JPH0589126U - Leaf spring type wiper blade with integrated arm - Google Patents

Abstract

(57) [Summary] (Modified) [Purpose] The wiper blade has a simple structure, and the spine of the blade is connected to an arm on its extension line, or
By integrating, it is to create an epoch-making wiper system with a slender, smart and beautiful outline. [Structure] The wiper blade is a leaf spring type 4, and one end of the wiper blade spine 1 is connected to or integrated with one end of the wiper arm on its extension line, and is attached to both ends of the spine 1. The leaf spring 3 is attached so that the tip of the leaf spring 3 does not protrude from both ends of the spine, and the leaf springs 4 at both ends join the both ends of the leaf spring 4 to which the rubber 5 is attached, so that the pressing force of the arm directly applies to the entire spine. In addition, it acts on the leaf springs 3 at both ends to press the rubber 5 against the glass surface.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a wiper blade that is connected to or integrated with an arm on an extension line of a blade spine.

[0002]

[Prior Art]

 Since the conventional blade has a structure in which rubber is held by a plurality of large and small arcuate attachments, there is no way to apply the pressing force of the arm to the blade except to apply it to the center of the spine. The resulting combination of blade and arm, together with the complicated structure of the blade with an arched fitting, has made the wiper system awkward and bulky, and the pursuit of a sleek, sleek and beautiful outline. Was essentially impossible.

[0003]

[Problems to be solved by the device]

 The structure should be simple without the use of bow-shaped attachments, and the method of connecting the arm and blade should be performed on the extension line of the spine.

[0004]

[Means for Solving the Problems]

 Due to the simple structure of the leaf spring type, the thickness of the spine overlaid on the thickness of the rubber was thinner and cleaner than the conventional bow blade. In addition, the spine of the leaf spring blade is connected to the arm on its extension, or even if it is integrated, it has the property of transmitting the holding force of the arm to the leaf springs at both ends as it is. In addition, integration was possible and the cause of bulkiness could be removed.

[0005]

【Example】

 As shown in FIG. 2 showing one embodiment, one of the spines is used by connecting it to the distal end of the thin portion of the arm except for the thick portion containing the spring including the arm head.

As shown in FIG. 3 showing an embodiment, one of the spines is used integrally with the tip of the thin part of the arm on its extension line.

As shown in FIG. 4 showing an embodiment, the blade is used by being combined with the arm in various centrally practiced methods in the center of the back of the blade.

As shown in FIG. 5 showing one embodiment, the upper edge of the spine is formed to have a high shape, and the thin spine is reinforced for use.

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

In the case of a curved blade, the spine bent along the curved surface of glass is used.

[0011]

[Effect of the device]

 The ultimate goal of the present invention is to find a way to develop a wiper system that is as slender and sleek as possible, and to develop a wiper system that is as unobtrusive as possible. Since it can be configured with various skeletons, and it can be connected and integrated with the arm on the extension line of the spine, it is possible to induce various innovations regarding a completely new type wiper system with a slender and sleek beautiful shape Created sex.
