Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a device for opening the lid of an underfloor storage, which is mainly used as a lid for opening and closing tatami mats. Moreover, it is related to technology that facilitates the opening operation.

[Background Art] Conventionally, Japanese-style underfloor storage has been proposed in which the opening of the underfloor storage main body is opened and closed using a tatami mat as a lid. The handle of the tatami mat is used to hook the bottom surface of the edge of the tatami mat via a stopper and lift it up to open it. The problem was that it required a lot of effort.

[Purpose of the invention] The present invention was made in view of the above problem, and its purpose is to forcefully drive and lift the heavy lid at the beginning of opening, without damaging the heavy lid. To provide a device for opening the lid of an underfloor storage, which can be easily operated.

[Disclosure of the invention] The underfloor storage lid opening device of the present invention is placed in close proximity to other adjacent flooring materials of the underfloor storage main body 1, so that the distance between the lid and the other flooring materials is small. , a forced drive lift that lifts and moves the lid A, which is rotated to open and close, and which is closed flush with other adjacent flooring materials when in the closed state, approximately horizontally by electric drive to a certain height at the beginning of opening. means B, and an opening/closing force assisting means for assisting the opening/closing operation of the lid A, which is comprised of a rotation link mechanism for rotating the lid A to open and close it, and a gas spring 13; The opening/closing operation force auxiliary means are arranged on both sides of the rear side of the opening 2 which serves as a fulcrum, and the forced drive lifting means B is arranged in the middle of the front edge of the opening 2. With this configuration, the above object has been achieved. In other words, when the lid A starts to open, the structural drive lifting means B lifts the lid A to a certain height, so even if the lid A is heavy, such as a tatami mat, it can be hung with a dondol or the like and damaged. This allows the opening operation to be performed easily without having to do anything.

Embodiments of the present invention will be described in detail below based on the drawings.

Assists the opening and closing operation of the tatami mat 3 as the lid A at the end on the rotation center side of the tatami mat 3 which is rotated and opened and closed by the opening 2 having the opening area of one tatami mat 3 of the underfloor storage main body 1. A link mechanism, a gas spring 13, etc. are arranged as opening/closing operation force assisting means. Here, as shown in FIG. 1, the opening/closing operation force assisting means are arranged on both sides and rear sides of the opening 2, which serves as the rotational fulcrum of the lid A. In Fig. 1, a first link 4 is installed between a support 10 attached to the tatami mat 3 side and a support box 11 attached to the underfloor storage main body 1 side, with both ends thereof pivotably connected. . One end of the second link 5, which is longer than the first link 4, is pivotally connected to the tatami mat 3 on the rotation tip side of the pivot connection point a of the first link 4. The other end of the second link 5 is slidably engaged with a horizontally elongated hole 6 formed in the underfloor storage main body 1 via a roller 12. A connecting link mechanism 8 is connected between the first link 4 and the second link for moving the loose end 7 of the second link 5 toward the rotation center of the elongated hole 6 as the first link 4 rises and swings. It is pivotally connected between the links 5 so as to be rotatable. The connection link mechanism 8 includes a link 8a whose one end is pivotally connected to the middle of the second link 5, and an extension link which is integrated with the first link 4 and extends from the end of the first link 4. 8b, this extending link 8
b and link 8a are rotatably connected, but the configuration of such connecting link 8 can be modified in various ways.

According to such a configuration, the end of the second link 5, which is longer than the first link 4, can slide freely into the horizontally long elongated hole 6 formed on the underfloor storage main body 1 side. and a connecting link mechanism 8 for causing the loose end 7 of the second link 5 to travel toward the rotation center side of the elongated hole 6 as the first link 4 rises and swings.
In order to open the closed tatami 3 by pivotally connecting the first link 4 and the second link 5, the steps shown in FIGS. 3a, b, and c and FIG. As shown in FIG. 2, as the first link 4 rotates upright, the loose end 7 of the second link 5, which is longer than the first link 4, runs along the elongated hole 6 toward the center of rotation. , due to the standing rotation of the second link 5 due to this running,
At the initial stage of lifting, the tatami 3 is lifted approximately parallel, thereby avoiding the edge of the tatami 3 from being strongly rubbed against the edge of the opening 2, and preventing damage to the tatami 3 during opening and closing. . The connecting link mechanism 8 suppresses the swinging of the long second link 5, so that the opened tatami mat 3 can be stably held without shaking.

Then, the support body 10 of the tatami mat 3 and the underfloor storage main body 1
A gas spring 13 as an example of the holding means 9 is interposed between the support boxes 11 of the tatami mats 3.
The opening/closing rotation position can be maintained in such a manner that it can be lifted up and turned down with a light force. Such a gas spring 13 seals high-pressure gas in a cylinder tube 14, movably inserts a piston (not shown), connects a piston rod 15 to the piston, and opens and closes a valve formed on the piston. Therefore, the piston rod 15 is pushed up by the gas pressure in the gas chamber on the bottom side to lightly lift the tatami 3, and then the piston rod 15 is inserted into the cylinder tube 13 by a pushing force exceeding a certain level, and the tatami 3 can be pushed down lightly. This is how it was done. A well-known gas spring 13 is used. The valve operation of the piston is preferably linked to the lifting and pushing down of the tatami 3.

In the embodiment, a gas spring is used as the holding means 9, but it goes without saying that other structures may be used.

In the above configuration, the sound idea is to provide a forced drive lifting means B that lifts and rotates the tatami mat 3 serving as the lid A to a certain height at the beginning of opening. This allows the lid A to be lifted to a certain height, so that even if the lid A is heavy like a tatami mat 3, subsequent opening operations can be performed easily. The specific configuration will be explained in detail below.

As shown in FIGS. 5 and 6, a rotating plate 17 is rotatably supported on a base 16 by bearings 18, and rotated via a group of reduction gears 20 by the rotation of an electric motor 19 using a battery as a power source. The plate 17 can be rotated. A lower link 21 is attached to a pin 22 eccentrically from the center of rotation of the rotating plate 17.
It is pivotally mounted for free rotation. An upper link 24 is pivotally connected to the lower link 21 by a pin 23. The upper link 24 is held at one end of the opening 2 by a guide 25 so as to be movable up and down. Therefore, due to the rotation of the electric motor 19, the reduction gear 20
The rotary plate 17 is rotated strongly with high torque through
It is designed so that it can be forced up at the beginning of opening. The circuit of the electric motor 19 is constructed as shown in FIG.
6, the power supply circuit is cut off, and the power supply motor 1
9 can be stopped. A push button switch 27 for operating the power motor 19 is placed at a suitable location in the room, and when turned on, the power motor 19 can be driven and rotated.

Then, as shown in Fig. 5, the base 16 and the lower link 21
A pair of tension springs 28, 28 are stretched across the length of the tatami mat 3, and when the upper and lower links 24, 21 are pressed down on the tatami 3,
8 is balanced so that no rotational force is applied to the rotating plate 17 by the tension springs 28, 28. However, when the electric motor 19 rotates the rotary plate 17 in the direction of the arrow A in FIG. This makes it possible to supplement the capacity of the electric motor 19. Here, forced drive lifting means B
As shown in Fig. 1, is placed in the middle of the front edge of the opening 2, and by being placed at the front edge of the opening 2 in this way, the driving force that lifts the lid A at the beginning of opening is increased. The lid A can be lifted even if the lid is small, and the forced drive lifting means B
The driving force can be made relatively small.

In addition, the electric motor 19, the rotating plate 17, the lower link 2
1. The upper link 24, guide 25, etc. are collectively referred to as forced drive lifting means B for lifting the lid A, but such forced drive lifting means B can be modified in various ways.

[Effects of the invention] In summary, the present invention is arranged in close proximity to other adjacent flooring materials at the opening of the underfloor storage main body, so that the distance between the two and other flooring materials is small, and the device is placed in a closed state. Forced drive lifting means for lifting and moving the lid, which is rotated to open and close, and which is sometimes closed flush with other adjacent flooring materials, to a certain height at the beginning of opening by an electric drive, and the lid; It is equipped with a rotation link mechanism for rotating the lid to open and close it, and a rotation force assisting means for assisting the opening and closing operation of the lid, which is composed of a gas spring. Even if the lid is closed flush with the other flooring materials and is placed close to other flooring materials adjacent to it, so that the distance between the lid and other flooring materials is small, in other words, the appearance Even if the lid is placed in the opening so that it is difficult to see as a lid for opening and closing the top, the lid is lifted almost horizontally in the initial stage of lifting, so the edge of the lid strongly presses against the edge of the opening when opening and closing. The lid can be opened and closed without being scratched, and without damaging the edge of the lid and the edge of the opening during opening and closing, and further includes a forced drive lifting means. For example, even with heavy lids such as tatami mats, it is possible to easily open the lid, which requires a lot of effort, without using human power. The synergistic effect of the forced drive lifting means and the opening/closing operation force assisting means makes it even easier to open the lid from the beginning of opening to the upright position. There is an advantage. Also,
The opening/closing operation force assisting means are arranged on both sides of the opening, which serves as the rotational fulcrum of the lid, and the forced drive lifting means is arranged in the middle of the front edge of the opening, so that when the lid starts to open. The lid can be lifted even if the driving force to lift it is small,
There is an advantage that the driving force of the forced drive lifting means is relatively small, and that the lid can begin to open smoothly because the step of lifting substantially in parallel is performed by the forced drive lifting means rather than manually.
