Description

  The present invention relates to a non-ice curling stone capable of performing a curling competition in a flat place other than on ice.

Curling is a competition on ice, and the time and place where competitions can be performed are limited. For this reason, many people have the reality that even if they are interested in the competition, it is difficult to actually do it. In view of this, a playground equipment that can perform a game similar to a curling game in a flat place indoors or outdoors other than on ice has been proposed (Patent Document 1). There is also a game machine in which curling competition is turned into a game (Patent Document 2).

  The play equipment of patent document 1 is trying to make the movement close | similar to the movement of the curling stone on ice by attaching three casters to the lower part of a main body. However, although the caster can change its direction freely, in order to change the direction, a frictional resistance is generated between the caster and its ground contact surface, so this play equipment moves like a curling stone on ice. It doesn't move freely with little resistance from the competition surface (ice surface). For this reason, although the competition using the above-mentioned play equipment is similar to the curling competition, it is essentially regarded as a competition different from the curling competition.

  This invention aims to make it possible for anyone to perform curling competitions at a familiar place, and for this purpose, provides a non-ice curling stone that moves in the same way that an ice curling stone slides on ice. The challenge is to do.

  In response to the above problems, the present invention is configured as follows. That is, the non-ice curling stone according to the present invention has an outer shell body composed of a flat bottom plate and a dome-shaped cover having a lower end peripheral edge joined to the outer peripheral edge of the bottom plate, and the bottom plate is provided with the bottom plate. It is characterized in that a blower for forming compressed air discharge holes communicating with the spaces on both sides and sending the compressed air to the bottom plate side is provided inside the outer shell.

  When the blower is driven, the compressed air sent to the bottom plate side by the blower is discharged downward from the compressed air discharge hole. As a result, the stone is lifted from the flat surface on which the stone is placed. In this state, when a horizontal external force is applied to the stone, the stone slides while floating from the flat surface. At this time, since no frictional resistance is generated between the stone and the flat surface, the stone slides smoothly according to the external force. This movement is very similar to the movement of a curling stone on ice.

  When the planar shape of the outer shell is circular, the stone rotates well around the vertical center line of the outer shell. By adjusting the direction and speed of rotation, the course of the stone can be bent with respect to the run direction. For this reason, the movement of the stone becomes closer to the movement of the stone on the ice curling.

  If a handle for sliding operation is fixedly provided on the upper part of the outer shell body, it is possible to perform sliding with delicate force adjustment and easy to carry.

  The non-ice curling stone according to the present invention can be slid in a state where the compressed air is discharged downward from the compressed air discharge hole formed in the bottom plate of the outer shell body and floated from the flat surface. The movement is very close to the stone. Therefore, by using the non-ice curling stone of the present invention, it has become possible to perform a curling competition even in a place that is not on the ice.

  A preferred embodiment of the present invention is shown in FIGS. The non-ice curling stone 1 has an outer shell body 4 including a flat bottom plate 2 and a dome-shaped cover 3 having a lower end peripheral edge joined to an outer peripheral edge of the bottom plate 2. The planar shape of the outer shell body 4 is circular. A handle 5 for sliding operation is fixedly attached to the upper portion of the dome-shaped cover 3.

  The outer shell 4 has a hollow shape, and a blower 6 for sending compressed air to the bottom plate 2 side is accommodated therein. The blower 6 is driven by a motor 8 that rotates using a battery 7 as a power source. The blower 6, the battery 7 and the motor 8 are installed on a support plate 9 fixed inside the dome-shaped cover 3. A ventilation hole 10 is formed in the radially outer portion of the support plate 9 where the blower 6 or the like is not installed. The blower 6 is switched ON / OFF by a switch 11 provided on the handle 5. The blower 6 rotates about an axis 6a concentric with the vertical center line O of the outer shell body 4, and the battery 7 has a weight balance of the entire stone 1 that is substantially uniform in the circumferential direction about the vertical center line O. It is preferable to arrange a motor 8 or the like. Note that reference numeral 12 in FIG. 1 is a guide plate that guides the air to flow properly in the outer shell body 4.

  In the upper center of the dome-shaped cover 3, an intake port 13 for air supplied to the blower 6 is formed. A lattice-shaped protective cover 14 is attached to the air intake port 13. The bottom plate 2 is formed with discharge holes 15 for compressed air sent from the blower 6. The compressed air discharge hole 15 communicates the space on both sides of the bottom plate 2. A large number of compressed air discharge holes 15 are formed in the bottom plate 2, and, for example, as shown in FIG.

  The competition using the non-ice curling stone 1 is performed on a flat surface such as a gymnasium floor or a sports field. When the blower 6 is driven with the switch 11 turned ON, the air is taken in from the air intake port 13 by the blower 6 and is sent to the bottom plate 2 side as compressed air, and is downward from the compressed air discharge hole 15 of the bottom plate 2. Discharged. That is, an air flow as indicated by an arrow in FIG. 1 is generated. When the stone 1 is placed on the flat surface 16, the stone 1 is lifted from the flat surface 16 by the compressed air discharged from the compressed air discharge hole 15. Since the compressed air discharge holes 15 are arranged substantially evenly distributed over the entire surface of the bottom plate 2, the bottom plate 2 is held so as to be substantially parallel to the flat surface 16.

  In this state, when the handle 5 is grasped and an external force in the horizontal direction is applied to the stone 1, the stone 1 slides while being lifted from the flat surface 16. At this time, since no frictional resistance is generated between the stone and the flat surface 16, the stone 1 slides smoothly according to the external force. Further, the planar shape of the outer shell body 4 is circular, and the weight balance in the circumferential direction around the upper and lower center line O of the outer shell body 4 is substantially uniform. Is added, the stone 1 rotates well around the vertical center line O. Depending on the direction and speed of the rotation, the course of Stone 1 bends to the left and right with respect to the sliding direction. This movement is very similar to the movement of a curling stone on ice. Therefore, by using this non-ice curling stone 1, a curling competition that is very close to ice curling can be performed.

  The non-ice curling stone of the present invention is not limited to the above embodiment. The blower 6 and the compressed air discharge hole 15 can be arranged differently from the above embodiment. In some cases, the planar shape of the outer shell 4 may be non-circular. Further, the handle 5 may not be provided. The output of the blower 6 is preferably provided with output control means so that the number of rotations of the motor can be changed in consideration of the unevenness on the flat surface, and is made to correspond to the place where it is used. be able to. Moreover, if the inside of the dome-shaped cover 3 is divided into two and two fans are provided and the rotation directions of the fans are set in reverse, the stone 1 itself can be prevented from rotating itself, and a more stable floating state can be obtained. .

  Further, when the stone 1 according to the present invention is used on a desk or the like, when the stone 1 is pushed and advanced to the end of the desk, if a part of the main body protrudes, the compressed wind of the bottom plate 2 of the protruding part Since the air discharged downward from the discharge holes 15 is diffused as it is into the space around the desk, the buoyancy cannot be obtained and the air stops at the protruding position. For this reason, since the stone 1 can be moved on a limited desk, table, etc. without dropping, it can also be used as a play equipment for children that can realize a mysterious feeling floating due to buoyancy. it can.

It is sectional drawing of the stone for non-ice curling of this invention. FIG. It is the bottom view.
