Abstract

PURPOSE: To support an object to be supported by slanting toward the wall by the difference in the thickness of two abutting parts of pads in contact with the front/rear and the top/bottom of the supported object at the corners. CONSTITUTION: An abutting part 2 of a pad P is in contact with the front of the supported object F. An abutting part 3 of the pad P is inserted between the supported object F and the floor B, and is in contact with the rear surface of the supported object F. An abutting part Z is inserted between the supported object F and the floor B. In this way, the supported object F is supported on the floor B by the same kind of the pad P in contact with the supported object F in a condition slightly curved toward the wall W. At the same time, the same kind of the pad is in contact with the upper corners of the rear surface of the supported object F, and is inserted between the supported object F and the wall W. Therefore, these pads P can be easily used for the existing furniture. Since the thickness of the abutting parts 2 and 3 of the pad P is different, the supported object can be supported with only one kind of the pad P in an antiseismic posture.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to a seismic isolation pad used for installing furniture or the like so that a held object, such as furniture, does not fall down due to vibration such as an earthquake.

[0002]

2. Description of the Related Art In general, the above-mentioned measures for preventing the furniture from falling over, as described in, for example, Japanese Utility Model Laid-Open No. 172543/1985, use a wheel carrier of a held object such as furniture. The structure is inclined so that the front part is higher than the rear part, and the object to be held is held in advance in a posture in which the object is warped to the wall surface side.

[0003]

However, in such a fall prevention measure for furniture or the like, it is necessary to previously equip the furniture with a specially-shaped base wheel.
It is difficult to easily adopt furniture that has already been installed. In addition, the function of absorbing and damping the vibration during an earthquake cannot be expected at all.

The present invention has been made in view of the above circumstances. The object of the present invention is that the object to be held such as furniture does not require any measures in advance, and it can be applied to furniture already installed. The purpose of this is to provide a seismic isolation pad that can be easily adapted and that can fully exhibit its fall prevention function. Another object of the present invention is to hold a held object such as furniture by using one kind or a plurality of pairs of pads,
It is to provide a seismic isolation pad that can exhibit a fall prevention function in the event of an earthquake.

[0005]

Therefore, in the present invention,
When a vibration is applied to the object to be held, the back of the object to be held is brought into contact with the corner of the object to be held and is inserted between the corner and the floor surface or between the corner and the wall surface. In a seismic isolation pad such as furniture that is supported on the wall surface side, in the pad main body, at least two front and rear and top and bottom contact portions of a held object have different thicknesses. Due to the difference in height, the pads having the same shape are used to incline the held object toward the wall and support it.

In this case, at least the portion of the pad body that comes into contact with the object to be held, the floor surface, and the wall surface is made of an elastic rubber material, and the abutting portion is
It is preferable to have supporting surfaces that are in contact with the object to be held and are substantially perpendicular to each other. Further, it is preferable that unevenness is formed on the held object, the floor surface, and the surface contacting the wall surface. Furthermore, it is advantageous that at least the contact portion on the thick side has a taper toward the tip side.

The pad body is made of a rubber-like material having a metal spring material embedded therein, and the spring material has a function of strengthening the elasticity of the contact portion. preferable. It is also possible to use a set of two types of pads each having a third contact portion that comes into contact with the side surface of the held object on the right side and the left side of the pad body. Furthermore, it is preferable that the pad body is formed of a non-repulsive rubber.

[0008]

In the seismic isolation pad of the present invention, the two thicknesses of the two contact portions of the pad body, which are in contact with at least the front and rear and the upper and lower sides of the corner of the object to be held, are different. By using the pads having the same shape, the held object can be tilted toward the wall surface side and supported.

[0009]

Embodiments of the present invention will be specifically described below with reference to the drawings. The seismic isolation pad P according to the present invention is basically in contact with a corner of a held object F such as furniture and is between the corner and the floor surface or between the corner and the wall surface. It is sandwiched so that the back of the held object is supported on the wall surface side when vibration is applied to the held object.

In this seismic isolation pad P, the pad body 1
Are different in the thickness of the two contact portions 2 and 3 contacting at least the front and rear and the top and bottom of the corner of the held object F, and the pads P having the same shape are used due to the difference in the thickness. The held object F is tilted toward the wall surface W and supported.

Particularly, in the embodiment shown in FIGS. 1 to 4,
The pad body 1 as a whole is L-shaped in a side view, and the entire pad body 1 (or at least the held object F
And a part which comes into contact with the floor surface B and the wall surface W) is made of an elastic rubber material, and the abutting parts 2 and 3 thereof are in contact with the object to be held F and are substantially orthogonal to each other. It has faces 2A and 3A.

Further, in this embodiment, for the purpose of strengthening the contact friction, the object F, the floor surface B, and the surface contacting the wall surface W are provided with irregular shapes, for example, convex portions 2B, 3B. ing. Further, for the purpose of improving the contactability with the object to be held, at least the contact portion 3 on the thick side has a taper toward the tip side.

In such a configuration, as shown in FIG.
The contact portion 2 is brought into contact with the front surface of the object to be held F, and the contact portion 3 is inserted between the object to be held F and the floor surface B so as to contact the object P to be held F and the pad P. The contact portion 3 is brought into contact with the rear surface of the object to be held F, the contact portion 2 is inserted between the object to be held F and the floor surface B, and the same pad P which is brought into contact with the object to be held F is used. The held object F is held on the floor surface B in a state of being slightly warped to the wall surface W side. At this time, as shown in the figure, the same pad P is brought into contact with the upper corner of the back surface of the held object F and inserted between the held object F and the wall surface W.

Therefore, the object to be held, such as furniture, does not require a prior structure such as a special shape of the pedestal, and the pad P can be easily applied to existing furniture. In this case, since the contact portions 2 and 3 of the pads P have different thicknesses, it is possible to hold the held object in a seismic posture by using one type of pad P. In addition, the pad body 1 as a whole (or at least for the contact portion),
Since it is made of rubber material, it can exhibit damping effect against vibration. In particular, it is more preferable to form the pad body 1 with a non-repulsive rubber because the damping effect against vibration is high.

Further, in order to apply it when the load of the object to be held F such as furniture is large, as shown in FIG. 5 and FIG. 6, the pad P is a pad body 1 made of the rubber material.
A spring material made of metal, for example, a leaf spring 4 or a coil spring 5 may be embedded in the interior of the above, and the elastic force of the contact portions 2 and 3 may be strengthened by the spring material.

In the embodiment shown in FIGS. 7 and 8, the seismic isolation pad has a third contact portion 6 that contacts the side surface of the object F to be held.
Are used as a set with two types of pads PA and PB provided on the right side and the left side of the pad body 1, respectively. This mode of use is shown in FIG. Other configurations and features
Since it is the same as the first embodiment, its explanation is omitted. In the figure, reference numeral 7 is a concave portion formed on the contact surface along with the aforementioned convex portion in an appropriate arrangement.

[0017]

As described in detail above, the present invention abuts against a corner of an object to be held, such as furniture, and between the corner and the floor surface,
Alternatively, in a seismic isolation pad such as furniture, which is inserted between the corner and the wall surface, and when the held object is vibrated, the back part of the held object is supported on the wall surface side, the pad body is At least the front and rear and the top and bottom of the corner of the object to be held are different in thickness, and due to the difference in the thickness, the pad having the same shape is used to hold the object to be held on the wall side. Since it is configured to be tilted to and supported, there is no need to take any measures in advance on the side of the object to be held such as furniture, it can be easily adapted to furniture already installed, and its fall prevention function is also sufficient. Can be demonstrated. In addition, a plurality of one type or a pair of pads can be used to hold an object to be held, such as furniture, and to exert a fall prevention function in the event of an earthquake.
