The baskets that were put in were stored directly on the underside of the floor within reach.

[0003]

In this case, even if the hand can reach it, there is a problem that it takes time to put in and take out the stored items in the back. Moreover, there is a problem that a large amount of space cannot be stored because the space under the floor that is completely out of reach of the storage space cannot be utilized effectively.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide an underfloor storage device which can store a large number of items and requires a small storage port.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a floor surface portion with a stored article take-out port, and
Under the floor, an endless horizontal rail and a plurality of storage bases interlockingly connected in an endless manner and sequentially sent to the storage outlet along the horizontal rail were provided.

Further, the pair of connecting pieces are pivotally mounted about the vertical axis so as to be swingable and openable, and the side edges of the adjoining storage bases can be brought close to each other and the legs can be freely opened and closed. The swinging end portions of the above are fixed to the back portions of the adjacent storage bases, respectively.

Further, a reinforcing column is arranged in the space inside the endless horizontal rail closed in a ring shape, and the column supports the floor portion corresponding to the space. Also, in the space inside the endless horizontal rail closed in a ring,
A storage section different from the storage stand was provided, and a storage section outlet was provided on the floor surface section corresponding to the storage section.

The motor further includes a motor and a pair of pinion gears that rotate in the same direction by driving the motors and are arranged with an axial center gap larger than a lateral gap between adjacent storage bases, and the pinion gears are sequentially meshed with each other. A horizontal rack section was provided on the back of the storage table.

Further, there is provided a shaft with a manual handle, and a pair of pinion gears which are interlockedly rotated in the same direction by the rotation of the shaft and arranged with an axial center gap larger than a lateral gap between adjacent storage bases. A horizontal rack portion in which the pinion gears are sequentially meshed is provided on the back of the storage base.

Further, a back plate member is attached to the storage table, and a large number of slits in which the pinion gears are successively meshed are formed in the back plate member at equal pitches in the horizontal direction, and a rack portion is constituted by the plurality of slits.

Further, the storage base is provided with a main roller running along the horizontal rail and a sub roller arranged outside the main roller and supporting the storage base together with the main roller,
A plastic cover member having a horizontal running path on which the sub-roller rolls was provided on a horizontal base frame laid under the floor, and a horizontal rail was provided inside the horizontal running path.

Further, the horizontal rail has a pair of vertical guide surfaces near the center and a pair of horizontal weight supporting surfaces extending outward from the guide surfaces in its cross-sectional shape.

[0013]

[Operation] If one storage rack is moved, the other storage racks also run in line with it, and the storage rack rotates endlessly along the horizontal rails, making it easy to store the desired storage rack containing stored items. It can be sent to the storage outlet. Therefore,
Even stored items located in the back can be easily taken out, and the storage space is not limited by the size of the stored item outlet.

Further, since the adjacent storage bases are connected to each other at the back portion thereof by a pair of swingable openable / closable connecting pieces, it is possible to minimize the lateral gap between the adjacent storage bases. . Furthermore, since the horizontal rail has an endless shape that is closed in an annular shape, there will be an empty space inside the horizontal rail, but if columns are placed in this space to support the floor surface, Since the floor surface can be reinforced, the space under the floor can be utilized without waste. Alternatively, this space portion can be further used as a storage portion.

By providing a pinion gear, a rack portion, and the like, the storage stand can be operated either manually or electrically, and one of the pinion gears idles due to a lateral gap between adjacent storage stands while the storage stand is running. Even in such a case, the other pinion gear surely meshes with the rack portion, so that the storage base travels reliably without stopping. If this rack portion is configured with a large number of slits in the back plate material, the back plate material itself can also be used as the rack portion.

Further, if the horizontal base frame and the cover member are laid under the floor, the auxiliary roller can be rolled on the plastic cover member, so that noise caused by the rolling can be reduced. Also, if the main roller is configured so as to roll diagonally in contact with the corner where the weight supporting surface of the horizontal rail and the guide surface intersect, the inner end surface of the main roller will become the guide surface even at the corner of the horizontal rail. The storage base runs lightly and smoothly without rubbing.

The present invention will be described in detail below with reference to the drawings illustrating the embodiments.

FIG. 1 shows an embodiment of an underfloor storage device according to the present invention. This storage device is provided with a storage outlet 4 on a horizontal floor surface 8 such as a living room, kitchen, or entrance. Under the floor 5, there are provided endless horizontal rails 6 and a plurality of storage stands 7 ... which are interlockingly connected in an endless manner and which are sequentially sent to the storage port 4 along the horizontal rails 6. is there.

Specifically, the opening / closing door 1 is provided at the storage item outlet 4, and the storage item outlet 4 is arranged directly above the storage base 7.

Further, as shown in FIG. 2, the storage stand 7 has a horizontal holding portion 10, a pair of main rollers 11 and 11 running along the horizontal rail 6, and an outer side of the main roller 11. An auxiliary roller 12 that is provided to support the storage table 7 together with the main roller 11,
Is equipped with.

In the illustrated example, the holding portion 10 is formed by vertically erecting the left and right side edges of a flat plate material, and the front plate material 3 and the back plate material 13 are vertically fixed and attached. A basket 2 or the like into which small objects (not shown), tools, or other various kinds of stored items are put into or taken out from the holding unit 10 via the stored item take-out port 4 or is stored in a placing state, or the basket 2 or the like is used. The stored items are directly stored in the holding unit 10 without doing so.

As shown in FIGS. 2 and 3, the sub roller 12 is
A horizontal axis A is provided on the lower surface in the center of the front end portion of the holding portion 10 to the front plate member 3.
It rolls around a floor underside 14 which is rotatably provided around and on which a horizontal rail 6 is laid.

The main rollers 11 and 11 are attached to the lower side edges of the back plate member 13 via a pair of connecting pieces 15 and 15 and a support member 16 and the like. The connecting pieces 15 and 15 are pivotally mounted around the vertical axis B so as to be swingable and openable, and the side edges 7a and 7a of the adjacent storage bases 7 and 7 can be connected to each other so that they can approach and open each other. The rocking ends 19, 19 of the pieces 15, 15 are attached to the backs of the adjacent storage stands 7, 7 (back plate material 13).
Then, they stick to each other.

In this way, when the storage bases 7 ... Are stopped from traveling, the storage bases 7 ... Do not collide with each other due to inertia, and the lateral gap E between the adjacent storage bases 7 is minimized. Is possible. Therefore, it is possible to increase the number of storages 7 ...
The ratio of the storage table 7 to the installation space of the entire device increases, and the space can be effectively used.

As shown in FIGS. 4 and 5, the connecting piece 15 comprises a neck portion 18 having a through hole 17 having an oval cross section, and a swinging end portion 19 extending from the neck portion 18 in an expanding manner. All connecting pieces 15 ...
Can be used with the same shape and structure. That is, when connecting the storage stands 7 and 7 as shown in the figure, one of the pair of connecting pieces 15 and 15 is vertically inverted and used.

The support member 16 is provided in the through holes 17, 17 of the connecting pieces 15, 15.
The support member 16 and the connecting pieces 15, 15 are swingably connected to each other around the vertical axis B by inserting the shaft member 20 erected upright and connecting them by bolts and nuts or the like.

The support 16 has a downward bent portion 16a at both ends thereof,
16a is inclined inward, and the main roller 11 is rotatably attached to the downward bent portion 16a so that the end surface of the main roller 11 is along the inclined axis C. The tilt axis C is tilted at a predetermined angle with respect to the horizontal plane.

The shaft member 20 serves both to connect the connecting pieces 15 and 15 and to mount and support the support 16 and the main roller 11. Moreover, since the adjacent storage bases 7 and 7 also serve as the main roller 11, the number of parts can be reduced, and the manufacturing is easy and the cost can be reduced.

The horizontal rail 6 has a horizontal cross-sectional shape,
A pair of vertical guide surfaces 21, 21 closer to the center and the guide surfaces
A pair of horizontal weight supporting surfaces extending outward from the lower ends of 21, 21
22 and 22 are included.

The main roller 11 includes a weight support surface 22 and a guide surface 21.
The width is set in the axial direction corresponding to the width of the corner portion 23 where the main roller 11 intersects with the corner portion 23, and the main roller 11 is arranged so as to roll in contact with the corner portion 23 at an angle. The cross-sectional shapes of the rolling surface of the main roller 11 and the corner portion 23 are
It is preferable that they match as arcs.

In this way, even in the corner 6a of the horizontal rail 6 (see FIG. 3), the inner end surface of the main roller 11 does not rub against the guide surface 21, and the storage base 7 travels lightly and smoothly. The horizontal rail 6 and the main roller 11 can be prevented from being damaged, and a strong feeding force is not required.

Moreover, since the pair of main rollers 11 and 11 roll so as to sandwich the horizontal rail 6, it is possible to prevent the storage base 7 from rolling laterally during traveling. The horizontal rail 6 is preferably made of plastic, which has the advantage of reducing noise when the main roller 11 rolls.

However, as shown in FIG. 3, when the storage racks 7 travel on the corners 6a of the horizontal rails 6, the side edges 7a, 7a of the adjacent storage racks 7, 7 are mutually in contact with each other. When the storage bases 7, 7 are connected to each other by opening the legs about the swing axis of the connecting pieces 15, 15 and traveling along the linear portion 6b of the horizontal rail 6, the adjacent storage bases 7, 7 side edges 7a, 7
a closes each other and approaches in parallel.

As shown in FIG. 1, this storage base 7 rotates endlessly along a horizontal rail 6 and, when one storage base 7 is run, the other storage bases 7 ... Also runs and easily stores the desired storage base 7 in the storage port 4
Can be sent up to.

Further, as shown in FIGS. 2 and 6, the storage stand 7
... are configured to be manually fed. That is, the shaft 45 with the manual handle 44 and a pair of pinion gears that rotate in the same direction by the rotation of the shaft 45.

2 and 6 show an example in which the structure of the rack portion 26 is different. In FIG. 6, the rack portion 26 is constituted by rack gears, and in FIG. 2, as shown in FIG. A large number of slits 29 with which the pinion gears 25 are sequentially meshed are formed in the back plate member 13 at equal pitches in the horizontal direction, and the large number of slits 29 form a rack portion 26. By doing so, the back plate material 13 itself can be used also as the rack portion 26, and the number of parts is reduced. If this slit 29 ...
There is also an advantage that the cost can be reduced.

However, as shown in FIGS. 2 and 6, the manual handle 44 is provided with a knob 44a which can be freely raised and lowered so that the knob 44a is an obstacle when the door 1 is closed. We are careful not to become it.

The shaft 45 is pivotally attached to a mounting member 27 erected on the bottom surface 14 of the floor so as to be rotatable about a vertical axis F, and the mounting member 27 does not mesh with the pinion gears 25, 25. It is rotatably pivoted around the hearts D and D.

A drive gear 28 is fixed to the lower end of the shaft 45, and the drive gear 28 meshes with both pinion gears 25, 25.
Therefore, when the manual handle 44 is rotated, the pinion gears 25, 25 are rotated in the same direction via the drive gear 28, and the rotational movement is converted into linear movement by the rack portion 26 and sent to the storage table 7. Is given.

The pinion gears 25 and 25 are configured to mesh with the rack portions 26 and 26 of the adjacent storage bases 7 and 7 so as to mesh with the rack 26 at the same time and to straddle the lateral gap E.

Therefore, even if one of the pinion gears 25 idles due to the lateral clearance E while the storage table 7 is traveling by the rotation of the manual handle 44, the other pinion gear 25 always meshes with the rack portion 26. Even if there is a gap E,
The storage stand 7 ... runs reliably and continuously without stopping.

The drive parts such as the shaft 45 and the pinion gears 25, 25 may be omitted, and the feeding may be directly applied to the storage base 7 by hand or the like. Alternatively, the storage table 7 can be driven electrically instead of manually.
