FIG. 6 is a schematic perspective view showing a state in which the slide is extended, and FIG. 7 is a perspective view of an assembly part of the assembly type jungle gym 11.

In this embodiment, the upper and lower ends of the jungle gym 11 for infants assembled as shown in FIG. 6 and FIG. Shows a slide. The assembled jungle gym 11 has a large number of joints 15 and lateral pipes 12 as shown in FIG. The joint 15 is generally made of a plastic injection-molded body, has a tube portion in the longitudinal direction, and has projecting portions 16 integrally formed on the outer periphery of the joint portion in two or three mutually orthogonal directions. . As an example, the protruding portion 16 is formed in a cross shape in cross section, and the end portion of the horizontal pipe 12 is press-fitted therein. As an example, the lateral pipe 12 is made of a paper pipe, the surface of which is coated with a synthetic resin film. Similarly, the vertical pipe 13 shown in FIG. 6 is also made of a paper pipe and is formed by winding a large number of papers into a tubular shape. The end of the horizontal pipe 12 or the vertical pipe 13 is press-fitted into the protrusion 16 or the opening of the short pipe to assemble the assembly type jungle gym 11 shown in FIG. An inner flange (not shown) is formed in the center of the inner surface of the pipe portion of the joint 15, and the tip of the vertical pipe 13 abuts on it.

A second slope 7, a first slope 5 and a landing board 1 are connected to the assembly type jungle gym 11 thus configured as shown in FIG. 1 or 6. As shown in FIGS. 1 and 6, the landing plate 1 is detachably fitted to the lateral pipe 12 of the assembled jungle gym 11, and is formed as shown in FIG. That is, it is made of a synthetic resin body formed by injection molding or blow molding with a plate thickness of about 3 to 6 mm, and is formed into a flat rectangular shape, and groove-like pipe fitting portions 14 are formed on both lower surfaces in the longitudinal direction thereof. At the same time, a groove-shaped pipe fitting portion 14 opening upward is formed at one end in the width direction. Then, the pipe fitting portions 14 on both sides of the landing plate 1 are fitted to a pair of horizontal pipes 12b (one of which is hidden in the drawing) facing each other as shown in FIG. The pipe fitting portion 14 on the back side of the plate 1 is fitted. The fitting direction on both sides and the fitting direction on the back side are opposite to each other, whereby the landing plate 1 is attached so as not to come off in any direction. The upper surface of the landing board 1 is formed in a plate shape that is trimmed except for the slide side, and a non-slip pattern (not shown) is projected on the bottom surface of the plate.

Next, the first slope 5 adjacent to the landing board 1 is provided with a short horizontal entrance portion 9 at the upper end thereof, and subsequently, a sliding surface 4 having a thickness of about 3 to 6 mm is formed in the longitudinal direction. It The side rails 3 are integrally formed on both sides of them. In this embodiment, the first slope 5 and the second slope 7 to be described later are injection molded or blow molded products of synthetic resin. The sliding surface 4 and the side rail 3 of the first slope 5 are bent in a V shape, and a pipe fitting portion 14 is formed on the lower surface of the upper end portion, that is, the lower surface of the inlet portion 9. The pipe fitting portion 14 is formed in a shape that matches the horizontal pipe 12a of the assembled jungle gym 11, similar to the pipe fitting portion 14 of the landing board 1. Further, the pipe fitting portion 14 is formed in a U-shaped groove shape on the lower surface of the upper end portion of the first slope 5 as shown in FIG. 2, and a concave portion is formed at a corner portion thereof so as to avoid the joint 15. . Then, only the pipe fitting portion 14 on the closed side of the U-shaped groove is supported by the lateral pipe 12a of the assembled jungle gym 11.

Next, the cross section of the first slope 5 is composed of a plate portion having a thickness of 3 to 6 mm which is bent in a concave shape as shown in FIG. 3 except for the pipe fitting portion 14. The sliding surface 4 forming the central flat surface and the side rails 3 located on both sides of the sliding surface 4 are integrally formed with a smooth curve. In addition, reverse U-shaped concave portions are formed on the back surfaces of the side rails 3 on both sides of the first slope 5 so as to be aligned with the pair of circular convex portions 10 protruding on both sides of the second slope 7. . Next, the cross section of the second slope 7 has a box shape in which, in this embodiment, the upper surface thereof is formed into a concave portion which is aligned with the lower surface of the sliding surface 4 of the first slope 5 as shown in FIG. The upper surface is composed of a sliding surface 4a and a pair of side rails 3a located on both sides of the sliding surface 4a, and a pair of circular convex portions 10 spaced apart from each other in the longitudinal direction are formed integrally at two outer sides of the side rail 3a. Has been formed. Further, as shown in FIG. 6, the second slope 7 is provided with an outlet 8 having almost no inclination at the lower end thereof. Further, on the lower surface of the upper end of the second slope 7, as shown in FIG. 1, a recess for fitting the leg 6 is formed. That is, as shown in FIGS. 1 and 5, the upper end portion of the leg portion 6 is formed with a stepped ridge 17 extending in the width direction of the second slope 7, and a concave portion aligned with the stepped ridge 17 has a concave portion. 7 is formed on the lower surface of the upper end portion.

Next, as shown in FIGS. 1 and 5, the leg portion 6 has a side surface formed into an inverted U-shaped tubular shape, and its opening portion is integrally connected by a plate-shaped member. In addition, the upper end surface and the lower end surface form an inverted V-shaped inclined surface. Then, the stepped ridge 17 described above is formed at the end of the upper end surface. The tip of the stepped ridge 17 is formed in a round bar shape. The leg portion 6 is made of a synthetic resin blow molded product or an injection molded product. Next, how to use this slide will be described. First, the assembly type jungle gym 11 is assembled, and the landing board 1 is fitted and placed on the lowermost step of the outer peripheral portion. Then, the lower surface of the upper end of the second slope 7 and the upper end of the leg 6 are fitted to each other. Next, the pipe fitting portion 14 on the lower surface of the upper end of the first slope 5 is fitted to the horizontal pipe 12a. Then, the lower surface of the first slope 5 is placed on the second slope 7, and the circular convex portion 10 is supported so as to be aligned with the concave portion of the side rail 3 of the first slope 5. By doing so, the infant can use the assembled jungle gym 11 to ride on the first landing board 1 and slide down from the first slope 5 to the second slope 7. It has been confirmed by experiments that there is a step difference of about 3 to 6 mm at the downstream end of the first slope 5, but there is no problem in practical use. In other words, it was found that such a level difference does not feel strange.

Next, the landing board 1 is fitted onto the second step as shown by the chain line in FIG. 1, as shown in FIG. 6, and the upper end of the first slope 5 is fitted to the horizontal pipe 12a adjacent to the landing board 1. . Then, the concave portions formed on the rear surface of the side rail 3 of the first slope 5 are fitted into the circular convex portions 10 arranged on both sides of the upper end of the second slope 7. By doing so, it becomes possible to form a slide having a long overall length as shown in FIG. 6 and to slide down from a higher position. Further, since this slide uses the assembled jungle gym 11, it does not fall even if a force is applied from the side of the slide. This is because the assembly type jungle gym 11 itself is stable with respect to external force from the side, because the entire plane thereof is assembled so as to extend in a cross shape or the like on the plane.
