Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a lighting fixture of a single-base type lamp, a small shade, and a bottom opening type.

[Prior Art] FIG. 6 shows the appearance of a conventional lighting fixture. An arm 2 is rotatably provided on an upper part of a fixture body 1, and a shade receiver 3 is provided on an upper part of the arm 2. . Ced receiver 3
As shown in FIG. 7, a socket 6 for supporting a lamp (one-sided fluorescent lamp) 4 is provided therein, and the shade 5 is detachably attached to the shade receiver 3. The shade 5 has an opening on the lower surface.

As shown in FIG. 8, protrusions 8 are provided on the upper and lower surfaces of the base portion 7 of the lamp 4, and correspondingly, elastic spring pieces 9 are formed above and below the socket 6. Has been done. Further, slits 10 are formed on both sides of the socket 6, and projections 11 that fit into the slits 10 are provided on the base portion 7 so as to project.

The lamp 4 is held by the upper and lower spring pieces 9 of the socket 6 arranged inside the shade receiving tool 3, as shown in FIG.
As shown in FIG. 5, when replacing the lamp 4, the shade 5 is removed, and as shown in FIG.
The lamp 4 can be replaced by pulling it in the forward direction so that the base portion 7 of the lamp 4 bends the spring piece 9 of the socket 6 and gets over it. When the lamp 4 is attached to the socket 6, the lamp 4 is attached to the socket 6 and then the shade 5 is fitted and fixed in the shade receiver 3.

[Problems to be solved by the device]

However, the structure of the conventional spring piece 9 is such that the spring piece 6 can flex freely even if the shade 5 is fixed to the shade receiver 3 as shown in FIG. Therefore, the lamp 4 can be pulled out without removing the shade 5, and the user may forcibly replace the lamp 4 without removing the shade 5, and the tip of the lamp 4 may hit the inner surface of the shade 5 to damage the lamp 4. was there. There is a problem that when a large impact force is applied to the lamp part such as the shade 5 from the outside, the lamp 4 may come off and the lamp 4 may be damaged.

The present invention has been provided in view of the above points, and prevents the lamps from coming off even when a large force is applied to a shade or the like, and also makes it clear the replacement order of the lamps to prevent the lamp from cracking due to misuse. It is intended to provide a lighting fixture for the purpose of prevention.

[Means for Solving the Problems]

The present invention provides a socket with a spring piece which elastically engages with a protrusion protruding from the base of a lamp, and urges the portion of the shade receiving member located outside the spring piece to the outside when the lamp is attached or detached. Forming a notch for escape of the spring piece, and covering the notch with the base of the shade so that the spring piece comes into contact with the inner surface of the shade before bending to the position where the lamp comes off through the notch Is.

[Action]

Then, when the shade is attached to the shade receiver, the spring piece of the socket abuts the inner surface of the shade through the notch of the shade receiver, and the spring piece is regulated by restricting the bending of the spring piece. Prevent the engagement with the protrusion of the mouthpiece,
The lamp can be removed after removing the shade.

〔Example〕

Hereinafter, embodiments of the present invention will be described with reference to the drawings. Third
In FIGS. 5 to 5, a shade receiver 3 is rotatably provided on an upper portion of an arm 2 rotatably provided on the instrument body 1. Notches 12 are formed on the upper and lower sides of the shade receiving tool 3 for allowing the spring pieces 9 of the socket 6 to escape when the spring 6 is bent. Further, elastic claw portions 13 for fitting with the shade 5 are formed on both side surfaces of the shade receiving member 3, respectively.

Next, the operation sequence when replacing the lamp will be described. Pull out the shade 5 in the direction of the arrow in FIG. 3, hold the tip of the lamp 4 in the direction of the arrow, and then pull out the socket 6
Remove the lamp 4. Similarly, at the time of mounting, after inserting the lamp 4 into the socket 6, the shade 5 is attached to the shade receiver 3.

A detailed description of the above operation will be described with reference to FIGS. 1 and 2. That is, as shown in FIG. 1, when the shade 5 is fitted in the shade receiver 3, the spring piece 9 of the socket 6 is located at the position of the notch 12 of the shade receiver 3 and When the lamp 4 is detached with the spring attached, the spring piece 9 bends, but the tip of the spring piece 9 hits the inner surface of the shade 5, and the lamp 4 cannot bend until it comes off. Therefore, the lamp 4 cannot be removed from the socket 6 without removing the shade 5.

When the lamp 4 is removed, the lamp 4 is removed from the socket receiver 3 and the lamp 4 is removed from the socket 6.
When the spring piece 9 is pulled out from the spring piece 9, the spring piece 9 bends, the tip of the spring piece 9 pops out from the notch 12 of the shade receiving device 3, and the lamp 4 can be removed from the socket 6. As described above, the lamp 4 can be attached and detached only when the shade 5 is removed.

[Effect of device]

As described above, the present invention provides a socket with a spring piece that elastically engages with a protrusion that is provided on the base of a lamp, and attaches or detaches the lamp to or from a shade receiving portion located outside the spring piece. Forming a notch for escape of the spring piece that urges outward, the notch at the base of the shade so that the spring piece contacts the inner surface of the shade before bending to the position where the lamp comes off through the notch. When the shade is attached to the shade receiver, the spring piece of the socket comes into contact with the inner surface of the shade through the notch of the shade holder and restricts the bending of the spring piece. In order to prevent the spring piece from disengaging from the protrusion of the base so that the lamp can be removed after removing the shade, the procedure for lamp replacement is standardized. Can prevent misuse by users Also, no problems lamps cracks due to misuse, Moreover, even if an external shock to the lamp unit, such as a shade, because light is not released from the socket,
Since it is safe and only the notch is formed in the shade receiver, it is possible to obtain an effect that the order of lamp replacement can be easily made constant at a low cost.
