Ballpoint pen with calendar "

Many people do not have a calendar to hand when writing, to be able to determine the date. Lan can imagine in such a case that it would be useful to have a ballpoint pen or to have and be able to use some other writing implement that has a calendar that provides the requested information to those who need it. The present invention solves this problem in such a way that the writing implement remains completely secured, in particular screwed, and every payer when reading the date.

The invention is explained in more detail below using an exemplary embodiment with reference to the accompanying drawings described. The description and the exemplary embodiment are not intended to constitute the protected subject matter of the invention restrict; rather, the protection is intended to include all modifications

in details, in shape, dimensions and material, if none include the essence of the invention Reasonable modification of the features is available.

ji'ig. 1 corresponds to a side view of the calendar bearing section of a ballpoint pen with a hanging that is at de: - the writing tip applied end of the scribe by a Schrauoe is held.

FIG. 2 shows, in a view corresponding to the representation according to FIG. 1, a similar embodiment, which, however, has been improved by the fact that the hing, which can be rotated (rotating ring) , with one acting as a branch protrusion Is provided with a tip that can snap into a notch in the body of the ballpoint pen,

Fig. J also shows a lead side view with a modified form of the coupling of the rotating ring between z *, vei sections or parts of the bullet screamers body.

Fig. 4- shows the side view of a ballpoint pen in • that of the rotating ring and the thread element of the ballpoint pen are separated.

Fig. 5 shows one of Fig. 4- substantially corresponding View of a ballpoint pen, in de ^ the Rotary ring represents the receiving cone of the writing tip and from this writing tip when screwing this tip into the ballpoint pen body is worn and held.

6 shows another Ausführungsforia in which the rotating ring between zv. ^r ei interconnectable parts or sections of the body of the scream binstruiaentes can be used and adjusted, the writing implement having the usual shape of a ballpoint pen, which consists of two parts that can be screwed together.

In ü'ir · 1 one sees the ballpoint pen body 1, in its seven outer surfaces or seven columns of numbers in its cylindrical surface running in the longitudinal direction each of which corresponds to one of the lonat number columns 4-, like them on one. Calendar appear. They have consecutively from top to bottom the following columns of numbers: " Column or column 1: 1,6.15, ^: 2.29;

Column 2: 2,9,16,25,30;

Column 3: 3,10,17, ^, 51;

Column 4: 4, 11, 18, .15;

Column 5: 5,1 ^, 19, ^ 6;

Column 6: 6,13, ^ 0, ^ 7 and

Column 7: 7.14, -1, _8.

IUi t reference symbol _t . is a rotating element, which on its outer surface roughly follows the shape of a ballpoint pen and on which the first letters t of the days of the week are written on the outside: L, D, I .., D, F, S, b (or ^ o, Tue, LIi, Thu, Fri, Sa, Sun), this rotating piece 2 is perforated on the inside for the passage of a threaded pin = (Fig. 4, = ■ and 6) around which the rotating piece (rotating ring) is able to rotate, whereby it it is possible to set the first letters of the weekdays to the numbers of the month days on the ballpoint pen body so that they correspond to the present day so that:

before the ballpoint pen takes on the function of a calendar can. The whole thing is fixed and secured by the screw pin 5.

This inventive device has the advantage of each Type of pen to be adapted: To the one-piece, which is reloaded through the tip (Fig. 4- and 5) i and the two-part, which by separating the both parts is reloaded (Fig. 6). When the rotating member (for example rotating ring) is in the rear part of the ballpoint pen is to be attached (Fig. 4), it is by means of a threaded screw 5 and a notch in the screw head 5 'set. When arranged in the middle (Fig. 6), the adjusting member, e.g. as a rotary ring, is between the two parts of the pen set that be unscrewed through the thread 5 to insert the replacement lead. When the adjuster is located in the lower part of the ballpoint pen (Fig. 5), it is adjusted using the replacement refill, which is supplied with a thread 5 is provided.

One of the serious inconveniences of this device consists in the fact that the thread 5 gradually loosens, be it because the cap of the ballpoint pen is stuck or be it by some unintended friction} the rotary member 2 in any case slightly changes its position and can then no longer correctly enter the date of the month.

This disadvantage is illustrated in FIGS. 2, 3 and 6 features shown are eliminated by namely the contacting surfaces of the ball pen body 1 and rotating element 2 with one or more protrusions 6 in one surface and seven corresponding

corresponding recesses 7 in. The other Ouerfläche provided are, wherein the projections are arranged and formed that they are by means of the pressure from the thread axis 5 are locked in place so that the rotating element remains practically anchored and does not slide unexpectedly can.
