Description

The invention relates to a writing instrument with an at least partially hollow pen body and an elongated writing lead arranged in the pen body, the writing lead protruding at the front end of the pen body or the writing lead axially displaceable in the pen body from a transport position located inside the pen body to a writing position partly outside the pen body is arranged.

Such writing implements have been known for a long time and for a long time. They are used in almost all everyday situations and in the business world. In the case of writing implements for children in particular, it is customary to make them as visually attractive as possible for young users. Accordingly, writing implements are designed in a wide variety of shapes and colors. It is also common, for example, to arrange animal figures on the pen body.

Writing instruments have recently become less and less popular. Electronic touch-sensitive devices are becoming increasingly popular for writing and drawing, especially with young users, especially children. The skills in using conventional writing implements such as pens are therefore decreasing more and more.

It is therefore the object of the invention to develop a writing instrument of the type mentioned at the outset in such a way that the operation becomes haptically and visually more attractive and entertaining, especially for young users.

For this purpose, based on a device of the type mentioned, the invention proposes that at the rear end of the pen body opposite the front end of the pen body, an electronic switch device and a mechanical lever arm pivoted on the pen body are in operative connection with a mechanical operating switch.

When the mechanical operating switch is activated, the electronic switch device can be used to output acoustic or visual signals which can be used for entertainment, for example. The pivotably mounted lever arm swings out when the mechanical actuation switch is activated. The lever arm can be modeled on a human arm, for example, which is extended with the pivoting. This movement is also used for entertainment.

A preferred embodiment of the invention provides that the mechanical actuation switch is designed as a lever switch, which can be pivoted about an axis arranged in the pin body, a pressure surface is arranged on the actuation side of the lever switch and a drive pulley is arranged positively on the opposite switching side, such that the Drive pulley is set up to pivot the lever arm. This arrangement makes the operative connection between the lever arm and the actuating switch particularly reliable and low-wear. The lever arm and the drive pulley can also be designed in one piece.

An expedient development of the invention provides that the switching arrangement has an electronic circuit board, on which an electronic pressure switch is arranged as an electronic switch device, which is activated by means of the actuating switch. Additional elements can be arranged in a particularly space-saving manner on or on the electronic circuit board.

It is also advantageous if the electronic pressure switch can be reset by means of a mechanical spring. By means of the return spring, the pressure switch is returned to its original position in a reliable manner as soon as the actuation switch is no longer pressed.

A further development of the invention provides that at least one lighting means is additionally arranged on the circuit board. The light source can be activated by the electronic switch device. It can be used for entertainment, but also for lighting. In the latter case, means can additionally be provided which direct the direction of emission of the lighting means in a predetermined direction.

A loudspeaker can also advantageously be arranged on the circuit board. A wide variety of tones can be played using the loudspeaker, which can contribute to the entertainment of the operator.

In a further embodiment, the lever arm is designed in the shape of a boxing glove at its distal end. When the lever arm is swiveled out by pressing the actuation switch, the process is reminiscent of the arm of a boxer performing a punch.

An advantageous further development of the invention provides that the lever arm has a proximal section and a distal section, the proximal section and the distal section being pivotable relative to one another via a joint.

For the pivoting, it is particularly advantageous if a metal spring is arranged in the lever arm in such a way that the metal spring opposes the distal section of the lever arm pivoted proximal portion of the lever arm when the lever arm pivots. Due to the division into the two mutually pivotable sections, the lever arm resembles a human arm with an upper arm (proximal section) and a forearm (distal section).

Furthermore, the invention proposes that a cap is detachably non-positively and / or positively arranged on the pen body, by means of which the pencil lead can be covered.

In this way, the mine can be protected from drying out and leaking.

The invention is explained in more detail below with reference to the drawings. Show it:

In 1 a writing implement according to the invention is shown in side view. The writing instrument has a partially hollow pen body 1 on. At the top of the pen body 1 is a pen head 2 arranged. In the pen head 2 an electronic switch device, which is essentially not visible here and which is described in more detail later, is arranged. On the pen body 1 is also a mechanical actuation switch 3 arranged as a lever switch 3a around a pivot axis S. is rotatably mounted. The lever switch 3a is in operative connection with a trigger button assigned to the electronic switch device 4th and a lever arm 5 .

The operative connection is shown below using the 2a and 2 B explained in more detail. The lever switch 3a is made by exerting a force F about the pivot axis S. twisted.

The operative connection from the lever switch 3a to the lever arm 5 is via a drive pulley 6th realized. The lever switch 3a has a recess 7th on what protrusions 8th the drive pulley 6th partially engage positively. This creates the drive pulley 6th through the lever switch 3a taken along and twisted in turn, so that the lever arm 5 swings out. Additionally is in the lever arm 5 a metal spring 9 arranged over a joint 10 a distal section 5b of the lever arm 5 relative to a proximal section 5b of the lever arm 5 pivoted. The drive pulley 6th can be made in one piece with the proximal section 5a of the lever arm 5 be trained. The drive pulley 6th but can also be designed as a separate component and with the proximal section 5a of the lever arm 5 be positively and / or cohesively connected.

The operative connection between the lever switch 3a and the trigger button 4th the electronic switch device is via a wedge-shaped design of the trigger button 4th realized. Will the lever switch 3a around the pivot axis S. pivoted, it moves in the pen body 1 end of the lever switch 3a along the wedge-shaped surface of the release button 4th and pushes it upwards accordingly.

As soon as the lever switch 3a is released, so no more force F is exerted from these, the force of a return spring acts 11 on the upper end of the lever switch 3a and moves it back to its starting position (cf. 2a) .

3a and 3b show sectional views through the upper part of the pen body 1 and through the pen head 2 , the lever switch 3a in 3a is not pressed and in 3B a force F is exerted on this. In the pen head 2 is an electronic circuit board (PCB) 12th arranged. On the PCB 12th is a push button 13th arranged, which is in operative connection with the release button 4th stands. Furthermore are in the pin head 2 a battery 14th , which serves as an energy store, and a loudspeaker 15th arranged. The pen head 2 has openings 16 that is above the speaker 15th are arranged.

Will the lever switch 3a now actuated by exerting a force F on it, the push button is activated 13th via the trigger button 4th actuated. By pressing the push button 13th will play an acoustic signal through the loudspeaker 15th triggered. The acoustic signal can be a rather monotonous signal tone, but also a musical or verbal output. The acoustic signal penetrates through the openings 16 outward.

To control the acoustic signal, it is also possible to use a microcontroller (not shown here) with an integrated memory on the PCB 12th to be provided. It is also possible to have light sources in the pen head 2 to arrange the when pressing the lever switch 3a to be activated. In such an embodiment, it is particularly advantageous to use the pin head 2 at least partially transparent. The transparent parts can simulate a pair of eyes or the like, for example.
