Definitions

  • the present invention relates to a floor protector for a piece of furniture with a floor assembly and a chair with at least two floor protectors.
  • Floor protectors are used for different applications.
  • floor protectors can be attached to the feet of general furniture, such as shelves and cupboards, so as not to scratch a surface when moving the furniture.
  • Such floor protectors or furniture protectors can be designed, for example, as simple glued-on felt feet. If, on the other hand, furniture is to be moved on carpeted floors, sliding elements are preferably provided. These can be designed as roles, for example.
  • a movable floor protector is, for example, in the DE 1 429 499 C shown.
  • a sliding body with a convexly curved bottom surface is disclosed, which can be connected to a stand of the piece of furniture via a pin.
  • the sliding body has a blind hole in which the pin is rotatably mounted. Via the convexly curved floor surface, the pieces of furniture can be pushed over carpet surfaces without excessive expenditure of force, the sliding body being able to align itself according to a direction of displacement.
  • floor protectors In the area of seating furniture, such as chairs with an essentially tubular floor assembly, floor protectors are known which are attached to a lower part of the tubular frame the floor pan can be arranged. Such floor protectors should, in particular, allow the seating furniture to be moved without damaging the surface, with abrasion of the surface, for example in the form of scratches or pressure marks, to be avoided. At the same time, when the chair is under load, the floor protector should allow it to adhere to the surface so that the seating furniture does not slip in the loaded state. The same applies to seating furniture, such as chairs with individual chair legs.
  • the pamphlet DE 10 2010 039 292 B4 shows a floor protector for a chair with a tubular floor assembly.
  • the chair is preferably designed as a cantilever chair with a Z-shaped basic shape.
  • the floor protector has an opening with which it radially encloses the ends of the floor assembly.
  • the surface of the floor protector facing the subsurface is flat.
  • the floor protector has two components with different hardnesses, one of the components being in contact with the ground. This component can be formed from a thermoplastic decree to more, and know a recess for receiving a floor glider, for example made of felt material or plastic.
  • the floor protectors must have a sufficiently rough or adhesive surface. However, this has a negative effect on a state into which the chair is moved across a surface. A sticky or rough surface leads to scratching of the surface and should therefore be avoided.
  • the present invention is based on the object of specifying an improved floor protector for seating furniture.
  • this object is achieved by a floor protector with the features of claim 1 and a chair according to claim 15.
  • the knowledge / idea on which the present invention is based is that a contact surface between the Floor protectors and the subsurface to be adapted to the different states of load or movement of the chair.
  • the floor protector provides different contact surfaces to a sub-floor, depending on whether the piece of furniture is loaded or unloaded, by means of at least two elements that are movable relative to one another.
  • the sliding element In the unloaded state, only the sliding element is preferably in contact with the base, so that the chair can slide without damaging the base when the chair is moved.
  • the base body In a loaded state, on the other hand, or in addition preferably, the base body is in contact with the substrate, so that adhesion to the substrate is made possible.
  • the sliding element can therefore preferably move in the direction of the ground, so that the sliding element provides a contact surface between the floor protector and the ground.
  • the base body can be designed to be elastic in at least one partial area or it can comprise a spring element.
  • the underside of the base body can thus be in full-surface contact with the subsurface by deformation of the spring element or the partial area, so that adhesion to the subsurface is made possible.
  • the floor protector is designed at the same time as a slider element and as a stopper element.
  • the seating furniture has, for example, two essentially U-shaped chair legs that move away from each other from the seat surface towards the ground, for example diverge conically, when the seating furniture is loaded, shear forces occur parallel to the ground between the floor protectors and the surface of the ground.
  • a floor protector with sufficiently high adhesive properties can prevent the U-shaped chair legs from spreading further due to the load.
  • the floor protector can have different designs, for example it can be adapted to the size and geometry of the floor assembly. For example, a width or length can be adapted to a width or length of a tubular floor assembly.
  • the floor protector can preferably be arranged on an underside of the floor assembly, for example screwed, clipped on or glued on.
  • the floor protector is only connected to the floor assembly from one surface side, for example attached to a tubular element or a differently shaped hollow profile from one side.
  • At least one floor protector can be arranged on a contact surface between the floor pan and the subsurface.
  • at least two floor protectors can be provided at a distance from one another if the contact surface between a stand of the chair and the base is at least linear. This corresponds, for example, to an embodiment in which two U-shaped chair legs are provided.
  • the seating furniture can be provided with differently designed floor groups, which can consist, for example, of individual or also in pairs U-shaped chair legs.
  • the outer surface of the sliding element in an unloaded state of the chair, can protrude at least in sections beyond the bottom of the base body.
  • the outer surface of the sliding element is advantageously designed as the only contact surface between the substrate and the floor protector or seating furniture.
  • the outer surface of the sliding element can be specially designed to slide on the surface as possible without damaging the surface when the seating furniture is moved along the surface.
  • the sliding element and / or the partial area can be arranged in an unloaded state in a first position and in a loaded state in a second position, the sliding element and the partial area being self-resettable from the first position to the second position.
  • a change between a configuration in which a contact surface between the sliding element and the base and a contact surface between the base body and the base are formed is possible without manual operation on the floor protector.
  • the base body, or the base body and the sliding element can preferably be in contact with the ground. This allows a contact area with sufficient Adhesion to the subsurface.
  • the sliding element can move vertically within the recess in such a way that only the sliding element is in contact with the ground. This is achieved, for example, in that the sliding element moves vertically in the direction of the ground.
  • the sub-area of the base body can also be deformed in such a way that an outer surface of the base body is displaced. Contact between the base body and the ground can be avoided in this position. As a result, there is a contact surface between the sliding element and the ground, which can have sliding properties.
  • the sliding element can act as a kind of runner. In this unloaded state, the seating furniture can consequently be moved easily and without adhesive forces on the ground.
  • the sliding element can be mounted in the recess via at least one spring.
  • a self-resetting effect is advantageously possible in this way.
  • the spring forces can move the sliding element out of the recess in the unloaded state in the direction of the substrate in such a way that the sliding element protrudes in the direction of the substrate beyond the underside of the base body at least in sections.
  • the sliding element and / or the base body can consist of a thermoplastic elastomer (TPE / TPU).
  • TPE / TPU thermoplastic elastomer
  • the sliding element and / or the base body can be an injection molded component.
  • a two-component component from the base body and at least one sliding element can be produced in combination in this way, with different geometries and undercuts of the sliding element and / or the base body being able to be formed.
  • the formation of different recesses is also possible in a simple and flexible manner. Materials with different hardness and different surface properties can be used, which preferably have different frictional resistances in order to form a type of stopper element and slide element.
  • a frictional resistance of the outer surface of the sliding element can be smaller than a second frictional resistance of an outer surface of the underside of the base body.
  • the sliding element can advantageously have sliding properties and the base body can have adhesive or non-sliding properties.
  • the sliding element can be flat on the outer surface. This advantageously enables full-surface contact between the sliding element and the subsurface. As a result of the full-surface contact, scratching of the substrate can advantageously also be avoided.
  • the recess can have a length which corresponds to 1/3 to 2/3 of a length of the base body.
  • the sliding element is not visible from a position outside the base body when the base body rests on a surface.
  • the recess preferably runs on or within the underside of the base body. It is also conceivable that two or more recesses are arranged on the underside of the base body are, for example, equally spaced and formed with the same length. As a result, a floor protector with several sliding elements can be formed.
  • two sliding elements can be arranged in the recess or in two recesses.
  • Two sliding elements are preferably arranged in two recesses.
  • the two recesses can be arranged one behind the other on the underside of the sliding element and have the same geometry.
  • a sliding element can be arranged in each of the recesses, the two sliding elements being able to move independently of one another.
  • the base body is convex on the underside in an unloaded state, the convex area forming the elastic partial area and / or the spring element.
  • the convex area can advantageously be deformed in such a way that the underside of the base body is flat.
  • the convex area can be shifted vertically for this. This can be achieved by a slot or a recess which is arranged above the convex area and within the base body.
  • the base body can be flat on the underside and / or on the top side.
  • the floor protector can thereby advantageously be arranged below the floor pan in a particularly space-saving manner. If the underside is flat, the sliding elements are preferably mounted in the recess via springs.
  • the base body can have a thread on the upper side, so that the floor protector can be connected to the floor assembly of the chair via a connecting element. This way the floor protector can can be flexibly assembled and disassembled. Individual floor protectors can thus be easily exchanged.
  • the base body can have a clip element on the upper side, so that the floor protector can be clipped onto the floor assembly of the chair.
  • the floor protector can advantageously be installed in a particularly space-saving manner and without loss of appearance.
  • Fig. 1 shows an isometric view of a floor protector 1 according to one embodiment.
  • the floor protector 1 consists of a base body 4 and two sliding elements 8.
  • the sliding elements 8 are each arranged in a recess 7 in the base body 4.
  • the two sliding elements 8 are arranged one behind the other in the base body 4.
  • the two recesses 7 are made on an underside 6 of the base body 4.
  • an outer surface 9 of the sliding element 8 is arranged on the same side as an outer surface 14 of the base body 4.
  • at least one of the two outer surfaces 9, 14 can come into contact with a substrate (not shown).
  • Fig. 2 shows a side view of the floor protector 1 according to Fig. 1 .
  • the base body 4 has a slot 17 in the area of the underside 6, so that a partial area 16 is created below the slot 17, which is designed as a spring element 15.
  • the sub-area 16 or the spring element 15 is convex on the underside 6.
  • the floor protector 1 In the state shown in Fig. 2 the floor protector 1 is in the unloaded state in a first position P1, in which only a small portion of the convex underside 6, which is located on the axis of symmetry of the base body 4, is in contact with the ground.
  • the outer surfaces 9 of the sliding elements 8 are flat and can thus be in full-surface contact with a substrate.
  • the outer surfaces 9 of the sliding elements 8 can have a frictional resistance R1, which enables the outer surface 9 to slide on the ground. It would also be conceivable that the underside 6 of the base body 4 does not touch the ground in this first position P1.
  • the floor protector is 1 in Fig. 2
  • the partial area 16 is deformed or deformed in such a way that the slot 17 is closed.
  • the entire lower side 6 of the base body 4 can come into contact with a substrate, since the lower side 6 is essentially flat in this loaded state.
  • the underside 6 has a corresponding frictional resistance R2> R1, an adhesive surface can be formed as a result. In this loaded state, a piece of furniture (not shown here) can adhere to a surface.
  • Fig. 3 shows a sectional view of the floor protector 1 along the plane BB in FIG Fig. 2 . It can be seen that in this embodiment the outer surface 14 of the base body 4 is arranged on the axis of symmetry at ground level with the outer surface 9 of the sliding elements 8. On an upper side 5, the base body 4 has grooves with which the floor protector 1 can be connected to a floor assembly (not shown here).
  • Fig. 4 shows a further sectional view of the floor protector 1 according to Fig. 1 .
  • the cutting plane lies within the recesses 7, so that these are visible one behind the other in the base body 4.
  • a thread 11 can be seen in the central area, and in combination with a connecting element (not shown) the floor protector 1 can be connected to the floor assembly of the chair (not shown).
  • Fig. 5 shows a sectional view of the floor protector 1 along the plane AA in FIG Fig. 4 .
  • the geometry of the sliding elements 8 can be seen here.
  • the sliding elements 8 have undercuts with the base body 4.
  • An injection molding process in particular a two-component injection molding process, is therefore preferably used to produce the floor protector 1.
  • the base body 4 and the sliding elements 8 can be made from a thermoplastic elastomer.
  • An inexpensive manufacturing process is provided by an injection molding process. It is also conceivable to glue or clip the two sliding elements 8 to the base body.
  • the sliding elements 8 are flat on the outer surface 9 and can therefore be in full-surface contact with a substrate.
  • there is only a small area of the outer surface on the axis of symmetry of the base body 4 14 of the base body 4 is arranged at the level of the outer surfaces 9 of the sliding elements 8.
  • the floor protector 1 is designed as a slider or slider element, whereby a piece of furniture with such floor protectors 1 can slide on a sub-floor in this unloaded state without impairing the sub-floor, similar to a runner.

  • Fig. 7 shows a seating furniture 2 with four floor protectors 1.
  • the seating furniture 2 is designed as a chair 12.
  • a cantilever chair is shown, which has a coherent and tubular structure as floor pan 3.
  • Two floor protectors 1 are arranged on two sections of the tubular structure. These are only shown schematically in this illustration. If the chair 12 is loaded in the vertical direction v, the floor protectors 1 behave as in relation to Fig. 2 described. A load on the chair 12 occurs, for example, when a person sits on it. In such a loaded state, the floor protectors 1 deform to a second position P2, in which the floor protectors 1 are designed as adhesive elements.
  • the floor protectors deform 1 back to a first position P1, as in Fig. 2 shown.
  • the floor protectors 1 are designed as sliding elements. This is made possible by the fact that the partial area 16 of the base body 4 is designed to be self-resettable into the first position P1. Consequently, the advantages of the floor protector 1 can already be achieved when a person rises from the chair 12 for a short time, for example, in order to bring the chair 12 closer to a table or the like. to move.
  • Fig. 8 shows another chair 12 with four floor protectors 1.
  • the floor assembly 3 of the chair 12 has two U-shaped foot elements, two floor protectors 1 being arranged on each U-shaped foot element.
  • the U-shaped foot elements can move away from one another, starting from the seat surface towards the base 13, these being arranged conically, so to speak. This creates shear forces between the floor protectors 1 and the subsurface 13 in the loaded state. Since the floor protectors 1 are designed as stopper elements in the loaded state and therefore adhere to the substrate 13, these shear forces can be largely absorbed by the floor protectors 1. As a result, the floor protector 1 can improve the stability of the chair 12.
  • the sliding elements 8 can be arranged or mounted within the recess 7 such that they can be displaced in the vertical direction v. This can also make it possible for the outer surface 9 of the sliding elements 8 to be connected to the ground in an unloaded state 13 is contacted. In such an embodiment, in a loaded state, the sliding elements 8 are displaced in the vertical direction v. The sliding elements 8 move into the base body 4, so to speak, so that, in the loaded state, the outer surface 14 of the base body 4 can be in contact with the substrate 13. In order to achieve a self-resetting effect of the sliding elements 8, springs 10 can be attached to the in Fig. 5 positions shown are arranged. Such an embodiment is quasi the inverse of that in FIGS Figs. 1 to 6 illustrated embodiments formed. It is essential in each of the embodiments that at least a partial area of the base body 4 and the sliding element 8 can move relative to one another. In each of the described embodiments, only one sliding element 8 can be arranged in the base body 4.
