Abstract: The present invention relates to an optical component holder (1) for assembling a lighting device (20), the optical component holder (1) comprising at least one flexible flap (5) being attached to an edge portion (4) extending substantially in a transversal plane. The at least one flexible flap (5) comprises a locking snap-fit arrangement (6) and a releasing portion (9). The optical component holder (1) further comprises a housing connection (10) for attaching the optical component holder (1) to the lighting device (20) and a releasing element (12) for releasing the locking element (11). The locking snap-fit arrangement (6) comprises a contact surface (6?) facing the edge portion (4). The lower portion (8) of the locking snap-fit arrangement (6) is movable between a locked position and an unlocked position in the longitudinal plane.

Abstract: This invention relates to a modular and removable integration technique for a luminaire (100) on an adaptor plate (201) with a general area lighting rail system (202). The luminaire (100) comprises, a mounting system (200), a lighting device (300), and a mounting device (400). The mounting system (200) comprises an adaptor plate (201) that can be attached to a rail system (202). The lighting device (300) comprises a shaft (301) that is 5 configured to have a lamp (302) on a first end and a flange (303) on a second end. The mounting device (400) comprises at least a pair of interface plugs (401, 402). The pair of interface plugs (401, 402) is configured to be attached together to form an inner perimeter (403) around a hollow space and the inner perimeter (403) can embrace the second end of the shaft (301) that is received through an opening (203) of the adaptor plate (201). The inner 10 perimeter (403) is substantially the same or larger than an outer perimeter of the shaft, but smaller than the flange (303).

Abstract: The invention is a foot-propelled wheeled hobby and/or sport device which has a central wheel (1), a frame (4) including side plates (20) connected to each other and located on both sides of the central wheel (1) at a distance from it and foot plates (5) on the lower part of the side plates (20) protruding outwards from them, located below the wheel axle (6) which has a wheel hub (2) and, furthermore, a satellite wheel (7), connected to the frame (4), with a diameter smaller than the central wheel (1). The essence of the invention is that from the point of view of the main propelling direction of the device the satellite wheel (7) is located in front of the central wheel (1). The frame (4) has front and rear frame members (21a, 21b) stiffening the side plates (20), running along their side edges opposite each other. Stable stiffening members are connected at the end parts of the foot plates (5) to the lower ends of the frame members (21a, 21b).

Abstract: The invention relates to a foot-propelled wheeled hobby and/or sport device which has a wheel (1) situated between two side-plates (2; 3), and the side-plates (2; 3) are suspended on the axle (X) of the wheel (1). Foot-boards (5) situated below the axle (X) of the wheel (1). Foot-boards (5) situated below the axle (X) of the wheel (1), protruding outwards are connected to the side-plates (2; 3). In the course of the appropriate use of the device (I; II) the side-plates (2; 3) project over the knee of the user (12) standing on one or both of the foot-boards (5), providing a supporting surface (a) for the knee. The invention is based on that at a certain distance (e) behind the wheel (1)—with respect to the travelling direction—there is a structure in the range of the track of the wheel (1) ensuring stabilisation against tilting, and in order to relieve the knees of any load the side-plates (3) are constructed with a height (L) ensuring a supporting surface (b) for the user's (12) thigh.
