JP 2006-044475 A

  However, the above-described vehicle wiper has a problem that the rigidity of the connecting shaft is lower than that of, for example, a metal connecting shaft, and the connecting strength between the wiper arm and the wiper blade cannot be secured. That is, in the above-described vehicle wiper, for example, when an impact is applied to the wiper blade when the so-called lockback of the vehicle wiper is released, the connecting shaft may be broken and the wiper blade may be detached from the wiper arm. .

  In contrast, there is a resin lever with a metal connecting shaft that is insert molded to ensure the rigidity of the connecting shaft, but this configuration increases the manufacturing cost due to the complexity of the insert molding process. End up.

  Although it is conceivable to simply secure the rigidity by thickening the connecting shaft integrally formed with the resin lever, when the connecting shaft is thickened, the dimension of the U-shaped mounting portion (U hook type) of the wiper arm becomes JIS D5710. And the compatibility with other wiper blades (for example, a cold region wiper blade) is lost.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a vehicle wiper that can ensure the rigidity of the connecting shaft at a low cost.

In the first aspect of the present invention, an opening is formed in the upper part of the resin lever constituting a part of the wiper blade, and the connecting member can be rotated on the connecting shaft disposed between the both side walls in the opening. A vehicular wiper that is supported and mounted with a substantially U-shaped U-shaped mounting portion formed at the tip of a wiper arm on the connecting member, and a pair of plate-shaped abutting abutting the both side walls inside the side walls A metal connection holder including a holder wall portion and the connection shaft that connects the pair of holder wall portions is mounted and fixed to the resin lever so that the connection shaft is disposed . A protrusion projecting inward is formed on at least one of the both side walls of the lever, and the protrusion is fitted to the holder wall portion of the connection holder so that the protrusion can be attached to the resin lever. A hole is formed, and the protrusion is It is set so as to protrude through the hole, and the connecting member has a pair of side walls facing the holder wall inside the holder wall, and the side wall includes A restricting portion that restricts a rotation range around the connecting shaft by engaging with the protrusion is provided .

  According to this configuration, since the connecting shaft is made of metal, it is not made thick, that is, without increasing the size of the U-shaped mounting portion (without deviating from that defined in JIS D5710). The rigidity of the connecting shaft can be ensured while using the resin lever, and the connecting strength between the wiper arm and the wiper blade can be ensured. In addition, a metal connection holder having a pair of plate-like holder wall portions that are in contact with both side walls inside the both side walls and a connection shaft that connects the pair of holder wall portions is mounted on a resin lever. Since the connecting shaft is disposed by fixing, complicated insert molding can be avoided and the cost can be reduced as compared with the case where the metal connecting shaft is insert-molded on the resin lever.

  According to this configuration, the connection holder is attached to the resin lever by the projection protruding inward from at least one of the both side walls of the resin lever fitting into the attachment hole formed in the holder wall portion of the connection holder. The Further, the protrusion protrudes inward through the mounting hole and engages with a restricting portion provided on the side wall portion of the connecting member, thereby limiting the rotation range around the connecting shaft of the connecting member. As a result, the relative rotation range of the wiper blade relative to the wiper arm (connection member) is limited to a predetermined angle with a simple structure using the protrusion for attaching the connection holder to the resin lever (the function is shared by the protrusion). can do. That is, the free rotation of the wiper blade when the wiper arm is locked back can be restricted. For example, it is possible to prevent the blade rubber of the wiper blade from facing the opposite side of the wiping surface.

In the second aspect of the present invention, an opening is formed in the upper portion of the resin lever that constitutes a part of the wiper blade, and the connecting member can be rotated on the connecting shaft disposed between both side walls in the opening. A vehicular wiper that is supported and mounted with a substantially U-shaped U-shaped mounting portion formed at the tip of a wiper arm on the connecting member, and a pair of plate-shaped abutting abutting the both side walls inside the side walls A metal connection holder including a holder wall portion and the connection shaft that connects the pair of holder wall portions is mounted and fixed to the resin lever so that the connection shaft is disposed . A protrusion projecting inward is formed on at least one of the both side walls of the lever, and the protrusion is fitted to the holder wall portion of the connection holder so that the protrusion can be attached to the resin lever. With holes or mounting recesses A convex portion that protrudes inward with the formation of the mounting hole or the mounting concave portion is formed, and the connecting member has a pair of side wall portions facing the holder wall portion inside the holder wall portion. The side wall portion is provided with a restricting portion that restricts a rotation range around the connecting shaft by engaging with the convex portion.

According to this configuration, since the connecting shaft is made of metal, it is not made thick, that is, without increasing the size of the U-shaped mounting portion (without deviating from that defined in JIS D5710). The rigidity of the connecting shaft can be ensured while using the resin lever, and the connecting strength between the wiper arm and the wiper blade can be ensured. In addition, a metal connection holder having a pair of plate-like holder wall portions that are in contact with both side walls inside the both side walls and a connection shaft that connects the pair of holder wall portions is mounted on a resin lever. Since the connecting shaft is disposed by fixing, complicated insert molding can be avoided and the cost can be reduced as compared with the case where the metal connecting shaft is insert-molded on the resin lever.
Further, the projection that protrudes inward from at least one of the both side walls of the resin lever fits into the mounting hole or the mounting recess formed in the holder wall portion of the connection holder, so that the connection holder is mounted to the resin lever. . Further, the convex portion protruding inward with the molding of the mounting hole or the mounting concave portion engages with the limiting portion provided on the side wall portion of the connecting member, thereby limiting the rotation range around the connecting shaft of the connecting member. It will be. Thus, the rotation of the wiper blade relative to the wiper arm (connection member) can be achieved with a simple configuration using a projection that protrudes inward with the molding of the mounting hole or mounting recess for mounting the connection holder on the resin lever. The range can be limited to a predetermined angle. That is, the free rotation of the wiper blade when the wiper arm is locked back can be restricted. For example, it is possible to prevent the blade rubber of the wiper blade from facing the opposite side of the wiping surface.

  According to a fourth aspect of the present invention, in the vehicle wiper according to any one of the first to third aspects, the connection holder connects the pair of holder wall portions at both longitudinal ends of the wiper blade. It has a connecting wall.

  According to this configuration, since the pair of holder wall portions are connected by the connecting walls at both longitudinal ends of the wiper blade, the connecting holder becomes a channel shape and its rigidity is increased. Becomes difficult to bend. Therefore, for example, the mounting strength in a state where the holder wall portions of the connection holder are mounted on both side walls of the resin lever can be increased, and rattling and dropping of the connection holder can be reduced.

According to a third aspect of the present invention, in the vehicle wiper according to the first or second aspect , the side wall portion of the coupling member can be inserted and supported so that the coupling shaft can be inserted and rotated in a direction orthogonal to the axis. The restricting portion of the connecting member is a restricting groove that engages with the protrusion or the convex portion at the end thereof and guides the protrusion or the convex portion within the range up to the end. The restriction groove is opened in the same direction as the insertion support portion.

  According to the same configuration, the insertion support portion that can be inserted from the direction orthogonal to the axis and can be rotatably supported, and engages with the protrusion or protrusion at the end thereof, and the protrusion or protrusion within the range up to the end. Since the limiting groove to be guided opens in the same direction, the connecting member can be easily assembled by relatively moving the connecting member in the opening direction with respect to the connecting shaft and the protrusion or the convex portion. That is, if the opening direction of the insertion support part and the restriction groove is different, the connecting shaft and the projection or the convex part cannot be arranged at the same time in the insertion support part and the restriction groove, so that the assembly becomes difficult or complicated. However, this can be avoided, and as a result, the connecting member can be easily assembled.

  ADVANTAGE OF THE INVENTION According to this invention, the wiper for vehicles which can ensure the rigidity of a connection shaft at low cost can be provided.

Hereinafter, an embodiment embodying the present invention will be described with reference to FIGS.
FIG. 1 shows a vehicle wiper 11 that wipes raindrops and the like adhering to a wiping surface 1a of a windshield (windshield glass) 1 of an automobile. The vehicle wiper 11 includes a wiper arm 12, a wiper blade 13, and a connecting clip 14 as a connecting member. The wiper arm 12 is fixed to a pivot shaft (not shown) whose base end is reciprocated at a predetermined angle by a driving force of a wiper motor (not shown), and reciprocally swings as the pivot shaft reciprocates. Do exercise. A substantially U-shaped (U hook type) U-shaped attachment portion 12 a (see FIG. 5) is formed at the tip of the wiper arm 12. Then, a connecting clip 14 is rotatably provided at a longitudinal intermediate portion of the wiper blade 13, and the wiper arm 12 and the connecting clip are mounted by attaching the U-shaped attachment portion 12a to the connecting clip 14 as will be described later. A wiper blade 13 is rotatably connected to 14. The wiper arm 12 is provided with a spring (not shown) for applying a pressing force for pressing the wiper blade 13 against the wiping surface 1a.

As shown in FIG. 2, the wiper blade 13 of the present embodiment includes a lever member 21, a blade rubber 22, and two resin movable cover members 23.
The lever member 21 is rotatably connected to the U-shaped attachment portion 12a of the wiper arm 12 at a longitudinal intermediate portion of a main lever 24 as a resin lever, and is made of resin at both longitudinal ends of the main lever 24. The yoke lever 25 is formed in a tournament shape by connecting the intermediate portions in the longitudinal direction of the yoke lever 25 so as to be rotatable about the rotation axis X1.

  A grip portion 25a is formed at both longitudinal ends of the yoke lever 25, and the upper portion of the blade rubber 22 is gripped by the grip portion 25a. A backing is attached to the upper portion of the blade rubber 22. This backing disperses the pressing force applied to the wiping surface 1a received from the wiper arm 12 in the longitudinal direction, and follows the end portion of the blade rubber 22 projecting in the longitudinal direction from the grip portion 25a located at the end of all the grip portions 25a. Also in 22a, the wiping surface 1a is pressed.

  Further, a base end portion of the movable cover member 23 is rotatably connected to a position (rotation axis X2) of the yoke lever 25 protruding from the main lever 24 in the longitudinal direction. A holding portion 23 a is formed at the tip of the movable cover member 23, and the upper portion of the tip of the follow-up end 22 a of the blade rubber 22 is held by the holding portion 23 a. Further, the movable cover member 23 substantially covers the yoke lever 25 together with the main lever 24 and constitutes the appearance of the wiper blade 13. Further, on the front side of the vehicle at the main lever 24 and the movable cover member 23 (the front side in the attached state), a force for pressing the blade rubber 22 toward the wiping surface 1a is generated when receiving the traveling wind during traveling of the vehicle. A fin surface 31 (see FIG. 2A) is formed. The fin surfaces 31 formed on the main lever 24 and the movable cover member 23 are formed so as to have a continuous appearance over the entire longitudinal direction of the wiper blade 13 in cooperation with each other.

Here, the connection structure of the wiper arm 12, the wiper blade 13, and the connection clip 14 will be described in detail.
First, the main lever 24 is formed in a generally U-shaped cross section in the longitudinal direction (opened on the wiping surface 1a side) as a whole, and at the upper portion of the middle portion in the longitudinal direction (the portion on the side away from the wiping surface 1a). Are formed with an upper opening 24a (see FIGS. 2A and 3A) as an opening penetrating in the vertical direction (perpendicular to the wiping surface 1a). Further, in the main lever 24, a longitudinal direction (FIG. 3 (a) that protrudes inward (towards each other) at the lower end (end on the wiping surface 1a side) of the side walls 24b at a position corresponding to the upper opening 24a. ), A pair of locking pieces 24c are formed in the horizontal direction). Further, in the both side walls 24b, the center in the vertical direction (the direction perpendicular to the wiping surface 1a and the vertical direction in FIG. 3A) and one from the center in the longitudinal direction (right in FIG. 3A). ), A locking projection 24d (see FIG. 3B) is formed as a projection protruding inward. As shown in FIG. 3B, the lower surface of the locking projection 24d (the surface on the side facing the wiping surface 1a on the side surface of the projection) is upward (away from the wiping surface 1a) toward the tip. The inclined surface 24e is directed in the direction of

A metal connection holder 41 is mounted and fixed at a position corresponding to the upper opening 24 a of the main lever 24.
As shown in FIGS. 3 and 4, the connection holder 41 includes a pair of plate-like holder wall portions 41 a that are in contact with the side walls 24 b inside the side walls 24 b of the main lever 24, and the pair of holder wall portions. A connecting shaft 41b for connecting 41a at the approximate center, and a connecting wall 41e for connecting the pair of holder wall portions 41a at both ends in the longitudinal direction (of the wiper blade 13) (both ends in the left-right direction in FIG. 3A). Prepare. The holder wall portion 41a is formed slightly longer than the longitudinal length of the upper opening 24a (the length in the left-right direction in FIG. 3A). An inscribed portion 41d that is inscribed is formed. And in the upper part of a pair of holder wall part 41a, the lower surface (wiping surface 1a side) of the longitudinal direction both ends in the upper opening 24a is on the outer side of the inscribed part 41d (the outer side in the left-right direction in FIG. 3A). The connection wall 41e is formed to connect the pair of holder wall portions 41a so as to be in surface contact with each other. The vertical length of the holder wall 41a is such that the connecting wall 41e is in contact with the lower surfaces of both ends in the longitudinal direction of the upper opening 24a (see FIG. 3A), and the lower end is the locking piece. 24c is set so as to be in contact with and supported in the vertical direction. Further, a mounting hole 41f into which the locking projection 24d is fitted is formed at a position corresponding to the locking projection 24d of the holder wall portion 41a. Here, as shown in FIG. 3 (b), the amount of protrusion of the locking protrusion 24d is set so as to pass through the mounting hole 41f and protrude further inward while being fitted in the mounting hole 41f. . And as above-mentioned, each part contact | connects the main lever 24, and the connection holder 41 fits the latching protrusion 24d in the mounting hole 41f, and the lower end of the holder wall part 41a is supported by a pair of latching piece 24c. Is attached and fixed to the main lever 24.

As shown in FIGS. 5 and 6, the connection clip 14 includes a pair of side wall portions 14 a, a side wall connection portion 14 b, and a clamping lock portion 14 c.
The pair of side wall portions 14a is formed in a plate shape facing the holder wall portion 41a inside the holder wall portion 41a, and a part of the side wall portion 14a can be inserted and supported so that the connecting shaft 41b can be inserted from the direction orthogonal to the axis. The support portion 14d (see FIG. 6B) is formed so as to be cut out. As shown in FIG. 6B, the insertion support portion 14d opens downward (in the direction of the wiping surface 1a), and the width of the opening is slightly smaller than the diameter of the connecting shaft 41b. The end portion on the opposite side of the surface 1a) is formed in an arc shape along the outer periphery of the connecting shaft 41b. Thus, the insertion support portion 14d can insert the connecting shaft 41b (while slightly bending), and can support (hold) the inserted connecting shaft 41b so as to be rotatable.

  Further, the side wall portion 14a is a limiting portion for limiting the rotation range around the connecting shaft 41b of itself (the connecting clip 14) by engaging with the locking protrusion 24d (see FIGS. 3 and 5). The limiting groove 14e is formed. The limiting groove 14e is formed to engage with the locking protrusion 24d at the end thereof and to be able to guide the locking protrusion 24d within the range up to the end, and is in the same direction as the insertion support portion 14d (downward direction, wiping surface). 1a direction).

  The side wall connecting portion 14b is formed to connect the pair of side wall portions 14a on the opposite side of the limiting groove 14e with the insertion support portion 14d (connection shaft 41b) as the center, and a part of the side wall connection portion 14b is part of the insertion support portion 14d. A cylindrical portion 14f having an arcuate cross section having an inner surface having the same shape as the arc shape of the insertion support portion 14d is formed so as to support the connecting shaft 41b together with the back portion (arc-shaped portion).

  Further, as shown in FIG. 5, the clamping lock portion 14c is disposed so as to face the cylindrical portion 14f, and is provided so as to be able to clamp the arc portion 12b of the U-shaped attachment portion 12a together with the cylindrical portion 14f. Specifically, as shown in FIGS. 5 and 6B, the clamping lock portion 14c is rotatably supported by a support shaft 14g formed on the pair of side wall portions 14a on the opposite side of the cylindrical portion 14f. By rotating, the tip of the clamping lock portion 14c is provided so as to face the cylindrical portion 14f. In addition, the front-end | tip part of this holding | maintenance lock part 14c is made into the shape which gives elasticity easily to bend by being made thin partially.

  As shown in FIG. 5, the connecting clip 14 has the cylindrical portion 14f on the arcuate portion 12b of the U-shaped mounting portion 12a in a state where the connecting shaft 41b is supported by the insertion support portion 14d and the cylindrical portion 14f. And the wiper arm 12 is mounted so that the side wall connecting portion 14b is interposed (clamped) between the parallel portions 12c of the U-shaped attachment portion 12a. Then, in this state, the holding lock portion 14c is rotated so that the tip end portion holds the arc portion 12b together with the cylindrical portion 14f, thereby preventing the U-shaped attachment portion 12a from coming off from the connecting clip 14. . Accordingly, the wiper blade 13 is rotatably connected to the wiper arm 12 and the connection clip 14.

Next, characteristic effects of the above embodiment will be described below.
(1) Since the connecting shaft 41b is made of metal, the resin does not increase in thickness, that is, without increasing the size of the U-shaped attachment portion 12a (without deviating from that defined in JIS D5710). The rigidity of the connecting shaft 41b can be ensured while using the main lever 24 made of the product, and the connecting strength between the wiper arm 12 and the wiper blade 13 can be ensured. Further, a metal plate provided with a pair of plate-like holder wall portions 41a that abut against the both side walls 24b inside the both side walls 24b of the main lever 24 and a connecting shaft 41b that connects the pair of holder wall portions 41a. Since the connecting shaft 41b is disposed by attaching and fixing the connecting holder 41 to the resin main lever 24, the insert is more complicated than the case where the metal connecting shaft is insert-molded into the resin main lever 24. Molding can be avoided and cost reduction can be achieved.

  (2) The engagement protrusions 24d protruding inwardly from the both side walls 24b of the main lever 24 are fitted into the mounting holes 41f formed in the holder wall portion 41a of the connection holder 41, so that the connection holder 41 is connected to the main lever 24. Installed. Further, the locking protrusion 24d protrudes inward through the mounting hole 41f, and engages with a limiting groove 14e formed in the side wall portion 14a of the connection clip 14, thereby rotating the connection clip 14 around the connection shaft 41b. Limit the range. Accordingly, the wiper blade 13 for the wiper arm 12 (the coupling clip 14) can be configured with a simple configuration using the locking projection 24d for mounting the connection holder 41 on the main lever 24 (the locking projection 24d has a common function). Can be limited to a predetermined angle. That is, the free rotation of the wiper blade 13 when the wiper arm 12 is locked back can be restricted. In the present embodiment, the blade rubber 22 of the wiper blade 13 faces the opposite side of the wiping surface 1a. Can be prevented.

  (3) Since the pair of holder wall portions 41a are connected by the connecting walls 41e at both longitudinal ends of the wiper blade 13, the connecting holder 41 becomes a channel shape and its rigidity is increased. The end becomes difficult to bend. Therefore, for example, the mounting strength in a state where the holder wall portion 41a of the connection holder 41 is mounted on the both side walls 24b of the main lever 24 can be increased, and rattling and dropping of the connection holder 41 can be reduced.

  (4) An insertion support portion 14d capable of rotatably supporting the connecting shaft 41b from the direction orthogonal to the axis, and engaging with the locking projection 24d at the end thereof and guiding the locking projection 24d up to the end thereof Since the restriction groove 14e to be opened opens in the same direction (downward and in the wiping surface 1a direction), the connecting clip 14 is moved relative to the connecting shaft 41b and the locking projection 24d in the opening direction. Thus, the connecting clip 14 can be easily assembled. That is, if the opening directions of the insertion support portion 14d and the restriction groove 14e are different, the connecting shaft 41b and the locking projection 24d cannot be simultaneously disposed in the insertion support portion 14d and the restriction groove 14e, and the assembly becomes difficult. However, this can be avoided, and as a result, the connecting clip 14 can be easily assembled.

The above embodiment may be modified as follows.
In the above embodiment, the locking projection 24d of the main lever 24 passes through the mounting hole 41f of the connection holder 41 and protrudes into the inside, and engages with the restriction groove 14e of the connection clip 14 so that the connection shaft of the connection clip 14 is engaged. Although the rotation range around 41b is limited, the rotation range of the connecting clip 14 may be limited by another configuration.

  For example, as shown in FIG. 7 (a), a protrusion 41h that protrudes inward with the formation (cutting up) of the mounting hole 41g into which the locking protrusion 24f of the main lever 24 fits is formed as a holder wall 41a of the connection holder 41. The convex portion 41h is engaged with the restriction groove 14e (see FIGS. 5 and 6) of the connection clip 14 so that the rotation range around the connection shaft 41b of the connection clip 14 is limited. Good.

  Even in this case, the wiper with respect to the wiper arm 12 (connection clip 14) can be formed with a simple configuration using the convex portion 41h protruding inward with the formation of the mounting hole 41g for mounting the connection holder 41 to the main lever 24. The relative rotation range of the blade 13 can be limited to a predetermined angle.

  Further, for example, as shown in FIG. 7B, a convex portion 41j that protrudes (inflates) inward with the formation of the mounting concave portion 41i into which the locking projection 24d of the main lever 24 fits is formed on the holder wall of the connection holder 41. The protrusion 41j is formed in the portion 41a, and the rotation range around the connecting shaft 41b of the connecting clip 14 is restricted by engaging the restricting groove 14e (see FIGS. 5 and 6) of the connecting clip 14. May be.

  Even in this case, the wiper with respect to the wiper arm 12 (the coupling clip 14) can be formed with a simple configuration using the convex portion 41j that protrudes inward as the mounting concave portion 41i for mounting the coupling holder 41 on the main lever 24 is formed. The relative rotation range of the blade 13 can be limited to a predetermined angle.

  Of course, as shown in FIG. 7C, a convex portion 41l is formed on the holder wall portion 41a at a position different from the mounting hole 41k into which the locking projection 24f of the main lever 24 is fitted. The rotation range around the connection shaft 41b of the connection clip 14 may be limited by engaging with the restriction groove 14e (see FIGS. 5 and 6) of the connection clip 14.

  In the above embodiment, the pair of holder wall portions 41a in the connection holder 41 are preferably connected by the connection walls 41e at both ends in the longitudinal direction of the wiper blade 13. However, the present invention is not limited to this. It is good also as a structure which is not connected by the connection wall 41e in a part (the connection wall 41e was deleted).

  In the above-described embodiment, as described above, the connection holder 41 is configured such that each part comes into contact with the main lever 24 and the locking projection 24d fits into the mounting hole 41f and the lower end of the holder wall part 41a is a pair of locking pieces 24c. It is assumed that the main lever 24 is mounted and fixed by being supported by the other, but may be mounted and fixed by other configurations.

  In the above embodiment, the lever member 21 is composed of the main lever 24 and the yoke lever 25. However, the present invention is not limited to this. For example, an intermediate lever is rotatably connected to the main lever. A yoke lever may be rotatably connected to the intermediate lever (a tournament having a multi-stage shape as compared with the above embodiment). Further, for example, the lever member may be configured so that only the main lever, that is, the blade rubber is directly held by the main lever. Of course, in these cases, the main lever is made of resin, and the connection holder 41 is mounted and fixed to the main lever as in the above embodiment. Of course, the wiper blade may not be provided with the movable cover member 23.
