Description

  The present invention relates to an operating tool according to claim 1 having a main axis substantially determined by an elongated area (elongate portion) of the tool, and in particular to a writing instrument according to claim 13.

  As the above-described operation tools, particularly writing tools, for example, those in the form of a writing pen are known. They usually have an elongated area and often have a round, oval or at least polygonal cross-sectional shape. When known operation tools, especially writing tools, are used, they are often placed on the surface of a desk or the like between each use (each writing operation in the case of a writing pen). Is used again from the surface when used. In particular, in the case of a writing instrument with a round cross-section, an operation tool is known that uses a clip or a rolling element intended to prevent rolling and prevents the tool from rolling in an uncontrolled state. Thereby, the placed operation tool (particularly the writing tool) remains in the position where it is placed.

  However, a disadvantage of the known operating tools is that it is difficult to pick them up. Such operating tools often have a very narrow or small cross-section, and the surface of the operating tool measured from the surface on which the tool is placed relative to the belly of the finger of the person holding the tool (i.e., the tool can be gripped). In most cases, the height of the surface is smaller than the average height of the belly of the finger, so that it is difficult to grasp the placed operation tool. As used herein, the term “finger belly height” refers to the sense of the terminal sensation at the inner end of each finger relative to the fingertip or to the surface on which the device is placed and supports the same fingertip. The distance between the centers of a terminal sensing ball.

  In particular, when using a plurality of operation tools in the form of writing tools such as colored pencils and color pens, they may be placed in an open state, i.e. without using a protective cap on the individual tip. Many. When these pens or pencils are picked up from the surface on which they are placed, it is easy for unprotected tips to come into contact with the surface. On the one hand, the surface on which the tool is placed is soiled with a pen or pencil, and on the other hand, in the case of a particularly delicate nib, the nib is damaged or damaged by a mechanical load when contacting the surface. There is a disadvantage that it can be destroyed.

  Accordingly, it is an object of the present invention to improve or at least reduce one of the aforementioned disadvantages. Specifically, an object of the present invention is to provide an operating tool that can be quickly, easily and firmly picked up from the surface on which the operating tool is placed.

  The solution according to the invention provides an operating tool having the features of claim 1 and a pen or pencil having the features of claim 13. Advantageous configurations and developments are set forth in the individual claims of the appended claims.

  An operating tool, in particular a writing tool, having a main axis substantially determined by the elongated range of the tool according to the present invention, has at least one active end and at least one passive end. The passive end has at least one manually actuable lifting aid for lifting the active end.

  The lifting assist portion (preferably, the region of the lifting assist portion constituting the end portion of the writing instrument) is integrated with an anti-rolling portion of the operating tool that is advantageous for preventing rolling motion around the main axis of the operating tool. ing. In other words, this integrated rolling stop will slow down the progression of the rolling motion that has started and will normally stop when the writing instrument is placed on a surface that does not extend horizontally. .

  In the operation tool used for the writing tool, the active end portion is configured by an end portion on which the core of the writing tool is provided. Accordingly, the passive end portion is the end portion on the side opposite to the tip of the writing instrument. By providing a manually actuable lifting aid at the passive end of the operating tool, the user of the operating tool according to the invention can easily, simply and quickly use the manually actuated lifting aid. In this case, there is a risk of adversely affecting the core tip at the active end of the operation tool, or contaminating the surface on which the operation tool is placed with the tip of the operation tool. Absent.

  An additional advantage is provided that the anti-rolling part integrated in the lifting aid or in the region of the lifting aid prevents, for example, the operation tool placed on an inclined surface from rolling. The

  The lifting aid of the operating tool according to the invention can be provided at the passive end of the operating tool, in particular in the form of a surface substantially inclined with respect to the main axis of the operating tool.

  The anti-rolling part is preferably integrated in the region of the lifting aid that constitutes the passive end of the writing instrument and extends substantially perpendicular to the main axis of the operating tool (in certain configurations it intersects the main axis) It is particularly preferred that it is in the form of a substantially protruding portion that protrudes beyond the periphery of the (terminal) edge. In other words, a part of the lifting assist portion (for example, a portion where the end portion extends) protrudes beyond the periphery of the operation tool or outward on at least one side. That is, in order to constitute the rolling stop portion, the length of the edge portion is larger than the maximum diameter of the operation tool without the lifting auxiliary portion.

  This arrangement is one possible way of providing the operating tool with a manually actuable lifting aid according to the invention. The sloped surface of the lifting aid that can be actuated by hand functions as a lever and when actuated, the contact point between the operating tool and the support surface (the contact point is tilted away from the passive end of the operating tool) The active end of the operating tool can be lifted by the fact that the predetermined end by the end of the surface acts as a fulcrum (ie, pivot or support) for the insulator. In other words, the lifting motion occurs substantially by using the law of lions, and the pivot point is provided in the region between the lifting end at the passive end and the active end, The movement of the part causes a corresponding movement of the active end. The lifting height can be defined or adjusted by the relationship between the length of the lever arm or the position of the pivot point. When the lengths of the lever arms on both sides are the same, the lifting height is equal to the moving distance of the lifting assist portion. In order to produce a quick lifting action or to provide a quick grip, a lever ratio in which the lifting aid travels less than or significantly less than the lifting height is particularly advantageous. Thus, a sufficient lifting height can be quickly achieved by a short distance movement on the lifting assist side. In particular, an insulator ratio of 1: 5 and higher (ie, for example, the insulator arm on the passive end side is 1 cm and the insulator arm on the active end side is 5 cm) is advantageous. It should be noted that at least the passive ends, and in particular the lifting aids arranged there, should have a rigid construction with respect to bending so as to enable the desired lever function on the lifting aid side.

  In the lifting operation, the user of the operating tool according to the present invention operates the lifting assistant by pressing the lifting assistant at the passive end of the operating tool with one or more fingers, thereby causing the inclined surface to The inclined surface and the surface on which the operation tool is placed are moved to an end position where they are substantially parallel. In this case, the operation tool is inclined around the contact point between the operation tool and the surface. This contact point is predetermined by the end of the inclined surface that is inside the tool (or the inner end in relation to the tool). This tilting motion is a rotational motion about the contact point, and the active end is lifted in a manner corresponding to the length ratio of the lever arms. The lift height can be calculated as the sine of the angle change x the distance from the contact point to the active end. Thus, at the end of the lifting operation, the active end of the operating tool is in the air at a predetermined distance from the support surface. That is, the active end of the operating tool is spaced from the support surface, and a male or female user of the operating tool according to the present invention grasps or picks up the operating tool much more easily than when the tool is placed on the support surface. be able to. Therefore, in the example where the lever arm ratio is 1: 5, the lifting height is 5 cm when the moving distance of the lifting assist portion is 1 cm, for example.

  In one specific configuration, the operating tool according to the present invention has a passive end configured substantially similar to the end of the tube. Tubular configurations are known, for example, from German Utility Model 1938045 or German Utility Model 7911160. However, in these cases, the entire body is in the form of a tube. However, the material of the lifting aid and preferably the material of the operating tool is preferably rigid or nearly inelastic with respect to bending, unlike known tubular bodies. Specifically, the shape of such a tubular passive end has two surfaces on opposite sides that are substantially inclined with respect to the main axis of the operating tool.

  In the specific embodiment described above, the anti-rolling portion is provided in the region of the lifting auxiliary portion that constitutes the passive end portion of the writing instrument, and by an edge disposed at a predetermined angle with respect to the main axis of the operating tool. It can be particularly well integrated. The angle is preferably 90 °. That is, the edge is disposed perpendicular to the main axis, and in a particularly preferred configuration, the edge intersects the main axis at a right angle. According to this preferred development, the length of the edge is larger than the diameter of the operating tool in the area away from the lifting aid, and the desired anti-rolling portion (ie, anti-rolling function) is integrated into the lifting aid. . For the anti-rolling function, it is essential that the edge protrudes beyond the periphery of the operating tool on at least one side.

  Such a lifting aid in the form of a tube with two inclined surfaces is intended to rotate the lifting aid to a particularly preferred position with respect to the lifting procedure when placing or picking up the operating tool according to the invention. Has the additional advantage of not having to. When providing a lifting aid in the form of a tube, two such particularly preferred mounting options have already been provided if the ends having a tubular configuration are symmetrical in nature. These two mounting options are individually displaced by 180 ° relative to each other with respect to the longitudinal axis of the generally elongate operating tool, and even in situations where the operating tool is placed in a non-perfectly oriented relationship. Therefore, the configuration described above with respect to the operating tool according to the present invention is practically irrelevant to the situation in which the operating tool is placed on the support surface, and the operating tool is lifted and gripped by the lifting aid according to the present invention. Provides the advantage of being able to.

  The operating tool according to the invention is such that when the lifting aid is actuated, the active end of the operating tool is lifted to at least a predetermined lifting height, and the lifting height achieved is the average of a person's finger belly. It may have a configuration such that it is equal to or higher than the height of the belly of the finger constituted by the height. As used herein, the term “finger belly height” refers to the sense of the terminal sensation at the inner end of each finger relative to the fingertip or to the surface on which the device is placed and supports the same fingertip. The distance between the centers of a bulge. The lifting aid according to the invention is particularly preferably adjusted so that the lifting height is greater than 10 mm when actuated.

  In order to ensure that the operating tool can be easily gripped in the raised state, the minimum height at which the active end of the operating tool must be lifted can be defined as described above. In other words, one advantageous configuration is such that the lifting height achieved when the lifting aid is activated is designed directly to the average height of the average user's finger belly. To. As a result, the finger used to hold the tool can be supported by the fingertip that is in contact with the surface on which the tool is placed, and the grip of the finger makes the finger belly automatically and the optimal tool. Since the contact can be made in a state, the procedure related to the gripping of the placed operation tool is particularly simple and firm. Furthermore, a sufficient lifting height is ensured so that the operating tool can be gripped correctly (which is much more difficult if the lifting height is smaller than the height of the belly of the finger). In such a case, the operation tool has a tendency to slide down from the finger and return to the surface on which it was placed when it is grasped. In selecting an exact value for the lifting height that can be predetermined in this way, this value is adapted to the skill of the intended user (eg a trained graphic designer, not a small child) Further, it can be particularly adapted to the average height of the finger pads of individual user groups. In that way, the operating tool according to the invention can be better individualized in relation to the intended user group.

  The operating tool has a body provided between the passive end and the active end. The body may specifically have a main cross-sectional shape that is substantially polygonal, triangular or round. In the region of the lifting aid, this main cross-sectional shape can be integrated into the functionally controlled cross-sectional shape of the lifting aid, preferably flowing (i.e. without producing a step or the like). In this regard, when the lifting aid is actuated, the anti-rolling part integrated with the lifting aid restricts the rolling or rotation around the main axis of the operating tool, and the lifting assist is restricted as it approaches the end position. It may be advantageous to increase the.

  The operating tool according to the invention, or at least the lifting aid according to the invention, is preferably made of a material which is substantially rigid with respect to bending, in particular plastics, metals or alloys. Particularly when made of plastic, a great advantage is provided with regard to the cost efficiency of the production of the operating tool according to the invention. In addition, the preferred configuration of rigidity with respect to this bend is that the lifting movement of the lifting aid is not necessary in view of the desired lifting height of the active end of the operating tool, so long as it is not necessary to consider or compensate for the elasticity of the operating tool. And makes it possible to simplify the structural construction. Rather, the rigid configuration of the operating tool with respect to bending provides a substantially complete lever system between the lifting aid and the active end of the operating tool.

  The operation tool according to the present invention can be easily and inexpensively manufactured by, for example, an extrusion blow molding method or an injection molding method. Extrusion blow molding has the great advantage that, among other things, it can be manufactured at a reduced cost, in this case especially when manufacturing lifting aids in the form of tube ends in the extrusion blow molding process. In addition, the passive end of the operating tool is already closed like a fold at the bottom of the tube (ie, similar to the configuration of the fold at the bottom of the tube). Thus, especially with respect to writing instruments, there is no longer a need for further steps to fix and seal the bottom of the passive end of the operating tool.

  The writing tool as the operating tool according to the present invention may substantially comprise a writing tool body which is preferably hollow so that a cavity for receiving the storage element of the writing liquid can be provided inside the operating tool. Such a storage element is fully functional only if the contact and spacing to a writing member having a nib disposed essentially at the active end of the operating tool is kept substantially constant. In particular, in a storage element having a capillary action (for example, a pad-like storage means) and a writing member having a capillary action (such as a fiber rod), when the storage element is emptied during writing, it is passively followed. It is important to be able to introduce air from the end into the storage means. In other words, the supply of air to the end of the containment element at the passive end of the device should never be interrupted or interrupted, for example, by a lateral constriction in the cavity that receives the containment element. Absent.

  By providing a lifting aid at the passive end of the operating tool, the cavity of the operating tool at the passive end is altered (specifically reduced). Therefore, a stopper or a contact portion can be provided in the vicinity of the passive end portion (at least inside the operation tool). At this time, the stopper or the abutting portion holds the storage element at a predetermined interval in the axial mobility in the direction associated with the passive end, and the stopper or the abutting portion is the entire end surface of the storage element. Comply with requirements including not extending over (ie, narrower than the diameter of the containment element at the passive end). This substantially ensures the axial fixation of the storage element in the cavity of the operating tool, which on the one hand ensures the contact between the writing member and the storage element at the active end, and It prevents the supply of air from being unintentionally squeezed or closed at the end of the containment element at the passive end of the device. In this regard, the design configuration of the lifting aid with this integrated anti-roller has the advantage that the ventilation of the storage element at the rear end is improved via a cavity in at least one corner of the tube configuration. I will provide a.

  According to the present invention, the operating tool may have a configuration in which the passive end of the operating tool is substantially completely constituted by the lifting assist part. This embodiment is also useful for a more universal use of the operating tool according to the present invention. Since the entire passive end is in the form of a lifting aid, the level of accuracy required on the user side to perform the lifting action and to grasp the operating tool is reduced.

  In the operation tool according to the present invention, the lifting assisting portion is substantially used, and the passive end portion simultaneously serves as a gripping assisting portion for a plurality of operation tools (specifically, flat, that is, almost human fingers). It may be further advantageous to design an area with an average diameter of the abdomen and a region where the material thickness is at most twice the wall thickness of the operating tool. This generally flat configuration of the lifting aid provides further utility to the user of the device according to the invention. The user can grasp and move the plurality of pens at a time in both the open state and the closed state by grasping the lifting assist portions of the plurality of operation tools placed in a substantially coincident relationship. In particular, such movement can be performed by simply grasping with two fingers. On the other hand, in the case of a known operation tool, in order to move two or more pens, it is usually necessary to have a plurality of pens in the entire hand.

  In the case of a hollow configuration, the wall thickness of the wall of the operating tool should be kept substantially constant in order to ensure that the bending stiffness of the operating tool according to the invention is substantially the same over the entire elongated range. Can be advantageous. If the wall thickness is constant, the operating tool according to the invention can also be produced much more advantageously, for example using an extrusion blow molding process, so that it also has advantages in terms of the manufacturing process.

  Furthermore, the operating tool according to the invention can have an advantageous configuration if it has at least two layers of walls in at least a partial area (ie the walls are composed of at least two layers of material). Such a double wall is particularly advantageous when the requirements to be fulfilled outside the operating tool in at least a partial area differ from the situation in at least a partial area inside the operating tool. For example, when handling aggressive fluids that may be contained within the operating tool, the double wall configuration of the operating tool may also serve to provide a shield against those fluids. As a result, even more highly corrosive fluid can be provided inside the operation tool.

  In particular, it is advantageous to employ a material for the inner wall that ensures a low diffusion rate. Polypropylene (PP), for example, has proven to be particularly suitable because of its very low water vapor permeability, so that the operating tool can enjoy a particularly long service life.

  Further, the operation tool has at least a two-layer wall structure, and at least a partial region of the outer layer or the material layer portion (for example, a region of the lifting assist portion and / or a region where the operation tool is intuitively preferably picked up) is prevented from slipping. Advantageously in the form of a coating. Such a non-slip coating serves to provide a further improvement in the usefulness of the operating tool according to the invention. By the anti-slip coating, the lifting operation itself can be performed more easily, and after the lifting operation, the operation tool can be gripped more easily.

  A further subject matter of the invention is a pen having the features of the operating tool according to the invention described above. Such pens have significant advantages over known pens and writing instruments. Indeed, in the case of color pens and pencils used for graphic coloring, it is possible to work with multiple pens and pencils of different colors with different core shapes (for example, different writing widths and strengths). Yes, these pens and pencils are, for the most part, placed on the surface in an open state (i.e. without the use of a closure cap) and sometimes on a graphic to be colored. The provision of an operating tool in the form of a pen according to the invention makes it possible to pick up and grip the pen more quickly on the one hand with respect to such working conditions, thereby increasing the working speed and on the other hand lifting the tool. In particular, the surface on which the tool is placed (especially the graphic to be processed) can be prevented from becoming dirty. Indeed, undesired smudges on the graphic being worked on will adversely affect or destroy the desired result of the work (ie the graphic). Thus, the pen in the form of an operating tool according to the present invention not only facilitates the user's work, but at the same time protects the result of the user's work.

  In the case of the pen according to the invention, a storage element can be provided for the writing liquid, for example in the form of a pad-shaped storage means having a capillary action. Such a pad-shaped storage means having capillary action serves to store a large amount of fluid, for example color ink, and is at the active end of the pen via a writing member (for example a fiber rod). The fluid can be discharged in a controlled manner to a core (for example, a fiber core).

  In particular in the case of writing pens, it may be advantageous to provide a gripping surface on the operating tool, in addition to or as an alternative to providing an anti-slip coating in at least a partial area of the pen. Such a gripping surface may serve, for example, to allow the writing pen, drawing pen and / or marker pen to be held and guided more easily and ergonomically during the drawing operation. In addition, to make the lifting operation easier and ergonomic, in addition or as an alternative, such a gripping surface is also provided at the passive end (specifically in the area of the pen lifting aid). Can do. Such gripping surfaces can be designed in various ways (e.g. in the form of grooves, recesses or outwardly protruding bumps). Note that the present invention is not limited to individual configurations of such surfaces.

  In one specific configuration, the closure cap for the active end of the operating tool has a further lifting aid, or the operating tool is provided with a single lifting aid. In the former case, the device can be lifted from both sides (ie, the active and passive ends) in the closed state. It is further advantageous if the cap is adapted to fit in place on the passive end with or without the lifting aid. By reversibly fixing the closure cap to the passive end, there is no risk of losing the cap during use and the cap can be stored safely. Therefore, by providing a lifting aid on the closure cap, in any possible variation of the state fitted to the tool (especially when the closure cap hides the lifting aid already present at the passive end). The lifting operation according to the invention can be performed. The operating tool according to the present invention has all possible situations (i.e. the state in which the closure cap is in the active end, the state in which the closure cap is in the passive end, and the lifting aid, even without the closure cap). In the passive end), it can be lifted with the method according to the invention. According to the present invention, the above-mentioned closing cap having the lifting assisting portion according to the present invention can be provided with or integrated with a rolling stopper.

  Further advantageous configurations of the invention and a number of exemplary embodiments of the invention will now be described in detail with reference to the accompanying drawings. The terms “left”, “right”, “upper”, and “lower” as used in the description of the specific embodiments relate to drawings that are oriented so that the reference and drawing identification numbers can be commonly read.

Side view of yet another embodiment of an operating tool according to the present invention in the rested state The figure which shows the operation tool of FIG. 2a in the state of being lifted Sectional view at the passive end of yet another embodiment of an operating tool according to the present invention. The figure which shows the two operation tools by this invention of FIG. 2 in the state hold | gripped with two fingers. An oblique view of yet another embodiment of an operating tool according to the present invention.

1a and 1b show isometric views of the operating tool 10, respectively. The operating tools 10-1 and 10-2 of each embodiment shown in FIGS. 1a and 1b have a main axis 1 that is substantially determined by the elongated range of the operating tools 10-1 and 10-2, respectively. The lower left end has an active end 12 and the upper right end has a passive end 14. A tip 12 ^* is found at each of the active ends 12 of the operating tools 10-1 and 10-2.

  In the present specification, the lifting assisting portion according to the present invention is described as a writing tool as an example of an operating tool, but is not limited to application to a writing tool. With regard to writing instruments, the lifting aid according to the invention can be used for practically all possible writing instruments, and in this respect cartridge-type writing instruments, sign pens, felt-tip pens, pencils etc. may be mentioned. These are not exhaustive.

The embodiment of FIGS. 1a and 1b shows an operating tool 10 in the form of a ballpoint pen as a writing pen, respectively, and a refill cartridge, which has long been known to have a ball as the tip 12 ^* , is made of plastic material. It is arranged in a casing 16 composed of two parts. A plurality of groove-shaped recesses are provided as gripping surfaces 15 in the front portion 16 a of the casing 16 in the vicinity of the active end portion 12 of the operation tool 10. During the writing operation, the operation tool 10 can be guided ergonomically and firmly on these gripping surfaces 15. The holding surface 15 also serves as an assist when holding the operation tool 10 in a state where the operation tool 10 is lifted.

  The individual lifting aids 20-1 and 20-2 are respectively provided at the passive ends 14 of the operating tools 10-1 and 10-2 having the grip 16 b of the casing 16. The lifting assist portions 20-1 and 20-2 have inclined surfaces 24 that extend substantially inclined with respect to the longitudinal axis of the operation tools 10-1 and 10-2. In the case of the operation tools 10-1 and 10-2 of the embodiment of FIGS. 1a and 1b, the lifting assisting portions 20-1 and 20-2 and the gripping portion 16b have an integral configuration. That is, the lifting assist part is integrated with the gripping part 16b. Note that the lifting assisting portions 20-1 and 20-2 can be attached to the gripping portion 16b as individual components when different materials are used, for example. Lifting aids 20-1 and 20-2 constitute a passive end 14 and thus constitute a closing end at the rear of the operating tools 10-1 and 10-2.

  When a male or female user wishes to pick up or pick up the operating tool 10-1 or 10-2 according to the embodiments of FIGS. 1a and 1b placed on a support surface, the user must at least 1 It is only necessary to push the lifting aids 20-1 and 20-2 with a finger so that the inclined surface 24 moves in the direction of the support surface on which the tool is placed. Due to this pressure, the operation tools 10-1 and 10-2 are tilted around the rotation axis D extending through the end 25 of the inclined surface 24 connected to the gripping portion 16b, and the operation tools 10-1 and 10-2 are tilted. Active end 12 of the In particular, the region provided with the gripping surface 15 of the operation tools 10-1 and 10-2 is completely lifted from the support surface in that state, and can be easily grasped.

  The configuration of the operation tool 10-2 shown in FIG. 1b is that the rolling stop portion is further integrated with the operation tool 10-2 (specifically, the lifting auxiliary portion 20-2). This is different from the configuration of the operation tool 10-1. In other words, this specific configuration of the passive end 14 simultaneously provides the additional advantage of an anti-rolling part in addition to the advantageous lifting aid 20-2, so that a tilted or inclined surface is provided. It is effectively prevented that the operation tool placed on the rolls. For this purpose, the edge 62, which is configured as a folding part at the bottom of the tube, which constitutes the end of the lifting aid 20-2 and the operating tool 10-2, is at least one end 64- of the edge. 1 and 64-2 have a design that projects beyond the remainder of the width of the operating tool. In other words, the length of the edge portion 62 is larger than the diameter of the portion constituted by the active end portion 12 and the grip portion 16a of the operation tool 10-2. Thus, the embodiment of the operating tool 10-2 shown in FIG. 1b protrudes or protrudes from both sides of the lifting aid 20-2 beyond the periphery of the rest of the operating tool (ie As the edge 62 (to constitute), there are two anti-rolling parts 64-1 and 64-2.

Figures 2a and 2b show two states relating to the lifting operation of a further embodiment of the operating tool 10 ^* . Figure 2a shows the operation in a state of being placed on the surface equipment 10 ^* shows the operation tool 10 ^* in Fig. 2a in a state in which FIG. 2b is lifted.

The operating tool 10 ^* of FIGS. 2a and 2b relates to a writing tool, the front part 16a having a writing insert with an active end 12 having a core 12 ^* in the form of a fiber rod with capillary action. Have The front part is connected to the gripping part 16b and terminates the gripping part 16b. The holding part 16b has a cavity (not shown), and a writing liquid storage means is provided in the cavity. In the writing operation, the writing liquid is passed from the writing liquid storage means to the core by a fiber rod having a capillary action. Such a pen 12 ^* is particularly sensitive to mechanical forces acting on it.

The operating tool 10 ^* shown in FIGS. 2a and 2b rests on the surface F on which it is placed, and the passive end 14 has a lifting aid 20 in a generally tubular configuration according to the invention. Have. The lifting aid 20 in the form of an end of the tube has two generally inclined surfaces 24a, 24b that are displaced from each other by 180 ° with respect to the longitudinal axis of the operating tool 10 ^* . In this case, one of the two inclined surfaces, 24b, faces the surface F.

If the user wishes to move the operating tool 10 ^* placed from the position shown in FIG. 2a to the lifted position shown in FIG. The upper inclined surface 24 (i.e. the inclined surface facing away from the surface F) is pushed with at least one finger so that the passive end 14 of the operating tool 10 ^* is directed in the direction of the surface F. Push. In this situation, the operation tool 10 ^* is tilted about the rotation axis D at a position where the lower inclined surface 24b is connected to the gripping portion 16b. In the case of the operating tool 10 ^* shown in FIG. 2b, this action occurs as soon as the lower inclined surface 24 (ie the surface facing the surface F) abuts its most exposed position. At the end, in this state, the end portion such as the folded portion at the bottom of the tube of the lifting assisting portion 20 is in contact with the surface F. In this situation, the active end 12 of the operating tool 10 ^* is fully or fully raised. In this lifted state, the active end 12 of the operating tool 10 ^* is lifted from the surface F by a predetermined height A. In the lifting operation, the operation tool 10 ^* rotates around the rotation axis D extending through the contact point with the surface F of the operation tool 10 ^* at the end of the inclined surface 24b, which is the inner end in relation to the tool. Lean on. By this rotation about the rotation axis D, the active end is lifted according to the length ratio of the lever arm. The lift height A can be calculated as the sine of the change in angle α × the distance from the contact point to the active end (ie, A = sin α · L).

The two inclined surfaces 24a, 24b of the lifting aid 20 of the operating tool 10 ^* shown in FIGS. 2a and 2b are substantially symmetrical with each other. Thereby, both the inclined surfaces 24a and 24b can produce the same lifting movement, and can give the same lifting height A. Therefore, the functionality of the operating tool 10 ^* shown in FIGS. 2a and 2b does not depend on the exact position of the operating tool 10 ^{* on} the surface F on which the operating tool 10 ^* is placed. Even in the situation where the operating tool 10 ^* is rotated and placed around the vertical axis, when pressure is applied to the exposed inclined surface 24a of the lifting assisting portion 20 with at least one finger, the lower side is at the latest. When the inclined surface 24b contacts the surface F, the operating tool 10 ^* is automatically oriented and rotated about the vertical axis of the operating tool 10 ^{* to} the position shown in FIG. The result of a lifting operation. In the structure having the anti-rolling part integrated with the lifting assist part, the anti-rolling part always places the operation tool placed in an optimum position for use of the lifting auxiliary part, and an unfavorable position in this regard is almost a problem. It also provides the additional advantage of not being.

In FIG. 2b, the lifting height A is about 18 mm, at which it is possible to easily grasp the round operating tool 10 ^* in the vicinity of the active end 12 with a typical finger size on the user side. it can.

It can have the vicinity of the part 12. Once these fingers are placed around the tool, the operating tool 10 ^* is lifted in the vicinity of the active end 12, and at the same time the pressure load by the little finger on the upper inclined surface 24a of the lifting aid 20 is released, The little finger can be released. Thereby, the operating tool 10 ^* according to the present invention can be lifted with one hand.

FIG. 3 shows a further embodiment of the operating tool 10 ^{** in} a longitudinal section through the passive end 14. The gripping portion 16b of the operation tool 10 ^{** in} FIG. 3 is hollow and has a storage element 30 therein. This storage element 30 is in the form of a pad element with capillary action, in which ink for the tip (not shown in FIG. 3) at the active end 12 of the operating tool 10 ^** is contained. There is. To define the axial position of the storage element 30 with respect to the longitudinal axis of the operation tool 10 ^**, a stopper 32 is provided in the passive end 14 of the operation tool 10 ^**. Stopper may be made in the process, such as for example extrusion blow molding process for manufacturing the operation tool 10 ^** can be in the form of a protrusion that protrudes into the operation tool 10 ^** of the internal space 34. The storage element 30 is supported in contact with the protruding portion that functions as the stopper 32, and is thereby fixed in its axial position. Thereby, on one hand, the pad element serving as the storage element 30 is fixed to a portion of the inner space 34 that is narrowed or tapered toward the end of the tubular configuration, whereby the operation tool 10 is provided. ^** It is prevented from being pushed to the passive end region of ^** while the stopper 32 does not cover the entire rear end face of the storage element 30 so that the ventilation of the storage element 30 at the rear end is particularly good. Secured. In this case, the stopper 32 extends so as to cover only a part of the wall of the operation tool 10 ^** so as not to cause structural limitations on the lifting assisting portion 20.

Furthermore, it can be seen from FIG. 3 that in this embodiment of the operating tool 10 ^** , the wall thickness of the hollow operating tool is selected to be substantially constant. This constant wall thickness, on the one hand, in conjunction with material selection, ensures that the operating tool is sufficiently rigid with respect to bending, and on the other hand, the internal space 34 (especially the storage element 30) is protected from external influences. It is to make it. Further, the constant wall thickness facilitates the manufacture of the operation tool 10 ^** by the extrusion blow molding method.

The passive end 14 has a lifting aid 20 having a substantially inclined surface 24 ^* . The inclined surface 24 ^* of the embodiment of the operating tool 10 ^** has a slightly curved configuration, and the fulcrum of the lever (that is, the lever point or the pivot point) is lifted during the lifting operation. It moves in the direction of the end 24 ^* on the right hand side of the. Therefore, the lifting height A of the lifting assist portion 20 is further optimized (ie, increased).

Further, as shown in FIG. 3, the wall 40 of the operating tool 10 ^** is provided at least partially with two material layers 42,44. In this configuration, the outer material layer 44 of the operating tool 10 ^** is in the form of a non-slip coating. Due to the nature of the slip of the outer material layer 44, when the grab during and around the lifting operation tool 10 ^**, and during the writing operation, it is possible to more easily grasp the operation tool 10 ^**. The outer material layer 44 is made of a plastic material and has already been made in an extrusion blow molding process in the form of a two-component extrusion, and in particular has a high coefficient of static friction in interaction with the user's finger contact. Furthermore, in addition to the technical advantages of the operating tool 10 ^** due to the outer material layer 44, the outer material layer 44 is provided with a material that provides a soft grip to the user in order to provide a feeling of comfort during use. Is selected.

FIG. 4 shows a further alternative embodiment of the lifting aid 20 according to the invention, for example in the operating tool 10 ^* shown in FIGS. 2a and 2b. FIG. 4 shows two operation tools 10 ^* . At the upper end of the two operation tool 10 ^*, two operation tool 10 ^* of the respective raising assist unit 20 hands 50 are gripped by the forefinger 51 and thumb 52 have been depicted. With these two fingers 51 and 52, two or more operation tools 10 ^* can be lifted simultaneously. The two fingers 51, 52 are arranged like a clamp grip so that the two operation tools 10 ^* are oriented in a fan-shaped configuration like a upside-down bouquet below the fingers 51, 52. The lifting aid 20 is gripped and pressed against each other. When three or more operation tools are picked up in such a manner, the fingers 51 and 52 are in contact with only two operation tools located outside. If the lifting assisting portion 20 has such a design configuration, more operating tools 10 ^{* according} to the present invention can be held in a more comprehensive manner.

FIG. 5 shows a further embodiment of the operating tool 10 ^*** according to the invention. The active end 12 is not yet provided with a writing insert with a writing member having a nib, so FIG. 5 shows the state of a semi-finished product (ie in the case of a pen as an operating tool, for example). Shows the operation tool 10 ^*** before the writing liquid storage means for transferring the writing medium to the writing support section and the writing insertion part are finally assembled. The gripping surface 15 is in the form of three recesses arranged in a circumferentially extending relationship in the vicinity of the active end 12. These recesses are configured and shaped to match the belly of the human thumb and forefinger, allowing a better and firmer operation of the tool and providing a more comfortable operational feel. Again, the lifting aid 20 has a tubular nature and has two inclined surfaces 24 at the passive end 14 which are arranged in a relationship displaced by approximately 180 ° around the main axis of the operating tool.

  Finally, the lifting aid of the operating tool according to the present invention has been described with reference to a writing tool as an example. However, this lifting aid can in principle be used by hand, and its configuration is substantially defined by an elongated area. It can be used with all tools and tools that are characterized.
