It should be noted that parts that are functionally the same or equivalent to those in the previous figure are given the same reference numerals as in the previous figure with an alphanumeric letter "f", and redundant explanations are omitted.

As described above, in this invention, when the substrate of the earthquake-resistant metal fittings is placed on the upper furniture of the stacked furniture and the upper furniture is placed on the lower furniture, the downward engaging piece is attached to the lower furniture. is located on the outside of one side plate of the upper furniture so as to be able to engage with this side plate, and the inside and outside upward engaging pieces are located on the inside and outside of the side plate on the same side as the downward engaging piece of the upper furniture, respectively. Since it is positioned so that it can be engaged with the upper and lower furniture during an earthquake, by attaching it to the front, rear, left, and right sides of the stacked furniture, which are opposite to each other, It is possible to firmly prevent the relative lateral displacement of the upper furniture, thereby preventing the upper furniture from falling or toppling over the lower furniture, which has the effect of increasing safety.

Furthermore, even if the relative lateral displacement of the upper and lower furniture in stacked furniture can be firmly prevented as described above, the lateral displacement is caused by the downward engagement piece engaging the outside of the side plate of the lower furniture. , since the inner upward engaging piece and the outer upward engaging piece engage with the inner and outer side walls of the upper furniture, respectively, thereby preventing
When installing this earthquake-resistant metal fittings on stacked furniture,
Attach by placing the base plate of the earthquake-resistant metal fittings on the lower furniture, positioning the downward engaging piece on the outside of the side plate, and fitting the side plate of the upper furniture between the inner and outer upward engaging pieces. This has the effect of making it easier to install the earthquake-resistant metal fittings. Moreover, in the present invention, the inner upward engaging piece 12 and the outer upward engaging piece 1
1 is such that it is integrally secured to the upper furniture 4, so that the seismic metal fitting 5 has the advantage of being integrated with the upper furniture 4 in the above-mentioned attached state. For example, in the usage state shown in FIG. 14A, if the right end of the upper furniture 4 is about to lift up as shown in the figure due to lateral shaking caused by an earthquake, firstly, each of the upper furniture 4 is Since each of the downward engaging pieces 10 of the left and right seismic fittings 5 that are locked in place grips the lower furniture 3, it exhibits resistance against the above-mentioned uplift and prevents a large uplift. effective.

Secondly, even if lifting occurs in the above case, the downward engaging piece 10 of the earthquake-resistant metal fitting 5 that is integrally locked to the upper furniture 4 will still be in contact with the side surface of the lower furniture 3, as shown in the same figure. In contact with the upper furniture 4, it exhibits a large resistance against sideways sliding, and has the effect of preventing the upper furniture 4 from falling due to sideways sliding. Moreover, this effect is greatly exhibited because the above-mentioned uplift is small.

Thirdly, when the upper furniture 4 descends onto the lower furniture 3 after the above-mentioned floating, each engagement piece 10, 1
1 and 12 can return to their original positions (the positions shown in FIG. 3), and as a result, when another lateral sway is applied, the same effect as described above can be achieved.

As described above, the earthquake-resistant metal fitting of the present invention overcomes many of the drawbacks of the conventional earthquake-resistant metal fitting 40 shown in FIG. Under the same conditions, firstly, the upper furniture cannot show any resistance to the uplifting, so it will easily be lifted up even by a small lateral shake, and secondly, when the upper furniture lifts up, the lateral sliding force of the upper furniture will be reduced. If the force is applied, the metal fittings 40 will fall down as shown in the same figure, and will not exhibit much resistance against the upper furniture's sideways sliding, allowing the upper furniture to fall.Thirdly, in the above case, the upper furniture may accidentally fall. Even if the furniture does not fall, the upper furniture remains in its fallen state (without any force to prevent it from sliding sideways).
This is extremely useful as it can solve all of the numerous drawbacks of being left completely defenseless if the metal fitting 40 is stepped on and subjected to another lateral shake.

Furthermore, the present invention provides the first and second
While the downward engaging pieces 7 and 10 are made to hang straight downward, the first outer upward engaging piece 8 and the inner upward engaging piece 9, the second outer upward engaging piece 11 and Since it has a structure in which the inner upward engaging pieces 12 are each raised straight upwards, when furniture for general use is stacked, that is, in the case of lower furniture, the corners of the upper surfaces thereof are flat surfaces. On the other hand, when stacking pieces of furniture in which the outer and inner surfaces of the adjacent side panels of the lower part of the upper furniture are both flat surfaces, each of the four corners of the upper surface of the lower furniture Then, simply place the base plate 6 of each metal fitting 5 on top of each corner from directly above each corner, and then lower the upper furniture in a straight motion, i.e. With the simple operation of lowering the four corners of the lower part of the upper furniture from directly above the board 6 of each metal fitting 5 onto those boards 6, it can be moved to the left side against the back and forth shaking during an earthquake. The two earthquake-resistant metal fittings 5 installed and the two earthquake-resistant metal fittings placed on the right side can exert the above-mentioned effects 1 to 3, respectively, and can also be used to prevent vibrations in the left-right direction. In this case, the above-mentioned first to third
This method is useful in that it can highly reliably prevent stacked furniture from falling over due to an earthquake. Furthermore, although it is possible to firmly prevent the relative lateral displacement of the upper and lower furniture in stacked furniture as described above, the above-mentioned base plate, downward engaging piece, inner side and outer upward Since the engagement piece is formed by bending a single metal plate, it can be mass-produced at low cost using a press machine or the like.
