Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to an improvement of the rotating mechanism part of a rotating light, and in particular, the structure of the rotating mechanism part of a small rotating light is simplified. .

[Conventional technology]

Conventionally, various types of rotating lights have been used that are attached to the top of the roof panels of emergency vehicles, etc., and are equipped with a mechanism that allows the direction of the light to be rotated. As a rotation mechanism for this purpose, a rim is rotatably connected to the motor shaft via a rotation transmission mechanism such as a gear, and a rotating part such as a reflecting mirror stand with a reflecting mirror erected and supported is attached to the rim. At the same time, the structure was such that power supply voltage was supplied to the light bulb located in front of the reflecting mirror.

[The problem that the idea aims to solve]

However, with the above conventional configuration, the number of parts in the rotating mechanism including the reflector increases, which not only increases the number of assembly steps, but also increases the structure of the rotating mechanism, making it difficult to downsize the entire rotating lamp. I had this problem.

The present invention was devised in view of the above-mentioned problems, and aims to simplify the structure of the rotating mechanism section of a rotating lamp and to downsize the entire rotating lamp.

[Means to solve the problem]

In order to achieve the above object, the rotating light according to the present invention is a rotating light equipped with a mechanism that rotates the direction of light projected by a reflector by slidingly rotating a motor shaft and a rim. A boss shaft comprising a socket into which a light bulb is inserted and locked is fitted on the shaft core, and is fastened and erected with the socket by a screw member having a through hole in the shaft core. The shaft center of a rim with an integrally molded reflector is rotatably attached to the shaft, and the motor shaft is in elastic contact with the outer periphery of the rim, so that the rotational force of the motor is directly transmitted to the rim. The gist of this is to

Further, in the rotating light according to the present invention, the rotating mechanism part, which consists of a rim formed integrally with the reflecting mirror, a boss shaft, a socket into which a light bulb is fixed, etc., is assembled by a single screw member that is screwed onto the board. It is configured as follows.

Incidentally, since a through hole is formed in the axis of the screw member, a conducting wire can be introduced into the socket through the through hole.

[Effect]

According to the above configuration, the rim integrally molded with the reflecting mirror is pivotally attached to the substrate via the boss shaft, and
Since the boss shaft is fastened together with the socket by a screw member penetrating the shaft core so as to protrude above the board, the rim, boss shaft,
The light bulb, the socket, and the reflecting mirror can be assembled by screwing one of the above-mentioned screw members onto the board. Furthermore, since the rim has a structure in which it is directly driven to rotate by the motor shaft, the operating noise of the rotating mechanism can be reduced, the number of parts in this part can be reduced, and the number of assembly steps can be omitted.

〔Example〕

Embodiments of the rotating light according to the present invention will be described below with reference to the drawings.

In the drawings, reference numeral 1 denotes a case having a board 3 fastened and fixed to its upper end surface by screws 2, and a screw hole 4 into which a screw member 5, which will be described later, is screwed is provided in the center of the board 3. On the upper surface side of the substrate 3, there is a boss shaft 8 into which the base of a socket 7 is inserted, which is configured to insert and lock a light bulb 6 in a replaceable manner into a stepped shaft hole bored in the shaft core. The screw member 5 inserted from the inner end of the base of the socket 7 is screwed into the screw hole 4 of the board 3 and fastened and fixed, and the shaft hole of the disc-shaped rim 9 is integrally formed with a reflecting mirror 10 having a concave mirror shape on the upper surface. The boss shaft 8 is inserted into the rim 11, and the rim 9 is rotatably attached thereto. Further, the screw member 5 includes:
A through hole 12 is bored in the axis, and the through hole 12
The conductive wire constituting the terminal 13 of the socket 7 is inserted from the bottom side of the board 3 through the terminal 1
3 is pressed into contact with the terminal of a light bulb 6 attached to a socket 7 by a coiled socket spring 14.

Reference numeral 18 denotes a support bracket made of an elastic material that is slidably pivoted to the bottom side of the substrate 3 via a screw shaft 19, and the motor 1 is attached to the support bracket 18.
6 is fixedly installed, and the motor 16 is elastically biased in a direction in which the motor 16 is tilted by the leaf spring bracket 20 of the support bracket 18, and the motor 16 is pressed against the annular sliding member 15 made of rubber fitted to the outer periphery of the rim 9. The motor shaft 1 of the motor 16 is pressed into contact with the motor shaft 1, and rotation is transmitted by sliding between the two. Since the drive connecting portion between the rim 9 and the motor shaft 17 is in elastic contact with the rubber annular sliding member 15 interposed, it not only provides quiet rotation but also prevents malfunctions. A structure with fewer causes can be realized.

Reference numeral 21 denotes a cover made of a translucent material, and is provided around the upper end of the case 1 so as not to hinder the rotation of the reflecting mirror 10.

In the rotating lamp having the above configuration, when the motor 16 is driven to rotate, the rim 9 rotates about the boss shaft via the sliding member 15 that comes into sliding contact with the motor shaft 17, and the reflecting mirror 10 integrated with the rim 9 rotates. Rotate around the light bulb 6. Therefore, the light source of the light bulb 6, which is always on when energized, is repeatedly illuminated by the reflecting mirror 10 and is visually recognized as a blinking light.

[Effect of idea]

Since the revolving light according to the present invention is constructed as described above, the rotating mechanism section consisting of the rim, boss shaft, and socket that is integrated with the reflecting mirror is assembled by a single screw member that is screwed onto the board. This structure simplifies the structure of the rotating mechanism and facilitates assembly, and there is no need to construct an extra drive connection structure such as a gear device between the reflector and the rim, making the overall rotating light compact. It has the characteristics of making it possible to reduce the operating noise and reduce the operating noise.
The practical effects after implementing the present invention are extremely large.
