Abstract

The present invention concerns a lamp ( 1 ) having a number of plates ( 3, 4, 5 ). The plates ( 3, 4, 5 ) are moveable between a position where the plates ( 3, 4, 5 ) form a common outer surface and a position where the plates ( 3, 4, 5 ) are separated from each other. By means of the plates the shape and appearance of the lamp ( 1 ) may be amended between having the form of for instance a closed sphere and a more or less open form. The plates ( 3, 4, 5 ) are placed on upper and lower curved arms ( 17, 26 ). The curved arms ( 17, 26 ) are connected to an upper ring ( 10 ) and a lower ring ( 9 ). The curved arms ( 17, 26 ) are moved by movement of the lower ring ( 9 ) towards and away from the upper ring ( 10 ).

First claim

1 . A lamp having a number of plates, which plates form a lamp shade, wherein the plates are moveable between different positions by the plates being placed on upper or lower arms of link mechanisms, that each arm receives at least one plate that one end of each arm is connected to an upper ring, that one end of each lower arm is connected to a lower ring, and that the upper ring and lower ring are arranged moveable towards and away from each other.

2 . The lamp of claim 1 , wherein the plates are moveable between a closed position, where the plates form a common outer surface, and an open position, where the plates are separated from each other.

3 . The lamp of claim 1 , wherein the upper and lower arms are upper curved arms and lower curved arms, respectively, and wherein each plate is received at an end of one of the upper curved arms or the lower curved arms.

4 . The lamp of claim 3 , wherein the end of each upper curved upper arm opposite the end receiving the plates is received in the upper ring by means of a pivot and wherein the end of each curved lower arm opposite the end receiving the plates is received in the lower ring by means of a pivot.

5 . The lamp of claim 4 , wherein each curved upper arm has a lower curved part receiving a lower plate and an upper claw-like part receiving a middle plate, wherein each curved lower arm has an upper curved part receiving an upper plate and a lower claw-like part receiving a middle plate and wherein two adjacent upper curved arm and lower curved arm are connected to each other by means of a pivot at the end of the claw like part of respective upper curved arm and lower curved arm.

6 . The lamp of claim 5 , wherein the upper curved arms and lower curved arms are identical, but placed in opposite directions.

7 . The lamp of claim 5 , wherein each plate is rigidly fixed to respective upper curved arm or lower curved arm.

8 . The lamp of claim 4 , wherein the lower ring is received moveable on a rod in a direction towards and away from the upper ring, and wherein the rod is arranged hanging down from an intermediate band, which intermediate band is arranged hanging down from the upper ring.

9 . The lamp of claim 8 , wherein a first string part is received in a fixation on the upper side of the lower ring, which first string part goes from the lower ring around a wheel placed at the lower end of the intermediate band and down on the opposite side of the wheel and wherein a second string part hangs down from the lower ring fixed to the lower ring.

10 . The lamp of claim 5 , wherein the all the middle plates have the same form and wherein all the upper plates and all the lower plates have the same form and wherein the upper plates and the lower plates are placed in inverted directions.

11 . The lamp of claim 9 , wherein it has a locking means holding the plates in a desired position.

12 . The lamp of claim 11 , wherein the locking means comprises a slide having an opening for receiving one of the string parts and which locking means further comprising a spring urging the slide in a direction pressing the string part against one side of the opening of the slide.

13 . The lamp of any claim 1 , wherein it is a ceiling lamp.
