Description
本発明は、地震発生時の揺れによる棚からの物品の落下を防止する装置に関する。 TECHNICAL FIELD The present invention relates to a device for preventing articles from falling from shelves due to shaking during an earthquake.
従来、地震発生時の揺れによりスーパー、商店の商品棚から飲料の瓶が床に落下して割れてしまい、復旧の手間及び、多額の損失が問題となっていた。
主な対策として、地震発生を検知次第、棚の前面に棒状のバー等を展開して物品が棚から落ちない構造にしているものが見受けられる。In the past, beverage bottles fell from shelves in supermarkets and stores to the floor and broke due to the shaking caused by earthquakes.
As a main countermeasure, there are cases where, as soon as an earthquake is detected, a rod-shaped bar or the like is deployed in front of the shelf to prevent articles from falling off the shelf.
主なものとして、装置内に設置された振り子が地震を検知することで、落下防止バーのロックを解除し、これが上昇することで棚に設置された物品の落下を防止する（特許文献１）、地震を検知することで棚の上部に設置した振り子が振れ、ロックを解除することで、全段のバーを一体構成にした枠体が落下することで、全段棚の開口中央部にバーを展開して物品の落下を防止する（特許文献２）、物品を設置する棚板を棚枠からワイヤ状のもので吊るすことで地震の揺れの影響を受け難くして物品の落下を防止する（特許文献３）、地震の揺れを検知すると、棚に設置された物品の上部にある袋状弾性体に流体を充填することで物品を上から押さえつけ、地震の揺れから物品の移動を防ぐため、棚からの物品の落下はもちろん、個々の物品の接触による損傷を防ぐ（特許文献４）が開示されている。 Mainly, when a pendulum installed in the device detects an earthquake, it unlocks a fall prevention bar, which rises to prevent articles placed on shelves from falling (Patent Document 1). When an earthquake is detected, the pendulum installed at the top of the shelf swings, and when the lock is released, the frame that integrates the bars on all levels falls, and a bar is placed in the center of the opening of all the shelves. (Patent Document 2), and by suspending the shelf board on which the article is installed from the shelf frame with a wire-like object, it is difficult to be affected by the shaking of an earthquake and prevents the article from falling. (Patent Document 3), when an earthquake shake is detected, a fluid is filled in a bag-shaped elastic body on the upper part of the article installed on the shelf to hold down the article from above and prevent the movement of the article from the earthquake shake. , preventing damage due to contact of individual articles as well as dropping of articles from shelves (Patent Document 4).
しかし特許文献１、２は、物品の棚からの落下は防げるものの、地震の揺れに伴う物品の移動への拘束がないため個々の物品の接触による損傷の恐れがあり、物品によっては転倒によって落下防止バーの下をすり抜ける場合があるという難点がある。
また特許文献３は、地震による揺れが棚板上に設置された物品に伝わり難くいため、個々の物品の接触による損傷、棚からの物品の落下を防ぐ効果はあるが、構造的にある程度以上の揺れ、棚枠側と直角方向の揺れ以外には対処できないという難点がある。
また特許文献４は、物品を棚板へ固定するため、棚からの物品の落下だけでなく、個々の物品の接触による損傷を防ぐので他より優れるが、装置が大がかりであり地震が収まった後の装置の復旧が容易でないという難点がある。
本発明は、比較的簡単な構成で物品を固定して移動を制限できるため、棚からの物品の落下だけでなく、個々の物品の接触による損傷を防ぐことができ、地震後の復旧も容易な装置を安価に実現した点で異なる。
これにより特許文献１、２に対し、個々の物品の接触による損傷、物品の転倒による棚からの落下を防げる効果がある。
これにより特許文献３に対し、地震によるどの方向の揺れにおいても、個々の物品の接触による損傷、棚からの物品の落下の防止効果がある。
これにより特許文献４に対し、地震発生時の揺れに伴う個々の物品の接触による損傷、棚からの物品の落下を防ぎ、地震後の復旧が容易な装置を安価に実現する。However, although Patent Documents 1 and 2 prevent articles from falling from shelves, there is no restriction on the movement of articles due to earthquake shaking, so there is a risk of damage due to contact between individual articles. There is a problem that it may slip under the prevention bar.
In addition, Patent Document 3 has the effect of preventing damage due to contact of individual articles and falling of articles from the shelf because it is difficult for the shaking caused by an earthquake to be transmitted to the articles installed on the shelf board. There is a drawback that it cannot deal with vibrations other than vibrations in the direction perpendicular to the shelf frame side.
In addition, Patent Document 4 is superior to others in that it prevents not only falling of articles from the shelf but also damage due to contact of individual articles because it fixes articles to the shelf board, but the device is large and after the earthquake subsides. However, there is a problem that the recovery of the equipment is not easy.
Since the present invention can restrict the movement of articles by fixing them with a relatively simple structure, it is possible to prevent not only articles falling from shelves but also damage due to individual articles coming into contact with each other, and recovery after an earthquake is easy. It is different in that it realizes a simple device at a low cost.
As compared with Patent Literatures 1 and 2, this has the effect of preventing damage due to contact between individual articles, and preventing articles from falling off shelves due to overturning.
As compared with Patent Document 3, this has the effect of preventing damage due to contact of individual articles and dropping of articles from shelves in any direction of shaking caused by an earthquake.
In this way, compared to Patent Document 4, it is possible to prevent damage caused by individual articles coming into contact with each other due to shaking when an earthquake occurs, and to prevent articles from falling from shelves, thereby realizing a device that can be easily restored after an earthquake at a low cost.
本発明が解決しようとする課題は、比較的簡単な構成で地震発生時に棚にある個々の物品を固定することで物品が接触、転倒、落下せず、損傷しない物品落下防止装置を提供することである。 The problem to be solved by the present invention is to provide an article fall prevention device that has a relatively simple structure and prevents articles from coming into contact with each other, overturning, falling, and being damaged by fixing individual articles on a shelf when an earthquake occurs. is.

FIG. 6 shows a rear view of the shelf board 20 of the device for preventing articles from falling during normal operation. This is a shelf in which shelf boards 20 are arranged in four stages. In each shelf board 20 , the end of the belt 11 protrudes from the back side of the roller 24 , and the wire 15 is connected via a pulley 26 to a weight 17 installed on the weight installation section 18 .
図７に地震発生時の物品２５を固定した状態の物品落下防止装置の棚板２０の正面図と上面図を示す。
図８に地震発生時の物品落下防止装置の棚板２０の背面図を示す。
地震の揺れによって、図８の重り１７が重り設置部１８から落下することでベルト１１が棚板２０の背面側へ引き出され、ベルト１１が前部ベルトガイド２１、左右側部ベルトガイド２２から外れて内側にある全ての物品２５を棚板２０の中央にまとめて固定する。物品２５をまとめて固定することで、物品２５が転倒したり棚板２０から落下することがなく損傷を防止する。ベルト１１で効果的に物品２５を固定するために、物品２５の高さ、重心の位置を考慮し、ローラー２４の設置高さ、左右側部ベルトガイド２２の高さを最適に設定する。
重り設置部１８の周辺に重り１７が落下できるスペースを確保することで、どの方向の揺れに対しても物品落下防止装置が作動できる。FIG. 7 shows a front view and a top view of the shelf board 20 of the article fall prevention device in which the article 25 is fixed when an earthquake occurs.
FIG. 8 shows a rear view of the shelf board 20 of the device for preventing articles from falling when an earthquake occurs.
The weight 17 in FIG. 8 falls from the weight installation portion 18 due to the shaking of the earthquake, so that the belt 11 is pulled out to the back side of the shelf plate 20, and the belt 11 is disengaged from the front belt guide 21 and the left and right side belt guides 22. to fix all the articles 25 on the inside together in the center of the shelf board 20. - 特許庁By fixing the articles 25 together, the articles 25 do not overturn or fall off the shelf board 20, thereby preventing damage. In order to effectively fix the article 25 with the belt 11, the installation height of the roller 24 and the height of the left and right side belt guides 22 are optimally set in consideration of the height of the article 25 and the position of the center of gravity.
By securing a space around the weight setting portion 18 where the weight 17 can drop, the article drop prevention device can operate against shaking in any direction.
＜＜変形例＞＞
図９に示す変形例は、より強い揺れの地震を想定した場合の構成であるが、棚板２０の背面に単一方向ベルトロック２７を付加し、ゴム材質又はゴムを浸透させたベルト１１を用いることで、より強固に物品２５同士を固定できるためより物品２５の損傷防止効果が期待できる。単一方向ベルトロック２７は、棚板２０の背面側へのベルト１１の移動はフリーだが、逆方向にはロックする仕組みであり、全ての物品２５を固定した後に固定が緩くならないためのものである。地震の揺れが収まった後にロックを解除することで、棚板２０の板面側へベルト１１を引き込めるようになり、本装置を容易に元通りに復旧させることができる。揺れが強くなると、固定した物品２５全体が動いて棚板２０の背面側板面にぶつかるため、衝撃吸収シート２８を背面側板面に取り付けることで物品２５の損傷を防ぐ。<<Modification>>
The modification shown in FIG. 9 is a configuration in the case of assuming an earthquake with stronger shaking, but a unidirectional belt lock 27 is added to the back of the shelf board 20, and a belt 11 made of rubber material or permeated with rubber is attached. By using it, the articles 25 can be fixed to each other more firmly, so that an effect of preventing damage to the articles 25 can be expected. The unidirectional belt lock 27 allows the belt 11 to move freely toward the rear side of the shelf board 20, but locks in the opposite direction. be. By releasing the lock after the shaking of the earthquake subsides, the belt 11 can be retracted to the board surface side of the shelf board 20, and the apparatus can be easily restored to its original state. When the shaking becomes strong, the entire fixed article 25 moves and collides with the back side plate surface of the shelf board 20, so the article 25 is prevented from being damaged by attaching the shock absorbing sheet 28 to the back side plate surface.
強い揺れにより棚そのものが倒れる場合、一般的なスーパーや商店における商品棚のレイアウトでは前方向への転倒が多いが、本発明の変形例であれば物品２５の床への直撃が避けられるため、他の方式よりも被害を最小限に抑えられる。 When the shelf itself collapses due to strong shaking, most of the shelf layouts in general supermarkets and stores tip over in the forward direction. Minimizes damage compared to other methods.
