Abstract

A device for keeping the blade of a vehicle windscreen wiper clear of the screen when parked comprises a flat bottom fastened to the windscreen by double-sided adhesive tape, a vertical stop wall raised from the flat bottom for stopping the wiper blade during its down stroke, and a guide slope perpendicularly projected from the ridge of the vertical stop wall to engage and guide the yoke upwards in lifting the rubber blade from the windscreen. A sleeve 14 may be fitted to extend the guide surface for fitting different wipers. Two parallel guide surfaces may be provided (Fig 4). <IMAGE>

Description

WIPER RACK FOR RESTING THE WINDSHIELD WIPER OF A CAR The present invention relates to a wiper rack for resting the windshield wiper of a car to keep the wiper blade spaced from the windshield of the car as the windshield wiper does no work.

In recent years, motorcars have become more and more popular everywhere. In order to attract consumers to buy cars, every car maker has been continually trying to make cars more comfortable and safe to drive. A variety of auxiliary devices, such as ABS, air bags, central control door lock systems, automatic car window controls, etc., have been disclosed for this purpose. The quality of the windshield wiper is also an important factor to be taken into account, because the windshield wiper maintains the clarity of vision of the windshield of a car. The windshield wiper is generally comprised of a blade holder frame connected to a mechanism arm attached to the windshield of a car and driven to reciprocate a rubber blade over the windshield in wiping off rain, snow, etc. When the windshield wiper does no work, it is rested on the windshield along the bottom edge thereof. As the rubber blade of the windshield wiper is constantly and closely disposed in contact with the windshield, dust and particles may be accumulated in every corner around the windshield wiper. As the windshield wiper is reciprocated to wipe off rain, snow, etc., the dust and particles may be rubbed against the windshield to damage its clarity.

Because the coefficient of heat conductivity of the windshield is much higher than the rubber blade of the windshield wiper, the rubber blade of the windshield wiper may be heated to deform as the windshield is disposed under the radiation of the sun directly for a length of time. If the rubber blade of the windshield wiper deforms, the wiping effect of the windshield is relatively reduced. Further, the rubber blade of the windshield wiper may be hardened with cold and become tightly adhered to the windshield during the coldest season of the year. If the rubber blade of the windshield wiper is tightly adhered to the windshield, the reciprocating mechanism which reciprocates the windshield wiper may be damaged easily due to an overload.

An object of the present invention is to provide a wiper rack for resting the windshield wiper of a car which eliminates the aforesaid drawbacks.

According to the present invention there is provided a wiper rack comprising a flat bottom arranged to be fastened to the windshield of a car by a double-sided adhesive tape, a vertical stop wall extending outwardly from the flat bottom for stopping the rubber blade of the windshield wiper of the car during its down stroke, and a guide slope projecting perpendicularly from the ridge of the vertical stop wall to guide a holder frame of the windshield wiper upwards in lifting the rubber blade from the windshield.

In one preferred embodiment of the present invention there is provided a wiper rack which is suitable for holding the rubber blade of the windshield wiper above the windshield of any of a variety of cars.

Preferably there is provided a wiper rack which stops the windshield wiper of a car from moving over the predetermined lower limit during its down stroke.

According to another preferred embodiment of the present invention, the wiper rack has a guide slop to guide the blade holder frame of the windshield wiper upwards as the windshield wiper is moved downwards, so that the rubber blade of the windshield wiper is lifted from the windshield as the windshield wiper reaches the lower limit. A vertical stop wall is formed on the wiper rack to stop the windshield wiper from moving downwards.

A guide sleeve may be attached to the guide slope of the wiper rack to extend the length of the guiding surface according to the type of the windshield wiper to be matched.

Embodments of the present invention will now be described by way of example with referençe to the accompanying drawings in which Fig. 1 is a perspective elevational view of a wiper rack according to present invention; Fig. 2 is an installed view showing the wiper rack mounted on the windshield to hold the wider blade of the windshield wiper; Fig. 3 illustrates a guide sleeve mounted around the guide slope of the wiper rack; and Fig. 4 illustrates an alternate form of the wiper rack.

Referring to the various drawings attached herewith, a detailed description of the structural features of " WIPTER RACK FOR RESTING THE WINDSHIELD WIPER OF A CAR " of the present invention is as follows: Referring to Figures 1 and 2, a wiper rack in accordance with the present invention is generally comprised of a rack body 1. The rack body 1 comprises a flat bottom 11 attached with a double-ided adhesive tape 4 for mounting on the windshield 2 of a car, a vertical stop wall 13 raised from the flat bottom 11 at a suitable elevation, and a guide slope 12 perpendicularly projected from the ridge of the vertical stop wall 13 at the top and gradually sloping sideways downwards.

Referring to Figure 2 again, the wiper rack is fastened to the windshield 2 of a car near the bottom edge, with the guide slop 12 disposed against the down stroke direction of the windshield wiper 3. As the windshield wiper 3 is moved downwards toward the wiper rack, the blade holder frame 31 of the windshield wiper 3 is guided upwards by the guide slope 12 to lift the rubber blade 32 from the windshield 2 for allowing the rubber blade 32 to move into the gap between the flat bottom 11 and the guide slope 12 and then to be stopped at the vertical stop wall 12.

Therefore, when the windshield wiper 3 does not work, the blade holder frame 31 is suspended over the guide slope 12, and the rubber blade 32 is rested on the flat bottom 11 and spaced above the windshield 2.

Referring to Figure 3, a guide sleeve 14 may be covered on the guide slope 12 of the rack body 1 to extend the length of the effective guiding surface for fitting different windshield wipers.

Referring to Figure 4, therein illustrated is an alternate form of the present invention which comprises two guide slopes 12;12' for resting the windshield wiper of a bus or big car.

Claims

CLAIMS:

1. A wiper rack comprising a flat bottom arranged to be fastened to the windshield of a car by a double-sided adhesive tape, a vertical stop wall extending outwardly from the flat bottom for stopping the rubber blade of the windshield wiper of the car during its down stroke, and a guide slope projecting perpendicularly from the ridge of the vertical stop wall to guide a holder frame of the windshield wiper upwards in lifting the rubber blade from the windshield.

2. A wiper rack comprising a rack body having a flat bottom attached with a double-sided adhesive tape for mounting on the windshield of a car, at least one vertical stop wall raised from said flat bottom, each vertical stop wall having a ridge, at least one guide slope respectively and perpendicularly projected from the ridge of either vertical stop wall at the top against the down stroke direction of the windshield wiper of the car, the guide slope having a front end made gradually sloping sideways downwards for guiding the holder frame of the windshield wiper upwards in lifting the rubber blade of the windshield wiper from the windshield of the car, during the down stroke of the windshield of the car, for permitting the rubber blade of the windshield wiper to be stopped by said at least one stop wall or rested on said flat bottom.

3. The wiper rack of claim 1 wherein said rack body comprises two guide slopes projected from two vertical stop walls thereof and disposed in parallel with each other.

4. A wiper rack for resting a windshield wiper of a car as hereinbefore described with referenced to, and as illustrated in, Figures 1, 2 and 3, or Figure 4 of the accompanying drawings.
