JP 2002-370784 A

  The problems to be solved by the present invention include a light emitting portion having a pair of electrodes inside, a light emitting tube comprising sealing portions at both ends of the light emitting portion, and a base attached to an end portion of the sealing portion. In a lamp packing box having a pair of lamp supports inside the outer box body, an excessive load is applied to the arc tube, particularly the sealing part, due to vibration and shock during lamp transportation. An object of the present invention is to provide a structure capable of preventing the arc tube from being damaged without being hung.

  In order to solve the above-described problems, in the lamp packaging box according to the present invention, the lamp supporter supports an exposed portion that is a light emitting portion side portion from a base in a sealing portion of the arc tube. And

In addition, the lamp support is made of a block-shaped molded body having a buffer structure and has a through hole into which the sealing portion exposed portion is inserted at the center thereof.
Further, the lamp supporter includes a fixed portion that holds the outer periphery of the exposed portion of the sealing portion, and a buffer portion that supports the fixed portion, and the fixed portion is more than the buffer portion. It is characterized by low buffering properties.
Further, the lamp supporter includes an upper molded body including a fixing portion that grips an outer periphery of the sealing portion exposed portion and a buffer portion that supports the fixing portion, and the fixing portion is more than the buffer portion. It is characterized by low buffering properties.
Further, the lamp supporter includes an upper molded body including a fixing portion that grips an outer periphery of the exposed portion of the sealing portion and a buffer portion that supports the fixing portion, and the upper / lower fixing portion is a binding band. The upper / lower fixing part is fixed and fixed in a state where the sealing part exposed part is sandwiched between the upper / lower fixing parts.
In the lamp support, the upper / lower fixing part includes a binding band, and the upper / lower fixing part is fixed and fixed in a state where the sealing part exposed part is sandwiched between the upper / lower fixing parts. And
In the lower molded body of the lamp support, the fixed portion is fixed to the buffer portion, and the fixed portion of the upper molded body is rotatably attached to the fixed portion of the lower molded body. It is characterized by.

  The lamp support is formed of a block molded body having a buffering property, and the molded body is formed with a slit narrower than the diameter of the exposed portion of the lamp sealing portion opened on the upper surface, and at the bottom of the slit. A support opening having a diameter substantially the same as the diameter of the exposed portion of the sealing portion is formed.

  Further, the lamp support is composed of a pair of upper and lower molded bodies, the molded body is a plate-shaped molded body having a substantially trapezoidal cross section, and a recess is formed on a horizontal surface of the plate-shaped molded body, The sealing part exposed part of the said lamp | ramp is clamped between the recessed parts of an upper and lower molded object, It is characterized by the above-mentioned.

According to this invention, since the lamp supporter supports the exposed portion, which is a portion on the light emitting portion side of the base in the sealing portion of the lamp, the distance from the lamp support portion to the light emitting portion is reduced and supported. The bending moment acting on the portion is reduced, it is sufficiently resistant to vibration and impact during transportation, and the arc tube has no effect of breakage such as cracks.
In addition, since the lamp support is made of a molded product having a split structure, the sealing part of the lamp is held around the entire periphery, so that it is safe even if the top and bottom of the exterior box are upside down. Can support the lamp.

In addition, the lower molded body of the lamp supporter is composed of a fixed part having a low buffering property that holds the outer periphery of the exposed part of the sealing part, and a buffering part having a high buffering property that supports the fixed part. Compared to the case where the lamp sealing part is directly supported by the integrally molded body, the fixing part which is a contact part with the exposed part of the sealing part is the material of the deformation of the support during storage due to the lamp weight. Since it can suppress from a characteristic and a buffer part supports a lamp | ramp via a fixing | fixed part, force is disperse | distributed and it can suppress. Therefore, compared with the case where the lamp sealing part is directly supported by the integrally molded body, the clearance between the upper molded body and the exposed part of the sealing part is maintained during storage while maintaining equivalent or better buffering properties. Can be suppressed.
Further, both the upper / lower molded bodies of the lamp supporter are constituted by a fixing portion having a low buffering property that holds the outer periphery of the exposed portion of the sealing portion and a buffering portion having a high buffering property that supports the fixing portion. Thus, the entire periphery of the exposed portion of the sealing portion of the lamp can be covered with the fixing portion, and as a result, the lamp support can be prevented from being deformed and the cushioning property can be improved regardless of the orientation of the packaging box during lamp storage. It becomes possible.

  The upper / lower fixing part of the upper / lower molded body of the lamp support is provided with a binding band, and the upper / lower fixing part is held in a state where the sealing part exposed part is sandwiched between the upper / lower fixing parts. By tightly fixing, the clearance between the sealing portion and the fixing portion can be minimized. Furthermore, since the upper / lower cushioning part is deformed at the moment when the drop impact occurs, a clearance is generated between the upper molded body and the lower molded body, and the lamp may be displaced from a predetermined position at that moment. However, when the upper / lower fixing part is fixed and fixed, the size of the upper / lower fixing part that is fixed and fixed is sufficiently large with respect to the size of the generated clearance, so that the deviation hardly occurs.

  In addition, since the fixing portion of the upper molded body is rotatably attached to the fixing portion of the lower molded body, after the lamp sealing portion is placed on the lower fixing portion, the upper fixing body is rotated and covered. Then, by tightening the binding band, the lamp can be supported easily and firmly by a simple operation.

  In addition, since a slit narrower than the lamp sealing portion opened on the upper surface of the block molded body constituting the lamp support is formed and a support opening is formed on the bottom thereof, the lamp sealing portion is press-fitted into the slit. Then, the lamp sealing portion exposed portion can be supported in the opening only by a simple operation of entering the supporting opening in the bottom portion.

  The lamp support is composed of a pair of upper and lower plate-shaped molded bodies having a substantially trapezoidal cross section, and the lamp-sealed portion exposed portion is sandwiched between recesses formed on the horizontal surface of the plate-shaped molded body. Therefore, the molded body having a trapezoidal cross section can obtain a high shock-absorbing property and flexibility by its both leg portions, and the vibration and impact to the lamp can be greatly reduced.

As shown in FIG. 1, the lamp packaging box 1 of the present invention includes an exterior box 2 and a lamp support 3 provided therein.
The lamp support 3 is composed of an upper molded body 4 and a lower molded body 5 having a two-part structure made of a cushioning material, for example, a foamed plastic material such as polyethylene or polyurethane.
As shown in FIG. 2, the upper molded body 4 and the lower molded body 5 are formed with half-shaped through holes 6a and 6b, respectively, and the through hole 6 is formed by both of them.
In this embodiment, as shown in the figure, the upper molded body 4 of the lamp support 3 is fixed to the back surface of the opening / closing lid 2a of the outer box 2 with an adhesive or the like. When the lamp 20 is placed on the half through-hole 6b of the lower molded body 6 and then the lid 2a is closed, the upper molded body 4 is closed on the lower molded body 5 and the half of the upper molded body 4 is split. The through hole 6 is formed by the through hole 6 a and the half through hole 6 b of the lower molded body 5, and the lamp 20 is sandwiched between the upper / lower molded bodies 4 and 5.
At this time, as shown in FIG. 3, the through hole 6 has an exposed portion (hereinafter referred to as “sealing”) that is a portion closer to the light emitting portion 22 than the base 26 in the sealing portion 23 of the discharge lamp 20 shown in FIG. 23a) is inserted, and the sealing portion exposed portion 23a is supported by the lamp support 3.

FIG. 4 shows another embodiment of the lamp support 3. In this embodiment, the lower molded body 5 of the lamp support 3 includes a fixing portion 5 a and a buffer portion 5 b. These are both made of a material having a buffering property, but the buffer part 5b is made of a material having a higher buffering property.
As the buffer material constituting the fixing part 4 and the buffer part 5, foamed plastic is adopted, for example, polyethylene, polypropylene, polyurethane, etc., preferably polyethylene, but as described above, the buffer part 5b is the fixed part. It is selected from a material having a larger buffer than 5a.
For example, the fixing portion 5a is formed of a cushioning material equivalent to the upper and lower molded bodies 4 and 5 of the embodiment shown in FIGS. 1 to 3, and the buffering portion 5b is made of a material having a larger cushioning property, that is, a softer material. Is done.

FIG. 5 shows a partial development view of the embodiment of the lamp support 3 of FIG.
In the figure, the upper molded body 4 is formed with a half-arc-shaped through-hole 6a, while the fixing portion 5a of the lower molded body 5 is formed with a half-shaped arc-shaped through-hole 6b. In both cases, a through hole 6 is formed.
At the time of individual packaging, the exposed portion 23a of the sealing portion 23 of the lamp 20 is placed on the arc-shaped through hole 6b of the lower molded body 5, and the arc-shaped through hole 6a of the upper molded body 4 is covered from above, The exposed portion 23 a is supported between the upper / lower molded bodies 4 and 5.
Thereby, since the lamp 20 is supported by the fixing portion 5a of the lower molded body 5, the amount of sinking of the lower molded body due to the weight of the lamp is suppressed, and there is no clearance between the upper molded body, The sealing portion exposed portion 23a can be firmly fixed.
Further, the upper molded body 4 can be made of a material having a high buffering property, and can be accurately fitted to and supported by the shape of the lamp sealing portion exposed portion 23a. Further, vibration and impact can be absorbed together with the lower buffer portion 5b.

FIG. 6 shows another embodiment of the lamp support 3. In this embodiment, the upper molded body 4 is composed of a fixed portion 4 a and a buffer portion 4 b, similar to the lower molded body 5. The buffer part 4b is also made of a material having a larger buffer property than the fixed part 4a.
In this embodiment, by fixing the entire circumference of the sealing portion exposed portion 23a of the lamp 20 with the fixing portions 4a and 5a, the fixing of the sealing portion exposed portion 23a becomes firm and stable, and the fixing portion 4a 5a is supported by the buffer parts 4b and 5b, which are more buffering than the above, so that vibrations and shocks during transportation are absorbed by the buffer parts 4b and 5b, preventing direct action on the lamp 20. it can.
Therefore, regardless of the orientation of the packaging box during lamp storage, it becomes possible to prevent the lamp support from being deformed and to improve the buffering property, and even when transporting the lamp in a standing state during transportation, it can be used in all directions. It can be firmly supported and will not be too staggered by vibrations.

FIG. 7 shows still another embodiment of the lamp support 3. In this embodiment, a binding band 10 is provided around the upper and lower solid portions 4a and 5a in the embodiment shown in FIG.
The details are shown in FIG.
In FIG. 8, a binding band 10 is wound around the outer peripheral surface so as to wrap around the fixing portion 4a of the upper molded body 4 and the fixing portion 5a of the lower molded body 5.
FIG. 9 shows a developed view thereof. The binding body 10 is attached to the outer peripheral surface of the fixing portion 5a of the lower molded body 5 by gluing or the like, and the lower fixing portion 5a sandwiches the binding body 10 with the lower buffer portion. It is fixed to 5b.
On the other hand, the fixed portion 4a of the upper molded body 4 is rotatably attached to the fixed portion 5a of the lower molded body 5. In this embodiment, the upper fixing portion 4a is attached to the binding band 10 by gluing or the like, and the binding band 10 is rotatable with respect to the lower fixing portion 4b. Of course, it may be rotatably connected by other means.
The binding band 10 is formed of a hollow structure plate having a thickness of about 1 to 15 mm formed from, for example, a thermoplastic resin.
The upper / lower fixing portions 4a and 5a are formed with semicircular arc-shaped through holes 6a and 6b, and the through holes 6 are formed by these half-shaped through holes 6a and 6b.

The packing procedure in this embodiment is shown in FIG. (A) The upper fixed portion 4a of the upper molded body 4 is rotated and deployed with respect to the lower molded body 5 and is in an open state. The sealing portion exposed portion 23a of the lamp 20 is placed on the half through hole 6b of the lower fixing portion 5a from above (1).
(B) Then, the upper fixing portion 4a is rotated (2) so that the sealing portion exposed portion 23a of the lamp 20 is pressed from above, and the sealing portion is sandwiched between the fixing portions 4a and 5a. . Then, the binding band 10 is tightened to bind both the fixing portions 4a and 5a (3). The binding band 10 is provided with a fixing means 11 such as a hook-and-loop fastener or a snap, for example, and the binding band 10 firmly binds the fixing portions 4a and 5a.
(C) Thereafter, the buffer portion 4b is covered from above the upper fixing portion 4a of the upper molded body 4 (4).

FIG. 11 shows a state in which the lamp 20 is supported by the lamp support 3 in this way. Between the upper / lower fixed portions 4a and 5a of the upper / lower molded bodies 4 and 5 of the lamp support 3, a sealing portion exposed portion 23a of the lamp 20 is sandwiched and supported.
In this embodiment, since the fixing portions 4a and 5a for fixing the sealing portion exposed portion 23a of the lamp 20 are firmly bound by the binding band 10, the support of the lamp 20 is made extremely firm. The clearance between the exposed portion 23a and the fixed portions 4a and 5a can be minimized. Furthermore, since the upper / lower buffer portions 4b and 5b are deformed at the moment when the drop impact occurs, a clearance is generated between the upper molded body 4 and the lower molded body 5, and the lamp is moved from a predetermined position at that moment. The upper / lower fixing parts 4a and 5a are fixed and fixed, so that the upper and lower fixing parts 4a and 5a fixed and fixed are sufficiently larger than the generated clearance. Therefore, it becomes difficult for deviation to occur.
The vibration during transportation or the like is absorbed and relaxed by the upper / lower buffer parts 4b and 5b and does not directly act on the lamp 20.

Incidentally, in the embodiment shown in FIG. 7, the fixing portion 4a of the upper molded body 4 does not necessarily have the same hardness as that of the lower fixing portion 5a, and the embodiment is shown in FIG.
That is, in FIG. 12, the fixing portion 4a of the upper molded body 4 is made of the same material as the buffer portion 4b. Also in this case, the periphery of the upper / lower fixing parts 4 a and 4 b is bound by the binding band 10.
Thereby, since the upper fixing part 4a has a soft cushioning property, it fits well along the shape of the sealing part exposed part 23a of the lamp and is tightened by the binding band 10.

FIG. 13 shows another embodiment. 6 to 12, the upper / lower fixing portions 4a and 5a in the lamp support 3 are provided so as to cover only the sealing portion exposed portion 23a of the lamp 20. In the case of 13, the fixing portions 4a and 5a cover not only the sealing portion exposed portion 23a but also the entire sealing portion 23 including the base 26. Even in this embodiment, the buffer portions 4b and 5b as the support means of the lamp 20 support the sealing portion exposed portion 23a of the lamp 20.
If it carries out like this, since the sealing part end of the lamp | ramp 20 is covered including the nozzle | cap | die 26 by the upper / lower fixing | fixed part 4a, 5a, these parts will be protected entirely.

FIG. 14 shows still another embodiment. In the case of this embodiment, a configuration in which the windshield 13 is attached to one sealing portion 23 of the lamp 20 so that the cooling air does not hit the sealing portion 23 is employed.
In this embodiment, in the sealing portion 23 on the side where the windshield 13 is attached, the exposed portion is virtually absent, so the other-side sealed portion exposed portion 23a is supported by the lamp support 3. The side where the windshield 13 is provided is supported by the base 26.
Even in this case, at least on the side supported by the sealing portion exposed portion 23a, the distance from the support point (lamp support 3) to the light emitting portion 22 is smaller than that of the prior art, and resistance to vibration and impact is increased.

In the embodiment of FIGS. 1 to 14, the lamp support 3 is composed of a block molded body having a divided structure. However, in FIG. 15, the block molded body is not a divided structure but an integral structure. It is shown.
