DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is a perspective view showing a packaging state of a lamp for lighting equipment using the lamp packaging part according to the present embodiment. In FIG. 1, reference numeral 21 denotes an open lower surface. It is drawn with the opening facing upward.) The main body of the appliance, in which two lamp holders 22 are provided.
Are mounted, and two lamp sockets 24 which are individually opposed to the respective lamp holders 22 are mounted. The lamp socket 24 is detachably connected to a base of a single-base fluorescent lamp 25 whose discharge path is bent in a U-shape.
The opposite end 25 a of the base 5 is detachably supported by the lamp holder 22.

The lamp holder 22 is formed by bending a band-like metal plate having a spring property. As shown in FIGS. 4 and 5, a pair of curled ends 26 and a pair of holders 27 are provided. And a base portion 28.

The pair of curled ends 26 are connected to the fluorescent lamp 2.
No. 5 is a portion having a substantially arc-shaped cross section that faces at an interval B smaller than the width A of the glass tube portion 25b, and the opposite surface is a curved concave surface 26a. A pair of holder portions 27
Is a portion which has a circular cross section along a part of the outer periphery of the glass tube portion 25b and elastically sandwiches the glass tube portion 25b, and a curled end portion 26 is integrally connected to one end thereof. The base portion 28 is a portion integrally connecting the other ends of the holder portions 27, and the lamp holder 22 is connected to the reflection plate 23 from below by a screw passing through the center.

The fluorescent lamp 25 is a lamp socket 2
The lamp packaging part 31 according to the present embodiment is packaged in a state in which it is mounted in the fixture main body 21 via the lamp holder 22 in the posture at the time of use together with the lamp holder 4.

The lamp packaging part 31 is formed of a strip-shaped plate made of a packaging material such as a corrugated cardboard or a press board. As shown in FIGS.
A pair of through holes 33 and a pair of seesaw plate portions 34 are provided.

The main plate portion 32 is formed at a portion located at the center of the strip-shaped packaging material.
5b so as to overlap in the width direction. The pair of through holes 33 are provided at both ends in the longitudinal direction of the main plate portion 32, respectively, and are formed by cut and raised traces of an engagement tongue piece portion described later. As shown in FIG. 4, the interval C between the inner edges of the pair of through holes 33 is smaller than the shortest interval B between the pair of curled ends 26, and the outer edge of the pair of through holes 33. The interval D between them is larger than the interval E between the tips of the pair of curled ends 26.

The seesaw plate portion 34 is formed of an engaging tongue piece 35 and an operation piece 36, and is provided at both longitudinal ends of the main plate 32 via folds 37, respectively.
It is bendable with a seesaw operation centered at 7. The fold 37 is formed by a half cut extending from the outer edge of the through hole 33 in the width direction.

The engaging tongue piece 35 has, for example, the same shape as the through hole 33, and is cut and raised above or below the main plate 32 by the seesaw operation. The operation piece portion 36 is located on the opposite side of the engagement tongue piece portion 35 from the fold line 37 and has the same width as the main plate portion 33.

Next, a procedure for packaging the fluorescent lamp 25 attached to the fixture main body 21 in the posture at the time of use with the lamp packaging component 31 having the above-described configuration will be described below.

First, with respect to the lamp packaging part 31 before bending shown in FIG. 3 (A), the pair of seesaw plate portions 34 are folded along the folds 3 as shown by arrows in FIG. 3 (A).
By bending upward around the center 7, the operation piece 36 is bent upward at a substantially right angle with respect to the main plate 32 through an intermediate state shown in FIG. Then, at the same time, as shown in FIG. 4, the engaging tongue piece 35 of the seesaw plate 34 is cut at a substantially right angle to the lower part of the main plate 32, and the through hole 33 formed by the cut and raised trace is formed. Are formed at both ends of the main plate portion 32, respectively.

Next, while arranging the lamp packaging component 31 so as to overlap the glass tube portion 25b of the fluorescent lamp 25 from the upper side in the thickness direction (see the arrow in FIG. 4), the lamp holder 22 is inserted into the pair of through holes 33. The curl end 26 is inserted. Thereby, the engagement tongue piece 35 is positioned so as to face the curved concave surface 26 a of the curled end 26.

Thereafter, as shown by the arrow in FIG. 3B, the operation piece portions 33 of the pair of seesaw plate portions 34 are pushed down, and the seesaw plate portions 34 are bent around the folds 37, thereby forming the lamp packaging parts 31. Flip the whole down. Then, through the intermediate state shown in FIG. 3C, the operation piece 36 of the seesaw plate 34 is moved to the main plate 32 as shown in FIG.
On the lower side, the engagement tongue pieces 35 are respectively located above the main plate part 32.

By such an operation, the seesaw plate portion 34
Involves a seesaw operation centered on the fold 37, so that the engaging tongue piece 35 located opposite the curved concave surface 26a of the curled end 26 rises up and passes through the through hole 33 from the lower side to the upper side. Thereafter, the distal end of the engaging tongue piece 35 is engaged with the curved concave surface 26a while elastically deforming the curl end 26 in the direction to reduce the interval B.

With this engagement, the main plate portion 32 is
5b, the further seesaw operation is hindered, and as shown in FIGS. 1 and 5, the contact point between the main plate portion 32 and the glass tube portion 25b, the engaging tongue piece portion 36, the curved concave surface 26a, The lamp packaging component 31 is fixed in an arrangement such that it traverses the glass tube portion 25b in the width direction with the contact point as a fulcrum.

The lamp packaging component 31 attached over the pair of curled ends 26 in the above-described procedure prevents the pair of curled ends 26 of the lamp holder 22 from expanding in directions away from each other with elastic deformation. Therefore, the lamp holder 2 which can be elastically deformed, for example, when transporting the appliance.
The distance B between the pair of curled ends 26 of the two fluorescent lamps 2 is increased irrespective of the impact applied during transportation.
5 can be prevented from being accidentally detached from the lamp holder 22.

When unwrapping the fluorescent lamp 25 by the lamp packaging part 31, the pair of seesaw plate parts 34 are bent around the folds 37 in the direction indicated by the arrow in FIG. Flip the whole to the top,
The operation piece 36 is placed above the main plate 32 and the engagement tongue 3
After each of the lamp packages 5 is positioned below the main plate portion 32, the entire lamp packaging component 31 may be pulled upward from the pair of curled ends 26.

As described above, when the lamp packaging component 31 is attached to and detached from the lamp holder 22, the pair of seesaw plate portions 34 are turned upside down around the fold 37 so as to perform a seesaw operation, and curled into the through hole 33. Since the operation can be performed by inserting and removing the end portion 26, the trouble of attaching and detaching the end portion 26 is small. Therefore, the operation of packaging the fluorescent lamp 25 with the lamp packaging component 31 and the operation of unpacking the fluorescent lamp 25 can be facilitated.

Furthermore, since the fluorescent lamp 25 can be packaged while being supported by the lamp holder 22 and the lamp socket 24, the number of packaging parts to be put in and out of the fixture main body 21 in packaging the entire lighting fixture is reduced. In addition to the above, the time and effort for mounting and dismounting the fluorescent lamp 25 are not required, so that the time required for packaging the entire lighting fixture can be reduced, and the time for unpacking the entire lighting fixture can be reduced.

The lamp packaging component 31 only needs to have a size enough to be attached to the lamp holder 22, and can be formed by a single plate. Therefore, the fluorescent lamp 25 can be packaged as described above with a very small amount of packaging material.

As described above, since the fluorescent lamp 25 can be packaged by using the single and small lamp packaging part 31 by using the lamp holder 22, the packaging time is reduced as described above. Together with this, the packaging cost can be reduced. Although the lamp packaging component 31 is discarded after its use, the amount of the packaging waste material can be considerably reduced as compared with the conventional one for the reasons described above.

The present invention is not limited to the above embodiment. For example, a pair of through holes 33 provided in the main plate portion 32
Alternatively, both ends of one hole provided continuously in the main plate portion 32 may be used. Further, the seesaw plate portion 34 may be provided only at one end of the main plate portion 32, and in this case, the through-hole 32 formed by cutting and raising the engaging tongue piece portion 35 of the seesaw plate portion 34 is one. Needless to say, the other through holes provided in the main plate portion 32 are
The second curl end 26 may be formed to have substantially the same size as the cross section thereof.

[0035]

As described in detail above, the lamp packaging part of the present invention is mounted on a pair of curled ends provided in a lamp holder for holding a single-type fluorescent lamp together with a lamp socket. Since the lamp is packaged in a state where it is mounted in a used position, and when the lighting equipment is transported, for example, the pair of curled ends of the lamp holder are prevented from expanding in a direction away from each other with elastic deformation. By the attachment, the possibility that the fluorescent lamp comes off from the lamp holder can be eliminated. The lamp packaging component only needs to be large enough to be attached to the lamp holder, and can be formed by a single plate. Therefore, the fluorescent lamp can be packaged with an extremely small amount of packaging material, and the packaging cost can be reduced. In addition, the lamp packaging part packaging and the packaging can be performed with only the labor of bending the seesaw plate so as to perform the seesaw operation around the fold, in accordance with the labor of inserting and removing the through hole of the main plate part from the curl end. Can be solved and these tasks can be facilitated.
