Description

[0001] The present invention relates generally to a hand-held cutting device, for example a cutting device referred to as a portable circular saw.

[0002] This type of cutting device consists of a base that rests (places) on the upper surface of the material to be cut, and a main body of the cutting device that is mounted on the upper side of the base. The main body of the cutting device contains a circular cutting blade (saw blade) that rotates using an electric motor as a drive source. A lower portion of the cutting blade protrudes from the lower surface of the base. Cutting (sawing) is performed by the lower portion of the cutting blade, which protrudes from the lower surface of the base, cutting (sawing) into the material to be cut.

[0003] The main body of the cutting device is mounted so that it can be tilted in a direction in which the upper part of the main body is shifted primarily to the right with respect to the cutting direction (the direction in which cutting (sawing) is performed). When the main body of the cutting device is held in a vertical cutting position, in which the main body of the cutting machine is not tilted with respect to the base, a vertical cut can be performed such that the cutting blade cuts into the material to be cut at a right angle. If the main body of the cutting device is tilted and the cutting blade cuts into the material to be cut at an angle, a so-called bevel cut is performed.A commonly used tilt angle of the cutting device main body, such as a 45° bevel cutting position or a 50° bevel cutting position, can be quickly and accurately positioned (set) by a stop mechanism (a positive stop mechanism). Prior art relating to the stop mechanism described above is disclosed, for example, in Japanese patent application no. 2001-54816 A, Japanese patent application no. 2001-232515 A, and Japanese patent application no. 2007-7883 A.

[0004] Furthermore, this type of cutting device incorporates a cutting depth adjustment mechanism. This mechanism allows the main body of the cutting device to be tilted (pivoted) up and down relative to the base, thereby adjusting the cutting depth relative to the material being cut by increasing or decreasing the amount by which the cutting blade protrudes from a lower surface of the base. The cutting depth adjustment mechanism is configured in such a way that a front portion of the main body of the cutting device is tilted up and down relative to the base, and a guide element, referred to as the depth guide, is positioned between a rear portion of the main body of the cutting device and the base.By changing the position in which the main body of the cutting device is coupled to the depth guide, which is arranged so that it faces upwards on the upper surface of the base, the tilt position and / or depth position of the main body of the cutting device relative to the base can be changed, and the cutting depth can be adjusted. Prior art relating to the cutting depth adjustment mechanism described above is disclosed, for example, in Japanese patent application no. 2006-1148 A and Japanese patent application no. 2009-248326 A.

[0005] As described above, the disclosures relate to the stop mechanism for bevel cuts and the cutting depth adjustment mechanism. Regarding the latter, the cutting depth adjustment mechanism, the main body of the cutting device is configured for easy positioning using a so-called detent mechanism, which provides a perceived click at predetermined cutting depth positions. However, a user must move the main body of the cutting device slowly up and down while visually verifying the desired cutting depth position. This is because, if the main body of the cutting device is moved quickly up and down, it will pass through the detent mechanism at the desired cutting depth position. In this respect, usability requires improvement.Therefore, there is a need to improve the operability of a cutting depth adjustment mechanism by quickly and easily positioning a target cutting depth position, in order to improve the operability and / or usability of the cutting device.

[0006] The present teachings relate generally to a cutting device that may include a base contacting an upper surface of a material to be cut, and a cutting device main body mounted above an upper surface of the base. The cutting device main body may include a circular rotating cutting blade driven by an electric motor, and the cutting device may perform a cutting (sawing) operation such that a lower portion of the rotating cutting blade, projecting from a lower surface of the base, cuts into the material to be cut. Furthermore, the cutting device main body may be mounted to pivot upwards and downwards relative to the base.A cutting depth adjustment mechanism may be provided, allowing the cutting depth of the rotating cutting blade to be adjusted (set) relative to the material being cut by changing the projection of the rotating cutting blade from the side of the lower surface of the base. The cutting depth adjustment mechanism may include a cutting depth stop mechanism, which allows the end position of an upward movement of the cutting device main body in an up-down direction to be adjusted.

[0007] The configuration described above allows the end position of the upward movement of the cutting device main body to be changed by the cutting depth stop mechanism. Accordingly, once the cutting depth is adjusted, a target cutting depth can be quickly achieved, thus improving reproducibility (repeatability) with respect to the cutting depth. As described above, fast and reliable positioning is difficult with a prior art cutting depth mechanism that uses a so-called detent mechanism. However, according to the configuration described above, movement of the cutting device main body to the end position of the upward movement is only necessary when adjusting a cutting depth, provided that the end position of the upward movement of the cutting device main body is appropriately defined by the cutting depth stop mechanism.This allows for quick and reliable positioning of the target cutting depth. In this respect, the ease of use of the cutting device and the cutting depth adjustment mechanism can be improved.

[0008] In one embodiment, the cutting depth adjustment mechanism may include a depth guide located on the upper surface of the base. The depth guide may extend upward from the upper surface of the base between a blade housing for covering the upper part of the rotating blade and a user-held handle. The cutting depth of the rotating blade can be set (adjusted) as desired by fixing the main body of the cutting device to the depth guide. Furthermore, the cutting depth stop mechanism may include a stop lever located on the side of the depth guide opposite the blade housing.

[0009] The configuration described above allows the stop lever of the cutting depth stop mechanism to be positioned between the depth guide and the cutting blade housing, and away from the handle in the base width direction, perpendicular to the cutting direction. Consequently, the stop lever does not interfere with handle operation, ensuring excellent usability of the cutting device.

[0010] In one embodiment, the cutting depth stop mechanism can include a stop component that can move along a guide groove in the depth guide. Furthermore, the stop component can be fixed by holding the depth guide from both sides in a thickness direction and by tightening it with the stop lever. Additionally, a variable-width element, in which the thickness of the depth guide changes, can be provided in the depth guide.

[0011] With the configuration described above, if the stop lever is locked relative to the outer circumferential edge of the depth guide, which is curved in an arc shape, a tip of the stop lever can be prevented from pointing upwards towards an upper side of the depth guide, since an angle of the stop lever relative to an outer circumferential edge of the depth guide is changed.

[0012] In one embodiment, the depth guide can include a regulating component for controlling an area in which the stop lever of the cutting depth stop mechanism can be actuated.

[0013] The configuration described above prevents the stop lever from being overtightened and / or over-loosened. Therefore, the operability of the cutting depth stop mechanism can be improved.

[0014] In one embodiment, the stop lever can include a main lever part and a secondary lever part.

[0015] The configuration described above allows a tilting operation to be performed with a fingertip placed on one or both of the main lever parts and the secondary lever parts. This can improve the usability of the stop lever.

Accordingly, the tilting position of the cutting device main body can be seen. 10 can be done in a simple way.

[0062] The cutting depth adjustment mechanism is described below. 40 described. In a top view, the cutting depth adjustment mechanism can be seen. 40 between the handle 14 and the cutting blade housing 13 be arranged. As described above, the cutting depth adjustment mechanism can be 40 the depth guide 41 exhibiting a circular arc shape. As in Fig. 13 and Fig. As shown in Figure 14, a cylindrical bearing attachment part can be used.41c on the lower part of the depth guide 41 be arranged. The depth guide 41 can be positioned so that it extends forwards and backwards in relation to the main body support bracket 25 on the rear side by means of a spindle 42 , which are used in the storage approach 41c Once inserted, it can tilt. The spindle 42 can be perpendicular to the main body tilting spindle 18 be.

[0063] The spindle 42 can be used in the storage attachment part 41c depth control 41 be inserted so that the spindle 42 It can be moved in the axial direction and rotated around its axis. Due to this design, the depth control can be adjusted. 41 through the main body support bracket 25 be mounted in such a way that the depth guide is positioned in the axial direction of the spindle. 42 (in one latitude direction of the base) 2, which is a direction indicated by an unfilled arrow in Fig. (as shown in section 14) can be adjusted. By adjusting the position of the depth guide. 41 in the base width direction in relation to the main body support bracket 25 can be of an extent to which the rotating cutting blade 12 parallel to the end face of the base 2 It needs to be precisely adjusted. A position of the depth guide 41 In the base width direction, adjustment can be made by tightening a screw (not shown) located in the lower surface of the bearing attachment part. 41c is arranged, and by pressing the spindle 42 be fixed.

[0064] The depth guide 41 can be configured to extend in an arc shape in an upward and diagonally forward direction from the main body support bar 25 extends. The depth guide 41can essentially run parallel to the back (the left side in) Fig. 4) of the cutting blade housing 13 be arranged. A thickness and / or a width dimension in the base width direction of the depth guide. 41 It can be configured so that it is not constant. The depth guide 41 It can be configured to be in a tapered shape, so that a thickness of the depth guide 41 becomes thicker towards a lower end part.

[0065] As in Fig. 12 to Fig. 14 shows a guide slot hole 41a in the depth control 41 The guide groove should be provided. 41a can move from the lower part to the upper part of the depth guide 41 be arranged, that is to say, essentially along the entire length of the depth guide 41 The guide slot 41acan be configured to operate in the same way as the depth guide 41 , is curved in an arc shape. Furthermore, the guide groove hole 41a through the depth guidance 41 in the thickness direction of the depth control 41 be trained through it. As in Fig. 13 and Fig. As shown in Figure 14, a wider stepped section is possible. 41b on the back side of the guide slot 41a be trained.

[0066] A fixed shaft 44 , which extends from the back (the left side in Fig. 4) of the cutting blade housing 13 extends, can into the guide slot 41a depth control 41 It must be inserted. The fixed shaft 44 can be attached to the back of the leaf casing 13 be fixed in such a way that the fixed shaft 44It cannot rotate or move axially. A screw shaft portion can be attached to a tip portion of the fixed shaft. 44 A depth-locking lever is provided. 43 can be done at the tip of the fixed shaft 44 It can be attached using this screw shaft part. By tilting the depth locking lever. 43 in one locking direction (a direction to the right when viewed from the back), the depth guide 41 firmly between the depth locking lever 43 and the cutting blade housing 13 be held and the main body of the cutting device 10 It can be fixed with respect to the up-down tilt direction. In this way, the cutting depth of the rotating cutting blade can be adjusted. 12 be fixed. On the other hand, it can be fixed by tilting the depth locking lever. 43in an unlocking direction (a direction to the left when viewed from the rear) a holding dimension and / or a tightening dimension of the depth guide 41 between the depth locking lever 43 and the cutting blade housing 13 be released and the main body of the cutting device 10 can be around the up-down tilt spindle 22 It can be tilted upwards and downwards in one direction. In this way, the cutting depth of the rotating cutting blade can be adjusted. 12 be adjusted.

[0067] Fig. 12 and Fig. Figure 13 shows a state in which the cutting depth is at its maximum, so that the main body of the cutting device 10 is positioned at a movable lower end. In this state, the fixed shaft can 44 in the vicinity of the lower end part of the guide groove 41a , as in Fig. 13 shown, be positioned. When the depth locking lever43 is tilted in the unlocking direction from this position and the main body of the cutting device 10 upwards around the up-down tilt spindle 22 If tilted, the depth locking lever can 43 and the fixed shaft 44 in one direction upwards along the guide groove 41a depth control 41 integral with the cutting device main body 10 be shifted. The cutting depth of the rotating cutting blade. 12 can within the area in which the fixed shaft 44 along the guide groove 41a It can be moved or adjusted.

[0068] In this embodiment, a position of a substantially upper end part of the guide groove hole can be determined. 41a (an upper end position within the area in which the fixed shaft 44 (can be shifted) by a cutting depth stop mechanism50 The cutting depth stop mechanism can be changed and / or adjusted. 50 can be used in the depth control 41 be planned. As in Fig. As shown in 14, the cutting depth stop mechanism can be 50 a stop component 51 and a stop lever 52 included, which contains the stop component 51 fixed in position. Furthermore, the stop component can 51 a sliding part 51a and a contact part 51b included. The contact part 51b can be integral with the sliding part 51a on the front surface of the sliding part 51a be trained. The contact part 51b can be accessed from the rear end of the sliding part 51a protrudes further back. A screw hole 51c can be found on the front side of the sliding part 51a be provided. The stop component 51 can be arranged in such a way that the sliding part 51aalong the inside of the stepped section 41b can slide. Furthermore, the stop component can 51 through the guide slot 41a be stored in such a way that the contact part 51b in the guide groove 41a can be positioned.

[0069] The stop lever 52 can a main lever part 52a and an auxiliary lever part 52b included. The main lever part 52a and the auxiliary lever part 52b can extend in such a way that the two parts 52a and 52b They are essentially configured in a V-shape and extend in different directions. The user can adjust the stop lever. 52 with its fingertip placed on one or both of the main lever part 52a and the auxiliary lever part 52b incline. A fixing screw 53 can be connected to a coupling hole 52cof the stop lever 52 be coupled so that the fixing screw 53 It cannot be rotated relatively. The fixing screw 53 can be achieved through a retaining ring 54 be prevented from removing it from the stop lever 52 falls out. The fixing screw 53 can be inserted into the guide slot from the front surface 41a depth control 51 by means of a washer 55 It must be inserted. The fixing screw 53 can go into the screw hole 51c of the stop component 51 be screwed together.

[0070] If the stop lever 52 If the screw is tilted in the direction of the screw (in the direction of a locking side), the fixing screw can 53 in the screw hole 51c be tightened and the stop component 51 can be positioned in any position along the guide slot 41abe fixed. If the fixing screw 53 in the screw hole 51c Once tightened, the guide groove hole 41a depth control 41 through the sliding part 51a of the stop component 51 and the washer 55 , i.e., held firmly from both sides and the stop component 51 can be positioned in any position of the guide slot 41a be fixed. If the stop lever 52 If the screw is tilted in a loosening direction (towards a release side), a tightening extent of the fixing screw can be determined. 53 in the screw hole 51c of the stop component 51 be released and the stop component 51 can be done along the guide groove 41a to be moved.

[0071] A position of the contact part 51b can be achieved by moving the stop component 51 along the guide groove 41aThe contact part needs to be adjusted. 51b can have a significant function of changing an upper end part of the guide groove hole 41a . If the cutting device main body 10 To achieve a smaller cutting depth than the maximum cutting depth, and / or to tilt upwards, the contact part can be fixed. 51b at a constant position and by touching the fixed shaft 44 of the depth locking lever 43 with the contact part 51b The tilt position of the cutting device's main body, both upwards and downwards, can be quickly and accurately restored. Accordingly, a constant cutting depth can be quickly and accurately restored (reproduced).

[0072] As described above, the stop component 51 the essential function of changing the upper end part of the guide groove hole 41aexhibit this. Thus, the cutting depth stop mechanism can 50 The function includes regulating a lower limit of the adjustable cutting depth. Furthermore, if the cutting depth is set to a maximum, as in Fig. As shown in 13, this can be achieved by moving the stop component. 51 into the lowest position and by touching the fixed shaft with the stop component 51 an unexpected displacement of the cutting device main body 10 upward movement is prevented and the maximum cutting depth can be maintained even if the depth lock lever is engaged. 43 is solved by an error (mistakenly).

[0073] As in Fig. As shown in 14, a regulatory edge part can be 45 on the lower surface of the depth guide 41 be provided for. The regulatory edge section 45 can be located below the main lever part 52 and the auxiliary lever part 52bbe arranged so that it faces towards the front surface (to the right) Fig. 14) along a lower side of the guide slot 41a The regulatory edge section is located at the front. 45 Can the stop lever be actuated? 52 to restrict to a predetermined area. If the stop lever 52 When tilted towards the unlocking side, the auxiliary lever part 52b with the regulating edge part 45 interfere and a tilting actuation of the stop lever 52 The screw loosening direction may be limited. On the other hand, if the stop lever 52 When tilted towards the locking side, the main lever part 52a with the regulating edge part 45 interfere and a tilting actuation of the stop lever 52 The tightening direction of the screws may be restricted. In this way, the regulating edge part can 45 the stop lever 52to prevent it from being excessively tightened and loosened, thus preventing the position of the stop component from being affected. 51 by rapidly tilting (swiveling) the stop lever 52 It can only be changed by a necessary and sufficient angle. Accordingly, the operability of the cutting depth stop mechanism can be affected. 50 It should be improved.

[0074] As described above, the thickness of the depth guide can be adjusted. 51 (thickness d, as in Fig. (shown in 14) is modified (modified part) instead of remaining constant. In this embodiment, the thickness of the depth guide is changed. 51 It becomes thicker towards the lower end. Because of this design, by changing the angle (mainly) of the main lever part... 51 of the stop lever 52 with respect to an outer circumferential edge of the depth guide 41 , which has an arc shape, a tip of (mainly) the main lever part 52not upwards towards the side of the upper part of the depth guide 41 be judged.

[0075] Furthermore, a position and / or direction of (mainly) the main lever part can be determined. 52 with regard to the outer circumferential edge of the depth guide 41 in an unlocked position in which the stop lever 52 is solved, on one side of the upper part and one side of the lower part of the depth guide 41 can be changed. In this embodiment, since the thickness d is on the lower side of the depth guide, 41 It is configured to be large (thicker), one direction of the main lever part 52a , in which the stop lever 52 located on the lower side and inclined in the unlocking position, rather obliquely (a direction in which the main lever part 52 (might be more loose) than upwards (directed), in case a direction of the main lever part52 , in which the stop lever 52a located on the higher side and inclined in the locking position, is pointing upwards (upwards). Because of this, a direction and / or a relative position of the main lever part can be determined. 52 in relation to the outer circumferential edge of the depth guide 41 , which has a curved shape, with, for example, a radial direction of depth control 41 agree, even if the main lever part 52a is positioned on the top side or on the bottom side.

[0076] Furthermore, the depth control 41 the regulatory edge part 45 Included. The regulating edge part. 45 can the stop lever 52 to prevent it from being excessively loosened, since the secondary lever part 52 with the regulating edge part 45 interferes. A relative position of the main lever part 52a and the auxiliary lever part 52bcan be configured so that the main lever part 52a in the radial direction with respect to the outer circumferential edge of the depth guide 51 in which case the auxiliary lever part is positioned 52b the regulatory edge part 45 touched from above. In this way, since the auxiliary lever part 52b with the regulating edge part 45 If interfered, the release position of the stop lever may be affected. 52 can be regulated, and accordingly the main lever part can be adjusted. 52a in the radial direction with respect to the outer circumferential edge of the depth guide 41 can be positioned at any time.

[0077] Furthermore, as described above, the depth control 41 It must be configured to have a tapered shape, so that a thickness d of the depth guide 41It becomes thicker towards a lower end. This design allows for a release position of the stop lever. 52 be configured so that the main lever part 52a in the radial direction with respect to the outer circumferential edge of the depth guide 41 is positioned even if the main lever part 52a on the top or bottom side of the depth guide 41 is located. Accordingly, a subsequent fingertip operation can tilt the main lever part. 52a in one locking direction in a simple way, even if the stop lever 52 on the side of the upper position or the side of the lower position of the depth guide 41 is located. In this respect, the operability of the stop lever can be improved. 52 It should be improved.

[0078] Furthermore, as in Fig. 2 and Fig. As shown in 14, a depth scale can be used. 41d, which are used to check (observe) the cutting depth of the rotating cutting blade 12 (a forward measurement from the lower surface of the base 2 ) is used on the upper surface of the depth guide 41 It should be marked. The depth scale 41d The cutting depth can be marked "0", "15", "30", "45", and "60" in sequence from top to bottom, with a cutting depth interval of 15 mm. If the fixed shaft... 44 When positioned at “0”, a projection of the rotating cutting blade can be achieved. 12 The lower surface of the base must be configured so that it is 0 mm. If the shaft is fixed... 44 When positioned at “60”, a projection of the rotating cutting blade can be achieved. 12 The lower surface of the base should be configured to be 60 mm, which indicates the maximum projection.

[0079] As in Fig. As shown in Figure 14, a reinforcing rib can be used.41c on the lower surface of the depth guide 41 (an inner circumferential surface of the arc-shaped part). The reinforcing rib 41e This ensures the rigidity of the depth guide with respect to deflection. In this way, since the rigidity of the depth guide 41 With regard to deflection, an actuating force can be applied to tilt the stop lever. 42 efficiently to the stop lever 42 be transferred. Accordingly, the operability of the stop lever can be affected. 52 It should be improved.

[0080] According to the cutting device 1 In this embodiment described above, an end position of the movement of the cutting device main body can be achieved. 10upwards, which is a position at the upper end within the area where the cutting depth can be adjusted (one side where the cutting depth becomes small) by the cutting depth stop mechanism 50 can be changed. Due to this design, the cutting depth stop mechanism can be appropriately set. 50 , when the cutting depth of the rotating cutting blade 12 Once adjusted, an adjustment to a target cutting depth can be carried out quickly, and the recoverability with regard to the cutting depth can be improved.

[0081] As described above, with a cutting depth adjustment mechanism that uses a prior art detent mechanism, fast and reliable positioning can be difficult. On the other hand, with the cutting depth stop mechanism 50 according to the embodiment by suitable adjustment of a position of the contact part 51in advance the movement of the main body of the cutting device 10 The final position of the upward movement is only needed once when the main body of the cutting device is in place. 10 up and down around the spindle 22 The cutting device is moved. This allows for accurate and quick positioning of the desired cutting depth. In this respect, the ease of use of the cutting device can be improved. 1 as well as the cutting depth adjustment mechanism 40 can be improved.

[0082] Furthermore, the cutting depth stop mechanism 50 according to this embodiment of the stop lever 52 between the depth guide 41 and the cutting blade housing 13 , i.e., away from the handle 14 (on one side opposite the handle) 14 in relation to depth control 41) in relation to a position in the base width direction perpendicular to the cutting direction. Due to this design, the stop lever can 52 not with a holding motion of the handle 14 interfere. Accordingly, high operability of the cutting device can be achieved. 1 can be achieved.

[0083] Furthermore, the cutting depth stop mechanism 50 according to the embodiment, the stop component 51 configured to do so by holding the depth guide 41 from both sides in the thickness direction and by tightening with the stop lever 52 is fixed. Furthermore, the thickness d of the depth guide can be adjusted. 41 in the direction of the base (towards the side of the lower part) they increase (thicken). Furthermore, the depth control can 41 the regulatory edge part 45 included, which includes an actuation range of the stop lever 52regulated. Due to this design, a relative position of the main lever part is possible. 52a with respect to the outer circumferential edge of the depth guide in an unlocked position of the stop lever 52 essentially with the radial direction independent of the top or bottom side (relative position of the depth guide) 51 (in a longitudinal direction). Thus, the operability of the stop lever can be adjusted. 52 It should be improved.

For example, in the embodiments described above, the cutting device has 1 the power cable 15 It is powered by an alternating current supply. However, the tilt stop mechanism can 30 and the cutting depth stop mechanism 50It can also be used with a cutting device that uses a battery as a power source or is operated with a direct current supply.

[0085] Furthermore, regarding the cutting depth stop mechanism 50 the stepped section 41b and / or the regulatory edge part 45 This is omitted. Furthermore, in this embodiment, the depth control can be... 41 It should be configured to be in a tapered shape, so that the thickness of the depth guide 41 becomes thicker towards a lower end part, thus creating an unlocking position for the stop lever. 52 with regard to the outer circumferential edge of the depth guide 41 with the radial direction on the side of the upper and lower parts. However, this configuration can also be omitted.
