Description

車両、建造物等の壁面に上下に多数個が取着されて作業員の壁面昇降に利用される壁面昇降用照明付ステップ用具に係り、特に壁面に固定するための固定台座に、前記固定台座に起伏回動自在に枢着されたステップ部材の上面を照明する照明具を具え、前記ステップ部材の起立状態時に消灯、伏臥状態時に点灯させるスイッチ機構を具えた壁面昇降用照明付ステップ用具に関する。   It relates to a stepped tool for lighting up and down a wall surface that is used for raising and lowering a wall surface of a worker by attaching a large number of pieces up and down on the wall surface of a vehicle, a building, etc. The present invention relates to a stepped tool for lighting up and down a wall, comprising a lighting tool that illuminates the upper surface of a step member pivotably mounted on the top and bottom of the step member, and having a switch mechanism that turns off when the step member is in a standing state and turns on when the step member is in a prone state.

車両の壁面に取着された壁面昇降用ステップ具としては、鉄道車の連結部の壁面に設けられたものや、消防車両に備えられたものをよく見かけるが、開示されている発明としては、特許文献１の請求項３に、
「屋根上昇降ステップを、車端側外板寄りに配置し、該部品の表面は走行時に側外板と平滑状態に組込されたことを特徴とする高速車輌の車間接続装置」との記載がある。しかしこの発明におけるステップは、明細書の段落「００２５」の記述と「図５」「図７」とから、「車端の車体に垂直方向に設けられた複数のステップ穴に、リンクとロッドによって上下方向に回動自在な蓋が設けられ、車輌下部の取手を引けばステップ穴が開放し、走行時は蓋が閉じるというもので、高速車輌の走行時の騒音軽減を目的とした発明の一部をなすもので、作業員の壁面昇降時の利便性を求めた本発明の目的とは異なるものである。
一方建築分野で使用される昇降用ステップ用具の発明としては、特許文献２の、
「一端部に握持部を形成した足掛体の他端に仮設用パイプなどの被止着管体に抱持止着するクランプ部材を付設したことを特徴とする建築用登降装置」や、
特許文献３の、
「壁体や柱体などの被止体に止着する止着体と、この止着体に係止する足掛体とより成るものであって、止着体の板面を膨出させて被止着の表面との間に所定の係止間隔を介在せしめた係止条を形成し、一方足掛体の被止着体側に垂設した係止板に前記係止間隔に挿入契合する係合挿入部を設け、この係合挿入部の基部に前記係止条上縁に係止する当接係止縁を形成し、係合挿入部の巾を、前記止着板の係止着体の表面との係止間隔にほぼ合致させた巾に形成したことを特徴とする建築用登降装置」
等が開示されているが、いずれも建築作業時に鉄骨等に設置される登降装置であり、コンクリート打設時には鉄骨から撤去されることを前提としたものであり、本願発明の車両や建築物の壁面に固定、常備して使用するには構造が複雑過ぎ、また起伏回動自在にはなっていないという問題もある。
さらに、前記３件の特許文献とも、ステップ面を照明する手段を備えてはいない。 As the wall elevating and lowering step tool attached to the wall surface of the vehicle, what is provided on the wall surface of the connecting portion of the railway car and those provided in the fire engine are often seen, but as disclosed invention, In claim 3 of Patent Document 1,

The formed corrugated notch, 30 is a leaf spring, and 40 is a rear plate.

本考案の壁面昇降用照明付ステップ用具１は、図２の車両側壁面に取着した実施例の概要図に示すように、車両、建造物等の壁面に上下に多数個が取着されて作業員の壁面の昇降に利用されるものであって、図１に示すように該壁面昇降用照明付ステップ用具１を車両２や建造物等の壁面に固定する固定台座１０と、該固定台座１０に起伏回動自在に枢着されたステップ部材２０とからなり、該ステップ部材２０は、後方に前記固定台座１０に枢着される枢支部２２を有する方形フレーム状のステップ板２１で形成されている。
そして前記固定台座１０の前面上部には、ステップ板２１の上面を照明する照明具１４
と、照明光照射窓１６が設けられ、該照明具１４がステップ部材２０の起伏回動に連動して起立状態時に消灯、伏臥状態時に点灯させるスイッチ機構とを具えている。 As shown in the schematic diagram of the embodiment attached to the side wall surface of the vehicle in FIG. 2, the step tool 1 with lighting for raising and lowering the wall surface of the present invention is attached in large numbers up and down on the wall surface of the vehicle, building or the like. As shown in FIG. 1, a fixed base 10 for fixing the stepped tool 1 with lighting for moving up and down the wall to the wall surface of a vehicle 2 or a building, and the fixed base. The step member 20 is pivotally attached to the pedestal 10 so as to be freely pivoted up and down. The step member 20 is formed by a square frame-like step plate 21 having a pivotal support portion 22 pivotally attached to the fixed base 10 at the rear. ing.
An illuminator 14 for illuminating the upper surface of the step plate 21 is provided on the upper front surface of the fixed base 10.
And an illumination light irradiation window 16, and the illumination tool 14 is turned off in the standing state in conjunction with the raising and lowering rotation of the step member 20, and has a switch mechanism that is turned on in the prone state.

前記照明具１４を点滅させるスイッチ機構は、前記ステップ部材２０の起伏によって前記固定台座１０とステップ部材２０とが接近、離脱又はその間隔が変化する部位に設けられた近接スイッチ又はマイクロスイッチ１７で構成される。
本実施例で示すスイッチ機構は、図３に示すように前記固定台座１０に配設された板バネ３０と、その後方に配設されたマイクロスイッチ１７とによって構成され、前記固定台座１０に枢着されたステップ部材２０の前枢支部２２の後端部が前記ステップ部材２０起伏回動に伴って、伏臥状態時には図３（ａ）に示すように、前記板バネ３０を後方に撓曲させ、前記撓曲した板バネ３０が前記マイクロスイッチ１７のアクチュエータ１７ａを後方に押す作用によってマイクロスイッチ１７がＯＮとなり照明具１４が点灯する仕組みとなっている。そして、起立状態時には図３（ｂ）に示すように、前記板バネ３０の後方への撓曲が生ぜず、したがってマイクロスイッチ１７のアクチュエータ１７ａは前方に留まるので、マイクロスイッチ１７はＯＦＦでとなり照明具１４は消灯状態となる。
前記マイクロスイッチ１７はマイクロスイッチ取付板１７を介して後板４０にねじ止めされている。
本実施例における点灯機構のマイクロスイッチ１７に変えて 金属の存在を検出する誘導型近接スイッチ、物体の存在を検出する静電容量型スイッチを用いれば、前記近接スイッチが物体の接近を非接触で検知して照明具１４を０Ｎ・ＯＦＦすることから、高速応答、長寿命、高い信頼性の点灯機構が得られるので好ましい。
なお、前記照明具１４は伏臥状態にあるステップ板２１の上面を効率よく照射するために、下方に傾けられた取付基板１５の上に取り付けられ、照明光照射窓１６の形状も照射効果が高められるよう考慮されている。 The switch mechanism for blinking the illumination tool 14 is configured by a proximity switch or a micro switch 17 provided at a portion where the fixed base 10 and the step member 20 approach, separate from, or change in distance due to the undulation of the step member 20. Is done.
As shown in FIG. 3, the switch mechanism shown in this embodiment is composed of a leaf spring 30 disposed on the fixed base 10 and a microswitch 17 disposed on the rear side thereof. When the rear end portion of the front pivot support portion 22 of the worn step member 20 is in the prone state, the leaf spring 30 is bent backward as shown in FIG. The micro switch 17 is turned on by the action of the bent leaf spring 30 pushing the actuator 17a of the micro switch 17 rearward, and the illumination tool 14 is turned on. In the upright state, as shown in FIG. 3B, the leaf spring 30 is not bent backward, so that the actuator 17a of the microswitch 17 remains in the front, so that the microswitch 17 is turned off and illumination is performed. The tool 14 is turned off.
The microswitch 17 is screwed to the rear plate 40 via the microswitch mounting plate 17.
If an inductive proximity switch that detects the presence of a metal or a capacitance type switch that detects the presence of an object is used instead of the microswitch 17 of the lighting mechanism in the present embodiment, the proximity switch can contact the object without contact. Since the lighting device 14 is detected and turned off by 0 N, it is preferable because a lighting mechanism with a high-speed response, a long life, and a high reliability can be obtained.
