Description: Scream bm&ppe

&'^&bgr; The invention relates to a writing case with the features specified in the preamble of claim 1. The term "writing case" covers all types of cases, such as college, conference, file, pencil cases, ring binders in a wide variety of formats and with various inserts, such as calendars, alphabetical registers, letter and check card pockets, etc. All of these items have in common a multi-layered cover, preferably made of an outer cover layer, a reinforcing cardboard insert and an inner layer, and at least one insertion loop for a writing instrument, preferably attached to an edge area of the cover. The latter is thus held on the writing case within easy reach and ready for use at any time.

A problem with holding writing instruments by

The reason for such insertion loops is that the external diameters of the various writing instruments often vary greatly. A slim pencil should be able to be held just as securely as, for example, a thick multi-coloured ballpoint pen. To ensure this, insertion loops made of an elastically stretchable material - for example, a flat rubber cord - are known.

Such insertion loops adapt to the respective pen diameter, but are not satisfactory in terms of their susceptibility to wear and their overall aesthetic impression. The elastic cord can dissolve in its fabric structure, fray and finally tear if the writing instrument is frequently inserted and removed, especially if it is subjected to additional stress by its retaining clips. If an elastic cord as a circular insertion loop already impairs the overall aesthetic impression of a dignified design of such a writing case that corresponds to the prevailing taste of the time, for example in artificial or natural leather, a worn, frayed loop is so disruptive that it often seems impossible to continue using the case.

t-a further disadvantage of variable diameter loops in writing folders according to the state of the art is that the holding force of the loop is strongly dependent on its degree of stretch and thus on the diameter of the inserted writing instrument.

Based on the above-mentioned disadvantages, the invention is based on the task of improving the described insertion loops on writing cases and the like in terms of their service life and their overall aesthetic impression. The solution to this task is specified in the characterizing features of claim 1. Accordingly, a material that is essentially not or only slightly stretchable is used for the insertion loop. This has the advantage that the same material can be used for the insertion loop as for the outer cover or inner side of the cover of the writing case. So that the loop diameter can adapt to the diameter of the respective writing case, the insertion loop has a

ar, a fixed end fixed to the cover and a movable free end which is acted upon by an elastically stretchable drawstring running inside the cover - for example in the form of a flat rubber cord. If a very thick writing instrument is now inserted into the insertion loop, the free end gives way so that the loop expands. The elastic action by means of the drawstring ensures that the writing instrument is held reliably in place regardless of its diameter.

Advantageous embodiments of the subject matter of the invention are specified in the subclaims.

The drawstring can be held in place in a simple manner by fixing the end of the drawstring facing away from the free end of the insertion loop to the cover. This can be done in particular together with the sewing or laminating of the individual layers of the cover against each other in one production step.

According to claim 3, the free end of the insertion loop is guided through an elongated hole arranged in the width direction in the area of its fixed end. The elongated hole can also be designed as a simple slot. This design ensures that the free end of the insertion loop is guided cleanly. This also prevents wear on the side edges of the loop. Finally, the fixation of the fixed end of the insertion loop - for example in the form of a seam or gluing to the cover - is relieved of tensile forces.

The overall impression can be further improved as the insertion loop designed in this way is indistinguishable from conventional, non-stretchable loops. The measure specified in claim 5 also results in a functional advantage. The stepped design of the narrowing between the middle area and the free end of the insertion loop , in conjunction with the adjustment of the elongated hole width to the width of the free end of the holding loop, creates a type of stop between the stepped edges of the narrowing and the sections of the fixed end of the loop on both sides in extension of the elongated hole. This stop ensures that even when the writing instrument is removed, the insertion loop always has a small, open minimum diameter, which makes reinserting the writing instrument much easier. This measure can also be used to place the tension band under a defined pre-tension, which increases the holding force, particularly in writing instruments with a small shaft diameter.

The measure specified in claim 7 has the advantage that the drawstring is protected from external influences and is arranged with a maximum possible length - namely the distance between the outer side edge of the cover and its spine. The ratio of the change in length of the drawstring to its absolute length is thus optimally small, whereby the drawstring is effectively protected against wear and the holding force it exerts, which is essentially generated by its pre-tension, is largely independent of the shaft diameter of the inserted writing instrument.

Advantages in both aesthetic and functional respects are achieved by designing the writing folder according to the characterizing features of claim 8* By the

A channel for the drawstring is formed in the cover by means of interlayers, which ensures that it is guided cleanly. In particular in connection with the characterizing part of claim 9, the cover has

Area where the surface of the cover may become worn over time.

The invention is explained in more detail in an exemplary embodiment using the attached figures. They show:

Fig. 4 a perspective, exploded view of the cover in the form of an exploded view and

Fig. 5 a vertical section through the cover along the straight line V-V according to Fig. 1.

Fig. 1 shows the open cover (1) of a writing folder (2), with a writing pad (C4) attached to the right half of the inside (5). In the area of the side outer edge (5) opposite the pad (4) there is an insertion loop (6) for a writing instrument (not shown). Regarding the structure and function of this insertion loop (6), please refer to the description of Figs. 2 and 3.

As can be seen from Figures 1 and 5, the cover (1) is made up of several layers, consisting of the outer cover layer (7), the reinforcing insert cardboard (8) and the inner layer (9). The back layer (7) and inner layer (9) are preferably made of natural or artificial leather. Of the cover layer (7), only the folded edge areas (10) can be ^seen in Figure 1, which comprise the insert cardboard and the inner layer (9). The individual layers are fixed ^to one another by means of the upper (11) and lower edges (12) of the cover ( ¹ ).

The special design of the insertion loop (6)

can be seen from Fig. 2 and 3. The loop itself is formed by an essentially rectangular tab (14) (Fig. 3) which is made of the same material as the cover layer (7) or inner layer (9). The fixed end (14) is sewn seamlessly to the outer edge (15) with the folded-over edge region (10) of the cover layer (7) and is thus fixed. The middle region (15) of the tab (13) forms the actual insertion loop (6). The free end (16) opposite the fixed end (14) is connected to the tab (13) by an elongated hole (18) arranged in the area of the fixed end (14) in the width direction (17) and by a further elongated hole (18 ¹ ) aligned with the elongated hole (18). d!sr inner layer (9) and with the elastically stretchable tension band (19) made of flat

QO rubber cord by means of a seam (30). As can be seen from the dashed part of Fig. 1 and Fig. 5, this tension band (19) runs under a certain pre-tension and the free end (16* of the loop (6) inside the cover U> between the insert cardboard (8) and the inner layer (9). It is connected to the end (20) of its loading for

·»·» »r &bgr; "pi

the free end (16) of the insertion loop (6) is attached to the fixed end (21) in the area of the spine (22) of the cover (1). On both sides next to the long edges (23) of the drawstring (19) there are further intermediate

Cardboard pieces (24) arranged with their

facing each other, parallel to the long edges (23) of the drawstring (19) side edges (25) in the cover (1) form a channel (26) for the drawstring (19) (Fig. 4,5),

As can best be seen in Fig. 2, the free end (16) of the insertion loop (6) is narrowed in steps compared to its mid-section (15), whereby the width of the slot (18) essentially corresponds to the

Width of the free end (16).

The sections (27) of the insertion loop (6) on both sides extending from the elongated hole (18) serve, in conjunction with the front step edges (28), as a stop during the contraction movement of the insertion loop (6) caused by the elastically pre-tensioned tension band (19). As shown in Fig. 1, this always has a minimum diameter (29).

If a writing instrument that is significantly thicker than this diameter is inserted into the insertion loop (6), the free end (16) pulls through the slot (18) while stretching the tension band (19), whereby the diameter of the insertion loop (6) corresponds to the

gO of the writing instrument. The elastic loading by means of the tension band (19) ensures that the writing instrument is held reliably.

It should be noted that the tab (13) for the gg insertion loop (6) is preferably made of the same material as the cover (7) or
