Abstract
The workspace is sufficiently secured while controlling the occupied space. A toggle clamp includes: an actuator capable of linear reciprocating movement of a first shaft; a base plate having an arc-shaped long hole in which the first shaft is slidably fitted; a clamp arm; a base member that rotatably supports the base plate via a second shaft and rotatably supports the clamp arm via a third shaft; and a link member rotatably connected to the clamp arm via a fourth axis and rotatably connected to the base plate via a fifth shaft. In the released state, the fourth shaft is located away from a straight line connecting respective axis centers of the second and fifth shafts. In the fixed state, the fourth shaft is located on a straight line connecting the second and fifth shafts.
Claims2
A toggle clamp for detachably securing a clamped object using a toggle mechanism, the toggle clamp comprising:
- an actuator configured for linear reciprocating movement of a first shaft in a direction orthogonal to the first shaft;
- a base plate having an arc-shaped long hole in which the first shaft is slidably fitted;
- a clamp arm having a clamping action portion provided at one end of the clamp arm, the clamping action portion being configured to press against the clamped object;
- a base member that rotatably supports the base plate via a second shaft and rotatably supports the clamp arm via a third shaft;
- and
- a link member that is rotatably connected to the clamp arm via a fourth shaft located away from the third shaft toward the clamping action portion, and rotatably connected to the base plate via a fifth shaft,
- wherein the base plate, the clamp arm, the base member and the link member together constitute the toggle mechanism,
- wherein, when the clamping action portion is in a released state in which the clamped object is releasable, the fourth shaft is located away from a first straight line connecting respective axis centers of the second shaft and the fifth shaft toward the clamping action portion, and
- wherein when the clamping action portion is in a fixed state in which the clamped object is fixable, the fourth shaft is located on the first straight line connecting respective axis centers of the second shaft and the fifth shaft.
