Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a vehicle wiper device for mounting a wiper device for wiping a window surface of a vehicle.

[0002]

[Problems to be Solved by Prior Art and Invention]

 Generally, in this type of wiper device, a wiper shaft is incorporated so as to penetrate a plate material such as a glass plate or a body plate, but in that case, the length of the wiper shaft varies depending on the type of vehicle or grade. There is. By the way, since the amount of protrusion of the wiper shaft from the plate member is set to be substantially constant due to the relationship of the wiper arm, the difference in length of the wiper shaft is caused by the frame assembly on the frame side on which the wiper shaft is pivotally supported. It will be absorbed by adjusting the insertion position, but at that time, the gap between the frame and the plate material will differ, and it will be unavoidable to assemble a sleeve (spacer) of different length into this gap. However, preparing sleeves of different lengths one by one is not contradictory to the common use of parts, and also causes the complexity of parts management.

[0003]

[Means for Solving the Problems]

 The present invention was devised with the object of providing a vehicular wiper device capable of eliminating these drawbacks in view of the above-mentioned circumstances, and includes a shaft support portion projectingly formed on a case frame. In a wiper device configured such that a protruding wiper shaft is penetrated through a plate material such as a glass plate in a state where a sleeve is interposed, and a wiper arm is attached to a protruding tip end portion of the wiper shaft, an outer periphery of the shaft support portion is provided. A plurality of reinforcing ribs whose tip is set to differ from perspective to the tip of the shaft support part are formed at a predetermined angle, while a cylindrical part is formed at the base end of the sleeve so as to be externally fitted to the tip part of the shaft support part. Then, a plurality of slits having different lengths are formed on the tubular portion at a predetermined angle, and the recessed amount of the tubular portion with respect to the shaft support portion can be adjusted by selectively fitting the slits to the reinforcing ribs. Configured It is an feature.

According to this structure, the present invention allows one sleeve to be incorporated into a frame having a different gap between the frame and the glass plate.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes a case frame of a wiper motor for a rear wiper, which is integrally attached to a body side, and a cylindrical shaft supporting portion 1a is projectingly formed from the case frame 1, and forward and reverse rotation is performed from the shaft supporting portion 1a. Although the wiper shaft 2 for driving is projected, first and second reinforcing ribs 1b, 1c are alternately formed on the outer periphery of the shaft supporting portion 1a at intervals of 90 degrees. The reinforcing ribs 1b and 1c are set to have a long tip whose tip extends substantially to the tip of the shaft support portion 1a and a short tip which has a gap therebetween.

The wiper shaft 2 penetrates the glass plate 5 with a sleeve 3 and a cushioning material 4 according to the present invention, which will be described later, interposed therebetween, and a base end of a wiper arm 6 is integrally formed at a tip end exposed to the outside. It is the same as the conventional one. Here, 7 is a nut for supporting the sleeve 3, 8 is a waterproof cap, and 9 is a nut for fixing the wiper arm 6 to the wiper shaft 2.

The sleeve 3 has a tubular shape such that a base end portion thereof is externally fitted to the shaft support portion 1 a. The tubular portion 3 a corresponds to the first and second reinforcing ribs 1 b and 1 c. As shown in the figure, two types of first and second slits 3b and 3c, long and short, are formed alternately at intervals of 90 degrees. Then, the sleeve 3 is assembled so that the short second slit 3c is selected and fitted to either the first reinforcing rib 1b or the second reinforcing rib 1c, so that the sinking amount with respect to the shaft supporting portion 1a is switched. It is adjusted so that it can be used for two types of things in which the gap between the case frame 1 and the glass plate 5 is different.

In the embodiment of the present invention configured as described above, when a wiper device is incorporated, there are two types in which the amount of protrusion of the wiper shaft 2 from the shaft support portion 1a differs depending on the type of vehicle or the like. The case frame 1 is attached to the glass plate 5 at different positions in the perspective, and in this case, the sleeve 3 has a long second slit 3c when the wiper shaft 2 has a long protrusion amount. The tubular portion 3a is externally fitted to the shaft support portion 1a so as to be fitted to the first reinforcing rib 1b (in this case, in the embodiment, the first slit 3b is set to a dimension not fitted to the second reinforcing rib 1c). However, it is also possible to fit them), so that the amount of immersion in the shaft support portion 1a can be reduced, and the wiper shaft 2 with a long protrusion amount can be accommodated. Amount of protrusion When the length is short, the second slit 3c is fitted to the short second reinforcing rib 1c, and the first slit 3b is fitted to the long first slit 1b so that the cylindrical portion 3a is not attached to the shaft supporting portion 1a. By fitting, the amount of immersion in the shaft support portion 1a is increased, and the wiper shaft 2 having a short protrusion amount can be accommodated. As a result, even one type of sleeve 3 can be assembled in two ways, and the parts can be shared in a reliable manner. In addition, this has an advantage that the sleeve assembling can be switched by effectively utilizing the reinforcing ribs 1b and 1c for reinforcing the shaft supporting portion 1a.

It should be noted that the present invention is not limited to the above-mentioned embodiment, and for example, a pair of reinforcing ribs are provided on the outer circumference of the case frame shaft supporting portion with an interval of 180 degrees. On the other hand, two pairs of long and short slits are alternately formed on the sleeve tubular part at 90 degree intervals, and either long or short slit is selected and fitted to the reinforcing rib. It is also possible to adjust the amount of immersion of the tubular portion with respect to the shaft support portion. Further, the adjustment of the amount of sleeving of the sleeve into the shaft support is not limited to two, but can be set to any number, such as three or four, and can also be performed on the front wiper. .

[0010]

[Operation effect]

 In summary, since the present invention is configured as described above, when incorporating a wiper device, when the protrusion amount of the wiper shaft from the shaft support portion differs depending on the type of vehicle etc. The sleeve case can be fitted by appropriately selecting and fitting slits with different lengths formed on the sleeve tubular part to the reinforcing ribs formed on the outer periphery of the shaft support part so that they are different from each other in the perspective of the tip of the support part. It is possible to adjust the amount of immersion for the frame shaft support. As a result, even with one type of sleeve, various installations can be made according to the length of the protrusion of the wiper shaft from the shaft support portion, and the parts can be shared. Moreover, this one has the advantage that the sleeve assembly can be switched by effectively utilizing the reinforcing ribs for reinforcing the shaft support portion.
