Definitions
- the present invention relates to a method for fixing a spring in the tip of a hollow body and more particularly in the ball point of a writing instrument.
- Ball points comprising an incorporated spring are well known in particular for in the field of correction pens.
- devices with an external spring are known, that is to say devices in which the elastic element is housed in the body of the pen or in an external component at the tip.
- the second category includes devices having a spring integrated into the body of the tip. The process which is the subject of the invention is more particularly interested in this second category.
- One of the difficulties encountered in the manufacture of such pen points lies in the fact of positioning and blocking the spring inside the point.
- a first method consists in fixing the spring by crimping the rear part called the tail of the point. To do this, it is necessary to have a motorized system or a conical hammer which can be difficult to center.
- Another method consists in punching the external part of the point at two or three points. This process is nevertheless difficult to master because it is very sensitive to the thickness of the material to be punched.
- the object of the present invention is to remedy the aforementioned drawbacks by providing a method enabling a spring to be fixed inside a pen tip in a precise, rapid and inexpensive manner. This object is achieved by a process which is distinguished by the features defined in claim 1. Other advantages will emerge from the description which follows and from the features set out in the dependent claims.
- the invention also relates to the tip of a writing instrument obtained by the above method.
- FIG. 1 is a perspective view of the upper part of the body of a pen tip with an internal spring produced according to a known method.
- Figure 2 is a perspective view of the upper part of the body of a pen tip with inner spring manufactured according to the method of the invention.
- FIG. 3 illustrates a pen tip with integrated spring in which the spring is positioned, the tool used being in the rest position. - 3 -
- Figure 4 is a view identical to Figure 3, the punch used to fix the spring in the tip being in contact with the latter.
- Figure 5 shows a view identical to that of Figures 3 and 4, the punch being engaged in the tip of the pen.
- Figure 6 still shows in perspective a pen tip whose spring has been fixed, the punch being in the raised position.
- FIG. 7 is a section along line A-A of FIG. 6.
- FIG. 8 is a section along line B-B in FIG. 6.
- Figure 9 is a top view of a pen tip obtained by the method of the present invention.
- FIG. 1 illustrates an upper part of the body of a pen tip in which an inner spring has been fixed by punching the outer part of the tip at two points. This has the effect of deforming the outer edges of the tip which then hold the spring in position. As explained above, this process is difficult to implement and requires suitable tools.
- FIG. 2 illustrates a pen tip in which the internal spring has been fixed by the method which will now be described with reference to FIGS. 3 to 6.
- FIG. 3 The lower part of FIG. 3 represents a ball point 1 having an internal bore 2 in - 4 -
- This bore 2 has a frustoconical section in its upper part.
- a punch 4 is centered and brought in the axis of the tip 1.
- the end of the punch 4 consists of a first cylindrical part 5, the diameter of which is substantially less than the internal diameter of the spring 3.
- It 4 also has a upper part 6 of triangular or square prismatic shape for example.
- This part 6 has a section the vertices of which can be inscribed in a circle with a diameter between the diameter of the bore 2 formed in the tip and the outside diameter of the body of the tip.
- the diameter of the circle inscribing the vertices of the shape section 6 will be identical to the large diameter of one frustoconical bore of the body of the tip.
- Figure 4 illustrates the punch 4 in an intermediate position, the lower part 5 thereof being engaged in the spring 3.
- the upper end of the spring 3 bears against the shape section 6 of the punch.
- Figure 6 illustrates the end of the cycle, the punch being raised again in the rest position.
- the spring 3 is held in the body of the tip 1 by the shoulder formed by the deformation of the material resulting from the forced insertion of the punch 4 into the - 5 -
- This process is extremely simple to implement since it requires only an axial positioning of the punch 4 relative to the tip 1. It also makes it possible to be able to finely adjust the pushing force of the spring as a function of the depth of the punching.
- the fixing method which is the subject of the invention can be implemented manually or completely automatically according to known techniques.
