る。DETAILED DESCRIPTION OF THE INVENTION The present invention provides a connector that allows a wiper of the same type to be attached to a wiper already installed in an automobile very easily and robustly.

種々の利点がある。 Conventionally, there has been a double wiper as an optional part for automobiles, which has two wipers installed side by side.Compared to a single wiper, this double wiper has lower operating noise, greater cleaning and wiping effect, and has a rubber blade. It has various advantages such as long service life.

な自動車以外には殆んど取り付けられていないの
が実情である。 However, since the normal sales specifications for automobiles are single wipers, if you do not special order double wipers when purchasing a new car, you will have to purchase double wipers separately and replace them with the existing wipers. This double wiper is relatively expensive and is very uneconomical since it eliminates the need for a separate wiper. For this reason, the reality is that double wipers are rarely installed on cars other than special cars such as rally and dirt trial cars.

本考案は、上記のような点に鑑みてなされたも
ので、既設のワイパーにこれと同種類のワイパー
を並行に取り付けてダブルワイパーに変更出来る
連結具を提供することを目的とするものである。 The present invention was made in view of the above points, and the purpose is to provide a connector that can be used to convert an existing wiper into a double wiper by attaching wipers of the same type in parallel. .

以下、本考案の自動車用ワイパーの連結具を、
其の実施例を示した図面に基づいて詳説する。 Below, the automotive wiper connector of the present invention is as follows:
This embodiment will be explained in detail based on the drawings showing the embodiment.

なつている。 Figure 1 shows one embodiment of the present invention, and Figures 2 to 4 show an embodiment of the present invention.
The figures each show a double wiper constructed using a connector according to an embodiment, in which 1 is a holder, 2 is a
Reference numeral 3 indicates a support body, and 3 indicates a screw for fixing the holding body 1 and the support body 2 together. The holding body 1 has automobile wipers 4, on both sides in the longitudinal direction on the lower surface.
A retaining groove 1a having a cross-sectional shape corresponding to the cross-sectional shape (inverted U-shape in this case) of the secondary supports 4a, 5a of No. 5 is formed in the transverse direction, and a pair of screw holes are provided at appropriate positions on the lower surface 1b is formed. on the other hand,
The support body 2 has a pair of slightly elastic support pieces 2a extending from the upper edges of both ends of the rectangular main body, and the support pieces 2a are arranged at positions facing each of the holding grooves 1a on the upper surface of the support pieces 2a. , secondary support 4a
The secondary support 4a has an outer shape corresponding to the inner shape of the secondary support 4a.
A pair of supporting protrusions 2b are formed to press and fix the holder into the holding groove 1a, and insertion holes 2c for screws 3 are formed in the main body at positions facing each of the screw holes 1b of the holder 1. has been done. The wiper 4 is well known in that arc-shaped primary supports 4c are fixed to both ends of the blade 4b, and a secondary support 4a is arranged between the two primary supports 4c. Both ends are pivoted and straddled, and both primary supports 4c are connected to the second
The blade 4b is curved in accordance with the curved surface of the windshield of the automobile by rotating using both ends of the second support 4a as fulcrums, respectively.
In such a case, the rotation of the primary support 4c is controlled by the support piece 2a.
The lower surface of the support piece 2a is an inclined surface so that the support piece 2a does not get in the way.

る。 When making a double wiper using the coupling device of the above-configured embodiment, purchase a wiper 5 of the same type as the wiper 4 already installed in the car, and install this wiper 5 parallel to the existing wiper 4 at a predetermined interval. As shown in Figure 3,
First, both wipers 4 and 5 are inserted into both holding grooves 1a of the holding body 1.
The holding body 1 is assembled by loosely fitting each of the secondary supports 4a and 5a.
across both wipers 4 and 5. Then support 2
The supporting protrusions 2a are inserted into the recesses of the secondary supports 4a and 5a, and the supporting body 2 is superimposed on the holding body 1 from below, and then the screw 3 is inserted from below into the insertion hole 2c. By screwing into the screw hole 1b and tightening, each secondary support 4a of both wipers 4, 5,
5a are gripped and fixed at both ends of the holder 1 and the support 2. This connector, as shown in Figure 2,
By providing the wipers at two locations, both wipers 4 and 5 are firmly fixed without wobbling, resulting in a double wiper.

ば良い。 By the way, in the above embodiment, the blade 4b has a diameter of 40 mm.
cm, and the secondary supports 4a and 5a are inverted U cross-sections.
Although the description has been made for the wipers 4 and 5 that are shaped like the letter 4, for wipers with slightly different shapes, the holding grooves and supports of the holding body may be modified to correspond to the cross-sectional shape of the secondary support. It is sufficient to determine the shape of the supporting protrusion of the body. In other words, the retaining groove and the support are arranged so that the cross-sectional shape of the gap created between the groove wall of the retaining groove and the surface of the supporting protrusion when the retainer and the support are joined matches the cross-sectional shape of the secondary support. What is necessary is to determine the shape of the supporting protrusion.

次に各種のワイパーに適用出来る連結具を例示
した第５図乃至第７図に付いて説明する。 Next, a description will be given with reference to FIGS. 5 to 7, which illustrate examples of connectors that can be applied to various types of wipers.

断面形状に合致するように設計されている。 Figure 5 is for a wiper with a blade of approximately 25 to 28 cm and a secondary support that has an inverted dish-shaped cross section. Figure 6 is for a wiper that has a blade of approximately 40 cm and a secondary support that has a cross-sectional shape. Figure 7 shows a wiper with a blade of about 45 cm and a secondary support slightly smaller in shape than the wiper to which the connector shown in Figure 6 is applied. 13 and supporting grooves 11a to 13a and support protrusions 21 formed on supports 21 to 23, respectively.
The shapes of b to 23b correspond to the holding grooves 11a to 13a when the supports 21 to 23 are joined to the holders 11 to 13.
The cross-sectional shape of the gap between the groove wall and the surface of the supporting projections 21b to 23b is designed to match the cross-sectional shape of the secondary support of the wiper to which the wiper is applied.

的効果を発揮するものである。 As mentioned above, according to the automobile wiper coupling of the present invention, it is possible to extremely easily attach the same type of wiper to the existing wiper of the automobile and convert it into a double wiper, and the existing wiper can be used. It is very economical as you only need to purchase the missing wiper, and since the holding body and support body are combined with screws, it is easy to remove one wiper if necessary. , and has excellent robustness, and the present invention exhibits remarkable practical effects.
