Helmet camera system, fastening device, helmet system, and camera system

A fastening device for a helmet camera system with a helmet and with a camera, the fastening device comprising:

• a helmet holding device configured to be fastened to the helmet;
• a camera holding device configured to be fastened to the camera,
• wherein the helmet holding device and the camera holding device are configured to provide a non-positive and/or positive-locking connection for holding the camera at the helmet,
• wherein the helmet holding device has a toothed ring having internal teeth and the camera holding device has two toothed ring segments having external teeth,
• wherein the toothed ring segments can be positioned in the toothed ring for establishing the non-positive and/or positive-locking connection between the helmet holding device and the camera holding device, wherein the two toothed ring segments are positioned opposite each other;
• and
• an adjusting device for manually adjusting the two toothed ring segments in a radial direction of the toothed ring segments between a held state for establishing the non-positive and/or positive-locking connection and a released state for severing the non-positive and/or positive-locking connection, wherein the adjusting device is configured for adjusting the two toothed ring segments in a same adjustment direction, wherein in a held state the adjusting device fixes a position of the two ring segments to prevent rotation of the camera holding device relative to the helmet holding device and in a released state the adjusting device determines a position of the two ring segments to allow rotation of the camera holding device relative to the helmet holding device;
• a locking device for establishing a locking connection between the helmet holding device and the camera holding device in the held state, wherein the locking device is configured to axially limit movement of the camera holding device relative to the helmet holding device in the held state;
• and
• a magnet device for establishing a magnetic connection force between the helmet holding device and the camera holding device in the held state and in the released state, wherein the magnet device inhibits axial movement of the camera holding device relative to the helmet holding device in both the held state and the released state.

A helmet system for a helmet camera system comprising a camera and a camera holding device fastened to the camera, the camera holding device having two toothed ring segments having external teeth, the helmet system comprising:

• a helmet, wherein the helmet comprises a head protection shell;
• a helmet holding device fastened to the helmet, wherein the helmet holding device has a toothed ring having internal teeth and is configured to establish a non-positive and/or positive-locking connection to the camera holding device for holding the camera at the helmet;
• wherein the toothed ring is configured to receive the toothed ring segments for establishing the non-positive and/or positive-locking connection between the helmet holding device and the camera holding device, wherein the two toothed ring segments are positioned opposite each other;
• an adjusting device for manually adjusting the two toothed ring segments in a radial direction of the toothed ring segments between a held state for establishing the non-positive and/or positive-locking connection and a released state for severing the non-positive and/or positive-locking connection, wherein the adjusting device is configured for adjusting the two toothed ring segments in a same adjustment direction, wherein in a held state the adjusting device fixes a position of the two ring segments to prevent rotation of the camera holding device relative to the helmet holding device and in a released state the adjusting device determines a position of the two ring segments to allow rotation of the camera holding device relative to the helmet holding device;
• a locking device for establishing a locking connection between the helmet holding device and the camera holding device in the held state, wherein the locking device is configured to axially limit movement of the camera holding device relative to the helmet holding device in the held state;
• and
• a magnet device for establishing a magnetic connection force between the helmet holding device and the camera holding device in the held state and in the released state, wherein the magnet device inhibits axial movement of the camera holding device camera relative to the helmet holding device in both the held state and the released state,
• wherein the helmet holding device is formed at the head protection shell, wherein the helmet holding device is configured as an integral component of the head protection shell.

A camera system for a helmet camera system comprising a helmet comprising a head protection shell and a helmet holding device fastened to the helmet, the helmet holding device having a toothed ring having internal teeth, the camera system comprising:

• a camera comprising a camera housing;
• a camera holding device fastened to the camera, wherein the camera holding device comprises two toothed ring segments having external teeth and configured to establish a non-positive and/or positive-locking connection to the helmet holding device for holding the camera at the helmet,
• wherein the two ring segments is configured to be positioned in the toothed ring for establishing the non-positive and/or positive-locking connection between the helmet holding device and the camera holding device, and
• wherein the camera holding device is formed at the camera housing and the camera holding device is configured as an integral component of the camera housing;
• an adjusting device for manually adjusting the ring segments in a radial direction of the toothed ring segments between a held state for establishing the non-positive and/or positive-locking connection and a released state for severing the non-positive and/or positive-locking connection, wherein the adjusting device is configured for adjusting the toothed ring segments, wherein in a held state the adjusting device rotationally fixes a position of the ring segments to prevent rotation of the camera holding device relative to the helmet holding device and in a released state the adjusting device determines a position of the ring segments to allow rotation of the camera holding device relative to the helmet holding device;
• and
• axial retaining means configured to axially limit movement of the camera holding device relative to the helmet holding device in the held state.
