Description

The present invention relates to a device for receiving documents.

Devices for receiving documents are known in the art and are usually used in the form of document sleeves application, for example, maintenance instructions, maintenance lists, goods collection notes, application notes, instructions for use, information boards and the like visible from the outside but still protected behind a transparent cover.

The structure of such devices for receiving documents usually consists of stacked plastic films with marginal connections of these plastic films to form at least one receiving area for documents. The front side of the device for receiving documents is preferably transparent and, in spite of the protective function, provides a clear view of the respective documents.

Sometimes such devices are magnetically releasably attached to metallic surfaces. For this purpose, usually the back of the device for receiving documents is magnetically coated. This type of releasable attachment of the device allows a high degree of flexibility, especially in industrial applications.

Such device for receiving documents thus meet the requirements to protect documents from dust, oil, dirt, water and other particles and liquids while visibility of the document front page and on the other hand allow easy and re-releasable attachment to ferro- or ferrimagnetischen surfaces (hereinafter referred to as magnetic surfaces).

Although such devices meet the aforementioned requirements for the protected recording of documents and their attachment to ferromagnetic or ferrimagnetic or magnetic surfaces, there is a need for improvement for special applications. Thus, especially on dirty ferromagnetic or ferrimagnetic or magnetic surfaces adhesion problems exist, which can lead to difficulties in the assembly of the devices with documents, for example in industrial environments in which a one-handed operation is required for safety reasons and therefore slippage of the device during the assembly process should be avoided as possible. Also, stresses on the connection, for example due to vibrations, may lead to the device slipping or even falling off.

Against this background, it is an object of the present invention to provide a device for recording documents which at least partially overcomes the disadvantages of known magnetic devices for recording documents, and in particular an improved adhesion of such devices for recording documents to ferro- or reached ferrimagnetischen or magnetic adhering surfaces.

These and other objects are achieved by a device according to the invention for receiving documents according to claim 1. Preferred embodiments are subject of the dependent claims.

Accordingly, the device according to the invention for receiving documents has at least a first document area, the first document area having at least two substantially flat plastic films which are peripherally, at least partially cohesively, interconnected, so that between the two plastic films a receiving area for documents is formed, and wherein at least one of the plastic films is arranged transparent and at the front of the device. The device has at least one magnetic element arranged on the rear side of the device for the detachable attachment of the device to ferromagnetic or ferrimagnetic or magnetically adhering surfaces.

According to the invention, the device for receiving documents has a plastic friction layer that increases at least the static friction, which covers the magnetic element so that, when the device is attached to a ferromagnetic or ferrimagnetic surface, it is between the magnetic element and the surface lie comes.

With the arrangement of magnetic element (s) "behind" a stiction and / or the sliding friction increasing plastic layer in the context of the present invention can be specifically influenced on the adhesion of the device according to the invention especially on difficult surfaces that are, for example, oil contaminated, taken and so a secure hold and reduced the risk of slippage.

Document areas within the meaning of the present invention are the areas of a device for receiving documents, in which a receiving area for documents is formed by two marginally at least partially cohesively interconnected superimposed films. Document areas within the meaning of the present invention can also be understood as a document envelope, document pocket, document folder or document inserts.

For the purposes of the present invention, the front side of the device for receiving documents means the side of the device through which the documents arranged or inserted in the receiving area are visible or can be viewed by the viewer when the device is attached. The back side is accordingly the side opposite the front side of the device, preferably the side with which the device is fastened to ferromagnetic or ferrimagnetic or magnetic surfaces.

In the context of the present invention, ferro- or ferrimagnetic or magnetic surfaces mean all surfaces on which permanent magnets can be releasably attached again. Examples of surfaces in the context of the present invention are metallic surfaces of iron, cobalt or nickel or their alloys, such as. As steel shelves, steel beams, steel cabinets, steel doors, steel plates, containers, boxes and mesh boxes made of metal, especially steel or metal sheet and the like.

In the context of the present invention, a plastic layer which increases the static friction is understood as meaning a plastic layer which increases the static friction and / or the sliding friction between said plastic layer and a preferably metallic surface in contact therewith. The static friction can also be stated as friction coefficient or friction coefficient. In another Embodiment of the device according to the invention, a head portion is provided, which is arranged above the first document area and wherein the at least one magnetic element is arranged at the head area.

For the purposes of the present invention, the term "head area" is understood to mean a preferably strip-shaped area on an upper side of the device, so that the device adjoins a ferromagnetic or ferrimagnetic or magnetic surface of low vertical extent, such as, for example, a shelf or even a tube, frame or Grid struts can be attached hanging.

In a further embodiment of the device according to the invention, the plastic friction increasing layer is formed by a plastic film with which the magnetic element is coated on the back side. In particular, it is provided in this embodiment that the magnetic element, from the viewpoint of the ferromagnetic or ferrimagnetic or magnetic adhesive surface behind the static friction increasing plastic film is arranged, so for example in a pocket between the back plastic film of the document area and the static friction-increasing film, which rests directly on the ferromagnetic or ferrimagnetic or magnetic adhesive surface.

In a further embodiment of the device according to the invention for receiving documents, the plastic film which increases the stiction is at least partially bonded cohesively to the device, at least on the edge side.

In the edge-side bonding of the stiction-increasing plastic film with the device, there is a particularly favorable way of producing the device according to the invention, since the "film bundle" forming the device, ie at least the front and rear films forming the document area, and the film increasing the static friction can be stacked correctly and appropriately on each other and in a single operation, eg. B. by welding or edge-side injection of adhesive can be peripherally bonded cohesively together. This efficient processing not only saves time during production, but also saves material and thus has optimization potential for the entire production process.

In a further development of the device according to the invention, the magnetic elements within the pocket between the rear plastic film of the document area and the static friction increasing foil secured against slipping by the rear side plastic film of the document area and the static friction-increasing film in a region surrounding the magnetic elements materially connected , in particular welded.

In a further embodiment of the device according to the invention, the head region has at least one preparation for the mechanical fastening of the device. Preferably, a perforation is provided, in which a fastening hook can engage. Such a perforation may be in the form of a slit or aufwei other masks adapted to the particular application situations forms.

By this embodiment, a particularly flexible design of the device according to the invention is provided, which can be releasably attached to objects in addition to attachment to ferromagnetic or ferrimagnetic or magnetic surfaces, for example by means of a hook or the like. Thus, such a device according to the invention can be used without further precautions to use flexible in a variety of application situations. In addition, with a corresponding arrangement of the perforation for the collection or storage of the device according to the invention also a filing, for example, in corresponding folders provided.

In a further embodiment of the device according to the invention for receiving documents, the head area has at least one second document area, wherein the second document area has at least two substantially flat plastic films, which are connected to each other at least partially cohesively, so that between the two plastic films further receiving area for documents is formed, wherein at least one of the plastic films is arranged transparent and at the front of the device.

With this further document area, a further, targeted identification, marking or design possibility of the device becomes available for example, to categorize, in addition to manufacturing documents that can be included in the first document area, such. B. a prioritization for the production. For example, the device can be provided with striking headers, legends, headings or identification codes, in particular color-coded differently, and herewith a systematic, uniform labeling or marking strategy can be implemented in companies or areas without having different devices for receiving documents, For example, made of different colored plastic films needed.

The provision of at least one second document area in the aforementioned type thus allows a particularly flexible use of the device according to the invention and at the same time a simplified and cost-saving production thereof, since the use of a variety of different materials can be avoided and thus a cost optimization can take place.

In one embodiment of the device according to the invention for receiving documents, the two, the receiving areas of the first and / or further document area forming plastic films are preferably not continuously bonded cohesively to each other at their lower, peripheral conclusion, but preferably have a broken connection line, such. B. a line of spot welds at predetermined intervals.

With the non-continuous cohesive connection in this embodiment, a very simple but effective possibility of aeration or even the outflow of liquids from the receiving area (s) for documents is made available in the production. In this way, the risk of unrecognizability of the recorded documents or even decomposition can be minimized, for example by penetrating liquid, as the receiving areas or areas are "dehydrated" by the interrupted connecting line of the two plastic films forming the document areas. This applies equally to oils or the like.

In a further embodiment of the device according to the invention for receiving documents, the first and second document areas are in one piece interconnected by the rear plastic film of both document areas is made in one piece.

The one-piece design of the backside film simplifies the production of the device according to the invention and the general stability benefits. Advantages include, for example, robustness and longevity of the device, which gives it clear advantages for use in harsh industrial environments, while at the same time providing flexibility through the provision of multiple document areas.

Preferably, in one embodiment of the document-receiving device according to the invention, the cohesive connection is selected from a group comprising welding, gluing, sealing, vulcanization, combination thereof and the like.

The first and / or the second receiving area for documents preferably has at least one first, upper, horizontal opening for inserting documents.

For the purposes of the present invention, an upper horizontal opening for loading documents is understood to mean a horizontal opening at the upper end of the respective receiving area when the device is horizontally suspended.

The advantage of this embodiment of the device according to the invention is the ability to make a simple, especially one-handed operation or one-handed operation of the receiving areas with documents, which is not only user-friendly but in difficult industrial environments also a prerequisite for occupational safety. For example, an employee can secure himself with one hand while, for example, he is loading the receiving area of the device with documents with the still free other hand.

Preferably, the stiction-enhancing plastic layer of the document receiving device of the invention is made of a flexible plastic material which preferably has a Shore D hardness of less than 50, more preferably less than 45, more preferably less than 40, and most preferably less than 35. Particularly preferably, the plastic friction or sliding friction increasing plastic film is preferably made of a soft elastic Plastic film with a Shore D hardness of less than 50, preferably less than 45, more preferably less than 40 and particularly preferably less than 30.

On the other hand, it is preferable that the backside plastic film of the document portion (s) has a higher Shore D hardness, rigidity, and / or material thickness than the stiction-increasing plastic film, so that the film existing in between the backside plastic film of the document area and the stiction-increasing film Although the magnetic elements accommodated on the pocket lead to a deformation or bulging of the soft-elastic film which increases the static friction, the backside plastic film of the document area remains essentially undeformed in the area of the magnetic elements and thus also no "pressing off" of the magnetic elements on the front side of the invention Device takes place.

By such a choice of material is thus ensured that the magnetic elements from the front of the device are not recognizable, since the device appears here essentially flat.

Preferably, the at least one magnetic element is a commercially available magnetic element such as an NdFeB magnet, SmCo magnet, Al-NiCo magnet, ferrite magnet, Somaloy magnet, plastic bonded magnet or the like, and preferably has a plate-shaped geometry in the form of a Button or a tablet or the like.

Further aspects of the invention will become apparent from the following description of an embodiment of the invention in conjunction with the drawings and the claims. It shows:

a schematic representation of the cross section of the device according to the invention for receiving documents in their attachment to a ferromagnetic or ferrimagnetic or magnetic adhesive surface.

FIG. 1 shows the front of an embodiment of the device according to the invention for receiving documents 1 with a first document area 2, which is formed from a rear side arranged plastic film 3 and a front side arranged thereon, transparent plastic film 4, which are welded laterally and at the bottom edge 5, respectively , The first document area has an upper, horizontal opening 8, by means of which the insertion of documents into the receiving area of the first document area can easily take place.

The device shown also has a second document area 10, which is formed from the rear side arranged plastic film and another arranged thereon front, transparent plastic film 4. The second document area is located in the head area of the device above the first document area 2. The rear side, both document areas forming plastic film 3 is made in one piece, as is also made FIG. 2 can be removed.

The second document area 10 likewise has an upper, horizontal opening 8, by means of which the insertion of documents into the receiving area of the second document area can easily take place. Preferably, categorization markings of the device 1 are made by the documents placed in the second document area, such as, for example, color stripes or head captions.

The transparent, front-side plastic film 4 of the second document area is also welded on both sides and at its lower edge 5, 12, the weld 12 is not continuous at the bottom of the second document area 10 but in the manner of a dashed line with predetermined distances of the welds or lines , As a result of this non-continuous welding, it is possible for the outflow, for example, of a fluid which flows through the horizontal opening 8 of the second document area into its receiving area for documents to flow off.

The head region of the device 1 shown here is designed trapezoidal, this shape is arbitrary and equally square, strip-shaped (rectangular), curved, rounded or similar. The same applies to the shape of the document areas 2, 10 and the geometric shape of the device 1 per se.

On the back of the rear plastic film 3, magnetic elements 6 are arranged in the head region of the device 1, by means of which the device 1 can be attached to ferromagnetic or ferrimagnetic or magnetic surfaces 7. In the present case, three magnetic elements 6 are provided, which are designed around in the manner of a magnetic button. Depending on the application, however, both the shape of the magnetic elements 6 and their number and geometric arrangement in the head region of the device 1 or else in the entire device can be chosen differently.

The head area also has preparations for the mechanical fastening 9 of the device in the form of perforations into which a special hook for suspending the device can be inserted. Thus, the device shown can also be attached to non-magnetic surfaces by means of a suitable hook.

FIG. 2 shows the back of the device for receiving documents 1 according to FIG. 1 , It can be seen that the rear plastic film 3 in the head region of the device 1 by another, the static friction and / or the sliding friction increasing plastic film 11, the magnetic elements 6 are covered. In the present case, the plastic film 11 which increases the static friction is applied in the entire head area and similar to how the transparent cover films 4 of the two document areas 2, 10 at least partially edge off the rear side film and / or the cover film. Likewise, a punctual or even full-surface bonding of the stiction-increasing plastic film 11 with the rear plastic film 3 is possible. In addition, the static friction increasing plastic film 11 but also completely cover the back portion of the device 1 and, for example, circumferentially welded to this edge or be provided only in the region of the magnetic elements 6, such. B. be glued to this.

If the device according to FIGS. 1 and 2 well, as in FIG. 3 attached by a lateral sectional view releasably attached to a ferromagnetic or ferrimagnetic or magnetic-adhesive surface 7, so comes the static friction-increasing plastic film between the magnetic elements 6 and the ferromagnetic or ferrimagnetischen or magnetic-adherent surface 7 to lie. Hereby, since the stiction-enhancing resin film is made thin, the magnetic attraction force between the magnetic member 6 and the surface 7 is hardly reduced, but at the same time, the friction coefficient between the device 1 and the surface 7 is increased to make it difficult to slip or displace the device becomes.

In particular, this effect also occurs in soiled or oil-wetted surfaces, which may improve the adhesion of the device to ferromagnetic or ferrimagnetic surfaces, particularly in industrial environments such as metal working production. The applicant has also examined this in a series of "haul-off experiments", which are reproduced below substantially qualitatively.

Furthermore, in FIG. 3 recognizable that due to the special choice of material and / or the material thickness of the stiction-increasing plastic film 11, which is preferably made soft elastic and thin, in comparison with the rear plastic film 3, which is preferably rigid and stronger, a deformation only the static friction increasing Plastic film 11 takes place and the rear plastic film 3, at least in the region of the magnetic elements substantially undeformed, ie remains flat.

For the investigations were devices for receiving documents as in FIGS. 1 to 3 described in a first experiment (A) mounted on a steel plate, and mounted in a second experiment (B) on an oil-wetted steel plate. Then the devices were pulled with a dynamometer in the direction of their underside parallel to the surface of the steel plate. The force at which movement of the device began was recorded from relevant measurement.

The plastic friction film used in this experiment (a) is a soft PVC film with a Shore D value of 33. Comparatively, corresponding devices 1 were used without a friction-increasing plastic film (b) and with hard plastic film (b). Measure PVC-encapsulated magnetic elements (c). The magnetic elements in all 3 experiments were NdFeB magnetic buttons of the same geometry and magnetization. A large number of measurements were carried out per experiment (n = 15) and their mean value was formed.

It can be seen that the measured devices (c) with hard PVC-encapsulated magnetic elements have the worst adhesion properties. This applies to both experiments (A) and (B).

In contrast, the measured devices (b), without a stiction-enhancing plastic layer between magnetic elements and surface, have a 2.80 and 2.26-well improved adhesion for experiments (A) and (B), respectively.

Finally, when measuring the devices (a) according to the invention, a further increase in adhesion of 1.95 or 1.49 times for the experiments (A) and (B) respectively.

It thus becomes clear that the stiction-enhancing plastic layer which is arranged on the device so as to lie between the magnetic element or elements and the ferromagnetic or ferrimagnetic or magnetic surface also significantly improves the adhesion of the device on soiled surfaces.
