Description

  The present invention relates to a guide rule for an electric saw that guides the electric saw to a cutting position by being attached to the electric saw.

  Generally, an electric saw (electric circular saw) is used by an operator by hand. When cutting a plate of a certain width from a base plate, an electric saw guide ruler (hereinafter, except for some) is used. A guide ruler is abbreviated), and this guide ruler is brought into contact with the side of the base plate to guide the electric saw to cut the target cutting position.

  Conventionally, as this type of guide ruler, a guide body for guiding an electric saw disclosed in Patent Document 1 is known. This guide body is intended to increase the commercial value of the guide body that guides the electric saw. Specifically, the guide body is provided on the electric saw and slides in contact with the end of the workpiece. A guide body configured such that a cutting portion formed by a saw blade is in parallel with an end portion of the workpiece, and slides in contact with the end portion of the workpiece. A plurality of ridges are formed on the portion, and the top of each ridge is configured to come into contact with the end of the object to be cut.

Utility Model Registration No. 3091101

  However, the conventional guide ruler (guide body) described above has a problem that it is not necessarily good in terms of usability.

  That is, this type of guide ruler is attached to the electric saw, and at the time of cutting, the electric saw is placed on the upper surface to be cut, and the guide plate portion of the guide ruler is brought into contact with the side to be cut. Thereby, it is possible to cut a certain width by following the cutting position of the electric saw to the side to be cut. On the other hand, the cutting work is not necessarily limited to such a constant width cutting, but also includes a cutting work such as cutting off the corners obliquely. In this case, a guide ruler is not necessary and the part to be cut off is long. In this case, the guide plate portion hits the object to be cut and returns to become an obstacle.

  Therefore, in this case, the conventional guide ruler (guide body) must be removed from the electric saw, and unnecessary loss is forced. Specifically, since the function of the guide ruler is to cut it to an accurate width dimension, it is very time consuming to attach the removed guide ruler to the electric saw again and adjust its position. In addition, the adjustment position is inevitably varied. Eventually, it became a factor that significantly reduced the work efficiency as a whole, as well as a decrease in quality due to variations in positional accuracy, and further difficulties in usability and functionality, such as delays in construction work and stress on the workers.

  An object of the present invention is to provide a guide ruler for an electric saw that solves the problems existing in the background art.

  An electric saw guide ruler 1 according to the present invention is provided with an adjustment rod portion whose mounting position can be adjusted with respect to the electric saw M and an adjustment rod portion on the tip side of the adjustment rod portion to solve the above-described problems. When the guide ruler is provided with the guide plate portion 3 integrally provided in the orthogonal direction Fs, the mounting rod body 2c attached to the electric saw M side divided into two at the predetermined position Xc and the guide rod portion provided with the guide plate portion 3 are provided. The adjusting rod portion 2 having 2g, the rotating portion 4 for rotatably connecting the mounting rod body 2c and the guide rod body 2g, and a rotation range within about 180 [°] of the operation lever 5bm provided integrally. A set position Xs or a mounting rod body 2c that has a bolt member 5b that allows or prevents the rotation of the rotating portion 4 and that can hold the mounting rod body 2c and the guide rod body 2g on a straight line. On the other hand, there is provided a rod restricting mechanism portion 5 that can be selectively switched to a release position Xr in which the guide rod body 2g is rotated and displaced, and at least the guide plate portion 2g can be held at a position away from the cutting object W during use. It is characterized by becoming.

  In this case, according to a preferred aspect of the invention, the rotating portion 4 and the rod restricting mechanism portion 5 can be configured to be non-contact with the cutting target W during use.

  The electric saw guide ruler 1 according to the present invention having such a configuration has the following remarkable effects.

  (1) When using the electric saw M, the cutting operation using the guide ruler 1 and the cutting operation not using it can be used properly. That is, even the electric saw M with the guide ruler 1 attached can be easily switched to the electric saw M without the guide ruler 1 attached without removing the guide ruler 1. Therefore, it is possible to greatly improve work efficiency, improve quality by eliminating variation in position accuracy, and further improve usability and functionality by eliminating delays in construction work and stress on workers. be able to.

  (2) Even if the guide ruler 1 is relatively long, the adjustment rod portion 2 can be folded in half as a secondary effect. As a result, the storability and portability of the guide ruler 1 can be improved.

  (3) The rod restricting mechanism portion 5 includes the bolt member 5b attached to the rotating portion 4 and allowing or preventing the rotation of the rotating portion 4 by the operation, so that the bolt member 5b can be loosened or tightened. Thus, it is possible to easily and reliably prevent or prevent the rotation of the rotation unit 4.

  (4) The operation lever 5bm is integrally provided on the bolt member 5b, and the operation lever 5bm is configured to allow or prevent the rotation of the rotation portion 4 within a rotation range within about 180 [°]. For example, the lever 5bm can be easily switched to a state related to permission or prevention with respect to the rotating portion 4 because the lever 5bm can be displaced only by simple operation.

  (5) According to a preferred embodiment, when the rotating portion 4 and the rod restricting mechanism portion 5 are configured so as to be non-contact with the cutting target W during use, the rotation added by the present invention during use. The adverse effect on the cutting object W due to the presence of the moving part 4 and the rod restricting mechanism part 5 can be eliminated, and basically, it can be used without impairing the usability of the conventional guide ruler.

  Next, preferred embodiments according to the present invention will be given and described in detail with reference to the drawings.

  First, in order to facilitate understanding of the guide ruler 1 for an electric saw according to the present embodiment, an outline of the electric saw M to which the guide ruler 1 is attached will be described with reference to FIG.

  FIG. 5 shows a typical electric circular saw Mr as the electric saw M. The electric circular saw Mr includes a base plate 50 and an electric circular saw body 60. The base plate 50 has a rectangular horizontal plate portion 51 and a pair of vertical plate portions 52 and 53 bent upward from the left and right sides of the horizontal plate portion 51. The electric circular saw body 60 is a horizontal plate. It is placed on the upper surface of the part 51. A part of the rotary sawtooth 61 protrudes downward from the opening 51 s provided in the horizontal plate 51. The pair of vertical plate portions 52 and 53 have insertion holes 52 s and 53 s for attaching the guide ruler 1 at positions close to the electric circular saw body 60, and the position of the guide ruler 1 on the upper surface of the horizontal plate portion 51. A fixing mechanism 54 for fixing is provided.

  Next, a specific configuration of the electric saw guide ruler 1 according to the present embodiment will be described with reference to FIGS. 1 to 5 (FIG. 6).

  As shown in FIG. 1, the guide ruler 1 roughly includes a basic configuration including an adjustment rod portion 2 and a guide plate portion 3. The adjusting rod portion 2 includes a mounting rod body 2c and a guide rod body 2g that are divided into two at a predetermined position Xc in accordance with the present invention. In addition, there is an advantage that the adjustment range of the adjustment rod portion 2 can be set wide by setting the predetermined position Xc as close to the guide plate portion 3 as possible.

  The mounting rod body 2c is a single rod formed in a straight line having a rectangular cross section, and the length can be arbitrarily selected in consideration of the cutting width of the cutting object W (see FIG. 6). The mounting rod body 2c can be detachably attached to the base plate 50 of the electric circular saw Mr by inserting the insertion hole 52s, the fixing mechanism 54, and the insertion hole 53s in this order. Therefore, the cross-sectional shape of the mounting rod body 2c is substantially matched with the shapes of the insertion holes 52s and 53s. Further, since the position of the mounting rod body 2c can be fixed or released by operating the handle 54h of the fixing mechanism 54, the mounting position can be adjusted with respect to the electric circular saw Mr. The mounting rod body 2 c at the time of insertion is parallel to the axis of the rotary saw tooth 61.

  On the other hand, the guide rod body 2g uses a single rod that is the same as the mounting rod body 2c, and the length of this rod is made different (shortened) and, as shown in FIG. To do. Then, the guide plate portion 3 is fixed to one end (tip) located below the guide rod body 2g. Thereby, the guide plate part 3 is integrally provided in the orthogonal direction Fs with respect to the guide rod body 2g.

  Further, the other end of the guide rod body 2g is rotatably connected to one end (tip) of the mounting rod body 2c via the rotating portion 4, and the rotation of the rotating portion 4 is restricted. A possible rod restricting mechanism 5 is provided. As shown in FIG. 1, the rotating portion 4 has a pair of brackets 11 and 12 raised on the upper surface in the vicinity of one end of the mounting rod body 2c, and the bracket 13 is raised on the upper surface in the vicinity of the other end of the guide rod body 2g. The bracket 13 is inserted between the brackets 11 and 12. As shown in FIG. 4, the bracket 11 and the bracket 13 are formed with insertion holes 11 s and 13 s through which the bolt member 5 b is inserted, and the bracket 12 is screwed into a screw hole 12 n into which the screw of the bolt member 5 b is screwed. Form. Accordingly, if the bolt member 5b is inserted in the order of the insertion holes 11s and 13s and screwed into the screw hole 12n, the rotating part 4 is configured, and the guide rod body 2g rotates relative to the mounting rod body 2c. Via the part 4, it is connected so that rotation is possible. Furthermore, the guide rod body 2g is rotationally displaced relative to the set position Xs where the mounting rod body 2c and the guide rod body 2g can be held in a straight line, or the mounting rod body 2c, and the guide plate portion 2g is to be cut at least in use. A rod restricting mechanism portion 5 that can be selectively switched to a release position Xr that can be held at a position separated from W is configured.

  On the other hand, the operation lever 5bm is integrally provided on the head 5bh of the bolt member 5b, and the rotation of the rotation unit 4 is allowed or prevented within a rotation range within approximately 180 ° of the operation lever 5bm. The size of the screw pitch of the bolt member 5b is selected. If comprised in this way, since it becomes possible only by the simple operation which displaces the operation lever 5bm back and forth, for example, there exists an advantage which can be switched easily to the state which is related with the permission or prevention with respect to the rotation part 4.

  Moreover, with such a configuration, the rotating unit 4 and the rod regulating mechanism unit 5 are not in contact with the cutting target W during use. Therefore, the adverse effect on the cutting object W due to the presence of the rotating portion 4 and the rod restricting mechanism portion 5 added by the present invention can be eliminated, and basically, the conventional guide ruler can be used without impairing usability. Further, when the rod restricting mechanism portion 5 is configured, the bolt member 5b is provided so as to be attached to the rotation portion 4 and allow or prevent the rotation of the rotation portion 4 by the operation. Alternatively, there is an advantage that it is possible to easily and reliably prevent or prevent the rotation of the rotation unit 4 by the tightening operation.

  In the rotating part 4 and the rod restricting mechanism part 5, since the bolt member 5b can be loosened by rotating the operation lever 5bm in the direction of the arrow Fo (counterclockwise direction) in FIG. Is allowed to rotate. As a result, the guide rod body 2g can be rotated in the direction of arrow Fp (clockwise) in FIG. 1, and the guide rod body 2g can be rotated relative to the end surface (divided surface) at one end of the mounting rod body 2c. The end surface (division surface) at the other end can be brought into contact. Accordingly, in this state, one end side of the mounting rod body 2c and the other end side of the guide rod body 2g are arranged on a straight line. In this state, the operation lever 5bm is moved in the direction of arrow Fq (clockwise in FIG. If it is rotated in the direction), the bolt member 5b can be tightened to prevent the rotation part 4 from rotating. That is, it can be used as the guide ruler 1 at the set position Xs.

  On the other hand, when the operation lever 5bm is rotated in the direction of arrow Fo (counterclockwise) in FIG. 1, the guide rod body 2g can be rotated in the direction of arrow Fn (counterclockwise) in FIG. In other words, it can be folded in two, and the upper surface side of the guide rod body 2g overlaps the upper surface of the mounting rod body 2c, as indicated by phantom lines in FIG. That is, the release position Xr is obtained, and the substantial function of the guide ruler 1 can be lost. At the release position Xr, the bolt member 5b may be loosened or tightened. If it is in the tightened state, the rotation of the rotation part 4 can be prevented, so that the relative position (relative angle) of the guide rod body 2g with respect to the mounting rod body 2c can be fixed.

  Next, a method of using the electric saw guide ruler 1 according to the present embodiment will be described with reference to FIGS.

  First, a cutting operation using the guide ruler 1 will be described. In this case, the guide ruler 1 sets the guide ruler 1 to the set position Xs as shown by the solid line in FIG. 6 (FIG. 7) and FIG. That is, the rotation of the rotation part 4 is permitted by rotating the operation lever 5bm in the direction of arrow Fo in FIG. 1 and loosening the bolt member 5b. Then, the guide rod body 2g is rotated in the direction of the arrow Fp to bring the divided surface of the guide rod body 2g into contact with the divided surface of the mounting rod body 2c. The rotation of the rotating part 4 is prevented by rotating in the direction of arrow Fq and tightening the bolt member 5b. As a result, the set position Xs that functions as the original guide ruler 1 can be obtained.

  On the other hand, the guide ruler 1 is attached to the electric circular saw Mr. In this case, as shown in FIG. 5, the adjustment rod portion 2 (mounting rod body 2c) in the guide ruler 1 is inserted through the insertion hole 52s, the fixing mechanism 54, and the insertion hole 53s in this order. At this time, the fixing mechanism 54 is brought into a fixed release state by operating the handle 54h. Then, by adjusting the position of the guide plate portion 3 with respect to the rotating saw blade 61, the cutting width Lc shown in FIG. 6 is set, and if set, the handle 54h is operated, and the position of the adjusting rod portion 2 is adjusted by the fixing mechanism 54. Fix it.

  Thereby, the cutting operation by the electric circular saw Mr using the guide ruler 1 can be performed. 6 and 7 schematically show the state of the cutting operation. The illustration assumes a case in which an unnecessary portion Wr is cut off from a cutting target W such as a base plate material over a certain width. At the time of cutting, the base plate 50 of the electric circular saw Mr is placed on the upper surface of the cutting target W while the guide plate portion 3 is in contact with the side Wrs of the cutting target W, and the rotary saw blade 61 is positioned at the cutting start position. To be located. And if the guide plate part 3 is slid and moved in contact with the side Wrs, the rotary saw blade 61 of the electric circular saw Mr can be cut along the cutting line Kc. As a result, the unnecessary portion Wr having a certain width can be cut off from the cutting target W.

  Next, a case where an oblique cutting operation is performed on the cutting target W from which the unnecessary portion Wr has been removed without using the guide ruler 1 will be described. In this case, the guide plate portion 3 is displaced to the release position Xr indicated by the phantom line in FIG. That is, the rotation of the rotation part 4 is permitted by rotating the operation lever 5bm in the direction of arrow Fo in FIG. 1 and loosening the bolt member 5b. Then, the guide rod body 2g is rotated and displaced by approximately 180 ° in the direction of the arrow Fn. Thereby, the one adjustment rod part 2 will be in the state folded in half with the predetermined position Xc as a fulcrum, and the guide plate part 3 turned upside down will overlap with the upper surface of the attachment rod body 2c.

  Thereby, the release position Xr that does not function as the guide ruler 1 can be set. Therefore, even when the guide ruler 1 is attached, the cutting operation by the electric circular saw Mr can be performed without causing the guide ruler 1 to function. 8 and 9 schematically show the state of the cutting operation. The illustration assumes a case where the cutting target W is cut obliquely along the cutting line Ke. At the time of cutting, the base plate 50 of the electric circular saw Mr is placed on the upper surface of the cutting target W, and the rotary saw blade 61 is positioned at the cutting start position. And if the rotary saw blade 61 of the electric circular saw Mr is moved along the cutting line Ke, an oblique cutting with respect to the cutting object W can be performed.

  By the way, at this time, the guide ruler 1 is kept at the set position Xs, that is, in the conventional guide ruler, the guide plate portion 3 is at the position of the virtual line 3s shown in FIG. Therefore, the guide plate portion 3 hits the cutting target W during cutting and cannot be cut. After all, the conventional guide ruler has to be removed from the electric circular saw Mr each time. However, in the guide ruler 1 according to the present embodiment, the guide ruler 1 is originally attached to the electric circular saw Mr. The guide ruler 1 can be used without substantially functioning.

  On the other hand, FIG. 10 shows a guide ruler 1 according to a reference example. The guide ruler 1 is provided with a spring mechanism 6 for biasing and holding the guide rod body 2g that is locked to the mounting rod body 2c at the set position Xs when the rod regulating mechanism portion 5 is configured, and the mounting rod The holding mechanism 7 for holding the guide rod body 2g at the release position Xr is provided with respect to the body 2c.

  In this case, the rotating unit 4 has the same function as that of the above-described embodiment shown in FIGS. 1 to 5, but instead of the bolt member 5b, a simple round bar-shaped shaft 5s is used. It was configured to move freely. Further, the shaft 5s protrudes to one side of the rotating portion 4, and a coil spring 6s is attached to the protruded shaft 5s, and one end of the coil spring 6s is locked to the bracket 11, and the other end of the coil spring 6s. The spring mechanism 6 that urges the guide rod body 2g in the direction in which the guide rod body 2g is held at the set position Xs by engaging the bracket 13 with the bracket 13 is configured. Furthermore, the holding mechanism 7 is configured by integrally forming the protrusion 13c on the bracket 13 and providing a locking mechanism 7s on the upper surface of the mounting rod body 2c. The locking mechanism 7s includes a support bracket 23 fixed to the upper surface of the mounting rod body 2c and a locking member 22 whose one end is rotatably supported by the support bracket 23. As shown in FIG. 10, the upper surface of the mounting rod body 2c is tilted. In addition, although the case where the shaft 5s protrudes to one side of the rotating portion 4 is shown, a pair of coil springs 6s and 6s may be arranged on both sides by protruding on both sides.

  Accordingly, when the guide ruler 1 is used, as shown by the solid line in FIG. 10, if the guide rod body 2g is positioned at the set position Xs, the guide rod body 2g is urged by the spring mechanism 6, and the guide rod The split surface of the body 2g is held in pressure contact with the split surface of the mounting rod body 2c. On the other hand, when the guide ruler 1 is not used, the guide rod body 2g is rotationally displaced upward against the urging force of the spring mechanism 6, as indicated by phantom lines in FIG. Thereby, since the protrusion 13c is pivotally displaced downward, the return of the guide rod body 2g may be prevented by hooking the locking portion 22c on the other end side of the locking member 22 to the protrusion 13c. As a result, the guide rod body 2g (guide plate portion 3) is held at the release position Xr. Therefore, even the guide ruler 1 according to the reference example shown in FIG. 10 can be used similarly because it can be switched to the set position Xs or the release position Xr similarly to the guide ruler 1 shown in FIGS. At the same time, the same basic effect can be obtained.

  As described above, the guide ruler 1 shown in FIG. 10 has a spring mechanism that biases and holds the guide rod body 2g that is locked to the mounting rod body 2c at the set position Xs when the rod restriction mechanism portion 5 is configured. 6 and a holding mechanism 7 for holding the guide rod body 2g at the release position Xr with respect to the mounting rod body 2c. Therefore, the holding rod 7 can be held using the biasing action of the spring mechanism 6. Therefore, there is an advantage that the holding stability can be improved, for example, the mounting rod body 2c and the guide rod body 2g can be prevented from rattling at the set position Xs and the release position Xr. In addition, in the guide ruler 1 shown in FIG. 10, the same parts as those of the guide ruler 1 shown in FIGS. 1 to 5 are denoted by the same reference numerals to clarify the configuration, and detailed description thereof is omitted.

  Therefore, according to the guide ruler 1 according to this embodiment, when using the electric circular saw Mr, it is possible to easily use a cutting operation using the guide ruler 1 and a cutting operation not using it. That is, even with the electric circular saw Mr with the guide ruler 1 attached, it is possible to easily switch to the electric circular saw Mr with the guide ruler 1 not substantially attached without removing the guide ruler 1. . Therefore, it is possible to greatly improve work efficiency, improve quality by eliminating variation in position accuracy, and further improve usability and functionality by eliminating delays in construction work and stress on workers. be able to.

  In addition, even if the guide ruler 1 is relatively long, as a secondary effect, the adjustment rod portion 2 can be folded in two, so that the storage and portability of the guide ruler 1 can be improved. .

  As mentioned above, although preferred embodiment was described in detail, this invention is not limited to such embodiment, It does not deviate from the summary of this invention in a detailed structure, a shape, a material, quantity, a numerical value, etc. It can be changed, added, or deleted arbitrarily.

  For example, the rotating unit 4 and the rod restricting mechanism unit 5 are desirably configured to be non-contact with the cutting target W during use, but this does not exclude the case of contact depending on the shape or the like. In addition, although the electric circular saw Mr was shown as an example as the electric saw M, it can be similarly used for other electric saws M, such as an electric reciprocating saw having a reciprocating saw blade.

  The guide ruler for an electric saw according to the present invention can be used for various electric saws such as an electric circular saw and an electric reciprocating saw.
