Mode for Carrying Out the Invention

[0015] Hereinafter, an embodiment for implementing the present disclosure will be described with reference to the drawings and the like.

[0016] (Embodiment) FIG. 1 is a perspective view showing an embodiment of the game device 1 according to the present disclosure. FIG. 2 is a front view showing an embodiment of the game device 1. FIG. 3 is a side view showing an embodiment of the game device 1. FIG. 4 is a cross-sectional view of the game device 1 cut at the position of arrow A - A in FIG. 3. FIG. 5 is an enlarged cross-sectional view showing the vicinity of the tension adjusting part 80 in FIG. 4. In the following description, specific numerical values, shapes, materials, etc. are shown for the description, but these can be changed as appropriate. Also, in the figure, orthogonal coordinates of X, Y, and Z are provided for convenience of explanation, and in the following description, the orientation of each part and the like will be described using these coordinates. When the game device 1 of the embodiment is placed on a horizontal plane, the X-axis and the Y-axis are parallel to the horizontal plane, and the Z-axis is parallel to the vertical direction. Also, in the specification, words indicating directions such as "upper side" and "lower side" indicate the orientation when the game device 1 is placed on a horizontal plane.

[0017] The game device 1 of this embodiment includes a base portion 10, a movable portion 20, a first arm portion 30, a second arm portion 40, a first opposing portion 50, a second opposing portion 60, a connecting portion 70, a tension adjusting portion 80, and a protection portion 90.

[0018] (Basic Configuration of Game Device 1) The base portion 10 is a member disposed on the lowermost side (-Z side) in the usage state of the game device 1. In the usage state of the game device 1 of this embodiment, that is, during the game, the base portion 10 is placed on a substantially horizontal surface such as a table for use. Note that the content of the game will be described later. The base portion 10 of this embodiment is configured by fixing a first base member 11 and a second base member 12 with a screw 13. Note that the fixing of the first base member 11 and the second base member 12 may be performed by adhesion or welding, etc., and in this case, the screw 13 may be omitted. The first base member 11 and the second base member 12 are each configured by pressing a metal plate. Further, a fixing plate 14 is attached to the inner surface of the first base member 11. The lower end portion of the ball chain of the connecting portion 70 described later is hooked on the fixing plate 14, and by fixing the fixing plate 14 to the base portion 10, the lower end portion of the connecting portion 70 is fixed to the base portion 10. The fixing plate 14 can be attached to the inner surface of the first base member 11 by, for example, welding or adhesion. The base portion 10 of this embodiment is configured to have an overall shape of a substantially rectangular parallelepiped shape.

[0019] The movable part 20 is positioned above the base part 10 (+Z side) and has a mounting part 20a on its upper surface on which an item is placed. The movable part 20 has the same configuration as the base part 10, except for its position and orientation. That is, the movable part 20 of this embodiment is constructed by fixing a first movable member 21 and a second movable member 22 with screws 23. Note that the fixing of the first movable member 21 and the second movable member 22 may be done by adhesive or welding, in which case the screws 23 may be omitted. The first movable member 21 and the second movable member 22 are each constructed by press-forming metal plates. A fixing plate 24 is attached to the inner surface of the second movable member 22. The upper end of the ball chain of the connecting part 70, which will be described later, is hooked onto the fixing plate 24, and the fixing plate 24 is fixed to the movable part 20, thereby fixing the upper end of the connecting part 70 to the movable part 20. The fixing plate 24 can be attached to the inner surface of the second movable member 22, for example, by welding or adhesive. The movable part 20 in this embodiment is configured to have a substantially rectangular parallelepiped shape overall. Therefore, the mounting part 20a is a flat surface, making it easy to place an item on it. Note that the mounting part 20a is not limited to a flat surface, but may also have a curved surface or various uneven shapes.

[0020] The first arm portion 30 is provided projecting from the base portion 10 toward the movable portion 20, i.e., toward the upper side (+Z side). The first arm portion 30 in this embodiment has a first arm body 31 and a first arm fastener 32. Both the first arm body 31 and the first arm fastener 32 are made of metal plates. One end of the first arm body 31, the root side, is fixed to the base portion 10, and the other end, the tip side, is fixed to the first arm fastener 32. The first arm body 31 and the base portion 10, and the first arm body 31 and the first arm fastener 32 can be fixed by adhesive or welding.

[0021] The second arm portion 40 is provided projecting from the movable portion 20 toward the base portion 10, i.e., toward the downward (-Z) side. The second arm portion 40 has the same configuration as the first arm portion 30, except for its position and orientation. That is, the second arm portion 40 of this embodiment has a second arm body 41 and a second arm fastener 42. Both the second arm body 41 and the second arm fastener 42 are made of metal plates. One end of the second arm body 41, the root side, is fixed to the movable portion 20, and the other end, the tip side, is fixed to the second arm fastener 42. The second arm body 41 and the movable portion 20, and the second arm body 41 and the second arm fastener 42 can be fixed by adhesive or welding.

[0022] In this embodiment, the base portion 10, the movable portion 20, the first arm portion 30, and the second arm portion 40 are all made of aluminum alloy, but other metal materials may be used, or materials other than metal, such as resin or wood, may be used. Furthermore, these parts may be configured as a single component, or they may be composed of more components than in this embodiment. For example, the base portion 10 and the first arm portion 30 may be made as a single component, or the movable portion 20 and the second arm portion 40 may be made as a single component.

[0023] The first opposing portion 50 is a permanent magnet positioned on the tip side (upper side, +Z side) of the first arm portion 30, facing toward the base portion 10. A neodymium magnet can be suitably used as the magnet for the first opposing portion 50. A fixing hole 50a is provided in the first opposing portion 50. The first opposing portion 50 is fixed to the first arm fastener 32 by screwing a screw 51 that passes through the fixing hole 50a into a nut 52. In this embodiment, the nut 52 is a press-fit nut (self-clinching fastener) that is fixed by press-fitting it into a pilot hole provided in the first arm fastener 32. Note that the nut 52 is not limited to a press-fit nut; for example, the nut may be provided on the first arm fastener 32 by welding or crimping, or an internal thread may be directly formed on the first arm fastener 32.

[0024] The second opposing part 60 is positioned opposite the first opposing part 50 on the tip side (lower side, -Z side) of the second arm part 40, facing the movable part 20, and is a permanent magnet that attracts the first opposing part 50. A neodymium magnet can be suitably used as the magnet for the second opposing part 60. The second opposing part 60 has a screw hole 60a, and is attached to the second arm fastener 42 via a tension adjustment part 80, which will be described later, using this screw hole 60a.

[0025] The connecting portion 70 is spanned between the base portion 10 and the movable portion 20 and is configured to be deformable. The connecting portion 70 functions as a tension member connecting the rigid bodies (base portion 10, movable portion 20, first arm portion 30, second arm portion 40) in the tensegrity structure described later. In this embodiment, the connecting portion 70 is made of a ball chain. The connecting portion 70 can preferably be made of a material that does not stretch when tension is applied, or stretches only slightly, and can deform and bend when the tension is released, such as a rope, string, or cord. Therefore, the connecting portion 70 is not limited to a ball chain; it may be a regular chain made of connected ring-shaped members, or a wire, and is not limited to metal; it may be a rope or string made of resin, fiber, etc.

[0026] In this embodiment, the connecting parts 70 are connected to the respective corners (four corners) of the base part 10 and the movable part 20, and are provided in four locations (four pieces). The first opposing part 50 and the second opposing part 60 are positioned within the area enclosed by the four connecting parts when viewed from above. Note that the number of connecting parts is not limited to four; it may be three or five or more.

[0027] With the configuration described above, the game device 1 of this embodiment constitutes a so-called tensegrity structure. In the game device 1 of this embodiment, the tension caused by the attraction between the first opposing part 50 and the second opposing part 60 exerts a force that pushes the base part 10 downward (-Z side) and a force that pushes the movable part 20 upward (+Z side). These forces apply tension to each of the four connecting parts 70. As a result, the positional relationship between the base part 10 and the movable part 20 can be maintained at the positions shown in Figures 1 to 4, making it appear as if the movable part 20 is floating in mid-air.

[0028] Here, the movable part 20 can be maintained in the position shown in Figures 1 to 4, where tension is applied to each of the four connecting parts 70, making it appear as if the movable part 20 is floating in mid-air (the position shown in Figures 1 to 4; hereinafter also referred to as the "standard position"), when the total weight of the components integrated with the movable part 20 (the gravitational force acting on them) (hereinafter also referred to as the total weight of the movable part 20, etc.) is less than the force of attraction between the first opposing part 50 and the second opposing part 60. Here, the total weight of the components integrated with the movable part 20 is the sum of the weight of the movable part 20, the weight of the second arm part 40, the weight of the second opposing part 60, the weight of the four connecting parts 70, the weight of the tension adjustment part 80, and the weight of an unshown item placed on the mounting part 20a of the movable part 20 (if an item is placed). Therefore, when the total weight of the movable part 20 etc. becomes greater than the tensile force between the first opposing part 50 and the second opposing part 60, the movable part 20 will fall downward (towards the -Z side). Thus, when the movable part 20 is in its standard position and more items are placed on the mounting part 20a of the movable part 20, the movable part 20 will fall downward (towards the -Z side) when the total weight of the movable part 20 etc. becomes greater than the tensile force between the first opposing part 50 and the second opposing part 60.

[0029] (Game Overview) In the game device 1 of this embodiment, the action taken by game participants during the game is to place items on the placement area 20a of the movable part 20 until the movable part 20 falls downward (towards the -Z side). The specific method for determining the winner and the detailed rules for placing items can be set as appropriate. For example, game participants could take turns placing predetermined items, such as blocks prepared for the game, on the placement area 20a, and the game participant who causes the movable part 20 to fall could be declared the loser. Alternatively, multiple types of blocks with different weights and sizes could be prepared, and the ranking could be determined by the weight of the blocks that could be placed before the movable part 20 fell. Furthermore, the items placed on the placement area 20a of the movable part 20 are not limited to blocks; they could also be in the form of dolls or other objects. In any case, the game device 1 of this embodiment uses the change in state between the movable part 20 being in its standard position and being in a fallen position as an important action (event) in the game. Therefore, in the game device 1 of this embodiment, the relationship between the total weight of the movable parts 20 and the magnitude of the attractive force between the first opposing part 50 and the second opposing part 60 is an important factor in determining the winner. Note that the above game content is an example and can be changed as appropriate.

[0030] However, as the game is played repeatedly, players may learn through experience how much (number or weight) of items can be placed on the mounting section 20a before the movable section 20 falls. This could reduce the enjoyment of the game and lead to boredom. Therefore, the game device 1 of this embodiment is provided with a tension adjustment section 80.

[0031] (Tension adjustment part) The tension adjustment unit 80 adjusts the tension acting on the connecting portion 70 as the first opposing portion 50 and the second opposing portion 60 pull against each other. In this embodiment, the tension adjustment unit 80 adjusts the tension by changing the relative positions of the first opposing portion 50 and the second opposing portion 60. More specifically, the tension adjustment unit 80 adjusts the tension by changing the vertical distance (Z-axis direction) between the first opposing portion 50 and the second opposing portion 60.

[0032] The tension adjustment section 80 of this embodiment includes an adjustment knob 81 and a nut 82.

[0033] The adjustment knob 81 has a knob portion 81a and a male threaded portion 81b. The knob portion 81a is the part that game participants can touch with their hands to rotate the adjustment knob 81. The male threaded portion 81b is a male threaded portion provided integrally with the knob portion 81a, and the side closer to the knob portion 81a (the lower side, the -Z side) is screwed into the nut 82. The tip side of the male threaded portion 81b, which is closer to the first opposing portion 50 (the upper side, the +Z side), is screwed into the threaded hole 60a provided in the second opposing portion 60. It is desirable that the tip of the male threaded portion 81b and the threaded hole 60a of the second opposing portion 60 be fixed together by adhesive or the like.

[0034] In this embodiment, the nut 82 is a press-fit nut (self-clinching fastener) that is fixed by press-fitting it into a pilot hole provided in the second arm fastener 42. Note that the nut 82 is not limited to a press-fit nut; for example, the nut may be attached to the second arm fastener 42 by welding or crimping, or an internal thread may be formed directly on the second arm fastener 42.

[0035] As described above, the second opposing part 60 is attached to the second arm part 40 via the threaded portion (male threaded portion 81b and nut 82) of the tension adjustment part 80. The vertical position (Z direction) of the second opposing part 60 can be adjusted by rotating the adjustment knob 81 to change the screwing position of the threaded portion (male threaded portion 81b and nut 82). As the vertical position (Z direction) of the second opposing part 60 changes, the attractive force (the force of mutual attraction due to magnetic force) between the first opposing part 50 and the second opposing part 60 changes. In other words, the tension can be easily adjusted by turning the knob 81a of the tension adjustment part 80.

[0036] Figure 5 illustrates an example where a gap exists between the first opposing part 50 and the second opposing part 60 at the uppermost position of the adjustment knob 81. However, the range in which the second opposing part 60 can be moved by adjustment can be changed as appropriate. For example, the second opposing part 60 may be moved by adjustment to a position where it comes into contact with the first opposing part 50.

[0037] By adjusting the tension using the tension adjustment unit 80, the upper limit of the weight of an item that can be placed on the mounting unit 20a while the movable unit 20 is in its standard position can be changed. When the distance between the first opposing unit 50 and the second opposing unit 60 is reduced, the tension acting on the connecting unit 70 increases, so the weight of an item that can be placed on the mounting unit 20a while maintaining the movable unit 20 in its standard position increases. On the other hand, when the distance between the first opposing unit 50 and the second opposing unit 60 is increased, the tension acting on the connecting unit 70 decreases, so the weight of an item that can be placed on the mounting unit 20a while maintaining the movable unit 20 in its standard position decreases.

[0038] In other words, by adjusting the tension using the tension adjustment unit 80, it is possible to change the weight of an item that can be placed on the mounting unit 20a while maintaining the movable unit 20 in the standard position. If the tension acting on the connecting unit 70 is constant, there is a risk that if the game using the game device 1 of this embodiment is played repeatedly, the game participants will learn the upper limit of the weight of an item that can be placed on the mounting unit 20a when the movable unit 20 is in the standard position. In that case, the element of surprise and randomness will be lost, and it is conceivable that players will get bored with the game. In the game device 1 of this embodiment, by adjusting the tension using the tension adjustment unit 80, the upper limit of the weight of an item that can be placed on the mounting unit 20a when the movable unit 20 is in the standard position can be changed. Therefore, by adjusting the tension using the tension adjustment unit 80, each game will have an element of surprise and randomness, making it less likely to get boring and allowing players to enjoy the game repeatedly. In addition, since the tension adjustment unit 80 adjusts the position of the second opposing unit 60 by changing the screwing position of the screw part, slight position changes (adjustments) can be made easily and freely.

[0039] (Other additional configurations) The protective part 90 is provided on the surface of the base part 10 facing the movable part 20. More specifically, the protective part 90 is provided at the position where the second arm part 40 would collide with the base part 10 if the movable part 20 were to fall from its standard position. The protective part 90 protects the position where the second arm part 40 would collide with the base part 10 if the movable part 20 were to fall from its standard position. For example, a rubber sheet, a resin sheet, etc., can be suitably used as the protective part 90. In this embodiment, a 1.5 mm thick sponge was fixed onto the base part 10 with adhesive tape (double-sided tape). Note that the protective part 90 may be omitted. Also, a protective part similar to the protective part 90 may be provided on the surface of the movable part 20 facing the base part 10.

[0040] The tension adjustment unit 80 in this embodiment is visible, and the distance between the first opposing unit 50 and the second opposing unit 60 is also visible. Therefore, game participants can visually confirm how the tension has been adjusted by the tension adjustment unit 80. As a result, there is a risk that game participants may learn information such as whether the tension has been adjusted to increase or decrease compared to the previous game. Therefore, the game device 1 in this embodiment is further provided with a concealing member 100.

[0041] Figure 6 is a perspective view showing the concealing member 100 by itself. Figure 7 is a diagram showing the concealing member 100 in a state where it is attached to cover the first opposing part 50, the second opposing part 60, and the tension adjustment part 80 (hereinafter also referred to as the "attached state"). The concealing member 100 in this embodiment is configured in a substantially rectangular parallelepiped shape, with one face of the rectangular parallelepiped being open (open). In this embodiment, the concealing member 100 is constructed by press-forming a metal plate. In this embodiment, the concealing member 100 is made of an aluminum alloy, but other metal materials may be used, or materials other than metal, such as resin or wood, may be used.

[0042] The concealing member 100 has a top surface 101, an opening 102, side surfaces 103, 104, 105, and 106, a first slit 107, and a second slit 108. The top surface 101 is the surface positioned above the first opposing portion 50, the second opposing portion 60, and the tension adjustment portion 80 when installed. The opening 102 is positioned opposite the top surface 101 and opens downwards (towards the -Z side) when installed. The side surfaces 103, 104, 105, and 106 surround the first opposing portion 50, the second opposing portion 60, and the tension adjustment portion 80 when installed. The first slit 107 is located on side surface 106. When installed, the first arm portion 30 passes through the first slit 107. The second slit 108 is located on side surface 105. When worn, the second arm portion 40 passes through the second slit 108.

[0043] When attaching the concealing member 100, it can be easily attached to the game device 1 by placing it over the first opposing part 50 and the second opposing part 60 with the opening 102 facing downwards. Furthermore, since the concealing member 100 has an opening 102, the tension can be adjusted by the tension adjustment part 80 even when it is attached. Moreover, the concealing member 100 of this embodiment is detachably attached in a position that covers the first opposing part 50, the second opposing part 60, and the tension adjustment part 80. Therefore, the game can be played by selecting either a state in which the first opposing part 50, the second opposing part 60, and the tension adjustment part 80 are concealed or a state in which they are not concealed. Note that the concealing member 100 is not an essential component, and the game device may be made without the concealing member 100.

[0044] As explained above, the game device 1 of this embodiment is equipped with a tension adjustment unit 80, so the conditions under which a state change (event) occurs between the movable part 20 being in the standard position and being in the downward position can be freely changed for each game. Therefore, the game device 1 of this embodiment has an element of surprise and randomness in each game, making it less likely to become boring and allowing players to enjoy the game repeatedly. In addition, since the game device 1 of this embodiment has a tensegrity structure, the movable part 20 appears to be floating in mid-air, allowing players to enjoy the game while experiencing a sense of wonder and fun.

[0045] (Transformed form) The embodiments described above are not limited to those described above, and various modifications and changes are possible, which are also within the scope of this disclosure.

[0046] (Modified form-1) In this embodiment, an example was given in which the first opposing part 50 is immovable and the second opposing part 60 is movable. However, the invention is not limited to this, and for example, the first opposing part 50 may be made movable and the second opposing part 60 may be fixed, or both the first opposing part 50 and the second opposing part 60 may be made movable.

[0047] (Modified form-2) In the embodiment described, the tension adjustment unit 80 was described as changing the distance between the first opposing part 50 and the second opposing part 60 in the direction in which the first opposing part 50 and the second opposing part 60 face each other, i.e., in the vertical direction (Z direction). However, the tension adjustment unit may be configured to adjust the tension by moving at least one of the first opposing part 50 and the second opposing part 60 in a direction intersecting the direction in which the first opposing part 50 and the second opposing part 60 face each other.

[0048] Figure 8 illustrates one example of a configuration in which at least one of the first opposing part 50 and the second opposing part 60 is moved in a direction intersecting the direction in which the first opposing part 50 and the second opposing part 60 face each other. In the example shown in Figure 8, the first opposing part 50 and the second opposing part 60, which face each other in the Z direction, are each made capable of moving in a straight line in the X direction. In the example in Figure 8, the first opposing part 50 and the second opposing part 60 are shown as being capable of moving in the X direction, but they may also be made capable of moving in the Y direction. Furthermore, only one of the first opposing part 50 or the second opposing part 60 may be moved.

[0049] Figure 9 illustrates another example of a configuration in which at least one of the first opposing part 50 and the second opposing part 60 is moved in a direction intersecting the direction in which the first opposing part 50 and the second opposing part 60 face each other. In the example shown in Figure 9, a configuration is illustrated in which the first opposing part 50 and the second opposing part 60, which face each other in the Z direction, are each capable of rotation (rotation in the XZ plane). In the example in Figure 9, the first opposing part 50 and the second opposing part 60 are shown as being capable of rotation (rotation in the XZ plane) around the Y axis, but the first opposing part 50 and the second opposing part 60 may also be capable of rotation around the X axis or the Z axis. Furthermore, only one of the first opposing part 50 or the second opposing part 60 may be moved.

[0050] (Modified form-3) In this embodiment, the tension adjustment unit 80 was described as adjusting the tension by providing a second opposing part 60 movably to the second arm fastener 42 of the second arm 40. However, the specific mechanism for adjusting the tension is not limited to this and can be changed as appropriate. For example, the first arm 30 or the second arm 40 may be configured to move linearly or rotate relative to the base 10 or the movable part 20. Alternatively, for example, the first arm fastener 32 or the second arm fastener 42 may be configured to move linearly or rotate relative to the first arm body 31 or the second arm body 41.

[0051] (Modified form-4) In this embodiment, a form in which the concealing member 100 is detachable is illustrated. However, it is not limited to this, and for example, the concealing member may be fixed. Figure 10 shows a concealing member 100B fixed to the second arm 40. As shown in Figure 10, the concealing member 100B may be fixed to the second arm 40. Also, although Figure 10 illustrates an example in which the knob 81a is exposed, a concealing member may be provided to conceal the knob 81a as well.

[0052] (Modified form-5) In this embodiment, both the first opposing part 50 and the second opposing part 60 are permanent magnets, and the tension adjustment unit 80 adjusts the tension by changing the distance between the first opposing part 50 and the second opposing part 60. However, the invention is not limited to this, and for example, at least one of the first opposing part and the second opposing part may be an electromagnet. In this case, the tension adjustment unit can adjust the tension by changing the value of the current flowing through the electromagnet.

[0053] (Modified form-5) In this embodiment, an example was given in which both the first opposing part 50 and the second opposing part 60 are permanent magnets. However, the invention is not limited to this, and for example, one part may be a magnet (permanent magnet or electromagnet), and the other part may be made of a ferromagnetic material that is attracted by the magnetic force of the magnet. Examples of ferromagnetic materials include iron, nickel, cobalt, and alloys thereof.

[0054] While each embodiment and its variations can be used in combination as appropriate, a detailed explanation is omitted. Furthermore, this disclosure is not limited to the embodiments described above. [Explanation of Symbols]
