  Embodiments of the present invention will be described below with reference to the accompanying drawings. In the accompanying drawings, the same reference numerals are assigned to the same or similar components.

  FIG. 1 is a schematic perspective view of a floor material cutting machine 1 according to the present invention. For the sake of clarity, in FIG. 1, only one lead line for the reference symbol is provided for each of the five components. FIG. 2 is a side view of the floor material cutting machine 1 in which a part of the handle 5 and the main body 2 is omitted.

  The floor material cutting machine 1 includes a main body 2, a cutting blade 3 (see FIG. 2), a wheel 4, a handle 5, a weight 6, and a cutting depth adjusting mechanism. The cutting blade 3, the wheel 4, the handle 5 and the weight 6 are fixed to the main body 2.

  First, a method of using the floor material cutting machine 1 will be briefly described. The floor material cutting machine 1 is disposed on the floor material 100 so as to cut the floor material 100 attached on the floor 101. The floor 101 is, for example, concrete. The flooring 100 is made of resin or rubber, and is, for example, a tile member or sheet member such as a vinyl chloride tile, a urethane sheet, or a synthetic resin sheet. After the placement, when the operator grips the handle 5 and pulls the main body 2 with the handle 5 in the direction of arrow A, the wheel 4 rolls on the flooring 100, so that the main body 2 and the cutting blade 3 It can be moved with. At this time, the cutting blade 3 in contact with the flooring material 100 cuts the flooring material 100. The weight 6 increases the cutting depth of the cutting blade 3 with respect to the floor material 100 by increasing the load applied to the cutting blade 3. However, the floor material cutting machine 1 may apply a load to the cutting blade 3 only by the weight of the main body 2 without providing the weight 6. The operator reciprocates the floor material 100 over a predetermined range while pulling the floor material cutting machine 1, and then tears the floor material 100 manually along the remaining straight cutting traces to the floor 101. Peel from.

  Next, the configuration of the floor material cutting machine 1 will be described. The main body 2 of the floor material cutting machine 1 includes a front shaft 21 and a rear shaft 22 extending in parallel with each other, and a plurality of plates 23 extending between the front shaft 21 and the rear shaft 22 perpendicular to the axial direction thereof. And a plurality of connecting plates 24 connected to the front end of the plate 23, and a plurality of front end portions 25 (see FIG. 2) connected to the connecting plate 24 by connecting screws 80 and through which the front shaft 21 passes. , Two wheel fixing portions 26 (see FIG. 2) fixed to the lower portion of the front end portion 25 arranged at both ends, and a tail portion 27 connected to the rear shaft 22. The number of the connecting plate 24, the plate 23 connected to each other via the connecting plate 24, and the front end portion 25 are equal. The front shaft 21 and the rear shaft 22 connect the assemblies including the plate 23, the connecting plate 24, and the front end portion 25 to each other at both ends in the longitudinal direction of each assembly. The main body 2 is made of metal, and the connection points are typically connected by welding. In the present specification, the wheel 4 side of the floor material cutting machine 1 is defined as the “front” side, and the tail 27 side of the floor material cutting machine 1 is defined as the “rear” side.

  Each plate 23 extends substantially parallel to each other, and the distance between the plates 23 is equal. Since the cutting blade 3 is attached to the lower part of the plate 23, this interval determines the interval between the linear cutting traces left on the floor material 100 by the cutting blade 3. This interval is preferably an interval at which the operator can manually tear the flooring material 100 along the cut mark and peel it off the floor 101, for example, about 50 to 150 mm. Moreover, when the number of the cutting blades 3 attached to the plate 23 increases, the force required for the movement of the floor material cutting machine 1 increases due to the frictional force between the cutting blade 3 and the floor material 100. For this reason, it is desirable that the number of the plates 23 and the cutting blades 3 is five in order to enable the movement of the floor material cutting machine 1 by human power while leaving many cutting traces in one operation. In this case, the five cutting blades 3 are spaced apart in the horizontal direction with respect to the flooring 100 and in the direction perpendicular to the traveling direction A. In addition, the force required for the movement of the floor material cutting machine 1 can be reduced by reducing the number of the cutting blades 3 attached to the plate 23. If the interval between the plates 23 is 50 mm, the cutting trace interval can be changed to 200 mm by attaching the cutting blade 3 only to the two plates 23 at both ends. Other combinations such as attaching the cutting blade 3 only to the two plates 23 adjacent to both ends are also possible.

  The tail portion 27 extends substantially in parallel to the axis of the rear shaft 22 (and the front shaft 21), and extends substantially perpendicular to the axis of the rear shaft 22 to connect to the rear shaft 22. It consists of two connections 272. The tail 27 partially contributes to applying a load to the cutting blade 3. Further, when the flooring material 100 is cut by the cutting blade 3, the flooring material 100 that is usually stuck to the floor 101 by the adhesive even after cutting may partially lift from the floor 101. The cutting depth by the cutting blade 3 can be changed. In order to prevent this, the tail portion 27 also acts to press the floor material 100 in the already cut range when the cutting blade 3 cuts the floor material 100.

  As shown in FIG. 2, the wheel 4 is rotatably fixed to the wheel fixing portion 26 of the main body 2 so as to come into contact with the flooring material 100 when the flooring material cutting machine 1 is disposed on the flooring material 100. The main body 2 and the cutting blade 3 are configured to move. The wheel 4 is configured such that the rolling direction is substantially parallel to the longitudinal direction of the plate 23. As described above, since the wheel fixing portion 26 is fixed to the front end portion 25 with the screw 81, the wheel 4 cannot rotate in a plane parallel to the flooring 100 and rolls linearly. In the example shown in FIG. 1, the wheel fixing portions 26 and the wheels 4 are provided one by one below the front end portions 25 at both ends, but the number and positions of the wheel fixing portions 26 and the wheels 4 are not limited thereto. Absent.

  The cutting blade 3 is fixed to the main body 2 so as to come into contact with the flooring material 100 when the flooring material cutting machine 1 is disposed on the flooring material 100. More specifically, as shown in FIG. 2, the cutting blade 3 is fixed to the lower portion of the plate 23 with a mounting screw 83 at a position closer to the rear side than the front side of the plate 23. At this time, the cutting blade 3 is fixed so that the direction of the linear cutting trace left on the flooring 100 is substantially parallel to the direction in which the wheel 4 rolls, that is, the longitudinal direction of the plate 23. Further, in order to prevent cutting waste from clogging between the cutting blade 3 and the mounting screw 83, the cutting blade 3 is fixed so that the tip of the blade is separated from the mounting screw 83 by a predetermined distance.

  4 and 5 show a front view and a side view of the cutting blade 3, respectively. Typically, the cutting blade 3 is made of stainless steel and is a U-groove cutter having a U-shaped cross section as shown in FIG. For this reason, since the flooring material 100 is cut into a U-shaped cross section by the cutting blade 3, the operator easily tears the flooring material 100 along the cutting trace in which the flooring material 100 is thinned by the cutting. Can be peeled off. The width and height of the U groove are, for example, about 3 mm and about 2 mm. For this reason, the operator can visually recognize the cutting trace clearly because the cutting trace has a line width of about 3 mm. This facilitates the peeling work of the flooring 100 after cutting.

  The long hole 31, the circular hole 32, and the semicircular 33 notch 33 of the cutting blade 3 shown in FIG. 4 indicate the position and angle of the cutting blade 3 with respect to the plate 23 when the cutting blade 3 is attached to the plate 23. Used to determine. For example, in a state where a cylindrical projection provided on the mounting surface of the plate 23 is inserted into the long hole 31 of the cutting blade 3, the circular hole 32 of the cutting blade 3 is aligned with the position of the female screw hole 84 in the plate 23, The position and angle of the cutting blade 3 with respect to the plate 23 are determined by tightening the mounting screw 83 through the circular hole 32. The mounting angle of the cutting blade 3 with respect to the plate 23 is changed by providing a plurality of positioning projections on the mounting surface of the plate 23 and combining these projections with the long holes 31, the circular holes 32 and the notches 33 of the plate 23. May be. Or you may change the attachment angle of the cutting blade 3 with respect to the plate 23 by using properly the some cutting blade 3 from which the position of the long hole 31 with respect to the circular hole 32 differs. As a result, the angle of the cutting blade 3 with respect to the flooring 100 is adjusted, so that the cutting depth by the cutting blade 3 is adjusted.

  Since the cutting blade 3 may be worn or damaged by cutting, it needs to be replaced periodically. For this reason, it is desirable that a commercially available inexpensive blade having the same specifications is used as the cutting blade 3. Further, it is desirable that the cutting blade 3 is always attached to the plate 23 at a predetermined position and angle so that the angle of the cutting blade 3 with respect to the floor material 100 is not unintentionally changed when the blade is replaced. However, in order to easily adjust the cutting depth of the cutting blade 3, it is desirable that the floor material cutting machine 1 has a configuration capable of adjusting the angle of the cutting blade 3. Therefore, the floor material cutting machine 1 further includes an angle changing mechanism 7 that changes the angle of the cutting blade 3 with respect to the floor material 100 in order to adjust the cutting depth as a cutting depth adjusting mechanism.

  FIG. 6 schematically shows the angle changing mechanism 7. More specifically, FIG. 6 is a cross-sectional view of a set of assemblies including a set of plates 23, a connecting plate 24, and a front end portion 25 as viewed in the A direction on a plane orthogonal to the longitudinal direction of the plates 23. (See FIG. 1). The front end 25 on the back side of the connecting plate 24 is indicated by a dotted line. The angle changing mechanism 7 changes the angle of the cutting blade 3 with respect to the floor material 100 by changing the mounting height of the plate 23 to which the cutting blade 3 is fixed with respect to the wheel 4. The plate 23 is attached to the wheel 4 via a connecting plate 24, a front end portion 25, and a wheel fixing portion 26. As described above, the connecting plate 24 connected to the plate 23 is connected to the front end portion 25 by the connecting screw 80, the front end portion 25 is connected to the wheel fixing portion 26 and the screw 81, and the wheel 4 is connected to the wheel fixing portion 26. Fixed to be rotatable. As shown in FIG. 6, the connecting plate 24 has two long holes 71. For this reason, the attachment height with respect to the front-end part 25 of the connection board 24 can be changed by changing the fastening position of the connection screw 80 within the range of the long hole 71. As a result, the mounting height of the plate 23 with respect to the wheel 4 is also changed.

  Hereinafter, the angle changing mechanism 7 will be further described with reference to FIGS. 2 and 3. FIG. 3 is a partial side view of the floor cutting machine 1 according to the present invention in a state where the angle of the cutting blade 3 with respect to the floor 100 is changed by the angle changing mechanism 7. 2 and 3, the weight 6 is indicated by a dotted line.

  In FIG. 2, the connecting screw 80 is fastened to the female screw hole in the front end portion 25 at the position shown in FIG. 6, and the angle formed by the cutting blade 3 and the flooring material 100 is 135 °. In FIG. 3, the connecting screw 80 is fastened to the female screw hole in the front end portion 25 at the upper end portion of the long hole 71 of the connecting plate 24, and the angle formed by the cutting blade 3 and the flooring material 100 is 127.48 °. As a matter of course, if the length of the long hole 71 of the connecting plate 24 is increased, the angle adjustment range can be widened. Moreover, the angle with respect to the flooring 100 of the cutting blade 3 in FIG. 2 serving as a reference can be changed by changing the mounting angle of the cutting blade 3 with respect to the plate 23.

  The floor material cutting machine 1 also includes a load changing mechanism that changes the load on the cutting blade 3 so as to adjust the cutting depth by the cutting blade 3 as a cutting depth adjusting mechanism. The load changing mechanism changes the load on the cutting blade 3 by adjusting the position of the weight 6 with respect to the cutting blade 3. FIG. 7 shows a bottom view of the weight 6. The material of the weight 6 is, for example, iron plated with gold, silver, zinc or the like. A rectangular groove 61 in which the plate 23 is accommodated is provided below the weight 6. A circular through hole penetrates from one side of the weight 6 to the groove. On the other hand, as shown in FIGS. 2 and 3, the plate 23 is provided with a plurality of female screw holes 84 at equal intervals along the longitudinal direction near the upper end portion thereof. The plate 23 is housed in the groove of the weight 6, and the fixing screw 82 is passed through the circular hole 32 of the weight 6 and the female screw hole 84 of the plate 23 is aligned with the through hole of the weight 6. The weight 6 is fixed to the plate 23 by being fastened to the screw hole 84. When the fixing screw 82 is loosened, the weight 6 can slide on the plate 23 along the longitudinal direction of the plate 23. For this reason, the position of the weight 6 with respect to the cutting blade 3 can be easily changed by fixing the weight 6 to the plate 23 using another female screw hole 84.

  When the floor material cutting machine 1 is disposed on the floor material 100, the position at which the cutting blade 3 contacts the floor material 100, the position of the connecting plate 24 that connects the plate 23 and the front end portion 25, and the cutting blade 3. The position of the weight 6 that applies a load to the load can be regarded as an action point, a fulcrum, and a force point. When the position of the weight 6 with respect to the cutting blade 3 is changed by the method described above, the position of the force point with respect to the fulcrum and the action point is changed, so that the load on the cutting blade 3 is changed. The further the force point is away from the fulcrum, the greater the load on the cutting blade 3. That is, as shown in FIGS. 2 and 3, when the weight 6 is fixed to the plate 23 at a position farthest from the connecting plate 24, the load on the cutting blade 3 and the cutting depth by the cutting blade 3 become maximum. .

  As shown in FIG. 1, the floor material cutting machine 1 includes a plurality of pairs of cutting blades 3 and weights 6. The position of each weight 6 with respect to the corresponding cutting blade 3 is adjusted for each pair of cutting blades 3 and weights 6. In other words, the load changing mechanism is provided for each of the pair of cutting blades 3 and the weights 6 and can adjust the load on each cutting blade 3 independently. For this reason, cutting is performed by increasing the load on the cutting blade 3 whose wear is severe and the cutting depth is shallow and / or reducing the load on the new cutting blade 3 having a deep cutting depth. The blade 3 can be prevented from coming into contact with the floor 101 and the replacement frequency of the cutting blade 3 can be reduced to extend the life of the cutting blade 3. This results in faster work and reduced costs.

  The handle 5 is fixed to the front shaft 21 of the main body 2 and extends perpendicularly to the axial direction from the front shaft 21. The handle 5 is also made of metal, and the handle 5 and the front shaft 21 are typically connected by welding. Since the front shaft 21 can rotate about its axial direction, the handle 5 can also rotate about the axial direction of the front shaft 21, and the height of the grip 51 of the handle 5 is an appropriate height depending on the operator. Can be changed. For this reason, the operator can pull the floor material cutting machine 1 in an easy posture. Further, the handle 5 is swingable so that the gripping portion traverses the main body 2. Therefore, when the worker cannot stand the front of the wheel 4 and pull the floor cutting machine 1 due to a front obstacle such as a wall, the operator swings the handle 5 and moves the gripping part behind the tail part 27. By moving, the floor material cutting machine 1 can be pushed in the direction of the obstacle. For this reason, it becomes possible to cut also the flooring 100 in the position close to the obstacle.

  The handle 5 may be extendable and retractable so that the length can be adjusted during operation and / or can be divided at a branching portion 52 (see FIG. 1) on the front shaft 21 side. When the handle 5 is splittable, the portion that is split and left in the main body 2 can be folded inside the main body 2 by rotating the front shaft 21 around its axis. The tail portion 27 of the main body 2 can also be folded inside the main body 2 by rotating the rear shaft 22 around its axis. Accordingly, the floor material cutting machine 1 is greatly reduced in height and horizontal width. For this reason, in a state where the floor material cutting machine 1 is housed in a dedicated case, the floor material cutting machine 1 can be easily carried manually by grasping the handle of the case. This is because when the floor cutting machine 1 is brought into a high floor of an apartment like a condominium, the floor cutting machine 1 can be carried quickly using an elevator without generating noise. Is a big advantage. In this case, the divided handle 5 is carried separately from the case and assembled to the main body 2 at the work site.

  Hereinafter, the floor material peeling method using the floor material cutting machine 1 will be described in detail. First, the floor material cutting machine 1 is placed on the floor material 100 attached to the floor 101.

  Next, the floor material 100 is cut with the floor material cutting machine 1. In order to cut the flooring material 100, the operator reciprocates on the flooring material 100 over a predetermined range while standing in front of the wheel 4 and pulling the flooring material cutting machine 1 with the handle 5. When there is an obstacle ahead, the operator moves the grip portion of the handle 5 to the rear of the tail portion 27 of the main body 2 and then stands behind the tail portion 27 and pushes the floor material cutting machine 1 to press the floor material. 100 is cut. Before and / or during this operation, the thickness of the flooring 100 (typically about 1.5 to 2.0 mm) and the state of the cutting blade 3 are set so that the cutting blade 3 does not contact the floor 101. Accordingly, the cutting depth of the cutting blade 3 is adjusted by the above-described cutting depth adjusting mechanism (load changing mechanism and / or angle changing mechanism). After the cutting, the floor material 100 is manually torn along the cutting marks and peeled off from the floor 101.

  In this method, no noise is generated by the drive unit for causing the apparatus for separating the floor material 100 to self-run, and the cutting blade 3 does not contact the floor 101. For this reason, the noise which cuts the flooring material 100 is reduced, and the noise accompanying the removal work of a flooring material is also reduced by extension. Furthermore, in this method, since the operator can cut the flooring material 100 by pushing and pulling the flooring material cutting machine 1 in a standing posture, the flooring material 100 can be easily and quickly removed. it can.

  As mentioned above, although several suitable embodiment which concerns on this invention was described, this invention is not limited to these embodiment, A various correction and change can be given within description of a claim. . For example, the floor material cutting machine described above desirably cuts the floor material with a cutting blade, but the floor material may be cut with the cutting blade. The floor material cutting machine described above can be used not only for removing floor materials such as open corridors and roof balconies, but also for removing vinyl chloride waterproof sheets laid on the rooftop.
