  Here, at least the base portion 12 and the pair of side wall portions 15 and 16 of the glass run channel material 10 are formed of a thermoplastic elastomer, and preferably the whole except for the rubber anti-slip member 30 described in detail later. Is formed of a thermoplastic elastomer. As the thermoplastic elastomer, a vinyl-based thermoplastic elastomer, a styrene-based thermoplastic elastomer, a urethane-based thermoplastic elastomer, or the like can be used. Preferably, when the olefin-based thermoplastic elastomer is used, the vehicle glass run channel material 10 can be reduced in weight, and the extrusion moldability and the bonding strength with the anti-slip member 30 can be kept good.

  An anti-slip member 30 made of foamed rubber (sponge rubber) is provided on the surface of the base portion 12 of the glass run channel material 10 facing the bottom surface portion 61 of the window frame 54 (the upper surface of the base portion 12 in FIG. 2). Are provided integrally. The anti-slip member 30 is a member that prevents the glass run channel material 10 from being displaced in the longitudinal direction with respect to the window frame 54 in a state where the glass run channel material 10 is mounted on the window frame 54. When the anti-slip member 30 is provided continuously along the longitudinal direction of the base portion 12, the anti-slip effect at each portion of the glass run channel material 10 becomes uniform, and the frictional force increases, which is preferable. In addition, the anti-slip member 30 has a larger contact area with the window frame 54, for example, a flat plate shape, even if a force causing the glass run channel material 10 to be displaced with respect to the window frame 54 is applied thereto. On the other hand, the frictional force generated is large, which is preferable.

  As shown in FIG. 2, the anti-slip member 30 is formed in such a thickness that the tip protrudes from the protrusions 13 a and 13 b in a free state. When the glass run channel member 10 is attached to the window frame 54, the anti-slip member 30 is compressed between the base portion 12 and the bottom surface portion 61 of the window frame 54 as shown in FIG. In contact with 61, a vertical load is applied and the frictional force is increased. For this reason, the protrusions 21 and 22 have a holding force sufficient to prevent the base portion 12 from being lifted from a predetermined position of the window frame 54 due to the restoring force of the anti-slip member 30 to return to the original shape. Set the shape.

Anti-slip member 30, the friction coefficient is large resin with the thermoplastic window frame 54 than the elastomer constituting the base portion 12 (including rubber, synthetic resin and thermoplastic elastomer) is a material, a first embodiment Then, it is made of rubber material. When the anti-slip member 30 is made of rubber, specifically, a solid rubber (non-foamed rubber) containing EPDM, a fine foam rubber having an expansion ratio of about 1.1 to 1.4, or an expansion ratio of 1.5. It is preferable to be a foamed rubber that can be formed of foamed rubber (sponge rubber) of about ˜5 and that is easy to compressively deform with a foaming ratio of about 2-3. The anti-slip member 30 of this embodiment is made of foamed rubber made of EPDM, has a width between the ridges 13a and 13b of the base portion 12, and in a free state, the window plate is closed with the window frame mounted ( 4 is a flat plate having a thickness of about twice the thickness in the state shown in FIG.
When solid rubber is used as the anti-slip member 30, the compression ratio of the thickness pressed against the bottom surface portion 61 of the window frame 54 when the anti-slip member 30 is attached to the window frame 54 is smaller than the foam rubber. By forming the thickness thinner than in the case of foamed rubber, the same effects as in the case of foamed rubber can be achieved.

  Here, in this specification, the coefficient of friction with the window frame of the anti-slip member is the coefficient of static friction with the surface of the window frame 54 that contacts the glass run channel material (assembly). For example, the window frame 54 of a typical opening / closing door of a vehicle is provided with the same coating film as the vehicle body exterior, that is, a coating film obtained by baking an acrylic resin or acrylic urethane resin paint, It means the friction coefficient with this coating film. For example, the friction coefficient of the anti-slip member 30 is preferably 1.5 or more, but more preferably 1.8 or more.

In this specification, the friction coefficient of the material constituting the anti-slip member and the anti-slip part described later is a static friction coefficient, which is measured by the following test method.
1. Two test pieces each having a width of 5 mm and a thickness of 2 mm made of a target material are prepared.
2. Prepare a flat metal jig with a test piece of 50 mm x 50 mm and a thickness of about 1 mm, so that two test pieces are parallel to one side of the jig with a gap of 30 mm on one side of the jig. Secure with double-sided tape.
3. A flat metal jig is placed on an acrylic resin paint coating plate with the surface on which the test piece is fixed facing downward, and a weight having a weight of 700 g is put on the flat metal jig together with the flat metal jig.
4). A flat metal jig is pulled in a direction perpendicular to the longitudinal direction of the test piece, and a load F ′ (N) when the sample starts to deviate from the coated plate surface is measured.
5. The coefficient of static friction is calculated from μ ′ = F ′ / w. Note that w is the total weight (N).

In the glass run channel material 10 of the present embodiment, the base portion 12 and the contact lips 18 and 19 are further in contact with the portion forming the inner surface of the channel portion 11a, that is, the sliding window plate 50 as shown in FIGS. Sliding material portions 28a, 28b, and 28c are formed on the surface to be formed. The sliding material portions 28a, 28b and 28c are layered portions (surface layer portions) formed of a material having a smaller coefficient of friction with respect to the window plate than the thermoplastic elastomer constituting the base portion 12 and the contact lips 18 and 19. The sliding material portions 28a, 28b, and 28c can be in a known form, for example, a coating layer formed by applying a coating agent mainly composed of nylon pile or urethane resin to each surface. good. Further, it may be a thermoplastic elastomer layer or an ultra-high molecular weight polyolefin composition layer having a hard component (thermoplastic resin component) more than the constituent material of the base portion 12 and both contact lips 18 and 19, and in this case, the base portion 12 and both contact lips 18 and 19 can be formed integrally with the sliding material portions 28a to 28c by coextrusion.

A mode in which the glass run channel material 10 is attached to the window frame 54 will be described with reference to FIG. In order to attach the glass run channel material 10 to the window frame 54, the glass run channel material 10 is inserted into the groove 11 of the window frame 54 from the base portion 12 while elastically deforming the front end sides of the side wall portions 15, 16 toward the channel portion 11 a side. The base portion 12 is opposed to the bottom surface portion 61 of the window frame 54, and the glass run channel material 10 is pushed in until the protrusions 13 a and 13 b come into contact with the bottom surface portion 61 of the window frame 54 while elastically compressing the anti-slip member 30. Can be installed. During this insertion operation, the projecting pieces 21 and 22 are elastically deformed in a direction approaching each other when abutting against the opening edge of the window frame 54, and cooperate with the elastic deformation of the side wall portions 15 and 16. Becomes smaller and is pushed in while sliding on the inner surface of the window frame 54. At the same time that the protruding pieces 21 and 22 pass through the retaining portions 65 and 66 of the window frame 54, the protruding pieces 21 and 22 are elastically restored toward the original shape, and the anti-slip member 30 is compressed by a predetermined amount. The glass run channel material 10 is held at a predetermined position of the window frame 54. In this state, the holding force of the projecting pieces 21 and 22 is set so that the glass run channel material 10 can be prevented from floating from the window frame 54 against the repelling force of the anti-slip member 30. As described above. Further, in this insertion work, the slip prevention member 30 does not contact the both side surfaces 62 and 63 of the window frame 54 and does not hinder the insertion workability. Regardless of the prevention member 30, it can be ensured satisfactorily.
In this state, the pressing force applied to the side wall portions 15 and 16 is released and brought into contact with the side surface portions 62 and 63 of the window frame 54, whereby the mounting of the glass run channel material 10 to the window frame 54 is completed.

  In the mounted state, the protruding piece 21 located on the inner side of the vehicle enters the concave portion and is locked by the retaining portion 65, and the protruding piece 22 positioned on the outer side of the vehicle is pressed against the side surface portion 63 and is retained. Locked to the portion 66. The base portion 12 and the side wall portions 15 and 16 form a channel portion 11a having a U-shaped cross section through which the window plate 50 can be inserted. The shielding lips 24 and 25 cover the tip portions of the side surface portions 62 and 63 of the window frame 54, shield the space between the vehicle glass run channel material 10 and the window frame 54, and design the design of these portions. Forming. In this state, the anti-slip member 30 is pressed against the bottom surface portion 61 of the window frame 54 in a compressed state.

Next, the state of the glass run channel material 10 when the window plate 50 is slid along the window frame 54 to which the glass run channel material 10 is mounted will be described with reference to FIGS.
4 shows a state in which the window plate 50 is closed in FIG. 3, and FIG. 5 is a transverse sectional view taken along line VV in FIG.
3 and 4, the glass run channel material 10 attached to the upper portion 54 a and the inclined portion 54 b of the window frame 54 has the window plate 50 below the uppermost position, that is, when the window portion is open. 50 and is kept in the state shown in FIG. When the window plate 50 is slid upward and approaches the uppermost position, the window plate 50 first comes into contact with both contact lips 18 and 19. Since both the contact lips 18 and 19 are elastically deformed, they elastically contact both surfaces of the window plate 50 and do not hinder the movement of the window plate 50.

When the window plate 50 further rises, the edge 50a of the window plate 50 contacts the base portion 12, and further presses the base portion 12 toward the bottom surface portion 61 of the window frame 54 (see FIG. 4). In a form in which the window plate 50 slides only in the vertical direction and the movement trajectory forms a straight line, the window plate 50 contacts both the contact lips 18 and 19 and contacts the base portion 12.
On the other hand, due to the characteristics of the elevating mechanism in the door, as shown by the arrow in FIG. 1, in the configuration in which the movement locus of the window plate 50 slightly slides behind the vehicle body (right in FIG. 1) in the vicinity of the uppermost position, FIG. As shown in FIG. 4, the window plate 50 moves in a direction along the longitudinal direction of the channel portion 11a (a direction orthogonal to the paper surface in FIG. 4) while being in contact with both the contact lips 18, 19 and the base portion 12. At this time, since the window plate 50 moves while rubbing the base portion 12 and both contact lips 18 and 19, a force acts to shift the glass run channel material 10 in the moving direction of the window plate 50.

  At this time, since the anti-slip member 30 is pressed against the bottom surface portion 61 of the window frame 54, the static frictional force of the glass run channel material 10 against the window frame 54 is increased. For this reason, even if the glass run channel member 10 receives a force that causes the glass run channel member 10 to be displaced in the same direction as the movement of the window plate 50 by the window plate 50, the glass run channel member 10 is not easily displaced relative to the window frame. Since the anti-slip member 30 is in a pressure contact state, the load in the right-angle direction, that is, the force pressing the base portion 12 against the bottom surface portion 61 of the window frame is increased, and the static friction force is increased in proportion thereto. . This static frictional force further increases as the right-angle load applied to the anti-slip member 30 further increases after the window plate edge 50a comes into contact with the base portion 12. In particular, the anti-slip member 30 is in close contact with the bottom surface portion 61 of the window frame 54 on the entire surface thereof, and has a large contact area, so that the static frictional force is large. Therefore, even in a configuration in which the movement trajectory of the window plate 50 is moved along the longitudinal direction while being pressed against the glass run channel material 10, the glass run channel material 10 is not easily displaced in the longitudinal direction with respect to the window frame 54, It is stably held at a predetermined position.

  In the present embodiment, both the contact lips 18, 19 and the base portion 12 are provided with the sliding material portions 28a to 28c, so that the frictional force acting on the window plate 50 and the contact lips 18, 19 is reduced, and the glass run is reduced. The force for shifting the channel material 10 in the longitudinal direction along the window frame 54 is reduced. For example, in the glass run channel material positioned at the inclined portion 54b of the window frame 54, when the edge 50a of the window plate comes into contact with the base portion 12, a part of the rising force of the window plate 50 is applied to the inclined portion 54b. It is converted into a diagonally upward force (force in a direction orthogonal to the paper surface in FIG. 3), and acts as a force for pushing the glass run channel material diagonally upward of the inclined portion 54b. However, when the sliding material portion 28a is formed on the surface of the base portion 12 as in the present embodiment, the edge 50a of the window plate is the sliding material when the edge 50a of the window plate 50 contacts the base portion 12. Since it easily slides on the portion 28a, the force for shifting the glass run channel material 10 along the inclined portion 54b of the window frame 54 is reduced. Therefore, the positional deviation of the glass run channel material 10 with respect to the window frame 54 is prevented satisfactorily. This action by the sliding material portions 28a to 28c can be satisfactorily prevented from positional deviation in the glass run channel material 10 disposed on the upper portion 54a, the front side portion 54c, and the rear side portion 54d.

  As shown in FIG. 4, the window plate 50 stops while the edge of the window plate 50 moves while further elastically deforming the base portion 12 and the anti-slip member 30, and is in the uppermost position, that is, the closed state. At this time, since the base portion 12 and the anti-slip member 30 are interposed between the bottom surface portion 61 of the window frame and the window plate 50, the impact on the window frame 54 is reduced, and the base portion 12 and Since collision energy is absorbed by elastic deformation of the anti-slip member 30, the generation of collision noise is prevented. In particular, when the anti-slip member 30 is made of a material that is easily elastically deformed, such as foam rubber, and has a large thickness, the effect of suppressing the occurrence of collision noise is high. When the window plate 50 is closed, the contact lips 18 and 19 are in contact with the window plate surfaces on both sides, and the glass run channel material 10 seals between the window frame 54 and the window plate 50.

  Further, as shown in FIG. 5, in the glass run channel material 10 provided on the side portions 54c and 54d of the window frame 54, the edge of the window plate 50 is always arranged at least in the longitudinal direction of the channel portion 11a. The window plate 50 is in contact with the contact lips 18 and 19. In this state, the window plate 50 slides along the longitudinal direction of the glass run channel material 10 (direction perpendicular to the paper surface in FIG. 5). Even in the side portions 54c and 54d of the window frame 54, the slip prevention member 30 is pressed against the bottom surface portion 61 of the window frame 54, and therefore, a force that prevents the glass run channel material 10 from being displaced relative to the window frame 54 is applied. Yes. Furthermore, if the sliding member 28a is also formed on the base portion 12, even if the edge 50a contacts the base portion 12 when the window plate 50 moves, it moves in contact with the sliding member portion 28a. The force to shift the glass run channel material 10 is reduced. Further, the sliding member portions 28b and 28c provided on the both contact lips 18 and 19 also reduce the force with which the sliding window plate 50 tries to displace the glass run channel member 10 in the longitudinal direction. For this reason, the position shift with respect to the window frame of the glass run channel material 10 is satisfactorily prevented also in the side part of the window frame.

  Accordingly, in the glass run channel material 10, the slippage preventing member 30 prevents the positional shift of the glass run channel material 10 with respect to the window frame in the longitudinal direction, that is, the direction along the window frame 54. Does not shift. For this reason, it is difficult for the corner portions (8, 9) to have a built-in compressive force or tensile force in the longitudinal direction, and no positional deviation from the window frame 54 occurs as shown in FIG. Therefore, the glass run channel assembly 1 is less likely to generate a compressive force or a tensile force due to slippage with respect to the window frame, and the detachment from the window frame 54 is satisfactorily reduced.

The glass run channel material according to the present invention can be manufactured by any method. For example, the thermoplastic elastomer portion and the rubber anti-slip member can be separately extruded and then integrated by adhesion or heat welding. In addition, the rubber anti-slip member is extruded and vulcanized in advance, and when the thermoplastic elastomer material is extruded, the anti-slip member is supplied into the extrusion mold and the two are fused and integrated. Also good. Further, by providing a production line for the thermoplastic elastomer portion following the production line for the anti-slip member, the vulcanized anti-slip member is supplied to the extrusion mold for the thermoplastic elastomer material, and the glass run channel material is provided. A glass run channel material can also be manufactured by a continuous process by carrying out welding integration.

(Second Embodiment)
The second embodiment shown in FIG. 6 is the glass run channel material 40 provided with the anti-slip members having different shapes in the glass run channel material 10 of the first embodiment, and therefore only different parts will be described. That is, the glass run channel material 40 according to the second embodiment has a layered structure made of solid rubber on the projecting surfaces of the protrusions 13a and 13b of the base portion 12 of the glass run channel material 40 in addition to the anti-slip member 30. Anti-slip members 41 and 42 are provided. In this embodiment, the ridges 13a and 13b can maintain a predetermined distance between the center of the base portion 12 and the bottom surface portion 61 of the window frame 54 in the same manner as described above, and further, the window frame 54 and the ridge 13a. , 13b can be increased. In particular, since the protrusions 13a and 13b are portions that are strongly abutted by the bottom surface portion 61 of the window frame 54, the glass run channel material 40 is attached to the window frame 54 by providing the anti-slip member 30 in this portion. Therefore, it is possible to make it difficult to shift the position.
In FIG. 6, the slip prevention member 42 on the outside of the vehicle also covers the surface pressed against the window frame 54 of the protruding piece 22 on the outside of the vehicle, and the protruding piece 22 is applied to the side surface portion 63 of the window frame 54. By press-contacting, a larger static frictional force can be generated between the window frame 54 and the slip suppression effect is further enhanced.

(Third embodiment)
7 and 8 show a glass run channel material 70 according to a third embodiment of the present invention mounted on a window frame 54. FIG. Also in the glass run channel material 70, the same parts as those in the glass run channel material 10 of the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted. The glass run channel material 70 includes an anti-slip member 71 extending to the base portion 12 and the ridges 13a and 13b on both sides thereof, and anti-slip portions 73, 74, and 75 provided to the protruding piece 21 and the shielding lips 24 and 25. It has.

The anti-slip member 71 of the third embodiment is made of a thermoplastic elastomer. That is, the anti-slip member 71 may be rubber, but can be formed of various resin materials that can be satisfactorily bonded to the base portion 12 such as a thermoplastic elastomer and that have a higher friction coefficient with respect to the window frame 54 than the base portion 12. Typically, such a resin material has rubber elasticity. Since the anti-slip member 71 only needs to have a larger coefficient of friction than the base portion 12, various thermoplastic elastomers such as vinyl, styrene, and urethane can be used like the base portion 12. The use of a thermoplastic elastomer having the same or similar SP value as that of the base portion 12 is preferable because the fixing strength can be easily increased by welding, and specifically, an anti-slip member having an olefin-based thermoplastic elastomer is preferable. 71 can be made lighter and stronger, which is preferable. Further, the glass run channel material 71 provided with the anti-slip member 71 made of thermoplastic elastomer does not require a vulcanization step, and therefore can be integrally formed by simultaneous extrusion molding and can be manufactured by a simpler manufacturing method. .

In the case of a thermoplastic elastomer, specifically, a durometer type A (Shore A) hardness specified in JIS K7215 is preferably 20 or more and 70 or less, that is, HDA 20 or more and 70 or less. If it is less than HDA20, the strength and durability tend to decrease. Moreover, when it exceeds HDA70, it is difficult to obtain a friction coefficient of 1.8 or more. Therefore, when it is HDA 20 or more and 70 or less, it has a strength capable of withstanding long-term use while exhibiting a good frictional force against the painted surface of a general window frame 54 used in a vehicle. More preferably, it is HDA 30 or more and 60 or less.
The coefficient of friction is preferably 1.5 or more, and more preferably 1.8 or more, as with the anti-slip member made of rubber.

  The anti-slip member 71 is fixed to the base portion 12 in a layered manner, and in a portion corresponding to the ridges 13a and 13b, a lip-like thin plate that protrudes from the both ends of the base portion 12 at a predetermined angle. It is formed in parts 71a and 71b. In this way, the anti-slip member 71 is fixed to the base portion 12 at the central portion in the width direction corresponding to the base portion 12, and both end portions in the width direction are provided so as to protrude away from the base portion 12 side. The slip prevention member 71 can be stably brought into contact with the frame 54.

  The anti-slip portions 73, 74, and 75 are provided in layers at portions where the glass run channel material 70 is pressed against the window frame 54, and thermoplastic elastomers of the base portion 12 and other portions of the glass run channel material. It is made of a resin material having a larger coefficient of friction than that. The anti-slip portions 73, 74, and 75 can be formed of rubber, thermoplastic elastomer, or the like, similarly to the anti-slip member, and it is preferable to select the same anti-slip material because it is easy to manufacture. Further, the anti-slip portion 73 is made of a material having a larger coefficient of friction with respect to the window frame 54 than the material of the protruding piece 21, the anti-slip portion 74 is made of a material of the shielding lip 24, and the anti-slip portion 75 is made of a material having a larger friction coefficient with respect to the window frame 54. It is formed. In the present embodiment shown in FIG. 7, the anti-slip member 71 and all the anti-slip portions 73, 74, 75 are integrally formed with the glass run channel material 70 by co-extrusion molding with the same olefin-based thermoplastic elastomer.

  The glass run channel material 70 can be attached to the window frame 54 in the same manner as the glass run channel material 10 of the first embodiment. In particular, since the anti-slip portions 73, 74, and 75 are portions that are not easily pressed against the side surface portions 62 and 63 of the window frame 54 when inserted into the window frame 54, workability is maintained well. 7 and 8, in a state where it is completely attached to the window frame 54, the slip prevention portion 73 is pressed against the retaining portion 65, and the slip prevention portions 74, 75 are pressed against the tops of the side surface portions 62, 63, respectively. Therefore, it is possible to prevent the displacement of the glass run channel material 70 in the longitudinal direction with respect to the window frame 54. The flaky portions 71a and 71b of the anti-slip member 71 are pressed against the window frame 54 and come into contact with the protrusions 13a and 13b. On the other hand, the center portion corresponding to the base portion 12 of the anti-slip member 71 is attached to the window frame 54 and the window plate 50 is not in contact with the base portion with respect to the window frame 54 as shown in FIG. It is separated or held in light contact.

When the window plate 50 ascends in the window frame 54 having the glass run channel material 70, the edge 50 a of the window plate 50 comes into contact with the base portion 12 and further presses the base portion 12 toward the bottom surface portion 61 of the window frame 54. (See FIG. 8). As a result, the base portion 12 is elastically deformed toward the bottom surface portion 61, and after the thin plate portions 71 a and 71 b first act as cushioning materials and are pressed against the bottom surface portion, the central portion of the anti-slip member 70 is the bottom surface portion. 61 is in pressure contact. By this elastic deformation, the energy of the window plate 50 can be absorbed, and the sound when the window plate 50 is pressed against the bottom surface portion 61 can be reduced well.
Further, when the window plate 50 slightly slides to the rear of the vehicle body (right in FIG. 1) in the vicinity of the uppermost position (closed position), the anti-slip portions 73, 74, Since both ends of 75 and the anti-slip member 71 are pressed against the window frame 54, the load applied to the anti-slip member is increased, the frictional force is increased, and the displacement of the glass run channel material 70 with respect to the window frame 54 is excellent. Is prevented. In particular, the slip prevention portions 74 and 75 of the shielding lips 24 and 25 can prevent the side walls 15 and 16 from moving due to the force along the longitudinal direction of the window frame 54 applied to the contact lips 18 and 19. It is possible to satisfactorily prevent the displacement of the run channel material 70 in the longitudinal direction.

(Fourth embodiment)
In the fourth embodiment, an anti-slip member 81 is provided in place of the anti-slip member 30 of the glass run channel material 10 of the first embodiment. The anti-slip member 81 is made of a thermoplastic elastomer and is formed in a shape that forms a hollow portion 83 with a surface of the base portion 12 that faces the window frame 54. As shown in FIG. 9, the anti-slip member 81 of the fifth embodiment includes a pair of side portions 81 b and 81 c that protrude from the base portion 12, and protrusions of both side portions 81 b and 81 c that are substantially parallel to the base portion 12. The hollow part 83 has a trapezoidal cross section. In this configuration, since the compressibility is imparted to the anti-slip member 81 by the hollow portion 83, the material strength of the anti-slip member 81 can be maintained and the same action and effect as in the case of foamed rubber can be obtained. In other words, the frictional force is favorably increased by the pressure contact with the window frame 54, and the positional deviation of the glass run channel material 80 can be satisfactorily suppressed. In particular, the sound generated when the window plate 50 is closed can be reduced more favorably as described above due to the elastic deformation of the hollow portion 83 between the window frame 54 and the window plate 50.

The anti-slip member 81 of this form can be integrally formed by simultaneous extrusion with the base portion 12 or the like, but can also be retrofitted to the glass run channel material.
In addition, the shape provided with the hollow portion between the base portion 12 as described above can be favorably applied to a material having a small degree of deformation due to compression, such as a solid rubber, in addition to a thermoplastic elastomer. In addition to the trapezoidal shape, the shape of the anti-slip member including the hollow portion 83 may be various shapes such as an oval, a rectangle, or a shape that is not symmetrical. The shape of the hollow portion 83 and the outer shape of the anti-slip member 81 are the same. The shape may not be.

The present invention is not limited to the above embodiment.
Various shapes are possible for the anti-slip member, and a plurality of anti-slip members may be provided or a plurality of different materials may be provided. For example, the configuration may be such that one end of the anti-slip member of the third embodiment, that is, the flaky member that protrudes from the both ends in the width direction of the base portion 12 toward the window frame 54 is provided only on one side. The structure affixed on the strip may be used. Further, the position of the anti-slip member 30 is not limited to the above-described form, and may be arranged so as to fill the space between the protruding piece and the window frame bottom face as long as the insertion operation is not hindered. Further, the anti-slip member is not limited to a continuous long one, but may be provided intermittently on the base.
The anti-slip portion is not limited to a form that is provided in a layered manner on the surface that is pressed against the window frame, and can be provided in various forms as long as the glass run channel material can maintain a predetermined strength. For example, it may be formed in a convex shape on the window frame contact surface of the shielding lip without forming a smooth surface. Further, in the third embodiment, the anti-slip portion is integrally formed by co-extrusion with the glass run channel material. However, a non-slip portion may be attached later with an adhesive or the like.
Similarly, when an anti-slip member or an anti-slip portion is provided on the injection molding corner member of the glass run channel assembly, it can be provided in various forms.

  The glass run channel assembly of the present invention and the window on which the glass run channel material is mounted may be provided in any part of the vehicle, and is provided in an open / close door such as a front part or a rear part or an arbitrary part of the vehicle body. Of course, a window is good. That is, in the present embodiment, the glass run channel material for the front door of the vehicle has been described, but the present invention can also be applied to a glass run channel material for the rear door, for example. Also in this case, the upper portion and the inclined portion of the glass run channel material may be formed of a continuous integrally molded product and be attachable to the window frame in a predetermined bending shape, or may have a plurality of same cross-sectional shapes. The glass run channel material may be formed by joining each end with a predetermined angle.

The sliding resistance of the glass run channel material according to the present invention was measured.
A test piece having the shape of the glass run channel material 70 having the shape shown in FIG. 7 was prepared by extrusion molding. In addition, about the base part 12 and both side wall parts 15 and 16, the olefin-type thermoplastic elastomer of the static friction coefficient 1.35 measured by the above-mentioned method is used, About the anti-slip member 71 and the anti-slip parts 73, 74, 75 Were the same materials and the following were used.
Example I: Olefin Thermoplastic Elastomer with Static Friction Coefficient 1.89, Durometer HDA Hardness 38 Example II: Olefin Thermoplastic Elastomer With Static Friction Coefficient 1.85, Durometer HDA Hardness 50 Comparative Example I: Static Friction Coefficient 1.35, Durometer HDA hardness 75 olefinic thermoplastic elastomer

Each test piece is mounted on a sash 91 having a cross-sectional shape shown in FIG. 10, and a glass plate having a thickness of 3.0 mm is inserted between the contact lips so that the sliding resistance of each test piece (70) to the sash 91 is increased. It was measured. The measuring method is as follows.
1. A test piece having a length of 100 mm was set in the center of a sash having a length of 300 mm, and a glass plate having a length of 200 mm and a thickness of 3.0 mm was inserted into the test piece.
A load of 2.0N, 10N, 20N, 30N, 40N, and 50N is applied from the glass plate toward the test piece, a string is placed on the test piece, and the wire is pulled at a speed of 10 mm / sec along the longitudinal direction of the sash. Measure the maximum load when starting to move. The measurement was performed 5 times with each load applied, and the average value (A) was determined.

3. A test piece having a length of 300 mm was set on a sash having a length of 300 mm. A glass plate having a length of 100 mm and a thickness of 3.0 mm was inserted into the test piece.
A load of 4.0 N (no load), 10 N, 20 N, 30 N, 40 N, and 50 N is applied from the glass plate toward the test piece, and the glass plate is slid 100 mm along the longitudinal direction of the sash at a speed of 150 mm / sec. Measure the sliding resistance. The maximum value and the minimum value of the sliding resistance between after 10 mm movement and after 90 mm movement were extracted, and the average value (B) was obtained.
5. The average value (A) is the force corresponding to the biting force of the test piece against the sash and the sliding resistance of the test piece against the glass, and the average value (B) is the sliding resistance of the test piece against the glass. The sliding resistance (F) of the test piece against the sash was determined by the following formula.
F (N / 100 mm) = A (N / 100 mm) −B (N / 100 mm)
Table 1 shows the sliding resistance against the sashes of Examples I and II and Comparative Example I.

この結果、実施例Ｉ，ＩＩと比較例Ｉを比較することにより、静摩擦係数が大きい材料よりなる滑り防止部材及び滑り防止部を備える試験片ほど摺動抵抗が大きいことがわかった。したがって、静摩擦係数が１．８以上である滑り防止部材及び滑り防止部を設けることにより、十分な位置ズレ防止機能を備えるガラスランチャンネル材が得られることが明らかとなった。また、特に、滑り防止部材及び滑り防止部の硬度が低い実施例Ｉでは、摺動抵抗力がより大きな値を示した。

As a result, by comparing Examples I and II with Comparative Example I, it was found that the sliding resistance of the test piece including the anti-slip member and the anti-slip portion made of a material having a large static friction coefficient was higher. Therefore, it has been clarified that a glass run channel material having a sufficient position shift preventing function can be obtained by providing a slip preventing member and a slip preventing portion having a static friction coefficient of 1.8 or more. In particular, in Example I in which the hardness of the anti-slip member and anti-slip part was low, the sliding resistance showed a larger value.

The degree of positional deviation when the glass run channel material according to the present invention was mounted on an actual vehicle was measured.
Extruded moldings having the same cross-sectional shape and material as in Example I and Comparative Example I are joined to injection molded corner members 8 and 9 as shown in FIG. 1 to produce glass run channel assemblies for vehicle doors, respectively. It was set as Example III and Comparative Example II. And it attached to the window frame of the vehicle door by the usual method.
Under the conditions of a temperature of 80 ° C. and a humidity of 95%, the operation of opening the window glass for 30 minutes after opening it for 30 minutes was moved up and down 300 times as one cycle. Then, the displacement amount from the position before raising / lowering of the window glass in site | part AF shown in FIG. 11 of a glass run channel assembly was measured. The results are shown in Table 2. As shown in FIG. 11, the amount of displacement is defined as + when shifted upward and / or right, and − when shifted downward and / or left.

この結果より、実施例ＩＩＩでは、いずれの部位においても変位量が１ｍｍ未満であったのに対し、比較例ＩＩでは、いずれの部位においても１ｍｍ以上、多いところで８ｍｍのズレがあった。このことから、実施例ＩＩＩは、繰り返し摺動抵抗を受けても、その位置ズレ防止機能が良好に作用しており、実際の使用状況においてもより適正な位置を保持し得ることが明らかとなった。

From these results, in Example III, the displacement amount was less than 1 mm in any part, whereas in Comparative Example II, there was a deviation of 8 mm in any part, where the displacement amount was 1 mm or more. From this, it is clear that Example III has a function of preventing misalignment even when it repeatedly receives sliding resistance, and can maintain a more appropriate position even in actual use conditions. It was.
