On the other hand, the second propeller 532 and the third propeller 533 arranged on the other diagonal line rotate in the same leftward direction. The first to fourth propellers 531, 532, 533, 534 rotate to send air toward the lower side of the main body 3. Therefore, the pitch angles of the first propeller 531 and the fourth propeller 534 are the same as each other, but the pitch angles of the second propeller 532 and the third propeller 533 are opposite. Further, the pitch angles of the first to fourth propellers 531, 532, 533, 534 are fixed.

FIG. 6 is a plan view showing a modified example of the moving means of this embodiment.
As shown in FIG. 6, the moving means 5A of the present modification has a moving means body 51A, first to third driving means 521, 522, 523, and first to third propellers 531, 532, 533. You may have. As described above, the moving means of the present embodiment may have a plurality of driving means and a plurality of propellers. The number of drive means and propellers may be plural and is not particularly limited.

  The moving means main body 51A is formed in a substantially triangular shape as a whole, and is also formed in a plate shape having a predetermined thickness (see FIGS. 3 and 4). The moving means main body 51A has circular holes 541, 542, and 543 provided at the positions of the respective vertices. The holes 541, 542, and 543 penetrate the moving means main body 51A in the thickness direction. The first to third drive means 521, 522, 523 and the first to third propellers 531, 532, 533 are installed in the first to fourth drive means 521, 522, 523, 524 and the first to fourth drive means described above with reference to FIG.

FIG. 7 is a block diagram showing the control unit of this embodiment.
FIG. 8 is a block diagram showing the transmitter of this embodiment.
As described above with reference to FIG. 5 and FIG. 6, the moving means 5A shown in FIG. 6 is different from the moving means 5 shown in FIG. 5 in the number of drive means and propellers, but is different in the installation mode of each member. It is similar to the moving means 5 shown in FIG. Therefore, in the following description, the moving means 5 shown in FIG. 5 will be taken as an example.

  The controller 7 is provided inside the main body 3 and controls the traveling (running) of the air cushion machine toy 2. The control unit 7 includes a control circuit 71, a drive circuit 72, a reception circuit 73, a reception antenna 74, a battery 75, and a power switch 76. The receiving circuit 73 receives the control signal transmitted from the transmitter 8 shown in FIG. The control circuit 71 generates a control signal based on the signal received by the receiving circuit 73. The drive circuit 72 controls the drive output of the first to fourth drive means 521, 522, 523, 524 based on the control signal generated by the control circuit 71. In this way, the control unit 7 individually controls the drive output of each of the first to fourth drive means 521, 522, 523, 524 that drives the first to fourth propellers 531, 532, 533, 534. When the power switch 76 is turned on, the battery 75 supplies a voltage to the control circuit 71, the driving circuit 72, the receiving circuit 73, and the first to fourth driving means 521, 522, 523, 524.

  The transmitter 8 is provided separately from the main body 3 of the air cushion machine toy 2, and transmits a signal for controlling the progress (running) of the air cushion machine toy 2 to the control unit 7. The transmitter 8 includes a transmission circuit 81, a signal generation circuit 82, an operation unit 83, a transmission antenna 84, a battery 85, and a power switch 86. The operator of the air cushion machine toy 2 can control the progress (running) of the air cushion machine toy 2 by operating the operation unit 83. The operation unit 83 has an operation lever (not shown) that can be operated with, for example, a fingertip. The signal generation circuit 82 generates a signal based on the operation of the operation unit 83 by the operator. The transmission circuit 81 transmits the signal generated by the signal generation circuit 82 to the control unit 7 as a radio wave or the like via the transmission antenna 84. When the power switch 86 is turned on, the battery 85 supplies a voltage to the transmission circuit 81 and the signal generation circuit 82.

  When the operator puts the main body 3 of the air cushion machine toy 2 on the ground 28 and turns on the power switch 76, the drive circuit 72 of the control unit 7 causes the first to fourth drive means 521, 522, 523, and 524 to mutually move. Drive with the same drive output. As a result, the first to fourth propellers 531, 532, 533, 534 rotate at the same speed and send air toward the lower side of the main body 3. Then, as described above with reference to FIGS. 3 and 4, the air cushion machine toy 2 floats above the ground 28 at the position where the main body 3 is stopped.

  At this time, the first propeller 531 and the fourth propeller 534 arranged on one diagonal line and the second propeller 532 and the third propeller 533 arranged on the other diagonal line rotate in opposite directions at the same speed. To do. Therefore, the reaction due to the rotation of the first to fourth propellers 531, 532, 533, 534 cancels each other. Therefore, the main body 3 of the air cushion machine toy 2 floats above the ground 28 at the stopped position without turning left and right.

  Next, when the operator advances the air cushion machine toy 2 from the levitated state, the operator appropriately operates the operation unit 83 of the transmitter 8. Then, the signal generation circuit 82 generates a signal for increasing the drive output of the third drive unit 523 and the fourth drive unit 524. Then, the signal generated by the signal generation circuit 82 is transmitted to the control unit 7 via the transmission antenna 84. The signal transmitted from the transmitting antenna 84 is received by the receiving circuit 73 via the receiving antenna 74. The control circuit 71 generates a control signal based on the signal received by the reception circuit 73, and transmits the control signal to the drive circuit 72. The drive circuit 72 raises the drive output of the third drive means 523 and the fourth drive means 524 based on the control signal generated by the control circuit 71. As a result, the rotational speeds of the third propeller 533 and the fourth propeller 534 arranged on the rear side of the moving means main body 51 increase. Then, the amount of air blown on the rear side of the moving means main body 51 increases. As a result, the moving means 5 advances while tilting the moving means main body 51. When the moving means 5 moves forward, the moving force is transmitted from the moving means 5 to the main body 3 via the buffer portion 6. In this way, the air cushion machine toy 2 can move forward from the state where the main body 3 is levitated.

  When the air cushion machine toy 2 moves backward from the floating state, the signal generation circuit 82 generates a signal for increasing the drive output of the first drive means 521 and the second drive means 522. Further, when the air cushion machine toy 2 moves from the floating state to the left, the signal generation circuit 82 generates a signal for increasing the drive output of the second drive means 522 and the fourth drive means 524. Further, when the air cushion machine toy 2 advances from the floating state to the right, the signal generation circuit 82 generates a signal for increasing the drive output of the first drive means 521 and the third drive means 523. Then, the moving means 5 tilts the moving means main body 51 when moving backward, moving leftward, and moving rightward. By transmitting the moving force from the moving means 5 to the main body 3 via the buffer section 6, the air cushion machine toy 2 moves backward from the state where the main body 3 is levitated, moves to the left, or moves to the right. Or proceed to. Note that FIG. 4 illustrates a state in which the air cushion machine toy 2 advances to the left from a state in which the main body 3 is levitated.

  Here, as described above, the moving means 5 tilts the moving means main body 51 to move, and transmits the moving force to the main body 3. Therefore, when the cushioning portion 6 is not provided, as in the case where the moving means is directly fixed to the main body, for example, the air cushion machine toy moves (progresses) by tilting the main body. Become. Then, the gap between the skirt portion and the ground or the water surface becomes uneven in the peripheral portion of the lower portion of the main body, and the amount of air flowing out of the air cushion machine toy through the gap may become uneven. is there. Then, the air cushion machine toy may become unstable in its floating and moving.

  On the other hand, the air cushion machine toy 2 according to the present embodiment includes the buffer section 6 that connects the main body 3 and the moving means 5. As shown in FIG. 4, the buffer portion 6 is an elastic body having elasticity such as rubber or vinyl, and suppresses the inclination of the moving means 5 from being transmitted to the main body 3. Therefore, when the moving means 5 tilts the moving means main body 51 to move the main body 3, the tilt of the moving means 5 is suppressed from being transmitted to the main body 3. Therefore, it is possible to prevent the gap 29 between the skirt portion 4 and the ground surface 28 from becoming nonuniform in the peripheral portion of the lower portion of the main body 3, and make the amount of air flowing out of the air cushion machine toy 2 nonuniform. Can be suppressed. Therefore, it is possible to prevent the floating and movement of the air cushion machine toy 2 from becoming unstable. As a result, the air cushion machine toy 2 according to the present embodiment can move stably in any direction. Further, the operator can easily remotely control the air cushion machine toy 2.

  Further, since the buffer portion 6 is formed of the elastic body, it is possible to suppress the inclination of the moving means 5 from being transmitted to the main body 3 with a relatively simple configuration. Further, as shown in FIG. 4, when the buffer portion 6 has a bellows structure, the inclination of the moving means 5 can be more reliably suppressed from being transmitted to the main body 3 with a relatively simple configuration.

  The air cushion machine toy 2 can move not only from the levitated state to the front, rear, left and right, but also from the levitated state to the left and right. When turning the air cushion machine toy 2 from the levitated state to the right, the operator appropriately operates the operation unit 83 of the transmitter 8. Then, the signal generating circuit 82 generates a signal for increasing the drive output of the second driving unit 522 and the third driving unit 523. Then, the signal generated by the signal generation circuit 82 is transmitted to the control unit 7 via the transmission antenna 84. The signal transmitted from the transmitting antenna 84 is received by the receiving circuit 73 via the receiving antenna 74. The control circuit 71 generates a control signal based on the signal received by the reception circuit 73, and transmits the control signal to the drive circuit 72. The drive circuit 72 raises the drive output of the second drive means 522 and the third drive means 523 based on the control signal generated by the control circuit 71. As a result, the rotational speeds of the second propeller 532 and the third propeller 533 arranged on the other diagonal line increase.

  As shown in FIG. 5, since the second propeller 532 and the third propeller 533 rotate in the same left direction as each other, when the rotation speed of the second propeller 532 and the third propeller 533 increases, the moving means main body 51 A force is generated to turn to the right. As a result, the moving means 5 turns to the right. At this time, the moving means 5 does not necessarily tilt the moving means main body 51 and turn right. When the moving means 5 turns to the right, the right turning force is transmitted from the moving means 5 to the main body 3 via the buffer portion 6. In this way, the air cushion machine toy 2 can turn to the right from the state where the main body 3 is levitated.

  When the air cushion machine toy 2 turns to the left from the floating state, the signal generation circuit 82 generates a signal for increasing the drive output of the first drive means 521 and the fourth drive means 524.

  In this way, the air cushion machine toy 2 according to the present embodiment can move in any direction. At this time, the buffer unit 6 suppresses the inclination of the moving unit 5 from being transmitted to the main body 3. Therefore, the air cushion machine toy 2 can move stably. Further, the operator can easily remotely control the air cushion machine toy 2.

9 and 10 are cross-sectional views showing an air cushion machine toy according to a second modified example of the present embodiment.
9 is a cross-sectional view corresponding to the cross-section AA shown in FIG. 1, and is a cross-sectional view showing a state in which the air cushion machine toy according to the modified example of the present embodiment floats and stands still. FIG. 10 is a cross-sectional view corresponding to the cross-sectional view taken along the cross section AA shown in FIG. 1 and showing a state in which the air cushion machine toy according to the modified example of the present embodiment is floating and moving to the left.

  The buffer portion 6A of the present modification is formed of a resin or metal having a property harder than the elastic body, instead of the elastic body, and has a ball joint structure. In this respect, the air cushion machine toy 2B according to the present modification example is different from the air cushion machine toy 2 described above with reference to FIG. For example, the buffer portion 6A has a ball stud having a ball portion. The buffer portion 6A is held by the holding portion 34 provided inside the main body 3 at a substantially central portion in the left-right direction of the main body 3.

  The moving means 5B of the present modification is connected to the ball stud of the buffer portion 6A in a socket provided at the center of the moving means main body 51, and is attached to the main body 3 via the buffer portion 6A. That is, the buffer 6A connects the body 3 and the moving means 5B at the center of gravity of the moving means 5B, and suppresses the inclination of the moving means 5B from being transmitted to the body 3.

  In this modification, the buffer portion 6A may have a socket and the moving means main body 51 may have a ball stud. That is, the moving means 5B of this modification may be attached to the main body 3 via the buffer portion 6A having a ball joint structure. The other structure is the same as the structure of the air cushion machine toy 2 described above with reference to FIGS. 1 to 8.

  Similar to the moving means 5 described above with reference to FIG. 5, the moving means 5B of this modified example tilts the moving means main body 51 to move, and transmits the moving force to the main body 3. As a result, the air cushion machine toy 2B advances, retracts, advances to the left, or advances to the right from the state where the main body 3 is levitated. Note that FIG. 10 shows a state in which the air cushion machine toy 2B advances to the left from a state in which the main body 3 is levitated.

  According to this modification, since the buffer 6A has the ball joint structure, the moving means 5B tilts or rotates around the buffer 6A. Therefore, when the moving means 5B tilts the moving means main body 51 to move the main body 3, transmission of the tilt of the moving means 5B to the main body 3 is suppressed. Therefore, it is possible to prevent the gap 29 between the skirt portion 4 and the ground 28 from becoming nonuniform in the peripheral portion of the lower portion of the main body 3, so that the amount of air flowing out of the air cushion machine toy 2B becomes nonuniform. Can be suppressed. As a result, the same effects as those of the air cushion machine toy 2 described above with reference to FIGS. 1 to 8 can be obtained.

  Further, compared with the buffer section 6 described above with reference to FIGS. 3 and 4, the buffer section 6A of the present modification connects the main body 3 and the moving means 5B in a narrow range. Therefore, the inclination of the moving means 5B can be suppressed from being transmitted to the main body 3, and the size of the buffer portion 6A can be suppressed. As a result, the size of the main body 3 can be secured, and the flexibility of the shape and design of the main body 3 can be improved.

FIG. 11: is sectional drawing showing the air cushion machine toy which concerns on the 3rd modification of this embodiment.
Note that FIG. 11 is a cross-sectional view corresponding to the cross-sectional view taken along the cross section AA shown in FIG. 1 and showing a state in which the air cushion machine toy according to the modified example of the present embodiment floats and stands still.

  In the air cushion machine toy 2E according to the present modification, the cushioning portion 6D has a ball joint structure 61 and an elastic body 62. The ball joint structure 61 is similar to the buffer portion 6A of the ball joint structure described above with reference to FIGS. 9 and 10. The elastic body 62 is provided between the main body 3 and the moving means 5 and connects the main body 3 and the moving means 5. The elastic body 62 is, for example, a coil spring. Alternatively, the elastic body 62 may be elastic, such as rubber or vinyl. Further, the elastic body 62 may have a bellows structure. That is, the present modification has a structure in which the buffer portion 6 described above with reference to FIGS. 3 and 4 and the buffer portion 6A described above with reference to FIGS. 9 and 10 are combined.

  According to this modification, the moving unit 5B is stably supported by the main body 3 via the buffer section 6D. Therefore, the air cushion machine toy 2E can prevent the moving means 5B from tilting excessively even when it contacts an obstacle such as a wall, and can more stably move or turn. You can

Next, a second embodiment of the present invention will be described.
In addition, when the constituent elements of the air cushion machine toy according to the second embodiment are the same as the constituent elements of the air cushion machine toy according to the first embodiment described above with reference to FIGS. 1 to 8, overlapping description will be omitted.

As shown in FIG. 13, the first frame body 511 is connected and fixed to the leg portion 36 of the main body 3A. The structure in which the first frame body 511 is fixed to the leg portion 36 of the main body 3A is the same in the second to fourth frame bodies 512, 513, and 514.

  The first driving means 521 is arranged at the center position of the hole 541 formed in the first frame body 511, and is fixed to the first frame body 511 via the support member 551. The second driving means 522 is arranged at the center position of the hole 542 formed in the second frame 512, and is fixed to the second frame 512 via a supporting member (a member corresponding to the supporting member 551). The third driving unit 523 is arranged at the center position of the hole 543 formed in the third frame body 513, and is fixed to the third frame body 513 via a support member (a member corresponding to the support member 551). The fourth driving means 524 is arranged at the center position of the hole 544 formed in the fourth frame body 514, and is fixed to the fourth frame body 514 via a support member (a member corresponding to the support member 551). The first to fourth driving means 521, 522, 523, 524 are, for example, motors having a rotating shaft extending upward.

  As indicated by arrows A3 and A4 shown in FIG. 13, the moving unit 5C can send air toward the lower side of the main body 3A. Specifically, the first to fourth propellers 531, 532, 533, 534 are rotated by the driving force transmitted from the respective rotary shafts of the first to fourth driving means 521, 522, 523, 524, and the main body 3A is rotated. Air can be sent downward.

Increase the drive output of. As a result, the rotation speeds of the third propeller 533 and the fourth propeller 534 arranged on both sides of the rear portion of the base 35 increase. Then, the amount of air blown in the rear portion of the base portion 35 increases. Then, since the moving means 5C is attached to the leg portion 36 of the main body 3A, the air cushion machine toy 2C tilts the main body 3A and the moving means 5C to move forward.

  When the air cushion machine toy 2C moves backward from the floating state, the drive circuit 72 raises the drive output of the first drive means 521 and the second drive means 522 based on the control signal generated by the control circuit 71. Let When the air cushion machine toy 2C moves from the floating state to the left, the drive circuit 72 operates the second drive means 522 and the fourth drive means 524 based on the control signal generated by the control circuit 71. Increase the drive output. Further, when the air cushion machine toy 2C advances from the floating state to the left, the drive circuit 72 operates the first drive means 521 and the third drive means 523 based on the control signal generated by the control circuit 71. Increase the drive output. Then, the air cushion machine toy 2C moves while tilting the main body 3A and the moving means 5C when moving backward, moving leftward, and moving rightward.

  At this time, the buffer portion 6 connects each of the first to fourth frame bodies 511, 512, 513, 514 and the skirt portion 4A. Further, the buffer portion 6 is an elastic body having elasticity such as rubber or vinyl, and suppresses the inclination of the moving means 5C from being transmitted to the skirt portion 4A. Therefore, when the air cushion machine toy 2C moves while tilting the main body 3A and the moving means 5C, the tilt of the moving means 5C is suppressed from being transmitted to the skirt portion 4A. Therefore, it is possible to prevent the gap 29 between the skirt portion 4A and the ground surface 28 from becoming uneven, and prevent the amount of air flowing out of the skirt portion 4A from becoming uneven. Therefore, it is possible to prevent the air cushion machine toy 2C from floating and moving instability. As a result, the air cushion machine toy 2C according to the present embodiment can move stably in any direction. Further, the operator can easily remotely control the air cushion machine toy 2C. Also, with regard to other effects, the same effects as those of the air cushion machine toy 2 described above with reference to FIGS. 1 to 8 can be obtained.

FIG. 14: is sectional drawing showing the 1st modification of the buffer part of this embodiment.
Note that FIG. 14 corresponds to a cross-sectional view taken along the section line BB shown in FIG.

  Similar to the cushioning portion 6A described above with reference to FIGS. 9 and 10, the cushioning portion 6A of the present modification is formed of a resin or metal having a property harder than the elastic body, instead of the elastic body, and has a ball joint structure. In this respect, the buffer section 6A of the present modification example is different from the buffer section 6 described above with reference to FIG. The buffer portion 6A is held by the holding portion 41 provided on the skirt portion 4A at a substantially central portion of the skirt portion 4A.

  As shown in FIG. 14, the first driving means 521A of the present modification is connected to the ball stud of the buffer portion 6A in the socket provided at the center, and is attached to the skirt portion 4A via the buffer portion 6A. There is. That is, the buffer portion 6A connects the first drive means 521A and the skirt portion 4A at the center position of the first propeller 531 and the first drive means 521A, and suppresses the inclination of the moving means 5C from being transmitted to the skirt portion 4A. .. The structure in which the buffer portion 6A connects the first drive means 521A and the skirt portion 4A is the same in the second to fourth drive means.

  In this modification, the buffer 6A may have a socket and the first to fourth driving means may have ball studs. That is, the first to fourth driving means of this modification may be attached to the skirt portion 4A via the buffer portion 6A having the ball joint structure. The other structure is the same as the structure of the air cushion machine toy described above with reference to FIGS. 12 and 13.

  According to this modification, since the cushioning portion 6A has the ball joint structure, when the air cushion machine toy moves while tilting the main body 3A and the moving means 5C, the inclination of the moving means 5C is not transmitted to the skirt portion 4A. Suppressed. Therefore, the gap 29 between the skirt portion 4A and the ground 28 can be prevented from becoming nonuniform, and the amount of air flowing out of the skirt portion 4A can be suppressed from becoming nonuniform. As a result, the same effects as those of the air cushion machine toy described above with reference to FIGS. 12 and 13 can be obtained.

  Further, as compared with the cushioning portion 6 described above with reference to FIGS. 12 and 13, the cushioning portion 6A of the present modification connects each of the first to fourth driving means and the skirt portion 4A in a narrow range. Therefore, the inclination of the moving means 5C can be suppressed from being transmitted to the skirt portion 4A, and the size of the buffer portion 6A can be suppressed. Thereby, the size of the main body 3A can be secured, and the flexibility of the shape and design of the main body 3A can be improved.

FIG. 15 is a cross-sectional view showing a second modified example of the buffer section of this embodiment.
Note that FIG. 15 corresponds to a cross-sectional view taken along the cross section BB shown in FIG. 11.

  In the present modification, the buffer section 6D has a ball joint structure 61 and an elastic body 62. The ball joint structure 61 is similar to the buffer portion 6A of the ball joint structure described above with reference to FIG. The elastic body 62 is provided between the moving means 5C and the skirt portion 4A, and connects the moving means 5C and the skirt portion 4A. Specifically, the skirt portion 4A is attached to the lower peripheral portions of the first to fourth frame bodies 511, 512, 513, 514 via the elastic body 62. The elastic body 62 is, for example, a coil spring. Alternatively, the elastic body 62 may be elastic, such as rubber or vinyl. Further, the elastic body 62 may have a bellows structure. That is, the present modification has a structure in which the buffer section 6 described above with reference to FIG. 13 and the buffer section 6A described above with reference to FIG. 14 are combined.

  According to this modification, the moving means 5C is stably supported by the skirt portion 4A via the buffer portion 6D. Therefore, the air cushion machine toy 2C can prevent the moving means 5C from inclining excessively even when it contacts an obstacle such as a wall, and can more stably move or turn. You can

  The air cushion machine toy 2C according to the present embodiment does not tilt the main body 3A and the moving means 5C in the floating and stationary state, but tilts the main body 3A and the moving means 5C when moving. However, the air cushion machine toy 2C is not limited to this, and the moving means 5C may be tilted and fixed in advance by, for example, a servo or the like to proceed. In other words, the moving means 5C may be tilted and fixed in advance by a servo or the like. Further, the moving means 5C may be capable of changing the tilt angle stepwise by a servo or the like, and may be fixed at a predetermined tilt angle during the progress. Even in this case, the same effects as those described above with reference to FIGS. 12 and 13 can be obtained.

Next, a third embodiment of the present invention will be described with reference to FIGS.
When the components of the air cushion machine toy of the third embodiment of the present invention shown in FIGS. 16 and 17 are the same as the components of the air cushion machine toy according to the first embodiment described above with reference to FIGS. 1 to 8. In the following, redundant description will be omitted as appropriate, and differences will be mainly described below.

  FIG. 16 is a perspective view showing an air cushion machine toy according to the third embodiment of the present invention. FIG. 17 is a front view of the air cushion machine toy as viewed in the direction of the arrow R shown in FIG.

  An air cushion machine toy 2D according to the third embodiment of the present invention shown in FIG. 16 includes a main body 3B, a skirt portion 4B, and a moving means 5D, and floats and moves the machine body using the air cushion. The main body 3B has an upper body 38 and four leg portions 36. The skirt portion 4 </ b> B has a base portion 42 and four, for example, a ring-shaped skirt portion main body 43, and has a structure in which the four skirt portion main bodies 43 are integrated with each other via the base portion 42. That is, the four skirt portion main bodies 43 are connected to each other via the base portion 42.

  Each moving means 5D is fixed to the main body 3B by using the leg portion 36, and each moving means 5D and the main body 3B are integrated with each other. The fixing structure of the moving means 5D will be described in detail. The legs 36 are provided on both sides of the front portion of the upper body 38 of the main body 3B and on both sides of the rear portion of the upper body 38. That is, the inner ends of the legs 36 are fixed to the four corners of the upper body 38, and each leg 36 extends toward the outside of the upper body 38. Moreover, the middle of each leg 36 is formed by being slightly bent, so that the outer end of each leg 36 is held horizontally, and the outer end of each leg 36 has a corresponding skirt. It reaches the central position of the space inside the part main body 43.

  As shown in FIG. 16, each moving unit 5D is attached to the outer end of each leg 36. That is, the moving means 5D is directly fixed to the outer end portion of the leg portion 36, without interposing another member such as a buffer portion. Specifically, the moving means 5D has first to fourth driving means 521, 522, 523, 524 and first to fourth propellers 531, 532, 533, 534. The first to fourth driving means 521, 522, 523, 524 are located at the center position of the space inside the corresponding skirt portion main body 43. The pitch angles of the first to fourth propellers 531, 532, 533, and 534 are fixed, and the first to fourth propellers 531, 532, 533, and 534 are located above the corresponding skirt portion main body 43. .. Thereby, the skirt portion 4B (specifically, the skirt portion main body 43) forms a space for accumulating the air sent by the rotation of the first to fourth propellers 531, 532, 533, and 534.

Next, a structural example of the main body 3B will be described. In the main body 3B shown in FIG. 16, each moving means 5D is fixed by using the leg portion 36, as already described. Moreover, the main body 3B has the upper body 38 and the control unit 7.
The upper body 38 shown in FIGS. 16 and 17 is, for example, a case made of plastic, which is a substantially rectangular parallelepiped case that is long in the front-rear direction and slightly short in the left-right direction. In the upper body 38, for example, the control unit 7 as shown in FIG. 7 is housed.

  The base portion 42 is shown by a broken line in FIG. 16 and is shown by a solid line in FIG. The base 42 is, for example, a plate member made of metal or plastic. The base portion 42 is a connecting member of the skirt portion body 43 for connecting the inner portions of the four skirt portion bodies 43 facing each other using a fixing means such as an adhesive. That is, the base portion 42 is an integrated member for integrally strengthening the four skirt portion main bodies 43 by strengthening them.

  As shown in FIG. 16, the base portion 42 has four substantially 1/4 circular recess portions 42R, and each recess portion 42R has a shape corresponding to the shape of the inner peripheral portion of the corresponding skirt portion main body 43. Has been formed. This prevents a part of the base portion 42 from protruding from the inner peripheral portion of the skirt portion main body 43 to the moving means 5D side. Accordingly, the skirt portion 4B (specifically, the skirt portion main body 43) secures a space for storing the air sent by the rotation of the first to fourth propellers 531, 532, 533, and 534.

  As shown in FIGS. 17 and 16, a cushioning material 6B is provided between the upper body 38 of the main body 3B and the base portion 42 of the skirt portion 4B. The upper end of the cushioning material 6B is fixed to the upper body 38, and the lower end of the cushioning material 6B is fixed to the base portion 42. As the cushioning material 6B, for example, a bellows structure made of metal, plastic, or rubber, or a coil spring made of metal or plastic is used.

  When the operator turns on the power switch of the air cushion machine toy 2D, the control unit 7 drives the first to fourth drive means 521, 522, 523, and 524 with the same drive output. As a result, the first to fourth propellers 531, 532, 533, and 534 rotate at the same speed as each other and send air toward the lower side of the main body 3, so that as shown in FIG. Is in a state of being levitated from the ground 28 at the position where the main body 3B is stopped.

  At this time, the first propeller 531 and the fourth propeller 534 arranged on one diagonal line shown in FIG. 16 and the second propeller 532 and the third propeller 533 arranged on the other diagonal line are opposite to each other. Rotate at the same speed. Therefore, the reaction due to the rotation of the first to fourth propellers 531, 532, 533, 534 cancels each other. Therefore, the main body 3 of the air cushion machine toy 2 floats above the ground at the stopped position without turning left and right.

  Next, when the operator advances the air cushion machine toy 2D from the levitated state, the rotational speeds of the third propeller 533 and the fourth propeller 534 arranged on the rear side increase. As a result, the moving means 5D fixed to the main body 3B tilts forward with the main body 3B. When the moving means 5D moves forward, the forward force is transmitted from the moving means 5D to the main body 3B. In this way, the air cushion machine toy 2 can move forward from the state where the main body 3B is levitated.

  When the air cushion machine toy 2D moves backward from the floating state, the rotational speeds of the first propeller 531 and the second propeller 532 arranged on the front side increase. Further, when the air cushion machine toy 2D advances from the floating state to the left, the rotation speeds of the second propeller 532 and the fourth propeller 534 increase. Further, when the air cushion machine toy 2D advances from the floating state to the right, the rotation speeds of the first propeller 531 and the third propeller 533 increase.

  By the way, the moving means 5D and the upper body 38 of the main body 3B are connected and integrated with each other using the leg portions 36. Further, the base portion 42 and the four skirt portion main bodies 43 are integrated with each other. The upper body 38 of the main body 3B and the base 42 of the skirt portion 4B are connected by a buffer material 6B such as a coil spring or a bellows member.

  Therefore, the unit composed of the moving means 5D and the main body 3B moves forward, moves backward, or moves leftward with respect to the unit (skirt portion 4B) composed of the base portion 42 and the four skirt body portions 43. , And when moving to the right, they are moved while being relatively inclined. The moving force is transmitted from the moving means 5D and the main body 3B to the base portion 42 and the four skirt portion main bodies 43 via the buffer portion 6B, so that the air cushion machine toy 2 floats the main body 3. It moves backward from the state, goes to the left, and goes to the right.

  Here, as described above, the unit of the moving means 5D and the main body 3B moves relative to the unit of the base portion 42 and the four skirt portion main bodies 43 (the skirt portion 4B) by inclining and moving relative to each other. The moving force of the cushion machine toy 2D is transmitted to the skirt portion 4B. Therefore, for example, when the moving means is directly fixed to the skirt portion via the main body and the cushioning portion 6B is not provided, the air cushion machine toy is moved (progressed) while tilting the whole. Then, the gap between the skirt portion and the ground or the water surface becomes uneven in the peripheral portion of the lower portion of the main body, and the amount of air flowing out of the air cushion machine toy through the gap may become uneven. is there. Then, the air cushion machine toy may become unstable in its floating and moving.

  On the other hand, the air cushion machine toy 2D according to the third embodiment of the present invention includes the cushioning portion 6B. The buffer portion 6B is an elastic body, and suppresses the inclination of the moving means 5D and the main body 3B from being transmitted to the base portion 42 and the four skirt portion main bodies 43. Therefore, the gap between the skirt portion 4B and the ground can be prevented from becoming uneven, and the amount of air flowing out of the air cushion machine toy 2D can be prevented from becoming uneven. Therefore, it is possible to prevent the floating and movement of the air cushion machine toy 2D from becoming unstable. This allows the air cushion machine toy 2D to move stably in any direction. Further, the operator can easily remotely control the air cushion machine toy 2D.

  Further, since the buffer portion 6B is formed of an elastic body such as a coil spring or an elastic body such as a bellows member, the inclination of the moving means 5D and the main body 3B can be adjusted by the relatively simple structure of the buffer portion 6B. And can be suppressed from being transmitted to the four skirt portion main bodies 43.

  The air cushion machine toy 2D can not only move from the floating state to the front, rear, left, and right, but can also turn left and right from the floating state. When turning the air cushion machine toy 2 from the levitated state to the right, the operator increases the drive output of the second drive means 522 and the third drive means 523. As a result, the rotational speeds of the second propeller 532 and the third propeller 533 arranged on the other diagonal line increase.

  Since the second propeller 532 and the third propeller 533 rotate in the same leftward direction as each other, when the rotational speed of the second propeller 532 and the third propeller 533 increases, a force for turning the moving means main body 51 to the right is generated. .. As a result, the moving means 5D turns to the right. Further, when the air cushion machine toy 2 turns to the left from the floating state, the drive output of the first drive means 521 and the fourth drive means 524 is increased.

  In this way, the air cushion machine toy 2D according to the present embodiment can move in any direction. At this time, the buffer portion 6B suppresses the inclination of the moving means 5D and the main body 3B from being transmitted to the base portion 42 and the four skirt portion main bodies 43. Therefore, the air cushion machine toy 2 can move stably. Further, the operator can easily remotely control the air cushion machine toy 2.

  In addition, in the example shown in FIG. 16 and FIG. 17, one buffer 6B is provided, but the number of buffers 6B to be installed is not particularly limited. The number of the buffers 6B installed may be, for example, two or three. In this way, when the plurality of buffer portions 6B are provided, the followability of the skirt portion 4B with respect to the main body 3B can be further enhanced.

Next, with reference to FIG. 18, a first modification example of the third embodiment of the present invention will be described.
FIG. 18 shows a first modification of the third embodiment of the present invention.
The buffer 6C of the first modification of the third embodiment of FIG. 18 is different from the buffer 6B of the third embodiment of FIG. The cushioning portion 6C of this modified example shown in FIG. 18 is not formed of an elastic body but is formed of resin or metal having a property harder than the elastic body, and has a ball joint structure. For example, the buffer portion 6A has a ball stud having a ball portion. The cushioning portion 6C includes a spherical socket 38A provided inside the upper body 38 and a ball stud 55.

For example, the ball stud 55 is vertically fixed from the base portion 42 and fixed. The ball 59 of the ball stud 55 is attached to the socket 38A. That is, the buffer portion 6C includes a unit including the upper body 38 of the main body 3B and the four moving means 5D at the center of gravity of the moving means 5B, a unit including the base portion 42 and the four skirt portion bodies 43 (skirt portion 4B), Are connected. As a result, the cushioning portion 6C suppresses the inclination of the moving means 5D and the main body 3B from being transmitted to the base portion 42 and the four skirt portion main bodies 43.
In this modification, the ball stud 55 may be attached to the upper body 38 side and the socket 38A may be provided on the base portion 42 side.

The moving means 5D and the main body 3B of this modified example move while being inclined with respect to the base 42 and the four skirt body 43, and transmit the moving force. As a result, the air cushion machine toy 2D advances from the levitated state, moves backward, moves to the left, or moves to the right.
According to this modification, since the cushioning portion 6C has the ball joint structure, the moving unit 5D tilts or rotates around the cushioning portion 6C. Therefore, it is possible to prevent the gap between the skirt portion 4B and the ground from becoming nonuniform, and prevent the amount of air flowing out of the air cushion machine toy 2D from becoming nonuniform. As a result, the same effects as those of the air cushion machine toy 2 described above with reference to FIGS. 1 to 8 can be obtained.

  Further, compared to the cushioning portion 6B shown in FIG. 17, the cushioning portion 6C of the present modified example has a unit of the main body 3B and four moving means 5D, a base portion 42 and four skirt portion main bodies 43 in a narrower range. And the unit (skirt portion 4B) can be connected. Therefore, the inclination of the moving means 5D and the main body 3B can be prevented from being transmitted to the base portion 42 and the four skirt portion main bodies 43, and the size of the buffer portion 6C can be reduced. Thereby, the size of the main body 3B can be ensured, and the flexibility of the shape and design of the main body 3B can be improved.

FIG. 19 shows a second modification of the third embodiment of the present invention.
In the present modification, the cushioning portion 6E has a socket 38A, a ball stud 55, a ball 59, and an elastic body 62. Socket 38A, ball stud 55 and ball 59 are as described above with respect to FIG.

  The elastic body 62 is provided between the upper body 38 of the main body 3B and the base portion 42 of the skirt portion 4B and connects the unit of the base portion 42 and the four skirt portion main bodies 43 (skirt portion 4B). There is. The elastic body 62 is, for example, a coil spring. Alternatively, the elastic body 62 may be elastic, such as rubber or vinyl. Further, the elastic body 62 may have a bellows structure. That is, this modification has a structure in which the cushioning portion 6B described above with reference to FIG. 17 and the cushioning portion 6C described above with respect to FIG. 18 are combined.

  In the example shown in FIG. 19, the buffer section 6E has a plurality of elastic bodies 62. In this case, it is preferable that the socket 38A, the ball stud 55, and the ball 59 are provided at the central position of the main body 3B, and the plurality of elastic bodies 62 are provided around the socket 38A, the ball stud 55, and the ball 59.

  According to this modification, the main body 3B is stably supported by the skirt portion 4B via the buffer portion 6E. Therefore, even if the air cushion machine toy 2D contacts an obstacle such as a wall, the moving means 5D can be prevented from inclining excessively, and the air cushion machine toy 2D can move more stably or turn. You can Further, as shown in FIG. 19, when the plurality of elastic bodies 62 are provided, the followability of the skirt portion 4B with respect to the main body 3B can be further enhanced.
