Description

  The present invention relates to an indoor foldable jungle gym.

  The present applicant previously proposed utility model registration Nos. 3097851, 3100900, and 3102074 as indoor jungle gyms that can be stored in a small flat folded state into a narrow closet of a veranda in an apartment house. .

Among them, if the utility model registration No. 3100900 is cited as a representative example, this intervenes at the intersection that forms an inverted T-shape in front view in order to prevent the jungle gym in the deployed use state from tipping forward and backward. A total of four grounding boards (E) are attached to the first fixed pipe joint (J1) in a crossing state straddling from above, and a jungle gym is provided by a stay stay (24) of each grounding board (E). It is designed to give a tension resistance against the above falling.
Utility Model Registration No. 3097851 Utility Model Registration No. 3100900 Utility Model Registration No. 3102074

  However, the registered utility model grounding board (E) does not have a sufficient weight as a hard synthetic resin product, and the arc-shaped cover pieces (22L) (22R) forming the same have a certain length (L4). ), The fixed length (L5) of the stay stay (24) is too small compared to the length of the jungle gym and the horizontal length of the horizontal bone pipe (X) (L1). Since it is narrow, it cannot exert a full resistance to tumbling of the jungle gym and is inferior in stability in its deployed and used state.

  That is, when an infant climbs from the front or rear to the upper cube frame (C) (C1) (C2) of the jungle gym, or swings in the climbed state, there is a risk of falling forward or backward, As shown in FIGS. 44 and 45, this becomes more prominent as the height of the jungle gym becomes higher, and the infant cannot withstand severe usage.

  In addition, since the total of four grounding boards (E) are literally grounding boards and do not exhibit other special functions, there is a problem that the commercial value of the jungle gym cannot be improved.

  The present invention aims to improve such problems, and in order to achieve the object, in claim 1, a plurality of vertical horizontal bone pipes, a plurality of horizontal horizontal bone pipes and a plurality of vertical bone pipes are provided.

  While the first to fourth fixed pipe joints of various orientation forms corresponding to the intersection of the cube frame are respectively press-fitted and integrated into the end of the horizontal horizontal bone pipe and the end of the vertical bone pipe forming the cube frame,

  Similarly, one type of rotating pipe joint is press-fitted and integrated into both ends of the vertical and horizontal bone pipes that also form a cubic frame.

  In an indoor foldable jungle gym in which each pivot pipe joint is pivotally connected to each of the first to fourth fixed pipe joints so as to be pivotable by about 90 degrees by a vertical axis.

  Fold the front ground leg frame to one of the lower left and right cube frames and the rear ground leg frame to the other side by about 90 degrees with the vertical and horizontal bone pipes as pivot points. Pivot,

  A pair of the front and rear grounding leg frames are maintained in a grounding use state in which the pair of front and rear grounding leg frames are projected from the lower left and right cube frames, thereby giving a tension resistance against a forward and backward fall.

  Further, in claim 2, similarly, a plurality of vertical horizontal bone pipes, a plurality of horizontal horizontal bone pipes and a plurality of vertical bone pipes are used to form a lower central cube frame and a pair of lower left and right side parallel to both sides thereof. A three-dimensional framework is formed from the right cube frame and at least one upper cube frame stacked on these lower cube frames,

  While the first to fourth fixed pipe joints of various orientation forms corresponding to the intersection of the cube frame are respectively press-fitted and integrated into the end of the horizontal horizontal bone pipe and the end of the vertical bone pipe forming the cube frame,

  Similarly, one type of rotating pipe joint is press-fitted and integrated into both ends of a vertical and horizontal bone pipe that also forms a cubic frame.

  In an indoor foldable jungle gym in which each pivot pipe joint is pivotally connected to each of the first to fourth fixed pipe joints so as to be pivotable by about 90 degrees by a vertical axis.

  A pair of front and rear grounding leg frames are pivotally attached to the lower central cube frame so that both the vertical and horizontal bone pipes can be folded by about 90 degrees.

  A pair of the front and rear grounding leg frames is maintained in a grounding use state in which the pair of front and rear grounding leg frames is projected from the lower center cube frame, thereby giving a tensile resistance against a fall in the front-rear direction.

  In claim 3 dependent on claim 1 or 2, each of the front and rear grounding leg frames has a total of two vertical horizontal link pipes shorter than the vertical horizontal bone pipe, and a total of four horizontal horizontal link pipes. And, from the total of two vertical link pipes that maintain a narrower distance than the left and right mutual spacing between the horizontal and horizontal link pipes, the three-dimensional framework as a parallel link mechanism that forms a symmetrical U-shape in side view,

  A base end portion of the horizontal and horizontal link pipes is pivotally attached to a midway portion of the vertical and horizontal bone pipes in the lower left and right cube frames or the lower central cube frame, respectively, in a undulating manner.

  Further, in claim 4 that is dependent on claim 3, the rotary pipe joint that is press-fitted and integrated into the base end portion of the horizontal and horizontal link pipes, and the press-fitted and integrated piece that is inserted into the middle part of the vertical and horizontal bone pipes. The fixed pipe joint is pivotally connected by a horizontal axis parallel to the vertical horizontal bone pipe,

  A rotation-preventing cover sleeve which can cover the pivot connection portion is slidably inserted into the horizontal and horizontal link pipes and is fitted.

  Similarly, in claim 5, which is dependent on claim 3, the tip of the horizontal horizontal link pipe and the vertical horizontal link pipe are connected and integrated by a fixed pipe joint, and the rotary pipe joint is press-fitted into the lower end of the vertical link pipe. Integrated,

  The fixed pipe joint and the rotating pipe joint are pivotally connected by a horizontal axis parallel to the vertical and horizontal link pipe,

  Further, in claim 6, which is dependent on claim 3, the pair of the slide and the staircase facing each other is detachably locked from above to either or both of the horizontal horizontal link pipes in the front and rear grounding leg frames. Let the slide and the staircase be kept in contact with the ground at a certain inclination angle,

  By inserting a corresponding rectangular top plate into a rectangular frame in plan view partitioned from the horizontal and horizontal link pipes and the horizontal and horizontal link pipes from above, the slide and the stairs can be connected. It is characterized by pressing and fixing at the same time.

  According to the above configuration of claim 1, the pair of the front ground leg frame projecting from either one of the lower left and right cube frames forming the jungle gym and the rear ground leg frame projecting from the remaining other is in a grounding use state. In this case, since the jungle gym falls effectively forward or backward, it exerts an effective tension resistance, so it can endure the severe use of infants and can significantly improve safety.

  Moreover, the front and rear grounding leg frames can be folded by about 90 degrees with the vertical and horizontal bone pipes of the lower left and right cube frames as pivot points, and the entire jungle gym including the lower left and right cube frames.

(R2-R2) The comrades located on (the downward slanting diagonal line in FIG. 4) are in a state of being directed toward the in-corner side (inward turning direction), and thereby the lower left-side cube frame (B1) and Either one of the lower right cube frame (B2) Folding flattened as the state of being closely contacted with the front surface of the lower central cube frame (A) folded first, and the other side being folded and flattened as the state of being closely contacted with the rear surface of the lower central cube frame (A). -ing

  Regarding the arrangement direction of the vertical horizontal bone pipe (Y), the rotation allowable surface (4) on the side of the rotation pipe joint (J) press-fitted and integrated into both right and left ends is as shown in FIG. The vertical and horizontal bone pipes (Y) that are reversed in the front-rear direction when viewed from a flat plane, as suggested by the whole of FIG. 4, are the lower center cube frame (A), the upper cube frame (C), and the lower left cube. In the framework of the frame (B1) and the lower right cubic frame (B2), the front row and the back row are alternately reversed in the left and right direction, and the staggered arrangement state is also reversed in the left and right direction between the front row and the rear row. It can be easily defined by using it.

  Next, (S) is a rotation prevention cover sleeve made of hard synthetic resin. The rotation pipe joint (J) and the first to fourth fixed pipe joints (J1) (J2) (J3) (J4) As a cylindrical shape having a fixed length (L3) (for example, about 35 mm) that can cover the pivot connecting portion, the sleeve is inserted and slidably inserted into the vertical and horizontal bone pipe (Y) in advance.

  In this case, in the jungle gym of the basic embodiment shown in FIGS. 1 to 4, the third and fourth fixed pipe joints are respectively provided on the upper side of the lower left and right cube frames (B1) and (B2) and the upper side of the upper cube frame (C). (J3) In consideration of the fact that it is most likely to be deformed and deformed from the intersection where (J4) intervenes, only the parallel vertical and horizontal bone pipes (Y) on the upper side are fitted with a rotation prevention cover sleeve (S). From the vertical horizontal bone pipe (Y), the connecting plate piece (2) of the rotating pipe joint (J) and the connecting fork plate piece (27L) of the third and fourth fixed pipe joints (J3) (J4) ( 27R), the pivoting connection portion between the connecting plate piece (2) and the connecting fork plate pieces (27L) (27R) is covered.

As a result, in the deployed use state of the jungle gym as shown in FIGS. 1 to 4, the rotary pipe joint (J) attached to the left and right ends of the vertical and horizontal bone pipe (Y) is covered by the cover sleeve (S). The third and fourth fixed pipe joints (J3) and (J4) are fixed and maintained in a non-rotatable manner, and a square in plan view is formed from the vertical horizontal bone pipe (Y) and the horizontal horizontal bone pipe (X). Even if a strong external force is applied along the diagonal line, there is no risk of unauthorized distortion to the diamond shape, and the safety of the infant can be ensured.

  For the folding jungle gym with the above configuration, either one of the lower left and right cubic frames (B1) and (B2) has a front ground leg in order to prevent the risk of falling forward or backward in the deployed use state. As shown in FIGS. 28 and 29, both the frame (F) and the rear grounding leg frame (R) on the other side are folded about 90 degrees with the longitudinal and horizontal bone pipes (Y) as pivot points. The pair of front and rear grounding leg frames (F) and (R) are kept in a grounding state in which they project from the lower left and right cubic frames (B1) and (B2) to the front and rear, respectively. As a result, the jungle gym can be provided with an effective tension resistance against the fall.

  The pair of front and rear grounding leg frames (F) and (R) are symmetrically U-shaped in side view, but the frame structure is identical to each other, so only one of them is now extracted. Each of the grounding leg frames (F) and (R) will be described based on the enlarged views of FIGS. 30 to 36. The vertical horizontal link pipe (Y1) is shorter than the vertical horizontal bone pipe (Y). ), A total of two vertical link pipes (Z1) the same as the vertical bone pipe (Z), and a total of four horizontal horizontal bone pipes (X), preferably the same horizontal horizontal link pipe (X1) To a total of four first rotating pipe joints (E1), a total of two second rotating pipe joints (E2), a total of two third rotating pipe joints (E3), a fifth fixed pipe joint ( A total of four of J5), a total of two of the sixth fixed pipe joints (J6) and a seventh fixed pipe joint (J7) Are used in a pivotal connection to form an overall parallel link mechanism, and the base ends of the four horizontal and horizontal link pipes (X1) are the lower left and right cube frames. (B1) It is pivotally attached to the vertical and horizontal bone pipe (Y) of (B2) so as to be able to turn up and down by about 90 degrees from the front or rear.

  That is, the first rotary pipe joint (E1) is press-fitted and integrated at the base end of the horizontal and horizontal link pipe (X1), while forming the lower left and right cube frames (B1) and (B2). Fifth fixed pipe joints (J5) are press-fitted and integrated at both left and right ends of the vertical horizontal bone pipe (Y), and connecting plate pieces projecting from the respective first rotating pipe joints (E1) ( 14) and a connecting fork plate piece (15L) (15R) projecting correspondingly from each fifth fixed pipe joint (J5) via a horizontal axis (18) parallel to the longitudinal horizontal bone pipe (Y) It is pivotally connected.

  Moreover, the above-described rotation prevention cover sleeve (S) is inserted into the horizontal and horizontal link pipes (X1) of the front and rear grounding leg frames (F) and (R) so as to be slidable in advance. It extends so as to straddle the connecting plate piece (14) of the first rotating pipe joint (E1) and the connecting fork plate pieces (15L) (15R) of the fifth fixed pipe joint (J5). By operating it, it is possible to cover the pivot connecting portion between the connecting plate piece (14) and the connecting fork plate pieces (15L) (15R).

  In this case, the first rotating pipe joint (E1) is a hard synthetic resin product having substantially the same form as the rotating pipe joint (J) shown in FIG. 6, and the fifth rotating pipe joint (J5) is a figure. The connecting fork plate pieces (15L) and (15R) form a substantially T-shape in plan view in which the connecting fork plate pieces (15L) and (15R) project at right angles from the left and right sides of the leg cylinders (19) and the connecting plate pieces (20). As a hard synthetic resin product, the connecting plate piece (20) is pivoted to the first to fourth fixed pipe joints (J1), (J2), (J3), and (J4) described above, each also serving as a vertical axis (P). It is worn. As a result, the jungle gym is folded without any hindrance with the vertical axis (P) as a pivot, and the grounded leg frames (F) and (R) follow the lower left and right cube frames (B1) and (B2). It will be possible.

  In addition, among the four horizontal horizontal link pipes (X1) in total, the sixth fixed pipe joint (J6) is press-fitted and integrated at the distal end portion of the upper horizontal horizontal link pipe (X1) parallel as a pair of left and right. On the other hand, another seventh fixed pipe joint (J7) is press-fitted and integrated at the tip of the lower horizontal link pipe (X1) which is also parallel as a pair of left and right.

  In this regard, the sixth fixed pipe joint (J6) is a rigid L-shaped plan view from a long leg tube (21) and a short leg tube (22) that intersect at right angles as shown in FIGS. Compared to this, the seventh fixed pipe joint (J7) has a long leg tube (23) and a short leg tube (24) in plan view as shown in FIGS. A rigid synthetic resin that is L-shaped but has a fork plate piece (25L) (25R) projecting from the middle part of its long leg tube (23) in the opposite direction to the short leg tube (24). It is a product.

  Further, a second rotating pipe joint (E2) is press-fitted into the upper end portion of the vertical link pipe (Z1), and a third rotating pipe joint (E3) is similarly press-fitted into the lower end portion of the vertical link pipe (Z1). Has been.

  On the other hand, the second rotating pipe joint (E2) is a hard synthetic resin product having a T-shape in a front view where the cover tube (28) and the leg tube (29) cross at right angles as shown in FIGS. On the other hand, the third rotating pipe joint (E3) is also a hard synthetic resin product, but the upper and lower portions of the leg tube (30) and the connecting plate piece (31) as shown in FIGS. It is a single letter type engraved as a cylinder (32).

  A long leg tube (21) parallel to the longitudinal and horizontal bone pipe (Y) in the sixth fixed pipe joint (J6) has a second rotating pipe joint (attached to the upper end of the vertical link pipe (Z1)). E2) and a short vertical horizontal link pipe (Y1) are inserted and fitted, and in the seventh fixed pipe joint (J7), a long leg tube (23) parallel to the vertical horizontal bone pipe (Y) is also provided. A short vertical and horizontal link pipe (Y1) is inserted and fitted.

  Moreover, the connecting plate piece (31) protruding from the third rotating pipe joint (E3) attached to the lower end of the vertical link pipe (Z1) and the seventh fixed pipe joint (J7) are correspondingly extended. The connecting fork plate pieces (25L) and (25R) are pivotally connected via a horizontal shaft (33) which is also parallel to the longitudinal and horizontal bone pipe (Y).

  In that case, the cover cylinder (28) of the second rotating pipe joint (E2) attached to the upper end of the vertical link pipe (Z1) is in contrast to the long leg cylinder (21) of the sixth fixed pipe joint (J6). As a result, the grounding leg frame (F) (R) is a left and right cube frame (B1) (B1) as a parallel link mechanism that is three-dimensionally framed in a U shape as viewed from the side. About 90 degrees can be swung around the fulcrum of the vertical and horizontal bone pipe (Y) forming B2).

  (34) is a cylindrical lock nut that is screwed and fastened to the threaded cylinder (32) of the third rotating pipe joint (E3), as shown in FIGS. By screwing the 7 fixed pipe joint (J7) against the connecting fork plate pieces (25L) (25R), the lower horizontal link pipe (X1) and the vertical link pipe (Z1) are moved to about 90 It can be fixed and maintained in the unfolded state where it is crossed only once, and the grounding leg frame (F) (R) can be folded by screwing the lock nut (34).

  For one or both of the front and rear grounding leg frames (F) and (R), as shown in the unfolded use state of FIGS. 58 to 60, the slide (35), the staircase (36) and the top plate ( 37) is preferably detachably locked to give a jungle gym an interesting change in use and added value.

  That is, the slide (35) is integrally molded from a hard synthetic resin so as to have a substantially U-shaped cross section, and the front and rear grounding leg frames (35a) having upper ends bent in an arc shape are used as the slide hook (35). F) A horizontal and horizontal link pipe (X1) of (R) is detachably locked from above, and a pair of claw receiving ports (35b) arranged in parallel with the locking hook (35a). Is cut out.

  Also, the staircase (36) is made of a hard synthetic resin, and the upper and lower ends of the staircase (36) serve as a hook hook (36a) that is bent in an arc shape. A pair of claw receiving openings (36b) are also cut out in parallel with the locking hook (36a).

  As shown in FIG. 59, the top plate (37) is molded from a hard synthetic resin so that the front and rear grounding leg frames (F) and (R) can be covered with a rectangle from above. As shown in FIG. 60, the locking claw (37a) that hangs continuously from the periphery of the front and rear grounding leg frames (F) and (R) is first connected to the horizontal horizontal link pipe (X1). Through the claw receiving port (35b) of the slide (35) locked from above and the claw receiving port (36b) of the stairs (36) locked from above to the horizontal horizontal link pipe (X1). The front and rear grounding leg frames (F) and (R) are detachably locked to the vertical and horizontal link pipes (Y1).

  For this reason, in combination with the elastic force of the locking claw (37a), the pair of opposite sides of the slide (35) and the staircase (36) are connected to the front and rear grounding leg frames (F) by the top plate (37). (R) can be pressed and fixed simultaneously from above, and the front and rear grounding leg frames (F) and (R) can be extended to the lower left and right cube frames (B1) and (B2). Can be prevented from being accidentally folded and flattened, and can also be prevented from being distorted and deformed into an illegal rhombus in plan view.

  When the slide (35), the stairs (36), and the top plate (37) are used for locking, the above-described second rotating pipe (E2) is a cross-shaped front view as shown in FIGS. The second rotary pipe joint (E2 ') is used in place of the second rotary pipe joint (E2'), and is press-fitted and integrated into the upper end of the vertical link pipe (Z1). A leg tube (39) of a handrail (38) made of hard synthetic resin such as 61, 62 is inserted and fixed. This will improve infant safety and convenience in use.

  28 to 31 show the unfolded and used state of the jungle gym according to the present invention. From the lower left and right cubic frames (B1) and (B2), the front ground leg frame (F) and the rear ground leg frame (R ) Protrudes forward and rearward and is in contact with the ground, so there is no risk that the jungle gym will fall forward or backward due to its resistance to tension.

  Therefore, when the jungle gym is folded from the unfolded use state, the pivot joints of the rotating pipe joint (J) and the third and fourth fixed pipe joints (J3) (J4) are respectively covered. The movement-preventing cover sleeve (S) is retracted onto the vertical and horizontal bone pipes (Y) to expose the pivotal connecting portion between the connecting plate piece (2) and the connecting fork plate pieces (27L) (27R). Keep in state.

  Further, the rotation-preventing cover sleeves (S) respectively covered on the pivot joints of the first rotating pipe joint (E1) and the fifth fixed pipe joint (J5) are connected to the front and rear grounding legs. The frame (F) (R) is retracted onto the horizontal and horizontal link pipe (X1), and the pivotally connected portion between the connecting plate piece (14) and the connecting fork plate pieces (15L) (15R) is exposed. keep.

  Further, the lock nut (34) pressed against the connecting fork plate pieces (25L) (25R) of the seventh fixed pipe joint (J7) is connected to the third rotating pipe joint (E3) as shown in FIGS. ) And the connecting plate piece (31) of the third rotating pipe joint (E3) and the connecting fork plate pieces (25L) (25R). Also keep it exposed.

  Needless to say, if the slide (35), the stairs (36), and the top plate (37) are attached and used, they must be removed.

  Then, the front and rear grounding leg frames (F) (R) attached to the lower left and right cubic frames (B1) and (B2) as the grounding use state are as shown in FIGS. By pulling up a pair of vertical and horizontal bone pipes (Y) as pivot points, the lower left and right cube frames (B1) and (B2) are flattened into a folded state in close contact with the front and rear surfaces, respectively.

  Next, the upper cubic frame (C) and the lower central cubic frame (A), which are still three-dimensionally framed into a square in plan view, are rotated about the vertical axes (P) scattered in the four corners. It is closed together as a fulcrum.

  Then, the adjacent vertical horizontal bone pipe (Y) and horizontal horizontal bone pipe (X) that form the upper cube frame (C) and the lower central cube frame (A) go through the middle process of FIG. One of the lower left and right cube frames (B1) and (B2) that are in a folded state closely parallel to each other as shown in FIGS. However, the other side (the lower left cube frame in the figure) approaches the rear surface of the lower central cube frame (A), respectively, to the front surface of the lower central cube frame (A) folded first. It becomes a relationship.

  Therefore, by continuously closing the lower left and right cube frames (B1) and (B2) separately as shown in FIGS. 66 to 68 and 69, with the vertical axes (P) at the four corners as the rotation fulcrum, The vertical horizontal bone pipe (Y) and the horizontal horizontal bone pipe (X) adjacent to each other are folded and flattened so as to be in close contact with each other and in close contact with the front and rear surfaces of the lower central cube frame (A). It ’s fine.

  The overall folded state of the jungle gym is as shown in FIGS. 67 to 69. As is clear from this, the connecting fork plate pieces (7L) (7R) of the first to fourth fixed pipe joints (J1) to (J4) are clear. ) (17L), (17R), (27L), and (27R) are formed so as to protrude by the thickness (D) of the vertical and horizontal bone pipe (Y). The vertical horizontal bone pipe (Y) and the horizontal horizontal bone pipe (X) that form the upper cube frame (C) and the lower left and right cube frames (B1) and (B2) are obtained in an extremely flat folded state. It is done.

  The vertical horizontal link pipe (Y1) of the front and rear grounding leg frames (F) (R) attached to the lower left and right cubic frames (B1) and (B2) is the vertical horizontal bone pipe (Y The vertical link pipes (Z1) of the front and rear grounding leg frames (F) and (R) are standing at a distance narrower than the horizontal distance between the horizontal and horizontal link pipes (X1). Since the base end portion of the horizontal horizontal link pipe (X1) is pivotally attached to the middle portion of the vertical horizontal bone pipe (Y), the front and rear grounding leg frames (F) (R) are also illustrated. As is apparent from 63 to 65, each of the link pipes (X1) (Y1) (Z1) can be folded into a flat state having a thickness substantially corresponding to the thickness (D).

  As a result, the working length of the slide (35) is made to be equal to or less than the stacking height of the lower center cube frame (A) and the upper cube frame (C). In addition to being able to pack and transport the entire jungle gym of the present invention and its accessory slide (35), stairs (36), and top plate (37) into a flat rectangular parallelepiped, It is possible to store and store in a compact closet such as a veranda in a condominium.

  First, after folding the front and rear ground leg frames (F) and (R), the upper cube frame (C) and the lower middle cube frame (A) are folded, and the lower left and right cube frames (B1) ( Although B2) has been described as being folded, the operation order can be reversed, and the user can select it appropriately. Needless to say, if the operation sequence from the expanded use state to the folded state is performed in the reverse direction, the folded state can be restored and converted to the expanded use state.

  1 to 69, the front grounding leg frame (F) from the front to the lower left cubic frame (B1) and the rear grounding leg frame (R) from the rear to the lower right cubic frame (B2), respectively. Although it is pivotally attached, the rear ground leg frame (R) is pivotally attached to the lower left cube frame (B1), and the front ground leg frame (F) is pivotally attached to the lower right cube frame (B2) from the front. Furthermore, as shown in the modified embodiment of FIG. 70, the front and rear grounding leg frames (F) and (R) are pivotally attached to the lower central cube frame (A) from the front and rear, respectively, in the same manner as described above. It's okay.

  In this modified embodiment, as is clear from FIG. 71 corresponding to FIG. 68, the front and rear grounding leg frames (F) (R) folded first are the lower center cube frame (A) and the lower left side which are folded thereafter. -The result is that the right cube frame (B1) (B2) is sandwiched and constrained between the front and rear sides facing each other, and a stable folded flat state is obtained without the risk of inadvertent lowering or unfolding.

  And, such an effect is contrary to the illustrated embodiment, the rear grounding leg frame (R) from the rear to the lower left cubic frame (B1) and the front grounding leg frame from the front to the lower right cubic frame (B2). The same can be achieved when (F) is pivotally attached. In any case, the jungle gym of the present invention can be folded without any trouble by the above-described operation, and the conversion operation with the expanded use state can be performed.

  Furthermore, the jungle gym of the basic embodiment shown in FIGS. 1 to 69 includes a lower central cube frame (A), lower left and right cubic frames (B1) and (B2) juxtaposed on both sides thereof, and a lower central cube frame (A ) And the upper cubic frame (C) to be stacked, the three-dimensional framework is formed into an overall convex contour shape in a front view. However, in the vertical position relationship of the jungle gym, the cubic frame (A) (C Vertical bone pipes (Z) forming the vertical leg pipes (6Z) (16Z) of the first to fourth fixed pipe joints (J1) (J2) (J3) (J4) which are press-fitted and integrated therewith. 26Z), it will be unified.

  Therefore, for example, two or more jungle gyms in which the uppermost cube frame (C1) is further stacked on the upper cube frame (C) as shown by the chain line in FIG. 28, or the lower left / right cube frames (B1) (B2) 67-69 by performing exactly the same folding operation as in the above basic embodiment, even in the case of two or more jungle gyms in which the upper cubic frame (C2) is further laminated in parallel with either or both of the above. Can be obtained as a whole in a small and flat folding state, and belongs to the category of the present invention.
