JPH0328055A - Wind shield wiper accommodating device for car - Google Patents

Abstract

PURPOSE:To prevent a wiper blade from running against a wiper cover by driving a pivot for a wind shield wiper, and thereby allowing a driving means to lift the wiper cover from the closed condition. CONSTITUTION:When a wind shield wiper 16 is put in service, a wiper motor is operated to turn a wiper arm 16c through a pivot 16b, and a wiper cover 24 is lifted to the position with a dot and dash line through a rotary lever 24a inserted in a contact recess 16d. As the wiper cover 24 rises in the sequence from the solid line to the dot and dash line and two-dotted chain line, the wiper blade 16a rises synchronously in the sequence as from the solid line to the dot and dash line and the two-dotted chain line, so that the opening of a recess 17 is opened without causing the wiper blade 16a to collide with the wiper cover 24. Thus rattle or secular change of the wiper blade can be suppressed.

Description

[Detailed description of the invention] [Industrial use! P] This invention relates to a front window wiper storage device,
In particular, it relates to a storage device equipped with a drive means for raising the wiper cover by rotation of a pivot shaft. [Prior Art] A conventional device of this kind is, for example, the one shown in FIG. 8 (see Japanese Utility Model Application No. 57-158555). The code 1 in the figure is the engine hood. Code 2 is the front window glass, code 3 is the cowl knob panel,
This cowl lug panel 3 is formed with a recess 3a extending in the vehicle width direction, and a front window wiper 8 is housed within this recess 3a. A pillar 4 is protruded from the recess 3a, and a wiper cover 5 and a link 6, which are integral with each other, are rotatably disposed on the pillar 4. A tension spring 7 is disposed between the wiper force member 5 and the recess 3a, and the tension spring 7 causes the wiper cover 5 and the link 6 to move counterclockwise as shown by the two-dot chain line in the figure. It is energized. When the front window wiper 8 is not in use, the wiper blade 9 wipes the tip 6a of the link 6.
is pressed, the wiper cover 5 is placed in a substantially horizontal state against the urging force of the tension spring 7, and the front window wiper 8 is covered with the wiper cover 5 and stored. On the other hand, in order to use the front window wiper 8,
When the wiper switch is turned on, the wiper blade 9 is rotated and separated from the tip 6a of the link 6.
Due to the biasing force of the tension spring 7, the wiper cover 5
is rotated to open and close as shown by the two-dot chain line in the figure, and the front window glass 2 is wiped. Also, if you turn off the wiper switch while in use,
The distal end 6a of the link 6 is pressed by the wiper blade 9, rotated clockwise against the biasing force of the tension spring 7, and closed by the wiper force per 5. [Case H that Takamei is trying to solve] However, in such conventional devices, when the front window wiper 8 is not in use, an external force is always acting on the wiper blade 9, so the front window If the wiper 8 is rattled or deteriorated, there is a risk that the wiper cover 5 will not be completely closed. [Means for Solving the Problems] The present invention has been made in view of the above-mentioned problems in the prior art, and provides a storage recess in which a front window wiper is stored on the lower edge side of the front window panel in the width direction of the vehicle. A wiper cover is provided in the opening of the wiper storage recess so as to be openable and closable, and the opening is closed with the wiper cover when the front window wiper is not in use. The vehicle front window wiper storage device is provided with a driving means for raising the wiper cover from the closed state by driving the bipot shaft of the front window wiper during one shift of storing the windshield wiper for the vehicle when the windshield wiper is opened in the open state. It is characterized by [Operation] According to this means, when the wiper motor is driven when the front window wiper is used, the pivot shaft rotates. This rotation causes the wiper blade to rise and the wiper cover to simultaneously rise via the drive means. In this way, by using the rotational force of the front window wiper to raise the wiper cover, the movements of the wiper blade and wiper cover can be reliably synchronized, and the wiper blade collides with the wiper force. This can be prevented. In addition, unlike conventional wiper wipers, an external force is not constantly applied to the wiper cover when the wiper cover is open, so it is possible to prevent rattling and deterioration of the front window wiper. [Examples] This invention will be explained below based on Examples. Figures 1 through 8 are diagrams showing a first embodiment of the present invention. First, the structure will be explained. In the figure, reference numeral 11 is an engine hood, reference numeral 12 is a front window glass, and reference numeral 13 is a cowl box. The cowl box 13 is composed of a cowl knob panel 14 and a dash upper panel 15. This cowl top panel 14 costs $1
As shown in the drawings and FIG. 3, a storage recess 17 in which the front window wiper 16 is stored is formed by being recessed along the vehicle width direction. Note that the reference numeral 18a in FIG. 2 is a wiper blade of the front window wiper 16. The wiper cover 24 that opens and closes the opening 17a of the storage recess 17 is connected to the opening/closing device 18.
It can be moved by. This opening/closing device 18
is constructed as shown in Figures 3 to 5.
That is, first, the motor 19 is attached to the cowl top panel 14.
A guide plate 20 extending in the vertical direction is also provided. This guide plate 20 is formed with a vertical slit 20a extending in the vertical direction and a diagonal slit 20b extending obliquely downward from the upper end of the vertical slit 20a in front. A pulley 21 is movably disposed in each of the slits 20a, 20b, and a shaft 22 is inserted through the pulley 21. Further, a first gear 25 is fixed to the rotating shaft 19a of the motor 19, as shown in FIG.
A second gear 26 as a partially toothed gear is meshed with the gear 25. This second gear 26 has a proximal end 23 of the lever 23.
a is fixed, and one end 22a of the shaft 22 is loosely inserted into a long hole 23b formed in this lever 23. This shaft 22 allows the opening 17 of the storage recess 17 to
A wiper cover 24 that opens and closes a is supported. Specifically, the wiper cover 24 has a plate shape, and has a plurality of cover guides 24d projecting downward. The lower end of this cover guide 24d is connected to the shaft 22.
It is fixed to the other end 22b. The wiper cover 24 also has a rotating lever 24 with a predetermined length extending downward.
a is rotatably attached, and this rotary lever 24a is biased clockwise in FIG. 1 by a subring 31. On the other hand, the pivot of the front window wiper 16
As shown in FIG. 1, the wiper arm 16C, which is rotated by the ll16b, has an abutment recess lad formed therein. ) are in contact. This wiper arm 16C
The driving means of this embodiment is composed of the abutting recess lad and the rotating lever 24a. Next, the operation of the automobile front window wiper storage device constructed as described above will be explained. When the wiper is not in use, the front window wiper 16 is stored in the storage recess 17, and the opening 17a of the storage recess 17 is closed with the wiper cover 24. On the other hand, when the front window wiper 16 is used, when a wiper switch (not shown) is turned on, a wiper motor (not shown) is driven to rotate the wiper arm 16c via the bipot shaft 16b. With this, the wiper cover 24 is raised from the state shown by the solid line in FIG. 1 to the state shown by the dashed-dotted line via the rotating lever 24a inserted into the contact recess led.

Wiper cover 24 and wiper blade le in this case
As shown in FIG. 6, as the wiper cover 24 moves up as shown in the solid line, the dashed-dotted line, and the dashed-double-dotted line, the wiper blade 16a synchronously moves up as shown in the solid line, One-dot chain line. Since the upper limit is as shown by the two-dot chain line, the wiper blade 16a is connected to the wiper cover 24.
The opening 17a is opened without any collision. Due to the upper limit of this wiper cover 24, the lever 23
is rotated as shown in Figure 3 from the solid line to the dashed line,
The pulley 21 is the vertical slit 20 of the guide plate 20
The upper bound is along a. In this state, the lever 23 is rotated as shown from the dashed line to the dashed double dot line in FIG. The wiper cover 24 moves downward to the position indicated by the two-dot chain line in the figure and stops. This completes the opening of the opening 17a of the storage recess 17. On the other hand, to retract the front window wiper 16, the motor 19 is rotated in the opposite direction. Then, the lever 23 rotates as shown by the two-dot chain line and the one-dot chain line in FIG. In such a device, since an external force is not constantly applied to the wiper blade lea of the front window wiper 16 when the wiper cover 24 is open as in the conventional case, the front window wiper l6 may become loose or change over time. can be suppressed. Furthermore, when the front window wiper 16 is in use, the wiper cover 24 is stopped in a substantially horizontal state as shown by the two-dot chain line in FIG. Compared to the conventional model, the air resistance during driving is reduced. FIG. 7 shows a second embodiment of the invention. In this embodiment, a driving bevel gear 32 is provided at the upper end of the pivot shaft 18b, and a gas stay 2 is provided at the cowl top panel 14.
7 is disposed, and this gas stay 27 has a bearing portion 27a.
A driven bevel gear 29 that meshes with the driving bevel gear 32 is rotatably disposed on the bearing portion 27a. A slide gear 28 is inserted through the bearing portion 27a and the driven bevel gear 29 in the vertical direction, and the rotation of the driven bevel gear 29 causes the slide gear 28 to move up and down. The upper end 28a of the slide gear 28 comes into contact with an elastic body 30 provided on the wiper cover 24. In this way, when the driving bevel gear 32 rotates due to the rotation of the pivot shaft 18b, the driven bevel gear 29 rotates.
This rotation causes the slide gear 28 to rise, and the slide gear 28 raises the wiper cover 24 from the state shown by the solid line in the figure to the state shown by the dashed-dotted line. and,
As in the previous embodiment, the wiper cover 24 moves from the state shown by the one-dot chain line in the figure to the state shown by the two-dot chain line. In the open state shown by the two-dot chain line in this figure, the elastic body 30 comes into contact with the engine hood 11, so that the engine hood 11 is prevented from being damaged. The other configurations and operations are the same as those in the first embodiment, so their explanation will be omitted. [Effects of the Invention] As described above, according to the present invention, by providing a driving means for raising the wiper cover from the open state by driving the pivot shaft of the front window wiper, the wiper cover can be raised by driving the pivot shaft of the front window wiper. By driving,
Since the wiper blade is raised via a drive means, the movement of the wiper blade and the movement of the wiper cover can be synchronized, preventing the wiper blade from colliding with the wiper cover and preventing the wiper blade from rattling or aging. It has the practical effect of suppressing changes, etc.
