Abstract
In connecting brackets using a frame member for a wiper device, the frame member being of linear structure providing sufficient mechanical intensity, the brackets are formed of die cast employing a general purpose die referenced to the axes of sleeves for pivotal shafts. An axis A of the frame member is so arranged that it is contained in the third imaginary plane which is parallel with first and second imaginary planes, wherein the first and second imaginary planes are selected respectively from imaginary planes which contain an axis B of a first pivotal shaft and from imaginary planes which contain an axis C of a second pivotal shaft 6, so that the first and second imaginary planes are parallel with each other.
Claims13
A modular-type wiper device comprising:
- a first bracket having a first sleeve, a first mounting portion and a motor base portion, said first sleeve receiving a first pivotal shaft, said first mounting portion for securement to a vehicle's body and said motor base portion for supporting a wiper drive motor;
- a second bracket having a second sleeve and a second mounting portion, said second sleeve receiving a second pivotal shaft, said second mounting portion for securement to a vehicle's body, said first and second brackets being formed of a one-body die cast, said first and second brackets each having a connecting portion formed thereon;
- and
- a linear frame member having two end portions, each end portion of said linear frame member being connected to one of said bracket connecting portions to form a modular bracket construction, wherein the linear frame member has an axis contained in a third imaginary plane, said third imaginary plane being parallel to a first imaginary plane and a second imaginary plane, said first imaginary plane being selected from a plurality of imaginary planes containing said first pivotal shaft and said second imaginary plane being selected from a plurality of imaginary planes containing said second pivotal shaft, said first and second imaginary planes being parallel to one another.
A modular-type wiper device comprising:
- a first bracket having a first sleeve, a first mounting portion and a motor base portion, said first sleeve receiving a first pivotal shaft having an axis, said first mounting portion for securement to a vehicle's body and said motor base portion for supporting a wiper drive motor;
- a second bracket having a second sleeve and a second mounting portion, said second sleeve receiving a second pivotal shaft having an axis, said second mounting portion for securement to a vehicle's body, said first and second brackets each having a connecting portion formed thereon;
- and
- a linear frame member having two end portions, each end portion of said linear frame member being connected to one of said bracket connecting portions to form a modular bracket construction, wherein one of said pivotal shaft axes appears as a straight line when said pivotal shafts are viewed such that the other of the pivotal shaft axes appears as a point, and the linear frame member has an axis which appears parallel to said straight line.
