Description

[Technical field]

[0001] The present invention relates to a panel cutting guide device that is used when cutting a panel such as a fence. [Background technology]

[0002] When installing panels such as fences, panels are prepared in advance in a manufacturing factory to a standard size, and then cut to the desired dimensions at the installation site. An electric cutter device having a blade such as a circular saw and a guide member for guiding the electric cutter device are used to cut the panels. That is, with the panel placed horizontally, a guide member is placed on the top surface of the panel along the cutting position, and the panel is cut by moving the base of the electric cutter along the guide member (for example, see Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2023-62840 A Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, some panels to be cut have a surface material such as a lattice or net disposed between two frame materials. In this type of panel, if the frame material is wider than the surface material, a step occurs between the surface material and the frame material. For such panels, when a guide member is placed across two frame materials, a gap is created between the guide member and the surface material, and there is a risk that the base of the electric cutter device will get into this gap when the electric cutter device is moved along the guide member. If the base gets into the gap between the guide member and the surface material, it becomes difficult to move the electric cutter device along the guide member, and there is a concern that problems such as a shift in the cutting position will occur.

[0005] SUMMARY OF THE PRESENT DISCLOSURE In view of the above-mentioned circumstances, an object of the present invention is to provide a guide device for cutting a panel that can accurately cut a panel even when there is a step between a frame material and a surface material. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, the panel cutting guide device of the present invention is a panel cutting guide device that is applied when a panel having a face material between two frame materials is cut by an electric cutter device having a blade protruding from a base, and is characterized in that it comprises a slide guide that is arranged across the two frame materials and on which the base is slidably placed on its front surface with the blade protruding from the back surface, and a guide rail that protrudes from the front surface of the slide guide and abuts against the base placed on the slide guide. Effect of the Invention

[0007] According to the present invention, since the base of the electric cutter device is placed on the surface of the slide guide that is placed across the frame material, even if there is a step between the frame material and the surface material, the electric cutter device can be moved along the guide rail, making it possible to cut the panel accurately. Moreover, since there is no direct contact between the panel and the base of the electric cutter device, there is no need to protect the panel prior to the cutting operation, making it possible to easily cut the panel.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of a panel cutting guide device according to the present invention will be described in detail with reference to the accompanying drawings.

[0010] Fig. 1 shows an example of application of a panel cutting guide device according to an embodiment of the present invention. The panel cutting guide device 10 illustrated here is applied when a fence (panel) 20, previously configured to a fixed shape (e.g., 2m wide in the left-right direction), is cut to a desired width dimension by an electric cutter device 30 at the installation site.

[0011] As shown in Figs. 2 and 3, the electric cutter device 30 is configured to rotate a disk-shaped blade 31 having a cutting edge on its outer periphery in one direction by a driving source 32 such as an electric motor. The blade 31 is provided so that a part of the cutting edge protrudes from a lower surface 33a of a base 33. The lower surface 33a of the base 33 is flat and extends in a direction perpendicular to the blade 31. A guide reference surface 33b is provided on an edge of the base 33 below the driving source 32 so as to be parallel to the rotation plane of the blade 31. In this electric cutter device 30, the lower surface 33a of the base 33 is opposed to the object to be cut, and the blade 31 is rotated from this state and moved relative to the object to be cut, thereby cutting the object.

[0012] The fence 20 to be cut in this embodiment has a surface material between the ends of upper and lower horizontal furring strips (frame materials) 21, as shown in Figures 4 and 5. The surface material is constructed by providing left and right vertical bones 22 between the horizontal furring strips 21, providing a backbone 23 between the middle parts of the horizontal furring strips 21, and bridging the backbone 23 between the left and right vertical bones 22 with multiple horizontal lattice members 24. The horizontal furring strips 21, vertical bones 22, backbone 23, and horizontal lattice members 24 are each made of a metal such as an aluminum alloy. As is clear from the figures, the horizontal furring strips 21 are constructed so that the dimension t1 along the thickness direction of the fence 20 is larger than the dimension t2 of the horizontal lattice members 24.

[0013] The panel cutting guide device 10 is configured with a slide guide 11 and a guide rail 12, as shown in Figs. 6 and 7. The slide guide 11 is an extrusion formed from a metal such as an aluminum alloy, and is configured with a mounting plate portion 11a, a support block portion 11b, a support plate portion 11c, and a clamp portion 11d. The mounting plate portion 11a is rectangular in shape with a length greater than the height dimension H (= the distance from the upper end surface of the upper horizontal furring strip 21 to the lower end surface of the lower horizontal furring strip 21) of the fence 20 to be cut. The support block portion 11b is hollow and rectangular in shape and protrudes downward from the lower surface of the mounting plate portion 11a. This support block portion 11b has a width approximately half that of the mounting plate portion 11a, is disposed to one side of the mounting plate portion 11a, and forms a positioning reference surface 11e for the slide guide 11. The support plate portion 11c protrudes downward from the other edge of the mounting plate portion 11a and is thicker than the mounting plate portion 11a. The protruding dimension of the support plate portion 11c from the lower surface of the mounting plate portion 11a is the same as that of the support block portion 11b. Between the support plate portion 11c and the support block portion 11b, a storage portion 11f is formed, which is approximately half the width of the mounting plate portion 11a. The clamp portion 11d is formed in a thin plate shape that is approximately perpendicular to the lower edge of the support plate portion 11c and extends in the opposite direction to the mounting plate portion 11a. The longitudinal dimensions of the support block portion 11b, the support plate portion 11c, and the clamp portion 11d are the same as those of the mounting plate portion 11a.

[0014] A plurality of grooves 11j are provided along the length of the upper surface (surface) 11g of the mounting plate portion 11a and the upper surface 11h of the clamp portion 11d, and a cushioning material 13 is provided on the lower surfaces of the support block portion 11b and the support plate portion 11c. The grooves 11j are minute and have a depth of, for example, about 1 / 4 of the plate thickness of the mounting plate portion 11a, a width and a pitch (distance from groove 11j to groove 11j) about the plate thickness of the mounting plate portion 11a, and are formed over the entire length of the mounting plate portion 11a and the clamp portion 11d. The grooves 11j of the mounting plate portion 11a are provided in a portion that is about 5 / 6 of the entire width from the edge on the side where the support block portion 11b is provided, and the grooves 11j of the clamp portion 11d are provided over the entire width. The cushioning material 13 is molded from soft resin and is attached to attachment grooves 11k provided in the support block portion 11b and the support plate portion 11c. The cushioning material 13 is provided over the entire length of the support block portion 11b, protruding downward from both side edges of the lower surface. The cushioning material 13 is provided over the entire length of the support plate portion 11c, protruding downward from the center of the lower surface.

[0015] The portion of the mounting plate 11a corresponding to the storage portion 11f has a plurality of slots 11m. The slots 11m are through holes extending in a direction perpendicular to the longitudinal direction of the mounting plate 11a, and are formed at positions that are approximately equally spaced from each other. Cover members 16 are attached to both end faces of the slide guide 11.

[0016] The guide rail 12 is a long member with a rectangular cross section formed from a metal such as an aluminum alloy, and has a length substantially equal to the overall length of the slide guide 11. The height h1 of the guide rail 12 is set to a dimension that does not contact the driving source 32 when the electric cutter device 30 is placed on the slide guide 11 via the base 33. In the illustrated example, the height h1 of the guide rail 12 is set to be smaller than the height dimension h2 of the guide reference surface 33b of the base 33, but is not necessarily limited to this. The guide rail 12 has shaft members 14 attached to portions corresponding to the long holes 11m of the mounting plate portion 11a when the guide rail 12 is disposed along the longitudinal direction of the slide guide 11. The shaft members 14 are cylindrical with an outer diameter that allows them to be inserted into the long holes 11m, and are provided so as to protrude from the bottom surface of the guide rail 12. The portion of the shaft member 14 that protrudes from the bottom surface of the guide rail 12 has a screw groove 14a on the peripheral surface, to which a nut member 15 can be screwed. The dimension of the shaft member 14 along the axial direction is set so that when it is inserted through the long hole 11m from the upper surface 11g of the mounting plate portion 11a, it does not protrude downward from the lower surface of the support block portion 11b.

[0017] The guide rail 12 having the above configuration is held in a state of protruding upward from the upper surface 11g of the mounting plate portion 11a by inserting the shaft members 14 into the long holes 11m and then screwing the nut members 15 onto the individual shaft members 14 in the accommodation portion 11f. The side surface of the guide rail 12 located on the mounting block portion 11b side of the slide guide 11 forms a linear guide surface 12a that is substantially perpendicular to the upper surface 11g of the mounting plate portion 11a. The position of this guide surface 12a can be changed as appropriate by changing the insertion position of the shaft members 14 relative to the long holes 11m.

[0018] When cutting the fence 20 using the above-mentioned panel cutting guide device 10, first, the sleepers 40 are placed on the ground. The sleepers 40 are placed in portions corresponding to both sides of the fence 20 before cutting, and in portions adjacent to the cutting position.

[0019] Next, the fence 20 is placed on the upper surface of the sleeper 40, and a marking line L1 is made at the cutting position of the fence 20.

[0020] Next, the panel cutting guide device 10 is placed on the top surface of the fence 20 with the positioning reference surface 11e of the slide guide 11 parallel to the scribe line L1. After that, the fence 20 is clamped by the clamper 41 via the clamp portion 11d, thereby preventing relative movement between the slide guide 11 and the fence 20. The clamper 41 used is a clip type that protrudes upward below the top surface of the guide rail 12 when the clamp portion 11d and the fence 20 are clamped.

[0021] At this time, by arranging the slide guide 11 so as to span the horizontal furring strips 21 of the fence 20, the slide guide 11 will not come into contact with the horizontal lattice material 24 of the fence 20. In addition, a cushioning material 13 is provided on the underside of the slide guide 11. Therefore, there is no risk of the slide guide 11 coming into direct contact with the horizontal furring strips 21 on which it is installed. Therefore, there is no need to provide protective covering to the fence 20 prior to cutting it, making it possible to facilitate the above-mentioned work.

[0022] Next, the electric cutter device 30 is placed on the upper surface of the slide guide 11 via the base 33, the position of the blade 31 is aligned with the marking line L1, and the guide surface 12a of the guide rail 12 is abutted against the guide reference surface 33b of the base 33, and the nut member 15 is screwed onto the shaft member 14 to fix the position of the guide rail 12.

[0023] After the slide guide 11 and guide rail 12 are installed on the fence 20 as described above, the electric cutter device 30 is placed on the slide guide 11 with the lower surface 33a of the base 33 abutting against the upper surface 11g of the mounting plate portion 11a. From this state, the electric cutter device 30 is driven and moved along the longitudinal direction while the guide reference surface 33b of the base 33 abuts against the guide surface 12a of the guide rail 12, whereby the fence 20 can be cut along the scribe line L1.

[0024] During this time, according to the panel cutting guide device 10, the base 33 of the electric cutter device 30 moves on the upper surface 11g of the mounting plate portion 11a, so that regardless of whether there is a step d between the horizontal furring strips 21 and the horizontal lattice material 24, the guide reference surface 33b of the base 33 can always be brought into contact with the guide surface 12a of the guide rail 12, making it possible to accurately cut the fence 20. Moreover, because the base 33 does not directly contact the fence 20, there is no concern that the fence 20 will be damaged, such as scratched.

[0025] In the above embodiment, the fence 20 having a plurality of horizontal lattice members 24 between the ends of the upper and lower horizontal furring strips 21 is the object to be cut, but the present invention is not limited to this, and can also be applied to a panel having other surface materials such as a panel or net between the upper and lower frame materials. In this case, it is not necessarily limited to a case where there is a step between the frame material and the surface material. In addition, the electric cutter device 30 to be applied is exemplified as one having a disk-shaped blade 31, but is not limited to this. For example, it may be one that cuts the object by reciprocating a blade extending linearly.

[0026] Furthermore, in the above-mentioned embodiment, the groove 11j is provided on the upper surface 11g of the mounting plate portion 11a, so that the operation of sliding the base 33 of the electric cutter device 30 can be performed smoothly, but the groove 11j does not necessarily have to be provided. The low-friction treatment for smoothing the sliding of the base 33 is not necessarily limited to providing the groove 11j, and for example, a low-friction sheet may be attached to the upper surface 11g of the mounting plate portion 11a. Furthermore, the guide rail 12 is arranged to be movable relative to the slide guide 11, but the slide guide 11 and the guide rail 12 can be provided integrally. In the above-mentioned embodiment, when the guide rail is arranged to be movable relative to the slide guide, a long hole 11m is provided in a direction perpendicular to the guide surface 12a, and the guide rail is moved along the long hole 11m, but it is not necessarily required to move in a direction perpendicular to the guide surface 12a, and it is sufficient if the direction intersects the guide surface 12a.

[0027] As described above, the panel cutting guide device of the present invention is a panel cutting guide device that is applied when a panel having a face material between two frame materials is cut by an electric cutter device having a blade protruding from a base, and is characterized in that it comprises a slide guide that is arranged across the two frame materials and on which the base is slidably placed on its front surface with the blade protruding from the back surface, and a guide rail that protrudes from the front surface of the slide guide and abuts against the base placed on the slide guide. According to this invention, the base of the electric cutter device is placed on the surface of the slide guide that is placed across the frame material, so even if there is a step between the frame material and the surface material, the electric cutter device can be moved linearly along the guide rail, making it possible to cut the panel accurately. Moreover, since there is no direct contact between the panel and the base of the electric cutter device, there is no need to protect the panel prior to the cutting operation, making it easier to cut the panel.

[0028] The present invention is also characterized in that, in the above-mentioned panel cutting guide device, the guide rail abuts against the base via a guide surface extending in a straight line, and is arranged to be movable relative to the slide guide along a direction intersecting the guide surface. According to this invention, even when an electric cutter device in which the mutual distance between the side surface of the base and the blade varies is applied, the panel can be accurately cut by moving the guide member relative to the slide guide.

[0029] The present invention is also characterized in that, in the above-mentioned panel cutting guide device, the slide guide is provided with a long hole extending along a direction intersecting the guide surface, the guide rail is provided with a shaft member having a threaded groove on its circumferential surface and is inserted into the back side of the slide guide through the long hole, and the shaft member is provided with a nut member for clamping the slide guide between the shaft member and the guide rail. According to this invention, the guide rail can be moved by loosening the nut member, and the position of the guide rail can be maintained by screwing the nut member.

[0030] Furthermore, the present invention is characterized in that in the above-mentioned panel cutting guide device, a housing portion for housing the nut member is provided on a rear surface of the slide guide. According to this invention, since the nut member does not protrude from the rear surface of the slide guide, the slide guide can be disposed at a desired position regardless of the position of the nut member.

[0031] Furthermore, the present invention is characterized in that in the above-mentioned panel cutting guide device, a cushioning material is provided on the rear surface of the slide guide at least in a portion that abuts against the frame material. According to this invention, it is not necessary to provide protective covering for the frame material, and there is no risk of the frame material and the slide guide becoming loose when the electric cutter device is operated.

[0032] Further, according to the present invention, in the above-mentioned panel cutting guide device, a thin plate-shaped clamp portion is provided on the slide guide. According to this invention, by clamping the slide guide to the panel via the clamp portion, it is possible to more reliably prevent the slide guide from shifting out of position.

[0033] Further, the present invention is characterized in that in the above-mentioned panel cutting guide device, a surface of the slide guide is subjected to a low-friction treatment. According to this invention, the operation of moving the electric cutter device becomes smooth, and the panel cutting work can be facilitated. [Explanation of symbols]
