FIG. 13 is a perspective view of a base according to a fifth embodiment of the present invention.

A first embodiment of the present invention will be described below with reference to Figures 1 to 3. This first embodiment shows an example in which the present invention is applied to a Buddhist altar.
First, as shown in Fig. 1, the Buddhist altar 1 according to the first embodiment has an altar main body 3. The altar main body 3 is fixed on a pedestal 5. Upper and lower Kannon doors 4a, 4b and 6a, 6b are installed on the front side of the altar main body 3 so as to be freely opened and closed. The upper Kannon doors 4a, 4b house the principal image, memorial tablets, etc. The lower Kannon doors 6a, 6b house incense sticks and other Buddhist implements.

As shown in FIG. 2, a tip-prevention member storage section 7 is provided inside the base 5. Tip-prevention member guide rails 9, 9 are provided on both the left and right sides of the tip-prevention member storage section 7 in FIG. 2. A tip-prevention member 11 is provided within the tip-prevention member storage section 7 so as to be movable along the tip-prevention member guide rails 9, 9.

A vibration-sensing operation fitting 13 is installed at the back (lower side in FIG. 2) of the tip-over prevention member housing 7. The vibration-sensing operation fitting 13 has a fitting body 15 that is fixed to the base 5. The vibration-sensing operation fitting 13 also has an operating part 17, which is attached so as to be movable relative to the fitting body 15. Operating part side guide rails 19, 19 are installed on both the left and right sides of the operating part 17 in FIG. 2. As shown in FIG. 3, the operating part side guide rail 19 has a substantially U-shaped cross section, and long holes 21, 21 are formed on both sides (both vertical sides in FIG. 3) that extend in the left and right direction in FIG. 2.

The operating part 17 and the metal fitting body 15 are connected by links 23, 23. The link 23 has a link arm 25. The base end side of the link arm 25 is rotatably connected to the metal fitting body 15 via a rotation shaft 26. A link shaft 27 is rotatably installed at the tip side of the link arm 25, and both ends of the link shaft 27 are movably engaged with the long holes 21, 21 of the operating part side guide rail 19. In other words, the base end side of the link arms 25, 25 is rotatable relative to the metal fitting body 15, and the tip side of the link arms 25, 25 is rotatable and slidable relative to the operating part 17, and the operating part 17 is configured to be detachable from the metal fitting body 15.

In this embodiment, the operating part 17 and the tip-prevention member 11 are in a non-connected state. By pushing the tip-prevention member 11 into the tip-prevention member housing part 7, the operating part 17 is brought close to the metal fitting body 15, and by moving the operating part 17 away from the metal fitting body 15 by a mechanism described later, the tip-prevention member 11 is caused to protrude forward from within the tip-prevention member housing part 7. In addition, the tip-prevention member 11 can be manually pulled forward by any amount regardless of the operation of the vibration-sensing operation metal fitting 13.

Coil springs 29, 29 are installed as elastic means on the base end side of the link arms 25, 25. The coil springs 29 are passed through by the pivot shaft 26, one end of the coil spring 29 is in contact with the inner surface of the metal fitting body 15, and the other end of the coil spring 29 is in contact with the link arm 25. The operating unit 17 is biased in a direction away from the metal fitting body 15 by the coil springs 29, 29.

The vibration sensing operation fitting 13 has a holding means 31. The holding means 31 has a pendulum arm 33. The pendulum arm 33 is rotatably installed on the fitting body 15 via a rotation shaft 34. The pendulum arm 33 is longer from the center of rotation to the other end side (right side in FIG. 2) than to one end side (left side in FIG. 2). A balance weight 35 is installed on the other end side of the pendulum arm 33. A screw 39 that passes through a long hole 37 formed in the pendulum arm 33 is screwed into the balance weight 35, and the balance weight 35 is fixed at any position along the long hole 37. The pendulum arm 33 is made of a magnetic material, for example, iron.

The holding means 31 also has a magnet 41. The magnet 41 is installed on the operating part 17, and is attracted to one end side (left side in FIG. 2) of the pendulum arm 33, thereby holding the operating part 17 against the elastic force of the coil springs 29, 29 on the metal fitting main body 15 side.

A coil spring 43 is also installed on the pivot shaft 34. One end of the coil spring 43 is in contact with the metal fitting body 15, and the other end of the coil spring 43 is in contact with the pendulum arm 33. The pendulum arm 33 is biased by the coil spring 43 to rotate so that the other end where the balance weight 35 is installed moves toward the metal fitting body 15.

By adjusting the strength of the coil spring 43 and the position of the balance weight 35, the degree of vibration required to rotate the pendulum arm 33 and release the attraction between the pendulum arm 33 and the magnet 41, i.e., the sensitivity of vibration detection, can be set.

The operation of the above configuration will now be described.
First, the standby state will be described. In this state, the tip-prevention member 11 is manually pushed into the tip-prevention member housing portion 7. This causes the operating portion 17 to be biased toward the metal fitting body 15, and the pendulum arm 33 and the magnet 41 are attracted to each other, thereby maintaining this state.
In this state, if an earthquake occurs, the vibration causes the pendulum arm 33 to rotate against the biasing force of the coil spring 43, and the attraction between the pendulum arm 33 and the magnet 41 is released. Then, the elastic force of the coil springs 29, 29 causes the operating part 17 to move away from the metal fitting main body 15, whereby the tip-prevention member 11 is pushed outward and forward from within the tip-prevention member accommodating portion 7.
This prevents the Buddhist altar 1 from tipping forward.

Moreover, regardless of the operating state of the vibration sensing operation fitting 13, the tip-over prevention member 11 can be manually pulled out forward by a predetermined distance.

As described above, according to the first embodiment, the following effects can be obtained.
First, the occurrence of an earthquake can be detected with high accuracy, and the anti-toppling function can be reliably performed. This is because the occurrence of an earthquake is detected with high accuracy by the vibration sensor operating fitting 13, and the anti-toppling member 11 is automatically pushed out of the base 5.
Furthermore, since the vibration sensing operation fitting 13 is constructed by utilizing the attraction between the magnet 41 and the pendulum arm 33, the construction is simple and the fitting can reliably detect the occurrence of an earthquake and exhibit a function of preventing the fitting from falling over.
In addition, the sensitivity for detecting earthquake vibrations can be adjusted as desired by adjusting the strength of the coil spring 43 and the position of the balance weight 35.
Furthermore, since the vibration detection operation fitting 13 and the tip-prevention member 11 are installed in a non-connected state, the tip-prevention member 11 can be manually pulled out to any desired extent regardless of the state of the vibration detection operation fitting 13.

Next, a second embodiment of the present invention will be described with reference to FIG. 4. In this second embodiment, a vibration detection operation fitting 101 having a different configuration from that of the first embodiment is used. The vibration detection operation fitting 101 is provided with a holding means 103.

The holding means 103 has a configuration substantially similar to that of the holding means in the first embodiment, but differs in that it uses a pendulum arm 105 and a strike 107. The pendulum arm 105 has an engagement portion 109 formed on one end side (the right side in FIG. 4 ). Moreover, the strike 107 is provided on the operating portion 17 instead of a magnet. The strike 107 is engaged with the engagement portion 109, thereby holding the operating portion 17 on the metal fitting main body 15 side against the elastic force of the coil springs 29, 29.
Other configurations are the same as those in the first embodiment, and the same parts in the drawings are indicated by the same reference numerals and their explanation is omitted.

The above configuration can achieve the same effects and advantages as the Buddhist altar 1 in the first embodiment.

Next, a third embodiment of the present invention will be described with reference to FIGS.
In the first and second embodiments, the anti-tip function is achieved by using anti-tip members, but in this third embodiment, the anti-tip function is achieved by using only the vibration detection operating fittings, without using any anti-tip members.
That is, a vibration detection operation fitting 13 is installed on the front surface of the base 5. This vibration detection operation fitting 13 is the same as the vibration detection operation fitting in the case of the first embodiment. Also, the operation part 17 itself functions as a tip-over prevention member.
Other configurations are the same as those in the first embodiment, and the same parts in the drawings are indicated by the same reference numerals and their explanation is omitted.

According to the above-mentioned configuration, during standby, the pendulum arm 33 and the magnet 41 are attracted to each other, so that the operating portion 17 is held on the side of the metal fitting body 15 .
At this time, if an earthquake occurs, the vibration causes the pendulum arm 33 to rotate, and the attraction between the pendulum arm 33 and the magnet 41 is released. Then, the elastic force of the coil springs 29, 29 pushes the operating portion 17 forward.
This prevents the Buddhist altar 1 from tipping forward.

Therefore, it is possible to achieve the same functions and effects as the Buddhist altar 1 in the first embodiment.
Furthermore, since no tip-over prevention member is used, the structure can be made simpler.

Next, a fourth embodiment of the present invention will be described with reference to FIG.
Like the third embodiment, the fourth embodiment is also configured to achieve the anti-toppling function by using only the vibration detection operation fittings without using any anti-toppling members.

In the fourth embodiment, a vibration detection metal fitting 101 is installed on the front surface of the base 5. This vibration detection metal fitting 101 is the same as the vibration detection metal fitting in the second embodiment. In addition, the operating portion 17 itself functions as a tip-over prevention member.
Other configurations are the same as those of the second embodiment, and the same parts in the drawings are indicated by the same reference numerals and their explanation is omitted.

According to the above configuration, during standby, the strike 107 and the engaging portion 109 are engaged with each other, thereby holding the operating portion 17 on the metal fitting main body 15 side against the elastic force of the coil springs 29, 29.
At this time, if an earthquake occurs, the vibration causes the pendulum arm 33 to rotate, and the engagement between the strike 107 and the engagement portion 109 is released. Then, the elastic force of the coil springs 29, 29 pushes the operating portion 17 forward.
This prevents the Buddhist altar 1 from tipping forward.

Therefore, it is possible to achieve the same effects and advantages as the furniture 1 with tip-over prevention function in the second embodiment.

Next, a fifth embodiment of the present invention will be described with reference to Fig. 8. The furniture with a tip-over prevention function according to the fifth embodiment has a base 401, which has the same structure as the base of the Buddhist altar according to the first embodiment. Various pieces of furniture (not shown) are placed on the base 401.
Other configurations are the same as those in the first embodiment, and the same parts in the drawings are indicated by the same reference numerals and their explanation is omitted.

According to the above configuration, it is possible to achieve the same functions and effects as those of the first embodiment.
Furthermore, by installing it under various existing furniture, it is possible to add a tip-over prevention function to the furniture.

The present invention is not limited to the first to fifth embodiments.
First, in the first and fifth embodiments, the operating portion of the vibration sensing operation fitting and the tip-over prevention member are not connected to each other, but they may be connected to each other.
In addition, in the first to fifth embodiments, a Buddhist altar and a pedestal were given as examples of furniture with a tip-over prevention function, but the present invention is not limited to these and can be applied to chests of drawers, chests, desks, and various other furniture.
In addition, in the first to fifth embodiments, an example has been described in which the anti-tip member or operating part protrudes forward of the furniture to prevent it from tipping forward, but this is not limited to this, and the anti-tip member or operating part may be configured to prevent tipping in various directions, such as protruding the anti-tip member or operating part rearward, protruding to the left, protruding to the right, protruding the anti-tip member or operating part in the front-to-back direction, protruding the anti-tip member or operating part in the left-to-right direction, or protruding the anti-tip member or operating part in the front-to-back and left-to-right directions.
Additionally, the configurations shown in the drawings are merely examples.

The present invention relates to furniture with a fall prevention function that prevents furniture from falling over due to an earthquake, and in particular to furniture that is designed to detect the occurrence of an earthquake with high accuracy and reliably perform a fall prevention function, and is suitable for preventing Buddhist altars and the like from falling over due to an earthquake.
