- Fastening device (1; 101; 201) for releasable fastening of a screen (300), such as a window covering, to a leaf (400), such as a door or a window, wherein the fastening device is provided with coupling means (30; 130; 230) for coupling to the screen, wherein the fastening device is further provided with a housing (10; 110; 210) with a first clamping jaw (11; 111; 211) and with a bracket (20; 220) with a second clamping jaw (21; 221), wherein the bracket is movable in the housing between a clamping position, in which the leaf can be clamped between the first and the second clamping jaw, and a releasing position in which the first and the second clamping jaw release the leaf, wherein the fastening device is further provided with an eccentric locking element (14; 114; 214) which is provided with an operating handle (17; 117; 217) and an eccentrically formed contact surface (16; 116; 216) and is arranged rotatably in the housing, characterized in that in the clamping position the eccentrically formed contact surface (16; 116; 216) lies against the bracket (20; 220) and locks the bracket in the housing in the clamping position.
- Fastening device as claimed in claim 1, wherein the eccentric contact surface (16; 116; 216) co-displaces the bracket (20; 220) during rotation of the eccentric locking element (14; 114; 214) to the clamping position in order to further reduce the distance between the first clamping jaw (11; 111; 211) and the second clamping jaw (21; 221) in the clamping position.
- Fastening device as claimed in claim 1 or 2, wherein the bracket (20; 220) is provided with a rough contact surface for increasing the gripping force of the eccentric locking element (14; 114; 214).
- Fastening device as claimed in claim 3, wherein the bracket (220) is provided with an insert piece (223) with a rough surface, which insert piece can be attached releasably to the bracket.
- Fastening device as claimed in any one of the foregoing claims, wherein the operating handle (17; 117; 217) of the eccentric locking element (14; 114; 214) is generally plate-like and is provided with an eccentric peripheral edge (16; 116; 216).
- Fastening device as claimed in claim 5, wherein the operating handle (17; 117; 217) of the eccentric locking element (14; 114; 214) rests in the clamping position against the rear side of the first clamping jaw (11; 111; 211) of the housing (10; 110; 210).
- Fastening device as claimed in any one of the foregoing claims, wherein the fastening device is further provided with a securing element (30; 130; 230) for securing the eccentric locking element (14; 114) in the clamping position.
- Fastening device as claimed in claim 7, wherein the coupling means (30; 130; 230) comprise the securing element.
- Fastening device as claimed in any one of the foregoing claims, wherein the coupling means (30; 230) are embodied as mounting cover for the cords (302) of a window covering (300), which mounting cover can be attached releasably to the housing (10; 210).
- Fastening device as claimed in any one of the foregoing claims, wherein the coupling means (130) are embodied as mounting support for the shaft of a window covering, which mounting support can be attached releasably to the housing (110).
- Fastening device as claimed in any one of the foregoing claims, wherein the coupling means are embodied as mounting clamp for the rail of a window covering, which mounting clamp can be attached releasably to the housing.
- Fastening device as claimed in any one of the foregoing claims, wherein the housing (10; 110; 210) comprises a first guide piece (12; 112; 212) which is positioned at an angle α to the first clamping jaw (11; 111; 211) and wherein the bracket (20; 220) comprises a second guide piece (22; 222) which is positioned at an angle β to the second clamping jaw (21; 221)
- Fastening device as claimed in claim 12, wherein the housing (10; 110; 210) is provided with a passage (13; 113; 213) for receiving the second guide piece (22; 222), which passage is arranged between the first guide piece (12; 112; 212) and the first clamping jaw (11; 111; 211).
- Fastening device as claimed in claim 13, wherein a rotation axis (15; 115; 215) of the locking element (14; 114; 214) is arranged close to the passage (13; 113; 213) and in the clamping position the eccentrically formed contact surface (16; 116; 216) extends at least partially into the passage.
- Fastening device as claimed in any one of the foregoing claims, wherein the bracket (20; 220) comprises metal, preferably spring steel.
