Description

Oct. 30, 1962 P. A. s. PETERSEN WRITING INSTRUMENT Filed Dec. 15, 1959 Denmark Filed Dec. 15, 1959, Ser. No. 859,629 1 Claim. (Cl. 40334) The invention relates to a writing instrument of the type having a holder containing writing elements or units such as ink cartridges, tubes with paste, pencil lead magazines or the like. The said writing units or elements may be fixed or movable.
Hitherto, the holder for such writing instruments has been made of one or more hollow cylindrical bodies into the inner cavity of which the writing units could be introduced and moved freely. In recent years, writing instruments have been made with the rear half consisting of transparent containers filled with a non-volatile liquid with movable bodies, whereby the room left for the writing units is limited to the front half of the instrument.
It is an object of the present invention to provide a writing instrument in which the writing units can be arranged behind such cavities as are filled with a liquid or with other eye-catching parts, e.g. letters or pictures, while on the other side these can be extended freely down over the bottom parts of the writing instrument, bypassing the writing units disposed in that section. In this way there is provided a writing instrument the writing units of which have their full capacity.
In accordance with the invention, the holder consists in part or throughout its length of two or more sectorshaped parts freely enclosing the writing units, the said sector-shaped parts being connected with each other along their abutting surfaces and/or at their ends, for example by means of glue or special retaining and/or assembly means.
The combined sector-shaped parts thus form a cover or barrel in the inner cavity of which the writing units may extend freely throughout the entire length of the instrument. The instrument can be assembled by joining the sector-shaped parts around the writing units, whereby a quicker and more reliable assembly of the holder parts is obtained than in cases where annular or cylindrical parts have to be assembled.
In accordance with the invention at least one sector may be composed of shells arranged one outside the other, the outer shell being translucent, preferably transparent, whereas there are surfaces behind it with letters, pictures or other such material or intelligence. The said surfaces will be safely protected from wear, and if the outer surface of the outer shell is curved, it will produce an optical enlargement.
In accordance with the invention, it is furthermore possible to provide a cavity between the outer translucent or transparent shell and the inner shell or shells, which cavity may serve to accommodate movable bodies. The said cavity may thus extend practically throughout the entire length of the writing instrument, and the said instrument may be provided with a plurality of such cavities in the different sector parts.
The drawing shows a writing instrument in accordance with one embodiment of the invention.
3 ,000,607 Patented Oct. 30, 1962 In the drawing:
FIGURE 1 is a diametral section through a pencil, and
FIGURE 2 is a section on the line II1I of FIGURE 1.
As will appear from FIGURE 2, the pencil holder is composed of four sector-shaped parts, two of which, i.e. the parts 1 and 2, are solid, whereas the two other sector-shaped parts are divided into three parts, each consisting of two shells, one lying outside the other. All the sector-shaped parts may be glued together along their abutting surfaces. The left-hand sector-shaped part consists of an inner shell 3, see FIGURE 2, which is opaque and carries a picture layer 5, whereas the outer shell 4 consists of a transparent material which produces an optical enlargement of the picture surface.
The right-hand sector part consists of an opaque shell 6 covered by an outer shell 7 of transparent material and leaving a narrow rectangular space 8 between them, the said hollow space extending in the entire length of the holder. The front wall and rear wall of the said space 8 may be provided with pictures or other communication surfaces and one or more movable bodies B in the space 8 may be freely movable or be mechanically connected with the push-button 9 which moves the writing units of the pencil, or the body or bodies may be assumed to be moved by other means operable from outside such as the clip 10 of the pencil, the said clip being in the embodiment disclosed introduced into a hole 11 in the part 2 directly before the holder is assembled.
It will be appreciated that the sector-shaped parts may be provided in a number and be of a width to suit requirements.
The writing elements of the pencil constitute, apart from the push-button 9, a combined unit which can be inserted into the holder by means of threads 12.
What is claimed is:
A writing instrument comprising a holder and writing means; said holder comprising diametrically opposed solid sectors, intermediate sectors extending between said solid sectors and constituting therewith a substantially cylindrical body defining a central bore in which said writing means is displaceably accommodated, and means for connecting said sectors together, at least one of said intermediate sectors comprising generally concentric inner and outer shells of which said inner shell is opaque and said outer shell is of a material which may be seen through whereby intelligence positioned inwardly of the outer shell and outwardly of the inner shell may be observed, means for displacing said writing means in said bore between operative and inoperative positions and indicia means slidably supported between said shells and coupled to the last said means for being displaced thereby whereby adjustment of the position of the indicia means relative to the shells can be obtained.
