Retaining clip for writing implements

■ The innovation concerns a metal clip for Writing implements, in particular for ballpoint pens, fountain pens, lead pencils or the like, consisting of an upper Clamping element with prongs for fastening against the writing instrument body, one at a distance from the writing instrument e body extending retaining clip and one formed in the area of the free lower end of the retaining clip Terminal 1 em ent.

A known retaining clip of this type consists of a flat band made of Ketall, the clamping element of which consists of a at a distance parallel to the retaining clasp / insert bent tab consists that on the side edges' for fastening against a writing instrument body carries spikes. The clamping element consists of the rolled free lower end of the Retaining clip.

Furthermore, a retaining clip made of a full metal profile with a plastic coating is known, which has a large volume and complex fastening mechanism (swivel bearing) with forms the writing instrument body.

The innovation is based on the task of a retaining clip of the type mentioned in such a way that when thinner material is used, a high level of stability is achieved especially in the area of the clamping point against the writing instrument body as well as a good spring property of the | Retaining clasp is achieved and also has the appearance of the retaining clips made of solid profile material can achieve approximate shape design.

This object is achieved according to the invention in that the retaining clip has a U-, semicircular or cross-section has semi-elliptical profile, which in the area of the | Clamping element merges into elongated legs which |

Wear fixing spikes or the like. |

Due to the hollow profile, which can be easily shaped from a thin flat strip, despite a thinning of the material a stable one with good spring properties Retaining clip are produced. In the area of the clamping point, the molded legs produce a advantageous transmission of the bending forces between the retaining clip and the attachment to the writing instrument body.

The retaining clip is for attachment to the body of a writing instrument made of metal and plastic and has the appearance of the complex full profile retaining clips vicinity.

Preferred further developments of the innovation emerge from the other claims for protection.

Below is one embodiment of the innovation explained on the basis of the drawing. It shows:

1 shows a perspective view of a retaining clip, FIG. 2 is a plan view of the retaining clip according to FIG. 1, 3 shows a writing instrument body with a clamping element of the retaining clip to be fastened thereon, 4 shows a side view of a writing instrument body with a retaining clip.

The one made of a U-shaped, semicircular or elliptical profile that can be made from a thin metal strip is, existing retaining clip for writing implements has a retaining clip 1, a clamping element 2 for attachment on a writing instrument body 3 and a clamping element 4. In the area of the clamping element 2, the profile merges into elongated legs 5, which carry fastening prongs 6, which can be locked against the writing instrument body 3.

PE 064-02 March 6, 1979

Even with a small material thickness, the legs 5 can have high bending forces between the retaining clip 1 and the Transfer clamping parts on the writing instrument body. Included the profile creates the impression of a full profile material. An improved locking of the retaining clip with the writing instrument body is achieved when the end of the fastening prongs 6 - ^ nden 7 of Legs 5 of the clamping element 2 are bent outwards by lines 8 running approximately parallel to the retaining clip 1 are.

At the top, the tensioning element 2 has a perpendicular to the retaining clip 1 between the legs 5 bent end piece 9, which is from the profile back of the expiring Retaining clasp 1 is formed and covers the gap between the two legs.

A construction of the clamping element s 4 similar to a full profile results from the fact that the profile of the retaining clip 1 molded laterally in the contour of the clamping element Has flaps 10 and an elongated end piece of the profile back is bent between the tabs.
