Device for preferably pen-like writing or drawing implements to protect the fingers

The invention relates to a device for preferably pen-type writing or drawing implements, e.g. fountain pens, Ballpoint pens and pencils to protect your fingers.

People who work a lot with pens or pencils often complain of painful pressure points on the fingers with which they hold the mostly pen-like writing or drawing implements. This is particularly true Measure too much for schoolchildren with still tender fingers, of which no loose guidance of the writing or Drawing devices can be expected, but which hold the devices with firm finger pressure.

The present invention was based on the object of remedying this disadvantage and a device for protection of the fingers that are attached to writing or drawing implements during their manufacture or afterwards can. According to the invention, this object is achieved by that with this device the writing or drawing instruments in the area of the finger contact points yield a Obtained upholstery, which is achieved in a preferred embodiment by a plastic mass, which, at least outwardly bounded by a flexible cover, on the outside of a writing or drawing instrument is arranged.

To take up the plastic mass, the writing or drawing implements are expediently equipped with one or more Provided wells, for example with a relatively flat annular groove around the pen-like writing or

Drawing device, and these recesses are outwardly through a flexible wall, for example a plastic film, limited, the edges of which are firmly connected to the device, so that no plastic mass from the Padding areas can escape.

The flexible cover films can be fastened in various suitable ways, for example by means of Clamping rings that are attached to the outside of the device, or through a direct connection the edges of the foils with the outside of the writing or drawing implement by gluing or welding.

The plastic mass is arranged in the cushion chambers in such an amount that it is there under the pressure the finger grasping the writing or drawing instrument has a limited displacement with deformation of the outer flexible boundary wall can suffer. This can be caused by incomplete filling of the upholstery chambers or by using an elastically resiliently deformable outer wall when the wall is completely filled Padding chambers can be achieved. Under the pressure of the fingers holding the writing or drawing instrument so the plastic mass located at this point is partially displaced laterally, so that there is a hollow for each finger forms. The contact surface of each

The finger on the writing or drawing instrument is thus enlarged and thereby the specific surface pressure on the finger skin reduced, quite apart from the fact that the fingers grip a resilient padding surface. Be that way painful pressure points on the fingers avoided even when writing or drawing for a long time. To increase the Grip of the upholstery outer surfaces can affect the boundary wall that comes into contact with the fingers plastic cash register with a suitable profile.

Further features of the invention emerge from the following Description in conjunction with the drawing, on the two embodiments of a device according to of the invention are shown in a highly schematic manner.

Show in detail:

1 shows a schematic central partial section through a fountain pen in the region of its nib end ;

FIG. 2 shows a perspective partial illustration of the fountain pen shown in section in FIG. 1, gripped by the fingers of one hand in the writing position;

Fig. 3 shows the partial representation of a pencil with a plug-on sleeve formed according to the invention, shown in section, is provided.

In the embodiment of Figure 1, the fountain pen 1 provided for a spring 2 with a relatively wide and flat annular groove 3 with a plastic Mass 4 is filled. The annular groove 3 filled with the plastic cash register is held by a hose section 5 made of elastic, flexible plastic. The ends of the plastic hose 5 are made of metal rings 6 and 7f in correspondingly shaped annular grooves 8 and 9 are arranged at least partially sunk on the outside of the fountain pen 1, on the outside of the fountain pen 1 firmly and tightly anchored.

When a finger, indicated by a dashed line 10, is pressed against the upholstery, the upholstery becomes plastic Mass partially displaced laterally, the plastic tube 5 being characterized by its elastic properties can bulge like a bead, as is the case at point 5 'in FIG.

From the perspective view of the same fountain pen provided with padding in Figure 2 it can be seen how all three fingers 10, 11 and 12 of a hand holding the fountain pen have trough-shaped depressions in the original 909831/0094 bad padded by means of a plastic compound

cause th section on the spring-side '.and of the fountain pen and thereby have a comfortable, shape-adapted seat on the pen, so that no painful pressure points can occur on the fingers.

In Figure 3 is another embodiment of a device shown according to the invention. Here the upholstery is designed in the form of a clip-on body 13, which can be pushed onto a pencil 14, for example. The slip-on body consists of a cylindrical one or polygonal inner sleeve 15. This inner sleeve is expediently made of a more or less elastic plastic, so that it follows the outer shape of the The writing or drawing implement onto which it is slid can adapt. Around the inner neck 15 is a bag-like one Cover made of an elastically flexible plastic film 16 arranged, // oak with a plastic Mass 4 filled cushion chamber limited to the outside. The ends of the plastic film are with the inner sleeve 15 in Area of their! Find firmly connected by welding after the plastic material has been introduced. For support a certain shape of the upholstery and the filling of the cushion chamber with the plastic material is the Inner sleeve 15 is provided with a conically extending flexible Hingflansoh 17 in the area of its one end.

The device according to the invention can be produced and attached in a variety of embodiments. So could For example, on the outside of a writing or drawing instrument, several separate fingers that attack individually assigned to the hand guiding the device, filled with a plastic mass and covered by a flexible film outwardly covered hollows may be provided. In addition, the flexible outer wall of the cushion body can be different suitable ./is profiled. A plastic lass does not necessarily have to be used as the upholstery material. A liquid filling could also be provided or a filling made of relatively soft, firm material, ζ.?, made of foam rubber or foam.
