Description

【０００１】
【発明の属する技術分野】
本発明は、工事用コーンの頂部差し込み孔に差し込んで工事用コーンの頂部に立設する点滅灯や警告灯などの照明灯を、工事用コーンではなく例えばバリケードなどの横設単管（仮設パイプ）にも取り付けることができるようにした照明灯取付具に関するものである。
【０００２】
【従来の技術及び発明が解決しようとする課題】
工事用コーンが倒れた際に簡単に外れたり、また安易に抜き取られてしまうことのないように、図１５〜図１８に示すように照明灯２の差し込み部２Ａの外周部には下端部とそのやや上部寄りに周方向位置を９０度あるいは１８０度異ならせて抜け止め用係止突部１を形成し、また、一方工事用コーンＣの頂部には、内空部20と連通する差し込み孔21の内周の深さ方向に前記抜け止め用係止突部の通過を許容する通過凹溝22を形成している。
【０００３】
従って、照明灯２をコーンＣ頂部に立設する場合は、先ず通過凹溝22に下端部の抜け止め用係止突部１を位置させて、この係止突部１を通過凹溝22に嵌合させて通過させつつ照明灯２の差し込み部２Ａを差し込み孔21に差し込み、図１８に示すように下端部の係止突部１が差し込み孔21を抜けたところで、照明灯２を回動することで係止突部１が抜け止め状態となる。
【０００４】
そして、更に次の係止突部１が通過凹溝22に位置するところまで照明灯２を回動して更に差し込むことで図１９に示すように通過凹溝22にこの係止突部１が嵌合し、回り止め状態に固定されることとなり、照明灯２は単に引き抜こうとしても最初の係止突部１によって抜け止め状態となり、また次の係止突部１によって回り止め係止状態で固定され、コーンＣ頂部に立設できることとなる。
【０００５】
一方、このような照明灯は、コーンの頂部だけでなく、バリケードなどの単管に取り付けたい場合も多い。しかし、この場合、単に照明灯を差し込み支承する取付筒状部に単管抱持金具を設けただけでは、照明灯が安易に引き抜かれて持ち去られてしまう。
【０００６】
本発明は、単に照明灯を差し込み支承する取付筒状部に単管抱持用の取付金具を付設するのではなく、照明灯に設けられている既存の抜け止め用係止突部を利用して、単管にも容易に照明灯を取付できる上に、差し込み回動操作によってコーンの場合と同様に一旦差し込み取り付けすれば、安易に照明灯が引き抜かれて持ち去られない構造を、樹脂成形に際して形成する補強凹部によって容易に実現でき、しかも照明筒をガタ付き少なく支承保持できる画期的な照明灯取付具を提供することを目的としている。
【０００７】
【課題を解決するための手段】
添付図面を参照して本発明の要旨を説明する。
【０００８】
抜け止め用係止突部１を差し込み部２Ａの周面に設けた工事用コーン取付用の照明灯２の前記差し込み部２Ａを差し込み支承する取付筒状部３に、単管４に取付固定する単管取付部５を設けた照明灯取付具であって、前記取付筒状部３を樹脂で成形すると共に、この取付筒状部３の外面を凹設して内方へ突出する補強凹部６を形成し、この補強凹部６による内方突出部６Ａを前記取付筒状部３の周方向に配設すると共に、この内方突出部６Ａを有しないカ所を設けて前記抜け止め用係止突部１が抜き差し出入可能な係止突部通過可能部７を設け、この係止突部通過可能部７を通過させて前記照明灯２の差し込み部２Ａを前記取付筒状部３に差し入れた状態でこの照明灯２を回動して、前記係止突部通過可能部７と前記係止突部１との位置を周方向にずらすことで、この係止突部１が前記内方突出部６Ａにより抜け止め状態となるように構成したことを特徴とする照明灯取付具に係るものである。
【０００９】
また、前記取付筒状部３に形成した前記補強凹部６による内方突出部６Ａにより、この取付筒状部３に差し込んだ前記照明灯２の差し込み部２Ａを囲んで支承保持するように構成したことを特徴とする請求項１記載の照明灯取付具に係るものである。
【００１０】
また、前記取付筒状部３の周方向に複数の補強凹部６を形成して、この取付筒状部３に差し込む前記照明灯２の差し込み部２Ａの周囲に複数の前記内方突出部６Ａを形成し、この少なくとも隣り合う内方突出部６Ａ間に前記抜け止め用係止突部１が抜き差し出入可能な前記係止突部通過可能部７を設けたことを特徴とする請求項２記載の照明灯取付具に係るものである。
【００１１】
また、前記内方突出部６Ａ間の１ヵ所若しくは複数カ所のみを前記係止突部通過可能部７とし、各内方突出部６Ａ並びに他の内方突出部６Ａ間においては前記係止突部１の抜き差し出入を不可として、前記係止突部通過可能部７以外では前記係止突部１が抜け止め係止されるように構成したことを特徴とする請求項３記載の照明灯取付具に係るものである。
【００１２】
また、前記取付筒状部３の周方向に形成する前記補強凹部６を上下二段に設け、この上下の補強凹部６間に内方突出部６Ａを有しないカ所を設けて前記係止突部１が回動移動可能な係止突部回動可能部８を設けると共に、この下側の周方向に前記補強凹部６による内方突出部６Ａが有しないカ所を設けて、前記抜け止め用係止突部１が抜き差し出入可能な係止突部通過可能部７’を設けたことを特徴とする請求項１〜４のいずれか１項に記載の照明灯取付具に係るものである。
【００１３】
【発明の実施の形態】
好適と考える本発明の実施の形態（発明をどのように実施するか）を、図面に基づいてその作用効果を示して簡単に説明する。
【００１４】
係止突部１を係止突部通過可能部７に位置させて照明灯２の差し込み部２Ａを取付筒状部３に差し込み、係止突部１が係止突部通過可能部７を通過したところで回動すれば、係止突部１と係止突部通過可能部７との位置がズレ、補強凹部６による内方突出部６Ａによって係止突部１は抜け止め係止される。
【００１５】
また、この抜け止め状態となった照明灯２の差し込み部２Ａはその周囲を内方突出部６Ａによって支承保持されることとなる。
【００１６】
このように本発明によれば、向きを位置決めて差し込み回動することで、補強凹部６の内方突出部６Ａによって周囲が支承保持されつつ、単に引き抜こうとしても位置合わせしない限りこの内方突出部６Ａに既存の係止突部１が係止してそのまま引き抜けないため、抜け止め状態となり、安易に照明灯２を引き取れない。
【００１７】
従って、単管４に十分締め付けるなどして照明灯２を差し込み支承する取付筒状部３を単管４に固定すれば、この取付筒状部３に差し込んだ照明灯２が安易に引き抜かれてしまうことがない。
【００１８】
即ち、取付筒状部３を樹脂成形するに際して、補強凹部６による内方突出部６Ａの成形によって剛性を向上させるだけでなく、この内方突出部６Ａで囲むことで、ガタ付きなく照明灯２を支承保持できるように構成できると共に、この補強凹部６による内方突出部６Ａによって係止突部通過可能部７を設けることで、既存の差し込み部２Ａの係止突部１を利用して、単に差し込み回動することで取付筒状部３に照明灯２を差し込み支承すれば、再び回動しない限り引き抜けないように構成できる。
【００１９】
また言い換えれば、このような内方突出部６Ａによる照明灯２の支承保持構造や、内方突出部６Ａを有しないカ所、例えば内方突出部６Ａ間の係止突部通過可能部７の形成も、取付筒状部３を樹脂製としこの樹脂成形によって容易に製作でき、またこの補強凹部６はこの樹脂製の取付筒状部３の補強作用も果たし、また照明灯２（差し込み部２Ａ）の寸法の違いに対応して多少内方突出部６Ａが変形あるいは柔軟可動するように構成できるため、周囲の内方突出部６Ａ内に照明灯２の差し込み部２Ａを圧入差し込みすることでガタ付きなく照明灯２を支承保持できることとも容易に可能となる。
【００２０】
【実施例】
本発明の具体的な実施例について図面に基づいて説明する。
【００２１】
取付筒状部３を樹脂で成形する共に、この樹脂成形時に取付筒状部３の外面を凹設して内方へ突出する補強凹部６を一体形成し、この補強凹部６による内方突出部６Ａを前記取付筒状部３の周方向に配設するように構成している。
【００２２】
また、本実施例では、この内方突出部６Ａを有しないカ所を設けて前記抜け止め用係止突部１が抜き差し出入可能な係止突部通過可能部７を設け、この係止突部通過可能部７を通過させて前記照明灯２の差し込み部２Ａを前記取付筒状部３に差し入れた状態でこの照明灯２を回動して、前記係止突部通過可能部７と前記係止突部１との位置を周方向にずらすことで、この係止突部１が前記内方突出部６Ａにより、抜け止め状態となるように構成している。
【００２３】
具体的には、樹脂成形によって形成した前記補強凹部６による内方突出部６Ａにより、この取付筒状部３に差し込んだ前記照明灯２の差し込み部２Ａを囲んでガタ付くことをできるだけ防止して支承保持するように構成するが、この取付筒状部３の周方向に複数の補強凹部６を形成して、この取付筒状部３に差し込む前記照明灯２の差し込み部２Ａの周囲に複数の前記内方突出部６Ａを形成し、この内方突出部６Ａ間の１ヵ所のみを前記係止突部１が通過できる幅に設定して前記係止突部通過可能部７とし、他の内方突出部６Ａ間の間隔は係止突部１が通過できない幅として係止突部１の抜き差し出入を不可として、前記係止突部通過可能部７以外では前記係止突部１が抜け止め係止されるように構成している。
【００２４】
また、図９〜図１６に示す第二実施例では、前記取付筒状部３の周方向に形成する前記補強凹部６を上下二段に設け、上側の周方向には、間隔を置いて補強凹部６を形成し、この補強凹部６による内方突出部６Ａの間隔は、前述のように前記係止突部１が通過できる幅に設定して、この内方突出部６Ａのうちの一ヵ所を前記係止突部通過可能部７とし、他の補強凹部６間の下端部はやや内方へ突出させて係止突部１の抜き差し出入を不可として、前記係止突部通過可能部７以外では前記係止突部１が抜け止め係止されるように構成している。また、下側の周方向にも前記補強凹部６による内方突出部６Ａが有しないカ所を設けて、前記抜け止め用係止突部１が抜き差し出入可能な係止突部通過可能部７’を設けた構成としている。
【００２５】
また、この上下の補強凹部６間に内方突出部６Ａを有しないカ所を設けて前記係止突部１が回動移動可能な係止突部回動可能部８を設けている。
【００２６】
従って、図８，図１５に示すように係止突部１を係止突部通過可能部７に位置させて照明灯２の差し込み部２Ａを取付筒状部３に差し込み、係止突部１が係止突部通過可能部７を通過したところで回動すれば、係止突部１と係止突部通過可能部７との位置がズレ、補強凹部６による内方突出部６Ａによって係止突部１は抜け止め係止される。しかも、この第二実施例では図１５に示すように、更に次の係止突部１が係止突部通過可能部７に位置するところまで回動して更に照明灯２を差し込むことで、次の係止突部１は上側の一の内方突出部６Ａ間の係止突部通過可能部７に嵌合し、下側の係止突部１は下側の内方突出部６Ａ間の係止突部通過可能部７’に嵌合して回り止め状態に固定されるように構成している。
【００２７】
従って、この抜け止め状態となった照明灯２の差し込み部２Ａは、係止突部１が係止突部通過可能部７に嵌合することで回り止め状態となると共に、その周囲を内方突出部６Ａによって支承保持されることとなる。
【００２８】
このように、向きを位置決めて差し込み回動することで、補強凹部６の内方突出部６Ａによって周囲が支承保持されつつ、単に引き抜こうとしても位置合わせしない限りこの内方突出部６Ａに既存の係止突部１が係止してそのまま引き抜けないため、抜け止め状態となり、安易に照明灯を引き取れない。
【００２９】
従って、単管４に取付筒状部３に設けた単管取付部５の締付ネジを十分締め付けるなどして照明灯２を差し込み支承する取付筒状部３を単管４に固定すれば、この取付筒状部３に差し込んだ照明灯２が安易に引き抜かれてしまうことがない。
【００３０】
即ち、取付筒状部３を樹脂成形するに際して、補強凹部６の成形によって周囲を内方突出部６Ａで囲み、たとえゴム材などの柔軟性材で形成しなくても、ガタ付きなく照明灯２を支承保持でき、この補強凹部６による内方突出部６Ａによって係止突部通過可能部７を設けて、既存の差し込み部２Ａの係止突部１を利用して差し込み回動することで、再び回動しない限り引き抜けないように構成して、安易に引き抜きできないように構成することが樹脂成形によって安易に実現できることとなる。
【００３１】
また言い換えれば、このような内方突出部６Ａによる照明灯２の支承保持構造や、内方突出部６Ａを有しないカ所、例えば内方突出部６Ａ間の係止突部通過可能部７の形成も取付筒状部３を樹脂製とすることで容易に製作でき、またこの補強凹部６はこの樹脂製の取付筒状部３の補強作用も果たし、また照明灯２（差し込み部２Ａ）の寸法の違いに対応して多少内方突出部６Ａが変形あるいは柔軟可動するように構成できるため、周囲の内方突出部６Ａ内に照明灯２の差し込み部２Ａを圧入差し込みすることでガタ付きなく照明灯２を支承保持できることとなる。
【００３２】
しかも、上下二段に補強凹部６（内方突出部６Ａ）を形成する実施例では、補強凹部６が上下に配され、上下に夫々周方向に配した補強凹部６の内方突出部６Ａによって照明灯２が支承されるため、取付筒状部３の強度が一層向上すると共に、一層照明灯２の支承強度も向上し、また安易には引き取れない構造を樹脂成形によって容易に実現できることとなる。
【００３３】
尚、本発明は、本実施例に限られるものではなく、各構成要件の具体的構成は適宜設計し得るものである。
【００３４】
【発明の効果】
本発明は上述のように構成したから、単に照明灯を差し込み支承する取付筒状部に単管抱持用の取付金具を付設するのではなく、照明灯に設けられている既存の抜け止め用係止突部を利用して、単管にも容易に照明灯を取付できるだけでなく、差し込み回動操作によってコーンの場合と同様に一旦差し込み取り付けすれば、安易に照明灯を引き抜き持ち去られない構造を、樹脂成形に際する補強凹部によって実現でき、しかも照明筒をガタ付き少なく支承保持できる照明灯となる。
【００３５】
即ち、取付筒状部を樹脂成形するに際して、補強凹部の成形によってガタ付きなく照明灯を支承保持できるように構成できると共に、この補強凹部による内方突出部によって係止突部通過可能部を設けることで、既存の差し込み部の係止突部を利用して、単に差し込み回動することで取付筒状部に照明灯を差し込み支承すれば、再び回動しない限り引き抜けないように構成でき、内方突出部による照明灯の支承保持構造や、内方突出部を有しないカ所、例えば内方突出部間の係止突部通過可能部の形成も、取付筒状部を樹脂製としこの樹脂成形によって、容易に製作できる画期的な照明灯取付具となる。
【００３６】
また、請求項２，３記載の発明においては、一層ガタ付きなく強固に支承保持できると共に、容易に引き抜けない構造を容易に製作できる一層実用性に秀れた照明灯取付具となる。

As shown in FIGS. 15 to 18, the outer peripheral portion of the insertion portion 2 A of the illuminating lamp 2 is provided with a lower end portion so that the construction cone does not easily come off when it falls down and is not easily pulled out. A retaining projection 1 for preventing slippage is formed at a slightly different position in the circumferential direction by 90 degrees or 180 degrees, and an insertion hole communicating with the inner space 20 is formed at the top of the construction cone C. A through-groove 22 is formed in the depth direction of the inner periphery of 21 to allow passage of the retaining locking projection.
[0003]
Accordingly, when the illuminating lamp 2 is erected on the top of the cone C, first, the locking projection 1 for retaining the lower end is positioned in the passage groove 22, and this locking projection 1 is formed in the passage groove 22. The insertion portion 2A of the illuminating lamp 2 is inserted into the insertion hole 21 while being fitted and passed, and the illumination lamp 2 is rotated when the locking projection 1 at the lower end passes through the insertion hole 21 as shown in FIG. By doing so, the locking projection 1 is prevented from coming off.

Then, the illumination lamp 2 is further rotated and inserted until the next locking projection 1 is located in the passage groove 22, so that the locking projection 1 is inserted into the passage groove 22 as shown in FIG. The lighting lamp 2 is fixed in a non-rotating state, and the illuminating lamp 2 is prevented from being pulled out by the first locking projection 1 even if it is simply pulled out, and is also locked in the non-rotating state by the next locking projection 1 And can be erected on the top of the cone C.
[0005]
On the other hand, there are many cases where such an illuminating lamp is desired to be attached not only to the top of the cone but also to a single tube such as a barricade. However, in this case, the illuminating lamp is easily pulled out and taken away simply by providing a single-tube holding bracket on the mounting cylindrical portion for inserting and supporting the illuminating lamp.
[0006]
The present invention does not simply attach a mounting bracket for holding a single tube to a mounting cylindrical portion that inserts and supports an illuminating lamp, but uses an existing locking projection provided on the illuminating lamp. In addition, it is possible to easily attach an illuminating lamp to a single tube, and once it is inserted and attached in the same manner as in the case of a cone by inserting and turning, a structure in which the illuminating lamp can be easily pulled out and not taken away can be used for resin molding. It is an object of the present invention to provide an epoch-making illuminating light fixture that can be easily realized by a reinforcing concave portion to be formed and that can support and hold an illumination tube with little play.

DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention (how to carry out the invention) considered to be suitable will be briefly described with reference to the drawings, showing its effects.
[0014]
The locking projection 1 is positioned at the locking projection passing portion 7, the insertion portion 2 A of the illuminating lamp 2 is inserted into the mounting tubular portion 3, and the locking projection 1 passes through the locking projection passing portion 7. If the rotation is performed at this point, the positions of the locking protrusion 1 and the locking protrusion passing portion 7 are displaced, and the locking protrusion 1 is locked to come off by the inward protruding portion 6A formed by the reinforcing recess 6.
[0015]
In addition, the insertion portion 2A of the illuminating lamp 2 that has been prevented from being detached is supported and held by the inward protruding portion 6A around the insertion portion 2A.

Can be configured to be able to support and hold, and by providing the locking protrusion passing portion 7 by the inward protruding portion 6A by the reinforcing recess 6, the locking protrusion 1 of the existing insertion portion 2A is used, If the illuminating lamp 2 is inserted and supported by simply inserting and turning it, it can be configured not to be pulled out unless it is turned again.
[0019]
In other words, the structure for supporting and holding the illuminating lamp 2 by the inward projecting portion 6A, and the formation of the portion 7 that does not have the inward projecting portion 6A, for example, the locking projecting portion passing portion 7 between the inward projecting portions 6A. However, the mounting cylindrical portion 3 is made of resin and can be easily manufactured by this resin molding. The reinforcing concave portion 6 also serves to reinforce the resin mounting cylindrical portion 3, and the illumination lamp 2 (insertion portion 2A). Since the inner projecting portion 6A can be deformed or flexibly moved to correspond to the difference in dimensions, the insertion portion 2A of the illumination lamp 2 is press-inserted into the surrounding inner projecting portion 6A. It is also possible to easily support and hold the illumination lamp 2.
[0020]
【Example】
Specific embodiments of the present invention will be described with reference to the drawings.
[0021]
The mounting cylindrical portion 3 is molded with resin, and the outer surface of the mounting cylindrical portion 3 is recessed at the time of resin molding to integrally form a reinforcing recess 6 that protrudes inward. 6A is configured to be disposed in the circumferential direction of the mounting cylindrical portion 3.
[0022]
Further, in this embodiment, a portion not having the inward projecting portion 6A is provided, and a locking projection passage allowing portion 7 in which the retaining locking locking projection 1 can be inserted and removed is provided. The illuminating lamp 2 is rotated in a state in which the insertion portion 2A of the illuminating lamp 2 is inserted into the mounting cylindrical portion 3 through the passable portion 7, so that the engaging projection passing portion 7 and the engaging portion are engaged. By shifting the position of the locking projection 1 in the circumferential direction, the locking projection 1 is configured to be prevented from being detached by the inward protruding portion 6A.
[0023]
Specifically, the inner projecting portion 6A by the reinforcing recess 6 formed by resin molding prevents the ratchet as much as possible from surrounding the insertion portion 2A of the illuminating lamp 2 inserted into the mounting cylindrical portion 3. Although it is configured to support and hold, a plurality of reinforcing recesses 6 are formed in the circumferential direction of the mounting cylindrical portion 3, and a plurality of surroundings are provided around the insertion portion 2 A of the illuminating lamp 2 inserted into the mounting cylindrical portion 3. The inward projecting portion 6A is formed, and only one portion between the inward projecting portions 6A is set to a width that allows the engaging projection 1 to pass through to form the engaging projection passing portion 7. The spacing between the protruding portions 6A is such that the locking projection 1 cannot pass through, so that the locking projection 1 cannot be inserted / removed. It is configured to be locked.
[0024]
Further, in the second embodiment shown in FIGS. 9 to 16, the reinforcing concave portions 6 formed in the circumferential direction of the mounting cylindrical portion 3 are provided in two upper and lower stages, and the upper circumferential direction is reinforced at intervals. A recess 6 is formed, and the interval between the inward protrusions 6A by the reinforcing recess 6 is set to a width that allows the locking protrusion 1 to pass through as described above, and one of the inward protrusions 6A. The lower end portion between the other reinforcing recesses 6 projects slightly inward so that the locking projection 1 cannot be inserted / removed, and the locking projection passing portion 7 is allowed to pass. In other cases, the locking projection 1 is configured to be retained and locked. In addition, a portion that does not have the inward projecting portion 6A formed by the reinforcing recess 6 is provided also in the lower circumferential direction, and the locking projection passing portion 7 ′ through which the retaining locking projection 1 can be inserted and removed. It is set as the structure which provided.
[0025]
In addition, a portion that does not have the inward projecting portion 6A is provided between the upper and lower reinforcing recesses 6 to provide a locking projection rotating portion 8 in which the locking projection 1 can be rotated.
[0026]
Accordingly, as shown in FIGS. 8 and 15, the locking projection 1 is positioned at the locking projection passing portion 7, and the insertion portion 2 A of the illuminating lamp 2 is inserted into the mounting tubular portion 3. If it rotates at the position where it passes through the locking projection passable portion 7, the positions of the locking projection 1 and the locking projection passing portion 7 are shifted, and locked by the inward protruding portion 6 A by the reinforcing recess 6. The protrusion 1 is latched and locked. In addition, in this second embodiment, as shown in FIG. 15, by further rotating the next locking projection 1 to a position where it is located in the locking projection passing portion 7, and further inserting the illumination lamp 2, The next locking projection 1 fits into the locking projection passing portion 7 between the upper one inner projection 6A, and the lower locking projection 1 is between the lower inner projection 6A. It is configured so as to be fitted to the locking protrusion passing part 7 ′ and fixed in a non-rotating state.
[0027]
Therefore, the insertion portion 2A of the illuminating lamp 2 that has been prevented from coming off is prevented from rotating when the locking projection 1 is fitted to the locking projection passing portion 7, and the periphery of the insertion portion 2A is inward. It will be supported and held by the protruding portion 6A.
[0028]
In this way, by positioning and turning, the periphery is supported and held by the inward projecting portion 6A of the reinforcing recess 6, but the inner projecting portion 6A has an existing one as long as it is not aligned even if it is simply pulled out. Since the locking projection 1 is locked and cannot be pulled out as it is, the locking projection 1 is prevented from being pulled out, and the illumination lamp cannot be pulled out easily.
[0029]
Accordingly, if the mounting tubular portion 3 for inserting and supporting the illuminating lamp 2 is fixed to the single tube 4 by sufficiently tightening the fastening screw of the single tube mounting portion 5 provided in the mounting tubular portion 3 to the single tube 4, The illuminating lamp 2 inserted into the mounting tubular portion 3 is not easily pulled out.
[0030]
That is, when the mounting tubular portion 3 is molded with resin, the reinforced recess 6 is formed so that the periphery is surrounded by the inward protruding portion 6A, and even if it is not formed of a flexible material such as a rubber material, the illuminating lamp 2 is free from backlash. By providing a locking projection passing portion 7 by the inward protruding portion 6A by the reinforcing recess 6 and inserting and turning using the locking projection 1 of the existing insertion portion 2A, It can be easily realized by resin molding so as not to be pulled out unless it is rotated again and configured so as not to be pulled out easily.
[0031]
In other words, the structure for supporting and holding the illuminating lamp 2 by the inward projecting portion 6A, and the formation of the portion 7 that does not have the inward projecting portion 6A, for example, the locking projecting portion passing portion 7 between the inward projecting portions 6A. Can be easily manufactured by making the mounting cylindrical portion 3 made of resin, and the reinforcing concave portion 6 also serves to reinforce the mounting cylindrical portion 3 made of resin, and the dimensions of the illumination lamp 2 (insertion portion 2A). The inner projecting portion 6A can be configured to be deformed or flexibly moved to correspond to the difference between the two, so that the illumination portion 2A can be illuminated without being rattled by press-fitting the insertion portion 2A of the lamp 2 into the surrounding inner projecting portion 6A. The lamp 2 can be supported and held.
[0032]
In addition, in the embodiment in which the reinforcing recesses 6 (inward projecting portions 6A) are formed in two upper and lower stages, the reinforcing recesses 6 are arranged vertically, and the inward projecting portions 6A of the reinforcing recesses 6 are arranged vertically in the circumferential direction. Since the illuminating lamp 2 is supported, the strength of the mounting cylindrical portion 3 is further improved, the supporting strength of the illuminating lamp 2 is further improved, and a structure that cannot be easily pulled out can be easily realized by resin molding. .
[0033]
Note that the present invention is not limited to this embodiment, and the specific configuration of each component can be designed as appropriate.
[0034]
【The invention's effect】
Since the present invention is configured as described above, it is not simply provided with a mounting bracket for holding a single tube on a mounting cylindrical portion for inserting and supporting an illuminating lamp. Not only can the lamp be easily attached to a single tube using the locking projection, but it can be easily pulled out and taken away once it is inserted and attached in the same way as a cone by turning and inserting. Thus, an illuminating lamp can be realized by a reinforcing concave portion in resin molding, and the lighting tube can be supported and held with little play.
[0035]
That is, when the mounting cylindrical portion is molded with resin, it can be configured to support and hold the illuminating lamp without rattling by forming the reinforcing recessed portion, and the locking protruding portion passing portion is provided by the inward protruding portion by the reinforcing recessed portion. So, using the locking protrusion of the existing insertion part, if you insert and support the illumination lamp by simply inserting and turning it, you can configure it so that it will not pull out unless it rotates again, The structure for supporting and supporting the lamp by the inward projecting part, and the formation of the part that does not have the inward projecting part, for example, the locking projecting part passing part between the inward projecting parts, is made of this mounting resin made of resin By molding, it becomes an epoch-making lighting fixture that can be easily manufactured.
[0036]
Further, in the inventions according to claims 2 and 3, the illuminating lamp fixture can be more firmly supported and held with less backlash, and can be easily manufactured with a structure that cannot be easily pulled out.
[0037]
Further, in the invention according to claim 4, it can be taken out as it is only at the pivoting position where it is pulled out at the time of pivoting, and it becomes easy for a user who knows this structure to attach and detach. It becomes a lighting fixture.
[0038]
Further, in the invention according to claim 5, since the reinforcing recesses are arranged vertically, and the illuminating lamp is supported by the inwardly projecting portions of the reinforcing recesses arranged in the circumferential direction, respectively, the strength of the mounting cylindrical portion is increased. Further improved, the bearing strength of the illuminating lamp is further improved, and a structure that cannot be easily pulled out can be easily realized by resin molding.
