Description

The present invention relates to a writing board with a writing plate having a continuous writing surface.

Writing boards of the type mentioned at the outset have proven themselves in practice for visualizing ideas and for supporting communication between members of a team. Such writing boards usually have a continuous or planar writing surface, that is to say a writing surface designed without interruptions, which can be written on and then wiped off with pens or markers. E.g. the writing surface can be a substantially rectangular surface his. Typically, such writing boards are relatively heavy and bulky. However, the use of modern creative methods and approaches such as design thinking, agile work or serum requires not only to be able to quickly record information, but also to be able to rearrange it continuously and flexibly. For example, to be able to quickly present the results of a brainstorming session in another office.

Based on this, the object of the invention is to provide a writing tablet which can be used flexibly and is portable. At the same time, high stability is required.

This object is achieved according to the invention in a writing tablet of the type mentioned at the outset in that the writing tablet has a stiffening plate and a carrier plate arranged between the writing plate and the stiffening plate, the carrier plate being made, in particular, from an expanded polypropylene.

Such a writing tablet according to the invention is light in weight and nevertheless stable. The carrier plate forms the "core" of the writing board, while the writing plate and the stiffening plate are spaced apart from one another by the carrier plate and form the "cover layers". Such a sandwich-like structure is characterized by high bending stiffness and low weight. this will Favored in particular in that the carrier plate is made of an expanded polypropylene, which is heavy-duty and yet light. The sandwich-like structure of the writing board gives it a special degree of stability that goes far beyond the stability of the individual components. The writing plate and the stiffening plate are each subjected to tensile stress when the writing tablet is subjected to bending stresses and, taken on their own, can be designed to be very tensile but not very rigid. The carrier plate, which can preferably be at least 5 times, in particular 10 times, as thick as the writing plate or the stiffening plate, spaced the two plates apart from one another, so that one or the other is loaded under tension in the event of a bending load. As a result, the writing board can be designed to be very light, yet rigid and dimensionally stable.

Due to the relatively low weight, a writing tablet according to the invention can be transported by only one person without great effort. This is particularly advantageous if the writing board should be regularly and flexibly rearranged in different positions, as is required, for example, when working in multidisciplinary, self-organizing teams. Due to the high flexural rigidity, the tablet is particularly robust, which - even with regular transport - enables a long service life of the tablet.

Expanded polypropylene may refer to a material made by inserting polypropylene beads into a mold and heating them with steam. By heating and applying pressure, the individual polypropylene beads can combine to form a solid material. Expanded polypropylene is light and yet highly resilient. In addition, expanded polypropylene can be easily removed from the mold, since it can be plastically deformed temporarily. This enables the carrier plate to be produced easily.

It is preferred if the writing surface is designed as an enamelled sheet. As a result, a robust, in particular scratch-resistant, writing surface is achieved which can be wiped off permanently. This is advantageous for a high rewritability of the writing surface. It is particularly preferred if the writing plate is made of a ferromagnetic steel sheet. This makes it possible, for example, to detachably attach notes or signs to the writing surface by means of magnets.

In the context of an alternative preferred embodiment, the writing plate can be formed using a plastic plate, in particular consist of a plastic plate. It is particularly preferred if the plastic plate comprises melamine resin (melamine-formaldehyde condensation resin), in particular consists of melamine resin. Melamine resin is characterized, among other things, by high weather resistance and scratch resistance with a relatively low weight. This contributes to one long life of the tablet. Transport of the writing board is also facilitated.

The stiffening plate can also be formed using a plastic plate, in particular consist of a plastic plate. It is particularly preferred if the plastic plate comprises melamine resin (melamine-formaldehyde condensation resin), in particular consists of melamine resin. In particular, the stiffening plate can be perforated over its surface. This enables a particularly low weight to be achieved with sufficient stability.

Preferably, the writing board has an edge which is formed by the carrier plate and is preferably formed all around the entire circumference, the edge formed by the carrier plate over an edge of the writing plate and / or an edge of the stiffening plate, preferably between 1 and 10 cm , more preferably protrudes between 3 and 6 cm, in particular along the entire circumference. The edge formed by the carrier plate can also protrude over the edge of the writing surface 7-11 cm, in particular 8-10 cm, in particular 9 cm, and / or over the edge of the stiffening plate 2-6 cm, in particular 3-5 cm, in particular 4.5 cm. The edge preferably serves as a grip edge and enables the writing tablet to be transported in a simple manner without having to touch the writing surface. This can prevent information recorded on the writing surface from being transported Writing board to be blurred. Because the edge formed by the carrier plate is made of an expanded polypropylene, a particularly grippy and non-slip surface is achieved. Expanded polypropylene is also characterized by high elasticity and energy absorption. This enables the edge to be protected against impact ("crumple zone"). In this way, transport damage to the writing tablet, for example if the writing tablet falls onto a floor, but also damage to walls, pieces of furniture or people can be prevented.

The carrier plate preferably has at least one recess on its edge, preferably two recesses arranged on two opposite edge sections, in particular four recesses distributed over the circumference of the carrier plate. The recesses preferably serve as recessed grips, which enables the writing tablet to be transported particularly easily. The recesses can also be designed as an engagement point for fastening means, for example for fastening the writing board to a wall (see below). It is particularly preferred if the at least one recess is arranged on the side of the edge facing away from the writing plate. This makes it possible to place the writing board on a floor in a particularly ergonomic manner or, for example, to fasten it to a holder. It is further preferred if the at least one recess is arranged approximately centrally with respect to the side lengths of the carrier plate.

This enables hanging attachment "in balance".

It is preferred if the stiffening plate is designed as a perforated plate. This ensures high stability with low weight. Such a perforated plate has sufficient tensile strength with a greatly reduced basis weight.

The stiffening plate preferably has a layer of a loop-forming material of a hook-loop connection system, in particular velor or a velor-like material, on the side facing away from the carrier plate. This makes it possible to form a hook-loop connection (for example a Velcro fastener) between the writing plate and an external component which has a layer of a hook-forming material of a hook-loop connection system. The writing board can thus be easily and quickly attached to different components (e.g. fasteners, risers, frames, etc .; see below), for example using a Velcro fastener connection, and then released again. It is also possible for the layer on the stiffening plate to be formed from a hook-forming material of a hook-loop connection system. It is further preferred if the layer is glued to the stiffening plate. This creates a reliable connection between the stiffening plate and the layer of loop-forming material ensured (no delamination of the layer).

It is preferred if the writing plate, the carrier plate and the stiffening plate are integrally connected to one another, preferably by means of an adhesive connection. A reliable connection of the plates is achieved by the, in particular flat, integral connection, which contributes to a high stability of the writing board. This also has the advantage that no additional frame is required to connect the individual plates.

The edge of the writing board can consequently be formed in a structurally simple manner by the carrier plate (see above). The carrier plate can thus form the edge of the writing board over the entire circumference. For example, it forms a shock protection.

Part of the present invention is also a system comprising a writing board according to one of the preceding claims and at least one fastening element for releasably fastening the writing board to a wall, wherein the fastening element has at least one flat connecting section made of a hook-forming material of a hook-loop connection system for connection to of the layer of a loop-forming material of a hook-loop connection system of the writing board and a fastening section for releasably fastening the fastening element to the wall, the fastening section preferably as a suction cup and / or is designed as a magnet and / or comprises a screw connection.

This enables the writing board to be attached to different surfaces in a simple and flexible manner. It is particularly preferred if a, preferably elastic, intermediate element is arranged between the connecting section and the fastening section, which serves as a carrier for the connecting section. For a reliable fastening of the writing board, it is particularly preferred if a plurality of fastening elements are provided which are distributed over the velor layer.

The intermediate element is preferably cambered or curved and has a receiving surface for the connecting section which is curved outwards (in the direction of a writing plate to be fastened). The curvature enables a particularly simple detachment of the connecting section from the layer of the writing board.

Designing the fastening section as a suction cup enables the writing board to be fastened particularly easily to smooth surfaces, such as, for example, glass walls. An embodiment of the fastening section as a magnet enables fastening to magnetizable surfaces, such as steel sheets. The screw connection enables the fastening element to be securely fastened to walls of various types (for example wood, stone, concrete or drywall).

Part of the present invention is also a system comprising at least one writing board according to one of the preceding claims and a sliding wall, the sliding wall comprising a frame structure and a fastening area for releasably fastening the at least one writing board. The sliding wall can perform the function of a partition and at the same time serve as a holder for the at least one writing board. Such a system makes it possible to subdivide office or project rooms, in particular open-plan offices, flexibly and as required and / or to combine several writing boards into information clusters. It is particularly preferred if the frame structure is made of aluminum, as a result of which a particularly light construction of the sliding wall and thus simple displacement of the sliding wall is achieved.

It is further preferred if the system comprises a ceiling rail for fastening to a room ceiling and / or comprises a floor rail for fastening to a room floor and the sliding wall is displaceably arranged in the ceiling rail by means of a guide element arranged on the frame structure and / or by means of at least one the frame structure arranged roller is slidably guided in the bottom rail. This enables a particularly reliable and quiet displacement of the sliding wall. The weight of the sliding wall preferably bears on the at least one roller. It is particularly preferred if the ceiling rail is designed as a U-profile. This prevents the sliding wall from tipping over.

It is further preferred if the fastening area comprises at least one flat attachment element which is arranged in a surface delimited by the frame structure and divides this surface into a first partial surface and a second partial surface. The flat attachment element is preferably the same size or slightly larger than a writing board. It is particularly preferred if the attachment element is arranged approximately in the center in the height direction of the frame structure, so that the writing board is arranged at the viewing / writing height of a person. This enables comfortable writing and / or reading of information on the writing surface of the writing plate.

By surface or partial surfaces are meant flat areas in the plane spanned by the frame structure. In other words, the surface or partial surface extends orthogonally to the viewing direction of the writing surface of the writing board when it is accommodated in the frame structure. The first and / or the second partial surface are preferably “open”, that is to say not filled out by a surface element, so that one can see through the partial surfaces. This contributes to simple communication between people on different sides of the sliding wall.

The attachment element is preferably made from sheet metal, in particular from a ferromagnetic steel sheet. The attachment element preferably has one Fastening device for fastening the at least one writing board. It is possible for the fastening device to comprise at least one holding element which engages in a recess in the edge of the writing tablet. The at least one holding element is preferably designed as a negative form of a recess in the carrier plate. This enables a particularly secure mounting of the writing tablet. It is also possible for the at least one writing board to be attached by means of magnets. It is preferably possible to attach two writing boards (one on the front and one on the back of the flat attachment element).

In the context of an alternative preferred embodiment, at least one surface element can be arranged in the first and / or in the second partial surface, which completely or at least partially fills the respective partial surface and is preferably made of glass and / or wood and / or made of felt and / or perforated sheet is made. Depending on the selected material of the at least one surface element, the sliding wall can be flexibly adapted to different environmental conditions (size of the room, lighting conditions, construction of the workplaces).

A flat element made of glass is characterized, for example, by high light permeability and additional noise insulation, while a flat element made of wood provides effective privacy protection. Surface elements made of felt and / or perforated steel sheet form sound absorption surfaces and enable a high level of noise insulation. In the case of surface elements made of felt, it is particularly preferred for high noise insulation if two surface elements separated by an air gap are arranged in the first and / or in the second partial surface. The perforated sheet can be, for example, a microperforated steel sheet from the company akustik & innovation GmbH, CH-4612 Wangen near Olten, Switzerland. Other materials are also conceivable.

Part of the present invention is also a system comprising a writing tablet according to one of the preceding claims and a frame for placing the writing tablet on a floor, the frame being designed as a multi-leg, in particular as a tripod, and having a support section for supporting the writing tablet, and wherein at least one flat fastening section of a hook-forming material of a hook-loop connection system for connection to the layer of a loop-forming material of a hook-loop connection system of the writing board is preferably arranged on at least one of the legs.

This makes it possible to flexibly set up the writing board at different positions, for example within a room, without having to provide additional fastening means, for example on the ceiling, the floor or the walls of the room. The frame is preferably designed in the manner of an "easel" with legs that run obliquely to a room floor. Preferably the To set up, the writing tablet is first placed on the support section and then leaned against preferably two of the oblique legs of the frame. The formation of a hook-loop connection between the writing board and the at least one fastening section of the frame can prevent the writing board from tipping over; this also prevents the tablet from slipping when writing. The distance of the support section from the floor is preferably chosen such that the writing surface of the writing board is arranged at a standing / writing height of a person of average height, for example 175 cm or 165 cm. This favors comfortable writing and / or reading of information on the writing surface. Furthermore, it is possible for the frame to have a storage section for storing objects (for example markers, magnets, sponges, etc.). However, the distance of the support section from the floor can also be adjustable. For example, the support section can be arranged displaceably on the frame. It can preferably be moved at least in a range of 80-90cm, in particular 70-100cm, in particular 70-110cm, above floor level.

Part of the present invention is also a system comprising at least one tablet according to one of the preceding claims and a wall bracket for releasably attaching the at least one tablet to a wall, the wall bracket at least one holding body for holding a tablet and a fastening device for releasably attaching the comprises at least one holding body on the wall. This enables simple and secure attachment of the at least one writing tablet to a wall.

The at least one holding body preferably has a holding section for engaging in a recess in the carrier plate. The writing board therefore only has to be “hooked” into the holding section for fastening, without additional fastening means being required. This favors easy hanging and hanging of the writing board, which is particularly advantageous for flexible working. Depending on the selected recess, the writing board can be hung in portrait or landscape format. The shape of the holding section is preferably designed as a negative shape of a recess. This enables a particularly secure mounting of the writing tablet.

It is further preferred if the fastening device comprises an intermediate body, preferably in the form of a rail, and at least one fastening body for releasably fastening the intermediate body to the wall, the holding body at least partially encompassing the intermediate body. Designing the intermediate body as a rail makes it possible to fasten a plurality of holding bodies to the intermediate body and thus to fasten a plurality of writing boards to a wall using only one wall bracket. It is particularly preferred if the at least one holding body is arranged displaceably along the intermediate body. This is for a flexible arrangement of the Chalkboards beneficial. Furthermore, a flexible use of the wall bracket is made possible by designing the intermediate body as a rail; For example, additional objects, such as clothes hooks or holders for flipcharts, can be easily fixed to the wall bracket. The at least one fastening body can preferably be fastened to the wall by means of fastening means, in particular by means of a screw connection.

It is further preferred if at least one sliding element is arranged between the holding body and the intermediate body. This enables friction and wear-minimized sliding of the at least one holding body along the intermediate body. The at least one sliding element is preferably designed as a felt element.

Part of the present invention is also a system comprising a above-described writing tablet and a carrying strap for carrying the writing tablet, the carrying strap at each of its two ends comprising at least one flat fastening section made of a hook-forming material of a hook-loop connection system for connection to the layer a loop-forming material of a hook-loop connection system of the writing board. For transportation, the carrying strap only has to be pressed with its flat fastening sections against the layer made of a loop-forming material of the writing plate, whereby a holding effect is achieved. This enables the writing board to be opened easy way to transport. It is particularly preferred if the shoulder strap is designed as a shoulder strap. This enables particularly convenient transportation of the writing tablet, since a person has both hands free when transporting the writing tablet, for example to open doors and / or to transport other objects such as pens, sponges or memos to a new location.
