Description

The The invention relates to a pen with a permanent at one end attached magnetic element.

to Achieving new design freedom in terms of design from pen holders, as well as to the improvement the order at the workplace with respect to pens It is sometimes desirable to use the pens with a magnetic holder are provided so as to a To be able to attach steel holders in a simple form. For this purpose, often the brackets with the necessary magnetic elements provided and in return here the pen with a stainless steel case provided so as to be able to pin the pen. Furthermore, there are complex design solutions, where the pen is provided with a special magnet is, thus by the magnetic forces effective stand to realize for these pens. In any case In such solutions, it requires expensive and expensive Construction of both the pen, and in particular the Bracket.

This In many cases leads to corresponding mounts very are expensive and are only used in individual cases.

For simplicity, the font shows US 3,159,372 A a magnetic holder for a pencil. Here, a U-shaped element is clipped on the side of the pencil. This U-shaped element is a magnet, thus ensuring that the pencil can be attached to a steel plate. By choosing the clamping force of the pencil in the holder can be determined whether preferably the holder should adhere to the steel plate and thus the pencil is pulled out of the holder, or whether the pencil and holder is released from the steel plate. For the user both attachment points are available in any case.

To avoid the problem that the holder unintentionally dissolves from the pencil, an alternative holder, such as this one from the font US 2,594,955 A is disclosed used. With regard to the mounting principle, this largely corresponds to the previous solution, wherein the holder consists of a cylindrical body with laterally attached magnet. This ensures that in unfavorable pulling direction on the pencil, the magnet does not remain on the metal plate, but is replaced with the pencil.

In this respect, it is possible with the two aforementioned solutions to attach the pen parallel to its longitudinal extent on a steel surface. Another comparable solution shows the font US 2,644,212 A In this case, an additional element is provided, by means of which not only the magnetic holder can be used, but also a conventional from pen writing clamp.

Although it is possible with the aforementioned solutions, Pens in a simple manner by means of a magnet still remain disadvantages in terms of Ergonomics, as well as the designerischen freedom. In particular it is not possible with the illustrated solutions to fix the pin at one end in such a way that the axis of the Stylus is perpendicular to the metallic contact surface. This may be desirable if, for example, a horizontal steel surface is present on which the pin should be placed vertically or under the pen vertically should hang. Second, it is disadvantageous that the additional Holder on the pin of the prior art this in scope increases and thus significantly more space in the Stowage of the pen, for example in a jacket pocket, required.

task The present invention is therefore, the design freedoms and starting the attachment possibilities of a pen from the prior art to improve that this is the usual Dimensions of a pen does not or only slightly exceeds and to an end perpendicular to a steel surface can be placed.

Solved The object is achieved by the inventive design according to claim 1.

advantageous Embodiments are subject of the dependent claims.

One generic pen includes in each Trap a write mine and the writing mine surrounding pen body. According to the basic function of the pen can on At a first end, the writing lead protrudes from the pen body. The size of the pen body is initially characterized by a pin cross-section.

Characteristic for the invention it is that at the second end of the pen in and / or on the pen body a magnetic element insoluble is attached. To achieve the object, the invention proposes that the magnetic element in cross-section less than or equal to the pin cross-section is selected.

The arrangement of the magnetic element at the second end follows from the fact that at the first end, it is known that the writing lead has to protrude from the pen body. In this respect, the available space at the second end is greater than at the first end, in particular taking into account that the cross section of the magnetic element should not be substantially larger than the pin cross section.

For It is obvious to the person skilled in the art that the pin cross-section does not come with it must be round. Rather, this can be any external shape have, for example, with an ellipse-shaped or hexagonal Cross-section. Furthermore, it is obvious that the pin cross section over the length of the pen is not must be constant. In this respect, the relative statement of the Cross section of the magnet on the largest pin cross section, d. H. of the pen body, but without consideration of additional attachments, such as a clip.

The Arrangement of the magnetic element coaxial with the axis of the pen may be advantageous because in many cases the production the pen is simplified with magnetic elements.

First by the inventive design of the pen it is achieved that this by means of the magnet not only in known way can be attached, but rather also about his front end on a perpendicular metal plate. By the advantageous choice of the cross section of the magnetic element It is also achieved that the pin stows easily can not and thus takes up more space than a pen without corresponding magnetic element. In this respect, this improves the ergonomics and handling as well as the acceptance, a corresponding To use pen.

Especially to advantage the invention is sufficient if this in a pen is used, which has a substantially constant pin cross-section having. In comparison with the prior art shows in particular in this feature, the advantage of the invention Execution. If you have the magnetic U-shaped Holder of the prior art, as described above, selects and moving it to one end of the pen would be it also conceivable, the pen on the front end to place on a steel plate. However, only one would be half benefit, while on the other hand by the inventive Solution especially with constant pin diameter especially the advantageous embodiment comes into play and the Pen according to the invention now no longer Space to stow, as a pen without magnetic element.

Especially advantageous is the embodiment of the invention when used on a commercial pencil. insofar The pen consists of a pencil with one in one Create a pen body embedded graphite mine. To the Pencil can insofar advantageously the magnetic element be fastened by means of a ferrule. In a further embodiment it is possible, by means of the ferrule another means to attach, this being an eraser as a rule becomes.

at an application of the solution according to the invention with a pencil can be the regular one in an advantageous way Embodiment be used, with the existing Fastener of the ferrule at the same time the corresponding magnet can be attached. In this respect, no elaborate mounting method is required for the magnet or additional processing of the pencil in front of a fastening of the magnet.

alternative for execution with a ferrule, it is also conceivable the magnetic element on the pen body by means of an adhesive bond to fix. Here, the magnetic element at the second end of Pen body attached. In particular, this embodiment is suitable if it is a particularly suitable for gluing Material acts.

In Further alternative, it is advantageous if the magnetic element at least in sections, in particular completely, from The writing body is surrounded. In this case will turn arranged the magnetic element at the second end of the pen and is located in extension of the writing mine. By the Introducing the magnetic element in the writing body on the second End of the stylus becomes a particularly simple attachment of the magnetic element achieved, without necessarily for this purpose further Fasteners required. This is usually the magnetic element, at least when looking at the second end of the pen, off look out the writing body.

Especially simply the structure of the invention Pen is when the cross section of the magnetic element substantially the Cross section corresponds to the writing lead. Through this design is the installation of the magnetic element in the writing body especially simple and requires no complex editing or design of the pen body.

Taking into account the possible manufacturing method, it is particularly advantageous if, comparable to previously executed solution, the magnetic element is partially surrounded by the writing body. In this case, in turn, the magnetic element is arranged at the second end of the stylus and is in extension of the writing lead. Likewise, a particularly simple attachment of the magnetic element is achieved by the introduction of the magnetic element in the writing body at the second end of the stylus, in addition a bond can be used to ensure a tight fit. Here, the magnetic element is not surrounded by the pen body at least on one side.

deviant from the solution, the magnetic element in the cross section of the write mine and / or coaxial with the pen, it is thus possible, this magnetic element eccentric to the write mine to arrange and this one-sided from the writing body to look out.

In Continuation is advantageously the magnetic element not on two opposite sides of the pen body surrounded and thus it is possible, for example, a simple rectangular, block-shaped magnetic element to use which is placed over the middle in a slot at the end of the Pen body is inserted.

These Design is particularly suitable when the installation of the magnetic element done in the writing body in such a way that the necessary Installation space by means of a machining, in particular milling, is produced. For this purpose, a groove in the pen be introduced without magnetic element and accordingly a block-shaped Magnet element can be used herein.

to Generation of the necessary installation space for the magnetic element There are various options available. If the production of the pen without magnetic element in endless takes place and is produced by sawing to length is advantageously a mechanical processing, such as Drilling or milling, chosen.

Likewise However, it is also possible for single generation of the pen without magnetic element here in the manufacturing process the write mine shorter than the pen body fail thus the released volume for the magnetic element to use.

For this The following figures outline example embodiments the inventive design of a pen.

The 1 shows a first example of the embodiment of a pen according to the invention 01a , This first appears like an ordinary commercial pencil 01a , In this respect, this includes a writing mine 03a which from the pen body 02a is surrounded. By means of a ferrule 04 becomes an eraser 05 held.

Apparently, the embodiment of the pen according to the invention 01a only when looking at the longitudinal section in 2 concerning the solution 1 , The pen is visible again 01a with a writing mine 03a which from the pen body 02a is surrounded. At the end of the pen body 02a is finally the magnetic element 06a arranged. This will be at the pen body 02a by means of a ferrule 04 held, this at the same time an eraser 05 attached.

It is obvious that it is possible with the ferrule 04 both the magnetic element 06a to fix as well as by means of the ferrule 04 other means, such as decorative elements, on the pen 01a to keep.

If only the magnetic element 06b at the end of the pen body 02a must be attached and in this case the pen body 02a is suitable for attachment by gluing, so a solution according to 3 to get voted. In this case, a particularly simple embodiment of the pen 01b given when the magnetic element 06b is attached by means of gluing on the pen without magnetic element, or on the pen body with write lead.

The 4 shows in longitudinal section an embodiment of a pen 01c with the same pen body unchanged 02a , but shortened writing mine 03c , In the volume fraction around which the write mine 03c is shortened, here is a paragraph of the magnetic element 06c be used. In this respect, by inserting the magnetic element 06c in the pen body 02a the attachment will be possible.

An improved grip over previous solution ensures the embodiment according to 5 , In this case, the pen has 01d a magnetic element 06d which completely from the pen body 02d is surrounded. For this purpose, in the pen body 02d , For example, by drilling, appropriate recording volume can be created.

After inserting the magnetic element 06d Thus, only the end face of the magnetic element is located 06d open.

A particularly secure attachment of the magnetic element 06e , as well as a particularly simple installation in the pen body 02a , show the 6 with the pen 01e , By using one opposite the pen body 02a shortened writing mine 03c can at the volume of the magnetic element 06e be used. It is again possible to drill the necessary volume freely, as well as to use a shortened mine.

Unless the write mine 03a has a higher stability, it is also possible to use the magnet 06f form as a sleeve and the write mine 03a to the pen body 02f to be set. An example of this design is shown in the 7 ,

Depending on the cross section of the pen 01g , as well as the size of the intended magnetic element 06G , it is also possible to have a solution according to 8th use. For this purpose, in a simple way at the second end of the pen 01g the pen body 02g with writing lead 03c provided with a groove, for example by means of milling. In this groove can correspondingly the magnetic element 06G be used. In this respect, a particularly secure attachment of the pen according to the invention 01g both on the front end and alternatively on the side edge of a steel plate possible.

Unless at the end of the pen 01b . 01c the magnetic element is placed, is shown in plan view of the second end of the stylus 01d . 01c according to 9 consequently only the magnetic element 06b . 06c ,

The 10 shows in contrast a magnetic element 06d respectively. 06e which is in the pen body 02d respectively. 02a is embedded. This can be both a solution according to 5 as well as according to 6 be.

A solution with sleeve-shaped magnetic element 06f show the 11 in the plan view of an embodiment as 7 ,

Not at all is the pen of the invention 01 limited to a circular cross-section. Rather, it is also possible to use any other forms. The corresponding example shows the 12 with a hexagon for an embodiment, for example according to 10 ,

Likewise, as in 13 an ellipsoid shows the cross section of the pen body 02 form. For this purpose, a rectangular magnetic element 06 can be used, which is thus the most cost-effective design for a magnet. In longitudinal section, this in turn can be both the shape of 5 or 6 accept.

A top view to the solution 8th show the 14 , Evident is the block-shaped magnetic element 06G which is eccentric to the pen body 02g is used.

In continuation, it is further advantageous to provide a solution according to 15 use. In this case, the pen body becomes 02 slotted at its end across and a block-shaped magnetic element 06 used.

Since the production of a magnetic element 06 leads in the most cost-effective variant to a rectangular, sharp-edged form, it is also advantageous if the pen body 02 on the two sides where the magnetic element from the slotted pen body 02 looks out, matching the dimensions of the magnetic element 06 flattened. For a polygonal pen body 02 this is given in a simple way. For a pen body 06 in Shape of an ellipse sketches the 16 an example of an advantageous flattening with magnetic element 06 ,
