JP-A-8-289162

  Children envisioned as users of the present invention are very interested in moving objects. Furthermore, the child is likely to be interested in unstable things. The term “unstable” as used herein means that, for example, the shape or position changes and the movement differs from that of a general structure. Therefore, if the structure provided with the unstable mechanism can be rotated, the child's interest can be maintained for a long time, and thus the above-mentioned guardian of the user has a high demand for such playground equipment.

  However, it is natural that the structure must be stable, and advanced technology is required to manufacture the unstable playground equipment. Therefore, rotating such a playground equipment is complicated to manufacture, maintain, etc., and playground equipment manufacturers are reluctant to rotate the unstable playground equipment. An object of the present invention is to provide a playground equipment device that performs the above unstable change with a simple structure.

  The present invention for achieving the above object is premised on a playground equipment comprising a playground equipment main body and a rotating base. The playground equipment main body includes a spring body and a climbing prevention member. The spring body is formed in a spiral shape, and the climbing prevention member is provided at the upper end of the spring body. A configuration may be adopted in which a spring support portion is disposed at the center of the spring body, and the spring body is supported by the spring support portion. By adopting the above configuration, the spring body portion moves up and down and tilts to the left and right. Therefore, when climbing on the spring body, the spring body portion tilts in an unexpected direction of the user. Therefore, it is possible to provide a playground equipment that keeps the user's interest for a long time.

  In the above configuration, the rotating base is formed by stacking the lower base and the upper rotating body with the central axis aligned. The lower base includes a lower substrate, a drive motor, and a caster that supports the upper rotating body. The drive motor is a motor arranged on the lower substrate and capable of rotating the upper rotating body, and the caster is provided at a position where the upper rotating body can rotate around the central axis. The casters are preferably provided on a predetermined circumference on the lower base.

  Or you may employ | adopt the following structures as a rotary base | substrate comprised by laminating | stacking a lower base | substrate and an upper rotary body by aligning a central axis. That is, the lower base includes a lower substrate, a drive motor, a crank, and a caster that supports the upper rotating body. The drive motor is a motor that is disposed on the lower substrate and is capable of rotationally driving the upper rotating body, and a crank is pivotally supported on a rotating shaft that is rotated by the drive motor. The caster is provided at a position where the upper rotating body can rotate around the central axis, and the playground equipment body rotates eccentrically together with the rotating base. The casters are preferably provided on a predetermined circumference on the lower base.

  Since the caster supports the load of the playground equipment main body, the caster supports the load in the vertical direction. Therefore, even if a plurality of users use the playground equipment at the same time, the rotating base can be rotated.

  In the above configuration (including a configuration in which a crank is pivotally supported), it is desirable that the caster is disposed on the lower substrate with the wheel facing up, and the upper rotating body is supported by the wheel of the caster. By disposing the caster with the wheels facing upward, a rotating base with smooth rotation can be configured. Further, it is possible to effectively prevent the caster from stepping on the wiring in the rotating base.

  In the above-described configuration, it is desirable to include a slip ring that supplies power to the play apparatus main body. Even if the rotary playground equipment is rotating, it is possible to supply electric power to an electric decoration member such as an LED provided in the rotary playground equipment. Further, a torque limiter may be provided that is attached to the rotation shaft of the drive motor and controls the drive torque of the rotation shaft to be within a predetermined value.

  It is also possible to employ a configuration in which the play equipment main body is disposed on the rotating base body in an inclined state. By arranging the playground equipment main body in an inclined state on the rotating base, it is possible to cause complicated rotation with a simple configuration.

  Further, the rotating base is configured by laminating the lower base and the upper rotating body with the central axis aligned, and adopts a configuration in which a small motor for rotating the playground equipment main body on the rotating base is provided in the rotating base. It doesn't matter. You may employ | adopt the structure which equips the said rotation base | substrate only with the said small motor.

The present invention presupposes a playground equipment comprising a playground equipment main body and a rotating base. The playground equipment main body includes a spring body and a climbing prevention member. The spring body is formed in a spiral shape, and the climbing prevention member is provided at the upper end of the spring body. A configuration may be adopted in which a support bar is arranged at the center of the spring body and the spring body is supported on the support bar.
By adopting the above configuration, the spring body portion moves up and down and tilts to the left and right. Therefore, when climbing on the spring body, the spring body portion tilts in an unexpected direction of the user. Therefore, it is possible to provide a playground equipment that keeps the user's interest for a long time.

Below, the playground equipment 100 of this invention is demonstrated with reference to drawings. FIG. 1 is a schematic diagram showing the overall configuration of the playground equipment 100 according to the present invention. FIG. 2 is a schematic diagram of the rotary base 200 used in the playground equipment 100 according to the present invention as viewed from above. Further, FIG. 3 to FIG. 6 are schematic views for explaining the rotary base 200 provided in the play equipment 100 of the present invention or the play equipment 100 provided with the rotary base 200. However, details of each part not directly related to the present invention are omitted. A description of the rotating base 200 will be given later.

  That is, as shown in FIG. 1, the playground equipment 100 of the present invention includes a playground equipment main body 110 and a rotating base 200. The playground equipment main body 110 is configured by forming a tubular body in a spiral shape. Iron, stainless steel, carbon, titanium and the like are suitably used as the material for the tubular body formed in the spiral shape. In this example, the iron pipe was formed in the above spiral shape. The tubular body formed in the spiral shape corresponds to the spring body 120 of the present invention. Instead of the tubular body, a steel material filled with contents may be used.

  The playground equipment main body 110 of the present invention includes a ball 130 as a climbing prevention means at the upper end of the helical tube. By providing the ball 130, the user (assuming an infant or a young child) is preferably prevented from climbing over a predetermined height.

  The playground equipment main body 110 configured as described above is installed on the rotating base 200 described later. That is, the rotary base 200 is fixed to the lower end of the spiral tube. As shown in FIG. 1B, a configuration is adopted in which a straight tubular body 140 is disposed as a spring support portion at the center of the helical tubular body, and the helical tubular body is fixed to the straight tubular body 140. It doesn't matter. Of course, a configuration in which the ball 130 is fixed to the upper end of the linear tube 140 may be adopted.

(Rotating substrate)
Next, the rotary base 200 provided in the playground equipment 100 of the present invention will be described with reference to the drawings. 2 to 6 are conceptual schematic diagrams of the rotary base 200 (including the playground equipment 100 including the rotary base 200). However, details of each part not directly related to the present invention are omitted.

  The rotating base 200 includes an upper rotating body 210 and a lower base 220. As shown in FIG. 2A, the upper rotating body 210 is a circular substrate, but may be rectangular or polygonal as long as there is no obstacle to rotation.

  As shown in FIG. 2B and FIG. 3, the lower base 220 includes a central gear 227, a drive motor 226 that drives the central gear 227, and casters 224. First, when the lower substrate 221 of the lower base body 220 (in the present invention, a circular shape is adopted but the shape is arbitrary) is viewed from above, the central gear 227 is disposed at a central position. Of course, the central gear 227 and the lower substrate 221 are arranged in a fixed state so that the rotational axis of the central gear 227 coincides with the central axis of the lower substrate 221. A drive motor 226 is arranged at a position where the central gear 227 can be rotationally driven. A roller chain is wound around the central gear 227 and the rotation shaft of the drive motor 226 so that the central gear 227 can be rotated by the drive motor 226. When the rotation shaft of the drive motor 226 rotates, the roller chain is The central gear 227 may be configured to rotate through.

  Further, a plurality of casters 224 are disposed on the lower base 220 on the same plane as the central gear 227 and the drive motor 226. The caster 224 employs a configuration in which the caster 224 is disposed on the lower base with the wheel portion of the caster 224 facing up. The plurality of casters 224 are arranged such that the opposite casters 224 are symmetrical with respect to the center of the lower base 220, and the adjacent casters 224 are equidistant. In the present embodiment, a configuration in which the wheel portion of the caster 224 is on top is employed. Since the wheels of the casters 224 are facing upward, the casters 224 do not step on the wiring or the like in the rotating base 200. Of course, you may employ | adopt the structure arrange | positioned with the wheel part of the said caster facing up.

  As will be described later, when the upper rotating body 210 and the lower base body 220 are combined, an annular rail (not shown) may be provided at a position where the caster 224 contacts the upper rotating body 210. The caster 224 rotates while being in contact with the rail, so that the upper rotating body 210 rotates according to the rotation of the caster 224. Therefore, in the present invention, the wheels of the casters 224 of the lower base 220 support the upper rotating body 210. In addition, as described above, a configuration in which the wheel portion of the caster is placed downward may be employed.

Next, the upper rotating body 210 and the lower base body 220 are combined. First, the lower base 220 is placed on the floor surface with the surface on which the casters 224, the central gear 227, and the drive motor 226 are placed facing up. Then, the upper rotating body 210 is laminated on the lower base 220 so that the centers of the lower substrate 221 and the upper rotating body 210 overlap. At this time, the play equipment 100 of the present invention is configured by fitting or fixing the central gear 227 to the upper rotating body 210 so that the upper rotating body 210 rotates when the central gear 227 of the lower base body 220 rotates. To do. For maintenance, it is desirable that the central gear 227 is detachably fitted to the upper rotating body 210. The shape of the upper rotating body 210 may be any shape as long as the playground equipment main body 110 can be disposed, and various types of substrates such as a rectangular shape, a polygonal shape, and a circular shape can be attached.
Further, the drive motor 226 may be configured such that the rotational speed is controlled by a control unit (not shown). The control unit stores an optimum rotation number in advance, and a configuration in which the drive motor 226 is rotationally driven based on the rotation number can be employed. A switch (not shown) for operating the drive motor 226 may be provided on the rotating base 200 so that the rotational speed of the drive motor 226 can be controlled by the switch.

(Embodiment 2)
By configuring the rotary base 200 used in the first embodiment as follows, it is possible to configure the playground equipment 100 that rotates eccentrically. In addition, except the eccentric shaft mentioned later, the same structure as the playground equipment apparatus 100 demonstrated in Embodiment 1 is employ | adopted. Therefore, illustration and explanation of the configuration other than the eccentric shaft are saved.

  As shown in FIGS. 4 and 5, an eccentric shaft described later is used as the rotation shaft of the drive motor 226. That is, as shown in FIG. 4 and FIG. 5, the drive motor 226 is provided with an eccentric shaft (for example, a crank 228) having a handle connecting an axis shifted by a predetermined distance with respect to the rotation shaft of the drive motor 226. Thus, the rotation axis of the drive motor can be configured to be shifted within a predetermined range.

  That is, one end of the crank 228 rotates on the same axis as the rotation axis of the drive motor 226, and the other end of the crank 228 rotates eccentrically with respect to the rotation axis (with the rotation axis shifted). Means rotating). Of course, it goes without saying that a switch (not shown) for operating the drive motor 226 is provided on the rotary base 200. You may comprise so that the rotational speed of the drive motor 226 can be controlled with the said switch. Of course, the rotating base 200 shown in FIGS. 4 and 5 includes an upper rotating body 210 and a lower base 220. The upper rotating body 210 is a circular substrate, and the lower base body 220 includes a drive motor 226 that drives the crank 228 and a plurality of casters 224, and each caster 224 supports the upper rotating body 210. Needless to say.

  A restricting means 229 for restricting the rotation of the upper rotating body 210 may be provided. The regulating means 229 is an elastic body (a rubber, a spring or the like is preferably used) that couples the lower substrate 221 on which the drive motor 226 is disposed and the upper rotating body 210. The restricting means 229 may be arranged in any manner as long as it can be configured to restrict the rotation of the upper rotating body 210. In this embodiment, as shown in FIGS. 4B and 4C, the restriction means 229 is disposed on the lower surface of the upper rotating body 210 from the vicinity of the drive motor 226 disposed on the lower substrate 221. adopt. A configuration in which the restriction means 229 is arranged in the vertical direction from the lower substrate 221 may be adopted, or may be arranged obliquely from the lower substrate 221. Since the upper rotating body 210 is restricted from rotating by the restricting means 229, the upper rotating body 210 rotates around the rotation axis of the drive motor 226 while swinging.

(Other)
In the second embodiment, a configuration in which the upper rotating body 210 is horizontally attached to one end of the crank 228 (the other end is attached to the rotating shaft of the drive motor 226) is employed. On the other hand, the structure attached in the state which inclined the toy equipment main body 110 can be employ | adopted.

  FIG. 7 shows a configuration in which an inclined plate 230 is provided on the upper rotating body 210 and the playground equipment main body 110 is disposed on the upper rotating body 210 in an inclined state. Also in this case, the rotation shaft of the drive motor 226 may be the rotation shaft used in the first embodiment (see FIG. 6A), or the crank 228 used in the second embodiment may be used. It does not matter (see FIG. 6B). Since the configuration other than the configuration in which the playground equipment main body 110 is attached at an angle is the same as in the first and second embodiments, description and illustration are omitted.

  An overload protection means (for example, a torque limiter) that protects the overload of the drive motor 226 provided in the rotary base 200 (hereinafter, including the case where the crank 228 is provided and not provided) is provided as the drive motor. You may attach to the rotating shaft of 226 or the said crank 228. FIG. As described above, since the playground equipment main body 110 is arranged above the drive motor 226, a load corresponding to the weight of the user who wants to play is applied to the drive motor 226. When a predetermined load or more is applied to the drive motor 226, the above-described overload protection unit can detect the load and cause the drive motor 226 to idle.

  That is, for example, a torque limiter that protects the drive motor 226 from excessive torque and a torque sensor that detects the rotational torque are provided between the output shaft (rotary shaft) of the drive motor 226 and the central gear 227. As the torque sensor, a contact type torque sensor may be used, or a non-contact type torque sensor may be used. When the torque detected by the torque sensor exceeds the expected range, the rotational power from the drive motor 226 is not transmitted to the central gear 227 by the torque limiter.

Alternatively, a configuration may be adopted in which when the load is applied by inverter control and a current of a predetermined value or more flows in the drive motor, the current to the drive motor is cut off.
Furthermore, a slip ring (not shown) may be provided in the play equipment 100, and electric power may be supplied to an electrical decoration member (for example, an LED ribbon provided on the outer surface of the play equipment) by the slip ring. By using the slip ring as the power supply means, even if the playground equipment 100 rotates, there is no twisting of the wiring and power can be supplied.

  As shown in FIG. 7, a configuration may be adopted in which the rotary base 200 is further provided with a small motor 240 that rotates the play equipment main body 110 on the rotary base 200. Alternatively, as shown in FIG. 8, a configuration in which the rotary base 200 is provided with only the small motor 240 may be employed.

The present invention presupposes a playground equipment comprising a playground equipment main body and a rotating base. The playground equipment main body includes a spring body and a climbing prevention member. The spring body is formed in a spiral shape, and the climbing prevention member is provided at the upper end of the spring body. A configuration may be adopted in which a support bar is arranged at the center of the spring body and the spring body is supported on the support bar.
By adopting the above configuration, the spring body portion moves up and down and tilts to the left and right. Therefore, when climbing on the spring body, the spring body portion tilts in an unexpected direction of the user. Therefore, it is possible to provide a playground equipment that keeps the user's interest for a long time, and its industrial applicability is great.
