Definitions

• the invention relates to a felt-tip pen for labeling posters and the like, with a handle and a writing felt fastened therein, which protrudes at one end from the handle.
• a felt pen is known from DE 33 32 486 C2.
• the writing felt is held in an intermediate piece which is interchangeably fastened to the handle and is located in the handle in contact with a storage body.
• the intermediate piece is tapered towards the writing tip.
• the felt-tip pen can thus be inserted into a funnel-shaped opening of an ink cup until the tip of the writing felt is supported on an absorbent body arranged in the ink cup.
• the ink in the ink cup rises as a result of the capillary action in the absorbent body and soaks the writing felt supported thereon.
• the ink also rises in this due to the capillary action, so that the storage body in the handle is also soaked.
• the ink supply consumed in the felt pen is therefore automatically replenished during breaks in work.
• the felt-tip pen seals little or not at all in the funnel. If you choose the funnel too narrow, the writing tip will no longer reach the absorbent body because the felt tip pen will get stuck beforehand and then also jam strongly. Ink can then no longer rise in the felt pen. It is also not possible to match the dimensions of the funnel, intermediate piece, writing tip length and height of the absorbent body precisely, because wear occurs at the writing tip due to its use and the absorbent body swells somewhat more or less depending on the amount of ink absorbed. In the known design of the felt-tip pen, a certain gap must ultimately be provided between the funnel of the ink cup and the intermediate piece in order to ensure proper functioning.
• the object of the invention is to design a felt-tip pen of the type mentioned at the outset in such a way that a high seal is achieved when inserted into the opening of a congruently shaped ink cup without the felt-tip pen jamming in the receiving opening of the ink cup. Furthermore, the design of the felt-tip pen is intended to prevent the outer contour of the felt-tip pen from being contaminated with ink.
• an axial groove is provided parallel to the felt, which immediately surrounds the protruding end of the felt and is open in the direction of this end, so that the felt-tip pen can be inserted into an opening of an ink pot, wherein a collar surrounding the opening penetrates into the groove, and the writing felt hits an ink-impregnated absorbent body before the collar reaches the groove base.
• This design ensures that ink smeared on the side of the opening of the ink cup cannot get onto the outer contour of the felt-tip pen because this outer contour is never inserted into this opening. Nevertheless, the felt-tip pen can be made quite slim, so that when it is used the view of the writing tip is not obscured.
• the groove and collar of the ink cup can run completely parallel to one another, a small gap remaining on both sides of the collar. Jamming of the felt-tip pen, as occurs in the felt-tip pen according to the prior art due to the conical spacer there, is thus effectively avoided. the. Despite this gap, a good seal is achieved because the gap between the collar of the ink cup and the felt-tip pen is U-shaped and thus forms a so-called labyrinth. For a labyrinth as long as possible, it is constructively advantageous if the depth of the groove is a multiple of its width. The labyrinth effectively prevents the ink from drying out in the ink cup when the felt tip pen is attached.
• the intermediate piece consists of an inner and an outer sleeve which are arranged concentrically to one another, the sleeves being connected to one another by a central web, so that in each case two identical, axial grooves are formed which are parallel to, arranged in the inner sleeve protruding to both sides, felt, and that the handle is inserted and locked in one of the grooves.
• the locking can be achieved simply by forming an inwardly projecting extension that locks the inserted felt in the inner sleeve in the region of the web. The felt is then pressed into the adapter.
• the writing felt protrudes equally far on both sides of the intermediate piece and is designed as a writing tip.
• the intermediate piece has two identical grooves pointing in the opposite direction. With the first, upper groove, it is pushed onto the congruently designed handle until the writing felt protruding into the handle meets the storage body there. The locking between the handle and the intermediate piece is expediently realized by a clamp fit. With the other groove, it is placed on the ink cup as described above. As soon as the first one, out of the felt pen handle If the protruding side of the writing felt is worn out, the intermediate piece with writing felt can simply be pulled off the handle and put back on rotated by 180 °. The second side of the felt is then available for use. The wearing part of the felt-tip pen, namely the expensive felting pen and the intermediate piece connected to it, can be used twice by the design according to the invention, whereby a 50% saving of these parts is achieved in addition to the functional advantages.
• a felt pen 1 with a handle 2 is shown.
• the handle 2 has a cup-shaped part 3 pointing downwards, in which an absorbent storage body 4 is located.
• An intermediate piece 5 is attached to the open end of the cup-shaped part 3.
• This intermediate piece 5 consists of an inner sleeve 7 and an outer sleeve 6, which are connected to one another over their half length by a web 8.
• an extension 9 tapering to the central axis of the inner sleeve 7 is formed within the inner sleeve 7.
• a writing felt 10 is pressed into the intermediate piece 5 and is secured against axial displacement by the extension 9.
• the writing felt 10 protrudes equally far on both sides from the intermediate piece 5 and is designed as a writing surface 13 and 14 at both ends.
• the intermediate piece 5 are accordingly training described two equally deep grooves 11 and 12 were created, which are seen in the drawing up and down open.
• the intermediate piece 5 is pushed with its upper groove 11 onto the open end of the cup-shaped part 3.
• the wall thickness of the cup-shaped part 3 is dimensioned such that it clamps in the groove 11 and can only be pushed into it with a significant force. It is pushed in until the writing surface 13 comes into contact with the storage body 4. To compensate for length deviations, a free space remains in the base of the groove.
• the writing surface 14 When using the felt-tip pen 1, the writing surface 14 will wear and wear. If the permissible dimension is exceeded, the intermediate piece 5, including the felt 10, can be pulled off the cup-shaped part 3 of the handle piece 2 and turned through 180 °, as can easily be seen from the drawing, and put back on. The second writing surface 13 is then available for further use, while the worn end for transporting the ink rests on the storage body 4 in the handle 2. With this design, double-sided use of the relatively expensive writing felt is achieved.
• the felt pen 1 is placed in an ink pot 20, as shown in the drawing.
• an opening 21 is provided in the ink pot 20, which opening is delimited by a collar 22 standing vertically upwards.
• the collar 22 speaks in its shape of the groove 12 of the intermediate piece, but is formed in a somewhat smaller wall thickness than the width of the groove 12 and in a somewhat smaller height than the depth of the groove 12.
• the collar 22 is fastened to a horizontal wall piece 23, which merges into a vertical wall part 24, which merges into a flat part of the one housing 25 of the ink cup 20 after almost twice the height of the collar 22.
• the vertical wall part 24 thus forms a depression 26 surrounding the opening 21.
• In the ink cup 20 there is also a suction body 30 soaked with ink, on which the writing felt 10 stands with its writing surface 14 so that it can suck up full ink.
• this design nevertheless provides a good seal for the felt-tip pen in the ink cup, because this gap runs in an S-shape and thus forms a labyrinth. Gases that are lighter than air trap in the space above the collar 22 and form a barrier there. If gases occur that are heavier than air, they are trapped in the space below the outer sleeve 6. This type of seal is therefore equally suitable for different inks with all possible solvents.
• the special design of the intermediate piece 5 enables the felt to be used on both sides, and at the same time a good seal in the ink cup 20 is achieved with simple, non-jamming handling.
