BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a safety boat assembly and more specifically to a safety boat assembly which contains air bags operatively associated with a body member and auxiliary body members for improving a floating force and mercury disposed in a tubular pole for improving the gravity force thereof. The safety boat assembly also includes automatic fresh air supply systems and an automatic lighting system, for use when the boat assembly is capsized by accident, so as to facilitate the rescue of the passengers therein the various dangers. 
     2. Description of the Prior Art 
     Safety boats are well known in the art which include air gabs. However, there are many problems, for example, when the boat is tilted over, there is no fresh air supply and there is no source of light. Furthermore, such boats perform poorly in the heavy seas since these boats are usually light weight. 
     SUMMARY OF THE INVENTION 
     Accordingly, it is an object of the present invention to provide an improved safety boat assembly for protecting the passengers against various dangers when the boat is capsized. 
     Another object of the present invention is to provide a safety boat assembly which includes a plurality of air bags disposed therein for increasing the buoyancy and sailing performance thereof. 
     A further object of the present invention is to provide a safety boat assembly which is structured with a breathing device disposed within cabins thereof for automatically introducing the fresh air into the cabins thereof when the boat is turned over. 
     Still another object of the present invention is to provide a safety boat assembly which includes a tubular pole which stands erect on the boat assembly and which is filled with a dense material in the lower portion of the pole so that the weight of the dense material adds its weight to the weight of the boat assembly for preventing the boat assembly from being turned over because of strong wind and waves. Also, the pole is extendable out of the bottom surface of the boat assembly so as to enable one to esily return the capsized boat assembly to its upright position by grasping and lifting the end portion of the extended pole with little effort. 
     Yet another object of the present invention is to provide a boat assembly which includes safety belts for passengers so as to prevent their separation from the capsized boat assembly in the water and waves. 
     A further object of the present invention is to provide a boat assembly which includes several pieces of equipment, such as for example rubber handles fixed in the interior of the boat wall for being grasped by the passengers, a light automatically operated by a gravity on/off switch and a view window for observing the outside scene when the boat assembly is turned over. 
     Other objects and further scope of applicability of the present invention will become apparent from the detailed description given hereinafter. It should be understood, however, that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description.

     DETAILED DESCRIPTION OF THE INVENTION 
     Referring now in detail to the drawings for the purpose of illustrating a preferred embodiment of the present invention, the safety boat assembly as shown in FIGS. 1, 2 and 3 includes a body member 1 which contains a front cabin 3 and a rear cabin 4 disposed in the middle and rear portions thereof, respectively, and a front chamber 2 disposed in the front portion thereof for containing an air bag 2&#39; disposed therein. The body member 1 is provided with a plurality of side chambers 5 attached to both sides thereof for containing a plurality of air bags 5&#39; disposed therein. The front cabin 3 is provided with an air passing cylinder attached to the interior of a front wall 3&#39; for containing a rectangular, tubular air inlet member 7 at an opening 6&#39; disposed at the air passing cylinder 6. The air inlet member 7 extends to the bottom surface of the front cabin 3 and contains a circular tube 7&#39; disposed therein for readily introducing the air through apertures 16, as shown in FIG. 8, when the boat assembly is capsized. A tubular supporting member 17 attached to the interior of the front wall 3&#39; of the front cabin 3 is adapted to receive a tubular pole 8. The tubular supporting member 17 and tubular pole 8 have a rectangular configuration for tightly engaging the pole 8 within the supporting member 17. The tubular pole 8 contains a dense material 8&#39; disposed in lower portion thereof for increasing the pole&#39;s weight and that of the boat assembly so as to stabilize the boat assembly in heavy waves. The tubular pole 8 is made of a solid material such as metal, hard plastic, or the like. Also, the tubular pole 8 has a plurality of apertures 18 for adjusting the pole 8 to the supporting member 17 by aligning a bolt 19 through an aperture 18 disposed in the supporting member 17. If necessary, the pole 8 can be moved to jut out of the bottom surface of the boat assembly as shown in FIG. 4 so as to allow one to easily grasp it and return the capsized boat assembly 1 to its upright position. 
     A light device 9-, as shown in FIGS. 1 and 2, is attached to the interior of the wall 3&#39; of the front cabin 3. The light device 9 contains a battery B, a on/off gravity switch 9&#39;, and a light bulb 20. The light bulb 2 .is automatically lighted by the gravity switch when the boat assembly is turned over (FIG. 13). The light device 9 is provided near a view finding window 10 for allowing one to observe the outside scene with the lightened bulb 20 when the boat assembly 1 is capsized. 
     A wall 4&#39; disposed between the front cabin 3 and the rear cabin 4 is provided with a rectangular U-shaped pipe 13 having an engagement member 13&#39;. The U-shaped pipe 13 is arranged on both sides of the wall 4&#39; for introducing fresh air from the front cabin 3 to the rear cabin 4 when the boat assembly is capsized as shown in FIGS. 9, 10, and 11. The U-shaped pipe 13 is mounted to the wall 4 by a screw 14 having a short rubber cover 15 through the engaging member 13&#39; thereof (FIG. 1). Air bag side chambers 5 are attached to the body member 1 by the screws 14 having the short rubber cover 15 disposed at both ends thereof. Also, the screws 14 disposed in the lower portion of the side wall in the cabins 3 and 4 have a long rubber cover 15&#39; for use by passengers as a grasping handle (FIGS. 1 and 4). 
     A plurality of apertures 11 disposed in the side wall of 
     the cabins 3 and 4 are adapted to receive hooks 12&#39; of a safety belt 12 for securing the passengers to the cabins 3 and 4 (FIG. 12). 
     In operation, when the boat assembly is turned over during sailing, the passenger is prevented frm being separated from the boat assembly since the passenger is secured to the safety belt I2 which is attached to the interior walls of the cabins 3 and 4, and the passenger is able to grasp the handle 15&#39;. At this time, as shown in FIG. 7, the fresh air in the atmosphere is introduced into the front cabin 3 through the plurality of apertures 16 disposed in the tubular air inlet member 7 and the opening 6&#39; of the air passing cylinder 6. And the fresh air is introduced from the front cabin 3 to the rear cabin 4 through the U-shaped pipe 13 for supplying the fresh air to the victim (FIG. 11). At this time, simultaneously, the light bulb 20 is lighted by the on/off gravity switch and the victim can observe the outside scene through the view finding window 10 (FIG. 13). Also, the capsized boat assembly can be easily returned to its upright position by using the end portion of the pole 8 which extends out of the bottom surface thereof with little effort being required by the rescuer. 
     Further according to the present invention, the probability of being capsized by a strong wind or waves is greatly reduced because of the gravity function of the dense material 8&#39; disposed in the lower portion of the rectangular pole 8. This dense material may be mercury, for example. 
     Also, the safety boat assembly of the present invention contains the plurality of air bags 2&#39; and 5&#39; disposed within the cabins 3 and 4, and air bag side chambers 5 for improving the floating force thereof. 
     The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included in the scope of the following claims.
