Definitions

  • the invention relates to the field of the furniture industry. It affects one Device and method for attaching a hollow backrest for Seating.
  • the invention attempts to overcome the disadvantages of the prior art described avoid. It is based on the task of a simple device and a easily executable method for attaching a formed from a blow molded part to create hollow backrest for seating, which face each other the known prior art through a reduced expenditure of time and money as well as an improved quality of attachment, the Attachment should be almost invisible.
  • the advantages of the invention are that they are comparatively simple
  • the backrest is attached to the frame, but it is very stable.
  • the Bearing bracket absorbs the leaning forces on the one hand and serves together on the other with the terminal block for fastening the backrest.
  • terminal strip and the frame in the middle each Opening for receiving a connector, preferably a screw or have a blind rivet. In this way, a very good frictional Connection between the hollow backrest and the frame of the Manufacture seating furniture.
  • the bearing bracket is at least partially included is encased in a damping element.
  • the damping element is there made of a compensating material and advantageously causes a Noise is avoided and a soft stop to the rear is ensured becomes.
  • the method according to the invention for fastening the device is thereby characterized in that the hollow backrest with its lower, partially open Side is partially pushed over the bracket, then the Terminal strip is inserted into the lower side of the backrest so that when then completely push the hollow backrest over the bearing bracket the openings in the frame and in the terminal strip are almost congruent come to lie on each other and then through the openings Connecting part is pushed and fastened.
  • the single figure shows a perspective view of part of a chair frame with the hollow backrest to be attached and the necessary Additional parts. They are only the elements essential for understanding the invention shown.
  • the single figure shows a perspective view of part of a metallic Tubular frame 1 for a chair with one to be attached to this frame 1 hollow backrest 2 and the necessary additional parts.
  • the assembly the individual parts are indicated by dashed arrows in the figure.
  • the backrest 2 is made of plastic and is manufactured as a blow molded part. Out the figure does not show that the lower narrow side 7 of the backrest is predominantly open and only from the front and the rear Side of the backrest 2 each has a narrow edge bent to the side 7. The other sides of the blow molded part 2 are closed.
  • the shape of the bottom Page 7 of the backrest 2 is adapted to the shape of the frame 1, so that at one Attachment of the backrest to the frame is given a positive fit.
  • the frame 1 is in the area in which the backrest 2 is attached should, a u-shaped bracket 3 made of metal attached.
  • a u-shaped bracket 3 made of metal attached.
  • the crossbar connecting the legs the bracket 3 protrudes upwards.
  • Bearing bracket 3 around a damping element 4, which is made of a compensating material exists, attached.
  • the bracket 3 serves to absorb the leaning forces.
  • the damping element 4 causes noise when leaning avoided and a soft stop to the rear ensured.
  • a terminal block 5 is also shown.
  • the terminal block 5 is a curved gutter-like piece of sheet metal, the curvature of which has an inner radius, which corresponds approximately to the outer radius of the tubular frame 1.
  • a bore 8 which has an internal thread.
  • the openings 8 and 9 serve the inclusion of a connector 6.
  • the connector 6 is in present embodiment a screw. But it could be instead of Screw z. B. a blind rivet can also be used.
  • the described device according to the invention is assembled as follows:
  • the hollow backrest 2 is first with its lower, partial open side 7 partially pushed over the bracket 3, so that the Damping element 4 is located inside the hollow backrest 2.
  • the Terminal strip 5 inserted into the lower side 7 of the backrest 2 and turned so that on the one hand its curved surface points upwards and on the other hand the Terminal strip 5 rests on the inside edges of page 7.
  • the terminal block 5 is shifted and adjusted so that the next complete Push the back 2 over the bracket 3, the opening 9 in the tubular frame 1 and the opening 8 with the threaded hole in the terminal block 5 approximately come to lie congruently on one another.
  • the invention is not based on the described embodiment limited. So the required adhesion between frame 1, Terminal strip 3 and backrest 2 also by inserting a blind rivet instead of a screw connection.
  • an unpadded backrest is of course also the invention Attachment of a padded hollow backrest suitable. With these two The only variant is the space between the blow molded parts and the Different sizes of frames. This is compensated for by the terminal strip.
