The present invention relates to a playing device which comprises a beam arranged such that its longitudinal direction is directed laterally, and which is configured such that a player plays by walking or running on the outer circumferential surface of the beam along the longitudinal direction.
As a playing device, conventionally, the playing device disclosed in Japanese Unexamined Patent Application Publication No. 10-314336 is known, for example. This playing device includes: a beam which is arranged such that its longitudinal direction is directed laterally and which is configured such that a player can move on the outer circumferential surface thereof under a standing state along the longitudinal direction; and a first support member and a second support member which are arranged at a distance in the longitudinal direction of the beam, and which support both end portions of the beam, respectively.
The beam is formed to have a rectangular cross-sectional shape and to be curved along its longitudinal direction. Further, the beam and each support member are adapted to be detachably assembled by the engagement relationship between an engagement portion formed at either end portion in the longitudinal direction of the beam and an engagement groove formed on each support member. The convex portion of the beam curved in an arc shape is directed upwardly, downwardly, to the right side or to the left side.
In this playing device, the player such as a child can play by, for example, walking or running on the outer circumferential surface of the beam along the longitudinal direction while keeping his/her balance. The convex portion of the beam curved in arc shape is directed upwardly, downwardly, to the right side or to the left side, thereby, the player's moving routes in this playing device can be more diversified than that in a playing device having a straight beam. Therefore, the player can play more happily.

However, even in the conventional playing device configured as described above, there are problems that the play in the playing device is apt to be monotonous and to make the player bored, and that it is difficult to interest children.
The present invention has been achieved in view of the above-described circumstances, and an object thereof is to provide a playing device in which the player can perform more diversified plays, and also which can interest children.
To achieve the above-described object, the present invention relates to a playing device, comprising:
a beam which is arranged such that its longitudinal direction is directed laterally and which is configured such that a player can move on the outer circumferential surface thereof under a standing state along the longitudinal direction; and
a first and a second support means or mechanisms which are arranged at a distance in the longitudinal direction of the beam and which support the both end portions of the beam respectively, the first and second support means or mechanisms for supporting the beam such that one or both end portions of the beam can be displaced freely in the direction intersecting the longitudinal direction.
According to this playing device, like a balance beam, the player such as a child can play by, for example, walking or running on the outer circumferential surface of the beam along the longitudinal direction while keeping his/her balance. The beam is supported by each support means or mechanism such that the one or both end portions thereof can be displaced freely in the direction intersecting the longitudinal direction (for example, the lateral direction, the up-and-down direction, the oblique direction, the rotational direction about the axis, or the pivoting direction about a pivot center axis parallel to the longitudinal direction etc.). Therefore, the player can move on the beam while the beam appropriately moves depending on the player's state of balance or the player's standing position.
Thus, according to the playing device of the present invention, the beam is configured to move. Therefore, compared with the above-described conventional playing device where the beam is fixed, it is possible to increase the difficulty in moving from one end side of the beam to the other end side, to make the player play more happily, to develop the player's sense of balance to a high level, not to make the player bored by preventing the play in the playing device from being monotonous, and to interest children.
The playing device may be configured to further comprise a drive means or mechanism for displacing one or both end portions of the beam in the intersecting direction by driving the beam. The player has to move on the beam while keeping his/her balance, while the beam is driven by the drive means or mechanism and the one or both end portions thereof are displaced. Therefore, when configured in this way, it is possible to increase the difficulty in moving from one end side of the beam to the other end side, to make the player play more happily, to develop the player's sense of balance to a high level, not to make the player bored by preventing the play in the playing device from being monotonous, and to interest children. Further, it is also possible to interest children around the playing device, who see the motion (displacement) of the beam by the drive means or mechanism, in playing with this playing device.
Further, at least one of the first support means or mechanism and the second support means or mechanism may be configured with: a first pivot member to which the end portion of the beam is connected; and a support member by which the first pivot member is supported pivotably about a first pivot center axis parallel to the longitudinal direction of the beam. In this case, when the first pivot member pivots about the first pivot center axis, one or both end portions of the beam are displaced in the direction intersecting the longitudinal direction of the beam. Therefore, the beam swings from side to side when the player cannot balance well in moving. Thus, also when configured in this way, a similar effect to the above can be obtained.
In this case, the playing device may further comprise a pivot means or mechanism for pivoting the first pivot member about the first pivot center axis. Thus, also when the first pivot member is pivoted about the first pivot center axis by the pivot means or mechanism, a similar effect to the above can be obtained.
Further, each support means or mechanism may further comprise a second pivot member to which the end portion of the beam is connected, and the first pivot member of each support means or mechanism may be configured to support the second pivot member such that the second pivot member is pivotable about a second pivot center axis parallel to the first pivot center axis. In this way, the combined motion of the pivoting of the first pivot member by the pivot means or mechanism and the pivoting of the second pivot member depending on the player's state of balance can make it more difficult for the player to move on the beam.
Additionally, the first pivot member and the second pivot member of each support means or mechanism may be configured such that the end portion of the beam is supported rotatabley about its axis. In this way, the beam rotates when the player cannot balance well. Therefore, the rotation of the beam itself can be added to the pivoting motion of the first pivot member or the pivoting motions of the first pivot member and the second pivot member, thereby being able to make it more difficult for the player to move on the beam.
In this case, the playing device may further comprise a rotation drive means or mechanism for rotating the beam about the axis thereof. Thus, also when the beam is rotated about the axis thereof by the rotation drive means or mechanism, a similar effect to the above can be obtained.
Each support means or mechanism may be configured with: a pivot member by which the end portion of the beam is supported pivotably about a first pivot center axis parallel to the longitudinal direction of the beam; and a support member by which the pivot member is supported pivotably about a second pivot center axis parallel to the first pivot center axis. And the playing device may further comprise a pivot means or mechanism for pivoting the pivot member about the second pivot center axis. Also when configured in this way, similarly to the above, the compound motion of the pivoting of the pivot member by the pivoting means or mechanism and the pivoting of the beam depending on the player's state of balance can make it more difficult for the player to move on the beam.
As described above, according to the playing device of the present invention, the playing device is configured such that the beam moves depending on the player's state of balance or the player's standing position, and such that the beam is moved by appropriate means or mechanism. Therefore, compared with the above-described conventional playing device where the beam is fixed, it is possible to increase the difficulty in moving from one end side of the beam to the other end side, to make the player play more happily, to develop the player's sense of balance to a high level, not to make the player bored by preventing the play in the playing device from being monotonous, and to interest children.

As shown in
The beam 11 is configured by a tube-shaped member having a circular cross-sectional shape, and is configured such that a player Y such as a child can move on the outer circumferential surface thereof under a standing state along the longitudinal direction (axial direction).
The first support mechanism 20 comprises: a support member 21 fixedly arranged on the upper surface of the first mount 12; the first pivot member 22 supported pivotably about a first pivot center axis parallel to the longitudinal direction of the beam 11 by the support member 21; and a second pivot member 23 which is supported pivotably about a second pivot center axis parallel to the first pivot center axis by the pivot member 22, and to which the one end of the beam 11 is connected.
The first pivot member 22 includes: a flat plate portion 22a which is formed in a flat plate and an elongate shape, and which is disposed with its longitudinal direction along the up-and-down direction; a first support shaft 22b which is projected from the lower portion of the flat plate portion 22a, and which is arranged co-axially with the first pivot center axis; and a second support shaft 22c which is projected from the upper portion of the flat plate portion 22a, and which is arranged co-axially with the second pivot center axis. The first support shaft 22b is supported rotatably by the support member 21. The first support shaft 22b is provided on the surface of the flat plate portion 22a on the side opposite to the second support mechanism 25 side, and the second support shaft 22c is provided on the surface of the flat plate portion 22a on the second support mechanism 25 side.
The second pivot member 23 includes: an engagement portion 23a which rotatably engages with the second support shaft 22c of the first pivot member 22; and a holding portion 23b which is formed below the engagement portion 23a, and which holds the one end of the beam 11 via an elastic body (not shown) such as rubber.
The second support mechanism 25 comprises: a support member 26 fixedly arranged on the upper surface of the second mount 13; a first pivot member 27 supported pivotably about a first pivot center axis parallel to the longitudinal direction of the beam 11 by the support member 26; and a second pivot member 28 which is supported pivotably about a second pivot center axis parallel to the first pivot center axis by the first pivot member 27, and to which the other end of the beam 11 is connected.
The first pivot member 27 includes: a flat plate portion 27a which is formed in a flat plate and an elongate shape, and which is disposed with its longitudinal direction along the up-and-down direction; a first support shaft 27b which is projected from the lower portion of the flat plate portion 27a, and which is arranged co-axially with the first pivot center axis; and a second support shaft 27c which is projected from the upper portion of the flat plate portion 27a, and which is disposed co-axially with the second pivot center axis. The first support shaft 27b is supported rotatably by the support member 26. The first support shaft 27b is provided on the surface of the flat plate portion 27a on the side opposite to the first support mechanism 20 side, and the second support shaft 27c is provided on the surface of the flat plate portion 27a on the first support mechanism 20 side.
The second pivot member 28 includes: an engagement portion 28a which rotatably engages with the second support shaft 27c of the first pivot member 27; and a holding portion 28b which is formed below the engagement portion 28a and which holds the other end of the beam 11 via an elastic body (not shown) such as rubber.
The first pivot mechanism 30 includes: a drive motor 31; a support member 32 which is fixedly arranged on the upper surface of the first mount 12 for supporting the drive motor 31; a rotating body 33 fixedly arranged on an output shaft of the drive motor 31; and a connecting member 34 for connecting the outer circumferential side of the rotating body 33 to between the upper end and the lower end of the first pivot member 22.
The second pivot mechanism 35 includes: a drive motor 36; a support member 37 which is fixedly arranged on the upper surface of the second mount 13 for supporting the drive motor 36; a rotating body 38 fixedly arranged on an output shaft of the drive motor 36; and a connecting member 39 for connecting the outer circumferential side of the rotating body 38 to between the upper end and the lower end of the first pivot member 27
According to the first support mechanism 20 and the first support mechanism 30, when the drive motor 31 is driven and the rotating body 33 rotates, the first pivot member 22 pivots about the first support shaft 22b by the connection relationship between the connecting member 34 and the first pivot member 22 (see
According to the second support mechanism 25 and the second pivot mechanism 35, when the drive motor 36 is driven and the rotating body 38 rotates, the first pivot member 27 pivots about the first support shaft 27b by the connection relationship between the connecting member 39 and the first pivot member 27 (see
As shown in
Each support mechanism 20 and 25, each pivot mechanism 30 and 35, and each end portion of the beam 11 is provided within a space closed by a box-shaped cover box 15 and a sheet member 16 having flexibility, and this configuration prevents the player Y from being injured. Further, a not shown appropriate shock absorbing member is winded on the outer circumferential portion of the beam 11, and the upper portion of the base 14 is covered with a not shown appropriate shock absorbing member, thereby, preventing the player Y from being injured when the player Y tumbles or falls down.
According to the playing device 1 of the embodiment configured as described above, like a balance beam, the player Y can play by, for example, walking or running on the outer circumferential surface of the beam 11 along the longitudinal direction while keeping his/her balance, while the first pivot members 22 and 27 of each support mechanism 20 and 25 are pivoted about their respective first pivot center axes by the pivot mechanisms 30 and 35 respectively, thereby, the both end portions of the beam 11 are displaced (moved) in the direction intersecting the longitudinal direction thereof.
Further, the second pivot members 23 and 28 of each support mechanism 20 and 25 are supported pivotably about their respective second pivot center axes by the first pivot members 22 and 27, respectively. Therefore, the second pivot members 23 and 28 pivot when the player Y cannot balance well in moving. Thereby, the beam 11 is displaced (moved) in the direction intersecting the longitudinal direction thereof.
In this way, according to the playing device 1 of the embodiment, each first pivot member 22 and 27 is pivoted by each pivot mechanism 30 and 35, and each second pivot member 23 and 28 pivots when the player Y cannot balance well. Thereby, the player Y can play while enjoying the feelings accompanying the combined motion of the pivoting of the first pivot members 22 and 27 by the pivot mechanisms 30 and 35 and the pivoting of the second pivot members 23 and 28 depending on the player Y's state of balance. As a result, compared with the above-described conventional playing device where the beam is fixed, it is possible to increase the difficulty in moving from one end side of the beam 11 to the other end side, to make the player Y play more happily, to develop the player Y's sense of balance to a high level, not to make the player Y bored by preventing the play in the playing device 1 from being monotonous, and to interest children.
Further, it is also possible to interest children around the playing device 1, who see the motion (displacement) of the beam 11 by each pivot mechanism 30 and 35, in playing with this playing device 1.
Thus, one embodiment of the present invention has been described above. However, specific modes in which the present invention can be realized are not limited thereto.
In the above embodiment, the beam 11 is configured by a tube-shaped member having a circular cross-sectional shape. However, the cross-sectional shape of the beam 11 is not particularly limited. For example, the beam 11 may be configured by a tube-shaped member having a rectangular cross-sectional shape, or a solid member having a circular or rectangular cross-sectional shape. Further, each pivot mechanism 30 and 35 is also not limited to the above-described configuration.
Further, in the above embodiment, as shown in
Further, as shown in
In addition, although not specifically shown in the drawings, it is also possible to omit the first pivot members 22 and 27 of each support mechanism 20 and 25, and each pivot mechanism 30 and 35, and to configure the playing device such that the second pivot members 23 and 28 are supported pivotably about their respective second pivot center axes by the support members 21 and 26, respectively. In this case, the beam 11 is displaced (moved) in the direction intersecting the longitudinal direction thereof only by the pivoting of the second pivot members 23 and 28 depending on the player Y's state of balance.
Further, as shown in
Further, each pivot mechanism 30 and 35 may be omitted, and as shown in
As shown in
According to this holding mechanism 41, when the first pivot members 22 and 27 pivot from their respective exact middle positions in the pivot direction thereof (such positions of the first pivot members 22 and 27 as the axis of the beam 11 is contained in the vertical plane containing the axis line of the first support shaft 22b) depending on the player Y's state of balance, they are replaced to their respective middle positions by biasing forces of the spring bodies 43.
Further, as shown in
According to this regulating mechanism 44, the first pivot members 22 and 27 are pivoted depending on the player Y's state of balance. When the amount of pivoting (an angle of tilt) exceeds a certain value, the first pivot members 22 and 27 come into contact with the contact members 46, thereby, the pivoting is regulated.
In
In the above embodiments, the beam 11 is configured so as to be displaced in the direction intersecting the longitudinal direction thereof by pivoting the first pivot members 22 and 27, or the second pivot members 23 and 28. However, they are not limited thereto. For example, the one end (the other end) or both end portions of the beam 11 may be disposed in a long hole which is formed with the longitudinal direction thereof along the direction intersecting the longitudinal direction of the beam 11 so as to be able to slide, or be adapted to be slid in the direction intersecting the longitudinal direction thereof by appropriate drive means such as a drive cylinder.
Further, in the above embodiments, the beam 11 is non-rotating. However, as shown in
According to this rotation drive mechanism 80, when the drive motor 81 is driven, its drive force is transmitted to the beam 11 via the first gear 82 and the second gear 83. Thereby, the beam 11 rotates about the axis thereof (the beam 11 is displaced in the direction intersecting the longitudinal direction thereof). In this way, by rotating the beam 11 about the axis thereof, the rotation of the beam 11 itself can be added to the above motion of the beam 11, thereby being able to make it more difficult for the player Y to move on the beam 11.
The beam 11 may be configured to rotate only in one direction, may also be configured to rotate in the forward and reverse directions. Further, in the playing devices shown in
In the above embodiments, the beam 11 is moved by pivoting the first pivot members 22 and 27, or the second pivot members 23 and 28. However, it is not limited thereto. The beam 11 may be moved (displaced in the direction intersecting the longitudinal direction of the beam 11) by pivoting the beam 11 itself
In this case, both end portions of beam 11 are supported pivotably about a pivot center axis parallel to the longitudinal direction thereof by a first support member 50 and a second member 51 which have a rectangular cross sectional shape and which are fixedly arranged on the upper surface of each mount 12 and 13, respectively.
Also in the playing device comprising such a beam 11, although not specifically shown in the drawings, the beam 11 may be pivoted about the pivot center axis by an appropriate pivot mechanism. Further, as shown in
Each of the holding mechanisms 52 is configured with: a support member 53 supported by each support member 50 and 51 below the beam 11; and two spring bodies 54 which are disposed on both sides of the pivot center axis such that their respective axes are directed in the up-and-down direction, and which are provided between the upper surface of each support member 53 and the lower surface of the beam 11. In this holding mechanism 52, when the beam 11 pivots from the exact middle position in the pivoting direction (such position as the upper surface of the beam 11 is horizontal) depending on the player Y's state of balance and the beam 11 pivots, the beam 11 is replaced to the middle position by biasing forces of the spring bodies 54.
Each of the regulating mechanisms 55 is configured with: a support member 56 supported by each support member 50 and 51 below the beam 11; and two contacting members 57 which are disposed on both sides of the pivot center axis and are vertically arranged on the upper surface of the support member 56. In this regulating mechanism 55, the beam 11 pivots depending on the player Y's state of balance. When the amount of pivoting (an angle of tilt) exceeds a certain value, the beam 11 comes into contact with the contacting members 57 and the pivoting of the beam 11 is regulated.
Like the first pivot members 22 and 27, each support member 50 and 51 may be configured to be pivotable about a pivot center axis parallel to the longitudinal direction of the beam 11, and to be pivoted by appropriate means or mechanism such as the pivot mechanisms 30 and 35. Further, in
In addition, as shown in
A first support mechanism 60 for supporting the one end of the beam 11 comprises: a support block 61 vertically arranged on the upper surface of the first mount 12; a support member 62 fixedly arranged on the side surface of the support block 61 on a second support mechanism 66 side; a first pivot member 63 supported pivotably about a horizontal first pivot center axis perpendicular to the longitudinal direction of the beam 11 by the support member 62; and a second pivot member 64 which is supported pivotably about a second pivot center axis parallel to the first pivot center axis by the first pivot member 63, and to which the one end of the beam 11 is connected.
The first pivot member 63 includes: a flat prate portion 63a which is formed in a flat plate and an elongate shape, and which is disposed such that its longitudinal direction is directed in the lateral direction; a first support shaft 63b which is fixedly arranged on the left end of the flat plate portion 63a and which is arranged co-axially with the first pivot center axis; and a second support shaft 63c which is fixedly arranged on the right end of the flat plate portion 63a, and which is arranged co-axially with the second pivot center axis. The first support shaft 63b is supported rotatably by the support member 62.
The second pivot member 64 includes: an engagement portion 64a which rotatably engages with the second support shaft 63c of the first pivot member 63; and a holding portion 64b which is formed below the engagement portion 64a for holding and fixing the one end of the beam 11.
On the other hand, the second support mechanism 66 for supporting the other end of the beam 11 includes two support members 67 disposed on the upper surface of the second mount 13 at a certain distance in the first pivot center axis direction; and a support shaft 68 which is put between the support members 67, and which is inserted into the long hole 11a of the beam 11.
Further, a drive mechanism 70 for displacing the one end of the beam 11 in the up-and-down direction includes: a drive motor 71; a support member 72 fixedly arranged on the side surface of the support block 61 on the second support mechanism 66 side for supporting the drive motor 71; and a rotating body 73 fixedly arranged on an output shaft of the drive motor 71; and a connecting member 74 for connecting the outer circumferential side of the rotating body 73 to between the right end and the left end of the first pivot member 63.
According to each support mechanism 60 and 66 and the drive mechanism 70 configured in this way, when the drive motor 71 is driven and the rotating body 73 rotates, the first pivot member 63 pivots about the first support shaft 63b by the connection relationship between the connecting member 74 and the first pivot member 63. Thereby, the one end of the beam 11 moves in the up-and-down direction, and the beam 11 pivots about the support shaft 68. At this time, the tilt generated by the pivoting of the beam 11 is allowed by the pivoting of the second pivot member 64 about the second support shaft 63c. Further, the movement of the beam 11 in the longitudinal direction thereof is allowed by the long hole 11a.
In the embodiment as shown in
In the playing device according to the above described variations, compared with the above conventional one in which the beam is fixed, it is possible to make the playing device more attractive by the motion of the beam 11, and a similar effect to the above can be obtained.
Industrial Applicability
As described in detail above, the present invention is preferably applicable as a playing device with which a player can perform more diversified play, and which can interest children.
