グローブ３を保持する。The conventional glass glove holding structure for lighting equipment shown in FIG. 3 will be described. As shown in the figure, at the time of molding the glass globe 3, the projection 1 is provided at the opening thereof. The projection 1 is formed by gently curving the entire opening. On the other hand, the set screw 2 is attached to the instrument body 9. The set screw 2 is screwed in, and the hook is directly hooked near the projection 1 to hold the glass globe 3.

となることもある。The set screw 2 in FIG. 3 or FIG.
, The glass glove 3 is damaged. The holding force acts there. If the state continues for a long time, the glass globe 3 may be broken and fall. Further, when the glass glove 3 is applied to the instrument main body 9, the opening of the glass glove 3 may be erroneously applied to the instrument main body 9 and may be damaged. Further, the tip of the set screw 2 may not reach the protruding portion 1 and may not be able to be held due to variations at the time of molding the glass glove.
本発明の目的は、ガラスグローブの破損を防止し、か
つガラスグローブの保持強度を高めることである。An object of the present invention is to prevent breakage of a glass glove and increase the holding strength of the glass glove.
本発明におていは、板金で所定の枠状に形成され、か

先端を受ける平面部と該止めねじの先端部上面側を接す
る支持部とを含む。In the present invention, a protective metal fitting which is formed in a predetermined frame shape from sheet metal and is attached so as to cover the opening of the glass glove from the surroundings is used. The protection fitting includes a flat portion that receives the tip of the set screw and a support portion that contacts the upper surface of the tip of the set screw.

め、ガラスグローブの開口部を器具本体に誤って当てた
場合であっても、ガラスグローブが破損し難い。A protective fitting is interposed between the glass glove and the set screw. The set screw does not directly touch the glass glove, so the glass glove is not damaged. The holding metal has a role of covering and reinforcing the opening of the glass glob. For this reason, even when the opening of the glass glove is mistakenly applied to the instrument body, the glass glove is hardly damaged.

じ２で締付けて器具本体９に保持する保持構造である。An embodiment of FIGS. 1 and 2 according to the present invention will be described. 3 and 4 will be used here as they are, and a part of the overlapping description will be omitted as appropriate. The structure shown in FIGS. 1 and 2 is a holding structure for holding the glass globe 3 on the instrument body 9 by tightening it with the set screw 2.

係合し、支持部4aの外側は止めねじ２と係合する。止め
ねじ２は保護金具４を介してガラスグローブ３を締め付
け、保持する。In the present invention, there is provided a frame-shaped fitting 4 which is formed in a predetermined shape from a sheet metal and is attached to an opening of a glass globe 3 so as to cover the opening from the surroundings. A protection bracket 4 including a support portion 4a which contacts the upper surface of the tip of the set screw 2 is provided. The inside of the support 4a is engaged with the projection 1 formed at the opening of the glass globe 3, and the outside of the support 4a is engaged with the set screw 2. The set screw 2 tightens and holds the glass globe 3 via the protective fitting 4.
ガラスグローブ３と止めねじ２との間には保護金具４
が介在する。止めねじ２の先端は平面部4bに当たり、先
端部上面側は支持部4aに接する。止めねじ２はガラスグ
ローブ３に直に触れないので、ガラスグローブ３に傷が
つかない。Protective fitting 4 between glass globe 3 and set screw 2
Intervenes. The tip of the set screw 2 hits the flat portion 4b, and the top surface of the tip contacts the support portion 4a. Since the set screw 2 does not directly touch the glass globe 3, the glass glove 3 is not damaged.
保護金具４はガラスグローブ３の開口部を外側から覆

体９に装着する際に、ガラスグローブ３の開口部が器具
本体９に誤って当たることがあるが、保護金具４はその
際のガラスグローブ３の破損を防止する。The protective fitting 4 also has a role of covering the opening of the glass globe 3 from outside and reinforcing it. When the glass glove 3 is mounted on the apparatus main body 9, the opening of the glass glove 3 may erroneously hit the apparatus main body 9, but the protective fitting 4 prevents the glass glove 3 from being damaged at that time.
保護金具４は止めねじ２の当たる箇所だけに配置され

従って、止めねじ２の装着の折に、止めねじ２に保護金
具４を組付ける作業は不要である。The protective fitting 4 is not disposed only at the place where the set screw 2 is applied, but is a frame-like body which is widely disposed so as to cover the opening of the glass globe 3 from the periphery thereof. In addition, they are arranged in advance before the set screw 2 is mounted.
Therefore, there is no need to attach the protective fitting 4 to the set screw 2 when the set screw 2 is mounted.

い。The stress caused by the set screw 2 spreads widely to the opening of the glass globe 3 via the protective fitting 4. It does not concentrate on one location of the opening. For this reason, it becomes possible to hold the glass glove 3 firmly via the protective fitting 4. The glass globe 3 is made by expanding in a mold. In that connection,
Although the shape of the opening is not uniform and is considerably distorted, a plurality of appropriate portions of the opening are firmly engaged with the protective fitting 4 even if there is distortion, so that the distortion is less likely to be adversely affected.

ができる。The main feature of the present invention is to use a sheet-metal and frame-shaped protective metal fitting including a required flat part and a support part, and to mount it so as to cover the opening of the glass glove from the periphery. . According to this, breakage of the glass glove can be prevented, and the holding strength of the glass glove can be increased.
