Description

Field of the invention

The invention relates to a furniture glider and a method for its production. In particular, the invention relates to a furniture glider for the bottom-side arrangement of a piece of furniture, in particular chair. Furthermore, the invention relates to a piece of furniture, in particular chair, with inventive furniture glides arranged thereon.

Background of the invention

Tables, chairs and other furniture are frequently moved and can cause damage or scratches on the floors, especially wood or parquet floors. In addition, when moving chairs unnecessary noise that can be avoided by the use of suitable furniture glides. These so-called furniture glides are mounted, for example, under chair and table legs. It is known to produce such furniture glides made of felt.

With felt glides, chairs, tables or other furniture can be moved across the floor largely silently. However, felt gliders have the disadvantage that they easily absorb dust, moisture and dirt due to their surface structure and material properties. Absorbed dirt, especially hard particles, such as grains of sand, can cause a move of the furniture leaves scratches in the floor. Another disadvantage of the felt pads is that they have a low abrasion resistance and thus a low life, which leads to the fact that the gliders must be changed frequently, especially in furniture that moves frequently, such as chairs.

Object of the invention

The object of the invention is therefore to provide a furniture glider, which at least partially avoids the disadvantages known from the prior art and is characterized by a lower dust or moisture absorption and improved abrasion resistance.

Inventive solution

According to the invention, this object is achieved by a furniture glider, a method for producing a furniture glider, and a piece of furniture with a furniture glider according to the independent claims. Advantageous embodiments of the invention are specified in the respective dependent claims.

Accordingly, a furniture glider is made available from a textile fabric for preferably bottom-side arrangement on a piece of furniture, in particular a chair, wherein the furniture glider has a sliding surface and a mounting surface opposite the sliding surface, and wherein the textile fabric is treated with a polymer at least on the sliding surface side.

By at least sliding surface treatment with a polymer a largely smooth surface structure of the sliding surface of the furniture glides is achieved, resulting in a greatly reduced dust and / or moisture absorption. In addition, the abrasion resistance of the furniture glide is in any case increased sliding surface side.

The textile fabric may have felt, in particular wool felt, and the polymer preferably comprises polytetrafluoroethylene (PTFE). Colloquially polytetrafluoroethylene is often referred to by the trade name Teflon DuPont.

Due to the very low coefficient of friction of PTFE, the gliding felt or sliding felt treated with PTFE slides much better than conventional felt glides. The extremely low surface tension of PTFE means that the dust and / or moisture absorption is further reduced.

It is advantageous if the textile fabric is impregnated on the sliding surface side with the polymer or with the PTFE. As a result, not only is the surface of the textile fabric treated with the polymer, but an entire outer layer, in particular a sliding surface-side outer layer of the textile fabric is treated with the polymer or with the PTFE, so that even when attrition, the original properties of the invention Furniture glider largely remain. The life of the furniture glides can be increased even further.

• – das textile Flächengebilde eine Stärke zwischen 2 mm und 10 mm, vorzugsweise zwischen 3 mm und 7 mm, ganz besonders bevorzugt 5 mm aufweist, und/oder
• – das textile Flächengebilde gleitflächenseitig bis zu einer Eindringtiefe zwischen 0,5 mm und 5 mm, vorzugsweise zwischen 1 mm und 2 mm mit dem Polymer behandelt ist.

As particularly advantageous has been found when

• - The textile fabric has a thickness between 2 mm and 10 mm, preferably between 3 mm and 7 mm, most preferably 5 mm, and / or
• - The fabric is treated sliding surface side to a penetration depth between 0.5 mm and 5 mm, preferably between 1 mm and 2 mm with the polymer.

It is advantageous if the penetration depth and, in the case of a two-sided impregnation, the sum of the two penetration depths is less than the thickness of the textile fabric or the felt.

As a result, the original structure of the layer below the layer treated with the polymer or the layer between the two layers treated with the polymer is largely retained, so that the resilient effect of the furniture glider is maintained despite the impregnation. The resilient effect is particularly advantageous when the furniture glides on chairs, especially chairs for schools, is used.

• – einen Behandlungsschritt, in dem ein textiles Flächengebilde mit einer Gleitfläche und einer der Gleitfläche gegenüberliegenden Montagefläche für eine vorbestimmte Behandlungsdauer einer Behandlung unterzogen wird, bei der das textile Flächengebilde zumindest gleitflächenseitig mit einem Polymer behandelt wird,
• – einen Trocknungsschritt, der nach dem Behandlungsschritt durchgeführt wird, wobei in dem Trocknungsschritt das mit dem Polymer behandelte textile Flächengebilde thermisch behandelt wird, wobei während der thermischen Behandlung das mit dem Polymer behandelte textile Flächengebilde auf eine für die Anwendung des Möbelgleiters gewünschte Stärke gebracht wird, und
• – einen Nachbearbeitungsschritt, der nach dem Trocknungsschritt durchgeführt wird, wobei in dem Nachbearbeitungsschritt aus dem thermisch behandelten textilen Flächengebilde der Möbelgleiter entnommen wird.

The invention further provides a method for producing a furniture glider, in particular a furniture glider according to the invention, the method comprising:

• A treatment step in which a textile fabric having a sliding surface and a mounting surface opposite the sliding surface is subjected to a treatment for a predetermined treatment duration, in which the textile fabric is treated with a polymer at least on the sliding surface side,
• A drying step carried out after the treatment step, wherein, in the drying step, the polymer-treated fabric is thermally treated, wherein during the thermal treatment the polymer-treated fabric is brought to a desired strength for the application of the furniture glider, and
• A post-processing step carried out after the drying step, wherein in the post-processing step the furniture glider is removed from the thermally treated textile fabric.

Prior to the treatment step, a manufacturing step may be performed in which the fabric is made by blending and compacting wool fibers into a felt. The felt is preferably compressed so that on the one hand good polymer uptake is ensured in the subsequent treatment step and on the other hand the felt already has a thickness which largely corresponds to the desired thickness for the application of the furniture glider.

In the treatment step, the textile fabric can pass through a PTFE bath in order to impregnate and / or impregnate at least one sliding surface-side layer of the textile fabric with polytetrafluoroethylene (PTFE).

Instead of a PTFE bath, the polytetrafluoroethylene can also be applied in the spray process on the sliding surface side surface of the fabric to impregnate at least the sliding surface side layer of the textile fabric with polytetrafluoroethylene.

The treatment time in the treatment step is preferably selected such that the sliding surface-side penetration depth of the polymer or PTFE into the textile fabric is between 0.5 mm and 5 mm, preferably between 1 mm and 2 mm.

In one embodiment of the method according to the invention, it may be provided in the drying step to pressurize the polymer-treated textile fabric in order to bring the textile fabric to the desired thickness for the application of the furniture glider, wherein the pressure is preferably selected such that the thickness is between 2 mm and 10 mm, preferably between 3 mm and 7 mm, very particularly preferably 5 mm.

The furniture glides can be removed by punching or cutting from the thermally treated textile fabric.

The invention further provides a piece of furniture, in particular a chair, with furniture glides according to the invention arranged on the bottom side. On the chair, the furniture glides can be arranged on the undersides of the chair legs.

Brief description of the figures

Further details and features of the invention, in particular advantageous embodiments will become apparent from the following description taken in conjunction with the drawings. It shows:

1 a detail of a furniture slider according to the invention in a sectional view;

2 a lower portion of a chair leg with a furniture slider according to the invention arranged thereon; and

3 a stopper with a furniture slider according to the invention arranged thereon.

Detailed description of the invention

1 shows a section of a furniture slider according to the invention 1 in a sectional view and in a ready-to-use state.

The furniture glider 1 has a textile fabric 4 on. The textile fabric 4 may have felt, especially wool felt. However, fibers other than wool fibers may be used to make the felt. To make the felt, the wool fibers, or other fibers suitable for making a felt, may be mixed and compacted into a felt, such as by wet felting or dry felting.

The textile fabric 4 or the felt is made in a thickness which is slightly larger than the thickness or thickness d1 desired for the application of the furniture glider. The felt is thus only compressed so far that even a good absorption of the impregnating agent is ensured by the outer layers of the felt and the impregnating agent can penetrate to the desired depth d2 of the felt.

The textile fabric 4 or the felt has a sliding surface 2 and a mounting surface 3 on. When assembled, the sliding surface 2 the underground, such as floor, and the mounting surface 3 facing the furniture.

After making the felt 4 , which may have a thickness of about 6 mm to 7 mm in this state, is fed to the felt or felt plates present felt to a treatment step. In this treatment step, the felt is treated at least on the sliding surface side with a polymer. The polymer used here is polytetrafluoroethylene (PTFE), which has proven to be particularly advantageous in terms of sliding properties and low dust and moisture absorption and in terms of good abrasion resistance.

The felt or the felt panels go through in the treatment step, a PTFE bath, wherein at least one sliding surface side layer 5 of the felt is immersed in the PTFE bath. The treatment time in the PTFE bath is chosen so that the PTFE can penetrate into the felt down to a depth d2. With a greater density of the felt to be treated, it may therefore be necessary to increase the treatment time, with a lower density of the felt, the treatment time can be optionally reduced. In addition, the duration of treatment can be adjusted depending on the capillary action of the felt material.

It is advantageous if the penetration depth t2 is smaller than the depth or thickness d1 of the felt. This can be avoided that the mounting surface side layer 6 or the mounting surface 3 also impregnated. This is advantageous if the ready-made furniture glides are to be attached to the furniture on the mounting surface side with an adhesive. Because by a mounting surface side impregnation of the furniture slider with PTFE, the adhesive effect of the adhesive on the mounting surface 3 be reduced.

After the felt (s) have been treated in the PTFE bath and the slip surface side layer 5 has been impregnated with the PTFE, the felt is fed to a drying step or a drying process.

In the drying process, the impregnated and still wet felt is thermally treated on the one hand, i. dried. For this purpose, a drying device, such as a drying oven can be used.

On the other hand, in the drying process, the felt is brought to the desired thickness d1 for the application of the furniture glider, for example by applying pressure to the felt, for instance by means of a pressing device. The plates of the pressing device can be heated to simultaneously dry the felt. From the original thickness of about 6 mm to 7 mm, the impregnated felt is brought to a ready-to-use thickness d1 of about 4 mm to 5 mm, wherein the felt on the sliding surface side to a depth d2 of about 1 mm to 2 mm treated with PTFE or impregnated.

By pressing in the drying process also a uniform and even smoother surface of the sliding surface 2 reached.

Above, for the treatment step and for the drying step, the impregnation of the sliding surface side surface or layer 5 the felt or furniture glider have been described.

According to the invention but also the mounting surface 3 or the mounting surface side layer 6 treated with PTFE or impregnated. The procedure here corresponds to the procedure described above for the treatment or impregnation of the sliding surface 2 or the sliding surface side layer 5 ,

The mounting surface 3 or the mounting surface side layer 6 can be treated or impregnated especially with PTFE, if the furniture glider is not attached to the furniture with an adhesive but with other fasteners, such as screws or nails.

Be both sides 2 . 3 or the two outer layers 5 . 6 PTFE treated or impregnated, the treatment step in which the felt is placed in the PTFE dip can be carried out separately for each side. Alternatively, the felt can also be completely immersed in the PTFE bath, so that both sides can be treated or impregnated simultaneously in one step.

In a two-sided impregnation of the felt or the furniture glides, it may be advantageous to choose the penetration depth d2 so that the sum of the two penetration depths is smaller than the thickness or thickness d1 of the furniture glides. The thickness d1 of the furniture glider 1 can be about 5 mm, the penetration depth can be about 2 mm, a total of 4 mm. Between the two impregnated layers 5 . 6 This leaves a non-impregnated layer. The structure of the felt layer between the two layers treated with the PTFE 5 . 6 remains so largely preserved, so that despite the impregnation, the resilient effect of the furniture glider is maintained. This also applies to the one-sided impregnation, in which the penetration depth d2 is smaller than the thickness d1 of the furniture glider.

The resilient effect is particularly advantageous when the furniture glides on chairs, especially chairs for schools, is used. It has a positive effect on the sitting experience of the user.

In a last step, the post-processing step, are made from the impregnated fabric 4 or from the impregnated felt the furniture glides 1 taken. This can be done for example by means of punching or cutting, such as laser cutting. The punched out or cut out furniture glides are now ready for use and can be attached to the furniture.

2 shows a lower portion of a chair or table leg 10 , at the bottom of an inventive furniture glides 1 is arranged.

At the in 2 shown furniture glides 1 is only the sliding surface side layer 5 impregnated with PTFE. The mounting surface side layer is not impregnated, so that in 2 shown furniture glides, with an adhesive on the underside of the chair or table leg 10 to be attached.

The in 2 shown furniture glides 1 is with a nail on the underside of the chair or table leg 10 attached. Other fasteners, such as screws, may be used.

Because the mounting surface side layer of the furniture glider 1 is not impregnated, the resilient property of the felt is preserved in this layer.

3 shows a stopper 12 with a furniture glider according to the invention arranged thereon 1 , The stopper 12 can be inserted with an upper portion in a conventional manner in a bottom open chair or table leg. The lower, bottom-facing portion of the plug 12 has a recess in which the furniture glider 1 inserted and / or pressed. The furniture glider 1 can be glued to the walls of the recess to prevent loosening of the furniture glides.

The furniture glider 1 protrudes in the axial direction at the bottom of the plug, so that only the protruding portion of the furniture slider comes into contact with the ground, such as the floor.
