Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a toy having a rotating body.

[0002]

2. Description of the Related Art There is a conventional toy, for example, a windmill having various shapes and colors. This windmill can be rotated by the action of the wind or by a person blowing, and can enjoy watching it.

[0003]

However, in the case of the above-mentioned conventional wind turbine, only two types of rotation state and rotation stop state can be selected at a fixed position, and there is little change. For this reason, there is room for improvement.

The present invention is an improvement over the conventional wind turbine, which can be rotated at the time of blowing the air flow, can move upward to a different position in accordance with a change in the blowing amount of the air flow, has a good appearance, and is fun. It is an object of the present invention to provide a toy having a rotating body capable of increasing the weight.

[0005]

A toy having a rotating body according to the present invention has a rotating body having a center hole penetrating vertically and a wing provided on an outer peripheral portion, and is inserted into the rotating body with the center hole. A guide shaft for holding the rotating body so as to be rotatable and vertically movable, and an air blow port and an air blow port formed at one end and the other end, and a part of the guide shaft is coaxial with the air blow port. And a ventilating means for guiding the airflow from the venting pipe to the rotating body.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The rotating body has a center hole inserted into a guide shaft so as to be rotatable and vertically movable, and a blade provided on an outer peripheral portion.

The rotating body rises in accordance with the strength of the airflow blown out from the air outlet of the ventilation pipe, rises along the guide shaft, and rotates by the airflow acting on the blades. The rotating body descends along the guide shaft by stopping the air flow from the air outlet of the ventilation pipe or weakening the air flow, and returns to the original position.

The rotating body may be a hollow body or a body having a body made of a foam. In this case, the weight of the rotating body can be reduced, and the rotating body easily rises and rises with a relatively small air flow rate. As a foam,
For example, foamed plastic can be used.

[0009] The rotating body may have a main body forming a spherical, inverted conical or inverted pyramidal bottom for guiding the air flow from the air outlet of the ventilation pipe to the blade. In this case, it is easy to lift and rise with a relatively small air flow rate, to easily guide the air flow from the air blowing port to the blade, and to promote the rotating action of the rotating body by the blade. As the rotator, for example, those having an outer peripheral surface colored with various colors or having a pattern, a pattern, a character, a symbol, or the like can be used. In this case, the appearance can be improved.

[0010] As the blade, a plurality of blades provided at equal intervals around the outer peripheral portion of the rotating main body can be used. For example, it is preferable to use a blade that is inclined in a direction in which a tip side extending from a root side of the blade is suspended with respect to a line orthogonal to a center hole of the rotating body. The reason for this is that when the airflow blown from the air outlet of the ventilation pipe toward the bottom of the rotating body is guided to the blade along the bottom, in addition to the action force to rotate the blade, it rises and rises against the blade. This is because it can also be used as an acting force .

The cross-sectional shape of the blade may be, for example, a concave depression, a substantially U-shaped depression, a U-shaped depression, a V-shaped depression, or an arc-shaped depression when viewed from the front end side in the longitudinal direction.

The outer peripheral surface of the blade can be colored in various colors, and the color of the material used as the guide shaft can be used as it is.

The guide shaft may have a pedestal at one end. In this case, when using a toy having a rotating body, the operator can easily hold the pedestal by hand and use it with the pedestal placed in a fixed position.

As the guide shaft, for example, a thin wire made of metal or resin, a small-diameter rod, or the like can be used. The outer peripheral surface of the guide shaft can be colored in various colors, or the color of the material used as the guide shaft can be used as it is.

The vent pipe may have a bent portion between the air blow port and the air blow port for converting an air flow introduced from the air blow port into an upward flow toward the air blow port. it can. In this case, the air outlet can be opened on the extension line at a substantially horizontal position, and the air outlet can be opened on the same axis as the guide shaft (almost on a vertical line). For this reason, the ventilation pipe rises in the vertical direction along the guide shaft while the rotating body rotates, due to the air flow blown by the operator holding the air outlet port side in a substantially horizontal state with the mouth, and rises. It can be visually recognized that the condition is good.

[0016] The bent portion of the ventilation pipe may have an angle of 70 ° to 11 °.
It can be in the range of 0 °. In this case, the positional relationship between the air blowing port and the air blowing port of the ventilation pipe can be variously selected according to the purpose within the above-described range, and the most easy-to-use usage mode according to the preference of each operator. can get.

As the ventilation pipe, a pipe made of metal, nonmetal, resin or the like can be used. When a material having high rigidity is used as the ventilation pipe, a part of the guide shaft is integrally connected, so that a pedestal portion is not required at one end of the guide shaft. As the ventilation pipe, for example, a commonly used straw can be used. In this case,
A pedestal is provided at one end of the guide shaft to stably use the guide shaft.

[0018] The vent pipe may have a sound generating section for generating a sound. In this case, a sound can be generated according to the strength of the air flow blown from the air blowing port, the amount of the air flow, and the like, and the enjoyment of listening can be enjoyed.

The pedestal includes a bottomed tubular body, a lid member for closing an upper opening of the bottomed tubular body, a pedestal housed in the bottomed tubular body and connected to one end (lower end) of a guide shaft. Can be configured.
