding portion 365.
With this configuration, in addition to the same effects as in the case of the first embodiment, the insertion hole 360 does not penetrate, so that the protrusion 365 is difficult to deform and the deformation of the insertion hole 360 can be suppressed. Furthermore, since the insertion hole 360 does not penetrate the protrusion 365, it is possible to prevent water droplets from entering the groove of the connection glass run channel 350 from the periphery of the engagement member 200.

The shape of the engaging member is not limited to that of the above embodiment. For example, a modification example described below is given. FIG. 10 is a perspective view schematically showing the structure of the engaging member 400 according to the third embodiment. FIG. 11 is a cross-sectional view schematically showing the structure of the connection glass run channel 450 to which the engagement member 400 according to the third embodiment is attached.
As shown in FIG. 10, the engaging member 400 according to this embodiment includes a base portion 410 having a flat plate-like main body portion 412 and a misalignment prevention protrusion 414 similar to the engaging member 200 according to the first embodiment. Is provided.
On the other hand, the trunk 405 characterizing the engagement member 400 is a columnar body 407 having a longitudinal locking groove 424 and a longitudinal locking ridge 430 similar to the engagement member 200 according to the first embodiment. And a locking head 420 having a longitudinal locking protrusion 421 and a width locking protrusion 422. Furthermore, a width direction locking groove 426 is formed on the base portion 410 side of the columnar main body 407, and when the engaging member 400 is attached to the connection glass run channel 450, the locking groove 426 is formed. It can be locked with a second width direction locking portion 497 (convex portion 498) formed on the vertical inner wall 479 located on the inner peripheral side of the base portion 475 (see FIG. 11). Furthermore, a width direction locking protrusion that locks to the vertical inner wall 479 at the center in the protruding direction (rising direction) of the narrow surface of the columnar main body portion 407 (surface parallel to the short side of the flat plate-shaped main body portion 412). A strip 440 is formed. Note that the protruding portion 467 formed of the trunk portion 405 and the projection portion 465 inserted into the insertion hole 460 can be engaged with the engagement hole 40 formed in the window frame 22 (inclined frame 58).

  As shown in FIG. 11, in the connection glass run channel 450, the width direction locking projections 422 and 422 of the engaging member 400 are arranged in the width direction of the recesses 496 and 496 of the first width direction locking portions 495 and 495. It is locked along. Here, when a force in the direction of the arrow X3 or Y3 in FIG. 11 (longitudinal direction of the base portion 475) acts on the connection glass run channel 450, in addition to the same configuration as in the first embodiment, the locking groove 426 is further added. And by forming the width direction locking ridges 440, it is possible to better prevent the engagement member 400 from falling off when the base portion 475 of the connection glass run channel 450 is deformed in the longitudinal direction.
