Definitions

  • Some rules are made up of one-piece elements and therefore must be the desired length. They are held between the ceiling and the floor by a screw device called a jack. Others are telescopic and adapt to a greater or lesser height of parts. The telescopic part, immobilized in its sheath, the rule is blocked between the floor and the ceiling thanks to the pressure of a pre-compressed spring.
  • the lower and upper end of these rules include ears or hooks which allow a vertical line to be stretched, which serves to support, throughout the construction process, the horizontal line guiding the laying of the bricks building blocks. These hooks or ears are arranged on two perpendicular faces of the rule. This does not allow the correct positioning of the cords for the so-called salient angles.
  • the current telescopic rules do not allow a very large part size, the operator must have access simultaneously to the extendable part to raise it, the foot located on a pedal in the lower part exerts the pressure serving to compress the spring necessary for blocking between the floor and the partition, and the other hand positioned opposite the blocking in order to achieve immobilization at the desired dimension. It is clear that the dimensions of the rules must be in agreement with the average heights of the operators who use them.
  • the document FR. 2,507,653 describes a telescopic ruler.
  • the object of the present invention is to remedy the above drawbacks.
  • the telescopic part of the rule In order to allow the operator, whatever its size, to be able to reach and act on the telescopic part of the rule, it consists, for its female part, of square tubes split in an angle, which thus allows the passage of a form of gripping integral with the male part sliding inside the female part.
  • This form of grasping is located in the lower part of the male part and is integral therewith, it is therefore easy for the operator, after having unlocked the two parts, to raise the male part by lifting this form of grasping, the operator having the foot supported on a horizontal shape integral with the female part thus compressing the spring jack located in the lower part of this same female part.
  • the operator will suffice for the operator to block the male part relative to the female part by means of the eccentric device located in the upper part of the female part.
  • This eccentric device by action on a lever, allows either to move apart or to bring the two faces located on either side of the vertical slot of the female part.
  • the gripping shape integral with the male part also serves as a limit switch in the upper part by abutting against the eccentric locking device, this ensures minimal grip inside the female part and thereby avoids even, a bending of the male element relative to the female element.
  • this rule is equipped with two rubber tips located at each end; on the male part as regards the upper part, and on the spring jack, in the lower part.
  • These tips have hollow shapes located on three vertical edges.
  • metallic pieces appear, acting as attachment ears or hooks for the cords.
  • These provisions allow, on the one hand, not to have the hooks or ears projecting from the general profile of the rule, therefore removing the fragility thereof, on the other hand, to allow effective blocking of the cords in these forms since a part is metallic, therefore rigid; the other part, that is to say, the end piece being a plastic or flexible element of the synthetic rubber type.
  • These tips also serve to protect the high and low support surfaces when using the rules in constructions already made and finished, for example during renovation, extension.
  • the telescopic rule consists of a female part 1 in which slides a male part 2.
  • This female part has a locking element 4 located at its upper part and at its lower part by a support corner 5.
  • the female part 1 is equipped with an end piece 3 at its lower part
  • the male part 2, for its part is equipped with an end piece 3 at its upper part.
  • Figure 2 shows the position of the hooks or ears receiving the cords arranged along three vertical edges of the tips 3 located at each end of this rule.
  • Figure 3 shows in longitudinal section all the main elements making up this rule.
  • the male part 2 slides in the female part 1 and comes at the end of the lower stroke to bear on a stop 8, this stop 8 being secured to the support corner 5.
  • the support corner 5, secured to the female part 1, allows the operator, by exerting a downward pressure on the foot, to compress the spring 9. This spring, by relaxing, will ensure, by pressure, the blocking of the rule between the floor and the ceiling.
  • FIG. 4 shows in section, the male part in the female part blocked by an eccentric device 4, this device serving to bring the faces 1a and 1b on the male part 2, this bringing together being possible thanks to the slot 6 produced in the angle of this female part. Still according to this view 4, we can clearly see the gripping form 7 secured to the male part 2 abutting in the upper part on the locking device 4. This arrangement ensures, as described above, a minimum fitting of the male part 2 by report the female part 1 of the rule; on the other hand, prevents the male part from inadvertently escaping from the female part during transport or handling.
  • Figure 5 shows the position of the rule for the execution of a salient angle and clearly indicates the use of hooks or ears located in the end pieces 3 at each end of this same rule.
  • FIG. 6 shows, in section, the end piece 3 highlighting the hooks or ears 10, 11, 12 emerging from the hollow shapes 13 made in this same end piece 3. These hooks or ears do not exceed the external profile of this end piece 3.
  • the position of the hooks or ears 10, 11, 12, inside the end piece 3 therefore allows a position of the vertical cord 16 always offset with respect to the layout of the partition, this offset between the horizontal cord 17 and the bulkhead bricks being necessary for the operator to properly align its construction.
  • Figure 7 shows the use of a telescopic ruler during the construction of a partition making a re-entrant angle. At this time, the user uses the hooks or ears, marks 10, 11, 12 to fix his vertical cords 16 supporting the horizontal cord 17 allowing straightness of construction.
  • Figure 8 shows well, in the section of the tip 3, the position of the cord on the hooks 11 and 12 and it is also clear, that the hooks 11 and 12 allow the cord a shift of a few millimeters from the layout theoretical of the partition, which facilitates the installation of the brick elements and their alignment.
  • FIGs 6, 8 and 9 show the principle of blocking the vertical cord 16 between the hooks 10, 11 and 12 and the tip 3.
  • This tip 3 is made of flexible materials such as synthetic rubber or the like.
  • the hooks are metallic so offer a rigid part.
  • These same hooks have an inclined face 15, the inclination of which is different from that of the pad 3.
  • These inclinations 14 - 15 go, as they approach downwards, towards the axis of the hooks 10, 11 and 12.
  • These two inclinations concurantes allow the vertical cord 16 to be properly wedged since, by pulling on the latter, it is automatically wedged between the flexible part of the end piece 3 and the rigid part of the hook 10, 11, or 12.
