Definitions

  • the invention relates to a cap for a writing instrument, to which a clip with an approximately right-angled retaining eyelet, which is penetrated by a pen in the cap, is attached.
  • Such a cap as can be used for example for fountain pens, ballpoint pens, etc., is known from DE-A-1 561 847.
  • the known cap is provided with a clip which has a retaining ring projecting approximately at right angles from the longitudinal direction of the clip.
  • the cap has a cap screw at the tip, which is screwed into the tip of the cap and passes through the opening of the retaining ring, thereby tightening the retaining ring in the cap. If the clip is to be changed, the cap screw must be loosened and completely removed from the cap, then the new clip put on, the cap screw inserted through the ring opening and then tightened again on the cap. For a user who wants to replace the clip on the cap of the writing instrument with another, this process is relatively complex in the known construction.
  • the clip is held in the cap with its retaining eyelet, which projects essentially at right angles, by a pin which extends through the eyelet.
  • the cap has a recess on the side into which the retaining eyelet can be inserted.
  • the pin has a main part in the longitudinal direction and a section which has a reduced extent transversely to the longitudinal direction of the pin compared to the main part.
  • the pin is displaceable in the longitudinal direction so that either the main part or the section with reduced transverse expansion passes through the opening of the retaining eyelet.
  • the retaining eyelet On the area of its circumference facing away from the clip, the retaining eyelet has an open cutout, the width of which is greater than the transverse extent of the section and smaller than that of the main part of the pin.
  • the eyelet can be inserted through the recess in the cap and pushed with its open cutout over the pin, namely over the section with reduced transverse expansion, and locked to the pin by moving it in the longitudinal direction so that the main part Reaches through the opening of the eyelet.
  • a spring force is applied to the pin, which presses it into a rest position, in which the main part lies in the opening of the retaining eye.
  • the clip is locked with its holding eyelet in the rest position of the pin on the main part of the pin, since the open cutout of the holding eyelet has a smaller width than the main part of the pin.
  • the pin is moved against the spring force so that the section of the pin with reduced transverse expansion passes through the retaining eye, whereby the retaining eye with its open cutout can be pulled off the pin.
  • the main part and the section of the pin with reduced transverse expansion are cylindrically shaped and arranged coaxially to one another, and the opening of the retaining eye is circular.
  • the transverse extent, i.e. the outer diameter of the section is smaller than the width of the open section of the holding eyelet, while the outer diameter of the main part is larger than the width of the open section of the holding eyelet.
  • the outer diameter of the main part is only slightly smaller than the inner diameter of the opening of the holding eyelet, so as to ensure that the holding eyelet sits on the pin without play.
  • the pin is guided in a central bore in the cap and a head is attached to the pin, which protrudes beyond the tip of the cap.
  • the section with reduced transverse extent adjoins the head, and the main part adjoins the end of the section with reduced transverse extent facing away from the head.
  • a helical spring attaches which pushes the head and the pin connected to it outwards. The user can easily remove the clip by pressing on the head at the top of the cap, thereby moving the section with reduced transverse expansion into the area of the holding eyelet. The clip with the open peripheral cutout of the retaining eyelet can then be removed from the section of the pin.
  • the clip to be reinserted is pushed in a corresponding manner with its retaining eyelet over the section of the pin and then the head of the pin is released again, so that the pin returns to its rest position and the retaining eyelet is penetrated by the main part of the pin and in this way on the cap is locked.
  • FIG. 1 shows a cap 2 with a clip 4 attached to it, which extends in the longitudinal direction over the outer surface of the cap 2.
  • the clip 4 has at one end a substantially right-angled retaining eyelet 6, which is inserted laterally into a recess 3 in the cap 2.
  • a perspective view of the clip 4 is shown in FIG.
  • the clip 4 has an elongated area which is intended to lie over the outer surface of the cap 2.
  • the eyelet 6, which has an opening 5, projects from the elongated area at approximately a right angle.
  • the holding eyelet 6 has a cutout 7, 7 ′ in its front area with which it is inserted into the recess in the cap 2, so that an open peripheral area is formed at the opening 5 of the holding eyelet 6.
  • the cap 2 has a central bore 8 in the front area, which is expanded near the tip to a bore 10 with a larger diameter.
  • a pin is guided in the bores 8, 10 of the cap 2, which has a main part 14 and a section 12 with reduced transverse expansion in the longitudinal direction.
  • the main part 14 and the section 12 are cylindrical, the section 12 having a reduced transverse extent, ie in this case a reduced outer diameter compared to the main part 14.
  • the section 12 is coaxially attached to the main part 14.
  • a head 16 is attached which projects beyond the tip of the cap 2.
  • a helical spring 20 engages, which acts on the pin with an outward force.
  • the pin Due to the spring force, the pin is pulled into a rest position, in which the main part 14 lies in the opening 5 of the retaining eyelet 6 and the end face of the main part 14 lies against a front stop surface 9 in the bore 8.
  • the engagement of the main part 12 with the holding eyelet 6 fixes the holding eyelet 6 and thus the clip 4 against movements transverse to the longitudinal direction on the pin.
  • the main part 14 and the section 12 of the pin are cylindrical and the opening 5 of the retaining eyelet 6 is circular, as can be seen in the cross section in FIG. 2; the outer diameter of the main part 14 is only slightly smaller than the inner diameter of the opening 5 of the holding eyelet 6, in order thereby to ensure a play-free fit of the holding eyelet 6 on the main part 14 of the pin.
  • the locking mechanism for the clip is shown in cross section along the line II-II of Figure 1.
  • the retaining eyelet 6 of the clip 4 is pushed with its open peripheral cutout 7, 7 'over the section 12 of the pin.
  • the section 12 has an extent transverse to the insertion direction of the retaining eyelet 6, i.e. an outer diameter that is smaller than the free width of the open peripheral cutout 7, 7 '. In this way, the eyelet 6 can be pushed transversely to the longitudinal direction of the pin over the section 12, so that the pin passes through the opening 5 of the eyelet 6.
  • the main part 14 with a larger diameter is brought into the area of the opening 5 of the holding eyelet 6, whereby it is locked in the direction transverse to the longitudinal direction of the pin, since the diameter of the second section 14 is larger than the open peripheral cutout 7, 7 'the eyelet.
  • the user presses on the head 16 and thereby moves the pin so far out of its rest position that the section 12 with a reduced diameter lies in the area of the holding eyelet 6.
  • the clip 4 can then be removed in the transverse direction from the pin by the open cutout 7, 7 'passing the section 12 with a reduced diameter, and the Retaining eyelet 6 are laterally pulled out of the recess 3 from the cap 2.
  • the user then inserts a new desired clip with its holding eyelet 6 laterally into the recess 3 in the cap 2, the head 16 of the pin being held down, the holding eyelet 6 with its open peripheral cutout 7, 7 'pushes over the section 12 of the pin and then lets go of the head 16 so that the spring force pulls the pin into its rest position and thus the main part 14 into the opening 5 of the retaining eye 6 and thereby locks the new clip on the cap.
  • the function of the locking mechanism can also be realized with other configurations of the section 12 and the main part 14 of the pin.
  • the section 12 and the main part 14 of the pin are cylindrical and the opening 5 in the retaining eyelet 6 is circular.
  • the section 12 and the main part 14 of the pin are, for example, rectangular or polygonal in cross section, it only being necessary to ensure that the main part has a greater extent transversely to the insertion direction of the holding eye than the open peripheral region of the holding eye has so that the main part when reaching through the opening of the retaining eyelet locks it in the insertion direction, while the transverse extent of the other section transversely to the insertion direction of the retaining eyelet must be smaller than the extent of the open peripheral region so that the retaining eyelet with its open peripheral region is pushed over the section can be.
  • the opening 5 of the holding eyelet 6 would be designed to be complementary to the cross-sectional shape of the main part 14 with slightly larger dimensions, so that there is a play-free, positive engagement of the second section 14 into the opening 5 of the holding eyelet 6.
  • the section with reduced transverse expansion and the main part in the longitudinal direction of the pin can also be reversed be arranged.
  • the pin must then be pulled outwards against the spring force in the direction out of the cap in order to bring the section with the smaller diameter into the area of the holding eye.
  • the spring force pushes the pin into the cap and the main part of the pin into the opening of the retaining eye.
