Abstract
A safety guard device for a power tool discharge chute which includes a shaft attached to the chute and extending across the opening of the chute. There are a plurality of elongate spaced-apart blade elements mounted to the shaft for pivoting within the chute and one or more springs or other resilient elements are provided for biasing the blade elements into a closed condition within the chute to prevent operator access through the opening of the chute and permitting the blades to pivot into an open condition so that bulky material may be discharged through the chute.
Claims23
A safety guard device for a power tool discharge chute, comprising:
- shaft means attached to the chute and extending across the opening of the chute;
- a plurality of elongate spaced apart blade elements mounted to said shaft means for pivoting within said chute;
- and
- resilient means for biasing said blade elements into a closed condition within the chute to prevent operator access through the opening of the chute and permitting said blades to pivot into an open condition so that bulky material may be discharged through the chute.
A safety guard device for a snow thrower discharge chute comprising:
- shaft means attached to the chute and extending across the opening of the chute;
- a plurality of elongate spaced apart blade elements mounted to said shaft means for pivoting within said chute;
- and
- resilient means for biasing said blade elements into a closed condition within the chute to hinder operator access through the opening of the chute and permitting said blades to pivot into an open condition so that bulky material may be discharged through the chute.
A safety guard device for a power tool discharge chute, comprising:
- shaft means attached to the chute and extending across the opening of the chute;
- a plurality of elongate spaced apart guard elements mounted to said shaft means for pivoting within said chute, said guard elements being thin relative to the spacing therebetween for permitting unhindered discharge of fine material through the guard element in the closed condition;
- resilient means for strongly biasing said guard elements into a closed condition within the chute to prevent operator access through the opening of the chute and permitting said guard elements to pivot into an open condition so that bulky material may be discharged through the chute;
- and
- means for pivotably mounting said guard elements on said shaft means, and said resilient means including a plurality of resilient elements, each being interconnected between said shaft means and a respective said guard element, for enabling said guard elements to be independently pivotable.
