Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The terms or words used in the specification and claims are not to be construed as limiting in a conventional or dictionary sense, but should be construed as meanings and concepts consistent with the technical spirit of the present invention. Therefore, the embodiments described in the specification and the drawings shown in the drawings are only the most preferred embodiment of the present invention, and do not represent all of the technical idea of the present invention, various modifications that can be replaced at the time of the present application It should be understood that there may be equivalents and variations.

  1 is a conceptual diagram illustrating a conventional variable surface display using individual actuators. Referring to FIG. 1, a conventional variable surface display uses a method of deforming a surface by pushing or pulling a plurality of unit units connected to a plurality of actuators, respectively. As the actuator, a technique using a pneumatic piston (US 7,277,080), a solenoid array (KR 2009-0103984), a piezoelectric element or the like is known. In particular, U.S. Patent No. 7,277,080 has a dynamic display by providing an array of actuators such as a pneumatic piston and a connection node in the lower portion of the screen formed of a metal triangle plate.

  However, the conventional method using the actuator has a disadvantage in that a plurality of actuators need to be installed as many as the number of unit units in order to increase the density of the unit unit, thus making it difficult to manufacture and increase the cost. In addition, due to the coupling with the actuator is not easy to remove and there is a limit that there is little interactive element due to the lack of interaction elements with the user.

In the present invention, even if a plurality of actuators are not individually connected to the unit unit, it is possible to form a three-dimensional physically deformed surface 940 by the linear cam 700 having a mole shape, and replaceable pins ( Disclosed is a variable surface display using a linear cam that can be extended to various play media and the like and interacts with a user by using 920 and 960.

  2 is a partial cross-sectional view of a variable surface display using a linear cam according to the present invention. Referring to FIGS. 2A and 2B, a mole shape is formed between a stage 600 and a lower end of a fin matrix 900 formed of a plurality of fins 920 perpendicular to the ground. A linear cam 700 is located.

When the stage head 500 moves to the right according to the displacement signal input by the user, the linear cam 700 synchronized by the magnetic force moves together, and the moving direction surface of the linear cam 700 is located at P ₂ . The pins are raised sequentially in the opposite direction of gravity. Subsequently, as the linear cam 700 moves further to the right, the pins pushed up are sequentially descended by gravity in the P ₁ portion, which is a surface opposite to the linear cam 700 in the direction of movement, and the mole in the ground It conveys a visual sense as the mole moves in the ground.

On the other hand, the plurality of pins 920 may be made of a pin having a predetermined height, preferably a hexagon pin having a hexagonal cross section. In addition, the pin matrix 900 may be formed by densifying each other without a separate fastening member. Unlike a conventional variable surface display, even if a plurality of actuators are not provided, the pins 920 may have a high density (or resolution), thereby providing smooth movement.

  A linear cam 700 is positioned below the pin matrix 900, and the linear cam 700 is placed on a stage 600 that can move in two dimensions. The shape of the linear cam 700 is preferably provided in a mole shape so that the outermost end can penetrate into the lower ends of the pins 920.

  The linear cam 700 of the present invention refers to converting a two-dimensional horizontal movement into a vertical movement of the pins 920. However, when the linear cam 700 moves vertically, A term that may include transmitting a vertical motion to the pins 920. For example, if the linear cam 700 has a structure in which the height or shape is variable, the physical movement of the pins 920 may be caused by the vertical position change of the linear cam even if there is no movement in the horizontal direction. That means you can pass it.

Since the pins 920 and the linear cam 700 are stacked without a separate fastening member, the pins 920 and the linear cam 700 may be replaced by changing shapes or sizes of the pins 920 and the linear cam 700. You may. In addition, the user can be used as a variety of play medium as an additional unit that can be replaced (this will be described later)

On the other hand, a magnetic force may be used as a means for moving the linear cam 700 placed on the stage 600 in synchronization with the horizontal direction. In more detail, a first magnetic 740 is provided inside the linear cam 700, and a stage head 500 positioned below the linear cam 700 and spaced a predetermined distance from each other is also a second magnetic. 540, the stage head 500 and the linear cam 700 may realize a synchronized movement by magnetic force. In the embodiment of the present invention, neodymium (Nd) magnets are used as the first magnetic 740 and the second magnetic 540. A method of driving the stage head 500 will be described later.

Although the inside of the pin 920 may be filled, it is preferable to use a pin having a hollow portion therein to reduce the overall weight of the structure. On the other hand, the maximum length of the pins 920 is not limited, but if the length is too short, the appropriate length because the pin may be pulled out by the shape of the linear cam 700 and the relative height difference with the linear cam 700.

Since one end of the linear cam 700 moves in the opposite direction to gravity while penetrating the lower ends of the pins 920, the lower ends of the pins 920 are provided in a round shape. In order to more effectively reduce the friction force between the pins 920 and the linear cam 700, a material having moderate elasticity, flexibility, and stretchable friction, such as spandex 820, is preferably used.
