Definitions

  • the invention relates to a capillary spaces writing element for a writing, drawing or application device, with a socket that has a tubular sleeve that is formed with a front end portion with an internal cross-section adapted to the writing element, the writing element on the front with an application portion and protrudes from the sleeve with a line section on the back.
  • Such a writing element can, in a known manner, be different designs of sintered porous capillary-promoting material, laminar fiber material, the is solidified by means of a known method in order to extruded capillary-promoting material or the like. act.
  • a capillary-promoting writing element which protrudes from a socket on the front with an application section.
  • the writing element also protrudes from the socket with a line section on the back.
  • the socket is composed of a number of individual parts.
  • Another writing device of this type is used in particular as a so-called fineliner with a diameter of around 0.5 mm.
  • this known writing element in the form of a finliner, the front edge of the front end section of the sleeve is rolled toward the writing element in order to mechanically firmly connect the sleeve to the writing element.
  • This rolling in of the front edge results in a notch effect on the writing element, by which the ink flow through the writing element in particular can be impaired because the front edge of the sleeve is only a relatively small distance from the writing tip of the writing element protruding from the sleeve.
  • Esp. in fine liners with a diameter of the order of 0.5 mm there is often a kinking of the tip of the writing element, i.e. a rigid connection between the writing element and the sleeve. unavoidable of their free end portion protruding from the sleeve, which leads to such a writing, drawing or application device becoming unusable.
  • the invention has for its object a writing element of the type mentioned, esp.
  • a writing element for to create a fineliner in which kinking or splicing or an inability to use the writing element as a result of excessive writing pressure is avoided by simple means.
  • the sleeve has only a relatively small axial longitudinal extent, the writing element, which is in particular a so-called fineliner, with its front end section with the writing tip being relatively short and with its rear end section being relatively far out of the way Protrudes sleeve.
  • the rear line section of the writing element preferably has an axial longitudinal extension which is many times longer than the axial longitudinal dimension of the sleeve.
  • the spring element provided between the sleeve and the writing element is fixed with its front end section at a relatively large axial distance from the writing tip on the writing element, the core effect lies at a suitable point and is easy to control, since it leads to a reduction in the ink flow Holding force can be smaller than with a fixed fixation.
  • According to the invention is fixed at a different location and with a lower intensity, so that not only the ink flow is less obstructed, but also the risk of kinking the Writing tip of the writing member is advantageously reduced.
  • Another advantage is that the writing member is guided by the front end portion of the sleeve so that it can move linearly, so that up to high writing pressures with respect to the sleeve and thus in relation to the writing, drawing or application device the sleeve of the writing element is fixed, resulting in an inwardly resilient lead.
  • This is particularly advantageous for fine liners with a diameter of around 0.5 mm.
  • the principle according to the invention can also be used for writing elements with a larger diameter of up to approximately 2 mm.
  • the spring element is fixed with its front end section to the writing element by means of a ring element.
  • a ring element has expediently been used, which can be pushed onto the writing element in the unloaded idle state and which is clamped against the outer lateral surface of the writing element in the fixing state with a defined clamping force which does not interrupt the capillary spaces of the writing element.
  • the ring element can simply consist of a relatively soft or, for example, indented, of a plastically flexible material.
  • the ring element can also be rivet-like or the like. trained and caulked with the writing element, ie be crimped to the writing element.
  • the ring element can be easily pushed onto the writing element in a first working step for producing the writing element and then clamped, ie fixed, on the outer surface of the writing element at a predetermined distance from the writing tip.
  • the spring element is then pushed onto the lead from the rear until it rests on the ring element with its front end section.
  • a ring made of a relatively soft material can, for example, be caulked, ie pressed together, or a sleeve or rivet can be rolled or crimped, as has already been stated.
  • the spring element is fixed with its rear end section to a contact collar formed on the rear sleeve section.
  • the contact collar is formed by a crimped edge section of the sleeve.
  • the ring element for fixing the front end section of the spring element on the writing element is preferably made of a metal.
  • the sleeve surrounding the spring element can consist, for example, of stainless steel or of a suitable plastic material.
  • the spring element is a tubular sleeve made of an elastically resilient plastic material.
  • the tube sleeve can e.g. also with holes, ribs, slits or the like. be trained.
  • the writing element consists of a plastic material which has a central area forming the capillary spaces and has a dense casing surrounding the central area.
  • Such writing organs are known per se, so that there is no need to go into them in detail. If necessary, it would of course also be possible to implement the writing element from a fiber or wick material.
  • an impregnated fiber body is usually used in a writing, drawing or application device with a writing element according to the invention as a memory for the writing medium
  • the fluidic connection between the fiber body and the writing element if the writing element has a rear end section, of which the jacket, which surrounds the central area forming the capillary spaces, is at least partially removed.
  • This end section can, for example, be tapered towards the rear end of the writing element.
  • the rear end section of the writing member is formed with a side surface oriented parallel to the longitudinal center line of the writing member.
  • Such a configuration of the rear end section prevents gaps between the storage of the writing fluid and the resilient writing element at all times, so that there is always a uniform ink flow from the storage to the writing element.
  • Another advantage of the writing element according to the invention is the elastic writing feeling which results from the resilient design of the writing element in relation to the sleeve. Furthermore, there is the advantage that the writing element is secured against breakage or against splicing due to its resilient flexibility.
  • Figures 1 to 5 are drawn on a large scale in various scales to clarify the essential details of the writing element.
  • Fig. 1 shows a writing element 10, which is a fineliner lead of a writing, drawing or application device, and which is provided with a holder 12, which is a tubular sleeve 14.
  • the sleeve 14 has a front end portion 16 and a rear Sleeve section 18.
  • the front end section 16 of the sleeve 14 has clear internal dimensions which are adapted to the cross-sectional dimensions of the fineliners, so that the front end section 16 is suitable for guiding the writing element 10.
  • the rear sleeve section 18 has an internal cross section that is larger than the cross-sectional dimensions of the writing member 10, so that an annular space 20 is provided between the writing member 10 and the rear sleeve section 18.
  • the annular space 20 serves to receive a spring element 22 which is fixed with its front end section 24 to the writing element 10 by means of a ring element 26.
  • the rear end section 28 of the spring element 22 is fixed on the rear sleeve section 18 or on a contact collar 30 of the sleeve 14.
  • This contact collar 30 is a crimped edge section 32 of the rear sleeve section 18 of the sleeve 14.
  • the spring element 22 is designed as a tubular sleeve which consists of an elastically flexible plastic material.
  • a spring element 22 is indicated in sections, which is, for example, a coil spring made of a wire material.
  • the spring element 22 is provided coaxially with the writing element 10.
  • the ring element with which the spring element 22 is fixed with its front end section 24 on the writing element 10 is also designated in FIG. 2 with the reference number 26.
  • the ring element 26 in the original state is indicated with thin dashed lines in FIG. 2.
  • the ring element 26 is dented conically. If a force is exerted on the ring element 26 in the direction of the arrow 34 (see FIG. 2), there is a reduction in the inner diameter of the ring element 26 and consequently a clamping of the ring element 26 on the writing element 10. This clamping is in this case such defines that the ink flow through the writing element 10 is not impaired.
  • FIG. 3 A cross section through the writing element 10 is indicated on a greatly enlarged scale in FIG. 3, it being apparent from this figure that the writing element 10 has a central area 38 forming the capillary spaces 36 and a dense jacket 40 surrounding the central area 38.
  • the writing element 10 protrudes from the sleeve 14 with a writing tip 42. Furthermore, it can be seen from this figure that the writing element 10 protrudes from the rear of the sleeve 14 with a line section 44, which is shown in broken lines.
  • the line section 44 has a rear end section 46 from which the jacket 40 (see FIG. 3) is at least partially removed.
  • the rear end section 46 of the writing element 10 is expediently provided with a cylindrical surface 48, i.e. formed with a side surface which runs parallel to the longitudinal center line 50 of the writing element 10.
  • Such a writing instrument is manufactured, for example, as follows: In a first step, the ring element 26 is pushed onto the writing element 10 and localized at a predetermined location. A force is then exerted on the ring element 26, as indicated by the arrows 34 in FIG. 2 is, whereby the ring member 26 is fixed to the writing member 10. In the next step, the spring element 22 is pushed onto the writing element 10 from the rear end section 46 until its front end section 24 rests on the ring element 26 clamped on the writing element 10.
  • the sleeve 14 is pushed onto the thus prepared writing element 10 from its writing tip 42 until the transition section 56 of the sleeve 14 between its front end section 16 and its rear sleeve section 18 is in the vicinity of the ring element 26. Thereafter, the rear edge portion 32 of the sleeve 14 or its rear sleeve portion 18 is flanged, so that the spring element 22 rests on the one hand with its front end portion 24 on the ring element 26 and on the other hand with its rear end portion 28 on the flanged edge portion 32 of the sleeve 14. In this way, the spring element 22 between the sleeve 14 and the writing element 10 is defined in a precisely defined manner. This definition results in the spring element 22 not being mechanically tensioned in the unloaded rest position of the writing element 10 relative to the sleeve 14.
  • the writing element 10 assembled in this way with the sleeve 14 can then be inserted into the housing 54 of a writing, drawing or application device. If, when writing or drawing with such a device 58 or with its writing tip 42, it is pressed against a base, the writing element 10 can move axially into the housing 54 with the stationary sleeve 14, the spring element 22 being mechanically tensioned. If the writing pressure ceases to apply, the spring element 22 can relax again, so that the writing tip 42 of the writing member 10 moves out of the housing 54 again. This results in a spring-loaded writing element 10, which has a good elasticity Writing feeling results. In addition, an even ink flow and excellent break resistance is achieved.
  • a writing instrument with a writing element designed as a wick in which the wick is resiliently mounted in the longitudinal direction in the housing of the writing instrument.
  • a spring element is used, which has a spring constant between 50 and 600 g / cm.
  • the spring element is not provided there, however, between the writing element and a sleeve surrounding the writing element, but between a closure cap and the back surface of a memory for the writing medium arranged in the housing of the device.
  • this known writing instrument cannot be compared with the writing element according to the invention, which is only comparable with the writing wick, which is thin in comparison to the storage wick, and the writing tip of the writing instrument surrounding the writing wick.
  • FIG. 4 shows, on a greatly enlarged scale, a section of an application member 10 with a ring element 26, which is drawn with thin dashed lines in the initial or original state and hatched with solid lines in its operating state caulked with the application member 10.
  • the ring element 26 is designed as a simple, flat ring, which preferably consists of a relatively soft, plastically deformable material.
  • the application element 10 is inserted with its front side or with its writing tip 42 (see FIG. 1) into a suitable receptacle. Then the ring element 26 is pushed from the rear end section of the writing element 10 onto the writing element 10.
  • a blow is then made on the ring element 26 exercised, which is indicated by the arrows 60.
  • the reaction force exerted on the ring element 26 by the aforementioned (not shown) receptacle is indicated by the arrows 62.
  • the action and reaction force 60, 62 compresses the ring element 26, ie reduces its thickness and at the same time increases its radial dimensions, so that if the ring element 26 is suitably dimensioned, it is jammed on the application element 10 without the capillary behavior of the application element 10 affect.
  • FIG. 5 shows an embodiment of the application element 10, drawn in sections on a greatly enlarged scale, with a ring element 26 which is designed as a rivet.
  • This rivet-shaped ring element 26 is fixed to the application member 10 by caulking or flanging without impairing the capillary action of the application member 10.
