A plurality of cover connection means (72-1,..., 72-n) (74-1) are movable along each rail by the length of the rail, and are installed so as not to escape from the rail groove of the rail. ..,74-n),

It covers the rectangular upper surface of the rectangular wall 10 on the sand, and the vertical surfaces on both sides are inserted into the rail grooves 520 and 540 of the opposing rails 52 and 54 and are movably connected to a plurality of cover connection means 72- 1,...,72-n) (74-1,...,74-n) is fixed to the cover connecting means (72-1,...,72-n) (74-1,... .,74-n), and a sand cover (20) moved together, and

Rotating axes (42, 44) located in parallel and located below the pair of opposing horizontal and vertical supports (13, 14) of the rectangular wall (10),

Insert into each hole 22 of the sand cover 20 to which the plurality of cover connecting means (72-1,...,72-n) (74-1,...,74-n) are connected. The wire is installed and passes through the sand cover 20 alternately in the upper and lower parts as if sewing, and is wound or unwound at two positions on the rotating axes 42 and 44 according to the rotation of the rotating axes 42 and 44 ( 82), and

It is characterized by including a power transmission means for transmitting rotational force to the rotation shafts 42 and 44.

In Figure 1, the sand cover 20 is opened and closed in one direction, but the side that does not move during the opening and closing operations can be fixed to a side vertical support or other vertical support.

The wire 82 is connected to each other in two places between the rotation axes 42 and 44 located in parallel positions, and the rotation shaft 44 is also rotated in conjunction with the rotation of the rotation shaft 42, and the wire 82 is It is wound around the rotation shaft 42 or around the rotation shaft 44.

The back of the cover connection means (72-1,...,72-n) (74-1,...,74-n) is approximately cylindrical, and the rear surface is faced with the inside of the rail groove (520) (540), It has a substantially cylindrical body (72-1) with a portion of the front of the body exposed outside the rail grooves (520) and (540), and rotatable wheels (722,724) are provided on the upper and lower sides of the cylindrical body (72-1). is rotatably installed, and front bending portions 728 and 729 are formed on the upper and lower surfaces of the rail grooves 520 and 540 so as to be rotatably positioned on the inner upper surfaces of the rail grooves 520 and 540 to prevent external separation. A ring portion 726 is protruding from the front center of the cylindrical body 72-1, and the ring portion 726 is fixed to the hole 22 of the cover 20 like a ring. The cover connecting means (72-1,...,72-n) (74-1,...,74-n) may all be collectively referred to as reference numeral 70.

In the sand storage box cover opening and closing device for sand play constructed as described above, the sand cover 20 covers the sand 60 in normal times, as shown in FIG. 1.

When playing with sand, rotate the handle 32 of the rotating means 30 to rotate the rotating shaft 42 fixed to the center of the rotating plate 33, and open the sand cover 20 by rotating the wire 82. (see Figure 2).

The handle 32 is for transmitting rotational force to the wire 82, and it is of course possible to apply rotational force through the on/off switch using a method using power such as a motor (not shown). will be.

Referring to FIG. 3, when the handle 32 is rotated in one direction, the rotating shaft 42 rotates, and the wire 82 wound around the rotating shaft 42 begins to wind at two positions on the rotating shaft 42, At the same time, the wire 82 is moved by interviewing the holes 22 of the sand cover 20 in a straight line along the upper and lower surfaces of the sand cover 20, as if quilting the sand cover 20, and the wire 82 is moved along the upper and lower surfaces of the sand cover 20.

Meanwhile, among the cover connecting means (72-1,...,72-n) (74-1,...,74-n), the cover connecting means (72-1,..., 72-n)(74-1,...,74-n) are fixed to the wire 82. This serves as the end point of the rotational force through the initial handle 32, so that the wire 82 can continue to be pulled little by little in one direction and can be controlled so that it is not released any further in the other direction.

Referring to Figure 4, the part where the sand 60 is installed is the rail 52 on which the cover connecting means (72-1,...,72-n) (74-1,...,74-n) are installed. , 54) is located below the part, and the sand 60 cannot penetrate. The sand cover 20 is integrated into the cover connection means 72-1,...,72-n) (74-1,...,74-n) and the wire 82 through the hole 22. It is connected, and the wire 82 is tensioned to maintain elasticity so that the middle part of the sand cover 20 does not sag toward the upper surface of the sand 60. The upper surfaces of the upper edges of the rails 52 and 54 are wide so that children can sit on them or move while playing in the sand.

Referring to Figure 6, when the sand cover 20 is unfolded (sand closed), the fold line 23 is visible as shown in Figure 1, and when the sand cover 20 is folded to one side, it is shown in Figures 2 and 2. As shown in 5, the sand cover 20 is tilted to one side as it is folded around the fold line 23 (opening the sand).
