Definitions
- the present invention relates to a flip over saw according to the preamble of claim 1 including a main body having a saw blade driven to rotate and a table at which the main body is held movable up and down, and a base at which the table and the main body are held rotatable 180 degrees.
- the flip over saw can be used as a miter saw when the main body is positioned over the table, and can be used as a table saw when the main body is positioned under the table protruding the saw blade over the table.
- a conventional flip over saw has a rectangular mounting base on which a table is horizontally supported rotatable 180 degrees around a center portion of the table and capable of being secured even if either one or the other surface of the table faces upwardly.
- a main body is pivotally mounted movable up and down, and the main body has a saw blade which rotates driven by a motor.
- the flip over saw can be used as a miter saw when the main body is positioned over the table, in which the main body is lowered to cut a workpiece disposed on the table.
- the flip over saw can be used as a table saw when the main body is positioned under the table by rotating the table with a condition that the saw blade is secured at a bottom dead center to penetrate the table downwardly.
- a workpiece on the table can be slid with respect to the saw blade and cutting is conducted.
- the U. S. Patent No. 5787779 discloses a well-known structure.
- a heavyweight motor is located at the rear side of the table when it is used as a miter saw, so that the table is unbalanced and prone to rotate.
- malfunctional table rotation might damage the table and the main body.
- the reverse operation of the table becomes hard since the center of gravity of the table being far from the center of rotation generates a large centrifugal force in reversing, thereby lowering operability.
- US 4,531,441 , US 3,570,564 and EP 0 271 755 A1 disclose flip over saws which are a combined table and miter saw. By rotating a horizontal table supported on a base the saw can be switched from a miter saw mode to a table saw mode.
- a main body is supported by a support arm provided on one side of the table and has a saw blade driven to rotate by a motor.
- the motor is respectively disposed behind the center of rotation of the table with respect to the base when regarded in a cutting direction in the miter saw mode and at a top dead center of the main body.
- EP 0 586 172 A2 which forms the preamble of claim 1 discloses a pivoting power tool with a table.
- the table is pivotable about an axis with respect to a frame, which axis moves along an arc between two end positions which it assumes in the miter saw mode and the table saw mode, respectively.
- the motor which is provided on a support arm is positioned behind the center of rotation.

- the center of motor is located in front of the center of rotation of the table with the main body being at the top dead center in a miter saw mode in order to prevent the accidental rotation of the table more effectively.
- the main body is pivotally mounted on a support arm via a support shaft rotatably in the upper and lower direction. Then, the distance between the center of rotation of the table and the center of motor is shorter than that between the center of rotation of the table and the center of the support shaft with the main body being at a bottom dead center in a miter saw mode in order to obtain excellent operability in reversing the table from the miter saw mode position to the table saw mode position.
- the table since the table is well-balanced in the miter saw mode, the table is protected from being reversed even if locking of the table is released by malfunction. As a result, damage to the table and the main body caused by accidental reverse of the table can be prevented. In addition, since the center of gravity is positioned near the center of rotation, the table's reverse operation becomes easier, thereby improving operability.
- reversing of the table for conversion to the table saw mode is conducted by flipping up the front part of the table upwardly.
- the center of gravity is positioned to the front, thereby preventing the accidental reverse of the table from the miter saw mode more effectively.
- the motor is closer to the center of rotation of the table the moment of inertia in reversing becomes small, so that reversing can be conducted easily with a light pressure. Therefore, an excellent operability can be achieved in reversing the table upon conversion from the miter saw mode to the table saw mode.

- the table 3 is secured by means of a stopper mechanism 6 with the saw blade unit 4 raised as shown in Figs. 1-3 . Then the handle 14 is held to lower the main body 11 in which the blade saw 15 is rotating, so that a workpiece disposed on the turntable 7 can be cut, specifically, the bevel cutting by tilting the main body 11 and the miter cutting by horizontally turning the turntable 7 are achieved.
- the center of gravity of the main body 11 is substantially positioned at the center of the table 3 in the longitudinal direction (that is, adjacent to the rotating shaft 5). Therefore, the accidental reverse of the table 3 can be prevented even if the stopper mechanism 6 is released by malfunction and so on.
- conversion into the table saw mode is conducted as follows. First, the main body 11 is lowered to the bottom dead center to be secured by the locking mechanism 18. Then the stopper mechanism 6 is released and the table 3 is turned 180 degrees in the direction where the front part of the table is flipped up until the table 3 is stopped at the reverse position abutting the second stopper rubbers 21, 21. Likewise, upon conversion into the miter saw mode, the table 3 is turned 180 degrees in the direction where the rear part of the table is flipped up until the table 3 is stopped at the reverse position abutting the first stopper rubbers 20, 20. In these reverse operations, the motor 13 of the main body 11 locked at the bottom dead center is further closer to the rotating shaft 5 in addition to above-described location. Consequently, the moment of inertia upon reversing becomes smaller, so that the reverse can be conducted easily with a light pressure.

Abstract
Description
- The present invention relates to a flip over saw according to the preamble of
claim 1 including a main body having a saw blade driven to rotate and a table at which the main body is held movable up and down, and a base at which the table and the main body are held rotatable 180 degrees. The flip over saw can be used as a miter saw when the main body is positioned over the table, and can be used as a table saw when the main body is positioned under the table protruding the saw blade over the table. - A conventional flip over saw has a rectangular mounting base on which a table is horizontally supported rotatable 180 degrees around a center portion of the table and capable of being secured even if either one or the other surface of the table faces upwardly. Moreover, on one side of the table a main body is pivotally mounted movable up and down, and the main body has a saw blade which rotates driven by a motor. With this configuration, the flip over saw can be used as a miter saw when the main body is positioned over the table, in which the main body is lowered to cut a workpiece disposed on the table. On the other hand, the flip over saw can be used as a table saw when the main body is positioned under the table by rotating the table with a condition that the saw blade is secured at a bottom dead center to penetrate the table downwardly. In a table saw mode, a workpiece on the table can be slid with respect to the saw blade and cutting is conducted. As this kind of flip over saw, the
U. S. Patent No. 5787779 discloses a well-known structure. - In such a flip over saw as described in the above patent, a heavyweight motor is located at the rear side of the table when it is used as a miter saw, so that the table is unbalanced and prone to rotate. With this configuration, malfunctional table rotation might damage the table and the main body. In addition, the reverse operation of the table becomes hard since the center of gravity of the table being far from the center of rotation generates a large centrifugal force in reversing, thereby lowering operability.

US 4,531,441 ,US 3,570,564 andEP 0 271 755 A1 disclose flip over saws which are a combined table and miter saw. By rotating a horizontal table supported on a base the saw can be switched from a miter saw mode to a table saw mode. A main body is supported by a support arm provided on one side of the table and has a saw blade driven to rotate by a motor. The motor is respectively disposed behind the center of rotation of the table with respect to the base when regarded in a cutting direction in the miter saw mode and at a top dead center of the main body. -
EP 0 586 172 A2claim 1 discloses a pivoting power tool with a table. The table is pivotable about an axis with respect to a frame, which axis moves along an arc between two end positions which it assumes in the miter saw mode and the table saw mode, respectively. In the miter saw mode and at the top dead center of the main body, the motor which is provided on a support arm is positioned behind the center of rotation. - In order to overcome the above problems, an object of the present invention is to provide a flip over saw which prevents the table's accidental rotation while excellent operability in reversing the table is secured.
- In order to achieve the above object, a flip over saw comprising the features of
claim 1 is provided. Preferred embodiments are defined by the dependent claims. The present invention is characterized in that - the center of motor is located in front of the center of rotation of the table with the main body being at the top dead center in a miter saw mode in order to prevent the accidental rotation of the table more effectively.
- In addition, preferably the main body is pivotally mounted on a support arm via a support shaft rotatably in the upper and lower direction. Then, the distance between the center of rotation of the table and the center of motor is shorter than that between the center of rotation of the table and the center of the support shaft with the main body being at a bottom dead center in a miter saw mode in order to obtain excellent operability in reversing the table from the miter saw mode position to the table saw mode position.
- According to the present invention, since the table is well-balanced in the miter saw mode, the table is protected from being reversed even if locking of the table is released by malfunction. As a result, damage to the table and the main body caused by accidental reverse of the table can be prevented. In addition, since the center of gravity is positioned near the center of rotation, the table's reverse operation becomes easier, thereby improving operability.
- According to a preferred embodiment of the present invention, reversing of the table for conversion to the table saw mode is conducted by flipping up the front part of the table upwardly. By doing this, the center of gravity is positioned to the front, thereby preventing the accidental reverse of the table from the miter saw mode more effectively.
- According to the present invention, since the motor is closer to the center of rotation of the table the moment of inertia in reversing becomes small, so that reversing can be conducted easily with a light pressure. Therefore, an excellent operability can be achieved in reversing the table upon conversion from the miter saw mode to the table saw mode.

-
Fig. 1 is an overall view showing an example of a flip over saw andFig. 2 is a plain view thereof. A flip oversaw 1 has abase 2 which is a mounting in rectangular shape in a plain view and a table 3 placed on thebase 2, and asaw blade unit 4 mounted on the table 3. The table 3 is held rotatable 180 degrees around therotating shafts Figs. 1 and2 , the right is forward). Moreover, the table 3 can be secured in a horizontal state by astopper mechanism 6 even if either one or the other surface of table 3 faces upwardly. The table 3 also has acircular turntable 7 which is horizontally turnable, and aguide fence 8 parallel to the rotatingshaft 5 so as to transverse on theturntable 7. - The
saw blade unit 4 has asupport arm 9 standing at the rear part of theturntable 7 and amain body 11 held to be movable up and down by asupport shaft 10 at the upper end of thesupport arm 9. At the left side of ablade cover 12 which is a housing of themain body 11, amotor 13 and ahandle 14 are provided. In theblade cover 12, acircular saw blade 15 driven to rotate by themotor 13 is provided. Themain body 11 is urged toward the top dead center as shown inFig. 1 by a torsion spring (not shown) provided on thesupport shaft 10. As shown inFig. 3 , themain body 11 is lowered to the bottom dead center where it penetrates a slit (not shown) provided at the center of theturntable 7 when ahandle 14 is held down. Then a workpiece on theturntable 7 can be cut by the rotatingsaw blade 15. In this way, the flip over saw can be used as a miter saw. Thereference number 16 denotes a safety cover which is at the position of covering thesaw blade 15 when themain body 11 is at the top dead center and rotated to expose thesaw blade 15 in accordance with lowering of themain body 11. - The
support arm 9 can be tilted with themain body 11 in the right direction (the lower direction ofFig. 2 ) on theturntable 7. Fixing thetilted support arm 9 and themain body 11 by alever 17 at an arbitrary tilting position provides thesaw blade 15 with an angle in the perpendicular direction. With the tilt of themain body 11, bevel cutting can be conducted with respect to the workpiece on theturntable 7. Moreover, theturntable 7 can turn in a horizontal direction with themain body 11 when ahandle 14 is held down. In accordance with the selected angle of the horizontal turn of theturntable 7, orthogonal cutting and miter cutting can be conducted. In the orthogonal cutting, thesaw blade 15 is perpendicular to theguide fence 8. On the other hand, in the miter cutting thesaw blade 15 is horizontally slanted from the perpendicular position. - The
main body 11 can be secured at the bottom dead center as shown inFig. 3 by means of alocking mechanism 18 provided between thesupport arm 9 and themain body 11. As shown inFig. 4 , by reversing the table 3 with this secured condition of themain body 11, a table saw mode can be obtained wherein only thesaw blade 15 protrudes above the table 3 on which a workpiece is slid for cutting. In this table saw mode, therotating shaft 5 corresponds to the center of rotation of the table 3. Here, L1 is defined as the distance between the center of axle O of therotating shaft 5 and the center O1 of themotor 13, and L2 is defined as the distance between the center of axle O of therotating shaft 5 and thecenter 02 of thesupport shaft 10. Then, L1 is set to be shorter than L2. - In the miter saw mode, the rotating
shafts Figs. 1-3 (the miter saw mode) and at the second rotating position as shown inFig. 4 (the table saw mode). (The table 3 in the table saw mode is higher.) - Moreover, in order to allow the table 3 to rotate, an
opening 19 is provided at the center of thebase 2 in the longitudinal direction. In the inner lateral edges of thisopening 19, a pair offirst stopper rubbers opening 19. On the other hand, a pair ofsecond stopper rubbers opening 19. Thesecond stopper rubbers - With this configuration, the table 3 can be reversed only in the direction where the front part of the table is flipped up (the direction of an arrow in
Fig. 3 ) in converting from the miter saw mode to the table saw mode. On the other hand, the table 3 can be reversed only in the direction in which the rear part of the table is flipped up (the direction of an arrow ofFig. 4 ) in converting from the table saw mode to the miter saw mode. It should be noted that therotating shafts first stopper rubbers - As shown in
Fig. 5 , in this flip oversaw 1, amotor 13 is located adjacent to the upper side of therotating shafts main body 11 is positioned above the table. According to the invention, the motor's location adjacent to the upper side of therotating shafts motor 13 is located at the area slightly forward from the vertical surface S penetrating the center of axle O of therotating shafts - In the flip over saw configured as described above, in the miter saw mode the table 3 is secured by means of a
stopper mechanism 6 with thesaw blade unit 4 raised as shown inFigs. 1-3 . Then thehandle 14 is held to lower themain body 11 in which the blade saw 15 is rotating, so that a workpiece disposed on theturntable 7 can be cut, specifically, the bevel cutting by tilting themain body 11 and the miter cutting by horizontally turning theturntable 7 are achieved. - Here, because of the location of the
motor 13, the center of gravity of themain body 11 is substantially positioned at the center of the table 3 in the longitudinal direction (that is, adjacent to the rotating shaft 5). Therefore, the accidental reverse of the table 3 can be prevented even if thestopper mechanism 6 is released by malfunction and so on. - On the other hand, conversion into the table saw mode is conducted as follows. First, the
main body 11 is lowered to the bottom dead center to be secured by thelocking mechanism 18. Then thestopper mechanism 6 is released and the table 3 is turned 180 degrees in the direction where the front part of the table is flipped up until the table 3 is stopped at the reverse position abutting thesecond stopper rubbers first stopper rubbers motor 13 of themain body 11 locked at the bottom dead center is further closer to therotating shaft 5 in addition to above-described location. Consequently, the moment of inertia upon reversing becomes smaller, so that the reverse can be conducted easily with a light pressure. - Since the table 3 is well-balanced even in the miter saw mode, the table 3 is protected from reversing even if the
stopper mechanism 6 is released by malfunction. As a result, damage to the table 3 and themain body 11 caused by accidental reverse can be prevented. In addition, since the center of gravity is closer to the center of rotation, reverse operation of the table 3 becomes easier, thereby improving operability. - Moreover, when the
main body 11 is at the top dead center in the miter saw mode, the center of gravity is positioned forward since themotor 13's center O1 is positioned in front of the table 3's center of rotation O. As a result, the accidental reverse of the table 3 from the miter saw mode can be prevented more effectively. - On the other hand, when the
main body 11 is at the bottom dead center in the miter saw mode, the distance between the table 3's rotating center O and themotor 13's center O1 is shorter than that between the rotating center O and thesupport shaft 10'scenter 02. Consequently, the moment of inertia becomes small in reversing the table 3, so that reverse can be conducted easily with a light pressure. Therefore, an excellent operability can be achieved upon reverse of the table 3 to convert from the miter saw mode to the table saw mode. - Further, the structure of the flip over saw is not limited to the above embodiments. The main body capable of tilting to both sides may be applicable to the present invention, and on the contrary, the structure excluding bevel cutting or miter cutting may also be applicable.
