Description

本発明の実施形態は、一対のばねによってカバーを器具本体に取り付ける照明装置に関する。 An embodiment of the present invention relates to a lighting device in which a cover is attached to a fixture body by a pair of springs.

従来、天井に設置された器具本体にこの器具本体を覆うカバーを取り付けるのに、一対のばねを用いた天井直付形または天井埋込形の照明装置がある。 Conventionally, there is a ceiling-mounted or ceiling-embedded lighting device using a pair of springs to attach a cover covering the fixture body to the fixture body installed on the ceiling.

この照明装置では、器具本体またはカバーのいずれか一方に取り付けた一対のばねを、他方に設けた一対のばね受部にそれぞれ係合させることにより、一対のばねのばね力によってカバーを器具本体に付勢し、カバーを器具本体に取り付けている。また、一対のばねのばね力に抗してカバーを器具本体から離反移動させることにより、器具本体を開放して作業することが可能となっている。 In this lighting device, a pair of springs attached to either the fixture body or the cover is engaged with a pair of spring receiving portions provided on the other, and the cover is attached to the fixture body by the spring force of the pair of springs. It is urged and the cover is attached to the instrument body. Further, by moving the cover away from the instrument body against the spring force of the pair of springs, the instrument body can be opened for work.

カバーを器具本体から離反移動させた際に、カバーが完全に外れる構成の場合、外れたカバーを床面に置いたり、床面に置かれたカバーを取って器具本体への取り付けを行わなければならず、作業性が悪い。そこで、ばね受部に引掛り部を設けることにより、カバーを器具本体から離反移動させた際に、ばねがばね受部の引掛り部に引っ掛かり、カバーを器具本体に仮吊りするようにしたものがある。 If the cover is completely removed when the cover is moved away from the instrument body, the removed cover must be placed on the floor or the cover placed on the floor must be removed and attached to the instrument body. The workability is poor. Therefore, by providing a hooking portion on the spring receiving portion, when the cover is moved away from the instrument body, the spring is caught on the hooking portion of the spring receiving portion and the cover is temporarily suspended from the instrument body. There is.

このような照明装置の多くは、同一形状の一対のばねを用いているとともに、同一形状の一対のばね受部を設けているか、あるいは、同一形状の一対のばねを用いているが、一対のばね受部のうち、一方は引掛り部がなく、他方のみに引掛り部があるというように、異なる形状の一対のばね受部を設けている。 Most of such lighting devices use a pair of springs having the same shape and provide a pair of spring receiving portions having the same shape, or use a pair of springs having the same shape. A pair of spring receiving portions having different shapes are provided, such that one of the spring receiving portions has no hooking portion and only the other has a hooking portion.

そして、一対のばね受部のうち、一方に引掛り部を設けず、他方のみに引掛り部を設けている場合には、カバーを器具本体から離反移動させた際、一方のばねとばね受部とが外れ、他方のばねとばね受部とが引っ掛かることで、カバーを器具本体に仮吊り状態とし、作業をよくすることが可能となっている。 When the hooking portion is not provided on one of the pair of spring receiving portions and the hooking portion is provided on only the other portion, when the cover is moved away from the instrument main body, one of the springs and the spring receiving portion is provided. When the part is disengaged and the other spring and the spring receiving part are caught, the cover is temporarily suspended from the instrument body, and the work can be improved.

しかしながら、ばね受部に引掛り部を設けている場合、カバーを器具本体に取り付ける作業時において、ばねをばね受部に挿入する際、引掛り部がばねの挿入の障害となって、作業性に支障が生じやすい。 However, when the spring receiving portion is provided with the hooking portion, the hooking portion becomes an obstacle to the insertion of the spring when the spring is inserted into the spring receiving portion during the work of attaching the cover to the instrument body, and the workability is improved. Is likely to cause problems.

図2において、カバー15をばね17a,17bの付勢に抗して引き下げる。カバー15を引き下げていくと、ばね17a,17bの係合部76にそれぞれ接触しているばね受部53a,53bによって、ばね17a,17bの両側部72の間隔が狭まるように弾性変形しながら、ばね受部53a,53bがばね17a,17bの突出部74の外側に移動する。 In FIG. 2, the cover 15 is pulled down against the urging of the springs 17a and 17b. As the cover 15 is pulled down, the spring receiving portions 53a and 53b, which are in contact with the engaging portions 76 of the springs 17a and 17b, respectively, elastically deform the springs 17a and 17b so that the distance between the side portions 72 is narrowed. The spring receiving portions 53a and 53b move to the outside of the protruding portions 74 of the springs 17a and 17b.

図3および図4に示すように、カバー15を器具本体11に対して所定の距離の位置(仮吊り位置)まで引き下げると、第1ばね受部53aが第1ばね17aの突出部74を乗り越えて下方に移動し、第1ばね受部53aが第1ばね17aの傾斜部77に接触し、第1ばね17aのばね力によって両側部72の間隔が広がりながら、第1ばね受部53aを下降させる。第1ばね受部53aは第1ばね17aの係止部79に当接して下降が規制され、第1ばね受部53aの内側に第1ばね17aの嵌り部78が嵌り込む。そのため、第1ばね受部53aは、第1ばね17aに対して下降が阻止された状態に保持される。 As shown in FIGS. 3 and 4, when the cover 15 is pulled down to a position (temporary suspension position) at a predetermined distance from the instrument body 11, the first spring receiving portion 53a gets over the protruding portion 74 of the first spring 17a. The first spring receiving portion 53a comes into contact with the inclined portion 77 of the first spring 17a, and the spring force of the first spring 17a widens the distance between the side portions 72 while lowering the first spring receiving portion 53a. Let me. The first spring receiving portion 53a abuts on the locking portion 79 of the first spring 17a to restrict its descent, and the fitting portion 78 of the first spring 17a fits inside the first spring receiving portion 53a. Therefore, the first spring receiving portion 53a is held in a state in which the lowering is prevented with respect to the first spring 17a.

このカバー15が器具本体11から所定の距離の位置(仮吊り位置)に離れた状態では、図5に示すように、第2ばね17bは、両側部72の間隔が狭まるように弾性変形した状態で、突出部74が第2ばね受部53bの内側に位置している。これは、距離A<距離Bの関係から、器具本体11の下面から第2ばね17bの突出部74までの距離Bが、器具本体11の下面から第1ばね17aの突出部74までの距離Aよりも大きいことによるものである。このように、第1ばね受部53aが第1ばね17aによって係止された位置で、第2ばね受部53bの内側に第2ばね17bの突出部74が位置していて、第2ばね受部53bが第2ばね17bのばね力によって上方または下方のいずれにも付勢されていない状態にあるため、カバー15が不用意に下降したり上昇することがない。 When the cover 15 is separated from the instrument main body 11 at a predetermined distance (temporary suspension position), as shown in FIG. 5, the second spring 17b is elastically deformed so that the distance between the side portions 72 is narrowed. The protruding portion 74 is located inside the second spring receiving portion 53b. This is because the distance B from the lower surface of the instrument body 11 to the protrusion 74 of the second spring 17b is the distance A from the lower surface of the instrument body 11 to the protrusion 74 of the first spring 17a because of the relationship of distance A <distance B. It is due to being larger than. In this way, at the position where the first spring receiving portion 53a is locked by the first spring 17a, the protruding portion 74 of the second spring 17b is located inside the second spring receiving portion 53b, and the second spring receiving portion 74b is located. Since the portion 53b is not urged either upward or downward by the spring force of the second spring 17b, the cover 15 does not inadvertently lower or rise.

さらに、カバー15が器具本体11から所定の距離の位置(仮吊り位置)に離れた状態から、カバー15を引き下げようとすると、第1ばね受部53aが第1ばね17aに係止されたカバー15の側部は下降が規制されるが、反対側の側部は下降し、第2ばね受部53bが第2ばね17bの突出部74を乗り越えて下方に移動し、第2ばね受部53bが第2ばね17bの挿入部75に接触し、第2ばね17bのばね力によって両側部72の間隔が広がりながら第2ばね受部53bを下降させる。 Further, when the cover 15 is pulled down from a state where the cover 15 is separated from the instrument main body 11 at a predetermined distance (temporary suspension position), the first spring receiving portion 53a is locked to the first spring 17a. The side portion of 15 is restricted from descending, but the side portion on the opposite side descends, the second spring receiving portion 53b moves downward over the protruding portion 74 of the second spring 17b, and the second spring receiving portion 53b Contact the insertion portion 75 of the second spring 17b, and the spring force of the second spring 17b lowers the second spring receiving portion 53b while widening the distance between the side portions 72.

図6に示すように、第2ばね受部53bが第2ばね17bから外れ、カバー15は第1ばね17aを介して斜めに吊下げられた状態となる。これにより、器具本体11の下面側が開口され、電池ユニット14が露出される。 As shown in FIG. 6, the second spring receiving portion 53b is disengaged from the second spring 17b, and the cover 15 is in a state of being obliquely suspended via the first spring 17a. As a result, the lower surface side of the instrument body 11 is opened, and the battery unit 14 is exposed.

したがって、カバー15は、器具本体11から完全に外れることがなく、第1ばね17aによって器具本体11に仮吊り状態にあるため、カバー15を床面に置くなどの作業が不要で、電池交換作業を容易に行うことができる。 Therefore, the cover 15 does not completely come off from the instrument body 11, and is temporarily suspended from the instrument body 11 by the first spring 17a. Therefore, it is not necessary to place the cover 15 on the floor, and the battery replacement work is performed. Can be easily performed.

そして、電池固定ばね39を外して電池部37を電池取付金具38から取り外し、電池部37と電源部33とのコネクタなどによる配線接続を解除した後、交換する新たな電池部37と電源部33とをコネクタなどによる配線接続し、その新たな電池部37を電池固定ばね39で電池取付金具38に固定する。このとき、電池ユニット14は、一対のばね17a,17bに対して交差する位置に配置されているため、電池部37の交換作業に一対のばね17a,17bが邪魔になるのを防止できる。 Then, the battery fixing spring 39 is removed, the battery unit 37 is removed from the battery mounting bracket 38, the wiring connection between the battery unit 37 and the power supply unit 33 is released, and then the new battery unit 37 and the power supply unit 33 are replaced. Is connected by wiring with a connector or the like, and the new battery unit 37 is fixed to the battery mounting bracket 38 with the battery fixing spring 39. At this time, since the battery unit 14 is arranged at a position intersecting the pair of springs 17a and 17b, it is possible to prevent the pair of springs 17a and 17b from interfering with the replacement work of the battery unit 37.

電池交換後は、第1ばね17aを支点としてカバー15を上方に回動させ、第2ばね受部53bの係合溝55を第2ばね17bの先端部71および挿入部75が挿入する。第2ばね受部53bが第2ばね17bの挿入部75に接触することにより、第2ばね17bは両側部72の間隔が狭まるように弾性変形しながら第2ばね受部53bの係合溝55に挿入される。 After replacing the battery, the cover 15 is rotated upward with the first spring 17a as a fulcrum, and the engaging groove 55 of the second spring receiving portion 53b is inserted into the tip portion 71 and the insertion portion 75 of the second spring 17b. When the second spring receiving portion 53b comes into contact with the insertion portion 75 of the second spring 17b, the second spring 17b is elastically deformed so as to narrow the distance between the side portions 72, and the engaging groove 55 of the second spring receiving portion 53b. Will be inserted into.

そして、上述した設置時と同様に、カバー15の全体を器具本体11に向けて押し上げると、第1ばね受部53aが第1ばね17aの傾斜部77に接触し、第1ばね17aは両側部72の間隔が狭まるように弾性変形しながら第1ばね受部53aの係合溝55に挿入されていく。 Then, as in the case of installation described above, when the entire cover 15 is pushed up toward the instrument body 11, the first spring receiving portion 53a comes into contact with the inclined portion 77 of the first spring 17a, and the first spring 17a is on both sides. It is inserted into the engaging groove 55 of the first spring receiving portion 53a while elastically deforming so that the distance between 72 is narrowed.

図2に示すように、カバー15の押し上げに伴って、第2ばね受部53bが第2ばね17bの突出部74を乗り越えて上方に移動し、その後、さらなるカバー15の押し上げに伴って、第1ばね受部53aが第1ばね17aの突出部74を乗り越えて上方に移動し、これらばね受部53a,53bがばね17a,17bの係合部76にそれぞれ接触する。ばね受部53a,53bがばね17a,17bの係合部76にそれぞれ接触することにより、ばね17a,17bのばね力によって両側部72の間隔が広がりながらばね受部53a,53bを上方に引き上げ、つまりカバー15を器具本体11に引き上げる。 As shown in FIG. 2, as the cover 15 is pushed up, the second spring receiving portion 53b moves upward over the protruding portion 74 of the second spring 17b, and then, as the cover 15 is pushed up further, the second spring receiving portion 53b moves upward. 1 The spring receiving portion 53a passes over the protruding portion 74 of the first spring 17a and moves upward, and these spring receiving portions 53a and 53b come into contact with the engaging portions 76 of the springs 17a and 17b, respectively. When the spring receiving portions 53a and 53b come into contact with the engaging portions 76 of the springs 17a and 17b, respectively, the spring forces of the springs 17a and 17b pull the spring receiving portions 53a and 53b upward while widening the distance between the side portions 72. That is, the cover 15 is pulled up to the instrument body 11.

ばね17a,17bによって器具本体11に引き寄せられるカバー15は、底面部42が本体ユニット12の下面に当接して止まる取付状態となり、ばね17a,17bの付勢によって取付状態に保持される。 The cover 15 attracted to the instrument main body 11 by the springs 17a and 17b is in an attached state in which the bottom surface portion 42 abuts on the lower surface of the main body unit 12 and stops, and is held in the attached state by the urging of the springs 17a and 17b.

以上のように、本実施形態の照明装置10によれば、一対のばね受部53a,53bは、同一形状とし、また、一対のばね17a,17bは、一方の第1ばね17aのみが係止部79を有する異なる形状とし、一対のばね受部53a,53bにそれぞれ係合されて、カバー15が器具本体11に取り付けられる状態にカバー15を器具本体11に付勢し、かつ、カバー15が器具本体11から所定の距離に離れる状態で、一方の第1ばね受部53aには係止部79が係止され、他方の第2ばね受部53bからは外れるため、設置時のカバー15の取付作業や電池交換時のカバー15の開閉作業の作業性を良好にできる。 As described above, according to the lighting device 10 of the present embodiment, the pair of spring receiving portions 53a and 53b have the same shape, and the pair of springs 17a and 17b are locked only by one of the first springs 17a. The cover 15 is urged to the instrument body 11 and the cover 15 is attached to the instrument body 11 so that the cover 15 is attached to the instrument body 11 by being engaged with a pair of spring receiving portions 53a and 53b, respectively, having different shapes having the portions 79. Since the locking portion 79 is locked to one of the first spring receiving portions 53a and disengaged from the other second spring receiving portion 53b while being separated from the instrument main body 11 by a predetermined distance, the cover 15 at the time of installation The workability of the cover 15 opening / closing work during installation work and battery replacement can be improved.

例えば、一対のばね受部53a,53bのいずれかにばね17a,17bの引掛り部を設けた場合、カバー15を器具本体11に取り付ける作業時において、ばね17a,17bをばね受部53a,53bに挿入する際、引掛り部がばね17a,17bの挿入の障害となって、作業性に支障が生じるが、第1ばね17aが係止部79を有することにより、ばね17a,17bをばね受部53a,53bに挿入する際の挿入の障害がなく、作業性を良好にできる。 For example, when the hooking portions of the springs 17a and 17b are provided on any of the pair of spring receiving portions 53a and 53b, the springs 17a and 17b are attached to the spring receiving portions 53a and 53b when the cover 15 is attached to the instrument body 11. When the spring 17a and 17b are inserted into the spring, the hooking portion hinders the insertion of the springs 17a and 17b, which hinders workability. There are no obstacles to insertion when inserting into parts 53a and 53b, and workability can be improved.

また、第1ばね17aが有する係止部79を突出部74と挿入部75との間に設けているため、カバー15を器具本体11から所定の距離まで離したときに、第1ばね17aによってカバー15を仮吊りすることができる。 Further, since the locking portion 79 of the first spring 17a is provided between the protruding portion 74 and the insertion portion 75, the first spring 17a causes the cover 15 to be separated from the instrument main body 11 to a predetermined distance. The cover 15 can be temporarily suspended.

また、係止部79は、嵌り部78の下端に連続する係止部79の内端側が、挿入部75の上端に連続する係止部79の外端側よりも下降するように傾斜されているため、第1ばね受部53aを確実に係止することができる。 Further, the locking portion 79 is inclined so that the inner end side of the locking portion 79 continuous with the lower end of the fitting portion 78 is lowered from the outer end side of the locking portion 79 continuous with the upper end of the insertion portion 75. Therefore, the first spring receiving portion 53a can be securely locked.

また、器具本体11の下面から第1ばね17aの突出部74までの距離Aは、器具本体11の下面から第2ばね17bの突出部74までの距離Bよりも小さい関係を有しているため、第1ばね受部53aが第1ばね17aによって係止された位置で、第2ばね受部53bの内側に第2ばね17bの突出部74が位置していて、第2ばね受部53bが第2ばね17bのばね力によって上方または下方のいずれにも付勢されていない状態にあるため、カバー15が不用意に下降したり上昇するのを防止できる。 Further, the distance A from the lower surface of the instrument body 11 to the protruding portion 74 of the first spring 17a has a smaller relationship than the distance B from the lower surface of the instrument body 11 to the projecting portion 74 of the second spring 17b. , The protruding portion 74 of the second spring 17b is located inside the second spring receiving portion 53b at the position where the first spring receiving portion 53a is locked by the first spring 17a, and the second spring receiving portion 53b is located. Since the second spring 17b is not urged either upward or downward by the spring force, it is possible to prevent the cover 15 from being inadvertently lowered or raised.

なお、本実施形態では、直付形の照明装置について説明したが、器具本体を天井面などの設置面に埋め込み設置する埋込形の照明装置にも適用することができる。この埋込形の照明装置の場合には、器具本体にばね受部を設け、器具本体の下面を覆うカバーにばねを取り付けてもよい。さらに、この場合、ばね受部は、ばね取付金具を別途用いるのではなく、器具本体に一体に設けてもよい。 Although the direct mounting type lighting device has been described in the present embodiment, it can also be applied to an embedded type lighting device in which the fixture main body is embedded in an installation surface such as a ceiling surface. In the case of this embedded lighting device, a spring receiving portion may be provided on the fixture body, and the spring may be attached to a cover covering the lower surface of the fixture body. Further, in this case, the spring receiving portion may be provided integrally with the instrument main body instead of using the spring mounting bracket separately.
