Description

SPECIFICATION Wall calendar The present invention relates to a wall calendar of the kind comprising a plurality of superimposed calendar sheets each provided in the vicinity of the upper longitudinal edge of the calendar with a plurality of holes1 registering from one sheet to the next, for receiving a binding in such a way that the sheets can be turned back individually, and having a suspension device.

The problem in wall calendars of this kind is the way and method of suspension which has to be adapted to make provision for simple turning over of the individual calendar sheets during any change, for example to a new month. In the case of calendars which are provided with sheets stacked on one another, and adapted to be turned over, in general a so-called wire-O or a twin-wire or a skip binding is most frequently used, whilst somewhat less frequently spiral or plastic-effect bindings are employed. In all these types of binding the calendar sheets and, if used, also the rear panel have registering holes disposed side-by-side at a regular spacing over the whole width or, as in the case of the skip binding only a part section, for reception of the appropriate binding.

In the case of wire-O or twin-wire bindings it is usual to interrupt this binding in the longitudinal centre of the wall calendar and to insert into the two opposed ends of this binding area a clip which is curved in the middle and has rectilinear end sections, the upper edge of the calendar being provided with a thumb-size groove which accommodates the curved area of the clip during the turning over of the calendar sheets. Of disadvantage here is in the first place the fact that the thumb-size groove must always be regarded as constituting a foreign element in the shaping of the calendar and thus provide an intrusion, as well as being a handicap. In addition the introduction of this clip represents an additional operating step during the mechanical binding of wall calendars.

There are also wall calendars with this type of binding which have an additional suspension strip used for advertising, this strip being provided with a suspension eye. This type of suspension however will interfere with the turning over of the calendar sheets because this action would mask the suspension strip and for this reason the sheets must be torn off from such calendars which cannot be done without impairing the idea and purpose of the binding referred to above.

Further it has been proposed to provide the calendar sheets, and if used also the rear panel, beneath the holes for the binding with an additional central suspension hole in the form of a 'through' hole. But this also, even if small, like the thumb-size groove referred to above blemishes any single image carried by the calendar sheet, so that this suspension hole is also a defect. In addition this type of suspension has the further disadvantage that the machine for making the binding has to be equipped with an additional punching tool, which requires an additional retention means in the punching equipment, and the punching tool used has to be renewed as a whole.

There has been a further attempt to implement the suspension of a wall calendar with the bindings referred to above by threading a cord, string or the like through the central hole of those provided for reception of the binding and knotting it. This method of providing for suspension is not practicable mechanically, because the threading in and knotting has to be done by hand. In binding more than 100 and certainly in the case of more than 1000 or even 10000 wall calendars this is ridiculous because of the time taken.

The object of the present invention is to provide a wallcalendar of the type set forth above which avoids these drawbacks, that is to say has a suspension means which caters for convenient machine fabrication even for very big numbers.

This object is met by the provision of a wall calendar of the kind set forth above in which one or more of the binding-receiving holes in each calendar sheet on the longitudinal centre line of the calendar and/or at equal spacing therefrom is or are enlarged by an integral suspension operation perpendicular to the upper longitudinal edge of the calendar.

Thus in the present invention a wall calendar is provided in which the suspension aperture or apertures is or are combined in advantageous fashion with the central hole and/or with two holes equally spaced from the longitudinal centre of the calendar into a single opening. In the light of this combination the suspension hole does not necessarily have to be particularly large to accommodate a hanging nail or the like so that it projects but little beyond the lower edge of the binding holes and consequently it will not interfere with any image portrayed on the calendar sheet and thus be detrimental. A further and very important advantage resides in the fact that this type of suspension will also cater for mechanical production on a large scale, because to provide this or these enlarged openings only one or more of the stamping bits has to be changed in the stamping tool.

It will be understood that this kind of suspension device construction can be provided for all the types of binding referred to above, that is to say also for so-called skip bindings.

Further details and constructions in accordance with the invention are to be found in the ensuing description and explanation of the invention in reference to embodiments illustrated in the drawings. In these drawings: Figure 1 is a perspective illustration of a wall calendar with a wire-O or twin-wire binding, Figures 2 and 3 are diagrammatic and part illustrations of a wall calendar having a skip binding, and Figure 4 is a detail representing the part encircled at IV in Figures 1 to 3 and illustrating a suspension device in accordance with the invention.

The wall calendars 11 illustrated in the drawings comprise a plurality, for example twelve calendar sheets 12, a cover sheet 13 and a rear panel 14, all of which are connected to one another so that they can be individually turned over.

To provide for this turnover procedure the wall calendar 11 of Figure 1 is provided in the area of its upper edge 16 with a wire-O or twin-wire binding 17 which is threaded through holes 18 in the calendar sheet 12, the cover sheet 13 and the rear panel 14.

The holes 18 of these calendar parts 12 to 14 are arranged in register and in this embodiment are at a regular spacing over the complete width of the calendar. The distribution of these holes 18 over the width of the calendar 11 involves the arrangement of one hole 18m for a suspension device 26 in the area of the longitudinal central plane 19 of the calendar.

In the examples illustrated in Figures 2 and 3 the wall calendar, 11' and 11" respectively, is provided with a so-called skip binding, 17' and 17" respectively, that is to say the individual turns of the bindings 17' are not, as in the case of the twin-wire binding 17, uniformly distributed over the full width of the calendar but the turns 21' are combined in an odd or even number to form sets 22 of turns.

In Figure 2 an odd number of sets of turns 22, and in the case of Figure 3 an even number of such sets, are arranged at regular distances over the width of the calendar 11' and 11" respectively. The central set 22m of turns in Figure 2 is arranged in the longitudinal medial plane 19 in such a way that the central turn 21 'm is disposed in the longitudinal medial plane 19. The same applies to the holes 18' and the hole 1 8'm for the suspension device 26 of the wall calendar parts 12 to 14 for suspension of the skip binding 17'. In the embodiment illustrated in Figure 2 three sets of turns 22 are for example provided, each comprising five turns 21'.

The embodiment illustrated in Figure 3 is advantageously used in the case of a relatively wide calendar because there is provided at each of the two sides of the longitudinal medial plane 19 two sets 22 of turns for example each of five turns 21'.

Thus for the suspension device 26' there are two holes 18"1 and 18"rwhich in each case are the central hole for the outer set of turns 22 and are at the same distance from the longitudinal medial plane 19.

Figure 4 is a larger illustration of the suspension device 26 or 26' in accordance with the invention, this being implemented by one or two enlarged openings to receive a suspension pin, nail or the like.

The suspension opening 26, 26' is constituted by the combination of the appropriate holes 18m and 18'm or 18"1 and 18"rwith a suspension aperture 27. In other words the hole 18m, 18'm, 18"1, 18"r concerned and the suspension aperture 27 are combined to a single enlarged suspension opening 26, 26' so as to run directly into one another. In the embodiment illustrated the holes 18, 18', including the holes 18m, 18'm, 18"l, 18"rforthe suspension openings 26, 26' are of rectangular shape, whilst the suspension aperture 27, 27' may for example be circular, the diameter being equal to the width of the hole 18, 18', and adjoins the latter aproximately at the longitudinal medial axis. The enlarged suspension opening 26, 26' may however also be somewhat of more rectangular or square basic structure and provided with a curved bottom edge. What is important is that the enlarged suspension opening 26, 26' is visually not substantially larger than one hole and thus does not obtrude into the particular image provided on the relevant calendar sheet. The integral combination of the binding hole 18, 18' with the suspension aperture 27, 27' to form an enlarged suspension opening 26, 26' hasthefurtheradvan- tage that this can be made by a single stamping tool.

It will be understood that the features of the invention can be implemented not only in combination with the wire-O and twin-wire or skip bindings described and illustrated in the drawings but also in the case of a spiral or a plastic effect binding.
