Definitions
- the invention relates to an injection molded plastic part, comprising a substantially flat part, oriented along a given reference plane, an inner face of which is provided with at least one fastening means, the fastening means consisting of a bridge having a median plane, adapted to support a clip and having two side walls, opposite to the median plane and interconnected by a staple support wall.
- Such aspect pieces are found in the more particular field of motor vehicle door side rods.
- the staple holder 10 of the state of the art comprises side walls 12 connected to an inner face 14 of a rod 16 via a thinned cloth 18. Removal of the material blocked in this zone by the wedge of the mold (not shown) generates a deformation of the part at the time of demolding. There may also be a shrinkage if the ratio between the thickness of the wand and the thickness of the staple holder is not optimized. It thus appears difficult to use such a staple holder, because of the limited possibility of holding the wedge in position during molding and due to appearance defects.
- the object of the invention is an aspect part comprising at least one fastening means whose design, simple and inexpensive, makes it possible to avoid appearance defects.
- the invention proposes an appearance piece of the type mentioned above, characterized in that the lateral walls of the bridge comprise, on their external faces, ribs whose one end extends projecting with respect to a plane defined by an edge of the sidewalls opposite the staple support wall and is connected to the inner face of the appearance piece so that a space is provided between the plane defined by the edge of the sidewalls and the face. internal aspect of the room.
- the ribs are oriented in transverse planes substantially perpendicular to the median plane and the reference plane.
- the side walls are interconnected by an end wall, a space being provided between an edge of the end wall and the inner face of the piece.
- the ribs are thinned at their connection area to the inner face of the part of aspect, an inner part desd ⁇ tes ribs having a recess.
- the side walls of the bridge are extended by an additional rib oriented substantially parallel to the median plane.
- the additional rib is arranged near the end wall.
- the plane R defined by the edges of the side walls form an angle with the reference plane of the part, so as to facilitate demolding.
- FIG. 1 is a perspective view of a part with a fixing means according to the state of the art.
- FIG. 2 is a perspective view of a part comprising a fastening means according to the invention
- FIG. 3 is a side view of the part of FIG. 2.
- - Figure 4 is a sectional view of the part of Figure 3, in Ia direction IV-IV.
- FIG. 5 is a sectional view of the part of FIG. 3 along the direction V-V.
- an injected plastic part 20 has a substantially flat surface.
- the surface of the part can also be curved, but for practical reasons, we will take as a reference a plane S.
- the appearance part 20 may be for example a side strip intended to equip a motor vehicle door.
- the part of appearance 20 comprises, on its inner face 22 a fastening means 24 which is constituted by a bridge 26 of median plane P, for carrying a fastening clip (not shown).
- the bridge 26 has two side walls 28 opposite to the median plane P.
- the side walls 28 are interconnected by an end wall 30, oriented substantially parallel to a transverse plane T, said transverse plane T being perpendicular to the median plane P and to the reference plane S.
- the bridge 26 has a U-shaped profile: a wall 32, substantially parallel to the reference plane S of the part 20, interconnects the side walls 28 and the wall of FIG. end 30, the wall 32 has an opening 34 for receiving the clip.
- the side walls 28 have on their outer face 36, a plurality of ribs 38, parallel to each other and oriented in a transverse plane parallel to the plane T.
- the ribs 38 each have an end 40, in protruding from an edge 42 of the side walls 28, said edge 42 being opposite to the staple support wall 32, the edges 42 of the side walls 28 define a plane R substantially perpendicular to the middle plane P "
- the plane R may not be perpendicular to the median plane P
- the fastening means 24 may not have symmetry with respect to the median plane P.
- the ends 40 of the ribs 38 are connected to the inner face 22 of the part 20, so that a space 44 is formed between the edge 42 and the inner face 22 of the part 20.
- the ribs 38 have a profile forming part of a triangle, one side of which is connected to the internal face 22 of the part 20.
- the ribs 38 are thinned at their region of connection to the inner face 22 of the part 20: and an inner portion 46 of the ribs 38 has a recess 48, so as to facilitate demolding.
- the bridge 28 is thus connected to the inner face 22 of the part 20 only by substantially point-shaped connection zones, formed by the ends 42 of the ribs 38,
- the molding of the part requires a mold (not shown) comprising a sliding wedge (not shown) intended to be inserted inside the bridge 26,
- the plane R formed by the edges 42 of the side walls 28 forms an angle ⁇ with the reference plane S of the part 20,
- the ribs 38 are formed as a punch by the mold cavity and not by the wedge, which has several advantages; the span of the wedge in the housing formed in the bridge 26 is increased, which makes it possible to limit the deformations related to the injection pressures,
- the ribs 38 keep the piece 20 in the mold while the shim is removed.
- the appearance part 20 according to the invention therefore has fewer appearance defects such as corrugations or sinkholes, for example, maize also such as traces of flux that may appear behind the wedge.
