EP0359142B1 - Case for calendar sheets or the like - Google Patents

Description

The invention relates to a housing according to the preamble of the main claim for a stack of sheets of the same dimensions as calendar sheets, diagrams, graphic representations, photos, in particular to a smaller housing.

Such housings are known which have a flat, with a lid closable, formed as a frame rectangular receptacle for the leaves, on which a parallel to two rectangular sides slide bar is slidably arranged, on the longitudinal direction of which a frame-shaped slide is slidable. The slide bar and slide can be moved at right angles to each other in the free field of this frame.

EP-A3-171 490 describes a housing for calendar pages, in which a relatively narrow slide bar is provided, which is mounted on the end of the housing and carries a frame-shaped slide. With this housing, it can happen that the slide bar is tilted and jammed, still there may be difficulties with disassembling and assembling the housing.

GB-A-110,191 shows a calendar with a frame-like housing, on the outer edges of which a slide bar is mounted, which carries a frame-like slide. Here, too, there is a risk of the slide bar jamming or jamming; in addition, it can easily fall off the calendar.

The invention has for its object to provide a housing of the type mentioned, which avoids the disadvantages of the prior art with a simple structure and simple, inexpensive to manufacture and in particular enables a stable mounting of the slide bar and easy assembly and disassembly of the housing.

According to the invention the object is achieved by the features of the main claim, the subclaims show further advantageous embodiments of the invention.

Such a double bar is relatively wide and thus gives a torsional stiffness in a groove guide in the lateral region of the frame, particularly in the case of thin slide bars, which prevents the slide bar from bending. This improves the movement of the slide bar by hand.

In a preferred embodiment, the slide bar is laterally extended by tongues protruding in its plane, in order to thereby improve its guidance in the lateral grooves of the frame.

In a further preferred embodiment, the frame, which holds the slide bar and the slide, is closed on the back by means of a preferably detachable cover.

To fix this cover to the frame, a locking tongue is preferably provided on the cover, which engages behind a locking bar protruding from the frame. When this latch tongue moves towards the center of the cover, the cover can be detached from the frame.

Such a housing can be set up on a surface by means of a pivotable stand which is articulated on the back.

If, however, this housing is to adhere to a surface, then a holding plate is preferably provided which comprises the cover and the frame, which is held in a clamping manner and has a holding adhesive layer, a magnet or the like on the rear.

Such a housing for calendar sheets or the like is a very practical object, which can have advertising areas on the frame side of the slide bar, onto which an advertisement can be printed or glued and thus serves as an advertising medium.

(10) denotes a housing in which sheets, such as calendar sheets, photos and other representations, can be inserted individually or as a stack.

The housing (10) shows a front frame (11) with an open area (12) in which a double slide bar (13) with slide (14) sliding thereon and also the illustrations on the inside are visible.

The frame (11) has rear side strips (15) which on the one hand stabilize the front frame (11) and on the other hand form the space for receiving the inserted sheets.

The slide bar (13) is slidably mounted in a groove (16) which is arranged on two opposite side bars (15) of the frame (11). For this purpose, the thin slide bar (13) is made of transparent plastic in the form of a plate. It has an upper narrower bar (13 a) and a wider lower bar (13 b), which are separated from one another by a slot (13 c), but are connected to one another at the ends.

This slide bar (13) is relatively rigid due to its width and shows guide tongues (13 d) projecting on one side in the same plane, which lie in the groove (16) and offer the slide bar (13) an additional guide area. For this purpose, the lateral guide tongues (13 d) are elongated in the direction of displacement. This slide bar (13) with guide tongues (13 d) can be punched out of a plate or produced by injection molding.

The slide bar (13) carries a displaceable slide (14), the middle free field of which, for example, makes numbers of a calendar sheet visible. This slide (14) comprises only the upper bar (13 a) on the front and thus leaves the bar (13 b) free for advertising or the like.

On two opposite side strips (15), narrow locking strips (17, 18) are fastened at a distance from the frame, by means of which a cover (20) bordering on the rear is fixed.

This cover has a groove (21) on one side into which a locking bar (tongue) (18) is bordered. On the opposite side is a bolt tongue (22) slidably mounted, which can be moved behind the other locking bar (17) to fix the lid (20) on the side bars (15) of the frame (11) and is held in the lid (20) by means of tongue and groove, preferably the lid (20) the spring and the locking tongue (22) contains the grooves (see. Fig. 5).

For this purpose, the displaceable locking tongue (22) for fixing the cover (20), preferably in the frame (11), has further lateral grooves (24) into which springs (25) projecting from the frame.

The cover (20) is further equipped with boundary strips (29) protruding rectangularly in the edge area, into which the leaves are inserted.

On the back of the cover (20) there is a stand (23) which can be pivoted outwards and which allows the housing (10) to be set up.

In order to fasten the housing to a surface, a holding plate (26), which is provided with projecting retaining strips, is provided, which includes the cover (20) or the frame (11) in such a way that there is a certain clamping between the parts.

On the back of this holding plate (26) a holding adhesive layer (27) is attached, which is initially covered in a known manner by a removable film (28).

Instead of an adhesive layer, a magnet (not shown) can also be attached to the holding plate (26).

The holding plate (26) has a recess so that the user can release the locking tongue (22) with his finger or setting the frame (11) on the lid (20) can move.

In addition to the front of the housing, advertising surfaces can also be provided on the slide bar (13).
