The present invention not only provides easy / simple and easy engagement / disengagement of the wiper operation arm among the constituent members of the vehicle wiper blade device, but also has various end arm shapes (hook type, side pin type, bayonet type). , Double sided multi-connector that can be fully multi-compatible with a stationary side pin type).

In general, the wiper blades for automobiles mounted on the front and rear windshields of the vehicle to automatically clean dust, other foreign matter, rainwater, and snow on the windshield are easily combined with the operating arm connected to the vehicle body. It is necessary to have a connector (e.g., blade replacement or inspection) that can be separated or separated from each other.

However, since the connector of the conventional wiper blade device has a pin-bonded structure directly to the clamp firmly fixed to the "c" type frame of the wiper blade device or the center of the upper end in the longitudinal direction of the wiper blade body, it is coupled with various operating arms. Not only were there difficulties and inconveniences in separating or dividing, but there were problems such as multi-response to various types of working arms.

That is, when assembling or detaching the hook arm, which is usually hooked to the connector, or when detaching / detaching in the assembled state, a considerable clearance space necessary for the assembly / separation action must be provided at the inlet. When pinned directly to a clamp securely fastened to the center of the longitudinal top of the "c" frame or wiper blade body,

Since no means for preventing the release of the hook arm can be provided at the inlet of the connector, there is no choice but to select a hook arm release preventing means for hand-operating the connector itself or a stopper means using its own elastic force. I didn't

In the case of the conventional locking means of the connector or the stopper means of the locking means to be operated by hand, it is very difficult to operate at the same time in the process of assembling or detaching while holding the wiper blade with one hand and holding the hook arm with the other hand. ,

In the case of the stopper means described above, there is a considerable problem such as the push arm with a very strong force due to its elasticity when assembling or detaching / separating the hook arm. In the case of installing a separate cover considering the compact aesthetics, the need for the clearance space necessary for the assembly / disassembly of the hook arm not only entails significant limitations in the manufacture of the cover but also makes it more difficult to have a more compact and clean appearance. There was also.

On the other hand, the conventional connector has a variety of sizes such as 9 × 3, 9 × 4, 1/4, 3/16 as well as various types of working arms such as hook type, pin type, bayonet type, and stationary pin type. Operating arms and the like have been used, but only a part of the operation of the structure is possible to assemble only a part, there has been a problem such as manufacturing or retaining each of the operating arm type when manufacturing the wiper blade.

Accordingly, the present invention was devised to eliminate the above-mentioned problems. First, one-touch assembly and detachment are very easy and easy without first applying a special operation or a strong force at the time of coupling or detaching the hook arm to the connector of the vehicle wiper blade. In the assembled / combined state, it is possible to maintain a more complete and stable stopper engagement state, and it is naturally granted even if the clearance space necessary for the engagement action is not provided separately when the hook arm is coupled and detached. (Hook type, side pin type, bayonet type, stationary pin type, etc.) was completed as a technical task with the focus on providing a dual rotation type multi-connector that can be fully multi-compatible in one connector.

In order to achieve the above technical problem, the present invention will be described in more detail based on the accompanying drawings.

The present invention is a rotary pin to the rotary pin 21 of the first connector 20 is inserted into the upper end of the clamp 10 provided in the upper center of the longitudinal direction of the vehicle wiper blade device (A) to rotate a certain angle. While forming the engaging groove 11, the opposite end of the locking projection piece that is fixed to the clamp 10 by the operation of the locking adjusting means 22 of the first connector 20 and can be released if necessary ( 12);

Above the clamp 10 is provided with a first connector rotary pin 21 fitted in the rotary pin coupling groove 11 of the clamp 10 in the form of a cover to cover the entire clamp 10 and to cover the entire clamp 10. On the other end of the other end, when the close contact with the engaging projection piece 12 is fixed to the clamp 10, the locking adjustment means 22, which can be easily released when pressed by hand is mounted, both sides of the upper center inside A second connector rotary shaft coupling groove 23 to which the rotary shaft 32 of the second connector 30 is coupled is formed, and a first connector 20 provided with a hook arm stopper 24 is formed inside the distal end portion;

Inside the first connector 20 is coupled to the rotary shaft coupling groove 23 on both sides of the first connector 20, hook arm assembly that can be assembled / coupled by hook-type hook hook hooked around the periphery ( 31 is formed, each of which is equipped with a second connector 30 rotatably rotatable about the rotation shaft 32 protrudes from the center of each of the two sides; It was to include.

The second connector side pin assembly groove through which the pins of the side pin type arm can be inserted and coupled to both rotation shafts of the second connector mounted inwardly of the first connector is formed at both centers of the first connector to which the rotation shaft is in contact. The first connector side pin assembly grooves communicating with the second connector side pin assembly grooves are respectively provided to penetrate each other.

The first connector side pin assembly groove of the first connector and the second connector side pin assembly groove of the second connector may have additional first connector side auxiliary pin assembly grooves having different diameters and second connector side auxiliary pin assembly grooves. Are formed in mutual communication with each other, and the second connector side auxiliary pin assembly groove formed in the second connector has an opening in which a portion of the lower part thereof is opened, thereby positioning the pin in the opening and slightly pressing the second connector. Pressing is engaged, but on the contrary, the force is formed into some open type that can be easily released.

In addition, guide grooves are formed at both centers of both sides of the upper end of the clamp to allow rotation shaft coupling grooves provided at both ends of the inner side of the first connector, and both sides of the guide grooves respectively correspond to the first connector side auxiliary pin assembly grooves. Pin assembly grooves are formed to each have a side pin fastening interlocked with the first connector and the second connector,

On the other hand, the lower side of the hook arm assembly formed on the second connector that can be rotated in the state of being mounted in the upper end of the first connector is formed in two stages of the hook arm support portion 1 and the support portion 2 of different heights, respectively, The other two or more hook arms are also configured for easy assembly.

In addition, at the rear end of the hook arm assembly of the second connector, a straight bayonet-type arm assembly groove is formed, the lower side of which is provided with an elastic piece cut at both sides, and a groove is formed at the upper end of the operating arm. Bayonet-type arms can also be easily assembled and responded to as needed.

In addition, the locking adjustment means 22 is cut on both sides and provided with a pressing piece 22a having a certain elasticity, the other side of the pressing piece 22a is caught or released according to the pressing operation of the pressing piece 22a. A locking operation period 22b having a locking jaw 22c is formed.

As described above, when the dual rotation type multi-connector of the vehicle wiper blade of the present invention is configured to press and release the locking adjusting means of the first connector, the first connector mounted on the clamp is provided with the rotation pin coupling groove of the clamp. The center can rotate at a certain angle,

As the second connector mounted inside the first connector is also rotated in a dual manner entirely different from the existing connector, such as a bidirectional constant angle rotation operation,

In particular, when the hook-arm fastening / assembling or detaching the hook-type hook arm, the distal end of the assembly part of the second connector having the hook arm assembly is exposed to the outside by the stepwise double rotation operation of the first connector and the second connector. Even if you do not provide a clearance space according to hook arm assembly, it is very easy and easy to assemble,

Rotating the first connector to its original position in the state of assembling the hook arm in the assembly portion of the second connector and fastening it to the clamp causes the second connector mounted on the first connector to be locked horizontally with the first connector. In this case, as the hook arm stopper formed on the first connector is automatically positioned at the front end of the hook arm assembly of the second connector, a stopper function may be automatically given, of course, automatically when the first connector is opened. Since the stopper function can also be automatically released, there is no need to provide a separate hook arm locking means to the connector as in the past.

Furthermore, due to the independent rotation or dual rotation function of each of the first connector and the second connector, the first pin and the second connector are provided inside the first connector unlike the conventional one which was separated and then separately separated when assembling / mounting the arm. There is a significant advantage to not having to remove the 2 connector.

In addition, the dual rotation operation of the connector helps to realize a more compact and clean appearance when manufacturing the first connector having a function of the exterior cover.

Further, the dual rotationally operated multi-connector of the present invention has a side male pin type, a female pin type, a bayonet type in addition to the general hook arm as well as the hook arm as described above. It can be called a multi-purpose multi-connector that can selectively assemble various operating arms such as a stationary side pin type, and has considerable practicality without having to manufacture a separate connector according to the type and size of the working arm when manufacturing the connector. Invention.

Dual-rotation type multi-connector of the wiper blade for a vehicle of the present invention as described above, in particular, the first connector and the second connector can be rotated separately, as well as the multi-stage two-stage rotation operation as necessary to operate The invention is not only very easy and simple, it is incomparable to the existing one when assembling or dismounting the arm, but also provides the advantage of selectively assembling / responding to a variety of working arms of various types and sizes. to be.
