Description

本発明は、光源を有する灯具にセードを取付けた照明装置に関するものである。   The present invention relates to an illumination device in which a shade is attached to a lamp having a light source.

図７に示すように、従来の照明装置１００は、灯具本体１０２の開口に、前面にセードを兼ねたガラス１０１ａを有するランプ１０１を取付けている。この際、全体Ｃ字形状をしたバネ１０３を灯具本体１０２の開口に取付けて、ランプ１０１の脱落を防止している（例えば特許文献１参照）。   As shown in FIG. 7, in the conventional lighting device 100, a lamp 101 having a glass 101 a serving as a shade on the front surface is attached to an opening of a lamp body 102. At this time, an overall C-shaped spring 103 is attached to the opening of the lamp body 102 to prevent the lamp 101 from falling off (see, for example, Patent Document 1).

すなわち、ランプ１０１を灯具本体１０２の内部に収納し、ランプ１０１のつば部１０１ｂをバネ１０３により押え、バネ１０３に設けられている凸部１０３ａを灯具本体１０２に設けられている係止孔１０２ａに挿嵌して、ランプ１０１を灯具本体１０２の内部に取付けている。   That is, the lamp 101 is housed inside the lamp body 102, the collar portion 101b of the lamp 101 is pressed by the spring 103, and the projection 103a provided on the spring 103 is inserted into the locking hole 102a provided on the lamp body 102. The lamp 101 is attached inside the lamp body 102 by being inserted.

しかしながら、前述した照明装置１００の構成では、バネ１０３が灯具本体１０２から脱落すると直ちにランプ１０１が落下することになり、外れやすいという問題があった。また、バネ１０３が見える位置に取付けられているため、外観が悪いという問題があった。
このため、近年、灯具本体に対してセードを回転させて取付ける照明装置が用いられるようになってきた（例えば特許文献２参照）。
実開昭６１−１４２３０２号公報（第１図） 特開２００１−２１６８３０号公報 However, in the configuration of the lighting device 100 described above, there is a problem that when the spring 103 is detached from the lamp body 102, the lamp 101 is immediately dropped and is easily detached. Further, since the spring 103 is attached at a position where it can be seen, there is a problem that the appearance is poor.
For this reason, in recent years, an illumination device has been used in which a shade is rotated and attached to a lamp body (see, for example, Patent Document 2).
Japanese Utility Model Publication No. 61-142302 (FIG. 1) JP 2001-216830 A

しかしながら、特許文献２に記載の照明装置においては、灯具本体に対してセードを回転させて取付ける構造ではあるが、取付状態においてセードが灯具本体に対して回転して緩むことがあり、セードの脱落を確実に防止できないという問題があった。   However, the lighting device described in Patent Document 2 has a structure in which the shade is rotated and attached to the lamp body. However, in the attached state, the shade may rotate and loosen with respect to the lamp body, and the shade may fall off. There was a problem that could not be reliably prevented.

本発明は、従来の問題を解決するためになされたものであり、簡単な構造により確実にセードの脱落を防止することができる照明装置を提供することを目的とする。   The present invention has been made to solve the conventional problems, and an object of the present invention is to provide an illuminating device that can reliably prevent the fall of the shade with a simple structure.

本発明の照明装置は、灯具の円形の取付部とセードの円形の取付部の一方に設けられた嵌合溝に他方に設けられた嵌合突起を嵌合させ回転させて取付ける照明装置であって、前記嵌合溝に全体略Ｃ字形状を有するとともにＣ字形状の内側または外側に突出する突出部を有するバネ部材を設けた構成を有している。   The lighting device of the present invention is a lighting device in which a fitting protrusion provided on the other is fitted into a fitting groove provided on one of the circular mounting portion of the lamp and the circular mounting portion of the shade, and is mounted by rotating. In addition, the fitting groove has a substantially C-shape as a whole and a spring member having a protruding portion protruding inward or outward of the C-shape.

この構成により、灯具の円形の取付部とセードの円形の取付部の一方に設けられた嵌合溝に、他方に設けられた嵌合突起を嵌合させ回転させることにより、セードを灯具に取付ける。このとき、嵌合突起がバネ部材の突出部を乗り越えるまでセードを相対的に回転させる。これにより、セードが灯具に対して緩む方向へ回転しようとしても一定以上の力で回転させなければバネ部材の突出部を乗り越えることができないので、外れるのを確実に防止することができる。   With this configuration, the shade is attached to the lamp by fitting and rotating the fitting protrusion provided in the other into the fitting groove provided in one of the circular attachment portion of the lamp and the circular attachment portion of the shade. . At this time, the shade is relatively rotated until the fitting protrusion gets over the protruding portion of the spring member. As a result, even if the shade is about to rotate relative to the lamp, the protrusion of the spring member cannot be overcome unless it is rotated with a certain force or more, so that it can be reliably prevented from coming off.

また、本発明の照明装置は、前記灯具の取付部の外周面に前記嵌合溝を設けるとともに、前記セードの取付部の内周面に前記嵌合突起を設け、かつ前記バネ部材の突出部を外側へ突出させて設けた構成を有している。   In the lighting device of the present invention, the fitting groove is provided on the outer peripheral surface of the attachment portion of the lamp, the fitting protrusion is provided on the inner peripheral surface of the attachment portion of the shade, and the protruding portion of the spring member It has the structure which protruded to the outer side.

この構成により、灯具の取付部の外周面に設けられた嵌合溝に、セードの取付部の内周面に設けられた嵌合突起を嵌合させ回転させてセードを灯具に取付ける。この際、セードの嵌合突起が嵌合溝に設けられているバネ部材の突出部を乗り越えるように取付けることにより、外れるのを確実に防止することができる。   According to this configuration, the fitting protrusion provided on the inner peripheral surface of the attachment portion of the shade is fitted in the fitting groove provided on the outer peripheral surface of the attachment portion of the lamp, and the shade is attached to the lamp. At this time, it is possible to reliably prevent the fitting protrusion of the shade from coming off by mounting it so as to get over the protruding portion of the spring member provided in the fitting groove.

さらに、本発明の照明装置は、前記バネ部材の突出部を、該バネ部材における前記嵌合突起の取付時回転方向終端の近傍に設けた構成を有している。   Furthermore, the lighting device of the present invention has a configuration in which the protruding portion of the spring member is provided in the vicinity of the end in the rotational direction when the fitting protrusion is attached to the spring member.

この構成により、バネ部材の弾性を有効に活用することができ、良好な取付感が得られる。   With this configuration, the elasticity of the spring member can be effectively utilized, and a good mounting feeling can be obtained.

さらに、本発明の照明装置は、前記バネ部材の少なくとも一端を前記嵌合溝に設けたストッパによって係止する構成を有している。   Furthermore, the lighting device of the present invention has a configuration in which at least one end of the spring member is locked by a stopper provided in the fitting groove.

この構成により、嵌合突起がバネ部材の突出部を乗り越える際に、バネ部材が嵌合溝に対してずれるのを防止することができる。   With this configuration, the spring member can be prevented from shifting with respect to the fitting groove when the fitting protrusion gets over the protruding portion of the spring member.

本発明は、灯具の円形の取付部とセードの円形の取付部の一方に設けられた嵌合溝に、他方に設けられた嵌合突起を嵌合させ回転させることにより、セードを灯具に取付ける。このとき、嵌合突起がバネ部材の突出部を乗り越えるまでセードを相対的に回転させる。これにより、セードが灯具に対して緩む方向へ回転しようとしても一定以上の力で回転させなければバネ部材の突出部を乗り越えることができないので、外れるのを確実に防止することができるという効果を有する照明装置を提供することができるものである。   The present invention attaches a shade to a lamp by fitting and rotating a fitting protrusion provided on the other into a fitting groove provided on one of the circular attachment part of the lamp and the circular attachment part of the shade. . At this time, the shade is relatively rotated until the fitting protrusion gets over the protruding portion of the spring member. As a result, even if the shade does not rotate with respect to the lamp in the direction of loosening, the protrusion of the spring member cannot be overcome unless it is rotated with a certain force or more, so that it can be reliably prevented from coming off. It is possible to provide a lighting device having the same.

以下、本発明の実施の形態の照明装置について、図面を用いて説明する。

FIG. 6B is a perspective view showing a state after the fitting protrusion of the shade has passed over the protruding portion of the spring member.

図１に示すように、本発明の照明装置１０は、光源であるランプ２１を内部に有する灯具２０と、灯具２０の照明方向前部に取付けられるセード３０を有している。灯具２０とセード３０は、灯具２０の円形の取付部２２とセード３０の円形の取付部３１の一方（ここでは灯具２０の取付部２２）に設けられた嵌合溝２３に、他方（ここではセード３０の取付部３１）に設けられた嵌合突起３２を嵌合させ回転させて、着脱可能に取付けるようになっている。そして、嵌合溝２３に全体略Ｃ字形状を有するとともにＣ字形状の内側または外側に突出する突出部４１を有するバネ部材４０が設けられている。   As shown in FIG. 1, the illuminating device 10 of this invention has the lamp 20 which has the lamp | ramp 21 which is a light source inside, and the shade 30 attached to the illumination direction front part of the lamp | ramp 20. As shown in FIG. The lamp 20 and the shade 30 are provided in the fitting groove 23 provided in one of the circular mounting portion 22 of the lamp 20 and the circular mounting portion 31 of the shade 30 (here, the mounting portion 22 of the lamp 20), and the other (here, The fitting protrusion 32 provided on the attachment portion 31) of the shade 30 is fitted and rotated so as to be detachably attached. And the spring member 40 which has the protrusion part 41 which has a substantially C-shape in the fitting groove 23, and protrudes inside or outside a C-shape is provided.

図１に示すように、灯具２０は、例えば天井に取付けるベースプレート２４と、このベースプレート２４に旋回可能に取付けられた旋回板２５と、旋回板２５に回動可能に取付けられた一対のアーム部材２６を有しており、アーム部材２６の先端（ここでは下端）に灯具本体２７が回動可能に取付けられている。灯具本体２７は先端が開口した有底筒状の部材であり、内部にはランプ２１が取付けられる。
従って、灯具本体２７はあらゆる方向に向きを設定することができ、ランプ２１の光はあらゆる方向へ照射されることができる。 As shown in FIG. 1, the lamp 20 includes, for example, a base plate 24 attached to a ceiling, a turning plate 25 attached to the base plate 24 so as to be rotatable, and a pair of arm members 26 attached to the turning plate 25 so as to be rotatable. The lamp body 27 is rotatably attached to the tip end (here, the bottom end) of the arm member 26. The lamp body 27 is a bottomed cylindrical member having an open end, and the lamp 21 is mounted inside.
Therefore, the lamp body 27 can be set in any direction, and the light from the lamp 21 can be irradiated in any direction.

図２に示すように、灯具２０の取付部２２は円筒形状をしており、先端部の外周面には嵌合溝２３が設けられている。嵌合溝２３には、セード３０の嵌合突起３２が通過することができる開口部２３ａが設けられている。すなわち、セード３０の嵌合突起２３が２箇所に設けられている場合には、開口部２３ａも嵌合突起２３の位置に対応して２箇所以上設ける。なお、開口部２３ａには、バネ部材４０の端部を係止するためのストッパ２８が設けられている。また、図示はしないが、取付時に、セード３０の嵌合突起３２を嵌合溝２３に嵌合させてセード３０を回転させる際に、セード３０が所定の角度以上回転しないように、セード３０の回転方向終端にストッパが設けられている。   As shown in FIG. 2, the attachment portion 22 of the lamp 20 has a cylindrical shape, and a fitting groove 23 is provided on the outer peripheral surface of the tip portion. The fitting groove 23 is provided with an opening 23a through which the fitting protrusion 32 of the shade 30 can pass. That is, when the fitting protrusions 23 of the shade 30 are provided at two places, the opening 23 a is also provided at two or more places corresponding to the positions of the fitting protrusions 23. The opening 23 a is provided with a stopper 28 for locking the end of the spring member 40. Although not shown, when attaching the fitting protrusion 32 of the shade 30 to the fitting groove 23 and rotating the shade 30 during attachment, the shade 30 is prevented from rotating more than a predetermined angle. A stopper is provided at the end in the rotational direction.

図３に示すように、セード３０は下端側に照射面を有する全体円筒形状をしており、透明あるいは半透明の樹脂やガラスにより形成されている。セード３０の上端部には円筒形状の取付部３１が設けられており、取付部３１の内周面に嵌合突起３２が内側へ突出して設けられている。嵌合突起３２の形状は、例えば台形をしており、両端部には傾斜面を有するのが望ましい。なお、ここでは２箇所に嵌合突起３２を設けてあるが、１箇所でも可能である。また、３箇所以上設けることもできる。   As shown in FIG. 3, the shade 30 has an overall cylindrical shape having an irradiation surface on the lower end side, and is made of transparent or translucent resin or glass. A cylindrical attachment portion 31 is provided at the upper end portion of the shade 30, and a fitting protrusion 32 is provided on the inner peripheral surface of the attachment portion 31 so as to protrude inward. The shape of the fitting protrusion 32 is, for example, a trapezoid, and it is desirable that both ends have inclined surfaces. In addition, although the fitting protrusion 32 is provided in two places here, one place is also possible. Three or more locations can also be provided.

図４に示すように、バネ部材４０は一部に開口部４２を有する全体略Ｃ字形状をしており、外側へ突出した突出部４１を有している。バネ部材４０の全体的な半径は、嵌合溝２３の外周面、すなわち、灯具２０の取付部２２の外周面の内径よりも小さめにするのが望ましい。従って、バネ部材４０を嵌合溝２３の内部に取付ける際には、バネ部材４０の半径を大きくする方向へ拡げておき、嵌合溝２３の内部に収容してバネ部材４０を解放する。これにより、バネ部材４０は、弾性力により嵌合溝２３の内部において縮径するので、嵌合溝２３から脱落しないようになる。   As shown in FIG. 4, the spring member 40 has a substantially C-shape with an opening 42 in part, and has a protruding portion 41 protruding outward. The overall radius of the spring member 40 is preferably smaller than the inner diameter of the outer peripheral surface of the fitting groove 23, that is, the outer peripheral surface of the mounting portion 22 of the lamp 20. Therefore, when attaching the spring member 40 to the inside of the fitting groove 23, the spring member 40 is expanded in the direction of increasing the radius of the spring member 40 and accommodated in the fitting groove 23 to release the spring member 40. As a result, the spring member 40 is reduced in diameter inside the fitting groove 23 due to the elastic force, so that it does not fall out of the fitting groove 23.

突出部４１は、バネ部材４０における嵌合突起３２の取付時回転方向（図４中矢印Ａ方向）の終端４３ａの近傍に設けるのが望ましい。これにより、バネ部材の弾性を有効に活用することができ、良好な取付感が得られる。なお、突出部４１の形状は特に限定するものではないが、例えば三角形状や台形等傾斜面を有するのが望ましい。また、バネ部材４０の断面形状は任意であるが、ここでは、例えば円形断面を有している。   The protrusion 41 is preferably provided in the vicinity of the terminal end 43a in the rotation direction (direction of arrow A in FIG. 4) when the fitting protrusion 32 is attached to the spring member 40. Thereby, the elasticity of a spring member can be used effectively and a favorable attachment feeling is obtained. The shape of the protruding portion 41 is not particularly limited, but it is desirable to have an inclined surface such as a triangular shape or a trapezoid. Moreover, although the cross-sectional shape of the spring member 40 is arbitrary, it has a circular cross section here, for example.

また、図５に示すように、バネ部材４０の先端は折り曲げられて係止部４３が設けられており、この係止部４３は、嵌合溝２３の開口部２３ａに設けられているストッパ２８に引っ掛けられて係止される。これにより、嵌合突起３２がバネ部材４０の突出部４１を乗り越える際に、バネ部材４０が嵌合溝２３に対してずれるのを防止することができる。なお、係止部４３は、バネ部材４０の両端に設けるのが望ましい。   Further, as shown in FIG. 5, the distal end of the spring member 40 is bent to be provided with a locking portion 43, and the locking portion 43 is a stopper 28 provided in the opening 23 a of the fitting groove 23. It is hooked and locked. Thereby, it is possible to prevent the spring member 40 from being displaced from the fitting groove 23 when the fitting protrusion 32 gets over the protruding portion 41 of the spring member 40. Note that it is desirable to provide the locking portions 43 at both ends of the spring member 40.

次に、セード３０を灯具２０に取付ける動作について説明する。
セード３０の嵌合突起３２を灯具２０の嵌合溝２３の開口部２３ａの位置に合わせて、セード３０の取付部３１を灯具２０の取付部２２の外側に嵌め、セード３０を灯具２０に対して相対的に取付方向へ回転する。図６（Ａ）に示すように、セード３０の嵌合突起３２が、嵌合溝２３に取付けられているバネ部材４０の突出部４１に当接するので、さらにセード３０を回転させると、図６（Ｂ）に示すように、嵌合突起３２はバネ部材４０の突出部４１を乗り越えて、バネ部材４０の突出部４１と嵌合溝２３に設けられているストッパ（図示省略）との間に保持されることになる。このとき、バネ部材４０の端部に設けられている係止部４３は、嵌合溝２３に設けられているストッパ２８によって係止されているので、ずれない。 Next, an operation for attaching the shade 30 to the lamp 20 will be described.
The fitting protrusion 32 of the shade 30 is aligned with the position of the opening 23 a of the fitting groove 23 of the lamp 20, and the attachment portion 31 of the shade 30 is fitted to the outside of the attachment portion 22 of the lamp 20, so Rotate relatively in the mounting direction. As shown in FIG. 6 (A), the fitting protrusion 32 of the shade 30 abuts against the protrusion 41 of the spring member 40 attached to the fitting groove 23. Therefore, when the shade 30 is further rotated, FIG. As shown in (B), the fitting protrusion 32 gets over the protruding portion 41 of the spring member 40, and between the protruding portion 41 of the spring member 40 and a stopper (not shown) provided in the fitting groove 23. Will be retained. At this time, the locking portion 43 provided at the end portion of the spring member 40 is locked by the stopper 28 provided in the fitting groove 23 and thus does not shift.

以上説明したように、本発明の照明装置１０によれば、灯具２０の円形の取付部２１に設けられた嵌合溝２３に、セード３０の円形の取付部３１に設けられた嵌合突起３２を嵌合させ回転させることにより、セード３０を灯具２０に取付ける。このとき、嵌合突起３２がバネ部材４０の突出部４１を乗り越えるまでセード３０を相対的に回転させることにより、セード３０が灯具２０に対して緩む方向へ回転しようとしても一定以上の力で回転させなければバネ部材４０の突出部４１を乗り越えることができなくなるので、簡易かつ安価な部材により、セード３０が灯具２０から外れるのを確実に防止することができる。   As described above, according to the lighting device 10 of the present invention, the fitting protrusion 32 provided in the circular attachment portion 31 of the shade 30 is inserted into the fitting groove 23 provided in the circular attachment portion 21 of the lamp 20. The shade 30 is attached to the lamp 20 by fitting and rotating. At this time, by rotating the shade 30 relatively until the fitting protrusion 32 gets over the protruding portion 41 of the spring member 40, even if the shade 30 tries to rotate in a loosening direction with respect to the lamp 20, it rotates with a certain force or more. Otherwise, the protrusion 41 of the spring member 40 cannot be overcome, so that the shade 30 can be reliably prevented from being detached from the lamp 20 by a simple and inexpensive member.

なお、本発明の照明装置は、前述した実施形態に限定されるものでなく、適宜な変形，改良等が可能である。
例えば、前述した実施形態においては、灯具２０の取付部２２の外周面に嵌合溝２３を設け、セード３０の取付部３１の内周面に嵌合突起３２を設けた場合について説明したが、この他、灯具２０の取付部２２の内周面に嵌合溝を設け、セード３０の取付部３１の外周面に嵌合突起を設けることもできる。この場合には、バネ部材４０に設ける突出部を内側へ突出するように設けるのがよい。また、バネ部材４０の全体半径を灯具２０の取付部２２の内周面よりも大きめにしておくのが望ましい。
あるいは、灯具２０の取付部２２に嵌合突起を設け、セード３０の取付部３１に嵌合溝を設けることも可能である。 In addition, the illuminating device of this invention is not limited to embodiment mentioned above, A suitable deformation | transformation, improvement, etc. are possible.
For example, in the above-described embodiment, the case where the fitting groove 23 is provided on the outer peripheral surface of the attachment portion 22 of the lamp 20 and the fitting protrusion 32 is provided on the inner peripheral surface of the attachment portion 31 of the shade 30 has been described. In addition, a fitting groove can be provided on the inner peripheral surface of the attachment portion 22 of the lamp 20 and a fitting protrusion can be provided on the outer peripheral surface of the attachment portion 31 of the shade 30. In this case, the protrusion provided on the spring member 40 may be provided so as to protrude inward. In addition, it is desirable that the overall radius of the spring member 40 is made larger than the inner peripheral surface of the mounting portion 22 of the lamp 20.
Alternatively, it is possible to provide a fitting protrusion on the attachment portion 22 of the lamp 20 and provide a fitting groove in the attachment portion 31 of the shade 30.

また、前述した実施形態においては、灯具２０の取付部２２および灯具本体２７を円形断面としたが、取付部２２が円形であれば灯具本体２７の断面形状は円形に限定するものではない。また、セード３０についても同様に、取付部３１が円形であれば、セード３０の本体の形状は円形に限定するものではない。   In the embodiment described above, the attachment portion 22 and the lamp body 27 of the lamp 20 have a circular cross section, but the cross-sectional shape of the lamp body 27 is not limited to a circle as long as the attachment portion 22 is circular. Similarly, the shape of the body of the shade 30 is not limited to a circle as long as the attachment portion 31 is circular.

また、前述した実施形態においては、セード３０が灯具２０に対して回転しすぎないように嵌合溝２３にストッパを設けたが、バネ部材４０に突出部４１を複数箇所設けて、突出部４１間に嵌合突起３２を保持するようにすることもできる。   Further, in the above-described embodiment, the stopper is provided in the fitting groove 23 so that the shade 30 does not rotate with respect to the lamp 20, but the protrusion 41 is provided with a plurality of protrusions 41 on the spring member 40. The fitting protrusion 32 can be held between them.

以上のように、本発明にかかる照明装置は、灯具の円形の取付部とセードの円形の取付部の一方に設けられた嵌合溝に、他方に設けられた嵌合突起を嵌合させ回転させることにより、セードを灯具に取付ける。このとき、嵌合突起がバネ部材の突出部を乗り越えるまでセードを相対的に回転させる。これにより、セードが灯具に対して緩む方向へ回転しようとしても一定以上の力で回転させなければバネ部材の突出部を乗り越えることができないので、外れるのを確実に防止することができるという効果を有し、光源を有する灯具にセードを取付けた照明装置等として有用である。   As described above, the lighting device according to the present invention rotates by fitting the fitting protrusion provided on the other side into the fitting groove provided on one of the circular mounting portion of the lamp and the circular mounting portion of the shade. To attach the shade to the lamp. At this time, the shade is relatively rotated until the fitting protrusion gets over the protruding portion of the spring member.
