本案は回転型照明器具に関するものである。此
種照明器具は電源コードのねじれを防止するため
に照明具、例えばフードの回転角を360度に規制
する様構成されている。[Detailed Description of the Invention] The present invention relates to a rotating lighting fixture. This type of lighting equipment is configured to restrict the rotation angle of the lighting equipment, such as the hood, to 360 degrees in order to prevent the power cord from twisting.
このために従来の照明器具では、フードを取付
ける支承枠を基台側に回転自在に枢着すると共
に、基台側に係止突起を設けて、この係止突起に
より支承枠を所定位置で係止して、該支承枠の
360度以上の回転を阻止する様に構成している。 For this purpose, in conventional lighting equipment, the support frame to which the hood is attached is rotatably pivoted to the base side, and a locking protrusion is provided on the base side, and the support frame is locked in a predetermined position by the locking protrusion. Stop and remove the bearing frame.
It is configured to prevent rotations of more than 360 degrees.
しかしながら、この様な構成では上記係止突起
の大きさだけ支承枠の回転角が減縮されるから、
実際には支承枠の回転角が360度以下になる事を
避けられず、従つて部分的に照射不能な箇処が生
じると云う欠点があつた。 However, in such a configuration, the rotation angle of the support frame is reduced by the size of the locking protrusion.
In reality, it is unavoidable that the rotation angle of the support frame is less than 360 degrees, which has the disadvantage that some parts cannot be irradiated.
本案はこの様な不利益を解消し得る回転型照明
器具を提供するものである。 The present invention provides a rotary lighting fixture that can eliminate such disadvantages.
以下に本案照明器具を添付図面につき説明する

片５と支承枠２とが係合状態の侭で上記係止片５
の係止部５２が基台３の突片３１と係合する迄回
転する。 Since the proposed lighting device is as described above, when the support frame 2 is rotated counterclockwise, the locking protrusion 23 of the support frame 2 moves within the engagement receiving portion 51 of the locking piece 5 to the left side thereof. The locking piece 5 engages with the locking edge 511, and then, while the locking piece 5 and the support frame 2 are in the engaged state, the locking piece 5
The locking portion 52 rotates until it engages with the protruding piece 31 of the base 3.

迄支承枠２が回転する。 Assuming that the bearing frame 2 is in the state shown in FIG. 3A when it has rotated counterclockwise and stopped, the bearing frame 2
When rotating clockwise, the locking protrusion 23 of the support frame 2 engages with the engagement receiving portion 5, contrary to the above-mentioned case.
1 and engages with the right side locking edge 512 as shown by the chain line in FIG.
The support frame 2 rotates until it comes into contact with the protrusion 31 of the base 3, as shown in FIG. 3B.
従つて支承枠２の回転角度は、係止片５に形成
された係合受部５１の長さｌだけ増大せしめら
