Title: Cantilevered rotatable carcass carrier

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a water carrier, and more particularly to a cantilevered rotatable carcass carrier. 
     2. Description of the Prior Art 
     A conventional water recreational carrier is limited to the movement of two-dimensional space on the water, so the view and activity range of the water recreation is limited thereto. This also results in limitation of the space and type of recreations on the water. A glass boat is developed for submarine activities under the water to provide more diverse views. The conventional glass boat is provided with windows at the lower cabin or a transparent base. The view range and activity range of this water recreational carrier is limited to the two dimensional space under the water surface. It is unable to go deeper and subjected to the interference of water surface. Accordingly, the inventor of the present invention has devoted himself based on his many years of practical experiences to solve these problems. 
     SUMMARY OF THE INVENTION 
     The primary objective of the present invention is to provide a cantilevered rotatable carcass carrier to overcome the problem that the conventional water recreational carrier is limited to the type of two-dimensional space on the water. The present invention provides a novel water recreational carrier, broadening the recreational space on the water in a submarine mode and a watch mode for the demands of different situations. 
     In order to achieve the aforesaid objective, the cantilevered rotatable carcass carrier of the present invention comprises a main carcass and two secondary carcasses. The two secondary carcasses are pivotally connected to two sides of the main carcass through two first cantilevers and parallel to the main carcass. The secondary carcasses are turned with the first cantilevers as the axles. The secondary carcasses are further pivotally connected with second cantilevers. The secondary carcasses further pivotally connected with an airtight cabin through the second cantilevers. The airtight cabin has a transparent cabin cover, and the transparent cabin cover is adapted to open or close the airtight cabin. 
     The cantilevered rotatable carcass carrier of the present invention uses the secondary carcasses for the airtight cabin to be located under the main carcass to form a submarine mode or to be located above the main carcass to form a watch mode, broadening the recreation space on the water, such that the recreational space on the water is not limited to the type of two-dimensional space on the water. The present invention provides a novel water recreational carrier for the demands of different situations.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings. 
       FIG. 1  is a perspective view of the present invention in a rest mode. The present invention discloses a cantilevered rotatable carcass carrier. The cantilevered rotatable carcass carrier comprises a main carcass  10 , two first cantilevers  30 , two secondary carcasses  20 , two second cantilevers  50 , and an airtight cabin  40 . 
     The main carcass  1  is a carcass having power. The main carcass  1  comprises a cockpit  11 . The cockpit  11  is provided with a first control unit therein. The bottom side of the main carcass  10  is provided with an engine and a rudder. The engine and the rudder are connected with the first control unit, so that the engine and the rudder are controlled by the first control unit. The rear of the main carcass  10  further has an anchorage area  12 . In this embodiment of the present invention, the main carcass  10  is a mono-carcass yacht to lower R&amp;D cost and production cost so as to enhance the economic benefits. 
     The two first cantilevers  30  are disposed at two sides of the main carcass  10  and pivotally connected to the center of the gravity of the main carcass  10 . The first cantilevers  30  are transversely connected to the main carcass  10 . One end of each cantilever  30  is pivotally connected to the main carcass  10 , and another end of each cantilever  30  extends toward the outside of the main carcass  10 . It is noted that the first cantilevers  30  are axially telescopic. In this embodiment of the present invention, the first cantilevers  30  are operated in an oil hydraulic way and symmetrically pivoted to the middle rear section of the main carcass  10 . 
     The two secondary carcasses  20  are respectively disposed at one end of the main carcass  10 , away from the first cantilevers  30 , and located at left and right sides of the main carcass  10 , enhancing the stability of the cantilevered rotatable carcass carrier and behavior at sea. In this embodiment of the present invention, the length of the secondary carcasses  20  is shorter than that of the main carcass  10 . The length of the secondary carcasses  20  is greater than the height of the main carcass  10 . The width of the secondary carcasses  20  is narrower than that of the main carcass  10 . The two secondary carcasses  20  are disposed at left and right sides of the rear section of the main carcass  10  and parallel to the main carcass  10 . The rear sections of the secondary carcasses  20  extend to the left and right sides of the rear section of the main carcass  10 . The first cantilevers  30  are pivotally connected to the front sections of the secondary carcasses  20 , such that the secondary carcasses  20  can be turned to the left and right sides above the main carcasses  10  or to the left and right sides under the main carcasses  10 . Furthermore, through the first cantilevers  30  to extend or retract axially, the secondary carcasses  20  extend outward apart from the main carcass  10  to enhance the stability of the cantilevered rotatable carcass carrier, alternatively, the secondary carcasses  20  are attached to the main carcass  10  to lower the resistance to generate waves for the prow of the cantilevered rotatable carcass carrier. 
     The second cantilevers  50  are connected to the secondary carcasses  20 , respectively. The second cantilevers  50  are transversely connected to the secondary carcasses  20  and parallel to the first cantilevers  30 . One end of each secondary cantilever  50  is pivotally connected to the corresponding secondary carcass  20 , and another end of each secondary cantilever  50  extends between the secondary carcasses  20 . It is noted that the secondary cantilevers  50  are axially telescopic. The secondary cantilevers  50  are operated in an oil hydraulic way and symmetrically pivoted to the rear sections of the secondary carcasses  20 . 
     The airtight cabin  40  is disposed at one end of the secondary cantilevers  50 , away from the secondary carcasses  20 , such that the airtight cabin  40  is pivotally connected between the secondary carcasses  20 . In this embodiment of the present invention, the airtight cabin  40  is pivotally connected between the rear sections of the secondary carcasses  20  and parallel to the secondary carcasses  20 . The airtight cabin  40  is just located at the anchorage area  12  at the rear of the main carcass  10 . The airtight cabin  40  has a transparent cabin cover  41 . The transparent cabin cover  41  is adapted to open or close the airtight cabin  40 . The transparent cabin cover  41  is provided with a second control unit therein. The second control unit is connected with the engine and the rudder, so that the engine and the rudder are controlled by the second control unit. 
       FIG. 2  is a perspective view of the present invention in a watch mode. The cantilevered rotatable carcass carrier having three carcasses has the advantages of high stability and high wave-resistant capability and steadiness. The secondary carcasses  20  and the main carcass  10  are connected by the first cantilevers  30 . The rear sections of the secondary carcasses  20  are pivotally connected with the airtight cabin  40  which has operation and rest functions. When the secondary carcasses  20  are driven to turn by the first cantilevers  30  for the airtight cabin  40  to ascend above the main carcass  10 , the cantilevered rotatable carcass carrier is in a watch mode. At this time, the airtight cabin  40  can overlook water scenery from a high place. The front sections of the secondary carcasses  20  still maintain a certain range of area in contact with the water, continuing to provide buoyancy for keeping the stability and anti-wave capability of the three carcasses formed by the main carcass  10  and the two secondary carcasses  20 . 
     It is noted that the airtight cabin  40  are pivotally connected to the secondary carcasses  20  by the secondary cantilevers  50 . Therefore, when the secondary carcasses  20  are driven to turn by the first cantilevers  30 , the airtight cabin  40  can maintain its horizontal state, not inclining along with the turning of the secondary carcasses  20 . Furthermore, the inclined angle of the airtight cabin  40  can be adjusted by the user through the second control unit, providing more diverse watch angles. 
     Besides, when the cantilevered rotatable carcass carrier is in a watch mode, the engine and the rudder can be controlled by using the second control unit so as to sail the cantilevered rotatable carcass carrier. At this time, the cantilevered rotatable carcass carrier uses the advantage of three-carcass configuration to provide a stable sailing for water experience at a high place. 
       FIG. 3  is a perspective view of the present invention in a submarine mode. When the secondary carcasses  20  are driven to turn by the first cantilevers  30  for the airtight cabin  40  to descend under the main carcass  10 , the cantilevered rotatable carcass carrier is in a submarine mode. At this time, the airtight cabin  40  is under the water to operate and control the cantilevered rotatable carcass carrier and to provide a space under the water for rest. Through the large-sized transparent cabin cover  4 , the user can watch the special scenery under the water. Through the secondary carcasses  20  connected with the main carcass  10  to provide the essential air, water, electricity, and so on, the user can rest and explore underwater for a long time. 
     It is noted that the airtight cabin  40  can go deep underwater by using the turning of the secondary carcasses  20 . Furthermore, the inclined angle of the airtight cabin  40  is adjustable through the second control unit, providing more diversity. This is different from the view range and activity range of the two dimensional space, avoiding interference of water surface. 
     It is noted that no matter in a watch mode or in a submarine mode, the cantilevered rotatable carcass carrier uses the secondary carcasses  20  to maintain a certain range of area in contact with the water so as to continue providing buoyancy for keeping the stability and anti-wave capability of the three carcasses formed by the main carcass  10  and the secondary carcasses  20  at two sides. Thus, the cantilevered rotatable carcass carrier in a watch mode or in a submarine mode can have a better action. Furthermore, through the first cantilevers  30  to extend outward in the axial direction, the secondary carcasses  20  extend outward apart from the main carcass  10  to enhance the stability and anti-wave capability of the cantilevered rotatable carcass carrier. 
       FIG. 4  is a perspective view of the present invention in a cruise mode. As shown in  FIG. 1  and  FIG. 4 , when the cantilevered rotatable carcass carrier performs a cruise, the first cantilevers  30  are retracted axially for the secondary carcasses  20  to attach to the main carcass  10  so as to lower the resistance to generate waves for the prow of the cantilevered rotatable carcass carrier and to enhance the streamline of the cantilevered rotatable carcass carrier. This is beneficial for the cantilevered rotatable carcass carrier to cruise. 
     It is noted that the pivotal ends of the first cantilevers  30  and the secondary carcasses  20  as well as the pivotal ends of the second cantilevers  50  and the airtight cabin  40  can be pivotally connected in a multi-axis way at different angles. 
     The features and expected effects of the present invention are described hereinafter. 
     The cantilevered rotatable carcass carrier of the present invention uses the secondary carcasses for the airtight cabin to be located under the main carcass to form a submarine mode or to be located above the main carcass to form a watch mode, broadening the recreation space on the water, such that the recreation space on the water is not limited to the type of two-dimensional space on the water. The present invention provides a novel movement dimension for water activities, with different modes for the demands of different situations. 
     Although particular embodiments of the present invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the present invention. Accordingly, the present invention is not to be limited except as by the appended claims.
