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 to a substantially horizontal position and lifting it up to approximately 90 degrees.
The present invention relates to an underfloor storage cabinet that can be opened and the entire stored item raised to efficiently take in and out the 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, 5
Tatami mats and floorboards are used as the fittings for the 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 extremely 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, and the other end is slidably provided at the upper position on the other side of the storage main body via a slider, and The underfloor storage is provided with a push-up rod 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 in the above configuration. Therefore, when opening and closing the floorboard pieces for loading and unloading the underfloor storage, the floorboard pieces are first lifted to a nearly horizontal state and opened approximately 90 degrees, and then the entire stored item is raised, allowing for efficient loading and unloading of stored items. This solves the problems mentioned above.

〔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 suberiko 6.
One end of the sub-opening/closing rod 4 is supported 8 on the FaT surface of the floor plate piece near the five pivot points of the main opening/closing rod 3, and the other end is placed in the housing via a slider 10. The underfloor storage is provided slidably at the upper position on the other side of the storage body 1, and the middle of the main opening/closing lever 3 and the middle of the auxiliary opening/closing lever 4 are pivoted. Fa can be opened extremely widely, secondly, the floorboard piece Fa can be opened and closed smoothly, and thirdly, it is suitable to set it in the center of a room such as a tatami room.

To explain these effects in detail, the floor plate piece Fa, which is the substrate for the tatami mat for loading and unloading, is provided so that it can be opened and closed by the main opening/closing lever 3 and the sub opening/closing lever 4. In particular, in the present invention, one end of the main opening/closing lever 3 is A pivot support 5 is provided at an upper position on one side 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 piece near five pivot points of the main opening/closing rod 3. It is pivoted 8 on the FaT surface, and the other end is slidably provided at the upper position on the other side of the storage main body 1 via a slider 10, and between the main opening/closing rod 3 and the auxiliary opening/closing rod 4. As shown in FIG. 10, a part of the main opening/closing rod 3 is a, a part of the auxiliary opening/closing rod 4 is 01, a slider lO is 01, and the main opening/closing rod 1 is a. By setting the upper part of ``d'', it becomes a slider crank mechanism with one four-section rotation chain 1, and a part of the sub-opening/closing rod 4 is ``a!''. By setting a part of the main opening/closing rod 3 as b, the slider 6 as 08, and the upper part of the storage main body 1 as d2, another four-section rotating chain slider crank mechanism is constructed. Since both of them are connected symmetrically around the 12 pivot points, due to the presence of 82 points of the slider 6, this is connected to the main opening/closing rod 3.
．． At the end of the rotation of the sub-opening/closing rod 4, it is positioned above and rearward of the five pivot points, so that the floor plate piece Fa is shifted rearward from the position directly above the storage main body 1.
There is an advantage that the floorboard piece Fa can be opened wide (fifth
(See the chain line in Figure 9 and the solid line in Figure 9).

Next, as shown in FIG. 11, when the eight pivot points open, the shaft traces are almost vertical in the initial stage if the sliding distance per unit time of the slider 10 is small. In the latter stage, the sliding distance per unit time increases and the slider 10 draws an arc to the right. As a result, the floorboard pieces Fa first rise approximately parallel to each other and then open, so there is less time for them to rub against the surrounding tatami mats, allowing smooth opening and closing, and furthermore, preventing damage to the edges of the tatami mats. do not have.

Furthermore, in the present invention, since the opening of the floorboard piece Fa can be widened, it is not only easy to store items to be stored, but it is particularly suitable to set it in the center of a room such as a tatami room.

Next, in the invention of claim 2, for the configuration,
An elevating bottom plate 1 that can be raised and lowered within the storage main body 1 using a drive source 15
By adding a configuration in which a push-up rod 14 is provided between 3 and the floor plate piece Fa, the stored items also rise at the same time as the floor plate piece Fa opens, resulting in effects such as efficient loading and unloading of stored items. play.

That is, the floor plate piece Fa is opened and closed by a push-up rod 14 provided between the floor plate piece Fa and a liftable bottom plate 13 that can be raised and lowered by 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 rod 14, and at the same time, the stored items rise above the storage main body 1, making it extremely easy to take in and take out the stored items, and the stored items in the underfloor storage are lowered. Even if it is on the side, it has the biggest advantage of being able to be pulled in and taken out efficiently.

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