Description:
TECHNICAL FIELD 
       [0001]    The present invention relates to an attachable/detachable sun visor facilitating a partial coupling, and more particularly to a sun visor which can be easily attached to/detached from a vehiclewindow, and which enables partial coupling between the sun visor components such that components of a desired usage can be coupled and used as needed. 
       BACKGROUND 
       [0002]    A sun visor for a vehicle, in general, is shaped to match with the configuration of an external upper side of a door of a vehicle and is fixedly attached to the external upper side of the door in such a way to use an adhesive, for example, a double-sided tape disposed on the backside of the sun visor, thus forming a shade protecting a vehicle driver from the direct light from the sun, which consequently is able to provide the vehicle driver with convenience when driving, while preventing the input of rainwater into the vehicle. 
         [0003]    The conventional vehicle sun visor, however, has a problem in the way that it cannot be easily separated from the door of the vehicle after the sun visor has been attached to the door of the vehicle, for which the left and right visual fields of the driver may be disturbed, and the removal of such a conventional sun visor is not easy when it needs to, and an exchange and a repair are not also easy if the sun visor has been broken. 
         [0004]    Meanwhile, while driving a vehicle, it might need to circular the air inside of the vehicle, if necessary, or input external air into the inside of the vehicle so as to prevent any fogging on the window. In the conventional, the door window should be opened or a separate heater or air conditioner should be operated. 
         [0005]    In order to improve the aforementioned inconvenience, the Korean utility model registration number 20-0299065 (a sun visor for a vehicle; hereinafter, it is referred to the prior art 1) describes a sun visor for a vehicle which can be easily attached to or detached from the window of the vehicle, wherein the indoor air can be effectively ventilated while efficiently preventing the input of rainwater into the inside of the vehicle, and since it can be easily attached to or detached from the door of the vehicle, so the sun visor can be detachably attached to the door of the vehicle. Moreover, the sun visor is manufactured in the same shape as the upper side of the vehicle door and is attached to the door, thus preventing any input of rainwater into the inside of the vehicle. This sun visor for a vehicle includes a plate-shaped body which has the same shape as the upper side of the vehicle door and has a concave groove which is formed at its lower portion and into which the top of the window is inserted, wherein the top of the plate-shaped body is inserted into a window concave groove of the vehicle door; and a sun visor plate which is disposed extending with a predetermined curve from one side of the outer surface of the body to an outward direction, wherein a ventilation unit is provided at a portion of the body at the inner side of the sun visor plate in order for the indoor air to be ventilated. 
         [0006]    The Korean utility model publication number 1998-020645 (an attachable and detachable type side sun visor; hereinafter it is referred to a prior art 2) is directed to an attachable and detachable sun visor for a vehicle, which includes an integral support member formed of a fixing part formed to be inserted along a weather strip of an upper side, and a guide groove formed for the upper side of the side glass to be inserted therein; a plurality of ventilation ports formed inside of the support member; a plurality of fins which are installed above and below in the center of a plurality of the ventilation ports; a plurality of ventilation fans formed about a plurality of the fins operating as an axis; and a cover which is formed at an outer side surface from the upper portion of the support member, thus preventing rainwater from entering the inside of the vehicle. 
         [0007]    The aforementioned prior arts 1 and 2, however, have the configuration and shape which may allow the indoor air to be ventilated, but it is hard to effectively prevent the rainwater from entering the inside of the vehicle. 
         [0008]    Moreover, the above prior art technologies may have a limit in setting the height of the window. Since an additional component is not provided except for the sun visor, it is hard to add a separate configuration when the user wants to. 
         [0009]    Furthermore, the above prior art technologies are not equipped with any function to prevent the attachable and detachable sun visor from randomly separating, falling and being broken during the driving of the vehicle in a state where the sun visor has been attached, wherein the aforementioned functions can be implemented in the present invention. In case of the conventional attachable sun visor, since the attachment is implemented using only an adhesive, the adhered portions may become weakened due to a temperature difference between seasons and may be separated, thus being frequently broken. In case of the exchange and attachment and detachment, a predetermined residue, which is hard to remove, may remain.
