Definitions

  • the invention relates to a writing instrument with a closure cap sealingly sealing the writing tip, which has at least one substantially axially extending, elastically deformable finger with a cam on its insertion side, which, when the closure cap is slid on, behind a finger lifting shoulder on the shaft of the writing instrument or snaps into place on the writing tip and the cam surface in this snap-in position is operatively connected to the inclined wedge surfaces which are provided over the entire circumference on the shaft of the writing instrument or on the writing tip.
  • annular groove is formed on the shaft, in the boundary wall near the writing tip distributed oppositely inclined wedge surfaces are provided, the radially outermost ends of adjacent wedge surfaces above on the Connecting surfaces lying around the circumference of the shaft and forming a type of tip are connected to one another.
  • the finger to be brought into engagement with the annular groove consists of a metallic spring element with an angled end which forms a cam which, by engaging with the side wall of the annular groove which is further away from the writing tip, prevents the writing tip and the closure cap from separating as long as the cam of the finger does not is pivoted outwards with the aid of the wedge surfaces and is moved out of the region of the annular groove.
  • a writing instrument of the type mentioned at the outset is designed according to the invention in such a way that the cam surface of the finger consists of at least two oppositely inclined cam surfaces which lie essentially in a plane of the circular chord of the circle forming the closure cap opening and which have the smallest radial distance in the region of their cutting line have the longitudinal axis of the closure cap and are shaped in accordance with the wedge surfaces, and that adjacent wedge surfaces intersect to form a common edge which has the greatest radial distance from the central axis of the writing tip.
  • cam surfaces which run out radially inwards to a point and which cooperate with wedge surfaces on the shaft or on the writing tip which taper radially outwards, so that the cam surfaces which strike the wedge surfaces in any position as a result of the Inclination of the wedge surfaces are automatically aligned with the writing tip. Since both cam surfaces and wedge surfaces are tapered, there is no position assignment of the closure cap and writing tip in which the cam surfaces could come to rest on the wedge surfaces without a circumferential force component being present which automatically rotates the closure cap so that the desired one Intervention is achieved.
  • the closure cap can be released by rotating in any direction with respect to the writing tip.
  • the oppositely inclined wedge surfaces can be connected to one another at their end region closer to the front end of the writing tip by the webs forming the locking shoulder, so that the depression for the engagement of the cam of the finger is located behind this connection. Since according to the invention the wedge surface tips protrude beyond the connection areas in this context, the cam surfaces are lifted beyond the wedge surfaces with a corresponding rotation, whereby a resistance-free removal of the closure cap is possible.
  • the areas of the cam surfaces facing the insertion side of the closure cap can be inclined radially inwards to the longitudinal axis and from the insertion side to the inner end. It is also possible, for this purpose, to design the regions of the wedge surfaces facing the front end of the writing tip to be inclined in a radially rising manner from the front end to the lower end. As a result of this inclination, the finger is pushed radially outwards in every position when the closure cap is fitted on, and is thus moved into the area of the wedge surfaces. In this area, the corresponding twisting of the closure cap with respect to the writing tip is then carried out automatically by engagement of the wedge surfaces with the cam surfaces, so that the desired engagement is achieved.
  • closure cap is understood to mean both a conventional push-on cap and a quiver element, as is used, for example, in a writing instrument stand.
  • the writing instrument partially shown is a tube recorder with a writing tip (20), in the front end of which a writing tube (22) is held.
  • a conventional ink compensation chamber not shown, is covered by a sleeve (21) which can be pulled off towards the writing tube (22) in order to expose the ink compensation chamber for cleaning.
  • wedge surfaces are arranged on the circumference of the writing tip (20), of which only the wedge surfaces (23, 24, 27, 28) are designated. These wedge surfaces are flat, and the wedge surface (27) rises, for example as seen from the writing tube (22) in a clockwise direction, i. H.
  • the web (25) connects the wedge surfaces (23) and (24) and the web (29) connects the wedge surfaces (27) and (28).
  • the remaining wedge surfaces are connected to one another in the same way by webs not designated.
  • the height of the webs is less than the tips of the wedge surfaces, which result from the intersection of two adjacent wedge surfaces and one of which is designated by (26).
  • the wedge surfaces and the webs are formed in one piece with the writing tip (20).
  • the closure cap has a sleeve (1), preferably made of plastic, which has a groove (6) on its left end in FIGS. 1 and 2 for receiving the fastening end of a clip (6 ').
  • the clip is held in place by a cup-shaped insert (3) and an insert button (2).
  • An elastic seal (4) is located in the bottom area of the insert (3), and an elastic ring seal (5) is provided on the end face of the insert (3) on the right in FIG.
  • the ring seal (5) seals the annular space between the writing tip (20) and the sleeve (21), while the front end of the writing tube (22) is closed by the seal (4).
  • the spring (16) provided between the insert button (2) and the insert (3) presses the insert (3) and thus the seal (4) and the ring seal (5) against the writing tip.
  • An elastically deformable finger (8) is formed in the sleeve (1) by axially extending incisions (7), of which only one incision can be seen in FIG. 2.
  • Cam surfaces are formed on the free end of the finger (8) and on the remaining wall of the sleeve (1) in the region of the insertion opening, that is to say at the level of the free end of the finger (8). These cam surfaces are flat and run at the same inclination as the wedge surfaces of the writing blocks. For example, the cam surface (9) rises clockwise from the left end of the sleeve (1) in FIG.
  • the cam surface (11) reduces its distance from the central axis of the sleeve (1) during the transition from the cam surface (10) to the cam surface (12) and the cam surface (12) runs in the same way as the cam surface (10).
  • the cam surface (13) recognizable on the finger (8) (FIGS. 1 and 2) is one of two cam surfaces formed on this finger (8).
  • cam surfaces on the finger (8) of which only the cam surface (13) can be seen in FIGS. 1 and 2.
  • a further group of cam surfaces (9, 10, 11, 12) is provided in its opening area.
  • a corresponding group of cam surfaces is offset by 120 ° in the opening area of the sleeve (1).
  • the cam surfaces on the opening side of the sleeve (1) are chamfered, so that axially and radially inward from the opening side Surface areas (14) and (15) are formed.
  • these inclined surfaces (14, 15) and the corresponding inclined surfaces on the finger (8) either come into engagement with the ends of the wedge surfaces projecting to the left in FIG. 1 or with the webs (25, 29).
  • the slanted surfaces slide over the contact surfaces on the writing tip (20) and the finger (8) is pivoted radially outwards.
  • the cam surfaces (9), (10, 11, 12, 13) can slide over the webs (25, 29) and reach the area of the wedge surfaces (23, 24, 27, 28), which are to the right in FIG Webs (25, 29) lie.
  • the oblique cam surfaces come into engagement with the wedge surfaces, and the cap is rotated due to the pressure exerted by the elastic finger (8) and the resulting sliding movement of the cam surfaces on the wedge surfaces so that the wedge surfaces are flat in their area Rest cam surfaces.
  • the closure cap can no longer be removed from the writing tip (20) because the cam surfaces or the projections forming the cam surfaces engage behind the webs between the wedge surfaces of the writing tip (20).
  • the cap and the writing tip (20) are rotated relative to one another.
  • the cam surfaces of the sleeve (1) slide on the wedge surfaces of the writing tip (20), and the finger (8) is thereby pivoted radially outwards.
  • This sliding of the cam surfaces along the wedge surfaces must be continued until the radially innermost areas of the cam surfaces, for example the cutting edge of the cam surface (9) and cam surface (10) (FIG. 2), are above the webs (25, 29) ) is located.
  • the cam surfaces or the projections forming them are moved radially further outward than the height of the webs (25 and 29).
  • the cap is shifted to the left ( Figure 1) due to the elasticity of the ring seal (5) and the seal (4) and the action of the spring (16) and can be removed from the writing tip (20).
