Now with reference to the drawings, in the same numerals denote like components, shows 1 a miter saw 10 , which generally a pedestal 12 comprising a movable support arm 14 , which is pivotally mounted on the base, and a motor-driven saw unit 16 , As shown, the power saw unit is 16 an electric saw with a circular saw blade 18 , The base 12 is configured to support a workpiece and, in one embodiment, the socket includes a slot grid 20 to keep the workpiece reliable. The miter saw is designed so that the position of the saw blade 18 can be changed to cut the workpiece.
For an angular adjustment of the saw blade 18 at a "miter angle" around a vertical miter axis M, still referring to 1 , points the pedestal 12 a stationary part 22 which is stored on a stationary surface such as a workbench (not shown) and a turntable 24 which rotatably on the stationary part 22 is mounted. The position of the turntable 24 corresponds to the miter angle of the saw blade 18 relative to the slot grid 20 on the pedestal 12 , A rotatable handle 26 is provided for moving the turntable to a selected miter angle.
The arm 14 facilitates the movement of the saw blade 18 relative to the turntable 24 , So the tool unit 16 can be pivoted about a "chamfer angle" about a horizontal chamfer axis B, the support arm 14 a chamfering arm or first arm part 14A up, rotatable on the turntable 24 is mounted to allow a rotation about the Bechungsachse B around. The arm 14 also has a second arm part 14B on, the first arm part 14A on an elbow 28 is pivotally mounted, so that the saw blade 18 can be moved generally downwards in the direction of the turntable.
Optionally, the first arm part 14A horizontal sliding rails 30 to allow the tool unit to be moved in a sliding movement along a horizontal section line in the manner of a radial arm saw. To allow an operator to move the arm to a desired position and the saw blade 18 maneuver, the arm points 14 a switching handle 100 on. As in 1 shown is the switching handle 100 on the second arm part 14B generally on a front side of the saw 10 mounted near the operator for easy handling. The switching handle 100 has a shape that is comfortable to grip. Regarding 1 and 3a is the handle 100 generally D-shaped including a mounting part 102 which is mounted on the arm and a handle part 104 which is comfortable to grip. The switching handle 100 has a switch which has a movable trigger for actuating the motor-driven saw unit 16 contains.
The switching handle 100 is mounted in such a way that an optionally rotatable adjustment in an ergonomically suitable position relative to the arm 14 allowing for easy handling of the saw in different bevel angles and different operating modes. Because the saw 10 can be operated in different possible chamfer angles and with different cutting movements (for example horizontally sliding movement on the rails 30 of the first arm part 14A or pivoting cutting movement by pivoting the second arm part 14B at the elbow 28 ) it is desirable for the user to use the handle 100 in a comfortable gripping position, depending on the specific operation.
The miter saw has a latching mechanism around the handle 100 in positions specifically designed for use with commonly used chamfer angle settings of -45 ° (counterclockwise), 0 ° (vertical), and 45 ° (clockwise). Because the handle 100 with the first arm part 14A tilts while the chamfer angle is adjusted, the predetermined handle positions provide a generally vertical or horizontal orientation of the handle portion 104 even when the arm is set to a chamfer angle of 45 ° to the left or right. It has been found that such handle orientations are ergonomically desirable under various conditions. The handle 100 For example, it may refer to a selected one of four different rotational positions in 45 ° increments as in 2a to be set to d which the saw in different bevel angle positions of the arm 14 demonstrate. As in 2a shown, measured when the arm 14 is set to a 0 ° chamfer angle position for a vertical cut, is the handle 100 positioned so that the handle portion is aligned horizontally. As in 2 B shown, the handle can 100 in a clockwise position to 45 °, so that a horizontal orientation of the handle part is provided on the handle, provided the arm 14 counterclockwise to a chamfer angle of -45 °.
Unless the arm 14 is set to a bevel angle clockwise of 45 °, such as in a double compound miter saw, the handle 100 in a position turned counter-clockwise at -45 °, so that the handle part is still provided with a horizontal orientation as in 2c shown. 2d illustrates the handle 100 , where it is rotated by + 90 °, provided that the arm is back to a 0 ° chamfer angle, the handle part in a general My vertical orientation is available, which can be desired.
It has been found that a horizontal orientation of the handle part ( 2a . 2 B . 2c ) is sometimes ergonomically desirable, provided that the saw is used, with a pivotal movement of the second arm part 14B relative to the first arm part 14A at the elbow 28 ( 1 ) to cut in the manner of a hacksaw even at different chamfer angles. It has also been found that the vertical orientation of the handle ( 2d ) is sometimes ergonomically desirable, as long as the saw is used as a radial arm saw in a forward-backward cutting motion. Of course, the notches for any desired angle and handle positions in addition to those in 2a to be designed to d.
Yourself now 3a . 3b and 4 turning, the switching handle becomes 100 be described in more detail. The mounting part 102 The handle projects in a general reverse direction and can from the center of the handle 100 be offset. side members 106 extend forward to the handle part 104 , The side components 106 can be angled so that as shown, the handle portion down against the mounting part 102 is offset. For example, in one embodiment, the side members 106 arranged at an angle of about 20 °. The trigger 108 has a generally elongated shape and protrudes specifically from an inside of the handle part 104 out. An electric switch 112 ( 3b ) is in the handle part 104 for actuating the motor-driven sawing unit 16 ( 1 ), provided the trigger 108 is squeezed. The handle 100 preferably also includes a pair of safety lock buttons 110 of which at least one must be actuated before the trigger 108 can be squeezed.
A proximal end of the arm 14 has a hub 32 on, at which the handle 100 adjusted. As shown, the hub is 32 a two-piece member generally cylindrical in shape and an inner recess 34 pretends. The leads to the switch actuated by the trigger 112 can the depression 34 run through. In addition, a locking collar 200 made precisely concentric around the contacting parts of the hub 32 and the handle 100 fits.
Now referring to 6 it is shown that the mounting part 102 an outwardly projecting lip 114 which is in a depression of the hub 32 fits, and allows a relative movement. An annular lip 36 which is from the hub 32 stands out, specifies the recess. Because the hub 32 assembled from two halved components, the lips can be positioned in an entangled manner. To the structure of the handle 100 and the hub 32 to complete, is the locking collar 200 cooperating with the hub 32 and the mounting part 102 formed to effect a positive and secure fit. As in the 6 and 7 shown, points the hub 32 a first annular locking flange 38 on the outside at one end of the hub 32 protrudes and the mounting part 102 of the handle 100 includes a second annular locking flange 138 which is out of the handle 100 protrudes outwards. Each of the flanges 38 and 138 has a beveled side and a planar side. The respective planar sides are positioned to contact each other in alignment, as shown, such that the chamfered sides generally point in opposite directions. An inside of the locking collar 200 contains a kind of conical annular recess to accommodate the locking flanges. The conical annular recess contacts the chamfered sides to urge the planar sides together. The resulting severe friction results in a robust assembly of the handle 100 at the hub 32 ,
To select rotary adjustments of the handle 100 to allow the locking collar 200 optionally be released from the locking flanges or tightened, as in the respective 8a and 8b shown. Regarding 8a owns the locking collar 200 two generally semicircular left and right parts 202 and 204 , The semicircular parts 202 . 204 have respective first ends that have a hinge 210 connected to each other. The semicircular parts 202 . 204 have respective second ends hinged to a clamp, which first and second levers 211 . 212 has. The first lever 211 has a base end hinged to the left semi-circular part 202 connected and the second lever 212 has a base end hinged to the right semicircular part 204 connected is. To press the second ends of the left and right semicircular parts together in a closed position, as in FIG 8b shown, the first lever points 211 a distal end hinged to an intermediate position of the second lever 212 is mounted.
As in the 8a and 8b shown is the first lever 211 swiveling over a pin 214 attached to the semicircular part. To the tension of the collar 200 to adjust, the lever owns 211 a pair of threaded adjustment screws 214 which the pen 216 to contact. By changing the axial positions of the threaded adjustment screws 214 is the geometry of the leverage, which passes through the first and second levers 211 and 212 is formed, changed, what the tension of the semicircular parts 202 . 204 in the closed position of 8b affected.
8th illustrates the locking collar 200 in an open position, in which the collar is loose relative to the hub 32 and the handle 100 is, wherein in a second position, the collar around the contacting parts of the hub 32 and the handle 100 is narrowed around.
In one embodiment, the locking collar fits 200 on the hub 32 to a relative rotation of the locking collar 200 to prevent. Like in the 6 and 7 shown, the hub points 32 a pair of noses 40 on, and the locking collar 200 has a pair of complementary depressions, which are the noses 40 pick up to prevent relative rotation.
The handle 100 is movable to predetermined rotational positions relative to the arm as described above with reference to the exemplary handle positions shown in FIG 2a to d are discussed. A detent mechanism is provided to provide selected rotational stop positions at the predetermined locations. More specifically, with respect to the 4 and 5 is a catch component 42 at the hub 32 inside an inner recess 34 assembled. The locking component 32 is generally C-shaped and has a plurality of detent slots 42A . 42B . 42C , and 42D ( 5 ), which in a generally radial direction relative to the hub 32 are aligned. In one embodiment, the locking member sits 42 safely within a latching recess 44 ( 5 ), inside the hub 32 is formed.
Likewise in the 3a . 3b . 4 . 9a and 9b pictured is a lever 116 swiveling on the handle 100 mounted to be operated by an operator. The lever 116 contains a detent pin 118 that is aligned so that it is in the slots 42A to D ( 5 ) of the locking component 42 extends in and out of this, preferably in a generally radial movement. lever 116 is between a locking position ( 9a ) movable, in which the locking pin 118 detects one of the locking slots and an unlocked position ( 9b ), in which the locking pin 118 from the locking component 42 is disengaged. In the locked position ( 9a ) is the handle 100 stuck and can not relative to the hub 32 twist. In the unlocked position ( 9b ) the handle can 100 relative to the hub 32 be twisted into another selected location. A biasing member or a spring 130 ( 3b and 4 ) is inside the handle 100 attached to the lever 116 to preload in order to urge the detent pin into the locked position ( 9a ). So that the detent pin 118 just the respective slots 42A can find to D, the sides of each of the locking slots are chamfered away from each other in the direction of a center of the locking member.
If the detent pin 118 a selected one of the detent slots 42A Detected until D, the handle is in a corresponding angular position relative to the hub 32 set in the in 4 . 9a and 9b example shown:
If the detent pin the slot 42A detected, is the handle 100 in a horizontal position (with respect to a vertical saw orientation), as in 2a shown; provided the locking pin 118 the slot 42B detected, is the handle 100 in a position 45 ° clockwise, as in 2 B shown; provided the detent pin the slot 42C detected, is the handle 100 in a position 45 ° clockwise, as in 2a shown; and if the detent pin the slot 42D detected, is the handle 100 in a position 90 ° clockwise, as shown in 2D ,
To improve safety, in one embodiment, the trigger is 100 on the operation of the motor operated sawing unit 16 hindered, provided the handle 100 not in a locked position. For example, with respect to the 9a and 9b contains the lever 116 as well as a lead 120 which is the movement of the trigger 100 obstructed to prevent operation of the power switch, provided that the lever is in the unlocked position ( 9b ) and the projection gives the trigger 108 free, provided that the lever is in the locked position ( 9a ). Especially has the trigger 108 a prong 122 which protrudes upwards and provided the lever 116 is pivoted in the unlocked position, the projection moves 120 behind the tines 122 and thus blocks the movement of the trigger in the squeezing direction. Likewise blocked the projection, if the trigger 108 the lever is pressed 116 in that it can subsequently be moved to the unlocked position.
In one embodiment, the pivotable detent pin is 118 configured to stand between the detent slots 42A until D can move by turning the handle under the action of a torsional force. Such an embodiment avoids the need for manual operation of the lever 116 and accordingly, the invention includes an embodiment in which the lever has no externally accessible part for gripping by the user. More specific are the slots 42A to D and / or the latch pin are formed with appropriate angles or curves so that a supply of rotation causes the latch pin to move radially to one of the slots 42A to release D. To the handle 100 to another Adjust the locking position, the torsion must be sufficient to overcome the bias of the spring force against the locking pin radially outward. In such an embodiment, the locking collar becomes 200 released into its open position ( 8a ) before the rotary adjustment of the handle is complete and the collar 200 is then clamped in its locked position ( 8b ) after the desired turning adjustment has been carried out.
