Description

  The present invention relates to a long guide strip that is mounted in a window frame of a vehicle and guides the lifting and lowering movement of a lifting window plate. The present invention also relates to a vehicle having a guide strip, a door panel, and other window frame structures.

In a window frame (including a case of a door frame) provided on a slide door, a front door, a rear door, etc. in a vehicle such as an automobile, a guide strip (typically a glass run, a glass run channel, a run channel, A guide strip (also referred to as a seal strip, guide member or the like) is provided. Then, the window plate rises in the window frame by the operation of the lifting mechanism provided in the panel having the window frame (for example, the door panel) to close the window, and conversely, the window is opened by lowering in the window frame. Sometimes, the guide strip is guided (guided) to the predetermined position of the window plate in which the guide strip moves up and down. Furthermore, the seal lip of the guide strip is elastically brought into contact with the surface of the window plate that moves up and down to seal between the window plate and the window frame, thereby preventing water and dust outside the vehicle from entering the vehicle.
A guide strip for such use is formed into a long and substantially groove shape from an elastic polymer material such as rubber mainly composed of EPDM and thermoplastic elastomer, and is mounted in a groove formed in a window frame.

By the way, when the vehicle travels on a rough road with irregularities on the road surface, the vehicle body rolls, and lateral acceleration accompanying the roll occurs. At this time, when the window plate is slightly lowered from the fully closed state (half open), the outer peripheral edge (typically the upper edge) of the window plate in the ascending / descending direction is removed from the guide strip groove and sealed. The window plate is not supported by the lip, and is supported by the seal lip only on two sides of the outer peripheral edges (typically, the front side and the rear side) on both sides in the direction parallel to the lifting / lowering direction. In such a state, an inertial force in the lateral direction of the vehicle body (in a direction orthogonal to the plane of the window plate) is generated in the window plate. The seal lip is elastically deformed toward the vehicle inner side and the vehicle outer side while maintaining a state in which the window plate is in contact with the surface of the seal lip while relatively swinging between the inner side and the vehicle outer side. For example, when the window plate further moves to the inside of the vehicle, the seal lip is pressed against the window plate, the seal lip instantaneously contacts the vehicle inner side wall at the deformation limit position on the vehicle inside, and the movement stops. For this reason, an unpleasant noise (collision sound) is generated at the moment when the window plate comes into contact with the side wall of the guide strip through the seal lip and collides with it.
For example, Patent Document 1 discloses a glass run for automobiles in which a hollow portion extending in the longitudinal direction is formed between a seal portion (sliding lip and extended lip) and a side wall as a measure for preventing such abnormal noise. Has been.

JP 2006-151059 A

However, according to the means for providing the hollow portion configured as described in the above-mentioned patent document, the positional deviation of the window plate is absorbed by the elastic deformation of the sliding lip and the extending lip supporting the tip. Therefore, for example, while the window plate moves to the inside of the vehicle, the displacement of the window plate is absorbed by the elastic repulsion force (force that pushes back the window plate) of the sliding lip inside the vehicle and the extended lip that supports the tip of the window. No collision sound. However, when the entire inner surface of the sliding lip comes into contact with the inner side wall of the vehicle, further elastic deformation of the sliding lip and the extended lip is prevented at this moment. Since the force increases and the window plate collides with the side wall of the vehicle interior via the seal portion, the above-described problem still cannot be solved satisfactorily.
The present invention has been created to solve the conventional problems related to the guide strip for a window frame of a vehicle, and prevents the seal lip from instantaneously contacting the side wall of the guide strip, so that the impact sound is not generated. It is an object of the present invention to provide a guide strip having a structure capable of preventing occurrence. Another object of the present invention is to provide a window frame structure such as a vehicle or a door panel provided with such a guide strip on a window frame.

In order to achieve the above object, the present invention provides a guide strip that is mounted on a window frame (typically a door frame) of a vehicle.
That is, the guide strip according to the present invention is mounted in a window frame of a vehicle to seal between the outer peripheral edge of the window plate and the window frame and guide the up-and-down movement of the window plate. It is a long guide strip.
When the guide strip according to the present invention is mounted at a predetermined position of the window frame, the guide strip is attached to the groove of at least one window frame arranged in parallel with the window plate ascending / descending direction. A bottom strip disposed at a position facing the end surface of the peripheral edge; a side strip projecting from at least one end in the width direction of the bottom strip toward the opening edge of the window frame; and a tip on the opening edge side of the side strip And a sealing lip made of an elastically deformable polymer material protruding continuously in a folded shape toward the center in the width direction of the bottom strip.
A tubular hollow portion having a hollow wall between the side strip of the guide strip and the sealing lip and having a hollow space that is closed at both ends in the longitudinal direction and filled with air is provided along the longitudinal direction. Has been placed. The hollow wall can be deformed in at least a part of the circumferential direction, and the tubular hollow portion can be reduced and restored.
The window plate contacts the seal ship and displaces the seal lip toward the side strip, and when the tubular hollow portion is pressed by the displacement, the volume of the hollow space is reduced. Accordingly, the air in the hollow space is compressed to increase the internal pressure, and the tubular hollow portion supports the seal lip from the back side by the expansion force, and the seal lip is prevented from colliding with the side strip. It is characterized by that.

In the guide strip of the present invention having such a configuration, the tubular hollow portion is disposed between the side strip and the seal lip, and both ends are closed along the longitudinal direction of the guide strip so that the inside is substantially filled with air. It is formed so as to have a sealed hollow space. When the seal lip is displaced to the side strip side by the movement of the window plate, the tubular hollow part is sandwiched between the seal lip and the side strip, and the volume of the hollow part space is reduced. The air is compressed, and an expansion force (repulsive force) is generated in the tubular hollow portion to restore the pressure before the internal pressure in the hollow space increases and the volume decreases.
When such an expansion force is generated, the vehicle body rolls and the window plate is instantaneously displaced (typically, a fraction of a second to a few tens of seconds) to the side strip side. In this case, the expansion force generated in the hollow space generates a cushioning action (buffering action) by air in the tubular hollow part, and the energy absorption amount is increased as compared with the conventional speed at which the window plate is displaced to the side strip side. Can be prevented. Also, in the initial state (the outer peripheral edge of the window plate is present in the guide strip and the lateral acceleration is not applied to the vehicle body), the seal lip or the side strip and the tubular hollow portion are not in contact or simply in contact with each other. The sealing lip or side strip is formed so as not to press the tubular hollow. Therefore, when the window plate moves up and down, an excessive pressing force is not applied to the window plate, so that an excessive sliding resistance is not generated between the window plate and the window plate is prevented from moving up and down.
Therefore, according to the guide strip of the present invention, by forming the tubular hollow portion, the window plate indirectly collides with the side strip through the seal lip (the displacement speed decreases instantaneously or becomes zero after contact). Can be prevented.) Thereby, generation | occurrence | production of a collision sound can be prevented, without preventing the raising / lowering movement of a window plate.

According to such a configuration, when a force for reducing the volume of the hollow space is instantaneously applied, not all of the air in the hollow space is instantaneously discharged to the outside, and the cushioning action by the air is maintained. Further, when the temperature rises in the use environment, the air is thermally expanded, but the air pressure in the hollow space is prevented from excessively rising. For this reason, the guide strip according to claim 2 can be applied to a wide range of usage environments.

Since the amount of air discharged per unit time is limited by the porous plug, momentary discharge of all air from the hollow space to the outside is prevented, and the hollow is not discharged. The air remaining in the subspace can be compressed to obtain a desired expansion force. In addition, when the force stops working, air flows into the hollow space from the outside, so that the internal pressure of the air in the hollow space and the external pressure can be kept the same without being affected by fluctuations in the ambient temperature. In addition, the shape of the tubular hollow portion can always be maintained in a preferable constant shape.

At the same time, the terminals are connected to each other.

Next, with reference to FIG. 3 to FIG. 5, the configuration and mounting form of the upper, front, and rear guide strips 52, 54, 56 of the guide strip 50 according to the present embodiment will be described. FIG. 3 is a cross-sectional view taken along line III-III in FIG. 1. Based on this figure, the cross-sectional shape of the rear guide strip 56 according to this embodiment and the window frame (here, the rear side) The window frame portion 17) will be described. Since the upper guide strip 52 and the front guide strip 54 have substantially the same configuration, a duplicate description is omitted. FIG. 4 is a longitudinal sectional view taken along the line IV-IV in FIG. 1 and is a view showing a configuration in the longitudinal direction of the tubular hollow portion 76 formed in the rear guide strip 56. FIG. 5 is a cross-sectional view taken along the line VV in FIG. 4 and shows the configuration of the lower end of the tubular hollow portion 76.
As shown in FIG. 3, the rear window frame portion 17 is formed by bending a metal strip so that the vehicle inner side wall 19 and the vehicle outer side wall 23 are arranged substantially parallel in the vehicle width direction. A groove 27 is formed between the two side walls 19 and 23 along a substantially vertical direction (a direction perpendicular to the paper surface of FIG. 3). A vehicle interior step portion 21 and a vehicle exterior step portion 25 are formed on the vehicle interior side wall 19 and the vehicle exterior wall 23 in order to lock a rear guide strip 56 described later.
On the other hand, as shown in FIG. 3, the rear guide strip 56 according to the present embodiment has a substantially U-shape (elongated before being attached to the groove 27) formed in a long shape by the extrusion molding of the polymer material described above. A main body 57 having a constant cross-sectional shape. The main body 57 is guided by the window frame 13 and is disposed at a position facing the end surface of the outer peripheral edge of the window plate 7 that moves up and down, and from both ends in the width direction of the bottom strip 58. The vehicle interior side strip 60 and the vehicle exterior side strip 70 project toward the center C (see FIG. 1) of the window opening 9 so as to form a groove 75, and an interior seal lip 62 described later. ing. The surface of the bottom strip 58 facing the end face of the window plate 7, the surface of the vehicle outer side strip 70, and the surface of the vehicle inner seal lip 62 facing the window plate 7 have lower static friction coefficients than the main body portion 57. The low friction material layer 64 is continuously formed in the longitudinal direction. Thereby, since sliding resistance with the window plate 7 can be reduced, the vertical movement of the window plate 7 becomes smoother. The low friction material layer 64 may also be applied to the back surface of the vehicle interior seal lip 62 and the surface of the tubular hollow portion 76 described later. As a result, it is possible to prevent abnormal noise when the vehicle interior seal lip 62 and the tubular hollow portion 76 leave after contact.

Further, as shown in FIG. 3, the rear guide strip 56 protrudes from the opening edge 29 side (protruding front end side) of the vehicle inner side strip 60 toward the center in the width direction of the bottom strip 58 and moves up and down. A vehicle interior seal lip 62 that is elastically contactable with the side surface of the window plate 7 and that extends in a folded manner while maintaining a space between the side strip 60 is integrally formed with the main body 57.
The rear guide strip 56 is formed such that the vehicle inner side locking piece 66 and the vehicle inner side shielding lip 68 project outward from the vehicle inner side side strip 60. Similarly, the vehicle outer side locking piece 72 and the vehicle outer side shielding lip 74 are formed so as to project outward from the vehicle outer side side strip 70. As a result, in the state where the rear guide strip 56 is mounted in the groove 27 of the rear window frame portion 17, it is prevented from coming out of the groove 27.

As shown in FIGS. 3 and 4, the rear guide strip 56 according to the present embodiment is provided between the inner side strip 60 and the inner seal lip 62 between the inner surface of the inner side strip 60 and the outer side of the vehicle. A tubular hollow portion 76 having a substantially semicircular cross-sectional shape protruding toward the side strip 70 side (window plate 7 side) is continuously provided along the longitudinal direction. The tubular hollow portion 76 is more flexible than the vehicle interior seal lip 62 (it is flexible in material, thinner than the vehicle interior seal lip 62, or flexible, or a combination thereof) ), A hollow wall 80 which can be deformed in part, and a hollow space 78 which will be described later. Thereby, when external force acts, the external shape and cross-sectional area of the tubular hollow part 76 can be reduced.
The hollow wall 80 constituting the tubular hollow portion 76 is extruded (co-extruded) so as to be continuous along the longitudinal direction simultaneously with the extrusion of the main body portion 57. When the hollow wall 80 and the vehicle interior side strip 60 are both molded from a compatible thermoplastic polymer material (thermoplastic resin, thermoplastic elastomer, etc.), the hollow wall 80 and the vehicle interior side strip 60 are At the end of the tubular hollow portion 76 in the width direction, they are integrated by heat fusion at the time of coextrusion molding. When both polymer materials are EPDM rubber, they are vulcanized and joined. In this case, the hollow wall 80 is preferably formed using natural rubber (NR), butadiene rubber (BR), styrene butadiene rubber (SBR), or a blended material thereof, which has higher bending resistance and airtightness than EPDM.

As shown in FIGS. 4 and 5, at both ends in the longitudinal direction of the tubular hollow portion 76 according to the present embodiment, the hollow wall 80 is joined to the vehicle interior side strip 60 so that the internal space 78 is substantially formed. Maintains a sealed joint. Both ends in the longitudinal direction of the tubular hollow portion 76 are closed, and a hollow space 78 filled with air whose pressure does not fall below 1 atm is formed between the hollow wall 80 and the vehicle interior side strip 60. Yes. In the tubular hollow portion 76, in the temperature range of about −30 ° C. to 80 ° C., when the function required for the tubular hollow portion 76 described later is not impaired, the outflow of the air in the hollow space 78 to the outside and the outside A structure in which the inflow of air from the inside is completely prevented may be used. However, when there is a possibility that the above function may be impaired, it is preferable to allow some air flow in a limited range between the inside of the hollow space 78 and the outside.
As the above-mentioned joining means, for example, a method of adhering and joining the contact portion between the hollow wall 80 and the vehicle interior side strip 60 using an adhesive, and fusing the contact portion with ultrasonic waves or high-frequency vibrations, etc. May be joined using known means such as a chemical joining method, a method of mechanically joining the inner side strip 60 with the hollow wall 80 sandwiched between separate clips or staples, etc. You may join together.

As will be described later, the hollow wall 80 has a structure having an elongation resistance (a force that resists expansion) that does not expand when the internal pressure of the hollow space 78 increases as the hollow wall 80 itself expands locally. Is preferred. In the rear guide strip 56 according to the present embodiment, the surface of the hollow wall 80 is flexible and is made of a material made of a material having a higher elongation resistance than that of the hollow wall 80 (typically a cloth entangled with artificial fibers or natural fibers). The sheet is made into a shape.) 82. The reinforcing layer 82 may be covered with a separately molded sheet, or may be formed by co-extrusion and laminated with a hollow wall. Further, by adjusting the material and thickness of the hollow wall without providing the above-described reinforcing layer 82, it is sufficient to push the vehicle interior seal lip 62 back to the window plate by the increased internal pressure expansion force in the hollow space 78. It is also possible to apply a hollow wall that has high strength and does not expand due to the expansion of the internal pressure.
The hollow wall 80 is preferably formed of a polymer material having higher flexibility, bending resistance, and airtightness than the material forming the vehicle interior seal lip 62. Thereby, while being able to improve the cushioning property of the tubular hollow part 76, since the air in the hollow part space 78 does not flow out through the hollow wall 80 unexpectedly, cushioning property is maintained stably. be able to.
Furthermore, it is preferable that the hollow wall 80 is formed of a polymer material with less fluctuation in hardness due to temperature change than the material forming the vehicle interior seal lip 62. Thereby, even when the temperature is low, the hollow wall 80 itself maintains flexibility, so that a good cushioning property can be maintained under a wide range of use environments.
In the state where the window plate 7 exists in the groove 75 of the rear guide strip 56, the hollow wall 80 and the back surface of the vehicle interior seal lip 62 are not in contact with each other, or the hollow wall 80 and the vehicle interior seal lip 62 are back surfaces. It is preferable to form the hollow wall 80 at a position where the hollow wall 80 does not press the inner seal lip 62 simply by contacting with each other. Accordingly, the sliding resistance between the seal lip and the window plate is not increased when the window plate is raised and lowered, and can be maintained appropriately.

Hereinafter, an example in which air is allowed to flow between the internal space 78 and the outside within a limited range will be described.
As shown in FIG. 4, compared with the cross-sectional area of a small hole (a general portion other than both end portions of the hollow space 78) which is a ventilation means according to the present embodiment at a predetermined position in the longitudinal direction of the tubular hollow portion 76. (Small holes having an extremely small cross-sectional area) 84 are formed so as to penetrate the hollow wall 80 and the vehicle interior side strip 60, and the air in the hollow space 78 passes outside through the small holes 84. A limited amount of spillage per unit time is possible. Instead of the above, as shown in FIG. 5, when a small groove 88 continuous in the longitudinal direction is formed at the time of extrusion molding, the longitudinal end of the hollow wall 80 is displaced and joined to the vehicle interior side strip 60. The small groove (gap) 88 of the ventilation means according to the present embodiment may be left along the width direction of the surface (joint surface) of the vehicle interior side strip 60 at the joint. Further, when the longitudinal end portion of the hollow wall 80 is displaced and joined to the vehicle interior side strip 60, the small hole portion (gap) 86 of the ventilation means according to the present embodiment is formed in the hollow wall 80 at the joint portion. It may be left on both ends in the width direction.
Here, in the ventilation means according to this embodiment, the amount of air flow per unit time between the inside and outside of the hollow space 78 is such that the end of the hollow space 78 is open (the hollow space is It is limited to orders of magnitude less than when it is not closed at all.

Next, the function (action and effect) of the rear guide strip 56 corresponding to the movement of the window plate 7 when the window plate is half-opened will be described in detail with reference to the drawings.
FIG. 6 shows a state in which surface force acts on the window plate 7 so that the window plate 7 is in an initial state (the window plate 7 indicated by a two-dot chain line in FIG. FIG. 7 is a cross-sectional view showing a state (window plate 7 represented by a solid line in FIG. 6) that is displaced from the vehicle width in a direction in which no acceleration in the direction is applied.

As shown in FIG. 6, when the vehicle body rolls and acceleration from the left side to the right side acts on the paper, an inertial force from the right side to the left side acts on the window plate 7. The window plate 7 presses the tubular hollow portion 76 toward the vehicle inner side strip 60 side via the vehicle inner side seal lip 62, thereby reducing the outer shape of the tubular hollow portion 76 and reducing the volume of the hollow space 78. The atmospheric pressure increases. At this time, when the hollow space 78 is sealed, air is not discharged to the outside. On the other hand, when the hollow wall 80 and the vehicle interior side strip 60 are provided with the small holes 84 that are ventilation means for restricting the amount of air discharged per unit time, the air in the hollow space 78 is removed. A small portion is discharged to the outside through the small hole 84, but the instantaneous discharge of all the air corresponding to the portion in which the volume in the hollow space 78 is reduced is prevented, and the hollow space 78 is substantially formed. Keep sealed. As a result, the air remaining in the hollow space 78 without being discharged is compressed to increase the internal pressure, and an expansion force (restoring force) is generated in the hollow space 78. The expansion force causes a cushioning action by air in the tubular hollow portion 76, and the tubular hollow portion 76 moves the vehicle interior seal lip 62 from the back side of the seal lip 62 (the vehicle interior surface of the seal lip 62) to the vehicle exterior. Press towards. Due to this cushioning action, a larger amount of energy absorption than before can be obtained, and the window plate 7 can be prevented from indirectly colliding with the vehicle inner side strip 60 via the vehicle inner seal lip 62. Thereby, generation | occurrence | production of a collision sound can be prevented effectively.
In consideration of the temperature range in which the rear guide strip 56 is normally used, when the temperature rises, the air thermally expands and the internal pressure in the hollow space 78 rises, but when the small hole 84 is formed. Since the air in the hollow space 78 is discharged to the outside through the small hole 84, the internal pressure in the hollow space 78 can be prevented from excessively rising.
On the other hand, when the window plate 7 moves to the outside of the vehicle and the pressing force against the inside seal lip 62 and the tubular hollow portion 76 does not act accordingly, the inside seal lip 62 moves to the original position by the restoring force. At the same time, since the atmospheric pressure in the hollow space 78 returns to an equilibrium state, the hollow wall 80 is restored to its original shape. Further, if the hollow wall 80 is formed of an elastic material, air flows into the hollow space 78 from the outside through the small hole 84 at the same time as described above.

In the present embodiment, the tubular hollow portion 76 is formed between the vehicle inner side strip 60 and the vehicle inner seal lip 62, but is not limited to such a form, and the opening of the vehicle outer side strip is not limited thereto. A vehicle exterior seal lip that protrudes integrally from the edge side toward the center in the width direction of the bottom strip and is elastically contactable with the side surface of the window plate that moves up and down, and extends in a folded manner while maintaining a space between the side strip and A tubular hollow portion may be formed between the vehicle outer side portion strip and the outer side portion strip. In this case, when the vehicle body rolls and the window plate is displaced to the outside of the vehicle due to momentary lateral acceleration applied to the window plate, the window plate is moved through the vehicle outer seal lip by the cushioning action of the tubular hollow portion. Indirect collision with the vehicle outer side strip can be prevented.
The functions (actions and effects) of the guide strip according to the present embodiment have been described above with respect to the rear guide strip 56, but other guide strips (the upper guide strip 52 and the front guide strip 54) that constitute the guide strip 50 are also described. It is the same.

The tubular hollow portion according to the first embodiment is not limited to that of the above-described embodiment.
Hereinafter, as a first modification of the tubular hollow portion, a preferred example of the tubular hollow portion in which a porous plug is provided as a ventilation means at the end in the longitudinal direction of the tubular hollow portion will be described with reference to the drawings. In the drawings for explaining the present modification, members and mechanisms that are substantially the same as those in the first embodiment are given the same reference numerals, and redundant explanations are omitted.

FIG. 7 is a partial longitudinal sectional view showing the configuration of the first modified example of the tubular hollow portion. FIG. 8 is a transverse sectional view taken along line VIII-VIII in FIG. 7 and shows a terminal of a first modified example of the tubular hollow portion.
As shown in FIGS. 7 and 8, a plug 183 of a porous material is attached to the end of the tubular hollow portion 176 in the longitudinal direction so as to close the tubular hollow portion 176, and thus the tubular hollow portion 176 has a hollow portion. A space 178 is formed, and unlike the first embodiment, the hollow wall 180 is not in contact with the vehicle interior side strip 60. The plug 183 is preferably fixed to the hollow wall 180 and the vehicle interior side strip 60 with an adhesive or the like. As the porous material, rubber, urethane sponge, lump of cotton, non-woven fabric or the like in which countless fine air holes are formed by open cells can be preferably applied. In this modification, the porous material plug 183 has an air flow rate per unit time of the end of the hollow space 178 so that a substantial hermetic state is maintained between the inside of the hollow space 178 and the outside. It is limited to be orders of magnitude less than when it is open. That is, the sum of the cross-sectional areas of the infinite number of air holes formed in the plug 183 of the porous material is considerably smaller than the cross-sectional area of the hollow space. With this configuration, the same effect as in the first embodiment can be obtained.

Further, in this modified example, when a vehicle having the guide strip 50 mounted on the window frame (door frame) 13 is used, the object can be achieved without being affected by fluctuations in ambient temperature (temperature increase and temperature decrease). . That is, when the temperature of the air in the hollow space 178 rises as the ambient temperature gradually increases and the volume of the air increases, the air in the hollow space 178 passes through the porous material plug 183. It can be discharged to the outside gradually. On the other hand, when the temperature of the air in the hollow space 178 is also decreased due to the gradual decrease in the ambient temperature and the volume of the air is reduced, the air can be gradually introduced into the hollow space 178 from the outside. . Thereby, the internal pressure of the air in the hollow space 178 and the external atmospheric pressure can be kept the same, and the tubular hollow portion 176 can always be kept in a preferable predetermined shape.
The porous material plug 183 may be provided so as to close both ends of the tubular hollow portion 176 in the longitudinal direction, or either one of the terminals is closed by another means and the other terminal is closed by the plug 183. May be provided. Further, in a state where the rear guide strip 56 is attached to the window frame 13, a porous material plug 183 may be disposed at the end of the tubular hollow portion 176 at the lower end in the longitudinal direction of the rear guide strip 56. As described above, the tubular hollow portion according to this modified example has a simple structure in which a plug of a porous material is provided in the tubular hollow portion, so that a guide strip having the above-described effects can be manufactured more easily.

  Next, as a second modification of the tubular hollow portion, a preferred example of the tubular hollow portion in which a check valve is provided as a ventilation means at the end in the longitudinal direction of the tubular hollow portion will be described with reference to the drawings. In the drawings for explaining the present modification, members and mechanisms that are substantially the same as those in the first embodiment are given the same reference numerals, and redundant explanations are omitted.

  FIG. 9 is a partial cross-sectional view showing a configuration of a second modification of the tubular hollow portion. FIG. 10 is a cross-sectional view taken along line XX in FIG. 9 and is a cross-sectional view showing the configuration of the terminal of the second modification of the tubular hollow portion. As shown in FIGS. 9 and 10, the longitudinal end of the tubular hollow portion 276 allows air to flow into the tubular hollow portion 276 from the outside, but prevents momentary outflow of air to the outside. A check valve 281 is mounted, whereby a hollow space 278 is formed in the tubular hollow portion 276. Here, the check valve 281 is formed such that the cross-sectional shape thereof is a reduced external shape (here, substantially semicircular) similar to the shape surrounded by the hollow wall 280 and the vehicle interior side strip 60. The tube portion 285 is provided with a vent hole 286 through which air can flow in and out along the longitudinal direction. One end of a movable lid 282 capable of opening and closing the vent hole 286 is connected to the hollow portion space 278 side of the cylindrical portion 285 and the inner side strip 60 side via a flexible connecting portion 284. The movable lid 282 is configured to close the vent hole 286 formed in the cylindrical portion 285 when closed, and to open the vent hole 286 when the movable lid 282 is opened. When the internal pressure of the air in the hollow space 278 and the external atmospheric pressure are the same, the movable lid 282 is closed or kept in a slightly open position as shown in FIG. The check valve 281 is manufactured separately from the guide strip, and is inserted into the tubular hollow portion of the guide strip.

With this configuration, as in the case of the first embodiment, the window plate 7 presses the tubular hollow portion 276 via the vehicle interior seal lip 62 by applying an instantaneous in-vehicle direction force to the window plate 7, so that the hollow The volume in the subspace 278 decreases. At this time, a part of the air in the hollow space 278 is instantaneously discharged to the outside through the vent hole 286 formed in the check valve 281, but is prevented from being discharged when the movable lid 282 is closed. Is done. On the other hand, when the movable lid 282 is slightly opened, the movable lid 282 is displaced to the cylinder portion 285 side by the wind pressure when a part of the air is discharged to the outside (in the direction of the arrow Y) and closes the vent hole. The closed state is maintained by the increased internal pressure described later. As a result, momentary discharge of the air in the hollow space 278 to the outside is prevented (however, when the guide strip is used, the temperature rises and the air expands and the volume increases, so the movable lid A slight amount of air is allowed to be discharged from the gap at the contact portion between 282 and the cylindrical portion 285.) The air remaining in the hollow space 278 without being discharged is compressed to increase the internal pressure, and an expansion force is generated in the hollow space 278. Due to the action of the expansion force, the tubular hollow portion 276 is cushioned by air and presses the displaced inner seal lip 62 toward the outer side of the vehicle. Indirect collision with the inner side strip 60 can be prevented.
On the other hand, when the window plate 7 is displaced to the outside of the vehicle and the force that presses the tubular hollow portion 276 is no longer applied, the inside seal lip 62 and the hollow wall 280 are returned to their original positions by the elastic restoring force. At this time, when the atmospheric pressure in the hollow space 278 becomes lower than the outside, the movable lid 282 opens (in the direction of the arrow X) by the action of negative pressure and / or by the elastic restoring force of the connecting portion 284 formed in the check valve 281. Air flows into the hollow space 278.
Also in this modified example, as in the first modified example described above, when using a vehicle in which the guide strip 50 is mounted on the window frame (door frame) 13, the object is not affected by the change in the temperature of the usage environment. Can be achieved.

In addition, in the check valve in this modified example, the check valve is not limited to an example using a movable lid. As shown in FIG. 11, instead of the movable lid 282 of the check valve 281 described above, the edge of the circular vent hole 286 (terminal edge in the direction facing the center side of the hollow space 278) is contacted and separated. A check valve 281A including a movable ball 283 that opens and closes the vent hole 286 may be used. The check valve 281A is composed of a separately formed cylindrical portion 285 and a movable ball 283 having a diameter larger than the inner diameter of the vent hole 286, and is mounted on the end of the tubular hollow portion 276 in the vertical direction in the direction of gravity. The ball 283 always contacts the edge of the vent hole 286 by its own weight and closes the vent hole 286. In the check valve 281A, when the air is discharged from the hollow space 278, the movable ball 283 contacts the edge of the air hole 286 on the hollow space 278 side and closes the air hole 286. Prevent instantaneous discharge to the outside. On the other hand, when air flows into the hollow space 278 from the outside, the movable ball 283 floats to open the vent hole 286, and air flows into the hollow space 278. With this configuration, the same effect as in the first embodiment can be obtained.
The check valve is preferably provided only at the lower end of the gravity direction in the longitudinal direction of the tubular hollow portion. When the check valve is provided only at the lower end, the upper end in the longitudinal direction of the tubular hollow portion is closed. As described above, the tubular hollow portion according to this modified example has a simple structure in which a check valve is provided in the tubular hollow portion, and therefore, a guide strip having the above-described effects can be manufactured more easily. Further, it is preferable that the cylindrical portions of the check valves 281 and 281A are fixed to the hollow wall 280 and the vehicle interior side strip 60 with an adhesive or the like as in the first modification.

  In any of the above-described embodiments, the tubular hollow portion is formed integrally with the guide strip. However, the present invention is not limited to such a form, and the guide strip is formed using a separately formed tubular hollow portion. It may be in the form of being attached to. FIG. 12 is a partial cross-sectional view showing a guide strip according to the second embodiment of the present invention. In the drawings for explaining the present embodiment, members and mechanisms that are substantially the same as those of the first embodiment are denoted by the same reference numerals, and redundant description is omitted.

  As shown in FIG. 12, the guide strip 350 according to the present embodiment protrudes from the portion of the vehicle inner side strip 60 near the bottom strip (see FIG. 3) toward the vehicle outer side strip (see FIG. 3). The first ridge portion 371 and the second ridge portion 373 projecting from the rear surface on the front end side of the vehicle interior seal lip 62 toward the vehicle interior side strip 60 are a main body portion (see FIG. 3). A gap is provided between the first protrusion 371 and the second protrusion 373 which are integrally molded. A tubular hollow portion 376 having a substantially elliptical cross-sectional shape, which will be described later, is fitted into the space between the vehicle interior seal lip 62 and the vehicle interior side strip 60. At this time, since the vehicle interior seal lip 62 can be expanded in a direction away from the vehicle interior side strip 60, the operation of fitting the tubular hollow portion 376 is easy. Further, since the fitted tubular hollow portion 376 is held by the first projecting portion 371 and the second projecting portion 373, the tubular hollow portion 376 is prevented from coming off, and the tubular hollow portion 376 is prevented from being removed from the vehicle interior side strip 60 and the vehicle interior seal lip. 62 can be stably locked between the two. In addition, the 1st protrusion part 371 and the 2nd protrusion part 373 may be contacting, and the front-end | tip may overlap.

  The guide strip 350 according to the present embodiment does not require the tubular hollow portion 376 to be integrally formed at the same time as the extrusion of the guide strip 350, and thus functions required for the tubular hollow portion 376 (flexibility, flexibility, airtightness). Can be molded with high quality by using a material having optimal properties. That is, when the tubular hollow portion is formed integrally with the guide strip, the molding conditions of the material for forming the guide strip (typically, the molding temperature and vulcanization temperature and time) and the tubular hollow portion are determined. Although it is necessary that the molding conditions of the material to be molded are the same or approximate, the guide strip 350 according to the present embodiment is a suitable method using a suitable material without being restricted by the molding conditions described above. The tubular hollow portion 376 can be formed under conditions. And the process of the terminal of the tubular hollow part 376 can be performed using the various means mentioned above and another means. With this configuration, in addition to the same effects as in the case of the first embodiment, a high-quality tubular hollow portion can be obtained using the optimum conditions and method without being restricted by the method and conditions for forming the tubular hollow portion. .

  In the second embodiment described above, the tubular hollow portion 376 formed separately is inserted into the vehicle interior seal lip 62 while being expanded, but the present invention is not limited to such a form and is formed separately. The tubular hollow portion may be fitted from one end in the longitudinal direction of the guide strip. FIG. 13 is a partial cross-sectional view showing a guide strip 450 according to a modification of the second embodiment of the present invention. In the drawings for explaining the present embodiment, members and mechanisms that are substantially the same as those of the first embodiment are denoted by the same reference numerals, and redundant description is omitted.

  As shown in FIG. 13, the guide strip 450 according to this modification is a vehicle that extends in a zigzag shape from the front end side of the vehicle interior seal lip 62 toward the vehicle interior side strip 60 and is connected to the vehicle interior side strip 60. The inner surrounding lip 463 is formed to be thinner and more flexible than the seal lip 62 and the vehicle inner side strip 60, and is integrally formed with the main body (see FIG. 3). Therefore, the surrounding lip 463 is easily reduced in a folded shape or expanded in a straight line when an external force is applied. The guide strip 450 includes an internal space 465 formed by being surrounded by the vehicle inner side strip 60, the vehicle inner seal lip 62, and the vehicle inner surrounding lip 463. The above-described separately formed tubular hollow portion 376 is inserted from one end in the longitudinal direction of the guide strip 450 into an inner space 465 formed between the vehicle inner side seal lip 62 and the vehicle inner side side strip 60 and is fitted. It is crowded. With this configuration, in addition to the same effect as in the case of the first embodiment and the effect described above based on FIG. 12, in the guide strip 450 according to the present modification, the tubular hollow portion 376 has the vehicle interior seal lip 62, By being surrounded from the outside by the vehicle inner side strip 60 and the vehicle inner surrounding lip 463, the risk of the tubular hollow portion 376 not being in direct contact with an external object and being damaged is reduced.

  In any of the above-described embodiments, the tubular hollow portion is formed separately from the vehicle interior seal lip. However, the present invention is not limited to such a configuration, and a part of the hollow wall of the tubular hollow portion is disposed on the vehicle interior side. It may be used as a seal lip. FIG. 14 is a cross-sectional view showing a guide strip according to a third embodiment of the present invention. In the drawings for explaining the present embodiment, members and mechanisms that are substantially the same as those of the first embodiment are denoted by the same reference numerals, and redundant description is omitted.

  As shown in FIG. 14, the guide strip 550 according to this embodiment has a tubular hollow portion 576 having a substantially semicircular cross-sectional shape that protrudes from the vehicle inner side strip 60 toward the vehicle outer side strip 70. It is integrally molded with the part 57. The tubular hollow portion 576 includes a hollow wall 580, and the hollow wall 580 at a portion facing the surface of the window plate 7 functions as the vehicle interior seal lip 62 (see FIG. 3) according to the first embodiment. And the process of the terminal of the longitudinal direction of the tubular hollow part 576 can be performed using the various means mentioned above and another means.

With this configuration, as in the case of the first embodiment, when an instantaneous inertia force in the vehicle interior direction is generated in the window plate 7 and the window plate 7 presses the hollow wall 580 toward the inside of the vehicle, the hollow of the tubular hollow portion 576 is formed. Since the volume of the partial space 578 is reduced, the air in the space 578 is compressed to increase the internal pressure, and an expansion force is generated in the hollow space 578. The tubular hollow portion 576 is cushioned by air due to the expansion force, and the hollow wall 580 presses the window plate 7 toward the outside of the vehicle, so that the window plate 7 passes through the hollow wall 580 and the vehicle inner side side strip 60. Indirect collision can be prevented.
As described above, according to the guide strip 550 according to the present embodiment, the window plate 7 can be indirectly connected to the vehicle inner side strip 60 by using a part of the hollow wall 580 of the tubular hollow portion 576 as the vehicle inner seal lip. Therefore, it is possible to effectively prevent the generation of a collision sound. Further, in the present embodiment, since there is no separate vehicle interior seal lip, the volume of the hollow space 578 can be relatively increased, and the cushion function can be more effectively exhibited.

  In any of the above-described embodiments, the guide strip has a tubular hollow portion only on the inside of the vehicle. However, the present invention is not limited to this form, and the guide strip has a tubular hollow portion on both sides of the vehicle inside and the vehicle outside. It may be. FIG. 15 is a cross-sectional view showing a guide strip according to a fourth embodiment of the present invention. In the drawings for explaining the present embodiment, members and mechanisms that are substantially the same as those of the first embodiment are denoted by the same reference numerals, and redundant description is omitted.

As shown in FIG. 15, the guide strip 650 according to the present embodiment integrally protrudes from the opening edge 29 side (protruding tip side) of the vehicle outer side side strip 70 toward the center in the width direction of the bottom strip 58 and moves up and down. A vehicle exterior seal lip 662 that can be elastically contacted to the side surface of the window plate 7 and that extends in a folded manner while maintaining a space between the side strip 70 is integrally formed with the main body 57.
In the guide strip 650 according to this embodiment, a vehicle interior tubular hollow portion 676 is formed between the vehicle interior side strip 60 and the vehicle interior seal lip 62. The tubular hollow portion 676 includes an arcuate hollow wall 680 that protrudes from the inner surface of the vehicle inner side strip 60 to the vehicle outer side and is connected to the tip side portion of the vehicle inner seal lip 62 so as to be continuous in the longitudinal direction. 678 is formed. The end of the tubular hollow portion 676 in the longitudinal direction can be processed using the various means described above and other means. An exterior tubular hollow portion 686 is also formed between the exterior side strip 70 and the exterior seal lip 662, and the tubular hollow portion 686 includes an arcuate hollow wall 690, and a hollow space 688 is formed. Is formed. The hollow walls 680 and 690 may be co-extruded integrally with the main body 57, or may be separately molded by extrusion or the like and fixed to the seal lip and the side strip with an adhesive or the like. Good. Further, the shape of the hollow walls 680 and 690 is not limited to the above shape, and may be, for example, a linear shape.

With this configuration, when the window plate 7 is displaced to the inside of the vehicle in addition to the displacement to the inside of the vehicle, the window plate 7 is indirectly indirect via the vehicle outside seal lip 662 due to the cushioning action by the air of the outside tubular hollow portion 686. Thus, it is possible to prevent the vehicle from colliding with the outer side strip 70.
As described above, according to the guide strip 650 according to the present embodiment, not only the window plate 7 does not collide with the vehicle inner side strip 60 but also the vehicle plate 7 prevents the collision with the vehicle outer side strip 70. Therefore, it is possible to effectively prevent the collision sound generated by the collision.
In the present embodiment, the various tubular hollow portions described above can be appropriately selected and used.

Although various embodiments relating to the present invention have been described above, all of the above-described embodiments are sashes (that is, a strip steel sheet is bent into a predetermined cross-sectional shape, for example, the shape shown in FIG. 3, by a cold roll forming method. The present invention relates to a guide strip formed on a sash door frame (window frame) made of a long material), but the present invention is not limited to application to such a sash door. The invention is also suitably applied to a press door frame (window frame) in which a portion corresponding to the window opening is punched out and the remaining part forms a door frame integrated with the door panel.
For example, the guide strip 50 according to the first embodiment described above can be preferably applied to the press door frame 14. FIG. 16 is a cross-sectional view showing an example (fifth embodiment).

As shown in FIG. 16, the guide strip 50 according to the present embodiment is mounted in the groove 27A of the press door frame 14 as in the first embodiment.
With this configuration, as in the case of the first embodiment, when an instantaneous lateral inertia force is generated in the window plate 7 and the window plate 7 is displaced toward the vehicle interior, the tubular hollow portion 76 is cushioned by air. It is possible to prevent the window plate 7 from indirectly colliding with the vehicle interior side strip 60 via the vehicle interior seal lip 62.
In addition, since this invention is not characterized by the structure of a press door frame, the detailed description beyond this is abbreviate | omitted. The parts denoted by reference numerals in the figure will be briefly described as follows. That is, reference numeral 19A denotes a vehicle inner side wall, reference numeral 21A denotes a vehicle inner side step part, reference numeral 23A denotes a car outer side wall, and reference numeral 25A denotes a car outer side step part.

  As mentioned above, although the specific example of this invention was demonstrated in detail, referring drawings, these are only illustrations and do not limit a claim. The technology described in the claims includes various modifications and changes of the specific examples illustrated above. For example, after extruding the body portion of the guide strip, a hollow wall may be formed between the vehicle interior side strip and / or vehicle exterior side strip of the guide strip and the seal lip. Moreover, the cross-sectional shape of the tubular hollow portion is not limited to the above shape, and may be a circle, a triangle, a quadrangle, or the like.
