Definitions

  • the above invention relates to a seat device which can be used both as an armchair and as a chair or vice versa.
  • chairs and armchairs have numerous construction elements in common. It was also found that numerous components also have the same dimensions. The inventor has recognized that, however, these common components must be arranged in different positions in order to enable differentiated use of the seat device. It is true that both an armchair and a chair are designed to accommodate the same being, the human body.
  • both an armchair and a chair with a very different position of the common components are used, because of the different position and arrangement of the body of the user of a chair or an armchair. If the seating device is used as a chair, it is known that the position of the human body more upright and aligned more vertically, the backrest is almost vertical and the distance from the seat to the floor is much larger. In general, armrests can be dispensed with.
  • the seat device is used as an armchair, the position of the human body is significantly more inclined and the backrest also has a position with a greater inclination, furthermore the seat surface of an armchair has a smaller distance from the floor and the seat surface and the backrest of a armchair are usually also assigned laterally arranged armrests.
  • a seat device which is provided with an adjustable backrest in its inclination.
  • the chair-like seat device which lacks side armrests when used as an armchair, can be converted from a chair into a cart-like transport device. A conversion into an armchair with armrests is not possible with this embodiment.
  • a new seat device is proposed that frame-like side parts are arranged on both sides of the base frame about pivot axes inclined with respect to the horizontal plane, that the frame-like side parts have an angled half-surface on their upper side to form a seat surface and, after pivoting by approximately 180 °, form armrests arranged laterally for the chair surface molded onto the base frame.
  • the seat device which is identified overall by 1, consists of a frame which is indicated overall by 2.
  • the frame is e.g. made of bent steel tube. Of course, other materials can also be used.
  • the frame 2 has a cross strut 3, the axis (X) of which is inclined with respect to the horizontal bottom 4.
  • a backrest 5 protrudes from the top of the frame 2, which advantageously has a slightly angled shape.
  • two side frames are connected, which are also made of bent tube and are identified overall by 7.
  • the side frames 7 form a horizontal surface 8 on their upper side.
  • the side parts 7 essentially have a C-shaped shape and a support 8a is formed on their underside.
  • the section of the frame, which is identified as strut 3 has on its left and right sides projecting arms 9 and 10, which form a small, self-contained frame which serves as a support frame, depending on the position which is occupied by the seat device 1 .
  • the side frames 7 are arranged such that their upper, horizontally arranged surfaces 8, facing each other.
  • a seat surface S is thus formed, which allows the seat device 1 to be used as a normal chair.
  • the seat device 1 is not to be used as a chair (FIG. 1) but as an armchair (FIG. 3), it suffices to move the side frames 7 around the hinges 6 with an inclined axis (X), as shown in FIG. 2. to pivot, whereby the side frame 7 perform a pivoting movement in the direction of arrow (f).
  • the frame parts 3, 5, 9, 10 are pivoted about an imaginary axis (1) arranged horizontally.
  • the horizontally arranged axis (1) does not necessarily have to be provided in the position shown in the drawing; the imaginary axis is only shown in order to better explain the pivoting movement of the backrest 5 and the base frame 9, 10 in the direction of the arrow (g) (FIG. 2).
  • This enables the section 9 or 10 of the frame to serve as a support, whereas the more inclined backrest 5 together with the upper surface of the frame 10 forms the seat surface (S ') of the armchair, as shown in FIG. 3 is.
  • the armchair After the pivotal movement of the side frames 7 around the hinges 6, the armchair also has armrests which are formed by the horizontal partial surfaces 8 which delimit the side frames 7 at the top.
  • the entire frame of the seat device 1 is covered with fabric or other suitable material.
  • the cladding material was not shown in the drawings. The cladding is required to form the backrest 5, as well as the horizontal surfaces 8 for the seat surface (S) or the armrests, and the seat surface S ', when the seat device 1 is used as an armchair.
  • the seat device 1 shows the seat device 1 in a front view, specifically in the direction of view according to arrow IV in FIG. 1.
  • the seat device 1 has side frames 7 which are arranged in such a way that the horizontal surfaces 8 are facing each other so as to form, together with the backrest 5, which is arranged almost vertically, a chair, the seat surface S of which is formed by the horizontally arranged and joined partial surfaces 8.
  • the seat surface S is at a greater distance from the floor 4 than when the seat device 1 is used as an armchair.
  • FIG. 5 shows the seat device 1 in a front view, in the viewing direction according to arrow 5 in FIG. 2. From this illustration it is easier to see how the pivoting movement of the side frames 7 and the associated surfaces 8 takes place about the hinges 6 which have inclined pivot axes.
  • Fig. 6 shows, always in front view and in the direction of view, according to arrow 6 of Fig. 3, the seat device 1 at the end of the pivoting movement of the side frame 7 and the horizontally arranged surfaces 8, in such a way that after further pivoting about the horizontal axis (1) the seat device 1 is available as an armchair, the upper section of the frame 10 being used as the seat surface S 'and the horizontally arranged surfaces 8, which are now directed outwards, as armrests.
  • the embodiment shown here has a backrest 5, with which the lower part (always using pivot hinges 6 with an inclined pivot axis (X)) are connected to side frames 7 which are pivotable about the axis X.
  • the side frames 7 have horizontally arranged partial surfaces at their upper end.
  • the side parts have, for example, the shape of an open C-shaped body and serve as a base frame or support frame, both for the chair and for the armchair.
  • this component S ' is connected to the backrest 5 by arranging the component S' parallel to the backrest 5, as shown in FIG. 7.
  • Fig. 8 the seat device 1 is shown in side view, the pivoting of the side frame with the associated horizontal sub-planes 8 around the hinge 6 is shown in the direction of arrow (f).
  • FIG. 9 shows a side view of the seat device 1 after it has been converted into an armchair.
  • the backrest 5 is more inclined, the component S 'is arranged almost in a horizontal position and, using small pins 12, there is a firm connection with openings 13, which are incorporated in anchoring plates 14 and which are firmly connected to the side frames 7 are.
  • the horizontal partial surfaces 8 are directed outwards in this position in order to form armrests.
  • the seat device according to FIGS. 10, 11 and 12 likewise has lateral frames or components 7 which can be pivoted about suitable hinges 6 which are connected to the lower part of the backrest 5.
  • the seat surface S is articulated using suitable bearings and / or swivel hinges 20 assembled.
  • the brackets and hinges are attached to the front or back of the side frame 7 of the seat device 1.
  • the seat S can be pivoted about a pivot axis (Z).
  • the pivot axis is arranged parallel to the front of the seat device.
  • the same result, as shown in Fig. 11 with dashed lines, is achieved when the seat (S) is pivotable about an axis (Q).
  • the pivot axis (Q) is arranged parallel to a side frame 7 of the seat device 1.
  • the seat surface (in front view considered) shape of a flat bowl.
