Description

The invention relates to a device for sharpening a rod-shaped object, in particular a writing, drawing or cosmetic pencil, comprising a handle portion at one end in the longitudinal direction a sharpener body is arranged with a sharpening knife, wherein the handle portion at the opposite end of the sharpener body a Has recess in which a provided with a handle element tool is used at least partially.

Spitzerbehälter with additional containers are known from the prior art, see. DE 9 104 528 U1 , The pencil, color pencil or cosmetic pencil sharpener described therein provides a sharpener consisting of a sharpener housing and a knife in a chip container. In addition to the chip container, at least one additional additional container for receiving small parts is present, which forms a structural unit with the chip container. In this case, a plurality of additional containers can be arranged tower-like one above the other via a plug connection.

The invention has the object of providing a device for the tip of a rod-shaped article with the features of the preamble of claim 1 such that both the handling during sharpening and the handling of a tool with the respective handle elements is easy and in the non-use state of the sharpener and / or at least one tool, the overall device occupies a small volume. It is another object of the invention to form the device such that it is both inexpensive and easy to manufacture and can have a variety of different tools.

This object is solved by the features of claim 1. Advantageous developments of the invention will become apparent from the dependent claims 2-15.

As the core of the invention, it is considered that the gripping element is provided at the opposite end of the tool with a recess and the recess of the handle member is dimensioned such that the sharpener body is at least partially usable in these, the sharpener body together with grip part force and / or positively connected to the handle element and the handle element together with tool non-positively and / or positively connected to the handle part. Due to the fact that both the grip element and the grip part each have a recess into which the tool or the sharpener body can be inserted, at least in some areas, it is possible to arrange the sharpener body in the recess of the grip element as well as in a second order in a first order Store tool in the recess of the handle part. Thus, at least two constellations for the juxtaposition of handle and handle element are realized. This makes it possible that in the non-use state of the device by the Aufeinandersteckbarkeit the individual elements, the overall device occupies a small volume.

It has proven to be advantageous to dimension the grip part in such a way that it essentially corresponds to the length, height, diameter, outer contour shape and / or the volume of the grip element. A significant equivalent is to be understood as a maximum deviation of +/- 20% of the grip part to the grip element. In a particularly advantageous embodiment, the grip part and the grip element are identical. This makes it possible for the grip element and the grip part to use the same component. For example, if the two handles are designed as plastic injection molded parts, one and the same mold can be used for their production. Thus, the production costs are significantly reduced since both the handle part for holding the sharpener body and at least one grip element for holding at least one tool can be manufactured from the same injection-molded plastic mold.

In order to support the basic idea of the same or identical and therefore uniform grip (grip element and grip part), it is advantageous if the grip part and / or the grip element is provided with a connection region in which an adapter can be fastened, wherein a tool is attached to the adapter or the sharpener body is attachable. The adapter thus provides a link between the handle portion and the sharpener body or between the handle member and a tool. For example, if the handle portion and the handle member are identical, but the fixing portion of the sharpener body and the fixing portion of a tool are different from each other, the adapter allows Fixing the fixing area with the respective handles (handle or grip element). In this case, for example, two different adapters can be provided, wherein the fixing area of the sharpener body can be received with the first adapter and the fixing area of a tool with the second adapter, wherein both adapters can basically be placed in a similar connection area of the grip part and the grip element. This makes it possible, using a uniformly attachable to the handle part and the handle member adapter that is adapted to the different fixing areas of the tools and sharpener body to attach different tools and sharpener body to the handle parts and handle elements. The adapter can be used both in a recess of the connection area as well as attached in any other way to the connection area.

The non-positive and / or positive connection of the sharpener body together with the handle part and the handle element together with the tool with the other connection partner, for example, via the adapter, wherein the Adapter on the handle part or on the handle element forms a connecting element in the non-positive and / or positive connection of the handle element and the handle part. Thus, the adapter has a dual function. On the one hand, the connection of a tool or a sharpener body with a handle part or a handle element and on the other hand ensuring a positive and / or positive releasable connection between a first and another handle member or a handle part.

In principle, the adapter can be designed as an integral element on a sharpener body or on a tool. Alternatively, the adapter is formed as a separate element with recesses or emphasis that allow attachment of the sharpener body or a tool.

According to a preferred embodiment of the invention, the device has at least one grip part with a sharpener body and at least two grip elements each with a tool. It is advantageous if the tools of the at least two gripping elements are different in nature. For example, the tool of at least one handle element as tweezers, powder brush, eyeliner brush, nail file, mascara brush, cleaning rod, contact lens storage device, mirror, lipstick, knife, scissors, ruler, toothpick, writing instrument (eg, felt-tip pen, pencil, crayon, rollerball, Gelroller, chalk) trained. Thus, it is possible in a device, for example, to provide a gripping part with a sharpener body, a gripping element with a pair of tweezers and a gripping element with a cosmetic stick and inserting them into one another. Characterized in that the handle part and the handle elements are arbitrarily combinable, it allows a user of the device to assemble for different occasions a freely selectable combination of the tools and the sharpener body and to carry with him.

Furthermore, it is advantageous if the tools of the at least two gripping elements are each dimensioned in their maximum extent such that they can be inserted into the recess of the gripping part and / or of the gripping elements. Consequently, it is also advantageous if the recess of the handle part and the recess of the handle element in their shape, dimensioning, volume and / or in their arrangement are the same. Thus, the arbitrary combinability and ability to connect the individual elements is achieved.

The connection of a gripping part to a gripping element can preferably take place in that an engagement element (eg a snap-in nose) is arranged in the inner region of the recess of the gripping part of the gripping element, which is arranged with a counter element (eg a groove corresponding to the snap-in nose) ) of the adapter of a handle element and / or a handle part cooperate. In addition to a snap-lock connection, other positive-locking (eg bayonet lock, thread) and / or non-positive (eg clamping connection) connection principles are also possible.

In a particularly advantageous embodiment, the device has a connecting body, which has at least two recesses, in each of which a tool and / or a sharpener body can be inserted. The connecting body thus has at least two connection points, to which the gripping parts or gripping elements provided with the sharpener body or a tool can be attached. For example, the handle parts or gripping elements can be arranged lying next to one another in parallel on such a connecting body. A star-shaped arrangement is also made possible by a central connecting body. In a further embodiment of the connecting body, the latter has a hinge element or a plastically or elastically bendable region, wherein the hinge piece or the plastic or elastic region is arranged between at least two connecting regions for receiving grip parts or grip elements. As the engaged with each other standing handle parts and handle elements in the assembled state form a predominantly rod-shaped body, can be achieved by the arrangement of the above-described connecting body in the middle of the rod, a collapse or bending of the rod and thus the maximum longitudinal extent of the rod can be reduced.

It is further proposed for the tool in the assembled state of the device to be exposed and / or the exposed sharpener body to provide a further closure body which has a recess for receiving the sharpener body and / or the tool and can be attached to it in an enveloping manner. In a preferred embodiment, the closing body is sleeve-like and formed with two openings, wherein at one of its free ends, a lid member can be attached. Preferably, a rod-shaped tool can be incorporated in the cover element, such as a cleaning pencil for a sharpener. It is also particularly advantageous if the closing body is at least partially made of the same mold as the handle part and the handle element. Thus, the closing body is formed in its geometry identical to the handle element and / or the handle part.

The connecting body, the closing body, the grip part and / or the grip element are advantageously formed at least in regions from a transparent material. By choosing a transparent material, it is possible for the user to recognize which tool is located on which grip element and in particular under which grip element, grip part, end body or connecting body. This makes it easier for the user to find the tool of his or the sharpener body in the assembled state of the device.

In a preferred embodiment, the gripping part, the gripping element, the closing body and / or the connecting body are designed substantially as a sleeve-like, rod-shaped element.

A further advantageous measure is to provide the peripheral surface of the grip part and / or the grip elements with different markings. The markers may include both optical and haptic markers. Thus, it is possible, for example depending on which tool is attached to a handle member to provide different color marks, labels, surface textures, etc., to facilitate the operator of the device in the mated state of the handle parts and handle elements, the tool desired by him or the sharpener body be able to find targeted.

According to the invention, the device is a sharpener and a tool set comprising at least one gripping part according to the invention and at least one gripping element according to the invention, wherein an assembly of at least one gripping part and at least one gripping element can take place together in any order.
