Description

  The present invention relates to a toy for a yacht, and more particularly to a toy that can fold its sail.

  It is common for yachts and sailing ships that actually exist to have sails when sailing and fold sails when anchored. Sail expansion and contraction is usually done manually or by winding and releasing the winch.

  As for radio-controlled yacht toys, yacht toys that open and close the sail have already been proposed.

  For example, Patent Document 1 proposes a technique for shortening a sailboat by changing the length of a mast.

  Patent document 1 consists of several telescopic pipes with sail coverings covering the entire vertical space between the cross beams held by the cross beams, each cross beam being attached to each other by a vertical pivot shaft, A wing-type sail that consists of several horizontal cross-beam sections that correspond to a symmetrical wing-type sail, and each cross-beam can be rotated by a motor-controlled drive so that it can bend optimally for wind conditions. Is disclosed.

JP-A-5-139378

  However, although the winged sail described in Patent Document 1 reduces the shape of the sail, it is difficult to completely eliminate the sail. The height of the sail depends on the height of the cross beam. For this reason, as long as the height of the cross beam exists, the sail of the same height cannot be folded.

  In addition, even in the already proposed radio-controlled yacht toys, since the sail can not be adjusted because the sail height cannot be adjusted, the sail is susceptible to wind resistance, and the pilot controls the main body. It was difficult. This was because the sail could not be raised or lowered from the top to the bottom of the mast.

  Furthermore, since the actual ship is made of canvas, it can be completely folded. However, in a toy, it is cumbersome and impractical to provide a manual work or a small winch and fold it every time it is used.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a yacht toy that can be folded completely and without complicated work without leaving some sails when folded.

  A yacht-type toy according to the first aspect of the present invention includes a mast that is vertically installed on a hull, left and right side stays that support the mast by pulling the mast and fixing the mast, and the mast A back stay that is supported by being fixed to the hull by pulling from a forehead, a fore stay suspended from the mast, a jib seat attached to a jib boom suspended from the fore stay, and a lower end of the mast for rotation. A yacht-type toy comprising a main boom and a main sail attached to the main boom, the jib seat and the main sail are suspended from the upper part and lifted from the upper end of the mast to the lower end of the mast. A sail lift is provided.

  In addition, the sail elevating unit is connected to a rotation drive unit built in the hull, and is rotatably connected to the rotation unit of the rotation drive unit. A spiral screw shaft, an opening mast portion in which the spiral screw shaft is incorporated and opened on one surface thereof, a slider portion in which the opening mast portion is accommodated and a locking portion projects toward the opening mast portion, and the slider A jib seat suspension part provided at one end of the part and a main sail suspension part provided at the other end of the slider part, and rotating the spiral screw shaft by the rotation of the rotational drive part, The jib seat and the main sail may be moved up and down by driving.

  Furthermore, the sail elevating unit includes a rotation driving unit built in the hull, a first winding unit rotated by the rotation driving unit, and a first yarn unit whose lower end is wound by the first winding unit. A first yarn portion that changes its direction and is arranged at the top of the mast portion, a slider portion that is coupled to the first yarn portion at the upper end, and a lower end of the slider portion. A second yarn portion; a second winding portion that winds up the second yarn portion; a jib seat suspension portion provided at one end of the slider portion; and a main sail suspension provided at the other end of the slider portion. A suspension portion is provided, and the first winding portion or the second winding portion is rotated by rotation of the rotation driving portion to drive the slider portion to raise and lower the jib seat and the main sail. Good.

  Note that the rotation drive unit may be controlled by a radio control device.

  The yacht toy of the present invention is configured as described above. For example, when it is difficult to control the yacht due to a strong wind, the sail can be shortened to avoid the influence of the wind.

  After that, when the wind strength becomes suitable for control, the sail can be opened and played using the wind force.

  On the other hand, even when the wind is completely unaffected and there is no wind effect, it is difficult to play using the sail, so you can play with the sail contracted. In this way, since the sail can be selected to be reduced or expanded according to the climate and environmental conditions of the day, you can enjoy a variety of ways to play with yacht toys.

On the other hand, the rotation drive unit 124 is connected to a receiver of a radio pilot not shown.

  Subsequently, the operation according to the present invention will be described with reference to FIGS.

  In FIG. 1, a signal for folding a sail is transmitted from a transmitter of a radio pilot (not shown) toward a receiver. When the receiver receives the signal and sends a signal that can supply power to the rotation drive unit, the rotation drive unit 124 rotates. Then, the spiral screw shaft 104 connected to the drive shaft of the rotation drive unit rotates.

  Then, on the back surface of the lid portion 112 that constitutes the slider portion 106 joined to the spiral screw shaft 104, three locking portions 132 project at a predetermined interval at the center. When the locking portion 132 rotates while being guided by the screw groove 102 of the spiral screw shaft 104, the lid portion 112 slides downward. Accordingly, the slider unit 106 is lowered. As the slider portion 106 is lowered, the jib seat holding portion 114 and the main sail suspension portion 116 are also lowered in conjunction with the circumferential portion 108 and the lid portion 112. Subsequently, the jib seat 18 is lowered according to the jib seat holding portion 114 and the main sail 22 is lowered according to the main sail suspension portion 116.

  Since the fore guide stay 76 penetrates the fore guide through hole 122 in the jib sheet 18 when descending, the jib sheet 18 descends without collapsing.

  Similarly, since the back guide stay 94 penetrates the back guide through hole 120 in the main sail 22, the main sail 22 descends without collapsing.

  This descent is terminated by stopping the transmission of a signal to fold the sail from the radio pilot transmitter toward the receiver. The lowered state is shown in FIG.

  Next, a case where the sail is extended will be described.

  In FIG. 4, a signal for expanding a sail is transmitted from a transmitter of a radio pilot (not shown) toward a receiver. When the receiver receives the signal and sends a signal enabling the power supply to the rotation drive unit, the rotation drive unit 124 rotates in the reverse direction to that of FIG. Then, the spiral screw shaft 104 connected to the drive shaft of the rotation drive unit rotates in the reverse direction.

  Subsequently, the three points of the engaging portion 132 on the back surface of the lid portion 112 constituting the slider portion 106 to be joined to the spiral screw shaft 104 are rotated in the reverse direction while being guided by the thread groove 102 of the spiral screw shaft 104, thereby the lid portion 112. Slides upward. Therefore, the slider part 106 raises. As the slider portion 106 is lifted, the jib seat holding portion 114 and the main sail suspension portion 116 are also raised in conjunction with the peripheral portion 108 and the lid portion 112. Subsequently, the jib seat 18 rises according to the jib seat holding portion 114, and the main sail 22 rises according to the main sail suspension portion 116.

  Since the fore guide stay 76 penetrates into the fore guide through hole 122 in the jib sheet 18 when it rises, the jib sheet 18 rises along the fore guide stay 76.

  Similarly, since the back guide stay 94 passes through the back guide through hole 120 in the main sail 22, the main sail 22 ascends along the back guide stay 94.

  By operating as described above, it is possible to completely fold without leaving some sails during folding and to fold without complicated work.

  In addition, by remote control by wireless control, the sail can be easily moved up and down even if the wind volume changes when the hull is in a remote location.

  A second embodiment of the yacht toy 2 according to the present invention is shown in FIG. The second embodiment is a yacht toy that uses a fixing band as a fixing method of the main sail. In particular, differences from the first embodiment will be described.
