WO2005066583A1 - Level providing degrees and percentages - Google Patents

Abstract

The invention relates to a level that provides degrees and percentages. The inventive level is characterised in that it comprises a body in the form of a section preferably having a double-T-shaped cross-section of variable length and with ends that are inclined at 45 °. The core of the section is provided with a central octagonal bore and two lateral grooves, and an inner octagonal part is fitted tightly therein, said part comprising two lateral flanges and a central circular recess. Moreover, the ends of the part are sealed with two pieces of glass which, in turn, enclose a liquid inside the level. The diameters and measurements necessary for calculating degrees and percentages are represented on the two pieces of glass which are divided into four parts.

Description

 Level of degrees and percentage.

Technical sector Generally, a level, as indicated by its own word, is used to measure the horizontality and verticality of a surface and usually the bubble is in a horizontal housing. State of the art Up to now the level has had limitations that have caused certain problems in its use, for example measuring the flat or not that a surface that forms a certain angle with the horizontal may be. That is, checking an inclined surface. To avoid these problems, the level of the invention has been devised, which allows full use to measure the angle of inclination of the surface on which the level is arranged. It would therefore be desirable to obtain a level that placed on an inclined plane allows us to measure the percentage of the inclination and the degrees of said inclination. DETAILED DESCRIPTION OF THE INVENTION The level is constituted by a profile, which can be made of aluminum or some type of plastic to provide lightness. In the center of the soul of the profile, an octagonal shaped recess and two lateral recesses are arranged, arranged one on each side of the profile, to fit the basic part of the level tightly in them. The level due to its height is cut at its ends with an inclination of 45 ° degrees, which allows us to check a square. Within the core of the profile with the recess and the two lateral recesses mentioned above, the level itself is adjusted as follows; - With an octagonal shape, two transparent crystals leave a circular cavity inside.

SUBSTITUTE SHEET (RULE 26) - This cavity contains a liquid inside the circle. - The liquid must be sufficient to cover half the circle in a horizontal plane. - The two glass covers are screen printed and divided into four parts, two for degrees and two for both percent and these divided with the different graduations for reading. - The graduations are the same on both sides to be able to use them interchangeably. This configuration allows us and the system of subjection to the profile, allows us to change the practical base of the level for any change in the measurement by simply attaching another base with different serigraphy. Within the scope of the invention it should be noted that the profile and the level itself may have another form or constitution as long as the fundamental principle is not altered. In order to understand more easily not only the constitution but also the proper use of the level of the presentation, then a practical example of implementation is referred to, said execution being merely enunciative and in no case limiting it, all of this as and As shown in the attached drawings. Figure 1 shows a perspective view of the level of the invention. Figure 2 shows a sectional view along line 11-11 of Figure 1. Figure 3 shows the practical basis of the level in a flat view. Level 1 is constituted by a support body 2 defined by a metal or plastic profile with a double "T" section in the core of profile 3 and in its center there is a cut 4 made in an octagonal shape and two lateral recesses in a way opposite to each of the sides, on which the practical base of level 5 is fitted tightly (fig. 3). The practical base of the level is coupled to the profile, with a small turn and pressing until its coupling 6. The practical base of the level (fig. 3) is composed of two octagonal crystals 7 and to the supports 8, within the octagonal part two circles are delimited, one outside with numberings and radial marks 9 and another inside with

SUBSTITUTE SHEET (RULE 26) radial marks 10 between them is a transparent area 11 to facilitate reading on the circumference. The circumference 12 with its inner housing for liquids in which only 50% of it is covered. The two inner and outer screenprinted circumferences 13 and 9 are divided into four parts, zone of degrees 14 and zone of 15 percent with alternative calculations and measurements. The wings of the profile 16 serve as a support surface for the level seat in use. Preferably the ends of the profile 17 are inclined with a 45 degree section for square checking. Describing sufficiently the nature of the invention, as well as the manner in which it is carried out in practice, it should be noted that the provisions indicated above and represented in the attached drawings are subject to modifications in detail as long as they do not alter the fundamental principle.
