Building panels provided with a mechanical locking system
US 9194134 B2
1. Floorboards including at least a first floorboard and a second floorboard provided with a mechanical locking system comprising:
wherein said inner element and said outer element vertically overlap each other in the first position.
2. Floorboards as claimed in claim 1, wherein the inner element in the first position is arranged above or below the outer element.
3. Floorboards as claimed in claim 1, wherein the inner element in the first position is arranged partly above and partly behind the outer element, or is arranged partly below the outer element and partly behind the outer element.
4. Floorboards as claimed in claim 1, wherein the outer element is provided with a guiding groove at either an inner and upper edge of the outer element or at an inner and lower edge of the outer element, and at least a part of the inner element in the first position is arranged in said guiding groove.
5. Floorboards as claimed in claim 1, wherein the outer element is provided with a guiding groove at an inner surface of the outer element, between an upper surface and a lower surface of the outer element, and at least a part of the inner element is arranged in said guiding groove in the first position.
6. Floorboards as claimed in claim 4, wherein the guiding groove extends essentially along the whole longitudinal length of the outer element.
7. Floorboards as claimed in claim 4, wherein the inner element comprises a first protruding part configured to cooperate with the guiding groove, to obtain said displacement of the outer element.
8. Floorboards as claimed in claim 7, wherein the first protruding part in the first position is arranged outside of the outer element.
9. Floorboards as claimed in claim 6, wherein the first protruding part is one of wedge shaped and essentially spherical shaped.
10. Floorboards as claimed in claim 1, wherein a cross section of the inner element is one of an L-shape, rectangular shape, and an essentially circular shape.
11. Floorboards as claimed in claim 1, wherein the entire outer element is arranged within the displacement groove in the first position.
12. Floorboards as claimed in claim 1, wherein the floorboards comprise a wood-based core made of at least one of MDF, HDF, OSB, WPC (Wood Powder Composite), and particleboard.
13. Floorboards as claimed in claim 1, wherein the floorboards comprise a plastic core.
14. Floorboards as claimed in claim 7, wherein the first protruding part in the first position is arranged at least partly in a recess of the outer element.
15. Floorboards as claimed in claim 14, wherein the first protruding part is one of wedge shaped and essentially spherical shaped.
16. Floorboards as claimed in claim 1, wherein the outer element includes two opposed long edges, and a first short edge and second short edge which oppose each other, and the outer element has a uniform cross-section from the first short edge to the second short edge.
17. Floorboards as claimed in claim 1, wherein the inner element includes two opposed long edges, a first short edge and second short edge which oppose each other, and a protruding part at the first short edge, wherein the inner element has a uniform cross-section with the exception of the protruding part at the first short edge.
18. Floorboards as claimed in claim 1, wherein the outer element has a rectangular shape in plan view as seen from above the floorboards.
19. Floorboards as claimed in claim 1, wherein the outer element has a substantial rectangular shape in plan view as seen from above the floorboards, and two corners of the substantial rectangular shape which face the inner element each have a chamfer.
This application claims the benefit of Provisional Application No. 61/774,749 filed on Mar. 8, 2013. The disclosure of Provisional Application No. 61/774,749 is hereby incorporated by reference herein in its entirety.
FIGS. 17-19 show a method for producing an inner element of a tongue, according to embodiments of the present disclosure.
FIG. 20 shows an embodiment of an inner element of a tongue, according to an embodiment of the present disclosure.
FIGS. 21 and 22 show a tongue with an inner element having a circular cross-section, according to an embodiment of the present disclosure.
FIGS. 23-25 show a displacement groove provided with recess, according to an embodiment of the present disclosure.
FIG. 26 shows a tongue from a top view, according to an embodiment of the present disclosure.
A method for producing the first protruding part 36 and/or the second protruding part 40 of the inner element 31 is illustrated in FIGS. 17-19. A plastic blank 50 of an elongated shape is displaced into a press tool comprising a first part 55 and a second part 56. The first part 55 and the second part 56 are displaced against each other and a protruding part 35 at a first short edge of the plastic blank 50 is formed under heat and pressure. The process may be repeated for a second short edge of the plastic blank 50. The method may also comprise the step of forming the second protruding part 35 simultaneously and essentially in the same manner as the first protruding part 35. The produced first and/or second protruding part 35 may be of, for example, an essentially spherical shape or wedge shaped. FIG. 20 shows an inner element 31 that may be produced according to the method illustrated in FIGS. 17-19. The inner element 31 preferably has an essentially circular cross-section and preferably comprises protruding parts 35 of an essentially spherical shape.
FIGS. 21 and 22 show that an inner element 31 with a circular cross section may be combined with a displacement groove 32 having an inner surface 62, which is smaller than the opening of the displacement groove 32. The inner surface 62 may be provided with a round shaped bottom that facilitates the displacement of the inner element 31.
An upper or lower surface of the displacement groove 32 may be provided with a recess 34 having an angled surface at an angle β3 to the horizontal plane. The angle β3 may be in the range of about 3° to about 10°. An embodiment of the recess 34 is shown in FIGS. 23-25. The recess 34 and the angled surface has the effect that the outer element 30 of the tongue 10 tilts and the outer element 30 is restrained from being displaced back into the displacement groove 32 after the outer element 30 is pushed into the tongue groove 33 by the inner element 31. Such a recess 34 may be provided in locking systems comprising any type of the disclosed displaceable tongue.
A preferred embodiment of the tongue 10 is shown in FIG. 26. The inner element 31 and the outer element 30 are produced in one piece by injection moulding of plastic. The inner element 31 and the outer element 30 are connected together by a connection 47 configured to break when the inner element is displaced or when the tongue is inserted into the displacement groove.
