  11. 11 . A locking device (40) for a joinery product, the locking device comprising: a compressible locking pin (42), and a rotatable plug element (48) having at least one engagement means (61) comprises at least one support means (69) and an opening (66) arranged in a 90° angle in relation to the at least one support means (69), wherein in a first rotation state of the plug element (48), the locking pin (42) is positioned in a first position, and in a second rotation state of the plug element (48), the locking pin (42) is positioned in a second position, different from the first position, wherein the opening (66) is configured to receive a portion of the locking pin (42) in the first rotation state of the plug element (48).
  12. 12. A locking device (40) for a joinery product, the locking device comprising: a compressible locking pin (42), and a rotatable plug element (48) comprising an indentation (71), wherein in a first rotation state of the plug element (48), the locking pin (42) is positioned in a first position, and in a second rotation state of the plug element (48), the locking pin (42) is positioned in a second position, different from the first position, wherein the indentation (71) is configured to receive a portion of the locking pin (42) in the first rotation state of the plug element (48).

Description

A LOCKI NG DEVICE FOR A JOI N ERY PRODUCT TECH N ICAL FI ELD The present invention relates to a locking device for a joinery product, a joinery product, and a method for producing a joinery product. BACKG ROU N D A furniture product provided with a mechanical locking element is known in the art, e.g., by WO2015/038059. The furniture product comprises a first panel connected to a second panel by a mechanical locking element comprising a rod-shaped element, an insertion groove, a locking groove, and a locking element. There is a need for a locking device for a joinery product of joinery elements with an improved locking. SU M MARY It is an object of at least embodiments of the present disclosure to provide an improvement over the above described techniques and known art. Another object of at least embodiments of the present disclosure is to provide a locking device which facilitates the production of a joinery product, and which facilitates dismantling of the joinery product. In a first aspect, a locking device for a joinery product is provided, the locking device comprising a locking pin, and a rotatable plug element. The plug element has at least one engagement means configured to interact with the locking pin such that in a first rotation state of the plug element, the locking pin is positionable in a first position, and in a second rotation state of the plug element, the locking pin is positionable in a second position, different from the first position. This locking device is advantageous in that the two rotational states of the plug element provide a possibility to arrange the locking pin in two different positions. One of the positions may be a locked position and the other of the positions may be an unlocked position. The locking pin may be positioned in both a locked position and an unlocked position without the need of removing the plug element. This is advantageous in that the plug element is less likely to be lost during maneuvering of the locking device and of the joinery product. In one embodiment, the locking pin is unsupported by the engagement means in the first position, and supported by the engagement means in the second position. In one embodiment, the engagement means comprises at least one support means configured to support the locking pin in the second position. In one embodiment, the at least one support means is arranged such that the at least one support means abut an end portion of the locking pin such that the locking pin is supported by the at least one support means in the second position. In one aspect, a locking device for a joinery product is provided. The locking device comprises a compressible locking pin comprising a flange, and a rotatable plug element. The plug element has at least one engagement means comprising two curved arms. In a first rotation state of the plug element, the locking pin is positioned in a first position, and in a second rotation state of the plug element, the locking pin is positioned in a second position, different from the first position. The first position is an unlocked position, and the second position is a locked position of the locking device. Upon rotation of the plug element from the second rotation state to the first rotation state, the curved arms are configured, by interaction with said flange, to pull the locking pin from the locked position to the unlocked position. In one embodiment, the compressible locking pin is de-compressible to an initial state after having been compressed. In one embodiment, in the first rotation state of the plug element, the at least one support means is located in a non-supportive position in relation to the locking pin, and, in the second rotation state of the plug element, the at least one support means is rotated approximately +/- 90° compared to the orientation of the at least one support means in the first rotation state of the plug element. In one embodiment, the locking pin comprises a flange, and the engagement means further comprises guide means configured to interact with said flange. In one embodiment, the guide means comprises two curved arms configured to interact with the flange of the locking pin, and configured, upon rotation of the plug element from the first rotation state to the second rotation state, to push the locking pin from the first position to the second position. This configuration is advantageous in that the locking pin is maneuverable via the guide means. In one embodiment, upon rotation of the plug element from the second rotation state to the first rotation state, the guide means are configured to pull the locking pin from the second position to the first position. The guide means are advantageous in that the locking pin may be put in both the first rotation state and the second rotation state by interaction with the guide means. In one embodiment, the plug element comprises an opening arranged in a 90° angle in relation to the at least one support means, and wherein the
