Definitions

  • the invention relates to a chair with four legs, a seat, a backrest, a frame part connecting the legs and supporting the seat, the backrest being fastened to the rear legs projecting upwards beyond the seat.
  • the leg frame In a chair known from DE-OS 32 24 812, the leg frame is bent from specially profiled tubes. Connected parts attached to it carry the seat and the backrest.
  • This construction which is advantageous in terms of manufacturing technology for the design that is possible, is tied to the use of profiled bars for the entire leg frame, which, if appropriate with appropriate inserts, also offer sufficient stability in the bending area.
  • the overall shape is determined by the leg frame, but also limited.
  • the invention has for its object to propose a chair in which straight semifinished elements, such as metal tubes or wooden rods, can be used for the legs, which allow different combinations depending on the stability needs and the design requirements and the rods can be made continuously, however interact with a suitable support structure for connecting the legs and carrying the seat, and which enables favorable manufacturing conditions in series production even with different colors or material combinations.
  • straight semifinished elements such as metal tubes or wooden rods
  • a chair has at least the following features: - four legs; - a seat; - a backrest; - a frame part connecting the legs and supporting the seat; - The seat is preferably held at a distance above the frame part; - The backrest is attached to the rear legs, which rise above the seat; -
  • Each of the legs is formed from at least two straight, cylindrical, directly adjacent round rods; -
  • the frame part has protruding leg connection arms; - The connection ends of the leg connection arms each extend into the inwardly facing recesses between the two round rods of each leg; - They are connected with the legs to absorb the supporting, bending and torsional forces.
  • the straight legs formed from at least two round bars can now run through and by simple Clipping be formed. You do not need to be inserted into corresponding cylindrical sleeves of a frame and connecting part and adapted accordingly. So you are much freer in the choice of design and appearance and can achieve much slimmer legs with great stability thanks to the double round bars. You can now use materials for the legs, such as those used in bent semifinished legs, for example according to DE-OS 32 24 812 or in the rattan chairs made of naturally grown round bars or in chairs made of thin round steel bars, such as were used for coffee house chairs , were not suitable.
  • connection between the leg and the frame part takes place in the inner area between two round bars, depending on the strength requirements, a length can be chosen for the connection that is independent of the round bar diameter and that even with interesting design variants with straight, multi-bar Legs or round rod legs combined into bundles enable sufficient attachment at the most critical point even with difficult materials, such as thin wooden rods or the like.
  • the legs can consist of extruded aluminum tube.
  • “Aluminum tube” also means materials that are not pure aluminum, but also alloys and other equivalent light metals. This feature, which is important for the construction of the invention, can be realized particularly well in such a chair, because extruded aluminum tubes cannot be deformed or cannot be deformed with reasonable effort and, through the choice of the material aluminum or the like, construction principles have to be chosen which are based on the facts of straightness and always take the same cross-section into account. However, if you want to have slim, clear external surfaces that are not interrupted even in the upper end area or flow area near the seat, it makes sense to choose the solution with the frame part with protruding arms that engage between the round bars.
  • a 'frame part' is understood to mean a component which connects the legs, holds together and supports the seat, the support structure of which is not limited to the fact that the "frames" are, as with conventional legs, in the planes determined by the leg axes or close to these planes, but rather that the areas giving stability are formed as upright, flat parts forming a framework.
  • the round bars can be put together from single bars.
  • two round tubes are formed as an integral extruded profile. They can be manufactured well in terms of production technology, offer favorable stability properties with a small cross-section and slim appearance, and allow one without further reinforcement to achieve a certain appearance in terms of the overall design and / or to attach an armrest that matches the style of the chair Insert the third round bar into the recesses of the two round bars attached to the frame part, which are exposed from the attachment and fasten them in a suitable manner.
  • the attractively designed embodiment makes use of this possibility in an advantageous manner for the front legs, whereby according to a further development the Invention the third tube of the front legs can have a pointed outer rib engaging in the recess of the two tubes. On the one hand, this ensures easy, secure installation, and on the other hand, with the help of this interlocking rib-groove construction, stabilization can also be achieved over a longer length, for example by gluing and / or screws.
  • the leg profile tubes have practical narrow and low protective ribs running lengthways on the outside. These are easy to manufacture using the extrusion process and prevent scratching of the surfaces, especially when the chairs are stacked.
  • the construction according to the invention makes it particularly inexpensive to create stackable chairs.
  • the leg tube profiles can expediently have longitudinal centering and fastening ribs on the inside. On the one hand, these serve as reinforcement, but above all they allow the components to be securely aligned with one another because of the necessary bevel cuts and the molded parts to be inserted, the molded parts also being able to grip the fastening ribs.
  • connection ends of the protruding leg connection arms of the frame part and possibly the backrest can each be made at the outer ends of the tubes, possibly with engagement in the tube ends.
  • such solutions only allow very specific designs for the corner connection. It is particularly expedient if the connection is made at a distance below the ends of the leg bars. Suitable connecting elements and / or cover plugs can then be inserted into the ends of the leg bars, which hold together the leg bars which, under the clamping forces of parts to be connected, may be pushed apart.
  • there is an appealing design in the sense of the design which also allows the round bars to be cut off or left in inclined and / or curved surfaces. Appropriate foot and / or end cover and / or connecting plugs are allowed to engage in the pipe ends.
  • the frame part expediently has a rectangular base body with vertical walls, in the corners of which the leg connection arms protrude diagonally.
  • a curved and / or ribbed structure can also be provided for this.
  • leg connection arms for the front legs are expediently allowed to run in a straight line in the diagonal of the chair. So you can combine two inward and one inlaid rod into an attractive slim but sufficiently stable bundle and let the frame part attack geometrically favorably.
  • the frame part can be assembled in one piece or from several elements.
  • a casting solution for the entire part is basically possible for the production in aluminum. However, this requires expensive and large molds.
  • the backrest can be attached in many ways. However, it is useful to have the backrest fastened between the two round bars. In the case of the design with light metal extruded profiles, it is practical to incorporate longitudinal slots from above into which tapered flat parts of the preferably curved backrest engage in the insertion area. The pipe ends are then expediently covered by insertion plugs which hold them together and ensure stability. You can bevel the pipe ends and / or their plugs according to the sloping upper boundary line of the backrest. Then you only need relatively short legs and a connection with short lever arms, but thanks to the inclined design for the most part in the middle of the backrest a favorable support of the back of the user is possible even in higher parts.
  • the chair with extruded aluminum parts is particularly suitable for many applications, especially under hygienic and difficult cleaning conditions.
  • a chair should consist of wood or at least look like it or be designed with wooden outer surfaces.
  • the legs are made of interconnected cylindrical solid wood rods. This configuration allows different connections on the frame part, which can be carried out in conventional connection technology. It is particularly expedient, however, that the ends of the projecting arms of the frame part have dovetail-like thickenings which engage in suitably shaped recesses in two adjacent round rods which are inserted and preferably glued to them.
  • the frame part consists of compression-molded plastic-fiber-wood, to which the outwardly projecting dovetail-like fastening thickenings with a continuous fiber course are molded.
  • connection between the backrest and the rear legs can be formed in a similar manner with integrally formed thickenings and corresponding receiving recesses on the legs.
  • Another particularly expedient and stable connection between the backrest and legs formed from two round wooden rods provides that the backrest has on each side a dovetail-shaped, front-connected metal profile which engages in vertically machined slots in the adjacent wooden round rods. Then you can implement a very slim design and still create a stable connection over a long distance at the highly stressed point, which is also simple and safe from a machining point of view.
  • the third rod of the bundle of the front legs can also be glued to the connection ends of the leg connection arms of the frame part and possibly the other round rods of the leg with recessed, possibly spring-shaped or disc-shaped dowels by means of hidden dowels. This gives you a securely connected front leg made from slender round bars.
  • a frame part made of metal or molded fiber wood is expediently provided, on the leg connection arms of which a vertically extending flat profile in the rear region and in the region of the front legs a T-profile with the middle leg pointing outwards at 45 ° connected, preferably screwed.
  • the leg length and leg thickness of the flat profile and T-profile are considerably smaller than the diameter of the wooden round bars and the wooden round bars are provided with suitable longitudinal slots, by means of which they are attached to the metal legs.
  • the chair concept according to the invention provides a seat which is fastened over the frame part, preferably at a distance.
  • spacers are expediently provided under the seat, in the lower ends of which threaded holes are provided, by means of which the seat with the interposition of spring elements on the frame part is attached. Then you can allow comfortable, sprung sitting, like office chairs, on a chair of a simple design even if you use only a thin or no padding.
  • the spring elements are penetrated by screws, by means of which the spring preload and / or the seat inclination can be adjusted.
  • An easy-to-assemble arrangement provides a U-shaped round wire clamp, which engages through transverse bores in the seat-holding recesses and with washers on both sides of the clamp arms, which are penetrated by the screw installed with the head at the bottom, on which the Centered spring element and the screw then engages in a threaded bore of the seat holding element.
  • a seat made of an unpadded hard, washable material, such as molded wood or metal, even for good seating comfort and to provide passage openings for liquids at its deepest points.
  • the chair with round bar bundle legs can also be optionally and optionally subsequently provided with armrests, which are preferably characterized by the fact that they have a vertical round bar which is inserted into the recess of each rear leg pointing away from the connection on the frame part and fastened to it and wherein the approximately horizontally extending armrest tube is connected to the vertical round bar, preferably with an oblique bend, and merges at its front end into a vertical front end region, which is followed by a horizontal section bent under the seat, which is preferably fastened to the frame part .
  • the first embodiment of a chair according to the invention is shown in FIGS. 1 to 12.
  • the chair 20 has front legs 21.1 and 21.2 and rear legs 21.3 and 21.4, a frame part 22, a seat 23 and a backrest 24.
  • Seat 23 and backrest 24 are formed according to the desired profile from correspondingly editable plywood.
  • the frame part 22 consists of a rectangular frame 25 and protruding leg connection arms 26.1, 26.2, 26.3, 26.4, which together form a unit.
  • Fastening recesses 27, here in the form of cylindrical recesses, for the seat fastening are formed in the inner corners of the frame 25.
  • the manufacture from four frame part elements 22.1, 22.2, 22.3 and 22.4 is selected according to FIGS. 6 and 9.
  • the frame profile parts each have frame arms 28 which are at right angles to one another, the thickened ends 29 of which are provided with connecting slots 30 and chamfered 31 to receive a weld seam 32.
  • tabs 33 with a smooth outer surface fit into the depressions and slots 30.
  • the corresponding legs can, as can be seen and indicated by the axis 34, be riveted.
  • the frame part elements 22.1, 22.2, 22.3 and 22.4 are cut off with the height 44 of extruded profiles correspondingly manufactured as semi-finished products.
  • the front frame part elements 22.1 and 22.2 have straight leg connection arms 26.1 and 26.2 in the diagonals 46, while the leg connection arms for the rear legs 21.3 and 21.4 run up to the connection plane 40 of the rear legs on the diagonals 46, but there are angled to connecting legs 35.
  • the ends 36 of all four leg connection arms 26 are, as shown in FIG. 9, tapered and chamfered at the extreme end, so that weld seams 37 can be accommodated over a large area, but can hardly be seen.
  • the legs 21 consist of bundles of round bars, with two adjacent round bars delimiting an inwardly facing recess 38 and 39 between them.
  • the leg connection arms 26 engage with these tapered ends 36 in these recesses.
  • the legs 21 are formed from extruded aluminum profile tube and welded with the aid of the weld seams 37. This results in a stable frame welded together from light metal extrusions.
  • the height 44 of the frame part 22 with its leg connection arms 26 can be selected in such a way that the strength requirements take into account the desired design.
  • the pure light metal construction offers plenty of freedom for the visual design, whereby a self-supporting, slim frame can always be realized, on and on which seats and backrests of different types can be attached.
  • the legs are formed from bundles of round rods which have favorable stability properties with little material expenditure and a slim, elegant-looking appearance.
  • the rear legs are made up of two round bars
  • the front legs are made up of three round bars.
  • Both the rear legs and the front legs each have a double-tube pair which is produced in one piece using the extrusion process and is designed in the manner of a twin rifle barrel.

This results in an optically appropriately coordinated overall impression of the legs, taking into account the stability conditions.
  • the diameter 48 can be, for example, 24 mm, while the diameter 47 is, for example, 27 mm.
  • the round bars 45 designed as double round tubes have on their inner walls 50 opposite longitudinal ribs 51 projecting inwards, which are arranged in planes running perpendicular to the planes 41 and 42. They serve to reinforce and center plugs to be treated below. Constrictions or depressions 38 and 39 are formed between the two tubular round bars 45.1 and 45.2 or 45.3 and 45.4.
  • the tapered ends 36 of the leg connection arms 26 extend in the corresponding areas to the inner depressions 38.
  • the tubular third round rod 45.5 is inserted into the outer recesses 56 of the front legs.

  • the front legs are designed in a way that not only determines the particularly appealing design, but also is favorable in terms of manufacture and strength, so that their upper limit 62 extends by an amount 63 above the upper edge 64 of the frame part. From there, the two front legs are cut off in planes 65 running obliquely downwards.
  • cover cap plugs 66 are inserted into the upper, obliquely cut ends of the tubes, so that their retaining tongues cling to the inner circumference and, above all, to the centering and retaining ribs 51. This results in a completely smooth, continuous design of the leg, which has no attachment joints for attachment to the frame and which also has no corners and burrs on which items of clothing could get caught.
  • Bottom glider plugs 67 and 68 are inserted into the tube bundle legs in a suitable profile. Mainly in the front legs 21.1 and 21.2, they hold the three tubular rods 45.3 / 45.4 / 45.5 formed from two pieces together.
