Abstract
Disclosed is a snap-fit connection for construction elements having a construction element, which is connectable to a base element by bringing a first snap-fit element of the construction element into engagement with a second snap-fit element of the base element, the second snap-fit element being located inside an aperture in the base element, characterized in that the first snap-fit element has a bulge-like projection with a bulge diameter and the second snap-fit element has a web-like or shoulder-like projection on at least one wall of the aperture.
Claims14
Snap-fit connection for construction elements having a construction element, which is connectable to a base element by bringing a first snap-fit element (7) of the construction element into engagement with a second snap-fit element (5) of the base element, the second snap-fit element (5) being located inside an aperture (3) in the base element (2), characterised in that the first snap-fit element (7) has a bulge-like projection with a bulge diameter (P1) and the second snap-fit element (5) has a web-like or shoulder-like projection on at least one wall (6) of the aperture (3).
Snap-fit connection according to one of the preceding claims, characterised in that the web-like or shoulder-like projection inside the aperture (3) extends over a shoulder depth (T2) which is smaller than the aperture depth (T1) of the aperture (3).
Snap-fit connection according to one of the preceding claims, characterised in that the web-like or shoulder-like projection is located on the side of the aperture (3) associated with the construction element (1) to be inserted.
Snap-fit connection according to one of the preceding claims, characterised in that the aperture (3) has six walls (6), the web-like or shoulder-like projections being located on two opposing walls (6).
Snap-fit connection according to one of the preceding claims, characterised in that the bulge-like projection of the first snap-fit element (7) extends in a dome shape along a peg (4) which is fixed to the construction element (1).
Snap-fit connection according to one of the preceding claims, characterised in that the peg (4) and the construction element (1) are manufactured integrally, in particular from a flexible plastics material.
Snap-fit connection according to one of the preceding claims, characterised in that the peg (4) is formed with rotational symmetry with a cavity (10) so that upon locating of the peg (4) in the second snap-fit element (5) the peg wall (8) is displaced inwards in the direction of the cavity (10).
Snap-fit connection according to one of the preceding claims, characterised in that on the exterior of the peg wall (8) between the bulge-like projection of the first snap-fit element (7) and the body of the construction element (1) an undercut (9) is formed, which receives the web-like or shoulder-like projection of the second snap-fit element (5) after locating thereof.
Construction element (1) having a peg (4) for a snap-fit connection according to one of the preceding claims, characterised in that the peg (4) has a first snap-fit element (7) with a bulge-like projection having a bulge diameter (P1) and an undercut (9) on the exterior of the peg wall (8) between the bulge-like projection and the body of the construction element (1).
Base element (2) having an aperture (3) for a snap-fit connection according to one of the preceding claims, characterised in that the aperture (3) has a second snap-fit element (5) with a web-like or shoulder-like projection on at least one, in particular on two opposing walls (6) of the aperture (3).
