Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to the structure of an underfloor storage device in which a storage container for storing articles is arranged using the space under the floor.

[Prior art] As a conventional underfloor storage device, for example,
Some of these are disclosed in Publication No. 50430 and Publication of Utility Model Publication No. 54-28250. In the device disclosed in Japanese Utility Model Application Publication No. 54-50430, the storage container is mounted on rails placed under the floor so that it can run freely, and the opening in the floor corresponds to the opening on the top of the storage container so that items can be taken in and out of the storage container. It's getting old. The device disclosed in Japanese Utility Model Publication No. 54-28250 is designed so that a storage container placed under the floor can be taken out together with the storage container.

[Problems to be solved by the invention] The container disclosed in Japanese Utility Model Application Publication No. 54-50430 cannot be taken out on the floor, so it is convenient for storing valuables and fragile items, but the container must be taken out by bending over. Therefore, there is a problem that it is inconvenient to take out small items or items that are frequently used. Also, Kimiaki Sane
The device disclosed in Japanese Patent No. 54-28250 allows the storage container to be taken out onto the floor, making it convenient for storing small items and frequently used items, but there is a problem in that it is difficult to store valuables and fragile items.

[Means for Solving the Problems] In order to solve both of the above problems, both functions are provided. In other words, the roller of the first storage container is inserted into the rail having a U-shaped cross section through the notch, and the roller is prevented from coming off by the retaining means, so that the first storage container cannot be easily pulled out upward from the rail. The second storage container is removably fitted to the frame so that the second storage container can be easily taken out upward from the frame mounted on the rail so that it can run freely. By providing both the first storage container that cannot be easily taken out on the floor and the second storage container that can be easily taken out on the floor, the first storage container and the second storage container can be used separately for storage. It has become possible to eliminate the problem by taking advantage of the strengths of both conventional examples.

[Example] Reference numeral 4 is a rail having a U-shaped cross section, and ribs 4a are formed over the entire length at the upper and lower edges of the side opening.
A pair of rails 4 is fixed to a rail receiving material 11 such as a large drawer, a joist, or a bundle under the floor 5. An opening 2 is formed in the floor 1 above between the pair of rails 4.
A receiving frame 12 is attached to the edge of the lid 3, and a lid frame 13 on the outer periphery of the lid 3 is placed on the receiving frame 12.
It can be opened and closed freely. A notch 7 is provided in each of the upper horizontal pieces 6 of the pair of rails 4, and this notch 7 is located below the opening 2. This notch 7 is provided with a leaf spring 8 as an example of a retaining means.
In other words, one end of the leaf spring 8 that closes the notch 7 in the same direction as the longitudinal direction of the rail 4 is fixed to the rail 4, and the other end of the leaf spring 8 is used as a free end to close the notch 7. It is made to be able to be pushed in against the elasticity of the leaf spring 8. In the figure, reference numeral 9 denotes a first storage container, and rollers 10 are rotatably protruded from both sides of the upper part. Here, the notch 7 is larger than the diameter of the roller 10. The opening 2 is sized to accommodate a first storage container 9 and a second storage container 19, which will be described later. 14 in the figure is the first
An inner lid 15 is detachably attached to the upper opening of the storage container 9, and a ventilation opening is provided in the first storage container 9. Reference numeral 19 in the figure denotes a second storage container, and the second storage container 19 is removably fitted to the rectangular frame 18 by placing a flange 21 on the frame 18. On both sides of this frame 18, rollers 20, which are the same as the rollers 10 described above, are protruded from both sides. Here, 22 is an inner lid detachably attached to the upper opening of the second storage container 19, and 23 is a ventilation opening provided in the second storage container 19. In addition, 16 in the figure is a stopper, which is arranged between the ends of a pair of rails 4,
Fixing parts 17 at both ends of the stopper 16 are fixedly attached to the rail 4 to prevent the rollers 10 from jumping out from both ends of the rail 4 in the longitudinal direction. Then, insert the first storage container 9 through the opening 2,
Place the roller 10 on the upper horizontal piece 6 of the rail 4 and position it above the leaf spring 8 as shown in FIG. Since the roller 10 is pushed into the rail 4 in this state (or the leaf spring 8 is automatically tilted as shown in FIG. 6 due to the load applied to the roller 10), the roller 10 enters the rail 4. roller 1
When 0 enters the rail 4, the leaf spring 8 returns to its original horizontal state due to its elastic restoring force, closes the notch 7, and is prevented from coming off upward by the leaf spring 8. Also, the roller 2 of the frame 18 fitted with the second storage container 19
0 is put into the rail 4 in the same way as the roller 10 of the first storage container 9.

Next, the operation of the underfloor storage device configured as described above will be explained. Remove the lid 3 and move the first storage container 9 and the second storage container 19 along the rail 4.
When the storage container 9 is positioned under the opening 2, the inner lid 14
You can remove the storage container 9 and put the stored items in the first storage container 9.
It can be taken out from the storage container 9. At this time, the first storage container 9 cannot be easily removed from the rail 4, so if valuables are stored at the bottom of the first storage container 9, there is less risk of theft. If you put the first storage container 9 up, it will not break by mistake (in other words, even if you accidentally try to lift the first storage container 9, it will not come off the rail 4, so it will not be subject to impact unlike the case with storage containers that can be lifted upwards) . Furthermore, when the second storage container 19 is positioned under the opening 2, the second storage container 19 can be pulled upward from the frame 18 as shown by the imaginary line in FIG. 7, and the stored items can be stored on the floor 1. You can also take out stored items. Therefore, it is possible to put in and take out stored items in a comfortable posture, which is convenient when storing small items or when taking out stored items from the bottom.

[Effects of the Invention] As described above, the present invention arranges a pair of rails having a U-shaped cross section under the floor in parallel so that the openings face each other,
Rotatable rollers are protruded from both sides of the first storage container, and the rollers are inserted into the rail having a U-shaped cross section through the notches on both sides, and the rollers are prevented from coming off by the retaining means, so that the rollers are moved in the longitudinal direction of the rail. Since it is attached so that it can be moved freely, the first storage container cannot be easily removed from the floor, and valuable items can be stored in the first storage container to reduce the risk of theft, or fragile items can be stored in the first storage container. It has the advantage of being able to prevent fragile items from breaking when placed in a container, and furthermore, rotatable rollers are protruded from both sides of the frame to which the second storage container is removably fitted, and these rollers can be freely run on rails on both sides. The second storage container can be easily removed from the frame and taken out onto the floor, as the frame is mounted so that it can move freely in the longitudinal direction of the rail, allowing for the insertion and removal of small items and the storage of items at the bottom. It has the advantage that it can be done in a comfortable position, and by using the first storage container and the second storage container properly depending on the purpose, it can be used conveniently without causing problems like the conventional example. In addition, below the opening, a notch large enough to allow the roller to be taken in and out up and down is provided in the upper horizontal piece of the rail having a U-shaped cross section, and a stopper means is provided to prevent the roller in the rail from slipping upward through this notch. Since it is provided in the notch, even if the first storage container or frame is installed so that it cannot easily fall out upwards from the rail, the first storage container or frame can be inserted through the opening and the rollers on both sides can be inserted into the notch. The rollers can be easily attached to the rails so that they can run freely.
