Abstract

Attachment system for the magnetic attachment and alignment of objects on walls using strong permanent magnets (exploded view 1), characterized in that a strong permanent magnet in the form of a flattened cylinder with a height of 5-10 mm and a diameter of 16-32 mm ( 2) with a centered bore to the longitudinal axis of both poles and trough-like depression on one side of the bore for receiving a commercial countersunk screw (1) is fitted, which can be fixed by means of suitable for the respective wall countersunk screws (1) and dowels (4), without the countersunk screw protruding beyond the edge of the magnet.

Description

Suitable objects / materials:

• 1. pictures
• 2. Pinboards
• 3rd mirror
• 4. small shelves
• 5th other, acc. the respective maximum load capacity of the Systems

conventional Wall fixtures made of objects such as those mentioned above by means of a nail or a screw / a screw hook with dowels, to which the objects to be fastened then at suitable receiving points like eyelets, holes Tensioning cables or simply attached to the frame edge.

• 1. an manchen Wänden aufgrund der ungleichmäßigen Beschaffenheit an vielen Stellen kein sicherer Halt gewährleistet ist, z. B. in Altbauten oder bei gefliesten Wänden, wenn Fliesen nicht angebohrt werden sollen, und dadurch die Befestigungselemente nicht an den gewünschten Stellen angebracht werden können.
• 2. insbesondere bei der Anbringung von mehreren Objekten nebeneinander eine gleichmäßige Ausrichtung nur bei sehr präzisem Arbeiten möglich ist und einmal aufgetretene Fehler, z. B. ein Abrutschen beim Bohren des Dübellochs oder ein versehentliches Bohren an der falschen Stelle, nur schwer oder gar nicht korrigiert werden können.

The disadvantage of these designs is that for vertical and horizontal alignment of the objects, the fasteners must be placed at exactly predetermined locations of the wall, so that the vertical alignment is ensured. Problems arise in particular by the fact that

• 1. On some walls due to the uneven nature in many places no secure grip is ensured, for. As in old buildings or tiled walls when tiles are not to be drilled, and thus the fasteners can not be attached to the desired locations.
• 2. in particular with the attachment of several objects side by side uniform alignment is possible only with very precise work and once occurred errors, eg. B. slipping when drilling the dowel hole or accidental drilling in the wrong place, difficult or impossible to be corrected.

alternatives To this type of attachment represents the hanging of the objects by wire ropes o. Ä. Of a bar or other attachment point, which z. B. is sometimes common in galleries, but visually disadvantageous, visible fasteners outside the obscured by the object wall surface makes necessary.

Of the in the protection claims specified invention is based on the problem, a flexible fastening system to create that is suitable, the o. g. Objects in the desired Orientation to be fixed to a wall, without the fasteners, which are connected to the wall, at previously exactly defined Points must be attached, the objects later be aligned, moved or even exchanged for others can, without the wall-mounted parts must be moved and without that elements of the fastening system outside of the object hidden wall surface visible are.

With the invention is achieved by using one or more of mentioned in the protection claims Fastening systems o. G. Objects under the specified specifications on walls can be attached.

First, be one or more metal plates gem. Protection claim to 2 on the back of the object with screws or double-sided self-adhesive pads or applied to a suitable adhesive. The attachment takes place preferably centered on the object either in the upper third (1 plate) or horizontally in a line in the upper third of the object (2 Plates) or perpendicular to each other evenly spaced from the edges of the object (2 plates). The magnets gem. Protection claim to 1 will then using screws and dowels attached to the wall.

in this connection just make sure that the position of the magnets to each other in about the position of the metal plates to each other on the Object corresponds and the position of the magnets on the wall in about the desired Position of the object on the wall corresponds. The object then becomes put the metal plates on the magnets so that they are located within the plastic circles and sticks securely to the Wall.

The Number and size of used Magnets and metal plates depend on the weight of the object. commercial Picture frames and other objects weighing less than 5 kg are used by 2 the magnets used permanently without slipping and without support held. The plastic circles serve only as an orientation and alignment aid.

The Object hangs now sure, can be removed at any time without damage and also be centered or hung vertically by simply moving. The magnets must not be attached to previously defined locations. The possibility the displacement of the object is only by the inner diameter the plastic circles limited.

To prevent jamming, always use at least two magnets and metal plates regardless of the weight of objects whose rear surface is large enough. For heavier objects or low load capacity of a magnet, due to low load capacity of the dowel correspondingly more magnets are to be used, of which several on a metal can adhere to the plate.

Should the suspended one Object on the back have a cavity in which the metal plates according to the protection claim to be attached to 2. come spacer according to protection claim to 3. to the magnet used to the distance of the metal plates to balance with the magnets.

at execution the metal plate gem. Protection claim to 4. in a size between 774 mm × 474 mm and 774 mm × 114 mm, the system itself can be used as a pinboard for attaching notes and Images can also be used with the help of other permanent magnets Design of the visible side can be arbitrary, z. B. by a thin plate glass, respectively.

Further Advantages are the following:

1. Change of the object

If a new object with a size different from the fixed object at the Wall should be attached, as far as the size is not too strongly deviates, only metal plates gem. the protection claim to 3. be attached to the new object at a suitable location. Because the Metal plates are relatively freely positionable on most objects, can the magnets, originally for an object other size provided were, continue to be used. For example, it would be possible for galleries, always To attach new pictures to once attached magnets, too if they have different sizes. Walls can too with a regular grid be provided by magnets, which are always new combinations of objects hold.

2. walls with very little / different stops

is the wall to which the object is to be attached, only in places for attaching dowels suitable and can not be positioned so that either two magnets in the desired one Height horizontally next to each other or perpendicular to each other at the point where the object should be fixed, can safely hold the Magnets also on any "load-bearing" points of the wall be attached. In this case, the magnets are first pegged, and only then according to their position on the wall the position the metal plates fixed to the object. For example, in a rectangular Picture, would be it quite possible that one metal plate in the upper right, the second however located in the lower left part. It would still be a safe vertical Attachment possible.

can a magnet due to its debauchery carry less weight than he due to its magnetic appeal could hold so can 2 or 3 magnets are pegged side by side as a group, so the weight on several dowels to distribute.
