Description

本発明は、車両整備場において給排ホースが車両の供給口や排出口から分離されて、適正な収納位置に収納されていることを確認するための収納確認装置に関する。 The present invention relates to a storage confirmation device for confirming that a supply / discharge hose is separated from a supply port and a discharge port of a vehicle and stored in an appropriate storage position in a vehicle maintenance shop.

この種の収納確認装置は、例えば特許文献１に公知である。そこでは、汚物排出ホースを載置するための載置台と、載置台のホース載置部に汚物排出ホースが載置してあるかどうかを検知する検知部と、検知部から出力される検知信号に基づいて汚物排出ホースの有無を判定する判定部と、報知部などで収納確認装置を構成している。検知部は照射部および受光部と反射板などの光センサーで構成してあり、ホース載置部に汚物排出ホースが載置してあるか否かを、受光部の受光状態の有無によって検知している。報知部は回転灯、スピーカー、ブザーなどで構成され、汚物排出ホースがホース載置部に載置されていない場合、つまり汚物排出ホースが車両に接続されたままである場合に報知動作を実行して、作業者の注意を喚起する。 This type of storage confirmation device is known, for example, from Patent Document 1. There, a mounting table for mounting the waste discharge hose, a detection unit for detecting whether the waste discharge hose is mounted on the hose mounting part of the mounting table, and a detection signal output from the detection unit The determination unit for determining the presence or absence of the filth discharge hose, the notification unit, and the like constitute a storage confirmation device. The detection unit is composed of an irradiation unit, a light receiving unit and a light sensor such as a reflector, and detects whether or not the filth discharge hose is mounted on the hose mounting unit based on the presence or absence of the light receiving state of the light receiving unit. ing.

特開２０１０−２８５０２７号公報（段落番号００２９〜００３２、図１）JP 2010-285027 A (paragraph numbers 0029 to 0032, FIG. 1)

特許文献１の収納確認装置によれば、汚物排出ホースが車両に接続されたままであることを回転灯で明示するので、汚物排出作業が終了したのち、汚物排出ホースが接続された状態のままで車両が発進して、汚物排出ホースが引き千切られてしまう事故を防止できる。しかし、汚物排出ホースを収納するために載置台を用意し、そのホース載置部に検知部を設ける必要があるので、汚物排出ホースを含む収納確認装置の占めるスペースが大きくなるのを避けられず、例えば、車両整備場における作業用ピットが狭い場合に設置するのが困難であった。また、収納確認装置の全体コストが嵩む不利もあった。 According to the storage confirmation device of Patent Literature 1, since the rotating lamp clearly indicates that the filth discharge hose remains connected to the vehicle, the filth discharge hose remains connected after the filth discharge operation is completed. It is possible to prevent an accident in which the vehicle starts and the filth discharge hose is torn off. However, since it is necessary to prepare a mounting table for storing the filth discharge hose and to provide a detection unit in the hose mounting portion, it is inevitable that the space occupied by the storage confirmation device including the filth discharge hose becomes large. For example, it is difficult to install when a work pit in a vehicle maintenance shop is narrow. In addition, there is a disadvantage that the overall cost of the storage confirmation device increases.

特許文献１の収納確認装置においては、汚物排出ホースの端部に固定した接続金具を蓋金具で閉止する必要がある。しかし、蓋金具の重量が大きく、しかも接続金具に対して位置合わせした状態で回転操作しなければならないため、蓋金具の着脱に余分な手間が掛かる。さらに、蓋金具の重量分だけ汚物排出ホースの全体重量が大きくなり、ホースの取出しあるいは収納を行うのに大きな力を要し作業性が悪い。この種の作業は、アルバイト従業員や、高齢の臨時作業者などによって行われることが多いため、作業性が悪いことに関連して作業の安全性を確保しにくい不利もある。検知部を構成する反射板が、ホース載置部に臨んで配置してあるため、汚物排出ホースを収納する際に反射板に汚物が付着することがあり、そのつど反射板を清掃しなければならない煩わしさがあった。 In the storage confirmation device of Patent Document 1, it is necessary to close the connection fitting fixed to the end of the filth discharge hose with the lid fitting. However, since the weight of the lid fitting is heavy and the rotating operation has to be performed in a state of being aligned with the connection fitting, extra effort is required for attaching and detaching the lid fitting. Further, the entire weight of the waste discharging hose is increased by the weight of the lid fitting, and a large force is required to take out or store the hose, resulting in poor workability. Since this type of work is often performed by part-time employees or elderly temporary workers, there is a disadvantage that it is difficult to ensure the safety of work in connection with poor workability. Since the reflector that constitutes the detector is located facing the hose mounting part, dirt may adhere to the reflector when the filth discharge hose is stored, and the reflector must be cleaned each time. There was annoying trouble.

本発明の目的は、収納確認装置が占めるスペースを小さくでき、しかも全体コストを削減して収納確認装置の導入費用を低コスト化できる、車両整備場における給排ホースの収納確認装置を提供することにある。
本発明の目的は、蓋金具の接続金具に対する着脱を簡便に、しかも安全に行なうことができる、車両整備場における給排ホースの収納確認装置を提供することにある。 It is an object of the present invention to provide a storage confirmation device for a supply / discharge hose in a vehicle maintenance yard that can reduce the space occupied by the storage confirmation device and can reduce the overall cost to reduce the introduction cost of the storage confirmation device.

接続金具９の金具端面１０と正対する蓋部２１にガスケット２３を設ける。接続金具９を蓋金具１５に連結した状態において、金具端面１０を含む開口面をガスケット２３で閉止する。 A gasket 23 is provided on the lid portion 21 that faces the metal fitting end surface 10 of the connection metal fitting 9. In a state where the connection fitting 9 is coupled to the lid fitting 15, the opening surface including the fitting end face 10 is closed with the gasket 23.

蓋部２１に一対の平行な対向側部２４と、対向側部２４の上端に連続する係合案内縁２５とを設ける。図４に示すように、一対の対向側部２４の対向長さＢ１を、接続金具９の一対の係止体１２の対向間隔Ｂ２より僅かに小さく設定する。 The lid portion 21 is provided with a pair of parallel opposing side portions 24 and an engagement guide edge 25 continuous with the upper end of the opposing side portion 24. As shown in FIG. 4, the facing length B 1 of the pair of facing side portions 24 is set slightly smaller than the facing distance B 2 of the pair of locking bodies 12 of the connection fitting 9.

蓋金具１５に連結した接続金具９の上端より上側にはみ出る蓋部２１の上部外面に、吊持具２９で支持されるブラケット３０を固定する。蓋部２１の上下中途部の外面に、蓋金具１５を保持するハンドル３２を固定する。 A bracket 30 supported by a lifting tool 29 is fixed to the upper outer surface of the lid portion 21 that protrudes above the upper end of the connection fitting 9 connected to the lid fitting 15. A handle 32 for holding the lid metal fitting 15 is fixed to the outer surface of the middle part of the lid part 21 in the vertical direction.

検知部１６は、投光器１６ａと受光器１６ｂを備えた回帰反射型の光センサーユニットで構成する。制御部１８は、接続金具９が蓋金具１５から分離されて、受光器１６ｂの検知信号が出力されていない状態において、警告具１７を作動させるように構成する。 The detection unit 16 is configured by a retroreflective optical sensor unit including a projector 16a and a light receiver 16b. The control unit 18 is configured to operate the warning device 17 in a state where the connection fitting 9 is separated from the lid fitting 15 and the detection signal of the light receiver 16b is not output.

接続金具９の金具端面１０の上端部と正対する蓋部２１に検知窓２６を開口し、検知窓２６の外面に臨んで断面ハット形のセンサーホルダー３１を固定する。センサーホルダー３１の上壁の内面に検知部１６を配置する。 A detection window 26 is opened in the lid portion 21 that faces the upper end of the metal fitting end surface 10 of the connection fitting 9, and a hat-shaped sensor holder 31 is fixed facing the outer surface of the detection window 26. The detection unit 16 is disposed on the inner surface of the upper wall of the sensor holder 31.

車両整備場の作業ピットＰに設けたキャットウォーク６の通路下面に、蓋金具１５を吊持する金属製のチェーン２９と、警告具１７とを配置する。蓋金具１５の吊持高さＨ１を、車両側の給排口４の地上高さＨ２にほぼ一致させる。 A metal chain 29 for suspending the lid fitting 15 and a warning device 17 are arranged on the lower surface of the passage of the catwalk 6 provided in the work pit P of the vehicle maintenance yard. The suspended height H1 of the lid fitting 15 is made to substantially coincide with the ground height H2 of the vehicle-side supply / discharge port 4.

本発明においては、給排ホース１の接続金具９に連結される蓋金具１５と、接続金具９の有無を検知する検知部１６と、警告具１７と、警告具１７の作動状態を制御する制御部１８などで収納確認装置を構成して、同装置の全体構造を簡素化した。従って、本発明の収納確認装置によれば、給排ホースを載置するための載置台が不可欠であった従来のこの種の装置に比べて、全体コストを削減して装置の導入費用を低コスト化できる。また、吊持具２９で所定の地上高さに吊持した蓋金具１５に接続金具９を連結して、給排ホース１を吊持した状態で収納するので、収納確認装置の設置に要するスペースを最小限化でき、車両整備用の作業ピットＰが狭い場合にも収納確認装置を容易に設置できる。 In the present invention, a lid fitting 15 connected to the connection fitting 9 of the supply / discharge hose 1, a detection unit 16 that detects the presence / absence of the connection fitting 9, a warning tool 17, and a control that controls the operating state of the warning tool 17. The storage confirmation device is composed of the part 18 and the like, and the overall structure of the device is simplified. Therefore, according to the storage confirmation device of the present invention, compared with a conventional device of this type in which a mounting table for mounting the supply / discharge hose is indispensable, the overall cost is reduced and the introduction cost of the device is reduced. Cost can be reduced. Further, since the connection fitting 9 is connected to the lid fitting 15 that is suspended at a predetermined ground height by the lifting tool 29 and the supply / discharge hose 1 is suspended, the space is required for installing the storage confirmation device. The storage confirmation device can be easily installed even when the work pit P for vehicle maintenance is narrow.

さらに、接続金具９に設けた一対の係止体１２を、蓋部２１の対向側部２４に対して相対的にスライド操作するだけで、接続金具９と蓋金具１５を連結し、あるいは分離できるので、蓋金具１５と接続金具９との着脱を簡便に、しかも安全に行なうことができる。もちろん、給排ホース１が、適正な収納位置に収納されているか否かを収納確認装置で確認するので、給排ホース１が車両に接続された状態のままで車両が発進してホースが引き千切られる事故を確実に防止できる。 Furthermore, the connection fitting 9 and the lid fitting 15 can be connected or separated by simply sliding the pair of locking bodies 12 provided on the connection fitting 9 relative to the opposing side portion 24 of the lid 21. Therefore, the attachment / detachment of the lid fitting 15 and the connection fitting 9 can be performed easily and safely. Of course, since the storage confirmation device checks whether the supply / discharge hose 1 is stored in an appropriate storage position, the vehicle starts and the hose is pulled while the supply / discharge hose 1 remains connected to the vehicle. Accidents can be reliably prevented.

蓋部２１にガスケット２３を設け、接続金具９を蓋金具１５に連結した状態において、金具端面１０を含む開口面をガスケット２３で閉止すると、給排ホース１に雨水や雪、あるいは塵埃が入込むのを確実に防止できる。とくに給排ホース１が飲料水を供給する給水ホースである場合には、飲料水に雨水、雪、塵埃などが混入するのを確実に防止して、衛生的な状態を保持できる。また、給排ホースが汚物排出ホース１である場合には、異臭や悪臭が汚物排出ホース１の収納部の周辺に拡散するのを防止でき、さらに昆虫が接続金具９に群がって不衛生な状態になるのを防止できる。 When the gasket 23 is provided on the lid 21 and the connection fitting 9 is coupled to the lid fitting 15, the opening surface including the fitting end face 10 is closed with the gasket 23, and rainwater, snow, or dust enters the supply / discharge hose 1. Can be surely prevented. In particular, when the water supply / discharge hose 1 is a water supply hose for supplying drinking water, it is possible to reliably prevent rainwater, snow, dust and the like from being mixed into the drinking water and maintain a sanitary state. Further, when the supply / discharge hose is the filth discharge hose 1, it is possible to prevent an unpleasant odor or bad odor from spreading around the storage portion of the filth discharge hose 1, and further, insects gather in the connection fitting 9 and are unsanitary. Can be prevented.

蓋部２１に設けた一対の対向側部２４の対向長さＢ１が、接続金具９の一対の係止体１２の対向間隔Ｂ２より僅かに小さく設定してあると、蓋金具１５と接続金具９との着脱を簡便にしかも円滑に行えるので、接続金具９の着脱作業をより安全に行なうことができる。 When the opposing length B1 of the pair of opposing side portions 24 provided on the lid portion 21 is set slightly smaller than the opposing distance B2 of the pair of locking bodies 12 of the connection fitting 9, the lid fitting 15 and the connection fitting 9 are provided. Can be easily and smoothly attached and detached, so that the attaching and detaching work of the connection fitting 9 can be performed more safely.

蓋部２１の上部外面に配置したブラケット３０を吊持具２９で支持すると、蓋金具１５を常に安定した姿勢で吊持できる。また、蓋部２１に固定したハンドル３２を片手で保持することにより、蓋金具１５の姿勢や高さなどを自在に操作できる。従って、蓋金具１５と接続金具９を着脱する際に、両者の位置合わせや、相対スライド動作をより的確に行って、蓋金具１５と接続金具９の着脱を容易に、しかも安全に行なうことができる。蓋金具１５に連結した接続金具９の上端より上側にはみ出る蓋部２１の上部外面に、ブラケット３０を固定するので、接続金具９を蓋金具１５に対して着脱する際に、ブラケット３０が邪魔になるのを解消できる。さらに、接続金具９の上端より上側にはみ出る蓋部２１の壁面を、仮位置決め面として利用することができるので、接続金具９の蓋金具１５に対する連結をより容易に行える。 When the bracket 30 disposed on the upper outer surface of the lid portion 21 is supported by the suspension tool 29, the lid fitting 15 can be suspended in a stable posture at all times. Further, by holding the handle 32 fixed to the lid portion 21 with one hand, the posture and height of the lid fitting 15 can be freely operated. Therefore, when attaching and detaching the cover fitting 15 and the connection fitting 9, both the positioning and relative sliding operation can be performed more accurately, and the attachment and detachment of the cover fitting 15 and the connection fitting 9 can be performed easily and safely. it can. Since the bracket 30 is fixed to the upper outer surface of the lid 21 that protrudes above the upper end of the connection fitting 9 connected to the lid fitting 15, the bracket 30 becomes an obstacle when the connection fitting 9 is attached to and detached from the lid fitting 15. Can be eliminated. Furthermore, since the wall surface of the lid portion 21 that protrudes above the upper end of the connection fitting 9 can be used as a temporary positioning surface, the connection fitting 9 can be more easily coupled to the lid fitting 15.

投光器１６ａと受光器１６ｂを備えた回帰反射型の光センサーユニットで検知部１６を構成すると、透過型の光センサーユニットで検知部１６を構成する場合に比べて、検知部１６を一個所に集約できるので、その分だけ収納確認装置の構造を簡素化できる。とくに、接続金具９の金具端面１０を利用して、投受光を行なう場合には、反射鏡や反射板を省略することができるので、検知部１６のコストをさらに節約することができる。また、回帰反射型の光センサーユニットで構成した検知部１６は、非接触で接続金具９の有無を検知するので故障する可能性が低く、検知機能を長期にわたって安定した状態で発揮できる。接続金具９が蓋金具１５から分離された状態で警告具１７を作動させるのは、給排ホース１が使用中であることと、警告具１７が作動していることとを一致させて、作業者に対する警告具１７の注意喚起作用を明確化し理解しやすくして、勘違いを排除するためである。 When the detection unit 16 is configured with a retroreflective optical sensor unit including the projector 16a and the light receiver 16b, the detection unit 16 is integrated into one place as compared with the case where the detection unit 16 is configured with a transmission type optical sensor unit. Therefore, the structure of the storage confirmation device can be simplified accordingly. In particular, when light is projected and received using the metal fitting end surface 10 of the connection metal 9, the reflecting mirror and the reflecting plate can be omitted, so that the cost of the detection unit 16 can be further saved. Moreover, since the detection part 16 comprised with the retroreflection type optical sensor unit detects the presence or absence of the connection metal fitting 9 without contact, there is little possibility of failure, and the detection function can be exhibited in a stable state over a long period of time. The operation of the warning device 17 in a state where the connection fitting 9 is separated from the lid fitting 15 is performed by matching the fact that the supply / discharge hose 1 is in use and the operation of the warning device 17. This is for clarifying and facilitating the alerting action of the warning tool 17 to the person and eliminating misunderstandings.

検知窓２６の外面にセンサーホルダー３１を固定し、その上壁の内面に検知部１６を配置すると、検知部１６が直射日光、雨滴あるいは雪片などに晒されるのをセンサーホルダー３１で防止できるので、検知部１６が誤作動するのを防止できる。とくに、検知部１６が光センサーで構成してある場合には、投光器１６ａの投光面や受光器１６ｂの受光面に雨滴や雪片が付着するのを防止して誤作動状態に陥るのを確実に防止できる。 If the sensor holder 31 is fixed to the outer surface of the detection window 26 and the detection unit 16 is disposed on the inner surface of the upper wall, the sensor holder 31 can prevent the detection unit 16 from being exposed to direct sunlight, raindrops, snowflakes, etc. It is possible to prevent the detection unit 16 from malfunctioning. In particular, when the detection unit 16 is constituted by an optical sensor, it is possible to prevent the raindrops and snowflakes from adhering to the light projecting surface of the light projecting device 16a and the light receiving surface of the light receiving device 16b, and to ensure that a malfunction occurs. Can be prevented.

キャットウォーク６の通路下面にチェーン２９と、警告具１７とを配置すると、チェーン２９や警告具１７を取付けるための柱や支柱、あるいは台等を別途設ける必要がないので、収納確認装置の設置構造をさらに簡素化して、そのコストを削減できる。また、警告具１７が表示灯や警告等などの発光表示具である場合には、日光に対する遮蔽物のない空間に発光表示具が設けてある場合に比べて、通路下面に配置した警告具１７の発光状態を明確化して、作業者の注意をさらに確実に喚起できる。蓋金具１５の吊持高さＨ１が、車両側の給排口４の地上高さＨ２にほぼ一致させてあると、接続金具９を大きく動かす必要もなく蓋金具１５と給排口４に着脱することができるので、車両に対する給水作業や汚物抜取り作業の作業負荷をさらに軽減できる。 When the chain 29 and the warning device 17 are arranged on the lower surface of the passage of the catwalk 6, there is no need to separately provide a column, a column, or a stand for attaching the chain 29 and the warning device 17, so the installation structure of the storage confirmation device Can be further simplified and its cost can be reduced. In addition, when the warning tool 17 is a light emitting display tool such as an indicator lamp or a warning, the warning tool 17 disposed on the lower surface of the passage is compared with a case where the light emitting display tool is provided in a space without a shield against sunlight. By clarifying the light emission state, it is possible to call the operator's attention more reliably. When the suspended height H1 of the lid fitting 15 is substantially equal to the ground height H2 of the vehicle-side supply / exhaust port 4, it is not necessary to move the connecting bracket 9 greatly, and the lid bracket 15 and the supply / exhaust port 4 are attached / detached. Therefore, it is possible to further reduce the work load of the water supply work and the trash removal work for the vehicle.

蓋部２１は小判形に形成されていて、上下方向に平行な一対の対向側部２４と、対向側部２４の上端に連続する半円状の係合案内縁２５とを備えている。対向側部２４に連続する蓋部２１の下縁は部分円弧状に形成してあり、この下縁に沿って部分円弧状に折曲げられた受止部２２が溶接してある。蓋部２１およびガスケット２３の上部には、横長四角形状の検知窓２６が開口してあり、同窓２６を介して金具端面１０の上部と正対する蓋外面に検知部１６が配置してある。受止部２２の中央部には水抜穴２７が形成してある。 The lid portion 21 is formed in an oval shape, and includes a pair of opposing side portions 24 parallel to the vertical direction and a semicircular engagement guide edge 25 continuing to the upper end of the opposing side portion 24. The lower edge of the lid portion 21 continuing to the opposite side portion 24 is formed in a partial arc shape, and a receiving portion 22 bent in a partial arc shape along this lower edge is welded. A horizontally elongated detection window 26 is opened above the lid 21 and the gasket 23, and the detection unit 16 is arranged on the outer surface of the cover facing the upper part of the metal end face 10 through the window 26. A drain hole 27 is formed at the center of the receiving portion 22.

接続金具９は、その金具端面１０に設けた一対の係止体１２と、蓋部２１の対向側部２４とを相対的にスライド係合するだけの簡単な操作で、汚物排出ホース１を蓋金具１５に連結して収納状態に保持できる。因みに、従来の蓋金具は、蓋金具側の係止体をバヨネット爪と位置合わせした状態で蓋金具を回転操作して、蓋金具と接続金具を連結していたが、こうした面倒な操作は一切必要ない。同様に、接続金具９を蓋部２１から取外す場合には、一対の係止体１２と、蓋部２１の対向側部２４とを相対的にスライド操作するだけで、給排ホース１を蓋金具１５から容易に分離できる。一対の係止体１２と、蓋部２１の対向側部２４とのスライド係合、あるいはスライド操作を簡便に行うために、一対の対向側部２４の対向長さＢ１は、接続金具９の一対の係止体１２の対向間隔Ｂ２より僅かに小さく設定してある（図４参照）。接続金具９を蓋金具１５に接続した状態では、ガスケット２３が金具端面１０を含む開口面を閉止するので、悪臭が周辺部に拡散するのを防止できる。 The connection fitting 9 covers the filth discharge hose 1 with a simple operation by relatively slidingly engaging the pair of locking bodies 12 provided on the end face 10 of the fitting and the opposite side portion 24 of the lid portion 21. It can be connected to the metal fitting 15 and held in a stored state. By the way, in the conventional lid fitting, the lid fitting was rotated with the locking body on the lid fitting side aligned with the bayonet claw, and the lid fitting and the connecting fitting were connected. unnecessary. Similarly, when the connection fitting 9 is removed from the lid portion 21, the supply / discharge hose 1 can be attached to the lid fitting simply by relatively sliding the pair of locking bodies 12 and the opposite side portion 24 of the lid portion 21. 15 can be easily separated. In order to easily perform sliding engagement or sliding operation between the pair of locking bodies 12 and the facing side portion 24 of the lid portion 21, the facing length B 1 of the pair of facing side portions 24 is a pair of the connection fitting 9. Is set slightly smaller than the facing interval B2 of the locking body 12 (see FIG. 4). In a state where the connection fitting 9 is connected to the lid fitting 15, the gasket 23 closes the opening surface including the fitting end face 10, so that it is possible to prevent malodor from spreading to the peripheral portion.

小判形に形成した蓋部２１の外面には、図１に示すように、上側から順に金属製のチェーン（吊持具）２９で支持されるブラケット３０と、検知部１６を取付けるためのセンサーホルダー３１と、蓋金具１５を保持するハンドル３２が記載順に固定してある。ブラケット３０は、接続金具９を蓋金具１５に装着した状態において、接続金具９の上端より上側にはみ出る蓋部２１の上部外面に固定してあり、その連結穴３３に通したシャックル３４と、シャックル３４にねじ込まれるボルト３５を介してチェーン２９に連結してある。図２に示すように、チェーン２９で支持した蓋金具１５の吊持高さＨ１は、車両側の排出口４の地上高さＨ２にほぼ一致させてあるので、接続金具９の排出バルブ３に対する着脱を容易に行なうことができる。 As shown in FIG. 1, a bracket 30 supported by a metal chain (suspending tool) 29 in order from the upper side and a sensor holder for mounting the detection unit 16 are provided on the outer surface of the lid portion 21 formed in an oval shape. 31 and a handle 32 for holding the lid fitting 15 are fixed in the order of description. The bracket 30 is fixed to the upper outer surface of the lid portion 21 that protrudes above the upper end of the connection fitting 9 in a state where the connection fitting 9 is attached to the lid fitting 15, and includes a shackle 34 that passes through the connecting hole 33, and a shackle It is connected to the chain 29 via a bolt 35 that is screwed into 34. As shown in FIG. 2, the suspended height H 1 of the lid fitting 15 supported by the chain 29 is substantially equal to the ground height H 2 of the discharge port 4 on the vehicle side. It can be easily attached and detached.

図６に示すように、センサーホルダー３１は、ステンレス薄板を断面ハット形に折曲げて形成してあり、全体が検知窓２６の外面に臨む状態で配置されて、上下一対の取付座３６が４個のビス３７で固定してある。ハンドル３２はステンレス製の丸棒をコ字状に折曲げて形成してあり、その長手方向中心が汚物排出ホース１の中心と対向する状態で水平に配置されて、図示していないビスで蓋部２１に固定してある。図１に示すように、チェーン２９の上端は、キャットウォーク６の通路下面に固定してある。 As shown in FIG. 6, the sensor holder 31 is formed by bending a thin stainless steel plate into a cross-sectional hat shape, and is disposed in a state where the entire surface faces the outer surface of the detection window 26. Each screw 37 is fixed. The handle 32 is formed by bending a round bar made of stainless steel into a U-shape, and the handle 32 is horizontally arranged with its longitudinal center facing the center of the filth discharge hose 1 and is covered with a screw (not shown). It is fixed to the part 21. As shown in FIG. 1, the upper end of the chain 29 is fixed to the lower surface of the passage of the catwalk 6.

図３および図４に示すように、検知部１６は、投光器１６ａと受光器１６ｂを備えた市販の回帰反射型の光センサーユニットで構成されており、先に説明したセンサーホルダー３１の上壁の内面にビスで固定してある。センサーホルダー３１で支持された検知部１６は、接続金具９を蓋金具１５に装着した状態において、投光器１６ａおよび受光器１６ｂが検知窓２６を介して金具端面１０と対向しているので、投光器１６ａから照射されて金具端面１０で反射した検知光を受光器１６ｂで受光できる。また、断面がハット形のセンサーホルダー３１の上壁の内面に検知部１６を配置するので、雨天時や積雪時に、投光器１６ａの投光面や受光器１６ｂの受光面に雨滴や雪片が付着するのを防止できる。さらに、汚物排出ホース１を収納している状態においては検知窓２６が金具端面１０で塞がれるので、埃などの塵埃が投光面および受光面に付着するのをよく防止でき、全体として、収納確認装置のメンテナンスの手間を軽減できる。 As shown in FIGS. 3 and 4, the detection unit 16 includes a commercially available retro-reflective optical sensor unit including a projector 16 a and a light receiver 16 b, and the upper wall of the sensor holder 31 described above. It is fixed on the inner surface with screws. The detector 16 supported by the sensor holder 31 has the light projector 16a and the light receiver 16b facing the metal fitting end surface 10 through the detection window 26 in a state where the connection metal fitting 9 is attached to the cover metal fitting 15, and thus the light projector 16a. Can be received by the light receiving device 16b. In addition, since the detection unit 16 is disposed on the inner surface of the upper wall of the sensor holder 31 having a hat-shaped cross section, raindrops and snowflakes adhere to the light projecting surface of the light projector 16a and the light receiving surface of the light receiver 16b in the rain or snow. Can be prevented. Further, in the state where the waste discharge hose 1 is housed, the detection window 26 is blocked by the metal fitting end surface 10, so that dust such as dust can be well prevented from adhering to the light projecting surface and the light receiving surface. The maintenance labor of the storage confirmation device can be reduced.

警告具１７は、ドーム状のレンズ内部にＬＥＤ光源を備えた市販の防水型表示灯からなり、レンズ部分は黄色に着色してある。警告具１７は、キャットウォーク６の通路下面にレンズ部分が下向きになる状態で固定してある。制御部１８は、プラスチック製の筐体の内部にサーキットブレーカー、ＤＣ電源回路、補助リレー、端子台、電源スイッチなどを収容して構成してあり、その筐体を開閉する蓋体の外面に収納確認装置が作動中であることを明示するランプが設けてある。制御部１８は、ＤＣ電源回路で整流した直流電流を、投光器１６ａおよび警告具１７に供給しており、接続金具９が蓋金具１５から分離された状態において、受光器１６ｂの受光状態に基づいて警告具１７を作動させる。 The warning device 17 is a commercially available waterproof indicator lamp having an LED light source inside a dome-shaped lens, and the lens portion is colored yellow. The warning tool 17 is fixed to the lower surface of the passage of the catwalk 6 with the lens portion facing downward. The control unit 18 is configured by accommodating a circuit breaker, a DC power circuit, an auxiliary relay, a terminal block, a power switch, and the like inside a plastic casing, and is stored on the outer surface of a lid that opens and closes the casing. A lamp is provided to clearly indicate that the verification device is in operation. The control unit 18 supplies the direct current rectified by the DC power supply circuit to the projector 16 a and the warning device 17, and in a state where the connection fitting 9 is separated from the lid fitting 15, based on the light receiving state of the light receiver 16 b. The warning device 17 is activated.

不使用状態における汚物排出ホース１は、図２および図５に示すように、ホース端部に設けた接続金具９が蓋金具１５に連結された状態で、作業ピットＰに沿って収納されており、制御部１８の電源はオフされ、警告具１７は消灯状態になっている。車両の汚物タンク２から汚物を排出する場合には、まず、制御部１８の電源をオン状態に切換えて、投光器１６ａを発光させ検知光を照射させる。このとき、検知部１６の投光器１６ａと受光器１６ｂは、検知窓２６を介して金具端面１０の上部と正対しているので、投光器１６ａから照射された検知光は、金具端面１０で反射されて受光器１６ｂに受光され、受光器１６ｂから制御部１８に対して検知信号が出力される。検知信号を受取った制御部１８は、汚物排出ホース１が蓋金具１５に連結された状態であると判定して、警告具１７の消灯状態を維持する。 As shown in FIGS. 2 and 5, the waste discharge hose 1 in the unused state is stored along the work pit P in a state where the connection fitting 9 provided at the end of the hose is coupled to the lid fitting 15. The power source of the control unit 18 is turned off, and the warning tool 17 is turned off. In order to discharge filth from the filth tank 2 of the vehicle, first, the power source of the control unit 18 is switched to the on state, the projector 16a is caused to emit light, and the detection light is emitted. At this time, since the light projector 16a and the light receiver 16b of the detection unit 16 are directly opposed to the upper part of the metal end surface 10 through the detection window 26, the detection light emitted from the light projector 16a is reflected by the metal end surface 10. Light is received by the light receiver 16 b and a detection signal is output from the light receiver 16 b to the control unit 18. The control unit 18 that has received the detection signal determines that the filth discharge hose 1 is connected to the lid fitting 15 and maintains the warning instrument 17 in the extinguished state.

次に、接続金具９を蓋金具１５から取外すが、このとき、接続金具９の操作ハンドル１１を片方の手で握り持ち、他方の手で蓋金具１５のハンドル３２を握った状態で、接続金具９を上向きにスライド操作することにより、接続金具９を蓋金具１５から簡単に取外すことができる。この状態における投光器１６ａおよび受光器１６ｂは、検知窓２６を介して汚物排出ホース１が占めていた空間と正対する。そのため、投光器１６ａから照射された検知光が反射されて受光器１６ｂに受光されることはなく、受光器１６ｂは無信号状態を維持する。このように、接続金具９が蓋金具１５から分離されたのちの制御部１８は、汚物排出ホース１が排出バルブ３に接続されている状態であるとみなして警告具１７を点灯する。 Next, the connection fitting 9 is removed from the lid fitting 15. At this time, the operation fitting 11 of the connection fitting 9 is held with one hand and the handle 32 of the lid fitting 15 is grasped with the other hand. The connection fitting 9 can be easily detached from the lid fitting 15 by sliding the 9 upward. The projector 16 a and the light receiver 16 b in this state face the space occupied by the filth discharge hose 1 through the detection window 26. Therefore, the detection light emitted from the projector 16a is not reflected and received by the light receiver 16b, and the light receiver 16b maintains a no-signal state. As described above, the control unit 18 after the connection fitting 9 is separated from the lid fitting 15 turns on the warning device 17 assuming that the filth discharge hose 1 is connected to the discharge valve 3.

警告具１７が点灯している状態は、車両のメンテナンス作業に携わっている作業者が一見するだけで確認できるので、汚物排出ホース１が収納位置へ戻されていない状態であることを作業者に報知できる。つまり、作業者の注意を喚起して、汚物排出ホース１を収納位置へ戻す必要があることを明確に報知できる。排出バルブ３から取外した汚物排出ホース１が、作業ピットＰのどこかに置いてある場合にも、同様に警告具１７は点灯状態を維持する。 The state in which the warning tool 17 is lit can be confirmed at a glance by an operator engaged in the maintenance work of the vehicle. Therefore, the operator is informed that the waste discharge hose 1 has not been returned to the storage position. Can be notified. That is, it is possible to clearly notify that it is necessary to alert the operator and return the waste discharge hose 1 to the storage position. Even when the waste discharge hose 1 removed from the discharge valve 3 is placed somewhere in the work pit P, the warning device 17 similarly maintains the lighting state.

次に、接続金具９を排出バルブ３の排出口４に接続し、排出バルブ３を開状態に切換えて、汚物を汚物排出ホース１を介して作業ピットＰの地下に設けた下水道へ排出する。汚物の排出が終了したら、排出バルブ３を閉状態に切換えたのち、接続金具９を排出バルブ３から切離して水洗いしたのち、再び蓋金具１５に連結して収納する。このとき、接続金具９の操作ハンドル１１を片方の手で握り持ち、他方の手で蓋金具１５のハンドル３２を握った状態で、図４に示すように、接続金具９の一対の係止体１２を、蓋金具１５の上方から係合案内縁２５に仮掛止することにより、接続金具９を蓋金具１５に容易に連結できる。 Next, the connection fitting 9 is connected to the discharge port 4 of the discharge valve 3, the discharge valve 3 is switched to the open state, and the filth is discharged to the sewer provided in the basement of the work pit P through the filth discharge hose 1. When the discharge of the filth is completed, the discharge valve 3 is switched to the closed state, the connection fitting 9 is separated from the discharge valve 3 and washed, and then connected to the lid fitting 15 and stored again. At this time, in a state where the operation handle 11 of the connection fitting 9 is held with one hand and the handle 32 of the cover fitting 15 is held with the other hand, as shown in FIG. By temporarily latching 12 to the engagement guide edge 25 from above the lid fitting 15, the connection fitting 9 can be easily coupled to the lid fitting 15.

詳しくは、一対の係止体１２を係合案内縁２５に仮掛止した状態では、汚物排出ホース１および接続金具９の重みによって、接続金具９が係合案内縁２５に案内されて下降移動するので、作業者は下降する接続金具９の姿勢を矯正するだけで、両係止体１２を各対向側部２４に適正に係合できる。従って、蓋金具１５と接続金具９との連結を簡便に、しかも安全に行なうことができる。上記のように、接続金具９を蓋金具１５に再度連結した状態では、受光器１６ｂから制御部１８に対して検知信号が出力されるので、制御部１８は、汚物排出ホース１が蓋金具１５に連結された状態であると判定して警告具１７を消灯する。最後に、制御部１８の電源をオフ状態に切換えて、その蓋に設けたランプを消灯することにより、一連の作業を終了する。 Specifically, in a state where the pair of locking bodies 12 are temporarily hooked to the engagement guide edge 25, the connection fitting 9 is guided to the engagement guide edge 25 by the weight of the waste discharge hose 1 and the connection fitting 9, and moves downward. Therefore, the operator can properly engage both the locking bodies 12 with the opposing side portions 24 only by correcting the posture of the descending connection fitting 9. Accordingly, the lid metal 15 and the connection metal 9 can be easily and safely connected. As described above, since the detection signal is output from the light receiver 16b to the control unit 18 in the state in which the connection fitting 9 is connected to the lid fitting 15 again, the control unit 18 has the filth discharge hose 1 connected to the lid fitting 15. It is determined that the state is connected to the alarm device 17 and the warning device 17 is turned off. Finally, the power supply of the control unit 18 is switched to an off state, and the lamp provided on the lid is turned off to complete a series of operations.

上記構成の収納確認装置においては、吊持具２９で支持した蓋金具１５を、汚物排出ホース１の支持部材として利用し、接続金具９を蓋金具１５に連結して汚物排出ホース１を吊持した状態で収納するので、従来のこの種の装置に比べて、収納確認装置の全体構造を簡素化して全体コストを削減でき、収納確認装置の導入費用を低コスト化できる。さらにその設置に要するスペースを最小限化できるので、充分な広さが確保されていない作業ピットＰであっても、収納確認装置を容易に設置することができる。また、接続金具９に設けた一対の係止体１２を、蓋部２１の対向側部２４に対して相対的にスライド操作するだけで、接続金具９を蓋金具１５に連結し、あるいは、接続金具９を蓋金具１５から分離できるので、蓋金具１５と接続金具９との着脱を簡便に、しかも安全に行なうことができる。 In the storage confirmation device having the above configuration, the lid fitting 15 supported by the hanging tool 29 is used as a support member for the filth discharge hose 1, and the connection fitting 9 is connected to the lid fitting 15 to suspend the filth discharge hose 1. Therefore, the overall structure of the storage confirmation device can be simplified and the overall cost can be reduced, and the introduction cost of the storage confirmation device can be reduced as compared with the conventional device of this type. Furthermore, since the space required for the installation can be minimized, the storage confirmation device can be easily installed even if the work pit P is not sufficiently wide. Further, the connection fitting 9 is connected to the lid fitting 15 or connected only by sliding the pair of locking bodies 12 provided on the connection fitting 9 relative to the opposite side portion 24 of the lid portion 21. Since the metal fitting 9 can be separated from the lid metal fitting 15, the lid metal fitting 15 and the connection metal fitting 9 can be attached and detached simply and safely.

上記の実施例では、給排ホースが汚物排出ホース１である場合について説明したが、本発明の収納確認装置は、給排ホースが飲料水や、水洗トイレ用の洗浄水を供給する給水ホースである場合にも同様に適用することができる。警告具１７としては、回転警告灯、一定間隔おきに明滅する表示灯、警告音を同時に発生できる警告灯などの発光体を適用することができる。また、スピーカー、ブザーなどの発音体で警告具１７を構成することができる。受止部２２は部分円弧状の枠体で形成する必要はなく、蓋部２１の複数個所に固定した棒状体や突起、あるいは逆ハ字状に配置した板材などで形成することができ、要は、接続金具９の下部周面を支持できる構造であればよい。ガスケット２３は、接続金具９の金具端面１０に対応して無端環状に形成してあってもよい。 In the above embodiment, the case where the supply / discharge hose is the filth discharge hose 1 has been described. However, the storage confirmation device of the present invention is a supply hose that supplies drinking water or washing water for flush toilets. The same applies to some cases. As the warning device 17, a light emitter such as a rotating warning light, a display light that blinks at regular intervals, or a warning light that can simultaneously generate a warning sound can be applied. Further, the warning device 17 can be constituted by a sounding body such as a speaker or a buzzer. The receiving portion 22 does not need to be formed of a partially arc-shaped frame, but can be formed of a rod-like body or protrusion fixed at a plurality of positions of the lid portion 21 or a plate material arranged in an inverted C shape. Any structure that can support the lower peripheral surface of the connection fitting 9 may be used. The gasket 23 may be formed in an endless annular shape corresponding to the metal fitting end surface 10 of the connection metal fitting 9.

係合案内縁２５は、上すぼまり状に傾斜する一対の傾斜縁で形成することができる。検知部１６は、回帰反射型の光センサーユニットで構成する必要はなく、透過型の光センサーユニットで構成することができる。その場合には、投光器１６ａと受光器１６ｂを、接続金具９のフランジ壁を厚み方向へ挟む位置に配置し、そのいずれか一方をセンサーホルダー３１に配置するとよい。また、必要があれば、リミットスイッチ、近接スイッチ、リードスイッチなどのセンサーを検知要素にして検知部１６を構成することができる。 The engagement guide edge 25 can be formed of a pair of inclined edges that are inclined in a conical shape. The detection unit 16 does not need to be configured with a retroreflective optical sensor unit, but can be configured with a transmissive optical sensor unit. In that case, the light projector 16 a and the light receiver 16 b may be disposed at a position where the flange wall of the connection fitting 9 is sandwiched in the thickness direction, and one of them is disposed on the sensor holder 31. If necessary, the detection unit 16 can be configured using sensors such as limit switches, proximity switches, and reed switches as detection elements.

吊持具２９は、蓋金具１５を操作するときの自由度が高い点でチェーンが好ましいが、その必要はなく、ワイヤー、ベルト、ロープなどで吊持具２９を構成することができる。必要があれば、全方位方向へ揺動可能に支持した棒材や管材で吊持具２９を構成してもよい。また、吊持具２９および警告具１７は、キャットウォーク６の下面に配置する必要はなく、作業ピットＰに設けてある柱や支柱、あるいは電力ケーブルを支持するケーブルラック等を利用して設置することができる。蓋金具１５を引っ張りばねで上向きに移動付勢して、少なくとも蓋金具１５の重量を引っ張りばねのばね力で相殺して、接続金具９の着脱作業を補助することができる。 The suspension tool 29 is preferably a chain in that it has a high degree of freedom when operating the lid fitting 15, but it is not necessary, and the suspension tool 29 can be composed of a wire, a belt, a rope, or the like. If necessary, the suspending tool 29 may be formed of a bar or tube supported so as to be swingable in all directions. Further, the hanging tool 29 and the warning tool 17 do not need to be arranged on the lower surface of the catwalk 6, and are installed using a column or a column provided in the work pit P, a cable rack that supports the power cable, or the like. be able to. The lid fitting 15 can be moved and urged upward by the tension spring, and at least the weight of the lid fitting 15 can be offset by the spring force of the tension spring, so that the attaching / detaching operation of the connection fitting 9 can be assisted.

本発明の給排ホースの収納確認装置は、列車等の車両整備場において好適に使用できるが、長距離バスの車両整備場においても同様に使用できる。 The supply / discharge hose storage confirmation device of the present invention can be suitably used in a vehicle maintenance station such as a train, but can also be used in a long-distance bus vehicle maintenance station.
