Description

  The present invention relates to an illumination tube cover including a pair of side covers that face a side surface of an illumination tube such as a fluorescent tube and sandwich the illumination tube from both diametrical sides.

  Conventionally, a fluorescent lamp is often composed of a fluorescent tube and a fluorescent tube cover that covers a part of the side surface of the fluorescent tube. The fluorescent tube cover generally includes a side cover that faces the side surface of the fluorescent tube and sandwiches the fluorescent tube from both sides in the diameter direction.

On the other hand, as described in, for example, Patent Document 1, as a fluorescent tube, there is a side base type fluorescent tube in which a base is provided on a side surface of a fluorescent tube and a base pin projects in a direction perpendicular to the longitudinal direction of the fluorescent tube. Are known. Such attachment and removal of the side cap type fluorescent tube from the socket (insertion and withdrawal of the cap pin into the socket) is performed by pushing or pulling in the direction in which the cap pin extends by holding the fluorescent tube. Needs to be pulled out by inserting a finger on both sides in the diameter direction of the fluorescent tube or further on the back side (socket side) from both sides in the diameter direction.

  By the way, when installing fluorescent lamps in various rooms, show windows, etc., there are cases where it is desired to install slim fluorescent lamps having a narrow width (the length in the direction perpendicular to the longitudinal direction of the fluorescent tube) for various reasons. .

  In such a case, it is necessary to reduce the width of the fluorescent tube cover (the length in the direction perpendicular to the longitudinal direction of the fluorescent tube) (slimming of the fluorescent lamp). When it is made smaller, the distance between the fluorescent tube and the fluorescent tube cover is inevitably, that is, between the side cover and the fluorescent tube located on both sides in the diameter direction of the fluorescent tube and facing the side of the fluorescent tube. Since the distance becomes short and a finger cannot be put there, and it becomes difficult to attach and detach the above-described side cap type fluorescent tube, there is a problem that there is a limit to slimming down the fluorescent lamp.

  The above problem is conspicuous in the case of a side cap type fluorescent tube, but in the case of a normal type fluorescent tube in which a cap is provided on both ends of the fluorescent tube in the longitudinal direction and the cap pin protrudes in the longitudinal direction of the fluorescent tube. It exists as well. Moreover, the said problem exists not only in a fluorescent tube but in the illuminating lamp using the illumination tube of all kinds of light sources, such as an incandescent illumination tube and an LED illumination tube.

  In view of the above circumstances, an object of the present invention is to provide an illuminating tube cover that enables further slimming of an illuminating lamp such as a fluorescent lamp and can easily attach and detach an illuminating tube.

FIG. 6 is a cross-sectional view taken along line VV in FIG. 1, particularly showing a center cover and a socket, and FIG. 7 is a view showing a side cap type fluorescent tube. It is. In the following description, “front” and “rear” mean directions indicated by arrows in FIG.

  The illumination tube cover shown in FIGS. 1 to 5 is a fluorescent tube cover used for the side cap type fluorescent tube shown in FIG. The side tube type fluorescent tube 1 is an elongated fluorescent tube, and includes a base 2 attached to the side surface 1a of the fluorescent tube in the vicinity of both ends in the longitudinal direction of the fluorescent tube 1, and from the base 2 to the longitudinal direction of the fluorescent tube 1 The cap pin 3 protrudes in a direction perpendicular to the base.

  As shown in FIGS. 1 to 5, the fluorescent tube cover 10 is a cover to which an elongated fluorescent tube 1 is attached and covers the fluorescent tube 1 from both sides in the diameter direction, and is fixed to the installation surface F of the fluorescent lamp. A base body 11 and a pair of side covers 12 that are rotatably supported by the cover base body 11 and that are located on both sides in the diameter direction of the fluorescent tube 1 and have facing portions 12a that face the side surfaces of the fluorescent tube 1; Cover end plates 13 provided at both ends in the longitudinal direction of the fluorescent tube 1 are provided.

  The cover base 11 has a U-shaped cross section composed of a base bottom plate 11a fixed to the installation surface F and a pair of base side plates 11b extending upward from both ends of the base bottom plate 11a, and the direction in which the fluorescent tube 1 extends. It extends for a long time. A support portion 11c for rotatably supporting the side cover 12 is formed at the upper end portion of the base body side plate 11b.

  In the cover base 11, a base 20 extending in the longitudinal direction of the cover base is fixed on the base bottom plate 11a, and a cap pin 3 of a fluorescent tube is inserted into both ends of the base 20 in the longitudinal direction. And a bracket 22 that clamps the cap 3 of the fluorescent tube and prevents the fluorescent tube 1 from falling off. The socket 21 has a pin insertion hole 21a on the upper surface side. The base 20 is provided with a center cover 23 extending between the sockets 21 extending in the longitudinal direction of the base 20. The center cover 23 is fixed to the base 20 through a support 24.

  The pair of side covers 12 are located on both diametrical sides of the fluorescent tube 1 and are provided with facing portions 12a facing the side surfaces of the fluorescent tube 1, and a set position indicated by a solid line and a retracted position indicated by a two-dot chain line in FIG. Is supported by the cover base 11 so as to be rotatable in the direction of arrow A between the two positions. Specifically, the side cover 12 includes a facing portion 12a and a side piece portion 12b, and the side piece portion 12b is rotatably supported by a base portion 12c on a support portion 11c of the cover base. The fluorescent tube 1 extends from the base 12c toward both sides in the diameter direction of the fluorescent tube 1 so that the facing portion 12a is located behind the fluorescent tube 1 from the tip of the side piece 12b. The side surface 1a of the fluorescent tube cover faces the side surface 1a and extends toward the center in the width direction of the fluorescent tube cover (a direction perpendicular to the longitudinal direction of the fluorescent tube).

  As shown in FIG. 1, FIG. 2, etc., the side cover 12 has a tip (tip of the facing portion) 12 d abutting against the side surface of the center cover 23 when positioned in the set position. A portion corresponding to the socket 21 of the side cover 12 is formed with a notch 12e to avoid buffering with the socket 21 when it is rotated to the set position.

  The support portion 11c formed on the substrate side plate 11b is formed by a fitting groove 11d that opens on the outer surface of the substrate side plate 11b and extends in an arc shape on the inside and an upper surface near the opening of the fitting groove 11d. The base part (base part of the side piece part) 12c of the side piece cover 12 is curved in an arc shape inside, and the arc shaped base part 12c is fitted in the fitting groove 11d. .

  Further, the base plate 11b of the cover base is formed with a spring receiver 14 above the support portion 11c and a spring receiver 15 at the tip of the side cover 12, so that the plate spring 16 extends upward. One end is locked to the cover base spring receiver 14, and the other end is locked to the side cover spring receiver 15, and is provided between the spring receivers 14, 15. A plurality of leaf springs 16 are arranged at predetermined intervals in the entire longitudinal direction of the side cover 16.

  The side cover 12 has a rotation position about the rotation fulcrum 11e as a center of rotation and a base position 12c in sliding contact with the rotation fulcrum 11e. It can be rotated between the retracted positions indicated by the dotted lines and can be positioned at both positions, and both spring receivers 14 and 15 and the leaf spring 16 constitute positioning means. More specifically, as the cover base spring receiver 14 rotates from the set position to the retracted position, the distance from the cover base spring receiver 14 to the side cover spring receiver 15 gradually decreases. The distance gradually increases from the middle, and the distance when in the retracted position is formed at the same position as the distance when in the set position.

  Further, when the side cover 12 is in the retracted position, the rear end of the base 12c of the side cover comes into contact with the rear surface of the fitting groove 11d and the rear surface functions as a stopper (see FIG. 3). Therefore, it is impossible to rotate further forward (in the direction opposite to the set position).

  Further, when the side cover 12 is in the set position, the tip 12d of the side cover abuts against the side surface of the center cover 23, and the center cover 23 functions as a stopper. Rotation in the opposite direction is impossible.

  With the above-described configuration, when the side cover 12 is in the set position, the distance between the cover base spring receiver 14 and the side cover spring receiver 15 is shortened when the side cover 12 is rotated outward from the set position. Further, the side cover 12 is positioned at the set position by the drag force of the leaf spring 16, and when the side cover 12 is in the retracted position, if the inner cover is to be rotated inward from the retracted position, the cover The distance between the base spring receiver 14 and the side cover spring receiver 15 is shortened, and the leaf spring 16 must be bent further. The side cover 12 is positioned at the retracted position by the drag of the leaf spring 16. Of course, when rotating from the set position to the retracted position and from the retracted position to the set position, the operator holds the side cover 12 by hand and further curves the leaf spring 16 with a force greater than the drag force of the leaf spring 16. By rotating, it can be rotated toward the set position and the retracted position.

  In the present embodiment, the cover base spring receiver 14 is formed at the position as described above. This is because the side cover spring when the side cover 12 rotates about the rotation fulcrum 11e shown in FIG. The distance between the curve base E indicating the rotation trajectory of the receiver 15 and the cover base spring receiver 14 and the side cover spring receiver 15 when the side cover 12 is in the set position is the radius, and the cover base spring receiver 14 is the center. It can be understood from the relationship of two curves with a curve F indicating an arc (all points on the curve F have the same distance from the cover base spring receiver 14).

  The base 2 is provided with a ridge 2a on the side surface, while the bracket 22 is provided with a leaf spring-like bracket piece 22a, and the bracket piece 22a is formed with a bent portion 22b protruding inward. When the base pin 3 of the fluorescent tube is inserted into the pin insertion hole 21a of the socket, the bracket piece 22a is pushed and widened by the base 2, and the ridge 2a is positioned behind the bent portion 22b beyond the bent portion 22b. In this state, the front surface of the ridge 2a is pressed by the rear surface of the bent portion 22b, so that the fluorescent tube 1 can be prevented from coming out of the socket 21.

  As described above, the fluorescent tube cover of the present embodiment is configured so that the side cover can be rotated between the set position and the retracted position. Therefore, when the fluorescent tube is attached or detached, the side cover is removed from the fluorescent tube. By rotating the retraction position away, the distance between the fluorescent tube and the side cover, in particular, the distance between the fluorescent tube and the facing portion of the side cover can be made sufficiently large as shown in FIG. The fluorescent tube can be attached and detached, and at the set position, the side cover can be positioned in the vicinity of the fluorescent tube without considering the attachment and detachment work, so that the fluorescent lamp can be made slim. be able to.

  The above embodiment is a cover for a side tube type fluorescent tube, but the cover of the present invention has a cap provided at both ends in the longitudinal direction of the fluorescent tube, and a cap pin protrudes in the longitudinal direction of the fluorescent tube. A cover for a normal type fluorescent tube may be used, and a cover for an illumination tube using various light sources other than a fluorescent tube, such as an incandescent lighting tube and an LED lighting tube, may be used. . That is, the cover of the present invention can be used for any lighting tube of any type or shape of light source.

  Moreover, in the said embodiment, although both of a pair of side covers are comprised so that rotation is possible, if only one side cover is rotated, illumination tubes, such as a fluorescent tube, can be attached or detached. Alternatively, only one side cover may be configured to be rotatable.
