The invention concerns fastening means of the type referred to in the field as clips. Such clips are used in holes of different types in a wide variety of construction elements. Clips are very common in the motor vehicle industry and are used, for example, to secure panels, but also various types of functional elements, for example cables, pipe conduits of various kinds, etc.
Clips also occur in various types of safety arrangements, for example for supporting vital parts in safety arrangements which deploy automatically in the event of collision, for example in airbags.
Clips of the type in question are input goods. Such goods have to be competitive in terms of price and satisfy stringent requirements in terms of uniform quality, and they must also meet stringent demands in respect of strength, stability and handling.
Clips made in one piece from plastic material or the like are very common. The material of the clip is chosen so that, in addition to the required mechanical stability/strength, the material also permits a certain degree of elastic resilience in areas of the clip where a kind of hinge or bridge is formed between material parts. A number of different types of clips made in one piece are already known in which heel-like elements interact with the stem of the clip via a hinge formed as a torsion hinge. These heels can be pivoted with elastic resilience into a recess in the clip stem. On assembly, the stem of the clip is quite simply pressed into a corresponding hole, the heels automatically swivel in and thereafter return to their original position, bearing against the underside of the object in which the hole is made.
Clips of said type are usually injection-moulded in multi-compartment tools or cast in a mould. The plastic material is preferably a thermoplastic, for example various types of acetal plastics, polypropylene, polyamide and the like are used. It is also possible to use thermosetting plastic.
The object of the invention is to further improve clips of said type by providing the possibility of optimum dismantling of the clip. This optimum dismantling entails that clips can be dismantled without any weakening whatsoever and can then be reinserted again into the same hole or some other corresponding hole.
For maintenance work and replacement of parts, for example in vehicles, clips are made available which permit non-destructive dismantling.
The novel clip construction makes it possible, as before, to produce the novel clip construction in the form of a clip made integral with a functional construction element. In accordance with an aspect of the present invention, a dismountable clip is provided. The clip includes a stem part, an entry end, and a hole edge attachment end, intended for insertion into a hole. The stem part has protruding heel-like elements which can be pivoted in and back out elastically. In a recess in the stem part, each heel-like element has a maneuvering shoulder at a distance inwards from a hinge connecting the heel-like element and the stem part. An axial hole for receiving a dismounting tool is formed through the hole edge attachment end and the stem part to the maneuvering shoulders. A free space is situated between the maneuvering shoulder and the entry end to allow the maneuvering shoulder and, hence, the heel-like element to be pivoted with the dismounting tool about the hinge in the direction towards the entry end.
In accordance with another aspect of the present invention, a method of producing a dismountable clip is provided. In accordance with the method, the clip is made in a divided mould tool, and the dividing plane of the mould tool is chosen such that it lies centrally in opposite sides of the stem part lacking heel-like elements. In addition, the axial hole extending to the maneuvering shoulder and the recess in the stem part are formed using the divided mould tool, using core pulling.
In accordance with a further aspect of the present invention, a method of dismounting a dismountable clip is provided. In accordance with the method, a rod-shaped dismounting tool is introduced into the axial hole in the stem part as far as the maneuvering shoulder. The end of the tool is engaged with the shoulder. The shoulder is pivoted towards the entry end, about the hinge, down into the free space between the maneuvering shoulder and the entry end. A gripable part of the hole edge attachment end or the stem part is thereafter gripped manually or with a tool, and the clip is removed without any interference from the heel-like elements.
FIG. 1 is a central longitudinal cross section showing a clip in an embodiment of the invention,
FIG. 2 shows the clip from FIG. 1, looking towards the broad side of its stem part,
FIG. 3 shows the clip from FIG. 1, looking towards the narrow side of its stem part,
FIG. 4 shows a section along the line 44 in FIG. 2,
FIG. 5 shows a section along the line 5—5 in FIG. 3,
FIGS. 6 to 8 show the principle by which the clip in the embodiment shown is fitted, and
FIGS. 9 to 12 show how the clip is dismounted.
FIG. 1 shows an embodiment of a clip 10 according to the invention in longitudinal section in a plane containing its centre axis. In the embodiment shown, the stem part 11 of the clip has a substantially rectangular cross section with opposite pairs of substantially identical broad and narrow sides (see FIGS. 2 and 3). The longitudinal section through the narrow sides is shown in FIG. 1.
The clip 10 in FIG. 1 comprises, in addition to said stem part 11 of axial length l1, a hole edge attachment end 12 which in the embodiment can be said in principle to have an axial length l2, and an entry end 13 with axial length l3.
A pair of elements 14, 15 intended for gripping the edge portion in a hole and for retaining the clip in the hole, and hereinafter referred to as heel-shaped elements, project from the narrow sides of the stem part 11. The heel-like elements lie in a diametrally continuous recess 18 which extends between the narrow sides of the stem part. In the embodiment shown, each of the heel-shaped elements 14, 15 is integral with the broad sides of the stem part via a pair of hinges, of the torsion hinge type, forming bridges 16 and 17.
On each heel-shaped element 14, 15 there is a manoeuvring shoulder 19, 20 and between these shoulders a gap 21 is left substantially centrally on both sides of the centre axis of the stem part 11.
Said transverse recess 18 in the stem part is designed in such a way that, below the two heel-like elements 14, 15, a free space 22 is formed between the underside of the manoeuvring shoulders 19, 20 and the entry end 13. This free space is dimensioned so that the heel-like elements 14, 15 can pivot about the hinges 16, 17 into the recess 18 until they lie substantially radially inside the outer surface of the narrow sides of the stem part 11.
In the clip 10 there is an axial hole 23 extending through the hole edge attachment end 12 and the stem part 11 to the recess 18. The hole 23 thus communicates with the manoeuvring shoulders 19, 20.
In the embodiment of the heel-like elements 14, 15 shown in FIG. 1, these have a substantially plane bearing surface 14 a, 14 b intended to engage against an edge portion of the underside of a hole in which the clip is intended to be inserted. To reduce the required clearance for pivoting the heel-like elements 14, 15 about the hinges 16, 17, the bearing surfaces 14 a, 14 b preferably form an angle of slightly greater than 90� to the centre axis of the stem part.
The arrangement comprising axial hole 23, manoeuvring shoulders 19, 20, hinges 16, 17 and free space 22 represents the basic requirement for obtaining effective insertion of the clip in a hole and non-destructive dismounting of the clip, for example for reusing it with the same mechanical properties retained.
In addition to the axial hole 23 representing an important element for the non-destructive dismounting (which will be discussed later in connection with FIGS. 9 to 12), it also contributes to the comparatively simple production of the clip in its entirety.
The entire structure—hole edge attachment end 12, stem part 11, heel-like elements 14, 15, hinges 16, 17 and entry end 13—can be produced in a divided mould tool with the dividing plane extending axially centrally through the narrow sides of the clip, with use of simple core pulling. It can be sufficient to pull the cores axially out from the hole edge attachment end 12 and at right angles to the narrow sides of the stem part and the entry end in the embodiment shown. An entry end 13 particularly well suited to the purpose can be made solid, and material-saving recesses can be made in the rest of the entry end and the stem part, using said simple core pulling.
Clips of the type in question, including clips in the embodiment shown, are suitably produced from injection-mouldable or castable material, especially acetal plastics, polypropylene, polyamide and the like, which, in addition to giving the desired mechanical strength, also have material properties which, as regards the hinges 16, 17, give elastic resilience, of the self-closing hinge type, and can thus form hinges operating according to the torsion principle.
FIG. 1 shows a hole edge attachment end 12 of a simple type. It has a circular sleeve-like collar 12 a and a further collar 12 b constituting the extreme end of the clip. By means of the shape that it has been given, the sleeve collar 12 a has a certain return elasticity in the axial longitudinal direction of the clip. Between the bearing surfaces 14 a, 14 b of the heel-like elements and the sleeve collar 12 a there is therefore an insert dimension with a certain tolerance, i.e. a clip with certain nominal dimension of the distance between the sleeve collar and the bearing surfaces can be used also for holes which deviate slightly from the nominal dimension. The term bearing, as it is used in the present context, does not of course need to mean that the stem part of the clip is completely fixed positionally in a hole, although such can be the case. A certain play or degree of freedom is possible if so required or if desirable.
The clip construction according to FIG. 1 is shown in greater detail in FIGS. 2 to 5. This shows, for example, recesses 24 in the entry end and the end of the stem part which save on material and which can be produced by said core pulling. The broken lines 25 indicate that the clip can be made integral with an element which has a specific function, for example a securing band for cabling or the like.
FIGS. 6 to 8 illustrate the procedure for fitting the described clip. The clip is inserted in the direction of the arrow 28 into a hole 27 in a construction element, for example a wall panel or other structural element of a motor vehicle or other object. Said nominal axial dimension between the sleeve collar 12 a and the bearing surfaces 14 a, 15 a corresponds in principle to the thickness of the construction element 26, i.e. the axial length of the hole 27.
FIG. 7 shows the heel-like elements 14 a, 15 a pivoted into the radial recess 18 in the stem part 11, obtained through bearing against the boundary wall of the hole 27. This insertion of the clip into the hole is done, for example, manually or by machine.
In FIG. 8, the clip is in its final mounted position. In the example shown, the actual bearing is against the underside of the holed construction element 29, and the sleeve collar 12 a also bears for its part against the top of the construction element.
FIGS. 9 to 12 show the non-destructive dismounting principle.
A tool 30 with a rod-shaped operative part 31 is introduced into the hole 23 in the direction of the arrow 32, either manually or by machine. In FIG. 10, the tool is at its bottom position. By bearing against the manoeuvring shoulders 19, 20, the element 31 has pivoted the heel-like elements 14, 15 into the recess 18 so that the heel-like elements lie inside or substantially in the plane of the outer narrow sides of the stem part 11.
With the tool 30 in said position, a force is then applied in the direction of the arrow 33 (FIG. 11), manually or by machine, and the clip is pressed out of the hole 27 without destruction (FIG. 12).
In the embodiment of the clip shown, the clip stem has a substantially rectangular cross section. Other designs, for example circular or polygonal, are of course possible.
It is also possible to vary the number of so-called heel-like elements connected in an elastically pivotable manner to the stem part. In the embodiment shown, there are two such elements. In an embodiment with a stem part of circular cross section, there can for example be three or more “heel-like” elements.
It will thus be appreciated that the embodiment described and shown in the drawings constitutes just one example. Variations in design and dimensions and innumerable variants including clips integrated in different types of constructions are possible within the scope of the invention.
The invention is limited only by what is set out in the attached patent claims.
