[0017] The Fig. 1 to 6a show a fastening buckle 0 for straps or belts that are to be releasably connected to one another (not explicitly shown in the figures for reasons of clarity), which is intended or designed in particular for use for helmets, items of clothing, shoes, bags or the like.
[0018] The closure buckle 0 comprises a first closure element 1 which can be connected to a band or strap and a second closure element 2 which can be connected to a band or strap and which interact with each other in a substantially form-fitting and magnetic manner when the closure buckle 0 is in the closed state.
[0019] The first closure element 1 has, on a free section, at least two horizontally and / or vertically spaced-apart projections 1.1 running perpendicular to the longitudinal direction L1 and transverse direction Q1 of the first closure element 1, a groove-like locking receptacle 1.2 running perpendicular to the longitudinal direction L1 and parallel to the transverse direction Q1 of the first closure element 1, perpendicular to the direction of extension of the projections 1.1 of the first closure element 1, and at least one magnet or at least one magnetizable element 1.3.
[0020] The second closure element 2 has, on a free section, at least two horizontally and / or vertically spaced-apart recesses or receptacles 2.1 for a substantially positive-locking reception of the projections 1.1 of the first closure element 1, at the end of the free section a profile-like locking bevel 2.2 running perpendicular to the longitudinal direction L2 and parallel to the transverse direction Q2 of the second closure element 2 for a substantially positive-locking reception in the locking receptacle 1.2 of the first closure element 1, and at least one magnet or at least one magnetizable element 2.3.
[0021] To open the closure buckle 0, the first closure element 1 can be detached from the second closure element 2, or the second closure element 2 can be detached from the first closure element 1 by pivoting or swiveling. Pivoting or swiveling is possible in only one direction, in this case perpendicular to the longitudinal and transverse extension directions L1, Q1, L2, Q2 of the first closure element 1 or the second closure element 2. This advantageously allows the closure buckle 0 to be opened with only one finger of a user or with only one finger movement of a user.
[0022] The second closure element 2 can be pivoted with its locking bevel 2.2 in the locking receptacle 1.2 of the first closure element 1 when the latter is inserted therein, in particular in the manner of a lever.
[0023] The projections 1.1 of the first closure element 1 and the recesses 2.1 of the second closure element 2 have a rectangular or square cross-section in the present case. Other, particularly coordinated, cross-sectional shapes are also provided or possible according to the invention.
[0024] The closure buckle 0 can advantageously be opened or released in only one pivoting direction. Preferably, the first closure element 1 points outward with its cover side 1.6, and the second closure element points inward with its cover side 2.6. Opening occurs from the cover side 2.6 of the second closure element 2 in the direction of the cover side 1.6 of the first closure element 1, particularly preferably with only one of the user's fingers, which is moved or movable in the direction of the cover side 1.6 of the first closure element 1.
[0025] The first closure element 1 and / or the second closure element 2 each has a recess or receptacle for the flat or planar reception of the at least one magnet 1.3, 2.3 or at least one magnetizable element 1.3, 2.3. In the present case, the recess or receptacle runs essentially centrally between the projections 1.1 of the first closure element 1 and the recesses or receptacles 2.1 of the second closure element 2 in the longitudinal direction L1, L2 of the first closure element 1 and the second closure element 2, respectively.
[0026] The first closure element 1 and / or the second closure element 2 each has at least one connecting element 1.5 or 2.5 for the preferably non-releasable fastening or fixing of a band or strap.
[0027] The first closure element 1 and / or the second closure element 2 is made of plastic, metal and / or wood.
[0028] Compared to previously known closure buckles, the closure buckle 0 according to the invention advantageously enables opening with a finger of one hand in or with a single movement directed away from the user. This reduces the psychological and physical strain otherwise required for opening and enables quick and reliable opening. Advantageously, according to the invention, the opening is supported by the user's own weight of the body, arm, hand or finger, so that the force required to carry out this movement with the help of one's own body weight is reduced. Advantageously, no visual observation of or visual contact with the closure buckle 0 or the opening process by the user is required.
