Abstract

PURPOSE:To surely cover a blade with a cover body at the time of housing by providing an elastic element for energizing a housing cover body to an opening or a closing side midway while opening or closing same, and an operating body which is brought into contact with the blade getting in or out of a housing chamber and which operates the cover body to an opening or a closing side. CONSTITUTION:When a cover body 12 is in a posture of being closed or opened, the cover body 12 is energized toward that side by means of an elastic element 13 which acts beyond a fulcrum to maintain the posture in the corresponding condition. When the blade 5 gates out of a case body 11, a bracket 4 is brought into contact with the inner face of the cover body 12 and pushes up same to change the posture thereof to an open side while, on the other hand, at the time of getting into the case body 11, the bracket 4 is brought into contact with an operating body 12c and depresses same to change the posture of the cover body 5 to a closing side. Thus, when wiping is not necessary, the blade 5 is housed in the case body 11 in a condition of being covered with the cover boyd 12. Hence, the opening/closing of the cover body 12 is automatically carried out by means of the getting in/out action of the blade 5 with respect to the case body 11.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a storage device for a wiper blade for wiping a door window surface of a passenger car or the like.

[Problems to be solved by the prior art and the invention today]
Vehicles with side mirrors attached to the doors are mass-produced, but in such vehicles, it may be difficult to see the side mirrors unless the door window surface is wiped off, especially during rainy weather. Therefore, conventionally, JP-A-62-128862 or JP-A-6
A wiper device for wiping a door glass plate is known as shown in Japanese Patent No. 2-163852. However, since the former type is stored with the blade for wiping the glass surface exposed, it has the disadvantage that not only is it inferior in appearance, but also the weather resistance of the blade becomes a problem. On the other hand, in the latter case, the blade is retracted so as to cover it when the machine is stopped, so that it is not exposed.However, in this case, a separate dedicated drive mechanism is installed to open and close the cover that covers the blade. This not only complicates the structure but also requires a dedicated control means to drive these drives in a timely manner, which is a problem.

[Means for solving the problem] In view of the above-mentioned circumstances, the present invention was devised for the purpose of providing a wiper blade storage device that can eliminate these drawbacks. In a wiper device that wipes the outer surface of a glass plate with a blade provided at the tip of a wiper arm that reciprocates, a storage chamber is formed at the upper outside of the door in which the blade is stored when the operation is stopped, and the storage chamber is opened and closed. The lid is equipped with a bullet that moves over a fulcrum during the opening/closing operation and urges the lid toward the opening or closing side, and a blade that connects to the blade that moves in and out of the storage chamber. The present invention is characterized in that it is provided with an actuating body for actuating the lid body to the opening side or the closing side.

With this configuration, the present invention enables the blade for wiping the door window surface to be reliably covered by the lid so that it is not exposed when stored, without the need for a special drive mechanism. be.

[Embodiment 1] Next, an embodiment of the present invention will be explained based on the drawings. In the drawing, 1 is a side wiper device attached to a door 2, and the wiper arm 3 constituting the side wiper device 1 has an arc shape. A blade 5 is attached to the upper end of the blade 5 via a bracket 4 so as to be arranged in the left-right direction.

Reference numeral 6 denotes an arm guide provided on the outer panel 2a side of the door 2, and the arm guide 6 guides the wiper arm 3 up and down. A portion 6a and a pulley 6b around which the portion 6a is wound are provided above and below. The operating wire 7 and wiper arm 3 are integrally connected via a connecting plate 8. In addition, 2c is a glass guide that guides the front edge of the glass plate 2b, 2d is an inner panel of the door, and 2e is an outer panel 2.
The molding provided on the upper edge of a, 2f is a lip material that comes into contact with the glass surface.

9 is a drive motor, and the drive motor 9 is integrally attached to the inner plate 2d side.

A motor shaft (not shown) of the drive motor 9 protrudes forward, and is adapted to rotate a pulley (not shown) inside the pulley case 10 in forward and reverse directions. The actuating wire 7 is wound around the front edge of the actuator 7 from the front side. Then, the drive motor 9 performs a controlled forward and reverse drive in conjunction with turning on a wiper switch (not shown) to reciprocate the actuating wire 7, thereby causing the wiper arm 3 to move up and down, thereby causing the blade 5 to wipe the glass. It is designed to wipe the board surface.

Reference numeral 11 designates a case body that is fitted into a notched portion of the molding 2e and integrally bolted to the reinforcing material 2g of the outer panel 2a, and forms a storage chamber for the blade 5.
The case body 11 is provided with a through hole 11a through which the wiper arm 3 passes.

On the other hand, 12 is a lid body attached to the case body 11, and the leg portion 12a of the lid body 12 extends downwardly through a through hole 11b bored in the case body 11. It is pivotably supported via a support shaft 12b to a support plate lid protruding from the lower surface of the lid, and can swing between an open position and a closed position (mall 2e and road surface state).
An operating body 12c is provided on the inner surface of the lid 12 in a protruding manner, with which the bracket 4 to which the blade 5 is fixed comes into contact from above when the blade 5 is retracted. Reference numeral 13 denotes an ammunition machine interposed between the operating body 12c and the pin shaft 11c provided on the case body 11, and the ammunition machine 13 performs the opening/closing operation when the lid body 12 changes from the closed position to the open position. In the middle, a so-called fulcrum crossing operation beyond the support shaft 12b is performed, and the lid body 12 is biased toward each posture direction. When the blade 5 comes out of the case body 11 and tries to perform the wiping operation,
When the bracket 4 is connected to the inner surface of the lid body 12 (when the inner surface is opened,
(corresponding to the operating body that the blade comes into contact with) and pushes it up against the projectile 13, transforming the lid body 12 into an open position with the projectile 13 passing over the fulcrum, and also wiping it away. When the lid body 12 is stored in the case body 11 upon completion of the operation, the bracket 4 contacts the operating body 12c from above and pushes it down against the ammunition 13, causing the lid body 12 to move over the fulcrum of the ammunition 13. It is designed to transform the body into a closed position. Furthermore, in this case, the wiper arm 3 of the blade 5 housed in the case body 11 moves along the inner edge of the through hole 11a, so that the wiping part 5a on the tip side is separated from the glass surface, and is in a free state without any contact. It is set as follows.

In an embodiment of the invention constructed as described, door 2
The wiping of the glass plate surface is accomplished by the vertical and reciprocating movement of the blade 5 linked to the controlled forward and reverse drive of the drive motor 9, thereby preventing the side mirror from being blocked by water droplets even in rainy weather. It can be seen through the glass plate 2b without any problems.

In this way, in the present invention, the door glass surface can be wiped if necessary, but when the door glass surface does not need to be wiped when the blade 5 is stopped, the blade 5 is in a state where the lid body 12 is closed and not exposed. Then, it is stored in the case body 11. In other words, when the lid body 12 is in the closed or open position, it is urged toward each side by the ammunition 13 that acts while crossing the fulcrum, and the posture is maintained in the corresponding state. However, when the blade 5 comes out from the case body 11, the bracket 4 is attached to the lid body 1.
2. Contact the inner surface and push it up to change it to the open side,
On the other hand, when entering the case body 11, the bracket 4 is
2c and push it down to change it to the closing side.

In this way, in the present invention, when wiping is not required, the blade 5 is covered by the lid 12 when the blade 5 is removed from the case body 12.
Therefore, not only does it not look bad, but it also has improved weather resistance.
The opening and closing of the lid body 12 is automatically accomplished by moving the blade 5 in and out of the case body 11. As a result, the lid body 12 does not require a dedicated opening/closing drive mechanism as in the past, and the movement of the wiper arm 3 into and out of the case body 11 is effectively used to operate the lid body 12 automatically. can be significantly simplified and made lightweight and compact.

Moreover, since the lid body 12 is held in the corresponding posture by the action of the bullet 13 over the fulcrum, the force for maintaining the lid body 12 in that posture when closing is applied to the wiper arm 3. There is no need to take the trouble to secure the blade 5 from the side, so it is possible to maintain the lid body 12 in the closed position by increasing the accuracy of the retracted position of the blade 5, or to secure the blade 5 in the closed position.
There is no need to lock it and hold it in the closed position.
As a result, an even greater simplification of the structure can be achieved.

[Operations and Effects] In summary, since the present invention is configured as described above, the blade is stored in a state where the lid body is in a closed position and is not exposed when unnecessary.
Therefore, it can be made to have excellent weather resistance without damaging the appearance, but when the blade moves in and out of the storage chamber, it comes into contact with the actuating body provided on the lid, which serves as the fulcrum of the ammunition. This will be done automatically when the overstepping operation is performed. As a result, a separate dedicated opening/closing drive mechanism as in the prior art is completely unnecessary, resulting in a significant simplification of the structure.

Moreover, the lid body can be used when the blade is retracted.

The lid is held in the closed position by the biasing force of the projectile that has crossed the fulcrum, so there is no need to obtain force from the wiper device to hold the lid in the closed position, and this reduces the accuracy of the blade storage position. This eliminates the need for consideration such as raising the height to maintain the lid in the closed position.
