As a mechanism for vertically moving the window glass of an automobile door, a carrier plate which is connected to a regulator and a guide rail mounted in the door and is slidable on the guide rail is attached to a lower portion of the window glass, and further. The carrier plate is attached to a wire linked to the regulator. The above-mentioned carrier plate usually uses a steel plate as a substrate, and a portion corresponding to the above-mentioned holding portion of the guide rail, the wire holding portion, etc. is cut and raised from the steel plate which is the substrate, and the bent portion is formed. Is covered with a synthetic resin to form the holding portion and the holding portion.

However, in covering the cut-and-raised bent portion of the steel plate with the synthetic resin, if the bending accuracy is not accurate, when the steel plate is mounted on the mold and the synthetic resin is molded by injection molding, etc. The thin part lacks stability, cracks,
Alternatively, there is a problem that the protruding part falls off, and if the above-mentioned bending accuracy is not accurate, the accuracy of the resin part covered there will also be a problem, resulting in a lack of smoothness during sliding. In addition, there is a problem that the steel plate that is the substrate rusts.

[Problems to be Solved by the Invention]

Therefore, in order to solve the above-mentioned problems, it is conceivable to integrally mold the entire carrier plate with synthetic resin. However, in this case, it is necessary to bring the synthetic resin close to the rigidity of the steel plate which is the substrate. In addition to the above, the entire product may warp due to the time lag of cooling during molding, and the protrusions may fall over. I have a problem.

An object of the present invention is to solve the problems when the above-mentioned carrier plate is molded with resin, and to provide a carrier plate which is equivalent in strength to the one using a steel plate as a conventional substrate.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, a resin carrier plate according to the present invention connects a wire holding portion, which is three-dimensionally formed by projecting on a flat plate-like substrate, and a slit guide or a slide guide with a shape-retaining rib. , The wire holding part,
It is characterized in that an oil holding chamber formed by a rib projectingly provided on the substrate is additionally provided, and on the back surface of the flat plate-shaped substrate, the outer peripheral edge or the outer peripheral edge and the outer peripheral edge of the substrate are formed. A rib is provided in the vicinity of the peripheral edge, the ribs are connected by a plurality of reinforcing ribs, and the reinforcing ribs are connected by ribs that intersect the respective reinforcing ribs, and the ribs intersect the reinforcing ribs or the reinforcing ribs. A part of the ribs is a reinforcing rib on the back surface side of the opening formed in the substrate.

[Operation] In the resin carrier plate according to the present invention, since the wire holding portion which is three-dimensionally formed by projecting on the flat plate-shaped substrate and the slit guide or the slide guide are connected by the shape retaining rib, the projecting shape is formed at the time of molding. In the three-dimensionally formed wire holding portion and individual slit guides or slide guides, the cooling time differs between the outside and the inside during the cooling process, so that the wire formed in the protruding shape in three dimensions Although the holding portion, the slit guide or the slide guide tends to fall inward, the shape retaining rib is configured to be cooled and individualized before the wire holding portion, the slit guide or the slide guide which is the projecting body. Therefore, the above-mentioned protruding body is supported by the above-mentioned shape-retaining rib and does not fall down, so that a highly accurate slit guide or slide guide can be obtained and Will also be accurate. Further, since the oil holding chamber formed by the rib projectingly provided on the substrate is provided side by side with the above-mentioned wire holding portion, the oil filled in the holding chamber can smoothly move the carrier plate up and down.

Further, when the opening is formed in the substrate, the strength of the substrate is lowered, and since the inside of the opening has a core structure, cooling of the opening is delayed in the cooling step, and as a result, warpage occurs, In the present invention, a rib is provided on the outer peripheral edge of the back surface of the substrate, the ribs are connected by a plurality of reinforcing ribs, and a rib intersecting with the plurality of ribs is further provided. Even if a large opening is provided, the strength of the substrate can be obtained with the ribs.

The carrier plate A is smoothly moved along the guide rail 2.

A wire end mounting opening 25 is opened in the substrate 1 at a lower portion of the wire holding portion 10, and the wire holding portion 10 has a downwardly extending portion 27 on the opening 25 side via a groove portion 26. The wire end mounting portion 30 is formed by the recessed groove portion 28 formed on the back surface of the wire holding portion 10 and the recessed groove portion 29 formed on the back surface of the vertically extending portion 27.

Further, 31 and 31 are glass mounting holes formed at both ends in the longitudinal direction of the carrier plate A, and 32 and 32 'are peripheral portions of the substrate 1 from the above-mentioned upper slide guide 4 and lower slide guide 4'. A horizontal glass holding portion 40 is formed on the upper portion of the back surface of the carrier plate A by the rail guide reinforcing ribs provided upright on the glass plate, and both ends of the glass holding portion 40 reach the back surface of the glass mounting holes 31, 31. Reinforcing ribs 41, 41 are provided on the upper outer edge portion, and further, reinforcing ribs 42 are formed on the lower outer edge portion extending from one of the glass mounting holes 31, 31 to the other. Therefore, the upper and lower outer edge portions of the carrier plate A are surrounded by the reinforcing ribs 41 and 42, and the plurality of flange reinforcing ribs 43 are provided between the rib 41 of the upper outer edge portion and the rib 42 of the lower outer edge portion. , 43,43 …… are connected,
Also, in the back surface of the wire end mounting opening 25,

Has been done. In addition, the aforementioned flange reinforcing ribs 43, 43,
Ribs 46, 46, 46, ... That connect the 43 ,.

When the carrier plate is manufactured by integral molding of synthetic resin, the carrier plate A includes upper and lower slit guides 3 and 3 ', slide guides 4 and 4', and wire holding portions formed to project from the substrate 1. 10 is the above-mentioned upper and lower slit guides 3, 3'in the cooling step during molding.
Since the inner part of each of the slide guides 4 and 4'has a core structure, cooling lags behind the outer part in the cooling process during molding, and as a result, the upper and lower slide guides 4, 4 '
4'and the lower slit guides 3,3 'are in a state of inclining inward, but in the present embodiment, the upper slide guide 4 and the lower slide guide 4'have at least the height of the slide guides 4,3. Since the ribs 9 are connected to each other by a rib 9 having a width which is 1/2 or more of 4'and thinner than the thickness of the substrate 1, the ribs 9 solidify faster than the substrate 1 and the slide guides 4, 4 ', and the rigidity of the ribs 9 is increased. This prevents the slide guides 4 and 4 ′ from falling inward. Further, in the above-mentioned slit guides 3 and 3 ', the lower slit guide 3'is connected to the wire holding portion 10, and the height of the wire holding portion 10 and the upper slit guide 3 is different. Since ribs 11 having a width that is 1/2 or more of the slit guide 3 and is thinner than the thickness of the substrate 1 are connected, the ribs 11 solidify faster than the substrate 1 and the slit guides 3 in the cooling process, and thus collapse due to the rigidity of the ribs 11. Can be avoided.

Further, since the slit guides 3 and 3'are slidably engaged with the rail portion of the guide rail 2 fixed to the door side, when a large load from a window glass (not shown) is received, The sliding contact engaging portion of the present invention may be bent, and this bending may increase the displacement of the window glass, and sometimes the carrier plate A may be disengaged from the guide rail 2. However, in the present embodiment, Since the carrier plate A is provided with ribs connecting the upper and lower slit guides 3, 3 ', the strength of the slit guides 3, 3'can be improved, and the ribs 11 and ribs described above can be improved. 9 also has the effect of reinforcing the substrate 1.

Further, when the carrier plate A is normally moved up and down, a relatively small stress such as sliding resistance and the weight of the glass window is applied to the wire end housing attachment portion 30 in the working direction of the wire. Then, when the carrier plate A is located at the upper and lower limits and a force is further applied in the blocking direction of the glass, excessive stress is generated in the wire end storage mounting portion 30,
Destruction is also possible in some cases. Then, particularly in a high temperature atmosphere (about 80 ° C.), if excessive stress is applied to the wire end storage attachment portion 30 for a long time, there is a possibility that the original state may not be restored even if the temperature is returned to room temperature. However, in this embodiment, as described above, since the ribs 11 that connect the wire holding portion 10 in which the wire end housing attachment portion 30 is formed and the slit guide 3 are provided, the strength of the wire end in the wire working direction is increased. Not only can it be improved, but also the fall state of both can be prevented as described above.

The ribs 9 that connect the upper and lower slide guides 4 and 4'and the ribs 11 that connect the wire holding portion 10 and the upper slit guide 3 to the ribs 14 and 1 that slidably contact the guide rail 2 described above.
Since 4 ', 15, 15' are projected, the slide guide
4,4 ', effective for preventing lateral deformation of the slit guide 3, and further filling oil between the ribs 14,14', 15,15 'and the guide rail 2 described above. Due to
It is possible to smoothly move the carrier plate A up and down, and in the carrier plate A, the engaging portions with the guide rails 2 are only the slit guides 3, 3'and the slide guide portions 4, 4 '. A load from the glass side of the glass holder is applied to this engaging part, and a force from the handle side is applied to the wire end storage mounting part 30 as a wire tension. Further, the load direction is various with respect to the glass, the thickness direction, and the rotation direction, and as a result, the carrier plate which is the base of the wire guide 10 having the slit guides 3 and 3'and the wire end accommodating and mounting section 30. A force such as bending, pulling, and twisting is applied to the substrate 1 of A, and the substrate 1 is deformed in some cases, which is not preferable in practical use. Therefore, in the present embodiment, the outer edge portion is surrounded by the ribs 41 and 42 on the back surface of the carrier plate A, and the rib 4 of the outer edge portion is provided behind the opening 25 of the wire holding portion 10.
Opening reinforcement rib 44 and stopper reinforcement rib 45 connected to 1,42
Ribs 46, 4 orthogonal to the reinforcing ribs 44, 45 described above.
Since 6, are provided, the rigidity of the substrate 1 can be improved, and the stress generated at the wire end housing mounting portion 30 can be reduced. Since many protrusions such as the slit guides 3 and 3 ', the slide guides 4 and 4', and the wire holding portion 10 are provided on the surface of the carrier plate A, the cooling of the surface is delayed from the back surface in the cooling process. As a result,
Although the warp of the substrate 1 occurs, in the present embodiment, the back surface of the carrier plate A is surrounded by the reinforcing ribs 41 at the upper outer edge portion and the reinforcing ribs 42 at the lower outer edge portion to form a box-shaped structure. Further, the width is thinner than that of the substrate 1 by connecting with the reinforcing ribs on the outer edge portion, and the height is the outer edge ribs 41, 4 described above.
Since 1/2 or more of the flange reinforcing ribs 43, 43, ... Are provided, the box-shaped inner flange reinforcing ribs 43, 43, .. 43,43, ... are used to reduce the warp of the board.

Further, the board 1 of the carrier plate A has openings for attaching the wire ends and for holding the guide rail, and the existence of the openings impairs the strength of the board 1. Particularly, in the wire end mounting opening 25, since the wire end housing mounting portion 30 is disposed on one side thereof, when stress is applied to the opening 25, deformation in the opening direction becomes free. Therefore, the deformation of the wire end storage attachment portion 30 becomes large, and in some cases, the wire may come off. However, in the present embodiment, the opening reinforcing ribs 44, 44 'and the stopper reinforcing ribs 45 are provided on the back surface of the carrier plate A along each side of the opening, so that the strength of the opening 25 is increased. Further, when the above-mentioned opening 25 is provided, the inside of the opening has a core structure, so that the cooling of the opening is delayed in the cooling step, and as a result, warpage occurs, As described above, the opening reinforcing ribs 44, 44 'are provided, and the ribs are solidified before the substrate 1 to prevent warpage.

Further, when the handle is further strongly rotated in the closing direction with the window glass fully closed, an excessive force is applied to the wire end storage mounting portion 30, and the entire carrier plate A moves upward with the glass mounting holes 31 and 31 as fulcrums. In this embodiment, the horizontal ribs 40 provided on the upper edge portion are matched with the shape of the lower edge portion of the window glass, so that the carrier plate A is deformed upward. However, the rib 40 is in contact with the lower edge of the window glass and is not deformed any more. The rib 40 is effective for reinforcing the substrate 1 and preventing warpage during the cooling process.

A second embodiment of the present invention will be described with reference to FIGS. 11 and 12. In the second embodiment, the same or equivalent parts as those in the first embodiment will be described using the same reference numerals, and the operation and effect thereof are also substantially the same, but in the first embodiment described above,
As described above, the slide guide 4 and the slit guide 3
Although the slide guide 4'and the slit guide 3'are integrally formed, in the second embodiment, the slit guide 4 '
3, 3'and the slide guides 4, 4'are vertically shifted and arranged. To explain this in more detail, the upper slit guide 3 and the lower slit guide 3'are arranged vertically in the central portion of the guide rail 2. Grooves 5 and 5'to which the guides slide are provided, and an upper slide guide 4 and a lower slide guide 4'are arranged between the upper and lower slit guides 3 and 3 '. By forming the sliding surfaces 4a, 4a 'in contact with the outer surface of the vertical guide of the guide rail 2 on the supporting legs of the slide guides 4, 4', the carrier plate A can be slid smoothly. There is. Further, the wire holding portion 10 is connected to the lower slit guide 3'in the first embodiment, but in the second embodiment, the wire holding portion 10 is connected to the slit guide 3 '.
It is located farther away. Therefore, the upper slit guide 3 and the wire holding portion 10 are used as the fall prevention ribs.
There are provided a rib 11 for connecting between the wire holding portion 10 and the lower slit guide 3 '.

As described above, the slide guide 4 and the slit guide 3
In the case of integrally forming and, there is a problem in the structure of the injection molding die and it is necessary to use a large molding machine, but the carrier plate A becomes large and the upper and lower slit guides 3,
If the distance of 3'is long, the slide guide 4'is separated from the slit guide 3 ', and the slide guide 4'is arranged inside the slit guide 3', so that the mold is split. Therefore, it is possible to eliminate rattling when the window glass is moved up and down.
