DEVICE FOR LIGHTING UP FLAGS

Abstract: Device to be used at flag poles for lighting up the flag, characterized by a translucent tube (2) which encloses the light fittings (7) and which is arranged to form a part of the top of the flag pole.

Description: Device for lighting up flags The claimed invention relates to a device for lighting up flags. The invention is characterized mainl by a translucent tube which encloses light fittings and which is arranged to form a part of the top of a flagpole. In describing the present invention, reference will be made to the accompanying figures of drawings in which: fig. 1 is a longitudinal section through the device applied on a tubular flagpole; fig. 2 is a corresponding longitudinal section through the device applied on a> assive flagpole. The device according to the invention consists of a preferably to the outercountur of the top of the flagpole 1 connecting tube 2 made of translucent material. The tubular flagpole showed in fig. 1 can be made of for example metal or plastic. The tube 2, which forms the top of the flagpole, is at its lower end supplied with a holder 3 carried out with a threaded lower part 4, which cooperates with an interior thread in the upper part of the pole 1. The tube 2 supports at its upper end a flagpoleball 5 which is carried out with a holderpart 6. Between the holders 6 and 3 extends a fluorescent tube 7 in the whole longitudinal section of the tube 2. The electricity supply for the fluorescent tube 7 is transsmitted through a cable 8 inside the flag¬ pole 1. Referring to fig. 2, where the flagpole 1 is made of massive material, the lower holder 9 is carried out with a sleeve 10 which surrounds the upper part of the flagpole 1. The holder 9 also supports a fastening screw 11, which, according to fig. 2, is lowered in the massive pole 1. In other respects the device according to fig. 2 is carried out in the same way as showed in fig 1. The electricity supply for the fluorescent tube 7 is however arranged with a cable 12 on the outside of the flagpole 1. Through the present invention an efficient lighting of the flag is obtained without any shadows thrown from the pole on the flag. Another advantage is, compared with other devices for lighting up flags, that drying of a wet flag is made possible thanks to emitted heat from the fluorescent tube 7. The device is also, simple to arrange. The invention is not restricted to the description above or to the drawings, but can vary within the limits of following claims. The translucent tubular part of the flagpole has preferably a length which mainly corresponds to the width of the flag for example at least 0.5m, l.Om, 1.5m or 2.0m. A suitable maximum length can be 1.5m, 2.0m or 2.5m. The diameter at the lower part of the translucent tube can be chosen in that way that the lower part surrounds the upper part of the flagpole for example overlapping at least 5cm, 10cm or 20cm and preferably maximum 50cm or 30cm. The lower part of the translucent tube can be carried out with about the same outer diameter as the nearby nontranslucent part of the flagpole, whereby these both parts can pre¬ ferably be connected with an on the inside placed tubular reinforcing part, for example a metaltube preferably a steeltube, which extends a suitable length through the lower part of the translucent tube and the upper part of the nontranslucent part of the flagpole, for example at leastδcm, 10cm or 20cmj preferably maximum 50cm, 30cm or 15cm. The lightsource, for example a fluorescent tube, is carried out with a length including the longer part of the translucent tube of at least 50%, 75% or90% of the tubes length, from the end of the nontranslucent part of the flagpole, including an eventually mounted reinforcing tube. The translucent part can also be supplied with a grating of the type which is used to neutralize dazzling in the fluorescent tube fittings, preferably with a horisontal directed gratingele ent as plates or the like for pre¬ venting that an observer standing on the ground can di¬ rectly see and be dazzled by the lightsource. It is even possible that inside the translucent part arrange some form of a reflector, eventually partly translucent, which direct the rays of the lightsource towards the flag. The reflectors can be turnable and for example connected with a weathercock at the top of the flagpole, which adjusts the reflector in the way that the rays are directed to¬ wards the flag in the direction of the wind. The device can also be carried out with a lighted up emblem arranged at the top of the flagpole above the translucent part. The lighting of the emblem can be effected by the lightsource for the flag or by a separate light. Such an arrangement is shown in fig 3.
