In summary, according to the present invention, since the opening hatch 3 having the upper and lower openings is provided on the floor surface 1 and the door 17 which can open and close the upper opening 16 of the opening hatch 3 is provided, the swing of the door 17 is provided. The upper opening 16 of the opening hatch 3 can be opened by dynamic opening and closing, and the door 17 is not arranged at another position. Opening can be performed easily.

Also, the rail 10 is placed under the floor 2 or on the slab FL.
In addition to the provision of 10a, the movable box 4 having an upper opening is movably provided on the rails 10 and 10a. Therefore, the movable box 4 which is movable below the opening hatch 3 when the door 17 is opened is arranged. Since the moving box 4 can be used depending on the type, shape, size, etc. of the article, and the moving box 4 can be made larger than the opening hatch 3, the storage capacity can be increased, Also, since the positions of the lower opening 14 of the opening hatch 3 and the upper opening 15 of the moving box 4 can be freely matched, after the door body 17 is opened, the moving box 4 is moved to match the position of the opening hatch 3. Thus, articles can be stored in or removed from the moving box 4.

Further, two rows of bundle jacks 18, 18a... Are arranged between the floor plate 6 and the slab FL.
Since the pair of rails 10 and 10a are installed at the intermediate portion between the floor plate 6 and the slab FL at 18a..., The traveling sound generated when the moving box 4 moves on the rails 10 and 10a is generated by the rails 10 and 10a.
And the slab FL are not in direct contact with each other, so that they are not transmitted to the slab FL. Therefore, even if the underfloor storage 5 is installed in a room on the second floor or higher, there is no or reduced traveling sound transmitted to the downstairs. Can be done.

Further, since a part of the pair of rails 10 and 10a is supported by the walls 8 and 8a of the opening hatch 3, the arrangement positions of the rails 10 and 10a with respect to the opening hatch 3 can be ensured. Therefore, it is possible to improve the positional matching between the lower opening 14 of the opening hatch 3 and the upper opening 15 of the moving box 4, thereby facilitating the storage and removal of articles.
By supporting the rails 10 and 10a other than 8, 18a..., The erected state of the rails 10 and 10a can be improved.

The length L2 of the moving box 4 in the moving direction
Is set to be longer than the length L1 of the opening hatch 3, so that the area of the moving box 4 is made larger than that of the opening hatch 3 so that the storage capacity can be increased.
Since the length L3 in one direction is set to be longer than the length L2 of the moving box 4, the moving box 4 can be set to an exclusion state other than the position immediately below the opening hatch 3, and the moving box 4 can be set to a non-existent position The entrance to the underfloor 2 can be set with the simplicity of maintenance, and the lower opening of the opening hatch 3
Since the movable box 4 can be fixed to the opening hatch 3 when the position of the upper surface opening 15 of the movable box 4 matches the position of the movable box 4,
The movable movable box 4 is fixed directly below the opening hatch 3 so that the movable box 4 can be easily stored and removed from the movable box 4.

Further, in the fixing mechanism of the opening hatch 3 and the moving box 4, the fixing plates 104 and 104a projecting below the opening hatch 3 are arranged in the moving box 4, so that the moving of the moving box 4 is fixed. Due to the presence of 104 and 104a, the movement is limited to the position including the position directly below the opening hatch 3, the moving box 4 can be used without being removed, and the fixing plate can be improved.
Since 104 and 104a can be attached freely, the fixing plate 10
4 and 104a, the moving box 4 can be retracted from a position immediately below the opening hatch 3. Also, fixing holes 103 and 103a are formed in the fixing plates 104 and 104a of the opening hatch 3 and the walls 11 and 11a of the moving box 4. , 105 are provided, and the fixing pin 107 is freely inserted into the fixing holes 103, 103a,..., 105. Can be fixed to

Also, fixing holes 103 provided in the fixing plates 104, 104a of the opening hatch 3 and the walls 11, 11a of the moving box 4, respectively.
, 103a..., 105 have different shapes and the opening hatch 3
Since the fixing holes 105 provided in the fixing plates 104 and 104a are enlarged, the two fixing holes 103, 103a and 105 in the stacked state can be easily confirmed from the insertion operation side of the fixing pin 107.

The fixing holes 103, 103a,.
And the fixing hole 105 of the opening hatch 3 is formed as a U-shaped groove from below. Therefore, depending on the assembly work of the moving box 4 and the rails 10 and 10a under the floor 2, the vertical difference of the moving box 4 Even if the occurrence occurs, the two fixing holes 103
, 103a, and 105 can be matched in the vertical direction.

Further, since the door 17 is supported by the support mechanism 50 attached to the opening hatch 3 so as to be openable and closable, the upper opening 16 of the opening hatch 3 can be opened without moving the door 17 to another position. The support mechanism 50 is provided with first and second substrates 52 and 53 on the walls 9 and 9a and the door 17 of the opening hatch 3, respectively, and a first and second link 56 between the first and second substrates 52 and 53. And the first and second links 56 and 57 so that the first substrate 52 of the opening hatch 3 and the second substrate 53 of the door body 17 are substantially perpendicular to each other when the first and second links 56 and 57 are extended. , The opening position of the door body 17 with respect to the opening hatch 3 can be substantially vertical, that is, the entire opening state in which no obstruction exists above the upper opening 16 of the opening hatch 3 can be achieved. The storage and handling operation of the storage 5 can be facilitated.
Because the upper pivot point 57b of the second link 57 is not on the opening side with respect to the upper pivot point 56b of the first link 56 in the mounted state of the links 56, 57, or a part of the second link 57 is bent. However, the door 17 does not suddenly close in a natural state, and safety can be ensured.

Further, since the pressing body 51 for pressing the door 17 to the open swing side is provided near the first substrate 52 provided on the opening hatch 3 and the second substrate 53 provided on the door 17, the door is provided. When the door 17 is lifted upward during the swing release of the body 17, the pressing body 51 acts in the same direction, so that the opening operation force of the door 17 can be reduced, and It is also possible to prevent the door body 17 that is in the upright state from tilting and closing.

The door 17 is supported by a support mechanism 50 attached to the opening hatch 3 so as to be openable and closable, so that the door 17 can be erected at right angles to the opening hatch 3 and the door 17. Pressing body 51
The support mechanism 50 that can support the door 17 at right angles
The right angle state can be maintained by the pressing body 51 of any kind.

Since the corners 26, 26a, 31, 31a, etc. of the opening hatch 3 and the moving box 4 are R-shaped,
The practical effect is extremely large, for example, the safety at the time of using the underfloor storage 5 can be improved.
