Magnetic holder

The invention relates to a magnetic holder according to the preamble of

Claim 1.

A magnetic holder is used for the detachable fixation of magnetic

influenceable objects.

WO 96/13191 A1 discloses a magnetic holder of this type for mounting on walls or furniture surfaces for hanging objects of everyday use. In this case, at least one permanent magnet is inserted into a longitudinal channel of a bar that is open on the longitudinal side, whereby an object that is held in the vicinity of the bar is attracted by the magnet

and is held on the bar.

The permanent magnets inserted in the bar are invisible from the operator's side because they are covered on the front by a cover that can be inserted into the bar. The magnetic holding power

therefore penetrates the cover panel.

For detachment, the hanging object is pulled off with sufficient force to overcome the magnetic attraction between the magnet and the object. Such an object can be, for example, a tea towel, a hand towel, a pot holder or the like, in its edge area or elsewhere a piece of metal, depending on its shape, size or preference

is sewn in.

The disadvantage of this magnet holder is that the individual magnets are not protected from environmental influences. The magnets corrode when they are exposed to the moist air in the area of a hob. In addition, a layer of dirt and grease and dust collects on the bar after a while

that is difficult to solve. Another disadvantage is that a movable and pluggable cover panel must be used to cover the end faces of the permanent magnets, which must not be less than a certain thickness. Due to the finite thickness of the cover panel, the magnetic holding force of the magnets is reduced.

The above arrangement is also only suitable for hanging objects. A

There is no provision for holding objects lying down.

The present invention is therefore based on the object of developing a magnet holder in such a way that an easy-to-clean and protected fastening option with high holding force on a horizontal

Countertop can be provided.

The object on which the invention is based is achieved by the features of the independent patent claim, while advantageous embodiments and developments of the invention can be found in the subclaims.

According to the invention, at least one permanent magnet is attached to an underside of a worktop and acts with respect to its magnetically effective holding surface through the worktop and that the permanent magnet is fixed by a potting compound and shielded from environmental influences

is.

Such a potting compound consists of a plastic, preferably one

Synthetic resin such as epoxy acrylate, epoxy resin or polyester resin.

For example, on the underside of a worktop there are recesses in which the individual permanent magnets are arranged, so that there is a sufficiently strong magnetic field in the area of the worktop surface to be able to influence the magnetic field applied to the surface

To hold and fix the object magnetically.

The surface is either the front side or the top side of the worktop, with a hob in the top side in addition to:

Permanent magnets can be embedded.

In the following, the term “magnet” is generally used for the

Permanent magnets used.

The magnets are invisible to a person and conveniently built into the worktop, making the magnets less susceptible to dirt and

are protected against environmental influences.

The worktop is preferably designed as a stone, natural stone, ceramic or composite plate, but can also be made of wood, plastic, glass, composite material, wood composite material, wood laminate, from one

Wood fiber material or made of polymethyl methacrylate.

The magnets are preferably permanent magnets, e.g. made of a neodymium-iron-boron alloy (hereinafter “neodymium” magnet) with a quality of N45, with an adhesive force of approx. 5.3kg, a diameter of 12 mm and a height of 10 mm. Such magnets have strong magnetic fields with small dimensions and are therefore particularly suitable for use in a kitchen worktop, since the drilling diameter is limited due to the manufacturing process and only small magnets can be installed. Preferably two or more magnets are provided.

The binding force is determined using the properties of the worktop material, the size of the contact area and the distance to the surface.

When positioning a magnetically influenceable object in the effective area of the magnetic field, the force of attraction depends on the distance between the magnet and the object. The greater the distance between the magnet and the object, the lower the force of attraction.

The thickness of the worktop between the top of the worktop and the top of the magnet arranged in the recess can be between 1 mm

and 50 mm, preferably between 2 mm and 5 mm.

Tests by the inventor have shown that such small dimensions can be implemented particularly advantageously by using an underfloor unit, since the drilled recesses can be positioned close to the surface with such a unit. This makes it possible to make a recess in the worktop at a distance of just 1 mm from the surface. A possible weakening of the material through the hole in the edge area is counteracted by the introduction of the potting compound. The advantage of using an underfloor unit is that the worktop does not have to be turned over in order to make the cutouts. A worktop can, for example, have a dimension of 2 by 3 meters and is accordingly heavy and requires great effort

turn.

However, it is also possible to rotate the worktop and to make the holes or millings from above, for which no special underfloor unit is necessary. A conventional blind hole drill or milling cutter can be used for this purpose.

The holes, which are made very close to the front side, can be easily implemented with a blind drill or an underfloor unit, since the forces act almost exclusively vertically during machining

Distances of only 1mm are possible.

One or more iron metal plates that are connected to a substance are preferably used as the magnetically influenceable object. Such a substance is, for example, a tea towel, a hand towel, a pot holder or the like, in its edge area or elsewhere

Metal piece is sewn or sewn into the depending on shape, size or preference

Edge is pushed in. The ferrous metal pieces or magnets can be arranged on several areas of the fabric.

As an alternative to the ferrous metal plates, flat permanent magnets can also be used

that are connected to the fabric.

In a further embodiment, the permanent magnets can consist of foam rubber or synthetic foam with homogeneously embedded magnetic iron powder. Such magnets have the advantage that they are relatively light and are designed to be soft and flexible, so that they hardly stand out at all after being sewn in.

The ferrous metal pieces and the one-piece permanent magnets can also be surrounded by a plastic jacket in order to shield them from moisture.

Kitchen towels, hand towels and pot holders etc. are immediately available due to the side attachment to the worktop and can dry after use.

In a further embodiment of the invention, at least two magnets introduced into the recesses hold a plate-shaped barrier placed on the top of the worktop, which can be magnetically influenced

Feet stands up on the top and clings.

In another embodiment, the feet and the barrier are dispensed with

itself can be influenced magnetically.

Such a barrier can be, for example, a plastic or stainless steel grille, which can be bought ready-made and can be expanded with appropriate magnets to match the ones built into the worktop

A marking can be provided on the top of the worktop indicating the position of the magnets integrated in the worktop, e.g. in shape

two adjacent circles.

In a further embodiment, a further holder is magnetically attached to the plate face by means of this magnetic holder of the worktop. The advantage of this detachable holder relates to maintenance, and when cleaning the worktop, the holder can be removed briefly in order to clean the support surface of the holder.

So it can also be provided for optical reasons that the special

Bracket is only attached to the plate for a short period of time.

Such a detachable holder can be, for example, a railing bar or a hook in the wash basin area for damp and wet or dripping cleaning cloths, which can be e.g. be mounted at the front on the sink edge and through the inventive magnet holder in the stone of the worktop

cling.

Thus, a magnetic cleaning rag holder, which consists for example of a bracket and a magnet attached to it, can be easily inserted into a sink and is held by a magnet built into the worktop in the area of the sink. The holder can be moved and easily removed again.

The present invention is thus at least one magnet that is fixedly connected to the worktop and is not visible to a person and is arranged in such a way that an object can be attached magnetically. This is preferably a permanent magnet that is in the

Use to build up an attraction to the magnetizable elements.

Figure 1 shows a top view of a worktop, which is preferably designed as a natural stone, ceramic or composite plate. According to the invention, the magnets incorporated in the worktop 1 cannot be seen in plan view, so that an observer can only see the planar upper side 2 of the worktop 1. FIG. 2a shows the underside 3 of the worktop 1, with the worktop 1

different recesses 5a, b, c are incorporated.

Recess 5a is designed as a simple round bore, recess 5b as a double bore and recess 5c is also designed as a double bore, with 5b and 5c differing in their orientation by 90 °.

A round magnet 6a is inserted into the recess 5a.

The recess variants 5b and 5c, which are designed as double holes, i.e. two laterally overlapping round bores are formed, are required by one that is larger than the simple drilling diameter

To accommodate magnets 6b, 6c.

In a later process step, the individual bores, including the magnets located therein, are filled with a potting compound 25. Polyester resin, for example, is used as the potting compound 25. This has the advantage that the magnet is protected against moisture, since a kitchen worktop in particular comes into contact with different liquids and steam. In addition, the previously weakened by the hole

Worktop reinforced by pouring the potting compound.

The magnetic material used, which is, for example, neodymium, corrodes in

enclosed in the borehole to shield it from environmental influences.

FIG. 2b schematically shows the front view of the worktop 1 with the magnets 6a, b, c fitted into the drill holes 5a, b, c. The magnets are enclosed in the drilled holes 5a, b, c via the potting compound 25.

According to the illustration according to FIG. 2b, it can be seen that the magnets 5b, 5c are cylindrical and are aligned with their round end face in the direction of the end face 4 of the worktop 1.

A plurality of magnets are preferably installed in a worktop 1, with which a user can intuitively find the individual magnets when guiding an object to be hung along. Such an object is, for example, a tea towel into which a metal plate is sewn, which adheres to the end face 4 of the worktop 1 due to the magnets 6.

The magnet 6a is also cylindrical, but due to the positioning, its round end face points in the direction of the upper side 2.

Due to the different positioning of the magnets, the magnetic field can be specifically aligned depending on the intended use.

FIG. 3 shows the worktop 1 in which, by way of example, a magnet 6c, 6a is arranged in each case on the opposite edge regions of the end faces 4a, b. In the edge area of the left end face 4a, a lying magnet 6c is arranged, the south pole (S) of which points in the direction of the end face 4a. This positioning of the magnet 6c can also be seen in FIGS. 2a / 2b. The magnetic field, which is represented by the magnetic field lines 7, acts beyond the end face 4a and the end face thus forms the holding surface 15a. As a result of this arrangement of the magnet, the magnetic force is strongest on the end face 4a, so that a counterpart 8 entering the magnetic field is attracted. The advantage of this embodiment is that the counterpart 8 can be guided directly onto the magnet 6c at specific points, since the magnetic force is greatest here.

The magnet 6a is fitted into the worktop 1 in the area of the opposite end face 4b. This positioning of the magnet 6a can also be seen in FIGS. 2a / 2b. Due to the upright arrangement of the magnet 6a, the south pole (S) point in the direction of the upper side 2 and the north pole (N) in the direction of the lower side 3. The force on a counterpart is great only in the area of the individual magnetic poles S and N. The boundary between the poles is shown by the dashed line 22. The magnetic field itself is represented by the magnetic field lines 7.

A counterpart 8 approaching the magnetic field and the magnet laterally is attracted more strongly to the north pole or more strongly to the south pole of the magnet 6a, depending on the positioning above or below the dashed line 22. Thus, the counterpart in the upper area of the end face 4b near the top 2, or in the lower area of the end face 4b, near the bottom 3,

to be ordered. The front side forms the holding surface 15b.

When using a magnetic counterpart 8, depending on the polarity of the counterpart, adhesion to the upper or lower area of the end face 4b can take place. A counterpart with a magnetic north pole is repelled by the magnetic north pole of the magnet 6b and is attracted by the south pole above the dashed line 22 and thus adhered to the end face 4b, near the top 2.

It can thus also be determined whether the counterpart 8 can be fixed, for example, in the upper area of the worktop 1 or in the lower area of the worktop 1. This has aesthetic advantages for a tea towel attached to it later.

FIG. 4 shows the recess 5 being made in the worktop 1. For this purpose, an underfloor unit 14 is used for milling and drilling, for example, in order to process the worktop from the underside without the worktop having to be turned. The underfloor unit 14 takes over

a drill chuck at the end of an arm 24 a drill 13 (e.g. long hole or

Dowel drill). The drilling unit is then brought closer to the underside 3 in the direction of arrow 16, the arm 24 engaging under the worktop 1 and the drill 13 making the drill hole 5 in the underside 3 of the worktop 1. FIG. 5 shows a tea towel 17 in which two, by way of example, two differently shaped counterparts 8a, 8b are introduced. The counterparts 8a, 8b are arranged in the corner areas of the tea towel. However, the present invention is not restricted to the use of a tea towel; pot holders, knives, kitchen aprons or other utensils which contain a magnet or a metal or steel counterpart can also be used with which a connection to the

Magnet 6 can be received.

FIG. 6 shows a detailed view of a tea towel 17 with a sewn-in permanent magnet 26 which is surrounded by a plastic jacket 9. The advantage of this plastic jacket 9 is that the permanent magnet 26, which is susceptible to moisture, is shielded and therefore does not come into contact with moisture and is protected from corrosion. The plastic jacket 9 is surrounded on both sides by the fabric 10 which is sewn around the plastic jacket by the seam 11.

FIG. 7 shows a further embodiment of the invention, a hob 19 being embedded approximately in the center of the top 2 of the worktop 1. This hob 19 can be shielded from a person by a flat and upright barrier 20, whereby, for example, child protection is provided so that a child does not get into the danger area of the hob. This barrier 20 has magnetically influenceable feet 21, which cooperate with the magnets hidden in the worktop 1 when the barrier is placed on the top 2 and the feet 21 adhere to the worktop 1 due to the magnetic force.

This barrier 20 can also be used as a splash guard in order to prevent, for example, hot fat from splashing on a person while cooking.

This barrier 20 serves as a splash guard, as a result of which the surroundings are shielded from the hob. FIG. 9 shows the front view of FIG. 7, the magnets 6 being shown which are fitted in the recesses 5. The worktop 1 stands with the legs 23 on the ground. The magnets 6 are held in the recesses 5 by the casting compound 25.

This arrangement of the magnets 6 makes it possible to fasten the barrier 20 on the worktop 1. The barrier 20 is placed with your feet 21 on the top 2 of the worktop 1 and held by the magnetic force. The feet 21 are stamp-shaped in the example shown in FIG
