Description
【０００１】[0001]
本考案は、地震による震動によって家具類が転倒することを防止する家具類の 耐震用支持装置に関する。 The present invention relates to a furniture earthquake-proof support device that prevents furniture from falling due to a vibration caused by an earthquake.
【０００２】[0002]
従来のこの種の家具類の耐震用支持装置は、例えば、実公昭６３−１２７号公 報に記載されている構造が知られている。この従来の支持装置は、支柱の上下端 に板ばねを介して支承部をそれぞれ取り付け、この下部支承部を家具類の上面に 載置するとともに上部支承部を天井面に当接し、板ばねの弾力で上下支承部を天 井面と家具類の上面に圧接させて震動などにより家具が倒れることを防止する構 造が採られている。 As a conventional seismic support device for this type of furniture, for example, a structure described in Japanese Utility Model Publication No. 63-127 is known. In this conventional supporting device, bearings are attached to the upper and lower ends of a column via leaf springs, respectively, and the lower bearings are placed on the upper surface of furniture and the upper bearings are brought into contact with the ceiling surface. A structure is adopted in which the upper and lower bearings are elastically pressed against the ceiling surface and the upper surface of the furniture to prevent the furniture from falling down due to a vibration or the like.
【０００３】[0003]
上記従来の構造の家具類の耐震用支持装置では、家具類と天井面との間に支持 装置を装着するのみで、支持装置による取付け痕跡が家具類に付くことがなく、 容易に家具類の転倒を防止することができる利点を有している反面、上記従来の 装置では、上下の板ばねの弾性変形量が少なく、家具類の上下震動の振幅が大き いと、家具類の上面と天井面との間で支持装置の圧接が解かれて支柱が外れるお それがある問題を有していた。 In the above-described conventional support device for earthquake resistance of furniture, only mounting the support device between the furniture and the ceiling surface does not leave a trace of attachment by the support device on the furniture, and the furniture can be easily attached. On the other hand, it has the advantage of preventing falls, but in the above conventional device, the amount of elastic deformation of the upper and lower leaf springs is small, and the amplitude of vertical vibration of furniture is large. There was a problem in that the support device was unpressurized between and the pillars might come off.
【０００４】 本考案は上記問題点に鑑みなされたもので、地震時の上下震動の振幅が大きい ときに、震動による歪みで家具類の上面と天井面との間の寸法が大きく変化して も、上下部支柱がその歪み寸法の変化を吸収して支柱が外れることのない家具類 の耐震用支持装置を提供するものである。The present invention has been made in view of the above problems, and when the amplitude of vertical vibration during an earthquake is large, even if the dimension between the top surface and the ceiling surface of furniture changes greatly due to the distortion due to the vibration. The purpose of the present invention is to provide a seismic support device for furniture in which the upper and lower columns do not absorb the change in strain dimension and the columns do not come off.

【００１７】 また、21はねじ杆で前記上部支柱15に嵌挿され、このねじ杆21の上端は前記上 部支承部16の基板17に取付けられ、このねじ杆21の前記上部支柱15より突出した 下端部にはこのねじ杆21に進退自在に締め付けナット22が螺合されている。そし て、この締め付けナット22の下部には前記下部支柱１の上端部に着脱自在でかつ 進退自在に嵌合できる外径の接続部23が形成され、この締め付けナット22の上部 には、摺動支柱24の下端部を嵌合できる外径の係合段部25が形成されている。Reference numeral 21 is a screw rod that is fitted and inserted into the upper support column 15. The upper end of the screw rod 21 is attached to the base plate 17 of the upper support portion 16 and protrudes from the upper support column 15 of the screw rod 21. At the lower end, a tightening nut 22 is screwed onto the screw rod 21 so as to move back and forth.

【００２０】 次に、この実施例の作用を説明する。Next, the operation of this embodiment will be described.
【００２１】 図４に示すように、下部支柱１に上部支柱15を接続した状態で、この下部支柱 １の下部支承部２を家具類29の上面に載置する。このとき、下部支柱１の下部支 承部２は前側への突出寸法より後側への突出寸法が短くなっているため、震動に 対して歪みが比較的に少ない壁際に設置できる。また、上部支柱15の上部支承部 16を天井面27に直接または天井面27との間に介在させた補強板28の下側に位置さ せる。この状態で締め付けナット22を回動させて締め付けナット22をねじ杆21の 下側に移動させると、上部支柱15は上昇されて上部支承部16は天井面27または補 強板28に当接され、さらに、締め付けナット22を下降させると、スプリング９が 弾力に抗して圧縮され、両支柱１，15の支承部２，16が家具類29の上面と天井面 27または補強板28の下面に圧接される。As shown in FIG. 4, with the upper column 15 connected to the lower column 1, the lower support portion 2 of the lower column 1 is placed on the upper surface of the furniture 29. At this time, since the lower support portion 2 of the lower strut 1 has a shorter rearward projecting dimension than a frontward projecting dimension, the lower supporting section 2 can be installed on a wall where distortion is relatively small against vibration. Further, the upper support portion 16 of the upper column 15 is located directly on the ceiling surface 27 or below the reinforcing plate 28 interposed between the ceiling surface 27 and the ceiling surface 27. In this state, when the tightening nut 22 is rotated to move the tightening nut 22 to the lower side of the screw rod 21, the upper support column 15 is lifted and the upper support portion 16 is brought into contact with the ceiling surface 27 or the reinforcing plate 28. , When the tightening nut 22 is further lowered, the spring 9 is compressed against the elastic force, and the support portions 2 and 16 of the columns 1 and 15 are placed on the upper surface of the furniture 29 and the ceiling surface 27 or the lower surface of the reinforcing plate 28. Pressed.
【００２２】 また、この締め付けナット22をねじ杆21の下側に移動させて上部支柱15を上昇 させる際に、摺動支柱24の上端部は拡径され上部支柱15の内周面に略接触する外 径を有する拡径案内部26に案内され、摺動支柱24は傾斜されることがないので、 上部支柱15は昇降される。Further, when the tightening nut 22 is moved to the lower side of the screw rod 21 to raise the upper strut 15, the upper end of the sliding strut 24 is expanded and substantially contacts the inner peripheral surface of the upper strut 15. Since the sliding support column 24 is not tilted by being guided by the enlarged diameter guide portion 26 having the outer diameter, the upper support column 15 is moved up and down.
【００２３】 そして、前記下部支柱１の上端部に前記締め付けナット22に螺合したねじ杆21 を上部支承部16を介して取付けた上部支柱15が下部支柱１に接続される。この状 態で、上部支柱15と下部支柱１との長さを伸張させたときに、下部支柱１と上部 支柱15との間に位置する摺動支柱24によりねじ杆21が露出されることがなく、外 観性を損なうこともない。Then, an upper strut 15 having a threaded rod 21 screwed onto the tightening nut 22 attached to the upper end of the lower strut 1 via an upper bearing 16 is connected to the lower strut 1. In this state, when the length of the upper strut 15 and the lower strut 1 is extended, the screw rod 21 may be exposed by the sliding strut 24 located between the lower strut 1 and the upper strut 15. There is no loss of appearance.
【００２４】 この状態で、地震などの震動が生じたとき、建造物の震動による歪みで家具類 29が上下動で、上部支柱15の支承部16と天井面27または補強板28の下面との間の 寸法が拡がっても、スプリング９が弾力で伸張して、両支柱１，15の支承部２， 16が家具類29の上面と天井面27または補強板28の下面に圧接した状態に保持され 、上下支柱１，15が家具類29の上面と天井面27または補強板28とから外れて倒れ ることなく、家具類29を支え、家具類29の転倒を防止する。In this state, when a vibration such as an earthquake occurs, the furniture 29 moves up and down due to the distortion due to the vibration of the building, and the supporting portion 16 of the upper pillar 15 and the ceiling surface 27 or the lower surface of the reinforcing plate 28 are separated from each other. Even if the space between them expands, the spring 9 stretches elastically, and the support portions 2 and 16 of the columns 1 and 15 are held in pressure contact with the upper surface of the furniture 29 and the ceiling surface 27 or the lower surface of the reinforcing plate 28. Therefore, the upper and lower columns 1, 15 support the furniture 29 without falling off from the upper surface of the furniture 29 and the ceiling surface 27 or the reinforcing plate 28, and prevent the furniture 29 from falling.
【００２５】 さらに、下部支柱１の下部支承部２および上部支柱15の上部支承部16は前側へ の突出寸法より後側への突出寸法が短く、建造物の震動による歪みの少ない壁際 に設置でき、家具類29の転倒防止効果を確実にできる。Further, the lower bearing portion 2 of the lower strut 1 and the upper bearing portion 16 of the upper strut 15 have a shorter projecting dimension to the rear side than a projecting dimension to the front side, and thus can be installed on a wall which is less distorted by vibration of a building. The effect of preventing the furniture 29 from falling can be ensured.

By placing it between the upper support and the upper support, the tightening nut pushes the upper support upward with the biasing force of the coiled spring on the lower support, and the upper support of the upper support is pressed against the ceiling surface. Even if the distance between the top surface of the furniture and the ceiling surface changes significantly due to the distortion caused by the building's vibration caused by an earthquake or the like, the coiled spring causes a large amount of displacement. Even if there is a large change in the distance between the surface and the furniture, it is possible to prevent the furniture from falling down by pressing the furniture from the top.
