Abstract
A cutting machine can include a cutting machine body that is movably supported above a table and capable of vertical movement, the cutting machine body can be positioned at an upward waiting position and a lower end position. The cutting machine body can include an auxiliary cover positioned around a portion of a blade and including a projection. When in the upward waiting position the auxiliary cover is not able to move upward because of the position of the projection, and in the lower end position the auxiliary cover is able to move upward.
Claims45
A table cutting machine comprising:
- a table configured to accommodate a workpiece;
- and
- a cutting machine body supported above the table and configured to move in a vertical direction, the cutting machine body including:
- a cover fixed relative to a rotary blade and positioned around an upper edge of the rotary blade,
- a cover movable relative to the rotary blade and configured to open and close as a result of movement of a link lever associated with the vertical movement of the cutting machine body, and
- an auxiliary cover configured to cover a portion of the edge of the rotary blade not covered by the fixed cover and the movable cover,
- wherein a part of the auxiliary cover is configured to removably contact a lower surface of a restriction projection formed on a lower surface of the link lever so as to be prevented from opening when the cutting machine body is at an upper waiting position, and
- wherein the auxiliary cover is configured to move relative to the fixed cover independently of the movement of the link lever.

A cutting machine comprising:
- a table;
- and
- a cutting machine body including a blade, the cutting machine body being movably supported above the table and configured to move vertically, the cutting machine body having at least an upward waiting position and a lower end position, and the cutting machine body including:
- a cover fixed relative to the blade and positioned around a first edge portion of the blade;
- a cover movable relative to the blade and positioned around a second edge portion of the blade, the movable cover being configured to open and close as a result of movement of a link lever associated with the vertical movement of the cutting machine body;
- and
- an auxiliary cover positioned around a third edge portion of the blade and including a projection,
- wherein in the upward waiting position, upward movement of the auxiliary cover is restrained by removable contact between the projection of the auxiliary cover and a lower surface of a restriction projection formed on a lower surface of the link lever,
- wherein in the lower end position, the auxiliary cover is configured to move upward, and
- wherein the auxiliary cover is configured to move relative to the fixed cover independently of the movement of the link lever.

A cutting machine comprising:
- a table;
- and
- a cutting machine body including a blade, the cutting machine body being movably supported above the table and configured to move vertically, the cutting machine body having at least an upward waiting position and a lower end position, and the cutting machine body including:
- a cover fixed relative to the blade,
- a cover movable relative to the blade,
- an auxiliary cover, and
- a link lever configured to be movably engaged with both the fixed cover and the movable cover,
- wherein each cover is positioned around a different edge portion of the blade,
- wherein in the upward waiting position, a part of the auxiliary cover is configured to removably contact a lower surface of a restriction projection formed on a lower surface of the link lever so as to impede upward movement of the auxiliary cover, and
- wherein the auxiliary cover is configured to move relative to the fixed cover independently of the movement of the link lever.
7 more elements
A cutting machine comprising:
- a table;
- and
- a cutting machine body including a circular blade, the cutting machine body being movably supported above the table and configured to move vertically, the cutting machine body including:
- a link lever configured to contact, during movement of the cutting machine body, a cover movable relative to the blade so as to cause movement of the movable cover,
- a cover fixed relative to the blade, and
- an auxiliary cover,
- wherein in an upward waiting position, a part of the auxiliary cover is configured to removably contact a lower surface of a restriction projection formed on a lower surface of the link lever, and
- wherein the auxiliary cover is configured to move relative to the fixed cover independently of the movement of the link lever.
