The specific embodiment
Followingly be elaborated according to the specific embodiment of accompanying drawing to the utility model.
The swept area of wiper blade 11 of a kind of embodiment of the utility model shown in Figure 1 is formed in the wiper device 12 that is provided with on the not shown vehicle such as manned vehicle.Wiper device 12 has windscreen wiper arm 13, and swept area of wiper blade 11 is installed in the front end of windscreen wiper arm 13, with the glass for vehicle window (vehicle window front windshield) of wiping vehicle.
Swept area of wiper blade 11 has blade rubber 21 and scrapes horse 22.
Scrape the injection moulding formation of horse 22 through resin material, its cross sectional shape is " コ " font.The length dimension of scraping horse 22 is approximately the half the of blade rubber 21, and covers the centre portion of blade rubber 21.In addition, scrape horse 22 and engage with blade rubber 21, scraping on these 2 of horse 22, scrape horse 22 along on the direction of glass surface, but free bend ground keeps blade rubber 21 at the both ends of its length direction.
Scrape on the two ends of length direction of horse 22 and be respectively arranged with scraping blade cover 23.These scraping blade covers 23 form the shape of cross section for " コ " word by the injection moulding of resin material,, can be connected with rotating freely and scrape on the horse 22 along near the direction away from (near from anti-) glass for vehicle window at its base end part.Scraping blade cover 23 covers blade rubber 21 from scraping the front part that horse 22 is given prominence to, and simultaneously, when blade rubber 21 was crooked along glass surface, scraping blade cover 23 can be according to this bending with respect to scraping horse 22 rotations.
The roughly centre portion of scraping the length direction of horse 22 is provided with arm link 31, is connected the front end of windscreen wiper arm 13 through making these arm links 31, swept area of wiper blade 11 is installed in the front end of windscreen wiper arm 13.
Scraping horse 22 is provided with to install and uses perforate 22a, arm link 31 to be arranged on this installation with in the perforate 22a.Install with being provided with rotary supporting part 32 in the perforate 22a.Rotary supporting part 32 forms the bearing pin shape, is set to use perforate 22a with wiping direction crosscut abreast installation.
As shown in Figure 2, the front end of Wiper arm 13 is provided with the hook portion 13d of " U " font, engages with arm link 31 through making this hook portion 13d, and swept area of wiper blade 11 connects (installation) front end to windscreen wiper arm 13.Be provided with supporting walls 31b integratedly with connecting portion 31a on the both ends of the connecting portion 31a of arm link 31; The hook portion 13d that engages with arm link 31 is arranged between these supporting walls 31b, and shaking and rocking on the wiping direction that with connecting portion 31a is the center is inhibited.In addition; When hook portion 13d engages with arm link 31; The claw 31c1 that is arranged on the card stopping bar 31c on the arm link 31 is fastened in the stop hole 13e of hook portion 13d, prevents that windscreen wiper arm 13 breaks away from from arm link 31, prevents that promptly swept area of wiper blade 11 from coming off from windscreen wiper arm 13.
As shown in Figure 5, in the swept area of wiper blade 11 of the utility model, be arranged on the rotary supporting part 32 scraped in the horse 22 by with to scrape horse 22 identical materials be resin material with to scrape horse 22 integrally formed.In this embodiment, the injection moulding of rotary supporting part 32 through resin material with scrape horse 22 and form as one.In this way, rotary supporting part 32 can be to scrape in the operation of horse 22 with to scrape horse 22 integrally formed through injection moulding at resin material.
Like this; Owing to be used for to rotate freely the rotary supporting part 32 of ground hold-down arm link 31 and scrape horse 22 integrally formed; And need as swept area of wiper blade in the past, must not carry out the work that rotary supporting part 31 is set scraping on the horse 22; For example prepare and scrape the metal pin parts that formation left in 22 minutes by horse, and these parts are fixed in the hole that on scraping horse 22, is provided with through the mode that is pressed into, or similar work.Therefore can easily make swept area of wiper blade 11, in this swept area of wiper blade 11, arm link 31 can support by scraping horse 22 with rotating freely.
In addition and since rotary supporting part 32 with scrape horse 22 and form by resin material equally, therefore through the injection molding job operation of use, can easily form have a rotary supporting part 32 scrape horse 22.
The present invention is not limited to previous embodiment, in the scope that does not break away from its main points, can carry out multiple change.
For example, in the aforesaid specific embodiment, scrape horse 22 and be formed from a resin, but be not limited to this, form also by other materials such as cast aluminiums and be fine with rotary supporting part 32.
