Definitions

  • the present invention relates to a piece of furniture, in particular seating furniture, with a base part on which a movable furniture part is pivotably mounted via at least one pivoting fitting, the at least one pivoting fitting being fixed to the base part with a first lever and with a second lever attached to the first lever pivotably arranged lever is fixed to the movable furniture part, the second lever being fixed to a shaped body which is provided with a large number of hollow chambers and forms a core of the movable furniture part and a pocket for receiving at least part of the second lever is formed in the shaped body, and methods of assembling a piece of furniture.
  • the DE 10 2015 113 749 A1 discloses a swivel fitting for an upholstered piece of furniture, in which two levers are rotatably mounted relative to one another, the two levers being able to be continuously fixed in different angular positions relative to one another via a clamping mechanism. This enables flexible use of the swivel fitting for armrests, footrests, siderests or other movable furniture parts.
  • swivel fitting is in the DE 10 2017 110 253 A1 shown, which also comprises two relatively rotatable levers that can be fixed in different angular positions via a clamping mechanism for fixing the lever.
  • the clamping mechanism includes at least one pawl and a pinion.
  • the U.S. 5,375,914 discloses a piece of seating furniture in which a swivel fitting is fixed with a lever in a lateral receptacle of the seat part. To do this, screws are screwed into the lever and the seat part from the side.
  • EP 2532 275 discloses a swivel fitting with two levers that are fixed to a piece of furniture.
  • Movable furniture parts usually consist of a wooden board as a carrier element for foam materials, a layer of wadding and upholstery fabrics. The swivel fittings are then screwed to these wooden boards using screws on the drive-in nuts previously introduced in the wooden board.
  • this known structure is inflexible with regard to the design of the furniture part and, on the other hand, it requires very complex production steps, such as the gluing of foam materials.
  • the second lever of the swivel fitting is fixed to a shaped body which is provided with a multiplicity of hollow chambers and forms a core of the movable furniture part.
  • This shaped body is pivotably mounted on one or more pivoting fittings and, depending on the application, can have different shapes, with a low intrinsic weight being present due to the provision of hollow chambers.
  • the shaped body can consist of a single material, in particular plastic, and fillers can also be added to the plastic, such as fibers containing lignocellulose, recycled fibers made of plastic or cotton, or substances in powder form.
  • a pocket for receiving at least part of the second lever is formed in the shaped body.
  • the second lever can then be partially or fully inserted into the pocket and is preferably fixed there by clamping or latching.
  • the shaped body can be mounted on the second lever without the use of tools.
  • corresponding clamping contours such as a wedge-shaped clamping contour, or a bendable latching web with a projection that engages in a recess on the lever can be formed on the pocket.
  • the connection can either be permanent or also be designed to be detachable, for example by the flexible latching web being lifted out of the form-fitting engagement again by means of a release lever.
  • the shaped body preferably has a stiffening structure formed from webs, the webs surrounding the hollow chambers.
  • the molded body can be made in one piece or composed of several individual parts.
  • the assembly from individual parts has the advantage that the shaped body can be assembled in different lengths or widths, depending on the application.
  • the shaped body can advantageously have areas with a higher ridge density and areas with a lower ridge density.
  • greater resilience of the shaped body can be achieved through a lower web density, which increases the support comfort.
  • a higher web density is very advantageous for stiffening.
  • a slot is formed on the shaped body, through which the first lever is passed.
  • the slot can extend over a predetermined angular range on a rounded edge of the shaped body in order to be able to pivot the shaped body relative to the first lever.
  • the shaped body preferably has a smooth surface on two opposite sides.
  • This surface can serve as a support, with a different elasticity preferably being present on the surfaces due to the shaping of the shaped body.
  • One surface can be designed to be more elastic, that is to say it can deform more elastically than the other surface under a predetermined contact pressure. This allows you to specify which surface is used as a support surface and which surface is used as an elastic surface. This can be done by adjusting the stiffening structure, resulting in higher stiffness on one side than the opposite side.
  • the shaped body or its individual parts are preferably produced by injection molding, extrusion or 3D printing.
  • the proportion of hollow chambers in the shaped body, based on the total volume, can be more than 50%, for example between 60% and 95%. This allows the molding have a relatively low dead weight and already form the geometry that the movable furniture part is supposed to occupy approximately.
  • the shaped body can form the movable furniture part directly, ie it can be accessible from the outside.
  • a flexible cover is preferably applied around the shaped body.
  • Such a flexible cover can be, for example, a cover made of leather, a textile material or an elastic plastic, which forms the outer surface of the movable furniture part.
  • a further component can optionally also be fixed to the shaped body, such as a display with a screen, an operating unit and/or a controller, for example if a medium or an application is to be integrated into the movable furniture part.
  • a corresponding receptacle can be formed on the shaped body for this purpose.
  • the movable furniture part can be pivotably mounted on the base part via two or more pivoting fittings.
  • the movable furniture part can be designed as an armrest, footrest or headrest.
  • the base part can be, for example, a seat of an upholstered piece of furniture or a vehicle seat. Furthermore, the base part can also be a treatment chair on which a movable furniture part is pivotably mounted.
  • the shaped body can preferably have a low intrinsic weight without a swivel fitting, for example less than 350 g, in particular between 50 g and 250 g.
  • the shaped body can be used with the swivel fitting for different applications, especially in vehicles.
  • the term "furniture” should therefore not be understood in a restrictive manner, but should also include shelves, armrests or other movable components that are built into vehicles or ships or airplanes.
  • a base part is provided, on which a first lever of a swivel fitting is fixed.
  • a second lever of the swivel fitting is inserted into a molded body that has a large number of hollow chambers and is produced by injection molding, extrusion or 3D printing. This simplifies the assembly of the molded body, since it is simply attached to one or more levers.
  • the shaped body can then optionally be surrounded with a flexible cover to complete the furniture.
  • swivel fittings can be used in the configuration according to the invention.
  • other swivel fittings can also be used, for example, which, in addition to the swiveling movement, enable translational movements of the second lever relative to the first lever, as is the case, for example, with DE 20005850U or the DE202008001323U1 the case is.
  • the second lever can then also be designed as a lever that can be moved in a translatory manner relative to the swivel fitting, or as an angle piece. In these cases, the pivoting takes place by means of a rotation or a combination of rotation and translation.
  • swivel fittings in which the swiveling takes place by means of a different mechanical principle, such as that of a four-bar linkage or a multi-bar mechanism.
  • the invention can also relate to a piece of furniture, in particular a piece of seating furniture, comprising a base part and at least one furniture part which is connected to the base part via a movement fitting or a connecting fitting, the furniture part consisting of a Molded body provided with hollow chambers, which forms a core of the furniture part.
  • the molded body can be designed according to the exemplary embodiment shown below, but without the swivel fitting.
  • the movement fitting can be designed as a linear guide, pull-out guide or sliding fitting.
  • the shaped body can also be used for displaceable headrests or other furniture parts.
  • This invention can also be used with rigid furniture parts, so that the shaped body is only fixed via a connecting fitting, for example in a fixed back part. Then, for example, the straps that are stapled to the back parts could be omitted. Furthermore, the foam and the cotton would also be omitted here.
  • a further exemplary embodiment would also be the use of the invention in a seat part of a piece of furniture.
  • the furniture part with the shaped body can be screwed to a body or attached to the body.
  • a piece of furniture 100 is designed as a piece of seating furniture and includes a base part 104 which has a seat and a frame for supporting or fastening the base part 104 .
  • the piece of furniture 100 shown schematically has a movable furniture part 101 which is designed as a pivotable head part and is connected to a backrest of the base part 104 via one or more pivoting fittings 1 .
  • a movable furniture part 102 is provided as a side part on opposite sides, which is also connected to a frame of the base part 104 via one or more swivel fittings 1 .
  • Another movable furniture part 103 is designed as a foot part and is connected to the base part 104 via one or more swivel fittings 1 .
  • a first lever 2 of a swivel fitting 1 is fixed to the base part 104, while a second lever 3, which is pivotably mounted on the first lever 2 and can be fixed in different angular positions, is fixed to the movable furniture part 101, 102 or 103 set.
  • the piece of furniture 100 can be designed as upholstered furniture, such as an armchair, sofa, bed, but also as a vehicle or aircraft seat or as a treatment chair.
  • the movable furniture parts can also be used in mobile homes, ships or other vehicles.
  • a shaped body 4 which forms a core of a movable furniture part 101, 102 or 103 and two swivel fittings with the Base part 104 is connected.
  • the shaped body 4 consists of a large number of individual parts 40, 41 and 42 which are combined to form a unit.
  • the individual parts 40, 41 and 42 can be plugged into one another, fixed to one another by fastening means or glued together.
  • a slot 43 is formed on the shaped body 4 in the region of the pivoting fitting 1, through which the first lever 2 of the pivoting fitting 1 is passed.
  • the shaped body 4 is shown in section.
  • the shaped body 4 comprises a multiplicity of hollow chambers 7 which are surrounded by webs 8 of a stiffening structure.
  • the webs 8 of the stiffening structure can be arranged in a truss-like manner in order to support the shaped body 4, the shaped body 4 having a substantially smooth surface 5 and 6 on opposite sides, respectively.
  • the surfaces 5 and 6 are supported by the stiffening structure formed from webs 8 .
  • the proportion of the hollow chambers 7 based on the total volume of the shaped body 4 is over 50%, for example between 70% and 95%. In this respect, the shaped body 4 can be produced with a large volume and low weight.
  • the molded body 4 or the individual parts 40, 41 and 42 of the molded body are preferably produced by injection molding, extrusion or 3D printing.
  • Two pockets 20 are formed on the shaped body 4 and have a cross-sectional geometry that essentially corresponds to the cross-sectional geometry of the lever 3 .
  • the lever 3 is plate-shaped, and the pockets 20 are correspondingly provided with a rectangular cross-section.
  • the lever 3 can be fixed in a clamping or latching manner on the pockets 20 of the shaped body 4, so that assembly without the use of tools is possible.
  • the lever 3 can also be glued or screwed to the shaped body 4 .
  • the lever 3 can also have a different geometry, for example it can be designed as an L-shaped angle piece, in which case the pocket 20 also has a corresponding geometry.
  • Each item 40 includes connecting means 9, which are designed as thickened strips, the holding means 10 of an adjacent item 40, 41 or 42 can be fixed by latching, static friction or insertion.
  • the holding means 10 are designed, for example, as a groove which encompasses the connecting means 9 .
  • These connecting means 9 and holding means 10 are provided both between the individual parts 40 and between the individual parts 41, the individual parts 41 being arranged at the edges.
  • a groove 16 delimited by webs is formed on the end face of the individual parts 41, in which further components can be fixed, for example a seam of a flexible cover for the shaped body 4. Slots are also formed between the individual parts 40 in the region of the surface 5.
  • the slit-shaped grooves 16 serve to increase the mobility of the individual part 40.
  • the surfaces 5 and 6 have different elasticity when a contact pressure is applied.
  • the reason for this is that the stiffening structure of the webs 8 in the area adjacent to the surface 5 is designed differently than adjacent to the surface 6.
  • An additional reinforcement web 11 is provided adjacent to the surface 6, which is missing adjacent to the surface 5.
  • the surface 5 is designed to be more elastic than the surface 6 when contact pressure is applied, which can be used, for example, to optimally adapt the spring properties on the surface 5 to the intended use.
  • FIG 4 the shaped body is shown in a view during assembly.
  • the two swivel fittings 1 comprise the two levers 2 and 3, which are rotatably mounted about an axis 12 and can be fixed in different angular positions to one another, as is shown in FIG DE 10 2017 110 253 A1 and DE 10 2015 113 749 A1 is revealed.
  • the swivel fitting 1 shown in the exemplary embodiment is only an example. Other types of pivot fittings or pivot fittings with additional linear motion can also be used.

  • two central individual parts 40 are provided, which can be fixed to one another by inserting the connecting means 9 on the holding means 10, with the number of individual parts 40 in the central area being able to be varied depending on the application in order to increase the length of the molding 4 to change.
  • items 42 are provided on the longitudinal edges of the molded body, which are arranged at the edge.
  • the two Individual parts 42 on the side of the swivel fittings 1 include the slot 43 for carrying out the lever 2 in the area of a rounded edge.
  • the slot 43 or clearance is needed to allow the pivot fitting 1 to pivot. Due to the pivoting, the lever 2 needs a free space, since it would otherwise strike the individual part 42 .
  • Items 42 are also provided on the opposite side, which are fixed to items 40 and 41 via plugs 13 and 14 .
  • the plugs 13 and 14 have a cross-sectional contour which is adapted to the contour of the hollow chambers 7 on the individual parts 40 and 41, so that the plugs 13 and 14 can be fixed to the individual parts 40 and 41 in a clamping manner.
  • the plugs 13 and 14 can also be glued or screwed to the individual parts 40 and 41.
