Definitions

  • the present invention relates to a cutting tool for cutting a plate made of a reconstituted material.
  • plaster, cement or ceramic tiles are used as building or finishing elements, fiber cement cladding boards, medium density cellulosic fiber boards as slabs of coating or finishing and laminated sheets as elements of a floating floor.
  • the tool in question must also meet other requirements: the tool must be simple to use, easy to stabilize on a floor, especially on more or less irregular soil such as soil outside the workshop. In addition, it would be useful if the tool is not limited to a right-angle cut and has a means to prevent the plate from being driven out by the blade of the cutting tool.
  • a device for cutting rods electrical son which comprises a support base, a blade shaped knife steel, which is mounted movable on the base and bosses against which the stick is supported during the cutting, the cutting angle being 45 °.
  • the known apparatus has the disadvantage that it does not cut plates of a reconstituted material, whose characteristics are the hardness and thickness.
  • the object of the invention is therefore to provide a cutting tool for cutting a plate made of a reconstituted material, meeting the various requirements mentioned above.
  • the object of the invention is achieved with a cutting tool according to claim 1.
  • the flat cutting blade performs, in cooperation with the edges of the slot of the base, a double shear having the effect that the blade does not penetrate, during cutting, in the usual way in the material of the plate to be cut, but removes a strip of material from the plate.
  • the width of the band corresponds substantially to that of the blade.
  • the plate made of a reconstituted material is not deformed, since it is supported on both sides of the blade, by the two parts of the base located on one side and the other of the slot of the basement.
  • the cutting plate is retained on the base so that it can not escape in front of the descending blade during the entire cut through the stop.
  • the Figures 1 to 5 show a cutting tool according to a first embodiment of the invention for cutting a plate made of a reconstituted material.
  • the tool comprises a base 1 and a blade 2 mounted movably on a support 3 attached to the base 1.
  • the blade 2 is pivotally mounted about an axis 4, which moves the blade 2 between an open position to receive, between the support 3 and the blade 2, a plate made of a reconstituted material to be cut, and a closed position at the end of a cut.
  • the blade 2 encloses with the support 3 an angle AC.
  • the blade 2 is formed with a back 21, a cutting edge 22 flat and curved and a step 23. While the function of the back 21 and the cutting edge 22 does not require explanation, it should be noted that the step 23 allows to limit the stroke of the blade 2 to the open position. The open position of the blade 2 is reached when the step 23 bears on the support 3.
  • the support 3 is provided with a slot 5 shaped to receive the blade 2 during cutting, and a transverse stop 6 for retaining the plate to be cut during cutting.
  • the cutting plate is placed on the support 3 and is pressed against the transverse stop 6.
  • the transverse stop 6 can succeed the double mission assigned to it, that is to say prevent the plate is driven by the blade 2 in the cutting direction and maintain the plate in an angularly stable position to allow to obtain a straight cut, the transverse stop 6 must be wide.
  • the width of the transverse stop 6 corresponds approximately to the length of the slot 5, preferably to the effective length LF of the slot 5.
  • the cutting edge 22 of the blade 2 is advantageously obtained by laser cutting. This way of producing the blade 2 essentially brings two advantages. The first is the possibility of obtaining in a single stage of manufacture a sharp edge and in any previously determined form. This is all the more interesting as the cutting edge 22 is flat, as shown in FIG. figure 4 , and therefore does not need to be sharpened.
  • the blade 2 cooperates with the slot 5, and more precisely with the longitudinal edges of the slot, in the manner of two shears placed in parallel.
  • each of the two longitudinal edges of the cutting edge 22 of the blade 2 forms, with the corresponding longitudinal edge of the slot 5, a shear.
  • the two shears thus loose, by simultaneous shearing during the descent of the blade 2, a corresponding half of what is removed, as the cutting progresses, as a strip of the material of which the plate to be cut is made.
  • the width BF of the slot 5 is greater than the width BL of the blade 2
  • the difference between the width BF of the slot 5 and the width BL of the blade 2 is determined as a function of the thickness of the plates to be cut. For example, to cut plates having a thickness of about 7 mm, the difference between the two widths BF and BL is about 3 mm.
  • the curvature of the blade 2 is determined so that in any instantaneous position of the blade during cutting, the angle AC enclosed between the support 3 and the blade 2 is at least approximately constant.
  • the blade 2 is provided with a handle 7 connected to the blade 2 by an arm 8 forming a lever.
  • a passage 10 of the blade 2 to the arm 8 is shaped to bear against the stop 6, at the end of cutting, and thus limit the stroke of the blade 2 to its closed position. The closed position of the blade 2 is reached when the passage 10 bears on the abutment 6.
  • the handle 7 is offset relative to the back 21 of the blade 2 so that the handle 7 is located at the end of a cut, approximately at the same level as the slot 5 or at a level below it.
  • the figure 1 represents this arrangement using dashed ND and NF lines.
  • the line ND is the extension of the back 21 of the blade 2 and the line NF is the extension of the slot 5.
  • the handle 7 of the blade 2 is offset relative to the line ND, and thus with respect to the back 21 of the blade 2, by an angle large enough to obtain the following two results.
  • the second result is represented on the figure 3 at the beginning of a cut, preferably also when the blade 2 is in the open position, the handle 7 is located, relative to the vertical VD from a marking point on the slot 5 the beginning of the cut, on the side The abutment 6.
  • VD vertical
  • the floor or any other bottom on which the tool will be placed will not necessarily be straight or horizontal everywhere. It is thus easy to design situations where the tool will be placed on a background resistant to the forces developed during cutting, but which can not ensure a horizontal position to the tool. Accordingly, to facilitate the initiation of cutting, it is recommended that the handle 7 is already at the beginning of cutting in a position allowing a person using the tool to use mainly its weight to move the blade 2 instead of having to pull the blade toward her.
  • the base 1 of the tool according to the invention is extended in the cutting direction by a foot 9 ensuring the stability of the tool in the cutting direction and in a direction transverse thereto.
  • the foot 9 is constituted by a T-section, as shown in FIGS. Figures 1 to 3 .
  • An advantageous characteristic of the foot 9, regardless of its shape, is to allow the user of the tool to put his foot on the foot 9 of the tool and to hold the tool during the entire cutting in a simple manner and safe while leaving the user's hands free for handling the blade 2.
  • the figure 5 shows the tool according to the first embodiment of the invention, shown in the Figures 1 to 4 , with a first cutting accessory.
  • the first cutting accessory comprises a wedge 62 shaped to be fixed on an edge 61 of the abutment 6, the edge 61 being opposite the blade 2.
  • the wedge 62 is moreover represented twice, referenced respectively 62 and 62A, to show that it is reversible.
  • the invention proposes the shim 62 which is provided with an oblong hole 63 to be fixed on the stop 6 by a bolt 64.
  • the oblong hole 63 makes it possible to fix the shim, as shim 62 on one side of the abutment 6 or as wedge 62A on the other side of the abutment 6, in different positions along the edge 61 of the abutment 6.
  • the plate to be cut then takes resting on a central notch 60 of the abutment 6 and on a rounded corner 65 of the shim 62. It is easily understood that the more the shim 62 is brought closer to the notch 60 plus the cut deviates from a cut at right angles.
  • the rounded shape of the wedge 65 of the spacer 62 avoids damaging the field of the plate to be cut.
  • the tool in order to be able to use the tool of the invention also for cuts with angles very different from the right angle, the tool is equipped, as a variant of the stop 6 mounted fixed at right angles to the 2, a transverse stop 106 mounted movably on the support 3 so as to be fixed in different angular positions according to the desired cutting angle and to different distances from the axis 4 of the blade 2 according to the dimensions of the plate to be cut.
  • the transverse stop 106 comprises a guide rod 111 and a bolt 112, both crossing the transverse stop 106 and protruding therefrom on both sides of the abutment.
  • the guide rod 111 serves only to guide the abutment 106 during its movements along the slot 5 and therefore does not need to be very long
  • the bolt 112 serves both to guide the transverse stop 106 during its movements along the slot 5 and together with a curved opening 114 formed in the abutment 106, during the adjustment of a cutting angle, and to fix it in a chosen position.
  • the bolt 112 comprises a screw long enough for its head to slide and bear on the inner face, on either side of the slot 5, the support 3 and so that the body of the screw can cross the slot 5 and the transverse stop 106 and protrude from the upper face of the latter over a sufficient length to be able to place the nut.
  • the transverse stop 106 is equipped with a rule 120, made in the form of a T and mounted parallel to the edge 61 of the transverse stop 106 opposite the blade 2.
  • the rule 120 is guided on the transverse stop 106 by lugs 115 protruding from both faces of the abutment 106 and is fixed on the transverse stop 106 by a flange 113 which itself is pressed on the ruler and the abutment by the bolt 112 when the It's tight.
  • the rule 120 whose T-shape is obtained by integrating a cross-member 121 having two opposite ends 122, 123, serves as a lateral stop and support for the reconstituted material to be cut, when the material is cut at an angle other than 90 °. Because in such a case, the orientation of the transverse stop 106 is at the origin of a decomposition of the thrust of the blade in a longitudinal component according to the orientation of the slot 5 and a transverse component to the right or to the left of the slot 5 according to the orientation of the edge 61 of the abutment 106. And it is this transverse component that this is countered by the presence of a lateral stop 122 or 123, depending on whether the rule 120 is oriented to the right as shown in FIG. figure 6 or in the opposite direction.
  • the arrangement that the guide rod 111, the bolt 112 and the lugs 115 protrude from both sides of the transverse stop 106 allows the transverse stop 106 to be used both upwards and downwards. This is particularly advantageous when the curved opening 114 is not symmetrical in order to make possible a wide range of cutting angles without weakening the transverse flange 106 by an opening 114 which is too long.
  • the transverse stop 106 is provided on its face 61, two notches 116, 117 asymmetrical relative to each other .
  • the figure 7 shows a tool that differs from the tool according to the Figures 1 to 6 essentially by a blade 200 with a less curved cutting edge and whose shape has been determined so as to give the blade 200 an opening position different from the open position of the blade 2 of the first embodiment and so as to incorporating on the cutting edge a stop 203 in the blade 200.
  • the characteristics of the tool which are identical to those of the first embodiment bear the same reference numbers.
  • the blade 200 is formed with a back 201, a cutting edge 202 flat but less curved than the blade 2, a first stop 203 formed between the cutting edge 202 and the axis 4 by which the blade 200 is mounted on the support 3, and a second stop 204 formed between the blade 200 and the arm 8. While the function of the back 21 and the cutting edge 22 do not require explanation, it It is necessary to specify the functions of the two stops 203 and 204.
  • the blade 200 can be formed only with the first stop 203 or both with the first stop 203 and the second stop 204, according to the selected embodiment of the second embodiment of the tool of the invention.
  • the blade 200 differs from the blade 2 of the first embodiment more particularly because the beginning of the cutting edge 202 is spaced from the support 3 and the slot 5 of the support 3 when the blade 200 is in the open position. This is obtained by a shape distinct from that of the two ends of the blade through which the axis 4 passes. This end is shaped to constitute both the point of pivoting of the blade, an element of raising of the blade with respect to the axis 4 when the blade is in the open position and at the beginning of the cutting phase, and a stop 203 against which a cutting plate is pressed.
  • the blade 200 flushes the plate that it must cut, because of the angle that the blade encloses with the support 3.
  • the blade 200 enclosing with the support 3 an angle much smaller than the blade 2 and this angle being at the beginning of the cut facing the axis 4, the vertical component of the support exerted by the blade 200 is from the beginning of the cutting sufficiently strong to immobilize the plate.
  • the blade tends to drive the plate towards the axis 4. It is therefore unnecessary to provide a stop 206 on the support 3.
  • the stop 203 of the blade 200 can not ensure accurate positioning of the plate. It is therefore necessary to use a stop 206 mounted movably by means of a bolt 205, this stop essentially corresponding to the stop 106 of the first embodiment.
  • the blade 200 has a notch 204 which bears on the bolt 205 when the blade 200 has reached the closed position.
  • the figure 8 shows a tool according to a third embodiment of the invention.
  • This tool corresponds to that of the second embodiment (see figure 6 ) to the extent that the tool comprises a base 1 and a blade 2 mounted movably on a support 3 attached to the base 1.
  • the blade 2 is pivotally mounted about the axis 4 so that it can be moved between an open position to receive a cutting plate and a closed position at the end of a cut.
  • the support 3 is provided with a slot 5 shaped to receive the blade 2 during cutting.
  • the tool according to the third embodiment of the invention is shown with a tray 330 for collecting chips and cutting debris, and a foot 370 for supporting the free end of a plate P to be cut, for example a floorboard or plinth.
  • the tray 330 is intended to receive the particles and pieces that are detached from the plate to be cut.
  • the tray 330 comprises a bottom 331, two longitudinal flanges 332, 333 and two transverse flanges 334, 335.
  • the tray 330 is advantageously formed from a single sheet by folding with a width such that the base 1 can to be inserted without significant play of the cross of the base 1. So that the length of the tray 330 can be limited approximately to the length of the blade 2 and in particular without taking into account the length of the base 1 and its extension 339 described below, the transverse flange 335 is provided with a cutout for inserting the base 1.
  • the tray 330 can be made integral with the base 1 of the tool of the invention, so as to be an integral part of the tool, or separately as if it were an accessory of the tool. Without departing from the principle of the present invention, the tray 330 may also be part, as an integral part or accessory, of one or the other of the first to third embodiments of the tool of the invention .
  • the foot 370 is intended to support, together with the support 3, a plate P to be cut. More precisely, the foot 370 is intended to support the free end of the plate P and to maintain it at a level H greater than the height h of the upper face of the support 3. Thanks to this arrangement of the invention, the plate P will be held in such a way as to obtain a slightly beveled edge and thus compensate for the inevitable tearing at the edge of the rear face of the plate.
  • the foot 370 can be made as an integral part of the tool of the invention, moreover of any one of the first to third embodiments of the invention, or as an accessory part.
  • the variant of separate part has the advantage that the foot 370 can be placed at any useful distance from the support 3 of the tool, without limitation by a connecting rod, even adjustable in distance, or by any other element by which the foot would be mounted integral with the base 1 or the support 3 of the tool of the invention.
  • the foot 370 When the foot 370 is made as a separate part, it advantageously comprises a hole 371 by which it can be bolted, during transport of the tool, to the blade 2 provided for this purpose with a hole T (see figure 5 ).
  • the tool according to the third embodiment differs from that according to the second embodiment in that the base 1 is extended in the cutting direction by a foot 339 in the form of a rectangular straight profile ensuring the stability of the tool in the cutting direction.
  • the pedestal 1 and pedestal assembly 339 thus forms a three-point, not four-point base as in the first and second embodiments of the invention.
  • a three-point base can provide better stability than a four-point base when the support or ground on which the tool is laid for cutting is very irregular.
  • the tool according to the third embodiment is equipped, as a variant of the abutment 6 mounted fixed at right angles to the blade 2 in the first and second embodiments, a transverse stop 306 mounted movably on the support 3 so as to be fixed in different angular positions according to the desired cutting angle.
  • the transverse stop 306 can not be mounted at different distances from the axis 4 of the blade 2.
  • the variable distance of the transverse stop is realized in the third embodiment by a third accessory 350 described below.
  • the transverse stop 306 comprises a graduated support 307 secured to the support 3, a plate 308 with a straight edge 309 forming a transverse stop and a clamping mechanism 310 for stopping the plate 308 in different angular positions.

  • the graduated support 307 is a part made in the image of a protractor, it is that is to say, it has a graduation to the angular degree near disposed along a curved edge. This graduation covers a range of about fifty degrees on each side of the median of the slot 5.
  • the support 307 being secured to the support 3, the zero degree marking therefore indicates the orientation of the cut when it comes to making a rectangular cut.
  • the plate 308 forming a stop is provided, to be angularly displaceable, a slot 311 in an arc whose length is chosen so as to move this plate 308 over the entire range of the graduation of the support 307.
  • the tool comprises a toggle mechanism 310 shaped to be able to clamp and loosen the plate 308 relative to the support 307 by means of a lever 312 and a lever axis 313 set in axial translation by the action of the lever.
  • the plate 308 is pressed against the support 307 when the lever 312 of the clamping mechanism 310 is lowered and, as shown in FIG. figure 11 , the plate 308 is loosened from the support 307 when the lever 312 is raised.
  • the clamping mechanism of the tool according to the third embodiment of the invention comprises, in addition to the lever 312 and the shaft 313, a washer 314 and a brake nut 315.
  • the mechanism 310 is mounted below the support 307. so that the shaft 313 passes through both the support 307 through a through hole and the plate 308 abutting the slot 311 and protrudes from the plate 308 upwards for a sufficient length to thread the washer 314 and screw the brake nut 315 on the threaded shaft 313.
  • the braking character of the thread of the nut 315 is necessary in order to be able to adjust the position of the nut 315 on the threaded shaft 313 and thereby the clamping force exerted on the when the lever 312 is lowered and where the threaded shaft assembly 313, washer 314 and nut 315 pulls the plate 308 downwards and thus closes it against the graduated support 307.
  • the figure 10 shows the clamping mechanism of the tool according to the third embodiment in the clamping position. And it is more particularly seen that the plate 308 is well supported on the graduated support 307 and there is also recognized a traditional mechanism of knee lever by which the lever 312 is connected to the axis 313 to be able to move it in axial translation.
  • the figure 11 shows the clamping mechanism of the tool according to the third embodiment in the release position. We see more particularly on
  • the axis 313 comprises a lower part, seen in the direction of assembly in the tool of the invention, with a first diameter and a threaded upper part with a second diameter, smaller than the first.
  • the difference between the first diameter and the second diameter is chosen so that a circular shoulder 316 forming the transition between the lower part and the upper part of the axis 313 is sufficiently large to be able to carry the plate 308.
  • the axis 313 When, instead, the lever 312 is in the fully raised position, the axis 313 is in its upper position, as shown in FIG. figure 12 and the lower portion of the shaft 313 protrudes from the graduated support 307 by a height sufficient to maintain the plate 308 elevated relative to the graduated support 307 so that a displacement angular plate 308 is easily possible.
  • the plate 308 is fixed on the upper part of the axis 313 so that it is pushed upwards by the circular shoulder 316 of the axis 313 when it is a question of separating the graduated support 307 and the plate 308.
  • the plate 308 Conversely, the plate 308 is pulled down to bear on the graduated support 307 by the washer 314 and the nut 315 when the axis 313 is axially displaced towards the low.
  • the graduated support 307 and the plate 308 are provided, on each of the two facing faces, with a succession of notches arranged in an arc of a circle and covering the range of orientation provided. Thanks to these notches 317 on the graduated support 307 and the notches 318 made on the plate 308, and thanks to the fine notch division of these two series of complementary notches, it is possible to adjust the orientation of the transverse stop 309 at least to the nearest degree, or even to the nearest half degree, according to the fineness of the notches.
  • the reading of the orientation of the transverse stop 309 on the graduation 319 of the graduated support 307 is facilitated by means of an index 320 projecting from the edge of the plate 308 as shown by FIGS. figures 11 and 13 .
  • FIGS 14 and 15 show, as a first embodiment of the tool according to the third embodiment of the invention, a rule 340.
  • the cutting tool according to the second embodiment of the invention comprises a rule 120 disposed parallel to the transverse stop 61 so as to prevent a cutting plate from being driven by the blade during cutting as explained above.
  • the cutting device of the invention comprises a rule 340 comprising a rod 341 and a stop 342.
  • the rod 341 is advantageously a solid body or a hollow cylindrical element and in any case of circular cross section.
  • the stop 342 is a stepped plate mounted transversely to the rod 341 and having a cut-out shape according to the dimensions of the plate 308. The cuts are made so that the stop 342 can be brought as close as possible to the blade 2.
  • the rule 340 is shaped to be fixed on the plate 308 by means of a parallelepiped blocking element 343 mounted integral with the plate 308 and having a cylindrical passage 344 in which the rule 340 is slidably inserted.
  • the parallelepipedic locking element 343 comprises at least one, preferably two or, as shown in FIG. figure 14 three locking screws 346.
  • the rule 340 is inserted in the locking element 343 respectively by the right side or by the left side so that that the stop 342 is, relative to the graduation 319 of the graduated support 307, on the opposite side to the graduation portion on which is placed the index 320.
  • the rule 340 forms a support for the plate to cut so as to prevent the plate from laterally backwards due to the thrust exerted by the blade 2.
  • the figure 15 shows also that the locking element 343 is advantageously shaped to serve as a stop for the blade 2. Indeed, as shown on the figure 15 , the blade 2 bears on the fixing element 343 when it is at the end of cutting.
  • the locking of the rod 341 of the rule 340 in a chosen lateral position is carried out using the three screws 346 that do not protrude from the upper horizontal face of the fastener 343 when tightened.
  • the tightening and loosening of the three screws 346 are performed using an Allen wrench 345 or any other tool adapted to the shape of the screw heads.
  • an Allen wrench 345 or any other tool adapted to the shape of the screw heads.
  • To store the key 345 one can use for example one or the other of the two orifices 347, 348 made in the plate 308.
  • FIGS. 16 and 17 show in detail a second variant embodiment of the cutting tool of the invention, provided more particularly for cutting blades of smaller width.
  • the second embodiment provides not only a variable orientation of the transverse stop, but also its displacement along the support 3 in order to be able to approach or move more or less the transverse stop relative to the pivot axis 4 of the
  • the third embodiment of the tool of the invention does not offer this possibility.
  • the third embodiment provides a third cutting accessory in the form of a plate 350 forming an auxiliary transverse stop 351.
  • the plate 350 comprises two lateral flanges 352, 353 and a transverse flange 351 forming at the same time transverse stop .
  • the plate 350 further comprises a slot 354 extending over most of the length of the plate and thus providing the space required for the blade 2 to be able to penetrate the slot 5 of the support 3.
  • the plate 350 is intended to to be placed on the plate 308 as shown in figure 16 and comprises for this purpose a rectangular cut 355 whose dimensions correspond to that of the fastening element 343.
  • the plate 350 For fixing the plate 350 on the plate 308, the plate 350 comprises two orifices 356, 357 arranged to be superimposed on the orifices 346, 347 of the plate 308 when the plate 350 is to be mounted on the plate 308.
  • the actual fixing of the plate 350 is made with screws and nuts passing respectively through the holes 346, 357 and the holes 347, 356.
  • the figure 17 shows that the holes 356, 357 are advantageously made as square holes which allows to introduce stove bolts facilitating tightening nuts. It goes without saying that any other type of screw / nut assembly can also be used without departing from the principle of the present invention.
  • the figure 18 represents a third variant embodiment of the third embodiment of the tool of the invention, namely a variant of the parallelepiped element 343 (see Figures 14, 15 ) of the third embodiment of the invention by means of which a rule 340 is fixed on the tool of the invention.
