Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an underfloor storage, and more particularly, to reduce the opening / closing force of a floor cover and to effectively use a wasteful storage space in the storage.

[0002]

[Prior Art]

 One of the things that effectively utilize the space under the floor is an underfloor storage. In the underfloor storage, an opening frame is attached to the floor, and a storage room communicating with this opening is provided under the floor. A floor lid that can be opened and closed is rotatably attached to the opening frame via hinges, etc.The floor lid also functions as a floor plate when the storage chamber is closed, so it is manufactured with a certain strength and thickness. The floor cover has a certain weight. By the way, when the floor cover is opened, it is desirable that the floor cover keeps the opened state for the work of taking in and out the stored items. To do this, for example, rotate the floor lid when opened to the opposite side from the vertical state, and install an arm rod (stopper arm, etc.) that regulates the rotation at a fixed position across the side surface of the floor lid and the opening frame. A structure is possible in which the floor cover is kept open by the weight of the floor cover itself that has been rotated to the opposite side.However, with this structure alone, the floor cover will not be opened when the floor cover is pushed unexpectedly during the loading and unloading of stored items. There is a risk of accidental fall. Therefore, the arm rod is further provided with a restricting means, and the restricting means locks the arm rod immovably in the final opened state of the floor cover so that the floor cover does not fall down unless the restricting means is released. Collection and delivery are devised. In such an underfloor storage, since the opening / closing operability of the floor lid is not deteriorated, for example, a mechanism that can release the restricting means with one hand is provided to ensure the safety and operability of the underfloor storage. There is.

On the other hand, the area of the storage room is determined by the combination of the floor cover and other structural parts at the position where the underfloor storage is arranged. In addition, the height of the storage room (depth from the floor) is within the range where the bottom can be easily reached with the hand extended from the floor because of the ease of taking out the stored items. To be done. Therefore, the height of a general bottle container (beer bottle, etc.) that is frequently stored is sufficiently secured, and an extra space is generally formed between the upper end of the bottle container and the floor cover.

[0004]

[Problems to be solved by the device]

 Since the floor cover of the underfloor storage also functions as a floor plate when the storage room is closed, it is manufactured with a certain strength and has a certain weight. Therefore, a certain amount of operating force is required to open and close, and the opening and closing operations were not easy, especially for housewives who are frequently used. Further, in order to prevent the floor cover from accidentally falling during the operation of taking in and out of stored items, the arm rod is provided with a restricting means or the like. However, attaching the arm rod to the floor cover and further providing the restricting means on the arm rod complicates the mechanism, which also increases the manufacturing cost. On the other hand, since the floor cover is manufactured with a certain strength, it has a certain thickness. In addition, the height of the storage room is such that the bottom can be reached when reaching out from the floor, so when a general bottle container is stored, the upper edge of the bottle container and the floor cover are An extra space is formed between them, and the space corresponding to the thickness of the floor cover and the extra space are wasted.

The present invention has been made in view of the above circumstances, and provides an underfloor storage in which the floor cover can be easily opened and closed with a small operating force, and the waste space of the storage chamber can be effectively used. The purpose is to improve operability and storage efficiency.

[0006]

[Means for Solving the Problems]

 The structure of the underfloor storage according to the first invention for achieving the above object is to provide an opening frame on the floor, provide a storage room communicating with the opening frame under the floor, and attach a floor cover to the opening frame so as to be openable and closable. In the underfloor storage, one end of the damper mechanism that urges the floor lid in the opening direction is rotatably attached to the storage chamber side, and the other end is rotatably attached to the floor lid, and the floor lid is closed. It is characterized in that a hooking means for holding the floor lid in the opening frame in an unopenable manner is provided between the opening frame and the floor lid. The configuration of the underfloor storage according to the second invention comprises the configuration of the underfloor storage according to the first invention, and the storage section arranged on the storage chamber side with the floor cover closed is It is characterized by protruding on the back side.

[0007]

[Action]

 In the underfloor storage according to the first invention, when the hooking means is released, the floor cover held by the opening frame is urged in the opening direction by the damper mechanism, and the force for opening the floor cover is reduced. At the same time, the floor lid is held in the final extended state of the damper mechanism, and the floor lid does not fall in the closing direction due to its own weight. Also, when closing the floor cover, the damper mechanism exerts an urging force against the closing direction on the floor cover, reducing the force that supports the floor cover (the force that supports it in the pulling up direction), and the floor cover closing operation is light. Becomes In the underfloor storage according to the second invention, the storage section is provided on the back surface of the floor cover so that the storage section is disposed in the extra space (useless space) of the storage room with the floor cover closed, and The space becomes a storage part and the storage efficiency increases. Also, even if the weight of the stored items increases, the floor cover is urged in the opening direction by the damper mechanism, and the floor cover opening / closing operation force is reduced.

【Example】

 Hereinafter, a preferred embodiment of an underfloor storage according to the present invention will be described in detail with reference to the drawings. 1 is a side view showing an underfloor storage according to the present invention, FIG. 2 is a plan view showing a floor cover, and FIG. 3 is a perspective view showing an opening stopper. As shown in FIG. 1, a rectangular opening frame 3 is attached to the floor 1, and a storage chamber 5 is arranged below the opening frame 3. One end surface (rear end surface) of the floor cover 7 is attached to one side of the opening frame 3 through a hinge 9, and the floor cover 7 is rotatably opened and closed through the hinge 9. With the floor cover 9 closed, the storage chamber 5 is closed so that the upper surface is flush with the floor 1. A supporting metal 11 is provided on the side end surface of the floor cover 7 in parallel with the side end surface. The support metal 11 is provided with a long hole 13 extending in the longitudinal direction of the side end face, and a widened portion 13a is formed on the front end face side of the floor cover 7 of the long hole 13.

By the way, a damper mechanism is provided on the side wall of the storage chamber 5. As an example of this damper mechanism, a cylinder 15a side of an air damper 15 in which a biasing member such as a pressurized gas or a coil is incorporated is rotatably attached. The telescopic shaft 15b is extended from the cylinder 15a of the air damper 15, and the tip of the telescopic shaft 15b is rotatably engaged with the elongated hole 13 of the stopper plate 11. The telescopic shaft 15b urges the floor cover 7 to the open state against the weight of the floor cover 7 by the urging member in the cylinder 15a. This urging force is adjusted so that the operation force of the floor cover 7 in the opening direction is minimized. In other words, the floor cover 7 can be opened by pulling it with a slight force. Further, by engaging the tip end of the telescopic shaft 15b with the widened portion 13a of the elongated hole 13, the engagement can be released from the stopper plate 11. Therefore, by removing the telescopic shaft 15b from the stopper plate 11, the floor cover 7 can be opened and closed without the biasing force of the air damper 15. Further, a stopper 17 is provided on the rear end surface of the floor cover 7 and the opening frame 3 so as to extend over the both, and the stopper 17 regulates the opening angle of the floor cover 7 so that the air damper 15 does not extend beyond the maximum extension. There is. As shown in FIGS. 2 and 3, an opening stopper (rotation lock) 19 as a locking means is provided on the front end surface side of the floor cover 7, and the rotation lock 19 keeps the floor cover 7 in a closed state. It is designed to hold.

As described above, according to the underfloor storage 21 according to the above-described embodiment, since the floor cover 7 is biased by the air damper 15, the operation when the floor cover 7 is opened is extremely light. In addition, since the floor cover 7 is held in the extended state of the air damper 15, there is no need to provide a regulation means for holding the floor cover 7 in the open state, and the opening holding mechanism is extremely simple. Can be

Next, another embodiment of the present invention will be described with reference to FIG. FIG. 4 is a side view showing a floor cover portion of an underfloor storage according to another embodiment. A storage portion 33 is formed on the back surface (the storage chamber 5 side) of the floor lid 31, and the storage portion 33 can store long bottles, small articles, and the like. The storage portion 33 is adapted to project into a spare space (neutral space) formed between the upper end of the bottle container and the floor lid 31 when storing a general bottle container. The storage / removal port of the storage portion 33 is formed by, for example, opening the front end surface 33a of the storage portion 33. Further, the storage / inlet opening may be provided on the front surface side of the floor cover 31 with an opening area that does not reduce the strength, and the small cover 35 (indicated by a broken line in FIG. 4) may be attached so as to be opened and closed. In this case, articles and the like can be taken in and out by opening only the small lid 35 without opening and closing the floor lid 31, and the small articles can be stored reasonably by partitioning them appropriately by the partition plate 33b. be able to. If a tray (not shown) is arranged in the storage portion 33, each tray can be taken in and out.

Also in the present embodiment, as in the above-described embodiments, the air damper 15 is attached across the side wall of the storage chamber 5 and the floor cover 31. However, in the present embodiment, since the stored items are stored in the storage portion 33 of the floor lid 31, and the weight of the stored items increases the opening / closing operation force of the floor lid 31, the urging force of the air damper 15 also depends on this opening / closing operation force. Have been greatly adjusted.

According to the underfloor storage 37 according to this embodiment, since the floor cover 31 is formed with the storage portion 33 that uses the spare space of the storage chamber 5 (see FIG. 1), small articles and the like are stored in the storage chamber 5. It is possible to improve the storage efficiency of the storage chamber 5 without storing it. Furthermore, even if the storage unit 33 stores the stored items, the floor cover 31 can be opened and closed with a small opening / closing force, as in the above-described embodiment.

In the above-mentioned two embodiments, the air damper 15 is used to assist the opening / closing operation of the floor covers 7 and 31, but the air damper 15 adjusts the urging force to adjust the floor cover 7 and 31. Alternatively, the opening of 31 can be performed only by the urging force of the air damper 15. In this case, the floor covers 7 and 31 are held in the closed state on the opening frame 3 side by the rotation lock 19, and the floor covers 7 and 31 are automatically opened only by releasing the rotation lock 19.

[0015]

As described in detail above, in the underfloor storage according to the present invention, a damper mechanism for urging the floor cover in the opening direction is provided between the storage chamber side and the floor cover, and the floor cover is opened. Since the floor cover is provided with a hooking means to hold it on the frame, the floor cover is opened very easily by the urging force of the damper mechanism, and the floor cover is held in the final extended state of the damper mechanism so that the floor is supported by its own weight. It is possible to prevent the lid from falling in the closing direction. As a result, the floor cover can be prevented from collapsing with a simple structure, and the floor cover can be easily opened and closed with a small operation force, so that the manufacturing cost can be reduced and the operability can be significantly improved. In addition, since the storage part that protrudes toward the storage room with the floor cover closed is provided on the back side of the floor cover, the storage part can be installed in the storage space with the floor cover closed. Space), a part of the storage room that was previously wasted space can now be used as a storage unit. As a result, the storage efficiency can be significantly improved.
