Schematic diagram showing the relationship with the first and second means Schematic diagram of the main part showing another structure of the first and second means shown in FIG. The expanded sectional view for demonstrating the relationship between the 1 * 2 means of this invention, and a coupling tool FIG. 1 is a schematic plan view of the rotor blade of the embodiment shown in FIG. Plane schematic diagram showing another embodiment of rotor blade Plane schematic diagram showing joint fittings that control the expansion of rotor blades

  In the figure, reference numeral 1 denotes a four-wheel drive vehicle (referred to as a vehicle). As is well known, each wheel 2, 2, etc. (indicated by a single number in a plurality of cases) has a drive source. It is an example and is not limited.

  Further, 3 is a pseudo helicopter, and the pseudo helicopter 3 is preferably erected at a lightweight base 5 made of resin, lightweight metal (aluminum) or the like, and at a predetermined position (also movable) of the base 5. In addition, the vehicle 1 is supported in the space (supported apart from the base 5), for example, the relationship between the four pillars 6 and 6 and the first and second means shown in FIGS. In a plan view, a schematic diagram, etc., one side is connected to the coupling 7, 7 (first means) provided on one side of the axle 200 of the wheel 2 and the base end side 7 b of the coupling 7. A universal joint A (automatic joint) and a reduction mechanism 8 (spur gear group, planetary gear group) provided on the other side of the universal joint A are configured. As shown in FIGS. 1 to 1-2, the coupling 7 is fitted to the end of the wheel 2 and is synchronized with the wheel 2. Therefore, the rotation of the wheel 2 meshes with the bevel gear 11 and the coupling 7, the universal joint A, the speed reduction mechanism 8, and the bevel gears 11 and 11 (first gear) connected to the speed reduction mechanism 8. The structure is such that the bevel gears 12 and 12 (second gear) are transmitted to the vertical shaft 15, and as described above, the rotation of the wheel 2 is decelerated and transmitted to the rotary blades 16 and 16, and the rotary blades 16 are transmitted. Rotate. With this rotation, the buoyancy (lift) of the pseudo helicopter 3 is generated. The structure of the coupling 7 is an example, and although not shown, a coupling mechanism such as a fitting method, a coupling method, or a fitting jig method for the wheel 2 is possible. Further, the relationship between the bevel gear 12 and the bevel gear 13 is an example, and various transmission mechanisms such as a spur gear, a spline gear, and a planetary gear are possible although not shown. As shown in FIG. 1-2, it is desirable that the length L of the universal joint A be adjustable in consideration of the size of the vehicle 1, the vehicle height, and the like. The same applies to the pillar 6.

  1-3 is a schematic diagram showing the relationship with the first and second means shown in FIG. 1-3. Instead of the coupling 7, each of the arm pieces 20 and 20 holding the wheel 2 (tire catch “first means”). ]) And the like, and the base end of the arm piece 20 is supported by the flywheels 21, 21 and the like. The speed reduction mechanism 8 is connected via a universal joint A provided on the flywheel 21. Others are in accordance with the embodiment of FIG. 2 is another embodiment in which the bevel gear 11 is provided on the first shaft 22 provided on the flywheel 21, and the bevel gear 12 meshing with the bevel gear 11 and the vertical shaft 15 are erected. . In the figure, reference numeral 20 a denotes the free end side of the arm piece 20. Reference numeral 20 b denotes a base end side of the arm piece 20 and is supported by the flywheel 21.

  As described above, the vehicle 1 travels, arrives at the base 5 and stops. For example, the chassis of the vehicle 1 is placed on the pillars 6 provided at the four corners of the base 5. Then, the vehicle 1 is lifted by a hydraulic cylinder, supported on a pillar 6 and fixed with a jig such as a claw (can be released), and the vehicle 1 and the wheel 2 are supported in the air. In this state, the case 23 is similarly fixed in the air, and the wheel 2 is held by the coupling 7 provided with the base end side 7b on the case 23 or the free end side 20a of the arm piece 20. When the vehicle 1 is driven and the wheel 2 is rotated, the rotation of the wheel 2 is transmitted from the coupling 7 or the arm piece 20 to the flywheel 21. While this coupling 7 etc. rotate, the universal joint A rotates in synchronism with this rotation. The rotation causes the bevel gear 11 to rotate, and the bevel gear 12 that meshes with the bevel gear 11 rotates. The rotation of the bevel gear 12 becomes the rotation of the vertical shaft 15, so that the rotary blade 16 rotates and buoyancy is generated. That is, the vehicle 1 becomes a cockpit of the pseudo helicopter 3 and can fly by the pseudo helicopter 3 including the vehicle 1. With this flight, the object of the present invention is achieved. When the flight is stopped, the rotor 16 is stopped by stopping the operation of the vehicle 1, so that the landing can be made. Thereafter, the detachment of the vehicle 1 from the base 5 is the reverse of the above-described operation, and the details are omitted.

  The vertical rod 15 is accommodated in a column case 40 erected on the case 23 provided with the arm pieces 20, and ensures rotation and safety. Considering the vertical shaft 15 and the column case 40 upright, improving the strength and preventing blurring, etc., the column case 40 is framed by the frame piece 42, and the four corners of the frame piece 42 are A shaped housing 41 is provided. The vertical shaft 15 reaches the outside of the housing 41 via a bearing (not shown) built in the housing 41 and pivotally supports the rotary blade 16 at the upper end thereof. The pseudo helicopter 3 is provided with a tail 17 (tail rotor) if necessary, and direction steering is operated manually or automatically from the driver's seat (the same applies to other structures). Thereby, the directionality of a flight direction is ensured. Moreover, the column case 40 accommodates the vertical gutter 15 in order to reinforce the vertical gutter 15 and ensure safety. The column case 40 is reinforced by a reinforcing plate 40a.

  Although not shown, other structures for lifting the vehicle 1 may be, for example, a structure in which the pillar 6 can be expanded or contracted, or a structure in which a support means such as a support base can be expanded and contracted.

  Next, the embodiment of FIGS. 4 and 5 is intended for the floating of the pseudo helicopter 3 and / or the improvement of flight (enhancement of functions), and in a preferred example, it is as follows. That is, the blade piece 1600a of the rotary blade 1600 has a large structure. The rotary blade 1600 is mounted on the vehicle 1. For example, a pair of joint metal fittings 30 and 31 pivotally supported on the main shafts of the vertical shaft 15 and the rotary blade 1600 and the joint metal fittings 30 and 31 are connected in the horizontal direction. A universal joint A1 (extension mechanism) including the supported joint 32 (joint rod) is employed. The rotary wing 1600 is arranged in the outer side 100 of the vehicle 1 and in the front-rear directions 101 and 102, and moves to the outside of the vehicle 1. Thereby, in the longitudinal direction of the vehicle 1, the adjacent blade piece 1600a is not in contact, and the rotating blade 1600 can be rotated safely. The blade piece 1600a of the rotary blade 1600 shown in FIGS. 4 and 5 has a larger structure than the blade piece 16a of the other illustrated rotary blade 16.

  The above-described embodiment and the structure and effect described in the drawings show preferred examples of the present invention. Accordingly, the invention having the same effects and features as those of the present invention in the description of other embodiments and / or the drawings, which are not shown and / or described, and / or the drawings are naturally within the scope of the present invention. .
