Sleeve for wax crayons

The innovation concerns a sleeve for wax crayons made of resilient material, such as. B. plastic. People have always been interested in the easily breakable ones Chalks (pastel chalks., Blackboard chalks, Oil crayons and the like) with a sliding sleeve, which is additional to the chalk pen Gives stability. While in earlier times it was preferable to use slotted and thus resilient metal sleeves used, which were usually also equipped with a sliding ring, so one uses recently also for this purpose of plastics. One makes plastic sleeves, either through slots or by deformations that deviate from the circular shape in cross-section, are characterized and fixed lie around the wrapped pen. So you have a completely or partially slotted sleeve for this purpose suggested. In such sleeves, however, chalk pens slide back and forth and especially when they have already been processed considerably, i.e. are only relatively short, the mounting is problematic. The break resistance is also to be judged negatively, because on the exerted during the drawing Pressure the slotted sleeve gives way too easily without securing and then the pin breaks after all.

Other suggestions are that the sleeve, which is initially made in the shape of the pins, is placed in places deformed out of round. The bracket may be a bit safer here, but working with dai Pins to prevent the sleeve from slipping.

The innovation eliminates these disadvantages in a simple manner

Wise. It consists in that in the plastic sleeve open handle windows are incorporated. So it will a normal sleeve is used, which is adapted in diameter and cross-section to the pieces of chalk and this In its front part, the sleeve has at least one, preferably several window-like openings that it allow the pen to be grasped directly through this window. That way it will affect everyone Case avoided that the pin can move in the sleeve during work. Because the sleeve stuck lies around the pin, it cannot bounce or bounces only a little, so that it is break-proof as well given as possible, especially since the sleeve is now pushed very far towards the tip of the pen can to reduce the leverage of the writing pressure.

The handle windows can also contain webs, ie now act independently resilient and serve the grip strength.

You can also cut out tongues from the sleeve shell, which in turn act like spring flaps, if you take hold of these tongue flaps when handling the pen.

The attached sketch shows the innovation in an exemplary embodiment.

Figure 1 shows a colored pencil (e.g. wax crayon) 1, which is coated with a plastic sleeve 2. A handle window 3 is recessed in this plastic sleeve, that is big enough to be able to touch the pen 1 itself with the finger of the drawing or painting hand to be able to grasp. Here is only one such window 3

shown graphically. But it is also more advantageous to install two such windows j5 in the sleeve 2, which then face each other on the jacket of the sleeve.

Figure 2 again shows the plastic sleeve 2 around the crayon 1. The handle window is this time in Recesses 4 with grids 5 in between have been modified. These recesses and grids can be arranged evenly distributed around the front part of the sleeve. But you can also only have one area occupy a total of approximately the area of the window in Figure 1. Here is the index finger no longer gripped through the recesses on the piece of chalk itself. Rather, the recesses 4 have an effect an increased spring force of the otege 5. » which are easily pressed against the pen 1 by finger pressure can so that it sits firmly in the sleeve during the work process.

Figure 3 shows a further modification of the concept of innovation. Here are 4 instead of the recesses Figure 2 tongues 6 attached, which in turn resilient and the pressure of the fingers encompassing them on the Pass on a piece of chalk so that it is held firmly in the sleeve during the operation.
