Clamping rail for writing or drawing boards

The innovation concerns a clamping rail for a writing and/or drawing board, whereby the clamping rail is

clamping springs to the plate body. The clamping rail is also designed in such a way that it can accommodate a writing instrument equipped with a clip.

Various solutions have already become known from the state of the art. For example, in the German utility model No. 83 24 385, a clamping rail for a writing and/or drawing board is described, in which the clamping rail is equipped with a quiver-like area. This quiver-like area has the shape of a slotted tube and is used to hold a writing pen.

The solution described in this older utility model has the disadvantage that a pen provided with a clip protrudes laterally over the edge of the plate when the clip is attached to the quiver wall.

Another solution has become known through the German design patent 6MR1268 -AG Montabaur-. In this solution, the pen equipped with a clip is inserted into a groove formed in the top of a clamping rail, with the clip being inserted into an opening provided in the front of the clamping rail.

This solution has the disadvantage that only clips with certain dimensions can be inserted and that the writing instrument - as also discussed in the design according to DE utility model no. 82 24 385 - protrudes to the side.

The invention is based on the object of creating a clamping rail for writing and/or drawing boards,

in which the pen holder is designed in such a way that a writing instrument can be easily attached without it protruding beyond the edge of the writing and/or drawing board.

This task is solved by forming a trough-like depression with at least one opening into the upper longitudinal edge of the clamping rail.

Further features related to the invention can be found in the subclaims.

The present invention also allows the attachment of pens that have a projection on their shaft that serves as a support for a band-like flat clip. This clip rests on the projection under slight pre-tension. To ensure that this projection does not interfere after the pen has been inserted into the trough-like depression, a further depression is provided in the base of the depression. This additional depression can of course also be designed as a cutout.
Preferably, the clamping rail is equipped with two openings for inserting the clip in order to make the writing and/or drawing board equally usable for right-handed and left-handed people.

This solution is also ideal for attaching advertising prints, as the inserted pen does not cover the top of the clamping rail.

An embodiment of the invention is described below and illustrated by the drawings. It shows:

Figure 1 is a perspective view of a writing tablet;

Figure 2 shows the view of the top of the clamping rail;

Figure 3 shows the view of a longitudinal edge;

Figure 4 shows the side view of the clamping rail.

The clamping rail (1) is mounted in the area of the upper transverse edge of a writing and/or drawing board (10) and clamps the writing or drawing sheet on it. The required clamping force is generated by leaf springs (not shown here). The trough-like depression (3) into which the writing pen (6) can be inserted is provided in the longitudinal edge (8) facing away from the user. The writing pen is inserted into the trough-like depression in such a way that the clip can be received by the opening (2a) or (2b). Moving the writing pen (6) sideways causes the clip to grip the bottom surface of the trough-like depression and thus prevent the writing pen from falling out.
Since there are also pens with a projection on the shaft surface that supports a flat band-like clip, a solution was needed that would prevent the pen from rocking after it has been inserted into the trough-like recess. To do this, a further recess (4) was formed in the trough-like recess (3). This recess (4) can also be designed as a cutout. It is also so long that it does not matter from which side the pen (6) is inserted into the recess (3).
The upper side (5) of the clamping rail (1) is deliberately kept large in order to provide sufficient space for advertising prints.

The clamping rail (1) rests with its underside (9) on the writing surface (10), where it is held by means of clamping springs (not shown here).

As can be seen from Figure 4, the clamping rail (1) is equipped with an inclined surface (7) running from the support surface (9) to the front longitudinal edge, which makes it easier to lift the clamping rail (1) in order to slide a writing or drawing sheet underneath.
