  The display device of the present invention will be described below with reference to the accompanying drawings. The display device according to the present embodiment is installed in, for example, department stores, restaurants, pachinko stores, other stores and amusement halls, venues such as parties and events, and other various places, and is used for decoration, atmosphere creation, etc. It is. And it is an interesting display apparatus which can see and enjoy the movement of the floating body which floats by a unique movement within the regulation frame while floating the floating body by the upflow generator. 1 to 5 show an embodiment of a display device of the present invention. As shown in FIGS. 1 and 2, in the present embodiment, the display device 10 includes an upflow generator 12, a floating body 14, and a restriction frame 16.

  In this embodiment, it has the base 18 which supports the display apparatus 10 whole. The base 18 is made of, for example, a metal hollow cylindrical tubular member having a certain degree of strength, and is arranged with the axial direction directed vertically. A plurality of communication gaps 19 are provided on the cylindrical peripheral surface of the base 18 so that the hollow interior communicates with the outside. In the present embodiment, the display device 10 can be stably placed on a flat surface such as a floor surface, a base surface, or a shelf, for example, via the base 18, and can be installed independently on the installation site. be able to. The base 18 is not limited to a cylindrical shape, and may be, for example, a rectangular tube, a polygonal tube, a cylindrical shape of any other shape, a box shape, a frame configuration, or any other arbitrary configuration. It is preferable to adopt an embodiment that can be arranged in a state in which they are placed. In the present embodiment, the upflow generator 12 and the restriction frame 16 are integrally assembled to the base 18.

  In this embodiment, as shown in FIGS. 1, 4, and 6, the upward flow generation device 12 is upward flow generation means that generates upward flow F by ejecting air upward from the ejection portion 21. Further, the upward flow generating device 12 as the upward flow generating means is a floating means for generating the upward flow F and floating the floating body 14 as described later. In the present embodiment, the upward flow generation device 12 includes a blower fan 20 and a direct current cylinder portion 22. The blower fan 20 is composed of, for example, a propeller fan that rotates a plurality of propeller blades attached in the radial direction around the rotation axis to send air mainly in the rotation axis direction. To the 100V power supply. In the present embodiment, the blower fan 20 has a frame fixed to the base 18 with the rotation axis directed in the vertical direction on the upper end side of the cylindrical base 18, and from the bottom upward when the fan is rotating. It is designed to send an almost constant amount of wind toward the sea. At this time, the blower fan 20 is supplied with air from the outside through the communication gap 19 of the base 18.

  The direct current cylinder part 22 ejects the wind generated by the blower fan 20 as a substantially direct current upward flow F. In other words, in the present embodiment, the upward flow of the direct current cylinder portion 22 reduces the dispersion in the lateral direction, and the air is ejected substantially vertically upward. In the present embodiment, as shown in FIGS. 4 and 5, the direct current cylinder portion 22 is disposed in the immediate vicinity of the blower fan 20 to divide the flow of wind from the blower fan 20 and to It includes a plurality of small divided cylindrical members 24 provided with an outlet 24a facing upward. In the present embodiment, the DC cylinder portion 22 has seven small divided cylindrical members 24 having the same length and size, with the axial direction aligned in the vertical direction, and is arranged around one cylindrical member in plan view. However, the other cylindrical members are provided in a bundled state so as to be arranged in an axially symmetrical manner, and are fixed on the blower fan 20. The jet outlets 24a of the plurality of small divided cylindrical members 24 gather to form the jet part 21 of the upflow generator 12 in which the horizontal cross section of the range through which the upflow flows approximates a circle. By dividing the wind generated in the blower fan 20 by a plurality of small divided cylindrical members 24 in a flow passage having a small cross-sectional area, the wind speed is increased in each small divided cylindrical member 24 and the dispersion in the lateral direction is reduced. The generation of a direct current upward flow can be expected. Therefore, the range in which the upward flow as a whole ejected from the ejection portion 21 of the direct current cylinder portion 22 flows is a range converged in a substantially cylindrical shape, and the upward flow is formed in a substantially direct current shape. In the present embodiment, the small-divided cylindrical member 24 is formed of a cylindrical straight pipe made of synthetic resin such as plastic and having both ends opened. The small divided cylindrical member 24 is provided to be somewhat long in the axial direction, and has an upper end side opening as a jet port 24a and a lower end side opening as a suction port. As shown in FIG. 5, in plan view, the size of the outer contour bundle of the small divided cylindrical members 24 is slightly larger than the size of the blades of the blower fan 20. Is sent into the small divided cylindrical member 24.

  In the present embodiment, the floating body 14 is levitated up to a certain height position in the air within the regulation frame 16 by being ejected as a substantially DC upward flow. In a state in which the flow of other air is almost negligible with only the upward flow, the floating body 14 that floats in the vicinity of the aerial position stabilizes the floating state so that it stays within the range where the upward flow flows without falling sideways and falling. Retained. That is, the direct current cylinder part 22 is provided so as to eject the floating body 14 as a substantially direct current upward flow that can stop and hold the floating body 14 at a required air position in the restriction frame 16. Therefore, in this embodiment, the floating body 14 continues to be levitated at a required height in the air by causing the direct current cylindrical portion 22 to eject the direct current fast flow to form a rising flow, so that it floats softly. A unique floating motion can be realized. Further, in the vicinity of the fast flow in which the upward flow flows, a force acts to draw the floating body 14 that is separated from the range of the upward flow into the fast flow of the upward flow. In addition, the phenomenon that the floating body is held in the air in the upward flow is, for example, the balance between the wind pressure of the upward flow and the weight of the floating body, or the action that the pressure decreases at a fast flow (Bernoulli's theorem ), When the flow bends, the pressure inside the bend is low and the outside is high (streamline curvature theorem), the flow flows along the surface of the floating body (Coanda effect), etc. Presumed to occur. Although the upward flow may be ejected so as to be distributed radially, for example, the floating height of the floating body 14 is reduced and the floating time in the air is shortened as compared with the direct current upward flow. is expected.

  As shown in FIGS. 1, 4, and 6, the floating body 14 floats in the air by the upward flow from the upward flow generation device 12, and generates a visual effect due to the floating operation. In this embodiment, the floating body 14 is made of, for example, a paper or rubber balloon ball in which the same air as the atmosphere is enclosed. The floating body 14 is formed in a substantially spherical body. Since the balloon ball is lightweight as a whole, the floating body 14 can float gently and gently in the air from side to side under the influence of the upward flow F as described above. Moreover, it is easy to move under the influence of other air flows such as upward flow and air conditioning. In the present embodiment, the floating body 14 is provided with a diameter larger than the diameter of the ejection portion 21, for example. In addition, the diameter of the floating body 14 may be substantially the same as or smaller than the diameter of the ejection part 21, and it depends on the movement of the floating body and the moving speed depending on the diameter of the floating body 14, the size of the ejection part 21, and the jet power. Changes are likely to occur. The shape of the floating body 14 is not limited to a sphere, and is preferably a convex arcuate curved surface having a gentle upward surface that receives an upward flow, for example, an elliptical sphere, an egg shape, or a curve with an arbitrary curvature convex outward. The shape of a rotating body or the like may be used. For example, a light reflecting material made of, for example, a metal foil such as aluminum that reflects light is attached to the entire surface of the floating body 14 so as to reflect illumination of the lighting device 26 described later. The floating body 14 may be formed in various forms such as a pattern or a picture on the surface, a colorless or colored transparent material, a fluorescent paint applied, or the like.

  As shown in FIGS. 1, 2, and 4, the regulation frame 16 is a regulation unit that accommodates the floating body 14 and regulates the movement range thereof, and further controls the movement of the floating body 14 to the outside. The gap 28 is visible from the outside. The restriction frame 16 forms a moving space S in which the floating body 14 can freely move and restrains the floating body 14 in the moving space S. In the present embodiment, the restriction frame 16 is provided so as to form a moving space S of the floating body 14 that extends in the lateral direction from the range in which the upward flow F flows. As a result, the range in which the floating body can move is wide, and the floating body 14 can move so as to fall off the upward flow F, and a complicated movement of the floating body 14 can be expected. In the present embodiment, the upward flow generating device 12 is disposed below the left and right central positions of the restriction frame 16 in a front view, and the ejection portion 21 of the upward flow generation device 12 faces the restriction frame 16. A moving space S formed by the restriction frame 16 is provided so as to spread on both the left and right sides. The gap 28 is provided so that, for example, when viewed from the outside, the floating body 14 floating in the moving space S can visually recognize a part larger than the area hidden by the restriction frame 16. The outline and movement of the outline can be easily grasped. At the same time, the gap 28 needs to be provided in such a size that the floating body does not leave. In this embodiment, for example, the size of the gap 28 is set smaller than the diameter of the floating body 14 having a substantially spherical shape. Has been. Further, the gap 28 can allow the air flow to freely enter and exit the inside of the restriction frame 16. In the present embodiment, the communication direction of the gap is provided in a direction intersecting with the flow of the upward flow F. For example, the floating body 14 can be floated with a more interesting and unique movement by acting on a floating body in which air-conditioning equipment, wind, etc. are floating through the gap 28. The upward flow F is discharged to the outside through the gap 28 while a part of the upward flow F hits the upper side of the regulation frame 16.

  In the present embodiment, the restriction frame 16 has a plurality of ribbon-like shapes that are spaced apart from each other so as to form a gap 28 having a size that prevents the floating body 14 from escaping from the restraint of the restriction frame 16 and escaping. Band members 301 to 307 are included. As shown in FIG. 3, the restriction frame 16 includes an arch-shaped frame body 32 formed by assembling seven band members 301 to 307 curved in an arch shape. Thereby, the design nature like ribbon decoration can be used for the regulation frame 16, and the commercial value as a display apparatus can be improved. Furthermore, the restriction frame 16 can be configured with a simple structure, and the display device can be manufactured at a low cost. The band members 301 to 307 are, for example, colored transparent or colorless transparent colored with various colors in the longitudinal direction, and flexible vinyl chloride resin that can maintain the curved shape of the arch. Made of synthetic resin. The belt members may have different colors. The band members 301 to 307 are provided so as to be curved in an arch shape that extends obliquely upward or directly upward from the front side and goes to the back side so as to be formed in an arch shape in a side view, Both ends thereof are fixed to the base 18 via a pair of support pieces 34 protruding upward from the base 18. The support piece 34 is formed of a substantially L-shaped metal thin strip that is integrally fixed to the upper end of the base 18 in the front-rear direction. For example, the strip members 301 to 307 are fixed by fixing means such as bolts and nuts. The end of is fixed.

  In the present embodiment, the arch-shaped frame body 32 forms a moving space S of the floating body 14 by a space in which a space surrounded by the curved inner side of the belt members 301 to 307 curved in an arch shape is continuous left and right. . In the embodiment of FIG. 1, the arch-shaped frame body 32 is provided such that the band members 301 to 307 spread radially like a fan bone with the support piece 34 as a fulcrum in front view. That is, the arch-shaped frame body 32 is provided so that both end portions of the band members 301 to 307 converge on the support piece 34 and intermediate curved portions are separated from each other. The gap 28 formed by the separation between the band members is formed in an arch shape, and the gap width is small on the lower side of the regulation frame 16 (on the end side of the band member) and on the upper side of the regulation frame (on the band member). It is formed so as to increase gradually toward the center side). The size of the separation between the central portions of the band member that is the maximum width of the gap 28 is set smaller than the diameter of the floating body 14. Further, the length of the band member is increased from the band members 301 and 307 arranged on the lower left and right sides forming the lower side of the restriction frame 16 in accordance with the increase in the inclination angle from the horizontal direction. In addition, the length of the band member 304 oriented in the vertical direction arranged at the center of the left and right is set to be the maximum. Therefore, the moving range S is formed around the range in which the upward flow flows, the range in which the floating body 14 floats and moves is relatively wide in the vertical and horizontal directions, and the floating body 14 that is floating while receiving the upward flow is the belt member. Is relatively difficult to collide with.

  The band members 301 and 307 arranged on the left and right lower sides have a gap 28b in the gap inside the arch, and the length and the width of the gap are set so that the floating body 14 does not leave the gap 28b. Furthermore, since the band members 301 and 307 disposed on the lower left and right sides are provided obliquely so that the upward flow generating device 12 side is lowered, the floating body that has fallen on the band members 301 and 307 (FIG. 6). The upper virtual line 14f) is guided to the upflow generator 12 side so as to roll in the arrow D direction in FIG. 6 while hitting the band members 301 and 307. That is, the regulation frame 16 has a drop guide portion 36 that guides the floating body 14 that is laterally separated from the upward flow and falls to the lower side of the moving space to the vicinity of the ejection portion side of the upward flow generation device. In the embodiment, the band members 301 and 307 constituting a part of the restriction frame serve as the drop guide portion 36. Thereby, the floating body 14 that has left the side of the upward flow and has fallen to the lower side of the moving space S can be suspended again in the upward flow, and without the need for monitoring or complicated control, The display effect by movement can be maintained. Note that the restriction frame 16 may be provided so that the floating body 14 does not separate laterally from the range in which the upward flow flows, that is, so as to form a moving space S having such a size that the floating body 14 does not fall. Further, the number, length, lateral width, separation width, and the like of the band members 301 to 307 constituting the restriction frame 16 can be arbitrarily set. Moreover, it is good also as making the belt | curve member curved in the shape of an arch intersect. The restriction frame 16 is not limited to the embodiment, but includes a frame structure using thin frame members, a lattice frame structure, a mesh frame structure, a structure in which holes are formed in a box shape or a cylindrical shape, a single long band member, a wire, or the like. Any other configuration such as a structure in which the rope member is formed in a spiral shape while forming a space therein may be used. In addition, the restriction frame 16 is formed by using a pair of male and female attachment / detachment members such as hook-and-loop fasteners and buttons, for example, an engaging portion provided on the end side of the band member, and a band provided on the upflow generator side. The attachment receiving part which receives the engagement part of a member is comprised, and the part or all the belt members 301-307 which form the frame with respect to the upward flow generator 12 and the base 22 are comprised. It is good also as providing detachably. Thereby, the replacement of the floating body and the maintenance of the apparatus can be easily performed. Furthermore, if a plurality of types of restriction frames or belt members having different sizes, shapes, designs, etc. are prepared, they can be freely exchanged as necessary. Note that the attachment / detachment mechanism has, for example, a configuration in which the end portion of the band member itself is an engaging portion, and a receiving hole through which the band member can be freely inserted and removed is an engaging receiving portion, or a notch is formed in the end portion of the band member. The engaging member may be formed as an engaging portion, and a protruding member protruding in a hook shape on the upward flow generating device side may be used. Moreover, the structure using other connection members, such as a volt | bolt and a nut, and other arbitrary attachment / detachment structures may be sufficient. Further, the restriction frame 16 may be configured such that the separation width between the band members 301 to 307 can be freely changed so that the size of the gap 28 or the size of the moving space S can be freely changed. At this time, for example, the band members 301 to 307 are configured to rotate around the connecting portion with the support piece 34 with the end portions assembled, and the band members 301 to 307 are freely fan-shaped. It is good also as a structure which can be converged and developed. Thereby, when carrying or storing, the entire apparatus can be made compact, and the floating body regulating means can be easily formed at the installation location. In addition, a plurality of holes spaced apart from each other along the longitudinal direction or long holes formed along the longitudinal direction are previously drilled on one end or both end sides of the band members 301 to 307, and these holes are formed as arbitrary holes. It may be configured such that it can be connected to the support piece 34 at a position so that the arc length of the arch can be changed. The restriction frame 16 is, for example, a material that can be deformed so as to be bent, bent, stretched and can hold its shape, such as a band member made of soft metal such as thin aluminum, cloth, thin synthetic resin, etc. The belt member may be composed of a wire or the like as a core material, or a wire such as a molding obtained by combining colored yarn, vinyl, or the like. As a result, the restriction frame can be freely deformed into a desired shape by a simple operation by simply applying force to the band member or the like, and the decoration can be changed. Moreover, the belt members 301 to 307 may be provided so as to vibrate under the influence of wind such as upward flow or air conditioning. Moreover, you may comprise the control frame 16 so that it can rotate to a raise vertical axis | shaft or horizontal axis periphery, for example. At this time, as the rotational drive of the regulation frame 16, for example, a motor drive may be used, and a configuration such as a configuration that rotates in response to a wind flow such as an upward flow may be provided arbitrarily. By giving an action to the regulation frame, a more interesting display effect can be expected.

  Further, in the present embodiment, as shown in FIGS. 1, 2, and 3, the display device 10 is provided with an illumination device 26 that irradiates light to the floating body 14 and the regulation frame 16. The lighting device 26 can be expected to have a more interesting display effect in combination with the visual effect given by the unique movement of the floating body 14 as well as the effect of illumination. In this embodiment, the illuminating device 26 is composed of white light bulbs fixed to the left and right of the base 18 in FIG. 1, and the light irradiation direction is set upward, and irradiates light in a divergent shape. The light emitted from the illuminating device 26 is reflected on the surface of the floating body 14, and at the same time, passes through the colored transparent (or colorless and transparent) belt members 301 to 307, or passes through the gap 28 of the restriction frame 16, It will be visually observed, and a unique lighting effect with a sense of design can be expressed. The illumination device 26 may be attached so that only the floating body 14 or only the restriction frame 16 is illuminated. Moreover, the attachment position of the illuminating device 26 is not limited to the said position, For example, it is good also as attaching to the arbitrary places of the base 18 or the control frame itself. The number of light bulbs may be one or more than two.

  When using the display apparatus 10, it arrange | positions, for example on the floor surface of a room | chamber interior. An upflow is generated by operating the blower fan of the upflow generator 12. At the same time, the lighting device 26 is turned on to illuminate the floating body 14 and the regulation frame 16. The floating body 14 is levitated in the air up to a height position in the regulation frame 16 by the substantially DC upward flow F from the upward flow generator 12. The floating body 14 floats in the air by the upward flow F so as to float in all directions in the left, right, front, rear, top and bottom directions so as to stay within the range of the upward flow. At this time, for example, due to the influence of wind from the air conditioner that enters the restriction frame 16 through the gap 28 of the restriction frame 16 or from the outside, the turbulent flow or vortex generated when the upward flow F hits the restriction frame 16, It is considered that a complicated air flow other than the upward flow F acts on the floating body. And it is thought that the force which can move to the direction (X1) which goes to the central axis of the upward flow F and the force which moves to the direction (X2) which goes outside from the central axis of the upward flow F act on the floating body 14 The body 14 floats with a unique and interesting movement. Even when the floating body 14 floats to the left and right, the floating body is restricted from moving by the restriction frame 16 and floats in the movement space even if the floating body 14 is separated beyond the range in which the upward flow F flows. In addition, the floating body 14 separated beyond the range in which the upward flow F flows gently falls in the moving space and falls on the band members 301 and 307 below the restriction frame 16. At this time, the band members 301 and 307 guide the floating body to the ejection portion of the upward flow generation device 12 as the drop guide portion 36. Then, the floating body 14 is again drawn into the range of the upward flow and floated to the air position, and floats in the air. As described above, even if special wind control and monitoring are not required, the floating body can be floated substantially continuously or intermittently in the regulation frame 16 and the movement can be enjoyed.

  In addition, it is good also as a structure which can move not only the aspect which arrange | positions the display apparatus 10 itself in the state which does not move on the floor etc. like the said embodiment, but the display apparatus 10 whole. For example, a configuration in which driving wheels are provided below the base 18 so that the display device itself can run, or a configuration in which the display device is operated by a rail or the like may be used. Alternatively, any other configuration such as a configuration in which the entire display device rotates around the vertical axis, a configuration in which the display device swings back and forth or right and left may be employed. If the display device itself is also moved, a more unique display effect can be expected.

  The display device of the present invention described above is not limited to the configuration of the above-described embodiment alone, and may be arbitrarily modified without departing from the essence of the present invention described in the claims. .

  The display device of the present invention includes, for example, department stores, supermarkets, retail stores, restaurants, pachinko stores, game playgrounds, amusement parks, other stores and playgrounds, parties and events, exhibition halls, exhibition halls, etc. It is applied in various places such as decoration, atmosphere creation, sales promotion, etc. in various places.
