PANEL
First Claim
1. A panel comprising a body with at least one plastic layer, complementary locking means provided in pairs at mutually opposite panel edges, at least one pair of locking means with hook profiles, namely a receiving hook and in opposite relationship thereto an arresting hook, with the proviso that the receiving hook has remote from the body a hook edge and arranged nearer to the body a receiving recess, wherein the receiving recess is open towards the top side, the arresting hook is provided with an arresting recess arranged nearer to the body and open to the underside and has an arresting step which is arranged remote from the body and which fits in a vertical joining direction into the receiving recess of the receiving hook, the arresting hook has a joining surface remote from the body and also remote from the body a vertically acting arresting contour, the receiving hook has a joining surface nearer to the body and also nearer to the body a positively locking contour which fits together in positively locking relationship with the arresting contour, that is remote from the body, of the arresting hook so that vertical locking can be implemented, the arresting hook has arranged nearer to the body a horizontal locking surface at its arresting step, the receiving hook arranged remote from the body has a horizontal locking surface in the receiving recess, formed at the receiving hook is a narrowed receiving opening through which the arresting step can be inserted substantially in the vertical joining direction into the receiving recess, and the free step end of the arresting step is narrower than the width of the receiving opening of the receiving hook, characterised in that the arresting contour, that is remote from the body, of the arresting hook is set back behind the plane of the joining surface of the arresting hook, the positively locking contour, that is nearer to the body, of the receiving hook projects at least partially beyond the plane of the joining surface of the receiving hook, the arresting step and the receiving opening are of such a configuration that the step end during a joining movement initially fits without elastic deformation of the hook profile into the receiving opening to such an extent that the horizontal locking surface of the arresting hook makes contact with a part of its surface with the horizontal locking surface of the receiving hook and the receiving hook has a flexural leg so adapted that the width of the receiving opening can be enlarged by its elastic bendability so that the arresting step can be entirely inserted into the receiving recess and also the arresting contour of the arresting hook is inserted into the positively locking contour of the receiving hook.

Abstract
The invention relates to a panel (1, 2, 27, 28) comprising a body (1′, 2′) having at least one plastic layer, complementary locking means (V) provided in pairs on opposite panel edges, at least one pair of locking means having hook profiles (H), namely a receiving hook (5) and a locking hook opposite thereto, wherein the receiving hook (5) comprises a hook edge (8) disposed away from the body and a receiving recess (9) disposed near the body, wherein the receiving recess (9) is open to the top side (7), wherein the locking hook (6) has a locking recess (11) disposed near the body and open to the bottom side and comprises a locking step (12) disposed away from the body and fitting in the receiving recess (9) of the receiving hook (5) in the vertical joining direction, wherein the locking hook (6) comprises a joint surface (13); away from the body and a vertically active locking contour (14) also away from the body, wherein the receiving hook (5) comprises a joint surface (15) closer to the body and a form-fit contour (16) also closer to the body and fitting together with the locking contour (14) away from the body of the locking hood (6) in a form-fit manner, so that a vertical locking can be brought about, wherein the locking hook (6) comprises a horizontal locking surface (17) disposed closer to the body on the locking step (12) thereof, wherein the receiving hook (5) comprises a horizontal locking surface (18) disposed away from the body in the receiving recess (9), wherein a narrowed receiving opening (19) is formed on the receiving hook (5), through which the locking step (12) can be inserted into the receiving recess (9) substantially in the vertical joint direction (T), wherein the free step end of the locking step (12) is designed narrower than the width of the receiving opening (19) of the receiving hook (5), wherein the locking contour (14) away from the body of the locking hook (6) is short of the plane of the joint surface (13) of the locking hook (6), wherein the form-fit contour (16) closer to the body of the receiving hook (5) protrudes at least partially past the plane of the joint surface (15) of the receiving hook (5), wherein the locking step (12) and the receiving opening (19) are designed so that the step end fits into the receiving opening (19) far enough at first that a part of the horizontal locking surface (17) of the locking hook (6) makes contact with the horizontal locking surface (18) of the receiving hook (5) during a joining motion without elastic deformation of the hook profiles (H), and that the receiving hook (5); comprises a bending bar (20) implemented so that the width of the receiving opening (19) can be expanded by the elastic flexibility thereof, so that the locking step (12) can be inserted entirely into the receiving recess (9) and the locking contour (14) of the locking hook (6) is further inserted into the form-fit contour (16) of the receiving hook (5).
