Abstract

PURPOSE:To make it possible to install, use and rotate verious lighting equipments interchangeably by connecting electrically wiring cords of a motor and a power source to the cap connector of a connection shaft, while linking electrically a wiring cord to a lighting equipment in an insulating bush and connecting to the connection shaft. CONSTITUTION:By inserting and fixing a connection shaft 53 covered with a cap connector 55 into the hollow of a rotary shaft 41 through an insulating bush 52, the hollow rotary shaft 41 is set to rotate around the connection shaft 53. While various kinds of lighting equipments 47 are installed rotatably integrally and dismountably to a rotary base 45, the wiring cord 54 to the lighting equipment 47 is connected electrically to the connection shaft 53 while linking electrically in the insulating bush 52. Wiring cords 33 and 57 to a motor 29 and a power source are connected electrically to the cap connector 55 of the connection shaft 53. As a result, even though the lighting equipment 47 is moved rotatively, such problems as an entangled condition and twisting-off of wire cords 33, 54, and 57 are never generated, and there is no requirement of maintenance and inspection.

By fitting and fixing the contact shaft to which the cap connector is attached through the insulating bushing, the hollow rotating shaft is set to rotate around the contact shaft, and is fixed on the output shaft of the motor. The pinion gear and the cyclone drive gear fixed on the hollow rotating shaft are meshed together, and various lighting equipment can be detachably attached to the rotating base so that they can rotate together, and the wiring cord to the lighting equipment can be connected to the rotating base. While electrically conductive in the insulating bushing and conductively connected to the contact shaft, the cap connector of the contact shaft is
This device is characterized in that the wiring cords to the motor and power source are electrically connected to each other.

) are hung integrally. The multiple screws (48)
In contrast, the stud (49) of the lighting fixture (47) is fitted from below and fastened and fixed with a cap nut (50). Therefore, by forming corresponding holes (51) for common screw receivers in the studs (49) of various lighting equipment (47),
Various types of lighting fixtures (47) can be attached to and used interchangeably on the rotating base (45), and all of the lighting fixtures (47) can be rotated by the motor (29). In addition, in the figure, a spotlight is illustrated as the lighting fixture (47).

Further, (52) is an insulating bushing that is fitted and integrated inside the hollow rotating shaft (41), and also has a bearing function. (53) is a contact shaft fitted to the conical upper end of the hollow rotating shaft (41) via its bush (52);

The central part of the shaft has a four-step surface so that the mounting screw (46) to the hollow rotating shaft (41) is sunk therein.

Previously, a ceiling-embedded rotary drive unit has been described. For example, as shown in the modification shown in FIG. By attaching the quick connection terminal block (25) to the inner surface of the top plate (21),
It is also possible to fix it directly to the ceiling board (10) by non-embedding. This is because even with such a configuration, the various lighting fixtures (47) can be rotated and used.

In that case, it goes without saying that the installation of the ceiling board (11) with the rubber board (12) can be omitted.
