Description

Wiper Blades with Curvature Supported Articulated Spoilers

The present invention relates to a wiper blade including a curvature-supported articulated spoiler, the curvature of which is supported by a spoiler having a multi-joint shape.

In the wiper device, which is a means to clean the foreign matter (rain, snow, dust, etc.) on the window surface while turning (rotating) at a constant radius according to the user's operation,

At the same time, one secondary is connected to each side of the main metal primary, such as the initial tournament type.

Under each secondary, a number of lever-type yokes (members without self-tension), which are operated in the form of tournaments in conjunction with the secondary action of the secondary, are provided with a swing type to hold the wiper strip to equalize the pressure on the curved surface of the window. And configured to enable precise curvature tracking,

Above each of the main primary and the secondary secondary, a spoiler (an element which prevents the phenomenon of being injured by air during high-speed driving) having an articulated connection structure capable of being injection-molded with a hard plastic material and capable of angling at an angle. Installed articulated uni-blade wipers have already been known.

However, in the conventional articulated uni-blade wiper device, since the function of equal pressure and precise curvature support on the curved window surface is substantially achieved by the lever type yoke that operates in the form of tournament in connection with the second and second,

In addition to the spoiler, at least one of the secondary and the lever-type yoke must be further configured, so that the assembly and manufacturing process of the wiper device was complicated and costly had to be increased.

Therefore, in the present invention, rather than supporting the curvature by a separate configuration, such as the secondary and lever-type yoke as in the prior art, a rubber blade fitted with a rail spring for each of the articulated elements together with the articulated function including the car joint joint Each of the upper end of each of the individual swinging type, the spoiler, which is an essential part of the wiper blades (or the car wiper device), is operated by two or more pieces of the spoiler itself. With the newly established system that enables equal support for curvature, the wiper includes a curvature-supported articulated spoiler that greatly simplifies the manufacturing and assembly process, as well as reducing costs and safety of performance and quality. The focus was on providing blades and the technical challenges were completed.

The present invention for achieving the above technical problem, in the configuration of the left and right spoiler 300 composed of both sides of the base cover 130, among the components of the wiper blade, each of two or more nodal spoilers 230 After separating and configuring, and each of the separate spliced spoiler 230 is coupled to each other by articulating joint articulation means (240) to each other; Under each of the articulated spoilers 230 connected by articulated joints, the upper head 111 or the upper end of the rail spring 120 above the rubber blade 110 is individually gripped, respectively, to locally cover the curvature surface of the automobile window. An individual rocking tongs 250 is formed to support it; The length of each of the knot-shaped spoilers 230 connected by the articulated joint is one or more and one or more other may be applied differently.

As described above, the wiper blade including the curvature-supported articulated spoiler of the present invention has a simpler structure than the conventional uni-blade wiper, even though the structure of the wiper blade is much simpler. By making it possible, it is a useful invention that can contribute greatly to the assembly and productivity of the wiper product and the cost reduction effect.

The wiper blade including the curvature-supported articulated spoiler of the present invention will be described in more detail based on the accompanying drawings.

In the present invention, among the components of the wiper blade to wipe off the foreign matter (rain, snow, dust, etc.) on the window surface while turning (rotating) to a certain radius according to the operation,

The left and right spoilers 300 constituted by both sides of the base cover 130 are respectively configured by two or more nodal spoilers 230, and then separated between the nodal spoilers 230. The articulated coupling means 240 is coupled to each other by connecting each other;

Under each of the articulated spoilers 230 connected by articulated joints, the upper head 111 or the upper end of the rail spring 120 above the rubber blade 110 is individually gripped, respectively, to locally cover the curvature surface of the automobile window. An individual rocking tongs 250 is formed to support it;

The length of each of the knot-shaped spoilers 230 connected to the articulated joints is characterized in that any one or more and one or more other can be applied differently.

In addition, when one or more and one or more different lengths of the node-shaped spoilers 230 assembled in multiple joints are different from each other, a part consists of an on-body spoiler 230 having the same length and the other part. The half spoiler 210 may be configured to have a length smaller than the on-body spoiler 230 (preferably half the length of the half of the on-body spoiler).

In some cases, as in the above, a part is composed of the whole node spoiler 230 having the same length, and the other part is smaller than the whole body spoiler 230 (preferably half of the whole body spoiler). Length, but the other part may be composed of a belly node spoiler 220 having a longer length than the on-body spoiler 230.

In addition, the length unit of the half-body spoiler 210, the full-body spoiler 230, the belly-body spoiler 220 of the knot-type spoiler 230, millimeters (mm), centimeters (cm), inches (inch), etc. Although may be appropriately used, more preferably it is more advantageous to set in an inch unit, which is a commonly used standard when distinguishing the size of the wiper.

When the length unit of the nodular spoilers 230 is set to inches, when the on-body spoiler 230 is 1 inch among the plurality of nodular spoilers 230, the half-body spoiler 210 is the same. It is preferable to use a smaller length of 0.5 inch, and it is preferable to apply the ventral spoiler 220 to 2 inch or 3 inch, which is a larger length.

In this case, when manufacturing a car wiper including a left and right spoiler, when the total length (L) of the wiper is required even length (13 inches, 15 inches, 17 inches, etc.), the ship body spoiler 220 If you assemble using only a plurality of on-body spoiler 230, including, even length can be established naturally,

If the total length L of the wiper is required to be an odd length (13 inches, 15 inches, 17 inches, etc.), after assembling a plurality of on-body spoiler 230 including the belly node spoiler 220, The application of one additional half spoiler 210 (0.5 inch, half) is also very easy as the total length of the wiper is automatically adjusted to an odd number of units.

On the other hand, the articulated coupling means 240, each of the joint shaft 241 protruding to a certain height on the inner surface of the both sides of the nodal spoiler 200, the other nodal spoiler 200 corresponding to this After the connector 243 is further extruded, the joint groove 242 is formed in an intaglio in the connector 243, and the inclined guide portion 241a cut at a predetermined inclination angle to one side of the end of the joint shaft 241. ) To form the joint shaft 241 in the joint groove 242 so that it can be more easily fitted in a straight direction facing each other.

In addition, the connector 243 below the joint groove 242 allows the joint shaft 241 to be guided more easily toward the joint groove 242 when the joint shaft 241 is corresponding, while preventing rotation of the joint excessively. Guide jaw 244 (limiting the rotation range) may be further formed.

When the articulated coupling means 240 is configured as described above, when the joint shaft 241 is pushed in a linear direction facing each other to be fitted into the joint groove 242, the inclined guide part 241a is connected to both sides of the joint shaft 241a. As well as the gap between the joint axis 241 can be easily fitted,

When the joint shaft 241 is moved toward the joint groove 242 due to the guide jaw 244 formed directly below the joint groove 242, even though it is roughly matched, the guide jaw 244 is guided even more easily. Custom assembly is possible.

At this time, the guide jaw 244 is not only guide the joint shaft 241 toward the joint groove 242, but also prevents the degree of rotation is more than necessary during the rotation operation after mutual assembly as much as necessary It is convenient.

In addition, when the individual rocking tongs 250 are configured solely on each bottom of the knuckled spoilers 230 connected to each other, the knuckled spoilers 230 are the upper head of the rubber blade 110. In the state in which the portions 111 are locally gripped, the pressure can be evenly applied in connection with the articulated joint (the rubber blade can be supported by a more uniform pressing force when the rubber blade is in close contact with the curvature of the automobile glass surface). .

In this case, the individual rocking tongs 250 may be gripped at both sides of the upper head 111 of the rubber blade 110 at each lower portion of the knot-shaped spoilers 230 divided into two or more. It is configured to be bent at 90 degrees, such as "b", but it is necessary to configure a single object in the lower portion that corresponds directly to the joint portion 240 is combined.

In addition, the upper and lower spaces of the upper head 111 of the rubber blade 110 is gripped by the respective rocking tongs 250 on the upper side of each individual rocking tongs 250. It is more preferable to further form the rocking limiting portion 245 to limit the degree.

On the other hand, for reference, look at an example of one of the car wiper device for wiping the foreign matter (rain, snow, dust, etc.) on the glass window while turning (rotating) to a certain radius according to the user's operation,

A flexible rubber strip 113 is formed on the lower side to be in direct contact with the curvature of the window, and an upper head 111 is formed on the upper side, and one rail insertion groove 111a is formed on the front and rear sides of the upper head 111. ) Is provided with a rubber blade 110 is engraved,

The rail springs 120 are inserted into the two rail insertion grooves 111a at the upper end of the rubber blade 110, respectively, or inserted into the rail insertion grooves 111a in a state in which the rail springs 120 are embedded or protruded to both sides. The base cover 130 is formed at the center of the upper end of the rubber blade 110,

Both sides of the center base cover 130 are coupled to the left and right spoilers 300 to prevent injury during high-speed driving, respectively.
