Description

[0001]
[Industrial applications]
The present invention relates to a packaging fixture for surrounding and fixing both ends of a straight tube lighting fixture.
[0002]
[Prior art]
A conventional packaging fixture or a packaging structure using the same will be described with reference to FIG. A straight tube-type lighting device in which sockets B are attached to both ends of a device main body A having a substantially trapezoidal cross section is stored in a packaging box 35. The buffer part 45 and the fixing part 46 are combined, and the fixing tool 40 provided with the fitting notch 47 in the fixing part 46 is arranged at both ends. Practically, in consideration of physical distribution convenience, a large number of packaging boxes 35 are bound in a band or packed in another large packaging box (not shown).
Another conventional example will be described with reference to FIG. In this case, the socket B is detached, housed inside the appliance main body A, packed in a synthetic resin bag 50, and a large number of such materials are accumulated while being partitioned by the partition members 53 and 54, respectively. Next, the buffer member 52 and the reinforcing member 51 are combined and stored in the packaging boxes 36 arranged at both ends.
[0003]
[Problems to be solved by the invention]
The fixing device 40 shown in FIG. 5 has a complicated structure including a buffer portion 45 and a fixing portion 46. A simpler packaging fixture is desired.
In the system shown in FIG. 5, since each unit is stored in the packaging box 35, the straight tube-type lighting device can be safely distributed. However, it is troublesome to take out each packing box 35 at a construction site or the like where a large number of straight tube lighting fixtures are used. In addition, the amount of material of the packaging box 35 remaining after use becomes enormous, and disposal of the material becomes a burden.
The method shown in FIG. 6 is effective for reducing packaging materials and packaging volume. However, it takes time to set the socket B in the instrument main body A at a predetermined position, and the burden on work steps increases.
It is an object of the present invention to provide a simple packaging fixture suitable for certain straight tube luminaires. Another object of the present invention is to use a combination of three or more packaging fixtures, thereby minimizing the generation of packaging waste and improving the workability such as taking out the packaging box.
[0004]
[Means for Solving the Problems]
The object of the present invention is achieved as follows. Attach the socket to the instrument body normally. A part of the superposed inner bent piece of a triangular tube, which is a cardboard sheet that is inscribed on both sides of the socket and the bottom of the device main body and is superimposed on the bottom of the device main body, is bent at right angles to the bending direction of the triangular tube. A notch is continuously provided, and a cut groove is formed on the other two slopes of the triangular cylinder facing the lock piece so that the corner of the tip of the lock piece fits in, and the length of the cut groove is inserted. Assemble a packaging fixture having a length twice as long as the tip corner of the locking piece, and attach it to both ends of the lighting fixture. Next, a plurality of lighting fixtures are housed in the packaging box in a state where the mounted triangular cylinders are brought into close contact with each other by 180 ° while the corners of the locking pieces protruding from the cut grooves are fitted into the cut grooves. .
[0005]
[Action]
The lighting fixture having the packaging fixture attached to both ends is securely held without any vertical, horizontal, or vertical movement because the socket and the bottom side of the fixture body abut inside the triangular cylinder. In addition, a locking piece that stands upright in the triangular cylinder and whose tip is fitted in a notch prevents longitudinal movement, and secures an appropriate space between itself and the packaging box. Etc. can be sufficiently protected.
In addition, since the locking pieces are also fitted in the notches of the adjacent fixtures, the strength for locking the lighting fixture can be increased, and the length of the triangular cylinder can be shortened accordingly, and the packaging box can be made smaller. In addition, there is no danger that the position of the fixing tool is displaced and hinders the holding of the lighting fixture.
[0006]
【Example】
An embodiment of the present invention will be described below with reference to FIGS. A fixing fixture for packaging of straight tube lighting fixtures (A to D) having a substantially trapezoidal cross section and projecting sockets at both ends is formed as follows. One flat plate 1 is bent to form a hollow triangular cylinder 234 having surfaces 2.5 overlapped on one surface, and a part of the inner bent surface 5 constituting the overlapped surfaces 2.5, A locking piece 6 that can be bent at right angles to the bending direction forming the triangular cylinder 234 is provided in series, and the other two surfaces 3 and 4 of the triangular cylinder 234 facing the locking piece 6 are provided with locking pieces. 6 are provided with cut grooves 20 and 21 into which the front end corners 7 are fitted.
Three or more triangular cylinders 234 described above are provided, and at least one (7) of the tip corners 7 of the locking piece 6 protruding from the cut grooves 20 and 21 in one arbitrary triangular cylinder 234 is connected to another triangular cylinder. The triangular cylinders 234 described above are combined so as to fit into the cut grooves 20 and 21 at 234.
Supplement the explanation. The flat plate 1 is a corrugated board, and is provided with surfaces 2 to 5 defined by folding curves 10, 11, and 12 that divide the long sides. The two to five pieces of each surface constitute a triangular tube 234 in which the sockets B of the straight tube-shaped lighting fixtures (A to D) are at the top and the bottom D of the fixture body A is at the bottom, and the faces 2.5 are overlapped at the bottom. The bending width dimension is such that the surfaces 3 and 4 are in contact with the socket B and the bottom side portion C of the appliance body A on the inside. On the surface 5 overlapping the inside of the bottom of the triangular tube 234, a bending curve 13 is provided slightly inward from the end of the triangular tube 234 in a direction perpendicular to the bending curve 12, and the locking piece 6 having an appropriate bending height H is provided. Are connected in series.
On the surfaces 3 and 4 forming the slopes of the triangular cylinder 234, cut grooves 20 and 21 are provided at positions where the locking pieces 6 abut when the locking pieces 6 are bent vertically, into which the tip corners 7 of the locking pieces 6 fit. The length of the cut grooves 20 and 21 is set to be at least twice the tip corner 7 of the engaging piece 6 to be fitted. As shown in FIG. 2, the flat plate 1 is bent as shown in FIG. 2, and the whole is bent into a triangular cylindrical shape while fitting the corners 7 at one end of the cut grooves 20 and 21 to form a straight tube. If the end of the lighting fixture is inserted and mounted, the straight tube-shaped lighting fixture can be completely prevented from shaking.
As shown in FIG. 3, adjacent triangular cylinders 234 are 180 ° inverted, and the slopes 3 and 4 are brought into close contact with each other to combine the required number of units, and stored in the packaging box 30 as shown in the sectional view of FIG. At this time, the tip corners 7 of the locking pieces 6 protruding from the cut grooves 20 and 21 of the respective triangular tubes 234 are fitted into one ends of the cut grooves 20 and 21 of the adjacent triangular tube 234, and the locking strength is improved. As a result, the gap between the cut grooves 20 and 21 for supporting the locking pieces 6 and the ends of the surfaces 3 and 4 can be reduced, and the length of the packaging box 30 can be reduced accordingly.
Further, since the tip corners 7 of the locking pieces 6 are combined with each other so as to mesh with each other, there is no possibility that the triangular tube 234 is displaced and the holding of the straight tube-shaped lighting fixture is incomplete.
Further, since the triangular cylinder 234 has a triangular cylindrical shape, a small amount of material is used, and since the shape is strong, a relatively small fixing tool is effective.
[0007]
【The invention's effect】
According to the present invention, an inexpensive and simple packaging fixture can be obtained. In addition, a plurality of straight tube lighting fixtures with sockets attached can be collectively stored in the packaging box simply by bending one flat plate, reducing the number of steps for removing and installing straight tube lighting fixtures. In addition, since the amount of packaging material used is small, disposal processing is also easy.
By adopting a packaging method using a combination of packaging fixtures mainly composed of triangular cylinders, the dead space in the packaging box can be reduced, so that the volume is reduced by about 20% compared to the case where each unit is put in the packaging box. And transport and storage efficiency is greatly improved.
