Abstract

A set of mutually lockable panels comprises a first panel having an edge including a male part and a second panel having an edge including a female part for receiving the male part of the first panel in unlocked condition of the panels. The male part has an outer side which, in locked condition of the panels, is directed to the second panel in a direction substantially parallel to the front face of the first panel, and an opposite inner side which is provided with a locking surface. The female part comprises a locking member, which is pivotable about a pivot axis that extends substantially parallel to the edge of the second panel and an actuator for rotating the locking member from its unlocked condition to a locked condition of the panels.

First claim

The invention claimed is:

1. A set of mutually lockable panels, comprising:
a first panel having a front face, a back face and an edge including a male part which is directed in a direction from its front face to its back face,
a second panel having a front face, a back face and an edge including a female part configured to receive the male part of the first panel in unlocked condition of the panels,
wherein the male part has an outer side which, in locked condition of the panels, is directed to the second panel in a direction substantially parallel to the front face of the first panel, and an opposite inner side which is provided with a locking surface,
wherein the female part comprises a locking member and a bendable portion configured to move the locking member with respect to the rest of the second panel by bending the bendable portion, wherein the locking member has a stop surface, which cooperates with the locking surface of the male part in locked condition of the panels so as to lock the panels with respect to each other at least in a direction substantially perpendicular to the locking surface and the stop surface,
wherein the second panel is provided with an actuator configured to displace the locking member from its first position in unlocked and not interengaged condition of the panels to a second position in locked condition of the panels in which the locking surface and the stop surface cooperate,
wherein during a locking action an orientation of the stop surface of the female part is changed from the first position in unlocked and not interengaged condition to the second position, and
wherein the bendable portion is bendable with respect to a bending axis that extends substantially parallel to the edge of the second panel, and wherein the locking member and the bendable portion are formed integral with the second panel.

2. The set of panels according to claim 1 , wherein, in the locked condition of the panels, the locking surface is directed to the front face of the first panel and the stop surface is directed to a back surface of the second panel so as to lock the panels with respect to each other at least in a direction substantially perpendicular to their front faces.

3. The set of panels according to claim 1 , wherein the actuator has a control surface which is directed away from the back face of the second panel and which is displaceable with respect to the back face of the second panel in a direction from its back face to its front face so as to move the locking member.

4. The set of panels according to claim 3 , wherein the actuator is located at the locking member.

5. The set of panels according to claim 4 , wherein the back face of the second panel has a contact surface configured to support the second panel on a basis, wherein the control surface projects from the contact surface in unlocked condition of the panels.

6. The set of panels according to claim 4 , wherein the actuator is a protrusion formed from a cured liquid.

7. The set of panels according to according to claim 3 , wherein the locking member has a holding element configured to hold the locking member in a fixed position with respect to the panels in locked condition thereof, which holding element is remote from the control surface of the actuator.

8. The set of panels according to claim 7 , wherein the holding element and the first panel comprise a snap fastener for snapping them to each other.

9. The set of panels according to claim 4 , wherein the male part has a lower surface directed in a direction from the front face to the back face of the first panel and the female part has a bottom surface directed in a direction from the back face to the front face of the second panel, wherein the lower surface contacts the bottom surface in an interengaged but still unlocked condition of the panels.

10. The set of panels according to claim 9 , wherein the lower surface and the bottom surface also contact each other in locked condition of the panels.

11. The set of panels according to claim 1 , wherein in the locked condition the stop surface is inclined with respect to the front face of the second panel in a direction from its back face to its front face as seen in a direction from the first panel to the second panel.

12. The set of panels according to claim 1 , wherein the outer side of the male part and an edge portion of the second panel which is opposite thereto in locked condition of the panels are provided with a snap fastener for mutually locking them in a direction substantially perpendicular to the front faces of the panels.

13. The set of panels according to claim 1 , wherein the locking member is dimensioned such that in locked condition a free end of the locking member remote from the actuator and directed in a direction from the back face to the front face of the second panel is free from the first panel.

14. The set of panels according to claim 1 , wherein the male part comprises a longitudinal tongue extending along the edge of the first panel and the female part comprises a cooperating groove extending along the edge of the second panel, wherein at least a part of the locking member forms a side wall of the groove.

15. The set of panels according to claim 1 , wherein the locking surface is part of a recess in the inner side of the male part.

16. The set of panels according to claim 1 , wherein the male part and the female part are dimensioned such that in locked condition of the panels the locking member presses the outer side of the male part against the second panel.

17. The set of panels according to claim 1 , wherein each of the panels has a first edge including the male part and an opposite second edge including the female part.

18. The set of panels according to claim 17 , wherein the panels are rectangular and two remaining opposite edges of each panel have a tongue and a groove, respectively, which are configured to couple similar panels along said edges by means of angling in, or wherein two remaining opposite edges of each panel include the male part and the female part, as well, such that the panels can be joined by means of a displacement substantially perpendicular to the front faces of the panels.

19. The set of panels according to claim 1 , wherein the male part and/or the female part is/are partly or entirely made of a different material than the remainder of the panel or panels.

20. The set of panels according to claim 1 , wherein the orientation of the stop surface of the female part is changed between the first position and the second position of the locking member by moving the locking member by bending the bendable portion.

21. A set of mutually lockable panels, comprising
a first panel having a front face, a back face and an edge including a male part which is directed in a direction from its front face to its back face,
a second panel having a front face, a back face and an edge including a female part configured to receive the male part of the first panel in unlocked condition of the panels,
wherein the male part has an outer side which, in locked condition of the panels, is directed to the second panel in a direction substantially parallel to the front face of the first panel, and an opposite inner side which is provided with a locking surface,
wherein the female part comprises a locking member, which is pivotable about a pivot axis that extends substantially parallel to the edge of the second panel, wherein the locking member has a stop surface remote from the pivot axis, or wher
