The lens part 220 of the light source unit 2 is inserted through the window hole 50. The cover 5 is configured to openably close an opening on the front surface of the main body 1. At the front and rear ends of the upper surface of the cover 5, mounting springs 7 are respectively mounted. The pair of mounting springs 7 are removably inserted into insertion grooves 13 provided on a pair of front and rear sides of the inner peripheral surface of the main body 1. That is, the cover 5 is held by the main body 1 in a state where the lower surface of the main body 1 is closed by the pair of mounting springs 7 being inserted through the pair of insertion grooves 13 (see FIG. 2C).

一対の挿通溝13は、本体1の内周面と、本体1の内周面から内側に突出する一対の引掛部130とで構成される(図3参照)。一対の引掛部130は、それぞれ上下方向から見てL字形状に形成されることが好ましい。また、一対の引掛部130は、互いの開口部分を前後方向に対向させるように配置される(図3参照)。また、本体1の内周面における一対の引掛部130の下方には、仮保持部15がそれぞれ設けられる(図3、図7A及び図7B参照)。これらの仮保持部15は、前後方向から見てL字形状に形成されることが好ましい。なお、一対の引掛部130及び仮保持部15は、図3に示すように、本体1の内周面において、電池ユニット3と点灯ユニット4が本体1内で並ぶ方向(左右方向)と交差する方向(例えば、前後方向)の両側にそれぞれ配置される。   The pair of insertion grooves 13 includes an inner peripheral surface of the main body 1 and a pair of hooks 130 projecting inward from the inner peripheral surface of the main body 1 (see FIG. 3). It is preferable that each of the pair of hooks 130 is formed in an L-shape when viewed from above and below.

These temporary holding portions 15 are preferably formed in an L-shape when viewed from the front-back direction. As shown in FIG. 3, the pair of hook portions 130 and the temporary holding portions 15 intersect with the direction in which the battery unit 3 and the lighting unit 4 are arranged in the main body 1 (lateral direction) on the inner peripheral surface of the main body 1.

In addition, the mounting spring 7 is configured so that the distance d1 between the projecting portions 72 of the pair of spring portions 70 is larger than the distance d2 between the pair of hook portions 130 (see FIG. 7A). Furthermore, the mounting spring 7 is configured so that the distance d3 from the lower end of the spring portion 70 to the projecting portion 72 is longer than the distance d4 from the hook portion 130 to the lower end of the main body 1 (see FIG. 7B).

次に、本実施形態に係る非常用照明装置Xの組立手順を説明する。ただし、一対の支持具6は、既に本体1に取り付けられている。   Next, an assembly procedure of the emergency lighting device X according to the present embodiment will be described. However, the pair of supports 6 is already attached to the main body 1.

まず、組立作業を行う作業者は、本体1内に点灯ユニット4を収容し、本体1の底板11の固定片110に点灯ユニット4の筐体41をねじ止めして固定する(図1参照)。それから、作業者は、光源ユニット2を点灯ユニット4の筐体41に取り付ける。ここで、筐体41の下面には、放熱部材21の2つの丸孔2110にそれぞれ個別に挿通される2つの突起411が下向きに突設されている。つまり、作業者は、放熱部材21の固定部211に設けられている2つの丸孔2110に2つの突起411を個別に挿通させて位置決めするようにして、固定部211を筐体41の下面に載せる。ただし、作業者は、本体1の被固定部12が放熱部材21の下になるように、被固定部12と筐体41の下面との間に固定部211を挿入する(図3参照)。それから、作業者は、被固定部12のねじ挿通孔120に挿通したねじを、放熱部材21の固定部211に設けられている第1ねじ孔2111にねじ込むことにより、光源ユニット2を点灯ユニット4の筐体41に取り付ける(図3参照)。このとき、光源ユニット2のプラグコネクタ26は、筐体41の中央の開口部410Bの奥に配置されているレセプタクルコネクタ408と電気的かつ機械的に接続される。なお、固定部211には、丸孔2110の代わりに、突起411が嵌まる凹部が設けられても構わない。   First, a worker who performs an assembling operation accommodates the lighting unit 4 in the main body 1 and fixes the casing 41 of the lighting unit 4 to the fixing piece 110 of the bottom plate 11 of the main body 1 by screwing (see FIG. 1). . Then, the worker attaches the light source unit 2 to the housing 41 of the lighting unit 4. Here, on the lower surface of the housing 41, two projections 411 that are individually inserted into the two round holes 2110 of the heat radiation member 21 are provided to project downward. That is, the operator positions the fixing portion 211 on the lower surface of the housing 41 by positioning the two protrusions 411 by individually inserting the two protrusions 411 into the two round holes 2110 provided in the fixing portion 211 of the heat radiation member 21. Put on. However, the worker inserts the fixing portion 211 between the fixed portion 12 and the lower surface of the housing 41 so that the fixed portion 12 of the main body 1 is below the heat radiating member 21 (see FIG. 3). Then, the operator turns the light source unit 2 into the lighting unit 4 by screwing the screw inserted into the screw insertion hole 120 of the fixed portion 12 into the first screw hole 2111 provided in the fixing portion 211 of the heat radiation member 21. (See FIG. 3). At this time, the plug connector 26 of the light source unit 2 is electrically and mechanically connected to the receptacle connector 408 disposed behind the central opening 410B of the housing 41. Note that, instead of the round hole 2110, a concave portion into which the projection 411 fits may be provided in the fixing portion 211.

続いて、作業者は、本体1内に電池ユニット3を収容する。電池ユニット3のコネクタ部32は、電池ユニット3が本体1内に収容される際に、点灯ユニット4の筐体41に設けられている開口部410Aを通して、点灯ユニット4の受け側のコネクタと電気的かつ機械的に接続される。ここで、筐体41の右側面の後端寄りの部位には、凹部412が設けられている(図4参照)。そして、電池ユニット3の抜け止め部33の突起331が筐体41の凹部412に引っ掛かることにより、電池ユニット3が点灯ユニット4の筐体41に取り付けられる。なお、作業者は、抜け止め部33のばね片330を指で摘まんで撓ませ、突起331と凹部412の引っ掛かりを解除することにより、光源ユニット2が点灯ユニット4の筐体41に取り付けられた状態で本体1から電池ユニット3を引き抜いて取り外すことができる。   Subsequently, the worker accommodates the battery unit 3 in the main body 1. When the battery unit 3 is housed in the main body 1, the connector unit 32 of the battery unit 3 communicates with the connector on the receiving side of the lighting unit 4 through the opening 410 </ b> A provided in the housing 41 of the lighting unit 4. And mechanically connected. Here, a recess 412 is provided in a portion near the rear end of the right side surface of the housing 41 (see FIG. 4). Then, the projection 331 of the retaining portion 33 of the battery unit 3 is hooked on the concave portion 412 of the housing 41, so that the battery unit 3 is attached to the housing 41 of the lighting unit 4. The light source unit 2 was attached to the housing 41 of the lighting unit 4 by releasing the hook between the protrusion 331 and the concave portion 412 by pinching and bending the spring piece 330 of the retaining portion 33 with a finger. In this state, the battery unit 3 can be removed from the main body 1 by pulling it out.

最後に、作業者は、一対の取付ばね7を本体1の内周面の前側及び後側にそれぞれ一対ずつ設けられる挿通溝13に挿通することにより、本体1の下面を閉塞するようにカバー5を本体1に保持させる(図2C及び図7A参照)。以上のようにして、本実施形態に係る非常用照明装置Xの組立が完了する。   Finally, the operator inserts the pair of mounting springs 7 into the insertion grooves 13 provided on the front and rear sides of the inner peripheral surface of the main body 1, respectively, so that the lower surface of the main body 1 is closed. Is held by the main body 1 (see FIGS. 2C and 7A). As described above, the assembly of the emergency lighting device X according to the present embodiment is completed.

続いて、本実施形態に係る非常用照明装置Xの電池ユニット3の交換作業の手順を説明する。   Next, a procedure for replacing the battery unit 3 of the emergency lighting device X according to the present embodiment will be described.

交換作業を行う作業者は、取付ばね7のばね力に抗してカバー5を下向きに引っ張る。カバー5が下向きに引っ張られると、取付ばね7は、一対のばね部70を互いに近付く向きに撓ませながら挿通溝13内を下向きに移動し、連結部71が仮保持部15に当たる位置(仮保持位置)で停止する(図7B参照)。ここで、作業者がカバー5を下向きに引っ張ったとき、引掛部130が取付ばね7のばね部70から下向きの応力を受けるため、本体1も下向きに引っ張られることになる。しかしながら、本体1が下向きの力を受ける場所(引掛部130)は、本体1を天井に対して支持している支持具6の固定場所から、水平面内において最も遠い位置にある。そのため、作業者がカバー5を下向きに引っ張った際、埋込孔から本体1が抜けるほど支持具6が撓む可能性は極めて低い。   The operator performing the replacement work pulls the cover 5 downward against the spring force of the mounting spring 7. When the cover 5 is pulled downward, the mounting spring 7 moves downward in the insertion groove 13 while bending the pair of spring portions 70 toward each other, and the connecting portion 71 contacts the temporary holding portion 15 (temporary holding position). Position) (see FIG. 7B). Here, when the worker pulls the cover 5 downward, the hook portion 130 receives a downward stress from the spring portion 70 of the mounting spring 7, so that the main body 1 is also pulled downward. However, the place where the main body 1 receives the downward force (the hook portion 130) is located farthest in the horizontal plane from the place where the support 6 that supports the main body 1 with respect to the ceiling is fixed. For this reason, when the operator pulls the cover 5 downward, the possibility that the support 6 bends as the main body 1 comes out of the embedding hole is extremely low.

そして、作業者は、一対の取付ばね7の連結部71をそれぞれ仮保持部15から外してカバー5を取り外した後、抜け止め部33のばね片330を指で摘まんで突起331と凹部412の引っ掛かりを解除した状態で本体1から電池ユニット3を引き抜く。それから、作業者は、新しい電池ユニット3を本体1内に収容した後、再び取付ばね7を挿通溝13に挿通し、下から押し上げるようにしてカバー5を本体1の下面側に取り付ける。以上のようにして、電池ユニット3の交換作業が完了する。   Then, the operator removes the cover 5 by detaching the connecting portions 71 of the pair of mounting springs 7 from the temporary holding portions 15, and then grips the spring pieces 330 of the retaining portions 33 with fingers to form the protrusions 331 and the concave portions 412. The battery unit 3 is pulled out of the main body 1 in a state where the hook is released. Then, after accommodating the new battery unit 3 in the main body 1, the operator again inserts the mounting spring 7 into the insertion groove 13 and attaches the cover 5 to the lower surface side of the main body 1 by pushing up from below. The replacement of the battery unit 3 is completed as described above.

ところで、電池ユニット3の抜け止め部33に何らかの不具合等が生じた場合、作業者がカバー5を引き下げたときに電池ユニット3が本体1から抜け落ちてしまう可能性がある。そこで、本実施形態に係る非常用照明装置Xは、取付ばね7の連結部71が本体1の仮保持部15に仮保持されている状態において、本体1の下面からカバー5の上面までの距離d5が、電池ケース31の高さH1よりも短くなるように構成されることが好ましい。具体的には、図8に示すように、本体1の内周面において、上記条件(d5<H1)を満たす高さ位置に仮保持部15が設けられることが好ましい。つまり、カバー5が引き下げられたときに電池ユニット3が本体1から抜けたとしても、取付ばね7が本体1の仮保持部15に仮保持されていれば、電池ユニット3がカバー5よりも下に落下することを防止できる。   By the way, when any trouble or the like occurs in the retaining portion 33 of the battery unit 3, there is a possibility that the battery unit 3 falls off from the main body 1 when the operator pulls down the cover 5. Therefore, in the emergency lighting device X according to the present embodiment, the distance from the lower surface of the main body 1 to the upper surface of the cover 5 when the connecting portion 71 of the mounting spring 7 is temporarily held by the temporary holding portion 15 of the main body 1.

Specifically, as shown in FIG. 8, it is preferable that the temporary holding portion 15 is provided at a height position on the inner peripheral surface of the main body 1 that satisfies the above condition (d5 <H1). In other words, even if the battery unit 3 comes off from the main body 1 when the cover 5 is pulled down, if the mounting spring 7 is temporarily held by the temporary holding portion 15 of the main body 1, the battery unit 3 becomes lower than the cover 5. Can be prevented from falling.

上述のように本実施形態に係る非常用照明装置Xは、本体1と、光源ユニット2と、電池ユニット3と、点灯ユニット4と、カバー5と、一対の支持具6と、1つ又は複数の取付ばね7とを備える。本体1は、前面が開口した有底筒状に形成される。電池ユニット3は、電池30と、電池30を収容する電池ケース31とを有する。点灯ユニット4は、電池30から供給される電力で光源ユニット2を点灯させる点灯装置40と、点灯装置40を収容する筐体41とを有する。光源ユニット2は、筐体41の前面に取り付けられる。カバー5は、光源ユニット2から放射される光が通過する窓孔50を有し、本体1の前面の開口を開放可能に塞ぐように構成される。電池ケース31は、(本体1の)開口を通して本体1内に抜き差し可能に挿入される。支持具6は、長尺の板ばね状に形成され、長手方向の一端部で本体1の外周面に固定され、かつ、長手方向の他端部が本体1の底(底板11)に近付く向きに撓み可能に構成される。取付ばね7は、U字状に形成されて両側のばね部70の先端がカバー5に取着され、両側のばね部70の中間部位(突出部位72)が互いに離間する方向へ突出するような形状に形成された線ばねで構成される。本体1は、電池ユニット3と点灯ユニット4を前面と並行して並べるように収容し、電池ユニット3及び点灯ユニット4を挟んで対向する外周面の両側に、一対の支持具6の一端部がそれぞれ固定される。本体1は、さらに、電池ユニット3と点灯ユニット4が並ぶ方向と交差する方向に沿って対向する内周面の両側若しくは片側に、挿通溝13と、一対の引掛部130と、仮保持部15とを有する。挿通溝13は、取付ばね7が抜き差し可能に挿通される。一対の引掛部130は、カバー5が(本体1の)開口を塞いでいる状態で取付ばね7の両側のばね部70の突出部位72にそれぞれ引っ掛かる。仮保持部15は、カバー5が(本体1の)開口を開放している状態で取付ばね7の中央部(連結部71)が引っ掛かって保持される。   As described above, the emergency lighting device X according to the present embodiment includes the main body 1, the light source unit 2, the battery unit 3, the lighting unit 4, the cover 5, the pair of supports 6, one or more And a mounting spring 7. The main body 1 is formed in a bottomed cylindrical shape with an open front surface. The battery unit 3 has a battery 30 and a battery case 31 that houses the battery 30. The lighting unit 4 includes a lighting device 40 for lighting the light source unit 2 with electric power supplied from the battery 30, and a housing 41 that houses the lighting device 40. The light source unit 2 is attached to a front surface of the housing 41. The cover 5 has a window 50 through which light emitted from the light source unit 2 passes, and is configured to openably close an opening on the front surface of the main body 1. The battery case 31 is removably inserted into the main body 1 through an opening (of the main body 1). The support 6 is formed in the shape of a long plate spring, and is fixed to the outer peripheral surface of the main body 1 at one end in the longitudinal direction, and the other end in the longitudinal direction approaches the bottom (bottom plate 11) of the main body 1. It is configured to be able to bend. The mounting spring 7 is formed in a U-shape so that the distal ends of the spring portions 70 on both sides are attached to the cover 5, and the intermediate portions (projection portions 72) of the spring portions 70 on both sides project in a direction away from each other.

本実施形態に係る非常用照明装置Xは上述のように構成されるので、従来例のようにカバー5が本体1にねじ止めされる構成と比較して、組立作業の簡略化を図ることができる。また、本実施形態に係る非常用照明装置Xは、本体1に対する一対の支持具6の固定位置と、本体1に対する取付ばね7の取付位置とが、本体1前面の法線方向(上下方向)からみて最も離れた位置関係となる。そのため、本実施形態に係る非常用照明装置Xは、カバー5が引き下げられる際に一対の支持具6に加わる応力が低減されるから、支持具6による本体1の支持が解除される可能性を極めて低くすることができる。さらに、本実施形態に係る非常用照明装置Xは、本体1内に収容される電池ユニット3及び点灯ユニット4の近くに一対の支持具6を各別に配置するので、重量の大きい電池ユニット3及び点灯ユニット4を確実に支持することができる。   Since the emergency lighting device X according to the present embodiment is configured as described above, the assembling work can be simplified as compared with a configuration in which the cover 5 is screwed to the main body 1 as in the conventional example. it can. Also, in the emergency lighting device X according to the present embodiment, the fixing position of the pair of supports 6 with respect to the main body 1 and the mounting position of the mounting spring 7 with respect to the main body 1 are in the normal direction of the front surface of the main body 1 (vertical direction). It is the most distant positional relationship. For this reason, in the emergency lighting device X according to the present embodiment, since the stress applied to the pair of supports 6 when the cover 5 is pulled down is reduced, there is a possibility that the support of the main body 1 by the supports 6 is released. It can be very low. Further, in the emergency lighting device X according to the present embodiment, since the pair of supports 6 are separately arranged near the battery unit 3 and the lighting unit 4 housed in the main body 1, the heavy battery unit 3 and the The lighting unit 4 can be reliably supported.

また、本実施形態に係る非常用照明装置Xにおいて、取付ばね7は、連結部71が仮保持部15に保持されている状態において、本体1の前端からカバー5までの距離d5を、電池ケース31の本体1の奥行き方向(上下方向)に沿った高さH1よりも短くするように構成されることが好ましい。   Further, in the emergency lighting device X according to the present embodiment, the mounting spring 7 sets the distance d5 from the front end of the main body 1 to the cover 5 in a state where the connecting portion 71 is held by the temporary holding portion 15 to the battery case. It is preferable that the height of the main body 1 be shorter than the height H1 of the main body 1 along the depth direction (vertical direction).

本実施形態に係る非常用照明装置Xが上述のように構成されれば、カバー5が引き下げられたときに電池ユニット3が本体1から抜けたとしても、電池ユニット3をカバー5で受け止めて落下することを防止できる。   If the emergency lighting device X according to the present embodiment is configured as described above, even if the battery unit 3 comes off from the main body 1 when the cover 5 is pulled down, the battery unit 3 is received by the cover 5 and falls.

ところで、本実施形態に係る非常用照明装置Xにおいて、取付ばね7は必ずしも2つ用いられなくてもよい。例えば、図9及び図10に示すように、1つの取付ばね7と、1つの係合部52とがカバー5に設けられてもよい。ただし、本体1には、図11に示すように係合部52が係合される被係合部16が設けられる。つまり、係合部52と被係合部16とで、いわゆるラッチを構成している。   By the way, in the emergency lighting device X according to the present embodiment, two mounting springs 7 need not always be used. For example, as shown in FIGS. 9 and 10, one mounting spring 7 and one engaging portion 52 may be provided on the cover 5. However, the main body 1 is provided with the engaged portion 16 with which the engaging portion 52 is engaged as shown in FIG. That is, the engagement portion 52 and the engaged portion 16 constitute a so-called latch.

係合部52は、いわゆるストライカーであって、金属材料又は合成樹脂材料によって、先端部分が角筒状に形成される(図9及び図11参照)。被係合部16は、いわゆるキャッチであって、係合部52(ストライカー)と同種の材料(金属材料又は合成樹脂材料)によって、一対のばね片160と、連結片161とが一体に形成されて構成される。一対のばね片160は、先端(下端)が略U字形状に湾曲し、後端(上端)が連結片161と連結されるように構成される(図11参照)。連結片161は、一対のばね片160の湾曲した部位同士を対向させるように、これら一対のばね片160の後端に連結される。係合部52は、一対のばね片160の間に先端(下端)側から挿入され、一対のばね片160を互いに離れる向きに撓ませながら上に移動し、最終的に一対のばね片160の先端部分(湾曲した部分)と係合する(図11参照)。また、係合部52は、カバー5が引き下げられると、一対のばね片160を撓ませながら下向きに移動し、最終的に一対のばね片160の先端部分を乗り越えて被係合部16との係合が解除される。   The engaging portion 52 is a so-called striker, and its distal end portion is formed in a square tubular shape using a metal material or a synthetic resin material (see FIGS. 9 and 11). The engaged portion 16 is a so-called catch, and a pair of spring pieces 160 and a connecting piece 161 are integrally formed of the same type of material (metal material or synthetic resin material) as the engaging portion 52 (striker). It is composed. The pair of spring pieces 160 are configured such that the front ends (lower ends) are curved in a substantially U-shape, and the rear ends (upper ends) are connected to the connection pieces 161 (see FIG. 11). The connecting piece 161 is connected to the rear ends of the pair of spring pieces 160 so that the curved portions of the pair of spring pieces 160 face each other. The engaging portion 52 is inserted between the pair of spring pieces 160 from the tip (lower end) side, moves upward while bending the pair of spring pieces 160 away from each other, and finally moves the pair of spring pieces 160. Engage with the tip portion (curved portion) (see FIG. 11). Further, when the cover 5 is pulled down, the engaging portion 52 moves downward while bending the pair of spring pieces 160, and finally rides over the distal end portions of the pair of spring pieces 160, and engages with the engaged portion 16. The engagement is released.

本実施形態に係る非常用照明装置Xが上述のように構成された場合、カバー5が引き下げられたときに電池ユニット3が本体1から抜けたとしても、電池ユニット3がカバー5よりも下に落下することを防止できる。つまり、取付ばね7が本体1の仮保持部15に仮保持されていれば、例え係合部52が被係合部16から外れたとしても、電池ユニット3が本体1から完全に抜けることを回避できる(図9及び図10参照)。また、本実施形態に係る非常用照明装置Xが上述のように構成された場合、取付ばね7が2つ用いられる場合と比較して、本体1に対するカバー5の取付・取り外し作業の更なる簡略化を図ることができる。   When the emergency lighting device X according to the present embodiment is configured as described above, even if the battery unit 3 is detached from the main body 1 when the cover 5 is pulled down, the battery unit 3 is positioned below the cover 5. Falling can be prevented. That is, if the mounting spring 7 is temporarily held by the temporary holding portion 15 of the main body 1, even if the engaging portion 52 is disengaged from the engaged portion 16, the battery unit 3 is completely removed from the main body 1. This can be avoided (see FIGS. 9 and 10). Further, when the emergency lighting device X according to the present embodiment is configured as described above, the work of attaching and detaching the cover 5 to and from the main body 1 is further simplified as compared with the case where two attachment springs 7 are used. Can be achieved.

本実施形態に係る非常用照明装置Xにおいて、カバー5は、1つの取付ばね7が取着されている部位と窓孔50を挟んで反対側の部位に係合部52が設けられることが好ましい。本体1は、電池ユニット3及び点灯ユニット4を挟んで一対の引掛部130と対向する内周面に、係合部52が着脱可能に係合する被係合部16が設けられることが好ましい。   In the emergency lighting device X according to the present embodiment, it is preferable that the cover 5 is provided with the engaging portion 52 at a portion opposite to the portion where the one attachment spring 7 is attached and across the window hole 50. . It is preferable that the main body 1 is provided with an engaged portion 16 with which the engaging portion 52 is detachably engaged on an inner peripheral surface facing the pair of hook portions 130 with the battery unit 3 and the lighting unit 4 interposed therebetween.

本実施形態に係る非常用照明装置Xが上述のように構成されれば、電池ユニット3の落下を防止しつつ、組立作業の更なる簡略化を図ることができる。   If the emergency lighting device X according to the present embodiment is configured as described above, the assembly operation can be further simplified while preventing the battery unit 3 from dropping.
