Description

[0001]
[Industrial applications]
The present invention relates to an improvement in a vehicle wiper, and more particularly to a vehicle wiper that can be assembled with one touch.
[0002]
[Prior art]
Generally, a vehicle wiper wipes raindrops attached to a front glass and a rear glass of a vehicle to improve visibility.
The general structure of the vehicle wiper will be briefly described. A swing member having a drive mechanism for swinging left and right and a clip fixed to the tip, a blade lever detachably attached to the clip, A blade support member is swingably connected to the blade lever by rivets, and a blade rubber supported by the blade support member and wiping the glass surface.
[0003]
It should be noted that a mechanism for keeping the blade rubber in contact with the glass surface and a mechanism for keeping the blade rubber at an appropriate contact angle with respect to the glass surface in both upward and downward directions in which the blade rubber wipes the glass surface are provided. , Of course.
[0004]
[Problems to be solved by the invention]
However, in the conventional vehicle wiper, since the blade lever and the blade supporting member are connected by rivets or similar parts, the number of man-hours for caulking the rivet is increased, resulting in poor work efficiency. was there.
[0005]
[Means for Solving the Problems]
A vehicle wiper according to the present invention swings left and right by a drive mechanism, a swing member having a clip fixed to a tip, a blade lever detachably attached to the clip, and a swingable swingable blade. In a vehicle wiper comprising: a blade support member connected to the blade support member; and a blade rubber supported by the blade support member and wiping a glass surface, the blade lever has a U-shaped cross section, An embossed projection is formed on the surface, and the blade supporting member is provided with through holes on both side surfaces of the U-shaped fulcrum portion formed in the intermediate portion, and a cut-out portion is provided so as to surround the through hole, and the U-shaped fulcrum is provided. the spring is imparted to the parts, embossing projections formed on one end of the blade lever, directly engage then together the Toruana provided in a U-shape fulcrum of the blade support member A resin film having a through-hole provided on a wall surface covering the cut-away portion so as to avoid an engagement portion between an embossed projection of the blade lever and a through-hole of the blade support member is provided by the blade lever and the blade. It is configured to be inserted between the support member .
Further, in addition to the above configuration, a punching portion is provided above the through hole of the blade support member.
[0006]
[Action]
According to the present invention, since the blade lever is connected only by pushing the blade support member into the blade lever, the number of working steps can be significantly reduced.
[0007]
【Example】
FIG. 1 is a partial schematic side view showing one embodiment of a vehicle wiper according to the present invention, and FIG. 2 is an exploded perspective view showing a part of FIG. 1 in an enlarged manner. In the drawing, reference numeral 1 denotes a blade lever having a U-shaped cross section. One end (not shown) of the blade lever 1 is detachably attached to a clip (not shown), and embossed protrusions 1B are provided on both side surfaces of the other end 1A. , 1B.
[0008]
Reference numeral 2 denotes a Teflon film, and the Teflon film 2 is a U-shaped member having a cross-sectional shape, and through holes 2A, 2A are provided on both side surfaces thereof. Then, the through holes 2A, 2A are locked and attached to the embossed protrusions 1B, 1B inside the other end 1A of the blade lever 1. Reference numeral 3 denotes a blade support member, and through-holes 3B, 3B (only one is shown) are provided on both side surfaces of a U-shaped fulcrum 3A formed at an intermediate portion of the blade support member 3.
[0009]
The U-shaped fulcrum 3A of the blade support member 3 is provided with cutouts 3C, 3C so as to enclose the through holes 3B, 3B, and the cutouts 3C, 3C are formed by forming the cutouts 3C, 3C. The character-shaped fulcrum portion 3A is provided with a spring property. The U-shaped fulcrum 3A is formed with inwardly projected portions 3D, 3D. When the U-shaped fulcrum 3A is inserted inside the Teflon film 2, the embossed portions 3D, 3D are formed. Can easily spread the embossed protrusions 1B, 1B of the blade lever 1, and the through holes 3B, 3B can be smoothly inserted into the embossed protrusions 1B, 1B.
[0010]
In addition, since the blade lever 1 is formed by forming a thin steel plate into a U-shape, the embossing 1C provided on the blade lever 1 is for reinforcement. Similarly, the embossing 3E provided on the blade supporting member 3 is for reinforcement.
[0011]
As for the assembling operation of the vehicle wiper having this configuration, the blade lever 1 is attached to the embossed protrusions 1B, 1B inside the other end 1A of the blade lever 1 by engaging with the through holes 2A, 2A of the Teflon film 2. Then, the through holes 3B, 3B of the U-shaped fulcrum portion 3A of the blade support member 3 are locked, and can be rotatably connected.
[0012]
Note that the Teflon film 2 is not limited to this, and it is a matter of course that various resin films can be used. In addition, when the blade lever 1 and the blade supporting member 3 are locked, particularly when the blade lever 1 smoothly rotates, it is not necessary to insert the Teflon film 2 therebetween.
[0013]
【The invention's effect】
As described above in detail, according to the vehicle wiper according to the present invention, since the blade support member is simply pushed into the blade lever and is rotatably connected with one touch, the number of work steps can be significantly reduced. And can be manufactured at low cost.
Furthermore, when the vehicle wiper is used by covering it with an antifreeze cover, there is no projection on the outer surface of the other end of the blade lever, so that the antifreeze cover is not rubbed and broken. There is.
