And

  Symbols in parentheses indicate corresponding elements or corresponding matters described in the drawings and the best mode for carrying out the invention described later.

  According to the balloon structure of the first aspect of the present invention, the balloon main body, the deformed portion protruding from the balloon main body, the blower that continuously supplies air to the balloon main body, and the opening / closing operation of the valve Equipped with a supply valve that intermittently supplies air from the balloon body to the deformation part and a discharge valve that continuously discharges air from the deformation part, and discharges the amount of air per unit time supplied to the deformation part by the supply valve. The amount of air per unit time expelled from the deformed part into the atmosphere by the valve is set so that the deformed part can be erected by the supply of air accompanying the opening of the supply valve and the supply of air accompanying the closing of the supply valve Since it is bent by interruption, it is bent and deformed intermittently, so that failure and damage accidents are unlikely to occur. In addition, the manufacturing cost can be kept low.

  That is, since this balloon structure is not one that pulls and moves the string as in the prior art, the string does not get entangled, and therefore it is difficult for failure to occur. In addition, since a large and complicated device such as an internal structure or an actuator is not provided, the structure is simple. Therefore, failure is unlikely to occur, and damage accidents during transportation or after installation can be eliminated. Also, the manufacturing cost can be kept low.

  The intermittent bending deformation of the deforming portion is performed by supplying air to the deforming portion intermittently from the supply valve while continuously discharging the air from the discharging valve. That is, in the state in which air is supplied from the supply valve, the amount of air is larger than the amount of air discharged from the discharge valve, so that the deformed portion swells when its internal pressure rises to form a standing posture. Further, in a state where the supply of air from the supply valve is shut off, air is discharged from the discharge valve, so that the internal pressure of the deformed portion is reduced and the deformed portion is bent and deformed. At this time, air in the balloon body does not flow out, and new air is continuously supplied from the blower, so that a sufficient swelling can be maintained.

Further, according to the balloon structure of the second aspect, in addition to the function and effect of the invention of the first aspect, the supply valve includes a fixed valve portion having a flat plate shape and a fixed hole, and a disk shape. In this case, the entire structure is very simple and the strength is high. Therefore, failure is unlikely to occur, and damage accidents during transportation or after installation can be prevented.
Various shapes of the fixed hole formed in the fixed valve part and the movable hole formed in the rotary valve part, for example, as described in claim 3, one of the fixed hole and the movable hole is a circular hole. By making the other a substantially crescent-shaped long hole, the timing for supplying air to the deformable portion can be changed, and the bending deformation of the deformable portion can be varied.

  According to the balloon structure described in claim 4, in addition to the operational effects of the invention described in claim 2 or 3, both the fixed valve portion and the rotary valve portion are disk-shaped, and the rotary valve portion is a motor. Position that is fixed to the rotating shaft of the motor while being in sliding contact with the upper surface of the fixed valve portion fixed to the driving portion of the motor, and rotates with the rotation of the motor. Or the position where both do not overlap, the structure is simple.

  Further, according to the balloon structure of the fifth aspect, in addition to the function and effect of the invention of the first to fourth aspects, the elastic member is provided in the predetermined portion of the deformation portion. Large and stable.

  That is, since this elastic member contracts so as to bend the deformed portion in a predetermined direction due to pressure reduction caused by discharging air from the discharge valve, in addition to the natural contraction of the deformed portion, the deformable portion Large and always bendable stably in the same direction.

Further, according to the operation method of the balloon structure according to claim 6, the rotary valve portion is detachable with respect to the rotation shaft of the motor, and a plurality of rotations having different positions and shapes of the movement holes of the rotary valve portion are different. By appropriately selecting any one of the valve parts, the timing at which air passes through the moving hole and is supplied to the deformed part is determined, and the bending deformation of the deformed part is controlled. Can be given.
For example, if the rotary valve portion in which the moving hole is composed of one long hole is selected, the deformable portion can be subjected to one loose bending deformation while the rotary valve portion makes one rotation. If a material composed of two round holes is selected, fast bending deformation can be performed twice.

  A balloon structure 1 according to an embodiment of the present invention will be described with reference to FIGS. 1 to 4. FIG. 1 is a rear view showing the balloon structure 1.

Note that the blower 4 and the supply valve 10 are connected to a power source unit 7 such as a commercial power source, and are operated by electric power supplied from the power source unit 7.

  The balloon body 2 forms most of the outer shell (a portion excluding the deforming portion 3), and is made of a soft material such as cloth or vinyl that easily swells with air supplied by the blower 4.

  The deforming portion 3 forms a part of the outer shell (portion excluding the balloon main body 2) and is formed to protrude from the balloon main body 2. The deformed portion 3 can be easily formed in the same manner as the balloon main body 2 by the air supplied from the supply valve 10. Made of soft material such as swelling cloth or vinyl. In the present embodiment, the two ear portions of the rabbit are used as the deformable portion 3.

  The blower 4 is provided on the bottom surface portion of the balloon body 2 and continuously supplies air into the balloon body 2 and is constituted by a motor and a fan.

  The supply valve 10 is provided at a boundary portion between the balloon body 2 and the deformation portion 3 in a state where the boundary portion is closed, and intermittently supplies air from the balloon body 2 to the deformation portion 3 by opening and closing the valve. Is.

As shown in FIGS. 5 to 7, the supply valve 10 includes a fixed valve portion 12 and a rotary valve portion 13.
The fixed valve portion 12 has a disc shape and is inserted into a through-hole 12b formed in the center thereof so that the rotary shaft 11b protruding from the drive portion 11a of the motor 11 is rotatably inserted, and the lower surface of the fixed valve portion 12 of the drive portion 11a of the motor 11 is inserted. It is fixed at the top. Then, one fixed hole 12a having a circular hole through which air passes is formed at a position on the outer peripheral end side away from the center portion (position of the insertion hole 12b) of the fixed valve portion 12 (FIG. 7). reference). Here, the size of the fixing hole 12a and the size of the insertion hole 12b are the same.

  The rotary valve portion 13 is also in the shape of a disc disposed on the upper surface of the fixed valve portion 12 so as to be in sliding contact with the fixed valve portion 12, and the rotary shaft 11b of the motor 11 is fitted into the central portion of the rotary valve portion 13 so that the rotary shaft 11b is fitted. An assembly hole 13b to be fixed is formed. And the movement which made the substantially crescent-shaped long hole which makes the pressurized air from the fixed hole 12a pass intermittently in the position of the outer peripheral edge part side which removed from the center part (position of the assembly hole 13b) of the rotary valve part 13 One hole 13a is formed (see FIG. 6).

The rotary valve unit 13 moves between an open position for opening the supply valve 10 and a closed position for closing the supply valve 10 while rotating together with the rotary shaft 11 b by the motor 11. That is, as shown in FIG. 8A, the moving hole 13a overlaps with the fixed hole 12a of the fixed valve portion 12 and air is passed in the open position where the supply valve 10 is opened, and as shown in FIG. 8B. The state in which the air is shut off at the closed position where the supply valve 10 is closed without the moving hole 13a overlapping the fixed hole 12a of the fixed valve portion 12 is repeated.
At that time, the lower surface of the rotary valve portion 13 rotates while being in sliding contact with the upper surface of the fixed valve portion 12.
The nut 14 is screwed into and assembled with the rotary shaft 11b, and plays a role of preventing the rotary valve portion 13 from coming out of the rotary shaft 11b. The rotary valve portion 13 is detachably fixed to the rotary shaft 11b by the nut 14, and the rotary valve portion 13 can be easily detached from the rotary shaft 11b by loosening the nut 14.

  The shape of the rotary valve portion 13 is not limited. For example, as shown in FIG. 9A, a plurality (four in this case) of circular shapes (round holes) may be provided. As shown to (b), it can also comprise by mixing a long hole thing and a round hole thing.

The discharge valve 20 is provided in the deformation | transformation part 3, and discharges the air of the deformation | transformation part 3 continuously in air | atmosphere.
As shown in FIGS. 10 to 12, the discharge valve 20 is configured by fixing a disk-shaped fixing plate 21 and a rotating plate 22 in a state where they are overlapped with a countersunk screw 24 having a knob 23 and a female screw 25. is doing. The fixed plate 21 and the rotating plate 22 are formed with three through holes 21a and three hole portions 22a facing the outer peripheral end side, and as shown in FIG. By adjusting the overlap of the portions 22a, the amount of air discharged from the deformable portion 3 into the atmosphere is set. In addition, a fitting hole 21b and a through hole 22b for passing a countersunk screw 24 are formed in the center portions of the fixed plate 21 and the rotating plate 22, respectively.

FIG. 13A shows a state in which the through hole 21a of the fixed plate 21 and the hole 22a of the rotating plate 22 are completely overlapped. In this state, the largest amount of air can be discharged.
FIG. 13B shows a partially overlapped through hole 21a and hole 22a. In this state, the amount of air discharged can be reduced.
Furthermore, FIG.13 (c) shows the state which shifted the through-hole 21a and the hole 22a completely. In this state, the discharge of air from the discharge valve 20 can be stopped.
Adjustment of the overlapping degree of the through hole 21a and the hole 22a can be performed by turning the knob 23 to loosen the screw screw 24 and the female screw 25 and rotating the rotating plate 22 manually.

  In this balloon structure 1, the amount of air supplied for a short time from the supply valve 10 to the deformation unit 3 is sufficiently larger than the amount of air per unit time discharged to the atmosphere by the discharge valve 20. Is set. This setting can be performed by adjusting the size, shape, number, and the like of the fixed hole 12a and the moving hole 13a of the supply valve 10 and the through hole 21a and the hole 22a of the discharge valve 20. Further, the amount of air supplied from the blower 4 to the balloon body 2 is set to be sufficiently larger than the amount of air discharged from the discharge valve 20. This setting can be performed by adjusting the rotation speed of the fan of the blower 4.

  The elastic member 5 is formed of a stretchable rubber string piece, and is fixed to the front lower portion of the deformable portion 3 by sewing or bonding. The elastic member 5 contracts so as to bend the deformable portion 3 in the forward direction due to a decrease in air pressure. In addition, although this elastic member 5 is provided in the inner surface side of the deformation | transformation part 3, it can also be provided in the outer surface side. The elastic member 5 is not limited to a rubber string piece, and for example, springs such as a spiral spring can be used.

  The balloon structure 1 operates as follows. First, the air blower 4 is operated, and air is continuously supplied into the balloon body 2. As a result, the balloon body 2 swells when its internal pressure rises, forming a rabbit outline (excluding the ear portion).

Next, the supply valve 10 is operated. The supply valve 10 rotates in a state where the rotary shaft 11b of the motor 11 rotates, the rotary valve portion 13 rotates, and the moving hole 13a of the rotary valve portion 13 overlaps the fixed hole 12a of the fixed valve portion 12. The air in the main body 2 is supplied to the deforming portion 3 through the fixed hole 12a and the moving hole 13a.
When air is supplied to the deformable portion 3, its internal pressure rises and swells to form a standing posture. Thereby, as shown in FIG. 2, the ear of a rabbit stands up. At this time, the amount of air per short time supplied from the supply valve 10 to the deforming portion 3 is set to be larger than the amount of air per unit time discharged into the atmosphere by the discharge valve 20, so that the deforming portion 3 is easy. Inflates. In addition, since air is continuously supplied to the balloon body 2 by the blower 4, a sufficient amount of air can be supplied to the deformable portion 3 from the supply valve 10.

  From this state, when the rotation shaft 11b of the motor 11 and the rotation valve portion 13 are rotated, the movement hole 13a is displaced from the fixed hole 12a and the supply of air is stopped, the air in the deformation portion 3 is discharged from the discharge valve 20 into the atmosphere. As a result, the internal pressure decreases. As a result, the deformable portion 3 contracts and bends, and in addition, the elastic member 5 contracts, so that it is bent forward by the contracting force to form an inclined posture. Thereby, as shown in FIG. 3, the ear of a rabbit falls down. At this time, the air in the balloon main body 2 does not flow out to the deformable portion 3 and new air is supplied from the blower 4, so that the air can sufficiently expand and keep its outline normal.

  Subsequently, when the moving hole 13a again overlaps with the fixed hole 12a due to the rotation of the rotating shaft 11b of the motor 11, air is supplied to the deformable portion 3 to form an upright standing posture. By repeating such an operation, the deforming portion 3 intermittently forms a standing posture and a tilting posture alternately.

In the balloon structure 1 according to the present embodiment, the deformation portion 3 is bent and deformed by increasing / decreasing its internal pressure by the blower device 4, the supply valve 10 and the discharge valve 20, so that a failure hardly occurs.
That is, the supply valve 10 is provided at the boundary portion between the balloon body 2 and the deforming portion 3, and the discharge valve 20 is provided at the deforming portion 3. Is also expensive. In addition, there are no large devices such as internal structures or actuators. Therefore, failure is unlikely to occur, and damage accidents during transportation or after installation can be eliminated. Furthermore, since the structure is simple, manufacturing costs can be reduced.

  Moreover, since this balloon structure 1 is provided with the elastic member 5 made of rubber string pieces in the deformable portion 3, the bending deformation of the deformable portion 3 can be increased by the contraction force. Further, since the elastic member 5 always contracts in a predetermined direction, the bending deformation can be stabilized.

  Further, the balloon structure 1 according to the present embodiment is not limited to the one simulating the shape of a rabbit. For example, the one simulating an elephant as shown in FIG. 14 or the beckoning cat as shown in FIG. Can also be used.

In the model of an elephant, the nose part is the deforming part 3, the supply valve 10 is provided at the root part (the boundary part between the balloon body 2 and the deforming part 3), and the discharge valve 20 is provided near the tip, The nose is bent and deformed (FIG. 14 (a) shows a posture in which the deformable portion 3 stands and FIG. 14 (b) shows a bent posture).
Further, in the model of a beckoning cat, the hand is used as the deforming portion 3 and the supply valve 10 is provided at the base portion thereof, and the discharge valve 20 is provided near the tip thereof to give a beckoning action (FIG. 15 (a ) Shows a posture in which the deformable portion 3 stands, and FIG. 15B shows a bent posture).

  Since any balloon structure 1 is formed so as to be bent and deformed by increasing / decreasing the internal pressure of the deformable portion 3 without providing an internal structure, failure is unlikely to occur, and damage during transportation or after mounting Accidents can be eliminated. Moreover, since the structure is simple, the manufacturing cost is low.

  A method for operating the balloon structure 1 according to the embodiment of the present invention will be described. This operation method is to operate the balloon structure 1 according to the above embodiment, and by appropriately selecting one of the plurality of rotary valve parts 13 having different formation positions and shapes of the movement holes 13a, The timing of discharging the pressurized air from the moving hole 13a is determined, and the bending operation of the bending portion is controlled.

Thus, any movement can be given to the bent portion. For example, by selecting the rotary valve portion 13 in which the moving hole 13a is composed of one long hole, the deformable portion 3 can be subjected to one loose bending deformation within a unit time.
In addition, by selecting one made up of two or more round holes, fast bending deformation can be performed twice or more.

  The elastic member 5 contracts to bend and deform the deformable portion 3 in a predetermined direction when the deformable portion 3 is bent by shutting off the supply of air when the supply valve 10 is closed. Although provided in the predetermined part of the part 3, when the deformation | transformation part 3 deform | transforms by gravity by air supply interruption | blocking, it does not need to provide especially.
