It relates to a jungle gym with an open panel closed selectively by installing panels on the side.

In general, jungle gym is a recreational facility that is installed in a park or a playground for children to play, and is installed in the form of a three-dimensional grid so that children can climb, descend, cross, climb, sit and play.

In the case of the traditional jungle gym, the metal rods are stacked in the shape of a square grid, and the joints are fixed by welding. However, these jungle gyms have to be welded and fixed at the joints, which requires a lot of work time. Safety risks were inherent, such as falling children playing.

As a conventional technology for solving this problem, Korean Utility Model Registration No. 20-0225156 (Patent Document 1) constructs a jungle gym by interconnecting unit rods of the same size so that they can be easily installed by simple assembly rather than welding. However, to form a flat portion at both ends of the unit rod, form a long hole in the center of the flat portion, and the holes in the center of the flat portion of these unit bars to coincide with each other to start the jungle load fastened with bolts and nuts

In addition, domestic utility model registration No. 20-0206153 (Patent Document 2) is connected to each metal frame and frame made of jungle load by welding work, so it takes a lot of welding work time, so each frame and frame is easily bolted Hemi-assembled hemispherical jungle gym, which allows you to easily assemble jungle gym in a short time with a small number of workers.

However, the jungle gym such as Patent Document 1 and Patent Document 2 is improved only in the connection form, the play method is no difference from the traditional jungle gym. In other words, when children play in the jungle gym, they are not only limited to amusement because of the monotony that they have to go up and down or move by holding their bars or stepping on their feet. There is this.

Accordingly, the present invention was devised to solve the problems of the conventional jungle gym, and its object is to have various forms of the open surface formed by the bar forming the skeleton in the jungle gym, and also a part of the open surface formed by the bar By closing it, it is possible to double the amusement, but also to use as a scaffolding or to minimize the impact when falling to improve the safety as well as to provide a jungle load connection structure that can be easily and quickly assembled.

When the 43 is pushed down and the rail 43 and the slit groove 31 are coupled while sliding, the bracket 40 is fixed without being separated from the joint ring 30.

Next, as shown in FIGS. 4 and 5, when the other joint ring 30, that is, the joint ring 30, which is not fixed to the bracket 40, is pushed in the direction of the connector 10, the rail of the bracket 40 is inserted. The slit groove 31 of the joint ring 30 is fitted into the 43, and is also slide-bonded to be in the state of FIG. 5.

As described above, since the rails 43 and the slit grooves 31 are each trapezoidal in cross section, the two joint rings 30 fixed to one bracket 40 are each without a fastening means such as a separate screw. It will remain fixed to each other.

Although not shown here, the cross-sectional shape of the slit groove 31 and the rail 43 is not limited to a trapezoidal shape to be assembled in a slide manner. That is, when each cross-sectional shape of the slit groove 31 and the rail 43 is made into a triangle or a quadrangle, the two adjacent joint rings 30 are fixed to contact the connector 10 side, and then each joint ring ( It will be appreciated that the rail of the bracket 40 can be fitted in a direction perpendicular to the slit groove 31 of 30.

Figure 8 is an exploded perspective view of the main portion showing another embodiment of the jungle load connection structure according to the present invention, Figure 9 is a perspective view showing the assembled state of the jungle load connection structure of Figure 8, each vertex portion of the hexagonal panel 60 A bracket 40 for securing to the connector 10 is disclosed.

The bracket 40 for fixing the hexagonal panel 60 differs only in that the angle formed by the two ring engagement surfaces 41 is deformed to 120 ° as compared to that for fixing the hexagonal panel as described above. Only the remaining components and their associations are the same. Of course, in order for the hexagonal panel fixing bracket 40 to be coupled to the joint ring 30, the first fastening means 11 of the connector 10 is maintained at an angle of 120 ° so that two bars 20 corresponding thereto are formed. This rune angle must be maintained at 120 °.

Through this coupling relationship, according to the installation position (angle) of the first fastening means 11 of the connector 10, the bar 20 can form an open surface of a quadrangular or hexagonal shape as illustrated. Of course, it is possible to achieve a triangular, five-or eight-octagonal form. Furthermore, when the bracket 40 and the panel 60 corresponding thereto are provided, the jungle gym can be assembled to form an open surface of the polygon, and when the polygonal panel is provided correspondingly, any open surface can be selectively closed. I can understand that.

FIG. 10 is an exploded perspective view illustrating a bracket form for fixing a hexagonal panel as illustrated in FIG. 8.

As shown in FIG. 8, the hexagonal panel fixing bracket 40 includes two first brackets 40a and a second in which a support surface 42 is cut out so that two adjacent ring engagement surfaces 41 are separated from each other. It is made of a bracket (40b), the upper support surface (42a) is formed to extend on one side support surface so that the cut support surface 42 is overlapped with each other, the lower support surface (42b) is formed to extend on the other support surface It is preferable.

At this time, the first bracket hole 44a and the second bracket hole 44b are disposed at the same position so that the second fastening means 70 can be fastened to the upper support surface 42a and the lower support surface 42b, respectively. Is installed.

The reason why the hexagonal panel fixing bracket 40 is separated into the first bracket 40a and the second bracket 40b is as follows.

As shown in Figure 2, when installing a jungle gym mixed with a four-sided panel and a hexagonal panel, first form a jungle gym skeleton of the shape as shown in Figure 2 through the connector 10 and the bar 20, then 4 A quadrilateral panel is installed in the selected position of each open surface by the process of FIGS. 4-7.

In this case, since the joint ring 30 is fixed to the quadrilateral panel, when the hexagonal panel bracket is not separated, both ring coupling surfaces 41 may not be installed on the two joint rings 30.

Therefore, after designing the hexagonal panel bracket separately as shown in FIG. When the first bracket 40a and the second bracket 40b are coupled to each other, the upper support surface 42a and the lower support surface 42b overlap so that the second fastening means 70 can be fastened. do.

11 is a partial cross-sectional view showing another embodiment of the jungle gym connection structure according to the present invention, showing a fixing structure of the joint ring (30).

As shown in FIGS. 2, 3, and 11, the plurality of bars 20 are connected to one connector 10 through a structure in which the first fastening means 11 of the connector 10 is screwed to the bar hole 21. The joint ring 30 is fixed to the outer surface of the bar 20, and the bracket 40 fixing the panel 60 is fixed to the two joint rings 30 as described above.

At this time, some of the open surface of the jungle gym as shown in Figure 2 does not install the panel 60 so that children pass through, the panel 20 is not in contact with the open surface bar 20 is not installed bracket 30 It is not necessary to install, and it is necessary to fix the joint ring 30 of the part in which the bracket 30 is not installed to the both ends of the bar 20.

That is, when the joint ring 30 is not fixed to the bar 20 and moves on its outer surface (see FIG. 4), the joint ring 30 is movable on the outer surface of the bar 20 while children play. You may be at risk of a safety accident.

Therefore, it is preferable to form a stopper 32 extending at the end of the joint ring 30 to be in contact with the tip surface of the bar 20. As an example, as shown in FIG. 11, a stopper 32 extending in the center may be installed so that the inner diameter of the end portion of the joint ring 30 toward the connector 10 is smaller than the diameter of the bar 20, and the stopper ( 32 may be manufactured by integrally molding the joint ring 30. In this case, the stopper 32 is interposed between the connector 10 and the tip of the bar 20 so that the joint ring 30 is fixed without sliding the outer surface of the bar 20.

Accordingly, when constructing a jungle gym as illustrated in FIG. 1, the joint ring 30 having the stopper 32 is installed on the bar 20 of the open surface on which the panel 60 is not installed, and the panel 60 is provided. ) May be provided with a joint ring 30 is not provided with a stopper (32).

Of course, in order to reduce manufacturing costs through the use of parts, it is preferable to use only one joint ring 30 having a stopper 32 as shown in FIG. 11, in which case, the brackets 40 are provided on two adjacent joint rings 30. Since the slit groove 31 and the rail 43 cannot be assembled in a sliding manner when fastening), the cross-sectional shape of each of the rails 41 of the slit groove 31 and the rail 41 is not a trapezoidal shape but a triangular or square shape. Or semicircular.

While the above has been shown and described with respect to preferred embodiments of the present invention, the present invention is not limited to the specific embodiments described above, it is usually in the technical field to which the invention belongs without departing from the spirit of the invention claimed in the claims. Various modifications can be made by those skilled in the art, and these modifications should not be individually understood from the technical spirit or the prospect of the present invention.
