DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connection structure for a slide underfloor storage.

[0002]

2. Description of the Related Art Conventionally, when a plurality of slide underfloor storages are suspended and supported between two rails attached to a floor opening, the slide underfloor storages are not connected to each other. The underfloor storage moves independently, but the moving operation takes time. Therefore, as another conventional example, for example, Japanese Utility Model Application Laid-Open No. 58-39934 discloses a method of connecting slide underfloor storages using a connector. A connecting structure is disclosed.

[0003]

However, the connecting device of this conventional example is formed in the shape of a pin which is bridged between the upper surfaces of the corners of the adjacent slide underfloor storages. It is easy for displacement to occur in the direction orthogonal to the direction of movement between the two, and in this case, there is a possibility that the connecting tool may be deformed or damaged by a twisting force, and the connecting strength between the slide underfloor storages. However, there was a problem that was reduced. In addition, since both ends of the pin-shaped connecting tool are fixed to each upper surface of the adjacent slide-floor storage using a tool such as a hammer, the connecting work is time-consuming, and the connecting tool is difficult to remove, and the slide-floor floor can be removed. There was also a problem that the detaching work was troublesome when cleaning the storage.

The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to enable a plurality of slide underfloor storages to be easily and reliably connected to each other without tools at the time of construction. An object of the present invention is to provide a connection structure of a slide underfloor storage that can easily perform a work of separating the slide underfloor storage.

[0005]

In order to solve the above-mentioned problems, according to the present invention, a plurality of sliding underfloor storages 3 are suspended and supported between two rails 2 attached to a floor opening A, respectively. The adjacent slide-under-floor storages 3 are connected to each other by a connection fitting 4, and the connection fitting 4 is connected to a side-surface contact piece 4 b that abuts each corner side surface 6 b of the adjacent slide-under-floor storage 3. Notches 8 formed on the upper surface 6a of each corner of the adjacent slide underfloor storage 3, respectively.
And a pair of insertion pieces 4c individually inserted from above.

Further, it is preferable that the lower end 4e of the side contact piece 4b hang down below the lower end 4f of the insertion piece 4c.

[0007]

According to the present invention, an adjacent slide underfloor storage 3 is provided.
Metal fittings 4 are formed on the side surface contact pieces 4b abutting along the respective corner side surfaces 6b of the adjacent slide underfloor storage 3 and the respective corner upper surfaces 6a of the adjacent slide underfloor storage 3 respectively. Is formed from the pair of insertion pieces 4c individually inserted from above into the cutouts 8 formed, so that the connection metal fitting 4 is made up of the side contact piece 4b and the insertion piece 4c.
With c, the cross-sectional shape becomes an inverted U-shape, the bending and breakage of the connecting fitting 4 are hardly generated, and the connecting fitting 4 is strengthened in strength. In addition, since the side contact piece 4b abuts on the corner side surface 6b of the slide underfloor storage 3, mutual displacement of the slide underfloor storage 3 in the direction C perpendicular to the moving direction B can be prevented, and a plurality of slides can be prevented. The side surface of the underfloor storage 3 can be held flush when viewed from above. Furthermore, the connecting bracket 4
Can be easily connected simply by inserting the respective insertion pieces 4c from above the respective notches 8 on the corner upper surface 6a of the adjacent slide underfloor storage 3.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. In the present embodiment, as shown in FIGS. 4 and 5, two rails 2 (one of which is not shown) mounted in parallel with the floor opening A have the same opening area as the floor opening A. In a structure in which a plurality of slide underfloor storages 3 are suspended and supported, a connection fitting 4 for connecting two adjacent slide underfloor storages 3 to each other is provided. In addition, the slide underfloor storage 3 includes a moving frame 6 with a roller 5 and a storage container 7 supported by the moving frame 6. In this embodiment, as shown in FIG. Notches 8 are formed on the upper surface 6a, and each notch 8 is formed in a long hole shape along the moving direction B of the moving frame 6.

On the other hand, as shown in FIG.
One thin plate is formed by bending, and has an upper piece 4a of a length spanning a corner upper surface 6a of an adjacent moving frame 6, and a side contact piece 4b is formed from one edge of the upper piece 4a. The upper piece 4a is bent at a right angle, and a pair of insertion pieces 4c are formed on both sides of the end edge of the upper piece 4a opposite to the side contact piece 4b in a direction parallel to the side contact piece 4b. It is bent. Here, in a state where the upper piece 4a of the connection fitting 4 is stretched along the corner upper surface 6a of the adjacent moving frame 6, the side abutment pieces 4b hang down along the corner side surfaces 6b of the adjacent moving frame 6, respectively. In addition, the pair of insertion pieces 4c are formed with notches 8 formed on the corner upper surfaces 6a of the adjacent moving frames 6, respectively.
Can be inserted from above. In this embodiment,
The lower end of the insertion piece 4c hangs down below the lower end of the side contact piece 4b, and after the insertion piece 4c is inserted into the notch 8, the side contact piece 4b becomes the corner side of the moving frame 6. The contact can be made along 6b. Also, between the insertion pieces 4c of the upper piece 4a of the connection fitting 4, the projecting piece 4 is horizontally flush with the upper piece 4a.
d is extended, and the overhanging piece 4d further improves the strength of the connection fitting 4 itself. Note that the overhanging piece 4d may be omitted.

A slot 8 is formed in advance on the upper surface 6a of the four corners of the moving frame 6 along the moving direction B of the moving frame 6, as shown in FIGS. 4 and 5. As described above, the two rails 2 with the moving frame 6 attached to the floor opening A,
The storage containers 7 are attached to the respective moving frames 6 while being suspended and supported between the two. Thereafter, as shown in FIG. 1, the adjacent moving frames 6 are brought into contact with each other, and the right corner and the left corner of each moving frame 6 are connected to two connecting brackets 4.
(One is not shown). At this time, each insertion piece 4c of the connection fitting 4 is connected to the corner upper surface 6 of the adjacent moving frame 6.
a into the two notches 8 facing each other from above, and thereafter, the side contacting pieces 4b of the connecting fitting 4 are brought into contact with the corner side faces 6b of the adjacent moving frame 6, respectively, thereby connecting the fittings. 4 completes the connection work between the moving frames 6.

The connecting member 4 has an inverted U-shaped cross section formed by the side contact member 4b and the insertion member 4c, so that the connecting member 4 is unlikely to be bent or damaged, and has a high strength. It is strong, and its strength is further enhanced by the overhanging piece 4d. Therefore, by abutting the side contact pieces 4b along the corner side surfaces 6b of the adjacent moving frames 6, the slides 3 are displaced from each other in the direction C orthogonal to the moving direction B of the storage unit 3 under the floor. Is prevented, the side surfaces of the plurality of slide underfloor storages 3 can be held flush when viewed from above, so that no twisting force is applied to each insertion piece 4c, and deformation, breakage, etc. can be reliably prevented. In addition, each of the insertion pieces 4c of the connection fitting 4 is connected to the adjacent slide underfloor storage 3
Can be easily connected simply by inserting from above the notches 8 on the corner upper surface 6a, so that a plurality of slide underfloor storages 3 can be easily and reliably connected to each other at the time of construction without tools, and the slide underfloor storages can be connected. There is an advantage that the connection strength of No. 3 can be maintained for a long time. On the other hand, the connecting fitting 4 can be easily removed from the slide underfloor storage 3, and when the slide underfloor storage 3 is cleaned, the work of separating them can also be easily performed.

In this embodiment, the adjacent moving frames 6 are connected by the two connecting fittings 4. However, the moving frames 6 may be connected by one connecting fitting 4. In this case, the connecting fitting 4 itself has high strength. Since it has a strong structure, a decrease in connection strength can be suppressed as much as possible. Further, as a modified example of the connection fitting 4 ', as shown in FIGS. 6 and 7, the lower end 4e of the side contact piece 4b may be made to hang down below the lower end 4f of the insertion piece 4c. . In this case, before inserting the insertion piece 4c of the connection fitting 4 'into the notch 8 on the moving frame 6 side, the side contact piece 4b is made to follow each corner side face 6b of the adjacent slide underfloor storage 3 respectively. The side contact piece 4b functions as a guide. Therefore, the insertion operation can be easily performed while aligning the insertion pieces 4c with the notches 8, respectively, and the slide underfloor storage 3 can be inserted.
Connection work becomes easier. Further, there is an advantage that the strength of the connecting fitting 4 'can be further increased by extending the side contact piece 4b below the insertion piece 4c.

In the above embodiment, the slide underfloor storage 3 is divided into the movable frame 6 with the roller 5 and the storage container 7, and the corners of the adjacent movable frame 6 are connected to the connecting fitting 4 (4 ').
However, the present invention is not limited to this, and the moving frame 6 with the roller 5 and the storage container 7 may be integrated with each other. In short, the notch 8 can be provided on the corner upper surface 6a, and the corner side surface 6b The shape and structure of the slide underfloor storage 3 are not limited as long as the side contact piece 4b of the connection fitting 4 can be brought into contact therewith.

[0014]

As described above, according to the present invention, a plurality of slide-under-floor storages are suspended and supported between two rails attached to the floor opening, and adjacent slide-under-floor storages are connected to each other by the connecting fitting. The connection fittings are connected to each other, and the connection fittings are provided on side contact pieces that contact each side of each corner of the adjacent slide underfloor storage, and cutouts respectively formed on the upper surfaces of the respective corners of the adjacent slide underfloor storage. On the other hand, the connecting bracket has a pair of insertion pieces that are individually inserted from above, so that the connecting bracket has an inverted U-shaped cross-sectional shape due to the side contact piece and the insertion piece, and the As we become stronger,
The side abutment pieces can prevent mutual displacement in a direction orthogonal to the moving direction of the slide underfloor storage, and as a result,
Multiple under-floor storages can be easily and securely connected to each other without tools at the time of construction, and the connecting bracket can be easily removed from the under-floor storage, making it easy to separate slide-under-floor storages. There is an effect that can be performed.

In the case where the lower end of the side abutment piece is hung below the lower end of the insertion piece, before the insertion piece of the connecting bracket is inserted into the notch on the moving frame side, the side abutment piece is not provided. By arranging the contact pieces along the sides of each corner of the adjacent slide underfloor storage, the side contact pieces function as guides, and the insert pieces can be easily aligned with the notches while positioning each piece. Insertion operation can be performed, and connection work of the slide underfloor storage can be performed more easily.
