Regarding the mechanism.

[Conventional technology]

As a means of effectively utilizing the space under the floor, a storage compartment is often provided in the space under the floor. Conventional underfloor storage is usually installed between boards in kitchen rooms, etc., and by attaching an opening/closing lid to a part of the floor and opening/closing the opening/closing lid, it is possible to store food items under the floor, for example, in a particular season. It is designed to store equipment that will only be used for a limited time.

[Problem that the invention attempts to solve]

However, the first problem with the above-mentioned underfloor storage is that the floorboard must be specially processed in order to provide the opening. In addition, each time you put something in or out of the storage, you have to lift the lid plate by hand, which is cumbersome. However, if a large opening/closing opening is provided, the space that can be effectively used in a kitchen room, etc. will be limited accordingly, so the problem is that an opening with a large area cannot be obtained. There is a second problem in that this occurs.

The present invention is an attempt to improve the above-mentioned problems, and it can be easily set without special processing on the opening of the floorboard, is easy to open and close, and has a large opening area. There is a problem to be solved in making it possible to obtain a storage room.

That is, the present invention is characterized in that the tatami mats are provided so that they can be opened and closed, and the tatami mats can be taken in and out of the storage by opening and closing the tatami mats.The specific means and operation thereof are as follows. It is.

[Means for solving the problem] An outer frame formed into a rectangular shape with an opening substantially the same as that of a tatami mat is attached to the floorboard.

A mounting plate is attached to the rear end of the outer frame via a connecting arm and a gas spring so as to be openable and closable in the longitudinal direction so as to cover the opening.

The connecting arm consists of a long arm and a short arm, with the long arm extending from the mounting plate toward the front end of the outer frame, and the short arm extending from the mounting plate toward the rear end of the outer frame. be established. That is, both ends of the connecting arm are pivotally connected to the outer frame and the mounting plate so as to expand in a V-shape.

A gas spring is interposed between the mounting plate and the outer frame so that it extends from the rear end of the mounting plate toward the front end of the outer frame, and the gas spring always points the mounting plate diagonally upward. and force it to open.

A locking metal fitting is fixed to the front end of the mounting plate, and a locking mechanism that can be freely engaged and detached from the locking metal fitting is attached to the inner wall of the front end of the outer frame, and the locking mechanism can be used to pull the wire extending outside. The engagement with the lock fitting can be released through the lock fitting.

[Effect]

When the lock fitting is engaged with the lock mechanism and the mounting plate is closed against the opening of the outer frame, pulling the lock mechanism wire releases the engagement and attaches the gas spring. The mounting plate opens upward through the force, creating a state in which the tatami is slightly raised. In this state, by lifting the front end of the tatami,
The state in which the tatami mat and the tatami mounting plate are opened is achieved through the biasing action of the gas spring and the action of the long arm and short arm of the connecting arm rising while rotating toward the front end (longitudinal direction).

An adjustment screw 16 is inserted into the insertion hole 15 through a through hole 17 opened in the mounting fitting 9, and the tip end of the adjustment screw 16 is screwed into the screw hole 13' so as to be freely retractable. That is, the concave surfaces 10 and 1 formed on the back side of the mounting plate 5
A mounting bracket 9 is attached to the mounting plate 1 with its claw portion 9' directed toward the inside of the mounting plate 5 so as to be movable forward and backward.
Mounting metal fittings 7 and 9 are provided on the surface side of the mounting plate 5.
The tatami mat 4 is fixed by biting into the claws 7' and 9' formed in the tatami mats 4. That is, the tatami mat 4 is installed in a position adjustable manner by adjusting the attachment fitting 9. Furthermore, a pair of support fittings 18, 18 extending in the front-rear direction (longitudinal direction) and having a U-shaped cross section are fixed to the back side of the mounting plate 5 with their openings facing downward. . One end of a connecting arm 20 is pivotally attached to one end of both support fittings 18 (on the mounting fitting 7 side). The connecting arm 20 is composed of a short arm 20A and a long arm 20B, and the short arm 20A extends toward the connecting part side (rear end side) of the mounting plate 5, and the other end is connected to the arm holder 25. It is pivoted at the rear end position. Further, the long arm 20B extends toward the opening side (front end side) of the mounting plate 5, and the other end is pivotally attached to the front end position of the arm receiving fitting 25. That is, the short arm 20A and the long arm 20B are connected so as to expand from the mounting plate 5 toward the outer frame 1 in a V-shape.

is attached, and one end of a gas spring 22 is pivotally attached to the spring attachment fitting 21. The gas spring 22 extends in the direction of the opening of the mounting plate 5, and the other end is fitted with a male thread 22' cut into the same part by screwing it into a threaded hole formed in the holder 27. It is pivotally attached to the receiving metal fitting 26. That is, by interposing the gas spring 22 between the mounting plate 5 and the outer frame 1, the mounting plate 5 is always biased upward (in the opening direction). Numeral 28 is a lock fitting fixed to the front end of the mounting plate 5, and a lock mechanism 29 is attached to the inner wall of the front end of the outer frame 1 in correspondence with the lock fitting 28. One end of the wire 30 is hooked to the tip of the lever portion 29' constituting the locking mechanism 29.
0 penetrates the side wall of the outer frame 1, and the other end is connected to the knob 31. That is, by pulling the knob 31, the locking mechanism 29 can be released from the locked state.

With the mounting plate 5 closed relative to the opening 1' of the outer frame 1, by pulling the knob 31 as described above, the lever portion 2 of the locking mechanism 29 is released.
9' can be rotated, thereby releasing the engagement between the lock fitting 28 of the mounting plate 5 and the lock mechanism 29. In this state in which the locking fitting 28 and the locking mechanism 29 are disengaged, the mounting plate 5 moves its rear end forward through the gas spring 22 that biases it diagonally upward, and the front end of the mounting plate 5 moves forward. A state is obtained in which it gradually opens upward. More specifically, the shot arms 20 are pivotally connected to the support fittings 18 of the mounting plate 5.
As the mounting plate 5 is opened upward, the long arm A and the long arm 20B rotate forward and gradually rise, while both arms 20A and 20B
A state is obtained in which the mounting plate 5 is opened upward as the opening/closing fulcrum.

On the other hand, when the mounting plate 5 is open with respect to the opening 1', by pressing the mounting plate 5 in the closing direction, the rear end of the mounting plate 5 is moved rearward and the short arm 20A and the long arm 2 are
A state in which 0B rotates backward is obtained.

[Effect of idea]

The present invention is constructed as described above.
As mentioned above, by opening and closing the mounting plate via the connecting arm consisting of the long arm and short arm and the gas spring, there is no need to perform any special processing on the opening.
When opening and closing the tatami mounting plate relative to the opening in the floorboard, it is possible to gradually open and close the tatami while shifting its position in the front and back direction, thereby making it smoother for other tatami mats adjacent to the tatami. It has now been possible to open and close the door easily and easily.

By providing the storage under the tatami as described above, it has become possible to obtain a storage with a large opening area the size of a tatami. In addition, by opening and closing the tatami in the longitudinal direction, a large space can be created between the opening end of the tatami and the opening of the outer frame, which allows for smooth loading and unloading of stored items in the storage compartment. I was able to do it.

Furthermore, by forming the outer frame and the tatami mounting plate as a unit, it can be easily installed under the floor, and can also be used for general purposes as an underfloor storage room or an underfloor storage box. I was able to do this.

In particular, in the case of the present invention, the mounting plate is always urged to open diagonally upward by a gas spring, and a locking fitting is fixed to the front end of the mounting plate, and a lock is attached to the locking fitting, which can be freely engaged and detached. The mechanism is attached to the inner wall of the front end of the outer frame, and the locking mechanism can be disengaged from the locking metal fitting by pulling the wire extending outside, so that it can be simply locked. A one-touch operation by simply pulling the wire releases the engagement of the locking metal fittings, and the mounting plate is opened upwards through the biasing force of the gas spring, allowing the tatami to rise slightly. It has now become possible to easily open the opening of the storage compartment without requiring special tools for lifting.
