CONSTITUTION:With a piston rod being pushed out by the driving of a drive power source 16 of a lifting device, links 17 and 18 are made to swing, gradually becoming perpendicular, for pushing up of a lifting bottom board 14 together with pushing-up parts 15. Then, main opening rods 3 swing clockwise around axes 5, making sliders 6 slide along slits of slide parts 7. Sliders of sub-opening rods 4, then, slide rightward on a slide rails, making the sub-opening rods 4 swing around axes 10. Thereby, a piece Fa of a floor board is lifted almost in parallel with the floor plane. As the piece Fa of the floor board swings clockwise further against the floor board F, an opening is opened.

Description

Detailed Description of the Invention [Industrial Field of Application] The present invention provides a method for opening and closing a floorboard piece for loading and unloading an underfloor storage, by first lifting the floorboard piece horizontally and opening it approximately 90 degrees, and then This invention relates to an underfloor storage cabinet in which the whole thing can be raised to efficiently take in and take out stored items.

[Conventional technology and its problems]

In recent years, underfloor storage has been widely used in residential buildings. Especially when the underfloor storage is used in a tatami room or a Western-style room, 1
Tatami mats and floorboards are used as lids for underfloor storage, but they are heavy and require great effort and difficulty to open and close by hand.

Furthermore, in tatami rooms, when opening and closing the lid, the tatami mats may rub against the surrounding tatami mats, causing inconveniences such as being difficult to open and damaging the edges of the tatami mats when opened and closed frequently.

Furthermore, when storing under the floor, although large items can be stored, the user must bend down to take them in and out, making it difficult for elderly people and children to take them out.

[Means for Solving the Problems] Therefore, in order to solve the above problems, the inventor has conducted extensive research and has developed the invention by providing a floor plate piece that can be opened and closed on the top surface of the storage cabinet body, and a main opening/closing rod. One end is pivotally supported at an upper position on one side of the storage main body, the other end of the main opening/closing rod is slidably provided on the lower surface of the floor plate piece via a slider, and one end of the sub opening/closing rod is The main opening/closing rod is pivotally supported on the lower surface of the floor plate near the pivot point, the other end is pivotally supported at the upper position on the other side of the storage body, and the main opening/closing lever is mounted in a slide rail provided at an appropriate position on the secondary opening/closing lever. A slider fixed to the middle of the opening/closing rod is slidably provided, or, in the above configuration, a push-up rod is provided between the floor plate piece and the elevating bottom plate that can be raised and lowered within the storage main body by a drive source. By making it an underfloor storage, when opening and closing the floorboard pieces for loading and unloading the underfloor storage, the floorboard pieces are first lifted horizontally and opened approximately 90 degrees, and then the entire item to be stored is raised and the items to be stored are removed. This allows for efficient loading and unloading, and solves the above-mentioned problems.

[Effect]

The operation will be described with respect to a configuration in which a lifting bottom plate 14 is provided by the lift device WB. First, as the piston rod advances, the links 17 and 18 gradually become vertical, and the elevating bottom plate 14 rises.At the same time, the push rod 15 is pushed up, and at the same time, the main opening and closing rod 3. The floor plate piece Fa can be opened under the control of the sub-opening/closing rod 4.

To explain this specifically, the drive source 16 of the lift device B
is driven to advance the piston rod, whereby the links 17, 18 are driven vertically in stages, and the elevating bottom plate 14 is raised accordingly.

At the same time, the push rod 15 also rises. Then, the main opening/closing rod 3 rotates clockwise around the 5 pivot points, and as the main opening/closing lever 3 rotates, the auxiliary opening/closing lever 4 rotates around the 10 pivot points via the slider 12. The floor plate piece Fa is lifted up substantially in parallel, and from this state, the floor plate piece Fa is then rotated clockwise and opened to the floor plate F (see the solid line in FIG. 9).

What is particularly important in this series of operations is that the floor plate piece Fa opens only when the elevating bottom plate 14 is raised. Further, when closing the floor plate piece Fa, the elevating bottom plate 14 of the lift device B may be lowered.

〔Effect of the invention〕

First, in the invention of claim 1, a floor plate piece Fa that can be opened and closed is provided on the upper surface of the storage main body 1, and one end of the main opening/closing rod 3 is pivoted 5 at an upper position on one side of the storage main body 1. , the other end of the main opening/closing rod 3 is connected to the floor plate piece Fa via the slider 6.
One end of the sub-opening/closing lever 4 is attached to the upper and lower surface pivots 8 of the floor plate piece Fa near the five pivot points of the main opening/closing lever 3, and the other end is attached to the other side of the storage main body 1. Pivot l in the upper position of
Firstly, by creating an under-floor storage compartment in which a slider 12 fixed to the middle of the main opening/closing rod 3 is slidably provided in the slide rail 4a provided at the appropriate position of the sub-opening/closing rod 4. The first piece Fa can be opened and closed horizontally, and secondly, even if the floor plate piece Fa is left wide open, it is suitable for being installed in approximately contact with the wall W of a room such as a tatami room.

To explain these effects in detail, the floorboard piece Fa, which is the substrate of the loading/unloading capacity A, is provided so as to be openable and closable by the main opening/closing rod 3 and the sub opening/closing rod 4. In particular, in the present invention, one end of the main opening/closing rod 3 is connected to the A pivot 5 is mounted at a convenient upper position of the storage main body 1,
The other end of the main opening/closing rod 3 is slidably provided on the lower surface of the floor plate piece Fa via a slider 6, and one end of the auxiliary opening/closing rod 4 is attached to the floor plate near five pivot points of the main opening/closing rod 3. A slide rail 4 with one side Fa having a shaft support 8 on the upper and lower surfaces, the other end having a shaft support 10L at an upper position on the other side of the storage main body l, and a slide rail 4 provided at an appropriate position of the sub-opening/closing rod 4.
Since the slider 12 fixed to the middle of the main opening/closing rod 3 is slidably provided in a, as shown in FIG. and sub-opening rod 4
By setting a part of 01 to 01 and dl to the upper part of the storage main body l, it becomes a slider crank mechanism with a four-section rotation chain. By setting I2 to b2, a part of the main opening/closing rod 3 to c2, the suberiko 6 to d2, and the upper part of the storage body l to e, another five-section rotating chain double slider crank can be created. Both of them are constructed asymmetrically with the 12 sliders as boundaries, and the four-bar link and the five-bar link work together, and in particular, the four ends of the sub-opening and closing rod are Since it is pivoted 10, the fulcrum point for opening and closing of the floorboard piece Fa does not move to the right in FIG.
A can be pushed up while making it horizontal, and as a result, the floorboard piece Fa first rises substantially parallel and then opens, so there is less time for it to rub against the surrounding tatami T, allowing for smooth opening and closing. Furthermore, in a tatami room or the like, the edge of the tatami T will not be damaged.

Also, even with such four-section links and five-section links,
Since the five-bar link is completely regulated by the swing angle of the four-bar link (see FIG. 10), the floor plate piece Fa can be opened and closed with extremely regular and smooth movements.

Furthermore, in the present invention, even when the floorboard piece Fa is opened, the eight pivot points in the open state are between the base position and the path, and are vertical in this state. There is an advantage that the underfloor storage can be installed close to the wall W, and even in this case, the floor plate piece Fa can be opened sufficiently wide, thereby making it easy to take in and out the stored items.

Next, in the invention of claim 2, in contrast to the invention of claim 1, a push rod 15 is provided between the lifting bottom plate 14 which can be raised and lowered within the storage main body 1 by a drive source 16 and the floor plate piece Fa. By adding the configuration in which the floorboard piece Fa is opened, the stored items also rise at the same time, resulting in effects such as being able to efficiently take in and out the stored items.

That is, the floor plate piece Fa is opened and closed by a push-up lever 15 provided between the floor plate piece Fa and the liftable bottom plate I4, which can be raised and lowered, of a lift device B provided in the storage main body 1. As it rises, the floor plate piece Fa is opened by the push-up lever 15, and at the same time, the stored items rise above the storage main body l, making it extremely easy to take in and take out the stored items, and the stored items in the under-floor storage are lowered. Even if it is on the side, it has the greatest advantage of being extremely efficient in loading and unloading.

The other configurations are the same as the invention of claim 1, and the same effects can be achieved.
