Abstract: A cover for a camera that is mounted to the camera adjacent the camera lens. An exemplary embodiment includes a ring mounted to the camera and a second ring mounted to the first ring. A bag is captured between the first ring and the second ring, and the bag includes a closure proximate an opening for receiving the camera. Embodiments may include a tear-away portion temporarily covering the camera lens. The camera cover may be utilized in an operating room to permit photography within the sterile field, for example.

Abstract: The handlebar for motorcycles (11; 111; 211) according to the invention comprises a light alloy bent tube (2110) to an end of which a twist grip (M) of the motorcycle accelerator can be set. Said end is externally covered by a layer of sliding material substantially harder and more abrasion resistant than the light alloy of said bent tube. Preferably said layer of sliding material comprises a tubular fixed sleeve (263) fitted on said end of the bent tube. The layer of harder material allows better sliding of the twist grip on the light alloy tube end and avoids seizing up thereof.

Abstract: A handlebar (11,111,211) for cycles and motorcycles, in particular for cross-country use, which is light but at the same time resistant to high intensity shocks and stresses and having an optimized elasticity. The handlebar has a median section (13,113) which presents a central portion (23) having a diameter d23 and a thickness s23 for fixing the handlebar; two end sections (15,17), each of them presenting a central portion (27) having a diameter d27 and a thickness s27 for holding the handlebar; and two intermediate sections (19,21), each of them presenting a central portion (25) having a diameter d25 and a thickness s25 linking to the median section (13) in an inner bending zone (24) and to a corresponding one of the end sections (15,17) in an external bending zone (26) having a thickness s26.
