Description

[Detailed Description of the Invention] A writing instrument with a clip, which has a notch at the shaft portion of the writing instrument or at the location where the clip is fixed to the cap, and the fixing member of the clip fits into the notch at the fixing location. Concerning the type of thing that is required.

Such a writing instrument is known, for example, from German Patent No. 277 252. A disadvantage of known writing instruments is that the clip is always installed only from one direction and therefore cannot be installed mechanically at all or without great expense. Additionally, a seal or other additional insert is required to hold the clip securely. Furthermore, the characteristics of the clip, such as the type of clip, can be identified only from one direction. Therefore, if the type of writing instrument is to be indicated by the color of the clip in order to easily identify the writing instrument from all directions, the end face or other side of the writing instrument must be marked in color.

In contrast, the Federal Republic of Germany application no.
In the writing instrument known from specification No. 2335211,
The clip is pushed from the side into the notch of the writing instrument and is held in place by a knob or claw. However, in this case as well, the installation of the clip and the identification of the writing instrument are only possible from one direction, and the sealing element and other additional inserts are only secured using additional means.

Furthermore, the specification of Utility Model Publication No. 41-5610 and Utility Model Publication No. 43-
In the writing instrument or the cap for a writing instrument known from specification No. 12981, the clip can be pressed in from the side (Utility Model Publication No. 41-5610) or from above in the axial direction (Utility Model Application No. 43-12981). There is. The clip has a locking element which engages in a recess provided in the cap and is secured by a positive fit. In this case, the clip portion is visible from the end side of the writing instrument. However, in this case it is not possible to use the fastening elements of the clip to fasten or securely hold other components together. Furthermore, the type of writing instrument can be identified only from two directions at most. Particularly, identification is impossible from the direction opposite to the clip.

It is therefore an object of the present invention to improve a writing instrument with a clip of the type mentioned at the outset, so that the type of writing instrument can be easily identified, the writing instrument can be produced at a significantly lower cost with fewer working steps, and it can be easily and easily clipped. It can be mounted quickly, possibly mechanically (automatically), and furthermore, the insert, which is designed as a sealing element or plug, can also be fastened quickly and reliably, so that no additional identification means are required. It is to be.

In order to solve the above problems, the present invention has the following features:
The notch in the fixing point of the clip to the shaft or cap and the fixing member of the clip at least partially pass through the fixing point in a direction perpendicular to the longitudinal axis of the writing instrument, and the notch in the fixing point is formed by the slit. It is open towards the end of the writing instrument,
The minimum slit width of the slit is smaller than the maximum notch width of the notch at the fixed location,
The insert, designed as a sealing element or plug, has a recess into which the fixing element of the clip fits.

According to the invention, the notch in the fixing point of the clip to the shaft part or the cap of the writing instrument and the fixing member of the clip at least partially pass through the fixing point in a direction perpendicular to the longitudinal axis of the writing instrument,
By opening the notch at the fixing point toward the end surface of the writing instrument with the slit, the fixing member can be easily pushed from the side into the notch at the fixing point in the cap or shaft part. The clip attached to the writing instrument is exposed on the surface of the writing instrument on at least three sides (the front side, the side side, and the end side), and the type of writing instrument can be easily identified from the color and shape of the clip, and the sealing member or The insert configured as a closure plug is provided with a notch that matches the shape of the clip fixing member, and when the clip fixing member is pushed into the notch at the point where the clip is fixed to the cap or shaft part, the insert is inserted. By pushing the insert into the recess of the shaft part or cap, the insert can be rotated easily and reliably without the need for additional components and separate working steps, and the minimum slit width of the slit can be Since the width of the notch at the point where the clip is fixed is smaller than the maximum width of the notch, the fixing member of the clip can be attached to the shaft with a positioning effect by form-fitting without the use of additional tools. It is fixed in the notch at the fixing point of the cap or cap.

In writing instruments whose cross section is not completely circular but oval or polygonal, or which has at least one flat side, it is advantageous if the notch and the fixing member extend parallel to the flat side. It is. In this case, the clip gripping pieces of the approximately U-shaped clip are always in reliable contact with the flat sides, resulting in a good clipping action.

The clips are optionally made of metal or plastic and may be constructed of various materials or components.

If emphasis is placed on the identification of the type of writing instrument, it is advantageous if the clip gripping piece, transverse web, connecting web and fastening element of the clip have the same characteristics, for example the same pattern or the same color. With this, the type of writing instrument can be identified, for example, by the clip holding piece from the front of the writing instrument, by the connecting web from both sides, and further by the lateral web from the end side.
That is, it is possible from four directions.

It is particularly advantageous if the cutout passes completely through the fixing point, making it easier to identify the type of writing instrument.

If the width of the notch at the fixing point is narrowed towards the slit, for example into an approximately trapezoidal shape, the notch produces a wedge effect.

Advantageously, the clip has an extremely simple structure.
A curved clip holding piece, a transverse web extending substantially perpendicularly to the clip holding piece in the direction of the shaft or cap, a connecting web extending from the horizontal web in the same direction as the clip holding piece, and a fixing member connected to the connecting web. It is integrally formed into a nearly U-shape.

In order to make it possible to easily replace the clip or the insert as a sealing element or plug, as the case may be, the fixing element of the clip is removably arranged in the fixing point and in the recess of the insert. It is advantageous.

However, in order to prevent the fastening part of the clip from undesirably coming off, it is advantageous if the recess of the fastening point has a radially oriented projection or recess as a fastening means for the inserted fastening part; In addition, the fixing member has a radially oriented recess or protrusion corresponding to the protrusion or recess of the notch of the fixing location.

If the shaft or the cap of the writing instrument is customarily designed as a hollow body, the recess of the fastening point and the fastening element of the clip preferably pass completely through the fastening point.
