Abstract

PROBLEM TO BE SOLVED: To obtain a tape for driving a window regulator capable of resisting even use under high-temperature environment for a prolonged term in constitution using the tape and the window regulator using the tape. SOLUTION: Engaging recessed sections 52 in which engaging holes 50 are formed to intermediate sections are formed to one surface of a main tape 38 at regular intervals, and a plurality of reinforcing cords 54 are buried in an intermediate section in the thickness direction. Engaging projecting sections engaged with the engaging recessed sections 52 and engaging teeth 48 engaged with the engaging holes 50 are formed integrally to a sprocket, on which the main tape 38 is wrapped, in response to the cords 54. Accordingly, since the engaging areas of the engaging recessed sections 52 and the engaging projecting sections are increased and stress is dispersed, the deformation of the peripheral sections of the engaging holes 48 due to creep strain can be prevented, thus improving durability.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a window regulator driving tape for raising and lowering a door glass, and a window regulator using the same.

[0002]

2. Description of the Related Art A conventional technique will be described below using a power window regulator as an example. Conventional power window regulators are mainly of the wire type or the sector type. The wire-type power window regulator has advantages in that it is lightweight and has excellent vehicle mountability, but on the other hand, it has disadvantages in that durability is high and the cost is high. On the other hand, the power window regulator of the sector type has advantages in that it is inexpensive and has excellent durability, but on the other hand, it has disadvantages in that the weight is heavy and the vehicle mountability is poor. In other words, the advantages of the wire system are disadvantageous to the sector system, and the disadvantages of the wire system are advantages of the sector system.

Therefore, a power window regulator having both advantages has been developed, and a so-called tape type power window regulator has been devised. An example of the configuration of this type of tape-type power window regulator will be briefly described. A main guide rail and a sub-guide rail are disposed in a side door with a door glass elevating direction as a longitudinal direction, and upper and lower ends of each guide rail. A main tape guide and a sub-tape guide, a main carrier plate and a sub-carrier plate, each of which is supported so as to be able to move up and down along each guide rail and a lower end of the door glass is fixed to each of the main tape guide and the sub-carrier guide A sprocket rotatably arranged near the middle of the sprocket and the sub guide rail, a power window motor that applies a driving force to the sprocket, and a main tape guide and a main carrier plate that is moved up and down by being wound around the sprocket. Main tape and one end Middle portion while being connected to the flop is configured to include a Sabutepu elevating the sub carrier plate by moving wound on the sub tape guide.

According to the above configuration, when the power window motor is driven forward or backward, the sprocket rotates forward or backward around its axis. For this reason, the main tape moves by receiving the driving force, and moves the main carrier plate up and down along the main guide rail. Accordingly, the sub-tape connected to the main tape moves, and the sub-carrier plate is moved up and down along the sub-guide rail. As a result, the door glass moves up or down.

[0005]

However, in the case of the above-described conventional tape-type power window regulator, the transmission of the driving force from the sprocket to the main tape is performed by the engagement formed at a predetermined interval on the outer peripheral portion of the sprocket. Since the engagement between the teeth and the engagement holes formed at predetermined intervals in the longitudinal direction of the main tape is performed, there is a problem that the peripheral edge of the engagement hole of the main tape is easily deformed.

That is, although the main tape has the feature of having a long service life, since it is made of a resin material, the creep strength (particularly, creep strength in a high-temperature environment) of the peripheral portion of the engagement hole is obtained. Has the property of being weak. Therefore, if the tape-type power window regulator is repeatedly used in a high-temperature environment for a long time,
Creep distortion occurs at the periphery of the main tape engagement hole,
Deformation may occur in the portion of the sprocket directly engaged with the engaging teeth.

In view of the above, it is an object of the present invention to provide a window regulator driving tape and a window regulator using the same in a configuration using a tape that can withstand use in a high-temperature environment for a long period of time. It is.

[0008]

According to the first aspect of the present invention, a sprocket which is rotated around an axis by being applied with a driving force is wound around the sprocket while being engaged therewith,
A window regulator drive tape made of resin and having flexibility to move the door glass up and down by moving, and a tape reinforcing core material is provided along a tape longitudinal direction at a substantially middle portion in a thickness direction of the tape. Further, on one surface of the tape, engaging protrusions formed at predetermined intervals on the outer peripheral portion of the sprocket are engageable, and engaging recesses with the core material as a back are formed at the same interval. Is formed.

According to the present invention having the above structure, when the sprocket is driven to rotate about its axis while the engaging concave portion of the tape is engaged with the engaging convex portion of the sprocket, the side surface of the engaging convex portion is rotated. The side surface of the engagement recess is pressed, whereby the driving force is transmitted. Therefore, the contact area between the engaging protrusion of the sprocket and the engaging recess of the tape increases, so that the stress acting on the engaging recess of the tape is dispersed. As a result, even if the tape for driving a window regulator according to the present invention is repeatedly used in a high-temperature environment for a long period of time, almost no creep distortion occurs in the engagement concave portion of the tape. Therefore, according to the present invention, it is possible to prevent the tape from being deformed and to withstand a long-term use in a high-temperature environment.

As described above, if the engaging recesses are formed at predetermined intervals on one surface of the tape, the strength of the tape is reduced. However, in the present invention, a tape reinforcing portion is provided at a substantially intermediate portion in the thickness direction of the tape. Since the core material is embedded along the longitudinal direction of the tape and the engagement recess is formed with the core material as the back, the strength of the tape is sufficiently ensured.

According to a second aspect of the present invention, there is provided a window regulator driving tape according to the first aspect of the present invention, wherein the engaging concave portion has a sprocket axial direction at an intermediate portion in the tape width direction of the engaging concave portion. It is characterized in that an engagement hole is formed in the intermediate portion so that the engagement tooth can be engaged.

According to the present invention having the above-described structure, in addition to the above-described engagement between the engagement concave portion and the engagement convex portion, the engagement hole formed in the intermediate portion of the engagement concave portion in the tape width direction is provided. Since the engaging teeth formed at the sprocket axial direction intermediate portion of the engaging convex portion are engaged, in addition to the stress dispersing effect due to the increase in the engaging area described above, the engagement state between the tape and the sprocket is further ensured. It can be. Therefore, according to the present invention, both the effect of preventing tape deformation and the effect of improving driving force transmission performance can be obtained.

According to a third aspect of the present invention, there is provided a window regulator according to the first or second aspect, and a driving force is applied to the sprocket around which the window regulator driving tape is wound. Driving means, a glass support coupled to the window regulator driving tape and supporting the lower edge of the door glass, and a guide rail arranged so that the door glass elevating direction is a longitudinal direction and slidably supports the glass support. And a guide means for guiding the window regulator driving tape so that the window regulator driving tape moves along a predetermined routing path.

According to the present invention having the above structure, when a driving force is applied to the sprocket from the driving means, the sprocket rotates around its axis. When the sprocket rotates, the sprocket rotates because the engaging concave portions formed at the same interval are wound around the engaging convex portions formed at predetermined intervals on the outer peripheral portion of the sprocket. The rotational force at this time is directly transmitted from the engaging projection to the engaging recess. Accordingly, the tape moves along a predetermined route while being guided by the guide means, and moves the glass support up and down along the guide rail. Since the lower edge of the door glass is supported by the glass support, when the glass support slides along the guide rail, the door glass is also raised and lowered.

Here, in the present invention, since the window regulator driving tape described in claim 1 or 2 is used, the effect of the invention described in claim 1 (deformation of the tape) is achieved. (Prevention Effect) Or the effects of the invention described in claim 2 (the effect of preventing tape deformation and the effect of improving driving force transmission performance) are directly utilized in the window regulator system. Therefore, according to the present invention, it is possible to obtain a highly durable window regulator that can sufficiently withstand use in a high-temperature environment for a long time.

Next, the main part of this embodiment will be described with reference to FIGS.

As shown in FIGS. 3 to 5, on one surface of the main tape 38, groove-shaped engaging recesses 52 are formed at predetermined intervals along the longitudinal direction of the tape. The cross-sectional shape of the engaging concave portion 52 in the direction perpendicular to the longitudinal direction is an equilateral trapezoidal shape. A substantially rectangular (barrel-shaped) engagement hole 50 is formed in the middle portion of each engagement recess 52 in the tape width direction. The groove-shaped engaging recess 52 is divided by forming the engaging hole 50, which is a through hole, at an intermediate portion in the tape width direction, and a pair of engaging recesses 5 are provided on both sides of the engaging hole 50.
No. 2 is formed.

Further, a plurality of cords 54 as "core members" are provided along the longitudinal direction of the tape on the back side of the pair of engaging concave portions 52 (that is, at a substantially middle portion in the tape thickness direction of the main tape 38). It is buried. These cords 54 are buried to reinforce the main tape 38, and in the present embodiment, three cords are buried on both sides in the width direction of the main tape 38 as one set.

According to the configuration of the main tape 38,
As shown in FIGS. 6 and 7, a plurality of engaging projections 56 are formed on the outer peripheral portion of the sprocket 34 at predetermined intervals in the circumferential direction. The cross-sectional shape of the engagement projection 56 is the engagement recess 5.
The cross-sectional shape is set to be the same as the cross-sectional shape of No. 2 and the pitch of both is also set to be the same. Further, the engagement hole 5 of the main tape 38 is provided at the intermediate portion of the engagement protrusion 56 in the sprocket axial direction.
The engagement teeth 48 that can be engaged with 0 are integrally formed. Therefore, the engaging projections 56 and the engaging teeth 48 of the sprocket 34
The engaging recess 52 and the engaging hole 50 of the main tape 38 are engageable, and the main tape 38 is wound around the outer periphery of the sprocket 34 in a state where both are engaged.

The main tape 38 constructed as described above
Are fixed to the main carrier plate 22 as follows. First, supplementing the configuration of the main carrier plate 22 itself, as shown in FIG. 8, the main carrier plate 22 is formed in a rectangular flat plate shape, and upper edges of both sides of the main carrier plate 22 are circular. A pair of glass mounting holes 58 and 6 each comprising a hole and a long hole.
0 is formed. Further, in the center of the rear side of the main carrier plate 22, a block-shaped slider (resin guide) 20 inserted into the guide rail 12 is provided with a bolt 62.
It is fixed at. The slider 20 is formed with a rail groove 64 having an L-shaped cross section for being inserted and fitted on the guide rail 12 and moving along the guide rail 12, and a linear cross section for attaching the main tape 38. Mounting groove 66 is formed. Further, the slider 20
On one surface of the mounting groove 66, an uneven portion 66A that matches the cross-sectional shape of the main tape 38 is integrally formed.
The main tape 38 is fitted into the uneven portion 66A (see FIG. 9). The main tape 38 and the slider 20
The method of joining (fixing) the main tape 38 to the slider 2 by outsert molding is not limited to the above.
It is also possible to adopt a method of fixing to 0.

In this embodiment, the main tape 38 having the substantially rectangular engaging hole 50 is used. However, in consideration of the fact that the guide rail 12 is curved in the longitudinal direction, the main tape 38 is substantially parallel. A main tape having a quadrilateral engagement hole may be used. In this case, it is preferable to use a sprocket in which the engaging teeth are inclined at a predetermined angle with respect to the circumferential center line.

The sub-tape 46 does not have the engaging hole 50 formed in the main tape 38 (see FIG. 1). Therefore, the intermediate portion 46 of the sub-tape 46
A is a lower tape guide portion 58 of the sprocket cover 36.
Although it is inserted into the inside, it does not engage with the engaging teeth 48 of the sprocket 34.

Next, the operation and effect of this embodiment will be described.

First, a method of manufacturing the main tape 38 will be described. As shown in FIG. 3 and FIG.
0, a convex portion 72 for forming the engaging concave portion 52 is formed.
Are formed at predetermined intervals. Further, the projection 72
A raised portion 74 for forming an engaging hole 50 that meshes with the engaging tooth 48 of the sprocket 34 is integrally formed at an intermediate portion of the sprocket 34. Then, first, the convex portion 7 of the lower mold 70 having the above configuration
A required number of cords 54 are provided on the top surface side of the second. In addition,
A predetermined tension is applied to the cord 54 in advance by being pulled at both ends of the lower mold 70, and strictly speaking, the cord 54 is held at a position slightly separated from the top surface of the projection 72. However, in order to prevent the cord 54 from approaching the formation surface side of the engagement concave portion 52 (the side that meshes with the sprocket 34) when the resin flows (resin molding), that is, to increase the cord holding force during the resin flow. Protrusions 7 at predetermined intervals
2, the cord 54 may be placed on the top surface. Next, the upper mold 76 is lowered to be in a state of facing the lower mold 70. Next, resin is injected into a gap 78 between the lower mold 70 and the upper mold 76. Then, if the resin is cured and then released, the main tape 3
8 are formed.

Next, the operation of the power window regulator 10 according to the present embodiment will be outlined. Door glass 2
When a power window switch (not shown) is operated to raise the motor 4, the motor body 32 of the power window motor 28 is driven to rotate forward. When the motor body 32 is driven to rotate forward, the sprocket 3 is driven via a gear mechanism (not shown).
4 rotates counterclockwise in FIG. Since the intermediate portion 38A of the main tape 38 is wound around the sprocket 34, when the sprocket 34 rotates counterclockwise, the rotational force at that time is generated from the engaging projection 56 and the engaging teeth 48 of the sprocket 34. The power is transmitted to the engaging concave portion 52 of the main tape 38 and the peripheral portion of the engaging hole 50. As a result, the main tape 38 is connected to the main upper tape guide 14.
And while being guided by the main lower tape guide 16,
The main carrier plate 22 is moved along the guide rail 12 by being moved in the arrangement direction (the direction of the arrow A).

Since the other end portion 46C of the sub tape 46 is connected to the main tape 38 by the clip 40, when the main tape 38 rotates counterclockwise in the closed loop and moves in the direction of arrow A, the sub tape 46 becomes the sub tape. While being guided by the guide 42, it is pulled (pulled) in the direction of its arrangement (the direction of the arrow A '). Accordingly, the sub-tape 46 moves in the direction of arrow A ', and raises the sub-carrier plate 44.

With the above operation, the door glass 24 is moved upward while being guided by the door glass sash 26, and the door glass is closed.

Conversely, to lower the door glass 24,
When a power window switch (not shown) is operated, the motor body 32 of the power window motor 28 is driven to rotate in the reverse direction. When the motor main body 32 is driven to rotate in the reverse direction, the sprocket 34 rotates clockwise in FIG. 2 via a gear mechanism (not shown). When the sprocket 34 rotates clockwise, the rotational force at that time is transmitted from the engaging projection 56 and the engaging tooth 48 of the sprocket 34 to the engaging recess 52 of the main tape 38 and the peripheral edge of the engaging hole 50. . As a result, the main tape 38 is connected to the main upper tape guide 14.
And while being guided by the main lower tape guide 16,
The main carrier plate 22 is moved along the guide rail 12 in the direction of the arrangement (the direction of the arrow B).

Since the other end 46C of the sub-tape 46 is connected to the main tape 38, when the main tape 38 rotates clockwise in the closed loop and moves in the direction of arrow B, the sub-tape 46 While being guided, it is pushed (pushed) in the direction of its arrangement (arrow B 'direction). Therefore, the sub-tape 46 moves in the direction of arrow B ', and lowers the sub-carrier plate 44. That is, the engaging concave portion 52 is provided in the sub tape 46 itself.
And the engagement hole 50 is not formed.
The sub-tape 46 does not move by directly receiving the driving force from the sprocket 34, but receives the driving force indirectly via the main tape 38 because the engaging protrusion 56 and the engaging teeth 48 of the Move in that direction. When the door glass 24 descends, its own weight is applied, so that the pressing force of the sub-tape 46 on the subcarrier plate 44 is reduced by the amount of the own weight. Conversely, the sub-tape 46 only needs to have a rigidity that takes into account the weight of the door glass 24.

With the above operation, the door glass 24 is moved downward while being guided by the door glass sash 24, and the door glass 24 is opened.

Here, in the present embodiment, the sprocket 3
The engaging projections 56 are formed at predetermined intervals on the outer peripheral portion of the main tape 38, and the engaging recesses 52 that engage with the engaging projections 56 are formed at predetermined intervals in the longitudinal direction of the main tape 38. When driven to rotate around the axis, the side surface of the engagement convex portion 56 presses the side surface of the engagement concave portion 52,
As a result, the driving force is transmitted. Therefore, the engaging protrusion 56 of the sprocket 34 and the engaging recess 52 of the main tape 38
Since the area of contact with the main tape 38 increases, the stress acting on the engaging recess 52 of the main tape 38 is dispersed. As a result, the main tape 38 of the present embodiment can be used for a long time under a high temperature environment.
Is repeatedly used, almost no creep distortion occurs in the engagement concave portion 52 of the main tape 38. Therefore, according to the present embodiment, it is possible to prevent the main tape 38 from being deformed, and to withstand a long-term use in a high-temperature environment.

As described above, if the engaging recesses 52 are formed at predetermined intervals on one surface of the main tape 38, the strength of the main tape 38 is reduced. A plurality of cords 54 for reinforcing the tape are buried along the longitudinal direction of the tape at a substantially middle portion in the direction, and the engaging recess 52 is formed with the cord 54 as a back. Is sufficiently secured.

Further, according to the present embodiment, in addition to the above-described engagement between the engagement recesses 52 and the engagement projections 56, the engagement holes formed in the intermediate portions of the engagement recesses 52 in the tape width direction. 50
Since the engaging teeth 48 formed at the intermediate portion of the engaging convex portion 56 in the sprocket axial direction are configured to be engaged,
In addition to the above-described stress dispersion effect due to the increase in the engagement area, the meshing state between the main tape 38 and the sprocket 34 can be further ensured. Therefore, according to the present embodiment, both the effect of preventing the deformation of the main tape 38 and the effect of improving the driving force transmission performance can be obtained.

[Second Embodiment] Next, a second embodiment of the window regulator according to the present invention will be described with reference to FIGS.

It is characterized in that the engaging recess 92 is formed over the entire length in the tape width direction. In this embodiment, the plurality of cords 54 are buried in the same manner as in the first embodiment, but the embedding position does not necessarily have to be the same as in the first embodiment. The cord 54 may be embedded in the middle part.

According to the configuration of the main tape 90,
As shown in FIG. 13, a plurality of engaging projections 96 are formed on the outer peripheral portion of the sprocket 94 at predetermined intervals in the circumferential direction. The cross-sectional shape of the engaging convex portion 96 is set to be the same as the cross-sectional shape of the engaging concave portion 92, and the pitch between them is also set to be the same. Therefore, the engaging concave portion 92 of the main tape 90 can be engaged with the engaging convex portion 96 of the sprocket 94, and the main tape 90 is wound around the outer peripheral portion of the sprocket 94 in a state where both are engaged. . However,
In the present embodiment, since the engaging holes 50 are not formed in the main tape 90, the engaging teeth 48 are not formed at the intermediate portion of the engaging protrusion 96 in the sprocket axial direction.

In this embodiment having the above-described structure, the procedure for manufacturing the main tape 90 is the same as that in the first embodiment. However, in the present embodiment, since the engagement holes 50 are not formed in the main tape 90, the protrusions 1 of the lower mold 98 are not provided.
No ridge 74 for forming the engagement hole 50 is formed in 00 (see FIG. 11).

The present embodiment is different from the first embodiment in that the engaging holes 50 are not formed in the main tape 90, but is otherwise the same.
Stress dispersion effect due to an increase in the engagement area between the
As a result, the effect of improving the durability of the power window regulator 10 by preventing deformation of the main tape 90 can be similarly obtained.

Further, in the case of the present embodiment, since the raised portion 74 for forming the engaging hole 50 is not formed in the convex portion 100 of the lower mold 98, there is no barrier that hinders the flow of the resin. Accordingly, the displacement of the cord 54 during resin molding is unlikely to occur, and the tension applied to the cord 54 can be reduced by changing the viewpoint.

In addition, in this embodiment, the main tape 9
Since the engaging hole 50, which is a through hole, is not formed at 0, the arrangement interval and the number of embedded cords 54 can be arbitrarily selected. Therefore, it is freely determined whether to set the degree of reinforcement of the main tape 90 or whether the strength distribution after reinforcement is made uniform in the tape width direction or intentionally made uneven. be able to.
