(54) WIPER SYSTEM FOR THE TAILGATE GLASS OF A HATCHBACK TYPE VEHICLE
(71) We, TOYOTA JIDOSHA KOGYO KABUSHIKI KAISHA, a Corporation organized under the laws of Japan, of 1, Toyotacho,
Toyota, Aichi, Japan, do hereby declare the invention for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement:
This invention relates to wiper systems and more particularly relates to wiper systems which are applied to the tailgate glass of hatchback type doors for motor vehicles.
In recent years, tailgate glass wiper systems have begun to be installed in automobiles equipped with hatchback type rear doors. Due to structural considerations, however, these wiper systems have been built into the frame of the rear door. Building the wiper system into the frame portion of the rear door has resulted in an increase in the weight of the door. Accordingly it has been necessary to increase the strength and rigidity of door hinges. Increasing the rigidity of the door hinges has resulted in several drawbacks. The first drawback is a further increase in the weight of the door. The second drawback is the necessity that a substantial amount of strength is required to open and close the door.
Accordingly, it is a general object of the pre- sent invention to provide a wiper system for the tailgate class of hatchback type doors for motor vehicles which minimises the weight increase of the rear door.
Another object of the present invention is to provide a wiper system for the tailgate glass of hatchback type rear doors for motor vehicles which is relatively simple and.low in cost.
According to the present invention, there is provided a wiper system for the tailgate glass of a motor vehicle, comprising driving means mounted on the vehicle body adjacent the tailgate and driven means mounted on the tailgate and connected to a wiper arm; wherein the driving means includes a driving coupling plate, and the driven means includes a driven coupling plate rotatable with a wiper arm shaft mounted for unrestricted pivotal movement within the wiping arc when the tailgate is open; a plurality of dogs on one coupling plate, and a like plurality of apertures on the other coupling plate, said dogs and apertures being disposed such that on closing the tailgate, if the dogs and apertures are not mutually engaged, operation of the driving means causes relative rotational motion between the coupling plates and brings each dog into axial alingment with a respective aperture, and means are provided thereafter to urge the coupling plates together to enter each dog into its respective aperture and so couple the driving and driven coupling plates in the desired rotational relationship for wiping of the glass. In a preferred embodiment of the invention, the wiping arc subtends at the centre of rotation of the wiper arm shaft an overall included angle 0, and the dogs and apertures of the coupling plates are arranged in equispaced array around the axis of rotation of the plates, the number of dogs (n) being less than 360" divided by 0.
In order that the invention may be more fully understood, embodiments in accordance therewith will now be described by way of example, with reference to the accompanying drawings, in which:
Figure 1 is a perspective view of the rear end of a motor vehicle which is equipped with a wiper system for the tailgate glass of the rear door;

Figure 7 is a cross-sectional view illustrating the clutch portion of a further embodiment;
Figure 8 is a cross-section illustrating a modification of the oscillating drive mechanism of
Figure 4;
Figure 9 is a perspective view illustrating another embodiment of a clutch mechanism for a wiper system;
Figure 10 is a cross-sectional view illustrating part of a further embodiment of a wiper system.
Referring more particularly to the drawings, as shown in Figure 1 there is illustrated the rear of a motor vehicle 2 which is equipped with a wiper system 1 in accordance with the teachings of the present invention. As shown in Figure 1, the wiper arm 6 of the wiper system 1 is supported so that it is free to pivot on pivot shaft 7 in the lower central portion of the door frame 5 which supports the tailgate glass 4 in the hatchback type rear gate door 3 of motor vehicle 2.
A wiper arm stopper (not shown) can be provided on the outside of door 3.
Referring to Figure 2, this shows the particular form of one embodiment of a wiper system for a rear door of a motor vehicle. As shown in Figure 2 a wiper arm pivot shaft 7 is supported in the door frame 5 by means of a bearing 8. Furthermore, a male coupling plate 110 is integrally and coaxially mounted on the end of the pivot shaft 7 which projects into the interior 9 of the automobile. Dogs in the form of pegs 111 are provided at fixed angular intervals on the surface of the male coupling 110.
When the open door 3 (as shown in Figure 2) is closed (as shown in Figure 3) the dogs 111 fit into insertion holes 114 of a female coupling plate 113 provided in the body 11 of the motor vehicle and the male coupling plate 110 and female coupling plate 113 rigidly interlock with regard to the direction of rotation.
The female coupling plate 113 is provided so that it is free to rotate on a shaft 116 fastened to a housing 115 attached to the inside of the body 11 of the motor vehicle. Furthermore, the female coupling plate 113 is mounted so that it is free to slide in an axial direction on shaft 116 and is biassed towards the outside (towards male coupling plate 110) by spring 117.
Gear teeth 118 are formed around the circumference of the female coupling plate 113. The gear teeth 118 engage with oscillating gear 119 as shown in Figure 4. The oscillating gear 119 is coupled to a worm wheel 121 via a crank rod 120. The radius of gyration of the point of connection between the crank rod 120 and the worm wheel 121 is smaller than the radius of gyration of the point of connection between the crank rod 120 and the oscillating gear 118.
Accordingly, the oscillating gear 119 oscillates as the worm wheel 121 revolves. The worm wheel 121 engages with a worm gear 124 coupled to shaft 123 of motor 122. Accordingly the worm wheel 121 is driven at a reduced rate by the motor 122. Furthermore, the worm wheel 121 is mounted on a support shaft 121A.
Furthermore, the dogs 111 on the male coupling plate 110 and the insertion holes 114 in the female coupling plate 113 are provided at certain fixed annular intervals (as shown in
Figure 9) such that the coupling takes place in only one given angular position. If the insertion holes are installed at equal angualr intervals, it is necessary to limit "n" the number of holes such that "n" is less than 360" divided by 0, where 0 is the overall angle of operation of the wiper arm. This condition is necessary in order to ensure that the dogs will not slip into improper insertion holes regardless of where the wiper arm may stop within its overall angle of operation. However, if installation is made at non-uniform intervals, n is not limited by the inequality given above.
In operation, when the door 3 is closed, the dogs 111 on the male coupling plate 110 first contact the female coupling plate 113. If the dogs 111 and the insertion holes 114 are in coincidence, the dogs 111 will immediately slip into insertion 114. If the plates are out of position, however, the female coupling plate 113 is pressed against the spring 117 by the dogs 111 and is pushed into the position indicated by the broken line 113A in Figure 2.
When the motor 122 is then run under these conditions, the worm gear 124 and the worm wheel 121 revolves. The oscillating gear 119 connected to the worm wheel 21 via crank rod 20 begins its oscillating motion. When the oscillating gear 119 oscillates, female coupling plate 113 which is connected to the oscillating gear 119 via the gear tooth 118 also oscillates.
When the plate 113 has rotated into the proper position, the insertion holes 114 and the female coupling plate 113 slip down over the dogs 111 on the male coupling plate 110.
Therefore, the female coupling plate 113 will return to the position shown in Figure 3 by the spring 117.
Therefore even if the wiper arm 6 moves while the door 3 is open so that the dogs 111 are moved into a position in which they will not slip into the insertion holes 114, the coupling plates 110 and 113 are easily coupled by means of their clutch action. Thus, the wiper 6 can be caused to oscillate regardless of its initial position. Furthermore, shock created by closing door 3 can be absorbed by the spring 117.
Referring to Figure 6 shown therein is a second embodiment of a clutch assembly for a wiper system in accordance with the teachings of the present invention. In this embodiment, the transmission of oscillating motion to the pivot shaft 7 is accomplished by means of a cone clutch. Specifically, a cone 130 with a convergent taper is integrally and coaxially provided on the end of pivot shaft 7. A tapered hole 131 which fits over the cone 130 is formed in the female coupling plate 113. Furthermore, dosg 132 are provided around the outside of cone 130 and insertion holes 133 are provided around the outside of tapered hole 131 in the surface which faces the cone 130.
In this embodiment, the dogs 132 and the insertion holes 133 regulate the position of engage ment between the pivot shaft 7 and the female coupling plate 113. The transmission of the oscillating motion is accomplished by means of the coupling between the cone 130 and the tapered hole 131.
Referring to Figure 7, shown therein is a third embodiment of a clutch assembly for the wiper system in accordance with the teachings of the present invention. In this embodiment, the coupling between the male coupling plate 110 and the female coupling plate 113 is accomplished by means of electromagnetic force.
Specifically, the male plate 110 consists of a magnetic body and an electromagnetic coil 135 is provided in the coupling plate 113. The electromagnetic coil 135 is electrically connected with the driving switch (not shown in Figure 7) of the motor 122 and is supplied with current from the power source circuit (not shown in
Figure 7) which is switched on and off. Furthermore the male coupling plate 110 is provided with dogs 136 and the female coupling plate 113 is provoded with insertion holes 137. In addition, a power cord 138 electrically couples the electromagnetic coil 136 to the power source and the cord 138 designed such that it can withstand the oscillating motion of the female coupling plate 113.
In operation, the electromagnetic coil 135 is magentised by the flow of current through it when the motor 122 is driven. The magnetisation of the electromagnetic coil 135 causes the male coupling plate 110 to be drawn into the female coupling plate 113 so that the oscillating motion of the female coupling plate 113 can be transmitted to the male coupling plate 110.
In this embodiment, the positioning of the female coupling plate 113 and the male coupling plate 110 is accomplished by engagement of the dogs 136 with the insertion holes 137.
Even though the above embodiment of
Figure 7 is described in terms of an electromagnetic coil 135 it would also be possible to use a permanent magnet'instead of the electromagnetic coil 135.
In each of the above described embodiments, the rotary motion of the motor 122 is converted into oscillating motion by means of a crank 120 provided between a worm wheel 121 and an oscillating gear 119. This oscillating motion is transmitted to the female coupling plate 113. However, it would also be possible to effect this conversion into oscillating motion by connecting the worm wheel 121 to the female coupling plate 113 by means of a crank rod 139 as shown in Figure 8. In this case, it is desirable that the angle of operation of the male coupling plate 110 and the integrally attached pivot shaft 7 in wiper arm 6 be 1800 of less in order to prevent the male coupling plate 110 from interfering with the crank rod 139.
In each of the above described embodiments, male coupling plate 110 and female coupling plate 113 have been designed so that either positioning alone or positioning in the transmission of power are accomplished by means of dogs and insertion holes provided on the facing side of the two plates. However, it would also be possible to design the male coupling plate 110 and female coupling plate 113 such that dogs 140 are provided around the circumference of the male coupling plate 110 and such that the insertion holes 141 which would engage with the male coupling plate 110 in a given position are provided in the opposing surface of the female coupling plate as shown in Figure 9. In such a case, the dogs 140 would be highly resistant to abrasion, etc. Furthermore, in most of the above described embodiments, the pivot shaft of the wiper arm is provided in the frame portion of the rear gate door. However, in the case of sports cars, light automobiles, etc., which have a frameless rear gate door consisting entirely of glass or a sheet of plastic, it would also be possible to support the bearing 8 of the pivot shaft 7 by means of a rubber bushing 142 as shown in
Figure 10.
As is apparent from the above description, since only the wiper arm and a coupling are provided on the rear door, the windshield wiper system possesses superior characteristics in that the portion of the wiper mechanism placed on the rear door is small and lightweight and therefore minimises the weight increase to the rear door. In addition, such a wiper mechanism can be installed in glass frameless rear doors.
It should be apparent to one skilled in the art that the above described embodiments are merely illustrative of but a few of the many possible specific embodiments which can represent the applications of the principles of the present invention. Numerous and varied other arrangements can be readily devised by those skilled in the art without departing from the scope of the preenst invention, as defined in the appended claims.
