Abstract

(57) [Abstract] [Purpose] A leaf spring type wiper blade is used to open the way to the development of a wiper system that has a simple structure and low air resistance, is smart and sharp, and is as unobtrusive as possible. is there. (Structure) The ends of the leaf springs on both ends of the spine of the wiper blade are joined to both ends of a leaf spring with blade rubber attached.When the load is applied to the spine by the pressing force of the wiper arm, it acts on the leaf springs on both ends. , The rubber with the leaf spring attached is pressed against the wind glass surface to make a close contact, and a nearly even load is obtained over the entire surface, so that even when the blade reciprocates, it can instantly adapt to the slight changes in the curved surface of the glass. Was done

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a wiper blade having a simple structure and low air resistance.

[0002]

[Prior Art]

 Conventional blades are configured so that rubber is held by multiple small and large arcuate attachments, and the central portion of the arched spine is loaded by the arm pressing force to directly press the rubber against the glass surface for close contact. It was Although there was almost no problem functionally, there was a problem in that the structure of multiple arcuate fixtures was complicated, bulky, and had high air resistance.

[0003]

[Problems to be solved by the device]

 A simple structure is to reduce air resistance.

[0004]

[Means for Solving the Problems]

 A leaf spring type was used to make the structure simple. By utilizing the elasticity of the leaf springs at both ends of the blade's spine and the leaf springs attached to the rubber, not only can the rubber be pressed against the glass surface to adhere to it like the conventional blade, but also the leaf spring Elasticity further enhances the degree of adhesion. Also, since the spine is plate-shaped, the air resistance has become so small that it is not comparable to the conventional one. It should be noted that various suitable examples are possible depending on the shape and size of the blade used and the state of the glass surface.

[0005]

【Example】

 In the case of a flat blade, a flat spine is used.

In the case of a curved blade, the spine is curved.

The leaf springs at both ends of the spine and the bent leaf springs to which rubber is attached are connected to each other in a state of being extended to a plane as shown in FIG.

As shown in FIG. 2, the leaf springs at both ends of the spine and the flat leaf springs to which the rubber is attached are combined and used as they are.

As shown in FIG. 3, the leaf springs at both ends of the spine and the curved leaf springs to which the rubber is attached are used in the state as they are.

Leaf-spring blades are used in the central portion of the spine in conjunction with the arms in various ways currently in practice.

The leaf spring blade is used at one end of the spine in combination with the arm in various ways currently in practice. In the case of the flat shape, there is no problem, but in the case of the curved shape, it is convenient for the connection if the spine is deformed as shown in FIG.

When the tip ends of the leaf springs at both ends of the spine and the both ends of the leaf springs attached with rubber are joined, a flat type may be used as shown in FIG. 2 showing one embodiment, but a curved type is used in the case of a curved type. A hinge type as shown in FIG. 1 showing an embodiment is preferable.

[0013]

[Effect of the device]

 The ultimate goal of the present invention is to open the way for the development of a wiper system that is smart, sharp, and as unobtrusive as possible, but by using blades of a leaf spring type, it is composed of a simple plate-like skeleton. Therefore, not only was the blade bulk reduced, but also the air resistance was reduced. This groundbreaking effect has triggered various innovations in new types of wiper systems.

[Brief description of drawings]

FIG. 1 is a cross-sectional view illustrating a state in which a bent leaf spring having a rubber attached thereto is extended to a flat surface and coupled.

FIG. 2 is a cross-sectional view illustrating a state in which a flat plate spring having a rubber attached is directly connected.

FIG. 3 is a cross-sectional view illustrating a state in which a curved leaf spring with a rubber attached is directly connected.

FIG. 4 is a cross-sectional view showing a method of deforming the spine, which is convenient for connecting one end of the spine of the curved blade to the arm.

Claims (1)

[Scope of utility model registration request] 1. A leaf spring wiper blade comprises a blade rubber (3) (hereinafter rubber) at the tip of a leaf spring (2) at both ends of the spine of the wiper blade (hereinafter referred to as blade) of FIG. 1 showing an embodiment. A leaf spring (4) attached to both ends of the wiper arm (hereinafter,
When a load is applied to the spine by the pressing force of the arm),
By acting on the leaf springs at both ends, the rubber to which the leaf springs are attached is pressed against the wind glass (hereinafter referred to as glass) surface and comes into close contact, resulting in an almost even load, and even when the blade reciprocates, the glass is flat. Of course, even if the curved surface changes subtly, it can be instantly adapted to the curved surface. A blade characterized by a simple structure and low air resistance.
