[0014] (Overview of playground equipment 1) Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an example of a perspective view of a playground equipment 1 according to this embodiment. FIG. 2 is an example of a perspective view of a fixed part 10, a swinging part 12, and a playground equipment connecting unit 20, with a portion A shown in FIG. 1 enlarged. FIG. 3 is an example of an exploded perspective view of the fixed part 10, the swinging part 12, and the playground equipment connecting unit 20, with a portion A shown in FIG. 1 enlarged. The playground equipment 1 shown in FIG. 1 is installed in, for example, a park or an event venue.

[0015] As shown in FIGS. 1 to 3, the play equipment 1 includes a fixed part 10, a swinging part 12 that is swingable relative to the fixed part 10, and a play equipment connection unit 20 that connects the fixed part 10 and the swinging part 12 together.

[0016] The fixed portion 10 corresponds to, for example, a support pillar, and in this embodiment, a plurality of supports are connected to form the framework of the play equipment 1. One of the plurality of fixed portions 10 is buried in the ground, and the entire play equipment 1 is fixed to the ground. A protruding piece 102 (see Figs. 2 and 3) is formed at a portion of the fixed portion 10 where the swinging portion 12 is fixed. The protruding piece 102 is formed in a plate shape. One end surface 102a of the protruding piece 102 is joined to the mounting surface 10a of the fixed portion 10. The one end surface 102a of the protruding piece 102 is formed in a rectangular shape, and the entire surface is joined to the mounting surface 10a of the fixed portion 10. The protruding piece 102 can be joined to the fixed portion 10 by welding, bolt fastening, or the like.

[0017] The protruding piece 102 has a lateral through hole (not shown). The axis of the lateral through hole is set parallel to the short direction of one end surface 102a of the protruding piece 102. The first support bolt 24 is rotatably inserted into the lateral through hole. The first support bolt 24 has a bolt axis that coincides with the axis of the lateral through hole, and supports the first connecting member 22 described below rotatably with the bolt axis as the rotation axis. That is, the first support bolt 24 supports the first connecting member 22 rotatably with an axis parallel to the mounting surface 10a (one end surface 102a) of the fixing part 10 as the first rotation axis (bolt axis). The other end surface 102b of the protruding piece 102 opposite to the one end surface 102a is formed in a curved shape with a curvature centered on the axis of the lateral through hole. As a result, the protruding piece 102 is formed in a shape that prevents contact with the protruding piece 102 when the first connecting member 22 described below rotates.

[0018] In this embodiment, the first rotation axis is parallel to the mounting surface 10a of the fixed part 10, but since the fixed part 10 is a spiral support (see FIG. 1), the mounting surface 10a of the fixed part 10 is curved and not flat in the strict sense. In contrast, the first rotation axis is a linear axis. Therefore, the above-mentioned "parallel to the mounting surface 10a of the fixed part 10" does not mean parallel in the strict sense, but can be interpreted as approximately parallel to the mounting surface 10a of the fixed part 10.

[0019] The swinging part 12 corresponds to, for example, a rope-like object or a long object such as a chain-like metal fitting for suspending a swing. In this embodiment, a plurality of swinging parts 12 are connected to the fixed part 10, and the plurality of swinging parts 12 form a mesh-like playground. For example, a metal fitting 14 (see FIG. 4) having an outer diameter larger than that of the swinging part 12 is extrapolated to the end of the swinging part 12 so as not to come off the swinging part 12.

[0020] The playground equipment connecting unit 20 connects the swinging part 12 to the fixed part 10. The playground equipment connecting unit 20 is provided between the fixed part 10 and one swinging part 12, and connects the two together so that the swinging part 12 can swing relative to the swinging part 12.

[0021] Since the playground equipment 1 according to this embodiment is a playground equipment for children to play with, it is necessary to guarantee the safety of the playground equipment 1 as a whole. In particular, since the playground equipment connecting unit 20 connects the fixed part 10 and the swinging part 12, it is necessary to pay close attention to prevent injuries to children. On the other hand, the playground equipment 1 according to this embodiment is often assembled at the installation site, and therefore it is necessary to improve the workability of the on-site work.

[0022] From this perspective, the play equipment 1 according to this embodiment and the play equipment connecting unit 20 used in the play equipment 1 make it possible to improve workability while taking safety into consideration. Hereinafter, the play equipment connecting unit 20 will be described in detail with reference to Figs. 2 to 5.

[0023] (Outline of playground equipment connection unit 20) FIG. 2 is an example of a perspective view of the playground equipment connecting unit 20. As shown in FIG. 2, the playground equipment connecting unit 20 includes a first connecting member 22, one end of which is rotatably connected to the fixed part 10 with an axis parallel to the mounting surface 10a of the fixed part 10 as the first rotation axis, and a second connecting member 30, one end of which (one end of the second connecting member 30) is rotatably connected to the other end of the first connecting member 22 with an axis perpendicular to the first rotation axis and parallel to the mounting surface 10a as the second rotation axis. As a result, the first connecting member 22 and the second connecting member 30 are configured such that the rotation directions of the first and second connecting members 22 and 30 are perpendicular to each other due to the first and second rotation axes. It is not essential that the first and second rotation axes are perpendicular to each other, and the first and second rotation axes may intersect at a predetermined angle. That is, it is not essential that the oscillating portion 12 oscillates in a direction perpendicular to the first rotation axis, and it may oscillate in a direction intersecting the first rotation axis.

[0024] (Playground equipment connection unit 20) Next, the above-mentioned components of the play equipment connection unit 20 will be described with reference to Figs.

[0025] (First connecting member 22) 3, the first connecting member 22 has a fitting groove 22a into which the protruding piece 102 is rotatably fitted, and an insertion hole (not shown) that is formed to correspond to the position of the lateral through hole of the protruding piece 102 and has a hole axis in the short direction of one end face 102a of the protruding piece 102 on both sides of the fitting groove 22a. After the first connecting member 22 is positioned so that the hole axes of the lateral through hole of the protruding piece 102 and the insertion hole of the first connecting member 22 coincide with each other, the first support bolt 23 is inserted from one side of the short direction of the insertion hole, and the first support nut 24 is screwed into the other side of the insertion hole, so that the first connecting member 22 is rotatably connected to the protruding piece 102 about the first rotation axis.

[0026] A rotation support portion 221 is formed on the swing portion 12 side (opposite side to the fixed portion 10 side) of the first connecting member 22. A vertical through hole 221a is formed in the rotation support portion 221. The rotation support portion 221 is formed in a flat plate shape having a circular outer shape centered on the hole axis of the vertical through hole 221a. A curved groove 221b is formed on one side and the other side in the thickness direction (hole axis direction of the vertical through hole 221a) of the rotation support portion 221. The curved groove 221b is formed in an arc shape with the hole axis (second rotation axis) of the vertical through hole 221a as the rotation axis. The curved groove 221b constitutes a rotation angle restriction mechanism described later. The hole axis of the vertical through hole 221a is set parallel to the longitudinal direction of one end surface 102a of the protruding piece portion 102. The vertical through hole 221a corresponds to the insertion holes 32a and 33a of the second connecting member 30. The hole axes of the vertical through hole 221a and the insertion holes 32a and 33a are perpendicular to the first rotation axis and coincide with the second rotation axis parallel to the mounting surface 10a of the fixing part 10. The second support bolt 35 is inserted into the vertical through hole 221a and the insertion holes 32a and 33a. The bolt axis of the second support bolt 35 coincides with the second rotation axis. As a result, the play equipment connecting unit 20 is connected to the rotation support part 221 of the first connecting member 22 by fastening the second support bolt 35 and the second support nut 34 so that the second connecting member 30 can rotate freely around the bolt axis.

[0027] (Second connecting member 30) The second connecting member 30 has one end on the fixed part 10 side rotatably connected to the rotation support part 221 of the first connecting member 22. When the second connecting member 30 is connected to the first connecting member 22, the one end on the fixed part 10 side has a hemispherical shape, and the other end opposite to the one end has a cylindrical shape, forming an outer shape of a rotating body. The axis connecting the center points of the one end and the other end of the second connecting member 30 is set to intersect with the hole axis of the vertical through hole 221a of the first connecting member 22 and the hole axis of the insertion holes 32a, 33a. In the following description, the axis connecting the center points of the one end and the other end of the second connecting member 30 is referred to as the swing-side longitudinal axis, and the axis perpendicular to the swing-side longitudinal axis and perpendicular to the second rotation axis is referred to as the swing-side short axis.

[0028] The second connecting member 30 has a two-piece structure in which the first accommodating connecting member 32 and the second accommodating connecting member 33 are assembled by overlapping them facing each other. Abutment surfaces 32c, 33c are formed on the end of the fixed part 10 side of the swing-side longitudinal axis of the first accommodating connecting member 32 and the second accommodating connecting member 33. The abutment surfaces 32c, 33c are adapted to slidably abut against one side and the other side of the rotation support part 221. Insertion holes 32a, 33a are formed in the center of the abutment surfaces 32c, 33c. The abutment surfaces 32c, 33c are formed in a semicircular shape centered on the hole axis of the insertion holes 32a, 33a, and are set to a size smaller than the radius of the rotation support part 221. As a result, when the second connecting member 30 is connected to the first connecting member 22, one end of the second connecting member 30 does not come into contact with the first connecting member 22. Further, the contact surfaces 32c, 33c are formed with protrusions 32b, 33b which are movably fitted into the curved grooves 221b, 221b of the rotation support portion 221. The protrusions 32b, 33b constitute a rotation angle restriction mechanism which will be described later.

[0029] (First receiving and connecting member 32) The first accommodating connecting member 32 has an engagement groove 323 at the end of the swing-side longitudinal axis opposite to the fixed portion 10 side. This engagement groove 323 is formed in two places, one end and the other end of the swing-side short axis, and is a groove into which an engagement piece 333 described below engages when the second connecting member 30 is in an assembled state. The first accommodating connecting member 32 has a first recess 324. This first recess 324 forms a housing portion capable of housing a part of the swing portion 12 between itself and a second recess 334 described below when the second connecting member 30 is in an assembled state.

[0030] Between the engagement grooves 323, 323 in the first recess 324, a recess 3241 (hereinafter, this recess will be referred to as the "first clamping portion 3241") having a smaller diameter than the first recess 324 is formed. This first clamping portion 3241 is a portion that clamps the swinging portion 12 between itself and a second clamping portion 3341 described later in an assembled state of the second connecting member 30. In addition, the first clamping portion 3241 is formed by a first swinging portion fixing wall 3242 so as to have a concave curved shape that follows the outer shape of the swinging portion 12. The first swinging portion fixing wall 3242 is abutted by a metal fitting 14 that is inserted on the end portion of the swinging portion 12, so that the swinging portion 12 does not come off the second connecting member 30.

[0031] A first slide surface 325 is formed on both sides of the swing-side short axis of the first recess 324. The first slide surface 325 is a surface parallel to the abutment surface 32c. In an assembled state of the second connecting member 30, the abutment surface 32c faces the abutment surface 33c of the second accommodating connecting member 33 via the rotation support portion 221, and the first slide surface 325 faces the second slide surface 335 of the second accommodating connecting member 33.

[0032] (Second housing connecting member 33) The second accommodating connecting member 33 has an engaging piece 333. This engaging piece 333 is formed at two locations, one at each end of the swing-side short shaft, and as described above, engages with the engaging groove 323 when the second connecting member 30 is in an assembled state. This allows the first accommodating connecting member 32 and the second accommodating connecting member 33 to be fixed together so that they do not separate from each other when the second connecting member 30 is in an assembled state.

[0033] The second accommodating connecting member 33 has a second recess 334 between the abutment surface 33c and the engagement piece 333. As described above, the second recess 334 forms an accommodating portion capable of accommodating a part of the oscillating portion 12 between itself and the first recess 324 when the second connecting member 30 is in an assembled state.

[0034] At the other end of the second recess 334 on the side of the swinging part 12 of the swinging side longitudinal axis, a recess 3341 (hereinafter, this recess is referred to as the "second clamping part 3341") having a smaller diameter than the second recess 334 is formed. As described above, this second clamping part 3341 is a part that clamps the swinging part 12 between itself and the first clamping part 3241 in the assembled state of the second connecting member 30. In addition, at the other end in the longitudinal direction of the second accommodating connecting member 33, a second swinging part fixing wall 3342 is formed against which the metal fitting 14 inserted on the end of the swinging part 12 abuts, similar to the first clamping part 3241, so that the swinging part 12 does not come off the second connecting member 30. Note that, in the assembled state of the second connecting member 30, the first clamping part 3241 and the second clamping part 3341 form an opening through which the swinging part 12 can pass. Furthermore, in the assembled state of the second connecting member 30, the first swinging part fixing wall 3242 and the second swinging part fixing wall 3342 form a wall in the circumferential direction that abuts against the metal fitting 14 so as to prevent the swinging part 12 from coming off the second connecting member 30. A second slide surface 335 is formed on the swing-side short axis of the second recess 334. As described above, this second slide surface 335 faces the first slide surface 325 in the assembled state of the second connecting member 30.

[0035] (Procedure for connecting the fixed part 10 and the swinging part 12) Next, a procedure for connecting the fixed part 10 and the oscillating part 12 using the playground equipment connecting unit 20 will be described. When connecting the fixed part 10 and the oscillating part 12 using the playground equipment connecting unit 20, first, the fitting groove 22a of the first connecting member 22 is fitted into the protruding piece 102, and the through hole of the protruding piece 102 is aligned with the insertion hole of the first connecting member 22, and the first support bolt 23 is inserted. Then, the first support nut 24 is screwed onto the tip of the first support bolt 23 and fastened, thereby connecting the first connecting member 22 to the protruding piece 102 in a freely rotatable manner.

[0036] Next, in a state where the metal fitting 14 attached to the end of the swinging part 12 is housed in the first recess 324, the first slide surface 325 and the second slide surface 335 are opposed to each other, and the second accommodating connecting member 33 is slid relative to the first accommodating connecting member 32. At this time, the second accommodating connecting member 33 is slid relative to the first accommodating connecting member 32 from the swinging part 12 side toward the fixed part 10 side. As a result, the engagement piece 333 engages with the engagement groove 323, and in the assembled state of the second connecting member 30, the first accommodating connecting member 32 and the second accommodating connecting member 33 can be fixed so that they do not separate, and the convex parts 32b, 33b of the abutment surfaces 32c, 33c can be movably fitted into the curved groove 221b of the rotation support part 221.

[0037] Thereafter, the second support bolt 35 is inserted through a communication hole formed by the insertion holes 32a, 33a of the first accommodating and connecting members 32, 33 and the vertical through hole 221a of the first connecting member 22, and the second support nut 34 is screwed onto the tip of the second support bolt 35, thereby rotatably connecting the second connecting member 30 to the first connecting member 22. As a result, in a state in which the fixed part 10 and the oscillating part 12 are connected, the metal fitting 14 of the oscillating part 12 can be accommodated in the accommodation part formed by the first recess 324 and the second recess 334 so as not to come out of the second connecting member 30.

[0038] In this way, according to the playground equipment connecting unit 20 of this embodiment, it is possible to connect the swinging part 12 to the fixed part 10 by a simple operation of simply opposing the first slide surface 325 and the second slide surface 335 and sliding the second accommodating connecting member 33 toward the fixed part 10 relative to the first accommodating connecting member 32. In particular, by using the playground equipment connecting unit 20 of this embodiment, the fixed part 10 and the swinging part 12 can be easily connected, which makes it possible to improve the efficiency of on-site work in which the playground equipment 1 is installed.

[0039] (Rotation angle restriction mechanism) Next, the rotation angle restriction mechanism will be described. The rotation angle restriction mechanism has curved grooves 221b, 221b formed on one side and the other side in the thickness direction (the hole axis direction of the vertical through hole 221a) of the rotation support part 221 of the first connection member 22, and protrusions 32b, 33b formed on the abutment surfaces 32c, 33c of the first and second housing connection members 32 and 33 and movably fitted into the curved grooves 221b, 221b of the rotation support part 221. The curved grooves 221b, 221b are formed in an arc shape along the rotation direction of the hole axis (second rotation axis) of the vertical through hole 221a. The rotation angle of the second connection member 30 relative to the first connection member 22 is restricted by the abutment of the ends of the curved grooves 221b, 221b in the arc direction with the protrusions 32b, 33b. As a result, in the playground equipment connecting unit 20, the rotation angle of the second connecting member 30 relative to the first connecting member 22 at the connecting portion between the first connecting member 22 and the second connecting member 30 is restricted by the curved grooves 221b, 221b and the protrusions 32b, 33b, and the first connecting member 22 and the second connecting member 30 are prevented from approaching each other due to excessive rotation. As a result, it is possible to prevent, for example, a child's fingers from being pinched, and it is excellent in terms of safety.

[0040] Specifically, as shown in FIG. 4, when the rotation angle of the posture of the play equipment connecting unit 20 in which the swing-side longitudinal axis of the second connecting member 30 perpendicularly intersects with the mounting surface 10a of the fixed part 10 is taken as the reference angle, the second connecting member 30 has a rotation range of 60 degrees in one direction to 60 degrees in the other direction from this reference angle around the second rotation axis, that is, a movable range of 120 degrees around the rotation angle of the reference angle, relative to the first connecting member 22. In this case, for example, as shown in FIG. 5, if there is no rotation angle limiting mechanism, the gap between the second connecting member 30 and the first connecting member 22 approaches 1.2 mm due to the rotation of the second connecting member 30, but if there is a rotation angle limiting mechanism, the approach of the second connecting member 30 and the first connecting member 22 due to the rotation can be stopped at the stage when the gap becomes large enough to insert a rod-shaped member (for example, a finger) with a diameter of 8 mm. Note that the movable range of 120 degrees around the rotation angle of the reference angle is an example. It is preferable that the range of motion be set arbitrarily depending on the diameter of the rod-shaped member that is expected to be inserted into the gap.

[0041] In the present embodiment, the curved grooves 221b, 221b are formed in the pivot support portion 221 of the first connecting member 22, and the convex portions 32b, 33b are formed in the abutting surfaces 32c, 33c of the first housing connecting member 32, but this is not limited thereto. For example, the convex portions 32b, 33b may be formed in the pivot support portion 221 of the first connecting member 22, and the curved grooves 221b, 221b may be formed in the abutting surfaces 32c, 33c of the first housing connecting member 32.
