Definitions
- the present invention relates to a system for transverse attachment of a pipe to a shell.
- a system for transverse attachment of a pipe to a shell can for example be applied to the attachment of a seat base metal tubing to the rear of a plastic shell forming the seat and the back of this seat.
- US Pat. No. 4,892,355 describes, for example, a mechanism for attaching the front part of the seat to a tubular metal crossbar integral with the base, according to which said crossmember is wedged in parallel ribs having a rounded recess. following the outer shape of the tube, fixing clips then being wedged in the particular profile of the inner surface of the seat to finish securing the cross.
- the pressurizing mechanism is based on an elastic tab of the fastening clip which, compressed against the particular profile of the shell, allows the exercise on the tubulure of a force oriented in a direction substantially perpendicular to the force restoring the energy stored during compression of the elastic tab.
- the system of the invention allowing the transverse attachment of a tubing to a shell, comprises:
- a housing in the hull ensuring the positioning of the tubing for attachment to the hull;
- a locking clip blocking the tubing in its previous position; and it is characterized in principal that the housing and the clip are provided with locking means from one to the other and positioning means of one relative to the other in the direction of the axis of the tubing.
- the fastening means which allow locking, are in this case distributed in the housing and in the clip.
- a guide in the form of the aforementioned positioning means, is further integrated in the mechanical connection.
- the housing consists of a recess at the open axial ends, made in a projection protruding from the shell, said recess having a volume partially matching the tubing, the clip covering the remaining volume.
- the lateral walls of the housing are provided, at their free end, with extensions whose external faces have protrusions intended to cooperate with corresponding reliefs arranged in the clip, said extensions and said reliefs being elastically deformed as the approaching clip / housing for fixing and until elastic relaxation when the abutment of the clip on the protuberance.
- Walls respectively belonging to the protuberances and reliefs, oriented substantially perpendicular to the direction of the binding, are then found face to face, preventing the disassembly of the clip.
- the walls of the protrusion protruding from said extensions and the relief of the clip whose cooperation allows said deformation are inclined at a similar angle and opposite sign relative to the direction of the attachment.
- the means for axial positioning of the clip relative to the protuberance consist according to the invention in axially-oriented ribs, disposed on either side of end openings and delimiting, in the direction of the axis of the tubing, a distance substantially equal to the axial length of the extensions protruding housing.
- the extensions are housed, at fixing, between said ribs.
- the attachment of the clip can therefore be performed completely, in two directions respectively transverse (clipping) and axial.
- the clip then extends the protuberance protruding from the shell outwards, and the tubing is completely surrounded.
- the recess is of cylindrical shape, and the openings at the axial ends respectively of the recess and the clip are complementary portions of the circle.
- said protuberance is integral with the shell, molded with the latter.
- the realization of such protuberances, known per se, is done for example by means of gaseous veins for injecting gas into the shell and avoiding visible shrinkage on the outer facade of said shell.
- the invention applies for example to the attachment of a metal tubing seat base at the back of a backrest or a seat formed of a shell.
- FIG. 1 is a sectional view of a shell forming a seat and back of a seat provided at the joint between these two parts, a protuberance with a housing for a tubing belonging to the base;
- - Figure 2 is an enlargement of the protuberance with its housing;
- FIG. 3 is a perspective view of the outside of a clip
- FIG. 4 is a perspective view of the inside of the same clip
- FIG. 5 is a cross sectional view of the clip of Figures 3 and 4.
- the shell (1) of the seat comprises a backrest (2) and a seat (3).
- the outer face (4) of the shell (1) is provided with at least one protuberance (5) provided with a housing (6), a detail of which is shown in Figure 2.
- the outer face (4) of the shell (1) is provided with two protuberances (5) arranged at the ends side of the hull
- the housing (6) is cylindrical, and intended to fit a tubing (not shown) which is positioned transversely relative to the shell (1).
- the outer edges of the housing (6) consist of extensions (7, T) themselves with external growths (8, 8 ').
- the shell being molded of plastic, the dimensions of the extensions (7, T) are such that they can undergo elastic flexion when the protuberances (8, 8 ') are compressed inwards, for example by cooperation with a corresponding surface.
- Such a clip (10) is shown in Figures 3 and 4. It covers the portion of tubing inserted in the housing (6).
- the inside of the clip (10), appearing in FIG. 4 shows the existence of two reliefs (11, 11 ') which allow clipping of the clip (10) on the extensions (7, T) protruding from the housing (6). .
- ribs (13, 14, 13', 14 ') permitting axial positioning of the clip (10).
- the axial ends of said extensions (7, 7 ') slidably fit between the ribs (13, 13', 14, 14 '), and the clip (10) is guided such that it naturally extends the protrusion (5) surrounding the tubing.
- the reliefs (11, 11 ') have an inclined plane (15, 15') which resolves into a surface (16, 16 ') with a shape perpendicular to the inner wall of the clip (10). .
- the orientation of the surfaces (15, 15 ', 16, 16') corresponds, in absolute value and with respect to the direction F of the attachment, to the orientation of the surfaces (17, 17 ', 18, 18') appearing in Figure 6 and which delimit the growths (8, 8 ').
- Figure 6 shows the clip (10) in the closing phase, approaching in the direction of the arrow F of the protrusion (5) protruding from the shell (4).
- the ribs (13, 13 ', 14, 14') manage the axial centering of the clip (10) relative to the protuberance (5).
- the reliefs (11, 11 ') allow, by cooperating with the extensions (7 1 ) and their reliefs (8, 8') the locking of the clip (10) on said protuberance (5). It is of course necessary to place the metal tube (not shown) before locking the clip (10) on the protuberance (5).
