DE202005014672U1 - Writing, painting or drawing means for wax crayons, chalk or leads has cylindrical sleeve with longitudinal slot and number of recesses for engaging of cursor which acts upon element for writing - Google Patents

Abstract

The writing, painting or drawing means for wax crayons, chalk or assembled leads consists of a cylindrical sleeve (4) which on the inside contains an element for writing. The sleeve is provided with a longitudinal slot (10) and a number of recesses (12) for the engaging of a cursor which acts upon the element for writing so that the point of the element can protrude from the sleeve and retract back into it. A grip (5) of slip-resistant material is attached at the end of the sleeve opening.

Description

These Innovation relates to a writing, painting or marking agent for wax paint, Chalk or correspondingly assembled mines.

On the market writing means are known which consist of cylindrical plastic sleeves and in which a crayon or chalk (request of the Italian Usage model 30669/88) is used; contain these pods a cursor that is in a snap notch of wax crayon or chalk and which can be moved back and forth within the plastic wrap around to move the crayon color; so the writing or painting medium can be completely used up become.

Besides, they are plastic bags for crayons - and chalk known to have a hexagonal or triangular exterior and Inner cross section for have a more correct and ergonomic handle (DE 20304750U1 and DE 20319632U1).

The Making these sleeves is quite complex; This is especially true for both the inside and the outside Outside triangular pods, for this their production requires very complex punching.

It also stays the building material (usually polystyrene), - even if it is on the gripping surface for the hand with longitudinal grooves or markings -, a very smooth material that does not allow a "holding on" by hand, especially when the user is a child.

There it is the writing or painting medium described here for the most part for crayons for Children are, it is clear that a better adherence to the Hand and a correct and ergonomic handle, as well as the simple Making the sleeve thanks their predominantly round shape, for the user brings significant benefits.

There are also there is another problem: as the wax crayons or chalk in the Interior of the sleeve slide freely and exit easily from the front opening of the sleeve should the diameter of the latter be smaller with respect to the sleeve opening; the resulting cavity between the two diameters lets the Crayon paint pen moving and during writing / painting against the walls the sleeve "strike", which is very disturbing.

aim Therefore, the innovation is the same as the above described problems eliminate and a sleeve for the Wax paint or chalk with a soft rubberized handle and non-slip material that "catches" the wax crayon during the Use of the writing medium allowed.

This goal was achieved according to the innovation for writing, painting or drawing materials with wax paint, chalk or correspondingly composed mines. The writing means consists essentially of a cylindrical sleeve ( 4 ), which contains the element called for writing inside. This sleeve is provided with a longitudinal groove ( 10 ) and a plurality of recesses ( 12 ) for locking a cursor ( 16 ) Mistake; it acts on the element called for writing in such a way that the tip of said element can escape from said sleeve and reenter it. This is done in that at the end of the sleeve opening a ring element is attached as a handle made of non-slip material.

These Innovation will be described below with reference to the accompanying drawings explained in more detail:

The 1 shows in perspective a writing means according to the present innovation;

the 2 shows this in compound form, and

the 3 . 4 and 5 show three grip types with different shape.

As you can see on the pictures, the writing medium according to the innovation includes a wax crayon 2 having a substantially cylindrical shape. The top and the sleeve 4 are made of plastic material and the outer edge has a substantially rounded cross-section, with a front longitudinal groove 3 , There is a grip on the front of the sleeve 5 between two raised facing 8th Keep him firmly in his seat. This grip is made of non-slip rubberized plastic with cross sections of various shapes and it covers the groove 3 from. The writing means includes a cylindrical cavity 6 for the complete insertion of the wax paint.

The lateral surface of the sleeve 4 has a slot 10 with a variety of recesses 12 , the locking of a rubber tooth 14 serve. This is located on a cursor, which is firmly attached to the bottom of the crayon.

The spelling with the renewed writing means corresponds to the traditional spelling of crayons with sheath. The user presses the tooth 14 to free him from the recesses and the cursor 16 to allow the crayon inside the sleeve to move so far that the tip of the crayon is out the cavity 6 protrudes.

There the grip is made of very elastic material, he transmits when writing or painting with your fingers is squeezing the pressure on the underlying also thanks to the slot elastic sleeve. These tightens tightly around the crayon and prevents that this during the use of the writing means disturbing back and forth.

Also allowed the application of the said grip the production of only this Component in various forms, such as round, curved, triangular, hexagonal and any other shape by a simple punching technique Thermosplast is feasible.

As soon as the crayon is no longer used, it pushes the user with a movement analogous to the previous movement back into the sleeve, so that the tip is no longer visible.

• – Sie erlaubt einen perfekten Griff dank der weichen und rutschfesten Grifffläche;
• – sie erlaubt die Arretierung des Wachsmalstifts während der Benutzung, dank des vorhandenen Schlitzes;
• – der Griff ist ergonomisch und hat die gewünschte Form;
• – die Kosten sind gering, da die Hülse mit dem runden Querschnitt einfach zu realisieren ist.

The predicted shows clearly the numerous advantages of writing with the renewed writing medium. Especially:

• - It allows a perfect grip thanks to the soft and non-slip grip surface;
• - It allows the locking of the crayon during use, thanks to the existing slot;
• - The handle is ergonomic and has the desired shape;
• - The cost is low because the sleeve with the round cross-section is easy to implement.
