Definitions

  • the invention relates to legless seating, in particular for leisure purposes, with a seat which can be placed directly on the floor and which is pivotably arranged on a frame which can be assembled from tubular or rod elements and a support part which can be placed on the floor and at a fixed angle has a backrest part arranged to the support part, the support part and backrest part each being formed from a U-shaped tube or rod element which are connected to one another by plug connections on their free legs via an L-shaped tube or rod element which serves as a connecting element, and the connecting elements are pivotable inwards about the axes of the legs of the support part, the legs of the connecting elements connected to the backrest part being shorter than the distance between the legs of the support part at their ends, and the frame is provided with a cover on which the seat befe in the area of the connecting elements is increasing.
  • Legless seating furniture of this type which could also be referred to as an "armchair” or “earth chair”, has proven particularly useful when sitting in the open, possibly on uneven railings. If you sit in such terrain directly on the floor or on a seat cushion placed on the floor, the difficulty arises that there is no back support, which makes sitting extremely stressful after a while.
  • legless seating offers the possibility to sit well supported on the floor in the back.
  • they have a number of disadvantages, which make sitting as well as assembling and disassembling the seating furniture and / or transport uncomfortable.
  • the known seating furniture mentioned above has a seat that slopes downward in a wedge shape and ends practically shortly before the fastening point on the frame part. If the frame part is now provided with an elastic cover, it bulges backwards when sitting on the seat, and when you slide back you sit in the position of the seat that is least padded or with part of the buttocks directly on the floor .
  • Another disadvantage of the known seating furniture is the fact that, due to the type of attachment between the seat and the frame, the seat cannot be completely folded up against the backrest part. This is unfavorable for the transport of the seating furniture.
  • the seating as described, for example, in US Pat. No. 4,410,214, can be dismantled in that the tube or rod elements which compose the frame can be taken apart. To do this, however, the cover must first be removed, which is uncomfortable on the one hand and on the other hand has the further disadvantage that after disassembly you have a heap of individual parts in front of you, which in some way has to be stowed in a bag or other container. It is particularly inconvenient that the individual tube and rod elements of the frame have very different dimensions, so that they are uncomfortable to pack and in particular the smaller connecting elements can easily be lost.
  • the frame is partly made of tubular elements (support part and backrest part) and partly made of rod elements (connecting elements), which are simply inserted into one another. This creates relatively sharp edges on the frame, which are uncomfortable and can lead to injuries.
  • the object of the invention was to improve legless seating of the type described above and specified in the preamble of claim 1 in such a way that the aforementioned disadvantages are avoided and seating is created on which on the one hand a very comfortable sitting is possible and at on the other hand, the frame can be disassembled without the cover having to be removed, and after disassembly the seating can be folded up, with the parts of the frame remaining in the cover, and in the collapsed state a coherent package of small dimensions is created which is easy to carry is and can be easily stowed away.
  • the lengths of the legs of the support part and the backrest part are dimensioned such that the sum of the length of a leg of the support part and the length of the leg of the connecting element connected thereto is substantially equal to the length of the seat and the length of the legs of the backrest part is less than or equal to the length of the seat, and that the connecting elements as well as the support part and the backrest part consist of tube or rod elements with the same outside diameter, which connect to one another without a gap via pin and hole connections, and the seat so is designed that its thickness is constant over the entire length, and that the pivoting attachment between the seat and the cover of the frame is designed so that it is connected to the seat on the side surfaces or top thereof at a predetermined distance from the rear edge of the seat and with the reference is connected at a point around e a predetermined amount is offset upwards relative to the lower surface of the support part.
  • the joint use of the above-mentioned features creates a piece of seating furniture in which the seat engages under the frame at its rear edge in the opened operating state, which enables particularly comfortable sitting. Nevertheless, due to the special attachment of the seat to the cover of the frame and due to the special dimensioning of the individual parts of the frame, the furniture can be dismantled and folded up quickly and easily, and if a cover material of sufficient elasticity is used, it is easy to disassemble the frame within the cover is possible.
  • a firm, dust-proof, hard-wearing cover material can be used as the material for the cover, for example of a quality as used in the manufacture of house tents. Of course, other materials can also be used which have a certain elasticity.
  • Different materials can also be used as covers on different sides of the seating.
  • a moisture-repellent and rot-proof cover part can be used on the bottom side, while skin-friendly materials are used on the sides facing the body.
  • a suitable foam plastic can be used as the cushioning material.
  • the legless seating furniture shown in the drawings consists of a padded seat 1 which can be placed directly on the floor and which is arranged within a cover 6 which is guided around a frame which can be assembled from tubular elements 2, 3, 4, 5.
  • the frame thus consists of four parts, namely an essentially U-shaped support part 2 resting on the floor, a likewise essentially U-shaped backrest part 3 and two essentially L-shaped support parts 2 with the backrest part 3 connecting connecting elements 4 and 5.
  • Parts 2 and 3 and parts 4 and 5 are identical.
  • the parts 2 to 5 are connected to one another via hole-and-pin connections.
  • support part 2 and backrest part 3 have pins 2.1 and 3.1 on the free ends of their legs, which can be inserted into corresponding holes in the free ends of the legs of the connecting elements 4 and 5.
  • All parts of the frame have the same outer diameter, and the hole-pin connections 2.1 and 3.1 are designed so that the nested frame parts connect to each other without a step. Furthermore, the connection is such that when loosening the hole-pin connection 3.1, the connecting elements 4 and.5 um the hole-pin connection 2.1 can be pivoted inwards.
  • the length of the legs of the connecting elements 4 and 5 connected to the backrest part 3 is dimensioned such that in the pivoted inward state, these legs, as can be seen in FIG. 8, lie within the supporting part 2.
  • the hole-pin connection between the elements of the frame can also be designed such that the pins are on the connecting elements 4, 5 and the corresponding holes on the support part 2 and on the backrest part 3.
  • Support part 2, backrest part 3 and the connecting elements 4, 5 can consist of metal pipes, the pipe bends being able to have the smallest possible radius which still allows cold deformation without reducing the cross-section.
  • the outer surfaces of the parts can be designed to be corrosion-protected in a manner known per se.
  • the free legs of the support part 2 and the backrest part 3 can be oriented such that they do not run parallel to one another but open at a small acute angle. As a result, a better tension of the cover 6 guided around the frame is achieved.
  • the frame consisting of parts 2, 3, 4 and 5 is held together by a cover 6 guided around it.
  • the cover 6 can consist of a textile material that is suitable for the respective place of use of the seating is best suited. It is expediently made from a continuous material web and sewn together so that it encompasses both the frame 2 to 5 and the padded seat 1. This material web can, as shown in FIG. 2, start, for example, on the rear side of the backrest part 3, is then led around the upper edge of the frame to the front of the frame and down this to the surface of the seat 1, runs along this to the front edge of the seat 1 , is guided around this in order to run along the underside of the seat 1 to the rear edge of the seat.
  • the rear end of the seat in a double fold 6.2, the apex of the fold 6.2 being returned to the top of the seat 1, into the region of the web running down the front of the frame and at least on the two side edges of the seat 1, 3 and 4, for example by sewing, is fixed.
  • the web 6 is then guided along the double fold 6.2 along the underside of the support part 2 and runs over the top of the support part 2 back to the rear side of the backrest part 3, where its end collides with the beginning of the web and a slot is provided at this point , which makes it possible to reach into the interior of the cover to disassemble or plug the frame parts together.
  • the side edges of the web are joined by seams 7 where they lie opposite one another on the sides of the frame and the seat according to the guide described above. This is easy to do with the described guidance of the train. Only a few markings need to be made on the fabric. Then it is possible to completely cover the cover ------------ sew without the need for complicated cutting work.
  • the cover is sewn so that it fits tightly and without folds on the frame and the seat cushion 1.
  • the material should have such elasticity, and so much room is left in the longitudinal direction that the backrest part 3 can be pulled up from the two connecting elements 4 and 5 even when the cover is tensioned within the cover.
  • the seat 1 which can consist, for example, of a piece of a suitable foam plastic arranged within the cover 6, is designed and arranged such that its thickness is constant over the entire length. At least in the area of the rear edge of the seat, its width can be somewhat smaller than the distance between the free legs of the support part 2 at this point. In this way, the seat 1 can be guided at its rear edge either under or between the parts 2, 4 and 5 of the frame, measured with about 1/10 of its length from the rear edge. This has the great advantage that when sitting on the seating furniture, with the cover being arched somewhat backwards when leaning against the backrest part, the seat of the seated person rests entirely on the seat 1, which enables an extraordinarily comfortable seat.
  • the seat 1 is pivotally connected to the frame 2 to 5 via the cover 6.
  • the swivel attachment takes place via a flexible bridge 6.1, which is formed by the cover 6 at this point, namely by the opposite web sections, on the front of the frame or the top of the seat 1 and the double fold 6.2 on the underside.
  • the longitudinal dimension of this bridge is approximately 55% of the thickness of the seat.
  • the flexible bridge 6.1 is arranged and designed such that the sum of the length of the bridge 6.1 and the height of its attachment point on the cover 6 of the frame is smaller than the distance d of the attachment point of the bridge 6.1 on the seat 1 from the rear edge of the seat. In this way it is achieved that, as shown in FIG. 4 not immediately apparent, after swiveling up the seat when the seat rests against the front of the frame, the rear edge of the seat sits on the floor and the weight of the entire frame over the bridge 6.1 and supports the seat 1 and the rear edge of the seat on the floor. In this state, the frame therefore only rests on the floor with the outer end on the left in FIG. 2 and is supported on the right via the seat 1.
  • the seat 1 is pushed upwards by the acting forces and the inclined position of the backrest part creates a force component which presses the seat 1 against the front of the frame 3, 4, 5. This has the consequence that the seat 1 assumes a very stable position in the folded-up position and does not easily fall down again by itself, for example due to wind.
  • the seating can be easily disassembled and folded for transportation, creating a package that corresponds in its dimensions in length and width to the size of the seat 1.
  • the individual parts of the frame have special dimensions.
  • the free legs of the support part 2 and the backrest part 3 have the same length 12 or 13, which corresponds to approximately 2/3 of the length 11 of the seat 1.
  • the legs of the connecting elements 4 and 5 connected to the supporting part 2 are dimensioned such that the sum of the length 12 of one leg of the supporting part 2 and the length 14 of the leg of the connecting element 4 and 5 connected thereto is substantially equal to the length 11 of the Seat is.
  • the repositioning is done in reverse order. First the seat 1 is folded forward, then the backrest part 3 with the cover attached is lifted up, by engaging in the slot 6.4 (FIG. 2) of the cover, the connecting elements 4 and 5 are erected and the backrest part 3 is inserted into them.
