【考案の詳細な説明】
この考案は電気機器例えば屋内用配電箱、制御
盤等に使用する扉開閉用緩衝クツシヨン装置に関
するものである。[Detailed Description of the Invention] This invention relates to a shock absorbing cushion device for opening and closing doors used in electrical equipment such as indoor power distribution boxes and control panels.
屋内用配電箱などにおいて、配電箱の前面扉或
は後面扉には、各種の計器・継電器類の測定・制
御器具類が、多数実装されている。 In an indoor power distribution box or the like, a large number of measurement and control instruments such as various meters and relays are mounted on the front door or rear door of the power distribution box.
これ等の計器・継電器類は精密器類に属するも
のが多く、扉を開閉するとき、特に閉じるとき、
該扉に実装されているこれらの精密器類に衝撃を
与え、精度を狂わせたり、誤動作せしめたり、し
いては故障に至らしめることがある。また扉の当
り面は、衝突により塗装面が損傷・剥離し、発錆
の原因ともなる。 Many of these meters and relays belong to precision instruments, and when opening and closing the door, especially when closing it,
A shock may be applied to these precision instruments mounted on the door, causing them to lose their accuracy, malfunction, or even malfunction. In addition, the painted surface of the contact surface of the door may be damaged or peeled off due to a collision, causing rust.
このため、該扉には適当な緩衝作用効果のある
クツシヨンを設けて、扉を閉じるときに生じる衝
撃力を吸収或は緩衝させることが通常行われてい
る。 For this reason, it is common practice to provide the door with a cushion having a suitable cushioning effect to absorb or buffer the impact force generated when the door is closed.
この衝撃力緩衝用クツシヨンは、耐衝撃性、耐
摩耗性及び耐候性などに優れ、適当な弾力性を有

効率のよい緩衝用クツシヨン装置を提供するもの
である。 The present invention provides a shock absorbing cushion device that does not damage installed meters and relays, prevents the painted surface of the door from peeling off, and has good work efficiency.
以下、従来例並びに本考案の実施例を図面に基
づいて詳細に説明する。 Hereinafter, conventional examples and embodiments of the present invention will be described in detail based on the drawings.
第1図は配電箱、制御盤などの箱体の扉の部分
斜視図を示し、1は箱体、2は扉を示す。 FIG. 1 shows a partial perspective view of a door of a box such as a power distribution box or a control panel, where 1 indicates the box and 2 indicates the door.
第2図イは第1図のA−A線に沿つた平面断面
図で、従来の緩衝用クツシヨンを装着した状態を
示している。 FIG. 2A is a plan sectional view taken along the line A--A in FIG. 1, showing a state in which a conventional shock absorbing cushion is installed.
この従来例では、字状に加工された扉2の周
端部の折返面2′にクツシヨン3を装着している
が、扉2の面と折返面2′の縦巾Hが狭く、折返
面2′の横巾Dが広くなると板金加工が困難にな
る欠点があつた。 In this conventional example, the cushion 3 is attached to the folded surface 2' at the peripheral end of the door 2 processed into a letter shape, but the vertical width H of the surface of the door 2 and the folded surface 2' is narrow, and the folded surface When the width D of 2' becomes wider, there is a drawback that sheet metal processing becomes difficult.
第2図ロの例では、この加工の困難性を排除す
るため、折返面2′を別途L形金具22で形成し
ているが、この場合はL形金具22を扉2に溶接
等で固着する手段を要し、余分の加工時間を要す
る点で問題がある外、塗装作業も内面塗装が面倒
になるなどの問題点があつた。 In the example shown in Fig. 2B, in order to eliminate the difficulty of this processing, the folded surface 2' is formed with a separate L-shaped metal fitting 22, but in this case, the L-shaped metal fitting 22 is fixed to the door 2 by welding or the like. In addition to the problem of requiring extra processing time and the need for additional processing time, there were also problems with the painting process, such as the need for internal painting.
一方、クツシヨン3の装着についても従来例の
ものでは、その取付作業或は取付工数等の点で問
題がある。 On the other hand, regarding the attachment of the cushion 3, the conventional example has problems in terms of the installation work and the number of man-hours required for installation.
即ち、第3図イのものは中央部に凹部を有する
クツシヨン31凹部にボルト4をねじ入れ、クツ
シヨン31を固定する如くしているが、これでは
扉2の折返面2′にタツプ孔加工及びねじ締め工
具が必要となる。 That is, in the case of FIG. 3A, a bolt 4 is screwed into the recess of the cushion 31 having a recess in the center, and the cushion 31 is fixed. A screw tightening tool is required.
また、第3図ロの如く、T型クツシヨン32の
突起部に膨出部を設け、この突起部を扉2の折返
面22に設けた穴に打込む構成のものである(第
2図イ,ロも同じ)が、これはタツプ孔加工が不

面22の穴への打込みにハンマー等を用いる必要
があり、このため扉に衝撃が与えられ、扉に取付
けられた計器・継電器類に損傷を生じる可能性が
ある。 In addition, as shown in FIG. 3B, the protrusion of the T-shaped cushion 32 is provided with a bulge, and this protrusion is driven into a hole provided in the folded surface 22 of the door 2 (FIG. 2). This method does not require tap hole drilling and can reduce the number of processing steps, but on the other hand, it is necessary to use a hammer or the like to drive into the hole in the folded surface 22, which may cause impact to the door. This may cause damage to the meters and relays installed on the door.
以上の如く、従来用いられている緩衝用クツシ
