Definitions

• Half-shells that can be clipped together, especially for hole edging are half-shells that can be clipped together, especially for hole edging:
• the invention relates to two half-shells that can be clipped together congruently and supplemented to form an eyelet, in particular for edging a textile or the like, the two half-shells forming an eyelet eye engaging with one another on both sides and one of the two half-shells forming a plurality of mandrels in the region of their parting plane , the tips of which dip into a circular ring channel in the other half-shell.
• An eyelet of this type is known from DE-GM 298 00419.
• the spikes that penetrate the textile be it in the form of vehicle tarpaulins, shower curtains, window curtains etc., have a tear-free, captivating edge on the eyelet.
• the eyelet has a circular floor plan, the one half-shell equipped with thorns being held in a rotationally fixed manner with respect to the textile; the other half-shell, which presents the ring channel, is not rotationally fixed in this regard, although it experiences a certain amount of rotationally braking friction through the mutual locking engagement of the half-shells.
• the invention proposes that a finding gap is formed radially on the inside of one half-shell, which can also be assigned a finding projection of the other half-shell projecting radially on the inside beyond the parting plane of the shell halves.
• the finding upstream of the clipping results in the operational assembly of the eyelet.
• the snapping of the joining partners can even be felt.
• the operator can roughly follow the outline of both half-shells.
• the tongue mandrel then snaps into the associated plug-in cavity practically blind.
• the finding gap is a recess in the radially inner snap collar of the one half-shell.
• the finding gap can also be taken into account in terms of shape.
• a reversible locking engagement connection is used, so that the perforated border can be loosened again, for example if the half-shells are not to be subjected to a washing process and the mechanical or abrasive loads associated therewith.
• the eyelet can be like open an oyster. This is achieved or favored by an opening of the radially outer edge of one of the two half-shells, which is in particular opposite the tongue and open towards the parting plane.
• the tongue of the tongue, the finding gap and the opening lie on an alignment line which intersects the center of the eye of the eye, the free space enclosed by the half-shells lying between the mandrel on the one hand and the finding gap and opening on the other.
• the opening can even function as a viewing window, with an insight into the finding aids and their surroundings.
• the two clipped half shells form a hollow plastic body. This has a material and weight saving advantage. There is also a certain supple elasticity. It is also provided that the end of the tongue lies on a circular arc line, in the center of which the mandrel is located. This creates a sufficiently stable environment.

• the half-shells 4, 5 consist of plastic material. This is of a certain elasticity. It is preferred to use translucent or transparent plastic material. Because of the shape of the shell and the opposing arrangement of the half-shell cavities, the joined half-shells 4, 5 form a hollow plastic body.
• the two half-shells 4, 5 lying on both sides of the textile 1 between them are connected to one another in the manner of a push button, one half-shell 4 being fed from one side and the other half-shell 5 from the other side of the textile fabric.

• the snap collars 7, 8 overlap and engage behind one another in a clip direction lying transversely to a parting plane E-E of the eyelet ⁇ , the clamping plane of the textile 1 (for example, reference is made to FIG. 6).
• the free ends of the radially inner snap collars 7, 8 each form a snap bead 9 or 10. They are rotationally symmetrical.
• the snap collar designated 7 ends at the level of the parting plane EE, namely in front of an annular shoulder 11 of the other half shell 5.
• the annular shoulder 11 essentially corresponds to the width of the snap collar 7 including its snap bead 9.
• the hole contour of the eyelet 6 is so with respect to both half shells 4 , 5 continuously.
• the snap collar 8 clearly protrudes over the annular joint 13 or the parting plane EE.
• the one half-shell 4 in collar does not exceed the level mentioned.
• the parting plane EE runs essentially at half the height or thickness of the hole surround 3 or eyelet ⁇ .
• the selected shell shape of the half-shells 4, 5 gives the hole surround 4 a cavity 14.
• this also accommodates a restraining device 15 holding it.
• the textile 1 is anchored in the area of the perforated edge area 16 in a claw-ring-like manner so as to be pull-out resistant.
• a component of said restraining device 15 is a mandrel 17 as the male part assigned to the half-shell 4 and an annular channel 18 realized in the other half-shell 5, specifically as a female part.
• the top of the cathedral is designated 19. It forms a cone-shaped lancing section of the dome 17. The length is such that it clearly exceeds the clamping plane or parting plane E-E in the direction of assignment.
• the tip 19 pierces a hole 20 in the hole edge region 16. This is done extremely gently, and more so by displacing the structure of the textile or sheet-like fabric.
• the necessary, anvil-like counterpart is provided by relatively closely adjacent end faces of two concentric ring walls 21, 22 which delimit the ring channel 18. The end ends extend to the parting plane E-E.
• the inner profile of the ring channel 18 is profiled in the manner of the silhouette of the tip 19 of the dome 17 in a notch-shaped manner, leaving a gap dimension, so that the free-standing tip 19 is protected for repeated uses, that is to say the repeated assignment of the hole surround 3.
• the mandrel 17 is conspicuously conical in the actual lancing area. Its base facing the inner wall 12 of the half-shell 4 merges into a relatively shorter cylindrical base. It is rooted in the inner wall of the half-shell 4.

They lie on a circular line corresponding to the circular ring channel 18, in which ring channel 18 the mandrels 17 are immersed in a defined manner. Any radially oriented tensile forces on the textile 1 would only bring about the longitudinal application of the tapered dome 17 on the corresponding annular channel flank, which would remain recognizable without damage.
• a mandrel 24 is formed in the region of the end of the tongue 23 of the one half-shell 4.
• This externally standing mandrel 24 is physically formed like the mandrel 17, that is to say has a pointed cone 25.

• the finding gap 28 clearly shows the notch that is adapted to the shape.
• the locating projection 29 extends slightly from the snap collar 8 at a distance from the annular shoulder 11 of the other half-shell 5.
• the finding aid designed in this way can be felt with regard to the effect that occurs; it has a practically self-regulating effect.
• the levels for the thorn entry and the immersion of the finding before jump 29 can be laid out in such a way that priority is given to the latter function.
• the eyelet ⁇ can be opened, for example when carrying out a washing measure, simply by inserting a blade into the annular joint 13 with a slight tilting movement of the said blade.
