Description

The invention relates to a marking device, in particular for marking, marking or labeling boreholes, cutting edges or bearing lines.

In particular, in the course of a craft activity, it is common to pre-mark a borehole, a cutting or sawing edge or a desired investment line on a component of a construction to bewerkstelligenden, a wall or a ceiling. As a guide to the applied mark usually a ruler or stencil is placed on the object to be marked. Often, as a template directly another part is used, which is to be attached or to be placed on the object to be marked. For example, for attaching a two-piece threaded bore, it is common practice to apply a first portion provided with a prefabricated bore to a second portion to be drilled in the desired attachment position and to pre-mark the bore to be attached through the bore of the first portion on the second portion.

For such a marking work is usually a pen, especially a pencil, pen or fiber pen, used. However, the application of markings by means of a common pen is often associated with handling difficulties. On the one hand, the points to be marked are often difficult to access with a standard pen. This is especially true when a marker is to be attached to the bottom of a slender and deep bore, or a line is to be marked behind a wide spacer edge. An ordinary pen is often too wide for such marking work. On the other hand, a sufficiently thin pin is often not very suitable for such a marking activity due to the lack of robustness, and in particular is subject to rapid wear and a high risk of damage.

From the EP 0 752 932 B1 discloses a writing or drawing implement with a pen and a removable cap. In this case, the cap is provided with a mounting bracket which is struck on the open side of the cap and aligned with its free end in the direction of the closed end of the cap.

A marking device according to the preamble of claim 1 is made US 2006/0018700 A1 known. This marking device comprises a marker pin designed in the manner of a felt or fiber pencil, the fibrous application lead of which is received in a stationary manner in the pin housing.

Out DE 296 14 202 U1 is known a mechanical pencil with a protective cap and an integrated cap sharpener. The protective cap is in this case provided at its upper, facing away from the insertion opening for the pin side with a blind end, in which a through hole is introduced. On the top of the blind end, a cylinder is placed, which represents the actual sharpener, and accordingly contains a blade inclined obliquely to the longitudinal axis of the protective cap. The tip of the lead of the mechanical pencil is thereby advanced through the through hole into the interior of the cylinder. The mechanical pencil is thus sharpened with the protective cap attached, the protective cap serving to center and guide the sharpener with respect to the pencil lead.

Out DE 20 2004 005 040 U1 Furthermore, a sharpener for a cosmetic pencil is known. The sharpener has a sleeve-like sharpener housing which has an open insertion end for insertion of the cosmetic pencil to be sharpened. At the end remote from the insertion end of the sharpener housing, a further sleeve-like housing portion is arranged. This further housing section is separated by an intermediate wall of the sharpener housing and formed in the interior in the manner of a tight blind hole, and serves as a protective cap for the cosmetic pencil.

The invention has for its object to provide a marking device, which is particularly suitable for a marking activity of the above type.

This object is achieved according to the invention by the features of claim 1. Thereafter, the marking device comprises a marking pen and a protective cap for the marking pen. Trained as a mechanical pen marking pen comprises a pin housing and a displaceable Auftragsmine arranged therein, which is displaceably guided in the pin housing by means of an actuating mechanism. The pin housing is divided into a wide grip area and an axially adjoining thin neck area, wherein an outlet opening for the pin lead is formed at the free end of the neck area. The protective cap has an elongated interior opening into a cap opening, which is provided for partially receiving the marking pen. This interior is adapted to the shape of the marking pen. It includes a narrow interior portion for receiving the neck portion, and a wide interior portion for partially receiving the handle portion of the marking pen. On the outer surface of the cap, a mounting bracket is further arranged. This mounting bracket is molded onto the protective cap in an area adjoining the cap opening and from there essentially runs towards the end of the protective cap facing away from the cap opening. There, a sharpener for the order mine is integrated, which here has an insertion opening, wherein a conically tapered lead channel leads.

Marking and marking work is considerably simplified by the marking device described above. Thus, the marking pen is due to its comparatively wide grip area stable and ergonomic design, especially good to grasp. On the other hand, the thin neck region of the marking pen makes it possible to apply a marking even in a location which is difficult to access, through a comparatively deep and narrow bore or behind a wide spacer edge. The design of the marking pen as a mechanical pen, ie in the manner of a printing or automatic pencil, has proven to be particularly practical for marking work, especially since such a pen is virtually no permanent wear due to the interchangeability and adjustability of the order mine, and thus under harsh operating conditions Long marking device can be used without handling disadvantages. The interchangeability of the order mine also allows mines of different consistency depending on their particular suitability for different application areas in exchange with each other. In particular, soft, pasty mines for markings on smooth surfaces, and hard mines for markings on rough surfaces can be used particularly advantageously, without the need for a respective own marking device would be required.

By the protective cap is adapted to the shape of the marking pen and in particular with inserted marker not only the neck area, but also receives a part of the grip area, the marking pen, especially the sensitive neck area thereof, effectively protected against damage.

A special handling simplification is achieved by the attachment of the mounting bracket according to the invention. This allows, namely, to secure the cap as a quiver with the cap opening up to a pocket of the work clothes, and thus in particular on the body. The marker is thereby in a simple manner, in particular one-handed, pulled out of the cap and after use in the (further attached to the work clothes) protective cap zurücksteckbar. This ensures that the marking is tangible at any time, but on the other hand, at any time for the duration of non-use is well protected against damage. The ability to attach the marking device on the body and the simple one-handed operation are of particular importance in a marking activity, especially as here usually a hand for applying and holding a ruler, a template or a part used as a template is needed, and a safe storage option for the marker in range usually does not exist.

In order to prevent the protective cap from being accidentally released from the pocket to which it is attached when the marker pin is withdrawn, at least one blocking element, which acts like a barb on the fabric or the pocket, is formed on the inner surface of the fastening clip. clawed "and thus counteracts accidental withdrawal of the cap. Preferably, the or each locking element is again in the form of a resilient, integrally formed on the mounting bracket bracket. The blocking element comprises in this form a retaining leg, with which it is integrally formed on the inner surface of the mounting bracket, as well as an angled from this holding leg free arm. The holding leg is in this case from the inner surface of the mounting bracket obliquely in the direction of the fixed end of the mounting bracket, while the free arm is in turn aligned obliquely in the direction of the inner surface of the mounting bracket.

In order to keep the or each locking element on the one hand stable on the mounting bracket, and on the other hand to ensure good resilience of the locking element, the retaining leg is suitably designed such that it tapers, starting from the inner surface of the mounting bracket in the direction of the free arm. By the free arm of the or each locking element is formed as a support plate, on the one hand a good holding effect of the or each locking element is achieved, but on the other hand effectively excluded that the work clothes on which the cap is attached, damaged by the blocking element, in particular torn.

A step-like shoulder, preferably provided between the grip area and the neck area of the marking pin, serves, in cooperation with a stop provided in the interior of the protective cap, to limit the insertion path of the marking pin into the protective cap in a well-defined insertion position.

Preferably, the outer diameter of the handle portion of the marking pen on the one hand and the inner diameter of the wide interior portion of the cap on the other hand adapted to each other such that when inserted into the protective cap marking between this and the cap an annular gap is formed. This effectively prevents contaminated or scratched by the adhering to the marking dust grains, the protective cover or the marker is even jammed in the protective cover. The radial strength of the annular gap this amounts to at least 0.2 mm. Preferably, the radial thickness of the annular gap is in a range between 0.3 mm and 0.5 mm, in particular about 0.35 mm.

In this case, the marking pin is preferably held coaxially with the protective cap by a centering projection or a plurality of cooperating centering projections, which rest against the outer circumference of the grip area when the marking pin is inserted. Preferably, the centering projection or at least one of the centering projections is dimensioned such that it acts radially on the inserted marking pin in the grip region and thus holds it captive in the protective cap.

In order to ensure a secure hold of the marking pen in the protective cap, it is preferably provided that in the inserted state at least a third, preferably about 50% to 60% of the axial length of the handle portion of the pin housing is received within the protective cap.

In an advantageous embodiment of the invention, the end facing away from the writing tip of the Markierstifts a pushed onto the handle portion sealing sleeve made of elastic material, in particular rubber or plastic, whose writing tip facing edge is formed into a sealing lip. The sealing sleeve, and in particular its sealing lip, are in this case designed such that the sealing lip in the protective cap plugged marking pen dustproof the cap opening of the cap and preferably also splash-tight, so that penetration of dust or spray into the cap is at least avoided when inserted marker , By the sealing sleeve further handling simplification is advantageously achieved by the remote from the writing tip end of the sealing sleeve is widened to a broad and thus particularly ergonomic Abstützwulst.

In order to be able to sharpen the application lead in a particularly advantageous manner during handling, a sharpener is integrated into the protective cap at the end of the protective cap facing away from the cap opening.

According to the invention, this sharpener has a lead guide channel tapering at least in a section for guiding the application lead, this lead lead channel opening into an insertion opening at the end of the cover facing away from the cover opening. The marker is thus inserted into the tip thereof at the end of the protective cap opposite the cap opening.

The mine guide channel is cut in functional and manufacturing technology simple execution at least in a section laterally to form a discharge slot for mine material, wherein at least one edge of the ejection slot is formed into an integrated cutting edge or scraping edge.

In an advantageous embodiment, the pin housing comprises a base body made of plastic and a cross-sectionally approximately C-shaped jacket which is snapped on the base body in the manner of a clip in the grip area. The jacket consists in equally preferred variants of the marking either metal or a transparent plastic. In metal design, the jacket acts as a particularly effective protection against mechanical damage and thus allows a particularly durable design of the marking. The alternative embodiment of the jacket made of a transparent plastic makes it possible to apply a label visible from the outside on the body, which is effectively protected in the final assembly by the jacket against abrasion.

The jacket is expediently at least substantially fit exactly in a complementary shaped recess of the base body, so that an outer surface of the shell is at least substantially aligned with an axially adjacent outer surface of the body. As a result, edges and depressions on the surface of the marking pen, which would favor the accumulation of dust and other contaminants, largely avoided.

By forming in a further preferred embodiment in the grip area on the circumference of the pin housing at least one knob-like projection is finally prevented in a simple and effective manner that the marking roll rolls out of reach, if it is temporarily stored in use on a sloping surface.

This in Fig. 1 Marking device 1 shown comprises a marking pen 2 (shown in FIG Fig. 1 a) and a (in Fig. 1 b shown) protective cap 3, in which the marking pin 2 can be inserted. The marking pin 2 comprises a pin housing 4, which is preferably at least partially made of plastic. The marking pen 2 further comprises a mandrel 5 in the form of a lead or colored pencil lead or one in the form of a soft pasty lead material, as used for example for wax crayons. In the case of the marking marker 2 shown, it is also possible to use a plurality of application leads 5 with a different consistency in exchange for one another.

The marking pen 2 is designed as a mechanical pen. The order mine 5 is thus slidably received in the pin housing 4 and can by means of a running in a conventional manner actuation mechanism 6, of the in Fig. 1a only one push button 7 is visible, can be adjusted axially. For use, the application mine 5 is advanced in a known manner by means of the actuation mechanism 6 in such a way that it protrudes from the pen housing 4 at an exit opening forming the writing tip 8 of the marking pen 2.

The pin housing 4 is articulated in a relatively wide and substantially cylindrical grip region 9 facing away from the writing tip 8 and a comparatively thin neck region 10 which adjoins the grip region 9 axially with respect to a pin axis 11 and carries the writing tip 8 on the free end.

The neck portion 10 is formed by a conical housing portion 12 and an approximately cylindrical contact portion 13 of the pin housing 4 adjoining the writing tip 8 in the direction of the writing tip 8 Pin housing 4 by a thin, the order mine 5 surrounding protective tube 14, preferably made of metal, extended. The axial length of the neck region 10 is preferably at least 25%, preferably approximately one third of the axial length of the marking pin 2. Between the neck region 10 and the grip region 9, a preferably step-shaped shoulder 15 is formed on the pin housing 4.

The likewise preferably made of plastic protective cap 3 encloses an elongated interior 16, which opens at a longitudinal end 17 in a cap opening 18. The interior 16 has a shape adapted to the shape of the marking pin 2 and thus comprises a narrow interior portion 19 for receiving the neck portion 10 of the marking pin 2, which widens in a transition region 20 in the direction of the cap opening 18 to a wide interior portion 21. The latter is provided for partially receiving the grip area 9 of the marking pen 2. Between the narrow interior portion 19 and the transition region 20 of the interior 16 is narrowed by an annular retaining bead 22. Instead of the annular retaining bead 22 may also be provided a plurality of ring-segment-shaped or knob-like projections.

The interior 16 is formed substantially rotationally symmetrical with respect to a cap axis 23. The protective cap 3 has an outer surface 24 which essentially corresponds to the shape of the inner space 16 and, in particular, continuously widens in a section corresponding to the transition region 20.

The protective cap 3 further comprises an approximately S-shaped curved elastically deflectable mounting bracket 25. The mounting bracket 25 is integrally formed with a fixed end 26 in an adjacent to the cap opening 18 region of the protective cap 3 to the outer surface 24 and extends from there approximately parallel to the cap axis 23rd with a certain distance from the outer surface 24 along the protective cap 3, so that a free end 27 remote from the fixed end 26 of the mounting bracket 25 from the open longitudinal end 17 facing away from the protective cap 3 and an opposite, closed longitudinal end 28 of the protective cap 3 faces.

On an inner surface 29 of the mounting bracket 25, which faces the outer surface 24 of the protective cap 3, the mounting bracket 25 carries two axially offset locking elements 30. In the region of the free end 27, the inner surface 29 is further provided with a retaining cam 31 whose tip substantially the outer surface 24 abuts.

The mounting bracket 25 serves to attach the protective cap 3 to a flat object, in particular to a pocket of a workwear. The locking elements 30 described in more detail below, in particular when the protective cap is attached to a soft, flexible material, such as e.g. Fabric, is attached, after the type of barbs a particularly good backing, which counteracts a removal of the protective cap 3 of the bag. The retaining cam 31 is particularly effective when the protective cap 3 is attached to a comparatively flat, hard object, e.g. a piece of paper or cardboard.

As in particular from the FIGS. 2 and 3 it can be seen, each locking element 30 is formed in the form of a two-legged spring clip. Each locking element 30 is mounted with a retaining leg 32 on the inner surface 29 of the mounting bracket 25, wherein the retaining leg 32, starting from the inner surface 29 obliquely toward the cap opening 18, and thus also in the direction of the fixed end 26, and extends with increasing Distance to the inner surface 29 increasingly tapered. At the end remote from the inner surface 29 of the retaining leg 32, a knee 33 is formed, on which the retaining leg 32 merges into a free arm 34. The free leg 34 is angled by the holding leg 32, preferably at an angle between 60 ° and 100 °, so that its free end 35 is again aligned obliquely in the direction of the inner surface 29. As in particular from Fig. 2 shows the free arm 34 is formed as a comparatively wide support surface, the fabric of a bag or a other soft object to which the cap 3 is attached, opposes a high resistance, without damaging the fabric or object or even tear.

In the interior 16 of the cap 3 are, as in particular in a synopsis of Fig. 1 b and 2 can be seen, three projection-like stops 36 are provided, which cooperate with the paragraph 15 of the marker pin 2, to define the insertion of the marker 2 in the protective cap 3 defined. The stops 36 are each offset by an angle of 120 ° to each other around the circumference of the cap 3. Alternating offset to the stops 36 three centering projections 37 are arranged in the interior 16 continue. These centering projections 37 serve to center the marking pin 2 in the protective cap 3 inserted state with respect to the protective cap 3, so that the pin axis 11 coincides with the cap axis 23.

This insertion position of the marker pin 2 in the protective cap 3 is in Fig. 4 shown. It can be seen in this illustration, in particular, that the centering projections 37 engage in the grip area 9 of the marking pin 2 on its outer circumference. The centering projections 37 are dimensioned such that they act on the handle portion 9 radially with a predetermined holding force, so that the marking pin 2 is held captive in the cap 3. From the illustration according to Fig. 4 Furthermore, it is clear that the outer diameter of the marking pin 2 is selected in the grip area 9 with respect to the inner diameter of the protective cover 3 in the corresponding wide interior section 21 such that an annular gap 38 is formed in the inserted state between the grip area 9 of the marking pin 2 and the protective cover 3. its radial thickness is about 0.35 mm. In this case, it is ensured by the centering projections 37 that the thickness of the annular gap 38 is essentially constant around the circumference of the marking pin 2, so that in particular therefore the marking pin 2 does not bear against the interior wall of the protective cap 3. Due to the annular gap 38, the marking pen 2 is prevented from being jammed in the protective cap 3 by dust grains which adhere to the grip area 9. By the essentially non-contact Storage of Markierstifts 2 in the cap 3 is also largely avoided that dust or other contaminants from the handle portion 9 of the marking pin 2 on the Innenraurnwand the protective cap 3 are rubbed, whereby the protective cap 3 would dirty successively under dirty environmental conditions.

In the Fig. 4 illustrated insertion position of the pin 2 with respect to the protective cap 3 is defined in particular by the fact that the shoulder 15 of the pin housing 4 abuts against the corresponding stops 36 of the protective cap 3.

In the Fig. 5 is shown in side view a variant of the marking pen 2. Fig. 6 shows a cross section through this marking pin 2 at the level of the handle portion 9, wherein for simplicity in this cross section, only the (empty) pin housing 4 is shown. In contrast, the order mine 5 and the actuating mechanism 6 held therein are omitted in this illustration. In the in Fig. 5 illustrated variant, the pin housing 4 comprises a one-piece base body 40 made of plastic, which comprises the handle portion 9, the conical housing portion 12 and the abutment portion 13. Notwithstanding the above-described embodiment of the marking pin 2, a shell 41 made of metal, in particular stainless steel, or a transparent plastic is applied to this base body 40, which surrounds the base body 40 on the outside in a large part of the grip area 9. The jacket 41 has approximately the shape of a letter C in cross section and is clipped onto the base body 40 like a clip. In this case, the jacket 41 fits snugly into a recess 42 of the base body 40 which is formed integrally with the jacket 41, so that it terminates approximately flush with the base body 40 on the outside.

In the variant of the marker 2 according to FIGS. 5 and 6 are additionally formed on the pin housing 4 in the handle portion 9 two knob-like projections 43. The projections 43 are sufficiently pronounced and arranged sufficiently close to the center of gravity of the marking pin 2, that a rolling of the on a slightly inclined Pad deposited marker pin 2 by each of the projections 43 is prevented.

The in the FIGS. 5 and 6 shown marking pin 2 otherwise corresponds to the embodiment described above.

In the FIGS. 7 and 8 a variant of the marking device 1 is shown, in which on the side facing away from the writing tip 8 longitudinal end 50 of the marking pin 2, a sealing sleeve 51 is pushed, in particular pressed. The sealing sleeve 51 consists of an elastic plastic or rubber.

At the writing tip 8 facing edge of the sealing sleeve 51, a sealing lip 52 is formed. The sealing sleeve 51, and in particular the sealing lip 52, are in this case dimensioned such that in the in Fig. 7 shown insertion position of the marking pin 2 in the cap 3, the sealing lip 52 rests on the edge of the cap opening 18 under pretension, so that the cap opening 18 is sealed when inserted into the protective cap 3 marking pin 2 against ingress of dust and spray. The longitudinal end 50 of the marking pin 2 facing the end of the sealing sleeve 51 is preferably widened to a Abstützwulst 53 or support head, which improves the ergonomics, and thus the handling of the marking pen 2.

In one in the FIGS. 9 and 10 shown embodiment of the protective cap 3 is in the longitudinal end 28, a sharpener 60 for sharpening the Auftragsmine 5 integrated. The sharpener 60 is essentially formed by a bore parallel to the cap axis 23, which acts as a lead guide channel 61. This lead guide channel 61 opens at the longitudinal end 28 in an insertion opening 62 and tapers in the interior, so that it forms a counter-shape for the lead tip to be formed. The lead guide channel 61 can - depending on the desired mine form - inside expire either pointed or in a defined rounding. The lead guide channel 61 is cut open to one side of the protective cap 3, so that an ejection slot 63 is formed for peeled refuse mass. Both edges 64 of this ejection slot 63 are sharp-edged and thus act as a scraping edge for removing the lead mass during the sharpening process. In order to achieve a particularly good scraper effect, edges 64 are formed in particular at an acute angle.

An in Fig. 11 shown variant of the protective cap according to FIGS. 9 and 10 differs from the local design in that the ejection slot 63 does not extend over the entire length of the lead guide channel 61. Rather, according to Fig. 11 the lead guide channel 61 cut open only in one of the lead tip corresponding inner region, so that the ejection slot 63 assumes a window-like contour. In this embodiment, moreover, only the edge 63 lying in the illustration is designed as a scraping edge. To stabilize this edge in this case a metal plate 65 is inserted in the region of the sharpener 60 in the protective cap 3, so that its inner edge flanking the edge 63 at least partially and thus forms the scraping edge.
