APPARATUS FOR SECURED ACCOMMODATION OF DRAWING UTENSILS

Abstract

An apparatus for securely accommodating drawing utensils receives one set square between two plates of a base receptacle. the plates are arranged and connected to one another such that a compartment for the set square spans between them. The compartment comprises on one side an insertion opening for the set square and, in a plate, an insertion slot for a grip piece of the set square The insertion slot originates from the insertion opening and is parallel to the insertion direction. An additional cover plate is above the triangular plate, having an insertion slot of the base receptacle for a large set square, spanning an additional compartment for drawing utensils. The cover plate is connected to the base receptacle while spanning the additional compartment. A groove-shaped pin receptacle is between the hypotenuse of the base receptacle and the nearer cover plate, and accommodates a drawing pencil clampingly on the flank side. The pin receptacle comprises a T-groove which extends longitudinally and receives a two-limbed clamping spring, which forms a pencil holder for a drawing pencil and protrudes from a guide plate inserted into the T-groove.

[0020] FIG. 1 a plan view of an apparatus according to the invention,

[0021] FIG. 2 the apparatus of FIG. 1 in section according to line II-II,

[0022] FIG. 3 an enlarged section of FIG. 1 with a preferred pin receptacle, and

[0023] FIG. 4 the pin receptacle of FIG. 3 in section according to line IV-IV.

WAYS OF CARRYING OUT THE INVENTION

[0024] The apparatus 1 for securely accommodating drawing utensils receives a large set square 5 between two plates 7, 8 of a base receptacle 4, the plates 7, 8 being arranged relative to one another and connected to one another in such a way that a compartment for the set square 5 is spanned between them, the compartment having on one side an insertion opening E2 for the set square 5 and, in the plate 7, an insertion slot for a grip piece 6 of the set square 5, the insertion slot originating from the insertion opening E2 and being parallel to the insertion direction. Above the triangular plate 7 of the base receptacle 4 for the large set square 5, which has the insertion slot, at least one further cover plate 3 is arranged which spans an additional compartment for additional drawing utensils, a small set square 2, and which is connected to the base receptacle 4 while spanning the additional compartment. The triangular cover plate 3 of the additional receptacle is inserted between the catheti of the base receptacle 4.

[0025] A small set square 2 is inserted into the apparatus 1 at the top left. A lateral insertion slot E1 under the uppermost cover plate 3 enables the set square 2 to be removed with a sliding movement to the left. This uppermost cover plate 3 is arranged at a distance from a base receptacle 4. The receptacle for the small set square 2 is bounded at the bottom by the base receptacle 4 for a large set square 5 and at the top by the uppermost cover plate 3. Along two of the three sides of the cover plate 3, the latter is connected to the base receptacle 4. In the area of the third side there is an insertion slot E1 for the small set square 2.

[0026] At the top right is a name field NAME, a printed frame in which a name can be entered with a permanent drawing pencil 13, or in which a name tag can be inserted.

[0027] Below this, in the direction of the hypotenuse of the triangular apparatus, in the centre of the apparatus 1, the insertion slot E2 for the grip piece of the large set square 5 can be seen in the base receptacle, which is inserted from the right into the base receptacle 4 of the apparatus. With a sliding movement to the right, the large triangle 5 can be removed with its grip piece 6 or it can be pushed back into the base receptacle 4, which is bounded at the top by the middle plate 7 and at the bottom by a base plate 8. Along two of the three sides, the middle plate 7 and the base plate 8 are connected to each other. In the area of the third side, the insertion slot E2 for the large set square 5 is provided.

[0028] In the middle of the apparatus, to the left of the insertion slot E3 or the grip piece 6, an eraser 9 can be clamped between the cover plate 3 of the small set square 2 and a cover plate 10 of a ruler 11 and inserted into a receptacle. Clamping knobs 14 protrude from the cover plate 3 towards the compartment and clamp the eraser 9.

[0029] The cover plate 10 of the ruler 11 is provided in the centre, below the receiving compartment, as seen in the direction of the hypotenuse of the apparatus. The ruler 11 is removed or inserted into the apparatus via an insertion slot E3 which is open to the left. With a sliding movement to the left, the ruler 11 can be removed or pushed in again to the right. Along two or three sides of the cover plate 10, the latter is connected to the base receptacle 4. In the area of the fourth, possibly also the third side, an insertion slot is provided for the ruler 11, which could be pushed through its receptacle.

[0030] Below this are two groove-shaped pencil holders 12 for drawing pens 13. By tilting the drawing pens 13 as a result of pressing the pencil tip against the middle plate 7, each drawing pencil 13 can be lifted out of the recess. Drawing pencils 13 are held securely in the respective pencil holder 12 by means of preferably resilient nubs 14 arranged along the longitudinal sides of the receptacles between which the drawing pencils 13 can be inserted and projecting towards the receptacle. The drawing pencils 13 can have a thickness, a cross-sectional diameter of 2 to 14 mm.

[0031] The pencil holder 12 has a T-groove 16 extending in the longitudinal direction of the pencil holder, into which at least one two-limbed clamping spring 18 forming a holder 15 for a drawing pencil 13 and projecting from a guide plate 17 inserted into the T-groove 16 is inserted to receive the drawing pencil 13. The holders 15 are guided in the T-groove 16 so as to be displaceable in the longitudinal direction of the pen receptacle in displacement sections, the displacement sections being bounded by latching elements, the clamping knobs 14.

[0032] To the right of this is a receptacle 19 for a pencil sharpener 20 (FIG. 1). A container 21 is inserted into the holder, which carries the pencil sharpener 20 on the inside of the container at the front. This allows a drawing pencil 13 to be sharpened when the container 21 is inserted into the receptacle 19 and the sharpening waste is stored in the container until it is disposed of.

[0033] A ruler scale from 0 to 30 cm is attached (printed) at the lower end in the area of the hypotenuse of the apparatus. Graduated in mm-steps, each cm-point is provided with a digit. Thus, a full-fledged “ruler” exists here. The scale line assigned to the 0 point of the scale is equipped with an attachment point 0 for a compass.
