Description

Detachable two-sided portable banner.

Technical sector

The invention should be framed in the sector of production of advertising media, communication and Promotional At present the banners are not marketed and are usually made by the user. Wood, aluminum or plastic carpentry industries They could be involved in its manufacture.

State of the art

Various types of banner are known, endowed or No of masts, and covers by people. The first and more Recent employment is usually used at the head of the demonstrations, It lacks masts and consists of a long band that does not fly.  It is carried by several people holding it directly by the upper edge that is at waist or chest height. The printed text matches the reason for the manifestation, and, if People remain well aligned, it reads without difficulty. He transport of this type of banner, from the place of manufacture to the place where it unfolds, it is done without difficulty bending it on itself and introducing it in the trunk of a car.

The second category of banner, carried by two or more people, is the type of those who fly. Consists on a piece of cloth, normally white, that is attached to two carrier masts used to raise the banner above They carry it and their companions. Alignment problems do of this type of banner the least convenient to read the printed text, since, as soon as the tension decreases, the fabric It ripples between the masts. The transfer from the place of manufacturing has the disadvantage of excessive length of masts The fabric, however, can be folded without difficulty.

The third type of banner consists of the banners that are carried individually. They consist of only one mast to which a thin sheet of nails is attached by nails wood or cardboard where the text of the motto or image is printed. TO Sometimes, the opposite side is also used with another sheet of peers features hidden by the mast at the rear and wide the useful surface of the banner. The readability of the text or Image vision is optimal on these types of surfaces. He transfer of this individual banner from the place of manufacture It presents the maximum inconveniences. It is not easy to find a site in a car to transport it comfortably, especially If the vehicle is going to be occupied by several people. Even the security may be compromised if the banner moves during the transfer, thereby hindering driving or visibility. The wood sheet, although very thin, cannot be folded. These circumstances are, perhaps, the reason why the banners individual, in fact, are little used in relation to the number of protesters The subsequent storage also represents a problem due to its volume, so you generally choose Use them only once. On the other hand, manufacturing with certain Quality of this type of banners by hand is not exempt of inconveniences and supposes, at least, a visit to the carpenter who will not always be willing to attend the order with urgency requested.

The technical problem raised affects the type of banner carried by two people in the only aspect of shortening the length of the masts to make the comfortable transfer possible from the place of manufacture to the place of manifestation and this is easily achieved by dividing the mast into two or more parts and joining them later by means of a sleeve.

The technical problem, in relation to the individual banner, affects the entire team and its solution It is the main reason for this application. For it, the sheets of wood or cardboard front and back where it is printed the text is replaced by a very thin band of material plastic, cloth or paper, closed on itself, that rests internally in a frame equipped with two crossbars one of the which, the lower one, skewered by the carrier mast, slides and Tense both sides of the band at the same time. The mast of this banner individual is also divided into several parts, so that the Length of each part does not exceed one hundred cm. of length. These parts, when disassembled, form a very easy set of wrap, tie and transport. The printed sheet is rolled up around all the sectioned masts and crossbars, and, thus packaged and ready for reuse, it is introduced in a bag out of the visual reach of others.

Explanation of the invention.

The structure that forms the frame of the New two-sided detachable banner is very simple. Consists of two crossbars, upper and lower, provided with a housing each; a carrier mast; a closed band on itself, one or several sleeves and one or two pins.

Both crossbars are of equal dimensions and form, differing only in that the accommodation or cavity of the upper crossbar, located in the middle of the lower face, is blind while that of the lower crossbar, also located in the half of the crossbar, is a through hole.

The crossbars, which at the time of assembly they are placed horizontally inside the band, they are kept in the same plane by means of the carrier mast.

The lower crossbar is crossed in its part mediates completely through the carrier mast, ending this by embedded in the blind recess of the lower middle part of the upper crossbar

The crossbars, both of equal dimensions, they can be of round, rectangular or square cross section, Like the masts. However, both forms can be combined, for example: round crossbars and mast rectangular, etc.

In order to keep the crossbars facing and in the same plane, the blind housing or recess of the crossbar upper and the through hole of the lower crossbar must be square or rectangular, regardless of the exterior shape of the crossbars, and identical shape must have the mast. Without However, these holes and recesses could also be round, and, in this case, to prevent the crossbars from rotating on the mast losing the plane, a pin is provided that crosses the band, the crossbar and mast.

The holes for these pins in the upper and lower crossbar and in the corresponding area of the masts, they have to be well aligned, relative to each other, to In order to keep the crossbars in the same plane.

The lower crossbar, which can slide freely along the mast, exerts downward traction from the inside of the built-in band keeping it stretched. This traction, of very low intensity, may simply be the one Provides the crossbar's own weight. Greater traction can be provided manually, from the outside, on the crossbar bottom with the built-in band and keep it by means of a pin that crosses the band, the crossbar and the mast. This form Stretching the band from the inside is very effective, obtaining a smooth two-sided banner, even with poor quality paper like newspaper. If you opt for the paper to make the band that best features Presents is the so-called slightly waterproofed couché.

The width of the band is limited by the width of the crossbars but not their height since, like the lower crossbar can slide, the height of the band can Become the one with the mast. This makes it possible to vary the shape of the band using the same frame and that can be rectangular if the lower crossbar stays close to the upper and become square or clearly vertical, as the crossbar descends. Each chosen form requires your band specific.

The thickness of the mast affects the thickness of the crossbars since it occupies a centralized position in these and, if you want to provide some strength to the crossbars, these would be quite bulky and heavy. In order to prevent this drawback, the cross section of the mast must be clearly landscape, can be its width between 10 or 15 times greater than its thickness. This wide mast shape can also be taken advantage of, the part that does not hide the band, for the impression of ornamental motifs or slogans arranged vertically preferably.

An alternative way of manufacturing both crossbars, which avoids its excessive weight consists of two slats of plywood between 0.3 and 06 cm. thick and 3 cm. from height, singing posts, between which at least 4 stands separators between 0.4 and 0.7 cm. thick, located two in the middle and the other two towards the ends. Central separators of the upper crossbar are arranged so that a free space between them that allows the introduction of the part mast center When this manufacturing system is used for the crossbars, the upper end of the mast is modified creating two shoulders that rest on the bottom of the spacers. The space between the central separators of the lower crossbar It has the same width as the mast so it can be skewered. TO despite the weight advantages of this crossbar alternative, herein, and for its extreme simplicity, the upper crossbar type is chosen with a blind recess in its lower middle part and for one shoulder end without shoulders.

The upper crossbar keeps the band as a hanger from the inside and supports the traction that is exerted from the lower crossbar when tensioning the band. The blind recess of upper crossbar has a depth of at least 1 cm. Mast and upper crossbar are held together by pressure and only if the Mast and transom housing are round a required passer through them, as well as the band, to Keep them in the same plane.

If you want to obtain the minimum volume of equipment, all its components can be hollow, of different diameter, in order to stuff them and obtain a single tubular body that facilitate transport and storage. The rolled band it can also be introduced inside this body tubular.

The band constitutes the physical medium where the text or image is printed. It is a thin sheet of plastic material, paper, cloth etc. closed on itself, provided with a small central opening through which the end of the mast is introduced at the time of assembly. Also provided with the necessary small openings that allow the placement of the pins used to maintain tension on the lower crossbar and to prevent the rotation of both crossbars when using the mast and housings of the round crossbars, as already mentioned
saying.

The band, when installed and stretched in the frame, forms a two-sided banner and must be taken in account, if the printing of the band is mechanical so that one of the Images or text is not inverted. The strong and satin paper for the band it is the best material since it does not produce practically no ripple when stretching, it is affordable and priced reasonable.

When the band is made of paper and is not closes before in the factory, it is convenient that one of the ends is previously gummed and moistened and close shortly before assembly, since, as the best means of packing the band is rolled on itself, forming a tube, if it joins before Roll it up wrinkles in its final stretch.

In order to make the union or closure, in situ , of the band at its ends more comfortable, the precise indications are printed on it by means of dotted lines, shading, colors or short texts of the type: "top", "bottom "," take off "," moisten ", etc. for the purpose of a good framing of its ends that avoids undulations when stretching the band.

The band closes overlapping its ends about 2 cm, but not facing them. This prevents the extremes from tending to take off when exerting traction, avoiding, likewise, a surplus of unesthetic material. The ends of the band, already joined, must be arranged to be placed on top of the crossbar superior in order to avoid the vision of the transverse line of Union. This position also determines the exact situation of the central hole of the band, where the end of the mast, and that of the small openings for the pins.

If the band is made of plastic material the most convenient thing is to proceed to its closing at the time of its manufacturing. Avoid bending the band firmly forming squares during transport or storage, whatever the material with which it is made.

The sleeve is a hollow body of wood, plastic, aluminum, etc. equipped with an internal separating partition or a circular flange that gives rise to two cavities each of a similar shape and size to that of the splicing bodies, in this case the masts. Outwardly it also adopts the shape of the mast. It must not exceed, in thickness, that of the crossbars so that when the sleeves are used in the part of the mast located inside the band they do not have contact with it and deform it when stretched. The ends of the masts adapt very tightly to the inside of the sleeves so that they are maintained by pressure and thus avoid the use of
pins

Embodiment of the invention

The different parts that make up the team are transported, disassembled, inside a bag, from the place of purchase or address. As none of its components exceeds 1 meter in length, the equipment can be transported in the trunk of a car. If the band is paper, and it hasn't been previously closed at origin it is closed. TO then the crossbars are introduced horizontally, in the inside the band on either side of it. He Mast end is passed through the central opening of the band and skewer the lower crossbar, being embedded, to then in the blind housing of the upper crossbar. Be slide the threaded lower crossbar along the mast to That the band is fully stretched. A slight traction, exerted downwards and applied externally on the crossbar Lower, it is enough to get two smooth surfaces. Whether you want to maintain this tension, although it is not essential, you insert a pin that passes the band, the lower crossbar and The mast. In the same way we proceed when the band is made of cloth or plastic material. If the recess and the hole of the crossbars and the mast itself are round the presence of pins and, in this case, before stretching the band proceed to place the upper crossbar pin and, already maintained, it stretch the band and place the lower crossbar pin.
