Definitions

  • the invention relates to the field of tracing instruments such as rulers, squares, or protractors. These instruments allow you to trace or cut certain materials on a support.
  • the tracing instrument previously proposed includes a ruler locking handle making it possible to stabilize the ruler in use. More precisely, the proposed instrument included fingers/feet to be housed in holes for sliding, and a non-slip locking means B larger than the holes, to be fixed under the fingers/feet with reference to the figure 1 .
  • the variants with a longitudinal blocking foot were not satisfactory in terms of support on the blocking structures throughout the rule.
  • the PB blocking foot was rigid, allowing only one stop of the handle on the tracing support and this caused play on the instrument supposed to be blocked in the blocking position, which resulted in pitching problems around it. an axis in a plane parallel to a main axis of the rule so that maintaining the blocked rule thus became unstable, which hampered its use because it distorted the layout.
  • the basic principle is to design parts with constant thicknesses, this makes it possible to guarantee object manufacturing without defects, in particular deformation linked to flatness or straightness, essential criteria for the manufacture of a ruler for example.
  • a short length tracing structure can be injected at the same time with the handle receptacle in one piece with a single mold since the thicknesses are almost identical.
  • the thickness of the tracing structure increases as a function of its length, and consequently the production in a single piece is more complex because the thickness of the walls of the handle receptacle is too thin compared to the thickness of the tracing structure. The more the length of the rule increases, the more difficult or even impossible it is to achieve.
  • an objective of the invention is to remedy the defects of the prior art, and in particular to propose a tracing instrument that is simpler to produce and quicker to assemble, and preferably significantly limits the problems of bracing and jamming, having good hold in blocking.
  • the invention also focuses on a method comprising a method of assembling an anti-slip device to be assembled/mounted on a tracing structure of different types such as for example wood, plastic or metal.
  • the materials machining technique makes it possible to manufacture quality tracing structures, without being constrained by thickness or length.
  • the handle receptacle is assembled to the tracing structure so as to form an assembly.
  • the invention proposes an assembly of an anti-slip device with a tracing structure making it possible to limit the problems of the prior art.
  • the handle is reducible in height along the Z axis perpendicular to the tracing support in use.
  • the tracing instrument is configured so that the handle abuts with the handle receptacle and the tracing support in the locking position.
  • the handle abuts at least on an upper edge of the handle receptacle, in order to press the tracing structure onto the tracing support in the locking position.
  • Specific stops are provided for this purpose, illustrated in the Figure 3 . This allows the tracing structure to be properly maintained in the locked position, avoids the play of the prior art, and ensures overall stability of the tracing instrument in use.
  • the handle receptacle and the tracing structure each include first and second leg bores receiving the locking feet and the sliding locking structures, such that the locking legs and the locking structures can slide in the corresponding bore.
  • the handle receptacle comprises at least two foot bores, and at least two return structures, and the foot bores are separated from, and alternate with the return structures along said longitudinal axis.
  • the handle receptacle and/or the tracing structure each comprise foot bores receiving the locking feet and the sliding locking structures, and the blocking feet and/or the blocking structures act as a slide structure.
  • the blocking feet and the foot bores are in the shape of a quadrilateral.
  • the blocking feet also act as slide structures.
  • the handle comprises at least one slide structure and the handle receptacle comprises at least one internal guide slide structure receiving and cooperating with the slide structure of the handle upon insertion of the handle. This allows the handle to be inserted without offset during assembly.
  • the handle receptacle is assembled and attached to the tracing structure.
  • the handle receptacle may be removably attached to the tracing structure.
  • the tracing instrument may comprise at least two different tracing structures which can be fixed alternatively on the same handle receptacle. This allows tracing kits to be made with a single standard [handle/handle receptacle] set.
  • the blocking structures each comprise a pad receptacle equipped with a pad, preferably elastic with a half-spherical rounded structure, the thickness of the pad is greater than minimum sufficient for the pad to be crushed.
  • the blocking feet are in one piece with the blocking structure, the handle body, and preferably the pad.
  • a one-piece skate with the locking structure can be made from a two-material composite, for example plastic.
  • the shoe receptacle is movable relative to the blocking foot, in particular in translation upwards or downwards, with a downward return means; and/or in rotation around a skate axis in a plane parallel to the tracing structure.
  • the mobility of the pad receptacle and the elasticity of the pad allow the handle to abut with the handle receptacle and thus to compensate for any vertical play on some of the feet for better blocking.
  • the rotation of the skate receptacle allows the contact surface of the skate to tilt when pressure is exerted on one side of the handle, thus the contact surface of the skate with the support is increased/maximized.
  • the tracing instrument comprises snap-fit structures around the locking feet and grooves in the handle receptacle and/or the tracing structure so as to create a locking by clipping of the corresponding structure of the handle .
  • This allows the handle to be quickly attached to the handle receptacle.
  • tab-lock structures allow slide structures to be centered in the bore to eliminate friction.
  • the handle and the handle receptacle have fixing means cooperating together.
  • the handle receptacle comprises gripping means, preferably one or two tabs. This makes it easier to handle the tracing instrument.
  • the handle body has a dome shape to transfer force to the sides when pressure is exerted on the center of said body, and at least two pads make contact with the tracing support when pressure is exerted on half on the left or on the right half or in the center of the handle. This ensures stability of the tracing instrument on several pressure zones of the handle.
