Description

The present invention relates to a guide device for a saw that holds a saw blade for cutting a material to be cut during cutting of the material to be cut.

2. Description of the Related Art Patent Document 1 discloses a jig for a hand saw as an example of a saw guide device that holds a saw blade for cutting a material to be cut during cutting of the material to be cut.

A hand saw jig disclosed in Patent Document 1 includes a guide base and a saw blade guide plate. The guide base is placed on the material to be cut, and the saw blade is reciprocated while holding the saw blade between the front surface of the guide base and the rear surface of the saw blade guide plate to cut the material to be cut.

Further, in the hand saw jig disclosed in Patent Document 1, a spacer having the same thickness as the saw blade is sandwiched between the front surface of the guide base and the rear surface of the saw blade guide plate. Thereby, the gap between the front surface of the guide base and the rear surface of the saw blade guide plate is set to an appropriate size.

Japanese Patent No. 4558264

In the hand saw jig disclosed in Patent Document 1, as described above, the spacer adjusts the gap between the front surface of the guide base and the rear surface of the saw blade guide plate. Therefore, the saw blade that can be held by the hand saw jig is limited to one having the same thickness as the spacer.

If the saw blade were sandwiched between the front surface of the guide base and the rear surface of the saw blade guide plate without a spacer, the following problems would arise. When the saw blade is strongly pinched, the entire front and rear surfaces are pressed against the saw blade, making it difficult to reciprocate the saw blade. In addition, when the saw blade is held weakly, the saw blade tends to be displaced during cutting.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to solve the above-mentioned problems, and to provide a guide device for a saw that can use saw blades of various thicknesses and that facilitates adjustment of the gap between the members that sandwich the saw blade. to do.

In order to achieve the above object, the present invention is configured as follows.

FIG. 2 is a plan view of the saw guide device set on the material to be cut and with the saw blade set. FIG. 3 is a perspective view of a saw guide device according to a modification of one embodiment of the present invention;

A saw guide device according to an aspect of the present invention includes:
A base member having a first contact surface that contacts the saw blade, and a supported surface that is supported by a material to be cut by the saw blade and that intersects an imaginary surface including the first contact surface. and,
a clamping member having a second contact surface that faces the first contact surface and clamps the saw blade between the first contact surface and the first contact surface;
The base member and the clamping member are connected on the side opposite to the supported surface with respect to the second contact surface in an orthogonal direction orthogonal to the supported surface, and the second contact surface and the first contact surface are connected to each other. and a connection part that can adjust the size of the gap,
One of the first contact surface and the second contact surface approaches the other of the first contact surface and the second contact surface as it approaches the supported surface from the connecting portion in the orthogonal direction. It is inclined with respect to the other of the first contact surface and the second contact surface.

According to this configuration, the size of the gap between the first contact surface and the second contact surface can be arbitrarily adjusted by the connecting portion. Thereby, the first contact surface and the second contact surface can clamp saw blades of various thicknesses.

According to this configuration, one of the first contact surface and the second contact surface approaches the other of the first contact surface and the second contact surface as it approaches the supported surface from the connecting portion in the orthogonal direction. It is inclined with respect to the other of the contact surface and the second contact surface. As a result, a part of the first contact surface and the second contact surface pinches the saw blade from both sides and presses the saw blade 91, while other parts do not press the saw blade from both sides. . As described above, since the pressure contact areas of the first contact surface and the second contact surface with respect to the saw blade are small, the strength of the pressure contact with the saw blade has little effect on the reciprocating motion of the saw blade. Therefore, according to this configuration, even when the saw blade is sandwiched between the first contact surface and the second contact surface, the saw blade can easily reciprocate.

According to this configuration, the strength of pressure contact with the saw blade has little effect on the reciprocating motion of the saw blade. can be sandwiched. In other words, it is easy to adjust the gap between the members sandwiching the saw blade.

A saw guide device according to an aspect of the present invention may further include a positioning member having a positioning surface and being detachable from the base member. In the saw guide device, when the positioning member is attached to the base member, the positioning surface may be perpendicular to a virtual plane including the supported surface, and at least a part of the positioning surface may be perpendicular to the supporting surface. The first contact surface and the second contact surface may be positioned opposite to the supported surface in the direction.

According to this configuration, the saw guide device can be positioned with respect to the material to be cut by bringing the positioning surface into contact with the side surface of the material to be cut.

In the saw guide device, the positioning member may be fixed to the base member at any position in the orthogonal direction with respect to the base member.

With this configuration, the position of the positioning member with respect to the base member can be changed according to the thickness of the material to be cut. Therefore, even if the material to be cut is thin, the projection length of the positioning member from the supported surface can be made shorter than the thickness of the material to be cut. In addition, when the material to be cut is thick, the contact area of the positioning surface with the side surface of the material to be cut can be increased by lengthening the projection length of the positioning member from the supported surface.

In the saw guide device, the base member includes a first member to which the positioning member is attachable and detachable, and a second member having the first contact surface and detachable from the first member. Alternatively, the connecting portion may connect the second member and the clamping member, and the supported surface may be formed on at least one of the first member and the second member. One of the first member and the second member may include a plurality of protrusions, and the other of the first member and the second member may include a plurality of recesses. The second member may be attached to the first member in different postures depending on the combination of fitting of a portion and at least a portion of the plurality of recesses.

According to this configuration, the structure for attaching and detaching the second member to and from the first member is a simple structure of fitting the convex portion and the concave portion. Therefore, the second member can be attached/detached to/from the first member more easily than the configuration in which the second member is attached/detached to/from the first member by screwing or the like.

According to this configuration, the second member can be attached to the first member in different postures simply by changing the fitting combination of the plurality of protrusions and the plurality of recesses. Accordingly, by changing the direction of the first contact surface according to each of the different postures, the cutting direction of the saw blade with respect to the material to be cut can be changed in various directions.

In the saw guide device, the plurality of protrusions may include a first protrusion and a second protrusion, and the plurality of recesses may include a first recess, a second recess, and a third recess. good too. In the saw guide device, the second member is configured such that the first concave portion and the first convex portion are fitted together and the second concave portion and the second convex portion are fitted together, so that the second member is in the first posture. It may be attached to the first member, and may be attached to the first member in a second posture by fitting the third concave portion and the first convex portion, and the third concave portion and the second convex portion may be attached to the first member. The first member may be mounted in the third posture by fitting the protrusions. In the saw guide device, when viewed from the orthogonal direction, the first contact surface of the second member in the second posture is the first contact surface of the second member in the first posture. The first contact surface of the second member in the third posture may form an angle with respect to the first contact surface of the second member in the first posture when viewed from the orthogonal direction. may form a second angle.

According to this configuration, the second member can take three postures by changing the fitting combination of the first convex portion and the second convex portion and the first concave portion, the second concave portion, and the third concave portion. can be done.

In the saw guide device, the first corner and the second corner may have the same size, and the first contact surface of the second member in the second posture and the contact surface of the second member in the third posture may have the same size. The first contact surface of the second member may face in the opposite direction.

According to this configuration, by simply switching the posture of the second member between the second posture and the third posture, the direction of the saw blade sandwiched between the first contact surface and the second contact surface becomes line symmetrical with each other. Orientation can be set.

In the saw guide device, each of the plurality of projections may be composed of a plurality of projections, and each of the plurality of recesses may be composed of a plurality of depressions.

According to this configuration, compared to a base member in which each of the plurality of protrusions is configured by one protrusion and each of the plurality of recesses is configured by one depression, the distance between the fitted protrusions and recesses is reduced. rattling can be reduced.

The saw guide device according to one aspect of the present invention may further include a clamp member that is detachable from the base member and that is attached to the base member so as to face the positioning surface of the positioning member. . In the saw guide device, the clamp member has a main body that can be attached to and detached from the base member, and a facing surface that is positioned between the positioning member and the main body and faces the positioning surface. and a moving member supported by the main body movably along a direction perpendicular to the.

According to this configuration, when the material to be cut is in the shape of a thin rod or the like, the material to be cut can be sandwiched between the positioning surface and the facing surface. As a result, the posture of the saw guide device with respect to the material to be cut can be stabilized.

In the saw guide device, the clamp member may be fixable to the base member at any position in the orthogonal direction with respect to the base member.

According to this configuration, the position of the clamp member with respect to the base member can be changed according to the thickness of the material to be cut. Therefore, even if the material to be cut is thin, the projection length of the clamp member from the supported surface can be made shorter than the thickness of the material to be cut.

In the saw guide device, the moving member may include a threaded portion passing through the main body, and a facing portion provided at the end of the threaded portion on the positioning surface side and having the facing surface. Preferably, the moving member may move relative to the main body along a direction orthogonal to the positioning surface by rotating the threaded portion about an axis.

According to this configuration, the distance from the positioning surface of the opposing surface can be changed simply by rotating the threaded portion.

In the saw guide device, the base member may include a pair of mounting portions facing each other, and the positioning member and the clamping member can be selectively mounted to each of the pair of mounting portions. may

According to this configuration, by exchanging the attachment positions of the positioning member and the clamp member selectively attached to each of the pair of attachment portions, the saw guide device can be changed from the right-handed specification to the left-handed specification or from the left-handed specification. Can be switched to right-handed specifications.

In the saw guide device, at least a portion of the base member including the first contact surface and a portion of the clamping member including the second contact surface may be made of resin.

If at least one of the first contact surface and the second contact surface is made of metal, the saw blade reciprocatingly moves while being sandwiched between the first contact surface and the second contact surface. It may be damaged by rubbing against the contact surface and the second contact surface. According to this configuration, since the first contact surface and the second contact surface are made of resin, it is possible to reduce the possibility that the saw blade will be damaged.

Depending on the thickness of the saw blade 91 sandwiched between the contact surface 30A of the sandwiching member 30 and the contact surface 22A of the second member 22, the screwing position of the nut 42 with respect to the screw 41 changes. That is, the connecting portion 40 (screw 41 and nut 42) can adjust the size of the gap between the contact surface 30A of the clamping member 30 and the contact surface 22A of the second member 22. FIG.

In addition, the connection part 40 is not limited to the configuration of the screw 41 and the nut 42 . The connecting part 40 may have another known structure, provided that it connects the base member 20 and the clamping member 30 and the size of the gap between the contact surfaces 22A and 30A can be adjusted.

The upper portion of the contact surface 30A of the holding member 30 is inclined with respect to the Y direction so as to move forward as it goes downward. In other words, the upper portion of the contact surface 30A of the clamping member 30 moves toward the contact surface 22A of the second member 22 as it approaches the lower surface 22B of the second member 22 from the connecting portion 40 in the Y direction. is sloping. The lower portion of the contact surface 30A of the holding member 30 spreads in the X direction and the Y direction similarly to the contact surface 22A of the second member 22 .

The through hole 61B communicates with the outside of the main body 61 via an opening 61C.

Each projection 611 engages with each groove 21C of the first member 21 . As a result, when the main body 61 is attached to the first member 21, the main body 61 is prevented from being displaced, such as being rotated, with respect to the first member.

Clamp member 60 is attached to first member 21 by screw 63 and nut 64 . The screw 63 passes through the through hole 61A from the left and then passes through the notch 21B of the first member 21 . The nut 64 is screwed onto the screw 63 passing through the notch 21B of the first member 21 from the right side. As a result, the main body 61 and the first member 21 are fixed between the grip portion 63A of the screw 63 and the nut 64, and the clamp member 60 is attached to the first member 21, as shown in FIG. The grip portion 63A is a portion that is gripped by the user when the screw 63 is passed through the through hole 61A and the notch 21B.

The threaded portion 621 has a grip portion 621A. The grip portion 621A is a portion that is gripped by the user when the threaded portion 621 is passed through the through hole 61B.

The nut 623 is inserted into the through hole 61B through the opening 61C and arranged in the through hole 61B. As a result, the threaded portion 621 inserted into the through hole 61B is screwed with the nut 623 . The threaded portion 621 moves leftward relative to the main body 61 by rotating about the axis in the first direction. The threaded portion 621 moves rightward relative to the main body 61 by rotating about the axis in a second direction opposite to the first direction. That is, the moving member 62 moves relative to the main body 61 along the X direction as the threaded portion 621 rotates about its axis.

The facing portion 622 is screwed onto the tip portion of the threaded portion 621 . The tip of the threaded portion 621 is the end of the threaded portion 621 opposite to the grip portion 621A. In other words, the tip of the threaded portion 621 is the end of the moving member 62 on the positioning surface 50A side. The facing portion 622 has a facing surface 622A. 622 A of opposing surfaces are surfaces on the opposite side to the part screwed with the screw part 621 among the opposing parts 622. As shown in FIG. The facing portion 622 is positioned between the main body 61 and the positioning member 50 .

The facing surface 622A can come into contact with a material to be cut located between the positioning surface 50A and the positioning surface 50A, as will be described later. The position of the moving member 62 in the X direction changes according to the width (length in the X direction) of the material to be cut located between the facing surface 622A and the positioning surface 50A. Specifically, the longer the width of the material to be cut, the more the position of the moving member 62 shifts to the left, and the shorter the width of the material to be cut, the more the position of the moving member 62 shifts to the right. That is, the moving member 62 is supported by the main body 61 so as to be movable along the X direction perpendicular to the positioning surface 50A.

In addition, in the saw guide device 10, the screw and the nut may be made of resin. Further, in the saw guide device 10, the other portions may be made of metal. However, in the saw guide device 10, the portion including the contact surface 22A (the second member 22 of the base member 20 in this embodiment) and the portion including the contact surface 30A (the clamping member 30 in this embodiment) are made of resin. preferably configured. That is, it is preferable that at least the portion including the contact surface 22A in the base member 20 and the portion including the contact surface 30A in the holding member 30 are made of resin.

Further, the constituent materials of the saw guide device 10 are not limited to those described above. For example, at least part of the saw guide device 10 may be made of materials other than resin and metal, such as wood or ceramics.

<Usage example>
An example of use of the saw guide device 10 will now be described.

FIG. 9 is a perspective view of the saw guide device set on the material to be cut and with the saw blade set.

As shown in FIG. 9 , the positioning member 50 is attached to the first member 21 of the base member 20 . Next, the base member 20 and the positioning member 50 are placed on the material 92 to be cut. At this time, the lower surfaces 21A and 22B of the base member 20 contact the upper surface 92C of the material 92 to be cut, so that the saw guide device 10 is positioned vertically (in the Y direction) with respect to the material 92 to be cut. Further, the saw guide device 10 is positioned laterally (in the X direction) with respect to the material to be cut 92 by the positioning surface 50A of the positioning member 50 coming into contact with the side surface 92D of the material to be cut 92 .

Also, at this time, the position of the positioning member 50 in the Y direction with respect to the first member 21 can be adjusted according to the thickness (the length in the Y direction) of the material to be cut 92 .

A saw blade 91 is sandwiched between the second member 22 of the base member 20 and the sandwiching member 30 . As a result, the saw blade 91 is set in the saw guide device 10 .

The order of mounting, placing, and adjusting each member and setting the saw blade 91 is arbitrary.

With the saw guide device 10 supported by the material to be cut 92 and the saw blade 91 set on the saw guide device 10, the saw blade 91 is reciprocated in the X direction. Thereby, the material to be cut 92 is cut.

FIG. 10 is a plan view of the saw guide device set on the material to be cut and with the saw blade set.

FIG. 10 shows an example of use of the saw guide device 10 when the second member 22 is attached to the first member 21 in the second posture. When the second member 22 is attached to the first member 21 in the second posture, the material 92 to be cut can be cut at an angle of 45 degrees with respect to the side surface 92D.

The example of use shown in FIG. 9 described above is an example of use of the saw guide device 10 when the second member 22 is attached to the first member 21 in the first posture.

Also, although not shown, when the second member 22 is attached to the first member 21 in the third posture, the same operation is performed as when the second member 22 is attached to the first member 21 in the second posture. , the saw guide device 10 can be used.

<Effects of this embodiment>
According to this embodiment, the size of the gap between the contact surfaces 22A and 30A can be arbitrarily adjusted by the connecting portion 40. FIG. As a result, the contact surfaces 22A and 30A can clamp saw blades of various thicknesses.

According to this embodiment, the contact surface 30A is inclined with respect to the contact surface 22A so as to approach the contact surface 22A from the connecting portion 40 toward the lower surfaces 21A and 22B in the Y direction. As a result, the lower portions of the contact surfaces 22A and 30A sandwich and press the saw blade 91 from both sides to sandwich the saw blade 91, while the upper portions of the contact surfaces 22A and 30A do not press the saw blade 91 from both sides. Since the contact surfaces 22</b>A and 30</b>A have a small pressure contact area with respect to the saw blade 91 , the strength of the pressure contact with the saw blade 91 has little effect on the reciprocating motion of the saw blade 91 . Therefore, according to this embodiment, even when the saw blade 91 is sandwiched between the contact surfaces 22A and 30A, the saw blade 91 can be easily reciprocated.

According to the present embodiment, the strength of the pressure contact with the saw blade 91 has little effect on the reciprocating motion of the saw blade 91. Therefore, the contact surfaces 22A and 30A of the saw blade can be operated without worrying about the strength of the pressure contact with the saw blade 91. 91 can be sandwiched. That is, it is easy to adjust the gap between the second member 22 and the holding member 30 that hold the saw blade 91 therebetween.

According to this embodiment, the saw guide device 10 can be positioned with respect to the material to be cut 92 by bringing the positioning surface 50A into contact with the side surface 92D of the material to be cut 92, as shown in FIG.

According to this embodiment, the position of the positioning member 50 with respect to the base member 20 can be changed according to the thickness (length in the Y direction) of the material 92 to be cut. Therefore, even if the material 92 to be cut is thin (short in the Y direction), the projection length from the lower surfaces 21A and 22B of the positioning member 50 can be made shorter than the thickness of the material 92 to be cut. In addition, when the material to be cut 92 is thick (long in the Y direction), the contact area of the positioning surface 50A with the side surface 92D of the material to be cut 92 can be increased by increasing the protruding length from the lower surfaces 21A and 22B of the positioning member 50. You can make it bigger.

According to this embodiment, the structure for attaching and detaching the second member 22 to and from the first member 21 is a simple structure of fitting the convex portion 24 and the concave portion 23 . Therefore, the second member 22 can be attached/detached to/from the first member 21 more easily than the configuration in which the second member 22 is attached/detached to/from the first member 21 by screwing or the like.

According to this embodiment, the second member 22 can be attached to the first member 21 in different postures simply by changing the fitting combination of the plurality of protrusions 24 and the plurality of recesses 23 . Accordingly, by changing the orientation of the contact surface 22A according to each of the different postures, the cutting orientation of the saw blade 91 with respect to the material to be cut 92 can be changed in various orientations.

According to this embodiment, the second member 22 can assume three postures by changing the fitting combination of the protrusions 241 and 242 and the recesses 231 , 232 and 233 .

According to the present embodiment, by simply switching the posture of the second member 22 between the second posture and the third posture, the orientation of the saw blade 91 sandwiched by the contact surfaces 22A and 30A is symmetrical with each other. can be set.

According to this embodiment, each of the plurality of projections 24 is composed of two protrusions, and each of the plurality of recesses 23 is composed of two depressions. Therefore, compared to the base member 20 in which each of the plurality of protrusions 24 is configured by one protrusion and each of the plurality of recesses 23 is configured by one depression, the protrusions 24 and the recesses 23 are fitted together. It is possible to reduce the backlash between them.

According to this embodiment, when the material to be cut 92 is in the shape of a thin rod or the like, the material to be cut 92 can be sandwiched between the positioning surface 50A and the facing surface 622A (see FIG. 8). As a result, the posture of the saw guide device 10 with respect to the material 92 to be cut can be stabilized.

According to this embodiment, the position of the clamp member 60 with respect to the base member 20 can be changed according to the thickness (length in the Y direction) of the material 92 to be cut. Therefore, even if the material 92 to be cut is thin, the length of protrusion of the clamp member 60 from the lower surfaces 21A and 22B can be made shorter than the thickness of the material 92 to be cut.

According to this embodiment, the distance of the facing surface 622A from the positioning surface 50A can be changed simply by rotating the threaded portion 621 .

If at least one of the contact surfaces 22A and 30A is made of metal, the saw blade 91, when sandwiched between the contact surfaces 22A and 30A and reciprocated, rubs against the contact surfaces 22A and 30A. You may get hurt. According to this embodiment, since the contact surfaces 22A and 30A are made of resin, the possibility of the saw blade 91 being damaged can be reduced.

On the other hand, when the user of the saw guide device 10 is left-handed, the configuration shown in FIG. 11 is used.

According to this modification, by exchanging the attachment positions of the positioning member 50 and the clamp member 60 selectively attached to each of the pair of notches 21B, the saw guide device 10 can be changed from right-handed specifications to left-handed specifications. Alternatively, it is possible to switch from left-handed specifications to right-handed specifications.
