     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Hereinafter, an explanation on goggles with lens protection film according to preferred embodiments of the present invention will be in detail given with reference to the attached drawings. 
     According to the present invention, as shown in  FIGS. 1 to 10 , goggles with lens protection film include film  100  adapted to cover the front surfaces of lenses  10 , a film supply part  200  adapted to unroll the film  100  toward the front of the lenses  10  in a state of winding the film  100  thereinto; a film return part  300  adapted to roll the film  100  unrolled to the front of the lenses thereinto; a drive part  400  adapted to generate power to automatically roll the film  100 ; and a manipulating part  500  adapted to remotely control an operation of the drive part  400 . 
     The film  100  is made of a transparent material so as to provide a clear view in the state of covering the front surfaces of the lenses  10  and has an elongated belt-like shape so as to be rolled. For example, the film  100  is made of a transparent synthetic resin and has a width in a range between 5 cm and 10 cm so as to provide a clean view. 
     The film supply part  200  is coupled to one side of the goggles and serves to unroll the film  100  toward the front of the lenses  10  in the state of winding the film  100  thereinto. The film supply part  200  may be coupled for example to one lens  10  or a frame  20  for goggles. 
     As shown in  FIGS. 2 and 3 , the film supply part  200  includes a case  210 , a winding roll  220 , and a one-way clutch  230 . The case  210  is coupled to one side of the goggles and has entrance and exit formed in an opposite direction thereto. The entrance and exit of the case  210  is formed near one side lens  10  such that the film  100  is unrolled at a state of being brought into close contact with one side lens  10 . The winding roll  220  is disposed inside the case  210  and is rotated forwardly to roll or unroll the film  100  thereonto or therefrom. The one-way clutch  230  serves to allow the winding roll  210  to be gently rotated forwardly to unroll the film  100  therefrom, while preventing the winding roll  210  from being rotated reversely to roll the film  100  thereonto. 
     The one-way clutch  230  is composed of a latch gear  231  disposed at the inside of the case  210  and an elastic latch  232  adapted to be coupled to the winding roll  220 . The elastic latch  232  is locked to the latch gear  231  when the winding roll  220  is rotated forwardly, and contrarily, it is unlocked from the latch gear  231  when the winding roll  220  is rotated reversely. For example, the configuration is the same as that in  FIGS. 5 and 6 . 
     The film return part  300  is coupled to the other side of the goggles and serves to roll the film  100  unrolled toward the front of the lenses  10  thereinto. The film return part  300  may be coupled for example to one lens  10  or the frame  20  for goggles. 
     As shown in  FIGS. 2 and 4 , the film return part  300  includes a case  310 , a winding roll  320 , and a one-way clutch  330 . The case  310  is coupled to the other side of the goggles and has entrance and exit formed at an opposite direction thereto. The entrance and exit of the case  310  is formed near one side lens  10  such that the film  100  is rolled in a state of being brought into close contact with one side lens  10 . The winding roll  320  is disposed inside the case  310  and is rotated forwardly to roll or unroll the film  100  thereonto or therefrom. The one-way clutch  330  serves to allow the winding roll  310  to be gently rotated forwardly to roll the film  100  thereonto, while preventing the winding roll  310  from being rotated reversely to unroll the film  100  therefrom. 
     As shown in  FIGS. 5 and 6 , the one-way clutch  330  is composed of a latch gear  331  disposed at the inside of the case  310  and an elastic latch  332  adapted to be coupled to the winding roll  320 . The elastic latch  332  is locked to the latch gear  331  when the winding roll  220  is rotated forwardly, and contrarily, it is unlocked from the latch gear  331  when the winding roll  320  is rotated reversely. 
     As mentioned above, the film supply part  200  serves to unroll the film  100  in the state of initially winding the film  100  thereinto, and the film return part  300  serves to roll the film  100  being unrolled in the state where the film  100  is not initially rolled thereinto. Accordingly, the film supply part  200  and the film return part  300  have a generally symmetrical configuration to each other. 
     The drive part  400  is adapted to be coupled to the film return part  300  and serves to generate power to automatically wind the film  100 . The drive part  400  has a motor  410  adapted to rotate the film return part  300  so as to automatically wind the film  100 , and therefore, the film  100  is wound not manually, but by means of the rotation of the film return part  300  through the motor  410 . 
     The manipulating part  500  is connected to the drive part  400  with wire or without wire and serves to remotely control the operation of the drive part  400 . The manipulating part  500  is connected to the drive part  400  with wire or without wire, and on the other hand, it is mounted on a hand grip of a stick if a wearer skies and on a steering wheel if he rides a bike, which enables the manipulation with his fingers, without separating his hand from the stick or the steering wheel. 
     The configuration where the drive part  400  is connected to the manipulating part  500  without wire will be explained below. 
     As shown in  FIGS. 4 and 6 , the drive part  400  has the motor  410  coupled to the winding roll  320  and a receiver module  420  adapted to receive a wireless signal and to operate the motor  410 , and as shown in  FIGS. 1 and 7 , the manipulating part  500  has a switch  510  adapted to control the activation of the drive part  400  and a transmitter module  520  adapted to transmit the wireless signal in accordance with the manipulation of the switch  510 . The drive part  400  includes a battery for actuating the motor  410  and for operating the receiver module  420 , and the manipulating part  400  also includes a battery for operating the transmitter module  520 . 
     Accordingly, if lots of foreign materials stick to the film  100  to cause the wearer&#39;s view to be obstructed, the switch  510  of the manipulating part  500  is pressed to transmit a signal through the transmitter module  520 , and thus, the receiver module  410  of the drive part  400  receives the signal to rotate the motor  410 . At this time, if the switch  510  is kept at the pressed state, the signal is kept by means of the transmitter module  520  and the receiver module  420  such that the motor  410  is continuously rotated during that time. 
     Since the drive part  400  and the manipulating part  500  are connected electrically to each other, malfunctions may occur thereon, and also, they may be not operated by the low charge of their batteries. To prevent such problems, as shown in  FIG. 8 , the goggles according to the present invention further includes an auxiliary part  600  adapted to be coupled to the film return part  300  so as to roll the film  100  in a manually operated manner. 
     As shown in  FIGS. 9 and 11 , the auxiliary part  600  includes a reel  610 , a spring  620 , a pulling string  630 , and a one-way clutch  640 . 
     The reel  610  is shaft-coupled coaxially to the winding roll  320  of the film return part  300 . That is, the reel  610  is shaft-coupled at the inside of the case  310  so as to be rotated separately from the winding roll  320 . 
     The spring  620  is disposed inside the reel  610  and serves to rotate the reel  610  forwardly and reversely by means of its own elastic force. That is, the spring  620  is wound to increase the elastic force while the reel  610  is rotated forwardly to roll the film  100 , and contrarily, after the film  100  is rolled, the reel  610  is rotated reversely by means of the elastic force of the spring  620  such that the spring  620  is returned to its original shape. 
     The pulling string  630  is adapted to be wound along the outer periphery of the reel  610  and has a hand grip disposed at the end thereof. That is, if the pulling string  630  is forcedly pulled in the state of being wound on the reel  610 , the reel  610  is rotated forwardly to compress the spring  620 , and contrarily, if pulling of the pulling string  630  is released, the spring  620  is returned and wound on the reel  610 . 
     The one-way clutch  640  is disposed between the reel  610  and the winding roll  320  of the film return part  300  and serves to rotate the winding roll  320  in one direction. 
     The one-way clutch  640  includes a latch gear  641  disposed along the inner surface of the upper periphery of the winding roll  320  and an elastic latch  642  adapted to be coupled to the reel  610  in such a manner as to be locked to the latch gear  641  when the reel  610  is rotated forwardly and contrarily to be unlocked from the latch gear  641  when the reel  610  is rotated reversely. 
     As set forth in the foregoing, there are provided the goggles with the lens protection film wherein while the film covering the front surfaces of the lenses is rolled to one side of the goggles, the foreign materials sticking to the surfaces of the lenses are removed to allow the wearer&#39;s view to be clearly ensured. 
     According to the present invention, further, the film is automatically wound by means of the drive part remotely controlled by the manipulating part, thereby allowing the foreign materials on the lenses to be removed safely and simply. 
     Additionally, the auxiliary part is provided to wind the film in a manually operated manner, such that when the drive part does not work, it is rapidly replaced with the auxiliary part. 
     While the present invention has been described with reference to the particular illustrative embodiments, it is not to be restricted by the embodiments but only by the appended claims. It is to be appreciated that those skilled in the art can change or modify the embodiments without departing from the scope and spirit of the present invention.
