Description

Hand-held writing instrument as well as a kit to create

at least the outer casing of the housing of a hand-held writing instrument The invention relates to a handwriting device, e.g. B. pencil, ballpoint pen, fountain pen, iaserschreiber, with an elongated housing to hold the writing instrument in the hand.

Such writing implements of the conventional type have a predetermined one Shape. This is disadvantageous in several ways.

So hold z. B. People with different handwriting a writing implement in different ways, depending on whether it is, for example, a precise or is a so-called generous handwriting. Furthermore, the word is how a The writing instrument is held, depending on the size of the hand. Lin Kind, for example, a writing instrument will certainly be different in the old age as an adult.

werner becomes a writing implement depending on the activity performed with him z. B. when sketching, hatching, i'freehand drawing, machine drawing, tracing or held differently when attaching slide markings.

In all known writing implements is because of the given housing or Halters an adjustment to the mentioned dependencies is not possible, which is have an unfavorable effect on the quality of the font or characters and make it uncomfortable Holding the writing instrument can lead.

Accordingly, the present invention resides in. Task based on a To create hand-held writing instrument of the type mentioned, the outer contour of the respective User and the activity to be performed can be adapted.

To solve this new problem it is provided that at least the outer casing of the housing made up of several axially arranged one behind the other, replaceable housing components that are releasably connected to one another in axial weighting exists, of which at least a partial number is in the external shape and possibly differ in the scar.

The housing or the housing jacket of the writing instrument according to the invention is thus made up of individual segments that can be varied with one another can be connected.

Because these segments are at least partially different in their external shape depending on the sequence of the segments, a different outer contour of the is obtained Writing instrument, so that you can adapt to all possible circumstances.

If there are also segments of different colors, will also a decorative effect is achieved.

Another advantage is that the Writing implements are practically impossible due to the great variance in their external appearance is made, d. H. the writing instrument becomes, so to speak, through subjective design to the personality trait.

oops, the user's instinct for play becomes practically unmanageable because of the many possible addition of the segments, whereby through the use of different colors Segments of both systematic and kaleidoscopic changes in color harmony are conceivable.

In addition, the hand-held writing instrument is also available for children and young people is ideally suited to be a children's toy at the same time In addition, design segments in such a way that the writing instrument has a fantasy shape, z. B. an umbrella, an airplane, a rocket, an ish, a snake, etc. results.

The invention also relates to a kit for manufacture at least the outer casing of the housing a hand-held writing instrument, wherein the kit according to the invention is characterized in that it is in axial Direction in any order releasably connectable housing segments Contains different exterior shapes and possibly different scars. the end Such a kit can be used to assemble housings or holders of any shape, as has already been described. It is also possible that the user of the writing instrument by offering supplementary segments, it is possible to create a personal Assortment for different activities that has the character of a coherent collection owns to create.

With all of this, the arrangement according to the invention is extremely cheap, e.g. B. made of metal or plastic.

Appropriate refinements of the invention are set out in the subclaims specified.

Embodiments of the invention will now be based on the drawing described. 1 shows a pencil in longitudinal section with a first one Connection possibility for the housing part, Fig. 2 the longitudinal section of two housing segments that can be connected to one another in another way in an exploded view, Fig. 3a each shows the side view of a writing implement up to 3 o with a different outer contour and Sig. 4a each show the side view of various housings up to 4 r segments.

In Fig. 1, a pencil is shown in longitudinal section, the inner Construction is conventional. In a continuous inner tube in the longitudinal direction 1, a replaceable pencil lead 2 is arranged, which is located on the left in FIG located writing side protrudes to the outside. The inner tube 1 is over the most of its length from a cylindrical part belonging to the pencil case Surround sleeve 3 at a distance. At the end of the cylindrical end facing the writing side Sleeve 3 is screwed into this a connecting sleeve 4, on which from the cylindrical Sleeve 3 protruding part a clamping sleeve 5 with a conically tapering outer circumference is screwed on. The front area 6 of the clamping sleeve which is free from the connecting sleeve 4 5, which is cylindrical on the inner circumference, is the writing-side end of the inner tube 1 assigned. This is designed like a collet at the end mentioned by Longitudinal slots that are open on the end face are present, which form the end of the inner tube 1 divide into distributed over the circumference collet elements 7, 8, which under a radially outwardly directed intrinsic elastic prestress. These collet elements have a Nantelpartie 9, which widens conically towards the outside and the Front part 6 of the clamping sleeve 5 is opposite.

The inner tube 1 is displaceable in the longitudinal direction in the cylindrical Sleeve 3 stored. It is in the space between the inner tube 1 and the cylindrical Sleeve 3 housed a spiral return spring 10, which is on the one hand in front on a radial shoulder 11 of the cylindrical sleeve 3 and on the other hand at the rear a likewise radial shoulder 12 of the inner tube 1 is supported.-This return spring 10 pulls the inner tube 1 with its writing-side end into the cylindrical sleeve 3, until the conical jacket section 9 of the collet elements reaches the front edge 13 the clamping sleeve 5 strikes. The spring force is so great that the leading edge 13 pushes the collet elements radially inwards against their inherent elasticity, so that the pencil lead 2 is securely held. One moves the inner tube 1 with the help of a pressure pin 14 placed on the back against the force of the Spring 10 by hand to the front, the collet elements slide on the front edge 13 of the clamping sleeve 5 over so that they spread open automatically and the mine 2, which can be advanced or replaced in this way.

To this extent, the writing instrument shown in Fig. 1 is known. Both known writing implement, the cylindrical sleeve 3 now forms the outside of the pencil, d. H. this is gripped on the cylindrical sleeve 3.

In the case of the illustrated pencil, there is now an additional one on the outside Housing jacket 15 is provided, which consists of several axially arranged one behind the other Housing segments 16 to 2V. These can be detached from one another in the axial direction tied together. This is used in the embodiment in which the Segments 16 to 20 ring shape with the same inner diameter and all of them Segments penetrating base body in the form of the cylindrical sleeve 3 pushed on are, two from the base body, so from the cylindrical sleeve 3 protruding radially Abutment 21, 22. The two outer segments 16 and 20, respectively, lie with their outer ones End faces on these abutments 21 and 22, which all segments 16 to 20 hold because of each other. The front abutment 21 is annular and clamped between the clamping sleeve 5 and the cylindrical sleeve 3. The rear Abutment 22 is formed by a stepped cylinder, the front cylinder part 3 with a smaller diameter at the end, the cylindrical Iiiilie 3 is screwed in so far is that the step 24 engages the end segment 20 and holds all segments together. So that the segments can be pushed on or removed is at least one of the abutments 21, 22 is releasably attached.

In the exemplary embodiment, the segments 16, 18, 19 and 20 have one cylindrical cover shape with the same liuljdurchrneu:; cr.

The second foremost segment 17, however, has a different outer contour on by extending it backwards from a cylindrical area 25 concavely tapers and merges into the following segment 18 in the shape of a cylinder. Since the inwardly directed concave curvature is all around, there is an annular hollow, which makes it easier to hold the pencil.

From the above it can be seen that the segments are arranged interchangeably are, d. H. one can have the cylindrical segments 16, 18, 19, 20, which are a different one Own length, also in-interchange Attach positions, as well how the segment 17 can be moved.

It can also be seen that you can also work with other segments Can provide external design so that you can adapt to your writing habits as best as possible or to the respective type of writing. It is essential for this adjustment option, that at least a partial number of the segments differs in the external shape. Furthermore, the segments can easily be colored differently, e.g. B.

by making them from different colored plastic.

This results in practically unlimited combination options for the appearance of the housing shell 15.

The internal structure of the writing instrument is related to the present Invention practically meaningless. Corresponding segments can also be found in other writing implements, e.g. B. with ballpoint pens, fountain pens or fiber pens Use as a housing jacket.

In the exemplary embodiment, the loosely adjacent It is very easy to make segments out of metal. However, it is also possible how from Fig. 2 it can be seen to connect the segments to one another in another way, namely by direct attachment z. B. by a front-side latching, with plastic is particularly suitable for this as a manufacturing material.

The annular segments 26, 27, which in Fig. 2 in detached from each other State shown, each have an annular locking bead at one end 28 and one at the other end also circumferential locking groove 29 with essentially complementary shape. The locking groove 29 is slightly undercut, so that the locking bead of the adjacent segment is resiliently clipped into the locking groove can be. With the help of this or a similar locking connection, the segments result a self-supporting structure, so that no abutments for the Zusammerffialtell Segments are required. Likewise, one of the cylindrical sleeve 3 can be corresponding Support part omitted, d. H. the segments 26, 27 directly attached to one another can not only cover the casing of the writing instrument but the entire casing form. In the unsealed by the annular segments interior can for the writing function of the writing instrument required parts used and on be attached in a suitable manner. It is understood that in those cases where the parts required for the writing function are only short of length extend, the segments protruding over these parts also consist of solid material can.

In a modification of the exemplary embodiment according to FIG. 2, it is for example also possible to screw the individual segments together.

Figures 3a to 3 o each show a writing implement 30 to 44 in Side view, with the housing jackets or the housing of these writing implements respectively Segments are composed, which are shown separately in Figs. 4a to 4r are. 3a to 3 o show only some of the practically innumerable possible variations for assembling the segments.

4b shows three segments 45, 46, 47 attached to one another with a cylindrical Outer shape that have the same outer diameter of 8 mm, but which are different in length. The same applies to the representations according to FIG. 4c, 4d and 4e, the outer diameter of these cylindrical segments increases in this row and for the segments according to FIG. 4c 12 mm, for the segments according to Fig. 4d 16 mm and for the segments according to Fig. 4e 20 mm. The shortest Segments 45, 48, 51 and 54 of these segment groups are 5 mm, the longest segments 47, 50, 53 and 56 are 20 mm and the segments 46, 49, 52, 55 are of medium length are 10 mm long.

In FIGS. 4f to 4i, frustoconical segments are shown. 4f again shows three segments 57, 58, 59 attached to one another, the have an equal taper angle and an equal length of 10 mm, in the outer diameter however are different. The larger final outer diameter corresponds to the smallest Segment 57 the smaller end outer diameter of the middle segment 58, the larger final outer diameter the smaller final outer diameter of the largest segment 59 corresponds. The smaller final outside diameter of the smallest conical segment 57 is the same size as the outer diameter of the cylindrical segments 45, 46, 47, which are the cylindrical segments with the smallest diameter. The two final outside diameters of each conical segment 57, 58, 59 differ by such an amount which is the same as the difference in diameter between two cylindrical segments with adjacent outside diameters. In the exemplary embodiment, it is conical Segment 57 at one end as large as the Indian segments 45, 46, 47 and on the other as big as that cylindrical segments 48, 49, 50. The two end-side In contrast, the outer diameter of the conical segment 58 corresponds to the outer diameter of the cylindrical segments 48, 49, 50 or 51, 52, 53. The smaller final outer diameter of the conical segment 59 corresponds to the outer diameter of the cylindrical segments 51 to 53 and the larger end outer diameter of this conical segment 59 is the same size as the outer diameter of the cylindrical segments 54, 55, 56.

The conical segments according to FIGS. 4g, 4h, 4i differ with one another and with the conical segments according to FIG. 4f with the same segment length in the cone angle. Here, the segment 60 is at one end as large as the smallest cylindrical Segments 45, 46, 47 and at the other end as large as the cylindrical segments 51, 52, 53, the segment 61 also corresponds to the outer diameter at the smaller end smallest cylindrical segments 45, 46, 57 and at the larger end the largest cylindrical Segments 54, 55, 56. The conical segment 62 according to FIG. 4i finally corresponds in the outer diameter on the one hand the cylindrical segments 48, 49, 50 with the second smallest Diameter and on the other hand the largest cylindrical segments 54, 55, 56.

4j and 4k also show tapering towards one end Segments 63 and 64, respectively. However, the outer surface of these segments is not conical but is convexly curved, with the surface lines corresponding to an arc of a circle.

In the example, these two segments are åe; eils 15 mm long and their smaller final outer diameter is in each case as large as the outer diameter the smallest cylindrical Segments 45, 46, 47 and like the smaller one Final outer diameter of the conical segments 57, 60 and 61. The larger final outer diameter of segment 63 corresponds to the white diameter of the second largest cylindrical Segments 51, 52, 53 and the larger end outer diameter of the conical segments 58 and 60.

The larger final outer diameter of the segment 64, on the other hand, is about eiiie Step larger and exactly as large as the outer diameter of the largest cylindrical Segments 54, 55, 56 and like the larger end outer diameter of the conical segments 59, 61 and 62.

FIGS. 4q and 4r also show convex segments 65 on the jacket and 66. These segments are, however, much shorter and in the exemplary embodiment only 2 mm long. The final outer diameters of segment 65 are the same as that Outside diameter of the smallest cylindrical segments 45, 46, 47 or the second smallest cylindrical segments 48, 49, 50. The segment 66, on the other hand, corresponds to its two Ends in the outer diameter of the cylindrical segments 48, 49, 50 or 51, 52, 53.

The segments 67, 68, 69 shown in FIGS. 41, 4m, 4n are tapered also towards one end, and they also contain a cylindrical section. The tapering takes place, however, by a concave bulge, whereby the surface lines in turn are formed by an arch of rice. These segments are in the exemplary embodiment the same length as the segments 63, 64 according to FIGS. 4j and 4k. In the final outside diameters the segment 67 corresponds to the conical segment 58, the segment 68 to the conical Segment 62 and segment 69 the conical segment 57. It is understood that in a similar way to the segments after tapering FIGS. 41 to 4n Segments with such Emdaußemdurchmessern can be provided as they are in the other conical segments 59, 60 and 61 are present. the same applies for the rest 4j, 4k, 4q, 4r) show the convexly tapering segments. Here too segments can also be present in addition to the segments 63, 64, 65, 66 shown the end diameters of which correspond to the conical segments 59 and 62.

The segments according to FIGS. 40 and 4p are cylindrical Segments 70 and 71, respectively, which have the same cylindrical shape as segments 53 and 56, respectively which, however, have a trough-shaped recess 72 or 73 have. Depending on the requirements, one could also have more than one such deepening provide. An ijingel can be placed in these depressions 72, 73 when drawing or writing will be inserted if you have such a segment in the area of the writing side of the device attaches.

From the above it can be seen that overall a kit of Segments are present that can be detachably connected to one another in any order are and have different susgen shape and possibly a different color. The kit contains segments 45 to 56 with cylindrical and segments 57 up to 62 or 63, 64 or 67, 68, 69 with at least one part frustoconical, cocave or convex tapered hat shape, with cylindrical segments with different Outside diameters are present and the two end diameters area tapering Segments the outer diameters of cylindrical segments of different sizes correspond. Because of the corresponding Final outside diameter segments with different outer contours can be placed next to one another steplessly. For example, the conical segment 60 can be used as a stepless transition element between the two cylindrical segments -47 and 53 and so on. Further the tapered segments can be attached in both axial positions, d. H. you can swap left and right, so to speak. In this way you can for example, by juxtaposing two segments 68 to achieve an annular trough.

In the exemplary embodiment, there are four different segments for the segments frontal outer diameter, namely 8, 12, 16 and 20 mm. Of course Further outside diameters can also be provided, as can the diameters numerically differently graded. With the four diameters mentioned above However, sufficient diversity for practice can be achieved.

Finally, reference is made to FIG. 4a, in which a conical End segment 74 is shown, at the smaller base of which the outer diameter practically coincides with the inner diameter.
