Description

[Detailed description of the device]

[0001]

[Industrial application] The present invention relates to a simple room to be placed in a child's facility such as a kindergarten or a facility for displaying various products, and particularly to a lid having a spherical portion (hereinafter referred to as a dome).
Of the simple room opening and closing door.

[0002]

2. Description of the Related Art The applicant of the present application has developed and implemented a dome-shaped simple room for a kindergarten. The opening / closing door device in the spherical portion of the prior example by the applicant of the present application is shown in FIG.
This shows that the entrance / exit 4 is formed in the spherical surface portion 2 of the room main body, and the U-shaped rail 12 is attached to the spherical surface portion 2 via the ridge 25 provided along the spherical surface portion 2. A U-shaped rail 13 parallel to the U-shaped rail 12 is attached to the lower side of the wheel, and a wheel 14 that rotates vertically is attached to the upper end of the spherical strip-shaped door 9, and the wheel 14 is inserted into the U-shaped rail 12. Put it on the rail bottom 15 and hang the door 9,
A roller 16 that rotates in the horizontal direction is attached to the lower end of the door 9, and the roller 16 is put in the U-shaped rail 13 in a floating state.

[0007]

As shown in FIGS. 1, 2, and 5, the spherical portion 2 which is a component of the room main body 1 has a spherical crown portion 17 supported by left and right spherical band piece walls 18, 18. . Here, the portion of the spherical crown portion 17 located above the doorway 4 is not supported from below. Therefore, in the case of the prior art example in which the door 9 is a hanging door type, the weight of the door 9 is the U-shaped rail 12 and the shed 25.
Spherical portion 2 that covers the spherical crown portion 17 through
May be deformed or damaged.

Further, as described above, in the prior art, the door 9 is supported by the shed 25 and the turning radius of the wheel 14 is smaller than that of the roller 16 (difference between r1 and r2 in FIG. 5).
Since a large force is applied to the door 9 and the door 9 is easily shaken, and as shown in FIG. 6, the door 9 in the preceding example has a spherical strip shape and is inclined inward, the lower end of the door 9 moves in the direction of the dotted arrow. The roller 16 is strongly pressed against the inner wall surface 19 of the U-shaped rail 13 during the movement, and it is difficult to open and close the door 9 smoothly, and thus an extremely large force is required when opening and closing. In the preceding example, many scratch marks could be visually recognized on the wall surface 19 inside the U-shaped rail 13.

[0009]

According to the present invention, a room main body 1 is formed by connecting an end room segment composed of a spherical surface part 2 having a quarter spherical shape to an end part of a semicircular intermediate room segment 20. , The entrance / exit 4 is formed at the spherical zone position 3 of the spherical surface portion 2, the U-shaped rail 6 is attached along the spherical zone upper edge 5 of the spherical surface portion 2, and the ground rail along the spherical zone lower edge 7 of the spherical surface portion 2. 8 is attached, a roller 10 that rotates about a vertical axis is attached to the upper end of a spherical strip 9 that opens and closes the doorway 4, and a door roller 11 that rotates about a horizontal axis is attached to the lower end of the door 9. The roller 10 is arranged in the U-shaped rail 6, and the door roller 1
1 is mounted on the ground rail 8.

Each spherical portion 2 has a spherical crown portion 17, left and right spherical strip piece walls 18, 18, and doors 9, 9 for opening and closing an entrance 4 formed between the left and right spherical strip piece walls 18, 18. And consists of.
Specifically, the entrance / exit 4 is formed in the spherical zone position 3, that is, a spherical surface portion between two parallel cut surfaces, and the spherical zone portions on the left and right of the entrance / exit 4 are formed by the spherical zone piece walls 18, 18. More specifically, a yard 23 is provided along the upper end of each bulb strip wall 18,
An outward flange 24 is provided along the lower end, and a shed 25 is provided along the lower end of the spherical crown portion 17, so that the longitudinal length of the shed 25 is inward of the lower end of the spherical crown portion 17 and faces the entrance 4. Piece 2
The covering piece 27 parallel to 6 is fixed. Then, the sphere band piece walls 18, 18 having the skirt 23 provided along the upper end thereof are connected to the spherical crown portion 17 having the hood 25 provided around the lower end thereof.

A U-shaped rail 6 is attached along the upper edge 5 of the spherical zone. Specifically, as shown in FIGS. 3 and 4, the slab 25 facing the doorway 4 does not have a slab 23, so the wall thickness l of the slab 23
Attach a spacer 28 of the same thickness as the bottom of the skirt 25,
The U-shaped rail 6 is attached to the spacer 28 (in the case of FIG. 3) and the lower surface of the mound 23 (in the case of FIG. 4). Also the lower edge of the sphere 7
A rail cover 29 is provided along the circumference. As shown in FIG. 3, the rail cover 29 has front and rear ridges 30 and 31, a concave portion 32 and a flat grounding portion 33 between the front and rear ridges 30 and 31, and extends along the left and right spherical band piece walls 18 and 18. As shown in FIG. 4, the location has a front ridge 34 and a flat portion 35, and the lower end of the ridge 34 and the flat portion 35 are placed on the outward flange 24. The height of the ridge 30 is longer than that of the ridge 34 by the thickness h of the outward flange 24. And the lower edge of the sphere 7
