Abstract
A machine guard assembly for a machine comprising a support, a connection subassembly connected to the support and a guard connected to the connection subassembly, with the guard having a transparent portion. The guard can be raised and lowered relative to the support by the connection subassembly. Furthermore, the guard can be moved towards and away from the support by the connection subassembly and the guard can be rotated relative to the support. The guard can be raised to allow a person to use or attend to the machine and lowered to position the guard between the person and the machine to protect the person, with the guard allowing the person to view the machine through the transparent portion of the guard.
Claims44
A machine guard assembly for a machine comprising:
- a support;
- a connection subassembly connected to the support;
- and
- a guard connected to the connection subassembly, the guard having a transparent portion;
- wherein the guard can be raised and lowered relative to the support by the connection subassembly, the guard can be moved towards and away from the support by the connection subassembly and the guard can be rotated relative to the support;
- and
- wherein the guard can be raised to allow a person to use or attend to the machine and lowered to position the guard between the person and the machine to protect the person, the guard allowing the person to view the machine through the transparent portion of the guard.
The machine guard assembly of claim 4, wherein:
- the connection subassembly is rotatably connected to the support.
A method of safely using a machine for processing parts comprising:
- positioning a machine guard assembly adjacent the machine, the machine guard assembly comprising a support, a connection subassembly connected to the support and a guard connected to the connection subassembly, with the guard having a transparent portion, wherein the guard can be raised and lowered relative to the support by the connection subassembly, the guard can be moved towards and away from the support by the connection subassembly and the guard can be rotated relative to the support;
- positioning the guard between a person using or attending to the machine and the machine;
- processing a part;
- raising the guard to allow the person to have access to the part in the machine;
- removing the part from the machine;
- and
- lowering the guard to position the guard between the person and the machine.
