Definitions
- the invention relates to the extension of partially or highly used pencils.
- German patent application 103216 of 1898 describes a sleeve for slate pins in which the slate pins are held by means of resilient notches. Also known is the solution according to German utility model 1 770 517, which proposes inserting a new pin over its entire length into a metal sleeve. This metal shell has a slot so that a pin that has been pushed in too far can be pushed out again using a knife or nail.
- DE 20 2010 018 125 specifies an actuating means comprising an elongated cavity and an opening to the environment in connection with the cavity, which can hold a correspondingly elongated object such as e.g. can at least partially pick up a carpenter's pencil and hold it.
- This actuating means is used in a tool for use in installing a vapor barrier apron, wherein the vapor barrier apron comprises a series of surface elements including side surface elements, which extend substantially along a longitudinal axis, and upper or comprises lower surface elements extending substantially along a lateral axis perpendicular to the longitudinal axis, each
- the insertion means comprising a surface for exerting pressure and sliding on the installation means and being connected to the actuation means at at least one point.
- a writing instrument holder which protects the body of a writing instrument and enables the operator to use the writing instrument for so long and keep it until it becomes too short to otherwise effectively use it.
- This writing instrument holder is formed from a container with an opening at the upper end, an opening at the lower end, a plurality of incisions next to the opening at the lower end and a longitudinal opening in the longitudinal direction of the container.
- a pen extension made from plastic by VELUX is only about 7.5 cm long and, compared to a pen, has a significantly larger, rectangular cross-sectional area, which does not significantly improve the handling of particularly shortened pens.
- this extension has an unfavorably shaped, stiff clamp, with which the previously described problems of insertion and accessibility are only partially solved.
- the object of the invention is to propose a solution which allows a quick, familiar and mostly intuitive use of shortened pens without restrictions.
- these images are based on a carpenter's pencil, for all other pencils with leads that wear out the shape is the
- Figure 1.1 shows the lower, open end of the extension for pins with wearing leads with the detail, for example, of two slots 2 of appropriate length in the longitudinal direction in the lateral surface,
- Figure 1.2 shows in detail a retaining spring 5
- FIG. 1.3 shows in detail the cap 6 with the part of the lock 7a arranged on the cap 6 and the clamp (clip) 8 in the joined position
- FIG. 1.4 shows in detail the cap 6 with the part of the lock arranged on the cap 6 7a and the clamp (clip) 8 in a non-joined position.
- Figure 2 shows the extension for pencils with wear leads in section
- Figure 2.1 shows in detail a retaining spring 5
- Figure 2.2 shows the section A-A through the extension for pins
- FIG. 2.3 shows a section through the cap 6 with the magnet 9 visible.
- the extension for carpenter pencils is preferably realized by a thin-walled hollow profile made of plastic with an appropriate length, the inner cross-section of which is adapted to the shape of the common pencil cross-sections. To facilitate insertion, to compensate for manufacturing tolerances of the pins with regard to the cross-sectional area and to adequately fix the pin in the extension, the following are listed below
- the extension at the lower, open end has one or more slots 2 of suitable length in the longitudinal direction
- bottom means the side of the extension on which the sharpened end of the pen is located
- top means the other side accordingly.
- the height of the elevations 4, which can increase somewhat in the insertion direction of the pin, is chosen so that they slightly notch the pin when it is inserted.
- the height of the elevations 4 on the side of the extension on which the pin is inserted is reduced linearly to zero over a suitable length 4a.
- Partial areas of the outer surface of the extension referred to here as retaining springs 5, are located, which are connected to the remaining outer surface on the side towards the upper extension end and are separated from this in the remaining area. When the pen is inserted, these retaining springs 5 are pressed elastically outwards.
- the upper, open end of the extension can be closed with a lockable cap 6, the end surface of which corresponds to the outer cross-sectional area of the
- Extension corresponds and on which there is a perpendicular piece of a hollow profile with an outer cross-section that corresponds to the inner cross-section of the extension, and which has a device for locking the cap 6 in the extension 1, consisting of elements 7a and 7b to be joined.
- a clip 8 can be pushed and fixed between the extension 1 and the end face of the cap 6.
- the arrangement of a magnet 9 in the cap 6 becomes difficult to lift
