Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention mainly relates to the opening/closing structure of the lid plate of a large underfloor storage, and more specifically, the present invention relates to an opening/closing structure of a lid plate of a large underfloor storage compartment, and more specifically, to a lid plate that can be closed with increased safety near the end of closing. I am trying to do this. .

[Prior art 1] Conventionally, in a large underfloor storage, the lid plate also had a heavy opening, and the lid closed with force especially when the lid was closed.

[Problems to be Solved by the Invention] However, when such a heavy lid plate is closed forcefully at the end of its closing, there is a problem in that hands, feet, etc. may become stuffed.

The present invention was made in view of such problems,
The purpose of this is to create a safe opening/closing structure for the underfloor storage lid plate that can be opened and closed lightly and easily, while also being able to close slowly at the end of closing, preventing fingers from getting jammed, etc. It is about providing.

[Means for Solving the Problem 1] The opening/closing structure of the lid plate of the underfloor storage according to the present invention includes a gas spring 1 containing high-pressure gas to support the load of the lid plate 3 and lightly open/close the lid plate 3. , a damper sill 2 containing a buffer fluid and exerting a strong damping effect with the built-in buffer fluid in the closed end region of the cover plate 3.

[Function 1] As described above, the gas spring 1 houses high-pressure gas to support the load of the lid plate 3 and lightly open and close the lid plate 3,
The load of the cover plate 3 is supported by the gas spring 1 by providing a gunper cylinder 2 which stores a buffer fluid and exhibits a strong buffering effect with the buffer fluid at the inner point in the closed end area of the cover plate 3. While opening and closing the heavy lid plate 3 lightly, the gunbar seal 2 exerts a strong buffering effect, especially in the closed end area of the heavy lid plate 3, and the This is to prevent stuffing etc. from occurring.

[Example 1 Embodiments of the present invention will be described in detail below based on the drawings.

At the end of the lid plate 3 on the rotation center side, which is opened and closed by the opening 22 of the underfloor storage main body 21, a support 10 is attached to the lid plate 3 side and a support is attached to the floor r storage main body 21 side. A first link 4 is constructed across the opening of the box 11 by pivotally connecting both ends thereof. The first link 4 extends beyond the fixed pivot connection point Q on the support box 11 side. One end of the second link 5, which is longer than the first link 4, is pivotally connected to the cover plate 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 formed in the underfloor storage main body 21 so that the row 21 can slide freely into a substantially horizontally long elongated hole 6.
They are freely movable and play together via 2.

A connecting link for causing the loose end 7 of the second link 5 to run toward the rotation center side of the elongated hole 6 as the first link 4 swings upright about the fixed pivot connection point Q. 8 first
The link 4 and the second link 5 are rotatably connected.

However, as described above, the end of the link 1217, which is longer than the first link 4, is slidably slid into the elongated hole 6 formed on the side of the underfloor storage main body 21 in a substantially horizontal direction. A connecting link 8 is connected to the first link 4 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. The lid plate 3 is closed by being pivotally connected to the second link 5 open.
4(a)(b)(c) and 5.
As shown in the figure, as the tI%1 link 4 rotates upright, the loose end 7 of the second link 5, which is longer than the first link 4, moves along the elongated hole 6 toward the center of rotation. The movement causes the second link 5 to rise and rotate, thereby lifting the cover plate 3 approximately in parallel at the initial stage of lifting, thereby preventing the edge of the cover plate 3 from being strongly rubbed against the edge of the opening 2. This avoids damage to the cover plate 3 during opening and closing.

A gas spring 1 is interposed between the support body 10 of the lid plate 3 and the support box 11 of the underfloor storage main body 21, so that the lid plate 3 can be lifted and rotated with a light force. The opening/closing rotational position can be maintained at the same time. Such a gas spring 1 seals high-pressure gas in a Schilling-tube 14 and moves a piston (not shown) 1.
By inserting the piston, connecting the piston rod 15 to the piston, and opening and closing the valve formed on the piston, the gas pressure in the gas chamber on the bottom side pushes up the piston rod 15 and lightly lifts the cover plate 3. The piston rod 15 is inserted into the shilling tube 14 by the pushing down force, and the cover plate 3 can be pushed down lightly. Gas spring like this 1
Use well-known ones. The valve operation of the piston is preferably linked to the lifting and pressing down of the cover plate 3.

As shown in FIG. 6, the elongated hole 6 is curved into a substantially arc shape so as to be close to the center of rotation of the cover plate 3.
By curving the elongated hole 6 into an arc shape in this manner, the end of the cover plate 3 on the rotation center side can swing further away from the wall or the like.

By the way, when the lid plate 3 is in the open position, the first link 4 and the connecting link 8 are in a substantially horizontal position, and as the lid @ 3 is placed in the open position! The @1 link 4 and the connecting link 8 are bent and swung in a reverse C shape at the pivot connection point P, and the first link 4 is equipped with a leaf spring as shown in FIG. 17 is installed, and this leaf spring 17
When the cover plate 3 is in the closed position! It is designed so that it can be brought into elastic contact with the lower surface of #2 link 5. As the leaf spring 17 comes into elastic contact with the lower surface of the second link 5, the pivot connection point P between the i-link 4 and the connecting link 8, which is in a substantially horizontal position when the lid plate 3 is in the closed position, is moved downward by the spring. This allows it to be biased by force.

However, at the beginning of opening when opening the cover plate 3,
Applying a biasing force downward at the pivot connection point P between the first link 4 and the connecting link 8, which are in a substantially horizontal position, that is, in the bending direction of the first link 4 and the connecting link 8, By applying a biasing force in the opening direction in the closed state in this way, the first link 4 and the connecting link 8, which are in a substantially horizontal direction, will not be pushed against each other during the opening operation, and the opening operation will be performed. It can be done smoothly and easily.

A damper cylinder 2 is installed between the support body 10 and the support box 11, which contains a buffer fluid and exerts a strong damping effect with the built-in buffer fluid in the closed end region of the cover plate 3.

As an example of the damper cylinder 2, as shown in FIG.
are connected, an air hole 26 is formed on the bottom side of the cylinder tube 23, and the lid plate 3 is closed to contract the damper cylinder 2 from the extended state in which the piston rod 25 is protruded from the cylinder tube 23. In the early and middle stages of closing, the internal air escapes to the outside from the air hole 26 and is compressed, so the damper cylinder 2 contracts at a high speed, and the cover plate 3
In the closed end region of , the internal air is compressed to the limit, and the damper cylinder 2 contracts at a slow speed.
In the closing end region of the lid plate 3, the lid plate 3 is gently closed to prevent finger jamming or the like from occurring.

FIG. 10 shows another embodiment of the damper cylinder 2, in which oil 27 as a buffer fluid is put in the bottom side of the cylinder tube 23, and air is filled in the other parts. Then, oriais 28 is formed on the piston rod 25,
Further, a resistance valve 30 having a hole 29 smaller than the orifice 28 is provided so as to be swingable. In the early and middle stages of closing the cover plate 3, air moves from the hole 29 and orifice 28 of the resistance valve 30 into the chamber on the piston rod 25 side.
In the closing end region, the oil 27, which has a higher viscosity than air, moves from the hole 29 and orifice 28 of the resistance valve 30 at a slow speed, fully exerts its buffering effect, and The opening speed in the closing end region of No. 3 is made sufficiently slow to prevent fingers from jamming or the like. In order to open the cover plate 3, the resistance valve 30 is connected to the orifice 28.
The oil 27 and air move away from each other with less resistance.

Effects of the Invention 1 In short, the present invention has a gas spring containing high-pressure gas to support the load of the cover plate and easily close the cover plate by 1 m, and a gas spring containing a buffer fluid to close the cover plate using ν1. Since the terminal area is equipped with a damper cylinder that exerts a strong buffering effect with built-in buffer fluid, the load of the lid plate is supported by the gas spring and the heavy lid plate can be opened and closed easily. Especially in the closed end area of the lid plate,
The advantage is that the damper cylinder exerts a strong buffering effect, prevents the closing path nA of the heavy cover plate from being closed forcefully, prevents fingers from getting jammed, and improves safety. be.
