Pendulum guide device for a jigsaw blade that executes reciprocating motions

1. A pendulum guide device for a power jigsaw saw blade that executes reciprocating motions, comprising:

guide elements that engage a saw blade spine of the saw blade and are associated with a support frame,

wherein the guide elements comprise at least two guide elements ( 7 ), wherein one of said at least two guide elements is fixed in place on the support frame and wherein the other of said at least two guide elements is bearing-mounted to the support frame ( 8 ) in moving fashion and is prestressed in the direction toward the saw blade spine ( 6 ),

wherein the guide element ( 7 ) that is fixed in place on the support frame is a first guide roller ( 11 ), wherein the movably bearing-mounted guide element ( 7 ) is a second guide roller ( 12 ), and

wherein the second guide roller ( 12 ) is bearing-mounted in an oscillating retainer ( 10 ) that is bearing-mounted to the support frame ( 8 ) so that it is moveable in an oscillating fashion on a rotation axis of the first guide roller; and

at least one helical compression spring, wherein said at least one helical compression spring is configured to produce a prestressing, wherein said at least one helical compression spring rests with one end against the support frame and with another end against the oscillating retainer, whereby the support frame and the oscillating retainer provide a deflection limiter that limits an amount of travel of the oscillating retainer in a direction of the saw blade, such that an undesirably large amount of travel in the direction of the saw blade is prevented.

2. The pendulum guide device as recited in claim 1 , wherein the guide element ( 7 ) that is fixed in place on the support frame is rotatably mounted to the support frame ( 8 ) by means of a bearing ( 21 ).

3. The pendulum guide device as recited in claim 2 , wherein the bearing ( 21 ) is a needle bearing ( 22 ).

4. The pendulum guide device as recited in claim 1 , wherein at least the second guide roller ( 12 ) has an essentially V-shaped guide notch ( 26 ) on its outer circumference.

5. The pendulum guide device as recited in claim 1 , wherein the oscillating retainer ( 10 ) has two oscillating arms ( 23 , 24 ) between which the first guide roller ( 11 ) and/or the second guide roller ( 12 ) is/are accommodated.

6. The pendulum guide device as recited in claim 5 , wherein the two oscillating arms ( 23 , 24 ) are each prestressed in the direction toward the saw blade spine ( 6 ).
