Technical Field

The present invention relates, in general, to a washing device used for washing cars or the windows of buildings and, more particularly, to a structural improvement in such a device for simply and quickly washing the cars or the windows using a small quantity of water with a dry hand by forming a water container in the brush-attached washing head of the device and by providing an openable cap on the head.

Background Art

A car may be manually washed with a wet sponge or dustcloth while repeatedly washing and rinsing the sponge or dustcloth in water. However, the sponge or dustcloth in the above case may be laden with micro particles such as sands or soil, thus scratching the glossy surface of the car and thereby causing the glossy surface to lose luster and to be much scratched with the particles while washing the car. In an effort to overcome the above problems, an automatic car washing device used for washing and wiping a car is proposed and used. However, the typical automatic car washing device is problematic in that the device wastes water because the water has to be pressurized by a motored pump and is fed to the brush of the washing device. Another problem of the above automatic car washing device resides in that the device is expensive and has a complex construction, being likely to break down. In this regard, the automatic car washing device fails to come into wide use.

It is, therefore, an object of the present invention to provide a washing device in which the above problems can be overcome and which has a water container formed in the brush-attached washing head of the device and an openable cap provided on the hollow head and selectively opened by an actuating rod, with the actuating rod being selectively pushed in order to open the cap prior to filling water in the container and with the brush-attached bottom wall of the head being perforated in order to discharge water from the container to the brush, thus simply and quickly washing the cars or the windows of buildings using small quantity of water with a dry hand.

In order to accomplish the above object, the present invention provides a washing device comprising a washing head, wherein the washing head is hollowed in order to form a water container and is provided with a brush on a bottom wall thereof, the bottom wall being perforated and forming a plurality of holes thus causing water to be discharged from the water container to the brush while washing.

In the above washing device, an openable cap is provided on the washing head for selectively opening the water container. A spring-biased actuating rod is provided on the head and is coupled to the cap thus selectively opening the cap. A handle coupler is provided on the washing head and couples a handle to the head. The washing device also includes a means for detachably attaching a wiper to the head.

Best Mode for Carrying Out the Invention

Fig. 1 is a perspective view showing the construction and configuration of a washing device according to the primary embodiment of the present invention. Figs. 2A and 2B are sectional views of the washing device of Fig. 1 and show the operation of a cap actuating means of the device. As shown in the drawings, the washing head 1 of the washing device is hollowed thus forming a water container 2. A brush 3 is attached to the bottom wall of the hollow head 1. The brush-attached bottom wall of the washing head 1 is also perforated and thereby has a plurality of holes 4. Due to the above holes 4, water is discharged from the container 2 to the exterior of the head 1 and flows along the brush 3 while washing a car or the windows of a building. An openable cap 6 is hinged to the top edge of the hollow head 1 as best seen in Figs. 2A and 2B.

The openable cap 6 is linked to an actuating rod 7, so that the cap 6 can be selectively opened by the actuating rod 7 prior to filling water in the container 2. The above actuating rod 7 transversely passes through the upper section of the hollow head 1, with both ends of the rod 7 projecting from the front and back walls of the head 1 respectively. The cap 6 is coupled to the actuating rod 7 through a link 8 which is biased by a spring means 9. In the embodiment of Figs. 2A and 2B, a compression coil spring is used as the spring means 9. The back wall of the hollow head 1 has an outer-threaded coupler 10 on its center. The coupler 10 couples a longitudinal handle to the head 1. Provided on the top wall of the hollow head 1 is a wiper fitting means 12 which detachably attaches a longitudinal wiper 11 to the top of the head 1. In the primary embodiment, the wiper fitting means 12 comprises two fitting protrusions which are provided on both sides of the top wall of the head 1.

In Figs. 2A and 2B, the reference numeral 15 denotes the handle which is coupled to the handle coupler 10 provided on the back wall of the head 1.

The operational effect of the above washing device will be described hereinbelow.

The above washing device may be effectively used for washing cars or the windows of a building. In the following description, the washing device of this invention is used for washing a car as an example.

In order to wash a car with the above washing device, the handle 15 is coupled to the protrusion 10 of the empty head 1. Thereafter, the head 1 with the handle 15 is immersed in water filling in a basket (not shown), with the projecting front end of the actuating rod 7 being brought into contact with the inner bottom of the basket.

The head 1 in the above state is pushed downward by pushing the handle 15, so that the actuating rod 7 moves backward as shown in Fig. 2A while compressing the compression coil spring 9 and opening the cap 6. Therefore, the empty container 2 of the head 1 is filled with water. When the head 1 along with the actuating rod 7 is released from the pushing force, the actuating rod 7 elastically returns to its original position due to the restoring force of the compression coil spring 9 as shown in Fig. 2B, thus automatically closing the cap 6. Thereafter, a car is washed with the above washing device. While washing the car with the above device, water discharges from the container 2 to the brush 3 through the holes 4 of the brush-attached bottom wall of the head 1 and washes the glossy surface of the car. In this case, the head 1 smoothly brushes the glossy surface of the car with the soft brush 3 and flushes dust of the car with water thus preventing micro particles such as sands or soil from scratching the glossy surface of the car. Therefore, the washing device of this invention is free from causing the glossy surface of the car to lose luster and to be much scratched with the particles while being washed. After washing the car, the wet glossy surface of the car is wiped by the wiper 11. Fig. 3 is a perspective view showing the construction and configuration of a washing device according to the second embodiment of the present invention. In the second embodiment, two circular caps 6, each of which is provided with a sealing means, are provided on the back wall of the hollow head 1 and are selectively opened by respective spring-biased actuating rods. The actuating rods are perpendicularly fixed to the centers of the respective caps 6 and normally project from the front wall of the

head 1 The wiper fitting means 12 comprises a fitting protrusion which is provided on the center of the top wall of the head 1. In order to fill water in the container 2 of the hollow head 1, the empty head 1 is immersed in water filling in a basket, with the projecting ends of the actuating rods being brought into contact with the inner bottom of the basket. The head 1 in the above state is biased downward by pushing the handle 15, so that the actuating rods move backward while opening the caps 6. Therefore, water is introduced into the container 2 of the head 1 through the opened caps 6

In the washing device, a water discharging control means may be provided on the brush-attached bottom wall of the hollow head 1 thus controlling the quantity of water discharged from the container 2 through the holes 4 of the head 1. In addition, the brush 3 of the head 1 may be substituted with a sponge without affecting the functioning of the present invention.
