Description

  The present invention relates to a wiper connection structure, and more particularly, to an improved structure for connecting a wiper blade and a wiper arm by a holder base and a clip.

  Conventionally, a wiper is attached to a vehicle in order to wipe off raindrops, snow, and the like attached to a windshield (glass). For example, as shown in the side view of FIG. 8 (a), the wiper includes a wiper arm 10 'fixed to the vehicle, and a wiper blade 50 that is connected to the wiper arm 10' and swivels while contacting the windshield. The wiper blade 50 'is equipped with a wiper rubber.

  Here, since the wiper blade 50 'needs to be replaced due to a decrease in wiping performance such as aging deterioration, the wiper blade 50' can be engaged with and disengaged from the wiper arm 10 '.

  That is, for example, as shown in the detailed view of FIG. 8B, the wiper blade 50 'is provided with a support shaft 70 formed of a metal rivet, and the wiper arm is engaged with the support shaft 70. A hole 16 'is formed at the end of 10'.

  In addition, the cross section of the support shaft 70 is not a perfect circle, but the hole 16 'of the wiper arm 10' and the support shaft 70 are formed in a D shape with a part of the circumferential wall cut off. This is because the wiper blade 50 'is prevented from falling off in the actual use state of the wiper.

The wiper blade 50 'is made of metal, but the hatched portion in FIG. 8 (b) is formed as a metal holder separate from the wiper blade 50' and joined to the wiper blade 50 '. In some cases (Patent Document 1).
JP 2000-355270 A

  However, the conventional wiper coupling structure described above has a support shaft in which the side surface of the end of the wiper arm 10 'is inscribed in the both side walls of the wiper blade 50' as shown in the plan view of FIG. Although the displacement in the width direction at the engaging portion with 70 is restricted to some extent, the restriction is effective only for a single point in the longitudinal direction indicated by the symbol ▽ △, and the wiper blade 50 ' As shown by the arc-shaped arrow, it is easy to swing around the width direction displacement restricting portion (marked with ▽ △), and the ease of swinging is due to the rotating wiper blade 50 'and windshield (glass). It tends to cause judder (chatter) due to friction with the sword, and the generation of judder lowers the wiper wiping performance.

  Further, since the wiper blade 50 'is made of metal, the distance between the side walls has a relatively large manufacturing tolerance due to the influence of the spring back when the side wall is bent, and therefore, the wiper blade 50' is indicated by a symbol ▽ △. Even in the width direction displacement restricting portion, rattling is likely to occur between the side walls and the end of the wiper arm 10 '.

  Further, the metal rivet used as the support shaft 70 has both the side walls of the wiper blade 50 ′ and the wiper arm 10 because the shaft portion extends or the rivet end portion deteriorates due to the load in the width direction over time. A backlash may occur between the ends of the ′.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a wiper connection structure that can suppress the judder generated by the friction between the wiper blade and the windshield and improve the wiping performance of the wiper. It is what.

  The wiper connection structure according to the present invention is a wiper connection structure for connecting a wiper blade and a resin wiper arm, wherein a metal holder base is fixed to the wiper blade, and the width of the holder base is fixed to the width of the wiper blade. A resin-made clip integrally formed with a support shaft extending in the direction is supported, and the wiper arm has a hole formed at its end in the longitudinal direction so as to be rotatable about the support shaft, In a state where the hole is engaged with the support shaft, the holder base and the clip are in contact with each other from the inside, so that displacement in the width direction with respect to the wiper blade is restricted at least at two places having different longitudinal directions. It is characterized by being.

  According to the wiper connecting structure according to the present invention, the wiper arm has a metal holder base and a resin made of at least two different positions in the longitudinal direction when the hole is engaged with the support shaft of the clip. Since the displacement in the width direction relative to the wiper blade is regulated by abutting with the clip from the inside, the rigidity of the connecting portion between the wiper arm and the wiper blade is higher than that of the conventional one, and therefore, the swivel in the width direction. Therefore, judder generated by friction between the wiper blade and the windshield (glass) can be suppressed more than before, and the wiping performance of the wiper can be improved.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, a best mode for carrying out a wiper connection structure of the invention will be described with reference to the drawings. FIG. 1 is a view showing a state in which a rear wiper 100 to which a wiper structure according to this embodiment is applied is mounted on the rear portion of a vehicle 200. The wiper 100 is a so-called snow blade (including a wiper rubber 60). It comprises a wiper blade 50 called a winter blade) suitable for snow wiping and a resin wiper arm 10.

  Here, the snow blade is one in which the entire skeleton structure portion (except for the clip 30 and the holder base 40 described later) other than the wiper rubber 60 is covered with a thin rubber sheet or the like, and snow is applied to the link or the like of the skeleton structure portion. Prevents adhesion and freezing.

  As shown in detail in FIG. 2, the wiper 100 has a metal holder base 40 fixed to the wiper blade 50, and a resin clip 30 supported on the holder base 40, and the wiper arm 10 includes the clip 40. Is engaged and connected.

  A detailed connection structure between the wiper blade 50 and the wiper arm 10 is shown in FIGS. As shown in the drawing, the holder base 40 has two outer walls 42 and 43 that are opposed to each other in the width direction perpendicular to the longitudinal direction of the wiper blade 50 from a bottom plate 41 extending along the longitudinal direction of the wiper blade 50. The bottom plate 41 is fixed to the skeleton structure portion of the wiper blade 50 by screws 51, 51.

  On the other hand, the clip 30 includes two inner side walls 31 and 32 that are respectively inscribed on the outer side walls 42 and 43 of the holder base 40, and the outer walls 42 and 43 are formed by rivets 39 penetrating the outer side walls 42 and 43. On the other hand, it is pivotally supported so as to be able to rotate between a folded state in which both are overlapped and a deployed state in which an angle of approximately 90 degrees is formed (does not overlap). And the support shaft 33 is constructed over both the inner side walls 31 and 32, and this support shaft 33 is integrally molded with both the inner side walls 31 and 32 with resin.

  Further, the width between the inner surfaces 42b, 43b of the outer walls 42, 43 of the holder base 40 is a portion where the inner walls 31, 32 of the clip 30 are inscribed, that is, a portion where shaft holes 48, 48 into which the rivets 39 are inserted are formed. Then, as shown in the plan view of FIG. 4C, it is W5, but the width between the inner surfaces 42c, 43d of the end portions 42a, 43a where the shaft holes 48, 48 are not formed is larger than W5. The width is set to narrow W4 (<W5). A width W4 between the inner surfaces 42c and 43d of the narrow portions 42a and 43a is set to be approximately equal to a width W2 between inner surfaces 31a and 32a of inner walls 31 and 32 of the clip 40 described later.

  On the other hand, the width between the outer surfaces 31b and 32b of the inner walls 31 and 32 of the clip 30 is as shown in the plan view of FIG. 4A in the portion where the shaft hole 38 into which the rivet 39 is inserted is formed. The inner walls 31 and 32 are inscribed in the outer walls 42 and 43 because W3 is set substantially equal to W5. On the other hand, the width between the inner surfaces 31a and 32a of the inner side walls 31 and 32 is set to W2.

  Moreover, as shown in the side view of FIG. 4B, two parallel cuts 35, 35 are formed on both inner side walls, and a portion sandwiched between the cuts 35, 35 is a piece. A cantilever-shaped elastic piece is formed, a finger hooking portion 36 is formed on the free end side of the elastic piece, and a locking claw 37 (locking means) projects outwardly at a portion near the fixed end portion. Has been.

  The locking claws 37, 37 formed on both the inner side walls 31, 32 are shown in FIG. 4 (c) and FIG. 4 (d) in a state where the inner side walls 31, 32 overlap the outer walls 42, 43 (folded state). ) Is inserted into and locked into the locking holes 46 and 46 (locking means) of the outer walls 42 and 43 shown in the side view of FIG. 3, and the clip 30 is prevented from rotating with respect to the wiper base 40. The finger hooks 36 and 36 are accommodated in notches 47 and 47 formed in the outer walls 42 and 43.

  As shown in FIG. 4B, the support shaft 33 formed on the clip 30 is set to have a shaft diameter of d3. However, a predetermined phase range around the support shaft 33 is cut off from the circumferential wall. The finest details are set to a thickness d4 (<d3).

  As shown in FIG. 3, the wiper arm 10 is formed with a hole 16 that engages with a longitudinal end portion 11 of the wiper arm 10 so as to be rotatable around a support shaft 33 of the clip 30. The end portion 11 is formed to be narrower than the general portion other than the end portion 11, and the distance between the narrow side walls 12 and 13, that is, the width of the end portion 11 is set to W1. ing.

  Here, the width W1 of the end portion 11 is set to be approximately equal to the width W2 between the inner surfaces 31a and 32a of the inner side walls 31 and 32 of the clip 30, and as a result, the wiper arm 10 has the side walls 12 and 13 as shown in FIG. The displacement in the width direction with respect to the wiper blade 50 is regulated by contacting the inner surfaces 31 a and 32 a of the inner walls 31 and 32 of the clip 30.

  Further, the distance between the side walls 14 and 15 of the portion slightly closer to the central portion in the longitudinal direction than the end portion 11 of the wiper arm 10 is also set to W1. Of the outer side walls 42 and 43, the protrusions projecting in the longitudinal direction from the inner side walls 31 and 32 of the clip 30, that is, the inner surfaces 42c and 43c of the narrow portions 42a and 43a, respectively, are displaced in the width direction with respect to the wiper blade 50. It is regulated.

  The diameter of the hole 16 formed in the end 11 of the wiper arm 10 is set to d1, as shown in the side view of FIG. 5B, and a part of the peripheral wall forming the hole 16 is The hole 16 is cut out with a width d2 smaller than the diameter d1 of the hole 16 so that the hole 16 communicates with the external space of the wiper arm 10.

  The magnitude relationship among the diameter d1 of the hole 16 of the arm 10, the notch width d2 (<d1), the diameter d3 of the support shaft 33 of the clip 30, and the minimum thickness d4 (<d3) of the support shaft 33 is as follows. It is set like this. That is, the diameter d3 of the support shaft 33 of the clip 40 is set to be slightly smaller than the diameter d1 of the hole 16 of the arm 10 and larger than the notch width d2 (d2 <d3 <d1). Is set to be smaller than the notch width d2 of the arm 10 (d4 <d2).

  The phase relationship between the notch communicating with the hole 16 of the arm 10 and the circumferential wall cut portion of the support shaft 33 of the clip 30 is such that the clip 30 is not overlapped with the outer walls 42, 43. The phase relationship is set such that the support shaft 33 can be engaged with and disengaged from the hole 16 through the notch of the end portion 11 only in the unfolded state rotated with respect to the holder base 40. Specifically, in FIG. 3, in the folded state where the inner side walls 31, 32 overlap the outer walls 42, 43 (the state of the clip 30 indicated by a solid line), the hole 16 of the arm 10 is engaged with the support shaft 33. Alternatively, in the unfolded state (the state of the clip 30 shown by a two-dot chain line) in which the inner side walls 31 and 32 are opened approximately 90 degrees with respect to the outer walls 42 and 43, the support shaft cannot be released from the engaged state 33 is set so that the hole 16 of the arm 10 can be engaged with or disengaged from the engaged state.

  Next, the effect | action of the connection structure of the wiper 100 which concerns on this embodiment is demonstrated.

  First, the operation of attaching (connecting) the wiper blade 50 to the wiper arm 10 coupled to the vehicle 200 will be described with reference to FIG. In the drawing, the wiper arm 10 side is described so as to move with reference to the holder base 40 side fixed to the wiper blade 50, but this is for easy understanding of the movement of the connecting portion. Since the arm 10 is fixed to the vehicle 200, the wiper blade 50 side is actually moved and coupled with the wiper arm 10 side as a reference.

  First, the clip 30 of the wiper blade 50 is folded on the holder base 40 as shown in FIG. 5A. In this state, the locking claw 37 of the clip 30 is engaged with the locking hole 46 of the holder base 40. The clip 30 is prevented from rotating with respect to the holder base 40.

  Next, when connecting the wiper blade 50 to the wiper arm 10, a finger is hung on the finger hook portions 36, 36 of both inner side walls 31, 32, and a load is applied so as to narrow the interval between the both finger hook portions 36, 36. By being added, the elastic piece including the finger-hanging portions 36 and 36 is bent, the locking claw 37 is pulled out from the locking hole 46 and the locking is released, and the clip 30 is rotated with respect to the holder base 40. It becomes an allowed state.

  Then, the clip 30 is rotated about 90 degrees around the rivet 39 and shifted to the unfolded state as shown in FIG.

  At this time, the wiper blade has a phase direction in which the thickness of the support shaft 33 becomes smaller than the width d2 of the notch of the hole 16 of the wiper arm 10 so as to face the notch of the wiper arm 10. 50 and the wiper arm 10 are relatively close to each other, whereby the support shaft 33 is engaged with the hole 16 of the wiper arm 10 as shown in FIG.

  When the clip 30 is rotated around the rivet 39 relative to the holder base 40 and returned to the folded state as shown in FIG. The clip 30 is locked by the locking claw 37 of the clip base 30 in the locking hole 46 of the holder base 40 to prevent the rotation of the clip 30, and the notch of the hole 16 of the wiper arm 10 and the support shaft 33 of the clip 30. The phase relationship with the circumferential wall cut-out portion is shifted, and the engagement / disengagement operation between the wiper arm 10 and the wiper blade 50 is prevented.

  Further, in this connected state, the upper surface 18 of the wiper arm 10 in FIG. 3 and the upper surface of the cover plate 34 connecting the inner side surfaces 31 and 32 of the clip 30 at the upper edge are substantially flush. Thus, the sense of unity in the appearance of the wiper arm 10 and the wiper blade 50 can be enhanced, and the appearance quality is improved.

  Although the above description relates to the action of engaging the wiper arm 10 and the wiper blade 50, the action of separating the wiper arm 10 and the wiper blade 50 that are already engaged is the same as that described above. May be reversed in time series.

  In this manner, in the state where the wiper arm 10 and the wiper blade 50 are coupled, the side walls 12 and 13 of the end portion 11 of the wiper arm 10 are clipped as shown by the symbol ▽ Δ in the plan view of FIG. The side walls 14 and 15 which are in contact with the inner surfaces 31 a and 32 a of the inner side walls 31 and 32 of the 30 and closer to the center portion than the end portion 11 of the wiper arm 10 are narrow portions 42 a of the outer walls 42 and 43 of the holder base 40. , 43a is in contact with each inner surface 42c, 43c.

  Further, the inner surfaces 42 b and 43 b of the outer walls 42 and 43 of the holder base 40 are in contact with the outer surfaces 31 b and 32 b of the inner walls 31 and 32 that are in contact with the side walls 12 and 13 of the wiper arm 10.

  According to the wiper 100 to which the wiper coupling structure according to the present embodiment configured as described above is applied, the wiper arm 10 has a longitudinal direction in a state where the hole 16 is engaged with the support shaft 33. Since the two different side walls 12, 13 and 14, 15 abut against the resin clip 30 and the metal holder base 40 from the inside, displacement in the width direction with respect to the wiper blade 50 is restricted. The rigidity of the connecting portion between the wiper arm 10 and the wiper blade 50 is higher than that of the conventional one. Therefore, judder generated by the friction between the wiper 100 turning in the width direction and the windshield (glass) is suppressed more than the conventional one. And the wiping performance of the wiper 100 can be improved.

  Further, since the support shaft 33 of the clip 30 that engages with the hole 16 of the wiper arm 10 is integrally formed with resin together with both the inner side walls 31 and 32 that support the support shaft 33, both the inner side walls 31 and 32 are provided. It is possible to form the interval between them with high accuracy, and it does not expand greatly even with the use of aging, so the shaft part extends due to the load in the width direction over time, like the support shaft with conventional metal rivets, The wiper arm 10 does not rattle in the width direction due to deterioration of the end of the metal rivet. Therefore, also from this viewpoint, the rigidity in the width direction of the wiper 100 can be improved.

  Moreover, since the support shaft 33 is made of resin like the wiper arm 10, the support shaft 33 is well-familiar with the peripheral wall of the hole 16 of the wiper arm 10, and the sliding resistance during rotation between the two is the same as that of the metal rivet support shaft. Thus, the wiper blade 50 can be smoothly rotated with respect to the wiper arm 10 and the wiper blade 50 can be engaged and disengaged with a light load.

  Further, since the side walls 12 and 13 of the end portion 11 of the wiper arm 10 are in contact with the inner side walls 31 and 32 inscribed in the outer walls 42 and 43 and displacement in the width direction thereof is restricted, the wiper arm 10 The load in the width direction acting on the inner walls 31, 32 of the clip 30 from the side walls 12, 13 is also distributed to the outer walls 42, 43 circumscribing the inner walls 31, 32, and sandwiches the side walls 12, 13. The rigidity of the part can be further improved.

  Further, a part of the peripheral wall forming the hole 16 of the wiper arm 10 is notched with a width d2 smaller than the diameter d1 of the hole 16 so that the hole 16 communicates with the external space of the wiper arm 10. The support shaft 33 is formed with a diameter d3 larger than the notch width d2 and smaller than the diameter d1 of the hole 16, and the inner side walls 31, 32 overlap the outer walls 42, 43 of the holder base 40. Only in the unfolded state in which the clip 30 is rotated with respect to the wiper base 40 so that it does not become necessary, the predetermined phase range has a thickness d4 smaller than the notch width d2 so that the clip 30 can be engaged and disengaged through the notch. Therefore, in the folded state where the clip 30 is overlapped with the holder base 40, the hole 16 of the arm 10 is engaged with the support shaft 33 or detached from the engaged state. Rukoto can not, it is possible to prevent from the wiper 100 used in this folded state, the wiper blade 50 inadvertently falling.

  On the other hand, in a predetermined unfolded state in which the clip 30 is opened about 90 degrees with respect to the holder base 40, the hole 16 of the arm 10 can be engaged with or disengaged from the support shaft 33. The wiper blade 50 can be easily replaced in the deployed state.

  In the folded state where the clip 30 is overlapped with the holder base 40, the clip is locked to the holder base 40 by engaging the locking claw 37 with a locking hole 46 formed in the holder base 40. Therefore, it is possible to prevent the clip 30 from inadvertently shifting to the unfolded state during use of the wiper 100, and to prevent the wiper blade 50 from inadvertently dropping off.

  In addition, an opening 44 is formed in the substantially central portion in the longitudinal direction of the bottom plate 41 of the holder base 30 in the entire width range extending over the lower end edges of the outer side walls 42, 43. The closed bottom plate portion 45 (indicated by a two-dot chain line in FIG. 4 (c)) is cut and raised as shown in FIG. 4 (d).

  In the folded state in which the inner walls 31 and 32 of the clip 30 overlap the outer walls 42 and 43 of the holder base 40, the wiper arm 10 is predetermined with respect to the support shaft 33 as shown in the sectional view of the main part in FIG. Is rotated by a small angle, the upper surface 45a (stopper) of the bent tip portion of the cut and raised bottom plate portion 45 comes into contact with the lower surface 17 of the end portion 11 of the wiper arm 10, and the wiper arm 10 and the wiper blade 50 The relative rotation is restricted.

  As a result, the wiper arm 10 can be prevented from rotating to the engagement / disengagement angle, and the wiper blade 50 can be prevented from unexpectedly falling off.

  Further, the end edges on the wiper blade 50 side of the inner walls 31 and 32 of the clip 30 abut on the bottom plate 41 of the holder base 40 or are separated from the bottom plate 41, so that they directly contact the wiper blade 50. There is no separation. In addition, since the substantially central portion of the bottom plate 41 of the holder base 40 in the longitudinal direction forms an opening 44 over the entire width range across the lower end edges of the outer side walls 42 and 43, the wiper blade 50 of the outer side walls 42 and 43. A part of the lower end edge in contact with the wiper blade 50 is cut out, and a gap 44 is formed between the wiper blade 50 and the wiper blade 50 as shown in FIG.

  Therefore, even in the state shown in FIG. 1 in which the wiper 100 is attached to the vehicle 200, between the inner walls 31 and 32 of the clip 30, between the outer walls 42 and 43 of the holder base 40, or with these outer walls 42 and 43. Even if raindrops or the like enter between the bottom plate 41, the water such as raindrops flows down below the wiper 100 through the gap 44 or the like, and the draining performance can be improved.

  In particular, in a low temperature environment in which a so-called snow blade is used as the wiper blade 50, if water stays in the connecting structure portion such as the clip 30 or the holder base 40, the water freezes and the blade 50 cannot be replaced. Therefore, the improvement of the draining performance can avoid these inconveniences and is more useful.

  In the present embodiment, the description has been made assuming that a snow blade is applied as the wiper blade 50. However, the wiper connection structure according to the present invention is not limited to the snow blade, and a link or the like is exposed to the outside. Of course, the present invention can also be applied to general wiper blades.
