Abstract

Disclosed is a furniture impact mitigation device that reduces the shaking and impact of furniture caused by an earthquake, and protects articles in the furniture. An air outlet at the tip of a small air inlet has a small-diameter hole, and a piston shaft for pushing out air is inserted into a lot shaft, and a coil spring is passed through the air pressure action and air negative pressure action. The air damper, which is characterized by utilizing the above action, is attached and connected between the upper part of the furniture and the wall of the furniture installation part using a flexible metal fitting.

Description

The present invention relates to a furniture impact mitigation device using an air damper and an interior lighting device that is interlocked.

A metal fitting for fixing furniture and a wall for preventing furniture collapse due to an earthquake is conventionally known.

However, even if the furniture itself does not collapse, a tableware bowl that stores a lot of broken objects collapses the items in the furniture, and further breaks the front glass door of the furniture and scatters on the floor. Such damage is not exempted.
Also, if a big earthquake occurs at night and a power failure occurs, the house will be completely dark. For this reason, it is very difficult and difficult to move in the middle of searching for unknown damage.
There were drawbacks such as inability to solve such problems.

The present invention is an air damper that connects furniture and a wall with an air damper instead of a fixing bracket. A momentary air spring action acts on both pushing and stretching of the rotator. Furthermore, a built-in coil spring assists this function.

In addition, the expansion and contraction of the air damper, which is a furniture shock mitigation device, is changed to a rotational motion by a screw shaft built in the robot.
This turns the small generator to charge the battery with the generated electricity. This is continued to illuminate the interior of the house with the light-emitting diode illuminator even after the earthquake.
This solves the above problem.

The basic form of the air damper of the present invention is that a piston valve (2) is attached to the tip of the telescopic rod (1) as shown in FIG.
When the lot shrinks, the air in the damper goes out from the air outlet (3), but when the lot shrinks rapidly due to the small size of the air outlet hole, the inside air is compressed for a moment, resulting in a spring effect.
On the other hand, when the lot is pulled out of the damper rapidly, the air outlet hole is small, so the air in the damper becomes a negative pressure momentarily and puts a load on the extension of the lot. Further, the coil spring (4) is contracted to increase the load of the expansion of the lot.
"FIG. 2" is a side view in which an air damper is attached to furniture.
The furniture moves once (A) due to the expansion of the damper knot at the time of a large earthquake, but the air in the air damper becomes negative pressure and further the contraction force of the coil spring is added to suppress the expansion of the damper knot for a moment. (B) The furniture bottom also moves slightly.
The next moment (C) the furniture moved forward moves violently in the direction of the arrow and collides with the wall. This can absorb the impact greatly by the compression effect of the air in the air damper.

Next, "FIG. 3" shows an internal view of the lighting device built in the air damper and capable of interlocking.
A motor (6) charging base (7) storage battery (8) and a gear (9) for increasing the rotational speed of the generator are incorporated in the front part of the air damper basic body (5), and a power switch (10 ).
The luminaire is separate from the main body and is extended with an extension cord.
Moreover, what is shown in FIG. 4 is a function for turning the generator by converting the expansion and contraction of the damper nut into a rotational motion.
The rotating shaft (11) has a loose pitch rotating groove. The rotation guide ring (12) is provided with a projection having the same pitch as the rotation shaft (11) and the same shape as the groove on the inner side of the ring.
The rotating shaft (11) is accommodated in the guide ring (12) with such a state that the protrusion line meshes with the groove of the rotating shaft (11).
Furthermore, this rotation guide ring (12) is connected to the tip of the air damper lot.
As a result, the horizontal movement of the rotor becomes the rotation of the rotary shaft (11) as it is, and the gears are turned to operate the generator.

Effect of device

The furniture impact mitigation device capable of generating and illuminating according to the present invention can not only prevent furniture collapse due to shaking of an earthquake, but also can protect articles in the furniture greatly.
Furthermore, the danger and anxiety caused by a power failure due to a nighttime earthquake will be solved by a lighting device that operates by shaking the earthquake.

It is an internal view of an air damper. Attaching an air damper to the furniture An illustration when the furniture moves during an earthquake and a figure when a lighting fixture is attached to the top of the furniture It is an internal view of the electric power generation and electrical storage apparatus which is a furniture impact mitigation apparatus, and is built in and can be interlocked with an air damper. It is an apparatus figure which changes the horizontal movement of a damper lot into rotation. The air damper mounting bracket is represented by a plan view and a side view. It can be rotated up and down, and the damper-rotation connecting portion rotates in the horizontal direction. The movement of the furniture during a tremor changes drastically back and forth, left and right, and up and down, and an excessive force is applied to the air damper to prevent damage.
