Abstract

A method for providing a dismantling groove in an element for a product to be assembled by a plurality of elements locked by a locking arrangement including a flexible tongue is disclosed. The method includes providing an insertion groove and a dismantling groove in the same element. The dismantling groove extends along the element between a first side and a second side and is configured for receiving the flexible tongue of the locking arrangement for locking the element to another element having a tongue groove. The dismantling groove is provided in the element such that it extends from the first side to the insertion groove and along a portion of the insertion groove, and is configured to receive a dismantling tool for dismantling the element from the other element. An element with an insertion groove and a dismantling groove is also disclosed.

First claim

The invention claimed is:

1. Method for providing a dismantling groove in a first element for a product to be assembled so as to include a plurality of elements that are locked by a locking arrangement including a flexible tongue, the method comprising:
providing the first element, which has a first side and an opposing second side;
providing an insertion groove in the first element, which insertion groove extends along the first element between the first side and the second side and is configured for receiving the flexible tongue of the locking arrangement for locking the first element to a second element having a tongue groove; and
providing a dismantling groove in the first element, which dismantling groove extends from the first side to the insertion groove and along a portion of the insertion groove, and is configured to receive a dismantling tool for dismantling the first element from the second element;
the providing of the insertion groove and the providing of the dismantling groove comprising milling with a single milling tool having a first cutting surface for milling the insertion groove and having a second cutting surface for milling the dismantling groove, wherein the milling of the insertion groove is carried out with the milling tool in a first position with respect to a radial direction that is radial relative to a longitudinal axis of the milling tool, and wherein the milling of the dismantling groove is carried out by moving the milling tool to a second position spaced in the radial direction from the first position.

2. The method according to claim 1 , comprising providing the insertion groove with at least a first depth into the first element along the entire insertion groove, and providing the insertion groove with a second depth into the first element at the location of the dismantling groove and such that the second depth is deeper than the first depth.

3. The method according to claim 1 , wherein providing the dismantling groove comprises providing a guide surface extending from the first side towards the second side and having at least a portion that is angled less than 90 degrees relative the first side.

4. The method according to claim 1 , comprising controlling the single milling tool to mill the insertion groove and the dismantling groove in a continuous milling action.

5. The method according to claim 1 , wherein the first side comprises an edge section groove and the second element comprises an edge section, wherein the edge section is configured to cooperate with the edge section groove for locking the second element and the first element together.

6. The method according claim 5 , wherein the edge section groove is contiguous with the insertion groove.

7. The method according claim 5 , wherein the edge section comprises the tongue groove, wherein the flexible tongue is configured to cooperate with the tongue groove for locking the second element and the first element together.
