Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
201 words
A saw table for a compass saw formed particularly as a hand-held power tool, the saw table comprising a table plate having an edge and extending so that a compass saw is located under said table plate and a saw blade extends upwardly beyond said table plate at a predetermined location spaced from said edge, the saw blade being inclinable between a plurality of cutting angles and engageable between a plurality of cutting depths; means forming an air guiding passage; holding means extending from said edge of said table plate to said location and above said table plate, at a distance from the latter at said location; and protecting means for protecting the saw blade, said protecting means being held by said holding means which extends from said edge to said location above said table plate, overlapping the saw blade from a space above said table plate, being formed as an end piece of said air guiding means, and being arranged movable in direction of the saw blade, said protective means including a protective hood arranged to surround the saw blade and having an inner dimension corresponding to all cutting angles and depths of the saw blade with a sufficient play.
Claim 2
Dependent Claim
201 words
A saw table for a compass saw formed particularly as a hand-held power tool, the saw table comprising a table plate having an edge and extending so that a compass saw is located under said table plate and a saw blade extends upwardly beyond said table plate at a predetermined location spaced from said edge, the saw blade being inclinable between a plurality of cutting angles and engageable between a plurality of cutting depths; means forming an air guiding passage; holding means extending from said edge of said table plate to said location and above said table plate, at a distance from the latter at said location; and protecting means for protecting the saw blade, said protecting means being held by said holding means which extends from said edge to said location above said table plate, overlapping the saw blade from a space above said table plate, being formed as an end piece of said air guiding means, and being arranged movable in direction of the saw blade, said protective means including a protective hood arranged to surround the saw blade and having an inner dimension corresponding to all cutting angles and depths of the saw blade with a sufficient play.
Claim 3
Dependent Claim
23 words
A saw table as defined in claim 1, wherein said protective hood is mounted nonrotatably and displaceable normal relative to said saw table.
Claim 4
Dependent Claim
27 words
A saw table as defined in claim 2, wherein said holding means and includes a traverse, and a hollow piece connecting said protective hood with said traverse.
Claim 5
Dependent Claim
43 words
A saw table as defined in claim 3, wherein said air guiding passage is formed as a dust aspirating means, said traverse having a first end portion connected with said hollow piece, and a second end portion connectable with said dust aspirating means.
Claim 6
Dependent Claim
45 words
A saw table as defined in claim 3, wherein said protective hood of said hollow piece is held in said traverse so easily that said protective hood is suppored on said table plate or a workpiece under the action of weight of said protective hood.
Claim 7
Dependent Claim
21 words
A saw table as defined in claim 3, wherein said protective hood of said protecting means is provided with a handle.
Claim 8
Dependent Claim
40 words
A saw table as defined in claim 6, wherein said protecting means has an inclined sliding face arranged so that when a workpiece displaces in a feed direction, it lifts by its thickness said protecting means from said table plate.
Claim 9
Dependent Claim
29 words
A saw table as defined in claim 7, and further comprising means for connecting said handle with said protective hood and including a web provided with said inclined face.
Claim 10
Dependent Claim
191 words
A saw table for a compass saw formed particularly as a hand-held power tool, the saw table comprising a table plate having an edge and extending so that a compass saw is located under said table plate and a saw blade extends upwardly beyond said table plate at a predetermined location spaced from said edge; means forming an air guiding passage; holding means extending from said edge of said table plate to said location and above said table plate, at a distance from the latter at said location; protecting means for protecting the saw blade, said protecting means being held by said holding means which extends from said edge to said location above said table plate, overlapping the saw blade from a space above said table plate, being forced as an end piece of said air guiding means, and being arranged movable in direction of the saw blade, said protecting means being liftable and lowerable in a direction substantially normal to said table plate within a predetermined movement region; and switching means associated with said protecting means and having a switch member arranged in said movement region of said protecting means.
