Abstract
A thermal imaging camera, with an electromechanical shutter device for interrupting the ray path from time to time, has a motor (1), a motor shaft (2) and a shutter flag (3). The motor shaft (2) and the shutter flag (3) are in connection with one another via a crank-and-rocker mechanism. The crank-and-rocker mechanism includes a crank (4) rotatable about the motor shaft (2) with a crank pin (5) and with a rocker (6), at one end of which an elongated hole (8) is provided, which forms a rectilinear sliding joint together with the crank pin (5), and at the other end of which the shutter flag (3) is formed.
Claims10
A thermal imaging camera with an electromechanical shutter device for interrupting a ray path from time to time, the electromechanical shutter device comprising:
- a motor;
- a motor shaft driven by said motor;
- a shutter flag;
- and
- a crank-and-rocker mechanism connecting said motor shaft and said shutter flag, said crank-and-rocker mechanism comprising a crank rotatable about said motor shaft, a crank pin, a rocker and a pivot axis arranged in parallel to said motor shaft, said crank being mounted on the pivot axis, said rocker having an elongated hole forming a rectilinear sliding joint together with said crank pin, with which said rocker is pivoted by a pivot angle between two reversal points with the elongated hole being provided at or adjacent to one end of said rocker and said shutter flag being formed at or adjacent to another end of rocker.
A thermal imaging camera comprising:
- a camera body with an opening providing a ray path;
- an electromechanical shutter device connected to said camera body for interrupting the ray path, said electromechanical shutter device comprising:
- a motor;
- a motor shaft driven by said motor;
- a shutter flag;
- and
- a crank-and-rocker mechanism connecting said motor shaft and said shutter flag, said crank-and-rocker mechanism comprising a crank rotatable about said motor shaft, a crank pin, a rocker and a pivot axis arranged in parallel to said motor shaft, said crank being mounted on said pivot axis, said rocker having a slot forming a rectilinear sliding joint together with said crank pin, with which said rocker is pivoted by a pivot angle between a first reversal point and a second reversal point, said shutter flag being formed at an end of said rocker spaced apart a distance from the slot.
