Technical field of the invention

The invention relates to a marker band comprising a number of markings which are preferably equidistantly spaced apart for marking measures. 5 Background of the invention

When setting up so-called cover boarding to form a facing or cladding panel on external walls, a number of boards are first nailed in position at predetermined spaced-apart intervals, whereupon a further number 10 of boards are nailed to the boards already in position, to cover the intervals. To space out the boards of such a boarding as uniformly as possible and also to locate the boards substantially vertically in the ^' finished wall, spacing pieces are used which are applied 15 between each board as last nailed and the next board. In actual practice, however, the use of such spacing pieces as distance-determining means causes annoying problems in the form of an uneven distribution and poor vertical positioning of the boards. In fact, 20 the boards in a given lot are frequently of different width, and if the spacing piece has a width which is estimated to yield a uniform distribution of the boards from the first board at one end of a wall or a wall section, to the last board at the opposite 25 end of the wall, it frequently occurs that the last board in the wall will not be correctly positioned, a problem which must usually be solved in that the board is split or, alternatively, the 5-10 last boards of

^~ ~f the cover boarding are taken down and put up again 30 at a modified centre distance. In both cases, the finished wall will have a less attractive appearance. A different manner of locating the boards of a cover boarding is to mark the mutual distances between the boards in advance by means of a rule or measuring

tape. ^" This is, however, a most time-consuming technique which also results in poor reliability with regard to the vertical positioning of the boards. Brief description of the inventive idea The present invention aims at solving the above- mentioned problems in a simple and rational manner and to this end relates to a marker band which is primarily characterised in that it consists of or includes portions of an extensible material, preferably rubber, allowing the band to be extended, while propor¬ tionally extending the distances between the markings on the band.

Brief description of the accompanying drawing In the drawing FIG. 1 shows a marker band designed according to the invention, in its non-extended and its extended state, and FIG. 2 shows a portion of a wall to which a cover boarding is to be fastened by using the marker band according to the invention.

Detailed description of an embodiment of the invention

Fig. 1 illustrates a marker band 1 comprising a number of markings 2 which in this case are equi¬ distantly spaced apart, i.e. the distances between neighbouring markings are equal. According to the invention, the band consists of an extensible material, preferably a rubber or rubber-based material, allowing the band to be extended, while proportionally extending the distances between the markings 2, as will be obvious when the upper Figure illustrating the band in its non-extended state, is compared with the lower Figure illustrating the band in its extended state. When extending the band 1 in its entirety to for instance twice its length, the distances between each of the pairs of markings on the band will thus be doubled. According to a specific feature of the invention, the fields, e.g. the fields 3 and 3 ¹ on both sides

of a separate marking 2 have different colours. Suitably, the band may have three different colours in successive fields of this type. For example, a first field can be white, the next one red and the last one black. Fig. 2 illustrates the use of the inventive band when determining the position of boards 4 intended to be nailed to abutment studs 5 to form a cover boarding on the wall of a house. First, bands 1,1' are applied to both the upper stud 5 and the lower stud 5' , one end of each band being attached, for example by a . nail, to one end of the wall, whereupon the bands are extended to the appropriate length by pulling on the other, free end of the band. The appropriate length is determined on the one hand by the desired distance between the boards 4 and, on the other hand, by the ambition to position the last board exactly at the corner of the wall. Then, the two bands are permanently attached to the associated studs, whereupon the boards 4 can be nailed. When applying the bands, care must be taken that the two band ends which are to be attached first, are located along a vertical line, whereby the markings on the two bands are auto¬ matically located vertically relative to each other, when the two bands are extended equally. Since the fields 3 between the various markings are of different colours, it is ensured that the boards 4 are always nailed vertically as soon as one edge of the individual board is connected to markings on the same side of two fields of the same colour on the two bands. As is evident from the above, the bands which are used in accordance with Fig. 2 constitute disposable articles and will remain in the wall. This brings no disadvantage in so far as the bands can be produced at extremely low costs, and the time that is saved through the possi- bility of quickly and accurately determining the position of the boards far outweighs the cost of the bands.

Of course, the invention is not restricted merely

to the application described above. Thus, the inventive marker band can have the character of a non-disposable article and be used repeatedly for all sorts of marking jobs. Further, the band can be modified to consist of a plurality of solid or rigid members, e.g. elongate plates, and a corresponding number of bands of extensible material between these rigid members, said connecting bands providing the proportional extension of the distances between markings which may consist of the solid members themselves or special symbols thereon.
