Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a socket mounting device for mounting a lamp socket of a lighting device.

Fig. 1 is a vertical sectional view showing the state of a conventional inverted Fuji type multi-lamp lighting fixture before the reflector plate is attached. In the figure, 1 is the lighting fixture body, 2 is the lamp socket 3.
4 is a reflecting plate, 4a is a socket insertion portion provided on this reflecting plate, _W1 is the socket width, and _W2 is the notch width.

In the lighting equipment configured as above,
After a lamp socket 3 is attached to a lighting fixture body 1 via a socket mount 2, a reflector plate 4 is attached. However, in some lighting equipments, the mounting direction of the reflector 4 is not parallel to the orientation of the lamp socket 3,
For example, in the above-mentioned inverted Fuji-shaped multi-lamp fixtures where the reflective surfaces for each lamp and lamp socket are not parallel to each other, the notch width W ₂ of the socket insertion part 4a at both ends of the reflector plate 4 should be set in the mounting direction of the reflector plate 4. The width is set to match the projected shape of the lamp socket 3 from above, and is made larger than the width _W1 of the lamp socket 3. Therefore, a large gap W ₁ -W ₂ is created around the lamp socket 3, which is a major drawback in terms of the external design.

In order to improve this problem, some socket mounting devices have been devised so that the lamp socket 3 is not fixed to the appliance body 1, but rotates in a plane perpendicular to the lamp axis. The disadvantage was that the number of parts increased, making it difficult to assemble. In particular, in the case of multi-lamp lighting fixtures, where the rotating axis of the socket base is parallel to the lamp axis, there are two types: one with the left side of the socket base as the rotation axis, and the other with the right side as the rotation axis. It is necessary to install two types of socket bases, one with a moving shaft and the other, which makes it complicated and large.
In addition, the side of the socket base perpendicular to the lamp axis has a sharp edge, which requires special consideration to protect the wire coating.

FIG. 2 is a front view of a part of a conventional inverted Fuji-shaped multi-lamp lighting fixture. In the figure, 1 to 4 indicate the same or equivalent parts as in FIG. 1, and 5 indicates a lamp attached to the lamp socket 3. It is. Generally, in this type of lighting equipment, it is difficult to insert the lamp 5 into the lamp socket 3 due to the fit margin when inserting the lamp socket 3 into the socket base 2, the structure of the socket base 2, especially the fit margin for the rotation shaft, etc. When the lamp socket 3 is tilted backward at an angle α,
This has disadvantages in that it may cause poor contact of the lamp 5, or in some cases may cause the lamp 5 to fall, and is also undesirable in terms of design.

The present invention was made in order to improve the above-mentioned drawbacks of the conventional devices. The object of the present invention is to provide a socket mounting device for a lighting fixture that is excellent in design, compact, easy to work with, and safe by tilting the socket base forward at times.

Next, one embodiment of the present invention will be described in detail with reference to the drawings. FIG. 3 is an exploded perspective view showing a socket mounting device according to an embodiment of the present invention viewed from below, and FIG. 4 is a partial front view showing a state in which a lamp is attached. 5 to 5 indicate the same or corresponding parts as in FIGS. 1 and 2. Reference numeral 6 denotes a socket base mounting plate to be attached to the lighting device body 1, and a base 7 to be attached to the lighting device body 1, and a socket base mounting plate 6 to be installed in the same direction from the tip so as to form a substantially U-shape with this base 7 as the base. A support leg 8 is bent and connected to each other, and a socket base support is connected to each other by bending it outward from both sides so as to form a U-shape that opens outward from each other with the tip of the support leg 8 as a base. pieces 9, and socket base locking portions 10, 10a formed of cylindrical protrusions that project outward from each other from approximately the center of these socket base support pieces 9.
Consisting of

The socket base 2 includes a base plate 12 having a socket mounting portion 11 for attaching the lamp socket 3, and a base plate 1
Two wing pieces 13 are connected to each other by bending in a substantially U-shape in the same direction from both ends of the socket base 2, and are rotatably attached to the socket base support piece 9 in a circumscribed manner. A circular engagement hole 14 that rotatably engages with the socket base locking portion 10 of the socket base mounting plate 6, and an engagement hole 14 of the wing piece 13.
A guide curved portion 15 is formed by bending a portion of the distal end side outward from the engagement hole 14 with a gap therebetween. 16 is a lead wire connected to the lamp socket 3.

In the above configuration, the relative positions of the opposing socket base locking portions 10 and 10a are such that, as shown in FIG. It is positioned so as to give a height difference of h in the direction. On the other hand, the distances of the engagement holes 14 from the base 12 are the same.

In the lighting fixture socket mounting device configured as described above, when the guide curved portion 15 of the socket base 2 is applied to the socket base locking portion 10 of the socket base mounting plate 6 and the socket base 2 is pushed in, the socket base 2 is pushed in. By utilizing the elastic deformation of the socket base support piece 9 and the wing piece 13, the socket base locking portion 10 can be inserted into the engagement hole 14, and the socket base 2 can be freely rotated on the socket base mounting plate 6. Moreover, it can be installed securely with just one touch. Here, the guide curved portion 15 facilitates the installation work.

The installed state is shown in FIG. 4, and the relative position of the pair of opposing socket base locking parts 10, 10a provided on the socket base support piece 9 of the socket base mounting plate 6 is not horizontal but in the horizontal direction. The engagement holes 14, 14 provided in the socket base 2 have a height difference h from the socket base 2.
The lamp socket 3 inserted into the socket mounting portion 11 of the socket base 2 is tilted forward at an angle θ between the lamp socket 3 and the lamp shaft. When the lamp 5 is attached to the lamp socket 3 in this state, the lamp socket 3 is tilted backward by an angle θ and corrected to the normal position 3a.

In the present invention, since the socket base 2 rotates, the socket insertion portion 4a of the reflector plate 4 only needs to be inscribed with the minimum external dimension of the socket.Therefore, a large gap that is undesirable in appearance does not occur, and the structure can be improved. There are only two types of parts: the socket base 2 and the socket base mounting plate 6, and the rotating shaft (in actual examples, screws, rods, dowel pins, etc.) and the many screws, nuts, washers, etc. that support it. No parts are required, and one type of socket base 2 can be used even if the fixture is for multiple lights. Since the socket base 2 can be attached to either the right or left support leg 8 of the socket base mounting plate 6, assembly work is also simple. Further, the lead wire 16 of the lamp socket 3 comes into contact with the bent portion of the blade 13 of the socket base 2, so there is no need to consider protection of the wire sheathing, and this is much more economical than the conventional example.

In addition, the socket can be tilted forward by making a slight deviation in the socket base locking parts 10 and 10a, which prevents poor contact of the lamp 5 and falling of the lamp 5, which is extremely safe. , the amount by which the socket retreats due to the margin of the engaging portion of the lamp socket 3 and the socket base 2, and
The angle θ, that is, the step t{θ=
By adjusting tan ^-1 (h/distance between socket support pieces 9, 9), the lamp 5 assumes a vertical position when attached to the lamp socket 3, which is also desirable in terms of appearance. Furthermore, by tilting the socket base 2 forward, the force received when attaching the lamp 5 causes the socket base 2 to tilt backward, thereby preventing the socket base 2 from coming off from the socket base locking parts 10, 10a and falling off. The engagement hole 14 can be securely engaged with the socket base engagement part 10 to prevent this.

In the above embodiment, in order to tilt the socket base 2 forward, the opposing socket base locking portions 1
Although a step is given to the relative positions of the sockets 0 and 10a, the socket base locking portions 10 and 10a may be placed at the same position and a step is given to the engagement holes 14 and 14. Further, in the above embodiment, the socket base 2 is provided with an engaging hole 14, and the socket base mounting plate 6 is provided with a socket base locking portion 1 consisting of a protrusion.
0 is provided, but conversely, a protrusion may be provided on the socket base 2 to serve as an engaging portion, and a hole to engage with this may be provided on the socket base mounting plate 6 to serve as a socket locking portion.In this case, the above-mentioned By providing a step in the relative position of either the engaging portion or the hole, the same effects as in the above embodiment can be achieved. Furthermore, in either case, it is free to decide whether the wing pieces 13 of the socket base 2 are inscribed or circumscribed in the socket base support piece 9, and accordingly, the protruding direction of the socket base locking portion 10 can also be changed. .

The present invention is applicable not only to inverted Fuji-shaped multi-light lighting fixtures but also to other lighting fixtures.

As described above, according to the present invention, a socket base mounting plate that is attached to the device body and a socket base that is rotatably attached to the socket base mounting plate are provided, and the socket base is tilted forward.
It has an excellent design, is compact, and is easy to work with.
