Description

  The present invention relates to a wiper blade having a configuration in which a refill is attached to a lower surface side of a long vertebra part.

  Conventionally, for example, in order to wipe a wiping surface such as a window surface of a windshield of a vehicle, it is widely known to use a wiper having an elongated wiper trip that slides on the wiping surface. As such a wiper, a joint member provided at an intermediate position in the longitudinal direction of the wiper trip is pivotally attached to the wiper arm, and along the wiper trip so that two windshield strips that are subjected to rubbing flow caused by running wind sandwich the joint member. And a cover cap that covers the joint member so as to harmonize both windshield strips and the joint member is known (see, for example, Patent Document 1).

  In addition, as another wiper, a refill as a wiper trip is urged by a long plate-shaped vertebra so that the refill is uniformly brought into contact with the wiping surface, and a clip base as a joint member and a windshield strip as 2 There is a wiper blade in which two spoilers are provided on the vertebra and the clip base is covered with a clip base cover as a cover cap. In this wiper blade, the refill is attached to the lower surface of the vertebra (the surface facing the wiping surface), and the clip base is attached to the upper surface of the vertebra, and each spoiler is located on both side edges located in the width direction of the vertebra The clip base cover is configured to cover the ends facing the clip bases of both spoilers together with the clip base.

The clip base cover is open at the lower end, and accepts the ends of both spoilers at both end wall portions facing in the extending direction of the vertebra while positioning the clip base between both side wall portions facing in the width direction of the vertebra. As shown, the clip base is mounted from the lower end side. Thus, the wiper blade described above has a harmonious appearance from one spoiler through the clip base cover to the other spoiler when viewed in the extending direction, and the clip base and the wiper arm are pivotally attached. The place is protected.

  By the way, in the wiper blade described above, the width of the refill attached to the lower surface of the vertebra is smaller than the width of the vertebra so as to receive the urging force from the vertebra, but the spoiler covers both side edges and the upper surface of the vertebra. Therefore, the width dimension is larger than the width dimension of the vertebra. Since the clip base cover receives the end portions of both spoilers at both end wall portions, the interval between both side wall portions is formed larger than the width dimension of the spoiler.

  However, both side walls of the clip base cover are shaped so as not to be uneven when viewed in the extending direction of the vertebra so that the appearance can be harmonized with both spoilers, and the lower end of the clip base cover is open. If the distance between the side walls is set larger than the width of the spoiler, the lower end facing the wiping surface is opened between the refill attached to the lower surface of the vertebra and the side walls, and the clip base cover is opened from there. A lower open space that leads to the outside of the space is formed. For this reason, for example, when wiping the wiping surface, ice and snow enter the lower open space, and the ice and snow that has entered is held in the lower open space. Then, the held ice and snow sticks, and the new ice and snow adhere to the stuck ice and snow, and the new and attached ice and snow are integrated with the stuck ice and snow, and the stuck ice and snow may be enlarged. . This enlarged ice and snow prevents the refill from coming into contact with the wiping surface by sliding the lower open space from the outside on the wiping surface side and preventing the refill from sliding properly. This increases the weight of the wiper blade and prevents proper sliding movement.

  The present invention has been made in view of the above problems, and maintains an appearance that is harmonized with both spoilers when viewed in the extending direction of the vertebra, and between the both side walls of the clip base cover and the refill. It is an object of the present invention to provide a wiper blade capable of preventing ice and snow from entering a lower open space.

In order to solve the above-described problem, the wiper blade according to claim 1 includes a long refill for wiping the wiping surface, and a long vertebra attached to the lower surface facing the wiping surface, A clip base that is attached to the upper surface of the vertebra and is pivotally attached to a wiper arm at an intermediate position in the extending direction of the vertebra, and two spoilers that are attached to the vertebra so as to sandwich the clip base and cover the vertebra A clip base cover that covers the clip base while spanning both spoilers;
The clip base cover has a lower end opened to accept the clip base and two side wall portions facing in the width direction of the vertebra, and is attached to the clip base at both ends in the extending direction of the vertebra. The clip base is attached to the clip base from the lower end side so that the clip base is positioned between the both side wall portions while receiving the end portions of the spoilers facing each other. The spoiler extends along the both side walls in the extending direction of the vertebra so as to shield the open portion of the lower open space formed between the refill located between the both ends of the spoiler and the both side walls. shielding plate is provided, wherein the shielding plate is formed continuously with the lower end of the side wall portions of the clip base cover, the clip base mosquito Is attached to the clip base and then bent toward the vertebra, and the shielding plate is provided with an engagement hole, and the engagement hole is formed in the both side walls of the clip base cover. An engaging claw capable of engaging with the engaging plate is provided, and when the shielding plate is bent toward the vertebra, the engaging claw is engaged with the engaging hole, whereby the lower open space is It is fixed at a position for shielding the open positions, characterized in Rukoto.

  A wiper blade according to claim 2 is the wiper blade according to claim 1, wherein the shielding plate is made of a resin material.

  According to the present invention, the open portion of the lower open space formed between the both side walls of the clip base cover and the refill located between both ends of both spoilers is shielded by the shielding plate. It is possible to prevent ice and snow from entering the lower open space while maintaining an appearance that is harmonized with both spoilers when viewed in the extending direction. For this reason, it is possible to prevent the wiper blade from properly wiping the wiping surface due to the enlargement of the ice and snow held in the lower open space.

The two side wall portions 30 and 31 are formed so as to have different inclinations when viewed in the vertical direction, similarly to the spoiler 16. The side wall 30 is inclined to follow the outer surface 16 a of the spoiler 16, and the side wall 31 is inclined to follow the outer surface 16 b of the spoiler 16. Moreover, since the both-ends wall parts 32 and 33 are the structures which receive the one end part 16f of both spoilers 16 so that it may mention later, the space | interval of the both-side wall parts 30 and 31 is set larger than the width dimension of both spoilers 16. Yes.

  Further, a plurality of protruding strips 36 and a plurality of locking protrusions 37 are provided on each of the two side wall portions 30 and 31 (see FIGS. 6 and 7). The clip base cover 15 is attached to the clip base 14 from the lower end 15a side (see arrow A in FIG. 6), and when the clip base 14 is interposed between the side wall portions 30 and 31, the opposite wall portions 14a are connected to each other. The protrusions 36 are pressed and clamped, and the engaging protrusions 37 are engaged with the engaging holes 14 c of the clip base 14 and attached to the clip base 14.

  The two end wall portions 32 and 33 extend in the width direction of the vertebra 12 so as to face each other in the direction in which the vertebra 12 extends. The both end walls 32 and 33 have cutouts 32a and 33a (see FIG. 1) shaped to follow the outer surfaces 16a and 16b of the spoiler 16. The clip base cover 15 has the notches 32a and 33a so that both end walls 32 and 33 can receive one end 16f of both spoilers 16 (see FIG. 10).

  An upper wall opening 34a is formed at the center of the upper wall 34, and a wiper arm (not shown) is attached to a clip (not shown) provided on the rivet 20 of the clip base 14 through the upper wall opening 34a. (Not shown) can be attached.

  Here, in the wiper blade 10, as described above, the head 11 b of the refill 11 is inserted into the second space 19 having a smaller width than the first space 18 through which the vertebra 12 is inserted. 12, the width of the head 11b of the refill 11 is smaller than the width of the vertebra 12 (see FIG. 4B). Further, both spoilers 16 have outer surfaces 16a and 16b set in consideration of the air flow around them, and are configured to receive the vertebra 12 in the recesses 21, so that the width dimension of the vertebra 12 is larger. Is also a large width dimension (see FIG. 3B). Further, as described above, since the distance between the side wall portions 30 and 31 of the clip base cover 15 is set to be larger than the width dimension of both spoilers 16 (see FIG. 10), both end portions 16f of both spoilers 16 are used. A lower open space 35 (see FIG. 9) is formed between the refill 11 positioned between the two and the side wall portions 30 and 31 of the clip base cover 15. Since the lower open space 35 has the lower end 15a of the clip base cover 15 open, the lower open space 35 is on the side facing the lower wiping surface S, that is, between the lower ends 30a, 31a of the side walls 30, 31 and the refill 11. It communicates with the outside of the clip base cover 15 via a gap (open portion 35a).

  In the wiper blade 10 according to the present invention, a shielding plate 40 that shields the open portion 35 a of the lower open space 35 is provided in the vicinity of the lower end 15 a of the clip base cover 15.

  In this embodiment, the shielding plate 40 includes shielding plates 40a and 40b provided at the lower ends 30a and 31a of the side wall portions 30 and 31 of the clip base cover 15, as shown in FIGS.

Each engaging claw 41 protrudes from the side wall portion 30 and the side wall portion 31 and extends downward, and can be engaged with the engaging hole 43 at its extended end 41a.

  Next, a procedure for attaching the refill 11, the spoiler 16, and the clip base cover 15 to the vertebra 12 to which the clip base 14 and the holder 13 are fixed in advance will be described.

  The head portion 11 b constituting the upper end portion of the refill 11 is inserted through the second space 19 of the holder 13. At this time, the refill 11 can be attached to the vertebra 12 by sequentially inserting the holders 13 installed on the one end 12 b side of the vertebra 12.

  Next, the two spoilers 16 are attached to the upper surface 12d of the vertebra 12 to which the refill 11, each holder 13, and the clip base 14 are attached so as to sandwich the clip base 14 therebetween. Both spoilers 16 can be attached to the vertebra 12 by housing the vertebra 12 in the recess 21 (see FIG. 4).

  When the spoiler 16 is installed on the vertebra 12, the vertebra 12 and each holder 13 are accommodated in the recess 21 with the wiping portion 11 e of the refill 11 exposed from the recess opening 21 a of the recess 21 of the spoiler 16. The vertebra 12 and each holder 13 are covered with a spoiler 16.

  The clip base cover 15 is attached to the clip base 14. The clip base cover 15 is mounted from the upper surface 12d side of the vertebra 12 so as to receive the clip base 14 from the opened lower end 15a side (see arrow A in FIG. 6).

  In the clip base cover 15, the protruding strips 36 formed on the side wall portions 30 and 31 press the opposing wall portions 14a of the clip base 14 to sandwich the clip base 14, and the locking projection 37 is the clip base. It is attached to the clip base 14 by engaging with the 14 locking holes 14c. At this time, the outer surfaces 16a and 16b of the spoilers 16 are fitted into the notches 32a and 33a (see FIG. 1) of the both end walls 32 and 33 of the clip base cover 15 (see FIG. 10). One end of each spoiler 16 The part 16f is accommodated in the clip base cover 15 (see FIG. 4). As a result, in the wiper blade 10, the clip base cover 15 covers the end portions 16 f of both spoilers 16 and the clip base 14 so as to bridge the spoilers 16.

  In the wiper blade 10 of the present invention, the two shielding plates 40 of the clip base cover 15 are folded back toward the refill 12 from the above state (see arrow B in FIG. 8), and are engaged with the engagement holes 43 of the shielding plates 40. The pawl 41 is inserted and engaged (see FIG. 8). In the present embodiment, the recesses 42 (see FIG. 7) are formed between the shielding plates 40 and the side wall portions 30 and 31, so that the folding is easy.

  Thereby, the assembly | attachment of the wiper blade 10 of a present Example is complete | finished. The two shielding plates 40 of the wiper blade 10 are extended along the side wall portion 30 so that one shielding plate 40a covers between the side wall portion 30 and the refill 11 of the clip base cover 15, and the other shielding plate 40b. Is extended along the side wall 31 so as to cover the space between the side wall 31 of the clip base cover 15 and the refill 11. For this reason, the two shielding plates 40 (40a, 40b) are formed between the refill 11 located between both end portions 16f of both spoilers 16 and both side wall portions 30, 31 of the clip base cover 15. The open portion 35a of the lower open space 35 (see FIG. 9) is shielded.

  In the wiper blade 10, a clip (not shown) provided with a wiper arm (not shown) on the rivet 20 of the clip base 14 through the upper wall opening 34 a of the upper wall portion 34 of the clip base cover 15. Attached to.

  The wiper blade 10 is given a biasing force toward the wiping surface S by a wiper arm (not shown) attached to the clip 16 of the clip base 14. This urging force is evenly transmitted to the refill 11 by the elastic action of the vertebra 12. For this reason, the wiping part 11 e of the refill 11 is in contact with the wiping surface S with an equal pressing force. The wiper blade 10 can wipe the wiping surface S by the wiping portion 11e sliding on the wiping surface S as the wiper arm swings.

  In the wiper blade 10, the clip base cover 15 that spans both spoilers 16 covers the clip base 14 and one end 16 f of both spoilers 16, and the clip base cover 15 is removed from one spoiler 16 when viewed in the extending direction. Then, the other spoiler 16 has a uniform and harmonious appearance, and the pivot joint between the clip base 14 and the wiper arm (not shown) is protected.

  In the wiper blade 10, as shown in FIG. 9, a lower open space 35 is formed between the refill 11 positioned between both end portions 16 f of both spoilers 16 and both side wall portions 30 and 31 of the clip base cover 15. However, since the lower end 15a of the clip base cover 15 is provided with the shielding plate 40 (40a, 40b), it is possible to prevent foreign matter from entering the lower open space 35 from the outside. This is because the lower open space 35 is connected to the outside through the open portion 35a between the lower ends 30a, 30b of the side wall portions 30, 31 of the clip base cover 15 and the refill 11 on the wiping surface S side which is the lower side. However, since the shielding plate 40a covers between the lower end 30a of the side wall 30 and the refill 11, and the shielding plate 40b covers between the lower end 31a of the side wall 31 and the refill 11, both shielding is performed. The open portion 35 a is shielded by the plate 40. Therefore, the wiper blade 10 can prevent foreign matter from entering the lower open space 35 through the open portion 35a. For example, wiped ice and snow can enter the lower open space 35 even during snowfall. Can be prevented. As a result, icy snow enters the lower open space 35, and the icy snow is held and fixed in the lower open space 35, new icy snow adheres to the fixed icy snow, and the new icy snow adhering is integrated with the fixed icy snow. It is possible to prevent the fixed ice and snow from being enlarged. For this reason, due to the enlarged snow and snow, the refill 11 is prevented from sliding properly contacting the wiping surface S, or the proper sliding movement of the swinging wiper blade 10 is inhibited. Never do.

  In the wiper blade 10, before the clip base cover 15 is attached to the clip base 14, both shielding plates 40 (40 a, 40 b) are directed downward from the lower ends 30 a, 30 b of the side wall portions 30, 31 of the clip base cover 15. Both side walls 30 in the extending direction of the vertebra 12 so as to shield the open portion 35a of the lower open space 35 by being folded after the clip base cover 15 is attached to the clip base 14, The clip base cover 15 can be easily attached to the clip base 14 and the shielding plate 40 can be easily provided.

  Furthermore, in the present embodiment, since the shielding plate 40 is formed of a resin material, even if ice and snow adhere to the shielding plate 40, the attached ice and snow easily peels from the shielding plate 40. When the wiper blade 10 is swung so as to slide on the wiping surface S, ice and snow can be dropped from the shielding plate 40. For this reason, even if ice and snow adhere to the shielding plate 40, the ice and snow will not be enlarged and the function of the wiper blade 10 will not be deteriorated.

  Therefore, in the wiper blade 10 of the present embodiment, the both side walls 30 and 31 of the clip base cover 15 and the clip base 14 are maintained while maintaining an appearance that is harmonized with both spoilers 16 when viewed in the extending direction of the vertebra 12. It is possible to prevent ice and snow from entering the lower open space 35 between the two.

  In the above-described embodiment, the shielding plate 40 is formed so as to be constant with the both side walls 30 and 31 of the clip base cover 15, but may be configured separately from the both side walls 30 and 31. Good. In this case, as shown in FIG. 11, only the engaging claws 410 are provided on the both side walls 300 and 310 of the clip base cover 150, and the two shielding plates 400 are formed separately from the both side walls 300 and 310. To do. Similar to the two shielding plates 40a and 40b, the two shielding plates 400 (400a and 400b) are provided with engagement holes 430 at positions corresponding to the engagement claws 410, and both side walls are viewed in the extending direction of the vertebra 120. The shield plate 400a covers the space between the lower end 300a of the side wall portion 300 and the refill 110, and the shield plate 400b extends between the bottom end 310a of the side wall portion 310 and the refill 110. What is necessary is just to form in the width dimension which can be covered. Even in this case, the shielding plate 400 can be installed in the vicinity of the lower end 150 a of the clip base cover 150 after the clip base cover 150 is attached to the clip base 140. Furthermore, in the clip base cover 150, since the shielding plate 400 does not exist below the lower ends 300a and 310a of the side wall portions 300 and 310 before being attached to the clip base 140, the clip base cover 150 is more than the clip base cover 15 of the above-described embodiment. It can be easily attached to the clip base 140.

  The wiper blade according to the present invention has been described with reference to the drawings. However, the wiper blade according to the present invention is not limited to the above, and a shielding plate is provided in the vicinity of the lower end of the clip base cover. If it is,

  Further, the shielding plate is formed between the refill 11 located between both end portions 16 f of both spoilers 16 and both side wall portions 30 and 31 of the clip base cover 15 in the vicinity of the lower end 15 a of the clip base cover 15.
