The present invention relates to a flat wiper for attaching to a vehicle, and more particularly, the clip is clamped the spring irrespective of whether the spoiler is mounted or not, to prevent shaking up, down, left, and right to separate the springs. Prevents detachment of the wiper strip that is coupled to the space to stably remove debris from the glass surface of the vehicle, and prevents the detachment of the clip due to the impact of centrifugal force during up and down u-turns during the wiper operation. Foreign substances can be removed, and even if the shape of the upper part of the wiper strip changes, the shape of the wiper strip coupling part of the clip or the wiper strip coupling part of the spoiler can be freely changed and used according to the variable length of the product. Detachable string of wiper strip reliably by increasing the number of The prevention and hereinafter as well as, to a decreased elastic force of the clip to form a fixed jaw at the time the upper end, in the vehicle flat wiper capable of preventing deformation by the elastic force.

In general, the vehicle wiper is assembled with a wiper strip made of brackets, springs and rubber connected to the arm and the adapter against foreign substances (rain, snow, dust, etc.) on the windshield of the car and can be wiped clean by turning left and right. The wiper strip is a key component member that plays a role of scraping off the various foreign matters on the windshield while the wiper strip is in direct contact with the front, front, and rear window surface of the vehicle during wiper operation. It is an important factor.

On the other hand, the above-mentioned wiper strip is to remove the foreign matter on the glass surface of the vehicle while forming the curvature by the plate-shaped spring undergoing a heat treatment process to form a constant curvature.

Here, the spring is formed of a single spring as shown in FIG. 1, or a pair of springs forming a constant space as shown in FIG. 2, or form a constant space as shown in FIG. The ends are divided into forms.

That is, the spring having the same structure as in FIG. 1 is configured to combine the spring and the wiper strip with a separate holder when the wiper strip is mounted, whereas the spring having the same structure as in FIGS. The wiper strip can be inserted into the space formed between the springs.

On the other hand, when fixing the wiper strip by using a spring having the structure as described above, as shown in Figure 1, the structure consisting of one spring is made of a structure that is not directly coupled to the wiper strip to the coupling force of the holder for fixing the wiper strip The quality is determined by, but in the case of the spring forming the separation space as shown in Figures 2 to 3, the deformation occurs during the heat treatment process, the coupling process with the bracket, or the process for forming the curvature of the spring, each spring The curvature of is different or a step occurs in the front, rear, left, right, or up and down directions, and the fixing force of the wiper strip is lowered.

The lowering of the fixing force of the wiper strip leads to a decrease in the adhesion between the wiper strip and the vehicle glass surface, and thus acts as a main factor in the vibration of the wiper.

In order to solve this problem, Patent No. 10-0629161 (vehicle wiper blade) as shown in FIGS. 4 to 6 has been proposed.

The registered wiper blade 100 for a vehicle includes a bracket cover 110 for connecting an arm (not shown) of the vehicle and the vehicle wiper blade 100, and a pair of both sides of the bracket cover 110.

On the other hand, it is not a configuration for solving a problem caused by weak coupling force when supporting the wiper strip by using a pair of springs listed above, but having a structurally similar shape (patent wiper blade for vehicle windshield) Has been proposed.

As shown in FIGS. 7 to 8, the windshield wiper blade 200 of the vehicle includes a first holder 236, and spoilers 223 are formed at both sides thereof.

In addition, the second holder 238 is formed on both sides of the spoiler 223, and the spring 232 and the wiper strip 222 is formed at the bottom.

Particularly, in the above-described registered patent, the third holder 240 is further configured after cutting a part of the spoiler 223, so that the spoiler 223 is easily replaced.

In addition, the third holder 240 is configured to surround the spring 232 in the state in which the spring 232 is coupled to the wiper strip 222, and forms a fixing claw 258 at the lower portion of the wiper strip 222. ) And the structure to improve the bonding force.

However, the above conventional technologies have the following problems.

First, in the case of Patent No. 10-0629161, there is a problem in that the manufacturing cost is increased by installing an additional component as well as a complicated structure by forming a separate fixed coupling part 140 to fix the spring 130.

In addition, in order to fix the spring 130 through the fixed coupling portion 140, the clip portion 150 is further formed to clamp more in the upward and downward directions, so that the manufacturing cost increases with the increase of the component and the process Due to the complexity of the productivity has occurred.

Particularly, in the case of the clamp 163 used to fix the spring 130 in the registered patent, there is a problem in that the function is not smoothly detached from the spoiler 160 by the shock generated during the up and down u-turn of the wiper. It is not actually used.

On the other hand, Patent No. 10-0605236 has the advantage of less structural complexity than the prior art described above, by cutting the spoiler 223, the structural stability when the wiper is operated, as well as the spoiler 223 and The first and third holders 236 and 240 have a problem of slipping due to centrifugal force and loss of their function.

In particular, the wiper strip 222 generally uses a rubber made of a soft material to remove foreign substances on the glass surface of the vehicle. In the case of the third holder 240, the wiper strip 222 is directly bonded to the wiper strip 222. The weakness caused a problem of detachment during wiper operation.
