BEST MODE FOR CARRYING OUT THE INVENTION

  Embodiments of the present invention will be described below with reference to the drawings.

  1 to 13 are views showing an embodiment of a circular saw guide device according to the present invention.

  As shown in FIG. 1 to FIG. 13, a circular saw guide device 10 according to the present invention is a circular saw guide 5 to which a workpiece 1 such as a gypsum board, a plywood board, a panel or the like placed on a processing table (not shown) is mounted. When cutting by (see FIG. 12), the electric circular saw 5 is guided by being placed on the workpiece 1. That is, the electric circular saw 5 is guided by the circular saw guide device 10 placed on the workpiece 1 to cut the workpiece 1.

  As shown in FIGS. 1 and 2, the circular saw guide device 10 has an elongated guide plate 11 that guides the electric circular saw 5, and a grip that is connected to the side of the guide plate 11 by a mounting screw 12. Device 20.

  Among these, the guide plate 11 is placed on the workpiece 1 and has a guide side surface 11 a for guiding the electric circular saw 5.

  The grip device 20 includes a grip plate 21 placed on the workpiece 1 and an elongated grip body 23 supported on the grip plate 21 via a pair of support columns 24a and 24b. The body 23 extends from the distal end portion 23a toward the rear end portion (base end portion) 23b.

  By the way, if the grip body 23 is arranged close to the guide plate 11 in order to reduce the size of the grip plate 21 and reduce the size, the motor portion of the electric circular saw 5 comes into contact with the grip body 23 during the cutting operation. There is a risk. If the grip body 23 is arranged in parallel with the guide plate 11, a burden is imposed on the angle of the operator's arm, and a comfortable work cannot be performed. For this reason, the grip body 23 is provided on the grip plate 21 at a certain distance from the guide plate 11 with a certain angle with respect to the guide plate 11.

  Further, an abutting body 30 is provided on the bottom surface of the grip plate 21 by a fastener 33 such as a rivet (see FIG. 11). The abutting body 30 extends perpendicularly to the elongated guide plate 11 and contacts the side edge 1 a of the workpiece 1 to position the circular saw guide device 10.

  Next, the guide plate 11 will be described in detail with reference to FIGS. 1, 2, and 6A and 6B. As shown in FIGS. 1, 2, and 6 (a) and 6 (b), the guide plate 11 is connected to the grip plate 21 of the grip device 20 by a mounting screw 12. Such a guide plate 11 has a guide side surface 11 a for guiding the electric circular saw 5 as described above, and is formed of a hollow body including a pair of internal spaces 19.

  Among these, the inner space 19 on the guide side surface 11a side has a rectangular cross section, and the guide side surface 11a is a pair of round bars having a circular cross section that contact the electric circular saw 5 and guide the electric circular saw 5 by line contact. 13 are provided side by side in the vertical direction (see FIG. 6B). As shown in FIG. 6B, each round bar 13 is embedded inside the surface 17 of the guide side surface 11 a of the guide plate 11 and extends in the horizontal direction along the longitudinal direction of the guide plate 11. In this case, the axis of each round bar 13 is located inside the surface 17 of the guide side surface 11a. For this reason, although each round bar 13 protrudes outward from the surface 17 of the guide side surface 11a, each round bar 13 can be fixed to the guide side surface 11a safely and reliably.

  That is, it is conceivable to fix the round bar 13 to the surface 17 of the guide side surface 11a of the guide plate 11 with an adhesive or the like. However, when the round bar 13 is fixed to the surface 17 of the guide side surface 11a with an adhesive, It is also conceivable that the round bar 13 falls off from the guide side surface 11a. It is also assumed that a simple cutting operation is performed using a cutter such as a cutter knife instead of the electric circular saw 5, but when fixed with an adhesive, the gap between the guide side surface 11a and the round bar 13 during the operation is assumed. It is also assumed that the blade is accidentally inserted and peeled off.

  However, according to the present invention, each round bar 13 is embedded in the guide side surface 11a, and the shaft core of the round bar 13 is located inside the surface of the guide side surface 11a. It can be securely and securely fixed.

  The number of round bars 13 may be one or plural. Instead of the round bar 13, a bar 13a having a triangular cross section or a bar 13b having a square cross section may be used (FIG. 6C). Further, instead of the round bar 13, a bar 13c having a flat cross section may be provided on the guide side surface 11a. Any one of these triangular bars 13a, square bars 13b, or flat bars 13c may be provided, or a plurality of bars 13c may be provided.

  As described above, the guide plate 11 is formed of a hollow body having a pair of internal spaces 19 and 19, and end caps 16 and 16 are provided at both ends of the guide plate 11. 11 internal spaces 19, 19 are sealed.

  In addition, as the material of the guide plate 11 made of a hollow body, generally, an extruded aluminum material that is continuously formed is employed. If the guide plate 11 is cut into a necessary length, its sharp end face is used. Therefore, the hose portion of the dust collector provided on the circular saw may get caught or damaged. The end caps 16 and 16 can also be expected to prevent this.

  By providing the pair of round bars 13 for guiding the electric circular saw 5 by line contact on the guide side surface 11a of the guide plate 11 as described above, the guide plate 11 can be compared with the case of guiding the electric circular saw 5 by surface contact. The frictional resistance applied from the guide plate 11 to the electric circular saw 5 side when the electric circular saw 5 is moved along can be reduced. For this reason, the workability | operativity at the time of cutting work using the electric circular saw 5 can be aimed at.

  In general, the electric circular saw 5 is heavy and moves along the guide plate 11 while being placed on the workpiece 1, so that the electric circular saw 5 does not tilt laterally during movement. For this reason, one round bar 13 may be provided on the guide side surface 11 a of the guide plate 11, and the electric circular saw 5 may be guided by point contact with the round bar 13.

  Next, the grip device 20 will be described in detail with reference to FIGS. 1, 2, 7A and 7B, and FIGS. 8A and 8B. As shown in FIGS. 1, 2, 7 (a) and 7 (b) and 8 (a) and 8 (b), the grip device 20 includes a grip plate 21 placed on the workpiece 1, and a grip plate. 21 has an elongated grip body 23 supported by a pair of support columns 24a and 24b. The grip plate 21 is provided with three openings 21a, and a butt confirmation window 22 is provided on the rear end side (base end side).

  Further, the grip body 23 has a front end portion 23a that protrudes further to the front end side than the support column 24a on the front end side, a rear end portion 23b that protrudes further to the rear end side from the support column 24b on the rear end side (base end side), And a central portion 23c between 24a and 24b.

  The grip body 23 may protrude only to the rear end side of the support column 24b without protruding from the support column 24a to the front end side, or only to the front end side of the support column 24a without protruding from the support column 24b to the rear end side. It may protrude.

  Further, as shown in FIGS. 7A, 7B and 8A, 8B, of the pair of support columns 24a, 24b that support the grip body 23, the support column 24a on the front end side is more than the support column 24a on the rear end side. The height is high. For this reason, the grip body 23 is arrange | positioned so that it may rise toward the front-end | tip part 23a from the rear-end part 23b.

  Further, the grip body 23 is formed of a hollow body having a pair of cylindrical inner spaces 25 arranged in the lateral direction, and the surface 28 is roughened so that the grip body can be gripped easily and reliably. Can do.

  Since the grip body 23 is arranged so as to rise from the rear end portion 23b toward the front end portion 23a as described above, an operator who cuts the workpiece 1 using the electric circular saw 5 is There is no need to tilt and grip the grip body 23, and the electric circular saw 5 can be moved along the circular saw guide device 10 while gripping the grip body 23 in a stable posture.

  Further, since the grip body 23 has a front end portion 23a protruding from the support post 24a to the front end side and a rear end portion 23b protruding from the support post 24b to the rear end side, the operator can remove the central portion 23c between the support posts 24a and 24b. In addition to gripping, it is possible to grip the front end portion 23a or the rear end portion 23b of the grip body 23.

  As shown in FIGS. 14A to 14E, the grip body 23 may be bent in the left-right direction when viewed from the top surface at the positions of the support posts 24a and 24b (FIG. 14A). It may be bent at the positions of 24a and 24b in the vertical direction to form an angle (FIG. 14 (b)).

  Further, the shape of the front end portion 23a or the rear end portion 23b of the grip body 23 may be inflated in a spherical shape (FIG. 14C), and the grip body 23 is bent by bending the tip of a straight line extending beyond the column 24a or 24b. The whole may be L-shaped (FIG. 14D), and the grip body 23 may be T-shaped as a whole (FIG. 14E).

  Further, the shape of the central portion 23c of the grip body 23 is not limited to a linear shape, but may be a bow warp shape or a reverse warp shape.

  Moreover, as shown to Fig.8 (a) (b), the recessed part 27 is formed in the bottom face of the part corresponding to the support | pillars 24a and 24b among the grip boards 21 of the grip apparatus 20, respectively. An attachment screw 26 is inserted from the concave portion 27 side of the grip plate 21, and the columns 24 a and 24 b are fixed to the grip plate 21 by the attachment screw 26. The mounting screw 26 extends through the grip plate 21 to the columns 24a and 24b. Further, the head 26 a of the mounting screw 26 stops in the concave portion 27 of the grip plate 21, and covers the head 26 a of the mounting screw 26 in this concave portion 27, thereby providing a slip prevention function with the workpiece 1. A rubber plate 25 is inserted.

  As described above, the concave portion 27 is provided on the bottom surface of the grip plate 21 corresponding to the columns 24 a and 24 b, the mounting screw 26 is inserted into the concave portion 27, and the rubber plate 25 is fitted into the concave portion 27. It is rare. For this reason, when the operator who cuts the workpiece 1 using the electric circular saw 5 holds the grip body 23 of the grip device 20 and presses it downward, the pressing force from the operator is applied from the grip body 23 to each column. It is transmitted directly to the rubber plate 25 via 24a, 24b and the grip plate 21. For this reason, a large pressing force can be applied from the rubber plate 25 to the workpiece 1, and the frictional force between the rubber plate 25 and the workpiece 1 is increased, so that the workpiece 1 and the grip plate 21 are A high anti-slip function can be exhibited.

  If the rubber plate 25 is extremely thick, when the guide plate 11 is placed on the workpiece 1, there is a risk that it may become unstable as a result of causing a glitch.

  Therefore, the thickness of the rubber plate 25 provided in the concave portion 27 is ideally set to a minimum thickness that can provide an anti-slip effect.

  Moreover, the shape of the rubber plate 25 and the recessed part 27 is not limited to a round shape. Further, a portion of the rubber plate 25 that corresponds to the head portion 26a of the mounting screw 26 may be cut out to make the rubber plate 25 into a donut shape. In this case, if the attachment screw 26 of the grip body 23 is loosened, the attachment screw 26 can be tightened.

  Although the circular saw guide device 10 having a high anti-slip effect has been proposed with the above configuration, when it is desired to shift the position on the work piece, the anti-slip is too effective to prevent slipping and smooth operation can be performed. There may be a case in which there is no mark or a mark remains on the workpiece 1 side due to rubbing of the rubber plate 25 or the like.

  Therefore, although not shown in the drawings, if a plate spring is provided at several locations below the grip plate 21 of the circular saw guide device 10 to slightly lift the grip plate 21 and a force is applied from above with the grip body 23, the plate spring loses. The rubber plate 25 that sinks and is non-slip comes into contact with the workpiece 1 and exhibits an effect of preventing deviation. Further, a part of the grip plate 21 may be punched out so that the tongue side is erected to have a function of a leaf spring.

  Next, the abutting body 30 provided on the bottom surface of the grip plate 21 will be described.

  As shown in FIGS. 1, 2, 10, and 11, the abutting body 30 is attached to the bottom surface of the grip plate 21 by a rivet 33, and the abutting body 30 is against the elongated guide plate 11. It extends orthogonally (with respect to the guide direction of the guide plate 11). As shown in FIG. 11, the abutting body 30 is formed of a hollow body having a rectangular cross section including an upper plate 30a provided with a groove for burying the head of the rivet 33, a lower plate 30b, and a pair of side plates 30c. ing.

  Then, one side plate 30 c of the abutting body 30 abuts on the side edge 1 a of the workpiece 1 to position the circular saw guide device 30. The upper plate 30 a of the abutting body 30 is in contact with the bottom surface of the grip plate 21, and the upper plate 30 a passes through the upper plate 30 a of the abutting body 30 in the abutting body 30. A rivet 33 that is fixed to the bottom surface is disposed (FIG. 11).

  In FIG. 11, the head of the rivet 33 is located in the abutting body 30. Further, a discard tree 15 described later is provided in the abutment body 30 so as to be slidable along the abutment body 30, and the discard tree 15 is disposed in the other side plate 30 c of the abutment body 30 in the abutment body 30. A fixing screw 32 for fixing is provided.

  As shown in FIG. 11, the abutting body 30 is brought into contact with the bottom surface of the grip plate 21 via the upper plate 30 a, and the upper surface 30 a is fixed to the bottom surface of the grip plate 21 by the rivets 33 provided in the abutting body 30. By doing so, the abutting body 30 can be directly fixed to the bottom surface of the grip plate 21. Therefore, for example, the abutting body 30 is provided with a mounting flange that expands to the side, and the abutting body 30 is securely attached to the bottom surface of the grip plate 21 via the mounting flange. The abutting body 30 is not deformed during the operation.

  Instead of fixing the abutting body 30 to the bottom surface of the grip plate 21 with the rivets 33, the abutting body 30 may be fixed to the bottom surface of the grip plate 21 by screwing, welding, claw fastening, adhesion, or the like.

  The abutting body 30 and the discarded tree 15 can be provided separately. That is, by installing two hollow bodies having a rectangular cross section in parallel, one of them can function as a butting body 30 and the other as a holding body for the abandoned tree 15 at a distant position. Moreover, it becomes possible to comprise the butting body 30 with a solid square material with higher strength by making the holding body of the discarded wood 15 that must be hollow separately. Furthermore, it is not always necessary to provide the solid wood 15 as the abutting body 30 and provide the holding body for the waste wood 15 for the user who does not use the waste wood 15.

  Also, some workpieces may not have a simple rectangular cross section, like siding materials. In such a case, if the thickness of the abutting body 30 is small, it may happen that the abutting body 30 does not contact the end surface of the workpiece 1 accurately. Therefore, assuming that the cross section of the workpiece 1 is complicated, the thickness of the abutting body 30 may be larger than that of the workpiece 1.

  Incidentally, the thickness of the abutting body 30 is smaller than the thickness of the workpiece 1. Therefore, even when a plurality of workpieces 1 are stacked and a cutting operation is performed on the uppermost workpiece 1 using the circular saw guide 10, the abutting body 30 is only the uppermost workpiece 1. The circular saw guide 10 can be positioned by abutting against. Thereby, it is possible to prevent the abutting body 30 from coming into contact with the workpiece 1 below the uppermost workpiece 1 and inaccurately positioning the circular saw guide 10.

  By the way, as shown in FIGS. 12 and 13, a temporary placement plate 35 is provided at the rear end portion of the guide plate 11 so as to protrude the guide side surface 11 a and temporarily place the electric circular saw 5. The temporary placing plate 35 is provided at the rear end portion of the guide plate 11 so as to protrude sideways. The temporary placement plate 35 can be fixed to the guide plate 11 by the fixing screw 36 after the temporary placement plate 35 is protruded from the rear end portion of the guide plate 11 by a desired length.

  In this way, the temporary placement plate 35 is provided at the rear end portion of the guide plate 11, and the electric circular saw 5 is temporarily placed on the temporary placement plate 35, so that the cutting position is carefully determined as in the case of cutting the finishing material. When it is necessary to do so, the electric circular saw 5 can be easily positioned with respect to the guide plate 11 while gazing at the cutting edge.

  Further, when careful positioning is not required, such as during rough cutting, the temporary placing plate 35 is not necessary and can be removed together with the fixing screw 36.

  Further, on the grip plate 20 of the grip device 20, a cutting mark 29 indicating the end of the cutting lengths A and B from the abutment body 30 toward the guide direction of the guide plate 11 is provided.

  Next, the operation of the present embodiment having such a configuration will be described.

  First, as shown in FIG. 3, the workpiece 1 is placed on the machining table, and then the circular saw guide device 10 is placed on the workpiece 1.

  Next, the side plate 30 c of the abutting body 30 provided on the bottom surface of the grip plate 21 comes into contact with the side edge 1 a of the workpiece 1, and the circular saw guide device 10 is positioned on the workpiece 1.

  In this case, the inclination between the abutting body 30 and the workpiece 1 can be confirmed through the matching confirmation window 22 provided on the grip plate 21. Thereby, it can be confirmed whether the side surface 30c of the abutting body 30 is correctly in contact with the side edge 1a of the workpiece 1 and the circular saw guide 10 is correctly positioned.

  In this case, as shown in FIG. 4, the discard tree 15 is drawn out from the abutting body 30 in advance, and the discard tree 15 is fixed in the abutting body 30 by the fixing screw 32. As shown in FIG. 13, the temporary placement plate 35 is pulled out by a desired length from the rear end portion of the guide plate 11, and the temporary placement plate 35 is fixed to the guide plate 11 by a fixing screw 36.

  Next, as shown in FIG. 5A, the electric circular saw 5 is placed on the temporary placing plate 35 provided on the guide plate 11, and the electric circular saw 5 moves along the guide side surface 11 a of the guide plate 11. Then, the discarded wood 15 and the workpiece 1 are cut by the electric circular saw 5. Thus, since the electric circular saw 5 is first placed on the temporary placing plate 35 and then moves along the guide side surface 11a of the guide plate 11, the electric circular saw 5 is correctly positioned with respect to the guide plate 11. Thereafter, the electric circular saw 5 can be moved along the guide side surface 11a of the guide plate 11 while accurately guiding it.

  The first cutting edge of the workpiece 1 can be determined by cutting the discarded tree 15 and the workpiece 1 with the electric circular saw 5. Further, the protruding length of the discarded wood 15 corresponds to the length between the guide side surface 11 a of the guide plate 11 and the cutting blade of the electric circular saw 5. For this reason, in the next process, the circular saw guide device 10 is correctly positioned on the workpiece 1 by aligning the tip of the discarded tree 15 of the circular saw guide device 10 with the marking line 2 of the workpiece 1. (FIG. 5B).

  Next, as shown in FIG. 5B, the electric circular saw 5 is placed on the temporary placement plate 35 of the circular saw guide device 10 as in the previous case, and the electric circular saw is moved along the guide side surface 11 a of the guide plate 11. 5 is moved. In this way, the workpiece 1 can be accurately cut along the marking line 2 by the electric circular saw 5.

  During this time, the operator holds the grip body 23 of the grip device 20 and applies a pressing force to the grip plate 21.

  In this case, as described above, the grip body 23 is disposed so as to rise from the rear end portion 23b toward the front end portion 23a. Therefore, an operator who uses the electric circular saw 5 to cut the workpiece 1 The electric circular saw 5 can be moved along the circular saw guide device 10 while holding the grip body 23 in a stable posture without having to grip the grip body 23 by tilting forward.

  A concave portion 27 is provided on the bottom surface of the grip plate 21 corresponding to the columns 24a and 24b. A mounting screw 26 is inserted into the concave portion 27, and a rubber plate 25 is fitted into the concave portion 27. Yes.
