Description

A method for manufacturing a fixing base
This invention relates to bases for fixing a part .
Such bases are commonly used in the building field and mainly electricians use them, for fixing items such as wires, cables, chutes, tubes and other finishing parts to walls.
The variety of such bases is guite extended but, presently, and more commonly, they are fixed by means of a fastening apparatus for avoiding to have to preliminarily drill a hole in the wall, fixing occurring through anchoring a nail by means of the apparatus, thus referred to as a nailer.
Such an apparatus, either operating with powder cartridges or a fuel cell, is an apparatus provided, more particularly, with two safety devices, one ensured by a nail driving piston ensuring a so- called indirect shot and, the other, ensured by a pin guide at the front end of the apparatus, that should be abutted against the wall for allowing a shot to be carried out and providing the so-called abutment safety .
If the range of part fixing accessories is significantly varied, such accessories all share a common characteristic, for being fixed to a wall, of being able to be fitted onto the pin guide of the fastening apparatuses.
Thus, any part fixing base of the present application comprises
- means for receiving a pin, a plug, a nail, for fixing the base to a wall,
- means for supporting the part and - means for maintaining the part on the supporting means .
Under these conditions, the applicant had the idea to suggest that all such part fixing bases should be formed around a common or elementary component, which could be referred to as universal.
The present application thus relates to a method for manufacturing a fixing base for a part to be fixed, comprising means for receiving a fixing element for fixing the base, supporting means for the part to be fixed and holding means to hold a part to be fixed on the supporting means, said method being characterized in that at start a universal heart is built up for receiving a fixing element and fixing the base, then there are integrated to the fixing heart supporting means to support a part and holding means to hold a part to be fixed on the supporting means .
Thanks to this invention, a series of bases could thus be manufactured for fixing a lot of various elements, but from one same base fixing heart.
The advantage of such a method is obvious.
Preferably, the heart is in the form of a pad .
Advantageously, supporting means and holding means are over-molded onto the fixing heart .
The invention will be better understood by means of the following description of the pad forming the core of the base, the fastening base and the moulds for the making thereof, with reference to the appended drawing, wherein:
- Fig. 1 is a bottom perspective view of the base pad; - Fig. 2 is a top perspective view being diametrically cut of the pad of Fig. 1;
- Fig. 3 is a top view of the pad of Fig. 1;
- Fig. 4 is a top perspective view of the pad of Fig. 1;
- Fig. 5 is a side view of an embodiment of the cable fixing base with the pad integrated into the base ;
- Fig. 6 is a top perspective view of two moulds for manufacturing the pad of Figs. 1-4;
- Fig. 7 is a view similar to that of Fig. 6, but rotated by 90° for better seeing the other of the two moulds;
- Fig. 8 is a top perspective view of the two moulds for manufacturing the base of Fig. 5; and
- Fig. 9 is a view similar to that of Fig. 8, but rotated by 90° for better seeing the other of the two moulds .
Considering first the base of Fig. 5, this is thus a base 1, intended for being fixed to a wall 2, to which there should be fixed here a cable 3 through it, and comprising, integrated into it, the elementary pad 10 of this invention, being the component of the base that is to receive an anchoring nail intended to be anchored into the wall 2 for fixing therein the base, a cradle 4 for receiving and supporting the cable 3 and a pair of hooks 5, 6 for maintaining the cable 3 on the cradle 4. In the example being referred to, the base 1 is over-moulded on the pad 10, the hooks 5, 6 extending from the bottom 7 of the base and the cradle 4 is formed from the central parts of the hooks 5, 6.
The elementary pad 10, a universal component (heart) for fixing bases, will be now described.
The pad 10 comprises a nail receiving chimney 11 located at the centre of a cup 12 for receiving the pin guide of a nailer, the chimney and the cup being formed from a pad bottom 13. The cup 12 of a circular general shape, comprises a plurality, here three, of low walls 14 of a band for holding the pad on the pin guide and the same plurality of claws 15 for clamping the pad on the pin guide respectively being interposed between the low walls 14.
The chimney 11 is intended to be introduced into the inner axial bore of the pin guide being in turn able to be introduced into the cup 12 with an inner diameter substantially egual to the external diameter of the pin guide, the section provided by the claws 15 being of slightly lower diameter, but the claws 15 being arranged for being able to be slightly articulated around the foot 16 of the pad bottom. The external diameter of the chimney 11 should be substantially smaller than the diameter of the inner bore of the pin guide, for a reason that will be further explained later on.
When a nail is being anchored into the material of the wall 2 and through the chimney 11, said chimney is crushed under the action of the nail head, the crushed chimney being able to spread inside the cup while acting as a shock absorber for the nail .
The chimney 11, as well as the low walls 14 and the claws 15 of the holding band of the cup 12, is mounted on the bottom 13 of the pad comprising an external reinforcing plinth 17, to come into contact with the receiving wall 2.
The reinforcing plinth 17 provides, upon anchoring the nail through the pad 10, a good distribution of forces and a good distribution of pressure at the surface of the wall being not damaged by the nail impact. The chimney 11 comprises a through bore 18 for receiving the anchoring nail, the front portion 19 of which, with respect to the driving direction for the nail, i.e the portion opening outside the reinforcing plinth 17, has a passing section being tapered towards the front, i.e. towards the external surface 20 of the plinth 17.
Because of such a characteristic, and the diameter of the stem of the anchoring nail thereby able to be easily larger than the passing section of such a front portion 19, such a front portion is subjected, upon the passage of the nail, to an expansion leading to a spread out distribution of the forces of the nail impact at the surface of the wall.
In the embodiment as represented in the drawing, the bore 19 of the front portion of the chimney 11 has a passing section being not only tapered at the front, but being also three-lobed, for allowing nails of different diameters to be guided.
The pad 10 of this invention comprises a front bottom 13 including the reinforcing plinth 17, being bored from one end to the other with compensating holes 21. By means of such holes 21, in the case where the pad 10 is integrated into a base as shown on Fig. 5, the impact forces of the nail will be maintained within the pad 10, the remainder of the base staying saved.
In the example under consideration, three holes 21 are regularly angularly spaced bored, at 120° one from the others, and at the same radial distance from the chimney 11, 19.
Around the chimney 11, there are arranged external ribs 22 for holding the chimney in the inner axial bore of the pin guide, such ribs vertically extending throughout the height of the chimney and, radially, on a diameter substantially larger than the inner diameter of the bore of the pin guide. Introducing the chimney into the pin guide occurs through slightly constraining and bending the ribs 22. This is the reason why the external diameter of the chimney is substantially lower than the diameter of the inner bore of the pin guide of the apparatus an operator will use for fixing the pad/base to the wall.
The base with the pad thereof having been described, molding and over-molding steps for the pad and the base will be now described.
Molding of the pad, the heart of the base
Molding occurs using two moulds 30 and 31, which, considering the structure of the pad, could be referred to as hermaphrodites. Thus, considering the mould 31, the projecting portions 32 will allow for the claws 15 to be molded in the grooves 15', the low walls 14 being formed between the projecting portions 32. The cup 12 is adapted for the central tube part 33 of the mould 31. Similarly, the fingers 34 of the mould 30 allow for the chimney 11 to be made .
Molding the pad here occurs conventionally through cooperation of the two moulds 30 and 31 being introduced one into the other, both moulds being both male and female. The fingers 34 engage inside the volume achieved by the projecting portions 32 and around the central part 33 of the mould 30. After the two moulds 30 and 31 have been assembled, through being brought closer and embedded, conventionally the molding material is injected through the channels 35, 36 shown on the support 37 of the mould 31.
Molding of the fixing base
Similarly to the pad, over-molding occurs using two moulds 38, 39, also assembled through being brought closer and embedded, before the molding material is injected through a channel 40 formed in the support 41 of the mould 39.
Before the two moulds 38, 39 are brought closer, the pad 10 has been threaded onto the stems 42 projecting on the mould 39 through the three holes 21 of the pad, the external surface 20 of the plinth 17 of the pad abutting against the base 43 of the mould 39.
The remainder of the base 1 is thereby over- molded on the pad 10.
On the mould 38, there can be seen the grooves 5', 6' forming the hooks 5, 6 of the base 1. The plinth 7 of the base 1 is molded in the recess 7' of the mould 38.
Through this invention, it is therefore easy, starting from a set of hearts (pads) 10, to over-mould fixing bases of different types.
Has been described the moulding of a base comprising, mounted onto the pad, a supporting cradle and maintaining hooks. Of course, the supporting means and the maintaining means could be combined into unigue supporting and maintaining means, for example a clip, which would be intergrated onto the fixing heart .
